Longitudes, Syzygies, and Instruments in Regiomontanus' Calender for 1475-1531

Instruments and tables in Regiomontanus’ calendar published in 1474 are analysed and explained. It is shown that Regiomontanus used the Alfonsine Tables corrected for the longitude time difference between Toledo and Nuremberg. It is also shown that for the syzygy and eclipse times he used apparent solar times. The syzygy tables of George Peurbach may have been used to correct from mean to true syz

Four Instruments in Martín Cortés' Breve Compendio de la Sphera and a Rule for Finding the Age of the Moon

This paper investigates and discusses four instruments found in a sixteenth century Spanish book of navigation. The night clock is a rather standard application of similar instruments known since the fourteenth century in Europe. Cortés’ explanation of the causes of the deviation of the magnetic and geographical north is quite original. His instrument to correct for that the Polaris deviates from

Forehead flap perfusion monitored by laser speckle contrast imaging – importance of flap length and thickness

Purpose: Forehead flaps are commonly used in oculoplastic surgery to cover defects after tumor excision. Blood perfusion is vital for flap survival. The aim of this study was to monitor the perfusion in forehead flaps and investigate the impact of flap length and thickness. Methods: Nineteen forehead flaps in patients undergoing direct brow lift were studied. Perfusion was monitored using laser sp

Home ranges, directionality and the influence of moon phases on the movement ecology of Indian flying fox males in southern India

Flying foxes of the genus Pteropus are amongst the largest fruit bats and potential long-range pollinators and seed dispersers in the paleotropics. Pteropus giganteus (currently P. medius) is the only flying fox that is distributed throughout the Indian mainland, including in urban and rural areas. Using GPS telemetry, we mapped the home ranges and examined flight patterns in P. giganteus males ac

Effects of Food Availability on Population Density; a Long-term Study of Wild Great Reed Warblers (Acrocephalus arundinaceus)

Food availability is known to influence animal distribution and abundance, playing a crucial role in population dynamics. However, this correlation remains somewhat unclear due to interactions with several other factors such as climate, predation pressure, competition, or even human influence. Therefore, understanding the mechanisms underlying these processes is crucial for ecologists to effective

Case studies using genealogical junctions among unplaced DNA matches to identify unknown ancestors.

The present paper describes case studies where the purpose was to identify two unknown ancestors: the author’s paternal grandfather [FF] and his paternal grandmother’s maternal grandfather’s father [FMMFF]. A four-step method was used: (1) The author’s and his brother’s closest atDNA matches were identified, and the genealogical relationships to these matches were searched for by a comparison with

Reforms and coalition building around the reindeer pastoralism of the Indigenous Sámi people in Sweden, 2012–2022

In Sweden, Indigenous Sámi reindeer pastoralists must find effective ways to improve ecological conditions conducive to natural pasture-based reindeer pastoralism in a rapidly changing environment. In particular, they must challenge the conventional climate policy agenda of the dominant economic and political actors. This paper seeks to contribute to the emergence of a social movement that can pus

Effect of silicone oil versus gas tamponade on macular layer microstructure after pars plana vitrectomy for macula on rhegmatogenous retinal detachment

Purpose: To analyze structural changes in the macular retinal layers and sub-foveal choroidal thickness (SFCT) in eyes after macula-on rhegmatogenous retinal detachment (RRD) repair by pars plana vitrectomy with either silicone oil (SO) or gas tamponade, and the effect of these changes on visual acuity. Patients and methods: Retrospective study which included 26 eyes in the SO Group and 32 in the

All that glitters is not gold : The depoliticization of social inequality in European education policy on ‘microcredentials’

At the present conjuncture of political, economic, social, and ecological crises, it is important to pay attention to the ways in which intensifying demands for equality, sustainability and social inclusion are met in education policy. In this article, we present results from a critical discourse analysis of an EU council recommendation on ‘microcredentials’ – credits for short courses primarily o

Enhanced LWIR response of InP/InAsP quantum discs-in-nanowire array photodetectors by photogating and ultra-thin ITO contacts

Here we report on an experimental and theoretical investigation of the long-wavelength infrared (LWIR) photoresponse of photodetectors based on arrays of three million InP nanowires with axially embedded InAsP quantum discs. An ultra-thin top indium tin oxide contact combined with a novel photogating mechanism facilitates an improved LWIR normal incidence sensitivity in contrast to traditional pla

Skewness and kurtosis of mean transverse momentum fluctuations at the LHC energies

The first measurements of skewness and kurtosis of mean transverse momentum (〈pT〉) fluctuations are reported in Pb–Pb collisions at sNN = 5.02 TeV, Xe–Xe collisions at sNN = 5.44 TeV and pp collisions at s=5.02 TeV using the ALICE detector. The measurements are carried out as a function of system size 〈dNch/dη〉|η|

A phylogenetic framework of Palaearctic and Indomalayan Limacodidae (Lepidoptera, Zygaenoidea) based on sequence capture data

The slug moth family Limacodidae is a cosmopolitan group of economic importance, but its higher level systematics remains poorly understood. Here, we present a robust, higher level phylogenetic framework for Palaearctic and Indomalayan members of the family using sequence capture data of 148 nuclear protein-coding and 13 mitochondrial markers from 145 samples of 126 species in 67 genera representi

Population dynamics of dominant dinoflagellate species in the North Sea : in situ growth rates, photosynthetic potential, and losses due to parasitism

In the North Sea, Tripos and Dinophysis are commonly occurring mixotrophic planktonic dinoflagellate genera. In order to understand their bloom dynamics, an occurring bloom dominated by T. furca and D. norvegica was followed for several days. High cell abundances of these species were located to estimate: in situ growth rates from cell cycle analyses, depth distributions, growth rates sustained by

Landscapes of risk : A comparative analysis of landscape metrics for the ecotoxicological assessment of pesticide risk to bees

Pesticide use in agricultural landscapes creates environmental contamination that is heterogenous in space and time. Mobile organisms, such as bees, are exposed to multiple contamination sources when visiting patches that vary in the amount, timing and toxicity of pesticides used. Yet, environmental risk assessments (ERA) typically fail to consider this heterogeneity, in part because of the comple

The crisis in psychological science, and the need for a person-oriented approach

The purpose of the present chapter is to discuss whether psychological science today is in a state of crisis, and if so how that crisis is to be characterized. Three aspects of a possible crisis are discussed: a replicability crisis, a normativity crisis, and a validity crisis. It is argued that the present crisis goes deeper than being merely a replicability crisis. There are also signs of a norm

Exertional breathlessness related to medical conditions in middle-aged people : the population-based SCAPIS study of more than 25,000 men and women

Background: Breathlessness is common in the population and can be related to a range of medical conditions. We aimed to evaluate the burden of breathlessness related to different medical conditions in a middle-aged population. Methods: Cross-sectional analysis of the population-based Swedish CArdioPulmonary bioImage Study of adults aged 50–64 years. Breathlessness (modified Medical Research Counci

Monitoring the Intracellular Fate of Molecular Beacons : The Challenge of False Positive Signals

Molecular beacons (MBs) have been used on surfaces for detecting oligonucleotides. Attempts to use them intracellularly for monitoring mRNA content have been made, however, without any clear conclusion regarding the reliability of the method, mainly due to false positive signals. To reach an understanding of the intracellular fate of MBs, a critical question remains: how long after MB delivery and

Mental and physical health in children of women with a history of anorexia nervosa

Few studies have investigated the offspring of women with anorexia nervosa (AN). The aim of this study was to examine perinatal status, mental and physical health in the offspring of mothers with a history of AN. Fifty-one individuals with adolescent-onset AN and 51 matched controls (COMP) have been followed prospectively. Presently, 30 years after AN onset, at a mean age of 44 years, female parti
