By Steven Schramm
This thesis describes the quest for darkish topic on the LHC within the mono-jet plus lacking transverse momentum ultimate kingdom, utilizing the complete dataset recorded in 2012 by means of the ATLAS test. it's the first time that the variety of jets isn't explicitly constrained to 1 or , therefore expanding the sensitivity to new indications. in its place, a stability among the main lively jet and the lacking transverse momentum is needed, hence choosing mono-jet-like ultimate states. Collider searches for darkish topic have ordinarily used sign types using powerful box theories (EFTs), even if evaluating to effects from direct and oblique detection experiments, the place the adaptation in strength scale renders many such comparisons invalid. The thesis gains the 1st powerful and accomplished therapy of the validity of EFTs in collider searches, and offers a method wherein the various classifications of darkish subject experiments might be in comparison on a legitimate and reasonable basis.

Geotechnical Hazards from Large Earthquakes and Heavy Rainfalls
This booklet is a set of papers provided on the overseas Workshop on Geotechnical common risks held July 12–15, 2014, in Kitakyushu, Japan. The workshop was once the 6th within the sequence of Japan–Taiwan Joint Workshops on Geotechnical risks from huge Earthquakes and Heavy Rainfalls, held less than the auspices of the Asian Technical Committee No.
Biosilica in Evolution, Morphogenesis, and Nanobiotechnology: Case Study Lake Baikal
Lake Baikal is the oldest, inner most and such a lot voluminous lake in the world, comprising one 5th of the World’s unfrozen clean water. It hosts the top variety of endemic animals recorded in any freshwater lake. till lately it remained enigmatic why this sort of excessive variety advanced within the remoted Lake Baikal.
The Diary of Queen Maria Carolina of Naples, 1781-1785: New Evidence of Queenship at Court
This paintings bargains a brand new portrayal of Queen Maria Carolina of Naples as a girl of energy with weaknesses and targets, and analyzes the Queen's activities, from her political offerings to her alliance and betrayals. A cautious exam of the interval (1781-1785) coated through the diary indicates that the everyday life of the Queen and gives key facts of her political acumen and her own relationships.

9 % normal matter (baryonic and radiation). This provides compelling evidence for the existence of DM in large abundances throughout the universe, and points toward a larger open question to follow. 4 Weakly Interacting Massive Particles While many observations indicate the presence of DM, and the Bullet Cluster provides tantalizing hints that DM is particulate, there is as-of-yet no observation of any coupling to DM beyond that of gravity. Furthermore, the strong and electromagnetic forces have already been ruled out as possibilities.
3 Astrophysical Evidence for Dark Matter 13 Fig. 3 Rotation curves for the NGC6503 dwarf spiral galaxy (left) and NGC1560 spiral galaxy (right), which are respectively 17 and 10–12 million light years away. The circular velocity is shown as a function of the distance from the galactic centre, with the gas content (dotted lines), matter content (dashed lines), and measured values shown. The difference between data and expectation gives rise to the addition of a curve representing a halo of DM which is fit to match the data (dash-dotted lines) [16] or in rare cases it can even increase.
