Objective estimates of activity patterns and energy expenditure (EE) are important for the measurement of energy balance. The Intelligent Device for Energy Expenditure and Activity (IDEEA) can estimate EE from the thirty-five postures and activities it can identify and record. The present study evaluated the IDEEA system's estimation of EE using whole-body indirect calorimetry over 24 h, and in...

Abstract This work presents the results of a numerical study working processes burning lignite in vortex furnace with swirling countercurrent flows. The computer simulation moisture content 30%, an ash 20% and 35% higher calorific value Qрв = 13.9 MJ/kg 9.7 MJ/kg, respectively are given. fields temperature distribution, gas velocity particle trajectory volume at outlet determined. values flow n...

The need for plastic corresponds with the annual rise in population. Meanwhile, waste that is improperly managed can negatively influence environment. Therefore, a more promising alternative recycling process needed to convert this into oil by cracking, and possibly assisted adding empty palm bunches. This study examines how modifications ratio of bunches Polypropylene (PP) percent liquid produ...

During the past few years, modeling in agriculture has attracted considerable attention. New modeling methods including neural networks are employed in various industries, and it is necessary that their use in agriculture be also considered. This research addressed the trend of energy use in broiler farms in Alborz Province and sought to model the trend of energy consumption and production in t...

The aims of this study were to evaluate the energy consumption and its modeling in industrial milk production units using data envelopment analysis (DEA) approach and sensitivity analysis. Data were collected from 44 industrial milk production units in Guilan province of Iran with face to face questionnaire method during 2012-2013. Inputs included animal feed, fossil fuels, electricity, machine...

The aim of study was to determine the energy requirements for maintenance and growth of forty-one Saanen, intact male kids with initial body weight (BW) of 5.12±0.19 kg. The baseline (BL) group consisted of eight kids averaging 5.46±0.18 kg BW. An intermediate group consisted of six kids, fed for ad libitum intake, that were slaughtered when they reached an average BW of 12.9±0.29 kg. The remai...

Bu çalışmada, Türkiye’nin Karaman ili merkeze bağlı Taşkale köyünde mısır tarımında enerji bilançosunun belirlenmesi amaçlanmıştır. Denemeler Taşkale’de bulunan bir üreticisinin işletmesinde gerçekleştirilmiştir. Denemelerde, girdileri; insan işgücü enerjisi, makine dizel yakıt kimyasal gübre tohumluğun enerjisi ve sulama suyunun enerjileri olarak sınıflandırılmıştır. Üretim süresince bunların ...

Energy expenditure was estimated using the doubly-labelled water (DLW) method in summer in five free-living adult, non-pregnant, non-lactating, red deer (Cervus elaphus) hinds (weight 107.3 (SE 0.9) kg; age 6 (SE 1) years) on lowland pasture under typical farming conditions. Climatic conditions were monitored throughout the experiment. Errors due to 2H losses in CH4 and faeces were calculated f...

El principal objetivo de esta investigación es caracterizar la gasificación hojas y tallos obtenidos como biomasa residual en el cultivo palma aceite utilizando aire agente gasificante. Se desarrolla una experimentación tipo barrido se utiliza un reactor caída libre flujo descendente. A 800°C relación equivalencia (ER) 0.24, los resultados muestran para las rendimiento 1.85 Nm3 gas/kg sec...

Sixty growing 3/4 Boer x 1/4 Spanish (BS) and Spanish (SP) wethers were used to determine influences of diet and breed on growth and body composition. A pelleted 50% concentrate diet (CD) and a diet based on grass hay (HD) were fed for ad libitum intake. Six wethers of each breed were slaughtered at 0 wk (total of 12). Six wethers of each diet-breed combination were slaughtered at 14 and 28 wk ...
