Experimental study of heat transfer control around an obstacle by using a rib

This paper investigates the effect of the presence of a rib on the end-wall heat transfer of an obstacle by liquid crystal thermography. An obstacle with a rectangular cross section is placed in a rectangular channel and blocks the entire height of it (AR = 4). A rib with a square cross section is placed at two positions, i.e., in the upstream and downstream areas of the obstacle, respectively. An

Analysis of vortical structures in intermittent jets

The manipulation of jets has since long been subject to research, due to the wide range of industrial applications in which they are used. A vast number of numerical and experimental studies concerning the physics of the breakup process of continuous jets have been published. Improvements in mixing and ambient gas entrainment have been reported experimentally when using intermittent injection, alt

Association of serum MiR-142-3p and MiR-101-3p levels with acute cellular rejection after heart transplantation

Background: Identifying non-invasive and reliable blood-derived biomarkers for early detection of acute cellular rejection in heart transplant recipients is of great importance in clinical practice. MicroRNAs are small molecules found to be stable in serum and their expression patterns reflect both physiological and underlying pathological conditions in human. Methods: We compared a group of heart

The damping of transverse coherent instabilities by harmonic cavities

At nonzero chromaticity, the threshold current due to transverse coupled bunch instabilities in an electron storage ring is defined by intrabunch head-tail motion of higher than zeroth order. Multibunch tracking simulations predict that this threshold can be increased to several times its original value through the introduction of bunch lengthening harmonic cavities. One previously suggested expla

Numerical and experimental studies on scale models of lightweight building structures

Lightweight buildings are sensitive to low-frequency vibrations, making it difficult to construct them in such a way that noise and disturbing vibrations are kept at an acceptable level. In the design of vibration reduction measures, it is desirable to have computational models for predicting the effects of structural modifications. Validations of the models to experimental data have to be perform

Efficient evaluation of humoral immune responses by the use of serum pools

Background: Collection and testing of individual serum samples are often used in research to gain knowledge about e.g. the humoral response against bacteria or virus. This is a valid but time-consuming method and might be a waste of valuable serum samples for inefficient research. So far, no study has considered using serum pools as a quick and efficient screening method to confirm or deny hypothe

Parental estimation of their child's increased type 1 diabetes risk during the first 2 years of participation in an international observational study : Results from the TEDDY study

This study assessed mothers' and fathers' perception of their child's risk of getting type I diabetes (TID) during the first 2 years of their participation in The Environmental Determinants of Diabetes in the Young (TEDDY) study. TEDDY parents were informed of their child's increased genetic risk for Tl D at study inception. Parent perception of the child's risk was assessed at 3, 6, 15, and 27 mo

In-beam background suppression shield

The long (3 ms) proton pulse of the European Spallation Source (ESS) gives rise to unique and potentially high backgrounds for the instrument suite. In such a source an instrument's capabilities will be limited by its Signal to Noise (S/N) ratio. The instruments with a direct view of the moderator, which do not use a bender to help mitigate the fast neutron background, are the most challenging. Fo

The impact of gonadotropin receptor polymorphisms on human reproductive function

To date, approximately 15% of all couples worldwide suffer from infertility. The management include controlledovarian hyper-stimulation of the women with follicle-stimulating hormone (FSH) and semen analysis of the men,prior to in vitro fertilization (IVF) and transfer of the fertilized embryo to the uterine cavity. Approximately 250 000IVF cycles are performed worldwide each year, and as a result

Development and production of Non Evaporable Getter coatings for the vacuum chambers of the 3 GeV storage ring of MAX IV

MAX IV is presently under construction at Lund, Sweden, and the first beam for the production of synchrotron radiation is expected to circulate in 2016. The whole set of 3 GeV ring beam pipes is coated with Ti-Zr-V Non Evaporable Getter (NEG) thin film in order to fulfil the average pressure requirement of 1×10-9 mbar, despite the compact magnet layout and the large aspect ratio of the vacuum cham

Forecasting global atmospheric CO2

A new global atmospheric carbon dioxide (CO2) real-time forecast is now available as part of the pre- operational Monitoring of Atmospheric Composition and Climate – Interim Implementation (MACC-II) service us- ing the infrastructure of the European Centre for Medium- Range Weather Forecasts (ECMWF) Integrated Forecast- ing System (IFS). One of the strengths of the CO2 fore- casting system is that

Electroencephalographic characteristics of status epilepticus after cardiac arrest

Objective: To describe the electrophysiological characteristics and pathophysiological significance of electrographic status epilepticus (ESE) after cardiac arrest and specifically compare patients with unequivocal ESE to patients with rhythmic or periodic borderline patterns defined as possible ESE. Methods: Retrospective cohort study of consecutive patients treated with targeted temperature mana

Muco-epidermoid tumour of the bronchus

A 7-year-old boy with recurrent pneumonia of the right lower lobe is described. At bronchoscopy a small tumour almost totally obliterating the right lower lobe was detected. Surgical treatment was undertaken. Histopathologic studies showed findings consistent with those of a muco-epidermoid tumour. The case emphasizes bronchoscopy as an important investigation in children with recurrent pneumonia.

Endometrial cancer risk prediction including serum-based biomarkers : results from the EPIC cohort

Endometrial cancer risk prediction models including lifestyle, anthropometric and reproductive factors have limited discrimination. Adding biomarker data to these models may improve predictive capacity; to our knowledge, this has not been investigated for endometrial cancer. Using a nested case–control study within the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, we

Intra-tumour IgA1 is common in cancer and is correlated with poor prognosis in bladder cancer.

A high frequency of IgA1-positive tumour cells was found in tissue micro-arrays of oesophagus, colon, testis, lung, breast, bladder and ovarian cancer. IgA1 was observed in the cytoplasm and the plasma membrane. A correlation was found between intra-tumour IgA1 and poor overall survival in a large cohort of bladder cancer patients (n = 99, p = 0.011, log-rank test). The number of IgA1-positive tum
