Purpose: Age and etiology play a crucial role in success of endoscopic third ventriculostomy (ETV) as a treatment of obstructive hydrocephalus. Outcome is worse in infants, and controversies still exist whether ETV is superior to shunt placement. We retrospectively analyzed 70 patients below 2 years from 4 different centers treated with ETV and assessed success. Methods: Children < 2 years who rec

GaN nanowires are potential candidates for use in scanning probe microscopy due to their well-defined, reproducible, geometric shapes, their hardness, and their light guiding properties. We have developed and investigated probes for high resolution atomic force microscopy and scanning tunneling microscopy utilizing GaN nanowires as probes. The nanowires are n-doped and the morphology of the nanowi

We have developed an electrochemical cell for in situ 2-Dimensional Surface Optical Reflectance (2D-SOR) studies during anodization and cyclic voltammetry. The 2D-SOR signal was recorded from electrodes made of polycrystalline Al, Au(111), and Pt(100) single crystals. The changes can be followed at a video rate acquisition frequency of 200 Hz and demonstrate a strong contrast between oxidizing and

A reduced VAT rate can apply to works of art. However, the definition of art for this beneficial treatment can differ from the art definition experts use. This is especially the case with regard to photographs. The central question in this article is whether this different view can be based on inherent characteristics of VAT as the ECJ claims. In order to answer this question, the article starts w

Background: Photoacoustic (PA) imaging is an emerging non-invasive biomedical imaging modality that could potentially be used to determine the borders of basal cell carcinomas (BCC) preoperatively in order to reduce the need for repeated surgery.Methods: Two- and three-dimensional PA images were obtained by scanning BCCs using 59 wavelengths in the range 680-970 nm. Spectral unmixing was performed

De små gårdarna är allvarligt hotade och därmed också mosaiklandskapet och den gastronomiska mångfalden. Det skriver flera debattörer.

One of the factors that can contribute to the resolution of long, doped inorganic scintillators used for nuclear spectroscopy is the variation of the dopant concentration over the length the detector crystal. In this work an investigation of such potential variations in one of the CsI(Tl) scintillators used in the calorimeter, CALIFA, of the R3B experiment at FAIR, has been performed using particl

Under de senaste åren har stora resurser lagts på forskning kring utvecklingen av biomaterial för ersättning av fossil-baserade material. Förpackningsindustrin i synnerhet är en sektor känd för att generera enorma mängder fast avfall, med produkter som inte sällan har betydligt kortare livslängd än sina materialkomponenter. Polylaktid (PLA) är en mångsidig biopolymer som används kommersiellt föIn recent years, large efforts have been put into the research of biomaterial synthesis for the replacement of fossil-based materials. Particularly in the packaging industry, a sector responsible for generating enormous amount of solid waste in which products have a considerably shorter life span than their material components. Polylactic acid (PLA) is a versatile, commercial biopolymer used fo

The purpose of this paper is to predict the cost-effectiveness of a preventive health care project based on physical exercise that will take place at Medicon Village, Lund, in the fall of 2016. Data from the Health Survey for England is used to develop an empirical model with individual fixed effects that estimates the relationship between physical exercise and psychological well-being. The freque

Thymidine kinase 1 from tomato (ToTK1) is a newly discovered deoxyribonucleoside kinase (dNK) that has been subject to study due to its in vitro and in vivo properties making it an interesting suicide gene candidate for the treatment of brain tumors. The ToTK1 phosphorylates the nucleoside analogue 3-azido-2,3-dideoxythymidine (azidothymidine, AZT) equally well as its natural substrate thymidine (

In the present study, the enzyme thymidine kinase 1 from tomato (ToTK1) was expressed in E.coli and purified to near homogeneity by means of affinity chromatography. However, purified ToTK1 of bacterial origin displayed no substantial catalytic activity. Expression was also attempted in insect cells using the baculovirus expression vector system (BEVS). Significant TK activities were detected in t

The relationship between business cycles and mortality has been a highly debated subject in the field of economics. The majority of previous studies, using the unemployment rate as the main proxy for macroeconomic conditions, have found ambiguous effects largely depending on how the effect is estimated. This thesis follows the methodology used by Ruhm (2000), but instead applies aggregate data for

This thesis covers specification and development of a distributed measurement system intended for CAN bus. It was completed at Scania CV, Södertälje in collaboration with Lund University. The goal of the thesis is to specifiy and develop a distributed measurement system that helps Scania with acquisition of functional and electrical data. Several topics are adressed such as filtering, at what spee

The purpose of this thesis was to study language transfer from the majority language Swedish to the minority language Arabic (the Syrian-Palestinian dialect). The problem negative language transfer causes is that dominant languages affect minority languages in a society in a negative way. The result is that the speakers of these languages never learn how to speak these languages properly. If we kn

Designing and developing a software product is a difficult process. The product must be usable and solve the correct problem. At the same time, the underlying code must be well written. Many projects fail to deliver or exceed their budget. This thesis explores a practical approach to software design and development that tries to adhere to both user centered design and agile development. The proces

In gas turbine blade modeling a stable but yet flexible method of describing the blade shape is crucial. Polynomials and B ́ezier curves have previously been used and in this paper B-splines are employed instead. This method removes the need for many of the interior derivative conditions on the curve but special care must be taken when selecting the parameter values and appropriate derivative cond

The wide and increasing range of screen sizes between Android devices makes consumers use them very differently. Large devices (like televisions) are more suitable to view content and smaller devices (like smart watches) are to be used more as a quick controller of the main application. Distributed user interfaces is the concept of utilizing several of these de- vices in one application, so that e
