Lower Amounts of Daily and Prolonged Sitting Do Not Lower Free-Living Continuously Monitored Glucose Concentrations in Overweight and Obese Adults: A Randomised Crossover Study

This study compared the short-term continuously monitored glucose responses between higher and lower amounts of prolonged sitting in overweight and obese adults under free-living conditions. In a randomised crossover design, 12 participants (age 48 ± 10 years, body mass index 33.3 ± 5.5 kg/m2) completed two four-day experimental regimens while wearing a continuous glucose monitor, as follows: (1) uninterrupted sitting (participants were instructed to sit for ≥10 h/day and accrue ≥7, 1 h sitting bouts each day), and (2) interrupted sitting (participants were instructed to interrupt sitting every 30 min during ten of their waking hours with 6–10 min of activity accrued in each hour). Linear mixed models compared outcomes between regimens. None of the continuously monitored glucose variables differed between regimens, e.g., 24 h net incremental area under the glucose curve was 5.9 [95% CI: −1.4, 13.1] and 5.6 [95% CI: −1.7, 12.8] mmol/L∙24 h, respectively (p = 0.47). Daily sitting (−58 min/day, p = 0.001) and sitting bouts lasting ≥30 min (−99 min/day, p < 0.001) were significantly lower and stepping time significantly higher (+40 min/day, p < 0.001) in the interrupted sitting than the uninterrupted sitting regimen. In conclusion, lower amounts of daily and prolonged sitting did not improve free-living continuously measured glucose among overweight and obese adults.
Highly Efficient Visible Light Active Doped ZnO Photocatalysts for the Treatment of Wastewater Contaminated with Dyes and Pathogens of Emerging Concern

Water is obligatory for sustaining life on Earth. About 71% of the Earth’s surface is covered in water. However, only one percent of the total water is drinkable. The presence of contaminants in wastewater, surface water, groundwater, and drinking water is a serious threat to human and environmental health. Their toxic effects and resistance towards conventional water treatment methods have compelled the scientific community to search for an environmentally friendly method that could efficiently degrade toxic contaminants. In this regard, visible light active photocatalysts have proved to be efficient in eliminating a wide variety of water toxins. A plethora of research activities have been carried out and significant amounts of funds are spent on the monitoring and removal of water contaminants, but relatively little attention has been paid to the degradation of persistent water pollutants. In this regard, nanoparticles of doped ZnO are preferred options owing to their low recombination rate and excellent photocatalytic and antimicrobial activity under irradiation of solar light. The current article presents the roles of these nanomaterials for wastewater treatment from pollutants of emerging concern.
Adaptive Gemischregelung eines Ottomotors

Im Rahmen dieses Aufsatzes wird ein adaptiver Regler für die Kompensation der stark betriebspunktabhängigen Gemischbildungsdynamik in einem Ottomotor erarbeitet. Der Regler ist nach dem Prinzip des indirekten Modellvergleichsverfahrens entworfen. Bei diesem Verfahren werden die Prozeßparameter explizit identifiziert und die Reglerparameter indirekt als Funktion der Prozeßparameter berechnet. Ein erweitertes Kaiman-Filter erweist sich als zweckmäßiges Mittel für die Parameteridentifikation. In einer Reihe von praktischen Versuchen an einem 4-Zylinder 1.8 Liter BMW Motor auf einem dynamischen Prüfstand wird die Tauglichkeit des vorgestellten Regelungsprinzips bestätigt.
Violence Against Politicians, Negative Campaigning, and Public Opinion: Evidence From Poland

It is commonly viewed that violence against politicians increases support for the victim’s party. We revisit this conjecture drawing on evidence from an assassination of an opposition politician in Poland. First, we analyze engagement with Twitter content posted by opposition and government politicians using a difference-in-differences framework. Second, we use a public opinion survey collected in the days around the attack and compare party preferences of respondents interviewed just before and respondents interviewed just after the attack. Our results reveal decreased support for the victim’s (opposition) party relative to support for the government. To explain this finding, we show that the opposition antagonized the public by engaging in negative campaigning against the government over their politician’s assassination. Content analysis of tweets and news media confirms that citizens punished the opposition for their negative campaigning after the violence. Tentative evidence suggests that these effects could have had long-run political consequences.
Idiopathic granulomatous mastitis: diagnostic dilemma

We report a case of Idiopathic granulomatous mastitis in a 21 years old female who came to our hospital with complaints of painful lump in her left breast because the results of initial excision of fibroadenoma, when re-exploration was done to rule out any foreign body – excision biopsy was done. However, the final histopathological diagnosis was granulomatous mastitis with suture granuloma, no evidence of malignancy. A review of literature revealed that idiopathic granulomatous mastitis has a tendency to affect young women. Clinical diagnosis and imaging has often been difficult. Complete resection or corticosteroid therapy can be recommended as appropriate treatment. Since recurrence rate is as high as 50%, long term follow up is indicated in such patients.

Age and gender based study of urine microscopy in children and adolescents: a retrospective study

Background: Urinary tract infection (UTI) is a common reason for accessing health care services in all age groups. Women are more susceptible to UTI across age groups. Among males, the prevalence decreases in adolescence. Socio-economic and behavioural factors may play a significant role in the higher prevalence of UTI among adolescent girls. A study on UTI among children and adolescents will give a better insight in to the gravity of the problem and suggest appropriate interventions. Aim of the current study was to investigate the prevalence of urinary tract infection in males and females in the age group 0 to 20 based on the urine routine examination.Methods: This retrospective study included patients who had urine routine examination (URE) done based on clinical symptoms, during the period from January to December 2018 in a tertiary care teaching hospital. Data was obtained from the laboratory records and medical records department.Results: 1574 (3.43%) out of 45896 patients had a URE. This included 716 males (46%) and 858 females (54%). Among those with positive URE results, females were more affected than their male counterparts and this was statistically significant (male 21.8%, female 78.2%, p< 0.0001). As age advances, the prevalence decreases in males.Conclusions: Urinary tract infection is more prevalent in females across the pre- adolescent and adolescent age group. It decreases with age in males. Understanding the factors responsible for the persistent higher prevalence in females may decrease the prevalence of urinary infection in adolescent females.
Exploring Innovation Ecosystem of Incumbents in the Face of Technological Discontinuities: Automobile Firms

In recent years, the innovation ecosystem concept has received much attention in the strategy and innovation fields to address radical or discontinuous innovation. This study aims to explore the innovation ecosystem construct of incumbents in the face of technological discontinuities, focusing on the ecosystem actors (that is, incumbents, component providers, and complementors) and their activities for sustainable value creation. First, we conducted a literature review of 34 highly cited and relevant research documents discussing the innovation ecosystem concept to extract key phrases for the innovation ecosystem’s research framework. Then, through the lens of dynamic capabilities, the five core capabilities of incumbent focal firms—collaboration and networking, opportunity sensing, entrepreneurial orientation, knowledge management, and strategic flexibility—are derived as key elements of the research framework. In addition, the following case study conducted by the content analysis of two leading automobile incumbents, Volkswagen and Toyota, supports and concretizes the established research framework. We conclude that as the value chain in the industry is open to diverse emerging experts holding critical technologies in the era of discontinuous innovation, the ecosystem actors are extensively linked beyond existing industry boundaries. Next, incumbents’ proposed five core capabilities are essential for their successful navigation of the complex innovation ecosystem. Finally, the case study also indicates that the traditional automobile giants in the existing ecosystem are heading toward sustainable value creation via technology internalization and dominant platform building to transform themselves into leaders of a new innovation ecosystem in the era of Connected, Autonomous, Shared and Services, and Electric (C.A.S.E.) innovation in the automobile industry.
Entwurf und Umsetzung eines rekonfigurierbaren Schaltmatrix-Satelliten-Experiments zum Nachweis der Raumfahrttauglichkeit keramischer Mikrowellenschaltungstechnologie

﻿Information and telecommunications technology is one of the driving forces of technical progress and has significantly advanced development and innovation in the last century affecting all fields of society. Especially the supply of remote locations with communication infrastructure, broadcasting services, etc. benefits from satellite based systems. In order to utilise novel technologies in future aerospace applications, all components and technologies have to prove their compliance for space flight in a time and cost-intensive process. The main requirements of typical geostationary satellites are a life expectancies of 15 years and more, reliability and withstand the harsh environment in terms of ambient atmosphere, radiation, and permanent temperature cycles.The low temperature co-fired ceramics technology (LTCC) enables three-dimensional integration of passive structures, and thereby compact modules with high functional density, creating a promising foundation for space applications. In addition, the LTCC-technology allows for hermetic sealing of modules to incorporate bare dies. The manufacturing process causes a variation of metal structure geometries. Taking this variation during the design phase into account as well as the knowledge of exact material properties forms the essential requirement to achieve high yield and good agreement between simulation and measurement. As part of this thesis, the design, optimisation and qualification processes of the switch matrix experiment are discussed. The manufactured models are presented and results of environmental tests are analysed. Based on the outcome, the experiment and the assembly and integration technology are iteratively optimised and results of mechanical stress tests are validated with numerical models. The switch matrix experiment was integrated into the TET-1 (Technology Experiment Carrier) satellite as part of the KERAMIS payload. The one year on-orbit verification mission started on July 22, 2012 from Baikonur, Kazakhstan and thereby the functional demonstration. Based on available data no degradation was observed.Furthermore, different concepts for the modular utilisation of the 4 x 4 switch matrix to create more complex systems are presented. The effect of single switch errors as well as extensions of electrical functionality by exploitation of fast switching are discussed.
A clash of competing necessities: water adequacy and electric reliability in China, India, France, and Texas

This report describes the application of a new mixed-integer linear programming model of the power sector that accounts for water used for thermal cooling. The model is used to explore a series of scenarios for each of four case studies—the North Grid of China, India, France, and the state of Texas in the United States. For each case study we developed a baseline projection, then modeled a number of scenarios, including limits on water availability, reduced power demand from end-use energy efficiency, expansion of renewable energy, and carbon caps. We provide model output, including water withdrawals and consumption; power generation fuel mix; carbon dioxide emissions; and total system, fixed, and variable costs.
Reducing the Gap between Mental Models of Truck Drivers and Adaptive User Interfaces in Commercial Vehicles

Whether or not a product matches the user’s mental model and therefore his understanding of how it works influences the perceived usability. Therefore, it is beneficial if an interface is based on the user’s initial mental model, hence it works just as expected. If it contradicts preexisting models, operating errors and frustrated users are to be expected. This work proposes a method to increase the probability of correspondence between a developed product and the user’s mental model by addressing a common source of error in the product development process: Product designers assuming their own mental model matches the user’s. The process was demonstrated using the example of an adaptive user interface for commercial vehicles. A questionnaire was used to identify the underlying dimensions of the user group’s mental model of adaptive user interfaces. By conducting two expert workshops and a user survey with 75 truck drivers, a questionnaire consisting of 37 items and four dimensions was constructed. Thereby, the initial mental model of truck drivers regarding an adaptive user interface for commercial vehicles was determined.
Comparative Analysis of Heat Resistance of Ornamental Urban Plants in Kyiv

Urban plants play a significant role in shaping the microclimate of the modern city, in addition to the recreational and aesthetic functions. Climate change and sharp changes in temperature affect the plant growth and development, so the question of studying the adaptive potential of the plant range in cities to temperature variability is relevant and important. Researchers and scientists around the world are studying the impact of biotic and abiotic factors on plants, but the variability of the plant organisms in the urban ecosystem is still unexplored. The data from the analysis of the frequency of occurrence plants in Kyiv green spaces show that Tilia cordata Mill. , Aesculus hippocastanum L. , Spiraea×vanhouttei (Briot) Zabel. and Carpinus betulus L. are most represented among the researched species. The article presents the results of the assessment of heat resistance by using the method of Matskov (1976) of 13 ornamental woody and shrubby species. Besides, the plants were separated into groups of tolerance to high temperatures. It was established that the T. cordata plants are characterized by the highest indicators of heat tolerance and they can be recommended for the creation of open landscapes. The A. hippocastanum, Catalpa bignonioides Walt. , S. vanhouttei and Forsythia europaea Degen & Bald. plants are characterized by ‘moderate tolerance’ indicators to high temperature stress, therefore they can be recommended for the creation of semi-open/open landscape types. Consequently, for the formation of semi-open landscapes, using the species Platanus occidentalis L. , Quercus robur L. , Q. rubra, Syringa vulgaris L. , Berberis thunbergii DC. and Ligustrum vulgare L. which were assessed as ‘moderately sensitive’, is recommended. The leaves of the Carpinus betulus L. and Ribes aureum Pursh. plants were most vulnerable to high temperature stress; therefore, the species are recommended for the formation of closed landscape types. Despite the comparative classification of ornamental plants in terms of heat-resistance, many issues remain unstudied and need to be clarified in terms of ecology, physiology, biochemistry and phytopathology for the plants of urban green spaces.

Hybrid Organic–Inorganic Membranes for Photocatalytic Water Remediation

Mismanagement, pollution and excessive use have depleted the world’s water resources, producing a shortage that in some territories is extreme. In this context, the need for potable water prompts the development of new and more efficient wastewater treatment systems to overcome shortages by recovering and reusing contaminated water. Among the water treatment methods, membrane technology is considered one of the most promising. Besides, photocatalytic degradation has become an attractive and efficient technology for water and wastewater treatment. However, the use of unsupported catalysts has as its main impediment their separation from the water once treated. With this, providing the membranes with this photocatalyzed degradation capacity can improve the application of photocatalysts, since in many cases their application improves their recovery and reuse. This review describes the general photocatalytic processes of the main inorganic nanoparticles used as fillers in hybrid polymeric membranes. In addition, the most recent hybrid organic–inorganic membranes are reviewed. Finally, the membranes formed by metal–organic frameworks that can be considered one of the newest and most versatile developments are described.
Functional outcomes in acute lateral ankle ligament repair using suture tape augmentation

Introduction: Acute lateral ankle injuries are commonly managed conservatively but when repair is done in grade III injuries in the professional athletic population it is repaired using the Broström surgical procedure. Augmentation of this procedure using suture tape has been reported to improve ankle stability and physical patient outcomes. Method: This is a retrospective study of 30 patients with grade II-III anterior talofibular ligament instability, treated with augmented Broström-Gould suture tape procedure. The patients were followed up a minimum of 14.4 months post-surgery using AOFAS and RAND 36-item Short Form scores. We also evaluated ability and time to return to previous level of activity or sport following surgery and rehabilitation. Results: Overall patients showed excellent results, with an average AOFAS score of 92.7. According to the SF-36 scale patients perceived low levels of pain (80.6) and good physical functioning (88.3), with 86.7% of patients in the study being able to return to their previous level of activity or sport on average 10.94 weeks post surgery. Conclusion: Augmented Broström with suture tape showed excellent AOFAS and favourable RAND SF-36 outcomes in the short term with a good indication of functional outcomes in patients’ ability to return to previous levels of activity or sport.
Removal of heavy metals from aqueous solutions by modified waste silk

In order to reuse the waste fabric and develop a novel textile-based adsorbent for heavy metal removal, the waste silk fabric was modified by tannic acid (TA) and the prepared adsorbents were characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) analysis. The removal of Cd(II), Cu(II), and Ni(II) ions from aqueous solutions was investigated using the modified silk fabric (TA-SF) under various conditions and the adsorption behavior of heavy metal ions was compared with the original silk fabric. The results showed that the maximum metal adsorption amounts reached 100% in 10 min. The adsorption isotherm models were demonstrated using Langmuir, Freundlich, and Temkin isotherm models, and the adsorption of TA-SF to Cd(II), Cu(II), and Ni(II) were well fitted with Langmuir isotherm than Freundlich and Temkin isotherm model. Moreover, the adsorption kinetics was well fitted with to the pseudo-first-order and pseudo-second-order kinetic models, and adsorption kinetics indicated that the former model was better suited than the latter. For 60 mg/L initial concentrations of Cd(II), Cu(II), and Ni(II) at pH 9.0, the adsorbents' maximum adsorption capacity was 8.03 mg g−1, 7.42 mg g−1, and 7.47 mg g−1, respectively. Within 5 min, the absorbed metal ions on TA-SF could mostly be desorbed. Moreover, TA-SF can adsorb heavy metal ions from dyeing aqueous solution, showing its capability of simultaneous removal of heavy metal and waste dyes. The results suggest that the lower-cost TA-SF could be an effective adsorbent for removing heavy metals from industrial wastewater.
