ChemInform Abstract: Monolayers and Langmuir-Blodgett Multilayers of Discotic Liquid Crystals?
1990
The field of monolayer and multilayer films of discotic LCs is at its very beginning. The scope and limitations of this preparation method have not yet been explored, and little is known about the structures obtainable. However, the potential access to extraordinary, ordered thin films is fascinating, and will stimulate research in the future.
Experimental taphonomy in museums: Preparation protocols for skeletons and fossil vertebrates under the scanning electron microscopy
2008
Natural history institutions use different standards and methods to prepare and preserve skeletons of both modern and fossil vertebrates. These standards and treatments may be considered as taphonomic agents of museum collections. Modifications may occur during preparation, affecting the integrity of bone tissues and skeletons or their molecular and geochemical composition. The present evaluation uses a Scanning Electron Microscope (SEM) to analyze the most common preparation methods and standards. The aim of this paper is to evaluate preparation methods to determine those that provide the best SEM observations and those that best preserve osseous tissues and least damage fossil surfaces. I…
Synthesis and characterization of titanium dioxide and titanium dioxide–based materials
2021
Abstract The aim of the chapter is to describe some different preparation methods and characterization techniques for bare, supported, and coupled TiO2 samples used in different fields. Particular attention has been paid both to the fundamental aspects of the different TiO2 preparation and characterization methods and the practical applications that the results obtained can have. Various examples have been reported from the literature to demonstrate the usefulness that students and scientists working with TiO2-based materials in different research areas can derive from various characterizations.

Laparotomiskas brūces preperitoneālas infiltrācijas efektivitāte ar lokāliem anestētiķiem pēc abdominālām operācijām
2019
Pēcoperācijas sāpju līmenis ir svarīgs faktors pacienta atveseļošanās un dzīves kvalitātes atjaunošanas procesā pēc ķirurģiskās iejaukšanās. Darba mērķis ir samazināt pēcoperācijas sāpes un novērst opioīdu blaknes pacientiem pēc gastrektomijas; sasniegt ātrāku pacienta atveseļošanos, izmantojot preperitoneālu infiltrāciju ar Bupivakaīnu. Šis pētījums ir prospektīvs, neranomizēts un salīdzinošs, tika veikts no 2018. gada oktobra līdz 2019. gada maijam RAKUS “Gaiļezers”. Pētījumā tika novērtēti rādītāji Pētījuma grupā un Kontrolgrupā. Rezultāti parādīja, ka sāpju līmenis miera stāvoklī un kustības laikā, tāpat kā saņemto opioīdu daudzums Pētījuma grupā ir zemāks, nekā Kontrolgrupā. Tāpat pirm…
Når preposisjonar erstattar kasus : om preposisjonsobjekt (objektsadverbial) frå norrønt til moderne norsk
2006
Masteroppgave i Nordisk språk og litteratur 2006 - Høgskolen i Agder, Kristiansand Dette arbeidet har to hovuddelar. Den første delen er ei valensundersøking. Formålet med denne undersøkinga er å finne ut kva for valens verb som i moderne norsk krev preposisjonsobjekt, hadde på det norrøne språksteget. Den andre hovuddelen er ein analyse av preposisjonsobjekt i moderne norsk, med grunnlag i det teoretiske rammeverket i arbeidet, Lexicase Dependency Grammar (Starosta 1988). Sentrale prinsipp i Lexicase Dependency Grammar (LCDG) blir presenterte i kap. 2. I dette kapittel blir også metodiske spørsmål i samband med valensundersøkinga diskuterte, og korpusa som dannar grunnlag for undersøkingan…
Starting from the Origin: the Early Latin preposition de (and its companions)
2015
This paper explores the semantic network of the Early Latin preposition de (“from”) on the basis of an extensive investigation of the electronic corpus of Comedies by Plautus and Cato’s de Agricoltura, which represent a substantial sample of the oldest Latin attestations in an extensive and non-fragmentary form. Our approach is heavily based on Cognitive Grammar (Langacker 1987; 1991; Luraghi 2003), although we complement it with considerations on the use of prepositions in Latin elaborated in the framework of Functional Grammar (Pinkster 1990; 1991), as well as with arguments proposed in Linguistic Typology (Croft 1991). This approach allows an explicative account of the interconnections a…
Demonstration of an endocrine signaling circuit for insulin in the sponge Geodia cydonium.
1989
Abstract The existence of an insulin-mediated cell-to-cell signaling in the sponge Geodia cydonium is demonstrated in this study by molecular biological and immunological techniques. The sequence of a sponge cDNA clone encoding preproinsulin was analyzed for the first time and determined to comprise a high homology to human preproinsulin (60-80% homology). The predicted polypeptide of preproinsulin from sponge contains two disulfide bridges which link the A- to the B-chain. The intra-A chain disulfide bridge is absent. Applying immunological and electron microscopical techniques it is shown that insulin is produced in specialized cells (spherulous cells). Experimental evidence is presented …
Quality Indicators for Crisis Communication to Support Emergency Management by Public Authorities
2011
The purpose of this paper is to develop a framework for performance indicators to measure and improve crisis communication preparedness of public authorities. Such an instrument supporting organizational learning has not yet been developed for crisis communication. Literature is used to create a basis and the framework is derived from a process model with various phases integrating communication activities with crisis management. In the paper, the development of the instrument is explained and justified. Furthermore, an example of its use is provided in which the instrument is used for an auditor evaluation of a water contamination case. A next step for future research could be to analyze a…
