Verification of methodological procedures of local muscle load and ergonomics at the workplace

The submitted project is aimed at verifying the methodological procedures of local muscle load and ergonomics in the workplace using available devices on a representative sample of probands and know-how. For this reason, a scientific team from the BALUO Application Centre at Palacký University in Olomouc was approached, which deals with the issue itself and has very good prerequisites to solve the project thanks to the specialisation of FTK in physiotherapy and compensation activities. a.
Magnetostriction and the influence of harmonics in magnetizing voltage in electrical steel

Electrical steel laminations used in the transformer cores and motors are subject to stresses (σ) introduced during their construction. The magnetostriction as a major source of acoustic noise of the transformer cores has high stress sensitivity and is harmful to the electrical power grid. The higher harmonics of magnetostriction are more important than the fundamental when considering transformer noise. In the past, researchers have mostly focused on the magnetostriction of electrical steel under purely sinusoidal flux density. However, there are some higher harmonics of the voltage in the grid due to nonlinear load, which will induce harmonics in the flux density. It is useful find the relationship between harmonics in flux density and magnetostriction. The influence of harmonics in the magnetic field under zero stress has been studied.[1] The increase of magnetostriction with the percentage of harmonics in the flux density has been found, where the phase of harmonics with respect to the fundamental is the same.[2] The influence of harmonics with a variety of percentage and phase delays in the magnetizing voltage under stress on magnetostricon harmonics, where the amplitude of the flux density keeps constant, has rarely been studied. Moreover, there are few studies about the influence of harmonics in magnetizing voltage on the DC component in the magnetostriction.
PLUG FOR CONCRETE FLOOR PENETRATIONS

A plug includes a conformable element and a structural cover or top plate for plugging a hole in a concrete floor slab. This permits a workman to plug the hole; unplug the hole; and, in some embodiments, fit a pipe through the hole. Moreover, the conformable element may be swapped-out on site, allowing a workman to adjust a diameter and outer surface of the plug to meet on- site conditions.
Coverage-directed stimulus generation using a genetic algorithm

With the evolution of modern verification methodologies, system-level verification using constrained-random stimulus is a high priority, especially in very large communication applications. A key goal to address is providing fast, effective test coverage. In this paper, we propose a novel method to achieve this goal using a genetic algorithm. First, we present background information about coverage-driven verification methodology, as well as the basic concept and process of the genetic algorithm. Next, we discuss the details of the novel method for integrating this algorithm into a practical verification process. Thereafter, we introduce a simple simulation platform coded in C for benchmarking the proposed method, and present results which illustrate a sharp reduction in the times to complete all coverage bins compared to the traditional test coverage method. Finally, we use a peripheral component interconnect express (PCIE) system as a case study to show the effectiveness of the proposed method in a real application.
Two‐Photon Up‐Conversion Photoluminescence Realized through Spatially Extended Gap States in Quasi‐2D Perovskite Films

A new approach to generate a two-photon up-conversion photoluminescence (PL) by directly exciting the gap states with continuous-wave (CW) infrared photoexcitation in solution-processing quasi-2D perovskite films [(PEA)2(MA)4Pb5Br16 with n = 5] is reported. Specifically, a visible PL peaked at 520 nm is observed with the quadratic power dependence by exciting the gap states with CW 980 nm laser excitation, indicating a two-photon up-conversion PL occurring in quasi-2D perovskite films. Decreasing the gap states by reducing the n value leads to a dramatic decrease in the two-photon up-conversion PL signal. This confirms that the gap states are indeed responsible for generating the two-photon up-conversion PL in quasi-2D perovskites. Furthermore, mechanical scratching indicates that the different-n-value nanoplates are essentially uniformly formed in the quasi-2D perovskite films toward generating multi-photon up-conversion light emission. More importantly, the two-photon up-conversion PL is found to be sensitive to an external magnetic field, indicating that the gap states are essentially formed as spatially extended states ready for multi-photon excitation. Polarization-dependent up-conversion PL studies reveal that the gap states experience the orbit–orbit interaction through Coulomb polarization to form spatially extended states toward developing multi-photon up-conversion light emission in quasi-2D perovskites.
Towards an enhanced accident management of the hydrogen/co combustion risk

Combustible gases are one of the few elements that can really challenge the containment integrity. An appropriate management of the associated risk is paramount to avoid the potential release of large amounts of radioactive material to the environment. Surprisingly, the Severe Accident Management Guidelines (SAMGs) have not been updated according to the knowledge gained in the last decade and the database extension resulting from recent and ongoing projects. The AMHYCO project intends to respond to practical questions, such as the right timing and mode for actuation of containment safety systems (i.e., FCVS, sprays, fan coolers) to reduce as much as feasible the threat posed to containment integrity. To do so, all the available tools to enhance the present status (i.e., LP, 3D and CFD codes, together with experimentation and the best use of engineering judgement) are to be applied. Three specific objectives are set:
•            To improve the Severe Accident Management Guidelines (SAMGs) for both in-vessel and ex-vessel phases with respect to combustible gases risk management, using both numerical and experimental results.
•       To investigate experimentally phenomena that are difficult to predict numerically: H2/CO/H2O distribution and combustion and PARs behavior under realistic accidental conditions, taking into account the safety systems interaction.
•        To improve the predictability of the numerical tools - Lumped Parameter (LP), 3D containment and Computational Fluid Dynamic (CFD) codes - used for explosion hazard evaluation inside the reactor containment to gain relevance in supporting SAMGs design and development.
The scope of this project is outlined by the most common reactor technology in the EU: PWRs. The whole project is structured in 7 WPs (coordination included) in which an entire WP is to be devoted to the enhancement of SAMGs. Finally, AMHYCO has received the NUGENIA label and 9 organizations have shown their interest with support letters .
Stent-Save a Life international survey on the practice of primary percutaneous coronary intervention during the COVID-19 pandemic

To assess the impact of the COVID-19 pandemic on admissions of patients with acute coronary syndromes (ACS) and primary percutaneous coronary intervention (PPCI) in countries participating in the Stent-Save a Life (SSL) global initiative.We conducted a multicenter observational survey to collect data on patient admissions for ACS, ST-elevation myocardial infarction (STEMI) and PPCI in participating SSL member countries through a period during the COVID-19 outbreak (March and April 2020) compared with the equivalent period in 2019. Of the 32 member countries of the SSL global initiative, 17 agreed to participate in the survey (three in Africa, five in Asia, six in Europe and three in Latin America). Overall reductions of 27.5% and 20.0% were observed in admissions for ACS and STEMI, respectively. The decrease in PPCI was 26.7%. This trend was observed in all except two countries. In these two, the pandemic peaked later than in the other countries.This survey shows that the COVID-19 outbreak was associated with a significant reduction in hospital admissions for ACS and STEMI as well as a reduction in PPCI, which can be explained by both patient- and system-related factors.Avaliar o impacto da pandemia COVID-19 nas admissões de doentes com síndromes coronárias agudas (SCA) e angioplastia coronária primária (PPCI) em países que participam da iniciativa global Stent-Save a Life (SSL).Realizámos estudo observacional multicêntrico para coletar dados sobre admissões de doentes por ACS, STEMI e PPCI nos países participantes no SSL durante um período do surto COVID-19 (março e abril de 2020) em comparação com o período homólogo de 2019. Dos 32 países membros da iniciativa global SSL, 17 aceitaram participar no estudo (3 de África, 5 da Ásia, 6 da Europa e 3 da América Latina (LATAM)). Observámos uma redução global de 27,5% e 20,0% nos internamentos com SCA e STEMI, respetivamente. A diminuição do PPCI foi de 26,7%. Essa tendência foi observada em todos os países, exceto dois. Nestes dois países, a pandemia atingiu o pico mais tarde do que nos restantes.Este estudo mostra que o surto de COVID-19 foi associado a uma redução significativa de admissões hospitalares por SCA e STEMI, bem como uma redução de PPCI, o que pode ser explicado por fatores relacionados com o doente e com o sistema.
Analysis of artifacts suggests DGGE should not be used for quantitative diversity analysis

PCR-denaturing gradient gel electrophoresis (PCR-DGGE) is widely used in microbial ecology for the analysis of comparative community structure. However, artifacts generated during PCR-DGGE of mixed template communities impede the application of this technique to quantitative analysis of community diversity. The objective of the current study was to employ an artificial bacterial community to document and analyze artifacts associated with multiband signatures and preferential template amplification and to highlight their impacts on the use of this technique for quantitative diversity analysis. Six bacterial species (three Betaproteobacteria, two Alphaproteobacteria, and one Firmicutes) were amplified individually and in combinations with primers targeting the V7/V8 region of the 16S rRNA gene. Two of the six isolates produced multiband profiles demonstrating that band number does not correlate directly with α-diversity. Analysis of the multiple bands from one of these isolates confirmed that both bands had identical sequences which lead to the hypothesis that the multiband pattern resulted from two distinct structural conformations of the same amplicon. In addition, consistent preferential amplification was demonstrated following pairwise amplifications of the six isolates. DGGE and real time PCR analysis identified primer mismatch and PCR inhibition due to 16S rDNA secondary structure as the most probable causes of preferential amplification patterns. Reproducible DGGE community profiles generated in this study confirm that PCR-DGGE provides an excellent high-throughput tool for comparative community structure analysis, but that method-specific artifacts preclude its use for accurate comparative diversity analysis.
Modelling the impact of geochemical reactions on hydrocarbon phase behavior during CO2 gas injection for enhanced oil recovery

Abstract CO2 injection in oil reservoirs offers the dual advantage of increasing oil recovery as well as storage to combat global warming. The injected CO2, however, may react with ions present in the brine as well as the rock. In this research, we present a model that quantifies the impact of these geochemical reactions on the phase behavior of hydrocarbon mixtures. A Gibbs free energy model is proposed that unifies different phase descriptions – the Peng–Robinson Equation of State (PR EOS) description for hydrocarbon phase components, the Pitzer activity coefficient model for aqueous components and an ideal solid phase. In particular, we illustrate the use of this model to determine the impact of geochemical reactions, introduced by the presence of an aqueous phase with ions and a solid calcite phase, on the phase envelope of CO2-nC14H30 mixture with different phase descriptions. The presented Gibbs free energy model is adaptable to different reservoir brines and can be used to assess the maximum impact of geochemical reactions during CO2 injection in different hydrocarbon reservoirs.
LOCKING AND CODING SYSTEM AND CODING DEVICE THEREFOR

The present invention relates to a locking and coding system which comprises a closing unit (1) with an actuator (2), a coding device (3) and a source (4, 9) of pressurised air. The pressurised air used to drive the actuator is generated by human effort, said actuator being a pneumatic one connected via a duct (20) to the source. The coding device (3) includes at least one coding unit (22, 23, 24) with at least one overlapping member (29, 30, 43, 50, 51, 52), said member being capable of movement along a surface having apertures (26<1>, 45, 46, 56) which correspond to apertures (31<1>, 31<p>, 32<1>, 32<p>, 44<1>, 44<p>, 56) in said overlapping member (29, 30, 43, 50, 51, 52) during its displacement. When a correct code combination is selected, a through-canal is then formed that connects the source (4, 9) of pressurised air to the pneumatic actuator (2) of the locking unit (1).
Sustainable cities as organisms, a circular thermodynamics perspective

More than 50% of us now live in cities while world population growth and urbanization continues unabated. There is an urgent need for policies that can address both the challenges and opportunities for sustainable development in urban settings. Within the past two decades, the idea of cities as fractal structures resulting from social and economic processes led to a transition in thinking of cities as machines to cities as organisms. Independently, the concept of ‘sustainable cities’ had emerged earlier, with many successful implementations already underway. I propose to define a sustainable city as one able to feed and power itself as much as possible using land and energy efficiently with the least environmental pollution and impact on climate change, minimizing wastes and recycling and reconverting wastes into resources. Coherent fractal space-time structures are the key to a circular thermodynamics of organisms and sustainable systems that achieves the state of minimum entropy production and dissipation that Ilya Prigogine had proposed as a conjecture. In this article, I explain how the principles of circular thermodynamics can be applied to sustainable cities.
Customer Perception Towards Brand: A Study on â€˜Patanjaliâ€™

The ever changing marketing scenario and heightened competition over the globe has amplified the role of brand at unparalleled level. Every person is a consumer of different brands at the same time. The choice and usage of a particular brand by the consumer over the time is affected by the quality benefits offered by the brand especially when it comes to brand of eatables and cosmetics. Consumer satisfaction is derived when he compares the actual performance of the product with the performance he expected out of the usage. Philip Kotler (2008) observed that satisfaction is a person's feelings of pressure or disappointment resulting from product's perceived performance (outcome) in relation to his or her expectations. If the perceived benefits turned out to be almost same as expected, customer is highly satisfied and that is how the company achieves loyalty of the customer towards the products.
Differential thermosensitivity in mixed syndrome cardiac sodium channel mutants

Cardiac arrhythmias are often associated with mutations in SCN5A the gene that encodes the cardiac paralogue of the voltage-gated sodium channel, NaV 1.5. The NaV 1.5 mutants R1193Q and E1784K give rise to both long QT and Brugada syndromes. Various environmental factors, including temperature, may unmask arrhythmia. We sought to determine whether temperature might be an arrhythmogenic trigger in these two mixed syndrome mutants. Whole-cell patch clamp was used to measure the biophysical properties of NaV 1.5 WT, E1784K and R1193Q mutants. Recordings were performed using Chinese hamster ovary (CHOk1) cells transiently transfected with the NaV 1.5 α subunit (WT, E1784K, or R1193Q), β1 subunit, and eGFP. The channels' voltage-dependent and kinetic properties were measured at three different temperatures: 10ºC, 22ºC, and 34ºC. The E1784K mutant is more thermosensitive than either WT or R1193Q channels. When temperature is elevated from 22°C to 34°C, there is a greater increase in late INa and use-dependent inactivation in E1784K than in WT or R1193Q. However, when temperature is lowered to 10°C, the two mutants show a decrease in channel availability. Action potential modelling using Q10 fit values, extrapolated to physiological and febrile temperatures, show a larger transmural voltage gradient in E1784K compared to R1193Q and WT with hyperthermia. The E1784K mutant is more thermosensitive than WT or R1193Q channels. This enhanced thermosensitivity may be a mechanism for arrhythmogenesis in patients with E1784K sodium channels.
Karyology of the Scorzonera L. (Asteraceae) taxa from Turkey

In this study, the karyotypes of 13 taxa of the tribe Lactuceae growing naturally in Turkey were examined. Of the species of the genus Scorzonera L. (Asteraceae), S. laciniata L. subsp. laciniata, S. cana (C.A.Mey.) Hoffm. var. jacquiniana (W.Koch) Chamb., S. suberosa C.Koch subsp. suberosa, S. mollis M.Bieb. subsp. mollis, S. papposa DC., S. lacera Boiss. & Bal., S. elata Boiss., and S. parviflora Jacq. have a diploid chromosome number of 2n = 14. For S. phaeopappa (Boiss.) Boiss., this number is 2n = 28, and for S. eriophora DC., S. pseudolanata Grossh., S. tomentosa L., and S. kotschyi Boiss., it is 2n = 12. The average chromosome length of the taxa examined was between 1.20 and 7.63 \mum. All of the taxa have median and submedian chromosome pairs in their chromosome morphologies. With the exception of S. parviflora, the chromosome morphologies of the taxa examined are presented here for the first time.
Research project on the cross-border dairy sheep stock, the production techniques and the quality of the products obtained; transfer of the collected data to the sector.

The project aims at gathering more accurate and thorough information about the sheep stock in the Venetian province and in the Slovenian partner area. The dairy sector - and in particular the breeding system, the breeds chosen, the quality of the produced milk and cheese - are going to be monitored in order to better understand the components of the production sector. The first stage is going to detect the areas of production and consumption of pure and mixed ewe’s-milk cheese, linking them with neighbouring and/or similar areas in the Veneto region and in Slovenia. To this end, the breeds that are - and were - part of the stock for the production of these types of cheese, and their connections with the territory are going to be analysed and studied. Equally important is analysing the systems of breeding and feeding, the productive cycle, the chemical, organoleptic and dairy characteristics of milk, the methods of processing, conservation and ripening, as well as the cheese-selling systems, without neglecting the characteristics of intermediate and final users. An accurate identification of products makes it possible to update the national list, possibly taking advantage of the exceptions with regard to health and hygiene. The exceptions that legitimize the traditional practices are defined by decree for each traditional product, taking account of the hygienic standards of production and ensuring that the final product meets the requirements of healthiness and safety. Production traditions will therefore be resumed also by restaurants and farmhouse accommodations.
Transepithelial Iontophoresis Corneal Collagen Cross-linking for Progressive Keratoconus: Initial Clinical Outcomes

To report initial clinical results of transepithelial corneal collagen cross-linking with iontophoresis (I-CXL).Twenty eyes of 20 patients diagnosed as having progressive keratoconus who underwent I-CXL were included in this prospective non-randomized clinical study. Corrected distance visual acuity (CDVA), spherical equivalent and cylinder refraction, various corneal topography and Scheimpflug tomography parameters, aberrometry, anterior segment optical coherence tomography, and endothelial cell count were assessed at baseline and at 1, 3, 6, and 12 months postoperatively.CDVA improved significantly at 3, 6, and 12 months postoperatively (logMAR difference of -0.07 ± 0.01, -0.09 ± 0.03, and -0.12 ± 0.06, respectively; P < .05). Aberrometry remained stable during follow-up and a trend toward improvement was noted. All topographic parameters (including maximum keratometry) were stable during the follow-up, but exhibited a positive non-significant trend toward improvement. Minimum corneal thickness values were stable for up to 12 months postoperatively. None of the patients showed a progression of keratoconus. Endothelial cell counts did not change significantly (P > .05).Preliminary results up to 1 year postoperatively indicate the efficacy of I-CXL in stabilizing the progression of this degenerative disease combined with significant improvement of CDVA. I-CXL, which spares the corneal epithelium, has the potential to become a valid alternative for halting the progression of keratoconus while reducing postoperative patient pain, risk of infection, and treatment time in select patients; however, the relative efficacy of this technique compared to standard epithelium-off techniques remains to be determined.
