Methanolic and aqueous extracts of Dendrophthoe falcata Linn. leaves which belongs to the Loranthaceae family, were evaluated through DPPH (1, 1-diphenyl -2-picryl-hydrazyl), antilipid peroxidation and nitric oxide scavenging methods to assess the antioxidant activity. Methanolic and aqueous extracts of Dendrophthoe falcata leaves were also evaluated for their anti-inflammatory activity by carr...

Background and Aim: The conventional procedure for removal of porcelain laminate veneers (PLVs) is time-consuming and inconvenient. The purpose of this study was to evaluate the efficacy of Er:YAG laser for debonding of PLVs. Materials and Methods: Forty-eight intact extracted human maxillary anterior teeth received discoid PLVs (24 feldspathic and 24 e-max ceramic). The PLVs had 0.7 mm thickn...

The recent development by Casio of the hand-held ClassPad 300 device raises a number of important questions for the design of mathematical learning experiences for students. This paper provides a brief description of the ClassPad 300 and its mathematical capabilities, followed by a description of the idea of an eActivity, well provided for in the operating system of the device. As their name su...

Insiders trade not only because they have private information about their companies but also because of other exogenous reasons. Therefore, it is important to control for exogenous trading needs in empirical studies regarding insider trading. Lee (1997) shows that insider trading is not closely related to the long-term performance of primary seasoned equity offering firms. This paper examines w...

In this study, a simple and green protocol to obtain hydrochar high-added value products, mainly 5-hydroxymethylfurfural (5-HMF), furfural (FU), levulinic acid (LA) alkyl levulinates, by using the hydrothermal carbonization (HTC) of orange peel waste (OPW) is presented. Process variables, such as reaction temperature (180–300 °C), time (60–300 min), biomass:water ratio initial pH were investiga...

The recovery of bioactive products with green processes is a critical topic for the research and industry fields. In this work, application solid–liquid (SLE), microwave-assisted extraction (MAE) aq. ethanol 90% v/v supercritical fluid (SFE) CO2 biocomponents from Scenedesmus obliquus studied. effects examined were temperature (30–60 °C), time (6–24 h), solvent-to-biomass ratio (20–90 mLsolv/gb...

background and objective: microbial protein production can resolve one of the major world challenges, i.e. lack of protein sources. candida tropicalis growth was investigated to specify a medium to reach the highest cell proliferation and protein production. material and methods: fractional factorial design and the index of signal to noise ratio were applied for optimization of microbial protei...

We have developed a chip-based cell culture system for the three-dimensional cultivation of cells. The chip is typically manufactured from non-biodegradable polymers, e.g., polycarbonate or polymethyl methacrylate by micro injection molding, micro hot embossing or micro thermo-forming. But, it can also be manufactured from bio-degradable polymers. Its overall dimensions are 0.7 1 x 20 x 20 x 0....

Fe films in a coverage range of 0.4<u<4.7 ML were deposited on a Mo~110! substrate in the 300<T <700 K temperature range. It is found that growth around 300 K is mediated by the step-flow growth mechanism, in contrast with previous studies of the Fe/Mo~110! and Fe/W~110! systems, where growth at 300 K was mediated by two-dimensional island nucleation and coalescence. This difference is attribut...
