Opis:
The number, magnitude, sophistication, frequency and impact of incidents are increasing and present a major threat to the functioning of network and information systems. As a result, incidents can impede the pursuit of economic activities in the internal market, generate financial loss and cause significant damage to the Union’s economy and society. Therefore, effectiveness in cybersecurity is becoming increasingly vital for the proper functioning of the internal market. On December 14, 2022, the EU legislator adopted a directive on measures for a high common level of cybersecurity across the Union, called the NIS 2 Directive. The new NIS 2 directive aimed to lay down mechanisms for effective cooperation among the responsible authorities in each Member State and to update the list of sectors and activities subject to cybersecurity obligations. The article reviews the entities involved in the policy of ensuring the security of network and information systems in the light of the NIS 2 directive.

Opis:
The constantly increasing need of environmental protection causes the growth of demand on manufacture of environment-friendly packaging which would prolong the shelf-life of the products inside, and which would be produced from solid and sustainable packaging materials. It is important nowadays to avoid food wastage and contamination of the environment. The answer to the mentioned requirements may be found in the innovative approaches such as edible films, biopolymers or the application of additives, allowing longer use of food. Active packagings create a new path of food packaging, concentrated on creation of multi-functional system via formulation of active substances in polymer matrix of polymer packaging. The discussed packaging has a great potential for the application in contact with food due to their positive effect on ecological problems and other unique properties. The aim of the present paper is to discuss the modern solutions in production of biopolymers, employed in production of food packaging and development of more and more functional packaging. In the review, the activities connected with the creation of more ecological and functional, environment-friendly packagings have been submitted and the related barriers have been indicated.
Rosnąca z każdym rokiem potrzeba ochrony środowiska powoduje zwiększające się zapotrzebowanie na produkcję opakowań przyjaznych dla środowiska i przedłużających ich termin do spożycia, trwałych i ze zrównoważonych materiałów opakowaniowych. Ważne jest dzisiaj aby unikać marnowania żywności i zanieczyszczenia środowiska. Odpowiedzią na te wymagania są innowacyjne podejścia, takie jak: folie jadalne, biopolimery czy zastosowanie dodatków, które pozwolą dłużej korzystać z żywności. Opakowania aktywne to nowa ścieżka pakowania żywności, koncentrująca się na tworzeniu wielofunkcyjnego systemu poprzez formułowanie substancji aktywnych w matrycach polimerowych opakowań. Opakowania takie mają ogromny potencjał do zastosowania w kontakcie z żywnością ze względu na ich pozytywny wpływ na problemy ekologiczne i inne unikalne właściwości. Celem niniejszego artykułu jest przedstawienie nowoczesnych rozwiązań w wytwarzaniu biopolimerów wykorzystywanych do produkcji opakowań do żywności oraz tworzeniu opakowań bardziej funkcjonalnych. W przeglądzie pokazano działania związane z powstawaniem coraz bardziej ekologicznych i funkcjonalnych opakowań przyjaznych dla środowiska oraz wskazano jakie bariery z tym są związane.

Opis:
This article aims to answer the question of the biographical meaning of the pandemic in the experiences of so-called “essential workers” who performed their duties in the first line of struggle with the consequences of the COVID-19 health crisis. The analysis of workers’ experiences helps us contribute to the ongoing debates on the role of macro-level events in autobiographical storytelling and the discussion on biographical turning points in sociology. The empirical analysis is based on a collection of more than 80 biographical narrative interviews in healthcare, social care, education, and logistics, from which we selected two stories of the pivotal significance of the pandemic crisis for biographical change for analysis. Biographical analysis makes it possible to describe which conditions are conducive to the inclusion of the pandemic in the main biographical story as a turning point.

Opis:
Currently, climate change is disrupting life on Earth by causing imbalances in the biosphere. This work aimed to evaluate the impact of climate change on the content of primary and secondary metabolites and the yield of essential oil of Rosmarinus officinalis. Thus, the results of the conducted experiment show that the content of primary metabolites decreased with increasing temperature and decreasing precipitation along the experiment(proteins from 7.61% to 7.14%, carbohydrates from 6.92% to 5.64%, fats from 1.48% to 1.29% and dietary fiber from 4.96% to 4.22% and mineral composition: Ca from 7.67% to 5.98%, Mg from 8.61% to 7.01%, Fe from 7.53% to 7.21% and Mn from 6.85% to 3.97%), and the content of secondary metabolites increased in the second year when increasing the temperature by 5 °C and water stress by 50% (coumarin from 6.59% to 10.99%, saponins from 7.15% to 8.46%, tannin from 3.92% to 5.95%, alkaloids from 6.69% to 15.62% and flavonoid from 8.02% to 15.75%),but in the fourth year when the temperature continued to increase and water stress was 75% the content of secondary metabolites decreased (coumarin from 10.99% to 8.27%, saponins from 8.46% to 7.87%, tannin from 5.95% to 4.85%, alkaloids from 15.62% to 10.68% and flavonoid from 15.75% to 11.36%)and the same results were obtained for the yield of essential oil which increased in the second year and decreased in the fourth year. This GC analysis of the three essential oil samples shows that the majority of compounds in the three essential oils studied are cineole (S1:45.98%, S2:55.36%, S3:43.08%) followed by camphor (S1:17.44%, S2:21.44%, S3:21.56%) and Alpha-pinene (S1:9.30%, S2:8.34%, S3: 9.17%) and other compounds in low percentage.

Opis:
In the study, the influence of distillation time as well as distillation apparatus on the chemical composition and quality of lavender (Lavandula angustifolia Mill.) essential oil were investigated. Two different types of distillation apparatuses: Deryng (popular in Poland) and Clevenger-type (recommended by European Pharmacopoeia) were used for the isolation of the essential oil from dried lavender flowers (Lavandulae flos). Moreover, different distillation times (2, 3 and 4 hours) were also applied. The chemical composition of the isolated oils, determined by gas chromatography coupled with mass spectrometry (GC-MS), revealed the dominance of linalool (11.55–17.19%) and linalyl acetate (12.84–16.78%) in the all analyzed samples. Other important constituents were: caryophyllene oxide (5.66–7.35%), lavandulyl acetate (4.64–5.40%) and borneol (4.62–5.51%). On the basis of the obtained data it was proved that the distillation time and distillation apparatus affect the amounts of some constituents in the lavender oil.

Analizuję retorykę sporu między Karolem Irzykowskim i Witkacym, traktując polemiczne wypowiedzi jako wyraz skrywanych resentymentalnych uprzedzeń. Spór ten interpretuję jako pojedynek dwóch nieuznanych intelektualistów, oskarżających się o anachronizm i przyznających sobie miano prekursora. W psychomachii Irzykowskiego i Witkacego podkreślam nieustanne wykraczanie obu pisarzy poza normy etyczne artystycznego sporu, przez nich samych postulowane.
This essay offers an analysis of the rhetoric of the dispute between Irzykowski and Witkacy that takes into account both artists’ strong statements of opinions as an indication of their hidden recurring resentments. In the essay, the dispute is interpreted as a duel between two unrecognised intellectuals accusing each other of anachronisms and honouring themselves with a label of a precursor. What is more, the author of the essay points out how the nature of this psychomachy-like dispute manifests itself with a constant violation of by and large accepted ethical norms of an artistic dispute of which the two were eager proponents.

Opis:
Zaprezentowane opracowanie jest komentarzem do niepublikowanego wyroku c. Emanuele Saturnino da Costa Gomes z 1 marca 2022 r. Autor szczegółowo omówił strukturę omawianego wyroku: przebieg sprawy, motywy prawne oraz motywy faktyczne. Prezentowany wyrok jest przykładem coraz częściej spotykanej w Polsce praktyki apelo- wania od wyroków w pierwszej instancji wprost do Trybunału Roty Rzymskiej. Zjawisko to, niespotykane wcześniej w takiej skali, może rodzić pytanie o ratio legis normy kan. 1444 § 1 n. 1 KPK w kontekście normy kan. 1438 n. 1-2 KPK, czyli o porządek stopni apelacji. Nie negując bowiem prawa wiernych do rozpatrywania swoich spraw w Stolicy Świętej, a nawet przeniesienia ich tam na każdym stopniu postępowania i w każdym stadium sporu, podkreślić należy, że normalnym trybunałem apelacyjnym dla diecezji sufragalnych jest trybunał metropolity, a dla trybunału metropolity inny sąd diecezjalny, który zaaprobowała Stolica Apostolska. Apelowanie więc od wyroków pierwszej instancji wprost do Trybunału Roty Rzymskiej wydaje się być trybem ekstraordynaryjnym, domagającym się jakichś szczególnych racji. Sprowadzanie bowiem trybunału papieskiego do roli zwyczajnego sądu drugiej instancji może rodzić wątpliwości natury systemowej.  
The presented study is a commentary on the unpublished judgment of c. Emanuele Saturnino da Costa Gomes of March 1, 2022. The author discussed in detail the structure of the judgment in question: the course of the case, legal and factual reasons. The presen- ted judgment is an example of the increasingly common practice in Poland of appealing against judgments in the first instance directly to the Tribunal of the Roman Rota. This phenomenon, unprecedented on such a scale, may raise the question of the ratio legis of can. 1444 § 1 n. 1 CIC/83 in the context of can. 1438 n. 1-2 CIC/83, that is, the order of the degrees of appeal. Without denying the right of the faithful to consider their cases in the Holy See, and even transfer them there at every stage of the proceedings and at every stage of the dispute, it should be emphasized that the normal appellate tribunal for suffragal dioceses is the metropolitan tribunal, and for the metropolitan tribunal another diocesan court, which approved by the Holy See. Therefore, appealing against the judgments of the first instance directly to the Tribunal of the Roman Rota seems to be an extraordinary procedure, demanding some special reasons. Reducing the papal tribunal to the role of an ordinary court of second instance may raise doubts of a systemic nature.

Opis:
The needles of the Aleppo pine (Pinus halepensis) (PA) are very abundant in the forest of the National Park of Tazekka (Ta-za-Morocco) and are unexploitable. Moreover, they constitute a potential danger because they facilitate the outbreak of wildfires. To solve this problem, we have considered turning these needles into a biomaterial that could be used as raw material for different uses, such as wastewater treatment. The biomaterial of the Aleppo pine is obtained from its needles which are harvested in spring, dried, cut, crushed, and sieved. The powder obtained is analyzed before and after the extraction of essential oil. The physicochemical and spectroscopic analyses show that this biomaterial is porous, hygroscopic, slightly acidic, moderately moist, and not very conducive. Its average density in the anhydrous state is 0.6. It is rich in carbon (79.91%) and oxygen (18.91%) in the form of aromatic compounds and ketone imprints; thus, relating the presence of cellulose, pectin, lignin, and hemicellulose. Its composition in mineral elements (Na, Mg, Ca, K, Cl, S) is deficient. Gas chromatography-mass spectrometry (GC-MS) analysis of the oils extracted from the needle powder relates that it is a complex mixture of bioactive compounds such as mono-terpenoid α and β-pinene hydrocarbons. These results show that our biomaterial can be used as an adsorbent in wastewater treatment and the extracted essential oils can be used in the pharmacological, agro-food field.

Autor przedstawia i komentuje negatywny wyrok Roty Rzymskiej c. Verginelli z 25 marca 2011 r. w sprawie o nieważność małżeństwa z powodu incapacitas assumendi po stronie mężczyzny (kan. 1095, n. 3 KPK/83), rozpoznawanej w trzeciej instancji (wyrok negatywny w pierwszej, pozytywny w drugiej). O ile w pierwszej instancji, gdzie instrukcja dowodowa okazała się dość obszerna (zeznania stron, zeznania siedmiu świadków, opinia biegłego), o tyle w drugiej instancji uzupełniono ją jedynie opinią biegłego sporządzoną na podstawie akt sprawy. Na stopniu rotalnym ograniczało się to do dotychczas zebranego materiału. Podstawa prawna wyraźnie wskazuje na zgodę małżeńską (actus humanus), a także możliwość jej wyrażenia. Ponens słusznie podkreślił, że mając na uwadze wiele aspektów tej zdolności, ważne jest przede wszystkim odniesienie jej do poważnych przyczyn psychologicznych, które uniemożliwiają podmiotowi zawarcie konsensusu małżeńskiego. W uzasadnieniu faktycznym wyroku turnus rotalny ocenił materiał dowodowy zebrany w dwóch pierwszych instancjach. Pewnym mankamentem był tu brak zeznań pozwanego w drugiej instancji oraz niestawiennictwo na badanie biegłego. Znaczącym było odrzucenie w wyroku rotalnym opinii biegłego (sporządzonej w drugiej instancji) jako niewspółbrzmiącej z innymi dowodami.
The author presents and comments on the (negative) sentence of the Roman Rota, c. Verginelli of March 25, 2011, in the Plocen. case for nullity of a marriage due to incapacitas assumendi (can. 1095, n. 3 CIC/83), heard in the third instance (negative in the first instance, positive in the second); it was about the man's inability. While in the first instance, where the evidence instruction turned out to be quite extensive (testimonies of the parties, testimonies of seven witnesses, expert opinion), in the second instance it was only supplemented by an expert opinion prepared on the basis of the case files; in the rotational instance, it was confined to the material gathered so far. The legal grounds clearly show the marriage consent (actus humanus), as well as the ability to obtain it. Ponens rightly emphasized that, bearing in mind many aspects of this ability, it is above all important to relate it to serious psychological reasons that make it impossible for the subject to form a marriage consensus. In the factual grounds of the judgment, the Roman Rota assessed the evidence gathered in the first two instances. A certain drawback here was the lack of the defendant's testimony in the second instance and the failure to appear for the expert examination. Something significant was the judgment's rejection of the expert opinion (in the second instance) as inconsistent with other evidence by the rotating camp.

Leather products provide an ideal environment for microbial growth. In order to prevent the appearance and spread of various types of microorganisms, it is treated with selected biocides and even essential oils. The aim of this paper was to investigate the antifungal activity of selected essential oils applied to finished chromium tanned leather which is intended for leather fancy products. Antifungal activity was evaluated according to the PN-EN 14119: 2005 standard. Four finished chromium tanned leathers were tested, each of which was soaked in the following essential oils: tea tree essential oil at a concentration of 1, 2 and 5% and thyme essential oil at concentration of 1, 2 and 5%. The results obtained indicated that leather finishing with thyme essential oil showed the antimicrobial activity against Aspergillus niger, Chaetomium globosum and Candida albicans strains. The application of 5% thyme essential oil to leather samples inhibited the growth of all strains tested. Using tea tree essential oil on leather samples showed a antimicrobial effect only against Candida albicans. The application of essential oils in the leather finishing process may be an alternative to biocides used in the tanning industry.

This research aimed to measure the impact of provenance on the yield, chemical profile and antimicrobial activity of Rosmarinus officinalis essential oil (EO) collected from cultivated and wild plants from two different regions in Morocco (Fez and Figuig). The chemical composition analysis was accomplished utilizing the GC-MS techniques. Sixteen compounds were identified in the EO of both samples, dominated by 1,8-cineole (32.18%), camphor (16.20%) and α-pinene (15.40%) in cultivated type. The α-pinene (51.19) presents the majority compound in the rosemary samples collected from the wild populations.The antimicrobial activity was investigated by using the broth dilution methods against yeast, four bacterial strains and two molds. Rosemary aerial part provided EO with the highest yield and comes from Figuig. The GC-MS analysis demonstrated the existence of two chemotypes of oils: α-pinene as well as 1,8-cineole/camphor/α-pinene. Both EOs showed good antimicrobial activity against all microbial strains. The essential oil produced by Fez plants was the most effective against the selected microorganisms having MIC values of 0.315–2.5 mg/L.

Background. During the recent years, appropriate attention has been paid to the oxidative stress which damages the body’s cells, proteins, and DNA. Therefore, the need of antioxidants becomes a therapeutic and preventive priority. In addition, microbial infections also constitute a public health problem. Objective. To find efficient, reliable and safe alternatives sources to synthetic antioxidants, antibiotics and antifungals drugs. Materials and methods. Extract and essential oil of Psidium guajava were screened for their antioxidant and antimicrobial activities against gram positive bacteria (Enterococcus faecalis and Staphylococcus aureus), gram negative bacteria (Citrobacter freundii, Escherichia coli and Pseudomonas sp) and fungi (Candida albicans,Candida tropicalis and Cryptococcus neoformans), as well as to determine the functional groups of phytochemicals present in the essential oil by Fourier transform infrared spectroscopy (FTIR). Results. The results indicate that P. guajava leaves extract demonstrated very high antioxidant activity and P.guajava essential oil showed the highest polyphenols content. The antioxidant capacity showed a significant negative linear correlation to total polyphenolic content (TPC) with Pearson’s correlation coefficients. P. guajava essential oil shows high antibacterial and antifungal activity against all the studied bacteria and fungi.The FTIR analysis of P. guajava essential oil showed the presence of several functional groups (ethers, esters, ketones, terpenes, alkanes, aldehydes, aromatic hydrocarbons, alcohols, and phenols). The relationship between the chemical composition and antimicrobial activity of P.guajava essential oil suggests that the attribution of its antimicrobial activity to a particular compound or a synergistic effects between its different constituents remains difficult. Conclusions. The present study demonstrated that Psidium guajava is a valuable source of active compounds with anti- oxidant and antimicrobial activities. This finding suggests the new use of the fruits and the leaves extracts of this plant in the treatment of bacterial and fungal infections, as well as for the extraction of new antioxidants. Therefore, it is necessary to be carried out in another study to identify the active(s) compound(s) in P.guajava essential oil with respect to their mechanisms and synergistic actions.

Opis:
It seems that essential oils can be a good ingredient in effective preparations against Dermanyssus gallinae. Dermanyssus affects animal health leading to financial losses and bird welfare issues. Collected mites were treated with various essential oils in four (20, 50, 80 and 100%) concentrations at a dose of 0.28 mg/cm2. The direct toxicity of the essential oils, mineral oil and spinosad to D. gallinae was tested in the laboratory. Eucalyptus oil was the most toxic essential oil in all concentrations to D. gallinae (87.6 - 97.6% mortality at all four concentrations), while geranium, pine and rosemary oils showed mortality rates of 14.2 - 68.2%. High mortality after 48 hours of contact was also recorded for the oil of cloves at 80% dilution (85.1% mortality), lavender 100% (94.2% mortality). Similarly, the thyme essential oil produced 83.5 - 93.2% mortality in three concentrations: 50, 80 and 100%. The mineral oil was the least effective oil against mites. Spinosad showed high effectiveness against D. gallinae.

Opis:
Civil aviation, similar to other economy sectors, is exposed to cyber-attacks. In this case however, the protection against cybersecurity threats is gaining particular significance, as the industry relies heavily on the use of information systems (information and communication systems with electronic data processed in such systems). The systems are exposed to incidents. Incidents in civil aviation are events occurring in cyberspace which affect, or might potentially affect, the security of aircraft. The issue of cybersecurity in civil aviation is discussed in the context of legal regulations that are in force in Poland and Slovakia. Individual solutions aimed at ensuring the cybersecurity of air transport were analysed.
