Performance Analysis of Wind-Induced Piezoelectric Vibration Bimorph Cantilever for Rotating Machinery

Harvesting the energy contained in the running environment of rotating machinery would be a good way to supplement energy to the wireless sensor. In this paper, we take piezoelectric bimorph cantilever beam with parallel connection mode as energy collector and analyze the factors which can influence the generation performance. First, a modal response theory model is built. Second, the static analysis, modal analysis, and piezoelectric harmonic response analysis of the wind-induced piezoelectric bimorph cantilever beam are given in detail. Finally, an experiment is also conducted. The results show that wind-induced piezoelectric bimorph cantilever beam has low resonant frequency and stable output under the first modal mode and can achieve the maximum output voltage under the resonant condition. The output voltage increases with the increase of the length and width of wind-induced piezoelectric bimorph cantilever beam, but the latter increasing amplitude is relatively smaller. In addition, the output voltage decreases with the increase of the thickness and the ratio of metal substrate to piezoelectric patches thickness. The experiment showed that the voltage amplitude generated by the piezoelectric bimorph cantilever beam can reach the value simulated in ANSYS, which is suitable for actual working conditions.
A Study on Excellent Talk Show Hosts’ Verbal Language for College English Teachers to Improve Class Atmosphere

Classroom atmosphere plays an important role in second language learning. Although there are many factors that can affect the classroom atmosphere, such as students’ learning motivation, and etc., college English teachers also play an important role, especially teachers’ verbal language (teacher talk) in class, which is still the main way for teachers and students to interact with each other in class. Based on the great success of excellent TV talk shows in the atmosphere and similarities between English class and TV talk shows, in this paper, it is explored by specifying on the good qualities of TV talk show hosts’ words which are worthwhile for college English teachers to learn from. On the basis of this, some suggestions as to refine college English teachers’ words to improve class atmosphere were put forward, thus improving classroom qualities and foreign language acquisition.

Milled legume grain as urease source for the ammonization of elephant grass hay

The objective of this work was to evaluate the use of soybean ( Glycine max ), pigeon pea ( Cajanus cajan ), and jack bean ( Canavalia ensiformis ) as urease sources for elephant grass ( Pennisetum purpureum ) hay ammoniated with urea. The experimental design was completely randomized in a double factorial arrangement with one additional treatment: 4 urease source levels x 3 urease sources + 1 control. Chemical-bromatological analyses and carbohydrate fractionation were performed in the hay, and cumulative gas production in vitro was determined. There were interactions between urease level and source for neutral detergent fiber and acid detergent fiber, in which 1 and 2% jack bean lowered acid detergent fiber values, and 2% jack bean and 3% soybean reduced lignin content. The addition of milled legume grains reduces fiber components and increases non protein nitrogen content in elephant grass hay ammoniated with urea. Adding 4% milled soybean increases gas production in the soluble fraction.
The Effect of Some Antioxidants on Protein Banding Patterns and Nucleic Acids Content of Three Genera from Dematiaceous Fungi

SDS-PAGE electrophoresis was used to investigate the effect of four antioxidants on protein banding patterns of mats and metabolic solutions of three genera of Dematiaceous fungi viz. Alternaria tenuissima; Curvularia inaequalis and Trichoderma aureaviride. The antioxidants were vitamin E; ß-carotene (fat soluble vitamins); vitamin C and folic acid (water soluble vitamins). Quantitative estimation of RNA and DNA was also recorded for the studied fungi under the effect of these antioxidants. The highest molecular weight bands was recorded in Alternaria tenuissima and Curvularia inaequalis (mats & metabolic solution) treated with vitamin C, while the lowest molecular weight bands was recorded when treated with vitamin E. The water soluble antioxidants induced the accumulation of proteins but the oil soluble antioxidants suppressed this parameter. Alternaria tenuissima (mats & metabolic solution) produced lower number of bands than the control sample when grown under the effect of each antioxidant, while Curvularia inaequalis mats produced higher number of bands than the control sample. Trichoderma aureoviride produced higher number of bands than the control sample under the effect of vitamin C in mats and under the effect of â-carotene, vitamins C and E in metabolic solution. Folic acid had the ability to increase the concentration of nucleic acids "RNA and DNA". On the other hand, â-carotein had the ability to decrease the concentration of nucleic acids of the studied fungi.
Attenuating multiple-related imaging artifacts using combined imaging conditions

ABSTRACTThe objective of prestack depth migration is to position reflectors at their correct subsurface locations. However, migration methods often also generate artifacts along with physical reflectors, which hamper interpretation. These spurious reflectors often appear at different spatial locations in the image depending on which migration method is used. Therefore, we have devised a postimaging filter that combines two imaging conditions to preserve their similarities and to attenuate their differences. The imaging filter is based on combining the two constituent images and their envelopes that were obtained from the complex vertical traces of the images. We have used the method to combine two images resulting from different migration schemes, which produce dissimilar artifacts: a conventional migration method (equivalent to reverse time migration) and a deconvolution-based imaging method. We show how this combination may be exploited to attenuate migration artifacts in a final image. A synthetic mode.
INTRA-REPETITION VARIABLE RESISTANCE TRAINING: PART 1-AN OVERVIEW

This series of reviews focuses on changes in external resistance during a repetition, and the ability to generate maximal muscular strength and power in a repetition. Part 1 focuses on the types and effects of Variable Resistance on neuromuscular adaptations. Part 2, which will follow in an upcoming edition of EJHM, explores the practical applications and methodological findings to the design of training programs that most effectively enhance maximal force production. The use of new strategies will help athletes and specialists improve performance, and will increase effectiveness of strength-training programs. The ability to generate maximal force is influenced by the time available to develop force, the magnitude of the external resistance, and the amount of resistance progressively added or reduced. This Part analyzes the most common ways of modifying external resistance using chains and elastic bands. These reviews discuss acute changes in the muscle environment and the impact that this has in maximal force production over different expressions of strength. Intra-Repetition Variable Resistance (irVR) training has been shown to impact different neuromuscular factors in many specific ways. Therefore, an understanding of the biological basis of maximal force production is essential for developing training programs that effectively enhance human strength capacity.
Characterization of EST-derived microsatellites in cassava (Manihot esculenta Crantz.)

Cassava (Manihot esculenta Crantz) is a staple food for millions of people both in the tropics and subtropics and is increasingly being used as an industrial crop for the production of starch and other products. Currently, the number of molecular markers available for cassava genetic studies is limited. This study was conducted for the characterization of Expressed Sequence Tags (EST)-derived microsatellites or Simple Sequence Repeats (SSRs) in cassava (Manihot esculenta Crantz). Ninety six EST- SSRs previously identified insilico, were validated and screened for polymorphism using a diverse set of cassava genotypes. Using the optimized PCR conditions, these SSRs were screened for polymorphism using two diversity panels: panel 1 which comprises of cassava landraces and elite clones cultivated in Africa while panel 2 which comprises of cultivated cassava from Africa, Asia and Latin America, as well as wild Manihot species and castor bean (Ricinus communis) belonging to the family Euphorbiaceae. About thirty one SSRs were polymorphic in panel 1 while forty two were polymorphic in panel 2. A greater number of polymporhism was observed for panel 2 compared to panel 1, as expected since panel 2 comprises a greater genetic diversity. A total of seventy alleles were detected in panel 1 and ninety six for panel 2. The number of alleles per locus ranged from one to four by using these new polymorphic SSRs, with distinct genetic relationships between different genotypes. The cluster analysis showed consistency on the available information of the accessions under study, thus showing that the markers can be used for cassava genotyping
Efficacy of natural zeolite and pigments on yolk color and performance of laying hens

An in vivo study was conducted to evaluate pigment adsorptive ability of a natural zeolite in laying hens. This experiment was performed with three hundred sixty Hy-line W-36 strain of laying hens at 43 weeks of age. After a two weeks adaptation period, they received six experimental diets with a 3 × 2 factorial arrangement in a completely randomized design. The experimental groups were fed with cornsoy-wheat based diets containing three levels of natural zeolite (0.0, 1.5 and 3.0%) and 2 levels of synthetic pigment (0.0 and 0.04%) for a 6-week period. Each treatment contained 60 birds, which were randomly divided into 4 replicates of 15 birds each. The results showed that egg production, egg weight, shell thickness and the shell percent values did not significantly differ between treatments, but that the yolk color index was significantly reduced and increased by the addition of zeolite and pigment levels to the diet, respectively.
Maximizing the Potential of Mentoring: A Framework for Pre-service Teacher Education

Within the professional placement component of pre-service teacher education, mentoring has become a strategy that is used during the practical application of learning to teach. In this paper, we examine mentoring in the pre-service teacher education context by proposing a theoretically based framework for mentoring in this context. Firstly, the nature of mentoring along with mentoring in the context of pre-service teacher education is explored. A mentoring framework that has been developed to enable pre-service teacher educators to maximize the potential use of mentoring during the professional placement component of a pre-service teacher education degree is then proposed.
Identification and Classification of Sand Flies Species and It’s Habitats in El-Kadaba Village, White Nile State, Sudan

Sand flies are a group of dipterans insects belonging to the subfamily Phlebotomine, family Psychodidae. Members of sand flies are delicate and can be easily recognized by their brownish colour, small size (1.5-2.5 mm), hairy appearance, long slender legs, jerky flight pattern and the characteristic manner in which they hold their pointed wings at an angle of 45° above their body. In this study, an entomological survey was carried out during June 2008 in El-Kadaba village (White Nile State, Sudan) to determine sandfly fauna and to identify sand flies vector(s). Sandflies were collected using sticky paper and light traps. Ten species of sandflies were recorded, three Phlebotomus species and seven Sergentomyia species of these sandflies, P. rodhaini was collected only from Acacia seyal/Balanitiesaegyptiaca at the Island whereas S. hunti was collected from the Acacia nilotica forest only of the total collections, P. orientalis representing 3.80% (248 specimens) of the total collection and P. papatasiwere 3.11% of the collection. The abundant species recorded in the area were S. sqaumipluer is (39.76%), S. clydei (25.89%) and S. antennatus (12.39%). Phlebotomusorientalis were collected significantly in higher numbers from the Island (Acacia/Balanities thicket) (5.50±0.98), than the village (3.25±0.72). According to results of this study we recommended the following: more studies must be done in future to cover all the belt of sand flies to determine all species of sand flies in Sudan. Annually Entomological survies must be done to determine density of Sandfly Vectors and Encourage the use of personal protection tools (ITNs), repellents, and improving of houses to avoid bite of sand fly.
Micro Solid Oxide Fuel Cells on Glass Ceramic Substrates

Miniaturized solid oxide fuel cells are fabricated on a photostructurable glass ceramic substrate (Foturan) by thin film and micromachining techniques. The anode is a sputtered platinum film and the cathode is made of a spray pyrolysis (SP)‐deposited lanthanum strontium cobalt iron oxide (LSCF), a sputtered platinum film and platinum paste. A single‐layer of yttria‐stabilized zirconia (YSZ) made by pulsed laser deposition (PLD) and a bilayer of PLD–YSZ and SP–YSZ are used as electrolytes. The total thickness of all layers is less than 1 µm and the cell is a free‐standing membrane with a diameter up to 200 µm. The electrolyte resistance and the sum of polarization resistances of the anode and cathode are measured between 400 and 600 °C by impedance spectroscopy and direct current (DC) techniques. The contribution of the electrolyte resistance to the total cell resistance is negligible for all cells. The area‐specific polarization resistance of the electrodes decreases for different cathode materials in the order of Pt paste > sputtered Pt > LSCF. The open circuit voltages (OCVs) of the single‐layer electrolyte cells ranges from 0.91 to 0.56 V at 550 °C. No electronic leakage in the PLD–YSZ electrolyte is found by in‐plane and cross‐plane electrical conductivity measurements and the low OCV is attributed to gas leakage through pinholes in the columnar microstructure of the electrolyte. By using a bilayer electrolyte of PLD–YSZ and SP–YSZ, an OCV of 1.06 V is obtained and the maximum power density reaches 152 mW cm−2 at 550 °C.
Seasonal Variation of PAHs in Marshy Soils from Warri City, Nigeria

Seasonal variation has been used to analyse the levels of Polycyclic Aromatic Hydrocarbons PAHs in marshy soils in Warri city, Niger Delta region in Southern Nigeria. Soil samples were collected from four locations in Warri city- Ekpan, Ogunu, Ugboroke, and Okotie sawmill and labelled ST 1, ST 2, ST 3 and ST 4 respectively. Control samples were also collected at Agbarho, 20km away from Warri and labelled ST 5. The objective of this study is to compare marshy soil levels of PAHs in dry and rainy season and examine their variation base on the type of PAHs detected in relation to the characteristics of the different locations. The samples were collected from January to March for dry season and June to August for rainy/wet season. Levels of 16 USEPA priority PAHs were determined using GC-FID. Highest total concentration for individual PAHs in the soil samples was 1.069 mg/kg for benzo(a)pyrene in dry season ST4 (Okotie sawmill) sample. At the control station ST 5, sample with highest dry season concentration was 0.519 mg/kg of benzo(ghi)perylene. In the rainy season, PAHs were majorly below detection limit or found in minute quantity at the study location and control. ST4 had highest total PAHs concentration of 1.911 mg/kg in dry season. The station with the lowest concentration was ST1 with a value of 0.009 mg/kg in rainy season. The results of this analysis further revealed that total PAHs concentration in Warri city were higher than at the control station (Agbarho).
IAEA coordinated research project on nuclear data for charged-particle monitor reactions and medical isotope production

An IAEA coordinated research project was launched in December 2012 to establish and improve the nuclear data required to characterise charged-particle monitor reactions and extend data for medical radionuclide production. An international team was assembled to undertake work addressing the requirements for more accurate cross-section data over a wide range of targets and projectiles, undertaken in conjunction with a limited number of measurements and more extensive evaluations of the decay data of specific radionuclides. These studies are nearing completion, and are briefly described below.
A Hybrid Variational Formulation for Strain GradientElasticity Part I: Finite Element Implementation

The present paper starts with Mindlin’s theory of the strain gradient elasticity, based on three additional constants for homogeneous materials (besides the Lamé’s constants), to arrive at a proposition made by Aifantis with just one additional parameter. Aifantis’characteristic material length g2, as it multiplies the Laplacian of the Cauchy stresses, may be seen as a penalty parameter to enforce interelement displacement gradient compatibility also in the case of a material in which the microstructure peculiarities are in principle not too relevant, but where high stress gradients occur. It is shown that the hybrid finite element formulation – as proposed by Pian and generalized by Dumont for finite and boundary elements – provides a natural conceptual framework to properly deal with the interelement compatibility of the normal displacement gradients, in which “corner nodes” are not an issue. Nonsingular fundamental solutions – domain interpolation functions – are presented for two-dimensional (2D) and three-dimensional (3D) problems, with the generation of families of finite elements that may be implemented in a straightforward way. Since the experimental data available in the technical literature are still scarce and the numerical results are in part questionable, consistency is assessed by means of patch tests and by investigating the spectral properties of the matrices derived for some 2D plane strain elements. The present developments, although of academical relevance, involve too many degrees of freedom to be considered for practical applications and are actually intended as a step toward a boundary-only implementation in terms of singular fundamental solutions.
Testing weak form informational efficiency on the Romanian capital market

The informational efficiency of the Romanian capital market was previously studied, by different approaches. The first condition that needs verification is that of weak form informational efficiency. The present paper aims to make contributions in this direction, namely to test weak form efficiency, on a sample composed of recent data, collected from the most liquid companies listed on our country’s capital market. For this approach, we use the unit root tests. The results are useful to potential investors, interested to find out whether they can or cannot obtain excessive earnings, by studying stock prices history.
Photogrammetric Techniques for Promotion of Archaeological Heritage: the Archaeological Museum of Parma (italy)

In a context rich in history and cultural heritage, such as the Italian one, promotion and enhancement of historical evidences are crucial. The paper describes the case study of the Archaeological Museum of Parma, which, for the main part, conserves evidences found in the roman archaeological site of Veleia (Piacenza, Italy). To enhance the comprehension of the past, the project aims to promote the exhibits through new digital contents, in particular 3D models and AR applications, to improve their usability by the public. Projects like this pose some difficulties especially in data acquisition and restitution due to complexity of the objects and their dimension and position that are not always adequate for an easy survey. Furthermore, in this case, it was necessary to find a solution that takes into account, on one hand, the necessity of a high degree of detail to ensure high metric quality and, on the other hand, the need of producing small files, in order to easy load and consult them on the web or smartphone applications. For all these reasons, close-range photogrammetry was considered the most adequate technique to produce the major part of the models. In this paper, particular attention will be dedicated to the description of the survey campaign and data processing, underlining difficulties and adopted solutions, in order to provide a methodological summary of the actions performed.
Three dimensional lithospheric structure of the western continental margin of India constrained from gravity modelling: implication for tectonic evolution

This paper describes a 3-D lithospheric density model of the Western Continental Margin of India (WCMI) based on forward modelling of gravity data derived from satellite altimetry over the ocean and surface measurements on the Indian peninsula. The model covers the north-eastern Arabian Sea and the western part of the Indian Peninsula and incorporates constraints from a wide variety of geophysical and geological information. Salient features of the density model include: (1) the Moho depth varying from 13 km below the oceanic crust to 46 km below the continental interior; (2) the lithosphere–asthenosphere boundary (LAB) located at depths between 70 km in the southwestern corner (under oceanic crust) and about 165 km below the continental region; (3) thickening of the crust under the Chagos–Laccadive and Laxmi Ridges and (4) a revised definition of the continent–ocean boundary. The 3-D density structure of the region enables us to propose an evolutionary model of the WCMI that revisits earlier views of passive rifting. The first stage of continental-scale rifting of Madagascar from India at about 90 Ma is marked by relatively small amounts of magmatism. A second episode of rifting and large-scale magmatism was possibly initiated around 70 Ma with the opening of the Gop Rift. Subsequently at around 68 Ma, the drifting away of the Seychelles and formation of the Laxmi Ridge was a consequence of the down-faulting of the northern margin. During this second episode of rifting, the northern part of the WCMI witnessed massive volcanism attributed to interaction with the Reunion hotspot at around 65 Ma. Subsequent stretching of the transitional crust between about 65 and 62 Ma formed the Laxmi Basin, the southward extension of the failed Gop Rift. As the interaction between plume and lithosphere continued, the Chagos–Laccadive Ridge was emplaced on the edge of the nascent oceanic crust/rifted continental margin in the south as the Indian Plate was moving northwards.
