Context.BINGO (Baryon Acoustic Oscillations from Integrated Neutral Gas Observations) is a radio telescope designed to survey from 980 MHz to 1260 MHz, observe the neutral hydrogen (H I) 21 cm line, and detect the baryon acoustic oscillation signal with the intensity mapping technique. Here we present our method for generating mock maps of the 21 cm intensity mapping signal that cover the BINGO frequency range and related test results.Aims.We would like to employN-body simulations to generate mock 21 cm intensity maps for BINGO and study the information contained in 21 cm intensity mapping observations about structure formation, H Idistribution and H Imass-halo mass relation.Methods.We fit an H Imass-halo mass relation from the ELUCID semianalytical galaxy catalog and applied it to the Horizen Run 4 halo catalog to generate the 21 cm mock map, which is called HOD. We also applied the abundance-matching method and matched the Horizen Run 4 galaxy catalog with the H Imass function measured from ALFALFA, to generate the 21 cm mock map, which is called HAM.Results.We studied the angular power spectrum of the mock maps and the corresponding pixel histogram. The comparison of two different mock map generation methods (HOD and HAM) is presented. We provide the fitting formula of ΩHi, H Ibias, and the lognormal fitting parameter of the maps, which can be used to generate similar maps. We discuss the possibility of measuring ΩHiand H Ibias by comparing the angular power spectrum of the mock maps and the theoretical calculation. We also discuss the redshift space distortion effect, the nonlinear effect, and the bin size effect in the mock map.Conclusions.By comparing the angular power spectrum measured from two different types of mock maps and the theoretical calculation, we find that the theoretical calculation can only fit the mock result at large scales. At small scales, neither the linear calculation nor the halofit nonlinear calculation can provide an accurate fitting, which reflects our poor understanding of the nonlinear distribution of H Iand its scale-dependent bias. We have found that the bias is highly sensitive to the method of populating H Iin halos, which also means that we can place constraints on the H Idistribution in halos by observing 21 cm intensity mapping. We also illustrate that only with thin frequency bins (such as 2 MHz), we can discriminate the Finger-of-God effect. All of our investigations using mocks provide useful guidance for our expectation of BINGO experiments and other 21 cm intensity mapping experiments.
Which Milky Way masses are consistent with the slightly declining 5–25 kpc rotation curve?

Context. Discoveries of extended rotation curves have suggested that spiral galaxy halos contain dark matter. This has led to many studies that estimated the total mass of the Galaxy, mostly using the Navarro, Frenk, and White (NFW) density profile.
Aims. We determine the effect that the choice of the dark matter profile has on the predicted values of extrapolated total masses.
Methods. We considered a recently reported Milky Way (MW) rotation curve, first because of its unprecedented accuracy, and second because the Galactic disk appears to be least affected by past major mergers that have fully reshaped the initial disk.
Results. We find that the use of an NFW profile (or its generalized form, gNFW) to calculate the dark-matter contribution to the MW rotation curve generates apparently inconsistent results such as an increase in baryonic mass that leads to an increase in dark matter mass. Furthermore, we find that NFW and gNFW profiles narrow the total mass range, leading to a possible methodological bias particularly against low MW masses. Using the Einasto profile, which is better suited to represent cold dark matter halos, we finally found that the slightly decreasing rotation curve of the MW favors a total mass that can be as low as 2.6 × 1011 M⊙, disregarding any other dynamical tracers farther out in the MW. This is inconsistent with values higher than 18 × 1011 M⊙ for any type of cold dark matter halo profiles under the assumption that stars and gas do not affect the predicted dark matter distribution in the MW.
Conclusions. This methodological paper encourages the use of the Einasto profile to characterize rotation curves with the aim of evaluating their total masses.

Context.The spectral energy distribution (SED) in the millimetre to centimetre range is an extremely useful tool for characterising the dust in protostellar envelopes as well as free-free emission from the protostar and outflow. Actually, the evolutionary status of solar-type protostars is often based on their SED in the near-infrared to millimetre range. In addition, the presence or absence of free-free emission can be considered an indicator of the source evolutionary stage (Class 0/I versus Class II/III). While many studies have been carried out towards low- and high-mass protostars, little exists so far about solar-type protostars in high-mass star-forming regions, which are likely to be representatives of the conditions where the Solar System was born.Aims.In this work, we focus on the embedded solar-type protostars in the Orion Molecular Cloud (OMC) 2 and 3 filaments, which are bounded by nearby HII regions and which are, therefore, potentially affected by the high-UV illumination of the nearby OB stars. We use various dust parameters to understand whether the small-scale structure (≤1000 au) and the evolutionary status of these solar-type protostars are affected by the nearby HII regions, as is the case for the large-scale (≤104au) gas chemical composition.Methods.We used the Atacama Large (sub-)Millimeter Array (ALMA) in the 1.3 mm band (246.2 GHz) to image the continuum of 16 young (Class 0/I) OMC-2/3 solar-type protostars, with an angular resolution of 0.25″ (100 au). We completed our data with archival data from the ALMA and VLA VANDAM survey of Orion Protostars at 333 and 32.9 GHz, respectively, to construct the dust SED and extract the dust temperature, the dust emissivity spectral index, the envelope plus disk mass of the sources and to assess whether free-free emission is contaminating their dust SED in the centimetre range.Results.From the millimetre to centimetre range dust SED, we found low dust emissivity spectral indexes (β< 1) for the majority of our source sample and free-free emission towards only 5 of the 16 sample sources. We were also able to confirm or correct the evolutionary status of the source sample reported in the literature. Finally, we did not find any dependence of the source dust parameters on their location in the OMC-2/3 filament.Conclusions.Our results show that the small-scale dust properties of the embedded OMC-2/3 protostars are not affected by the high-UV illumination from the nearby HII regions and that the formation of protostars likely takes place simultaneously throughout the filament.

Published: July 2021

The article presents the results of the study to determine the predictors of the formation and development of personal identity of older preschool children. The conceptual basis of the study is the assumption that the formation of triangulatory relations internalized in the personality structure of maternal and paternal objects is an important prerequisite for the development of a holistic, stable, differentiated personality. The purpose: to highlight the results of empirical analysis of features and to determine the factors of formation and development of personal identity of older preschool children.Methods: biographical, semi-structured interview, analysis of family narratives; test of M. Kuhn and T. McPartland “Who I am?”, “Three trees”, “Compose a fairy tale”; H. Olson, J. Portner, I. Lavi “FASES-3”, “Interaction of parents and the child” of I. Markovska; E. Eidemiller’s “Analysis of Family Interaction”; “Scale of rejection of the child in the family” of A. Barkan; content analysis; methods of mathematical statistics SPSS-17. As a result of a factor analysis parameters of the family system, identification with the maternal or paternal object, four factors were identified: ability to triangulatory relations, stability/instability of personal identity of older preschool children, neutral selfattitude, factor of prerequisites for the formation of personal identity.Thus, in the course of the study it was determined that the formation of personal identity of a child of older preschool age is determined by the correlation between the place that the child occupies in the system of human relationships, and above all in the system of family relationships, and psychological features which have already been formed.
The method of observing the student’s behavior in the educational environment
Authors: Cristea Pleşan Niculeta 
Published: July 2021

This paper aims to highlight the efficiency of using the method of observing student behavior in the educational environment. Observation is one of the most widely used research methods in the social sciences. The characteristics aimed at constructing the instrument were: accuracy, focus, duration of observation, awareness of the presence of the observer, the level of information of the subject. In order to observe the student’s behavior in the school environment, the observation grid with standardized answers was designed on the Likert scale (scale from 1 to 10), following the degree of expression of the described behavioral manifestations.
The observation grid of the student’s behavior in the school environment aims at supervising 4 dimensions (each with 5 items: observable behaviors): interest in school activities, organization of activity / punctuality in the school environment, resistance to intellectual effort, socio-affective relationships.
Following the application of the research tool, depending on the scores obtained, it is recommended the targeted psycho-pedagogical intervention at the level of the deficient dimension / behaviors, as well as the monitoring of the results through the periodic application.

Published: July 2021

AbstractThe purpose of the study was to evaluate the influence of changes in ankle- and knee-joint angles on force steadiness and the discharge characteristics of motor units (MU) in soleus when the plantar flexors performed steady isometric contractions. Submaximal contractions (5, 10, 20, and 40% of maximum) were performed at two ankle angles (75° and 105°) and two knee angles (120° and 180°) by 14 young adults. The coefficient of variation of force decreased as the target force increased from 5 to 20% of maximal force, then remained unaltered at 40%. Independently of knee angle, the coefficient of variation for force at the ankle angle of 75° (long length) was always less (p<0.05) than that at 105° (shorter length). Mean discharge rate, discharge variability, and variability in neural activation of soleus motor units were less (p<0.05) at the 75° angle than at 105°. It was not possible to record MUs from medial gastrocnemius at the knee angle of 120° due to its minimal activation. The changes in knee-joint angle did not influence any of the outcome measures. The findings underscore the dominant role of the soleus muscle in the control of submaximal forces produced by the plantar flexor muscles.

Published: July 2021

ZusammenfassungSeit Jahren gilt die feuchte Wundbehandlung als Standard in der Wundversorgung. Obwohl dieser Grundsatz allgemein akzeptiert ist, ist die Evidenz schon für dieses Dogma überschaubar. Die Industrie bietet auf diesem Grundsatz eine Vielzahl von Produkten zur Wundversorgung an, deren Überlegenheit gegenüber anderen Produkten auf evidenzbasierter Grundlage oft nicht gegeben ist.Ziel war es, in einer Klinikgruppe das Sortiment unter hauptsächlich einkaufspolitischen Kriterien zu straffen und zu häufige, unbegründete Therapiewechsel zu vermeiden. Daraus ergab sich die Aufgabe, sich nach Möglichkeit auf wenige Hersteller zu begrenzen.Um die Akzeptanz und die Gründe für alle Anwender im Prozess transparent zu gestalten, wurden diese über eine strukturierte Abfrage für das Thema sensibilisiert und mitgenommen. Als Ergebnis ist ein kleines, sehr straffes Kontingent in der Wundversorgung mit hoher Anwenderakzeptanz entstanden. Hierdurch lassen sich im Einkauf deutliche Kosteneinsparungen realisieren.

Published: July 2021

Abstract
Introduction Diabetes mellitus is a metabolic disease associated with a rise in the level of blood glucose. Individuals with diabetes mellitus are more likely to develop hearing loss, tinnitus, and dizziness due to macro- and microvascular complications. The extent to which auditory and vestibular functions are impaired in individuals with type-2 diabetes mellitus is still under debate.
Objective To systematically review studies focusing on auditory and vestibular functions in individuals with type-2 diabetes mellitus.
Data Synthesis A search was conducted in the PubMed, MedlinePlus, Ingenta Connect and Google Scholar databases for articles published until June 2019. A total of 15,980 articles were primarily retrieved, 33 of which were shortlisted based on the inclusion criteria set by the investigators for the systematic review. Out of 33 full-length articles, 26 evaluated the functioning of the auditory system, while 7 evaluated the functioning of the vestibular system. Most studies related to auditory functioning reported a significant effect of type-2 diabetes mellitus on the peripheral auditory system, whereas studies on vestibular functioning reported no significant effect of diabetes mellitus on the functioning of the peripheral vestibular end-organ.
Conclusion Overall, the results of various audiological and peripheral vestibular tests reveal distinctive peripheral and/or central auditory and vestibular end-organ impairments in individuals with type-2 diabetes mellitus.
Acute Colonic Pseudo-obstruction and Volvulus: Pathophysiology, Evaluation, and Treatment
Authors: Underhill Joshua , Munding Emily , Hayden Dana 
Published: July 2021

AbstractAcute colonic pseudo-obstruction (ACPO) and volvulus are two disease processes that affect the colon causing abdominal distension and may necessitate operation intervention. ACPO may be associated with multiple comorbidities, infectious diseases, and cardiac dysfunction. It may be treated with conservative management including endoscopic decompression or neostigmine. If the distension is not addressed, high mortality may result if peritonitis develops. Volvulus most commonly occurs in the sigmoid colon or cecum. If left-sided, endoscopic decompression may resolve the obstruction if detorsion is successful, although sigmoid colectomy should be performed during the admission. If cecal volvulus is identified, right hemicolectomy should be performed.
Sudden Cardiac Death in the General Population: Can We Improve Risk Stratification and Prevention?
Authors: Murray Gary L. , Colombo Joseph 
Published: July 2021

AbstractA total of 15 to 20% of deaths worldwide are sudden (within 1 hour of symptom onset). Our ability to predict and prevent sudden cardiac death (SCD) in the general population, in which 85% have no known organic heart disease (OHD) or stable OHD with left ventricular ejection fraction >40%, is limited to poor. The purpose of this commentary is to suggest a new approach to SCD in this population. Oxidative stress is a common thread in development and progression of the major cardiac diseases associated with SCD. It has a profound adverse effect upon heart rate variability (HRV), sympathetic tone (S), and parasympathetic tone (P). Recently, developed technology finally has allowed accurate measures of S and P. Using this technique, the general population can be screened, those at risk for SCD can be identified with a higher degree of success, and preventative measures instituted. For example, in 133 geriatric type 2 diabetics with S and/or P abnormalities upon screening, the potent and natural antioxidant (r)α lipoic acid reduced SCD (relative risk reduction) 43% (p = 0.0076), mean follow-up 6.31 years. Diabetes mellitus patients have high glycemic oxidative stress. Addressing oxidative stress S and P abnormalities can reduce SCD. S and P screening of the general population will be discussed.

Abstract
Introduction Crohn’s disease (CD) is an inflammatory bowel disease, and in ∼ 30% of cases it is associated with perianal manifestations. To identify the extent of the damage and to implement an appropriate treatment, anorectal examination under anesthesia (EUA) is fundamental.
Objective To describe the profile of patients who underwent anorectal EUA in university and private hospitals in the state of Bahia, Brazil.
Methodology A retrospective, descriptive study with 46 patients who underwent anorectal EUA between March, 2016 and November, 2019.
Results A total of 62 anorectal EUAs were performed in 46 patients. With an average age of 36.8 years, the female gender was predominant (52.2%) among these patients. Anal fistulas were the most frequent findings (83.8%), and in most cases they were treated with a seton placement (69.4%). The main recommended surgical indication was a proper evaluation and identification of perianal disease, followed by drainage of the abscess and therefore immunobiological therapy (59.6%).
Conclusion In the present study, the profile of CD patients was similar to those found in the literature, with a high rate of complex anal fistulas. Additional studies are still necessary to further comprehend and treat this particular and debilitating manifestation of the disease.
Magnetic Resonance Imaging of Perianal Fistulas in Clinically Symptomatic Patients and the Correlation Among Plain, Contrast, and Post Jelly MRI Fistulography

Published: July 2021

Abstract
Objectives To evaluate different types of perianal fistulas and their complications on magnetic resonance imaging (MRI) and to compare plain, contrast, and jelly magnetic resonance fistulography findings.
Materials and Methods This prospective study was performed in 30 patients who presented with perianal pus discharge or external fistulous opening. Magnetic resonance imaging of the perianal region before and after giving intravenous contrast and after injecting jelly through a percutaneous opening was performed on a 3T scanner and the results were correlated.
Results The mean age of the patients was 40.13 ± 13.88 years (range 19–75 years). The male to female ratio was 14:1. The most common type of fistula was St. James classification type I, which was seen in 13 patients (43%), followed by type IV in 30%, type III in 16%, type II in 6.66%, and type V in 3.33% of the patients. Using agreement analysis, we compared the number of primary and secondary tracts, internal openings, and horseshoe tracts and found a significant agreement between plain and post Jelly MRI fistulography (kappa statistic close to 1). When comparing plain and contrast MRI, there was significant agreement in the primary and secondary tracts, while statistically insignificant results were obtained (p > 0.05) for the horseshoe tract and internal openings. Contrast injection was helpful in 7 subjects (23.3%) as peripheral enhancement of abscesses were better delineated.
Conclusion Magnetic resonance imaging is the one stop diagnostic modality for perianal fistulas. Acquisition of axial (Ax) T2, axial T2 FS, coronal T2 and coronal T2 FS sequences without administering intravenous contrast or jelly is usually sufficient for the diagnosis of fistulas and their complications.
