Photocatalytic Degradation of Bacteriophages Evidenced by Atomic Force Microscopy

Methods to supply fresh water are becoming increasingly critical as the world population continues to grow. Small-diameter hazardous microbes such as viruses (20-100 nm diameter) can be filtered by size exclusion, but in this approach the filters are fouled. Thus, in our research, we are investigating an approach in which filters will be reusable. When exposed to ultraviolet (UV) illumination, tit

Numerical modeling of ship wave generation using Green’s functions based on linear dispersive wave theory

In this study, an efficient numerical model for predicting ship waves was developed using Green’s functions. Avoiding detailed description of the complex boundary conditions around a ship, this model simply used an inversion technique for estimating the wave source induced by a ship as a function of the navigation route and adjacent measured water level fluctuations. The Green’s functions were det

Linking war, natural resources and public revenues: the case of the War of the Pacific (1879-1883)

We argue that wars over natural resources, even if they are limited in their military scope, can have long-term consequences on the level and composition of public revenues. Military success in a resource war may lead to the annexation of natural resource-rich areas from enemy combatants, which provides the winning coalition with valuable and easy-to-tax sources of income. This, however, might dis

Perfusion weighted MR imaging may differentiate primary CNS-lymphoma from other homogeneously enhancing brain tumors.

Primary central nervous system lymphoma (PCNSL), glioblastoma multiforme (GBM) and metastases may be difficult to differentiate based on conventional imaging alone. The aim of this study was to investigate the value of perfusion weighted imaging (PWI) in differentiating homogeneously enhancing PCNSL from homogeneously enhancing GBM and metastases. Seven consecutive patients presenting with homogen

Ambipolar transport in narrow bandgap semiconductor InSb nanowires

We report on a transport measurement study of top-gated field effect transistors made out of InSb nanowires grown by chemical vapor deposition. The transistors exhibit ambipolar transport characteristics revealed by three distinguished gate-voltage regions: In the middle region where the Fermi level resides within the bandgap, the electrical resistance shows an exponential dependence on temperatur

Intensive Care Unit Delirium, Clinical Observations, and Patients' Statements : A Case Study

BACKGROUND: In clinical practice, nurses use their clinical gaze and make observations in order to assess patients' medical conditions and care needs. However, signs of developing intensive care unit delirium (ICUD) are often difficult to determine, as communication with patients is usually limited because of intubation and the seriousness of their medical condition(s). Usually, ICUD is screened a

Universiteten och de juridiska fakulteterna som remissinstanser

Kraven på beredning av lagstiftning är en central del i det svenska konstitutionella systemet. I ett större perspektiv kan man se dessa krav som ett uttryck för en mer allmän offentligrättslig princip om beredning av beslut. Mot denna bakgrund behandlar artikeln universitetens och de juridiska fakulteternas roll i lagberedningen som remissinstanser. Utifrån författarens erfarenheter lämnas några s

In recent years, parenting support has gained traction in the Swedish welfare state in both policy and practice. Parenting is seen as determining child outcomes and are thus in need of knowledge and expertise. Yet, at the same time, parents are conceptualised as experts of their own child. The intriguing paradox between parents being experts while at the same time being in need of parenting suppor

CSF levels of synaptosomal-associated protein 25 and synaptotagmin-1 in first-episode psychosis subjects

Post-mortem studies consistently show evidence of reduced synaptic protein levels in patients with schizophrenia. Clinically high-risk subjects show a steeper decrease in grey matter thickness and in vitro modeling using patient-derived cells implicate excessive synaptic pruning during neurodevelopment as a part of the schizophrenia pathophysiology. However, it is unclear to what extent synapse el

Effect of high voltage pulses on survival of Chinese hamster V79 lung fibroblast cells

The objective is to study the effect of high voltage pulses on living cells to find the most effective combination of physical parameters to be used in tumour therapy. Four parameters that affect the cell survival are the pulse shape, electric field strength, pulse length and the number of pulses and their cell killing effect were investigated in this work. High voltage square wave or exponentiall

Permeability of the blood‐brain barrier induced by 915 MHz electromagnetic radiation, continuous wave and modulated at 8, 16, 50, and 200 Hz

Biological effects of electromagnetic fields (EMF) on the blood‐brain barrier (BBB) can be studied in sensitive and specific models. In a previous investigation of the permeability of the blood‐brain barrier after exposure to the various EMF‐components of proton magnetic resonance imaging (MRI), we found that the exposure to MRI induced leakage of Evans Blue labeled proteins normally not passing t

Self-reactive T cells induce and perpetuate chronic relapsing arthritis

Background: CD4+ T cells play a central role during the early stages of rheumatoid arthritis (RA), but to which extent they are required for the perpetuation of the disease is still not fully understood. The aim of the current study was to obtain conclusive evidence that T cells drive chronic relapsing arthritis. Methods: We used the rat pristane-induced arthritis model, which accurately portrays

Proteolysis of Iron Oxide-Associated Bovine Serum Albumin

Proteins are a substantial nitrogen source in soils provided that they can be hydrolyzed into bioavailable small peptides or amino acids. However, the strong associations between proteins and soil minerals restrict such proteolytic reactions. This study focused on how an extracellular fungal protease (Rhizopus sp.) hydrolyzed iron oxide-associated bovine serum albumin (BSA) and the factors that af

Managing a Century of Debt

This paper provides a consistent series for the Irish national debt since the foundation of the state. It also provides a continuous series for bond yields over the same period. The paper examines the factors behind the fluctuations in the debt burden over almost a century. The management of the debt burden by the Irish authorities has evolved over time, seeking to minimise both the burden on the
