Potential environmental benefits have been identified for the utilization of carbon dioxide (CO2) as a feedstock for polyurethanes (PUR). CO2 can be utilized in the PUR supply chain in a wide variety of ways ranging from direct CO2 utilization for polyols as a PUR precursor, to indirect CO2 utilization for basic chemicals in the PUR supply chain. In this paper, we present a systematic explorati...
abstract background: tibial torsion is one of the torsion density which rotating in the longitudes axis of the leg. to measure this deformity, different methods such as radiographic or clinical methods were presented and introduced. methods: in this quasi-experimental study, 30 male athletes were selected randomly. their tibial torsion angle was measured using ct scan, lavand, lokomso, foot p...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
introduction earth's atmosphere plays an important role in preventing the temperature decrease. one of the principal factors of environmental pollution and the main source of earth's climate and biodiversity changes is greenhouse gas emissions from various sources, particularly agricultural sector. agriculture sector is considered as a major source of greenhouse gas sequestration, including me...
in a 3×3 latin square design, 9 ok and multipaous lactating holstein cows averaging 76 ± 12 days in milk and 580±48 kg of body weight were assigned to three dietary treatments in 3 periods of 21 days. dietary treatments were 1) the control diet (without dried or ensiled tomato pulp), 2) diet with 8% dried tomato pulp (dm basis) and 3) diet with 8% ensiled tomato pulp silage (dm basis). tomato p...
carbon dioxide is a major greenhouse gas that contributes to the global warming by more than %60. absorption has been widely used to treat high concentrations of co2 in synthesis gas production, hydrogen manufacturing, and natural gas processing. the most well established method to capture co2 is its removal by absorption into amine solutions in the presence of activators. in this research, co2...
The emission of greenhouse gases (GHG) during feedlot manure composting reduces the agronomic value of the final compost and increases the greenhouse effect. A study was conducted to determine whether GHG emissions are affected by composting method. Feedlot cattle manure was composted with two aeration methods--passive (no turning) and active (turned six times). Carbon lost in the forms of CO2 ...
The role of carbon dioxide in global warming is one of the contemporary environmental issues and it is, therefore, necessary to have available technology to capture the released CO2 into the atmosphere. Amino acids have the same amine functionality as alkanolamines with similar behavior towards CO2 absorption. The solubility of carbon dioxide in potassium glycinate (KG) solutions with different...
