BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation and results from environmental factors and genetic factors. Although cigarette smoking is a major risk factor, other environmental exposures can influence COPD. The purpose of this study is to investigate the clinical characteristics of COPD according to the history of environmental exposure. METHOD...

<p><em>Utilization of palm waste in the form charcoal briquettes makes fuel more efficient and a better form. Thus, briquette with sugar is solution or alternative to solving problem caused by trees. This research was conducted aim knowing effect pre-heating on pyrolysis process biomass gas fraction, bio-oil char. study used an experimental method Mechanical Engineering Education La...

Combustion characteristics of rice husk and coconut shell briquettes have been investigated with a view establishing its suitability as an energy source. The were collected carbonized in furnace charcoal (RHC) (CSC). These further down sized sieved to 2.5 mm particle size. RHC CSC mixed proportions 50:45, 60:35, 70:25, 80:15, 90:5% by weight respectively, 5% cassava starch used binder for all t...

binders are of prime importance in the agglomeration of iron ore concentrates. in this research, strength and density of briquette produced from the magnetite concentrate of gol-e-gohar were investigated using different binders at various applied pressures. the results showed that peridor was the most effective binder relative to bentonite and lime. for all types of binders, the increase in bin...

Abstract The purpose of this study was to find the optimal parameters briquette making process (particle size and pressure), where optimization carried out based on values physical properties, namely density, elastic modulus ultimate tensile strength. method used in vary particle palm shell charcoal waste with sizes 40, 60, 80 100 mesh mixed chopped LDPE plastic a 0,5 x cm, starch adhesive wate...

“One way of making efficient use existing resources is briquetting. Briquetting involves collecting combustible materials that are not usable due to lack density, and compressing them into solid fuels convenient shape can be burnt like wood or charcoal”. “Biomass briquette one the proven ways generating energy from waste”. “Fossil fuels, natural gas major sources for in Nigeria today”. “The exc...
