Abstract: Petrogpaphical and geochemical studies of the mafic rocks of southern part of Bela Ophiolite (BO) is made to infer tectonic setting of the area. The BO is the largest (~450km) and most complete ophiolite in Pakistan, linked with Neotethyan ophiolitic belt which extend from European Alps to Asia. Petrographically, the majority of mafic rocks appeared as amygdaloidal and vesicular porphyritic basalt. Large phenocryst of feldspar, olivine, ortho- and clinopyroxene are present with in fine-grained groundmass of nearly similar composition. Numerous small needles of black opaque minerals are dispersed in the fine groundmass. The petrographic study revealed two stages of crystallization. In the first step, phenocrysts are formed while in the second step, pillow basalt at MORB setting were fractionate during the rapid cooling in cold seawater. Based on TAS diagram, the rocks of the study area appear as basalts. These rocks displayed tholeiitic characteristics and showed relevancy with metaluminous type of rocks. Trace element assemblage of the studied rocks plots on various discrimination diagrams as ocean floor tholeiite, initially formed at Mid-ocean Ridge setting. The subsequent subduction phase generates SSZ ophiolite, forming Island-Arc Tholeiite (IAT) and Back-Arc Basin Basalts (BAB).

Abstract: Potato cultivars and wild species are varying diversity in their response to PSTVd infection. It was found that, all the cultivated potatoes were susceptible to PSTVd infection except (Draga and Spunta), (Hermes) and (Nicola) were tolerant, hypersensitive and low resistant, respectively. On the other hand, all wild species were tolerant except S. etuberosum was immune and S. chacoense was rather moderate resistant. Five of the RAPD and four ISSR primers were used to detect DNA markers for PSTVd-resistant among cultivated and wild potato species. These primers revealed polymorphism depending on bands number and level of detectable polymorphism of primers. Thus, the hypersensitive plants of Hermes appeared (10), the tolerant plants of Draga showed (8) markers with both of RAPD and ISSR, and the resistant plants of Nicola revealed (3) one marker by RAPD and two markers by ISSR. Also, the immune plants of S. etuberosum scored the highest markers for resistant plants to PSTVd (11) markers (one in RAPD and 10 with ISSR), then the resistant plants S. chacoense displayed (1) with RAPD.

Abstract: Cucumber (Cucumis sativus L.) is considered one of the most important vegetable crops, under greenhouse conditions in Egypt. Application of black and white nets and polyethylene sheet affect on environmental factors under greenhouse conditions where as environmental factors (temperature and relative humidity) were higher with application of polyethylene sheet comparing with application of black and white nets. There was positive relationship between environmental (temperature and relative humidity) factors and population of aphids, spider mites, thrips and whitefly by using black and white nets and polyethylene sheet. Population of different pests were increased as well as increasing temperatures and decreasing relative humidity. Maximum population of aphid and whitefly were observed during May, but maximum population of spider mites and thrips were observed during June. Population of aphid was most frequent with using different shading nets, while population of spider mites and thrips were more frequent, While whitefly pests was less frequent. Populations of insects were more high when using polyethylene sheet than black and white nets.

Abstract: This paper highlights the detailed methodology of mathematical model formulation for the surface roughness during the dry turning process. This paper also represents the detailed about the formulation of field data based model to analyze the impact of various machining field parameters on the surface roughness of aluminum 6063 during the dry sturning operation. In Indian scenario where majority of total machining operation are still executed manually which needs to be focused and develop a mathematical relation which simulate the real input and output data directly from the machining field where the work is actually being executed. The advantages and limitations of the developed mathematical models are identified and the models are classified in terms of application range and goals. The findings indicate that the topic understudy is of great importance as no such approach of field data based mathematical simulation is adopted for the formulation of mathematical model.

ABSTRACT: Cymbopogon citratus (Lemon grass) and Momordical charantia (Bitter melon) has been in use over time for medical purposes. In this study, aqueous and methanol extracts of both plants were tested for antibacterial activity against control strains of Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aeruginosa and Proteus mirabilis using broth dilution technique. Cymbopogon citratus was found to be inhibitory to Proteus mirabilis at 79mg/ml and 39.5mg/ml for others (aqueous extract); 19.75mg/ml for Klebsiella pneumoniae and Pseudomonas aeruginosa and 39.5mg for others (methanol extract) and bactericidal at 79.0mg/ml for Pseudomonas aeruginosa and 158mg/ml for others (aqueous extract); 79.0mg/ml for Staphylococcus aureus and Pseudomonas aeruginosa and 158mg/ml for others (methanol extract). Momordical charantia was inhibitory at 20mg/ml for Staphylococcus aureus and 40mg/ml for others (both aqueous and methanol extract) while it was not bactericidal except at 80mg/ml to Pseudomonas aeruginosa (both extract) and to Proteus mirabilis (methanol extract only) It is recommended therefore that various plants alike) should be explored for their antibacterial activities as this could open ways for combating fast appearing resistant strains of pathogenic organisms.

ABSTRACT: One hundred nasal swabs were collected from 50 males and 50 females students of University of Port Harcourt were examined for Staphylococcus aureus using standard bacteriological methods. Thirty- two percent of the 100 samples were found to be carrying Staphylococcus aureus in their nasal cavity. This study showed that there was a significant difference between sex for carriage rate of S. aureus [18.0% vs. 46.0%, P <0.05]. The study also showed that there was no significant difference between age groups for either carriage rates of S. aureus (35.3% vs. 25.0%, P >0.05). It showed that Methicillin susceptible S. aureus (MSSA) [62.5%] was most predominant over Methicillin resistant S. aureus (MRSA) which was 37.5% and that there was a significant difference between carriage rate of MRSA and MSSA [37.5% vs. 62.5%, P <0.05].

Abstract: This study investigated the gender based disparities in the prevalence of pulmonary Tuberculosis in the Port-Harcourt metropolis of Rivers-State, Nigeria. A total of 1038 sputum samples were collected from in and out patients of the University of Port- Harcourt Teaching Hospital for a period of one year. Three (3) deep cough samples were collected per patient over a period of three days. The samples were examined macroscopically and microscopically. The Ziehl-Neelsen technique for the detection of Mycobacterium tuberculosis in sputum was carried out. The sputum samples were also cultured using MacConkey, Chocolate and Blood agar. Biochemical tests were used for identification. Of the 1038 samples collected, 348(33.5%) tested positive and 690(66.5%) were negative for acid fast bacilli (AFB). Of the 348 positive AFB samples, 149(23.7%) were males and 199(48.5%) were females showing a higher prevalence in females than males. The study showed a significant difference in TB infection between male and female subjects (23.7% vs. 48.5%, P<0.05). It also showed no significant difference between overall positive and negative female subjects at 5% and 10% (P>0.05). In conclusion, there seems to be a gender difference in the inception, progression and outcome of TB infection. Continued research on gender and tuberculosis need to be geared in the direction of ascertaining the magnitude of gender disparities in tuberculosis, from contracting the disease to successful recovery and rehabilitation.

Abstract: Background: Cryptosporidium species are protozoan parasites that cause infection and diarrheal illness in a wild range of mammalian species. There are 20 described species of cryptosporidium of which cryptosporidium hominis and C. parvum are the most frequently detected. C.hominis infection is more common in developing countries. Objective: to detect cryptosporidium infection in clinical samples from pediatric suffering from diarrhea. Patient and Methods: 177 children, in the age group from 1 to 5 years old, suffering from diarrhea, selected from the gastro eanterology outpatient clinic, children Hospital, Cairo University with 35 apparently healthy children in the same age as control group were included in the study. Cases were screened using RIDA Quick Cryptosporidium Coproantigen detection kit. In addition, stool specimens were examined following the kinyoun acid-fast staining method. Results: 27 children in the study group were positive for cryptosporidium infection using antigen detection method (15.3%), while 20 were positive using the acid-fast technique (11.3%). All children in the control group were negative for cryptosporidium infection. Conclusion: cryptosporidium infection is one of the important causes of diarrhea in children below 5 years of age and RIDA Quick antigen detection test proved to be a useful mean for diagnosis in fresh fecal samples.

Abstract: This study investigates the impacts of oil disposal in open seas on groundwater pollution in coastal aquifers, based on one site specifications. The location of the site is Abu Qir, near Alexandria and the designed plant capacity is 800m3/hr. The major sources of oil are the ships spills. Oil was found in the sea water close to the plant site. Therefore, it was decided to replace sea water by groundwater through beach wells. To satisfy the desired plant capacity of fresh water, 4 deep groundwater wells are needed with a total capacity of about 800 m3/hr, in addition to 3 wells as stand-by to keep the groundwater discharge as required during emergency conditions. The 7 wells are planned to operate alternatively to keep the groundwater discharge as required. The maximum allowable pumping value is 1200 m3/hr. Chemical analysis of groundwater indicated the existence of Oil at some locations which calls more investigations on its extent, at present, and in the future with the operation of the wells. Accordingly, a forecast is made to investigate the extent of the Oil plume through the aquifer in terms of concentration and extent. This is achieved through the numerical simulation of the aquifer system by Visual MODFLOW 4.2. The calibrated model was used to test the impacts of proposed scenarios on the sustainability of the plant capacity of saline water at present and in the future. The results have demonstrated that:1)All scenarios of pumping are accepted if the drawdown does not affect the stability of the project buildings, 2) The Oil concentration decreases with depth before any operation; 3)The Oil concentration will decrease with time; 4)The Oil concentration will decrease with pumping ; 5)The maximum Oil concentration in the model area before pumping is 16 mg/l at 2009 and will be 7 mg/l after 40 years; 6)The maximum Oil concentration in the model area after pumping at the maximum capacity possible (1400 m3/h for 7 wells) is expected to be 14 mg/l at 2009 and is expected to be 5 mg/l after 40 years at 30m depth and 7) The maximum Oil concentration in the model area after pumping at the maximum capacity possible (1400 m3/h for 7 wells) is expected to be 4 mg/l at 2009 and is expected to be 0.9 mg/l after 40 years at 70m depth. This primary exercise indicates the safe dependence on saline groundwater in desalination. However, monitoring systems are recommended to ensure the adequacy of the exercise, accompanied by post-auditing of the models.
