Published: August 2019

Uberhood is an aerodynamically designed structure offering protection for the rider from sun and rain. In this paper, a preliminary attempt is made to design an uberhood for motorbikes followed by fluid flow analysis using Computational Fluid Dynamics (CFD).In this study, the k-ω turbulence model was employed to simulate a three dimensional flow past an uberhood. Comparison between flow past motorbike with rider and motorbike with uberhood along with rider are presented at two different angles of attack. The results in terms of the aerodynamic force coefficients namely the lift and drag coefficients, pressure contour, velocity contour, streamlines and turbulence kinetic energy obtained using the above turbulence model have been presented and discussed. Based on the height and velocity of motorbike with rider and motorbike with uberhood along with rider the Reynolds number was taken as 1.9 million and 2.2 million respectively. It was observed that with the increase in angle of attack the coefficient of drag decreases. Results show that a lower coefficient of drag value for the designed uberhood. This paves way for the use of uberhood in a motorbike which provides safety for the riders together with experiencing lower drag force.

Published: August 2019

Water alternating gas injection process (WAG) is a tertiary oil recovery technique commonly used to enhance the displacement efficiency of the residual oil which cannot be recovered during the primary and secondary recovery processes. In this study, experimental tests were conducted in a transparent water wet microporous model packed with glass beads and initially filled with crude oil. Alternate cycles of gas and water were injected to characterize the dynamics of three-phase flows and its associated oil recovery. The displacement of the residual oil at the end of each WAG injection cycles were studied in detail using the state of the art image processing techniques. It was observed that, the continuous cycles of WAG injection have helped the saturated residual oil to spread across the porous region and effectively displaced the residual oil that remained inside the water wet porous media after the initial water flooding. Obtained experimental results helps to understand the WAG process in detail and further it helps to validate future numerical models related to this process.

Authors: Bhargva Mohit , Yadav Avadhesh
Published: August 2019

Solar still play an important role in mitigating potable water scarcity mainly in developing countries because of its low-cost and easy design. One major concern regarding solar still is the low productivity. Using a wick in still basin decreases active water depth and increases the evaporation rate of basin water. In the present work, a comparative study of single slope solar still using different wick materials is performed. Bamboo cotton, jute, wool, and cotton are used as wick materials. To carry out experiments, two single slope solar stills of similar dimensions are designed and constructed. Wick is placed over the rectangular shaped fins installed in the still basin. The experiments are conducted for 25 days and data collected on the clearest sunshine days are presented in this work. Water depth is kept constant at 1 cm throughout the experiments. Experimental results showed that maximum still productivity and efficiency is obtained using bamboo cotton wick as 3.03 l/m2day and 34.5% respectively. This is 16.9%, 20.7%, 37.8% and 51.9% higher than jute, cotton and wool wick and conventional still. It is evident from the experimental results that bamboo cotton is the most suitable wick material in comparison to others.

Published: August 2019

Next generation modern aircraft gas turbine engines (GTE) should provide ultra-low emissions, higher operating efficiencies and cost-effective production and use of energy with decreased emissions at local and global levels. However, the combustors particularly developed for ultra-low NOX emission combustors being developed for aircraft gas turbine engines are more susceptible to combustion instabilities. Premixed combustion systems have the capability to meet future regulations on NOx emissions. However, premixed systems always involve the risk of flame flashback into the premixing section. From a gas turbine manufacturer’s point of view, it is required to enlarge the safe operating range, in particular with respect to flame flashback. The significance of these flashback phenomena is a strong function of fuel composition and operating conditions. In the literature, flashback along the wall boundary layer shows the most critical failure mechanism for many burner configurations using hydrogen-rich fuels. Therefore, in the past few years, Government, academia and several industries conducting extensive research in this area for the introduction of green technologies as lean fuel combustion and premixed burners in aero-engines. Therefore, this review paper focus on flashback propensity mechanisms in more detail and the conclusions are drawn as to mitigation technologies.

The parabolic dish concentrator is one of the most efficient technologies to convert direct beam radiation into thermal energy for steam and power generation. The parabolic dish concentrates direct beam radiation from the sun on to a receiver at the focal point. The receiver plays a major role to transform the reflected solar radiation into thermal energy. The conversion efficiency of the dish is severely influenced by imperfection of the dish collector such as the contour of parabola, size of the facets aligned, positioning of the receiver and tracking of the system. These imperfections are mainly involved in the design, manufacturing, construction and operation of a parabolic dish collector. To overcome this imperfection, secondary reflector are normally deployed at the focal region of the receiver. The function of the secondary reflector reradiates the deviated rays from the primary concentrator onto the receiver. In this aspect, flat receiver is initially fabricated to evaluate the performance of the flat receiver without secondary reflector. In this paper, the experimental investigations on flat receiver for 12.6 m2 area of solar parabolic dish concentrator system to estimate the receiver temperature and overall heat transfer coefficient of the flat receiver. In order to estimate this, rectangular box type aluminium receiver is fabricated and placed at the focal point of 2.42 m from the base of the dish. The aperture area of dish concentrator system is 12.6 m2 area and it consists of 12 petals and in each petals 128 flat mirrors of size 7.5 cm × 7.5 cm with reflectivity of 0.95 are pasted on 1.2 mm thickness MS plate to form a parabolic dish concentrator. The azimuth and elevation manual tracking arrangements are made to track the dish continuously for different orientation of the sun. K-type thermocouples are used to measure the temperatures of the top and bottom of the receiver. To measure the maximum temperature of the receiver, experiments are carried out for stagnation conditions (without heat retrieval from the receiver). Experiments are carried out on 5th, 6th and 7th March 2018 from 10.00 am to 3.00 pm. For different direct beam solar radiation, the top and bottom temperatures, ambient temperatures are measured. The maximum temperature of 399°C is achieved at the bottom surface of the flat receiver for the beam radiation of 955 W/m2, and the corresponding top surface temperature of 58°C is achieved for the same flux. Based on the measured bottom surfaces temperatures, the overall heat transfer coefficient of bottom surface are estimated as 145.56 W/m2 K. Based on this study, further heat transfer analysis will be carried out for the developed flat receiver.

Authors: Das S , Solomon S S , Saini A
Published: August 2019

This study presents thermal performance analysis of paraboloid dish type solar cooker under steady and unsteady state conditions. The performance is analyzed under two conditions: firstly steady state operation of cooker subjected to radiation and convection losses from vertical cylindrical surface & top cover of the cooker and secondly unsteady state operation of cooker associated with mass transfer from cooker to the surrounding when heat is supplied at a constant rate to the cooker after saturation pressure is reached.

Under steady state condition, predicted value of average thermal efficiency of cooker is 54%, first and second figures of merit are respectively 1.7 and 3.4, time taken to raise the temperature to 95°c is 24 minutes and time for boiling is 26 minutes. The difference in predicted and experimental results can be attributed to unaccounted losses from the cooker surface and operational error. In the second case, energy leaves the cooker with steam at a rate of 0.91 kW, accompanied by heat losses by convection and radiation from the outer surface of the cooker.

Published: August 2019

Non-petroleum-based fuels help in mitigating climate change by reducing the emission. Many studies on the emission characteristics for the alternate fuel dimethyl ether (DME), resulted in a significant reduction in NOx, SOx, and particulate matter. Due to the potential impact of the use of DME, a need for an Alternate fuel powered Micro gas turbine power plant for high altitude flight was investigated. The potential energy of DME reacting with oxygen was calculated in the temperature range 800-1350 K at the total pressure exhibited on combustion chamber similar to that of high altitude flight. Multichannel ab-initio and RRKM calculation were performed on the DME combustion reaction in the presence of air C2H6O+O2+N2→CO2+H2O+N2. The computed energy value obtained at low pressure was used to study the thermodynamic cycle of a 6kW micro gas turbine power plant for the use of power generation at high altitude flight system. The resulting energy flow model obtained is significant to understand the system performance and efficiency optimization.
Investigation of cyclic variations in air-fuel ratio, cylinder wall temperature, and residual gas fraction of a dual fuel compression ignition engine
Authors: Raj Saxena Mohit , Negi Suprim , Kumar Maurya Rakesh
Published: August 2019

Dual fuel operation in compression ignition engines is an effective way to reduce the NOx emission. Within the certain range of fuel premixing ratio (PR), the dual fuel operation in CI-engines results in improved thermal efficiency. The dual fuel CI-engine has relatively higher cyclic variations in comparison to conventional CI-engine which limits the range of fuel premixing in dual fuel CI-engine. The cyclic variations in air-fuel ratio, cylinder wall temperature, and residual gas fraction are the major factors, which governs the variations in combustion parameters. The cyclic variations in combustion need to control for stable engine operation. The present study estimates the cyclic air-fuel ratio, cylinder wall temperature, and residual gas fraction from the measured in-cylinder pressure data of dual-fuel CI-engine. The experiments are performed on a modified single cylinder CI-engine equipped with a separate port fuel injector and its controller to operate an engine in dual fuel mode. In this study, 1500 consecutive engine cycles are recorded, and air-fuel ratio, cylinder wall temperature, and the residual gas fraction is estimated for each cycle. Pressure moment method is used to estimate the cyclic air-fuel ratio. The cyclic cylinder wall temperature is calculated by determining the inversion angle. The cyclic variations are analyzed using statistical methods.

Published: August 2019

Renewable energies are sustainable and expected to play the significant role for pollution-free energy supply soon. Most traditional renewable energies are solar energy, wind energy, bioenergy, geothermal energy, tidal energy, and hydro-energy. Moreover, solar energy is characterized by their intermittent nature, as it is not available all the time. Another characteristic of these types of energy source is strong fluctuations (on the day), i.e., strong variations of available energy. This intermittent and fluctuation problem can be resolved by energy storage. This paper presents the performance studies on a forced convection solar air heater integrated with the latent-heat type thermal energy storage. The thermal energy storage is designed to maintain 50°C to 55°C temperature during sunshine hours and off sunshine hours especially for food processing. The experimental studies were carried out in the month of summer 2018. The average percentage of the energy recovered is found to be 44 % during the trials. There is a 6°C to 9°C temperature difference between thermal energy storage outlet and ambient air was invariably observed for 6 hours after adequate sunshine hours which is noticeable. Further, the maximum temperature of flat plate type air heater was not increased beyond 70 °C while the maximum outlet temperature from thermal energy storage system was observed 56°C during the entire day during the experiments. It shows no overheating of the system and assures outlet air in the required temperature range for food processing. This system is most useful with the solar dryer which can be used to dry fruits, vegetables, and fishes. This system can also be customized for any particular food item too.

Authors: Lesovskaya M I , Shaporova Z E
Published: August 2019

Using molecular enhancers of chemiluminescence, the regulatory effects of several essential oils on the production of primary and secondary biogenic free radicals in vitro were investigated. For the more correct extrapolation of the results, the human blood phagocytes as biogenic source of free radicals was used in an experimental model during latex stimulation and without it. The antioxidant activity of pine essential oil against primary and secondary biogenic radicals was identified, and the prooxidant activity of eucalyptus essential oil against primary and secondary biogenic radicals was determined. Unlike both of these substrates, the modulating effect of lavender essential oil was identified. Under the influence of this substance luminol-dependent chemiluminescence increased, while lucigenin-dependent chemiluminescence decreased without changing the basal activity of phagocytes. Essential oils of lemon and peppermint acted as radical-specific antioxidants. Under the influence of peppermint essential oil, the production of primary not secondary radicals decreased significantly. Under the influence of lemon essential oil, the production of secondary radicals decreased while production of superoxide did not change significantly. Based on the results are obtained, it is possible to develop or adjust the schemes of health-improving and preventive procedures, as well as to optimize the choice of adaptogens chemical forms.

Kabardino-Balkaria, occupying a little more than 0.07 % of the total area of Russia, produces almost 1.0 % of agricultural products, including 0.85 % of grain (more than 1.1 million tons and more than 1300 kg per person, whereas in the country this figure is only 920 kg), for vegetables it is more than 3.6% (about half a million tons and more than 576 kg per person, whereas in general in Russia it is only about 93 kg), for fruit and berries it accounts more than 8% (producing more than 215 thousand tons and almost 250 kg per person, despite the fact that in the country it is just over 18 kg). All this is achieved not due to the size of the sown area, which accounts for 0.35% in the sown area of Russia, but due to the introduction of new technologies, among which artificial intelligence (AI) plays an important role, ensuring the growth of labour productivity, yield and food production. The industry is in the process of separating the sub-sectors (and segments) associated with the use of AI and the formation of a corresponding subsystem, which in the future may be separated into an independent industry. In this regard, a number of problems arise, first of all, overcoming the transfer of AI created in agriculture, secondly, the transition from the so-called point or localized use of AI to the system, through the expansion and deepening of the use of AI. Apparently, in both cases we are talking about the transition to a new, more perfect form of AI. The above-mentioned issues are described in the paper.

Development and creation of software systems for managing groupings of unmanned aerial vehicles today is a promising and rapidly developing area of the modern software industry of high-tech aerospace instrumentation. To date, a single well-established and scientifically-based understanding of the canonical architectonics of such software systems has not been developed. The paper shows that in software systems for managing unmanned aerial vehicle groupings, as in real-time software and information systems, a different information processing organization scheme is required, different in the implemented sequence of analysis procedures for input but unsystematic digital data. A conglomerate of knowledge-intensive software technologies for processing data and knowledge, integrated into specific implementations of software systems for managing unmanned aircraft groupings, is unstable and difficult to combine, which is the main threat to ensuring the high quality of such software systems.
Adaptogenic effects of essential oils: prognosis in vitro and results in vivo
Authors: Lesovskaya M I , Shaporova Z E
Published: August 2019

The results of a two-week in vivo experiment confirmed the adequacy of the in vitro prognosis about the possibility of oxidative balance correction. The prooxidant effects of cedar, orange and lavender essential oils (by inhalations) on the free radical production by blood phagocytes were investigated using a chemiluminescent (CL) test. The results obtained in vivo are in good agreement with those obtained in vitro models. Consequently, with the help of express CL analysis, it is possible to prognose the direction and intensity of changes in the free radical balance of the internal environment of the body under the influence of essential oils. Two conditions are necessary for such a forecast. The first, preliminary definition of the functional status of the blood phagocytes using express CL-analysis is required for an individual person. Secondly, information is required about the antioxidant or prooxidant potential of essential oils, which the person has chosen when he oriented on organoleptic parameters or objective recommendations. Individual selection of essential oils as biologically active metabolic regulators will avoid the risk of unwanted side effects in aromatherapy. Using this approach, manufacturers and distributors and consumers receive a preliminary assessment of the antioxidant and prooxidant activity of essential oils.

GM analogues have about 30 plant species, and main share from GM crops belong to soybean and corn. According to the literature data, the introduction of GM fodder in the diet of laboratory mice and rats was accompanied by negative consequences for the health of experimental animals and their offspring. Corn is a component of animal feed and popular product among people, especially sweet canned corn. The lack of experimental data regarding effects of canned sweet GM corn on an organism was the drive behind our research subject. The objective of the research was a comparative analysis of hematological and biochemical parameters of laboratory mice with a conserved GM corn based diet and without it. Clinical blood analysis indicated the development of hyperchromic anemia, leukocytosis due to an increase in the fraction of medium blood cells and thrombocytosis in experimental group mice. Biochemical studies of these mice blood revealed signs of renal and liver pathology, myocardial damage and hyperproteinemia. A comparative analysis of the hemato-biochemical status of laboratory mice indicated the development of signs of anemia, intoxication and allergy in the group of mice with a conserved GM corn based diet as compared to intact mice of the control groups.

Rice is the staple food of many nations of the world, as it gives the greatest amount of grain per unit area. The most important task in developing a new high-yielding variety is to increase the technological indicators of grain and milled rice quality, or at least to keep them at the optimal level (standard-check variety). Rice for food purposes is used in the form of cereals, as an admixture to bread or confectionery, in the production of flakes, puffy grains. This is due to the demand for high-quality rice with excellent taste and culinary qualities in a dynamic market.

This article presents the results of three-year studies on the formation of technological indicators of grain and milled rice quality with different heat supply during the growing season. It is established that the accumulation of heat in 2016-2018. exceeded the average long-term data (783 °C) - 1054, 1089 and 1238 °C, respectively. Under these conditions, the varieties VNIIR 10244, VNIIR 10276 and VNIIR 10279 with a mass of 1000 grains - 29.3; 30.5 and 30.4 g, respectively were selected, significantly exceeding the standard (27.8 g). Vitreousness in all varieties was at a high level - 89.7-97.7%. Filming over the years of research varied on average from 17.7 to 21.4%. The fracture of the presented varieties was 4.7-32.3%. The varieties VNIIR 10275, VNIIR 10278 and VNIIR 10828 showed the maximum resistance to grain cracking - 9.7; 9.3 and 4.7%. Total milling yield in almost all genotypes was at the level of variety Flagman (st), with the exception of VNIIR 10278 (72.7%), which significantly exceeded the standard. By head rice content the variety VNIIR 10282 turned out to be significantly higher than the standard, and the rest within the LSD05. The correlation of technological indicators of grain and milled rice quality with the heat supply of the growing season were revealed. It was established that the varieties VNIIR 10279 and VNIIR 10282 by head rice content weakly correlate with heat supply. There are also varieties (VNIIR 10275, VNIIR 10276, VNIIR 10277 and VNIIR 10282) with a weak connection of a mass of 1000 grains and the sum of effective temperatures (0.60; 0.18; 0.27 and 0.36, respectively). This fact suggests a weak variability of these traits in new rice varieties with heat accumulation, which determines their genetic nature and the possibility of forming a high-quality yield.

The target of the survey is to study the efficacy of Enrofloxacin 5% and its lower doses used for the therapy of bovine anaplasmosis and efficacy of Enrofloxacin 2, 5 and 5% used for treatment of canine babesiosis. Enrofloxacin 5% has a pronounced therapeutic effect in treatment of anaplasmosis in cattle used at a dose of 1cm3 per 20 and 30 kg of body weight while using the preparation at a dose of 1cm3 per 40 and 50 kg of body weight the therapeutic effect was practically not observed. At the same time Enrofloxacin has no therapeutic efficacy against canine babesiosis.

The influence of glyphosate on the germination and development of bread wheat (Triticum aestivum) was researched. The chronical influence during all the time of growth was estimated, together with the consequences of the contact with glyphosate of the already formed seedlings. A dose-dependent decrease in the growth rate of seedlings in the presence of glyphosate was found, and even in normally developing seedlings damage to the root tips was observed. In particular, in seedlings, the integrity of the root cap was disrupted, degenerative changes of the rhizodermis and root hairs were detected. It has been shown that a decrease in the root growth rate during chronic exposure is largely due to the suppression of mitoses. In addition, high glyphosate concentrations had a general toxic effect, stopping the development of seedlings yet at the stage of primary roots growth through enlarging the cells. It was found that the antioxidant system of seedlings prevented the development of oxidative stress at the concentration of herbicide 50 μM, in particular, due to the activation of peroxidase. Placing seedlings grown on distilled water in 100 μM glyphosate solution induced lipid peroxidation. Chronic effects of herbicide in this concentration inhibited lipid metabolism in general.
The use of bovine multipotent mesenchymal stem cells isolated from bone marrow and adipose tissue as sources to obtain muscle cells in vitro
Authors: Korovina D G
Published: August 2019

The creation of muscle tissue with use of cell engineering technologies is currently being evaluated as one of the most promising areas in various fields of science. The aim of the work was to assess the in vitro potential of bovine multipotent mesenchymal stem cells (MMSCs) derived from bone marrow (BM) and adipose tissue (AT) to directed differentiation into muscle cells under the influence of various inducers. It was found that AT-MMSCs could differentiate into skeletal muscle cells (Sk-MCs) in response to inductive stimuli much more so than BM-MMSCs. When cultured for 28 days in the medium, supplemented with all-trans retinoic acid, bovine AT-MMSCs formed multinucleated myotubes and expressed markers of myogenesis MyoD1 and MyoG. The induction medium, including growth medium for myoblasts and horse serum, caused, in addition to myogenic differentiation, the appearance of adipocytes with lipid vesicles. The presence in the medium for differentiation of conditioned medium obtained from L6J1 rat myoblasts stimulated the directed differentiation of bovine AT-MMSCs into muscle cells, and the efficiency of its inducing action was higher. Thus, a sufficiently high potential of myogenic differentiation of bovine MMSCs has been demonstrated, these cells can be a potential source for large-scale production of Sk-MCs.
