The primary objective of this research is to delineate potential groundwater recharge zones in the Kadaladi taluk of Ramanathapuram,Tamil Nadu,India,using a combination of remote sensing and Geographic Information Systems(GIS)with the Analytical Hierarchical Process(AHP).Various factors such as geology,geomorphology,soil,drainage,density,lineament density,slope,rainfall were analyzed at a specific *** layers were evaluated for quality and relevance using Saaty's scale,and then inte-grated using the weighted linear combination *** weights assigned to each layer and features were standardized using AHP and the Eigen vector technique,resulting in the final groundwater potential zone *** AHP method was used to normalize the scores following the assignment of weights to each criterion or factor based on Saaty's 9-point ***-wise matrix analysis was utilized to calculate the geometric mean and normalized weight for various *** groundwater recharge potential zone map was created by mathematically overlaying the normalized weighted *** layers indicating major elements influencing groundwater occurrence and recharge were derived from satellite images.2 Results indicate that approximately 21.8 km of the total area exhibits high potential for groundwater *** recharge is viable in areas with moderate slopes,particularly in the central and southeastern regions.

One of the key challenges in neuroscience is that the central nervous system(CNS;the brain and spinal cord), is largely unable to regene rate after injury. One factor contributing to this lack of repair is the accumulation of cellular and myelin debris at the site of injury. The debris is not efficiently phagocytosed and can persist for years after the initial injury, resulting in an inflammatory environment which inhibits axonal regrowth(Lutz and Barres, 2014).

The aim of this study was to develop a new approach for the preparation of environmentally friendly, high-value products from oily cold rolling mill(CRM) sludge. Utilizing oily CRM sludge as a source of iron, strontium hexaferrite(SrFe_(12)O_(19)) powders were prepared by multi-step processes involving acid leaching, chemical conversion treatment, and synthesis by a citrate precursor. The influences of citric acid dosage and the pH of the sol system on the formation, crystallite size, and magnetic properties of the obtained SrFe_(12)O_(19) powders were investigated. High saturation magnetization(74.8 mA·m^2·g^(–1)) and intrinsic coercivities(614.46 mT) were achieved for pH 7.0 of the sol system, for which the molar ratio of citric acid dosage to the total dosage of Fe^(3+) and Sr^(2+) was 1.5. This study presents a new approach to utilizing oily CRM sludge, and even refractory iron-containing solid waste.

OECs for spinal cord repair： Is repairing the iniured spinal cord by olfactory ensheathing cell （OEC） transplantation pos- sible？ A recent human trial in which a paralysed man regained some function after transplantation of partially purified OECs suggests that this therapy may be a successful approach （Ta- bakow et al., 2014）. In another human trial in which olfactory mucosa lamina propria was transplanted, patients recovered some motor and sensory function （Wang et al., 2015）. While these results show promise, it is clear that improvements are needed to provide patients with increased functional output. Strategies to improve the therapeutic use of OECs may include improving the purification of the OECs used for transplantation, using them in combination with growth factors to combat the inhibitory environment and improve anon growth, the use of nerve bridges, advanced physiotherapy and the use of exo- skeleton robotics to reinforce functional connections. Of all these approaches, it is probably is primarily addressed to ensure crucial that the purity of OECs consistency in outcomes.

The developing olfactory system - merging of the periph- eral and central nervous systems： The olfactory system is responsible for the sense of smell and is comprised of a complex topographic map that regenerates throughout life. In rodents each olfactory sensory neuron expresses one of N 1,300 odorant receptors with the neurons being distributed mosaically within the epithelium. The axons of the sensory neurons do not maintain near-neighbour relationships and instead project to disparate topographic targets in the olfac- tory bulb within the central nervous system. The develop- ment of the targets relies on the intermingling of the sensory axons with the interneurons, glia and second order neurons of the olfactory bulb. Thus the formation of the olfactory system involves the coordinated integration of the axons of the peripheral olfactory sensory neurons with the cells of the olfactory bulb.
