Authors: Marín Manuel
Published: January 2023

El principal hábitat del Canastero (Pseudasthenes humicola) son matorrales de zonas áridas a semiáridas con arbustos espinosos o cactáceas. La época de postura transcurre desde finales de agosto a principios de diciembre. Su nido es bastante visible de un tamaño que varía entre 27-76 cm de largo y en promedio está colocado a 1,8 m (n=58) es construido con palitos con espinas, nidificando preferencialmente en Espino (Vachellia caven) (55,2%) o Trevos (Trevoa trinervis)(36,2%), (n=58). Sus huevos eran blancos con muy poco lustre su forma mayoritariamente eran subelíptica (34,7%) subelíptica corta (22,1%), y ovales (20%). La nidada varió entre 3 y 4 huevos, pero fue mayoritariamente (56,4%) de 3 huevos (n=62). Ambos adultos incuban, y el periodo de incubación fue de 20,7 días, el rango = 20-22 días (n=10) es muy prolongado para un passeriforme pequeño. Los pichones al eclosionar son típicamente altriciales y salen del nido a los 14-16 días, mayoritariamente 15 días. Se observó que el principal alimento a los pichones fueron larvas de Lepidoptera: Geometridae. De 82 huevos, 39 polluelos (47,5%) salieron exitosamente del nido, resultado que está en el rango para pichones altriciales con nidos cubiertos. Llama la atención que 7 de 53 polluelos (13,2%) de diferentes nidos y ya crecidos se encontraron muertos dentro del nido con grandes hematomas en la cabeza y en el cuerpo al parecer un tipo de infanticidio pasivo y directo.

Face Generation Using General Adversial Networks
Authors: Reddy Chandana , Ashritha Rishitha
Published: January 2023

Face generation is a difficult task with numerous uses in security (for example, creating portraits from descriptions), styling, and entertainment. In this study, we investigate generating faces conditioned on identification using modifications to generative adversarial networks (GANs). In the realm of artificial intelligence, deep learning has had significant success, and several deep learning models have been created. One of the deep learning models, Generative Adversarial Networks (GAN), which was proposed based on zero-sum game theory and has become a new research hotspot. The importance of the GAN model variation is to provide more accurate and realistic data by using unsupervised learning to obtain the data distribution. Due to their vast potential for use in areas including language processing, video processing, and image and vision computing, GANs are currently the subject of extensive research. This project introduces the history of the GAN, theoretical models, and extensional variants of GANs, where the variants can either modify the fundamental structures of the original GAN or further optimise it. The typical uses of GANs are then described. Finally, a summary of the current GAN issues and a description of the models' upcoming work are provided.

One of the locations for harvesting water spinach in West Java is from the Putra Tani Farmers Group in Kemang Village, Bogor Regency, which was established in 2009. The Putra Tani Farmers Group produces water spinach and markets it in Bogor Regency and Bogor City. Marketing of water spinach by farmer groups is considered not optimal, so it is necessary to formulate an appropriate marketing strategy by analysing internal factors (strengths and weaknesses) and external factors (opportunities and threats) of water spinach marketing. This type of research is a qualitative descriptive study with 25 respondents who are members of the Putra Tani Farmers' Group using non-probability sampling. The analytical method adopts SWOT. From this, several alternative marketing strategies for water spinach were obtained, namely maintaining the quality of water spinach first so that the price is higher than water spinach, which is applied with chemical fertilizers and pesticides. Second, participating in exhibitions or establishing independent markets to expand product promotion. The third is to improve the packaging quality and reduce water spinach damage, thereby increasing the price. Fourth, expanding sales to various restaurants. Fifth, increase product promotion through the market (online market) to meet consumer needs for a healthy lifestyle.

Oral and Otolaryngological Complications of Radiotherapy for Head and Neck Cancers among Patients attending Ocean Road Cancer Institute, Tanzania
Authors: Abraham Z S , Ngunyale B , Massawe E R , Ntunaguzi D , Mpondo B
Published: January 2023

Background: The prevalence of head and neck cancers is on the increase worldwide. Treatment modalities include surgery, radiotherapy and chemotherapy. Radiotherapy with or without chemotherapy affects different parts of the body upon their exposure including the ear, nose, throat and the oral cavity. Data on these complications is scarce. The aim of this study was to determine the proportion of acute oral and otolaryngological complications of radiotherapy with or without chemotherapy for head and neck cancers.

Methods: A retrospective cross-sectional, hospital based study was done to 80 patients with head and neck cancers who have just completed radiotherapy with or without chemotherapy at Ocean Road Cancer Institute (ORCI). Data was collected using a structured questionnaire within one week after completion of radiotherapy. Patients who reported hearing loss underwent otoscopy and audiological assessment including tympanometry and pure tone audiometry. Data was analyzed using SPSS program.

Results: The proportion of males was higher than that of females in the ratio of 2:1 and majority of the patients involved were in the 6 decade of life, 

(27.5%). Out of the 80 study participants, 80% were found to have oropharyngeal mucositis, 90% were found to have xerostomia and 50% were found to have dysphagia. In addition, 76.2% of patients reported to have developed taste disorders after radiotherapy and 43.1% reported to have developed voice disorders. The proportion of hearing loss following radiotherapy was 21.9% though this should be taken with caution since there was no before and after intervention taken.

Patients with sinonasal cancers had the least proportion of oral and oropharyngeal mucositis (50%), xerostomia (64.3%) and voice disorders (14.3%). Most of patients who developed hearing loss had nasopharyngeal cancer (85.6%) and salivary gland cancer (66.7%) while patients with oropharyngeal cancer, hypopharyngeal cancer and laryngeal cancer did not develop hearing loss at all.

Conclusion: Oral and otolaryngological complications of radiotherapy with or without chemotherapy for head and neck cancers at ORCI are quite prevalent. Prevention of complications should be highly regarded especially by using shield protectors on uninvolved areas and advanced radiotherapy machines should be considered to minimize such complications.
A Comparative Study of Diclofenac and Wound Infiltration to Additional Ilioinguinal/iliohypogastric Nerve Block With 0.25% Plain Bupivacaine for Pain Relief in Children Undergoing Groin Surgery – University Teaching Hospital (UTH), Lusaka
Authors: Kabwe Jane , Chisakuta A M , Ismailova F
Published: January 2023

ABSTRACT

Objective: Surgery in the groin region is commonly performed in paediatric patients at the University Teaching Hospital (UTH). Intramuscular (IM) Diclofenac and wound infiltration, with lignocaine, are the commonest analgesics administered intra- operatively. This study aimed at determining whether an additional ilioinguinal/iliohypogastric nerve block with 0.25% plain bupivacaine, done using the landmark technique,would improve post- operative analgesia in children undergoing groin surgery at the UTH when compared to IM diclofenac and wound infiltration with 1% lidocaine (with adrenaline 1:200,000).

Methods: A non-randomized intervention study of

36 children undergoing unilateral inguinal herniotomy, hydrocelectomy and orchidopexy was conducted at UTH. The children were allocated to two groups – Group 1 (control) received IM diclofenac and wound infiltration (UTH usual care), while Group 2 (intervention group) received 

medication as in control plus an ilioinguinal/ iliohypogastric nerve block performed by landmark technique.

The Mann-Whitney U test was used to compare the pain scores between the two groups and any result yielding a p-value of less than 5 percent was statistically significant.

Results: The operations done were unilateral inguinal herniotomy, hydrocelectomy and orchidopexy. Half of the participants were between 2-5years old and the other half between 5-7years. Post-operatively, the pain scores measured at times 0 and 1 hour were statistically non-significant in both groups (p-values 0.181 and 0.355 respectively). At the 6th hour post-operative, all of the participants had pain scores of 0. Oral Paracetamol (15 - 20 mg/kg) was the only post-operative analgesic received by the patients in the study.

Conclusion: This study showed that the addition of ilioinguinal/iliohypogastric nerve block, done with the landmark technique, does not offer superior pain relief during the post-operative period in children undergoing unilateral groin surgery at UTH.
TNF-alpha Levels in Serum and Mononuclear Cell Lysate of Nigerian Tuberculosis Patients at Diagnosis
Authors: G Arinola O , Edem V F , Arinola O G
Published: January 2023

Background and Objectives: The need for additional markers for differential diagnosis of drug resistant Mycobacterium tuberculosis (M.tb) and drug sensitive M.tb have been raised by previous studies. Tumor necrosis factor-alpha (TNF-á) produced by monocyte/macrophage, neutrophilic and lymphocytic linkage plays a central role in effective immunity to many disease conditions including M.tb. Since M.tb either preferential inhabits or transits cells producing TNF-á, it is therefore diagnostically useful to measure the levels of TNF-á in the both mononuclear cell lysate and serum of drug sensitive TB (DS-TB) patients and multi-drug resistant TB (MDR-TB) patients compared with healthy controls.

Materials and Methods: The study was conducted in the Department of Chemical Pathology and Immunology, University of Ibadan, Nigeria; Medical Out-Patients' Department and Multi-Drug Resistant Tuberculosis Center, University College Hospital, Ibadan, Nigeria. TB patients were selected by Consultant Chest physician after detailed laboratory and clinical procedures. The levels of mononuclear cell lysate- and serum- TNF-á were measured using enzyme linked immunosorbent assay (ELISA).

Results: Serum and lysate TNF-á levels were significantly elevated in DS-TB patients (p <0.05) and MDR-TB patients (p < 0.05) compared with the control. But serum and lysate TNF-á levels were not significantly different in DS-TB patients compared with MDR-TB patients (p > 0.05).

Conclusions: Serum level of TNF-á or lysate TNF-á does not differentiate DS-TB patients from MDR- TB patients and the use of antagonist of TNF-á be handled with caution in TB patients.

Published: January 2023

Objectives: To investigate the clinical presentation of patients with extradural spinal tumours and establish the factors that determined the treatment they received and outline the outcomes of that treatment at the University Teaching Hospital between January 2013 and December 2016.

Material and Methods: This was a retrospective study of the presentation, management and short- term outcome of extradural spinal tumours at the University Teaching Hospital. A questionnaire was used to obtain data from patients' hospital records. Data was analysed using Microsoft Excel and the Statistical Package for Social Sciences version 25 software.

Results: Of the 62 patients in the study,34 were female and 28 male. The age range was 14 to 87 years, with a mean of 55.03. Backache (93.8%), Limb weakness (91.9%), loss of sensation (50%), urine and stool incontinence (43.5% and 41.9% respectively), back deformity (11.3%), night pain (85.5%), weight loss(67.7%), poor appetite (61.3%), fever (35.5%) and night sweats(29%) were common symptoms. Sixty-eight percent of patients were bedridden. Visual Analogue Scale scores were greater than 5 in 84% of patients. A muscle power grade of 3 or less (n=48), impaired muscle tone (n=38), abnormal reflexes (n=52), presence of a sensory level(n=37) and back deformity (n=17) were common signs. Plain radiography, Computed Tomography Scans, Magnetic Resonance Scans and Tecnetium Bone scans were done in 60, 35, 17 and 2 patients respectively. The commonest surgical host category was A (64%). Secondary Extradural Spinal Tumours comprised 82% while 18% were primary. Surgery was done in 14 patients with 1 failing to afford implants. Forty-eight received nonsurgical treatment. Nineteen percent of patients had improved pain scores but the rest remained the same or worsened after treatment. Complications included decubitus ulcers, Urinary Tract Infection, Deep Veinous Thrombosis, pneumonia, sepsis and joint stiffness. Fourty patients died and eighteen patients were lost to follow-up.

Conclusions: The ages of patients followed normal distribution with female to male ratio of 1.2 to 1. Most patients presented with symptoms and signs of advanced disease. The type of extradural spinal tumour, stage of disease, completeness of diagnostic workup, availability of implants, need for tissue diagnosis, type of surgical host and availability of nonsurgical treatment modality determined the choice of treatment. Poor outcomes in quantity and quality of life are a reflection of the late presentation, delayed diagnosis, lack of resources and difficulty of treating these tumours. Extradural spinal tumours are not uncommon and cause significant morbidity and mortality in those affected.

Authors: Jacobsen Prof. Kathryn H , Sinkala D , Fleming L C , Silwimba F
Published: January 2023

Background: Young children with sickle cell anaemia (SCA) require frequent medical interventions to prevent fatal complications and improve quality of life.

Methods: The care givers of 40 randomly-sampled

children <5 years old with SCA who lived in rural Chilubi district in northern Zambia were interviewed in 2016.

Results: Most of the parents had poor knowledge of SCA, treated most SCA symptoms at home, and were unaware of the SCA complications requiring emergency clinical care. Distance and cost were frequent barriers to accessing medical services. The local clinic was perceived to lack the human and material resources necessary to offer high-quality care.

Conclusions: Community-based family health education programs may increase parental knowledge of SCA and reduce some of the barriers to seeking care for their children. Additional SCA training for nurses and clinical officers will enable them to provider higher-quality preventive and therapeutic care.

Authors: Mulenga M , Bvulani B , Munkonge L
Published: January 2023

Background: This study was conducted to determine our own institutional rate and risk of inguinal hernia incarceration among infants and children awaiting elective surgery. Inguinal hernias in infants and children are very common. One of their common complications before surgery is incarceration. Rate and risk of incarceration among our patients awaiting surgical care was not known.

Method: A retrospective review of infants and children under the age of 17 years, who had undergone inguinal hernia repair or had incarcerated, from January 2015 to January 2017 was performed. Interviewer completed questionnaires were used to abstract data from the clinical records. Atotal of 364 patients were included for analysis, in this study. Descriptive statistics, Regression Analysis and Kaplan Meiers Survival Analysis were employed.

Results: The infants and children were stratified into seven age groups. The overall incarceration rate was 13.45%. The risk of incarceration was age dependent. It ranged from 0.52 daily risk of incarceration, among neonates, to zero daily risk of incarceration among older children. Longer wait times were associated with increased rate and risk of inguinal hernia incarceration.

Conclusion: The overall rate of incarceration was high (13.45%). Longer wait times, infants and younger children, male sex, right sided hernias were associated with unacceptably higher rates & risks. Neonates had as much as 5 times higher risk of incarceration than other children. The best time to operate is before 3 weeks for neonates, before 2 months for infants & before 4 months for younger children to prevent incarceration.

Nyelvi szkepszis és szómágia A. A. Fet költészetében
Authors: Hajnády Zoltán
Published: January 2023

Fet költészetében a virtuóz szóhasználat nyelvi szkepszissel vegyül, beleértve a verbális kifejezőképesség tagadását és a csend apoteózisát. Költészetének fő témája a kifejezhetetlen és az elmondhatatlan, mely paradox módon kifejezhetővé és leírhatóvá válik az impresszionista képrendszernek, a metaforikus nominalizmusnak, a zeneiségnek és a metanyelvi eszközöknek köszönhetően. Fet versszövegeinek szemantikai rétegei kimeríthetetlenek.
Sötét anyag nem létezik a kepleron-koncepció alapján
Authors: Rockenbauer Antal
Published: January 2023

A kepleron-koncepció alapján értelmezzük az univerzum tágulásának Hubble-törvényét, összevetve a kozmológia sötét anyagon és sötét energián alapuló elméletével. Azt találtuk, hogy számos csillagászati megfigyelés (az Androméda-köd közeledése, a spirális karokban a csillagok azonos keringési sebessége, a galaxisforgások létrejötte, csillaghullámzás a Tejútban, a Tejút lapos felépítése, a galaxisok számának nagyságrendi becslése) egyaránt a kepleron-modell mellett szól, és ezért nincsen szükség a sötét anyag hipotézisére. A galaxisok stabilitását és szerkezetét nem a vonzóerő megnövelése magyarázza, hanem külső kompresszió, amit a távoli galaxisok idéznek elő. A galaxisok közötti antigravitáció független a távolságtól, összhangban az Einstein által bevezetett, a térben mindenütt jelenlevő kozmikus állandóval. A sötét energia valójában a galaxisok közötti taszítási energia. A kozmológia elméleti alapjait is újra kell gondolni, ősrobbanás helyett a kezdeti őskáoszból indulhatott el egy szétválási folyamat, amely a galaxisok kialakulását okozta. Az őskáosz magas hőmérsékletén az áramló töltések foglyul ejtették a fényt, majd a lehűlés vezetett el a fény kiszabadulásához, amit a mikrohullámú háttérsugárzás jelez.
论相对论和量子力学的错误
Authors:   北京市燃气集团研究院, 王 胜彬
Published: January 2023

19世纪末，在英国皇家学会迎接新世纪到来的庆祝会上，开尔文勋爵自豪地宣称：“物理学理论大厦已经建成，未来的物理学家们只需要做一些修修补补的工作就可以了。”但是在喜悦的氛围中，仍然存在着“两朵令人不安的乌云”，一朵是迈克耳孙-莫雷实验对以太速度测量的零结果，另一朵是与黑体辐射有关的紫外灾难问题。第一朵乌云催生出了相对论，第二朵乌云催生出了量子力学。相对论和量子力学被称为现代物理学的两大支柱。然而100多年过去了，相对论和量子力学却未能融合在一起，不仅如此，两者还存在着许多无法调和的矛盾。一个世纪以来，理论物理学并没有取得任何突破性进展，甚至处于停滞状态，我们再也没有听到过足以带动新物理革命的理论。相对论和量子力学无法统一可能有三种原因，1.两个理论中有一个是不正确的，2.两个理论均不正确，3.两个理论均正确，只是目前还没有找到使二者统一的方法。本文将从相对论和量子力学的核心公式出发进行数学推导和分析，进而给出答案。最后我们会发现：现代物理学理论体系选择了两朵乌云，放弃了整片天空。
“Mi sangre y mi familia”: la construcción subjetiva de un rapero y la individualidad en las clases populares del Buenos Aires contemporáneo
Authors: Muñoz Tapia Sebastián Matías
Published: January 2023

Este artículo tiene como objetivo analizar la construcción subjetiva de un rapero de Ciudad Autónoma de Buenos Aires en su obra artística y su vida cotidiana. Se plantea que la forma de elaborar su personaje público se relaciona con las categorías nativas de “jugársela” y “estar jugado”, lo que se conecta a corrientes de individualización más amplias asociadas al uso de las redes sociales, la espiritualidad de la Nueva Era, la psicologización y el propio dispositivo rapero. De esta forma —mediante el análisis de letras de canciones, video clips, posteos en Instagram, situaciones de campo y entrevistas—, se describe cómo Núcleo —el rapero en cuestión— presenta sus “fragilidades” y “fuerzas” enfatizando su activación personal y las relaciones con otros; extiende sus vínculos a las “energías”; se exhibe como alguien apegado a la “cultura hip-hop”; y como una persona responsable ante su familia. De tal modo, establece una particular relación entre lo individual y lo colectivo que permite indagar en una singular figura de individuo presente en las clases populares de la Argentina contemporánea, que se diferencia de un tipo de individualismo que se adjudica a las concepciones neoliberales.
¿De qué hablan cuando hablan de “ideología de género”? La construcción del enemigo total
Authors: Morán Faúndes José Manuel
Published: January 2023

Mediante la movilización del discurso de la “ideología de género”, actores neoconservadores están promoviendo un cuestionamiento transnacional a las políticas y teorías de género. Este discurso ha cobrado relevancia en los últimos años, logrando impactar en diversas instituciones y procesos públicos. Este artículo busca analizar sintéticamente las principales ideas que conforman el discurso de la “ideología de género”, focalizándose en el modo en que construye una frontera en un “nosotros/as” y un “otros/as”. Para ello, se analizan los escritos producidos desde los años 1990 hasta la fecha por diversos actores neoconservadores en las Américas y Europa, poniendo especial atención en aquellos que tuvieron más impacto y difusión. Luego de realizar una breve genealogía del discurso de la “ideología de género”, se propone el concepto de “enemigo total” para destacar cómo este discurso produce un imaginario donde el “otro/a” es pensado en términos epistémicos, ideológicos, morales y geopolíticos, conformando la imagen de un adversario que evoca diversos pánicos morales que alientan a la movilización. La “ideología de género”, más que un concepto orientado a describir un fenómeno, es una estrategia de movilización y convocatoria, un modelo de subjetivación política.
Las teorías de la dependencia y la pregunta por el lugar de lo político: abordajes y críticas sobre “lo interno”, “lo externo” y su relación
Authors: Tzeiman Andrés
Published: January 2023

El presente trabajo tiene como propósito indagar en un conjunto de discusiones producidas en el seno de las teorías de la dependencia, cuyo despliegue tuvo lugar en los años 1960 y 1970 en América Latina. El eje central del artículo reside en la pregunta acerca del lugar ocupado por lo político en las teorías de la dependencia, así como en una indagación de aquello que en múltiples trabajos dependentistas es abordado como los factores “internos” y “externos”, y su relación.
Frente a ciertas perspectivas que privilegian un cuestionamiento al dependentismo en virtud de la existencia de enfoques deterministas en su seno, la intención de este trabajo es dar cuenta de la heterogeneidad de miradas que convivieron en el tratamiento de la dependencia como problemática política común. En ese sentido, el artículo se propone presentar una diversidad de enfoques que contemplan desde una lectura mecánica del fenómeno hasta la inscripción en una perspectiva que pretende entroncar con el abordaje de la cuestión nacional. De esa manera, se mostrará cómo se configuran distintos modos de pensar la dimensión de lo político en el amplio espectro de los estudios dependentistas.
Para ello, se recuperan textos clásicos de distintos autores clave del universo dependentista, como Fernando H. Cardoso, Enzo Faletto, Osvaldo Sunkel, Ruy Mauro Marini, Theotonio dos Santos, Vania Bambirra y André Günder Frank, entre otros. Al mismo tiempo, se retoman algunas contribuciones que, si bien se inscriben en el locus de la dependencia latinoamericana, realizaron sus aportes en un diálogo crítico con ese conjunto amplio y heterogéneo de teorías.
