Water Quality Monitoring Report - 2005-2009 Monitoring of Prairie Pothole Wetlands

Prior to European settlement, wetland basins covered 4 to 6 million acres, or approximately 11% of Iowa's surface area. Wetlands were part of every watershed in the state, but nearly 95% of them have been drained for agriculture. As Iowa was settled wetlands were drained and developed, resulting in the loss of wildlife habitat, damage to water quality, rapid topsoil erosion, and increased incidents and severity of flooding. The condition of Iowa’s remaining wetlands is poorly known. The goal of this project was to assess the ecological condition of prairie pothole wetlands in a defined region of north-central Iowa. This project has worked to develop and establish our wetland sampling methods, while providing baseline data regarding the basic chemical, physical, and biological status of Iowa’s permanent and semi-permanent wetland resources. The baseline data obtained from our monitoring methods is mainly in the form of numerical values derived from the lab analyses of our samples. This data will be used to begin building a database to interpret ecological condition changes in Iowa’s wetlands as the sampling regime and assessment methodology are repeated over time.

Applying the Total Quality Management Method in ICT Business

Kokonaisvaltaisen laatujohtamisen malli TQM (Total Quality Management) on noussut yhdeksi merkittävimmistä konsepteista globaalissa liiketoiminnassa, missä laatu on tärkeä kilpailutekijä. Tämä diplomityö pureutuu nykyaikaiseen kokonaisvaltaisen laatujohtamisen konseptiin, joka nostaa perinteisen laatuajattelun uudelle tasolle. Moderni laatujohtamisajattelu on kasvanut koskemaan yrityksen toiminnan kaikkia osa-alueita. Työn tavoitteena on TietoEnator Käsittely ja Verkkopalvelut liiketoiminta-alueen osalta laadun sekä liiketoiminnallisen suorituskyvyn parantaminen kokonaisvaltaisesti. Ennen varsinaisen laatujohtamis-konseptin käsittelyä työ esittelee ensin yleisellä tasolla perinteistä laatu käsitettä sekä käsittelee lyhyestiICT-liiketoimintaa ja siihen liittyviä standardeja. Lopuksi tutkimus esittelee priorisoituja parannusehdotuksia ja askeleita jotka auttavat organisaatiota saavuttamaan kokonaisvaltaisen laatujohtamiskonseptin mukaisia pyrkimyksiä.

A Semantic wiki for quality management in software development projects

Quality management has become a strategic issue for organisations and is very valuable to produce quality software. However, quality management systems (QMS) are not easy to implement and maintain. The authors' experience shows the benefits of developing a QMS by first formalising it using semantic web ontologies and then putting them into practice through a semantic wiki. The QMS ontology that has been developed captures the core concepts of a traditional QMS and combines them with concepts coming from the MPIu'a development process model, which is geared towards obtaining usable and accessible software products. Then, the ontology semantics is directly put into play by a semantics-aware tool, the Semantic MediaWiki. The developed QMS tool is being used for 2 years by the GRIHO research group, where it has manages almost 50 software development projects taking into account the quality management issues. It has also been externally audited by a quality certification organisation. Its users are very satisfied with their daily work with the tool, which manages all the documents created during project development and also allows them to collaborate, thanks to the wiki features.

Community structure and water quality in Mediterranean streams of a Natural Park (Sant Llorenç del Munt, NE Spain)

Se estudian las comunidades de macroinvertebrados de los ríos del Parque Natural de Sant Llorenç del Munt i la Serra de l'Obac (Barcelona, NE España) y su relación con las condiciones de flujo de los ríos. Hasta 78 localidades se visitaron en dos ocasiones (invierno y verano de 1996) y en 26 de ellas se tomaron muestras de macroinvertebrados. Mientras en invierno el 63 % de los kilÛmetros investigados tenía flujo continuo y menos del 1% estaba seco, en verano solo el 26% tenía flujo continuo, un 20% estaba totalmente seco y el resto presentaba pozas en su lecho. A pesar de ello el número de familias de macroinvertebrados fue de 54 en invierno y 94 en verano, siendo dominantes en este último caso los heterópteros, coleópteros, odonatos y dípteros, mientras que en invierno los tricópteros y plecópteros eran más diversos. En general, la comunidad presentó una estrategia trófica recolectora aunque la proporción de los ramoneadores y depredadores aumentó en verano. El estudio de las comunidades mediante el análisis de su abundancia en los dos perÌodos, mostró que las variables temporales (flujo, temperatura) o las relacionadas con el incremento de la producciÛn primaria (oxÌgeno, pH) explicaban la mayor parte de la variabilidad con los elementos mas reófilos propios de invierno y los leníticos de verano, mientras que otros factores fisicoquímicos no eran relevantes. Calculado el índice biológico BMWP' se demostró que los valores en verano eran superiores o similares a los de invierno lo que se explica por la mayor diversidad aunque la calificaciÛn individual de cada una de las familias encontradas en verano fuera menor que las halladas en invierno.
