Investigation of compositional analysis and physical properties for Ni-Cr-Nb alloys using laser-induced breakdown spectroscopy
Authors: Salloom Hussein , Hamad Tagreed
Published: November 2021

In this work, laser-induced breakdown spectroscopy (LIBS) analysis is optimized for direct estimation of elemental composition, thermal conductivity and hardness for Ni-Cr-Nb alloys. These alloys were chosen with a variable elemental content of niobium and chromium. The influence of laser energy and shot numbers on measuring line intensity was investigated. Based on the ratio between two spectral lines, calibration curves were formed to estimate the element concentration and LIBS results were confirmed with related energy-dispersive X-ray spectroscopy (EDS) data. Hardness and thermal conductivity estimation using LIBS were done by measuring the ratio between two spectral lines, plasma excitation temperature and electron density for different samples. Semi-empirical formulas correlated hardness and thermal conductivity with plasma temperature were established.

La historia de la arquitectura de Lima se ha escrito en muchos textos. Actualmente se cuentan hasta seis historias. En cada una se ha tratado de ver la arquitectura desde un panorama diferente, pero los une algo en común: son las historias de los edificios y de sus autores, ingenieros, ingenieros-arquitectos o arquitectos. La historia que se presenta a continuación trata sobre la arquitectura de Lima a través de sus espacios interiores y cómo sus autores los han configurado. A partir de la selección de edificios emblemáticos construidos en Lima en los últimos 200 años, se muestra su evolución arquitectónica. Y a partir de una metodología diferente, el presente trabajo busca enlazar esas historias construidas a lo largo del siglo XX con el fin de encontrar, a pesar de sus diferencias o discrepancias, valores comunes. De ese modo, el estudio ha identificado un signo distintivo entre sus formas y configuraciones. Esto sustentaría que esas historias sobre la arquitectura de Lima contienen percepción.

Internet court on solving online consumer contract disputes: Case of China
Authors: Sang J.
Published: November 2021

The COVID-19 pandemic has deeply influenced people’s way of life. The need to comply with various social restrictions has posed new and previously unknown challenges to humanity. Internet here plays a significant role in helping to maintain people’s life as usual. As online behavior increases, many disputes arise therefrom grow simultaneously. It is proposed that international online disputes would be solved effectively if Internet technologies were referred to and adopted. Therefore, online litigation, a judicial method specially established to solve online disputes, provides an ideal alternative to the traditional litigation process in this regard. Such litigation can be operated through Internet courts (or cyber courts). Today the palm in their establishment belongs to China that has successfully introduce the world’s first three, and only, Internet courts. Thus, the Chinese experience has been chosen as the primary empirical support of the study on Internet courts. In this essay, a detailed review of the online litigation process will be analyzed using the example of the adopted rules and regulations for resolving disputes, as well as the judgements handed down by the Hangzhou Internet Court, the world’s first cyber court successfully resolving multiple online disputes over four years. The essay firstly reviews the current rules and procedures of Hangzhou Internet court; this would serve for a better understanding of how the world’s first Internet court is operated. After that, the essay discusses in what circumstances foreign courts can recognize and enforce Internet courts’ judgments. The essay ends up with giving personal recommendations on the future development of Internet courts to solve online consumer contract disputes.
No Detectable Kilonova Counterpart is Expected for O3 Neutron Star–Black Hole Candidates

Published: November 2021

We analyze the tidal disruption probability of potential neutron star–black hole (NSBH) merger gravitational-wave (GW) events, including GW190426_152155, GW190814, GW200105_162426, and GW200115_042309, detected during the third observing run of the LIGO/Virgo Collaboration and the detectability of kilonova emission in connection with these events. The posterior distributions of GW190814 and GW200105_162426 show that they must be plunging events, and hence no kilonova signal is expected from these events. With the stiffest NS equation of state allowed by the constraint of GW170817 taken into account, the probability that GW190426_152155 and GW200115_042309 can make tidal disruption is ∼24% and ∼3%, respectively. However, the predicted kilonova brightness is too faint to be detected for present follow-up search campaigns, which explains the lack of electromagnetic (EM) counterpart detection after triggers of these GW events. Based on the best-constrained population synthesis simulation results, we find that disrupted events account for only ≲20% of cosmological NSBH mergers, since most of the primary BHs could have low spins. The associated kilonovae for those disrupted events will still be difficult for LSST to discover after GW triggers in the future because of their low brightness and larger distances. For future GW-triggered multimessenger observations, potential short-duration gamma-ray bursts and afterglows are more probable EM counterparts of NSBH GW events.

Massive black holes at the centers of galaxies can launch powerful wide-angle winds that, if sustained over time, can unbind the gas from the stellar bulges of galaxies. These winds may be responsible for the observed scaling relation between the masses of the central black holes and the velocity dispersion of stars in galactic bulges. Propagating through the galaxy, the wind should interact with the interstellar medium creating a strong shock, similar to those observed in supernovae explosions, which is able to accelerate charged particles to high energies. In this work we use data from the Fermi Large Area Telescope to search for the γ-ray emission from galaxies with an ultrafast outflow (UFO): a fast (v ∼ 0.1 c), highly ionized outflow, detected in absorption at hard X-rays in several nearby active galactic nuclei (AGN). Adopting a sensitive stacking analysis we are able to detect the average γ-ray emission from these galaxies and exclude that it is due to processes other than UFOs. Moreover, our analysis shows that the γ-ray luminosity scales with the AGN bolometric luminosity and that these outflows transfer ∼0.04% of their mechanical power to γ-rays. Interpreting the observed γ-ray emission as produced by cosmic rays (CRs) accelerated at the shock front, we find that the γ-ray emission may attest to the onset of the wind–host interaction and that these outflows can energize charged particles up to the transition region between galactic and extragalactic CRs.

Published: November 2021

When gravitational waves pass near massive astrophysical objects, they can be gravitationally lensed. The lensing can split them into multiple wave fronts, magnify them, or imprint beating patterns on the waves. Here we focus on the multiple images produced by strong lensing. In particular, we investigate strong lensing forecasts, the rate of lensing, and the role of lensing statistics in strong lensing searches. Overall, we find a reasonable rate of lensed detections for double, triple, and quadruple images at the LIGO–Virgo–KAGRA design sensitivity. We also report the rates for A+ and LIGO Voyager and briefly comment on potential improvements due to the inclusion of subthreshold triggers. We find that most galaxy-lensed events originate from redshifts z ∼ 1–4 and report the expected distribution of lensing parameters for the observed events. Besides forecasts, we investigate the role of lensing forecasts in strong lensing searches, which explore repeated event pairs. One problem associated with the searches is the rising number of event pairs, which leads to a rapidly increasing false alarm probability. We show how knowledge of the expected galaxy-lensing time delays in our searches allow us to tackle this problem. Once the time delays are included, the false alarm probability increases linearly (similar to nonlensed searches) instead of quadratically with time, significantly improving the search. For galaxy cluster lenses, the improvement is less significant. The main uncertainty associated with these forecasts are the merger-rate density estimates at high redshift, which may be better resolved in the future.

Published: November 2021

Glycolonitrile (HOCH2CN) is an attractive interstellar prebiotic molecule. Glycolonitrile is considered not only as a possible precursor for glycine but also as a key intermediate for adenine formation. Recently, HOCH2CN was detected toward IRAS 16293−2422 B with the Atacama Large Millimeter/submillimeter Array (ALMA). In this study we perform a comprehensive modeling study on HOCH2CN chemistry under the physical conditions of IRAS 16293−2422 B’s cold envelope and hot corino evolutions using the astrochemical code NAUTILUS and the updated gas-grain chemical network. Our studies not only give the main reactions and the favorable physical conditions for the formation of HOCH2CN but also uncover that the observed glycolonitrile in the cold envelope originates from the gradual accumulation of the gas-phase molecules during the ambient cloud, freefall collapse, and warm-up phases of the cold envelope evolution, and in the hot corino it mainly comes from the accumulated ices during the hot corino evolution. Using the updated chemical network, we also conduct chemical simulations under the physical conditions of Sagittarius (Sgr) B2(N) evolution. The simulation results show that varying the cosmic-ray ionization rate is needed to best reproduce the observational upper limits of HOCH2CN and the observed abundances of CNCHO and CH2CNH toward Sgr B2(N). Moreover, we predict that HOCHCNH, OCH2CN, HOCHCN, HOCCNH, OCCNH, and OCCN have high abundances and may be detectable toward IRAS 16293−2422 B and Sgr B2(N).
Fast Scalar Quadratic Maximum Likelihood Estimators for the CMB B-mode Power Spectrum

Published: November 2021

Constructing a fast and efficient estimator for the B-mode power spectrum of the cosmic microwave background (CMB) is of critical importance for CMB science. For a general CMB survey, the Quadratic Maximum Likelihood (QML) estimator for CMB polarization has been proved to be the optimal estimator with minimal uncertainties, but it is computationally very expensive. In this article, we propose two new QML methods for B-mode power spectrum estimation. We use the Smith–Zaldarriaga approach to prepare the pure B-mode map and the E-mode recycling method to obtain a leakage free B-mode map. We then use the scalar QML estimator to analyze the scalar pure B map (QML-SZ) or B-mode map (QML-TC). The QML-SZ and QML-TC estimators have similar error bars as the standard QML estimators but their computational cost is nearly one order of magnitude smaller. The basic idea is that one can construct the pure B-mode CMB map by using the E–B separation method proposed by Smith & Zaldarriaga (SZ) or the one considering the template cleaning (TC) technique, then apply the QML estimator to these scalar fields. By simulating potential observations of space-based and ground-based detectors, we test the reliability of these estimators by comparing them with the corresponding results of the traditional QML estimator and the pure B-mode pseudo-C

Contaminante: A Tool for Automatically Finding a Close-to-optimal Aperture for Transiting Signals in Kepler, K2, and TESS Data
Authors: Hedges Christina , Saunders Nicholas , Martínez-Palomera Jorge
Published: November 2021

Together, NASA’s Kepler/K2 and TESS missions have produced image data and time-series of millions of stars. These data have been used to identify thousands of transiting planet candidates. Unfortunately, some transiting signals do not originate from the target of the mission, and instead originate from background or blended eclipsing binaries. Exoplanet candidates can be vetted by searching for evidence that a detected transiting signal originates outside of the aperture. Centroiding tests, such as those employed by the Kepler Pipeline, have proved useful for vetting exoplanet candidates which have been falsely identified due to background contamination. However, centroiding tests are not able to provide a light curve of the true transiting target, which is valuable for vetting the origin of the signal. We present the contaminante Python tool which, given Kepler/K2 or TESS data, automatically builds a pixel aperture (An aperture is defined as a contiguous selection of pixels in a stack of imagettes, known as a Target Pixel File.) that maximizes the transiting signal at a given period, transit mid point and duration. In this research note, we describe the procedure we use to determine that optimal aperture, and show a demonstration of the contaminante tool on a Kepler false positive.
The Distribution of Silicon and Magnesium over the Surface of 21 Com
Authors: Monier Richard
Published: November 2021

Inspection of 10 individual spectra taken over the 24 hr monitoring of 21 Com with International Ultraviolet Explorer on 1991 April 17 reveals variations of low excitation lines of Si ii between rotational phases ϕ = 0.18 and ϕ = 0.65 of the 2 days period, suggesting a inhomogeneous repartition of silicon over the surface of 21 Com. The silicon lines are weaker at rotational phase ϕ = 0.18. More recent optical high resolution high signal-to-noise ELODIE spectra taken in 2004 April confirm the variations of silicon lines from phase ϕ = 0.99 to ϕ = 0.47. The synthesis of the optical Si ii lines yields estimates of the abundances of silicon: 8 times solar at phase 0.99 and 10 times solar at phase 0.47. The large FUV variations of 21 Com appear then to be partly due to changes in the silicon line and continuous opacity as the star rotates. In contrast, the Mg ii lines do not show convincing variations between the two rotational phases observed in the optical.

Authors: Lin Lei , Xu Mengxiang , Mo Er , Huang Shenghai , Qi Xiaoliang , Gu Siyi , Sun Weijie , Su Qiudong , Li Jin , Zhao Yun-e
Published: November 2021

PURPOSE:

To compare the accuracy of the Barrett Universal II, Emmetropia Verifying Optical (EVO), Haigis, Kane, and SRK/T formulas for intraocular lens power calculation in patients with high axial myopia.

METHODS:

In this retrospective study, 175 eyes (175 patients) that underwent uneventful cataract surgery were enrolled. According to the axial length (AL), the eyes were divided into long AL (26 ⩽ AL < 28 mm), super long AL (28 ⩽ AL < 30 mm), and extremely long AL (⩾ 30 mm). The mean absolute prediction errors (MAE) 3 months postoperatively and the percentage of eyes within different prediction error were compared, followed by subgroup analysis.

RESULTS:

The MAE and percentage of eyes within ±0.50 diopters (D) of the five formulas were as follows: Barrett Universal II (0.342, 74.9%), EVO 2.0 (0.314, 82.3%), Haigis (0.336, 74.9%), Kane (0.318, 78.9%), and SRK/T (0.398, 69.7%) (
P
= .552 and .071, respectively). Although no significant difference was found among the five formulas in the super and extremely long AL groups (
P
= .792 and .227, respectively), the EVO 2.0 formula achieved the highest accuracy (88.9%, 72 of 81) in the long AL group (
P
= .049). Moreover, the accuracy of the EVO 2.0 and Haigis formulas was stable, regardless of AL. The SRK/T formula showed a negative trend in the long and super long AL groups, whereas the Barrett Universal II, Kane, and SRK/T formulas showed positive trends in the extremely long AL group.

CONCLUSIONS:

Overall, the EVO 2.0 and Kane formulas achieved better results in patients with high axial myopia, whereas the other three formulas showed slightly poor outcomes.

An out-of-distribution-aware autoencoder model for reduced chemical kinetics
Authors: Zhang Pei , Liu Siyan , Lu Dan , Sankaran Ramanan , Zhang Guannan
Published: November 2021

While detailed chemical kinetic models have been successful in representing rates of chemical reactions in continuum scale computational fluid dynamics (CFD) simulations, applying the models in simulations for engineering device conditions is computationally prohibitive. To reduce the cost, data-driven methods, e.g., autoencoders, have been used to construct reduced chemical kinetic models for CFD simulations. Despite their success, data-driven methods rely heavily on training data sets and can be unreliable when used in out-of-distribution (OOD) regions (i.e., when extrapolating outside of the training set). In this paper, we present an enhanced autoencoder model for combustion chemical kinetics with uncertainty quantification to enable the detection of model usage in OOD regions, and thereby creating an OOD-aware autoencoder model that contributes to more robust CFD simulations of reacting flows. We first demonstrate the effectiveness of the method in OOD detection in two well-known datasets, MNIST and Fashion-MNIST, in comparison with the deep ensemble method, and then present the OOD-aware autoencoder for reduced chemistry model in syngas combustion.
Asymptotic behavior of nonlocal partial differential equations with long time memory
Authors: Xu Jiaohui , Caraballo Tomás , Valero José
Published: November 2021

In this paper, it is first addressed the well-posedness of weak solutions to a nonlocal partial differential equation with long time memory, which is carried out by exploiting the nowadays well-known technique used by Dafermos in the early 70's. Thanks to this Dafermos transformation, the original problem with memory is transformed into a non-delay one for which the standard theory of autonomous dynamical system can be applied. Thus, some results about the existence of global attractors for the transformed problem are {proved}. Particularly, when the initial values have higher regularity, the solutions of both problems (the original and the transformed ones) are equivalent. Nevertheless, the equivalence of global attractors for both problems is still unsolved due to the lack of enough regularity of solutions in the transformed problem. It is therefore proved the existence of global attractors of the transformed problem. Eventually, it is highlighted how to proceed to obtain meaningful results about the original problem, without performing any transformation, but working directly with the original delay problem.

We introduce a new class of generalized graphic fuzzy $ F $- contractive mappings on metric spaces and establish the existence of common fuzzy coincidence and fixed point results for such contractions. It is significant to note that we do not use any form of continuity of mappings to prove these results. Some examples are provided to verify our proven results. Various developments in the existing literature are generalized and extended by our results. It is aimed that the initiated concepts in this work will encourage new research aspects in fixed point theory and related hybrid models in the literature of fuzzy mathematics.

In the case of an epidemic, the government (or population itself) can use protection for reducing the epidemic. This research investigates the global dynamics of a delayed epidemic model with partial susceptible protection. A threshold dynamics is obtained in terms of the basic reproduction number, where for $ R_0 < 1 $ the infection will extinct from the population. But, for $ R_0 > 1 $ it has been shown that the disease will persist, and the unique positive equilibrium is globally asymptotically stable. The principal purpose of this research is to determine a relation between the isolation rate and the basic reproduction number in such a way we can eliminate the infection from the population. Moreover, we will determine the minimal protection force to eliminate the infection for the population. A comparative analysis with the classical SIR model is provided. The results are supported by some numerical illustrations with their epidemiological relevance.
Salvador Rueda en El Globo (1885-1888). El aprendizaje de la prosa narrativa
Authors: Jiménez Morales María Isabel
Published: November 2021

Este artículo estudia el vínculo literario entre Salvador Rueda y El Globo, importante diario madrileño con el que mantendrá una estrecha relación entre agosto de 1885 y marzo de 1888. En él se establece cuándo y cómo entró a formar parte de su redacción, acabando con algunas inexactitudes extendidas entre los críticos. En El Globo, el autor malagueño –hasta entonces conocido solo como poeta– publicó más de un centenar y medio de crónicas periodísticas, cartas y, sobre todo: cuentos, artículos de costumbres y estampas líricas, que supusieron su aprendizaje de la prosa narrativa. Algo más del centenar de estos textos los agrupó Rueda en sus volúmenes de prosa breve, publicados entre 1886 y 1893; pero una tercera parte de ellos quedaron olvidados en las páginas de El Globo. Este artículo se ocupa, por un lado, del proceso de transmisión de los primeros artículos y, por otro, se centra en el análisis del segundo grupo de textos, hasta el momento sin investigar, complementando los estudios que actualmente se han llevado a cabo y contribuyendo al mejor conocimiento de la obra en prosa del escritor malagueño.

Investigation presents an experimental study of mechanical properties of hybrid bio-composites made from man-made cellulose fibres and soft wood microfiller embedded into polypropylene homopolymer matrix at different weight contents. Mechanical properties such as elastic modulus, tensile strength, and impact resistance of the reinforced composites determined for various total weight contents of both biobased fillers were used as the design parameters. The problem was solved by planning the experiments and response surfaces method. The results demonstrate that using the both filler types enhance the mechanical properties. The tensile modulus increases by ~115%. The bio-composite with the highest weight content of man-made cellulose fibres and the lowest content of soft wood microfibers possesses maximum tensile strength (more 66 MPa). Addition of man-made cellulose fibres demonstrate a significant influence on the impact resistance of the investigated composites.

Authors: Skrinda Mārīte , Dubnika Arita , Locs Janis
Published: November 2021

Liposomes are being used as unique drug delivery systems due to their ability to encapsulate both hydrophilic and hydrophobic drugs, as well as for the fact that they improve the disadvantages of free drug administration. However, liposomes have a significant disadvantage - low encapsulation efficiency. In the research carried out, 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC) and cholesterol (Chol), in the ratio (n/n) of 2:1, 3:1 and 4:1 respectively, were used to prepare the liposomes. Blank liposomes (LIP) and vancomycin hydrochloride (VANKA) containing liposomes (VANKA-LIP) were prepared for each of the DSPC and Chol compositions. The aim of our study was to evaluate the effect of liposome composition on the VANKA encapsulation efficiency and release kinetics.

African swine fever is a severe animal infectious disease caused by African swine fever virus (ASFV), and the morbidity and mortality associated with virulent ASFV isolates are as high as 100%. Previous studies showed that the ability of ASFV to antagonize IFN production is closely related to its pathogenicity. Here, we report that ASFV HLJ/18 infection induced low levels of type I IFN and inhibited cGMP-AMP–induced type I IFN production in porcine alveolar macrophages that were isolated from specific pathogen-free Landrace piglets. Subsequently, an unbiased screen was performed to screen the ASFV genes with inhibitory effects on the type I IFN production. ASFV pI215L, a viral E2 ubiquitin–conjugating enzyme, was identified as one of the strongest inhibitory effectors on the production of type I IFN. Knockdown of pI215L expression inhibited ASFV replication and enhanced IFN-β production. However, inhibition of type I IFN production by pI215L was independent of its E2 enzyme activity. Furthermore, we found that pI215L inhibited type I IFN production and K63-linked polyubiquitination of TANK-binding kinase 1 through pI215L-binding RING finger protein 138 (RNF138). ASFV pI215L enhanced the interaction between RNF138 and RNF128 and promoted RNF138 to degrade RNF128, which resulted in reduced K63-linked polyubiquitination of TANK-binding kinase 1 and type І IFN production. Taken together, our findings reveal a novel immune escape mechanism of ASFV, which provides a clue to the design and development of an immune-sensitive attenuated live vaccine.

Exploring Challenges to COVID-19 Vaccination in the Darfur Region of Sudan
Authors: Mohamed Alanood Elnaeem , Elhadi Yasir Ahmed Mohammed , Mohammed Nora Alnaeem , Ekpenyong Aniekan , Lucero-Prisno Don Eliseo
Published: November 2021

The current COVID-19 pandemic has affected the ability of health systems to provide essential services globally. The Darfur region, located in the western part of Sudan, has been largely devastated by the war that began in 2003 and has been drawing considerable attention from the international community. The war, which erupted as a result of environmental, political, and economic factors, has led to tragic outcomes. Collapsing health-care infrastructures, health workforce shortages, lack of storage facilities for medicines and medical products, and inadequate access to health services are some of the effects of the war. After Sudan received the AstraZeneca COVID-19 vaccine through the COVID-19 Vaccines Global Access facility, significant challenges have been implicated in the delivery, storage, and use of the vaccine in the Darfur region. Lack of vaccine storage and transportation facilities, vaccination hesitancy, inequity in the distribution to health facilities, and shortage of health-care professionals resulting from insecurity and instability have added an extra layer of burden on local authorities and their ability to manage COVID-19 vaccinations in the region adequately. Addressing the impact of COVID-19 requires an effectively managed vaccination program. In the face of current challenges in Darfur, ensuring a fully vaccinated population might remain far-fetched and improbable if meaningful efforts are not put in place by all stakeholders and actors to address some of the challenges identified.

Authors: Galvagno María Inés , Vallejo Mario , Villafañe Silvia Teresa , González Daniel Enrique , Fernández María Cristina
Published: November 2021

Introducción: El plomo es un contaminante ambiental frecuente, y la exposición crónica a bajos niveles produce alteraciones en el área cognitiva y neuroconductual. La población más vulnerable es los niños entre 6 meses y 6 años. Actualmente, valores de plombemia (Pbs) mayores a 5 ug/dl requieren de una intervención. Sin embargo, no existe límite de seguridad en lo que se refiere a plombemia y neurotoxicidad.Población y Métodos: Se realizó un estudio prospectivo, descriptivo, aleatorizado en el Hospital Garrahan entre agosto de 2010 y abril de 2011, incluyéndose los pacientes que concurrieron espontáneamente a la consulta ambulatoria (Bajo y Mediano Riesgo) provenientes de la Cuenca Matanza Riachuelo, entre 1 y 6 años de edad. Resultados: Se incluyeron 237 pacientes, 2,7 años de edad promedio. Casi el 36% de la población incluída presentó plombemias mayores a 5 ug/dl. Del cuestionario surgió, como diferencia significativa entre los grupos, la existencia de algún trabajo de riesgo RR 3,9 (IC 95% 1,7 a 8,6) p0.0004 (metalúrgicos, mecánicos, gasistas –litargirio-, recolección de chatarra). El 94% presentó disminución significativa de la Pbs después de la intervención.

Conclusiones: La prevalencia de la población estudiada fue 36% (n:85p) para valores mayores a 5ug/dl. Con el cumplimiento de las medidas higiénico-ambientales propuestas, se logró una disminución significativa de la Pbs de los niños expuestos. Identificar las fuentes ambientales potenciales e instar a su eliminación es de suma importancia en la consulta pediátrica.
Stolberg’s Typology of Religioscientific Frameworks and Science and Religion Education in Ghana
Authors: Appiah Simon Kofi
Published: November 2021

This  research  took  cue  from  Stolberg’s  work  on  the typology  of  religioscientific  frameworks  in  the  teaching and  learning  of  science  and  religion  to  examine  the importance  of  the  intense  religious  orientation  of Ghanaians  for  developing  science  education  curriculum for  Ghanaian  institutions  of  learning.    Using  group interview  and  qualitative  survey,  the  study  investigated the  beliefs  and  preferred  strategies  for  life  used  by students  of  the  University  of  Cape  Coast.  It  was  found that  participants  were  not  unaware  of  scientific convictions  and  solutions,  but  their  beliefs  and  strategies tended  more  towards  the  cultural  religious  construction of  life,  where  religion  would  seem  to  constitute  an important source of knowledge with science playing only a  pragmatic  role.  The  study  concluded  that  it  was important for science education curriculum developers to consider  the  religious  frameworks  of  teachers  and learners when designing science education curriculum.
Maurolico e Pascal: Indução Matemática e Demonstração por Exemplificação
Authors: Fossa John A.
Published: November 2021

A Indução Matemática foi aparentemente inventada por Francesco Maurolico e reformulada e reestruturada por Blaise Pascal. Nas suas demonstrações do passo da indução dos seus argumentos, todos os dois recorreram a demonstrações por exemplificação. Nesse sentido, o argumento de Maurolico é satisfatório, enquanto o de Pascal não o é. O método de Pascal, no entanto nos fornece um algoritmo para resolver toda instância particular coberta por sua proposição.

In Poland there are still nearly 20 million individuals with hypercholesterolaemia, most of them are unaware of their condition; that is also why only ca. 5% of patients with familial hypercholesterolaemia have been diagnosed; that is why other rare cholesterol metabolism disorders are so rarely diagnosed in Poland. Let us hope that these guidelines, being an effect of work of experts representing 6 main scientific societies, as well as the network of PoLA lipid centers being a part of the EAS lipid centers, certification of lipidologists by PoLA, or the growing number of centers for rare diseases, with a network planned by the Ministry of Health, improvements in coordinated care for patients after myocardial infarction (KOS-Zawał), reimbursement of innovative agents, as well as introduction in Poland of an effective primary prevention program, will make improvement in relation to these unmet needs in diagnostics and treatment of lipid disorders possible.

Authors: Ostrowska Ewa , Gąsecka Aleksandra , Mazurek Tomasz , Kochman Janusz
Published: November 2021

Introduction

Coronary artery perforation (CAP) is an infrequent, yet life-threatening complication of percutaneous coronary interventions, posing a major risk of cardiac tamponade and mortality.

Material and methods

We report on effective management of Ellis type III CAP with use of double-guiding catheter technique and stent-graft implantation.

Results

Prolonged balloon inflation via the first guiding catheter allows for temporary closure of the bleeding site. At the same time, stent-graft is inserted via the second guiding catheter to seal the perforation. After rapid deflation of the balloon, the stent is immediately advanced and expanded.

Conclusions

The procedure minimises the time between deflation of the balloon and implantation of the stent-graft, allowing for successful bleeding cessation.
Crisis Perception, Experience, and Preparedness among Managers in Ghana
Authors: Mensah Edwin , Ziemnowicz Christopher , Parnell John
Published: November 2021

Research about organizations and possible crisis events that may affect their operations or have negative consequences is wide-ranging. Recommendations include establishing crisis management plans and developing alternatives to deal with potential disasters. Most of the crisis management literature focuses on large businesses in developed countries. This study surveys the perceptions, preparedness, and involvement concerning crisis occurrences among managers in Ghana, an emerging nation. Initial findings suggest indigenous Ghanaian managers recognize the need for crisis preparation, but at the same time, may not invest the time, energy, and resources that are needed to be prepared. This study shows that Ghanaian firms with foreign ownership or control have in place crisis management policies typically found within large international businesses. This paper outlines the crisis management background and literature, presents the situation in Ghana, and reports on the survey conducted in Ghana. Our suggestions should assist managers of indigenous firms in Ghana.
