Rotation of Maize with some Leguminous Food Crops for Sustainable Production on the Vertisols of the Accra Plains of Ghana
KK Nyalemegbe, TY Osakpa
West African Journal of Applied Ecology , 2012,
Abstract: Five food legumes were grown, as cover/food crops, in rotation with maize, at the University of Ghana, Soil and Irrigation Research Centre, Kpong. The legumes were determinate cowpea (Vigna unguiculata (L.) Walper, var. soronko), indeterminate cowpea (Vigna unguiculata (L.) Walper, var. Adidome mottled), soyabean (Glycine max (L.) Merril, var. GMX 92–16-2M), bambara groundnut (Vigna subterranea (L.) Verd, var. Ada) and groundnut (Arachis hypogea L., var. goronga). The experimental treatments were: incorporated legume residues, recommended inorganic fertilizer application (100 kg N, 60 kg P O and 40 kg K SO ha-1) and no fertilization as 2 5 2 4 control. Soil samples (0-20 cm depth) were analysed for pH, organic carbon (OC) and nitrogen (N) contents before and after the experiments. Samples of the leguminous crops were also analysed for N content. The indeterminate cowpea continued growth after initial setting of pods and, therefore, had greater biomass (total dry weight – TDW) than the other leguminous crops. Its total N was relatively high in spite of lower N content. The TDWs of indeterminate cowpea, soyabean and groundnut were 2.80, 1.90 and 1.85 t ha-1, respectively; the N contents were 2.7, 4.5 and 4.8% and the total N contents were 75.6, 91.2 and 83.3 kg ha-1. Grain yields of maize were higher in the incorporated soyabean and groundnut treatments than the other leguminous crops. In the major rainy season in 2003, grain yield in the groundnut treatment was 3.3 t ha-1, compared with 3.1 and 1.1 t ha-1 in the inorganic fertilizer treatment and the control, respectively. In the minor rainy season in 2004, grain yield was 3.0 t ha-1 in the soyabean treatment, compared with 3.0 and 1.6 t ha-1 in the inorganic fertilizer and control treatments.
Composition of the Invasive Macrophyte Community in three river basins in the Okyeman Area, Southern Ghana

West African Journal of Applied Ecology , 2012,
Abstract: A survey was carried out to study the composition of the invasive aquatic macrophyte community including submerged forms, in three river basins the Okyeman area namely the Ayensu, Birim and Densu basins. Of prime interest was the presence of any one of these four species, Pistia stratiotes (water lettuce), Eichhornia crassipes (water hyacinth), Azolla species (fairy fern) and Salvinia molesta (Kariba weed), a floating water fern, which are alien to Africa. The number of invasive macrophytes encountered in the survey of the macrophytes was low with Eichhornia crassipes (water hyacinth) conspicuously missing. A concerted effort to exclude these species from our freshwater bodies is suggested as the presence of any of these four is regarded as detrimental to aquatic life, because once they become established they tend to prevent the growth of native ones.
A Check-list of Some Elements of the Vegetation in three river basins in the Okyeman Area, Southern Ghana
TY Annang
West African Journal of Applied Ecology , 2012,
Abstract: The composition of some elements of the aquatic flora was determined in three river basins namely Ayensu, Birim and Densu, in the Okyeman area in Southern Ghana. Samples of these vegetation types, namely bryophytes, podostemonads and rhodophytes, in the three river basins were taken at 16 sites as follows: 4 sampling sites from the Ayensu basin, 7 sampling sites within the Birim and 5 sites were sampled in the Densu basin. Two species of rhodophytes were identified inconclusively. However no bryophyte species and podostemonads were encountered due to stated factors. Issues concerning detailed update of these members of the aquatic flora in Ghana are discussed.

Variation in the Proximate, Energy and Mineral Compositions of Different Body Parts of Macrobrachium macrobranchion (Prawn)
E. Ekpenyong,I. O. Williams,U. U. Osakpa
Journal of Food Research (JFR) , 2013, DOI: 10.5539/jfr.v2n2p150
Abstract: The proximate and elemental compositions of various body parts of Macrobrachium macrobranchion (prawn) obtained from the Great Kwa River, a major tributary of Cross River estuary in Cross River State, Nigeria were investigated using standard methods of AOAC. Results showed that the flesh had significantly higher (p < 0.05) levels of protein, fat and moisture (22.32, 7.70 and 58.40%, respectively) than the other body parts analyzed. Equally high in protein were the head (20.11%) and appendages (19.28%), while the exoskeleton recorded the least protein content (14.02%). The flesh had the least (p < 0.05) crude fibre (0.03%) and carbohydrate (7.22%) contents, and conversely had the least energy value (187.50 kcal/g) among the body parts. Ash content was significantly higher (p < 0.05) in the exoskeleton (7.14%), the appendages (7.01%) and the head (6.05%) than in the flesh (4.30%). Individual elements were also unequally distributed among the four body parts investigated: sodium and potassium were more concentrated in the flesh (189.27 mg/100 g and 114.70 mg/100 g, respectively), while calcium and magnesium were highest in the appendages (99.02 mg/100 g and 171.40 mg/100 g, respectively). The concentration of iron was generally low among the body parts; however, it was highest (p < 0.05) in the head. The usual practice of retaining the flesh and discarding the “hard” parts (head, exoskeleton and appendages) of prawn during food preparation should be discouraged as this may promote wastage of important nutrients.
Análise da dose do laser de baixa potência em equipamentos nacionais
Fukuda, TY;Malfatti, CA;
Brazilian Journal of Physical Therapy , 2008, DOI: 10.1590/S1413-35552008000100013
Abstract: introduction: low-level laser therapy is becoming more popular and there is a growing interest in its effects, as reflected in the increased number of articles published about the subject. many therapists and researchers have used a laser dose definition based on energy density (de). however, the variety of laser equipments may lead to differences in the therapeutic results found, since the parameters supplied by these equipments vary according to the manufacturer. objective: to analyze the final energy transmitted to the tissue when applying the same de using equipment of different brazilian brands. material and methods: seven brands of brazilian equipment with different mean power (pm) were evaluated by means of simulations. de of 1j/cm2 was applied using each brand of equipment, in order to evaluate possible differences in the final energy. results: the same de applied using different brands of brazilian equipment supplied final energy that ranged from 10 to 90mj. this variation in the energy was mainly due to differences in pm. these values ranged between 5.4 and 75mw. conclusions: this variability in the final energy that is transmitted to the tissue indicates that de may not be the best parameter for describing the dose to be used. in addition to de, the final energy needs also to be stated, in order to establish the dose for obtaining the best therapeutic results.
Tradition and Art Appreciation: A Boost to Cultural Tourism in Nigeria
KO Bakare, TY Akinbileje
African Research Review , 2010,
Abstract: It is abysmal and disheartening to observe that Nigeria is depleted of parts of its cultural treasury to looters. It is delighted to deduce that these assets (tradition and art) are indispensable to our cultural pride and are potential assets to tourism, which has recently become world s gold mine . The paper examines the implications of non-challant attitudes of Nigerians toward cultural preservation which adversely perch on our cultural bearing and disposition. It suggests solutions to some upheavals been faced by cultural tourism in Nigeria. It further unveils the deception and antics used by foreigners to dispossess us of our cultural heritage, which is consequently repackaged and sold back to us at extortionate prices. This study endeavors to document the inventory of some museums in Nigeria. In essence, the earlier Nigerians realize this, the better for us to start to reap the unflinching prospects inherent in our cultural heritage and endowment. The paper recommends that there is need for individual citizens to develop profound interest in Nigeria s cultural heritage for development of tourism industry via cultural assets, so as to generate substantial foreign exchange earnings, accelerate rural urban development, generate employment and promote local cultural exchange for national unity and identity.
Art as a Tool in the Built Environment
J Igbaro, TY Akinbileje
African Research Review , 2010,
Abstract: Man’s interaction with the environment dates back to creation. The interaction of man with its environment has been crucial to the continuous existence of man in relation to solving the fundamental or basic needs of food, shelter and clothing. This has been woven into a web of different cultural environment. This type of cultural environment includes palaces, shrines, markets, malevolent forest and places of social interaction. Man retreated into the protective warmth of cave while the environment threatened his survival (wild animals and weather condition). It was at this period that attempt was made at artistic creation. From this natural habitat developed the more comfortable houses that have been built up till today. Basically, traditional African society operates in environments that advance healthy living, moral values and steady communal growth. They built many houses that are architectural master pieces and decorated them aesthetically without architects and professional designers. The cities and villages were set up according to the dictates of the environment within which they lived without town planners, yet, some of them can be likened to streets in Amsterdam (Denyer 1978). The absence of the architects and town planners were adequately catered for by artists (carvers, moulders, painters and other craftsmen). Today, many of our towns and cities are reflections of great wealth without commensurate aesthetic value, while some others portray signs of poverty of ideas and skilled men because art has been neglected. The thrust of this paper is to access the invaluable role that art plays in nationbuilding through the built environment that we can call our own. It also emphasized the significance of the role of professional artists in the support of a reliable and conducive environment, which was very prominent among the traditional people.

Abstract: ical course and management of postoperative methicillin-resistant Staphylococcus aureus keratitis in immunocompromised patients: two case reports Case report (2179) Total Article Views Authors: Chou TY, Prabhu SP Published Date December 2011 Volume 2011:5 Pages 1789 - 1793 DOI: http://dx.doi.org/10.2147/OPTH.S23201 Timothy Y Chou1, Sujata P Prabhu2 1Department of Ophthalmology, State University of New York Stony Brook, Stony Brook, NY, 2Shiley Eye Center, University of California San Diego, La Jolla, CA, USA Abstract: We describe the clinical course and successful treatment of two cases of methicillin-resistant Staphylococcus aureus (MRSA) keratitis. In case 1, MRSA keratitis occurred 5 days after cataract extraction, associated with endophthalmitis; in case 2, diagnosis was made 19 months after penetrating keratoplasty. Treatment in both cases consisted of topical fortified vancomycin and fortified bacitracin. A third topical antibiotic, polymyxin B-trimethoprim, was added to the therapeutic regimen in case 2, one month into the treatment. Oral doxycycline was prescribed to reduce collagenase activity and treat blepharitis. Mupirocin nasal ointment and skin antiseptics were used to decrease and eliminate potential MRSA colonization. Topical prednisolone acetate 1% was applied conservatively to mitigate inflammation in both cases. In case 2, topical cyclosporine A was also used for similar purposes. Keratitis may have worsened while on these immune-modulating drops, especially in case 2, and eradication of infection may have been slowed. Eventually both patients achieved full resolution of infection. Duration of keratitis was 3 and 1.5 months, respectively. Polyantimicrobial therapy is effective in eradicating MRSA-related postoperative keratitis. Topical fortified vancomycin and fortified bacitracin were used in both cases, with a third topical antibiotic, polymyxin B-trimethoprim, also required in case 2. Oral doxycycline, nasal mupirocin, and antiseptic soap may be useful adjuncts in management. Treatment time to achieve full resolution may be prolonged relative to other types of bacterial keratitis. Alterations in immune status may have lengthened the time of treatment. Our two patients were immune compromised and were also susceptible to endophthalmitis. It is possible that topical immune-modulating drops such as prednisolone acetate may potentiate MRSA infection, and if used, should be only done so with great caution.
