Context: During systematic literature reviews it is necessary to assess the quality of empirical papers. Current guidelines suggest that two researchers should independently apply a quality checklist and any disagreements must be resolved. However, there is little empirical evidence concerning the effectiveness of these guidelines. Aims: This paper investigates the three techniques that can be use

In this paper we discuss $(\epsilon,\delta)$-Freudenthal Kantor triple systems with certain structure on the subspace $L_{-2}$ of the corresponding standard embedding five graded Lie (super)algebra $L(\epsilon,\delta):=L_{-2}\oplus L_{-1}\oplus L_0\oplus L_1\oplus L_2; [L_i,L_j]\subseteq L_{i+j}$. We recall Lie and Jordan structures associated with $(\epsilon,\delta)$-Freudenthal Kantor triple sys

In this paper, we propose a statistical theoretical framework for incorporation of sensor and actuator faults in dynamic simulations of wastewater treatment operation. Sensor and actuator faults and failures are often neglected in simulations for control strategy development and testing, although it is well known that they represent a significant obstacle for realising control at full-scale facili

Statistical modeling of atrioventricular (AV) nodal function during atrial fibrillation (AF) is revisited for the purpose of defining model properties and improving parameter estimation. The characterization of AV nodal pathways is made more detailed and the number of pathways is now determined by the Bayesian information criterion, rather than just producing a probability as was previously done.

Purpose – The two-fold purpose of this paper is identifying areas of difficulty in managing the needs of end-users in the course of the design and delivery of construction projects and suggesting possible solutions. Design/methodology/approach – The focus of the paper is the interaction between three principal parties: end-users, project leader (a selected end-user) and facility planner (a facil

Chronic granulomatous disease (CGD) is an inherited disorder characterized by recurrent life-threatening bacterial and fungal infections. CGD results from defective production of reactive oxygen species by phagocytes caused by mutations in genes encoding the NADPH oxidase 2 (NOX2) complex subunits. Mice with a spontaneous mutation in Ncf1, which encodes the NCF1 (p47(Phox)) subunit of NOX2, have d

Popular Abstract in Swedish I det här arbetet studerades kontaktallergi för metaller som finns i olika stentar. Patienterna som ingick i studien hade blivit stentade med olika typer av stentar. En av stentarna var gjord av rostfritt stål (nickelstent) och den andra var förgylld (guldstent). Resultaten av lapptestningen visade att patienterna hade en hög frekvens av både guld- och nickelallergi, ocA large number of patients are treated with coronary stents, and restenosis (recurrent narrowing of the vessel) is a serious problem. Contact allergy to metal ions eluted from stainless steel stents has been suggested to contribute to in-stent restenosis. Studies have reported a higher rate of restenosis with gold-plated stents, but the correlation to contact allergy was not evaluated. Nickel is t

The tumor suppressor CYLD and the proto-oncogene BCL-3 are known to be deregulated in various cancer types. The molecular background of how these genes participate in carcinogenesis is not fully understood. CYLD is a deubiquitinating enzyme known to specifically target lysine 63 linked ubiquitin chains, which can negatively regulate the BCL-3, NF-κB and JNK signaling pathways, leading to a decreas

In 2011 the C9ORF72 repeat expansion was identified as the most frequent genetic mutation underlying FTD and ALS. The main aim of this study was to investigate clinical characteristics in a large C9ORF72-positive FTD family, and to compare these with the neuropathological findings.

In electromyographic (EMG) and functional magnetic resonance imaging (fMRI) studies, muscle and brain activity was compared during low levels of tooth clenching using a novel biting device to control bite force. A total of 21 healthy subjects performed motor tasks, comprising tooth clenching at 5, 10 and 20N. During all measurements, subjects kept the novel bite device between the anterior teeth d

The absorption, tissue distribution and excretion of enteral alpha-ketoglutarate (AKG) was studied in four experiments. Six male Sprague Dawley rats were used to investigate the excretion of AKG in urine and faeces. Thirty rats, randomly assigned to five groups, were used to investigate the distribution of AKG in body tissues. They were gavaged with AKG enriched with 3 muCi/kg BW of (14)C uniforml

Objective: The home birth rate in Sweden is less than 1 in 1000, and home birth is not included within the health care system. This study describes women's experiences concerning reactions to their decision to give birth at home. Design and setting: A nationwide survey (SHE - Swedish Homebirth Experience) in Sweden was conducted between 1992 and 2005 whereas 735 women had given birth to 1038 child

Purpose: The purpose of this paper is to sketch out the general tendencies, gaps, and opportunities within the body of research studying the social web as a new facet of public librarianship in order to delineate the findings so far and suggest directions for future research. Study design: Literature searches were conducted through the LISTA database, The ISI Web of Science database and The Direct

We show that the geometry of the Wilson lines, entering the operator definition of the transverse-momentum dependent parton distributions and that of the soft factor, follows from the kinematics of the underlying physical process in conjunction with the gauge invariance of the QCD Lagrangian. We demonstrate our method in terms of concrete examples and determine the paths of the associated Wilson l

Questions: How does the number of species in a community affect the level of genetic diversity of its constituent species? What is the relation between competitive interactions and the spatial distribution of genetic variation? When spatially structured, how is the genetic differentiation among subpopulations affected by competition and size of the community? Model features and key assumptions: A
