Micro-topography has been proved to be beneficial for plant colonization in severe environments. There are numerous micro-topographies caused by erosion of gangue dumps the Northeast China, which can make difficult. To determine how these affect colonization, environment conditions, regeneration characteristics, vegetation characteristics different micro-topographies, such as bare slope, rill, ...

Limited information is currently available on how sediment transport affects rill flow resistance and the influence of hydraulic variables, as stream power, capacity for flows. In this paper, measurements variables (flow depth, channel slope, mean velocity, Reynolds number, Froude Darcy–Weisbach friction factor) carried out by Ban et al. (Measurement ephemeral gully velocities their model expre...

N,N'-dinitrosopiperazine (DNP) with organ specificity for nasopharyngeal epithelium, is involved in nasopharyngeal carcinoma (NPC) metastasis, though its mechanism is unclear. To reveal the pathogenesis of DNP-induced metastasis, immunoprecipitation was used to identify DNP-mediated phosphoproteins. DNP-mediated NPC cell line (6-10B) motility and invasion was confirmed. Twenty-six phosphoprotei...

Amikacin sulphate is devoid of any chromophore and/or conjugated system prerequisite for UV and florescent light detection (FLD). Hence, there is a need of simple and reliable methods for introducing chromophore in the structure of amikacin sulphate for its determination using UV and FLD. Therefore, the present study describes the development and validation of a simple, economical and fast colo...

Previous studies have shown that the development of mam mary alveolar lesions (MALs) precedes the emergence of overt mammary tumors in high-breast-cancer strains of mice, such as Rill, that are infected with exogenous murine mammary tumor virus. We cultured MAL-containing whole mammary glands from 7-month-old nulliparous Rill mice for 8 days (Days 0 to 8) in a serum-free medium that contained i...

Some methodologies were compared in providing erosion maps of surface, rill and gully and erosion features, in research which took place in the Varamin sub-basin, north-east Tehran, Iran. A photomorphic unit map was produced from processed satellite images, and four other maps were prepared by the integration of different data layers, including slope, plant cover, geology, land use, rocks erodi...

Agroforestry is a dynamic, ecologically based, natural resource management system that, through the integration of trees in farm and rangeland, diversifies and sustains production for increased social, economic and environmental benefits (Leakey, 1996). Apart from the social and cultural advantages of growing trees, recreational benefits for human being, as well as improvement in wildlife, ther...
