Authors: Zubieta Núñez Filomeno
Published: November 2021

La conmemoración de los 200 años de la Independencia nacional y de vida republicana nos invita, entre otras acciones, a dar una mirada a la producción historiográfica sobre el proceso de la independencia nacional, especialmente en las provincias. ¿Qué se hizo y qué se está haciendo en las provincias y en el interior del país por conocer y valorar la participación de sus ancestros en el proceso de la independencia? Un balance sobre las publicaciones históricas relativas a la independencia de los últimos años, en esta coyuntura del bicentenario de la independencia, es lo que se ofrece en este estudio, tomando como referencia el llamado Norte Chico, el espacio geográfico que hoy ocupan las provincias de Barranca, Huaura, Huaral (la antigua provincia de Chancay) del departamento de Lima.
Sociedad y ciudad en tiempos de Felipe II y la construcción del Virreinato del Perú. Notas sobre los indígenas de Catacaos y la destrucción de Payta por Cavendish (1587)
Authors: Espinoza Claudio César
Published: November 2021

En esta ocasión buscamos presentar la estructura colonial que construyen los virreyes en Piura y examinar la situación social que vive el pueblo y la comunidad indígena de Catacaos en el último tercio del siglo XVI. La descripción y análisis del ataque y la destrucción de la ciudad y puerto de Payta en 1587 nos sirve como un acontecimiento político que permitirá observar el funcionamiento no solo del sistema virreinal sino también de los patrones y sistemas que adoptaron los indígenas de Catacaos para ajustarse a un sistema político en proceso de construcción. En suma, nos introducimos a conocer el papel de las estructuras coloniales que introduce Felipe II en el corregimiento de Piura y el proceso social que vive Catacaos y otros pueblos indígenas para asegurar el comercio marítimo y terrestre de la plata de Potosí en el norte del Perú y el fortalecimiento de la ciudad de San Miguel de Piura del Villar en 1588.

El objetivo del presente estudio fue evaluar la tasa de producción de embriones in vitro hasta el estadio de blastocisto con dos medios de fertilización: FERT-TALP y TCM-199 modificado, cultivado en el medio BOEC, a partir de ovocitos recolectados por aspiración folicular de ovarios de vacas criollas obtenidos del matadero. Se recolectaron 281 ovocitos, 179 para el medio FERT-TALP y 144 para TCM-199 modificado. Los ovocitos fueron sometidos al proceso de maduración, fecundación y cultivo embrionario in vitro. Se obtuvo una tasa de clivaje de ovocitos de 25.8% en FERT-TALP y 2.4% en TCM-199 modificado a las 18 horas pos-fertilización. Asimismo, a las 48h se obtuvo 87.7% de clivaje total en FER-TALP y 40.5% en TCM-199 modificado, cuyo porcentaje de embriones con 4 a 8 células fue de 64.5 y 26.2% respectivamente. En la fase de mórula y blastocisto se alcanzó una tasa de 10.3 y 3.9% en FERT-TALP, respectivamente, mientras que ninguno se logró con el medio TCM-199 modificado.

El objetivo del estudio fue determinar el efecto de la tasa de fotogramas sobre diferentes profundidades de cámara de recuento espermático en semen de verraco y analizar la distribución de los espermatozoides en los campos longitudinales de la cámara de conteo. Se colectó una muestra de semen a 10 verracos Pietrain de 2-3 años. Se determinaron ocho parámetros de cinética espermática mediante el sistema CASA (Computer-assisted semen analysis)-Mot (ISAS®v1). Se utilizaron cámaras ISAS®D4C con profundidades de 10, 16 y 20 μm a una frecuencia de captura de imagen de 25, 40 y 60 fotogramas por segundo (fps). La profundidad de cámara afectó las variables de cinética espermática, obteniéndose valores más altos a 20 µm. La tasa de fotogramas (FR) presentó una relación positiva con los parámetros de cinética obteniéndose valores más altos a 60 fps, excepto para la amplitud del desplazamiento lateral de la cabeza (ALH) que presentó un comportamiento inverso. La variable más sensible al cambio en FR fue la velocidad curvilínea (VCL), donde el mejor nivel se observó con 80 fps. Se observó una disminución progresiva en los patrones cinemáticos conforme los espermatozoides avanzaban por los campos de las cámaras. Se concluye que el uso de diferentes cámaras de recuento y el incremento en el número total de fps genera cambios significativos en la estimación de parámetros de cinética espermática en el verraco.

Omniscience and ignorance
Authors: Pritchard Duncan
Published: November 2021

God’s omniscience generates certain puzzles, not least regarding how such omniscience is compatible with human free will. One option in this regard is to impose limitations on the scope of God’s knowledge, but that then poses the further question of how such limitations can be compatible with God’s nature as a perfect being. I offer a novel way of approaching these questions, which appeals to what I claim is an independently motivated distinction between lacking knowledge and being ignorant. In particular, it is contended that God’s omniscience is best understood not as a complete knowledge of all truths, but rather as a kind of deliberate non-knowing (such that the non-knowing does not indicate any cognitive lack on God’s part) that excludes ignorance. God might not know all truths, but that’s not because of any cognitive lack, and there is certainly no truth about which he is ignorant.
Mapping the (Digital) Terrain
Authors: Anderson Bradford A. , Dillon Amanda
Published: November 2021

This essay maps out some of the different ways in which the Bible intersects with digital culture, particularly in its written or textual dimensions. Four broad categories are used to give shape to the discussion: (1) the emergence and development of digital Bibles; (2) the use of digital biblical texts in religious services, liturgy, and other congregational contexts; (3) the intersection of biblical research and digital culture in academic scholarship; and (4) the iconic function of the digital biblical text in social and cultural contexts. What emerges is a picture of a diverse interrelationship between the Bible and digital culture, though not surprisingly, this is more evident in areas where there is a focus on the “text” rather than on material dimensions often associated with the sacred book.
Satguru’s Word, Online and Offline
Authors: Bochkovskaya Anna
Published: November 2021

This essay discusses offline and online representation of the Avtar Bani—a controversial sacred text of the Sant Nirankari Mission (“Universal Brotherhood”) listed by mainstream Sikh authorities as one of the six most “dangerous” religious organizations/sects in present-day India, which is understood to undermine the religious and moral values of Sikhs. Since its publication in 1957, the Avtar Bani has been used by Sant Nirankaris as an alternative to the Guru Granth—the sacred scripture of Sikhism. Mainstream Sikhs consider the Avtar Bani derogatory to the Sikh faith and demand that it be banned by the Punjab government. Nevertheless, copies of the text are kept in Sant Nirankari temples in Punjab and beyond; and yet, unlike the Sikh scripture, they have never been iconized. In the past decade, online representation of the book has become quite popular owing to Sant Nirankari Mission’s efforts to use digital technologies for promoting its ideology, especially among the Punjabi diaspora.
Silent Partner: Design and Making in the Early Modern Architecture of Britain
Authors: Cassey Christine
Published: November 2021

This article argues that, in early modern architecture in Britain, the role of making has been subordinated to that of design. It takes it cue from Gottfried Semper’s image of the architect in antiquity as choragus or orchestrator of the many skills required to create a building, and demonstrates that knowledge of materials and craftsmanship informed the design process. It argues that the architect’s role as orchestrator of craft production has been overlooked due to an overemphasis on conceptual design. The relationship of conceptual and intuitive approaches to building is explored, as is communication between architect and craftsmen through models and large-scale working drawings. The nonarchitectural concerns of plastic artists involved in architectural production are noted. Finally, historiographical tendencies toward stylistic and biographical attribution are shown to militate against a holistic view of design and craft in early modern architecture.

Introduction. Subdural hygromas (SDGs) are the accumulation of fluid in the subdural space. Arachnoid cysts (ACs) on the other hand are common cerebrospinal fluid (CSF) containing lesions of the central nervous system, located within the subarachnoid space. They are generally found incidentally on neuroimaging studies and remain asymptomatic throughout the life. Rupture into the subdural space resulting in subdural hygroma (SDG) is relatively rare. Aim. We aimed to show the importance of the radiological follow up in head trauma patients having large ACs. Description of the case. We report a case of a 69-year-old male patient with a known large Galassi type III AC, presented to our hospital with traumatic brain injuries and re-presented with acute posttraumatic SDG in association with AC rupture. Conclusion. This case emphasizes the importance of radiological follow up in head trauma patients having large ACs to reveal and appropriately manage traumatic subdural collections.

Introduction. Azygos anterior cerebral artery is a rare variant of the anterior segment of the circle of Willis caused by an unusual fusion of the normally paired A2 segments of the anterior cerebral artery (ACA). Despite its rare occurrence, it is associated with various vascular and structural cerebral abnormalities, particularly berry aneurysms. Aim. We aimed to present a case of a 41-year-old female patient who presented to our neurology department with complaints of headache. Description of the case. She had a positive paternal history of aneurysmal subarachnoid hemorrhage. Magnetic resonance angiography (MRA) of her brain revealed an azygos ACA (bifurcating into two pericallosal arteries) which was associated with a saccular aneurysm at its bifurcation point. She was referred to the interventional radiology department for preventive endovascular treatment. Conclusion. Azygos ACA carries a high risk of aneurysm development and its occlusion can potentially compromise blood supply to both cerebral hemispheres. It is therefore crucial for clinicians to be aware of its significance and to report its presence in angiographic studies.

Teachers play an important role in the development of human capital by nurturing and building the intellectual capacity of learners. Academic research revealed that teachers, particularly in Technical Vocational Education and Training (TVET) colleges are faced with array of challenges constricting the drive towards equipping students with the appropriate practical skills as a result of dwindling motivation. Previous studies in the canon of motivation and performance studies have largely focused on industrial organizations and financial institutions with a sparse attention on teachers of TVET colleges of education in Nigeria. The paper seeks to stimulate the important discourse of motivation as a pathway to the realization of effective teachers’ performance in Nigeria’s TVET colleges of education. The Multiple Case research design was employed with a total of 120 teachers recruited from three selected TVET colleges. Findings revealed that intrinsic motivation has no significant association with teachers’ performance. A positive and significant association exists between extrinsic motivation and teachers’ performance. Amongst all other factors of motivation, total basic salary package appears to be the most impactful motivating factor for teachers. The study makes a case that for a proactive and robust teachers’ performance, TVET must appreciate and harness effective extrinsic motivational strategies for viable teachers’ performance.

Belongingness to Canada: Synthesizing Canadianness and Muslimness among Newly Emergent Canadian Muslims
Authors: Haq Muhammad Izzul
Published: November 2021

The recent statistic reveals the number of Canadian Muslims increases multifold in decades. It is predicted that the Canadian Muslim population will grow significantly. The demographic postures of varied Canadian Muslims offer several features requiring scholarly attention and action from all interested stakeholders to look into the situation. That is to evoke Canadianness among those newly emergent Canadian Muslims who came to Canada as immigrants or born here and grown-up as Muslim. When each boundary is negotiated, the spectrum of Muslimness and Canadian-ness is synthesized in the making. This ongoing situation demands particular action to nurture a sense of belongingness for newly emergent Canadian Muslims to protect and promote Canadian multicultural society amidst external and internal challenges such as Islamophobia and radicalism. Based on scoping reviews on selected pieces of literature, the idea of finding a new model or denomination of Islam in Canada is a convincing step to synthesize Canadianness and Muslimness, which reflect the empirical situation of newly emergent Muslims in Canada. The history of the first mosque built in Canada taught us how the synthesis can be practically applied, how flexible Islam can be genuinely promoted, and the lines of doctrine and cultural difference can be deliberately blurred. This ethos demonstrates compatibility with Canadian values of openness and respect for diversity.

THE RESULTS OF TREATMENT OF GIANT CELL TUMOR OF LONG BONES WITH DENOSUMAB
Authors: Diedkov Anatolii , Maksimenko Bogdan
Published: November 2021

Surgical intervention remains a gold standard for the treatment of giant cell tumors (GCT) of long bones. The significant risk of recurrence after the curettage and a high complication rate after radical resections is still an unsolved problem. Targeted therapy with denosumab could solve this problem in favor of curettage, but recent studies have shown negative results with denosumab in such situation. Objective. To analyze the results of the denosumab application in patients with long bone GCP with indications for joint salvage surgery. Methods. We compared the treatment results in two groupsof patients: 1st retrospective (control) group — 57 patients, who underwent curettage with surgical treatment and the 2nd prospective (main) group — 42 patients with combination of surgery with neoadjuvant and adjuvant denosumab tretment. In the 2nd group of patients received 5 neoadjuvant and 5 adjuvant cycles of denosumab. The median follow-up period was 189 months in the control group, and 45 months in the main group. Results. Disease progression which identified as a local recurrence was revealed in the control group in 15 patients (25.4 %) and in 7 patients (16.7 %) in the maingroup (p = 0.19). In the main group, the median time to relapse was 19.8 months (8–34 months) from the date of surgery, in the control group — 15.1 months (9–28 months), respectively. The statistically significant difference in relapse-free survival (RFS) between patients in the main group and in the control group (p = 0.18) was not revealed. But the 5-year RFS in the main group was higher and reached to 85 % (95 % CI 74–96 %) versus 75 % (95 % CI 64–86 %) in control group, respectively. There was no evidence of malignant transformation in the main group and one case in retrospective group. Conclusions. The application of denosumab in the regimen before and after curettage is associated with lees number of relapses — 16.7 % vs. 25.4 % without denosumab, respectively. The lack of statistically significant difference between groups does not provide the sufficient reasons for denosumab prescription in neoadjuvant regimen. But adjuvant administration of denosumab can be considered as preventing factor of recurrence after primary tumor curettage, which may be perspective for further study and optimization of indications for its application in patients with GCT.
THE USE OF TRANEXAMIC ACID IN ARTHOPLASTY OF LARGE JOINTS (LITERATURE REVIEW)
Authors: Filipenko Volodymyr , Pidgaiska Olga , Poplavska Karolina , Hubskyi Stanislav
Published: November 2021

Endoprosthesis of large joints is an efficient method to restore the functional capacity of a limb, to increase the patientʼs motor activity, to eliminate the pain syndrome and to recover self-service. However, there is a risk of certain complications, one of which is massive blood loss. There have been recent publications on the feasibility of the use of tranexamic acid in the arthroplasty of large joints to prevent and reduce blood loss. The objective is to identifythe trends in the use of tranexamic acid in orthopedics and traumatology to prevent blood loss in the arthroplasty of large joints without increasing the risk of other complications. Methods. The search for the scientific information was conducted in Google Scholar, PubMed, World Digital Library, ScienceDirect. Results. The literature review is devoted to the topical issue of the present dayʼs orthopedics, which is the use of tranexamic acid to prevent bloodloss in arthroplasty of large joints. According to the studies, the use of tranexamic acid significantly reduces the overall blood loss without increasing the risk of complications such as thromboembolism. The risk of complications of infectious genesis and of those due to the blood transfusion is also reduced using tranexamic acid. It is determined that the combined intra-articular and intravenous injection of tranexamic acid is more efficient than the applicationof either method separately. However, the comparative results of the ways of administration and the dosage regimen are quite ambiguous. The question of the optimum dose of the medication, which would provide maximum efficiency, without increasing the risk of complications is still to establish. It is advisable to conduct further research on the use of tranexamic acid to determine the efficiency of the ways of injection, dosing regimen taking into accountthe patients' demographic features, their age, concomitant pathology, time of surgery and other factors.

ABSTRACT Objective To understand how Undergraduate Nursing Students signify the university context. Method A qualitative research, of a phenomenological nature, based on the ontology of Maurice Merleau-Ponty, with the participation of 41 undergraduate nursing students from a public university in the interior of Bahia, Brazil. Data were collected from February to April 2019, using four wheels of Community Therapy, whose produced material was submitted to the Analytical of Ambiguity technique. Results From the analysis of the experiential descriptions, two categories emerged that reveal the significance attributed by students to their experiences in the university context: the university that generates suffering and the university that provides growth. Final considerations Undergraduate Nursing students signify the university context as an ambiguous experience, at the same time that the university is seen as generating suffering, it is also seen as capable of providing intellectual, sociocultural, affective and political growth.

Authors: Rodrigues Martins Alex Sandro , Quintana Alexandre Costa , Gularte Quintana Cristiane
Published: November 2021

The technology incorporation in the academic area results in changes in the way students see the subjects professors teach, as well as interferes with interpersonal relations, contributing to expanding the classroom beyond its physical environment. Therefore, it creates interactive learning environments in which the professor assumes a mediating role. Another consequence of technology insertion in education is the emergence of virtual tools that collaborate with student growth. With the use of the Unified Theory of Acceptance and Use of Technology (UTAUT), this research aims to identify which factors influence the intention of using an application that provides tips for students about the subject discussed in class in the Undergraduate Program in Accounting of a Federal University in southern Brazil.  This is descriptive research with a quantitative approach through primary data.

The problem of modeling unidirectional dynamic remagnetization of electrical steel in periodic modes, in-cluding sinusoidal and non-sinusoidal changes in the average cross-section of the induction sheet, is consid-ered and solved. The relevance of the problem under consideration is determined by the fact that when design-ing semiconductor pulse converters of power supply systems operating in peak load modes, it becomes neces-sary to calculate their characteristics and parameters with a more accurate setting of the magnetic characteris-tics of steel, taking into account the real processes of dynamic magnetization reversal observed in the magnetic circuits of transformers and chokes. The proposed simulation model of dynamic magnetization reversal of a ferromagnet allows us to describe with acceptable accuracy the nonlinear, hysteresis and dynamic properties and characteristics of steel, including hysteresis loops, the main magnetization curves, and losses. The performed modernization of the classical Giles – Atherton(JA) model makes it possible to take into account and approxi-mately describe the eddy currents and magnetic viscosity that appear during dynamic remagnetization. The de-veloped numerical procedure allows you to identify the parameters of the constructed model and configure it. The results of the performed validation of the model using experimental data confirm the possibility of its application to describe the characteristics of electrical steel in dynamic modes of remagnetization.

This article is devoted to development of a method of the digital control systems design with not gaged state variables of the object with uncertain nonlinearity. Application of two observers to find the asymptotic es-timates of the nonlinearity and the state vector of the object is the main feature of the developed approach. The problem of designing is solved on the basis of the discrete-time model of the object with application of the con-trol on output and impacts and the standard normalized transfer functions. It allows to provide the required indicators of quality both in established, and in a transient mode. The numerical example illustrates effectiveness of the developed method. The obtained results can be used to design of digital control systems which can significantly increase effectiveness of the controlled objects as production and special assignment.

The article deals with improvement off the efficiency of external and traction power supply systems using for example indicators of traction substations for a real electric transmission line segment of a traction network of 25 kV. The analysis of the functioning of a real section of electrified railways with traction substations, two of which are connected according to the "feeding" scheme is providing in the article. The currents in the wind-ings of traction transformers are calculate for these substations. The proportion of the currents values of the most loaded winding to the two less loaded is 2: 1. The coefficient asymmetry of currents of transformer wind-ings operating on existing traction substations is equal to 1. The results prove a significant currents asymmetry of transformers windings and phases of electric transmission lines which leads to an increasing voltage unbal-ance. New schemes for connecting traction substations for the considered section of electrified railways have been developed in order to improve the quality indicators of electrical energy. New connection schemes for three traction substations, determined according to the requirements for connecting to the external and trac-tion power supply system are presents in the article. The calculation for new schemes of connecting traction substations, similar to the previously considered option, has been performed. The values of winding currents, power transmission line phases and coefficient asymmetry were obtained for new substation connection schemes. The proposed schemes for connecting traction substations provide a decrease in the coefficient asym-metry of the winding currents from 1 to 0.5 and a decrease in the current modulus in the most loaded windings by 1.5 times. New schemes for connecting traction substations reduce the currents of the most loaded windings and phases of the power transmission line, as well as the asymmetry of currents, which ensures an improvement in the efficiency of the external and traction power supply systems of the real traction network.

Published: November 2021

Objective

Obesity is one of the most challenging diseases in

orthopedic surgery which directly affects the clinical

results of the operations. Many studies in the literature

demonstrated the effects of obesity on orthopedic

surgery. Anterior cruciate ligament (ACL) rupture

is commonly seen in young and active individuals

and generally treated surgically. In this study, we

had the intention to investigate the effect of obesity

on the clinical results of anterior cruciate ligament

reconstruction.

Material and Methods

180 patients were retrospectively evaluated whom

operated between September 2012 - June 2016. The

patients are divided into 2 groups according to their

body mass index (BMI). All patients were operated

on in a single center and by a single senior surgeon.

BMI30 kg/m2 patients formed the Group 2 (n=67).

Age, gender, BMI of the patients, waiting time for the

operation, preoperative and postoperative Lysholm

and modified Cincinnati scores were compared

between these two groups.A p-value less than 0.05

(typically ≤ 0.05) is statistically significant.

Results

There was no significant difference between the

groups in terms of complication, follow-up periods,

waiting time before operation, and pre-op and postop

Lysholm scores, and post-op modified Cincinnati

scores. A significant difference has been found

between the groups in pre-op modified Cincinnati

scores.

Conclusion

ACL reconstruction surgery has similar results in the

obese population compared to the normal weight

population in terms of functional further studies and

other parameters are needed to verify these results.

This article analyzes the sanitaryparasitological and sanitarybacteriological state of the soil of the Astrakhan region for 2015 to 2019. In total, 7587 soil samples taken from various environmental objects were studied, and 18.197 studies have been performed. Of the samples, 333 (4.4%) samples did not meet the hygiene standards. For parasitic purity, 4566 (60.2%) soil samples were examined, and 9132 (50.2%) studies have been performed. The largest number of soil samples were collected and examined in 2015 and 2016, which amounted to 943 (20.7%) in 2015 and 1046 (22.9%) in 2016. The number of samples that do not meet hygienic standards was 62 (6.6%) in 2015 and 91 (8.7%) in 2016. In 2015, the positive findings were helminthiasis caused by unfertilized eggs of Ascaris lumbricoides (4 [0.5%]), eggs of Toxocara canis (37 [3.9%]), and larvae of Strongyloides stercoralis (21 [2.2%]). For microbiological indicators, the largest number of soil samples were collected and examined in 2019 and amounted to 694 (23.0%), of which positive findings in the form of common coliform bacteria of Escherichia coli amounted to six (0.9%). Studies for bacteriological indicators in 2016 have used 662 (21.9%) samples, which is 0.9 times less than the samples taken in 2019. The sanitary condition of the soil of the Astrakhan region remains stably tense, as evidenced by positive findings in the form of eggs and larvae of helminths, as well as pathogenic bacteria of Escherichia coli. The presence of ascarid eggs, toxocars, and strongylid larvae in the soil indicates contamination of these objects with the feces of infected people and animals. The presence of coliform bacteria of Escherichia coli in the soil also indicates contamination with the feces of sick people.

This study presents the results of the examination of potential donors of blood and its components for immunoglobulins M and G to patients with coronavirus disease 2019 (COVID-19) living in St. Petersburg. A total of 6782 people aged 1824 years were evaluated, which accounted for 2.07% of the regions population (326 760 people) of this age group. The study was carried out in the spring and autumn of 2020. A negative result (absence of antibodies) was obtained in 93.5% of the participants. The rates of immunoglobulins M and M + G were 0.58% and 4.18%, respectively, in the spring and autumn. Moreover, the number of participants who had immunoglobulins M and G + M in the autumn period was four times higher than the indicators of the spring period, which indicated greater infection activities in the population during this period. This is most likely due to the active movement of the population in the summer. When comparing the rates of COVID-19 infection and the frequency of occurrence in donors of the same age, markers of human immunodeficiency virus 1 and 2 and hepatitis B and C in 2020 (0.024, 0.012 and 0.13%, respectively) indicate the urgency of the problem of donor selection during blood services, especially during a difficult epidemiological situation because of COVID-19. Along with organizational measures for the selection of donors (e.g., attracting individuals from organized groups in which there are no signs of an unfavorable epidemiological situation to donation), mandatory testing of potential donors for immunoglobulins M and G should be considered.
