Phytoplankton dynamics of the river nene, England
Get PDFThe distribution of suspended algae was investigated in a 69-km length of a small lowland river in the UK, the Nene (annual median discharge at km 91.7 =6 m(^3) s(^-1). Variations in chlorophyll a data collected between 1975 and 1998 by water management organisations at km 91.7 were evaluated against a range of physical and chemical variables. Interpretation was aided by additional sampling between 1993 and 1997.The latter half of the 24-year period had significantly higher temperatures and sunshine-hours and significantly lower ammonium concentrations. Discharge, temperature and sunshine-hours were significant predictors of chlorophyll concentration, particularly between January and June, and spring chlorophyll maxima ranged from 106 to 276 µg L(^-1).Centric diatoms were the most abundant taxa in the main-river and, in the absence of other limiting factors, appeared to be restricted by the availability of silica. There was also evidence that the centric diatoms suffered from severe parasitism. Inter-year phytoplankton abundance was most variable in the summer, and years with abundant submerged macrophytes had particularly low phytoplankton numbers. Spring phytoplankton peaks occurred earlier and had smaller amplitude at downstream sites than those further upstream. Average spring chlorophyll concentrations (April - June) increased significantly between km 22.4 and km 43.9, thereafter remaining high to km 91.7. Spatial trends were attributed to changes in channel morphology, retention time, dead zones, longitudinal variations in current velocity, temperature and silica limitation. An appraisal of the Utermöhl method of counting phytoplankton was made and a new technique proposed, called 'spaced fields'. The spaced fields method accurately identified small changes in phytoplankton abundance and was used to identify short-term temporal and small-scale spatial trends in the Nene

Reassociation kinetics-based approach for partial genome sequencing of the cattle tick, Rhipicephalus (Boophilus) microplus
Get PDFBackground: The size and repetitive nature of the Rhipicephalus microplus genome makes obtaining a full genome sequence fiscally and technically problematic. To selectively obtain gene-enriched regions of this tick's genome, Cot filtration was performed, and Cot-filtered DNA was sequenced via 454 FLX pyrosequencing.Results: The sequenced Cot-filtered genomic DNA was assembled with an EST-based gene index of 14,586 unique entries where each EST served as a potential "seed" for scaffold formation. The new sequence assembly extended the lengths of 3,913 of the 14,586 gene index entries. Over half of the extensions corresponded to extensions of over 30 amino acids. To survey the repetitive elements in the tick genome, the complete sequences of five BAC clones were determined. Both Class I and II transposable elements were found. Comparison of the BAC and Cot filtration data indicates that Cot filtration was highly successful in filtering repetitive DNA out of the genomic DNA used in 454 sequencing.Conclusion: Cot filtration is a very useful strategy to incorporate into genome sequencing projects on organisms with large genome sizes and which contain high percentages of repetitive, difficult to assemble, genomic DNA. Combining the Cot selection approach with 454 sequencing and assembly with a pre-existing EST database as seeds resulted in extensions of 27% of the members of the EST database
Nene Hawaiian goose, Haleakala, Maui, Hawaii 1979
No full textThe endangered *Nene*Hawaiian goose (*Branta sandvicensis*) is endemic to Hawaii. A distant relative of the Canada goose, the feet of the *nene* have adapted to the volcanic landscape by having lost most of their webbing. The *Nene* was brought back from the verge of extinction in the 1950s by captive breeding and release programs. Today there are wild populations on the island of Hawaii (Hawaii Volcanoes National Park), Maui (Haleakala National Park), and the lowlands of Kauai. This image shows two *nene* geese in the Paliku camp grounds at the head of Kaupo Gap, on the eastern side of Haleakala National park, East Maui
Empresa Nene Gas
No full textProyecto fin de máster (Magíster en Dirección de Recursos Humanos y Habilidades Directivas)La Empresa Nene Gas desarrolla su actividad comercial en la ciudad de Curicó,
Región del Maule, desde su creación en el año 2001, se ha dedicado a la
comercialización domiciliaria de gas licuado en el formato de cilindros para la
empresa Abastible, los productos comercializados son cilindros de gas: de 5 kilos,
11 kilos, 15 kilos y 45 kilos.
Desde el año 2020, ha enfrentado una serie de inconvenientes referente a la
retención de personal, el Gerente General de Nene Gas, nos indica que ha
presentado rotación de personal para el cargo de vendedor-comisionista; el
administrador atribuye que esta rotación ha afectado las ventas de Nene Gas (Anexo
N°1, Análisis de Ventas Nene Gas periodo 2019-2022), también nos menciona que
el puesto laboral afectado es clave dentro de la organización y por ende la
preocupación de la administración de Nene Gas, quienes han buscado la causal de
la baja retención, pero le ha sido muy complejo identificar la causa debido a las
externalidades que ha enfrentado la empresa; como la pandemia del Covid.19, la
inflación, nuevas regulaciones de la superintendencia de combustible y los
fluctuantes precios que ha experimentado el valor del gas licuado
domiciliario.(García, N. 2021 Antecedentes del mercado de gas residencial en Chile).
En la actualidad Nene Gas, tiene 13 trabajadores, quienes están divididos en 3 áreas;
área comercial, área operacional y área administrativa/RRHH.
Es fundamental conocer la causa de la baja permanencia en la empresa de los
colaborares del área de ventas e intervenir de ser necesario, para mantener el
funcionamiento de las operaciones comerciales de esta empresa.
Como estudiantes del Magister en Dirección de Recursos Humanos y Habilidades
Directivas, vamos a realizar un estudio y análisis para enfrentar la problemática de
esta empresa
