The present contribution is concerned with an exact frame-based pulsed-beams expansion of planar aperture timedependent electromagnetic fields. The propagating field is described as a discrete superposition of tilted, shifted and delayed electromagnetic pulsed-beam waveobjects over the frame spectral lattice. Explicit asymptotic expressions for the electromagnetic pulsed-beam propagators are ob...
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...
Background: Photo-damaged skin is characterized not only by wrinkles and creases but also by epidermal and dermal atrophy, rough skin texture, irregular pigmentation, talengiectasis , laxity and enlarged pores. There is growing interest in the development of noninvasive methods to treat photo-damaged skin. Intense Pulsed Light (IPL), a non-coherent, broadband, pulsed light source is effective i...
Background and purpose:Diazinon is an organophosphorus insecticide, which is classified as a relatively dangerous product by the World Health Organization. Entrance of this pollutant into water resources can have detrimental effects on human health and environment. The aim of the present study was to evaluate the performance of pulsed alternative current and the electrocoagulation-flotation (...
Weld area and weld depth/width ratio can be considered to be of the most important geometrical factors in pulsed laser welding. The effects of carbon dioxide and oxygen additions to the argon shielding gas on the weld properties in pulsed laser welding of low carbon steel is investigated. Presence of carbon dioxide and oxygen up to 10 and 15 percent respectively decreases the weld geometrical f...
Magnesium alloys are very attractive materials owing to their properties of low density, high specific strength and stiffness, good castability, and weldability. AZ31 magnesium alloys in terms of weldability has better situation than the other, so it has more applications than other magnesium alloys. In this study, TIG and pulsed TIG welding method was used to welding the AZ31 alloy and finally...
Thymus-dependent (T) lymphocytes from (2 x 13)F1 hybrid guinea pigs immunized to ovalbumin (OVA) in complete Freund's adjuvant can be stimulated to proliferate in vitro by antigen-pulsed peritoneal exudate cells (PECs) derived from either strain 2 or strain 13 donors. In this communication, we show that the population of primed F1 T lymphocytes which can be activated by antigen-pulsed strain 2 ...
objective: dendritic cells (dcs) are essential for the activation and polarization of t cells during an adaptive immune response. in this research we investigated the effect of the lymphoide dcs pulsed with heat-treated tumor lysate (htl) as a vaccine in tumor immunotherapy. materials and methods: the balb/c mice were injected subcutaneously in the right flank with wehi-164 fibrosarcoma cells ...
Fujikura has achieved an output power of 30 W from a Q-switched pulsed fiber laser with a pulse width about 100 ns for the first time in the world. Following the achievement, we commercialized a 70 W output pulsed fiber laser . In the article, we describe our activities on high-power pulsed fiber lasers, and introduce our 70 W output products. Fujikura’s advanced and original functions of pulse...
