Abstract

Abstract The Search for Hidden Particles (SHiP) Collaboration has proposed a general-purpose experimental facility operating in beam-dump mode at the CERN SPS accelerator to search for light, feebly interacting particles. In the baseline configuration, the SHiP experiment incorporates two complementary detectors. The upstream detector is designed for recoil signatures of light dark matter (LDM) scattering and for neutrino physics, in particular with tau neutrinos. It consists of a spectrometer magnet housing a layered detector system with high-density LDM/neutrino target plates, emulsion-film technology and electronic high-precision tracking. The total detector target mass amounts to about eight tonnes. The downstream detector system aims at measuring visible decays of feebly interacting particles to both fully reconstructed final states and to partially reconstructed final states with neutrinos, in a nearly background-free environment. The detector consists of a 50 $$\mathrm { \,m}$$ m long decay volume under vacuum followed by a spectrometer and particle identification system with a rectangular acceptance of 5 m in width and 10 m in height. Using the high-intensity beam of 400 $$\,\mathrm {GeV}$$ GeV protons, the experiment aims at profiting from the $$4\times 10^{19}$$ 4 × 10 19 protons per year that are currently unexploited at the SPS, over a period of 5–10 years. This allows probing dark photons, dark scalars and pseudo-scalars, and heavy neutral leptons with GeV-scale masses in the direct searches at sensitivities that largely exceed those of existing and projected experiments. The sensitivity to light dark matter through scattering reaches well below the dark matter relic density limits in the range from a few $${\mathrm {\,MeV\!/}c^2}$$ MeV / c 2 up to 100 MeV-scale masses, and it will be possible to study tau neutrino interactions with unprecedented statistics. This paper describes the SHiP experiment baseline setup and the detector systems, together with performance results from prototypes in test beams, as it was prepared for the 2020 Update of the European Strategy for Particle Physics. The expected detector performance from simulation is summarised at the end.

Abstract

Abstract Dark photons are hypothetical massive vector particles that could mix with ordinary photons. The simplest theoretical model is fully characterised by only two parameters: the mass of the dark photon m $$_{\gamma ^{\mathrm {D}}}$$ γ D and its mixing parameter with the photon, $$\varepsilon $$ ε . The sensitivity of the SHiP detector is reviewed for dark photons in the mass range between 0.002 and 10 GeV. Different production mechanisms are simulated, with the dark photons decaying to pairs of visible fermions, including both leptons and quarks. Exclusion contours are presented and compared with those of past experiments. The SHiP detector is expected to have a unique sensitivity for m $$_{\gamma ^{\mathrm {D}}}$$ γ D ranging between 0.8 and 3.3 $$^{+0.2}_{-0.5}$$ - 0.5 + 0.2 GeV, and $$\varepsilon ^2$$ ε 2 ranging between $$10^{-11}$$ 10 - 11 and $$10^{-17}$$ 10 - 17 .

Abstract

Abstract Dark matter is a well-established theoretical addition to the Standard Model supported by many observations in modern astrophysics and cosmology. In this context, the existence of weakly interacting massive particles represents an appealing solution to the observed thermal relic in the Universe. Indeed, a large experimental campaign is ongoing for the detection of such particles in the sub-GeV mass range. Adopting the benchmark scenario for light dark matter particles produced in the decay of a dark photon, with α D = 0.1 and m A′ = 3m χ , we study the potential of the SHiP experiment to detect such elusive particles through its Scattering and Neutrino detector (SND). In its 5-years run, corresponding to 2 · 1020 protons on target from the CERN SPS, we find that SHiP will improve the current limits in the mass range for the dark matter from about 1 MeV to 300 MeV. In particular, we show that SHiP will probe the thermal target for Majorana candidates in most of this mass window and even reach the Pseudo-Dirac thermal relic.

Abstract

Abstract An event topology with two secondary vertices compatible with the decay of short-lived particles was found in the analysis of neutrino interactions in the OPERA target. The observed topology is compatible with tau neutrino charged current (CC) interactions with charm production and neutrino neutral current (NC) interactions with $$c\overline{c}$$ cc¯ pair production. However, other processes can mimic this topology. A dedicated analysis was implemented to identify the underlying process. A Monte Carlo simulation was developed and complementary procedures were introduced in the kinematic reconstruction. A multivariate analysis technique was used to achieve an optimal separation of signal from background. Most likely, this event is a $$\nu _{\tau }$$ ντ CC interaction with charm production, the tau and charm particle decaying into 1 prong and 2 prongs, respectively. The significance of this observation is evaluated.

Abstract

Abstract The SHiP experiment is proposed to search for very weakly interacting particles beyond the Standard Model which are produced in a 400 GeV/c proton beam dump at the CERN SPS. About $$10^{11}$$ 1011 muons per spill will be produced in the dump. To design the experiment such that the muon-induced background is minimized, a precise knowledge of the muon spectrum is required. To validate the muon flux generated by our Pythia and GEANT4 based Monte Carlo simulation (FairShip), we have measured the muon flux emanating from a SHiP-like target at the SPS. This target, consisting of 13 interaction lengths of slabs of molybdenum and tungsten, followed by a 2.4 m iron hadron absorber was placed in the H4 400 GeV/c proton beam line. To identify muons and to measure the momentum spectrum, a spectrometer instrumented with drift tubes and a muon tagger were used. During a 3-week period a dataset for analysis corresponding to $$(3.27\pm 0.07)~\times ~10^{11}$$ (3.27±0.07)×1011 protons on target was recorded. This amounts to approximatively 1% of a SHiP spill.

Abstract

Abstract Heavy Neutral Leptons (HNLs) are hypothetical particles predicted by many extensions of the Standard Model. These particles can, among other things, explain the origin of neutrino masses, generate the observed matter-antimatter asymmetry in the Universe and provide a dark matter candidate. The SHiP experiment will be able to search for HNLs produced in decays of heavy mesons and travelling distances ranging between O $$ \mathcal{O} $$ (50 m) and tens of kilometers before decaying. We present the sensitivity of the SHiP experiment to a number of HNL’s benchmark models and provide a way to calculate the SHiP’s sensitivity to HNLs for arbitrary patterns of flavour mixings. The corresponding tools and data files are also made publicly available.

Abstract

Abstract Direct Dark Matter searches are nowadays one of the most fervid research topics with many experimental efforts devoted to the search for nuclear recoils induced by the scattering of Weakly Interactive Massive Particles (WIMPs). Detectors able to reconstruct the direction of the nucleus recoiling against the scattering WIMP are opening a new frontier to possibly extend Dark Matter searches beyond the neutrino background. Exploiting directionality would also prove the galactic origin of Dark Matter with an unambiguous signal-to-background separation. Indeed, the angular distribution of recoiled nuclei is centered around the direction of the Cygnus constellation, while the background distribution is expected to be isotropic. Current directional experiments are based on gas TPC whose sensitivity is limited by the small achievable detector mass. In this paper we present the discovery potential of a directional experiment based on the use of a solid target made of newly developed nuclear emulsions and of optical read-out systems reaching unprecedented nanometric resolution.

Abstract

Abstract The OPERA experiment has discovered the tau neutrino appearance in the CNGS muon neutrino beam, in agreement with the 3 neutrino flavour oscillation hypothesis. The OPERA neutrino interaction target, made of Emulsion Cloud Chambers, was particularly efficient in the reconstruction of electromagnetic showers. Moreover, thanks to the very high granularity of the emulsion films, showers induced by electrons can be distinguished from those induced by π 0s, thus allowing the detection of charged current interactions of electron neutrinos. In this paper the results of the search for electron neutrino events using the full dataset are reported. An improved method for the electron neutrino energy estimation is exploited. Data are compatible with the 3 neutrino flavour mixing model expectations and are used to set limits on the oscillation parameters of the 3+1 neutrino mixing model, in which an additional mass eigenstate m 4 is introduced. At high Δm 412 (≳0.1 eV2), an upper limit on sin2 2θ μe is set to 0.021 at 90% C.L. and Δm 412 ≳ 4 × 10− 3 eV2 is excluded for maximal mixing in appearance mode.

Abstract

Abstract The OPERA experiment was designed to search for $$\nu _{\mu } \rightarrow \nu _{\tau }$$ νμ→ντ oscillations in appearance mode through the direct observation of tau neutrinos in the CNGS neutrino beam. In this paper, we report a study of the multiplicity of charged particles produced in charged-current neutrino interactions in lead. We present charged hadron average multiplicities, their dispersion and investigate the KNO scaling in different kinematical regions. The results are presented in detail in the form of tables that can be used in the validation of Monte Carlo generators of neutrino–lead interactions.

Abstract

It is suggested that hyperuricemia is a marker of cardiovascular risk in human adults with metabolic syndrome (MS). The C677T polymorphism in the gene encoding the enzyme methylenetetrahydrofolate reductase (MTHFR) is associated with hyperuricemia. Data on factors associated with uricemia in human adults with MS genotyped for this polymorphism are lacking. We aimed to investigate the factors associated with uricemia in human adults with MS genotyped for the C677T polymorphism in the MTHFR gene. Cross-sectional study was conducted with 63 human adults (24 men and 39 women) with MS. Body weight, body mass index, waist circumference, body fat, glycemia, lipid profile, uricemia, insulinemia, homocysteinemia, plasma folate, erythrocyte folate, blood pressure, smoking, diuretics use, usual dietary alcohol and protein intakes, MTHFR and the presence of the C677T polymorphism in the gene were assessed. Hyperuricemia was observed in 16 (25.4%) human adults (10 men and 6 women). In the group, 33% (n = 21) showed the C677T polymorphism, being 19 heterozygous and 2 mutant homozygous. A significant association between hyperuricemia and C677T polymorphism was not verified. Uricemia was positively associated with homocys-teinemia (r = 0.43, p < 0.05), triglyceridemia (r = 0.41, pSugérese que la hiperuricema sea un factor de riesgo cardiovascular en humanos adultos con síndrome meta-bólico (SM) El polimorfismo C677T en el gen metilenote-trahidrofolato reductasa (MTHFR) ha sido asociado com la hiperuricemia. Datos sobre los factores asociados con la uricemia en humanos adultos con SM genotipados para el polimorfismo C677T en el gen MTHFR son inexistentes. Se objetivó investigar los factores asociados con la uricemia en individuos con SM genotipados para el polimorfismo C677T.Se ha realizado un estudio transversal con 63 humanos adultos (24 hombres y 39 mujeres). Fueron evaluados peso, altura, índice de masa corporal, circunferencia de la cintura, grasa corporal total, glucemia, uricemia, insulinemia, homocisteinemia, folato plasmático, folato en los eritrocitos, presión arterial, tabaquismo, uso de diuréticos, ingesta habitual de proteínas dietéticas y de alcohol y la presencia del polimorfismo C677T. No fue encontrado asociación significativa entre el polimorfismo C677T y la uricemia. Fue verificado que un 25,4% (n = 16) ddo los individuos presentaban hiperuri-cemia (10 hombres y 6 mujeres). Se verificó que un 33% (n = 21) de olos individuos presentaron el polimorfismo C677T (19 heterocigotos y 2 homocigotos polimórficos). La uricemia se asoció con los niveles de homocisteina (r = 0,43, p < 0,05), trigicéridos (r = 0,41, p < 0,05) y de lipo-proteínas de muy baja densidad (r = 0.27, p < 0,05) y con la ingesta de alcohol (r = 0,37, p < 0,05). Sin embargo, sólo la homocisteinemia, la trigliceridemia y la ingesta habitual de alcohol permanecerán en el modelo final de regresión lineal. En los humanos adultos con SM genotipados para el polimorfismo C677T en el gen MTHFR, la uricemia se asoció positivamente con los niveles de homocisteína y triglicéridos y con la ingesta habitual de alcohol.

Abstract

Introducción: El receptor activado por proliferadores de peroxisomas (PPARγ2) es un factor de transcripción adipogénico que influye en la resistencia a la insulina (RI) en la presencia de agonistas como los ácidos grasos poliinsaturados (AGPI). Objetivo: Evaluar la influencia de la grasa de la dieta en el metabolismo glucídico de mujeres con obesidad mórbida y con el genotipo Pro12Pro en el gen PPARγ2. Métodos: Fueron seleccionadas 25 mujeres con genotipo Pro12Pro. La ingesta habitual de lípidos fue estimada por registros alimentarios, siendo utilizada para la división de los grupos, GA (hasta un 30% del valor energético total (VET)) y GB (por encima de un 30% del VET). Fueron realizadas evaluaciones bioquímicas y antropométricas en ayuno, siguiendo la comida test rica en AGPI n-6 y los análisis bioquímicos postprandiales en GA y GB. La RI y la sensibilidad a la insulina (SI) fueron evaluadas por HOMA-IR (Homeostasis Model Assessment) y QUICKI (Quantitative Insulin Sensitivity Check Index), respectivamente. Resultados y discusión: GA presentó HOMA-IR y QUICKI normales. GB presentó el índice de masa corporal (IMC), HOMA-IR, ingesta de ácidos grasos saturados (AGS) y monoinsaturados (AGMI) superiores a GA (p < 0,05). En GB, los AGMI se correlacionaron negativamente con HOMA-IR, glucosa e insulina en ayuno, y positivamente con QUICKI. Los lípidios totales y AGS contribuyeron al aumento de la masa corporal y RI. Sin embargo, los AGMI parecen reducir el impacto de la dieta hiperlipídica en el metabolismo glucídico. Se propone que mujeres obesas con el genotipo Pro12Pro en el gen PPARγ2 eviten dietas ricas en lípidos y AGS, priorizando AGMI para el control de la obesidad y mejora de la SI.Introduction: The peroxisome proliferator-activated receptor gamma 2 (PPARγ2) is an adipogenic transcription factor that influences in insulin resistance (IR) in the presence of agonists such as polyunsaturated fatty acids (PUFA). Objective: Evaluate the influence of dietary fat in glicidic metabolism in morbidly obese women with Pro12Pro genotype in the gene PPARγ2. Methods: Were selected 25 women with genotype Pro12Pro. The fat intake was estimated by food records, being used for the division of groups, GA (until 30% of the total energy expenditure (TEE)) and GB (greater than 30% of the TEE). Biochemical and anthropometric evaluations were conducted in fasting, following the test meal high in n-6 PUFA and postprandial biochemical evaluations. IR and insulin sensitivity (IS) were assessed by HOMA-IR (Homeostasis Model Assessment) and QUICKI (Quantitative Insulin Sensitivity Check Index), respectively. Results and discussion: GA presented normal HOMAIR and QUICKI. GB presented higher body mass index (BMI), HOMA-IR, saturated fatty acids (SFA) and monounsaturated (MUFA) intake higher, compared with GA (p < 0.05). In GA, the MUFA intake was negatively correlated with HOMA-IR, fasting glucose and insulin, and positively with QUICKI. The fat and SFA intake contributed to the increase in body mass and IR. However, MUFA intake may have reduced the impact of high fat diet in glicidic metabolism. It is suggested that obese women with Pro12Pro genotype in the PPARγ2 gene avoid high fat and SFA diets, prioritizing MUFA for controlling obesity and improving the IS.

Abstract

Neste artigo, analisamos as campanhas oficiais dos(as) candidatos(as) às prefeituras de todas as capitais brasileiras, em 2020, no Facebook. A partir de técnicas de estatística descritiva e da análise de enquadramentos, observamos os atores e narrativas com melhor desempenho na rede e suas principais características, como posicionamento no espectro político, enquadramentos, alinhamentos e recursos comunicacionais. Os resultados mostram a reação da esquerda na rede após as eleições de 2018, liderada por páginas de partidos pequenos, que usaram a plataforma principalmente para discutir conjuntura e questões identitárias. Contudo, mantiveram-se como tendência as práticas de campanha negativa e o agendamento de temas de apelo subjetivo, como família e religião, sobretudo entre as páginas apoiadoras de Bolsonaro, político mais referenciado durante o pleito. Abstract In this article, we analyze the official campaigns of the candidates for city halls of all Brazilian state capitals in 2020 on Facebook. Using descriptive statistical techniques and frame analysis, we observe the best performing actors and narratives on the network and their main characteristics, such as positioning on the political spectrum, frames, alignments, and communication resources. Our results show the reaction of leftists on the social network following the 2018 elections, analyzing the posts on the profiles of small parties, which used the platform mainly to discuss the wider political conjuncture and identity issues. However, negative campaign practices and giving priority to themes with subjective appeal, such as family and religion, remained a trend, especially among pages supporting Bolsonaro, the most referenced politician during the election. Resumen En este artículo, analizamos las campañas oficiales de los candidatos a las alcaldías de las capitales de todos los estados brasileños en 2020 en Facebook. Utilizando técnicas de estadística descriptiva y análisis de marcos, observamos los actores y narrativas que mejor funcionan en la red y sus principales características, como el posicionamiento en el espectro político, los marcos, los alineamientos y los recursos de comunicación. Nuestros resultados muestran la reacción de la izquierda en la red tras las elecciones de 2018, liderada por páginas de partidos pequeños, que utilizaron la plataforma principalmente para debatir sobre la coyuntura y cuestiones identitarias. Sin embargo, las prácticas negativas de campaña y la programación de temas de apelación subjetiva, como la familia y la religión, se mantuvieron como tendencia, especialmente entre las páginas que apoyan a Bolsonaro, el político más referenciado durante las elecciones. Résumé Dans cet article, nous analysons les campagnes officielles des candidats aux mairies des capitales de tous les états brésiliens en 2020 sur Facebook.

Abstract

The objective of this study was to evaluate the effects of a training session with and without an intervention of postactivation performance enhancement (PAPE) on countermovement jump (CMJ) height, perceived recovery status (PRS), and ratings of perceived exertion (RPEs), followed by a specific volleyball training session. The sample consisted of sixteen professional male volleyball players, with an average age of 26.8±6.1 years and average height of 195.9±6.7 cm, randomly divided into a group with PAPE intervention (GPAPE) (n=8), and a control group (CTRL) without PAPE intervention (n=8). The control group carried out the training session with plyometric exercises, and the GPAPE added conditioning protocols for PAPE to plyometric training, followed by a technical tactical volleyball session. At the end of the training session, there was an increase of 16.3% in the height of the CMJ in the GPAPE, while the CTRL showed a decrease of 5% in the height of the CMJ. PRS and RPE variables did not differ between the groups. It was concluded that PAPE had a positive effect on the height of the vertical jump after plyometric training, which was maintained until the end of the technical and tactical volleyball session.

Abstract

Purpose: The authors aimed to compare the effects of 4 weeks jump versus complex training methods on lower limb muscle power and maximal isokinetic torque of knee extensors and flexors in elite male volleyball players. Methods: Sixteen male volleyball players were allocated into 2 groups, jump training (n = 8; 27.0 [5.7] y, 94.3 [7.6] kg) and complex training (with induction of postactivation performance enhancement, n = 8; 26.6 [3.6] y, 94.2 [6.3] kg). All individuals performed jump training 2 sessions/wk, and the complex group received induction training with postactivation performance enhancement and jump training. Results: After 4 weeks, an increase in countermovement jump height (jump: 49.0 [1.2] to 52.7 [2.1] cm and complex: 49.2 [1.1] to 53.3 [1.9] cm; P = .009) and power (jump: 29.5 [1.1] to 34.3 [1.4] W and complex: 30.4 [0.9] to 34.4 [1.08] W; P = .001) was observed without significant differences between groups and without significant group × time interaction (P > .05). Also, no significant difference was observed between and within groups for the isokinetic peak torque at low speeds (60 and 180°s), although total muscle work and knee extensor/flexor ratio increased from pretraining to posttraining at 300° seconds similarly in both groups. Conclusion: The findings indicate that jump performance and power, knee extensor/flexor ratio, and total muscle work increased after 4 weeks of jump and complex training. However, the inclusion of heavy resistance stimulus did not elicit any additional improvements in the vertical jump performance and isokinetic strength of elite volleyball players.

Abstract

Urinary bladder volume monitoring can benefit from contactless measurements, as alternative to the traditional medical methods of transurethral catheterization or ultrasound examination. The emerging modality of Magnetic Induction Tomography (MIT) offers the possibility for estimation of the intravesical volume in the physiological and pathological states using conductivity map reconstructions of the tissues present in the pelvic region. Within MIT, eddy currents originating from the conductive urine can produce their own magnetic field in response to an external magnetic source that is susceptible of being detected outside the body by means of a static ring of sensing coils. However, the ill-conditioned and ill-posed nature of the MIT Inverse Problem make the numerical implementation and conductivity estimation highly laborious. In this paper, we present a rotational frame model based on the MIT principles with application in urodynamic studies, which allows to extend the number of contactless measurements without increasing the overall dimension of the simulation domain, at the expense of solving multiple MIT Forward Problems. On the inversion process, the single-step Gauss-Newton method with Laplacian regularizer is recruited to estimate the bladder volume non-invasively and remotely (estimation error of 19%) using a simplified (quasi 2D) approximation to the distribution of eddy currents in the examined region, therefore paving the way for this technique to surpass the current limitations found in intravesical volume monitoring.

Abstract

Resumo Fundamento Apesar da necessidade de opções terapêuticas específicas para a doença do coronavírus 2019 (covid-19), ainda não há evidências da eficácia de tratamentos específicos no contexto ambulatorial. Há poucos estudos randomizados que avaliam a hidroxicloroquina (HCQ) em pacientes não hospitalizados. Esses estudos não indicaram benefício com o uso da HCQ; no entanto, avaliaram desfechos primários diferentes e apresentaram vieses importantes na avaliação dos desfechos. Objetivo Investigar se a HCQ possui o potencial de prevenir hospitalizações por covid-19 quando comparada ao placebo correspondente. Métodos O estudo COVID-19 Outpatient Prevention Evaluation (COPE) é um ensaio clínico randomizado, pragmático, duplo-cego, multicêntrico e controlado por placebo que avalia o uso da HCQ (800 mg no dia 1 e 400 mg do dia 2 ao dia 7) ou placebo correspondente na prevenção de hospitalizações por covid-19 em casos precoces confirmados ou suspeitos de pacientes não hospitalizados. Os critérios de inclusão são adultos (≥ 18 anos) que procuraram atendimento médico com sintomas leves de covid-19, com randomização ≤ 7 dias após o início dos sintomas, sem indicação de hospitalização na triagem do estudo e com pelo menos um fator de risco para complicações (> 65 anos, hipertensão, diabetes melito, asma, doença pulmonar obstrutiva crônica ou outras doenças pulmonares crônicas, tabagismo, imunossupressão ou obesidade). Todos os testes de hipótese serão bilaterais. Um valor de p < 0,05 será considerado estatisticamente significativo em todas as análises. Clinicaltrials.gov: NCT04466540. Resultados Os desfechos clínicos serão avaliados centralmente por um comitê de eventos clínicos independente cegado para a alocação dos grupos de tratamento. O desfecho primário de eficácia será avaliado de acordo com o princípio da intenção de tratar. Conclusão Este estudo apresenta o potencial de responder de forma confiável a questão científica do uso da HCQ em pacientes ambulatoriais com covid-19. Do nosso conhecimento, este é o maior estudo avaliando o uso de HCQ em indivíduos com covid-19 não hospitalizados.

Abstract

The creative city is one of the ways found by UNESCO to highlight new ways for cities to carry out their economic processes, related or applied in the routines of the regions. The objective of this study was to identify the characteristics that make the Integrated Region of Economic Development (RIDE) of the Petrolina Pole (PE) - Juazeiro (BA) a potential candidate for a vacancy in the select group of the Creative Cities Network - RCC of the United Nations Educational, Scientific and Cultural Organization (UNESCO). In addition, it was intended to point out the benefits of the insertion of the region in this network, which, among other objectives, seeks cooperation between cities, cultural, tourist, creative, economic development, and the reduction of social inequalities, through the Creative Economy. Thus, it is a qualitative, exploratory, descriptive, and bibliographical research, where for its development was used the systematic literature review (RSL) in order to meet relevant criteria. The main findings indicate that the RIDE region of Petrolina has characteristics and elements such as transport infrastructure and socio-environmental and cultural potential that can make it a hub of creative economic development.

Abstract

Small-grain crop growers need to match their crops' nitrogen (N) needs with fertilizer applications. This can be challenging because small grains are grown under diverse conditions and their growing season interacts with unpredictable precipitation. Resulting conditions can lead to nitrate-N leaching and runoff losses. More widespread and accurate soil N testing could help growers improve N fertilizer use efficiency, reduce the risk of N loss, and fulfill regulatory requirements. Soil samples from across California small-grain growing regions were tested with a soil nitrate quick test as well as standard laboratory procedures. The quick test is inexpensive and easy to use, and it provides rapid results. A correction factor was developed to convert the quick test values to lab and fertilizer equivalents. The correction factor is based on site-specific soil bulk density and the extracting solution used. An interactive webtool was developed that integrates this information for users. The quick tests provide accurate, real-time estimates of soil nitrate-N in the field to help improve fertilizer use efficiency and reduce N losses.

Abstract

The measurement of environmental neutrons is particularly important in the search for new physics, such as dark matter particles, because neutrons constitute an often-irreducible background source. The measurement of the neutron energy spectra in the sub-MeV scale is technically difficult because it requires a very good energy resolution and a very high $\gamma$-ray rejection power. In this study, we used a super-fine-grained nuclear emulsion, called Nano Imaging Tracker (NIT), as a neutron detector. The main target of neutrons is the hydrogen (proton) content of emulsion films. Through a topological analysis, proton recoils induced by neutron scattering can be detected as tracks with sub-micrometric accuracy. This method shows an extremely high $\gamma$-ray rejection power, at the level of $5 \times 10^7 ~ \gamma/\rm{cm}^2$, which is equivalent to 5 years accumulation of environmental $\gamma$-rays, and a very good energy and direction resolution even in the sub-MeV energy region. In order to carry out this measurement with sufficient statistics, we upgraded the automated scanning system to achieve a speed of 250 g/year/machine. We calibrated the detector performance of this system with 880 keV monochromatic neutrons: a very good agreement with the expectation was found for all the relevant kinematic variables. The application of the developed method to a sample exposed at the INFN Gran Sasso surface laboratory provided the first measurement of sub-MeV environmental neutrons with a flux of $(7.6 \pm 1.7) \times 10^{-3} \rm{cm}^{-2} \rm{s}^{-1}$ in the proton energy range between 0.25 and 1 MeV (corresponds to neutron energy range between 0.25 and 10 MeV), consistent with the prediction. The neutron energy and direction distributions also show a good agreement., Comment: 11 pages, 14 figures

Abstract

The evaluation of stone cladding material suitability can be a challenge due to the way that stone physical and mechanical properties, and characteristics such as mineralogy, might influence stone performance as a cladding element in a ventilated facade application. Salts can affect natural stone performance, and one of the experimental methods available to study and predict it is through accelerated aging tests such as salt fog chamber cycles. Aging test results should include the analysis of critical stone physical–mechanical properties to fully understand decay effects. The aim of this study was to reduce the lack of knowledge regarding the implications of salt fog on certain fundamental characteristics of stone cladding requirements, such as elastic properties and flexural strength, because these are particularly important properties for ventilated facade systems. A systematic methodology based on artificial salt fog cycles in a climatic chamber, microscopic analysis, weight measurement, flexural strength, and dynamic elastic modulus was performed on two limestones from Portugal: Moleanos (MO) and Semi-Rijo (SR). This study aims to contribute to improved selection stone methods linked to more sustainable stone facades, and the experimental methodology can be further applied to other stone types, particularly the ones most selected for stone cladding applications near coastal areas. In this work, results of salt fog decay cycles are presented and discussed considering their direct contribution for a better stone-cladding dimensioning process.

Abstract

Objetivo: As fraudes e adulterações no mel são fatores que comprometem a qualidade do produto, além de ser um risco para a saúde do consumidor. Esse artigo teve como objetivo, avaliar a qualidade da produção apícola comercializada em duas feiras permanentes no Distrito Federal, nos meses de agosto e outubro de 2017 e em janeiro e abril de 2018. Métodos: Foram utilizadas as metodologias preconizadas pelo Instituto Adolfo Lutz, para a determinação dos teores de açúcares redutores, sacarose aparente e hidroximetilfurfural, em amostras de méis produzidos por Apis melífera L. e, os resultados das análises foram comparados aos parâmetros preconizados pela legislação brasileira vigente. Resultados: Identificou-se que as amostras dos meses de agosto de 2017 e abril de 2018 apresentaram melhor qualidade, pois apresentaram todos os parâmetros analisados de acordo com a legislação vigente. Conclusão: A partir das análises realizadas, observou-se a grande necessidade de constantes fiscalizações através de análises laboratoriais, a fim de assegurar tanto a qualidade nutricional como a segurança alimentar para os consumidores de tais produtos, uma vez que, no Distrito Federal, ainda há poucos estudos em relação à produção local e, principalmente, dos pequenos apicultores que produzem e comercializam o produto de forma informal.

Abstract

Objetivo: Esse trabalho teve como objetivo avaliar a concentração proteica em 21 genótipos de quinoa (Chenopodium quinoa willd.) utilizados no Programa de Melhoramento de Quinoa da Universidade de Brasília – DF. Métodos: A metodologia utilizada foi a análise físico-química para determinação de teores de proteinas através do método semi micro Kjeldahl, em bloco digestor, segundo metodologia preconizada pelo Instituto Adolfo Lutz. Resultados: A partir das amostras analisadas observou-se que, dos 21 genótipos, apenas três (34ZL, 37ZL e 40ZL) se destacaram dentre os demais, com medias superiores a 16% de proteínas. Conclusão: Em função dos resultados das análises realizadas, concluiu-se que estes genótipos (34ZL, 37ZL e 40ZL) devem ser priorizados no uso como parentais de hibridações controladas objetivando melhoria na qualidade proteica do grão.

Abstract

Antecedentes: La identificación de los factores de riesgo y posibles asociaciones biológicas y biomecánicas durante el desarrollo de la enfermedad perimplantar tienen como propósito contribuir a prevenir su ocurrencia. Objetivo: Determinar la frecuencia de las enfermedades perimplantares y posibles asociaciones con potenciales factores de riesgo. Métodos: Se realizó un estudio transversal retrospectivo en 75 pacientes con 318 implantes que se colocaron entre 2008 y 2015. Se recolectaron datos demográficos, clínicos y radiológicos requeridos para el diagnóstico de las enfermedades perimplantares a partir de la historia clínica y el examen físico en los pacientes que asistieron a control durante el tiempo de estudio. Resultados: La frecuencia total de las enfermedades perimplantares fue de 81,33 %. La frecuencia de mucositis perimplantar y perimplantitis fue del 74,7 % y 34,7 %, respectivamente. La frecuencia de mucositis perimplantar por implantes fue del 55,7 %, en tanto que la de perimplantitis por implantes fue del 20,7 %. La historia de enfermedad periodontal previa y actual y el tabaquismo parecen estar relacionados con la presencia de esta patología. Conclusiones: La frecuencia total de las enfermedades perimplantares fue de 81,33 % en los pacientes evaluados. La periodontitis como antecedente o enfermedad actual y la ausencia de una terapia de mantenimiento de apoyo parecen ser factores asociados al desarrollo y progreso de estas patologías.
