Research ArticleOpen accessIn the abstractHost Plant Mediated Population Variations of Cotton Whitefly Bemisia tabaci Gennadius (Aleyrodidae: Homoptera) Characterized with Random DNA MarkersYasodha Perumal, Murugan Marimuthu, Abida Puthenpeedikal Salim, Balasubramanian PonnusamyProblem statement: Whitefly, Bemisia tabaci is an important sucking pest of field, horticultural and ornamental plants causing feeding injuries besides spreading disease by acting as a vector of Gemini viruses. The polyphagous nature of the pest makes it as a highly complex species. Approach: The influence of host plants utilized by the species on the population differences at molecular level … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,215 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of Benthic Fauna in the Discharge Lagoon of a Shrimp Farm With Special Emphasis on the PolychaetesLuis Rafael Martínez Córdova, Luis Fernando Enríquez OcañaA study of benthic fauna, with special emphasis on polychaetes, was made in the discharge lagoon of an experimental shrimp farm and a pond of the farm. The discharge lagoon was divided into three sections and stocked with shrimp at low density (6 Pl/m2). Neither formulated feed nor fertilization was used in these sections. The control pond was stocked with … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 6,684 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Variability of Indonesian Throughflow in Sumba Strait and Its Linkage to the Climate EventsAhmad Bayhaqi, Yueng-Djern Lenn, Dewi Surinati et al.As one of the Indonesian Throughflow (ITF) outflow passages, the Sumba Strait is a meeting point for the Pacific and the Indian Ocean water mass. In order to study the long-term variability of ITF flowing via Sumba Strait, this research uses observational data from the Ekspedisi WIdya Nusantara (EWIN) research cruise conducted in August 2016 to validate the altimetric geostrophic … …American Journal of Applied Sciences, Vol. 16, Issue 4 · 12 Jun 2019 · 8,830 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Soil Loss Using GIS and RUSLE Model in Bakiya River Basin (BRB), Central NepalSujan Bista, Naresh Kazi Tamrakar, Kishor Rimal, Arju BhattaraiSoil erosion is the major geological hazard in the fragile landscape of Sub-Himalaya. This study examines the susceptibility of the Bakiya River Basin (BRB) in Central Nepal to soil erosion because of its steep topography, fragile geology, the impact of intense monsoon rainfall, and the lack of a direct monitoring mechanism available for rainfall-runoff. This study examines the spatial variations … …Current Research in Geoscience, Vol. 14, Issue 1 · 20 Oct 2025 · 3,389 accessesView PDFCite
Research ArticleOpen accessIn the abstractCFD Simulation of Biogas Fired Clay Brick KilnAlemayehu Beyene, Venkata Ramayya, Getachew ShunkiMore strong and quality clay bricks are obtained if and only if bricks are fired with uniform optimum temperature during clay brick firing process in the clay brick kiln. To insure this transient temperature of fluegas and brick are analyzed using CFD simulation during clay brick firing in the clay brick kiln. In the simulation, 3-D geometrical model of fluegas … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 20 Jun 2018 · 8,807 accessesView PDFCite
Research ArticleOpen accessIn the abstractUrbanization Effect on Air Temperature in Iran's Zayanderud River BasinAli Zahraei, Sara Saadati, Saeid Eslamian et al.: Detection of urbanization effect to understand climate change is important. Urbanization effect on air temperature in Zayanderud river basin was evaluated using weather stations network. Map of the temperature trend was generated using full dataset and rural stations to visualize warming trends. A comparative analysis was carried out to estimate urban heat island effect. The result indicated that overall … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 11 May 2018 · 8,487 accessesView PDFCite
