description: In this work we report on observations with the Neutron Star Interior Composition Explorer of the known neutron star X-ray transient XTE J1739-285. We observed the source in 2020 February and March, finding it in a highly active bursting state. Across a 20-day period, we detected 32 thermonuclear X-ray bursts, with an average burst recurrence time of $2.0^{+0.4}_{-0.3}$ hr. A timing and spectral analysis of the ensemble of X-ray bursts reveals homogeneous burst properties, evidence for short-recurrence time bursts, and the detection of a 386.5 Hz burst oscillation candidate. The latter is especially notable, given that a previous study of this source claimed a 1122 Hz burst oscillation candidate. We did not find any evidence of variability near 1122 Hz, and instead find that the 386.5 Hz oscillation is the more prominent signal of the two burst oscillation candidates. Hence, we conclude it is unlikely that XTE J1739-285 has a sub-millisecond rotation period.

description: The form factor is an important tree shape index that facilitates the estimation of log volume of standing trees.In this project, a sample of 100 trees has been chosen with Systematic sampling, from Section 11 of the university’s forest of Taxiarhis, in order to find form factor equations for the Quercus frainetto trees of the section. The breast height diameter , the total height and the form factor of the trees of the sample, were measured. Thirty one equations were adjusted on the data using SPSS 14.0 .For each equation took place hypothesis testing and due to the fact that all the functions did not have the same dependent variable, Furnival’s quotient was used for their comparison. The analysis of the data gave the following equations: , coefficient of determination was 0,596, Farrar’s index FI was 0,629 , and the standard error of estimation was 0,08689, , coefficient of determination was 0,618 and the standard error of estimation was 0,03457, , coefficient of determination was 0,333 and the standard error of estimation was 0,04568 From the above functions the first gives the form factor according to the total height as well as the breast height diameter, the second one to the breast height diameter and the last one gives the form factor according to the total height.

description: We perform a feasibility study to search for axion-like particles (ALPs) using vector boson fusion (VBF) processes at the LHC. We work in an effective field theory framework with cutoff scale $Λ$ and ALP mass $m_{a}$, and assume that ALPs couple to photons with strength $\propto 1/Λ$. Assuming proton-proton collisions at $\sqrt{s} = 13$ TeV, we present the total VBF ALP production cross sections, ALP decay widths and lifetimes, and relevant kinematic distributions as a function of $m_{a}$ and $Λ$. We consider the $a\toγγ$ decay mode to show that the requirement of an energetic diphoton pair combined with two forward jets with large dijet mass and pseudorapidity separation can significantly reduce the Standard Model backgrounds, leading to a $5σ$ discovery reach for $10 \text{ MeV} \lesssim m_{a} \lesssim 1$ TeV with $Λ\lesssim 2$ TeV, assuming an integrated luminosity of 3000 fb$^{-1}$. In particular, this extends the LHC sensitivity to a previously unstudied region of the ALP parameter space.

Abstract
 Amisulpride intravenous (IV) injection (Barhemsys®; hereafter referred to as IV amisulpride), a selective dopamine receptor antagonist, is approved in the USA as a single IV infusion for the prevention and treatment of post-operative nausea and vomiting (PONV) in adults. Results from placebo-controlled phase III trials showed that IV amisulpride is efficacious both in the prevention of PONV (used either alone or in combination with an antiemetic of a different class) and in the treatment of PONV (irrespective of prior antiemetic prophylaxis status). When administered as a single IV infusion, amisulpride had a tolerability profile that was generally similar to that of placebo, with no significant safety concerns identified. Thus, IV amisulpride is a useful additional option in the prevention and treatment of PONV in adults, particularly for patients who have failed previous antiemetic prophylaxis and for whom effective treatment options may be limited.© Springer Nature Switzerland AG 2020

description: A three‐step modeling approach to obtain rheological properties from the kinetics of the metallocene‐catalyzed homopolymerization of ethene is developed. With that, linear as well as slightly branched high‐density polyethylene is investigated. Therefore, a deterministic kinetic model of the metallocene‐catalyzed polymerization of ethene is set up and coupled with a Monte Carlo algorithm to obtain molecular weight distributions and polymeric microstructures. The topological information is used as input for the rheology model to compute linear and non‐linear rheological properties.

description: Τα Κέντρα Εκπαίδευσης Ενηλίκων (ΚΕΕ) αποτελούν ένα νέο θεσμό στη χώρα μας στον τομέα της δια βίου μάθησης. Μέσω ευέλικτων προγραμμάτων και σε ένα ευρύ φάσμα θεματικών πεδίων, προσφέρουν εκπαιδευτικές ευκαιρίες σε όλους τους ενήλικες πολίτες της χώρας ώστε να αποκτούν νέες γνώσεις και δεξιότητες ή να αναβαθμίζουν τις υπάρχουσες, προκειμένου να ανταποκρίνονται στις ολοένα και αυξανόμενες απαιτήσεις της προσωπικής και εργασιακής τους ζωής, σε ένα συνεχώς μεταβαλλόμενο κοινωνικο - οικονομικό περιβάλλον. Στόχος της παρούσας εργασίας ήταν να διερευνήσει την επίδραση του φύλου στον προσδιορισμό των παραγόντων συμμετοχής σε προγράμματα των ΚΕΕ. Πιο συγκεκριμένα, το ενδιαφέρον εστιάστηκε στο αν οι άνδρες και οι γυναίκες προβάλλουν τους ίδιους λόγους συμμετοχής και προσδοκούν στα ίδια οφέλη από τη συμμετοχή τους στα προγράμματα μάθησης. Στο δείγμα περιελήφθησαν 100 ενήλικες (63 γυναίκες και 37 άνδρες) εκπαιδευόμενοι στο ΚΕΕ Καρδίτσας. Για τη διερεύνηση χρησιμοποιήθηκε ερωτηματολόγιο με κλειστές ερωτήσεις. Τα ευρήματα της μελέτης τα οποία προέκυψαν μετά από επεξεργασία με την κατασκευή διασταυρούμενων πινάκων και ταυτόχρονο έλεγχο με το στατιστικό κριτήριο χ2, έδειξαν ότι, το φύλο, σε αλληλεπίδραση με άλλες μεταβλητές, όπως, η εργασιακή κατάσταση, το επίπεδο εκπαίδευσης, η οικογενειακή κατάσταση και η ύπαρξη ή μη παιδιών, επιδρά στα κίνητρα και στις προσδοκίες συμμετοχής των ενηλίκων του δείγματος στα προγράμματα του ΚΕΕ Καρδίτσας.
description: Adult Learning Centers (ALCs) comprise a new institution in our country in the field of life-long learning. Through flexible courses and a wide range of subjects ALCs offer educational opportunities to all adults of the country and enable them to acquire new knowledge and skills or to upgrade the existing ones in order to live up to the increasing demands in their personal and professional life in an ever changing socio-economic environment.The aim of this thesis is to investigate how gender effects the participation factors in the courses of ALCs. In particular, I focused on the question whether men and women state the same reasons for participation and whether they expect the same benefits by participating in these courses. The sample includes 100 adults (67 women and 37 men) who have been trained in the ALC of Karditsa. A closed-type questionnaire has been used for the research.The results of the study which were obtained by simultaneously applying cross-tables and statistical criterion x2 showed that gender in combination with factors such as work position, formal training, marital status and presence/ absence of children in the family effect the participation of the sample mentioned above.

description: A sum rule relating the ratio $R_c = 2 Γ(B^+ \to K^+ π^0)/Γ(B^+ \to K^0 π^+)$ and the CP asymmetry $A_{CP}(B^+ \to K^+π^0)$ is proved to first order in the ratio of tree to penguin amplitudes. The sum rule explains why it is possible to have $R_c$ consistent with 1 together with a small CP asymmetry in $B^+ \to K^+ π^0$. The measured ratio $A_{CP}(B^+\to K^+π^0)/A_{CP}(B^0\to K^+π^-)$ rules out a small strong phase difference between a color-suppressed and a color-favored tree amplitude contributing to $B^+\to K^+π^0$ as favored by QCD factorization.

Transculturality in Sicilian Crime Fiction: The Case of Camilleri and Piazzese
Creators: name: Pezzotti, Barbara
Publisher: name: Scritture migranti
Year: 2022

description: Due to its very nature, crime fiction as a genre lends itself to representing conflicts, asymmetrical relations of power, crisis and violence (Anderson et al. 2012). However, a recent and successful wave of crime fiction has increasingly shifted from an orientalised gaze towards the ‘foreign’ to a transcultural representation of migrant communities that populate the urban landscape. This article concentrates on Andrea Camilleri’s Il cane di terracotta (1996, translated as The Terracotta Dog, 2004) and Il ladro di merendine (1996, translated as The Snack Thief, 2003), and Santo Piazzese’s I delitti di via Medina-Sidonia (1996). It shows that with their reference to a common Mediterranean culture and history (and the concept of homecoming as a counter-narrative for the present anti-immigration rhetoric), these three crime novels shape a transcultural space “hung in the balance between conflict, coexistence, and contaminations” (Cassano 2012, xxxiii) where human beings adapt to each other. Reading these novels through the concept of transculturality as well as Bhabha’s “third space” (1994), helps us understand that these novels are representative of a crime fiction that epitomizes the “uprooted geography” (Chambers 2008) of Mediterranean hybridity. Finally, they are a powerful example of the “re-emergence of the Mediterranean as a transnational region” (Ben-Yehoyada 2017).

description: This paper is purely expositional. The statement of the Kuratowski graph planarity criterion is simple and well-known. However, its classical proof is not easy. In this paper we present the Makarychev proof (with further simplifications by Prasolov, Telishev, Zaslavski and the author) which is possibly the simplest. In the Rusian version before the proof we present all the necessary definitions, and afterwards we state some close results on graphs and more general spaces. The paper is accessible for students familiar with the notion of a graph, and could be an interesting easy reading for mature mathematicians.

Analysis of [pi]-type floating breakwater in oblique waves
Creators: name: Gesraha, Mohamed M. R.
Publisher: name: University of British Columbia
Year: 2009

description: The present study investigates the diffraction problem of waves interacting with a long rectangular breakwater with two side plates, for brevity it will be referred to as pi-type. The effect of the addition of two side-boards on the performance of a rectangular breakwater is the main aim of this study. The structure is assumed to be placed in water of uniform constant depth, and an eigenfunction expansion method was used in the solution. The fluid is assumed inviscid, and the flow irrotational, so that a velocity potential may be used to describe the flow. The exciting forces, added masses, damping coefficients, responses of the structure, and the transmission coefficient were all calculated for different cases and their results were analyzed. Different waves approaching the breakwater from any direction are considered. Comparisons between the present approach and different numerical solutions published previously were used to verify the developed numerical model. Other comparisons between the traditional rectangular breakwater and the proposed pi-type breakwater are also performed. The present solution proved to be a fast accurate method as compared to other methods. The present study showed that maximum wave forces and heave response occur for the normal wave incidence, but the surge and pitch responses are not maximum for normal waves and different directions then need to be considered. The proposed breakwater experiences lower exciting forces when compared to a rectangular one having the same under-tip clearance, thus savings of materials and cost are achieved by using this type, provided its good performance with respect to wave transmission is assumed. The numerical results showed good agreement with the measured transmission coefficient for both the fixed structure and freely floating structure cases.

description: This study falls within the scope of Derivational Morphology and attempts to approach the morphological and semantic formation of adnominal derivatives of the Cyprus dialect that end in -ούδα> -ούα> -ου. In order to discover the regularities that we believe characterize the forming of these derivatives we will use the theoretical model of D. Corbin (1987, 1991) as a basis. According to the fundamental principles of this model, both the anticipated meaning and subjective morphological structure of derivatives are created with the Word Formation Rule so that their meaning is synthetic in relation to their structure. More particularly, the adnominal derivatives in -ούδα> -ούα> -ου are products of the evaluative WFR.

description: We study a contact process on a two-dimensional square lattice which is diluted by randomly removing bonds with probability p. For p<1/2 and varying birth rate $λ$ the model was shown to exhibit a continuous phase transition which belongs to the universality class of strongly disordered directed percolation. The phase transition line terminates in a multicritical point at p=1/2 and $λ=λ*=3.55(1)$, where the model can be interpreted as a critical directed percolation process running on a critical isotropic percolation cluster. In the present work we study the multicritical point and its neighboorhood by numerical simulations, discussing possible scaling forms which could describe the critical behavior at the transition.

description: In animal communication research, there is a keen interest in assessing and comparing the efficiency of communication systems with human languages. Yet, the gestural communication of our closest relatives, chimpanzees, remains underexplored. This thesis addresses this gap by investigating communicative efficiency in gestural communication across three chimpanzee communities: Sonso and Waibira in East Africa (Uganda) and Bossou in West Africa (Guinea). Employing a novel coding scheme and diverse gesture duration metrics, I examine the presence of Zipf's law of brevity and Menzerath's law, commonly expressed principles of communicative efficiency in human language, in chimpanzee gesturing. In addition, I directly assess the optimality of chimpanzee gestures using a novel linguistic metric from human language comparisons. I explore variations in gesture durations and sequence usage based on individual and social characteristics, such as familiarity, gender, age, and rank. Across these measures, a clear pattern emerges: Each chimpanzee community exhibits a distinct communicative style closely tied to their socio-ecological context. Remarkably, gestures in Bossou, the most cohesive community, demonstrate the first confirmed presence of Zipf's law of brevity and Menzerath's law, along with gesture repertoire optimisation reaching the lower bound of the distribution represented in human languages. Conversely, Waibira, the largest but least cohesive community, employs gestures with redundancy, favouring short sequences and lengthy single gestures. Sonso falls between these extremes, both in community dynamics and communicative efficiency. A consistent finding is that, as familiarity increases, gesture durations also lengthen, suggesting closer social connections lead to reduced pressure to communicate quickly or efficiently. Ultimately, each community employs a different communication style, highlighting the flexible potential of chimpanzee gestures.

description: In this work, we explore the connection between the critical curves ("shadows") and the quasinormal mode frequencies (in the eikonal limit) of Kerr black holes. This mapping has been previously established for non-rotating black holes. We show that, the shadow seen by an distant observer at a given inclination angle, can be mapped to a family of quasinormal modes with $m/(\ell+1/2)$ bounded within certain range, where $m$ is is azimuthal node number and $\ell$ is the angular node number. We discuss the possibility of testing such relation with space-borne gravitational wave detectors and the next-generation Event Horizon Telescope.

Subjects: subject: 660

description: Soluble, amorphous powders were prepared as precursors for the sol-gel processing of TiO2 films. Layers of up to 800 nm and 2.0 μm were prepared on borosilicate glass and Ni-alloy by multiple coating, respectively. Α refractive index of 2.3 was achieved. The interdependency of parameters such as solvent composition, withdrawal rate, thermal treatment with film quality, thickness and optical properties was investigated. The conditions were optimized for large-area coatings on an industrial scale. The overall process is highly advantageous for industrial production of optical interference filters due to the long-time stability of precursor powders and sols, high optical quality of the resulting films, excellent substrate adhesion and good compatibility with other sol-gel films.
Analytic calculations of the spectra of ultra-high energy cosmic ray nuclei. I. The case of CMB radiation

description: We present a systematic study of different methods for the analytic calculation of ultra-high energy nuclei diffuse spectra. Nuclei propagating in the intergalactic space are photo-disintegrated and decrease their Lorentz factor due to the interaction with cosmic microwave background and extragalactic background light. We calculate the evolution trajectories in the backward time, that describe how atomic mass number $A$ and Lorentz factor $Γ$ change with redshift $z$. Three methods of spectra calculations are investigated and compared: {\it (i)} trajectory method, {\it(ii)} kinetic equation combined with trajectory calculations and {\it (iii)} coupled kinetic equations. We believe that these three methods exhaust at least the principal possibilities for any analytic solution of the problem. In the most straightforward method {\it(i)} only trajectory calculations are used to connect the observed nuclei flux with the production rate of primary (accelerated) nuclei $A_0$. In the second method {\it (ii)} the flux (space density) of primary nuclei, and secondary nuclei and protons are calculated with the help of kinetic equation and trajectories are used only to determine the generation rates of these nuclei. The third method {\it (iii)} consists in solving the complete set of coupled kinetic equations, written starting with primary nuclei $A_0$, then for $A_0-1$ etc down to the $A$ of interest. The solution of the preceding equation gives the generation rate for the one which follows. An important element of the calculations for all methods is the systematic use of Lorentz factor instead of energy. We consider here the interaction of nuclei only with the cosmic microwave background, this case is particularly suitable for understanding the physical results.

description: One of today's leading packaging concepts in microelectronics and microsystems is the technology of Low Temperature Cofiring Ceramics (LTCC). It is based on ceramic tapes that sinter at low temperatures (< 950 °C) and are capable of fine-line wiring by use of high-conductivity metals, preferably silver ( ϑm = 961 °C). To lower sintering temperatures of crystalline powders, glass powder is added. Depending on the amount of glass added, two mechanisms of sintering are possible: reactive or nonreactive liquid phase sintering. Reactive sintering requires small amounts (< 10 vol.%) of a very low softening glass (ϑsoft < 400°C). If the glass amount is increased to more than 50 vol.%, nonreactive sintering occurs in the glass softening range. According to the microstructure observed for each case, the respective types of materials are called Glass Bonded Ceramics (GBC) and Glass Ceramic Composites (GCC). Integration of microwave filters in LTCC multilayers requires inner dielectric layers with medium, temperature-stable permittivities (εr = 30 to 60) and low dielectric loss (tan δ < 2 ∙ 10^-3). Up to now, appropriate materials have been realized only by GBC sintering at 900 °C and above. Hence, pure silver metallization is not possible. To overcome this limitation, GCC are a promising way. Therefore, crystalline substances possessing εr of about 100 and low dielectric loss - for example Ba(La, Nd)2Ti4O12 - were combined with special high-permittivity glasses. Α development of such glasses is presented in this work. Addition of oxides of easily polarizable elements (e. g. Nb2O5, La2O3 , TiO2 ) effects an increase in permittivity of selected basis compositions from the systems BaO-Al2O3-B2O3-SiO2 (εr up to 15) and La2O3-Ba2O3-TiO2 (εr up to 20). GCC mixtures made of 65 vol.% of these glasses and 35 vol.% BaLa2Ti4O12 showing microwave properties and sintering temperatures below 900 °C are introduced.

description: A calculation model of the bubble concentration field inside a melting space is presented, based on the technique of tracing representative bubbles. The bubbles in the model originated from glass batch and from refractory. The appropriate bubble input values were obtained by laboratory experiments. The impact of various initial and boundary conditions, as well as melting conditions, on the bubble distribution inside the melting space was studied: a) the impact if initial amount of entering bubbles and their size distribution, b) the impact of initial redox state of glass, and c) the influence of bubble history. The results demonstrated the significance of the redox state of glass and the average temperature along bubble trajectories for the fining process. The calculated bubble compositions at the output and bubble histories were used to distinguish the bubbles coming from two bubble sources and to reveal the starting positions of defect bubbles. An attempt was made to estimate the bubble impact on the glass flow and on the redox state of glass using the bubble tracing technique. The preliminary calculations indicated that bubbles influence the melt flow.

description: Understanding and controlling the transport properties of interacting fermions is a key forefront in quantum physics across a variety of experimental platforms. Motivated by recent experiments in 1D electron channels written on the $\mathrm{LaAlO_3}$/$\mathrm{SrTiO_3}$ interface, we analyse how the presence of different forms of spin-orbit coupling (SOC) can enhance electron pairing in 1D waveguides. We first show how the intrinsic Rashba SOC felt by electrons at interfaces such as $\mathrm{LaAlO_3}$/$\mathrm{SrTiO_3}$ can be reduced when they are confined in 1D. Then, we discuss how SOC can be engineered, and show using a mean-field Hartree-Fock-Bogoliubov model that SOC can generate and enhance spin-singlet and triplet electron pairing. Our results are consistent with two recent sets of experiments [Briggeman et al., arXiv:1912.07164; Sci. Adv. 6, eaba6337 (2020)] that are believed to engineer the forms of SOC investigated in this work, which suggests that metal-oxide heterostructures constitute attractive platforms to control the collective spin of electron bound states. However, our findings could also be applied to other experimental platforms involving spinful fermions with attractive interactions, such as cold atoms.

description: Dynamical properties of an impurity spin coupled symmetrically to sublattices of ordered 2D Heisenberg quantum antiferromagnet (i.e., frustrated impurity spin) are discussed at $T\ge0$ (existence of a small interaction stabilizing the long range order at $T\ne0$ is implied). We continue our study on this subject started in Phys.Rev.B 72, 174419 (2005), where spin-1/2 defect is discussed and the host spins fluctuations are considered within the spin-wave approximation (SWA). In the present paper we i) go beyond SWA and ii) study impurities with spins $S\ge1/2$. It is demonstrated that in contrast to defects coupled to sublattices asymmetrically longitudinal host spins fluctuations play important role in the frustrated impurity dynamics. The spectral function, that is proportional to $ω^2$ within SWA, acquires new terms proportional to $ω^2$ and $ωT^2$. It is observed that the spin-1/2 impurity susceptibility has the same structure as that obtained within SWA: the Lorenz peak and the non-resonant term. The difference is that the width of the peak becomes larger being proportional to $f^2(T/J)^3$ rather than $f^4(T/J)^3$, where $f$ is the dimensionless coupling parameter. We show that transverse static susceptibility acquires a new negative logarithmic contribution. In accordance with previous works we find that host spins fluctuations lead to an effective one-ion anisotropy on the impurity site. Then defects with $S>1/2$ appears to be split. We observe strong reduction of the value of the splitting due to longitudinal host spins fluctuations. We demonstrate that the dynamical impurity susceptibility contains $2S$ Lorenz peaks corresponding to transitions between the levels, and the non-resonant term.

description: Prediction of glass quality is a main objective of glass furnace modeling. Minimum residence time (MRT) counts among the crucial parameters for representing glass quality. Numerical simulation is an efficient tool for estimating this parameter. For a Round Robin a simple case had been chosen with a parallepiped-shaped glass tank to test the performance of numerical codes and their application in glass melting simulation. It was shown that the numerical discretization fixed by the participants is sufficient to represent the temperature and velocity fields. However, significant differences in the calculation of the MRT (6.2 to 7.8 h) between the different participants of the Round Robin were noticed. In this work it is shown that the grid resolution and the number of tracer particles have to be increased at certain locations to capture correctly the shortest path-time trajectory. The final value of 5.5 h for the MRT does not significantly change with further refinement of the grid and of trajectory calculation. The two principal methods known for the calculation of massless virtual particle trajectories are numerical tracing and flow-field stream lines. One established method to check the reliability of stream line calculations is the successive refinement of the numerical resolution. However, for large glass tanks, this method can be quite tedious or even unfeasible. Simplified methods are proposed to check the reliability of MRT calculation.

description: Das Verhältnis von Literatur und Gesellschaft lässt sich an Wilhelm Raabes spätem Text ‚Pfisters Mühle‘ als textexterner Antrieb und als textinternes Strukturmoment aufzeigen. Die Frage nach der poetologischen Relevanz des Textes wird textintern aufgegriffen, indem die Kopplung von Frage und potentiellen Antworten durch einen narrativ inszenierten Bilddiskurs dargestellt wird. Dieser Bilddiskurs bildet die Folie für eine narrative Selbstreflexion, anhand derer sich die Zeitlosigkeit und Aktualisierbarkeit des Textes zeigt. ‚Pfisters Mühle kann als eine Form von poetologischer Reflexion verstanden werden, da der Text erzählend dem Erzählen auf den Grund geht und zugleich Narration und Metanarration ist. Gleichzeitig wird auf die Unmöglichkeit eines abschließenden Metadiskurses verwiesen.
Application of electrical heating in forehearth channels

description: Electrical heating of forehearth channels can be either indirect with radiant heating elements installed above the glass surface, or direct utilizing immersed electrodes. Two types of heating elements are used, made of either silicon carbide or molybdenum disilicide. Electrodes are normally made of molybdenum, but tin oxide is also used, and platinum alloy may be required for some special applications. Direct electrical heating is also used in forehearths to supplement the traditional gas heating, and can provide a significant improvement in the thermal homogeneity of the glass at the end of the channel. Excellent results can also be obtained with full electrical heating. Whatever type of electrical heating is used, the relevant safety standards must be applied.

description: Terrestrial extrasolar planets around low-mass stars are prime targets when searching for atmospheric biosignatures with current and near-future telescopes. The habitable-zone Super-Earth LHS 1140 b could hold a hydrogen-dominated atmosphere and is an excellent candidate for detecting atmospheric features. In this study, we investigate how the instellation and planetary parameters influence the atmospheric climate, chemistry, and spectral appearance of LHS 1140 b. We study the detectability of selected molecules, in particular potential biosignatures, with the upcoming James Webb Space Telescope (JWST) and Extremely Large Telescope (ELT). In a first step we use the coupled climate-chemistry model, 1D-TERRA, to simulate a range of assumed atmospheric chemical compositions dominated by H$_2$ and CO$_2$. Further, we vary the concentrations of CH$_4$ by several orders of magnitude. In a second step we calculate transmission spectra of the simulated atmospheres and compare them to recent transit observations. Finally, we determine the observation time required to detect spectral bands with low resolution spectroscopy using JWST and the cross-correlation technique using ELT. In H$_2$-dominated and CH$_4$-rich atmospheres O$_2$ has strong chemical sinks, leading to low concentrations of O$_2$ and O$_3$. The potential biosignatures NH$_3$, PH$_3$, CH$_3$Cl and N$_2$O are less sensitive to the concentration of H$_2$, CO$_2$ and CH$_4$ in the atmosphere. In the simulated H$_2$-dominated atmosphere the detection of these gases might be feasible within 20 to 100 observation hours with ELT or JWST, when assuming weak extinction by hazes. If further observations of LHS 1140 b suggest a thin, clear, hydrogen-dominated atmosphere, the planet would be one of the best known targets to detect biosignature gases in the atmosphere of a habitable-zone rocky exoplanet with upcoming telescopes.

description: The demand for electricity and the need to replace fossil fuels by renewables have been growing steadily, and this transition will have significant implications to our world that are only beginning to be understood. Brazil is one important example of a big economy where the electricity is already supplied by renewables, such as hydro, wind and biomass-fired thermal power. In this work we investigated the electricity load curves in the last 20 years in Brazil, and four different scenarios for 2030 are proposed in order to evaluate the impact of increasing renewables in the national grid, at an hourly basis. The analysis shows that growing electricity demand and the expected reduction in the hydropower share will significantly increase the reliability of the national grid, due to higher peak load and also due to the intermittency of Solar and Wind. Without any gigawatt scale hydropower projected for the near future, increasing the share of these renewables should push hydropower to operate hundreds of hours every year above typical peak power levels experienced in the past. In order to avoid or reduce the threat related to this trend one of our scenarios suggests that solar water heaters could be massively deployed in Brazil, what would positively impact the system reliability by reducing the electricity demand mostly at peak loads during early evenings.
