It lies at 23 º 1' North and 72 º 37' East on the banks of the Sabarmati River. The city is in the region of North Gujarat, which is a plain, dry and sandy area, having maximum and minimum temperatures in the range between 44.3 º to 46.6 º and 4.8 º to 8.4 º C. The altitude of the city shows only marginal variations (46.6m to 50.9m). Except for the small hills of Thaltej-Jodhpur Tekra, the entire surroundings of the city are flat. The population of the Ahmedabad Urban Area (UA) in 2001 was recorded as 4.5 million. Increasing industrialization and economic development has resulted in the steep rise in the population and consequently has also resulted into the degradation of environment. City is left with limited natural resources like open spaces, water bodies, and places for social gathering. Here, urban water bodies plays multifunctional role. Large number of Natural Water Bodies (NWBs), which were once the inherent part of the city life, lost in the wake of development. The unauthorized and unchecked water withdrawal has led to the severe problems of its fast depleting ground water resource. Situation of NWBs in the city, in the recent past, has been very grim, with ever-decreasing number of water bodies/ talavs (ponds). In 1865 there were 218 NWBs, which fell to 132 in 1975 and further down to 62 in 2001.

In today’s world, the supply chain is a multi-faceted ecosystem linking product development, manufacturing and distribution networks into one fully transparent and digitized system. With multiple streams to take into account, by bringing their supply chain online manufacturers have been able to reap the benefits of a fully automated and integrated supply chain from the very beginning. In the near future, machines will be programmed to build bespoke products from scratch—products that meet exactly their specific needs. A manufacturing director needs a very specific spare to repair his main production machine—simply click a button to instruct a machine to tailor the spare resulting in production with greater precision than the original. This is not science fiction—the building blocks of this model all exist today. This paper highlights the impact of IT applications in supply chain management activities in various industries around the world.

In this paper, experimental study was conducted to observe the power consumption of different environmental friendly refrigerant mixtures (HC mixture and R401a). It was also observed the effect of working parameters like diameter of capillary tube, working pressures and inlet water temperatures, which affect the power consumption of vapour compression refrigeration system. It was observed that R401a consumed more power than HC mixture and R134a, but there is less mass quantity of HC mixture and R401a is required in the same system. So there is less effect in environment due to leakage.

The hybrid process offers the benefits of the separate processes, and overcomes some of their respective drawbacks, such as the lower tolerance to joint fit up of laser welding, or the higher heat input of arc welding, which increases distortion and subsequent re-work costs. These costs have been estimated to be up to 15-30% of the total labour cost for new construction. Consequently, hybrid welding is already applied in some industries, including shipbuilding, as well as being extensively researched for a variety of materials and industrial applications. For hybrid welding of steel plates, high power output CO2 lasers have typically been used. This paper presents an investigation about hybrid laser-MIG welding in construction steels .An introduction about welding processes involved in...

In addition to this, because of continuous decreasing production the youth of the villages are also migrating in big cities for the employment, resulting decreasing manpower essential to perform various seedbed operations in the villages. Hence, it is the need of time for small farmers having small agricultural land and having less crop production to introduce the cost-effective farm mechanization so that they can improve production rate. Rotavator is the best option available to achieve this landmark as it is already proved that seedbed prepared by using rotavator gives highest benefit to cost ratio. For this experimental study the whole land of 9 acre area is divided into 18 plots of equal size in area. The combination of method of seedbed preparation and use of f...
