Denna rapport handlar om hur en förbättring av projektstrukturen kan genomföras på Sweco Industry som är en del av Sweco AB. Sweco Industry är involverade i stora och många projekt och är i behov av en gemensam samt organiserad strukturmodell. För att undersöka material som finns att tillhandahålla i dagsläget söktes det efter befintliga styrdokument och intervjuer med personalen gjordes. Rapporten beskriver också hur ett referensprojekt användes som stöd för att fördjupa kunskapen om hur ett projekt genomförs. Referensprojektet genomfördes med hjälp av intervjuer som baserades på Sweco Logistics (som är en del av Sweco Industry) nuvarande strukturmodell, Lakanet, där hela processen från initiering av projektet till avslut följdes. Syftet med arbetet är att försöka identifiera eventuella brister i Sweco Logistics nuvarande strukturmodell och vad som bör förbättras. Särskilt fokus läggs på hur projektarbetet på Rustas centrallager har genomförts. Avsikten är även att ta reda på vad för material i form av styrdokument som används idag på Sweco Industry gällande projekt. Tidigt i undersökningen kunde det konstateras att det finns en förbättringspotential i hur Swecos medarbetare följer en gemensam strukturmodell. Det finns exempel där personalen har lågt medvetande om Lakanets existens vilket försvårade undersökningen, men med kontinuerliga styrgruppsmöten tydliggjordes frågetecken och intressanta observationer gjordes. Emellertid kunde det konstateras att Sweco Industry lyckas väldigt bra i projekt som de tar sig an, och det för att många av medarbetarna har sedan tidigare stor erfarenhet av att arbeta i projekt. Denna kunskap måste Sweco Industry belysa, ta vara på och använda för att utbilda framtida projektledare. Under tiden som examensarbetet pågick startades ett arbete med en ny version av strukturmodellen där examensarbetarna var högst delaktiga i utformningen då de både muntligt samt skriftligt givit förslag till hur materialet kan tänkas se ut.

In this study I investigate the Iranian Green Movement supporters' use of slogans as political discourse on the Persian-language opposition website www.kaleme.com. Data was collected from the website's Kaleme section in the form of 22 articles and 3,500 user comments. A coding scheme was constructed to measure the presence of categories and themes in the site's comments section. Findings support the propositions of narrative theorists (e.g. Franzosi, 1998; Benford, 1993) that frequent use of slogans in the comments may reflect a unique cultural element of Persian-language political discourse and reinforce the Green Movement's narrative of opposition to the government.

A culture collection of clonal, axenic cultures of 35 Arthrospira strains and five strains, which were duplicate subcultures of the original isolates, was established. In addition, eight morphological mutants were isolated from cultures of these strains. All strains are different from those belonging to the genus Spirulina as concluded from TEM and PyMS studies. All Arthrospira strains, duplicates and different morphotypes were screened for variation in morphological, ultrastructural, physiological and biochemical characters for taxonomic purposes. Special emphasis was put on the analysis of factors which influence the morphology of the trichome helix, as this is the feature most characteristic forArthrospira strains. For example, the orientation of coiling was found to be influenced by genetic drift or the growth temperature, but can also be reversed by mechanical impact. Studies were also made on the ability to utilize sugars for growth. None of the strains grew on sucrose, but many grew on glucose and/or fructose. Growth in the presence of sucrose under photoheterotrophic conditions required an adaptation process, though sucrose is not being utilized for growth. Analysis of fatty acid composition of all strains revealed quantitative differences between strains, most markedly in the unsaturated fatty acid fraction. Repeat experiments showed the same results each time, indicating the value of this approach for identification purposes. Similarly, lectin-binding to cell surface structures proved to be a useful approach for differentiation between strains. Analysis of the whole cell composition by pyrolysis mass spectrometry (PyMS) did not confirm the clusters based on other phenotypic characters, but showed that there is a high similarity between duplicate strains or different morphotypes derived from the same stock. Numerical analysis of the data for 28 characters resolved the helical strains in two phenotypic clusters which show a high correlation to the two molecular clusters based on ARDRA of the ITS of the same set of strains. The helical trichome morphology of the strains showed the highest correlation to either of the clusters. Comparison of species descriptions and morphological characters of the strains, as determined in the presented work, indicate, that phenotypic cluster I is composed of Arthrospira maxima, A. fusiformis and A. indica, while A. platensis forms phenotypic cluster II

Increasing applications of nano materials in medicine, construction, textiles, computers, and other consumer goods have lead to increasing concerns of their effect on human health and ecology during synthesis, manufacturing, use, and disposal of nano-materials. Though much scientific progress has been made in nano material synthesis, manufacturing, and application in consumer goods and other sectors such as medicine, textiles and more, not much progress has been made in understanding the adverse effects of nano materials on human health and the environment. Physical, chemical, toxicological characteristics of these nano materials and their fate in the environment are important in understanding their adverse effects on the environmental and human health. This study is aimed at developing a preliminary framework for risk assessment (RA) and risk management (RM) of nano materials based on fundamental principles of chemistry, physics, toxicology, and other related disciplines.

Hatchling marine turtles use visual cues to orient from their nest to the sea at night. However, the wavelengths of light that carry this information have not been properly documented, nor do we understand why they are favored. I measured wavelength irradiance at 20 nm intervals between 340 – 600 nm at a dark nesting beach and then, in the laboratory, determined the thresholds of the hatchlings for each λ that evoked a positive phototaxis. In this study, I show that green turtle hatchlings are (i) most sensitive to the shorter (360 – 480 nm) light wavelengths. Those light energies (ii) dominated the available natural lighting at the nesting beach. They also (iii) presented a steep gradient in irradiance between a landward and seaward view, an important cue for orientation. I attribute the phototactic responses to “stimulus filtering”, the outcome of natural selection that optimizes behavioral responses (seafinding) according to their function, as well as when and where they occur. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

Activity patterns of Iguana iguana from two locations within Hugh Taylor Birch State Park, Fort Lauderdale, Florida were documented and examined. Between May 1, 2006 to April 20, 2007, I. iguana were observed on a routine basis and activities were documented as one of six major activity categories (basking, locomotion, foraging, resting, visual signaling, and other). Data was analyzed to determine differences between activity patterns of I. iguana relative to sites, seasons, and size category within the park. Iguana iguana spent more time basking at Site 1 than Site 2. Size 4 animals which consisted of dominant adult males, spent more time basking than other males and adult females. Size 4 animals also spent less time foraging than hatchlings, juveniles, and other adults. These results complement the existing research on behavior of I. iguana and may be useful in determining invasive control efforts of I. iguana in Florida. / by Stacey R.
