Green's relations, regularity and abundancy for semigroups of quasi-onto transformations

Let V be an infinite-dimensional vector space and for every infinite cardinal n such that n≤dimV, let AE(V,n) denote the semigroup of all linear transformations of V whose defect is less than n. In 2009, Mendes-Gonçalves and Sullivan studied the ideal structure of AE(V,n). Here, we consider a similarly-defined semigroup AE(X,q) of transformations defined on an infinite set X. Quite surprisingly, the results obtained for sets differ substantially from the results obtained in the linear setting.

Filamentous fungi occurrence in free water and biofilms from drinking water storage tanks

In some regions of Brazil, especially where the water is scarce, drinking water is stored in water storage tanks. This practice gives the consumer the guarantee of available water. The water storage conditions such as the exposure to hot weather when the tanks are on rooftops allow the development of microorganisms and microbial biofilms which can deteriorate the water quality and increase the risk to human health [1,2]. This study describes the filamentous fungi (FF) detected in free water and biofilms in drinking water storage tanks in Recife - Pernambuco, Brazil. Five sampling times in triplicate were performed at two distinct points. Colony-forming units (CFU) of FF fungi were determined with 0.45 μm filtration membranes using peptone glucose rose Bengal agar (PGRBA). From the 30 samples analysed a total of 1136 CFU were obtained. The water biofilms were collected from samplers consisting of polyethylene coupons, previously installed in the reservoirs. These coupons were transferred to PGRBA plates and incubated using with the same conditions described for free FF. For the in situ detection of FF in biofilms the Calcofluor White staining technique was used. This procedure demonstrated FF forming biofilms on the surfaces of the coupons. Brazilian legislation does not define limits for FF in drinking water. However considering the potential risk of fungal contamination, the data obtained in this study will contribute to developing future quantitative and qualitative parameters for the presence of fungi in drinking water distribution systems in Brazil.

24-h urinary free cortisol from mid-pregnancy to 3-months postpartum: gender and parity differences and effects

Background: Pregnancy and postpartum have been associated to several physiological changes;however, empirical evidence was almost exclusively obtained in primiparous women and few studies focus on hormonal changes in men and second-time parents. The main aim of this study is to examine 24-h urinary free cortisol from mid-pregnancy to 3-months postpartum, comparing women/men and first/second-time parents.Methods: Twenty-six women and 22 men (N = 48) were recruited from an antenatal obstetric unit in Porto, Portugal. 24-h urinary free cortisol was measured at the 2nd and 3rd trimester and at 3-months postpartum. Repeated measures analyses of variance were conducted, in order to analyze 24-h urinary free cortisol patterns of change over this period. Gender and parity were included in the analyses as potential modifiers, in order to compare women and men, and first-and second-time parents.Results: An increase from the 2nd to the 3rd trimester (p = .006) and a decrease from the 3rd trimester to 3-months postpartum (p = .005) were reported in all parents’ 24-h urinary free cortisol. The interaction effects for Time * Gender (p = .03) and Time * Parity (p = .02) were found. Women and first-time parents revealed higher levels, while men and second-time parents showed lower 24-h urinary free cortisol levels at the 2nd trimester than at 3-months postpartum.Conclusions: Findings appear to clarify the direction, as well as, the timing, gender and parity extension of 24-h urinary free cortisol changes from mid-pregnancy to 3-months postpartum.The same pattern of change in all parents’ 24-h urinary free cortisol from mid-pregnancy to 3-months postpartum is consistent with the proposed role of hormones in preparation to parenting.

Modelo integrado de cuantificación del nivel de significación y de asignación del error tolerable en procesos de auditoría de estados contables

El objetivo que persigue un proceso de auditoría de estados contables es la comunicación por parte del auditor de una conclusión en relación al grado de razonabilidad con que tales estados reflejan la situación patrimonial, económica y financiera del ente de acuerdo a los criterios plasmados en las normas contables de referencia a ser utilizadas. El hecho que un auditor emita una conclusión errónea como consecuencia de su labor puede implicar la asunción de responsabilidades profesionales, civiles y penales como consecuencia de reclamos de usuarios de los estados contables que pudieran haberse visto perjudicados como consecuencia de la emisión de la conclusión errónea. Las normas contables a nivel nacional e internacional admiten la existencia de errores u omisiones en la información contenida en los estados contables, en la medida que tales desvíos no provoquen en los usuarios interesados en tales estados una decisión distinta a la que tomarían en caso de no existir los errores u omisiones aludidos. De lo expuesto en el párrafo anterior surge la cabal importancia que la determinación del nivel de significación total (nivel de desvíos admitidos por los usuarios de los estados contables en la información por ellos contenida) adquiere en los procesos de auditoría, como así también la asignación de tal nivel entre los distintos componentes de los estados contables (asignación del error tolerable) a los efectos de que los auditores eviten asumir responsabilidades de índole profesional, civil y/o penal. Hasta el momento no se conoce la existencia de modelos matemáticos que respalden de modo objetivo y verificable el cálculo del nivel de significación total y la asignación del error tolerable entre los distintos elementos conformantes de los estados contables. Entendemos que el desarrollo e integración de un modelo de cuantificación del nivel de significación total y de asignación del error tolerable tiene las siguientes repercusiones: 1 – Representaría para el auditor un elemento que respalde el modo de cuantificación del nivel de significación y la asignación del error tolerable entre los componentes de los estados contables. 2 – Permitiría que los auditores reduzcan las posibilidades de asumir responsabilidades de carácter profesional, civil y/o penales como consecuencia de su labor. 3 – Representaría un principio de avance a los efectos de que los organismos emisores de normas de auditoría a nivel nacional e internacional recepten elementos a los efectos de fijar directrices en relación al cálculo del nivel de significación y de asignación del error tolerable. 4 - Eliminaría al cálculo del nivel de significación como una barrera que afecte la comparabilidad de los estados contables.

Las transformaciones de la burocracia provincial: capacidades del Estado en la provincia de Córdoba. Transformations of provincial bureaucracy: State´s capacities in the province of Córdoba.

A partir de las políticas de descentralización llevadas adelante en Argentina desde la década de los ochenta, las provincias han adquirido desde entonces una importante serie de nuevas funciones lo cual las ha obligado a ampliar y diversificar sus estructuras burocráticas y administrativas. Lo que este proyecto busca abordar es un análisis de las transformaciones ocurridas durante los últimos veinte años en la organización burocrática del estado provincial en Córdoba. El proyecto pretende indagar dos aspectos de la organización burocrática: por un lado, el diseño organizacional institucional (leyes de Ministerios) y la división del trabajo que ello implica; y por otro lado, los principales procesos administrativos transversales que articulan funcionalmente las diferentes áreas de la burocracia provincial (administración financiera y recursos humanos). A partir de ello nos interesa poner en relación estas transformaciones con los cambios que va experimentando la agenda gubernamental. Suponemos, en este sentido, que los cambios organizacionales responden a cambios en dicha agenda y a la relación de fuerzas políticas que va implícita en la conformación de las mismas. De este modo, nuestra hipótesis plantea que los cambios organizaciones generados por la transformación de las agendas se manifiestan de forma más inmediata en la dimensión del diseño organizacional, mientras que los procesos administrativos transversales experimentan cambios más graduales y no necesariamente vinculados a las transformaciones de la primera dimensión. El objetivo general es analizar las transformaciones de la Administración Pública Provincial (APP) en la provincia de Córdoba, a través de dos dimensiones (el diseño de la organización burocrática y los procesos administrativos transversales), desde el retorno a la democracia (1983) a la actualidad. La investigación será realizada a la luz de posturas epistemológicas y metodológicas que en las ciencias sociales sustentan la triangulación de métodos. Recurriremos tanto a fuentes documentales y estadísticas para reconstruir el proceso de transformación de la APP, como a entrevistas semiestructuradas con actores claves para indagar sobre las dimensiones identificadas en el proyecto. Se encuadra en lo que metodológicamente se denomina "estudio de caso". La investigación permitirá fortalecer el estudio de la administración y las organizaciones públicas, lo que representa una tarea altamente significativa (y necesaria) para el mejoramiento del sector público y las necesidades de la ciudadanía. El impacto esperable es la explicitación y sistematización de las transformaciones del aparato burocrático, que puedan ser observadas, mejoradas y desarrolladas por el conjunto de las carteras ministeriales, y la confección de estrategias y tecnologías de gestión que permitan incrementar las capacidades de la administración pública provincial en la realización de las políticas y la resolución de los problemas sociales.

Optimisation of a surface mount technology process using a SnAgCu lead-free alloy

The impending introduction of lead-free solder in the manufacture of electrical and electronic products has presented the electronics industry with many challenges. European manufacturers must transfer from a tin-lead process to a lead-free process by July 2006 as a result of the publication of two directives from the European Parliament. Tin-lead solders have been used for mechanical and electrical connections on printed circuit boards for over fifty years and considerable process knowledge has been accumulated. Extensive literature reviews were conducted on the topic and as a result it was found there are many implications to be considered with the introduction of lead-free solder. One particular question that requires answering is; can lead-free solder be used in existing manufacturing processes? The purpose of this research is to conduct a comparative study of a tin-lead solder and a lead-free solder in two key surface mount technology (SMT) processes. The two SMT processes in question were the stencil printing process and the reflow soldering process. Unreplicated fractional factorial experimental designs were used to carry out the studies. The quality of paste deposition in terms of height and volume were the characteristics of interest in the stencil printing process. The quality of solder joints produced in the reflow soldering experiment was assessed using x-ray and cross sectional analysis. This provided qualitative data that was then uniquely scored and weighted using a method developed during the research. Nested experimental design techniques were then used to analyse the resulting quantitative data. Predictive models were developed that allowed for the optimisation of both processes. Results from both experiments show that solder joints of comparable quality to those produced using tin-lead solder can be produced using lead-free solder in current SMT processes.
