Introduction: Pregnant women are considered a high-risk group for COVID-19 due to their increased vulnerability to viral infections. The impact of COVID-19 on pregnant women is not well understood, and there is a need for data on managing severe COVID-19 in pregnant patients. This retrospective descriptive cohort study described the characteristics, hospital stay, interventions, and outcomes of pregnant patients admitted to the intensive care units (ICUs) with severe COVID-19 pneumonia in Qatar.
Methods: Data were collected from medical records and chart reviews of pregnant women admitted to Hamad Medical Corporation (HMC) with COVID-19 pneumonia from March 01, 2020, to July 31, 2021. The inclusion criteria encompassed pregnant women with a positive polymerase chain reaction (PCR) antigen test or radiological changes at admission, requiring respiratory support, and hospitalized for more than 24 hours.
Results: A total of 43 pregnant women were included in this study. Most patients were admitted during the first wave of the pandemic, with a median gestational age of 212 days [interquartile range 178–242 days] at presentation. The most common respiratory support methods were high-flow nasal cannula, non-invasive positive pressure ventilation, and invasive positive pressure ventilation. Convalescent plasma therapy was administered to 58% of patients, and tocilizumab was used in 28%. Renal replacement therapy was required by 4.6% of patients and 7% required extracorporeal membrane oxygenation.
Conclusion: This study provides valuable insights into the impact of COVID-19 on pregnant patients admitted to the ICUs in Qatar. The results suggest that pregnant patients with COVID-19 pneumonia require close monitoring and appropriate interventions to minimize adverse outcomes for both mother and fetus. The data may contribute to future guidelines and management strategies for severe COVID-19 in pregnant patients.

Published: October 2023

O estuário da Lagoa dos Patos é um importante polo pesqueiro artesanal por constituir área de criação de diversas espécies de peixes e crustáceos. Suas águas são influenciadas diretamente por fatores meteorológicos, os quais interferem na entrada de água oceânica no estuário e na vazão, refletindo na sua salinidade. Por esta razão, há a possibilidade de V. parahaemolyticus ser encontrado no estuário da lagoa e, consequentemente, nos pescados nele capturados, o que ofereceria risco aos consumidores. O objetivo do estudo foi de avaliar a presença de V. parahaemolyticus em pescados do estuário da Lagoa dos Patos, capturados e processados artesanalmente. Cinquenta e seis amostras de pescados oriundos do estuário da Lagoa dos Patos foram analisadas quanto à presença de V. parahaemolyticus. Três das cinco espécies analisadas, camarão-rosa (Farfantepenaeus paulensis), tainha (Mugil platanus) e linguado (Paralichthys orbignyanus) albergavam o micro-organismo pesquisado. Estes resultados servem de alerta para a necessidade de maior fiscalização na produção de pescados, bem como da adoção de medidas higiênico-sanitárias que previnam o risco de transmissão deste patógeno para os consumidores. Este é o primeiro registro de isolamento de V. parahaemolyticus de F. paulensis, M. platanus e P. orbignyanus.

This study carried out an analysis of social media and entrepreneurship development nexus in Benue State. The researcher used mainly primary data from a sample of three hundred entrepreneurs in Zone A, B & C in Benue State Nigeria. The primary data was obtained using a structured questionnaire. The data collected were analyzed using logit regression to establish the relationship between social media and entrepreneurship development while principal component analysis was used to identify the most important factors that affects the use of social media in entrepreneurship development. The result of the binary logistic regression analysis indicates that Social Media added significantly to the model/prediction. This means that the logistic model was statistically significant at 5 percent level of significance. Increasing the use of social media was associated with an increased likelihood of entrepreneurship development in Benue State. The logistic regression model was statistically significant, using values from the Omnibus Test of Model Coefficient. The model explained of the variance in post harvest losses of orange in the studied areas and correctly classified of cases. Use of social media was 0.018 times more likely to bring about entrepreneurship development in the studied areas. It was concluded that social media have a positive and significant effect on entrepreneurship development in Benue State Nigeria. It was recommended among others that entrepreneurs in the study area should engage more qualified personnel who can create the right content needed to engage the diverse customers of the business. When this is done, the likelihood of the use of social media in bringing about entrepreneurship development in Benue State can be increased.
Self-Efficacy in Early Childhood Educators: The Impact of Online Teaching During the COVID-19 Pandemic
Authors: Guirguis Ruth , Plotka Raquel 
Published: October 2023

Due to the COVID-19 pandemic, several early childhood education programs in the United States and around the world were forced to shift to online instruction. While virtual learning was found to be challenging for all age groups, this mode has been especially challenging for early childhood educators. The present study explored the challenges that teachers faced when adjusting their early childhood education practices to an online format during the COVID-19 health crisis and also explored those activities that teachers found most effective. Furthermore, this study explored the role of online teaching in teachers’ senses of self-efficacy and assessed whether support from families and program administration played a role in teacher self-efficacy. Lessons for the role of online education in early childhood, with implications for practice, are discussed. As online instruction becomes more prominent in all areas of education, the lessons learned during the pandemic should prove informative long after the crisis is overcome.

How can creation occur by ‘drawing from masters’ drawings’ in undergraduate Graphic Design courses (a proposal)?
Authors: Gomes De Oliveira Caiado Fátima 
Published: October 2023

In this essay, we readdress manual observational drawing, in drawing classes of graphic design undergraduate courses. Our teaching proposal supports itself on exploratory, and empirical research studies as well as cognitive applied research: 1st validating that - through copying-imitating other artists’ drawings, students can achieve creative outputs and develop other drawing fundamental skills identified as essential for graphic designers; 2nd how that can happen throughout - drawing from masters’ drawings -, suggesting teaching strategies, deducted from five identified cognitive mechanisms fostering creativity - "reinterpretation" or "constraint relaxation"; "flexible abstraction"; "combinations"; "borrowing structure" or "mapping", and "find a new problem space".

The global COVID-19 pandemic has had impact not just on physical health, but also on mental health, particularly among undergraduate students. Previous studies have demonstrated that Computer Science students in particular already exhibit more symptoms of anxiety and depression than the general population and students in other fields. The study aimed to measure the impact of COVID-19 on Computer Science students' mental health, by assessing the prevalence and associated factors of anxiety and depression symptoms, and the factors that most affected their well-being. An online cross-sectional survey focused on concerns and impacts of COVID-19 was designed. The Beck Anxiety and Depression Inventories were used to measure the anxiety and depression symptoms. The data were anonymously collected, and analyzed using the TIBCO Statistica™ software, by non-parametric tests. 174 students (135 males; age=21.07±2.47 years) participated in the study. The prevalence of symptoms was 36.7% for anxiety and 60.3% for depression. 81% of students reported that their well-being had been negatively affected by the pandemic, with the most reported concerns including social isolation and delay in academic progress. Correlations between anxiety and depression symptoms, strong social relationships, regular practice of physical exercise, and students' level of satisfaction with their academic program were found. This paper sheds light on the impact of the COVID-19 pandemic on CS students' mental health, suggests ways in which Computer Science students may be able to reduce symptoms of anxiety and depression, and improve their mental health during and after the pandemic.
On the consistency of hysteresis models
Authors:   , Fuad Mohammad Naser Mohammad 
Published: October 2023

Hysteresis is a nonlinear behavior encountered in a wide variety of processes including biology, optics, electronics, ferroelectricity, magnetism, mechanics, structures, among other areas. One of the main features of hysteresis processes is the property of consistency formalized in [52]. The class of operators that are considered in [52] consists of the causal ones, with the additional condition that a constant input leads to a constant output. For this class of systems, consistency has been defined formally. This property is useful in system modeling and identification as it limits the search for the system's parameters to those regions where consistency holds.
The thesis applies the concepts introduced in [52] to some hysteresis models, namely LuGre model and Duhem model. The aim of the thesis is to derive necessary conditions and sufficient one for consistency (or/and strong consistency) to hold.
For the LuGre model, the consistency and the strong consistency are studied under minimal conditions in Chapter 2. As a by-product of this study, explicit expressions are derived for the hysteresis. Such expression may be useful for identification purposes as shown in [53].
A classification of the possible Duhem models in terms of their consistency is carried out in Chapter 3. This study shows that a parameter’s should be one for the Duhem model to be compatible with a hysteresis behavior.
La histéresis es un fenómeno nolineal encontrado en varios procesos como biología, óptica, electrónica, ferroelectricidad, magnetismo, mecánica, estructuras, así como en otras áreas. Una de las características de los sistemas con histéresis es la propiedad de consistencia formalizada en [52]. La clase de operadores considerados en [52] consiste en aquellos que son causales, con la condición adicional que a una entrada constante corresponda una salida constante. Para esta clase d sistemas, la consitencia ha sido definida formalmente. Esta propiedad es útil en modelado e identificación dado que limita la búsqueda de parámetros a aquellas regiones donde la consistencia es válida.
* Esta tesis aplica los conceptos introducidos en [52] a algunos modelos de histéresis, más precisamente al modelo de LuGre y al modelo de Duhem. El objetivo de esta tesis es encontrar condiciones necesarias y condiciones suficientes para que se satisfaga la consistencia (o/y la consitencia fuerte).
* Para el modelo de LuGre, la consistencia "fuerte" se estudia en el capítulo 2 bajo condiciones mínimas. Como resultado de este estudio, se hallan fórmulas explícitas del lazo de histéresis. Tales fórmulas podrían ser de utilidad para tareas de identificación como se demuestra en [53].
* El capítulo 3 de la tesis presenta una clasificación de los modelos de Duhem posibles en términos de su consistencia. Este estudio muestra que hay un parámetro que tiene que valer uno para que el modelo sea compatible con un comportamiento histerético

Authors:   , Cánovas Bermejo Catalina 
Published: October 2023

The present thesis is undertaken to study the use of an aqueous solution of LiCl as a secondary refrigerant, due to its dehydrating properties, in those refrigeration applications that require mainly the air dehumidification and where the conventional methods show technical difficulties and/or a high energetic cost.
The study of mass and heat transference between the aqueous solution of LiCl and the air is made, and it is applied to different conditions of dry temperature and air relative humidity.
Regeneration of the aqueous solution of LiCl is solved using the condenser thermal power from the same refrigeration circuit, removing the dependence on other external heat sources, thus increasing the installation energetic efficiency.
The analysis of the obtained results and the energetic comparative regarding to the conventional methods used so far show this is really an alternative to consider.
En la presente tesis doctoral se acomete el estudio del uso, gracias a sus propiedades deshidratantes, de una solución acuosa de LiCl como refrigerante secundario, en aquellas aplicaciones frigoríficas que requieren principalmente la deshumidificación del aire y donde los métodos convencionales presentan dificultades técnicas y/o elevado coste energético. Se realiza el estudio de la transferencia de masa y calor entre la solución acuosa de LiCl y el aire y se aplica a diferentes condiciones de temperatura seca y humedad relativa del aire. Se resuelve la regeneración de la solución acuosa de LiCl utilizando la potencia térmica del condensador del mismo circuito frigorífico, eliminando así la dependencia de otras fuentes de calor externas y aumentando la eficiencia energética de la instalación. El análisis de los resultados obtenidos y la comparativa energética respecto a los métodos convencionales que se utilizan hasta ahora, muestra que es una alternativa a considerar.
Place, sketch and architecture : an in-situ approach to contemporary design.
Authors:   , Harris Sebastian Francis 
Published: October 2023

Esta tesis analiza cómo el croquis in-situ puede profundizar la conexión entre la arquitectura y el lugar en todas las etapas del proceso proyectual. La primera parte considera cómo el croquis in-situ puede estructurar las percepciones de lugar, subjetividad y tiempo, integrándolas en el proceso creativo. La segunda parte investiga las relaciones conceptuales subyacentes entre los dibujos de viaje y bocetos de proyecto a través del análisis comparativo de los dibujos de Le Corbusier y Alvaro Siza. En la tercera parte se utilizan los croquis del propio autor para examinar las complejas relaciones entre el lugar y los bocetos de proyecto centrándose en las siguientes obras: la Acrópolis, Can Lis (Jorn Utzon) y el Mercado de Santa Caterina (EMBT). La cuarta parte presenta estos argumentos teóricos en un cuaderno de bitácora, trazando una secuencia de relaciones interconectadas entre la arquitectura y el lugar utilizando ejemplos de todo el mundo. Se utilizan bocetos y diagramas del autor para argumentar cómo el croquis in-situ es un proceso mental complejo que combina la observación de la realidad con el proceso proyectual. Además, el croquis in­situ construye una comprensión estratificada del lugar y del tiempo que forman la base esencial del pensamiento y diseño arquitectónico.
This thesis analyses bow sketching in-situ can deepen the connection between architecture and place throughout all stages of the design process. Part one considers how in-situ sketching can structure human centered perception s of place, subjectivity and time, integrating them positively into the creative process. Part two investigates underlying conceptual relationships between travel drawings and design sketches through comparative graphic analysis of the sketches of Le Corbusier and Alvaro Siza. In part three, the author's own in-situ sketches scrutinize the complex and contrasting relationships between place and architecture focusing on the Acropolis, Can Lis (Jom Utzon) and Santa Caterina Market (EMBT). Part four presents these theoretical arguments as a graphic logbook, charting a sequence of interconnected relationships between architecture and place from around the globe. The author’s sketches and diagrams are used to argue how in-situ drawing involves a complex though t process which combines observation of reality with the design process. It constructs a layered understanding of place and time, forming the essential basis of architectural thought and design
Seven new narrowly endemic species of Gulella Pfeiffer, 1856 from eastern South Africa (Gastropoda, Streptaxidae) and status revision for another
Authors: Cole Mary L. , Herbert David G. 
Published: October 2023

Seven new species of very small Gulella Pfeiffer, 1856 are described from two regions in the interior of south-eastern South Africa within the Maputaland-Pondoland-Albany biodiversity hotspot. In addition, the status of Gulella darglensis benthodon van Bruggen, 1980 is revised and raised to species level. All species are very small-shelled and are narrow-range endemics. Six species, G. judithmastersae sp. nov., G. kevincolei sp. nov., G. hlathikhulu sp. nov., G. nkandla sp. nov., G. mystica sp. nov. and G. libertas sp. nov. are each known from only one locality. The first two as well as G. benthodon and G. mcmasteri sp. nov. are found only in the Amathole Mountains, where poaching, illegal harvesting of plant products and uncontrolled access of cattle take place, including in protected areas. The other four species each occur at one locality in north-central KwaZulu-Natal. The localities of three of the last-mentioned species are in protected areas although they are isolated and surrounded by a heavily transformed cultural landscape rendering enforcement of conservation legislation a challenge. Six species occur in nature reserves, highlighting the importance of small pockets of protected habitat for the conservation of terrestrial snails.

Pendidikan adalah usaha sadar dan terencana untuk mewujudkan proses pembelajaran agar peserta didik secara aktif mengembangkan potensi dirinya untuk memiliki kekuatan spiritual keagamaan, pengendalian diri, kepribadian, kecerdasan, akhlak mulia, serta keterampilan yang diperlukan dirinya, masyarakat, bangsa, dan negara, Dalam praktiknya, tujuan pendidikan yang telah ditetapkan tidak selamanya dapat tercapai penuh seperti yang diharapkan, karena dipengaruhi oleh beberapa faktor yang mendasar. Berdasarkan pengamatan guru sebagai peneliti, proses pembelajaraan di kelas XI KIA SMKN 2 Depok, belum menggunakan model pembelajaran yang membuat peserta didik lebih aktif dan kreatif dalam pembelajaran. Sebagian besar peserta didik merasa segan bertanya, menjawab dan merespon diskusi antar teman. Pada proses pembelajaran guru masih banyak menggunakan metode yang konvesional jika dilihat dari metodenya dan medianya. Tingkat keberhasilan peserta didik dalam penguasaan kompetensi pengetahuan dan kompetensi keterampilan dari nilai yang ada ketuntasan belajarnya hanya mencapai 57 %. Oleh karena itu peneliti bermaksud untuk meningkatkan karakter kerja peserta didik melalui model pembelajaran problem based learning (PBL). Pada penelitian ini dengan metode tersebut dapat meningkatkan prestasi belajar peserta didik dari 74,14 pada siklus I menjadi 97,72 pada siklus II. Penerapan model problem-based learning (PBL) dapat meningkatkan aktivitas belajar dari 60% di Siklus I dan meningkat menjadi 80% pada Siklus II.
