Authors: Dekhtyar R A , Ovchinnikov V V
Published: November 2019

An experimental study of hydrodynamics and heat transfer under conditions of filtering of water and aqueous solution of glycerol through a porous insert in the channel was carried out. The values of the coefficient of hydraulic resistance and heat transfer for a chaotic backfill of balls with a diameter of 3.2 mm for filtering water and 47% glycerol solution have been determined. Three flow regimes were investigated: inertial, transient and turbulent. It has been found that, depending on the filtering mode through the porous insert, there are various laws of heat transfer. Comparison of the obtained results on heat transfer in ball fillings with the available literature data has been carried out. The obtained experimental data are in good agreement with the data of numerical calculations. For the thermal stabilization section at high values of the Reynolds number they are in good agreement with the data obtained by filtering air through a porous medium.

Published: November 2019

Currently used recycling technologies have limitations on the composition of recyclable waste, which makes them specialized. Thus, the preliminary sorting of municipal solid waste is a necessary step, increasing the efficiency of using municipal solid waste as a resource. To sort municipal solid waste we developed a method for detecting and classifying waste on a conveyor line using neural network image processing. Images from a camera are fed to a neural network input, which determines the position and type of detected objects. To train the neural network a database of more than 13,000 municipal solid waste images was created. Mean-Average Precision for the neural network model was 64%.

Published: November 2019

Climate shocks are predicted to increase in magnitude and frequency as the climate changes, notably impacting poor and vulnerable communities across the Tropics. The urgency to better understand and improve communities’ resilience is reflected in international agreements such as the Paris Agreement and the multiplication of adaptation research and action programs. In turn, the need for collecting and communicating evidence on the climate resilience of communities has increasingly drawn questions concerning how to assess resilience. While empirical case studies are often used to delve into the context-specific nature of resilience, synthesizing results is essential to produce generalizable findings at the scale at which policies are designed. Yet datasets, methods and modalities that enable cross-case analyses that draw from individual local studies are still rare in climate resilience literature. We use empirical case studies on the impacts of El Niño on smallholder households from five countries to test the application of quantitative data aggregation for policy recommendation. We standardized data into an aggregated dataset to explore how key demographic factors affected the impact of climate shocks, modeled as crop loss. We find that while cross-study results partially align with the findings from the individual projects and with theory, several challenges associated with quantitative aggregation remain when examining complex, contextual and multi-dimensional concepts such as resilience. We conclude that future exercises synthesizing cross-site empirical evidence in climate resilience could accelerate research to policy impact by using mixed methods, focusing on specific landscapes or regional scales, and facilitating research through the use of shared frameworks and learning exercises.

Microplastics are a major environmental challenge, being ubiquitous and persistent as to represent a new component in all marine environments. As any biogenic particle, microplastics provide surfaces for microbial growth and biofilm production, which largely consists of carbohydrates and proteins. Biofilms influence microbial activity and modify particle buoyancy, and therefore control the fate of microplastics at sea. In a simulated ‘plastic ocean’, three mesocosms containing oligotrophic seawater were amended with polystyrene microbeads and compared to three control mesocosms. The evolution of organic matter, microbial communities and nutrient concentrations was monitored over 12 days. The results indicated that microplastics increased the production of organic carbon and its aggregation into gel particulates. The observed increase of gel-like organics has implications on the marine biological pump as well as the transport of microplastics in the ocean.

Published: November 2019

The main purpose of this research is to investigate the Tribological characteristics of Calophyllum Ester based Bio lubricant – commercial engine oil blends. The Bio lubricants used in this study are esters derived from Calophyllum seeds. The fatty acid content reveals the presence of saturates which form feed stock to esters. The physicochemical properties evaluated as per ASTM standards are found to be in an acceptable range. TMP (Trimethylolpropane) ester is blended with HP-RACER4 (Engine oil) in 5%, 10%, 15%, and 20% volume percentages respectively and tested for Anti-wear and Anti-Frictional properties using a four-ball tribo-tester. It was found that, although both the esters offer a very low coefficient of friction, the main drawback is their failure at higher loads. The blending of commercial lubricant with bio-lubricant resulted in lower friction and wear characteristics of the commercial lubricant. The optimum percentage of bio-lubricant in the commercial lubricant is found to be 20% which gave the desired results.
