Published: May 2021

Introduction: Limited data exist on clinical characteristics and outcomes of hospitalized COVID-19 patients in low-middle income countries. We aimed to describe the clinical spectrum and outcomes of hospitalized COVID-19 patients at a tertiary-care center in Karachi, Pakistan.
Methodology: We conducted an observational study of adult COVID-19 patients hospitalized between February-June 2020. Patients with a discharge diagnosis of COVID-19 and PCR positivity were included. We created logistic regression models to understand association of clinical characteristics with illness severity and in-hospital mortality.
Results: The study population comprised 445 patients [67% males, median age 53 (IQR 40-64) years]. Majority of patients (N = 268; 60%) had ≥ 1 co-morbid [37.5% hypertension, 36.4% diabetes]. In-hospital mortality was 13%. Age ≥ 60 (aOR] =1.92; 95 %CI = 1.23-3.03), shortness of breath (aOR=4.43; 95% CI=2.73-7.22), CRP ≥150mg/L (aOR:1.77; 95% CI=1.09-2.85), LDH ≥ 500 I.U/L (aOR:1.98; 95% CI=1.25-3.16), Neutrophil-to-Lymphocyte ratio (NLR) ≥5 (aOR:2.80; 95%CI = 1.77-4.42) and increase in serum creatinine (aOR:1.32; 95%CI=1.07-1.61) were independently associated with disease severity. Septic shock (aOR: 13.27; 95% CI=3.78-46.65), age ≥ 60 (aOR: 3.26; 95% CI=1.07-9.89), Ferritin ≥ 1500ng/ml (aOR: 3.78; 95% CI=1.21-11.8), NLR ≥ 5 (aOR: 4.04; 95% CI=1.14-14.35) and acute kidney injury (aOR: 5.52; 95% CI=1.78-17.06) were independent predictors of in-hospital mortality.
Conclusions: We found multiple predictors to be independently associated with in-hospital mortality, except diabetes and gender. Compared to reports from other countries, the in-hospital mortality among COVID-19 patients was lower, despite a high burden of co-morbidities. Further research is required to explore reasons behind this dichotomy.
Diplomatie et distinction. La fonction du journal d’un noble vers 1800
Authors: Ackermann Nadja 
Published: May 2021

Quelles pouvaient être les raisons motivant un noble à se consacrer au service diplomatique d’un prince au xviii e siècle ? En abordant cette interrogation, l’article s’inscrit dans les recherches récentes sur les pratiques diplomatiques à l’époque moderne, tout en cherchant à les développer dans deux directions. D’une part, l’identification du cadre de pensée d’un envoyé poursuit, en les élargissant, les approches centrées sur les acteurs dans l’histoire sociale et relationnelle des diplomates. D’autre part, cette analyse, menée pour un acteur diplomatique vers 1800, contribue à un élargissement chronologique de ce champ de recherches, dont les études prennent le plus souvent la Révolution française comme point final ou comme point de départ. Il est possible de mettre en œuvre cette double ouverture de l’histoire sociale des diplomates grâce aux écrits du for privé du patricien neuchâtelois Jean-Pierre de Chambrier d’Oleyres (1752-1822), envoyé prussien à Turin (1780-1805) et en Suisse (1805-1816). Au plan méthodologique, l’article suit une approche praxéologique, telle qu’elle a été introduite dans la recherche sur les écrits du for privé. Prenant comme point de départ la pratique de l’écriture du journal chez le diplomate Chambrier d’Oleyres (un journal de 51 volumes soit plus de 20000 pages), cette contribution vise à souligner les bénéfices d’un rapprochement de deux champs dynamiques de l’historiographie jusqu’à présent rarement mis en rapport, à savoir la nouvelle histoire diplomatique et la recherche sur les égo-documents.
L’impossible asile. La maison des aliénés de Corsier (1832-1838)
Authors: Cicchini Marco , Maugué Ludovic 
Published: May 2021

Entre 1832 et 1838, dans le village de Corsier à proximité de Genève, une bâtisse rurale est transformée en établissement public pour aliénés. Passée sous silence ou considérée comme une simple parenthèse par l’historiographie de la conquête asilaire en Suisse, cette expérience est modeste par sa durée et par sa taille. Elle illustre pourtant de manière condensée les obstacles, les échecs et les hésitations qui entourent, dans la première moitié du xix e siècle, la création d’établissements spécialisés dans le domaine de la maladie mentale. La maison de Corsier est exemplaire de ce temps où les savoirs, les acteurs et les lieux de la psychiatrie naissante sont largement indéterminés, où le monopole médical sur la folie est même une lointaine chimère. Le choix de s’établir à Corsier n’est pas le produit des circonstances sanitaires – l’épidémie de choléra menace la Suisse – mais le résultat d’une conception de l’aliénation mentale nouant l’ambition thérapeutique aux exigences d’ordre public et de gestion administrative de l’anormalité psychique ou sociale. Dans sa forme et son mode de fonctionnement, la maison de Corsier est l’un de ces lieux de folie mal circonscrits, parmi d’autres en Suisse et en Europe, entre l’hôpital général et l’asile.

L’automobile de demain : une histoire de générations déçues
Authors: Mom Gijs 
Published: May 2021

Cet article est la première synthèse d’un ouvrage de 400 pages publié en 2004 (note 1). L’argumentation se fonde d’abord sur la déconstruction d’explications généralement apportées par des ingénieurs pour comprendre l’échec du véhicule électrique. Autrement dit, si nous l’avions choisi, nous aurions pu rouler à l’électricité sans problème. Face aux arguments techniques, l’auteur avance une hypothèse culturelle selon laquelle la voiture électrique est en fait un succès dans la mesure où elle est parvenue à stimuler la voiture à pétrole dans ses perfectionnements techniques. En l’absence d’analyse plus poussée sur la seconde moitié du xxe siècle, il convient de s’interroger sur notre changement d’opinion sur la faisabilité de la voiture électrique. En avons-nous réellement changé ? Devons-nous réellement le faire ?
Dessiner à l’Université ? Esquisse d’un cheminement
Authors: Herrmann Lou 
Published: May 2021

Le dessin peut-il être une écriture académique ? Peut-il participer à la diffusion et la construction des savoirs scientifiques ? À l’instar d’une épaisse histoire qui lie géographie et dessin, ce texte fait l’hypothèse que oui. Revenant sur ma pratique du dessin en milieu académique, j’explore ses attributs propres et esquisse les potentialités de sa mobilisation dans le travail de recherche en sciences sociales. Il se révèle être, selon les cas, un formidable outil de traduction, de synthèse, d’enquête ou d’abstraction.
Tourisme rouge, tourisme noir : le cas des memorial parks chinois
Authors: Mariet Vincent 
Published: May 2021

Depuis une trentaine d’années, le tourisme de mémoire se mue en un tourisme de masse. En Chine, il se dilue dans un « tourisme rouge » officiel qui lui-même s’insère dans un processus global de thanatourisme. Les anciens champs de bataille, espaces mémoriels sacralisés, sont maintenant le théâtre d’une mise en divertissement sous la forme de memorial parks. Cet article a pour objectif de montrer comment et par quels moyens est représentée la mort due à la guerre et quelle est alors la place des morts dans ces lieux historiques au passé sombre.
Le monde chinois des morts dans l’œuvre de Paul Claudel
Authors: Chu Ge 
Published: May 2021

Cet article s’intéresse aux représentations du monde chinois des morts dans l’œuvre de Paul Claudel. Nous prêtons attention au regard claudélien sur les tombes chinoises, sur la notion de l’enfer dans les contextes occidental et chinois, et enfin sur la relation entre les vivants et les morts de la Chine. Une telle enquête nous aide certainement à mieux comprendre les écrits chinois de Claudel ; de plus d’après nous, le regard de Claudel constitue un échange culturel et philosophique concernant les attitudes envers la vie et la mort en Chine et en Occident.

Geochemistry of volcanic flows of Nakora area of Malani igneous suite, Northwestern India: Constraints on magmatic evolution and petrogenesis
Authors: Kumar Naresh , Kumar Naveen 
Published: May 2021

The geochemical characteristics of volcanic flows of Nakora area of Malani Igneous Suite have been determined to understand their magmatic evolution and petro-genetic aspects. Geochemically, they are high in silica, total alkalis, high field strength elements (HFSE), low ion lithophile elements (LILE), rare metals and rare earth elements; represent A-type affinity with potential mineralization associations. Here, we carried out average geochemical data bank of representative samples of 44 individual lava flows of isolated hill-locks. The relative enrichment of trace elements and negative anomalies of Sr, Eu, P and Ti in the multi-element spider diagrams suggests that the emplacement of the lava flows was controlled by complex magmatic processes i.e. fractional crystallization, partial melting, magma mixing, crustal contamination and assimilation. Moreover, NRCmagma provides new geochemical approaches to understand geodynamic evolution of MIS and emplaced in plume related extensional geodynamic settings in NW Indian shield.

Novel flattened gain using RAMAN-Erbium doped silica fiber hybrid optical amplifier for super dense wavelength division multiplexing system
Authors: Kumar Chakresh , Kumar Ghanendra 
Published: May 2021

We have proposed a very advanced super dense wavelength division multiplexing (SD-WDM) system using RAMANErbium doped silica fiber optical amplifier (EDSFA) hybrid optical amplifier (HOA) in this paper. Performance is evaluated in term of flattened gain and noise figure for C-band. Effect of proposed hybrid optical amplifier also compared with EDFARAMAN, EDFA-SOA and SOA-SOA HOA for the same characteristics. Best rating gain of 37.5 dB with noise figure of 5.4 dB ever recorded from RAMAN-EDSFA HOA. It is also observed that out come from SOA-SOA HOA is not acceptable in term of noise figure of 9.1 dB for 400 x 10 GB/s SD-WDM system.

Protection of wind park connected series capacitor compensated three-phase transmission line using RBWT
Authors: Kapoor Gaurav 
Published: May 2021

This paper proposes the RBWT (reverse biorthogonal-1.5 wavelet transform)-based fault recognition and faulty phase categorization technique for the protection of wind park connected series capacitor compensated three-phase transmission line (WPCSCCTPTL). The single side captured fault currents of the WPCSCCTPTL are used to evaluate the amplitudes of RBWT coefficients at fifth level. To authorize the performance of the proposed technique, a widespread collection of simulation studies have been done thus varying fault type, location, resistance, and switching time. In this work, the performance of the RBWT has been investigated for the evolving faults, the position of fault for the close-in relay faults is varied from 5 km up to 9 km, the position of fault for the far-end relay faults is varied from 195 km up to 199 km, faults at two different positions, the position of fault around the series capacitors are changed and for the variation in wind-turbine units. The benefit of RBWT is that it correctly detects all types of faults in WPCSCCTPTL by employing one-side fault current data only. It is also investigated that the proposed technique is robust to the variation in the fault factors of WPCSCCTPTL.
Keywords: fault recognition, faulty phase categorization, three-phase transmission line protection, reverse biorthogonal-1.5 wavelet transform.
The analysis of truncated ARQ and HARQ schemes using transition diagrams
Authors: Kundaeli Herald N. 
Published: May 2021

In digital communication systems, ARQ and HARQ schemes are employed in order to ensure efficient transmission of information and utilisation of the channel by retransmitting information that has not being received correctly at the receiver. In some applications, however, such as real-time services, the quality of information is degraded if too many retransmission trials are employed for each unit of erroneously received information. The retransmissions are therefore limited leading to truncated ARQ and HARQ schemes. In this study we develop a new method for deriving the expressions for the throughput efficiencies of truncated ARQ and HARQ schemes and investigate how the efficiencies vary with the number of allowed retransmissions.
Keywords: ARQ, HARQ, Throughput Efficiency, Truncated ARQ.
Multi attribute decision making parametric optimization in weld bead by gas metal arc welding through grey relation analysis: A case study
Authors: Rizvi Saadat Ali , Ali Wajahat 
Published: May 2021

The basic purpose of this study was to identify the effect of gas metal arc (GMA) welding process parameters on the weld bead geometry of IS2062 structural steel of A grade. L16 Taguchi orthogonal array (OA) design with the idea of S/N (signal to noise) ratio was applied to obtain objective function to be optimized within the experimental field. In this research work the Taguchi technique was joined with grey relational analysis to solve the multi-response optimization problem. ANOVA (Analysis of Variance) was applied to estimate the most significant input parameters which contribute toward the output parameters. Arc voltage, gas flow rate, and wire feed speed were carefully selected as input parameters, whereas weld bead, depth of penetration, and reinforcement were output respectively. The optimal GMA welding process parameters were identified in order to enhance the productivity and curtail the overall functional cost of weld.
Keywords: grey-relational analysis (GRA), Taguchi technique, optimization, GMAW, ANOVA.
Personal resilience and its influence on COVID-19 stress, anxiety and fear among graduate students in the Philippines
Authors: Oducado Ryan Michael , Parreño-Lachica Geneveve , Rabacal Judith 
Published: May 2021

The COVID-19 pandemic is putting new and unforeseen pressures and has resulted in substantial disruption in the lives of the people across the globe. Although there is a budding body of literature on the impact of COVID-19 on mental health and psychological well-being, little research has been published among Filipino Graduate students in the context of a pandemic. This descriptive-correlational, cross-sectional research examined the relationship of resilience on COVID-19 perceived stress, anxiety, and fear. Two-hundred and three Graduate students participated in the online survey conducted in the last week of August 2020. Four self-reported questionnaires were used to gather the data. Descriptive statistics and correlational analysis were performed. Results indicated that the composite scores of the COVID-19 stress, anxiety, and fear were 2.81 (SD=.605), 3.94 (SD=.686), and 3.03 (SD=1.004) respectively. The composite score on the resilience scale was 3.33 (SD=.496). COVID-19 stress and fear had significant inverse correlation with resilience. Resilience has a protective influence on COVID-19 fear and is pivotal to cope with COVID-19 stress. Educational institutions may need to cultivate and harness the resilient trait of Graduate students in the midst of pandemic and other stressful events to help combat negative mental states and undesirable psychological consequences.

Published: May 2021

The COVID-19 crisis practically magnified the normal fear of people, bringing other negative psychological outcomes such as job burnout. Building on this assumption, this paper aimed to compare fear of COVID-19 and remote teaching burnout across sample characteristics and relate fear of COVID-19 to the remote teaching burnout. Following comparative and correlational research designs, a sample of 1069 K to 12 Filipino teachers was selected to participate in the online survey. The data were analyzed using descriptive and inferential statistics. The results showed that the teachers have a high level of fear of COVID-19 and a moderate level of remote teaching burnout. Furthermore, COVID-19 fear of teachers did not significantly differ across all sample characteristics tested; however, remote teaching burnout significantly differed across age, monthly income, educational attainment, and teaching experience, except gender. It was further revealed that there is a positive and moderate significant relationship between fear of COVID-19 and remote teaching burnout. This linear association implies that as fear of COVID-19 of teachers increases, their remote teaching burnout also increases. Considering the current persistence of COVID-19 cases and the role of teachers in the anticipated recovery phase of education, the results of the study indicate the urgent attention of education authorities to develop measures to address the needs of teachers who may have psychological issues brought by fear of COVID-19 and remote teaching burnout.
