Conceptual design and kinematic analysis of a novel parallel robot for high-speed pick-and-place operations

This paper deals with the conceptual design, kinematic analysis and workspace identification of a novel four degrees-of-freedom (DOFs) high-speed spatial parallel robot for pick-and-place operations. The proposed spatial parallel robot consists of a base, four arms and a 1½ mobile platform. The mobile platform is a major innovation that avoids output singularity and offers the ...

Why employees stay: the roles of psychological ownership, territoriality and work relationship closeness in affecting employee turnover intention

Drawing on a tripartite perspective on attitudes, this study examines the influence of psychological ownership and territoriality on turnover intention, as well as the moderating role of work relationship closeness on the relationship between territoriality and turnover intention. Analyses of longitudinal data collected from 341 employees in three Chinese automobile manufacturing ...

Effect of porosities on tensile properties of laser-welded Al-Li alloy: an experimental and modelling study

Aluminium–lithium (Al-Li) alloys are very attractive for aerospace applications due to their outstanding properties, such as high specific strength, high rigidity and good resistance to corrosion and fatigue, compared to conventional aluminium alloys. The butt joints of Al-Li 2A97-T3 alloy sheet produced by fibre laser welding with ER2319 filler wire were investigated in this ...

Facile Synthesis of Silver Nanowires with Different Aspect Ratios and Used as High-Performance Flexible Transparent Electrodes

Silver nanowires (Ag NWs) are the promising materials to fabricate flexible transparent electrodes, aiming to replace indium tin oxide (ITO) in the next generation of flexible electronics. Herein, a feasible polyvinylpyrrolidone (PVP)-mediated polyol synthesis of Ag NWs with different aspect ratios is demonstrated and high-quality Ag NWs transparent electrodes (NTEs) are fabricated ...

GNS4, a novel allele of DWARF11, regulates grain number and grain size in a high-yield rice variety

Background Rice plays an extremely important role in food safety because it feeds more than half of the world’s population. Rice grain yield depends on biomass and the harvest index. An important strategy to break through the rice grain yield ceiling is to increase the biological yield. Therefore, genes associated with organ size are important targets for rice breeding. Results We ...

Design approach for optimization of a piston ring profile considering mixed lubrication

To reduce the friction of a piston ring while maintaining a large oil film load-carrying capacity, an approach comprising of the inverse method and the sequential quadratic programming algorithm was proposed. The approach considers the variation of mixed lubrication and variable lubricant viscosity with temperature along the engine stroke, is developed to optimize the profile of a ...

Waste Fiber Powder Functionalized with Silver Nanoprism for Enhanced Raman Scattering Analysis

Biomass disks based on fine powder produced from disposed wool fibers were prepared for surface-enhanced Raman scattering (SERS). The wool powders (WPs) were modified by silver nanoprisms via an assembly method and then pressed into disks using a hydraulic laboratory pellet press. Scanning electron microscopy (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy ...

MTB-specific lymphocyte responses are impaired in tuberculosis patients with pulmonary cavities

Objective Tuberculosis (TB), an infectious disease caused by the bacillus Mycobacterium tuberculosis (MTB), is a global health problem. Because the failing immune response in the lung can lead to formation of a pulmonary cavity, this study was designed to clarify MTB-specific lymphocyte responses in TB patients with pulmonary cavities. Methods We utilized culture filtrate protein ...

Investigation of methane adsorption on chlorite by grand canonical Monte Carlo simulations

In this paper, the methane adsorption behaviours in slit-like chlorite nanopores were investigated using the grand canonical Monte Carlo simulation method, and the influences of the pore sizes, temperatures, water, and compositions on methane adsorption on chlorite were discussed. Our investigation revealed that the isosteric heat of adsorption of methane in slit-like chlorite ...

Lower abdominal gossypiboma mimics ovarian teratoma: a case report and review of the literature

Background Gossypiboma is a serious and potentially dangerous medico-legal problem. Case presentation We present a case of lower abdominal gossypiboma that presented as an abdominal cystic mass mimicking ovarian teratoma. The mass and the adhesive intestine loop were en blocly resected. The cut section confirmed gossypiboma diagnosis. Conclusions The present experience and related ...

Zinc Oxide Coating Effect for the Dye Removal and Photocatalytic Mechanisms of Flower-Like MoS2 Nanoparticles

Flower-like MoS2 nanoparticles (NPs) consist of ultra-thin MoS2 nanosheets are synthesized via a facile one-pot hydrothermal method. The MoS2/ZnO p-n heterostructure is formed by coating n-type ZnO on the surface of flower-like MoS2 NPs through the seed-mediate route and post-annealing treatment. The effects for the dye removal and photocatalytic performances after ZnO coating are ...

Viral dynamics of an HIV model with latent infection incorporating antiretroviral therapy

In this paper, we construct an HIV infection model which includes latent infection, logistic growth for healthy CD4 + T-cells, and antiretroviral therapy. We obtain the global asymptotic stability of the uninfected equilibrium by constructing a Lyapunov function, and we give a sufficient condition for the local asymptotic stability of the infected equilibrium. We also use the latin ...

The histological characteristics, age-related thickness change of skin, and expression of the HSPs in the skin during hair cycle in yak (Bos grunniens)

Objective This experiment was conducted to study the histological characteristics, age-related thickness changes, and expression of HSPs in the skin of yak. Methods A total of 20 yaks (10 males and 10 females) were used. Different regions of the normal skin of three different ages (newborn, half-year-old and adult) of yaks were harvested for histological study and thickness ...
