methods for measuring toxicity or respiratory activity of microbial cultures can be used as tools for assessing the presence of chemicals and their impact on the streams. the proposed toxicity test is based on the respirometric characteristics of the bacteria according to the principals of biolog’s microplate system. as the microorganism are utilizing the carbon source (peptone), the reductio...

Signals mediated by fibroblast growth factor (FGF) family members are transduced into target cells by tyrosine kinase transmembrane receptors (FGFRs). The FGFR family includes four distinct receptors, FGFR-1, −2, −3 and -4 which share a common general structure. The extracellular domain contains three immunoglobulin-like domains. The first and the second domains are separated by a stretch of ac...

the stoichiometric parameter namely “yield coefficient” associated with growth of certain organism can be determined by direct measurement and/or calculated indirectly. the focus of this paper was on the anoxic yield of heterotrophic organisms using ethanol as an external carbon source during the denitrification process. in the literature, it was observed that yield coefficients can vary for th...

Introduction The periods of lockdown during 2020 led to changes in daily occupations. As participation relies on dynamic interactions between the person, his/her occupations and environment, we wondered whether people from different generations shared same perception occupational disruptions lockdown. Methods We performed an online survey based Canadian Occupational Performance Measure (COPM) a...

In this paper, the possibility of mechanical coating of aluminum with either Ni or SiC using planetary ball mill was studied. The Al substrate was fixed inside of the vial lid of a planetary ball mill filled with milling balls and starting powder. The phase analysis and crystallite size measurement of the coatings were carried out using X-ray diffraction (XRD) method. Scanning electron micro...

conclusions according to the results of the present study, aerobic exercise at moderate intensity and proper time can be considered as a special treatment to prevent diabetes complications and related disorders, particularly obesity. objectives this study aimed to determine whether in patients with type 2 diabetes, substrate oxidation and energy expenditure were affected by the type of intensit...

The contribution of this paper is an experimentally veri ed real-time algorithm for combined probabilistic search and track using multiple unmanned aerial vehicles (UAVs). Distributed data fusion provides a framework for multiple sensors to search for a target and accurately estimate its position. Vision based sensing is employed, using xed downward-looking cameras. These sensors are modeled to...

In this paper the effect of plasma spray parameters, atomizing gas and substrate preheat temperature on microstructure and phase composition of YSZ coatings produced by SPPS process have been investigated. The experimental results showed that increasing the power of plasma, using hydrogen as the precursor atomizing gas and increasing substrate preheat temperature decrease the amount of non-pyro...
