The effect of ambient humidity on the electrical conductive properties of α-Ga2O3 and α-Ga2O3/ε-Ga2O3 structures has been studied. Polymorphic Ga2O3 epitaxial layers were deposited by chloride vapor phase epitaxy on sapphire substrates. Pt and Pt/Ti were used as contacts. It was found that the Pt/α-Ga2O3/Pt and Pt/Ti/α-Ga2O3/ε-Ga2O3/Ti/Pt structures exhibit a high sensitivity of the current – voltage characteristics (I–V characteristics) to atmospheric humidity in the temperature range 25–100 °C. It was found that the effect of water vapor on the I–V characteristics of the structures is reversible and the most significant changes in the current in the samples are observed at a relative humidity RH ≥ 60%. With increasing temperature the effect of atmospheric humidity on the I–V characteristics decreases and disappears at T > 100 °C. The experimental results obtained are explained in terms of the Grottguss mechanism.

The possibility of using He+ ion implantation with an energy of 20 keV for modifying the domain structure and magnetic properties of CoPt films formed by electron beam evaporation with different compositions - Co0.45Pt0.55 and Co0.35Pt0.65 - has been investigated. For the irradiated CoPt samples of both compositions, a decrease in the coercivity (narrowing of the hysteresis loop on the magnetic field dependences of the Faraday angle and magnetization) with an increase in the He+ ion fluence from 2×1014 to 4×1014 cm−2 was found. In this case, the remanent magnetization of the Co0.35Pt0.65 films coincides with the value of saturation magnetization, while for Co0.45Pt0.55, a decrease in the remanent magnetization is observed.
Magnetic force microscopy has shown that for the Co0.45Pt0.55 alloy, with an increase in the ion fluence up to 3 × 1014 cm−2, the largest number of isolated circular domains (skyrmions) is formed, while for He+ irradiation with a fluence of 4×1014 cm−2 for Co0.35Pt0.65, in addition to isolated circular domains, 360-degree domain walls (1D skyrmions) are observed. At the same time, the study of CoPt films by the Mandelstam-Brillouin spectroscopy method revealed an increase in the shift between the Stokes and anti-Stokes components of the spectrum and thus a significant increase of the Dzyaloshinsky-Moriya interaction for the irradiated samples.
Simulation using the SRIM software showed that the applied ion irradiation causes the asymmetric mixing of Co and Pt atoms and thus, this may underlie the mechanism of the of the ion irradiation on magnetic properties and domain structure in CoPt films.

Published: December 2020

The calculations of electronic band structure of the cobaltite PrBaCo2O5+d for the content of oxygen near 5.5 have been performed using the first-principle PAW method. It has been shown that the semiconductor-metal transition near 5+d=5.5 is associated with the conversion of cobalt atoms in octahedral oxygen surrounding from high to low spin state and the similar atoms in pyramidal surrounding from the low to high spin state. The metal conductivity appears due to raising of the energy of pyramidal Co eg antibonding states. As a result these states turn up at the Fermi level thus defining the conductivity. The effect of oxygen content deviation from 5.5 on the band structure and conductivity has been studies. It is shown that the semiconductor-metal transition can be observed in the narrow range of 5+d below 5.5.

Authors: Burns David , Boyer Philip , Razmjou Helen , Richards Robin , Whyne Cari
Published: December 2020

Background

Physiotherapy is considered to be essential for the successful operative and nonoperative management of rotator cuff pathology; however, the extent to which patients adhere to assigned physiotherapy activities and how this impacts recovery is unknown.

Objective

The purpose of this study was to measure the rate and patterns of participation in physiotherapy for rotator cuff disorders, assess the dose response between physiotherapy activity and recovery, and explore patient factors predictive of physiotherapy participation.

Methods

We report a prospective longitudinal study of 42 patients undergoing physiotherapy for symptomatic rotator cuff pathology. The patients were issued a smartwatch that recorded inertial sensor data while they performed physiotherapy exercises both in the clinic and in the home setting. A machine learning approach was used to assess total physiotherapy participation from smartwatch inertial data. Primary outcomes were the Disabilities of the Arm Shoulder and Hand and numeric pain rating scale assessed every 4 weeks until 12 weeks follow-up. The relationships between participation, outcomes, and clinical patient variables were assessed in univariable analyses.

Results

Mean physiotherapy exercise participation in clinic and at home were 11 minutes per week and 33 minutes per week, respectively, with patients participating in physiotherapy on 41% of days assigned to treatment. Home physiotherapy participation decreased significantly over time (P=.03). There was a statistically significant and clinically meaningful relationship between cumulative physiotherapy participation and recovery demonstrated by pain scores at 8 weeks (P=.02) and 12 weeks (P=.05) and disability scores at 8 weeks (P=.04) and 12 weeks (P=.04). Low patient expectations and self-efficacy were associated with low rates of physiotherapy participation.

Conclusions

There was a low rate of participation in home shoulder physiotherapy exercise, and a statistically and clinically significant dose response of physiotherapy on treatment outcome in patients with rotator cuff pathology. The findings highlight the opportunity to develop novel methods and strategies to improve the participation in and efficacy of physiotherapy exercises for rotator cuff disorders.

Authors: MacIsaac Angela , Mushquash Aislin R , Mohammed Shakira , Grassia Elizabeth , Smith Savanah , Wekerle Christine
Published: December 2020

Background

The effects of adverse childhood experiences (ACEs) on mental health, self-regulatory capacities, and overall resilience are well-known. Given such effects, ACEs may play a role in how individuals adjust to challenges later in life. Of interest in this study is the transition to university, a time of heightened stress when adapting to circumstances is required and when those with ACEs may need additional in-the-moment support to exercise resilience. A smartphone app may provide a worthwhile and readily accessible medium for a resilience intervention, provided behavioral outcomes are adequately evaluated.

Objective

This study evaluates the impact of an innovative, smartphone app–based resilience intervention. The JoyPop app was designed to promote resilience through the use of self-regulatory skills such as emotion regulation and executive functioning. Among a sample of first-year undergraduate students, we explored whether use of the app would be associated with positive changes in resilience and related outcomes, and whether these benefits were influenced by level of childhood adversity.

Methods

Participants (N=156) were requested to use the JoyPop app for 4 weeks, at least twice daily. Changes in resilience, emotion regulation, executive functioning, and depression were assessed after 2 and 4 weeks of app usage using multilevel modeling.

Results

The sample of 156 participants included 123 females and 33 males, with a mean age of 19.02 years (SD 2.90). On average participants used the app on 20.43 of the possible 28 days (SD 7.14). App usage was associated with improvements in emotion regulation (χ21=44.46; P<.001), such that it improved by 0.25 points on the 18-point scale for each additional day of app usage, and symptoms of depression (χ21=25.12; P<.001), such that depression symptoms were reduced by .08 points on the 9-point scale with each additional day of app usage. An interaction between ACEs and days of app usage existed for emotion regulation, such that participants with more adversity evidenced a faster rate of change in emotion regulation (P=.02).

Conclusions

Results highlight that daily incorporation of an app-based resilience intervention can help youth who have experienced adversity to improve emotion regulation skills and experience reductions in depression. The JoyPop app represents an important step forward in the integration of resilience intervention research with a technology-based medium that provides in-the-moment support.

Do Newer Antidepressant Drugs Really Have Reduced Side Effects? Examining a Random “Real World” Sample of 300+ Receivers of Medications
Authors: Adams Nicholas Norman
Published: December 2020

Newer antidepressant drugs are frequently cited as having reduced side effect profiles to that of their older counterparts. However, recent studies have begun to dispute this claim, citing selective sampling, short clinical trials, and clinical trial environments as influencing reported outcomes. At present, little research on antidepressant side effects draws on RWD (Real-World Data). Despite this, interest in examining RWD samples for antidepressant drug side effects is increasing as of 2020. The reported study asked a random sample of 300+ individuals taking a variety of different antidepressant medications to complete online drug side effect self-report scales with previously high validity. Newer antidepressants belonging to the atypical antidepressant drug class were reported as having only slightly reduced side effects of weight gain compared with older SSRI-class medications. No reduced side effects of increased depression, anxiety, sexual dysfunction (SD), sleepiness, or suicidal ideation (SI) were found for the newer atypical-class medications vs older SSRI-class agents. Medication adherence did not differ significantly between SSRI and atypical classes. No evidence for reduced side effects was found for newer SSRI and atypical antidepressants vs older same-class drugs when comparing six new and old medications drawn from atypical and SSRI classes. However, atypical antidepressants were associated with increased use of adjunct medications to bolster primary treatment.
Modeling the Hydrological Characteristics of Hangar Watershed, Ethiopia
Authors: Galata Abdata
Published: December 2020

Modelling the hydrological characteristics of watershed is a method of
understanding behavior and simulating the water balance components of
watershed for planning and development of integrated water resources
management. The soil and water assessment tool (SWAT) physically based
hydrological modelling was used for modelling hydrologic characteristics
of the Hangar watershed. The data used for this study were digital
elevation model (DEM), land use land cover data, soil map,
climatological and hydrological data. The model calibrated and validated
using measured streamflow data of 13 years (1990-2002) and 9 years
(2003-2011) respectively including warm-up period. The SWAT model
performs well for both calibration (R2 = 0.87, NSE = 0.82 and PBIAS =
+1.4) and validation (R2 = 0.89, NSE = 0.88 and PBIAS = +1.2). The
sensitivity analysis, which was carried out using 18 SWAT parameters,
identified the 13 most sensitive parameters controlling the output
variable and with which goodness-of-fit was reached. The analysis
results indicated that the watershed receives around, 9.6%, 59.9%, and
30.5% precipitation during dry, wet and short rainy seasons
respectively. The received precipitation was lost by 9.6 %, 40.5%, and
41.3% in the form of evapotranspiration for each seasons
correspondingly. The surface runoff contribution to the Watershed were
3.8%, and 79.2% during dry and wet seasons respectively, whereas, it
contributes by 17.0% during short rainy seasons.

Resilience in agriculture: how can cap direct payments impact it?
Authors:   Lithuanian Institute of Agrarian Economics, Zickiene Agne
Published: December 2020

The increasing frequency and magnitude of adverse meteorological events together with the growing uncertainty in the upcoming future pose more and more challenges to agriculture. Therefore, the future sustainability of agriculture will increasingly depend on its resilience, i.e. the capacity to withstand various perturbations and to recover from them. The direct payment (DP) system of the EU Common agricultural policy (CAP) is the most financed EU support scheme for agriculture; however, research on its impact on the important phenomena of resilience is scarce and fragmented. In order to fill this gap, this paper offers an extensive overview of literature and a summarized list of factors that are mentioned most often as potentially influencing the agricultural resilience. Based on this, the possible impact of DP on agricultural resilience was analyzed. In this paper, it is argued that this impact is transferred mostly through changing farms’ financial capabilities as well as farmers’ attitudes and behavior, and is both positive and negative. Such phenomena as low crop insurance uptake and decrease in productivity may be due to the overcrowding effects of direct payments. These hypotheses are being tested in a survey, conducted in the meantime.

Published: December 2020

The clinical case of liver revascularization in a recipient using the technique of selective thrombolysis of the hepatic artery and its stenting at the arterial anastomosis site has been reported. The applied technique allowed a quick elimination of thrombosis and stenosis of the arterial anastomosis, providing a long-term effect, preventing more severe consequences for the recipient, and saving the liver graft. The presented case showed that the combined technique of endovascular intervention might be a good alternative to the reconstruction of arterial anastomosis by re-exploration and by liver retransplantation.

Authors: Prozorov S. A.
Published: December 2020

Introduction. Vascular complications after transplant nephrectomy are rather rare. The aim of this article is to analyze the effectiveness of the stent-graft implantation in the treatment of pseudoaneurysm after transplant nephrectomy. Clinical case. In the previous 23 years, a 50-year-old patient underwent 3 kidney transplantations from a cadaveric donor and 2 transplant nephrectomies. At 12 years after the left transplant nephrectomy he complained of abdominal pain and was admitted for a pulsating mass in his left pelvic region. Computed tomography angiography, ultrasonography, and arteriography were performed and showed a large pseudoaneurysm arising from the left external iliac artery. The stentgraft implantation solved the problem providing successful clinical and radiological results. Conclusion. Treatment options in this case were open or endovascular techniques. Surgical revision associated with high risk of complications. Endovascular treatment had the benefits of a minimally invasive approach with low blood loss.
PHENOMENON OF DEMIKHOV. In the Sklifosovsky Institute (1960–1986). C.N. Barnard and the first clinical heart transplantation (December 3, 1967). V.P. Demikhov and C.N. Barnard: touchpoints
Authors: Glyantsev S. P. , Gorelik B. M. , Werner A.
Published: December 2020

Having studied the available printed, visual, and verbal sources from Russia, South Africa, the USA, and Germany,we have identified and reviewed in the article the facts of face-to-face and correspondence communication betweenV.P. Demikhov, the "father" of experimental heart transplantation (Moscow, USSR), and C.N. Barnard, a pioneer ofclinical heart transplantation (Cape Town, South Africa). We have shown that C.N. Barnard mastered the heart surgerytechniques, including those under conditions of artificial circulation, in the USA in 1956-1958, and later improved themin his homeland both in clinic (heart surgery for cardiac defects), and in the experiment (heart transplantation). Themain events preceding the first world human heart transplant performed by C.N. Barnard on December 3, 1967, werehis trip to the United States in August 1967 to study immunosuppression techniques, and the kidney transplantationhe had performed in Cape Town in September, 1967. Prior to that time, C.N. Barnard had visited the USSR only once,in May 1960, as a delegate to the XXVII All-Union Congress of Surgeons. In the Soviet Union, he visited a number ofclinics dealing with heart surgery and tissue and organ transplantation, including the N.V. Sklifosovsky Institute forEmergency Medicine, where he met V.P. Demikhov, but C.N. Barnard could neither talk to him personally, nor watch hisoperations. In December 1967, V.P. Demikhov spoke with C.N. Barnard on the phone, but the conversation was highlyprofessional. This paper has shown different approaches of V.P. Demikhov and C.N. Barnard to the transplantationproblem: the Soviet surgeon paid more attention to the transplantation technique, meanwhile, the South African surgeonconsidered the solution of immunological problems to be the basis of success. Nevertheless, C.N. Barnard knew aboutV.P. Demikhov's scientific achievements and used some of them in his surgical practice. The authors have substantiatedthe interaction between V.P. Demikhov and C.N. Barnard as between an ideological mentor and a student (in a broadsense) rather than as a teacher and a student (in a narrow sense). Therefore, in a broad, philosophical sense, the Sovietsurgeon can be considered one of the inspirers of the world's first heart transplantation, which, in turn, proved that hisascetic work was not in vain.

Necrotizing soft tissue infection (NSTI) is an aggressive and rapidly spreading soft tissue infection that could be associated with high mortality. Early diagnosis can be challenging and so a high index of suspicion is needed. Bedside ultrasonography (USG) and computed tomography (CT) scan could be employed to aid in diagnosis.  The objective of this report is to describe the diagnostic process in a resource challenged setting and review the literature. We present an elderly patient with necrotizing fasciitis of the anterior abdominal wall as a complication of neglected strangulated Richter’s epigastric hernia that resulted in mortality.

Published: December 2020

Aggression is a behavior that intent to hurt others. Despite collective researches about aggression, there is a dearth in fully established psychosocial programs for the Children in Conflict with the Law (CICL) and evaluating program directed to aggressive behavior in the Philippines. Eight CICL housed in an institution under the supervision of the DSWD-Dasmariñas were the primary source of data. The study seeks to describe the pre-and-post mean scores of aggressions and determine the significant difference in aggression reduction before and after exposure to AMP. Employing the quasi-experimental design, the researchers administered the intervention and conducted repeated-measures to measure the effectiveness of AMP thru combined approaches of CBT-EFT in reducing their aggression level. Findings revealed that their aggression in the areas of physically aggressive responses, and verbally aggressive reactions were diminished after participating in the AMP, with the inclusion of counseling sessions in addressing problematic concerns related to aggressive behavior.

examen de las bóvedas y cúpulas de la Edad Moderna en el monasterio de San Julián de Samos: nuevos lenguajes arquitectónicos, viejos sistemas de cubrimiento
Authors: López Salas Estefanía
Published: December 2020

Basándonos en un exhaustivo análisis in situ de la arquitectura construida en el monasterio de San Julián de Samos (Lugo, España) durante los siglos XVII y XVIII, este artículo explora la variabilidad de las estructuras utilizadas para cubrir las nuevas dependencias y su ausencia clara de relación con las corrientes estilísticas predominantes y con los ejemplos construidos, en ese mismo periodo, en otras casas monacales gallegas. Nuestro objetivo último es entender las razones que están detrás de la utilización de viejos sistemas constructivos en un momento de introducción de unos nuevos planteamientos artísticos y en las que, entre otras cuestiones, el papel del monje fray Pedro Martínez, del monasterio burgalés de San Pedro de Cardeña, se revela como factor clave.
proceso constructivo de la Capilla del Lignum Crucis del Real Monasterio de Santo Toribio de Liébana (Cantabria)
Authors: Losada Varea Celestina
Published: December 2020

La documentación que aportamos permite acotar en dos fases el proceso constructivo de la Cámara Santa (o Capilla del Lignum Crucis) del Real Monasterio de Santo Toribio en Liébana (Cantabria). Tras un intento frustrado por parte de los Duques del Infantado (1632), las obras se iniciaron en 1675 bajo el patrocinio del X Almirante de Castilla. Su construcción definitiva a cargo del arquitecto vizcaíno Juan Bautista de Arbaiza (1718-1721), transformó la obra ya iniciada en un espacio barroco magnificado por la presencia de uno de los escasos cimborrios octogonales pétreos existentes en la España del siglo XVIII.
Faux Primitifs flamands dans les collections espagnoles: œuvres publiées, œuvres inédites (Collections d’Espagne III ?)
Authors: Martens Didier , Velasco Gonzàlez Alberto , Dimov Alexandre , Zdanov Sacha
Published: December 2020

La redécouverte de la peinture flamande des xve et xvie siècles a suscité, à partir des années 1890, une production à grande échelle de faux Primitifs flamands. Dans certains cas, il s'agit d'œuvres réalisées sur un support moderne, dans d'autres, de tableaux anciens restaurés abusivement. Un certain nombre de ces faux Primitifs flamands se sont retrouvés dans des collections espagnoles. Plusieurs ont été reproduits comme des œuvres authentiques, flamandes ou hispano-flamandes, par des auteurs aussi réputés que Chandler Post, Jacques Lavalleye et Elisa Bermejo. Parmi les falsifications inédites étudiées dans le présent article, certaines peuvent être attribuées au restaurateur-faussaire belge Joseph Van der Veken ou au mystérieux 'Faussaire de Valls Marín'.
San Román de Hornija 1908: primeros intentos de venta de la tabla central del retablo del arzobispo don Sancho de Rojas
Authors: Lorenzo Arribas Josemi , Pérez Martín Sergio
Published: December 2020

Manuel Gómez-Moreno llegó a San Román de Hornija en 1908 y supo apreciar la importancia de las tablas pintadas que se conservaban en la capilla del cementerio y otra, la central, ya trasladada al palacio episcopal de Zamora para ser vendida. Alarmado, escribió al senador Elías Tormo, que denunció públicamente el caso. Recorremos los avatares de este conjunto a partir de la correspondencia de Gómez-Moreno y se recogen las primeras referencias a la tabla central (1883), con el premonitorio aviso de Manuel Bartolomé Cossío, que pedía ya su traslado al Museo del Prado, como acabó ocurriendo en 1928.
linaje del cardenal don Juan de Torquemada: poder económico y promoción artística
Authors: Domínguez Casas Rafael
Published: December 2020

El Cardenal Torquemada († 1468) fue una figura crucial en la conexión entre el arte italiano y el nórdico. En su excepcional labor como embajador, teólogo y reformador, recibió apoyo económico de su tío Garci Fernández de Torquemada, un rico mercader que tenía contactos comerciales en Flandes, Francia e Italia. Resultan infundados los rumores sobre un posible trasfondo judeoconverso del cardenal difundidos por el cronista Hernando del Pulgar.

Purpose of research. The aim of the study is to evaluate changes in density, Agatston score, Volume and Mass scores of coronary calcium at different scanning parameters using phantom measurement.

Materials and methods. 8 1-ml insulin syringes filled with potassium hydroorthophosphate solution of different densities were used in the study. The syringes were placed at regular intervals into two phantoms: type 1 phantom – container filled with water; type 2 phantom – Chest Phantom N1 “LUNGMAN”. The phantoms were scanned with a Philips Ingenuity Elite CT 128 scanner using protocols with different voltages (80, 100, 120, 140 kV), amperage (27–45, 166, 330–400 mA), and slice thickness (0.625, 1, 2.5, 3 mm).

Results. Density and Agatston indexes were obtained at different scanning parameters (voltage, amperage, slice thickness) for different factors of calcification density in both phantoms. The results are presented as a table with mean density values, standard deviation (SD), Agatston score of coronary calcium, and scanning parameters.

Conclusion. The study demonstrates the influence of various scanning parameters on coronary artery calcium scoring results. The obtained information can be used in practice for more accurate quantification of coronary artery calcium, regardless of the scanning parameters.
