| This short paper investigates the cointegration and causality link between energy consumption and agricultural, non-agricultural outputs (manufacturing sector and services sector) and overall gross domestic product in Tunisia for 1971-2003 period. Empirical results suggest that there is only unidirectional causality running from agricultural and non-agricultural sectors to energy consumption as well as from overall GDP growth to energy consumption. This unidirectional causality signifies a less energy dependent economy and suggests that it is sectoral growth that drives the energy consumption in Tunisia and not vice versa. Empirical results suggest also that Tunisian agricultural sector growth does not depend on energy, and high consumption of energy do... |

| In view of the complexity and non-linearity of energy consumption system and the status quo of the development of energy in Qinghai province, the relations between energy consumption and industrial structure is analyzed by using the quantitative analysis of grey relation degree by using the grey system theory. The relevancy degree among the primary industry, the secondary industry and the tertiary industry and living energy consumption are obtained, and then the trend of energy consumption in the following several years can be predicted. The results show that the secondary industry has the largest relevancy degree to the total energy consumption. In the end, according to the results of the research, several suggestions on how to saving energy are put... |

| In order to study the effect of conservative tillage on a number of physical properties of soil and the yield of rainfed wheat, an experiment in form of a randomized complete block design (RCBD) with three replications was conducted in a field in Aliabad County, Iran. The study treatments included: T1) Conventional method, T2) Combined moldboard plow method, T3) Chisel-packer method, and T4) Direct planting method. During early October, the study soil was prepared based on these treatments in a field which was used for rainfed wheat farming in the the previous year. The apparent specific gravity of soil, weighted mean diameter (WMD) of soil aggregates, soil mechanical resistance, and soil permeability were measured. Data were analyzed in MSTAT-C.... |

| Abstract: The effect of air temperature (50°C, 60°C, 70°C, 80°C and 90°C) and pre-treatments (steam, water palm oil-water, groundnut oil-water blanching) on the drying characteristics and quality of bell pepper was investigated. The results were fitted to six thin-layer drying models and Parabolic model gave the best fit. The pretreated samples dried faster than untreated samples and had lower values of total energy needed and specific energy requirement. The ascorbic acid content, color and rehydration index varied from 129.1 to 316.8 mg/100 g dry matter, 0.1 to 0.9, 22 to 33 mL and pretreated dried pepper generally had higher values than untreated samples. Keywords: modeling, energy consumption, Rehydration index, color, pepper |

| This study applies panel data techniques to investigate the long-run relationship between energy consumption and GDP for a panel of 19 African countries (COMESA) based on annual data for the period 1980-2005. In the first step, we examine the degree of integration between GDP and energy consumption by employing three panel unit root tests and find that the variables are integrated of order one. In the second step, we investigate the long-run relationship between energy consumption and GDP. Results overwhelming show that GDP and energy consumption move together in the long-run. In the third step, we estimate the long-run relationship and test for causality using panel-based error correction models. The results indicate that long-run and short-run causality... |

| This paper aims to analyse the direct energy utilization in the processing of cocoa beans into powder using energy from the national grid and diesel engine in some cocoa processing factories located in South-western Nigeria. Energy consumption in the processing of cocoa beans into powder was evaluated for the eight major unit operations that cocoa processing entails, namely: cleaning, roasting, winnowing, milling, alkalizing, pressing, butter packing and grinding/sieving. The data obtained were imputed into existing energy equation to estimate the energy requirement for each of the eight unit operations. The results show that total energy expenditure in the processing of raw cocoa bean into powder were 1.815 and 2.384 MJ/Kg using national grid (PHCN) and... |

| This study was conducted to evaluate and compare the behavior of the heating inside poultry shed through gas hood and underfloor heating. The experiment was conducted in poultry shed belonging to the Federal Institute of Education, Science and Technology of Triângulo Mineiro Region, Uberlândia city  state of Minas Gerais (MG), Brazil. The dimensions of the shed are 24 meters long and 9.6 meters wide and with a ceiling height of 3.2 meters. The temperature was measured with an optical thermometer of Minipa brand, MT 350 model. It was used, to the analysis of temperature behavior, the public domain software FEMM 4.2, which uses finite elements techniques, with data collected from two lots. Underfloor heating is made using hot water flowing through a... |

| ABSTRACT This study aimed to evaluate the effects of using infrared radiation in the hot-air drying of Moringa oleifera grains on the inner dryer and grain temperatures, energy consumption, and grain quality. An experiment was conducted in a factorial scheme in 2013 to identify the optimum values of the air temperature (30 to 58 ºC) and infrared radiation application time (2.0 to 4.8 min) on moisture content, drying time, drying rate, inner dryer air temperature, grain temperature, energy consumption and quality of grains used as a natural coagulant for water treatment. The results obtained were moisture content from 4.40 to 4.76% wet basis; drying time from 0.50 to 2.00 h; drying rates from 0.70 × 10-3 to 2.05 × 10-3 kgwater kg-1 dry matter min-1; inner... |

| This paper estimates the causal relationships between energy consumption and income for India, Indonesia, the Philippines and Thailand, using cointegration and error-correction modelling techniques. The results indicate that, in the short-run, unidirectional Granger causality runs from energy to income for India and Indonesia, while bidirectional Granger causality runs from energy to income for Thailand and the Philippines. In the case of Thailand and the Philippines, energy, income and prices are mutually causal. The study results do not support the view that energy and income are neutral with respect to each other, with the exception of Indonesia where neutrality is observed in the short-run. |
