We have investigated whether motion of gas in a bar-like potential can account for the peculiar but systematic velocity field observed in the nuclear region of the starburst galaxy NGC 253. This unusual velocity field with gradients along both major and minor axes was revealed in a high resolution (1.8′′ × 1.0′′) H92α recombination line observation by Anantharamiah and Goss (1996). A simple log...
BACKGROUND DNA barcoding aims to provide an efficient method for species-level identifications using an array of species specific molecular tags derived from the 5' region of the mitochondrial cytochrome c oxidase I (COI) gene. The efficiency of the method hinges on the degree of sequence divergence among species and species-level identifications are relatively straightforward when the average ...

The famous El Farol Bar problem [1] is an excellent demonstration of the self-referential expectation formation. As such, it serves also as a simple model of financial markets. A number of agents must decide independently each week whether to go to their favorite bar or not. If an agent expects that the bar will be overcrowded, he will stay at home; otherwise, he will go to the bar. If all agen...

The neutrino oscillation probabilities at the long-baseline accelerator experiments are expected to be modified by matter effects. We search for evidence of such modification in data T2K and NO$\nu$A, fitting hypothesis (a) oscillations (b) vacuum oscillations. find that provide as good a fit Even extended runs with 5 years mode $(5 \nu)$ five anti-neutrino \bar{\nu})$, can {\bf not} make $3~\s...
With the steady increase of the sample size of observed microlenses towards the central regions of the Galaxy, the main source of the uncertainty in the lens mass will shift from the simple Poisson noise to the intrinsic non-uniqueness of our dynamical models of the inner Galaxy, particularly, the Galactic bar. We use a set of simple self-consistent bar models to investigate how the microlensin...
امروزه صنایع یکی از عظیم ترین مصرف کنندگان آب هستند که به تبع آن حجم بالایی از پساب تولید می کنند. صنعت نساجی یکی از آنهاست که پساب تولیدی آن دارای ویژگی هایی نظیر رنگ، bod و cod بالا و وجود مواد سمی می باشد. روش های زیادی نظیر بیولوژیکی، فیزیکی، شیمیایی، غشایی و غیره برای تصفیه ی پساب ها وجود دارد. از میان روش های مختلف، در این پژوهش از روش غشایی اولترافیلتراسیون برای تصفیه ی پساب نساجی استفاد...
We report on the 2. 5 (400 pc) resolution CO (J = 1 → 0) observations covering the whole length of the bar in the strongly barred late-type spiral galaxy NGC 7479. CO emission is detected only along a dust lane that traverses the whole length of the bar, including the nucleus. The emission is strongest in the nucleus. The distribution of emission is clumpy along the bar outside the nucleus, and...
We present an analysis of bar length measurements of 3150 local galaxies in a volume-limited sample of low-redshift (z < 0.06) disc galaxies. Barred galaxies were initially selected from the Galaxy Zoo 2 project, and the lengths and widths of the bars were manually drawn by members of the Galaxy Zoo community using a Google Maps interface. Bars were measured independently by different observers...
