  Przewoźną instalację wyposażoną w napowietrzane reaktory cyklonowe zbadano pod kątem przydatności w procesie ciągłego odpędzania i absorpcji HCN z kopalnianych wód procesowych. Zastosowanie reaktora cyklonowego pozwoliło na ponad 99% absorpcję HCN podczas jednego przejścia fazy gazowej przez reaktor. Natomiast uzyskana efektywność odpędzania HCN, zależna przede wszystkim od stałej Henry'ego, przekroczyła 40% dla jednego przejścia...

  - IEEE Communications Surveys and Tutorials - Year 2021

  In order to meet their stringent dependability requirements, most modern packet-switched communication networks support fast-recovery mechanisms in the data plane. While reactions to failures in the data plane can be significantly faster compared to control plane mechanisms, implementing fast recovery in the data plane is challenging, and has recently received much attention in the literature. This survey presents a systematic,...

  - Science Advances - Year 2017

  Entanglement is one of the most puzzling features of quantum theory and a principal resource for quantum information processing. It is well known that in classical information theory, the addition of two classical information resources will not lead to any extra advantages. On the contrary, in quantum information, a spectacular phenomenon of the superadditivity of two quantum information resources emerges. It shows that quantum...

• Export diversification and dependence on natural resources

  Publication

  • Z. H. Zarach

  - ECONOMIC MODELLING - Year 2023

  Low export diversification is a risk-augmenting factor for many countries dependent on natural resources. The literature tends to focus on the growth effects of resource dependence (‘resource curse’ debate) while not much is known on how it affects the variety of non-resource exports. To quantify this effect we decompose the relative Theil index using product-level export data from 160 countries over the time period 1996–2018....

  - ACS Applied Energy Materials - Year 2021

  Degradation of perovskite solar cells (PSCs) is often found to be partially or fully reversible when the cells are allowed to recover in the dark. Unlike the dynamics of degradation, knowledge about the dynamics of PSC cell recovery is very limited. Here, we demonstrate that the PSC recovery strongly depends on the electrical bias conditions during the light-induced degradation and that it can be manipulated by applying an external...

  Failures in optical networks are inevitable. They may occur during work being done for the maintenance of other infrastructures, or on a larger scale as the result of an attack or large-scale disaster. As a result, service availability, an important aspect of Quality of Service (QoS), is often degraded. Appropriate fault recovery techniques are thus crucial to meet the requirements set by the Service Level Agreements (SLAs) between...

  The conversion of a waste heat energy to electricity is now becoming one of the key points to improve the energy efficiency in a process engineering. However, large losses of a low-temperature thermal energy are also present in power engineering. One of such sources of waste heat in power plants are exhaust gases at the outlet of boilers. Through usage of a waste heat regeneration system it is possible to attain a heat rate of approximately...
