Multiple sclerosis(MS) is the most famous autoimmune d.sease attacking the central nervous system. It attacks people from age 20–50 years old.and.the females' attacks d.uble than males' attacks. MS is an autoimmune d.sease affecting principally the central nervous system that cause nerve sheath d.myelination followed.by axon d.mage and.paralysis. MS symptoms includ. muscle weakness, weak reflexes, muscle spasm, d.fficult in move, miss-coord.nation and.unbalance with others. There are many factors may be responsible for MS: microbial, viral, smoking, stress, environmental toxins, contaminated.d.et, and.gout. MS is wid. spread.in the populations in North Europe and.this related.to lack of vitamin d.d.e to d.crease of sunlight exposure. MS biomarkers includ. nitric oxid., interleukin-6, nitric oxid. synthase, fetuin-A and.osteopontin. MS is not a genetic d.sease where MS occurs when human leukocyte antigen system related.genes are changed.in chromosome 6. The physiology of MS is monitored.by activation of immuneinflammatory, oxid.tive, and.nitrosative stress pathways. MS is includ.ng two main steps:(1) myelin sheath d.struction and.formation of lesions and.(2) inflammation. Four types of MS can be d.stinguished. relapsing-remitting, primary progressive, second.ry progressive and.progressive relapsing. Nine treatments have been accepted.for relapsingremitting MS type: interferon b-1a, interferon b-1b, mitoxantrone, natalizumab, glatiramer acetate, fingolimod. d.methyl fumarate, teriflunomid., and.alemtuzumab, however,the only treatment used.is mitoxantrone for progressive MS but many of MS treatments sid. effects are record.d. Complementary treatments also used.in MS treatments such as:vitamin d. Yoga, med.cinal plants, oxygen therapy, acupuncture and.reflexology.

The effect of the valence band.tail wid.h on the open circuit voltage of P3HT：PCBM bulk heterojunction solar cell is investigated.by using the AMPS-1d.computer program. An effective med.um mod.l with exponential valence and.cond.ction band.tail states is used.to simulate the photovoltaic cell. The simulation result shows that the open circuit voltage d.pend. Iinearly on the logarithm of the generation rate and.the slope d.pend. on the wid.h of the valence band.tail. The open circuit voltage d.creases with the increasing wid.h of the band.tail. The d.rk and.light id.ality factors increase with the wid.h of the valence band.tail.

A stochastic based.approach for a new site classification method.application to the Algerian seismic cod.

引用

Earthquake Engineering and.Engineering Vibration 2015年第4期14卷 663-681页

作者： mohamed Beneld.ouzi Nasser Laouami Civil Engineering Faculty University of Sciences and Technology Houari Boumediene Earthquake Engineering Applied.Research Center (CGS)

Build.ng cod.s have wid.ly consid.red.the shear wave velocity to make a reliable subsoil seismic classification, based.on the knowled.e of the mechanical properties of material d.posits d.wn to bed.ock. This approach has limitations because geophysical d.ta are often very expensive to obtain. Recently, other alternatives have been proposed.based.on measurements of background.noise and.estimation of the H/V amplification curve. However, the use of this technique need. a regulatory framework before it can become a realistic site classification proced.re. This paper proposes a new formulation for characterizing d.sign sites in accord.nce with the Algerian seismic build.ng cod. (RPA99/ver.2003), through transfer functions, by following a stochastic approach combined.to a statistical stud.. For each soil type, the d.terministic calculation of the average transfer function is performed.over a wid. sample of 1-d.soil profiles, where the average shear wave (S-W) velocity, Vs, in soil layers is simulated.using rand.m field.theory. Average transfer functions are also used.to calculate average site factors and.normalized.acceleration response spectra to highlight the amplification potential of each site type, since frequency content of the transfer function is significantly similar to that of the H/V amplification curve. Comparison is d.ne with the RPA99/ver.2003 and.Eurocod.8 (EC8) d.sign response spectra, respectively. In the absence of geophysical d.ta, the proposed.classification approach together with micro-tremor measures can be used.toward.a better soil classification.

Spiropyrimid.nes vanquish a significant situation in the field.of heterocyclic chemistry, they are broad.y utilized.as an antibacterial, an inhibitor of multid.ug opposition, or an antiplatelet and.antithrombotic d.ug. Phosphate, the principal Moroccan mineral wealth occupies a vital spot in the economic sector and.its valuation is a goal continually looked.for. Among the conceivable outcomes of valorization, its utilization in heterogeneous catalysis which thought about an exceptionally encouraging new way. In this context, the focus on the reaction of the synthesis of spiropy-rimid.ne, catalyzed.by natural phosphate (NP) and.by fluoroapatite (Fap), are used.alone or d.ped.by cobalt. These phosphate catalysts were characterized.by XRd. IR and.SEM, while the synthesized.spiropyrimid.ne was id.ntified.by IR, GC-MS and.NMR. The obtained.yield.with fluorapatite d.ped.by cobalt (Co/Fap), at room temperature in ethanol is very high and.shows a high impact performance ind.ced.by a synergistic effect compared.to that of NP alone.
