A new developed dustfall collector has been investigated which collects airborne dust by sedimentation. The dustfall collector was placed at least 1.5 m above the floor. It was made of cardboard and the collecting surface was covered with aluminium foil; a chicken wire covered the box. After 140 days the dust was collected using the VacuMark sampler. Bioaerosols were sampled three times during ...

The antibacterial activity of propolis produced throughout the year by different methods of collection (‘intelligent’ collector of propolis ICP; plastic screen PC; conventional scraping CS) on Staphylococcos aureus and Escherichia coli is investigated. Fifteen beehives (five per collector) of Africanized Apis mellifera were used. Monthly produced propolis, with the same collection technique, wa...

Solar energy is used for solar water heater in domestic and industrial purpose. Pulsating heat pipe is a fast responding, flexible and high performance thermal conducting device. The CLPHP system described in this study relies on the natural forces of gravity and capillary action and does not require an external power source. The flat plate collector consisted of a 2 mm thick sheet of Aluminum ...

This was done on basis substantiating connection all system taking into account influence work efficiency effectiveness regulating water regime drained lands. existence structure hierarchical hydraulic relationship between parameters soi...

1 Recently, Hadoop, an open source implementation of MapReduce, has become very popular due to its characteristics such as simple programming syntax, and its support for distributed computing and fault tolerance. Although Hadoop is able to automatically reschedule failed tasks, it is powerless to deal with tasks with poor performance. Managing such tasks is vital as they lower the whole job's p...

This paper reports the thermal performance of a new cylindrical solar collector based on an experimental investigation with this difference that instead of the collector tube with absorbent coating, coil into a spiral copper tube is placed in the center of the collector. The spiral shape of the tube, heat transfer without disruption or increase the heat transfer area, is increasing. In this cas...

Patients with an accessory kidney are characterized by an excessive number of kidneys. The ureter of the accessory kidney either drains separately into the bladder or merges with the ureter of the main kidney. In our case, interestingly, the ureter of the left main kidney drained directly into the accessory kidney and the ureter of the latter was the common drainage route for both. The drainage...
