Hvordan øve hellige handlinger? : en profesjonsdidaktisk studie av øving av muntlige ferdigheter innenfor en norsk presteutdanning

How can the holy craft of liturgy be trained? A study of approaches to instruction in training oral skills within education of the Norwegian clergy The theme of this study is the competence of expression of clerics performing liturgies as part of their duties in the Norwegian Lutheran Church. The aim of the study is to find a teaching practice which can raise the competence in oral expression characteristic of the clergy profession. The teaching practice is explored and discussed within the context of the basic education of the clergy. The main thesis is formulated as a question: How can the holy craft of liturgy be trained? An underpinning of the study is that liturgical acts are holy, which gives these performances an aspect of otherness. This otherness constitutes a clear agreement between the students and the teacher, and between the professional and the employer. The pre-understanding of the researcher is that these liturgical oral acts are trainable, and that there is a need and a necessity to train in these skills. Three research questions are elaborated on in the explorative section of the study: • What is characteristic of a competence of expression connected to the profession? • How can this competence of expression connected to liturgical performance be developed? • What is the importance of this competence in the holy craft of liturgy for the development of a cohesive professional self-understanding? The study is based on a research and development project where the researcher as the teacher and students from one specific clergy education in Norway (MF) were the source of the empirical material. The empirical data came from practice with two external observers› logs on the coaching, video observations, of the teacher and the students› texts on the practice under study, which is liturgical performance. The researcher›s log and field notes also provide material for the analysis. This is a qualitative project and an arts education project carried out within an interpretative framework. The theoretical framework has three perspectives: a structural approach based on the system theory of Niklas Luhmann, an epistemological approach discussing forms of knowledge in practice or informing practice and an arts education approach. The results indicate that the competence in oral liturgical performance can be considered a trainable skill, and that this training can be understood as an arts education method of instruction based on meaningful communication, dramaturgical thinking and the development of authenticity. The main result from this study can be considered as articulating and sketching the contours of the field of knowledge where the students embody the meaning of the clergy profession ‒ and this articulation has an innovative potential as knowledge combining experience and theoretical understanding.

Lyssnande : en vårdvetenskaplig betraktelse

Denna vårdvetenskapliga studie har sökarljuset riktat mot lyssnande som något fundamentalt för människan. Studiens syfte är att utifrån forskarens traditionstillhörighet och en klart uttalad teorikärna, värdegrund, ontologisk grund samt en hermeneutisk ansats avtäcka nytt inseende om vad lyssnande är samt vad som är vårdande i lyssnande. Studiens avsikt är att bringa ontologisk klarhet, klargöra lyssnandets plats inom vårdvetenskaplig teoribildning samt bidra med bilder av det vårdande med relevans för klinisk praxis. Det hermeneutiska arbetssättet är en ständig rörelse mellan det enskilda och gemensamma. Den vårdvetenskapliga traditionens grundläggande ordning utgör siktet för kunskapssökandet samtidigt som det är gentemot den caritativa vårdteorin som nytt inseende ur historiska källor reflekteras för att lysa upp och synliggöra det evidenta och ursprungliga om lyssnande. Begreppsutredningen av lyssna som begrepp ger förståelse för begreppets historiska ursprung och dess starka band med begreppen lyss, lystra, lyda, följa, iaktta, se samt lust, begär, böjelse och glädje. Läsning och begrundan av filosoferna Bubers, Lévinas och författaren Dostojevskijs livsverk avtäcker vittnesbörd och stillbilder som tolkas för att synliggöra tolkningsantaganden om lyssnandets väsen och gestaltning. Jag har läst och begrundat texterna med öppenhet, lyhördhet och en kvardröjande hållning för att låta dem beröra, tilltala mig och framträda som något nytt. Ur de enskilda texterna avtäcks mönster av en gemensam inre ordning och en gemensam stillbild och tolkningsantaganden om lyssnande formas. När den gemensamma inre ordningen får sammanstråla med studiens vårdvetenskapliga grund synliggörs en urbild och teser om lyssnande samt det vårdande i lyssnande. Avtäckandet visar att lyssnande är en grundhållning till livet självt. Människan lyssnar till sitt innersta väsen för att tillägna sig en inre grundordning samt hörsamma sin tillhörighet i en mera allomfattande gemenskap till den skapande, den andre och det oändliga. I ljuset av kärlekens kraft och bejakandet av mänskligt lidande kan ensamhet och gemenskap sluta förbund med varandra i en mellanverklighet som bär oändlighetens och evighetens kännetecken, och som får toner av det heliga och eviga att ljuda i allt och alla i en närvaro här och nu. Lyssnande är en väsenshandling som uttalas genom en vårdande hållning att tjäna, offra och bära ansvar för den andre med medmänsklig barmhärtighet och medmänskligt medlidande. Band till den andre knyts genom den egna sårbarheten och genom att med ödmjukhet, äkthet och gästfrihet bjuda in och välkomna den andre i sin annanhet. Den vårdande gemenskapen skapar en rörelse som bär på en livsbringande kraft genom vilken människan uppnår frihet att varda, finna näring och försoning.

Germination of Caesalpinia leiostachya (benth.) ducke seeds classified by size and shape

Caesalpinia leiostachya (Benth.) Ducke (Caesalpiniaceae) is a Brazilian legumenous tree whose seeds present different sizes and shapes, with dormancy imposed by a waterproof coat. In order to improve that quality of lot, seeds were classified by width in sieves of circular meshes (13, 14, 15, 16 and 17) and manually separated by shape in elongate, round and angular. Masses of 1000 seeds were determined and the thickness of each width and shape seedclass was measured, and coat permeability of the seeds classified by the width was investigated. Seeds were scarified in concentrated sulphuric acid and submitted to the germination test. Both final percentage and speed of germination index were evaluated. The classification of the seeds improved the quality of the lot, and the coat permeability was not affected by seed width. Elongated-flat seeds are of low physiological quality and should be discarded. Masses of 1000 seeds, percentage final and speed of germination increased with the width of the seeds. Both elongated and angular seeds had similar germinative behavior, and round seeds are of greater thickness and of superior physiological quality.

Benefits of automated acclimatization during the pre-milking phase of lactating girolando cows

The aim of this paper was to evaluate the automated acclimatization effects during pre-milking of cows on thermal conditioning, physiology, milk production and cost-benefit of the automated adiabatic evaporative cooling system (AECS). The treatments 20; 30; 40 min and control consisted of exposure time of pre-milking cows to the automated AECS. Sixteen cows were used with an average daily milk yield of 19 kg, distributed in a 4 x 4 Latin square design. The Tukey's test (P<0.05) was used to compare the means. The environmental variables, dry bulb temperature (DBT, ºC) and relative humidity (RH, %), were recorded every minute, which allowed the determination of the system efficiency through the Temperature and Humidity Index (THI). The respiratory rate (RR), rectal temperature (RT) and temperature of the coat (TC) were measured before and after the acclimatization. The 40 min treatment kept the environmental variables and the comfort indexes within recommended limits. The physiological variables (RR, RT and TC) were lower in the 40 min treatment and reflected positively on milk production, which increased 3.66% compared to the control treatment. The system was profitable, having a 43 days return on investment and a monthly revenue increase of R$ 1,992.67.

Biopohjaiset polymeerit dispersiopäällystyksessä

Työn aiheena oli tehdä muotoiltavissa oleva rasvankestävä pakkauskartonki. Polymeeridispersiopäällystettyjä pakkauskartonkeja käytetään kertakäyttöisissä tuotteissa kuten vuoissa, kupeissa ja lautasissa. Tuotteiden on kestettävä rasvaa niiden lopputarkoituksen mukaisesti. Pakkausala jatkaa vuosittaista kasvuaan vauhdilla. Uusia kierrätettäviä biopohjaisia ja luonnolle ystävällisempiä pakkaustuotteita on kehitettävä kasvun tyydyttämiseksi. Biopohjaiset pakkaustuotteet ovat mahdollisia ratkaisuja ympäristöön kohdistuvien ongelmien vähentämiseksi ja öljypohjaisten raaka-aineiden korvaajiksi. Diplomityön teoriaosuudessa keskityttiin dispersiopäällystyksessä käytettyihin biopolymeereihin ja niiden toimivuuteen suojaavina kalvoina. Teoriaosuudessa käsiteltiin myös rasvankestoa ja rasvankestävien tuotteiden materiaaliominaisuuksia. Kirjallisuuden perusteella havaittiin luonnonpolymeerien alhaisen kuiva-ainepitoisuuden ja korkean päällystemäärätarpeen muodostamat haasteet dispersiopäällystyksessä. Pohjakartongin karheudella ja tiiveydellä sekä suojaavan polymeerin kalvon rakenteella huomattiin olevan suuri merkitys rasvankeston saavuttamiseksi. Kokeellinen osa jakautui kolmeen osakokonaisuuteen: laboratoriokokeisiin, esipilotointiin ja varsinaiseen pilot-koeajoon. Esikokeiden perusteella suojaavat kalvot, joiden raaka-aineena käytettiin biopohjaisia dispersiopolymeerejä, antoivat riittäviä rasvankesto-ominaisuuksia, mutta eivät kestäneet konvertointia. Pienellä synteettisten polymeerien lisäyksellä pystyttiin parantamaan päällystettyjen kartonkien rasvankestoa sekä konvertoitavuutta. Pilot-koeajonäytteiden testaustulokset tukivat esikokeissa tehtyjä havaintoja. Tämän työn perusteella kohtuullinen lisäysmäärä synteettistä polymeeriä voi parantaa merkittävästi biopohjaisen suojaavan kalvon antamaa rasvankestoa sekä päällystetyn kartongin konvertoitavuutta.

Comparison of two commercial kits and two extraction methods for fecal glucocorticoid analysis in ocelots (Leopardus pardalis) submitted to ACTH challenge

The ocelot (Leopardus pardalis) is included in list of wild felid species protected by CITES and is part of conservation strategies that necessarily involve the use of assisted reproduction techniques, which requires practical and minimally invasive techniques of high reproducibility that permit the study of animal reproductive physiology. The objective of this study was to compare and validate two commercial assays: ImmuChem Double Antibody Corticosterone 125I RIA from ICN Biomedicals, Costa Mesa, CA, USA; and Coat-a-Count Cortisol 125I RIA from DPC, Los Angeles, CA, USA, for assessment of fecal glucocorticoid metabolites in ocelots submitted to ACTH (adrenocorticotropic hormone) challenge. Fecal samples were collected from five ocelots kept at the Brazilian Center of Neotropical Felines, Associação Mata Ciliar, São Paulo, Brazil, and one of the animals was chosen as a negative control. The experiment was conducted over a period of 9 days. On day 0, a total dose of 100 IU ACTH was administered intramuscularly. Immediately after collection the samples were stored at 20C in labeled plastic bags. The hormone metabolites were subsequently extracted and assayed using the two commercial kits. Previously it was performed a trial with the DPC kit to check the best extraction method for hormones metabolites. Data were analyzed with the SAS program for Windows V8 and reported as means ± SEM. The Schwarzenberger extraction method was slightly better when compared with the Wasser extraction method (103,334.56 ± 19,010.37ng/g of wet feces and 59,223.61 ± 12,725.36ng/g of wet feces respectively; P=0,0657). The ICN kit detected an increase in glucocorticoid metabolite concentrations in a more reliable manner. Metabolite concentrations (ng/g wet feces) on day 0 and day 1 were 66,956.28 ± 36,786.93 and 92,991.19 ± 28,555.63 for the DPC kit, and 205,483.32 ± 83,811.32 and 814,578.75 ± 292,150.47 for the ICN kit, respectively. The limit of detection for the ICN kit was 7.7 ng/mL for 100% B/Bo (25ng/mL for 88%B/Bo) and for the DPC kit it was 0.2ug/dL for 90.95% B/Bo (1ug/dL for 81.27% B/Bo). In conclusion it was confirmed that the Schwarzenberger extraction method and the ICN kit are superior for extracting and measuring fecal glucocorticoid metabolites in ocelot fecal samples.

Ultrastructural characterization of bovine umbilical cord blood cells

The umbilical cord blood (UCB) is an important source of pluripotent stem cells, which motivated researches on ontogeny and transplantation. The morphological characterization of umbilical cord cells is the first step to establish subsequent experiments on these areas. Although some information on humans can be found, no data on UCB is available for bovines. Therefore, this work is the first attempt to conduct an ultrastructural characterization of bovine umbilical cord blood. Blood was collected from the umbilical cord of twenty fetuses by punction of the umbilical vein. Samples were processed for whole leucocytes observation by centrifugation and the buffy coat was collected. Cells were washed and pelleted and prepared according to the standard protocol of the transmission electron microscopy. The presence of cells with morphologic characteristics compatible with the precursors from the erythrocytic, neutrophilic, eosinophilic, basophilic, and lymphocytic lineages was observed. Atypical cells with peculiar morphological features, strongly similar to apoptotic cells, were seen. Bovine neutrophils with three types of cytoplasmic granules were also found in the blood. The ultrastructural characteristics of observed bovine UCB cells where similar to those found in other species, suggesting that bovines could possibly constitute an experimental model for approaches on UCB cells research.

Mikrohuokoisen pinnoitteen kehittäminen suodatinkankaan päälle

Mikrohuokoisia membraaneja käytetään monissa suodatussovelluksissa kuten vedenpuhdistuksessa. Tämän työn tavoite oli pinnoittaa suodatinkankaita mikrohuokoisella membraanilla. Membraanimateriaalin ja suodatuskankaan yhdistelmällä tavoiteltiin komposiittimateriaalia, jolla on membraanin selektiivinen erotuskyky ja kankaan mekaaniset ominaisuudet. Tämän työn kirjallisuusosa käsittelee membraanin valmistusta faasi-inversiomenetelmällä, pinnoitteeksi soveltuvia membraanimateriaaleja sekä pinnoitteen lujittamista. Kokeellisessa osassa suodatuskankaalle kehitettiin sopivaa pinnoitusmenetelmää. Pinnoitemateriaaleina käytettiin akryylidispersioainetta, polyamidia ja polysulfonia. Tuloksista huomattiin, ettei akryylidispersioaine soveltunut pinnoitemateriaaliksi. Kangasta onnistuttiin pinnoittamaan polyamidilla ja pinnoitusolosuhteita kontrolloimalla saatiin aikaiseksi pinnoite, joka pysyi kankaassa kiinni ja jonka rakenne koostui noin 12 μm huokosista. Polymeeriliuoksen pitoisuuden huomattiin vaikuttavan pinnoitteen rakenteeseen, mutta siihen jäi edelleen suuria avoimia huokosia. Suuret yksittäiset huokoset laskivat kuplapistepainetta ja tekivät huokoskokojakaumasta leveämmän. Polyamidipitoisuudella 14 ja 16 m–% pinnoite oli tunkeutunut kankaan sisään ja sen rakenne oli huokoinen, mutta pintakerrokseen muodostunut tiivis ihokerros tukki materiaalia. Tulosten perusteella kankaiden pinnoittaminen membraanikerroksella on mahdollista mutta pinnoitusprosessia täytyy edelleen kehittää, jotta päästään pienempään huokoskokoon ja kapeampaan huokoskokojakaumaan pinnoitteessa.

Blade and rod coating of low solid dispersions

Työn aiheena oli tehdä ohut barrierkalvo terä- tai sauvapäällystys menetelmällä. Erilaisissa elintarvikepakkauksissa käytetään hyviä barrier-ominaisuuksia omaavia ohuita päällysteitä. Elintarvikepakkauksen tehtävä on suojata pakattua tuotetta ympäristöltä, mahdollistaa helppo kuljetus ja säilytys sekä antaa tarvittavat tiedot tuotteesta tuotteen käsittelijöille ja loppukäyttäjille. Diplomityön teoriaosuudessa keskityttiin barrierpäällystykseen, eri päällystysmenetelmiin, niiden erityisvaatimuksiin ja ominaisuuksiin. Teoriaosuudessa käsiteltiin myös vaadittavia barrier-ominaisuuksia ja haasteita niiden saavuttamisessa. Kirjallisuuden perusteella haasteiksi nousivat helposti muodostuvat mikroreiät. Kokeellinen osa jakautui kahteen osakokonaisuuteen: laboratoriokokeisiin ja pilot-koeajoon. Laboratoriokokeita tehtiin ennen pilot-ajoa, jotta pilot-koeajoon voitiin valita parhaat päällystereseptit. Pilot-koeajonäytteiden päällystemäärät osoittautuivat liian pieniksi ja siksi laboratoriossa tehtiin jatkotutkimuksia riittävän päällystemäärän saavuttamiseksi. Tämän työnperusteella pohjakartongin ominaisuuksilla, erityisesti karheudella, on merkittävä vaikutus päällystyksen onnistumisessa ja yksinkertaisilla resepteillä ja päällystysmenetelmillä ei saada tarpeeksi laadukasta kalvoa.

Density and sowing season of two Brachiaria species on the soybean culture

The aim of this study was to evaluate the growth and yield of soybean cultivar M-8766 in consortium with Brachiaria brizantha. BRS Piata and Brachiaria ruziziensis at different densities and sowing dates. The experimental design was randomized blocks with treatments arranged in a factorial 2 x 2 x 3 with four replications. Used as factors grass species (Brachiaria brizantha Piata and Brachiaria ruziziensis BRS) intercropped with soybean M-8766, sowing dates (12 and 24 days after soybean emergence) and three seeding rates (0, 5, 10 kg ha-1 of seed). At 71 days after soybean emergence were evaluated plant height, stem diameter, dry mass of leaves, stems and shoots, and 4 months after sowing determined the weight of 100 grains and soybean yield. The results showed that when seeded at a density of 10 kg ha-1 at 12 and 24 DAE soy, Brachiaria brizantha. BRS Piata caused reduction in yield in the order of 6.71% and 3.03% respectively, while the Brachiaria ruziziensis was one that caused a greater reduction in productivity in the order of 13.42 and 16.23%, respectively, of these values expression when considering the price of soybean sack. B. ruziziensis expressed less competitive with soybean. However, the large biomass production of this grass provides deployment system till the next harvest.

SEED DORMANCY BREAKING TREATMENTS FORAFRICAN PURSLANE (Zaleya pentandra)

ABSTRACT Understanding the mechanisms involved in releasing seed dormancy is crucial for effective plant management and renewal of species in the arid zone. Zaleya pentandra is an emerging invasive weed of the arid areas of Pakistan. We investigated the effects of different dormancy breaking treatments on the germination of Z. pentandra seeds. Seeds were treated with hot water (by placing them in boiling water for 5, 15, 30, 60, 90, 120, and 150 min), dry heat (by placing them in a preheated oven at 70 oC for 1, 2, and 4 hours; at 70 oC for 1, 2, 3, and 4 days, and at 200 oC for 5, 10, 15, 30, and 45 min) and stratification (by placing them at 2-5 ºC in a refrigerator for 5, 10, 30, and 60 min; for 3, 6, and 12 hours, and for 1, 2, 4, 8, 15, and 30 days). Seeds also were soaked in thiourea ([(NH2)2CS] (0, 2,500, 5,000, 7,500, and 10,000 mg L-1 for 24 h at 30 oC) and in KNO3 (0, 10,000, 20,000, 30,000, 40,000, 50,000, and 60,000 mg L-1 for 24 h at 30 oC). Additionally, seeds were scarified with HCl (for 3, 6, 9, 12, 15, 18, and 21 h), HNO3 (for 3, 6, 9, 12, 15, 18, and 21 h), and H2SO4 (for 20, 40, 60, 80, 100, and 120 min at 30 oC) and also mechanically scarified with sandpaper. Zaleya pentandra seeds showed typical signs of hard seed coat dormancy. Mechanical scarification and acid treatments promoted seed germination to a varying degree. Seed scarification with HNO3 for 12 to 18 h as well as with HCl for 12 h and 15 h was efficient in breaking dormancy of Z. pentandra seeds, providing germination up to 92.5%. Seed scarification with H2SO4 from 20 to 120 min showed little effect, whereas hot water, dry heat, stratification and various concentrations of thiourea and KNO3 were ineffective in breaking Z. pentandra seed dormancy.

Estrutura do tegumento seminal de quatro espécies de Leguminosae (Caesalpinioideae), ocorrentes numa área de caatinga (PE ­ Brasil)

Neste estudo observou-se que os tegumentos seminais de Caesalpinia ferrea, C. pyramidalis, Senna martiana e S. spectabilis var. excelsa estão compostos de um estrato de macrosclereídes, revestido por cutícula e subcutícula, seguido por uma camada de osteosclereídes, parênquima esclerificado e camada interna também de osteosclereídes. A impermeabilidade dos tegumentos seminais, possivelmente, se restringe à região das macroesclereídes.

Possibility to add a barrier layer to a fibre tray package in the moulding stage

The main objective of the present study was to analyze the best approach on how to coat paperboard trays at the pressing stage. The coating gives the paperboard enhanced barrier and mechanical properties. The whole process chain of the barrier coating development was studied in the research. The methodology applied includes obtaining the optimum temperature at which good adhesion and bonding is formed between paperboard and skin film. Evaluation of mechanical properties after the coatings; such as cracking, curling and barrier properties was performed.

Morphology and anatomy of the developing fruit of Maclura tinctoria, Moraceae

(Morphology and anatomy of the developing fruit of Maclura tinctoria, Moraceae). Maclura tinctoria (L.) D. Don ex Steudel was selected for the present study due of its economic and medicinal importance. The purpose of this investigation is to present a detailed description of the fruit development, specially by: (a) defining the fruit type presented by the species, and (b) characterizing the seed type of the species based upon the presence or not of mechanical tissue on the seed-coat. The fruit originates from the subglobose female inflorescence which consists of small unipistillate flowers with superior ovary, unilocular and uniovular apical placentation. The mature fruit is multiple, constituted of small drupes. The ovule is ana-campylotropous, suspended, bitegmic and crassinucellate. The mature seed is flattened, slightly ovated, cream colored, with unspecialized membrane coat with thin-walled cells more or less crushed. The seed has parenchymatic endosperm with lipophilic content. The embryo is straight, with two cotyledons of the same size. Ontogenetic studies reveal that the fruits are infrutescences. The fleshy edible part is derived from the perigone and inflorescence axis. The drupes consist of a single pyrene of macrosclereids.

Viability and vigor of jamun (Syzygium cumini) seeds

Jamun (Syzygium cumini L. Skeels) (Black plum, Damson plum) fruits weigh between 2-5 g at maturity. Fresh seeds represented 20-80% of the total fruit weight; the seed coat and cotyledons contributed 6% and 94% to the total seed weight respectively, while the weight of the embryonic axis was insignificant. Only the embryonic axis stained with Tetrazolium, not the cotyledons. The seeds are polyembryonic with up to four embryos, of which at most three germinate. Decoated seeds germinated faster than coated seeds under nursery conditions, with high significant germination percentages, dry matter production rates and vigor indices. The lack of staining of the cotyledon by tetrazolium was probably due to the presence of an impermeable layer. Decoating seeds for faster germination is recommended.
