Enhanced Bandwidth Characteristics of Multiwall Carbon Nanotube Microstrip Patch Antenna at

In this paper we report the preliminary investigation on the novel Multi walled Carbon Nano Tube (MWCNT) based composites for Microstrip patch antenna design. The MWCNT based nano composite layer with two configurations viz., PAni – pTsA with MWCNT (Polyaniline–para-Toluene Sulfonic acid with MWCNT) and PAni –NSA with MWCNT (polyaniline – Naphthalene Sulfonic acid with MWCNT) above the conventional copper patch antenna was designed and studied using High Frequency Structure Simulator software (HFSS) in the X – band of frequencies. The simulation results revealed that the Nano composite based antenna exhibits an excellent antenna characteristic with stable Gain and radiation pattern around 9.5 GHz to 10.5 GHz frequency range by using inset feed configuration. MWCNT based nano composite antenna is simulated and the performance is compared with a conventional patch antenna. The results shows that, insertion of MWCNT nano composite layer over the microstrip patch antenna increases its operation bandwidth up to 3.12% without considerable degradation in other parameters. The proposed MWCNT nano composite antenna is finds application for stealth aircrafts.
Sequestering Nickel (II) Ions from Aqueous Solutions Using Various Adsorbents: A Review

Adsorption process has proven to be one of the best water treatment technologies around the world and activated carbon is undoubtedly considered as a universal adsorbent for the removal of different types of pollutants from water. However, widespread use of commercial activated carbon is sometimes restricted due to its high cost. Attempts have been made to develop inexpensive adsorbents utilizing numerous agro-industrial and municipal waste materials. Use of agricultural waste materials as low-cost adsorbents is attractive because it reduces the cost of waste disposal, thereby leading to environmental protection. In this review, agricultural, synthetic and other adsorbents used for adsorbing nickel (II) ion from aqueous solutions are reported. Different ways to improve their efficiencies are also discussed.
A Survey on Exploiting Service Similarity Based on Location Privacy

: Location based applications exploits the focusing capabilities of mobile device to determine the current position of user, and specifies the query results to capture the neighboring points of interest. As Location knowledge is truly recognized as personal information, One of the immediate issues hampering the wide reception of location-based applications is the defect of appropriate methodologies that gives grain privacy controls to user without affecting the usability of service. In this paper the propose system is an innovative approach that simultaneously ensures both the privacy and the integrity. This is achieved by using space encryption as the basis of our approach and then devising techniques that enable the data users to audit the integrity of the query result for the most important spatial query types: range queries and k -nearest-neighbor queries (k NN). And it can be done by using the MR-tree, an index based on the R*-tree, capable of authenticating arbitrary spatial queries. We can show, analytically and experimentally, that the MR-tree is considerably faster to build and consumes less space. The MR-tree combines concepts from MB and R*-trees.
Real-time depth map occlusion filling and scene background restoration for projected-pattern based depth cameras

In this paper we present our approach to real-time filtering of depth maps taken using projected-pattern-based depth cameras and to restoration of scene backgrounds for images taken using aligned RGB and depth cameras. An original depth map contains a numerous occlusions, and stereo-from-depthmap video generation leaves many uncovered areas. To solve this problem we propose an adaptive occlusion-filling algorithm for depth map processing and for restoration of scene backgrounds using depth map. Our goal is to accurately fill occlusions while maintaining real-time processing speed using common workstations.
Simulation benchmarks for low-pressure plasmas: Capacitive discharges

Benchmarking is generally accepted as an important element in demonstrating the correctness of computer simulations. In the modern sense, a benchmark is a computer simulation result that has evidence of correctness, is accompanied by estimates of relevant errors, and which can thus be used as a basis for judging the accuracy and efficiency of other codes. In this paper, we present four benchmark cases related to capacitively coupled discharges. These benchmarks prescribe all relevant physical and numerical parameters. We have simulated the benchmark conditions using five independently developed particle-in-cell codes. We show that the results of these simulations are statistically indistinguishable, within bounds of uncertainty that we define. We, therefore, claim that the results of these simulations represent strong benchmarks, which can be used as a basis for evaluating the accuracy of other codes. These other codes could include other approaches than particle-in-cell simulations, where benchmarking could examine not just implementation accuracy and efficiency, but also the fidelity of different physical models, such as moment or hybrid models. We discuss an example of this kind in the Appendix. Of course, the methodology that we have developed can also be readily extended to a suite of benchmarks with coverage of a wider range of physical and chemical phenomena.
Fault tolerant longitudinal aircraft control using non-linear integral sliding mode

This study proposes a novel non-linear fault tolerant scheme for longitudinal control of an aircraft system, comprising an integral sliding mode control allocation scheme and a backstepping structure. In fault free conditions, the closed loop system is governed by the backstepping controller and the integral sliding mode control allocation scheme only influences the performance if faults/failures occur in the primary control surfaces. In this situation, the allocation scheme redistributes the control signals to the secondary control surfaces and the scheme is able to tolerate total failures in the primary actuator. A backstepping scheme taken from the existing literature is designed for flight path angle tracking (based on the non-linear equations of motion) and this is used as the underlying baseline controller in nominal conditions. The efficacy of the scheme is demonstrated using a high-fidelity aircraft benchmark model. Excellent results are obtained in the presence of plant/model uncertainty in both fault free and faulty conditions.
A Participatory Method for Multidimensional Analysis and Proposing Improvements in Collaborative Systems

The difficulty of evaluating collaborative systems is a historical challenge, since the multiple dimensions of collaboration are considered success factors for the system, and these factors go beyond individual interaction. Adopting the fundamentals of Participatory Design, this paper presents a multidimensional method for evaluating and proposing improvements on collaborative systems. The method involves three phases: (1) a presential briefing phase; (2) a non-presential observation phase; and (3) a Future Workshop phase. Instances of the proposed method seek to involve users as co-designers, making informed and relevant decisions about the future of a system which they could learn and use. This paper also presents the results of a preliminary evaluation, which consists in an instance of the method: evaluating and proposing improvements on a groupware prototype. The instance is compared to a traditional groupware evaluation method, exposing that the instance, not only identified similar collaboration-related issues, but also identified issues that were not identified by the inspection. During the experiment, participants informed us about issues experienced while collaborating and how they were perceived, and elicited possible futures in which the system would have more value to their objectives.
The Interplay of Well-being and Resilience in Applying a Social-Ecological Perspective

Innovative combinations of social and ecological theory are required to deal with complexity and change in human- ecological systems. We examined the interplay and complementarities that emerge by linking resilience and social well-being approaches. First, we reflected on the limitations of applying ecological resilience concepts to social systems from the perspective of social theory, and particularly, the concept of well-being. Second, we examined the interplay of resilience and well-being concepts in fostering a social-ecological perspective that promises more appropriate management and policy actions. We examined five key points of interplay: (1) the limits of optimization thinking (e.g., maximum sustainable yield), (2) the role of human agency and values, (3) understandings of scale, (4) insights on "controlling variables," and (5) perspectives on thresholds and boundaries. Based on this synthesis, we offer insights to move incrementally towards interdisciplinary research and governance for complex social-ecological systems.
Modified Long Short-Term Memory Recurrent Neural Network Architectures

: Long Short-Term Memory (LSTM) is a specific recurrent neural network (RNN) architecture that was designed to model temporal sequences and their long-range dependencies more accurately than conventional RNNs. In this paper, we explore LSTM RNN architectures and made some changes for its better performance. LSTM RNNs are more effective than DNNs. Here, we have changed the gates calculation and also have removed some unnecessary features of standard LSTM architecture. This architecture makes more effective use of model parameters than the others considered, converges quickly, and outperforms a deep feed forward neural network having an order of magnitude more parameters.
Analysis of the Difference in Landing Between Male and Female High School Soccer Athletes

Introduction: Females are consistently found to be at a higher risk of tearing their ACL. Extensive research has been completed previously to determine what causes an ACL tear and why this separation exists but a confirmed conclusion has not been found. Potential extrinsic factors such as decreased knee flexion and increased valgus have commonly been suggested as increased stressors on the ACL. The focus of this study is to determine if there is a significant difference in these two factors between males and females. Methods: Seven healthy and highly trained subjects between the ages of 17 and 18 who do not have a history of anterior cruciate ligament injury. Three trials of the subject stepping off a 63.5 centimeter bleacher and landing naturally. Frontal and sagittal plane filmed. One trial chosen to be digitized and analyzed with MaxTRAQ software. Specifically, knee flexion and valgus angles were measured with the software at initial contact of the landing and for maximum angle. Results: Females landed with more knee flexion at initial contact and more valgus at initial contact. Maximum knee flexion angles were only slightly different. When comparing maximum valgus, females exhibited more than males. Significant difference was not found among males and females for knee flexion. Female valgus angles were found to be significantly different than male valgus angles. Discussion: Results comparable with current research pertaining to valgus data. Knee flexion results differ. Important for understanding ACL risk of future athletes and the potential for training interventions. Conclusion: Original hypothesis found to be incorrect. Only a significant difference in valgus angle was found. Additional research with more subjects is needed to determine accuracy of results.
USING LARVAL TREMATODES THAT PARASITIZE SNAILS TO EVALUATE A SALTMARSH RESTORATION PROJECT

We conducted a Before-After-Control-Impact (BACI) study using larval digeneans infecting the California horn snail, Cerithidea californica, to evaluate the success of an ecological restoration project at Carpinteria Salt Marsh in California, USA. Digenean trematodes are parasites with complex life cycles requiring birds and other vertebrates as final hosts. We tested two hypotheses for prevalence and species richness of larval trematodes in C. californica: (1) prior to the restoration, sites to be restored would have lower trematode prevalence and species richness relative to unimpacted control sites, and (2) that these differences would diminish after restoration. The sites to be restored were initially degraded for trematode species. They had a mean trematode prevalence (12%) and species richness (4.5 species) that were lower than control sites (28% trematode prevalence and 7 species). Despite the differences in prevalence, the proportional representation of each trematode species in the total community.
Reduction in nitrogen fertilizer applications by the use of polymer-coated urea: effect on maize yields and environmental impacts of nitrogen losses.

BACKGROUND Urea is commonly over-applied as a nitrogen (N) fertilizer to crops in southern China and has a low utilization efficiency as a result of the high precipitation and high temperatures in this region. This has led to a need to optimize the management of N fertilizer use in maize crops on the subtropical hilly uplands of southern China. RESULTS We investigated the effects of applying different amounts of N in the form of polymer-coated urea (PCU) on the yield of maize and gaseous losses of N from soils in the form of NH3 and N2 O. The field plots used in this trial had zero-added N (0 kg N ha-1 ), the addition of urea (240 kg N ha-1 ) and four levels of fertilization with PCU (1 PCU, 0.9 PCU, 0.8 PCU and 0.7 PCU), which represented a 0%, 10%, 20% and 30% reduction, respectively, in the application of PCU-N relative to the urea plot. Compared to the urea plot, there was little variation in the yield of maize for all the PCU-N treatments, with a significant improvement in the utilization efficiency of N (up to 46.0-51.2%) with a 0-30% reduction in the application of PCU-N. Significant effects in the mitigation of the N2 O emission flux and the accumulation of N2 O-N were observed in the 0.8 PCU and 0.7 PCU plots. The application of PCU-N significantly reduced the flux and total amount of NH3 -N lost to the environment: as the application rate for N decreased by 0-30%, the NH3 loss was significantly reduced by 12.7-36.1%. CONCLUSION The findings of the present study suggest that the use of PCU could allow a reduction in the application of N of 20-30% compared to traditional agricultural practices in this area with the same yield of maize, although with significantly decreased NH3 and N2 O losses and the increased utilization of N. © 2018 Society of Chemical Industry.
Congestion Control Techniques in Programmable Computer Networks

: Software Defined Networking (SDN) is becoming an apparent network architecture where network control is separated from data plane which is directly programmable. It promises to remove the complexity of the network management and enable upheaval through network programmability. The POX is one of the open source Software Defined Network controller and a platform for the expeditious development and designing of network control software. This paper defines the difference between various parameter when calculated for traditional network and SDN network and proposes a set of rules which are defined in the POX controller as the controller component and based on which the open flow switch will take the decisions during transmission of data packets in the Open flow network. This method proposed to increase the performance of the network by avoiding congestion using spanning tree protocol which reroutes the packet in case of link failure/congestion. This paper also described the process of defining different set of rules in each switch in the network. The experimental results shows average round trip time(RTT) or average delay for network with and without congestion/link failure detection for POX controller. Along with the comparison between traditional and SDN network based on various parameters.
Effect of Microwave Treatment and Digestive Enzymes on Cereal Water-Retention Capacity

Different hydration characteristics of dietary fibers are related to their chemical structure. Processing conditions can modify the physical properties of the fiber matrix and consequently affect their hydration properties. Microwave treatment of cereals and legumes is able to increase the water retention capacity (WRC), which often is required in baked products to make the texture harder and crispy. The present study investigated the effect of microwave radiations on WRC of wheat and barley submitted to in vitro simulated digestion. A slightly higher WRC was observed in treated wheat, from 0.96 g water/g DM (untreated) to 1.015 g water/g DM (treated for 30 s). Greater WRC values were recorded in barley, due to the higher β-glucan content: from 1.026 g water/g DM (untreated) to 1.361 g water/g DM (treated for 30 s).
Work Representation and Union Representativeness on the Frontier of Wage Earning

Representation du travail et representativite syndicale aux marges du salariat : le cas de la distribution directe La reforme de la representativite syndicale permet-elle de lutter contre l’institutionnalisation des syndicats ? L’article s’interroge sur cette attente, qui se retrouve autant chez les acteurs de la reforme que chez les specialistes du syndicalisme. En etudiant un secteur professionnel de constitution recente, la distribution directe, il montre que la reforme ne saurait repondre a un probleme incorrectement formule. L’institutionnalisation des syndicats est en effet un processus contradictoire, qui dissocie autant qu’il relie les salaries a leurs representants. Cette precision conduit a etudier l’impact de la reforme de la representativite syndicale de maniere plus nuancee. La mobilisation des regles de representativite dans les deux entreprises etudiees montre que les effets de la reforme en termes de syndicalisation s’averent ambivalents. Le nouveau regime de representativite ne garantit pas davantage un controle plus etroit des salaries sur leurs representants. Il accroit en revanche l’interdependance des arenes de branche et d’entreprise, en tant que celle-la est desormais connectee a celles-ci via la procedure elective.
CRISPR‐PLANT v2: an online resource for highly specific guide RNA spacers based on improved off‐target analysis

Since the beginning of CRISPR/Cas9's use for genome-editing, reports of off-targets have caused concerns among users. Previous studies identified three main types of off-targets. The first type of off-targets are sequences at other 5'-NGG-3' protospacer adjacent motifs (PAMs) that are identical or have a small number of mismatches or substitutions (Fu et al., 2013; Tsai et al., 2015). The second type of off-targets are sequences at other 5'-NGG-3' PAMs that have insertions or deletions compared to the gRNA spacer or the targeted DNA (Lin et al., 2014).

BIOACTIVE POTENTIAL OF ENDOPHYTIC FUNGI ASPERGILLUS FLAVUS (SS03) AGAINST CLINICAL ISOLATES

Objective: This study was to evaluate the antimicrobial potential of endophytic fungi isolated from the medicinal plant Moringa oleifera Lam. collected from the Omalur region, Salem district. Methods: The endophytic fungi were isolated from stem, leaves, flowers and calyx of Moringa oleifera by surface sterilization method. The samples were surface sterilized by immersing it in 70% ethanol for 5 seconds followed by 4% sodium hypochlorite for 90 seconds and then a final rinsing in sterile distilled water. Then fungal biomass was extracted for intracellular metabolites by using ethyl acetate as solvent. The crude extract was filtered, and the filtrate was dried under vacuum at 40 °C. The filtrate was analyzed for antimicrobial activity. The fungi which showed the maximum activity was identified and the metabolite present in the ethyl acetate extract was characterized and identified by GC-MS and NMR analysis. Results: The predominant endophytic fungi isolated belongs to the genera of Aspergillus spp, Aspergillus flavus, Aspergillus versicolor, Aspergillus niger, Aspergillus ochraceus, Aspergillus terreus and dematiaceous fungi namely Bipolaris spp. From this Aspergillus flavus showed the highest zone of inhibition was observed against Staphylococcus aureus and Bacillus 22 mm and strain of Candida tropicalis 19 mm. The efficiency of the bioactive compound was identified by GC-MS and NMR analysis and found to be Fenaclon, (R)(-) 14 methyl-8-hexadecyn-1-ol, Trans-β-farnesene (E)-β-farnesene, 9-Octcadecene,1,1, Dimethoxy Conclusion: This study results indicate that the bioactive metabolites produce the endophytic fungi Aspergillus flavus could be promising source as antimicrobial agents.
A Lactobacillus Cocktail Changes Gut Flora and Reduces Cholesterolemia and Weight Gain in Hyperlipidemia Mice

We have developed a hyperlipidemia mouse model system to test the effects of natural Lactobacillus bio-products on intestinal microflora, organ physiology and lipid metabolism. Using denaturing gradient gel electrophoresis, PCR, quantitative real-time PCR and Southern blots, we show that Lactobacillus has different effects on the intestinal microflora compared to pharmaceutical drugs such as Simvastatin. The pool treated with Lactobacillus (L. plantarum, L. acidophilus and L. casei) is found to be closer than the control conditions. We report the existence of twelve main gut bacterial strains related to lipid metabolism in mice (Bacillus amyloliquefaciens, B. licheniformis, B. oleronius, Enterobacter sp. dc6, Enterococcus faecium, Lactobacillus johnsonii, Lactococcus sp. M3T8B4 and four uncultured bacteria); most of which are found to be regulated by the cocktail of lactobacilli. In addition, we show that treatments with the three lactobacilli significantly reduce body weight, LDL and specific tissue fat pad levels, and increase HDL in experimental hyperlipidemic mice. Most importantly, addition of the Lactobacillus cocktail to fat food diet is found to keep gut flora normal and to prevent not only high blood lipid concentration but also cholesterolemia and weight gain. On the basis of these results we propose the use of L. plantarum, L. acidophilus and L. casei in a bio-product cocktail not only as a food complement to regulate the gut flora and prevent lipid accumulation but also as an alternate therapy to pharmaceutical drugs for the treatment of hyperlipidemia, obesity and all other genetic disorders that cause severe deficiency in lipid metabolic pathways.
Survey on Hybrid Approach for Feature Selection

: In text document categorization, feature selection (FS) is a strategy that aims at making text document classifiers more efficient and accurate. However, when dealing with a new task, it is still difficult to quickly select a suitable one from various FS methods provided by many previous studies. Feature selection, as a preprocessing step to machine learning, has been very effective in reducing dimensionality, removing irrelevant data, and noise from data to improving result comprehensibility. Researchers have introduced many feature selection algorithms with different selection criteria. However, it has been discovered that no single criterion is best for all applications. We proposed a hybrid approach for feature selection called based on genetic algorithms (GAs) that employs a target learning algorithm to evaluate features, a wrapper method. The advantages of this approach include the ability to accommodate multiple feature selection criteria and find small subsets of features that perform well for the target algorithm. In this way, heterogeneous documents are summarized and presented in a uniform manner.
