Distributed projects are generally recognized as being more complex and adding a number of new challenges to project management. Configuration management (CM) can be considered the infrastructure of all types of project being they co-located or distributed and lack of CM or badly implemented CM will hurt any type of project. In this paper, we take a closer look at the role of CM in distributed pro

Full-cycle simulations of a spark ignition engine running on a primary reference fuel have been performed using a two-zone model. A detailed kinetic mechanism is taken into account in each of the zones, while the propagating flame front is calculated from a Wiebe function. The initial conditions for the unburned gas zone were calculated as a mixture of fresh gas and rest gas. The composition of th

In this paper, we investigate the impact of power amplifier (PA) nonlinear distortion in pre-coded multi-user large antenna or massive MIMO downlink systems. First, detailed signal and system models are derived for the received signal at single-antenna user equipment (UE) under channel-aware linear precoding in the base-station combined with behavioral models for the individual PA units, covering

Objective: Changes observed during adult GH deficiency (GHD) are most often reversed with the administration of recombinant human GH (rhGH). To avoid daily injections, a long-acting GH molecule has been obtained by covalent binding of polyethylene glycol (PEG) with rhGH (PEG-GH), allowing weekly s.c. injections. This study was designed to assess its efficacy and safety, in adult GHD subjects.Desig

Sustainable digitalization in industry requires extensive preplanning to integrate business strategies with the concept of digitalized sustainability. However, stakeholders often have different perspectives, making alignment more challenging. Stakeholders in the digitalized sustainable manufacturing industry must be identified and prioritized for effective implementation. Therefore, the present st

We demonstrate transport spectroscopy on bottom-up grown few-electron quantum dots in semiconductor nanowires. The dots are defined by InP double barrier heterostructures in InAs nanowires catalytically grown from nanoparticles. By changing the dot size, we can design devices ranging from single-electron transistors to few-electron quantum dots. In the latter case, electrons can be added one by on

Ag/alumina catalysts with different silver loading (1.28 - 6 wt %) for lean NO reduction activity were prepared by impregnation and the incipient wetness method. Complementary HRTEM, HAADF, O-2-chemisorption, and EDXS studies were applied to investigate the dependence between silver particle size and catalytic activities of the prepared materials. The catalyst with the lowest silver loading (1.28

We study the statistical properties of the electric pygmy dipole resonance in four different isotones with neutron number N = 82. These nuclei are Ba-138(56), Ce-140(58), Nd-142(60), (144)(62)sm. The data set comprises levels with spin and parity J(pi) = 1(-) and their ground state B(E1) transition strengths. The statistics are found to be "mixed", i.e., in between the predictions of random matrix

Objective. Helicobacter DNA has been detected in the hepatobiliary tree of patients with chronic liver diseases (CLD). The presence of H. pylori in the stomach compared with in the liver of the same patients with CLD has not been studied, therefore to the aim of this study was to investigate the presence of Helicobacter DNA and antigens in the liver and stomach of Polish patients with chronic live

We report on the preliminary results from a study of the decay of the I-pi = 8(+) T-1/2 = 2 mu s isomer in Pd-96 performed as part of the Stopped-Beam RISING campaign within the Rare Isotope Investigation at GSI (RISING). The Pd-96 ions were produced following the projectile fragmentation of a 750 MeV per nucleon Ag-107 primary beam. The reaction products were separated and identified by the in-fl

Wobbling is a rotational mode unique to a triaxial body. The Lu-Hf isotopes with N similar to 94 at high spin provide a possible region of nuclei with pronounced triaxiality. We have investigated Lu-163 through the fusion-evaporation reaction La-139(Si-29,5n)Lu-163 with a beam energy of 152 MeV. Three excited bands decaying into the known, presumably triaxial, superdeformed (TSD) band built on the

Pathogenic microbes have evolved sophisticated molecular strategies to subvert host defenses. Here we show that virulent bacteria interfere directly with Toll-like receptor (TLR) function by secreting inhibitory homologs of the Toll/interleukin-1 receptor (TIR) domain. Genes encoding TIR domain containing–proteins (Tcps) were identified in Escherichia coli CFT073 (TcpC) and Brucella melitensis (Tc
