Published: May 2020

В статье дается методическое описание некоторых аспектов урока по РКИ, направленных на формирование и развитие профессиональных компетенций иностранных студентов-медиков, обучающихся на медицинских факультетах в вузах Российской Федерации. Несмотря на различные подходы к осуществлению теоретической профессиональной медицинской подготовки иностранцев (полное/частичное обучение на английском языке илиполное/частичное обучение на русском языке), формирование иразвитие практических навыков происходит в реальных условиях в лечебных учреждениях РФ. Такая практика предполагает хороший уровень владения навыками профессиональной коммуникации, которые можно приобрести только на практических занятиях по русскому языку. Работая в тандеме с медиками-клиницистами, русист согласовывает содержательно-тематические аспекты, разрабатывает стратегии и тактики урока, целью которого является подготовка инофонов кклинической практике в лечебных учреждениях РФ.

The article provides a methodological description of some aspects of the lesson in Russian as a foreign language, aimed on the formation and development of professional competencies of foreign medical students studying at medical faculties in universities of the Russian Federation. Despite the different approaches to the implementation of theoretical professional medical training of foreigners (full/partial training in English or full/partial training in Russian), the formation and development of practical skills takes place in real conditions in medical institutions of the Russian Federation. This practice requires a good level of proficiency in professional communication skills, which can only be acquired in practical classes in the Russian language. Working in tandem with clinicians, the Russian scholar coordinates the thematic and substantive aspects, develops strategies and tactics of the lesson, the purpose of which is to prepare foreign phones for clinical practice in medical institutions of the Russian Federation.

The article deals with the peculiarities of verbalization of key concepts and ideas of RuNet. The author puts forward an assumption that the formation and renewal of common Internet lexis primarily takes place in key conceptual fields reflecting mans activity in the Internet. They are connected both with the main object information, and with all the basic components of this activity (aim, means, result, process). Proceeding from this assumption the author singles out such key conceptual fields as information, its characteristics and their evaluation search and storage of information communication technical and technological base of the Internet. The case study of Russian Internet lexis formed in the last twenty years enables the author to analyse the process of neologization, to point out the facts that influence this process and make a conclusion about the peculiarities of RuNet lexis formation.

The article describes methods for determining damage from digital images on various hard surfaces. Research in this field is relevant for a wide range of industrial enterprises that specialize in the production of various kinds of materials: parts, marble slabs, building materials, etc. To solve this problem, it is proposed to use the k-means clustering method. It has been experimentally established that Gaussian blurring algorithms, the Hough transform, and the Kenny algorithm are best suited for recognizing defects on the surface of a marble slab. The developed complex method based on the theory of pattern recognition allows you to quickly identify defects and damage on the surfaces of marble slabs. On the basis of the method, a system for understanding defects is implemented in software. The main stages of the system are described in the article.

Статья посвящена оценке параметров помех экспериментальным путем. В статье рассмотрены технология LTE, основные параметры и услуги технологии LTE, проведен расчет внутренних параметров. Установлено, что потери зависят от расстояния между передатчиком и антенной. Результаты, полученные в ходе проведения данного эксперимента, показали, что при использовании аппаратуры сотовой связи в зоне обслуживания радиусом порядка 1,9 км связь в направлении АС-БС будет устанавливаться в 90 времени и мест с отношением сигнал/шум на выходе приемника не хуже 16 дБ. Как видно из расчетов, технология LTE обеспечивает эффективное радио покрытие и может работать с высокими скоростями для абонентов, находящихся в центре и на границе соты иметь достаточно хороший уровень сигнала.

The article is devoted to experimental estimation of interference parameters. The article discusses LTE technology, the main parameters and services of LTE technology, and calculates the internal parameters. Introduction of LTE technology in the Republic of Kazakhstan is currently an urgent topic. LTE technology is one of the most high-speed mobile access technologies. The main advantage of LTE is the so-called open Internet access. This means that a mobile network subscriber can access the Internet using the most convenient device at the moment a mobile phone, PDA, smartphone, or laptop that has the most suitable characteristics for the current exchange of information. It is established that the losses depend on the distance between the transmitter and the antenna. The results obtained during this experiment showed that when using cellular communication equipment in the service area with a radius of about 1.9 km, communication in the direction of the AC-BS will be established at 90 of the time and places with a signal-to-noise ratio at the receiver output is no worse 16 dB As can be seen from the calculations, LTE technology provides effective radio coverage and can operate at high speeds, for subscribers located in the center and at the cell border to have a fairly good signal level.
Beyond the Economic Approach
Authors: Jedličková Barbara
Published: May 2020

Due to the nature of competition law, which deals with business behaviour affecting the economy, it is not surprising that it is economic and not legal theories which have shaped the ‘modern’ approach. The dominant theoretical stream in competition law is welfare economics, informed by the neoliberal thinking of the Chicago and Post-Chicago Schools. In order to determine the anti-competitiveness of certain conduct, welfare economics applies a consequentialist approach by determining economic harm; anticompetitive harm occurs if total or consumer welfare and efficiency decrease.
Fighting Cartels and Corporate Corruption - Public versus Private Enforcement Models
Authors: Bronitt Simon , D'Amico Alessia
Published: May 2020

Our ambition is to examine the legal responses to cartel wrongdoing, drawing insights and parallels with new and emerging models of corporate responsibility applied to deal with other white-collar crimes. Our article traces how traditional legal binaries — public versus private law, and criminal versus civil law — are being increasingly challenged by legal hybridity, and the emergence of a range of new regulatory tools that meld together a wide range of purposes including prevention, deterrence, retribution, incapacitation, restorative justice, restitution and compensation.
Redress Facilitation Orders as a Sanction Against Corporations
Authors: Fisse Brent
Published: May 2020

The PhD thesis upon which Laura was working before her tragic death sought to resolve the intractable question of whether two key goals of anti-cartel enforcement, namely (a) deterrence and (b) compensation, can be achieved more effectively by integrating their pursuit. The potential capacity of redress facilitation orders both to facilitate compensation and to enhance deterrence is one aspect of that question. This article canvasses the possibility of redress facilitation orders designed to facilitate compensation for loss caused by cartel and other unlawful conduct and at the same time to enhance deterrence. It advances a statutory model for redress facilitation orders under the Competition and Consumer Act 2010 (Cth) (CCA). The model advanced is Australian in legislative style but could readily be adapted elsewhere.
Arbitrability of Cartel Damages Claims in the European Union
Authors: Nazzini Renato
Published: May 2020

In this article, I decided to discuss the topical question of whether and, if so, in what circumstances, cartel damages claims can be arbitrated in the European Union. International arbitration plays a central role in resolving disputes in the international business community. It is often considered speedier and more cost-effective than litigation. It gives the parties a similarly final and enforceable award to litigation, but with considerable advantages in terms of the choice of the arbitrators, procedural flexibility and neutrality of the forum. As such, it is considered favourably by most legal systems.
Indigenous Ecological Knowledge and the Environment: The Akan Perspective
Authors: Antwi Joseph Kofi
Published: May 2020

There are a number of academic studies that suggest that conservational values embedded in religio-cultural thoughts could be used in collaboration with science in finding lasting solutions to the environmental problems. However, despite these abundant studies and advocacy, environmentalists have ignored these in environmental management strategies. It is against this background that this paper examines the relevance of Akan indigenous ecological knowledge to environmental management strategies in Ghana. Three qualitative techniques were employed in this study: key-informant personal interviews, participant observation and focus-group discussion. The paper argues that there are a number of resources and concepts in Akan indigenous knowledge systems that help to conserve the natural environment. It is believed that the sacredness of these conservational resources can contribute to the pursuit of effective ways of curbing the crisis, which is the ultimate objective of policy-makers. In the process, the paper engages through critical analysis the argument for and against integrating Indigenous Ecological Knowledge (IEK), in the quest for finding a lasting solution to the environmental crisis in Ghana. The paper argues that IEK contains vast knowledge and moral values that can inform contemporary conservational strategies. The paper notes that IEK ensures the survival of not only the natural environment but the people as well. The paper therefore challenges Ghanaian environmentalists, ethicists, researchers and policy-makers on the need for a critical engagement with IEK.
THE HETEROGENEOUS EFFECTS OF CSR DIMENSIONS ON FINANCIAL PERFORMANCE – A NEW APPROACH FOR CSR MEASUREMENT
Authors: Su Rongjia , Liu Chunping , Teng Weili
Published: May 2020

This paper investigates the differential effects of corporate social responsibility (CSR)
dimensions on corporate financial performance (CFP) across sectors in China. This research uses a unique data set
provided by China Stock Market and Accounting Research (CSMAR), showing expenditure on CSR programs from 568
Chinese publicly traded firm-year observations from 2008 to 2017. Compared to previous studies using scores
produced by extra-financial rating agencies, this research quantifies CSR efforts by corporate expenditure
on CSR practices, which offers quantitative and precise information in explaining the CSR-CFP link. The results
show that the dimension of the environment has negative effects on financial performance in capital-intensive
manufacturing industries. The impact of HR expenditure on CFP is negative in the tertiary sector and
resourceintensive manufacturing industries. However, CSR investments in the community are positively related
to financial performance in resource-intensive industries and other secondary sector (mining, construction,
and utilities). Firms, in general, could gain benefits when spending more on business and financial stakeholders.
Observational Features of Exoplanetary Synchrotron Radio Bursts
Authors: Gao Yang , Qian Lei , Li Di
Published: May 2020

The magnetic fields of exoplanets shield the planets from cosmic rays and interplanetary plasma. Due to the interaction with the electrons from their host stars, the exoplanetary magnetospheres are predicted to have both cyclotron and synchrotron radio emissions, neither of which have been definitively identified in observations. As the coherent cyclotron emission has been extensively studied in the literature, here we focus on planetary synchrotron radiation with bursty behaviors (i.e., radio flares) caused by the outbreaks of energetic electron ejections from the host star. Two key parameters of the bursty synchrotron emissions, namely the flux density and burst rate, and two key features, namely the burst light curve and frequency shift, are predicted for star–hot Jupiter systems. The planetary orbital phase–burst rate relation is also considered as the signature of star–planet interactions. As examples, previous X-ray and radio observations of two well-studied candidate systems, HD 189733 and V830 τ, are adopted to predict their specific burst rates and fluxes of bursty synchrotron emissions for further observational confirmations. The detectability of such emissions by current and upcoming radio telescopes shows that we are at the dawn of discoveries.
ALMA Observations of the Molecular Clouds in NGC 625
Authors: Imara Nia , De Looze Ilse , Faesi Christopher M. , Cormier Diane
Published: May 2020

We present the highest-resolution (1″) 12CO observations of molecular gas in the dwarf starburst galaxy NGC 625 to date, obtained with Atacama Large Millimeter/submillimeter Array. The molecular gas, which is distributed in discrete clouds within an area of 0.4 kpc2, does not have well-ordered large-scale motions. We measure a molecular mass in NGC 625 of 5.3 × 106

, assuming a Milky Way CO-to-

 conversion factor. We use the CPROPS package to identify molecular clouds and measure their properties. The 19 resolved CO clouds have a median radius of 20 pc, a median linewidth 2.5

, and a median surface density of 169

. Larson scaling relations suggest that molecular clouds in NGC 625 are mostly in virial equilibrium. Comparison of our high-resolution CO observations with a star formation rate map, inferred from ancillary optical observations, suggests that about 40% of the molecular clouds coincide with the brightest H ii regions. These bright H ii regions have a range of molecular gas depletion timescales, all within a factor of ∼3 of the global depletion time in NGC 625 of 106–134 Myr. The highest surface density molecular clouds toward the southwest of the galaxy, in a region we call the Butterfly, do not show strong star formation activity and suggest a depletion timescale longer than 5 Gyr.
A Kinematic View of NGC 1261: Structural Parameters, Internal Dispersion, Absolute Proper Motion, and Blue Straggler Stars

Published: May 2020

We constructed a Hubble Space Telescope (HST) astrophotometric catalog of the central region of the Galactic globular cluster NGC 1261. This catalog, complemented with Gaia DR2 data sampling the external regions, has been used to estimate the structural parameters of the system (i.e., core, half-mass, tidal radii, and concentration) from its resolved star density profile. We computed high-precision proper motions thanks to multi-epoch HST data and derived the cluster velocity dispersion profile in the plane of the sky for the innermost region, finding that the system is isotropic. The combination with the line-of-sight information collected from spectroscopy in the external regions provided us with the cluster velocity dispersion profile along the entire radial extension. We also measured the absolute proper motion of NGC 1261 using a few background galaxies as a reference. The radial distribution of the Blue Straggler Star population shows that the cluster is in a low/intermediate phase of dynamical evolution.
Supermassive Black Holes as Possible Sources of Ultrahigh-energy Cosmic Rays
Authors: Tursunov Arman , Stuchlík Zdeněk , Kološ Martin , Dadhich Naresh , Ahmedov Bobomurat
Published: May 2020

The production and acceleration mechanisms of ultrahigh-energy cosmic rays (UHECRs) of energy >1020 eV, clearly beyond the GZK cutoff limit, remain unclear, which points to the exotic nature of the phenomena. Recent observations of extragalactic neutrinos may indicate that the source of UHECRs is an extragalactic supermassive black hole (SMBH). We demonstrate that ultraefficient energy extraction from a rotating SMBH driven by the magnetic Penrose process (MPP) could indeed fit the bill. We envision ionization of neutral particles, such as neutron beta decay, skirting close to the black hole horizon that energizes protons to over 1020 eV for an SMBH of mass 109
M
⊙ and magnetic field 104 G. Applied to the Galactic center SMBH, we have a proton energy of order ≈1015.6 eV that coincides with the knee of the cosmic-ray spectra. We show that large γ

z
factors of high-energy particles along the escaping directions occur only in the presence of an induced charge of the black hole, which is known as the Wald charge in the case of a uniform magnetic field. It is remarkable that the process requires neither an extended acceleration zone nor fine-tuning of accreting-matter parameters. Further, this leads to certain verifiable constraints on the SMBH’s mass and magnetic field strength as the source of UHECRs. This clearly makes the ultraefficient regime of the MPP one of the most promising mechanisms for fueling the UHECR powerhouse.
Does Modified Gravity Predict Fast Stellar Bars in Spiral Galaxies?
Authors: Ghafourian Neda , Roshan Mahmood , Abbassi Shahram
Published: May 2020

The evolution of disk galaxies in modified gravity is studied by using high-resolution N-body simulations. More specifically, we use the weak field limit of two modified gravity theories, that is, nonlocal gravity and scalar–tensor–vector gravity, known as MOG, and ignore the existence of a dark matter (DM) halo. We construct the same models as in the standard DM model and compare their dynamics with the galactic models in modified gravity. It turns out that there are serious differences between galactic models in these different viewpoints. For example, we explicitly show that the galactic models in modified gravity host faster bars compared to the DM case, but the final stellar bars are weaker in modified gravity. These facts are not new and have already been reported in our previous simulations for exponential galactic models. Therefore, our main purpose is to show that the above-mentioned differences, with an emphasis on the speed of the bars, are independent of the initial density profile of the adopted disk and halo. To do so, we employ different profiles for the disk and halo and show that the results remain qualitatively independent of the initial galactic models. Moreover, a more accurate method has been used to quantify the kinematic properties of the stellar bars. Our results imply that, contrary to the DM models, bars in modified gravity are fast rotators that never leave the fast-bar region until the end of the simulation.

The surface characterization of Trans-Neptunian binaries (TNBs) is key to understanding the properties of the disk of planetesimals from which these objects formed. In the optical wavelengths, it has been demonstrated that most equal-sized component systems share similar colors, suggesting they have a similar composition. The color homogeneity of binary pairs contrasts with the overall diversity of colors in the Kuiper Belt, which was interpreted as evidence that Trans-Neptunian objects (TNOs) formed from a locally homogeneous and globally heterogeneous protoplanetary disk. In this paradigm, binary pairs must have formed early, before the dynamically hot TNOs were scattered out from their formation location. The latter inferences, however, relied on the assumption that the matching colors of the binary components imply matching composition. Here, we test this assumption by examining the component-resolved photometry of three TNBs found in the Outer Solar System Origins Survey: 505447 (2013 SQ99), 511551 (2014 UD225), and 506121 (2016 BP81), across the visible and J-band near-infrared wavelength range. We report similar colors within 2σ for the binary pairs, which is suggestive of similar reflectance spectra and hence surface composition. This advocates for gravitational collapse of pebble clouds as a possible TNO formation route. However, we stress that several similarly small TNOs, including at least one binary, have been shown to exhibit substantial spectral variability in the near-infrared, implying color equality of binary pairs is likely to be violated in some cases.
Recovery and Validation of Mars Ionospheric Electron Density Profiles from Viking Orbiter Radio Occultation Observations
Authors: Withers Paul , Felici Marianna , Flynn Casey , Vogt Marissa F.
Published: May 2020

The Viking Orbiter radio occultation experiment acquired vertical profiles of electron density in the ionosphere of Mars. As these profiles were not archived, they were thought to have been lost. Here, we report the recovery and validation of the complete set of high-quality, dayside electron density profiles from Viking Orbiters 1 and 2. Sixty-nine profiles spanning solar zenith angles of 50°–95° were deemed acceptable for scientific analysis. Relative to the widely used set of radio occultation electron density profiles from Mars Global Surveyor, these Viking profiles have better sensitivity, higher vertical extent, more global coverage, and greater solar zenith angle coverage. They are ready for use in scientific investigations of the ionosphere of Mars and related topics. They accompany this article as supplemental information.

Quality of Experience in Mobile Applications: A Systematic Mapping of Metrics and Tools
Authors: Collazo Garcia Antonio , Casas Sandra
Published: May 2020

Context: Quality of Experience (QoE) enables the description of user perceptions about the performance of a particular application or service. In the mobile computing context, it is an important measure for service providers and users, since QoE makes it possible to improve it and make it more competitive to achieve user fidelity. In turn, the importance of QoE in mobile technologies increases due to the various factors that affect the applications that run on mobile devices. Objective: The purpose of this study is to identify the metrics and tools relevant to the scientific community for the QoE analysis of mobile applications. Method: A systematic mapping study was conducted. Results: From a total of 751 studies, 33 were selected, and 13 metrics and 15 mobile QoE analysis tools were identified. Conclusions: The existing mobile QoE analysis tools collect and calculate metrics automatically, combining objective and subjective metrics. However, they present limited approaches, making it difficult to carry out an integral analysis of the applications.
Digimesh-Based Design of a Wireless Monitoring Network for Environmental Factors Affecting Granary System
Authors: Onibonoje Moses Oluwafemi , Baandele Jeremiah Oluwatosin
Published: May 2020

The monitoring of granaries were earlier implemented with wired networks in most Asia countries with obvious challenges that include high installation and maintenance costs, data acquisition delay, and high energy consumption. Most other works being implemented with wireless approaches presented inherent drawbacks that include inefficient coverage of the grain storage bins and high rate of node failure. This paper presents the design and tremendous advantages of deploying distributed wireless sensor network based on Digimesh network protocol, to monitor the environmental temperature, humidity and illumination of a granary system. The monitoring system has only one node type, and consists of a homogenous network in which all nodes route data and they are interchangeable. A node consists of Xbee transceiver modules, Arduino microcontroller and DHT22 Temperature/Humidity sensor, and it is being configured as low battery powered devices. The results were logged real-time on a personal computer for analysis, display and record. The results indicate a system which provides a better sleeping scheme and eliminate the single point of failure associated with Zigbee and some other network protocols.

Published: May 2020

With the increasing penetration of the distributed generation driven by renewable energy in distribution systems, there is a need to analysis fault currents for the next generation utility and smart grid systems. The steady state fault current contribution from Type 4 wind turbines is not calculated accurately by traditional short circuit analysis techniques. A new formulation for calculating the short circuit current sharing from voltage source converter wind turbines is presented, and taken into consideration the real behaviour of the type 4 WT during three phase short circuit in the electric system. The results are compared with that obtained from the dynamic simulation results using Power World Simulator program, which has the generation of Western Electricity Coordinating Council (WECC) generic model. The percentage difference between the two results is about one percent that verify the effectiveness of the proposed formulation
Symptoms of Acute Posttraumatic Stress Disorder After Intensive Care
Authors: Wallen Karen , Chaboyer Wendy , Thalib Lukman , Creedy Debra K.
Published: May 2020

Background Admission to intensive care is often a sudden and unexpected event precipitated by a life-threatening condition, 2 determinants thought to influence the development of posttraumatic stress disorder.

Objectives To identify the frequency of acute symptoms of posttraumatic stress disorder and to describe factors predictive of these symptoms in patients 1 month after discharge from intensive care.

Methods In this prospective cohort study, all patients meeting the inclusion criteria during the study period were invited to participate. Participants completed the Impact of Event Scale-Revised, and demographic and clinical data were accessed from an intensive care unit database.

Results During a 9-month period, 114 of 137 patients who met the inclusion criteria consented to participate in the study, and 100 (88%) completed it. The mean total score on the Impact of Event Scale-Revised was 17.8 (SD, 13.4; possible range, 0–88). A total of 13 participants (13%) scored higher than the cutoff score for clinical posttraumatic stress disorder. Neither sex nor length of stay was predictive of acute symptoms of post-traumatic stress disorder. In multivariate analysis, the only independent predictor of symptoms was age. Patients younger than 65 years were 5.6 times (95% confidence interval, 1.17–26.89) more likely than those 65 years and older to report symptoms.

Conclusion The rate of symptoms of posttraumatic stress disorder 1 month after discharge from intensive care was relatively low. Consistent with findings of previous research, being younger than 65 years was the only independent predictor of symptoms.

Published: May 2020

Background Despite practice guidelines promoting delirium assessment in intensive care, few data exist regarding current delirium assessment practices among nurses and how these practices compare with those for sedation assessment.

Objectives To identify current practices and perceptions of intensive care nurses regarding delirium assessment and to compare practices for assessing delirium with practices for assessing sedation.

Methods A paper/Web-based survey was administered to 601 staff nurses working in 16 intensive care units at 5 acute care hospitals with sedation guidelines specifying delirium assessment in the Boston, Massachusetts area.

Results Overall, 331 nurses (55%) responded. Only 3% ranked delirium as the most important condition to evaluate, compared with altered level of consciousness (44%), presence of pain (23%), or improper placement of an invasive device (21%). Delirium assessment was less common than sedation assessment (47% vs 98%, P < .001) and was more common among nurses who worked in medical intensive care units (55% vs 40%, P = .03) and at academic centers (53% vs 13%, P < .001). Preferred methods for assessing delirium included assessing ability to follow commands (78%), checking for agitation-related events (71%), the Confusion Assessment Method for the Intensive Care Unit (36%), the Intensive Care Delirium Screening Checklist (11%), and psychiatric consultation (9%). Barriers to assessment included intubation (38%), complexity of the tool for assessing delirium (34%), and sedation level (13%).

Conclusions Practice and perceptions of delirium assessment vary widely among critical care nurses despite the presence of institutional sedation guidelines that promote delirium assessment.
Maintenance of Germinal Center B Cells by Caspase-9 through Promotion of Apoptosis and Inhibition of Necroptosis
Authors: Zhang Jingting , Kodali Srikanth , Chen Min , Wang Jin
Published: May 2020

In response to T cell–dependent Ag encounter, naive B cells develop into germinal center (GC) B cells, which can further differentiate into Ab-secreting plasma cells or memory B cells. GC B cells are short lived and are prone to caspase-mediated apoptosis. However, how apoptotic caspases regulate GC B cell fate has not been fully characterized. In this study, we show that mice with B cell–specific knockout of caspase-9 had decreases in GC B cells and Ab production after immunization. Caspase-9–deficient B cells displayed defects in caspase-dependent apoptosis but increases in necroptosis signaling. Additional deletion of Ripk3 restored GC B cells and Ab production in mice with B cell–specific knockout of caspase-9. Our results indicate that caspase-9 plays an important role in the maintenance of Ab responses by promoting apoptosis and inhibiting necroptosis in B cells.

Over the past years there has been substantial growing interest in the prodromes of psychosis to identify individuals at risk for psychosis prior to their first psychotic episode. Researchers have proposed criteria to detect young adults at Ultra-High Risk (UHR) for psychosis, and these criteria have also been applied to children and adolescents, though few clinical studies have examined this population. This theoretical perspective presents some of the crucial issues in the assessment and treatment of UHR children and adolescents: the presence of a specific clinical profile (i.e., different to that of healthy controls and UHR young adults), the predictive value of UHR criteria, and the presence and clinical significance of suicidal thinking and behaviour. In UHR children and adolescents, like UHR young adults, the presence of Attenuated Psychotic Symptoms (APS) is the most frequently reported inclusion criterion at baseline, with a prevalence of approximately 89–100%. In addition, there are frequently non-psychotic comorbid diagnoses of depressive and anxiety disorders. In contrast to the UHR adult population, UHR children and adolescents demonstrate a lower conversion rate to frank psychosis, most likely due to their high rate of APS. Finally, UHR adolescents report a high prevalence of suicidal ideation and self-injurious behaviour (67.5%), as well as a significantly greater frequency of attempted suicide, relative to adolescents with frank psychosis. On this basis, UHR children and adolescents report a clinical complexity that should be carefully monitored and considered for specific and targeted therapeutic interventions to be planned and developed

BackgroundCytoreductive surgery was developed as a treatment for peritoneal carcinomatosis. However, this surgery is associated with important complications. The present study aimed to assess the relationship between lactacidemia and the rate of associated complications during the immediate postoperative period in the intensive care unit (ICU) in patients undergoing cytoreductive surgery.MethodsThis was a retrospective observational study. A total of 57 patients underwent cytoreductive surgery. All patients were admitted to the ICU immediately after the surgery. Data on lactic acid levels at the time of admission and discharge from the ICU were collected. Postsurgical complications that occurred during the ICU stay were recorded according to failure-to-rescue analysis and their severity stratified according to the Clavien-Dindo classification.ResultsThe lactic acid levels at admission to the ICU were significantly higher in patients who developed complications, with an almost tripled unadjusted relative risk (2.9, 95% CI: 1.6, 5.3), than in those who did not develop complications for the lactacidemia threshold established in the cumulative sum curve graphs. After adjustment for confounding effects, the relative risk became even higher (3.1, 95% CI: 1.8, 3.6). Lactic acid levels were still significantly higher in this group at the time of discharge from the ICU.ConclusionsSerum lactate level is a risk factor for postoperative complications in patients undergoing cytoreductive surgery for peritoneal carcinomatosis. This study suggests that the risk of developing severe complications almost triples with a lactic acid level of 2.5 mmol/L or higher at the time of admission in the ICU.
Prevalence of hypertension among professional drivers

Published: May 2020

Background:

Hypertension is one of the leading causes of premature deaths worldwide. Drivers have an additional risk of hypertension when compared to the general population because of the nature of their profession. Hence, the current review was done to estimate the global burden of hypertension among professional drivers.

Methods:

We conducted a systematic search for articles on the prevalence of hypertension among drivers published from 2000 to 2017 in Medline and Embase. Meta-analysis was performed using the random-effects model and pooled prevalence of hypertension was reported. Heterogeneity was assessed using the likelihood ratio (LR) test and publication bias was assessed using Egger's test.

Results:

In total, 26 studies with 15,702 drivers were included. The pooled prevalence of hypertension among the drivers worldwide was 34% (95% confidence interval [CI]: 27–40%). World Health Organization (WHO) region-wise estimates showed that prevalence was highest among the drivers in the Western Pacific region (56%) and lowest in the Eastern Mediterranean and African region (21%). Studies showed significant evidence of heterogeneity (Χ2= 1816.1,P< 0.001) but there was no significant publication bias (P= 0.967).

Conclusion:

More than one-third of drivers have hypertension globally which is in excess of the general population. Hence, more focus needs to be given for allocating resources and developing workplace interventions for prevention and control of hypertension.
Fulminant amebic colitis

Published: May 2020

Amebiasis caused by protozoa Entamoeba histolytica (EH) is the third leading parasitic cause of human mortality. Although amebiasis is endemic in India, only about 10% of the infected individuals manifest disease. Clinical spectrum of amebiasis ranges from asymptomatic colonization to amebic colitis to hemorrhagic and fulminant colitis. Factors causing an invasive infection are not completely understood. Pathogen virulence, host immunity, and ability of the pathogen to evade host immune response play vital role in determining the disease course. Host factors such as immunocompromised states may make an individual susceptible to develop symptomatic infection. Malignancies usually result in chronic debilitation which may make the individual prone to develop invasive amebiasis with rapid progression. We report two cases of invasive amebiasis which developed a fulminant course in the immediate postoperative period after abdominal surgeries for visceral malignancies.
Procesos de obtención del licor de pétalos de rosas
Authors: Mendoza-Pico Vicky
Published: May 2020

El presente trabajo de investigación es una revisión bibliográfica enfocada en la obtención de licor con características específicas, las cuales se deben a la presencia de un aceite esencial proveniente de los pétalos de rosas, estos pétalos son considerados como rechazo de la industria florícola y su destino final es el compostaje. El aprovechamiento de este subproducto radica en que el aceite esencial logra modificar el sabor y color del licor elaborado, dándole un valor agregado al producto final. Para elaborar una bebida alcohólica se consideran varios procesos que pueden variar dependiendo de la materia prima que se utilice, los cuales pueden ser maceración, arrastre de vapor, extracción sólido-liquido, entre otros; además se evidencia que los licores suelen producirse con sustancias adicionales y entre ellas se encuentran flores como: rosa, lavanda, azafrán, que son consideradas como el ingrediente principal. Debido a que en Ecuador el 80% de la industria florícola pertenece a plantaciones de rosas que en su mayoría son destinadas a la exportación, generando residuos que son utilizados como compostaje; el proceso más adecuado para llevar a cabo este producto es la extracción sólido-líquido a temperatura ambiente con etanol como solvente, esto se debe a que el etanol es parte de la composición del producto final y además mantiene las propiedades características del aceite esencial que se extrae de los pétalos de rosas.

Palabras clave: rosa, extracción, sólido-líquido, destilación, licores.
SİNOP GAZETESİ’NE GÖRE SİNOP’TA MÜBADELE (1923-1927)
Authors: ÇEVİK Umut
Published: May 2020

Antik çağdan itibaren Karadeniz’in önemli bir liman kenti olan Sinop, Anadolu’dan Karadeniz’e ya da Karadeniz’den Anadolu’ya açılan göç yollarının kilit taşlarından biri olmuştur. Bu özelliğini Türkiye ve Yunanistan arasında imzalanan mübadele anlaşması neticesinde de devam ettirmiştir. Mübadele dönemi ile binlerce arşiv belgesi bulunmasına rağmen genellikle istatistiki bilgiler üzerinde durulmuş, bu belgelerde mübadillerin içinde bulunduğu psikolojik durum, ekonomik, sağlık ve iskân problemleri ya da mübadele bölgesindeki yerleşik halkın tutumunun çoğu zaman göz ardı edildiği görülmüştür. Bu kapsamdaki bilgileri en iyi yansıtan yerel basın olmuştur. Bu çalışma ile birlikte, 12 Haziran 1922 tarihinde yayın hayatına başlayan Sinop Gazetesi’ndeki mevcut bilgiler kullanılarak, gelen ve giden mübadiller hakkında sayısal veriler, mübadele ve iskân müdürlüğünün idari yapısı, Sinop’a yerleşen mübadillerin ekonomik ve sosyal sorunları ile Sinop halkının mübadillere karşı tutumu incelenerek, döneme ışık tutulmaya çalışılmıştır.
