We investigate the possibility that the Sun could have been born in M67 by carrying out N-body simulations of M67-like clusters in a time-varying Galactic environment, and following the Galactic orbits of stars that escape from them. We find that model clusters that occupy similar orbits to M67 today can be divided up into three groups, which we call hot, depleted, and scattered clusters. Hot clus

Obligately multicellular organisms, where cells can only reproduce as part of the group, have evolved multiple times across the tree of life. Obligate multicellularity has only evolved when clonal groups form by cell division, rather than by cells aggregating, as clonality prevents internal conflict. Yet obligately multicellular organisms still vary greatly in 'multicellular complexity' (the numbe

In this work, Piraíba and Dourada skin wastes were used for leather processing. They were initially stripped and characterized by their percentage composition. The results showed that pH, differential pH cipher [SLC13/ IUC 11/ BS 1309:9 - Determination of pH value and Difference Figure of an Aqueous Extract], chromium content and mechanical properties after chromium tanning were in accord with lea

This chapter introduces the research presented in the volume. It starts by highlighting the importance of an individual-level perspective to understand how long-term economic and societal changes connected with industrialization and post-industrialization have affected individuals and families during the twentieth century and into the twenty-first century as these changes pertain to social class,

Introduction: Atrial septal defect is the third most common CHD. A hemodynamically significant atrial septal defect causes volume overload of the right side of the heart. Preterm children may suffer from both pulmonary and cardiac comorbidities, including altered myocardial function. The aim of this study was to compare the rate of adverse events following atrial septal defect closure in preterm-

Plasma proteomics offers high potential for biomarker discovery, as plasma is collected through a minimally invasive procedure and constitutes the most complex human-derived proteome. However, the wide dynamic range poses a significant challenge. Here, we propose a semi-automated method based on the use of multiple single chain variable fragment antibodies, each enriching for peptides found in up

Platelets are megakaryocyte-derived cellular fragments lacking a nucleus and are classically known for their crucial role in supporting hemostasis. Besides their hemostatic function, it is becoming increasingly clear that platelets are much more diverse and that they are capable of a wide range of immune-sensing functions. This chapter will focus on these non-hemostatic immunological aspects, espe

Background: There is an increasing interest in shorter, proximally loading, uncemented femoral stems. The aim of this study was to evaluate a new short stem type, its design based on a well-proven precursor, but with several new design features to facilitate easier insertion and possible preservation of proximal bone stock. It is available with or without a collar. Methods: The study includes 50 p

The bacterial superantigen (SAg) staphylococcal enterotoxin A (SEA) is a potent inducer of CTL activity and cytokine production in vivo. To engineer SAg for cancer immunotherapy, we genetically fused SEA to a Fab fragment of the C215 tumor-reactive antibody. Strong reduction of lung metastasis was seen in mice carrying established lung metastases of the poorly immunogenic B16-C215 melanoma after F

This paper presents and discusses a method using a range of techniques for assessing sensorial perception of product design and interaction. Collectively denoted ‘Five Senses Testing’, the purpose of the method is to facilitate the assessment of sensory experience related to product design and product use. Furthermore, the outcomes of using the techniques inform product design development by conne

Noise control in buildings should aim at reducing disturbances caused by speech noise (i.e., improve speech privacy, speech intelligibility). Room acoustics can be controlled with high room absorption, high screens and bookcases, and sufficient masking sound. This research concerns as important aspect of room acoustic metrology, the ability to quantify the most relevant room acoustic parameters fo

Ice observations were made in the Rane River 1974-1978. Observations of formation of ice, growth of ice, critical velocities, hydrodynamic stability, supercooled water, ice production in rapids and breakup were theoretically analyzed. Depending on the water velocity an ice cover formed after 40-100 negative °C-degree-days. The growth of ice took place at a static growth when the water velocity was

The main objective of the current study is to apply a random forest (RF) data-driven model and prioritization of landslide conditioning factors according to this method and its comparison to a multivariate adaptive regression spline (MARS) model for landslide susceptibility mapping in China. For this purpose, at first, landslide locations were identified by earlier reports, aerial photographs, and
