Photoplethysmography (PPG) is an optical technique for detection of blood volume changes in the microvascular bed a biological tissue. Many aspects PPG signal formation are still unclear. In particular, it not known how shape registered depends on geometry tissue illumination. The aim this study to model waveform using Monte Carlo (MC) method. For this, we developed three-layer skin reflectance...

A novel near-infrared (NIR) electrochromic polyelectrolyte consisting of anthraquinone imide (AQI) pendants and a poly(1-vinylimidazole bromide) main chain was synthesized via radical polymerization. Its AQI content was varied by copolymerization with 1-vinyl-3-butylimidazole bromide to improve the processability of the polymer as well as the monomer conversion. The electrochemical and electroc...

From February 2005 to September 2007, a total of 490 crocodile sharks Pseudocarcharias kamoharai, caught as by-catch in the swordfish and tuna longline fishery that operates in the tropical western Atlantic Ocean, was studied in regard to their reproductive biology. Maximum observed total lengths (L(T)) were 1220 and 1090 mm for females and males respectively, with a high proportion of the catc...

PURPOSE To investigate the biologic effect of an 810 nm diode laser on the induction of heat shock protein 70 (Hsp70) in choroid-retinal endothelial cells in vitro. METHODS Cultured rhesus macaque choroid-retinal endothelial cells (RF/6A) were irradiated using an 810 nm diode laser (spot size, 10 mm; duration, 60 s; power, 400-1,500 mW). Cell viability was assessed by annexin V- fluorescein i...

Giant sialoliths larger than 20 mm are rare. The surgery has to be performed with the minimally invasive method in order to avoid the morbidity associated with the surgical techniques. In this report the surgical removal of a giant sialolith of 25 mm by using diode laser is described. A 57year-old female was presented with a firm mass in the anterior part of the left side of the floor of the mo...

Introduction Since the earl y 1990s, housing associations have been promoted by central government and encouraged to become mainstream providers of social-rented housing for low-income fa mil ies. An accompanying shift in the role of the local authorities was envisaged, towards their becoming enablers of a range of housing options, with less emphasis on direct public-housing provision. However,...

This study examined the relationship among personal network characteristics, gratification-utilities and the frequency of use of three interactive communication technologies (landline telephone, email and instant messaging).A conceptual framework is presented, providing a rationale for three hypotheses predicting positive relationships between personal network characteristics (size, intimacy an...
