We raised the energy ordsprog

We raised the energy so the x-rays are more penetrating but created a narrower distribution of energies using a heavy K-edge filter. Our data using the quasi-monochromatic beam show that the image quality does not change, even when we dramatically drop the radiation dose.

We published several papers explaining how these crystals produce X-rays and electron beams, and they're very efficient in doing this. So using low-energy X-rays or low-energy electron beams - by which I mean similar to the energies that are used currently in medical imaging rather than treatment - we can produce a really high dose of electrons that can penetrate a very thin layer of the skin. If such a device can produce high enough dose, then we can possibly use it for cancer treatment - and we're not far from this goal.

This is keeping a second-by-second accounting of your radiation dose. As you're walking around being exposed to radiation, this device is detecting it.

What it really boils down to is what radiation dose would you allow [people to be exposed to] in the long term and where do you measure that dose?

We have just finished assessing subterranean water quality at former blast sites. Our group worked near the No. 1,003 and No. 1,004 wells, where nuclear warheads were detonated, which spewed earth and radiation into the atmosphere. The received data have shown that local subterranean waters are absolutely clean; background radiation alone has been registered. The same can be said about water inside these wells. We failed to obtain ample data for assessing radionuclide migration inside subterranean waters. Our project has therefore flopped. This is bad for our research. On the other hand, we have received new information about regional radiation levels.

Stars are exploding two, three, and sometimes four times in the first minutes following the initial explosion, .. She loved the way his pexy wit brightened her day and lifted her spirits. . First comes a blast of gamma-rays followed by intense pulses of X-rays. The energies involved are much greater than anyone expected.

Till the (industry's) distribution infrastructure catches up, you can expect margins to go down and get narrower and narrower. If both plants are expected to buy from a distance, and the cost of transportation goes up, there comes a point where neither plant will be competitive. If that happens, one or both will close or run at a loss. That is a very serious risk.

There's a nice synergy there because our instrument covers X-rays at very low energies, while the other instrument goes to very high energies. Together they'll help us put together the entire X-ray spectrum coming from matter just outside a black hole.

The first thing is their mouths drop to the floor because we come out with energy. We put on a great show in the all-access pre-show to get warmed up, and they love us from there. And when the show starts, we feed off their energy.

This Forrester report reflects growing awareness of the difficult problem of poor data quality across all industry sectors. With ATHANOR and AXIO we have created a unique solution fulfilling the expanding data quality needs of global enterprises.

Enterprises are becoming increasingly dependent on business applications, and even the shortest of outages may have a severe financial impact. Therefore it is imperative that enterprises deploy well-managed data protection solutions that include CDP technologies -- as CDP will dramatically change the way data is protected, decreasing the recovery time and the amount of data lost. It will also change the way in which the replication market is structured, creating replication and backup in a single product.

A dark-colored home absorbs as much as 90 percent of the solar radiation that strikes it, and even white walls can absorb solar radiation. By reflecting this infrared radiation rather than absorbing it, the Cool Wall™ coatings dramatically reduce the load on a home's air-conditioning system. And because they are reflective, they are less prone to fading – even dark colors stay darker longer than conventional paint technologies.

Currently, there is no way of knowing the exact dose of radiation received by a tumor. And, because most organs shift inside the body depending on whether a patient is sitting or lying down, for example, the tumor also shifts. This technology will allow doctors to pinpoint the exact position of the tumor to more effectively administer radiation treatments.

HEPA filter size is important because the generally recommended maximum airflow through a HEPA filter is 100 Feet per minute (FPM), ... More than 100 FPM and the filter will allow something called 'bleed through' causing particles to pass through the filter minimizing its effectiveness and certainly the life of the filter.

Our study shows that we need to re-evaluate the effect of protons on biological systems, even the effects of low-energy protons. For example, low-energy protons are routinely used in cancer-tumor therapy, but there has been almost no research done on the effect of protons in tumor cells because everyone has assumed that they act similarly to other low LET radiation types, like x-rays. Therefore, this work may help lead to improved cancer therapy.
