A New Method for Endoscopic Sampling of Submucosal Tissue in the Gastrointestinal Tract : A Comparison of the Biopsy Forceps and a New Drill Instrument

Background. Sampling of submucosal lesions in the gastrointestinal tract through a flexible endoscope is a well-recognized clinical problem. One technique often used is endoscopic ultrasound-guided fine-needle aspiration, but it does not provide solid tissue biopsies with preserved architecture for histopathological evaluation. To obtain solid tissue biopsies from submucosal lesions, we have const

Impact of urban water supply on energy use in China : a provincial and national comparison

To reduce greenhouse gas (GHG) emissions and help mitigate climate change, urban water systems need to be adapted so that electrical energy use is minimised. In this study, energy data from 2011 was used to quantify energy use in China’s urban water supply sector. The objective was to calculate the energy co-benefits of urban water conservation policies and compare energy use between China and oth

Book reviews 2016

This section contains reviews of two Swedish books on international taxation. First, the book Skatteavtal och generalklausuler, Ett komparativt perspektiv (TaxAgreements and General Anti-Avoidance Regulations, A Comparative Perspective) is recommended for those who study and work with international tax law. The book analyses how tax treaties function to limit contracting states’taxing powers relat

Novel insights from coleopteran and pollen evidence into the Lateglacial/Holocene transition in Aubrac, French Massif Central

The aim of this study is to describe the environmental and climate changes that occurred in the mountains of Aubrac at the transition between the Lateglacial and the Holocene, from a comparative analysis of fossil Coleoptera and pollen, and a series of 23 14C dates. The changes affecting the ecological categories of Coleoptera lead to a division of the sequence into 5 beetle assemblage zones (BAZ)

Ictal EEG source imaging in presurgical evaluation : High agreement between analysis methods

Purpose To determine the agreement between five different methods of ictal EEG source imaging, and to assess their accuracy in presurgical evaluation of patients with focal epilepsy. It was hypothesized that high agreement between methods was associated with higher localization-accuracy. Methods EEGs were recorded with a 64-electrode array. Thirty-eight seizures from 22 patients were analyzed usin

The genetic diversity, phylogeography and morphology of Elphidiidae (Foraminifera) in the Northeast Atlantic

Genetic characterisation (SSU rRNA genotyping) and Scanning Electron Microscope (SEM) imaging of individual tests were used in tandem to determine the modern species richness of the foraminiferal family Elphidiidae (Elphidium, Haynesina and related genera) across the Northeast Atlantic shelf biomes. Specimens were collected at 25 locations from the High Arctic to Iberia, and a total of 1013 indivi

Changes in El Niño – Southern Oscillation (ENSO) conditions during the Greenland Stadial 1 (GS-1) chronozone revealed by New Zealand tree-rings

The warming trend at the end of the last glacial was disrupted by rapid cooling clearly identified in Greenland (Greenland Stadial 1 or GS-1) and Europe (Younger Dryas Stadial or YD). This reversal to glacial-like conditions is one of the best known examples of abrupt change but the exact timing and global spatial extent remain uncertain. Whilst the wider Atlantic region has a network of high-reso

Regulating planned obsolescence: a review of legal approaches to increase product durability and reparability in Europe

Improving product durability and reparability can save natural resources and money for consumers but may not always be in the best interest of all manufacturers. With the emergence of the circular economy as an important policy objective in the European Union (EU), there is renewed interest in policies to promote durability and address planned obsolescence. Different legislative approaches are cur

Cholelithiasis during the first year of life : Case reports and literature review

Five cases are reported of children with gallstones diagnosed by ultrasound during their first 7 months of life. Of the four with symptomatic gallstones, one subsequently developed vitamin K deficiency syndrome with profuse bleedings. The children, who belonged to a defined population, were all diagnosed within an 18-month span, suggesting the frequency of early gallstone formation to be higher th

Riseberga Restoration Project

This project is designed as a typical consultancy work for Environmental Engineering students at the Faculty of Engineering (LTH), Lund University, Sweden. It gives students a feeling of a possible future work by being a practical training in solving a complex environmental problem involving hydrological and ecological challenges. Additionally, the project work provides training of critical thinki

An Intelligent Surveillance System

This paper presents the outline, goal, achievements,and work in progress of the hardware image processing projectat the Digital-ASIC group at Lund institute of technology (LTH).The project attempts to automate a surveillance system for indoormonitoring. This includes motion segmentation, image filtering,feature extraction, tracking, and classification. Hardware accel-erators for segmentation and f

Lipase-Mediated Syntheses of Trimethylolpropane-Based Biolubricant and Cyclic Carbonate

Popular Abstract in English Popular Summary Since the beginning of mankind, humans have managed to find ways to make use of the resources available at hand in order to survive and even to improve their livelihoods. The basic needs for food as well as other amenities were met from plant- and animal resources until the 19th century when industrial revolution changed the base of production to fossilAbstract Biocatalysis is considered as benign and efficient alternative to chemical catalysis for organic syntheses. Lipases are the most versatile biological catalysts implemented so far with great potential for production of different chemicals and materials in non-conventional reaction media. This thesis presents investigations on lipase catalyzed esterification and transesterification reaction
