 Abstract

A series of (4Z)-4-(Arylidene)-2-(2-Hydroxyphenyl)oxazol-5(4H)-ones were synthesized by condensation of substituted hippuric acid with different aromatic aldehydes in the presence of fused sodium acetate, acetic anhydride in catalytic amount, ethanol as solvent under reflux conditions.All the synthesized compounds were confirmed and characterized by using various spectral techniques like IR, H1NMR, C13NMR, and mass spectral studies. All the synthesized oxazolone derivatives displayed moderate to potent antibacterial activity.

 Abstract

The fourth order boundary value problems arise in the mathematical modeling such as visco-elastic and inelastic flow problems, bending of beams and plates deflection theory , beam element theory and many applications of engineering and applied sciences. Computing such type of boundary value problems analytically is possible only in rare cases. Many researchers worked for the computational solutions of fourth order boundary value problems. In the present work, we attempted to present a simple finite element method which involves Galerkin approach with quintic B-splines as basis functions to solve a fourth order boundary value problem with suitable boundary conditions.

 Abstract

The study of migration or the fate of the contaminant miscible in ground water from waste site, dumping yards or landfills is essential for preparation of ground water contamination models. Numerical methods are generally adopted to measure the key parameters at a small scale as it is time consuming and costly to determine them in the field and used for quantifying flow and transport in large scales in in-situ conditions applied to simulate real contaminant transport models. These methods need a number of key parameters such as porosity, hydrodynamic dispersion, velocity of contaminant flow and Temperatures. The main aim of this research is to evaluate the nonlinear variation of the Distribution coefficient with parameters like porosity, power factor and bulk density based on detailed experimentation carried out on physical models in the laboratory and development of a suitable and appropriate numerical model. The batch and column tests were conducted to evaluate the distribution coefficient and sorption capacity.

 Abstract

Traffic congestion is becoming a serious problem in Hyderabad like any other city in India. Therefore, there is pressing and growing need to measure congestion levels in a consistent manner and it is needed to improve the road facilities in order to connect different areas with no loss of time. A multi-disciplinary approach is needed in understanding the problem and providing solutions. Hyderabad is the fifth largest city of India with a total extent of 1868 sq.km. A huge amount of traffic moves daily and in order to divert the highway traffic bypassing through the city and to reduce the travel time and to connect all the places around the city without connecting to inner ring road, an outer ring road is essential. The backbone of any successful traffic management system for a metropolis is reliable, accurate and real time data. Traffic flowing, travel time and traffic increments are the three most important factors considered in TMS for analysing and predicting the traffic and controlling congestions. It is observed that major congestion problems are caused due to poor network of roads. This study presents manual counting of traffic flowing on ORR as well as at underpasses and the traffic is predicted for future years. The main aim of our project is to de-congest metropolitan area and inner ring road and to meet future demand. A comparative statistical analysis was performed on traffic predictions. Information about ITS is specified which helps in decongestion of traffic on ORR due to increased vehicular traffic. Moreover, our study conveys the importance of transportation engineering in our day to day life.

 Abstract

Drought stress is considered as one of the most adverse abiotic stresses which is a threat to majority of the plant growth and productivity. Therefore, the aim of the present study was to identify the drought tolerant genotype/s of Cluster bean (Cyamopsis tetragonoloba L.Taub.) for the semi-arid regions. Abiotic stresses have considerable influence on biomass and seed yield parameters of crop plants. A field experiment was conducted to evaluate the moisture deficit stress on biomass and seed yield parameters of three cluster bean genotypes RGC-1025, RGC-936 and HGS-563 during winter season 2014. The stress was imposed during the initiation of flowering stage and the observations were recorded at the time of harvest for growth, biomass and seed yield parameters. All the selected genotypes recorded reduction under stress condition as compared with well watered condition for morphological, biomass and seed yield traits, however the magnitude of reduction varied with genotype. Among the three genotypes, the total biomass at harvest was highest with HGS-563 while with RGC-936 under stress. The seed yield was highest with RGC-936 under both moisture levels while HGS-563 recorded lowest seed yield as well as highest reduction with stress. Among all the three genotypes assessed, the genotype RGC-936 performed best in both moisture levels for biomass and seed yield parameters.

 Abstract

When poor quality soil is encountered at construction site, the structure can be designed accordingly or the unsatisfactory soil can be replaced with a suitable soil borrowed from nearby area. Another option is to modify the properties of the existing soil so that it meets the design requirements. This last alternative has led to the development of soil stabilization techniques. Cementing method of soil stabilization is an established procedure of improvement of ground used as sub-grade for pavements. In view of this, apart from the conventional cement, several commercial stabilizers have emerged in the last few years. In line with this, an attempt has been made in the present study to evaluate the effectiveness of one of the new commercial stabilizers viz., Zycobond, Terrasil manufactured by Zydex industries. In this paper, the economic analysis has been done on both flexible and rigid pavements. These cost analyses play a great role on the decision-making stages in selection of pavement types. The pavements were designed under different traffic conditions and soils treated with zycobond and Terrasil. Thickness design of flexible pavement has been conducted as per the IRC:SP:72 2015. Costs are calculated and construction costs have been determined for both flexible and rigid pavements according to BoQ based on MORTH and compared
