in this study we report the rock magnetic properties of surface soil samples and their spatialvariability from the northernmost district of kerala to understand pedogenic processes and soil erosion. themagnetic signal is mainly from fine grained pedogenic magnetite as other sources like anthropogenic andlithogenic magnetite, bacterial magnetite and greigite are absent. the surface soil samples ...

conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. in the recovery system, super-critical an co2 is employed as the working fluid operating in a brayton cycle. low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes the hot gases lea...

anxiety disorders are a group of psychiatric disorders which can have negative effects on the human life. children and adults can have anxiety disorders and these disorders can lead to secondary problems such as cognitive, perceptual, emotional and behavioral problems. for treatment of anxiety, the practitioners and psychologists can apply psychotherapy approaches such as: cognitive therapy, ge...

the term “system” is defined as «elements standing interaction». this implies that a change in any given element should bring about changes in other elements of the system and thus may be used to identify the boundaries of a system. a system can be a machine, a man, or a community. each of these may be part of a greater system (super system) or include several smaller systems (subsystems). syst...

the purpose of this study is comparison of manganese absorption capacity by natural and modified zeolite. for this purpose used by from semnan mines zeolite with mean particle diameter of 360 micrometer. for modified zeolite, 5 g amount of natural zeolite with 100 ml of 1 m sodium chloride solution mixed and maintained at 24 hours in room temperature. for measure specific surface of absorbents,...

increasing the concentration of ammonia in water can cause fish death. this study was conducted to compare the performance of conditioned activated carbon and zeolite in ammonia (tan = total ammonia nitrogen) removal in a simulated transport of rainbow trout fry in 40-liter plastic bags. hence, responses of zeolite and conditioned activated carbon in ammonia (tan) removal at different concentra...
