Balanites aegyptiaca (L) Del is a medicinal plant used in several folk medicines and as food condiment etc Africa [1]. Medicinal plants contain large varieties of chemical substances which possess important therapeutic properties that can be utilized in the treatment of human diseases [2]. There are several reports in the literature regarding the chemical components of extracts prepared from pl...

This study was carried out to relate the diversity of one crop in terms of number of landraces and farm area with the diversity of other crop. Information collected during baseline survey of in-situ global project (1999) on three crops namely rice, finger millet and sponge gourd in Jumla, Kaski and Bara of Nepal were used. Farm area of each variety and number of landraces grown by sampled house...

In the Sahelian zone of Ouaddaï in Chad, Balanites aegyptiaca (L.), Sclerocarya birrea (A. Rich.) and Ziziphus mauritiana Lam. are multipurpose woody species that found agroforestry land use systems contribute to nutrition, health economy local populations. The purpose study is assess natural regeneration population structure these view their domestication. was carried out ...

A culture of Saccharomyces cerevisiae M30 entrapped in loofa-reinforced alginate was used for continuous ethanol fermentation in a packed-bed reactor with initial sugar concentrations of 200-248 g/L. Maximum ethanol productivity of 11.5 g/(L·h) was obtained at an ethanol concentration of 57.4 g/L, an initial sugar concentration of 220 g/L and a dilution rate (D) of 0.2 h(-1). However, a maximum...

Willows (Salix: Salicaceae) form a major ecological component of Holarctic floras and consequently are an obvious target for a DNA-based identification system. We surveyed two to seven plastid genome regions (~3.8 kb; ~3% of the genome) from 71 Salix species across all five subgenera, to assess their performance as DNA barcode markers. Although Salix has a relatively high level of interspecific...

During the last decades, large-scale land use changes took place in the Hailiutu River catchment, a semiarid area in northwest China. These changes had significant impacts on the water resources in the area. Insights into groundwater and surface water interactions and vegetationwater dependencies help to understand these impacts and formulate sustainable water resources management policies. In ...

Despite growing concern and research interest in plant invasions, we know very little about ecological processes involved during invasion episodes. Understanding these dynamics is especially important for habitats subject to reestablishment of historical disturbance regimes; because many invasive species respond positively to disturbance, interactions between colonizing natives and nonnatives a...

In this paper, we give a completely elementary proof of Ramanujan’s circular summation formula of theta functions and its generalizations given by S. H. Chan and Z. -G. Liu, who used the theory of elliptic functions. In contrast to all other proofs, our proofs are elementary. An application of this summation formula is given.
