We study the impact of heterogeneity of nodes in the zone conception of clustered Wireless Sensor Networks. Most of the classical heterogeneous clustering protocols consider the sensing field as a whole for cluster formation. Unlike the existing protocols, the proposed protocol creates rectangular fields called zones and the number of cluster heads elected depends on the zone size and the numbe...
در این تحقیق به منظور مطالعه زیست چینه نگاری و محیط رسوبی سازند آسماری یک رخنمون در برش خرامه (جنوب شرق شیراز) به ضخامت 160 متر به همراه 70 مقطع نازک مورد مطالعه و بررسی قرار گرفت. برش خرامه از نظر سنگ چینه شناسی شامل، آهک متوسط تا ضخیم لایه خاکستری کرم رنگ تا نخودی می باشد. بر اساس زیست چینه نگاری 18 جنس و 21 گونه از روزن داران بنتیک شناسایی گردید. در برش خرامه چهار بیوزن معرفی گردید. 1- numm...
This study aimed to determine the effect of hardness change according to penetration depth in the laser fusing zone and observed the correlation of the microstructure as an Nd:YAG laser was irradiated to Ni-Cr alloy for dental use by setting the spot diameter size to various conditions. In all groups, the hardness depth profiles in the laser fusing zone and heat-affected zone (HAZ) had larger v...
the dehno granite massive is located in the east dehno village and southern khomein city and within themetamorphic sanandaj–sirjan zone. the composition of these rocks include: granodiorite, quartzdiorite(tonalite), monzogranite and leucogranite. quartz, alkali feldspar, plagioclase, biotite, andalusite, hornblendemuscovite, tourmaline, zircon and apatite are examples of the existing major and ...
Background Cervical cancer is the fourth most common cancer among women worldwide. Organized cervical screening and vaccination against human papilloma virus (HPV) have been successful interventions for prevention of invasive cervical cancer (ICC). Because of cultural and religious considerations, ICC has low incidence in Iran and many other Muslim countries. There is no organized cervical scre...
In the setting of acute myocardial infarction, pharmacologic intervention resulting in afterload changes are common but the effect of these changes on regional left ventricular function, and specifically the functional border zone, has not been fully investigated. Accordingly, we studied the effects of afterload manipulation on circumferential flow-function relationships and the functional bord...
CONTEXT Dental caries, a ubiquitous multifactorial infectious disease, is primarily caused by microorganisms like Streptococcus mutans and Lactobacillus acidophilus. Use of antimicrobials is an important strategy to curb cariogenic microorganisms. AIM The aim was to evaluate the in vitro antimicrobial activity of C. sinensis extract on S. mutans and L. acidophilus. STUDY SETTING AND DESIGN ...
background: in the recent years, using health technologies to diagnose and treat diseases has had a considerable and accelerated growth. the proper use of these technologies may considerably help in the diagnosis and treatment of different diseases. on the other hand, unlimited and unrestricted entry of these technologies may result in induced demand by service providers. the aim of this study ...
, where E(x=La) is the erosion rate at the upstream end of the flow acceleration zone above a waterfall, Fr is the Froude number at this setting, and n ranges between 0.5–1.7. This amplification expression suggests that erosion at the lip could be as much as 2–5 times higher relative to erosion at a normal setting with identical hydraulic geometry. Utilizing this erosion amplification expressio...
Earlier studies have shown that plate gaps are sometimes unequal in two-zoned low consistency refiners and that unequal gaps render unevenly refined pulp. It is also known that optimisation of plate gap in low consistency refining leads to improved energy efficiency. In this work, trials were made in mill scale in a modern TMP line equipped with a prototype 72 inch TwinFlo low consistency refin...
