The dragon simulations: globular cluster evolution with a million stars

Introducing the dragon simulation project, we present direct N-body simulations of four massive globular clusters (GCs) with 106 stars and 5 per cent primordial binaries at a high level of accuracy and realism. The GC evolution is computed with nbody6++gpu and follows the dynamical and stellar evolution of individual stars and binaries, kicks of neutron stars and black holes (BHs), and the effect

Cataclysmic variables in globular clusters . First results on the analysis of the MOCCA simulations database

In this first investigation of the MOCCA database with respect to cataclysmic variables, we found that for models with Kroupa initial distributions, considering the standard value of the efficiency of the common-envelope phase adopted in BSE, no single cataclysmic variable was formed only via binary stellar evolution, i. e., in order to form them, strong dynamical interactions have to take place.

Formation mechanisms of IMBH in globular clusters

We very briefly discuss proposed in the literature possible scenarios for intermediate mass black holes formation in globular clusters. We also discuss the results of the MOCCA simulations of about 2000 models (BigSurvey) regarding the distribution of events connected with electromagnetic and gravitational radiations, namely: mass transfer on IMBH, collisions and mergers with IMBH and mergers with

MOCCA code for star cluster simulations - IV. A new scenario for intermediate mass black hole formation in globular clusters

We discuss a new scenario for the formation of intermediate mass black holes (IMBHs) in dense star clusters. In this scenario, IMBHs are formed as a result of dynamical interactions of hard binaries containing a stellar-mass black hole (BH), with other stars and binaries. We discuss the necessary conditions to initiate the process of intermediate mass BH formation and the influence of an IMBH on t

Potential difficulties during investigations due to solid state drive (SSD) technology

This paper discusses potential complications for Forensic Investigations due to the spread of Solid State Disc (SSD) technologies and influence of socio-technical factors. The discussion is drawing upon a study based on interviews with an experienced Forensic Investigator from Hampshire Constabularies Hi-Tech Crime Unit (HTCU), located in the United Kingdom. The goal of this study was to identify

Antibody immobilization strategy for the development of a capacitive immunosensor detecting zearalenone

A highly sensitive flow-injection capacitive immunosensor was developed for detection of the mycotoxin zearalenone (ZEN). Different strategies for immobilization of an anti-ZEN antibody on the surface of a gold electrode, i.e. polytyramine or self-assembled monolayers (SAMs) of 3-mercaptopropionic acid (3-MPA) and lipoic acid (LA), were used and their performances were compared. The LA- and 3-MPA-

Stepping on the cracks—transcending the certainties of big data analytics

Every aspect of modern life is dominated by decision-making and the availability of data. We constantly access, process and evaluate data as we navigate complex and uncertain problem spaces. Communication and Information Technologies (ICTs) have developed to a point where it is possible for very large data sets, measured in Exabyte, to be stored across many servers and gathered by many different p

The Economic Considerations of a Sustainable City Logistics-based Business Model

City logistics initiatives are often conceived as enablers to address the challenges related to the supply and disposal of goods in city centres. Several such city logistics initiatives have been tested to address these challenges. A majority of these initiatives have used urban consolidation centres to bundle deliveries within cities, and several of the initiatives include environmental zones, ac

Feeding and respiration

Coordination of breathing and swallowing is essential for normal bolus transportation through the pharynx and for protection of the airways. During passage of the bolus through the pharynx, respiration is interrupted. Normal swallowing occurs during the expiratory phase of breathing. Incoordination of the feeding respiratory pattern may lead to penetration of the bolus into the airways. This may c

The actual environmental effects for city logistics: a scenario analysis

Purpose City logistics projects often include urban consolidation centres (UCCs) to reduce the environmental impact of transportation by consolidating the goods flow in cities. However, there is limited knowledge about the actual environmental effects of such consolidation, e.g. in terms of number of vehicles in a city and the congestion, nuisances and emissions. The purpose of the paper is to mea

Inventory of best practices to prevent incursions into work zones - Literature review.

The aim of this report was to review the literature to identify existing best practices used to prevent incursions into work zones and improve safety of road users and road workers. A systematic literature search was conducted and various available sources referred to by knowledgeable experts in the field were considered. Best practices found in the literature review comprise both regulatory/manag

Turning vice into virtue : Using Batch-Effects to Detect Errors in Large Genomic Datasets

It is often unavoidable to combine data from different sequencing centers or sequencing platforms when compiling datasets with a large number of individuals. However, the different data are likely to contain specific systematic errors that will appear as SNPs. Here, we devise a method to detect systematic errors in combined datasetIs. To measure quality differences between individual genomes, we s

”Leder religionsantropologins utmaningar och forskningsproblematik till nostalgiska elegier och idylliska tankar om ädla vildar?”

Theology, religious studies, the history of religion, and the anthropology of religion have different histories as research disciplines, which explainsdifferences in how they pose research problems and define their research fields. In some respects, the disciplines have a lot in common and may cross-fertilize each other. In this article, I reflect on a theologian's critical review in Religionsvide
