Abstract:The paper presents a computer modelling and experimental validation for the thermodynamic performance of parabolic troughsolar collectors (PTSC) used in a micro-combined cooling,e heating and power (mCCHP) system. The thermal efficiency, fluidoutlet temperature, heat gain and heat and optical losses of the collector are calculated depending on the collector geometry,optical properties, fluid properties, fluid inlet temperature and flow rate, solar insolation, wind speed and ambient temp...

Abstract:Alkaline protease from Conidiobolus coronatus which is optimally active at pH 10 and 40°C finds application in leather and detergent industries as well as for recovery of silver from waste photographic films. The protease was immobilized in Ca-alginate, polyacrylamide gel and alkali treated waste fungal biomass (ATWFB). ATWFB was found to be most suitable among the matrices tested. Glutaraldehyde marginally increased the binding to ATWFB. Binding of protease to ATWFB seems to be through...

AbstractThis paper presents research into conceptualisation, design and implementation of an innovative web-based virtual environmentfor flood information sharing and dissemination. A system intended to be used by flood management authorities and potentiallyaffectedcitizens is demonstrated. Latest technological advances for collection, archiving and sharing of environmental data usingweb-based Spatial Data Infrastructure (SDI) are used for system implementation. Flood-related data and models are...

AbstractIn recent years non-metric digital cameras have known a great development, being used in wide applications, such as: real timemonitoring and preservation of cultural heritage, the shoreline dynamics study, the wave movement for costal protection, soilerosion, etc. Clasic photogrammetry with the use of metric cameras are still of great use in areas such as architecture andenvironmental imaging. An old problem occurs when we want to extract metric information from our environment using clo...

Abstract The purpose of the research is to highlight the impact of two aspects defining personal identity: the HIV/AIDS status and family background, on the individual self esteem of young people having grown up in a family or an orphanage environment. We evaluated 93 young people from families and placement centers, both HIV-positive and HIV-negative, for a period of 12 months, from January to December 2013. We used the Self Esteem Inventory to evaluate their overall self esteem, as well as...

Abstract Diclofenac (DCF), which belongs to nonsteroidal anti-inflammatory drugs (NSAIDs), is a biorefractory micropollutant and its removal from wastewaters has become strongly necessary. This paper dealt with the DCF removal from aqueous solutions by electrooxidation at boron-doped diamond (BDD) electrode. In addition, the dual character of BDD electrode in electrochemical degradation processes and their control was investigated. The electrooxidation process was assessed based on ultraviol...

Abstract The application of Information and Communication Technologies (ICT) for water supply systems has steadily increased in the last 20 years. The city of Milan is presented as case study where the main challenge for the coming 20 years is the efficient use of energy. Opposite to other parts of the world, in Milan, water is neither scarce nor there is a growing need for supply. Given that the system completely relies on pumping, optimization algorithms and sensor technologies can be appl...

In past ten years area of green technologies and materials was the most growing industry sector in the world. It is related with global warming, air pollution and energy saving. Building sector intensively increased air pollution and is related with high energy consumptions. The use of renewable or recyclable materials can reduce these problems. In current work, thermal insulating materials from hemp shives and corn starch were investigated. Structures of various shives fractions were analyz...

In studies of biochemical methane production (BMP) researchers often collate a large number of samples at the same time for a sample archive. The samples are often frozen to avoid microbial transformation, further homogenized by grinding. We studied the influence of subfreezing/thawing and drying/milling of energy crop on BMP and anaerobic biodegradability (BD). Relative standard deviation (RSD, %) between the BMP of controls and of the subfrozen was in the range 2.1–9.0%, and of the d...

The objective of this work was to evaluate the effects of six lactic acid bacterial strains originated from different natural habitats of fermented food and feedstuff on pasture grass and alfalfa laboratory scale silages. The prepared mini silos were inoculated with the following bacterial strains alone or in combination: Lactobacillus brevis LbB (2x107 cfu/mL), Enterococcus faecalis EF (3.6x108 cfu/mL), Lactobacillus plantarum subsp. plantarum LbP (2.8x108 cfu/mL), Weissella paramesenteroide...

The paper offers information on the energy efficiency of the honey production in the mountainous area of Romania. The field research was carried out as a face-to-face interview in 2018, on a representative sample including 134 beekeepers. The main results of the analysis of the energy input–output are: input energy 754.9 MJ/hive, net energy -417.3 MJ/hive, efficient energy use 0.47 and specific energy 27.0 MJ/kg. From the total inputs, direct inputs and renewable inputs account for 38.1% a...
