The Significance of Effective Labour Inspectoratesfor Cross-border Labour Mobility
Efficiently functioning labour inspectorates play a key role for both fair mobility and the protection of workers’ rights. They contribute, for example, to combating and eliminat-ing hazardous working conditions, and ensuring that remuneration and social insurance premiums are actually paid. This is significant in the context of the posting of workers in the framework of the provision of services. Establishing the liability regarding compli-ance with the occupational health and safety regulations is causing serious practical dif-ficulties. Therefore, it is important above all to identify initiatives undertaken at the EU level designed to enhance cooperation of national labour inspectors in this field. It is also important to carry out an assessment whether they work efficiently, require systematis-ing, or perhaps it is necessary to undertake more formalised initiatives, e.g. in the form of a new EU institution

Radiation Induced Processes in Biomolecules and Clusters in Controlled Beams
The fundamental nanoscale processes that initiate radiation damage in biological material have not yet been fully elucidated. This represents a significant barrier to developing multidimensional simulations of radiation effects that can lead to advances in radiotherapy and radioprotection. This thesis explores UV- and electron-induced processes in DNA and RNA bases. Pure and hydrated clusters are studied in order to better understand the effects of the chemical environment on the radiation response of these important biomolecules.
Although extensive research has been carried out on the relaxation pathways of UV-excited nucleobases, no previous experiments have investigated bond breaking in neutral electronic excited states. This thesis reveals a new fragment ion from uracil (C3H4N2O+) that can be accessed by multi-photon ionization (MPI) but not by electron impact ionization (ElI). This provides the first experimental demonstration that neutral excited state dynamics in a nucleobase can lead to bond breaking in the aromatic ring, as predicted in recent theoretical studies. The specific excited state dynamics have not yet been identified definitively and are the subject of on-going ultrafast pump-probe experiments in collaboration with Townsend and co-workers (Heriot-Watt University). The time-resolved measurements provide new evidence supporting a theoretically predicted relaxation pathway into long-lived triplet states.
Dissociative ionization of hydrated nucleobases and uracil-adenine clusters has been studied experimentally for the first time. Evidence for deamination reactions is observed in hydrated adenine complexes. The production of C3H4N2O+ fragments from uracil is strongly suppressed by clustering with water whereas the channel remains open in uracil-adenine complexes. To unravel the specific cluster-mediated dynamics and reactions responsible for these effects, further experiments are required with greater control over the cluster targets. Indeed the range of monomers and cluster configurations in neutral beams currently limits interpretations and direct comparisons with calculations. In response to this challenge, a new experiment has been built that enables radiation effects to be studied on molecules and clusters in Stark-deflected beams (MPI, ElI, and future electron attachment measurements). Early results on nitromethane beams include a demonstration that studying ElI as a function of the Stark deflector voltage can be used to deduce whether certain product ions came from monomers or from clusters
A new genus, Desertispora, and a new species, Diversispora sabulosa, in the family Diversisporaceae (order Diversisporales, subphylum Glomeromycotina)
Phylogenetic analyses of sequences of the SSU-ITS-LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade at the rank of genus in the family Diversisporaceae of the order Diversisporales. The closest natural relatives of the fungus proved to be species of the genera Corymbiglomus and Redeckera. Consequently, the new genus was named Desertispora, and Di. omaniana was renamed De. omaniana comb. nov. In addition, the morphological and histochemical features of spores and mycorrhizal structures of a new Diversispora sp., Di. sabulosa, were described and the closest relatives of the species were determined based on phylogenetic analyses of sequences of the two loci mentioned above. The new fungus was grown in single-species cultures established from spores extracted from a trap culture inoculated with a mixture of the rhizosphere soil and root fragments of Ammophila arenaria that had colonized maritime sand dunes of the Curonian Spit located in the north of Lithuania. Diversispora sabulosa was never found before in many different sites of the world which were sampled during the last 34 years by the last author of the paper. Also, the lack of molecular sequences in public databases of identity ≥ 97% to sequences of Di. sabulosa suggests that the fungus is rare on the Earth
The therapeutic potential of truffle fungi: a patent survey
The purpose of this article is to research and retrieve patent information regarding
the therapeutic use of truffles. Truffles have a unique value as a foodstuff and impact
positively on human health and well-being. They are applied in such industries as the
pharmaceutical industry and the cosmetic industry. Patent documentation available in
the Espacenet network and the Patentscope service were analyzed by key word and patent
specifications were examined to describe state of the art and to identify scientific research
trends in therapeutic applications of truffles. Medicinal properties of truffles such as the
anticancer or cardiovascular effect, a reduction in blood lipids, immunological resistance
and increased energy were identified. Other therapeutic benefits include sedative action,
prevention of hormonal imbalances in women, pre-menopause symptom relief, senile
urethritis and prostate disorders, sleep disorders and increased absorption of calcium
from milk. Truffles can also be used to alleviate symptoms of milk intolerance such as
diarrhoea or bloating, to ease rheumatic pains and to treat and prevent further development
or recurrence of senile cataract
Idea licznych beatyfikacji i kanonizacji w pedagogii Jana Pawła II
From the very beginning the Church has been caring for the vocation to sanctity which is perceived as the core of Christian life. Teaching sanctity may have different forms. One of the most essential of them is presenting the example of one’s life. The figures of saints and blesseds are of great help during the process of becoming a mature person. They had a crucial educational function in John Paul II’s teaching as they encouraged to follow the ideal of sanctity. Therefore, the concept of numerous beatifications and canonizations in Pope’s teaching has pedagogical significance. Implementing the rules of the pedagogy of sanctity is the mission of the Church which should be recalled in the context of John Paul II’s canonization.Kościół od początku pielęgnował powołanie do świętości jako pełni życia chrześcijańskiego. Wychowanie do świętości może być realizowane na różne sposoby, wśród których osobisty przykład odgrywa wyjątkową rolę. Postacie świętych i błogosławionych są cenną pomocą w dojrzewaniu do pełni rozwoju człowieka. W nauczaniu Jana Pawła II pełnili oni bardzo ważną funkcje wychowawczą: przybliżali ideał świętości i stanowili zachętę do jego realizacji. Idea licznych beatyfikacji i kanonizacji realizowana przez świętego papieża ma więc znaczenie pedagogiczne. Realizacja zasad pedagogiki świętości jest zadaniem dla Kościoła, które warto przypomnieć w kontekście kanonizacji Jana Pawła II
Dissociative multi-photon ionization of isolated uracil and uracil-adenine complexes
Recent multi-photon ionization (MPI) experiments on uracil revealed a fragment ion at m/z 84 that was proposed as a potential marker for ring opening in the electronically excited neutral molecule. The present MPI measurements on deuterated uracil identify the fragment as C3H4N2O+ (uracil+ less CO), a plausible dissociative ionization product from the theoretically predicted open-ring isomer. Equivalent measurements on thymine do not reveal an analogous CO loss channel, suggesting greater stability of the excited DNA base. MPI and electron impact ionization experiments have been carried out on uracil-adenine clusters in order to better understand the radiation response of uracil within RNA. Evidence for C3H4N2O+ production from multi-photon-ionized uracil-adenine clusters is tentatively attributed to a significant population of π-stacked configurations in the neutral beam
