در این آزمایش 14 سویه ازتوباکتر کروکوکوم جداسازی شده از مزارع گندم اطراف تبریز از نظر توان تولید سیدروفور در شرایط درون شیشهای با استفاده از محیط کشت جامد حاوی کرومآزرول-اس مورد ارزیابی قرار گرفتند که برخی از سویههای مورد بررسی از توان تولید سیدروفور نسبتاً بالائی برخوردار بودند. سپس با استفاده از خاک سترون در یک آزمایش گلخانهای با گیاه گندم بهاره رقم فلات در قالب طرح کاملاً تصادفی با 16 تیما...
Cognitive Architectures (CAs) are the core of artificial cognitive systems. A CA is supposed to specify the human brain at a level of abstraction suitable for explaining how it achieves the functions of the mind. Over the years a number of distinct CAs have been proposed by different authors and their limitations and potentials were investigated. These CAs are usually classified as symbolic and...
based on the convolutional model, a seismic trace is the convolution of seismic source wavelet and reflection coefficient series of the earth. seismic source wavelet estimation is one of the most important stages in processing and interpretation of seismic data. accurate estimation of wavelet increases the efficiency of the deconvolution and temporal resolution of seismic data. on the other han...
Carbonic anhydrases (CAs) are metalloenzymes that are omnipresent in nature. CAs catalyze the basic reaction of the reversible hydration of CO₂ to HCO₃- and H⁺ in all living organisms. Photosynthetic organisms contain six evolutionarily different classes of CAs, which are namely: α-CAs, β-CAs, γ-CAs, δ-CAs, ζ-CAs, and θ-CAs. Many of the photosynthetic organisms contain multiple isoforms of each...
Les sacro-iliites infectieuses méritent d'être mieux connues. Leur diagnostic est souvent retardé en raison d'une symptomatologie trompeuse et des diffcultés d'exploration de l'articulation sacro-iliaque. Notre travail est basé sur une étude rétrospective portant sur les cas de SII, recueillis sur une période comprise entre 1997 et 2008 dans notre centre universitaire Sfax-Tunisie. Le diagnosti...
introduction: wavelet transform is one of the useful and suitable tools for time series and signal analysis. nowadays wavelet transform is frequently used in geophysical data processing and interpretation, especially seismic data. however, the use of this method isn’t widespread in gravity and geomagnetic. fedi and quarta (1998), martelet et al. (2001) and de oliveira lyrio (2004) used the wave...
OBJECTIVES The purpose of this study was to evaluate and compare outcomes of patients undergoing carotid artery stenting (CAS) for ipsilateral restenosis, after either previous CAS or carotid artery endarterectomy (CEA) (CAS-R group), with those of patients who had CAS performed for de novo carotid atherosclerotic stenosis (CAS-DN group). BACKGROUND Therapeutic revascularization strategies to...

This paper describes a research whose main focus is the use of Computer Algebra Systems (CAS) in mathematical classrooms and the didactical possibilities linked with its use. The possibilities of integrating Self-Regulated Learning (SRL) within the CAS environment are brought into focus. Forty-three Israeli students (mean age 13.3) were assigned to two learning algebraic groups. The first group...
Background: To evaluate the association between pre/post-procedural high sensitive C-reactive protein (hs-CRP) level and hs-CRP difference, and the risk of major adverse cardiovascular events (MACE) or new diffusion-weighted MRI lesions after carotid angioplasty and stenting (CAS). Methods: In this study, conducted in 2016 in Shiraz (Iran), patients who underwent diagnostic angiography and CAS...
