Published: July 2023

The global temperatures have shown the tendency of global warming and climate change continues, that is why, the need is to search alternatives that are effective in the thermic reinforcement of the envelope of the dwelling. In consequence, the objective of the present investigation was to analyze the thermal behavior of a material that promises thermal lag qualities effective in comparison to the traditional finishes. This text was worked under a monitoring scheme and analysis of the results through a unit difference. The results indicate that the material of finishes studied favors the thermal lag between superficial temperatures and stability in thermal oscillation from the interior side of the wall and the roof analized. This article works as a divulgation and invitation to other investigations that share the objective to analyze materials that favor the thermal lag and energetic efficiency in the envelopes of the buildings.
SCAD model of solid finite elements: calculation of reinforced concrete waffle slabs
Authors: Mozgolov M. V. , Kozlova E. V.
Published: July 2023

Introduction. Current requirements for structural engineering oblige designers to use structures capable of resisting progressive collapse. Such structures include multiribbed reinforced concrete waffle slabs. Spatial systems are multiple indeterminate, their calculation is carried out in software systems based on the finite element method. Models of ribbed structures can be developed from different types of finite elements. The forces determined by different models can vary significantly, which is confirmed by the examples available in the literature.

Aim. To detect a simple and accurate finite element model for computer-aided calculating the ribbed reinforced concrete waffle slab.

Materials and methods. The study was carried out by comparing the bending moments obtained analytically and in the SCAD software by the finite element method for beams in waffle slabs of 12.0 × 18.0 m in plan with caissons of 1.5 × 2.25 m. The bar model consisting of a T-beam-and-girder construction and a solid model of bulk finite elements are calculated.

Results. The bending moments, calculated both analytically and using a solid model, have similar values. The maximum deviations of the computer calculation from the analytical method are from -3.2 to +2.6 %. The maximum deviations of the values of bending moments obtained when comparing the solid model with the bar model are from -9.2 to +4.0 %.

Conclusion. The finite element model, which is based on solving the volumetric problem of the elastic theory, is an effective verification model for studying complex systems; however, it is time-consuming and difficult for data analysis. A solid model can be recommended for studying individual structures or their critical zones.
Detection and localization of multi-scale and oriented objects using an enhanced feature refinement algorithm
Authors: Johnson Deepika Roselind , Vaidhyanathan Rhymend Uthariaraj
Published: July 2023

Object detection is a fundamental aspect of computer vision, with numerous generic object detectors proposed by various researchers. The proposed work presents a novel single-stage rotation detector that can detect oriented and multi-scale objects accurately from diverse scenarios. This detector addresses the challenges faced by current rotation detectors, such as the detection of arbitrary orientations, objects that are densely arranged, and the issue of loss discontinuity. First, the detector also adopts a progressive regression form (coarse-to-fine-grained approach) that uses both horizontal anchors (speed and higher recall) and rotating anchors (oriented objects) in cluttered backgrounds. Second, the proposed detector includes a feature refinement module that helps minimize the problems related to feature angulation and reduces the number of bounding boxes generated. Finally, to address the issue of loss discontinuity, the proposed detector utilizes a newly formulated adjustable loss function that can be extended to both single-stage and two-stage detectors. The proposed detector shows outstanding performance on benchmark datasets and significantly outperforms other state-of-the-art methods in terms of speed and accuracy.
Intention, sensation et mémoire dans l’esthétique médiévale
Authors: Carruthers Mary
Published: July 2023

La présente étude insiste sur trois aspects de l’expérience sensorielle telle que les penseurs médiévaux l’ont entendue. Premièrement, toute perception ou expérience sensorielle implique des désirs orientés, appelés intentiones ou voluntates dans la terminologie augustinienne ; ce sont les mouvements naturels de l’âme, non des « états » psychiques, mais bien plutôt des énergies dirigées vers un objectif. En second lieu, les êtres humains pensent essentiellement au moyen d’images mentales formées à partir des données sensorielles brutes par un processus psychologique spécifique aboutissant à leur stockage dans la mémoire sous une forme qui permet leur mobilisation ultérieure au moyen du souvenir, processus associatif rationnel. En troisième lieu, toute sensation est un assemblage complexe de qualités et d’éléments, à l’instar d’ailleurs de tout être naturel. Aucune n’est pure ou singulière, et, partant, aucune de nos expériences esthétiques n’est pure et singulière. En concentrant mon propos sur l’analyse de l’intentio telle qu’on la trouve dans le livre xi du De Trinitate de saint Augustin et dans une psychologie des images mentales et du souvenir dérivée d’Avicenne et de Thomas d’Aquin, je m’attache à démontrer comment ces principes sont liés aux cinq sens à partir desquels sont créées les expériences humaines naturelles.
Gut microbial regulation of innate and adaptive immunity after traumatic brain injury
Authors: Celorrio Marta , Shumilov Kirill , Friess Stuart H.
Published: July 2023

Acute care management of traumatic brain injury is focused on the prevention and reduction of secondary insults such as hypotension, hypoxia, intracranial hypertension, and detrimental inflammation. However, the imperative to balance multiple clinical concerns simultaneously often results in therapeutic strategies targeted to address one clinical concern causing unintended effects in other remote organ systems. Recently the bidirectional communication between the gastrointestinal tract and the brain has been shown to influence both the central nervous system and gastrointestinal tract homeostasis in health and disease. A critical component of this axis is the microorganisms of the gut known as the gut microbiome. Changes in gut microbial populations in the setting of central nervous system disease, including traumatic brain injury, have been reported in both humans and experimental animal models and can be further disrupted by off-target effects of patient care. In this review article, we will explore the important role gut microbial populations play in regulating brain-resident and peripheral immune cell responses after traumatic brain injury. We will discuss the role of bacterial metabolites in gut microbial regulation of neuroinflammation and their potential as an avenue for therapeutic intervention in the setting of traumatic brain injury.
A sweet emergency due to bitter poisoning—A case report
Authors: Joseph Jenny , Thangavelu Saravanan , Shanjitha J , Jacob Deepak
Published: July 2023

ABSTRACT

Organophosphorus compounds (OPC) are major components of pesticides and nerve gas agents. Self-harm by ingestion of OPC pesticides is one of the common problems encountered in the emergency room (ER), especially in developing countries such as India. It is recognised by the World Health Organization (WHO) as the third most prevalent means of suicide. In addition to the cholinergic effects caused by these agents, they can induce metabolic dysregulations. We present a case of a 22-year-old male patient, without previous history of diabetes, who was brought to the ER in an unresponsive state with an HbA1c of 5%. His initial laboratory investigations revealed hyperglycemia, high anion gap metabolic acidosis, ketonuria, and glycosuria. His relatives revealed intentional ingestion of OPC. He was treated for both OPC poisoning and hyperglycemic ketoacidosis. Adequate acute care was instigated though prognosis could not be gauged due to the early discharge of the patient against medical advice. This case highlights that OPC poisoning can be a possible etiological factor for hyperglycemic ketoacidosis. It can mimic diabetic ketoacidosis leading to delayed diagnosis. Thus, early identification and immediate management are crucial because of the effect of hyperglycemic ketoacidosis on the outcome of a patient with OPC poisoning.
Assessment of available health services at subcentres as per Indian public health standards guidelines in a district of Jammu and Kashmir India: A cross sectional study
Authors: Kataria Ghulam Mustafa , Kaul Rauf Ur Rashid
Published: July 2023

ABSTRACT

Background:

Subcentre is the lowest rung of a referral pyramid of health facilities. The purpose of health subcentre is mainly providing preventive and promotive services, but it also provides a basic level of curative services.

Objectives:

To assess the existing services availability at subcentres and identification of gaps between minimum requirements as per Indian public health standards and actual availability of services at subcentres.

Material and Methods:

It was a cross sectional observational study. Study units were subcentres. Fifty percent of subcentres of the district were selected using simple random sampling method. Check list prepared from Indian public health standards facility survey formats was used for data collection and collected data were analysed using statistical package for social sciences.

Results:

Majority (58.8%) of the subcentres were catering a population in the range of 1000–3000. Ante-natal and child care related services were available in all subcentres. Intra-natal services were available in only two subcentres. Eighty five percent of subcentres were involved in providing school health related services.

Conclusion:

Most of the services as recommended by Indian public health standards were available in the studied subcentres. The lack of some services was mainly due to inadequate staff and infrastructure at subcentres. Comprehensive efforts are required to ensure adequate service delivery at all health centres.

Published: July 2023

Objective

This study was planned to compare the distraction of the lesser segment versus the greater segment via usage of (Liou cleft distractor) in repair of unilateral alveolar cleft.

Patients & Methods

16 patients with unilateral alveolar clefts were included in this study. They were divided into two equal groups according to the osteotomized segment, Group I: in which the lesser bone segment was osteotomized for alveolar cleft repair. Group II: in which the greater segment was osteotomized for alveolar cleft repair.

Results

Stage I distraction: after three months, showed significant difference in the width of the cleft side in both groups as P-value was 0.007 in group I and P-value was 0.001 in group II. No significant differences in the vitality and mobility of teeth in both groups. The amount of relapse in the regenerate area at the different observation periods 3 and 6 months between both groups were statistically significant (P-value 0.018). Radiographic finding showed no significant difference of the inclination changes of the transported segment in group I (P-value 0.816), while in group II showed significant difference (P-value 0.001). Stage II alveolar cleft grafting: graft resorption and recurrence of fistula was recorded in one case of group II. The differences of the density of the grafted bone between the first month and six months in each group postoperatively were statistically significant in both groups as P-value 0.001 and 0.001 in group I and Group II respectively.

Conclusion

Both the lesser and the greater segments are suitable for treatment of alveolar cleft with some drawbacks related to the palatal inclination of transported segment in group II as compared to group I.

Published: July 2023

Statement of the problem

For permanent molars in young age, which treatment planning guarantees better performance of such weakened teeth should be followed starting from the endodontic therapy till the final coronal restoration?

Purpose

The aim was to evaluate the performance of endocrowns as permanent restorations for endodontically treated molars (ETMs) in young age in a 2-year period.

Materials and methods

Inclusion and exclusion criteria were established. Ten patients of 9–12 years old were selected at random, in accordance with Research Ethics Committee (REC) of Faculty of Dental Medicine for Girls, Al-Azhar University and in conjunction with Departments of Pedodontics, Endodontics, and Crowns and Bridges. For endodontic treatment, Protaper Next system and iRoot SP sealer were used. According to the coronal restoration type, the patients were divided into two groups. Group 1: the patient received direct composite resin restorations, and Group 2: the patient received endocrown restorations. Due to the small sample size, statistical descriptive methods were applied.

Results

After 2-year follow up, all endocrowns were in function while two composite restorations failed.

Conclusions

In young age, ETMs restored with Protaper Next system, iRoot SP sealer, and IPS e.max CAD endocrowns have excellent clinical performance.

Clinical significance

In young age, whenever indicated, endocrowns are highly recommended for ETMs as permanent, esthetic and conservative type of restorations.
Ensamble de memorias.

Published: July 2023

En este artículo me interesa concentrar el análisis en diversas acciones de memorias producidas desde abajo, en el contexto latinoamericano. A partir de pequeños gestos y acciones, centradas en los objetos que casi milagrosamente han revelado el poder de la materialización para sostener el recuerdo. En las luchas que mujeres y hombres han entablado para tornar visibles a sus muertos y desaparecidos a partir de la ocupación del espacio público. Los procesos de memorias constituyen, en esta mirada, actos de insurgencia y prácticas de resistencia, producidas en un flujo continuo en el tiempo, lo que las hace dinámicas y cambiantes; incómodas y creativas en tanto dejan nuevas marcas sobre los modelos de los emprendimientos oficiales.
«Él dio su vida por nosotros»
Authors: Figueroa Espejo Mercedes
Published: July 2023

La Comisión de la Verdad y Reconciliación del Perú (2003) concluyó que las fuerzas estatales fueron  responsables de aproximadamente un tercio de las víctimas mortales y más del 60 % de las desapariciones forzadas, durante el conflicto armado interno (1980-2000), enfrentando hoy graves denuncias por violaciones a los derechos humanos. Por esto, entre otros motivos, son percibidos como «perpetradores» y sus familiares constituyen un grupo escasamente visibilizado en las discusiones sobre el pasado reciente y políticas de reparación. Este artículo surge de mi investigación doctoral, desde la cual me pregunto por el lugar de las memorias familiares en las disputas por la verdad sobre el conflicto armado interno. Para responder a ello, desde una metodología participativa y una etnografía remota, me acerco a las fotografías familiares de policías y militares fallecidos desde los recuerdos de sus familiares más cercanas como una manera de visibilizar otras experiencias sobre la violencia de esos años. Particularmente, en este artículo reflexiono sobre cómo la  presencia (visual y discursiva) del uniforme en el ámbito doméstico, enmarcada en una variedad de prácticas fotográficas, da cuenta de una serie de negociaciones entre narrativas institucionales y familiares sobre el pasado violento.
Tras las desapariciones forzadas: reunificando familias, develando memorias
Authors: Garay Doig Carolina
Published: July 2023

Este artículo aborda las experiencias de reencuentro familiar de un grupo de seis niños(as) que perdieron el rastro de sus seres queridos y lugares de origen a causa del conflicto armado en el Perú (1980-2000). Por más de veinte años, las familias de estos menores los dieron por muertos y desaparecidos. Al profundizar en sus historias de vida, se observa que el reencuentro familiar, lejos de constituirse en un «final feliz», es una experiencia sensible y difícil, llena de matices y hasta conflictiva. El reencuentro con los «seres queridos» se constituye en un desafío familiar que cuestiona la propia noción de familia. Implica involucrarse en un proceso de develación de memorias dolorosas y traumáticas. En ese sentido, las memorias y las prácticas familiares cobran un rol crucial al momento de «hacer familia» otra vez y, en especial, en la reconstrucción de los lazos y afectos de familias quebradas, dañadas y desplazadas.

Satellite (GOSAT-2 CAI-2) retrieval and surface (ARFINET) observations of aerosol black carbon over India
Authors: Gogoi Mukunda M. , Babu S. Suresh , Imasu Ryoichi , Hashimoto Makiko
Published: July 2023

Abstract. Light-absorbing black carbon (BC) aerosols strongly
affect Earth's radiation budget and climate. This paper presents
satellite retrieval of BC over India based on observations from the Cloud
and Aerosol Imager-2 (CAI-2) on board the Greenhouse gases Observing
Satellite-2 (GOSAT-2). To evaluate and validate the satellite retrievals,
near-surface BC mass concentrations measured across the Aerosol Radiative
Forcing over India NETwork (ARFINET) of aerosol observatories are used. Then
the findings are extended to elucidate global BC features. The analysis
reveals that this satellite retrieval clearly demonstrates the regional and
seasonal features of BC over the Indian region, similarly to those recorded
by surface observations. Validation and closure studies between the two
datasets show RMSE < 1 and absolute difference below 2 µg m−3 for > 60 % of simultaneous observations, exhibiting
good associations for December, January, and February (R of approximately
0.73) and March, April, and May (R approx. 0.76). Over the hotspot regions
of India, satellite retrievals show a soot volume fraction of approx. 5 %,
columnar single-scattering albedo of approx. 0.8, and BC column optical
depth of approx. 0.1 during times of the highest BC loading, which are
comparable to other in situ and satellite measurements. In terms of global
spatiotemporal variation, satellite retrievals show higher BC occurring
mostly in areas where biomass burning is intense. Overall, this study
highlights the effectiveness of satellite retrieval of BC, which can be used
effectively for the regular monitoring of BC loading attributable to
vehicular, industrial, or biomass burning activities.

Published: July 2023

This study presented the impact of pH and octenyl succinic anhydride (OSA) concentration on the esterification reaction of heat-moisture-treated sago starch (HMT-S) using response surface methodology to achieve optimum degree of substitution (DS), reaction efficiency (RE), and water contact angle (CA). The results showed that HMT-OSA sago starch (HMT-OS) starch exhibited an optimum pH of 7.26 and an OSA concentration of 4.53%. The DS value, RE, and water CA of optimized HMT-OS starch were 0.0121, 33.07%, and 90.11°, respectively. Furthermore, the optimized HMT-OS was used to evaluate the effect of starch modification on film characteristics. HMT-OS film has the best moisture-proof and mechanical properties compared to control (NS), HMT-S, and N-OS films, as indicated by lower water vapor permeability (28.69 g H2O.mm/s.m2.Pa × 10-11), water solubility (26.61%), higher CA (104.40°), elongation at break (85.63%), and transparency (3.25% mm-1). According to the scanning electron micrographic images, the absence of cracks or pores was attributed to the waterproof properties and flexibility of the film. Conversely, x-ray diffraction results showed that the crystallinity of HMT-OS film decreased to 36.05%.

Authors: Faizan Asad  , Faiza Fiaz  , Amna Sheraz  , Ayesha Nabi Ahmed  , Irfan Javaid  , Talib Hussain
Published: July 2023

Objective: Metformin hydrochloride possesses a shorter sort of biological half-life of 1.5–1.6 h with having the absolute type of bioavailability that ranges between 50-60%, the moment it is administered orally. Reduced GIT disturbances and low bioavailability can be optimized by developing microencapsulation of metformin that could prove beneficial. Method: Paraffin oil had been used in obtaining specific types of primary emulsions, whereas the material that was used in the coating of microencapsulation had been identified as sodium alginate. In the process of complex coacervation, a substance known as Tween 20 was used as a surfactant in enhancing the stability of W/O/W double emulsion. Five different formulations with different concentrations of sodium alginate were tested. Result: Metformin's microencapsulation inside certain types of optimized atmosphere tends to ensure the specific size of 1 μm of microcapsules in a combined form, and encapsulation efficiency reaches up to 84%. FTIR measurements have been used to determine the interaction between drug and polymer. The qualitative analysis result from FTIR ensures that the quality and effectiveness of the drug have been preserved. A calibration curve was used to estimate drug conc. from dissolution samples and kinetic analysis demonstrated anomalous release pattern. The test for drug content yielded ˃95% of concentration. Conclusion: Results extracted tend to tell us that specific complex coacervation that is using sodium alginate in wall material was a viable method that is used in the microencapsulation process of metformin hydrochloride.

Published: July 2023

‘A Study of the Mechanical Properties and Composition of Some HYS 12 Concrete Reinforcement Steel Rods Produced in Nigeria’ has been carried out. The work started with the collection of samples from four different mini mills in Nigeria. These samples were prepared into standard test specimens for the various tests according to the standard specifications for those tests, which included hardness test, impact strength test, tensile test and chemical composition test using Spectro-lab metal analyzer (Fe-01-F). From the results obtained; the study has shown that the value of the mechanical properties that were investigated, which included; hardness, impact strength, yield strength, ultimate tensile strength, and % elongation at failure were all determined by their chemical compositions; particularly, carbon, silicon, and phosphorus. Specimen G4 has the highest mechanical properties of all the mechanical properties tested. It has a hardness value of 34.4BHN, impact strength of 275.0J, yield strength of 526.13 N/mm2, and ultimate tensile strength of 610.01N/mm2. Specimen F3 has the highest % elongation at failure of 15.67%. Specimen A1 has the least % elongation at failure of 8.57%. The higher the value of the strain hardening rate the better for HYS 12 concrete reinforcement steel rods, since this will allow sufficient time for occupants of the building to escape before final failure. In conclusion the work has clearly shown that the mechanical properties of the HYS 12 rolled steel rods studied were dictated by the size, amount, and distribution of the Carbon / cementite phase and on the structure of the metal matrix. This in turn depended on the chemical composition of the specimens, in particular their carbon and Silicon content, and also on processing variables such as method of melting, inoculation practice and the cooling rate of the rolled steel bars. The three constituents of steel, which most affect strength and hardness, they are; total carbon, silicon, and phosphorus.

Abstract. Selan YN, Wihadmadyatami H, Haryanto A, Kusindarta DL. 2023. The tongue morphology of Pteropus vampyrus from Timor Island, Indonesia: New insights from scanning electron and light microscopic studies. Biodiversitas 24: 3512-3518. The large flying fox (Pteropus vampyrus Linnaeus, 1758) is a Southeast Asian megabat species includes with frugivorous bats. The tongue plays a pivotal role in taking, chewing, and swallowing food. The structure of the bat tongue hampers considerable variation, mainly in the papilla. Variations occur owing to the feeding habits, environment, and adaptation of bats to their environments. The aim of this study was to clarify the morphological structure of the tongue of P. vampyrus obtained from the island of Timor, East Nusa Tenggara, Indonesia, by using Scanning Electron Microscope (SEM) and Light Microscopy(LM). This study included six adult bats regardless of sex. Macroscopically, the tongue of P. vampyrus consists of three parts: the apex, corpus, and radix. SEM and LM confirmed that the apex presents filiform papillae of several subtypes, including scale-like filiform, giant trifid, and small crown-like papillae. In addition, the apex features fungiform and transitional papillae between the giant trifid and small crown-like papillae. Furthermore, the corpus consists of filiform papillae (leaf-like filiform and large crown-like papillae) and fungiform papillae. The radix consists of filiform papillae (long conical, leaf-like filiform, and short conical papillae), fungiform papillae, and three V-shaped circumvallate papillae pointing to the larynx.

The influence of technology on the media is not a new phenomenon. Several innovations occurred in print production throughout the years and allowed newspapers to improve their design and visual storytelling, following the idea that sight is our dominant sense. This also applied to the digital world: broadband networks made it possible to upload and download large image files, enhancing the importance of visual content. The advent of user-generated content encouraged professional journalists to try harder to create and deliver material of the highest possible journalistic, aesthetic and technical standard. By the end of the first decade of the 21st century, the use of photography, video, audio and data visualisation on the web had come together into something genuinely new - the form of digital storytelling known as “multimedia”. The increasing dominance of social media, and especially social video, has affected media organisations profoundly. Publishers and broadcasters have become reliant on social traffic, and many find that their visual content is increasingly being accessed outside their own domain. We should also be aware of the forces pulling in a different direction — also towards visuals, but in the truncated, shallow and trivialised form that succeeds on social media. The future of serious journalism is facing numerous challenges.
Der Stürmer in the work of Randall Bytwerk and the evolution of the german press
Authors: Maia Martins Pedro
Published: July 2023

Der Stürmer was the most famous of all the newspapers connected to the National-Socialist Party. With its frequent use of image and its resorting to scandalous and antisemitic themes, this periodical evolved from a weekly regional paper to one of the most popular newspapers in the entire German territory. However, its characterization cannot be reduced to its anti-Jewish content and its graphic component. By using the work of many authors about that newspaper and Nazi propaganda, it is also possible to frame Der Stürmer as part of the general trends of the German press in the beginning of the Twentieth century, and as part of the propaganda system of Nazi Germany, albeit as a suis generis example.

Published: July 2023

A disszertáció célja, hogy fertőzô betegségek terjedésének dinamikáját leíró matematikai modelleket állítson fel, valamint e modellek matematikai analízisét végezze el. Először az SIS járványterjedési modelleket tekintjük át, a legegyszerübbtől kezdve az általánosított és továbbfejlesztett konstrukciókig. Majd, egy több fertőző szakaszból álló SI_1 I_2…I_n S modellt vizsgálunk. Fỏ eredményünk, hogy ha a fertőző I osztályt n=1,2 vagy 3 szakaszra osztjuk, a paraméterek választásától függetlenül az endemikus egyensúly mindig stabil, amikor létezik. Viszont, n≥4 fertôző szakasz esetén minden n-re választhatók a paraméterek úgy, hogy az endemikus egyensúly stabil legyen, de ugyanolyan n-re létezik olyan paraméterválasztás is, hogy az endemikus egyensúly instabil legyen. Ezután a COVID-19 indikátortünet-alapú tesztelésének hatásait vizsgáljuk. A k tesztelési ráta növelésének elônyeit mutatjuk be. Az indikátortünet megfelelô megválasztása is nagy jelentőséggel bír, megmutatjuk, hogy ehhez nem csak a p prevalenciát kell figyelembe venni, hanem az ún. másodlagos tünetesek csoportjának méretét és szezonalitását. Szimulációink megmutatják, hogy az indikátortünet-alapú tesztelés önmagában nem alkalmas egy járványkitörés megelôzésére, pusztán a járvány csúcsának mérsékelt késleltetésére és a terjedés csillapítására. Végül, tömeges tesztelési eljárások modellezését mutatjuk be. Kétféle ún. pooling teszteléssel is foglalkozunk, bemutatjuk e tesztelés reguláris, illetve Dorfman-féle variációját. Megmutatjuk, hogy Dorfman-féle tesztelésnél, optimalizált csoportméretet választva, jelentős számú megbetegedést és elhalálozást akadályozhatunk meg. Továbbá rámutatunk, hogy adaptív módszerrel, a prevalenciától függő̉, optimalizált csoportméretet használva a járvány terjedése még jobban csillapítható.

Ana Laura Godinho Lima e Valéria Cazetta, ao organizarem o livro O Ambiente escolar em transformação, publicado pela Editora Alínea, oferecem uma contribuição bastante original e generosa ao campo educacional. Tal originalidade e generosidade pautam-se em algumas características que considero peculiares: versa acerca de uma temática pouco explorada (ambiente escolar), ainda que seja extremamente importante; os/as autores/as são tanto por pesquisadores/as, em diferentes momentos da carreira acadêmica, quanto docentes e discentes que atuam na Educação Básica, aspecto esse que considero remarcável; percepção essa também expressa por Natália Gil, em seu instigante Posfácio. Essa configuração permitiu uma análise do objeto central da obra – ambiente escolar – por várias perspectivas: Educação (especialmente História da Educação e Psicologia da Educação), Medicina, Geografia, Arquitetura, Psicanálise e dos sujeitos que atuam na Educação Básica.

Published: July 2023

Introducción: es necesario contar con instrumentos válidos y confiables para identificar los factores que influyen en la adherencia al tratamiento en personas con factores de riesgo cardiovascular. En Colombia, Bonilla y Gutiérrez diseñaron un instrumento que cuenta con validez facial y de contenido. Sin embargo, no se ha demostrado la validez de constructo. Objetivo: determinar la validez de constructo y confiabilidad del instrumento, factores que influyen en la adherencia al tratamiento farmacológico y no farmacológico en personas con factores de riesgo cardiovascular. Metodología: investigación metodológica. Participaron 694 personas con factores de riesgo de enfermedad cardiovascular residentes en tres ciudades de Colombia (Neiva, Espinal y Tunja). Se realizó un análisis factorial exploratorio (extracción de componentes principales y rotación Varimax), análisis factorial confirmatorio (estimación de máxima verosimilitud) y una prueba de confiabilidad global y por dimensiones (alfa de Cronbach y Test-retest). Resultados: el análisis factorial exploratorio reportó un instrumento de 30 ítems con estructura de 4 factores (varianza total acumulada de 42,6 %). Los índices de ajuste del modelo propuesto indicaron ajuste absoluto excelente y ajuste incremental aceptable. El alfa de Cronbach global fue 0,86, lo que indica alta confiabilidad. Discusión: el estudio proporciona evidencia de un instrumento más robusto que otras versiones. Los instrumentos estandarizados para medir factores que influyen en la adherencia pueden ser muy útiles para la investigación y la práctica si cumplen con pruebas psicométricas de fiabilidad y validez. Conclusión: se pone a disposición de los investigadores y del personal de salud un instrumento válido y confiable. Se recomienda su uso en poblaciones similares a la de este estudio.

Objective The immune response is a double-edged sword, and
COVID-19 shares similarities with pancreatitis in terms of natural
immune response, immune storm, and multi-organ involvement. However,
whether a causal association between them remained unclear. This study
aimed to investigate the potential causal association between COVID-19
and pancreatitis using a bidirectional Mendelian Randomization (MR)
approach. Methods The study analyzed three variables related to
COVID-19 (severity, hospitalization, and susceptibility) with a sample
size ranging from approximately 1,059,456 to 1,557,411. Additionally,
four types of pancreatitis (acute, chronic, alcohol-induced acute, and
chronic) were examined, with a sample size ranging from 337,126 to
377,277. Causal associations were estimated using inverse-variance
weighted (IVW), median weighted, and MR-Egger methods. Results
The IVW model indicated potential causal associations between genetic
susceptibility to severe and hospitalized COVID-19 and a decreased risk
of acute pancreatitis (OR = 0.914, p = 0.01; OR = 0.884, p = 0.008) and
alcohol-induced chronic pancreatitis (OR = 0.852, p = 0.013; OR = 0.768,
p = 0.002), including chronic pancreatitis. Inconsistent
associations were observed between IVW and sensitivity analyses in acute
and chronic pancreatitis of severe and hospitalized COVID-19.
Conversely, no significant associations were found between pancreatitis
traits and COVID-19-related variables in reverse MR analysis. No
heterogeneity or pleiotropy was found. Conclusions Host genetic
liability to severe and hospitalized COVID-19 was causally associated
with declining risk of alcohol-induced chronic pancreatitis, while no
significant association was observed for pancreatitis on COVID-19
outcomes. This study has significant implications for unraveling their
pathogenesis and guiding clinical management.
Rejection of Wife towards Iwadh Khulu': A Maqasid Sharia Perspective
Authors: Arfiana Arfiana , B M Taufan , Malkan Malkan
Published: July 2023

Women were perceived as having a nasty and disturbing image in pre-Islamic times. They are considered worthless and subordinated beings whose presence causes many problems. They have no personal independence, their rights can be taken away from them, and their bodies can be trafficked or passed down through the family, which puts them in a precarious situation. Women are considered not worthy of being treated humanely in these circumstances. In Buol Regency, problems have been related to this iwadh khulu'. In this case, the wife did not receive the iwadh khulu' payment that was handed down to her because, during the time of marriage, the wife was treated improperly by her husband, such as not given a living to support her and her children, often being left alone without news, and not infrequently the husband commits domestic violence to the wife. Based on that, the researchers are interested in further researching this issue and have written a thesis entitled "Rejection of Wife towards Iwadh Khulu from a Maqashid Sharia Perspective (Case Study at the Buol Religious Court). The approach used in this research is qualitative. Data was gathered through observation, interviews, and documentation. The analysis was done through data reduction, data presentation, and verification. To ensure that the data obtained was valid and credible, analysis and checking of the validity of the data were carried out. The results of this study indicate that the wife's rejection of iwadh khulu' in the Buol district is based on a mental inability to accept all the burdens she has received during the marriage period. In the view of maqasid sharia, this is included in Hifdz Akl and Hifdz Nasl because refusal is made only based on the wife's mental condition in facing Khulu' (Divorce Lawsuit).
Motyw syreny w sztuce sepulkralnej starożytnej Grecji
Authors: Tatara Magda
Published: July 2023

Syreny znane były w starożytnej Grecji jako pół-ludzie, pół-ptaki. Wzmianki o nich odnaleźć można w źródłach pisanych o tematyce dotyczącej bogów i bohaterów. W sztuce syreny pojawiają się w różnorodnych formach. Liczne zabytki pochodzą ze sztuki sepulkralnej starożytnej Grecji, dlatego celem niniejszej pracy jest analiza motywu syreny właśnie w tym kontekście. Korzystając ze źródeł pisanych oraz opracowań w tekście przedstawiono informacje na temat: pochodzenia syren, ich wyglądu i atrybutów, historii w których pojawiają się syreny (przykładowo: w podróży Odyseusza czy wyprawie Argonautów). Następnie krótko zarysowany został rozwój ikonografii syren w sztuce starożytnej Grecji w różnych epokach. Zasadnicza część dotyczyła analizy oraz interpretacji wizerunków syren z konkretnych zabytków, związanych z tematyką śmierci.
Departure from Randomness: Evolution of Self-Replicators that can Self-Sort through Steric Zipper Formation

Darwinian evolution of synthetic self-replicating entities is likely to have an important role in the emergence of life from inanimate chemical matter. Darwinian evolution of self-replicators requires that these (i) have structural space accessible to them; (ii) occupy only part of this space at any one time, and (iii) navigate this space through a process of mutation and selection. We now report a system of self-replicating hexameric macrocycles that emerges upon mixing two building blocks. It occupies a subset of possible building block sequences. Specific interactions between the building blocks, most likely through steric zipper formation involving the interdigitation of a phenylalanine residue of one building block between two leucine residues of the other building block, results in the preferential formation of a hexamer with a sequence in which the two building blocks alternate. When this system was exposed to two different replication-destruction regimes, different replicator mutant distributions were selected for. When the destruction process was non-selective (mediated by outflow in an open system) the fastest replicating sequences dominated, overriding the preference for zipper formation observed in a closed vial. However, when destruction was mediated chemically (and therefore potentially selective) the replicator mutant that combined adequate resistance to reduction with adequate replication speed and was capable of steric zipper formation, became dominant. These results constitute a rudimentary form of Darwinian evolution where replicators adapt to a changing selection pressure through mutation and selection.
