This thesis Entitled Biology of Decapod crustaceans in different Environmental conditions. Prawn culture is practiced in Kerala in two types of fields namely seasonal and perennial; In seasonal fields paddy is grown during the monsoon period and prawns are cultured during the rest of the year. when compared to seasonal fields; perennial fields are subjected to much fluctuations in its environmental characteristics. The perennial fields were found more productive than seasonal fields. The benthic production in perronial fields were almost double that of seasonal fields. But in the matter of species diversity both fields were equal. Seasonal changes were observéd in the species abundance of benthic organisms in both the seasonal and perennial fields. Both isometric and allometric growth were noticed in P. indicus .But during most of the months the growth was near to isometric. The condition of the prawn also fluctuated between better and poor.During most of the months the prawn in perennial fields wore in good condition while in the seasonal fields the condition changed from year to year. This indicates that the perennial field provides a better habitat for P. indicus.

Organisational commitment of various groups of professionals seems to be moderated by the differences of the groups as well as of the socialisation experiences Demographic variable ‘age’ and the semi-structural variable ‘experience’ cause a difference in the level of commitment. Similarly, the professional and organisational differences moderate the level of commitment. From the point of view of the organisations, the socialisation experiences if differ can be used as tool to process and enhance the level of commitment of professionals of various groups.The ‘Socialisation effect’ does not depend on the professional or demographic differences. Socialisation level is moderated only by the organisational specialities. It is purely an organisational variable. However, the difference in the socialisation levels as found among the professionals can cause a significant difference in the levels of organisational commitment of professionals

The nearshore marine ecosystem is a dynamic environment impacted by many activities, especially the coastal waters and sediments contiguous to major urban areas. Although heavy metals are natural constituents of the marine environment, inputs are considered to be conservative pollutants and are potentially toxic, accumulate in the sediment, are bioconcentrated by organisms and may cause health problems to humans via the food chain. A variety of metals in trace amounts are essential for biological processes in all organisms, but excessive levels can be detrimental by acting as enzyme inhibitors. Discharge of industrial wastewater, agriculture runoff and untreated sewage pose a particularly serious threat to the coastal environment of Kerala, but there is a dearth of studies in documenting the contaminant metals. This study aimed principally to assess such contamination by examining the results of heavy metal (Cu, Pb, Cr, Ni, Zn, Cd and Hg) analysis in seawater, sediment and benthic biota from a survey of five transects along the central and northern coast of Kerala in 2008 covering a 10.0 km stretch of near shore environment in each transect. Trophic transfer of metal contaminants from aquatic invertebrates to its predators was also assessed, by employing a suitable benthic food chain model in order to understand which all metals are undergoing biotransference (transfer of metals from a food source to consumer).The study of present contamination levels will be useful for potential environmental remediation and ecosystem restoration at contaminated sites and provides a scientific basis for standards and protective measures for the coastal waters and sediments. The usefulness of biomonitor proposed in this study would allow identification of different bioavailable metals as well as provide an assessment of the magnitude of metal contamination in the coastal marine milieu. The increments in concentration of certain metals between the predator and prey discerned through benthic food chain can be interpreted as evidence of biotransference.

In the present study diversity of E. coli in the water samples of Cochin estuary were studied for a period of 3 years ranging from January 2010- December 2012. The stations were selected based on the closeness to satellite townships and waste input. Two of the stations (Chitoor and Thevara) were fixed upstream, two in the central part of the estuary namely Bolgatty and Off Marine Science Jetty, and one at the Barmouth. Diversity was assessed in terms of serotypes, phylogenetic groups and genotypes. Two groups of seafood samples such as fish and shellfish collected from the Cochin estuary were used for isolation of E. coli. One hundred clinical E. coli isolates were collected from one public health centre, one hospital and five medical labs in and around Cochin City, Kerala. From our results it was clear that pathogen cycling is occurring through food, water and clinical sources. Pathogen cycling through food is very common and fish and shellfish that harbour these strains might pose potential health risk to consumer. Estuarine environment is a melting pot for various kinds of wastes, both organic and inorganic. Mixing up of waste water from various sources such as domestic, industries, hospitals and sewage released into these water bodies resulting in the co-existence of E. coli from various sources thus offering a conducive environment for horizontal gene transfer. Opportunistic pathogens might acquire genes for drug resistance and virulence turning them to potential pathogens. Prevalence of ExPEC in the Cochin estuary, pose threat to people who use this water for fishing and recreation. Food chain also plays an important role in the transit of virulence genes from the environments to the human. Antibiotic resistant E. coli are widespread in estuarine water, seafood and clinical samples, for reasons well known such as indiscriminate use of antibiotics in animal production systems, aquaculture and human medicine. Since the waste water from these sources entering the estuary provides selection pressure to drug resistant mutants in the environment. It is high time that the authorities concerned should put systems in place for monitoring and enforcement to curb such activities. Microbial contamination can limit people’s enjoyment of coastal waters for contact recreation or shellfish-gathering. E. coli can make people sick if they are present in high levels in water used for contact recreation or shellfish gathering. When feeding, shellfish can filter large volumes of seawater, so any microorganisms present in the water become accumulated and concentrated in the shellfish flesh. If E. coli contaminated shellfish are consumed the impact to human health includes gastroenteritis, urinary tract infections (UTIs), and bacteraemia. In conclusion, the high prevalence of various pathogenic serotypes and phylogenetic groups, multidrug-resistance, and virulence factor genes detected among E. coli isolates from stations close to Cochin city is a matter of concern, since there is a large reservoir of antibiotic resistance genes and virulence traits within the community, and that the resistance genes and plasmid-encoded genes for virulence were easily transferable to other strains. Given the severity of the clinical manifestations of the disease in humans and the inability and/or the potential risks of antibiotic administration for treatment, it appears that the most direct and effective measure towards prevention of STEC and ExPEC infections in humans and ensuring public health may be considered as a priority.

La progressiva creació de l'Espai Europeu d'Educació Superior porta la Universitat de Girona a un procés de reflexió i renovació de l'organització acadèmica i docent dels estudis. Volem que la societat gironina participi activament en la definició de les noves titulacions que han d'oferir la formació adequada perquè els estudiants assoleixin amb èxit les competències professionals que el món laboral demana. Aquestes pàgines tenen l'objectiu de divulgar, a grans trets, el perquè, el què, el com i el quan de la reforma de l'educació superior que estem començant

En aquest treball es volen avaluar els resultats obtinguts en la implantació de l’avaluació continuada i particularment de l’eina informàtica ACME (Avaluació Continuada i Millora de l’Ensenyament) en dues assignatures de química de primer curs corresponents als estudis de Química i Ciències Ambientals de la UdG. A nivell d’impacte en les qualificacions obtingudes pels estudiants, s’observa un augment de la nota final entre 0,6 i 1 punt respecte a la qualificació obtinguda en l’examen final, per les dues assignatures. L’ACME permet treballar algunes competències, principalment la capacitat de resolució de problemes, competència que apareix en el disseny de les dues assignatures de Química. També permet desenvolupar altres competències com ara la capacitat de planificació i organització. Addicionalment, l’ACME és un bon sistema per l’autoavaluació del propi aprenentatge, que en definitiva és el que es persegueix amb el sistema d’avaluació continuada

El portafoli és una eina complexa i polivalent que aplicada a l’aprenentatge i avaluació dels coneixements, permet resultats molt satisfactoris en situacions molt dispars tant per la tipologia de les matèries com pels objectius docents. La utilitat del portafoli rau en el potencial per identificar habilitats i/o coneixements de l’alumne que passarien desapercebuts amb el sistema tradicional i per fomentar un aprenentatge autoreflexiu. Els tres casos que s’exposen són tres exemples d’ús del portafoli per a l’aprenentatge i l’avaluació de coneixements en l’àmbit universitari que tenen lloc en els camps de les ciències socials i de les ciències experimentals a la Universitat de Girona. Responen a tres situacions i tres objectius docents diferents. L’anàlisi d’aquests tres casos exemplifica la flexibilitat del portafoli i permet comparar els resultats en matèries i situacions dispars
