Tungsten oxide (WO 3 ) thin films for gas sensing have been successfully deposited using reactive direct current (DC) magnetron sputtering at different deposition temperatures (300 °C, 400 °C and 500 °C). The structural, morphological properties, thickness composition investigated X-ray diffraction (XRD), scanning electron microscopy (SEM) Rutherford backscattering spectrometry (RBS) techniques...

Erbium (Er)-doped Aluminum Nitride (AlN) thin films were deposited and fabricated on Si (100) (111) substrates in a Nitrogen atmosphere using the plasma magnetron sputtering technique. The thermally annealed at 900 °C Argon (Ar) atmosphere. samples irradiated with protons dose of 1 × 1014 ions/cm2 which carried an incident energy 335 keV, tandem pelletron accelerator. Rutherford backscattering ...

The Dead Sea is an excellent natural laboratory for the investigation of Reactive Bromine Species (RBS) chemistry, due to the high RBS levels observed in this area, combined with anthropogenic air pollutants up to several ppb. The present study investigated the basic chemical mechanism of RBS at the Dead Sea using a numerical one-dimensional chemical model. Simulations were based on data obtain...

Roberts Syndrome (RBS) and Cornelia de Lange Syndrome (CdLS) are severe developmental maladies that present with nearly an identical suite of multi-spectrum birth defects. Not surprisingly, RBS and CdLS arise from mutations within a single pathway--here involving cohesion. Sister chromatid tethering reactions that comprise cohesion are required for high fidelity chromosome segregation, but cohe...

A practical design of non-trivial rule-based systems requires a systematic, structured and consistent approach. The paper focuses on selected issues in RBS knowledge engineering. Some ideas on combining knowledge engineering with software engineering are discussed. Furthermore, results of RBS design tools survey are enclosed. In the paper an original design and implementation methodology for RB...

صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...

MOTIVATION To better analyze low-resolution cryo electron microscopy maps of macromolecular assemblies, component atomic structures frequently have to be flexibly fitted into them. Reaching an optimal fit and preventing the fitting process from getting trapped in local minima can be significantly improved by identifying appropriate rigid bodies (RBs) in the fitted component. RESULTS Here we p...

In autumn 2014, with great effort by the Ministry of Health, Labour and Welfare, the research group will obtain several vials of redback spider (RBS) antivenom for emergency use. However, these small amounts of antivenom are insufficient to cover the demands from majority of hospitals in Japan. The research group carefully discussed the domestic RBS antivenom production by themselves for this e...

BACKGROUND In recent years, several studies have correlated pitch count with an increased risk for injury among baseball pitchers. However, no studies have attempted to draw a similar conclusion based on number of carries by running backs (RBs) in football. PURPOSE To determine whether there is a correlation between number of carries by RBs in the National Football League (NFL) and risk of in...
