As already shown 3 years ago, the preoxidation of smooth (Ra < 0.05 µm) low carbon steel substrates in a furnace under a CO2 rich atmosphere at atmospheric pressure allows the formation of a wustite (Fe1-xO) layer which improves significantly the adhesion (> 55 MPa) of alumina coatings in spite of the rather low roughness (0.10 µm < Ra < 1.00 µm) of the oxidized surface. This contribution is devoted to a more precise study of the wustite layer and its interface with the alumina layer by X-ray diffraction (XRD), Mossbauer spectroscopy and scanning electron microscopy (SEM). Firstly the substrate was oxidized under different temperatures and durations in order to control the oxide layer thickness and structure. Secondly the substrate samples were preoxidized during 15 minutes at 1273 K under CO2 atmosphere and, afterwards, preheated by the plasma jet in air just before coating. In this case the analysis was focused both on the alumina splat formation and the interface between splat and the oxide layer. Only a non-continuous alumina layer (a few splats) was sprayed: this allowed surface analysis down to the substrate through the alumina layer and the interface. This method avoids any modification of the searched information by a complex specimen preparation as required in the case of transmission electron microscopy (TEM) for example. For the steel surface preheated in CO2 atmosphere, before spraying, SEM observations and XRD patterns showed the presence of a continuous oxide layer formed by wüstite crystals with an average size of 1-5 µm. After deposition, splats consisted of transitional alumina (γ phase) but the underlayer was no longer pure wüstite. XRD and Mossbauer identified magnetite at the surface of the oxide scale in contact with alumina. This can probably be considered as the result of a partial topotactic transformation of wustite into magnetite, since no morphological change of the oxide layer has been observed. It has been established that this transformation is a consequence of the pre-heating treatment, and not due to any reaction with alumina. It is worth noting that, under these conditions, γ alumina has a spinel structure analogous to that of the magnetite phase with which it was in contact: the alumina structure was possibly induced by that of the magnetite underlayer.
Thermal Behavior of Y-PSZ TBCs in situ Remelted During Their Deposition

Published: August 2022

In previous works, laser irradiation was associated to thermal spraying in the so-called MELTPRO process to improve the performance and the durability of TBCs. This study aims at presenting results concerning the thermal behavior of TBC's manufactured according to this process. Two types of severized thermal cycling were implemented: (i) “oxidizing” test: isothermal shocks were performed at different temperatures, ranging from 900°C to 1050°C down to 0°C; (ii) “quite non-oxidizing” test: thermal shocks were implemented from a temperature of 1100°C down to 50°C. Moreover, thermal annealing at 1100°C were performed to compare sintering phenomenon. TBC microstructure and its evolution during heat treating were characterized using image analysis, Knoop micro-indentation and XRD analysis. MELTPRO process was shown to increase twofold the lifetime of TBCs during isothermal shock tests. This is attributed to the fact that the columnar structure and the pore-crack architecture of remelted coatings improve the compliance property and decrease the permeability of TBCs. XRD analyses show that, in the Y-PSZ TBCs, the main phase is the metastable tetragonal (t’) phase both for as-sprayed and MELTPRO processed coatings. Moreover, remelted TBCs show a higher phase stability than as-sprayed TBCs during thermal shock tests: it seems that the remelted coatings have higher phase stability thanks to their pore architecture, which lead to a better compliance in relation to the thermo mechanical stresses, and so to a decrease in the stress variations undergone by the structure during the thermal cycles. During thermal annealing, it seems that MELTPRO processed coatings are less affected by sintering than as-sprayed coatings. Sintering phenomenon primarily concerns inter-lamellar cracks of non remelted areas. Besides, whatever the coating manufacturing process, the main remaining phase is the metastable tetragonal phase whatever the heat treating duration.

Published: August 2022

Yttria partially stabilized Zirconia (Y-PSZ) thermal barrier coatings (TBCs) have numerous applications as insulation layers onto gas turbine components. The main function of TBC is to enhance efficiency by increasing working temperature. These coatings are commonly manufactured using air plasma spraying. The characteristics of TBCs strongly depends on their pore and crack network architecture. Engineering the coating architecture by an adapted process is a prerequisite to modify TBC characteristics. Therefore, air plasma spray and in situ laser irradiation by diode laser processes were combined in this study to modify structural characteristics of TBCs. The coatings were remelted layer by layer during their deposition or alternately (i.e., an as-sprayed layer followed by an in situ remelted layer). This process was named MELTPRO. TBC apparent thermal conductivity was quantified implementing numerical computations based on 2-D real discrete structures. Coating thermal properties were correlated to their pore network architecture characteristics quantified by image analysis (i.e., nature, orientation, percentage, etc.). Moreover, thermal annealing at 1100°C were performed to compare sintering phenomenon of manufactured TBCs. Results show that the MELTPRO process permits: (i) to modify of the pore network architecture of as-sprayed TBCs. The porosity level increases by the in situ remelting process due to the formation of large horizontal cracks (as shown by image analysis). These horizontal cracks behave as thermal resistances and are responsible for the decrease of the coating thermal conductivity of about 30 % compared to the as-sprayed ones; (ii) to architecture differently the pore network for a constant thermal conductivity, because thermal conductivity and porosity level are not explicitly correlated; (iii) to improve the thermal insulation which remains unchanged after thermal annealing treatments: this seems to be due to the fact that the large cracks of remelted TBCs are less sensitive to sintering than inter and intra lamellar cracks of as-sprayed TBCs.
Collection of Nano-Powders Generated by Radio Frequency (RF) Plasma Spray Synthesis (PSS) Processing, using a Sampling Probe
Authors: Jia L. , Gitzhofer F.
Published: August 2022

A particle-sampling probe has been designed and constructed for the continuous collection of nano-powders produced by the plasma spray synthesis (PSS) process. The probe comprises a powder sampling line (inner tube), a quench gas line (outer tube) and a water-cooling jacket surrounding the outer tube. A sample holder is disposed at the exit of the inner tube to hold a standard 3.08 mm diameter TEM copper grid which is used to collect the powders by means of the pumping pressure differential. Quenching gas is introduced to the probe, via the outer tube to quench and entrain the as-synthesized clusters. After each sample collection event, the inner tube can be cleaned in-situ by means of a water injection, and then dried using a compressed gas flow. The results obtained to date indicate that the sampling probe location in the plasma reactor and the quenching gas flow rate employed are the most important parameters involved in the satisfactory operation of the sampling probe.
Study of Lamellar Microstructure of Plasma-Sprayed ZrO2-8wt.%Y2O3 Coatings
Authors: Wang W.-Z. , Li C.-J. , Sonoya K.
Published: August 2022

The lamellar microstructure of plasma-sprayed ZrO2-8wt.%Y2O3 (8YSZ) coatings was quantitatively characterized by a novel approach. The porous structure of the coating was visualized through infiltrating the tracer into voids in the coating combining with the energy dispersed X-ray line analysis of the tracer in the coating. The quantitative characterization parameters included the mean lamellar interface bonding ratio, mean lamellar thickness and width distribution of lamellar interface gaps. 8YSZ coatings were deposited by plasma spraying under different spray distances to reveal the effect of spray distance on the lamellar microstructure of plasma-sprayed 8YSZ coatings. The results showed that the maximum mean bonding ratio was 32% when the coating was deposited at spray distance from 65 to 80 mm. As spray distance was increased to 100-120 mm, the mean bonding ratio was reduced. The mean lamellar thickness was not significantly influenced by spray distance although it was found that the mean lamellar thickness tended to increase with the increase of spray distance from 80 mm. It was observed that lamellar interface gaps in the coating were mainly in submicrometer order. With the increase of spray distance, the mean width of interface gaps and fraction of wide interface gaps tended to increase.

O objetivo foi avaliar a qualidade química e sensorial do café variando-se o estádio de maturação do café para aplicação do fungo Cladosporium cladosporioides. O trabalho foi desenvolvido entre maio e agosto de 2019. O delineamento experimental foi em blocos casualizados, composto por cinco tratamentos, determinados em função do estádio de maturação para aplicação do Cladosporium: (testemunha (sem aplicação com 12% frutos verdes)), 70%, 50% e 30% de frutos verdes e aplicação do Cladosporium no pátio de secagem com 12% frutos verdes) e cinco repetições. A colheita e secagem de todas as parcelas de cafés seguiram o mesmo protocolo. Foram avaliadas as seguintes variáveis: análise sensorial, ocorrência de microrganismos e análises físicos químicas. Os dados foram submetidos à análise de variância e rede de correlações. Não houve diferenças significativas para os atributos avaliados devido às condições edafoclimáticas da lavoura que não foram favoráveis a ocorrência dos fungos deletérios a qualidade do café. Portanto, o uso do fungo Cladosporium cladosporioides para bioproteção da qualidade do café não se justifica em lavouras onde as condições não são favoráveis à ocorrência de fungos deletérios à qualidade do café, como baixa umidade e temperatura amena.

Coffee quality at different maturation stages, due to the application of Cladosporium cladosporioides
 
ABSTRACT: The objective was to evaluate the chemical and sensorial quality of coffee by varying the coffee maturation stage for application of the fungus Cladosporium cladosporioides. The work was carried out between may and august 2019. The experimental design was in randomized blocks, consisting of five treatments, determined according to the stage of maturation for application of Cladosporium: (control (without application with 12% green fruits)), 70 %, 50% and 30% of green fruits and application of Cladosporium in the drying yard with 12% green fruits) and five replications. Harvesting and drying of all coffee plots followed the same protocol. The following variables were evaluated: sensory analysis, occurrence of microorganisms and physical-chemical analyses. Data were submitted to analysis of variance and correlation network. There were no significant differences for the attributes evaluated due to the soil and climate conditions of the crop, which were not favorable for the occurrence of fungi deleterious to coffee quality. Therefore, the use of the fungus Cladosporium cladosporioides for bioprotection of coffee quality is not justified in crops where conditions are not favorable for the occurrence of fungi deleterious to coffee quality, such as low humidity and mild temperature.

Published: August 2022

In the implementation of the teaching and learning process, the use of learning media is still not optimally applied, besides seeing the obstacles experienced by students in learning mathematics, especially the material for rows and Series. So, a solution is needed to deal with the problems that occur. Based on the results of interviews conducted with a mathematics subject teacher, it was found that the teaching materials required by students to support mathematics learning with the demands of the use of technology were in the form of teaching materials that could be run on a computer or smartphone. This study aims to describe the development of learning media in the form of interactive multimedia using Adobe Animate on the material of sequences and Series for class XI Islamic High School (MAN) Bintan, which is valid and practical. The type of research used is Research and Development (R&D) using the ADDIE research model, which stands for Analysis, Design, Development, Implementation, and Evaluation; in this current research, it was only until the implementation stage. The subjects of this study were 20 students of class XI MAN Bintan. The types of data in this study are quantitative and qualitative data. Research instruments are media and material validation sheets and questionnaires for teacher and student responses to be checked for practicality. The results showed: (1) the validity of interactive multimedia based on the assessment of media and material experts got an average percentage of 81,37% validity with very valid criteria. (2) the practicality of interactive multimedia based on the questionnaire responses of teachers and students after using interactive multimedia got an average percentage of 89,34% practicality with very practical criteria.

The economic dimension of revitalisation in Poland - local authorities' perspective
Authors: Przywojska Justyna , Podgórniak-Krzykacz Aldona
Published: August 2022

Motives: The paper focuses on economic aspects of revitalisation of distressed areas and discusses results of the first and so far the only one survey on the subject conducted among the local governments in Polish municipalities. The article continues our previous research on sustainable revitalisation and focuses attention on one dimension of revitalisation – the local economy. We propose an innovative framework for economic revitalisation, which has been positively verified on the basis of the analysis of research results. The article also explores the views of local authorities on entrepreneurial participation in revitalisation.
Aim: The main objective is to develop a research method for analysing economic revitalisation and to identify local authorities’ perception of priority policy interventions for economic revitalisation in Polish municipalities. We also aim to verify the scale of entrepreneurs’ involvement in planning and monitoring revitalisation.
Results: Respondents show higher appreciation for economic revitalisation approach based on renovation and modernisation of buildings and technical infrastructure. The integrated approach to economic revitalisation was indicated by the fewest respondents. The low level or total lack of mobilisation of the business community around revitalisation in economic dimension can be considered as significant threats to the achievement of its objectives.
My home is no longer my castle. Collaborative housing as an element of sharing economy
Authors: Suszyńska Katarzyna , Lis Piotr , Rataj Zuzanna
Published: August 2022

Collaborative housing is considered a long-term housing option based on the idea of sharing space in a community-boosting manner. Residents share areas like laundry, utility or leisure rooms. On this basis the authors argue that housing may be treated as a commodity that could be shared just like sharing economy goods are. Thus the aim of this study is to evaluate the potential of collaborative housing from the sharing economy perspective. To achieve the aim, concepts of Curtis and Lehner (2019) and Curtis (2021) were applied to check what collaborative housing lacks to become a fully-fledged sharing economy entity. Apart from the nature of housing, which is by no means a fast moving consumer good, the lack of a digital platform that is the basis of most sharing economy entities, is the most visible difference between collaborative housing and sharing economy entities. Moreover, a questionnaire survey was conducted among prospective housing market users in Poland to check their awareness and readiness for this housing option. The research findings confirmed that they are still very low among housing market participants and private property is still considered considerably better than shared property. However, a tighter connection between collaborative housing and the sharing economy may provide the impetus for the young generation to enter this form of housing. The study is a contribution to the debate on collective housing options in Europe and may be considered novel as it attempts to conceptualize and position collaborative housing within the sharing economy context.
Unearthing Unknowns

English Abstract:
Over 7,500 American service members are unaccounted for from the Korean War, a legacy of the so-called forgotten war of the past century. But shifting political winds surrounding the US government’s care for war dead have breathed new life into the fading memory of these particular unnamed. Through the development of a systematic disinterment programme aimed at meeting congressional goals for the US military’s Missing In Action (MIA) accounting mission, the absent war dead from the Korean peninsula have ignited new debates over obligations to these missing combatants and their surviving kin. This article examines both the evolving forensic practice of the MIA accounting efforts as well as the bureaucratic attention now trained on the heretofore ‘forgotten’ missing. The commemorative and scientific interventions into the legacy of this past conflict reveal how the reappeared and returned dead become conscripted into projects of strategic national remembrance.

French Abstract:
Dans l’héritage de ce que l’on appelle la guerre oubliée du siècle dernier, il y a 7500 militaires américains de la guerre de Corée portés disparus. Mais l’évolution de la politique du gouvernement américain en matière de soins aux morts de la guerre a donné un nouveau souffle à la mémoire de ces inconnus. Grâce au développement d’un programme d’exhumation systématique visant à atteindre les objectifs du Congrès en matière de comptabilisation des personnes disparues au combat (MIA) par l’armée américaine, les morts de guerre absents de la péninsule coréenne ont suscité de nouveaux débats sur les obligations envers ces combattants disparus et leurs parents survivants. Cet article examine à la fois l’évolution de la pratique médico-légale des efforts de comptabilisation des MIA et l’attention bureaucratique désormais portée aux disparus jusqu’alors « oubliés ». Les interventions commémoratives et scientifiques sur l’héritage de ce conflit passé révèlent comment les morts réapparus et revenus au pays sont enrôlés dans des projets de commémoration nationale stratégique.
The Politics of Equivalence
Authors: McClellan Kate
Published: August 2022

English Abstract:
Transnational animal welfare NGOs working in Jordan enfold both animals and humans into their missions of care, making the claim that animal welfare is a form of human welfare. This approach requires making humans and animals equivalent enough to one another so that their lives, their economic prospects and their moral futures might be collectively addressed. In some cases, these ‘politics of equivalence’ draw on the legacies of dehumanisation and animalisation in colonial narratives of animal welfare; in others, it is a form of economisation and recalibration of life value. Tracing the central role of equivalence-making in transnational animal welfare work helps theorise how care is operationalised to be collective and efficient in global projects of aid. Collectivising human–animal care is in this case a highly effective politics of difference-making, collapsing the boundaries between human and animal life in Jordan while establishing difference between British and Jordanian life at the same time.

French Abstract:
Les ONG transnationales de protection des animaux qui travaillent en Jordanie intègrent à la fois les animaux et les humains dans leurs missions de soins, affirmant que le bien-être animal est une forme de bien-être humain. Cette approche exige de rendre les humains et les animaux suffi samment équivalents les uns aux autres pour que leurs vies, leurs perspectives économiques et leur avenir moral puissent être abordés collectivement. Dans certains cas, ces “politiques d’équivalence” s’appuient sur l’héritage de la déshumanisation et de l’animalisation dans les récits coloniaux du bien-être animal ; dans d’autres, il s’agit d’une forme d’économisation et de recalibrage de la valeur de la vie. Le fait de retracer le rôle central de l’établissement d’équivalences dans le travail transnational de protection animale permet de théoriser la manière dont les soins sont opérationnalisés pour être collectifs et efficaces dans les projets d’aide mondiaux. La collectivisation des soins humains-animaux est dans ce cas une politique très efficace de création de differences, qui abolit les frontières entre les vies humaine et animale en Jordanie tout en établissant des différences entre les vies britannique et jordanienne.

White pomegranate peel has many kinds uses, one of them as antimalaria. The unpleasant appearance and bitter taste of white pomegranate peel tablet can be covered by film coated using Kollicoat Protect. This research aimed to determine the effect of concentration and type of solvent used as a coating on the physical properties of the coated tablets and determine the optimum formula. Tablets were made using direct compression method and then coated using Kollicoat Protect. The optimization of coating formula was performed using a factorial design with design expert software ver 10.0. Responses used were tablet hardness, friability, disintegration time and increasing tablet mass. The results of this study showed that Kollicoat Protect cause increase of weight gain tablets and decrease the tablet friability, but prolong the disintegration time of tablets and decrease the tablet hardness while type of solvent can increase of weight gain tablets, tablet hardness, and decrease the tablet friability but prolong the disintegration time of tablets. The optimum combination formula was Kollicoat Protect at 13.6% and combination of water:alcohol (1:0.863) (w/v) with a theoretical response to weight gain of 2.340%; hardness 7.950 kp; friability 0.022%; and disintegration time 20.938 minutes.

Das Konstrukt Führungsstil beschreibt die Art und Weise, wie Lehrkräfte im Unterricht über eine Vielzahl an Situationen hinweg auf das Interagieren von Schüler*innen einwirken, um ein lehr-lernbezogenes Interaktionsgeschehen im Klassenzimmer zu verstetigen. In psychologischen Studien wird dieses Konstrukt als Prädiktor für den Lernerfolg von Schüler*innen beforscht. Darüber, wie Führungsstile durch die Realisierung von Interaktionspraktiken hergestellt werden, ist allerdings wenig bekannt. Der vorliegende Beitrag greift dieses Desiderat auf, indem Grundlinien eines Forschungsansatzes skizziert werden, der es ermöglicht, Stile interaktiven Führungshandelns als soziale Praxis im Umgang mit situativen Anforderungen der Interaktionssteuerung zu rekonstruieren. Vor dem Hintergrund einer kommunikationstheoretischen Beschreibung pädagogischen Handelns als Kontingenzbearbeitung werden gesprächsanalytische Vorschläge zur Analyse von Stilen interaktiven Führungshandelns adaptiert und für die mikroethnografische Untersuchung videographierter Unterrichtsinteraktionen aufgeschlossen. Anhand der Kontrastierung zweier Fallbeispiele wird gezeigt, wie mit einem solchen Ansatz neue Einsichten in die mikrologische Konstitution von Führungsstilen generiert und empirische Befunde zu situationsübergreifenden Selektionspräferenzen gewonnen werden können, die das Handeln von Lehrkräften in Auseinandersetzung mit alltäglichen Herausforderungen der Klassenführung kennzeichnen.
Structure and Power: an Emerging Landscape
Authors: Abramsky Samson
Published: August 2022

In this paper, we give an overview of some recent work on applying tools from category theory in finite model theory, descriptive complexity, constraint satisfaction, and combinatorics. The motivations for this work come from Computer Science, but there may also be something of interest for model theorists and other logicians. The basic setting involves studying the category of relational structures via a resource-indexed family of adjunctions with some process category - which unfolds relational structures into tree-like forms, allowing natural resource parameters to be assigned to these unfoldings. One basic instance of this scheme allows us to recover, in a purely structural, syntax-free way: the Ehrenfeucht-Fraïssé game; the quantifier rank fragments of first-order logic; the equivalences on structures induced by (i) the quantifier rank fragments, (ii) the restriction of this fragment to the existential positive part, and (iii) the extension with counting quantifiers; and the combinatorial parameter of tree-depth (Nesetril and Ossona de Mendez). Another instance recovers the k-pebble game, the finite-variable fragments, the corresponding equivalences, and the combinatorial parameter of treewidth. Other instances cover modal, guarded and hybrid fragments, generalized quantifiers, and a wide range of combinatorial parameters. This whole scheme has been axiomatized in a very general setting, of arboreal categories and arboreal covers. Beyond this basic level, a landscape is beginning to emerge, in which structural features of the resource categories, adjunctions and comonads are reflected in degrees of logical and computational tractability of the corresponding languages. Examples include semantic characterisation and preservation theorems, and Lovász-type results on counting homomorphisms.
Affine Completeness of Some Free Binary Algebras
Authors: Arnold André , Cégielski Patrick , Guessarian Irène
Published: August 2022

A function on an algebra is congruence preserving if, for any congruence, it maps pairs of congruent elements onto pairs of congruent elements. An algebra is said to be affine complete if every congruence preserving function is a polynomial function. We show that the algebra of (possibly empty) binary trees whose leaves are labeled by letters of an alphabet containing at least one letter, and the free monoid on an alphabet containing at least two letters are affine complete.
Solving Infinite Games in the Baire Space
Authors: Brütsch Benedikt , Thomas Wolfgang
Published: August 2022

Infinite games (in the form of Gale-Stewart games) are studied where a play is a sequence of natural numbers chosen by two players in alternation, the winning condition being a subset of the Baire space ωω. We consider such games defined by a natural kind of parity automata over the alphabet ℕ, called ℕ-MSO-automata, where transitions are specified by monadic second-order formulas over the successor structure of the natural numbers. We show that the classical Büchi-Landweber Theorem (for finite-state games in the Cantor space 2ω) holds again for the present games: A game defined by a deterministic parity ℕ-MSO-automaton is determined, the winner can be computed, and an ℕ-MSO-transducer realizing a winning strategy for the winner can be constructed.
Order-theoretic Trees: Monadic Second-order Descriptions and Regularity
Authors: Courcelle Bruno
Published: August 2022

An order-theoretic forest is a countable partial order such that the set of elements larger than any element is linearly ordered. It is an order-theoretic tree if any two elements have an upper-bound. The order type of a branch (a maximal linearly ordered subset) can be any countable linear order. Such generalized infinite trees yield convenient definitions of the rank-width and the modular decomposition of countable graphs. We define an algebra based on only four operations that generate up to isomorphism and via infinite terms these order-theoretic trees and forests.We prove that the associated regular objects, i.e., those defined by regular terms, are exactly the ones that are the unique models of monadic second-order sentences. We adapt some tools that we have used in a previous article for proving a similar result for join-trees, i.e., for order-theoretic trees such that any two nodes have a least upper-bound.
A Note on Calculi for Non-deterministic Many-valued Logics
Authors: Kaminski Michael
Published: August 2022

We present two deductively equivalent calculi for non-deterministic many-valued logics. One is defined by axioms and the other – by rules of inference. The two calculi are obtained from the truth tables of the logic under consideration in a straightforward manner. We prove soundness and strong completeness theorems for both calculi and also prove the cut elimination theorem for the calculi defined by rules of inference.
Morphisms and Minimisation of Weighted Automata
Authors: Lombardy Sylvain , Sakarovitch Jacques
Published: August 2022

This paper studies the algorithms for the minimisation of weighted automata. It starts with the definition of morphisms — which generalises and unifies the notion of bisimulation to the whole class of weighted automata — and the unicity of a minimal quotient for every automaton, obtained by partition refinement. From a general scheme for the refinement of partitions, two strategies are considered for the computation of the minimal quotient: the Domain Split and the Predecesor Class Split algorithms. They correspond respectivly to the classical Moore and Hopcroft algorithms for the computation of the minimal quotient of deterministic Boolean automata. We show that these two strategies yield algorithms with the same quadratic complexity and we study the cases when the second one can be improved in order to achieve a complexity similar to the one of Hopcroft algorithm.

Background: People with a migration background are underrepresented in dementia research and disfavored in assessment and treatment, and many foreign-born individuals with dementia remain undiagnosed. Objective: The aim of this study was to examine whether there is inequality in the clinical assessment of dementia between native and foreign-born individuals in Sweden. Methods: Information was gathered retrospectively from a cohort of 91 native and 36 foreign-born patients attending four memory clinics in Skåne, Sweden. Data included information on cognitive test results, cerebrospinal fluid biomarkers, scores at structural imaging scales of global cortical atrophy (GCA), medial temporal lobe atrophy (MTA) and the Fazekas scale, laboratory measures of thyroid-stimulating hormone, calcium, albumin, homocysteine, hemoglobin, cobalamin (vitamin B12), and folate (vitamin B9), contact with health care, and treatment. Results: Foreign-born patients had lower educational level and scored lower on Mini-Mental State Examination and Clock Drawing Test (p < 0.001–0.011). Relatives initiated contact with health care to a higher extent in the foreign-born group (p = 0.031). Foreign-born patients had less white matter lesions (p = 0.018). Additionally, Alzheimer’s disease (AD) biomarkers were significantly less used in foreign-born patients to support an AD diagnosis (p = 0.001). No significant differences were found for scores on GCA and MTA, laboratory measures, or initiated treatment. Conclusion: Although native and foreign-born patients were predominantly homogenous regarding examined variables, differences in the diagnostic process and underlying biological correlates of dementia exist and need to be further investigated in a larger sample.

Background: Self or home-administered cognitive screening instruments (CSIs) can reduce barriers to the early detection of mild cognitive impairment (MCI) and dementia. Objective: To examine the acceptability and diagnostic accuracy of a caregiver-administered CSI, the Quick Memory Check (QMC). Methods: Components of the Quick Mild Cognitive impairment (Qmci) screen (orientation, verbal fluency, and logical memory) were re-weighted to create the QMC, scored out of 100 points. Participants, attending a university hospital memory clinic, were provided administration instructions beforehand. Area under the curve (AUC) scores, adjusted for age and education, were compared with the Qmci screen and Montreal Cognitive Assessment (MoCA). Caregivers or family scored the QMC. Results: In all, 366 participants were recruited; 53 with subjective memory complaints (SMC), 74 with MCI, 193 with dementia, and 46 normal controls. Median QMC scores for controls were 70±13 versus 60±20 for SMC, 52±18 for MCI, and 31±21 for dementia. The QMC had excellent accuracy (AUC 0.97) for cognitive impairment (MCI/dementia from controls), similar to the Qmci screen (AUC 0.98, p = 0.17) and MoCA (AUC 0.95, p = 0.13). At a cut-off of <52/100, the QMC had 83% sensitivity and 100% specificity for cognitive impairment. The QMC had lower accuracy differentiating MCI from SMC (AUC 0.73), albeit similar to the MoCA (AUC 0.70). Conclusion: The QMC, administered by caregivers in advance of clinic, compared favorably to established CSIs scored by trained raters. This caregiver, home-administered CSI is acceptable and can identify cognitive impairment, potentially improving efficiency by reducing testing time and patient stress in busy clinical settings.

A typical case of producing records within the domain of conservation of cultural heritage is considered. During condition and collection surveys in memory organisations, surveyors observe types of multiple components of an object but without creating a record for each one. They also observe the absence of components. Such observations are significant to researchers and are documented in registration forms but they are not easy to implement using popular ontologies, such as the CIDOC CRM which primarily consider individuals. In this paper techniques for expressing such observations within the context of the CIDOC CRM in both OWL and RDFS are explored. OWL cardinality restrictions are considered and new special properties deriving from the CIDOC CRM are proposed, namely ‘typed properties’ and ‘negative typed properties’ which allow stating the types of multiple individuals and the absence of individuals. The nature of these properties is then explored in relation to their correspondence to longer property paths, their hierarchical arrangement and relevance to thesauri. An example from bookbinding history is used alongside a demonstration of the proposed solution with a dataset from the library collection of the Saint Catherine Monastery in Sinai, Egypt.

The present study aimed to assess the presence of Canine parvovirus 2 (CPV-2) antibodies in both vaccinated and unvaccinated dogs. The canine parvovirus disease in dogs was monitored by the use of live attenuated and killed vaccines besides new generation vaccines were also being developed for the control strategy. A total of 542 serum samples from different regions of Andhra Pradesh were used for the study. The age, sex, breed, and vaccination status were noted. The seroprevalence of canine parvovirus infection was studied by employing the methods of indirect ELISA and haemagglutination inhibition (HI) assay. The CPV infection rate was recorded as 94.65% in vaccinated and 72.50% in unvaccinated by indirect ELISA. Haemagglutination inhibition assay could detect 56.10% in vaccinated and 16.42% in unvaccinated ones. The titres ranged from 419 to 2337. Vaccinated dogs had more antibodies than the unvaccinated ones thus indicating the presence of antibodies in all the dogs suggesting that CPV infection is ubiquitous and natural infection of CPV aids in boosting immunity.

Provisions on Inheritance Law in Indonesia are regulated in Islamic Inheritance Law, Customary Inheritance Law, and Dutch Inheritance Law (Inheritance Law of the Civil Code). In terms of the territory in Indonesia and the diversity of culture, religion, and customs in the kinship system in each region affect the enforcement of Inheritance Law in Indonesia. However, problems often arise between the applicable law in religion and the application of local customs. The research was conducted using the Empirical Normative Legal Research Method, where the Law acts as a Norm (Legislation) by taking into account social realities. The results of the study stated that Islamic Inheritance Law was implemented by postulating the basis on the Al Quran and Hadith contained in the Compilation of Islamic Law. Applies to adherents of the Islamic religion and includes Indigenous Peoples who submit themselves to religious law.Keywords: Islamic Law; Inheritance; Indonesia AbstrakKetentuan tentang Hukum Waris di Indonesia diatur dalam Hukum Waris Islam, Hukum Waris Adat, dan Hukum Waris Belanda (Hukum Waris KUHPerdata). Dalam hal wilayah di Indonesia dan keberagaman budaya, agama, dan adat istiadat dalam sistem kekerabatan di tiap daerah mempengaruhi keberlakuan Hukum Waris  di Indonesia. Namun seringkali permasalahan timbul antara Hukum yang berlaku dalam agama dengan keberlakuan adat daerah setempat. Penelitian dilakukan dengan Metode Penelitian Hukum Normatif Empiris, dimana Hukum bertindak sebagai Norma (Perundang-undangan) dengan memperhatikan kenyataan sosial. Hasil penelitian menyatakan bahwa Hukum Kewarisan Islam dilaksanakan dengan mendalilkan dasar pada Al Quran dan Hadits yang termaktub dalam Kompilasi Hukum Islam. Berlaku bagi penganut agama Islam dan melingkupi juga Masyarakat Adat yang menundukkan diri pada hukum agama.       Kata Kunci: Hukum Islam; Waris; Indonesia
