Abstract
Threaded cups show good clinical results when implanted correctly. In clinical use, multiple cases with an incomplete placement of the EcoFit threaded cup (implantcast) were observed. This behaviour could not be explained intra- and postoperatively. The aim of this study was to compare and optimise the drill-in-behaviour of the EcoFit cup in a biomechanical investigation. EcoFit cup sizes 46, 50 and 54 mm were compared with the SC cup (Aesculap) size 50 mm. Foam blocks (Sawbones) of density 0.16 g/ml (pcf 10), 0.32 g/ml (pcf 20) and 0.48 g/ml (pcf 30) were used. After standardised placement using a universal testing system (n = 8 per group), the primary stability, the overhang of the cups and the drill-in behaviour were measured. Overreamings of 1 and 2 mm were performed (pcf 20, n = 8) for the EcoFit cup size 50 and the primary stability as well as the overhang measurements were examined. Measurements of the cup diameter, thread depth and thread pitch were performed on three-dimensional (3D) images of the cup size 50 mm. The drill-in behaviour was different between the EcoFit and the SC cups. Even with maximum torque, the EcoFit cup could not be positioned as deep as the SC cup in standard reaming conditions (overhang of 1.1 ± 0.4 mm for the EcoFit size 50 in pcf 20 and of −0.01 ± 0.2 mm for the SC cup). The primary stability was lower for the EcoFit cup in comparison to the SC cup (128.8 ± 3.2 Nm vs. 138.6 ± 9.1 Nm, p = 0.0291). With overreaming to 51 mm, a deeper positioning of the EcoFit was possible (overlap of −0.3 ± 0.1, comparable to the SC cup). The overreaming of the cavity also led to a significantly higher primary stability of 143.4 ± 3.7 Nm (p < 0.001) comparable to the unaltered condition (128.8 ± 3.2 Nm). Overreaming to 52 mm had no further advantage in terms of primary stability or overhang. The geometric measurements showed significant differences as well. The previously clinically observed difficulties in inserting the cup were confirmed by this study. By overreaming to 51 mm, the drill-in behaviour, the primary stability and the measured overhang were comparable to the reference cup. The obtained results suggest that the extension of the acetabulum cavity to 51 mm while using the implantcast EcoFit size 50 should be implemented in clinical applications.
A simulation model for the need for intra-plant transport operation planning by AGV

Published: December 2019

Abstract
Intra-plant transport has an important role in the systems of enterprise logistics. At present, automated transport systems (AGV) are used for its efficient operation, with minimal operator attendance. For the proper and reliable functioning of such a transport system, there is currently a wide range of methods, of which the method of computer simulation is increasingly dominant. In the application, however, it is necessary to take into account that the functioning of AGV systems is a very demanding process with high demands on the used simulation software. Within the article, it will be described the use of the method of additional programming, as an effective tool in the creation of a simulation model of the AGV system for the need of its planning. The model presents the possibilities of increasing of the output of the analyzed production process to more than 70%, and at the same time it indicates insufficient use of workplaces that in one case reaches the value about 10%. The application of this model pointed to the reduction of the number of workplaces by one and with this related increase of output of other workplace.

Kraft lignin reaction with paraformaldehyde
Authors: Paananen Hanna , Pakkanen Tuula T. 
Published: December 2019

AbstractLignin is the second most abundant biopolymer and will be an important source for carbon-containing compounds in the future. Based on their similar phenolic structures, lignin has great potential to become a valuable substitute for phenol in phenol-formaldehyde resin adhesives. To meet this aim, the sodium hydroxide (NaOH)-catalyzed reaction of kraft lignin with formaldehyde was studied by using paraformaldehyde (PFA) as a formaldehyde source. The advantage of using PFA, the solid polymer of formaldehyde, is the simple composition of the depolymerized solution. According to the results of differential scanning calorimetry (DSC), the lignin reaction was found to require a high NaOH concentration in order for the reaction with PFA to proceed at reasonably low temperatures compared to the curing temperature of phenol-formaldehyde resins (approximately 150°C). On the other hand, high alkalinity conditions are known to favor the disproportionation of formaldehyde to formic acid and methanol. Due to the moderate reactivity of lignin, the Cannizzaro reaction can compete with the methylolation reaction of lignin. Based on the results of13C,31P and1H-13C heteronuclear single quantum correlation nuclear magnetic resonance (HSQC NMR), methylolation was found to be the main reaction occurring in the lignin-formaldehyde reaction.

Dàgáárè complex constructions: Serial verb constructions, multi-aspectual constructions and coordination
Authors: Angsongna Alexander 
Published: December 2019

Abstract
The Serial Verb Construction (SVC) phenomenon is widely researched across many languages. It is generally regarded as a construction in which two or more verbs share the same arguments within a single clause. The verbs in the series must share some grammatical properties such as tense, aspect and polarity. However, there is a verb sequence construction in Dàgáárè that shows apparent similarities to SVCs but with different values for aspect on the verbs. This paper investigates the internal structure of Dàgáárè SVCs and other verb sequence constructions such as multi-aspectual constructions (MACs) and coordinate structures. Applying a variety of syntactic and semantic tests, the paper distinguishes SVCs from MACs and coordination and shows the relation between MACs and coordination. Based on the results of the tests, I argue that although MACs have some properties of SVCs, they are not SVCs. Rather; I conclude that MACs pattern with coordination or covert coordination in Dàgáárè and they are perceived to express distinct events.
The syntax and semantics of helping: Sociative causation in Kinande
Authors: Schneider-Zioga Patricia , Mutaka Philip Ngessimo 
Published: December 2019

Abstract
We investigate the syntax and semantics of the sociative causative in Kinande (D42), a Bantu language spoken in eastern DRC. We present our discovery that Kinande, apparently unique among Bantu languages, grammaticalizes this type of causation with a specialized morpheme. In sociative causatives, the causer causes through social interaction rather than physical manipulation (direct causation) or words (indirect causation). We propose sociative causation in Kinande more exactly means ‘y carries out a subevent of P to help x do P.’ Helping here is by doing and is not comitative: rather, it is partitive – each actor does part of the action. This accounts for the classes of verbs that can undergo sociative causation. We establish that the construction is mono-clausal and note that the sociative morpheme is closely related to the benefactive applied morpheme. A second extension that occurs in this construction marks transitivity. We observe that the transitive extension can co-occur with the passive extension which tells us there is more than one voice projection in Kinande. Finally, we look more closely at the partitive reading of the caused event and note that the partitivity can be morpho-syntactically manifested either through partitive marking of the object of the caused event or through partitive marking of the caused event itself.
Manual Labour and Biblical Reading in Late Medieval France
Authors: Hoogvliet Margriet 
Published: December 2019

Abstract
This article discusses artisans and people doing manual work in the French-speaking areas of Western Europe who owned and read the Bible or parts of its text during the late Middle Ages and the early sixteenth century. The historical evidence is based on post-mortem inventories from Amiens, Tournai, Lyon, and the Toulouse area. These documents show that Bibles were present in the private homes of artisans, some of them well-to-do, but others quite destitute. This development was probably related to a shift in the cultural representation of manual work in the same period: from a divine punishment into a social space of religion. The simple artisan life of the holy family, as imagined based upon the Gospel text, and their religious reading practices were recommended as an example to follow by both lay people and clerics.
Framing Biblical Reading Practices: The Impact of the Paratext of Jacob van Liesvelt’s Bibles (1522–1545)
Authors: Hoff Renske Annelize 
Published: December 2019

Abstract
The production and reception of early modern vernacular Bibles was not a uniform enterprise: printed scripture appeared in different sizes, translations, confessional colours, layout, and content. Through the analysis of the paratextual material in several Dutch Bible editions, this paper aims to determine whether different editions stimulated and framed different biblical reading practices, with a focus on complete Bibles and New Testaments published between 1522 and 1544 by the Antwerp printer Jacob van Liesvelt. The comparison of the paratextual features of Van Liesvelt’s complete Bibles and his other, smaller editions, shows that both types animated non-canonical, discontinuous and essentially active reading. However, whereas Van Liesvelt’s New Testaments seemed to encourage the reader to approach the book as a practical tool in his or her daily life, shaped by the rhythm of the zodiac and liturgy, the paratextual features of the complete Bibles facilitate a studious, almost encyclopaedic reading of the book.
Sudden sex hormone withdrawal and the effects on body composition in late pubertal adolescents with gender dysphoria
Authors: Ghelani Rahul , Lim Cheryl , Brain Caroline , Fewtrell Mary , Butler Gary 
Published: December 2019

Abstract

Background
Sex hormones initiate profound physical and physiological changes during the pubertal process, but to what extent are they responsible for continuing the body composition changes of late adolescence and what happens to body composition on sudden sex hormone withdrawal?

Methods
Thirty-six healthy, phenotypically and chromosomally normal late and post-pubertal individuals aged 15–17 years with gender dysphoria (transgirls – birth-registered males identifying as female n = 11; and transboys – birth-registered females identifying as male n = 25) underwent Tanita body composition analysis at 0, 6 and 12 months during reproductive hormone suppression with Triptorelin as part of the standard therapeutic protocol.

Results and conclusions
In the transgirl cohort, paired t-test analysis demonstrated a significant decrease in height and lean mass standard deviation scores over the 12-month period, going against an expected trajectory over that time. In contrast, oestrogen suppression appeared not to affect the body composition of transboys; their measurements were not significantly different at baseline and after 12 months of treatment. The withdrawal of sex hormone secretion does not appear to have a significant impact on female post-pubertal body composition, in contrast to that seen at the menopause. This suggests that other factors may preserve normal body balance in adolescents in the absence of sex steroids.
Pathogenic/likely pathogenic variants in theSHOX,GHRandIGFALSgenes among Indian children with idiopathic short stature
Authors: Kumar Anil , Jain Vandana , Chowdhury Madhumita Roy , Kumar Manoj , Kaur Punit , Kabra Madhulika 
Published: December 2019

AbstractBackgroundOur objective was to estimate the prevalence of pathogenic/likely pathogenic variants in theSHOX,GHR, andIGFALSgenes among Indian children with idiopathic short stature (ISS), and assess the genotype-phenotype correlation.MethodsWe recruited 61 children with short stature, who were born appropriate for gestational age, had no obvious dysmorphism or disproportion, and in whom step-wise investigative work-up (including provocative growth hormone test) was normal. Multiplex ligation-dependent probe amplification was undertaken for identifying deletions/duplications in theSHOXgene. Bidirectional sequencing was performed for identifying variants in theSHOXandGHRgenes in all, and for theIGFALSgene in those with serum insulin-like growth factor-1 (IGF-1) <−1 standard deviation. The genotype-phenotype correlation was studied.ResultsFour children (6.5%) had pathogenic heterozygous variants in theSHOXgene, with one child each having duplication of exon 5, splice site point variant c.278-1G > C in exon 3, partial deletion and complete deletion. None of the patients had pathogenic variants in theGHRgene. Of the 39 patients in whom theIGFALSgene was sequenced, novel heterozygous likely pathogenic variants were found in two children. One had the frameshift variant c.764_765insT, p.A265Gfs*114. The second had the missense variant c.1793G > A, p.R598H predicted by MutationTaster as ‘disease causing’, and indicated by the protein-modelling study as having compromised binding with IGF-1 and insulin-like growth factor binding protein-3 (IGFBP-3) due to altered conformation of the interacting loop.ConclusionsPathogenic variants in theSHOXandIGFALSgenes account for a significant proportion of Indian children with ISS. Further molecular studies using next generation sequencing are needed to gain insight into pathophysiological mechanisms and effective treatment strategies for ISS.

Published: December 2019

Abstract
Based on two adult specimens collected in the Río León (Azuay, Ecuador), we describe a new highland species of a small crab-eating rat of the genus Ichthyomys Thomas (Rodentia, Cricetidae, Ichthyomyini). It is distinguishable from Ichthyomys hydrobates (Winge, 1891), the species phenetically closest to it, by its smaller size, bicolored tail (unicolored in I. hydrobates), broad and heavily fringed hindfoot (narrower and moderately fringed in I. hydrobates), and several craniodental traits (e.g. rostrum short broad; nasals anteriorly truncated; interorbital region narrow; supraorbital margins smoothly rounded; supraorbital foramina small, zygomatic plate very narrow; incisors opisthodont; length of M3 half that of M2). The new species occurs in the western Andes in southern Ecuador and is allopatric with Ichthyomys stolzmanni Thomas, 1893, which also has a bicolored tail but is larger. The new species brings the number of Ecuadorean Ichthyomys to four, Ecuador thus becoming the country with the greatest diversity of Ichthyomyini (four genera and eight species).
The “corpse bride” strikes again: first report of the Davian behaviour in the Eurasian badger
Authors: Colombo Marco , Mori Emiliano 
Published: December 2019

AbstractWe reported the first record of Davian behaviour (necrophilia) in the Eurasian badgerMeles meles(L., 1758) in northern Italy. A male badger was observed in a camera-trap survey courting and trying to copulate with a probably road-killed female, in February. The dead female was a sexually mature, adult individual; the male was probably a young mature individual. Social behaviour of this carnivore may have evolved to guarantee the access to females only to the dominant male. Usually, female badgers passively receive mating by excited males. This behaviour may have enticed the young male to start courtship and copulation with the road-killed female.

Abstract
A 2.5-year study was conducted to understand the fitness of Mastomys natalensis in an agroecosystem in relationship with environmental predictors. The study was conducted in Mayuge district, in the Lake Victoria Crescent zone in Eastern Uganda. Fitness was measured in terms of survival, maturation and capture probability and estimated using multi-event capture-recapture models. Survival rates were higher after high rainfall in the previous month and increased with increasing population density of the animals. Maturation rate, on the other hand, showed no significant association with any predictor variables, while capture probability was significantly associated with sex of the animals, with higher capture probability for males. The results demonstrate that the fitness of M. natalensis in an agroecosystem is dependent on rainfall, sex and current population density. The aforementioned results were associated with increasing vegetation which provides cover for animal nesting and abundant food for the animals during rainfall periods and thus increased survival, high mobility in males in search for mates thus exposing animals to high chances of being captured and increased prey saturation at high population density resulting in high animal survival. These results have important implications for the timing of management strategies, i.e. control efforts should be enforced during the rainfall seasons to prevent high population buildup in the succeeding seasons.

Abstract
In this paper, we consider an almost periodic commensal symbiosis model with nonlinear harvesting on time scales. We establish a criterion for the existence and uniformly asymptotic stability of unique positive almost periodic solution of the system. Our results show that the continuous system and discrete system can be unify well. Examples and their numerical simulations are carried out to illustrate the feasibility of our main results.

Does Digital Exclusion Undermine Social Media’s Democratizing Capacity?
Authors: Mutsvairo Bruce , Ragnedda Massimo 
Published: December 2019

Abstract
Claims have been made that the advent of social media and its assumed ability to fuel social strife and organize anti-government protests has empowered people around the world to successfully challenge repressive authorities. However, in an era in which several issues ranging from digital colonialism to digital exclusion among other challenges, have become so dominant, it is our role as researchers to question some of these claims especially when they seem unsubstantiated. Sharing or finding solidarity is something that can be done on social media platforms but nothing is as critical as being part of the digital community. In that regard, questions surrounding digital exclusion are critical especially when discussing the extent to which social media influences democracy, questions that several scholars from every corner of the world are currently seized with. In this article, we not only identify social media’s potential but we also probe problems associated with beliefs that digital networks have the capacity to support democratization. Contemporary societies should be asking what the real gains of the fall of the Berlin Wall are in the work of these fundamental digital shifts, which have left both negative and positive outcomes on all countries including established Western democracies.
