in the management and evaluation of asthma, simple instruments for measurements of peak expiratory flow rate (pefr) are necessary. the aim of this study was to determine normal pefr of the healthy children in babol, iran. this study was randomly done on 1050 students (primary and secondary schools) in babol. mini-wright peak flow meter was used for measurement of pefr. the range of age, weight ...
soil detachment is known as an important process in soil erosion and its quantification is necessary to establish a basic understanding of erosion. this study was carried out to find the best flow erosivity indicator(s) for predicting detachment rate at low slopes. for this purpose, 12 experiments including 6 flow discharges (75, 100, 125, 150, 175 and 200 ml/s) and 2 slope gradients (1.5 and 2...
Variable rate application of fertilisers with traditional spinner-type spreaders is known to suffer from spread pattern uniformity variability as a function of application rate. To demonstrate this variability, simulations using models from the literature were carried out for two cases: (1) a dual disc spreader with segment-type feed gates; and (2) a single disc spreader with conical feed gates...
objective: the aim of the present study was to evaluate unstimulated salivary flow rate and oral symptoms in menopausal women. materials and methods: a total of 200 individuals including 100 women in their menopause (case group) and 100 men in the same age range (control group) participated in this analytic descriptive investigation. none of the patients were being treated for any systemic dise...
investigating nozzle’s orifice flow is challenging both experimentally and theoretically. this paper focuses on simulating flow inside diesel injector nozzle via ansys fluent v15. validation is performed with experimental results from winkhofler et al (2001). several important parameters such as mass flow rate, velocity profiles and pressure profiles are used for this validation. results includ...
Conductivity-based vacuum pan controllers dominate the Australian sugar industry. A new scheme, based on Brix control of the massecuite and mother molasses is proposed. Multi-loop control of the process is demonstrated, whereby the massecuite Brix is controlled by manipulating the liquor/A molasses feed rate to the pan and the mother molasses Brix is controlled by manipulating the steam flow ra...
Spray drying is a process widely used to produce fruit juice powders. In powders, it results with the good quality, low water activity, easier transport and storage. The physicochemical properties of powders produced by spray drying depend on the variables of process and/or operating parameters. In the present review, the principle of spray drying was described. In addition, some factors such a...
