The thesis includes the results of over ten years' research and observations of the population process of epilithic lichens on the newly exposed surfaces of erratic boulders. The research was carried out in the 'Kręgi Kamienne' Archaeological and Nature Reserve located in the Tucholskie Forest (N Poland). The thesis presents the seąuence of population and the quantitative changes of pioneering lichens. The following phases of initial stage of succession, which have lasted for at least 30 years, were distinguished and characterized: the phase of pulverulent lichens, the beginning phase of <em>Lecidea fuscoatra</em> domination and the phase of boulders population by <em>Porpidia</em> and <em>Rhizocarpon</em> genera species. The optimal stage was specified on the basis of initial population of foliose lichens and formation of epilithic lichen associations.

The thesis includes the results of over ten years' research and observations of lichens on the straw-thatched roofs. The research sites were the villages located inside and on the edge of the vast lowland forests in Poland. The thatched roofs made of straw, which has been laid out for 1–50 years, were examined. Duration of the population process and quantitative changes of pioneering lichens were analysed. The following phases of the initial stage of formation of lichen flora were distinguished and characterized: the phase of occurrence of crustose lichens ('the straw thatch'), the phase of expansion of cup-moss ('the cup-moss thatch') and the phase of a shared domination of lichens and mosses ('the grey-green thatch'). The morphological and ecological features of pioneering lichens were revealed.

The fir (Abies gracilis) grove (Kamchatka Peninsula, Kronotsky State Nature Reserve) is a unique area for the northern part of the Russian Far East. As a result of revision of herbarium specimens and literature data a list of lichens of the fir grove was compiled, comprising 55 species. Of them, 27 species are new to the Kronotsky Reserve, 30 are firstly reported for the grove. Altogether 36 lichen epiphytes of Abies gracilis are known.

The results of field studies of the lichen flora of the Kerzhensky Reserve (Nizhny Novgorod Region), carried out mainly in the Kerzhenets River valley in May 2019, are presented. An annotated list of taxa previously unknown for the reserve includes 121 species from 70 genera. Of these, 97 species and 31 genera are new to the Nizhny Novgorod Region. The species Micarea soralifera and Rinodina excrescens are published for the first time for European Russia. We have found some very rare species in European Russia previously known from single records (Agonimia repleta, Bacidina indigens, Gyalideopsis alnicola, Sclerophora amabilis, Stigmidium mycobilimbiae, Telogalla olivieri, and Verrucaria ochrostoma).

Matakuliah proyek perangkat lunak digunakan untuk melatih mahasiswa dalam penguasaan materi pengembangan perangkat lunak yang terdiri dari analisis, desain, implementasi, dan evaluasi. Mahasiswa diajarkan bagaimana cara mengerjakan perangkat lunak dari tahap awal hingga tahap akhir. Selain itu, mahasiswa juga dilatih untuk bekerja secara tim. Permasalahan yang terdapat pada Universitas Dian Nuswantoro adalah pembentukan kelompok masih dilakukan secara random-select. Pembentukan kelompok yang dilakukan mahasiswa berdasarkan unsur pertemanan, satu komunitas, atau grup di social media seperti WhatsApp. Hasilnya, terjadi ketidakseimbangan di dalam kelompok tim proyek. Ketidakseimbangan tim proyek dapat menyebabkan gagalnya proyek pengembangan perangkat lunak. Penelitian ini mengusulkan eksperimen pendekatan dynamic group formation dengan algoritma genetika. Hasil dari eksperimen menunjukkan bahwa algoritma genetika mampu membantu pembentukan kelompok tim proyek dengan tingkat keberhasilan 87.5% dengan pengaturan inisial populasi adalah 100 populasi dan probabilitas crossover adalah 0.6. Tujuan dari penelitian ini adalah memberikan alternatif pembentukan kelompok mahasiswa secara dinamis guna mendukung kolaborasi tim proyek mahasiswa. Pada proyek perangkat lunak kedepan, tidak ada pembentukan tim proyek secara homogen atau pemilihan anggota tim proyek secara self-select atau random-select. AbstractSoftware project courses are used to train students in mastering software development materials consisting of analysis, design, implementation, and evaluation. Students are taught how to work on software from the initial stage to the final stage. In addition, students are also trained to work in teams. The problem in Universitas Dian Nuswantoro is that group formation is still done randomly-selectively. The formation of groups by students is based on the friendship level, a community, or a group on social media such as WhatsApp. As a result, there is an imbalance in the project team. Imbalance of the project team can cause the failure of software development projects. This study proposes an experiment using a dynamic group formation approach with genetic algorithms. The results of the experiment show that the genetic algorithm is able to help the formation of project team groups with a success rate of 87.5% with the initial population is 100 population and the probability of crossover (pc) is 0.6. The objective of this study is to provide an alternative dynamic formation of student groups to support the collaboration of student project teams. In the future, there is no homogeneous project team formation or selection of member teams using a self-select or random-select method.

New data on the lichen flora of the Kologriv Forest Nature Reserve from the cluster Kologrivskiy are provided. The specimens of lichens, lichenicolous fungi and non-lichenized saprophytic fungi were collected from 9 localities mainly in the Sekha River valley in cluster Kologrivskiy in September 2018. Altogether 110 lichen species, 9 non-lichenized saprobic fungi and 2 lichenicolous fungi are recorded for the first time for the nature reserve, including 69 species and 21 genera new for the Kostroma Region. The genus Leptosillia with species L. wienkampii and lichenicolous fungus Opegrapha phaeophysciae are published for the first time for European Russia. Altogether over 20 indicator species and habitat specialists of biologically valuable forests are known from the study area. Moreover 4 species (Leptogium burnetiae, Lobaria pulmonaria, Menegazzia terebrata, Nephromopsis laureri) are included in the Red Data Book of Russia.

78 lichen species, the list of which was given, were found on 42 erratic blocks. There arę a few very rare and becoming extinct on the Polish lowland taxa among them, e.g. <em>Aspicilia gibbosa</em> (Ach.) Koerber, <em>Bacidina inundata</em> (Fr.) Yezda, <em>Micarea syhicola</em> (Flotow) Yezda et V. Wirth, <em>Porina chlorotica</em> (Ach.) Miill. Arg., <em>Rluzocarpon lecanorinum</em> Anders and <em>Xanthoparmelia angustiphylla</em> (Gyelnik) Hale. A tendency to decrease the epilithic flora of erratic blocks was stated. Natural and anthropogenic factors that arę dangerous to epilithic lichens were described. Monitoring of the most valuable boulders is necessary, including frequent and periodical evaluation of the conditions of a given habitat. The protection must include smaller boulders, stones and groups of them.

Lower Reflectance

Light microscopy was used to analyze the effects of added catalyst at different conditions (temperature and reaction times) in liquefaction testing of a low pyritic sulfur bituminous coal. Quantitative changes in vitrinite/vitroplast reflectance of coal and liquefaction residues were shown to be useful markers in analyzing and understanding the role of catalyst during the initial stage of coal particle hydrogenation. Lower reflectance values corresponded to increased conversions up to about the 60 min and 375°C experimental conditions. Microscopical observation of liquefaction residues also revealed the presence of “wall scales” of varying width.
