Is the solar spectrum latitude dependent? An investigation with SST/TRIPPEL
Context: In studies of the solar spectrum relative to spectra of solar twin
stars, it has been found that the chemical composition of the Sun seems to
depart systematically from those of the twins. One possible explanation is that
the effect is due to the special aspect angle of the Sun when observed from
Earth, as compared with the aspect angles of the twins. Thus, a latitude
dependence of the solar spectrum, even with the heliocentric angle constant,
could lead to effects of the type observed.
Aim: We explore a possible variation in the strength of certain spectral
lines, used in the comparisons between the composition of the Sun and the
twins, at loci on the solar disk with different latitudes but at constant
heliocentric angle.
Methods: We use the TRIPPEL spectrograph at the Swedish 1-m Solar Telescope
on La Palma to record spectra in five spectral regions in order to compare
different locations on the solar disk at a heliocentric angle of 45 deg.
Equivalent widths and other parameters are measured for fifteen different lines
representing nine atomic species.
Results: The relative variations in equivalent widths at the equator and at
solar latitude 45 deg are found to be less than 1.5 % for all spectral lines
studied. Translated to elemental abundances as they would be measured from a
terrestrial and a hypothetical pole-on observer, the difference is estimated to
be within 0.005 dex in all cases.
Conclusion: It is very unlikely that latitude effects could cause the
reported abundance difference between the Sun and the solar twins. The accuracy
obtainable in measurements of small differences in spectral line strengths
between different solar disk positions is very high.Comment: 9 pages, 10 figures, accepted by Astronomy & Astrophysic
A longitudinal study on maternal depressive symptoms during the COVID-19 pandemic: the role of strict lockdown measures and social support
Objectives: This study examined the trajectory of perinatal depressive symptoms in Portuguese women during the COVID-19 pandemic and the role of individual, relational, and contextual risk and protective factors. Methods: This 3-wave longitudinal study followed 290 pregnant women from the third trimester of pregnancy until 6-months postpartum. Women self-reported on depressive symptoms, psychological (anxiety, perceived stress, mindfulness), relational (perceived social support, dyadic adjustment, sexual wellbeing), and contextual (lockdown status) factors. Results: Women who were under strict lockdown presented significantly higher scores of depressive symptoms at baseline (by 1.38 EPDS points) than women who were not under strict lockdown measures. Mixed Growth Models showed that trajectories of depressive symptoms were explained by differences in women’s baseline depression. Differences in women’s depressive symptoms at baseline were mainly explained by higher anxiety and lower social support (22% and 24% for women under lockdown; 39% and 6% for women not on lockdown, respectively). Conclusion: Preventative interventions targeted at pregnant women should aim to reduce anxiety and enhance women’s social support to prevent depression in pregnancy and postpartum during the COVID-19 pandemic

СРК сочетающаяся с нейроциркуляторной дистонией: воспаление, клиническое течение, эффективность лечения
Проведено дослідження показників у хворих на СРК, що характеризують
запалення й зв’язки їх з наявністю нейроциркуляторної дистонії. У хворих на СРК із
наявністю супутньої НЦД має місце достовірне підвищення інтенсивності
запалення, про що свідчать підвищені середні рівні СРБ та інтерлейкіну-8, а також
питома вага осіб з більш високими їхніми концентраціями. Установлено
достовірний взаємозв’язок величини індексу Кердо зі ступенем важкості СРК,
інтенсивністю ряду клінічних і психологічних показників, а також рівнем СРБ,
інтерлейкіну-8. Установлено достовірну кореляцію наявності НЦД із концентрацією
С-реактивного білка, IL-8.The article represents a study of indicators of inflammation and their relation to the
presence of neurocirculatory dystonia in patients with IBS. Patients with IBS and
associated NCD have a definite increase of inflammation intensity, this is indicated by
higher average levels of CRP and interleukin-8, as well as the proportion of persons
with higher concentrations. A reliable value of the Kerdo index relationship with the
gravity of the IBS, intensity of a number of clinical and psychological indicators, as well
as the level of CRP, interleukin-8 has been found. Also, a definite correlation with the
presence of NCD with concentration of Creactive protein, IL-8 has been established
