This paper presents the simulation of auto-thermal ammonia synthesis reactor. Our target here is to estimate the optimal reactor length which will give the maximum profit from the ammonia reactor. There are many literatures which are interested in ammonia simulation in the past but all need some corrections due to either uncorrected model used or uncorrected algorithm. We used here the ODE45 so...

conclusions in the newly set up center similar to the older one, surgical treatment in our follow up duration was effective for reducing weight, body mass index reduction and achievement of success in biochemical markers on diabetics. results during follow up time after 276 days mean weight decreased from 118.7 ± 23.3 to 82.9 ± 15.7, p < 0.001 bmi also changed from 45.2 ± 1.8 to 32.2 ± 1.3, p <...

background: one of the most important activities in educational processes is evaluation of students. for evaluating the students’ professional performance, selecting an appropriate evaluation system is important. the aim of this study was to assess the clinical performance of medical interns and its affecting factors by mini-cex test. methods: this study was semi-experimental and mini-cex test ...

It was hypothesized that women of medium height would show a more secure, long-term mating pattern characterized by less jealousy, less intrasexual competition and a “slower” life history strategy. In three samples of female undergraduate students clear support was found for these hypotheses. In Study 1, among 120 participants, height was curvilinearly related to well-established measures of po...

We attempt to identify the different node hubs of a road network using PageRank for preparation for possible random terrorist attacks. The robustness of a road network against such attack is crucial to be studied because it may cripple its connectivity by simply shutting down these hubs. We show the important hubs in a road network based on network structure and propose a model for robustness a...

The use of mini-CT specimens for the fracture characterization structural steels is currently a topic great interest from both scientific and technical points view, mainly driven by needs requirements nuclear industry. In fact, long-term operation plants requires accurate reactor pressure vessel materials evaluation embrittlement caused neutron irradiation without applying excessive conservatis...

In this paper, we emphasized the dual application of Cu-modified vertically aligned TiO2 nanotube arrays as photocatalyst and a relative humidity sensor. The were obtained by anodization titanium layer prepared using radio frequency magnetron sputtering (RFMS) modified with different copper concentrations (0.5, 1, 1.5, 2 M) wet-impregnation method. sample M Cu(NO3)2 solution showed highest effi...

The activated sludge process is one of the most important parts of conventional wastewater treatment plants. Wastewater is treated biologically in activated sludge basins. Activated sludge can remove soluble contaminants, primarily organics compounds and nitrogen, from the wastewater stream. The activated sludge is a mixture of microorganisms, inorganic and organic compounds aggregated to flocs...
