Published: September 2020

The overarching vision of Higher Learning Institutions that are concerned with construction education, is to nurture graduates that will be prepared to not only deal with the current needs of the Construction Industry, but also be able to immerse themselves confidently in a future full of complexity. However, the transition from University to work is often a daunting experience for graduates, and employers often complain that graduates are usually ill prepared for work. It is therefore important to understand the students’ perspective regarding level of work preparedness so that solutions can be sought, both from Universities and Industry, to make the transition from University to the world of work a truly empowering experience. This study investigated the level of preparedness to start work for final-year students (2019/20) pursuing a Bachelor of Science degree in Quantity Surveying (QSg) at University of Rwanda. An online questionnaire was designed and administered to 59 students to solicit their perceptions. Most students (42%) asserted that they were very prepared to start working as Quantity Surveyors, with some (12%) extremely prepared. Industrial Training stood out as the largest contributor in preparing students to start work, whereas University laboratory resources did not contribute much. Students exhibited most knowledge in core QSg competences, such as Estimating Costs of construction works. Although students were most confident in topics on Measurement of Finishes, students that had a Technical and Vocational Education and Training background exhibited greater confidence. The findings of this study provide important feedback for similar construction programs to evaluate and revise their curricula to better prepare QSg students for professional success in the Construction Industry.
A proteção da propriedade intelectual e o artesanato

O artigo trata de alguns casos de apropriação de produções artesanais pertencentes a comunidades mexicanas por marcas famosas como, por exemplo, Carolina Herrera. Também discorre sobre a atuação do governo nessa questão, bem como os dilemas enfrentados pelos artesãos das comunidades, pois, ainda que junto a Organizações Não-Governamentais (ONG’s) ou até entidades governamentais, os mesmos não possuem os meios necessários para contestar em âmbito internacional e disputar os direitos sobre suas criações. Nota-se claro descaso por parte dessas grandes marcas que utilizam-se do discurso da inspiração ou homenagem às comunidades, quase sempre não levando em conta as implicações econômicas e os impactos negativos sobre o patrimônio cultural dos povos que lutam pela manutenção e perpetuação daquilo que fora deixado por seus antepassados. Com isso, o artigo busca jogar luz ao debate sobre a garantia de proteção de criações artesanais tanto na legislação internacional de propriedade intelectual quanto na mexicana, refreando a ocorrência de casos deste tipo que prejudica comunidades locais.
Brechas na legislação de propriedade intelectual
Authors: Paulino Rosa Laryssa , Bilotta da Silva Renato 
Published: September 2020

O presente artigo tem como objetivo analisar o fenômeno dos legal fakes e como estes diferem da simples falsificação de produtos. Para tal, discute-se sobre as atuais legislações internacionais que regem o registro internacional de marcas comerciais, apontando seus dispositivos e as brechas existentes atualmente, além de apresentar uma perspectiva sobre o valor da marca atrelado a sua origem territorial e o consumo de marcas de luxo como forma de diferenciação social. O fenômeno é analisado através de dois casos paradigmáticos: a comercialização das marcas Boy London (com sede em Londres) e Supreme (com sede em Nova Iorque) por empresas sediadas na Itália e com autorização para o fazerem ainda que não sejam as proprietárias das marcas citadas. Conclui-se que o legal fake é uma estratégia nova e ainda não absorvida pelas jurisdições nacionais, criando assim diferentes entendimentos sobre o tema e a necessidade de uma pesquisa mais aprofundada por parte da academia e as organizações ligadas à propriedade intelectual.

X-Ray Spectroscopy in the Microcalorimeter Era. I. Effects of Fe xxiv Resonant Auger Destruction on Fe xxv Kα Spectra
Authors: Chakraborty P. , Ferland G. J. , Chatzikos M. , Guzmán F. , Su Y. 
Published: September 2020

Abstract
We discuss the importance of Fe23+ in determining the line intensities of the Fe xxv Kα complex in an optically thick cloud, and investigate resonant auger destruction (RAD) with CLOUDY. Although initially motivated by the Perseus cluster, our calculations are extended to the wide range of column densities encountered in astronomy. A Fe xxv line photon can change/lose its identity upon absorption by three-electron iron as a result of “line interlocking.” This may lead to the autoionization of the absorbing ion, ultimately destroying the Fe xxv Kα photon by RAD. Out of the four members in the Fe xxv Kα complex, a significant fraction of the x line photons are absorbed by Fe23+ and destroyed, causing the x line intensity to decrease. For example, at a hydrogen column density of 1025 cm−2, ∼32% of x photons are destroyed due to RAD while w is mostly unaffected. The line intensity of y is slightly (≤2%) reduced. z is not directly affected by RAD, but the contrasting behavior between z and x line intensities points toward the possible conversion of a tiny fraction (∼2%) of x photons into z photons. The change in line intensities due to electron scattering escape off fast thermal electrons is also discussed.
Formation of Foreshock Transients and Associated Secondary Shocks

Published: September 2020

Abstract
Upstream of shocks, the foreshock is filled with hot ions. When these ions are concentrated and thermalized around a discontinuity, a diamagnetic cavity bounded by compressional boundaries, referred to as a foreshock transient, forms. Sometimes, the upstream compressional boundary can further steepen into a secondary shock, which has been observed to accelerate particles and contribute to the primary shock acceleration. However, secondary shock formation conditions and processes are not fully understood. Using particle-in-cell simulations, we reveal how secondary shocks are formed. From 1D simulations, we show that electric fields play a critical role in shaping the shock’s magnetic field structure, as well as in coupling the energy of hot ions to that of the shock. We demonstrate that larger thermal speed and concentration ratio of hot ions favor the formation of a secondary shock. From a more realistic 2D simulation, we examine how a discontinuity interacts with foreshock ions leading to the formation of a foreshock transient and a secondary shock. Our results imply that secondary shocks are more likely to occur at primary shocks with higher Mach number. With the secondary shock’s previously proven ability to accelerate particles in cooperation with a planetary bow shock, it is even more appealing to consider them in particle acceleration of high Mach number astrophysical shocks.
Archival VLBA Observations of the Cygnus A Nuclear Radio Transient (Cyg A-2) Strengthen the Tidal Disruption Event Interpretation

Published: September 2020

Abstract
We have analyzed archival Very Long Baseline Array (VLBA) data for Cygnus A between 2002 and 2013, to search for radio emission from the transient discovered in 2015 by Perley et al. approximately 0.″4 from the nucleus of Cygnus A (Cyg A-2). Perley et al. use Very Large Array and VLBA archival data (between 1989 and 1997) to show that the transient rises in flux density by a factor of at least 5 in less than approximately 20 yr. With the additional data presented here, we revise the rise time to between approximately 4 and 6 yr, based on a new detection of the source at 15.4 GHz from 2011 October. Our results strengthen the interpretation of Cyg A-2 as the result of a tidal disruption event (TDE), as we can identify the location of the compact object responsible for the TDE and can estimate the angular expansion speed of the resulting radio-emitting structures, equivalent to an apparent expansion speed of <0.9c. While our results are consistent with recent X-ray analyses, we can rule out a previously suggested date of early 2013 for the timing of the TDE. We favor a timing between early 2009 and late 2011. Applying the model of Nakar & Piran, we suggest a TDE causing a mildly relativistic outflow with a (density-dependent) total energy >1049 erg. Due to the improved temporal coverage of our archival measurements, we find that it is unlikely that Cyg A-2 has previously been in a high luminosity radio state over the last 30 yr.

La pandémie de Covid-19 apparaît comme un miroir de la situation de l’Église catholique, aussi bien dans le champ liturgique, dans celui de la solidarité et dans celui du fonctionnement ecclésial. Le tableau est contrasté. Des habitudes cléricales ont cohabité avec des initiatives plus « synodales ». Des leçons sont à en tirer pour aller toujours davantage vers une « Église en sortie ».
IgG Immune Complexes Break Immune Tolerance of Human Microglia

Published: September 2020

Abstract
Microglia are phagocytic cells involved in homeostasis of the brain and are key players in the pathogenesis of multiple sclerosis (MS). A hallmark of MS diagnosis is the presence of IgG Abs, which appear as oligoclonal bands in the cerebrospinal fluid. In this study, we demonstrate that myelin obtained post mortem from 8 out of 11 MS brain donors is bound by IgG Abs. Importantly, we show that IgG immune complexes strongly potentiate activation of primary human microglia by breaking their tolerance for microbial stimuli, such as LPS and Poly I:C, resulting in increased production of key proinflammatory cytokines, such as TNF and IL-1β. We identified FcγRI and FcγRIIa as the two main responsible IgG receptors for the breaking of immune tolerance of microglia. Combined, these data indicate that IgG immune complexes potentiate inflammation by human microglia, which may play an important role in MS-associated inflammation and the formation of demyelinating lesions.

Published: September 2020

This study focused on the effects of variables related to nomophobia levels of youths for adults; and exhibited a nomophobia profile of an adult by means of the significant variables about adults. Two hundred-ten adults from 30 different occupational groups participated in the research. The relational research design was used in the research. Data after collecting through scales were subjected to logistic regression analysis and two-step clustering analysis. As a result of the analysis, it was determined that while the nomophobia scores of the participated adults who were married, had children, were 30 years and older, have higher life satisfaction scores and lower social media addiction scores were low. On the other hand, it was determined that the adult in high nomophobia scores were clustered in the group who were single and did not have children, were between the ages of 24-29, had low life satisfaction scores and high social media addiction.
Bayesian Coalition Game for Overlay D2D Spectrum Sharing in Cellular Networks
Authors: Gbenga-Ilori Abiodun O 
Published: September 2020

In this paper, we present a Bayesian coalition game model for spectrum sharing in order to increase the overall spectrum resource capacity in a cellular network with device-to-device (D2D) communication capabilities. The coalition game is used to enforce cooperation among D2Ds competing for the use of the limited spectrum resource. In this paper, D2D users can access the network in an overlaid mode and share their allocated sub-bands with other D2D users using the proposed game which enables coalition formation that guarantee an optimal rate for all users in the network. The paper establishes sufficient conditions needed for stability in the coalitions formed and present simulation results to show that it is possible to increase the overall capacity of the D2D-enabled cellular network without reducing the performance of the licensed cellular users using the proposed game. D2D spectrum sharing using our proposed algorithm was compared with spectrum sharing using the random pairing method to validate our game model. Results show that there was a 44% and 36% increase in cell sum-rate, when our proposed sub-band allocation game was deployed compared to the random pairing method, for the 50 and 100 cells respectively. The proposed sub-band allocation game also performed better with an increased number of users in the network because of the effective coordination offered by the algorithm.Keywords— Cellular, coalition game, D2D, overlay, spectrum.

Published: September 2020

Latent heat storage in salt mixture has drawn so much attention because of the salt mixture’s capability of storing large quantity of heat when compared to single salt thereby, making it more feasible for use as phase change material. However it is worthwhile to find out among various combination of salts forming eutectic mixtures, the one that has the best energy storage capability by evaluating and comparing their melting points and latent heat storage. So in this research work, four different types of eutectic mixture of salts were prepared and experimentally investigated for the best thermal energy storage capability. The first eutectic mixture consists of 2.6g of LiNO3, 6.4g of NH4NO3 and 1g of NaNO3. The second eutectic mixture consists of1.75g of LiNO3, 3.9g of NH4NO3 and 1.1g of KNO3. The third one consists of 5.2g of LiNO3, 13.7g of NH4NO3 and 1g of NH4Cl) and the fourth one consists of 1.77g of LiNO3, 2.94g of NH4NO3, 1g of NaNO3 and 1g of NaCl. The latent heat and the melting point of the respective salt and their eutectic mixture were determined using digital differential scanning Apparatus. The results obtained showed that the melting points and latent heats of the first, second, third and fourth eutectic mixture were 79.50C and 112kJ/kg, 80.50C and 114kJ/kg, 81.40C and 109kJ/kg, 84.40C and 119kJ/kg respectively. In view of this, the eutectic mixture of 1.77g of LiNO3, 2.94g of NH4NO3, 1g of NaNO3 and 1g of NaCl with melting point of 84.40C and latent heat of 119KJ/Kg was found to possess the best thermal energy storage capability compared to others..Keywords—Eutectic mixture, Salts, Phase change materials (PCM), Latent heat storage

Published: September 2020

The research work investigates the corrosion resistance of Silver-Cobalt Oxide-Titanium Dioxode (Ag/Co3O4/TiO2) nanocomposites coated mild steel (AISI 1020) in seawater environment. The coatings were carried out by dipping method. The nanoparticles were individually produced by mixing the salt precursors with extract of Piptadeniastrum africana leaf under the optimized synthesis conditions. The Ag/Co3O4/TiO2 nanocomposite was produced by mixing Ag, Co3O4 and TiO2 NPs in equal proportions to constitute 75 wt% of the composite. 10 wt % epoxy resin and its hardener in the ratio (1:1) were added to serve as the binder, while 15 wt% of CNT was introduced to serve as support. Phase and Microstructural examination of the coatings was carried out by XRD and HRSEM. The corrosion protection properties were determined by using computer- controlled EGG 273A Potentiostat with three- electrode cell system under static laboratory conditions using the linear potentiodynamic polarization method. The coated sample was dried at temperatures of 100oC to enhance adherence of the coating on the steel substrate. The result of Tafel polarization plots revealed improved corrosion resistance of the coated specimen as compared to as-received sample. Corrosion rate and corrosion resistance of 0.201 m/y and 195.12 Ω were recorded against the coated sample while 0.261 m/y and 71.42 Ω were recorded for the as-received sample respectively. The coated sample exhibited higher potential shift in the positive direction and showed better corrosion resistance properties.Keywords- Nanocomposite, Mild steel, Corrosion, Potentio-Dynamic polarization, Seawater.
