The ultrastructure of reproductive organs of pine, spruce, larch and ginkgo was investigated. It was found that the male reproductive organs possess similar organization. The most considerable change in the ultrastructure of the microsporocytes occur in meiosis. Sporoderm is being laid at the late tetrad stage. The cells of the male gameto-phyte are distinguished according to the metabolic activity of the or- ganells. They are most weakly developed in the spermiogenic cell. Ta-petum of the gymnosperms is of the periplasmodic - secretorial type. The Ubisch bodies which possess similar structure in the types investigated but are specific in details in different species are produced in tapetum.Parietal and subepidermal layers are distinguished for their high metabolic activity and are capable of the autonomous photosynthesis. Female reproductive organs differ more greatly in their struture and have the most complicated structure in primitive groups. On the first stages of their formation the inner cells of nucellus are transformed into the nucellar tapetum in which the structures similar to the Ubisch bodies taking part in the formation of the sporoderm of female gametophyte have been found.

A hybrid model for the time series of complex structure (HMTS) was proposed. It is based on the combination of function expansions in a wavelet series with ARIMA models. HMTS has regular and anomalous components. The time series components, obtained after expansion, have a simpler structure that makes it possible to identify the ARIMA model if the components are stationary. This allows us to obtain a more accurate ARIMA model for a time series of complicated structure and to extend the area for application. To identify the HMTS anomalous component, threshold functions are applied. This paper describes a technique to identify HMTS and proposes operations to detect anomalies. With the example of an ionospheric parameter time series, we show the HMTS efficiency, describe the results and their application in detecting ionospheric anomalies. The HMTS was compared with the nonlinear autoregression neural network NARX, which confirmed HMTS efficiency.

Preliminary Study

Survey on invertebrate biodiversity of volcanic caves in Krong No, Dak Nong province, Vietnam was carried in 2018 and 2019. The survey were done in 8 typical caves are Co cave (475 m long), C1 cave (402 m), C2 cave (402 m), C3 cave (716 m), C4 cave (251 m), C6 cave (180 m), C6.1 cave (293 m) and C7 cave (1066 m). The survey result recorded 41 species, 31 families of 5 classes, 13 orders of invertebrate at volcanic caves in Krong No. It is expected that 13 species will become new taxa, for example a scorpion of the Chaerilidae family, Chaerilus chubluk Lourenco, Tran & Pham, 2020 in the Co cave. The large and long caves with a complicated structure with many corners are more valuable in term of biological diversity than the small caves with a simple structure.

Abstract This paper deals with the ways of categorising landscapes as ‘urban’ and ‘rural’ using a physicalist approach, where these terms have special meaning. The aim of this paper is to elaborate on the question whether such a division is still meaningful with regard to anthropogenic landscapes, not least in spatial planning. The concerns raised in this paper depart from the increasingly complicated structure of geographical space, including that of anthropogenic landscapes. Our standpoint is illustrated using cases of landscape ambiguities from Poland, Germany, Romania and Greece. Leaning on frameworks of physicalist (mechanicistic) theory, this paper suggests an explanation to the outlined semantic conflicts. This is done by pointing to the relationality between the impact of centripetal and centrifugal forces, the specifics of socio-economic development, as well as the varying landscape forms that emerge from the differences within that development.

The article for the first time analyses the decoration parts of the Christ’s tomb of the second halfof the 18th century found a few years ago in Švėkšna church. The Christ’s tomb from the oldchurch was transferred to the  new church, which was built in 1804 and used until the  4thdecade of the 19th century. On the basis of the sources and remained fragments we can statethat this was a complicated structure of the Paschal decoration designed under the Europeanbaroque scenery principles. It was composed of the paintings on boards and canvas and mis-cellaneous accessories. The  Christ’s tomb paintings are characterised by a  symbolic allegoriccontent and artistry. The prophets of the Old Testament and characters the New Testamentreflecting the Paschal Triduum liturgy were depicted in the decoration. The survived outlinepaintings of Adam and Eve in Paradise, Noah waiting for the Saviour, and Angels Lamentingover the Death of Jesus are the exceptional iconography images in the Lithuanian church art.The decorations of the Christ’s tomb were created by the professional masters who decoratedthe churches in Samogitia in the second part of the 18th century. The images of suffering anddead Jesus used in the figuration of the Paschal Triduum influenced the spread of the Passionscenes. This is supported by an interesting archival fact about the shrine with a group of sculp-tures depicting the tomb of Christ in the Švėkšna churchyard.The fragments of the Paschal decorations in the Švėkšna church are important baroque scen-ery exhibits, which are valuable for the history of the Lithuanian church art and scenography.The investigation of the Holy Week figuration in the Švėkšna church is a valuable illustrationof this multidimensional cultural, religious and artistic phenomenon.

With mining technology and mechanization degree being improving, fully mechanized caving mining technology (FCM) has become a main method for thick coal seam extraction in China. However, roof-coal caving characteristics in turn restrict its recovery efficiency, especially for the coal seam with complicated structure (CCS), that is, the coal seam comprises hard or soft coal and gangue. In order to explore the key factors influencing the roof-coal caving and recovery characteristics, related research work has been conducted as follows: firstly, a mechanical model of CCS has been established, which indicates the strength of the coal and gangue will directly affect the roof-coal recovery. Meanwhile, based on the geological settings of Qinyuan coal mine, numerical simulation on roof-coal caving law under different thicknesses of hard or soft coal and gangue has been performed using UDEC software. The results show that the maximum principal stress will increase with the increase of mining depth, making the roof-coal to break easily. Furthermore, the range of the plastic zone of the top coal and the damage degree of the top coal increase with the increase of mining depth. Physical modeling results show that when an extraction-caving ratio is 1, the number of times the coal arch forms is 0.43 at every caving, up to a maximum of 3; the number of times coal arch forms with an extraction-caving ratio of 2 is 4.65 times larger than that with an extraction-caving ratio of 1. The probability of coal arch formation with an extraction-caving ratio of 3 is minimal, about 0.4, which is due to that the arch span is large and the curvature is small, so it is difficult to form a stable arch structure. According to the mechanical characteristics of roof-coal in Qinyuan coal mine, deep-hole blasting technique has been used to reduce the fragments of roof-coal crushed. The results show that this technique can effectively improve the recovery of roof-coal.

This chapter discusses the remedies that can be sought from the civil courts and how an appeal is made against a decision. It covers interim and final remedies; route of appeals; leave; the hearing; appeals to the Supreme Court; and examples of appeals. There are many different types of remedies that a court can award to a successful litigant. The most common form of remedy is that which is known as ‘damages’. Appeals in the civil courts follow a slightly more complicated structure than in criminal cases. In order to appeal in the civil cases it is usually necessary to seek permission before proceeding with a civil appeal. Save where it is a final decision in a multi-track case, the usual rule is that the appeal will be heard by the next most senior judge.

Parabolic Fixed Point

We use dynamical approach to study parabolic fixed points of Kleinian groups Γ ⊂ Iso (ℍn). Let ℋ be the horospherical foliation on the unit tangent bundle SM of manifold M = Γ\ℍn with constant negative curvature. We construct examples Γ ⊂ Iso (ℍ4) which show that horosphere based at parabolic fixed point w ∈ ∂ℍ4 can project to leaf ℋx ⊂ SM of complicated structure: it can be locally closed and not closed; not locally closed and non-dense in the non-wandering set Ω+ ⊂ SM of ℋ; dense in Ω+ (this is equivalent to w being a horospherical limit point). Using the natural duality, one gets the corresponding examples of Γ-orbits on the light cone. We give an elementary proof of the fact that conical limit point w ∈ ∂ℍn cannot be a parabolic fixed point.
