There are utility-value oriented studies at the center of modern Islamic economics that belong to western economic thought. Islamic economics needs to include a holistic development that will redefine the basic concepts of economic theory, notably, utility theory of value. This process should be scrutinized by a deductive approach, not by going against the inductive approach and the analysis results. Islamic economists ought to become too specialized on a content that suggests new mentalities to available models rather than methodology discussions. From this point of view, the transformation in the concept of Homo Islamicus that is the alternative of Homo economicus approach needs to rise on economic foundations. The originality of Islamic economics can be provided by ensuring it to stay on holistic approaches deny one-sided approaches. In this regard, the concept of Homo Islamicus that has been put forward against the concept of Homo economicus should be discussed by a holistic attitude. A Homo Islamicus approach that makes a human into an inbeing that can actualize cognitive processes and intellectual analysis in the first place will be better. The concept of Homo Islamicus will be the core of the economic behaviors if we accept economics as a cognitive discipline. The human as the Homo Islamicus will be a human model that can complete his/her cognitive development and bring ethical values to the forefront. This research analyzed The concept of Homo Islamicus as an approach that will eliminate the concept of homo economicus by ethical criteria and cognitive development.
El uso de las tierras en función del desarrollo agropecuario, con su consecuente impacto en la economía nacional, es de gran importancia en Cuba, sobre todo en el actual contexto donde se pretende hacer producir a las tierras ociosas a partir del Decreto Ley 300. En la presente investigación, se estudia la distribución espacial de los principales suelos dedicados a la agricultura la provincia de Mayabeque. Con este fin se analiza la superficie que estos ocupan, sus principales factores limitantes y potencial productivo para los principales cultivos de interés económico en la región de estudio. Además, se propone un grupo de acciones encaminadas a lograr la explotación sostenible de este recurso sobre la base del equilibrio oferta - demanda ambiental. Como resultado de la investigación se evidenció que los suelos que predominan en la provincia de Mayabeque son los del Orden Oxisol, que representan el 33.90 del Total, seguido por los del Orden Inceptisol con el 20.40 %. Mientras que los suborden de suelo menos representativos son los Udox, los Ustalf y los Ustept, entre otros. Siendo sus principales factores limitantes agroproductivos la poca profundidad efectiva, el mal drenaje de los suelos y la erosión y la compactación, entre otros.
Very recently, the National Toxicology Program reported a correlation between exposure to whole body 900 MHz radiofrequency radiation and cancer in the brains and hearts of Sprague Dawley male rats. This paper proposes the following explanation for these results. The neurons around the rat’s brain and heart form closed electrical circuits and, following Faraday’s Law, 900 MHz radiofrequency radiation induces 900 MHz electrical currents in these neural circuits. In turn, these 900 MHz currents in the neural circuits generate sufficient localized heat in the neural cell axons to shift the equilibrium concentration of carcinogenic radicals to higher levels and thus, to higher incidences of cancer. This model is then applied to mice and humans.
Objective: To develop and to make effective polymeric microspheres of sulfasalazine and dexamethasone by using okra gum and hydroxypropyl methylcellulose (HPMC) was the objective of this study. The recent patents Microspheres comprising nanocapsules containing a lipophilic drug (US 20090011009 A1), Sustained release microspheres and preparation US (US6036976 A) helped in selecting the drug and polymers\nMethod: To formulate sulfasalazine and dexamethasone loaded okra gum/HPMC microspheres technique of solvent extraction was used. The effectiveness of Okra gum and HPMC in microspheres of sulfasalazine and dexamethasone in combination was studied. Pods of Hibiscus esculentus was used to extract okra gum. \nResults: No significant difference was observed between drug and polymers by FTIR spectra. Molecular dispersion of sulfasalazine and dexamethasone was observed by DSC studies. Dissolution studies were performed also to evaluate release kinetics of drug, which showed that drug release was retarded up to 8 hours by Okra gum and HPMC as compared to HPMC and okra gum when both were used alone.\nConclusion: Okra gum/HPMC microspheres of sulfasalazine and dexamethasone were prepared triumphantly by using the method of solvent evaporation. Recovery, entrapment effectiveness hydration and drug loading of microspheres may be influenced by the concentrations of Okra gum/HPMC.
