Ejectors have been widely used in many applications such as water desalination, steam turbine power generation, refrigeration systems, and chemical plants. The advantage of an ejector system lies in its extremely reliable and stable operation due to the complete absence of moving parts. However, the performance depends on a number of factors, among which the flow channel configuration/arrangeme...

Background: The advances in cytogenetic techniques during the last few years have permitted not only the study of large populations of wild and domestic animals, but also the detection of chromosome anomalies in embryos. Chromosomal abnormalities are the most common cause of embryonic and fetal mortality in mammals. Most reports of chromosome anomalies in parthenogenetic embryos describe numeri...

We consider two biological phenomena taking place at the air-water interface: the water lapping of felines and the water running of lizards. Although seemingly disparate motions, we show that they are intimately linked by their underlying hydrodynamics and belong to a broader class of processes called Froude mechanisms. We describe how both felines and lizards exploit inertia to defeat gravity,...

Abstract The Richards’ equation describes the flow phenomenon in unsaturated porous media and is essential to hydrology environmental science. This study evaluated numerical stability of two different forms equation. Sensitivity analyses were performed investigate control parameters results show that h -form has better applicability for calculating variable saturation flows than θ For equation,...

Most of the infrastructure investments and earthworks not requiring deep foundations are usually designed in vadose zone to avoid excessive groundwater-structure interactions. The mechanical behaviour soil material, under partially saturated conditions, is greatly influenced by pore-water tension, known as suction, characteristics Soil Water Retention Curve (SWRC). In present paper, SWRC a silt...
