description: Astrometric accuracy of complex modern VLBI arrays cannot be calculated analytically. We study the astrometric accuracy of phase-referenced VLBI observations for the VLBA, EVN and global VLBI array by simulating VLBI data for targets at declinations -25$^\circ$, 0$^\circ$, 25$^\circ$, 50$^\circ$, 75$^\circ$ and 85$^\circ$. The systematic error components considered in this study are calibrator position, station coordinate, Earth orientation and troposphere parameter uncertainties. We provide complete tables of the astrometric accuracies of these arrays for a source separation of 1$^\circ$ either along the right ascension axis or along the declination axis. Astrometric accuracy is 50microas at mid declination and is 300microas at low (-25$^\circ$) and high (85$^\circ$) declinations for the VLBA and EVN. In extending our simulations to source separations of 0.5$^\circ$ and 2$^\circ$, we establish the formula for the astrometric accuracy of the VLBA: Delta = (Delta_1$^\circ$-14)*d+ 14 (microas) where Delta_1$^\circ$ is the astrometric accuracy for a separation d=1$^\circ$ provided in our tables for various declinations and conditions of the wet troposphere. We argue that this formula is also valid for the astrometric accuracy of the EVN and global VLBI array.

description: Aims. We report the INTEGRAL/IBIS observations of the Coma Cluster in the hard X-ray/soft-ray domain. Methods. Since the Coma Cluster appears as an extended source, its global intensity and significance cannot be directly extracted with standard coded mask analysis. We used the method of imaging the extended sources with a coded mask telescope developed by Renaud et al. (2006). Results. The imaging capabilities and the sensitivity of the IBIS/ISGRI coded mask instrument allows us to identify for the first time the site of the emission above ~ 15 keV. We have studied the Coma Cluster morphology in the 18-30keV band and found that it follows the prediction based on X-ray observations.We also bring constraints on the non-thermal mechanism contribution at higher energies.

description: The subject of this master thesis is the study for the enhancement and promotion of a historical place, which is the Macedonia front. The Macedonia or Salonica front was one of the main bases of the war operations, which were formed in the area of the Balkans, during the period of the First World War, which broke out in Europe at the beginning of July 1914. This master thesis focuses in the monuments which are located in the counties of Thessaloniki, Kilkis and Serres, while the monuments themselves are allied forces cemeteries and commonwealth graves and also memorials. The master thesis is structured in four parts. The first part includes the historical information about the period of the First World War. In the second part are listed the monuments of the Macedonia front which are located in Greece, in the counties of Thessaloniki, Kilkis and Serres. In the third part of the thesis are put forward the comments and theoretical proposals, whose target is the achievement of the enhancement and the promotion of the monuments. In the beginning of the third part there is an introduction about the management of cultural heritage and its targets and after that follows the management plan which is proposed to be applied in this case. In the last part are mentioned the conclusions of the whole study.

description: The transition from partial to complete spin polarization of two-dimensional electrons at half filling of the lowest Landau level has been studied using resistively-detected nuclear magnetic resonance (RDNMR). The nuclear spin-lattice relaxation time is observed to be density independent in the partially polarized phase but to increase sharply at the transition to full polarization. At low temperatures the RDNMR signal exhibits a strong maximum near the critical density.

description: G-quadruplexes (G4) are secondary structures present in DNA and RNA. A G4 is defined by a stack of G-tetrads, which are plans composed of four guanines linked by Hoogsteen base pairs. Studies on RNA G4 (rG4) have shown their roles in many regulation of mechanisms like the translation, the alternative splicing, the polyadenylation, the mRNA location and the miRNA maturation. G4 can act as activators or as inhibitors on regulations. These effects depend on the transcript in which the G4 is located but also on the location of the G4 in the transcript, for instance in coding regions or non coding regions. The variety of functions for G4 makes it complex to fully understand rG4 functionality. Thus, studying rG4 evolution across several transcriptomes shall lead to a better understanding of G4 apparition and spread during evolution. Diverse species of each life domain have been chosen for this study of rG4 conservation. rG4 are predicted in transcriptomes of species. Then the distribution of predicted rG4 is analysed to assess their importance in transcriptomes, and also understand their evolution and involvement in cellular mechanisms.
Cosmological Perturbations in Non-Commutative Inflation

description: We compute the spectrum of cosmological perturbations in a scenario in which inflation is driven by radiation in a non-commutative space-time. In this scenario, the non-commutativity of space and time leads to a modified dispersion relation for radiation with two branches, which allows for inflation. The initial conditions for the cosmological fluctuations are thermal. This is to be contrasted with the situation in models of inflation in which the accelerated expansion of space is driven by the potential energy of a scalar field, and in which the fluctuations are of quantum vacuum type. We find that, in the limit that the expansion of space is almost exponential, the spectrum of fluctuations is scale-invariant with a slight red tilt. The magnitude of the tilt is different from what is obtained in a usual inflationary model with the same expansion rate during the period of inflation. The amplitude also differs, and can easily be adjusted to agree with observations.

Symmetry in protein complexes

Publisher: name: F1000 Research Limited
Year: 2019

description: Many protein complexes in the Protein Data Bank (PDB) are symmetric homo-oligomers. Indeed, it appears that large symmetrical protein structures have evolved in many organisms because they carry specific morphological and functional advantages compared to small individual protein molecules. There is therefore considerable interest in studying and modeling these structures. Recently we have proposed a novel free-docking method for protein complexes with arbitrary point-group symmetry. Later on we discovered that the inverse problem, i.e. identification of symmetry in a protein assembly, is even more interesting. Given a structure of the assembly, it consists in the identification of the symmetry measure, and also of the computations of the symmetry axes using geometrical considerations or deep neural networks.
Turbulence in the Molecular Interstellar Medium

description: The observational record of turbulence within the molecular gas phase of the interstellar medium is summarized. We briefly review the analysis methods used to recover the velocity structure function from spectroscopic imaging and the application of these tools on sets of cloud data. These studies identify a near-invariant velocity structure function that is independent of local the environment and star formation activity. Such universality accounts for the cloud-to-cloud scaling law between the global line-width and size of molecular clouds found by Larson (1981) and constrains the degree to which supersonic turbulence can regulate star formation. In addition, the evidence for large scale driving sources necessary to sustain supersonic flows is summarized.

title: Kantian constructivism : a restatement
Creators: name: Schaab, Janis David
Publisher: name: University of St Andrews
Year: 2019

description: This thesis provides a restatement of Kantian constructivism, with the aim of avoiding some of the objections and clearing up some of the ambiguities that have haunted previous versions of the view. I restate Kantian constructivism as the view that morality’s normativity has its source in the form of second-personal reasoning, a mode of practical reasoning in which we engage when we address demands person-to-person. By advancing a position about the source of moral normativity, Kantian constructivism addresses a metaethical question, albeit one that is distinct from the questions that many traditional metaethical positions, such as moral realism, focus on. Kantian constructivism has an advantage over competing views of the source of moral normativity when it comes to answering the so-called Normative Question, which I interpret as the question of why we are rationally required to do what we take to be our moral obligation. Kantian constructivism can answer this question because, unlike its competitors, it does not conceive of practical reason as a receptive faculty that is determined by external inputs. Instead, it regards the very form of second-personal reasoning as grounding the fact that morality is normative, thus explaining morality’s rational authority. Although second-personal reasoning is fundamentally distinct from the merely first-personal mode of reasoning that we must engage in insofar as we are agents, all those agents whom we would ordinarily consider bound by moral obligations seem to engage in it. Indeed, although it involves irreducibly second-personal notions, such as accountability and the authority to address legitimate demands, second-personal reasoning is not to be mistaken for a social practice. Instead, it can be applied to purely self-regarding contexts, such as that of committing oneself to a personal project and thereby holding oneself accountable for pursuing it, as well as to interactions with others.

Poisson-Bracket Approach to the Dynamics of Bent-Core Molecules

description: We generalize our previous work on the phase stability and hydrodynamic of polar liquid crystals possessing local uniaxial $C_{\infty v}$-symmetry to biaxial systems exhibiting local $C_{2v}$-symmetry. Our work is motivated by the recently discovered examples of thermotropic biaxial nematic liquid crystals comprising bent-core mesogens, whose molecular structure is characterized by a non-polar body axis $({\bf{n}})$ as well as a polar axis $({\bf{p}})$ along the bisector of the bent mesogenic core which is coincident with a large, transverse dipole moment. The free energy for this system differs from that of biaxial nematic liquid crystals in that it contains terms violating the ${\bf{p}}\to -{\bf{p}}$ symmetry. We show that, in spite of a general splay instability associated with these parity-odd terms, a uniform polarized biaxial state can be stable in a range of parameters. We then derive the hydrodynamic equations of the system, via the Poisson-bracket formalism, in the polarized state and comment on the structure of the corresponding linear hydrodynamic modes. In our Poisson-bracket derivation, we also compute the flow-alignment parameters along the three symmetry axes in terms of microscopic parameters associated with the molecular geometry of the constituent biaxial mesogens.

Populism and the Reform Party
Creators: name: Clough, Derrick C.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis endeavours to answer the question, “What does the Reform Party’s ‘populism’ consist of?” An attempt is made herein to characterize the nature of the Reform Party’s populism via Margaret Canovan’s typology of populisms. The analysis concludes that the Reform Party manifests the characteristics of two of the seven different kinds of populist phenomena that Canovan identifies. It is found, on the one hand, that through his “antipolitical” rhetorical orientation, Reform Party leader Preston Manning evinces a certain form of what Canovan refers to as “politicians’ populism.” On the other hand, it is posited that the party’s policies vis a vis federal bilingualism, multiculturalism and immigration programs reflect Canovan’s conception of “reactionary populism.”
An accreting stellar binary model for active periodic fast radio bursts

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: In this work, we propose an accreting stellar binary model for understanding the active periodic fast radio bursts (FRBs). The system consists of a stellar compact object (CO) and a donor star (DS) companion in an eccentric orbit, where the DS fills its own Roche lobe near the periastron. The CO accretes the material from the DS and then drive relativistic magnetic blobs. The interaction between the magnetic blobs and the stellar wind of the DS produces a pair of shocks. We find that both of the reverse shock and the forward shock are likely to produce FRBs via synchrotron maser mechanism. We show that this system can in principle sufficiently produce highly active FRBs with a long lifetime, and also can naturally explain the periodicity and the duty cycle of the activity as appeared in FRBs 180916 and 121102. The radio nebula excited by the long-term injection of magnetic blobs into the surrounding environment may account for the associated persistent radio source. In addiction, we discuss the possible multi-wavelength counterparts of FRB 180916 in the context of this model. Finally, we encourage the search for FRBs in the ultraluminous X-ray sources.

Ten themes of viscous liquid dynamics

Publisher: name: arXiv
Year: 2006
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: Ten "themes" of viscous liquid physics are discussed with a focus on how they point to a general description of equilibrium viscous liquid dynamics (i.e., fluctuations) at a given temperature. This description is based on standard time-dependent Ginzburg-Landau equations for the density fields, stress tensor fields, potential energy density field, and fields quantifying molecular orientations. One characteristic aspect of the theory is that density has the appearance of a non-conserved field. Another characteristic feature is long-wavelength dominance of the dynamics, which not only simplifies the theory by allowing for an ultra-local Hamiltonian (free energy), but also explains the observed general independence of chemistry. Whereas there are no long-ranged static (i.e., equal-time) correlations in the model, there are important long-ranged dynamic correlations on the alpha time scale.

description: We study the short distance behaviour of euclidean quantum gravity in the light of Weinberg's asymptotic safety scenario. Implications of a non-trivial ultraviolet fixed point are reviewed. Based on an optimised renormalisation group, we provide analytical flow equations in the Einstein-Hilbert truncation. A non-trivial ultraviolet fixed point is found for arbitrary dimension. We discuss a bifurcation pattern in the spectrum of eigenvalues at criticality, and the large dimensional limit of quantum gravity. Implications for quantum gravity in higher dimensions are indicated.

Year: 2007
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We present an improved form of the integration technique known as NDIM (Negative Dimensional Integration Method), which is a powerful tool in the analytical evaluation of Feynman diagrams. Using this technique we study a $% ϕ^{3}\oplus ϕ^{4}$ theory in $D=4-2ε$ dimensions, considering generic topologies of $L$ loops and $E$ independent external momenta, and where the propagator powers are arbitrary. The method transforms the Schwinger parametric integral associated to the diagram into a multiple series expansion, whose main characteristic is that the argument contains several Kronecker deltas which appear naturally in the application of the method, and which we call diagram presolution. The optimization we present here consists in a procedure that minimizes the series multiplicity, through appropriate factorizations in the multinomials that appear in the parametric integral, and which maximizes the number of Kronecker deltas that are generated in the process. The solutions are presented in terms of generalized hypergeometric functions, obtained once the Kronecker deltas have been used in the series. Although the technique is general, we apply it to cases in which there are 2$ $or$ $3 different energy scales (masses or kinematic variables associated to the external momenta), obtaining solutions in terms of a finite sum of generalized hypergeometric series de 1 and 2 variables respectively, each of them expressible as ratios between the different energy scales that characterize the topology. The main result is a method capable of solving Feynman integrals, expressing the solutions as hypergeometric series of multiplicity $(n-1) $, where $n$ is the number of energy scales present in the diagram.

description: The safety which is provided by the railway network is of great importance and its improvement is directly related to the cost of additional measures which are under implementation. The relationship between the cost of an operation on the railway infrastructure and the improvement of the safety provided is difficult to quantify. In this research, is formed and proposed a methodological approach which includes the correlation of the cost needed to implement various measures to deal with incidents that take place in a railway network with a new level of safety achieved. This research is a first attempt to answer this important for railway undertakings research field as many points should be explored further. This study develops and suggests a methodological approach that enables rail companies to correlate the cost that they would spend on additional measures to improve the safety of the system operated by reducing incidents will be achieved and thus the economic benefit that would have. In particular, this paper proposes a method for calculating the frequency and severity of incidents. In this context, it is useful for managers of rail infrastructure and operators, for scholars of Transportation and the various investment bodies.

description: A full spectral survey was carried out towards the Giant Molecular Cloud complex, Sagittarius B2 (Sgr B2), using the ISO Long Wavelength Spectrometer Fabry-Perot mode. This provided complete wavelength coverage in the range 47-196 um (6.38-1.53 THz) with a spectral resolution of 30-40 km/s. This is an unique dataset covering wavelengths inaccessible from the ground. It is an extremely important region of the spectrum as it contains both the peak of the thermal emission from dust, and crucial spectral lines of key atomic (OI, CII, OIII, NII and NIII) and molecular species (NH3, NH2, NH, H2O, OH, H3O+, CH, CH2, C3, HF and H2D+). In total, 95 spectral lines have been identified and 11 features with absorption depth greater than 3 sigma remain unassigned. Most of the molecular lines are seen in absorption against the strong continuum, whereas the atomic and ionic lines appear in emission (except for absorption in the OI 63 um and CII 158 um lines). Sgr B2 is located close to the Galactic Centre and so many of the features also show a broad absorption profile due to material located along the line of sight. A full description of the survey dataset is given with an overview of each detected species and final line lists for both assigned and unassigned features.

Directed mutational analysis of the Rhodobacter capsulatus puha gene and downstream open reading frames
Creators: name: Wong, Danny Ka-Ho
Publisher: name: University of British Columbia
Year: 2009

description: Two mutant strains of Rhodobacter capsulatus which lacked the heavy (H) subunit of the reaction center (RC) were constructed. One strain, DW5, contains a translationally in-frame deletion of the puhA gene, which encodes the RC H subunit. The other strain, DW1, is a puhA polar mutation strain containing the same deletion of the puhA gene coupled with the insertion of a streptomydn/spectinomycin resistance omega (Ω) cartridge. Both strains were unable to grow under photosynthetic conditions (PS ). Absorption spectroscopy and SDS-PAGE analysis showed that these two strains have a reduction in the amount of the light-harvesting I (LHI) complex. In DW5, both photosynthetic growth and LHI complex level were restored by complementation in trans with plasmid pPUHA, which contains the puhA gene. However, when pPUHA was introduced into DW1, photosynthetic growth was only partially restored, and the LHI complex level was not restored to the wild type phenotype. When DW1 was doubly complemented with pPUHA and pORF214/162b (which contains orf214 and orfl62b, two open reading frames [orfs] downstream of puhA), photosynthetic growth was restored to the wild type level. However, LHI complex level was not restored in this doubly complemented strain. In a third mutant strain, DW2, orf214 was directly mutated with an insertion of the Ω. cartridge. DW2 also showed a PS" phenotype and a reduction in LHI complex level. Interestingly, SDS-PAGE analysis showed that the RC H subunit was missing in the intracytoplasmic membrane of DW2. Photosynthetic growth, but not LHI complex level, was restored when DW2 was complemented with pORFF214/162b. The roles of the RC H subunit and the gene products of the orfs downstream of puhA in photosynthesis are discussed.
The targum (1950:Oct. 3 - 1950:Oct. 31)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1950

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Affinity maturation of antibodies during immune responses is achieved by multiple rounds of somatic hypermutation and subsequent preferential selection of those B cells that express B cell receptors with improved binding characteristics for the antigen. The mechanism underlying B cell selection has not yet been defined. By employing an agent-based model, we show that for physiologically reasonable parameter values affinity maturation can neither be driven by competition for binding sites nor antigen -- even in the presence of competing secreted antibodies. Within the tested mechanisms, only clonal competition for T cell help or a refractory time for the interaction of centrocytes with follicular dendritic cells are found to enable affinity maturation while generating the experimentally observed germinal center characteristics and tolerating large variations in the initial antigen density.

description: The essay identifies the notion of eclecticism as pivotal to Dorfles’ aesthetic research. A plurality of skills that has been traced since his formation and that generates the identikit of Dorfles as a restless explorer of contemporary languages: Dorfles as a critic, Dorfles as a scholar of aesthetics, Dorfles as a researcher of costume, industrial design, fashion, Dorfles as a painter and ceramist, Dorfles as a poet, Dorfles as an amateur musician, and even before all of that: Dorfles as a doctor and psychiatrist.

description: Ready access to emerging databases of gene annotation and functional pathways has shifted assessments of differential expression in DNA microarray studies from single genes to groups of genes with shared biological function. This paper takes a critical look at existing methods for assessing the differential expression of a group of genes (functional category), and provides some suggestions for improved performance. We begin by presenting a general framework, in which the set of genes in a functional category is compared to the complementary set of genes on the array. The framework includes tests for overrepresentation of a category within a list of significant genes, and methods that consider continuous measures of differential expression. Existing tests are divided into two classes. Class 1 tests assume gene-specific measures of differential expression are independent, despite overwhelming evidence of positive correlation. Analytic and simulated results are presented that demonstrate Class 1 tests are strongly anti-conservative in practice. Class 2 tests account for gene correlation, typically through array permutation that by construction has proper Type I error control for the induced null. However, both Class 1 and Class 2 tests use a null hypothesis that all genes have the same degree of differential expression. We introduce a more sensible and general (Class 3) null under which the profile of differential expression is the same within the category and complement. Under this broader null, Class 2 tests are shown to be conservative. We propose standard bootstrap methods for testing against the Class 3 null and demonstrate they provide valid Type I error control and more power than array permutation in simulated datasets and real microarray experiments.

description: Η συγκεκριμένη μεταπτυχιακή εργασία επιδιώκει να ανιχνεύσει μορφές του μηδενισμού σε δύο συγγραφείς που είναι δεινοί παρατηρητές του φιλοσοφικού αυτού κινήματος, του Ντοστογιέφσκι και του Καζαντζάκη. Λόγω της πληθώρας των έργων που έχουν γράψει και οι δυο, εμείς εδώ περιοριζόμαστε στη συγκριτική μελέτη δύο μόνο έργων, του Εγκλήματος και Τιμωρίας από τη μια και του Βίου και πολιτείας του Αλέξη Ζορμπά από την άλλη. Στο πρώτο μέρος της εργασίας, καταπιανόμαστε με το θεωρητικό πλαίσιο του μηδενισμού, έτσι όπως ορίστηκε και μελετήθηκε συστηματικά από τον γερμανό φιλόσοφο Φρειδερίκο Νίτσε, ενώ στο δεύτερο, το λογοτεχνικό, θα δούμε αρχικά το γραμματολογικό και ιστορικό πλαίσιο των έργων και τη σχέση των συγγραφέων μεταξύ τους αλλά και τι τους συνδέει με τον ίδιο το Νίτσε. Θα παρακολουθήσουμε λοιπόν, ότι ο μηδενισμός εμφανίζεται σπερματικά στα δύο λογοτεχνικά έργα και πιο συγκεκριμένα μελετάμε τον τρόπο με τον οποίο οι λογοτεχνικοί ήρωες ενσαρκώνουν διάφορες μορφές του μηδενισμού, ποιοι χαρακτήρες είναι αυτοί και ποια είναι εκείνα τα ιδιαίτερα χαρακτηριστικά που τους καθιστούν μηδενιστές σε σχέση με τους υπόλοιπους ήρωες των έργων που δεν είναι.
description: The present dissertation aims to detect forms of nihilism in two writers who are excellent observers of this philosophical movement called nihilism, Dostoevsky and Kazantzakis. Because of their large amount of literary production, we’ ll study here comparatively only two of their works, Crime and Punishment and Life and Adventures of Alexis Zorbas At the first part of the dissertation we study nihilism, as it was defines and studied systematically by the German philosopher Friedrich Nietzsche, while at the second part, the literary one, we will see at first the historical framework of the literary works and more precisely, we study the way in which the heroes incarnate different forms of nihilism- which one of them are nihilists and why- what kind of characteristics they have that they make them nihilists.

description: Local magnetic fields in a molecule-based optically chiral magnet [Cr(CN)$_6$][Mn($S$)-pnH(H$_2$O)](H$_2$O) (GN-S) and its enantiomer (GN-R) are studied by means of muon spin rotation and relaxation (muSR). Detailed analysis of muon precession signals under zero field observed below T_c supports the average magnetic structure suggested by neutron powder diffraction. Moreover, comparison of muSR spectra between GN-S and GN-R suggests that they are a pair of complete optical isomers in terms of both crystallographic and magnetic structure. Possibility of magnetic chirality in such a pair is discussed.

description: Σκοπός της παρούσας μελετής ήταν η διεξοδική παρουσιάση του ζήτηματος των μισθών υπερημερίας, που υποχρεούται να καταβάλλει ο εργοδότης σε περίπτωση άκυρης απόλυσης, όπως αντιμετωπίζεται τόσο απο τη θεωρία, όσο και απο πληθώρα δικαστικών αποφάσεων. Στο πρώτο κεφάλαιο εξετάσαμε την υπερημερία του εργοδότη, την κατάσταση δηλαδή που περιέρχεται ο εργοδότης όταν προβαίνει σε άκυρη απόλυση της σύμβασης εργασίας του εργαζόμενου. Στο δεύτερο κεφάλαιο, παρουσιάστηκαν αναλυτικά ζητήματα ουσιαστικού δικαίου, όπως το περιεχόμενο των μισθών υπερημερίας, η αφαίρεση της ωφέλειας που απέκτησε ο μισθωτός κατά τη διάρκεια της υπερημερίας, ενώ μέσα απο μια κριτική επισκόπηση της νομολογίας θίξαμε και το ζήτημα της καταχρηστικής άσκησης της αξίωσης για μισθούς υπερημερίας. Τέλος στο τρίτο και τελευταίο κεφάλαιο ασχοληθήκαμε με ζητήματα δικονομικού δικαίου που αφορούν τους μισθούς υπερημερίας.
description: The aim of the present research was the detailed presentation of the issue of salaries overdue payments that is required to be paid by the employer in case of invalid dismissal, as seen from both the theory and exuberant judgments. In the first chapter we looked at the default of the employer , the status that accrues when the employer makes void dismissal of the employee's employment contract. The second chapter, presented detailed questions of substantive law, such as the content of salaries overdue payments, removal of the interest acquired by the employee during the period of delay and through a critical review of the case law we have raised the issue of improper exercise of claim for salaries overdue payments. Finally, the third and last chapter dealt with issues of procedural law on salaries overdue payments.
