High alumina castables: A comparison among various sol-gel bonding systems Singh, Akhilesh Kumar; Sarkar, Ritwik A comparison among various sol-gel bonding systems has been done for high alumina castable refractory. Four different sol systems, namely alumina, boehmite, mullite and spinel, have been synthesized and used individually as sole binder in high alumina castable system with particle size distribution coefficient of 0.23 as per Dinger and Funk model. The castable compositions were processed conventionally and properties were evaluated after heat treatment at different temperatures. These developed sol containing compositions were also compared against commercially available silica sol containing composition prepared under exactly similar conditions. Mullite sol bonded composition showed higher cold strength, whereas spinel sol resulted in better hot properties. Improved thermal shock resistance against commercial sol binder was observed in spinel and mullite sol containing compositions, may be associated with the micro-cracking effect produced from the thermal expansion mismatch. The slag corrosion resistance was also observed better for the spinel sol containing composition. The commercial silica sol bonded compositions showed higher strength due to its higher solid content but resulted in inferior hot and corrosion properties.

Application of Queueing Theory to Airport Related Problems Jhala, Nityangini; Bhathawala, Pravin Air traffic, worldwide, keeps growing strongly, creating critical capacity situations and traffic congestion. Large delays are suffered by airlines, passengers and airport authorities alike. When a rough estimate is needed, the results of queuing theory can be used to analyse airport runway systems, but when airports are too congested or a more realistic description of the system behaviour is necessary, Careful analytical planning is needed in advance of facilities and systems design, as the results of congestion could be both serious and expensive to travellers, airlines, and airports.

Analysis and Application of Queuing Theory in Supermarkets Jhala, Nityangini; Bhathawala, Pravin Waiting lines or queues are a common phenomenon in life, especially in the province of organizations that are for profit making. Queues are common in such places as petrol or filling stations, supermarkets stores, clinics, hospitals, motor parks, manufacturing firms, to mention a but a few. An interesting aspect of queuing process resides in the measures of its system’s performance, especially in terms of average service rate, systems, utilization and the costs implied for a given capacity level. This paper examines efficient queue management in XYZ supermarket as case study. One of the expected gains from studying queuing systems is to review the efficiency of the models in terms of utilization and waiting length, hence increasing the number of queues so customers will not have to wait longer when servers are too busy. In other words, trying to estimate the waiting time and length of queue(s), is the aim of this study. Through this, we will try to estimate that at given time how many servers will be required so that the total cost is optimized.

Evaluation study of micropropagation stages of patchouli plant INAMPUDI, SAILAJA; BHOSALE, LAXMAN; ROHINIKAR, ANURADHA; IVVALA, ANAND; KOMAL, C. GONJARI; GANGAVANE, AJIT An effective means for rapid multiplication of plant species of clonal origin is micro propagation. Various in vitro studies have been reported on different species of patchouli, one such method of propagation that can be usefully employed to produce relatively uniform plantlets in a short time is via in vitro culture but there is limited effort to study direct organogenesis, which supports cultivation by providing true type plants in large numbers. Therefore this study determines the effect of different concentrations of growth hormones on patchouli, micropropagation and rapid multiplication stages of patchouli plant within a short time with good results of micropropagation stages for regeneration of patchouli were successfully initiated.
