NOx-Conversion Comparison of a SCR-Catalyst Using a Novel Biomimetic Effervescent Injector on a Heavy-Duty Engine

NOx pollution from diesel engines has been stated as causing over 10 000 pre-mature deaths annually and predictions are showing that this level will increase [1]. In order to decrease this growing global problem, exhaust after-treatment systems for diesel engines have to be improved, this is especially so for vehicles carrying freight as their use of diesel engines is expected to carry on into the

Wood ash application in a managed Norway spruce plantation did not affect ectomycorrhizal diversity or N retention capacity

Ectomycorrhizal (ECM) fungi are key players in N cycling in coniferous forests, and forest management such as application of wood ash can affect their functionality. The aim of this study was to determine the effects of wood ash application on ECM fungal mycelial production, capacity to retain N, diversity and community composition. In-growth mesh bags were installed in control and treated plots.

Orbifold projection in supersymmetric QCD at N(f) ≤ N(c)

Supersymmetric orbifold projection of N = 1 SQCD with relatively small number of flavors (N(f) ≤ N(c)) is considered. The purpose is to check whether orbifolding commutes with the infrared limit. On the one hand, one considers the orbifold projection of SQCD and obtains the low-energy description of the resulting theory. On the other hand, one starts with the low-energy effective theory of the ori

Haemophilus influenzae – typing, epidemiology and beta-lactam resistance

Haemophilus influenzae är en bakterie som lever i människans luftvägar. Ofta orsakar bakterien ingen skada hos personen som bär den, men ibland orsakar H. influenzae luftvägsinfektioner såsom öroninflammation hos barn, akut försämring hos patienter med kroniskt obstruktiv luftvägssjukdom (KOL) samt lunginflammation. Bakterien kan också orsaka allvarliga infektioner såsom blodförgiftning och hjärnhHaemophilus influenzae is a common cause of respiratory tract infections such as acute otitis media (AOM), exacerbations of chronic obstructive pulmonary disease (COPD) and pneumonia. The species is subdivided into encapsulated and non-encapsulated strains, designated type a-f and nontypeable H. influenzae (NTHi), respectively. Prior to introduction of polysaccharide-protein conjugate vaccines aga

Proposal for a classification of ISO22400 KPIs for manufacturing operations management

The ISO22400 standard defines key performance indicators for manufacturing operation management. Its visionary goal is to be applicable to all industry types, regardless the production methodology and the process configuration. Pursuing this objective, a challenging trade-off between generality and specificity in the definitions must be found. In the cited standard, the former approach has been pr

Polyporales brown rot species Fomitopsis pinicola : Enzyme activity profiles, oxalic acid production, and Fe3+-reducing metabolite secretion

Basidiomycota fungi in the order Polyporales are specified to decomposition of dead wood and woody debris and thereby are crucial players in the degradation of organic matter and cycling of carbon in the forest ecosystems. Polyporales wood-decaying species comprise both white rot and brown rot fungi, based on their mode of wood decay. While the white rot fungi are able to attack and decompose all

Quantitative in-cylinder fuel measurements in a heavy duty diesel engine using structured laser illumination planar imaging (SLIPI)

Laser-induced fluorescence (LIF) for quantitative fuel concentration measurements in a combustion engine is a challenging task. Measuring close to the walls of the combustion chamber is even more challenging as both the incident laser light and the signal are strongly reflected on the walls of the combustion chamber. By using a new technique called Structured Laser Illumination Planar Imaging (SLI

Social Work on the Whiteboard : Governing by Comparing Performance

This article explores a number-based comparative logic unfolding around a particular kind of meeting in a social work setting: a daily and short gathering referred to as a “pulse meeting”. At such meetings, staff gather around a whiteboard visualizing individual statistics in terms of the number of client meetings performed or assistance decisions made.

Identification of linear, multivariable systems operating under linear feedback control

The possibility of estimating process parameters using input-output data collected when the system operates in closed loop is discussed in this paper. Concepts that are useful for a systematic treatment of the problem are introduced. The results refer to the case where the regulator is a linear feedback law or alternates between several such laws. It is shown that a straightforwardly applied ident

Five-year changes in dietary intake and body composition in adolescents with severe obesity undergoing laparoscopic Roux-en-Y gastric bypass surgery

Background: Information is scarce on long-term changes in energy intake (EI), dietary energy density (DED), and body composition in adolescents undergoing laparoscopic Roux-en-Y gastric bypass (RYGB). Objectives: To investigate long-term changes in EI, DED, and body composition in adolescents after LRYGB. Setting: University hospitals, multicenter study, Sweden. Methods: Eighty-five adolescents (6

Estimating CDKN2A mutation carrier probability among global familial melanoma cases using GenoMELPREDICT

BACKGROUND: Although rare in the general population, highly penetrant germline mutations in CDKN2A are responsible for 5-40% of melanoma cases reported in melanoma-prone families. We sought to determine whether MELPREDICT was generalizable to a global series of melanoma families and whether performance improvements can be achieved.METHODS: 2,116 familial melanoma cases were ascertained by the inte

Extruded Unripe Plantain Flour as an Indigestible Carbohydrate-Rich Ingredient

There is a growing interest in the development of functional ingredients, including those with high indigestible carbohydrate content. Unripe plantain flour (UPF) is a source of indigestible carbohydrates, type II resistant starch (RS) in particular. A major drawback of UPF, however, is that its RS content decreases sharply after wet heat treatment. Here, we explore the possibility of preparing an
