A single-beam implementation of coherent anti-Stokes Raman scattering (CARS) allows experimentally very much simplified and flexible approaches to time-resolved vibrational spectroscopy, with the additional benefit of microscopic spatial resolution. To achieve this, a broadband femtosecond laser is combined with a pulse shaper creating tailored pulse sequences by computer control. We discuss th...
Phenotypic profiling of antibiotic response signatures in Escherichia coli using Raman spectroscopy.
Identifying the mechanism of action of new potential antibiotics is a necessary but time-consuming and costly process. Phenotypic profiling has been utilized effectively to facilitate the discovery of the mechanism of action and molecular targets of uncharacterized drugs. In this research, Raman spectroscopy was used to profile the phenotypic response of Escherichia coli to applied antibiotics....
در این پروژه ابتدا از واکنش ترکیبات بنزیل برمو استات، بروماستیل بروماید و 2-برومو.4-فتیل استوفنون باتری فنیل فسفین به نسبت مولی 1:1 به ترتیب نمک های تری فنیل فسفونیوم {c6h5ch2ococh2pph3br}، {brcoch2pph3br و {phphcoch2pph3br تهیه شدند. در ادامه واکنش نمک های فسفونیوم پالادیم استات به نسبت مولی 1:2 کمپلکس های br2pd{chpph3cooch2ph}2, br2pd{chpph3cobr}2 و br2pd{chpph3cophph}2 تهیه شدهند در پایان تم...

In a referendum conducted in the United Kingdom (UK) on June 23, 2016, $51.6\%$ of the participants voted to leave the European Union (EU). The outcome of this referendum had major policy and financial impact for both UK and EU, and was seen as a surprise because the predictions consistently indicate that the ``Remain'''' would get a majority. In this paper, we investigate whether the outcome o...
background: previous researches have shown that children with autism spectrum disorder and mental retardation have some dysfunctions in attention and inhibition functions. the present study evaluated the performance of attention and response inhibition in autism spectrum disorders, mental retardation and normal children. methods: the method of this study was ex post factor, so 15 children with...
let $r$ be a commutative ring and let $m$ be an $r$-module. in this article, we introduce the concept of the zariski socles of submodules of $m$ and investigate their properties. also we study modules with noetherian second spectrum and obtain some related results.
a multicone graph is defined to be join of a clique and a regular graph. a graph $ g $ is cospectral with graph $ h $ if their adjacency matrices have the same eigenvalues. a graph $ g $ is said to be determined by its spectrum or ds for short, if for any graph $ h $ with $ spec(g)=spec(h)$, we conclude that $ g $ is isomorphic to $ h $. in this paper, we present new classes of multicone g...
BACKGROUND Compared to the waveform or spectrum analysis of event-related potentials (ERPs), time-frequency representation (TFR) has the advantage of revealing the ERPs time and frequency domain information simultaneously. As the human brain could be modeled as a complicated nonlinear system, it is interesting from the view of psychological knowledge to study the performance of the nonlinear an...
