Designing of an antenna using Proximity coupled feed for 4 G applications

In this paper a rectangular Microstrip patch antenna is designed for proximity coupled feeding technique for wireless microstrip patch antenna i.e 4G applications. In this paper the antenna is resonating at 2.2 GHz frequency range which is desired frequency for IMT-advance (4G) range. The frequency range for 4G is vary from 1710 MHz to 2690 MHz . The proposed antenna is designed by using rectangular type patch for particular feeding technique (proximity coupled feed) is used. From the four feeding techniques, microstrip line and coaxial probe feeds are contacting schemes whereas proximity and aperture coupled feed are non-contacting schemes. The Paper gives a better understanding of design parameters of an antenna and their effect on return loss, SParameters, smith chart, radiation pattern, bandwidth, VSWR and resonant frequency. Finally simulation is done using design software HFSS. Keywords— Rectangular microstrip patch antenna, S-Parameters, smith chart, radiation pattern, bandwidth, VSWR, resonant frequency, proximity coupled feed, HFSS.
DYNAMICS MODELING AND ROBUST CONTROLLER DESIGN OF THE MULTI-UAV TRANSPORTATION SYSTEM

This paper presents the design process of cooperative transportation system with multiple unmanned aerial vehicles connected with strings. Moving pendulum dynamics is modeled with Newtonian approach via combination of 3dimensional Cartesian coordinates and spherical coordinates. The modeled system is controlled linear quadratic Gaussian / loop transfer recovery method. Furthermore, system parameter variations are compensated with parameter-robust linear quadratic Gaussian method. The numerical result of the both controls is compared to show improvements in parameter robustness.
zospirillum inoculation effects on growth , product quality and torage life of lettuce plants grown under salt stress

Recent results have shown that Azospirillum-inoculated lettuce seeds yield a higher number of transplanted plants with superior traits than non-inoculated controls grown with and without saline stress. However, little available information on the possibility that Azospirillum could improve nutritional and quality market parameters on plants grown under saline conditions and extend life storage has prompted us to explore this issue. In this work, seed inoculation with Azospirillum not only promoted higher biomass but also improved lettuce quality when plants were grown under salt-stress conditions. Compared to non-inoculated controls, higher ascorbic acid content was accompanied by a lower oxidation rate in Azospirillum-inoculated plants. In addition, better overall visual quality was linked to higher chlorophyll content, hue, Chroma, L and lower browning intensity. While the beneficial effects of Azospirillum inoculation were more evident at harvest, some of these continued thereafter. Compared to non-inoculated
M ay 2 01 9 Local Density Fluctuation Governs Divergence of Viscosity underlying Elastic and Hydrodynamic Anomalies in 2 D Glass-Forming Liquid

If a liquid is cooled rapidly to form a glass, its structural relaxation becomes retarded, producing a drastic increase in viscosity. In two dimensions, strong long-wavelength fluctuations persist, even at low temperature, making it difficult to evaluate the microscopic structural relaxation time. This Letter shows that, in a 2D glass-forming liquid, relative displacement between neighbor particles yields a relaxation time that grows in proportion to the viscosity. In addition to thermal elastic vibrations, hydrodynamic fluctuations are found to affect the long-wavelength dynamics, yielding a logarithmically diverging diffusivity in the long-time limit.
Vortex merging in quasi-geostrophic flows

We study symmetric vortex merger in quasi-geostrophic flows using numerical simulations with high vertical resolution. We analyse the effect of varying the vertical aspect ratio of the vortices and compare with the barotropic case. During the merging of potential vorticity cores with small aspect ratio, we observe the birth of secondary instabilities on the filaments. This is a new phenomenon not seen in baroclinic simulations having low vertical resolution. Passive Lagrangian tracers are used to explore the transport of fluid parcels during vortex merger, to provide a detailed view of the flow evolution, and to determine the value of the critical merging distance for baroclinic vortices.
Heat stress effects on morpho-physiological characters of Indian mustard ( Brassica juncea L . )

Effects of heat (high temperature) stress during terminal stage were investigated on plant height, primary branches/plant, siliquae on main shoot, seeds/siliqua, 1000-seed weight, seed yield, oil and protein content, leaf area index (60 DAS), specific leaf weight (80 DAS), crop growth rate (40-60 DAS), chlorophyll stability index (60 DAS) and harvest index of 22 advanced breeding lines/varieties of Indian mustard (Brassica juncea L.) during 2008-09. The genotypes were grown in randomized complete block design with three replications in two environments, viz., E1 (9 th November sowing) and E2 (25 th November sowing). Of the 45 days prior to physiological maturity, crop under E2 was exposed to higher mean daily temperature differential of 0.9-5.6C for 28 days. Genotypic differences were significant for all the characters except protein content and chlorophyll stability index. Environment effects were highly significant for all the moropho-physiological characters investigated. Genotypes x environment interactions were significant only for 1000-seed weight, leaf area index and crop growth rate. Leaf area index, specific leaf weight, crop growth rate, chlorophyll stability index and harvest index were drastically reduced under E2 by up to 49.4%, 52.1%, 76.2%, 54.2% and 28.9% respectively. The highest reduction in seed yield and its components ranged from 22.2% for seeds/siliqua to 69.2% for seed yield/plant. Four terminal high temperature tolerant genotypes as indicated by their low HIS for seed yield were BPR 538-10 (0.33), NRCDR 2 (0.44), RH 0216 (0.57) and NPJ 112 (0.58). Genotypes BPR 2, BPR 141-B-205-43 and BPR 540-6 having tolerance to high temperature for multiple characters were identified for utilization in the breeding programme.
Combining soft lithography and functional monolayers with electrodeposition to form nickel and zinc oxide nanostructures

Fabrication techniques for the production of nanostructures were investigated, specifically a combination of microcontact printing, chemical etching, and the electrodeposition of nickel and zinc oxide. Research on electrodeposition at (in some cases exclusively) the sides of structures was performed. Chemically etching a surface while using a monolayer to protect certain regions of the gold substrate from the etchant is a sensitive process. The quality of gold is of significant influence, and the nature of the etchant is very important. Conducting line patterns have been realized using chemical etching with octadecanethiol as an etch resist, although the monolayer is not intact after the etching step. The electrodeposition of nickel combines well with microcontact printing based patterning, resulting in a smooth nickel layer in the unpatterned regions and cleared area in the patterned regions. The deposition of zinc oxide is less regioselective; most of the deposit is found in the unpatterned regions while some deposit is found in the patterned regions. The conditions used in this research resulted in a rough deposit. Deposition on the sides of structures was partially successful. Nickel was deposited in a continuous line along the side of a structure, while zinc oxide deposit could be found on top of the structure as well. In one test, lines of silver were realized along nickel/gold lines which were produced by microcontact printing, etching and electrodeposition. Further research could include functionalizing surfaces with different monolayers, using etched functionalized structures to deposit other metals, or using a template to deposit zinc features in.
Magnetic properties induced by Mn atom in ZnO from theoretical study

Ab initio calculations using full-potential linearized augmented plane wave (FP-LAPW) method within density functional theory were performed in order study the effects of the incorporation of one Mn-atom in the structural, electronic and magnetic properties on ZnO compound. The calculation was carry out in the structure wurtzite employing the computational Wien2k code. Specifically, we investigate the Zn0.75Mn0. 25O concentration. We found that due to the one Mn incorporation the ZnO losses the semiconductor behavior, the new Zn0.75Mn0. 25O acquire a half-metallic ferromagnetic character with a magnetic spin polarization of 100% of the conduction carriers and a magnetic moment of 5.0 μβ/cell. This electronic and ferromagnetic behavior come from the strong hybridization of the Mn-3d and O-2p orbitals. The new Zn0.75Mn0. 25O is a good candidate for applications in the spintronic field.
VARIATION OF PROXIMATE COMPOSITION AND MINERALS WITHIN DIFFERENT PARTS OF CAPPARIS DECIDUA ( FORSSK . ) EDGEW . AS A FUNCTION OF HARVESTING SEASONS

Capparis decidua (C. decidua) is an important medicinal plant from the family Capparaceae. The present study explores the proximate (moisture, protein, crude fiber, dry matter) composition and minerals profile of various parts including stem bark, fruit shoot, root and flower of C. decidua harvested from Cholistan desert, Punjab, Pakistan in two seasons i.e., April and September. C. decidua fruits contained relatively higher amounts of proximate constituents followed by the flowers especially in case of protein while stem bark and roots mainly contained fiber. In comparison with other parts, the content of minerals was higher while traces of heavy metals i.e. Ni, Co and Cd were recorded in C. decidua fruits and flowers. Overall, harvesting seasons exhibited a significant (p<0.05) effect on the distribution of most of the constituents within different parts of Capparis decidua. The samples collected in September were found to be richer in protein and minerals and vice versa. The results of this study support that C. decidua fruits and flowers can be explored as a viable source of minerals and vegetable protein both for human beings and livestock to supplement nutrition.

The Role of Attachment Styles, Peer Relations, and Affections in Predicting Internet Addiction

The role of attachment styles, peer relations and affections in predicting Internet addiction is scrutinized in this study. It has been conducted with a total of 2,440 volunteer adolescents, out of which 1,588 are females and 852 are males, all between 14 and 19 years old and attending various high schools in Elazığ’s city center. In this study, the short form of the young Internet addiction test, the Relationship Scale Questionnaire, the Friendship Qualities Scale, and the Positive and Negative Affect Scale were used as data collection tools. Collected data were analyzed through correlational, multiple, and stepwise regression analyses. Study findings demonstrate that the independent variables of attachment styles, peer relations, and affections explain approximately 19% of Internet addiction. Furthermore, Internet addiction among adolescents was observed to be predominantly predicted by the variables of negative affection, conflict, and secure attachment. Attachment styles, peer relations, and affections were determined to predict Internet addiction, and the contribution of affections in this prediction is striking. The results are discussed within the framework of the literature, and recommendations have been given for future studies and applications.
Bs – B̄s mixing in Z ′ models with flavor-changing neutral curren

In models with an extraU(1)′ gauge boson family non-universal couplings to the weak eigenstates of the standard fermions generally induce flavor-changing neutral currents. This phenomenon leads to interesting results in various B meson decays, for which recent data indicate hints of new physics involving significant contributions from b → s transitions. We analyze theBs system, emphasizing the effects of a Z′ on the mass difference and CP asymmetries.  2004 Elsevier B.V.
SOLAR POWERED WIRELESS MONITORING SYSTEM OF ENVIRONMENTAL CONDITIONS FOR EARLY FLOOD PREDICTION OR OPTIMIZED IRRIGATION IN AGRICULTURE

This paper describes the design and realization of a smart electronic system, based on a Wireless Sensor Network, for wide-area monitoring of availability level and rapid changes of the water presence in the monitored soil, in order to guarantee, depending on application, early flood prediction, water savings in the optimized farmland irrigation as well as waste reduction and optimal use of water resources where its availability is low. The designed sensor node, equipped with a small PV panel to recharge the Li-Ion battery for feeding the entire system, by means of the different embedded sensors, is capable of detecting environmental parameters, the solar radiation level and soil temperature and moisture (i.e. water volume content) values. The sensors communicate with a central processing unit located on board, the ESP8266 SoC module, used both as data processing unit and as Wi-Fi transceiver to receive/transmit sensors data; the user near a sensor node, by a tablet or smartphone with an appropriate app, can collect information provided from sensors and share them with all users who use the same app, through peer to peer Wi-Fi or other internet connection.
Chapter 5 Watershed Modeling : National Institute of Food and Agriculture – Conservation Effects Assessment Project

S imulation modeling is arguably one of the most powerful scientific tools available to address questions, assess alternatives, and support decision making for environmental management. Watershed models are used to describe and understand the behavior of land and water systems under prevailing and projected conditions. They are increasingly used to evaluate potential water quality impacts of pollution control strategies, including agricultural practices. Modeling efforts constituted a major component of watershed-scale National Institute of Food and Agriculture–Conservation Effects Assessment Project (NIFA–CEAP). Chapter 5 describes the usefulness and challenges of watershed modeling and then summarizes activities, overall findings, and lessons learned from the modeling components of these studies. It also presents a set of recommendations for further enhancement and proper application of watershed modeling technologies for future conservation effects assessment at the watershed scale. Appraisal of individual and cumulative effects of conservation practices on water quality using monitoring data is ideal but can be costly and, in some cases, impractical (especially for retrospective studies). Controlled watershed experiments, particularly paired-watershed analysis, have been used to characterize how long-term changes in land use or implementation of pollution control actions alter hydrologic and water quality fluxes (Bishop et al. 2005). The wider use of these approaches, however, faces challenging issues, including (1) identifying control landscapes; (2) characterizing the role of type, location, and timing of individual practices when multiple practices are implemented over time; (3) overcoming lag time or delay in water quality response to changes in management due to large pools of legacy sediments and nutrients in soils and streams; and (4) addressing the uncertainty of methods for extension of results to other spatial and temporal scales. Watershed modeling in combination with strategic monitoring can address these issues (Easton et al. 2008b; Tomer and Locke 2011). Process-based distributed models facilitate dynamic hydrologic and water quality assessments under scenarios that cannot be investigated practically using actual watershed experiments. They can simulate what-if scenarios at varying spatial scales from fields to watershed outlets and at varying temporal scales from daily to decadal time steps. Watershed models are embodiments of scientific hypotheses. As such, they can be used within formal statistical hypothesis testing frameworks to answer questions relevant to watershed assessment and planning. For example, modeling scenarios can provide necessary information to examine the hypothesis that a targeted approach to implementation of conservation practices is significantly more effective
ON AERIAL PARTS OF Raphanus raphanistrum subsp . landra ( Moretti ex DC . ) Bonnier &

Raphanus raphanistrum subsp. landra is a wild annual plant from Brassicaceae family. Aerial parts of the plant can be used as food: the leaves can be used raw or cooked, flowers and young seedpods can be used raw in various dishes. In our country, it is considered a weed and it is not paying attention to its edible and pharmaceutical uses. The aim of this study is to evaluate the antioxidant, total polyphenols and flavonoid content of the ethanol extract of aerial parts (flowers, silique, and leaves) from this species. The plants were collected from ruderal areas. Ethanolic extracts from the flowers, silique, and leaves were analysed spectrophotometric. These preliminary studies on the phytochemical characteristics of Raphanus raphanistrum subsp. landra bring new and important information about nutraceutical importance and the possibility to be used in pharmaceutical industry.
THE ROLE OF INTERNET SELF-EFFICACY IN THE ACCEPTANCE OF AN EDUCATIONAL PORTAL

The widely used of Internet and educational technologies have greatly changed junior high teachers’ teaching methods and behaviors. Due to rapid changes in information and knowledge, many educational authorities have set up educational portals to support and improve junior high teachers’ teaching efficiency and effectiveness. An educational portal can provide large numbers of teaching materials and online discussion services to facilitate teachers’ teaching in class. However, many junior high teachers are still resistant to using the educational portals. Therefore, understanding which factors affect their acceptance of an educational portal are of primary concern. The current study builds a theo2018-0892 IJOI http://www.ijoi-online.org/ The International Journal of Organizational Innovation Volume 11 Number 2, October 2018 351 retical model affecting junior high teachers’ adoption of Easy Teaching Web of Taipei by combining self-efficacy theory and the technology acceptance model. Data were collected from 303 teachers at 16 junior high schools in Taipei, Taiwan. The partial least squares approach was used to test the measurement and structural model. The results support the proposed model, highlighting the important roles of Internet self-efficacy and perceived usefulness in predicting junior high teachers’ adoption of an educational portal. The practical implications are discussed, and further studies are suggested.
Brainscape ’ s “ Confidence-Based Repetition ” Methodology

Brainscape is a synchronous web and mobile flashcard program designed to improve the retention of declarative knowledge. It is different from other spaced-repetition flashcard programs in that its pattern for re-assessment is based not on a random algorithm nor on the user’s past history of correctness, but rather on the user’s own judgment of confidence in each piece of information – a process that Brainscape calls ConfidenceBased Repetition (CBR). In this paper, the designers of Brainscape evaluate the claim that CBR can optimize a learner’s use of study time, and we highlight the large body of research that supports this claim. Our analysis concludes that Brainscape is most useful when learners have a strong intrinsic motivation to learn the topic at hand. Brainscape is particularly useful for time-starved individuals preparing for a high-stakes exam or studying a foreign language that they are very interested in learning (rather than being forced to learn).
An Improved Gene Expression System to Generate Transgenic Arabidopsis Thaliana Plants Harboring a Bacillus Ginsengihumi Phytase Gene

We constructed a new vector system for heterologous gene expression in Arabidopsis thaliana. The construct contains a codon-optimized sequence encoding Bacillus ginsengihumi phytase behind an inducible plant-specific promoter for expression in root epithelial cells. The new vector introduced into the plant A. thaliana by Agrobacterium mediated transformation. We obtained several generations of transgenic A. thaliana plants with integrated Bacillus ginsengihumi phytase gene, as well as with an empty vector as a negative control. We tested several transgenic plants harboring the phyCg construct under the control of phosphate-starvation inducible Pht1;2 promoter and show that the phyCg gene is expressed at the mRNA level. Further characterization of these lines of plants will help us to design an improved transgenic strategy for the development of a root-specific heterologous system for the expression of bacterial phytases in plants.
Use of molecular markers to di ¡ erentiate between commercial strains of the button mushroom Agaricus bisporus

Agaricus bisporus is an edible basidiomycete cultivated industrially for food production. Different spawn and mushroom producers use genetically related A. bisporus strains frequently marketed as different products. In this paper we show that the use of suitable molecular markers reveals the high level of genetic homology of commercial strains of A. bisporus, and allows, at the same time, to distinguish between them. In the course of this work, a molecular marker potentially linked to the agronomic character `mushroom weight' has been identified by bulked segregant analysis. ß 2001 Federation of European Microbiological Societies.
