ABSTRACT
Extensive green roofs improve the provision of ecosystem services in urban environments, particularly in semiarid regions. The aim of this paper is to compare their thermal performance during six months between two rooms, one with a green roof and the other with a conventional roof, in Córdoba (Argentina). The room with a green (planting) roof showed a lower inside surface temperature since the beginning of the study than the control room (between 5–6°C of difference). During the selected period, the indicators such as temperature amplitude (the difference between the maximum and the average temperature) and the anti-interference characteristics of the layers to the outdoor air temperature are produced a better performance for the green roof compared to the conventional roof. The pattern of a better performance was consistent across the study for the green roof, characterized by a higher cooling and warming of the roof surface during the day and night, respectively. The green roof was more effective at blocking an upward heat flux during the day and suppressing heat loss during the night. Evaporation, conductive flux and climatic conditions seem to dominate the thermal performance of green roofs in areas with semiarid climate conditions.

ABSTRACT
Limestones are generally vulnerable to various weathering effects, hence, protection and consolidation of them is necessary. Locally available limestones of Northern Cyprus have been used in both historical buildings dated back to the 16th century for conservation applications and new buildings mostly as a cladding material. However, certain decay patterns exist on these stones. In the current study, the service life of Cyprus stones was inspected. Alkoxysilane-based consolidation and protection treatments were applied on new quarried stones to enhance the stone properties and aged stones to conserve and protect the architectural heritage. Service life assessment was performed by applying accelerated aging tests on both new and aged stones before and after treatments. The treatments improved the physical, mechanical and durability properties of the stones in terms of unchanging the water vapor diffusion resistance factor, decreasing the porosity and the water absorption ratio, increasing the ultrasound pulse velocity, the compressive and the flexural strengths, and improving the resistance of the stones against wetting-drying, freeze-thaw, salt crystallization and SO2 vapour effects. The combination of consolidation and protection treatment (K2) was more efficient on the properties of the stones compared to only protection treatment (K1) due to the better penetration capacity, higher decreasing ratio of the porosity, and higher improvement of the physical, mechanical and durability properties. The treatments also improved the properties of the aged stones; thus, it may be inferred that treatment would benefit the conservation of historical buildings.
PHYSICAL PROPERTIES AND ENVIRONMENTAL PERFORMANCE OF STEAM-CURED CONCRETE CONTAINING FLUE-GAS DESULFURIZATION GYPSUM
Authors: Jang Hongseok , So Seungyoung 
Published: February 2021

ABSTRACT
Flue-gas desulfurization (FGD) gypsum has occasionally been used as an additive to cement. Consequently, appropriate facilities are required to ensure the environmentally safe processing of FGD gypsum and the resulting cement material properties. Such facilities are yet to be developed because the amount of FGD gypsum used is still small when compared with the vast amounts of FGD gypsum generated. In this study, we analyze the effect of FGD gypsum addition on the physical properties, stabilization, and radon count of steam-cured mortar and compare its performance with air-cured mortar. Our results show that the steam-cured pozzolanic hydration products of ettringite and C-S-H promote the densification of the mortar structure, thereby resulting in nanopore size reduction and increased strength of FGD gypsum mortar subsequent to the steam-cured hydration process. Further, our environmental test results indicate that steam-cured pozzolanic materials composed of FGD gypsum are environmentally safer than air-cured cementitious materials.
Un Saint-Sépulcre à Beaulieu-lès-Loches
Authors: Bartal Renana 
Published: February 2021

Selon l’histoire de sa fondation, l’église abbatiale de Beaulieu-lès-Loches fut dédiée au Dominicum Sepulchrum quand Foulques Nerra, comte d’Anjou et fondateur du monastère, revint de son second pèlerinage à Jérusalem avec un fragment du Saint-Sépulcre. En raison de l’absence d’un plan de terrain centralisé, l’église de Beaulieu est rarement considérée comme une copie architecturale de l’édifice de Jérusalem. Bien que ce ne soit pas une copie explicite du Saint-Sépulcre, je soutiens que l’église abbatiale partageait plus que sa dédicace avec les monuments contemporains du Saint-Sépulcre. Cet article se concentre sur les aspects de l’église qui évoquent le Saint-Sépulcre : la disposition spatiale de son transept, sa liturgie, sa consécration suite au pèlerinage, sa fonction de lieu de sépulture et ses liens suggérés avec d’autres monuments locaux faisant référence à Jérusalem.
Pourquoi parler de civilisation juive médiévale ?
Authors: Denjean Claude 
Published: February 2021

L’article envisage les usages du terme et de la notion de civilisation au profit d’une histoire décloisonnée des juifs, distincte des études juives et insérée dans l’histoire de l’Occident médiéval. Après la lecture de la Méditerranée de Fernand Braudel, un panorama historiographique décrit les choix et les difficultés des historiens du judaïsme et des sociologues de la judéité, soucieux de comparatisme et observateurs des relations intercommunautaires. Les travaux récents examinés au prisme de la civilisation permettent de mieux se préserver des topoï et de saisir au sein d’une identité de longue durée la spécificité du Moyen Âge. Une civilisation médiévale juive s’épanouit à travers des procédés de distinction.
La R&D de défense en France : quels changements depuis la guerre froide ?
Authors: Moura Sylvain 
Published: February 2021

À travers une approche institutionnaliste de l’industrie d’armement, cet article mobilise les analyses issues des politiques publiques et de Jullien et Smith (2009 ; 2012) pour étudier l’évolution du système de recherche et développement [R&D] de défense en France. Il conclut que, si des adaptations au nouveau contexte géopolitique et économique ont eu lieu à la suite de la fin de la guerre froide, la politique de défense a choisi de maintenir le pays dans la course à l’excellence technologique militaire. Ce faisant, la relation entre l’État et les entreprises d’armement demeure structurante pour la viabilité de la R&D de défense.
Comprendre la production et la régulation des conflits environnementaux pour caractériser une trajectoire de sécurisation du risque

Cet article retrace l’évolution historique des institutions de protection contre les inondations dans la plaine de Grenoble, de 1219 à 1778. En nous appuyant sur la notion de contrat hydro-social (Novalia et al., 2009 ; Dill & Pelling, 2010), nous proposons de modéliser le rapport évolutif qu’entretiennent les habitants à la puissance publique relativement à la question des inondations. Déployant une démarche fondée sur l’institutionnalisme historique critique (Cleaver & Koenig, 2015), nos résultats dégagent trois configurations institutionnelles ou « agencements régulatoires » distincts, reflétant trois manières d’assurer la protection contre les inondations. En termes d’acteurs mobilisés, nous mettons ainsi en évidence un transfert progressif des missions de protection contre les inondations des communautés habitantes en direction de la ville de Grenoble puis de l’État. Le deuxième fait stylisé, relatif à la nature des assemblages institutionnels spécifiés historiquement, témoigne d’une évolution progressive de leur structuration : nous formulons l’hypothèse que cette dernière s’appuie successivement, à une période donnée et de manière prioritaire, sur l’un des « piliers » institutionnels (cognitif, normatif et réglementaire) introduits par Scott (1995). Nous montrons enfin que la nature des agencements spécifiés révèle leur niveau de cohérence et de robustesse, et que leur évolution peut se comprendre, parmi d’autres facteurs explicatifs, à l’aune de l’exacerbation ou du reflux des conflits et des inégalités qu’ils génèrent.

Objective:
The objective of the study was to determine the proportion of children requiring ocular surgery amongst new patients presenting to the Paediatric Ophthalmology Unit of the University College Hospital, Ibadan, over a 2-year period, to enhance planning and improve the efficiency of service delivery.

Methods:
The study was a retrospective review of records of all new patients aged 0–16 years who presented to the Paediatric Ophthalmology Unit of the University College Hospital, Ibadan, over a 2-year period (May 2015–April 2017). Information on age and gender, clinical diagnosis and indications for surgery and type of surgery scheduled were retrieved from the diagnosis register of the unit, and a descriptive analysis was performed.

Results:
Of the 1240 children who presented to the clinic within the study period, 142 (11.5%) needed surgical interventions. Their ages ranged from 1 month to 16 years, with a mean age of 6.4 ± 4.7 years. Seventy-nine (55.6%) of these were males. The most common indications for surgery were cataract and cataract-related indications (n = 122, 85.9%), followed by glaucoma and strabismus. Other less common indications for surgery were nasolacrimal duct obstruction and epibulbar dermoid.

Conclusion:
Paediatric cataract, the leading cause of childhood blindness in this environment, presents the greatest surgical burden in our unit. It should, therefore, be a major focus of personnel training and equipment procurement for paediatric ophthalmology services in our environment.
Scope of Genetic Testing for Inherited Cardiovascular Diseases in the Clinical Practice

Published: February 2021

Abstract
Inherited cardiac disorders are clinically and genetically heterogeneous group of disorders where sudden cardiac death is mostly the first clinical presentation. The available clinical markers are insufficient to make an accurate diagnosis, and therefore, molecular genetic diagnostics is an important tool for clinical decision-making. The advancements in technology have tremendously improved the affordability of genetic testing. In India, though genetic testing is being largely applied in the pediatric settings for chromosomal abnormalities and metabolic disorders, it is still at a nascent stage in the cardiology practice. Since cardiomyopathies and channelopathies have become actionable because of new interventional therapies, this article highlights the importance and need of genetic testing for inherited cardiac disorders by practicing cardiologists, in-view of the American College of Medical Genetics, American College of Cardiology, European Heart Rhythm Association guidelines. Incorporating cardiovascular genetic testing in the routine clinical practice can take it forward by greatly improving the scope of disease management.
Effective finiteness of solutions to certain differential and difference equations
Authors: Ingram Patrick 
Published: February 2021

AbstractFor
$R(z, w)\in \mathbb {C}(z, w)$
of degree at least 2 in w, we show that the number of rational functions
$f(z)\in \mathbb {C}(z)$
solving the difference equation
$f(z+1)=R(z, f(z))$
is finite and bounded just in terms of the degrees of R in the two variables. This complements a result of Yanagihara, who showed that any finite-order meromorphic solution to this sort of difference equation must be a rational function. We prove a similar result for the differential equation
$f'(z)=R(z, f(z))$
, building on a result of Eremenko.

Published: February 2021

ABSTRACTPalmoplantar involvement has been infrequently reported in leprosy and is an easily misdiagnosed entity. The institutional database of leprosy clinic from 2015 to 2018 was accessed. Details pertaining to demography, clinical presentation, comorbidities (if any), treatment received, and outcome were analyzed in leprosy patients with palmoplantar involvement. Among the 520 patients studied, the involvement of palms and/or soles was reported in 49 (9.4%) patients. Isolated palm involvement was the most frequent (26/49, 53.1%), followed by both palm and sole involvement (12/49, 24.5%) and sole involvement alone (11/49, 22.4%). A higher incidence of lepra reactions and disabilities was noted in patients with palmoplantar involvement than in those without (P < 0.0001). Palmoplantar involvement in leprosy, although uncommon, is associated with a higher risk of reactions and disabilities. A knowledge of this aspect of leprosy can help in maintaining a high index of suspicion and reduce misdiagnosis.

ABSTRACTKnowledge of the clinical progress of severe fever with thrombocytopenia syndrome (SFTS) and the associated predictors of mortality is important for providing appropriate treatment in severe cases. A multihospital retrospective study was conducted in three SFTS-endemic cities, in 2018. Of the 208 SFTS-confirmed cases, there were 189 survivors and 19 deaths. The median age was 64 years; 104 (50.0%) patients were men, and 188 (90.4%) were farmers. Furthermore, 203 (97.6%) patients reported fever and 70 (33.7%) reported fatigue. Most fatal cases had complications including multiple-organ failure, central nervous syndrome (CNS) abnormalities, and disseminated intravascular coagulation. During the fever phase, alanine transaminase, aspartate aminotransferase (AST), blood urea nitrogen (BUN), creatinine, D-dimer, glucose, hydroxybutyrate dehydrogenase, lactate dehydrogenase (LDH), procalcitonin, prothrombin time, and uric acid levels were higher in fatal than in nonfatal cases (P < 0.05). Creatine kinase (CK), CK-MB (CKMB), AST, and LDH levels were significantly lower in nonfatal than in fatal cases (P < 0.05). Central nervous syndrome abnormalities (odds ratio [OR] = 20.9, 95% CI: 4.3, 100), body temperature ≥ 38.5°C (OR = 23.2, 95% CI: 3.4, 158), BUN levels ≥ 6.4 mmol/L (OR = 9.9, 95% CI: 2.2, 44), CKMB levels ≥ 100 U/L (OR = 33.2, 95% CI: 5.8, 192), and LDH levels ≥ 1,000 U/L (OR = 8.3, 95% CI: 1.9, 37) were predictors of mortality. Our findings reveal that the presence of specific complications and laboratory parameters may serve as predictors of mortality and aid in early identification of severe SFTS cases in clinical practice.

Published: February 2021

Bu çalışmanın amacı sanatçı Nikhil Chopra’nın performans içeriklerinin, yöntemlerinin, farklılıklarının incelenmesidir. Bu bağlamda resim, fotoğraf, tiyatro, beden arasında şekillenen performanslarında Chopra’nın manzarayı ve portreyi nasıl ele aldığına, karakter yaratma tercihlerine, zaman kavramına, sanat tarihsel referanslara, bireysel anlatılara ve yöntemlere değinilmiştir. Ayrıca Chopra’nın, “Pamuk Üzerine Kömür, Sir Raja III-Bütün Bu Topraklarla Ne Yapacağım, Sir Raja III’ün Ölümü, Sir Raja II, Yog Raj Chitrakar: Bellek Çizimleri IX, Yog Raj Chitrakar: Bellek çizimleri VI ve Manzara Boyunca bir çizgi Çizmek: Çadır” performansları hikâyeleri, uygulama süreçleri ve sonuçları açısından ele alınmıştır.
Chopra’nın performanslarında toplumsal, kültürel ve tarihi olayları, bireysel geçmişine dayanan hikâyelerde kurguladığı; bu hikâyelerde geçmişinden hareketle bazı karakterler yarattığı ve anlatısını bu karakterler aracılığıyla aktardığı görülmüştür. Performanslarında manzara geleneksel yöntemlerle çizildiği halde; sürece yayılan performanslarında deneyimlenebilir, yaşayan, sabit olmayan bir form kazanmıştır. Portre, cinsiyet rollerine dayanan, tanınamayacak kadar değişen bedeninde yenilikçi yöntemlerle sunduğu bir biçim olmuştur. Performanslarında zamanın, mekânın, bedenin durağan olmadığı; Chopra’nın performanslarının hem öznesi hem nesnesi olduğu sonucuna varılmıştır.
Çalışma süresince Nikhil Chopra’nın web sayfasından, çalışmaları ve manifestolarından, Chopra ile yapılan röportajlardan faydalanılmıştır. Sanat tarihçisi, sanat eleştirmeni ve sanatçının kendi düşüncelerine yer verilmiştir. Kütüphane, arşiv ve süreli yayınlardan tarama, inceleme işlemi yapılmıştır.

Purpose: In this context, the current study aims to carry out an implementation analysis of knowledge network in Campania region, Italy. This region has implemented, using Measure 1, Measure 2 and Measure 16 of Rural Development Plan 2014-2020, an experimental model of AKIS.Methodology: The methodology was based on a living-lab approach where involved actors have an active role as co-innovators.Findings: The results give hints to implement, in the last period of the Cap 2014-2020, others experimental AKIS based on the Rural Developments Plans.Unique contribution to theory, practice and policy: The development of new agricultural practices and its spread to obtain more sustainable agriculture has become an important issue for researchers and policy makers. In particular, growing attention is paid to the Agricultural Knowledge and Innovation Systems (AKIS) expression used to describe the whole knowledge exchange system, the ways people and organisations interact within a country or a region. AKIS can include farming practice, businesses, authorities, research and can vary a lot, depending on the country or sector. However, the complexity of the AKIS implemented in Campania region requires particularly effective governance instruments and a continuous monitoring and evaluation processes to elicit innovation needs. Therefore, in the next CAP 2014-2020 measure related to advice (Art. 13 - COM (2018) 392 final) and ‘knowledge transfer and information actions’ (Art. 72 – COM (2018) 392 final) should be strategically integrated to implement modern and tailored advisory programmes based on different advisory work approaches to better meet the needs of all parties. This issue needs a testing time useful to better plan policy intervention for the next CAP.
