the research was conducted in order to determine the bending stress, young’s modulus, shearing stress, and shearing energy of safflower stalk as a function of moisture content and stalk region. the bending forces were measured at different moisture contents and the bending stress and the young’s modulus were calculated from these data. for measuring the shear forces, the stalk specimens were se...

Isotherm curves are useful for the designing of dryer as well as controling of the seed moisture content during storage and drying process. To study the curves, this research was performed on the basis of two factorial experiments including three factors: (1) hybrid at two levels (Three Way Cross 647 and Single Cross 704) (2) temperature at 6 levels (from 5 to 55°C) and (3) Relative Humidity (R...

soil compaction and moisture content are two of the factors that greatly influence variations in crop yield. capacitance-based sensor is a sensitive device for estimating soil water content. in this method of soil moisture content measurement, soil acts as the dielectric of the capacitor. throughout this research work, a capacitance-based moisture sensor that can measure the soil moisture conte...

Introduction: Biofiltration of volatile organic compounds is a biological method in which air containing contaminant is passed through a packed bed and the pollutant is transferred from gas phase to biofilm where it is degraded by microorganisms. Degrading microbial activity is strongly influenced by moisture content of bed so that it is considered as the most important factor for controlling o...

The use of sunscreens should also be recommended in order to work against all kind of ultarviolet (UV)-induced skin damage such as photoallergies, skin wrinkles, sunburn or even skin cancer. Sunscreens contain chemical filters (organic absorb regularly UVB radiation) and physical filters (e.g., TiO2 and ZnO). The second group has been said to reflect and scatter UVB and UVA radiation. TiO2 is ...

knowledge of the aerodynamic properties of agricultural materials is needed in equip-ment design for operations such as pneumatic conveying in loading/unloading operations of corn silage into/from silos. while considerable information is available on seed grains, little is known about the aerodynamic behavior of corn (zea mays l.) silage. in this re-search, the weighed mean terminal velocity of...

one of the most important theoretical concepts in international relations is the concept of ‘state’, in relation to which all of the theories and discourses reflect their viewpoints. however, sometimes there are said to be falls in state-nations. islamic-jurisprudential discourse and critical western discourse, admitting the role of state as a key element in international relations and respecti...

this study was conducted to investigate the effect of soil moisture content in primary tillage and travel speed during disking operation on the performance of an offset disk harrow in a silty clay loam soil. at first, the effect of three soil moisture content ranges of (12-14), (14-16) and (16-18) percent (dry basis) on soil clod size (left from moldboard plowing) was investigated. then, the pe...
