Božje milosrđe kao temelj djelatne ljubavi Crkve
Charity diaconia of the Church is not an accidental involvement but belongs to its fundamental missions. This thesis can be supported in many ways. The author of this article finds the source of the obligation of Christians and the whole Church community to charity service in the nature of God. For Christians God is Love (1 John 4, 8.16). Even though some other names can be found, (Jahwe, Elohim, Adonai), his principal name that encapsulates all other ones is Love. Simultaneously, God which is Love showed his merciful nature (misericordiae vultus) in the course of salvation. He did it in a historical, visible and optimal way through his Son, Jesus Christ through the embodied God’s Son, Jesus Christ, who loved the mankind so much that he sacrificed his life for us, being tortured and killed at the cross. This selfless love laid the foundations for the Church, which, in essence, is a community of loving human and God’s beings. Those who do not love, even though they joined the Church through baptism, technically speaking, do not belong to the Church since love is a real not a formal sign of belonging to Christ’s disciples (cf. John 13, 35). Therefore, charitable activity is a significant dimension of the Church’s mission as it is through charity that the Church shows the merciful nature of its Saviour. A question that needs to be addressed may be expressed as follows: in what way the image of God, who is love, implies an involvement in charity of an individual and the Church? An answer may be found in the Bible, writings of the Church Fathers of and the documents of Magisterium Ecclesiae and especially the teachings of Pope Benedict XVI and Pope Francis.Dobrotvorna dijakonija Crkve nije tek slučajna uključenost, već spada u njeno temeljno poslanje. Ova teza može se podržati na više načina. Autor ovoga članka pronalazi izvor obveze kršćana i čitave crkvene zajednice prema dobrotvornom služenju u Božjoj prirodi. Za kršćane Bog je Ljubav (1 Iv 4, 8.16). Iako se mogu naći i neka druga imena (Jahwe, Elohim, Adonai), njegovo glavno ime koje obuhvaća sva druga jest Ljubav. Istodobno, Bog koji je Ljubav pokazao je svoju milosrdno lice (misericordiae vultus) u povijesti spasenja. Učinio je to na povijesni, vidljiv i optimalan način po svome Sinu, Isusu Kristu, utjelovljenom Božjem Sinu, koji je toliko ljubio čovječanstvo da je za nas žrtvovao svoj život, mučen i ubijen na križu. Ta nesebična ljubav postavila je temelje Crkvi koja je u svojoj biti zajednica ljubavi ljudskih i Božjih bića. Oni koji ne ljube, iako su krštenjem pridruženi Crkvi, tehnički gledano, ne pripadaju Crkvi budući da je ljubav stvarni, a ne formalni znak pripadnosti Kristovim učenicima (usp. Iv, 13, 35). Stoga je karitativni rad značajna dimenzija crkvenog poslanja, jer upravo kroz djelotvornu ljubav Crkva pokazuje milosrdno lice svoga Spasitelja. Pitanje na koje je potrebno odgovoriti može se postaviti na sljedeći način: na koji način slika Božja, koji je ljubav, podrazumijeva uključenost pojedinca i Crkve u dobrotvorni rad? Odgovor se može pronaći u Bibliji, u spisima crkvenih otaca i dokumentima Magisterium Ecclesiae, a posebno u učenju pape Benedikta XVI. i pape Franje
Hades experiments : investigation of hadron in-medium properties
Hadron modifications in nuclear matter are discussed in connection to chiral symmetry restoration and/or hadronic many body effects. Experiments with photon, proton and heavy ion beams are used to probe properties of hadrons embedded in nuclear matter at different temperatures and densities. Most of the information was gathered for the light vector mesons , and . HADES is a second generation experiment operating at GSI (Darmstadt) with the main aim to study in-medium modifications by means of dielectron production at the SIS18/Bevelac energy range. Large acceptance and excellent particle identification capabilities allow also for measurements of strangeness production. These abilities combined with the variety of beams provided by the SIS18 lead to a characterization of properties of the dense baryonic matter properties created in heavy ion collisions at these energies. A review of recent experimental results obtained by HADES is presented, with the main emphasis on hadron properties in nuclear matter

Museums of the Mind: My Friendship with Australian Poet, Gwen Harwood
In late winter, 1986, I wrote a letter of appreciation to Australian poet, Gwen Harwood, for her Selected Poems (1975). I mentioned that I was planning to visit Hobart in 1987 and cautiously wondered if we might meet. I enclosed a stamped addressed envelope, hoping, perhaps presumptuously, to receive a reply. After all, it was rumoured she did not like academia and was arguably the finest poet then writing in Australia. She had already won seven prestigious awards and would go on to receive seven more, including three honorary doctorates
Effect of Diet on Mortality and Larval Duration in Chrysodeixis includens (Lepidoptera: Noctuidae)
Diet mediates many life history trade-offs and therefore is an important environmental component to consider. Because some organisms share food sources with humans, they encounter anthropogenic changes to their diet, such as genetically modified crops and chemical applications, which can contribute to additional complexity in their environment. To understand the effect of diet on the life history of the soybean looper, Chrysodeixis includens, we exposed larvae to several different food sources, including genetically modified soybean leaves and the pesticide spinosad. Significant differences in larval instar duration and timing of larval mortality among treatments were observed indicating that type of diet has complex effects on the life history of C. includens
Diaconia as a Challenge for Today’s Christians
Ks. Wiesław PrzygodaThe article focuses on tendencies in the formation in Christian diaconia for
the clergy, religious and laity. The hierarchy members and, indirectly, lay leaders
of Christian associations, are educated to do their leadership tasks in the
spirit of love and service in particular communities. All the followers of Christ,
without any exception, need appropriate formation in Christian lifestyle and
charity.Katolicki Uniwersytet Lubelski Jana Pawła II715316
Wyzwania duszpasterskie wobec osób w podeszłym wieku
The specificity of the senior age is becoming better recognized by gerontology, psychology, sociology and related sciences. It is also a serious challenge for the Church, because this community wants to provide pastoral care for all his faithful adequate to their needs. In this study were firstly presented specific religious needs of the elderly. The objectives and forms of pastoral seniors have also been described. In the final part of this article an apostolic activation of older people was underlined. From the point of view of the people involved it is paramount. The lay Catholics in Poland who are in old age are irreplaceable apostles, especially in the field of building of family bonds, charity, experience of suffering and prayer. The task of the clergy is apostolic formation of seniors, as well as animation of apostolic groups of old people in parishes.Specyfika wieku senioralnego, coraz lepiej rozpoznawana przez gerontologię, psychologię, socjologię i nauki pokrewne, stanowi wyzwanie dla współczesnego Kościoła, który pragnie wszystkie grupy swoich wiernych otaczać adekwatną do ich potrzeb troską duszpasterską. W tym opracowaniu zostaną przedstawione najpierw specyficzne potrzeby religijne ludzi w podeszłym wieku, następnie cele i formy duszpasterstwa seniorów, by w końcowej części skoncentrować się na tym, co z punktu widzenia samych zainteresowanych wydaje się bezcenne, a mianowicie na aktywizacji apostolskiej ludzi starszych. W Polsce świeccy katolicy w podeszłym wieku są niezastąpionymi apostołami, szczególnie w dziedzinie budowania więzi rodzinnych, działalności charytatywnej, zbawczym przeżywaniu cierpienia i modlitwie. Zadaniem duszpasterzy jest natomiast formacja apostolska seniorów, a także animacja apostolskich grup ludzi starych w parafiach
Resonance production and decays in nucleon-nucleon collisions with HADES
The High Acceptance Di-Electron Spectrometer (HADES), installed at GSI, allows to study both hadron and rare dilepton production in a fixed target experiments in the beam energy range of a few GeV per nucleon, reaching up to 4.5 GeV for a proton beam and 1.5 GeV/nucleon for a heavy-ion beam. The present interpretation of dilepton spectra measured in heavy-ion reactions at various energies is based on hadronic models. They predict in-medium modifications of the −meson spectral function due to its coupling to resonance-hole states. In the energy range of the HADES experiments, the −meson can be produced in primary NN or secondary N collisions. The measurement of a dielectron emission in elementary reactions opens the possibility to constrain the interpretation of medium effects and better understand the relation between the couplings of the baryonic resonances to the −meson. The Dalitz decay of baryonic resonances gives access to the electromagnetic structure of baryonic transitions in a timelike region at small positive values of the squared fourmomentum transferred, where couplings to light vector mesons are expected. In this monograph the systematic studies of resonance excitation and decays, measured in NN collisions with the increasing energy, are presented. First, the pp collisions at 1.25 GeV allowed to measure exclusive channels with one-pion in the final state. They were put to extended studies based on various observables in one-pion exchange models and with solutions obtained within the framework of a partial wave analysis (PWA) of the Bonn-Gatchina group. The obtained (1232) production cross section was further used for the first experimental extraction of the Dalitz decay and compared to the models of the electromagnetic transition form factors. The branching ratio of this decay, achieved in the exclusive channel, has been included in the 2018 Review of Particle Physics. In quasi-free np collisions at 1.25 GeV, two-pion production was studied to conclude on double−, N(1440), and (1600) excitation with the aim of studying the production of the −meson in the isospin I = 1 channel. In addition, this analysis provided an independent verification of the existence of the (2370) resonance observed by the WASA Collaboration. Furthermore, a strong excess of the dielectron yield, in comparison to the pp reaction at 1.25 GeV, was observed in the inclusive channel. This reaction is well suited for studies of the np bremsstrahlung with strong isospin effects effects predicted by one-boson-exchange models. The excess was confirmed also in the exclusive channel and the data were compared with the models explaining the enhancement at large invariant masses due to the off-shell −meson production. The exclusive hadronic channels with one-pion and rho−meson were identified in pp collisions at 2.2 GeV. The and eta exclusive production cross sections were extracted and compared to the predictions of a resonance model. Further, the analysis of the exclusive channel allowed for the reconstruction of and Dalitz decays. The angular distributions of in the rest frame were determined to be in agreement with the QED prediction for pseudoscalar mesons. In the pp collisions measured at energy T = 3.5 GeV, a peak corresponding to direct decays, with 2% mass resolution, was reconstructed. The inclusive production cross sections for and mesons were determined from dielectron experimental data for the first time at this energy. In addition, the upper bound for the direct decay was defined. The exclusive one pion production and and dielectron channels were used to extract the and resonance production cross sections. The emission from baryonic decays was identified with the dielectron invariant mass distribution strongly modified by the intermediate rho−meson. This observation has been interpreted within the Vector Dominance Model of the resonance electromagnetic transition form factor. Comparison with various transport models (PYTHIA, GiBUU/SMASH, HSD, UrQMD) unraveled the ambiguities of the model descriptions and the important role of the intermediate rho production. To tackle this problem a systematic investigation focused on the role of N(1520) production and decay in pion-induced reactions was started. Data at four different pion beam momenta (656, 690, 748 and 800 MeV/c) were collected in collisions. In the outlook, exclusive channels with one pion , two pions and dileptons in the final state were discussed, with a special interest for the rhoN channel, since it has a direct impact on the in-medium distortions of the −meson spectral function. Pion beam experiments will be continued in GSI in the next years, then the HADES experimental program will be pursued using the proton and ion beams at FAIR. This monograph has been extended by Appendices covering details on dielectron production channels as well as the models of the electromagnetic transition form factors for baryon resonance Dalitz decays. The HADES spectrometer and the analysis strategy were described, too. The author hopes that this book will serve not only as a report on the scientific achievements but also as a source of information on resonance production and decays in nucleon-nucleon collisions at energies of a few GeV
