The repellent action of neem oil was evaluated against sand flies under laboratory and field conditions. Concentrations of 2% neem oil mixed in coconut or mustard oil provided 100% protection against Phlebotomus argentipes throughout the night under field conditions; against Phlebotomus papatasi it repelled sand flies for about 7 h in the laboratory. Neem oil is an indigenous product and a low-...

Electroporation is the most widely used transfection method for delivery of cell-impermeable molecules into cells. We developed a novel gene transfection method, water-in-oil (W/O) droplet electroporation, using dielectric oil and an aqueous droplet containing mammalian cells and transgene DNA. When a liquid droplet suspended between a pair of electrodes in dielectric oil is exposed to a DC ele...

Nuclear Geophysics is essential to the oil, gas and uranium industries. The initial development of nuclear geophysics was focused on developing techniques needed by the oil industry. Developments in nuclear physics and computational analysis were immediately used this field. Today, techniques developed in nuclear geophysics are also used by the coal and metalliferous mining industries and contr...

Water flooding is a common technology of enhanced oil recovery and has been widely used to the world's oil fields. But it is difficult to maintain a uniform displacement of water, which causes the ineffective circulation of injected water. Therefore, the real-time dynamic control strategy is studied to work out development plans scientifically and make better economic profits in this paper. The...

The development of neural network that could be used for the control of an industrial process is discussed. Field data from a working distillation column or fractionator of crude oil refinery in Nigeria was used for the development and testing the effectiveness of the controller. The developed controller performed optimally when compared with the installed distributed control system based on pr...

In order to find out the advantages and disadvantages of various development methods of coal bed gas, the experimental block provided by the field is studied, the component calculation model is established by CMG numerical simulation software on the basis of fine geologic modeling. Four development schemes are designed which are depleted development, development of hydraulic fracturing, develop...

background and aim: tanacetum parthenium l. is herbaceous perennial medicinal plant belonging to the asteraceae family. feverfew is used as an analgesic, housing, fever-lowering, anti-rheumatism and migraines in traditional medicine. the most important active ingredient of the herb is essential oil. variation on genetic and environmental conditions play a major role in the growth, development, ...

Abstract:Non-oil exports are increased in the measures taken, to reduce Iran's dependence on oil revenues. Creating new business areas in different sectors and unused capacities are fac-tors that make it imperative to pay attention to the development of non-oil exports. Ex-port growth is the key to economic recovery for governments. Among non-oil exports, in many countries of the world th...
