Published: November 2021

In this work, we analyzed the current-voltage characteristics in the temperature range of the hybrid organic material C24H24N6O3Zn in order to determine the prospects for using this compound as a semiconductor material. The range of temperature measurements was from 270 to 330 K. An electrochemical analysis of the studied coordination compound was carried out,

the energies of the HOMO and LUMO levels were calculated. The method of obtaining, microscopy, and also the method of measuring the temperature dependences of the electrical

properties of the obtained thin films of these hybrid materials based on zinc complexes are described. A number of fundamental values of the films of this coordination compound have

been calculated: the activation energy is  0.88 eV and the mobility of charge carriers is  1.4710-11 cm V-1 s-1.

Discute a relação da rede social Instagram com a memória, a fim de tornar compreensíveis seus constructos teóricos basilares e suas características com o objetivo de chamar a atenção para a importância para a fotografia como memória visual do mundo físico e natural. Sontag (1981) afirma que com o tempo a fotografia começou um processo de “[...] democratização de todas as experiências através de sua tradução por imagens” e, para tanto, este trabalho, do ponto de vista teórico, busca os estudos e relatos sobre como a plataforma Instagram, contribui para manutenção do memorial dos usuários post-mortem através da função memorial e dos perfis que fazem homenagens póstumas de usuários. Trata-se de uma pesquisa de natureza qualitativa, com levantamento bibliográfico, documental e relatos como procedimento para a construção do referencial teórico. Conclui-se, diante da temática, que a fotografia, mesmo no ambiente das redes sociais, ainda conserva seu caráter simbólico, ocasionalmente criando identificação tanto com o objeto retratado, quanto com a representação de um momento, uma experiência ou um passado.

Abstract. Midlatitude mixed-phase stratocumulus clouds and their interactions with
aerosols remain poorly understood. This study examines the roles of ice
processes in those clouds and their interactions with aerosols using a
large-eddy simulation (LES) framework. Cloud mass becomes much lower in the
presence of ice processes and the Wegener–Bergeron–Findeisen (WBF) mechanism
in the mixed-phase clouds compared to that in warm clouds. This is
because while the WBF mechanism enhances the evaporation of droplets, the
low concentration of aerosols acting as ice-nucleating particles (INPs) and
cloud ice number concentration (CINC) prevent the efficient deposition of
water vapor. Note that the INP concentration in this study is based on the
observed spatiotemporal variability of aerosols. This results in the lower
CINC compared to that with empirical dependence of the INP concentrations
on temperature in a previous study. In the mixed-phase clouds, the
increasing concentration of aerosols that act as cloud condensation nuclei
(CCN) decreases cloud mass by increasing the evaporation of droplets through
the WBF mechanism and decreasing the intensity of updrafts. In contrast to
this, in the warm clouds, the absence of the WBF mechanism makes the
increase in the evaporation of droplets inefficient, eventually enabling
cloud mass to increase with the increasing concentration of aerosols acting
as CCN. Here, the results show that when there is an increasing
concentration of aerosols that act as INPs, the deposition of water vapor is
more efficient than when there is the increasing concentration of aerosols
acting as CCN, which in turn enables cloud mass to increase in the
mixed-phase clouds.

Abstract. A Zeppelin airship was used as a platform for in-situ measurements of greenhouse gases and short-lived air pollutants within the planetary boundary layer in Germany. A novel quantum cascade laser-based multi-compound gas analyzer (MIRO Analytical AG) was deployed to simultaneously measure in-situ concentrations of greenhouse gases (CO2, N2O, H2O, and CH4) and air pollutants (CO, NO, NO2, O3, SO2, and NH3) with high precision at a measurement rate of 1 Hz. These measurements were complemented by electrochemical sensors for NO, NO2, Ox (NO2+O3), and CO, an optical particle counter, temperature, humidity, altitude, and position monitoring. Instruments were operated remotely without the need for on-site interactions. Three two-week campaigns were conducted in 2020 comprising commercial passenger as well as targeted flights over multiple German cities including Cologne, Mönchengladbach, Düsseldorf, Aachen, Frankfurt, but also over industrial areas and highways. Vertical profiles of trace gases were obtained during the airship landing and take-off. Diurnal variability of the Zeppelin vertical profiles was compared to measurements from ground-based monitoring stations with a focus on nitrogen oxides and ozone. We find that their variability can be explained by the increasing nocturnal boundary layer height from early morning towards midday, an increase in emissions during rush hour traffic, and the rapid photochemical activity midday. Higher altitude (250–450 m) NOX to CO ratios are further compared to the 2015 EDGAR emission inventory to find that pollutant concentrations are influenced by transportation and residential emissions as well as manufacturing industries and construction activity. Finally, we report NOx and CO concentrations from one plume transect originating from a coal power plant and compare it to the EURAD-IM model to find agreement within 15 %. However, due to the increased contribution of solar and wind energy and/or the impact of lockdown measures the power plant was operated at max. 50 % capacity; therefore, possible overestimation of emissions by the model cannot be excluded.

Published: November 2021

Abstract. Trees record climatic conditions during their growth, and
tree rings serve as proxy to reveal the features of the historical climate
of a region. In this study, we collected tree-ring cores of hemlock forest
(Tsuga forrestii) from the northwestern Yunnan area of the southeastern Tibetan Plateau
(SETP) and created a residual tree-ring width (TRW) chronology. An analysis
of the relationship between tree growth and climate revealed that
precipitation during the non-growing season (NGS) (from November of the
previous year to February of the current year) was the most important
constraining factor on the radial tree growth of hemlock forests in this
region. In addition, the influence of NGS precipitation on radial tree
growth was relatively uniform over time (1956–2005). Accordingly, we
reconstructed the NGS precipitation over the period spanning from 1600–2005.
The reconstruction accounted for 28.5 % of the actual variance
during the common period of 1956–2005. Based on the reconstruction, NGS was
extremely dry during the years 1656, 1694, 1703, 1736, 1897, 1907,
1943, 1982 and 1999. In contrast, the NGS was extremely wet during the
years 1627, 1638, 1654, 1832, 1834–1835 and 1992. Similar variations
of the NGS precipitation reconstruction series and Palmer Drought Severity
Index (PDSI) reconstructions of early growing season from surrounding
regions indicated the reliability of the present reconstruction. A
comparison of the reconstruction with Climate Research Unit (CRU) gridded
data revealed that our reconstruction was representative of the NGS
precipitation variability of a large region in the SETP. Our study provides
the first historical NGS precipitation reconstruction in the SETP which
enriches the understanding of the long-term climate variability of this
region. The NGS precipitation showed slightly increasing trend during the
last decade which might accelerate regional hemlock forest growth.
Sclerochronological evidence of pronounced seasonality from the late Pliocene of the southern North Sea Basin, and its implications

Published: November 2021

Abstract. Oxygen isotope (δ18O) sclerochronology of benthic marine molluscs provides a means of reconstructing the seasonal range in seafloor temperature, subject to use of an appropriate equation relating shell δ18O to temperature and water δ18O, reasonably accurate estimation of water δ18O, and due consideration of growth-rate effects. Taking these factors into account, δ18O data from late Pliocene bivalves of the southern North Sea Basin (Belgium and the Netherlands) indicate a seasonal seafloor range at times larger than now in the area. Microgrowth-increment data from Aequipecten opercularis, together with the species-composition of the bivalve assemblage and aspects of preservation, suggest a setting below the summer thermocline for all but the latest material investigated. This implies a higher summer temperature at the surface than on the seafloor and consequently a greater seasonal range. A conservative (3 °C) estimate of the difference between maximum seafloor and surface temperature under circumstances of summer stratification points to seasonal surface ranges in excess of the present value (12.4 °C nearby). Using model-constrained estimates of water δ18O, summer surface temperature was initially in the cool temperate range (< 20 °C) and then (during the Mid-Piacenzian Warm Period; MPWP) increased into the warm temperate range (> 20 °C) before reverting to cool temperate values (in conjunction with shallowing and a loss of summer stratification). This pattern is in agreement with biotic-assemblage evidence. Winter temperature was firmly in the cool temperate range (< 10 °C) throughout, contrary to previous interpretations. Averaging of summer and winter surface temperatures for the MPWP provides a figure for mean annual sea-surface temperature that is 2–3 °C higher than the present value (10.9 °C nearby) and in close agreement with a figure obtained by averaging alkenone- and TEX86-temperatures for the MPWP from the Netherlands. These proxies, however, respectively underestimate summer temperature and overestimate winter temperature, giving an incomplete picture of seasonality. A higher mean annual temperature than now is consistent with the notion of global warmth in the MPWP, but a low winter temperature in the southern North Sea Basin suggests regional reduction in oceanic heat supply, contrasting with other interpretations of North Atlantic oceanography during the interval. Carbonate clumped isotope (Δ47) and biomineral unit thermometry offer means of checking the δ18O-based temperatures.
New data on gersdorffite and associated minerals from the Peloritani Mountains (Sicily, Italy)
Authors: Mauro Daniela , Biagioni Cristian , Zaccarini Federica
Published: November 2021

Abstract. Gersdorffite, ideally NiAsS, and associated minerals from
Contrada Zillì (Peloritani Mountains, Sicily, Italy) have been
characterized through electron microprobe analysis and X-ray diffraction.
Primary minerals, hosted in quartz veins, are represented by gersdorffite,
tetrahedrite-(Fe), and chalcopyrite with minor pyrite and galena. Rare
aikinite inclusions were observed in tetrahedrite-(Fe) and chalcopyrite.
Gersdorffite occurs as euhedral to subhedral crystals, up to 1 mm in size,
with (Sb,Bi)-enriched cores and (Fe,As)-enriched rims. Its chemical
composition is
(Ni0.79−0.95Fe0.18−0.04Co0.04−0.01)(As0.90−1.03Sb0.10−0.00Bi0.02−0.00)S0.98−0.92.
It crystallizes in the space group P213, with unit-cell parameters a=5.6968(7) Å, V=184.88(7) Å3, and Z=4, and its crystal
structure was refined down to R1= 0.035. Associated tetrahedrite-(Fe)
has chemical formula (Cu5.79Ag0.07)Σ5.86(Cu3.96Fe1.59Zn0.45)Σ6.00(Sb3.95As0.17Bi0.03)Σ4.15S13.06, with unit-cell parameters a= 10.3815(10) Å, V=1118.9(3) Å3, and space group I-43m. Its crystal structure was
refined to R1=0.027. Textural and crystallographic data suggest a
polyphasic crystallization of gersdorffite under low-temperature conditions.

Published: November 2021

Abstract. In the context of global carbon emission reduction, solar
photovoltaic (PV) technology is experiencing rapid development. Accurate localized PV
information, including location and size, is the basis for PV regulation and
potential assessment of the energy sector. Automatic information extraction
based on deep learning requires high-quality labeled samples that should be
collected at multiple spatial resolutions and under different backgrounds
due to the diversity and variable scale of PVs. We established a PV dataset
using satellite and aerial images with spatial resolutions of 0.8, 0.3, and
0.1 m, which focus on concentrated PVs, distributed ground PVs, and
fine-grained rooftop PVs, respectively. The dataset contains 3716 samples of
PVs installed on shrub land, grassland, cropland, saline–alkali land, and water surfaces, as well as flat concrete, steel tile, and brick roofs. The dataset
is used to examine the model performance of different deep networks on PV
segmentation. On average, an intersection over union (IoU) greater than
85 % is achieved. In addition, our experiments show that direct cross
application between samples with different resolutions is not feasible and
that fine-tuning of the pre-trained deep networks using target samples is
necessary. The dataset can support more work on PV technology for greater value, such
as developing a PV detection algorithm, simulating PV conversion efficiency,
and estimating regional PV potential. The dataset is available from Zenodo
on the following website: https://doi.org/10.5281/zenodo.5171712 (Jiang et al., 2021).
Vibration of natural rock arches and towers excited by helicopter-sourced infrasound
Authors: Finnegan Riley , Moore Jeffrey R. , Geimer Paul R.
Published: November 2021

Abstract. Helicopters emit high-power infrasound in a frequency range that
can coincide with the natural frequencies of rock landforms. While a single
previous study demonstrated that close-proximity helicopter flight was able
to excite potentially damaging vibration of rock pinnacles, the effects on a
broader range of landforms remain unknown. We performed a series of
controlled flights at seven sandstone arches and towers in Utah, USA,
recording their vibration response to helicopter-sourced infrasound. We
found that landform vibration velocities increased by a factor of up to 1000
during close-proximity helicopter flight as compared to ambient conditions
immediately prior and that precise spectral alignment between infrasound
and landform natural frequencies is required to excite resonance. We define
admittance as the ratio of vibration velocity to infrasound pressure and
recorded values of up to 0.11 mm s−1 Pa−1. While our results
demonstrate a strong vibration response, the measured velocities are lower
than likely instantaneously damaging values. Our results serve as a basis
for predicting unfavorable degradation of culturally significant rock
landforms due to regular helicopter overflights.
Ontogenetic development of the European basal aquatic turtle Pleurosternon bullockii (Paracryptodira, Pleurosternidae)
Authors: Guerrero Andrea , Pérez-García Adán
Published: November 2021

Abstract. Several British specimens of relatively complete and partial
shells of small pleurosternid turtles, found in the Purbeck Limestone Group
(Berriasian, Lower Cretaceous), are analysed in detail here. Despite having
been found more than a century ago, most of them remained unpublished until
now. Due to the scarce knowledge available to date about the small
individuals of Pleurosternidae from the British record, their taxonomic
status was doubtful. Thus, some authors proposed their attribution to a new
but not defined taxon of small size, whereas others suggested that they
could represent juvenile individuals of Pleurosternon bullockii, the adults of which were also
found in the Purbeck Limestone Group but at different levels. Knowledge
about the shell of the adult individuals of Pleurosternon bullockii has notably increased recently,
abundant information on its intraspecific variability being currently
available. In this context, a detailed study of the small specimens through
qualitative and quantitative approaches is performed here. The results
are evidence a significant range of shape variability because of ontogenetic
development, as well as other types of intraspecific variation such as
inter-individual variation. As a consequence, their attribution to juvenile
individuals of Pleurosternon bullockii is justified, providing new data on the ontogenetic
development of a basal form.

Published: November 2021

Abstract. With the Philippines ranking as the third largest source of plastics that end up in the oceans, there is a need to further explore methodologies that will become an aid in plastic waste removal from the ocean. Manila Bay is a natural harbor in the Philippines that serves as the center of different economic activities. However, the bay is also threatened with plastic pollution due to increasing population and industrial activities. BASECO is one of the areas in Manila Bay where clean-up activities are focused as this is where trash accumulates. Sentinel-2 images are provided free of charge by the European Commission's Copernicus Programme. Satellite images from June 2019 to May 2020 were inspected, then cloud-free images were downloaded. After downloading and pre-processing, spectral data of different types of plastic such as shipping pouch, bubble wrap, styrofoam, PET bottle, sando bag and snack packaging that were measured by a spectrometer during a fieldwork by the Development of Integrated Mapping, Monitoring, and Analytical Network System for Manila Bay and Linked Environments (project MapABLE) were utilized in the selection of training data. Then, indices such as the Normalized Vegetation Index (NDVI), Floating Debris Index (FDI) and Plastic Index (PI) from previous studies were analyzed for further separation of classes used as training data. These training data served as an input to the two supervised classification methods, Naive Bayes and Mixture Tuned Matched Filtering (MTMF). Both methods were validated by reports and articles from Philippine agencies indicating the spots where trash frequently accumulates.
PRELIMINARY INVESTIGATION ON CHLOROPHYLL-A AND TOTAL SUSPENDED MATTER CONCENTRATION IN MANILA BAY USING HIMAWARI-8 AHI AND SENTINEL-3 OLCI C2RCC
Authors: Torres R. B. , Blanco A. C.
Published: November 2021

Abstract. Water quality monitoring is important in maintaining the cleanliness and health of water bodies. It enables us to identify sources of pollutions and study trends. While modern methods include the use of satellite images to estimate water quality parameters, commonly used satellite systems, such as Landsat and Sentinel, only generate images with temporal resolution of 2 to 16 days on the average. Himawari-8 satellite system, on the other hand, generates full-disk images every 10-minutes, making it possible to generate water quality parameters concentration maps more frequently. This paper presents the preliminary analysis of the generation of yearly and seasonal Chlorophyll-a (Chl-a) and Total Suspended Matter (TSM) estimation models using Himawari-8 satellite images and linear regression. Correlation analysis shows that the single spectral bands and band ratios involving Red band have the strongest relationship with Chl-a and TSM. Generated linear regression yearly and seasonal models resulted to R2 values of 0.4 to 0.5 with RMSE values around 3 micrograms/cm3 for Chl-a and 9.5 grams/m3 for TSM. Results also indicate that the seasonal models are better than the yearly models in terms of fit and error. Results from the preliminary investigation will be used to generate a more robust global model in future studies.
SATELLITE IMAGERY DRIVEN ASSESSMENT OF LAND USE LAND COVER, URBANIZATION AND SURFACE TEMPERATURE PATTERN DYNAMICS OVER TROPICAL MEGACITIES
Authors: Verma S. , Agrawal S. , Dutta K.
Published: November 2021

Abstract. In most of the developing nations, fast paced urbanisation is going on. This has changed the spatial patterns of Land Use Land Cover (LULC) and Land Surface Temperature (LST) over time. Continual studies are required in this context to know these phenomena more clearly. This study is carried out to analyse the spatio-temporal changes in LULC, urbanisation and LST in the metropolitan cities of India namely Delhi and Bengaluru. Landsat images of TM and OLI sensors are taken for the years 2001, 2010 and 2020. The LULC layer is obtained through supervised image classification. Concentric circles at the interval of 2 km are drawn from the centroid of the study areas which are used to compute Shannon's entropy through zonal analysis of the reclassified LULC layer. The thermal band of the Landsat is used for the computation of LST. The results of both the study areas revealed 1) decline in the open land, vegetation and water body; 2) rampant growth of built-up and urban area which become more compact over the years; and 3) spread of the higher LST zones.
High-temperature behavior of housed piezoelectric resonators based on CTGS
Authors: Schulz Michal , Ghanavati Rezvan , Kohler Fabian , Wilde Jürgen , Fritze Holger
Published: November 2021

Abstract. A temperature sensor based on piezoelectric single crystals allowing stable operation in harsh environments such as extreme temperatures and highly reducing or oxidizing atmospheres is presented. The temperature dependence of the mechanical stiffness of thickness shear mode resonators is used to determine temperature changes. The sensor is based on catangasite (Ca3TaGa3Si2O14 – CTGS), a member of a langasite crystal family. CTGS exhibits an ordered crystal structure and low acoustic losses, even at 1000 ∘C. The resonance frequency and quality factor of unhoused and of housed CTGS resonators are measured up to about 1030 ∘C. A temperature coefficient of the resonance frequency of about 200 Hz K−1 for a 5 MHz device is found and enables determination of temperature changes as small as 0.04 K. Housed CTGS resonators do not show any significant change in the resonance behavior during a 30 d, long-term test at 711 ∘C.
Interpreting Patient-Reported Outcome Measures
Authors: Meadows Keith
Published: November 2021

Patient-reported outcome measures (PROMs) are valued in healthcare evaluation for bringing patient perspectives forward, and enabling patient-centered care. The range of evidence permitted by PROMs to measure patients’ quality of life narrowly denies subjective experience. This neglect is rooted in the epistemic assumptions that ground PROMs, and the tension between the standardization (the task of measurement) and the individual and unique circumstances of patients. To counter the resulting methodological shortcomings, this article proposes a hermeutical approach and interpretive phenomenology instead of generic qualitative research methods.

“Ruined Cities in Cyprus”
Authors: Konstantinidou Danai
Published: November 2021

At the eve of the twentieth century, Cyprus's British administration perceived the island's medieval structures from a utilitarian point of view; their premises were put to new uses, their stones were removed and reused in new constructions. A mere six years later, selected medieval structures were declared monuments under the then-enacted 1905 Antiquities Law. This article investigates this radical shift and seeks to establish the seminal role of an anonymous letter sent to the Times in December 1899. It argues that these 300 words against the alleged demolition of Famagusta's medieval walls by the British Colonial Office initiated the first steps toward the preservation of medieval structures not only within the town but across the island. Ultimately it seeks to establish that the actions of this six-year period, a response to the letter's allegations, marked the beginning of a process that shaped Cyprus's medieval monuments as we appreciate them today.
In It Together

This article offers an exploratory exegesis of the Buddhist concept of collective karma. My aim is to provide a thicker philosophical account of what this important but rather tricky concept entails. In Buddhist philosophy, karma is a complex topic that is central to Buddhist moral psychology and soteriology. The most common unit of analysis to which karma applies is the individual, however, and it is not altogether clear in what respect karma can be applied to the scale of a community. As collective karma has been taken up in recent years by theorists of engaged Buddhism, clarifying what exactly collective karma is and entails stands to fortify the theoretical basis that underwrites its application to contemporary social and political problems. The main work of this article is, first, to provide a brief exegesis of karma simplicter, and then to analyze two appearances of collective karma in traditional Buddhist literature. To illustrate the practical ramifications of collective karma, I advance the example of the abolitionist theory of transformative justice as a practice of collective karmic self-fashioning.
Apocalyptic Fears in a Time of Dying (of) Whiteness
Authors: Ioanide Paula
Published: November 2021

This article considers what caused the resurgence of white nationalist rage, resentment, and fears before and after Donald Trump was elected to office. For the white working class, declining economic prospects for mobility were sutured to fears of a dying whiteness. The political right used information tactics that normalized a conspiratorial, “post-truth” worldview. For white middle- and upper-class Americans who have been thriving economically since the 1980s, the fears of a dying whiteness were overwhelmingly projected as future possibilities. Such emotional investments in defending whiteness forged a cross-class identification with Trump's white nationalist agenda. At the same time, racial and environmental justice movements made other white Americans increasingly aware that they might be dying of whiteness—a ontological and materialist system that is leading to a collective process of social degradation and ecological self-destruction. The essay speculates on what might motivate white Americans to join a broader divestment from systemic racism and to create a new ontology based on atonement and reparations.
Desire, Truth, and the Role of Narrative Skepticism in Democratic Experience
Authors: Stroud Scott R.
Published: November 2021

Many see narrative as important for life in terms of its persuasive value, including through the process of identification. This article examines narrative and argument with particular attention to how desire and self-image warp processes of narrative judgment and appropriation. In seeking a way to transcend only accepting narratives or storied accounts of important events that confirm what we want to believe, this article proposes the idea of narrative skepticism as a limiting disposition to our reactions to narratives we are poised to accept and those accepted by our partisan opponents. Narrative skepticism, if employed in a positive and pluralistic fashion, can follow through on the ideals posited by thinkers such as John Dewey that involve deeply democratic and unified communities of diverse but respectful partisans.

Este artigo discute a interveniência da sociedade civil na prevenção de riscos hidro-climáticos na Amazônia sul-ocidental, a partir de uma abordagem neo-sistêmica, no Acre, que tem sido palco de enchentes e de incêndios recorrentes e vem se adaptando a este cenário através de uma estrutura de prevenção. De natureza qualitativa e exploratória, este estudo de caso foi construído a partir de levantamento documental e de campo, sendo mapeados e entrevistados 34 gestores de diferentes organizações públicas relacionadas à questão hídrica e climática. Através de análise do conteúdo, os dados permitiram identificar que o Acre enfrentou três grandes ciclos: o de formação do sentido ambientalista; o de diferenciação e estabilização da estrutura, com a presença de iniciativa civil de natureza técnica; o de possível ruptura, ou de riscos às práticas de mitigação. O trabalho conclui que a comunicação facilitada do risco tem sido um dos principais avanços das políticas de prevenção no Acre e isso guarda expressiva relação com a articulação civil; existe uma mudança em curso na orientação mais ambientalista da sociedade acreana que coloca em risco a própria estrutura de prevenção estabelecida.

Durante a fase de implantação da indústria têxtil brasileira, a produção voltou-se para o mercado de tecidos grosseiros, que não demandavam produtos de qualidade. Quando a concorrência com os tecidos estrangeiros passou a exigir a melhoria dos produtos, sentiu-se a ausência do legado de um passado artesanal e do investimento na formação profissional apta a subsidiar a atividade do projeto. Este artigo discute como essa condição promoveu a instalação de procedimentos imitativos em design têxtil.
Ao sul do Equador

Desde fins do século XVIII, as nações europeias perceberam a utilidade das estações navais. A organização de expedições foi uma forma de desenvolver o comércio e de estreitar as relações políticas com regiões extra-europeias. Em 1819, a França enviou as primeiras embarcações para o Brasil. Essas embarcações fizeram parte da Estação Naval do Brasil e do Prata que tinha a missão de realizar o mapeamento hidrográfico das costas brasileiras. A partir de então, as embarcações da estação naval francesa, equipadas com um serviço médico que tinha como obrigação principal a de zelar pela saúde da tripulação, não pararam de navegar pelas costas brasileiras. O corpo de saúde elaborava também relatórios oficiais sobre os acontecimentos mais interessantes e sobre os tratamentos contra doenças. Interessa-nos falar sobre esses relatos de viagens. Esses documentos manuscritos são uma fonte autêntica indispensável para o conhecimento da patologia exótica e das condições de saúde no Brasil. Os relatórios contêm informações que são muito mais do que simples registro de acontecimentos. Eles expõem as impressões dos médicos franceses sobre a paisagem local, impressões estas marcadas pelo determinismo racial e pelo pessimismo no que tange ao clima.
Medicina em versos no Rio de Janeiro oitocentista
Authors: Almeida Anita Correia Lima de
Published: November 2021

Em 1817, o médico italiano Luís Vicente de Simoni chegou ao Rio de Janeiro, onde viveu por mais de seis décadas, até sua morte, em 1881. Durante o tempo em que trabalhou nas instituições de saúde desta cidade, De Simoni também atuou nos campos da tradução e da produção literária, e alguns de seus escritos foram voltados para temas médicos. O presente artigo examina esses escritos, procurando sondar as diversas articulações entre medicina e literatura presentes na obra do médico oitocentista.

Este artigo trata as ligações dissimuladas de caráter militar das expedições científicas organizadas pelo National Bureau of Standards e pela National Geographic Society para a observação do eclipse total do Sol, de 20 de maio de 1947, em Bocaiuva (MG). Nossa intenção é analisar um conjunto de documentos depositados em arquivos no Brasil e nos EUA à luz dos Science and Technology Studies e legitimar esta abordagem dentro da História das ciências. Enfatizaremos o interesse nos resultados que podiam ser alcançados a partir de observações de eclipses do Sol – para sua aplicação nos sistemas de mira de mísseis intercontinentais – como impulsionadores da prática científica.
O paradigma clínico-epidemiológico ou biomédico

Published: November 2021

Este trabalho utiliza como ponto de partida o conceito de paradigma, definido por Thomas S. Kuhn como um conjunto de exemplos compartilhados que orientam, sem ser questionados, a atividade do cientista em seu trabalho habitual, comparando-a com outras visões epistemológicas, detendo-se em especial nas críticas levantadas contra este modelo de descrição da atividade científica e continuando a discutir a possibilidade de estendê-lo à epistemologia do conhecimento médico, com base num padrão para a categoria “doença”.

K2YF5 and K2GdF5 doped with rare earth can be used as thermoluminescent (TL) dosimeters for gamma, beta radiations. In this study, the K2YF5 and K2GdF5 doped with Tb, Pr, Sm, and Dy with different concentrations were synthesized by solid state reaction method. These double fluoride dosimeters were irradiated with different radiations, namely beta and gamma. The study results showed that in general, the TL intensity of K2GdF5 is higher than that of K2YF5. The K2GdF5 crystals doped with Tb3+, Pr3+ have very high TL sensitivities. But the sensitivities of Sm3+, Dy3+ doped- are very low. The TL glow curve of K2YF5:Tb consists of three peaks at temperatures 132oC, 207oC and 240oC, and its intensities are approximately. The TL glow curve of K2GdF5:Tb has dosimetric peak at the temperature 196oC (heating rate 2oC/s), the temperature of this peak suitable for dosimetry application. The TL sensitivity of K2GdF5:Tb is higher than that of TLD-100 and TLD-900 dosimeters for the gamma and beta radiation. The dosimeters K2GdF5:Tb has high sensitivity and linearity for gamma, beta radiations. In addition, the thermal fading effect of TL intensity was very low. The study results showed that these materials can be used in nuclear radiation dosimeters.

Authors: Daulay Munawwaroh , Amri Amri , Syukriah Syukriah
Published: November 2021

PT Pelindo I Cabang Lhokseumawe merupakan pelabuhan yang menyediakan pelayanan dermaga dan fasilitas lain untuk bertambat, bongkar muat peti kemas, curah cair dan curah kering. Dalam prakteknya, terdapat beberapa jenis pemborosan pada proses pembongkaran peti kemas yang dapat menurunkan produktivitas perusahaan. Permasalahan dalam penelitian ini adalah waktu proses pembongkaran peti kemas tidak sesuai dengan standar yang di tetapkan oleh perusahaan yaitu 20 container/jam sedangkan di lapangan hanya dapat membongkar 9 container/jam. Hal ini disebabkan oleh aktivitas yang tidak memiliki nilai tambah yang berdampak pada waktu transportasi dan waktu menunggu yang lama. Tujuan dari penelitian ini adalah mengidentifikasi waste yang terdapat pada aliran proses pembongkaran peti kemas dan mengusulkan perbaikan guna mengeliminasi waste. Metode yang digunakan adalah lean service dan Value Stream Mapping. Berdasarkan hasil perhitungan data diketahui bahwa jenis pemborosan yang paling berpengaruh adalah transportasi sebesar 45,60% dan waiting sebesar 29,47%. Oleh karena itu, usulan perbaikan adalah perlunya penjadwalan dan pengalokasian waktu bongkar muat, penyediaan crane dengan kondisi yang sesuai, pelatihan bagi operator dan pembuatan SOP slot penyusunan peti kemas. Hasil perhitungan usulan perbaikan setelah penerapan lean service menunjukkan jumlah container mengalami peningkatan dari 9 container/jam menjadi 12 container/jam, penurunan waktu lead time dari 413,03 detik menjadi 300,06 dan peningkatan Process Cycle Efficiency dari 34,04% menjadi 58,75%, hal ini bermakna bahwa adanya peningkatan produktivitas perusahaan setelah penerapan lean service.

Pure anterior bilateral shoulder dislocations are rare clinical features, especially in traumatic forms. They are most often posterior, occurring during an epileptic seizure. Few cases are described in the literature, and the mechanism varies from case to case. We report a specific case of pure bilateral anterior shoulder dislocation in a 29-year-old judo player following an accident during his training and discuss the circumstances, mechanism, treatment, and prognosis.
