kermanshah province is the main producer of various chickpea cultivars in iran. in this study a laboratory peg-tooth thresher was employed for chickpea threshing. the effect of cylinder speed (9, 12, 15 m/s), concave clearance (12, 14, 16 mm), feed rate (80, 160, 240 kg/h) and material moisture content (5, 10, 15% w.b.) was studied on percentage of grain damage, threshing efficiency and percent...

Almond is one of the most important nut crops in Iran. Due to the suitable climatic conditions, Iran is one of the most important growing centers for wild and domesticated species of almond in world. Native genotypes typically are early flowering, due to late spring frost, often; they have been damaged. So frost damage to the flowers and early developing fruits is one of the most limiting facto...

Since muscles support almost all the activity of our bodies, the relationship between aging and muscle capability is important. Dr. Edgar Arriaga from the Department of Chemistry studies the effect of age on muscle damage for different muscle types and cell regions. As part of the summer statistical collaboration program, I was on a team that collaborated with them to analyze data from a recent...

The electrostatic discharge (ESD) effect in GMR heads in the deshunting process is studied in order to prevent the damage in this process. The simulation and experiment results are investigated and compared. It is found from these results that sequences of deshunting process, currently operating, can cause the damage of GMR heads due to the ESD effect, based on the charged device model, CDM. Th...

One of the difficulties of the vibration-based damage identification methods is the nonuniqueness of the results of damage identification. The different damage locations and severity may cause the identical response signal, which is even more severe for detection of the multiple damage. This paper proposes a new strategy for damage detection to avoid this nonuniqueness. This strategy firstly de...

BACKGROUND The effect of herbivory on plant fitness varies widely. Understanding the causes of this variation is of considerable interest because of its implications for plant population dynamics and trait evolution. We experimentally defoliated the annual herb Arabidopsis thaliana in a natural population in Sweden to test the hypotheses that (a) plant fitness decreases with increasing damage, ...
