in mammals, the intrauterine condition has an important role in the development of fetal physiological systems in later life. suboptimal maternal environment can alter the regulatory pathways that determine the normal development of the fetus in utero, which in post-natal life may render the individual more susceptible to cardiovascular or metabolic adult-life diseases. changes in the intrauter...

there has been some decline in the land potential capacity in many developing countries, and depending on location,the multi objective management strategy of agroforestry can make effective use of natural resources to be feasible.environmental principles which are effective on agroforestry systems and their components, together with climaticfactors, are the important parameters which been evalu...

totoday’s market place is increasingly dynamic and volatile. in this area supply network issues recently have attracted a lot of attention from industrial practitioners and academics worldwide. chaos theory is the study of complex, nonlinear, dynamic systems. for chaotic systems, a tiny change in conditions may result in an enormous change in system output, whereas substantial changes in condit...
