Background: Tobacco use has toxic effects on different organs. This study was carried out to assess the effect of indigenous tobacco both in smoking (bidi) and smokeless (gutkha, zarda and khaini) forms on buccal cells at chromosomal level, through assessment of different nuclear anomalies as biomarker. Methods:This study was done on people living in Durgapur and its adjacent areas, West Bengal...

about half a century ago, following the introduction of urban sprawl up concept, various studies have been conducted to describe the mechanism and the formation of this phenomenon. some of these studies aimed at finding the negative and positive impacts of such phenomenon on urban area with emphasis on how such concept may be looked open from environmental, economical and social perspectives.th...

Background: The advances in cytogenetic techniques during the last few years have permitted not only the study of large populations of wild and domestic animals, but also the detection of chromosome anomalies in embryos. Chromosomal abnormalities are the most common cause of embryonic and fetal mortality in mammals. Most reports of chromosome anomalies in parthenogenetic embryos describe numeri...

abstract bicornuate uterus is class iv and septate uterus is class vin uterine anomaly classification. bicornuate uterus is almost always treated by laparotomy and metroplasty. but the treatment of choice for septate uterus is hysteroscopic metroplasty. bicornuate- septate uterus which is described in this paper is a new class of uterine anomaly(between class iv & v). the advantages of hysteros...

Concurrent with most large El Niño events, cold sea surface temperature (SST) anomalies are observed over the western Pacific warm pool region (WPWP). Observational evidence that SST anomalies that form in the off-equatorial western Pacific during El Niño–Southern Oscillation (ENSO) cycles are forced by subsurface ocean processes equatorward of 12°N and air–sea fluxes poleward of 12°N is presen...

We present results from a new, global, high-resolution (?3-km for ocean and ?6-km atmosphere) realistic earth system simulation. This simulation allows us to examine aspects of small-scale air-sea interaction beyond what previous studies have reported. Our study focuses on recurring intermittent wind events in the Gulf Stream region. These induce local heat fluxes above Sea Surface Temperature ...

This study aims to recognize effect of Ordinary Kriging (OK) and Inverse Distance Weighted (IDW) estimation methods for separation of geochemical anomalies based on soil samples using Concentration-Area (C-A) fractal model in Irankuh area, central Iran. Variograms and anisotropic ellipsoid were generated for the Pb and Zn distribution. Thresholds values from the C-A log-log plots based on the e...

In 2009, Luca and Nicolae [[Formula: see text], Integers 9 (2009) A30] proved that the only Fibonacci numbers whose Euler totient function is another number are [Formula: text]. 2015, Faye [Pell a Pell number, Publ. Inst. Math. 101(115) (2017) 231–245] text] Here, we add to these two results prove for any fixed natural if define sequence as all then solution Diophantine equation

We analyze the global structure of the worldwide air transportation network, a critical infrastructure with an enormous impact on local, national, and international economies. We find that the worldwide air transportation network is a scale-free small-world network. In contrast to the prediction of scale-free network models, however, we find that the most connected cities are not necessarily th...
