The performance of a laboratory scale upflow anaerobic sludge blanket (UASB) reactor and its posttreatment unit of sand-chemically carbonized rubber wood sawdust (CCRWSD) column system for the treatment of a metal contaminated municipal wastewater was investigated. Copper ion contaminated municipal wastewater was introduced to a laboratory scale UASB reactor and the effluent from UASB reactor w...

Transparent wood (TW), a new type of composite material with good optical transmittance and excellent mechanical properties, has attracted great interest in recent years. In this study, hydrogen peroxide strategy was used on rubber (Hevea brasiliensis Muell. Arg) to eliminate lignin hemicellulose. Subsequently, delignified combined each three impregnants refractive index similar that cellulose ...

This study used an experimental method to investigate the effects of various stylus tip materials on the handwriting input performance of handheld devices. The stylus tip materials used in this study were stainless steel, plastic, wood, and rubber. Performance assessment indicators were Chinese character handwriting input speed, accuracy, and ease of writing. The results showed that plastic sty...

During combustion of solid fuels in the material inlet end of cement rotary kilns, local reducing conditions can occur and cause decomposition of sulfates from cement raw materials. Decomposition of sulfates is problematic because it increases the gas-phase SO2 concentration, which may cause deposit formation in the kiln system. SO2 release from cement raw materials during combustion of solid f...

Table tennis, which emerged in the late 1800s, has changed and developed with equipment development,as many sports. In early days, table tennis was played parchment-covered long-handled rackets corkor rubber balls. The game started to change invention of hard rubber-coated racket 1930s, thetable also spread composite materials. A blade made wood can consist ofa single layer, or it mostly consis...

Rubber wood often exhibits dimensional instability during use, which seriously hinders its widespread application. In order to enhance the stability of rubber wood, a two-step method was employed in this study modify using two plant-derived compounds, namely sucrose and tung oil. Samples treated alone with or oil were also prepared. The water absorption, stability, thermal modified untreated ev...

The use of fiber board is increasing due to limited supply timer wood. This study investigated the suitability medium density (MDF) made from rubber wood for household and industrial use. Rubber was collected Bangladesh Forest Development Corporation (BFIDC), Chattogram. Single layer boards were fabricated by five different densities, such as 700, 725, 750, 775 800 kgm-3. mechanical physical pr...

The used tyre rubber, scrap ceramic tiles and wood dust are largely dumped into landfills, which create environmental pollution to the surrounding. recycling of rubber is very limited, but it has good property absorb impact energy. Hence, these materials prepare composite in present work. Composite were prepared by resin transfer moulding method with different weight percentage particles. tensi...

The RAMP Anthrax Test Cartridge for detecting Bacillus anthracis was validated for use in the field for detection of B. anthracis spores in visible powder residues on 7 nonporous environmental surfaces. Six teams of trained first responders and civil support personnel in Class C personal protective equipment sampled visible powder residues on plastic, stainless steel, ceramic tile, wood, rubber...

This study presents a large-scale monitoring of marine litter performed in the joint Norwegian–Russian ecosystem monitoring surveys in the period from 2010 to 2016 and contribute to documentation of the extent of marine litter in the Barents Sea. The distribution and abundance of marine litter were calculated by recordings of bycatch from the pelagic trawling in upper 60m, from bottom trawling ...
