1846 Countries in Sub-Saharan Africa won fewer concessions on their exports in the Uruguay Round than did other developing countries, but they still emerged facing fewer or lower restrictions than others. They should be more active in the next Round, focusing negotiations not on trade preferences but on bound most-favored-nation tariff reductions. Summary findings Openness and liberal trade pol...

Cesium manganese chloride (CsMnCl3) nanocrystals (NCs) have recently been recognized as potential lead-free perovskite candidates for red emission. To ascertain how the luminescence properties depend on NC structures formed under different synthesis conditions, we synthesized CsMnCl3 NCs in two polymorphic structures, namely, cubic (c-CsMnCl3) and rhombohedral (r-CsMnCl3), by tuning reaction te...

In the past 5 years, we have witnessed an increased interest in developing secondary aluminum–sulfur (Al–S) batteries. One of main obstacles to further advance this technology is large overpotentials observed during recharge battery, which a extent are related insulating nature discharge product, namely Al2S3. The present work aims elucidate mechanisms responsible for ionic and electronic trans...

Abstract Earthquake leads to a disaster by creating massive damage on the surface of earth. A framed structure reduces impact an earthquake. In these types structures, shear wall plays vital role resisting horizontal effectively. The is flexural members that effectively resist displacement providing adequate stiffness structure. this work, behavior considering location in different under seismi...
