In a future fossil-free circular economy, the petroleum-based plastics industry must be converted to non-fossil feedstock. A known alternative is bio-based plastics, but a relatively unexplored option is deriving the key plastic building blocks, hydrogen and carbon, from electricity through electrolytic processes combined with carbon capture and utilization technology. In this paper the future dem

Structural change consists of the long-term changes in the sectoral composition of output and employment. We introduce a structural change perspective to the study of income inequality in 27 countries of the developing world for the period 1960–2010. The service sector has become the main employer, but the agricultural sector is central to the income distribution because poverty is mostly rural, a
Clinical education is a significant part of nursing education on all levels of education. A lot of effort is made by educational providers to prepare the students for their clinical placement (Levett-Jones et al., 2015). At best, this is a shared enterprise, involving representatives from the profession in creating a useful clinical placement for the students. However, the strain on clinical nurse
This article analyses some young men’s specific ways of retelling victims’ experience when the perpetrators have an immigrant background. In qualitative interviews with twenty young men, fear of being seen as intolerant was distinguished by their expressive caution. This involved using various aligning actions: presenting disclaimers and accounts, but also in terms of hesitant speak, re-takes and This article analyses some young men’s specific ways of retelling victims’ experience when the perpetrators have an immigrant background.

Scholarly communication is complex. The clarification of concepts like “academic publication”, “document”, “semantics” and “ontology” facilitates tracking the limitations and benefits of the media of the current publishing system, as well as of a possible alternative medium. In this paper, requirements for such a new medium of scholarly communication, labeled Scholarly Network, have been collected
In this paper, optimal resource allocation policies are characterized for wireless cognitive networks under the spectrum leasing model. We propose cooperative schemes in which secondary users share the time-slot with primary users in return for cooperation. Cooperation is feasible only if the primary system's performance is improved over the non-cooperative case. First, we investigate a scheduling
It is well known that Max-Weight type scheduling algorithms are throughput optimal since they achieve the maximum throughput while maintaining the network stability. However, the majority of existing works employing Max-Weight algorithm require the complete channel state information (CSI) at the scheduler without taking into account the associated overhead. In this work, we design a Scheduling and
We investigate the network stability problem when two users are scheduled simultaneously. The key idea is to simultaneously transmit to more than one users experiencing different channel conditions by employing hierarchical modulation. For two-user scheduling problem, we develop a throughput-optimal algorithm which can stabilize the network whenever traffic load is stabilizable (i.e., it is within
The main limitation of operating sensor networks autonomously is the finite battery capacity of sensor nodes. Sensors are usually operated at low duty cycle; that is, they remain in active mode for short duration of time, in order to prolong the network lifetime. However, operating at low duty cycle may result in significant performance degradation in system operation. Hence, in this work, we quan
Stroke is a leading cause of disability and currently lacks effective therapy enabling long-term functional recovery. Ischemic brain injury causes local inflammation, which involves both activated resident microglia and infiltrating immune cells, including monocytes. Monocyte-derived macrophages (MDMs) exhibit a high degree of functional plasticity. Here, we determined the role of MDMs in longterm
We demonstrate that an undamped few-body precursor of the Higgs mode can be investigated in a harmonically trapped Fermi gas. Using exact diagonalization, the lowest monopole mode frequency is shown to depend nonmonotonically on the interaction strength, having a minimum in a crossover region. The minimum deepens with increasing particle number, reflecting that the mode is the few-body analogue of
The glycocalyx is a carbohydrate-rich layer that lines the luminal side of the vascular endothelium. Its soluble components exist in a dynamic equilibrium with the bloodstream and play an important role in maintaining endothelial layer integrity. However, the glycocalyx can be easily damaged and is extremely vulnerable to insults from a variety of sources, including inflammation, trauma, haemorrha
Purpose: To investigate if plasma cytokine concentrations predict a beneficial response to corticosteroid treatment in septic shock patients. Methods: A cohort of septic shock patients in whom a panel of 39 cytokines had been measured at baseline (n = 363) was included. Patients who received corticosteroids were propensity score matched to non-corticosteroid-treated patients. An optimal threshold
