Abstract:

To meet the demands of the rotating structure for self-power, a novel gyromagnetic piezo-cantilever generator (GPCG) excited by the coupling between rotating magnets and those fixed on piezo-cantilever was presented. The influence of magnetic force (number and configuration of the magnets) and rotating speed on energy generation of the GPCG was investigated experimentally. The research results show that there are 9 optimal rotating speeds for the GPCG to achieve peak voltage at speed range of 0-1390r/min. With 1 magnet (ø12x2mm3) fixed on piezo-cantilever, the increasing number of rotating mag

Abstract:

Dense SiC-based composite ceramics were fabricated by means of the ex situ addition of TaC using solid-state spark plasma sintering (SPS). Commercially available β-SiC and TaC powders were chosen as raw materials. Electron backscattered diffraction (EBSD) analysis was conducted to investigate the grain boundary mapping of SiC-TaC composite ceramics. With the increase in TaC, the misorientation angles of the α-SiC phase shifted to a relatively small range. It was deduced that the ex situ pinning stress from TaC greatly suppressed the growth of α-SiC grains. The low β→α transformability of the s

Abstract:

Despite the consequences of night-shift work, the diet of night-shift workers has not been widely studied. To date, there are no studies related to food intake among emergency healthcare workers (HCWs). We performed a prospective observational study to assess the influence of night work on the diet of emergency HCWs. We monitored 24-h food intake during a day shift and the consecutive night, and during night work and the daytime beforehand. We analyzed 184 emergency HCWs’ food intakes. Emergency HCWs had 14.7% lower (−206 kcal) of their 24-h energy intake during night shifts compared to their

Abstract Abstract 3872 Background: Mesenchymal stromal cells are one of the components in the CLL microenvironment known to support leukemic cells survival and growth. Crosstalk between CLL B-cells and marrow-derived mesenchymal stromal cells (MSC) can modulate the activation of both cell types. Indeed we have shown that soluble factors secreted from CLL B cells can activate MSC with increased production of angiogenic cytokines (Blood. 2010. 116:2984). We hypothesize that MSC derived from CLL patients are modified by their interaction with leukemic cells in their gene expression profiles (GEP)

Oat (Avena sativa L.) is a vital cereal crop and serves as food, feed, and industrial material for many commercial growers. The presence of root-lesion nematodes (RLN; Pratylenchus spp.) in oat-cultivated areas of China is alarming because RLNs display an endo-migratory life cycle and rank third among the most damaging nematode pests (Jones et al. 2013). Their penetration and feeding cause necrotic lesions on the roots, which further dispose plants to other soilborne pathogens resulting in extensive root rots (LaMondia, 2003). In China, it has been reported that P. thornei harmed sugarcane and
