Hydraulic characteristics of countercurrent jets on adverse-sloped beds
Authors: Wang Lei , Li Zhen , Diao Ming-jun 
Published: September 2021

Abstract
The counter-current jet (CCJ) acts like a reverse surface jet layer covering the free jump surface and has potential applications in the energy dissipation of hydraulic engineering. The present study investigated the hydraulic characteristics of CCJs on adverse-sloped beds. The results showed that, compared to the horizontal bed, the slope didn't increase the energy dissipation rate of CCJ but reduced the return flow length and upstream depth. The velocity distribution along the depth was divided into the boundary layer region, mixing region, and reverse surface jet region. The velocity distribution in the boundary layer region and the mixing region was similar to the classical wall jet. The jet Froude number and the bed slope had no significant effect on the turbulence intensity distribution and turbulence kinetic energy (TKE) distribution of CCJ. The distribution of TKE was similar to that of a submerged jump. The maximum absolute turbulence intensity appeared at exactly half of the maximum velocity. The maximum TKE appeared at the mixing region. Besides, empirical formulas for estimating length scales and maximum velocity attenuation are proposed. The results could provide a reference for the potential application of CCJ in energy dissipation in hydraulic engineering.

Published: September 2021

Background
Monitoring linguistic cues from adolescents’ digital media use (DMU; ie, digital content transmitted on the web, such as through text messages or social media) that could denote suicidal risk offers a unique opportunity to protect adolescents vulnerable to suicide, the second leading cause of death among youth. Adolescents communicate through digital media in high volumes and frequently express emotionality. In fact, web-based disclosures of suicidality are more common than in-person disclosures. The use of automated methods of digital media monitoring triggered by a natural language processing algorithm offers the potential to detect suicidal risk from subtle linguistic units (eg, negatively valanced words, phrases, or emoticons known to be associated with suicidality) present within adolescents’ digital media content and to use this information to respond to alerts of suicidal risk. Critical to the implementation of such an approach is the consideration of its acceptability in the clinical care of adolescents at high risk of suicide.

Objective
Through data collection among recently suicidal adolescents, parents, and clinicians, this study examines the current context of digital media monitoring for suicidal adolescents seeking clinical care to inform the need for automated monitoring and the factors that influence the acceptance of automated monitoring of suicidal adolescents’ DMU within clinical care.

Methods
A total of 15 recently suicidal adolescents (aged 13-17 years), 12 parents, and 10 clinicians participated in focus groups, qualitative interviews, and a group discussion, respectively. Data were recorded, transcribed, and analyzed using thematic analysis.

Results
Participants described important challenges to the current strategies for monitoring the DMU of suicidal youth. They felt that automated monitoring would have advantages over current monitoring approaches, namely, by protecting web-based environments and aiding adolescent disclosure and support seeking about web-based suicidal risk communication, which may otherwise go unnoticed. However, they identified barriers that could impede implementation within clinical care, namely, adolescents’ and parents’ concerns about unintended consequences of automated monitoring, that is, the potential for loss of privacy or false alerts, and clinicians’ concerns about liability to respond to alerts of suicidal risk. On the basis of the needs and preferences of adolescents, parents, and clinicians, a model for automated digital media monitoring is presented that aims to optimize acceptability within clinical care for suicidal youth.

Conclusions
Automated digital media monitoring offers a promising means to augment detection and response to suicidal risk within the clinical care of suicidal youth when strategies that address the preferences of adolescents, parents, and clinicians are in place.

Authors: Gómez-Aguado de Alba Guadalupe Cecilia 
Published: September 2021

Uno de los personajes fundamentales del siglo XIX mexicano es Agustín de Iturbide. Pese a ello, ha sido olvidado en las conmemoraciones de la independencia debido a las difíciles circunstancias que enfrentó su efímero gobierno imperial . A lo largo de las décadas que siguieron a la consumación de la independencia las disputas políticas entre diversos proyectos de nación utilizaron a Iturbide como bandera de tendencias opuestas, hasta llegar al abierto enfrentamiento entre dos proyectos: liberalismo y conservadurismo. En este trabajo se hará un análisis de la figura de Iturbide en los textos de sus contemporáneos.

El Diclorodifeniltricloroetano (DDT) y Hexaclorociclohexano (HCH) son disruptores endócrinos cuya presencia en la leche representa un riesgo para la salud. Existe evidencia de que la pasteurización disminuye o incrementa la concentración de plaguicidas organoclorados en productos lácteos. La presente investigación evaluó el efecto de la pasteurización a 63 °C 30 min-1 y 73 °C 15 seg-1 en las concentraciones de DDT, HCH y sus metabolitos en leche bovina, para estimar la exposición dietaria por consumo humano de leche pasteurizada. Se realizó un diseño experimental de bloques al azar con dos tratamientosen 100 muestras de leche recolectadas en Soledad de Doblado y Jamapa, Veracruz, México. Los plaguicidas se cuantificaron por cromatografíade gases con detector de microcaptura de electrones. Los datos se analizaron mediante Análisis de Varianza unifactorial (P<0.05) y las medias se compararon con Tukey (P< 0.05). La exposición dietaria a plaguicidas se evaluó por laIngesta Diaria Estimada (IDE) y Dosis Diaria Promedio (DDP) en tres grupos de población. La pasteurización a 73 ºC disminuyó 30.94, 44.51, 3.18, 81.23 y 42.82 % las concentraciones de p,p'-DDE,p,p'-DDD, o,p'-DDT, p,p'-DDT y DDT total, respectivamente, así como las concentraciones de β-HCH, γ-HCH y HCH total (85.68, 18.88 y 99.31 %, respectivamente). La IDE para niños, adultos y ancianos de DDT total fue menor por consumo de leche pasteurizada a 73 ºC y de γ-HCH a 63 ºC. La DDP de DDT total disminuyó con la pasteurización a 73 °C. La exposición dietaria de DDT y HCH fue mayor en niños.
The Showgirls from Eltham, the Windmill Theatre and the V2 Rocket: One family’s experience as a window on aspects of interwar cultural life
Authors: Cocker Alan 
Published: September 2021

The journey of the Cooper family from small town New Zealand in the early 1920s to Sydney, and then to London, where they arrived in May 1935, provides a frame to look at aspects of social change in the interwar period. Their story, which sees the two daughters of the family appearing in the risqué nude revues at London's Windmill Theatre in the early years of the Second World War, could be viewed as exotic and atypical but does provide a vehicle to look at aspects of cultural change and media influence during a time when “modern women understood self-display to be part of the quest for mobility, self-determination, and sexual identity"1

Published: September 2021

Abstract
The research presents mutual coupling reduction between UWB-MIMO antenna elements using stub loading technique. The proposed 2 × 2 UWB antenna geometry consists of two circular-shaped monopole radiators with a partial ground for perfect impedance matching. Stubs of 20 mm × 0.2 mm are inserted between the two antenna elements in the ground plane to improve the isolation. The decoupling stub leads to a mutual coupling reduction of less than 20 dB. The farfield measurement at a selected frequency of 10 GHz confirms an omnidirectional radiation pattern. Different MIMO antenna metric such as channel capacity loss (CCL), mean effective gain (MEG), total active reflection coefficient (TARC), envelope correlation coefficient (ECC), and surface current are presented. Details of the design considerations and the simulation and measurement results are presented and discussed. The proposed MIMO antenna array can be well suited for UWB applications.

Published: September 2021

AbstractThe protection of power system is an essential trait in a huge network to efficiently detect and isolate the sections undergoing faults or abnormal behaviour. The key components of a protection scheme include circuit breakers, relays, switchgears and fuses which employ communication from one station to another to achieve high-speed tripping. The automation of these components at the laboratory level using programmable logic controller (PLC) along with supervisory control and data acquisition (SCADA) system owns paramount importance for intelligent decision making, sensing, actuating, monitoring and maintaining the record in the host server. This paper discusses such a technique for conventional power system protection laboratory at a new level of development to promote a control system through PLC and SCADA. The control system has indication of over and under values of voltage, load and frequency, which can trigger malfunctioning of equipment and must be rectified. Furthermore, ground fault and inverse current indication are added to the system for monitoring and controlling purposes. The proposed system enhances the efficiency and safety of the expensive equipment and the personnel to the next level and also introduces new standards of automated protection schemes for modern technical institutes.

Authors: Shcherba Vitaliy , Krynytska Inna , Marushchak Mariya , Korda Mykhaylo 
Published: September 2021

AbstractObjective.The aim of the present study was to investigate the presence of inflammatory mediators in rats with only periodontitis and periodontitis in a setting of hyper- and hypo-thyroidism and to analyze the correlative linkages between inflammatory mediators and thyroid hormones.Methods.White male 12–14 weeks old inbred rats (n=48) weighing 180–200 g were employed in the experiment. They were randomly divided into the following groups: Group I – control group, Group II – group with a model of periodontitis, Group III – group with a periodontitis in a setting of hyperthyroidism, and Group IV – group with periodontitis in a setting of hypothyroidism. The presence of tumor-necrosis factor-α (TNF-α) and interleukins IL-1β and IL-10 in the periodontal homogenate supernatant was studied by a solid-phase enzyme-linked immunosorbent assay.Results.It was shown that experimental lipopolysaccharide (LPS)-induced periodontitis is accompanied by hyperproduction of pro-inflammatory cytokines (TNF-α, IL-1β) and reduction of anti-inflammatory cytokines (IL-10), whereas TNF-α underwent to maximum changes. Thyroid dysfunction exacerbates cytokine imbalance and severity of inflammation in experimental LPS-induced periodontitis, especially pronounced at hyperthyroidism, as evidenced by the predominance of TNF-α and IL-1β levels in the periodontal homogenate supernatant by 38.5% (р<0.01) and 75.6% (p<0.001), respectively, hyperthyroid over the euthyroid, and by 20.1% (p<0.05) and 24.1% (p<0.05), respectively, over the hypothyroid rats.Conclusions.Thyroid dysfunction, especially hyperthyroidism, may play an important role in the pro-inflammatory response in periodontitis. Hyperproduction of inflammatory mediators in thyroid dysfunction can induce a noticeable damage in the whole apparatus of the periodontium, thereby causing progression of periodontitis.
Graves’ disease with spontaneous resolution following ocrelizumab in primary progressive multiple sclerosis
Authors: Duarte Diana Borges , Silva Ana Martins da , Freitas Claudia , Cardoso Helena 
Published: September 2021

Abstract

Objectives. Immune reconstitution therapies (IRT), which include antibody-based cell-depleting therapies targeting CD52+ (alemtuzumab) or CD20+ (rituximab, ocrelizumab) leukocytes, are approved for the treatment of multiple sclerosis. Thyroid autoimmunity is a common adverse effect of alemtuzumab treatment, Graves’ disease (GD) being the most prevalent manifestation. To date, thyroid autoimmunity events have not been reported with CD20-targeting monoclonal antibodies.

Case Report. A 59-year-old woman with primary progressive multiple sclerosis with no prior personal history of thyroid disease or autoimmunity, was diagnosed with GD 6 months following the first ocrelizumab infusion. She was asymptomatic and had no signs of ophthalmopathy. Due to the temporal association of GD diagnosis with ocrelizumab infusion, absence of symptoms and our experience with alemtuzumab-induced GD, we decided for an active surveillance strategy and antithyroid drugs were not started. She underwent spontaneous resolution of hyperthyroidism with thyroid-stimulating hormone (TSH) receptor antibodies (TRAb) negativity and a mild and transitory period of subclinical hypothyroidism, while she continued the biannually ocrelizumab administration schedule. To present date, she has maintained close clinical and biochemical surveillance with normal TSH, free thyroxine (fT4) and free triiodothyronine (fT3) levels and undetectable TRAb.

Conclusions. This is the first case of GD reported after ocrelizumab administration. The timing, onset and course of this case is similar to alemtuzumab-induced GD, usually interpreted as an “immune reconstitution syndrome”; however, ocrelizumab cell count depletion is inferior in severity, cell population affected and duration of depletion. This case highlights the importance of pre-screening and follow-up with thyroid function tests in patients treated with ocrelizumab. As a novel therapeutic antibody, further investigation is required to unravel the causes of thyroid autoimmunity.
Budget behaviour and cultural contingencies: case study in a Tunisian company
Authors: Dakhli Anissa 
Published: September 2021

Abstract

Background
Budgetary participation has a positive impact on a variety of emotional and behavioural responses. However, the review of empirical studies conducted in Tunisia reveals a low participation rate among operating managers in the budget control systems of their companies.

Research aims
The purpose of this study is to understand, from a contingency perspective, the practices of budgetary participation in Tunisian companies. It aims to explore forms of budgetary participation practised by Tunisian companies and examine to what extent Tunisian cultural variables explain these budgetary behaviours.

Methodology
A qualitative methodology based on a single case study was used. The data collected were the subject of a thematic content analysis.

Findings
The results show that the Tunisian companies have serious difficulties engaging in budgetary participation. Several factors hinder the implementation and operation of this budgetary practice. The primary factors include personality variables that, although interact with cultural values rooted in Tunisian society, create a psychological inconsistency between the ideal environment for the development and success of a participative approach and the environment of the Tunisian company.
About Sacubitril/Valsartan: A Clinically-Oriented Primer for Internists
Authors: Casian Mihnea , Munteanu Alice Elena 
Published: September 2021

Abstract
The medical therapy of heart failure (HF) has been traditionally based on inhibiting the main pathophysiologic mechanisms: the adrenergic and renin-angiotensin-aldosterone systems. Introducing the therapeutical triad of beta-blockers, angiotensin converting enzyme inhibitors and mineralocorticoid receptor antagonists in the treatment of HF patients almost 40 years ago marked an important step since they were not only addressing the symptoms of HF, but also the prognosis and life- expectancy of these patients. Although many discoveries have been made in the past years, no other therapeutic class was able to increase survival among HF patients, until recently, when th SA e benefits of modulating the natriuretic peptide system were brought to the attention of the scientific community. Increasing the levels of natriuretic peptides with Sacubitril/ Valsartan (SV) led to several benefits for the reduced ejection fraction HF population, including less long and short term complications, increased survival and a reduced symptom burden. As this article is being written, it is estimated that more than 2.8 million patients are being treated with SV(1). Therefore, SV is an important and validated therapy for HF patients and internists should be aware of its indications, benefits and management in clinical practice.
Protection of power transformers against the effect of magnetic storms
Authors: Mayer Daniel 
Published: September 2021

Abstract
In the operation of large-scale power systems for the long-distance transmission of large amounts of electricity, a number of cases have been reported in which anomalies in the Earth’s magnetosphere, referred to as geomagnetic storms, have caused a severe system collapse. Changes in the geomagnetic field cause a semi-saturating phenomenon, in which the high-voltage lines and especially the high-voltage windings of the power transformers of the system are overloaded with current and subsequently also thermally. The present article briefly explains the physical nature of magnetic storms and then describes a new device that either eliminates the possibility of a step-down power transformer accident or significantly reduces its effects on the system. The essence of this device are frequency filters, which are connected in parallel to the high-voltage windings of power transformers. At the beginning of a geomagnetic storm, the frequency filter is automatically connected to the system and is automatically disconnected when it subsides. The operation of frequency filters does not require human intervention, acquisition and operating costs are low and their integration into existing power systems is easy.

Published: September 2021

Catalyst optimization for enantioselective transformations has traditionally relied on empirical evaluation of catalyst properties. Although this approach has been successful in the past is it intrinsically limtied and inefficient. To address this problem, our laboratory has developed a fully informatics guided workflow to leverage the power of artificial intelligence (AI) and machine learning (ML) to accelerate the discovery and optimization any class of catalyst for any transformation. This approach is mechanistically agnostic, but also serves as a discovery platform to identify high performing catalysts that can be subsequently investigated by with physical organic methods to identify the origins of selectivity.

Published: September 2021

Авторы проводят анализ дискурса «образ будущего» в современной социально-политической мысли. Разделяя позицию З. Баумана о риторической манифестации власти о приватизации будущего, авторы обращают внимание на имманентно присущую природе политики функцию целеполагания, в том числе выработке и реализации коллективных целей, ориентированных на будущее. Анализируя молодежную политику в современной России, авторы приходят к выводу, что российское государство стремится адаптировать запросы молодых людей под собственные образы будущего великой и сильной державы, расставляя акценты на воспитание гражданственности и патриотизма. Авторы полагают, что для повышения эффективности государственного управления при разработке национальных проектов необходимо учитывать взгляд молодежи на будущее страны.
The authors analyze the discourse «the image of the future» in modern sociopolitical thought. Sharing the position of Z. Bauman on the rhetorical manifestation of the authorities about the privatization of the future, the authors pay attention to the goalsetting function inherent in the nature of politics, including the development and implementation of collective goals oriented towards the future. Analyzing the youth policy in modern Russia, the authors come to the conclusion that the Russian state seeks to adapt the needs of young people to its own images of the future of a great and strong power, placing emphasis on the education of citizenship and patriotism. The authors believe that in order to improve the efficiency of public administration, when developing national projects, it is necessary to take into account the view of young people on the future of the country.
