GIS-Hydrogeochemical Model of the Yaoundé Fractured Rock Aquifer, Cameroon: Aquifer Setting, Seasonal Variations in Groundwater-Rock Interaction and Water Quality  [PDF]
Richard Ayuk II Akoachere, Omabgemi Omoloju Yaya, Sonia Ebot Egbe, Thomson Areakpoh Eyong, Bihmimihney Nelly Nji, Diana Besem Tambe
Journal of Geoscience and Environment Protection (GEP) , 2019, DOI: 10.4236/gep.2019.75018
Abstract:
This study of the gneiss-fractured-rock aquifer in Yaoundé capital of Cameroon determines: the aquifer setting-flow systems, the aquifer type, seasonal variations in rock-water interactions, evolution of the hydrogeochemical processes, physicochemical parameters and the suitability for domestic-agro-industrial use of the groundwater. Physicochemical field tests were carried out on 445 wells during four seasons for EC, pH, TDS, Temperature and static water level from July 2016 to May 2017. 90 well samples were analyzed 45 samples per season: wet/dry. 38 borewell logs were used together with structural data to determine the aquifer setting. The field physico-chemical and laboratory analysis data of well samples were mounted unto various GIS software platforms: Global mapper, AqQa, Aquachem, Rockworks, Logplot7, Surfer and ArcGIS, to get indices/parameters/figures, by use of Durov’s, Piper’s and Gibbs diagrams, Water quality index WQI, USSL ratio, Sodium Absorption ratio SAR, Percent sodium %Na, Kelly Ratio KR, Magnesium Absorption Ratio MAR, Total Hardness TH, Residual Sodium Carbonate RSC and Permeability Index PI that were determined. The process of groundwater ions acquisition is three-fold: by recharge through atmospheric precipitation, by ion exchange/simple dissolution between the rock-groundwater and by groundwater mixing in its flow path. Water types are Ca-HCO3, Mg-HCO3 and Mg-Cl while hydrogeochemical facies are Ca-Mg-HCO3 and Ca-Mg-Cl-SO4. Most water samples are
Seasonal Variations in Groundwater of the Phreatic Aquiferous Formations in Douala City-Cameroon: Hydrogeochemistry and Water Quality  [PDF]
Richard Ayuk Akoachere, Sonia Ebot Egbe, Thomson Areapkoh Eyong, Sophie Ngomune Edimo, Simon Ngomba Longonje, Diana Besem Tambe, Nji Bihmimihney Nelly
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105328
Abstract:
This study was to determine the seasonal variations of groundwater, the influence of the rock formations on the groundwater solute chemistry and groundwater domestic-agro-industrial quality using hydrogeochemical tools and physicochemical parameters; Ionic ratios, Gibbs diagrams, Piper diagrams, Durov diagrams and water quality indices. From physicochemical parameters; in the rainy season, pH ranged from, 4.6-7.1; EC, 0.023-1.63 mS/cm; Temperature, 26.3-290C andTDS, 0.015-1.09 mg/L and in the dry season pH ranged from 5-7.2; EC, 0.01-1.61 mS/cm; Temperature, 24.4-29.50C andTDS, 0.01-1.08 mg/L. Forty groundwater samples; 20 per season, wet and dry were analysed. Themajor ions fell below WHO acceptable limits for both seasons. The sequences of abundance of major ions were, Ca2 >K >Mg2 >NH4 >Na , HCO3->Cl->SO42->NO3->HPO42- in wet season and Ca2 >Mg2 >K >Na >NH4 , HCO3->Cl->SO42->HPO42->NO3- in dry season. Ion-exchange, simple dissolution and uncommon dissolution processes determined groundwater character. Groundwater ionic content was as a result of ion exchange from rock-weathering. Water types are; MgCl and MgHCO3 in both seasons. Hydrogeochemical facies are; Ca-Mg-Cl-SO4, characteristic of groundwater some distance along its flow path and Ca-Mg-HCO3, characteristic of freshly recharged groundwater from precipitation. The groundwater indices of; Sodium Percent (% Na), Residual Sodium Carbonate (RSC) , Kelley’s ratio (KR), Sodium Adsorption Ratio (SAR), Electrical Conductivity (EC), Total Dissolved Solid (TDS), USSL? and Wilcox index were determined, evaluated and found to be suitable for agro-industrial uses in all seasons. Permeability Index (PI) , Water quality index (WQI) and Magnesium Adsorption Ratio (MAR) were not suitable in some areas and in some seasons.

The dialogue between religion and science: truths, ideas and beliefs
?uro ?u?nji
Singidunum Journal of Applied Sciences , 2012,
Abstract: Science and religion are two distinct but not two hostile paths: two ever valuable efforts of human spirit! Science and religion would have less intellectual disputes and social conflicts if only both of them would explicate their principles, and then in even dialogue, espy and evaluate possibilities and frontiers of their principles and sorts of enabled questions and answers. Religion might be interesting for science as it opens new and unknown fields of human experience. Frontiers of science and religion are historically changeable, which does not mean that they can escape. Religion is not a sort of less developed science, but an independent way of thinking, beliefs and actions, offering to believer a solution of some problems otherwise unsolvable, even by assistance of science and its methods.
Social Production of Space: “Lived Space” of Informal Livelihood Operators; the Case of Dares Salaam City Tanzania  [PDF]
Nelly John Babere
Current Urban Studies (CUS) , 2015, DOI: 10.4236/cus.2015.34024
Abstract: This paper critically examines the social production of space for informal livelihood activities. While many progressive scholars have embraced the idea of eviction and harassment of the informal livelihood operators, what these scholars have often left unexplored is how informal operators contribute to the social production of space in urban areas. The first half of this paper focuses on the idea of Lefebvre’s conceptualisation of social production of space and the linkage with the informal livelihood activities. The second section focuses specifically on how social production of space is manifested in the operation of the informal livelihood operators. I argue that informal mode of production of space should be considered to inform how spaces for such activities are produced.

Las organizaciones empresariales venezolanas bajo el gobierno de Hugo Chávez (1999-2007): ?De la sociedad civil nacional a la internacional?
Arenas,Nelly;
Cuadernos del Cendes , 2009,
Abstract: this paper examines the new relationships established by the venezuelan state with old and new business associations. it analyzes the period beginning with hugo chávez election to the presidency in 1999 and ending with the re-election in 2007. venezuela has witnessed a process of displacement of the old business associations by new ones born under the umbrella of the chavist project, giving rise to a sort of state corporativism. as a result, the venezuelan state has lacked the domestic checks and balances needed for decision-making in economic matters, with this role being played by the association grouping the large international oil consortia. the balances concerning hydrocarbon thus come from a civil society that is not national, but international

Los pliegues de lo local en el mapa de lo global: reticencia y resistencia
Richard,Nelly;
Signo y Pensamiento , 2006,
Abstract: the article describes the new forms for resistance in the economic and semiotic grids of the capitalist continuum. empire, with its globalized signs of cross-border nature, has replaced the old symbols of deeply rooted traditions and belonging. it is a 'trans-semiotic' grid of connectivity and 'non-differentiation', marked by the perpetual movement of meanings and the speed of exchanges. as a proposal, it moves forward in the concept of 'hybridity', through the problem of 'cultural tradition', which ends up bringing about ruptures between what is global and what is local through the transfer of meanings from one chain to another. in spite of those who insist that 'local' is not out of the global order, the "no place" opposes "all places" of the empire. this figure represents the liberating conditions of crowds, which is "to be against in all places", a characteristic that is not local -as a place- but of production of locality, that is, non belonging and permanent 'de-inscription'.
