Profile, predispositions and preferences of the UNIGS e-students
W pocz膮tkowej fazie swojego rozwoju edukacja w zakresie GIS sprowadza艂a si臋 g艂贸wnie do wykszta艂cenia specjalist贸w dysponuj膮cych wiedza techniczna. Obecnie, masowe wkroczenie GIS w sfer臋 us艂ug wymaga r贸wnie偶 znajomo艣ci zagadnie艅 biznesu. W pracy podj臋to pr贸b臋 odpowiedzi na pytania o to, czy oferta kszta艂cenia w zakresie GIS nad膮偶a za g艂贸wnym trendem rozwoju technologii oraz jak z tej oferty korzystaj膮 studenci. Dokonano analizy profilu, predyspozycji i preferencji student贸w Studi贸w Podyplomowych Systemy Informacji Geograficznej UNIGIS, prowadzonych na Uniwersytecie Jagiello艅skim, w kontek艣cie mo偶liwo艣ci, jakie te studia oferuj膮. Badania oparto na informacjach zgromadzonych w czasie rekrutacji oraz na wynikach ankiet przeprowadzonych w艣r贸d student贸w. Studia UNIGIS kszta艂tuj膮 umiej臋tno艣ci dostrzegania mo偶liwo艣ci zastosowania GIS i kierowania zespo艂em ludzi posiadaj膮cych wiedze techniczna w tym zakresie. Studenci UNIGIS nabywaj膮 r贸wnie偶 umiej臋tno艣ci nauki, pracy i wsp贸艂pracy online oraz radzenia sobie z du偶膮 ilo艣ci膮 informacji. Dodatkowo za sprawa przynale偶no艣ci do globalnej spo艂eczno艣ci w ramach sieci UNIGIS
International Association maj膮 mo偶liwo艣膰 nawi膮zywania kontakt贸w profesjonalnych w Polsce i zagranic膮. Niemniej jednak, wyniki przeprowadzonej analizy dowodz膮, 偶e mimo obecno艣ci nowych tendencji rozwoju technologii GIS w ofercie studi贸w UNIGIS, nie znajduj膮 sie one jeszcze w centrum zainteresowania os贸b podejmuj膮cych te studia.In its preliminary development phase, GIS education has focused mainly on delivering specialists furnished with technical knowledge. Currently, widespread presence of GIS in the field of www services requires them to be familiar with the business-related issues. This study attempts to give the answer to some questions. Does the GIS educational offer keep pace with the main technology development trend and how do students make use of this offer? The analysis of the profile, predispositions and preferences of the students attending the Postgraduate Studies in Geographic Information Systems UNIGIS at the Jagiellonian University was carried out in comparison with the study prospects. The research was based on the information retrieved during the enrolment and on the results of survey given out to students.

Rapeseed biofuel. Preparation of raw material for biodiesel production in agricultural household conditions. Pilot methanolysis processes
Scharakteryzowano olej rzepakowy jako surowiec do produkcji biodiesla i opisano etapy procesu transestryfikacji. Oceniono metody wydobywania oleju rzepakowego poprzez t艂oczenie w warunkach gospodarstwa rolnego i scharakteryzowano oleje pod wzgl臋dem przydatno艣ci do reakcji metanolizy (zawarto艣膰 fosforu, LK, LOO, sk艂ad kwas贸w t艂uszczowych). Przeprowadzono wst臋pne laboratoryjne reakcje transestryfikacji i na ich podstawie wytypowano parametry reakcji w skali 膰wier膰technicznej. Stopie艅 konwersji oleju do estr贸w metylowych kwas贸w t艂uszczowych (EMKT) oznaczano poprzez pomiar wsp贸艂czynnika za艂amania 艣wiat艂a.Rapeseed oil has been characterized as a raw material in biodiesel production and stages of this process have been described. An evaluation of methods of extracting oil from rapeseed has been performed. The oil has been evaluated on its usefulness for methanolysis process (phosphorus content, fatty acid composition, acid and peroxide values). Preliminary transesterification reactions have been conducted on a laboratory scale and, based on the obtained results, parameters for household scale process have been chosen. The stage of oil-into-FAME conversion has been determined through refractive index measurement
Electronic Cigarettes and Head and Neck Cancer Risk-Current State of Art
Simple Summary The risk of developing cancer is always higher for tobacco smokers than for non-smokers. Electronic cigarettes (e-cigarettes) have become increasingly popular in the last decade and are considered less harmful than traditional tobacco products, due to the lower content of toxic and carcinogenic compounds. However, this is still a controversial issue. This paper contains a review of previous reports on the composition of e-cigarettes and their impact on the pathogenesis and risk of head and neck cancer (HNC). The authors reviewed articles on both toxic and carcinogenic compounds contained in e-cigarettes and their molecular and health effects on the upper respiratory tract in comparison to traditional tobacco cigarettes. In conclusion, the studies discussed in the review strongly suggest that more long-term studies are needed to better address the safety of e-cigarettes. E-cigarettes have become increasingly popular in the last decade and are considered less harmful than traditional tobacco products due to the lower content of toxic and carcinogenic compounds. However, this is still a controversial issue. This paper contains a review of previous reports on the composition of e-cigarettes and their impact on the pathogenesis and risk of head and neck cancer (HNC). The objective of the review was to compare the molecular and health effects of e-cigarette use in relation to the effects of traditional cigarette smoking in the upper respiratory tract, and to assess the safety and effect of e-cigarettes on HNC risk. A review for English language articles published until 31 August 2020 was made, using a PubMed (including MEDLINE), CINAHL Plus, Embase, Cochrane Library and Web of Science data. The authors reviewed articles on both toxic and carcinogenic compounds contained in e-cigarettes and their molecular and health effects on the upper respiratory tract in comparison to tobacco cigarettes. The risk of developing head and neck squamous cell carcinoma (HNSCC) remains lower in users of e-cigarettes compared with tobacco smokers. However, more long-term studies are needed to better address the safety of e-cigarettes.Peer reviewe

Insights into the Inhibition of the p90 Ribosomal S6 Kinase (RSK) by the Flavonol Glycoside SL0101 from the 1.5 脜 Crystal Structure of the N鈥慣erminal Domain of RSK2 with Bound Inhibitor
The p90 ribosomal S6 family of kinases (RSK) are potential
drug
targets, due to their involvement in cancer and other pathologies.
There are currently only two known selective inhibitors of RSK, but
the basis for selectivity is not known. One of these inhibitors is
a naturally occurring kaempferol-伪-l-diacetylrhamnoside,
SL0101. Here, we report the crystal structure of the complex of the
N-terminal kinase domain of the RSK2 isoform with SL0101 at 1.5 脜
resolution. The refined atomic model reveals unprecedented structural
reorganization of the protein moiety, as compared to the nucleotide-bound
form. The entire N-lobe, the hinge region, and the 伪D-helix
undergo dramatic conformational changes resulting in a rearrangement
of the nucleotide binding site with concomitant formation of a highly
hydrophobic pocket spatially suited to accommodate SL0101. These unexpected
results will be invaluable in further optimization of the SL0101 scaffold
as a promising lead for a novel class of kinase inhibitors
Biotechnological aspects of cold-active enzymes
Cold-adapted enzymes produced by organisms inhabiting permanently low temperature environments are typically characterized by a high activity at low to moderate temperatures and a poor thermal stability. Such characteristics make these enzymes highly attractive for various applications where they can enable more efficient, cost-effective, and environmentally friendlier processes than higher temperature-adapted enzymes. In this chapter, the biotechnological aspects of coldadapted enzymes and their application in industry are reviewed and discussed with a focus on cleaning/detergents, food and beverages, molecular biology, biomedicine, pharmaceuticals, cosmetics, textiles, biofuels, and materials applications.s T.C. is supported by the Fundac赂~ao para a Cie藛ncia e a Tecnologia (FCT), the
