A protein of unusual characteristics has been identified in normal rat sera by electrophoretic separation at pH 8.6, followed by precipitation of each fraction with a cationic detergent. This protein, which is closely identified with albumin after electrophoresis at pH 8.6, precipitates with cationic detergent at a low pH in contrast to albumin which precipitates with detergent only at a high p...

This study describes the characteristics of the cross-equatorial northerly surge (CENS), a northerly flow that appears intermittently over the equatorial region between October and April, and its relationship to the precipitation patterns over the Maritime Continent. The CENS in this study was defined as the area-averaged northerly wind exceeding 5 m s 1 over 105 E–115 E, 5 S–EQ based on the Qu...

1. INTRODUCTION Across much of the United States, and in many parts of the world, winter precipitation can come in many forms. It can range from all-liquid rain, to partially frozen particles, and completely frozen particles such as ice pellets or snow. The results of winter precipitation, then, are highly dependent on what type of precipitation falls. If rain falls into subfreezing environment...

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...

introduction atmospheric circulation patterns leads to different weather conditions and rainfall regime change is controlled by seasonal and irregular variations of atmospheric circulation pattern. variety and climate change, such as drought and flood result in changes in the spatio-temporal of precipitation, one of the important parameters conditions mentioned, heterogeneity in moisture transm...
