Modern Islamic economics often centers on utility-value concepts derived from Western economic thought. There is a pressing need for Islamic economics to redefine core economic theories, particularly the utility theory of value, through a holistic and deductive approach. This paper explores the concept of Homo Islamicus as an alternative to Homo Economicus, emphasizing its potential to incorporate cognitive processes and ethical considerations into economic behavior. By focusing on cognitive development and ethical values, the Homo Islamicus model proposes a comprehensive framework for economic actions, challenging traditional one-sided economic approaches. The study critically analyzes the transformation required in economic theories to support this model and its implications for the future of Islamic economics.
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 en 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 subórdenes 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, 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.
The objective of this study was to develop polymeric microspheres utilizing sulfasalazine and dexamethasone with okra gum and hydroxypropyl methylcellulose (HPMC). Recent advancements in microsphere technology, including patents on nanocapsule formulations, informed the selection of drug and polymer combinations. The microspheres were formulated using a solvent extraction technique, and their efficacy was assessed through various analytical methods. Fourier-transform infrared spectroscopy (FTIR) revealed no significant interactions between the drugs and polymers, while differential scanning calorimetry (DSC) confirmed molecular dispersion within the microspheres. Dissolution studies demonstrated an extended drug release up to 8 hours when utilizing the combined polymers compared to their individual use. The findings suggest that the concentrations of Okra gum and HPMC significantly impact the recovery, entrapment efficiency, hydration, and drug loading of the microspheres. The study concludes with the successful preparation of Okra gum/HPMC microspheres, emphasizing their potential in sustained drug delivery systems.
