Authors: Yasin Asma , Afzal Madiha , Aziz Uzma
Published: December 2021

Background: Abnormal uterine bleeding is defined as irregularities in the menstrual cycle involving frequency, regularity, duration, and volume of flow outside of pregnancy. Up to 1/3rd of women experience abnormal uterine bleeding in their life, with irregularities most commonly occurs at menarche and perimenopause due to disruption of the hypothalamic-pituitary-ovarian axis. Aim: To compare the effectiveness of Norethisterone and Dydrogesterone for the treatment of irregular menstrual cycles due to abnormal uterine bleeding of ovulatory or endometrial dysfunction and to check for patient satisfaction after the use of prescribed hormones by taking their feedback. Methods: This observational, comparative, cohort-prospective study was conducted on 100 nonpregnant women between the ages of 15-45 years who presented with complaints of irregular menstruation in gynae outdoor of AMTH for 6 months from April 2021 to September 2021. After excluding pelvic pathology, known thyroid disease, coagulation disorder, or use of the contraceptive method, the participants were divided into Group A and Group B, each having 50 participants. Results: The mean age±SD of the participants in Group A was 29±3.4 while Group B had mean age±SD was 29.5±3.6. In Group A, 38(76%) patients reported a regular menstrual cycle after 3 months of use while 12(24%) patients complained of persistent irregular menstrual cycle despite 3 months use of Norethisterone with compliance in Group B using Dydrogesterone, 22(44%) patients had regular menstrual cycles while 28(56%) patients had persistent irregular menstrual cycles after three months of use. Conclusion: So we concluded from our study that Norethisterone had a better cycle control than Dydrogesterone.

Published: December 2021

Background: Parkinson’s Diseases (PD) cause some non-motor issues that could lead to disability. One of such determinal non-motor symptoms is orthostatic hypotension (OH) which is still understudied in our local setting despite of its high prevalence worldwide among patients of PD. Aim: To determine frequency of orthostatic hypotension in Parkinson’s disease Methods: This Cross-sectional study was conducted at Department of Neurology, Mayo Hospital, Lahore for 6 months after the approval of synopsis [April 9, 2018 till Oct 9, 2018]. A sample of 95 cases was selected using non probability consecutive sampling from 95 patients of Parkinson’s Disease aged 25 years and more. After taking consent from patient and recording sociodemographic information, a lying-to-standing orthostatic test was performed to evaluate the orthostatic hypotension and SBP and DBP was recorded. All data was collected using a self structured proforma and analyzed using SPSS v 21. Results: The mean age of cases was 47.46 ± 8.97 years with male to female ratio of 1.97:1. The mean systolic and diastolic blood pressure was 120.60 ± 11.80 and 86.20 ± 8.68 respectively. The frequency of orthostatic hypotension was seen in 51(53.7%) while other 44(46.3%) cases did not have orthostatic hypotension. Conclusion: Through the findings of this study we conclude that frequency of orthostatic hypotension in Parkinson’s disease is very much high i.e. 53.7% with highest frequency in cases with longer duration of disease.

Comparison of Diagnostic Accuracy of Magnetic Resonance Spectroscopy with Conventional Magnetic Resonance Imaging for Brain Tumors and Correlation with Histopathology as Gold Standard
Authors: Sarfraz Saulat , Farzana Mahwish
Published: December 2021

Background: In spite of recent advances in the use of diagnostic imaging modalities none of them has a hundred percent accuracy. So, misdiagnosis still occurs. Many trials are being done to evaluate the accuracy of these tools individually or in combination. The most useful investigation is MRI which broadly gives information of lesion as well its relationship with surrounding structures. While magnetic resonance spectroscopy further characterizes the lesion into benign or malignant. So this study is bit superior giving more details. By enlarge histopathology is gold standard for ultimate diagnosis. However these radiological investigations are extremely important for preoperative planning as well management of the lesion. In this study we compare the diagnostic accuracy of Magnetic Resonance Spectroscopy (MRS) with conventional MRI (Magnetic Resonance Imaging) sequences for diagnosis of brain tumors keeping histopathology as gold standard. Methods: The study was performed in 150 clinically suspected cases which were referred to Radiology Department from OPD, Indoor, Emergency and private sources from outside the hospital. Results: Majority 85(56.7%) were adult males and 65(43.3%) were adult females. The study was divided into two major age groups. There were 33cases (22%) with average age 20-35 years. The other age group 36-50 years had 40(26.7%) Majority of the cases 77(51.3%) were of average >50 years of age. The higher age groups showed a female dominance. Histopathology of 100(66.7%) cases confirmed positive and 50(33.3%) negative for MR Spectroscopy. On comparison of conventional MRI with contrast, and Histopathology it was observed that the sensitivity of MRI was 74.0% and the specificity 82.0%.The positive and negative predictive values gave a lower accuracy rate of 76.6%. Conclusion: The conclusion of our study is that MRS is a rigorous, non-invasive, safe and convenient imaging modality for the evaluation of brain tumors as compared to MRI.

Published: December 2021

El cambio climático afecta de forma negativa a los ecosistemas, medios de vida, y a la sociedad en general. Debido a esto, surgen alternativas como la bioeconomía que busca disminuir el impacto ambiental y cambio climático a través de sus principales senderos. De esta forma, el objetivo de la presente investigación fue evaluar la contribución del sector agrícola al Producto Interno Bruto (PIB) de Honduras y el potencial de desarrollo de la bioeconomía en el país. La investigación se llevó a cabo en Honduras, durante el año 2020 y el enfoque utilizado fue cualitativo; concretamente, la técnica utilizada fue una revisión de literatura sistemática. Los principales resultados muestran que durante el período entre los años 2015 y 2018 la contribución del sector agrícola se mantuvo en 14%, ocupando el tercer lugar después del sector de industria manufacturera y la intermediación financiera. Ahora bien, en relación a la bioeconomía fue posible establecer contribuciones puntuales en los siguientes senderos: a) Valoración de los recursos de la biodiversidad, b) Eco intensificación, c) Aplicaciones de biotecnología, d) Servicios eco sistémicos, e) Eficiencia de las cadenas de valor, y f) Biorefinería y bioproductos. Como conclusión se tiene que el tema de bioeconomía en Honduras se inclina hacia la biotecnología y la biorefinería. Aunque ambos senderos involucran tecnologías poco accesibles a pequeños productores agropecuarios. Por lo tanto, es primordial el diseño participativo de políticas y estrategias de bioeconomía para el sector de productos y servicios, lo que mejoraría la competitividad y desarrollo sostenible del país.
Ethical Issues at the Beginning of Life
Authors: Song In Gyu
Published: December 2021

With improvements in the survival rate of high-risk newborns, the need for ethical considerations is increasing. In the event of a conflict of opinion between the parents and the medical staff about the treatment decision, often there are concerns about who needs to make the decision that would be in the best interest of the baby. In this article, focusing on the guidelines for neonatal resuscitation revised in 2020, ethical issues that may arise before and soon after birth are reviewed. In addition, the considerations in determining the treatment direction for neonates with poor prognosis and the care required for babies and their families during the neonatal period have been investigated. Decisions about withholding or discontinuing neonatal resuscitation are often time-pressed since they are often made when labor is imminent or are needed shortly after the baby’s birth. The recommendations put forth by the American Heart Association in 2020 may be referred toward decision making. Since the medical condition of high-risk newborns also often change rapidly following admission, it becomes necessary to review the treatment goals periodically. Though principles suggested by the American Academy of Pediatrics regarding the treatment decision of high-risk newborns are available, in Korea, it is also essential to consider the country’s law while discussing life-sustaining treatment. Improving the patient's quality of life is equally important as deciding treatment plans and approaches for sustaining life. Toward this, it becomes necessary that the medical staff treating high-risk newborns be educated on palliative care and build a support system.

Published: December 2021

En este trabajo se presentan los resultados del estudio bioarqueológico efectuado sobre el enterramiento humano reportado en el yacimiento El Quimbayo, situado en el municipio de San Jerónimo, Antioquia (Colombia). El sitio está contextualizado por datación relativa, dentro del marco histórico del periodo Alfarero Medio (siglos II a. C.- IX d. C.). Los restos óseos se hallaron acompañados de material cerámico del estilo Ferreira y Marrón Inciso, además de abundante carbón y evidencias de combustión en el suelo. A partir del análisis bioarqueológico se infiere que se trata de un entierro primario, durante el cual se llevó a cabo un “doble ritual” de cremación e inhumación.Los elementos óseos encontrados son en su totalidad humanos, pertenecen a un individuo infantil y manifiestan huellas de exposición térmica en hueso “fresco”, lo que indica temperaturas altas superiores a los 700 °C. Los resultados obtenidos contribuyen con nuevos datos al conocimiento de las prácticas funerarias de los antiguos pobladores de la región, concretamente sobre el papel del fuego en los rituales funerarios.

Published: December 2021

El artículo tiene como objetivo analizar el modelo Medellín y su influencia en la configuración de las lógicas de tratamiento de los problemas de seguridad en la ciudad entre los años 2008 y 2015. Metodológicamente, el texto realiza una interpretación del problema, así como de la variada información cualitativa y cuantitativa recolectada, producto de un ejercicio de revisión documental enfocado principalmente, en documentos oficiales, investigaciones académicas y algunas entrevistas. Aunque existen diversas posiciones sobre lo que se ha dado en llamar el “modelo Medellín” para la gestión de la seguridad, en general, es posible postular que dicha estrategia, centrada en el urbanismo social y la prevención situacional del delito se constituyó en una intervención innovadora de carácter preventivo para mejorar la seguridad en espacios públicos y en algunas zonas de la ciudad reduciendo, en parte, la histórica deuda social para importantes territorios de la ciudad.
A Research on Routing and Spectrum Allocation Algorithm for Elastic Optical Networks Based on Deep Learning
Authors: Cheng Lina
Published: December 2021

Dynamic allocation request and spectrum release will lead to spectrum fragmentation, which will affect the allocation of subsequent services and spectrum resource utilization of elastic optical network. This paper proposes a new routing and spectrum allocation algorithm based on deep learning, which will find the best routing and spectrum allocation method for a specific network, so as to improve the overall network performance. Simulation results show that compared with the traditional resource allocation strategy, the neural network model used in this paper can improve the degree of spectrum fragmentation and reduce the network blocking probability.

Continuidad del modelo del buen gobernante religioso según Gonzalo de Berceo en una biografía novohispana del siglo XVIII
Authors:   El Colegio de Morelos, Morales Prado Wendy Lucía
Published: December 2021

A pesar de que en las múltiples fuentes de la cultura católica y en la Biblia abundan imágenes del líder religioso, con el paso de los siglos, a menudo se vieron las dificultades que surgían al intentar conciliar el ejercicio del poder terrenal y las necesidades impuestas por la ideología religiosa. Incluso en el caso de los integrantes del alto clero, como obispos y arzobispos, se buscaban referentes y modelos de buen gobernante que se encontraron, en un primer momento, en las figuras de los padres de la Iglesia, como san Agustín, y los sumos sacerdotes del Antiguo Testamento, como Moisés y Aarón. Sin embargo, la figura del buen gobernante se allegó de diversos elementos y otras vidas de personajes bíblicos. Como prueba de ello, a lo largo de estas páginas, se detallará el caso de un libro que en el siglo XVII mostró la complicada articulación del ideal del gobernante con un trasfondo religioso, posteriormente, se repasa cómo se concebía un líder religioso y algunos factores que influyeron en su configuración: el modelo primigenio del mártir, el modelo de los padres de la Iglesia, y finalmente, los modelos de Gonzalo de Berceo, que muestran su vigencia a lo largo de los siglos cuando se analizan junto con la biografía y los seis sermones dedicados a los funerales de Manuel Fernández de Santacruz, obispo poblano de 1677 a 1699.

Published: December 2021

On the basis of past 115 years (1901-2015) rainfall data of five districts of south Gujarat, the Mann-Kendall trend, Sen’s slope and regression slope showed that annual and monsoon rainfall at Valsad, Dang and Surat shows the increasing trend while, that of Navsari and Bharuch districts are declining. The monsoon season (summer monsoon) rainfall variability of Valsad, Dang, Surat, Navsari and Bharuch districts was recorded is 30.1%, 30.9%, 35.9%. 33.3% and 38.6%. The high coefficient of variation (CV) denoted that the variability of rainfall is not equally distributed and the amount of rainfall is lowest. The Bharuch district the annual and monsoon CV per cent denoted that the variability of rainfall in both seasons are very high. Valsad was recorded lowest CV with highest rainfall while the data are represent that variability of rainfall which can varies Bharuch to Dang in different districts of south Gujarat. The data shows that Dang district comes under high rainfall and Bharuch under low rainfall on south Gujarat. A low standard deviation indicates that the data points tend to be close to the mean of the set, while a high standard deviation indicates that the data points are spread out over a wider range of values. Similarly high SD is reported at Dang district because of high range of rainfall and lowest SD is found at Bharuch district because of low rainfall variability. The rainfall distribution different season viz., pre monsoon, monsoon post monsoon and winter season, the highest present contribution of rainfall is observed during monsoon season followed by post monsoon in all the five districts of south Gujarat. Rainfall contribution during remaining months was less than one per cent. While month wise analysis shows during monsoon season highest rainfall per cent contribution to annual rainfall is in July followed by August and June months at all the five districts of south Gujarat.

Published: December 2021

Annual and seasonal variability and trends in low cloud cover over India were analyzed for the period 1961-2010. Taking all period into account, there is a general decrease in mean low cloud cover over most regions of India, but an increase in the Indo-Gangetic plains and northeast India. Long term mean low cloud cover over India has inter-annual variations with highest cloud cover (39.4%) in monsoon and lowest cloud cover (10.5%) in winter season. The annual mean low cloud cover shows significant decreasing trend of -0.45% per decade, mainly contributed by monsoon where declining rate is -1.22% per decade. Out of the total numbers of stations showing decreasing trends, 65%, 47%, 53%, 71% and 37% of the stations show significant decrease in low cloud cover for annual, winter, summer, monsoon and post monsoon respectively, with large trend magnitudes occurring in central India. Spatially, the seasonal patterns of trends in low cloud cover confirm the annual patterns in most cases. Data analyses show that low cloud cover is having a strong negative correlation with maximum temperature and diurnal temperature range and a strong positive correlation with numbers of rainy days during the period of study.
Observation and simulation of mountain wave trains in a tropical cyclone situation
Authors: Lei LI , CHAN P.W. , TSE S. M.
Published: December 2021

This paper documents the observations by radar of wave trains downstream of mountains in a tropical cyclone situation.  The wind disturbances associated with the wave trains together with the background strong southeasterly flow result in the occurrence of low-level wind shear as detected by the radar. So the case is not just scientifically interesting, but it also has practical application value.  The wave trains can be simulated by using a computational fluid dynamics model initialized homogeneously by the upper air ascent data at the time close to that the occurrence of the wave trains.  This points to the potential of using such a model in simple setup to forecast the occurrence of low-level wind shear.

Authors: JAYAKUMAR M. , RAJAVEL M.
Published: December 2021

Climate plays important role in production of coffee. Adequate quantum and timely receipt of blossom rainfall for flowering and subsequent backing showers influence the berry set and yield of coffee. Harvesting of Arabica coffee in Kerala State with humid tropical climate in India is done by December-January and harvesting of Robusta coffee is taken up during January-February. In this paper, attempt was made to develop agrometeorological models to forecast the yield of these two varieties coffee by utilising monthly climate variables from January to December. Long term data from 1991-92 to 2012-13 on coffee yield and weather data from 1991-2012 recorded at Regional Coffee Research Station, Chundale located in Wayanad district of Kerala State was used to develop agrometeorological model. Statistical regression model between climate indices and yield of Arabica and Robusta coffee was developed and the model was validated using crop and climate data for 2013 and 2014. The model demonstrated that climate indices based agrometeological model is able to forecast the yield of coffee in Kerala.

Authors: Silva Taiane Vanessa da
Published: December 2021

Busca-se com este artigo indicar os limites e possibilidades da exposição de longa duração do Museu Histórico de Londrina-PR (MHL) em relação às representações da história da cidade. A pesquisa tem como norte a análise textual qualitativa (MORAES, 2003) e o conceito de representação (CHARTIER, 1990). Selecionou-se como fonte histórica o memorial descritivo da exposição, a fim de compreender as intenções da sua produção, entre 1996 e 2000, e a narrativa construída no Museu Histórico. O documento selecionado indica o diálogo da exposição com a história “oficial” de Londrina, a qual destaca mitos fundadores e aspectos positivos da cidade em detrimento de memórias e identidades plurais. Porém, a partir de 2016, a exposição “permanente” do MHL passou a contar com intervenções e inclusões das memórias de povos indígenas, a fim de superar lacunas. Além disso, a pesquisa também aponta outras possibilidades de representações por meio de ações educativas.

Elementos da natureza, artefatos históricos, objetos folclóricos: sentidos e representações atribuídas à coleção etnológica do Museu Júlio de Castilhos (1901-1958)
Authors: Melo Roberta Madeira de , Possamai Zita Rosane
Published: December 2021

Neste artigo analisamos como se formou a coleção etnológica do Museu Júlio de Castilhos e quais foram as representações e sentidos sobre os povos indígenas produzidos pelo museu no período de 1901-1958. Com esse intuito, investigamos as quatro primeiras direções do museu, destacando as semelhanças e as singularidades dessas administrações nos processos de musealização dos objetos indígenas. Demonstramos que, no período analisado, os objetos indígenas foram considerados como objetos científicos, vinculados aos estudos de História Natural como artefatos históricos e como objetos que representavam culturas folclóricas. Compreendemos assim, que a história das coleções e da musealização dos objetos indígenas contribui para a compreensão de como se produziram imaginários acerca dos povos originários em espaços museais e, ainda, colabora para a problematização crítica da relação dos museus com as nações indígenas.

Electron cyclotron resonance plasma heating (ECRH) system has been recently installed on the gas dynamic trap (GDT) magnetic mirror. Two microwave beams are injected into the plasma at an angle of 36° with respect to the machine axis in a form of extraordinary (X) waves which are subsequently absorbed in the first harmonic cyclotron resonance. Each microwave beam is generated by a Buran-A type 450 kW/54.5 GHz gyrotron. The article reports on the first microwave injection experiments with limited total power of 300 kW. Adjustment of experimental conditions and magnetic field reconfiguration resulted in an increased diamagnetic signal, electron temperature and other plasma parameters
Investigation of the Dynamics of Nucleate Boiling in Subcooled Falling Liquid Films
Authors: Serdyukov Vladimir , Surtaev Anton , Volodin Oleg
Published: December 2021

This paper deals with the features of nucleation dynamics at boiling in falling water films at different subcooling, Reynolds number and heat fluxes. With the use of high-speed infrared and digital video the local parameters of nucleate boiling in falling liquid films such as: bubbles’ diameter before condensation, frequency of nucleation and temperature of onset of bubble appearance were received. Analysis of the experimental data showed that bubbles’ diameter before condensation has strong dependence on initial temperature and increases with the rise of heat flux. The main influence on nucleation frequency has the variation of heat flux density. At the same time the experimental data on nucleation frequency in falling water films are close to the frequency of nucleation at pool boiling. To identify the main features the comparison of received data on the local characteristics at boiling in subcooled falling liquid film with existing models for pool boiling was made

Experimental study of subsonic round micro jets in the diffusion combustion of propane and without combustion at low Reynolds numbers was performed. Development of the jet was as under natural conditions without the acoustic excitation and as acoustic excitation of high intensity (90– 100 dB), frequency of acoustic oscillations was from a few Hz to 6 kHz. The jet flow was realized through the nozzle of round cross-section with a bevel of 45° and a diameter d = 0,45 mm. Blown trough the nozzle mixture of propane-butane previously passed through the evaporator, then through flowmeter (two-channel PR4000B) gas consumption. The studies were performed using Schlieren method based on the IAB-451. The pictures of the shadow visualizations was received, the presence of a developing hydrodynamic instability was found, including the presence of convective forces (by burning). The pictures of diffusion combustion of round propane-butane micro-jet at various modes of combustion – lifted and attached flame were received. It was found that the flame in the diffusion combustion of round microjet at an external acoustic field, exposed to flattening and bifurcation as the air free round microjet, while the source of acoustic oscillations is oriented perpendicular to the jet. The pictures of the diffusion combustion for splitting impact jet by acoustic field were obtained. It was found that in this case on the limits plate two temperature maximum were realized.

Published: December 2021

This article focuses on the policy of the US to control Middle East oil and to strengthen its political position. The US believes that the Middle East is an important region and the situation here can directly threaten America's interests and economic security. After the "democratic" experiment carried out, in recent decades, the Eastern Region has become a place in the ruins, with dozens or perhaps hundreds of extremist and terrorist groups. In other words, the result is exactly the opposite. Conspiracy theorists say that secret powers, such as giant banks and transnational companies have created conditions for the fragmentation of the region; The weakening of the nation states has prevented the spread of global capital and that entry of this capital into the markets of the Middle East has been interrupted.

Authors:   Western Caspian University, Karamova Natavan
Published: December 2021

The attempt has been made here to study the influence of examination stress psychophysiological changes which take place in children aged 14-16 years. Children’s psychological cognitive indexes were studied. The experiments were conducted on the children in three stages: in one of the usual school hours (control), and before and after the examination. The data analysis indicates that psychophysiological changes were more prominent at the high level of anxiety index, predominance of sympathetic tone, and weakness of cognitive indexes. After the examination all the above indexes were restored to their control level. The comparative analyses of the obtained data allowed us to put forward a proposal that examination stress causes psychoemotional conditions in children. Depending on their mental development, it can exert serious influence on their health.
