In connection with the increasing demand in high-quality raw materials for brandy production, research intended to solve problems of industry associated using low-acid or low-sugar grapes is relevant. A promising direction improving quality outputs use yeasts desired properties and yeast metabolism products. The aim was study effect biotechnological agents on physicochemical composition base wi...

road construction is one of the effective factors for ecological changes which affects diversity and species composition in forest roads edges. this research was performed in kheirud forest to evaluate herbaceous diversity and tree regeneration establishment in different distances from road edge. for this purpose, we sampled herbaceous and tree species regeneration in 0,5,10,25, 50 and 100 m di...

The term “Precision Forestry” is being used more frequently in the forest products industry. This paper defines two broad categories of precision forestry as 1) using geospatial information in forest management and planning, and 2) site-specific silvicultural operations. One case study is presented for site-specific application of herbicides and fertilizers in herbaceous weed control activities...

Four categories of plant food dominated the diet of chimpanzees in Kibale Forest, Uganda: non-fig tree fruits, fig tree fruits, herbaceous piths and terrestrial leaves. Fruit abundance varied unpredictably, more among non-figs than figs. Pith intake was correlated negatively with fruit abundance and positively with rainfall, whereas leaf intake was not influenced by fruit abundance. Piths typic...

The detailed characterisation of middle distillates is essential for a better understanding of reactions involved in refining process. Owing to higher resolution power and enhanced sensitivity, comprehensive two-dimensional gas chromatography (GC x GC) is a powerful tool for improving characterisation of petroleum samples. The aim of this paper is to compare GC x GC and various ASTM methods -- ...

Through 1 I growing seasons, growth of Ioblolly pine (Pinus taeda L.) increased after control of herbaceous, woody, or both herbaceous and woody vegetation (total control)for thefirst 3 yr after planting on a bedded site in the Georgia coastal flatwoods. Gains in stand volume index from controlling either herbaceous or woody vegetatkn alone were approximately two-thirds that from controlling bo...

A common study design has been used at 13 locat ions across the South to examine loblol ly pine (Pinus taeda L.) plantations established using four vegetation control treatments after mechanical site preparat ion: (a) No Control , (b) Woody Control , (c) Herbaceous Control for 4 yr , and (d) Total Control . This research, the Compet i t ion Omission Moni toring Project (COMP), is moni toring bo...
