Ammonia is regarded as a potential carbon-free alternative fuel. To have a better understanding of its combustion characteristics, development of feasible techniques for ammonia detection in combustion environments is essential. In the present work, planar laser-induced photofragmentation fluorescence (LIPF) was developed for quantitative measurements of ammonia in hot gas flows. A 193 nm ArF exci
nterspecific hybridization had been long recognized as a widespread evolutionary process in vascular plants. In the present review, we summarize knowledge concerning studies of interspecific hybridization in bryophytes before and after the advent of molecular methods. The available data indicate that hybridization is an important evolutionary phenomenon among bryophytes. evidence fo
Some parasites are expected to have beneficial impacts on wild populations in polluted environments because of their bioaccumulation potential of pollutants from their hosts. The fate of organic micropollutants in host-parasite systems and the combined effect of parasitism and pollution were investigated in chub Squalius cephalus, a freshwater fish, infected (n = 73) or uninfected (n = 45) by acan
In this paper we argue that comprehensive and systematic parental education has the potential to equip young adults with the necessary information for the responsible exercise of their autonomy in choices about reproduction and parenting. Education can allow young adults to acquire largely accurate beliefs about reproduction and parenting and about the implications of their reproductive and parent
Connected Autonomous Vehicles (AVs) with Vehicle-to-Vehicle (V2V) communication are becoming an essential component of the transportation system. Self-driving cars have the potential to optimize the roads' traffic flow, fuel consumption and remove the possibility of human error and distractions. In these systems, all involved vehicles must be fully autonomous for maximum gain. However, a fully aut
The direct reaction between carbohydrates and CO2 has recently attracted attention in the context of cellulose dissolution and derivatization as well as carbon capture applications. We have directly demonstrated the formation of cellulose carbonate upon the introduction of CO2 into a non-aqueous cellulose solution by nuclear magnetic resonance spectroscopy. Comparison of the observed spectra with
Parkinson’s disease (PD) is one of the most common neurodegenerative disorders. The motor and non-motor symptoms of PD lead to a number of consequences in everyday life for persons with PD (PwPD). PwPD continuously need to adapt to their new life situation and despite medical treatment, the impact of PD on everyday life is inevitable and can lead to a lower level of life satisfaction (LS). LS is a
Vasectomy is a practical and straightforward approach to birth control. This paper presented a 31-year-old patient who desired torestore his fertility five years after being vasectomized. He met several obstacles. He developed severe psychological distress withsymptoms of stress, anxiety, and aggression. He underwent microsurgical vasovasostomy, and vassal patency was confirmedby return of spermat
We suggest the hybrid model for the description of the dipole spreading widths, in which the strength function is built on the one-phonon strength distribution folded with the energy-dependent Lorentzian. Its energy dependence is brought about by (i) the energy-dependent smearing parameter and (ii) the energy-dependent shift of the one-phonon states. These variables are estimated by means of the t
In this paper, channel measurement campaigns at center frequency of 72 GHz with 2 GHz bandwidth conducted by Huawei company are introduced. The transmitter and receiver make use of similar horn antennas which are rotated step by step in the directional domains to capture the frequency spectra of spatial channels in line-of-sight and non-line-of-sight scenarios of indoor environments. The data is a
In this paper, a measurement campaign for massive multiple-input multiple-output (MIMO) channel characterization in both line-of-sight (LoS) and non-LoS outdoor environments is introduced. The measurements are conducted at the center frequency of 15 GHz with a bandwidth of 4 GHz. A virtual 40× 40 planar antenna array formed by stepping a vertically-polarized bi-conical omni-directional antenna (OD
In this contribution, a measurement campaign for high- speed-train (HST) channel is introduced where the down- link signals of in-service Long Time Evolution-Advanced (LTE-A) network deployed along the HST railway between Beijing to Shanghai are acquired. Channel impulse responses (CIRs) are extracted from received signals, and concatenated power delay profiles (CPDPs) are illustrated. According t
Millimeter-wave with ultrawide bandwidth available and ability to pack massive number of antennas in a small area is considered the key enabler for future generation communication systems. Accurate understanding and modeling of the ultrawideband propagation channel with large-scale array configuration is essential. In this contribution, a realistic spherical-propagation signal model considering th
In this paper, a recently conducted measurement campaign for vehicle-to-vehicle (V2V) propagation channel characterization is introduced. Two vehicles carrying a transmitter and a receiver, respectively, have been driven along an eight-lane road with heavy traffic. The measurement was conducted with 100 MHz signal bandwidth at a carrier frequency of 5.9 GHz. Channels are observed consisting of two
The operating mechanisms of a planar patch antenna with a parasitic strip is analyzed in this paper. The patch antenna uses a thin parasitic strip to realize beam deflection, which facilitates switchable beam. The beam deflection effect of the parasitic strip can be explained by using characteristic mode analysis (CMA). Specifically, the parasitic strip introduces a new mode that interacts with a
This study investigates how related variety in the regional employment mix affects the innovation output of a region. Departing from the idea of recombinant innovation, previous research has arguedthat related variety enhances regional innovation as inter-industry knowledge spillovers occur more easily between different but cognitively similar industries. This study combines a
Who produces scientific and technical knowledge these days? What type of knowledge is being produced and for what purposes? Why are firms and governments funding research and development? This chapter studies the role of knowledge production (especially R&D activities) in the innovation process from an innovation system perspective. It examines how governments and public agencies in different
Objective: Novel, highly effective disease-modifying therapies have revolutionized multiple sclerosis (MS) care. However, evidence from large comparative studies on important safety outcomes, such as cancer, is still lacking. Methods: In this nationwide register-based cohort study, we linked data from the Swedish MS register to the Swedish Cancer Register and other national health care and census
