Abstract:
This planet is full of diversity amongst the species which were here since the beginning of life, but we can’t say for how long this biodiversity will exist. Due to some very careless actions by humans some species have extinct and many are in danger of getting extinct soon. Agriculture is a leading threat to many species. Almost 80% of threatened species are affected by more than one threat. Biodiversity is very important for us, plants – mainly trees – dominate life on Earth: they account for more than 82% of biomass. Humans account for just 0.01% of biomass. After considering the damage done to the environment governments have taken many steps for protection and conservation through which we are successful to save some species from getting extinct

Abstract:
SBS modified bituminous binder consisting of 4, 4.5, 5, 5.5 and 6 weight % of bitumen was prepared in high speed sheer mixer. Their performance in relation to temperature susceptibility, low temperature cracking, fatigue, rutting in hot condition and workability was tested by penetration, softening point, viscosity and ductility test as per their standard specifications. It is found that with increasing amount of SBS in bituminous binder, the penetration value decreases and softening point increases, which shows improved high temperature performance of modified bituminous binder. The increased value of ductility confirms an improvement in low temperature performance of SBS modified bituminous binder. However, a linearly decreased in penetration index was observed after the blending of SBS with bitumen more than 4% by weight showing the temperature sensitivity. Therefore, the 4% dosages of SBS is the optimized amount to achieve improved performances of SBS modified bituminous binder

Abstract:
Quantum mechanical calculations of energies, geometries and thermodynamic parameters of 6-Amino-1,3- Dipropyl Uracil were carried out by using ab initio HF theory with 6-31+G(d,p) and 6-311++G(d,p) basis sets and density functional theory (DFT/B3LYP) with 6- 31+G(d,p) basis set. The optimized geometrical parameters such as bond length, bond angles etc obtained by HF and DFT calculations are in good agreement with each other. The thermodynamic parameters such as total thermal energy, Enthalpy heat capacity, entropy have also been computed in the temperature range 200-1500 K by using the standard expressions under the rigid rotator harmonic oscillator approximation.

Abstract:
Snail is known to serve as an intermediate host for several species of larval trematodes some of which are highly pathogenic for their second intermediate host i.e fishes. If we want the fisheries development programmes to be successful, we need to intensive research on the fish parasites and their intermediate host. These parasites also provoke remarkable mortality to human and cause serious damages to aquaculture, which is a valuable source of food and employment in developing countries, basically deals with the studies on effect of parasite i.e. cercariae that were found in various water bodies of Meerut region infecting the host B. bengalensis and L.luteola. Recent investigations have shown that some of the molluscs are sources of important bio medical compound. The World Health Organization (WHO) is therefore, paying special attention to this dynamic host-parasite interaction of larval trematodes and snail control. Although the effects of digenetic trematodes on their vertebrate hosts have been studied, comparatively little attention has been paid towards the host-parasite relationship between the larval trematodes and their molluscan hosts.
