1. In a recent paper [4], Sevrin has given necessary and sufficient conditions for a subsemigroup of the free product of a free group and a free semigroup to be of the same form; in particular he deduces that a subsemigroup T oí a free semigroup 5 is free if and only if1 1. For any aET, sES, if as ET and saET, then sET. Now whereas the property of being a free subsemigroup of S is absolute, i.e...

The thermodynamics of folding and unfolding of a beta-heptapeptide in methanol solution has been studied at four different temperatures, 298 K, 340 K, 350 K, and 360 K, by molecular dynamics simulation. At each of these temperatures, the 50-ns simulations were sufficient to generate an equilibrium distribution between a relatively small number of conformations (approximately 10(2)), showing tha...

In this paper, we employ mimetic $f(R,T)$ gravity coupled with Lagrange multiplier and potential to yield viable inflationary cosmological solutions consistent latest Planck BICEP2/Keck Array data. We present here three of the Hubble parameter ($H$) represented by $H(N)=\left(A \exp \beta N+B \alpha ^N\right)^{\gamma }$, ^N+B \log N\right)^{\gamma e^{\beta N}+B where $A$, $\beta$, $B$, $\alpha$...

We describe a first attempt to study the antibody-combining sites recognized by monoclonal antibodies raised against the beta-subunit of human choriogonadotropin (hCG). Two groups of antibodies were first defined by their ability to recognize only the free beta-subunit or the free and combined subunit. Antibodies FBT-11 and FBT-11-L bind only to hCG beta-subunit but not to hCG, whereas antibodi...

OBJECTIVES To examine the clinical utility of the first-trimester markers of aneuploidy in their ability to predict future fetal loss. METHODS We examined 54,722 singleton pregnancies with no chromosomal abnormality and with complete outcome data that had undergone screening for trisomy 21 by a combination of fetal nuchal translucency (NT) thickness, maternal serum free beta-human chorionic g...

Effect of various cooking methods on antioxidant content and radical scavenging activity of pumpkin was evaluated. Pumpkin (Cucurbita moschata) was boiled and stir-fried for 2, 4 and 6 minutes respectively. Beta-carotene and lycopene were determined using HPLC and total phenolics measured using Folin-Ciocalteu method. The free radical scavenging activity of the samples was determined using 1, 1...

OBJECTIVE High circulating free fatty acids, commonly associated with obesity and insulin resistance, impair structure and function of the microvasculature. However, the mechanisms by which fatty acids cause microvascular remodeling are unclear. Using the mesangial cell model of microvascular pericytes, we demonstrate that the monounsaturated free fatty acid oleate induces a myofibroblast pheno...

The biologically active compounds, antioxidant activities, and free radical scavenging effects of black mussel dry matter (Mytilus galloprovincialis)--(BMDM) were investigated. The extract from BMDM with absolute methanol (BMDMAMet) showed the strongest inhibition of lipid peroxidation as a function of its concentration, and was comparable to the antioxidant activity of butylated hydroxyanisole...

Dunalia spinosa, a plant used in folk medicine for toothaches, breathing problems and cleansing wounds, was found active as antimicrobial and antioxidant. A new (E)-aurone rutinoside (dunaurone) has been isolated from the aerial parts of the plant, and its structure was determined by spectroscopic means. Lupeol, beta-sitosterol, scopoletin, quercetin and withaferin A were also found. All the ex...

We study the complexity of approximating partition function $Z_{\mathrm{Ising}}(G; \beta)$ Ising model in terms relation between edge interaction $\beta$ and a parameter $\Delta$ which is an upper bound on maximum degree input graph $G$. Following recent trends both statistical physics algorithmic research, we allow to be any complex number. Many results focus parameters, because physical relev...
