Landfill leachates are potential threats for environmental degradation. This study was conducted to determine the leachate quality, to identify the dominant pollutants and to evaluate the leachate pollution potential of an active and closed dumping ground of an uncontrolled municipal solid waste landfill site in Kolkata, India using leachate pollution index. The results of the physico-chemical ...

Rheumatoid arthritis (RA)-related pulmonary disorders specifically airway abnormalities and interstitial pneumonia (IP) are important extra-articular manifestations. The forced oscillation technique (FOT) is a useful method to assess respiratory impedance, respiratory resistance (Rrs) and reactance (Xrs), at different oscillatory frequencies during tidal breathing. The aim of this study was to ...

We have investigated the mechanism of S-phase arrest elicited by the carcinogen benzo(a)pyrene dihydrodiol epoxide (BPDE) in p53-deficient cells. Inhibition of DNA synthesis after BPDE treatment was rapid and dose dependent (approximately 50% inhibition after 2 h with 50 nM BPDE). Cells treated with low doses (50-100 nM) of BPDE resumed DNA synthesis after a delay of approximately 4-8 h, wherea...

We propose a “debt view” to explain the dominant international role of dollar. Within simple capital-structure model with debt-currency choice, we show that “dominant currency” is one (1) depreciates in global downturns over horizons typical debt maturity and (2) has steepest nominal yield curve. Empirically, dollar fits this description better than other major currencies. The view can dollar-d...

The present paper aims to study the effect of skill complexity during different delays on bidirectional transfer on bidirectional transfer of tracking task in different stages (pretest, acquisition phase, immediate transfer, one-day delayed transfer, two-day delayed transfer, and seven-day delayed transfer). Three variables including handedness, time lagges, and skill complexity were studied. T...
