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...

in this paper, we introduce the notion of multiplier in -algebra and study relationships between multipliers and some special mappings, likeness closure operators, homomorphisms and ( -derivations in -algebras. we introduce the concept of idempotent multipliers in bl-algebra and weak congruence and obtain an interconnection between idempotent multipliers and weak congruences. also, we introduce...

Purpose. The aim of the study was to compare the risk of thyroid malignancy and efficacy of repeat FNA in patients with thyroid nodules diagnosed cytologically as benign lesion (BL) with features of chronic thyroiditis (BL-CT) and BL without CT features (BL-nCT). Methods. The analysis included 917 patients with BL-CT and 7046 with BL-nCT in the first FNA. Repeat biopsy was carried out in 787 pa...

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...

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...

We show that if a Lie group acts properly on a co-oriented contact manifold preserving the contact structure then the contact quotient is topologically a stratified space (in the sense that a neighborhood of a point in the quotient is a product of a disk with a cone on a stratified space). As a corollary we obtain that symplectic quotients for proper Hamiltonian actions are topologically strati...

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, althou...

Lymphocyte function-associated antigens 1 and 3 (LFA-1, LFA-3) and intercellular adhesion molecule 1 (ICAM-1) are cell surface adhesion molecules necessary for immune processes requiring intercellular contact. It was recently proposed that malignant Burkitt's lymphoma cells (BL) may escape from immunosurveillance through the downregulation of LFA-1 (CD11a/CD18) or LFA-3 (CD58) and ICAM-1 (CD54)...

In this note, we define the concepts of admissible relation and admissible partition for an arbitrary BL-general fuzzy automaton.In particular, a connection between the admissible partition and the quotient BL-general fuzzy automaton is presented.It is shown that if we use the maximal admissible partition, then we obtain a quotient BL-general fuzzy automaton and this quotient is minimal. Finall...
