The influence of reactor wall conditions on the characteristics of high density fluorocarbon plasma etch processes has been studied. Results obtained during the etching of oxide, nitride, and silicon in an inductively coupled plasma source fed with various feedgases, such as CHF3 , C3F6 , and C3F6/H2 , indicate that the reactor wall temperature is an important parameter in the etch process. Ade...

The significant consumption of gas in the World results in the emission of greenhouse gases into atmosphere. Abadan refinery has always been the biggest and oldest oil refinery in the Middle East and has a variety of refined products. After six months of collecting data about pollutant concentration emitted from a stack of old furnaces of units 75 and new unit 200, the emission factor of the po...

Estuarine circulation is a vertical that develops along the salinity gradient in estuaries and nearshore coastal waters. Fresher, therefore less-dense, water flows out of estuary surface layer, while deeper inflow brings from open sea into estuary. This study uses 7 years situ current measurements hydrographic surveys to verify this has two modes: deep intrudes seabed, shallow-inflow penetrates...

The signal of a microwave radiometer observing a land surface from space is composed of surface and atmospheric contributions, both of which depend on the relief. For proper interpretation of the data these effects should be quantified and, if necessary, taken into account. Relief effects are twofold: First, the path through the atmosphere between the surface and the sensor depends on the altit...

Heat and mass transfer phenomena that take place during frying cause physicochemical changes, which affect the colour and surface of the fried products. The effect of frying temperature on the colour changes and heat transfer during deep fat frying of garlic has been investigated. The colour scale parameters redness (a*), yellowness (b*) and lightness (L*), and color change intensity (∆E) were ...

The objective of this work was to study the influence palm oil on VOCs emitted during heat treatment Afromosia (Pericopsis Elata Van Meeuwen) and Newtonia (Newtonia paucijuga Harms) wood by comparing under air. Two batches Afrormosia samples were heated air at temperatures 160 °C, 180 200 °C for 2 h. Then, collected Solid Phase Micro Extraction (SPME) measured using a Gas Chromatograph Mass Spe...
