Erosion rate study at the Allchar deposit (Macedonia) based on radioactive and stable cosmogenic nuclides (26Al, 36Cl, 3He, and 21Ne)

This paper focuses on constraining the erosion rate in the area of the Allchar Sb-As-Tl-Au deposit (Macedonia). It contains the largest known reserves of lorandite (TlAsS2), which is essential for the LORanditeEXperiment (LOREX), aimed at determining the long-term solar neutrino flux. Because the erosion history of the Allchar area is crucial for the success of LOREX, we applied terrestrial in situ cosmogenic nuclides including both radioactive (26Al and 36Cl) and stable (3He and 21Ne) nuclides in quartz, dolomite/calcite, sanidine, and diopside. The obtained results suggest that there is accordance in the values obtained by applying 26Al, 36Cl, and 21Ne for around 85% of the entire sample collection, with resulting erosion rates varying from several tens of m/Ma to ∼165 m/Ma. The samples from four locations (L-8 CD, L1b/R, L1c/R, and L-4/ADR) give erosion rates between 300 and 400 m/Ma. Although these localities reveal remarkably higher values, which may be explained by burial events that occurred in part of Allchar, the erosion rate estimates mostly in the range between 50 and 100 m/Ma. This range further enables us to estimate the vertical erosion rate values for the two main ore bodies Crven Dol and Centralni Deo. We also estimate that the lower and upper limits of average paleo-depths for the ore body Centralni Deo from 4.3 Ma to the present are 250–290 and 750–790 m, respectively, whereas the upper limit of paleo-depth for the ore body Crven Dol over the same geological age is 860 m. The estimated paleo-depth values allow estimating the relative contributions of 205Pb derived from pp-neutrino and fast cosmic-ray muons, respectively, which is an important prerequisite for the LOREX experiment

Protección Social: Infraestructura Regional de Distribución de Asistencia Alimentaria

Este artículo describe los problemas de Rusia la creación de infraestructura regional de distribución de asistencia alimentaria (FAD) para la población en necesidad. Este artículo proporciona un programa , en el ámbito del apoyo estatal - garantías estatales de ayuda alimentaria - la formación de asociaciones públicoprivadas para organizar el funcionamiento de la empresa en los complejos de infraestructura. En el cambio de la tecnología de venta - el centro de logística operativa (OLC) introducción a la cadena alimentaria que permitirá a los productores para aumentar el volumen de productos vendibles a través de redes comerciales en sintonía con los requisitos tecnológicos Abstract. This article describes the problems of Russia and countries wthe state support for domestic producers within the "green box" of the WTO; use of unsuitable land for organic farming, Abstract. This article describes the problems of Russia, ensuring the availability of needy sections of the population to a healthy diet, the state support for domestic producers within the "green box" of the WTO; use of unsuitable land for organic farming, production of ecologically clean food. On the basis of the study the authors propose a program of measures, which are classified according to spheres of influence. In the field of state support - phased expansion of state guarantees. In the area of domestic food aid to the population - the formation of public-private partnership in the creation and organization of functioning of the enterprises infrastructure complex, changing the structure of assets, primarily allocated to direct support for farmers, co-ordination of interaction between participants, members of the industrial, social, credit and financial and trade sphere, functioning settlement and payment system. In the science and technology field - development of infrastructure power industry, technological equipment of the cooking process by eliminating losses in the individual process stages. The resource base of food development - an increase in agricultural production, increasing the production capacity of the processing enterprises, optimize the flow of food in the technological cycle. The changing architecture of the sales process - the introduction of the food production chain and logistics centers (PLC), which will allow manufacturers, bypassing the retail chains, to increase the volume of conditioned food corresponding to the technological requirement

Synchronous motion of two vertically excited planar elastic pendula

The dynamics of two planar elastic pendula mounted on the horizontally excited platform have been studied. We give evidence that the pendula can exhibit synchronous oscillatory and rotation motion and show that stable in-phase and anti-phase synchronous states always co-exist. The complete bifurcational scenario leading from synchronous to asynchronous motion is shown. We argue that our results are robust as they exist in the wide range of the system parameters.Comment: Submitte

Radiation hardness qualification of PbWO4 scintillation crystals for the CMS Electromagnetic Calorimeter

This is the Pre-print version of the Article. The official published version can be accessed from the link below - Copyright @ 2010 IOPEnsuring the radiation hardness of PbWO4 crystals was one of the main priorities during the construction of the electromagnetic calorimeter of the CMS experiment at CERN. The production on an industrial scale of radiation hard crystals and their certification over a period of several years represented a difficult challenge both for CMS and for the crystal suppliers. The present article reviews the related scientific and technological problems encountered
