The control of plant transpiration by stomata under water stress and recovery conditions is of paramount importance for plant performance and survival. Although both chemical and hydraulic signals emitted within a plant are considered to play a major role in controlling stomatal dynamics, they have rarely been assessed together. The aims of this study were to evaluate (i) the dynamics of chemic...

Due to climate change, in the next 30-50 years, an increase precipitation during growing season is predicted Non-Chernozem zone of Russia. However, even now, traditional methods draining poorly permeable soils a number cases have proved be ineffective due insufficiency operational and capital measures accelerate removal surface water weak hydraulic connection between arable layer drains. The ex...

This paper presents the design of a highly efficient pneumatic motor system. The air engine is currently the most generally used device to convert potential energy of compressed air into mechanical energy. However, the efficiency of the air engines is too low to provide sufficient operating range for the vehicle. In this study, the energy contained in compressed air/pressurized hydraulic oil is...

This paper presents a method to predict and evaluate effects of hydraulic fracturing jobs by using reservoir and well flow numerical simulation. The concept of the method i5 that steam production rate at the operating well head pressure is predicted with different fracture conditions which would be attained by the hydraulic fracturing jobs. Then, the effects of the hydraulic fracturing is evalu...

Conscientious objection (CO) is the refusal to obey laws due to moral, religious or belief principles. The ideologies or religions underlying laws or constitutions have been seldom analyzed. Scientific Ethics finds that constitutions and laws have implicit or explicit ideological elements that are imposed on citizens, and denies or forbids others that lead citizens to CO. Ideological analysis i...
