We report on the preparation of the first complete extreme temperature Hall sensor. This means that the extreme-temperature magnetic sensitive semiconductor structure is built-in an extreme-temperature package especially designed for that purpose. The working temperature range of the sensor extends from -270 °C to +300 °C. The extreme-temperature Hall-sensor active element is a heavily n-doped ...

Due to easy availability of cheaper raw material and increase in new applications, the use of polyolefins in various industries is becoming a major priority. The Middle East region, on account of its vast oil and gas reserves has, in the last decade or so, been developing many new petrochemical complexes with their expansion into colossal polyolefin production capacities. The predictions are th...

as observed in some oil and gas countries, upstream service contracts, for instance buy-back contract in iran, would provide an appropriate environment for the development of oil and gas fields. however, certain cases, such as common structures and reservoirs, deep sea oil fields or second and third generations of an oil field may require more attractive contractual mechanisms in the eyes of io...

Background & Aim:  Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used in clinical medicine. The adverse effects they produce in the gastrointestinal tract however, often limit their utility. Oxidative stress has been shown to occur in the small intestine in response to the oral administration of indomethacin. In view of this, the effect of thyme essential oil, an agent with anti-o...

Nicotiana tabacum commonly known as Tobacco plant which has broad application over soap, paint and cigar industries was now investigated for biodiesel production. Nicotiana tabacum seeds were one of the prominent sources for non-edible oil. Oil from Tobacco seeds were expelled with Soxhlet extraction apparatus using n-hexane as extraction solvent. Two stage trans-esterification has been adopted...

Contaminant hydrology is the study of processes that affect both ground and surface water pollution. It draws on the principles of hydrology and chemistry. Contaminant hydrology and water quality research seeks to understand the role of soil properties and hydrologic processes on ground and surface water pollution and develop strategies to mitigate their impacts. Research is done at all scales ...

Future exploitation scheme of an oil reservoir in each cycle within its production life depends on the profitability of the current extraction scenario compared with predicted recoveries that acquire with applying other available methods. In fractured reservoirs appropriate time to pass from the gas injection process into chemical enhanced oil recovery (EOR) firmly depends on the oil extraction...

supply security of energy is one of the main challenges of industrialized countries in recent decades. also, it has been noted that in recent years other countries like new emergence asian countries and latin american countries, have understood the role and importance of energy. however, oil and gas have more importance for numerous reasons such as convenience availability, high thermal value a...
