Pollen viability and its germination capability for fruit set in are almond and peach essential. To optimize the pollen culture medium of almond and peach and selection of best medium, the present study was carried out with 48 different culture media containing different compositions including diverse levels of boric acid (0 and 100mg/1), calcium nitrate (0,150and300mg/l،), magnesium sulphate (...
BACKGROUND Bacterial vaginosis is associated with increased transmission of sexually transmitted infections, preterm labor, post-surgical infections, and endometritis. Current treatment for symptomatic bacterial vaginosis includes antibiotics, such as metronidazole, which are 70-80 % effective at one month after treatment and result in high recurrence rates and secondary candida infections. Int...
the major aim of this study was to investigate the relationship between iq, eq and test format in the light of test fairness considerations. this study took this relationship into account to see if people with different eq and iq performed differently on different test formats. to this end, 90 advanced learners of english form college of ferdowsi university of mashhad were chosen. they were ask...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Boron is an important micronutrient for plants, but high B levels in soils are often responsible for toxicity effects in plants. It is therefore important to understand reactions that may affect B availability in soils. In this study, Attenuated Total Reflectance Fourier transform Infrared (ATR-FTIR) spectroscopy was employed to investigate mechanisms of boric acid (B(OH)3) and borate (B(OH)4 )...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...

The objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘Camarosa’ strawberry (Fragaria × ananassa Duch.). The strawberry plants were sprayed with Boric acid at 0 (control), 50 and 100 mg L-1 at 30 days after planting. In general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...
this study is concerned with the viability of producing biodiesel from waste beef bone fat and evaluate this product according to the quality requirements defined by astm d- 6751. accordingly, beef bone fat was heated to remove the moisture under vacuum at 60 . alkaline catalysed transesterfication was carried out by using 6:1 molar ratio of ethanol to fat in the presence of 1% w/w sodium hydr...
Title of dissertation: THE EFFECT OF BORIC ACID ON THE GROWTH MECHANISM OF ELECTRODEPOSITED METAL NANOSTRUCTURES Lauren M. Graham, Doctor of Philosophy, 2014 Dissertation directed by: Prof. Sang Bok Lee Department of Chemistry & Biochemistry Electrochemical deposition (ECD) has been a primary method of metal plating for a variety of applications for nearly 100 years. Its popularity is due to it...
