An Extragenital Colonic Salpingiosis
Authors: D'Ovidio Valeria , Maggi Daniela , Bruno Giovanni , Fratoni Stefano , Guazzaroni Marco 
Published: August 2021

Endosalpingiosis is a rare condition characterized by the presence of benign fallopian tubal-like glandular epithelium derived from Mullerian ducts, usually affecting the serosal surfaces of the pelvis and peritoneum. It is histologically differentiated from endometriosis as endosalpingiosis lacks endometrial stroma. Endosalpingiosis tends to affect older women and has been associated with ovarian serous tumors of low malignant potential.
The extragenital endosalpingosis is typically without symptoms, reported only once as chronic pelvic pain. It rarely affects the appendix but can be mistaken for acute appendicitis or appendiceal tumors.
No reports of endoscopic findings have been never described. Its treatment is challenging and provides a multidisciplinary approach with gynecologist, surgeon and gastrointestinal endoscopist. Our case reports for the first time an endoscopic finding of colonic salpingiosis and it is challenging both for the diagnosis and for the treatment.
Enhancing and Restricting Factors of Formal Voluntary Engagement in Tyrol and the Impact of the Pandemic
Authors: Ganner Julia , Kerschbaumer Lukas , Tanzer Christina 
Published: August 2021

Purpose: The insurmountable tensions and turmoil caused by the COVID-19 pandemic in welfare systems worldwide demand governmental as well as non-governmental support, especially from the volunteer sector, which can be a powerful resource for mitigating the pandemic’s impacts. To identify ways of mobilising the enormous human resources of the baby boomer generation in particular, whose members are currently on the brink of entering retirement, the factors that have enabled and restricted volunteer management during the pandemic in Tyrol, Austria are examined.
Design/Method/Approach: Following a qualitative approach, the authors performed 27 problem-centred interviews with representative senior citizens, retirees and individuals about to retire and companies in Tyrol. The authors evaluated the data in qualitative content analysis.
Findings: Self-determination, time flexibility, acceptance of volunteer work in one’s social network and previous personal experience with volunteering are key determinants of sustainable volunteer work amongst retirees. Companies and a well-established acquisition management strategy also play a significant role in promoting volunteer work.
Practical Implications and Originality/Value: The study involves a holistic analysis of volunteer work at the individual and organisational levels. By capturing the potential of e-volunteering and how it improves the capacities of classic face-to-face volunteer work, it can support the development of more resilient infrastructures for supporting volunteer work.
Research Limitations/Future Research: The interpretation of visual and non-verbal signals was difficult due to the use of phone and online interviews, and the results should not be generalised. Even so, our findings pave the way for future studies on mechanisms determining virtual volunteering and volunteer management.

Моделювання первинної продукції компонентів надземної частини дерев сосни звичайної Східного Полісся України
Authors: Matushevych Liubov , Lakyda Petro 
Published: August 2021

Первинну продукцію компонентів надземної фітомаси (стовбура і крони) оцінено для дерев сосни звичайної, які ростуть переважно у чистих та мішаних (домішка від 1 до 3 од.) соснових насадженнях штучного походження Східного Полісся України. Насадження високопродуктивні (II, I, Ia і вище класів бонітету), середньо- та високоповнотні, ростуть у свіжих борах (А2), суборах (B2) та сугрудах (C2). Використано дані 80 тимчасових пробних площ (ТПП), які закладено у соснових деревостанах Сумської (36 ТПП) та Чернігівської (44 ТПП) областей. Зрубано й обміряно 900 модельних дерев (МД) сосни звичайної, з яких 226 МД опрацьовано з пофракційним оцінюванням компонентів надземної фітомаси та 674 МД – без оцінювання фітомаси крони. Обмір моделей і розрахунки первинної продукції компонентів надземної фітомаси дерев сосни звичайної виконано за допомогою удосконалених загальноприйнятих методів та розробленого алгоритму.
Сукупність значень дослідного матеріалу характеризується їх нормальним розподілом за віком, діаметром, висотою дерев та відносною повнотою насаджень. Встановлено тісноту зв’язку між досліджуваними показниками модельних дерев сосни звичайної (від помірного – -0,31 < r < -0,50, до дуже високого – r > 0,91); слабкої тісноти зв'язок (0,11 < r < 0,30) виявлено між повнотою насаджень та часткою поточного об’ємного приросту з показниками компонентів фітомаси крони дерев.
Розраховано регресійні математичні моделі для оцінювання абсолютного та відносного поточного об’ємного приросту деревини стовбурів, об’єму кори стовбурів, маси деревини, кори гілок і маси хвої в абсолютно сухому стані, в яких аргументами є вік та діаметр дерев (R2 = 0,72-0,92). Для частки хвої 1-го року зв’язок з віком дерев обернений та помірний, але значущий на 5%-му рівні (R2 = 0,33).
Розроблені нормативні таблиці первинної стовбурової продукції деревини та первинної продукції надземної частини дерев сосни звичайної показали, що за однакового діаметра зі збільшенням віку дерев первинна продукція стовбурової деревини збільшується лише до певного віку, а досягнувши максимуму – зменшується. Зі збільшенням діаметра за однакового віку первинна продукція стовбурової деревини зростає. Первинна продукція надземної частини дерев, подібно до окремих компонентів надземної фітомаси, зі збільшенням віку та діаметра також збільшується. У типових лісорослинних умовах Східного Полісся середньовікове дерево (50 років) сосни звичайної в надземній частині може нагромаджувати 15,22 кг·рік-1 первинної продукції.

A Ground-Motion Prediction Equation for the Western and the Southwestern Parts of China Based on Local Strong-Motion Records and an Overseas Reference Model for the Vertical Component
Authors: Xing Hao , Zhao John X. 
Published: August 2021

ABSTRACT
A ground-motion prediction equation for the vertical ground motions from the western and the southwestern parts of China (referred to as SWC) is presented in this study. Based on the Xing and Zhao (2021) study, the Zhao et al. (2017) model (referred to as ZHAO2017) for the shallow crustal earthquakes in Japan was used as the reference model. We used a bilinear magnitude-scaling function hinged at a moment magnitude (Mw) of 7.1. The magnitude-scaling rate for events with Mw&gt;7.1 was determined by records from the SWC dataset and the large events in the Pacific Earthquake Engineering Research Center Next Generation Attenuation-West2 dataset. Site classes (SCs) were used as the site response proxy. All other parameters were derived from the SWC dataset only. The magnitude-scaling rates for events with Mw≤7.1 in this study are larger than in the ZHAO2017 model at most periods. The absolute values of the geometric attenuation rates are larger, and the absolute values of the anelastic attenuation rates are smaller than in the ZHAO2017 model. The between-event standard deviations are smaller than in the ZHAO2017 model at short periods, and the within-event standard deviations are larger than in the ZHAO2017 model at all periods. The differences in the between-site standard deviations vary significantly from one SC to another. We also find that the between-event and within-event residuals are almost independent of magnitude and source distance. The response spectrum attenuates less rapidly than in the ZHAO2017 model at distances less than 30 km.
A 3D Optimized Frequency–Wavenumber (FK), Time–Space Optimized Symplectic (TSOS) Hybrid Method for Teleseismic Wave Modeling
Authors: Meng Weijuan , Yang Dinghui , Dong Xingpeng , Ma Jian 
Published: August 2021

ABSTRACT
Although teleseismic waveform tomography can provide high-resolution images of the deep mantle, it is still unrealistic to numerically simulate the whole domain of seismic wave propagation due to the huge amount of computation. In this article, we develop a new three-dimensional hybrid method to address this issue, which couples the modified frequency–wavenumber (FK) method with the 3D time–space optimized symplectic (TSOS) method. First, the FK method, which is used to calculate the semianalytical incident wavefields in the layered reference model, is modified to compute the wavefields efficiently with a significantly low-memory requirement. Second, 3D TSOS method is developed to model the seismic wave propagating in the local 3D heterogeneous domain. The low memory requirement of the modified FK method and the high accuracy of the TSOS method make it feasible to obtain highly accurate synthetic seismograms efficiently. A crust–upper mantle model for P-, SV-, and SH-wave incidences is calculated to benchmark the accuracy and efficiency of the 3D optimized FK-TSOS method. Numerical experiments for 3D models with heterogeneities, undulated discontinuous interfaces, and realistic model in eastern Tibet, illustrate the capability of hybrid method to accurately capture the scattered waves caused by heterogeneities in 3D medium. The 3D optimized FK-TSOS method developed shows low-memory requirement, high accuracy, and high efficiency, which makes it be a promising forward method to further apply to high-resolution mantle structure images beneath seismic array.

Authors: Medeiros Neta Olívia Morais de , Lucas Marcelly Kathleen Pereira 
Published: August 2021

Este trabalho tem como objetivo analisar as ações do Estado para o desenvolvimento do ensino agrícola no Rio Grande do Norte, bem como a influência das determinações legais nesse processo no período de 1910 a 1967. Para isso, realizou-se mapeamento e análise documental das mensagens dos governadores do Rio Grande do Norte e dos relatórios do Ministério da Agricultura, os quais se constituem como fontes a esta investigação. O recorte temporal justifica-se pelo Plano Geral do Ensino Agronômico de 1910 e a transferência do ensino agrícola para o Ministério da Educação e Cultura. O referencial teórico baseia-se na concepção de educação profissional conforme Manfredi (2003) e na dimensão da história política de acordo com René Rémond (2003) e José D’Assunção Barros (2005). Com a análise, percebeu-se que o ensino agrícola, no período de 1910 a 1967, era definido pelas determinações do Ministério da Agricultura em suas diferentes denominações e organizações ao longo dos anos. E, no Rio Grande do Norte, as principais ações para o desenvolvimento desse ensino foram a implantação da Escola de Agricultura e Criação, o Campo de demonstração de Macaíba, os cursos ambulantes que eram ministrados no Campo, a Escola Agrícola de Jundiaí, o Curso de Especialização para o Serviço do Algodão, as Semanas Ruralistas e cursos e palestras ministrados nas visitas da Inspetoria Agrícola

Published: August 2021

El síndrome cistocerebral fue descrito por primera vez en 1990 por Blackburn y Dunn. Los casos estudiados fueron varones ancianos con síndrome confusional agudo y retención urinaria aguda que, tras un drenaje vesical, presentaron resolución completa del cuadro clínico. Se reporta el caso de un anciano con disminución rápida del nivel de consciencia, mioclonías, hipotensión arterial, bradicardia y retención aguda de orina que experimentó total remisión del cuadro clínico luego del drenaje vesical correspondiente. Se describen, asimismo, los posibles mecanismos implicados en el origen de este síndrome y las alteraciones hemodinámicas y autonómicas subyacentes. Se sugiere considerar al síndrome cistocerebral en el diagnóstico diferencial de pacientes varones ancianos con síndrome confusional o deterioro cognitivo e hipertrofia prostática y que presenten, además, un episodio de retención urinaria aguda.

Abstract
PurposeTo determine the prevalence, clinical stage at presentation and factors associated with pelvic organ prolapse (POP) among women attending the gynecology outpatient clinic at Mbarara Regional Referral Hospital (MRRH), Uganda. MethodsWe conducted a cross sectional study at the gynecology outpatient clinic of MRRH from September 2019 to January 2020. Multiple logistic regression analysis was done to determine factors associated with pelvic organ prolapse. Results Of 338 participants enrolled, the prevalence of POP was 27.5% (n=93). POP stages were: stage I 11.8% (n=11), stage II 63.4% (n=59), stage III 16.1% (n=15) and stage IV 8.9% (n=8). Grand-multiparity (aOR 17.1, 95% CI: 1.1 – 66.6), birth weight more than 3.5kg (aOR 3.7, 95% CI: 1.1 – 12.6), perineal tears (aOR 6.5, 95% CI: 2.1 – 20.2), peasant farmer (aOR 6.9, 95% CI: 1.6 – 29.9) and duration of labour in the first delivery > 24 hours (aOR 5.7, 95% CI: 1.2 – 29) were significantly associated with POP. ConclusionPOP is common among women attending the gynecology clinic at MRRH with most of them presenting with stage II. There should be routine screening for POP to enable early identification and management especially in those who are grand multiparous, peasant farmers and history of perineal tears.
Analytical and Experimental Analyses of Nonlinear Vibrations in a Rotary Inverted Pendulum

Published: August 2021

Abstract
Gaining insight into possible vibratory responses of dynamical systems around their stable equilibria is an essential step, which must be taken before their design and application. The results of such a study can significantly help prevent instability in closed-loop stabilized systems through avoiding the excitation of the system in the neighborhood of its resonance. This paper investigates nonlinear oscillations of a Rotary Inverted Pendulum (RIP) with a full-state feedback controller. Lagrange’s equations are employed to derive an accurate 2-DoF mathematical model, whose parameter values are extracted by both the measurement and 3D modeling of the real system components. Although the governing equations of a 2-DoF nonlinear system are difficult to solve, performing an analytical solution is of great importance, mostly because, compared to the numerical solution, the analytical solution can function as an accurate pattern. Additionally, the analytical solution is generally more appealing to engineers because their computational costs are less than those of the numerical solution. In this study, the perturbative method of multiple scales is used to obtain an analytical solution to the coupled nonlinear motion equations of the closed-loop system. Moreover, the parameters of the controller are determined, using the results of this solution. The findings reveal the existence of hardening- and softening-type resonances at the first and second vibrational modes, respectively. This led to a wide frequency range with moderately large-amplitude vibrations, which must be avoided when adjusting a time-varying set-point for the system. The analytical results of the nonlinear vibration of the RIP are verified by experimental measurements, and a very good agreement is observed between the results of both approaches.

Published: August 2021

Abstract
Spatial interpolation methods usually differ in their underlying mathematical concepts, each with inherent advantages and drawbacks depending on the properties of data. This paper, therefore, aims to compare and evaluate the performances of well-established interpolation techniques for estimating monthly rainfall data in Thailand. The selected methods include the inverse distance-based method, multiple linear regression (MLR), artificial neural networks (ANN), and ordinary kriging (OK). The technique of searching nearest stations is additionally imposed for some aforementioned schemes. The k -fold cross-validation method is exploited to assess the efficiency of each method, then the metric scores, RMSE, and MAE are used for comparisons. The results suggest the ANN might be the least favorite as it underperforms in many folds. While the OK method provides the most accurate prediction, the inverse distance weighting (IDW), particularly inverse exponential weighting (IEW), and MLR are considerably comparative. Overall, IEW is plausible for monthly rainfall estimation of Thailand because it is less computationally expensive than the OK and its flexible computation.

Abstract
Background
The results of a previous study verified that umbilical cord mesenchymal stem cells (UCMSCs) have good therapeutic effects for the treatment of HBV-related acute-on-chronic liver failure (ACLF) and liver cirrhosis (LC). Nevertheless, it is still unknown whether the effects of UCMSCs are affected by recipient age.
Methods
Patients treated with UCMSCs who met the criteria of HBV-related ACLF and liver cirrhosis were identified in this retrospective observational study. Patients were divided into subgroups according to the World Health Organization (WHO) age criteria (< 45 vs. ≥45 years). Group A included young ACLF patients (< 45 y), and group B included older ACLF patients (≥ 45 y). Young LC patients (< 45 y) were assigned to group C, and group D included older LC patients (≥ 45 y). Patients’ clinical characteristics, demographics, biochemical factors, and model for end-stage liver disease (MELD) scores were compared for 24 weeks.
Results
Sixty-four ACLF patients and 59 LC patients were enrolled in this study. Compared with patients in groups B and C, patients in group A did not show significant superiority in terms of the levels of ALT, AST, TBIL, AFP, and PTA and MELD scores. However, the median decrease and cumulative decrease in the TBIL and ALT levels of patients in group C were larger than those of patients in group D after four weeks of UCMSC transfusions. For older patients (≥ 45 y), the cumulative decrease and the median decrease in the TBIL of ACLF patients were significantly greater than those of LC patients after UCMSC treatment. However, the median decrease in ALT levels of ACLF patients was significantly greater than that of LC patients during UCMSC treatment, and the cumulative decrease in ALT levels of ACLF patients was significantly greater than that of LC patients at all time points.
Conclusion
The therapeutic effects of UCMSCs for HBV-related acute-on-chronic liver failure and liver cirrhosis varied partly by patient age. Assessing patient age is necessary prior to UCMSC clinical use.
