background : proteus spp. belongs to the family of enterobacteriaceae . these bacteria are gram-negative and motile microorganisms and known as the third most common causes of urinary tract infections. the aim of the current study was to investigate the effects of some secondary metabolites from probiotic strains of lactobacillus spp. on swarming and growth of proteus mirabilis and p. vulgar...
to study the impact of growth factor bacteria , humic acid and alga extract in drought stress condition a test is established in form of completely random blocks and spilt plot in 4 replications in a field in mahallat in arak province in 1389. two primary plots including irrigation and stress and secondary plots including growth factor bacteria ,humic acid and alga extract, ascophylu...
Fungi produce a wide range of secondary metabolites such as antibiotics, toxins, alkaloids, fatty acids, ketones and alcohols during active cell growth. The present study was aimed to identify secondary metabolites from some Penicillium species, using GC-MS. Many important compounds such as 3-oxoquinuclidine in Penicillium jenseii, formamidine in Penicillium pusillum, orcinol and 1,3,8-p-mentha...
Higher plant vasculature is characterized by two distinct developmental phases. Initially, a well-defined radial primary pattern is established. In eudicots, this is followed by secondary growth, which involves development of the cambium and is required for efficient water and nutrient transport and wood formation. Regulation of secondary growth involves several phytohormones, and cytokinins ha...
Introduction: The earthquake is a natural disaster that has many psychological effects on the survivors and nurses that are associated with them. The purpose of this study was to predict secondary traumatic stress and post-traumatic growth based on cognitive emotion regulation in nurses providing services to earthquake victims in Kermanshah. Methods: The present study is a descriptive-correlat...
the effects of plant densities (25, 35 and 45 plants m-2 as d1, d2 and d3 respectively), and inoculation with rhizobium bacteria (without rhizobium, with rhizobium and rhizobium + microelement application), on growth and yield were studied in chickpea (cicer arietinum l.). experiment was carried out in 2008 at research farm of the faculty of agriculture of university of mohaghegh ardabil, a fac...
Physical laws and processes have profoundly influenced plant evolution. Their effects are invariably size dependent and thus subject to scaling as well as biophysical analyses even though these effects differ depending upon the fluid (water or air) in which plants evolve. Although organisms cannot obviate the effects of physical laws and processes, the consequences of these effects can be alter...
