The supply of safe drinking water to rural communities has always been challenging, unlike in most large cities where government authorities have constructed central systems. In many areas, primary sources such as surface and groundwater are at risk contamination with rapid agricultural industrial growth climate change-related issues. Rainwater harvesting is an ancient practice for communities,...

In the present paper, electrical energy harvesting from random vibrations of an Euler-Bernoulli nano-beam with two piezoelectric layers is investigated. The beam is composed of an aluminum layer together with two piezoelectric ceramic layers (PZT 5A) serving as energy harvesting sensors. In the proposed method, the equations governing the bimorph nano-beam will be analytically derived using cla...

Six Iranian accessions of Cucumis melo, including Inodorus, Cantalupensis, and Dudaim groups, were planted and then harvested at two harvesting stages including 21 and 28 days after anthesis for Dudaim group and 28 and 38 days after anthesis for Inodorus and Cantalupensis groups. At the time of harvest, we measured some quality parameters and appearance indices of fruits, such as the number of ...

Seed dormancy controls the start of a plant's life cycle by preventing germination of a viable seed in an unfavorable season. Freshly harvested seeds usually show a high level of dormancy, which is gradually released during dry storage (after-ripening). Abscisic acid (ABA) has been identified as an essential factor for the induction of dormancy, whereas gibberellins (GAs) are required for germi...

In this paper, the different variables that characterize the soybean crop in Argentina are analyzed. The main objective is to obtain information that will be useful for the analysis of the environmental consequences of the progress of this crop in the country. This has been made by a descriptive statistical analysis and a factor analysis was used to identify factors which characterize the soybe...
