The in vitro adulticidal effect of aqueous and methanolic extracts of Capparis decidua stems, Moringa oleifera leaves and albendazole was investigated against Fasciola gigantica worms. Three different concentrations of the plant extracts 1200, 600, 300 ?g/ml and 1%, 0.5%, 0.25% of albendazole were used. Albendazole drug exhibited highest mortality (P < 0.05) after 11 hours. C. decidua stems methanolic extract showed significant (P < 0.05) toxic effect on F. gigantica adult worms after 13 h at 1200 ?g/ml compared with the low concentration of albendazole (0.25%). Moreover, methanolic extract of M.oleifera leaves did not show any significant (P > 0.05) fasciolicide activity against adult worms at the concentrations used in this study compared with albendazole and the negative control. These results demonstrate that C. decidua stems may have anthelmintic activity especially at higher doses.

The aim of this study was to assess the microbial contamination of sheep carcasses before and after wearing gloves, apron, mask and caps at slaughterhouse in Khartoum state. A total of 600 swab samples were collected from different operational points namely; skinning, evisceration and washing from the site of neck, shoulder, brisket and rump. The Total Viable Count (TVC) was used to assess bacterial these sites before and after treatment by wearing protective clothes. In addition 60 swab samples were taken from hands of workers and their knives also before and after sterilization by tap water at 82 �C. The results revealed that there was reduction in the bacterial counts according to the anatomical site of sampling at operational points with range of 2.39�1.03 log10 cfu/ cm2, 2.30�1.11 log10 cfu/cm2, 2.35�0.98 log10 cfu/ cm2 in the neck after treatment (p? 0.05). respectively The viable counts of the workers� hands reduced to 2.23�0.99 log10 cfu/ cm2, 2.12�1.33 log10 cfu/ cm2, 2.12�1.01 log10 cfu/ cm2 at different operational points (P<0.05). The presence of bacteria in the meat in the slaughterhouse indicated that unhygienic processing of meat? 2013 Sudan University of Science and Technology. All rights reserved

Salem, H.A.
In this research a prototype of a hafir is lined-up with HDPE geomembrane. This lined-up hafir was investigated for the dissipation of water to the bottom and to the sides of the hafir. The main objective of this research was to study the effect of lining-up the hafir on the prevention of water from being dissipated to the bottom and the sides of the hafir. Generally, water should stay in hafirs up to the next rain season. This research succeeded to prevent the water dissipation to bottom and sides of the hafir by lining it up with HDPE geomembrane. This research as well set a solution for the reduction of natural evaporation of water by covering the top surface of the hafir by a thin sheet of HDPE with a reflecting material. Some suggestions are mentioned for treating the water chemically and physically so as to be drinkable for man and animal.

This article investigated the personal satisfaction of wearing Columbia resin CR-39 ophthalmic lenses in Khartoum state; it investigated comfort, durability and safety of such lenses. The investigation was carried out by questionnaire on 304 subjects. Participants' ages ranged between 5 and 65 years with a mean of 32.22�12.81 years, 178 males versus 126 females. The collected data were analyzed using the statistical package SPSS. The results revealed that significant element of comfort 96% in vision was noted in using CR.39 ophthalmic lenses, in addition to 99.7% of the subjects stated that CR.39 lenses have light weight compared with ophthalmic glass lenses; however 89.5% users clearly stated that durability was poor for those type of lenses; while 96% of the participants pointed that the lenses were safer compared to the ophthalmic glass lenses. It was found that scratches were the main cause of lens colour changes p=0.001 and visual blurring p=0.007, however; spectacles, cases were found to be a significant cause of scratches. Self selection for clear CR-39 among other types of lenses, has a significant role in discomfort p=0.046; 81.9% of participants had chosen plastic lenses by themselves, while 83.1% preferred plastic for their new spectacles. The causes for changing spectacles were found to be scratches (93%) and discomfort (80%). Blurring of vision was found to be in 57.6% and colour changes were 41.1% of the studied group. Based on evaluation by participants the study concluded that CR.39 lenses are comfort, safe compared to glass lenses. However, due to scratches they have short durability
