This work first-time addresses the synergetic hydrothermal co-valorisation of almond hulls (an unavoidable food waste) and FFP2 face masks (a common plastic material) using seawater sustainable reaction medium). The effects feedstock composition (each material alone all possible binary combinations) medium (deionised water, mixtures) have been evaluated at 350 °C 170 bar over a wide range times...

Abstract Spent coffee grounds (SCGs) have been extensively investigated as a feedstock to produce fuels, specialty chemicals and materials. Whilst few reports used cascade processes generate several products from SCG, this work takes the novel approach of using integrated subcritical water extraction (SWE) hydrothermal carbonisation (HTC) derive three products: bioactive extract, protein isolat...

In breeding hind systems, summer is often a period when feed quality and quantity may compromise lactation in the hind and growth of the calf. The growth and feed intake of calves and hinds offered the leaf turnip Pasja were compared to those on a perennial pasture. Calves consumed 1.0 kg forage DM/head/d on pasture and 0.77 kg DM/d on Pasja. The higher digestibility of Pasja meant that the met...

this study was conducted to determine a relationship between energy input and yield in greenhouse basil production in esfahan province, iran. data were collected from 26 greenhouse basil producers through a face-to-face questionnaire. the data collected belonged to the production period of 2009–2010 with the following results obtained. a total energy input of 236,057 mj ha-1 was estimated to be...

Whole-crop wheat treated with 40 kg urea/t/DM was examined in two experiments as the sole forage offered ad libitum. The objective was to evaluate the nutritive value of the forage, and the response in milk production to energy and protein supplements. In Experiment 1, 12 Holstein Friesian lactating cows in three 4 4 Latin squares were offered four concentrates, AÐ6 kg/day of 208 g CP kg/DM, BÐ...

The effect of body fatness on the fasting heat production and energetic efficiency of adult sheep was studied. Energy balance and heat production were determined in adult wether sheep at three fatness levels given a diet of grass hay and maize at four feeding levels, including fasting, in open-circuit respiration chambers. The sheep weighted approximately 60 kg at the start and were fed over a ...

The direct methanol fuel cell (DMFC) is considered a viable power production technology for portable electronics equipment (10’s-100’s watts) and transportation vehicles (10’s-100’s kilowatts). Since methanol is relatively inexpensive and a reformer or other fuel processing equipment is not required for the DMFC, this power system has the potential to be low cost, compact, reliable and fuel eff...

A calorific value of various biomass samples (waste of wood, paper, textile, agricultural plants) and liquid biofuels (bioethanol, biodiesel) has been studied in this paper. In addition, a specific combustion heat of the biomass samples was calculated, which almost was coincided with the experimental heating value. It was established that the specific combustion heat of the investigated solid p...

Abstract The T6 Stalker Tunnel is a multi-mode, high-enthalpy, transient ground test facility. It the first of its type in UK. facility combines original free-piston driver from T3 Shock with modified barrels Oxford Gun Tunnel. Depending on requirements, it can operate as shock tube, reflected tunnel or expansion tube. Commissioning tests are discussed, including development four baseline condi...

The study aims to investigate the influence of supplementation hydroxy methionine analogues (HMA) and vegetable oils (VO) on testosterone hormone levels physiological profile blood plasma fattening Bali cattle. A randomized block design with four treatments tests was used in study. Sixteen male cattle a body weight range 78-183 kg CV 25.33% were used. ration containeds 18% protein ME = 16 MJ/kg...
