introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
evaluation growth analysis and grain yield of sunflower cultivars under sowing date in dry condition
sunflower is one of the most important edible oil that growth of annual crops, it is grown over a widely area and is considered a crop adapted to an every environmental conditions, in order to study growth analysis of sunflower under sowing date and cultivars in dry condition a farm experiment was conducted a split plot arranged in a complete randomized block design with three replications in t...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
during the past decade, the world economic forum has published its annual reports in which the global competitiveness index is included. this paper aims to investigate the key factors for achieving an innovation-driven economy. in this paper, we used partial canonical correlation analysis (pcca) to examine the relationships between key pillars in “efficiency enhancers” and “business sophisticat...
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
the need for more comparisons among models is widely recognized. this study aimed to compare three different modelling approaches for their capability to simulate and predict trends and patterns of winter wheat yield in western germany. the three modelling approaches included an empirical model, a process-based model (lintul2), and a metamodel derived from the process-based model. the models ou...
in this study, the cdna growth hormone (cgh) of the belugasturgeon (husohuso) and russian sturgeon (acipensergueldenstaedtii) were cloned and sequenced, and phylogenetic relationships were examined using nucleic acid and amino acid sequences. the nucleotide sequence of the beluga gh has an open reading frame of 645 nucleotides encoding a protein 214 amino acid residues. the signal peptide cleav...
Bangladesh is still a low urbanized country although it experienced a rising trend in the level of urbanization throughout the twentieth century and had a remarkably high urban growth immediately after its independence in 1971. The country recorded the highest ever annual average growth rate (9.04) and percentage of interval variation (137.57%) in an urban population in 1974; thereafter, growth...
abstract in order to determine the time of maximum demand of winter wheat (triticum aestivum l.) to phosphorous fertilizers and p and zinc (zn) distribution in different parts of wheat at various growth stages and study their relation to the contents of these elements in soil p and zn under field conditions, samples were collected from different parts of the plants at seven growth stages (i.e.,...
