The Simplicity of Steam Sterilization

Autoclave Validation

Data Loggers for Sterilization ApplicationsWarner, NH, USA — Despite the many sterilization methods available today, steam sterilization continues to rise as a top choice because of its simple yet effective decontamination method.

Through the use of an autoclave, this process involves four parameters: steam, pressure, temperature and time.

A successful cycle directly exposes the contaminated items to steam at the required temperature and pressed for the specified time.

Steam sterilization is typically carried by using a high-pressure chamber, known as an autoclave. Once the chamber is sealed, steam is pumped into the top and sides of the chamber, forcing the air out. Continue reading

Human-made aerosols identified as driver in shifting global rainfall patterns

The results of the climate system-model simulations conducted by researchers Brian Soden and Eui-Seok Chung from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science revealed that changes in clouds, as a result of their interaction with these man-made aerosols in the atmosphere, are driving large-scale shifts in rainfall and temperature on Earth.

Thermal Imaging Speeds Up Repair of Printed Circuit Boards

FLIR’s New ETS320 Thermal Infrared Imager Belgium. —  FLIR Systems has published an application note that describes how their ETS320 thermal infrared imaging camera is being used by ISOMEDIA GmbH (Stuttgart, Germany) to investigate and speed-up the repair of assembled printed circuit boards (PBA).

Earlier this year the company invested in a FLIR ETS320 non-contact thermal measurement system.

The new portable system, which pairs a high sensitivity infrared camera with an integrated stand, has enabled ISOMEDIA to undertake hands-free thermal analysis of printed circuit boards and other small electronics. Continue reading

Global Warming 101

Everything you wanted to know about our changing climate but were too afraid to ask

March 11, 2016 Amanda MacMillan

Screen ShotStop TrumpOnline. —  This is a Q & A structured web page on the NRDC website that presents a straightforward description of the issue of Global Warming.

It starts simply like this:

Q: What is global warming?

A: Here’s a simple definition of global warming. (And yes, it’s really happening.) Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history.

And experts see the trend is accelerating: All but one of the 16 hottest years in NASA’s 134-year record have occurred since 2000.

Climate change to deplete some US water basins used for irrigation

New study by MIT climate scientists experts

Solomon Hsiang et al. Estimating economic damage from climate change in the United States. Science, 2017 DOI: 10.1126/science.aal4369Online — Study finds that certain hot spots in the country will experience severe reductions in crop yields by 2050, due to climate change’s impact on irrigation.

The most adversely affected region, according to the researchers, will be the Southwest. Already a water-stressed part of the country, this region is projected to experience reduced precipitation by mid-century.

Less rainfall to the area will mean reduced runoff into water basins that feed irrigated fields. Continue reading

New Superconducting Undulators Key to Next-Gen XFELs

By CSA Editor

Online — Researchers at the US Department of Energy’s Lawrence Berkeley National Laboratory (BNL) and Argonne National Laboratory (CSA CSM) have collaborated to design, build and test two superconducting undulator (SCU) devices that could make X-ray lasers more powerful, versatile, compact and durable.

In tests, the prototype SCUs successfully produced stronger magnetic fields than conventional permanent magnetic undulators of the same size. The fields, in turn, can produce higher-energy laser light to open up a broader range of experiments, according to the team.

Researchers consider superconducting undulators a key enabling technology for the next generation of large-scale X-ray lasers in the works around the globe, projects that will allow scientists to probe the properties of matter at ever smaller and faster scales. Continue reading

Today’s Extreme Heat May Become Norm Within a Decade

When 2015 blew the record for hottest year out of the water, it made headlines around the world. But a heat record that was so remarkable only two years ago will be just another year by 2040 at the latest, and possibly as early as 2020, regardless of whether the greenhouse gas emissions warming the planet are curtailed.

That is the conclusion of a new study that uses climate models to project when today’s climate extremes will become commonplace — or the “new normal” as they are often called in both media reports and scientific analyses. Continue reading

PAGES2k Consortium Geo Temperature Histories

Global database for temperature reconstructions of the Common Era

PAGES2k-networkOnline. —  The PAGES2k Phase 2 collection is a community-sourced compilation of temperature-sensitive proxy records associated with the PAGES2k initiative.

The (soon to be published) database gathers 692 records from 648 locations, including all continental regions and major ocean basins.

The records are from trees, ice, sediment, corals, speleothems, documentary evidence, and other archives. They range in length from 50 to 2000 years, with a median of 547 years, while temporal resolution ranges from biweekly to centennial. Continue reading

Climate change damages US economy, increases inequality

Severe costs ahead especially in south and lower midwest

Solomon Hsiang et al. Estimating economic damage from climate change in the United States. Science, 2017 DOI: 10.1126/science.aal4369Online. — Unmitigated climate change will make the United States poorer and more unequal, according to a new study.

The poorest third of counties could sustain economic damages costing as much as 20% of their income if warming proceeds unabated.

Overall, the study — led by Solomon Hsiang of the University of California, Berkeley, Robert Kopp of Rutgers University-New Brunswick, Amir Jina of the University of Chicago, and James Rising, also of UC Berkeley — projects losses, economic restructuring and widening inequality.
