the concepts of similarity and dissimilarity have been the interest of many researchers. basically, in the studies the similarity between two objects or phenomena, has been discussed. in this thesis, we consider the case when the resemblance or similarity among three objects or phenomena of a set, 3-similarity in our terminology, is desired. later we will extend our definitions and propos...
in this study, a landrace melon zarde jalali as the scion and commercial varieties of cucurbita rootstocks cv., shintozwa and ferro-rz was used as the rootstock. grafted plants upon commercial varieties of cucurbita with own-rooted and ungrafted at three irrigation levels of 60, 80 and 100% (respectively 4984.32, 6124.82 and 7239.41 m3ha-1) based on total available water depletion with drip irr...
Nowadays, many vegetables are grown inside greenhouses in which environment is controlled and nutrition can be supplied through water supply using electrical pump, namely fertigation. Dosage of nutrition in water for many vegetable plants are also known so that by controlling water supply all the needs for the plants to grow are available. Furthermore, water supply can be controlled using elect...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
despite the different criticisms on contrastive analysis it has been proved that the results of it(when processed) can be useful in a tefl environment, specially at the level of phonology.this study is an attempt to compare and contrast the sound systems of kurdish and english for pedagogical aims.the consonants,vowels,stress and intonation of the two languages are described by the same model...
Crassulacean acid metabolism (CAM) is an important elaboration of photosynthetic carbon fixation that allows chloroplast-containing cells to fix CO2 initially at night using phosphoenolpyruvate carboxylase (PEPC) in the cytosol. This leads to the formation of C4 organic acids (usually malate), which are stored in the vacuole. Subsequent daytime decarboxylation of these organic acids behind clos...
Backgrund: Saffron petals contain flavonoid compounds, glycosides, and anthocyanins. Considering the trend of increasing the use of medicinal plants in modern medicine in order to treat some diseases, the upcoming experiment was designed to investigate the effectiveness of the hydroalcoholic extract of saffron petals and alkaline water in comparison with the commercial drug metformin on the blo...
Micropropagated plants are usually cultured in in vitro environments, with a high relative humidity and low light intensity, taking nutrients and energy from the culture medium. During acclimatization, physiological and structural changes allow micropropagated plants to adapt to the new environmental conditions, mainly to low relative humidity and high light intensity. As a result, plants becom...

Frost is the coating or deposit of ice that may form in cold conditions, usually overnight. If the temperature drops far enough for the plant cells to freeze, non hardy plants will die. Therefore, a research was laid out to study the influence of an anti-frost solution on growth, flowers quality and biochemical parameters of ornamental plants. The anti-frost solution was applied as foliar spray...
