Abstract: Background: Low back pain is a real public health problem. Lots of studies have been done about it, but not in midwives group. The latter seem to be exposed to low back pain due to morphological, physical and psycho-social factors. We therefore study the place of these factors in the occurrence of low back pain in midwives. Method: Prospective, cross-sectional and analytical study, it is done with 102 midwives of university hospitals in Benin. They were interviewed and examined. An eventual link with their history of low back pain, for at least 3 months during the last 12 months before the study, was checked to their morphological aspects (spinal curvatures, BMI), physical examinations data (strength and muscular flexibility) and psycho-social factors (relationship with colleagues and either, stress, ...). The effect of these factors was assessed using relative risk (RR) with a 95% confidence interval. Results: Different morpho-physical and psychosocial disturbances were observed in midwives. 81% had a history of low back pain. The latter have a statistically significant relationship with the different factors studied. These were mostly exposure factors, but poor midwife relationship with their hierarchical superiors was a protective factor (RR = 0.69 and p = 0.0106). Discussion-Conclusion: In Benin, health workers and especially midwives are very exposed to low back pain. The latter are often associated with different morphological, physical and psycho-social disturbances. The knowledge of those parameters is interesting to reduce this high prevalence of low back pain in midwives.

Abstract: Satisfaction of patients is an important dimension of the hospital management and the evaluation of the quality of care and services offered to patients. Objective: To estimate the degree of satisfaction of patients admitted in Physical Medicine and Rehabilitation Department in the National Hospital and University Center (CNHU-HKM) in Cotonou. Method: Cross-sectional study with descriptive and analytical aim. It was led from June 15th to October 15th 2013, on 158 patients or guides of children or not communicating patients having ambulatory care in the Department of Physical Medicine and Rehabilitation and who agree to participate to the study. The level of global satisfaction of the subjects was estimated with a digital scale from 0 to 10. It was secondarily transformed into a discreet qualitative variable. Result: Rate of participation was 63.2%. Patients had deficiencies of rheumatilogical origine (41.1%), neurological (27.2%), traumatological (24.1%). Their pathologies were evolving since 1 month to 10 years. It was about their first attendance of the Rehabilitation Department of CNHU-HKM in 72.2%. Patients’ degree of satisfaction was good for the deadliness of expectation, reception (80%), cleanliness of the building, respect of patients’ intimacy. Global satisfaction of patients was good in 72%. It was influenced by the deadline of evolution of the pathologies. Discussion-Conclusion: The level of satisfaction of patients admitted in the Rehabilitation Department in CNHU-HKM was acceptable. However, they are parameters that remain to be improved.
Geochemical Characterization of Novokrivoyrog Metavolcanics: Tectonic Implications and Relationship with the Early Proterozoic Banded Iron Formation (BIF) of Krivoy Rog in Ukraine  [PDF]

Open Journal of Geology (OJG) , 2012, DOI: 10.4236/ojg.2012.23013
Abstract: The geochemical characterization of Novokrivoyrog metavolcanics (2.2 Ga) and Krivoy Rog iron ores (1.8 Ga) in Ukraine represent an important tool for the understanding of their genesis and tectono-magmatic evolution. The petrological classification of the metavolcanics on SiO2/(Zr-TiO2) and (Zr-TiO2)/(Nb/Y) Harker-type diagrams shows similarities to subalkaline andesitic basalts. An additional classification of the basalts on TAS (Na2O + K2O/SiO2) and AFM (FeO-MgO-Na2O + K2O) diagrams exhibits a variable magmatic character from calc-alkaline to tholeiitic. The distribution of High Field Strength Elements, (HSFE: Ti, Zr, Y, Hf, Nb), V, Cr, and Rare Earth Elements (REE) in most of the rocks is close to calc-alkaline basalts (CAB) and can be compared to Precambrian mid-ocean ridge basalts (MORB) where high thermal (>250°C) basaltic alteration is intensive under pH conditions between 2 and 4. These contributed to the deposition of the Krivoy Rog BIFs. Indeed REE distribution patterns of the BIFs suggest that they can be subdivided into shales and shaly BIFs (rich in LREEs since their detrital and clastic inputs are much higher) with (La/Yb)N > 1 as indication of clastic inputs; chert and cherty BIFs showing positive Eu anomaly with (La/Yb)N < 1 are similar to REE patterns of mixed hydrothermal fluids and seawater; alkaline altered BIFs whose (La/Yb)N ratio is >1 emphasizes post-depositional effects related to the enrichment of light REEs over heavy REEs with a positive Eu anomaly. The distribution of REE patterns of Krivoy Rog BIFs can finally be compared to Precambrian iron formations of mixed submarine hydrothermal fluids and seawater origin which correspond to the MORB signature of the Novokrivoyrog metavolcanics.

Abstract:

Sabga-Bamessing is a part of the Bamenda Mountains, an extinct volcanic center of the West Cameroon Highlands along the Cameroon Volcanic Line (CVL). The pristine volcanic rocks of the Sabga area are alkali mafic to felsic (basanites, phonolites, trachytes and rhyolites). Some weathered sections of a heterolithologic debris flow with a suppositious primary chemistry of the original volcanic rocks prior to weathering have shown significant calcium carbonate enrichment. CaO and LOI values of up 61.31% and 41.72% respectively show corresponding enrichment of 16.54 and 10.88, when compared with average fresh volcanic rocks. Na+ normalized molar ratios computed from the chemistry of springs and rivers show carbonate dissolution signature which is contrary to silicate dissolution expected in acid volcanic rocks. Saturation indices (SI) calculated with PHREEQC reveal that brackish to saline springs are supersaturated with Calcite (CaCO3), Aragonite (CaCO3), Dolomite (CaMg(CO3)2 and Hydroxyl apatite (Ca5(PO4)3OH). Recharging contributions to spring water chemistry deviate from those produced by rock weathering, precipitation and evaporation/crystallization. An enrichment process

Abstract: The sedimentology and geochemistry (major and trace element compositions) of lignite and argillite (carbonaceous shale and claystone) sequences in a Basin in Bali Nyonga, west of the Bamenda Mountain have been investigated to determine their sequences and the prevailing environmentalconditions which control their formation. Ten representative samples were obtained fromtrenches, pits, and river and stream valleys in the study area. These samples and their ashes were subsequently examined using X-ray fluorescence spectrometry (XRF), inductively coupled plasma spectrometry (ICP), and X-ray diffraction analysis (XRD). The geochemical results revealed that thelithophile, chalcophile and siderophile elements were dominantly epigenetic in origin, mainlyfrom detrital sources supported by high silica and alumina concentrations in all the samples. The mineral phases identified were quartz, kaolinite, illite, pyrite, hematite, and minor phases of feldspars,pseudorutile. The relatively high silica (54.10 wt%) and alumina contents (27.77 wt%) in thesesamples can be explained by high detrital input during peat formation. The low contents of MgO and CaO in the analysed samples agree very much with the continental setting of the peat formating basin. A clayey microband derived from alkaline volcanic ashes was identified in the lignite and the dominant composition of these clayey microbands was mixed-layer clay minerals of illite and kaolinte, which were interlayered with organic bands. The modes of occurrence of ash bands indicated that the volcanic activities were characterized by multiple eruptions, short time intervaland small scale for each eruption during peat accumulation. The ratios of redox-sensitive traceelement (V/Cr versus Ni/Co and V/V + Ni versus Ni/Co), Sr/Ba, and major oxides ratio (CaO + MgO + Fe2O

Abstract:


Metabolic Syndrome (MS) has reached a pandemic proportion and has an impact on the incidence and severity of cardiovascular pathologies. This study was conducted to evaluate the effect of different processed food commonly consumed in Maroua (Far North Region, Cameroon) on the Glycemic Index (GI). To ameliorate the follow up of MS and population’s nutrition education, a survey was conducted among 200 families. The ten most consumed meals were selected after a food survey among 200 families. The meals were mostly made of a vegetable soup associated to a high carbohydrate staple. Vegetables and cereals were processed according to the food survey results. Then, a food tolerance test was performed on 30 male volunteers living in the same region. Among them, 12 were selected with an average age of 28.25 and a mean BMI of 19.63. They were studied on separate occasions in the morning after an overnight fast. After fasting, blood glucose was taken before and (15, 30, 45, 60, 90 and 120 minutes) after eating a test meal compared to sucrose and glucose solution (33.33%) used as reference. Glycemic response curves were used to calculate the gi of each meal. Results show that GI of the tested meals varied significantly (p < 0.05) between 20 and 79. Red millet porridge with kelenkelen-beans (Cochorus oletorius-Vigna unguiculata) sauce and red millet porridge with kelenkelen-peanut (Cochorus oletorius-Arachis hypogea) sauce exhibited the lowest GI. The highest GI was observed in corn porridge associated with fresh okra (Hibuscus esculentus) or with tasba (Cassia tora)-okra-beans sauce.

GNSS-R: Operational Applications

Physics , 2003,
Abstract: This paper provides an overview of operational applications of GNSS-R, and describes Oceanpal, an inexpensive, all-weather, passive instrument for remote sensing of the ocean and other water surfaces. This instrument is based on the use of reflected signals emitted from GNSS, and it holds great potential for future applications thanks to the growing, long term GNSS infrastructure. The instrument exploits the fact that, at any given moment, several GNSS emitters are simultaneously in view, providing separated multiple scattering points with different geometries. Reflected signals are affected by surface roughness and motion (i.e., sea state, orbital motion, and currents), mean surface height and dielectric properties (i.e., salinity and pollution). Oceanpal is envisioned as an accurate, "dry" tide gauge and surface roughness monitoring system, and as an important element of a future distributed ocean remote sensing network concept. We also report some results from the Starlab Coastpal campaign, focusing on ground GNSS-R applications.
