 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : “Rodent Biodiversity Human Health and Pest Control in a Changing Environments” Rodent-Borne Zoonotic Viruses in Southeast Asia) ผู้เขียน: Blasdell Kim, Herbreteau Vincent, Henttonen Heikki, Phonekeo Darouny, Hugot Jean-Pierre, Buchy Philippe สื่อสิ่งพิมพ์:pdf AbstractArenaviruses and hantaviruses circulate among the rodent populations of southeast Asia, and can occasionally be transmitted to humans. The latter virus has been identified in human patients in southeast Asia, although the former has not. The case fatality rate due to hemorrhagic fever with renal syndrome (HFRS), caused by hantaviruses and carried by murine rodents, varies between 2–12%, while the case fatality rate due to the arenaviral lymphocytic choriomeningitis virus (LCMV) is lower than 1%. Great care must be taken to avoid infection in pregnant women by LCMV, where serious complications can occur. At present, treatment other than supportive therapy is unavailable for LCMV. A range of vaccines exists in Asia, or are under development for the prevention of hantavirus infection, while ribavirin can help in the early phase of an acute illness. With changing climates and land use and rapidly increasing globalization, it is likely that the situation regarding these zoonotic viruses will change, resulting in an increase in human infections. Few studies have been carried out in this region, particularly in terms of LCMV. More are needed to establish the rates of infection by these agents (and for other potential rodent-borne zoonoses), both in their rodent hosts and in humans, so that they can be used as a baseline to monitor any changes that may occur. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Preparation and Characterization of Cassava Fiber-Based Polypropylene and Polybutylene Succinate Composites) ผู้เขียน: ดร.รัตนา ตันฑเทอดธรรม , Thierry Tran, สุนีย์ โชตินีรนาท, Byoung-Ho Lee, Se-na Lee, ดร.กล้าณรงค์ ศรีรอต, รองศาสตราจารย์ , Hyun-Joong Kim สื่อสิ่งพิมพ์:pdf AbstractCassava root fiber was used as a bio-reinforcement in a polymer composite. A composite of polypropylene (PP) and polybutylene succinate (PBS) with cassava root fiber was prepared on a twinscrew extrusion. Maleic anhydride-polypropylene (MAPP) compatibilizer was used to improve the interfacial strength between the fibers and the polymer matrix. The effects of untreated fiber content and compatibilizer on the mechanical properties of composite were investigated. An increase in fiber loading increased the Young’s modulus and flexural modulus, indicating higher stiffness in the fiber-filled composites, whereas the tensile strength and flexural strength decreased. The addition of MAPP compatibilizer in the PP composite with 50% fibers improved the flexural strength to a higher level than pure PP, therefore giving rise to a stronger but less flexible material. Studies with a scanning electron microscope revealed better interfacial adhesion between the fibers and the polymer matrix in the composite containing MAPP compatibilizer. Thermogravimetric analysis showed that the thermal stability and degradation temperature of PP composites increased with the presence of MAPP, suggesting enhanced interfacial interaction and compatibility due to the treatment of compatibilizer. |
