JNS.org - California headlines this month scream “water shortage”—but the shortage is not limited to the western United States. According to a recent report by the U.S. Environmental Protection Agency, while the demand for freshwater resources is increasing, the supply remains constant and many regions are starting to feel the pressure. The report states that water managers in 40 of 50 states expect water shortages in some portion of their states within the next 10 years.
Amid this grave prognosis, a new Israeli research project might make the Jewish state an important part of the solution. Rony Wallach, a professor in the Robert H.

Despite the use of a magician, the medical mystery on this week’s House was only a little better than average.
The final solution though was unexpected and much awaited. It’s a shame the medicine was so wrong. Cole (i.e Big Love) and Kutner (i.e. Kumar) are at a magician’s show when Flynn, the magician, performs his version of Houdini’s famous Chinese Water Torture trick. In it, the magician has his arms and legs shackled and is suspended upside down in a large glass box of water. Kutner performs standard and transesophageal echocardiograms (ultrasounds of the heart), but both are completely normal. Later, House goes to talk to Flynn himself. A short time later, we are told that Flynn has passed out, and an ultrasound “revealed bleeding around the heart” which was subsequently drained (sound like cardiac tamponade). Huntington’s Disease is a particularly nasty inherited neurological disease. Lung MRIs are rarely obtained, and is not an appropriate choice here. The previous House review. Panacea: "Death In The Pot!" Part I.
“There is death in the pot!” The book of 2 Kings records that this was proclaimed, by several prophets, in response to the poisonous stew served to them. The warning allowed Elisha to add flour to the stew, and so doing, remove the harmful effects rendered by poisonous gourds. This dire warning was reprinted boldly, in capital letters, on the front cover of chemist Fredrick Accum’s 1820 book A Treatise on Adulterations of Food, and Culinary Poisons. As those who know me have discovered, I love food. It’s no surprise, really, that I was so captivated by Accum’s graphic book cover, frontispiece, and words.
As an MA student many, many years ago, I even found myself nodding along to statements such as: “of all the frauds practiced by mercenary dealers, there is none more reprehensible, and at the same time more prevalent, than the sophistication of the various articles of food.” Food adulteration, he wrote, was an “unprincipled and nefarious practice.” Health, too, was a major concern.

(CDC via AP) NEW YORK (AP) — Health officials now think Ebola survivors can spread the disease through unprotected sex nearly twice as long as previously believed. Scientists thought the Ebola virus could remain in semen for about three months. Based on the case, officials are now telling male Ebola survivors to avoid unprotected sex indefinitely. A report released Friday detailed the case of a 44-year-old Liberian woman whose infection likely came from a 46-year-old man who had Ebola symptoms last September. The Ebola virus spreads through direct contact with an Ebola patient's blood or other bodily fluids like urine, saliva, semen and sweat. In Guinea, Dr. Online: Associated Press.

Basics X-ray absorption spectroscopy is the general term encompassing both the X-ray absorption fine structure (XAFS) and X-ray absorption near-edge structure (XANES) techniques. In both techniques, X-rays are absorbed by atoms in a sample while the energy of the radiation is varied, and each element type produces a characteristic absorption pattern. This plot of absorption against energy is the X-ray absorption spectrum of the sample. The key feature of these XAS techniques is that since every element absorbs a different wavelength of X-ray radiation, each measurement can be “tuned” to exclusively look for an element of interest, simply by adjusting the wavelength of the X-ray source.
This is where a synchrotron facility becomes essential - only synchrotron X-ray sources such as DESY can provide precisely tunable X-rays. Benefits Only synchrotron X-ray radiation can provide the intense and continuously tunable X-ray beams needed for XAS. Types of samples Examples of specific applications: X-ray absorption spectroscopy. Figure 1: Transitions that contribute to XAS edges Figure 2: Three regions of XAS data X-ray absorption spectroscopy (XAS) is a widely used technique for determining the local geometric and/or electronic structure of matter. The experiment is usually performed at synchrotron radiation sources, which provide intense and tunable X-ray beams. Samples can be in the gas-phase, solution, or condensed matter (i.e. solids).
XAS data are obtained by tuning the photon energy using a crystalline monochromator to a range where core electrons can be excited (0.1-100 keV photon energy). XAS is a type of absorption spectroscopy from a core initial state with a well defined symmetry therefore the quantum mechanical selection rules select the symmetry of the final states in the continuum which usually are mixture of multiple components. Applications[edit] History[edit] An informative account about the history of XAS is given in the paper "A History of the X-ray Absorption Fine Structure" by R.

" Details The set is focused primarily on iron oxides, but also includes metallic iron and a few iron salts with organic anions. Important: To keep this from being easily solved by linear combination methods alone, and to simulate the common situation encountered in XAFS analysis of having a sample that is "almost" like a mixture of bulk materials, every sample was collected at a random temperature between 303 and 403 K.
Standards Standards collected on the same beamline, but not necessarily at the same temperatures. DivStandards.zip Known Constituents In this set, the identity of the constituents are known, but the fraction of each that is present in the sample is not known (to you, that is).

Tunable diode laser absorption spectroscopy (TDLAS) is a technique for measuring the concentration of certain species such as methane, water vapor and many more, in a gaseous mixture using tunable diode lasers and laser absorption spectrometry. [citation needed] The advantage of TDLAS over other techniques for concentration measurement is its ability to achieve very low detection limits (of the order of ppb).
Apart from concentration, it is also possible to determine the temperature, pressure, velocity and mass flux of the gas under observation.[1][2] TDLAS is by far the most common laser based absorption technique for quantitative assessments of species in gas phase. Working[edit] A basic TDLAS setup consists of tunable diode laser light source, transmitting (i.e. beam shaping) optics, optically accessible absorbing medium, receiving optics and detector/s. The emission wavelength of the tunable diode laser, viz. Basic principles[edit] Concentration measurement[edit] where, is in kelvins and.

The present invention relates to a tunable semiconductor laser adapted for laser oscillation at an optionally variable wavelength. A GaAs-Ga1-x Alx As double heterostructure distributed feedback laser diode is known as one of semiconductor lasers for effecting single longitudinal mode oscillation developed for long-distance optical transmission. The laser diode includes an active layer formed with a grating provided by a multiplicity of parallel grooves at a given spacing.
The laser diode effects stable oscillation at a selected wavelength λ given by the following equation. λ=2nΛ/m (1) where n is the refractive index of the active layer, Λ is the spacing between the grooves of the grating, and m is the order of the Bragg diffraction. An object of the present invention is to provide a tunable semiconductor laser which is adapted for stable single longitudinal mode oscillation and with which the oscillation wavelength is variable over a wide range.

Laser absorption spectrometry (LAS) refers to techniques that use lasers to assess the concentration or amount of a species in gas phase by absorption spectrometry (AS). Optical spectroscopic techniques in general, and laser-based techniques in particular, have a great potential for detection and monitoring of constituents in gas phase.
They combine a number of important properties, e.g. a high sensitivity and a high selectivity with non-intrusive and remote sensing capabilities. Laser absorption spectrometry has become the foremost used technique for quantitative assessments of atoms and molecules in gas phase. It is also a widely used technique for a variety of other applications, e.g. within the field of optical frequency metrology or in studies of light matter interactions. The most common technique is tunable diode laser absorption spectroscopy (TDLAS) which has become commercialized and is used for a variety of applications. Direct laser absorption spectrometry[edit] Jump up ^ A. X-ray absorption spectroscopy. Absorption spectroscopy. An overview of electromagnetic radiation absorption. This example discusses the general principle using visible light as a specific example. A white beam source – emitting light of multiple wavelengths – is focused on a sample (the complementary color pairs are indicated by the yellow dotted lines).
Upon striking the sample, photons that match the energy gap of the molecules present (green light in this example) are absorbed in order to excite the molecule. Other photons transmit unaffected and, if the radiation is in the visible region (400-700nm), the sample color is the complementary color of the absorbed light. An example of applying Absorption spectroscopy is the first direct detection and chemical analysis of the atmosphere of a planet outside our solar system in 2001.
Absorption spectroscopy is employed as an analytical chemistry tool to determine the presence of a particular substance in a sample and, in many cases, to quantify the amount of the substance present.

'I oppose giving cash instead of grains in the Food Security Bill' | Cover Story. M S Swaminathan, one of the world's most acclaimed scientists and administrators, is widely credited with spearheading India's Green Revolution. Currently emeritus chairman of the Chennai-based MS Swaminathan Research Foundation and a Rajya Sabha member, Swaminathan talks to TOI-Crest about challenges facing agriculture. Excerpts: Five decades after it began has the Green Revolution (GR) completely run its course? And thrown up, as many say, far too many challenges? True, we initiated the programme for breeding new semi-dwarf wheat varieties in 1963, so this is indeed the 50th anniversary of that beginning. But the first major jump in production occurred in 1968. As far as the GR running its course is concerned, what is in distress are soil and water. So yes, the ecological foundations on which sustainable agriculture is built up are in danger today.
