AM Mubi
Ethiopian Journal of Environmental Studies and Management , 2012,
Abstract: The study examines species density and diversity distribution in riparian landscape along 18km stretch of Mayo Kam. Total of 117 Samples quadrants of 125m2 (46), 225m2 (25), and 275m2 (46) from strata 5m (zone A), 9m (zone B), and 11m (zone C) respectively away from the Channel Bank Edge (CBA) through the Hydraulic Floodplain (HFP) and the Genetic Floodplain (GFP) were delineated and detailed survey was carried out. Data was collected on river bank morphology, altitude a.m.s.l., slope gradient, soil type, and tree species density and diversity. Result of species distribution revealed mean densities and diversities in zones A, B, and C as, 10 and 4 per 125m2, 10 and 3 per 225m2, and 23 and 5 per 275m2 respectively. Accordingly, density and diversity per 625m2 show maximum of 83 and 8 and minimum of 5 and 5 on outer convex bank and inner straight bank. Brachystigia eurycoma, Vetix doniana, Andria enermis and Diospyrus spp are the obligates of zone A. Characterizing zone B are Anogeisus leocarpus, Peninari excelsa, Crossoptyx februfuga and Nauclea latifolia species while, common species in zone C are Uapaka togoensis, Terminalia glaucoscens, and Grewia mollis. The dense and diverse pattern in the distribution within the three zones is importantly due to relative location of stratum from channel flow (variation in moisture availability), morohologic form, soil type and slope gradient. Key Words: Bank form, density, diversity, landscape, Mayo Kam, riparian, species
Knowledge, attitude and practice of nurses toward peak expiratory flow meter in primary health care centers in Kuwait
AM Hajia
Alexandria Journal of Medicine , 2011,
Abstract: Background: Peak expiratory flow meter (PEFM) is an easy to use, relatively cheap device that can be used for guiding management of bronchial asthma by the patients at home according to a preset plan by health care workers. Objective: The aim of the study is to reveal the extent of knowledge and perception of nurses about PEFM and factors affecting their knowledge. Methods: Out of the total primary health care centers in Kuwait, 50% were randomly selected. Out of 699 nurses currently working in the selected centers, 516 nurses were interviewed for this study with an overall response rate of 73.8%. Results: The results of this study showed that nurses had a relatively low total knowledge score percent of 64.7 ± 7.3%. The lowest individual mean percent score was that of procedures and steps of measuring peak expiratory flow rate (39.0 ± 24.1%). The highest percent knowledge score was that of benefits of use and content instructions for teaching patients (78.3 ± 19.5% and 78.1 ±12.0%, respectively). Sociodemographic factors did not affect the total knowledge score. Receiving training, availability of PRFM in the health center and being responsible about taking the measurements for patients proved to significantly affect the level of knowledge of nurses. Conclusion: Training nurses about use of PEFM and providing primary health care centers with the devices would plan an important role to improve knowledge of nurses and hence improve domestic health care of patients with obstructive lung diseases.
Improving Performances in the Public Sector: The Scientific Management Theory of F W Taylor and Its Implications for Library and Information Services
AM Ibrahim
Information Manager (The) , 2007,
Abstract: The need for improve performances in organization has always been a source of concern for management in both the public and the private sector. This paper sought to discuss the principle of scientific management theory as propounded by F.W. Taylor with the aim of ensuring that public services organizations adopts the principles for enhanced productivity, efficiency and the attainment of organizational objectives. The paper highlighted the principles of scientific management theory, and it explores how public service sector, notably the Library and Information Science segment in Nigeria, can benefit from its well tested principles. The main reason for the paper is the apparent inefficiency of the public sector, as observed and reported by several scholars over time. The Information Manager Vol. 7 (2) 2007: pp. 40-45
Nigerian home video movies and enhanced music involvement
AM Makhu
Creative Artist: A Journal of Theatre and Media Studies , 2010,
Abstract: The Video Film Industry in Nigeria has attracted much attention within the shores of Nigeria, Africa and beyond in Asia and in Europe. The popular acclaim trailing the industry not withstanding, there has arisen in several fora, critical assessment of the contents of the work churned out in great quantum. One such area that has elicited comment is the area of music involvement which is seen by many as significantly ignored by producers or inadequately represented. The concern of this paper is to put in proper perspective the significance of music involvement in Nigerian video films thus opening windows of opportunities for film makers and users in a bid to fostering a better appreciation of the genre.
Comments on Regulation Issues in Modern Art Practice in Nigeria
AM Diakparomre
African Research Review , 2010,
Abstract: The practice of the visual arts in post-independence Nigeria has been variedly characterized. This has been more so since 1977 when the 2nd World Black and African Festival of Arts and Culture was held in Nigeria. This epochal event is, today, said to have engendered mercantilism, a decline in standard of art products, and a laisser-faire attitude towards art practice in Nigeria. These, it is said, have singly and collectively affected the status and working conditions of the Nigerian artist. It is also said that the practice of the arts, as well as the artist, are in jeopardy, at the moment. To remedy this situation, it is suggested by some, that the practice of the arts be regulated and that a code of conduct should be instituted. These suggestions are interrogated in this paper with the aim of finding out the suitability of these prescriptions for solving the identified problems in a 21st century art environment. The interrogation identifies that resorting to regulation would amount to imprisoning creativity and lead to retrogression.
The Use of Tissue Expanders in Hypospadias Cripples and Complex Anterior Urethral Stricture: Early Experience
AM Shaaban
African Journal of Urology , 2004,
Abstract: Objective: This procedure was introduced to evaluate the use of tissue expanders in patients with complex anterior urethral strictures and hypospadias cripples where there is not enough healthy penile skin to bridge the urethral defect or to cover the neourethra. Patients and Methods: Six patients with a mean age of 23.3 years were included in this study. Four patients presented with complex hypospadias after failed multiple repairs. Three of them presented with penoscrotal meatus, residual chordee and scarred ventral penile skin. The fourth patient had multiple proximal fistulas with a scarred narrow distal urethra. The fifth patient was circumcised with a concealed penis and a congenitally short urethra. The sixth patient was referred from another institution after previous unsuccessful urethrotomies and urethroplasties. He had a curved penis, a calcified urethral plate and a proximal penile urethral meatus after first-stage Johanson procedure. The tissue expander was placed under the dorsal penile skin through a subcoronal incision. Penile skin expansion was performed gradually over 5-8 weeks. Urethroplasty was then performed using the Thiersch-Duplay technique with penile covering using the excess dorsal penile skin. Results: Expansion of the dorsal penile skin was performed successfully in all cases. There were no complications related to the use of tissue expanders except for minimal discomfort at the start of expansion. Complications related to urethroplasty included mild skin infection and temporary penoscrotal urethrocutaneous fistula (which closed spontaneously), a subcoronal fistula that required surgical closure and disruption of the glandular sutures in one case each. Conclusions: The initial good results of this technique are encouraging in patients presenting after multiple failed urethroplasties. It seems to provide an alternative to free grafts, which at present is the only solution for such cases. However, further evaluation on a larger number of patients is required. L\'utilisation des expanseurs de tissu dans le traitement de l\'hypospadias et du rétrécissement urethral antérieur complexe: Une première expérience Objectifs : Evaluer l\'utilisation des expanseurs de tissu chez les patients présentant des rétrécissements uréthraux antérieurs complexes et les hypospadias où il n\'y a pas assez de peau pénienne saine pour couvrir le défect uréthral ou pour réaliser un néo urèthre. Patients et méthodes: Six patients présentant un age moyen de 23,3 ans ont été inclus dans cette étude. Quatre patients se sont présentés avec des hypospadias complexes après échec de réparations multiples. Trois d\'entre eux ont présenté un méat péno-scrotal, une chordee résiduelle et une peau pénienne ventrale de mauvaise qualité. Le quatrième patient a eu des fistules proximales multiples avec un rétrécissement marqué de l'urètre distal. Le cinquième patient a été circoncis avec un pénis enfui et un urèthre congénitalement court. Le sixième patient a
Constructions, applications and the environment of greenhouses
AM Omer
African Journal of Biotechnology , 2009,
Abstract: A greenhouse is essentially an enclosed structure, which traps the short wavelength solar radiation and stores the long wavelength thermal radiation to create a favourable microclimate for higher productivity. The sun’s radiation incident on the greenhouse has two parts: direct radiation and an associated diffuse sky radiation. The diffuse part is not focused by the lenses and goes right through Frensel lenses onto the surface of the absorbers. This energy is absorbed and transformed into heat, which is then transported via the liquid medium in copper pipes to the water (heat) storage tanks or, if used, open fish tanks. In this way, an optimal temperature for both plant cultivation and fish production can be maintained. Stable plant growth conditions are light, temperature and air humidity. Light for the photosynthesis of plants comes from the diffuse radiation, which is without substantial fluctuations and variation throughout most of the day. The air temperature inside the greenhouse is one of the factors that have an influence on the precocity of production. The selective collector acts in a more perceptible way on extreme air temperatures inside the greenhouse. Hence, the system makes it possible to avoid the excessive deviation of the temperature inside the greenhouse and provides a favourable microclimate for the precocity of the culture. Sediment and some associated water from the sediment traps are used as organic fertiliser for the plant cultivation. The present trend in greenhouse cultivation is to extend the crop production season in order to maximise use of the equipment and increase annual productivity and profitability. However, in many Mediterranean greenhouses, such practices are limited because the improper cooling methods (mainly natural or forced ventilation) used do not provide the desired micro-climatic condition during the summer of a composite climate. Also, some of these greenhouses have been built where the meteorological conditions require some heating during the winter, particularly at night. The worst scenario is during the winter months when relatively large difference in temperature between day and night occurs. However, overheating of the greenhouse during the day is common, even in winter, requiring ventilation of the structure. Hence, several techniques have been proposed for the storage of the solar energy received by the greenhouse during the day and its use to heat the structure at night. Reviews of such techniques are presented in this article. Air or water can be used for heat transport. The circulating water is heated during the day via two processes. The water absorbs part of the infrared radiation of the solar spectrum. Since the water is transparent in the visible region, they do not compete with the plants that need it. Alternatively, the water exchanges heat with the greenhouse air through the walls. At night, if the greenhouse temperature goes down below a specified value, the water begins to circulat
Vegetation Effects on Pedogenetic Forms of Iron and Aluminium and Mineralogical Properties of Basaltic Soils in the Southern Guinea Savanna of Nigeria
AM Samndi
Bayero Journal of Pure and Applied Sciences , 2012,
Abstract: This study investigates the effects of vegetation particularly fast growing exotic species like Tectona grandis on the Newer Basalt of the Jos Plateau. In particular it determines the effects exotic tree species have on the pedogenetic forms of Fe and Al and mineralogical properties of the basaltic soils age. Soil samples were determined at the depth of 0 – 30cm and 30 – 60cm under plantation of four different ages and subjected to standard laboratory analysis. The citrate bicarbonate dithionite (CBD) extractable Fe and Al slightly decreased with aging plantation, which was ascribed to the inhibitory effects of organic matter on the crystallization of Fe and Al. Similarly the active Fe value was less than unity, which implied increased crystalline forms of Fe and Al oxides are as a result of weathering intensity. Mineralogical results indicated that the soils under the fallow and 11 year old plantation had the dominance of magnetites, while those under 21 year old plantation had mixed mineralogy, consisting of magnetites, biotites and montmorillonites. The older plantations (31 and 36 year old) were dominated by kaolinites and traces of haematites and goethites. The trend suggested an increased level of pedogenesis with aging plantations. Increase in crystalline forms of Fe and Al, kaolinites, traces of haematite and goethite concludes that Tectona grandis deteriorates soil properties over time.
