iran is a country in the middle part of the alp-himalayan orogeny system that have huge earthquakes. the risk of the earthquakes is the cause of the researches about the precursors. because earthquakes occur suddenly, often with devastating consequences, earthquake prediction is a matter of great interest among the public and emergency service officials. a few observations suggest that some ear...

this study was conducted to determine the nutritional value of seaweed gracilariopsis persica and to evaluate its utilization in layer nutrition. metabolizable energy and chemical composition of seaweed were measured. 100 hy-line w-36 hens were allocated to five dietary groups with five treatment group (experimental diets containing zero, five, 10, 15 and 20 percent seaweed) and it lasted for 1...

introduction rhodium metal is known for its stability in corrosive environments, physical beauty, and its unique properties. rhodium is now widely used for alloying platinum in thermocouples, crucibles, evaporating dishes, weighing boats windings for high-temperature furnaces. it has been applied as a coating material because of the hardness and luster of its surface. rhodium is present at abou...

this study was conducted to determine water stress tolerance of two iranian dudaim melons (kerman & birjand) and one iranian muskmelon (samsoury). throughout the experiment, three different levels of irrigation with three irrigation starting points (-50, -65 and -75 cb of matric potential) were employed. results indicated that water stress significantly affected yield, firmness, fruit sugars as...

background and purpose     methods:     results     conclusion:

seed rot caused by pythium ultimum is an important disease of safflower in iran and other countries. therefore, finding the genetic sources of resistance and releasing of resistant cultivar is considered as important objective by safflower breeders. this disease will spread when air humidity and the moisture in the soil are sufficiently prepared and this situation occurs exactly in the time of ...

five levels of salicylic acid (sa), (0, 2, 4, 6 & 8 mm) were sprayed on strawberry cv. comarosa fruit bearing plants in a hydroponic culture. growth, yield & fruit quality attributes were assessed. vegetative characteristics (crown number, root & shoot weight), reproductive traits (yield, fruit number as well as shape), fruit quality, macro elements (ca, mg, k & p), dry weight & ash were evalua...

this study was conducted to investigate the effects of using gracilariopsis persica in layer diet on performance, egg quality and lipids of blood serum of layer hens. one-hundred hy-line w-36 hens were allocated to five dietary treatments (experimental diets containing 0, 5, 10, 15 and 20 percent seaweed) and five replicates and four birds in each for 12 week period (23-34 week of age). the res...
