Effects of Herbal Enriched Artemia Supplementation over the Reproductive Performance and Larval Quality in Spent Spawners of the Tiger Shrimp (Penaeus monodon)

The effects of methanolic extracts of two terrestrial herbs Withania somnifera (WS) and Mucuna pruriens (MP) enriched Artemia supplementation (5% of the spawner’s body weight/day) over the reproductive performance, biochemical parameters and larval quality indices in the spent spawners of Penaeus monodon were investigated. Among the three groups, MP fed group registered higher values in the reproductive performance like fecundity and frequency of spawning than the control group (P<0.05). The offspring quality in terms of egg size, fertilization rate, cumulative metamorphosis, cumulative larval survival and reduced larval abnormalities were significantly influenced by the WS supplementation when compared to the control (P<0.05). Total Protein and lipid levels were significantly higher in the WS fed group values than the control (P<0.05). WS supplementation also significantly influenced the hatching percentage, reduced larval abnormalities, cumulative metamorphosis, cumulative larval survival, haemolymph protein and lipid level than the control group (P<0.05). Both MP and WS have the potential to improve the performance of fecundity and larval quality in multiple spawning during the forced reproduction in the tiger shrimp.

Several new models of discrete rec- ognition procedures are described alongside new approaches to the search for informative fragments in feature descriptions of objects. The metric (quantitative) properties of elementary classifiers are examined.
Active Shape Models on adaptively refined mouth emphasizing color images

In this paper, we propose a hybrid method for lip segmentation based on normalized green-color histogram splitting and Active Shape Models (ASM). A new adaptive method for histogram splitting is applied in two steps. First, after defining a region of interest for mouth segmentation, a rough adaptive threshold selects a histogram region assuring that all pixels in that region are skin pixels. Second, based on these pixels, we build a Gaussian model which represents the skin pixels distribution and is used to obtain a refined optimal threshold for lip pixel classification. This process is used to refine the normalized green channel image for the elimination of inner distortions and gradients inside the lip region, which can misguide active contours (i.e. ASM) in the last step of the hybrid segmentation process. In the results, we present that the proposed method performed better than conventional ASM on unrefined color enhanced images or pure color-histogram based mouth segmentation.

Description of API elements that is Methods, Classes, Constructors etc. is provided through API Reference Documentation. Hence API Reference Documentation acts as a guide to user or developer to use API’s. Different types of Knowledge Types are generated by processing this API Reference Documentation. And this Knowledge Types will be used for Classification and Searching of Java API Reference Documentation.
Comparative Study Between Partially and Fully Recessed‐Gate Enhancement‐Mode AlGaN/GaN MIS HEMT on the Breakdown Mechanism

In this paper, two enhancement‐mode (E‐mode) AlGaN/GaN recessed‐gate MIS devices with the in situ N2 plasma treatment, known as partially recessed‐gate metal insulator semiconductor (MIS) device and fully recessed‐gate MIS device, are designed. Among them, the partially recessed‐gate MIS device shows excellent characteristics that the threshold voltage of +3.5 V, saturation current density of 722 mA mm−1, peak transconductance of 212 mS mm−1, and the power figure of merit of 4.39 × 108 W cm−2 which is the highest value in E‐mode AlGaN/GaN MIS device with the threshold voltage greater than 3 V. Moreover, the current collapse and breakdown voltage of partially recessed‐gate MIS device and fully recessed‐gate MIS device are investigated, and Silvaco simulation is carried out to analyze the difference of breakdown mechanism between two structure devices. Through the analysis of five main breakdown leakage paths, we can get the conclusion that the factor causing the breakdown voltage difference between partially recessed‐gate MIS device and fully recessed‐gate MIS device is the difference in the width of depletion region of the two devices.
Lagrangian Dispersion Characteristics in The Western Mediterranean

Dispersion characteristics in the Western Mediterranean are analyzed using data from Coastal Ocean Dynamics Experiment (CODE) and Surface Velocity Program (SVP) surface drifters deployed in the period 1986–2017. Results are presented in terms of absolute dispersion A2 (mean-squared displacement of drifter individuals) and of relative dispersion (D2; mean square separation distance of drifter pairs). Moreover, the dispersion characteristics are estimated for different initial separation distances (D0) between particles: smaller, larger, or comparable with the internal Rossby radius of deformation. Results show the presence of a quasiballistic regime for absolute dispersion at small time scales and the nonlocal relative dispersion regime related to the submesoscale activities for scales smaller than the internal Rossby radius. At intermediate times, two anomalous absolute dispersion regimes (elliptic and hyperbolic regimes) related with the flow topology are observed, although the relative dispersion involves the Richardson and shear/ballistic regimes only for D0 smaller than the Rossby radius. During the subsequent 20–30 days, absolute dispersion shows quasirandom walk regime and relative dispersion follows the diffusive regime for scales larger than 100 km for which pair velocities are uncorrelated.
Authentic computer science undergraduate research experience through computational science and research ownership

Research experience has been identified as a high-impact intervention for increasing student engagement and retention in STEM. However, authentic undergraduate research leading to primary authorship peer-reviewed publications is a challenge due to the relatively short time the students work on their capstone projects, and the insufficient preparation of the students as researchers. The challenge is further magnified in the field of computer science, where the absence of “traditional” labs limits the opportunities of undergraduate students to participate in research. Here we present a novel approach to authentic computer science undergraduate research, based on interdisciplinary computational science and student ownership of their research projects. Instead of the traditional role of undergraduate research assistant, the students select their own research topic based on their personal interests, and with the assistance of a faculty complete all stages of their research project. The uniqueness of the approach is its ability to lead to scientific discoveries and peer-reviewed publications such that the primary author is the student, while allowing the student to experience the entire research process, from defining the research question through analysis of the experimental results. In three years the model led to a dramatic increase in the number of undergraduate students who publish primary-author peer-reviewed scientific papers. The intervention increased the number of peer-reviewed student-authored publications from none to a very high rate of about one third of the students, in many cases publishing in the top outlets in their
FEA and Multivariate Statistical Data Analysis of Polypropylene Tube Forming Process

In present, the automotive and aircraft industries, give a lot of attention to plastic materials due to the advantages of light weight, low cost, and extra strength. Although the metal gas forming is a well‐known process, the plastic tube forming is a quite new area of research. In this paper, the FEA of the tube forming process of polypropylene tube with different material properties and process parameters and the following multivariate statistical data analysis is presented. The FEA is performed with implementation of axisymmetrical model in Abaqus Explicit. The quality of the final product is introduced as a tube wall thickness distribution along the length of the tube. The product quality dependence on the material properties and process parameters will be illustrated in this research. Also a technique of the optimal tube wall thickness distribution is proposed. This technique allows to adjust the manipulated variables trajectories, such as temperature, strain rate, internal pressure and axial displac.
Repositioning Strategy for Malaysian Companies Internationalization

1024x768 The rise of the emerging-market countries offers both developing and developed countries a unique opportunity to gain the benefits of a truly international economy. Consequently, it is imperative to advance our knowledge of emerging-market countries MNC emergence and competitiveness including Malaysian firms on how will they position their products strategically? Based on the framework of Porter’s Generic Strategy this paper is composed of price/ volume segments and impacts on product strategy theory. The aim is to identify crucial triggering cues and focus areas for Malaysian companies and measure what role these play in different segments. This study argues that some Malaysian companies will reposition themselves strategically when internationalizing and that they will focus on other factors or triggering cues when doing so not merely adapting the prevalent price leadership strategy.

Galectin signatures contribute to the heterogeneity of breast cancer and provide new prognostic information and therapeutic targets

Because of their ability to induce local immunosuppression and to confer cancer cells with resistance to apoptosis, members of the galectin family are emerging as a new class of actionable targets in cancer. Unfortunately, we have yet to obtain a clear picture of the galectin signatures in cancer cells and the surrounding tumor microenvironment. The aim of this study was to provide the first detailed analysis of the galectin signature in molecular subtypes of breast cancer. Expression signatures of galectins were obtained at the mRNA and protein levels. A particular attention was paid to stromal versus epithelial staining and to subcellular compartmentalization. Analysis of the stromal signature showed that gal-1, -3, -9-positive stroma were preferentially found in triple-negative (TN) and HER2 subtypes. In cancer cells, gal-1, -3, -8, and -9 showed a dual expression pattern, being found either in the cytosol or in the cytosol and the nucleus. TN patients with gal-8-positive nuclei had significantly better disease-free survival (DFS), distant-disease-free survival (DDFS), and overall survival (OS). In contrast, high expression of nuclear gal-1 correlated with poor DDFS and OS. TNBC patients who were positive for both nuclear gal-1 and gal-8 had 5-year DFS and DDFS of 100%, suggesting a dominance of the gal-8 phenotype. Overall, the results indicate that specific galectin expression signatures contribute to the phenotypic heterogeneity of aggressive subtypes of breast cancer. Our data also suggest that galectins have clinical utility as indicators of disease progression and therapeutic targets in aggressive molecular subtypes of breast cancer.
SCREENING AND CHARACTERIZATION OF L-GLUTAMINASE PRODUCED BY BACTERIA ISOLATED FROM SANGIHE TALAUD SEA

L-glutaminase (L-glutamine amidohydrolase, EC 3.5.1.2) is a very important enzyme due to its role as flavor enhancer and antileukemic agent. Salt-tolerant L-glutaminase produced by marine bacteria is favorable in food industries. This study describes the screening of L- glutaminase producing marine bacteria from Sangihe-Talaud Sea, North Sulawesi, Indonesia. Screening of L-glutaminase was performed using a liquid medium and identification of selected isolate was performed using molecular-based 16S rDNA. Results showed that there were 7 isolates produced positive results of L-glutaminase, and one of them (II.1 isolate) produced the highest activity, i.e 147.99 U/L, equivalent to the specific activity of 62.32 U/mg. The isolate then selected for further study. Bacterial identification based on 16S rRNA sequencing has revealed that the isolate was 96% similar to Pseudomonas aeruginosa strain CG-T8. Characterization of extracellular L-glutaminase from the II.1 isolate showed that the enzyme worked optimally at temperature of 37-45 °C and pH 7. The enzyme was stable when NaCl solution was added up to 8% and began to decrease on addition of NaCl solution of 16% and 20% with relative activity of 79% and 74%, respectively. The effect of metal ions, e.g Mn2+, Mg2+, and Co2+ in the form of chloride salt, were able to increase enzyme activity, whereas the addition of other metal ions (Zn2+, Fe3+, and Ca2+) decreased the activity. The molecular weights of L-glutaminase was estimated around 42 kDa and 145 kDa.
Investigation of chevron synthetic jets flow field and heat transfer

The present thesis analyses the effect of a saw-tooth exit pattern, called chevron exit, on the flow field and heat transfer of a synthetic jet. The chevron exits are generally applied at the trailing edge of jet engine nozzles for acoustic noise reduction and mixing enhancement. For the present study, the synthetic jet is obtained by a loudspeaker as oscillating element and a contoured nozzle as inlet/outlet aperture. Two experimental techniques are used: Stereoscopic Particle Image Velocimetry for the two-dimensional three-component flow field measurements and Infrared thermography in conjunction with the heated thin foil heat transfer sensor for the heat transfer measurements. Owing to the peculiar features of synthetic jets and the effect of the chevron elements on the coherent structures organisation, the chevron exit could lead to a heat transfer enhancement. It is shown that this kind of nozzle can produce an increase of turbulence intensity levels in some regions of the field and entrainment and mixing enhancement by introducing streamwise coherent structures.
Assessment of ECMWF reanalysis data in complex terrain: Can the CERA‐20C and ERA‐Interim data sets replicate the variation in surface air temperatures over Sichuan, China?

Surface air temperatures (SATs) derived from the European Centre for Medium‐Range Weather Forecasts (ECMWF) ERA‐Interim and CERA‐20C reanalysis data sets are compared with data from 43 observation stations in Sichuan for 1979–2010. The results show (a) the temperatures from the ERA‐Interim and CERA‐20C data sets are strongly correlated with those from the observation stations, although significant cold biases are seen on both annual and seasonal timescales. (b) The biases in SATs are predominately influenced by the differences between the actual topography and the topography used in the reanalysis models. Larger differences in temperature are observed in the plateau and mountainous regions of Sichuan. We confirmed larger SAT biases at high altitudes by categorizing the elevation into four bands, each with a spacing of 1,000 m. (c) We reduced the biases resulting from elevation by using an elevation correction method with internal lapse rates derived from different reanalysis pressure levels. The annual mean bias was reduced from −2.86 to −0.75°C for the ERA‐Interim data set and from −5.27 to −2.21°C for the CERA‐20C data set. After calibration, the correlation coefficients between the difference in SAT (observed minus reanalysis data) and the difference in elevation (station elevation minus model elevation) decreased from −0.97 and −0.91 to −0.29 and −0.30 for the ERA‐Interim and CERA‐20C data sets, respectively. These significant differences should not be ignored in the application of reanalysis data sets to climate research. The evaluation and calibration of reanalysis data sets are essential before making assessments of regional climate change, especially over regions with complex topography.
A Comparison of Redundancy Techniques for Private and Hybrid Cloud Storage

File redundancy techniques have been very useful mechanisms for offering fault tolerance and data availability in anykind of storage. Cloud storage is not the exception. This paper presents an evaluation of classical file redundancytechniques implemented in two cloud-storage deployment models, private and hybrid. A small prototype of a privateand hybrid cloud storage was implemented for this evaluation. The performance impact when file redundancy is onlyapplied in a private cloud versus when redundancy is also distributed in a public cloud (the hybrid model) is analyzed.Additional to classical file redundancy techniques, an innovative method was evaluated for file redundancy based onan information dispersal algorithm (IDA). The usage of IDA represents a good option for managing sensitive data inhybrid cloud storage. In this technique, only parts of a file need to be sent to the public cloud, avoiding the completefile to be read from outside of the private zone. In this context, there is a trade-off between performance (forreconstructing the original file, it is first necessary to obtain all of its fragments) and the security level that coulddetermine the viability of using IDA.
Estimation of Cost Efficiency of Dairy Farms in Kenya’s Eastern Central Highlands

The objective of this study was to determine the cost efficiency of dairy cow farms in the Eastern Central highlands of Kenya. The data was collected through a cross-sectional survey from 135 farms in the study region. The sample size was determined using the Fischer’s formula. A stochastic frontier cost function was estimated using the maximum likelihood estimation technique. The MLE results revealed that the costs of roughages and labour were the major determinants of dairy farming cost. The farms operated at low economies of scale, mainly because the land size owned averaged only two acres; where mixed crop-livestock farming was practiced. It was revealed that roughages could substitute with either mineral supplements or labour to reduce farming costs. The mean farms cost efficiency index was 4.4% above the frontier cost. Most farms did not make profits. The average cost per farm was Ksh. 551 while the milk revenue was Ksh.365. It was concluded that farmer-cost inefficiency was not the main cause of the high milk production cost. The cost of feeds coupled with the relatively small land sizes owned and the cost of labour were the main challenges facing dairy farming in the study region. It was recommended that policy makers come up with necessary laws and regulations to ensure that the continued land sub-division is reversed and that the cost of dairy farming inputs is reduced. Researchers require establishing the least-cost combination ratio for roughage and labour.
The biocenotic values of Slitere National Park, Latvia: With special reference to inter-dune mires

Inter-dune wetlands in Europe harbour many Red List species because they are very nutrient-poor ecosystems. Most of these wetlands are geologically very young and no or little peat formation has occurred. In Slitere National Park the numerous inter-dune wetlands are relatively old, up to 4500 years old, and most mire communities are peat forming and they are well preserved. However, the hydrological systems that have conserved the mires are largely unknown. In the present study we analysed 128 vegetation relevees of dune mires in order to assess the variation in ecological mire types. We also carried out several short-time studies to get an insight into the peat development and hydrological conditions that sustain the mires. We describe peat profiles and measured temperature profiles and electrical conductivity in 26 dune valleys. We distinguished three main vegetation units and ten sub-units, representing various stages in peat formation. Based on electrical conductivity and temperature profiles we hypothesised that the mires were sustained by both local and more regional groundwater flows, of which the latter were possibly disturbed by anthropogenic influences, mainly outside the National Park. The importance of the Park was evaluated by comparing it to species lists of wetlands from all countries bordering the Baltic Sea. On the European scale the inter-dune wetlands of Slitere National Park are very important because they represent well-developed examples of mire formation on a landscape scale, which elsewhere in most of Europe are rare or have become extinct due to intensive land use.
Inspecting Mixed-Ability Group Challenges within Iranian EFL Public High Schools: An Exploratory Study Fatemeh

The nature of heterogeneity issues within the context of Iranian, English language learning contexts in high schools is one of the under-researched lines of inquiry. For this aim, a researcher-made, Likert-type questionnaire whose items were initially validated through a multistage, exploratory research design among 30 teachers was distributed among some 67, Iranian EFL teachers with different degrees of experience (less vs. more) to find the teachers’ concerns/challenges and their strategies to tackle them. The findings suggested that the concerns behind heterogeneous classes were not consistent regrading weak and strong students. In the second place, it became evident that the order of tendency towards adopting the four enunciated strategies was not the same in the two less and more experienced teachers. Possible interpretations regarding teacher outlook as mapped on ‘teacher experience’ to target heterogeneity issues were presented in the end.
