【Title】【Author】【Addresses】1The tree root distribution pattern and biom..s of seventeen year old trees of Grewia optiva, morus alba, Celtis australis, Bauhinia variegata and Robinia pseudoacacia were studied by excavation method. B. variegata roots penetrated to a maximum depth of 4.78 m, whereas, m. alba roots were found down to 1.48 m depth. Lateral spread was minimum in B. variegata （1.10 m）and maximum inR. pseudoacacia （7.33 m）. maximum root biom..s of 6.30 kg was found in R. pseudoacacia and minimum （2.43 kg） was found in m. alba. For four species viz.,G. optiva, m. alba, C. australis andR. pseudoacacia, 68%-87% root biom..s occurred within top 0-30 cm soil depth, but forB. variegata this was only45%. The soil binding factor was maximum in G. optiva and minimum in B. variegata. Soil physico-chemical properties also showed wide variation. The study suggests thatB. variegata with a deep root system is the most suitable species for plantation under agroforestry systems. R. pseudoacacia and G. optiva with deep root systems, more lateral spread and high soil binding factor are suitable for plantation on degraded lands for soil conservation.

This study was to investigate growth performance, rumination development, rumen fermentation and feed digestion in young calves provided high volumes(about 20% of calf birth weight) of milk with or without forage inclusion and how these parameters correlate with each other. Immediately after birth,160 newborn Holstein female calves(41.6 ± 4.2 kg of initial BW) were random.. divided into 2 treatments: 1) starter(CON, only starter) and 2) starter and hay(HAY, both starter and hay). The calves were fed their respective experimental diets from.. 4 to 84, after which they were all introduced to similar diets until the end of the experiment on d 196. Treatment had no effect on growth and structural measurements throughout the experimental period. However, treatment had an effect on the other parameters, mainly during the post-weaning period.

Aluminium phosphide (AlP) is used as a fumigant and also som..imes misused for suicidal attempts in India, due to its easy availability. The effect of phosphine, the gas that is liberated when AlP com.. in contact with moisture, is well documented in the literature. However, the effect of AlP in its native form on animal models is not well cited. In this study we examined the acute toxic effect of AlP in rats. Oral LD50 of AlP for male and female rats were found to be 14. 13 and 11. 89mg/kg, respectively. Oral administration of an AlP dose of 0. 80 LD50 resulted in significant increases in the level of plasma glutamic oxaloacetic transaminase,alkaline phosphatase, glucose and urea in rats of both sexes. Hemoglobin level and packed cell volume also increased significantly 6h after administration. Body weight was reduced but the organ to body weight ratio of lung, liver, spleen, kidney and testes remained *** changes induced by AlP during 24-48h induced hemorrhage, congestion and mild to moderate atrophy of various cellular com..nents of visceral organs. The study showed that the acute toxic effect of AlP may be due to hypovolemic shock. Female rats were found to be more susceptible than were males.

Wireless sensor networks （WSNs） consist of sensor nodes that broadcast a message within a network. Efficient broadcasting is a key requirement in sensor networks and has been a focal point of research over the last few years. There are many challenging tasks in the network, including redundancy control and sensor node localization that mainly depend on broadcasting. In this paper, we propose a broadcasting algorithm to control redundancy and improve localization （BACRIL） in WSNs. The proposed algorithm incorporates the benefits of the gossip protocol for optimizing message broadcasting within the network. Simulation results show a controlled level of redundancy, which is up to 57.6% if the number of sensor nodes deployed in a 500 m×500 m area are increased from..0 to 500.
