Protein dynamical transition vs. liquid-liquid phase transition in protein hydration water
2013
In this work, we compare experimental data on myoglobin hydrated powders from elastic neutron scattering, broadband dielectric spectroscopy, and differential scanning calorimetry. Our aim is to obtain new insights on the connection between the protein dynamical transition, a fundamental phenomenon observed in proteins whose physical origin is highly debated, and the liquid-liquid phase transition (LLPT) possibly occurring in protein hydration water and related to the existence of a low temperature critical point in supercooled water. Our results provide a consistent thermodynamic/dynamic description which gives experimental support to the LLPT hypothesis and further reveals how fundamental …

BIODEGRADACJA ZWIĄZKÓW FOSFONOWYCH PRZEZ GRZYBY
2020
Phosphonates are the group of organophosphorus compounds, which are characterized by the presence of covalent bond(s) between carbon and phosphorus atom in their structure. Both; the natural and synthetic phosphonic compounds, are encountered in various ecosystems, however because of their wide range of applications, the latter ones are considerably more frequently discussed. Regarding the broad spectrum of biological activity, capability to chelate metal cations and environmental stability of direct carbon to phosphorus bond under physiological conditions, phosphonic compounds found a variety of applications e.g. as pesticides, drugs, anticorrosive agents, additives to surfactants and flam…
Significance of immunohistochemistry biomarkers in prediction of malignant transformation of oral lichen planus
2022
Background: Oral lichen planus (OLP) is a chronic inflammatory disorder with increased risk for malignant transformation. Biomarker validation is a pivotal step in moving newly discovered biomarkers towards clinical implementation. We performed a systematic review of studies on biomarkers related to OLP, wherein biomarkers have been described in at least two independent studies. Our aim was to determine whether any of these biomark-ers might be promising in predicting the increased risk of malignant transformation of OLP. Material and Methods: We searched the following databases until August 2021: PUBMED, EMBASE, and Web of Science. Due to high heterogeneity, a qualitative rather than quant…
La tecnología Blockchain en la construcción de espacios económicos de impacto social positivo
2021
espanolEste trabajo realiza un estudio del universo de la tecnologia blockchain y su aplicacion en el mundo del siglo XXI a traves del analisis de diferentes espacios virtuales construidos con ella. El objetivo ultimo de este analisis es valorar y comprender las posibilidades que esta tecnologia aporta en la construccion de procesos con un alto impacto social y/o ambiental. A tal efecto, se lleva a cabo una investigacion exploratoria a traves del estudio de casos significativos o pioneros desde una perspectiva socio-tecnologica. Los resultados concluyen que, si bien en sus origenes la tecnologia blockchain se estructuro con una marcada perspectiva financiera, el transcurso del tiempo ha dem…
Phantoms Used for Mapping of Skin Chromophores by Multi-spectral Imaging
2014
Skin phantoms can be used for better understanding of diffuse reflectance imaging of skin. In this study, skin phantoms of hemoglobin, bilirubin and melanin were developed and studied for possibilities to calibrate chromophore concentration values.
Scaling symmetries and optimization of the refractive index profile in optical fibers
2019
The optical fiber refractive index profile has a significant role in the optical devices fabrication like fiber Bragg gratings (FBG) and acousto-optic devices and the way guided light interacts in the presence of external factors like strain, stress or even bends. The analysis of the fiber profile gets to be feasible throughout understanding the properties of the optical guided modes such as the effective index, group index, and the chromatic dispersion. Taking a broader look at previous publications that use standard commercial optical fibers, it becomes noticeable that the ideal core-cladding step index profile gives incompatible results when it comes to the experimental versus the simula…
Transformation of the agricultural financial system in the age of globalisation
2017
The paper is an attempt to address the advantages and risks connected with the wave of financial globalisation, with a focus on its impact on financial policy in European agriculture. The aim of the paper is to identify the basic conditions of the functioning and change of the financial system of agriculture under the conditions of the globalisation of financial markets. Financial globalisation, also referred to as financial integration or openness, is understood as an increase in global ties and interdependences caused by capital flows. Potentially, globalisation can bring a lot of benefits, which are manifested in an acceleration of economic growth and decreased fluctuation in consumption…
A Power Sector in Transition Understanding Transition Towards a Cleaner Grid and how Distributed Energy Resources Affect the Design and Operation of …
2018
Important changes in the supply and the demand side of electricity apparatus are now underway, triggered by a combination of drivers dramatically affecting the transmission sector of power systems: greenhouse gas emissions, distributed generation, energy efficiency and the full integration of the European energy market. A variety of accelerating factors - including active consumer, aggregators, energy storage, e-vehicles, etc..- are creating a new era for the many stakeholders, incl. system operators, regional entities, industry and consumer organizations, producers or their trade bodies, Regulators, public decision makers and the society at large. Entraining this background, ENTSO-E and th…
Benefits and Challenges of Digitalization: An Expert Study on Norwegian Public Organizations
2021
The implementation of and research on digital transformation in the context of public organizations have increased substantially in the past few years. A wide range of drivers, benefits, and challenges associated with digitalization have been suggested in the literature. However, these suggestions appear fragmented and disconnected, and do not offer a clear overview of the main drivers, challenges, and benefits. Moreover, research in this regard in the Norwegian and Scandinavian contexts is lacking. Therefore, there is a need to clarify the drivers, benefits, and challenges of digital transformation. To address this need, seven Norwegian public organizations were investigated by gathering d…
