To determine the effects of kimchi extracts at different temperatures on larval development, Ascaris suum eggs were mixed with soluble part of 7 different brands of commercially available kimchi and preserved at either 5℃ or 25℃ for up to 60 days. A. suum eggs incubated at 25℃ showed marked differences in larval development between kimchi extract and control group. While all eggs in the control...
The numerous apparent malformations of eggs from laying breeder flocks are affected by the increased age of the flocks. The bulking and spinning of eggs causes them to be placed in small end up (SEU) condition in the incubation period and eventually inoculation of the virus is done incorrectly. Present study was designed to investigate the effect of egg condition on embryos deaths, amnio-allant...
to evaluate the effects of different dry period lengths on milk yield, milk composition, reproductive performance and energy balance in dairy cows, 30 holstein breeds (average 270 days pregnant) were made use of in a randomized complete block design. cows were assigned to three treatments (60, 45 and 30 days of dry period) and two blocks as based on parity (either first lactation or multifariou...
Solid-state fermentation was carried out using mycelium powder of Aspergillus niger as substrate for the production chitosanase Streptomyces. Results experiments indicated that optimal medium consisted wheat bran and with initial moisture content 60% - 70%. The enzyme activity reached 41.33 U per gram dry after cultured 5 days at 28°C 30°C an pH 6.5. Chitosanase detected on second day i...
this study was an attempt to investigate the effect of using c-test passages on the reading comprehension and incidental vocabulary learning of iranian intermediate efl learners. the participants were 60 male efl learners at kish mehr institute in garmsar. in fact, there were two groups, an experimental group and a comparison group with 30 students in each. the participants were pretested throu...
it is known that native oil-degrading microorganisms are ubiquitous. they can be isolated from contaminated soils. in this study, biodegradation experiments were carried out to evaluate the efficiency of pollutant removal by adding the selected microorganisms. five mixed cultures and 3 single bacteria strains, pseudomonas sp., arthrobacter sp. and mycobacterium sp. were isolated from hydrocarbo...
Soil carbon (C) mineralization was studied in an incubation experiment comprised of two factors having six organic materials and three nitrogen (N) rates. Cow dung (CD), rice straw (RS), wood ash (WA), cow biochar (CB), (RB) (WB) considering 2.5 g C kg?1 soil along with levels N, i.e., 0, 0.05 0.10 N were mixed 400 used each pot. The pots placed for 30, 60, 90, 120, 150 180 days incubation, soi...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Materials and methods: A total of 68 molar bands were tried-in mouth of 17 patients. After try-in, 60 bands were cleaned in ultrasonic cleaning bath and then were equally divided into two groups (n = 30). Bands from group 1 were autoclaved in benchtop autoclave. Bands from group 2 were sterilized in glass bead sterilizer. After sterilization, the bands from both the groups were incubated in 50 ...
