Der volle Inhalt der QuelleThe aim of this report is to investigate whether there is one method for cleaning of shellac coated surfaces which could replace the other methods usually used in restorers/conservators workshops, a method which reaches up to a set of formulated standards concerning safety, efficiency and simplicity. Frequent use of organic solvents and materials with unknown, uninvestigated content constitutes a potential risk in a long term perspective, both for the worker and the object. If it is possible to replace these methods with one that is scientifically investigated, this must be seen as a better alternative. The range of different cleaning material has been looked into and from the set of standards one non-ionic tenside has been picked out for further investigation. Theoretically, non-ionic tensides is to be considered as more suitable for cleaning of shellac surfaces since they interact with the surface in a less harmful way than ionic tensides. From cleaning analysis it has shown that the non-ionic tenside Tinovetin® JUN gives pleasing cleaning results equivalent to the ordinary washing up liquid, “Fairy” (in Sweden known as “Yes”). However, from wetting ability analysis it shows that “Fairy” is more powerful. A contact angle analysis showed that Tinovetin® JUN leaves more residue than “Fairy” but the difference is not remarkable. Since washing up liquid contain ionic tensides, it is motivated to advocate Tinovetin® JUN preferably to “Fairy”.

Der volle Inhalt der QuelleDenne rapport er et studie i ældre spritpoliturer. Spritpoliturer påføres med polerelap og kan sammenlignes med den teknik som vi populært i dag kender som metoden for fransk polering eller håndpolering.Rapporten fordyber sig i emnet omkring spritpoliturer og ender op omkring et praktisk eksperiment om udvalgte politurer. Ældre snedkerkunst kendetegnes ved, at det kan studeres ned til mindste detalje. Overfladebehandlingerne var så absolut ingen undtagelse og især ikke politurbehandlingerne, hvor de ofte eksotiske harpikser af forskellige art blev blandet med største omhu og forståelse for detaljer for at opnå præcis den finish, der skulle tjene formålet bedst. Blandinger af harpiks og sprit dannede forskellige politurer til fernis for stole, instrumenter, toiletmøbler, paneler etc.
Således skal rapporten fungere som en historisk gennemgang af et udvalg af spritpoliturer fra første halvdel af 1800- tallet. Forud for rapportens praktiske eksperiment hvor der poleres med udvalgte spritpoliturer følges der op på de håndværksteknikker og den viden, der har ligget til grund for poleringen.
This degree project is a study on traditional ethanol-based polishes. Ethanol-based polishes are applied with a pad and can be compared with the method today known as French Polishing or Hand Polishing. The report enter deeply into the subject and ends up with applied experiments with some selected polishes. The art of cabinetmaking can be studied down to minute detail. Polishes were no exception, especially not ethanol-based polishes, where most often exotic resins of different origin were mixed with great care and understanding in order to attain the most appropriate finish for every single piece. By mixing resins and ethanol different polishes were obtained for chairs, instruments, dressing furniture, panels etc.The report is meant to serve as historic review of some selected polishes from the first half of the 19th century. Before the practical polishing experiments is included information on handicraft techniques and background knowledge necessary for the actual polishing procedure.

Der volle Inhalt der QuelleThe aim of this work was to evaluate in vitro and in vivo the properties of a new natural resin-based fluoride varnish, Shellac F (Hoang-Tu Hung et al. Faculty of Odonto-Stomatologie - University of Medicine and Pharmacy, Ho Chi Minh city - Viet Nam). The results lead to the following conclusions : 1. Shellac F is not toxic for the pulp and the periodontium. 2. Shellac F decreases dentin permeability by obliterating the dentina canalicular openings. 3. Shellac F is effective as a desensitizing agent. 4. Shellac F has caries-preventive efficiency. It decreases the development of caries on the permanent first molar in post-erupted phase. The results of this work confirm those of previous studies and show this material can be used safely in preventive and curative dentistry. This prospect might contribute to improving public health, particularly in Viet Nam and in other developing countries where the financial resources are limited

Der volle Inhalt der QuelleThe cucumber (Cucumis sativus L.) is a vegetable belonging to the family Cucurbitaceae, of great importance in Brazil. It is grown, preferentially in tropical climate, in high temperature conditions. It has a high economical, nourishing and social value because it generates direct or indirect jobs, requiring a labor demand from its cultivation to its commercialization. Due to the cultivation expression, the seed physiological and sanitary quality constitutes an important factor, being responsible for limitations in the product quality which is addressed to commercialization. So, with this work, one aimed at verifying the influence of Fusarium moniliforme on the seed physiological quality of two cucumber cultivars: Wisconsin and Caipira, through the hydric restriction inoculation technique, besides assessing the efficiency of the vigor tests for the stratification of the lots according to its physiological quality. The isolate of F. moniliforme was obtained from cucumber seeds. Each cultivar was divided into three lots of different physiological quality, differentiated by artificial aging. The treatments consisted in: Absolute witness; PDA + mannitol 0.8 Mpa; PDA pure; PDA + mannitol 0.8 Mpa + F.moniliforme; and PDA + F. moniliforme. The seed physiological quality was evaluated through tests carried out in laboratory conditions and in greenhouse. The hydric restraint was efficient to infect the seeds of two cultivars by pathogen, proving that this influences negatively in physiological quality of them and it can be transmitted by these. For cultivar Wisconsin, the tests of germination, cold and seedling growth were sensible to the lot stratification in two physiological levels. In the emergence of plants the speed emergence index, the root length and dry matter were able to classify the lots in three physiological categories. For the cultivar Caipira, the tests of germination and cold stratified the lots in two levels of vigor. In the test of growth of seedlings, the length of hypocotyls and root presented sensitivity to the classification of the lots in three physiological levels. For the plant emergence, the length of the hypocotyls and root and, dry matter showed themselves apt to the lot classification according to the physiological quality of them.
O pepino (Cucumis sativus L.) é uma hortaliça pertencente a família Cucurbitaceae, de grande importância no Brasil. É cultivado, preferencialmente, em clima tropical, em condições de temperatura elevada. Possui alto valor econômico, alimentar e social, pois gera empregos diretos e indiretos, exigindo uma demanda de mão-de-obra, desde seu cultivo até sua comercialização. Devido à expressão de cultivo, a qualidade fisiológica e sanitária das sementes constitui um fator importante, sendo responsáveis por limitações na qualidade do produto destinado à comercialização. Assim, objetivou-se com este trabalho verificar a influência de Fusarium moniforme sobre a qualidade fisiológica de sementes de duas cultivares de pepino: Wisconsin e Caipira, através da técnica de inoculação da restrição hídrica, além de avaliar a eficiência de testes de vigor para a estratificação dos lotes conforme a sua qualidade fisiológica. O isolado de F. moniliforme foi obtido de sementes de pepino. Cada cultivar foi dividida em três lotes de diferentes qualidades fisiológicas, diferenciadas pelo envelhecimento artificial. Os tratamentos consistiram em: Testemunha absoluta; BDA + manitol 0,8Mpa; BDA puro; BDA + manitol 0,8Mpa + F. moniliforme; e BDA + F. moniliforme. A qualidade fisiológica das sementes foi avaliada através de testes realizados em condições de laboratório e em casa de vegetação. A restrição hídrica foi eficiente para infectar as sementes das duas cultivares pelo patógeno, comprovando que este influencia negativamente na qualidade fisiológica das mesmas e, pode ser transmitido por estas. Para a cultivar Wisconsin, o teste de germinação, de frio e de crescimento de plântulas foram sensíveis para a estratificação dos lotes em dois níveis fisiológicos. Na emergência de plantas, o índice de velocidade de emergência, comprimento de raiz e massa seca foram capazes de classificar os lotes em três categorias fisiológicas. Para a cultivar Caipira, o teste de germinação e de frio estratificaram os lotes em dois níveis de vigor. No teste de crescimento de plântulas, o comprimento de hipocótilo e de raiz apresentaram sensibilidade para a classificação dos lotes em três níveis fisiológicos. Para a emergência de plantas, o comprimento de hipocótilo e de raiz e, massa seca mostraram-se aptos para a classificação dos lotes de acordo com a qualidade fisiológica dos mesmos.

Resumo: Estudos indicam que o principal fator a ser controlado para garantir a qualidade de produtos embalados é a concentração de oxigênio. Este controle poderá ser determinante na vida de prateleira do produto. Neste trabalho sistema (¿célula de absorção¿) e metodologia foram desenvolvidos para caracterizar um filme ativo contendo polietileno de baixa densidade e aditivo absorvedor de oxigênio disperso em sua matriz polimérica, o qual, na aplicação, compõe um sistema de embalagens multicamadas. Este aditivo é ativado pelo contato com a umidade e age de forma a seqüestrar o oxigênio dentro da embalagem. A caracterização do filme consistiu na determinação da capacidade e da velocidade de absorção de oxigênio pelo filme ativo, que foi acondicionado na célula, onde se realizou o controle da concentração de oxigênio via análises cromatográficas. O estudo da influência da temperatura e da umidade relativa na absorção do oxigênio foi conduzido segundo um planejamento fatorial composto 22. A dispersão do aditivo na matriz polimérica (microscopia óptica), a rugosidade da superfície do filme (MEV), a transmissão de luz (espectrofotometria UV-visível) e o grau de cristalização da resina (DSC) também foram estudadas. Os resultados indicaram que a variável de maior influencia na absorção de oxigênio é a umidade e que o filme apresenta sua máxima absorção e altas velocidades em temperaturas acima de 15°C e umidade acima de 81,2%. A dispersão do aditivo e a rugosidade na superfície do filme indicam melhores resultados em filmes em concentrações de aditivo acima de 5%. O filme ativo apresenta perda de transparência mesmo em baixas concentrações de aditivo (1%). O grau de cristalização do filme diminui com o aumento da concentração de aditivo, o que pode promover a difusão do oxigênio na resina favorecendo o contato entre o oxigênio e o aditivo, e assim, aumentar a absorção pelo filme
Abstract: Studies indicate that the main factor to be controlled to warrant the quality in packaged products is the oxygen concentration. This controlling can be determinant in the products shelf life. In this work, system (¿absorption cell¿) and methodology had been developed for characterize an active film containing low density polyethylene and a kind of oxygen scavenger additive dispersed throughout the polymer carrier, that, in the application, is part of a multilayer system packaging. This additive is activated by humidity contact and acts in a way of scavenging oxygen inside the packaging. The active film characterization consisted in determining the capacity and speed of oxygen scavenging by the film, that was kept inside the cell, where was carried out the oxygen concentration controlling by gas chromatography. The study of the temperature and the relative humidity influence in the oxygen scavenging was conducted by an experimental design composite 22. The additive dispersion in the polymer carrier (Optical microscopy), the surface roughness (MEV), the light transmission (spectrophotometry UV-visible) and the resin crystallization degree (DSC) were studied as well. The results indicated that the variable with the most influence in the oxygen scavenging was the relative humidity and the film showed the maxim scavenging and speed in temperatures above 15°C and relative humidity above 81,2%. The additive dispersion and the film surface roughness showed better results in film with concentrations above 5%. The film shows transparence lost even for low additive concentration (1%). The film crystallization degree reduces with the increase of additive concentration, this can promote the oxygen diffusion in the resin benefiting the contact between the additive and the oxygen and, though, it increases the scavenging by the film

Der volle Inhalt der QuelleIn this research, a new approach to cattle hide treatments, based on using a natural, food-grade resin, Shellac, to reduce microbial cross-contamination from the hides onto carcass meat, was developed and evaluated. The basis of this treatment is immobilisation of microorganisms on cattle hide’s hair and subsequent reduction of their transmissibility from the hair onto carcass meat during dressing of slaughtered cattle. Under in vitro conditions, treatment of samples of visually clean and dry hides with 23% Shellac-in-ethanol solution reduced sponge-swabbing recoveries of general microflora (TVC) by a factor of 6.6 logs (>1000-fold greater than the 2.9 log reduction observed by ethanol alone), and of generic E. coli (GEC) and Enterobacteriaceae (EC) by factors of at least 2.9 and 4.8 logs, respectively. The reductions of these three groups of microorganisms were superior to those achieved by a sanitizer rinse-vacuum hide treatment. Significantly greater reductions of TVC recoveries from hides were achieved when using higher Shellac concentrations (23.0% and 30.0% rather than 4.8-16.7%) and when Shellac solution temperatures were 20-40°C rather than 50-60°C. Furthermore, the Shellac-based treatment also markedly reduced the E. coli O157 prevalence (3.7-fold reduction) on natural, uninoculated hides, as well as the counts of E. coli O157 on artificially inoculated hides (2.1 log reduction) when compared to corresponding untreated controls. Under the conditions of a hide-to-meat direct contact laboratory-based model, treatment of hides (of varying visual cleanliness) with the 23% Shellac solution produced significant reductions of microbial transfer from treated hide onto sterile beef: up to 3.6 log10 CFU/cm2 of TVC, up to 2.5 log10 CFU/cm2 of EC and up to 1.7 log10 CFU/cm2 of GEC. TVC reductions of microbial transfer from treated hide onto beef achieved by the Shellac hide treatment were superior to those achieved by the comparative sanitizer rinse-vacuum hide treatment, but reductions of EC and GEC did not differ between the two hide treatments. In a small commercial abattoir with unsatisfactory process practices (slaughtering dirty cattle, inadequate process hygiene), treatment of hides with Shellac produced significant microbial reductions on skinned beef carcasses: 1.7 log10 CFU/cm2, 1.4 log10 CFU/cm2 and 1.3 log10 CFU/cm2 of TVC, EC and GEC, respectively. TVC reductions on skinned beef carcasses achieved by the Shellac hide treatment were superior to those achieved by the comparative sanitizer rinse-vacuum hide treatment, but reductions of EC and GEC did not differ significantly between the two hide treatments. These investigations produced the first scientific evidence that treatment of cattle hides with aim of immobilising microflora on the hair can be very successfully used to reduce carcass meat contamination during the skinning operation, thus improving the microbiological status of the final beef carcasses as well as the beef safety in general. To achieve the full potential of this new treatment in practice, further research aimed at its further technical optimization under real-life meat industry conditions is necessary.
