The effect of combustion on a gliding arc (GA) discharge is investigated using simultaneous measurements of current and voltage waveforms, as well as imaging and spectroscopic analysis of plasma and flame luminescence. Attributed to the existence of flame, the breakdown voltage and current peak are reduced and the bright sparks during breakdown are dampened. The intrinsic reason is largely owing t

Purpose: The purpose of this study is to investigate the effects of human capital and relational trust on business-to-business (B2B) brand equity. Design/methodology/approach: Data collection was conducted among the clients of one of the Big Four auditing firms in Sweden. Structural equation modeling was used to test the hypothesized effects. Findings: The results demonstrate positive effects of h

In the present study, water-oil flow patterns and slug hydrodynamics were experimentally studied in square glass microchannels with various hydraulic diameters (Dh = 600 µm, 400 µm, 200 µm). The aqueous phase is the continuous phase while the organic phase is the dispersed phase. The ranges of flow rates of the continuous phase and the dispersed phase are 0-200 ml/h and 0-12 ml/h, 0-120 ml/h and 0

An in-cycle closed-loop combustion controller is proposed in this paper. The controller uses a pilot-main injection scheme where the cycle-individual properties of the pilot combustion are estimated by in-cylinder pressure measurements, and used to predict their effect on the heat release shape of the main combustion. The prediction is used to obtain the optimal main SOI that gives the Maximum Rea

After Tony Blair resigned as the United Kingdom’s prime minster in June 2007, he was appointed as the official envoy of the Quartet on the Middle East. His appointment was marred with controversy not the least with regard to his suitability for the role and his performance as peace envoy, with many observers questioning his ethical credentials. The EU along with the US, Russia and the UN make up t

Localization microscopy methods like Stochastic Optical Reconstruction Microscopy (STORM) are very well suited for exploring clustering of proteins, as the data inherently provide a list of molecular coordinates. Here we use state-of-art cluster analysis algorithms (DBSCAN) to explore the clustering behaviour of different affinity forms of the integrin LFA-1. It has been suggested that LFA-1 may f

Activation of the contact system generates bradykinin from high-molecular-weight kininogen and has been suggested to participate in the pathophysiology of sepsis. To test this, we prospectively measured bradykinin and high-molecular-weight kininogen levels in a cohort of sepsis patients requiring intensive care. From 29 patients meeting criteria for sepsis or septic shock according to Sepsis-3, bl

Stopovers play a crucial role for the success of migrating animals and are key to optimal migration theory. Variation in refuelling rates, stopover duration and departure decisions among individuals has been related to several external factors. The physiological mechanisms shaping stopover ecology are, however, less well understood. Here, we explore how immune function and blood parasite infection

Background: One goal within positive psychiatry is to support the personal recovery of persons with mental illness and providing opportunities for well-being. Aim: The current article aims to introduce readers to the concept of personal recovery and the potential and importance of recovery-oriented services and measures. Methods: A literature review was conducted to help consider the domains of ‘p

Background/Purpose: The aims of this study were to evaluate bowel and urinary tract function, to identify predictors for dysfunctional outcome and to evaluate health-related quality-of life (QoL) in patients treated for sacrococcygeal teratomas (SCT). Methods: Medical records of patients with SCT born between 1985 and 2015 treated at three Swedish pediatric surgical centers were reviewed. Question

Objectives: Inclusion body myositis is characterized by inflammatory and degenerative changes, but the temporal relation of these events is unknown. Materials and Methods: In nineteen patients with inclusion body myositis, muscle strength was correlated with inflammatory and degenerative findings on magnetic resonance imaging (MRI) and in muscle biopsies in three different muscles (tibialis anteri

Gasoline-fueled Partially Premixed Combustion is an advanced combustion concept approaching high efficiency as well as low emissions. The most challenging task on controlling a gasoline PPC engine is to regulate the maximum pressure rise rate to reduce engine noise and durability problem. A trade-off relationship between pressure rise rate and soot emissions is observed as a function of pilot inje

The quinoline-3-carboxamides (Q compounds) are a family of small molecules with immunomodulatory functions that have shown efficacy in various murine models of inflammatory diseases. One such compound has demonstrated antitumor effects in murine models. Q compounds bind to S100A9, thereby preventing its ligation to TLR4 and RAGE. S100A9 is a small molecule which has shown to have a role in the est

Growing evidence suggests that people with autoimmune conditions may be at increased risk of hepatobiliary tumors. In the present study, we evaluated associations between autoimmune conditions and hepatobiliary cancers among adults aged ≥66 in the United States. We used Surveillance, Epidemiology, and End Results (SEER)-Medicare data (1992–2013) to conduct a population-based, case–control study. C

This paper presents a review of particle deposition research in film-cooled gas turbines based on the recent open literature. Factors affecting deposition capture efficiency and film cooling effectiveness are analyzed. Experimental studies are summarized into two discussions in actual and virtual deposition environments. For investigation in virtual deposition environments, available and reasonabl

Objective: To characterize sociodemographic differences in semen parameters among US men undergoing a semen analysis. Materials and Methods: Men who provided a semen sample were identified from insurance claims between 2007 and 2016. Differences in semen parameters were characterized according to age, race, education, and region. Mean semen parameters and proportions of men with suboptimal paramet

The non-uniform conditions and potential progression of fires in larger spaces calls for modelling methods extending outside of the traditional compartment fire framework. Even though a handful of studies in the area exist there is still little guidance available on how progressing fires in large enclosures can be modelled. Three different methods to calculate far-field gas temperature in large en
