the seeds of lepidium sativum (garden cress) were selected as a new source of hydrocolloid and some of its fundamental physico-chemical properties such as intrinsic viscosity and functional group were determined. ftir analysis showed that this polymer was composed of carbohydrate with functional carboxyl and hydroxyl groups. intrinsic viscosity was determined to be 1.33 ml/mg in water. the hydr...

self-determination theory (sdt) states that satisfaction of basic psychological needs, including the need for autonomy, competence and relatedness will lead to intrinsic motivation. this study examines the relationship between basic psychological needs and intrinsic motivation of iranian female students in mathematics. for this purpose, 382 students of five school responded to the scale of intr...

Experimental observations of driven and intrinsic rotation in tokamak plasmas are reviewed. For momentum sources, there is direct drive from neutral beam injection, lower hybrid and ion cyclotron range of frequencies waves (including mode conversion flow drive), as well as indirect j B × forces from fast ion and electron orbit shifts, and toroidal magnetic field ripple loss. Counteracting rotat...

Since the discovery of the accelerated expansion of the universe, it was necessary to introduce a new component of matter distribution called dark energy. The standard cosmological model considers isotropy of the pressure and assumes an equation of state p = ωρ, relating the pressure p and the energy density ρ. The interval of the parameter ω defines the kind of matter of the universe, related ...

Developing successful knowledge management (KM) processes is extremely difficult. In general, a large number of all KM projects end unsuccessfully. The aim of this paper is to summarize and study the attempts to take advantage of Lessons Learned in the Swedish Armed Forces (SwAF), focusing on international missions. Relevant reports, articles and literature have been studied. With the purpose o...

In 1923, renowned architect Le Corbusier authored what is largely considered to be the bestselling architecture book of all time, Vers Une Architecture ("Towards a New Architecture"). Within the pages of his impassioned manifesto, he claimed that “A house is a machine for living.” Architecture, he claimed, is able to improve people’s lives. For Le Corbusier, Victorian cities were chaotic and da...

We build a theoretical platform for predicting the behavior of tethered-bead single-molecule experiments, accounting for bead translational and rotational fluctuations, the specific type of experimental setup, and the detailed application of tension to the tether molecule. Within this framework, the external force applied to the bead is distinguished from the instantaneous force transduced to t...

Assembly pathways of virus-like particles formed from a virus coat protein cage encapsulating a metal nanoparticle were studied by intrinsic fluorescence quenching. Depending on buffer conditions, the in vitro formation of a virus-like particle can take place through cooperative or non-cooperative adsorption of protein subunits on the nanoparticle template. Simple equilibrium models provided es...
