Thermally induced phase separation (TIPS) and thermal imidization were used to prepare PI-based monoliths in sequence. The hybridized PI (PI-co-POSS) exhibit potential liquid diode application achieve oil–water separation.
The performance of D-STATCOM depends on capacitor voltage regulation. In D-STATCOM, the nonlinear controller is preferred to linear controller. Regulating and fixing the capacitor DC voltage in DSTATCOM can improve the system dynamic such as capacitor voltage response, current response and modulation index. The regulation of DC capacitor voltage based on optimal PI co-efficient. In conventional...
Autonomous Control Modes and Optimized Path Guidance for Shipboard Landing in High Sea States Progress Report (CDRL A001) Progress Report for Period: April 10, 2015 to July 9, 2015 PI: Joseph F. Horn 814-865-6434 [email protected] Penn State University Co-PI: John Tritschler (301) 995-1637 [email protected] U.S. Naval Test Pilot School Co-PI: Chengjian He (408) 523-5100 [email protected] Ad...
The homeostasis of Pi in marine teleosts is maintained by renal Pi secretion as well as by Pi reabsorption. A Na/Pi co-transport system belonging to the NaPi-II protein family is instrumental in tightly controlled renal Pi handling in mammals and fish. We have isolated an NaPi-II related cDNA from winter flounder. It was cloned from a female gonad cDNA library and is 624 bp long. The transcript...
Abstract The physical state of mesons can be mixed using the unitary matrix. decay processes \omega \rightarrow \pi^{+}\pi^{-} and \phi originate from isospin symmetry breaking. \rho-\omega , \rho-\phi \omega-\phi interferences lead to a resonance contribution produce strong phases. CP violation is considered breaking due new phase first order. enhanced greatly fo...
Grafting non-polar polymer chains on the surface of polar nanoparticles (e.g., silica) is an effective way to enhance particle/matrix interactions and thus promote their homogeneous dispersion within a matrix, which leads improved mechanical properties. Current grafting methods have not yet produced with well-defined polymers high density. Here, we employed anionic polymerization vacuum techniq...
β cell pseudoislets (PIs) are used for the in vitro study of β-cells in a three-dimensional (3-D) configuration. Current methods of PI induction require unique culture conditions and extensive mechanical manipulations. Here we report a novel co-culture system consisting of high passage β-cells and islet-derived endothelial cells (iECs) that results in a rapid and spontaneous formation of free-f...
Identification and characterization of the Na+/Pi co-transporter in the renal brush-border membrane (BBM) has proved to be difficult in part because of the lack of a specific covalent label. NAD is a competitive inhibitor of Na+/Pi co-transport, and we have explored its potential use as a specific label. We describe the synthesis and use of a highly reactive azido derivative of NAD. This deriva...
شاخص توپولوژیک عددی حقیقی است که به یک گراف نسبت داده می شود و تحت یک ریختی گراف ثابت می ماند. شاخص های توپولوژیک برای بررسی خواص فیزیکی-شیمیایی ترکیبات شیمیایی به کار می روند. شاخص pi در مقاله ای در سال 2009 در تلاش جهت یافتن رابطه ای دقیق برای محاسبه ی شاخص pi رأسی حاصل ضرب دکارتی گراف ها معرفی شد. بعدها کاربردهای فراوانی از این شاخص در علوم نانو و شیمی به دست آمد. مطالعه ی ریاضی ای...
The interphase properties in nanocomposites indicate the interaction between filler and matrix, which is dependent on preparation method, shape, size of chemical two phases. Local environment polymer matrix give rise to different dielectric compared that bulk material. These allow understanding their effects glass transition (Tg) nanocomposites. In this study, power law model was used predict b...
