Iraq is located in the extreme northeastern part of the Arabian Plate, which is in collision with the Iranian (Eurasian) Plate. The collision, which is still ongoing has created tens of folds some of ...which exhibit different types of faults. The exerted compressional forces are believed to be decreasing southwestwards as being far from the collision area (Suture Zone). Accordingly, all the existing tectonic and geological maps compiled by different authors and all the existing published articles, reports and books have considered two main tectonic domains in Iraq. The Stable Shelf and Unstable Shelf or Inner Platform and Outer Platform. The contact between these two main divisions follows almost the Euphrates River; towards the west of the river is the tectonically Stable area and towards the east and north is the tectonically Unstable area, which means the presence of different structural forms. In the current study, we have recognized tens of different Neotectonic evidence in the Stable part indicating that the area is tectonically not stable. Among those indications are abandoned valleys, development of sinkholes along certain lineaments, bending of valleys in right angles, and development of nick-points in valleys along certain lineaments.

The origin of the lightest scalar mesons is studied in the framework of the instanton liquid model of the QCD vacuum. The impact of phonon-like vacuum excitations on the
σ
-meson features is ...qualitatively analyzed. In particular, it is noticed that the changes produced in the scalar sector may unexpectedly become quite considerable in spite of insignificant values of corrections to the dynamical quark masses and then the medley of
σ
-meson and those excitations may reveal itself as broad resonance states of different masses.

Iraq is located in the northeastern part of the Arabian Plate, which is colliding with the Iranian Plate. The collision between the two plates has developed the tectonic framework of the Iraqi ...territory. Accordingly, two major tectonic divisions are developed: Inner Platform (Stable Shelf) and Outer Platform (Unstable Shelf). The former (Inner platform) is almost stable forming flat terrain with tens of the Neotectonic indications. Whereas, the latter (Outer Platform) is deformed mountainous area with anticlines and major thrust faults. The contact between these two major tectonic divisions run almost along the Euphrates River. In Western Iraq, an outstanding tectonic feature exists, the Anah anticline running almost E–W direction. On both northern and southern sides of the anticline, flat and undulatory plains occur without any tectonic features. Anah anticline shows clear geomorphological and structural forms, which indicate its lateral growth, especially eastwards. Among those indications are water gaps, wind gaps, curved valleys, inclined valleys, and wale-back shape. Although the Euphrates River dissects the anticline in its eastern part; however, most probably the river runs along the crossing area between two main tectonic zones indicating that the anticline is still growing laterally eastwards, and even effecting on the contact of the Inner Platform and Outer Planform.

Straw drift chambers are used for the Large Area Tracking (LAT) of the Common Muon and Proton Apparatus for Structure and Spectroscopy (COMPASS) at CERN. An active area of 130
m
2 in total is covered ...by 12
440 straw tubes, which are arranged in 15 double layers. The design has been optimized with respect to spatial resolution, rate capability, low material budget and compactness of the detectors. Mechanical and electrical design considerations of the chambers are discussed as well as new production techniques. The mechanical precision of the chambers has been determined using a CCD X-ray scanning apparatus. Results about the performance during data taking in COMPASS are described.
We present a new measurement of the longitudinal spin asymmetry A1d and the spin-dependent structure function g1d of the deuteron in the range 1<Q2<100 GeV2 and 0.004<x<0.7. The data were obtained by ...the COMPASS experiment at CERN using a 160 GeV polarised muon beam and a large polarised 6LiD target. The results are in agreement with those from previous experiments and improve considerably the statistical accuracy in the region 0.004<x<0.03.
This monograph is the English version of the book "Quantum systems with hidden symmetry. Interbasis expansions" published in 2006 by the publishing house FIZMATLIT (Moscow) in Russian. When compiling ...this version of the book, typos and inaccuracies noted since the release of the Russian edition have been corrected.
This proceedings volume provides a comprehensive overview of the selected reports given at the International Workshops on Very High Multiplicity Physics from 2000 through 2007.
