A variety of deposition methods for two-dimensional crystals have been demonstrated; however, their wafer-scale deposition remains a challenge. Here we introduce a technique for depositing and patterning of wafer-scale two-dimensional metal chalcogenide compounds by transforming the native interfacial metal oxide layer of low melting point metal precursors (group III and IV) in liquid form. In ...

this study aimed to develop techniques for purification of cyanotoxins dissolved in water -particularly those produced by microcystis aeruginosa species - using natural clay, chemically modifiednatural clay, commercial clay and ion exchange and adsorbent resins. except for natural clay, chemical pretreatment was required to increase the adsorption capacity of the treatment materials. all the cl...

We present the design and evaluation of a flexible UHF RFID reader suited for experimentation. Our reader is built using the USRP software radio platform in conjunction with software we developed in the GNU Radio framework. We believe this is the first inexpensive tool that readily enables changes to the physical and MAC layer of RFID systems. Our reader further has sufficient performance to in...

Unlike traditional virus isolation and sequencing approaches, sequence-independent amplification based viral metagenomics technique allows one to discover unexpected or novel viruses efficiently while bypassing culturing step. Here we report the discovery of the first Sicinivirus isolate (designated as strain JSY) of picornaviruses from commercial layer chickens in mainland China by using a vir...

The use of wireless mobile ad-hoc networks (MANETs) has gained rapid momentum, both in the commercial and non-commercial sectors. In the commercial sector, sensor networks are being considered for deployment for a wide variety of purposes including to sense robustness of elevators, bridges, and other structures and to explore the earth (e.g., oil, soil type, etc.). Examples in the noncommercial...

Artificial lighting is one of the most powerful management tools available to commercial layer producers. Artificial light allows anticipating or delaying the beginning of lay, improving egg production, and optimizing feed efficiency. This study aimed at comparing the performance of commercial layers submitted to lighting using different LED colors or conventional incandescent lamps. The study ...

Salmonella is a globally widespread food-borne pathogen having major impact on public health. All motile serovars of Salmonella enterica of poultry origin are zoonotic, and contaminated meat and raw eggs are an important source to human infections. Information on the prevalence of Salmonella at farm/holding level, and the zoonotic serovars circulating in layer poultry in the South and South-Eas...

Problem statement: Escherichia coli isolates are the most common bacterial agents of salpingitis in commercial layer hens. The objectives of this study were to determine the phylogenetic groups/subgroups and antibiotic resistance of E. coli isolates from salpingitis cases in commercial layer hens farms in southeast of Iran. Approach: One hundred twenty one E. coli isolates from oviducts of laye...

Commercial poultry farms (n° 523), located in all the six regions of Nigeria were sampled with a view to generate baseline information about the distribution of Salmonella serovars in this country. Five different matrices (litter, dust, faeces, feed and water) were collected from each visited farm. Salmonella was isolated from at least one of the five matrices in 228 farms, with a farm prevalen...

The objective of the current study was to identify QTL conferring resistance to Marek's disease (MD) in commercial layer chickens. To generate the resource population, 2 partially inbred lines that differed in MD-caused mortality were intermated to produce 5 backcross families. Vaccinated chicks were challenged with very virulent plus (vv+) MD virus strain 648A at 6 d and monitored for MD sympt...
