Opportunities And Obstacles To The Elimination Of Malaria From Peninsular Malaysia: Knowledge, Attitudes And Practices On Malaria Among Aboriginal And Rural Communities, Rohela Mahmud May 2010

Opportunities And Obstacles To The Elimination Of Malaria From Peninsular Malaysia: Knowledge, Attitudes And Practices On Malaria Among Aboriginal And Rural Communities, Rohela Mahmud

Rohela Mahmud

Background: Despite continuous efforts by the government and private sectors, malaria is still a public health problem in rural Peninsular Malaysia. This study investigated household knowledge, attitude and practices (KAP) regarding malaria in two malaria endemic communities, forest-aboriginal and rural communities, in the Lipis district of Pahang state, Malaysia. Methods: A descriptive cross-sectional study with a semi-structured questionnaire was carried out among 100 and 123 households from forest-aboriginal and rural areas, respectively. Results: Knowledge about malaria and its transmission is significantly higher among the rural participants than the aborigines (86.2% vs 76%, p < 0.01). However, use of medicinal plants and beliefs in witchcraft and sorcery in treating febrile diseases were significantly higher among the aboriginal population (p < 0.01). There were no significant differences between the two communities in terms of the knowledge about malaria symptoms, attitudes towards its severity and practices in preventive measures against malaria by using mosquito bed nets. However, the knowledge and practice of different preventive measures to combat malaria, such as insecticide and the elimination of breeding areas, was significantly higher among the rural population than the aborigines (p < 0.001). Conclusions: Both communities were aware of malaria as a disease, but knowledge, attitudes and practices were inadequate. Providing efficient health education to people residing in malaria endemic areas would improve their understanding about malaria prevention in order to bring about the elimination of malaria from the country.

Improved Plasma Stability And Sustained Release Profile Of Gemcitabine Via Polypeptide Conjugation, Kiew Lik Voon, Cheong Soon Keng, Khalifah Sidik May 2010

Improved Plasma Stability And Sustained Release Profile Of Gemcitabine Via Polypeptide Conjugation, Kiew Lik Voon, Cheong Soon Keng, Khalifah Sidik

Kiew Lik Voon

To enhance the stability of the anticancer drug gemcitabine (2'-deoxy-2',2'-difluorocytidine), it was conjugated to poly-L-glutamic acid (PG-H) via a carbodiimide reaction. The synthesised poly-L-glutamic acid-gemcitabine (PG-G) was purified and characterised by using SDS-PAGE to estimate its molecular weight, HPLC to determine its purity and degree of drug loading, and NMR to elucidate the structure. In vitro aqueous hydrolytic studies showed that the gemcitabine release from the polymeric drug conjugate was pH dependent, and that the conjugation to PG-H improved its stability in human plasma. The release of the bound gemcitabine from PG-G in plasma was mediated by a hydrolytic process. …


Basketball’S Forgotten Experiment: Don Barksdale And The Legacy Of The United States Olympic Basketball Team, Chad R. Carlson May 2010

Basketball’S Forgotten Experiment: Don Barksdale And The Legacy Of The United States Olympic Basketball Team, Chad R. Carlson

Chad Carlson

The 1948 United States Olympic basketball team has largely been fotgotten in the annals of American history despite taking a major step toward racial integration in American sports. Don Barksdale, the first African American to represent the US on the hardwood in the Olympics, joined nine players from the American South and legendary University of Kentucky coach, Adolph Rupp - a man notoriously identified as a racist. While Barksdale experienced very little racial mistreatment during the London Olympics, the lead-up to the Games reveals America's ambiguous views on race relations. During training in the segregated states of Oklahoma and Kentucky, …

Participatory Rural Appraisal, Ganesh Chandra Apr 2010

Participatory Rural Appraisal, Ganesh Chandra

Ganesh Chandra

Participation, empowerment and inclusion have become the new development buzzword. There has been a range of interpretations of the meaning of participation in development. Participatory development starts from the premise that it is important to identify and build upon strengths already present in communities. Perhaps the most widespread appearance of participation in mainstream development has been seen in the form of participatory methodologies of research, intended to gather a wide range of information from local people at their livelihoods, needs, and strengths, at the same time as 'empowering' them through a process of collaborative analysis and learning. PRA is a …


Dissemination Of Communication And Information In Inland Fisheries, Ganesh Chandra Apr 2010

Dissemination Of Communication And Information In Inland Fisheries, Ganesh Chandra

Ganesh Chandra

Flow of communication and information from the research station to the end user is sine qua non for the sustainable production as well as productivity enhancement in inland fisheries and the development of fishers as a whole. The resource poor who are often more in need than others of information on sustainable and low external input technologies is least likely to gain access to the information required. This has been seen particularly in the fisheries sector where the channels of information accessible to the resource poor delivered information on new practices and recommendations as well as the new culture technologies, …


Effects Of Fully Developed Vesicular Arbuscular Mycorrhizal Hyphae On Seed Germination Of Lolium Perenne, G Keith Bartley Jr, Richard J. Gualandi Jr, Robert M. Augé Apr 2010

Effects Of Fully Developed Vesicular Arbuscular Mycorrhizal Hyphae On Seed Germination Of Lolium Perenne, G Keith Bartley Jr, Richard J. Gualandi Jr, Robert M. Augé

Gregory Keith Bartley Jr.

Previous studies demonstrate that the inoculation of mycorrhizal spores in seeds can improve speed of germi- nation and establishment in grass seedlings. The universally positive effects of arbuscular mycorrhiza on plants suggest that fully developed mycorrhizal hyphae could potentially induce faster germination in seeds. This study presents data indicating that the inoculation of full grown hyphae in seeds of Lolium perenne inhibits speed of germination, independent of level of available soil nutrients. Daily measurements of seedling height between in- fected and non-infected plants at different starter fertilization rates in a sand profile showed that abuscular mycor- hiza influenced seeds emerged …

Vascular Plants Of Adjacent Serpentine And Granite Outcrops On The Deer Isles, Maine, U.S.A, Nathaniel Pope, Tanner B. Harris, Nishanta Rajakaruna

Nishanta Rajakaruna

We performed a comparative study of the vascular flora of a serpentine outcrop, Pine Hill, and that of a granite outcrop, Settlement Quarry, from Little Deer Isle and Deer Isle, respectively, Hancock County, Maine. We established four transects along a gradient from exposed to forested areas within each outcrop. Plants were recorded for presence and percent cover from circular plots along each transect. Soil and tissue samples were collected to examine soil-tissue elemental relations. One hundred thirty-two taxa were recorded from serpentine and 89 from granite. Fifty-seven taxa were shared by both sites. Species richness (α diversity) and diversity indices …

Comparison Of Nine Different Real-Time Pcr Chemistries For Qualitative And Quantitative Applications In Gmo Detection, Torstein Tengs Mar 2010

Comparison Of Nine Different Real-Time Pcr Chemistries For Qualitative And Quantitative Applications In Gmo Detection, Torstein Tengs

Dr. Torstein Tengs

Several techniques have been developed for detection and quantification of genetically modified organisms, but quantitative real-time PCR is by far the most popular approach. Among the most commonly used realtime PCR chemistries are TaqMan probes and SYBR green, but many other detection chemistries have also been developed. Because their performance has never been compared systematically, here we present an extensive evaluation of some promising chemistries: sequenceunspecific DNA labeling dyes (SYBR green), primer-based technologies (AmpliFluor, Plexor, Lux primers), and techniques involving double-labeled probes, comprising hybridization (molecular beacon) and hydrolysis (TaqMan, CPT, LNA, and MGB) probes, based on recently published experimental data. …


Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi Mar 2010

Metals: Typical And Less Typical, Transition And Inner Transition, Fathi Habashi

Fathi Habashi

While most chemists agree on what is a metal and what is a non-metal there is a disagreement with respect to what is a metalloid and what is a transition metal. It is believed that this problem can be solved if two new terms are adopted: typical and less typical metals. These new terms will also help reconcile the European Periodic Table versus the North American regarding numbering of groups as well as the IUPAC numbering which could be as well abandoned in favour of group names as will be shown in the manuscript.


The Future Of Southern Agriculture, Gregory Keith Bartley Jr. Mar 2010

The Future Of Southern Agriculture, Gregory Keith Bartley Jr.

Gregory Keith Bartley Jr.

The increasing demand for the supply of energy in the south heavily impacts the allocation of water for use in agriculture. With such a high percentage of the south's freshwater going towards energy production, little can make its way into food, feed, and fiber. Because the need for this exponential energy production in the south is currently greater than its agricultural importance, southern farmers are left to endure heavy irrigation restrictions. The solution to this problem can manifest itself in one of two ways. Southern states can either implement strategies that can reduce plant water consumption without reducing yield, or …

Acoustic Communication In The Asian Elephant, Elephas Maximus Maximus, Shermin De Silva Feb 2010

Acoustic Communication In The Asian Elephant, Elephas Maximus Maximus, Shermin De Silva

Shermin de Silva

Existing knowledge of acoustic communication in elephants is based primarily on African species (Loxodonta africana and Loxodonta cyclotis). There has been comparatively less study of communication in Asian elephants (Elephas maximus). In order to provide a basis for understanding the evolution and function of acoustic communication in proboscideans, I present a quantitative description of vocal communication in wild Asian elephants. I classify calls by acoustic features into 8 ‘single’ calls, 5 ‘combination’ calls and one possibly unique male call for a total of at least 14 distinct call types. Some of these vocalizations have never before been described. Certain low-frequency …

Evaluating The Illinois Stream Valley Segment Model As An Effective Management Tool, Stephen S. Warrner, Robert U. Fischer, Ann M. Holtrop, Leon C. Hinz Jr., James M. Novak

James M. Novak

Stream habitat assessments are conducted to evaluate biological potential, determine anthropogenic impacts, and guide restoration projects. Utilizing these procedures, managers must first select a representative stream reach, which is typically selected based on several criteria. To develop a consistent and unbiased procedure for choosing sampling locations, the Illinois Department of Natural Resources and the Illinois Natural History Survey have proposed a technique by which watersheds are divided into homogeneous stream segments called valley segments. Valley segments are determined by GIS parameters including surficial geology, predicted flow, slope, and drainage area. To date, no research has been conducted to determine if …

Henry R. Owen

Stylisma pickeringii var. pattersonii (Convolvulaceae) is endangered in Illinois and Iowa, and occurs in scattered populations in other states. During 1999 and 2000, two insect species previously unreported from Illinois were observed visiting its flowers. This study was undertaken to survey additional insect visitors, as well as to characterize the plant community where S. pickeringii occurs. The objectives were to survey: 1) floral traits (anthesis and flower density) of S. pickeringii, 2) associated plant species, and 3) insect visitor characteristics. Floral traits were determined and associated plant species surveyed in Mason County (degraded hay field on private property) and Henderson …

What Are Social Insects Telling Us About Aging?, Joel D. Parker

Joel D Parker

Abstract: Research on aging in social insects has progressed much more than has been generally acknowledged. Here I review what I think are the four greatest contributions of social insect work to the field of aging research with the hope of highlighting the truly exciting discoveries being made. These include the reversal of the fecundity / lifespan and size / lifespan trade-offs due to the evolution of sociality, that social environment can reverse the effects of aging, the contribution of social insect work to the overturning of the free radical theory of aging, and the discovery of vitellogenin as an …

Landowner Attitudes Toward Elk Management In The Pine Ridge Region Of North-Western Nebraska, R. Daniel Crank, Scott E. Hygnstrom, Scott R. Groepper Mr., Kit M. Hams

Scott R Groepper

Abstract: Little is known about attitudes of landowners toward elk (Cervus elaphus) on privately-owned land. We mailed questionnaires to agricultural landowners in the Pine Ridge region of northwestern Nebraska in both 1995 and 1997 to determine attitudes toward elk populations and management of elk. Fifty-six percent (n = 214) of respondents in 1995 and 57% (n = 461) in 1997 were in favor of free-ranging elk. Motivation for those in favor of elk was utilitarian (opportunity to view and hunt elk), ecological (return of a native species), and economic (benefi ts from increased tourism and leased land for elk hunting). …
