Sparganocosma docsturnerorum Brown, new genus and new species, is described and illustrated from Área de Conservación (ACG) in northwestern Costa Rica. The new genus shares a long, crescent- or ribbon-shaped signum in the corpus bursae of the female genitalia with Aesiocopa Zeller, 1877, Amorbia Clemens, 1860, Amorbimorpha Kruse, 2011, Coelostathma Clemens, 1860, Lambertiodes Diakonoff, 1959, P...
In order to study some theories about nonsuperconductivity of PrBa2Cu3O7, based on the density functional theory and with APW+lo/LAPW method some calculations for PrBa2Cu3O7 (Pr123) and YBa2Cu3O7 (Y123) were performed. The LSDA+U approximation was used for Pr(4f) orbitals and the effect of changing UPr on the band structure, Pr(4f)-DOS, distribution of electrons on the planes and chains, and ...
Background and Objectives: Breast cancer is the most common malignancy among women in the world. The aim of this study was to assess estrogen receptor (ER), progesterone receptor (PR) and HER-2/neu of infiltrating ductal carcinoma (IDC) with tumor size, histologic grade, lymph node metastasis and age. Methods: This study was carried out on 300 tissue blocks ofpatients with ID...
Doppler peaks extraction from massive raw data is a tricky part of coherent wind Lidar (CDWL) optimization. In this paper, hybrid genetic/Powell algorithm (HGAP) proposed to process the power spectrum measured signal CDWL. The HGAP has excellent global exploration capability, which likes traditional genetic algorithms and fast convergence, like Powell method. Hence, advantages find center frequ...
طی بیست سال گذشته, محققان, رابطه بین ایمان مذهبی و سلامت جسمی و روانی را مورد بررسی قرار داده اند (koening, 1999; koenig, mccullough, & larson, 2000; larson, swyers, & mccullough, 1998; levin, 1994; thoresen, 1999; همچنین بنگرید از همین جلد به mccullough, chapter3; plante & sharma, ; and thoresen, harris, & oman, chapter2). داده های بسیار حاصل از این پژوهش ها, رابطه مثبتی را نشان می دهد. هرچند ...
martin powell suggests that the death of the english national health service (nhs) has been announced so many times we are at risk of not noticing should it actually happen. he is right. if we ‘cry wolf’ too many times, we risk losing sight of what is important about the nhs and why.
