Réduire les risques de chaleur extrême pour les personnes âgées : communiquer les risques et renforcer la résilience
Authors: Eady Allison , Dreyer Bianca , Hey Brandon , Riemer Manuel , Wilson Anne
Published: July 2020

Introduction

Les changements climatiques mondiaux entraînent des vagues de chaleur qui ont une incidence disproportionnée sur les personnes âgées et divers autres groupes socialement vulnérables. Afin d’atténuer les risques associés aux épisodes de chaleur extrême, il est essentiel d’élaborer et de promouvoir des ressources permettant de faire face à ces épisodes. Une meilleure compréhension du rôle de la perception des risques et des facteurs qui les influencent permettra d’améliorer les réactions du public aux événements menaçants, en particulier chez les personnes âgées.

Méthodologie

Cette étude à méthodologie mixte visait à examiner la perception des risques et les pratiques d’adaptation des personnes âgées en effectuant des entrevues qualitatives (n = 15) et une enquête (n = 244) auprès de personnes âgées de la région de Waterloo (Ontario).

Résultats

Les personnes âgées ont fait preuve d’une connaissance relativement précise des risques, comme l’indique le lien entre les mesures du risque réel et la perception de leur risque personnel. Alors que l’on associe souvent la vulnérabilité à la chaleur à une perception inexacte du risque, dans notre échantillon, cette vulnérabilité semble plus fortement liée à la situation sociale et à l’accès aux ressources. Les participants ont cité les liens sociaux comme des ressources importantes pour la résilience et ont mentionné la stigmatisation entourant la vulnérabilité ainsi que d’autres normes sociales comme des obstacles à la recherche de soutien.

Conclusion

L’une de nos constatations importantes est la relation positive entre la perception des risques par les participants et le risque réel de subir les conséquences négatives d’une chaleur extrême, alors que les problèmes de préparation aux situations d’urgence et de réduction des risques sont souvent présentés comme des questions de sensibilisation aux risques plutôt que de situation sociale et d’inégalité. Outre l’augmentation des ressources publiques pour composer avec la chaleur extrême, la communication sur les ressources, la promotion des liens sociaux et la réduction de la stigmatisation peuvent s’avérer des aspects cruciaux dans l’augmentation de la résilience des personnes âgées face aux vagues de chaleur.

The Importance of Initial Public Offering for Capital Market Development in Developing Countries
Authors: Pešterac Aleksandra
Published: July 2020

The first issue of shares is the key moment in the life cycle of any company that was not previously listed on a stock exchange. Considering the fact that transformation into a public open joint stock company brings along a number of advantages and challenges, it would be of great importance to possess knowledge about initial public offering (IPO) issuing activity, as well as stay updated with the number and value of globally realised IPOs. The aim of the paper is to use the comprehensive analysis of IPOs realisation process in order to point out the importance of going public, having in mind both the corporations and investors in the capital market, as well as the economy as a whole. In accordance with the set goal, the paper will present the effects of the realised IPO processes in the countries of Western Europe, China, Japan and the USA. When it comes to developing countries, the IPO of shares on a stock exchange is of special importance, since it contributes to the further development of capital market. Due to the particularity of the Serbian macroeconomic environment, the trends of privatisation process, the insufficient protection of investors, the high level of information asymmetry and the lack of corporate education, there have been no IPO processes realised on the Belgrade Stock Exchange over the past eight decades.
Effect of goose parvovirus and duck circovirus coinfection in ducks
Authors: Liu Jie , Yang Xiaoxia , Hao Xiaojing , Feng Yongsheng , Zhang Yuli , Cheng Ziqiang
Published: July 2020

Introduction

Coinfection of goose parvovirus (GPV) and duck circovirus (DuCV) occurs commonly in field cases of short beak and dwarfism syndrome (SBDS). However, whether there is synergism between the two viruses in replication and pathogenicity remains undetermined.

Material and Methods

We established a coinfection model of GPV and DuCV in Cherry Valley ducks. Tissue samples were examined histopathologically. The viral loads in tissues were detected by qPCR, and the distribution of the virus in tissues was detected by immunohistochemistry (IHC).

Results

Coinfection of GPV and DuCV significantly inhibited growth and development of ducks, and caused atrophy and pallor of the immune organs and necrosis of the liver. GPV and DuCV synergistically amplified pathogenicity in coinfected ducks. In the early stage of infection, viral loads of both pathogens in coinfected ducks were significantly lower than those in monoinfected ducks (P < 0.05). With the development of the infection process, GPV and DuCV loads in coinfected ducks were significantly higher than those in monoinfected ducks (P < 0.05). Extended viral distribution in the liver, kidney, duodenum, spleen, and bursa of Fabricius was consistent with the viral load increases in GPV and DuCV coinfected ducks.

Conclusion

These results indicate that GPV and DuCV synergistically potentiate their replication and pathogenicity in coinfected ducks.

Cross-border Islamic identity: Turkish foreign policy under the Justice and Development Party government
Authors: Alwan Batool Hussein , Khudair Shoroq Ayad
Published: July 2020

This study attempts to investigate a contemporary identity model that was not familiar with modern Islamic thought, which is an Islamic identity that transcends national borders. More precisely, it is a metaphor for a suprano-geopolitical investment in the identity field, rooted in modern Islamic history. Yes, the Islamic history in general had abounded with this type of investment, as its literature abounded with the global Islamic nation’s discourse, but the effectiveness of access across national borders and the ability to override the latter is a reality that necessitated an axiom in the presence of the national state model defined geographically, in the Islamic world, that it is a transient contemporary Islamic identity carried by A political entity - a state - with Islamic roots and an imperial heir, trying to use the identity dimension to implement a cross-border political agenda, depicting a pragmatic political stance, as it invests its religious identity in building its soft power and military power in predominantly Muslim areas, establishing a network of Desires with the currents of political Islam in them, especially those areas that were part of its imperial geography or strategic depth, it is the contemporary Turkish political system under the government of the "Justice and Development" party, with which the impact and role of the variable of the Islamic identity "the new Ottoman identity" has strengthened in Contemporary Turkish foreign policy trends.

Three-dimensional simulation of acidizing process in carbonate rocks using the Darcy–Forchheimer framework
Authors: Liu Piyang , Ren Xiaoxia , Kong Liang , Yao Jun
Published: July 2020

Acidizing is an economical and effective practice to remove the near wellbore damage, which is performed by injecting acid into the formation through the wellbore. The injected acid dissolves the rock, by which the permeability nearby the wellbore can be improved. For a carbonate reservoir, the injected acid dissolves some of the minerals and some narrow and long channels, named wormholes, are formed then. These wormholes can bypass the damaged zone and hence improve the productivity of the well. The process for acid dissolving rocks involves complex physicochemical change, including the chemical reactions at the pore scale and the fluid flow at Darcy scale. In this paper, a 3-D reactive flow model with non-Darcy framework is developed based on the two-scale continuum model, and is solved by using the finite volume method. Five types of dissolution patterns, named face dissolution, conical wormhole, wormhole, ramified wormhole, and uniform dissolution, are obtained as the injection velocity increases. The effect of non-Darcy flow on dissolution pattern and breakthrough volume is analyzed. It is found that there is no effect of non-Darcy on dissolution structure and breakthrough volume when the injection velocity is very low. However, when the injection velocity is very high, the generated wormhole has more branches when using the Forchheimer equation than using the Darcy equation. Moreover, the optimal injection velocity is found to be the same whether considering the non-Darcy flow or not.
Fractal analysis of shape factor for matrix-fracture transfer function in fractured reservoirs

As the core function of dual-porosity model in fluids flow simulation of fractured reservoirs, matrix-fracture transfer function is affected by several key parameters, such as shape factor. However, modeling the shape factor based on Euclidean geometry theory is hard to characterize the complexity of pore structures. Microscopic pore structures could be well characterized by fractal geometry theory. In this study, the separation variable method and Bessel function are applied to solve the single-phase fractal pressure diffusion equation, and then the obtained analytical solution is used to deduce one-dimensional, two-dimensional and three-dimensional fractal shape factors. The proposed fractal shape factor can be used to explain the influence of microstructure of matrix on the fluid exchange rate between matrix and fracture, and is verified by numerical simulation. Results of sensitivity analysis indicate that shape factor decreases with tortuosity fractal dimension and characteristic length of matrix, increases with maximum pore diameter of matrix. Furthermore, the proposed fractal shape factor is effective in the condition that tortuosity fractal dimension of matrix is roughly between 1 and 1.25. This study shows that microscopic pore structures have an important effect on fluid transfer between matrix and fracture, which further improves the study on flow characteristics in fractured systems.

Mega sporting events have been hailed for resulting in economic growth, evident in high investments, growth of businesses, and development of infrastructure because of the increased number of investors, tourists, and fans visiting host countries during such events. Even though host countries may experience non-economic benefits, such as a good legacy from the mega sporting events, there are also significant economic benefits realised by host countries. The study intended to assess the anticipated economic impacts of the 2022 FIFA World Cup in Qatar as a developing country. The study engaged in descriptive research design. Primary data was collected from research participants comprising Hotel Managers, Sports managers, Economic consultants, Project managers in the construction industry, and bank managers. Further, the study selected a sample of 50 respondents in data analysis. The researcher adopted inferential statistics to analyse data from the respondents, who were all from Qatar. The results of the study indicated that 2022 FIFA World Cup is likely to raise the employment level, especially for construction workers involved in the construction of stadia, growth of income level expansion of business, especially in hospitality industries are likely to attract many foreign visitors. Also, findings suggest that Qatar will experience an increase in the price of commodities and development of infrastructure. The findings depicted that the 2022 FIFA World Cup in Qatar will result in increased operating costs in the short-term and the long-term. Besides, the study found out that the event will lead to a high level of capital cost and a state of resource deficiency. The study concluded that the 2022 FIFA World Cup in Qatar as a developing country would have significant economic effects on the country. The researcher recommended that Qatar should focus on investing in projects that will help boost income levels for employees, boost business growth, attract more foreigners as tourist and fans, reduce the prices of goods and services as well as accommodation and activities that will reduce the long-term.
Recent advances and future trends in articular cartilage repair
Authors: Goyal Deepak
Published: July 2020

Hyaline cartilage is an absolute necessity for a painless and a fully functional joint. A chondral or an osteochondral injury that doesn’t heal or doesn’t undergo a timely repair, eventually lead to arthritis. Many surgical options have been advocated and practiced in last three decades to treat the chondral and the osteochondral lesions. While some of the techniques are now available with the long term results, many techniques have evolved further to produce better results and lesser complications. Newer technologies have also been developed and they are looking promising. In 2020, it is timely to do a literature review of all the techniques suggested and practiced in last three decades and analyze their current status. It is also prudent to envisage, what can we expect in near future from the recent technologies on cartilage repair. The purpose of this paper is to update about the recent status of the established procedures and to review the future trends in cartilage repair.
History of arthroscopy in India: Origins and evolution

Published: July 2020

The practice of arthroscopy in India had started as early as 1978; and during the same year, the Indian chapter of the International Arthroscopy Association was drafted alongside other countries such as Australia and Brazil. The subspecialty of arthroscopy has been a boon to both; the orthopedic surgeon and the patient. The advent of arthroscopy has enabled the orthopedic surgeon to clearly visualize and delineate the extent of disease, with minimal invasion. Moreover, the patient is benefited with rapid recovery and an early return to activities. The present-day arthroscopic surgeries include diagnostic arthroscopy, ligament reconstruction, cartilage repair, and labral repairs and have undoubtedly evolved into a glamorous subspecialty in orthopedics. However, before the technological advancements, the technique of arthroscopy had modest origins. This review traverses through the history of arthroscopy with special emphasis on the advances of arthroscopy in India.
Recent advances and future trends in hip arthroscopy

Published: July 2020

Hip arthroscopy (HA) is a well-established minimally invasive technique used to treat a wide range of conditions. Technological innovations have expanded the scope of HA and improved its outcomes. Several authors have described post-less arthroscopy to overcome the risk associated with the use of the perineal post for obtaining distraction of the hip joint. Instrument refinement has improved the efficacy of labral repair and reconstruction. Several treatment strategies are available for articular cartilage defects including ACI, MACI, and mosaicplasty, to name a few. Some authors have suggested that ligamentum teres reconstruction is helpful in young active patients with femoroacetabular impingement experiencing subluxation of the hip joint. The incorporation of new technology and patient-specific approaches represents a new way to improve HA outcomes. Virtual reality simulation training is the key to overcoming the steep learning curve associated with HA and to achieve high standards early in a surgeon’s career. Computer-based navigation surgery may be the key to accurately resecting the cam deformity and reducing the rate of revision surgery due to inaccurate resection at the index procedure. Assessment and optimization of the baseline psychological state and effective pre-habilitation may also improve outcome measures. Adequate stratification of the pathology and assessment of baseline patient characteristics influences the long-term outcome following the HA.
Organocatalyzed Birch Reduction Driven by Visible Light

Published: July 2020

The Birch reduction is a powerful synthetic methodology that uses solvated electrons to convert inert arenes to 1,4-cyclohexadienes—valuable intermediates for building molecular complexity. This reaction historically requires dangerous alkali metals and cryogenic liquid ammonia as the solvent, severely limiting application potential and scalability. Here, we introduce benzo[ghi]perylene imides as new organic photoredox catalysts for Birch reductions performed at ambient temperature and driven by visible light. Using low catalyst loadings (<1 mole percent), benzene and other functionalized arenes can be selectively transformed to 1,4-cyclohexadienes in good yields. Mechanistic studies support that this unprecedented visible light induced reactivity is enabled by the ability of the organic photoredox catalyst to harness the energy from two visible light photons to affect a single, high energy chemical transformation, likely proceeding through a solvated electron.
A Natural Orbital Branching Scheme for Time Dependent Density Functional Theory Nonadiabatic Simulations
Authors: Wang Lin-Wang
Published: July 2020

Real time time dependent density functional theory (rt-TDDFT) has now been used to study a wide range of problems, from optical excitation, to charge transfer, to ion collision, to ultrafast phase transition. However, conventional rt-TDDFT Ehrenfest dynamics for nuclear movement lacks a few critical features to describe many problems: the detail balance between state transition, decoherence for the wave function evolution, and stochastic branching of the nuclear trajectory. There are many-body formalisms to describe such nonadiabatic molecular dynamics, especially the ones based on mixed quantum/classical simulations, like the surface hopping and wave function collapsing schemes. However, there are still challenges to implement such many-body formalisms to the rt-TDDFT simulations, especially for large systems where the excited state electronic structure configuration space is large. Here we introduce two new algorithm for nonadiabatic rt-TDDFT simulations: the first is a Boltzmann factor algorithm which introduces decoherence and detailed balance in the carrier dynamics, but uses mean field theory for nuclear trajectory. The second is a natural orbital branching (NOB) formalism, which use time dependent density matrix for electron evolution, and natural orbital to collapse the wave function upon. It provides decoherence, detailed balance and trajectory branching properties. We have tested these methods for a molecule radiolysis decay problem. We found these methods can be used to study such radiolysis problem in which the molecule is broken into many fragments following complex electronic structure transition paths. The computational time of NOB is similar to the original plain rt-TDDFT simulations
