Digestive enzymatic activity and nutritional responses of Autographa gamma (L.) (Lepidoptera: Noctuidae), an important insect pest of sugar beet, on nine sugar beet cultivars (Peritra, Karolina, Paolita, Lenzier, Tiller, Ardabili, Persia, Rozier, and Dorothea) were studied. The highest proteolytic activity of fourth and fifth instar of A. gamma was in larvae fed on cultivar Persia. The highest ...

One way to probe earthquake nucleation processes and the relation between stress buildup and seismicity is to analyze the sensitivity of seismicity to stress perturbations. Here, we report evidence for seasonal strain and stress (~2–4 kPa) variations in the Nepal Himalaya, induced by water storage variations which correlate with seasonal variations of seismicity. The seismicity rate is twice as...

The Iranian plateau is an ideal area for investigating the relationship be? tween ecological and sociological factors because of its stark aridity, on the one hand, and its historical role as a meeting place of ethnic and cultural movements on the other. The part of the plateau which forms the southeast corner of Persia is particularly interesting from this point of view. Over an area of some 2...

studying the history of science in ancient civilizations can help to shed light on the mysteries of the history of science as well as the contribution of nations to the growth of science in the world throughout the history. among various branches of science, medicine is of particular importance and owing to the crucial role of physicians in this discipline; the present study has taken the role ...

In most cases of reservoir-induced seismicity, seismicity follows the impoundment, large lake-level changes, or filling at a later time above the highest water level achieved until then. We classify this as initial seismicity. This ‘‘initial seismicity’’ is ascribable to the coupled poroelastic response of the reservoir to initial filling or water level changes. It is characterized by an increa...

Existing loading protocols for quasi-static cyclic testing of structures are based on recordings from regions of high seismicity. For regions of low to moderate seismicity they overestimate imposed cumulative damage demands. Since structural capacities are a function of demand, existing loading protocols applied to specimens that are representative of structures in low to moderate seismicity re...
