Since an electron’s spin magnetic moment is constant approximately the Bohr magneton , then the electron must have gained or lost angular momentum through spin—orbit coupling. Because the mechanisms of spin—orbit coupling are well understood, the magnitude of the change gives information about the nature of the atomic or molecular orbital containing the unpaired electron. The principal axes of this tensor are determined by the local fields, for example, by the local atomic arrangement around the unpaired spin in a solid or in a molecule. Choosing an appropriate coordinate system say, x,y,z allows one to “diagonalize” this tensor, thereby reducing the maximal number of its components from 9 to 3: Here Bx, By and Bz are the components of the magnetic field vector in the coordinate system x,y,z ; their magnitudes change as the field is rotated, so does the frequency of the resonance. For a large ensemble of randomly oriented spins, the EPR spectrum consists of three peaks of characteristic shape at frequencies gxxB0, gyyB0 and gzzB0: Such situations are commonly observed in powders, and the spectra are therefore called “powder-pattern spectra”. Greater complexity arises because the spin couples with nearby nuclear spins.

For a large ensemble of randomly oriented spins, the EPR spectrum consists of three peaks of characteristic shape at frequencies gxxB0, gyyB0 and gzzB0: Such situations are commonly observed in powders, and the spectra are therefore called “powder-pattern spectra”. Greater complexity arises because the spin couples with nearby nuclear spins. The magnitude of the coupling is proportional to the magnetic moment of the coupled nuclei and depends on the mechanism of the coupling.

Coupling is mediated by two processes, dipolar through space and isotropic through bond. This coupling introduces additional energy states and, in turn, multi-lined spectra. In such cases, the spacing between the EPR spectral lines indicates the degree of interaction between the unpaired electron and the perturbing nuclei. The hyperfine coupling constant of a nucleus is directly related to the spectral line spacing and, in the simplest cases, is essentially the spacing itself.

Bosna i Hercegovina From the book “Politics of Genocide” author dr. Herman During the civil wars that accompanied the dismantling of the Federal Republic of Yugoslavia in the s, the United States, Germany, NATO, and the European Union EU all sided with the national groups seeking to break away from the unified federal state, and opposed the national group that held out for the longest time to preserve it, the Serbs; this placed the Western bloc solidly behind the Croats and Slovenes, then the Bosnian Muslims, and finally the Kosovo Albanians.

Because the wars were supported and even carried out by the NATO powers, and there was significant ethnic cleansing and ethnic killings, it goes almost without saying that not only “ethnic cleansing” but also the words “massacre” and “genocide” were quickly applied to Serb operations. The remarkable inflation of claims of Serb evil and violence and playing down of NATO clients’ violence , with fabricated “concentration camps, ” “rape camps,” and similar Nazi- and Auschwitz-like analogies, caused the onetime head of the U.

Steam aupreme at King’s Cross the very last word. How to get from King’s Cross to St. Pancras by a lost diesel multiple unit. There was a significant omission in my letter in the November issue! The errant train could not pass directly from the King’s Cross goods yard down a connecting spur to the Midland. That spur took it up on to the North London line, then west to St. Pancras Junction and down a second connecting spur to the Midland. Many insights provided by Mark Hopwood.

Notes the excellent coverage of the Vitry tests.

This organism is commonly considered in the differential diagnosis of a number of gram-negative infections. It is associated with nosocomial infections, often severe and life-threatening, especially in immunocompromised hosts. It can be found in large numbers on fresh fruits and vegetables. Human colonization begins within the gastrointestinal tract, with subsequent spread to moist cutaneous sites such as the perineum and axilla.

It forms smooth fluorescent green colonies at 42oC, with a characteristic sweet grape-like odor, making it easy to recognize on solid media in the laboratory.

Background. Initially identified in , excavation at Area 15 of the Gault Site was undertaken to explore evidence of early cultures in Central ch focused on the manufacturing technologies, their relationship to Clovis, and the associated age of this assemblage.

Giant handaxes suggest that different groups of early humans coexisted in ancient Europe February 23, by Martina Demuro, Lee Arnold And Mathieu Duval, The Conversation Researchers work on the archaeological site in Spain, known as Porto Maior, where the tool deposits were found. An exceptionally high density of giant handaxes dated to , , years ago has been uncovered at an archaeological site in Galicia, northwest Spain. The findings are documented in a new article published by our international research team of archaeologists and dating specialists.

The discovery of these handaxes suggests that alternative types of stone tool technologies were simultaneously being used by different populations in this area — supporting the idea that a prehistoric “Game of Thrones” scenario existed as Neanderthals emerged in Europe. Additional evidence for this idea comes from fossil records showing that multiple human lineages lived in southwest Europe around the same time period. The archaeological site at Porto Maior preserves an ancient stone tool culture known as the Acheulean.

Minor in Global Sustainability The interdisciplinary minor in Global Sustainability trains students to understand the changes that need to be made in order for the human population to live in a sustainable relationship with the resources available on this planet. See the Interdisciplinary Studies section of this Catalogue for more information. Engineering and Computer Science in the Global Context The globalization of the marketplace for information technology services and products makes it likely that The Henry Samueli School of Engineering graduates will work in multicultural settings or be employed by companies with extensive international operations, or customer bases.

The goal of the concentration is to help students develop and integrate knowledge of the history, language, and culture of a country or geographic region outside the United States, through course work both at UCI and an international host campus, followed by a technology-related internship in the host country. All of The Henry Samueli School of Engineering majors in good standing may propose an academic plan that demonstrates the ability to complete the concentration a minimum of eight courses and other requirements for graduation in a reasonable time frame.

The Associate Dean will be available to assist qualified students with the development of a satisfactory academic plan, as needed.

The epilogues in RE3 implied that nearly every main character was going to join forces to stop Umbrella. The only real thing to come out of this was Claire and Chris reuniting in Code: Veronica and Leon becoming a government agent in RE4. The Stinger for Revelations shows that Raymond and Jessica are working for the GPC and seems to hint there will be another game expanding on their roles and what they plan to do with the T-Abyss sample but nothing has been brought up about the virus or the characters since then.

Revelations 2 not being a direct sequel only makes things worse. Especially in Press X to Not Die form. All the playable female characters, not including Ashley and a young Sherry. The clearest example is RE4, but even RE2 had more of an emphasis on fighting than the first.

Catalysts are essential for the modern society as they can resolve these critical challenges. Design and development of novel catalytic materials with improved efficiency can help us tackle the challenge. The discovery of nanoparticles with varied size, shape and composition has stretched the limits of technology in ways that scientists would never have dreamt of a century ago.

Nature makes and chemistry re-shapes; huge varieties of nanoparticles have emerged in our daily life, in every field from drugs and electronics to paints and beauty care, and they are now emerging in the field of catalysis. Nano-Catalysis is becoming a strategic field of science since it represents a new way to meet the challenges of energy and sustainability. These challenges are becoming the main concerns of the global vision of the societal challenges and world economy.

Catalysis research became one of the most powerful tools to take on these challenges. The field of nanocatalysis is undergoing an explosive development. Nanocatalysis can help design catalysts with excellent activity, greater selectivity, and high stability. Their properties can easily be tuned by tailoring the size, shape, and morphology of the particular nanomaterial. Nanocatalysis is no longer just a field of academic curiosity but an emerging field for industries to develop green and sustainable processes.

However, next-generation nano-gold catalysts with very high turnover number TON and stability are needed to take this field to the next level.

GUN CONTROL: A REALISTIC ASSESSMENT

It is a juvenile cave bear femur, broken at both ends, but showing 4 holes in line. Found in by Ivan Turk in Slovenia, at the Divje Babe site, the juvenile cave bear femur bone, known as the Divje Babe flute, was a major find of recent times. The reason for that was because it provided significant evidence that Neanderthals may have been the equal of Homo Sapiens in the evolution of humankind. It became the oldest known musical instrument, and the first known instance of a diatonic musical scale sequence.

The debate was on. Others entered the debate, and the archaeological and paleo-anthropological community was split.

Stratigraphic unit numbers are shown on the left, and the cultural horizons are highlighted in gray. Clovis ages have been reported elsewhere see text. No HF etching was applied. An initial equivalent dose De estimate was made by comparing the natural OSL signal of four aliquots to their OSL signal after a given dose. A second identical regenerative dose was applied to the same four aliquots, and the Infrared Stimulated Luminescence IRSL signal was measured as a check for feldspar contamination.

Thermal transfer tests that were carried out to assess the possibility of charge transfer from light-insensitive shallow traps to light-sensitive OSL traps showed no significant thermal transfer Final De measurements were made on 48 aliquots for each measured sample. All measurements followed the SAR protocol 21 , 22 on 0.

This fraction was targeted to isolate quartz-rich silt identified through petrography 23 that was presumed to be incorporated in the floodplain sediments through aeolian processes. The OSL signal was integrated from the first 0. Aliquots were required to pass the following criteria for further analysis: All De values incorporated an instrumental error of 1.

Dose rates were calculated, assuming secular equilibrium in the U and Th decay chains. Dose rates were corrected for water content using laboratory-based measurements and for attenuation using factors from Brennan et al.
