Preliminary investigation on growth responses of Cyprinus carpio L. fed on locally formulated artificial diets

The growth rate and feed conversion ratios of the common carp, Cyprinus carpio were measured for five test diets in 14-day replicate laboratory studies. The young carp were fed with artificial test diets with crude protein contents ranging from 14.50 to 21.42 per cent. Within this range of feed characteristic optimum growth rates were obtained with diets containing 20.25 and 21.42 per cent crude protein. The study of the effect of varying ration levels showed that growth rates increased with increases of ration size, but the food conversion efficiency and protein efficiency ratios decreased markedly as ration size was increase

An evaluation of the trophic status of the Shen Reservoir by an analysis of phytoplankton composition and water characteristics

In an effort to evaluate the production potential of an artificial impoundment, the phytoplankton of the Shen reservoir was sampled from November 1981 to June 1982 at three stations during three periods of distinct seasonal hydrographic characteristics. The samples were subsampled and quantified. Most of the phytoplankton were identified to the species level. There were in all 53 species comprising Chlorophyceae contributing 36.70% with species of Volvox, Pediastrum, Closterium, Staurodesmus and Ankistrodesmus as dominant species in this group. The Cyanophyceae contributed 30.00% with species of Microcystis, Nostoc , and Oscillatoria as the dominant species. An analysis of temporal and spatial changes in composition and abundance of the various groups showed that these were influenced by water temperature, sampling period and station. Based on the trophic status of the most abundant species, the composition of the phytoplankton is indicative of a tropical reservoir with a moderate productivity for fish cultur

Study on the biomass yield of Duckweed (Lemna minor) (L.) in hydroponic cultures containing different concentrations of aquaeous extract of chicken manure

The biomass yields of duck week (Lemna minor(L) was monitored in hydroponic media prepared by variously extracting 0.50, 1.00 and 2.00g of dried chicken manure per liter of city water (tap water) supply. The culture media consisting of aqueous extract of the various manure treatments were made up to 12 liters in all cases with tap water as control. Plastic baths of 25 liters capacity with 0.71 super(m2) surface area were used as culture facility. Each bath was stocked at a density of 30g super(m-2) with fresh weed samples (i.e 21.30g/bath). Maximum yields were obtained at all treatment levels and control on day 3 and based on the highest yield of 0.37gm super(-2)d super(-1) (dry matter) obtained at 1.00gL manure treatment which was however not significantly higher (P>0.05) than the 0.36gm super(-2)d super(-1) (dry matter) at 0.05gl super(-1) media manure content, an average manure level of 0.75l super(-1) was selected and used to determine the operational plant density. Thus fresh weights of 30 to 300gm super(-2) was grown in triplicate at 30g intervals for a period of 3 days. A regression equation of Y=2.6720+0.0021x with a corresponding maximum density or operational plant density of 266gm super(-2) and yield of 0.98gm super(-2), d super(-1) (dry matter) were obtained. Further growth trials were carried out at the operational density and manure levels of 0.50, 0.75, 1.00, 1.25, 1.50, 1.75 and 2.00gl super(-1) media manure concentration giving a significantly higher yield (P<0.05) of 17gm super(-2), d super(-1) (dry matter). This yield was however doubled to between 2.21 and 2.24gm super(-2) d super(-1) (equivalent to 7.96 to 8.06mt.ha-1, Yr-1 dry matter on extrapolation) if 25% and 75% respectively of the total weed cover were harvested daily within the experimental period. The role of some dissolved plant nutrients (DPN) were also discusse

Intra-abdominal hypertension and abdominal compartment syndrome in pancreatitis, paediatrics, and trauma

Intra-abdominal hypertension (IAH) is an important contributor to early organ dysfunction in trauma and sepsis. However, relatively little is known about the impact of intra-abdominal pressure (IAP) in general internal medicine, pregnant patients, and those with obesity or burns. The aim of this paper is to review the pathophysiologic implications and treatment options for IAH in these specific situations. A MEDLINE and PubMed search was performed and the resulting body-of-evidence included in the current review on the basis of relevance and scientific merit. There is increasing awareness of the role of IAH in different clinical situations. Specifically, IAH will develop in most (if not all) severely burned patients, and may contribute to early mortality. One should avoid over-resuscitation of these patients with large volumes of fluids, especially crystalloids. Acute elevations in IAP have similar effects in obese patients compared to non-obese patients, but the threshold IAP associated with organ dysfunction may be higher. Chronic elevations in IAP may, in part, be responsible for the pathogenesis of obesity-related co-morbid conditions such as hypertension, pseudotumor cerebri, pulmonary dysfunction, gastroesophageal reflux disease, and abdominal wall hernias. At the bedside, measuring IAP and considering IAH in all critical maternal conditions is essential, especially in preeclampsia/eclampsia where some have hypothesized that IAH may have an additional role. IAH in pregnancy must take into account the precautions for aorto-caval compression and has been associated with ovarian hyperstimulation syndrome. Recently, IAP has been associated with the cardiorenal dilemma and hepatorenal syndrome, and this has led to the recognition of the polycompartment syndrome. In conclusion, IAH and ACS have been associated with several patient populations beyond the classical ICU, surgical, and trauma patients. In all at risk conditions the focus should be on the early recognition of IAH and prevention of ACS. Patients at risk for IAH should be identified early through measurements of IAP. Appropriate actions should be taken when IAP increases above 15 mm Hg, especially if pressures reach above 20 mm Hg with new onset organ failure. Although non-operative measures come first, surgical decompression must not be delayed if these fail. Percutaneous drainage of ascites is a simple and potentially effective tool to reduce IAP if organ dysfunction develops, especially in burn patients. Escharotomy may also dramatically reduce IAP in the case of abdominal burns

Antimicrobial activities of Carica papaya leaf against diarrhoea causing agents

The advent of science to the search for antibiotics principally depends on medicinal plants as raw materials. This present study evaluated the antimicrobial effect of Carica papaya leaf extracts against bacterial and fungal agents that causes diarrhoea. Fresh tender roots and leaves of this plant was collected, air-dried, powdered and percolated in n-hexane, methanol and aqueous solvents. The antimicrobial activities of the extract against test organisms were tested by using agar well diffusion assay and the MIC, MBC and MFC values were determined by agar dilution assay. The results revealed that the crude methanol and aqueous extracts of Carica papaya had no anti-fungal activity, but have antibacterial activity. N.hexane extract of C. papaya had most activity than other solvents with MIC ranged from 25 mg/ml to 50 mg/ml and MBC ranged from 50 mg/ml to 100 mg/ml.These results suggest that paw paw leaf extract is recommended as a diarrhoea disease remedy

Multilateral organizations and global inequality: A focus on IMF, World Bank and World Trade Organizations

The paper examines issues relating to multilateral organizations, taking a particular look at the three multilateral organizations viz IMF, World Bank and WTO. It establishes that institutional and structural variables in the multilateral organizations are skewed in favour of the developed countries and this tends to entrench their hegemony in the global scene. This has crystallized in global inequality. More so, the analysis which relies on the theory of political realism with dependency theory as a complementary theory explores the power play and dominance of interests in global affairs as a defining characteristic of relations at the global level. Again, the paper establishes that a dialectical relationship exists between development in the developed North and underdevelopment in the developing South and that the multilateral organizations are veritable instruments for perpetuating the hegemony of the developed countries, which ensures the continuation of global inequality. The paper therefore puts forward a range of recommendations that could help the developing countries in their quest for development and by so doing bridge the inequality gap.Keywords: Multilateral, Organizations, Global, Inequality, Underdevelopment, Developmen

Validation of the Ejike-Ijeh equations for the estimation of body fat percentage: A random cross-sectional study in adult Nigerians

The Ejike-Ijeh equations for the estimation of body fat percentage makes it possible for the body fat content of individuals and populations to be determined without the use of costly equipment. However, because the equations were derived using data from a young-adult (18-29 years old) Nigerian population, it is important to validate the equations in a wider spectrum of adults. This study is an attempt at such validation. A total of 365 adult Nigerians aged 18 to 80 years (52.9% females) participated in this random cross-sectional study. Standard internationally accepted protocols were followed for all determinations and calculations. Appropriate statistical tools were used to analyse the data generated. The mean age of the subjects was 44±16 years. The differences between the mean ages of both sexes was not statistically significant (P&gt;0.05). Using BMI as a diagnostic, obesity was found in 12.3% of the population (17.1% in females and 7.0% in males). On the other hand, using percent fat mass (PFM), 16.4% (25.4% females and 6.4% males) were found to be obese. Measured PFM correlated positively and significantly (r=+0.635; P&lt;0.001) with the PFM-II in the general population. The correlations were stronger in males (r=+0.736) compared to females (r=+0.563). The Ejike-Ijeh equations appear valid for use in adult Nigerians.Keywords: Body fat, obesity, prediction equations, validatio

The Millennium Development Goals (MDGs) and the Problem of Policy Implementation in Nigeria

Nigeria is one United Nations member state that is increasingly working on achieving the Millennium Development Goals (MDGs) which took off at the turn of this century. The MDGs are eight goals and targets to be attained within 2015. Giving the available time, it is obvious that it is a major challenge to Nigeria because of its requirements for actualization in the country. Among the requirements is ensuring effective policy implementation. However, poor policy implementation is believed by some analysts to be the bane of development in Nigeria. The paper therefore, seeks to highlight the need for proper and effective policy implementation while identifying some impediments to be tackled if Nigeria is to ensure that policies, particularly those relating to the MDGs, are effectively and timely implemented. These impediments include, among others: corruption, badleadership, political instability, slow public service structures, ethnicity etc. The paper posits some sustainable development measures for Nigeria, such as effective use of political will, eschewing social vices (like ethnicity, favouritism, nepotism and mediocrity), continuity of policies between governments, eradication of corruption etc.Keywords: Policy, Implementation, Millennium Development Goals, NigeriaInternational Journal of Development and Management Review (INJODEMAR) Vol. 7 June, 201

Morale, Productivity and Sustainable Industrial Development in Nigeria

This paper is an analytical discourse on the interface and relationship between morale and productivity and how these have impactful influence on sustainable industrial development in Nigeria. Nigeria is a developing economy that direly needs a strong root and drive for productivity and economic development. This may not be feasible except if the drivers of the economy, particularly the human factor in the production process are not appropriately motivated to energize their morale. This paper that dwelt more on library and secondary sources of materials identified that morale and productivity, though related to each other in many facets, are at the lowest ebbs in Nigeria to essentially drive sustainable industrial development akin to competitive global integrated market economy. It also observed, among others, that certain government truncated policies and poor economic environment within which the human element as factor of production do their work challenge the morale of the operators of the economy. It therefore, recommended, among others, that government policies and work environment should be employees friendly in order to adequately energize them for global practices and to ensure the steady forward movement and progression towards sustainable industrial development in Nigeria.
