...Show More Authors

Six isolates of A. pullulans were collected from many sources including Hibiscus sabdariffa (Roselle), old Roofs of houses and bathroom surface that referred as Ap ros1, Ap or2, 3, 4 and Ap bs5, 6 respectively, all these isolates were identified based on morphological characteristics and nutritional physiology profiles, all were able to utilize various carbon and nitrogen sources such as glucose, xylose, sucrose, maltose, ammonium sulfate, ammonium nitrate and ammonium chloride, also they showed positive test for starch and amylase, while α-cellulose, ethanol, and methanol were could not be assimilated and could not grow in 0.05% cycloheximide, the other tests referred to different results among isolates, the Ap ros1 isolate from Hibiscus sabdariffa (Roselle) was selected for production of pullulan.

           Four bacterial strains of two gram (+) and two gram (-) were chosen for the tests. The effect of pullulan coating on bacterial growth was observed in all tested strains, it was 63, 65, 70 and 75% for Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Salmonella typhimuram respectively.

The weight loss of uncoated peach was 3.2, 4.8, 6.1, 7, 7.2, 8.3 and 9.1%, while in coated peach with 10% pullulan were 3.1, 4.5, 5.8, 6.2, 6.8, 7.9 and 8.9%, and in coated peach with 20% pullulan were 2.9, 3.8, 4.1, 4.6, 5.8, 6.4 and 7.6%, when these samples are stored at 3, 6, 9, 12, 15, 18 and 21 days respectively that stored at 25°C, and when uncoated and coated peach with 10 and 20% pullulan stored at 4°C . The weight loss in uncoated peach was 0.01, 0.06, 0.16, 0.23, 0.35, 0.46, 0.6, 0.68, 0.73 and 0.75%, while in coated peach with 10% pullulan were 0.01, 0.05, 0.12, 0.16, 0.2, 0.3, 0.5, 0.58, 0.64 and 0.71%, and in coated peach with 20% pullulan were 0.015, 0.02, 0.04, 0.08, 0.1, 0.12, 0.18, 0.3, 0.46 and 0.5%, when these samples are stored at 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 days respectively.

The weight loss of uncoated pear was 1.4, 2, 2.6, 4.4, 5.5, 6.4 and 7.2%, while in coated peach with 10% pullulan were 1.2, 1.6, 2, 2.4, 4.3, 5.2 and 6.6%, and in coated peach with 20% pullulan were 0.8, 1, 1.4, 1.6, 3, 4.6 and 5.4%, when these samples are stored at 3, 6, 9, 12, 15, 18 and 21 days respectively that stored at 25°C, and when uncoated and coated pear with 10 and 20% pullulan that stored at 4°C. The weight loss is 0.02, 0.07, 0.14, 0.16, 0.3, 0.33, 0.44, 0.45, 0.52 and 0.54%, while in coated peach with 10% pullulan were 0.02, 0.06, 0.11, 0.16, 0.21, 0.3, 0.36, 0.38, 0.44 and 0.46%, and in coated peach with 20% pullulan were 0.01, 0.05, 0.08, 0.09, 0.1, 0.16, 0.19, 0.24, 0.26 and 0.28%, when these samples are stored at 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 days respectively.

Abstract

There have been a number of positive developments in inclusive education in many different countries, recognizing that all students, including those with disabilities, have a right to education. Around the world, educators, professionals, and parents are concerned about including children with disabilities in mainstream schools along with their peers. As a result of this trend, a number of factors are contributing, including the increasing importance of education in achieving social justice for pupils with special education needs; the right of individuals with disabilities to attend mainstream schools together with their typically developing peers; the benefit of equal opportunities for everyone in achie

Evaluation of the Performance of a Locally Manufactured Palm Service Platform
...Show More Authors
Abstract<p>A field experiment was carried out in one of the orchards of Al-Qassim district in Babel Governorate to find out the ability of a locally manufactured platform to serve palm trees by working in flat and uneven orchard land, palm tree heights of 4, 8, and 12 meters, and it performs pollination, pruning and harvesting services. The time of ascent and descent, the palm service, and the palm/hour productivity were measured. A randomized complete block design with three replications used a split split-plot arrangement. The nature of the land (flat or uneven) represented the main plots, the height of the palm trees (4, 8, 12) meters, the sub-plots, and the palm service operations (pollinati</p> ... Show More

The cities are not yet a temporal status in the process of the human and civilization development. The cities consider as a life pattern, this mean that people cannot live without cities, which surround us. Several phenomena like globalization, revolution of information, technical development, increased of consumption, do not confirmed without the living in cities. The urbanization – in its simple meaning – means transferring from rural community to city community. In other word, it means that socioeconomic changes happened subject to the patterns and conditions of the urban life. Each government depend a certain policy, this policy contains set of plans and programs, that targeting to affect the population factors and the st

Removal of Sulfate from Waste Water by Activated Carbon
...Show More Authors

Activated carbon was Produced from coconut shell and was used for removing sulfate from industrial waste water in batch Processes. The influence of various parameter were studied such as pH (4.5 – 9.) , agitation time (0 – 120)min and adsorbent dose (2 – 10) gm.

The Langmuir and frandlich adsorption capacity models were been investigated where showed there are fitting with langmmuir model with squre regression value ( 0.76). The percent of removal of  sulfate (22% - 38%) at (PH=7) in the isotherm experiment increased  with adsorbent mass increasing. The maximum removal value of sulfate at  different pH experiments is (43%) at pH=7.

Effect of transglutaminase on mechanical and barrier properties of edible films made from soybeen and why protein isolate
...Show More Authors

This study was aimed to study the effect of adding transglutaminase (TGase) on the mechanical and reservation properties of the edible films manufactured from soybean meal protein isolate (SPI) and whey protein isolate(WPI). The results showed an improvement in the properties with increase in the WPI ratios. Thickness of the SPI films amounted 0.097 mm decreased to 0.096 mm for the WPI: SPI films at a ratio of 2:1, when TGase was added decreased to 0.075 mm. While the tensile strength increased from 7.64 MPa for SPI films to eight MPa for the WPI: SPI films at a ratio of 2:1, when TGase was added increased to 11.04 MPa. Also, the elongation of the WPI: SPI films at a ratio of 2:1 presence of the TGase decreased to 40.6% compared wit

Bioadsorption of Heavy Metals From Industrial Wastewater Using Some Species of Bacteria
...Show More Authors

Three isolated bacteria were examined to remove heavy metals from the industrial wastewater of the Diala State Company of Electrical Industries, Diyala-Iraq. The isolated bacteria were identified as Pseudomonas aeruginosa, Escherichia coli and Sulfate Reducing Bacteria (SRB). The three isolates were used as an adsorption factor for different concentrations of Lead and Copper (100, 150, and 200 ppm.), in order to examine the adsorption efficiency of these isolates. In addition, the effect of three factors on heavy metals adsorption were examined; temperature (25, 30, and 37 ?C), pH (3 and 4.5) and contact time (2 and 24 hrs). The results showed that the highest level of lead adsorption was obtained at 37 ?C by E. coli, P, aerugenosa and

Producing Bone China with local and manufactured materials as substitutes for the traditional materials
...Show More Authors

This research studies the possibility of producing Bone China with available local and geological substitutes and other manufactured ones since it’s traditionally produced by Bone ash, Cornish stone, and China clay, while the substitutes are Kaolin instead of China clay and Feldspar potash instead of Cornish stone. Because of the unavailability of Feldspar in Iraq, it was substituted with the manufactured alternative Feldspar. Bone ash was prepared from cow bones with heating treatments, grinding and sifting. The alternative Feldspar was prepared by chemical analysis of the natural Feldspar potash with local materials that include Dwaikhla Kaolin, Urdhuma Silica sand, Potassium Carbonate, and Sodium Carbonate. The mixture was burned at
