Quantitative easing and labour market restructuring underline the ‘regressive recovery’

A combination of loose monetary policy and sustained wage deflation underpinned the Conservative’s economic recovery in the last parliament. These processes have consolidated rather than overcome weaknesses at the heart of Britain’s growth model, write Scott Lavery and Jeremy Green

Airborne Measurements of High Pollutant Concentration Events in the Free Troposphere over the West Coast of South Korea between 1997 and 2011

Aircrafts enable the direct measurement of chemical components in the free troposphere (FT). This study employed airborne measurements to examine the occurrences of high concentrations of SO2 and NOx in the FT over the coastal region west of the Seoul metropolitan area, South Korea. The data from a long-term (1997-2011) airborne measurement campaign were used to determine the meteorological conditions favorable for carrying these pollutants into the Seoul area. The back trajectory analyses of 21 instances of high FT pollutant concentration events showed ascending patterns from the major pollutant sources, mainly the industrial complexes in eastern China, in 9 instances and passing patterns in 12 instances. In the ascending instances, developing low-pressure systems over the source regions provide favorable conditions to uplift air pollutants from the surface into the FT. In the passing instances, an anomalous low-pressure system near the surface prevented airflows from descending into the boundary layer and upper-level anticyclonic systems helped to keep the ascending airflows in the FT. This study proposes the basic mechanisms for predicting air quality in the Seoul area, considering that air pollutants in the FT often entrain into the boundary layer to increase local concentrationsopen0

Improved rate capability of LiCoO2 cathode material via particle size-control for Li-ion Batteries

Department of Energy Engineering(Battery Science and Technology)For those several decades, alternative energy production and energy storage system has been actively studied due to dramatic growing of worldwide energy demands and strengthened enviromnetal regulations. Lithium-ion batteries (LIBs) have been spotlighted as a next generation energy storage system. Because lithium is the most electropositive and lightest metal, thus it has a higher volumetric and gravimetric energy density than others regardless of cell types. Layered metal oxides have been used for Li-ion battery cathodes as most popular source since the first commercial battery launched by Sony in 1991. LiCoO2 is the most popular cathode material having layered structure. It is practically and widely used in the secondary battery fields for portable devices, due to its advantages. It is easy to manufacture LiCoO2 compared to other cathode materials, leading to facilitate mass production. General manufacturing conducted by conventional solid-state calcination using lithium source and cobalt oxide with stoichiometric calculation. To enhance the rate capability of electrode material, there are several methods such as coating, doping and down-sizing representatively. Herein, we tried to develop the LiCoO2 material showing stable charge rate performance at high rate. The single crystal with big size morphology usually has good electric conductivity and relatively lower ionic conductivity. In contrast, polycrystalline shows vice versa. Therefore, in this experiment we suggested the spherical secondary particle to secure porosity and better tap density compared to existing down-sized particles at the same time.ope

Factores de riesgo asociado al sobrepeso y obesidad en adolescentes de la Institución Educativa INIF 48, Sullana 2024

La presente investigación se elaboró con el objetivo de determinar los factores de riesgo asociados a la presencia del sobrepeso y obesidad en adolescentes de la Institución Educativa INIF 48 - Sullana. La metodología fue de tipo básica y no experimental, donde participaron 164 adolescentes femeninas de 1ero a 5to de secundaria de la provincia de Sullana, cuyo rango de edad fue entre 12 a 18 años, obtenidas a través de un muestreo probabilístico aleatorio. Se obtuvo que el 49% de estudiantes con IMC no elevado sí realizan actividad física, y el 26% de estudiantes con IMC elevado, no. Además, el 38%, 41% y 40% de estudiantes con IMC no elevado sí consumen alimentos energéticos, constructores y reguladores respectivamente. Por otro lado, la actividad física es un factor de riesgo asociado, lo que significa que mientras menos se realiza, mayor son las posibilidades de tener un IMC elevado. Por último, los estudiantes que consumen baja proporción de alimentos constructores en su ausencia o menor consumo, también lo generan. En conclusión, los factores de no actividad física y baja proporción de alimentos constructores se asocian en la presencia del sobrepeso y obesidad en adolescentes

Supergravity brane worlds and tachyon potentials

We study massless and massive graviton modes that bind on thick branes which are supergravity domain walls solutions in $D$-dimensional supergravity theories where only the supergravity multiplet and the scalar supermultiplet are turned on. The domain walls are bulk solutions provided by tachyon potentials. Such domain walls are regarded as BPS branes of one lower dimension that are formed due to tachyon potentials on a non-BPS D-brane.Comment: RevTex4, 6 pages; version to appear in Phys. Rev.

Detección mediante sensoramiento remoto de recursos no metálicos calcáreos en el distrito de La Encañada, Cajamarca - 2020

La región Cajamarca tiene en sus rocas y minerales industriales, un significativo valor económico para su desarrollo, sin embargo, el interés por los yacimientos calcáreos ha sido relegado a un segundo plano debido, principalmente, a la producción tradicional de los minerales metálicos tales como el oro, esto condicionó el desarrollo de nuevas técnicas de mapeo. Es por ello que la presente investigación tiene como objetivo principal detectar mediante nuevas técnicas como el sensoramiento remoto, recursos no metálicos calcáreos en el distrito de La Encañada, teniendo como hipótesis del estudio que el sensoramiento remoto detectará recursos no metálicos calcáreos, asociadas a formaciones calcáreas como Cajamarca y Celendín, la metodología utilizada en la investigación fue de enfoque cuantitativo, de tipo aplicado y sub tipo tecnológico, con diseño no experimental, transversal y correlacional, obteniéndose como principales resultados que los recursos no metálicos calcáreos, están asociados a minerales como calcita y dolomita en formaciones calcáreas como Cajamarca, Celendín, Quilquiñan mujarrum y Pariatambo; detectándose mediante el uso de sensores remotos , 3 zonas de interés prospectivo en el distrito de La Encañada, estas zonas se analizaron por medio del método MTMF y corresponden a la mayor acumulación de pixeles puros asociados a calcita y dolomita, ubicadas en zonas cercanas a concesiones no metálicas como: Quinuapampa, Quinuamayo, Huamancaga, Sangal y Patarume.The Cajamarca region has in its rocks and industrial minerals, a significant economic value for its development, however, the interest in calcareous deposits has been relegated to the background, mainly due to the traditional production of metallic minerals such as gold, this conditioned the development of new mapping techniques. That is why the main objective of this research is to detect non-metallic calcareous resources in the district of La Encañada, using new techniques such as remote sensing, with the hypothesis of the study that remote sensing will detect calcareous non-metallic resources, associated with calcareous formations. such as Cajamarca and Celendín, the methodology used in the research was of a quantitative approach, of an applied type and a sub-technological type, with a non-experimental, cross-sectional and correlational design, obtaining as main results that non-metallic calcareous resources are associated with minerals such as calcite and dolomite in calcareous formations such as Cajamarca, Celendín, Quilquiñan mujarrum and Pariatambo; Detecting through the use of remote sensors, 3 areas of prospective interest in the district of La Encañada, these areas were analyzed using the MTMF method and correspond to the highest accumulation of pure pixels associated with calcite and dolomite, located in areas close to concessions non-metallic such as: Quinuapampa, Quinuamayo, Huamancaga, Sangal and Patarume
