Research ArticleOpen accessEvery word in the titleAntagonistic Effects of Fertilizer on Photochemical Efficiency of Hibiscus cannabinus L. (Kenaf) Planted on Beach Ridges Interspersed with Swales SoilMohd-Hazimy Yusoff, Hazandy Abdul-Hamid, Arifin Abdu et al.Problem statement: Hibiscus cannabinus L. or Kenaf is a highly productive, warmseasonal C3 annual crop and is one of the potential candidates to substitute kenaf fiber as raw product for pulp and paper production. It survives well on less fertile soils including those of Beach Ridges Interspersed with Swales (BRIS) soil. Approach: The objective of this study was to determine … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 19 Sep 2011 · 8,511 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleReview of Photochemical Smog Pollution in Jakarta Metropolitan, IndonesiaDollaris R. Suhadi, M. Awang, M. N. Hassan et al.An analysis of photochemical smog pollution in Jakarta was attempted using data from the existing air quality monitoring stations. Ground-level ozone potential is high in Jakarta due to the high traffic emissions of ozone precursors and the favorable surface meteorological conditions. Despite the frequent missing data during the 1996-1999 monitoring, which resulted in lower ozone values, ozone episodes were significantly … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,247 accessesView PDFCite
Review ArticleOpen accessIn the keywordsHerbal Compounds-An Alternative for Multi-Drug Resistant Vibrio CholeraeSabah Perveen, Hotam Singh ChaudharyVibrio cholerae is a causative agent of cholerae, many people dies every year, especially in developing countries around the world. The outbreaks of cholera are responsible for approximately 120,000 deaths annually. Cholera is a self limiting illness; however antibiotics are used as a part of treatment regimen. But at present, the treatment against cholera has become very critical issue worldwide, … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 12 Oct 2015 · 7,260 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLeaf Chlorophyll Fluorescence and Gas Exchange Response to Different Light Levels in Platycerium bifurcatumRuzana-Adibah Mohd Sanusi, Ainuddin Ahmad Nuruddin, Hazandy Abdul HamidProblem Statement: Platycerium bifurcatum (Cav.) C. Chr. is epiphytes which lives in forest canopy and commonly used for its ornamental value. In these environments, they were always exposed to many types of stresses such as high light intensity. Light intensity plays an important role in affecting plant’s physiological performance. Therefore, the purpose of this study was to investigate physiological responses … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,981 accessesView PDFCite
Research ArticleOpen accessIn the keywordsVariation of Surface Ozone Recorded at the Eastern Coastal Region of the Malaysian PeninsulaAida Shafawati Ismail, Mohd Talib Latif, Siti Zawiyah Azmi et al.Problem statement: Variations of ozone (O3) concentrations in the Eastern Coastal Region of the Malaysia peninsula were investigated using data obtained from the Malaysian Department of the Environment. The aim of this study was to determine the monthly and seasonal variations of ozone concentrations at all monitoring sites. This study deals with the air quality data recorded at four air … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 8,072 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Effects and Phytotoxicity of Photo Fenton Solutions and Acid Rains on Cucumber (Cucumis Sativus) Plants: Treats and ConsoleFawzy Eissa, Sayuri Bandai, Nour El-Hoda Zidan et al.The Eco-physiological assessments of variable parameters known to be essential for proper plant growth and health were determined in cucumber plants exposed to short term treatments in 42 days using two broad classification types; Photo Fenton solution generating OH radicals and simulated acids. Solutions containing different classification of scavengers of OH radicals and mannitol were employed as Controls. Results indicated … …American Journal of Environmental Sciences, Vol. 16, Issue 2 · 21 May 2020 · 6,974 accessesView PDFCite
Review ArticleOpen accessIn the abstractNASA Sees First in 2018 the Direct Proof of Ozone Hole RecoveryRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuFor the first time, scientists have shown through direct observations of the ozone hole by a satellite instrument, built by NASA's Jet Propulsion Laboratory in Pasadena, California, that levels of ozone-destroying chlorine are declining, resulting in less ozone depletion. Measurements show that the decline in chlorine, resulting from an international ban on chlorine-containing human-produced chemicals called Chlorofluorocarbons (CFCs), has resulted … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 22 Jan 2018 · 10,688 accessesView PDFCite
Research ArticleOpen accessIn the abstractFar-Red Spectrum of Second Emerson Effect: A Study Using Dual-Wavelength Pulse Amplitude Modulation FluorometryV. S. Lysenko, T. V. Varduny, E. I. Simonovich et al.Non-additive enhancement of the photosynthesis excited by simultaneous illumination with far-red light and light of shorter wavelengths is called as "second Emerson effect". Its action spectra are well-known as a photosynthetic yield's dependence on light wavelength in red (630-690 nm) spectral region at a constant-wavelength far-red illumination near 700-715 nm. However, the opposite dependence of the photosynthetic yield's of shorter … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 19 Nov 2014 · 7,957 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Transport Phenomena on Pollutants Concentration in Mediterranean Tunisian RegionsKarim Bouchlaghem, Blaise Nsom, Jean-Francois DorvilleThe objective of this study is to investigate the origin of the polluted air masses in the Tunisian Mediterranean regions and to characterize the atmospheric conditions and the transport and dispersion mechanisms that give rise to pollution events. For this end, we conducted continuous measurements campaigns of surface ozone concentration and meteorological parameters during summer 2011 using mobile and fixed … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 23 Jan 2014 · 6,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractIN-SEASON ASSESSMENT OF WHEAT CROP HEALTH USING VEGETATION INDICES BASED ON GROUND MEASURED HYPER SPECTRAL DATAKhalid Ali Al-Gaadi, Virupakshagouda Patil, ElKamil Tola et al.An experiment on a 50 ha center pivot field was conducted to determine the Vegetation Indices (VI’s) that were helpful in assessing the in-season performance of wheat crop treated with graded levels of irrigation water and fertilizers. The irrigation levels were at 100, 90, 80 and 70% evapotranspiration (ETc); however, the fertilizer levels of N: P: K kg-1ha included 300:150:200 … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 7 Jan 2014 · 7,518 accessesView PDFCite
