conclusions applying a simple and brief scale that incorporates the different dimensions of hiv transmission risk may provide policymakers and harm reductionists with a better understanding of hiv transmission in this key group and may be advantageous for evaluating intervention programs. results we extracted 7 items based on first factor, which were accounted for 21% of the variations. the fin...
the asymptotic behaviour of the sequence with general term $p_n=(varphi(1)+varphi(2)+cdots+varphi(n))/(1+2+cdots+n)$, is studied which appears in the studying of coprime integers, and an explicit bound for the difference $p_n-6/pi^2$ is found.
in a study to determine the influence of sexual behaviour to hiv contamination, in 22 patients infected with aids in iran, this survey was conducted. the subjects were 21 male and one female. one of the male patients was from uganda, another was an intravenous drug addict, and one patient has been abroad for sometime. one of the patients had been abroad and received blood there, and other patie...
in this study, the four cr-mn-(ni-free) austenitic steels were fabricated by vacuum induction furnace. then plates with 10 mm thickness were fabricated by hot-rolling. corrosion behaviour of the four cr-mn steels in 0.1 m h2so4 solution was investigated using by open-circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy (eis). the results indicated that the...
in this paper, the effects of roll center height of mcpherson suspension mechanism on dynamic behaviour of a vehicle is studied first and then the optimum location of roll center of this suspension system is determined for a conceptual class a vehicle. adams/car software was used for analysis of vehicle dynamic behaviour in different positions of suspension roll center, then optimization proces...
conclusions the effectiveness of nursing education on self-care behaviour of hf patients was clearly demonstrated. methodological differences in development and implementation of education programs, made the comparison between the results of the studies difficult. results the findings of the reviewed studies showed that self-care behaviour of patients who received nursing education improved sig...
the present paper is devoted to a new critical state based plasticity model able to predict drained and undrained behaviour of granular material. it incorporates a bounding surface plasticity model describing in multilaminate framework to capitalize on advantages of this mathematical framework. most of the models developed using stress/strain invariants are not capable of identifying the parame...
One of the best and the most active ways for surveying thermal behaviour of materials is using differential scanning calorimetry. In this paper, the authors have studied thermal behaviour for Schiff base ligand and their synthesized Cobalt, Nickel complexes. In this method, the sample is opposed to a controlled temperature change and its physical properties. Here we studied melting point and Tg...
Food anticipatory activity (FAA) was assessed in rainbow trout ( Oncorhynchus mykiss ) in two small raceways using demand-feeding (T2) and hand-feeding (t2). The fish of both raceways were subjected to restricted feeding (RF) at two times in two places and the fish distribution and/or trigger actuation, total agonistic behaviour between fish, and swimming speed were measured. Food anticipatory ...
At the first stage Fe3O4 and Fe nanoparticles were synthesized via a simple hydrothermal method. Then silver nanoparticles and Fe-Ag nanocomposites were synthesized in the presence of NaBH4. The prepared products were characterized by X-ray diffraction pattern, scanning electron microscopy, and Fourier transform infrared spectroscopy. Vibrating Sample magnetometer illustrated that Fe nanopartic...
