Wczesnośredniowieczne grodzisko w Dusinie, pow. gostyński, woj. wielkopolskie w świetle ponownej analizy archeologicznej

The article presents the results of another archaeological analysis carried out on materials from an early medieval settlement in Dusina in southern Greater Poland. The data obtained during the excavations, during the millennium research, prompted the recognition of the settlement as the oldest motte-type object in Poland. During the verification of the old findings, the ceramic material and the stratigraphic situation were re-analyzed, radiocarbon dating was made, and historical and cartographic data were used to confirm the chronology of the stronghold as well as the course of events that led to severe damage and disturbance of the original appearance of the stronghold. A contour plan and a model of the terrain were also prepared.

Deeply Buried Nuclei in the Infrared-luminous Galaxies NGC 4418 and Arp 220. II. Line Forests at λ = 1.4–0.4 mm and Circumnuclear Gas Observed with ALMA

We present the line observations in our Atacama Millimeter-Submillimeter Array imaging spectral scan toward three deeply buried nuclei in NGC 4418 and Arp 220. We cover 67 GHz in f rest = 215–697 GHz at about 0.″2 (30, 80 pc) resolution. All the nuclei show dense line forests; we report our initial line identification using 55 species. The line velocities generally indicate gas rotation around each nucleus, tracing nuclear disks of ∼100 pc in size. We confirmed the counter-rotation of the nuclear disks in Arp 220 and that of the nuclear disk and the galactic disk in NGC 4418. While the brightest lines exceed 100 K, most of the major lines and many 13C isotopologues show absorption against even brighter continuum cores of the nuclei. The lines with higher upper-level energies, including those from vibrationally excited molecules, tend to arise from smaller areas, indicating radially varying conditions in these nuclei. The outflows from the two Arp 220 nuclei cause blueshifted line absorption below the continuum level. The absorption mostly has small spatial offsets from the continuum peaks to indicate the outflow orientations. The bipolar outflow from the western nucleus is also imaged in multiple emission lines, showing the extent of ∼1″ (400 pc). Redshifted line absorption against the nucleus of NGC 4418 indicates either an inward gas motion or a small collimated outflow slanted to the nuclear disk. We also resolved some previous confusions due to line blending and misidentification.

Gemini/GMOS Transmission Spectroscopy of the Grazing Planet Candidate WD 1856+534 b

WD 1856+534 b is a Jupiter-sized, cool giant planet candidate transiting the white dwarf WD 1856+534. Here, we report an optical transmission spectrum of WD 1856+534 b obtained from ten transits using the Gemini Multi-Object Spectrograph. This system is challenging to observe due to the faintness of the host star and the short transit duration. Nevertheless, our phase-folded white light curve reached a precision of 0.12%. WD 1856+534 b provides a unique transit configuration compared to other known exoplanets: the planet is 8× larger than its star and occults over half of the stellar disk during mid-transit. Consequently, many standard modeling assumptions do not hold. We introduce the concept of a “limb darkening corrected, time-averaged transmission spectrum” and propose that this is more suitable than ( R p , λ / R s ) 2 for comparisons to atmospheric models for planets with grazing transits. We also present a modified radiative transfer prescription. Though the transmission spectrum shows no prominent absorption features, it is sufficiently precise to constrain the mass of WD 1856+534 b to be >0.84 M J (to 2σ confidence), assuming a clear atmosphere and a Jovian composition. High-altitude cloud decks can allow lower masses. WD 1856+534 b could have formed either as a result of common envelope evolution or migration under the Kozai–Lidov mechanism. Further studies of WD 1856+534 b, alongside new dedicated searches for substellar objects around white dwarfs, will shed further light on the mysteries of post-main-sequence planetary systems.

Abject Object Relations and Epistemic Engagement in Clinical Practice

The article engages with medical practice to develop a philosophically informed understanding of epistemic engagement in medicine, and epistemic object relations more broadly. I take point of departure in the clinal encounter and draw on French psychoanalytical theory to develop and expand a taxonomy already proposed by Karin Knorr-Cetina. Doing so, I argue for the addition of an abject type object relation, that is, the encounter with objects that transgress frameworks and disrupt further investigation, hence preventing dynamic engagement and negatively shaping our epistemic pathways. The article is primarily theoretical although partly grounded in qualitative fieldwork.

System research of priority geological objects in the Pripyat trough with the intent of increasing the hydrocarbon resource potential

A new direction of system research in the Pripyat Trough to increase the hydrocarbon resource potential of the bowels on the basis of modern geological and geophysical technologies has been justified. Two-type priority objects, which are oil and gas prospecting and research polygons, are distinguished. The first-type object is represented by large oil multifield and prohibitive structures in the highly promising areas and sections. The second-type object includes the structures of the western part of the Central Zone of the Pripyat Trough where a rather high level of direct oil and gas occurrences is established.

Dust Science with the DESTINY+ Dust Analyzer

<p>The DESTINY+<br />spacecraft (Demonstration and Experiment of Space Technology for<br />INterplanetary voYage with Phaethon fLyby and dUst Science) will be launched to the<br />active asteroid (3200) Phaethon by the Japanese Space Agency JAXA in 2024. The main<br />mission target will be Phaethon with a close flyby in 2028. Together with two cameras, the<br />DESTINY+ Dust Analyzer (DDA) on board will perform close observations of this rockcomet type object to solve essential questions related to the evolution of our inner Solar<br />System, especially the heating processes of small bodies. Phaethon is believed to be the<br />parent body of the Geminids meteor shower and is considered to be a comet-asteroid<br />transition object. Such objects likely play a major role to better understand the nature and<br />origin of mass accreted on to Earth. The DDA dust analyzer is an upgrade of the Cassini<br />Cosmic Dust Analyzer (CDA) which very successfully investigated the dust environment of<br />the Saturnian system. The DDA instrument is an impact ionization time-of-flight mass<br />spectrometer with integrated trajectory sensor, which will analyse sub-micrometer and<br />micrometer sized dust particles. The instrument will measure the particle composition (mass<br />resolution m/Δm ≈ 100-150), mass, electrical charge, impact velocity (about 10% accuracy),<br />and impact direction (about 10° accuracy). In addition to dust analysis in the vicinity of<br />Phaethon during the close flyby at this small asteroid, DDA will continuously measure dust<br />in interplanetary space in the spatial region between 0.9 and 1.1 AU during the<br />approximately four years spanning cruise phase from Earth to Phaethon. We give a progress<br />report of the instrument development together with an update on the preparation of the<br />scientific measurements planned during the DESTINY+ mission.</p>

REGULARITIES OF NOMINATION OF SUBSTANTIVE NAMES OF THE CONSTRUCTION SPHERE IN THE MODERN BELARUSIAN LANGUAGE

Onomasiology occupies one of the important places among the sciences that study the lexical and semantic level of language, as it studies both the problems of formation of language nominations and the nominations themselves – the result of these processes. The process of naming, which is the subject of nomination theory, is a complex thought and speech process, which distinguishes several stages: the stage of isolation by consciousness of the object to be named, comprehension of the denoted and the choice of adequate linguistic means of naming. In this regard, of particular interest are derived names in which it is possible to establish onomasiological structure. Onomasiological analysis of nominative units allows to record the features of nominative human activity. Observations show that such an analysis is applicable to derivatives of universes (monosyllabic names), which are formed in different ways, biverbal and polyverbal names. An important issue in modern onomasiology is the study of the types of nominations that are formed on the basis of motivated features, and their relationship with the methods of nomination. The study aims to identify the features of these relationships within the considered thematic subgroups. Taking into account the developed typologies in this work, an attempt is made to consider the onomasiological structure of the names of the construction industry and to isolate the types according to the nature of the onomasiological feature. It is possible to distinguish onomasiological feature for each derived name by reproducing the nominative judgment. Аmong the noun building terminological units, nominations belonging to the promotional type, object type, locative type and qualifying type were singled out. In addition, in the action type there are action-object and adjective-action subtypes. Types and subtypes are considered in connection with nomination methods where derivational means play an important role. The account of affixes allows to correlate language units with character of an onomasiological sign and to establish, what on value of group of subject names have arisen by means of this or that sign and what derivational means are used as bases at these signs.

Implementation of the logistics train in the intralogistics system: A case study

Intralogistics contributes significantly to the proper functioning of business processes. When designing and solving intralogistics systems, it is necessary to take into account the specific conditions in the given enterprise. The technical design, as well as the composition of the trolleys in the design of the transport system, must respect the specificities of the goods transported as well as shelf life and quantity. The study presents, for example, the implementation of a tugger train into an intercompany system with a solution procedure that is adapted to specific operating conditions and ensures the smooth functioning of the supply process. It is a principle based on the use of a simulation model. During its creation, three original sequences were developed in the programming language SimTalk. Their application decreases the use of blocks from the simulation program by up to 65% and it was possible to model more detailed processes that would not be possible in terms of functionality by using classical blocks. Fifteen directions of the language SimTalk were applied in their creation. Two variables of the type Integer, two variables of the type Object, and one variable of the type Real were defined.
