Research ArticleOpen accessIn the abstractObserved Abrupt Changes in Minimum and Maximum Temperatures in Jordan in the 20th CenturyMahmoud M. SmadiThis study examines changes in annual and seasonal mean (minimum and maximum) temperatures variations in Jordan during the 20th century. The analyses focus on the time series records at the Amman Airport Meteorological (AAM) station. The occurrence of abrupt changes and trends were examined using cumulative sum charts (CUSUM) and bootstrapping and the Mann-Kendall rank test. Statistically significant abrupt changes … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 7,925 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBoosted Regression Estimates of Spatial Data: Pointwise InferenceMarco Di Marzio, Charles C. TaylorIn this study simple nonparametric techniques have been adopted to estimate the trend surface of the Swiss rainfall data. In particular we employed the Nadaraya-Watson smoother and in addition, an adapted-by boosting-version of it. Additionally, we have explored the use of the Nadaraya-Watson estimator for the construction of pointwise confidence intervals. Overall, boosting does seem to improve the estimate as … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,349 accessesView PDF Cite

Research ArticleOpen accessIn the abstractApplication of Geo-Information Technology in the Study of Soil and Nutrients Loss by Water Erosion for three Different Land CoverMushtak T. Jabbar, C. A.I. Chong-Fa, Wang Tian-Wei, Shi Zhi-HuaThis research integrated the Revised Universal Soil Loss Equation (RUSLE) and the soil statistical analysis with RS and GIS techniques to quantify soil and nutrient loss risk. The Letianxi watershed, located in the southwest part of Hubei Province of China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,790 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSoil Degradation Risk Prediction Integrating RUSLE with Geo-information Techniques, the Case of Northern Shaanxi Province in ChinaMushtak T. Jabbar, Xiaoling ChenThis research integrated the Revised Universal Soil Loss Equation (RUSLE) with RS, GIS and GPS techniques to quantify soil erosion risk and the northern part of Shaanxi province in China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. The rating values served as inputs into a modified Revised … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,050 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Root Rot in Soybean Cultivars with Diverse Susceptibility to the Disease on Plant Physiology, Yield, Amino Acids and Mycotoxins Profile in Climatic Conditions of KazakhstanNurlan Kuldybayev, Yerlan Dutbayev, Bozena Lozowicka et al.Soybean is an important high-value crop but susceptible to soil-borne diseases. A field trial was conducted in Kazakhstan to evaluate the effects of soybean cultivars and Fusarium root rot severity on soybean crop physiology, chlorophyll fractions and amino acids profile. The highest yield was achieved in 2018 (up to 4 t ha-1) for K-9648 cultivar. The greatest root rot severity … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 27 Dec 2021 · 6,299 accessesView PDF Cite
