In the present paper, the heat transfer of gravity-driven dense particle flow around five different shapes of tubes is numerically studied using discrete element method (DEM). The velocity vector, particle contact number, particle contact time and heat transfer coefficient of particle flow at different particle zones around the tube are carefully analyzed. The results show that the effect of tube

Although elevated blood or sputum eosinophils are present in many patients with chronic obstructive pulmonary disease (COPD), uncertainties remain regarding the anatomical distribution pattern of lung-infiltrating eosinophils. Basophils have remained virtually unexplored in COPD. This study mapped tissue-infiltrating eosinophils, basophils, and eosinophil-promoting immune mechanisms in COPD-affect

The determination of reversible phase transitions in the perovskite-type thermoelectric oxide Eu0.8Ca0.2TiO3–δ is fundamental, since structural changes largely affect the thermal and electrical transport properties. The phase transitions were characterized by heat capacity measurements, Rietveld refinements, and pair distribution function (PDF) analysis of the diffraction data to achieve informati

The United Arab Emirates National Diabetes and Lifestyle Study (UAEDIAB) has identified obesity, hypertension, obstructive sleep apnea, and dyslipidemia as common phenotypic characteristics correlated with diabetes mellitus status. As these phenotypes are usually linked with genetic variants, we hypothesized that these phenotypes share single nucleotide polymorphism (SNP)-clusters that can be used

The human epidermal growth factor receptor 2 (HER2) is a clinically validated target for cancer therapy, and targeted therapies are often used in regimens for patients with a high HER2 expression level. Despite the success of current drugs, a number of patients succumb to their disease, which motivates development of novel drugs with other modes of action. We have previously shown that an albumin

Field studies were conducted during three years to determine the vertical (height level) and horizontal (distance from stand edge) distribution of flying Neodiprion sertifer (Geoffroy) males in a non-outbreak population. Sticky traps baited with synthetic female pheromone (25, 35, 75-diprionyl acetate) were used in a mature stand of Scots pine (Pinus sylvestris L.) in Central Europe (southern Bohe

The morphology and physiology of pheromone receptors on the antennae of male pine sawflies, Diprion pini L., were investigated. Using scanning electron microscopy, five sensillar types were recognized. The type shown to be pheromone sensitive has a long (50-70 μm) cuticular hair, is single-walled, and is innervated by 8 or 9 sensory cells as revealed by transmission electron microscopy. Electroant

Mating disruption of the pine sawfly Neodiprion sertifer (Geoffroy) (Hymenoptera: Diprionidae) was strongly indicated by reduced male trap catches in pine plantations permeated with the sex pheromone, (2S, 3S, 7S)‐diprionyl acetate. The trap catch reduction was 95 to near 100% when dispensers every 10 m were used, giving a total release of about 3 mg per hectare and day. Two mg of pheromone per co

The spatial distribution of catches of male European pine sawfly, Neodiprion sertifer (Geoffr.) (Hymenoptera, Diprionidae), was studied using different pheromone trap arrays. In hexagonal trap groups, trap interference was evident by reduced catch in the central of seven traps spaced 10 to 40 m apart. When the trap spacings were either 5 or 80 m no significant reduction could be shown. The interac

The main component of the sex pheromone secretion of female Diprion pini L. (Hymenoptera: Diprionidae) from insects collected both in Finland and in France has been identified as a threo-3,7-dimethyl-2-tridecanol (8 ng per female) stereoisomer by GC-MS and synthesis. The secretion also contains lower and higher homologues in small amounts (1-4% of the main component). Combined gas chromatographic-

Variation in number of European pine sawflies Neodiprion sertifer caught in pheromone traps during 11 d of the peak flight period was in part explained by weather. Daily average air temperature was the most important variable and explained 86% of the variation. A threshold for flight was c+11°C. Rain during most of the day inhibited flight, but occasional showers did not. -from Authors

We have previously demonstrated that a strong correlation exists between systemic vasculitis with proteinase 3-anti-neutrophil cytoplasm antibodies (PR3-ANCA) and heterozygosity for α1-antitrypsin (α1-AT) deficiency, PiZ. In the present study we characterized the PiZ-positive subgroup by laboratory findings, clinical features and outcome. The series studied consisted of 18 PiZ-positive and 81 PiZ-

We describe the clinical presentation and outcome in a series of eight patients with systemic necrotizing vasculitis and severe alpha1-antitrypsin (AAT) deficiency followed up at three Swedish hospitals during 1968-92. We also review six other cases reported in the literature during the same period. Diagnosis of severe AAT deficiency was based on the presence of the PiZZ phenotype, or low plasma t

Detection of antineutrophil cytoplasmic antibodies (ANCA) has become a useful tool in the diagnosis of Wegener's granulomatosis and microscopic polyangiitis. However, the results obtained with indirect immunofluorescence (IIF) and by ELISA for ANCA demonstration do not always correlate. A possible explanation for this finding could be that proteins are denatured during the process of antigen purif

Background. Recurrent antineutrophil cytoplasmic antibody (ANCA)- associated small vessel vasculitis (ANCA-SVV) after renal transplantation has been described in case series. However, general information regarding the frequency, character, and predictors of recurrent disease after transplantation is currently lacking. We considered the rate of relapse, whether a positive ANCA at the time of transp

In ANCA-associated small vessel vasculitis few genetic factors have proven to be of importance for disease susceptibility, an exception being deficiency of α1-anti-trypsin, the main inhibitor of proteinase 3 (PR3). Alerted by our finding that myeloperoxidase has affinity for C3, and the finding of an increased frequency of the C3F allele in systemic vasculitis in a British cohort, we examined poly
