Partial Replacement of Toluene Diisocyanate (TDI) on Mechanical Properties of Old Newspaper Filled Diphenylmethane Diisoeyanale (MDI) Foam Composites

The mechanical properties of partial replacement of toluene diisocyanate (TDI) in diphenylmethane 4,4’-diisocyanate of old newspaper (ONP) foam composite based on polyurethane (PU) was investigated. The results indicate that an increase of ONP filler content leads to an increased compressive strength, elastic modulus and hardness. At constant ONP content, foam composites produced by partial replacement of TDI in MDI result in higher values of hardness, compressive strength and elastic modulus compared to the ONP foams control

Plasmid DNA Analysis of Pasteurella multocida Serotype B isolated from Haemorrhagic Septicaemia outbreaks in Malaysia

A total of 150 purified isolates of Pasteurella multocida serotype B were used (Salmah, 2004) for plasmid DNA curing experiment to determine hyaluronidase activity, antibiotic resistance pattern (ARP) and mice lethality test (LD50) for their role of pathogenicity. A plasmid curing experiment was carried out by using the intercalating agent; ethidium bromide and rifampicin, where it was found all the plasmids had been cured (plasmidless) from Pasteurella multocida. All of these plasmidless isolates maintained their phenotypic characteristics. They showed the same antibiotic resistancepattern as before curing, produced hyaluronidase and possessed lethality activity in mice when injected intraperitoneally(i.p). Based on this observation, the antibiotic resistance, hyaluronidase activity and mice virulence could probably be chromosomal-mediated. Plasmids were detected 100% in all P. multocida isolates with identical profile of 2 plasmids size 3.0 and 5.5 kb. No large plasmids could be detected in all isolates. Since all the isolates appeared to have identicalplasmid profiles, they were subjected to restriction enzyme(RE) analysis. From RE analysis results obtained, it can be concluded that the plasmid DNA in serotype B isolates are identical. Only 4 of 32 REs were found to cleave these plasmids with identical restriction fingerprints; BglII, HaeIII, RsaI and SspI. From RE analysis results, it can be concluded that the plasmid DNA isolates are identical. This plasmid might not played any role in pathogenicity of Pasteurella multocida serotype B, however this information is important for the construction of shuttle vectors in genetic studies of the pathogenicity of haemorrhagic septicaemia(HS)

Gambaran Paparan Debu dan Fungsi Paru pada Pekerja Pembuatan Perabot Rumah Tangga di CV Kochi Sohor Terjun Medan Marelan Tahun 2013

Description of dust exposure and lung function in workers home furnishings maker on CV Kochi Sohor Terjun North Sumatera in 2013. The dust exposure in the working environment indirectly may result in variously disorder on health, one of them is a respiratory disorder that since then it is going to impact one's productivity. Noted that respiratory disorder might be influenced by amount the dust level around working environment and the worker's attitude over wood's dust exposure perhaps by using one's self protecting tool (APD), working service, previously illness history, smoking history of the worker. This study aims to know whether the influence of the wood's dust exposure against the function of wood of those workers in furniture with informal sector on CV Kochi Sohor Terjun Medan Marelan. The research adopted an description with sectional across approaching. It is involved 6 samples taken out population presented while conducting the field research. In collecting the data, the writer provided questionnaire, with tester of dust level in a High volume sampler, and the tool to measure the function of lungs there used Spirometer Sibelmed Datospir Mod 120B. The result of this research seen by a 2 working area measured that not exceeding the total dust level above quality standard of the Area of wood folding 4.53 mg/m3, and the refinery site 2.38 mg/m3 (< 10 mg/m3 NAB). The respondent got lowering function of lungs in a light restrictive 4 people and another 1 got reducing function of lungs in moderate restrictive. The result of bi-variant indicated no found any relation between the uses APD, working service, previous illness history, age, smoking history with reduced function of lungs. It is expected having a health check over all workers whose got reducing function of lungs or not and for not getting deteriorated function of lungs

Pineapple peel industry determination with weighted location method

This study discusses alternative fuels to replace gasoline with bioethanol. Bioethanol can be produced including pineapple, where the peel can be used to be converted into bioethanol instead of gasoline. The use of pineapple peel for small-scale production in this study was the main focus, so that the community would get benefit from the economic value. The community to use pineapple peel is the main concern, to get information about the capacity of an area. Measurement of capacity is carried out by taking into account transportation, raw material, land, energy, labour, waste, and market factors. The assessment was carried out on five zones of pineapple farming using analytical hierarchy process (AHP). Each area is determined by its coordinates, then multiplied by the weight of each region produced. The calculation results show that the determination of area was chosen to be a smallscale bioethanol production area concerning with dependent on the policy, raw materials, and transportation factor, it show that policy factor must be exist to support the operation of bioethanol industry with pineapple peels material

Mechanical characteristics of groundnut shell particle reinforced polylactide nano fibre

ABSTRACT The PLA-groundnut shell solution is electrospun to produce nanocomposite fibre. The spinneret containing the composite solution was placed 24.7 cm away from the aluminium collector, tilted at an angle of 30 °, and the solution flow rate kept at 1 mL/min. Groundnut Shell particle (GSP) weight fraction used was varied from 3 - 8 wt. %. Particle reinforced nanofibres were formed on the collector from the composite solution at 26 kV. These nanofibres were subjected to tensile test and the result indicates that at 6 wt. % untreated GSP reinforced fibre possessed the best tensile stiffness of 24.62 MPa. This corresponds to 2.201 % increase in Modulus of Elasticity over the unreinforced PLA (1.07 MPa). The 7 wt. % treated GSP fibre showed the least stiffness (0.33 MPa), which is 69 % reduction over that of unreinforced fibre. PLA fibre reinforced with 5 wt. % untreated GSP displayed best blend of properties over the unreinforced with increase of 286 % (4.43 x 10-4 HB), 1,502 % (1.07 MPa), 286 % (0.22 MPa), 6.8 % (0.05 J) and 1,081 % (~ 0.15 MPa) in hardness, stiffness, UTS, energy at break and stress at break respectively. However, ductility decreased by ~33.3 % when compared to the unreinforced (18.27). The 5 wt. % untreated GSP PLA reinforced fibre showed the highest UTS (0.855 MPa). The micrographs showed beads on reinforced fibres, while the virgin PLA showed no beads

Aedes larval population dynamics and risk for dengue epidemics in Malaysia

Early detection of a dengue outbreak is an important first step towards implementing effective dengue interventions resulting in reduced mortality and morbidity.A dengue mathematical model would be useful for the prediction of an outbreak and evaluation of control measures.However, such a model must be carefully parameterized and validated with epidemiological, ecological and entomological data.A field study was conducted to collect and analyse various parameters to model dengue transmission and outbreak.Dengue-prone areas in Kuala Lumpur, Pahang, Kedah and Johor were chosen for this study.Ovitraps were placed outdoor and used to determine the effects of meteorological parameters on vector breeding.Vector population in each area was monitored weekly for 87 weeks.Weather stations, consisting of a temperature and relative humidity data logger and an automated rain gauge, were installed at key locations in each study site.Correlation and Autoregressive Distributed Lag (ADL) model were used to study the relationship among the variables. Previous week rainfall plays a significant role in increasing the mosquito population, followed by maximum humidity and temperature. The secondary data of rainfall, temperature and humidity provided by the meteorological department showed an insignificant relationship with the mosquito population compared to the primary data recorded by the researchers.A well fit model was obtained for each locality to be used as a predictive model to foretell possible outbreak
