description: We consider a non-chiral Luttinger liquid in the presence of a backscattering Hamiltonian which has an extended range. Right/left moving fermions at a given location can thus be converted as left/right moving fermions at a different location, within a specific range. We perform a momentum shell renormalization group treatment which gives the evolution of the relative degrees of freedom of this Hamiltonian contribution under the renormalization flow, and we study a few realistic examples of this extended backscattering Hamiltonian. We find that, for repulsive Coulomb interaction in the Luttinger liquid, any such Hamiltonian contribution evolves into a delta-like scalar potential upon renormalization to a zero temperature cutoff. On the opposite, for attractive couplings, the amplitude of this kinetic Hamiltonian is suppressed, rendering the junction fully transparent. As the renormalization procedure may have to be stopped because of experimental constraints such as finite temperature, we predict the actual spatial shape of the kinetic Hamiltonian at different stages of the renormalization procedure, as a function of the position and the Luttinger interaction parameter, and show that it undergoes structural changes. This renormalized kinetic Hamiltonian has thus to be used as an input for the perturbative calculation of the current, for which we provide analytic expressions in imaginary time. We discuss the experimental relevance of this work by looking at one-dimensional systems consisting of carbon nanotubes or semiconductor nanowires.

description: In this paper we study an archetypical scenario in which repulsive Casimir-Polder forces between an atom or molecule and two macroscopic bodies can be achieved. This is an extension of previous studies of the interaction between a polarizable atom and a wedge, in which repulsion occurs if the atom is sufficiently anisotropic and close enough to the symmetry plane of the wedge. A similar repulsion occurs if such an atom passes a thin cylinder or a wire. An obvious extension is to compute the interaction between such an atom and two facing wedges, which includes as a special case the interaction of an atom with a conducting screen possessing a slit, or between two parallel wires. To this end we further extend the electromagnetic multiple-scattering formalism for three-body interactions. To test this machinery we reinvestigate the interaction of a polarizable atom between two parallel conducting plates. In that case, three-body effects are shown to be small, and are dominated by three- and four-scattering terms. The atom-wedge calculation is illustrated by an analogous scalar situation, described in the Appendix. The wedge-wedge-atom geometry is difficult to analyze because this is a scale-free problem. But it is not so hard to investigate the three-body corrections to the interaction between an anisotropic atom or nanoparticle and a pair of parallel conducting cylinders, and show that the three-body effects are very small and do not affect the Casimir-Polder repulsion at large distances between the cylinders. Finally, we consider whether such highly anisotropic atoms needed for repulsion are practically realizable. Since this appears rather difficult to accomplish, it may be more feasible to observe such effects with highly anisotropic nano particles.

description: In the judgment Bouyid v. Belgium recently delivered by European Court of Human Rights, the Grand Chamber considers a single slap inflicted on a juvenile and an adult in police custody in breach of Article 3 ECHR. The Court ruling is an opportunity to consider the notion of “degrading treatment” and the strong link between this prohibition and the role of human dignity. Furthermore, the reasoning take position on the meaning of Article 3, which is an absolute right admitting of no derogation or exception.

description: The focus of this paper is to study the usage of social networking sites by the Karnatakites for finding information regarding COVID-19. A web survey was distributed among the targeted participants to collect data for the study. The study findings reported that cent percent of the participants were users of social networking sites in whichWhatsApp, YouTube, and Facebook were the most used SNSs for finding information regarding the COVID-19. The respondents used SNSs mainly to search for information regarding the status of COVID-19 in India as well as at the global level. Most of the respondents (48.8%) agreed that the information available on SNSs regarding COVID-19was informative and up to date. The study also reported that the majority of respondents found the use of social networking sites satisfiable in finding vital information regarding the COVID-19 pandemic. The study is first of its kind to explore the use of SNSs among the Karnatakites for finding information regarding the COVID-19 outbreak. The findings of the study, of course, give proper insights to the digital natives and netizens for using SNSs as information resources, especially during such critical pandemic disease outbreaks.

description: Summary. Interleukin-6 (IL-6) is a pleiotropic cytokine with pro-inflammatory and anti-inflammatory functions. Placentation and pregnancy progression depend on adequate interaction between the processes of proliferation, apoptosis, and invasion of trophoblast cells into the endometrium. Various cytokines and growth factors play important roles in regulating these processes, where IL-6 represents one of the major regulatory molecules influencing the trophoblast phenotype. In physiological circumstances, IL-6 is involved in angiogenesis and remodeling of endometrial blood flow, stimulates the production of placental hormones, and is one of the main regulators of inflammation response and immune homeostasis in the placenta. Elevated levels of IL-6 are indicated in women with infertility, preeclampsia, and placental neoplastic processes. Hypoxic conditions in the placenta play a pivotal role in modulating differentiation, invasion, and redox homeostasis of trophoblast and also seems to have a significant contribution to IL-6 effects. At the same time, IL-6 affects the oxidative state of trophoblasts, although the mechanisms of these outcomes are yet to be fully understood. Our experiments suggest the importance of hypoxic conditions in determining the effects of IL-6 in trophoblasts and the differential reactivity of JEG-3 cells in response to this cytokine. Additionally, increased levels of IL-6 in different systemic pathological states induce various disturbances of trophoblast cell homeostasis and could be one of the risk factors in the development of pregnancy disorders. Recently, increased IL-6 levels have been detected in COVID-19 cases as one of the major actors of the cytokine storm, raising the concerns of infection regarding the effects on the placenta and the offspring.

description: Improvements in the number of confirmed planets and the precision of observations imply a need to better understand subtle effects that may bias interpretations of exoplanet observations. One such effect is the distortion of a short period planet by its host star, affecting its derived density. We extend the work of Burton et al., Correia, and others, using a gravitational potential formulation to a sample of nearly 200 planets with periods less than 3 days. We find five planets exhibiting density variations of >10% and as many as 20 planets with deviations >5%. We derive an analytic approximation for this deviation as a function of the orbital period, transit depth, and mass ratio between the planet and host star, allowing for rapid determination of such tidal effects. We find that current density error bars are typically larger than tidal deviations but that reducing the uncertainty on transit depth and radial velocity (RV) amplitude by a factor of 3 causes tidal effects to dominate density errors (>50%) in >40% of planets in our sample, implying that in the near future upgraded observational precision will cause shape deviations to become a bottleneck with regards to analysis of exoplanet compositions. These two parameters are found to dominate uncertainties compared to errors on stellar mass and radius. We identify a group of eight planets (including WASP-19 b, HAT-P-7 b, and WASP-12 b) for which current density uncertainties are as much as 4x smaller than the potential shift due to tides, implying a possible 4σ bias on their density estimates.

description: Without any modification or post-treatment, superhydrophobic surfaces with good stability were fabricated by hot-embossing honeycomb patterns on Pd 40Cu 30Ni 10P 20 bulk metallic glass (BMG). The water contact angle reaches above 150° when the pitch between adjacent cells is larger than the critical size of 115.5 μm. The wetting behavior on the patterned BMG can be well rationalized in terms of the modified Cassie-Baxter theory [A. B. D. Cassie and S. Baxter, Trans. Faraday Soc. 40, 546 (1944)] by considering surface energy gradient. The achievement of the superhydrophobicity on BMG surface opens a window for the functional applications of metallic glasses.

description: We investigated a semi-analytic and numerical model to study the geometrically thin and optically thick accretion disk around Maclaurin spheroid (MS). The main interest is in the inner region of the so called α-disk, α being the viscosity parameter. Analytical calculations are done assuming radiation pressure and gas pressure dominated for close to Eddington mass accretion rate and $\dot{M}\lesssim 0.1\dot{M_{Edd}}$ respectively. We found that the change in eccentricity of MS gives a change at high frequency region in the emitted spectra. We found that disk parameters are dependent on eccentricity of MS. Our semi-analytic results show that qualitatively an increase in eccentricity of MS has same behavior as decrease in mass accretion rate. Numerical work has been carried out to see the viscous time evolution of the accretion disk around MS. In numerical model we showed that if the eccentricity of the object is high the matter will diffuse slowly during its viscous evolution. This gives a clue that how spin-up or spin-down can change the time evolution of the accretion disk using a simple Newtonian approach. The change in spectra can be used to determine the eccentricity of MS and thus period of the MS.

description: Quadrupolar spin-lattice relaxation effect was used to study the temperature dependence of the correlation of electric field gradient (EFG) observed by Cu63 and Cu65 NMR in the liquid and supercooled liquid states of Pd43 Cu27 Ni10 P20 metallic glass forming system. The correlation time of EFG was shown to have a dramatic temperature dependence that cannot be accounted for by available theory. Analyzed in the context of mode coupling theory (MCT), it is shown that the correlation time of EFG follows the scaling equation of MCT and reveals a Tc, the critical temperature of MCT, at 700 K. Other NMR techniques such as chemical exchange line narrowing and stimulated echo pulse sequences were used to study motion of P31 at lower temperatures. Combined together, these techniques cover the whole range of liquid to solid transition. By comparing the NMR results with data obtained by other techniques, a decoupling of motion for different types of atoms is revealed starting from Tc and below. This essentially demonstrates a transition from liquidlike to solidlike motion at Tc as predicted by MCT.

description: When a vortex beam with the spiral phase structure passes through a dynamic angular double slits (ADS), the interference pattern changes alternatively between destructive and constructive at the angular bisector direction of the ADS due to their phase difference. Based on this property, we experimentally demonstrate a simple method, which can precisely and efficiently determine the topological charge of vortex beams. What is more, this scheme allows determining both the modulus and sign of the topological charge of vortex beams simultaneously.

description: Dynamic crack propagation in a model brittle bulk metallic glass (BMG) is studied. Contrary to other brittle glassy materials, the authors find nanometer scale out-of-plane periodic corrugations along the crack surface of the BMG. The nanoscale periodicity remains nearly constant at different loading rates. An interpretation is presented to explain the evolution and the periodic coalescence of the nanometer scale cavities along the crack surface. The observation sheds light on the origin of dynamic fracture surface roughening in brittle materials and could be generally applicable to brittle materials.

Creators: name: Canotilho, Mariana
Publisher: name: Roma TrE-Press
Year: 2016

description: This paper analyses the relationship between austerity measures and constitutional law, focusing especially on the Portuguese example. The economic crisis and the adoption of the Memoranda of Understanding signed with EU institutions and the IMF in exchange for loans, has led to implement laws that were at the foundation of significant economic and social changes, in areas that include health, education, social security and protection of workers. Fundamental rights in these areas are part of the core of the social state under the Portuguese Constitution, which grants them a special and detailed protection.
The work focuses on the mechanisms of protection of fundamental rights, especially on the role of the Ombudsman and the Constitutional
Court. The latter has been the main ‘constitutional obstacle’ to the full implementation of austerity measures; however, and despite the accusation of political engagement or judicial activism, the constitutional jurisprudence during the crisis period was actually quite balanced, and based on fundamental principles rather than on social rights norms.

description: Adsorption isotherms of methane and ethane in single-walled carbon nanotubes (SWNTs) were measured by 1H nuclear magnetic resonance (NMR) at room temperature. It is shown that the interior of SWNTs becomes available for methane and ethane adsorption after cutting of SWNTs. Such endohedral adsorption dominates methane and ethane adsorption in SWNTs, at least below 1 MPa. The average exchange time between molecules adsorbed inside SWNTs and free gas molecules outside was estimated to be on the order of 80 ms. It is shown that exposure to oxygen has no effect on methane and ethane endohedral adsorption in SWNTs, suggesting that the adsorption energy of oxygen molecules inside SWNTs is small compared to that of methane. 13C NMR indicates that under atmospheric pressure and room temperature helium atoms could access the interstitial sites of SWNT bundles whereas H2, CO2, and N2 molecules could not.

This newest category of immigrants has specific characteristics compared to displacement of adults. Mainly, they are children who arrive to Spain without the company of their parents or legal guardian. After recognizing this situation, it is interesting to verify the national and international legal treatment granted, considering also the medical tests performed to verify age, resulting in one of the main problems affecting all their legal treatment.

Anisotropy of Cosmic Rays and Chaotic Trajectories in the Heliosphere

description: As cosmic rays (CRs) propagate in the Galaxy, they can be affected by magnetic structures that temporarily trap them and cause their trajectories to display chaotic behavior, therefore modifying the simple diffusion scenario. When CRs arrive at the Earth, they do so anisotropically. These chaotic effects can be a fundamental contributor to this anisotropy. Accordingly, this requires a comprehensive description of chaos in trapping conditions since assessing their repercussions on the CR arrival directions is necessary. This study utilizes a new method described in López-Barquero and Desiati (2021) to characterize chaotic trajectories in bound systems. This method is based on the Finite-Time Lyapunov Exponent (FTLE), a quantity that determines the levels of chaos based on the trajectories' divergence rate. The FTLE is useful since it adapts to trapping conditions in magnetic structures or even propagating media changes. Here, we explore the effects that chaos and trapping can have on the TeV CR anisotropy. Concretely, we apply this method to study the behavior of CRs entering the heliosphere. Specifically, how the distinct heliospheric structures and CR impinging directions from the ISM can affect chaos levels. The heliosphere has an intrinsic directionality that affects CRs differently depending on where they enter it. This feature causes preferential directions from which particles tend to be more chaotic than others. This eventually translates into changes in the arrival maps which are not uniformly distributed. Instead, we expect sectors in the map to change separately from others, creating a time variation that could be detected. Consequently, this result points to the idea that time-variability in the maps is essential to understanding the CR anisotropy's overall processes.

description: A large redshift of the photoluminescence (PL) peak energy is found in hydrogenated amorphous silicon films prepared by hot-wire chemical-vapor deposition with a high-growth rate ≥50 Å/s. The PL intensity is as high as that in the standard film and its temperature dependence shows thermalization behavior. The origin of the redshift is clarified by employing 1H nuclear magnetic resonance and mass density measurements. A ∼2% volume fraction of tube-like nanoscale voids is identified. The long spin-lattice relaxation time of H2 in the nanovoids implies a negligible density of silicon dangling bonds on the nanovoid surfaces. We suggest that highly strained bonds on these surfaces form broad conduction-band tail states that are responsible for the PL redshift.

description: We outline a paradigm to preserve results of digital scholarship, whether they are query results, feature values, or topic assignments. This paradigm is characterized by using annotations as multifunctional carriers and making them portable. The testing grounds we have chosen are two significant enterprises, one in the history of science, and one in Hebrew scholarship. The first one (CKCC) focuses on the results of a project where a Dutch consortium of universities, research institutes, and cultural heritage institutions experimented for 4 years with language techniques and topic modeling methods with the aim to analyze the emergence of scholarly debates. The data: a complex set of about 20.000 letters. The second one (DTHB) is a multi-year effort to express the linguistic features of the Hebrew bible in a text database, which is still growing in detail and sophistication. Versions of this database are packaged in commercial bible study software. We state that the results of these forms of scholarship require new knowledge management and archive practices. Only when researchers can build efficiently on each other's (intermediate) results, they can achieve the aggregations of quality data by which new questions can be answered, and hidden patterns visualized. Archives are required to find a balance between preserving authoritative versions of sources and supporting collaborative efforts in digital scholarship. Annotations are promising vehicles for preserving and reusing research results.

description: This study adopts a cross-linguistic perspective and investigates how musical expertise affects the perception of duration and pitch in language. Native Chinese (N=44) and Estonians (N=46), each group subdivided into musicians and non-musicians, participated in a mismatch negativity (MMN) experiment where they passively listened to both Chinese and Estonian stimuli, followed by an attentive behavioral experiment where they discriminated the stimuli in the non-native language (i.e., Chinese to Estonian participants and Estonian to Chinese participants). In both experiments, stimuli of duration change, pitch change, and duration plus pitch change were discriminated. We found higher behavioral sensitivity among Chinese musicians than non-musicians in perceiving the duration change in Estonian and higher behavioral sensitivity among Estonian musicians than non-musicians in perceiving all types of changes in Chinese, but no corresponding musicality effect was found in the MMN results, which suggests a more salient musicality effect on foreign language processing when attention is required. Secondly, Chinese musicians did not outperform non-musicians in attentively discriminating the pitch-related stimuli in Estonian, suggesting that musical expertise can be overridden by tonal language experience when perceiving foreign linguistic pitch, especially when an attentive discrimination task is administered. Thirdly, we found larger MMN among Chinese and Estonian musicians than their non-musician counterparts in perceiving the largest deviant (i.e., duration plus pitch) in their native language, demonstrating a positive musicality effect in native language processing.

description: In der vorliegenden Arbeit wird die Stabilität und Variabilität von mobilitätsbe-zogenem Alltagshandeln in einer interdisziplinären Perspektive betrachtet. Anstatt, wie in der Verkehrswissenschaft und modellierung üblich, die Aktivitä-ten der Verkehrsnachfrage als Ausgangspunkt zu nehmen, werden die sozialen Beziehungen der Menschen betrachtet, die diese Aktivitäten erst möglich bzw. erforderlich machen. In dieser Sichtweise werden Veränderungspotenziale und Beharrungsten-denzen nicht nur auf die Strukturen der gebauten Umwelt oder individuelle Präferenzstrukturen zurückgeführt bzw. durch diese erklärt, sondern es wird darüber hinaus die gesellschaftliche Dimension menschlicher Handlungen in den Blick genommen. Dafür wurde von September 2018 bis März 2019 eine qualitative soziale Netzwerkanalyse durchgeführt. Dabei handelt es sich um eine etablierte Me-thode der empirischen Sozialforschung, die sich besonders für die Erforschung sozialer Beziehungen anbietet. Um mobilitätsrelevante soziale Phänomene in möglichst unterschiedlichen Lebensbereichen in den Blick zu nehmen, wird hier unter einem sozialen Netzwerk ein Beziehungsgeflecht verstanden, welches individuelle, korporative und kollektive Akteure miteinander verbindet. In dieser Sichtweise pflegen Menschen soziale Beziehungen zu ihren Freunden und ihrer Familie, aber auch zu ihrem Sportverein oder einem Supermarkt. Als Ergebnis liefert die Arbeit tiefe Einblicke in die Merkmale verschiedener sozialer Beziehungen. Dabei werden insbesondere die Merkmale herausgear-beitet, die sich anbieten, um die Stabilität und Variabilität von Alltagshandeln und damit verbundener Zielwahlentscheidungen zu adressieren. Dies umfasst neben dem raum-zeitlichen Kontext auch Merkmale des emotiv-affektiven Kontextes, in den die Beziehungen eingebettet sind. Davon ausgehend wird eine Typologie präsentiert, die aufzeigt, dass Menschen ihre sozialen Netzwerke auf unterschiedliche Weise konfigurieren und dass sich je nach Konfiguration unterschiedliche Freiheitsgrade ergeben, um auf Anreize und Gelegenheiten der gebauten Umwelt zu reagieren. Die Typologie bietet damit eine Ergänzung zu der raumzentrierten Sichtweise der Verkehrsforschung und modellierung, indem sie die soziale Eingebundenheit anhand ausgewählter Repräsentanten. Darüber hinaus wird ein Weg aufgezeigt, wie soziale Beziehungen für die Verkehrsnachfragemodellierung nutzbar gemacht werden können. Dafür wird ein konzeptuelles Modell vorgestellt, welches die Aktivitäten und Zielwahl über eine dazwischenliegende Beziehungswahl miteinander verbindet. Im Mittel-punkt des Modells stehen die Bedingungen, unter denen damit zu rechnen ist, dass Menschen auf Grundlage eines Abwägungsprozesses entscheiden und wann davon auszugehen ist, dass sie stabilen Gewohnheiten folgen.

description: CsSnI3 is a promising eco-friendly solution for energy harvesting technologies. It exists at room temperature in either a black perovskite polymorph or a yellow 1D double-chain, which irreversibly deteriorates in the air. In this work, we unveil the relative thermodynamic stability between the two structures with a first-principles sampling of the CsSnI3 finite-temperature phase diagram, discovering how it is driven by anomalously large quantum and anharmonic ionic fluctuations. Thanks to a comprehensive treatment of anharmonicity, the simulations deliver a remarkable agreement with known experimental data for the transition temperatures of the orthorhombic, rhombohedral, and cubic perovskite structures and the thermal expansion coefficient. We disclose how the perovskite polymorphs are the ground state above \SI{270}{\kelvin} and discover an abnormal decrease in heat capacity upon heating in the cubic black perovskite. Our results also significantly downplay the Cs+ rattling modes' contribution to mechanical instability. The remarkable agreement with experiments validates our methodology, which can be systematically applied to all metal halides.

description: A recurrent debate in social sciences concerns the distinction between unsafety as an ʺobjectiveʺ status and unsafety as a ʺsubjective ʺ one. The latter is in turn generated by both inside (psychological) and outside (social and economic) drivers, politics and the media system being the leading actors. In order to clarify the paradoxes of unsafety (fear of negative events is not correlated to the extent of their effects nor to the probability of their occurence rather to the intentionality of the authors) we distinguish among dangers (a non intentional damage as a natural disaster), risks (an unexpected negative outcome of a positively oriented intention) and threats (an intentional damage caused by an enemy). The distinction is not an academic one as fas as it involves different approaches to security policies.

The half-century history of studies of Romano's star

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Luminous blue variables (LBVs) are rare objects of very high luminosity and mass loss rates, low wind velocities, exhibiting strong irregular photometric and spectral variability. They are generally believed to be a relatively short evolutionary stage in the life of a massive star, marking the transition from the Main Sequence toward Wolf-Rayet (WR) stars. However, recent studies indicate that progenitors of several supernovae underwent LBV-like eruptions. These studies support the view that at least some LBV stars are the end point of the evolution but not a transition phase. LBVs are rare objects, observations of whose in the Galaxy are inevitably connected with difficulties in determination of the distance and interstellar extinction. Hence, studying these rare objects in nearby galaxies is potentially more prospective. Therefore, investigation of the extragalactic star Romano's star (V532 or GR290) which is now classified as LBV/post-LBV star and shows late-WN spectrum, is very important for our understanding of evolution of massive stars in general.

description: We present a post-distortion linearization technique for a Semiconductor Optical Amplifier Mach-Zehnder Interferometer (SOA-MZI) photonic sampler. The sampling source is an active mode-locked laser producing 12.6 ps-width pulses with a repetition frequency of 10 GHz. The mathematical model for the linearization technique is presented, and then evaluated for the quasi-static regime, i.e. sampling continuous-wave signals, and for the dynamic regime, i.e. sampling sinusoidal signals. A significant improvement in terms of Total Harmonic Distortion (THD) equal to 23.4 dB is observed for a modulation index equal to 80% in the quasi-static regime, matching the highest observed THD improvement in the dynamic regime.

description: In the rapidly evolving landscape of health care, the security and management of patient data emerge as paramount concerns. Traditional centralized systems have shown vulnerabilities, leading to breaches and unauthorized access. This paper delves into the transformative potential of blockchain technology as a solution to these challenges. Blockchain, primarily recognized for its role in cryptocurrency, offers features such as decentralization, immutability, and transparency, making it a promising candidate for secure health care data management. Through an exploration of its fundamental principles and a comparative analysis of two case studies, the practical implementations and outcomes of blockchain in health care settings are highlighted. The findings suggest that while blockchain presents significant advantages, its integration into health care is accompanied by certain limitations and ethical considerations. As the health care industry stands on the cusp of a potential shift in data management, this paper provides insights, recommendations, and a vision for the future, emphasizing the promise and implications of blockchain technology.
Sunspot latitudes during the Maunder Minimum: a machine-readable catalogue from previous studies

description: The Maunder Minimum (1645-1715 approximately) was a period of very low solar activity and a strong hemispheric asymmetry, with most of sunspots in the southern hemisphere. In this paper, two data sets of sunspot latitudes during the Maunder minimum have been recovered for the international scientific community. The first data set is constituted by latitudes of sunspots appearing in the catalogue published by Gustav Spörer nearly 130 years ago. The second data set is based on the sunspot latitudes displayed in the butterfly diagram for the Maunder Minimum which was published by Ribes and Nesme-Ribes almost 20 years ago. We have calculated the asymmetry index using these data sets confirming a strong hemispherical asymmetry in this period. A machine-readable version of this catalogue with both data sets is available in the Historical Archive of Sunspot Observations (http://haso.unex.es) and in the appendix of this article.

title:  La Corte suprema del Regno Unito su revoca della cittadinanza e sicurezza nazionale: il caso Pham
Creators: name: Martino, Pamela
Publisher: name: Roma TrE-Press
Year: 2016

description: The comment regards the issues of statelessness and citizenship revocation as discussed by the British judges. In the case of Pham, the Supreme Court unanimously dismissed a suspected terrorist’s appeal which held that Pham was a Vietnamese national at the time the Home Secretary deprived him of his British citizenship. The key issue for the court was whether the British Nationality Act 1981 prevented the Home Secretary from depriving Pham of British citizenship because making an order of that nature would cause him to become stateless. In the Supreme Court, Pham argued that the deprivation decision was disproportionate and unlawful under EU law. However, the court did not find it necessary to resolve the dispute about EU law.
The judgment emphasizes the British Government’s powers to revoke the citizenship right to fight terrorism; however the Court defines a space of discussion about issues of EU law and its relation with domestic law by showing the increasing role of judges in the British form of government.

description: The nutritional and sensory characteristics of processed meat are of major concern to consumers across the globe. This study evaluated nutritional and sensory properties of pork sausages using pig stomach as filler meat. Pig stomach replaced lean pork at 0% (control), 25%, 50%, 75% and 100%, respectively to obtain treatments coded as T0, T25, T50, T75 and T100, respectively. The sausages were assessed for acidity, water holding capacity, cooking loss, proximate composition and sensory attributes. There were no significant differences (p>0.05) in flavour of sausages in particular; and all other sensory attributes of sausages produced with or without pig stomachs. Treatments T0, T25 and T50 were very similar in most of the sensory properties. Both pH and water holding capacity reduced with increasing levels of pig stomach used, and there were significant differences (p<0.05) between treatments. The results obtained suggest that pig stomach could be used at 50% in smoked pork sausages without adverse effects on nutritional and sensory properties.

description: Ground-based laser interferometers for gravitational-wave (GW) detection were first constructed starting 20 years ago and as of 2010 collection of several years' worth of science data at initial design sensitivities was completed. Upgrades to the initial detectors together with construction of brand new detectors are ongoing and feature advanced technologies to improve the sensitivity to GWs. This conference proceeding provides an overview of the common design features of ground-based laser interferometric GW detectors and establishes the context for the status updates of each of the four gravitational-wave detectors around the world: Advanced LIGO, Advanced Virgo, GEO600 and KAGRA.
