Cassia sieberiana D.C. (Fabaceae) though widely used in traditional medicine as an analgesic in dysmenorrhoea, ulcer and general body pains; there is no published report on it standardization. Pharmacognostic evaluation of the root will therefore assist in standardization for quality, purity and sample identification of the plant drug. Evaluation of fresh and powdered root of this plant was car...

The Dongpan section in southern Guangxi Province records the influence of local volcanic activity on marine sedimentation at intermediate water depths (~200-500 m) in the Nanpanjiang Basin (South China) during the late Permian crisis. We analyzed ~100 samples over a 12-m-thick interval, generating palynological, paleobiological, and geochemical datasets to investigate the nature and causes of e...

The aim of the study was to determine if an As-contaminated soil, stabilized using zerovalent iron (Fe(0)) and its combination with gypsum waste, coal fly ash, peat, or sewage sludge, could be used as a construction material at the top layer of the landfill cover. A reproduction of 2 m thick protection/vegetation layer of a landfill cover using a column setup was used to determine the ability o...

Emerald ash borer (Agrilus planipennis Fairmaire) is an invasive primary pest of North American ash (Fraxinus spp.) trees. Blue ash (F. quadrangulata) is less susceptible to emerald ash borer infestations in the forest than other species of North American ash. Whereas other studies have examined adult host preferences, we compared the capacity of emerald ash borer larvae reared from emerald ash...

To improve basic knowledge of the properties of soybean straw, its fiber properties, anatomical structure, and components were investigated in detail. Soybean straw contains less ash and silica than some non-woody biomass. Its stem and root have more lignin and holocellulose, but less nitrogen and protein contents than the pod. Additionally, it has much shorter and wider fibers, and the length-...

In our contribution we present the fabrication of Si1−xGex alloy by ion-implantation and millisecond ash lamp annealing. The 100 keV Ge ions at the uence of 10 × 10, 5 × 10, and 3 × 10 cm−2 were implanted into monocrystalline (100)-oriented Si wafers covered by 50 nm thermal oxide. In the consequence, the 50 nm amorphous Ge rich Si layers were obtained. The recrystallization of the implanted la...

Root extracts of Withania somnifera (Ashwagandha) are commonly used as a remedy for a variety of ailments and a general tonic for overall health and longevity in the Indian traditional medicine system, Ayurveda. We undertook a study to investigate the anti-proliferative and differentiation-inducing activities in the water extract of Ashwagandha leaves (ASH-WEX) by examining in glioma cells. Pre...

Imperata cylindrica Linn. Beauv (Poaceae), commonly known as Darbh in Hindi, is an important drug of “Trinpanchmool” and used extensively for the treatment of various ailments viz. urinary calculi, retention of urine, diabetes, cardiac disorder, gout, common cough and cold, inflammation, anemia, as aphrodisiac, etc. The present study was aimed to undertake pharmacognostical studies to fulfill t...

Leaching of fluoride from fly ash has been studied at different ash/water ratios and temperatures and also over a broad range of pH. The efficiency of leaching was only slightly dependent on the ash/water ratio, thus revealing a solubilitycontrolled mechanism of the process. The efficiency was also independent of the temperature over the range 20 90°C.

Most applications of coal fly ash, such as concrete, structural fill, and waste stabilization, use fresh fly ash received directly from coal fired power generation plants. However, if the current rate of usage continues, the demand for fresh coal fly ash for various applications will increase and utilization of coal fly ash disposed in landfills will have to be considered. This study investigat...
