scientific communications network is presented in, sociology of science. and we can use steven's evaluative bibliometrics to map it. in citation network approach, scientist's communication behavior is predicted through their citation behavior. in this paper, first, concepts such as sociology of science, scientific community, scientific communications and its kinds are described. two k...

Sea cucumber is a health-beneficial food, and contains a variety of physiologically active substances including glycosphingolipids. We show here the sphingoid base composition of cerebrosides prepared from sea cucumber and the cytotoxicity against human colon cancer cell lines. The composition of sphingoid bases prepared from sea cucumber was different from that of mammals, and the major consti...

Optical frequency combs can potentially provide an efficient light source for multi-terabit-per-second optical superchannels. However, as the bandwidth of these multi-wavelength sources is increased, it result in low per-line power. amplifiers be used to overcome power limitations, but accompanying spontaneous noise degrade performance systems. To this, we demonstrate wideband reduction comb li...

In spite of almost two decades of experience, Strategic Environmental Assessment’s (SEA) foundations remain unclear to the point that the case for needing an instrument called ‘SEA’ could be questioned. The aim is to ask: what problems was SEA meant to solve, and what needs was it meant to address, by reflecting on the strengths and weaknesses of SEA thinking to date. I do so by organising the ...
