Young Ecologist Talk and Interact (YETI) is a unique conference in many ways. It is one of the few conferences in the world and the only one in India which is organized by the students, for the students in the field of ecology and conservation. YETI has no fixed venue and it travels across the length and breadth of India, going where the team of students takes it. The onus of organizing YETI is totally up to a self-made team of student organizers, who come together and propose this to an ever-increasing group of YETI members.Full Text

The aim of this work is to evaluate the performance of a newly developed multi-walled carbon nanotube (MWCNT) reinforced alumina inserts. Machining of 'difficult to machine' materials requires harder cutting tool. So, for machining hardened materials, reinforced ceramic inserts with enhanced mechanical properties like fracture toughness and hardness are used. In this research work, multi-walled carbon nanotube reinforced alumina nanocomposite is used as a cutting tool that has Vicker's hardness value of 20GPa and fracture toughness of 6.43 MPa m1/2. Machining of AISI 4340 steel rod is done under dry environment. Progress of tool wear at two cutting conditions is evaluated. Tool life of the newly developed insert may be improved by employing suitable machining environment, proper tool geometry and parameters during production of the MWCNT reinforced alumina insert.Keywords

This paper concerns with machinability studies in finish turning of AISI 52100 steel using various tool inserts. This steel is applied in different structural and other industrial applications. Turning tests are performed under different cutting velocity and feed with plain, narrow groove and wide groove coated carbide tool inserts. Using these diverse conditions, types of chips formed, cutting force, etc., were noted, and machinability of the tool-work combine under different conditions is explored, so that some conditions can be found out at which good machinability can be achieved. Although narrow or wide groove chip breakers are used, chip breaking is not much observed in general. Fair machinability is observed while turning using all the three types of inserts. However, fairly good tool performance is obtained when plain carbide insert is employed at higher cutting velocities of 174 and 274 m/min at the chosen feed even in dry condition.Keywords

This paper concerns with machinability study by judging cutting force, chip formed and chip reduction coefficient while finish turning of AISI 52100 steel employing a number of tool inserts in wet environment. This kind of steel is utilized in constructing different structures, equipment, etc. Turning tests are carried out with varying speed-feed combinations. Narrow groove, plain (without any groove) and wide groove coated carbide inserts are used. Chip formed, cutting force components, etc. are observed. From the results obtained, some conditions are tried to explore corresponding to desired machinability. Good machining performance is reported with plain tool insert at the cutting velocity of 161 m/min and 253 m/min within the scope of the present work.Keywords

The Asiatic golden cat Catopuma temminckii also known as the Temminck’s cat is a medium-sized wild cat distributed throughout South Asia. Asian Golden Cat is currently listed as Near Threatened in the IUCN Red List, and also listed in the Appendix I by CITES and Scheduled I in the Wildlife (Protection) Act, 1972 as the current population has been found to be declining due to habitat loss and poaching. It is a shy and elusive mammal, and very little information is available on its range, habitat and behaviour. The present study was conducted during the month of February and March 2017 as part of the Biodiversity assessment in the Indian Himalayan landscape through long-term monitoring protocol under the National Mission on Himalayan Studies, funded by the Ministry of Environment, Forest and Climate Change, Govt. of India. During the fieldwork in Neora Valley National Park, camera traps were deployed to record presence of mammals and ground birds. An Asian Golden Cat (Catopuma temminckii Vigors and Horsfield, 1827) was photo-captured in a single camera trap deployed in a trail in Thosum Beat of the Neora Valley National Park. The camera trap photograph confirmed the Asiatic Golden cat, presence in the National Park, and therefore, a long-term study in its probable habitats in South Asia may reveal its distribution, population status and ecology which will help towards long-term conservation of this species.Keywords

The Marbled Cat (Pardofelis marmorata (Martin, 1837)) is an elusive and near threatened species as per the IUCN assessment and listed in the CITES Appendix – I. Present study record the first photographic evidence of Marbled Cat Pardofelis marmorata (Martin, 1837) in the Neora Valley National Park, Central Himalaya, India. Although, it was recorded from many parts of its range, the two camera trapped photographs within the National Park is claimed to be the first ever evidence of its occurrence in the Park. Nevertheless, many other ecological information such of population size, food and feeding behaviour etc. on the species is still unknown. Neora Valley National Park has not been given much of priority in terms of studying the ecology of the small carnivores existing inside the park and therefore need further investigations.Keywords

Employing conventional machining operations in material removal type manufacturing processes for processing difficult-to-machine hard materials through some ways and means is the focus of research by machining research groups across the globe since long. This gives considerable advantages over the grinding process in terms of higher material removal rate, better surface integrity of the work surface, etc., although grinding is commonly used for material removal of quite hard materials along with their finishing. In this paper, machinability of hard AISI 4340 steel is explored employing groove-type chip breaking coated carbide inserts under various cutting velocity and feed at dry condition. Hardened AISI 4340 is considered to be a difficult-to-machine material, and hence, recommendable machining conditions need to be found out. Favourable flat continuous chip is acquired at a cutting velocity of 231 m/min and at a feed of 0.08 mm/rev. At 391 m/min cutting velocity, cutting edges are detected to have worn-out quite fast.Keywords

An investigation on machinability study on hard grade AISI 4340 steel with carbide cutting tools during turning is reported in this paper. This steel is employed in military aircraft, automotive systems, forged hydraulic systems and other machine tools. TiC coated groove type SNMG 120408-PM and TiC coated plain SNMA 120408/315 K15 carbide inserts are used under dry condition at a constant depth of cut. Wear test is also done. Turning tests employing groove type insert give desired performance, eg. high material removal rate, low tool wear rate and broken chips at a feed above 0.1 mm/rev with no built-up edge formation.Keywords

Cutting fluids play a significant part of metal working industries. They are broadly utilized due to their capacity to diminish tool wearing, cutting force, temperature, etc. to improve workpiece surface quality. The present work focuses on the machinability study of hard AISI 4340 steel using eco-friendly cutting fluids. Turning experiments are carried out using coated carbide inserts through Small Quantity Lubrication (SQL) under different cutting velocities and feed. Dry, rice bran oil-based solution and alkaline solution are chosen to be the environmental conditions. Under different machining conditions, types of chips, cutting force, surface roughness, etc. are noted. Full factorial type response surface methodology is used to decide on experimental runs. Tool wear tests are also performed under wet conditions. Cutting force is observed to be significantly reduced in a chosen wet environment under some cutting conditions. Rice bran oil-based emulsifier is found to perform better than alkaline solution to increase tool life.Keywords
