Methods for determining the position of the curve in the plan and the influence of the geometry of the track on the indicators of interaction between the track and the rolling stock

The article substantiates the necessity of supplementing the existing estimate of the track position in the plan by the difference of adjacent bending arrows with an estimate of deviations from the fixed initial position, which ensures the constancy of the characteristics of a single-radius curve or the components of a multi-radius curve along their entire length. As a fixed initial position of the reference base (base position), it is proposed to accept the design position or the position of the track after the repair performed according to the project, and in the absence of the project, the calculated position obtained using verified programs. The question of determining the values of the deviation of the position of the curves at individual points from the base position and their ranking for different variants of recording the curves is considered. As possible options for surveying are considered Geodetic measurement methods using Cartesian and polar coordinate systems, methods of obtaining information from transformed data from sensors of track measuring cars, as well as the classical method of measuring the arrows of the bend of a curve.The article presents the results of calculating the indicators of the interaction between the track and the rolling stock (frame and horizontal transverse forces, lateral deflections of rails) when modeling the motion of a freight car along curves, the parameters of which were obtained on the basis of analysis of data from experimental sections. The calculation results are correlated with the analyzed data on the presence of deviations from the base position in the curves.

German wie-complements

In German, complement clauses embedded by the wh-wordwie(‘how’) have two different readings. The first is a manner reading expressing a manner or method of doing something. The second is calledeventivein this paper because it expresses an event in progress instead of a manner. Ruling out ambiguity ofwie, the question arises of why a manner word is used to express an event in progress. The basic semantic hypothesis in this paper is thatwieexpresses similarity (as it does in, e.g., similes). The paper starts from the observation that in the manner readingwiehas a base position next to the verb and is a modifier of the event type whereas in the eventive reading it is base-generated above VP and thus adds information about the event token. The analysis includes two components: First, manners are considered as sets of similar events (instead of primitive objects), and methods, in particular, are considered as sets of similar sequences of subevents. Secondly, events in progress are seen as initial sequences in sets of similar natural continuations. From this point of view, an event in progress is like a method comprising sequences of subevents that share the same initial part. This analysis provides a semantic interpretation explaining why the wh-wordwieexpresses both the regular manner reading and the eventive reading depending on whether it modifies the event type or the event token.

Non-canonical word order and temporal reference in Vietnamese

The paper revisits Duffield’s (2007) (Duffield, Nigel. 2007. Aspects of Vietnamese clausal structure: Separating tense from assertion. Linguistics 45(4). 765–814) analysis of the correlation between the position of a ‘when’-phrase and the temporal reference of a bare sentence in Vietnamese. Bare sentences in Vietnamese, based on (Smith, Carlota S. & Mary S. Erbaugh. 2005. Temporal interpretation in Mandarin Chinese. Linguistics 43(4). 713–756), are argued to obtain their temporal interpretation from their aspectual composition, and the default temporal reference: bounded events are located in the past, unbounded events at present. It is shown that the correlation so observed in when-questions is superficial, and is tied to the syntax and semantics of temporal modification and the requirement that temporal adverbials denoting future time is base generated in sentence-initial position, and past time adverbials in sentence-final position. A ‘when’-phrase, being temporally underspecified, obtains its temporal value from its base position. However, the correlation between word order and temporal reference in argument wh-questions and declaratives is factual, depending on whether the predicate-argument configuration allows for a telic interpretation or not. To be specific, it is dependent on whether the application of Generic Modification (Snyder, William. 2012. Parameter theory and motion predicates. In Violeta Demonte & Louise McNally (eds.), Telicity, change, and state. Acrosscategorial view of event structure, 279–299. Oxford: Oxford University Press) or accomplishment composition is realized. Canonical declaratives, and argument wh-questions, with telicity inducing material, license GM or accomplishment composition, yielding bounded events, hence past; by contrast, their non-canonical counterparts block GM or accomplishment composition, giving rise to unbounded event descriptions, hence non-past.

This research aimed to determine the physical properties and advantages of cement boards made from sago stem bark waste based on the test results of several parameters according to JIS A 5908 (2003) standard. The results showed that the physical properties of cement board from sago stem bark waste with the addition of the CaCl2 catalyst were good, with the average value of density ranged from 1.19-1.26 gr/cm³, water content 7,67-8,02%, and water absorption after immersion 2 hours 6,03-7.65% as well as after 24-hour immersion 11,62-12,91%, respectively. The averages swelling value of board thickness was 1.62-12,91% after immersion 2 hours and 1.40-3.41% after immersion 24 hours. Furthermore, what sago bark waste in various positions of the tree trunk (tree base, middle and top) can be utilized to manufacture cement board. The board made from sago stem bark waste at the base position with a catalyst CaCl2 6% has the best physical properties and meets JIS A 5908 (2003) standard. Cement board from sago stem bark waste has an excellent waterproof capability and can be used as outdoor materials.

Oblique nominals, a verbal affix and late merge

The goal of this paper is to address the syntax of certain oblique nominals in Blackfoot (Algonquian) that are introduced by a set of verbal prefixes called linkers. In the literature, an oblique nominal introduced by a verbal affix always shows certain properties of objects, e.g., agreement. This type of affix is analyzed as forming a complex verb with the main verb via head movement, and the oblique nominal is treated as an object of the complex verb. However, this paper demonstrates that oblique nominals introduced by linkers in Blackfoot do not show certain object properties even though the linker looks like it forms a complex verb. Building on the lack of object properties, linker phrases are proposed to be adjuncts. As proposed for adjuncts generally (e.g., Stephanov, Arthur. 2001. Late adjunction and minimalist phrase structure. Syntax 4(2). 94–125), this paper proposes a late merge analysis for linker phrases. Within an Agree-based model (Chomsky, Noam. 2000. Minimalist inquiries: The framework. In Roger Martin, David Michaels & Juan Uriagereka (eds.), Step by step: Essays on minimalist syntax in honor of Howard Lasnik, 89–155. Cambridge, MA: The MIT Press, 2001. Derivation by phase. In Michael Kenstowicz (ed.), Ken Hale: A life in language, 1–52. Cambridge: The MIT Press) where the derivation proceeds by phases (Chomsky 2008), a linker phrase, as an adjunct, lacks the relevant features to participate in the derivation via Agree, and thus it merges late at the end of a given phasal derivation such as vP. When spell out applies, the linker linearizes with a [V-v] complex in the base position, i.e., vP, giving its surface appearance as a verbal affix. Under this view, a linker does not lead to formation of a complex verb as it does not undergo head movement to the verb, unlike applicative affixes, consistent with the absence of object properties.

Hvor ‘each’ Reciprocals and Distributives in Icelandic: e-Raising + Short Main Verb Movement

We discuss remarkable constructions in Icelandic that have the distributive pronoun hvor ‘each’ in common: the reciprocal construction hvor annar ‘each other’, and the distributive hvor sinn ‘each their’ construction, which also comes in a sinn hvor ‘their each’ version. We provide the first detailed description of these constructions, in particular their case and word order properties, which raise recalcitrant puzzles, and then we discuss what they tell us about the syntax of nonfinite verbs. Specifically, the word order and case properties of these constructions indicate that nonfinite verbs in Icelandic undergo short verb movement within the verb phrase. That is, the evidence indicates that the leftmost element in these constructions, alternatively hvor or sinn, originates inside an object DP and moves, by what we refer to as e-raising, to the base position of an antecedent with which it agrees, before being stranded by that very antecedent. The verb, nevertheless, appears to the left of this element, even when it is a nonfinite verb, showing that it must undergo short movement to the left of Spec,vP. In addition, the interaction of e-raising and case has important consequences for Case theory, as it indicates that case agreement and case marking take place in PF.

The Submental Nasal Appearance Scale for the Assessment of Repaired Unilateral Complete Cleft Lip: A Validation Study

Objective: To reassess reliability and validity of the Submental Nasal Appearance Scale (SNAS) compared to the preliminary pilot study, for assessment of patient photographs with repaired unilateral cleft lip and palate (UCLP). When utilizing the SNAS, 3 nasal features (1. nasal outline; 2. alar base position; 3. nostril axis) must be graded according to symmetry between the cleft and noncleft side using a 5-point scale with reference photographs for each feature. The mean score calculated from the graded features reflects the overall degree of nasal symmetry, which is considered an important goal when repairing UCLP. Design: Fifty patient photographs were selected and cropped, displaying the submental view. Six raters assessed these photographs using the SNAS and a separate 5-point scale to assess the overall submental appearance. Interrater reliability was determined for both methods and correlation was calculated between these as an indication of construct validity. Setting: Amsterdam UMC, location VUmc, Amsterdam, The Netherlands. Patients: Six- to 9-year-old patients with repaired UCLP. Results: Interrater reliability of 0.73 and 0.48 was found for the SNAS and overall appearance assessment, respectively, while in the pilot study values of 0.79 and 0.69 were found. Correlation of 0.59 and 0.74 was found in the current and pilot study, respectively, between the SNAS and overall appearance assessment. Conclusions: The SNAS is a reliable tool to assess nasal symmetry from the submental perspective. Reliability of the SNAS is higher compared to grading overall appearance, but validity of the SNAS was less well supported.
