background: leukoaraiosis (la) or white matter thinning and rarefaction are common in stroke patients. this pilot double-center study was designed to evaluate la risk factors in stroke patients. methods: this cross sectional study was conducted on 100 consecutive stroke patients in walter mackenzie hospital, canada and 100 consecutive stroke patients in valie-asr hospital , iran in 2004. diag...
Background and Objective: In order to ethically supervise laboratory animal (LA) researches, various regulatory structures (RS) are developed in many countries. Our primary hypothesis was that these RS are not well developed in Iran, therefore, we aimed to propose the principles of developing these RS in our country, based on scientific principles and religious morals. Materials and Meth...
Tree basal area (ba) or diameter at breast height (dbh) are universally used to represent tree secondary growth in individual tree based growth models. However, the long-term implications of using either ba or dbh for predictions are rarely fully assessed. In this analysis, Dba and Ddbh increment equations were fit to identical datasets gathered from six conifer and four hardwood species grown ...
Quartet n-d scattering lengths are calculated using second-generation nucleon-nucleon potential models. These results are compared to the corresponding quantity recently calculated using chiral perturbation theory. 1 Accurate calculations of n-d quartet scattering lengths were first performed 10 years ago[1]. This quantity is known to be insensitive to most physics, such as ℓ > 0 partial waves ...
Background: Fine needle aspiration biopsy (FNAB) is usually used to distinguish the malignant and benign nodules. Applying a biopsy needle evokes a sense of fear and pain in the patients. Although some studies refute the usefulness of local anesthesia (LA) prior to fine needle aspiration biopsy, it is still debatable. This prospective cross-sectional study intended to evaluate the effect of LA ...
a lépoque classique, on affirmait que la peinture est une poésie muette, la poésie une peinture parlante. de fait, les relations entre littérature et peinture se sont développées tout au long des siècles dans une constante émulation. dans ce mémoire, nous explorons le dialogue fécond de ces deux arts au début du xxe siècle. lart et la poésie, à laube du xxe siècle, montrent la rupture avec le m...
A useful nanophotocatalyst (La,S-TiO2) was prepared by a sol-gel method and characterized by UV–vis diffuse reflectance spectroscopy (DRS), X-ray diffraction (XRD), photoluminescence emission spectroscopy (PL) and scanning electron microscopy (FESEM). The results showed that the La,S-TiO2, which calcined at 550 °C, contained only anatase phaseand its crystal size was 23 nm...
This study was conducted to determine optimal ratios of dietary linolenic acid (18:3n-3, LnA) to linoleic acid (18:2n-6, LA) for Tor tambroides. Juveniles were fed three trial diets with different ratios of LnA/LA (0.0, 0.5 and 1.0) for 10 weeks. Another diet contained 100% palm oil, which was similar tothe diet with 0.0 LnA/LA ratio but different in total amounts of C18polyunsaturated fatty ac...
selon les pédagogues, la culture étant un élément très important dans le processus de lapprentissage de langue étrangère et la maîtrise de la compétence linguistique requiert celle de la compétence culturelle. la littérature dun pays est comme un miroir qui reflète bon nombre daspects culturels, cest pourquoi avec le choix dun texte littéraire convenable, lenseignant peut assurer à la fois lapp...
