Efficient analytical method for the shielding effectiveness of an apertured enclosure based on the BLT equation
Authors: Gong Yanfei , Li Yujie , Jiang Luhang 
Published: June 2020

An efficient analytical method based on the Baum–Liu–Tesche (BLT) equation has been developed for predicting the shielding effectiveness (SE) of an apertured enclosure excited by an external plane wave. First, the equivalent circuit and the signal flow graph are constructed, which helps understand the energy transmission of the enclosure. Then, the SE is obtained by using the generalised BLT equation, and the proposed analytical method is employed to analyse the effect of various parameters on the SE. Finally, the analytical method is extended to handle the enclosure with an aperture array, an enclosure with apertures at the opposing walls and two cascaded enclosures. The analytical method has been successfully verified by the CST over a wide frequency band of 0–3.0 GHz, which consumes less time than conventional numerical methods. Besides, whatever the condition of the enclosure or the aperture is, the analytical method can predict the SE and higher‐order modes at higher frequencies accurately.
Efficient method for the shielding effectiveness of an enclosure with electrically large apertures based on the Cohn model and mirror procedure
Authors: Gong Yanfei , Jiang Luhang , Li Yujie 
Published: June 2020

An efficient analytical method based on the Cohn model and mirror procedure is proposed for the prediction of the shielding effectiveness (SE) of a rectangular enclosure with electrically large apertures. Firstly, the coupled electromagnetic fields are represented by the equivalent dipole moments located at the centre of the aperture according to the Cohn model, where the dipole moments can be calculated based on the mirror procedure. Then, the vector potentials can be obtained through the relation between the dipole moments and the current distribution. Finally, the total electric fields are obtained by using the vector potentials, thus the SE and most of the resonant modes can be predicted accurately and fast. The SE results which have been verified by the CST over a wide frequency band of 0.01–3.0 GHz show that the proposed method is effective in handling the enclosure with electrically large apertures, including the multiple apertures arranged in different ways and hybrid apertures in different shapes and dimensions.

Zusammenfassung
Hintergrund Die Richtungslokalisation ist eine Teilleistung der zentralen auditiven Verarbeitung. Es wurde der Frage nachgegangen, ob das Tragen von Hörgeräten die Lokalisationsfähigkeit von nichtsprachlichen Stimuli bei schwerhörigen Schulkindern unterstützt.
Patienten und Methoden 20 Kinder (7–17 Jahre) mit einer beidseitigen, symmetrischen, mittelgradigen peripheren Schallempfindungsschwerhörigkeit (WHO-Grad 2) wurden im Freifeld mit und ohne Hinter-dem-Ohr-Hörgeräte (HG) untersucht. Alle Probanden trugen HG mit individuellen Passstücken. Die Aufgabe war, die Position überschwelliger akustischer Signale im Freifeld mithilfe eines Laserpointers innerhalb einer halbkreisförmigen Anordnung von 45 Lautsprechern anzuzeigen. Es wurden jeweils tief- und hochfrequente Stimuli getestet, um den Einfluss von interauralen Zeit- und Pegelunterschieden auf die Verarbeitung unterscheiden zu können. Die Ergebnisse wurden mit denen normalhörender Kinder verglichen.
Ergebnisse In unserem Testaufbau gab es keinen signifikanten Unterschied zwischen der Messung mit und ohne HG, weder für die unterschiedlichen Frequenzbänder noch für die unterschiedlichen getesteten Positionen. Die absolute Abweichung der schwerhörigen Kinder war um 3–4° frontal und 5–11° lateral schlechter als die hörgesunder Kinder. Wie auch normalhörende Schulkinder konnten die schwerhörigen Schulkinder frontale Positionen signifikant besser lokalisieren als laterale. Ebenso zeigte sich keine Altersentwicklung der Lokalisationsfähigkeit.
Schlussfolgerung In unserem Testaufbau konnten HG die schlechtere Lokalisationsfähigkeit schwerhöriger Kinder nicht ausgleichen.

AbstractAs more patients undergo total knee arthroplasty (TKA) each year, and the average age of patients gets younger, the patients are generally more active requiring a greater physiological demand and increasing range of motion on the prosthesis than the previous patients. However, there is no consensus on the optimal TKA tibial bearing design. We performed this systematic review to compare the clinical differences between mobile and fixed bearing constructs used in contemporary TKA. We searched PubMed, EMBASE, and Cochrane Library databases, identifying 515 total publications, including 17 randomized controlled trials (RCTs). A meta-analysis was performed, while the quality and bias of the evidence were rated according to the Grading of Recommendations Assessment Development and Evaluation (GRADE) guidelines and the Cochrane Database questionnaire. The meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Seventeen studies were included, with a total of 1505 knees receiving a mobile bearing TKA and 1550 knees receiving a fixed bearing TKA. The meta-analysis compared clinical outcomes between mobile bearing (MB)-TKA and fixed bearing (FB)-TKA using postoperative Knee Society Score, postoperative ROM, and survivorship and showed that there was a distinct difference in Knee Society Score between the mobile-bearing and fixed-bearing groups (overall standardized mean difference = 1.38; 95% confidence interval (CI): 0.50–2.25; p = 0.002; I2 = 60%). Patients treated with mobile-bearing prostheses were more likely to report good or excellent range of motion results (overall standardized mean difference = 2.06; 95% CI: 0.65–3.47; p = 0.004). No difference in implant survivorship or reoperation rate were identified. The fixed-bearing and mobile-bearing TKA designs are both capable of producing excellent long-term results with excellent clinical outcomes if properly implanted; however, the mobile-bearing TKA have superiority in mid- to long-term clinical results. Trial registration number for PROSPERO was CRD42019126402.

Published: June 2020

Introduction Dyspnea is often encountered in terminally ill cancer patients and is attributed to multiple factors. The use of fan-on-face therapy is a nonpharmacologic adjunct treatment for adult cancer patients suffering from dyspnea at the end-of-life. This study was done to determine if the use of fan-on-face therapy in addition to the standard of care treatment indeed confers clinical benefit to terminally ill adult cancer patients with dyspnea.
Materials and Methods A meta-analysis of randomized controlled trials on the use of fan-on-face therapy in relieving dyspnea among terminally ill adult cancer patients was performed. A computerized search was done in MEDLINE, NICE, CENTRAL, Science Direct, and Google Scholar for relevant articles. Other publications were searched, and authors were contacted for additional information. The primary outcome measure was the mean change in dyspnea score, determined by the Modified Borg Scale, Numeric Rating Scale, or Visual Analog Scale. The secondary outcome was the post-intervention mean change in respiratory rate (RR).
Results Four eligible randomized controlled trials of low to moderate risk of bias employed a total of 139 cancer patients. Fan-on-face therapy was effective in decreasing mean dyspnea scores (standard mean difference = −1.81, 95% confidence interval [CI]: −3.12, −0.50, p < 0.00001, I2 93%) and improving mean change in RR (mean difference = −0.91, 95% CI: −1.68, −0.15; p = 0.001, I2 = 81%) versus control.
Conclusion Fan-on-face therapy, as an adjunct to standard of care, is effective in alleviating dyspnea among adult cancer patients during the end of life.
“A great crisis of identification and understanding of reality”
Authors: Nigri Lucia 
Published: June 2020

Abstract
Shakespeare’s plays proved crucial in Strehler’s career in many respects as they provided ‘narratives’ through which he could interpret the sequence of cultural, political, and social crises that he acknowledged, experienced personally, and more or less directly addressed in his own theatre. This chapter explores how, through specific Shakespearean plays, these crises – which were both individual and collective – raised in Strehler questions on the nature of history. It also explores Strehler’s interrogation of the role of man in a world dominated by monotonous and nonsensical power games from the perspective of a cyclic view of history. Strehler’s encounter with Shakespeare is examined through his own writings as well as reviews and other related material. This constitutes a second-level focus mapping onto the role of different types of narratives in our reconstruction of Strehler’s own dynamic understanding of Italy within the international context over a time-span of thirty years.

AbstractThis study investigated the effect of the odors generated by the glycine/glucose Maillard reaction and the potent odorants 2,3-dimethylpyrazine (3DP) and 2,5-dimethyl-4-hydroxy-3(2H)-furanone (DMHF) on the human mood and integrative physiological activity. The score of certain subjective moods, especially anger-hostility, and tension-anxiety were decreased significantly after inhalation of the Maillard reaction sample and DMHF, and fatigue-inertia mood was also significantly decreased by DMHF, suggesting a sedative effect of these odors on mood, while 3DP had no effect. Miosis rate and fingertip temperature increased significantly following inhalation of the odor from the Maillard reaction sample and both potent odorants, suggesting that the parasympathetic nervous system dominates through suppression of the sympathetic activity. The physiological relaxing effect of these odors was also confirmed by decreased flicker frequency value and decreased oxyhemoglobin in the prefrontal cortex.

Using ab initio electronic structure methods, such as the coupled cluster and configuration interaction ones with small-core relativistic energy-consistent pseudopotentials and large Gaussian basis sets, we calculate potential energy curves for the ground and 41 excited electronic states, and electric dipole transition moments between them. We show that alkaline-earth molecular ions, despite their apparently simple structure with only three valence electrons, are challenging for state-of-the-art quantum chemistry methods due to their multireference nature and high density of states. Finally, we calculate and analyze Franck–Condon factors governing the photoionization of ground-state Sr2 molecules into

Eden growth models for flat clathrin lattices with vacancies

Published: June 2020

Abstract
Clathrin-mediated endocytosis is one of the major pathways by which cells internalise cargo molecules. Recently it has been shown that clathrin triskelia can first assemble as flat lattices before the membrane starts to bend. However, for fully assembled clathrin lattices high energetic and topological barriers exist for the flat-to-curved transition. Here we explore the possibility that flat clathrin lattices grow with vacancies that are not visible in traditional imaging techniques but would lower these barriers. We identify the Eden model for cluster growth as the most appropriate modeling framework and systematically derive the four possible variants that result from the specific architecture of the clathrin triskelion. Our computer simulations show that the different models lead to clear differences in the statistical distributions of cluster shapes and densities. Experimental results from electron microscopy and correlative light microscopy provide first indications for the model variants with a moderate level of lattice vacancies.

AbstractDespite the positive achievements attained, the treatment of male urethral strictures and hypospadiases still remains a challenge, particularly in cases of severe urethral defects. Complications and the need for additional interventions in such cases are common. Also, shortage of autologous tissue for graft harvesting and significant morbidity in the location of harvesting present problems and often lead to staged treatment. Tissue engineering provides a promising alternative to the current sources of grafts for urethroplasty. Since the first experiments in urethral substitution with tissue engineered grafts, this topic in regenerative medicine has grown remarkably, as many different types of tissue-engineered grafts and approaches in graft design have been suggested and testedin vivo. However, there have been only a few clinical trials of tissue-engineered grafts in urethral substitution, involving hardly more than a hundred patients overall. This indicates that the topic is still in its inception, and the search for the best graft design is continuing. The current review focuses on the state of the art in urethral regeneration with tissue engineering technology. It gives a comprehensive overview of the components of the tissue-engineered graft and an overview of the steps in graft development. Different cell sources, types of scaffolds, assembling approaches, options for vascularization enhancement and preclinical models are considered.
Digital environment, information systems and robotics: an absolute benefit or a new economic and political threat?
Authors: Botasheva A K , Anufrienko S V , Andish I B , Yefimova O V , Dyakonova M A 
Published: June 2020

Abstract
The introduction of new technologies into all spheres of human activity is rightly perceived by the scientific community as a qualitative leap in the development of human civilization. The effect of the introduction of information achievements, breakthrough technologies and communications, the spread of electronic data exchange, digitalization of the environment, etc. contributes not only to the growth of interdependence of the world economy, but also to the rapid improvement of the life quality. Therefore, the accepted set of values defines the central role of new technologies, which are often considered an absolute good. But the authors wonder whether this is an absolute good, or whether behind the facade of the actively developing process of exploiting the world and expanding science and technology into all types of human activity there is a fundamental change in the means of production and ways of human exploitation. The authors also conclude that the digitalization of the urban environment, appearance of autopilots and navigation systems, development of modern IT and nano-technologies, improvement of communication and production technologies open the questions not only of a military, but of an economic and political nature as well. The pursuit of technological efficiency does not take into account the “human dimension”, and the humanistic and sociocultural meaning of many technological achievements gets lost.

Stocks of organic substance in post-agrogenic lands in Leningrad region
Authors: Danilov D A , Navalikhin S V , Vayman A A 
Published: June 2020

Abstract
We have analysed factors affecting the formation of organic matter stocks in sod-podzolic soils and post-agrogenic lands in the south-western part of the Leningrad region. There are many factors influencing the process of humus formation, which does not allow to reliably simulate the process of transformation of organic residues and the accumulation of humus in areas previously used for agricultural production. There is a connection in the differences in the specific density of the soil and the unequal content of humus in the genetic horizons of fallow soil compared to the arable layer of the field, where these horizons are mixed into a homogeneous mass. The data obtained show a high correlation between the humus content in the former arable horizon of soil with a clay fraction and pHKCI. At different successional stages of accumulation of organic matter in post-agrogenic lands is not the same, as the formation of different species composition of vegetation makes adjustments to this process. When determining humus stock in post-agrogenic lands, an error can reach to 30%. The main reason is the differences in the specific density of the soil and the unequal content of humus in the genetic horizons of fallow soil compared to the arable layer of the field, where these horizons are mixed into a homogeneous mass. The conclusion was made about different methods of soil sampling from arable lands and from post-agrogenic lands.

Published: June 2020

Abstract
The article deals with theoretical and experimental studies of oily industrial wastewater flotation treatment using a saturator and vortex mixing devices (VMD) for preparing a water-air mixture. The use of VMD allows, in comparison with the saturator, to improve the efficiency of oil product removal on the flotator by 5-7% due to the greater gas saturation of the flotation volume. The energy consumption for preparing the water-air mixture in vortex mixers was on 8–10% lower than in flotation plants using a saturator.
Climate control in road-building machinery

Published: June 2020

Abstract
Climate control is an advanced air conditioning system that allows controlling the temperature in the machinery cabin more effectively in any weather conditions. Today, almost all new road-building machinery is equipped with this system. This system allows adapting the temperature in the cabin according to your needs more effectively. Climate control allows controlling the climate in the cabin regardless of the weather conditions outside the machine. Climate control works just like home air conditioners, thanks to the automatic control of the heating, ventilation and air conditioning systems. With the help of electronics, the temperature is automatically maintained at the level set by the driver. This system is necessary not only to maintain a stable temperature in the cab, but also to maintain the efficiency and concentration of the driver. However, there is no air conditioning system in the old road construction machines. In the Republic of Sakha (Yakutia) the material and technological foundations in many road enterprises are outdated for now. And in order to keep the driver operating and protect his health, this article discusses the possibility to equip road-building machinery with climate control. THE Volvo BL61B forklift was chosen as an example. This machine initially lacked a climate control system, but thanks to a temperature control device, it was possible to achieve the optimum temperature in the cabin.
Improving the Fire-fighting Design of Silencers

Published: June 2020

Abstract
This paper presents fire-fighting design of silencer formed by stepped partitions. Providing the distance between the partitions not exceeding a quarter of the wavelengths and forming the set of ducts with alternating expansions and narrowings create the possibilities for noise reduction and spark arresting. Slit silencer model testing on the stand contained doubled reverberant chambers with removable elements and diaphragm as well as on the stand with internal combustion chamber demonstrates the following: noise reduction is not less than 7.5 dB in a wide frequency range; pressure losses are not more than 120 Pa; sparks don’t pass. Correcting the silencer geometry allows forming the devices which acoustic and aerodynamic characteristics are similar to the characteristics of standard plate silencers. Calculating data show the dimensions of single and double silencer, ensuring spark arresting and requirement noise reduction in a gas flue.
