Introduction: Nowadays, many modern industries require an environment with no contamination by particles and bacteria. An enclosed clean room environment is a place where parameters such as airborne particles, temperature, humidity, air pressure and air flow pattern is controlled. The aim of this study was to evaluate functional parameters of a clean room in a selected pharmaceutical industry....
بررسی تاثیر شیب اراضی و بار فشاری بر روی جریان آب در لوله نیمه اصلی و توزیع یکنواختی آب در سیستم های آبیاری قطره ای در مدیریت آبیاری و بهبود کارایی آب در مزرعه و تولید محصول مهم می باشد. این پژوهش به منظور تخمین تاثیر بار هیدرولیکی و شیب بر روی جریان آب در لوله نیمه اصلی و یکنواختی توزیع آب انجام گردید. در این تحقیق لوله های پلی اتیلن به قطرهای 50، 63 و 75 میلی متر در شیب های مختلف شامل 2/0، 6،...
In this work, sweeping gas membrane distillation (SGMD) process was used for concentrating of glucose syrup. The main questions in this work include: is SGMD process practical for concentrating of glucose solution prior the fermentation step in bioethanol process?. and are the commercially available hydrophobic membranes sufficient enough to develop the SGMD process in pilot scale for this issu...
In order to evaluate the growth indices of sugarcane in different irrigation systems, weed control treatments and correlative associations with quantitative and qualitative traits of sugarcane, an experiment was conducted as split plot based on randomized complete block design (RCBD) with three replications in 2020 at Sugarcane Development Research and Training Institute of Khuzestan, Ahwaz, Ir...
A study of the melt volume flow rate (MVR) and the melt flow rate (MFR) of kenaf fibre (KF) reinforced Floreon (FLO) and magnesium hydroxide (MH) biocomposites under different temperatures (160-180 °C) and weight loadings (2.16, 5, 10 kg) is presented in this paper. FLO has the lowest values of MFR and MVR. The increment of the melt flow properties (MVR and MFR) has been found for KF or MH inse...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
Aims of Study In the investigation of lower urinary tract symptoms many cases can be reliably assessed from a good history and a simple measurement of maximum flow rate (Q-max) alone. To obtain a reliable flow rate patients must void a reasonable volume, as flow is dependent on voided volume [1]. Clinical trials have demonstrated that the reliability of Qmax can be improved by bladder instillat...
the atmospheric pressure chemical vapor synthesis (apcvs) route is a process that can be used for the synthesis of doped-nanocrystalline powders with very small crystallite sizes having a narrow particle size distribution and high purity. in this study, apcvs technique was used to prepare boron-doped titania nanopowders. the effects of temperature, borate flow rate and water flow rate on the am...
