Thermo-chemical sequestration of naphthalene using Borassus flabellifer Shell activated carbon: Effect of influencing parameters, isotherm and kinetic study

The present research describes the removal of naphthalene from aqueous solution using one of the simplest agricultural wastes, Borassus flabellifer Shell activated carbon (BFS-AC) by adsorption. Adsorption was chosen due to its cost-effectiveness. The effect of operating parameters such as pH, time, initial concentration of naphthalene, BFS-AC dosage and temperature on the percent removal of naphthalene was determined....

Evaluation of insulin-like growth factor-I gene polymorphism in Egyptian small ruminant breeds

The genetic improvement of production traits can be developed through marker assisted selection. Insulin-like growth factor I (IGF-I) is a member of the somatotrophic axis which has a remarkable variation of its biological effect including protein synthesis and skeletal growth. This study aimed to detect the genetic polymorphism of IGF-1 in different Egyptian sheep and goat breeds. The amplified fragments at 320-bp were...

Effect of organic matter, irrigation and soil mulching on the nutritional status and productivity of okra (Abelmoschus esculentus L.) in the semiarid region of Brazil

Okra (Abelmoschus esculentus L) is an important vegetable crop currently cultivated in many parts of the world. The adoption of management strategies to promote the nutritional status and crop productivity in semiarid regions of Brazil is still poorly studied. Thus, this experiment was conducted to evaluate the effect of raising the level of organic matter in the soil, irrigation and soil mulching in the nutritional...

Growth promotion mediated by endophytic fungi in cloned seedlings of Eucalyptus grandis x Eucalyptus urophylla hybrids

Eucalyptus cultivation has expanded considerably in Brazilian systems, leading to the current search for technologies to optimize growing conditions and the production of seedlings in nurseries. Based on the understanding that the development of tree species such as Eucalyptus sp. can be influenced by endophytic fungi that act directly as plant growth-promoting species, cloned seedlings of Eucalyptus grandis x...

Primary study on the components and main physico-chemical as well as biological properties of the oil of Alpinia galanga (L.) Wild in Phu Tho-Vietnam

The oil of Alpinia galanga (L.) Willd in Phu Tho was obtained by steam distillation and dried with Na2SO4. By Gas chromatography-mass spectrometry (GC-MS) method, 29 components in the oil were predicted by comparing their retention times and molecular weights with the standards’. In particular, there were 10 hydrocarbons such as monoterpenes: 29.15%, sesquiterpenes: 21.06%, and 19 oxygenated components like...
