Background and Objective: Anopheles maculipennis is one of the most important species of mosquito that can cause serious public health problems worldwide and applying insecticides and synthetic repellents are the current methods used for its control. The continuous application of these chemicals increases the probability of resistance, reduces insecticide efficiency and causes environmental pro...

Water infiltration into granular soils and the associated pore water pressure increase reduction in shear strength can trigger landslides, instability of vertical cuts failure retaining walls. Water-repellent reduce to maintain soil suction. Recent research has demonstrated creation synthetic water-repellent using chemical methods. This paper investigates a biological treatment for creating san...

to introduce ecologically safe acaricide, effects of essential oils derived from cuminum cyminum (cumin), syzygium aromaticum (clove), and mentha spicata (spearmint) were determined on tetranychus urticae at 25±1◦c, 65±5% rh and a photoperiod of 16:8 (l:d) hour. the essential oils extracted by hydro-distillation were characterized by means of gc and gc–ms. bioassays were performed by filter pap...
