Bioadhesive polymers are natural or synthetic materials that can be used for soft tissue repair. The aim of this investigation was to develop an injectable, bioadhesive hydrogel with the potential to serve as a synthetic replacement for the nucleus pulposus of the intervertebral disc or as an annulus closure material. Branched copolymers of poly(N-isopropylacrylamide) (PNIPAAm) and poly(ethylen...

the benefits of using mineral admixtures as a partial replacement of portland cement (pc) are well established in the literature. economic and environmental advantages by reducing co2 emissions are well known. this paper examines the influence of intergrinding and separate grinding on the amount of energy consumption, blaine fineness and particle size distribution (psd) of blended cements, name...

Poly(ethylene-co-propylene-co-diene) (EPDM) containing 50 wt% of poly(ethylene-co-propylene) grafted with maleic anhydride (EP-g-MA) has been melt blended with poly(styrene-co-acrylonitrile) (SAN) added with various amounts of reactive SAN, i.e. SAN bearing either primary amine (SAN-NH2) or carbamate groups (SAN-carb). Carbamate groups are precursors of primary amines by thermal thermolysis dur...

The phenolic amines include substances such as epinephrine, norepinephrine, and serotonin, whose physiological importance has been known for many years, and some other amines of recent interest whose biological significance is less clear; these include dopamine (1) and octopamine (2). It is probable that still others exist and have a physiological function in some tissues of the body. The conce...

This paper is a report of a study to examine the influence of demographic, learning involvement and learning performance variables on metacognition of undergraduate nursing students in a blended learning environment. A cross-sectional, correlational survey design was adopted. Ninety-nine students invited to participate in the study were enrolled in a professional nursing ethics course at a publ...

BACKGROUND Nurses are experiencing new ethical issues because of global developments and changes in the healthcare environment. Blended learning is one of the various methods used to deliver meaningful learning experiences. Well-designed, properly administered nursing ethics education is essential for nursing students to visualize the role of professional nurses. However, a literature review sh...
