  Abstract It is well established that Orange peeled oil biodiesel (OPOB) is a suitable fuel in Compression Ignition (CI) engines because of its compatible physicochemical properties with diesel. Literature is however sparse on its emission characteristics in CI engines majorly because few investigations have been done due to seemingly difficult and time-consuming experiments. On this strength, this work first carried out experimental investigations on carbon monoxide (CO), unburned hydrocarbon (UHC), oxides of nitrogen (NOX) and smoke of orange peel oil based biodiesel in single cylinder, four stroke CI engine; and afterwards applied the power of artificial neural networks (ANNs) prediction model to predict to the full-scale CO, UHC, NOX, and SMOKE values of the CI engine. Brake load, orange oil-diesel mixture percentages and engine speed were the inputs of the ANN while Levenberg Marquardt (trainlm) and scaled conjugate gradient (trainscg) were the training algor...

  Abstract Soil salinity is one of the most important abiotic factors that adversely effect on plant growth. In addition, nursery and greenhouse industry is under pressure to recover and recycle fertilizer solution and wastes. Most of these contains significantly higher salt concentrations that could cause harm to susceptible species of plants. Rose plants are the most attractive plants in all our world. Although, the roses face serious salt stress. Globally, soil salinity is naturally occurring or by the usage of poor quality of water and the other activities of humans or use of excessive amount of fertilizer applications. Although, the level of salts tolerance among various cultivars and species can be different in roses. In this review paper, we will discuss the responses of roses to salinity and ways to combat salinity in roses production.

Short Communication Multiple levels of government must play complementary roles in mitigating climate changes (Francis and Feiock 2009; Ostrom 201#), but city level engagement and action are particularly critical for two reasons. First, urban areas are the primary source of GHG emissions worldwide. For example, in the US urban areas hold over three-fourths of the population and account for about 80% of global primary energy use and greenhouse gas (GHG) emissions [1]. Second, cities have the potential to significantly influence environmental and problems since they have primary responsibility for the local land use and building decisions that are critical to sustainability efforts. In many countries’ cities have stepped up to address climate and GHG mitigation issues. City leadership in climate protection is especially visible in the US due to the absence of action by the national level government, but cities have been leaders in nations across the globe (Krause et al. 2...
