water distribution method based on the type of water conduits can be divided into two groups, namely, open and closed systems, while on the basis of the energy of the water flow, the two groups are gravity flow and pressurized flow. open channel type conveyance and distribution is achieved by gravity and includes channels made by embankment construction, excavation, or construction of prefabric...

Depletion of water supplies for potable and irrigation use is a major problem in the rural wadi valleys of Saudi Arabia and other areas of the Middle East and North Africa. An economic analysis of supplying these villages with either desalinated seawater or treated wastewater conveyed via a managed aquifer recharge (MAR) system was conducted. In many cases, there are no local sources of water s...

Recent advancements in the inhalable, injectables, transdermal, nasal and other routes of administration, the unavoidable truth is that oral drug administration has been the preferred route for the drug delivery. There are sure components like poor medication solvency or retention, quick digestion system, high change in the medication plasma level and variability in quick and encouraged impact,...

In this paper we present a distributed and modular system to convey small and fragile objects. This is done by attaching similar modular blocks together to form a larger conveyance surface. Similar to other networked control systems, each block is composed of several sensors, actuators and communication infrastructure. Control of a levitating object should be done distributed and real-time. We ...

We performed an epidemiological investigation of subjects with premenstrual dysphoric disorder (PMDD) to identify the clinical distribution of the major syndromes and symptoms. The pathogenesis of PMDD mainly involves the dysfunction of liver conveyance and dispersion. Excessive liver conveyance and dispersion are associated with liver-qi invasion syndrome, while insufficient liver conveyance a...

The authors have developed a power-assisted system aimed at solving the following problems in a factory; i.e., a common conveyance system such as an overhead crane using pushbutton control can pose difficulties for the operator in positioning an object due to the object’s vibration. As well, workers often suffer physically from directly moving or lifting heavy objects. In light of this, our pro...
