ABSTRACT: Bovine fasciolosis is an economically important parasitic disease of cattle caused by Fasciolidaetrematodes of the genus Fasciola. The two most important species of this genus, Faciola hepatica and Faciolagigantica, are commonly known as liver flukes. The distribution of fasciolosis is worldwide, however, the distribution of Faciola hepatica, is limited to temperate areas and highlands of tropical and sub-tropical regions while Fasciolagigantica, which predominates in tropical area. The definitive hosts for Faciola hepatica are most mammals among which sheep and cattle are the most important once. The geographic distribution of trematode species is dependent on the distribution of suitable species of snails. Ethiopia has a high livestock population but productivity is low as a result of diseases, malnutrition and other management problems. Both Faciola hepatica and Faciolagigantica species of genus Faciola are found in Ethiopia and are transmitted by Lymnaea truncatula and Lymnae natalensis, respectively and various reports indicated that it is a serious problem of livestock production in Ethiopia causing considerable economic losses. Diagnosis based on clinical signs, seasonal occurrence and a previous history of fasciolosis. Fasciolosis causes a substantial economic loss which includes death, loss in carcass weight, reduction in milk yield, condemnation of affected liver, decline production and productive performances, exposure of animals to other diseases due to secondary complications.

Abstract: Pasteurella multocida subspecies multocida is the most common cause of fowl cholera, although pasteurellamultocida subspecies septica and gallicida may also causefowl cholera-like disease to some extent. However, the virulence properties of the different subspecies for various hosts have not been elucidated. The seventy and incidence of pasteurellamultocida infections may vary considerably depending on several factors associated with the host (including species and age of infected birds), the environment and the bacterial strain. No single virulence factor has been associated with the observed variation in virulence among strains. Possible virulence factors include the following: the capsule, endotoxin, outer membrane proteins, and iron binding systems, heat shock proteins, neuraminidase production and antibody cleaving enzymes.  Carrier birds seem to play a major role in the transmission of cholera.  The site of infection for pasteurellamultocida is generally believed to be the respiratory tract. The outcome of infections may range from peracute/acute infections to chronic infections. In the former type of infections, few clinical signs are observed before death and the lesions will be dominated by general septicemia lesions. In chronic forms of pasteurellamultocida infections, suppurative lesions may be widely distributed, often involving the respiratory tract, the conjunctiva and adjacent tissues of the head. Diagnosis is always dependent  the development of safe and efficient live vaccines still poses problems.

Abstract: This article describes the application of remote sensing data to monitor and analyze land use and land cover changes, natural phenomena and human activities on the environment. In this case, the information on the maps helps to determine the categories of effective land use for sustainable development. Remote sensing and GIS help to organize and control the natural resources in any part of the world, analyze the effect of anthropogenic factors on the earth's surface and its use and change. In this article, the change of the land layer of the Republic of Karakalpakstan in the last 5 years and the identified changes were compared and analyzed with the help of geoinformation technologies in the analysis of space images using the Sentinel-2 global satellite data and data visualization [1,2].

Abstract: Background: Managerial skills guidelines improve head nurses’ knowledge and practice regarding care, as well as organization performance increase. Aim: Design and validate head nurse managerial skills guidelines at Main Mansoura University Hospital. Methods: A methodological research design was used in the conduction of the present study with sample of 98 head nurses at main Mansoura University. Data was collected by utilizing managerial skills questionnaire Results: Near half of head nurses agreed that proposed guideline are importance, the first rank was about team work skills while the conflict management skills were ranked as the last skills as well as that more than half of head nurses agreed that proposed guideline were usually applicable Also, the present study indicated that the proposed guideline agreed upon its face and content validity via majority of jury experts. Conclusion: A managerial skills guideline is reliable and valid that provides some skills needed by head nurses as team work, risk taking, analytical and problem solving, decision making, communication delegation and conflict skills. Recommendations: Head nurses should be taught using real-world scenarios to develop their skills, Regulate development programs depending on key elements of managerial guideline. Design formal feedback system on head nurses progress and performance for increasing feeling of need of developing skills.

Abstract: The objective of this study is to answer two questions, the first question is, whether the soft soil always increases the seismic response of structures regardless of the frequency content of an earthquake. The second is to check if response spectrum curves will be affected by the existence of superstructures of different heights. The study was conducted on representative strips of tall buildings ranging from twenty to eighty floors. Models were calibrated based on a study of dynamic analysis using soil structure interaction done by PLAXIS software. The study tried to optimize modeling by using a close to reality models that include both nonlinear structures and soils. Contrary to current guidelines, using earthquakes with different frequency domains shows that harder soil can magnify seismic response more than soft soil. The existence of superstructures in the study changes the induced response spectrum curves in an obvious way.
