Friction Characteristic of Bearing Alloy Steel used in Tractor

Paper ID- AMA-21-09-2022-11691

The purpose on this research is to examine friction characteristics of bearing alloy steel with paraffin oil lubrication and nitrogen gas lubrication in the cylinder block on tractor. Bearing steel is a type of steel with high resistance to wear, relatively low cost, and superior mechanical properties. An experiment was done to analyze the friction characteristics without using a coating treatment. The friction tests were performed using a pin-on-disk tester. Friction tests were conducted with different loads of 2 to 10 N and sliding velocities of 0.06 to 0.34 m/s using bearing steel. The experiment was done with nitrogen lubrication and paraffin oil lubrication. Paraffin oil lubricant was used to prevent wear during process. Nitrogen is shown to be effective for reducing the friction coefficient of bearing steel materials that are in contact with each other and subjected to a load and velocity.

Characteristics of Thermal Insulator for Various Aluminum-cotton Layer in Greenhouse

Paper ID- AMA-21-09-2022-11690

Greenhouse is known as one of the media commonly used for the planting process with a room control system. In accordance with its work objectives, a greenhouse was formed to be able to produce a room whose environmental conditions can be controlled properly. The use of aluminum-cotton as a greenhouse cover material is expected to be an alternative to better maintain temperatures in the greenhouse and also more economical. Lately the improvement of cotton features in various fields and utilization has also begun to be done. In this study, variations in fabrication layers were made to determine the effects of layers and also the appropriate type of fabric used as thermal insulators. There were nine types of aluminum cotton fabric layers as the variation. As a testing tool, the heating simulator system was self-designed using wood and aluminum plates. The analysis conducted in this study was the temperature changes that occur in the control room after 5 and 10 minutes of testing. The results of analysis showed that variations in fabrication layers provided a significant effect on material weight, controlled room temperature after 5 minutes, and controlled room temperature after 10 minutes. The most suitable samples to be used as thermal insulators based on tests in this study were samples A and E, which showed that there was a significant increase in temperature after 5 and 10 minutes of processing: 5ºC and 6ºC for sample A, and 1.67ºC and 2ºC for samples E.

ISOLATION AND IDENTIFICATION OF BRUCELLA MELITENSIS IN SHEEP IN TAMILNADU

Paper ID- AMA-21-09-2022-11689

The present study was carried out to find out the cause for abortion in a sheep flock in Thanjavur district of Tamilnadu, India. Out of 100 sheep in the flock, 20 abortions were recorded by the farmer. Based on the report, Vaginal swabs from recently aborted sheep and sera samples were collected from all affected animals. All tested sera samples were found positive for brucellosis. Culture and isolation were done on nutrient agar and blood agar media. Primary characterization was carried out by catalase test, oxidase test and modified ZN staining technique. Two suspected cultures were subjected to molecular characterization using the B.melitensis specific primers (IS711) found to be positive for Brucella melitensis. Outbreak of Brucellosis has been confirmed. This is a primary report of Brucella melitensis outbreak in Cauvery delta region of Thanjavur district, Tamilnadu. Study shows the occurrence of Brucella melitensis in the area which is of major zoonotic concern.

Digital Image Processing based Severity Indexing of Yellow Vein Mosaic Affected Okra Plants (Abelmoschus esculentus L.)

Paper ID- AMA-21-09-2022-11688

Monitoring of the plant health is an important aspect for mitigation of the infestation problem in agricultural farm. In this context, visual interpretation by human eyes of the infected plants was taken an account to diagnose the infestation symptom. However, quantification of the digital photographs taken by digital camera may be the substitute to quantify the infestation of the plants. Yellow network of vein is very conspicuous and difficult to calculate the disease severity in plant by visible interpretation, and to bridge this gap, computer vision or computer system-based quantification may be more accurate, precise and efficient way to diagnose the yellow vein mosaic in okra (Abelmoschus esculentus L.). Hence, the present study was carried out to develop an index using digital photographs of the infected okra plants which led to trace out the severity of the yellow vein mosaic virus. Results revealed that the lowest digital value (1-2/0.39-0.78 %) of the derived equation was least problematic compare to the digital value of 5-12 (1.96-13.33 %) in digital value of 0-255 in 8-bit size. Photographs in serial number 1,3,4,5 and 6 were observed as very low problematic symptom.

Entomopathogenic Nematode and Insect pest Management: A Review

Paper ID- AMA-21-09-2022-11687

The entomopathogenic nematodes of the genera Steinernema and Heterorhabditis have capacity to manage insect pests mutually and interact with bacteria of the genera Xenorhabdus and Photorhabdus. These nematodes kill insects within 24 to 28 hours by interacting with their symbiotic bacteria in contrary to other biological control agents that take days or weeks to do so. Entomopathogenic nematodes know to have great insect management potentially and also known safer to non targeted organism and effectively work with their symbiotic bacteria. The biological control agents like fungal bacteria and other micro-organisms require longer time for insect killing. The infective juveniles (IJs) are known to tolerate short-term exposure of various chemical compounds like insecticide, fungicides, herbicides, fertilizers including nematodes and growth regulators and provide opportunity of mass application. They are also known to be compatible with other biocontrol agents under various agro-climatic conditions. The use EPNs can also offer a cost-effective alternative to insect-pest control. Till today only about 12 species out of nearly 182 identified belonging to genera Steinernema and Heterorhabditis have been promoted to be used on commercial level. To help students and researcher understand their activity under field condition and to conduct in depth research on a variety of entomopathogenic nematode relative topics, this article summarises the work carried out in india & abroad integrated pest management systems. Although more research is needed, the use of EPNs can protect agriculture crops from the harm that insects do while having no adverse effects on people, animals, or the environment.
