high nitrogen and plant density cause increasing vegetative growth and reducing harvest index. the objective of this study was to evaluate the effect of cycocel at high nitrogen and plant density on safflower yield and yield components. for this purpose a field experiment was carried out as a factorial-split plot based on randomized complete block design with three replications with esfahan 14 ...

OBJECTIVE The aims were to validate the use of a direct reading NO electrode, to compare the effects of diverse acting drugs on altering coronary flow (CF) and NO release, and to examine the effects of altered perfusion pressure on flow-induced changes in NO concentration [NO] in the hemoglobin free effluent of guinea pig isolated hearts. METHODS Hearts were isolated and perfused initially at...

In orderto determine the incidence ofallergic bronchopulmonary aspei llosis (ABPA) in patients with cyslic fibrosis (CF), we reviewed the records of 236 patients followed up at the Duke CF Center. Sixty patients (25 percent) had colonies ofAspergiliusjismigatus. Thesepafients were older and had more severe disease as assessed by lower Shwachman-Kulczycld (S-K) scores than the patients who did n...

Persian language is one of the most widely used languages in the Web environment. Hence, the Persian Web includes invaluable information that is required to be retrieved effectively. Similar to other languages, ranking algorithms for the Persian Web content, deal with different challenges, such as applicability issues in real-world situations as well as the lack of user modeling. CF-Rank, as a ...

BACKGROUND More than 40% of people born with cystic fibrosis (CF) now reach adulthood. Greater attention is being focused on improving their health-related quality of life (HRQoL). While markers of disease severity such as lung function are only modestly associated with HRQoL, in other chronic illnesses depression is an important correlate. The objective of this study was to evaluate the relati...

Zirconium complexes with enolatoimine ligands bearing an electron-withdrawing trifluoromethyl group on the alkoxy moiety [κ²-N,O-{2,6-R₂N=C(CH₃)C(H)=C(O)CF₃]₂ZrCl₂ (2a, R = H; 2b, R = F; 2c, R = CH₃; 2d, R = (i)Pr) were prepared. The isopropyl substituents hinder rotation in solution for 2d, and result in a trans-arrangement of the N-donors in the solid state. Catalyst activities are similar fo...

this experiment was conducted to improve the nutritive value of barley stubble for two consecutive years. after harvesting crop, at first year, a completely randomized design, with a 3 × 3 factorial experiment was conducted in which 27 plots were divided into nine treatments. the treatments including zero, 2.5 and five percent urea each with zero, three and six percent molasses were mixed with ...

Twelve pregnant, multiparous sows were assigned during gestation to three dietary treatments in a 3 x 3 Latin square design to evaluate the effect of increasing levels of crude fiber (CF): a conventional diet low in CF (L, 15.8 MJ DE/kg of DM, 3.3% CF), a diet with a medium level of CF (M, 14.4 MJ DE/kg of DM, 10.6% CF), and a high-fiber diet (H, 12.9 MJ DE/kg of DM, 18.1% CF). The daily feed s...

C igarette smoking is a major risk factor in the development of pulmonary emphysema, a chronic disorder thought to be caused by excess protease activity in lung. Although inhalation of cigarette smoke is associated with accumulation of polymorphonuclear leukocytes (PMN; a major source of preformed proteases) in the lung, cigarette smoke, by itself, is not chemotactic for PMN. Since alveolar mac...
