Women's language features in Alaa Murabit's speeches
Full text linkAs much as our choice of means of communication is guided by the concepts we wish to communicate, the way we feel about things in the actual world determines how we express ourselves about these things. It means that although two individuals may be considered talking about the same thing, the true meaning they are trying to convey may be unrelated. These differences could lead to sexism and other discriminatory behavior. Women are not always used as informants in linguistic studies. In order to understand why women talk the way they do, it must first be known and understood the distinguishing features and why such features exist. This research analyzed women’s language features found in Alaa Murabit’s speeches. This research discusses two main topics: women’s language found in Alaa Murabit’s speeches and the conformity of language functions to women’s language features. The main theory used in this research is women’s language features theory, which Robin Tolmach Lakoff proposed in her paper “Language and Woman’s Place” (1973). Furthermore, the theory by Judy Pearson (1985) about women’s language functions is also used as a supporting theory to determine the conformity of language functions to women’s language features found in Alaa Murabit’s speeches. Qualitative method with descriptive analysis approach is used in conducting this research. The research objects are four videos containing Alaa Murabit’s speeches uploaded on four different Youtube channels, discussing the topics of women and women’s role in society. The result shows eight out of ten women’s language features found in Alaa Murabit’s speeches: Lexical hedges or fillers, Tag questions, rising intonation on declaratives, empty adjectives, intensifiers, hypercorrect grammar, super-polite forms, and emphatic stress. Based on the analysis, the conformity of language functions to women’s language features is that Alaa Murabit used most features, particularly emphatic stress, to show feelings and opinions. However, she also used lexical hedges or fillers to express uncertainty in her utterances

Computational models for the extrusion-based additive manufacturing
Full text linkThe Fourth Industrial Revolution (4IR) has introduced new business models focused on consumers and product customization. As a natural consequence, both the quantity of the service provided and the added value have increased.
Additive Manufacturing (AM) is one of the nine pillars of 4IR; it enables the production of small batches of customized and lightweight components on demand. In addition, it plays a key role in sustainability, as it offers opportunities to minimize wastes, energy consumption and use eco-friendly materials. In the framework of sustainability, the transportation emissions are lowered by this decentralized and flexible production.
Furthermore, a second key pillar of 4IR is Digital Twin (DT), which indicates a virtual simulation of a real-world machine, product or complex system; in general, DT is based on data collected through a complex network of sensors, to better analyze the behavior of real systems.
However, computer simulations are gaining increasing attention, because of the possibility to analyze quantities that cannot be measured directly and gain a deep insight of physical processes occurring in AM. On the one hand, analytical methods allow for a closed form solution of a given problem with many assumptions. On the other hand, fully numerical methods describe more complex scenarios, but they can be computationally expensive. An intermediate solution is given by the semi-analytical models.
In the present work, different Material Extrusion (MEX) processes have been studied by means of both semi-analytical and fully numerical methods.
In the first part of the dissertation the screw-based MEX, based on the processing of pelletized thermoplastics has been reviewed and studied mathematically; for the first time, a complete model aiming at coupling the screw-barrel and deposited layer dynamics has been formulated. The influence of process parameters on important flow characteristics (i.e., mass flow rate, pressure and melting profile) has been explored.
In the second part, generalized methods to solve the flow in: i) straight cylindrical ducts and ii) tapered cone geometries, usually found as internal geometrical features in the nozzles used in all MEX processes, have been formulated. The first method has been validated with respect to literature data, while the latter has been compared with real force measurement by means of a silicone MEX custom-made setup.
Then, a model for the counterpressure arising under the extrusion head has been developed and validated using the same MEX setup; the composite model (made up of nozzle flow and deposited bead models) showed an accuracy up to 99.7[%] in predicting overall printing force; this paves the way for the application of the proposed methods in other MEX processes modeling, control and optimization
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Comparison of AlaA with structurally homologous enzymes.
No full text<p>(<b>A</b>) Phylogenetic tree based on structure-based multiple sequence alignments of AlaA obtained from PDBeFold <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0102139#pone.0102139-Krissinel1" target="_blank">[58]</a>. Functionally related enzymes are shaded in like colors; alanine transaminases in gold, tyrosine aminotransferases (TyrAT) in cyan, aspartate aminotransferases (AspAT) in pink, kynurenine aminotransferases (KAT) in green, aspartate decarboxylases (CobD, AspDC, in orange), histidinol phosphate aminotransferases (HspAT) in grey; other transaminases of unknown function or with unique substrate preferences are not shaded. (<b>B</b>) Cartoon representation of alanine transaminases of known structure, highlighting the overall fold structure, catalytic residues, cofactor status and N-terminal motifs of AlaA (PLP, acetate), <i>Pf</i>AlaAT (PMP, PDB 1xi9), <i>Hv</i>AlaAT (DCS, PDB 3tcm) and human ALT2 (PLP, PDB 3ihj). In AlaA and <i>Hv</i>AlaAT the N-terminal H1-plug-H2 motifs are fully structured, whereas in <i>Pf</i>AlaAT and ALT2 different segments of the N-terminal arm are disordered. The most representative <i>Pf</i>AlaAT monomeric structure (present in three out of four copies in the crystal asymmetric unit) lacks interpretable electron density for the eight-residue segment (from Ala14 to Leu20, delimited by orange spheres) spanning the plug. In ALT2, the N-terminal 65-amino-acid residues fold into a long β-hairpin structure that swaps domain and extends toward the opposite subunit (the start and end of the swapped β-hairpin are marked with asterisks), partially covering the active site cavity and ending in a ten-residue unstructured segment (spanning Ile95 to Gln104 until the anchor Pro105 residue). This disordered region (delimited by yellow spheres) is also located over the substrate-binding pocket and therefore may have functional and structural roles akin to those of the plug motif described in AlaA and <i>Pf</i>AlaAT.</p
