Studium generování hydridů pro účely speciační analýzy arsenu spojené s AAS a AFS detekcí / Hydride generation study for arsenic speciation analysis with AAS and AFS detection

Svoboda, Milan January 2012 (has links)
The general aim of this work was a development of methodology and instrumentation for speciation analysis based on the combination of the selective generation of substituted hydrides with atomic absorption or atomic fluorescence spectrometry detection. The first topic of this work was the development of methodology and instrumentation for arsenic speciation analysis based on selective generation of substituted arsines with trapping in the cryogenic trap (U-tube packed with chromosorb) with AAS detection (HG- CT-AAS). The conditions of the selective hydride generation approach as well as working procedure of the cryogenic trap were optimized (appropriate approach for hydride generation, set up of heating program of cryogenic trap, new dryer - cartidge with NaOH, elimination of unspecific absorption, decreasing of the detection limits). The second important part of the work lay in applying of the developed method for arsenic speciation analysis in a homogenized mouse liver tissue. The direct slurry sampling to hydride generator was develop. Moreover the information about oxidation state (iAsIII,V , MAsIII,V a DMAsIII,V ) was obtain. The effect of relevant experimental parameters such as tetrahydroborate concentration, TRIS buffer concentration and time of pre-reduction of the samples by L-cysteine...

Nykonstruktion av bandställ : Nykonstruktion av bandställ för intern lagertransport med gaffeltruck / New Design for Metal Strip Carrier : New Design for Metal Strip Carrier for Transportation Inside Factory

Miles, Lukas January 2020 (has links)
Bandställ används idag för att förvara och transportera stålband hos voestalpine Precision Strip AB. Bandställets uppgift är att på ett säkert sätt hålla fast de ihoprullade cylindrarna med bandsstål i en ram som möjliggör transport med gaffeltruck. Konstruktionen är flera decennier gammal har därmed aldrig CE-certifierats. Detta kan innebära att konstruktionen inte uppfyller alla säkerhetskrav. Konstruktionens metod att låsa fast stålbanden kan upplevas icke ergonomisk och håller inte alla band på ett homogent sätt. Låsningen medför dessutom alltid ett glapp då den endast kan justeras stegvis. Projektets mål är att generera och designa en idé på en nykonstruktion av bandställen som moderniserar låsningen och ökar fasthållningsförmågan av bandsstålen. Säkerheten och ergonomin är de viktigaste aspekterna inom projektet. Nykonstruktionen ska klara av att arbeta parallellt med dagens bandställ för att möjliggöra en implementering av nykonstruktionen under en lång tid. Detta på grund av att det idag finns ca 700st bandställ inom fabriken samt att man ej vill stoppa den värdeskapande produktionen. En förstudie genomförs för att skapa en bild om hur bandställen hanteras idag och hur operatörerna låser fast bandställen. En litteraturstudie inom området säkerhet genomförs. Många säkerhetsaspekter avklaras genom att helt enkelt följa Arbetsmiljöverkets dokument Maskiner 2008:3. Den slutgiltiga produkten blev en konstruktion med skivor emellan varje bandsstål som operatören trycker till rätt position. För att låsa skivorna i en position trycker operatören på en fotpedal som sänker ner skivorna så att de trycker emot en gummiduk och skapar friktion. Gummiduken används dessutom som vilostöd för stålbanden. För att låsa upp konstruktionen trycker operatören ytterligare en gång på pedalen. Detta släpper låsningen likt funktionen av en kulspetspenna. Konstruktionen uppfyller alla krav specificerade i kravspecifikationen och nästan alla önskemål. De högprioriterade önskemålen är uppfyllda. Det läggs märke till att konstruktionen har utvecklingsmöjligheter i from av bland annat dess hävarm för fastlåsning av glidskivor. Kraften som operatören måste trycka emot pedalen är relativt hög och andra alternativ på hävarmar kan studeras. / Strip-carriers are today used to store and transport precision strips at voestalpine Precision Strip AB. The Strip-carriers main task is to in a securely and in a stable manner hold the rolledup cylinders of precision strips securely to a frame which allows for transportation with a forklift. The construction is many decades old and has therefore never been CE-certified. This could mean that the construction does not meet some requirements for safety. The designs method for holding the precisions strips can be described as un-ergonomic and does not hold the strips in a homogeneous way. The method of locking the precision strips can also only be locked gradually which always results in some play in the precision strips. The projects goal is to generate and design an idea for a new construction of the strip-carrier which shall modernise the method of locking and increase the clamping force of the precision strips. Safety and ergonomics are of key aspects in this project. The new design shall be able to operate in parallel with todays strip carrier to enable the possibility of implementing the strip-carriers over a long period of time. The reason being that the factory has about 700 stripcarriers in their factory and to not have to stop the value generating production. A pilot study is performed to understand how the strip carriers are manoeuvred today and how the operator locks the precision strips. A literature study is performed in the field of safety. Many safety aspects can be achieved by simply by following the guidelines of Maskiner 2008:3 by Arbetsmiljöverket. The final design is a construction where plates separate each precision strip. The operator can slide these plates to their desired position. To lock the plates in position the operator steps on a pedal with force which lowers the plates against a rubber mat which creates friction. The rubber mat also is used as rest supports for the precision strips. To unlock the plates and free the precision strips the operator steps on the pedal again. The unlocking works with the same principle as a ball-pen locking mechanism. The final design fulfils all the requirements specified in the requirement specification and almost all the requests. All the highly prioritised requests are fulfilled. It is noticed that the design has potential for continued development. An example is the lever for the locking of the plates. The force needed to operate the locking mechanism through the pedal is relatively high and could be further developed.

Psykosocialt arbetsmiljöarbete : En kvalitativ studie om hur enhetschefer inom socialtjänsten förväntas ta ansvar för att främja en god psykosocial arbetsmiljö. / Psychosocial work environment : A qualitative study on how unit managers in social services are expected to take responsible for promoting a good psychosocial work environment.

Petersson, Elin, Johansson, Ellen January 2017 (has links)
The purpose of this study is to examine and deepen the knowledge of how unit managers are expected to take responsibility for promoting a good work environment by translating the new regulations on organizational and social work environment, in social services in a medium-sized municipality in Southern-Sweden. Method: We have used a qualitative approach as method in this study, with semi-structured interviews as data collection method. To gather empirical material, we chose to interview six unit managers who work in social services. Theory: Our theoretical point have been Implementation theory. We also chose the concepts of learning organizations and competence. Our choice of method and concepts have helped us to examine our-empirical-material. Results: The six different themes, presented in the results of this study, are designed based on the new regulations on organizational and social work environment. The different themes in this study are the following: Competences, goals for the organization and the social work environment, workload, management of working hours, offensive treatment, responsibility and the last theme is competence. Our results indicate that the unit managers are not adequately educated about the new regulations, which in turn leads to the implementation of the regulations as intended. Secondly, our results also show weaknesses in resource allocation.

Integrerad arbetsmiljöplanering

Rasouli, Mohammad January 2017 (has links)
Since the early 1980s, several   research programs initiated in the construction industry with the aim of   achieving a better working environment and more codetermination in the   planning of construction projects. Integrated planning (IP) was a project   carried out in 1985-1988 as a collaboration with Lund University, companies   in the construction industry and the trade unions in the afore-mentioned   area. The integrated planning concept was developed and implemented in the   construction industry in building production. IP is a model for integrating   production planning with systematic work environment planning and integrating   the skills of all participants in building production planning from early   stage to finish. The purpose of this study is to assess the extent to which   the work environment plan is a governing document during the ongoing work   environment planning before and during construction. Work Environment Act   (AML) and its provisions (AFS 1999: 3, AFS 2001: 1 and AFS 2015: 4) are   governing for the planning of the working environment in a construction   project. Based on the provisions, the report's research questions focus on   how and at what stage a work environment plan is established, as well as how   the model integrated planning is used in the ongoing work environment   planning prior to construction start and during the production phase. Of the   companies included in the study, three of them, Skanska, Peab and NCC are   Sweden's largest company and work on a national and international scale. The   third is INAB, a small company that mainly works nationally. The results show   that work environment planning starts at an early stage with preventive   actions and routines during the building construction process and mainly   follow the same concept as the integrated planning model. Integrated work   environment planning (IWEP) is a model for building production planning that   can be used in any projects, whatever, its complexity and size. Tallåsen is a   clear example that shows the work environment plan is a governing document during   the production phase. More attention should be paid to the OSA (AFS 2015:4)   by implementing more practical preventive actio / <p>Betyg 170707, H14.</p>

Sledování forem arsenu v potravinách / Monitoring of arsenic forms in foodstuffs

Harkabusová, Veronika January 2008 (has links)
The diploma thesis is dealing with monitoring of arsenic in foodstuffs. The aim of this thesis is the determination of arsenic in samples of fish and rice and the study of forms, in which arsenic occurs, using speciation analysis. Arsenic is known as a toxic element, but its measure of toxicity depends on the chemical form it occurs in. Arsenic is present in the environment naturally or it gets in the environment by human activities. Complete characterization of arsenic compounds is necessary to understand intake, accumulation, transport, detoxification and activation of this element in the natural environment and living systems. The field of arsenic speciation analysis has grown rapidly in recent years, because determination of the total element content is not sufficient in the case of arsenic. Speciation method was done using separation by high performance liquid chromatography and detection by atomic fluorescence spectrometry with hydride generation. Extractable arsenic was present in the form of nontoxic arsenobetaine in all analysed samples of fish. In samples of rice there was confirmed the presence of toxic inorganic species of arsenic, esspecially As (III), but their concentration was at low level.

Speciační analýza selenu v kvasinkách kultivovaných v médiu s přídavkem selenu / Speciation analysis of selenium in selenized yeast

Motlová, Tereza January 2010 (has links)
The aim of the theses was determination of selenium species in yeast Saccharomyces cerevisiae cultivated in medium with added inorganic form of selenium (Sodium Selenite). Concentrations of Sodium Selenite in cultivation medium were 0,1; 1; 10 and 100 mg.l-1. Cultivation was undertaken in fermenting tub for period of 72 hours. Cultivated yeasts were extracted by use of enzymes and subsequently the species of selenium in particular parts of yeasts were determined. In order to determine selenium species, the method of high-performance liquid chromatography in combination with atomic fluorescent spectrometer and technique of hydride generation was used. Having analysed different fractions of the yeasts Saccharomyces cerevisiae it was ascertained that during cultivation the sorption of selenium occurred in form of Se4+ in cell membranes while in cytoplasm no inorganic forms of selenium were found. Furthermore, it was stated that yeasts Saccharomyces cerevisiae are able to metabolically change inorganic forms of selenium to organic forms (selenomethionine), while these forms are present in cytoplasm and they are likely to be bound to proteinic structures of cell membranes. An increase of concentration of Se4+ in cell membranes could be observed as a result of increasing concentration of Sodium Selenite in cultivation medium. In proteinic structures the concentration of organic selenium forms increased only to concentration 10 mg.l-1 of Sodium Selenite in cultivation medium.
