The effluent water turbidity from the microsieve was maintained at various set points in the range 12-80 NTU basically independent for a number of studied vari

Measurement of deuteron spectra and elliptic flow in Pb–Pb collisions at √sNN = 2.76 TeV at the LHC

The transverse momentum (pT) spectra and elliptic flow coefficient (v2) of deuterons and anti-deuterons at mid-rapidity (| y| < 0.5) are measured with the ALICE detector at the LHC in Pb–Pb collisions at sNN = 2.76 TeV. The measurement of the pTspectra of (anti-)deuterons is done up to 8 GeV/ c in 0–10% centrality class and up to 6 GeV/ c in 10–20% and 20–40% centrality classes. The v2is measured

A 2.8-3.8-GHz Low-Spur DTC-Based DPLL With a Class-D DCO in 65-nm CMOS

We present a digital phase-locked loop (DPLL) operating from 2.8 to 3.8 GHz with an on-chip 40-MHz reference crystal oscillator. The DPLL makes use of a class-D digitally controlled oscillator and a digital-to-time converter with a single-bit (bang-bang) phase detector. The DPLL displays an excellent behavior in terms of in-band fractional spurs, which are consistently below -65 dBc across the tun

Integration of the ecosystem services concept in planning documents from six municipalities in southwestern Sweden

The ecosystem services (ES) concept refers to benefits that humanity receives from nature. Investigating how this concept has been embraced within urban planning is important when assessing the awareness of human dependence on natural functions and the potential for the ES concept to increase this awareness. We analyzed planning documents from three small and three large municipalities in southern

Humid air motor (HAM) is an engine operated with humidified inlet charge. System simulations study on HAM showed the waste heat recovery potential over a conventional system. An HAM setup was constructed, to comprehend the potential benefits in real-time, the HAM setup was built around a 13-litre six cylinder Volvo diesel engine. The HAM engine process is explained in detail in this paper. Emissio

Did Monetary Policy Matter? Narrative Evidence from the Classical Gold Standard

This paper investigates the causal effects of monetary policy on the British economy during the classical gold standard. Based on the narrative identification approach, I find that following a one percentage point monetary tightening, unemployment rose by 0.9 percentage points, while inflation fell by 3.1 percentage points. In addition, monetary policy shocks accounted for a third of macroeconomic

Numerical Estimation of Asymmetry of In-Cylinder Flow in a Light Duty Direct Injection Engine with Re-Entrant Piston Bowl

Partially premixed combustion (PPC) can be applied to decrease emissions and increase fuel efficiency in direct injection, compression ignition (DICI) combustion engines. PPC is strongly influenced by the mixing of fuel and oxidizer, which for a given fuel is controlled mainly by (a) the fuel injection, (b) the in-cylinder flow, and (c) the geometry and dynamics of the engine. As the injection tim

Revisiting Social Capital in Development: Can Group-Based Microfinance Reproduce Social Capital? : A case study in Rural Cambodia.

Group-based microfinance programmes, based on trust and solidarity among members, currently dominate development policy and practice as the approach compensates for individual poor’s lack of material resources and market imperfections. Despite strong evidence of its social and economic impact, few researches take an in-depth, empirical look at how the group models manifest and create social capita

Perspectives for surrogate safety studies in east-European countries

The road safety development in East-European countries follows in general the trends of the western countries, even though there is a time lag. The fatality numbers are decreasing, though the improvements for the vulnerable road users are less impressive compared to other road user categories. The traditional road safety analysis based on accident history has many limitations related to accident u

Neuroprotection and neurorestoration as experimental therapeutics for Parkinson's disease

Disease-modifying treatments remain an unmet medical need in Parkinson's disease (PD). Such treatments can be operationally defined as interventions that slow down the clinical evolution to advanced disease milestones. A treatment may achieve this outcome by either inhibiting primary neurodegenerative events ("neuroprotection") or boosting compensatory and regenerative mechanisms in the brain ("ne
