description: Introduction: Sarcopenia is a muscle disease that is linked to the effects ageing, chronic diseases, reduced physical activity and poor nutrition. Sarcopenia is associated with various adverse outcomes including falls, disability and mortality. In Ireland, there is a lack of readily available information on sarcopenia in older adults.
Aims and Objectives: The aim of this study was to describe the prevalence and associated factors of sarcopenia in community dwelling older adults attending a day hospital service in Ireland, using the latest European Working Group of Sarcopenia in Older People guidelines (EWGSOP).
Methods: A cross sectional study design was implemented. Community dwelling older adults attending a day hospital service in Ireland were invited to participate. The primary outcome was the diagnosis of sarcopenia using the EWGSOP guidelines. Secondary outcomes included elements of a Comprehensive Geriatric Assessment: cognition, nutrition, frailty and physical activity. A subgroup of participants were prescribed a accelerometer to objectively measure physical activity levels over 7 days.
Results: A total of 134 participants took part in the study with 41 in an accelerometer subgroup. The mean age of the study participants was 81.7 (SD +/- 7.1). Sixty-one percent (N=82) of the group were female. The prevalence of sarcopenia ranged from 27-37% depending on the assessment tool used to assess muscle strength. Sarcopenia was associated with ten different outcomes, irrespective of how muscle strength was measured. Independently associated factors differed depending on muscle strength test, except for older age. Sarcopenia, using grip strength and lower limb strength, was associated with increased amount of time spent in light physical activity measured using an accelerometer.
Conclusion: The prevalence of sarcopenia in the day hospital population ranges from 27-37%. The assessment tool used to assess muscle strength influences both the prevalence and associated factors of sarcopenia, highlighting a further need to standardise the assessment of sarcopenia. The range of associated factors highlights the multi-factorial nature of sarcopenia.

description: In this paper, we proposed a tri-band microstrip Bandpass Filter (BPF) for the application of GSM (1.8GHz), WiMAX (2.86GHz) and UWB (3.32– 5.12GHz). By integrating two narrow passbands filter with UWB filter; a tri-band response is achieved. The filter response performance is improved by introducing the asymmetric SIRs with Defected Ground structure (DGS). An appearance of transmission zeroes of the proposed structure guarantee the sharpness, the skirts of scattering parameters of triple-band Band pass filter (BPF). The proposed filter shows very low return loss of -42.57 dB, insertion loss of -0.04dB, and compact which shows that the filter is more efficient

description: Ce travail de recherche se centre sur le concept d’autorité et son appropriation par les enseignants novices. La littérature relate l’existence de difficultés en gestion de classe chez les débutants. Certains auteurs affirment que celles-ci sont étroitement liées avec leur vision du concept d’autorité. Ils essaient d’expliquer la nature de ses difficultés, en espérant qu’une fois identifiées, les novices arrivent à mieux les comprendre et les surmonter. Notre problématique a ici pour but, de nommer et définir les problèmes et remises en question, concernant l’autorité, d’un échantillon de six enseignantes primaire en début de carrière. Ayant le souci de définir au mieux l’autorité, centrale dans cette étude, nous traitons plusieurs dimensions de ce concept, en comparant les données issues de nos entretiens (d’une heure) et de nos observations en classe (d’une période scolaire), avec les explications des auteurs. Afin d’analyser au mieux les données à exploiter, l’intégralité des entretiens a été retranscrite et les informations recueillies grâce aux observations filmées ont été reportées dans un tableau d’étude. Outre la vérification de la validité de nos hypothèses, ce travail a permis d’apporter des réponses quant au type de difficultés rencontrées par les novices. Ainsi, nous avons pu recenser onze catégories de difficultés rencontrées par les enseignantes collaborant à la recherche. Parmi ces catégories, certaines recoupent la littérature parcourue, avant la phase de récolte des données sur le terrain (comme l’influence de leurs représentations et l’importance accordée à certaines valeurs). En revanche, d’autres, qui n’avaient pas été évoquées dans le cadre théorique, ont été découvertes grâce à l’analyse des résultats (comme la lassitude de répéter sans cesse les mêmes consignes). Cette étude nous a permis d’identifier deux postures (considérées comme extrêmes) qu’un enseignant peut adopter dans l’application de son autorité en classe. Grâce à l’analyse des données issues de nos observations et entretiens, il a été possible de définir la posture des enseignantes par rapport à ces extrêmes. Les similitudes dont ces débutantes font alors preuve, peuvent être interrogées comme potentielles causes du problème rencontré. L’aboutissement de cette recherche peut apporter des éléments de réponse à toutes personnes rencontrant des difficultés et s’interrogeant sur sa pratique de l’autorité.

description: In this thesis I explore the applicability of the ethnographic settlement-subsistence model of 'inland' versus 'coastal' cultural groups to archaeological site Edubu 2. Edubu 2 is located 1.17 km inland in the Caution Bay foothills, Papua New Guinea. Human occupation at the site dates from c. 2950 to c. 1360 cal BP. Ethnographers and colonial observers of the late nineteenth and early twentieth centuries, and some archaeologists of the late twentieth century, have developed a dichotomous settlement-subsistence model regarding two Caution Bay language and cultural groups. The Koita were described as an 'inland'-focussed people based on their settlement and subsistence patterns. The Motu, on the other hand, were described as 'coastal'-focussed people. To test this dual model, shell remains from Edubu 2 are identified, quantified and categorised into their originating habitats, in order to establish which resource zones were being accessed by the past inhabitants of the site. My analysis and subsequent interpretations suggest entirely coastal- focussed subsistence resourcing, and a shunning of freshwater environments by the past inhabitants of inland site Edubu 2. Thus, the model of 'inland' versus 'coastal' peoples cannot be applied to Edubu 2. In effect, this study questions the veracity of the original ethnographic model, as well as the total omission of shellfishing from colonial observations in the broader Port Moresby region.eng

description: La dichotomie entre cognition et affectivité a longtemps perduré dans la littérature scientifique et philosophique, tout comme dans le domaine éducatif. Toutefois, de nombreuses recherches actuelles dans le domaine de la psychologie soutiennent une vision plus intégrative dans laquelle le vécu émotionnel et les capacités intellectuelles s’influencent mutuellement. Partant de ce constat, si le sens du terme éduquer se réfère au développement de la personne dans son entièreté, l’évidence de l’enjeu de la prise en compte de la dimension socio-affective dans le contexte scolaire paraît indéniable. Seulement, force est de constater que les programmes sont chargés, que les échéances tombent les unes après les autres, que les différentes casquettes que doit porter l'enseignant sont multiples et que, bien souvent, le temps pour stimuler de manière active et soignée le développement socio-affectif de l'enfant, pourtant essentiel au bon apprentissage, manque. Et si la pédagogie assistée par un animal devenait l'outil par excellence ? Et si le chien, le meilleur ami de l'homme, pouvait prétendre à cette mission ? En effet, l'animal rassure, l'animal apaise ; l'animal fait rire, l'animal console. Il communique, il guide ; il accueille, il renforce, il valorise. Parmi eux, le chien a la particularité d'être un animal très sociable qui a une confiance en l'homme sans limite, un amour et une affection inconditionnels. Aux Etats-Unis, en Allemagne et même en Suisse alémanique, il n'est pas insolite de trouver, aux côtés des enseignants, ce genre d'animal à quatre pattes. Mais qu'en pensent des enseignant·e·s du Cycle 1 dans le canton de Vaud ? Comment s'y prennent-ils·elles pour développer la dimension socio-affective de leurs élèves ? Seraient-ils·elles disposé·e·s à embrasser un tel projet ? Sur quatre enseignantes interrogées au moyen d'entretiens semi-dirigés, il ressort que, bien que l'initiative leur paraisse séduisante, les contraintes qui l'accompagnent ne leur donneraient pas encore envie de tenter l'expérience si la direction de leur école le leur permettait.

description: © 2018 SAE International. All Rights Reserved. Digital engineering workflows, involving physico-chemical simulation and advanced statistical algorithms, offer a robust and cost-effective methodology for model-based internal combustion engine development. In this paper, a modern Tier 4 capable Cat® C4.4 engine is modelled using a digital workflow that combines the probability density function (PDF)-based Stochastic Reactor Model (SRM) Engine Suite with the statistical Model Development Suite (MoDS). In particular, an advanced multi-zonal approach is developed and applied to simulate fuels, in-cylinder combustion and gas phase as well as particulate emissions characteristics, validated against measurements and benchmarked with respect to the predictive power and computational costs of the baseline model. The multi-zonal SRM characterises the combustion chamber on the basis of different multi-dimensional PDFs dependent upon the bulk or the thermal boundary layer in contact with the cylinder liner. In the boundary layer, turbulent mixing is significantly weaker and heat transfer to the liner alters the combustion process. The integrated digital workflow is applied to perform parameter estimation based on the in-cylinder pressure profiles and engine-out emissions (i.e. NOx, CO, soot and unburnt hydrocarbons; uHCs) measurements. Four DoE (design-of-experiments) datasets are considered, each comprising measurements at a single load-speed point with various other operating conditions, which are then used to assess the capability of the calibrated models in mimicking the impact of the input variable space on the combustion characteristics and emissions. Both model approaches predict in-cylinder pressure profiles, NOx, and soot emissions satisfactorily well across all four datasets. Capturing the physics of emission formation near the cylinder liner enables the multi-zonal SRM approach to provide improved predictions for intermediates, such as CO and uHCs, particularly at low load operating points. Finally, fast-response surrogates are generated using the High Dimensional Model Representation (HDMR) approach, and the associated global sensitivities of combustion metrics and emissions are also investigated.

description: Der merkantile Minderwert spielt bei der Immobilienbewertung eine wichtige Rolle, insbesondere, weil die daraus resultierenden Wertabschläge beträchtlich sein können. In der Bewertungspraxis werden zwar verschiedene Modelle angewendet, allerdings existiert bislang kein Verfahren zur Ermittlung des merkantilen Minderwertes, das von den Gerichten uneingeschränkt anerkannt wird. Dies liegt im Wesentlichen daran, dass die bisherigen Verfahren auf Hypothesen bzw. Wahrscheinlichkeitsannahmen der Experten beruhen, sodass die Ergebnisse weder einen wissenschaftlich belastbaren Hintergrund noch plausible mathematische Rechenmethoden aufweisen. Gemäß Rechtsauffassung des BGH wird der merkantile Minderwert nur im Markt deutlich. Dies hat zur Folge, dass ein geeignetes Verfahren zu seiner Bestimmung nur mittels einer wissenschaftlichen Marktanalyse entwickelt werden kann. Um diesem Anspruch gerecht zu werden, wurde im Rahmen dieser Dissertation zum ersten Mal eine wissenschaftliche empirische Untersuchung deutschlandweit durchgeführt. Die erhobenen Daten wurden mittels einer Regressionsanalyse, jeweils bezogen auf die Ursachen (Feuchtigkeit, Hausschwamm, Kontamination, Setzungen, Bergschäden, Suizid, Mord oder andere negative Ereignisse), statistisch ausgewertet. Als Ergebnis wurden für jede der genannten Ursachen Schätzgeraden und Wahrscheinlichkeitsintervalle ermittelt.

description: The impact of depositing sol-gel coatings on the hydrophobicity of a bio-based material was investigated in this study. Bio-based materials have tendency to absorb large amounts of water due to their highly porous structure and presence of hydrophilic hydroxyl groups in their structure. For this purpose, two sets of silica sols were prepared to study the influence of catalysts and solvent concentration on the hydrophobicity of hemp shiv. The first set of silica sols were prepared using different acidic (hydrochloric acid and nitric acid) and basic (sodium hydroxide and ammonium hydroxide) catalysts while keeping the concentration of precursors and solvents constant. The hydrophobicity of sol-gel coated hemp shiv increased significantly when using acid catalysed sols resulting in water contact angles of up to 100° using sessile drop method. Therefore, the next set of silica sols were prepared with acidic catalysts using higher concentration of solvent. Hemp shiv coated with ethanol diluted sols showed better hydrophobicity when compared to undiluted sols. This difference in hydrophobicity can be attributed to the change in surface roughness. It was found that silica sols containing higher concentration of solvent provide a uniform coating layer covering the hemp shiv entirely. In contrast, undiluted sol coatings developed minor cracks on the hemp shiv surface as observed under 3D optical profilometer. Therefore, the use of diluted hydrophobic silica sols offers potential for treatment of extremely hydrophilic bio-based materials by sol-gel technology. For practical application of coatings on bio-based materials, diluted silica sols are of interest due to longer shelf life, reduced cost and lower environmental impact of precursors.

description: The divides between social groups in American society today extend from political opinion to lifestyle and emotions. A less explored area, however, is how these divides relate to potential divides in morality. The Habermasian conceptualization of the public sphere prioritizes deliberative reasoning as a way to solve moral conflicts. In contrast, this study argues that divides in reasoning and opinion are associated with divides in morality. To make the argument, this study focuses on the case of public debates over whether social media companies should deplatform Trump and his supporters in the aftermath of the January 6, 2021 Capitol insurrection. Public comments were obtained from a dataset compiled and released by Facebook Oversight Board. First, I used structural topic modeling to identify the reasoning and used the dictionary based on the Moral Foundations Theory to gauge moral foundations in each document. Then, I used statistical analysis to examine whether there was a correlation between specific reasoning and moral foundations. The results show that the pro- and anti-deplatforming camps in the debate are divided not only in reasoning, but also in morality. Supporters of deplatforming argue that it would fulfill tech companies’ public responsibility, and protect society at large. These arguments are correlated with the care foundation. In contrast, opponents argue that deplatforming Trump violated freedom of speech. This argument is correlated with the fairness, loyalty, and authority foundations, but not the care foundation. The findings support my argument that divides in reasoning should be analyzed with consideration of morality.

description: The paper discusses the use of autoclave as acceleration method for increasing the strength of bioconstruction materials. Three mixes where studied, they were prepared in order to have a CaO/SiO2 around 1. Hemp fibers were mixed with three different binder, Lime and silica fume mix (CaO/SiO2 = 1), cement and silica fume mix (CaO/SiO2 = 0,96) and cement, silica fume and lime mix (CaO/SiO2 = 0,95). Two curing temperature (110°C, 130°C and 180°C) used. The results show an increase of the strength of lime and silica fume mix from 0,5MPa to 4,4Mpa after autoclave at 110°C. While the cement and silica fume has an increase from 0,8Mpa to 1,5Mpa after autoclave at 110°C. The same mixes at autoclave 180°C show smaller increase in strength than autoclave at 110°C.

description: This paper unpacks how dynamic political and media systems shape the kinds of frames political actors champion, when and how they express support for frames and the implications of both for individual claimsmaking. To do so, we conduct a rigorous qualitative analysis of discourse during a two-week period in which the Florida legislature considered and passed the Marjory Stoneman Douglas High School Public Safety Act after a shooter killed 17 people in Parkland, Florida. We systematically explore how two framing dynamics – competition and amplification – shape what frames political actors champion and the relative effects of these dynamics on individual claimsmaking in 438 letters to the editor and op-eds appearing in mainstream outlets, 4,962 emails sent to Florida Governor Rick Scott, and 1,000 tweets. We find that amplification and competition shape the relative visibility of frames and the frequency with which individuals use these frames in their claimsmaking. Generally speaking, gun control and progressive groups selectively amplified frames associated with the emerging, student-led Never Again Marjory Stoneman Douglas movement and legislative frames that were consistent with their goals. This seems to have increased the visibility of these ideas in mainstream outlets and influenced claimsmaking insofar as individuals drew on amplified frames across the forums relatively frequently. This was not true of frames opposing gun control. Gun rights groups bickered with politicians and among themselves. As a result, gun rights frames were less prevalent in mainstream discourse and in individual claimsmaking.
Liability of the Crown: Are Immunities Unnecessary in Québec?

Liability of the Crown
Droit civil

description: The Crown has extensive powers and can sometimes cause injuries to those it governs through the use or misuse or these powers. Since there is no legislative scheme in place in Québec to create a specific regime for compensating these injured parties, the Crown is generally subject to the law of the land just like any other subject of the law. The separation of powers in Canada limits the power of the courts to review and evaluate Crown actions. The deference they must exercise in this review ensures that courts do not encroach on the legislative’s will to endow the Crown with its sovereign powers. This deference is relatively well understood in public law when it comes to declaring whether the use of these sovereign powers by the Crown was legal and within its mandate. The same principle of deference also applies to civil lawsuits in compensation. In Québec, the current form this deference takes is that the Crown is immune from normal rules of civil liability when it uses its core policy powers (such as regulatory powers), unless these powers were exercised in bad faith. This judicial scheme, however, appears unnecessary and needlessly complex. The definition of bad faith has been construed by the Supreme Court to include any action that would constitute a gross fault under the Québec civil law regime; in practice, the exercise of policy powers would command deference even if the standard was that of a simple fault. This means that the immunity only protects the Crown from injuries caused by the sort of action that it would not be liable for under the private law regime, making the immunity unnecessary.

description: To evaluate the effects of early aspirin therapy on the mean pulsatility index of both uterine arteries (utA PI) at 1st and 2nd trimester in women at risk of preeclampsia (PE). Uterine artery (utA) blood flow characteristics were obtained in 315 women, 73 women at risk for PE and early aspirin treatment (group 1), 124 without specific risk factors and no aspirin treatment (group 2) and 118 women with manifest PE (group 3). Mean utA PI of group 1 and group 2 were compared within and between the groups at the 1st and 2nd trimester time points. Furthermore, values at 2nd trimester were compared with those of group 3. Observed to expected mean utA PI ratio (O/E ratio) were calculated for comparison between the groups. Mean utA PI of group 1 was significantly higher in the 1st trimester compared to group 2 (1.74 vs. 1.47, p = .0117). In the 2nd trimester mean PI decreased significantly in both groups from 1.74 to 1.16 in group 1 and from 1.47 to 0.90 in group 2 (p p p p The prevalence of PE was 15.1% (11/73) in group 1 (4 early/7 late onset PE) and 4.7% (6/124) in group 2 (1 early/5 late onset). Mean utA PI and O/E ratio obtained in the 2nd trimester were higher in all PE cases with no significant difference between early and late onset PE (1.49/1.57 and 1.25/1.36 in group 1 and 0.80/0.97 and 0.77/0.99 in group 2). However, mean utA PI and O/E ratio decreased in all cases without PE in both groups, whereas mean utA PI was 1,37 and O/E-ratio was 1,29 in patients with manifest PE at admission, with significantly higher values in early onset than in late onset PE (1.45/1.31 vs. 1.07/1.02, p Our results show that early aspirin treatment leads to a decrease of elevated mean utA PI between 1st and 2nd trimester in patients at elevated risk for PE which is inferior to the decrease observed in women at standard risk for PE. While aspirin improves trophoblast invasion during early second trimester, vascular resistance remains well above average levels. Limited vascular remodeling capacity in the utero-placental perfusion area seems to be the explanation why aspirin does not abrogate PE in all women and has little effect on birth weight. Another explanation might be that a dose of 100 mg aspirin was used as compared to the 150 mg which is recommended today. Our findings underscore the need to study the effects of intervention already during the early stages of trophoblast invasion in the first trimester.

description: To determine the risk of wound complications by skin incision type in obese women undergoing cesarean delivery. Data sources: Electronic databases (MEDLINE, Scopus, and Ovid) were searched from their inception through August 2018. Methods of study selection: We included all randomized controlled trials and cohort studies reporting the placement of skin incision during cesarean section in obese women, defined as those with BMI ≥30 kg/m2. Studies were included if they compared one placement of skin incision with a different one as comparison group. The primary outcome was incidence of wound complications, while secondary outcomes included wound infection, hematoma, seroma, postpartum hemorrhage, and endometritis. Demographics and outcomes for each individual study identified were reported as part of the review. Meta-analysis was performed using the random effects model of DerSimonian and Laird, to produce summary treatment effects in terms of mean difference (MD) or relative risk (RR) with 95% confidence interval (CI). Sub-group analyses (vertical versus Pfannenstiel) were also reported. Tabulation, integration and results: Seventeen studies (including 3 RCTs; 8960 participants among the 15 non-overlapping studies) were included in the systematic review. Vertical incisions were associated with a relative risk of 2.07 (95% CI1.61–2.67) for wound complications compared to transverse incisions, however significant possible confounders were present. Studies were mildly-moderately heterogeneous (I2 44.81%, 95% CI 0.00–71.85%) with varying definitions of obesity and wound complications. High transverse incisions (3 studies, 218 participants) trend toward a lower risk of wound complications compared to low transverse incisions (RR 0.338, 95% CI 0.114–1.004). Vertical incisions may be associated with an increased risk for wound complications compared to transverse incisions for cesarean delivery in obese women. Randomized controlled trials are needed to evaluate optimal cesarean skin incisions for these women.

description: A series of smoke experiments were carried out in the Microgravity Science Glovebox on the International Space Station (ISS) Facility to assess the impact of low-gravity conditions on the properties of the smoke aerosol. The smokes were generated by heating five different materials commonly used in space vehicles. This study focuses on the effects of flow and heating temperature for low-gravity conditions on the pyrolysis rate, the smoke plume structure, the smoke yield, the average particle size, and particle structure. Low-gravity conditions allowed a unique opportunity to study the smoke plume for zero external flow without the complication of buoyancy. The diameter of average mass increased on average by a factor of 1.9 and the morphology of the smoke changed from agglomerate with flow to spherical at no flow for one material. The no flow case is an important scenario in spacecraft where smoke could be generated by the overheating of electronic components in confined spaces. From electron microcopy of samples returned to earth, it was found that the smoke can form an agglomerate shape as well as a spherical shape, which had previously been the assumed shape. A possible explanation for the shape of the smoke generated by each material is presented.Copyright 2015 American Association for Aerosol Research

description: Vaginal delivery is a well‐known risk factor for pelvic floor muscle (PFM) injuries, mainly when associated to prolonged labor, instrumental birth and perineal trauma such as episiotomy and perineal tears. The purpose of this meta-analysis was to test the hypothesis that episiotomy and severe perineal tear may increase the risk of pelvic floor damage. We performed a systematic literature search through electronic databases including MEDLINE via PubMed, LILACS via BVS, Embase via Elsevier and Cochrane Library up to January 2019. We included articles that reported as outcome one or more morphological aspects of the PFM evaluated by ultrasonography in primiparous women three to 24 months postpartum. This review is registered in the PROSPERO database (registration number: CRD42017075750). the final selection was composed of 18 articles for the systematic review, and 10 for the meta-analysis. Women with levator ani muscle (LAM) avulsion were 1.77 times more likely to have undergone episiotomy (OR = 1.77, CI 95% 1.25–2.51, five trials), 4.31 times more likely to have severe perineal tear (OR = 4.31, CI 95% 2.34–7.91, two trials). Women with defects in the anal sphincters were 2.82 times more likely to have suffered severe perineal tear (OR = 2.82, 95% CI 1.71–4.67, three trials). Both episiotomy and severe perineal tear are risk factors for LAM avulsion and anal sphincter injury, and this can be useful for identifying women who are at greater risk of developing PFM dysfunctions.

description: A series of smoke experiments were carried out in the Microgravity Science Glovebox on the International Space Station (ISS) Facility to assess the impact of low-gravity conditions on the properties of the smoke aerosol. The smokes were generated by heating five different materials commonly used in space vehicles. This study focuses on the effects of flow and heating temperature for low-gravity conditions on the pyrolysis rate, the smoke plume structure, the smoke yield, the average particle size, and particle structure. Low-gravity conditions allowed a unique opportunity to study the smoke plume for zero external flow without the complication of buoyancy. The diameter of average mass increased on average by a factor of 1.9 and the morphology of the smoke changed from agglomerate with flow to spherical at no flow for one material. The no flow case is an important scenario in spacecraft where smoke could be generated by the overheating of electronic components in confined spaces. From electron microcopy of samples returned to earth, it was found that the smoke can form an agglomerate shape as well as a spherical shape, which had previously been the assumed shape. A possible explanation for the shape of the smoke generated by each material is presented.

description: Phonon properties of AB (Bernal) stacked bilayer graphene (BLG) with various types of defects have been investigated theoretically. Forced Vibrational (FV) method has been employed to compute the phonon modes of disordered BLG. A downward linear shift of E2g mode frequencies has been observed with an increasing amount of defect concentration. Moreover, two identical E2g peaks have been observed in PDOS of the bilayer system where the individual layer contains 12C and 13C atoms respectively. From computed typical mode patterns of in-plane K-point optical mode phonons, it has been noticed that phonons become strongly localized around a few nanometers area at the presence of defects and localized modes increase with the increasing amount of defect concentration. The edge effect on the localized phonon modes has also been discussed for bilayer armchair graphene nanoribbons (BiAGNRs). The impact of defects on the phonon conduction properties has also been studied for BiAGNRs. My investigated results can be convenient to study the thermal conductivity and electron-phonon interaction of bilayer graphene-based nanodevices and to interpret the Raman and infrared spectra of disordered system.

description: Natural materials such as sugars or biopolymers are commonly used to stabilize and enhance the mechanical properties of earth-based building materials. Among them, brown seaweed polymers such as alginate have been recently used to improve the design of earth building materials. With its molecular structure, alginate can form a strong network with clay particles that strengthens the material. We here focus on the mix-design of earth based materials using a model earth-based material based on a mix of sand and kaolinite and a real raw earth material. We have worked on castable earth-based material. The fluidity of the castable earth has been reached by using s dispersant (hewapetaphosphate) to reduce the apparent yield stress of the material. The gelification of the alginate has been advantageously used to shorten the demoulding time. The effect of alginate on the compressive strength has been shown to depend on its dosage ad on the mineralogy of the soil. If alginate increases the strength of kaolinitebased samples, it does not influence the behavior of earth-based materials with swelling particles. We finally study the possibility to reinforce earth-based materials containing alginate with flax fibers.

description: The three-component reaction of 4-hydroxycoumarin, aldehyde, and aminopyrazole in the presence of a catalytic amount of L-proline in ethanol under reflux conditions provided the cyclized product (dihydrochromeno[4,3-b]pyrazolo[4,3-e]pyridine-6(7H)-one), whereas under similar reaction conditions, replacing aminopyrazole by 1,3-dimethyl-6-aminouracil provided the acyclic three-component product (6-amino-5-((4-hydroxy-2-oxo-2H-chromen-3-yl)methyl)-1,3-dimethylpyrimidine-2,4(1H,3H)-dione). This method is metal free and atom economical, and avoids column chromatographic purification as all the products can be purified by recrystallization.
