The Republic of Moldova is celebrating 20 years of independence and is still almost completely dependent on energy imports from the Russian federation. Renewable energy is in its infancy despite a climate that is well suited for solar and wind energy with 2,300 sunshine hours per year and measured wind speeds up to 8.5 m/s. Moldova has a history of wine production and wide spread usage of more tha
A new optical interferometer for delay stabilization in attosecond pump/probe experiments is constructed, featuring a custom-made hole-drilled recombination mirror and using a co-propagating HeNe laser for the interference. The interferometer is shown to generate an interference pattern of high enough contrast for delay stabilization. The stability of the measured delay is tested with the interfer
This paper examines the standing of private firms in the post-privatization economic reform in China regarding their access to human capital. The cross-sectional dataset used to test the model is extracted from the World Bank 2012 Enterprise Survey. Using a sample of 2848 Chinese firms of diverse ownership types, the paper studies the effect of firm ownership on human capital, and further studies
Happiness is a relatively new discipline within economics. Traditionally, economists have not paid too much attention to it since they considered that both indicators and theoretical assumptions in which this discipline was based were not neither reliable nor useful for policy recommendations. However, especially in the last decade, there has been extensive research which, if not proved, at least
CO2 Catalysis has been studied with Planar Laser Induced Fluorescence (PLIF) in combination with a mass spectrometer for a small, 23 cubic centimeters, cube shaped flow reactor. Both catalysis processes with one and with two catalysts inside the reactor have been carried out and analysed. Some results have been visualised by images showing concentration, given by the PLIF signal, of CO2 inside the
Internal erosion is one of the major reasons for embankment dam failures. Despite this, the knowledge of the temporal development of internal erosion in full scale structures is limited. Detection of internal erosion is complicated using conventional methods, and new or improved methods are appreciated. Hallby was the first Swedish embankment to get a permanently installed monitoring system intend
The first search for nonresonant Bc+→π+μ+μ- decays is reported. The analysis uses proton–proton collision data collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9fb-1. No evidence for an excess of signal events over background is observed and an upper limit is set on the branching fraction ratio B(Bc+→π+μ+μ-)/B(Bc+→J/ψπ+)
We are now seeing the development of a new generation of synchrotron radiation sources, the seeded, short-wavelength Free Electron Lasers (FELs), which are capable of driving the radiation to even higher intensities, and with new capabilities such as longitudinal coherence and ultra-short pulses. The Workshop on High-harmonic Seeding for Present and Future Short Wavelength Free-Electron Lasers, ho
Background: The aim was to investigate the noise and bias properties of quantitative 177Lu-SPECT with respect to the number of projection angles, and the number of subsets and iterations in the OS-EM reconstruction, for different total acquisition times. Methods: Experimental SPECT acquisition of six spheres in a NEMA body phantom filled with 177Lu was performed, using medium-energy collimators an
In this paper we propose a scheme for test planning and test access mechanism (TAM) design for stacked integrated circuits (SICs) that are designed in a core-based manner. Our scheme minimizes the test cost, which is given as the weighted sum of the test time and the TAM width. The test cost is evaluated for a test flow that consists of a wafer sort test of each individual chip and a package test
In this introductory article, we explain the purpose of this special issue that is set up as a Festschrift in honour of the (editorial) work of BengtJohannisson. Inspired by Italo Calvino's Six Memos for the Next Millennium, the special issue is structured along six essays that are both commemorative and affirmative, that is we use the work of Johannisson to explore fresh waters and invent new pra
Many concepts for future generations of wireless communication systems use coherent processing of signals from many distributed antennas. The aim is to improve communication reliability, capacity, and energy efficiency and provide possibilities for new applications through integrated communication and sensing. The large bandwidths available in the higher bands have inspired much work regarding sen
This paper presents a simple and effective control solution to regulate temperature and humidity inside a greenhouse, which are the main climatic variables affecting crop growth and health. A multivariable control strategy with inverted decoupling is proposed in two schemes. The nighttime control scheme uses heating and dehumidification, and the daytime control scheme uses natural ventilation, deh
The current landscape of biopharmaceutical production necessitates an ever-growing set of tools to meet the demands for shorter development times and lower production costs. One path towards meeting these demands is the implementation of digital tools in the development stages. Mathematical modelling of process chromatography, one of the key unit operations in the biopharmaceutical downstream proc
Human neutrophils are activated by the beta-galactoside-binding lectin galectin-3, provided that the cells are primed by in vivo extravasation or by in vitro preactivation with, for example, LPS. Removal of terminal sialic acid can change neutrophil functionality and responsiveness due to exposure of underlying glycoconjugate receptors or change in surface charge. Here, we investigated whether suc
Mikhlin's method for solving Laplace's equation in domains exterior to a number of closed contours is discussed with particular emphasis on the Dirichlet-Neutnann map. In the literature there already exit tyro computational modes for Mikhlin's method. Here a new mode is presented. The new mode is at least as stable as the previous modes. Furthermore, its computational complexity in the number of c
Background: Free and total human kallikrein 2 (hK2) might improve the discrimination between prostate cancer and benign prostatic hyperplasia. Concentrations of hK2 are 100-fold lower than concentrations of prostate-specific antigen (PSA); therefore, an hK2 assay must have a low detection limit and good specificity. Methods: PSA- and hK2-specific monoclonal antibodies were used in solid-phase, two
