Landfills constitute the largest treatment and disposal reservoirs of anthropogenic waste on earth they are continuously releasing antibiotic resistance genes (ARGs) to environment for decades via leachates. Little is known about association between ARGs human bacterial pathogens as a function time. Here, we quantified 10 subtypes ARGs, integrons, (HBPs). Except encoding sulfonamides, beta-lact...

Detecting gravitationally lensed supernovae is among the biggest challenges in astronomy. It involves a combination of two very rare phenomena: catching transient signal stellar explosion distant galaxy and observing it through nearly perfectly aligned foreground that deflects light towards observer. High-cadence optical observations with Zwicky Transient Facility, an unparalleled large field v...

A better understanding of past climate change is vital to our ability predict possible future environmental dynamics. This study attempts investigate the dynamic features temporal variability peat humification, water table depth and air temperature by analyzing palaeoecological data from Valdai Uplands region (Central European Russia). The regression analysis revealed presence a periodicity abo...

The issue uses ecological footprint method to research 7 target counties of Beijing and gains the per capita ecological deficit after 12 percent areas deduction for biological diversification. We found that target region has a magnified trend of ecological deficit and then, we try to offer some proposals about how to develop the mountainous counties.

In this note we construct a simple international differentiated duopoly model that involves a divisionalization decision. It will be shown that the number of third market divisions of a parent firm with a cost advantage is relatively large. The results imply that the cost competitiveness of one country’s firm will be magnified through divisionalization decisions.

This paper presents efficient methods for implementing general non-linear magnification transformations. Techniques are provided for: combining linear and non-linear magnifications, constraining the domain of magnifications, combining multiple transformations, and smoothly interpolating between magnified and normal views. In addition piecewise linear methods are introduced which allow greater e...
