The application of raw materials derived from renewable feedstock has given rise to growing interest recently, as it can be exploited for the production of bio-based materials from vegetable oils. Their availability, biodegradability and low prices have been taken into account. In this work, vegetable oil-based polyols as a prospective replacement for petroleum polyols were investigated. A two-...

A new radiometric term named as usable solar radiation (USR) is defined to represent the spectrally integrated solar irradiance in the spectral window of 400–560 nm. Through numerical simulations of optically deep waters covering a wide range of optical properties, it is found that the diffuse attenuation coefficient of downwelling USR, Kd(USR), is nearly a constant vertically for almost all oc...

Androgen receptor (AR) mediated signalling is necessary for normal development of the prostate gland and also drives prostate cancer (PCa) cell growth and survival, with many studies showing a correlation between increased receptor levels and therapy resistance with progression to fatal castrate recurrent PCa (CRPC). Although it has been held for some time that the transcription factor Sp1 is t...

Vacuum insulated panels (VIP) is an emerging technology that may constitute an alternative to rigid polyurethane (RPU) foam as insulation in refrigerators and freezers. The "skin effect" caused by the aluminum layer in the envelope complicates the evaluation of the global thermal resistance. This article present a new method of VIP characterization. Values of the global thermal resistance obtai...

The introduction of social media in the restaurant sector has changed manner which customers communicate with businesses. Social marketing activities (SMMAs), such as customization, entertainment, trendiness, and interaction may have a substantial impact on followers’ perceived value consumer behavioral intentions. Therefore, this research aims to investigate SMMAs purchase intentions (PUR), wi...

According to the French Structuralist Gerard Genette, the term “point of view” is not an all-comprehensive one for the discussion of narration because, in his view, there is often a difference between the person who tells about an event and the person who sees it. He has, thus, proposed the term “focalization” to make a distinction between the two components of narration. Later critics also pro...

Detailed knowledge about polymer flows through the anthroposphere and into environment is information essential to better management of plastics. Currently, only limited specific available. This work aimed model those for five polymers: polyurethane (PUR), acrylonitrile butadiene styrene (ABS), polyamide (PA), polycarbonate (PC) polymethyl methacrylate (PMMA). Probabilistic material flow analys...
