Using 2.45x10;{7} psi(2S) decays collected with the CLEO-c detector at the Cornell Electron Storage Ring we present the most precise measurements of magnetic dipole transitions in the charmonium system. We measure B(psi(2S)-->gammaeta_{c})=(4.32+/-0.16+/-0.60)x10;{-3}, B(J/psi-->gammaeta_{c})/B(psi(2S)-->gammaeta_{c})=4.59+/-0.23+/-0.64, and B(J/psi-->gammaeta_{c})=(1.98+/-0.09+/-0.30)%. We obs...
It has been indicated that photosystem I (PSI) is susceptible to chilling-light stress in tobacco leaves, but the effect of growth light intensity on chilling-induced PSI photoinhibition in tobacco is unclear. We examined the effects of chilling temperature (4°C) associated with moderate light intensity (300 μmol photons m(-2) s(-1)) on the activities of PSI and photosystem II (PSII) in leaves ...
We developed a novel method for the isolation of the PSI-LHCI-LHCII complex from spinach leaves. The supercomplex was resolved into a core complex (CPI), LHCII trimers, LHCI dimers and LHCII monomers using green gel electrophoresis. We then investigate changes in the fluorescence and absorption spectra of PSI-LHCI-LHCII under high light. In addition, we compared light-induced denaturation of th...
The yeast Sup35 and Rnq1 proteins can exist in either the noninfectious soluble forms, [psi-] or [pin-], respectively, or the multiple infectious amyloid-like forms called [PSI+] or [PIN+] prion variants (or prion strains). It was previously shown that [PSI+] and [PIN+] prions enhance one another's de novo appearance. Here we show that specific prion variants of [PSI+] and [PIN+] disrupt each o...
Efficient mass transport through porous networks is essential for achieving rapid response times in sensing applications utilizing porous materials. In this work, we show that open-ended porous membranes can overcome diffusion challenges experienced by closed-ended porous materials in a microfluidic environment. A theoretical model including both transport and reaction kinetics is employed to s...
ϩ ] (Wickner, 2001). [PSI ϩ ] is hereditary by classical Cambridge, Massachusetts 02142 genetic criteria—[PSI ϩ ] is transmitted from parents to their progeny both in somatic divisions (mitosis) and in Transformation continues to provide the most compelling evidence that DNA is genetic material. A purified sexual divisions (meiosis). A cross of [PSI ϩ ] by [psi Ϫ ] results in all [PSI ϩ ]progen...
اثربخشی آموزش مهارتهای والدگری بر پیشگیری تنیدگی در یک نمونه غیربالینی از مادران و کاهش مشکلات رفتاری کودکان آنها در این پژوهش بررسی شد. شاخص تنیدگی والدین (psi ، آبیدین، 1990) در یک نمونه 198 نفری از مادران اجـرا شد. 51 نفر از مادرانی که نمره هـای بالایی در psi داشتند به تصادف در دو گروه آزمایشی (26 نفر) و کنترل (25 نفر) قرار گرفتند و به فهرست مشکلات رفتاری کودکان (cbcl، آشنبـاخ، 2001) پـاسخ د...
We present a short review of recent progress in the field of optical gas sensors based on porous silicon (PSi) and PSi composites, which are separate from PSi optochemical and biological sensors for a liquid medium. Different periodical and nonperiodical PSi photonic structures (bares, modified by functional groups or infiltrated with sensory polymers) are described for gas sensing with an emph...
