Automobile exhaust emission are a dominant source of urban environmental pollution due to movement of high traffic density and believed to have detrimental negative impact on plant growth rapidly since last couple of decades. This study describe the effects of autoexhaust emission on the seed germination and seedling growth behavior of Senna alata (L.) Roxb. (Ringworm) flowering tree growing as street tree in different road side of the city of Karachi. The effects of automobile exhaust emission on the seed germination and early seedling growth performance of S. alata was recorded. The auto emission showed negative effects on seedling height, leaf area (sq. cm), total plant fresh weight, total plant dry weight, root dry weight, stem dry weight, leaf dry weight, root / shoot ratio for fresh weight and root / shoot ratio for dry weight of S. alata growing in polluted sites (Tariq Road, Bahadurabad, Khalid Bin Waleed Road, Gulshan-e-Iqbal Gulshan-e-Iqbal) of city as compared to Karachi University Campus (Cleaner site). The seeds of S. alata collected from the Karachi University campus, which is considered as control site showed better percentage of seed germination and seedling growth as compared to the seeds of the same species collected from the different polluted areas of the city. A high percentage of decrease in seed germination was found for the seeds collected from the Tariq Road, followed by Bahadurabad, Khalid Bin Waleed Road and Gulshan-e-Iqbal Gulshan-e-Iqbal as compared to control. Seedling length was also highly decreased for seeds of same species collected from Tariq Road as compared to control. High percentage of decrease in seedling dry weight was found for seeds of same species collected from Tariq Road, Bahadurabad, Khalid Bin Waleed Road, and Gulshan-e-Iqbal Gulshan-e-Iqbal as compared to control. Root growth of S. alata was significantly decreased in the polluted seedlings as compared to control.\nAccording to tolerance test it was observed that seedling growth of S. alata showed lowest percentage of tolerance to auto exhaust emission were in order of samples collected from Gulshan-e-Iqbal>Bahadurabad>Khalid Bin Waleed Road>Tariq Road as compared to relatively clean area (University campus).
One of basic issues of the sustainable development is the protection of the natural environment. Very important is the waste recycling and the introducing of green technological processes. The use of Fly Ashes (FA), from coal combustion in power plants presents a very important problem in all countries, in which the energy production is based on this fuel. Fly ashes, owing to the spherical shape of their particles, provide consistency, easy placement and compaction of fresh concrete. Phosphogypsum (PG) is a waste product generated by the chemical industry during phosphoric acid production. The processing of PG waste was carried out in waste-free manner by heat treatment with mixing. Biopolymers (BP) were formed on the basis of epoxy resin and fillers in the form of starch or cellulose waste. The study concerned development of composites based on waste FA, PG and BP. Constant Magnetic Field (CMF) characterised by magnetic induction value B = 1 T was an additional parameter improving, under specific conditions, the physical properties of the resultant composites. With respect to absorbability of the tested samples, as a result of exposure to CMF their weight changed by 7,4 % for composites. With respect to flexural strength of the tested samples is concerned, CMF processing caused a change of 11,9 % for homogeneous materials (cement) and of 7,0 % for composites. With respect to compressive strength of the tested samples, CMF processing caused a change of 6,6 % for homogeneous materials (cement) and of 4,6 % for composites. One can apply new composites as: building materials, substructure of the ground, concealed installation insulation layer and polymer materials.
Generation Expansion Planning (GEP) aims to determine the least cost capacity expansion plan to meet forecasted demand inward a pre-defined reliability criterion and emission constraint over a planning horizon. This paper presents the application of Differential Evolution (DE), Opposition-based Differential Evolution (ODE) and Self-adaptive Differential Evolution (SaDE) algorithms to GEP problem, where the power generating system of an Indian state Tamil Nadu is taken as study region. GEP problem has been solved for short-term (6-years) and long-term (12-years) planning horizon by considering least-cost, reliable supply and lowest emission to the environment using DE, ODE and SaDE also validated by Dynamic Programming (DP). GEP problem is solved for seven diverse cases such as, Case 1: Base case, Case 2: GEP with Energy Conservation (EC), Case 3: GEP with high penetration of Renewable Energy Sources (RES), Case 4: GEP with penalty costs on emissions from high emission plants (HEP), Case 5: GEP with energy storage technologies (EST), Case 6: Combination of Cases 2, 3&4 and Case 7: Combination of Cases 2, 3, 4&5. The results simultaneously provide the type and capacity of each type of power plant need to be expanded in each year of the planning horizon at least cost.

Introdução: A presença de morcegos nas áreas urbanas é cada vez mais comum, gerando reclamações aos órgãos de controle de zoonoses. Método: foi efetuado levantamento das reclamações ao Centro de Controle de Zoonoses de Niterói, RJ, no período 2014-2015. Avaliou-se o tempo para a primeira tentativa de visita, o tempo efetivo para a realização da primeira visita, a distribuição espaço-temporal das reclamações, ocorrência de espoliação, tipo de abrigo utilizado e a presença de morcego, vivo ou morto. Resultados: houve aumento na quantidade de reclamações entre 2014 e 2015. A região Praias da Baía teve o maior número de reclamações. Houve melhora no prazo entre a reclamação e a primeira tentativa de visita zoossanitária e entre a reclamação e a efetivação da primeira visita, mas esses ainda são excessivamente longos. Nas regiões mais próximas a visita zoossanitária foi mais rápida e na região mais distante, mais demorada. Apesar do relato de um caso em humano, a espoliação predominou nos demais animais. O principal motivo para reclamação foi a utilização do forro dos telhados como abrigo. Conclusão: A situação encontrada é preocupante quando se considera que acidentes envolvendo morcegos são sempre graves e pela circulação do vírus da raiva no município.
Abstract: The mobile nodes are generally focused for path selection, but path is not perfectly predicted by sender node, it transmitting the data packets continuously. Genuine time routing is difficult for normal path selection scheme, because unfortunately the nodes behavior is changed, it block data packets, and blocks the time, when transmitting data packets. It obtains the inefficient communication. It increase packet loss rate, and reduces network lifetime. So, proposed Efficient routing for unpredictable path (ERUP) method is used to achieve effective communication in mobile network, the current path status is analyzed and after that assign the routing path. Routing path is judged easily by this methods. This does not block data flow and time. Multirate leveraging situation analyzer algorithm is constructed, it analyze the leveraging condition of routing path nodes in various rates, such that rates are resources utilization of nodes. It increase network lifetime and minimize packet loss rate
