Analytical Study of Overlooked Bronze Age and Iron Age Goldwork from Northwest Portugal
Authors: Guerra Maria Filomena , Tissot Isabel 
Published: May 2022

To gain further insight into the use of native gold and intentional gold alloys during the Bronze Age in Northwest Portugal, jewellery in the collections of three Portuguese museums was studied using an in-house built portable X-ray fluorescence spectrometer. Among the analysed objects are the Late Bronze Age bracelet from Monte Airoso (Viseu) and the Iron Age tubular bracelet from Regoufe (Aveiro). To shed more light on the manufacture of gold bracelets, have also been analysed all the components (bracelets, wires and bands) of the hoard of Arnozela (Braga), so far incompletely studied. The results obtained show that from the Middle Bronze Age onwards gold containing 8-11 wt.% silver is used, to which gradually increasing amounts of copper seem to have been added over time. These results support a heterogeneous chronology for the components of the hoard of Arnozela and show that the bracelet from Monte Airoso is made from an intentional gold alloy used in the Portuguese area during the Late Bronze Age. On the contrary, the bracelet from Regoufe is made from native gold without addition of copper. This could indicate that at least during a certain period the goldsmiths used both native gold as found and intentional alloys.Two other objects, discussed on the light of the data obtained for the bracelets, complete the study. One of them is one of the two Portuguese Early Bronze Age gold sheet ornaments with cut parallel bands (so-called gargantilha de tiras), found in Braga. Without obvious signs of use-wear like other ornaments of the same type, and made, as expected, with gold hammered into sheet, this ornament is made from an alloy that seems to correspond to a later period using gold from another origin. Finally, the composition of some of the components of the Late Bronze Age-Iron Age string from Malhada (Vila Real), a set of gold decorated plaques made from punched gold sheet by using different and asymmetrical punches, supports the addition of small amounts of copper to gold to produce intentional alloys.
The Lombard Iron Masters Migrations and the Spread of the Blast Furnace in Europe, with a Focus on the 16th-17th Centuries
Authors: Cucini Costanza , Tizzoni Marco 
Published: May 2022

The spread of the blast furnace in some parts of Europe was connected to the migration of miners, iron masters, charcoal burners and entrepreneurs from the Alpine valleys of the Lombard Iron Basin, from what are now the provinces of Bergamo and Brescia (Italy). The authors have gathered all the published evidence from many different sources and arranged it in geographical and chronological order. The preliminary results of the study show that masters provided what we may call an integrated approach to iron production: from the mine to the forge with the optional support of charcoal burners. It seems that they tried to keep their technological knowledge as a trade secret. They were hired trough middlemen, of whom we only know that they acted as intermediaries between the masters and the private entrepreneurs or the rulers. One important reason for the spread of blast furnaces can be seen in the increase in conflicts at the end of the 15th century. These led to a need for blast furnaces in areas of Europe where they had not previously existed.
Development, characterization, and application of an improved online reactive oxygen species analyzer based on the Monitor for AeRosols and Gases in ambient Air (MARGA)

Published: May 2022

Abstract. Excessive reactive oxygen species (ROS) in the human body is an important
factor leading to diseases. Therefore, research on the content of reactive
oxygen species in atmospheric particles is necessary. In recent years, the
online detection technology of ROS has been developed. However, there are
few technical studies on online detection of ROS based on the dithiothreitol (DTT) method.
Here, to modify the instrument, a DTT experimental module is added that
is protected from light and filled with nitrogen at the end based on the
Monitor for AeRosols and Gases in ambient Air (MARGA). The experimental
study found that the detection limit of the modified instrument is 0.024 nmol min−1. The DTT consumption rate of blank sample (ultrapure water)
is reduced by 44 %, which eliminates the influence of outside air and
light in the experiment. And the accuracy of the online instrument is
determined by comparing the online and offline levels of the samples, which
yielded good consistency (slope 0.97, R2=0.95). It shows that the
performance of the instrument is indeed optimized, the instrument is stable,
and the characterization of ROS is accurate. The instrument not only
realizes online detection conveniently and quickly, but also achieves
the hour-by-hour detection of ROS based on the DTT method. Meanwhile,
reactive oxygen and inorganic ions in atmospheric particles are quantified
using the online technique in the northern suburbs of Nanjing. It is found
that the content of ROS during the day is higher than that at night,
especially after it rains; ROS peaks appear in the two time periods of
08:00–10:00 and 16:00–18:00 (China Standard Time, UTC+8:00; expressed here in local time – LT). In addition, examination of the online ROS,
water-soluble ion (SO42-, NO3-, NH4+,
Na+, Ca2+, K+), BC, and polluting gas (SO2, CO,
O3, NO, NOx) measurements revealed that photo-oxidation and
secondary formation processes could be important sources of aerosol ROS.
This breakthrough enables the quantitative assessment of atmospheric
particulate matter ROS at the diurnal scale, providing an effective tool to
study sources and environmental impacts of ROS.
Long-term incubations provide insight into the mechanisms of anaerobic oxidation of methane in methanogenic lake sediments
Authors: Vigderovich Hanni , Eckert Werner , Elul Michal , Rubin-Blum Maxim , Elvert Marcus , Sivan Orit 
Published: May 2022

Abstract. Anaerobic oxidation of methane (AOM) is among the main processes limiting
the release of the greenhouse gas methane from natural environments.
Geochemical profiles and experiments with fresh sediments from Lake Kinneret
(Israel) indicate that iron-coupled AOM (Fe-AOM) sequesters 10 %–15 % of
the methane produced in the methanogenic zone (>20 cm sediment
depth). The oxidation of methane in this environment was shown to be
mediated by a combination of mcr-gene-bearing archaea and pmoA-gene-bearing aerobic
bacterial methanotrophs. Here, we used sediment slurry incubations under
controlled conditions to elucidate the electron acceptors and microorganisms
that are involved in the AOM process over the long term (∼ 18 months). We monitored the process with the addition of 13C-labeled
methane and two stages of incubations: (i) enrichment of the microbial
population involved in AOM and (ii) slurry dilution and manipulations,
including the addition of several electron acceptors (metal oxides, nitrate,
nitrite and humic substances) and inhibitors (2-bromoethanesulfonate,
acetylene and sodium molybdate) of methanogenesis, methanotrophy and sulfate
reduction and sulfur disproportionation. Carbon isotope measurements in the
dissolved inorganic carbon pool suggest the persistence of AOM, consuming
3 %–8 % of the methane produced at a rate of 2.0 ± 0.4 nmol per gram of dry sediment per day. Lipid carbon isotopes and metagenomic analyses
point towards methanogens as the sole microbes performing the AOM process by
reverse methanogenesis. Humic substances and iron oxides, although not sulfate,
manganese, nitrate or nitrite, are the likely electron acceptors used for
this AOM. Our observations support the contrast between methane oxidation
mechanisms in naturally anoxic lake sediments, with potentially co-existing
aerobes and anaerobes, and long-term incubations, wherein anaerobes prevail.
Pliocene evolution of the tropical Atlantic thermocline depth

Published: May 2022

Abstract. It has been hypothesized that global temperature trends are tightly linked
to tropical thermocline depth, and that thermocline shoaling played a
crucial role in the intensification of late Pliocene Northern Hemisphere
glaciation. The Pliocene thermocline evolution in the Pacific Ocean is well
documented and supports this hypothesis, but thermocline records from the
tropical Atlantic Ocean are limited. We present new planktonic foraminiferal
Mg/Ca, δ18O, and δ13C records from the late Pliocene interval at Ocean Drilling Program Site 959 in the Eastern
Equatorial Atlantic (EEA), which we use to reconstruct ocean temperatures
and relative changes in salinity and thermocline depth. Data were generated
using surface-dwelling Globigerinoides ruber and subsurface-dwelling Neogloboquadrina dutertrei. Reduced gradients between
the surface and subsurface records indicate deepening of the EEA thermocline
at the end of the mid-Piacenzian Warm Period (mPWP; ∼ 3.3–3.0 Ma). We connect our late Pliocene records to previously published early
Pliocene δ18O data from Site 959 and compare these to the Site 1000 in the Caribbean Sea. Over the course of the Pliocene, thermocline changes in the EEA and Caribbean Sea follow similar patterns, with prominent
step-wise thermocline deepening between ∼ 5.5 and 4.0 Ma and
gradual shoaling up to the mPWP, followed by minor deepening at the end of
the mPWP. The tropical thermocline depth evolution of the tropical Atlantic
differs from the Pacific, which is characterized by gradual basin-wide
shoaling across the Pliocene. These results potentially challenge the
hypothesized link between tropical thermocline depth and global climate. The
mechanisms behind the periodically divergent Pacific and Atlantic
thermocline movements remain speculative. We suggest that they are related
to basin geometry and heterogenous temperature evolutions in regions from
where thermocline waters are sourced. A positive feedback loop between
source region temperature and tropical cyclone activity may have amplified
tropical thermocline adjustments.
Development of East Asia Regional Reanalysis based on advanced hybrid gain data assimilation method and evaluation with E3DVAR, ERA-5, and ERA-Interim reanalysis
Authors: Yang Eun-Gyeong , Kim Hyun Mee , Kim Dae-Hui 
Published: May 2022

Abstract. The East Asia Regional Reanalysis (EARR) system is developed based on the
advanced hybrid gain data assimilation method (AdvHG) using the Weather Research
and Forecasting (WRF) model and conventional observations. Based on EARR,
the high-resolution regional reanalysis and reforecast fields are produced
with 12 km horizontal resolution over East Asia for 2010–2019. The newly
proposed AdvHG is based on the hybrid gain approach, weighting two different
analyses for an optimal analysis. The AdvHG differs from the hybrid
gain in that (1) E3DVAR is used instead of EnKF, (2) 6 h forecast of ERA5 is
used to be more consistent with WRF, and (3) the preexisting,
state-of-the-art reanalysis is used. Thus, the AdvHG can be regarded as an
efficient approach for generating regional reanalysis datasets thanks to cost
savings as well as the use of the state-of-the-art reanalysis. The upper-air
variables of EARR are verified with those of ERA5 for January and July 2017
and the 10-year period 2010–2019. For upper-air variables, ERA5
outperforms EARR over 2 years, whereas EARR outperforms (shows comparable
performance to) ERA-I and E3DVAR for January 2017 (July 2017). EARR represents precipitation better than ERA5 for January and July 2017.
Therefore, although the uncertainties of upper-air variables of EARR need to
be considered when analyzing them, the precipitation of EARR is more
accurate than that of ERA5 for both seasons. The EARR data presented
here can be downloaded from https://doi.org/10.7910/DVN/7P8MZT
(Yang and Kim, 2021b) for data on pressure levels and https://doi.org/10.7910/DVN/Q07VRC (Yang and Kim, 2021c) for precipitation.
Weakening and warming of the European Slope Current since the late 1990s attributed to basin-scale density changes
Authors: Clark Matthew , Marsh Robert , Harle James 
Published: May 2022

Abstract. Oceanic influences on shelf seas are mediated by flow along and across continental slopes, with consequences for regional hydrography and
ecosystems. Here we present evidence for the variable North Atlantic influence on European shelf seas over the last 4 decades using ocean
analysis and reanalysis products, as well as an eddy-resolving ocean model hindcast. To first order, flows oriented along isobaths at the continental slope
are related to the poleward increase in density in the adjacent deep ocean that supports a geostrophic inflow towards the slope. In the North
Atlantic, this density gradient and associated inflow have undergone substantial, sometimes abrupt, changes in recent decades. Inflow in the range
10–15 Sv is identified with eastward transport in temperature classes at 30∘ W in the latitude range
45–60∘ N. Associated with major subpolar warming around 1997, a cool and fresh branch of the Atlantic inflow was substantially reduced,
while a warm and more saline inflow branch strengthened, with respective changes of the order of 5 Sv. Total inflow fell from
∼ 15 Sv pre-1997 to ∼ 10 Sv post-1997. In the model hindcast, particle tracking is used to trace the origins of poleward
flows along the continental slope to the west of Ireland and Scotland before and after 1997. Backtracking particles up to 4 years, a range of
subtropical and subpolar pathways is identified from a statistical perspective. In broad terms, cold, fresh waters of subpolar provenance were
replaced by warm, saline waters of subtropical provenance. These changes have major implications for the downstream shelf regions that are strongly
influenced by Atlantic inflow, in particular the northern North Sea, where “subtropicalization” of ecosystems has already been observed since the
late 1990s.

Published: May 2022

Este estudo tem como objetivo analisar como o Movimento Negro (MN) brasileiro, pós década de 1970, contribuiu na luta pela garantia do direito à educação da população negra brasileira. Para isso, realizamos uma pesquisa bibliográfica, com o emprego de revisão de literatura com base nos autores: Domingues (2007; 2008), Gomes (2012), Gonçalves e Silva (2000), Passos e Nogueira (2014), Pereira (2010), Alberto (2017), entre outros. Os resultados apontam que, desde sua reorganização em 1978, o MN atuou incisivamente para que o direito à educação da população negra fosse garantido, resultando em importantes conquistas, tanto no acesso como na permanência em instituições de ensino, em particular, naquelas de nível superior. Na atualidade, o refluxo das políticas de reparação e promoção da igualdade racial tem sido um grande desafio a ser superado pelo MN, requerendo sólidas estratégias de resistência.

Published: May 2022

Este artigo enfoca, no campo científico, uma reflexão sobre a práxis educativa centenária do educador Paulo Freire. Para tanto, como abordagem metodológica, emprega-se uma análise bibliográfica, de cunho qualitativo, ao revisar os aspectos marcantes do trabalho, a fim de evidenciar a literatura de clássicos de Paulo Freire e de outros autores que pesquisaram a sua vasta obra. Conforme contexto histórico da educação, destaca-se a Pedagogia Freiriana, até então repugnada pela classe conservadora, por não corresponder aos interesses dominantes, mas de suma importância enquanto prática alinhada à autonomia, ao diálogo, e ao relacionamento humanitário. Ademais, comemorar o centenário desse grande educador em meio a uma pandemia instaurada é tentar acreditar mais no ser humano, na amorosidade e numa sociedade mais dialógica para todos e todas, apesar das retas e curvas interpostas, sobretudo no caminho educacional brasileiro.

Autoimmune Dermatitis associated with Endogenous Progesterone Hypersensitivity: a case report
Authors: Nogueira Rodrigues Andrea Railla , Matos Oliveira Paula 
Published: May 2022

Progesterone hypersensitivity (HP), also known as autoimmune progesterone dermatitis, is a rare condition with dermatological or systemic manifestations associated with progestogen, whether endogenous or synthetic. Its symptoms appear in the luteal phase and precede the menstrual flow a few days and may extend after the end of menstruation. The pathophysiology is still uncertain, and some hypotheses have been published in an attempt to explain the cases associated with both endogenous and synthetic progesterone. The diagnosis is clinical, but some tests are described in an attempt to help confirm the diagnosis. Hormonal contraceptives, antihistamines, corticosteroids and even bilateral oophorectomy are therapeutic options described. This paper describes the case report of a 28-year-old woman, nulliparous, with symptoms of macules and papules that started three days before the menstrual flow, without external triggering factor. After using a combined oral contraceptive and antihistamine, she progressed with significant clinical improvement. In view of these points and due to the scarcity of evidence on hypersensitivity to progesterone, it is essential to produce more studies on the clinical presentation, triggering factors and therapeutic possibilities for a better diagnostic elucidation and treatments of these patients.
