Authors: Gil-López Maria Isabel , Sanchez-De la vieja Cristina , Hernández-García Raquel
Published: February 2021

El objetivo del presente estudio fue analizar el perfil funcional de un grupo de jóvenes deportistas, todos pertenecientes al programa nacional de tecnificación de bádminton. Se evaluaron a 43 jugadores de bádminton (26 chicos y 17 chicas), de entre 15 y 16 años, con una experiencia mínima de 3 años de práctica competitiva. Se evaluaron los patrones motores básicos utilizando para ello, la batería de valoración funcional “Basic Functional Assessment” compuesta por cinco pruebas funcionales Overhead Squat test (OHS), Hurdle Step (HS), Forward Step Down (FSD), Shoulder Mobility (SM) y Active Straight Leg Raise (ASLR). Los resultados muestran que el grupo de chicos ha presentado una mayor incidencia de compensaciones totales que el grupo de chicas. La compensación que más se ha repetido en toda la muestra ha sido la protracción cervical, vista en la prueba del SM.  Seguida de la pérdida de flexión de hombros, en el test OHS. No se hallaron diferencias estadísticamente significativas entre géneros. De manera conjunta como equipo de bádminton sin diferenciación de género obtuvieron una media de 20,86 compensaciones sobre 75, mostrando un perfil funcional aceptable. Las compensaciones que más han presentado los jugadores se encontraban en el complejo de la cadera, en el complejo del hombro, así como una falta de estabilidad del core.

Published: February 2021

Las relaciones entre iguales son un factor clave en el desarrollo social de los preadolescentes por ello en el presente trabajo se aborda un estudio sobre las relaciones sociales con especial atención a las relaciones entre ambos géneros. Además, también se estudia la posible repercusión que sobre estas puede tener la implementación de una unidad didáctica (UD) que utiliza como metodología el modelo de Educación Deportiva (ED) en una clase de sexto de Educación Primaria. Para la implementación de esta UD se diseñó un programa compuesto de diez sesiones estructuradas según el modelo de ED y tres actividades complementarias. Del mismo modo, para poder realizar una comparación final de las relaciones entre ambos géneros, se utilizan instrumentos de evaluación en diversos momentos del estudio, antes y después, tales como test sociométricos o entrevistas. Los resultados obtenidos muestran un marcado rechazo inicial entre ambos géneros. Tras la implementación del programa, se refleja una leve mejora en cuanto a la aceptación del género contrario y la disminución de su rechazo, a lo que contribuyen pilares básicos de la ED como son la afiliación o la festividad y siendo los motivos que los alumnos enuncian para aceptar o rechazar al género contrario clasificados dentro de cinco categorías (comportamiento, amistad, compañerismo, dominancia, falta de competencia y otros). Asimismo, se mejoran las relaciones sociales y disminuyen las conductas negativas que se producen en el aula. Para mejorar estos resultados en futuros estudios, es importante que el modelo sea reforzado con el uso de otras técnicas complementarias que favorezcan el trabajo de las relaciones sociales.

Authors: Karabutov N. N.
Published: February 2021

A class of dynamical systems with a single nonlinearity considered. The S-synchronizability concept of input introduced. It is shown that S-synchronizability is a condition for the structural identifiability of a nonlinear system. The decisionmaking on structural identifiability based on the properties analysis for a special class of geometric frameworks. Geometric frameworks reflect properties of the nonlinear dynamic system. Requirements for the model allowed us to obtain a geometric structure based on the input and output data considered. The constant excitation effect of input on the structural identifiability of the system is studied. The constant excitation effect of input studied on the structural identifiability of the system. Nonfulfillment the constant excitation condition gives a nonsignificant geometric framework. Various types of structural identifiability based on structure analysis considered. The concept of d-optimality described properties of the geometric structure introduced. Conditions for non-identifiability of nonlinear system structure obtained if the d-optimality of the geometric framework does not hold for the given properties of the input. Methods for estimating identifiability of the system and determining the identifiability area under uncertainty proposed. The proposed approach is generalized to the system having two nonlinearities. Conditions for partial structural identifiability obtained. Structural identifiability features of this class systems noted. The method for estimating the structure of the system proposed when the condition of structural identifiability satisfied. It has shown how the phase portrait used to estimate the system non-identifiability. A method proposed for constructing the structural identifiability domain of the system. Proposed methods and procedures are applied to study systems with Bouc-Wen hysteresis and two nonlinearity.
Can We Hide in Shadows When the Times are Dark?
Authors: Quandt Thorsten
Published: February 2021

The editorial discusses the relevance of analyzing some problematic aspects of online participation in consideration of events that happened during the preparation of this thematic issue. It critically challenges the eponymous ‘dark participation’ concept and its reception in the field, and calls for a deeper exploration of epistemological questions — questions that may be uneasy and difficult to answer, as they also refer to the issue of balance and scientific positioning in the face of threats to public communication and democratic ideals.
A função dialógico-dialética do narrador em José Saramago / The Dialogical-Dialectic Function of the Narrator in José Saramago
Authors: Garlet Deivis Jhones
Published: February 2021

Resumo: A obra romanesca de José Saramago é reconhecida pelo seu conteúdo de crítica social, sobretudo, ao império do capital e seus efeitos nefastos na vida dos homens e à hipocrisia das elites políticas e econômicas. Dialeticamente, afirma uma posição de valorização do humanismo e da democracia, geralmente evidenciados nos setores sociais mais desfavorecidos. Este conteúdo axiológico, seguramente, é realizado por uma composição formal singular, na qual as partes contribuem para a efetivação de um todo estruturado. Entre as partes dessa composição, salientamos a relevância do narrador e sua função decisiva para a consecução do conteúdo humanista e democrático nos romances. De fato, o narrador saramaguiano apresenta peculiaridades, como a oralidade, o recurso à ironia, os frequentes comentários, a concessão de voz a uma pluralidade de vozes, que informam de sua função alicerçada no dialogismo e na dialética, de forma que a denominamos função dialógico-dialética. Assim, com base em estudos de Bakhtin e Genette, objetivamos explicitar tal função e sua contribuição para a axiologia do universo romanesco do autor lusitano.Palavras-chave: José Saramago; narrador; função dialógico-dialética.Abstract: José Saramago’s romanesque work is recognized for its content of social criticism, especially the empire of capital and its harmful effects on the lives of men and the hypocrisy of political and economic elites. Dialectically, it affirms a position of appreciation of humanism and democracy, generally evidenced in the most disadvantaged social sectors. This axiological content, surely, is realized by a singular formal composition, in which the parts contribute to the realization of a structured whole. Among the parts of this composition, we emphasize the relevance of the narrator and his decisive role in achieving the humanist and democratic content in the novels. In fact, the Saramaguian narrator has peculiarities, such as orality, the use of irony, frequent comments, the granting of a voice to a plurality of voices, which inform of its function based on dialogism and dialectic, in a way that we call it function dialectic-dialectic. Thus, based on the studies of Bakhtin and Genette, we aim to make explicit this function and its contribution to the axiology of the Romance universe of the Lusitanian author.Keywords: José Saramago; narrator; dialogical-dialectic function.

Combination of collagen scaffold with doxycycline for the treatment of cartilage and subchondral bone defects
Authors: Liang Haixiang , Stein Spencer , Swami Pooja , Fanjaniaina Henintsoa , Grande Daniel
Published: February 2021

The repair of cartilage and bone tissue post arthritis or injury in the knee joint is a challenge to the orthopedics. Both doxycycline and collagen scaffolds had been shown with positive influences on the repair of the tissue. Doxycycline inhibits catabolism related enzymes. Collagens provide tissue repair materials. In this study, the influence of doxycycline and jellyfish collagen (JFC) scaffold to the cells in vitro and tissue repair in vivo was studied. Doxycycline was found with a broad inhibition of the matrix metallopeptidases. It also had an enhancement to the progenitor chondrocytes but suppressed the maturation of chondrocytes. JFC (major type II collagen) was seen had improved both type I and type II collagen production during chondrogenesis of mesenchymal stem cells in vitro. Both doxycycline and JFC enhanced the bone formation and had synergistic effects in a late-stage during the bone repair process. However, the cartilage repair was found with no significant influence after the implantations. Overall, the control of metabolism by doxycycline and providing stimulation to collagen production by the implantation of JFC only contribute to bone growth but had little influence on cartilage repair. This indicates the growth of cartilage tissue needs more delicate regulation. The subchondral bone repair, even with some chondrocytes and proteoglycan deposition in the extracellular matrix could not convert to a repair with mature hyaluronic cartilage tissue.

Published: February 2021

Background: The use of fixation screws with uncemented cups is controversial particularly for dual mobility (DM) cups where perforation of the articular surface could compromise implant longevity. We aimed to compare outcomes of total hip arthroplasty (THA) using uncemented DM cups with supplementary screw fixation versus simple press-fit fixation. Methods: From 235 consecutive THAs performed using uncemented DM cups, 203 were fixed by simple press-fit and 32 fixed with additional screws. The Oxford hip score (OHS) and EuroQol 5 Dimensions (EQ-5D) score were available at 3.3±1.1 years. To enable direct comparison, each screw fixation cup was matched to three simple press-fit cups using propensity scores, based on age, sex and bone quality. Results: The two groups had equivalent age, body mass index, gender distribution, femoral morphology and bone quality. Compared to the press-fit group (n=96), the screw fixation group had more surgical antecedents (p=0.032), higher femoral neck angles (p=0.028), and received slightly larger cups (p=0.036). Revision was required for two (6%) screw fixation cups (only one implant-related) and one (1%) press-fit cup (none implant-related). There were no differences between OHS (19±8 vs 18±7, p=0.682) nor EQ-5D (0.63±0.37, p=0.257). Conclusions: Revision rates were greater for DM cups fixed with additional screws than for those fixed by simple press-fit, but clinical scores were equivalent. There was only one implant-related revision (acetabular fracture) in the screw fixation group and it is unclear whether this is related to the additional screws or to patient/surgical factors. Level of evidence: Level IV, retrospective case series.
Quantitative measurement of APC-Resistant factor V clotting activity (FV-Leiden) and potential graduation of the associated thrombo-embolic risk
Authors: MARIE PEYRAFITTE , MARIE VISSAC , JEAN AMIRAL
Published: February 2021

Coagulation Factor V (FV) is a key factor for regulating blood coagulation cascade, and it acts at the crossroads of the intrinsic and extrinsic pathways. It shows a dual activity as the procoagulant cofactor for Factor Xa in the prothrombinase complex, but it also supports an anticoagulant activity in combination with TFPI and Protein S. Its rapid cleavage by Activated Protein C (APC) complexed with Free Protein S (FPS), in presence of phospholipids and calcium, inhibits its activity and limits the propagation of blood coagulation, keeping it to where it is beneficial. Rapid inactivation of active FV by APC-FPS is essential for preventing the risk of thrombosis development. In 1993, Dahlbäck and coworkers reported an inherited disorder characterized by activated protein C resistance (APC-R) and associated to an increased occurrence of thromboembolic events in affected families. In 1994 Bertina demonstrated that this diathesis resulted from a Factor V mutation (R506Q), rendering this factor resistant to inactivation by APC. This mutated Factor V was called Factor V Leiden (FV-L). APTT based assays and molecular biology methods for detecting the mutation were developed, but these methods are only qualitative and classify tested individuals as normals, heterozygous or homozygous for the coagulation defect. Our group developed a quantitative assay for FV-L, which is described in this report, along with its performances. This assay allows to quantitate specifically FV-L coagulant activity, and to graduate its amount in heterozygous or homozygous patients. FV-L is absent in normal individuals and present in homozygous or heterozygous patients, accounting respectively for 100 % or 50 % of blood FV. Its amount is compared with FV clotting activity or antigenic concentration. Measured FV-L activities overlap between heterozygous patients with high FV and homozygous ones with low FV levels. This assay allows to better discriminate for the FV-L associated thrombotic risk, which depends on the effective FV-L concentration rather than on patients’ genetic status. This expectation is supported by literature review, which shows that FV-L concentrations correlate with presence of platelet released microparticles in patients carrying that mutation.
Advances in the laboratory diagnosis of tuberculosis
Authors: Elorraiga Guadalupe , Pineda Guillermo
Published: February 2021

Despite the advances made in the past 30 years in the laboratory diagnosis of tuberculosis (TB), only a small portion of the overall world population has benefitted. The World Health Organization (WHO) has recommended the use of nucleic acid amplification tests (NAAT) to detect TB instead of smear microscopy, since they can detect TB with greater precision, particularly in patients with paucibacillary disease and in individuals living with HIV. A broad range of molecular TB detection tests are currently being developed and evaluated, some for use in reference laboratories and others for peripheral medical care settings and point-of-care. There has been a surge of molecular tests designed, manufactured, and implemented in countries with a high TB load, and some are specifically meant for use in locations that are close to the patient. In terms of drug susceptibility testing, NAAT and next-generation sequencing may provide faster results than traditional phenotype culture. Further, the results of tests that detect or quantify cytokines released in the inflammatory process in latent tuberculosis infection (LTBI), such as the Interferon-Gamma Release Assay (IGRA), or that quantify IL-6 or other cytokines, depend, as in the tuberculin skin tests (TST), on the prevalence of TB in the tested population. We herein review the recent advances in TB detection tests and resistance to anti-TB drugs.

Published: February 2021

Existen observaciones que indican que el campo magnético en la atmósfera solar tiene twist, esto cumple un papel muy importante en diferentes fenómenos solares como la reconexión magnética, las fulguraciones solares, entre otros. Sin embargo, su influencia en este tipo de fenómenos aún no es clara. Con esa motivación, en este artículo se estudia, mediante varias simulaciones numéricas 3D, el efecto del twist del campo magnético en la propagación de ondas torsionales de Alfvén y magnetoacústicas a lo largo de la fotosfera y la cromosfera baja de un Sol con poca actividad. Con la finalidad de simular la dinámica de estas ondas magnetohidrodinámicas (MHD), se solucionaron numéricamente las ecuaciones linealizadas de la MHD ideal en tres dimensiones, asumiendo un Sol con poca actividad, el cual fue alterado con una perturbación inicial tipo twist en el campo de velocidades, para seis valores diferentes del parámetro de twist y tres magnitudes del campo magnético en equilibrio. Particularmente, se analizó la morfología 3D de las líneas de los campos de velocidad y magnético, y el perfil espacial de la componente transversal de estos campos, asociada con las ondas torsionales de Alfvén. Los resultados de las simulaciones numéricas, revelan la amplificación del campo magnético debido al parámetro de twist. Específicamente, se observó que esta cantidad aumenta cuando el parámetro de twist aumenta y es menor para grandes magnitudes del campo magnético en equilibrio. Además, se mostró que el valor máximo de la amplificación en función del twist exhibe un comportamiento exponencial. Finalmente, se observó que el vector de flujo de Poynting es mayor si el twist es mayor y se reduce para campos magnéticos iniciales más intensos.

La frontera sur de Colombia incluye extensos bosques amazónicos con diferentes grupos taxonómicos aún inexplorados. Presentamos una lista de especies de aves registradas entre los ríos Caquetá y Putumayo, o Japurá e Içá, a partir de la recopilación de datos históricos provenientes de especímenes biológicos y muestreos en campo realizados principalmente entre 2015 y 2020. Comparamos la diversidad taxonómica y funcional, así como el interés para el aviturista, en relación con un índice de huella humana que permite clasificar el grado de intervención antrópica. La lista incluye 531 especies distribuidas en 66 familias y 25 órdenes, siendo la familia Tyrannidae la de mayor riqueza. La diversidad taxonómica y el interés para el aviturista disminuyeron con el aumento del índice de huella humana, en tanto que la diversidad funcional no varió tan evidentemente con el grado de intervención humana. El refuerzo de estrategias de monitoreo participativo en las zonas rurales de Colombia puede contribuir al crecimiento económico local y tener alcances regionales de conservación que involucren áreas protegidas y otras zonas de importancia ecosistémica a la espera del establecimiento de programas de conservación participativos.

Published: February 2021

The Life Cycle Assessment is a methodology that studies the environmental aspects and the potential impacts associated with a product or service through the formulation of an inventory of resources. Among the various indicators that measure environmental impacts, the carbon footprint stands out for analyzing the greenhouse gas emissions derived from an activity, process or product. The objective of this work is to compare the carbon footprint of a conventional photovoltaic system and a semitransparentone, designed to meet an energy demand of 386 kWh/day. A higher carbon footprint was obtained for the conventional panel system, totaling 3623 kg CO2-eq/year, while the semitransparent system emitted 2726 kg CO2–eq/year. In both cases, photovoltaic cells and aluminum structures accounted for the greatest contribution to the carbon footprint, in addition to the significant contribution of solar glass. The emission factor was also calculated, associating the electric production capacity with the carbon footprint, obtaining 0.0257 kg CO2-eq/kWh for the conventional system and 0.0193 kg CO2-eq/kWh for the semitransparent system. From the carbon footprint viewpoint, the semitransparent system is the best option, with significantly lower emissions.

Published: February 2021

The aim of this study was to evaluate the methionine plus cystine levels in the diets of laying hens during the rearing period (13-18 weeks old). The diets included a control diet formulated according to NRC and five other diets with different levels of this digestible methionine plus cystine (0.317, 0.356, 0.396, 0.436 and 0.475%) that have been based on the recommendations of the Brazilian poultry and swine tables. Performance, serological and histological variables were evaluated. There was linear effect on final body weight, weight gain, methionine plus cystine intake and feed conversion, and quadratic effect on the serum albumin levels, serum protein levels and relative spleen weight. The estimated level of digestible methionine plus cystine were 0.361%, 0.346% and 0.398%, for albumin activity, serum protein and relative weight of spleen, respectively. The different formulation bases significantly influenced the histology of the liver, small intestine and magnum. It is recommended the use of levels above 0.475% of digestible methionine plus cystine for light laying hens with 13-18 weeks old, which corresponded to a ratio of digestible methionine plus cystine: digestible lysine of more than 98%.

Statistical data show that housing finance has been in wide demand as an option for the purchase of real estate and that the level of default and the number of properties auctioned have also increased significantly in recent years.. These data show that the decision to purchase the financed home is not always carried out in an organized way, impacting on high costs and the difficulty in meeting financial commitments made by the borrower. In this context, the objective of this research is to develop a simulation tool, using Monte Carlo simulation techniques, to help consumers make decisions regarding long-term financing in the acquisition of properties. A large number of simulations, using a real-case study, were carried out to verify the validity of the proposed model, allowing the evaluation the behavior of debt costs. The results obtained in this research indicate that the cost of debt can be reduced by more than 40% if the requester chooses to postpone the financing for a few years in order to obtain a greater financial amount to be given as input, reducing the outstanding balance and the financing period.
Investigation of Microgrid Hierarchical Control and Structure
Authors: Faghihi Tayebeh , Sabzi Shahab
Published: February 2021

This paper offers a literature review on different structures and control strategies of the microgrid. The implementation of a microgrid system provides significant advantages for both electric utility and end-users. Microgrid control is one of the most sophisticated parts of such implementations that must be taken into account before moving to the next steps. The different control objectives and structures of the main grid and microgrid lead to various control methods proposed for microgrids. The hierarchical structure is the most accepted method for microgrid control that has three levels including primary, secondary, and tertiary. The focus of this study will be on the main modes of typical microgrids, types of microgrid and how to control them. The investigation of this paper will give an overview to the readers, and in our next paper, we will focus more deeply on the subject, with a specific concentration on the concept of secondary control and corresponding trending methods.

Generator protection system is one of the complicated industrial systems incorporating many group elements; measurement transformer, relays, circuit breakers and wiring connectors. Generally, protection systems are described using four characteristics; dependability, Sensitivity, rapidity and selectivity. The stator earth fault is a relatively common type of fault. The generators normally have grounded high impedance, that is to say, a ground via a neutral point resistor. This resistance is normally dimensioned to give a ground fault current of the order of 5 to 15 A in the event of permanent earth fault in high voltage terminals of the alternator. Relatively low ground fault currents cause. The new protection technique, it is called an intermittent defect, this type of defect usually has the following characteristics, A very short earth current pulse of high intensity (up to several hundred amps), lasting less than 1 ms. It occurs / disappears automatically over half a period, possibly over several periods, depending on the state of the power grid and the characteristics of the fault. Over longer periods (from several seconds to several minutes), it can evolve into a permanent fault.

One of the key challenges for the training of healthcare professionals (HCPs) is to maintain a good understanding and knowledge of new assistive technologies (ATs) that are currently on the market [1]. Indeed, at present, available training on ATs is limited and does not meet the practice-related needs of HCPs. It is in this context that the ADAPT European project aims to develop a new AT training programme for healthcare professionals, which will also introduce them to the project’s new AT developments - a smart powered wheelchair and a virtual reality wheelchair-driving simulator. The program consists of six multimodal units; five delivered via e-learning and one through a blended method of e-learning and face-to-face sessions. The development of the content is guided by findings from an earlier literature review and an online survey of AT training needs for HCP’s, both undertaken by the ADAPT cross-national research team, comprised of UK and French experts. The level of technical difficulty increases with successive units in order to train all HCPs to use innovative ATs more widely in their practice. A Learning Management System enables the dissemination of the e-learning AT program. Preliminary results from participant unit-specific evaluations available at this stage are overall positive and encouraging.
Angst als Textspur und Bildspur in Graphic Novels zum historischen Geschehen des 20. Jahrhunderts
Authors: Schultze Brigitte
Published: February 2021

Neben vielen anderen Charakterisierungen, etwa ‚Jahrhundert der Diktatoren‘, ist für das 20. Jahrhundert wahrscheinlich auch die Formulierung ‚Jahrhundert der Angst‘ gerechtfertigt. Dieser Beitrag ist ein erster Versuch, die Darstellung von Angst in verbal-piktoralen Narrativen zu erschließen. Text- und Bildspuren zu Angst – politisch genutzte Techniken der Angsterzeugung einerseits und bis zu dauerhafter Traumatisierung gehende Angsterfahrung andererseits – sind in vielen Graphic Novels zur Geschichte des 20. Jahrhunderts ein wesentliches Deutungsangebot. Obwohl ästhetisch und intellektuell anspruchsvoll, somit ein Angebot zur Aufarbeitung von Geschichte, ist diese Fokussierung von Angst der Forschung bislang entgangen. Diese Untersuchung betrifft erlebte und erlittene Geschichte vom Ersten Weltkrieg bis zur Wendezeit um 1989. In einer Auswahl von fünf Graphic Novels deutscher, französischer, polnischer und tschechischer Experten des Genres, bieten gerade die Bildspuren atmosphäri­sche Dichte, Genauigkeit und zugleich Offenheit für weitere Interpretation.
Die drei Bäume von ANNA SEGHERS (Variationen über Furcht)
Authors: Mehnert Elke
Published: February 2021

Als ANNA SEGHERS 1940 mit ihrer Familie versuchte, aus dem von der deutschen Wehrmacht besetzten Teil Frankreichs zu fliehen, schrieb sie Die drei Bäume, drei kurze Texte, die sich mit Angstgefühlen auseinandersetzen – es sind die Angst vor Verfolgung, vor Führungslosigkeit und vor Entfremdung. In der SEGHERS-Forschung haben diese kurzen Geschichten kaum Beachtung gefunden – sehr zu Unrecht, wie die Verfasserin anhand ihrer jahrzehntelangen Erfahrungen im Umgang mit den kurzen Geschichten darstellt.
„Teppiche sind aus Geschichten gewoben“. Problematisierungen generationalen Erzählens in NINO HARATISCHWILIS Das achte Leben (Für Brilka) und JETTE STECKELS Inszenierung am Thalia Theater Hamburg
Authors: Lempp Felix
Published: February 2021

In NINO HARATISCHWILIS Roman Das achte Leben (Für Brilka) versucht die Erzählerin Niza vergeblich, die sowjetische Geschichte Georgiens und die individuelle Geschichte ihrer Familie zwischen 1900 und 2006 aufeinander bezogen darzustellen. Der Aufsatz argumentiert, dass in den Defiziten des Erzählprogramms Nizas Widersprüche einer für den Generationenroman typischen Erzählpoetik produktiv gemacht werden, der es nicht gelingt, individuelle, familiäre und politische Geschichte zu einem sinnstiftenden Narrativ zu verbinden. Am Ende des Romans steht deshalb ein Medienwechsel von der literarischen Geschichtsdarstellung zu ihrer performativen Verkörperung im Tanz, in dem die theatrale Adaption des Romans, wie sie JETTE STECKEL 2017 am Thalia Theater Hamburg inszenierte, bereits angelegt ist.

THE INFLUENCE OF SILICA CALCINATION TEMPERATURE VARIATION TO THE HYDROPHOBICITY AND TRANSMITTANCE ON GLASS SUBSTRATE
Authors: Rohmah Roihatur , Zainuri Mochamad
Published: February 2021

The hydrophobic surface can be self-cleaning. The hierarchy of surface roughness affects the hydrophobic surface. In this research, the hydrophobic surface was fabricated by modification of surface roughness from the composite filler. Natural silica was used as a filler and was done a variation of calcination temperature to modify the hierarchy of roughness formed. The variation of calcination temperature was 800°C, 1000°C, 1200°C, and 1400°C. The coating method was a dip-coating method by 30-second long immersion. A glass as coating media was coated by PVDF/SiO2 composite. The hydrophobic surface could be known from the value of the water contact angle (WCA) formed. If a water contact angle more than 90°, the surface could be called the hydrophobic surface. In this research, the hydrophobicity aspect cause of variation of calcination temperature was known from the value of water contact angle formed on the surface of PVDF/SiO2 composite coating 800°C, 1000°C, 1200°C, and 1400°C was 117,12° ± 0,98°, 107,80° ± 0,91°, 121,31° ± 1,45°, and 111,75° ± 1,47°, respectively.

In this research, Moringa oleifera seeds extract has been shown the ability as a coagulation agent. The molecules that act as the coagulation agents were the proteins which were obtained by the extraction process of the Moringa seeds using NaCl solution. The aim of this research was to characterize and test the effectiveness of the Moringa seeds extract as a phosphate coagulant. The determination of the coagulation process was carried out using a Jar Test method of phosphate solution samples, and then effectiveness the samples were analyzed using a UV-Vis spectroscopy after-treatment of the coagulant dose variations, depositional time, and the pH variations of the samples. The characterization of the extract functional groups was determined using an FTIR spectroscopy. The results of the coagulation phosphate sample examinations showed that the optimum dose of the coagulant was 80 mL/L, with a decrease in the initial phosphate concentration of 17 ppm to 13.58 ppm. The reduction effect of precipitation time and pH also was obtained in this research. The optimum precipitation time and pH were in 30 minutes and pH 8, which reduced the phosphate concentration to 11.697 and 9.6 ppm, respectively. The FTIR spectra of Moringa oleifera seeds extracts before and after interacting with phosphate showed their differences. The interactions between the extract and phosphate were demonstrated by the appearance of buckling vibrations at wavenumbers 1064.2 cm-1, 799.8 cm-1, and 668.8 cm-1. The results of this study indicated that the Moringa seeds extraction with NaCl has potential as a phosphate coagulation agent.

Developing a good pro-pluralism religious education curriculum requires much planning and a deep understanding of the context. In a country like Iraq, where the education system is in decline due to years of conflict, weak governance and management, and a displacement crisis, this becomes a challenging task. This Learning Briefing, prepared during the implementation phase of the Coalition for Religious Equality and Inclusive Development (CREID) project to introduce reform to the religious education curriculum in Iraq, highlights the key areas of best practices and lessons learned from our stakeholder engagement. The aim is to share these learnings with programme managers, donors and partners to help inform future interventions and curricula development on effective approaches and models for improved quality education.
Community Resilience: Key Concepts and their Applications to Epidemic Shocks
Authors: Schmidt-Sane Megan , Hrynick Tabitha , Niederberger Eva
Published: February 2021

The COVID-19 pandemic has exposed long-standing social inequalities and vulnerabilities, with the most disadvantaged and marginalised groups bearing the greatest health, social, and economic burdens. Beyond documenting these vulnerabilities, there is a need to mitigate them and support the resilience of marginalised communities. ‘Community resilience’ can bolster community capacity to cope with the pressures of various shocks; this brief explores how its concepts can be applied to epidemics. It reviews the grey and academic literature on different approaches to community resilience. It covers 1) terminology, 2) lessons from practice, 3) the context of community resilience, 4) a systems approach, and 5) key human and social capacities. Social justice, inequality, equity, and fairness are highlighted as themes in need of further development for resilience as it relates to epidemic preparedness and response. This brief was developed for SSHAP by IDS (led by Megan Schmidt-Sane with Tabitha Hrynick) with Anthrologica (Eva Niederberger).
General characteristics of a bailiff’s legal status in the Russian Empire and the Russian Federation (comparative legal aspect)
Authors: Goltsman Elena
Published: February 2021

Based on the methodology of chrono-discrete monogeographic comparative law, we identify the comparative potential of bailiffs’ legal status in the Russian Empire and the Russian Federation. Until recently, the legislation of the Russian Federation did not give a clear idea of bailiffs’ legal position in the civil service. We believe that, speaking about a bailiff’s legal status and comparing the regulatory framework that regulates it, it is necessary to determine what elements constitute a bailiff’s legal status; to compare comparable, conditionally comparable and incomparable elements of this status. At present, this issue is more definite and developed in comparison with the pre-revolutionary period. Comparison of specific elements of legal status in different historical periods may lead to the development of prac-tical recommendations for improving the current legislation governing the structure and activities of the institution of bailiffs. We designate six ele-ments of bailiffs’ legal status, which are fundamentally comparable in rela-tion to the Russian Empire and the Russian Federation. We also note the need to take into account the specific historical situation in the studied periods, the specifics of the political, economic, and social structure, and the peculiarities of legal awareness and mentality.
Theoretical and practical aspects of a legal experiment (on the example of a new procedure experiment for pre-trial appeal against decisions of a control (supervisory) body)
Authors: Lipuntsova Anna
Published: February 2021

We raise questions related to the theoretical and practical aspects of the implementation of a legal experiment in the Russian Federation. The purpose of the study is to consider the problem of conducting an experiment on pre-trial appeal against decisions of the control (supervisory) body, ac-tions (inaction) of its officials, which is implemented from August 17, 2020 to June 30, 2021. The study of this topic is particularly relevant in the light of the state control and supervision reform through the introduction of the “regulatory guillotine” mechanism. We analyze the approaches to the essence of the legal experiment that have developed in science, consider the experiments previously conducted in the country, characterize the position that determines the procedure for conducting a legal experiment in the field of pre-trial appeal against decisions of control (supervisory) bodies, present the positions of practicing lawyers on the implementation of this experiment. We conclude that the implementation of a legal experiment in practice is positive, since it contributes to the development of legal regulation in one area or another and the use of this institution in the field of control and supervisory relations will allow the continued effective reform of the state control and supervision system.
The value, concept and essence of appeal proceedings in civil cases
Authors: Usich Liliya
Published: February 2021

This work is devoted to identifying the significance of the appeal proceedings in civil cases. We emphasize that the right to judicial protection is one of the fundamental human rights. To achieve this goal, we set the following tasks: define the concept of appeal proceedings; characterize the essence of the appeal proceedings in civil cases. In the course of studying the issue, we use the methods of scientific knowledge, based on the results of which the appropriate conclusions are drawn: despite the wide recognition of the appeal proceedings in the Russian Federation, we note the need to improve the efficiency of this institution due to certain omissions in the legislation. As a result, we define what should be understood as an appeal – consideration of cases that have not entered into legal force. By virtue of this, the importance and significance of the appeal proceedings as an appeal tool, as well as the direct correction of judicial errors, is noted both by the norms of domestic legislation and by international human rights bodies. The indicated gaps in the legislation show the absence of clearly defined boundaries, which creates problems in determining the value and essence of the appeal proceedings both at the theoretical and practical levels. In particular, there is a controversy on the appeal proceedings’ importance. However, the doctrine identifies two main elements, the essence of the appeal proceedings is: 1) the repetition of the case; 2) verification of the judicial act. Nevertheless, despite the high prevalence of appeals in civil proceedings, the issue of improving the effectiveness of this institution is still relevant, which leads to the inefficiency of civil proceedings in general.
