Efficacy of three biological control agents on black mold caused by Aspergillus niger fungus and growth and yield components of grapevines (Vitis vinifera L.) under field conditions
No full text The objectives of this study were to evaluate the efficacy of three biological agents (Pseudomonas fluorescens, Bacillus subtilis, and Trichoderma harzianum) to control black mold disease caused by Aspergillus niger on grapevines, and measuring their effects on growth and production parameters of this crop under field conditions. A foliar spray application was used to inoculate the plants with the A. niger spore suspension. The three bio-control agents were incorporated into the infected grapevine plants soil. Results showed that infection severity has reached in all treatments of biological agents to 0.00% compared to 11.14% in the negative control and 46.13% in positive control (infected untreated plants). Treatment of T. harzianum gave the highest values of growth and yield parameters which were significantly different from all other treatments. The interaction between P. fluorescens, T. harzianum and B. subtilis was the most effective treatment among other interactions, in reducing infection severity and increasing all the growth and yield parameters
Reducing The Microbialled Of Chicken Meat by Improving Grill Machine Design
No full textThe experiment was conducted to improve the microbial load and sensory characteristics of chicken meat using locally designed and manufactured an improved grill and compared it with traditional grill in the department of Agricultural Machines and Equipment/College of Agriculture, University of Baghdad in 2017. The study included test of complete roasted chicken samples that ready for sale consumption from the top and bottom rows of improved grill, also included incomplete roasted chicken samples from the top row in addition to complete roasted chicken that ready for sale and consumption from the bottom row of the traditional grill, as well as a control sample that was roasted chicken by putting it in traditional grill alone. Bacteriological included total number of aerobic bacteria (Aerobic Plate Count APC), total number Coliform, fecal E. coli, Staphylococcus aureus and Salmonella Spp, In addition to Molds and Yeasts were tested in this study. Despite the lack of microbial limits for roasted chicken in Iraqi standard specifications, the results showed that absence of all study samples, including control from the presence of Salmonella, but it showed the superiority of improved grill to reduce the mean of APC, coliform, yeasts and molds, which they are free of fecal coliform and Staphylococcus aureus, and recorded significant reducing. Also, high microbial load in complete roasted chicken samples that taken from the bottom row from traditional grill compared with improved grill demonstrates that the exudates fluids from the top row chicken on the bottom row chicken of the traditional grill has contributed to the rise of these microbial load, also demonstrates the erroneous practice adopted in the roasted method of chicken in the traditional grill, when the worker puts the chicken intended for roasting in the top rows of the grill and put the complete roasted chicken that ready for sale or consumption in the bottom of the grill, which contributes in contamination by exudates fluids that fall out of the raw and incomplete roasted chicken in the top row. The results of the current study also showed superiority of the improved grill to register the highest average in sensory evaluation scores of complete grilled chicken by the evaluators experts in a number of sensory qualities of odor, flavor, palatability and juiciness, it recorded significant differences compared with traditional grill, as well as it hood to get to complete roasting compared with samples of traditional grill and control.
Effects of Chemical and Physical Properties of Pond Bottom Sediments on Fish Rearing in Iraqi Kurdistan Region
No full text Some chemical and physical properties in soil- water interface in ponds of fish rearing in Duhok city Iraqi-Kurdistan region in summer 2014 such as (redox potential, exchange acidity, total and active calcium carbonate, soil pH and salinity, cation exchange capacity, particle-size distribution, Olsen extractable phosphorus, water total alkalinity, hardness, dissolved oxygen and water-extractable phosphorus) were studied to determine the impacts of variation in these properties on the fish biology and survival in the pond. Result showed that the clayey and very low permeable of bottom soil of pond was a suitable condition for anaerobic respiration, as a result of producing organic acid and alcohol, formation of hydrogen sulfide, nitrite, manganese, ferrous iron, and methane that makes hard poisonous conditions which negatively affect on fish survival and growth, it reduced the concentration of dissolved oxygen in the water of pond to 5.96±1.0 (mgL-1)..In addition long days, (16 hour), and high temperature degree ,40-50C°, during summer season, and high fertilizing led to increase the accumulation of organic matter (%) 5.84± 1.53 that serve the raw material of anaerobic respiration leading to high mortality and sensitivity to disease among fish in the pond.

RAYLEIGH FADING - SHADOWING OF OUTDOOR CHANNELS ANALYSIS BASED ON SNR-PDF MODEL
No full textThe outdoor transmission channels condition in multiple wireless signals systems changes continuously due to signals transfer path characteristics. The path loss, multiple reflected rays Rayleigh fading and shadowing presents an important factor that effects inconsistent with signals propagation through the wireless channels of communication systems. The solutions for these effects will contribute to minimize the error probability of transferred data and maximize the data rate in high speed systems. This paper deals with the analysis of error probability using Probability density function (PDF) model of Signal to Noise ratio (SNR) for different values of transmitted signals power at outdoor receiver of multi users systems. The proposed approach use Rayleigh fading channels, 2GHz carrier frequency, (0-30) dB SNR, (0.1,0.2,0.3), (1,2,3) and (10,20,30) PW. The relationship between error probability and SNR has been studied to determine efficient transmission channels. The proposed channel model has been simulated and analyzed using MATLAB R2012b software under different users power signals values. The obtained results have showed accuracy as well as efficiency of the proposed method where the error probability is decrease when the SNR increase and the error probability decrease when decrease in the transmitted power signal.http://dx.doi.org/10.30572/2018/kje/100209
