Development of an Isoline Modeling Method for Extended Small Celestial Objects

Учёные записки Казанского университета: Серия Физико-математические науки
This article presents a method for modeling extended small celestial (ESC) objects, which are mainly cometary systems. Special attention was given to the possibility of analyzing their structure and physical properties in line with the modern theories of

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

Environmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The

Postperihelion Cometary Activity on the Outer Main-belt Asteroid 2005 XR132

The Planetary Science Journal
We report comet-like activity on the outer main-belt asteroid 2005 XR _132 discovered by the Lulin One-meter Telescope in early 2021 April. A series of follow-up observations were triggered to characterize the morphology and brightness variation of 2005 ...

Thermal Evolution of the Nucleus of the Comet 67P for 120 Years: Numerical Simulations

Open Astronomy, 2018
The purpose of this paper is to estimate to what temperatures and to what depth the outer layers of the cometary nuclei are heated for several dozen revolutions around the Sun, and what changes in the composition of the volatiles occur in this case. This

A core outcome set and reporting checklist for research on critically ill obstetric patients: An international consensus study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
An international, multi‐method consensus process identified 10 core outcomes, 7 reporting items, and 4 noncore outcomes to standardize outcome reporting, reduce heterogeneity, and improve comparability and patient‐centeredness of research on critically ill obstetric patients.

Doublecortin restricts neuronal branching by regulating tubulin polyglutamylation

Nature Communications
Doublecortin is a neuronal microtubule-associated protein that regulates microtubule structure in neurons. Mutations in Doublecortin cause lissencephaly and subcortical band heterotopia by impairing neuronal migration. We use CRISPR/Cas9 to knock-out the

What can lithics tell us about food production during the transition to farming? Exploring harvesting practices and cultural changes during the neolithic in Southwest Asia: a view from Qminas (north‐western Syria)

Archaeometry, EarlyView.
Abstract This study examines the continuity and change in harvesting practices between the Late Pre‐Pottery Neolithic B (LPPNB) and the Early Pottery Neolithic at Qminas, north‐western Levant, through a traceological analysis of flint sickles. By combining qualitative traceological analysis with quantitative functional approaches, we demonstrate that ...

Older Adults' Self‐Care and Family Caregiver Contribution in Multiple Chronic Conditions: A Dyadic Qualitative Study

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aims To explore how older adult‐family caregiver dyads jointly manage multiple chronic conditions. Specifically, it investigates how dyads (i) prioritise chronic diseases, (ii) make and negotiate decisions related to self‐care and (iii) define and distribute self‐care tasks and caregiver contributions.

Analysing Resilience Indicator Traits in Austrian Fleckvieh, Brown Swiss and Holstein‐Friesian Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Recent studies suggest that variations in milk yield during lactation can serve as a metric for assessing individual resilience, with minimum fluctuations reflecting greater resilience in cows. With automatic milking systems, multiple records can be obtained from many cows on a daily basis. Given that animals are continually exposed to a range
