Pnp AlGaN/InGaN/GaN Double Heterojunction Bipolar Transistors With Low-Base-Resistance (<100 Ω/square)
|
We investigated the current–voltage characteristics of pnp AlGaN/InGaN/GaN double heterojunction bipolar transistors grown by metalorganic vapor phase epitaxy. The InGaN base layer was heavily doped with Si in the range from 4×1019 to 2×1020 cm-3. Base sheet resistance was less than 100 Ω/square for the base width of 30 nm and Si-doping concentration of 2×1020 cm-3. This is the lowest resistance ever reported for nitride-based heterojunction bipolar transistors. In this device, the current gain was 2.7 at the collector current of 23 mA. We observed no significant degradation in the crystal quality of InGaN in separate Hall-effect measurements of Si-doped InGaN and in the device operation, even though the Si-doping concentration was above 1020 cm-3. The capability to decrease the base resistance will be advantageous for high-frequency operation.

Surface brightness and evolution of galaxies
|
It is well known that before the redshift-magnitude diagram of galaxies could be used for determination of the cosmological parameters one must know the evolution of the galaxies. We propose use of apparent surface brightness: which depends only on the redshift and is independent of the cosmological model and the inhomogeneities in the universe: for observational determination of the evolution of galaxies. The needed observations are isophotal angular diameters and apparent magnitudes within this or any other reasonable angular diameter. The application of the results for determination of q/sub 0/ is discussed briefly. (AIP)

Enhancement of ultrasonic surface waves at wedge tips and angled defects
|
The behaviour of sound waves interacting with wedges has attracted interest from researchers in geophysics and non-destructive testing. We consider here the near-field behaviour of Rayleigh waves incident on wedges and surface-breaking defects which propagate at an angle to the surface, such as rolling contact fatigue on rails. It has been shown that, for a detection point on the edge of the crack tip, a very large signal enhancement is observed for shallow angles. We explain this behaviour through considering the effect of the defect geometry, with changes in the frequency·thickness product leading to mode-conversion of the incident Rayleigh wave.

Electron backscatter diffraction of a pre- and post-deformation Ti-6Al-4V Taylor impact specimen
|
Titanium alloys have seen wide spread, and ever increasing, use in the aerospace industry, due to a high specific strength and good resistance to corrosion. However, current understanding of the deformation mechanisms of Titanium alloys under complex high strain rate loading is limited. In order to improve understanding in this area, post-deformation microstructural analyses of Titanium alloys loaded under well controlled, but complex, high strain rate loading conditions, such as the Taylor impact test, are required. This paper presents the initial results of a program of Taylor impact experiments carried out on heavily textured Ti-6Al-4V plate. An optical measurement technique was used to provide data on the anisotropic deformation of the specimen, providing a full strain path history along the axial length of the specimen. Electron backscatter diffraction analysis was performed on the pre and post-deformation specimen with comparisons made between the deformed and undeformed microstructures.

Using Composite Resin Inclined Plane for the Repositioning of a Laterally Luxated Primary Incisor: A Case Report
|
This case report describes the repositioning of a laterally luxated primary central incisor with occlusal interference, using a composite inclined plane. The patient was a 4-year-old girl who applied to our clinic three days after the injury. Because of the time delay between injury and presentation, it was not possible to reposition the tooth with pressure. Following a root-canal treatment, an inclined plane was prepared on the lower primary incisors, using composite resin. The tooth was repositioned in two weeks, and the inclined plane was then removed. After 1 year of follow-up, the treatment was found to be successful, both clinically and radiographically. The use of a composite inclined plane, accompanied by careful follow-up, is an effective alternative to extraction for laterally luxated primary incisors with occlusal interference.

Characterizing Statistical Cells Timing Metrics with Semi-Monte-Carlo Method
|
Monte Carlo (MC) method is the standard method to characterize statistical moments of cell delays and slopes. However, this method suffers from very high computational cost. In this paper, we propose a technique to quickly and accurately estimate Standard Deviation (SD) of standard cell delays and slopes. The proposed technique is based on the identification, performed with a reduced set of MC simulations, of delay and output slope SD functions that take input slope, output load and supply voltage as input arguments. These identified functions are then used to estimate SDs of delays and slopes at different operating conditions (input slope, output load, supply voltage). This proposed method provides at least ퟕퟔ% of CPU gains, with respect to MC, while keeping high accuracy.

Development of Pyramidia: An Integrative E-Learning Multimedia Tool
|
The software package described in this paper, Pyramidia, combines two strong elements into one lecturing system. The first is the simple addition of content and interactivity to existing PowerPoint presentations, and the second is video capture of a lecture. These features provide obvious benefits for both sides of the lecturing process: the lecturers and the students. Students can re-experience lectures at anytime, anywhere and at their own pace. Lecturers can add interactivity to their lectures without worrying about learning complex new software. Pyramidia is a descendant of previous software developments and research on ICT usage in education, and has been used and tested throughout a few semesters of lectures for several courses. Although there are many solutions, both commercial and academic, available to potential users, Pyramidia is unique for its. NET framework programming base.

Language, Person, and Place: Echoes of Religion in Minority Literatures
|
Minority literature, whether produced by prominent authors writing in marginalized languages or marginalized authors writing in dominant languages, raises questions of human identity and alienation, human location and dislocation, which resonate with characteristically religious strategies for negotiating what it means to be a human being in a human place. This essay suggests that we can find traces of “religious” themes in ::: the work of authors of minority literature who operate on the margins and at the creative intersections between the living and the dead, between home and diaspora, and between singular and multiple realms of meaning. Journal for the Study of Religion Vol. 19 (2) 2006: pp. 5-16

Optimal retirement planning under partial information
|
Abstract The present paper analyzes an optimal consumption and investment problem of a retiree with a constant relative risk aversion (CRRA) who faces parameter uncertainty about the financial market. We solve the optimization problem under partial information by making the market observationally complete and consequently applying the martingale method to obtain closed-form solutions to the optimal consumption and investment strategies. Further, we provide some comparative statics and numerical analyses to deeply understand the consumption and investment behavior under partial information. Bearing partial information has little impact on the optimal consumption level, but it makes retirees with an RRA smaller than one invest more riskily, while it makes retirees with an RRA larger than one invest more conservatively.

Adaptation to stress in yeast: to translate or not?: Figure 1
|
For most eukaryotic organisms, including Saccharomyces cerevisiae, the rapid inhibition of protein synthesis forms part of a response to stress. In order to balance the changing conditions, precise stress-specific alterations to the cell's proteome are required. Therefore, in the background of a global down-regulation in protein synthesis, specific proteins are induced. Given the level of plasticity required to enable stress-specific alterations of this kind, it is surprising that the mechanisms of translational regulation are not more diverse. In the present review, we summarize the impact of stress on translation initiation, highlighting both the similarities and distinctions between various stress responses. Finally, we speculate as to how yeast cells generate stress-responsive programmes of protein production when regulation is focused on the same steps in the translation pathway.

THE DYNAMIC RESPONSE OF FRP-RC FRAMES
|
A theoretical analysis of the dynamic response of FRP-RC beam and frame structures is performed in this paper. Bending and shear stiffness of carbon fiber wrapping concrete beams are obtained from the non-classical theory. ANSYS software is used to analyze the dynamic response of the structures. A single beam and a single-layer and single-span frame are taken as examples and the results are compared to those obtained from ANSYS 3D analysis. It is clearly demonstrated that the method used in the present research is much more convenient and highly efficient.

"Being bridges": Cleaver/Baldwin/Lorde and African-American sexism and sexuality.
|
In an attempt to place James Baldwin and his ideas within a context of a debate on black sexuality and sexism, this paper begins with a section on Elridge Cleaver and his critique of Baldwin's position on sexuality and race. The second section takes up Baldwin explicitly and attempts both to outline his position more fully and to suggest the breadth and depth of his analysis of sexuality and the work yet to be done to chart it. In the final section I turn to Audre Lorde in order to update the critique of Baldwin's position within the debate;

Features of gadolinium and ytterbium extraction by tributyl phosphate from concentrated nitric acid solutions. II. IR spectra of lanthanide extracts
|
Equilibrium organic phases in extraction systems consisting of tributyl phosphate (TBP) (neat or 1.8 M in CCl{sub 4}) and 8-12 M nitric acid containing Gd or Yb or lanthanide-free have been studied by IR spectroscopy. It was shown that under these conditions lanthanides are extracted as complex trisolvates Ln(NO{sub 3})9{sub 3}{center_dot}mHNO{sub 3}{center_dot}3TBP with m = 3-6. Nitric acid molecules are H-bonded to oxygen atoms of coordinated nitrate ions and do not substitute TBP molecules in coordination sphere of the metal ion.

Side effects of ovulation inhibitors
|
Since ovulation inhibitors may affect many different parts and systems of the body their prescription should not be limited to gynecologists alone. Warnings listing all clinically significant symptoms on or in the packages would be helpful. The author knows of no tests for epithelial degeneration which have further enlightened the field or justified concern in this area. Regular examinations for liver damage blood coagulation or eye problems are not necessary since doctors now are so well-informed that they would be able to interpret clinical symptoms for identifying conditions requiring specialized treatment. As of now long-term studies of healthy girls and women on oral contraceptives are lacking. Care must be taken to differentiate between effects of contraceptives and those of a constantly changing enviornment.

Jews and Freemasons in Europe 1723-1939
|
The theme of this book-the relation between Jews and Freemasons-has been the subject of countless books written, mainly in German and French, by propagandists of anti-Jewish or anti-Masonic leanings or by apologists in counterargument. Historians, however, have paid little if any attention to this subject. This is not surprising, for to the scholar presumed connection between Jews and Freemasons seemed little more than myth; any sources that could have clarified the assumption were hidden in the libraries and archives of the Masons, and usually inaccessible to the probing historian.

First Report of Rubber Tree Stem Rot Caused by Fusarium oxysporum in China
|
Rubber tree (Hevea brasiliensis) is an important crop in tropical regions of China. In October 2013, a new stem rot disease was found on cv. Yunyan77-4 at a rubber tree plantation in Hekou, Yunnan Province. There were about 100 plants, and diseased rubber trees accounted for 30% or less. Initially, brown-punctuate secretion appeared on the stem, which was 5 to 6 cm above the ground. Eventually, the secretion became black and no latex produced from the rubber tree bark. After removing the secretion, the diseased bark was brown putrescence, but the circumambient bark was normal. Upon peeling the surface bark, the inner bark and xylem had brown rot and was musty. The junction between health and disease was undulate. On the two most serious plants, parts of leaves on the crown were yellow, and the root near the diseased stem was dry and puce. The pathogen was isolated and designated HbFO01; the pathogenicity was established by following Koch's postulates. The pathogen was cultivated on a potato dextrose agar ...

BLOOD CHEMISTRY OF THE WEST INDIAN MANATEE (TRICHECHUS MANATUS) 1
|
Blood from 10 clinically healthy West Indian manatees (8 wild, 2 captive) was analyzed for the common blood chemical substances. No sex differences were found. The results were comparable for the most part to those of the common domestic mammals. Notable exceptions were the anion gaps, and total proteins and A/G ratios which were higher than those for domestic species. Some of these differences were no doubt due to the stress of capture.

Integrated service navigation framework for ubiquitous networking
|
A huge amount of service components will soon be deployed to ubiquitous networks. Each will provide a simple service, but compositions of service components are expected to be highly valuable to users, because it is hard for users to find and combine adequate service components. We are developing a service navigation architecture in which a composite service is assembled from service components autonomously. We point out four issues to be addressed in the architecture: autonomy, efficiency, security, and reliability. In our architecture, these issues are handled by integrating management of applications and the management of networks. In this paper, we explain the technologies we are developing for this integrated management.

Applications of epitope tag technology in membrane protein research
|
The research on membrane proteins aims to investigate subcellular trafficking and localization of membrane proteins, structural and functional characterization of membrane proteins, and interactions between membrane proteins and other relevant proteins. Based on the topological prediction of membrane proteins of interest, appropriate epitope tags are selected and fused to membrane proteins at genetic level with gene fusion technology. Resultant tagged membrane proteins may have functions of original membrane proteins together with biochemical properties of the imparted fusion tags that can be recognized by specific antibodies, which greatly enhance the functional and structural study of membrane proteins by means of techniques such as immunotechnology. In this article, the latest bibliography related to applications, strategies, and approaches of epitope tagging technology in membrane proteins research are reviewed.

Mechanically agitated gas-liquid reactors
|
The hydrodynamic, heat and mass transfer characteristics of mechanically agitated contactors have been critically reviewed. The mixing time (θmix) can be correlated well by a model based on circulation path and average circulation velocity. Flow patterns in mechanically agitated contactors (single phase) provided with disk turbine, pitched blade turbine and propeller can be characterised. The minimum impeller speed required for the gas induction (Ncr) in hollow shaft impellers can be predicted; the minimum impeller speed required for surface aeration (Ns) can also be predicted. ::: ::: Different strategies of operating mechanically agitated contactors have been examined. The advantages of multistage contactors over single contactors have been stressed. ::: ::: Recommendations have been made for correlations which can be used for design purpose; lacunae in the available literature have been delineated and recommendations for further work have been made.

Towards Unstructured Mesh Generation Using the Inverse Poisson Problem
|
A novel approach to unstructured quadrilateral mesh generation for planar domains is presented. Away from irregular vertices, the resulting meshes have the properties of nearly conformal grids. The technique is based on a theoretical relation between the present problem, and the inverse Poisson (IP) problem with point sources. An IP algorithm is described, which constructs a point-source distribution, whose sources correspond to the irregular vertices of the mesh. Both the background theory and the IP algorithm address the global nature of the mesh generation problem. The IP algorithm is incorporated in a complete mesh generation scheme, which also includes an algorithm for creating the final mesh. Example results are presented and discussed.

Magnetic Resonance Imaging Quantification of GastrointestinalLiquid Volumes and Distribution in the Gastrointestinal Tract of Children
|
The volume and localization of fluid in the paediatric gastrointestinal tract is crucial to the design of in vitro and in silico models that predict the absorption of oral drugs administered to children. Previous studies have used magnetic resonance imaging (MRI) to quantify fluid volumes and localization in the intestines of adults; this study is the first to undertake similar analysis of pediatric participants. This study quantified the amount and distribution of fluid in fasted and fluid-fed children using MRI data captured during the routine clinical assessment. Data from 32 fasted children (aged 0–16 years) and 23 fluid-fed children (aged 8–16 years) were evaluated. The gastric volume ranged from 0 to 9 mL in the fasted and 19–423 mL in the fluid-fed state. The small intestinal volume was recorded to be 0–51 mL in the fasted and 6–91 mL in the fluid-fed state with an average number of 7.7 and 22.4 fluid pockets, respectively. The data showed significant differences in gastric volumes and the number o...

House Prices, Household Credit, and Financial Technology
|
I use peer-to-peer (P2P) credit markets to study how innovations in housing affect households' unsecured credit decisions. Driven by homeowners, I find that a one standard deviation increase in house price growth causes loan origination growth to decrease by 44% of its mean. Conversely, renters switch to P2P loans when housing markets are strong and traditional credit is scarce. Strong housing markets also lead to rising defaults by renters. Overall, developments in housing markets have important implications for evolving credit markets.

Specification and Analysis of Parallel Machine Architecture
|
Abstract : The objective of this research was to develop an environment in which a software application, target hardware architecture, and resource allocation strategy can be defined, simulated and evaluated. The motivation for this research was to provide ISC, particularly ISSC, methods for testing the performance of a given application or set of applications on a set of candidate host computers. The tools designed under this project can be used to evaluate the performance of large Ada programs running on POSIX compliant operating systems, as well as less conventional computer architectures. The first year results reported herein include a survey of existing methods/tools and the design of software and parallel architecture representation language. Based on the survey, the Berkeley Requirements Statement Language (BRSL) was extended making it suitable for the high level specification and analysis for both software and hardware of parallel machine architecture.

Local vascular contribution of the superficial palmar arch.
|
The aim of the present study was to establish a precise topography of the arterial supply of the different layers in the palm of the human hand. Two hundred upper extremities from fresh human cadavers aged 20-80 years were injected either by coloured latex or by India ink and gelatine. Some of our specimens were treated by the Spalteholz technique of transclarification, while some others were treated by acid corrosion. All of the specimens were dissected under the dissecting microscope. The superficial palmar arch (SPA) is the main vascular structure of the palm of the hand. Regardless of its size and of its variation, in addition to the common palmar digital arteries, the SPA supplies the superficial flexor tendons, flexor retinaculum, median and ulnar nerves, tendon of the flexor pollicis longus muscle, lumbrical muscles, palmar aponeurosis and the skin of the palm of the hand. These data may be of interest to those involved in hand surgery.

A Database of Formation Enthalpies of Nitrogen Species by Compound Methods (CBS-QB3, CBS-APNO, G3, G4).
|
Accurate thermochemical data for compounds containing C/H/N/O are required to underpin kinetics simulation and modeling of the reactions of these species in different environments. There is a dearth of experimental data so computational quantum chemistry has stepped in to fill this breach and to verify whether particular experiments are in need of revision. A number of composite model chemistries (CBS-QB3, CBS-APNO, G3, and G4) are used to compute theoretical atomization energies and hence enthalpies of formation at 0 and 298.15 K, and these are benchmarked against the best available compendium of values, the Active Thermochemical Tables or ATcT. In general the agreement is very good for some 28 species with the only discrepancy being for hydrazine. It is shown that, although individually the methods do not perform that well, collectively the mean unsigned error is <1.7 kJ mol–1; hence, this approach provides a useful tool to screen published values and validate new experimental results. Using multiple mo...

The Effect of Inclined Suction Nozzles on Vaccum Pneumatic Conveyor System Performance
|
Suction nozzles have been used for many years as the entraining device for the vacuum pneumatic unloading of bulk commodities from the holds of ships of all sizes. Much research work has been undertaken to improve the performance of these devices when used in a vertical attitude. However, the operation of these nozzles is often at an angle other than vertical due to the way in which the devices are manhandled. This paper presents the findings of an initial programme of work undertaken to assess the effect on the performance of vacuum pneumatic ship unloaders when the suction nozzle is presented to the material to be off-loaded at an angle inclined to the vertical. A range of products have been tested to assess whether product characteristics have an effect on the sensitivity of the vacuum pneumatic conveying system to the nozzle angle.

An Experimental Study of Fatigue Strength for Adhesively Bonded Tubular Single Lap Joints
|
Abstract In this paper, manufacturing technology of the tubular single lap adhesive joint was studied to obtain reliable and optimal joint quality. In addition, a surface preparation method and a bonding process for the joint were devised. The effect of the adhesive thickness and the adherend roughness on the fatigue strength of the joint was experimentally investigated. From experiments, it has been found that the fatigue strength of the joint increased as the adhesive thickness decreased and the optimal arithmetic surface roughness of the adherends was about 2 μm.

Prime normal form and equivalence of simple grammars
|
A prefix-free language is prime if it cannot be decomposed into a concatenation of two prefix-free languages. We show that we can check in polynomial time if a language generated by a simple context-free grammar is prime. Our algorithm computes a canonical representation of a simple language, converting its arbitrary simple grammar into prime normal form (PNF); a simple grammar is in PNF if all its nonterminals define primes. We also improve the complexity of testing the equivalence of simple grammars. The best previously known algorithm for this problem worked in O(n13) time. We improve it to O(n7 log2 n) and O(n5 polylog v) time, where n is the total size of the grammars involved, and v is the length of a shortest string derivable from a nonterminal, maximized over all nonterminals.

Optimization of crossover frequency and crossover region response for multichannel acoustic applications
|
Given a multichannel loudspeaker system, in a typical single or multiple listener setup, the selection of the crossover frequency between the sub-woofer and the satellite speakers is important for accurate reproduction of playback sound from the corresponding channels. Specifically, the combined sub-woofer and satellite room acoustical response should exhibit negligible variations around the selected crossover frequency and simultaneously allow accurate rendition of audio from the respective channels. In many instances, even after selecting an appropriate crossover frequency, the final combined response may yet have substantial variations that further need to be minimized. In this paper, we present a two-stage approach for minimizing the variations in the combined sub-woofer and satellite room response measured at a given listening position for multichannel audio applications.

Penicillium marneffei fungemia in an AIDS patient: the first case report in Taiwan.
|
Abstract We report a 36-year-old man with acquired immunodeficiency syndrome (AIDS), presenting systemic Penicillium marneffei (PM) infection. Fungal culture from the blood isolated PM. PM-induced enteritis was also suspected in this patient although there was no direct evidence. He also had other manifestations of immunocompromised status, including military tuberculosis and oral candidiasis. He died of respiratory failure in spite of prompt treatment for infection. This is the first confirmed case of PM infection in Taiwan.

education (U=971.5, p=0.03), cardio respiratory fitness (F1,99=21.57, p=0.00) and exercise self-efficacy (F1,99=39.56, p=0.00) and higher resting diastolic blood pressure (F1,99=7.57, p=0.01) and BMI (F1,99=33.63, p=0.00). The barrier items of perceived lack of time, difficulty getting to an exercise location and the weather provided the greatest discrimination between exercisers and non-exercisers. However, the acute exercise bout produced higher positive well-being postexercise compared to pre and during exercise for both groups. Conclusions: Identification of the differences in exercise behaviour between exercisers and non-exercisers may provide information for future health promotion policy directions for this population and allow for the formulation of guidelines for exercise professionals.

Linux kernel vulnerabilities: State-of-the-art defenses and open problems
|
Avoiding kernel vulnerabilities is critical to achieving security of many systems, because the kernel is often part of the trusted computing base. This paper evaluates the current state-of-the-art with respect to kernel protection techniques, by presenting two case studies of Linux kernel vulnerabilities. First, this paper presents data on 141 Linux kernel vulnerabilities discovered from January 2010 to March 2011, and second, this paper examines how well state-of-the-art techniques address these vulnerabilities. The main findings are that techniques often protect against certain exploits of a vulnerability but leave other exploits of the same vulnerability open, and that no effective techniques exist to handle semantic vulnerabilities---violations of high-level security invariants.

DESY 01-103 Speeding up the Hybrid-Monte-Carlo algorithm for dynamical fermions
|
Abstract We propose a modification of the Hybrid-Monte-Carlo algorithm that allows for a larger step-size of the integration scheme at constant acceptance rate. The key ingredient is the splitting of the pseudo-fermion action into two parts. We test our proposal at the example of the two-dimensional lattice Schwinger model and four-dimensional lattice QCD with two degenerate flavours of Wilson-fermions.

Magnetic design of a 14 mm period prototype superconducting undulator
|
Abstract In this paper we report the design of a 14 mm period prototype superconducting undulator that is under fabrication at Insertion Device Development Laboratory (IDDL) at Devi Ahilya Vishwavidyalaya, Indore, India. The field computations are made in RADIA and results are presented in an analytical form for computation of the on axis field and the field on the surface of the coil. On the basis of the findings, a best fit is presented for the model to calculate the field dependence on the gap and the current density. The fit is compared with Moser-Rossmanith formula proposed earlier to predict the magnetic flux density of a superconducting undulator. The field mapping is used to calculate the field integrals and its dependence on gap and current densities as well.

Radiation-induced chromosome aberrations analysed by fluorescence in situ hybridization with a triple combination of composite whole chromosome-specific DNA probes.
|
Fluorescence in situ hybridization (FISH) with a combination of three composite whole chromosome-specific DNA probes for human chromosomes 1, 4 and 12 was used to analyse in vitro radiation-induced dicentrics and symmetrical translocations in peripheral lymphocytes. Translocations could be rapidly and efficiently detected by FISH. Their frequencies were 1.8-fold higher than the frequencies for dicentrics at a given dose. The dose-response curves for translocations and dicentrics were linear quadratic with a significant higher quadratic component for translocations. The application of FISH for scoring stable translocations for biological dosimetry of radiation exposures is discussed.

Automatic structures, rational growth, and geometrically finite hyperbolic groups
|
We show that the set\(S\mathfrak{A}(G)\) of equivalence classes of synchronously automatic structures on a geometrically finite hyperbolic groupG is dense in the product of the sets\(S\mathfrak{A}(P)\) over all maximal parabolic subgroupsP. The set\(BS\mathfrak{A}(G)\) of equivalence classes of biautomatic structures onG is isomorphic to the product of the sets\(BS\mathfrak{A}(P)\) over the cusps (conjugacy classes of maximal parabolic subgroups) ofG. Each maximal parabolicP is a virtually abelian group, so\(S\mathfrak{A}(P)\) and\(BS\mathfrak{A}(P)\) were computed in [NS1].

Role of Dried Fenugreek (Trigonella Foenum-graecum L.) Leaves as Antioxidant and Antimicrobial in Quality Preservation in Burgers Made of Mutton and Beef Cattle Meat During Refrigerator Storage
|
The effect of different levels of crud fenugreek leaves on lipid oxidation and microbial spoilage of mutton and beef cattle meat postmortem refrigerated storage was examined. Samples meat of mutton and beef cattle were incorporated with crud fenugreek leaves at four different levels 0, 0.5, 1.0 and 1.5 %. Mutton and beef meat in burgers form were subjected to 7 and 10 d postmortem refrigerated storage. Mutton and beef cattle meat marinated with crud fenugreek leaves had significantly lower content of malondialdehyde (MDA) at day 7 and 10 postmortem, respectively. Bacterial counts was lower (p<0.05) in mutton and beef cattle meat contenting crud fenugreek leaves compared to control at 3, 5, 7 and 10 postmortem. Regardless of treatment, postmortem refrigerated storage influenced oxidative and microbial stability of meat. Adding crud fenugreek leaves into mutton and beef cattle meat exhibited effective antimicrobial properties and high antioxidant activity.

A method to detect lap splice in reinforced concrete using a combination of covermeter and GPR
|
Abstract A method to detect a lap splice and to estimate a summation of a diameter of the two rebars of the lap splice in reinforced concrete based on a combined utilization of covermeter and ground penetrating radar (GPR) is proposed. The performance of the proposed method is compared with the case that only one instrument is employed. The results show that the proposed method can detect the type of overlapping direction of the lap splice and estimate the summation of the diameter of the two rebars with an average error of 2.35% and standard error of estimate of 1.34 mm.

Review of the techniques for gray image 3D reconstruction
|
The basic principle and contents of Shape From Shading(SFS) are expounded systematically.In terms of solution method and illumination model,the main problems of current SFS algorithms are analyzed.It is found that,the solution of a classical SFS algorithm is complex,it strongly depends on the initial conditions and boundary constraints,besides,as the actual surface of an object does not always match with the Lambertian reflection,the accuracy of a SFS algorithm is sometimes seriously poor.In addition,the importance of the illumination model in solving above problems is stressed,and some new ideas are put forward for further study.

Thermally Stimulated Currents by Charge-Generation Layer Excitation in Azo-based Layered Organic Photoconductors
|
Thermally stimulated currents (TSCs) were measured by exciting the charge-generation layer of layered organic photoconductors. Carrier-generation efficiency was measured in a very wide temperature range of irradiation. By this technique, the formation and successive processes of the initial ion pairs are separated because recombination and separation of the initial ion pairs are suppressed at low temperature. The carrier-generation efficiency of the layered photoconductors using azo pigments shows extremely weak dependences on both irradiation temperature and electric field below 160 K.

Homogeneous games as anti step functions
|
In this paper the class of homogeneousn-person games “without dummies and steps” is characterized by two algebraic axioms. Each of these games induces a natural vector of lengthn, called incidence vector of the game, and vice versa. A geometrical interpretation of incidence vectors allows to construct all of these games and to enumerate them recursively with respect to the number of persons.

|
The performance of superficial strained Si/Si1−xGex channel metal-oxide-semiconductor field-effect transistors has been described making use of a two-dimensional drift-diffusion simulator including inversion layer quantization and low-field mobility curves obtained by means of a Monte Carlo simulator. We have reproduced experimental results. In addition, the dependencies of the performance enhancement obtained in these devices on the germanium mole fraction and the drain-source and gate-source voltages are described in depth.

Light-Controlled Single-Walled Carbon Nanotube Dispersions in Aqueous Solution
|
We have succeeded in dispersing single-walled carbon nanotubes (SWNTs) into an aqueous solution of poly(ethylene glycol)-terminated malachite green derivative (PEG-MG) through simple sonication. It was found that UV exposure caused reaggregation of these predispersed SWNTs in the same aqueous medium, as adsorbed PEG-MG photochromic chains could be effectively photocleavaged from the nanotube surface. The observed light-controlled dispersion and reaggragation of SWNTs in the aqueous solution should facilitate the development of SWNT dispersions with a controllable dispersity for potential applications.

Decreased expression of the IGF-II gene during porcine adipose cell differentiation
|
Abstract IGF-I and IGF-II are known to regulate cell development and recent data suggest a possible role of IGF-II on adipose tissue development. This study was undertaken to examine the IGF system gene expression in porcine differentiating adipocytes. Both adipocytes and stromal–vascular (s/v) cells were isolated from subcutaneous adipose tissue collected from 7-day-old piglets. s/v cells were cultured in chemically defined medium. Compared with isolated adipocytes, IGF-II and IGFBP-5 mRNA levels were very high in freshly isolated s/v cells, whereas IGF-I mRNA levels were lower in s/v cells than in adipocytes. Between day 0 and day 6 of culture, IGF-II and IGFBP-5 gene expression decreased whereas expression levels of late markers of adipocyte differentiation were up-regulated. Cell differentiation was also associated with an increase in the expression of IGF-I, insulin and IGF receptor genes. The current findings suggest that IGF-I and IGF-II have different effects on porcine adipose cell development.

An Archival Treasure: The Irish Mermaid and Feminine Fertility
|
Unlike her counterparts from antiquity and the Middle Ages, whose seduction is deadly and evil, the Irish mermaid is attractive and fertile, she is a good wife and mother. The rituals and stories connected to her belong to an early European peasant calendar, that establishes a correspondence between the reproductive cycles of the earth, women and plants. Indeed this mermaid fits into a cyclical time where death is to the earth what menstruation is to women and flowering is to plants, fulfilling a fertile and nourishing potential.

Microbial lipids as potential source to food supplements
|
For centuries, men have used microorganisms for their activities and abilities to produce metabolites of interest such as antibiotics or pigments. Lipids are now under the spotlight as applications can be found in several domains such as in biofuels. Lipids formed by microorganisms can also be interesting from a dietary point of view, as some microorganisms (yeast, fungi, microalgae and Thraustochytrids) are able to produce polyunsaturated fatty acids (PUFAs). These PUFAs, such as those belonging to the omega-3 and omega-6 series, are known for their benefits to human health. The use of microorganisms represents a promising way to produce PUFAs at lower cost and with a higher yield. This manuscript discusses various potent microorganisms for single cell oils production designed for the dietary domain.

Boron-induced Morphology Changes in Silicon CVD Growth: A Scanning Tunneling Microscopy Study.
|
Abstract : Scanning tunneling microscopy has been used to investigate the influence of surface boron on silicon growth via chemical vapor deposition (CVD). The presence of boron-induced reconstructions on the Si(001) surface dramatically changes the surface morphology during subsequent CVD growth of silicon using disilane at 815 Kelvin. Boron-induced reconstructions inhibit the lateral diffusion of silicon atoms from terraces to step edges, leading to greatly enhanced island nucleation, and also reduce the local surface reactivity toward disilane. Strong segregation of boron to the growth surface allows the enhanced island nucleation to persist to subsequent terraces during multilayer CVD growth of silicon, producing a rough but epitaxial surface.

The Gastrodia elata genome provides insights into plant adaptation to heterotrophy
|
We present the 1.06 Gb sequenced genome of Gastrodia elata, an obligate mycoheterotrophic plant, which contains 18,969 protein-coding genes. Many genes conserved in other plant species have been deleted from the G. elata genome, including most of those for photosynthesis. Additional evidence of the influence of genome plasticity in the adaptation of this mycoheterotrophic lifestyle is evident in the large number of gene families that are expanded in G. elata, including glycoside hydrolases and urease that likely facilitate the digestion of hyphae are expanded, as are genes associated with strigolactone signaling, and ATPases that may contribute to the atypical energy metabolism. We also find that the plastid genome of G. elata is markedly smaller than that of green plant species while its mitochondrial genome is one of the largest observed to date. Our report establishes a foundation for studying adaptation to a mycoheterotrophic lifestyle.

The Fully Compressed String Matching for Lempel-Ziv Encoding
|
The growing importance of massively stored information requires new approaches to efficient algorithms on texts represented in a compressed form. We consider here the {\em string-matching} problem in the compressed setting. This problem has been already investigated in \cite{AB}, \cite{ABF2}, \cite{ABF1}. A rather theoretical type of compression was considered in \cite{KRS}. In this paper we consider a practically important compression algorithm of Lempel and Ziv ({\em LZ algorithm}, in short). Denote by $LZ(w)$ the compressed version of a given string $w$ using the LZ algorithm. The {\em \bf Fully Compressed Matching Problem} is that of deciding if the pattern $P$ occurs in a text $T$, given only $LZ(P)$ and $LZ(T)$, without decompressing the pattern and the text. The first occurrence is reported, if there is any. Let $m$ and $n$ denote the sizes of $LZ(P)$ and $LZ(T)$, and $M$, $N$ be the sizes of uncompressed strings $P$ and $T$, respectively.

Effect of sand on the vacuum consolidation of dredged slurry
|
ABSTRACTVacuum preloading is often used to improve the geotechnical properties of dredged slurry. Although the performance of this method has improved with rapidly developing technology, soil columns usually formed on the drainage boundary induce the decrease of permeability around the boundary, thereby limiting the further development of this method. To address this issue, this paper proposes a method for pretreating the slurry combined with sand prior to vacuum consolidation. This method partially replaces the fine particles with sand to reduce the formation of soil columns. Two groups of vacuum preloading tests were performed to investigate the effect of sand content and sand grain size on the vacuum consolidation of dredged slurry. The test results revealed that for a given sand grain size, increasing the sand content of the sand–slurry mixture increased the pore water drainage and accelerated the dissipation of pore water pressure, thereby increasing the vane shear strength. In contrast, for a consta...

PERFORMANCE OF COMMERCIALLY GROWN 'HASS' AVOCADO ON CLONAL ROOTSTOCKS AT WESTFALIA ESTATE, SOUTH AFRICA
|
SUMMARY The Californian clonal rootstocks Thomas, Barr Duke, D9, and Duke 7 have been tested on commercial scale, for the Hass cultivar, at three sites, since 1989. Individual tree yields and tree dimensions have been measured annually. Yield efficiency of Hass on D9 and Barr Duke was superior to Hass/Duke 7. Two local rootstock selections, Merensky 1 and Merensky 2, have also been tested commercially for Hass since 1994 and both have produced greater Hass yields than on Duke 7 rootstock, although in terms of yield efficiency, only Merensky II was superior to Duke 7. Phytophthora tolerance of these two local selections is also superior to Duke 7. Although it is still early in the commercial evaluation of these rootstocks, promising Phytophthora tolerance results have led to an early release of Merensky to local and overseas institutions for testing purposes.

Malic Enzyme of Escherichia coli DIVERSITY OF THE EFFECTORS CONTROLLING ENZYME ACTIVITY
|
Abstract The TPN+-specific malic enzyme from Escherichia coli has been purified from malate-grown cells. An approximately 100-fold purified preparation is activated by NH4+ and K+ ions. The enzyme is inhibited by acetyl coenzyme A, oxalacetate, TPNH, and DPNH in an allosteric manner. Glycine at concentration ranges above 0.5 m has been shown to activate the enzyme as well as to desensitize it reversibly to the effect of various inhibitors, including DPNH. From teleological arguments it has been concluded that the complex activity controls of malic enzyme are necessitated in bacteria because of the absence of rigid compartmentation controls available to higher organisms.

Studies on the Interaction of Surface Films with Solute in Solution. I. Potentiometric Titration of Aqueous Dye Solution and Calculation of Ionization Constant of Dye
|
Change of pH of aqueous dye solution was traced by titrating with the solution of hydrochloric acid or sodium hydroxide. From these data, ionization constants for each ionizing group in chrysoidine, methyl orange, tropaolin OO and aluminon were calculated, making use of equations based on the law of mass action with a specially-selected parameter. The validity of the ionization constants thus determined were confirmed by reasonable coincidence of the titration curves obtained by calculation using these data with those observed, over the wide range of pH. In the case of Congo red, however, it seemed better to treat it as a high-molecular electrolyte. Ionization constants calculated by an equation based on such a treatment explain the experimental result better than those based on the treatment similar to the case of other simple dyes.

Water metabolism of Merino sheep shorn during summer
|
Ten Merino wethers in the dry subtropical region of "Gilruth Plains", Cunnamulla, Qld., were shorn in November during a period of sunshine with maximum temperatures between 36 and 38°C. The content, distribution, and turnover of water were estimated before and after shearing. There was no significant change in total body water but the thiocyanate space increased by 12%, the plasma volume by 17%, and the plasma proteins were diluted by 17% after shearing. Water turnover rose from 81.5 to 159 ml/kg/24 hr. There was a correlation (v = 0.68) between the increase in respiratory rate which took place when the sheep were standing in the sun and the increase in water turnover during the same period. It is estimated that an average increment of 1550 kcal/24 hr in heat load from insolation occurred as a result of the removal of fleece during exposure to summer sun. The greater water turnover from evaporative cooling was associated with increased extracellular fluid space.

Clastic Huntite in Upper Neogene Formations of the Kozani Basin, Macedonia, Northern Greece
|
ABSTRACT An unusual carbonate mineral, huntite (Mg3Ca(CO3)4), is present in Upper Neogene lacustrine formations of the Kozani Basin, Northern Greece. This carbonate, either pure or mixed with variable proportions of hydromagnesite and magnesite, forms extensive deposits that accumulated in ponds on a lake-margin carbonate flat. Although labile and metastable, huntite also is the main detrital component of fluvial-dominated delta sequences in some parts of the basin. Clastic huntite is present mainly in foresets, trough cross-stratified units, and channel forms in terrigenous lithofacies towards the basal part of deltaic assemblages. Detachment of fragments from cohesive huntite pond deposits may have been favored by expansion through wetting rather than by desi cation and further contraction of the chemical sediment. This first documented occurrence of clastic huntite places some uncertainties on the presumed chemical and mechanical instability of huntite under natural conditions.

The Cauchy problem for quaternion fuzzy fractional differential equations
|
We discuss the existence of a solution to the Cauchy problem for fuzzy fractional differential equations that accommodates the notion of fuzzy sets defined by quaternion-valued membership functions. We first propose definitions of quaternion fuzzy sets and discuss entailed results which parallel those of regular fuzzy numbers. Two existence results, relevant to the Cauchy problem for fuzzy fractional differential equations in the case of bounded integral operators, are given. The results require either Holder continuous or Lipschitz continuous response functions.
