Analysis of Dual-Fuel CNG-Diesel Combustion Modes Towards High Efficiency and Low Emissions at Part Load
Previous research carried out by the authors described the role of dual-fuel combustion efficiency on overall engine efficiency at high diesel substitution ratio. At low loads, high diesel substitution ratios result in excessive total unburned hydrocarbon emissions due to bulk flame quenching, and consequently lower substitution ratios in combination with intake air heating, throttling and increas

Comparison of Negative Valve Overlap (NVO) and Rebreathing Valve Strategies on a Gasoline PPC Engine at Low Load and Idle Operating Conditions
Gasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions. Running the engine in PPC mode with high octane number fuels has the advantage of a longer premix period of fuel and air which reduces soot emissions. The problem is the ignitability at low load and idle operating conditions.In a previous study it was shown that it is possGasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions.

PON-SC - program for identifying steric clashes caused by amino acid substitutions
Background: Amino acid substitutions due to DNA nucleotide replacements are frequently disease-causing because of affecting functionally important sites. If the substituting amino acid does not fit into the protein, it causes structural alterations that are often harmful. Clashes of amino acids cause local or global structural changes. Testing structural compatibility of variations has been diffic
Peirce Knew Why Abduction Isn’t IBE—A Scheme and Critical Questions for Abductive Argument
Whether abduction is treated as an argument or as an inference, the mainstream view presupposes a tight connection between abduction and inference to the best explanation (IBE). This paper critically evaluates this link and supports a narrower view on abduction. Our main thesis is that merely the hypothesis-generative aspect, but not the evaluative aspect, is properly abductive in the sense introd
Physical therapists as first-line diagnosticians for traumatic acute rotator cuff tears : a prospective study
Background: Early diagnosis of traumatic acute full-thickness rotator cuff tears (FTRCT) is important to offer early surgical repair. Late repairs following fatty infiltration of the rotator cuff muscles have less favorable results. We think that physical therapists are valuable diagnosticians in a screening process. The objective of this study was to evaluate the usefulness of physical therapists
Automated telephone interventions for problematic alcohol use in clinical and population samples : A randomized controlled trial NCT01958359 NCT
Objective: The primary objective was to evaluate 6-month outcomes for brief and extensive automated telephony interventions targeting problematic alcohol use, in comparison to an assessment-only control group. The secondary objective was to compare levels of problematic alcohol use (hazardous, harmful or probable dependence), gender and age among study participants from clinical psychiatric and ad
A study on compression braking as a means for brake energy recovery for pneumatic hybrid powertrains
Hybrid powertrains have become a very attractive technology over the last ten years due to their potential for lowering fuel consumption and emissions. A large portion of all manufacturers worldwide are now focusing on hybrid electric powertrains, which are the most common hybrid powertrains of today. However, in recent years a new technology has emerged, namely the pneumatic hybrid powertrain. Al
Body mass index influences the prognostic impact of combined nuclear insulin receptor and estrogen receptor expression in primary breast cancer
The prognostic importance of tumor-specific nuclear insulin receptor (InsR) expression in breast cancer is unclear, while membrane and cytoplasmic localization of InsR is better characterized. The insulin signaling network is influenced by obesity and may interact with the estrogen receptor a (ERα) signaling. The purpose was to investigate the interplay between nuclear InsR, ER, body mass index (B
Joining, belonging, and re-valuing : a process of meaning-making through group participation in a mental health lifestyle intervention
Background: Balancing Everyday Life (BEL), a new group-based intervention for mental health service users, was implemented in Sweden. Mental health service users often experience group interventions as meaningful, but knowledge of the process of meaning-making in a group is lacking. Aim: To explore participants’ perceptions of the group in the Balancing Everyday Life (BEL) lifestyle intervention;
Prerequisites and driving forces behind an extended working life among older workers
Background: Reforms are changing pension systems in many European countries, in order to both restrict early retirement and force people to extend their working life. From occupational therapy and occupational science perspectives, studies focusing on aspects of working life that motivate the older worker is urgent. Aim: The aim was to describe incentives behind an extended working life among peop
Resolving the Structure of a Well-Ordered Hydroxyl Overlayer on In2O3(111) : Nanomanipulation and Theory
Changes in chemical and physical properties resulting from water adsorption play an important role in the characterization and performance of device-relevant materials. Studies of model oxides with well-characterized surfaces can provide detailed information that is vital for a general understanding of water-oxide interactions. In this work, we study single crystals of indium oxide, the prototypic
Infrared spectroscopy as molecular probe of the macroscopic metal-liquid interface
Metal-liquid interfaces are of the utmost importance in a number of scientific areas, including electrochemistry and catalysis. However, complicated analytical methods and sample preparation are usually required to study the interfacial phenomena. We propose an infrared spectroscopic approach that enables investigating the molecular interactions at the interface, but needing only minimal or no sam
Can System Truncation Speed up Ligand-Binding Calculations with Periodic Free-Energy Simulations?
We have investigated whether alchemical free-energy perturbation calculations of relative binding energies can be sped up by simulating a truncated protein. Previous studies with spherical nonperiodic systems showed that the number of simulated atoms could be reduced by a factor of 26 without affecting the calculated binding free energies by more than 0.5 kJ/mol on average (Genheden, S.; Ryde, U.
