چکیده
We describe design of optimized undulator with SC windings able to generate magnetic field of opposite helicities, including elliptic and a linear ones oriented as desired. For undulator period 25mm, aperture 8mm, length ~10m (single piece), K factor could be changed from zero up to 1.5 by changing the feeding current. 1. OVERVIEW Undulators are planned for installation in all SR facilities. Unique properties of Undulator Radiation (UR), make it being a powerful tool for exploration in wide sciences. Properties of UR are well known (see for example [1]-[3]). Important properties of UR are monochromaticity and polarization. One unique peculiarity of installation such undulators at linear accelerators (ERL, FEL, ILC, etc) is that aperture of undulator could be small; no necessity to make it with varying aperture, as it required in cyclic machines for injection of beam in storage ring. Total number of photons in all spectrum radiated by single particle in undulator having M periods and undulatority factor K 1 ≤ goes to be

Surface-enhanced Raman scattering of 4-aminothiophenol adsorbed on silver nanosheets deposited onto cubic boron nitride films.
A simple method was found for the fabrication of silver nanosheets (AgNS) by the catalysis of gold nanoparticles (AuNP) on an amine-terminated cubic boron nitride (cBN) surface deposited on a Si(001) substrate in the presence of reductant. The morphology of the AgNS/AuNP/NH(2)-cBN/Si(001) sample was characterized by scanning electron microscopy and X-ray diffraction. The performance of the AgNS...
متن کاملCannabinol-mediated inhibition of nuclear factor-kappaB, cAMP response element-binding protein, and interleukin-2 secretion by activated thymocytes.
Cannabinol (CBN), an immunosuppressive cannabinoid and ligand for the peripheral cannabinoid receptor CB2, inhibits the cAMP signaling cascade in forskolin-stimulated thymocytes. The objective of the present studies was to further characterize the mechanism of CBN immune modulation by investigating its effects on interleukin-2 (IL-2) secretion, cAMP response element (CRE), and kappaB DNA bindin...
متن کاملColumbianadin Inhibits Cell Proliferation by Inducing Apoptosis and Necroptosis in HCT116 Colon Cancer Cells.
Columbianadin (CBN), a natural coumarin from Angelica decursiva (Umbelliferae), is known to have various biological activities including anti-inflammatory and anti-cancer effects. In this study, the anti-proliferative mechanism of actions mediated by CBN was investigated in HCT-116 human colon cancer cells. CBN effectively suppressed the growth of colon cancer cells. Low concentration (up to 25...
متن کاملCannabinol enhancement of interleukin-2 (IL-2) expression by T cells is associated with an increase in IL-2 distal nuclear factor of activated T cell activity.
It has been demonstrated previously that cannabinol (CBN) differentially modulates interleukin-2 (IL-2) protein secretion by T cells with a corresponding change in extracellular signal-regulated kinase activity. The objective of the present studies was to further investigate the molecular mechanism by which CBN enhances IL-2 gene expression using the EL4 T cell line. We demonstrate here that st...
متن کاملQuantitative analysis of contraction band and coagulation necrosis after ischemia and reperfusion in the porcine heart.
To assess the importance of contraction band necrosis (CBN) in reperfusion, CBN, coagulation necrosis (CN), and infarct size, expressed as CBN + CN, were quantitatively analyzed in 25 porcine hearts without collateral circulation. The left anterior descending coronary artery was ligated for 20, 30, 60, and 120 min and then reperfused for 8 hr (groups 1 to 4, respectively). Five hearts were not ...
متن کاملNon-Shellable Drawings of Kn with Few Crossings
In the early 60s, Harary and Hill conjectured H(n) := 1 4b2 cbn−1 2 cbn−2 2 cbn−3 2 c to be the minimum number of crossings among all drawings of the complete graph Kn. It has recently been shown that this conjecture holds for so-called shellable drawings of Kn. For n ≥ 11 odd, we construct a non-shellable family of drawings of Kn with exactly H(n) crossings. In particular, every edge in our dr...
