Farmed and wild samples of two weight Cirrhinus viz., 501-900 g and 901-1300 g of Cirrhinus mrigala were collected from a Commercial Fish Farm and from river Chenab at Trimu Head Jhang, respectively. The extracted residues were pesticides analyzed through reverse phase high performance liquid chromatography (HPLC) technique. Endosulfan α, p, p’-DDT, methamidophos, carbofuran, diazinon, parathio...

water deficit, ultraviolet radiation and carbon dioxide enrichment are the most important environmental factors in global climate change. this research was conducted in tarbiat modares university, research greenhouse and the objective of that was to study the effects of three levels of carbon dioxide (500, 900 and 1300 ppm), uv-radiation (uv-a, b and c with intensity of 18, 25 and 40 µw.cm2 res...

In a business as usual scenario, atmospheric carbon dioxide concentration (CO2) could reach 950 parts per million (ppm) by 2100. Indoor CO2 concentrations will rise consequently, given its dependence on levels. If buildings are ventilated following current standards in 2100, indoor be over 1300 ppm, depending specific ventilation codes. Such exposure to have physiological and psychological effe...

OBJECTIVE The objective of this in vitro study was to compare the fluoride uptake into incipient enamel lesions of a novel 970 ppm F- ion SnF2 over-the-counter (OTC) gel (Enamelon Preventive Treatment Gel) and a novel 1150 ppm F- ion OTC toothpaste (Enamelon), each delivering amorphous calcium phosphate (ACP), to the uptake from two different prescription strength, 5000 ppm F- ion dentifrices c...

Al–TiC nanocomposite materials have been prepared by a new in situ synthesizing technique. A mixture of aluminum, titanium, and graphite has been prepared using ball milling technique and then melted in a high frequency induction heat furnace (HFIHF) at different sintering temperatures, namely 900, 1100, and 1300 °C. The effect of sintering temperature on the corrosion of the Al–TiC composite i...

A comparison of force measurements performed at the National Institute of Standards and Technology, USA, and at the Physikalisch-Technische Bundesanstalt, Germany is reported. The focus of the study was the intercomparison of the forces realized by the two Institutes rather than the measurement process. The transfer standards used in the comparison consisted of force transducers and associated ...

Larvicidal activity of acetone and petroleum ether extracts of four plants Murraya koenigii, Coriandrum sativum, Ferula asafoetida, Trigonella foenum graceum and synthetic larvicides Fenthion and Temephos used alone and in combination was carried out against A. aegypti larvae under laboratory conditions. Optimum values were found out by using different concentrations of each plant (ranged 25 pp...

We report improved sensitivity to NO, NO₂ and NH₃ gas with specially-designed AlGaN/GaN high electron mobility transistors (HEMT) that are suitable for operation in the harsh environment of diesel exhaust systems. The gate of the HEMT device is functionalized using a Pt catalyst for gas detection. We found that the performance of the sensors is enhanced at a temperature of 600 °C, and the measu...

The object of this study is the formation intermetallic phases (IMPhs) in heat-affected zone (HAZ) joints steel–titanium bimetal plates produced by arc welding. A titanium layer (2 mm) was welded plasma method (PAW), a barrier Cusi3Mn1 bronze deposited on it TIG method, first steel CMT, and Puls-MAG used for filling groove. Here, heating solid phase takes place HAZ, which may lead to undesirabl...
