Cavity ring-down spectroscopy (CRDS) has allowed for increasingly widespread, in situ observations of trace gases, including the stable isotopic composition of water vapor. However, gathering observations in harsh environments still poses challenges,

Ground improvement by grouting is one of the methods applicable to solve problems connected to foundations, open cut excavations and tunnelling. The improvement of soils is in terms of reduced permeability and increased strength. It has traditionally

We tested the hypothesis whether the number of applied load cycles and the frequency of uniaxial strain have an effect on proliferation of human bone derived osteoblast-like cells. A new approach was developed in order to differentiate between the ef

Should Licensure be Required for Faculty Who Teach Direct Practice Courses? No!

Autor: Fredrick W. Seidl

Publikováno v: Journal of Social Work Education. 36:193-197

The enactment of a standard requiring licensure for teachers of practice courses would be impractical and unfair. It would be redundant since adequate measures of academic accountability are already in place, and unnecessary since teaching is not the

Effects of physiologic dynamic strain on human osteoblasts

Autor: Anita Ignatius, Daniela Kaspar, Lutz Claes, W. Seidl, Cornelia Neidlinger-Wilke

Publikováno v: Der Orthopäde. 29:0085-0090

The cell activity of human bone derived cell cultures was studied after mechanical stimulation by cyclic strain at a magnitude occurring in physiologically loaded bone tissue. Monolayers of subconfluently grown human bone derived cells were stretched
