background: the poly-allyl diglycol carbonate (padc) detector is of particular interest for development of a fast neutron dosimeter. fast neutrons interact with the constituents of the cr-39 detector and produce h, c and o recoils, as well as (n, α) reaction. these neutron- induced charged particles contribute towards the response of cr-39 detectors. material and methods: electrochemical etchin...

cities are a focal point of energy consumption. accessibility to public services has a significant impact on the balance of public and private energy uses, which are two sectors that are directly affected by urban planning (the third is industrial). this paper establishes the relative magnitudes of service accessibility enhancement on urban energy efficiency in comparison to other factors, and ...

wheat is the dominant cereal crop constituting the first staple food in iran. this paper studies the energy consumption patterns and the relationship between energy inputs and yield for wheat production in iranian agriculture during the period 1986 – 2008. the results indicated that total energy inputs in irrigated and dryland wheat production increased from 29.01 and 9.81 gj ha-1 in 1986 to 44...

in this research, energetic andexergetic analysis of calcium oxide formation, co2 emissions, andenvironmental effects during the clinker production process in rotary kilnare investigated. first the energy and exergy analysis of rotary kiln were carried out according to the first and second law of thermodynamics based on dead state, respectively. consequently, the amount of co2 emissions associa...

Decisions can be taken to increase energy efficiency and to mitigate the emissions to the environment by examining the energy audit and greenhouse gas (GHG) emissions footprint of crop production in different ways and in different regions, with comparable principles. In this study, energy consumption and energy indices of tomatoes production in four regions of Iran including East Azerbaijan...

This paper covers the estimation of the average yearly production of an appropriate wind turbine for different locations in Iran. The effects of topography, the influence of obstacles such as buildings and shelters, the collective effects of the surrounding terrain, roughness classifications, and orographic elements such as hills, cliffs, etc., all have been included in the calculations. A full...

the exergy analysis is a proper method for performance evaluation of industrial systems. a generic and detailed analysis of the gpcss on the second gas pipeline of iran  is made by the means of exergy. the two main improvement measures of fuel pre-heating and steam injection technologies are presented for the current conventional stations. steady state equations regarding the second law of ther...
