Kyrle’s Disease: A Case Report and Literature Review
Authors: Macca Laura , Vaccaro Federico , Pomi Federica Li , Borgia Francesco , Vaccaro Mario
Published: February 2023

BACKGROUND: Perforating dermatoses are heterogeneous skin disorders characterized by transepidermal elimination of dermal tissue components. They can be characterized by the primary or secondary pathogenesis. Primary perforating dermatoses can be divided into four types, according to the eliminated dermal materials: Kyrle disease, perforating reactive collagenosis, elastosis perforans serpiginosa, and perforating folliculitis. The secondary form is also known as acquired perforating dermatosis and designates adult patients with coexisting systemic diseases, regardless of the dermal materials eliminated. The aim of this review is to investigate the potential relationship between Kyrle disease and associated conditions, reporting a rare case of this disease in a patient with chronic kidney disease.
CASE PRESENTATION: We report the case of a 55-year-old male patient who presented generalized pruritus and skin lesions on the upper limbs and trunk for about 6 months. Pathological history revealed systemic arterial hypertension and chronic kidney disease (CKD), for which the patient had been on hemodialysis since more than 3 years.
CONCLUSION: We reviewed the literature, reporting a rare case of KD in a patient with chronic renal failure on hemodialysis. KD is an acquired dermatologic condition that lacks a standardized treatment approach and can be notoriously difficult to cure. This article provides an overview of the most frequent comorbidities and treatment methodologies previously reported in the literature. If KD is suspected, underlying systemic disorders need to be investigated.

Des relations éphémères. Une sociolinguistique du tourisme
Authors: Jaworski Adam , Thurlow Crispin
Published: February 2023

Dans cet article, nous présentons une analyse de quatre types d’échanges linguistiques différents dans le domaine du tourisme. Ce faisant, nous démontrons que l'emprunt, l'appropriation et la réévaluation de la langue/des langues sont une caractéristique centrale des interactions entre hôtes et touristes. Ensemble, ces échanges linguistiques mettent en évidence la base sociolinguistique des relations éphémères ou transitoires du tourisme. À travers ces moments de contact, les hôtes et les touristes négocient la nature de leur expérience, les significations de la culture et du lieu, ainsi que leurs propres relations et identités. C'est également là où se promulguent et concrétisent de nombreuses significations de la mondialisation.
Placer les victimes au centre. Jalons psychologiques et thérapeutiques
Authors: Angeneau Lorraine
Published: February 2023

L’approche psychologique permet de reconnaître les souffrances éprouvées par de nombreuses personnes victimes en bénéficiant de leur propre expertise, tout en la confortant par la validation de leur expérience. Le diagnostic de trauma, d’abord fondé sur la présence de symptômes, est étayé par l’imagerie cérébrale. Les soins visent à une réduction fonctionnelle des symptômes, par distanciation ou prise de contrôle. La thérapeutique doit assurer sécurité au présent, apprendre à vivre avec ses symptômes, solliciter des ressources intérieures permettant de retrouver un sentiment de contrôle suffisant sur le présent, du sens et des projets. La formation est aussi essentielle pour sortir de notre surdité ecclésiale et aider les personnes à prendre soin de leur corps et de leur psychisme.
Repenser l’autorité des ministres ordonnés
Authors: Grieu Étienne
Published: February 2023

Le rapport de la CIASE interroge l’Église sur la manière de concevoir l’autorité des ministres ordonnés, obligeant à remettre sur le métier cette question. La présente contribution propose, dans cette perspective, de repartir de deux sources : l’autorité du Christ, telle qu’elle est présentée dans les Évangiles et le jeu responsorial que la liturgie met en œuvre. Un des traits de l’autorité du Christ ressort particulièrement : elle consiste en bonne partie à reconnaître l’autorité d’autres acteurs, le plus souvent totalement inattendus à cet endroit.
Abus sexuels dans l’Église et enseignement de la morale sexuelle
Authors: de Longeaux Jacques
Published: February 2023

« L’excès paradoxal de fixation de la morale catholique sur les questions sexuelles » que point le rapport de la CIASE tient davantage à la précision et à la rigueur des interdits moraux qu’à la quantité d’interventions du Magistère. La défense de l’institution du mariage a laissé dans l’ombre les abus sexuels et négligé la souffrance des victimes. Un enseignement renouvelé de morale sexuelle devrait mettre positivement en avant la dimension relationnelle de la sexualité humaine, ses valeurs, les vertus nécessaires pour les vivre, mais aussi formuler des interdits contre toute forme de violence, d’appropriation et d’assujettissement. Une section spéciale du Catéchisme de l’Église catholique pourrait être consacrée aux « violences sexuelles contre les personnes ».

Published: February 2023

Dans un contexte favorisant l’implication des parents dans la scolarité de leurs enfants, nous présentons l’application ClassDojo et les particularités de ses fonctionnalités de communication et récompenses. Nous avons mené un travail de terrain à l’école primaire, auprès des enseignants, des élèves de CE2 mais aussi de certains parents d’élèves. Il s’agissait d’interroger les apports et les effets de la plateforme, les appropriations différenciées qui ont été menées et les problèmes que posent certaines formes d’utilisations, notamment autour des récompenses. Le travail montre l’écart entre des projets numériques soutenus par les institutions éducatives et leur mise en œuvre avec les différents acteurs dans et autour de l’école, qui peut renforcer les inégalités.

Cet article porte sur la contribution des sciences de la vie à la recherche sur l’intervention dans le cadre des activités de raquette. Sous la forme d’un entretien avec Caroline Martin, spécialiste de l’analyse biomécanique du service en tennis, la réflexion se développe autour de plusieurs interrogations : (1) Quels sont les objectifs, les méthodes et les principaux résultats de ces recherches ? ; (2) A quelles conditions peut-on s’assurer d’une réelle utilité sociale de ces travaux scientifiques pour les intervenants ? ; (3) Dans le cadre du développement actuel des méthodes mixtes en STAPS, comment articuler les données extrinsèques (par exemple biomécaniques) avec des données plus intrinsèques de l’activité des sportifs ? ; (4) Si ces recherches portent pour l’instant sur le service, dans quelle mesure est-il possible de travailler sur d’autres dimensions de l’activité du joueur de tennis, et plus globalement sur d’autres activités de raquette ?
Global solvability of a chemotaxis-haptotaxis model in the whole 2-d space
Authors: Liu Meng , Li Yuxiang
Published: February 2023

This paper investigates a two-dimensional chemotaxis-haptotaxis model

   \begin{document}$ \begin{eqnarray*} \left\{\begin{array}{lll} u_t = \Delta u-\chi\nabla\cdot(u\nabla v)-\xi\nabla\cdot(u\nabla w),&{} x\in\mathbb{R}^2,\ t>0,\\ v_t = \Delta v-v+u,&{}x\in\mathbb{R}^2,\ t>0,\\ w_t = -vw,&{}x\in\mathbb{R}^2,\ t>0, \end{array}\right. \end{eqnarray*} $\end{document}

where $ \chi $ and $ \xi $ are positive parameters. It is proved that, for any suitable smooth initial data $ (u_0, v_0, w_0) $, this model admits a unique global strong solution if $ \left\|u_0\right\|_{L^1} < \frac{8 \pi}{\chi} $. Compared to the result by Calvez and Corrias (Calvez and Corrias, 2008 [1]), we can see that the haptotaxis effect is almost negligible in terms of global existence, which is consistent with the result of bounded domain (Jin and Xiang, 2021 [2]). Moreover, to the best of our knowledge, this is the first analytical work for the well-posedness of chemotaxis-haptotaxis system in the whole space.

Published: February 2023

Introduction: Hypogonadism and inﬂammato-ry bowel disease (IBD) are often associated. This association may inﬂuence sexual and reproductive function in IBD, including sperm proﬁle and sex steroid hormones. Patients and methods: This study included 59 IBD patients diag-nosed with ulcerative colitis type IBD. Anamnesis was carried out regarding the history of the disease, along with a history of rectal bleeding. Evaluation proceeded with sperm and hormone examination if the patient agreed.Results: Progressive motility sperm, immotile sperm, and normal sperm were found to be signiﬁcantly different between the rectal bleeding groups. In grade 3 (more signiﬁcant bleeding) progres-sive sperm (24.81 ± 5.85, p < 0.0001) and normal sperm (6.33 ± 12.56, p = 0.0003) rates tended to be lower, while immotile sperm tended to be higher (44.48 ± 11.21, p < 0.0001). Testosterone and free testosterone levels were also reported to be signiﬁcantly different between groups, where grade 3 had lower levels 255.9 ± 30.08, p = 0.014 and 4.645 ± 0.5, p = 0.002 respectively.Conclusions: Our study shows that the degree of rectal bleeding inﬂuences sperm motility and morphology, as well as testos-terone and free testosterone levels. These results can concern managing IBD patients to fulﬁll reproductive health care.

Religion is among the determinants of human beliefs and values in various societies, shaping people’s behaviours in a range of life aspects, including the workplace. In view of the influence of religion in Malaysia, this issue becomes highly significant. With regard to the profound impact of religion on creating individual and collective behaviours, the present study aims to investigate the effects of religious behaviours (RBs) on organisational commitment (OC) among Malaysian healthcare workers (HCWs) in 2022, by a survey method implemented using standardised questionnaires for data collection. The statistical population comprised of 2500 HCWs from 10 hospitals in Kuala Lumpur, Georgetown and Malacca, Malaysia, selected by the simple random sampling among the Muslim staff. The data analysis was further fulfilled using the AMOS software package for structural equation modelling (SEM). In general, the study results demonstrated a significant and positive relationship between RBs and OC among Malaysian HCWs (p-value = 0.84, t-statistic = 6.50).Contribution: As demonstrated by the study results, it is possible to inspire OC among employees through strengthening RBs and take advantages of the results. Thus, RBs shown by employees can definitely bring positive results to organisations; therefore, OC in Malaysian HCWs improves.

Published: February 2023

Tetralogy of Fallot (TOF) presenting with superior vena cava (SVC) syndrome is an exceedingly rare scenario. The diagnosis of this condition is still a difficult task due to its unspecific clinical features and unclear recommendations for the best diagnostic tools. We report an interesting case of a 23-year-old male who was found to have TOF with the presentation of SVC syndrome after a sequential diagnosis. The timely diagnosis helped in the successful management of the patient. Through this case, we want to make clinicians aware of such a rare association and its diagnosis.
Transcatheter Mitral Valve Repair in Acute and Critical Cardiac Conditions
Authors: Kaddoura Rasha , Al-Hijji Mohammed
Published: February 2023

Acute mitral valve regurgitation (MR) is an emergency condition that requires an early diagnosis of the etiology and rapid management. Surgical intervention is the first-line treatment for acute severe MR. However, many patients are denied surgical intervention due to the acute risk of surgery. Transcatheter mitral valve repair (TMVr) is a less invasive technique and becoming a potential alternative to surgery in inoperable patients but is underrepresented in the literature. This review aims to discuss the published data on the use of TMVr in unstable MR patients presenting with acute or critical cardiac conditions.

Published: February 2023

Objectives:

To investigate the relation between serum Vitamin D (Vit-D) levels and the success rate of cardioversion for atrial fibrillation (AF). To examine the association between Vit-D level and successful cardioversion. This study also describes the general characteristics of patients with successful cardioversion.

Materials and Methods:

In this retrospective study, patients with AF who were treated using electrical cardioversion at King Abdulaziz Cardiovascular Center (KACC) between 2010 and 2021 were included. The information on demographic and clinical characteristics as well as outcome variables was collected.

Results:

Of 100 patients who were admitted to KACC during the study period, 63% were females and 9% were diagnosed with Vit-D deficiency. Furthermore, 66% of patients had successful cardioversion. Moreover, no significant difference in Vit-D deficiency was observed between patients who had successful cardioversion and those with unsuccessful outcomes (P = 0.485).

Conclusions:

There is no association between serum Vit-D levels and the success rate of cardioversion in patients with AF. However, further studies are needed for more conclusive evidence.
Comparison of Patent Ductus Arteriosus Stenting and Blalock-Taussig Shunt in Ductal Dependent Blood Flow Congenital Heart Disease and Decreased Pulmonary Blood Flow
Authors: Ghaderian Mehdi , Behdad Samin , Mokhtari Masoume , Salamati Ladan
Published: February 2023

Background:

Congenital ductal-dependent cyanotic congenital heart disease (CHD) is a group of diseases that require early intervention during early infancy or the neonatal period. In this study, we compared the effectiveness, safety, and side effects of stenting patent ductus arteriosus versus a modified Blalock-Taussig (BT) shunt.

Materials and Methods:

Thirty-six neonates and infants with cyanotic CHD who were <6 months old and were not suitable for complete surgery were admitted to Chamran Hospital in Isfahan and enrolled in this prospective longitudinal cross-sectional study. Ductal stenting (DS) was performed in 18 patients and BT shunt in 18 patients. Data were collected and compared in these patients.

Results:

Age, height, and weight were lower in the DS group compared to the shunt group (1.28 ± 0.46 vs. 2.50 ± 0.51 months, 53.22 ± 1.80 vs. 56.11 ± 1.67 cm, 3.38 ± 0.45 vs. 4.98 ± 0.57 kg, respectively P < 0.001). The duration of the intensive care unit stay as well as hospital stay in patients in the DS group was much shorter than the shunt group (1.33 ± 0.68 vs. 2.83 ± 0.70 days, 3.33 ± 0.68 vs. 9.55 ± 0.51, P < 0.001, respectively). In both groups, the diameter of the pulmonary branches increased after the procedure compared to before the procedure (P < 0.001). Furthermore, the patient's hemoglobin was significantly decreased compared to before the procedure (P < 0.001). In both groups, one patient died in the postprocedure period. In ductal stent group one patient died in catheterization lab and in shunt group died 48 hours after surgery. There was no significant difference in postprocedural complications between the two groups.

Conclusion:

Duct stents can be used as an effective and safe method in duct-dependent cyanotic CHD patients who are not suitable candidates for complete surgery. As operators become proficient, this method can be a good alternative to BT shunts with fewer complications.
Recurrent Cardiac Tamponade with Stevens–Johnson's Syndrome – A Rare Deadly Combo
Authors: Tammiraju Iragavarapu , Srinivas B. , Nirupama K. , Naresh K Pruthvi
Published: February 2023

Pericardial effusion is an accumulation of fluid in the pericardial sac. It is caused by exudative or transudative collections. Large effusions can lead to a life-threatening condition called tamponade if not intervened properly. Stevens–Johnson syndrome (SJS) and toxic epidermal necrolysis are life-threatening cutaneous drug reactions in which the epidermis is separated from the dermis. The diagnosis mainly relies on the clinical signs and histopathology of skin lesions. Immunological mechanisms, reactive drug metabolites, or interactions between these two are proposed. Here, we report a case of recurrent cardiac tamponade with SJS secondary to empirical antituberculous therapy.
Challenges in the Implementation of Telemedicine
Authors: Raju P. Krishnam , Sistla Prasad G.
Published: February 2023

Background:

There is a constant search across the globe for optimal healthcare solutions with affordability, accessibility, availability, and quality of healthcare services being the burning issue for mankind. The pandemic has further necessitated the need of use of the Telemedicine platform to address healthcare issues which are also non Covid related. Though Telemedicine has been in use for over two decades in India, there have been various challenges and adoption issues which have not yet made the technology an effective solution to address the current healthcare issues. There has been phenomenal growth in the Information and Communication Technology (ICT) over the last decade and its utilization in the healthcare field.

Methods:

Internet research on the various adoption strategies by healthcare providers coupled with our own experience for using this technology along with guidelines provided by the information and communication technology providers. The Telemedicine Guidelines of 2020 released by the Ministry of Health and Family welfare, India, provides a framework for the implementation of healthcare delivery through this technology.

Results:

This paper mentions our telemedicine experience in governmental and private institutes and highlights the implementation challenges of this technology and some solutions that made a difference in the execution. However, we discuss to a larger extent the possible challenges and barriers in the implementation of this technology in India.

Conclusion:

Despite successful work in the field of telemedicine, it is yet to become an integral part of healthcare system because challenges related to adaptability of healthcare users and lack of proper training to fast growing technologies. The future is going to compel the usage of this kind of technology and it is essential for setting up infrastructure and having trained personnel to man these departments to encash the full potential of the telemedicine technology.

Published: February 2023

Introduction:

Atrioventricular (AV) block is a common problem worldwide requiring permanent pacemaker implantation, which results in a huge economic burden on society. In our country, the major burden is noted in eastern India. The etiopathological correlation of degenerative conduction tissue disorder does o't explain the differential volume of disease. We speculate environmental link, particularly the influence of elevated trace metals in the pathogenesis of this condition.

Purpose:

The purpose of the study was to investigate and correlate the concentration of trace metals in blood of patients who have received a permanent pacemaker.

Materials and Methods:

The blood samples of 81 patients who had permanent pacemaker implantation in the past 3 years were collected and levels of various trace metals were evaluated. It was done using inductively coupled plasma mass spectrometry. The values were expressed in μg/l.

Results:

There were elevated trace metals in 21 patients and 4 among them had an overlap of more than one abnormal values. Strontium (Sr) surprisingly was elevated in a maximum of 11 patients. The most interesting observation was a trend of Sr being elevated in male sex with AV nodal disease.

Conclusion:

From this study we hypothesize, Sr affects ion channels in conduction tissue due to its close chemical similarity to calcium. In long run, it could have been inducing fibrosis causing AV blocks. Our observation suggests that trace metal screening may be considered in areas with a high prevalence of AV blocks requiring permanent pacemakers.

Results: Successful BMV was performed in 72 patients. The rate of complication was 2.7%. No mortality was noted. One hundred and eighty-eight patients underwent Valve replacements.

Conclusions:

Balloon mitral valvuloplasty is a technically difficult procedure and demands considerable expertise in transseptal catheterization. Percutaneous balloon mitral valvotomy is a safe and effective treatment for symptomatic severe Mitral stenosis in experienced centers.
Clinical Potential of Glucagon-like Peptide-1 Analogs in the Management of Diabesity
Authors: Sharma Nidhi , Singh Shreya
Published: February 2023

Obesity and cardiovascular complications are the two pandemic which plays a crucial role in the pathophysiology of type 2 diabetes mellitus. Loss of weight and increased cardiovascular risk are becoming the hurdles for the diabetic population. The tremendous hike in the rate of obesity is one of the main reasons for the increased cases of diabetes mellitus and hence, obesity becomes a high-risk factor for diabetes. Glucagon-like peptide-1 (GLP-1) agonists were initially developed for the treatment of diabetes mellitus but was found to be effective not only for the glycemic control but also for the weight loss. Hence this review article aims to assess the clinical efficacy of GLP-1 agonists in the management of weight loss, and also discusses the detailed insights of FDA approved drugs used in weight management, and discuss the mechanisms by which GLP-1 agonist, used in weight loss therapy. It also discusses the role of dual co-agonist in the treatment of obesity. This literature survey has been done by searching term “GLP-1 agonist, diabetes, obesity, novel drug targets” in the PubMed, Scopus, Embase, and web of science databases. Then, the search is further narrowed by including the articles having recent updates only and then further it is narrowed by excluding the animal studies and including only the clinical studies. This article is purely based on the published clinical data obtained from various clinical trials. Based on the previous studies and clinical trials, it has been observed that GLP-1 agonists such as liraglutide and semaglutide are more efficacious drug than other approved drugs in weight management therapy and have advantage of improving the blood glucose profile and reduces the cardiovascular risk also. It is also found that dual gastric inhibitory polypeptide (GIP)/GLP-1 agonists is regarded as the more effective in treating obesity than the GLP-1 agonist alone.

Authors: Aziz Mohamad Azwan , Hazwan S. Ahmad , Mohamed Nahar Azmi
Published: February 2023

Background:

Lower limb musculoskeletal profiling is important in pre-competition medical assessment (PCMA) as it helps to identify musculoskeletal pathologies that need rehabilitation and risk factors for injury that need specific prevention programme. However, a normative value is needed to identify which is normal or pathological. Our objective in this study is to establish a normative value for football-specific adaptation of lower limb musculoskeletal examination among Malaysian professional footballers.

Materials and Methods:

This is a prospective cross-sectional examining 83 Malaysian footballers from a single club during PCMA from 17 January 2022 to 17 February 2022. We included anthropometric assessments using body impedance analysis, objective lower limb muscle strength assessments using handheld dynamometer, range of motion and objective dynamic balance test using the Biodex system.

Results:

The mean age of our study was 20.3 ± 3 years. Goalkeepers and defenders have a higher body mass index and a higher skeletal muscle mass. Strikers and midfielders have a higher quadriceps and hamstring strength. Non-dominant leg has a better overall stability and anterior posterior stability index compared to dominant leg. Defender has a better overall stability. Sixty-six footballers (80%) have at least 1 low Add: Abd ratio of less than 0.9, which requires preventive programme for groin injury.

Conclusion:

This study demonstrates a position-specific adaptation in different positions in football.

Authors: Hamdan Muhammad , Sharir Raihana , Yeo Wee Kian , Adi Sapto , Amran Mohammad Nor Ashraff , Raja Azidin Raja Mohammed Firhad
Published: February 2023

Background:

Knee injuries are the most common injury among Malaysian elite athletes. However, an injury profile of elite soccer players in Malaysia is yet to be determined.

Aim and Objectives:

This study was conducted to determine the injury characteristics among elite, male U19 and U22 soccer players.

Materials and Methods:

Four teams were observed throughout the 2018/2019 season, where a total of 111 players were documented in accordance with the Federation International de Football Association Medical and Research Centre accord to determine the incidence, class, severity and causation of injuries among elite, male U19 and U22 soccer players.

Results:

From a total of 111 players (U19: n = 58; U22: n = 53) during the 2018–2019 season, a sum of 64 injuries were reported to the team physicians of the participating teams in the current study, representing an estimated 0.58 injuries per player throughout a single season. From the total number of injuries, 57.8% (n = 37) injuries were registered to the U22 age group, whereas 42.2% (n = 27) were reported in the U19 Age Group. When factoring in the number of players in each respective age group, the number of injuries among the U22 age group was higher than the U19 age group (0.72 vs. 0.47 injuries/player/season).

Conclusion:

Most soccer injuries reported were lower limb injuries, newly sustained and required up to 14 days of treatment before returning to full participation in the competition. Match-play injuries appeared to be more common than training injuries, with the ankle and knee joints being the most common injury locations. Sprains and ligamentous damage were the most common injury class sustained by players.
The effect of foam padding on the head response in soccer heading
Authors: Tan Fu Yang , Hassan Mohd Hasnun Arif , Johari Nasrul Hadi , Omar Mohd Nadzeri , Hasanuddin Iskandar
Published: February 2023

Background:

Soccer is regarded as the most popular sports in the world, with millions of people are actively involved in the game. Being a contact sports in nature, soccer players are susceptible to various kinds of injuries such as lower extremities muscle injury. In addition to those familiar injuries that soccer players sustain during the game, traumatic brain injury is also a possibility. Head impacts in soccer could be a result of head-to-head impact with an opponent player, head-to-elbow impact, an impact with the goal post, impact with the ground, as well as an impact with the soccer ball, which occurs during a heading manoeuvre. Soccer allows the players to use their head to hit the ball to pass it to a teammate, or even perform heading to score goal. Although soccer heading is perceived as less harmful as compared to head impacts with other hard objects, many studies have shown compelling evidence that this repetitive heading might harm the brain, thereby leading to traumatic brain injury. Protective headgears designed, especially for soccer players have been commercially available in the market for some years.

Objective:

This article investigates the effectiveness of two padding foams by means of heading experiment.

Methodology:

An anthropometric test device known as Hybrid III head and neck dummy instrumented with an inertial sensor that consists of a triaxial accelerometer and gyroscope installed at the centre of gravity of the head was used in the experiment. A soccer ball launching machine was used to propel the ball at several inbound velocities. Peak linear acceleration and peak rotational acceleration (PRA) were recorded, and the head injury criterion (HIC) and the rotational injury criterion (RIC) were calculated.

Results:

Poron X-ray diffraction (XRD) foam was found to provide the best protection in both linear and rotational components. However, for protection against HIC, it is evident from the findings that both foams were very effective at lower inbound ball velocity and became drastically ineffective as the inbound velocity increases up to 22 m/s (i.e. equal to 79.2 km/h). This could be attributed to the foam being completely compressed by the high-velocity ball impacting it. The same situation is seen for RIC, however with less significant decline in protective performance.

Conclusion:

Overall, it can be concluded that the Poron XRD foam could be a better foam to be used in soccer headgear as compared to the yoga mat foam.

As the world faces a climate crisis and ozone depletion, it is essential to turn
our attention to renewable energy sources. Fossil fuels used in the automobile
and aviation industry generate huge amounts of air pollution damaging the
environment. Pollution generated by this industry contributes to 2.1% of all
human-induced carbon dioxide emissions. Renewable energy usage has surged in the
last five years to a great extent. Solar energy is one of the most widely used
and available sources of energy. Solar photovoltaics accounted for 3.6% of
global electricity generation, and it remains the third largest renewable
electricity technology behind hydropower and wind. To generate energy through
solar, solar panels are used. But the problem with solar panels is that their
efficiency is low and a large number of panels are required which take up a huge
amount of space on land. The area of land used for solar goes to waste. Hence,
this paper aims to solve the problem by developing a solar-powered aircraft to
generate energy using solar. We designed different radio-controlled (RC)
aircraft models and analyzed the performance of the aircraft using solar sheets,
solar panels, and solar cells on the model. We calculated the energy/power
required to power the aircraft and which configuration provides the best
results.
Baxter, Ivy (1923–1993)
Authors: Sörgel Sabine

In the years pre-dating Jamaican independence, Ivy Baxter pioneered a new approach towards dance theatre as a community art form. Along with Beryl McBurnie and Lavinia Williams, she was known as one of the leading figures of Caribbean dance, pioneering what was called bare foot movement in the 1950s. Dissatisfied with the teachings of Eurocentric ballet, Baxter was the first Jamaican dance choreographer to explore the island’s diverse Africanist folk forms and to blend and integrate folk forms with modern expressionist dance of the Sigurd Leeder and Rudolf Laban school. As the founder of Ivy Baxter Dance Group in 1950, she became part of the national independence movement reformulating an African Jamaican national identity by celebrating African cultural roots and traditions. Her dance theatre included narrative elements that dramatized local customs and daily life and used live drumming and local music accompaniment by the Frats Quintet (an all-male group of local singers). Among the early members of her company were such dancers and choreographers as Rex Nettleford, Clive Thompson, and Garth Fagan. Her book The Arts of an Island (1970) was among the first written accounts of Jamaican dance forms and influenced many dancers and choreographers who followed her lead.
Reed, John (1887–1920)
Authors: McGowan Patrick
Published: February 2023

Born in Portland, Oregon in 1887, John Reed was a radical American journalist known for his depictions of early twentieth-century labour politics and political revolutions. Reed’s influential works include Insurgent Mexico (1914), an impressionistic account of the Mexican Revolution which draws upon Reed’s experiences as a reporter embedded with revolutionary general Pancho Villa, and Ten Days That Shook the World (1919), a firsthand portrait of Russia’s Bolshevik Revolution of 1917. Both books, like Reed’s shorter pieces published in The Masses and The Metropolitan, utilized objective reporting, first person perspective, and literary embellishment.
Kaléko, Mascha (1907–1975)
Authors: Howard Christian
Published: February 2023

Mascha Kaléko was a transnational Jewish German-language poet and one of the few female representatives of the New Objectivity (Neue Sachlichkeit). Her early works include Das lyrische Stenogrammheft (‘The Lyrical Notebook in Shorthand. Poems of the Everyday’; 1933) and Kleines Lesebuch für Große (Little Reading Book for Big People; 1934), both of which were blacklisted by the Nazis in 1937. After fleeing with her family to New York in 1938, Kaléko continued to publish her poetry in German. Although she received the Fontane Prize in 1960, Kaléko refused to accept the award because it was to be handed over by a former Nazi official.
Lugones, Leopoldo (1874–1938)
Authors: Wells Sarah Ann
Published: February 2023

The author of short stories, novels, essays, and journalism, Leopoldo Lugones is best known as Argentina’s most famous modernista writer, with several volumes of influential and highly varied poetry that ultimately led to an exhaustion of modernista verse. His other major contributions to Argentine literature include to the genre of fantastic fiction and his essays on Argentine identity and literary history. In the latter, he located the marginalized figure of the gaucho as a romantic origin for a national culture. Lugones’ legacy has been marked by the increasingly nationalist-fascist bent of his poetry and essays, beginning in the 1920s. However, the legacy of his earlier, audacious poetic experiments on the future poetic movements of the avant-gardes persist.

Jan Rabie was a key figure in the movement in Afrikaans literature known as the Sestigers, comprising writers who published in the 1960s. Living in Paris for a number of years (1948–55), Rabie played an important role in the lives of several prominent Afrikaans writers who went to Europe and for whom he became a role model. He was married to Marjorie Wallace, a well-known South African painter of Scottish descent. From 1970 they lived in the small coastal village of Onrus in the Western Cape, and their home became a famous meeting place for artists and writers.
Rive, Richard Moore (1931–1989)
Authors: Hall Molly
Published: February 2023

Born 1 March 1931 in Cape Town, South African author Richard Rive was a novelist, editor, short story writer, and critic. Rive grew up in a ‘coloured’ working-class area of Cape Town called District Six, a segregated area he later wrote about in his widely acclaimed novel, ‘Buckingham Palace’, District Six (1986). Rive himself was ‘coloured’, which in South African lexicon refers to a specific interracial identity particular to the area and distinct from Black Africans, considered to be a sort of creolisation of various African, white, and indigenous ethnicities. His father, an African-American ship-hand named Richardson Moore, left him and his ‘coloured’ mother a few months after his birth, never to be seen again.
Senghor, Léopold Sédar (1906–2001)
Authors: Benga Ndiouga
Published: February 2023

Poet, politician, and cultural theorist, Léopold Sédar Senghor was the first president of Senegal from 1960 to 1980. His devotion to the arts as a critic, aesthete, and patron developed during the inter-war period in the formation of the concept of Négritude along with Aimé Césaire and Léon Damas. Senghor designed and built everything, according to the understanding of Négritude as African authenticity independent from Western art conventions, as a claim of black identity and the cornerstones of which are rootedness and openness, which inspire his aesthetic. He proposed an effort to prospective thinking, guided by the movement. The aim was to transmit to young generations the values of Négritude, through the introduction of modern technology. ‘The Priority of Development should not detract from the Primacy of Culture, as a contribution to the Civilization of the Universal which is an integral humanism, a horizon and a purpose, which nurtures and develops both body and soul’ he wrote. It was in the very essence of the policy of Senegal to defend the values of black civilisation and to be the spearhead of young African States in terms of education, culture, and training. Therefore Senghor spent more than 30 per cent of the national budget on these sectors in the 1960s.
Shamir, Moshe (1921–2004)
Authors: Ginsburg Shai
Published: February 2023

A leading Israeli Hebrew author, playwright, essayist, opinion journalist, and editor. He started his literary career as a committed socialist Zionist. Yet he shifted ever more to the right, and in the aftermath of the 1967 Israeli–Arab War he became one of the leading spokespersons for the Israeli nationalist right, serving as a member of the Israeli parliament between 1977 and 1981 as a representative of that sector. This political transition was also reflected in his fiction. Shamir is widely recognised, alongside S. Yizhar, as the most prominent writer of what is generally known as the ‘1948 Generation’.
Turina, Joaquín (1882–1949)
Authors: Payne Alyson
Published: February 2023

Joaquín Turina (b. Seville, 9 December 1882; d. Madrid, 14 January 1949) was a Spanish composer who rose to prominence during Spain’s Edad de Plata (1900–36), also referred to as the Silver Age, a time when Spain’s artistic development increased rapidly. Along with Manuel de Falla, Joaquín Rodrigo, and Conrado del Campo, Turina became of one the leading Spanish composers of his generation.

Turina enjoyed a middle-class upbringing in an artistic household—his father was a well-regarded and well-known Spanish painter. Turina displayed an early aptitude for music, spending extensive time practising an accordion given to him by the family’s servant. Turina later received piano lessons from the composer Enrique Rodríguez. Turina demonstrated a propensity for the piano, and he continued his musical studies with lessons in contrast and harmony to the choirmaster of Seville cathedral, Evaristo García Torres. Turina gave his first public performance on 14 May 1897, playing Thalberg’s Fantasy on Moïse, a piece demanding technical prowess. The performance was a success, and informed Turina’s decision to study music in Madrid with José Tragó (who taught the young Manuel de Falla), where he studied from 1902 to 1905.
Lowry, Laurence Stephen (1887–1976)
Authors: Little Helen
Published: February 2023

L. S. Lowry was a modern British artist celebrated for his depictions of Salford and Manchester. As well as making portraits, landscapes, and seascapes, he is best known for painting what the artist called ‘the industrial scene’, by which he meant the physical fabric of Britain’s industrial north, its distinctive sense of place and accompanying phenomenon of working-class culture. Often populated with crowds of people set amidst a backdrop of terraced streets, mills, and factories, Lowry’s urban scenes speak to the region’s identity as pioneer of the Industrial Revolution as well as the radical social, economic, and environmental upheaval of the early twentieth century.
O’Gorman, Juan (1905–1982)
Authors: Santoyo-Orozco Ivonne
Published: February 2023

Perhaps the best way to understand the Mexican architect and painter Juan O’Gorman is through his self-portrait of 1950 in which he depicts himself in multiple frames corresponding to his different occupations. Juan O’Gorman was born in Mexico City of Irish descent. He graduated in 1927 from the School of Architecture of the National Autonomous University of Mexico and began his career working as a draughtsman in the studio of Obregón, Tarditi, and Villagrán García (1921–5), and, later on, as an architect for Carlos Obregón Santacilla (1925–8). At a very early age, O’Gorman designed the first functionalist houses in Mexico (1929), the most representative of this being the House-Studio of Diego Rivera (1931). For him, functionalism was to be understood as the tendency to design architecture as a work of engineering, which he understood as maximum efficiency and minimum maintenance. However, in time his designs moved towards an organic formalism influenced by the work of Frank Lloyd Wright, Antonio Gaudí, and Ferdinand Cheval, exemplified most explicitly in his house-studio in San Jeronimo (1951). Around the same time, he also designed the Central Library of the National Autonomous University Campus in the south of Mexico City, a piece that can be considered representative of O’Gorman’s various aesthetic interests: an efficiently organised slab, whose massive 4,000-sqm facade is a continuous stone and glass mosaic expressing a political and social history of Mexico.
Shahn, Ben (1898–1969)
Authors: Porter Austin
Published: February 2023

Ben Shahn was an American painter, photographer, muralist, and graphic artist. His realist style, left-wing political activism, and socially conscious artwork exemplify social realism. After immigrating to Brooklyn from Lithuania in 1906, Shahn trained as a lithographer. He received early critical success with The Passion of Sacco and Vanzetti (1931–2), a series of paintings that addressed the controversial trial of two Italian anarchists. During the Great Depression’s economic instability, Shahn created posters, murals, and photographs for New Deal agencies promoting government aid. His post-war work included paintings with symbolic themes drawn from his Jewish heritage, and commercial projects exhibiting expressive typography.
