background: the effects of extremely low frequency electromagnetic fields (elf-emf) on toxoplasma gondii have not been explained yet. the aim of this study was to assess the possible effects of elf-emf on growth, survival time and viability of toxoplasma gondii . in addition, the life span of toxoplasma infected animals was investigated. methods: sixty adult male balb/c mice were used for in vi...

background: the use of dendritic cells (dcs) as a cellular adjuvant provides a promis-ing approach in immunotherapy of cancer. it has been demonstrated that listeria mono-cytogenes activated dcs pulsed ex vivo with tumor antigens trigger a systemic th1-biased specific immune response and a single dose of this vaccine will cause a consider-able anti tumor immunity. objective: the present study w...

Deflection of two-level atoms by a pulsed standing wave with a pulse duration of a few nanoseconds is studied by using the density matrix formalism. The effect of the limited coherence time of the pulsed laser field on the momentum distribution of the deflected atoms is investigated. In particular, we determine the coherence time at which the deflection by a pulsed standing wave differs signifi...

Background and aim: Laser is one of the most recent techniques which has widespread use in the treatment of many skin diseases. This technique has been successfully used to remove unwanted hairs in hirsutism. The aim of this study was to evaluate and compare the efficacy and safety of long-pulsed 755 nm alexandrite and long-pulsed 1064 nm Nd: YAG lasers individually and in combination for perma...

In this paper, we consider the acceleration of plasma fluxes in crossed electromagnetic fields. The possible technical approach to a prospective accelerator is discussed. A simple hydrodynamic model describing dynamics ring these fields proposed. Based on model, estimations basic characteristics for accelerated flux are calculated typical experimental conditions.

Many devices, particularly power devices, are not designed to operate continuously or with CW signals. This is especially true when devices are being tested on-wafer, where the thermal resistance is greatly increased [1]. In these cases, S-parameter measurements are best performed in a pulsed test environment. The details of pulsed measurement are greatly dependent on the pulse properties being...
