Research ArticleOpen accessEvery word in the titleBioinformatics Analysis of Xyloglucan Endotransglycosylase/Hydrolase (XTH) Gene from Developing Xylem of a Tropical Timber Tree Neolamarckia CadambaTiong Shing Yiing, Ho Wei Seng, Pang Shek Ling, Ismail JusohThis study reported the isolation and in silico characterization of a full-length Xyloglucan endotransglycosylase/Hydrolase (XTH) cDNA from Neolamarckia cadamba, an important tropical light hardwood plantation tree species. XTH is considered as a key agent to regulate cell wall expansion and is believed to be responsible for the incorporation of newly synthesised xyloglucan into the wall matrix. The full-length of NcXTH … …Current Research in Bioinformatics, Vol. 3, Issue 1 · 6 Jan 2015 · 7,431 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleASSESSING THE EFFECTS OF LOGGING ACTIVITIES ON AVIAN RICHNESS AND DIVERSITY IN DIFFERENT AGED POST-HARVESTED HILL DIPTEROCARP TROPICAL RAINFOREST OF MALAYSIAM. N. Rajpar, M. ZakariaLogging activities have encroached into the hill dipterocarp tropical rainforest area since the lowland dipterocarp forests have decreased in size. Hill dipterocarp tropical rainforest is rich in habitat diversity and provide a variety of resources for avian species such as food, habitat and shelter. Therefore it is important to examine the logging effects of hill dipterocarp rainforest on avian species. … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 15 Jul 2014 · 7,584 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessing Soil Fertility Status of Rehabilitated Degraded Tropical RainforestAiza Shaliha Jamaluddin, Arifin Abdu, Hazandy Abdul-Hamid et al.An assessment of forest rehabilitation program in relation to soil fertility status by using soil indices could provide fundamental information on soil suitability for species preferences and improve the effective technique for future rehabilitation program in tropical rainforests. This study was conducted in order to characterize the soil properties and identifying the soil fertility status of rehabilitated and secondary forests. … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 19 Jul 2013 · 8,461 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Analysis on 16-Channels Wavelength Division Multiplexing in Free Space Optical Transmission under Tropical Regions EnvironmentSalasiah Hitam, Siti Norziela Suhaimi, Ahmad Shukri Mohd Noor et al.Problem statement: Wavelength-Division-Multiplexing (WDM) is a promising technique for meeting the growing demand for increased bandwidth and various types of services in the optical access network. For wide area or metropolitan networks, fibers are deployed to provide huge bandwidth. In access networks, the fiber-to-the-home will partially solve the last mile problem. However, some environmentally sensitive area such as housing areas, … …Journal of Computer Science, Vol. 8, Issue 1 · 2 Nov 2011 · 10,365 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNo Damage of Dietary Dried Fermented Ginger Diet without Antibiotics on Growth Performance in Broilers Reared in Tropical AreaDuddoa Khonyoung, Koh-en Yamauchi, Tonglian Buwjoom et al.Problem statement: The experiment was carried out to determine whether the dietary Dried Fermented Ginger (DFG) has no affecting damage on broiler growth performance and can also be applicable in tropical and subtropical area using basal diets without antibiotics. Approach: Three hundred and fifty 7-d-old Arbor Acres broiler chicks were divided into one basal diet group (control) and 6 experimental … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 6 Aug 2011 · 7,948 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIdentification a Novel Raw-Starch-Degrading-α-Amylase from a Tropical Marine BacteriumZeily Nurachman, Alfredo Kono, Ocky Karna Radjasa, Dessy NataliaProblem statement: Bacteria from the surface of the tropical marine hard coral Acropora sp. were screened for producing raw-starch-degrading-α-amylase. Approach: Based on its 16s rDNA sequence, a bacterium that produced the highest amylolitic activity was identified as Bacillus amyloliquifaciens ABBD. The bacterial isolate secreted a α-amylase extracellularly and then the enzyme was partially purified by ammonium sulfate precipitation followed by … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,337 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Tropical Peat Swamp Forest Clearing on Soil Carbon StorageAhmad Shukri Mat Nuri, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidAbstract: Problem Statement: Forest clearing in Tropical Peat Swamp Forest (TPSF) will affect forest soil carbon storage. Thus this study is essential to determine whether the effect of clearing of forest does to the nature of soil forest concentrating on soil carbon storage. The objectives of this study were to analyze carbon storage values in logged and clear cut TPSF … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,941 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLeptospirosis in the Tropics: When Prevention Doesn't Easily Sell as a Ton of CureRoger Lee MendozaProblem statement: Human leptospirosis -- the most widespread zoonotic disease -- thrives in tropical and subtropical climates. It is seldom addressed ex ante or prior to an outbreak or expected outbreak by governments of high-risk countries. Whether common, post-exposure treatment with antimicrobial drugs is more cost-efficient than reducing animal reservoir populations was the overarching question that guided this study. A … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 8,381 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Logging Operation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Since heavy machinery are used in the logging operation activity for extracting the logs on sensitive forest site with peat soil, environment destruction should be the other concern during its processes especially on its important function as soil carbon storage. The objective of this study was to determine whether logging operation affect soil carbon storage of a tropical … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 8,035 accessesView PDFCite
