We apply a recently proposed mechanism – in which an SU(3) symmetry predicts the weak mixing angle – to construct realistic theories with composite quarks and leptons at a TeV. Although the models are strongly coupled, they are reliably analyzed using complementarity and ’t Hooft’s anomaly matching. In the simplest models the right-handed fermions are composite, while the left-handed are elemen...
[1] It is well known that anomalies of the Indian Summer Monsoon Rainfall (ISMR) are linked to El Niño and Southern Oscillation (ENSO). We show that large anomalies of the ISMR are also linked to the Equatorial Indian Ocean Oscillation (EQUINOO) between states with enhancement/suppression of atmospheric convection over the western part of the equatorial Indian Ocean with suppression/enhancement...
In order to gain insight into the structure of quantum field theory, one often couples relevant composite operators to external fields such that functional differentiation w.r.t. these fields yields Green functions of the respective operator. A particular variant of this method consists in replacing the coupling constant by a local coupling field. The corresponding composite operator is the loc...
The study area is located in the south of Qushadagh mountain range, in the north of Asbkhan village, Heris township. In terms of structural geology of Iran, this area is located in the main zone of Central Iran and Alborz-Azerbaijan sub-zone. The geological units of the region are including Eocene igneous and pyroclastic rocks with combination of andesitic, trachyandesitic, basaltic, tuffic and...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
Abstract The total content of rare earth elements (REEs) and the their oxalate-soluble fraction were studied in four soil profiles (Gleyic Umbrisols, Albic Gleyic Folic Retisols (Raptic), Dystric Retisol) Central Forest Nature Reserve. REE was normalized to a local standard (the Russian Platform clay), cerium europium anomalies quantified [8]. In addition initial redistribution REEs during form...
A systematic regional geochemical stream sediment survey for base metals copper, lead, and zinc over an area of 200 sq.km was carried out around Wapsa in Solukhumbu District. samples were collected from active streams analyzed them using atomic absorption spectrometry (AAS) method. All chemical analysis data interpreted with geostatistical inverse distance weighing (IDW) multivariate interpolat...
Multicomponent contaminant transport models in groundwater are typically based on assumptions of local geochemical equilibrium on the grid scale. In heterogenous systems there may be significant coupling between transport processes and geochemical equilibrium at smaller than grid block scale. When these processes are upscaled to grid scale, geochemical evolution may take on a kinetic character....
The principal objective of the current study was to elucidate the potential influence of acid mine drainage (AMD) pond on neighboring farmer's wells in the Podwiśniówka area (south-central Poland), using North American Shale Composite (NASC)-normalized rare earth element (REE) concentration profiles. The well waters generally displayed a distinctly positive Eu anomaly similar to that of parent ...
