This project studies the effects of vehicle routing on pollution levels. We aim to develop queueing theory based mathematical models to analyse highway traffic flows and focus on focus on the capacity drop and shockwaves. Then we intend to use emission models and plume model to predict air pollution in a wider region. These predictions will be tested using remote sensing data and data from meas...

Iron is transported throughout the body as part of the transferrin protein and is stored as ferritin. The earliest stage of iron deficiency occurs when stores are depleted, characterized by a drop in serum ferritin levels and an increase in total iron binding capacity that refers to incomplete saturation of the transferrin molecule. Serum ferritin levels below 12 μg/l are associated with comple...

Radiant cooling systems (RCS) are gaining acceptance as a heating, ventilation, and air conditioning (HVAC) solution for achieving adequate thermal comfort maintaining acceptable indoor quality inside buildings. RCS well known their energy-saving potential; however, serious condensation problem hinders the growth of this technology. In order to prevent risk condensation, supply water temperatur...

not beginning or completing the vaccination schedule as recommended in the expanded programme on immunization is one of the major reasons for low immunization coverage. it should be studied in detail for remedial action, if the objectives of the epi in iran are to be achieved as stated. generally, lack of knowledge, lack of motivation and obstacles ore the basic categorical reasons for low cove...

Embryo cryopreservation is an indispensable technique in reproductive programs and in animal facilities where genetically modified mice are used extensively. Here we report the use of a vitrification spatula (VS) that can be readily homemade and has a large holding capacity to vitrify preimplantation mammalian embryos in a micro-drop employing ultra-rapid cooling in liquid nitrogen (LN2). Vitri...

Despite the growth in network capacity of wireless in-home networks, these networks often have insufficient capacity to support multiple simultaneous Audio/Video streams. Unpredictable behavior of these networks results in a drop of video quality for the end-user. A method for reducing the claim of an individual A/V stream on the network capacity is controlled frame dropping. However, controlle...

This study evaluated the efficacy of polyvinyl alcohol (PVA)‐coated powdered activated carbon particles as a biofiltration medium. This material exhibited excellent properties as a biofiltration medium with a water holding capacity of 1.39 g H2O/g‐dry PVA; wet porosity of 0.53; and significantly lower pressure drop than that of commonly reported biofilter media such as compost. Bench‐scale biof...

Capacity drop (CD) at overloaded bottlenecks is a puzzling traffic flow phenomenon with some internal and complicated mechanisms the microscopic level. not only important for theory modelling, but also significant control. A model evaluating control measures needs to be able reproduce capacity in order deliver reliable evaluation results. This paper delivers comprehensive overview on subject fr...

Industrial control valves often handle flows with very high pressure drops (conditions often referred to as severe service). In order to cope with such pressure drops, geometrically complex valve trims with many stages of pressure drops, are designed to prevent undesirable side effects such as cavitation etc. There are many different product designs for control valve trims produced by different...
