survey on the rule of the due & hindering relying on the sheikh ansaris ideas

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

Influence of sialic acid on the surface hydrophobicity of membranes

5-HIAA in the caudate nucleus (Alzheimer, 3.2 f 1.7; control, 5.2k2.3; P< 0.01), HVA in the caudate nucleus (Alzheimer, 13.5k5.0; control, 24.6k7.3; P<O.OI) and HVA in putamen (Alzheimer, 2.3 k0.9; control, 4.7k2.6; P<0.002). The highest CSF concentration of HVA is in the lateral ventricles, which are adjacent to the dopamine-rich caudate nucleus. Therefore, it seems likely that the CSF deficit...

Dynamic molecular recognition on the surface of vesicle membranes.

The ability of a vesicle-bound receptor to associate with a water-soluble ligand increases with membrane loading level and the presence of membrane additives with cationic N-CH3 groups.

Water relations of the pine exine.

BACKGROUND AND AIMS Water adhesion forces, water absorption capacity and permeability of the pine exine were investigated to consider a possible function of sporopollenin coatings in the control of water transport. METHODS The experiments were carried out with sporopollenin capsules obtained from pine pollen consisting of an empty central capsule and two sacci. Changes in the concentration of...
