    The study conducted from 2006 to 2012 with an interval of every two years in the ecoreef area of ā€‹ā€‹ Manado Tua island found 2,936 individual reef fishes of 181 species that include into 32 families. Species composition value of the 10 dominant species of reef fishes was 55.48% of the total species. The highest number of species was Plotosus lineatus with schooling behavior which only discovered in 2010 at a depth of 3 meters. Ecoreef area of Manado Tua island, when analyzed from the abundance and biomass of reef fishes exhibited a succession of reef fish that have been stable, with peak abundance and higher biomass in 2008 and 2010. Reef fish found in ecoreef seemed to start a new living and become a new habitat for them. These were indicated by the highest biomass during the previous year but the number of individuals and spesies were decline. There was no change in the structure of reef fish communities in the ecoreef area of Manado Tua Island, which characterized by non significant different ecological index between the years. Cluster analyses grouped reef fish species into 2 groups i.e., the group of 2006 and the group of 2008, 2010, and 2012. Early survey in 2006 showed lower abundance of reef fish species for allegedly associated with low ecoreef organisms

    This cross-sectional descriptive study explored knowledge and perceptions of maternal health and awareness of health services among women and men of reproductive age in rural communities in Zaria, Kaduna state Nigeria. Among the sample of 647 respondents, 72.6% of men and only 35.9% of women had received formal education. Knowledge of maternal health was very low. In a three point scale (poor, fair, good), only 3.1% of men and 1.2% of women had good knowledge of maternal health. The association between the respondentsā€Ÿ educational level and their maternal health knowledge was statistically significant. Socio-economic barriers were identified as limiting this populationā€Ÿs optimal utilization of maternal health services. Furthermore, some respondentsā€Ÿ perceived available health care services to be of low quality. In order to improve reproductive health in rural northern Nigeria, it is imperative to improve access to formal education, increase knowledge about maternal health care, and improve the quality of care offered in health care facilities (Afr. J. Reprod. Health 2010; 14[3]: 71-76).Key words: Maternal health, reproductive health, knowledge, perception, health care utilization, rural, northern Nigeria

    Preliminary Study on the Kinetics and Mechanism of the Oxidation of Naphthol Green B by Dichromate Ion in Aqueous Hydrochloric Acid Medium

    Get PDF
    - The kinetics of the oxidation of naphthol green B (NGB3-) by Cr2O7 2- has been studied in aqueous hydrochloric acid medium at an ionic strength, I = 0.50 mol dm-3 (NaCl), H+ =1.0 10-4 mol dm-3 (HCl) and T = 25 1C. The redox reaction displayed a stoichiometry of 1:1 and obeys the rate law: -dNGB3-/dt = k2NGB3-]Cr2O7 2- . The second order rate constant increases with increase in acid concentration and in the ionic strength of reaction medium. The rates of reaction displayed a positive salt effect. Addition of acrylonitrile to a partially reacted mixture in the presence of excess methanol did not lead to gel formation. Added cations and anions inhibited the naphthol green B - Cr2O7 2- reaction. Results of the Michaelis ā€“ Menten plot gave no evidence of intermediate complex formation during the course of the reaction. Based on the results obtained, the reaction is believed to proceed through the outersphere mechanistic pathway

    Mangrove species' association and distribution patterns in Tumpat, Kelantan Delta, east coast of peninsular Malaysia

    Get PDF
    We studied mangrove vegetation at Tumpat to estimate different tree structural parameters (e.g., stem density and basal area) at selected sites (PCQ-Method). There were 5 dominant taxa in the vegetation, i.e., Sonneratia caseolaris, Nypa fruticans, Avicennia alba, Rhizophora mucronata, and Bruguiera gymnorrhiza in order of importance. Total tree density varied between 79 and 132 stems 0.1ha-1, and basal area from 0.14 to 4.9m2 0.1ha-1. Based on species composition and stem density, the mangrove sites could be separated into two groups (Bray-Curtis similarity: 60%). While Group-1 (sites G9, J5, K4, N6 and O4), dominated by S. caseolaris and N. fruticans, was distributed throughout the forest, Group-2 (sites C6 and G6), represented largely by A. alba, is present close to the bay-mangrove boundary. Elevation measurements indicate that Group-1 species occupied lowlying to elevated grounds (0.87-2.23m above the mean sea level) with a (mean) salinity between 0.38 and 14.6psu, whereas Group-2 occurred preferentially at low to medium elevations (0.86-1.29m) and high salinity (14.6psu). Discrete mangrove associations (=groupings) were discerned, wherein the distribution of species is governed by factors such as proximity of land or sea, freshwater input and elevation

    A concentric design of a bypass magnetorheological fluid damper with serpentine flux valve

    Get PDF
    This work presents a new concentric design structure of a bypass magnetorheological (MR) damper with a serpentine flux valve type. In this design, the serpentine valve is installed not in the middle of the piston but on the bypass channel of the damper. However, to make it less bulky, the location of the valve installation is chosen to be in line with the cylinder axis, which is different from the common configuration of the bypass damper. With the proposed design concept, the performance flexibility of the bypass configuration and the compactness of the piston valve configuration can be accomplished. In this study, these benefits were demonstrated by firstly deriving an analytical model of the proposed MR damper focusing on the bypass concentric valve structure, which is vital in determining the damping force characteristics. The prototype of MR damper was also fabricated and characterized using the dynamic test machine. The simulation results show that the damping force could be adjusted from 20 N in the off-state to around 600 N in the on-state with 0.3 A of excitation current. In the experiments, during low piston velocity measurement, the on-state results from the simulation were generally in good agreement with the experimental results. However, with the increase in piston velocity, the deviation between the simulation and the experiment gets higher. The deviations are most probably due to seal frictions that were not accounted for in the model. The seal friction is probably dominant as the seals in the prototype need to be prepared for handling higher fluid pressure. As a result, the frictions are quite prevalent and significantly affect the measured off-state damping forces as well, where it was recorded ten times higher than the predicted values from the model. Nevertheless, although there were deviations, the dynamic range of the concentric bypass structure is still 1.5 times higher than the conventional structure and the new structure can be potentially explored more to achieve an improved MR damper design

    Evaluation of neutrophil gelatinase associated lipocalin (NGAL) in type 2 diabetic patients with diabetic nephropathy

    Get PDF
    Diabetic nephropathy (DN) is a devastating chronic microvascular complication that represents the major cause of end-stage renal failure leading to the development and progression of diabetic syndrome. Aim: The aim of this study was to evaluate serum neutrophil gelatinase associated lipocalin (NGAL) in type 2 DM with diabetic nephropathy. Methods: Eighty (80) type 2 diabetic patients with DN and apparently healthy controls were respectively recruited. Blood samples were collected and tested for serum NGAL, creatinine, albumin, fasting plasma glucose and HbA1c. Creatinine and albumin were analyzed using Abbot autoanalyser, HbA1c was analyzed using fine care system and serum NGAL using the ELISA method. Estimated GFR (eGFR) was calculated using the modification of diet in renal disease (MDRD) formula. Statistical analysis was performed using statistical package for social science (SPSS) software version 20.0. Student t-test, one way analysis of variance (ANOVA) and Pearsonā€™s correlation were used for comparisons and correlation of data respectively with level of significance set <0.05. Result: The mean values of the serum NGAL, FPG, HbA1c, BMI and eGFR in both DN group and control group were found to be 3.72Ā±2.62 vs 1.08Ā±0.78Ī¼g/ml, 7.06 Ā±3.46 vs 4.08Ā± 0.39mmo/l, 6.73Ā±1.08 vs 4.71 Ā±0.39%, 27.33Ā±5.29 vs 25.08Ā±3.65ml/min/1.73m2 and 76.57 Ā±11.20 vs 118.23 Ā±12.11ml/min/1.73m2 respectively. The study found a high and significant difference in the mean values of the DN group compared to the control group. A positive and significant relationship was observed between serum NGAL and eGFR and duration of diagnosis of diabetes mellitus. Conclusion: Serum NGAL could therefore be used as a biomarker to diagnose DN even earlier to incipient nephropathy, NGAL, Diabetes nephropathy, eGFR, Microalbuminuria, Glycated haemoglobin

    Lower Limb Amputation at the 34 Military Hospital in Freetown, Sierra Leone: Causes and Indications.

    Get PDF
    The global prevalence of diabetes mellitus is increasing substantially. This overall increment leads to the growth in the number of individuals with diabetic complications including lower limb amputation.Ā In low-income countries like Sierra Leone, lack of access to adequate health care, poverty and social stigma attached to ā€œamputationā€ all prevent people from seeking early medical treatment for diabetic foot.The purpose of this study was to document the causes and indications of lower limb amputations and to make appropriate recommendations to the health sector of Sierra Leone.This retrospective study was conducted at 34 Military Hospital, one of the major referral hospitals in Freetown, between January 2011 and December 2014. A team of medical staff was trained to extract data. The operating theatre and ward case records were searched for information (age, gender, cause and indication for amputation) of all the patients who underwent amputation during this period. The findings were statistically documented in tables.Twenty-seven patients (24 males and 3 females) were involved in the study. The age distribution was 15-65 years (Mean 43). Majority (77.7%) of the patients presented with gangrenous and infected diabetic feet, 18.5 % was due to Road Traffic Accident and 3.8% due to complication of HIV infection. The commonest level was transtibial amputation 85% and 67% was right sided. Hospital stay was 20-50 days (average 35). There was no postoperative mortality.As most amputations were done for diabetic feet, there is need for diabetes sensitization and prevention campaigns for the general public and improvement of diabetic care for individual patients including proper glycemic control and risk factors prevention. Increased funding is required by the health sector of Sierra Leone to implement these measures. Prevention of road traffic accidents by training/educating the drivers should also be considered by Sierra Leone Road Transport Authority.
