A switch from horizontal compression to vertical extension in the Vrancea slab explained by the volume reduction of serpentine dehydration

The Vrancea slab, Romania, is a subducted remnant of the Tethyan lithosphere characterized by a significant intermediate-depth seismicity (60–170 km). A recent study showed a correlation between this seismicity and major dehydration reactions, involving serpentine minerals up to 130 km depth, and high-pressure hydrated talc deeper. Here we investigate the potential link between the triggering mechanisms and the retrieved focal mechanisms of 940 earthquakes, which allows interpreting the depth distribution of the stress field. We observe a switch from horizontal compression to vertical extension between 100 and 130 km depth, where the Clapeyron slope of serpentine dehydration is negative. The negative volume change within dehydrating serpentinized faults, expected mostly sub-horizontal in the verticalized slab, could well explain the vertical extension recorded by the intermediate-depth seismicity. This apparent slab pull is accompanied with a rotation of the main compressive stress, which could favour slab detachments in active subduction zones

Overlap mechanisms of transient global amnesia and COVID-19 infection: review

Background: An increasing number of patients with Transient Global Amnesia (TGA) was reported during the COVID-19 pandemics. However, there are limited data on the mechanisms of TGA linked with this infection. The aim of the study was to analyze the effect of COVID-19 infection on the hippocampal function and its potential mechanisms for TGA. A narrative literature review was performed, while searching on PubMed the following keywords: “transient global amnesia”, “COVID-19”, “hippocampus”. Ten English-written publications (clinical cases, cross-sectional studies, prospective studies) were selected. The time period covered was 2019 – 2021. During recovery from COVID-19, frequent cases of neurocognitive deficits (78%) were reported. It’s also known that TGA can be triggered by physical and emotional stress. It is possible that TGA’s pathogenesis (arterial ischemia, venous congestion, metabolic stress) could involve the CA1 hippocampal region – the most sensitive area to hypoxia, linked to afferent inputs from the medial and lateral entorhinal cortexes. These regions include high concentrations of Zinc ions and play a key role in modulating memory and spatial learning. Meantime, SARS-CoV-2 was previously detected in the olfactory bulb, amygdala, entorhinal, temporal and frontal cortex (20%); and most severe cases COVID-19 were associated with Zinc deficiency (57.4%). Conclusions: The review highlights the precipitating events for TGA and their implications at the hippocampal level, jointly with similar pathophysiological changes reported in the novel coronavirus infection. This could explain the effect of COVID-19 infection on the hippocampus function and the potential mechanisms for TGA

Tachyarrhythmias in pregnancy, case report

Disciplina Cardiologie, Clinica Medicală nr.3, Departamentul Medicină Internă, Catedra Obstetrică şi Ginecologie FCMF USMF „Nicolae Testemiţanu”,IMSP Institutul Mamei şi CopiluluiSinus tachycardia (TS) is a heart rhythm disorder characterized by the acceleration of sinusal rhythm, 100 beats / minute. TS is a physiological response to effort, stress, pregnancy, and in diseases: hyperthyroidism, myocardial infarction, pulmonary artery thromboembolism, infections, anemia, bleeding, neuroses, etc.. During pregnancy the heart rate increases by 25%, thus TS, especially in the third trimester, reaches an incidence of 50% (non-sustained arrhythmia) and sustained tachycardias have a lower frequency – 2 - 3 to 1000 pregnant. We present the clinical case of a pregnant of 28 years with sinus tachycardia clinically and electrocardiographicaly manifested, with adequate response to treatment. Tahicardia sinusală (TS) este o tulburare de ritm cardiac caracterizată prin accelerarea ritmului sinusal, peste 100 bătăi/minut. TS se declanşează ca răspuns fiziologic la efort, stres, sarcină, dar şi în patologii: hipertiroidism, infarct miocardic, trombembolia arterei pulmonare, infecţii, anemie, hemoragii, nevroze etc. La gravide ritmul cardiac creşte cu peste 25%, astfel, TS, în special în al treilea trimestru, atinge o incidenţă de peste 50% (aritmie non-durabilă), iar tahicardia susţinută are o frecvenţă mai joasă – 2 - 3 la 1000 însărcinate. Prezentăm cazul clinic al parturientei de 28 ani cu TS manifestată clinic şi electrocardiografic, cu răspuns adecvat la tratament administrat

SOLIDWORKS 3D PARAMETRIC MODELLING TECHNIQUE FOR ROOT CUTTING EQUIPMENT DECLINING GROWTH OF SHOOTS IN ORCHARDS

This work was focused, by using computer aided engineering application (SolidWorks) and structural simulation (SolidWorks SIMULATION), on obtaining a technical and economic strength indicator used in the analysis of metallic material choice from which is made active body large diameter disc knife type, that equips the technical equipment for soil tillage on trees row, while cuttings root for moderating growth of shoots and precision foliar fertilization. For this purpose, on the 3D parametric modeling were selected from the software library various metallic materials, followed by finite element analysis (FEA) which was carried out to simulate the distributions of stress and strain on the body active. Based on the resulting data, were determined the reports price- coefficient of resistance for the materials analyzed. Comparing these indicators led to the selection of a material that has high resistance under a price as low as possible. Analysis based on technical and economic choice of a metallic material reduces the time validation of the design, by eliminating the realization and physical testing, and allows management to determine the existing resources in the company in order to use their total for achieve economic and financial results as high

THE GLASSWARE FROM MĂLĂIEȘTI ROMAN FORT AND BATH

Excavations at Mălăiești Roman Fort and bath (Romania, Prahova County) undertaken in 1930, 1954, 1985, and 2011-2019 revealed a small roman fortification and its baths, between 101-118 AD. This paper will attempt to show the significance of the glassware finds through a social-cultural analysis resulting from the way the finds were distributed within the site. Our study describes the glassware fragments found during recent excavations and offers an analysis in the context of the manufacturing processes, spatial distribution, and the circumstances of their discovery as well as the chemical analysis of the typical samples. As an end result, we were able to determine their chronological, morphological, and typological properties
