Histopathological Study on Induced Eeffects of Cadmium on Liver, Gizzard and Kidney of Larus argentatus
Get PDFThe study was carried out on the effects of cadmium (Cd) on liver, gizzard and kidney of Larus argentatus. Significant alterations were observed after the treatment of high and low dose of cadmium chloride injected to Larus argentatus. Investigation of the effects of Cd on body tissues was done by sectioning of fixed tissue by paraffin section techniques. Major changes were noted at high dose of cadmium chloride in liver, kidney and gizzard. While, under low dose of cadmium chloride, mild to moderate changes in hepatocytes around blood vessels in liver; reduction in thickness of epithelium and muscular layer in gizzard; and slight alterations in arrangement of tubules of loop of henle in the kidney of proximal convoluted tubules with granular cytoplasm were observed. No lesions were found in the mentioned body tissues of Larus argentatus of control group
Software Project Management as Team Building Intervention
Get PDFThe courses of software project management (SPM) and Software engineering (SE) are regularly taught at undergraduate degree program in computer science. Students of these programs also have to undertake projects as part of various courses during their degree program. The purpose of this research is to assess whether the software engineering or the software project management course had enhanced the cohesion among team members while undertaking a six month or a year-long project. The teaching of these two courses is considered as a team building intervention in this research. A total of 167 students returned a modified version of Group Environment Questionnaire distributed to 200 students. Off these, 81 were those who had taken the SE course and subsequently did a project before they had taken SPM course. The rest of the students (85) consisted of those who had taken SPM and had undertaken final project. The results of this paper indicates that the SPM as compared to SE as a team building intervention had a better effect on team cohesion. The paper has successfully identified a single course that can enhance the performance of students as a team in contrast to proposing all the courses taught at the undergraduate computer science degree program as intervention for better team building and team work as proposed by Hogan & Thomas, 2005
Prevalence of under Nutrition and Associated Factors among Khat Chewers in Khat Chewing Shops at Gulalle Sub City, Addis Ababa, Ethiopia
Get PDFThere is studies limitation regarding the effect of khat chewing on nutritional status. Community based comparative cross-sectional study had been conducted from March to June, 2015; with cluster sampling and systematic random sampling techniques for khat chewers and non-khat chewers respectively. The data was collected by using interview administered questionnaire, observation and weight scale measurement among 504 study participants.The study revealed that from entire khat chewers 52(20.5%) of them and of non-khat chewers 34(13.5%) of them were underweight. Khat chewers were 2.102 times more likely underweight compared to those non-khat chewers. khat chewers who had meal twice per day were 2.856 time more likely underweight. Khat chewers who used animal and animal products as their main meal component daily were 0.413 times less likely to be underweight; Whereas the odds of underweight was 26% times less likely among khat users who intake two liters of fluid per chewing session. In other case, those who chewed khat for 2-3 hours per session were 0.231 times less likely to be underweight.Under nutrition is a public nutritional status problem in which khat chewers are more affected. Khat chewing conditions and meal conditions including amount of fluid consumed per chewing session are factors that affect the nutritional status of the khat chewers. Minimizing amount of khat consumed per session, shortening of khat chewing session length and increasing amount of fluid intake more than two liters per chewing session and nutritional management with nutritionist advices are important points
Assisting Disabled Persons in Online Shopping: A Knowledge-Based Process Model
Get PDFKnowledge management is gaining more and more attention from business management with a consideration of knowledge as a critical intellectual resource for organization in getting successful competitive advantage. The aim of integrating of KM processes with business processes is to add value, provide supports and increase productivity. The role of technology for knowledge management processes, i.e., capture, codification, dissemination, is very important. Organization are readily adapting e-commerce and shifting business activities over web to maintain competitive advantage and building strong relationship with suppliers, employees, and customers.E-retailing emerged as a new way of shopping; people search/browse products online, compare and purchase with great convenience. It also eliminates barriers that disabled persons encounter when they visit shopping stores such as inaccessible entrance for wheelchair shoppers. However, still there is a significant part of disabled population is neglected from getting benefits of online shopping because of lack of accessibility features in websites. Understanding the knowledge about them can lead business managers to better facilitate in online shopping. This paper proposed a model based on the Nonaka Knowledge Spiral model to support business managers to capture knowledge about disabled person’s online shopping behaviors; supplement this knowledge into their website to support disabled persons. This also helps business managers to capture the un-attended population in their business net
Combining Ability Estimates for Yield and Fiber Quality Parameters in Gossypium Hirsutum L. Hybrids
Get PDFGeneral and specific combining ability effects were discriminated in different parents and offspring to isolate the potential of genotypes used in diallel system to attain the genetic inheritance pattern ascertain with the nature of gene action. A six-by-six, hirsutum diallel excluding reciprocals, was analyzed for general and specific combining ability estimates and components of genetic variation to investigate the genetic retrospect and inheritance pattern of eleven quantitative and fiber quality characters. Hirsutum cultivars included CIM-506, BH-160, NIAB-111, CIM-497, NIAB-999 and RH-510. Some of the traits like boll number, boll weight and sympodia plant-1 did not reveal the highest GCA scoring parent for seed cotton yield. The ranking order for GCAs of the parents was not maintained from F1 to F2diallel set and the ranking order of the hybrids with respect to their SCA values was also not maintainable from F1 to F2 diallel set. Thus the hybrids could not maintain their superiority (or inferiority) of their SCA values
Effects of Bikram Yoga on Body Composition, Blood Pressure, and Sleep Patterns in Adult Practitioners
Get PDFStudies have demonstrated positive results for people who practice traditional yoga, specifically in body mass index, depression, cancer, sleeping patterns, and diabetes. Most forms of traditional yoga are held in a temperate climate between 293 Kelvin (K) to 295 K; a temperature that is calming and places little stress on the body. Bikram yoga, however, is a more intense form of yoga performed in a hotter climate, typically at 314 K with 40% humidity. The purpose of this study was to determine how Bikram yoga affected blood pressure, body composition, and sleep patterns in beginner and intermediate/experienced practitioners. Participants (N=16) completed 8 weeks of sessions, ranging between 2 to 7 classes per week in a local Bikram yoga program conducted by certified instructors. All participants were assessed prior to the study and again at the end of the eight weeks. A BOD POD (an air displacement plethysmography) was used for body composition assessments, while a digital blood pressure cuff was used to assess blood pressure. In addition, participants were also surveyed on sleep parameters pre and post yoga participation. In combining all subjects, results showed there was a significant improvement (p=0.054) in faster time to fall asleep (27.66 min pre and 23.967 min post), and a trend (p=0.057) towards improved mean arterial pressure (92.20 mmHg pre and 88.33 mm Hg post). There were no differences in weight loss or percent body fat in subjects. This study indicates that there is a trend towards improved blood pressure and significant improvement in sleep parameters after 8 weeks of Bikram yoga for both intermediate/experienced and beginners, but no differences in body composition
Synthesis and Characterization of Low-Cost Epoxy-Based Erosion Resistant Nanocomposite Coating
Get PDFWe report a simple route to synthesized erosion resistant epoxy-based nanocomposite coatings. The silica nanoparticles were surfaced modified using stearic acid and then incorporated into the epoxy coating. The resulting nanocomposite coating films were characterized for erosion resistance, mechanical and thermal stability. For the application on turbine blades, conventional techniques were used. It was found that for the incorporation of nano silica into the epoxy matrix, surface modification was essential. Besides, incorporation of silica resulted in considerable improvement in the resistance to erosive wear and a life span improvement of around 36 percent was achieved. Similar trend was observed for the Shore D hardness which increases from 60 for the virgin coating to 70 for the nanocomposite coating

The Ross-Macdonald model is modified and a trapping probability function is introduced to construct a partial differential equation (PDE) system. The proof of existence and uniqueness of solution of density functions to the PDE system is given, numerical simulation results based on Gaussian distribution and exponential distribution are obtained for the solutions, and graphical representations of solutions are shown and interpreted
Inhibitory Effects of the Aerial Parts of Epimedium koreanum on TPA-Induced Inflammation and Promotion in Two-Stage Carcinogenesis in Mouse Skin
Get PDFCancer prevention by supplements offers the most cost-effective long-term health strategy. Methanol extracts from the aerial parts of Epimediumkoreanum were previously found to inhibit 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammatory ear oedema and tumour promotion by TPA in the two-stage mouse skin carcinogenesis model. Four prenyl flavonol glycosides (14) were isolated from the active fraction of this extract, and were identified. The isolated compounds showed inhibitory activity against TPA-induced ear inflammatory ear oedema. The 50% inhibitory dose (ID50) of icariin (1), epimedin A (2), epimedin B (3) and epimedin C (4) for TPA-induced inflammation ranged from 114 to 255 nmol/ear, suggesting greater potency than indomethacin (ID50: 908 nmol/ear), an anti-inflammatory drug. Thus, the epimedium herb may be useful in cancer prevention
Synbiotic Adjuvant Therapy in Atopic Dermatitis: Our Experience
Get PDFBackground: Atopic dermatitis is a disease with a lot of clinical interest because it is the point of attachment between allergic diseases and autoimmune diseases. Probiotics and synbiotics favor the expression of anti-inflammatory Th1 cytokines which produces therapeutic benefits in patients with atopic dermatitis as revealed by recent meta-analysis.Material and Method: Six patients (3 women and 3 men) suffering from moderate atopic dermatitis aged between 16 and 28 years were treated with Bifidobacterium lactis BS01, Lactobacillus rhamnosus LR05 and prebiotic fructo -oligosaccharides (2x109CFU) once daily in a period of four months added to their previously scheduled topical treatment. SCORAD index and atopic dermatitis quality of life test (QoLIAD) prior to treatment and four months after treatment were analyzed.Results: After 4 months of treatment we objectified clinical improvement by reducing the SCORAD index (average of 6 points) and better results in QoLIAD test in 5 of the 6 patients. Previously scheduled medical treatment remained unchanged and no side effect was observed in any of the patients treated.Discussion: Most of our patients treated obtained clinical improvement and in quality of life without adverse effects, this fact support the results of recent papers concluding that the use of probiotics in diary clinical practice is a safe coadyuvant and possibly effective in the treatment of atopic dermatitis
