Continuous scientific research and the increasing saturation of the medical market in Poland implements the possibilities of using advanced MR techniques including MRS in everyday practice. This method, which has so far been used primarily for research purposes, can bring measurable benefits to patients not only in terms of clarifying diagnosis and narrowing differential diagnosis, but also monitoring the course of various diseases and their treatment. Here we present the basic principles of performing and interpreting spectroscopic spectra and possible clinical applications and development prospects of MRS. The literature reviewed both Polish and foreign articles both historically and in the past 10 years. The paper presents methodological issues related to the proper performance of magnetic resonance spectroscopy (MRS) and spectral composition and the role of major metabolites, as well as current clinical applications and directions of MRS development.

Remote sensing techniques based on soil spectral characteristics are the key to future land management; however, they still require field measurement and an agrochemical laboratory for the calibration of the soil property model. Visible and near-infrared diffuse reflectance spectroscopy has proven to be a rapid and effective method. This study aimed to assess the suitability of multispectral data acquired with the agricultural digital camera in determining soil properties. This 3.2-Mpx camera captures images in three spectral bands – green, red and near-infrared. First, the reference data were collected, which consist of 151 samples that were later examined in the laboratory to specify the granulometric composition and to quantify some chemical elements. Second, additional soil properties such as cation exchange capacity, organic carbon and soil pH were measured. Finally, the agricultural digital camera photograph was taken for every soil sample. Reflectance values in three available spectra bands were used to calculate the spectra indices. The relationships between the collected data were calculated using the independent validation regression model such as Cubist and cross-validation model like partial least square in R Studio. Additionally, different types of data normalisation multiplicative scatter correction, standard normal variate, min–max normalisation, conversion into absorbance] were used. The results proved that the agricultural digital camera is suitable for soil property assessment of sand and silt, pH, K, Cu, Pb, Mn, F, cation exchange capacity and organic carbon content. Coefficient of determina-tion varied from 0.563 (for K) to 0.986 (for soil organic carbon). Higher values were obtained with the Cubist regression model than with partial least squares.

The article contains an extended report from the summer school “manuSciences’15. Manuscripts: From Fragments to Books – From Identifi cation to Interpretation” organised by the Freie Universitat Berlin and Ecole Pratique des Hautes Etudes, and held at Fraueninsel in Bavaria, on 6–12 September, 2015. The main aim of the gathering was to provide an opportunity for exchange of ideas and knowledge between researchers working on historical written sources, who belong to the fi eld of the humanities, and specialists, who represent exact sciences, and who are capable of furnishing new technical potential for manuscript research. P. Pludra-Żuk, herself a representative of the humanities, describes the new technical tools, which can be utilised in primary source research, and which allow for the acquisition of hitherto undisclosed information concerning the medieval scribal workshop (numerous types of materials research), non-invasive methods of reaching text fragments diffi cult to get to, or unreadable (Refl ectance Transformation Imaging, hyperspectral imaging, XRF), or partial automation of the reading and analytic process.

Artykuł zawiera podsumowanie szkoły letniej, zatytułowanej „manuSciences ’15. Manuscripts: From Fragments to Books – From Identification to Interpretation” (6–12 września 2015, Fraueninsel), zorganizowanej przez Freie Universitat Berlin i Ecole Pratique des Hautes Etudes. Założeniem omawianych warsztatów było stworzenie warunków dla wymiany doświadczeń pomiędzy badaczami zajmującymi się analizą źródeł, a specjalistami reprezentującymi nauki ścisłe, starającymi się stworzyć wsparcie techniczne dla tego typu badań. W artykule opisano wybrane narzędzia, wywodzące się z nauk ścisłych, które mogą znaleźć zastosowanie w badaniach źródłoznawczych, umożliwiając m.in. wydobycie dodatkowych informacji na temat średniowiecznego warsztatu (jak rożnego typu badania materiałowe), bezinwazyjne dotarcie do tekstów trudno dostępnych lub nieczytelnych (Reflectance Transformation Imaging, obrazowanie multispektralne, XRF), czy częściowe zautomatyzowanie procesu odczytywania i analizy tekstu źródłowego.

The article deals with the implementation of an 18th-century method of transferring graphic images onto ceramic substrates based on a contemporary graphic art workshop. Popularised in the 18th and 19th centuries in England, the technique called transferware used engraving matrices, and the decoration was transferred onto ceramics using tissue paper and subsequently fired in a two-stage process. An important element in the implementation of the new method of transferring graphics onto ceramics is the development of recipes for contemporary low-toxic or non-toxic ceramic paints in the basic colour range - vitreous and underglaze ceramic pigments. The pigments created and tested, due to the range of physical parameters studied, can be spectroscopically studied objects. The process of implementation of the transfer also describes the study of the image carriers, from intaglio to relief printing matrices, the development of recipes for the composition of graphic-ceramic paints, firing methods, methods of image application, and the papers used. Preliminary experience shows that not only the transfer of graphics - an image from a graphic matrix onto ceramics is possible, but also it produces interesting artistic effects without the use of toxic solvents. Recreating old methods of transferring graphics onto ceramics in combination with new technologies is an innovative idea. The method of transferring the matrix onto ceramics creates an innovative workshop and allows an interdisciplinary studio to operate within the structure of artistic printmaking. The aim of implementing the new method of technology is to use it for artistic solutions.

Artykuł dotyczy wdrożenia XVIII- wiecznej metody transferu grafiki na podłoża ceramiczne w oparciu o współczesny warsztat graficzny. Technika nazywana transferware, spopularyzowana w XVIII i XIX wieku w Anglii, wykorzystywała matryce rytownicze, a dekoracja była przenoszona na ceramikę za pomocą bibuły i wypalana w dwustopniowym procesie. Ważnym elementem wdrażania nowej metody transferu grafiki na ceramikę jest opracowanie receptur współczesnych małotoksycznych lub nietoksycznych farb ceramicznych w podstawowej gamie kolorystycznej – pigmenty ceramiczne naszkliwne oraz podszkliwne. Tworzone i testowane barwniki, ze względu na zakres parametrów fizycznych badanego zjawiska, mogą być obiektami badanymi spektroskopowo. Proces wdrażania transferu opisuje także badanie nośników obrazu, począwszy od matryc wklęsłodrukowych po wypukłodrukowe, opracowanie receptur składu farb graficzno-ceramicznych, metod wypału, sposobów nanoszenia obrazu, użytych papierów. Wstępne doświadczenia pokazują, że transfer grafiki – obrazu z matrycy graficznej na ceramikę jest nie tylko możliwy, ale daje ciekawe efekty artystyczne bez stosowania toksycznych rozpuszczalników. Odtworzenie starych metod transferu grafiki na ceramikę w połączeniu z nowymi technologiami jest nowatorskim założeniem. Metoda transferu matrycy na ceramikę tworzy innowacyjny warsztat oraz pozwala na działanie interdyscyplinarnej pracowni w strukturze grafiki artystycznej. Celem wdrożenia nowej metody techniki jest wykorzystanie jej do rozwiązań artystycznych.
