Greenhouse gas emissions associated with pesticide applications against invasive species constitute an environmental cost of species invasions that has remained largely unrecognized. Here we calculate greenhouse gas emissions associated with the invasion of an agricultural pest from Asia to North America. The soybean aphid, Aphis glycines, was first discovered in North America in 2000, and has ...

Recently, the demand for safflower products has been growing from year to year, which includes an increase in acreage and popularity of oil among consumers. In this article, based on scientific research, a screw press production was considered. The method regulating pressure difference pressing by means gaps between core cylinder is given. A mathematical nomogram model proposed, gives qualitati...

In the terms of operational calculus the probability characteristics of direct and reverse residual renewal time of alternating renewal process, where renewal time depends on life-time, are found. 1. Definitions, Motivations and Formulation of the Problem 1.1 According to [1] let’s consider a system which fails after random life-time X1 and is fully renewed after the lapse of random time Y1. Th...

Despite the enormous media coverage that the issue of year 2000 (Y2K) readiness has received in recent months, the focus of that coverage has been restricted almost exclusively to technological aspects. Non-technical issues have tended to be either ignored completely or given very little attention. Most importantly, not much is known about the organisational processes of preparing to face this ...

I discuss the physics reach of a fixed-target charm experiment which can reconstruct >10 charm decays, three orders of magnitude beyond the largest extant sample. Such an experiment may run at Fermilab shortly after the Year 2000. In addition to “programmatic” charm physics such as spectroscopy, lifetimes, and tests of QCD, this “Charm2000” experiment will have significant sensitivity to new ph...

The Image Reduction and Analysis Facility is a scientific image processing package widely used throughout the astronomical community. IRAF has been developed and distributed by the National Optical Astronomy Observatory in Tucson, Arizona since the early 1980’s. Other observatories and projects have written many dozens of layered external application packages. More than ten thousand journal art...
