ASSESSMENT OF ENVIRONMENT CONSCIENCE CONSTRUCTION PRACTICES IN PAKISTAN USING SIGNAL TO NOISE RATIO
...sp;is a source of carbon emissions and solid waste as well. The positive impact is more of a community or region based, whereas its contribution to climate change has a global spread. For years, environment-friendly construction, green buildings, lean construction, and sustainable construction has been portrayed as a possible alternative. However, the success factors for environment conscience construction differs in different regions. Identific...

MACROSCOPIC SPRAY CHARACTERISTICS OF DIESEL AND BIODIESEL-DIESEL BLEND: AN EXPERIMENTAL COMPARISON
...l of engine exhaust emissions and efficiency optimization. This paper investigates the effect of injection duration and ambient pressure on spray development, spray tip penetration (L) and cone angle (β) of biodiesel-diesel (20%/80%: v/v) blend (B20) and diesel, and hence compares the quality of the fuels. Both ‘L’ and ‘β’ play a key role in the fuel evaporation and mixing of fuel with air in the combustion...

Heavy Metals (Pb and Ni) Pollution as Affected by the Brick Kilns Emissions
...The effect of brickworks emissions on heavy metal content of soil and plants around the brick kiln chimneys was studied in 2009-2010. The research was carried out on Peshawar Ring Road’s south direction between chimneys of bricks preparation that were named A and B with distance of 300 m. The kilns were positioned such that Southern direction of chimney of A was north for the chimney B. A total of 36 (18+18) soil and wheat leaf samples were collected in ...

...y, and fecal NH3 and H2S emissions compared with CONT diet. There were no differences in performance parameters between the use of the single product and the combination. In general, a diet containing a combination of PROB and ORAC had larger effects on parameters observed than a diet containing either PROB or ORAC.

...ted to excessive methane emissions that have a negative impact on the environment. It requires special attention to the loss of feed energy from the methane gas formation process. Public fretfulness agreed that the gas produced by ruminants is a big factor in the effects of global warming. Alternative the decrease in methane production from ruminants is by utilizing secondary metabolite compounds in plants. These studies are interesting to be continued and exp...

Adding hydrogen (H2) in NG can be a solution to lean NG combustion limits. Herein, the experimental research was accomplished to analyze the effect of hydrogen blending on the combustion, emission, and performance aspects of NG EQD210N-20 engines. The engine was run at six different working conditions whi...

An in vitro experiment was conducted to determine the effect of adding three different clay minerals in four levels of each, as follows: humic acid (0.0, 0.5, 1.0, and 1.5%); zeolite (0.0, 1.25, 2.5, and 5%); or bentonite (0.0, 1.0, 2.0, and 3.0 %) with three different protein sources, (soybeans, sunflowers, or cottonseed meals) on a dry matter basis. All rations were incubated in a rumen cult...

Thus, the objective of the current study was to evaluate aluminum chloride (AlCl3) as an acidifier to reduce odorous compounds from pig slurry, as well as microclimatic temperature variations and pig eye conditions in pig indoor facilities during storage. A total of 360 crossbred fattening pigs ([Landrace × Yorkshire] × Duroc]) with an average body weight of 60.5 ± 1.21 kg, were randomly di...

Air samples both from indoor and outdoor along with the litter and feed samples of ten poultry houses were collected from the outskirts of Lahore, Punjab, Pakistan. Poultry farms were varied in feed and grouped into three categories: Group A (using Feed A), Group B (using Feed B) and Group C (using Feed C). All collected samples we...
