This research was conducted at the Fisheries Technology Laboratorium Department of Fisheries and Marine Sciences, Gorontalo State University, at the Mey 2018 for three months in a month. Fish has a high nutritional value and is a major food source in many countries. Lipid fish has a high content of polyunsaturated acids (PUFA), especially eicosapentaenoic acid (EPA;20:5n-3) and docosahexenoate acid (DHA; 22: 6n-3). This study aims to the impact effect of temperature and storage time of the fatty acid snapper fillet (Lutjanus sp) and damage caused by the storage process. The sample selection stage is Snapper (Lutjanus sp) fresh weeds, and the meat is released by gills, bones, then washed and rinsed with ice water to remove blood and other debris. Contineus does the cleavage from head to tail without causing his back to be disturbed. Filleting is done by slicing the meat ribs longitudinally to produce boneless meat. Stored at temperatures of 0, 10, 20, 30 and 40°C for 45 days. The results of fatty acid analysis snapper fillet (Lutjanus sp) has a saturated fatty acid lauric acid, acid tridecanoic, myristate acid, pentadecanoic acid, palmitic acid, stearic acid, heneicosanoic acid, behenic acid, lignoceric acid, acid and acid heptadecanoate arachidic. Monounsaturated fatty acids oleic acid, nervonic acid, palmitoleic acid, acid and acid erucat eicosanoic, while polyunsaturated fatty acids eicosatetraenoate acid, dokosadinoat acid, eicosapentaenoic acid, eikosatrioanat acid, arachidonic acid and linolenic acid are susceptible to oxidative damage. Increased primary peroxide snapper fillet (Lutjanus sp) the higher the storage temperature increases from 0°C to 40°C. TBA value increases from 0° to 40°C with increased storage time of one day to 45 days storage time.

Climate change and its impact on water resources are one of the most important issues affecting world agriculture at the beginning of the twenty-first century. The last four decades have witnessed extensive research concerning climatic variability and trends of climatic parameters in different regions and for the different time scale. Climatic water supply, as well as demand, was changed in different regions of the world affect the food and nutritional security of the region. Crop water requirement was also affected by the variation of meteorological parameters under the conditions of climate change. The present study was undertaken to evaluate tehsil-wise weekly water surplus/deficit availability during the rainy season (June to October) in the Ahmednagar district for a period of 2001 to 2016. Water surplus and the deficit were estimated by weekly rainfall and reference crop evapotranspiration. Results of the study revealed that weekly water availability   was very meagre during the rainy season in the Panrner nd Kopargaon tehsil. A number of   surplus weeks in this two tehsil were only four weeks which is less than 20 per cent weeks. It was observed that in the Akole tehsil highest 12 (50%) weeks were surplus followed by 9 weeks in Jamkhed tehsil. Remaining tehsils had existed water surplus only during 6 to 8 number of weeks in the district. In the Ahmednagar district rainfall is not sufficient to fulfil crop water requirement and needs supplemental irrigation facility to get maximum returns. Some of the weeks are showing water surplus in the many tehsils of the district, but its probability is less than 50 percent which is not assured.

Remote sensing and geographic information system (GIS) are two of the most important tools used to evaluate the morphometric characteristics of watersheds, as morphometric analysis of river basins using conventional methods, is very time to consume, laborious and cumbersome. In this study, the morphometric characteristics of the Adula watershed were calculated using ESRI- ArcGIS. The areal extent of the Adula watershed varies between 19°32’40” N to 19°43’2” N latitude and 74°10’15” E to 74°48’18” E longitude. The topographic sheets obtained from the survey of India on a scale of 1:50000 and the SRTM (Spectral Radar Topographic Mission) Digital Elevation Model of 30 m resolution, were used for watershed delineation and deriving the linear (stream order, stream number, bifurcation ratio), aerial (basin area, basin perimeter, drainage density, form factor, stream frequency, and circulatory ratio), relief (height of  outlet of watershed, basin relief, maximum height of watershed, total basin relief, absolute relief, relief ratio, ruggedness number) aspects. bifurcation ratio for varies from 3.0 to 8.33, indicating the elongated shape of the watershed. Drainage density factor values were 4.43 km/km2 indicating high drainage densities and 0.132 indicating an elongated basin with lower peaks respectively. Ruggedness number was 3.78 showing a dendritic and radial pattern with drainage texture. Therefore this morphometric analysis using geo-processing techniques employed in this study will assist in planning and decision making in the watershed development and management.

Background: Migraine is one of the most common types of headache; it is a chronic neurological disease that affects 15% of the population, however, information about its prevalence in Sudan is scarce.

Aim: The aim of this study was to study prevalence of migraine and trigger factors among adult rural Sudanese population in 2018.

Setting and Design: This is a cross sectional two-stage door-to-door community-based study conducted in 16 administrative areas in rural Sudan.

Materials and Methods: A sample of 8610 adult Sudanese individuals, 18 years and above was selected. A structured pretested questionnaire was used included questions about two or more headaches in the last three months for screening. Participants with at least one positive response were asked to perform the 3-item validated Identification of Migraine (ID Migraine) test. Data was analyzed by SPSS version 20 for descriptive statistics and one way chi square test was used for testing the association of triggering factors with migraine at 95% confidence level of significant.

Results:  Four hundred and sixty eight had migraine with a prevalence rate of 5.4% among 8610 study population. The prevalence of migraine was 40% among those having at least two episodes of headache. Females were significantly affected by migraine more than males, P- value 0.044. Migraine significantly decreases with increase in age showed the highest frequency among the age group 18-29 years (38.0%). Family history of migraine accounted to 83.4% of population with migraine. Population with migraine who experienced aura was 64.5%. Already diagnosed population with migraine was 38.9%.The most important triggering factors among population with migraine were irregular/lack of sleep followed by stress/anxiety, noise and fatigue/physical activity, 91.0%, 88.0%, 85.7% and 84.6% respectively. The females experienced migraine with menstruation accounted to 46.7%. Perceived migraine effect was moderate to severe on work/ daily activities/ leisure of 78.2% of population with migraine.

Conclusion: Migraine prevalence was alarming in this study. A gap exists in the diagnosis of migraine that needs efforts to reduce the sufferings of affected population.

The extraction of cellulose nanocrystals (NCC) from cotton textile waste, constituted by 70% long fibers and 30% cotton linter, was performed through the action of sulfuric acid followed by solution neutralization with two different alkalis, namely ammonia and sodium bicarbonate, which yielded microcellulose (MCC), then centrifuged to NCC. The action of the two alkalis was compared as for fiber repeatability and morphology, and the results obtained using ammonia were considered more suitable for possible introduction of NCC for the repair of historical paper artifacts. This evidence was obtained by applying optical/polarized light microscopy observation and dynamic light scattering (DLS) results.

Aims: Phosphorus and phosphate are broadly used in many areas ranging from advance researches to manufacturing companies for regular use purposes. In Togo, the raw phosphate is exploited and exported to serve as an ingredient in chemical fertilizers, detergents, phosphoric acid synthesis, etc. The aim of the present work is an investigation of alternative valuation of the raw phosphate of Hahotoé-Kpogamé in Togo.

Methodology: The study consists of the transformation of the raw phosphate into hydroxyapatite by dissolution followed by a precipitation. The hydroxyapatite thus obtained can be used, for example as a conditioning matrix of industrial waste, as a catalyst support, or for the depollution of water etc. The characterization was carried out by Fourier Transform Infrared Spectroscopy, X-Ray Diffraction, Thermogravimetric Analysis coupled to Thermal Differential Analysis and Inductively Coupled Plasma Atomic Emission Spectroscopy.

Results: These analyses revealed that the materials are predominantly of non-stoichiometric hydroxyapatite and minority of phosphate tricalcium and impurities. The synthesized materials (calcined and uncalcined) were applied as adsorbent and as coadsorbent of a photocatalyst (TiO2) for methylene blue removal. The study of the adsorption of the methylene blue was carried out in a batch mode. The adsorption of methylene blue on the synthesized materials gave a low yield (15 to 20%). However, used as in the mixture with titanium dioxide, the adsorption rate of methylen blue was increased significantly (57% of removal rate with 0.5 g synthesized materials + 2 g of TiO2 P25).

Conclusion:  uncalcined hydroxyapatite obtained from raw phosphate can be used as an efficient co-adsorbent of titanium dioxide leading to an alternative valorization of this natural phosphate.
