THE IMPACTS OF ATMOSPHERICALLY DERIVED METALS ON COASTAL MARINE SYSTEMS

The total concentrations of trace metals (Al, Fe, Mn, Co, Na, Cu, Zn, Mo, Ni, V, Cd, Pb) have been determined in the marine aerosol at two contrasting coastal sites, Plymouth UK, (December 2001 to April 2003) and Jeddah, Saudi Arabia (August 2002-January 2004). Trace metal concentrations in the Plymouth urban aerosol were lower (2-13 times) than those observed at other comparative UK. urban locations and generally comparable with those observed at European coastal non-urban locations. Statistically significant differences were found in aerosol metal concentrations associated with populations of contrasting air mass sources (i.e. Atlantic and UK/European), being greatest in the UK/European air mass sector for Al, Fe, Mn, Cd, Mo and Pb, owing to enhanced source emission rates from continental Europe. Based on the current work, refined budgets for Ni and Pb for the English Channel were presented. The budgets clearly indicated the importance of the English Channel sediments as both a sink (Ni) and a source (Pb). Aerosol concentrations in the Red Sea Marine Aerosol (RSMA) for the crustally sourced elements Al, Mn and Fe were higher (typically 2.7-3.1 times) than those detected at other comparative sites (i.e. Eastern Mediterranean). The aerosol population associated with the Middle and Southern Saudi Arabia (SSA) air mass had the greatest concentrations of Al, Fe, Mn and Co, whereas, the lowest were found associated with the open Red Sea (RS) marine aerosol. Summer enhancement of aerosol metals was attributed to seasonal dust resuspension as documented in the literature. Red Sea trace metal budgets were presented and would suggest that the sediments are an important source for all elements to the Red Sea water column except for Co and Cd. This work has, therefore, provided unique insights into influences on the air/sea exchange of trace metals and their subsequent impacts and fates in two contrasting marine systems

Spectral analysis of the spin-boson Hamiltonian with two photons for arbitrary coupling

We study the spectrum of the spin-boson model with two photons in $\mathbb{R}^d$ for arbitrary coupling $\alpha>0$. It is shown that the discrete spectrum is finite and the essential spectrum consists of a half-line the bottom of which is a unique zero of a simple Nevanlinna function. Besides the simplicity and more abstract nature of our approach, the main novelty is the achievement of these results under "minimal" regularity conditions on the photon dispersion and the coupling function.Comment: 16 page

Correlation the Components of Social Intelligence with Other Types of Intelligence in Person’s Maturity

In the research of the world level we can see that the main issue of the problem of personality development is aimed at determining the types, indicators and criteria of development. In these research works, the authors propose various methodological tools for diagnosing personality maturity. Although foreign and Uzbek scientists have conducted research on the factors and problems that affect the psychological aspects of personal development, the relevant correlation between the level of person’s education attainment and acquiring a qualification and profession at different ages, the level of development in different periods of career activity and determinant of social intelligence has not been studied as an object of special scientific research. Hence, it is important to study and research the formation of new types of personality development in modern life, the manifestation and development of social intellectual activity of a person. The article construes an experimental study of the correlation of social intelligence with other types of intelligence in personality maturity. It presents the analysis of students' general and social intelligence indicators, as well as the psychological analysis of relationship indicators of female and male students’ social intelligence with other types of intelligence. According to the results of the research, the processes of social intelligence of students have more obvious correlations in relation to the progression of general intelligence, and they have been found to have differences according to the gender differences of the entity

Sharp spectral bounds for complex perturbations of the indefinite Laplacian

We derive quantitative bounds for eigenvalues of complex perturbations of the indefinite Laplacian on the real line. Our results substantially improve existing results even for real-valued potentials. For $L^1$-potentials, we obtain optimal spectral enclosures which accommodate also embedded eigenvalues, while our result for $L^p$-potentials yield sharp spectral bounds on the imaginary parts of eigenvalues of the perturbed operator for all $p\in[1,\infty)$. The sharpness of the results are demonstrated by means of explicit examples.Comment: References added before Theorem 2 and

Planificación del proyecto electrocloración del reactor EPR en Flamanville

Planificar el proyecto es la clave para tener una dirección clara de lo que se debe hacer. El objetivo es de cumplir a tiempo el contrato que hemos firmado para el cliente final. Para tener una mejor visión del proyecto, se ha utilizado la herramienta EDT. Permite de cortar el proyecto en sub-proyectos, definiendo un número de etapas a seguir, para alcanzar el objetivo final. El proyecto de planificación de válvulas reguladas ha permitido de aplicar este método, y ver el resultado de su utilización. He definido, las etapas que tenían un orden lógico para ser realizadas las unas después las otras, y que podían ser bien valoradas. Gracias al diagrama de GANTT, hemos planificado estas etapas, definidas por el método EDT, poniendo fechas de comienzo y final. Sin embargo, el factor humano y todas las personas implicadas en el proyecto general, han hecho que hemos tenido muchísimo retraso sobre lo que era previsto. Pero las herramientas de planificación que hemos utilizadas, nos permitieron de reaccionar rápidamente, y de cambiar las fechas. Además, gracias a esta separación en sub-etapas, podía ver las consecuencias sobre las otras etapas y actuar en consecuencia. Mirando si no se podía adelantar un hito para recuperar el tiempo perdido sobre otro. La planificación no se debe resumir al único momento de gestión al principio del proyecto, es también el seguimiento y la reacción a lo largo del tiempo. El método de Estructura de Desglose del Trabajo es muy eficiente para eso, porque permite de controlar en más pequeñas partes, que son más sencillas a controlar. Pero se debe tener cuidado en el desglose, que no hay demasiado etapas, sino empieza a ser imposible de controlar el proyecto. Esta herramienta es muy útil, permite de reaccionar rápidamente en caso de problema en el respeto de las fechas contractuales definidas al principio del proyecto. Una buena gestión de la planificación permite a un proyecto de alcanzar su objetivo final de manera organizada, eficiente y con calidad. Sin embargo, no se debe olvidar el factor humano dentro de esta ecuación, para planificar el proyecto de manera que sea el más plausible.Ingeniería Industria
