Abstract
We continue our study, started in [A. Češík, G. Gravina and M. Kampschulte,
Inertial evolution of non-linear viscoelastic solids in the face of (self-)collision,
Calc. Var. Partial Differential Equations 63 2024, 2, Paper No. 55], of (self-)collisions of viscoelastic solids in an inertial regime. We show existence of weak solutions with a corresponding contact force measure in the case of solids with only Lipschitz-regular boundaries. This necessitates a careful study of different concepts of tangent and normal cones and the role these play both in the proofs and in the formulation of the problem itself. Consistent with our previous approach, we study contact without resorting to penalization, i.e., by only relying on a strict non-interpenetration condition. Additionally, we improve the strategies of our previous proof, eliminating the need for regularization terms across all levels of approximation.
More Than One Encounter: Exploring the Second-Person Perspective and the In-Between
Authors: Hansen Bjarke Mørkøre Stigel 
Published: November 2024

Abstract
In this essay, I explore the notion of the encounter as a challenge to the second-person perspective. I do so by turning to Jacques Derrida’s account of the encounter with the associated notions of address, second-person perspective, otherness, and the secret involved in the understanding of the encounter. My argument is not only that such a dynamic can be seen in Derrida’s deliberation, but also that drawing the connection between encounter and Derrida’s account highlights the complex way in which the second-person perspective is involved in the dialogical situation.

Authors: Alvarado-Solano Anddy 
Published: November 2024

Abstract
In this work we present an easy and direct construction of a Stochastic integral respect a cylindrical martingale-Lévy process. To do this, we apply the radonification technique. The radonification technique has been very useful to define an genuine stochastic process starting from a cylindrical process combine with Hilbert–Schmidt operators. With this work we present a self-contained construction, easy to follow to understand this new integration theories that are getting strong nowadays.

Published: November 2024

Abstract
Angesichts eines dynamischen industriellen Umfelds müssen produzierende Unternehmen flexibel bleiben und sich kontinuierlich anpassen, um ihre Wettbewerbsfähigkeit zu erhalten. Eine effektive Planung von Restrukturierungen in Produktionssystemen, oft als Umzugsplanung bezeichnet, ist entscheidend, um Verzögerungen zu vermeiden und Stillstandszeiten zu minimieren. Die Identifikation von Umzugsfällen, welche den Umfang umzuziehender Ressourcen wie Maschinen, Anlagen, Ausrüstungen und Arbeitsplätzen beschreiben und die Definition zugehöriger Aufgaben sind essenzielle Schritte der Umzugsplanung. Dieser Beitrag stellt eine Vorgehensweise zur Bestimmung von Umzugsfällen mittels eines Fabrikdatenmodells vor, ergänzt durch eine Visualisierung in Virtual Reality, um Planende bei der Umzugsplanung zu unterstützen.
Zielführendes Verhalten auf dem Shopfloor
Authors: Mechenbier Sarah , Metternich Joachim 
Published: November 2024

Abstract
Unternehmen müssen sich verändernde Ziele verfolgen, um konkurrenzfähig zu bleiben. Zum Erfolg sind sie u.a. auf das zielführende Verhalten von Mitarbeitenden angewiesen. Klassische Produktionsmanagementansätze stützen sich auf logikbasierten Methodiken. Das Verhalten von Mitarbeitenden wird davon häufig nicht nachhaltig beeinflusst, da Menschen vor allem unter Zeitdruck intuitiv handeln und logische Fakten vernachlässigen. Zur systematischen Unterstützung des intuitiven Handels bietet Nudging beachtliches Potenzial.
Pre-r/l breaking in English and the diphthongal bias
Authors: Starčević Attila 
Published: November 2024

AbstractWe analyse j/w+r sequences in the history Early Modern English (EMoE), the predecessor of Standard (Reference) British English (SSBE) and its most current version, Current British English (CUBE) to arrive at the nature of historical pre-r (and also pre-l) breaking, a process (together with r-deletion and smoothing) responsible for the phonemic contrast between schwa-final and any other diphthongs (and long vowels): bear ɛə vs bay ej (or eɪ), lore ɔə vs law ɔː vs low ow at the beginning of the twentieth century, found as bɛː vs bɛj, loː law/lore vs ləw low CUBE. The main thrust of the argument presented here is that (i) (historical) diphthongs and the long high monophthongs are uniformly represented as vowel+glide sequences, giving ‘bias’ to the title and (ii) that breaking is consonant prevocalisation (CP) of r/ɫ in j/w+r/ɫ sequences (lejr > lejər lair, fajɫ > fajəɫ file). This is followed by r-deletion and smoothing (leər > lɛə > lɛː lair), which are unrelated to breaking ‘proper’. The analysis of breaking as consonant prevocalisation builds on the framework developed by Operstein (2010), with earlier precursors in articulatory phonology, historical linguistics (e.g. Howell 1991a, 1991b), and frameworks using privative melodic features, such as government phonology (e.g. Kaye, Lowenstamm & Vergnaud 1985), dependency phonology (Anderson & Ewen 1987), particle phonology (Schane 1984), element theory (Backley 2011), etc. The article introduces the theoretical background in section 1, followed in section 2 by a discussion of breaking in the history of English. We then look at a classical interpretation of breaking and discuss its shortcomings in section 3. We then look at why the long high monophthongs are better analysed as diphthongs in section 4 before we look at how these vowels fit into the bigger canvas of the diphthongs in section 5. The next step in sections 6 and 7 takes us to the analysis of breaking as CP happening in jr, wr and jɫ sequences. In section 8 we look at CP undone in the later history of the language and some of the consequences for earlier English that follow from the modern distribution of j/w+r sequences.
Localization of hidden leaks in water supply networks by hydraulic methods
Authors: Bodnar Taras , Makovskyi Yevhenii , Zhuk Volodymyr 
Published: November 2024

AbstractThe hydraulic gradient method is an effective approach for localizing hidden leaks in water supply networks. Relative errors in leakage location depend significantly on head measurement errors, necessitating the use of high-precision pressure gauges with an accuracy class of 0.25 or better. An optimization function, defined as the ratio of the localization relative error to the probability of detection, was used to determine the optimal location for the control section. Dependencies of localization relative error on the pressure gauge accuracy class, section length, and piezometric head are obtained. Presented multi-leakage estimation model enables the assessment of the multi-leakage probability, enhancing decision-making efficiency for emergency repairs in water supply networks.
Radioactivity of some Rock Types of Andhra State, India
Authors: Mahadevan C. , Tilak V. V. S. S. , Aswathanarayana U. 
Published: November 2024

Abstract
Beta-activity has been determined for 37 rocks (12 gneisses, 7 granites, 7 charnockites. 5 calc-granulites and 6 schists) drawn from various parts of Andhra Pradesh. For 15 samples selected from the above groups, alpha-activity was also determined, for effecting a comparative study of the two sets of measurements. The present work confirms the results of previous studies which showed that the beta-activity of a rock is conditioned by the following mutually-related factors: chemical composition (Fe2O3: FeO ratio, silica, potash, alumina, and calcium oxide concentrations), mineralogical composition (quartz, feldspar and heavy mineral contents), and petrogenetic history. The discrepancies in the equivalent uranium content of rocks as deduced from their beta- and alpha-activities, are traced to the variations in the concentration of beta-emitting K40 and U : Th ratios.
Nickel Ore in Tagaung Taung, Upper Burma
Authors: Ferencic Ante 
Published: November 2024

Abstract
The occurrences of nickel silicates in the north-western part of the mountain mass Tagaung Taung in Upper Burma, were the object of geologic investigations in April 1957 by geologists of "Geoistrazivanja" Zagreb, Yugoslavia.
The explored area consists of ultrabasic (ultramafic) rocks (dunite, saxonite, lherzolite, wehrlite) which are partly serpentinized and in general strongly weathered. Many garnierite veins and boxwork within the zones of brecciated serpentinite with opal-quartz cement, occur in the north-western Tagaung Taung region. At 4 localities mineralization of garnierite reached a comparatively higher degree. The garnierite deposit in Innet Taung, locality A, was particularly studied and the quality and quantity of ore evaluated.
There are also outcrops of chromite and chromite-bearing placer accumulations, as well as occurrences of some other minerals (copper and manganese ores and magnesite), but these have not received close attention in this article.
Garnierite, as nickel ore, is of economic significance. The chromite outcrops, chromite placer deposits and other ore occurrences should be explored further, since the present data are not sufficient for an economic estimate of the occurrences.
Some Observations on the Structure, Metamorphism, and Geological Evolution of Peninsular India
Authors: Pichamuthu C. S. 
Published: November 2024

Abstract
Peninsular India, like other shield areas of the world, displays an ingrained pattern of successive orogenic belts. The description of these belts is accompanied by a tectonic map in which are noted the main structural trends as well as many of the reliable ages so far determined.
The variations in the grades of metamorphism which can be recognised in South India are delineated in a sketch map. There is a general progressive increase in the intensity of metamorphism from north-west to south-east. The highest grades are met within the southern and south-eastern parts of the Peninsula where charnockites and khondalites are prevalent.
The successive stages in the geological evolution of Peninsular India are next described. The structural pattern as well as relative ages indicate that the oldest rocks are found in the type area for Dharwar Schists in Mysore State. This region is a continental nucleus, and the Eastern Ghats and Satpura provinces are later Precambrian accretions which have been folded by pressures directed towards this Archaean nucleus.
Fossil Primates from the Siwalik Beds near Haritalyangar, Himachal Pradesh, India
Authors: Prasad K. N. 
Published: November 2024

Abstract
Certain Primate fossils collected by the author from the Nagri beds at Haritalyangar are described in this paper. A left mandibular ramus with the associated dentition is assigned to a new species of Sivapithecus on the basis of certain specific characters. The great vertical depth of the jaw combined with a short symphysis is rather suggestive of a new species. The mandible has also been compared with other known Dryopithecinae from the Siwaliks of India as well as those from Africa, particularly with Proconsul major, a large ape from the Miocene of Kenya.
The other moiety described includes a fragment of a mandible with two excellently preserved molars. Apart from their large size, the two molars do not show any significant differences from Sivapithecus indicus. It was undoubtedly a large ape next only in size to Dryopithecus giganteus. An isolated, narrow lower molar with high crowns recognised in the collection is referred to the genus Sugrivapithecus. Another lower molar, slightly squarish and much worn, is assigned to Sivapithecus.
Sivapithecus is generally regarded as a highly evolved ape showing certain progressive characters, and Pilgrim attributed a high status for this genus. Other authorities considered the presence of a projecting canine and a seetorialised lower first premolar in addiltion to a simian shelf? as more apelike. Palaeontological evidence so far has not been conclusive and the whole problem now depends on collection of more material for further elucidation.
Stratigraphy and Correlation of the Indravati Series (Purana Group) of Bastar Dt. (M.P.)
Authors: Dutt N. V. B. S. 
Published: November 2024

Abstract
The sequence of the Purana formations of Bastar, in the ascending order of (1) Tiratgarh subarkose and orthoquartzite, with purple shale towards the top, (2) Kanger grey laminated limestone, and (3) Jagdalpur purple shale and shale-limestone, with intercalations of quartzites and limestones, in one conformable series, is established. The name "Indravati Series", is proposed for this succession after the name of the river draining the largest patch where the entire sequence is exposed.
On lithological, successional and structural considerations, the 'Tiratgarh' is correlated with the Paniam of Kurnool and the Chandarpur of Chhattisgarh; the 'Kanger' with the Koilkuntla of Kurnool, and the 'Charmuria' of Chhattisgarh and the 'Jagdalpur' with the Nandyal of Kurnool and the 'Gunderdehi, Khairagarh and Raipur' of Chhattisgarh. The 'Tiratgarh' is tentatively correlated with the Sullavai of the Godavari valley. An upper Kurnool age is thus assigned to the Indravati series.
Various structural considerations indicate that the basin, which was continuous from Sukma to Chhattisgarh, was separated from the basin along the Godavari valley by a landmass with shore lines roughly trending N.W.-S.E. The south-eastern boundary of the Indravatis and the eastern boundary of the Kurnools indicate the limits of the basin in this direction.
Some Aspects of Metamorphism of Sakoli Series around Gangajhiri, Bhandara District, Maharashtra
Authors: Sengupta Amaljyoti 
Published: November 2024

Abstract
The area around Angul (20°50'N, and 85°05'E) at the north-eastern part of the Eastern Ghats belt, is characterised by highly metamorphosed Archaean catazonal meta-sediments which were syntectonically intruded by a group of hitherto unreported igneous rocks, viz. anorthosite, norite, gabbro and acid charnockite suite sensu stricta. The acid charnockites are generally conformable to the country rocks but clearly show intrusive features in several localities. Along with the surrounding country rocks the syntectonic igneous rocks are highly deformed and metamorphosed under hornblende-granulite subfacies condition. A homophanous biotite-granite, pegmatite-vein quartz and dolerites are post-tectonic discordant intrusions. The paper discusses the geological succession of the area with special reference to the relation between deformation, intrusion and metamorphism of the meta-sediments and the igneous rocks. Among the intrusives, anorthosites are early tectonic and charnockites are late tectonic in nature. Emplacement of norites took place during the main phase of deformation and even slightly outlasted the major folding movement. The maximum regional metamorphism took place in the late tectonic period after the emplacement of charnockites and was followed by granitisation of the rocks to some extent. The post-tectonic intrusions do not show any regional metamorphic effect; but the dolerite shows evidence of auto-metamorphism.
On the Origin and Mechanics of Emplacement of Pegmatites and Related Bodies, Gurpa, Gaya District, Bihar
Authors: Das Bhagwan 
Published: November 2024

Abstract
The origin of muscovite-pegmatites in the area around Gurpa, Gaya district, Bihar (India), seems to be associated with syn- to late-kinematic migmatization and granitization connected with Satpura Orogeny. They have been formed by a process of metasomatic replacement, with the proviso, that some may be replacement 'insitu' while others may probably be a 'mobilized replacement'. Various mechanisms of emplacement are indicated, non-displacement and non-mobility being the most significant. The pegmatitic constituents were introduced into the emplacement sites from outside; but local derivation by metamorphic differentiation is not ruled out for some of them.
Uranium in Carbonaceous Clays in Neyveli South Arcot, Madras State
Authors: Venkataraman K. 
Published: November 2024

Abstract
Since some low-rank coals have been found to contain significant amounts of uranium in several countries, the recently exposed Lignite bed at Neyveli, S. Arcot, was examined for its uranium content. Though the lignite itself was found to contain only a poor amount of uranium, a carbonaceous clay bed immediately overlying the lignite showed uranium in amounts varying from .005% to .086%. From the nature of the occurrence and the radio ­ active disequilibrium seen in the clays, the uranium appears to have been emplaced in the clays by groundwater, which leached it from the crystalline rocks to the north and north-west of Neyveli. Uranium is apparently present in the carbonaceous clays as urano ­ organic complex.

Palmoxtlon Mahabalei, A New Petrified Palm Wood from Mohgaon Kalan, India
Authors: Rao A. R. , Menon Vimala K. 
Published: November 2024

Abstract
A petrified monocotyledonous wood from Mohgaon Kalan (M.P.) shows a number of characters with the form genus Palmoxylon. It differs from all known Indian species of this genus, and particularly in that the ventral sclerenchyma of each fibrovascular bundle is more developed than the dorsal and often unites with it to form a sclerenchyma ring. The specimen which may be referred to the "Cocos-like" palms of the combined scheme of Von Mohl and Stenzel has been designated Palmoxylon mahabalei.
The Behaviour of Some Trace Elements in the Alkalic Suite of Koraput, Orissa
Authors: Bose Mihir K. , Sankaran A. V. , Bhattacharya T. K. 
Published: November 2024

Abstract
Geochemical data for 20 igneous rock samples from alkali complex of Koraput, Orissa are presented and discussed. Trace element contents in 8 individual minerals separated from the rock members have been estimated. The abundances of rare alkali earth metals are distinctly higher in early basic and intermediate members compared to those in a calcalkali suite. Some diadochic element ratios reveal a pronounced change of the variation trends at the ultimate end of the fractionation process. The granitophilc elements are not so remarkably enriched in the late differentiates as expected in low melting temperature constituents. Unlike feldspathoidal syenites of agpaitic complex, the nepheline syenite of Koraput is poor in niobium and zirconium.
A Review of the Groundwater Potential and Scope for Future Development in East and West Godavari, Krishna and Guntur Districts of Andhra Pradesh
Authors: Balasundaram M. S. 
Published: November 2024

Abstract
The coastal districts of East and West Godavari, Krishna and Guntur of Andhra Pradesh have an areal extent of 42,264 sq. km., of which an area of 21,801 sq. km is covered by hard crystalline rocks and metamorphosed older sedimentary rocks. An area of 4,826 sq. km comprises of Lower and Upper Gondwana and Tertiary sediments and Deccan Trap formations. Alluvial deposits together occupy the remaining area (i.e. 15,637 sq. km) of the deltaic parts of Krishna and Godavari rivers. Of these, the sedimentary formations along with the alluvial deposits are the most important formations for groundwater development on a large scale by means of tube-wells.
The Government of Andhra Pradesh has drawn up a Package project for constructing 7,500 tube-wells in the upland and deltaic areas of the region to step up agricultural production in the State. There is good scope for large scale development both in the areas occupied by sedimentary formations of the upland region and by alluvial deposits of the deltaic region.
Petrology of Coal, Burnt Coal and Para Lava from Singrauli Coalfield, M. P. & U. P
Authors: Pareek H. S. 
Published: November 2024

Abstract
Extensive drilling operations carried out by the Geological Survey of India and the Indian Bureau of Mines, in the north-eastern portion of Singrauli coalfield, M.P. and V.P., have revealed the existence of several thick and persistent coal seams, named as Kota, in the Karharbaris, Turra and Purewa from the bottom, in the Barakars, and Jhingurdah Top and Jhingurdah Bottom in the Raniganj formations. Petrological studies of the coals representing these seams in cores and from the quarry faces, have been carried out.
The Karharbari and Barakar coals are composed of mainly durite, 'intermediates', and fusite, while the Raniganj coals are essentially vitrinite-rich, being composed of a greater proportion of vitrite, clarite and the' intermediates' than durite and fusite. The mineral matter is thoroughly disseminated in the organic layers, and it is doubtful if mechanical washing methods can improve the quality of coal. The petrographic composition is also unfavourable for making metallurgical coke. The sporinite content is quite high and may be useful for hydrogenation.
The Singrauli coals are similar in petrographic composition to the coals of the adjacent coalfields of Son valley basin. It is also inferred that the Singrauji basin formed a part of the large spread of the Gondwana sediments from Talcher in the east to Singrauli in the west, forming the Son-Mahanadi basin.
The burnt coal occurs at the expected outcrop position of the Purewa seam in asso. ciation with para lava-fused Barakar sandstone. The presence of cristobalite indicates that temperatures up to 1300°C were reached during spontaneous combustion of the coal seam.
