In situ detection of cancerous kidney tissue by means of fiber ATR-FTIR spectroscopy

The crucial goal of kidney-sparing surgical resection of a malignant tumor is complete removal of the cancerous tissue. The exact border between the cancerous and normal tissues is not always possible to identify by naked eye, therefore, a supplementary intraoperative diagnosis is needed. Unfortunately, intraoperative pathology methods used nowadays are time consuming and of inadequate quality ren

Assignment of vibrational spectral bands of kidney tissue by means of low temperature SERS spectroscopy

Surface enhanced Raman scattering (SERS) spectroscopy is a useful method for detection of trace amounts of molecules. It has already been successfully implemented for detection of explosives, food additives, biomarkers in blood or urine, etc. In the last decade, SERS spectroscopy was introduced into the field of health sciences and has been especially focused on early disease detection. In the rec

High-Definition Nanoimprint Stamp Fabrication by Atomic Layer Etching

ABSTRACT: Nanoimprint lithography (NIL) has the potential for low-cost andhigh-throughput nanoscale fabrication. However, the NIL quality and resolution areusually limited by the shape and size of the nanoimprint stamp features. Atomiclayer etching (ALE) can provide a damage-free pattern transfer with ultimate etchcontrol for features of all length scales, down to the atomic scale, and for all fea

Synchrotron X-ray based characterization of technologically relevant III-V surfaces and nanostructures

Populärvetenskaplig sammanfattning:En studie publicerad av NASA:s Goddard Institute for Space Studies år 2019 visade att de genomsnittliga globala temperaturerna under de senaste fyra åren (2015-2018) var de högsta som någonsin registrerats i människans historia. Den nyheten passar väl in i de alarmerande prognoserna om global uppvärmning, och kräver snabba och radikala handlingar. Att studera “teInnovative design and materials are needed to satisfy the demand for efficient and scalable devices for electronic and opto-electronic applications, such as transistors, LEDs, and solar cells. Nanostructured III-V semiconductors are an appealing solution, combining the excellent functional properties of III-V materials with the flexibility typical of nanostructures, such as the nanowires (NWs) stu

Genome-wide interaction and pathway-based identification of key regulators in multiple myeloma

Inherited genetic susceptibility to multiple myeloma has been investigated in a number of studies. Although 23 individual risk loci have been identified, much of the genetic heritability remains unknown. Here we carried out genome-wide interaction analyses on two European cohorts accounting for 3,999 cases and 7,266 controls and characterized genetic susceptibility to multiple myeloma with subsequ

Acoustofluidic preparation of whole blood components

Whole blood is rich in information about the physical state of an individual and is routinely used in a variety of clinical and research applications. In this thesis, the use of a microfluidic technique called acoustophoresis for separation of different blood components is explored. Acoustophoresis uses an ultrasonic standing wave field to manipulate cells in a microfluidic device. Cells within th

Different Visual Weighting due to Fast or Slow Vestibular Deafferentation : Before and after Schwannoma Surgery

Background: Feedback postural control depends upon information from somatosensation, vision, and the vestibular system that are weighted depending on their relative importance within the central nervous system. Following loss of any sensory component, the weighting changes, e.g., when suffering a vestibular loss, the most common notion is that patients become more dependent on visual cues for main

Factors influencing local attitudes towards the conservation of leopard cats Prionailurus bengalensis in rural Taiwan

Understanding the human dimension is critical for effective conservation management of species involved in human-carnivore conflict. There is also a need to recognize who among the local human population is supportive of wildlife conservation. We investigated how local people's attitudes and knowledge of the leopard cat Prionailurus bengalensis are influenced by socio-demographic variables, encoun

Phosphorus and Potassium Metasomatic Enrichment in the Mantle Source of the c. 1450-1425 Ma Michael-Shabogamo Gabbro of Eastern Laurentia

A c. 1450 Ma, east-west-oriented suite of Proterozoic mafic intrusions in eastern Canada, located between Labrador City and coastal Labrador near Rigolet, has been divided into two groups: the Shabogamo Gabbro, which is exposed west of Churchill Falls, and the Michael Gabbro, which crops out east of Churchill Falls. Both suites of gabbro are within-plate tholeiites that range from sub-alkaline bas

Measuring scientific productivity in China using malmquist productivity index

This paper aims to investigate the scientific productivity of China's science system. This paper employs the Malmquist productivity index (MPI) based on Data Envelopment Analysis (DEA). The results reveal that the overall efficiency of Chinese universities increased significantly from 2009 to 2016, which is mainly driven by technological progress. From the perspective of the functions of higher ed

Continuous-flow LVADs in the Nordic countries : complications and mortality and its predictors

Objectives: The purpose of this study was to assess complications and mortality and its predictors, with continuous-flow left ventricular assist devices (CF-LVADs) in the Nordic Countries. Design: This was a retrospective, international, multicenter cohort study. Results: Between 1993 and 2013, 442 surgically implanted long-term mechanical assist devices were used among 8 centers in the Nordic cou

Paleoenvironmental proxies and what the Xiamaling Formation tells us about the mid-Proterozoic ocean

The Mesoproterozoic Era (1,600–1,000 million years ago, Ma) geochemical record is sparse, but, nevertheless, critical in untangling relationships between the evolution of eukaryotic ecosystems and the evolution of Earth-surface chemistry. The ca. 1,400 Ma Xiamaling Formation has experienced only very low-grade thermal maturity and has emerged as a promising geochemical archive informing on the in

Dimension Engineering of High-Quality InAs Nanostructures on a Wafer Scale

Low-dimensional narrow-band-gap III-V semiconductors are key building blocks for the next generation of high-performance nanoelectronics, nanophotonics, and quantum devices. Realizing these various applications requires an efficient methodology that enables the material dimensional control during the synthesis process and the mass production of these materials with perfect crystallinity, reproduci

Environmental effects on flying migrants revealed by radar

Migratory animals are affected by various factors during their journeys, and the study of animal movement by radars has been instrumental in revealing key influences of the environment on flying migrants. Radars enable the simultaneous tracking of many individuals of almost all sizes within the radar range during day and night, and under low visibility conditions. We review how atmospheric conditi

Innovation Policies and New Regional Growth Paths : A Place-Based System Failure Framework

Fundamental and enduring changes brought about by recurrent economic and financial crises, the digital revolution and ongoing globalisation processes of production and innovation activities are posing major challenges for regional and national economies to renew their industrial structures and develop innovations that break existing development trajectories. This calls for new innovation policy ap

Dignity and displaced Syrians in Lebanon. ‘There is no karama here’

Since the popular uprising and subsequent war in Syria in 2011, more than a quarter of its population have fled – mainly to Turkey, Lebanon, Jordan, Iraq and Egypt – and another 25% have been internally displaced. The end of 2017 saw 12.6 million Syrians forcibly displaced – 6.3 million refugees, 6.2 million internally displaced (IDPs) and 146,700 asylum-seekers. In the words of the United Nations

Protecting the dignity of displaced Syrians

What does dignity mean to Syrian refugees and practitioners? And what can humanitarian organisations do – or abstain from doing – to help Syrians preserve and protect their dignity?

Funding to Syrian Humanitarian Actors. Between sub-contracting and partnership

A new report from L2GP estimates, that while Syrian humanitarian actors were responsible for delivering 75% of the humanitarian assistance in 2014, they received only 0.3% of the direct and 9.3 % of the indirect cash funding available for the overall Syria response. Despite their crucial role, Syrian NGO’s struggled to get their most basic costs covered in the sub-contracting and partnership agree
