Sixty-two paintings, most of which were on paper, by Balinese artists, were sent on loan to Museum Puri Lukisan in Ubud, Bali, which had been set up in 1956 with help from the collector of the works, the Dutch artist Rudolf Bonnet. The exhibition travelled from Bali to Jakarta. The museum building on Bali had no climate control; so the paintings were sealed in simple, unmodified frames in an unobtrusive manner. Conditions inside and outside the sealed packages were recorded throughout the loan using tiny electronic dataloggers developed for testing within food and drugs packaging. The project demonstrated that relatively simple and inexpensive techniques proved highly effective in protecting the works from warm and humid tropical conditions. Resume «Retour a Bali: l'efficacite de l'utilisation de micro-climats au cours d'un pret d'œuvres sur papier entre les Pays-Bas et l'Indonesie» Soixante deux peintures, dont la plupart realisees sur papier par des artistes de Bali, furent envoyees en pret au musee Puri Lukisan in Ubud de Bali, qui avait ete cree en 1956 avec l'aide d'un collectionneur d'œuvres, l'artiste hollandais Rudolf Bonnet. L'exposition a voyage de Bali a Jakarta. Le batiment du musee de Bali n'avait pas de systeme de controle du climat; les peintures ont donc ete scellees d'une facon discrete dans de simples cadres sans qu'on ait eu a les modifier. Les conditions a l'interieur et a l'exterieur des paquets scelles ont ete enregistrees tout au long du pret en utilisant de petits capteurs electroniques mis au point pour evaluer les emballages de denrees alimentaires et de medicaments. Le projet a demontre que des techniques relativement simples et peu couteuses s'averent tres efficaces dans la protection des œuvres dans un climat tropical chaud et humide. Zusammenfassung „Zuruck nach Bali: Die Effektivitat von Mikroklimaten wahrend einer Leihgabe von Kunst auf Papier aus den Niederlanden nach Indonesien” 62 Gemalde von balinesischer Kunstler, die meisten auf einem Papiertrager, wurden an das Museum Puri Lukisan in Ubud, Bali, verliehen. Diese Museum war 1956 mit Hilfe des Sammlers der Gemalde, dem niederlandischen Kunstler Rudolf Bonnet, aufgebaut worden. Die Ausstellung reiste von Bali nach Jakarta. Das Museumsgebaude auf Bali hatte keine Moglichkeit der Klimakontrolle und so wurden die Gemalde in einfachen, unmodifizierten Rahmen gerahmt. Die Bedingungen innerhalb und ausserhalb der versiegelten Pakete wurden wahrend des gesamten Verleihs mit winzigen elektronischen Dataloggern gespeichert, die fur Test von Nahrungsmitteln und medizinischen Verpackungen entwickelt wurden. Das Projekt zeigte, wie relativ einfache und billige Methoden sich als sehr effektiv erwiesen, um die Werke von den feuchtwarmen tropischen Bedingungen zu schutzen. Resumen “Regreso a Bali: la efectividad en el uso de microclimas durante el prestamo de obras de arte sobre papel entre Holanda e Indonesia” Sesenta y dos pinturas, la mayoria de ellas sobre papel, de artistas balineses, fueron enviadas bajo prestamo al museo Puri Lukisan en Ubud, Bali, que en 1956 habian sido instaladas con la ayuda del coleccionista de los trabajos, el artista holandes Rudolf Bonnet. La exposicion viajo desde Bali a Yacarta. El edificio del museo en Bali no tenia control climatico; por tanto las pinturas fueron selladas en marcos sencillos de la manera menos intrusiva. Se registraron durante todo el proceso las condiciones dentro y fuera del embalaje usando unos minusculos medidores electronicos desarrollados para testar comida o droga empaquetada. El proyecto demostro que unas tecnicas relativamente simples y baratas eran muy efectivas en la proteccion de las obras de las condiciones de calor y humedad tropical. [ABSTRACT FROM AUTHOR]

To ensure future food security, improved agricultural management approaches are required. For many of those applications, precise knowledge of the distribution of crop types is essential. Various machine and deep learning models have been used for automated crop classification using microwave remote sensing time series. However, the application of these approaches on a large spatial and temporal scale is barely investigated. In this study, the performance of two frequently used algorithms, Long Short-Term Memory (LSTM) networks and Random Forest (RF), for crop classification based on Sentinel-1 time series and meteorological data on a large spatial and temporal scale is assessed. For data from Austria, the Netherlands, and France and the years 2015–2019, scenarios with different spatial and temporal scales were defined. To quantify the complexity of these scenarios, the Fisher Discriminant measurement F1 (FDR1) was used. The results demonstrate that both classifiers achieve similar results for simple classification tasks with low FDR1 values. With increasing FDR1 values, however, LSTM networks outperform RF. This suggests that the ability of LSTM networks to learn long-term dependencies and identify the relation between radar time series and meteorological data becomes increasingly important for more complex applications. Thus, the study underlines the importance of deep learning models, including LSTM networks, for large-scale applications. [ABSTRACT FROM AUTHOR]

Abstract: Down-core sediment pigment concentrations from four Northern European estuaries were measured using high-performance liquid chromatography (HPLC) to investigate phytoplankton community structure and preservation conditions over the last ca. 100 years where all sites have experienced different levels of eutrophication. Phytoplankton pigments have been shown to be useful biomarkers for phytoplankton community structure and abundance due to their taxonomic specificity. The pigment concentrations and sediment pigment inventory showed large variation between the four sites. Concentrations ranged from more than 6000 nmol/g OC to less than 100 nmol/g OC and the inventory integrated over the top 10 cm from more than 300 nmol/cm2 to less than 30 nmol/cm2 for total identified pigments. Good pigment preservation in Mariager Fjord (Denmark) reflected the almost permanently anoxic conditions. Pigments in Laajalahti (Finland) showed peak concentrations around the time of highest nitrogen loading events known from historical and modelled records over the past 100 years. In contrast, poor down-core preservation of pigments (especially carotenoids) was observed in the Ems-Dollard (The Netherlands) and Himmerfjärden (Sweden) estuaries. The Ems-Dollard site is an intertidal mudflat that experiences daily exposure to light and air, which enhances pigment degradation. In Himmerfjärden, resuspension is an important process affecting both the sedimentation rate and degradation properties. The different preservation conditions at the four sites were supported by the differences in two degradation indicators; the ratio of pheopigment-a to chlorophyll-a and total carotenoids to total pigments. Class-specific carotenoid pigments represented the dominant algal groups reported from each site, however, no distinct down-core changes in the pigment composition were observed at any of the four sites. This indicated that changes in plankton community structure on the group level have been limited over this time period or masked by low preservation of pigments. [Copyright &y& Elsevier]

Examines the implication of transabdominal chorionic villus biopsy for determining fetal karyotypes in pregnancy in the Netherlands. Aspects of the biopsy for the detection of fetal chromosomal defects; Advantages of the biopsy; Reliability of the biopsy.

Data from 3611 consecutive CVS (TC, N = 1780; TA, N = 1831) were analysed with emphasis put on influence of maternal and gestational age at CVS on the fetal loss rate less than 28 weeks. For TC-CVS the gestational age varied from 9.3-11.6 weeks, for TA-CVS from 9.3-20 weeks. Sampling efficacy at first attempt was 86.5 per cent and 95 per cent respectively. In 4.6 per cent an abnormal result was established. In older mothers (N = 2362) the fetal loss rate was significantly higher (p = less than 0.05) when sampled before 12 weeks (TC-CVS 6.2 per cent, TA-CVS 5.8 per cent). When the CVS (TA) was performed after 12 weeks the fetal loss rate decreased to 2.4 per cent. In 1079 younger women the fetal loss rate remained low (TC 2.8 per cent; TA less than 12 weeks 1.8 per cent; TA greater than 12 weeks 1.7 per cent) and was not influenced by gestational age at the time of sampling. We concluded both methods safe and reliable when the choice of application considers maternal age.
