 Abstract

The present investigation entitled �Effect of plant growth regulators on chemical composition of mango (Mangifera indica L.) cv. Dashehari.� was carried out at the instructional Farm, Deptt. of Horticulture, College of Agriculture, IGKV, Raipur (C.G.) during the year 2017-18 employing Randomized Block Design with three replications. Three levels of NAA i.e., 15, 25 and 35 ppm, three levels of GA3 i.e. 15, 25 and 35 ppm and three levels of 2, 4-D i.e. 15, 25 and 35 ppm were sprayed at pea and marble stage of fruit development. All the treatments significantly influenced the number of fruits retained at pea, marble and harvesting stage of fruit growth and development as compared to the control. Qualitative characters like TSS (21.61%) and ascorbic acid (57.63 mg/100g) increased with the foliar application of 35 ppm 2,4-D and 35 ppm NAA respectively. While, reducing sugar( 5.71%) , non-reducing sugar (14.26 %) and total sugar (19.97 %) were increased with 35 ppm foliar application of 2,4-D. Acidity content of fruit (0.17 %) was recorded minimum under the superiority of treatment foliar application of 2,4- D at 35 ppm concentration. Among the different concentrations of plant growth regulators; the foliar application of 35 ppm 2, 4-D were found to be optimum concentration by which chemical composition of fruits can be significantly influenced.

 Abstract

Conventional 2-level PWM inverters generate high dv/dt and high frequency common mode voltages which is very harmful in electric drives applications. It may damage motor bearings, conducted electromagnetic interferences, and malfunctioning of electronic equipments. Due to capacitor voltage unbalancing, neutral point potential also varies from zero. This paper presents a simple method to control the harmonics, common mode voltages and neutral point potential variation in neutral point clamped (NPC) inverters using different structures of sine-triangle comparison method such as Phase Disposition (PD), Phase Opposition Disposition (POD), and Common Mode Voltage off-set voltage addition method. Simulation results confirm the effectiveness of these simple methods to control common mode voltages. Neutral point potential variation is limited to less than 2% of dc capacitor voltage using a simple closed loop PI regulator.

 Abstract

In our daily life, time and traffic is an obstacle for our daily activities like business, travelling or transportation and for each of the work to be done takes a lot of efforts for a person, and even pollution will be happened while we are travelling and all. In this paper, a person (Traveller/Rider) can earn while travelling. Traveller will carry the products from his starting point or on his way which is capable for him and deliver it within his destination. It reduces traffic, pollution, expenses and saves time that will be taken for a buyer to travel twice will be reduced to half and even that travelling will be carried by another person for him, and here all the buyer have to do is to pay the price to the traveller for carrying the product and saving the buyers time. Project implementation is in the form of mobile application with java language, XML, PHP, SQL, Firebase and using android studio software, it includes location details of product to be delivered (initial and end point) and the location details of the person(initial and end point), and that is how the interconnection between product and traveller inter-relate in our project that the traveller can choose the product within his destination only if the product is within his destination This app provides a way for the carrier to earn free income without any big risk, all that he have to do is to just carry the product within his destination.

 Abstract

Insects represent the culmination of evolutionary development of terrestrial arthropods and have adopted to the most diverse types of environment. The transition from aquatic to terrestrial mode of life was a crucial step in the evolution of higher metazoa and undenieable so in the tracheaete arthropoda. Insects of any water body plays significant role in maintaining ecological balance and becomes part of food chain, food web at specific trophic levels .Besides , they functions as biological indicators for determining the water quality and pollution in respective water bodies. The present investigation also reveals the role of insects and their types in a particular water body i.e river Tawi in Jammu. In Jammu region there are so many water bodies starting from wells, ponds, springs, lakes, and reaches upto streams but lacking coastal areas or oceans since the region is surrounding by hilly terrain. The river tawi is considered as holly and sacred river from religious point of view and supposed to be a life line of the Jammu city and other towns located on the banks of river . During this investigation it has been observed that there are large no of insect species present in the river but maximum emphasis were given on the subject about presence of some developmental stages of insects found frequently on the river banks. The most common method used for this study was hand nets , scoops and forceps capturing and even manual capturing was also carried out keeping in view the harmless nature of insects .In this study about 2-3 kms area of river tawi were investigated near the main tawi bridge.It has also been observed and realized during the investigation that the impact of pollution gradually reduces the population of some important insect species in the river. There are about 4-5 species of insects were observed and studied at different developmental stages ( larval , nymphal and adults ).

 Abstract

In the present investigation barnyard millet seeds were mutagenized with different doses of gamma rays (GR) ranging from 100, 200 and 300Gy, varying concentration of ethyl methane sulphonate (EMS) 0.1, 0.2 and 0.3% and Sodium azide (SA) 0.01, 0.02 and 0.03%. Variations in the germination of seeds, seedling height, seedling injury and survival of plant at maturity of barnyard millet were recorded in M1 generation. The effects of the mutagenic treatments on quantitative traits resulting in reduction in traits such as seed germination except 100Gy (91.02%), 0.1% EMS (90.87%) seedling height except 100Gy (7.02cm) and 0.01%SA (7.18cm) and survival of plant at maturity except 100Gy (88.09%) and 0.1%EMS (87.57%) but increases seedling injury except 100Gy (-00.86%) and 0.01%SA (-3.16%) was observed in treated M1 generated plants.

 Abstract

Corona virus disease 2019 is phrase as COVID-19 is pandemic disease caused by severe acute respiratory syndrome corona virus 2 or SARS-CoV-2 it can spread from mild to sufficient to cause of death. The disease was first papulared in december 2019 in Wuhan, the capital of China's Hubei province. The COVID-19 disease which unfurl from infected person to healthy one by droplet, hand shaking, coughing, sneezing, so it is risk of having COVID-19 through mucosa( Mouth and Nose) or through the conjunctiva and even it transmits through indirect contact with surfaces in the immediate environment or with objectives used on the infected person. People may be risk with COVID-19 for 1-14 days before developing symptoms which termed as subclinical infections or silent disease, like cough, fever, tiredness, difficulty in breathing. It can be tested through cultures of nose and throat and there is no specific treatment for corona virus disease, only a symptomatic treatment is available to functioning of vital organ of the body. Recently researchers coined that convalescent plasma which boost their ability to fight against the corona virus. It can be prevented by maintaining personal hygiene, social distance between people, animal and in the hospital by maintaining sterilization techniques for the covid-19 objects and fallowing protocols of corona virus disease.

 Abstract

: The idea of using waste plastics in road construction is relatively new. Laboratory tests have shown positive results when a small amount (10-15% by weight) of plastic is incorporated in bituminous mixes (asphalt), resulting in improved pavement stability, strength, and durability. However, international field experience using plastics in actual road construction is quite limited. While roads constructed using waste plastics have shown good longevity and pavement performance to date, the first roads constructed using this technology are only about ten years old, so long-term outcomes are not yet clear. The mix polymer coated aggregate and modified bitumen have shown higher strength. Use of this mix for road construction helps to use plastics waste. Once the plastic waste is separated from municipal solid waste, the organic matter can be converted into manure and used. Our paper will discuss in detail the process and its successful applications
