The objective of this project was to use sucrose as a partial substitute for melamine in the synthesis of sucrose–melamine-formaldehyde (SMF) resin. The SMF was synthesized in a base condition. The wet bonding strength, shelf life, and formaldehyde emission of the SMF resin were determined. Fourier transform infrared spectroscopy (FT-IR) and mass spectroscopy (MS) were employed to analyze the c...

BACKGROUND In the literature, various in vivo studies on animals have demonstrated that a static magnetic field (SMF) might maintain microvascular tone in the cutaneous microcirculatory system by its biphasic effects on vasomotion. Here, the effects of locally applied SMF on skin blood flowmotion within the stressed or unstressed skin in the trochanter area were evaluated using wavelet analysis...

Static magnetic field (SMF) therapy, applied via a permanent magnet attached to the skin, is used by people worldwide for self-care. Despite a lack of established SMF dosage and treatment regimens, multiple studies are conducted to evaluate SMF therapy effectiveness. Our objectives in conducting this review are to:(i) summarize SMF research conducted in humans; (ii) critically evaluate reportin...

Cellular stress response proteins like Hsp70 may be affected by exposure to static magnetic fields (SMF). We examined whether exposure to a 100 mT SMF and GSH-depleting diethymaleate (DEM) would affect the levels of Hsp70 mRNA in HL-60 cells. Cells were exposed to SMF, DEM, a combination of DEM and SMF as well as 42oC. We found that only exposure to 42oC significantly affected the levels of Hsp...

We have investigated the effects of ionizing radiation-induced changes on dispersion and refractive index in photonic crystal fibre, boron co-doped photosensitive fibre and standard SMF-28 fibre up to a level of 7 MGy of 60Co γ -radiation. We have been unable to observe any changes within an experimental error of ∼1% for the dispersion value and <1.5 × 10−3 for the refractive index.

A compact, highly sensitive optical fiber displacement and curvature radius sensor is presented. The device consists of an adiabatic bi-conical fused fiber taper spliced to a single-mode fiber (SMF) segment with a flat face end. The bi-conical taper structure acts as a modal coupling device between core and cladding modes for the SMF segment. When the bi-conical taper is bent by an axial displa...

effect of static magnetic field (smf) on plants is a matter of debate. in the present study plausible useful effects of smf on wheat plant (triticum aestivum l.) via improvement of antioxidant system and iron/ferritin fortification were evaluated. the plants were cultivated in pots and in their reproductive stages were treated with or without a 30 mt smf for 4 days, each 5h. the activity of ant...
