Published: March 2023

This paper presents research related to the estimation of the precipitation fraction in the soil water of a sloped vineyard at the SUPREHILL Critical Zone Observatory (CZO) in Zagreb, Croatia. Numerous investigations have shown that exploration of hillslope soils can be very challenging due to the existence of heterogeneity and different soil properties, as well as due to anthropogenically induced processes, which can affect precipitation infiltration and soil water flow. Within this research, physicochemical soil properties, soil water content (SWC), and isotopic composition of soil water and precipitation (δ2H and δ18O) have been examined. The isotopic signature of soil water was monitored in 24 points, at 4 depths, throughout the hillslope vineyard. Soil water isotopic composition from all monitoring points coincided with the Local Meteoric Water Line (LMWL), with almost no variability at 100 cm depth, which was consistent with the smallest variation of SWC at 80 cm depth and indicated that most of water mixing takes place in the shallower part of the hillslope. Results suggested the existence of heterogeneity, uneven erosion processes in the footslope of the observed vineyard, and different infiltration patterns. Fractions of precipitation varied significantly depending on the depth and position in the vineyard, from approximately 1% up to 98%, where more precipitation fraction has been determined in the surface and subsurface runoff. Additionally, statistical analysis and a more detailed evaluation of precipitation fractions at the 40 cm depth, where wick lysimeters are installed, have shown that Corg content is related to the silt fraction, while the first results indicate that the infiltration patterns were dependent on the common influence of all observed physicochemical properties.
Optimizing Low Impact Development for Stormwater Runoff Treatment: A Case Study in Yixing, China

Published: March 2023

Low-impact development (LID) practices have been recognized as a promising strategy to control urban stormwater runoff and non-point source pollution in urban ecosystems. However, many experimental and modeling efforts are required to tailor an effective LID practice based on the hydraulic and environmental characteristics of a given region. In this study, the InfoWorks ICM was applied to simulate the runoff properties and determine the optimal LID design in a residential site at Yixing, China, based on four practical rainfall events. Additionally, the software was redeveloped using Ruby object-oriented programming to improve its efficiency in uncertainty analysis using the Generalized Likelihood Uncertainty Estimation method. The simulated runoff was in good agreement with the observed discharge (Nash–Sutcliffe model efficiency coefficients >0.86). The results of the response surface method indicated that when the sunken green belt, permeable pavement, and green roof covered 8.6%, 15%, and 10%, respectively, of the 11.3 ha study area, the designed system showed the best performance with relatively low cost. This study would provide new insights into designing urban rainfall-runoff pollution control systems.
Analysis of Water-Lifting Aerator Performance Based on the Volume of Fluid Method
Authors: Chang Zhiying , Huang Tinglin
Published: March 2023

Water quality deterioration is a major problem faced by reservoirs globally, owing to the inflow of pollution from industrial and municipal activities. Water-lifting aeration is an in situ water quality improvement technology that mixes and oxygenates deep water bodies in reservoirs to improve pollution control efficiency and water quality. While previous studies have mainly focused on the mixing process in the reservoir outside the water-lifting aerator (WLA), knowledge of the internal flow remains limited. In this study, a two-phase flow within a WLA system was numerically studied using the volume of fluid (VOF) method to comprehensively analyze the internal two-phase flow characteristics and the influence on the water-lifting and oxygenation performance of the system. The statistical analysis results showed that increasing the aeration chamber volume enhanced the bottom oxygenation performance by 27% because of the prolonged time of the deflector plate outlet outflow. Additionally, increasing the air release rate enhanced the water-lifting performance by 47%, which was induced by the shortened air piston release period. This study demonstrates the internal flow mechanism of the WLA and provides technical support for parameter optimization design, which has significant scientific research and engineering application value.

Published: March 2023

The 8006 working face at the Wuyang Coal Mine adopts grout injection into bed separation technology for surface subsidence control. Surface grout leakage occurred during the grout injection into the bed separation process of this working face. Grout leakage has adverse effects on the grouting filling effect, grouting cost and the environment. To determine the grout leakage channels and the slurry transport process, and to provide a theoretical basis for slurry leakage prevention and control, this paper first used 3D seismic exploration technology to identify the fault distribution characteristics of the study area, and then used COMSOL Multiphysics to carry out the numerical simulation of the grout transport process. The conclusions are as follows. Fifteen normal faults were identified in the vicinity of the 8006 working face. Among all the faults, the F1, F11, F18, F19 and F27 faults penetrate the surface and are the main channels for the grout to run to the surface. Based on the distribution characteristics of the faults and the spatial location relationship among the bed separation, faults and grout leakage points, the theoretical analysis of the leakage causes of each grout leakage point was carried out, and the main leakage channels of the grout injection into bed separation were proposed to be the bed separation and faults. The results of the numerical simulation of grout transport show that, as the permeability of the bed separation space and fault is much better than that of the surrounding rock, during the grout injection process the grout diffuses through the bed separation and fault in turn, and finally to the surface, where leakage occurs. The simulation results confirm that the main leakage channels for the grout are bed separation and faults.
Determinants of Maternal Mortality in Southern Africa: A Macro-Level Analysis

Published: March 2023

This study sought to investigate the macro determinants of maternal mortality in Southern African Development Community (SADC) states. The study drew on the fact that maternal mortality remains a major public health issue in developing countries. The Millennium Development Goals (MDGs) were adopted by UN member states in 2000, and one of them was to reduce maternal deaths by three-quarters by 2015. While the Millennium Development Goals increased efforts, the goal was not met in the countries with the highest death rates. The World Health Organisation (WHO) estimates that every single day about 810 women die from pregnancy or childbirth-related complications around the world. This is despite several international initiatives being adopted to reduce maternal mortality. The study was quantitative, and it used secondary data to achieve its objective. A panel data estimation (Generalized Method of Moments) covering the period from 2005–2019 was used to examine how various factors affect maternal mortality. The analysis included the following variables: education, fertility, GDP per capita, institutional quality, health expenditure and HIV infection. The econometric analysis reveals a significant positive impact of fertility, GDP per capita and HIV on maternal mortality. This implies that when fertility, GDP per capita and HIV are increasing, maternal mortality also increases. The analysis also showed that education has a negative relationship with maternal mortality. This implies that when literacy levels (education) increase, maternal mortality decreases. Based on the results, this study emphasizes that, in order to improve maternal health and consequently reduce maternal mortality, access to family planning (to reduce fertility), access to early prenatal care and promoting women’s access to education should be a priority in government policies.

In NMRC coloproctology a surgical method of treatment of the fistula of the rectum with the help of highly vascularized lateral flap (VLF) was developed. Currently 28 patients with trans and extrasphincter fistulas are included, both without and with the presence of purullent-inflammatory process in the surrounding tissue. The observation period was 1–8 months (Me = 4 [1.75; 5.5]). The disease relapsed in 6 (21.4 %) cases. Conclusion: the preliminary results of VLF use are encouraging, the low pain intensity and the intactness of the anal sphincter indicate a low traumatic and sphinctersaving nature of the operation. In addition, the study showed the possibility of using VLF even in the presence of purulent accumulations, which were previously contraindications to the use of plastic techniques as a one-stage treatment.

Published: March 2023

Objetivo. Analisar o desempenho de escolares nas habilidades de discriminação de sons e consciência fonológica quanto aos componentes de rima, aliteração, síntese fonêmica e síntese silábica, antes e após uma intervenção musical de consciência fonológica; verificar a generalização das respostas; e analisar a associação das habilidades estudadas com a idade. Método. A ação de intervenção fonológica musical aconteceu em salas com grupos de escolares com idade entre 6 e 10 anos. Foram realizadas avaliações e treinos coletivos por meio de uma bateria de atividades de discriminação de sons e de consciência fonológica. Os desempenhos obtidos nas avaliações realizadas antes e após a intervenção musical foram comparados. Resultados. Após a intervenção fonológica musical, observou-se melhora no desempenho de consciência fonológica das crianças mais novas, com idade entre 6 e 7 anos, principalmente nas habilidades de síntese silábica e fonêmica. Para a habilidade de síntese fonêmica, houve generalização do benefício do treino para os estímulos não treinados. A idade esteve associada ao desempenho de consciência fonológica, exceto à habilidade de síntese fonêmica. Conclusão. A intervenção musical de consciência fonológica melhorou o desempenho das habilidades de síntese silábica e fonêmica das crianças mais novas e proporcionou generalização dos resultados, o que evidencia a importância deste tipo de estimulação das habilidades precursoras da linguagem escrita. Apenas o desempenho de síntese fonêmica não esteve associado à idade das crianças estudadas, portanto, a ação de intervenção destinada a escolares entre 6 e 10 anos influenciou positivamente o desempenho fonológico, reduzindo o impacto da idade.
Del proyecto a los archivos: cambios y estrategias metodológicas en el armado del corpus documental
Authors: García Marisol
Published: March 2023

El objetivo del artículo es mostrar el proceso de conformación de un corpus de fuentes para estudiar la historia de las parcialidades nativas Malfín y Andalgalá en la Gobernación del Tucumán (siglos XVII y XVIII). Me centraré en las dificultades y desafíos de reconstruir su historia a través de documentación fragmentaria y dispersa, reflexionando sobre dos experiencias que pueden resultar ilustrativas para otros investigadores. La primera vinculada al Archivo Histórico de la Provincia de Córdoba, donde la mayoría de las fuentes coloniales se encontraban fuera de consulta, lo que condujo a replantearme el caso de análisis y su delimitación. La segunda gira en torno a un cuaderno manuscrito, inédito, donde Samuel Lafone Quevedo transcribe y comenta documentación histórica sobre Catamarca. Este cuaderno, conservado en el Museo de La Plata, es fotocopiado por Ana María Lorandi quien lo interviene con anotaciones, convirtiéndose en una fuente multívoca que requirió un cuidadoso abordaje metodológico.
Las indias en la política interétnica de Buenos Aires colonial. Documentos y un abordaje metodológico
Authors: Giorsemino María Florencia , García Yésica  N. , Néspolo Eugenia A.
Published: March 2023

El tema de las poblaciones nativas y los vínculos establecidos con europeos invita a repensar preguntas y enfoques de análisis. En tal sentido, la mujer indígena adopta un protagonismo trascendental como objeto de estudio en diferentes espacios y períodos históricos de Latinoamérica. En el espacio rioplatense tardocolonial, específicamente la ciudad de Buenos Aires y su frontera, la mujer indígena se presenta interactuando con diversos sujetos sociales, tanto en el ámbito rural como citadino, enfrentando situaciones de dominación o desarrollando estrategias de supervivencia en los mencionados contextos. Sin embargo, el abordaje presenta sus propias dificultades metodológicas y analíticas. Al respecto, proponemos analizar a las mujeres indígenas y el registro sobre ellas en distintos tipos de documentos coloniales, buscando identificar las situaciones de alteridad y dominación a las que fueron sometidas. Para ello, la herramienta fundamental será la articulación de los diferentes documentos pertenecientes a legajos que se relacionan directa o indirectamente.
Dramaturgia y feminismo en la argentina del siglo XX
Authors: Tarantuviez Susana
Published: March 2023

Este trabajo se inscribe en la construcción de una mirada feminista cuyo propósito es trazar una genealogía de las dramaturgas del siglo XX que han abordado en sus obras las problemáticas de género de su época. Se trata de proponer un recorrido que permita visibilizar no solo la presencia de autoras mujeres en nuestro canon teatral, sino también (y sobre todo) los planteos feministas que vertebran sus textualidades. Por lo tanto, hago hincapié, dentro del universo de dramaturgas argentinas, en una constelación de escritoras que durante el siglo pasado produjeron textos dramáticos en los que la representación de las relaciones de poder en el orden de género, la construcción de las subjetividades femeninas, las luchas por los derechos de las mujeres y la denuncia de las desigualdades entre hombres y mujeres son los ejes de sus poéticas teatrales.

A legitimidade da atuação da Polícia Militar em eventos privados de interesse público
Authors: Angelotti Emídio , Galvão Eduardo Sobrinho
Published: March 2023

O tema da violência pública é sempre recorrente na sociedade brasileira em virtude da persistente insegurança. Neste sentido, faz-se necessário para que se possa combater esse problema buscar suas raízes possibilitando à elaboração de políticas públicas eficientes que atinjam o interesse público. Para o intento desse artigo, buscou-se entender brevemente fatores motivadores de violência em eventos com grande concentração de pessoas. Entretanto, tão importante quanto compreender as causas da violência pública, é necessário também entender como o ordenamento jurídico brasileiro instrui a ação dos órgãos de segurança pública incumbindo-lhes a missão constitucional de buscar combater a mazela da violência, garantindo a necessária ordem pública. Isto posto, buscou-se salientar o relevante papel exercido pela Policia Militar em eventos privados de interesse público, atuando de maneira preventiva, repressiva e utilizando sua expertise voltada à inteligência em conjunto com a segurança privada dos respectivos eventos.

Sharia-based investment is an investment by the community to obtain profits in accordance with Islamic principles and law. This study aims to calculate the optimal portfolio return value using the Single Index Model, calculate risk with VaR (Value at Risk), and then implement it with Matlab’s GUI (Graphical User Interface). The data used is closing stock price data on the JII (Jakarta Islamic Index) using 30 stocks for two consecutive years. Furthermore, these stocks are selected which have a positive average return value. The study results show that 14 stocks are candidates for optimal portfolios with positive return values, namely: ACES, ADRO, ANTM, BRPT, BTPS, CTRA, EXCL, INCO, MDKA, MNCN, SCMA, TPIA, UNTR, and WIKA. Then the optimal portfolio of the 14 stocks is determined using the Single Index Model considering the ERB (Excess Return to Beta) value ≥ cut-off point value (C*). Based on the value, 4 shares were obtained that belong to the optimal portfolio, namely: MDKA, BRPT, BTPS, and ANTM. Furthermore, VaR calculations are performed on the 4 optimal portfolios to obtain optimum VaR consistency values with 500 repetitions. The VaR calculation results with a 95% confidence level show that the average VaR result is in the range of -0.14704 to -0.3420 so that when investors invest in 4 optimal stocks, the losses experienced by investors are no more than 34%.
Las huertas de autoconsumo de la Sierra de Huelva
Authors: García Martín Miguel
Published: March 2023

Diseminadas a lo largo de la Sierra Morena onubense, las huertas de autoconsumo son pequeñas explotaciones agrícolas cultivadas con esmero por los hortelanos sobre todo en los meses de verano. Sobreviven al “supermercado”, ese modelo de producción-consumo agroalimentario basado en llenar la cesta de la compra en una gran superficie comercial. Habichuelas, pepinos, pimientos, melones, sandías... son productos que contribuyen a una dieta saludable al mismo tiempo que ayudan a construir una cotidianeidad en torno a la tierra. De hecho, algunos productos, como el tomate, trascienden sus estrictas funciones alimentarias para convertirse en iconos de unas explotaciones agrícolas con importantes valores patrimoniales, paisajísticos y socio-culturales. Este caso de estudio forma parte del proyecto SAMUTER, que aborda los sistemas agroalimentarios desde una perspectiva territorializada y multidimensional.
La dependencia, la guerra contra las drogas y los solicitantes de asilo mexicanos
Authors:   University of California Riverside, Gonzales Toribio Alfonso
Published: March 2023

Este artículo explica el incremento en el número de solicitantes de asilo mexicanos desde 2001 hasta 2020, puesto que México se ha convertido en el país con el mayor número de solicitudes de asilo en Estados Unidos. Aborda la cuestión desde la perspectiva de la teoría de la dependencia en la que el estatus de México como nación dependiente en la periferia del país más rico del mundo estructura el contexto para que los mexicanos soliciten asilo. A partir de los datos del Centro de Intercambio de Acceso a Registros Transnacionales (TRAC, por sus siglas en inglés), la Oficina Ejecutiva de Revisión de Inmigración, el Departamento de Seguridad Nacional y las estadísticas de las Naciones Unidas y el Banco Mundial, rebato el argumento de los activistas conservadores de que las solicitudes de asilo de los mexicanos están impulsadas principalmente por una estrategia de defensa de la deportación, tras la represión de la inmigración después del 11 de septiembre. Por el contrario, demuestro que los mexicanos huyen de la violencia de la guerra contra las drogas financiada por Estados Unidos en México. Expongo que existe una correlación directa entre la Iniciativa Mérida de 2007 —un paquete de ayuda exterior de 3 mil millones de dólares para la lucha contra las drogas en México—, el aumento de los homicidios y el número de solicitantes de asilo mexicanos.
Migración, informalidad e intercambio desigual en el contexto del proceso de integración regional México-Estados Unidos
Authors:   Universidad Autónoma de Zacatecas, Delgado Wise Raúl , Caballero Anguiano Francisco J. ,   Universidad Autónoma de Zacatecas, Gaspar Olvera Selene ,   Universidad Autónoma de Zacatecas
Published: March 2023

Este trabajo analiza la compleja relación entre migración e informalidad, en el contexto del proceso de integración regional asimétrico y subordinado entre México y Estados Unidos bajo el neoliberalismo. Se argumenta que uno de los principales motores de la migración mexicana contemporánea es la desigual distribución del sector informal —y más precisamente, del ejército industrial de reserva— entre ambos países. En ese sentido, México opera como zona estratégica de reserva y reproducción social de fuerza de trabajo para satisfacer la creciente demanda laboral de Estados Unidos a través de la migración, al revelar que la reproducción del ejército industrial de reserva es esencialmente de carácter transnacional. Se plantea que el principal vínculo entre migración e informalidad desde abajo es a través de las remesas. Además, en el marco de la dinámica de la informalidad desde arriba se desencadena un creciente flujo de migración mexicana calificada y altamente calificada hacia Estados Unidos, en sincronía con el fortalecimiento de la innovación y de las actividades intensivas en conocimiento en ese país.

Authors:   , Streitenberger Nicolás
Published: March 2023

Los objetivos del presente trabajo fueron, determinar la dinámica de infección y circulación de BRSV, BVDV, BPIV-3 y BoHV1 en bovinos de engorde a corral (EC) durante los primeros 60 días de encierre y evaluar la presencia de antígenos y ácidos nucleicos virales en pulmones con lesiones de enfermedad respiratoria bovina (ERB) a la necropsia. Para el primer objetivo se llevaron a cabo tres estudios longitudinales prospectivos (LONG) en los que se realizaron técnicas moleculares y de aislamiento viral a partir de muestras de hisopados nasales y serología seriada. Para evaluar el segundo objetivo se incluyeron muestras de pulmón con lesiones anatomopatológicas de ERB y se realizaron técnicas moleculares y de inmunohistoquímica para detección viral. En los estudios LONG, los mayores valores de seroconversión fueron 80%, 73%, 60%, 67%, 51% y 60% para BRSV, BVDV 1a, BVDV 1b, BVDV 2, BPIV-3 y BoHV1 respectivamente; y todos estos virus fueron detectados, a partir de hisopados nasales, por técnicas moleculares. En animales con ERB clínica (n=6) se detectó BRSV, BVDV, BPIV-3 o combinación de ellos. En los pulmones con lesiones compatibles con ERB, se identificaron los cuatro virus estudiados mediante técnicas moleculares y/o IHQ con porcentajes de detección del 14%,11%, 16% y 5% para BRSV, BVDV, BPIV-3 y BoHV1 respectivamente; mientras que los patrones de lesión pulmonar más frecuentes fueron bronconeumonía fibrinosupurativa y neumonía intersticial. El 23% de los animales con lesiones de ERB presentaron coinfecciones viral y bacteriana. Los resultados de los estudios LONG evidencian circulación de los cuatro virus evaluados en animales con infecciones clínicas y subclínicas de ERB. Las infecciones virales múltiples fueron muy frecuentes y sugieren sinergismo entre los virus. La detección de BRSV, BPIV-3, BoHV1 y BVDV en pulmones de animales de EC con lesiones compatibles con ERB, mediante IHQ y PCR confirmó la asociación entre la presencia viral y el desarrollo de lesión.

Internal Communication Practices Impact on the Institutional Brand During Institutional Transition
Authors: Mtange Margaret
Published: March 2023

Progressive higher education institutions, in a competitive environment, evaluate brand positioning to navigate through communication, economic and globalization challenges. Literature in Sub-Saharan Africa hardly interrogates how public universities manage institutional brand for competitive advantage (Sulkowski, Wozniak, & Seliga, 2019) from an internal communication perspective. In Kenya, rapid university expansion and funding reduction enhanced competition. In a complex and dynamic context, vibrant institutions align corporate strategy to internal communication and position institutional brand. Thus, this study interrogates how the internal communication practices of an emerging university in Kenya impact institutional brand during transformation. A total of 153 Questionnaires were administered and 18 in-depth interviews were undertaken. Data as collected from 18 middle-level management who were purposively selected and the 153 self-administered questionnaires using stratified random sampling were administered on MMU faculty and administrative staff. The findings suggest that effective communication be through employee participation in decision-making (90%), conflict management (73%), brand management (mean 3.3), and corporate storytelling for institutional memory. However, management communication practices did not effectively communicate corporate objectives, marketing and branding strategy during university transition which negatively influenced image building and employee trust. The study recognized the importance of an internal communication policy, during transition, to provide a systematic and structured process which incorporates employee participation and empowerment. Employee participation strategy that integrates induction, interpersonal activities and interactive channels such as social media to communicate institutional strategic elements and enhance relationship management. Empowerment contributes to institutional brand management through mid-manager training, information inclusion, diversity management through internal stakeholder sessions, the use of mediated communication embracing social media, intranet and website to sensitize institutional management and employees. Upcoming public universities, like organisations, are expected to survive and thrive, through strong corporate branding to counter progressive forces arising from global, curricular, policy, technological and generational transformations. The study recommends an internal communication policy and management practice for effective communication of institutional messages to enhance employee participation and empowerment to improve brand positioning during institutional transformation.

El 46% de los pacientes presentaron alteración del perfil hepático, siendo la elevación de transaminasas lo más frecuente. Se demostró que la elevación de la aspartato aminotransferasa (AST) desde el ingreso se asocia a mayor mortalidad.
SURGICAL OUTCOME OF PERCUTANEOUS PIN FIXATION OF PROXIMAL THIRD FRACTURE OF ULNA IN MONTEGGIA FRACTURE DISLOCATION IN CHILDREN
Authors: Raj N Ebel , Ravi Kiran A , PS Amal
Published: March 2023

Introduction: Monteggia fracture dislocation is a rare and severe injury of both paediatric and adult forearm and elbow.It
was described for the rst time by GIOVANNI BATTISTA MONTEGGIA in 1840,who reported two cases of fracture of
the proximal third of ulna with conjoint ventral dislocation of the proximal radius. In 1967 JOSE LUIS BADO published a classication scheme
of monteggia lesion based on the direction of the dislocation of radial head,this anatomical classication was suitable for both adults and children
.Monteggia fracture dislocations constitute about 1% – 2% of all forearm fractures . Monteggia fractures remain challenging paediatric injuries
because of difculties in diagnosis , propensity for instability and complexity of late reconstruction. More than 50% of these fracture dislocation
are misdiagnosed in children and leads to dysfunction of elbow joint. The xation and stabilization of ulna fracture will automatically reduce the
radial head dislocation. The aim of this study is to evaluate a group of paediatric patients with Monteggia lesion and its equivalents treated by
percutaneous xation of proximal third ulna fracture with k wire after reduction of fracture ulna and dislocated radio capitular joint under c-arm
guidance. Materials and methods We treated 18 children of age ranging between 6 to 12 years with Monteggia fracture dislocation of the forearm
with percutaneous xation of the proximal third fracture of ulna with k wires after reduction of fracture and dislocated radio-capitular joint
under C-arm control.The elbow is immobilized in exion with plaster of paris slab and bandage for a period of four weeks and mobilization of

Background CORONAVIRUS disease 2019 (COVID-19) is a viral infectious disease caused by the single-stranded,
enveloped RNA virus, severe acute respiratory syndrome coronavirus-2 (SARS COV-2). Though Covid-19 is an acute
viral infection predominantly affecting the respiratory system, it has short-term, long-term metabolism and endocrine complications. Being a
global pandemic with a high rate of recovery, it is expected to have many long-term metabolic complications in a vast number of covid-19
survivors. We aimed to nd out the post covid complications in patients discha Objective: rged from SARI ward AIIMS Bathinda, Punjab.
Design: Settings: Prospective observational study OPD and telemedicine consultation of the patients admitted to the tertiary hospital Material
and Methods: - A prospective study was done on 244 patients with COVID -19 RAT, and RTPCR Positive patients were done. Patients were
followed up in OPD and by telemedicine for post covid complications. Main outcome measures: The main outcome measures were measured in
terms of mortality as well as morbidity. Morbidity was evaluated in terms of the complications developing after covid or persistence of the
complications developed during the covid. All the patients who were admitted Sample size: to our tertiary Centre were followed for post covid
complications. Result: - Out of 244 patients that were analyzed, 22% died during the disease, and 78% survived. Out of the patient who survived
64.8% developed post covid complications. 35.8% complained of fatigue, 10.5% developed headache, 8.9% developed body aches, 3.2% had a
persistent cough, 1.6% had a sore throat and 1.1% had gastrointestinal symptoms. Conclusion: - In this population-based study large no. of
patients suffer from long-term residual effects afterward-CoV-2 infection such as fatigue, cough, headache, dyspnea, and decline in quality of the
eye. With a large range majority of people infected all over the world, our ndings emphasize the need for timely planning of resources and
patient care. Multidisciplinary collaboration is essential to provide integrated outpatient care for the survival of acute COVID-19. Limitation:
Small sample size
THE THREE KEY PLAYERS IN OSTEOIMMUNOLOGY: RANK, RANKL AND OSTEOPROTEGERIN

Published: March 2023

The RANK, RANKL and OPG interaction plays a major role in bone resorption and remodelling. The history dates back
to mid 1990s when the RANK/ RANKL interaction was found to mediate osteoblastic stromal cells to stimulate
osteoclastic bone resorption. This interaction was found to induce several cytokines including the TNF superfamily, thereby activating the
pathways of bone remodelling. The Osteoprotegerin (OPG) prevents the binding of RANKL to RANK, thereby preventing the excessive bone
resorption. When there is an imbalance in the levels of RANK/RANKL/OPG, the metabolic activity of the bone cells gets altered and thus there is
loss of balance between bone formation and resorption. Thus, studying the inter – relationship between RANK, RANKL and OPG becomes
critical for assessing the osteoblastic and osteoclastic activity.

Published: March 2023

BACKGROUND: The choice of surgery for bilateral inguinal hernia repair still remains a debatable question for
surgeons. This study was aimed at analysing the effectives as well as comparing Lichtenstein, Stoppas and laparoscopic
TEP(total extraperitoneal repair) approaches for Bilateral inguinal hernia. Prospective study invol MATERIALS AND METHODS: ving 60
patients of Bilateral inguinal hernia, were divided into 3 groups, 20 patients each in Lichtenstein, Stoppas and TEP. As per relevant rating scales,
parameters analysed were duration of surgery, post operative pain, post operative analgesia requirement, duration of hospital stay, return to
normal activity, cost effectiveness, surgical complications, recurrence over 6months. Minor complications such as seroma, scrotal RESULTS:
oedema, wound infection were common in Lichtenstein compared to Stoppas and TEP. Shorter duration of surgery, early discharge and early
return to normal activities was seen in Stoppas and TEP compared to Lichtenstein. One recurrence was seen in TEP and Lichtenstein. Post
operative pain was least with TEP than the other two groups. Open surgery proved to be more cost effective than TEP. TEP in CONCLUSION:
comparison with Stoppas and Lichtenstein is safer with lesser complications and earlier recovery, but less cost effective than open surgery. In
developing countries, where cost effectiveness plays a crucial role in deciding the surgery, Stoppas is safe with minimal complications and rapid
recovery. This study also demonstrates the effect of surgeon's experience on clinical outcome, with learning curve being shorter in open vs TEP
repair

Published: March 2023

BACKGROUND: Oesophageal varices have high mortality (40-70%) and occur 5-15% of cirrhotics per year.
Cirrhotics need to be screened for Oesophageal varices with endoscopy once in 2-3years. Non-invasive predictors of
varices-Fibroscan,Fibrotest,Platelet count/Splenic diameter(PC/SD) ratio reduce the burden and risk of endoscopy and make it preferrable in
selected patients. Of these PC/SD ratio is promising. MATERIALS AND METHODS:50 patients diagnosed as cirrhosis are selected satisfying
inclusion and exclusion criteria. All underwent Ultrasonography of abdomen, Upper Gastrointestinal endoscopy to conrm cirrhosis and
Oesophageal varices and were divided in to two groups A&B based on with and without varices respectively. PC, splenic length(SL) and PC/SD
ratio were compared between the two groups.

Published: March 2023

Background: PPH is responsible for 25% of all maternal deaths. In India, PPH incidence in India is 2%-4% following
vaginal delivery and 6% following cesarean section. PPH as the important cause of 19.9% of maternal mortality in India.
Objectives:The objectives of the study were to study the incidence, risk factors, cause,complications and management of PPH. Materials and
Methods: This prospective observational study was conducted in the Department of OBGY, SVPIMSR,Ahmedabad, India. A total number of 50
cases of postpartum hemorrhage that fullled the selection criteria were included. The records were analyzed with respect to maternal Results:
age, parity & etiological prole and maternal consequences in cases of PPH at our tertiary care center. Main cause of PPH in this study was uterine
atony i.e. 56.38%. Second common cause was traumatic i.e. 21.27%. 20% of cases were given blood transfusions. However,maternal death due to
hemorrhage in our study was negligible. Conclusions: Active management of the third stage of labor is crucial.Availability of blood and blood
products is very crucial. Prediction and assessment of blood loss and timely identication of uterine atony are remaining the cornerstone for
prompt and effective management of PPH. 60% cases were managed by medical methods while the rest of the cases required surgical
management. Among the medical management uterotonic drugs and bimanual uterine compression was used while among the surgical methods
repair of cervical and vaginal laceration was mostly required.

 This study presents a novel method to assess the learning effectiveness using Electroencephalography (EEG)-based Multi-Time Scale Spatiotemporal Compound Model (MTSC). Due to the evaluation of navigation learning, which is centered on the practice innovation ability devel?opment, it is difficult to assess the learning effectiveness in cultivating students’ ability objectively by questionnaire or other assessment methods. Research in the field of brain science has shown that innovation ability can be reflected from cognitive ability which can be embodied by EEG signal features. Therefore, a navigation learning assessment method was applied to detect the cognitive training traces by EEG-based MTSC. To verify the validity of the method, three navigation missions with increasing cog?nitive difficulty were designed, and 41 participants attended the experiment. The features of participants’ EEG signals were extracted and classified by MTSC. Comparing the results between experimental group and control group, it can be seen that MTSC can effectively distinguish the cog?nitive training traces of students in the navigation problem?solving process. In addition, MTSC achieved 89.2% accu?racy and 0.883 F1-Score on features classification, which had an average improvement of 15.7% over other three tra?ditional EEG classification models in accuracy. The results indicate that the navigation learning assessment method provides a useful evaluation approach for learning effec?tiveness using EEG-based MTSC.

Разработанная ранее авторами технологическая схема получения угле-титанового композита, основанная на пропитке углеволокна жидкофазной промежуточной матрицей с пониженной относительно титана температурой плавления, применена в настоящей работе для получения композитов с основной матрицей титанового сплава ВТ16 (Ti-Al-V-Mo) взамен технически чистого титана в первых экспериментах. Технологический режим получения композитных образцов при этом изменён: повышено давление, понижена температура и уменьшено время пропитки. Всё это вкупе с применением титанового сплава взамен технически чистого титана привело к существенному повышению прочности композита.
