This paper investigates the dynamical processes throughwhich the Tibetan Plateau (TP) influences theEast Asian summer monsoon (EASM) within the framework of the moist static energy (MSE) budget, using both observations and atmospheric general circulation model (AGCM) simulations. The focus is on the most prominent feature of the EASM, the so-called meiyu–baiu (MB), which is characterized by a w...

Studies of cardiac muscle energetics have traditionally used contraction protocols with strain patterns that bear little resemblance to those observed in vivo. This study aimed to develop a realistic strain protocol, based on published in situ measurements of contracting papillary muscles, for use with isolated preparations. The protocol included the three phases observed in intact papillary mu...

Combining the FH entropy of mixing and the standard RS enthalpy of mixing yields the FH solution theory for polymers: ∆G N = Bφ1φ2 + RT (φ1 lnφ1 + φ2 N lnφ2). As written above, this equation is comparable to the free energy of mixing from the Regular Solution Model. Notice that the expressions differ in two ways: first, FH is cast in volume fractions rather than mole fractions, and second, FH i...

A combined experimental and Density functional theory (DFT) B3LYP/6-311+G* study on the IR spectra of four stable isomers of 2-N,N-dimethylaminecyclohexyl 1-N’,N’-dimethylcarbamate was performed. Our theoretical calculations reveal that two new isomers of this compound exist and may be more stable than the known isomers. In addition the entropy, heat capacity, and the enthalpy content of the st...

Standard thermodynamic function changes (AGO”, AHe’, A&” and Acre”) are reported for proton dissociation of acridinium cation in aqueous solution. These values have been determined from a series of precise and accurate acid equilibrium constants, K,. The equilibrium constants have been obtained spectrophotometrically over a range of temperatures from 2 to 66°C at several ionic strengths (I = 0....

In this paper most significant thermodynamic parameters of R125, based on the propenles data presented in [1, 2]. will be examined and compared with those one of RS02. In fact, after the UNEP ~ontreal Protocol, at the present time the manufacturers and researchers have selected R1 25 as more probable long term substitute of R502 in refrigerating vapor compression plants operating with cold ambi...

Differential scanning calorimetry and X-ray diffraction of anhydrous and hydrated N-palmitoylgalactosylsphingosine (NPGS) show evidence of complex polymorphic behavior and interconversions between stable and metastable structural forms. Anhydrous NPGS exhibits three lamellar crystal forms (A, B, and B') at temperatures below 143 degrees C and a liquid-crystal form between 143 and 180 degrees C ...

Component A3 of the methylcoenzyme M methylreductase system of Methanobacterium thermoautotrophicum (strain delta H) has been resolved into two fractions. One, named component A3a, was defined as the fraction required along with components A2 and C to produce methane from 2-(methylthio)ethanesulfonate when titanium(III) citrate was used as the sole source of electrons. The second one, named com...

The 32-residue leucine zipper subsequence, called here Jun-lz, associates in benign media to form a parallel two-stranded coiled coil. Studies are reported of its thermal unfolding/folding transition by circular dichroism (CD) on samples of natural isotopic abundance and by both equilibrium and spin inversion transfer (SIT) nuclear magnetic resonance (NMR) on samples labeled at the leucine-18 a...

antioxidants are compounds which can prevent biological and chemical substances from oxidative damage by reactive oxygen species. flavonoids are the most important class of polyphenolic compounds that because of their antioxidant characters possess biological activities and pharmacological effects. chrysin-6-c-fucopyranoside and chrysin-3-malonyl-6-c-fucopyranoside are mono c-glycosyl derivativ...
