The main aim of this study was to investigate the effect of different coating materials (i.e. Na-alginate and chitosan) on the viability and release behavior of Bifidobacterium pseudocatenulatum G4 in the simulated gastric fluid (SGF) and simulated intestinal fluid (SIF). This study reports the viability of encapsulated B. pseudocatenulatum G4 coated using different alginate (2-4 g/100mL) and c...
and Applied Analysis 3 Example 1.4. Let X, ‖ · ‖ be a normed space, a ∗ b ab, and a b min{a b, 1} for all a, b ∈ 0, 1 . For all x ∈ X and every t > 0, consider μ x, t ⎧ ⎪⎨ ⎪⎩ t t ‖x‖ if t > 0, 0 if t ≤ 0; ν x, t ⎧ ⎪⎨ ⎪⎩ ‖x‖ t |x| if t > 0, 1 if t ≤ 0. 1.1 Then X, μ, ν, ∗, is an IFNS. Remark 1.5 see 3 . Let X, μ, ν, ∗, be an IFNS with the condition μ x, t > 0, ν x, t < 1 implies x 0 ∀t ∈ . 1.2 L...
Background Research predicting the public health and fiscal impact of Supervised Injection Facilities (SIFs), across different cities in Canada, has reported positive results on the reduction of HIV cases among People Who Inject Drugs (PWID). Most of the existing studies have focused on the outcomes of Insite, located in the Vancouver Downtown Eastside (DTES). Previous attention has not been af...
This paper conducts a numerical analysis on the external surface cracked steel pipes reinforced with Composite Repair System. A three-dimensional finite element (FE) model is developed to calculate Stress Intensity Factor (SIF) of crack, and crack growth process evaluated by Paris’ law. The effect FRP-to-steel interfacial bond condition SIF evaluation has been considered incorporating cohesive ...
پالسارها، ستاره های نوترونی چرخان بسیار مغناطیده هستند. شواهد مشاهداتی نشان می دهد که میدان مغناطیسی در پالسارها با گذشت زمان کاهش می یابد. در ابتدا به بررسی مختصری از خصوصیات کلی پالسارها می پردازیم. سپس دو مدل تحول میدان مغناطیسی، تحت عنوان مدل استهلاک اهمی و مدل تضعیف میدان در اثر کاهش اسپین (sif) ، را معرفی می کنیم. با در نظر گرفتن مدل های ارائه شده و محاسبات عددی، تحول میدان مغناطیسی در پا...
The parameterization of key photosynthesis parameters is one the uncertain sources in modeling ecosystem gross primary productivity (GPP). Solar-induced chlorophyll fluorescence (SIF) offers a good proxy for GPP since it marks actual process photosynthesis; while machine learning (ML) provides robust approach to model GPP-SIF relationship. Here, we trained boosted regressing tree (BRT) and Rand...
UNLABELLED The aims of this study were to determine whether body weight or body surface area (BSA) should be used for noninvasive measurement of the cerebral metabolic rate of glucose (CMRGlc) by FDG PET with a standardized input function (SIF) and an autoradiographic method and to validate the procedure in a large population from different PET centers. METHODS Plasma input functions measured...
Verhofstad et al. (Verhofstad, A. A. J., H. W. M. Steinbusch, B. Penke J. Varga, and H. W. J. Joosten (1981) Brain Res. 212: 39-49) have reported that serotonin of the rat superior cervical ganglion is contained in a distinct and separate population of small intensely fluorescent (SIF) cells. We provide evidence that the serotonin-containing SIF cells are modulated, in part, by preganglionic ch...
Purpose To determine if skin intrinsic fluorescence (SIF), a noninvasive measure of advanced glycation endproducts and oxidative stress in skin is associated with AMD. Methods SIF was measured with the SCOUT DS skin fluorescence spectrometer in a cross-sectional cohort study of 969 persons aged 68 to 102 years from the 1181 who participated in the 25-year follow-up examination in the Beaver D...
