The hematopoietic stem cell (HSC) is postulated to be the ultimate hematopoietic precursor providing production of mature blood cells, and is characterized by a life long capacity for self-renewal and multilineage differentiation. In a healthy human, the HSC produces 1,000,000,000,000 cells per day, illustrating the high turnover within the hematopoietic system and the need for replenishments by H

Windows in a package is a common way to promote the product. The possibility to predict the collapse load for these types of cartonboard packages is considered. It is shown that reliable estimates of the collapse loads can be obtained by a very simple approach. This approach is a straightforward generalization of the proposal by Ristinmaa et al. (2012): for a side that contains a window, one simpl

Objective . Salivary cortisol is widely used in occupational health research. However, many ordinary daily activities can influence the concentrations of cortisol and the interpretation of field studies. The aim of the present study was to evaluate the effect of lifestyle factors on salivary cortisol in everyday settings. Material and methods . Healthy employees participated in one or more sub-stu

This study investigates the effects that public sector reforms had in the cultural field in European countries over the past two decades. The study highlights changing conditions for public/nonprofit management due to governance and public sector reforms. It does so by applying a multidisciplinary literature survey methodology, which is rare in management studies. The literature survey identifies

The globular protein γB-crystallin exhibits a complex phase behavior, where liquid-liquid phase separation characterized by a critical volume fraction ϕc = 0.154 and a critical temperature Tc = 291.8 K coexists with dynamical arrest on all length scales at volume fractions around ϕ ≈ 0.3-0.35, and an arrest line that extends well into the unstable region below the spinodal. However, although the s

Abstract in UndeterminedParticipatory media are commonly used in today's society for a variety of purposes. The credibility associated with these media is sometimes contested, and their acceptance into school practices has been debated. Focus group interviews with teachers and librarians in upper secondary schools in Sweden are used to investigate conceptions and experiences of activities involvin

Granular GaAs:(Mn,Ga)As films were prepared by annealing at 500 degrees C under ambient and enhanced hydrostatic pressure (1.1 GPa), of Ga1-xMnxAs/GaAs layers (x = 0.025, 0.03, 0.04, 0.05 and 0.063) grown at 230 degrees C by molecular beam epitaxy method. Distinct influence of enhanced hydrostatic pressure applied during sample annealing on strain state of inclusions was found. An increase of latt

In a previous paper, an approximate model for the contact between a rubber covered roller and a rigid roller was developed as analytical functional relationships connecting geometric parameters and material properties of the rubber to nip properties such as maximum contact pressure, etc. in a two-dimensional relationship. The results from that development are used in this work, with the objective

The coiled-coil protein DivIVA is a determinant of apical growth and hyphal branching in Streptomyces coelicolor. We have investigated the properties of this protein and the involvement of different domains in its essential function and subcellular targeting. In S. coelicolor cell extracts, DivIVA was present as large oligomeric complexes that were not strongly membrane associated. The purified pr

The Fms-like tyrosine kinase 3 (FLT3) mutation, especially FLT3- internal tandem duplications (FLT3-ITD), is common in AML and associated with poor prognosis and resistance to therapy. This study explores an alternative approach by investigating the role of MicroRNA-155 (miR-155) in AML, known for its oncogenic properties. Previous research has linked miR-155 to poor AML prognosis, particularly in

Several, studies have shown the effect diet can have on brain function and metabolism, and it is widely acknowledged that rodents exposed to diets rich in fat develop brain dysfunction. The causes are related to fat-induced neuroinflammation, glucose neurotoxicity, and reduced insulin signaling, which affect brain structure and function, resulting in behavioral and cognitive changes. Recent studie

Biometric fingerprint recognition is a cornerstone of modern authentication systems, yet conventional convolutional neural network approaches often struggle with challenging cases, subjected to noise and partial overlap. This thesis explores the potential of transformer-based architectures to address these challenges. We design, implement, and evaluate five models on a large-scale dataset of over

Brottsbekämpande myndigheter står inför allvarliga prövningar till följd av den gränsöverskridande organiserade brottsligheten. Detta har resulterat i en ambition om effektivisering av brottsbekämpningen, inte minst genom okonventionella utredningsmetoder som provokativa åtgärder. Betydelsen av det internationella straffrättsliga samarbetet har dessutom ökat. Brottsbekämpningen och samarbetet centLaw enforcement authorities are facing serious challenges as a result of cross-border organized crime. This has resulted in an ambition to make law enforcement more effective, not least through unconventional investigative methods such as provocative measures. The importance of international criminal justice cooperation has also increased. Law enforcement and cooperation often focus on encrypted c
