The aim of this study was to determine the occurrence of enterotoxigenic and enteroaggregative Escherichia coli strains and antibiotic resistance of the isolates in raw milk and unpasteurized cheese. Out of 200 samples of raw milk and 50 samples of unpasteurized cheeses, 96 and 24 strains of E. coli were isolated, respectively. Polymerase chain reaction (PCR) was used to detec...

ABSTRACT. Aerospace and automotive industries employ Ti4Al4Mo2Sn material in many applications due to its properties of better strength weight ratio high corrosion resistance. finds itself difficult cut materials physical chemical is prone more heat generation during machining. The affects the machined surface quality other related properties. In this investigation, thermal conductivity stabili...

Fig. 1. The original purpose of our paper (Wei and Sandwell, 2006) was to provide an estimate of the global Cenozoic heat flow that was largely independent of the sometimesbiased conductive heat flow measurements (Hofmeister and Criss, 2005). The increasing seafloor depth with increasing age is one of the most obvious signals of global plate tectonics. Global mantle convection with thin surface...

thermal conductivity is an important property of juices in the prediction of heat- and mass-transfer coefficients and in the design of heat- and mass-transfer equipment for the fruit juice industry. an artificial neural network (ann) was developed to predict thermal conductivity of pear juice. temperature and concentration were input variables. thermal conductivity of juices was outputs. the op...

In most production-inventory systems, the products are transferred from the production centre to the inventory (warehouse) in subbatchs rather than one at a time. In this paper, mathematical models of such systems for both deterministic and stochastic cases of demand are developed and analysed. Comparison of these new models with the EBQ model shows a considerable loss when applying the ru...

In this work, conduction-convection heat transfer through a straight fin, property distribution due to convection-diffusion, and conduction heat transfer through a slab with temperature dependent thermal conductivity are evaluated using Adomian decomposition method. The results are compared with numerical and exact solutions. It is shown that the numerical simulation has some limitations and ma...

This paper shows how “multiple resonance networks” of any order an with several structures can be systematically designed using standard passive filter design techniques. These networks are composed of capacitors, inductors, transformers, and a switch, and have the property of transferring completely energy initially put in one capacitor, insulated by the switch, to another capacitor in the cir...

BACKGROUND In comparison to short-term gonad heat exposure, little is known about the molecular mechanisms that regulate testicular steroidogenesis during long-term whole body heat acclimation. MATERIAL AND METHODS Testicular slices from neonatal (NHA) and adult (AHA) heat-acclimated Wistar rats were analysed in vitro to assess the mRNA expression and enzymatic activity of steroidogenic enzym...

Al-0.9Si-0.6Mg (wt%) alloy conductive wires were designed and produced by continuous rheo-extrusion process. The effects of different heat treatment on microstructure, mechanical and conductive properties of the wires were studied. Results show that, after T6 heat treatment, conductive property of the alloy increased while elongation decreased with the higher aging temperature and longer aging ...
