Case ReportOpen accessEvery word in the titleAbrus Precatorius Induced Hemorrhagic ColitisRajeshkumar Ganesan, Rajalakshmi EttiyanAbrus Precatorius commonly known as Rosary bead or Kundumani (Arena, 1986) is an irritant poison affecting almost all major systems of the body with more damage to the gastrointestinal system. The mortality rate is 10 to 15% for a lethal dose of just 1-2 crushed seeds. Following is the case report of hemorrhagic colitis due to the ingestion of a … …American Journal of Pharmacology and Toxicology, Vol. 10, Issue 2 · 13 Sep 2015 · 7,843 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePreparation and Polishing Properties of Spherical Porous Silica AbrasiveHong Lei, Hu Li, Ping Liu, Ruling ChenProblem statement: Abrasive is one of key influencing factors on the polished surface quality in Chemical Mechanical Polishing (CMP). Solid abrasives in CMP slurries are easy to cause polishing scratches. It is well known that reducing the hardness of abrasives would improve the polished surface quality. Therefore, the change in structure or shape of the abrasives means a change in … …Current Research in Nanotechnology, Vol. 1, Issue 1 · 15 Jun 2011 · 9,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleObserved 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 PDFCite
