Unmanned Aerial Vehicle Design for Smart City Application
Nowadays, Unmanned Aerial Vehicles (UAVs) or drones are also one of the applications to provide the required services and to gather information from the target location. Because smart city applications effectively deal the drone interaction and enhance the human lifestyle with drones. Moreover, UAVs are generally utilized due to their privacy threats, lower cost, pose security, and versatility, which request dependable detection at lower altitudes. However, the less sensing module in the drone has earned the low sensing accuracy of location tracking. So, this paper aims to develop a novel Firefly-based Recurrent Neural Mechanism (FRNM) to enrich the sensing capacity of the drone vehicle. In addition, the sound of the research is medicine delivery through UAVs in emergencies. This UAV system is one of the most crucial features to delivering essential medical items aids by reaching properly correspondent patients. Moreover, the client's needs are stored in the FRNM cloud then that stored data is trained to the UAV machine. Hereafter, based on the trained details, the drone can reach the destination and has delivered the requested medicine to the specific clients. The planned design is drawn in Network Simulator (NS2) environment, and the robustness of the projected replica is valued by calculating the chief parameters. Hereafter, the improvement score was valued by the comparison assessment. Hence, the FRNM has reported the finest performance by earning less location finding duration, running period, and error rate
Influence of pre-harvest application of gibberellin and brassinosteroid on fruit growth and quality characteristics of pear (Pyrus pyrifolia (Burm.) Nakai) cv. Gola
Quality of fruit crop is an important parameter to decide the acceptability of the product. The present study consists of seventeen year old pear (Pyrus pyrifolia (Burm.) Nakai) trees subjected to seven treatments viz., GA3 (50 ppm,100 ppm), BR (0.5 ppm, 1.0 ppm), and GA3 + BR (50 ppm + 0.5 ppm and 100 ppm + 1 ppm) and water as control, sprayed thrice at 15 days intervals starting from petal fall stage. Each treatment was replicated thrice with one tree served as a treatment unit. The experiment was conducted in Randomized Block Design. The fruits treated with GA3 @ 50 ppm (T1) showed the highest fruit length (6.98 cm), breadth (6.81 cm), weight (175.9 g) and volume (171.16 cc). An improvement in terms of fruit quality was observed either alone or in combined application of GA3 and BR. The application of BR @ 1 ppm (T4) recorded the highest TSS (12.91°Brix) and lowest titrable acidity (0.42%) while the highest ascorbic acid content (6.95 mg / 100 g) and non reducing sugar (0.44%) was estimated under GA3 @ 100 ppm + BR @ 1 ppm (T6). Total sugar (7.88%) and reducing sugar (7.45%) was observed highest in GA3 @ 50 ppm + BR @ 0.5 ppm (T5). Based on this research combined application of GA3 + BR had a positive effect and therefore can be recommended for spray on pear in order to obtain higher yield and better quality
The role of computed tomography in the evaluation of cerebrovascular accidents
Background:Cerebrovascular accidents (CVA) or stroke ranks first in frequency and important among all the neurological diseases of adult life. 50% of neurological disorders in a hospital are of this type. It is the third leading cause of death throughout the world. The prolonged morbidity and extended hospitalization required by these patients makes the disease one of the most devastating in medicine. The purpose of the present study was to document the presence or absence of hemorrhage or infarct, to determine the size, location of infarct, reasonably assessing the territory to blood vessels involved and to detect the incidence of negative cases of clinically suspected stroke.Methods:100 cases admitted to KIMS, Hubli and those referred to the NMR scan centre, Hubli with the clinical diagnosis of acute stroke were taken up for the study. The study was done from May 2010 to April 2012.Results:Out of 100 patients clinically suspected of CVA, submitted for CT scan study of the brain, 69 patients had infarcts, 21 patients had hemorrhage, 8 patients had CVT, 1 patient had SAH and 1 patient had normal scans. Infarcts (69%) formed the major group of the CVA cases involving most commonly the LMCA territory in 10 (14.49%) patients. Hemorrhage (21%) formed the second major group of CVA cases involving most commonly the RMCA territory 9 (42.85%) patients.Conclusions:CT scanning is a gold standard technique for the diagnosis and management of stroke and can be ideally done in all cases.The role of computed tomography in the evaluation of cerebrovascular accident
Electrochemical Pretreatment of Distillery Wastewater Using Aluminum Electrode
Electrochemical (EC) oxidation of distillery wastewater with low (BOD5/COD) ratio was investigated using aluminum plates as electrodes. The effects of operating parameters such as pH, electrolysis duration, and current density on COD removal were studied. At a current density of 0.03 A cm-2 and at pH 3, the COD removal was found to be 72.3%. The BOD5/COD ratio increased from 0.15 to 0.68 for an optimum of 120-min electrolysis duration indicating improvement of biodegradability of wastewater. The maximum anodic efficiency observed was 21.58 kg COD h-1 A-1 m-2, and the minimum energy consumption observed was 0.084 kWh kg-1 COD. The kinetic study results revealed that reaction rate (k) decreased from 0.011 to 0.0063 min-1 with increase in pH from 3 to 9 while the k value increased from 0.0035 to 0.0102 min-1 with increase in current density from 0.01 to 0.03 A cm-2. This study showed that the COD reduction is more influenced by the current density. The linear and the nonlinear regression models reveal that the COD reduction is influenced by the applied current density

Life cycle assessment of biodiesel production from pongamia oil in rural Karnataka
Pongamia pinnata is one of the promising tree species suitable for providing oil for biodiesel production. This paper addresses the life cycle energy balance, global warming potential and acidification potential, of a small scale biodiesel system, in rural Karnataka. In addition, the system has also been expanded to generation and use of biogas from seed cake for electricity production and evaluated for its environmental impacts. The environmental impacts have been benchmarked with the life cycle impacts of fossil diesel. The results show that non-renewable energy requirement of Pongamia biodiesel system is twenty-eight times lower than that of fossil diesel. A significant increase in global warming potential (GWP) is indicated in Pongamia biodiesel system compared to fossil diesel if wood is used as fuel. GWP would be seven times less if wood is not used as fuel. Acidification and eutrophication potential of Pongamia system was found to be nil. Further, expanding the Pongamia biodiesel system to include biogas production exploits the energy available in the system. It is also observed that one hectare of Pongamia plantation is capable of completely sequestering the CO2 released during the life cycle with additional sequestration potential up to 1 t CO2 ha-1. Moreover, the above aspects were significantly superior in Pongamia system when compared to Jatropha biodiesel system. Keywords: Biodiesel, global warming potential, acidification and eutrophication potential
Conservation of wild silkworm genetic resources through cryopreservation: Standardization of sperm processing
Conservation of the invaluable sericigenous genetic resources is of prime importance with respect to their utilization and improvement for wider exploitation. Conservation of wild silkworms and its applicability in hybridization have limitations due to incompatibility, less amenability, change of behaviour under ex situ conditions, non-synchronization of moth eclosion and difficulties in mating between variables. In view of this, the newer technologies such as cryopreservation and artificial insemination are offering better strategies for preservation of biologically active samples like semen at sub-zero temperature (-196º C) conditions for longer duration. In this context, under standardization of sperms preservation from wild silkworms, two methods of semen collection were scrutinized for obtaining active and viable sperm for cryopreservation and further artificial insemination. Semen collection from the seminal vesicle of freshly emerged male moth and the other from the bursa copulatrix (BC) and spermatheca of the female moth after mating. The sperms in the semen collected from seminal vesicle are in the form of bundles known as eupyrene sperm bundles and apyrene sperms. The morphology and behaviour of these sperm bundles were recorded through microscopic examination. To study the density and motility behaviour of the sperms, sperm bundles were treated with proteolytic enzyme (~2-3µg/ml) to digest the membrane and release the sperms. The density and motility behaviour of sperms in the semen recovered from the BC and spermatheca of female moth after mating were higher compared to those released after digestion of sperm bundles from seminal vesicle of the male moth
