Analiza naprezanja i deformacija u toplinski opterećenoj štapnoj konstrukciji

U ovom radu analizirana je toplinski opterećena konstrukcija. Uslijed toplinskog opterećenja javljaju se deformacije, naprezanja te pomaci promatrane konstrukcije. Varijacijom vrste opterećenja konstrukcije mijenjaju se raspodjele temperatura, deformacija, naprezanja te pomaka. Provedene toplinske analize verificirane su analitičkim putem te uspoređene s rezultatima dobivenima pomoću programskog paketa Abaqus. Provedene verifikacije su sljedeće: promjena temperaturnog polja, raspodjela temperature uslijed prijenosa topline konvekcijom te temperaturna raspodjela u elementu uslijed konduktivnog provođenja topline. U promjeni temperaturnog polja promatra se utjecaj jednolike promjene temperature cijelog štapa. U raspodjeli temperature uslijed konvekcije uz određene rubne uvjete posebno je dodana konvekcija po čvorovima štapa. Stoga se uz provođenje topline također javljaju i gubici konvektivnog prijelaza topline. U temperaturnoj raspodjeli u elementu uslijed provođenja topline kroz krutinu tj. kondukciji promatra se pad temperature. U konačnici, nakon verifikacije provedena je mehanička analiza konstrukcije sa spomenutim verificiranim toplinskim opterećenjima

Isolation and Identification of Hsc70 Conjugates in RAW264.7 Murine Macrophage-Like Cells

IL12R- β2 is a Type I cytokine receptor and contains the WXXW (WSNWS) sequence that often predicates the post-translational addition of mannose to a tryptophan residue via a carbon-carbon bond. This study will stimulate expression of IL12R- β2 in RAW 264.7 Macrophage-Like Cells by shutting down the extracellular signal kinase (ERK) pathway and introducing inflammatory agents lipopolysaccharide and CpG DNA in order to collect a concentrated sample of IL12R- β2. These samples will be analyzed for the presence of C-mannosyltryptophan residu

School Principals’ Sources of Knowledge

The purpose of this study was to determine what sources of professional knowledge are available to principals in 1 rural East Tennessee school district. Qualitative research methods were applied to gain an understanding of what sources of knowledge are used by school principals in 1 rural East Tennessee school district and the barriers they face to using knowledge sources. This study questioned whether these resources are adequate for, accessible to, and used by school principals. In this study I examined principals’ perceptions of the need for a district-led mentoring program. The study first consisted of a preliminary data collection procedure. Ten of the school district’s principals completed a demographic questionnaire and list of survey questions developed from the 4 research questions and elements of the literature review. These data were reviewed by the researcher in order to categorize the respondents’ responses into meaningful demographic data. The final data collection procedure involved 6 principals chosen to complete face-to-face interviews consisting of open-ended questions developed from an initial interview protocol. Results indicated the principals’ examples of seeking knowledge and information from data sources, collegial professionalism, readings of research and literature, and professional development. The principals presented evidence that they embrace teaching and learning within their roles as school principals. The 2 areas on which the principals focused their concerns were time and the current state department educational reforms. The principals provided recommendations for a future district-wide principal mentoring program
