Astronomical Distance Determination in the Space Age: Secondary Distance Indicators

The formal division of the distance indicators into primary and secondary leads to difficulties in description of methods which can actually be used in two ways: with, and without the support of the other methods for scaling. Thus instead of concentrating on the scaling requirement we concentrate on all methods of distance determination to extragalactic sources which are designated, at least formally, to use for individual sources. Among those, the Supernovae Ia is clearly the leader due to its enormous success in determination of the expansion rate of the Universe. However, new methods are rapidly developing, and there is also a progress in more traditional methods. We give a general overview of the methods but we mostly concentrate on the most recent developments in each field, and future expectations. © 2018, The Author(s)

Author Correction:Genetic effects on the timing of parturition and links to fetal birth weight (Nature Genetics, (2023), 55, 4, (559-567), 10.1038/s41588-023-01343-9)

Correction to: Nature Genetics. Published online 3 April 2023. In the version of this article originally published, the surname of author Stefan Johansson was misspelled as Johanson. In the abstract and “Genome-wide association analyses” section of the Results, the number of loci associated with preterm birth was shown as six instead of seven. In addition, there was a production error in the Figure 1a y-axis units shown below 0, where “10” and “20” were shown as negative numbers. The errors have been corrected in the HTML and PDF versions of the article.</p

Genetic effects on the timing of parturition and links to fetal birth weight

The timing of parturition is crucial for neonatal survival and infant health. Yet, its genetic basis remains largely unresolved. We present a maternal genome-wide meta-analysis of gestational duration (n = 195,555), identifying 22 associated loci (24 independent variants) and an enrichment in genes differentially expressed during labor. A meta-analysis of preterm delivery (18,797 cases, 260,246 controls) revealed six associated loci and large genetic similarities with gestational duration. Analysis of the parental transmitted and nontransmitted alleles (n = 136,833) shows that 15 of the gestational duration genetic variants act through the maternal genome, whereas 7 act both through the maternal and fetal genomes and 2 act only via the fetal genome. Finally, the maternal effects on gestational duration show signs of antagonistic pleiotropy with the fetal effects on birth weight: maternal alleles that increase gestational duration have negative fetal effects on birth weight. The present study provides insights into the genetic effects on the timing of parturition and the complex maternal–fetal relationship between gestational duration and birth weight.</p

Wpływ docisku kliszy fotopolimerowej, do podłoża podczas druku metodą flexograficzną, na wytrzymałość opakowań z tektury falistej

In the following article, an attempt was made to empirically determine an impact of technological errors on compression resistance of corrugated fiberboard transport containers during inline flexographic printing on industrial slotted - printing - gluing and folding machine. Investigation proves that the printing process has an influence on packaging resistance. It has been shown how important press photopolymer printing plates are to corrugated board adjustment by a machine operator and a correct production technology preparation. Adjusted high pressure due to male/female creasing occurred, caused resistance loss by 13%.Wpływ docisku kliszy fotopolimerowej, do podłoża podczas druku metodą flexograficzną, na wytrzymałość opakowań z tektury falistej. W niniejszym artykule podjęto próbę empirycznego sprawdzenie wpływu błędów technologicznych podczas druku metodą flexograficzną inline na przemysłowej maszynie slotująco - drukująco - klejącej na wytrzymałość na nacisk statyczny opakowań transportowych. Badania dowiodły, iż proces druku inline metodą flexograficzą ma wpływ na wytrzymałość opakowań. Wykazano również jak ważne jest optymalne ustawienie docisków kliszy do tektury przez drukarza oraz poprawne ustawienie technologii produkcji. Bigowanie obustronne wymusiło docisk powodujący spadek wytrzymałości rzędu 13%

Trikhomonadoznyje i drugie netrikhomonadoznye vospalitel'nye processy uretry u muzhchin

The authors examined 121 patients males with an effluvium from the urethra. They found in 66.1% of the cases a not-gonorrhoeal inflammation of the urethra. In 6.6% of all the cases of the inflammation of the urethra and 10% of the not-gonorrhoeal inflammations of the urethra were caused by Trichomonas vaginalis. In 1.7% of the cases of the total number of men with an effluvium from the urethra there coexisted the infection with diplococcus of Neisser and Trichomonas vaginalis
