Aspectos Oceanográficos en primavera 2003: Crucero bento-dermesal BIC Humboldt 0310

El Crucero bento-demersal 0310 se desarrolló del 6 al 23 octubre 2003. Las observaciones más importantes fueron: (a) condiciones físico oceanográficas con tendencia a la normalización termohalina al norte de los 5°S, y condiciones muy próximos a lo normal hacia el sur; (b) frente ecuatorial ligeramente proyectado hacia el sur (Talara-Paita) por la presencia de aguas tropicales y ecuatoriales entre los 3°30’ y 4°30’S, zona en que se registraron anomalías térmicas hasta de +3,6 °C; (c) predominio de aguas costeras frías al sur de los 5°S con el repliegue de la ESCC y un marcado ascenso de las isotermas con respecto a lo observado en el invierno (Cr. 0308-09); (d) las secciones de Paita, Punta Falsa y Chicama mostraron desarrollo del afloramiento costero, más intenso frente a Chicama; (e) las principales capturas del recurso merluza se realizaron en las áreas C y D, bajo temperatura de 13,5 a 14,5 °C, salinidad 34,98 y 35,02 ups, y oxígeno disuelto de 0,6 a 0,8 mL/L.

Aspectos oceanográficos en primavera 2003: Crucero pelágico BIC Humboldt y Olaya 0310-12

El estudio se realizó a bordo de dos barcos y en forma simultánea: BIC Humboldt que cubrió de 100 a 200 mn y BIC Olaya, dentro de las 100 mn. Las observaciones más importantes fueron: (a) presencia de las aguas subtropicales superficiales (ASS) de Pimentel (8°S) hasta la frontera sur (18°S), con una notable advección a la costa de Huarmey (10°S), al Callao (12°S) y al sur de los 15°S (San Juan de Marcona); (b) proyección de aguas ecuatoriales superficiales (AES) hasta los 5°20’S, por el arribo de una nueva onda Kelvin; (c) registro de aguas ecuatoriales superficiales (AES) entre 6°30’ y 8°S por fuera de las 140 mn, constituyendo rezagos de las ondas que arribaron en agosto; (d) predominancia de anomalías térmicas positivas de hasta +1,5 °C, relacionadas con la persistencia de las ondas Kelvin y el relajamiento de los sistemas atmosféricos que debilitaron los vientos Alisios del sudeste, y que redujeron las áreas de afloramiento costero; (e) registro de dos pequeños núcleos con anomalías negativas.

Ictioplancton y volúmenes del zooplancton en la primavera 2003 frente a la costa peruana

Se describe la distribución y abundancia de las principales especies del ictioplancton observadas durante el crucero de primavera 2003 frente a la costa peruana. El pez portador de luces fue la especie que presentó la mayor frecuencia y la anchoveta presentó los mayores valores de abundancia. La distribución de anchoveta estuvo cerca a la costa, mientras que del pez portador de luces se localizó de acuerdo a la configuración de la plataforma continental, siendo más próxima a la costa en la zona sur. Los volúmenes de zooplancton estuvieron entre 0,5 y 40 cm3/muestra, con mayor frecuencia en el rango entre 5 y 10 cm3/muestra en el 45,3% de las estaciones.

Fitoplancton frente a la costa peruana durante en la primavera 2003

Entre octubre y diciembre 2003 se evaluó el fitoplancton de Puerto Pizarro a Ilo. Se colectó 102 muestras de red y 51 muestras de agua. En el fitoplancton de red se diferenció dos grupos de diatomeas: 1) al norte de Chancay donde especies de afloramiento y neríticas dominaron y se distribuyeron desde la costa hasta 45 mn; 2) al sur de Huacho donde predominaron diatomeas oceánicas. Las mayores concentraciones celulares se localizaron dentro de la franja costera en Paita y Chimbote con valores >3 x106 cel/L destacando Skeletonema costatum. Protoperidinium obtusum, indicador de Aguas Costeras Frías (ACF) se halló de Paita a Ilo. Ceratium breve, indicador de Aguas Ecuatoriales Superficiales (AES) se presentó frente a Puerto Pizarro por fuera de las 60 mn junto con C. praelongum indicador de Aguas Subtropicales Superficiales (ASS), lo que indicaría mezcla de estas aguas.

Dynamical evolution of the 2003 southern hemisphere stratospheric winter using Envisat trace-gas observations

Data from the MIPAS instrument on Envisat, supplemented by meteorological analyses from ECMWF and the Met Office, are used to study the meteorological and trace-gas evolution of the stratosphere in the southern hemisphere during winter and spring 2003. A pole-centred approach is used to interpret the data in the physically meaningful context of the evolving stratospheric polar vortex. The following salient dynamical and transport features are documented and analysed: the merger of anticyclones in the stratosphere; the development of an intense, quasi-stationary anticyclone in spring; the associated top-down breakdown of the polar vortex; the systematic descent of air into the polar vortex; and the formation of a three-dimensional structure of a tracer filament on a planetary scale. The paper confirms and extends existing paradigms of the southern hemisphere vortex evolution. The quality of the MIPAS observations is seen to be generally good. though the water vapour retrievals are unrealistic above 10 hPa in the high-latitude winter.

Spatial Analysis of Colby College Trails: Perkins Arboretum and Runnals Hill

I created an updated map of trails at Colby College using global positioning system data that were then edited in ArcGIS. The map background, obtained from the Maine Office of GIS, was created from digital orthophotographs produced from aerial photos collected over southwest Maine in Spring 2003. Trail difficulty was determined by creating a slope layer and taking other factors into consideration such as ground surface and path width. The map will eventually be available online, enabling interactive selection of trails where users can access additional trail information.

Avian Use of Harvested Crop Fields in North Dakota During Spring Migration

Broad-spectrum herbicide applications and improved harvesting efficiency of crops have reduced the availability of weed seeds and waste grains for game and nongame wildlife. Over the last decade, corn and soybean plantings have steadily increased in the Prairie Pothole Region (PPR) of North Dakota, while sunflower plantings have declined. The PPR is an important corridor for migratory birds, and changes in food availabilities at stopover habitats may affect how food resources are used. In early spring 2003 and 2004, we compared bird use of harvested fields of sunflower, soybeans, small grains, and corn in the PPR of North Dakota. Across both years and all crop types, we observed 20,400 birds comprising 29 species. Flocks of Lapland Longspurs (Calcarius lapponicus) and Horned Larks (Eremophila alpestris) and flocks of Red-winged Blackbirds (Agelaius phoeniceus) made up 60% and 15%, respectively, of the bird counts. We found that species richness and bird densities were higher in harvested sunflower fields and cornfields than in harvested small-grain and soybean fields, with soybean fields harboring the fewest species and lowest bird density. Blackbird densities tended to be lower in fields tilled after fall harvest than in fields not tilled. These results suggest that some granivorous bird populations in the Northern Great Plains could be positively affected by planting of row crops with postharvest vertical structure (e.g., sunflower, corn) and use of no-till land management practices.

Riskienhallinta verkostotaloudessa. Case Varenso Oy

Tutkielman avulla pyrittiin edesauttamaan kohdeyrityksen riskienhallintaa verkostotaloudessa turvallisuusnäkökulmasta. Tutkielmassa tarkasteltiin neljän alihankkijayrityksen asennetta ja menettelytapoja turvallisuusjohtamisen, organisaation, toiminnan suunnittelun, toiminnan varmistamisen, sidosryhmien, riskien hallinnan, hätä- ja poikkeustilanteiden, turvallisuuskoulutuksen, tiedonkulun ja dokumentoinnin sekä mittaamisen osa-alueilta Turvallisuus kymppi menetelmää käyttäen. Tutkielma suoritettiin syksyn 2002 ja kevään 2003 aikana. Aiheen monitahoisuuden vuoksi asiaa tarkasteltiin hankintatoimen muuttuneen roolin, verkostotalouden, riskien ja riskienhallinnan kautta. Tutkielman lopputuloksena havaittiin, että verkostossa toimittaessa keskusyrityksen ja aliurakoitsijoiden riskeistä tulee yhteisiä, eikä niitä ei voida enää kokonaan erotella. Koulutuksen, tiedonkulun, mittaamisen, riskienhallinnan ja sidosryhmien välisen toiminnan luonne korostuu entisestään.

Työhyvinvointi, koulutus ja toiminnan kehittäminen terveyskeskuksissa lääkäritilanteen näkökulmasta

Finnish health centres have suffered from a shortage of physicians in recent years. This is why more physicians are being educated, the tutelage of the young physicians has been improved and many tasks which were previously reserved for physicians have been transferred to nurses and other personnel of the health centres. Only a little research has been done about the effects of the shortage of physicians and education to the work atmosphere in the health centres The objectives of the study was to describe the situation of the physicians in the counties Satakunta and South-Western Finland at the time when the University of Turku started to decentralise its education to Satakunta and describe the health centres attitudes towards training and research co-operation with the University of Turku; to gain information about the training programmes for physicians in specific training in general medical practice (STPG); study how the shortage of physicians affects the job atmosphere, the job satisfaction and the operation of the health centres; study health centre employees opinions about their professional skills, their needs and interets in continuing education; study medical and nurse students professional indentity and their readiness to multiprofessional teamwork. The material of the study was gathered during 2003-2006 with three mail questionnaires and a questionnaire given to medical and nurse students who practised in the training health centre in Pori. The first questionnaire was sent to the chief physicians of the health centres in counties Satakunta and South-Western Finland to clarify the number of unfilled positions of physicians and the reasons for physician shortage as well as the readiness for practical training of medical students and research at the health centres. The second questionnaire was posted to doctors in specific training in general medical practice and their trainers at the health centres and it gained information about training programmes of young physicians at health centres. The third questionnaire was sent to personnel at health centres in Satakunta and South-Western Finland and included questions about job satisfaction and education. The survey for medical and nurse students gained information about their professional indentity and their readiness to multiprofessional teamwork. In spring 2003 the shortage of physicians was more severe in Satakunta than in South-Western Finland. Attitudes towards training of medical students and research co-operation with the universities were generally positive. The guidance of STGP doctors in health centres improved during 2003-2005. A shortage of physicians had only a slightly negative impact on employee job satisfaction. The shortage of physicians had also positive impact on the operation of the health centres because it led to reorganization of the operations. The personnel at Finnish health centres were willing to take more challenging tasks and also to acquire appropriate further education or training. The medical and nurse students had strong professional identity and they understood the significance of teamwork for the health care service system.
