The social nature of urban farming is a major motivation for growing food in a city as individuals and organisations work towards increasing access to healthy foods and also in connecting consumers and growers. It comprises variety of livelihood systems at the household level to more commercialised level. Furthermore, urban farming involves different discipline and approaches acquiring interest and attention in the field of architectural research. The main focus of this paper is on various aspects of growing crops in urban spaces. Urban Farming involves different types of food producing Spaces, Stakeholders, Resources and Policies that contributes health, social, ecological, and economic benefits to communities. Considering this huge potential, the paper intends to provide the necessary background on the trends seen in urban agriculture in built environment in New Delhi City initiated by individuals and community groups who have started urban farms as businesses and as non-profit social enterprises. This study also highlights its contribution in achieving Sustainable Development Goals(SDGs) that promotes food security.

An effective and efficient road transport system requires regular road maintenance. Road transportation facilitates the movement of people, goods and services in all sectors of the economy, including tourism, mining, trade, health, education and agriculture, among others.A growing concern for public transit is its inability to shift passenger�s mode from private to public transport. In order to overcome this problem, a more developed feeder bus network and matched schedules will play important roles. The present research aims to review some of the studies performed on Feeder Bus Network Design and Scheduling Problem (FNDSP) based on three distinctive parts of the FNDSP setup, namely, problem description, problem characteristics, and solution approaches. The problems consist of different Sub problems including data preparation, feeder bus network design, route generation, and feeder bus scheduling. Subsequently, descriptive analysis and classification of previous works are presented to highlight the main characteristics and solution methods. Finally, some of the issues and trends for future research are identified. This research is targeted at dealing with the FNDSP to exhibit strategic and tactical goals and also contributes to the unification of the field which might be a useful complement to the few existing reviews.

This paper intends to compare the performance parameters of a vortex tube setup having spinners made of two materials � Aluminum and PLA. The PLA spinner has been 3D printed using Prusa i3setup. The dimensions and design has been made keeping in mind that our setup is a counter flow vortex tube. The energy efficiency ratio was arrived at and compared.

Rankque Hitsh Vortex tube takes in compressed gas and produces cold gas. The major reasons attributed to this drop in temperature are sudden expansion, centrifugal effect, secondary circulation, friction. We have fabricated a vortex tube which uses air as working fluid and produces cooling effect. The flow characteristics such as temperature, pressure, discharge, mass flow rate, velocity etc. were measured. Our observations were tabulated and plotted. The values were obtained for input pressure such as 7-6bar, 6-5bar, 5-4 bar and 3-4bar. The vortex tube is used as cooling equipment in CNC machines, spot cooling applications etc. Since no moving parts are involved, this system requires less maintenance. Overall this paper intends to focus broadly on two aspects-geometrical characteristics of the vortex tube and thermophysical parameters involved.
