A completed study of a solar hot water heating system installed in a school showed an annual average efficiency of 15%, the low efficiency largely caused by the unfavourable pattern of use in schools. Field studies, in 80 existing and 12 new houses, of a simple domestic hot water system have been initiated to ascertain the influence of the occupants on the actual performance of solar collector systems. The development of testing methods of solar collectors and solar water heating systems is being undertaken in close collaboration with the B.S.I. and the E.E.C. Solar space heating is being investigated in two experimental low energy house laboratories, one using conventional solar collectors with interseasonal heat storage and the other a heat pump with an air solar collector. Studies of the cost-effectiveness of solar collector applications to buildings in the U.K. show that they are far less cost-effective than other means of conserving energy in buildings.

Acute kidney injury (AKI) is a risk factor for increased mortality in critically ill patients. Sustained low efficiency dialysis (SLED) is a new approach in renal replacement therapy (RRT) and it combines the advantages of continuous renal replacement therapy (CRRT) and intermittent haemodialysis (HD). The study was aimed to evaluate the outcome of the hae-modynamically unstable patients with AKI in Bangladesh who were treated with SLED. So far this is the first reported study on SLED in intensive care unit (ICU) in Bangladesh. This quasi-experimental study was conducted in a 10-bed adult ICU of a tertiary care hospital in Bangladesh from June 2012 to May 2013. A total of 153 sessions of SLED were performed on 43 AKI patients. Mean age of the patients was 60.12 ± 15.57 years with male preponder-ance (67.4% were male). Mean APACHE II score was 26.88 ± 6.25. Fourteen patients (32.55%) had de novo AKI. Twenty nine patients (67.4%) had chronic kidney disease (CKD) with baseline mean serum creatinine 2.56 mg/dl, but did not require any RRT before admis-sion in ICU. After giving SLED, AKI of the study patients were completely resolved in 27.9%. Some forty two percent patients became dialysis dependant and 30.23% patients died. Patients who had AKI on CKD became dialysis dependant more often than the patients with de novo AKI (p <0.01). Mortality rate was significantly higher in patients who were on inotrope support (p= 0.017). Otherwise, there was no relation of 28 day mortality with age, prior renal function and mechanical ventilator requirement (p>0.05). Thus, SLED is an excellent renal replacement therapy for the haemodynamically unstable AKI patients of ICU. It is also cost-effective compared to CRRT.

Cellulosic biofuels can be used to replace traditional liquid transportation fuels. Cellulosic biomass is feedstock in manufacturing of cellulosic biofuels. However, the low density of cellulosic biomass feedstock hinders large-scale and cost-effective manufacturing of cellulosic biofuels. Another bottleneck factor in manufacturing of cellulosic biofuels is the low efficiency of the enzymatic hydrolysis of cellulosic biomass materials resulting in a low sugar yield. Ultrasonic vibration-assisted (UV-A) pelleting can increase the density of cellulosic biomass feedstocks via combined effects of mechanical compression and ultrasonic vibration of the tool on the cellulosic biomass. Meanwhile ultrasonic vibration may act as a beneficial pretreatment for enzymatic hydrolysis, which can possibly increase the efficiency of hydrolysis and obtain a higher sugar yield. The pressure and the ultrasonic power are important parameters in UV-A pelleting. Their effects on pellet quality (density, durability, and stability) and sugar yield (after hydrolysis) are experimentally investigated.

Currently, the agro-industrial complex is a set of different branches of the agricultural system that are aimed at producing or processing agricultural raw materials and obtaining various types of finished products from it.The purpose of this study is to characterize the current state and prospects for the development of the agroindustrial complex of the region.Methodology. Methods of the research on the implementation of tasks are considered using horizontal analysis methods, tabular and graphical data display, data comparison (comparison method), to solve specific problems of the regional agro-industrial complex.The originality of the study is the use of a mechanism to substantiate strengths with positive opportunities for the development of the agro-industrial complex of the Turkestan region, which contribute to the creation of conditions for the cost-effective functioning of agro-industrial enterprises in the region.Findings. The article analyzed the statistical data of the agro-industrial complex of the Turkestan region, identified vulnerable sectors of agriculture in the region. Despite available resources and capacity, challenges are being identified, such as:– Low level of competitiveness of products and profitability of agro-industrial enterprises;– Low efficiency of smallholders;– Poorly oriented research on the needs of agricultural production, etc., which needs to be addressed in order to stabilize and improve the well-being of the agro-industrial sector and, as a result, the well-being of the region.

Framework Conditions

This work compares biomass gasification and conventional direct combustion in steam boilers for producing power in the context of Brazilian sugar cane mills. The objective of this technical report is to show that gasification could be a more attractive way to convert biomass in energy, compared to using steam boilers, which in some cases can show a low efficiency.  The idea is to use the gasifiers in sugarcane mills that have low pressure boilers (21 to 42 kgf/cm2) that are currently dedicated only to generate steam or electrical power for the mill own energy consumption. The results shows that gasification could be a cost-effective alternative for power production in Brazilian sugar cane plants with some additional advantages like the bagasse usage between the season and off-season periods to maintain a constant power generation throughout the entire year, higher energy availability and efficiency. However, nowadays in Brazil the economic advantage of gasification depends highly on political support and reliable long-term stable political framework conditions with an enough timeframe for the development, construction and operation of biomass gasification plants.
