Theoretical Analysis of Cantilever Motion under Electrostatic Force

A motion of an electrostatic micromechanism with a cantilever movable electrode and a counter fixed electrode was studied theoretically by using the Rayleigh-Ritz method. As trial functions which express deformation states of the movable electrode approximately, deflection lines under applications of various uniform loads to the movable electrode were selected. In non-contact states of the movable electrode with the counter electrode, a hysteresis was confirmed in displacement (of the movable electrode)-applied voltage (between the both electrodes) curves of a voltage increasing and a voltage decreasing process. In contact states of the both electrodes, a hysteresis didn't appear in contact area-voltage curves and a threshold voltage above which a contact area increases rapidly with an increase of the applied voltage was derived. The threshold voltage, which determines an operation voltage of the mechanism, was almost proportional to L-2, T3t2 and do (L, T: the length and the thickness of the movable electrode, respectedly, do: the gap width between the movable and the counter electrode).
Vascular plants and plant habitats of Brush Creek Island, Lewis County, Kentucky, U.S.A.

A descriptive survey of the vascular flora and plant habitats of Brush Creek Island, a 6.7-ha Ohio River island in Lewis County, Kentucky, was conducted during 1995–1996 and 2012. Brush Creek Island (BC), one of three Ohio River islands politically a part of Kentucky, is currently under private ownership and projected as a future part of the Ohio River Islands National Wildlife Refuge. Two major habitats in 2012 were Vegetated Unconsolidated Shoreline and Bottomland Hardwood Forest, a final sere of Late Old Field and Immature Bottomland Hardwood Forest. Two additional 1996 habitats, a seasonal Riverine Emergent Wetland and Late Old Field, were altered through fluvial action and secondary succession processes by 2012. An annotated list consists of 330 species in 220 genera from 82 families. Taxa are composed of one Monilophyte, four Magnoliids, 76 Monocots, and 249 Eudicots. Ninety-three taxa (28.2%) are non-native adventive or naturalized spe-cies. Forty-eight taxa (54%) are classified as Kentucky invasive plants. A total of 189 species (57.3%) are hydrophytes. Ninety-five native or non-native taxa (28.8%) are Lewis County distribution records.
Causal Analysis of Hydrogen Acceptance

This paper presents and discusses a structural equation model on hydrogen acceptance. This model unravels the direct and indirect effects among personal characteristics, knowledge about hydrogen, perceptions, attitudes, and willingness to use hydrogen applications. In addition, indicators of differently colored information that can be provided by mass media have been included as explanatory variables. The estimated model indicates that colored information directly influences perceptions of hydrogen and indirectly influences attitudes about hydrogen and willingness to use it. In particular, negatively colored information decreases hydrogen acceptance, which cannot be counterbalanced by providing positively colored information. Furthermore, the model suggests that more factual knowledge about hydrogen increases its acceptance. The paper further discusses the likely development of hydrogen acceptance in the future and how practitioners can influence this.
Effect of different sowing dates on yield contributing traits of Mash bean (Vigna mungo L.)

Optimum sowing time and a promising variety are of prime importance to catch potential yield of any crop. Sowing time affects plant physiological and morphological specifications like effect on vegetative and reproductive periods, harvest time, yield and its quality. To achieve good yield, crop must be sown at appropriate time. In this regard, yield response of two mash bean genotypes namely mash-97 and ES-1 sown at different sowing dates was studied under field conditions during Kharif 2009 and 2010. Results of study showed that number of fruit bearing branches, 1000-grain weight, pods per plant, seeds per plant and grain yield were significantly affected by sowing dates and higher seed yield was recorded when crop was sown at June 28. The genotype ES-1 gave significantly the highest seed yield compared to mash-97.
Orai3 Calcium Channel Regulates Breast Cancer Cell Migration through Calcium-Dependent and -Independent Mechanisms

Orai3 calcium (Ca2+) channels are implicated in multiple breast cancer processes, such as proliferation and survival as well as resistance to chemotherapy. However, their involvement in the breast cancer cell migration processes remains vague. In the present study, we exploited MDA-MB-231 and MDA-MB-231 BrM2 basal-like estrogen receptor-negative (ER−) cell lines to assess the direct role of Orai3 in cell migration. We showed that Orai3 regulates MDA-MB-231 and MDA-MB-231 BrM2 cell migration in two distinct ways. First, we showed that Orai3 remodels cell adhesive capacities by modulating the intracellular Ca2+ concentration. Orai3 silencing (siOrai3) decreased calpain activity, cell adhesion and migration in a Ca2+-dependent manner. In addition, Orai3 interacts with focal adhesion kinase (FAK) and regulates the actin cytoskeleton, in a Ca2+-independent way. Thus, siOrai3 modulates cell morphology by altering F-actin polymerization via a loss of interaction between Orai3 and FAK. To summarize, we demonstrated that Orai3 regulates cell migration through a Ca2+-dependent modulation of calpain activity and, in a Ca2+-independent manner, the actin cytoskeleton architecture via FAK.
Packaging using microelectromechanical technologies and planar components

A novel millimeter-wave packaging structure was developed in which a micromachined low-loss planar component and flip-chip devices were integrated on a silicon substrate. A low-loss planar filter was achieved on a 7-mm-square silicon substrate employing an inverted microstrip line and a unique resonator. High attenuation in the stopband was also obtained by introducing a pole control technique. Fabrication of a compact K-band receiver front-end incorporating a built-in filter was realized using multilayered benzocyclobutene (BCB) and flip-chip bonding techniques. Furthermore, we propose an alternative BCB suspended structure and demonstrate a planar antenna for Ka-band applications. These technologies bring to reality high-performance compact packaged systems in millimeter-wave region applications.
Polystyrene Microparticles and the Functional Traits of Invertebrates: A Case Study on Freshwater Shrimp Neocardina Heteropoda

The excessive worldwide production of plastic materials results in omnipresent microplastic pollution. Scientific studies dealing with the impacts of microplastics on aquatic ecosystems focus mainly on the marine environment, documenting the effect on the functional traits of various organisms. Polystyrene, one of the most commonly used plastics, has become a widely used model in this respect. In our study, freshwater shrimps (Neocardina heteropoda) were exposed to virgin polystyrene particles (size 0.5 mm; nominal concentration 8 mgL−1), and their behavioral and physiological responses were compared to control shrimp. The exposed shrimps exhibited modified activity patterns (greater speeds, accelerations and distances moved), accompanied by a lowered standard metabolic rate (SMR). The observed effects differed in their progression from the 7th to 14th day of exposure, from undetectable changes (distance, SMR) to significant differences (speed, acceleration). Significant differences were also detected in the behavioral syndromes expressed by the exposed and controlled shrimps, indicating that the microplastics influence not only the particular traits, but also their functional relationships. As such, our study contributes to the integration of behavioral ecotoxicology in risk assessment, documenting the adverse performance of freshwater invertebrates exposed to microplastics with the potential to transpose the problem to higher levels of the food web.
Circular‐ring patch antenna with higher order mode for on‐body communications

A higher order mode (TM31) circular‐ring patch on‐body antenna with shorting pins for on‐body communications in wireless body area network is proposed. Using shorting pins, TM31 resonance mode was generated, while achieving compact low‐profile structure with monopole‐like radiation characteristics. To obtain wide bandwidth, an annular ring with shorting pins having TM31 mode is closely located around the circular patch. The antenna has the overall dimensions of 0.49 λ0 × 0.53 λ0 × 0.025 λ0 at 2.45 GHz in the industrial, scientific, and medical 2.45 GHz band (2.4–2.485 GHz) and the 10‐dB return loss bandwidth is 7.3% ranging from 2.35 to 2.53 GHz. © 2014 Wiley Periodicals, Inc.

Anxiolytic and Antidepressant Use and Burnout: Optimism as a Mediator in Spanish Nurses

The aim of this study was to analyze the relationship between burnout, the use of drugs (anxiolytics and antidepressants) and optimism in nurses. At the end of 2018, a cross-sectional descriptive study was carried out with a sample of actively employed nurses recruited by snowball sampling. The sample consisted of 1432 nurses in Andalusia (Spain), aged 22–58, who were working at the time of data collection, 83.2% of whom were women. Data were collected anonymously in an ad hoc questionnaire about sociodemographic information and use of anxiolytics and/or antidepressives: the Brief Burnout Questionnaire—Revised for Nurses (CBB-R) and the Life Orientation Test—Revised (LOT-R). Descriptive, mediation and moderation analyses were performed, with significant results having a p-value less than 0.05. The results on burnout showed significant relationships with use of the drugs. In particular, personal impact, job dissatisfaction and motivational abandonment were positively related to use of certain of the anxiolytics and antidepressants presented, while the correlation with the social climate was negative. Furthermore, optimism correlated negatively with drug use. Knowing that optimism can alleviate the repercussions of the use of drugs opens up new lines of research and the possibility of developing programs aimed at promoting a positive disposition in the face of complicated events.

Burden of cancer attributable to consumption of alcohol in Japan in 2015

Alcohol can cause or contribute to the development of many non-communicable diseases, including cancer. We calculated the proportion of cancer incidence and mortality in 2015 attributable to alcohol consumption in 2005. Data on alcohol consumption, provided in go, a traditional Japanese alcohol measurement unit, was derived from the 2005 Japanese National Health and Nutrition Survey for each sex and age group, then converted into grams of ethanol per day. The optimal consumption of alcohol for the purpose of this study was determined to be none, based on a global assessment derived from previous observational studies that have looked at the association between alcohol consumption and cancer. Using standard formulas, population attributable fractions (PAFs) for all cancers positively associated with alcohol drinking oral cavity, pharynx, esophagus, stomach, colorectum, liver, larynx, and female breast were calculated for each sex and age group and aggregated to obtain the PAF among total cancer incidence and mortality. For Japan in 2015, 59,838 cases of cancer incidence and 23,929 cancer deaths were attributable to alcohol consumption. The estimated PAF for cancer incidence and mortality attributable to alcohol consumption was 6.2% and 6.5%, respectively. For both cancer incidence and mortality, the highest percentage of alcohol-attributable cancer sites was esophageal (54.0% for incidence, 52.3% for mortality). Avoidance of alcohol consumption would reduce the burden of alcohol on cancer in Japan.
First-Principles Calculations of Thermal and Electrical Transport Properties of bcc and fcc Dilute Fe–X (X = Al, Co, Cr, Mn, Mo, Nb, Ni, Ti, V, and W) Binary Alloys

The adiabatic shear sensitivity of ultra-high-strength steels is closely related to their thermal conductivity. Therefore, it is essential to investigate the effects of alloying elements on the thermal conductivity of ultra-high-strength steel. In this study, the variation in the scattering behavior of electrons with respect to temperature and the mechanism of three-phonon scattering were considered for obtaining the contributions of electrons and phonons, respectively, to the thermal conductivity of alloys while solving the Boltzmann transport equation. By predicting the effect of ten alloying elements on the electronic thermal conductivity (κe), it was found that, at 1200 K, the doping of iron with Ni and Cr endowed iron with κe values of 24.9 and 25.7 W/m K, respectively. In addition, the prediction for the lattice thermal conductivity (κL), which was performed without considering point defect scattering, indicated that elements such as Al, Co, Mn, Mo, V, and Cr demonstrate a positive effect on the lattice thermal conductivity, with values of 3.6, 3.7, 3.0, 3.1, 3.9, and 3.8 W/m K, respectively. The contribution of κL is only 5–15% of the total thermal conductivity (κtotal). The alloying elements exhibited a similar effect on κtotal and κe. Δκi; the change in thermal conductivity with respect to κ0 owing to the alloying element i was evaluated according to the total thermal conductivity. These values were used to understand the effect of the concentration of alloying elements on the thermal conductivity of iron. The Δκi values of Ni, Co, and W were 6.44, 6.80, and 6.06, respectively, indicating a reduction in the thermal conductivity of iron. This paper provides theoretical guidance for the design of ultra-high-strength steels with a high thermal conductivity.
Microstrip line-fed L-strip patch antenna

A wideband electromagnetic-coupled single-layer microstrip patch antenna is studied experimentally. With dielectric and foam substrates of total thickness /spl sim/0.13 /spl lambda//sub 0/, a rectangular patch antenna with impedance bandwidth (SWR /spl les/2) of 49% and 3 dB gain bandwidth of 54% are obtained. It has an average gain of 6.5 dBi and stable radiation patterns across the passband. Furthermore, with the employment of a stacked parasitic patch, a 58%, impedance and gain bandwidth is achieved with similar radiation patterns and a higher average gain. A notable structure in the feeding design is that an inverted L-shaped strip is connected to the end of the microstrip line and no matching network is required.
Transforming the online learning space through advanced development retreats

Learning technologies have the potential to transform Higher Education, although multifaceted demands on staff time, confidence and training in using new technologies, and a lack of support can make this transformation difficult. The University of Huddersfield recently transitioned to a new virtual learning environment (VLE), which provided the opportunity to change the way staff view and use the new VLE for teaching and learning. As part of this project, three off-site retreats were run to help staff to reflect on and develop their teaching practice to better support student learning in the digital space and develop advanced online resources that support the democratisation of learning, close differential attainment gaps and give every student the best chance of success. Although much is written about different models of practice, there is a lack of theory and conceptualisation around changing practice. Examining the motivations and experiences of staff who participated provides insight into the challenges of implementing change on an institutional level, whilst examining their setup and design highlights ways to support staff during this process. Using participant feedback and experiences to underpin this research, we explore the immediate and ongoing outcomes of these off-site retreats to help transform the University’s approach to technology-enhanced learning.
A NOVEL NODE FAILURE MANAGEMENT FOR MOBILE AD HOC NETWORK USING ANT AGENTS

The node failure management is a puzzling task in Mobile Ad hoc Networks because of its dynamic nature. Even a single node or link failure can collapse the entire network. The source nodes are taking all responsibilities to manage node failures in the existing systems, but a link failure could be dealt dynamically with the help of alternative paths to deliver payloads without disturbing the source node. The end to end delay and the population of routing packets could be reduced enormously with an effective node failure management at intermediate level. The payload buffering at intermediate nodes need a special attention to decide the optimal buffer size. Here we propose a novel idea to handle node failures at run time to improve the following factors - high packet delivery ratio, low jitter effect and optimized usage of buffer space in mobile devices.

Precise correlation between rectilinear displacement and angular rotation is given by the helical saliency of the rotating armature. Preliminary results from a proto type version of the device are described.
A Review on Chemical Vapour Deposition of Two-Dimensional MoS2 Flakes

Two-dimensional (2D) materials such as graphene, transition metal dichalcogenides, and boron nitride have recently emerged as promising candidates for novel applications in sensing and for new electronic and photonic devices. Their exceptional mechanical, electronic, optical, and transport properties show peculiar differences from those of their bulk counterparts and may allow for future radical innovation breakthroughs in different applications. Control and reproducibility of synthesis are two essential, key factors required to drive the development of 2D materials, because their industrial application is directly linked to the development of a high-throughput and reliable technique to obtain 2D layers of different materials on large area substrates. Among various methods, chemical vapour deposition is considered an excellent candidate for this goal thanks to its simplicity, widespread use, and compatibility with other processes used to deposit other semiconductors. In this review, we explore the chemical vapour deposition of MoS2, considered one of the most promising and successful transition metal dichalcogenides. We summarize the basics of the synthesis procedure, discussing in depth: (i) the different substrates used for its deposition, (ii) precursors (solid, liquid, gaseous) available, and (iii) different types of promoters that favour the growth of two-dimensional layers. We also present a comprehensive analysis of the status of the research on the growth mechanisms of the flakes.
Foliar anatomical studies of Andropogon gayanus - Andropogon tectorum complex in Southwestern Nigeria

Foliar epidermal studies were carried out on accessions of Andropogon gayanus-Andropogon tectorum complex collected in Southwestern Nigeria with a view to providing additional characters of the two species of Andropogon to enhance the understanding of the taxonomic relationship between the two species. The epidermal preparation of the adaxial and abaxial surfaces of the leaf blade was made from the median part of well-matured leaf samples by the scrapping method. The analysis of both qualitative and quantitative characters revealed that study revealed that the costal zones of both adaxial and abaxial surfaces of all accessions studied showed similar features with little or no variation in their expression; epidermal cells are mostly rectangular with wavy walls, and the stomata encountered are paracytic. There was a unique occurrence of cluster of cells at the base of the macro hairs present in A. gayanus which is a diagnostic feature for its accessions collected. Kiwani, an unidentified polyploid accession, has the highest number of bands, the stomata are bigger, which is consistent with gigas effect occasioned by its polyploidy status. Glandular trichomes were present in both diploid and tetraploid of A. tectorum, a diagnostic feature for the species.
Diffusion of selected green supply chain management practices: an assessment of Chinese enterprises

Environmental pollution and resource depletion pressures have caused manufacturers in developing countries such as China to improve environmental performance. In response, thoughtful and innovative enterprises have implemented emergent environmental management practices including elements of green supply chain management (GSCM). Diffusion of these practices to enterprises occurs from internal and external influences. Given that GSCM practices can be viewed as management innovations, this article applies the seminal Bass model to analyse GSCM practices diffusion. Specifically, the Bass model for diffusion is used to evaluate data for ISO 14001 certification and eco-labelling practices in China. In this investigation, we evaluate the relative roles of innovation and imitation drivers for diffusion of these GSCM practices. We find that even though innovation is not insignificant, imitation plays a much larger role for these specific GSCM practices diffusions amongst Chinese enterprises. Managerial and policy implications of these and other findings are also discussed.
Grid Header Election by Predetermining in Mobile Ad-Hoc Networks

ABSTRACT Mobile ad hoc networks (MANETs) consist of a set of mobile nodes without deploying base stations. Since mobile nodes are energy limited, designing an energy-efficient routing protocol is an important issue in MANETs. Among existing routing protocols, grid routing protocols are usually used for saving energy. In grid routing protocols, only few nodes act as grid headers to maintain connectivity of network and other nodes can be tuned into idle mode to save energy. In traditional grid header election, such as GRID and LB2R, a robust grid header is selected without considering energy consumption. All nodes need to broadcast elected packets to compete as a grid header once the residual energy of current grid header is insufficient. Hence, nodes consume the redundant energy without transmitting data. To solve this problem, we propose a grid header election by predetermining (GHEP) in MANETs. In GHEP, a node will be selected as a candidate node in advance. Whenever the residual energy of grid header is insufficient, the candidate node becomes as the new grid header immediately without sending extra controlled packets for election. Simulation results showed that our proposed GHEP outperformed GRID and LB2R in different number and moving speed of nodes. Moreover, GHEP could also save more energy than GRID and LB2R.
