Innovative solutions to enhance safe and green environments for ageing well using stakeholder co-design.

Background There is a need to develop innovative solutions to enhance safe and green physical environments, which optimise health, wellbeing and community participation among older adults. In order to develop solutions that meet the needs of a diverse ageing population, an interdisciplinary approach is needed. Our aim was to identify the needs of older people in relation to ageing well in the environment by bringing together knowledge from different stakeholder and interdisciplinary perspectives. Methods An international consortium (Retrofit living For ageing well through Understanding and Redesign of Built environments consortium: ReFURB) was established in April 2018, including ten core members, to (i) explore cutting-edge solutions to safe living for ageing populations and (ii) develop innovative approaches to everyday physical environments, which bring about health benefits. We used a co-design, interdisciplinary framework involving older adults, carers, physiotherapists, geriatricians, engineers, human movement experts, geographers and psychologists from the UK and Australia. This engaged people in a one day workshop that comprised a series of presentations from international speakers on urban design, social connectedness, hazards and injury prevention, and the physical environment. Small group discussions (facilitated by consortium members) followed presentations to consider the opportunities, challenges and barriers encountered with ageing, which included the use of creative engagement activities (LEGO® Serious Play, mind maps, poster gallery walk), to help participants share personal stories and reflect on the issues raised. Thematic coding was used to synthesise the outputs of the small group work. Results Five themes emerged across the workshops, comprising: access and transport; involvement of the whole community; restoration rather than redesign; assistive and digital technology; and intergenerational approaches. These dimensions related to the physical, social and nature-based qualities of everyday environments, as they pertain to ageing well. Conclusions Co-design was a valuable tool that helped understand the perceptions of stakeholders and essential to develop effective interventions and solutions. Participants highlighted several issues affecting people as they age and key environmental considerations to promote wellbeing, activity, and participation. The consortium identified gaps in the existing evidence base and are now planning activities to further develop research ideas in collaboration with our co-design participants.
BIOTELEMETRY OF THE TRIAXIAL BALLISTOCARDIOGRAM AND ELECTROCARDIOGRAM IN A WEIGHTLESS ENVIRONMENT. MONOGR NO. 10.

Abstract : Biotelemetry instrumentation was developed to record the cardiac-originated inertial accelerations of a subject freely floating in the weightless environment realized in a jet aircraft flying a Keplerian trajectory. The weightless state served as an ideal suspension system and allowed unrestricted motion of the subject with six degrees of freedom. The report describes in detail the design and development of the Constraint Platform with attached Biotelemetry Module used to transduce, signal condition, and telemeter the physiological measurements. A similar description is given of the airborne receiving station used to receive, display, and store the telemetered data. Linear and angular acceleration measurements were performed with this equipment and the results represent the first recording of a triaxial inertial acceleration ballistocardiogram. Triaxial electrocardiographic data were simultaneously measured and telemetered to permit correlation of the mechanical and electrical events of the cardiac complex. The linear acceleration patterns were also displayed in loop form and in a three-dimensional arrangement to facilitate interpretation of their spatial relationship. (Author)
Methodological Aspects of the Typology of Regions and Territorial Formations

This paper presents the typology of regions in developed countries. It includes illustrated scientific concepts of describing development of regional territorial systems based on local cores used as the basis for the typology. The article identifies typologies, highlighting reasons behind the attractiveness of individual regions for capital and labour; as well as links among economic operators. Typology methods for European regions are discussed, including typologies associated with transport accessibility, economic specialisation and the functional structure of regions. In most typologies, the basic developmental factors and solutions to practical issues are taken into account. A special role is played by typologies that are associated with economic growth and those that take into consideration a GDP per capita increase; along with the population density factor. Attention is drawn to the use of research on the typology of regions with regards to developmental planning, modelling and strategizing.
DNAP: Dynamic Nuchwezi Architecture Platform - A New Software Extension and Construction Technology

The need to improve or build new software systems to solve new and old business challenges is a persistent challenge inthe software consumer and development industry, yet costly. To minimize these costs, the construction method should be designed with the following qualities in mind; software portability, extensibility, and simplicity. To achieve these qualities, this paper proposes the Dynamic Nuchwezi Architecture Platform (DNAP), which is a new software construction and extension technology. DNAP offers avisual programming paradigm with a capability of generating production-ready business automation software for both mobile and web. It also offers a simple mechanism for the extension of existing softwares using embeddable components. To evaluate and justify DNAP, eight Software Operating Environment (SOE) metrics have been developed and together with the SOE model, are used to contrastDNAP against four alternative software construction technologies namely; Android Platform, . NET Framework, Java SE Platform and Python. The performance evaluation results show that DNAP offers an average of 33% reduction in software construction complexity and an 11% enhancement in language efficiency when compared to alternative technologies.
Electrodeposited Hydroxyapatite/Graphene Oxide/Zirconia Oxide Composite Coatings: Characterization and Antibacterial Activity

The current study aimed to characterize the hydroxyapatite, zirconia, and graphene oxide nanocomposite coatings on titanium substrate by the use of electrophoretic deposition. In the first stage, besides the characterization of the created composite coating, the thickness and uniformity of the created coating were evaluated by the use of Scanning Electron Microscope (SEM). Also, the distribution of the Nano-powder particles was investigated by the elemental analysis. In the second stage, by the use of X-ray diffraction analysis, the position of the materials used in the coating was drawn and investigated. In the third stage, in order to evaluate the coating’s corrosion behavior due to the addition of nanoparticles to the hydroxyapatite and compare it with the non-coated sample, the electrochemical analyses in the form of chemical polarization were investigated and analyzed with drawing the related charts. Finally, in the fourth stage, the antibacterial tests on the Escherichia coli and Staphylococcus bacteria on the coating were conducted and compared to the uncoated alloy samples. The corrosion test results indicated that the use of nano-composite coating leads to the increase in corrosion resistance of the surface. The antibacterial tests results demonstareted that the use of nano-composite coating effectively decreases the bacteria growth on the surface.
Pharmaceutical compositions based on diclofenac

PURPOSE: The pharmaceutical compositions of the diclofenac salts for oral use are generally accompanied by side effects of not inconsiderable consequence and £(2,6-dichloro-anylano)-2-phenyl|-2-acetate(diclofenac) salts are characterized by a particularly unpleasant and bitter taste and cause intense form of irritation in the buccal cavity, especially in the area of the larynx. CONSTITUTION: Novel pharmaceutical compositions for oral use containing diclofenac together with alkali metal carbonates and bicarbonates and particular flavoring substances are entirely palatable and free from any unpleasant taste or other side effect. Inorganic salts such as alkali metal carbonates and bicarbonates are added about 20-80 weight % to that of diclofenac. 1/5-3 times diclofenac of pure flavoring substances can be added.
Smoking and Incidence of Sleep Disorder: a systematic review and meta-analysis of cohort studies

Background Both smoking and sleep disorder are worldwide problems and this study aim to investigate the impact of smoking on the incidence of sleep disorder. Methods PubMed, EMBASE and OVID were searched through March, 2020. Cohort studies reporting the effect of smoking on the incidence of sleep disorder were included. We quantitatively analyzed the basic framework and study characteristics, and then pooled estimate effects with 95% confidence intervals (CIs) of outcomes of each included studies using fixed-effects meta-analyses. Results This systematic review included seven cohort studies involving 17,414 participants. Quantitatively summarized results suggested smoking could increase the incidence of sleep disorder (OR: 1.08, 95%CI: 1.02,1.13). For regular smokers and occasional smokers, significant association between smoking and incidence of sleep disorder was found (regular smoker: OR = 1.07, 95% CI:1.01,1.13; occasional smoker: OR = 1.62, 95% CI:1.15,2.28). As for ex-smokers, the pooled analysis didn’t indicate a positive association (OR = 1.02, 95% CI:0.67,1.54). Subgroup analysis by age, gender ratio and religion showed statistically significant relationship between smoking and incidence of sleep disorder in specific groups. Conclusions Integrated longitudinal observational evidence identified smoking as a significant risk factor of sleep disorder. Considering the limited amount of available researches, more high-quality and prospective cohort studies of large sample sizes are needed to explore details of this association.
Uterine Evacuation before Operative Hysteroscopy in Patients with Active Uterine Bleeding: A randomized controlled trial

Background: Concurrent bleeding or existing clots usually obscure the vision field and decrease the hysteroscopy success rate. Therefore, any efforts made to have a clear view during the hysteroscopy will improve the diagnostic or treatment outcomes. In this study, we examined the effect of preoperative clot evacuation on hysteroscopy and patient outcomes.Methods: In this parallel-group clinical trial conducted from December 2018 to September 2019 at the Oncology Center of Alzahra Teaching Hospital in Tabriz, Iran, 114 patients with uterine bleeding were randomly assigned to receive either clot evacuation before standard operative hysteroscopy or standard hysteroscopy alone. The investigated endpoints were the clarity of vision, the volume of used distension media, duration of the procedure, amount of bleeding, and postoperative complications.Results: All 114 participants completed the study. There were statistically significant differences in the frequency of the clear vision (p<.001), the severity of bleeding (p=.0006), mean serum volume used (p<.001), mean procedure time (p<.001), and the postoperative hematocrit levels (p<.001) between groups, in favor of women with preprocedural intrauterine evacuation. There was no difference in in-hospital stay (p=0.081) and anesthetic complications among the patients (p=0.182). The procedure was successfully performed on all patients of both groups with zero postoperative complications.Conclusion: Removal of clots and other uterine contents before inserting hysteroscope rendered better and faster access to the uterine wall to observe existing abnormalities and reduce the hysteroscopy time. This additional surgical step could take a significant impact on surgical and clinical outcomes.Trial registration: Clinical trial registry name: Iranian Registry of Clinical Trials URL: https://en.irct. ir/trial/33369 The registration number: IRCT20101130005283N13 Date of trial registration: 2018-11-16
Short-Term Outcomes of Low Versus High Inspiratory Oxygen Fraction During Induction of General Anesthesia in Noncardiac Surgery: A Pragmatic Open-Label Randomized Non-Inferiority Trial

Background. High inspiratory oxygen fraction (FIO2) is associated with increased perioperative pulmonary morbidity and postoperative mortality. However, the use of pure oxygen is still currently recommended during the anesthesia induction.Methods, This open-label randomized non-inferiority trial was conducted in two metropolitan hospitals at Southern Taiwan. A total of 302 surgical patients (ASA PC≤III) who received endotracheal general anesthesia (ETGA) were randomized to receive 100% (FIO2 1.0) or 60% (FIO2 0.6) oxygen during induction. The primary endpoint was presence of hypoxemia (SpO2≤92%) during the induction of anesthesia. The secondary endpoint was the development of major complications immediately and within 3 days after surgery.Results. A total of 5 patients in the FIO2 0.6 group developed hypoxemia during induction (3.9% vs 0% for FIO2 0.6 vs FIO2 1.0, respectively; P=0.167 for non-inferiority), suggesting that FIO2 0.6 was inferior than FIO2 1.0 for anesthesia induction. The mean lowest SpO2 during induction was also significantly lower in FIO2 0.6 group. Four patients reached the primary endpoint had increased body mass indexes (BMI>30 kg/m2). However, the overall incidence of desaturation developed after removal of endotracheal tube was higher in FIO2 1.0 group (1.4% vs 5.8%, FIO2 0.6 vs FIO2 1.0; odd ratio 0.22, 95% confidence interval 0.05-1.05; P=0.064). Conclusions. High fractions of oxygen should be used for oxygenation during induction of ETGA in general population, especially in the obese patients. However, the supplement of high FIO2 during induction was associated with increased hypoxemic events after removal of endotracheal tube that might have a more significant impact on perioperative care.
Leveraging Big Data to Advance Gender Equality

Gender equality and the empowerment of women and girls, one of the Sustainable Development Goals, is a highly complex and challenging undertaking. We must address multiple issues— discrimination, violence, education, employment, economic resources, and technology—and work across economic sectors, from agriculture to financial services. Achieving gender equality will require significant amounts of accurate data about the situations and struggles of women and girls. Globally, however, there is a major gap in data that is disaggregated by sex, and this gap often renders women’s societal, cultural, and economic contributions and obstacles practically invisible. It can also exacerbate existing gender divides, feeding and reinforcing biases in social programs, access to financial and other services, economic opportunities
Interface engineering using a perovskite derivative phase for efficient and stable CsPbBr3 solar cells

Inorganic perovskite materials have great potential for application in optoelectronic devices, especially solar cells, due to their outstanding photoelectric properties and high stability. In this work, we demonstrated CsPbBr3 inorganic perovskite solar cells (PSCs) composed of a derivative-phase CsPb2Br5 for the first time by precisely controlling the film thickness of precursor materials. The presence of CsPb2Br5 at the interface of CsPbBr3 crystals can increase the grain size of the inorganic perovskite and effectively passivate grain defects and the electron transport layer. The derivative phase will lower the energy barrier and reduce the carrier recombination in the active layer. Remarkably, this self-passivation results in a respectable power conversion efficiency (PCE) of 8.34% with a CsBr : PbBr2 ratio of 1 : 1.1. Besides, the device exhibits a superior stability for more than 1000 h without any degradation. Insights into the derivative phase formation and self-passivation mechanisms are demonstrated, providing a novel approach to improve the performance of perovskite solar cells.
Structure and Dynamics using NMR Spectroscopy

NMR spectroscopy is one of the few analytical methods that enable the determination of structure as well as dynamics of a molecule at atomic resolution. In the thesis presented here, on the hand methods for the quantification of so far difficult accessible NMR parameters have been developed, which allow an analysis in the above discussed manner. On the other hand, already established procedures have been used to investigate the structure and dynamics of the protein receptor BMPR-IA. For this receptor a disorder-order-transition could be proven upon binding with its natural ligand.
The rise of two‐dimensional van der Waals ferroelectrics

Recent research on ferroelectrics based on two‐dimensional (2D) materials may lead to a technological revolution, offering much higher density for integration as well as a better combination of semiconductor properties and non‐volatile memories at the nanoscale compared with traditional ferroelectrics. In addition, ferroelectricity can be much more robust than ferromagnetism in 2D. In this study, we review the studies on 2D ferroelectricity starting from 2013, which are mainly first‐principles predictions, including functionalization‐induced 2D ferroelectricity in prevalent non‐polar 2D materials as well as 2D intrinsic ferroelectricity, which are either in‐plane or vertical. Although the number of reports on 2D ferroelectricity is still small compared to the large amount of research on 2D ferromagnetism, the potential of these materials to unravel new science and technology has stimulated considerable interest in 2D ferroelectricity, making it a fast developing field. It is interesting to note that 2D ferroelectricity was experimentally realized a year before 2D ferromagnetism, and the large difference in the Curie temperatures of these materials has further demonstrated that 2D ferroelectricity could be much more robust than 2D ferromagnetism.
Single Crystal Growth, Structure, and Electronic Properties of Metallic Delafossite PdRhO2

We report growth of single crystals of the nonmagnetic metallic delafossite PdRhO2, comparing the results from three different methods. Complete crystallographic data were obtained from single crystal X-ray diffraction, and electronic structure calculations were made using the refined structural parameters. Focused-ion beam microstructuring was used to prepare a sample for measurements of the in- and out-of-plane electrical resistivity, and the large observed anisotropy is qualitatively consistent with the cylindrical Fermi surface predicted by the calculations.
The Adoption of e-business Technologies and Processes in Nigerian Small Business Enterprises

Small businesses are often considered important to a nation’s economy. In Nigeria, the small business sector contributes about 48% to the GDP, and there is an increasing effort to support the small business sector as a way of combatting societal ills. Within the last decade, there has been a global increase in the use of e-business by both large and small companies. Today, it is generally acknowledged that e-business provides a range of opportunities for small businesses to operate and compete effectively; however, in developing countries such as Nigeria, there is very limited research on e-business adoption in the small business sector. This thesis examines the adoption of e-business technologies and processes in Nigerian small businesses. Using an inductive approach, informed by a case study strategy, a longitudinal study of six small businesses in Lagos, Nigeria was conducted. Data was collected using interviews and questionnaires, and both thematic analysis and framework analysis were utilised to analyse the cases. Research results indicate that small businesses in Nigeria are utilising e-business systems. Key issues impacting upon e-business adoption and eight critical influencing factors that affect adoption were identified. Based on the case study findings, a framework for the development and implementation of e-business strategy in the Nigerian small business sector was developed and validated. This framework will be of value to small business owners involved in e-business operations, and also provides a basis for follow-up research in developing world countries.
Influence of Reynolds number consideration for aerodynamic characteristics of airfoil on the blade design of small horizontal axis wind turbine

ABSTRACT Airfoil’s aerodynamic characteristics are vital for the design and performance evaluation of wind turbine rotor blades through blade element momentum theory. Generally, the airfoil’s aerodynamic characteristics are evaluated at an approximated fixed Reynolds number. However, during a typical operation of a wind turbine, the Reynolds number varies along the length of the blade as well as with wind speed. Since airfoil’s aerodynamic characteristics are dependent on Reynolds number, inadequate consideration of Reynolds number in blade element momentum theory may result in discrepancy in an optimum design and performance evaluation. In the present work, the influence of inadequate consideration of Reynolds number on design and performance evaluation of a small horizontal axis wind turbine blade is studied. For the study, a wind turbine blade design with various design considerations, including a range of design tip speed ratio (5, 6, 7, and 8) and a range of inadequately approximated fixed (i.e., 0.5, 0.75, 1.00, and 1.25 million) and operational Reynolds number for aerodynamic characteristics of the airfoil, is considered. The study suggests that inadequate fixed Reynolds number consideration for blade design and performance evaluation can result in blade solidity as high as 17.1% with respect to blade design considering operational Reynolds number consideration and discrepancy in power coefficient prediction as high as 3.6% with fixed Reynolds number consideration for aerodynamic characteristics of the airfoil.
Synthesis、Structure and Catalytic Activity of TiO2/ La2Zr2O7 Nanocomposites

TiO2/La2Zr2O7 composites were fabricated by sol-gel method. The composites were characterized by X-ray powder diffraction (XRD), Raman spectrum, scanning electron microscopy (SEM), energy dispersive X-ray spectrometer (EDS) and Brunauer-Emmett-Teller (BET) nitrogen adsorption. The results showed that TiO2 was uniformly coated on the surface of La2Zr2O7 powders. The BET surface area of TiO2/La2Zr2O7 composites was 26.78 m2/g, which was larger than that of La2Zr2O7. Also, the photodegradation of methyl orange was used to evaluate its photocatalytic property. It was found that TiO2/La2Zr2O7 composites showed good photocatalytic activity and the decomposition of methyl orange had basically completed within 30 min.
