Published: February 2022

[Abstract] Objective To review the imaging characteristics and
evaluate the diagnostic value of echocardiography for fetal congenitally
unguarded tricuspid valve orifice (CUTVO). Methods Doppler
echocardiography was performed and the images were compared with
operative and necropsy findings in ten fetuses with CUTVO. The aim of
the study was to summarize the characteristics of fetal echocardiography
and analyze the causes of missed diagnoses and misdiagnoses. Results
There were six cases with complete absence and four cases with partial
absence of the tricuspid leaflet. In seven of ten cases the pregnancy
was terminated. In six cases CUTVO was confirmed by
autopsy after induced labor, while one case had no autopsy. After birth,
one case died due to severe illness. The two remaining cases survived
with an atrial septal defect and patent ductus arteriosus on postpartum
ultrasonic scans. These cases underwent surgical treatment resulting in
less moderate tricuspid regurgitation. Among all cases, four were
misdiagnosed and diagnosis for CUVTO missed, but CUVTO was demonstrated
after induced labor. CUTVO ultrasonographic characteristics consist of
the atrioventricular connection with normal arteries and the tricuspid
valve device partially or completely absent. The annulus of the
tricuspid valve can be describe as “empty” in the apical 4-chamber
view, Doppler evaluation shows to-and-fro flow across the tricuspid
orifice with low velocity and two-way spectrum. Conclusion diagnosis and
differential diagnosis of CUTVO by fetal echocardiography has important
clinical value.
Strategic Disclosure and Debt Covenant Violation

Published: February 2022

ABSTRACT
This study examines how managers change their forecasting behavior as a debt covenant violation (DCV) approaches. We find that management forecasts are more optimistic in the quarter before a DCV, and this result is stronger when firms face a higher risk of shifting control rights to lenders in the event of a DCV. Furthermore, we find that managers combine their forecast optimism with actions that are favorable to shareholders but would likely be curtailed by lenders after the DCV. Last, we find managers who are more optimistic in their forecasts are less likely to be replaced after a DCV. Overall, our results are consistent with managers changing their disclosure behavior in an attempt to reduce lenders' awareness of an impending DCV, and thus, buy themselves time to take actions favorable to equity investors.
Erosion Analysis in the Mrica Reservoir Catchment Area in Indonesia using the Soil Erosion Status Method
Authors: Harjadi Beny 
Published: February 2022

The reservoir catchment area (RCA) of Mrica in Banjarnegara district is a powerplant in Central Java with a capacity of 184.5 MW. Mrica Dam, also called the dam of Great Commander General Sudirman, has seen its functions gradually decrease due to sedimentation from massive erosion that has occurred in the upland regions. RCA Mrica, with the upland area in Wonosobo district, has an area of 93,546.4 hectares, consisting of six sub-watersheds, Lumajang, Serayu upstream, Begaluh, Serayu, Tulis and Merawu. In 2017, sedimentation in the dam reached 238,236,588.20 m3/year, resulting from an erosion rate of 524,948.33 tons/year. In light of this serious erosion problem in the Mrica RCA, this study aims to estimate the distribution of the erosion level, categorised as slight, moderate and severe, using the SES (soil erosion status) formula. SES was calculated by mapping the level of each influential aspect: aspect, drainage, land cover, slope and soil texture. The calculation used SRTM (Shuttle Radar Topography Mission) satellite imagery and 2017 Landsat TM7 images. The results show slight erosion (50 tons/ha/year) in 1,468.7 ha (1.6%); moderate erosion (50-100 tons/ha/yr) in 56,258.8 ha (60.1%); and severe erosion ( 100 tons/ha/year) in 35,818.9 ha (38.29%). Sampling in the field took into account the slope class of nine classes and was repeated three times, so the number of samples taken in the field was 27. From field visits to the 27 location points, there was conformity in the results of the sensing analysis is much more than 85%”. The results of the erosion calculation using the SES method showed severe erosion of 27.9% (26,137 ha); moderate erosion of 70.2% (65,679 ha); and slight erosion =of 1.8% (1,731 ha). Further erosion calculation using the SES method needs to be compared with calculation using other methods.

Este análisis del documental Mina del Diablo fue realizado en el marco de la cursada virtual en la cátedra de Metodología de la Investigación en Comunicación (Facultad de Periodismo y Comunicación Social, Universidad Nacional de La Plata, 2021).
Tiene por eje principal explicitar la realidad que se vive en Cerro Rico (Potosí, Bolivia, 2005) en torno a la minería infantil y a los roles naturalizados que se adjudican a los niños en relación al trabajo. Así mismo, se vela por mostrar a los lectores de qué manera operan los sistemas culturales y las creencias, y cómo a partir de ellas se consagra una imagen que permite materializar los principios morales que regulan a este lugar; de esta forma, pretendemos vislumbrar el andamiaje de un contexto territorialmente localizado y temporalmente acotado, reflejando una problemática del periodo 2005 sobre la política organizativa interna del país, junto a sus progresos y deficiencias.

Published: February 2022

Os transtornos alimentares são quadros psiquiátricos que cursam com intenso sofrimento psíquico e diversas complicações clínicas. A avaliação de pacientes com transtornos alimentares costuma exigir uma anamnese minuciosa, exame físico e psíquico detalhado e exames complementares. Nessa avaliação, objetiva-se estabelecer um diagnóstico nosológico do transtorno alimentar e das comorbidades, uma estratificação do risco clínico e psiquiátrico, para então estabelecer um planejamento terapêutico. Após essa avaliação inicial, de acordo com a gravidade do caso, o clínico deve decidir o nível de tratamento recomendado, que pode ser desde a hospitalização até o atendimento ambulatorial regular. Outras decisões, como a via de realimentação, o valor calórico planejado para a realimentação e as metas de recuperação, também devem ser pré-definidas. Sumarizamos, neste artigo, alguns aspectos relacionados à avaliação, comorbidades e orientações gerais de tratamento a partir de três diretrizes internacionais de manejo e tratamento de transtornos alimentares, a saber: duas britânicas, a guideline de transtornos alimentares do National Institute for Health and Care Excellence (NICE) e o Management of Really Sick Patients with Anorexia Nervosa (MARSIPAN); e uma australiana, elaborada pelo Royal Australian and New Zealand College of Psychiatrists (RANZ-CP).
Provenance of metasedimentary rocks of the Kheis Terrane and Kakamas Domain: support for accretionary tectonics during the development of the western Namaqua-Natal metamorphic province
Authors: van Niekerk H.S. , Elburg M.A. , Andersen T. , Armstrong R.A. 
Published: February 2022

Abstract
The ~1 200 to 1 000 Ma Namaqua-Natal Metamorphic Province (NNMP) is part of a major orogenic belt in the west-central parts of South Africa and most likely formed during the convergence of the Laurentia and Kalahari cratons during the assembly of Rodinia. Controversy exists regarding the mode of formation of the Namaqua sector of the NNMP, with some supporting the idea of accretion of different crustal fragments while others argue that it formed in a continental back-arc setting. Here we address this controversy and provide information regarding the provenance of two metasedimentary successions that are preserved to the east and west of the Trooilapspan shear zone, which represents the Eastern Namaqua Front. 207Pb/206Pb SHRIMP ages for detrital zircon grains sampled from the Keis supergroup, which is preserved in the Kheis Terrane and situated on the Kalahari Craton, support derivation from Archaean to Paleoproterozoic source areas on the Kaapvaal Craton. In contrast, SHRIMP ages from detrital zircon grains of the Korannaland Group, which forms the metamorphosed supracrustal sequence of the Kakamas Domain, show derivation from late-Paleoproterozoic to Mesoproterozoic source areas like the Bushmanland and Richtersveld domains as well as the gneissic basement of the Kakamas Domain. The zircon age distribution data show that the metasedimentary rocks of the Keis supergroup and Korannaland Group did not obtain detrital material from the same source areas during their deposition, and that the Keis supergroup never served as a source for the detrital material in the Korannaland Group. This indicates that these successions had different geological histories prior to the formation of the NNMP, which supports the accretionary model for the development of the Namaqua Sector of the NNMP.
