damask rose (rosa damascena mill.) has high economic importance and commercial value. the plant essential oil is used for perfumery, food and medicinal industries. it is necessary to know much about seed germination for study of genetic variation and breeding improved varieties of r. damascena. in this study seed germination of r. damascena were evaluated, using thermal period treatments. the d...
Time-dependent insolation in a planetary atmosphere induces a mass quadrupole upon which the stellar tidal acceleration can exert a force. This “thermal tide” force can give rise to secular torques on the planet and orbit as well as radial forces causing eccentricity evolution. We apply this idea to the close-in gas giant exoplanets (“hot Jupiters”). The response of radiative atmospheres is com...
Perioperative hypothermia is a common and serious complication of anesthesia and surgery. Core body temperature, which is normally regulated to within a few tenths of a degree centigrade, can fall by as much as 6 degrees C during anesthesia. The combination of anesthetic-induced impairment of thermoregulatory control and exposure to a cool operating room environment causes most surgical patient...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
We prove weighted Littlewood-Paley inequalities for linear sums of functions satisfying mild decay, smoothness, and cancelation conditions. We prove these for general “regular” measure spaces, in which the underlying measure is not assumed to satisfy any doubling condition. Our result generalizes an earlier result of the author, proved on R with Lebesgue measure. Our proof makes essential use o...
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
In recent years with the development of cities coatings of the Earth's has changed surface. These changes have caused some urban areas to have a few degrees higher than the surrounding temperature. This phenomenon is known as thermal islands. Mashhad is one of the major metropolises in Iran with the problem of thermal islands. Various parameters affect the formation of thermal islands in this ...
Much research has suggested that facial identification has some characteristics of automaticity, in that it is rapid, nonconscious, and mandatory. However, little research has tested whether it can occur even if attention is already devoted to the demanding central processes of another task. In the present study, we addressed this type of automaticity using the psychological refractory period p...
For d ≥ 2, we construct a doubling measure ν on Rd and a rectifiable curve Γ such that ν(Γ) > 0.
