Excitons in thin layers of semiconducting transition metal dichalcogenides are highly subject to the strongly modified Coulomb electron-hole interaction these materials. Therefore, they do not follow model system a two-dimensional hydrogen atom. We investigate experimentally and theoretically excitonic properties both monolayer (ML) bilayer (BL) MoSe$_2$ encapsulated hexagonal BN. The measured ...

Ribonucleotide reductase from Escherichia coli consists of two nonidentical subunits, proteins Bl and B2. Affinity chromatography resulted in a Bl preparation which appeared homogeneous during polyacrylamide gel electrophoresis and ultracentrifugation. The molecular weight was 160,000 by sedimentation equilibrium centrifugation using a partial specific volume of 0.706 ml per g at 4”. Protein Bl...

In this paper we investigate the propositional logic of standard algebras for Hájek’s Basic Fuzzy Logic BL in a language expanded with propositional constants for the idempotent elements delimiting the L-, G-, and Π-components of the algebra. We start from a fixed standard BL-algebra; introduce new propositional constants; present a suitable set of axioms; investigate completeness results; and ...

EBV-carrying human cell lines, depending on whether the cells are derived from Burkitt's lymphoma (BL) tumor biopsies or transformed by EBV in vitro, have different growth properties in vitro. In contrast, there are no clear differences between tamarin tumor lines and tamarin LCLs in vitro. Both types of tamarin cell lines could grow in agarose and formed colonies unlike human LCLs, althoug...

There are some evidences on involvement of ABL2 in a number of cancers, especially ABL2 overexpression was observed in Raji, a Burkitt's lymphoma (BL) cell line. Therefore ABL2 overexpression may be involved in pathogenesis of Burkitt's lymphoma. The aim of this study was to evaluate ABL2 significance in BL. For this purpose 20 formaldehyde fixed paraffin embedded blocks – 16BL and 4 normal lym...

background: we aimed to develop and evaluate outcomes of a blended learning (bl) program for nursing and midwifery education in iran. materials and methods: this was a participatory action research project. after designing bl website, providing technological infrastructures, and holding preparatory workshops, 22 blended courses were designed. bl method was implemented for one semester. students...

The aim of this study was to evaluate the feeding of Qizil fattening lambs with different levels of broiler litter (BL) on their weight gain, dry matter intake (DMI), nutrient digestibility, selected blood metabolites and husbandry economics. During an eight-weeks experimental period, 28 male lambs (an average of 42.21 ± 5.63 kg and ages of 7-8 months) were allocated randomly to one of four die...
