objective: ferula szowitsiana has been widely used for medicinal purposes around the world. the anti-oxidant effect of f.szowitsiana had been proved. the current study aims to determine the protective effects of galbanic acid, a sesquiterpene coumarin from f. szowitsiana, against hydrogen peroxide (h2o2) - induced oxidative dna damage in human lymphocytes. materials and methods: human lymphocyt...

Collision detection between moving objects is an open question which raises major problems concerning its algorithmic complexity. In this paper we present a polygon collision detection algorithm which uses polygon decomposition through triangle coverings and polygon influence areas (implemented by signs of barycentric coordinates). By using influence areas and the temporal and spatial coherence...

Nowadays, each newly produced car must conform to the appropriate safety standards and norms. The most direct way to observe how a car behaves during a collision and to assess its crashworthiness is to perform a crash test. This paper deals with the wavelet-based performance analysis of the safety barrier for use in a full-scale test. The test involves a vehicle, a Ford Fiesta, which strikes th...

A hybrid TDMA/CDMA MAC protocol for WSN is proposed that combines the strengths of TDMA and CDMA while offsetting their weaknesses. The proposed scheme allows the network to operate in a collision-free manner, and takes advantage of broadband property provided by CDMA. The main features of this hybrid protocol are high throughput and low latency. Performance of this new protocol is compared wit...

Materials designed for nuclear waste disposal include a range of ceramics, glass ceramics and glass waste forms. Those with crystalline phases have provided the momentum for studies of minerals as a means to understand aspects of waste-form crystal chemistry, behaviour in aqueous systems and radiation damage over geological periods of time. Although the utility of natural analogue studies varie...

Abstract. Cancer is a major health problem all over the world. Photo thermal therapy (PTT) is a non-invasive method in cancer treatment. In PTT, the laser light usually in near-infra red region is absorbed and converted to heat in the cancerous tissue. The temperature above 40 ° C in PTT can induce some effects including irreversible damage to proteins, changes in enzyme struc...
