Monitoring peatland water table depth with optical and radar satellite imagery

2022

Peatland water table depth (WTD) and wetness have widely been monitored with optical and synthetic aperture radar (SAR) remote sensing but there is a lack of studies that have used multi-sensor data, i.e., combination of optical and SAR data. We assessed how well WTD can be monitored with remote sensing data, whether multi-sensor approach boosts explanatory capacity and whether there are differences in regression performance between data and peatland types. Our data consisted of continuous multiannual WTD data from altogether 50 restored and undrained Finnish peatlands, and optical (Landsat 5–8, Sentinel-2) and Sentinel-1 C-band SAR data processed in Google Earth Engine. We calculated rando…

Interactive decision support and trade-off analysis for sustainable forest landscape planning under deep uncertainty

2022

Sustainable environmental management often involves long-term time horizons and multiple conflicting objectives and, by nature, is affected by different sources of uncertainty. Many sources of uncertainty, such as climate change or government policies, cannot be addressed using probabilistic models, and, therefore, they can be seen to contain deep uncertainty. In this setting, the variety of possible future states is represented as a set of scenarios lacking any information about the likelihood of occurring. Integrating deep uncertainty into multiobjective decision support increases complexity, calling for the elaboration of appropriate methods and tools. This paper proposes a novel intera…

A novel ether core lipid with H-shaped C80-isoprenoid hydrocarbon chain from the hyperthermophilic methanogen Methanothermus fervidus.

1998

Abstract A new ether lipid core (designated as FU) was found in Methanothermus fervidus total lipid. Comparison with caldarchaeol showed lower mobility of FU on TLC and smaller molecular weight (m/z 1298) by 2 mass units on FAB-MS. Treatment of FU with HI followed by displacement with silver acetate afforded long chain alcohol acetate (ROAc), which was further saponified with mild alkali to its free alcohol (ROH). ROH is the long chain alcohol prepared from FU. The molecular weights of ROAc and ROH were shown by MS to be 1354 and 1186, respectively. These results suggested that the molecular formula of ROH was C80H162O4, and ROH had four hydroxyl groups, and one molecule of ROH was bound wi…

Modeling of the process of moisture loss during the storage of dried apricots

2011

[EN] Moisture content is a reference parameter for dried food because the growth of most microorganisms is inhibited below certain water activity levels. In addition, it has a determining influence on the evolution of important parameters, such as color and flavor, and on other properties and deterioration reactions, such as texture, oxidation processes and nutritional value. During the storage of some dried fruits, moisture is produced due to Maillard reactions and exchanged with the surrounding environment through the packaging. The evolution of dried foods during their shelf life depends on the storage conditions. The aim of this study is to analyze the evolution of the moisture content …

ChemInform Abstract: Synthetic O-Glycopeptides as Model Substrates for Glycosyltransferases.

2010

Abstract A new approach to O-glycopeptides of the glucosamine type is described. N-Urethane protected, peracetylated glucosamine is converted into its 1-thio (1-bromo) derivative and used for glycosylation of a variety of protected serine or threonine derivatives as acceptors. The urethane group is easily exchanged for the natural N-acetyl moiety and O-deacetylation is achieved with hydrazine/methanol. The resulting O-GlcNAc derivatives are subjected to an enzymatic galactosylation procedure using β-1,4-galactosyltransferase (EC 2.4.1.22) to furnish O-glycopeptides of the neolactosamine type.

Synthesis of phosphono dipeptides, inhibitors of cathepsin C

1998

Abstract Phosphono dipeptides containing glycine, glycylglycine or L-alanine at N-termini and racemic phosphonic acid analogues of aromatic amino acids, as well as racemic alicyclic aminophosphonates, exhibit moderate inhibitory activity towards cathepsin C. This activity is probably due to the binding of the phosphonate moiety by a positively charged part of the enzyme which is complementary to the carboxylate part of the synthetic dipeptide products of the enzymatic reaction.

Approche responsable pour le patrimoine : coopération, participation, documentation / Approccio responsabile al patrimonio architettonico: cooperazio…

2014

Nel quadro del Programma Italie Tunisie, l’esperienza del Progetto APER viene introdotta con riferimento ai diversi livelli e alle opportunità della cooperazione: tra realtà transfrontaliere, tra istituzioni dello stesso Paese e tra studiosi di diverse discipline. Passando ai contenuti scientifici, dopo aver illustrato il campo di applicazione e le potenziali ricadute, si pone l’accento sul tema dell’integrazione tra salvaguardia e valorizzazione, come sintesi teorica e operativa degli obiettivi del Progetto APER. Seguendo l’evoluzione dell’approccio al patrimonio architettonico, dall’origine dello stesso concetto allo sviluppo degli obiettivi della conservazione prima e della valorizzazion…

The professional report in initial teacher training in France. Le «mémoire professionnel» dans la formation initiale des enseignants en France

2007

07086; International audience; While the IUFM (University Institutes for Teachers' Training) are going to become part of universities, this article questions one of the bases validating the teachers' training: the professional report. This assessment concerns exercising teachers in having a critical mind towards their practical experience, because its purpose is to prepare teachers to adapt to the different types of pupils they are going to teach. This is the reason why the Government can only define this assessment briefly, even if they want to have better control over the teachers' training. To be precise concerning this assessment, the Government has to trust the teachers' trainers' cont…

Approximate energy functionals for one-body reduced density matrix functional theory from many-body perturbation theory

2018

We develop a systematic approach to construct energy functionals of the one-particle reduced density matrix (1RDM) for equilibrium systems at finite temperature. The starting point of our formulation is the grand potential $\Omega [\mathbf{G}]$ regarded as variational functional of the Green's function $G$ based on diagrammatic many-body perturbation theory and for which we consider either the Klein or Luttinger-Ward form. By restricting the input Green's function to be one-to-one related to a set on one-particle reduced density matrices (1RDM) this functional becomes a functional of the 1RDM. To establish the one-to-one mapping we use that, at any finite temperature and for a given 1RDM $\…
