abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
multiple sclerosis (ms) is a demyelinating neuro- inflammatory autoimmune disease of the central nervous system. genetic predisposition has long been suspected in the etiology of this disease. the association between mthfr polymorphisms and ms has been ivestigated in different ethnic groups. we investigated the association between mthfr c677t and a1298c missense variants and ms in 180 patients ...
BACKGROUND Salt intake was reported to be associated with increased clinical and MRI activity in adult patients with relapsing-remitting multiple sclerosis (MS). OBJECTIVE To determine if salt intake is associated with time to relapse in patients with paediatric-onset MS. METHODS Paediatric-onset MS and patients with clinically isolated syndrome (CIS) within 4 years of disease onset were re...
چکیده: در این تحقیق تأثیر ملاس که یکی از محصولات جانبی صنایع قند می باشد به عنوان یک افزودنی مقاومت خشک جدید در بهبود پالایش پذیری و ویژگی های فیزیکی و مکانیکی مقوای کنگره ای کهنه (occ) مورد بررسی قرار گرفته شد. بدین منظور پنج سطح ملاس( 0،5، 10، 15 و 18%) و سه سطح درجه روانی(420،400و320 میلی لیتر)به عنوان فاکتورهای متغیر در نظر گرفته شد و برای هر تیمار کاغذهای دست ساز با مساحت 2cm200 و وزن پای...
Since the fi rst generation of commercial ICP-MS appeared on the market in the 1980’s, the technique has been adopted for trace elemental analysis across a wide range of industries and applications. The measurement of high matrix samples typical of environmental, clinical, food, nuclear and geological applications, however, remains challenging. When high total dissolved solids (TDS) samples are...
the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
BACKGROUND AND PURPOSE Clinical MR imaging scanners now offer many choices of hardware configurations that were not available in the first 25 years of their existence. Our goal was to assess the influence of coil technology, magnetic field strength, and echo time (TE) on the sensitivity, reflected by the signal intensity-to-noise-ratio (SNR) and reproducibility of proton MR spectroscopy (1H-MR ...
St. John’s wort is a traditional medicinal plant that has been used from ancient time for the treatment of neurological and psychiatric diseases. A successful in vitro propagation system for the St. John’s wort was optimized. Different explant type (single node and stem cutting with two nodes) were used in Murashige and Skoog (MS) medium in different concentrations (MS full, 3/4 MS and 2/3 MS)...
Pesticide residues and heavy metal concentrations were determined in two depths (0–20 20–40 cm) of Chromic Cambisol 69 vineyards the Slovenian winegrowing region Karst. Similarly, pesticide also Calcaric 11 other Croatian regions Istria. The topsoil was analysed for presence 176 different pesticidal active substances using multiresidue analytical methods: (a) gas chromatography coupled with mas...
