Wind conditions for snow cornice formation in a wind tunnel
Authors: Yu Hongxiang , Li Guang , Walter Benjamin , Lehning Michael , Zhang Jie , Huang Ning
Published: February 2023

Abstract. Snow cornices growing on the leeward side of mountain ridges are common in alpine and polar regions during snow seasons. These structures may crack and fall, leading to an increase in avalanche danger. Although cornice formation has been observed in wind tunnel tests and the field, knowledge gaps still exist regarding the formation mechanism. This is particularly true with respect to wind conditions which favor cornice formation. To characterize the wind effects as the main factor for cornice growth, we carried out ring wind tunnel (RWT) experiments in a cold laboratory under various wind conditions. We quantitatively investigated the growth rate of the cornice in the horizontal and vertical direction as well as the airborne particle concentration. The results show that cornices only appear under a moderate wind speed range (1–2 times the threshold wind speed). The cornice growth rates in length and thickness are mainly determined by the combined effects of mass accumulation and erosion. The lower-limit wind speed for cornice growth is approximately equal to the threshold wind speed for snow transport. The upper limit of wind speed is when the erosion rate is higher than the deposition rate. The length growth rate of the cornices reaches a maximum for wind speeds approximately 40 % higher than the threshold wind speed. Moreover, a conceptual model for interpreting the cornice accretion mechanism is proposed based on the mass conservation and the results of the RWT experiments. The estimated suitable wind condition for cornice growth and formation are in good agreement with field observations in Gruvefjellet, Svalbard. Based on the physics of drifting snow, our results provide new insights into snow cornice formation and improve understanding of cornice processes that can influence avalanche activity. The experimental results and the conceptual model can be used in future snow cornice simulation and prediction work for cornice-induced avalanches.
La expresión de emociones en la narrativa de los adultos mayores con deterioro cognitivo leve o moderado: Análisis e intervención metalingüística
Authors: Mendizábal de la Cruz Nieves , González Martín Enrique
Published: February 2023

Las emociones constituyen una parte esencial del ser humano a lo largo de todas las etapas de su vida. En este trabajo estudiamos la expresión de emociones en el discurso oral de 23 adultos mayores (16 mujeres y 7 hombres) de entre 75 y 95 años, diagnosticados con algún deterioro cognitivo por diversas enfermedades, tomados del corpus “Metalenguaje y envejecimiento” (Mendizábal, González, Jimeno y Sánchez, 2022). El objetivo es describir y analizar las estrategias de expresión de emociones positivas y negativas ilustradas con ejemplos y establecer la proporción de emociones expresadas según el sexo y la edad. Para la clasificación de emociones se ha partido de estudios previos (Rusell, 2009; Sander, 2013; Lazarus, 2001) pero adaptados al tipo de entrevista semiestructurada para la extracción de datos. El análisis de expresión de emociones en los informantes que constituyen el corpus pone de manifiesto carencias de tipo léxico y gramatical que les impiden expresar de manera más eficaz sus emociones, especialmente las negativas. Los resultados obtenidos del análisis nos conducen a la elaboración de una intervención logopédica específica para que la población mayor con deterioro cognitivo leve tenga una competencia comunicativa que le sirva para manifestar de forma óptima sus sentimientos y emociones.
What counts as contribution? Micro-practices of enrolment and exclusion in a financial problems support group
Authors: Wilson Anna , De Paoli Stefano , Rough Daniel
Published: February 2023

This paper explores the micro-practices of participants in an online community and the relationship between these practices and different metrics of contribution to the community. It compares contribution metrics derived from two different measurement technologies, one based on a conventional, individualistic algorithm and one on whole-part relationships. We combine an Actor-Network theoretical perspective with empirical research that employs both social network analysis techniques and detailed, qualitative analysis of discussion forum activities and exchanges between participants. Together, these approaches allow for a detailed tracing of the discussion forum network. We find that the two different technologies of measurement enact different versions of contribution (and hence reputation). Because of this, they identify different actors as influential in the discussion forum actor-network (although there is some overlap). However, neither effectively distinguishes between actors that tend to enrol others into or exclude them from the actor-network; and thus neither reliably identifies those whose actions align with the actor-network’s aims.

Published: February 2023

Nearly every modern Olympic Games has brought astonished comments and criticism of the body sizes of female gymnasts. The comments from laypersons, scientists, journalists, and physicians too often imply that these diminutive athletes are unusually small and possibly unhealthy. Purpose: An extended and updated analysis of the sizes of U.S. female Olympic gymnasts including the 2012 and 2016 Olympic Games. Methods: Official public records from the US Olympic Committee and USA Gymnastics of Olympic team members were assessed including height, mass, age, body-mass index (BMI) and team performance rankings. Sixteen Olympic teams with a total of 123 team positions including the alternates were assessed. Trend analyses were conducted using linear and polynomial models. Results: Analyses indicated that since 1956, height, mass, age, and BMI declined at first and then increased, with the exceptions of height and rank. Best regression fits were obtained via 2nd order polynomial equations. Height and rank showed a downward trend throughout the historical period. Conclusion: Female Olympic gymnasts were getting smaller through approximately the 1980s and early 1990s. An upward trend in size variables was then observed through 2008. The addition of the 2012 and 2016 Olympic Games data showed that height shifted to a decline from a slight upward trend, and rank continued to decline throughout the historical period.
APPARATUS DIFFICULTY IN RHYTHMIC GYMNASTICS ROUTINES – COMPARISON BETWEEN 2 OLYMPIC CYCLES
Authors: Leandro Catarina
Published: February 2023

The aim of this study was to analyze the evolution of the apparatus difficulty in Rhythmic Gymnastics gymnasts in 2 Olympic cycles and identify eventual factors that could contribute to improve the performance quality in competition. We studied the value of the apparatus difficulty in the gymnasts (potentially the gymnasts could participate in the Olympic Games) of the first World Championships of each cycle (2012/2016 e 2016/2020). This analysis focused on the technical value of the apparatus difficulty performed by the   gymnasts in a total of 288 competition routines in the World Championships 2013, and 200 competition routines in the World Championships 2017. The data was treated using the descriptive statistics and after checking the normality of the data distribution using the Kolmogorov-Smirnov test we used a t-test to determine whether there were significant differences between the World Championships. 

Results showed an increasing appreciation of the apparatus difficulty in the final score of the gymnasts. The apparatus difficulty elements were significantly increased from one cycle to the other, mainly due to the increase of the Mastery value. There’s a greater balance in the use of different elements, giving privilege to the apparatus technique. The increase on the value of the apparatus difficulty in the RG competition routines will contribute for the quality and diversity of the RG competition in the Olympic Games
BRAZILIAN OLYMPIC GYMNASTS’ PERSPECTIVES ON THEIR PARTICIPATION IN THE OLYMPIC GAMES
Authors: Schiavon Laurita Marconi , Locci Bruna
Published: February 2023

This paper analyzes the perspectives of Brazilian gymnasts on the experience of participatingin the Olympic Games (OG) in the Women’s Artistic Gymnastics (WAG) competition (1980-2004), using oral history in a qualitative research approach, and cross-sectional thematic analysis. The author interviewed ten Brazilian WAG gymnasts (100% of the sample) who participated in OG until 2004. The gymnasts’ testimonials indicated that, as the Brazilian WAG team improved their performance in international competitions, gymnasts’ expectations have changed over time, although the dream to participate in the OG was shared by all of them. From the generation of the pioneering gymnasts (1984-1988-1992) to the transitional generation (1996-2000), it is possible to observe several differences related to the pressure to perform well in the competition. While the pioneering gymnasts were not concerned about their ranking in the OG, the transitional gymnasts were reminded of the responsibility to represent their country. For the new generation gymnasts (2004), the participation in the OG carried the burden of needing to accomplish something, to be among the best gymnasts in the world, with actual chances of going to the finals and getting medals in the apparatus finals. Testimonials show their confidence in the work developed by the experienced Ukrainian coaches who led the Brazilian team in the OG in Athens. Gymnasts describe their experience in the OG as having accomplished a mission, feeling at the same time relief, disappointment, desire to return to other editions and some even report the sensation of being lost after returning to Brazil.
DO WOMEN’S TEAM MEMBERS COMBINED CAREER DURATIONS IN THE OLYMPIC GAMES AND WORLD CHAMPIONSHIPS INFLUENCE TEAM OUTCOMES? A HISTORICAL EXAMINATION – 1936 TO 2016
Authors: Sands William , Donti Olyvia
Published: February 2023

U.S.A.’s Women’s Gymnastics team has performed exceptionally at the Olympic Games and World Championships in recent years.  One of the aspects of performance thought to be important in team events is the prior experience of the athletes.  Prior experience can be measured by an athlete’s total number of world level competitions and career durations prior to a given competition.  Olympic and World Championship team rosters and team ranks were examined from 1936 to 2016.  The number of competitions per athlete and ranks of the teams were tallied and analyzed over the entire period.  There were 193 individual athletes and 43 competitions.  Athlete career durations were determined by calculation of years between competitions in which the athlete participated.  Time-series regression analyses showed no relation between career durations and time while there was a statistically significant trend of team rank reduction (better team finishes) over time.  After dividing the study period into two-time segments, there were no statistical differences between early and late periods in career durations, while there were statistical differences in team ranks over the same durations.  Olympic Games and World Championships were separated and again there was no statistical difference between the two competition levels on career durations nor did the ranks of the two periods show statistical differences.  There did not appear to be a relationship between career durations and team performance ranks.

Authors: Kounsar Hina , . Rameez
Published: February 2023

Aim: To study the pattern of keratoconus including age, sex, and risk factors such as eye rubbing, UV exposure.
Material And Methods: Retrospective hospital based study including 437 diagnosed patients of keratoconus in the year 2022.
Results: In our study the prevalence of keratoconus was 0.5%. The mean age of keratoconus patients in our study was 25.67 years. Males (54.7%) were affected more than females (45%). Maximum number of cases were from Srinagar followed by Pulwama and Budgam districts. Most of the patients gave itching and eye rubbing as a symptom and were associated with VKC.
Conclusion: We believe that the prevalence of keratoconus in Kashmir is way beyond which is diagnosed. This is because of the lack of proper investigative tools. The number is just the tip of iceberg which we got in our hospital. Moreover, eye rubbing, VKC and UV exposure has been the most important risk factor.

Published: February 2023

The various bits of intelligence of elementary school-age children can be explored and developed. This diverse intelligence is known as multiple intelligence. Student Worksheets based on multiple intelligences can be used for thematic learning so that students become more active and enthusiastic in participating in learning. The results of observations and interviews conducted before the research showed that the teacher had never made student worksheets and only used student worksheets in student thematic books. Students also never use multiple intelligence-based student worksheets in learning. This study aims to develop various intelligence-based student worksheets in thematic learning to improve students' numerous intelligence abilities. This study uses research and development (R&D) methods. This research was conducted at MI Baitul Huda Semarang, Central Java, Indonesia, with a total of 65 students. The results showed that (1) multiple intelligence-based student worksheets in thematic learning were developed based on an analysis of the needs of teachers and students. (2) the results of the assessment of the two students worksheet validators were 90.4% and 92.3% on every feasible criterion. The assessment from psychologists was 93.8% with very appropriate criteria, (3) the effectiveness of multiple intelligence-based student worksheets was assessed from the N-gain test with a result of 0.83 with an effectiveness percentage of 83. The results of the hypothesis test showed that t count (17.957) > t table (2.036), (4) the acceptability of multiple intelligence-based student worksheets is assessed based on teacher and student response questionnaires with a percentage of 87.5% and 97.5% on every feasible criterion.

Monkeypox is an evolving zoonotic disease which is caused by the monkeypox virus. In the recent times the number of cases across the globe has increased. The disease was previously endemic to Africa but is now spreading worldwide. More than 62,000 cases were reported across 104 countries. The illness typically has an incubation period of 7 to 14 days and symptoms such as fever, headache, fatigue, myalgia, generalized body aches, lymph node enlargement, and skin lesions are common. Monkeypox is similar to smallpox, but lymphadenopathy is the characteristic feature of monkeypox. Due to the numerous illnesses that can produce skin rashes, it may be challenging to distinguish monkeypox solely based on clinical presentation hence individuals suspected with monkeypox infection should be tested for the virus. Diagnostic tests are essential for determining the presence of an orthopoxvirus infection. When these tests are paired with clinical and epidemiological data, such as a patient's history of vaccinations, they are most effective. Surface lesions and/or skin materials like crusts and exudate swabs are good samples for diagnosis. Nucleic acid amplification testing, such as real-time or classical polymerase chain reactions, is used in the laboratory to confirm specimens from suspected cases. Clinical and epidemiological data should be taken into account when monkeypox infection is confirmed. Further research is needed to develop preventive strategies to minimize the spread of the disease. The purpose of this research is to review the available information about an epidemiology, clinical manifestations, and diagnosis of monkeypox.

Oral mucositis is a frequent adverse effect of cancer treatment that includes radiotherapy (RT) and chemotherapy (CT). It is related to worse outcomes because of pain, nutritional problems, effects on quality of life, changes in cancer treatment, the risk of infection, and financial costs. It affects 20% to 80% of people receiving chemotherapy, and almost all patients receive head and neck radiation therapy. This review presents the current understanding and discusses evidence-based clinical management strategies for oral mucositis. The current model of mucositis pathogenesis is comprised of five broad stages. The two widely used grading systems for routine clinical care and research on mucositis are the WHO (World Health Organization) and Oral Mucositis Scale and the National Cancer Institute's Common Toxicity Criteria (NCI-CTC). The effective use of assessment scales, nonpharmacologic treatment modalities such as good professional oral hygiene, cryotherapy, and photobiomodulation, and pharmacologic therapies such as KGF-1 (palifermin) and benzydamine-containing mouthwash are important for mucositis prevention, and topical morphine is effective for the treatment of mucositis induced by radiotherapy or chemotherapy. Mucoadhesive hydrogel and anti-inflammatory medications such as celecoxib, misoprostol, and rebamipide are reported to be effective for radiation-induced mucositis. However, additional experimental studies are required to confirm the evidence.

Globally, colorectal cancer is one of the most prevalent cancers and following sphincter-preserving procedures for rectal cancer, many patients experience various forms of bowel dysfunction. Low anterior resection syndrome (LARS), which has a detrimental effect on the patients' quality of life, is the most common form in which bowel dysfunction presents and is a frequently reported complication of rectal cancer surgeries. Assessment of LARS severity requires a thorough history taking, physical examination of the patients, use of validated questionnaires, and other diagnostic techniques. The clinical manifestations of LARS can be categorized into two groups. The first includes increased frequency, incontinence, and fecal urgency. The second category includes issues with bowel emptying, incomplete eviction sensations, and constipation. Some patients describe traits from both categories, either switching back and forth between the two patterns or experiencing both at once. Each patient's LARS treatment should be tailored as per need. Patients with major LARS typically require multimodal therapy to achieve acceptable results. Treatment options include minimally invasive techniques as well as conservative care such as pharmacological management, pelvic floor rehabilitation, and transanal irrigation. Fecal diversion might be required if this treatment is unsuccessful. Appropriate Kegel exercise of the anal sphincter and initial precise dissection with preservation of nerves and development of a neorectal reservoir after anastomosis can limit the occurrence of LARS. For patients who have LARS risk factors, pretreatment counselling is a crucial step. The purpose of this research is to review the available information about clinical manifestation and treatment of LARS.

Overcrowding in emergency departments is a significant challenge in the world of medicine. Approximately 90% of the emergency departments face the issue of overcrowding. The causes of the phenomena are intensely contested, which makes it challenging to come up with effective, focused solutions. Individual patients, healthcare systems, and entire communities are all impacted by emergency department overcrowding. Crowding's detrimental effects on the delivery of healthcare services lead to delays, subpar care, and inefficiency, all of which have an adverse impact on the health outcomes of emergency patients. The purpose of this research is to review the available information about factors and solutions addressing overcrowding in emergency departments. Increased number of patients arriving in the emergency department, lack of resources, and the number of admitted patients waiting for transfer from the emergency department to a hospital ward are all contributing factors to the problem of overcrowding in the emergency department. The quality of medical care is directly impacted by emergency department overcrowding, which causes medication to be administered later than intended and raises the risk of morbidity and mortality among hospitalized patients. It also contributes to a number of unintended issues, including increased duration of waiting times, a decline in patient satisfaction, and a loss of revenue for medical facilities. Additional staff, observation units, hospital bed access, non-urgent referrals, ambulance diversion, destination control, congestion controls, and queuing theory are some of the possible solutions to overcrowding. Effective implementation of the strategies managing overcrowding at emergency department is needed.

Published: February 2023

A 32-year old woman, gravida 1 para 0, was referred to Seoul St. Mary’s Hospital for fetal cardiac mass by ultrasound at 38 weeks of gestation from a local obstetric office. Detailed fetal echocardiogram was performed and the presence of multiple cardiac tumors was observed, suggesting rhabdomyoma. After birth, fetal echocardiography and genetic screening were performed. A targeted Sanger sequencing analysis was performed for TSC1 and TSC2 genes. Molecular analyses revealed a heterozygous gene variant with a novel frame shift mutation in TSC1, confirming the diagnosis of Tuberous Sclerosis (TSC). A segregation study of the causal mutation was performed by Sanger sequencing for both parents, revealing no mutation in either parent. Thus, the novel frameshift mutation occurred de novo. For fetuses with suspected cardiac rhabdomyoma identified by ultrasound, perinatal genetic testing for TSC should be performed for both the fetus and family members for early detection, early diagnosis, and better prognosis. Early diagnosis of TSC can provide greater opportunities for infants to obtain timely neonatal treatment and better outcome.

Published: February 2023

Intramedullary Osteosclerosis (IMOS) is a rare idiopathic dysplasia of the long bones shafts. IMOS remain an un known diagnosis because of its rarity and the absence of specific features. Indeed, the diagnosis of IMOS can be confirmed only after excluding other differential diagnosis of osteosclerotic lesions. We report here a case of IMOS of the tibia shafts, diagnosed in a 53-year-old man. Medical history did not reveal a history of trauma or infection or familial bone disease and all other causes of osteosclerosis were excluded. The X-Rays showed extensive sclerotic intramedullary lesion of the tibia shafts, cortical bone thickening, and narrowing of the medullary cavity. No periosteal reaction or soft-tissue abnormality or fracture line were noted. The radiological signs were not pathognomonic, but the clinic, biology, histology, as well as the absence of medical or family history strongly suggested the diagnostic.

Published: February 2023

As the COVID-19 pandemic continues, the number of patients presenting to dermatology clinics with hair loss is increasing. Little is known about the specifics of telogen effluvium affecting this patient population. We aimed to discover patterns in patient characteristics and clinical course in those with telogen effluvium secondary to COVID-19 infection. We accomplished this by collecting patient history, physical exam, and images on patients presenting to our rural Missouri dermatology clinic with COVID-induced telogen effluvium from July 2020 through March 2021. Of the 19 patients identified, 95% were female, mean age was 56 years, mean onset of hair loss following COVID-19 diagnosis was 2.73 months with a range of 2 weeks to 6 months, and 32% of the patients had been hospitalized from COVID. Furthermore we explore possible pathogenesis behind and special considerations regarding counseling for COVID-induced telogen effluvium. We have concluded that telogen effluvium can occur following both severe and mild COVID-19 infections, may present earlier than TE associated with other causes, and requires unique patient counseling and follow-up given the psychological impact of both COVID-19 and telogen effluvium. Clinicians should be familiar with the unique characteristics of COVID-induced telogen effluvium and how to appropriately manage these patients.

A 52 year old woman having bronchiectasis, presented to us with worsening cough which was productive with profuse, foul smelling sputum of a week’s duration. A clinical diagnosis of infective exacerbation of bronchiectasis was made. She was started on antibiotics based on her previous sputum culture sensitivity reports. She was asked to collect an entire day’s sputum in a transparent container which demonstrated the classical three layer sputum (Figure 1). Her high resolution CT scan of the thorax was suggestive of cystic bronchiectasis, predominantly involving the right lung (Figure 2). Some of the cysts contained fluid levels also, indicating active infection.

En esta investigación se analizaron parámetros físico–químicos y microbiológicos de la leche cruda de vaca, para evaluar su calidad–inocuidad con referencia a la normativa técnica ecuatoriana (INEN009–2012), y a las normativas de otros países: Perú, Colombia, Venezuela, México y Argentina. Se tomaron 203 muestras de leche cruda contenidas en medios de transporte provenientes de 6.214 productores, al ingreso a 28 centros de acopio de la provincia de Cañar, Ecuador. Se realizaron análisis in situ de temperatura, densidad y acidez titulable, mientras que grasa (G), sólidos totales (ST), sólidos no grasos (SNG), proteínas (P), punto de congelación (PC), Conteo de Células Somáticas (CCS), Conteo de Bacterias Totales (CBT), aerobios mesófilos y enterobacterias se realizaron en laboratorios de AGROCALIDAD y de la Universidad de Cuenca. Se observó que en las variables: densidad (15 °C), acidez titulable, G, ST, SNG, P, PC (°C); el 87,5 al 100 % de muestras cumplen, tanto con la normativa ecuatoriana como con las normativas de los países analizados. Las normativas de Colombia y Venezuela tienen valores referenciales más exigentes para densidad, proteína, acidez titulable y SNG, respectivamente. México y Argentina no hacen referencia para ST y Perú no considera proteínas. Sin embargo, los resultados en microbiología son desalentadores, del recuento de aerobios mesófilos solo 8 % de muestras analizadas cumplen la normativa de todos los países. La carga microbiológica es alta, a pesar que ninguna normativa analizada indica máximos para CBT, se encontró una media de 24.000 × 103 unidades formadoras de colonias por mililitro (UFC·mL–1). Como referencia, algunas normativas en EUA fijan un máximo de 300 × 103 UFC·mL–1 de CBT en leches mezcladas. Este trabajo aporta un conocimiento del estado actual de la calidad–inocuidad de la leche cruda de una importante zona lechera del Ecuador y analiza estos resultados en el contexto de normativas internacionales, sirviendo para focalizar esfuerzos en la mejora continua con miras a la exportación.

Como abordagem metodológica, utilizou-se a pesquisa no campo da História da Educação, mais especificamente a análise documental em fontes primárias, a biografia no contexto historiográfico e a análise de imagens como fontes de pesquisas históricas. Como resultado mostra vasta documentação histórica em que é possível traçar a trajetória destas mulheres, além de trazer contribuição para a história da Química no Brasil. Inah faleceu prematuramente, Maria da Conceição mudou de área por não conseguir seguir carreira na área da Química e se tornou a primeira pessoa a defender tese de doutorado em Geografia na USP, e Hilda, que foi a única das três que conseguiu superar a barreira do mercado de trabalho, e atuar como Química na Secretaria da Agricultura do Estado de São Paulo, onde realizou diversas pesquisas, participou de negociações com a Organização das Nações Unidas para a Alimentação e a Agricultura (FAO), e ainda publicou livros e artigos em jornais. A pesquisa dá luz a novas referências femininas na história da química nacional e ajuda a construir uma narrativa não masculina para a ciência brasileira.
Decolonizing Churches
Authors: Arenas Sandra
Published: February 2023

The Ecclesiological Investigations International Research Network gathered in San Juan, Puerto Rico, in June 2022 to discuss the issue of “decolonizing churches” from ecumenical, intercultural, and interdisciplinary perspectives. And, although the place was chosen for a number of reasons, one of the main ones was that the Caribbean context and especially the island of Puerto Rico contributed to further problematize the colonize-decolonize binomial within ecclesial and theological coordinates. This article captures the main insights gained throughout the whole academic meeting as well as the stumbling blocks for decolonizing churches and the challenges that ecumenical theology faces.

Aim: To study the prevalence and response to needle-stick injuries in a tertiary care hospital. Study design: Cross-sectional study Place and duration of study: Dept. of Gen. Surgery, Hayatabad Medical Complex Peshawar from 01-06-2020 to 30-06-2022. Methodology: One hundred and ninety three healthcare workers were recruited, including doctors, medical students, nurses, student nurses and paramedics. Results: There were 60(31.1%) healthcare workers reported needle stick injury. Majority of the injuries 51(85%) occurred during contact with patients who were assessed as not high-risk and 9(15%) when exposed to high-risk patients. Most of responders 49(81.7%) reported that the injury was self-inflicted and 11(18.3%) reported that it was caused by someone else. About 45(75%) injuries were caused by hollow bore needle and 15(25%) by a solid needle. Most of the needle stick injuries occurred at the bedside 50(83.4%), 8(13.4%) in the operating theatre and 2(3.4%) were at other locations. Conclusion: Needle stick injury is a significant cause of physical and psychological morbidity among healthcare personnel. Proper training and strict protocol for following the standard precaution can minimize its incidence. To improve its reporting the procedures of reporting a needle stick injury could be simplified.

Aim: To identify the association of vascular endothelial growth factor (VEGF) immunoexpression in the progression of salivary gland tumor. Study design: Comparative cross-sectional study Place and duration of study: Department of Pathology, Peshawar Medical College. Duration of study was six months from date of approval. Methodology: Forty five specimen of salivary gland tumor were studied in which 30 were benign and 15 were malignant. The endpoint assessment included Hematoxylin & Eosin (H&E) and VEGF immunoexpression. Results: The association of VEGF expression with salivary gland tumor was statistical significant (P<0.05). Maximum 18 samples (benign: 13, malignant: 5) were shown to have strong expression, 24 (benign: 16, malignant: 8) were shown moderate expression. Whereas, small and no expression was found in 2 (benign: 0, malignant: 2) and 1 (benign: 1, malignant: 0) sample, respectively. Conclusion: Overexpression of VEGF in both malignant and benign salivary gland tumors might be associated to progress salivary gland tumors.

Los Círculos de Obreros y la cuestión social en la ciudad de Buenos Aires
Authors: Asquini Sabrina E.
Published: February 2023

A fines del siglo XIX el auge reivindicativo del movimiento obrero puso de manifiesto en el escenario social y político argentino la existencia de una cuestión social. En sintonía con los planteamientos de la encíclica Rerum Novarum (1891), los Círculos de Obreros organizados por el padre Federico Grote se orientaron a intervenir en las filas del movimiento obrero para re-encauzar su conducta y alejarlo de movimientos de lucha. El presente trabajo se ha propuesto repensar su orientación y métodos a partir de la interpretación que los organizadores de los Círculos de Obreros hicieron de la situación social de las masas obreras de fines del siglo XIX en los primeros años de su actividad. Dada la escasez de documentos propios de los Círculos en dicho período, nuestro objetivo es reconstruir sus posiciones a la luz de la polémica sobre la cuestión social que entablaron con el socialismo en 1895.
Orden Cristiano ante la cuestión social (1941-1948)
Authors: González Warcalde María
Published: February 2023

El presente artículo explora los aportes intelectuales en torno de la acción social cristiana en una revista quincenal de raigambre liberal, antifascista, antiperonista y católica, titulada Orden Cristiano (1941-1948). En un contexto en el que la justicia social se constituyó en un discurso operativamente dinámico, la legitimidad de la acción social cristiana en la publicación se reforzó a través de tres mecanismos, los cuales constituyen los ejes de análisis del trabajo: la apelación a principios abstractos, la referencia a organizaciones y la recuperación de itinerarios de individuos

En el siguiente trabajo se aborda la experiencia del grupo de ex-alumnos del colegio salesiano de la ciudad de Córdoba (Argentina) durante las primeras décadas del siglo XX, como un ejemplo del activismo laical en el mundo católico previo a los años treinta. A través de un fuerte compromiso militante, los Centros de Ex-alumnos de Don Bosco funcionaron como espacios de sociabilidad al tiempo que ocuparon un rol activo como dinamizadores de los sectores católicos de la ciudad, con una importante presencia en la escena pública local.
Católicos en las calles
Authors: Mauro Diego , Ramón Solans Francisco Javier
Published: February 2023

Paradigma de las ensoñaciones del progreso, aquellas bulliciosas ciudades de comienzos del siglo XX fascinaron a sus contemporáneos. Las multitudesque diariamente las atravesaban fueron objetos de sinfonías fílmicas como el Berlin: Die Sinfonie der Großstad (1927) de Walter Ruttmann. Incluso los mecanismos narrativos de las novelas se modificaron para dar cuenta de la multiplicidad de voces que se escondían en aquellas vibrantes ciudades como enel Manhattan Transfer (1925) de John Dos Passos o en el Berlin Alexanderplatz (1929) de Alfred Döblin. El carácter de estas gigantescas urbes también generóreflexiones y respuestas en el marco del catolicismo. La moderna ciudad fue vista como una nueva Babilonia, un terreno de tentación y descontrol,de corrupción moral. Al mismo tiempo, desde el otro lado de la “trinchera”, los anticlericales vieron en ella el triunfo de sus ideales, el desmoronamientodel imperio religioso sobre las conciencias del ser humano. Esta visión de la ciudad como espacio secular fue reproducido en las ciencias sociales porla clásica tesis de la secularización que pasaría a asociar irremediablemente declive religioso con urbanización.
