Forming i barnehagen i lys av Reggio Emilias atelierkultur

Forming (Arts and crafts) and children’s creative action with materials and tools are less in use in the kindergarten than before. Political focus on children’s early learning has led to shifts in kindergartens toward other specific disciplines, and requirements for individual testing also of the smallest children’s competencies within these. Kindergarten teachers, educators, researchers and participants in social debate have pointed out that there are epistemological contradictions in descriptions of kindergarten quality as well as between current kindergarten policy documents and requirements for the kindergartens’ staff. Meanwhile, the content and methods in many kindergartens are inspired by practice and philosophy in the municipal kindergartens in Reggio Emilia, Italy. Correlation between kindergartens’ formingprojects and experiences from Reggio Emilia is actualized in particular through the workshop and the studio’s role in children’s learning processes. One starting point for the thesis’ problem area is a documented need for more knowledge about kindergarten’s educational content. The overarching goal of the thesis is to develop new knowledge about how learning takes place in kindergarten through examining the field of forming in kindergartens inspired by Reggio Emilia’s atelier culture. The thesis is theoretically anchored within pragmatism, and ties kindergarten’s aesthetic operations with materials and tools to socio-cultural perspective, social constructivism and post humanistic theory. The empirical material is obtained through a qualitative study with ethnography as methodological approach. The fieldwork is conducted in kindergarten, with two leading research questions: 1) How is atelierism perceived and unfolded in Norwegian Reggio Emilia-inspired kindergartens, and 2) how is forming perceived and unfolded in Norwegian Reggio Emilia-inspired kindergartens. A comprehensive and multifaceted material is analyzed, and the results are presented in the form of three themes: The physical environment, Relations and actions in interplay, and Expression forms and forms of expression. Each of these topics are supported by examples from kindergartens’ adult voices and the constructed empirical material. Insights into how learning takes place in the kindergarten subject of forming with inspiration from the Reggio Emilia atelier culture is discussed in the tension between educational philosophy, Nordic kindergarten tradition and neoliberal trends that kindergarten teachers must adhere to. Learning potentials in children’s opportunities for action in forming in light of the atelier appears in the results of the empirical study. The educational context described is characterized by experimental and playful actions where children’s sensations, curiosity and resistance are interacting with the identity of materials and tools. The results imply aesthetic, ethical, democratic and ecological reflections, which are also valid on a practical action level. The thesis contributes to description and understanding of kindergarten’ content and young children’s learning, the importance of atelier culture as inspiration for the kindergarten, and the further development of methodology and documentation of knowledge expressions.

Neutralization of the edema-forming, defibrinating and coagulant effects of Bothrops asper venom by extracts of plants used by healers in Colombia

We determined the neutralizing activity of 12 ethanolic extracts of plants against the edema-forming, defibrinating and coagulant effects of Bothrops asper venom in Swiss Webster mice. The material used consisted of the leaves and branches of Bixa orellana (Bixaceae), Ficus nymphaeifolia (Moraceae), Struthanthus orbicularis (Loranthaceae) and Gonzalagunia panamensis (Rubiaceae); the stem barks of Brownea rosademonte (Caesalpiniaceae) and Tabebuia rosea (Bignoniaceae); the whole plant of Pleopeltis percussa (Polypodiaceae) and Trichomanes elegans (Hymenophyllaceae); rhizomes of Renealmia alpinia (Zingiberaceae), Heliconia curtispatha (Heliconiaceae) and Dracontium croatii (Araceae), and the ripe fruit of Citrus limon (Rutaceae). After preincubation of varying amounts of each extract with either 1.0 µg venom for the edema-forming effect or 2.0 µg venom for the defibrinating effect, the mixture was injected subcutaneously (sc) into the right foot pad or intravenously into the tail, respectively, to groups of four mice (18-20 g). All extracts (6.2-200 µg/mouse) partially neutralized the edema-forming activity of venom in a dose-dependent manner (58-76% inhibition), with B. orellana, S. orbicularis, G. panamensis, B. rosademonte, and D. croatii showing the highest effect. Ten extracts (3.9-2000 µg/mouse) also showed 100% neutralizing ability against the defibrinating effect of venom, and nine prolonged the coagulation time induced by the venom. When the extracts were administered either before or after venom injection, the neutralization of the edema-forming effect was lower than 40% for all extracts, and none of them neutralized the defibrinating effect of venom. When they were administered in situ (sc at the same site 5 min after venom injection), the neutralization of edema increased for six extracts, reaching levels up to 64% for C. limon.

Kokutai no hongi och Senjinkun – en analys av handböcker för civila och soldater : shintoismens, buddhismens och konfucianismens roll i Japan under andra världskriget

Under andra världskriget rådde en starkt nationalistisk anda i Japan. Bland det mest centrala var att visa lojalitet och vördnad för den japanska kejsaren och staten. Olika handböcker publicerades för att sprida lärorna om statens ideologi och utveckla andan bland japanska soldater och civila. Principer från olika religiösa traditioner blandades samman och inlemmades i lärorna som ingick i handböckerna. I avhandlingen undersöker jag på vilket sätt religiösa doktriner, mer specifikt shintoistiska, buddhistiska och konfucianska, sammanblandades och syntes i ideologin. Mitt fokus ligger på två skrifter, Kokutai no hongi och Senjinkun, som publicerades i Japan under 1930– och 1940–talen för att utveckla den rätta andan inför kriget. Jag gör en tolkande studie av handböckerna för att få en uppfattning av hur de tre religionerna ingick i lärorna inom ideologin. Jag använder mig här av engelska översättningar av skrifterna och stöder mig på tidigare forskning av dem. Förutom det jämför jag de två handböckerna för att se ifall det finns likheter mellan lärorna i dem. Utgående från min studie konstaterar jag att det finns vissa likheter mellan lärorna i de två skrifterna. De tre religionerna hade en viktig roll inom den rådande ideologin. Shintoismen utgjorde grunden för lärorna och de konfucianska och buddhistiska principerna var strukturerade kring de shintoistiska lärorna. Vilken av religionerna som var viktigare än den andra inom ideologin är svårt att avgöra. Alla religionerna var väsentliga beståndsdelar av ideologin.

Roll-to-roll atomic layer deposition process for flexible electronics applications

Atomic Layer Deposition (ALD) is the technology of choice where very thin and highquality films are required. Its advantage is its ability to deposit dense and pinhole-free coatings in a controllable manner. It has already shown promising results in a range of applications, e.g. diffusion barrier coatings for OLED displays, surface passivation layers for solar panels. Spatial Atomic Layer Deposition (SALD) is a concept that allows a dramatic increase in ALD throughput. During the SALD process, the substrate moves between spatially separated zones filled with the respective precursor gases and reagents in such a manner that the exposure sequence replicates the conventional ALD cycle. The present work describes the development of a high-throughput ALD process. Preliminary process studies were made using an SALD reactor designed especially for this purpose. The basic properties of the ALD process were demonstrated using the wellstudied Al2O3 trimethyl aluminium (TMA)+H2O process. It was shown that the SALD reactor is able to deposit uniform films in true ALD mode. The ALD nature of the process was proven by demonstrating self-limiting behaviour and linear film growth. The process behaviour and properties of synthesized films were in good agreement with previous ALD studies. Issues related to anomalous deposition at low temperatures were addressed as well. The quality of the coatings was demonstrated by applying 20 nm of the Al2O3 on to polymer substrate and measuring its moisture barrier properties. The results of tests confirmed the superior properties of the coatings and their suitability for flexible electronics encapsulation. Successful results led to the development of a pilot scale roll-to-roll coating system. It was demonstrated that the system is able to deposit superior quality films with a water transmission rate of 5x10-6 g/m2day at a web speed of 0.25 m/min. That is equivalent to a production rate of 180 m2/day and can be potentially increased by using wider webs. State-of-art film quality, high production rates and repeatable results make SALD the technology of choice for manufacturing ultra-high barrier coatings for flexible electronics.

Development of modular roll service concepts

The goal of this study was to find and develop new or improved service concepts for rolls in a paper machine and secondary targets were to find out what the KPIs and values of the concepts are. Two methodologies were utilized in researching this problem; firstly sales personnel were interviewed about customer values and KPIs and a questionnaire about service modules were sent out to four BSI (basic sales item) responsible persons. Throughout the research process differences in geographic regions were identified and several customer KPIs and values were discovered. The interviews showed that the main concern for customers is the cost of operations. The goal is to produce the same or in some cases more tons with smaller operating costs. The questionnaire standardized the data about service modules and made it possible to link these values, KPIs and concerns of customers to Valmet’s service offering. Eventually these service modules were used to create a service concepts that offer flexibility, cost savings, safety and peace of mind for the customers. With this new conceptual approach Valmet can more flexibly answer to customer quotations and modify the offering to better generate customer value and customer satisfaction. In addition a new BSI was defined and proposed for pilot projects.

Press forming of paperboard – advancement of converting tools and process control

Press forming is nowadays one of the most common industrial methods in use for producing deeper trays from paperboard. Demands for material properties like recyclability and sustainability have increased also in the packaging industry, but there are still limitations related to the formability of paperboard. A majority of recent studies have focused on material development, but the potential of the package manufacturing process can also be improved by the development of tooling and process control. In this study, advanced converting tools (die cutting tools and the press forming mould) are created for production scale paperboard tray manufacturing. Also monitoring methods that enable the production of paperboard trays with enhanced quality, and can be utilized in process control are developed. The principles for tray blank preparation, including creasing pattern and die cutting tool design are introduced. The mould heating arrangement and determination of mould clearance are investigated to improve the quality of the press formed trays. The effect of the spring back of the tray walls on the tray dimensions can be managed by adjusting the heat-related process parameters and estimating it at the mould design stage. This enables production speed optimization as the process parameters can be adjusted more freely. Real-time monitoring of pressing force by using multiple force sensors embedded in the mould structure can be utilized in the evaluation of material characteristics on a modified production machinery. Comprehensive process control can be achieved with a combination of measurement of the outer dimensions of the trays and pressing force monitoring. The control method enables detection of defects and tracking changes in the material properties. The optimized converting tools provide a basis for effective operation of the control system.

Factors Affecting Runnability of Press Forming Equipment

The growth of the food packaging industry has raised more interest in bio-based fibre packing. The use of petroleum based packages is unfriendly to the environment while bio-based is a sustainable option for food packing. In this Master Thesis the aim was to discover how the press forming machineries runnability is affected by parameters of the press and how it also affects formability of paperboard trays. Familiarisation of the working operation parameters was done with the KAMA ST 75 flat-bed die cutting machine and the VP3-70 mould press. Some small test runs of moulding trays where done to get acquainted to the adjustment parameters of the machines. Literature study was done on how paperboards physical properties react to the forces applied during press forming. The study of what kind of defects to the paperboard tray might occur during forming process and the causes for these defects. Also how the parameters of the press forming machine affects formability of the tray. Maintenance procedures was done to the press forming machine to enhance the reliably of production process. Tool alignment measurement was done to determine proper alignment. Laboratory test of the physical properties of the test material was done to find any connection to how the test material performs in press forming. An evaluation criterion was made to evaluate the dimensions and defects of the tray. From the test result a conclusion can be drawn on how the parameters of the press forming process affect the paperboard material. Based on the results the adjustment the parameters of moulding machines to the mechanical properties of paperboard it is possible to produce high quality fibre passed trays for the food packaging industry.

Investigations into the determinations of hydride-forming elements

Analytical methods for the determination of trace amounts of germanium, tin and arsenic were established using hydride generation coupled with direct current plasma atomic emission spectrometry. A continuous gas flowing batch system for the hydride generation was investigated and was applied to the determination of germanium(Ge), tin(Sn), antimony(Sb) and lead(Pb) (Preliminary results suggest that it is also applicable to arsenic)As) ). With this system, the reproducibility of signals was improved and the determination was speeded up, compared with the conventional batch type hydride generation system. Each determination was complete within one minute. Interferences from a number of transition metal ions, especially from Pd(II), Pt(IV), Ni(II), Cu(II), Co(II), and Fe(II, III), have proven to be very serious under normal conditions, in the determination of germanium, tin, and arsenic. These interference effects were eliminated or significantly reduced in the presence of L-cystine or L-cysteine. Thus, a 10-1000 fold excess of Ni(II), Cu(II), Co(II), Fe(II), Pt(IV), Pd(II), etc. can be tolerated without interference, In the presence of L-cystine or L-cysteine, compared with absence of interference reducing agent. The methods for the determination of Ge, Sn, and As were examined by the analyses of standard reference materials. Interference effects from the sample matrix, for example, in transition metal-rich samples, copper, iron and steel, were eliminated by L-cystine (for As and Sn) and by LI cysteine (for Ge). The analysis of a number of standard reference materials gave excellent results of As and Sn contents in agreement with the certified values, showing there was no systematic interference. The detection limits for both germanium and tin were 20 pg ml- I . Preliminary studies were carried out for the determination of antimony and lead. Antimony was found to react with NaBH4, remaInIng from the previous determinations, giving an analytical signal. A reversed injection manner, i.e., injection of the NaBH4 solution prior to the analyte solution was used to avoid uncertainty caused by residual NaBH4 present and to ensure that an excess of NaB H4 was available. A solution of 0.4% L-cysteine was found to reduce the interference from selected transition metal ions, Co(II), Cu(II), Ni(II) and Pt(IV). Hydrochloric acid - hydrogen peroxide, nitric acid - ammonium persulphate, and potassium dichromate malic acid reaction systems for lead hydride generation were compared. The potassium dichromate - malic acid reaction medium proved to be the best with respect to reproducibility and minimal interference. Cu(II), Ni(II), and Fe(II) caused strong interference In lead determinations, which was not reduced by L-cysteine or Lcystine. Sodium citrate, ascorbic acid, dithizone, thiosemicarbazide and penicillamine reduced interferences to some extent. Further interference reduction studies were carried out uSIng a number of amino acids, glycine, alanine, valine, leucine and histidine, as possible interference reducing agents in the determination of germanium. From glycine, alanine, valine to leucine, the interference reduction effect in germanium determinations decreased. Histidine II was found to be very promising In the reduction of interference. In fact, histidine proved more efficient than L-cystine and L-cysteine In the reduction of interference from Ni(II) in the determination of germanium. Signal enhancement by easily ionized elements (EIEs), usually regarded as an interference effect in analysis by DCP-AES, was studied and successfully applied to advantage in improving the sensitivity and detection limit in the determination of As, Ge, Sn, Sb, and Pb. The effect of alkali and alkaline-earth elements on the determination of the above five hydride forming elements was studied. With the appropriate EIE, a signal enhancement of 40-115% was achieved. Linear calibration and good reproducibility were also obtained in the presence of EIEs. III

The versatility and utilization of phosphorus based compounds in classic carbon-carbon bond forming and esterification reactions

The phosphonium salt room temperature ionic liquid tetradecyltrihexylphosphonium chloride (THPC) has been employed as an efficient reusable media for the palladium catalyzed Suzuki cross-coupling reaction of aryl halides, including aryl chlorides, under mild conditions. The cross-coupling reactions were found to proceed in THPC containing small amounts ofwater and toluene (single phase) using potassium phosphate and 1% Pd2(dba)3'CHCI3. Variously substituted iodobenzenes, including electron rich derivatives, reacted efficiently in THPC with a variety of arylboronic acids and were all complete within 1 hour at 50°C. The corresponding aryl bromides also reacted under these conditions with the addition of a catalytic amount of triphenylphosphine that allowed for complete conversion and high isolated yields. The reactions involving aryl chlorides were considerably slower, although the addition of triphenylphosphine and heating at 70°C allowed high conversion of electron deficient derivatives. Addition of water and hexane to the reaction products results in a triphasic system, from which the catalyst was then recycled by removing the top (hexanes) and bottom (aqueous) layers and adding the reagents to the ionic liquid which was heated again at 50°C; resulting in complete turnover of iodobenzene. Repetition of this procedure gave the biphenyl product in 82-97% yield (repeated five times) for both the initial and recycled reaction sequences. IL ESTERIFICATIONREACTION A new class oftrialkylphosphorane has been prepared through reaction of a trialkylphosphine with 2-chlorodimethylmalonate in the presence oftriethylamine. These new reagents promote the condensation reaction of carboxylic acids with alcohols to provide esters along with trialkylphosphine oxide and dimethylmalonate. The condensation reaction of chiral secondary alcohols can be controlled to give either high levels of inversion or retention through a subtle interplay involving basicity of the reaction media, solvent, and tuning the electronic and steric nature of the carboxylic acid and stenc nature of the phosphorane employed. A coherent mechanism is postulated to explain these observations involving reaction via an initial acyloxyphosphonium ion.
