The enhancement of surface wettability by hydrophilic polymer coatings has been great interest because it used to address several technical challenges such as biofouling and fogging. Among the polymers, zwitterionic polymers have extensively utilized coat solid surfaces due their excellent capability bind water molecules, thereby forming dense hydration layers on surfaces. For these function appropriately surfaces, techniques for fixing onto with high efficiency are required. Herein, we...

Chúng tôi báo cáo một trường hợp đồng mắc bạch cầu cấp dòng tủy (acute myeloid leukemia - AML) và u lympho không Hodgkin tế bào T. Đây là hai bệnh máu ác tính hiếm gặp ở cùng nhân (BN). Quá trình chẩn đoán đưa ra phương án điều trị nhiều khó khăn. Ban đầu, BN được mạn giai đoạn tăng tốc, BCR-ABL p210 dương tính, đã bằng imatinib các chỉ số cải thiện nhưng hạch vẫn to. sinh thiết nhuộm HE hóa mô miễn dịch cho kết quả Sau đó, phác đồ 3+7, củng cố HiDAC 3 chu kỳ đánh giá đạt lui hoàn toàn về...
Abstract The control of biofouling, which is the unwanted adsorption biomolecules and organisms on solid surfaces, a prerequisite for wider applicability functional materials that are currently being used in biomedical industries. One frequently methods controlling biofouling use surface coatings with antifouling materials. Herein, fucoidan, marine‐derived polysaccharide, reported as new type material safe broadly applicable. Fucoidan conjugated catechols, known to act adhesives grafting...
The structural characteristics of membrane support directly affect the performance carrier facilitated transport membrane. A highly porous PolyHIPE impregnated with Aliquat 336 is proposed for Cr(VI) separation. consisting poly(styrene-co-2-ethylhexyl acrylate) copolymer crosslinked divinylbenzene has pore structure characteristic large spaces interconnected small window throats. unique provides high flux and stability. experimental results indicate that effective diffusion coefficient D*...
Objectives: The COVID-19 pandemic has significantly impacted individual health, potentially increasing the demand for home medicine storage. However, inappropriate household storage can lead to drug waste and unnecessary hazards. This study aimed explore prevalence of identify factors that predict in Vietnamese households. Methods: A community-based cross-sectional was conducted with 800 households Danang, Vietnam. multi-stage sampling method applied this study. data collection tool modified...
In this paper, we study the formation of optical bistability (OB) and multistability (OM) in a degenerate four-level atomic system by an external magnetic field that is excited probe laser field, coupling signal field. The can cause electromagnetically induced transparency (EIT) for medium, while and/or switch between single-EIT two-EIT regimes. Based on these properties, OB OM effects be formed at two different frequency regions (two channels). By adjusting or intensity fields, threshold...
Abstract Catechol and/or pyrogallol groups are recognized as crucial for the formation of polyphenol coatings on various substrates. Meanwhile, studies polyphenolic molecules that do not contain such relatively rare. The key molecule in turmeric‐based universal (i.e., substrate‐independent) is curcumin, which contains no catechol or groups. As chemically reactive hydroxyl would remain after curcumin coating, it hypothesized coating can serve a layer controlling interfacial properties. In...
We prove the existence and upper semicontinuity with respect to nonlinearity diffusion coefficient of global attractors for a class semilinear degenerate parabolic equations in an arbitrary domain.
A method for the simultaneous determination of seven B-group vitamers including thiamine, riboflavin, nicotinamide, niacin, pyridoxine, pyridoxal, and pyridoxamine in nutritional products by using enzymatic digestion followed LC-MS/MS quantification was studied. The conditions such as MS transitions, mobile phase programs, ammonium formate buffer concentrations, sample treatment procedures (e.g., concentrations solution, temperature, time) were investigated. analytical performance evaluated...
Abstract Considered here is the pullback attractor of process associated with first initial boundary value problem for non-autonomous semilinear degenerate parabolic equation \begin{linenomath} u_t-\text{div}(\sigma(x)\nabla u)+f(u)=g(x,t) \end{linenomath} in a bounded domain Ω ℝ N (N≥2). We prove regularity space L 2 p −2 (Ω)∩ $D_0^2(\Omega,\sigma)$ , and estimate fractal dimension (Ω).
In this paper, we consider a class of nonclassical diffusion equations on with hereditary memory, in presence singularly oscillating external forces depending positive parameter ε and new nonlinearities, which have no restriction the upper growth nonlinearity. Under general assumption memory kernel κ for very large prove existence uniform attractors . The boundedness (w.r.t. ) convergence as tends to 0 are also studied. Our results extend improve some Anh Toan.
In this article, integrated radial basis functions (IRBFs) are used for Hermite interpolation in the solution of differential equations, resulting a new meshless symmetric RBF method. Both global and local approximation‐based schemes derived. For latter, focus is on construction compact approximation stencils, where sparse system matrix high‐order accuracy can be achieved together. Cartesian‐grid‐based stencils possible problems defined nonrectangular domains. Furthermore, effects width...
This article reports a new numerical procedure, which is based on integrated radial basis functions (IRBFs) and Cartesian grids, for solving time-dependent differential problems that can be defined non-rectangular domains. For space discretizations, compact five-point IRBF stencils are utilized. time two-point scheme proposed, where the derivative approximated in terms of not only nodal function values at current previous levels but also level. allows other than linear one to captured well...
