Density is a critical typology in determining sustainable urban built-form patterns. Built-formrefers to the assemblage and arrangement of the building masses in a city reflecting the spatial layout of spaces.The relationship between density and urban character is also based on at certain densities (thresholds). In a widersense, sustainable cities are a matter of density. Recent debates about t...

Lectin-like oxidized low-density lipoprotein (LOX-1), the primary receptor for oxidized low-density lipoprotein (ox-LDL) in endothelial cells, is up-regulated in atherosclerotic lesions. Statins are the principal therapeutic agents for cardiovascular diseases and are known to down-regulate LOX-1 expression. Whether the effect on the LOX-1 receptor is related to statin-mediated cholesterol-lower...

A low cost LED based spectrometer is described. This LED based spectrometer could be operated as a standalone instrument or under PC control via serial link. A total of seven wavelength selections are available by the plug-and-measure LED light module. With the seven wavelength selections, the LED based spectrometer could provide qualitative visible absorption spectra that predict the absorptio...

The goal of this study was to investigate whether glucocorticoids (GCs) take part in cognition impairment after exposure to chronic low-power-density microwave (MW) fields. We exposed Wistar rats to a 2.45-GHz pulsed MW field at an average power density of 1 mW/cm(2) for 3 h daily, for up to 30 days. Our results show that MW-exposed rats had significant deficits in spatial learning and memory p...

Acoustic cavitation has been shown to load drugs, proteins and DNA into viable cells as a complex function of acoustic and nonacoustic parameters. To better understand and quantify this functionality, DU145 prostate cancer cell suspensions at different cell concentrations (2.5 x 10(5) to 4.0 x 10(7) cells/mL) were exposed to 500 kHz ultrasound (US) over a range of acoustic energy exposures (2 t...

Colour harmony plays an important role in fine arts, architecture and design. But it can be also important to describe the quality of light sources: the distortion of perceived colour harmony of a set of colour samples under a light source can be a relevant factor by ranking the perceived colour quality of different light sources. In an earlier experimental study[1], we came to the conclusion t...

Objective: Literature has confirmed the pathogenic role of cadmium (Cd) and its exposure in the induction of dyslipidemia implicated in the development and increasing incidence of cardiovascular diseases. The current study explored whether polyphenolics isolated from virgin coconut oil (VCO) prevent Cd-induced dyslipidemia and investigate the underlying mechanism of action, in rats. Materials a...

The study was conducted to determine the effect of dietary energy on milk yield and its composition under the influence of bovine somatotropic (bST) hormone in Nili Ravi buffaloes. Multiparous buffaloes (n=12) at mid lactation and similar level of production were selected and randomly divided into three groups (A, B and C) with four animals in each group in a completely randomized design. All t...

Background: The human body contains of different tissues and cavities with different physical and radiological properties. Most important among these are tissues and cavities that are radiologically different from water, including lungs, sinuses and bones. Gel dosimetry provides a unique feature to display dose distributions occurring in clinical radiation therapy in three dimensions. Materials...
