Authors: Nugroho Bagus , Dharmawati Nuraeni Dwi , Faizah Kuni
Published: May 2022

Isu kehilangan minyak sawit akibat rangkaian proses pada pabrik kelapa sawit merupakan permasalahan yang perlu diatasi. Sludge centrifuge merupakan unit penyaring pada stasiun klarifikasi yang dapat menurunkan losses minyak. Penelitian ini bertujuan untuk mengetahui efektivitas sludge centrifuge dalam mengutip minyak di PT. Eka Dura Indonesia. Sampel sebanyak 100 ml diambil dari buffer tank sebagai input pada sludge dengan kandungan minyak (14,53%), emulsi (10,93%), air (60,33 %) dan NOS (20,60%). Keluaran dari sludge centrifuge berupa light phase dan heavy phase. Light phase memiliki komposisi (13,47%), emulsi (10,50%), air (59,10%) dan NOS (16,93%). Heavy phase terdiri dari oil wet basis (OWB) dan oil dry basis (ODB). Oil wet basis (OWB) merupakan penanda terjadinya kehilangan minyak. Hasil penelitian menunjukkan bahwa OWB/minyak sebesar 0.82%. Hal tersebut sesuai dengan standar yang ditetapkan oleh pabrik yakni dibawah 1 %. Selanjutnya kandungan minyak total pada sludge umpan memiliki korelasi positif dengan kandungan minyak light phase sludge centrifuge (R = 0,996).
Mamanwa Ritual Dances of Surigao del Sur
Authors: M. Arimang Nancy Marie
Published: May 2022

Mamanwa ritual dances do not only define but also, more importantly, direct the choreographic ideas and history of the Mamanwas. The purpose of this ethnographic study was to ascertain the fundamental characteristics of Mamanwa ritual dances in terms of their nature, clothing, accessories and equipment, dance patterns, musical accompaniment, tempo, and the cultural values expressed in each ritual dance. The ethnographic approach was employed in this study to gain a thorough understanding of the ritual dances. It extensively used observations, analytical description, and qualitative judgment or interpretation in order to provide a comprehensive picture of Mamanwa ritual dances in Lanuza, Cortes, and Buenavista. Mamanwa ritual dances are conducted to express gratitude, thanksgiving and beseech favors from Tahaw, their supreme god. They make extensive use of altars and offerings. As a result of their wandering lifestyle, they were unable to retain or maintain even one of their traditional costumes. Tap, leap, close step, parallel tortilier, hop, stamp, slide, kick, mincing, and shuffling are the dance steps utilized. All their ritual dances are accompanied by the gimbar/gimbe-e and gong's percussive sound. All three ritual dances are characterized by dedication, reverence, and humility, which are expressed through the dance steps and arm and body movements. This choreographic history will instil in the youths an appreciation for our race's history, motivate our artists to be more active and engaged, and enlighten our society's cultural inclinations and beliefs.
,Jede Schicht ein Kunstwerk‘: Postmemoriale Autofiktion und Autorschaft in Herta Müllers Atemschaukel
Authors: Bauer Karin
Published: May 2022

Abstract Die literarische Wertschätzung des ,,Gulag-Romans“ ist meist gebunden an autobiografische und überwiegend männlich kodierte Prosa, die als Ausdruck und Garantie von persönlicher und historischer Authentizität (miss)verstanden wird.
Anhand von Herta Müllers als ,,parfümiert“ kritisierten Roman Atemschaukel argumentiert dieser Beitrag, dass der Wahrheitsgehalt des postmemorialen Lagerromans nicht in der vermeintlichen Authentizität persönlicher Erinnerung liegen kann, sondern dass es in
Atemschaukel vielmehr darum geht, narrative Möglichkeiten auszuloten, durch die das Leiden in einer existentiellen Ausnahmesituation vermittelt werden kann. Müllers Begriffe der Autofiktion und erfundenen Erinnerung sind desweilen im Sinne Ruth Klügers ,,anders geschliffene
Gläser“, die eine ästhetische Wende in der deutschsprachigen Erinnerungsliteratur (Michael Braun) signalisieren. Der Beitrag liest die auf verschiedenen erzählerischen Ebenen veranschaulichte Verknüpfung von Arbeit und Kunst als einen selbstreflexiven, transgenerationalen
und gegen-monumentalen Dialog über Autorschaft.
Becoming Disposable: Bodies In-Sync and Out-Of-Sync with Method Time in Juli Zeh’s Corpus Delicti
Authors: Pfleger Simone
Published: May 2022

Abstract This article analyzes Juli Zeh’s Corpus Delicti: Ein Prozess (2009) to show how the novel explores the ways in which social, cultural, and political structures control, monitor, and regulate the protagonists’ bodies and construction of their subjectivities.
My discussions of Corpus Delicti foregrounds the possibility that performative acts which at times render the protagonist Mia Holl precariously illegible within the dominant socio-cultural system, while at other times she may still reside within the system. By doing and undoing a state
of belonging and disposability, the character cannot be situated completely and permanently “inside” or “outside” the system. In this vein, Mia challenges the prevalent tendency of some readers to valorize resistance by embracing those instances when she registers as
belonging to the dominant system. Moreover, distinct formal aspects of Zeh’s text prompt readers to pause and potentially re-read passages, encouraging them to interrogate critically their own desire for both a linear narrative and an optimistic resolution with a happy ending.
So wie, wie wenn, als ob: Literarische Tiere und Tierliche Tropen in Eva Menasses Tiere für Fortgeschrittene (2017)
Authors: Gruber Julia K.
Published: May 2022

Abstract Angelehnt an Theorieansätze von John Berger und Jacques Derrida sowie unter Berücksichtigung der Literary Animal Studies, untersucht dieser Beitrag Eva Menasses Erzählband Tiere für Fortgeschrittene (2017). Dabei steht Menasses Spiel mit
tierlichen Tropen, d.h. Vergleichen, Metaphern, Allegorien und Ironie und wie sie ,,Fabelhaftes” schreibt, im Zentrum der Analyse. In Tiere für Fortgeschrittene wird das Verhalten, das Leiden und das Geschick von Tieren auf die in den Geschichten beschriebenen Menschen bezogen.
Als Leserin wird man so aufgefordert, das tierliche und das menschliche Verhalten in Beziehung zueinander zu setzen. Der Essay zeigt auf, welche Art Interaktion zwischen Tieren und Menschen bzw. zwischen Autorin und Leserin zustande kommt, wenn Menasse auf diese Weise Tierinformationen mit
Geschichten über Menschen verbindet. Zuletzt wird der Erzählband als Beispiel für interspezielle Kunst diskutiert.
Lesbian Camp and the Queer Archive: Angela Steidele’s Rosenstengel: Ein Manuskript aus dem Umfeld Ludwigs II. (2015)
Authors: Schlipphacke Heidi
Published: May 2022

Abstract Angela Steidele’s 2015 epistolary novel Rosenstengel: Ein Manuskript aus dem Umfeld Ludwigs II presents a queer archive via partially fictional letters from and about Ludwig II and the cross-dressing lesbian Catharina Margaretha Linck, who lived more
than 100 years before the Bavarian king. Steidele’s novel highlights the marriage of materiality and fantasy within the queer archive, engaging a mode of Camp aesthetics that always points to the gap between the material/real and fantasy. What is more, it is lesbian Camp, an undertheorized
concept, that shapes and structures Steidele’s novel, even those portions concerned with the homosexually-inclined King Ludwig. The unrepresentability of lesbian desire surfaces in the novel as textual gaps that connote both a joke and loss, underscoring the affective complexity of the
queer archive.

Published: May 2022

Lindi dari proses kegiatan manusia mengandung unsur nutrient yang dapat digunakan sebagai pengganti pupuk urea. Pupuk urea yang digunakan secara komersi seperti alkali dan sodium lignosulfonate masih berpotensi melepaskan ammonia ke udara dengan cukup tinggi. Pemanfaatan lindi sebagai urea berpotensi menimalisasi dampak pencemaran lebih lambat. Tujuan dari studi ini adalah untuk mengetahui percepatan degradasi amonia dalam pemanfattan lindi dan lignin komersil. Pengukuran amonia dalam penelitian ini menggunakan metode phenat. Untuk perhitungan kinetika reaksi digunakan persamaan reaksi pseudo first order. Dengan waktu detensi 80 menit penyisihan lignin berbasis lindi, alkali dan sodium lignosulfonate sebesar 70.2%; 65.6%; dan 81.5%. Sedangkan kecepatan penyisihan amonia dapat mencapai 0.02875/menit; 0.02898/menit; dan 0.0506/menit. Hal ini memperlihatkan bahwa pelepasan amonia dari lindi lebih lambat dari alkali dan sodium lignosulfonate. Akan tetapi signifikansi untuk lindi dan alkali masih tidak terpaut jauh berbeada, oleh karena itu diperlukan penelitian yang lebih mendalam mengenai optimalisasi pemanfaatan lindi sebagai lignin.

Zinc oxide nanostructures for fluorescence and Raman signal enhancement: a review
Authors: Marica Ioana , Nekvapil Fran , Ștefan Maria , Farcău Cosmin , Falamaș Alexandra
Published: May 2022

Since the initial discovery of surface-enhanced Raman scattering (SERS) and surface-enhanced fluorescence (SEF), these techniques have shown huge potential for applications in biomedicine, biotechnology, and optical sensors. Both methods rely on the high electromagnetic fields created at locations on the surface of plasmonic metal nanoparticles, depending on the geometry of the nanoparticles, their surface features, and the specific location of analyte molecules. Lately, ZnO-based nanostructures have been exploited especially as SERS substrates showing high enhancement factors and increased charge transfer effect. Additionally, applications focused on enhancing the fluorescence of analyte molecules as well as on tuning the photoluminescence properties of ZnO nanostructures through combination with metal nanoparticles. This review covers the major recent results of ZnO-based nanostructures used for fluorescence and Raman signal enhancement. The broad range of ZnO and ZnO–metal nanostructures synthesis methods are discussed, highlighting low-cost methods and the recyclability of ZnO-based nanosubstrates. Also, the SERS signal enhancement by ZnO-based nanostructures and the influences of lattice defects on the SERS signal are described. The photoluminescence enhancement of ZnO in the presence of noble metal nanoparticles and the molecular fluorescence enhancement in the presence of ZnO alone and in combination with metal nanoparticles are also reviewed.
Heteroleptic metallosupramolecular aggregates/complexation for supramolecular catalysis
Authors: Howlader Prodip , Schmittel Michael
Published: May 2022

Supramolecular catalysis is reviewed with an eye on heteroleptic aggregates/complexation. Since most of the current metallosupramolecular catalytic systems are homoleptic in nature, the idea of breaking/reducing symmetry has ignited a vivid search for heteroleptic aggregates that are made up by different components. Their higher degree of functional diversity and structural heterogeneity allows, as demonstrated by Nature by the multicomponent ATP synthase motor, a more detailed and refined configuration of purposeful machinery. Furthermore, (metallo)supramolecular catalysis is shown to extend beyond the single "supramolecular unit" and to reach far into the field and concepts of systems chemistry and information science.

Machine Reading Comprehension Using Multi-Passage BERT with Dice Loss on Thai Corpus
Authors: Lapchaicharoenkit Theerit , Vateekeul Peerapon
Published: May 2022

Nowadays there is an advancement in the field of machine reading comprehension task (MRC) due to the invention of large scale pre-trained language models, such as BERT. However, the performance is still limited when the context is long and contains many passages. BERT can only embed a part of the whole passage equal to the input size; thus, sliding windows must be used which leads to discontinued information when the passage is long. In this paper, we aim to propose a BERT-based MRC framework tailored for a long passage context in the Thai corpus. Our framework employs the multi-passage BERT along with self-adjusting dice loss, which can help the model focuses more on the answer region of the context passage. We also show that there is an improvement in the performance when an auxiliary task is used. The experiment was conducted on the Thai Question Answering (QA) dataset used in Thailand National Software Competition. The results show that our method improves the model’s performance over a traditional BERT framework.
Comparative Analysis of Smartphones and Survey-Grade GNSS Receivers for Parcel Boundary Determination
Authors: Oluwadare Caleb , Salami Mary
Published: May 2022

This paper advances the existing body of knowledge on the suitability of accuracy derivable from the use of smartphones for cadastral mapping. Zenvus App software was installed on two smartphones of a different make. A set of dual-frequency GPS Promark 3 receivers and two different smartphones of different make were used for data acquisition. Observations were carried out at the boundaries of ten parcels of land, comprising 46 boundary points. Coordinates of these points were obtained using Differential Global Positioning System (DGPS) observation in static mode and two android smartphones (Samsung A70 and Tecno Spark 3 Pro).  Mean score, root means square error, and one-way analysis of variance was used to show significant differences in the equipment used.  Overall, both the accuracy (mean) and precision (RMSE) were lower than those obtained by Differential GPS. A one-way analysis of variance (ANOVA) was calculated on the values of both X and Y.  For X, the analysis was not significant, F (1, 45)= 0.88, p= 0.419 and for Y, the analysis was also not significant, F(1,45) =0.97, p=0.383. The total RMSE shows that coordinates of points as obtained by the Samsung smartphone (3.368) was more precise than Tecno (4.041). However, the two smartphones (Tecno and Samsung) were less accurate than differential GPS. This implies that there is a 95% chance that the errors in the estimates are less than 6.993m (for Tecno) and 5.848m (for Samsung) respectively. The variation in the observations obtainable with smartphones affects both linear and polygon estimates. The study concluded that the magnitude of these errors is significant in cadastral survey practices and hence not suitable for use. It is recommended that further studies be carried out on the use of the Zenvus app on centimeter grade smartphones probably this could yield a better result suitable for cadastral mapping.
SCHEDULING REPETITIVE CONSTRUCTION PROJECTS: STRUCTURED LITERATURE REVIEW
Authors: Tomczak Michał , Jaśkowski Piotr
Published: May 2022

Construction projects that involve repetitive operations are often referred to as repetitive construction projects. Scheduling them proves a task more demanding than in the case of projects in other industries. Typical objectives of optimization, a characteristic set of constraints, as well as the schedule’s susceptibility to the propagation of disruptions caused by materializing risks, call for specific scheduling methods. The authors review the literature to summarize the existing repetitive scheduling methods and put forward their classification to identify the method’s aspects needing refinement. This is done to point to directions of further research. The authors hope that this study will contribute to better identification of existing problems in planning repetitive construction projects and faster development of decision support systems, eagerly anticipated by the construction practitioners. Though the focus is on applications to construction projects, the repetitive scheduling methods that account for volatile operating conditions may be of interest to researchers who develop planning techniques for other industries.
Ellipsars: Ring-like Explosions from Flattened Stars
Authors: DuPont Marcus , MacFadyen Andrew , Zrake Jonathan
Published: May 2022

The stellar cataclysms producing astronomical transients have long been modeled as either a point-like explosion or jet-like engine ignited at the center of a spherically symmetric star. However, many stars are observed, or are expected on theoretical grounds, not to be precisely spherically symmetric, but rather to have a slightly flattened geometry similar to that of an oblate spheroid. Here we present axisymmetric two-dimensional hydrodynamical simulations of the dynamics of point-like explosions initiated at the center of an aspherical massive star with a range of oblateness. We refer to these exploding aspherical stars as “ellipsars” in reference to the elliptical shape of the isodensity contours of their progenitors in the two-dimensional axisymmetric case. We find that ellipsars are capable of accelerating expanding rings of relativistic ejecta. which may lead to the production of astronomical transients including low-luminosity gamma-ray bursts, relativistic supernovae, and fast blue optical transients
Enhanced Star Formation Activity of Extreme Jellyfish Galaxies in Massive Clusters and the Role of Ram Pressure Stripping
Authors: Lee Jeong Hwan , Lee Myung Gyoon , Mun Jae Yeon , Cho Brian S. , Kang Jisu
Published: May 2022

Jellyfish galaxies are an excellent tool to investigate the short-term effects of ram pressure stripping (RPS) on star formation in cluster environments. It has been thought that the star formation activity of jellyfish galaxies may depend on the host-cluster properties, but previous studies have not yet found a clear correlation. In this study, we estimate the Hα-based star formation rates (SFRs) of five jellyfish galaxies in massive clusters (σ

v,cl ≳ 1000 km s−1) at z ∼ 0.3−0.4 using Gemini GMOS/IFU observations to explore the relationship. Combining our results with those in the literature, we find that the star formation activity of jellyfish galaxies shows a positive correlation with their host-cluster velocity dispersion as a proxy of cluster mass and dynamical states. We divide the jellyfish galaxy sample into two groups with strong and weak RPS signatures using a morphological class. In the phase-space diagram, the jellyfish galaxies with strong RPS features show a higher SFR and a stronger central concentration than those with weak RPS features. We estimate their SFR excess relative to the star formation main sequence (starburstiness; R
SB = SFR/SFRMS(z)) and the density of the surrounding intracluster medium (ICM) using scaling relations with the cluster velocity dispersion. As a result, the starburstiness of jellyfish galaxies with strong RPS signatures clearly exhibits positive correlations with cluster velocity dispersion, ICM density, and strength of ram pressure. This shows that the relation between RPS and star formation activity of jellyfish galaxies depends on the host-cluster properties and strength of the ram pressure.

If the RV slope is due to acceleration from another companion in the system, we show that such a companion is capable of explaining the polar and mildly eccentric orbit of GJ 3470b using two different secular excitation models. The existence of an outer companion can be further constrained with additional RV observations, Gaia astrometry, and future high-contrast imaging observations. Lastly, we show that tidal heating from GJ 3470b’s mild eccentricity has most likely inflated the radius of GJ 3470b by a factor of ∼1.5–1.7, which could help account for its evaporating atmosphere.
Solar-like Dynamos and Rotational Scaling of Cycles from Star-in-a-box Simulations
Authors: Käpylä Petri J.
Published: May 2022

Magnetohydrodynamic star-in-a-box simulations of convection and dynamos in a solar-like star with different rotation rates are presented. These simulations produce solar-like differential rotation with a fast equator and slow poles and magnetic activity that resembles that of the Sun with equatorward migrating activity at the surface. Furthermore, the ratio of rotation to cycle period is almost constant, as the rotation period decreases in the limited sample considered here. This is reminiscent of the suggested inactive branch of stars from observations and differs from most earlier simulation results from spherical shell models. While the exact excitation mechanism of the dynamos in the current simulations is not yet clear, it is shown that it is plausible that the greater freedom that the magnetic field has due to the inclusion of the radiative core and regions exterior to the star are important in shaping the dynamo.
Neutrino Mass Bounds in the Era of Tension Cosmology
Authors: Di Valentino Eleonora , Melchiorri Alessandro
Published: May 2022

The measurements of cosmic microwave background (CMB) anisotropies made by the Planck satellite provide extremely tight upper bounds on the total neutrino mass scale (Σm

ν
< 0.26 eV at 95% C.L.). However, as recently discussed in the literature, the Planck data show anomalies that could affect this result. Here we provide new constraints on neutrino masses using the recent and complementary CMB measurements from the Atacama Cosmology Telescope DR4 and the South Pole Telescope SPT-3G experiments. We found that both the ACT-DR4 and SPT-3G data, when combined with WMAP, mildly suggest a neutrino mass with Σm

In this respect, we note that in these models, CMB+BAO constraints prefer a higher neutrino mass for higher values of the Hubble constant. A combination of ACT-DR4, WMAP, BAO, and constraints on the Hubble constant from the SH0ES collaboration gives

The Universe is Brighter in the Direction of Our Motion: Galaxy Counts and Fluxes are Consistent with the CMB Dipole
Authors: Darling Jeremy
Published: May 2022

An observer moving with respect to the cosmic rest frame should observe a concentration and brightening of galaxies in the direction of motion and a spreading and dimming in the opposite direction. The velocity inferred from this dipole should match that of the cosmic microwave background (CMB) temperature dipole if galaxies are on average at rest with respect to the CMB rest frame. However, recent studies have claimed a many-fold enhancement of galaxy counts and flux in the direction of the solar motion compared to the CMB expectation, calling into question the standard cosmology. Here we show that the sky distribution and brightness of extragalactic radio sources are consistent with the CMB dipole in direction and velocity. We use the first epoch of the Very Large Array Sky Survey combined with the Rapid Australian Square Kilometer Array Pathfinder Continuum Survey to estimate the dipole via several different methods, and all show similar results. Typical fits find a

Formerly considered rare, the ant species Cryptopone ochracea (Mayr, 1855) can be commonly detected using citizen-science tools
Authors: Báthori Ferenc , Jégh Tamás , Csősz Sándor
Published: May 2022

Citizen science is a valuable tool for monitoring different species, especially in cases concerning truly rare and difficult-to-detect species where time-consuming field studies are limited and long-term research projects are uncertain. To better understand the distribution of the rarely collectedCryptopone ochracea(Mayr, 1855) (Hymenoptera, Formicidae) in Hungary, we obtained the occurrence data with photos uploaded by non-professionals to the page of the largest Hungarian Facebook group dealing with ants and a citizen-science website dealing with biological data collection. In this article, we expand the known distribution ofC. ochraceato include 46 new records from Hungary and one from Serbia. With two historical records, this previously undersampled species has now been found 48 times in Hungary. Our results prove that social media platforms and other websites for citizen science projects offer new and useful opportunities for researchers to involve non-professionals in scientific work and, thus, obtain large amounts of valuable data, even for understudied arthropod species.
Spring composition of the macroalgal vegetation of a small offshore island in the north-western Mediterranean (Gallinara Island, Ligurian Sea)

Published: May 2022

Gallinara Island, a small island located 1.5 km off the shore of Liguria (Italy, north-western Mediterranean Sea) was included in a list of proposed Marine Protected Areas (MPA) in the early 90s. Since then, its benthic assemblages have been studied in detail and the main macrophytic communities have been mapped. A detailed assessment of its benthic macroalgal flora, however, has never been made. Gallinara was visited in the course of 5 consecutive years and its macroalgal flora was studied based on collections made by snorkelling and SCUBA diving. Overall, 141 macroalgal taxa were collected and identified (23 Chlorophyta, 94 Rhodophyta, 24 Ochrophyta); 91 of them represent new records for the island. One of the most notable new records is the non-indigenous red alga Womersleyella setacea, previously unreported from the island and widely distributed, particularly on the south-eastern shore. Observations made in the course of the surveys confirm the rarefaction of some large-sized brown algae (particularly Sargassum vulgare) but indicate also that others previously reported as rare (Cystoseira compressa, Dictyopteris polypodioides) are still common on the island.
Non-small cell lung cancer: epidemiology, screening, diagnosis, and treatment

Published: May 2022

Lung cancer is the most common cancer worldwide and is also one of the leading causes of cancer related deaths. The 5-year survival rate depends largely on stage at diagnosis. Multiple large randomized controlled trials have demonstrated the clinical utility of lung cancer screening. Low dose computed tomography is recommended for lung cancer screening in several guidelines. Lung cancer is often diagnosed at more advanced stages owing to the nonspecific symptoms with which it presents. Diagnosis relies primarily upon imaging and biopsy. Diagnosis and staging should be performed simultaneously, if possible, by performing a biopsy at the site that will confer the highest stage. Sufficient material should be obtained to allow for molecular testing. Liquid biopsy may have a complementary role in detecting actionable mutations in non-small cell lung cancer. Treatment is predicated upon stage and may involve surgery, targeted chemotherapy, radiation therapy, immunotherapy, or some combination thereof.
El servicio de transfusión del ejército republicano durante la Guerra Civil Española y su influencia en Gran Bretaña en la Segunda Guerra Mundial
Authors: Palfreeman Linda , Pinkerton Peter H.
Published: May 2022

Al final de la Primera Guerra Mundial, el valor de la transfusión sanguínea era ampliamente reconocido, pero no fue hasta la Guerra Civil Española (1936-1939) cuando se crearon grandes organizaciones civiles de donantes de sangre para proporcionar sangre conservada (citratada) para la transfusión en pacientes civiles y militares en ambos bandos.
Se desarrollaron técnicas de transfusión indirecta para administrar esta sangre, con instrumental de fácil manejo, capaz de ser llevado a cabo en cualquier lugar y por cualquiera con experiencia en la administración de inyecciones endovenosas. También se establecieron sistemas eficaces de transporte y distribución, a fin de abastecer adecuadamente las instalaciones sanitarias que prestaban servicio en los frentes de batalla en movimiento. Este trabajo pionero permitió la creación, por primera vez en la historia, de servicios militares de transfusión de sangre.
Si bien este fue el caso tanto de las fuerzas insurgentes (nacionalistas) como del Gobierno republicano español, es este último el que constituye el foco de estudio aquí. Esto es posible gracias a las publicaciones del hematólogo catalán Frederic Duran Jordà, creador y director del Servicio Republicano de Transfusión de Sangre, que detallan las técnicas y procedimientos desarrollados durante la guerra para la recogida, análisis, distribución y transfusión de sangre. Esta información se amplía, especialmente con respecto a la aplicación práctica de la transfusión en primera línea, gracias a diferentes publicaciones del Dr. Reginald Saxton, voluntario británico integrado en la Sanidad Militar de la Republica.
Es nuestra intención demostrar que las autoridades británicas se beneficiaron de la experiencia española en vísperas del estallido de la Segunda Guerra Mundial en 1939. Les ayudó a desarrollar planes para los servicios de transfusión que resultarían cruciales en el tratamiento de bajas civiles y militares durante la contienda. Frederic Duran Jordà y Reginald Saxton fueron asesores clave, junto con otros que regresaban de España, incluyendo a la reconocida hematóloga británica, Janet Vaughan. Además, los principios desarrollados en España (1936-39) para la práctica militar de transfusiones de sangre siguen respaldando las medidas actuales de reanimación de heridos en el campo de batalla.

Authors: Moraes Jaqueline , Féres-Carneiro Terezinha
Published: May 2022

O presente trabalho, parte de um estudo mais amplo sobre o desejo de filhos da mulher contemporânea, tem como objetivo investigar as motivações de mulheres sem filhos referentes à não maternidade. Para tanto, realizou-se uma pesquisa qualitativa, na qual foram entrevistadas dez mulheres com idades entre 33 e 40 anos, sem filhos, casadas ou em união estável há no mínimo dois anos, atuantes no mercado de trabalho. Os resultados foram analisados de acordo com o método de análise de conteúdo na sua vertente categorial. Para atingir os objetivos formulados neste trabalho, serão discutidas quatro categorias de análise: renuncias e sacrifícios, infância parentalizada, carreira, e legado materno. Os resultados apresentam um maior número de mulheres que rejeitam ou adiam o projeto materno, pela escolha de viver uma vida livre, sem as abdicações que a maternidade demanda. Concluímos que a motivação para a maternidade e para a não maternidade apresenta aspectos conscientes e inconscientes e perpassa a história familiar de cada mulher.
Interação Mãe-Bebê: comparações relacionadas à prematuridade aos três meses de vida do bebê

Published: May 2022

O nascimento pré-termo pode constituir-se como um fator de risco para a interação mãe-bebê, sugerindo estudos com essa população. Este estudo teve como objetivo descrever e comparar comportamentos interativos de díades mães-bebê de dois grupos, um de bebês nascidos pré-termo e outro de bebês nascidos à termo. Participaram 30 mães e seus bebês pré-termo (Grupo PT) e 30 mães e seus bebês a termo (Grupo AT). A interação de cada díade foi filmada durante cinco minutos. O teste t de amostras independentes foi utilizado para comparar os grupos. Os bebês do Grupo PT emitiram significativamente mais os comportamentos de manter contato visual com suas mães e explorar visualmente o ambiente. Também foram maiores os seus totais de comportamentos interativos negativos e não interativos. Os bebês do Grupo AT interagiram e exploraram mais os brinquedos oferecidos pelas mães e emitiram mais comportamentos interativos positivos. As mães do Grupo PT acariciaram e brincaram significativamente mais com seus bebês do que as mães do Grupo AT, que disponibilizaram mais brinquedos para seus bebês. Ressalta-se a importância de investigar padrões de interação mãe-bebê nascidos pré-termo para delinear estratégias que promovam interações positivas entre as díades.
