a pure silicate host namely sr2mgsi2o7 as a support for a long-lasting afterglow when dopped with rare-earth elements was sought after. to this end the process of obtaining firing temperatures of the above mentioned phase in normal condition was carried out using suggested wet and dry methods. the degree of purity obtained in these preparatory methods as well as the different firing temperature...

This research is a study on the relationship of irrigation water treatments and soil moisture distribution uniformity (DU). Soil moisture distribution was based on long-term data sets that were collected during wet and dry soil conditions (from permanent wilting point to field capacity) using a novel electromagnetic sensor-based platform moving inside subsurface horizontal access-tubes. The irr...

This study investigated experimentally and theoretically, how condensate and initial formation of a thin frost layer on the surface of the evaporator affects the evaporator performance of room air-conditioners compared to dry coil conditions. The theoretically obtained results were validated with the measured values in both wet and initial frost formation conditions and a good correlation was f...

statement of the problem: fissure sealant therapy is among the most effective methods of preventing dental caries. however, it is lengthy and isolation of the teeth is difficult in this procedure especially in young children. using new hydrophilic fissure sealant may reduce such problems. purpose: this study aimed to evaluate the clinical success of a hydrophilic fissure sealant on the lower pe...

results the results showed that the average hr at resting, sitting (32℃ ± 0.1℃), and light workload (30℃ ± 0.1℃) were 78.52 ± 12.10, 69.74 ± 11.98, and 110.78 ± 17.91 beat/min, respectively. the average of ear canal temperature was estimated at 36.70℃ ± 0.36℃ for sitting workload and at 36.71℃ ± 0.27℃ light workload. conclusions the findings of this study illustrated that the average hr and the...

Introduction: Tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .This paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  Materials and Methods: Sixty re...

In xeric environments, water-use efficiency (WUE) is likely to be a target of natural selection. Higher WUE is expected to confer a fitness advantage in drought conditions, but this prediction has rarely been tested. To examine the relationships between WUE and fitness, two common garden experiments were conducted. Inbred lines of Impatiens capensis derived from wet and relatively dry sites wer...
