Abstract: Objective: Two different concentrations of ketamine 0.5 mg/kg, 0.25 mg/kg were applied to both tonsils perioperatively to check analgesic effect postoperatively in children. This study done at Department of anesthesia and otorhinolaryngology, faculty of medicine, Al-Azhar University hospitals, and the medical ethics committee. The study was conducted in the ENT operating theatre, Al-Azhar University Hospitals, from Jan. 2017 to June 2018. Methodology: We divided patients into 3 groups K1, K2 and S each group 25 patients, group K1 had 0.25 mg ketamine, group k2 had 0.5 mg ketamine and group S had normal saline as a control group. These groups assessed intraoperatively by Heart rate and main arterial pressure (MAP) were recorded at the intervals together with Ventilation parameters. Postoperative pain assessment by using Children’s Hospital of Eastern Ontario Pain Scale (CHEOPS). The sedative condition was assessed with the Wilson sedation scale at 5, 15, 30, and 60 min after entrance to the PACU. CHEOPES was recorded only when patient modified Wilson sedation score was one. Incidences of postoperative complications as: blood loss, dysphagia, nausea and vomiting were noted and demonstrated; hallucinations will be observed and recorded. Results: There were no significant differences among the groups regarding age, gender and weight. There were no significant differences among the groups with respect to the demographic data, duration of surgery or anesthesia, and intraoperative blood loss. As regarding hemodynamics, mean blood pressure was significantly lower in group (K1) than group S (control group) at 20 and 30 minutes after injection of ketamine and significantly lower in group (K2) than group S (control group) at 20 and 30 minutes after injection of ketamine with no difference between group (K1) and (K2). There was a significant statistical difference in analgesia duration per hours and frequency of analgesics used over 24 hours between three groups, the duration was longer in group (K1) and (K2) and frequency of analgesics used over 24 hours (P value < 0.05). Regarding postoperative complications, there was no significant statistical differences as regard nausea and vomiting, but the percentage of dysphagia is significantly higher in group S (control group) than group (K1) and group (K2). Conclusions: In our study, we found that preincisional peritonsillar infiltration of 0.25 mg/kg or 0.5 mg/kg of ketamine given at approximately three minutes before surgery provides efficient pain

Abstract: Relationship marketing, just as the name implies is simply the art of developing a personal relationship with your customers. Anyone can start a business but not everyone can build a strong customer relationship. The growing importance of relationship marketing hasincreased interest in the role of consumer trust and satisfaction in establishing, developing, and maintaining successful relational exchanges. There are many different relationship marketing tactics implemented for retaining customer. However, some of those tactics did not affect customer loyalty effectively, and switching behaviors frequently occur among most of targeted customers. Therefore, this study is aimed to investigate the effect and relationship ofcustomer relationship marketing tactics on customer satisfaction, trust and customer loyalty, by focusing on mobile service providers in Vadodara, India . A cross-sectional relationship between relationship marketing tactics, relationship quality (trust and satisfaction) andcustomer loyalty was used. Findings - The results shows positive relationship between the variables included in the study. The findings contribute to understanding of the relationships between different elements of customer relationship marketing practices, relationship quality and customer loyalty, which provide critical implications for managers of service organizations; and highlight directions for future research.

Abstract: The present study was undertaken to investigate the effect of the ethanolic extract of Syzygium aromaticum to albino rats. Forty eight Albino rats were employed to test the safety and the anti-inflammatory effect of the extract. Safety of the extract was examined on experimental animal’s model at three dose levels of the extract orally in daily doses for three weeks. Effects of S. aromaticum on rats revealed no significant effect on biochemical or haematological parameters. The anti-inflammatory effect of the extract was tested in four equal groups; groups 1 and 2 were treated with 250 and 500 mg/kg of the extract, respectively, group 3 was treated with indomethacine and group 4 was the untreated control. Carrageenan was used as an acute form inducer of inflammation. Indomethacine, the non-steroidal anti-inflammatory drugs (NSAIDs), was used as a reference compound. Oedema size was monitored at the 1st, 2nd, 4th, 6th and after 24

Abstract: The performance of UASB (Up-flow Anaerobic Sludge Blanket) reactor was investigated in the present study for treatment of flax retting wastewater. Batch and continuous experiments on a pilot scale were designed. The initial seed for granules (bacteria acclimation) formed earlier was from municipal sewage treatment plant with VSS of 18 - 20 g/L. Batch experiments proved that the sludge retention time (SRT) was 77 days. Under steady state conditions, continuous experiments were conducted at organic loading rates (OLRs) in the range of 1.2 to8.6 kgCODs m3·d1, where the hy- draulic retention time (HRT) decreased from 72 to 12 hrs. The results proved that the UASB technology provides good COD removal efficiency from 64.5% to 90.5% as COD loading rate decreased and good biogas production at proper food: micro-organism (F:M) ratios.

Abstract: Objective: Studying sub endometrial vascularity and blood flow in cases using intrauterine contraceptive devices for contraception with and without menorrhagia compared to cases not using intrauterine contraceptive devices. Methods: Three hundred and fifteen women attending gynecology and family planning outpatient clinics in the maternity hospital, Ain Shams University were included in the study. They were classified into three groups, 105 women using IUCD with menorrhagia (group I), 105 women using IUCD without menorrhagia (group II), and 105 normal controls not using IUCD (group III). After excluding local causes for bleeding, blood disease or any medical disorders, transvaginal ultrasound including three dimensional power Doppler (3DPD) ultrasound was done for all women. Right and left uterine artery pulsatility index (PI) and resistance index (RI) were calculated, subednometrial blood flow RI and PI were obtained then 3DPD Vascular indices (VI, FI and VFI) of subendometrial blood flow were obtained for all cases. Statistical analysis was done to compare between the three groups. Results: A significant statistical difference was found as regards subendometrial vascularity indices, while there was no difference as regards bilateral uterine arteries Doppler indices in the three groups. Conclusion: Subendometrial vascularity in cases of menorrhagia with IUCD was markedly higher than in cases without menorrhagia and cases with no IUCD. 3DPD may be used for selection of cases prior to insertion of IUCD.

Abstract: The impact of different levels of dietary vitamin-E supplementation on broiler production and immunity was investigated. One hundred and sixty birds were randomly assigned to four equal groups of forty birds each. Birds were fed starter and finisher diets supplemented with different levels of vitamin-E (0, 400, 800 or 1200 mg/kg diet). Statistical differences among treatments were noted for body weight at the sixth week of age, which increased significantly (P< 0.05) by elevating vitamin-E levels, while body weight gain, feed consumption and feed conversion were not influenced by dietary treatments. The white blood cells (WBC`s) counts increased significantly (P<0.001) with elevating the vitamin-E levels, whereas, the red blood cells (RBC`s), hemoglobin (Hb), mean corpuscular volume (MCV) and packed cell volume (PCV%) were not statistically affected by any of the treatments. The immunological parameters were significantly (P<0.001) affected by dietary treatments. Increasing level of vitamin-E caused certain structural alterations in thymus gland rather than bursa of Fabricius comparing to that of low levels

Abstract: To help universities achieve their goals, it is important to align managerial functionalities side by side with educational aspects. Universities consume University Management Information Systems (UMIS) to handle managerial aspects as they do with Learning Management Systems (LMS) to achieve learning objectives. UMIS advances LMS by decades and has reached stable and mature consistency level. LMS is the newly acquired solution in Universities; compared to UMIS, and so adopting LMSs in universities can be achieved via three different deployment approaches. First approach believes in LMS ability to replace UMIS and performing its functionalities. Second approach presents the idea of extending UMIS to include LMS functionalities. Third approach arises from the shortages of the two proposed approaches and present integration between both as the appropriate deployment approach. Service Oriented Architecture (SOA) is a design pattern that can be used as a suitable architectural solution to align UMIS and LMS. SOA can be utilized in universities to overcome some of information systems’ challenges like the integration between UMIS and LMS. This paper presents the current situation at Mansoura University; Egypt, presents integration as the most suitable solution, and evaluates three different implementation techniques: Dynamic Query, Stored Procedure, and Web services. Evaluation concludes that though SOA enhanced many different aspects of both UMIS and LMS; and consequently university overall. It is not recommended to adopt SOA via Web services as the building unit of the system, but as the interdisciplinary interface between systems.

Abstract: In the present study, conventional bacterial isolation, bacteriophage-based assay (FAST Plaque TB) and Polymerase Chain Reaction (PCR) were evaluated for detection of Mycobacterium tuberculosis complex. A total of 47 mycobacterial isolates consisting of 38 isolates of Mycobacterium tuberculosis complex and 9 isolates of mycobacteria other than M. tuberculosis complex were used in this study. In addition, nine reference strains of Mycobacterium consisting of 7 Mycobacterium tuberculosis, one strain of Mycobacterium flavescens, one srtrain of mycobacterium duvalii were also used in this study. Conventional isolation is laborious, cumbersome and time consuming where it takes as long as 2 months for definitive diagnosis. The phage assay is sensitive and it takes only two working days. PCR is a rapid assay and definitive diagnosis of tuberculosis infection could be made possible within the same working day. The described bacteriophage-based assay could be used as rapid, sensitiveand specific method to support the currently available conventional methods used for detection of Mycobacterium tuberculosis in developing countries.

Abstract: Astrocytomas are tumors that arise from astrocytes—star-shaped cells that make up the “glue-like” or supportive tissue of the brain. Astrocytomas can appear in various parts of the brain and nervous system, including the cerebellum, the cerebrum, the central areas of the brain, the brainstem and the spinal cord. The main objective of this study was to detect the sensitivity of the CT scan in diagnosis of the brain astrocytoma, in patients who were confirmed as brain gliomas using computerized tomography of the brain versus brain tissue biopsy after surgery. One hundred and one patients were included in this study. Bio-data collected for these patients (age, gender), radiographic appearance, contrast enhancement and the site of the tumor, were statistically analyzed. Out of the 101 patients with brain gliomas, 52 (51.5%) were male whose ages ranged between 1 and 80 years, and 64 (63.4%) cases were diagnosed as astrocytoma by CT. This study concluded that the CT brain was sensitive in the diagnosis of brain astrocytomas.

Abstract: Since the pesticides are considered as an essential component for crops production through controlling pests, they have shown a negative effect on crops and soil environment when used intensively. This experiment was conducted at Wadi Soba farm (Sharq Elneel) Khartoum, Sudan. It aimed to study the effect of Sevin residuals on carrot growth and Azotobacter spp. colonies growth. Carrot planted in late February 2013, Sevin pesticide (2.5 L/ha and 5 L/ha) was added to estimate plant height, dry weight, the number of plant leaves and the number of Azotobacter spp. colonies isolated from the carrot rhizosphere (0 - 15 cm). The obtained results showed that the Sevin recommended dose (2.5 L/ha) relatively had a positive effect on the plant height, dry weight, and the number of plant leaves. The average of plant height for recommended dose was 59.67 cm compared to control (53.67 cm) and high dose (27.33 cm). The average of plant dry weight obtained by the recommended dose was 503.33 g and for control was 476.67 g and for high dose was 166.7 g, it decreased 67% from control and recommended dose. The average of plant leaves number were 25.34, 13.66 and 21.33 for recommended dose, high dose and control respectively, the number of leaves increased about 16% by recommended dose and decreased 35% by high dose. The average of Azotobacter spp. colonies obtained by high dose of Sevin demonstrated a lower numbers which were 20 × 104, 5.67 × 106 and 0.33 × 108 compared with control (78.33 × 104, 44 × 106 and 15.33 × 108) and the recommended dose (64 × 104, 33 × 106 and 7 × 108). The high dose of Sevin had a negative effect on both carrot growth and Azotobacter spp. colonies growth.
