Euglycaemic diabetic ketoacidosis as complication of upper gastrointestinal bleed in a patient with underlying Type 2 diabetes
Creators: name: Abd Mokti, Abdullah Shamshir
Publisher: name: Zenodo
Year: 2021

description: INTRODUCTION Diabetic ketoacidosis (DKA) is one of the most serious complications of both type 1 and type 2 diabetes and is associated with high mortality between 1-5%. Euglycaemic DKA on the other hand is defined by Random Blood sugar (RBS) of more than 11 mmol/l with metabolic acidosis (pH < 7.35) and ketonaemia (>2) and few causes have been implicated; among them in Type 1 diabetes, pregnancy and resent use of SGLT-2 inhibitors in a diabetic patient. CASE DESCRIPTION We describe a case of a 69 year old gentleman with underlying Hypertension, Type 2 diabetes and chronic kidney disease stage 4. She presented with a week history of lethargy, black-tarry stool, poor oral intake and haematemesis for 1 day. On further questioning she has history of taking traditional medications. Examination reveals palor and mild epigastric tenderness, no stigmata of chronic liver disease, mildly dehydrated and insertion of nasogastric tube reveals coffee ground. Vital signs showed tachycardia (heart rate 120) but normotensive. Blood investigations reveal normochromic normocytic anaemia with Hb 4 and disproportionately increase in urea and creatinine (urea 18, cr 243) in keeping with diagnosis of upper gastro-intestinal bleed. Capillary blood glucose (CBG) 9 mmol/l and there was no acidosis on venous blood gas (VBG). She was kept nil-by-mouth, transfused 2 pints packed cell and infused with proton-pump-inhibitor while awaiting for gastroscopy. 6 hours into admission, she was noted to have heavy breathing and repeated blood investigation showed acidosis VBG: pH 7.21, HCO3 11 with CBG of 8mmol/l, lactate 1.2 .Serum ketone was high at 6 mmol/l. Diagnosis of euglycaemic DKA was made and she was treated with standard treatment of DKA with fluid resuscitation with normal saline, intravenous insulin and glucose infusion and 12 hours later, ketoacidosis resolved, PH 7.35, HCO3 25, Ketone 1.2. She proceeded with gastroscopy which revealed 2 Duodenal ulcer IIC LEARNING POINT and CONCLUSION This case illustrates the need to have high index of suspicion for diagnosis of euglycaemic diabetic ketoacidosis when a diabetic patient with multiple comorbidities such as chronic renal failure, upper gastro-intestinal bleed and starvation when acidosis is present even in the setting of a normal CBG. In conclusion, investigating for level of serum ketone in unexplained acidosis in patients with diabetes after excluding other causes could be the way forward to better recognise euglycaemic DKA and institute treatment appropriately.

description: The outstanding discrepancy between the measured and calculated (local-density approximation) Fermi surfaces in the well-characterized, paramagnetic Fermi liquid Sr2RhO4 is resolved by including the spin-orbit coupling and Coulomb repulsion. This results in an effective spin-orbit coupling constant enhanced 2.15 times over the bare value. A simple formalism allows discussion of other systems. For Sr2RhO4, the experimental specific-heat and mass enhancements are found to be 2.2.

description: Action detection plays an important role in high-level video understanding and media interpretation. Many existing studies fulfill this spatio-temporal localization by modeling the context, capturing the relationship of actors, objects, and scenes conveyed in the video. However, they often universally treat all the actors without considering the consistency and distinctness between individuals, leaving much room for improvement. In this paper, we explicitly highlight the identity information of the actors in terms of both long-term and short-term context through a graph memory network, namely identity-aware graph memory network (IGMN). Specifically, we propose the hierarchical graph neural network (HGNN) to comprehensively conduct long-term relation modeling within the same identity as well as between different ones. Regarding short-term context, we develop a dual attention module (DAM) to generate identity-aware constraint to reduce the influence of interference by the actors of different identities. Extensive experiments on the challenging AVA dataset demonstrate the effectiveness of our method, which achieves state-of-the-art results on AVA v2.1 and v2.2.

description: Highly dynamic environments, with moving objects such as cars or humans, can pose a performance challenge for LiDAR SLAM systems that assume largely static scenes. To overcome this challenge and support the deployment of robots in real world scenarios, we propose a complete solution for a dynamic object aware LiDAR SLAM algorithm. This is achieved by leveraging a real-time capable neural network that can detect dynamic objects, thus allowing our system to deal with them explicitly. To efficiently generate the necessary training data which is key to our approach, we present a novel end-to-end occupancy grid based pipeline that can automatically label a wide variety of arbitrary dynamic objects. Our solution can thus generalize to different environments without the need for expensive manual labeling and at the same time avoids assumptions about the presence of a predefined set of known objects in the scene. Using this technique, we automatically label over 12000 LiDAR scans collected in an urban environment with a large amount of pedestrians and use this data to train a neural network, achieving an average segmentation IoU of 0.82. We show that explicitly dealing with dynamic objects can improve the LiDAR SLAM odometry performance by 39.6% while yielding maps which better represent the environments. A supplementary video as well as our test data are available online.

description: App usage prediction is important for smartphone system optimization to enhance user experience. Existing modeling approaches utilize historical app usage logs along with a wide range of semantic information to predict the app usage; however, they are only effective in certain scenarios and cannot be generalized across different situations. This paper address this problem by developing a model called Contextual and Semantic Embedding model for App Usage Prediction (CoSEM) for app usage prediction that leverages integration of 1) semantic information embedding and 2) contextual information embedding based on historical app usage of individuals. Extensive experiments show that the combination of semantic information and history app usage information enables our model to outperform the baselines on three real-world datasets, achieving an MRR score over 0.55,0.57,0.86 and Hit rate scores of more than 0.71, 0.75, and 0.95, respectively.

description: We present Ha integral field spectroscopy of well resolved, UV/optically selected z~2 star-forming galaxies as part of the SINS survey with SINFONI on the ESO VLT. Our laser guide star adaptive optics and good seeing data show the presence of turbulent rotating star forming rings/disks, plus central bulge/inner disk components, whose mass fractions relative to total dynamical mass appears to scale with [NII]/Ha flux ratio and star formation age. We propose that the buildup of the central disks and bulges of massive galaxies at z~2 can be driven by the early secular evolution of gas-rich proto-disks. High redshift disks exhibit large random motions. This turbulence may in part be stirred up by the release of gravitational energy in the rapid cold accretion flows along the filaments of the cosmic web. As a result dynamical friction and viscous processes proceed on a time scale of <1 Gyr, at least an order of magnitude faster than in z~0 disk galaxies. Early secular evolution thus drives gas and stars into the central regions and can build up exponential disks and massive bulges, even without major mergers. Secular evolution along with increased efficiency of star formation at high surface densities may also help to account for the short time scales of the stellar buildup observed in massive galaxies at z~2.

Cold r-Process in Neutrino-Driven Winds

Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The r-process in a low temperature environment is explored, in which the neutron emission by photodisintegration does not play a role (cold r-process). A semi-analytic neutrino-driven wind model is utilized for this purpose. The temperature in a supersonically expanding outflow can quickly drop to a few 10^8 K, where the (n, gamma)-(gamma, n) equilibrium is never achieved during the heavy r-nuclei synthesis. In addition, the neutron capture competes with the beta-decay owing to the low matter density. Despite such non-standard physical conditions for the cold r-process, a solar-like r-process abundance curve can be reproduced. The cold r-process predicts, however, the low lead production compared to that expected in the traditional r-process conditions, which can be a possible explanation for the low lead abundances found in a couple of r-process-rich Galactic halo stars.

description: Deep Neck Space (DNS) infections are described as inflammation of the tissues with collection of abscess within potential fascial spaces in the head and neck region. Odontogenic infections can spread rapidly into deep neck and mediastinum area. In this case report, we are presenting a 30 years old Indonesian male that complained of pain over the right upper and lower wisdom teeth for the past two weeks. He has no known medical illness. A week later, he developed facial swelling at the right submandibular region which extended to the right neck and chest region. He presented with fever, experienced with odynophagia, therefore lead him to reduce in oral intake. However, due to poor economic status he did not seek for any treatment. As the condition of the patient progressively deteriorated, he attended to Emergency Department (ED) with septic look, necrosed right chest and strong foul smell. Almost 200 cubic centimeter of pus aspirated by ED team from the right neck punctum. This patient was then referred to multi-disciplinary team involving General Surgery, Otorhinolaryngology and Oral and Maxillofacial Surgery. Computerized tomography scan of head, neck and thorax reported with abscess collection involving right DNS, medialization of right pharyngeal wall that extended inferiorly towards right anterior thoracic wall. These strongly suggest to be associated with grossly decayed right upper and lower wisdom teeth. A diagnosis of necrotizing fasciitis at right chest secondary to odontogenic origin was made. Subsequently, emergency operation was commenced on the same day that involved wound debridement at right chest, incision and drainage at right neck and surgical removal of both wisdom teeth. Patient was also administered with systemic antibiotic. At day 10, he was discharged. A week later, patient showed marked improvement in the healing of intra-oral surgical site and right chest region. Conclusively, multi-disciplinary intervention with concurrent systemic antibiotic therapy significantly reduces morbidity and mortality rate in the management of DNS infections.

description: The evidence of culture’s impact on corruption and its consequences is still inconclusive despite several investigations: (1) Sometimes, theory is lacking and causes and consequences seem exchangeable. Based on psychological research on the distribution and use of power, we predicted that a steeper distribution of power induces more corruption and elaborated its negative consequences in a complex causal model. (2) For measuring power distribution, pervading national culture, we augmented Hofstede’s ‘Power Distance’ with three additional indicators into a reversed, more reliable and valid culture composite called “Power Balanced Freedom” (PBF). (3) Instead of the usual regression and instrument approaches, which cannot estimate multiple causal chains including causal feedback, a non-recursive path analysis was employed with data from 85 nations. PBF predicted less national Corruption (62%), with positive effects on Gross Domestic Product (GDP, 72%) and Inequality Adjusted Human Development (IHDI, 66%, including Life Expectancy, Income, and Education). The often expected reverse effect of GDP on Corruption was not significant. Contrary to influential authors from economics, culture variables are the most important predictors of corruption and its consequences. Nonetheless, our extended model supports the main thrust of their ideas and adds more precision. Our conceptual distinction of the uses of power and our empirical measure PBF reflect Kant’s ethical imperative: freedom and autonomy for everyone. Widely shared life chances as measured by IHDI reflect utilitarian, consequentialist ideas. These different ethical approaches are connected in the confirmed causal model, in line with Rawls’ first and second principle of justice.

description: A classical random walker starting on a node of a finite graph will always reach any other node since the search is ergodic, namely it is fully exploring space, hence the arrival probability is unity. For quantum walks, destructive interference may induce effectively non-ergodic features in such search processes. Under repeated projective local measurements, made on a target state, the final detection of the system is not guaranteed since the Hilbert space is split into a bright subspace and an orthogonal dark one. Using this we find an uncertainty relation for the deviations of the detection probability from its classical counterpart, in terms of the energy fluctuations.

description: INTRODUCTION There are several studies reported that there are increasing trends of refractive error over time. A study among Taiwanese School children has reported increasing trends of myopia in a 20 years period between 1983 and 2000. This study aims to describe the trends of refractive error among 7 years old patients Malay between 2012 and 2019. METHODS Record of eye assessment of seven years old Malay children attending optometrist clinic in 2012 and 2019 were obtained from electronic medical record. Subjects who had ocular co-morbidities were excluded from this study. 30 subjects for each year was selected using simple random sampling. Data of refractive error was derived from subjective refraction. Objective refraction was selected if patient reported as poor subjective response. All refractive status were recorded in spherical equivalent and were grouped either myopia (<-0.5D), emmetropia (-0.5 to +0.50D) and hyperopia (>+0.5D). Subject who astigmatism more than -0.50DC were recorded. The mean values for spherical equivalent of the refractive status on 2012 and 2019 were calculated. RESULTS & DISCUSSION The proportion of myopia was similar in 2012 and 2019 (56.6%) and hyperopia decreased from 16.6% to 10%. There were increasing trend in emmetropia (26.6% to 33.4%) and astigmatism (63.2% to 73.4%). Mean refractive error shifted from -0.32 D in 2012 to -0.90 D in 2019. CONCLUSION Our results show that the percentage of myopia remained high in both year and there are increasing of mean refractive error from 2012 to 2019. Our results stress the importance of early eye examinations and awareness among parent and teachers regarding vision problems in children. This study has some limitation which is, the data that we obtained from electronic medical record only available from 2012. The Covid 19 pandemic had give an impact to attendance of patients in 2020, thus we are unable to study differences of refractive error in a 10 years period.

description: We report on the UV laser induced fluorescence of hexagonal boron nitride (h-BN) following nanosecond laser irradiation of the surface under vacuum and in different environments of nitrogen gas and ambient air. The observed fluorescence bands are tentatively ascribed to impurity and mono (VN), or multiple (m-VN with m = 2 or 3) nitrogen vacancies. A structured fluorescence band between 300 nm and 350 nm is assigned to impurity-band transition and its complex lineshape is attributed to phonon replicas. An additional band at 340 nm, assigned to VN vacancies on surface, is observed under vacuum and quenched by adsorbed molecular oxygen. UV-irradiation of h-BN under vacuum results in a broad asymmetric fluorescence at ~400 nm assigned to m-VN vacancies; further irradiation breaks more B-N bonds enriching the surface with elemental boron. However, no boron deposit appears under irradiation of samples in ambient atmosphere. This effect is explained by oxygen healing of radiation-induced surface defects. Formation of the oxide layer prevents B-N dissociation and preserves the bulk sample stoichiometry.

description: Restoration of the electroweak symmetry at temperatures around the Higgs mass is linked to tight phenomenological constraints on many baryogenesis scenarios. A potential remedy can be found in mechanisms of electroweak symmetry non-restoration (SNR), in which symmetry breaking is extended to higher temperatures due to new states with couplings to the Standard Model. Here we show that, in the presence of a second Higgs doublet, SNR can be realized with only a handful of new fermions which can be identified as viable dark matter candidates consistent with all current observational constraints. The competing requirements on this class of models allow for SNR at temperatures up to $\sim$TeV, and imply the presence of sub-TeV new physics with sizable interactions with the Standard Model. As a result this scenario is highly testable with signals in reach of next-generation collider and dark matter direct detection experiments.

description: The Extreme ultraviolet Imaging Spectrometer (EIS) on board Hinode is the first solar telescope to obtain wide slit spectral images that can be used for detecting Doppler flows in transition region and coronal lines on the Sun and to relate them to their surrounding small scale dynamics. We select EIS lines covering the temperature range 6x10^4 K to 2x10^6 K that give spectrally pure images of the Sun with the 40 arcsec slit. In these images Doppler shifts are seen as horizontal brightenings. Inside the image it is difficult to distinguish shifts from horizontal structures but emission beyond the image edge can be unambiguously identified as a line shift in several lines separated from others on their blue or red side by more than the width of the spectrometer slit (40 pixels). In the blue wing of He II, we find a large number of events with properties (size and lifetime) similar to the well-studied explosive events seen in the ultraviolet spectral range. Comparison with X-Ray Telescope (XRT) images shows many Doppler shift events at the footpoints of small X-ray loops. The most spectacular event observed showed a strong blue shift in transition region and lower corona lines from a small X-ray spot that lasted less than 7 min. The emission appears to be near a cool coronal loop connecting an X-ray bright point to an adjacent region of quiet Sun. The width of the emission implies a line-of-sight velocity of 220 km/s. In addition, we show an example of an Fe XV shift with a velocity about 120 km/s, coming from what looks like a narrow loop leg connecting a small X-ray brightening to a larger region of X-ray emission.

Thermal shock resistance parameters for the industrial lining problem
Creators: name: Bradley, Frederick Joseph
Publisher: name: University of British Columbia
Year: 2010

description: A two-dimensional constant heating rate thermoelastic model has been used to develop design and selection criteria for refractory components of linings of high-temperature furnaces and process vessels. The criteria are in the form of resistance to fracture initiation and resistance to damage parameters which account for the influence of thermal and mechanical properties, geometry, and temperature range, while distinguishing between the heating and cooling cases. The resistance to fracture initiation parameter ɸs is the maximum rate at which a shape can be heated or cooled through a specified temperature range without causing fracture. The damage resistance parameter Rd is expressed as the ratio of surface energy per unit area to the elastic strain energy available for crack propagation. Both parameters can be quickly estimated for arbitrary conditions with the aid of tabulated solutions for the maximum principal tensile stress and total strain energy Thermoelastic analyses were used to interpret published results of a variety of thermal shock experiments. Thermal conditions associated with water quenching, radiative furnace heating, gas burners, and controlled heating were simulated using appropriate analytical solutions. Finite element analysis was used to compute maximum principal tensile stresses and elastic strain energy. A simple procedure was developed to invert the stress solution and thereby determine the instant of fracture. Good agreement between thermoelastic predictions and published experimental results with regard to strength retained versus thermal shock relationships, location of fracture, and safe heating rates provided justification for a thermoelastic approach to the thermal shock.

description: In the framework of an extended Nambu--Jona-Lasinio model we are studying pion condensation in quark matter with an asymmetric isospin composition in a gravitational field of the static Einstein universe at finite temperature and chemical potential. This particular choice of the gravitational field configuration enables us to investigate phase transitions of the system with exact consideration of the role of this field in the formation of quark and pion condensates and to point out its influence on the phase portraits. We demonstrate the effect of oscillations of the thermodynamic quantities as functions of the curvature and also refer to a certain similarity between the behavior of these quantities as functions of curvature and finite temperature. Finally, the role of quantum fluctuations for spontaneous symmetry breaking in the case of a finite volume of the universe is shortly discussed.

description: The dynamics of transformation twins in SrxBa1-xSnO3 (x=0.6,0.8) perovskite has been studied by dynamical mechanical analysis in three-point bend geometry. This material undergoes phase transitions from orthorhombic to tetragonal and cubic structures on heating. The mechanical loss signatures of the transformation twins include relaxation and frequency-independent peaks in the orthorhombic and tetragonal phases, with no observed energy dissipation in the cubic phase. The macroscopic shape, orientation and relative displacements of twin walls have been calculated from bending and anisotropy energies. The mechanical loss angle and distribution of relaxation time are discussed in term of bending modes of domain walls.

An explicit solution of wave function is studied in a simple two-dimensional minisuperspace model.

description: According to more recent AdS/CFT interpretation \cite{Karch:2015rpa}, in which varying cosmological constant $Λ$ in the bulk corresponds to varying the curvature radius governing the space on which the field theory resides, we study the criticality of thermodynamic curvatures for thermal boundary conformal field theories (CFT) that are dual to $d$-dimensional charged anti-de Sitter (AdS) black holes, embedded in $D$-dimensional M-theory/superstring inspired models having $AdS_{d}\times \mathbb{S}^{d+k}$ spacetime with $D=2d+k$. Analogous with criticality features acquired for charged AdS black holes in the bulk \cite{HosseiniMansoori:2020jrx}, the normalized intrinsic curvature $R_N$ and extrinsic curvature $K_N$ of the boundary CFT has critical exponents 2 and 1, respectively. In this respect, the universal amplitude of $R_Nt^2$ is $\frac{1}{2}$ and $K_Nt$ is $-\frac{1}{2}$ when $t\rightarrow0^-$, whereas $R_Nt^2\approx \frac{1}{8}$ and $K_Nt\approx\frac{1}{4}$ in the limit $t\rightarrow0^+$ in which $t=T/T_c-1$ is the temperature parameter with the critical temperature, $T_{c}$. Interestingly, these critical amplitudes are independent of the number of thermal CFT dimensions and are remarkably similar to one given for higher dimensional charged AdS black holes in the bulk.

description: Streaming 360° video demands high bandwidth and low latency, and poses significant challenges to Internet Service Providers (ISPs) and Mobile Network Operators (MNOs). The identification of 360° video traffic can therefore benefits fixed and mobile carriers to optimize their network and provide better Quality of Experience (QoE) to the user. However, end-to-end encryption of network traffic has obstructed identifying those 360° videos from regular videos. As a solution this paper presents 360NorVic, a near-realtime and offline Machine Learning (ML) classification engine to distinguish 360° videos from regular videos when streamed from mobile devices. We collect packet and flow level data for over 800 video traces from YouTube & Facebook accounting for 200 unique videos under varying streaming conditions. Our results show that for near-realtime and offline classification at packet level, average accuracy exceeds 95%, and that for flow level, 360NorVic achieves more than 92% average accuracy. Finally, we pilot our solution in the commercial network of a large MNO showing the feasibility and effectiveness of 360NorVic in production settings.

description: We consider the problem of heat transport by vibrational modes (conduction) between Langevin thermostats connected by a central device. The latter is anharmonic and can be subject to large temperature differences and thus be out of equilibrium. We develop a self-consistent Green's function formalism to describe high-temperature and non-equilibrium transport, and derive a formula for the heat current for up to quartic anharmonicity (4th-order in the potential energy). We show the importance of including quartic terms in the anharmonic potential in order to properly describe thermal expansion and temperature dependence to leading order in anharmonicity. This formalism paves the way for accurate and efficient modeling of thermal transport in highly non-equilibrium situations beyond perturbation theory.

title: The role of effective communication on students' emotional response to assessment: Written assignment brief

description: The emotional aspect of assessment should not be ignored. Assessment permeates all aspects of higher education, and is central to students’ experiences. While it may not be possible, or even desirable, to remove all stress from assessment, the need to mitigate against confusion and misinterpretation is important. The written assignment brief is a key document in the assessment process, yet it has received little attention. A lack of clarity caused by poorly written or poorly explained assignment instructions means that students may not know what they are required to do. Some will argue that an overly prescriptive assignment brief reduces creativity and effectively results in “spoon-feeding” students. This article argues that an effective assignment brief builds students’ confidence and minimises anxiety, which reduces their cognitive load and promotes learning. The findings in this article are drawn from the qualitative stage of a mixed-methods PhD study conducted in the University of Limerick, which explored how written assignment briefs affected students’ understanding of the requirements, and students’ potential to perform effectively. One key finding was the impact of poor communication on the students’ experience of assessment; exacerbating emotions such as anxiety, stress, and panic. Providing students with examples, templates, and detailed assignment briefs were identified as beneficial in reducing negative emotions and cognitive load.

Numerical modeling of horizontal drain drainage in an open pit slope
Creators: name: Ge, Shemin
Publisher: name: University of British Columbia

description: A study has been made to evaluate the effects of horizontal drain drainage on the water table drawdown in open pit slopes. Two major parameters of a horizontal drain drainage system, length and spacing, were studied. A two dimensional finite element computer model was constructed to simulate the water flow into drains in rock slopes. Water flow in the saturated zone was assumed. The computer model was tested by the field data obtained from the LORNEX Mine in British Columbia and the data taken from INTRODUCTION TO GROUNDWATER MODELING (Wang & Anderson, 1982). Satisfactory agreements were obtained. As the result of computer simulations, a series of graphs were plotted. These graphs show the relationship between hydraulic head distribution vs. drain spacing and length. They could be used in horizontal drain design as an aid to determine the spacing and length of a drain system. The computer simulations were also made to study the drainage characteristics of anisotropic rock slopes. The results indicated the influence of such rock conditions on the drainage effect. Another feature of mining slopes is that their height varies as the mining operation progresses. Therefore, the suitable vertical spacing between drain rows was investigated by computer simulation. A comparison of the drainage effects of different drain patterns, parallel drain and fanned drain layouts, was also made.

description: Gene Ontology (GO) is a structured repository of concepts (GO-terms) including three sub-ontologies, biological process (BP), molecular function (MF), and cellular component (CC). Although gene products should be ideally annotated in the three sub-ontologies, in-silico annotation methods usually cover individual sub-ontologies. Regarding cross-ontology annotations, methods based on cross-ontology association rules and interaction networks can be mentioned. However, the applicability of these methods is limited, since association rules can only be used with GO transitive relationships and interaction networks need huge amounts of curated data - only available for model organisms.
In this contribution, we present a method for automatic cross-ontology GO annotation, with no restriction on ontology relationships and no requirement of interaction data.
Magnetic trapping of silver and copper, and anomolous spin relaxation in the Ag-He system

description: We have trapped large numbers of copper and silver atoms using buffer gas cooling. Up to 3x10^12 copper atoms and 4x10^13 silver atoms are trapped. Lifetimes are as long as 5 s, limited by collisions with the buffer gas. Ratios of elastic to inelastic collision rates with He are >~ 10^6, suggesting copper and silver are favorable for use in ultracold applications. The temperature dependence of the silver-helium-3 collision rate varies as T^5.8. We find that this temperature dependence is inconsistent with the behavior predicted for relaxation arising from the spin-rotation interaction, and conclude that the silver-helium-3 system displays anomalous collisional behavior in the multiple-partial wave regime. Lifetimes of laser ablated gold in helium-3 buffer gas are too short to permit trapping.

La libertà universitaria sotto attacco in Brasile

description: The election of Jair Messias Bolsonaro as President of the Republic on October 28, 2018 marked a radical change in Brazilian politics. This essay focuses on the limits imposed on university autonomy, as well as on freedom of teaching and opinion. More specifically, it observes the interventions put into effect by the Electoral Justice and the police in several universities throughout Brazil, in order to repress standard academic activities that were considered ‘illicit electoral propaganda’. The program of the current presidency includes the draft law on ‘School without party’, which invites students of primary and secondary schools to film with their mobile phones teachers who carry out activities deemed to be political ‘indoctrination’ and to upload those videos on a dedicated website. In Germany, a similar project is promoted by the extreme right-wing party ‘Alternative für Deutschland’ (AfD). However, in Germany intervening in such a way is more complex than in Brazil, thanks to the different organization of teaching (which is analyzed in the text). The climate of tension generated by these measures is documented by the Supremo Tribunal Federal’s sentence on these interventions and on the Chamber of Deputies’ draft law that should implement the ‘Programa Escola sem Partido’.
