Abstract. To provide insight into the planetary boundary layer (PBL) production of ozone (O3) over the North China Plain, the Air chemistry Research
in Asia (ARIAs) campaign conducted aircraft measurements of air pollutants over Hebei Province, China, between May and June 2016. We evaluate vertical profiles of trace gas species including O3, nitrogen oxides (NOx), carbon monoxide (CO), and volatile organic
compounds (VOCs) and relate to rates of O3 production. This analysis shows measured O3 levels ranged from 45 to
146 ppbv, with the peak median concentration (∼ 92 ppbv) occurring between 1000 and 1500 m. The NOx
concentrations exhibited strong spatial and altitudinal variations, with a maximum of 53 ppbv. Ratios of CO∕CO2 indicate the
prevalence of low-efficiency combustion from biomass burning and residential coal burning but indicate some success of regional pollution controls
compared to earlier studies in China. Concentrations of total measured VOCs reveal alkanes dominate the total measured volume mixing ratio of VOCs
(68 %), and sources include vehicular emissions, fuel and solvent evaporation, and biomass burning. Alkanes and alkenes/alkynes are responsible
for 74 % of the total VOC reactivity assessed by calculating the OH loss rates, while aromatics contribute the most to the total ozone formation
potential (OFP) (43 %) with toluene, m/p-xylene, ethylene, propylene, and i-pentane playing significant roles in the aloft production of
O3 in this region. In the PBL below 500 m, box model calculations constrained by measured precursors indicate the peak rate of
mean O3 production was ∼ 7 ppbv h−1. Pollution frequently extended above the PBL into the lower free troposphere around
3000 m, where NO2 mixing ratios (∼ 400 pptv) led to net production rates of O3 up to
∼ 3 ppbv h−1; this pollution can travel substantial distances downwind. The O3 sensitivity regime is determined to be
NOx-limited throughout the PBL, whereas it is more VOC-limited at low altitudes near urban centers, demonstrating that control of both
VOCs and NOx is needed to reduce aloft O3 pollution over Hebei.
The Impact of Volcanic Eruptions of Different Magnitude on
Stratospheric Water Vapour in the Tropics
Authors: Kroll Clarissa Alicia , Dacie Sally , Azoulay Alon , Schmidt Hauke , Timmreck Claudia
Published: November 2020

Abstract. Volcanic eruptions increase the stratospheric water vapour (SWV) entry via long wave heating through the aerosol layer in the cold point region, and this additional SWV alters the atmospheric energy budget. We analyze tropical volcanic eruptions of different eruption strengths with sulfur (S) injections ranging from 2.5 Tg S up to 40 Tg S using EVAens, the 100-member ensemble of the Max Planck Institute – Earth System Model in its low resolution configuration (MPI-ESM-LR) with artificial volcanic forcing generated by the Easy Volcanic Aerosol (EVA) tool. Significant increases in SWV are found for the mean over all ensemble members from 2.5 Tg S onward ranging between [5,160] %, while for single ensemble members the standard deviation between the control run members (0 Tg S) is larger than SWV increase of single ensemble members for the eruption strengths up to 20 Tg S. A historical simulation using observation based forcing files of the Mt. Pinatubo eruption, which was estimated to have emitted (7.5 ± 2.5) Tg S, returns SWV increases slightly higher than the 10 Tg S EVAens simulations due to differences in the aerosol profile shape. An additional amplification of the tape recorder signal is also apparent, which is not present in the 10 Tg S run. These differences underline that it is not only the eruption volume, but also the aerosol layer shape and location with respect to the cold point that have to be considered for post-eruption SWV increases. The additional tropical clear sky SWV forcing for the different eruption strengths amounts to [0.02, 0.65] W/m2, ranging between [2.5, 4] percent of the aerosol radiative forcing in the 10 Tg S scenario. The monthly cold point temperature increases leading to the SWV increase are not linear with respect to AOD nor is the corresponding SWV forcing, among others, due to hysteresis effects, seasonal dependencies, aerosol profile heights, and feedbacks. However, knowledge of the cold point temperature increase allows for an estimation of SWV increases with a 12 % increase per Kelvin increase in mean cold point temperature, and yearly averages show an approximately linear behaviour in the cold point warming and SWV forcing with respect to the AOD.
Smoke-charged vortices in the stratosphere generated by wildfires
and their behaviour in both hemispheres: comparing Australia 2020
to Canada 2017

Published: November 2020

Abstract. The two most intense wildﬁres of the last decade that took place in Canada in 2017 and Australia in 2019–2020 were followed by large injections of smoke in the stratosphere due to pyroconvection. It was discovered by Khaykin et al. (2020) and Kablick et al. (2020) that, after the Australian event, part of this smoke self-organized as anticyclonic conﬁned vortices that rose in the mid-latitude stratosphere up to 35 km. Based on CALIOP observations and the ERA5 reanalysis, this new study analyzes the Canadian case and ﬁnd, similarly, that a large plume penetrated the stratosphere by 12 August 2017 and got trapped within a meso-scale anticyclonic structure which travelled across the Atlantic. It then broke into three offsprings that could be followed until mid-October performing three round the world journeys and rising up to 23 km. We analyze the dynamical structure of the vortices produced by these two wildﬁres and demonstrate how they are maintained by the assimilation of data from instruments measuring the signature of the vortices in the temperature and ozone ﬁeld. We propose that these vortices can be seen as bubbles of low absolute potential vorticity and smoke carried vertically across the stratiﬁcation from the troposphere inside the middle stratosphere by their internal heating, against the descending ﬂux of the Brewer-Dobson circulation.
Ångström exponent errors prevent accurate visibility
measurement

Abstract. Visibility is an indicator of atmospheric transparency and is widely used in many research fields, including air pollution, climate change, ground transportation, and aviation. Although efforts have been made to improve the performance of visibility meters, a significant error exists in measured visibility data. This study conducts a well-designed simulation calibration of visibility meters, which proves that current methods of visibility measurement include a false assumption, which leads to the long-term neglect of an important source of visibility error caused by erroneous values of Ångström exponents. This error has two characteristics. (1) Independence, in which the magnitude of the error is independent of the performance of the visibility meter. It is impossible to reduce this error by improving the performance of visibility meters. (2) Uncertainty, in which the magnitude of the error does not show a clear change pattern but can be substantially larger than the measurement error of visibility meters. It is impossible to accurately estimate the magnitude of this error nor its influence on visibility measurements. Our simulations indicate that, as errors in visibility caused by erroneous values of Ångström exponents are inevitable using current methods of visibility measurement, reliable visibility data cannot be obtained without major adjustments to current visibility measurement methods.
Earth system feedbacks following large-scale tropical forest
restoration
Authors: Koch Alexander , Brierley Chris , Lewis Simon L.
Published: November 2020

Abstract. To achieve the Paris Agreement requires aggressive mitigation strategies alongside negative emission technologies. Recent studies suggest that increasing tree cover can make a substantial contribution to negative emissions, with the tropics being the most suitable region from a biogeophysical perspective. Yet these studies typically do not account for subsequent carbon cycle and climate feedback processes of large-scale land use change. Here we quantify the maximum potential temperature and CO2 benefits from pantropical forest restoration, including earth system feedbacks, using a fully-coupled, emission-driven Earth System Model (HadGEM2-ES). We perform an idealised experiment where all land use in the tropics is stopped and vegetation is allowed to recover, on top of an aggressive mitigation scenario (RCP 2.6). We find that tropical restoration of 1529 Mha increases carbon stored in live biomass by 130 Pg C by 2100 CE. Whilst avoiding deforestation and tropical restoration in the tropics removes 42 Pg C compared to RCP 2.6, feedback processes mean that carbon in the atmosphere only reduces by 18 Pg C by 2100. The resulting, small CO2 (9 ppm) benefit does not translate to a detectable reduction in global surface air temperature compared to the control experiment. The greatest carbon benefit is achieved 30–50 years after restoration before the Earth System response adjusts to the new land-use regime and declining fossil fuel use. We identify three model-independent key points: (i) the carbon benefit of restoration is CO2-scenario dependent, (ii) in a world that follows Paris Agreement emission cuts restoration is best deployed immediately, and (iii) the ocean carbon feedbacks will reduce the efficacy of negative emissions technologies. We conclude that forest restoration can reduce peak CO2 mid-century, but can only be a modest contribution to negative emissions.
A Mechanistic Analysis of Tropical Pacific Dynamic Sea Level in
GFDL-OM4 under OMIP-I and OMIP-II Forcings

Published: November 2020

Abstract. The sea level over the tropical Pacific is a key indicator reflecting vertically integrated heat distribution over the ocean. Here we use the Geophysical Fluid Dynamics Laboratory OM4 (GFDL-OM4) global ocean-sea ice model forced by both the CORE and JRA55-do atmospheric states (OMIP-I and OMIP-II) to evaluate the model performance and biases compared against available observations. We find persisting mean state dynamic sea level (DSL) bias along 9° N even with updated wind forcing in JRA55-do relative to CORE. The mean state bias is related to biases in wind stress forcing and geostrophic currents in the 4° N to 9° N latitudinal band. The simulation forced by JRA55-do significantly reduces the bias in DSL trend over the northern tropical Pacific relative to CORE. In the CORE forcing, the anomalous westerly wind trend in the eastern tropical Pacific causes an underestimated DSL trend across the entire Pacific basin along 10° N. The simulation forced by JRA55-do significantly reduces the bias in DSL trend over the northern tropical Pacific relative to CORE. We also identify a bias in the easterly wind trend along 20° N in both JRA55-do and CORE, thus motivating future improvement. In JRA55-do, an accurate Rossby wave initiated in the eastern tropical Pacific at seasonal time scale corrects a biased seasonal variability of the northern equatorial counter-current in the CORE simulation. Both CORE and JRA55-do generate realistic DSL variation during El Nino. We find an asymmetry in the DSL pattern on two sides of the equator is strongly related to wind stress curl that follows the sea level pressure evolution during El Niño.
Detained Children: Vulnerability, Violence and Violation of Rights
Authors: Haydon Deena
Published: November 2020

The United Nations Convention on the Rights of the Child (UNCRC) establishes provisions and protections to which under-18s are entitled; establishing state obligations to ensure the realisation of children’s rights for all, including ‘disadvantaged’ or ‘vulnerable’ groups. This article focuses on children in England and Wales deprived of their liberty in secure care for their own or others’ protection or in custody as a result of criminal justice proceedings. It explores the proposition that secure care and custody exacerbate the existing vulnerabilities of detained children, especially in custodial settings where violence is institutionalised. Demonstrating consistent breaches of international standards, it considers the actions required to ensure the implementation of rights and effective accountability through policy and practice grounded in social justice priorities.
Gut microbiome and checkpoint inhibitor colitis
Authors: Sehgal Kanika , Khanna Sahil
Published: November 2020

Immune checkpoint inhibitor therapies such as ipilimumab, are increasingly being used as a treatment option for a variety of cancers, including metastatic melanoma and have demonstrated effectively a prolonged survival. These agents have an immunological mode of action that predisposes patients to a number of immune-related adverse events, colitis being one of the most commonly encountered complications. The pathogenesis for the development of colitis is unclear, and there is a growing consensus that the ecosystem of the gastrointestinal microbiota plays a significant role. Based on this suspected connection, studies are being carried out to explore the changes in the microbiota in patients on these medications who develop colitis. Conceivably, the modulation of the gut microbiota could offer a therapeutic benefit. Fecal microbiota transplantation is one therapeutic option that is currently being investigated, though there are still more data needed to evaluate its efficacy. In this review, we recapitulate the mechanisms of action of immune checkpoint inhibitors, their adverse events, with a focus on colitis and the role gut microbiota are suspected to play, and finally discuss the microbiota modulation therapies being investigated.
The Alleviation Mechanism of “The Predicament of Helping Others”: An Experimental Investigation
Authors: Zhu Cuicui , Liu Jun
Published: November 2020

In recent years, there are many news reports about “the predicament of helping the falling elderly”. Many scholars treat this predicament as a social and moral issue. Few scholars explore it from the holistic perspective. This thesis discusses the influencing factors of the predicament, including the positive and negative aspects of the news reports, individual sense of security and reward-punishment mechanism. Based on two priming experiments, this paper tests the following hypotheses: (1) the positive news report enhances people’s willingness to help the old; (2) the higher the level of the subject’ sense of security, the greater his willingness to raise the old up; (3) the reward-punishment mechanism also enhances people’s willingness to give a hand. These conclusions show that this predicament is not simply a moral or legal issue, but an outcome of the transaction among the parties involved, macro systems and micro contexts. In addition, this study also found that there are significant differences in people’s willingness to help the old between acquaintance society and strangers society. And, social justice has a positive impact on people’s tendency to help. Therefore, the news media should bear the social responsibility that guides positive public opinion when pursuing objective news report. At the same time, the state and society should design the appropriate reward-punishment mechanism to resolve the predicament. All of these should be based on methodological relationalism.
Criminal Protection of Privacy in the Jordanian Cybercrime Law No. 27 of 2015
Authors: Irtaimeh Wejdan Suleiman
Published: November 2020

This study deals with the issue of criminal protection of privacy in the Jordanian Cybercrime Law No. 27 of 2015, as the great developments in computer technologies and the widespread use of the Internet have led to the emergence of new forms of electronic crimes related to the protection of the privacy of individuals. The study indicated that the Jordanian legislator did not include in the Jordanian Constitution or in the Cybercrime Law any definition of the right to privacy that delineates its boundaries and clarifies its features. The study concluded that the Cybercrime Law was ambiguous in some of its articles, especially those related to the protection of the right to privacy. The Jordanian legislator did not include special provisions that explicitly criminalize assault on privacy, as it included provisions for other crimes that include assault on this right, which made it lose clarity, precision and accuracy of wording. Moreover, such provisions omitted other forms of electronic crimes related to the right to privacy, which constituted a legislative deficiency. The study concludes that there is a need to amend the Cybercrime Law No. 27 of 2017 and to have explicit provisions that stipulate the criminalization of assault on privacy, as well as the need to issue a special law to protect the personal information of individuals.

Transportation is vital in accessing healthcare services as well as reducing maternal mortality. This study examined clients’ perception of the role of transportation to the hospital and level of hospital in reducing maternal mortality in Calabar. This study was a cross-section descriptive design. Four (4) research questions were developed for the study. A total of 220 participants were recruited by proportionate sampling technique. Respondents were selected from four clinic days Tuesdays, Wednesdays, Thursdays and Fridays in each visit for a period of two weeks were used for the study. A structured questionnaire was used to collect data. The data were analysed using frequencies and percentages. The finding of the study revealed that: 153 (68%) agreed that good transportation increases the number of times participants go for an antenatal visit. 159 (72%) of the respondents viewed that good roads and vehicles make a journey to the hospital quick and easy. 177 (62%) opined that the best way to visit the hospital is by one’ s car or a taxi drop. 203 (93%) agreed that hospital has skilled midwives and doctors; 153 (70%) agreed that level of the hospital is reflective of low maternal and infant deaths; 159 (72%) agreed that healthcare team are highly skilled in handling both complicated and uncomplicated deliveries. 181 (78%) supports the notion that transportation plays a huge role in the reduction of maternal mortality in Calabar; 148 (67%) agreed that good road network has an indirect role in reducing maternal mortality in Calabar; 146 (67%) opined that controlled traffic helps reduced maternal mortality in Calabar, and 159 (71%) agreed that lack of access to transport for women in labour can increase stillbirth and maternal death rates. The study concludes that a good road network should be provided to reduce maternal mortality in Calabar.

Published: November 2020

Virtual (VR) and augmented reality (AR) have emerged from the framework of academic and industrial laboratories and have acquired global attention. Currently, the focus shifted from the technologies themselves to finding adequate teaching and learning applications. In this paper, the students' attitudes toward the application of mobile AR (MAR) in higher education (HE) were researched (with a focus on augmented textbooks). The results showed that the students have a mostly positive attitude, and it is concluded that there was no statistically significant difference between the STEM (science, technology, engineering, and mathematics) and non-STEM students' opinions regarding this topic. Based on the results, the further research and integration of this technology into HE settings can be suggested.
Galen
Authors: Supady Jerzy
Published: November 2020

After Hippocrates, Galen was one of the most outstanding physicians of the ancient world. He was born in Pergamon in c. 131 AD, but soon upon completion of his medical studies he went to become physician-in-ordinary to the Roman Emperors. Being devoted to his studies, he made a lot of discoveries in the field of anatomy and physiology. In pathology, he based his ideas on Hippocrates teaching. In diagnostics, he examined pulse and urine. He wrote about 500 treatises of which only 117 writings have survives to this day. Galen’s scientific achievements have contributed enormously to the development and progress of medical sciences. His authority was unquestionable in Europe for over 15 centuries. Galen died in Rome in c. 201 AD.
Assessment of the impact of PTGS1, PTGS2 and CYP2C9 polymorphisms on pain, effectiveness and safety of NSAID therapies
Authors: Dawidowicz Miriam , Kula Agnieszka , Świętochowski Paweł , Ostrowska Zofia
Published: November 2020

Cyclooxygenase 1 and 2 (COX-1, COX-2) are enzymes that catalyze the first reaction in the arachidonic acid pathway. COXs are the therapeutic target for non-steroidal anti-inflammatory drugs. Inhibition of COX enzymatic activity has an analgesic, anti-inflammatory and sometimes antiplatelet effect. Single-nucleotide polymorphisms (SNPs) within genes encoding COX-1 and COX-2 (PTGS1, PTGS2) influence the risk of pain and their intensity in some diseases. They also affect the effectiveness of NSAID therapy in rheumatoid diseases. Moreover, the relationship between certain polymorphisms of PTGS2 and a higher risk of migraine and the development of aspirin resistance in the prophylaxis of cardiovascular diseases was demonstrated. The isoform of cytochrome P450, CYP2C9 has a significant influence on the efficacy and safety of NSAID use. It is responsible for the metabolism and speed of removal of these drugs. The occurrence of some of its polymorphic forms is associated with a decrease in CYP2C9 enzymatic activity, leading to changes in the pharmacokinetics and pharmacodynamics of NSAIDs. The prolonged half-life and decrease in clearance of these drugs lead to serious side effects such as hepatotoxicity, nephrotoxicity, anaphylactic reactions, cardiovascular or gastrointestinal incidents. Studies on polymorphisms of cyclooxygenases and CYP2C9 may improve the safety and efficacy of NSAIDs therapy by adjusting the dose to individual polymorphic variants, as well as expanding knowledge about the pathomechanism of inflammatory diseases.
The effect of the duration of the procedure on the risk of complications during pediatric cardiac catheterization
Authors: Evren Şahin Kübra
Published: November 2020

Background: This study aims to evaluate the frequency of and associated risk factors for adverse events caused by cardiac catheterization procedures in pediatric patients. Methods: Between January 2009 and January 2012, a total of 599 pediatric patients (320 males, 279 females; mean age 5.4±4.7 years; range, 1 day to 21 years) who underwent cardiac catheterization in our cardiac catheterization laboratory were retrospectively analyzed. Demographic and clinical data of the patients including the duration of the procedure, management of anesthesia, the American Society of Anesthesiologists class, and Catheterization Risk Score for Pediatrics, and procedure-related serious adverse events were recorded. Results: The incidence of procedure-related serious adverse events was 9.18%. Potential risk factors associated with serious adverse events were identified as interventional heart catheterization, high scores obtained from the Catheterization Risk Score for Pediatrics, the use of endotracheal tube in airway control, and prolonged procedural duration. Conclusion: Our study results suggest that prolonged duration of catheterization is a potential risk factor for procedure-related adverse events and the duration of the procedure needs to be included as a variable in the Catheterization Risk Score for Pediatrics scoring system for predicting procedure-related adverse events.
Latent class analysis for exploring distribution patterns of primary superficial venous insufficiency
Authors: Andaç Baltacıoğlu Nurten
Published: November 2020

Background: This study aims to identify specific segmental distribution patterns of lower extremity chronic venous disease based on latent class analysis of Doppler mapping results. Methods: A total of 1,871 lower extremities of 1,218 treatment-naïve patients (536 males, 682 females; mean age 45.4 years; range, 21 to 87 years) with chronic venous disease referred for Doppler examination between September 2009 and August 2018 were included. Refluxing superficial venous segments of the lower extremities were mapped and recorded in database in 10 distinct anatomic locations as follows: saphenofemoral junction and proximal greater saphenous vein, mid and distal thigh greater saphenous vein, anterior and posterior accessory saphenous veins, proximal and distal calf greater saphenous vein, saphenopopliteal junction and proximal lesser saphenous vein, distal lesser saphenous vein, and intersaphenous veins including Giacomini’s vein. Repeated examinations were excluded. The latent class analysis was applied to identify any possible anatomic distribution patterns of chronic venous disease. Results: Bayesian information criteria revealed three latent class models fit for refluxing segment distribution as follows: 58.2% (n=1,089) were above-the-knee greater saphenous vein segments including saphenofemoral junction (pattern 1); 29.3% (n=548) were below-the-knee greater saphenous vein segments (pattern 2); and 12.5% (n=234) were lesser saphenous vein segments and intersaphenous veins including Giacomini’s vein (pattern 3). There was no age- or sex-specific differences in the chronic venous disease distribution patterns. Conclusion: The latent class analysis, by identifying previously unseen subgroups within the sampled population, provides a new approach to classification of reflux patterns in chronic venous disease. Identification of latent classes may provide understanding of different pathophysiological bases of venous reflux and more optimal planning for interventions.

Management of endovascular treatment in spontaneous iliac artery dissections: Applications enabling classical surgery
Authors: Sevil Fehim Can
Published: November 2020

Background: This study aims to investigate the effectiveness of endovascular applications for the treatment of spontaneous iliac artery dissections. Methods: The medical records of 13 patients (12 males, 1 female; mean age 67.9±5.7 years; range, 58 to 75 years) with spontaneous iliac artery dissection between January 2017 and December 2019 were retrospectively reviewed. The diagnosis of spontaneous iliac artery dissection was made based on contrast-enhanced computed tomography. Demographic and clinical characteristics of the patients, physical examination and imaging findings, and hybrid treatments applied during endovascular treatment were analyzed. Results: The mean follow-up was 12.5±1.1 (range, 6 to 16) months. Five patients received hybrid treatment during endovascular treatment. The re-entry site was closed by a patch plasty over the common femoral artery in one of these patients. Embolectomy was performed in the remaining four patients for the treatment of acute ischemia of the extremities. Since no patency could be achieved in two of the patients undergoing embolectomy, a femoropopliteal bypass was performed. The technical success and primary patency rates were 100%. No new false lumen formation, intra-stent occlusion or arterial occlusion was observed during the hospital stay and follow-up. Conclusion: Endovascular methods can be safely used in the treatment of spontaneous iliac artery dissections; however, hybrid treatments may be also required in selected cases. We believe that it is effective and safe to apply endovascular and hybrid treatments without preventing possible surgical treatments which may be required in the future.

Information and Communication Technologies and Work-Life Balance: Practical Recommendations for Employers and Individuals
Authors: Jackson Diane , Young Valerie , Sander Alyson
Published: November 2020

For decades, the number and frequency of individuals who work from home has gradually increased, in many ways as a result of emergent Information and Communication Technologies (ICTs). This gradual increase, accelerated by the COVID-19 pandemic, has weathered away boundaries between work at work and work at home, with some positive and many negative outcomes. Currently, however, because of a global pandemic which necessitates ICTs for working from home, the impact that organizational technology assimilation has on the way that people engage with each other is increasingly important. This chapter reviews theory and research regarding organizational technology and concludes with pragmatic recommendations for individuals and organizations regarding work-related technology use at home.
Theoretical Aspects of Future Teachers Intellectuality Development
Authors: Et al. Lyaila Iskakova
Published: November 2020

The purpose of the study is to identify the main problems and prospects of the education system in the context of innovative development, as well as the intellectualism of future teachers. The authors of the article conducted a factor analysis of the ongoing reforms in the education system. The transition of the economy to the innovative way of development and the overall socio-economic situation in Kazakhstan and other countries requires a rethinking of some priorities prevailing in politics and focusing on building a new type of society based on the development and mutual integration of three main elements such as education, innovation, and research. These elements are impossible without intellectualism and critical thinking. The formation of innovation policy should contribute to the development of a set of measures in the system of higher professional pedagogical education that organize and stimulate innovative activities and promote the integration of education in the scientific and technical space. This integration process will serve as the basis for the formation of the strategy and tactics of innovative development based on intellectualism and critical thinking.
Migrace alkalických kovů ve zvětralinových profilech migmatitů ze svrateckého krystalinika a moldanubika
Authors: Buriánek David , Soukup Martin , Ivanov Martin
Published: November 2020

The purpose of this study was to characterize four soil profiles derived from migmatites were studied in the Moldanubicum and Svratka Crystalline Unit (eastern part of the Czech Republic). Both physical and chemical weathering biotite to muscovite-biotite migmatites produces 100 to 80 cm thick soil profiles. The silt (43–88 %) was the dominant fraction in all of the studied soil profiles. The weathering process studied migmatites start with biotite replaced to chlorite and continue decomposition plagioclase to the kaolinite. On the other hand, K-feldspar is less affected by secondary alterations and quartz is stable. Based on the study of the behavior of selected alkali metals we can interpret the mechanism of the formation of weathering profiles. The highest degree of the weathering indicates soil profile from the locality Rovné characterized by decreased content of K, Na, and Rb upwards from the parent rock to the A-horizon. The soil proﬁles from the localities Lipník and Zubří shows a higher proportion of sand fraction and lower WIP (> 50) in comparison to Rovné. Vertical distribution of alkali metals in the soil proﬁle from the locality Štěpánovice indicates that soil profile has been modified by secondary slope movements
Suspension syndrome
Authors: Lechner R , Rauch S
Published: November 2020

Suspension syndrome is a potentially fatal event of unknown incidence that can be caused by motionless hanging in the rope during rope-secured activities. During prolonged hanging, generalized hypoperfusion with reduced cerebral blood flow and consecutive loss of consciousness occurs. Two mechanisms are discussed as the cause leading to loss of consciousness: venous pooling in the legs and a sudden reduction of heart rate and blood pressure, similar to a neurocardiogenic syncope. The most important preventive measure is the activation of the muscle pump during hanging. In principle, the treatment follows standard ABCDE care. The patient should be rescued from the hanging position as fast as possible and airway obstruction caused by hyperflexion of the head during unconscious hanging has to be reversed. There is an increased risk of hyperkalemia. Therefore, ECG monitoring should be established as soon as possible to recognize cardiac arrhythmias. Pulmonary embolism should be considered as a potentially reversible cause of cardiac arrest. Hypothermia prophylaxis and treatment have high priority. For suspension longer than two hours, a medical treatment facility able to provide continuous renal replacement therapy should be chosen. There is no evidence that laying a patient flat immediately after rescue is harmful. Key Words: Neurocardiac Syncope, Venous Pooling, Rescue Death, Generalized Hypoperfusion, Standard ABCDE Care

Published: November 2020

Este texto tem como objetivo tensionar o uso das palavras em aulas de matemática. Discute-se a potência de rachar as palavras, discuti-las em âmbito etimológico, léxico-semântico, histórico. Para isso, trabalha-se com o procedimento genealógico no exercício de debruçar-se sobre as palavras e seus significados. Dos lugares provisórios de estar docente, docenciar-se, questiona-se quais os efeitos produzidos pelo deslocamento de uma posição estruturalista para um âmbito pós-estruturalista, especialmente com autores das filosofias da diferença, para pensar o atravessamento da linguagem – e atravessar a linguagem, em imanência – em aulas de matemática. Sob angulações do filósofo Friedrich Nietzsche, distanciamo-nos da concepção neutra e transparente da linguagem a fim de estabelecer relações menos estreitas e criar condições outras de pensamento com aulas de matemática. A ampliação de vocabulário, a formação de palavras por meio de um radical comum ou por prefixação/sufixação e a polissemia se apresentam como ferramentas para pensar um uso menos automático e mais compositivo das palavras, tomado aqui como uma atitude ética de inserção da docência em solo movente, no dinamismo que lhe é próprio.
A educação matemática e a fórmula n-1: rizoma e utopia
Authors: Vitkowski José Rogério
Published: November 2020

Este texto aborda a educação matemática enquanto plano de imanência ancorado  no referencial da filosofia da diferença ou multiplicidade, na vertente deleuze-guattariana, acrescido das observações  da prática educativa do autor.  Trata-se aqui de realizar  um exercício de pensamento  que intenta estabelecer vínculos entre a educação matemática e a filosofia.  O texto  destaca a crise de um paradigma científico arbóreo e se aproxima da imagem-conceito de rizoma.  Uma educação rizomática é a proposta inspiradora para o desenvolvimento de pautas relacionadas à educação matemática.
Shortening turnaround time for high-priority patients during the COVID-19 epidemic: evaluation of the Xpert Xpress SARS-CoV-2 test
Authors: Kogoj Rok , Resman Rus Katarina , Uršič Tina
Published: November 2020

Background: Although several molecular tests are now available for detecting SARS-CoV-2 RNA in nasopharyngeal swab samples, the number of requested tests exceeds the capacity of many diagnostic laboratories. Unfortunately, the available high-throughput platforms exhibit longer turnaround times than those required for management of high-priority patients.

Methods: The aim of this study was to evaluate the performance and possible benefits of the Cepheid Xpert Xpress SARS-CoV-2 test, focusing mainly on turnaround time when applied to high-priority patients. We evaluated the Xpert Xpress SARS-CoV-2 test in comparison to the Roche’s cobas 6800 SARS-CoV-2 test by monitoring turnaround times and by retrospectively testing 20 nasopharyngeal swabs from COVID-19 patients with various viral loads. In addition, 50 patients were tested by both methods prospectively.

Results: We observed a lower limit of detection of one SARS-CoV-2 genome equivalent/µL and 100% (95% CI, 92.6−100%) specificity and 95.5% (95% CI, 77.2−99.9%) sensitivity in comparison to the cobas SARS-CoV-2 test. When applying the Xpert Xpress SARS-CoV-2 test for high-priority patients the turnaround time could be greatly reduced, i.e. from 3 - 5 hours that take our routine diagnostics methods to about 1 hour.

Conclusion: The novel Xpert Xpress SARS-CoV-2 test is a useful, easy to perform tool, valuable for rapid and reliable diagnosis of COVID-19, especially in high-priority patients when a short turnaround time is of key importance for further patient management.

La persuasión y la retórica y El diálogo de la salud
Authors: Michelstaedter Carlo , Hernández González María Belén
Published: November 2020

La obra fundamental de Carlo Michelstaedter (Gorizia 1887-1910), el ensayo titulado La persuasión y la retórica, escrita en 1910, plantea el tema de la verdad a través de una palabra privada de su significado comunicativo, sometida a una laceración extrema, y sacrificada en pos de la utópica persuasión.
En efecto, la persuasión representa la utopía antirretórica absoluta, que pretende despojar de todo lo accesorio a la esencialidad del ser; sin embargo, está marcada por una imposibilidad: la naturaleza del lenguaje, que no puede renunciar a comunicar una finalidad o un deseo vital. Por ello, al tiempo que se acerca a la vida, la retórica también socava al pensamiento, y las palabras se empobrecen, convirtiéndose en ese lugar común por el que han transitado la sociedad y la cultura.
Michelstaedter inició la obra como trabajo de tesis de licenciatura para la Facultad de Letras de la Universidad de Florencia. Antes había realizado estudios de matemáticas en Viena, para desembocar definitivamente en la poesía y filosofía clásicas. El diálogo de la salud, fue redactado en paralelo ese mismo año, y refleja mediante un parlamento socrático entre dos jóvenes amigos, la tensión íntima del autor frente la conciencia de la muerte y la voluntad ética de dar a la existencia una forma auténtica, liberada de las dependencias y placeres de la vida.
Ambas obras fueron concluidas la víspera del suicidio de Carlo a los veintitrés años; los lectores contemporáneos no dudaron en calificarlo de "suicidio metafísico". En el centenario de los hechos, el lector actual reconocerá a uno de los más agudos pensadores del siglo; también al escritor que, como en el autorretrato de la portada a nuestra edición, no llegará nunca a envejecer.
