Published: October 2019

Grant scholarships to students are conducted by the University based on the achievements achieved. Since the last few years Bhayangkara University has run a Joint Degree Program scholarship in cooperation with Thailand, India, and plans to continue to the Netherlands. In scholarship grants, the Universityoften finds it difficult to determine the scholarship recipients, so it is found that scholarships are not accurate due to the manual system for the awarding of scholarships. The decision support system is an information system aimed at assisting the University in solving the problem of awarding Joint Degree Program scholarship. One method that can be used in decision support systems is Analitycal Hierarchy Process (AHP). The Analytical Hierarchy Process (AHP) method takes into account the extent of validity to the extent of inconsistency tolerance of the various criteria and alternatives chosen by the decision maker. In this research, the data used is UBHARA student data 3 last generation. The criteria used are GPA, TOEFL score, TPA Test Score, and Value of Communication Skill Test. From the results of experiments carried out the results of manual calculations of the application and manual calculations from the Institute of Cooperation get a presentation 100% equation in determining scholarship recipients. So as to produce the ranking of students, two students with the highest score in each department that will get a Joint Degree Program scholarship.Keywords: Scholarship, Student, Analytical Hierarchy Process (AHP), Decision Support System.

Published: October 2019

In the countries of southern Europe, the economic adjustment policies being applied are causing a progressive weakening of the museological action in its various forms. Questioned within the transformation process involving a profound change of the management models and of the prevailing values, museums seek a Sustainable Museology.

In this context, new museological formulas emerge associating sustainability to social creativity and to valorization of diversity. This is the case of the Costume Museum in São Brás de Alportel (MuT), in the Algarve, and its "Museology on layers". A model based on shared management, taking as its starting point a deep knowledge of the territory, the collective construction of senses and local cultural meanings, and the reframing of ancestral knowledge, with the objective of contributing to an equitable development.

In this paper we present the structure, the method and the results of one of the reference projects: Photography, memory and identity (FMId). In this case, a contrastive analysis between the collaborative research and the cartography of meanings associated with pictures of each family is performed. This exercise of memorial archaeology leads to decoding diverse segments of local culture. Its resonances reach every one of the museological functions and processes of MuT, but also each of the families involved in the project, have now a current account of memory in their hometown Museum.

IMPACT OF THE INFLATION PRESSURE OF THE TIRES ON LEAD OF FRONT DRIVE WHEELS AND MOVEMENT RESISTANCE FORCE OF TRACTORS
Authors: Janulevičius Algirdas , Gurevičius Povilas
Published: October 2019

The transmission of mechanical front-wheel drive tractors normally has a front axle lead ratio, which is equal to 1.5…2.5%. Naturally, when ballast masses are added to the tractor or when inflation pressure in the tires is reduced, distortion of the tires is inevitable, which changes the lead of the front wheels. In this paper, we present the impact of tire inflation pressures on the lead front drive wheels and movement resistance force when the tractor travelled with a front drive axle enabled and was engine braking with the fuel supply off. It was found that the variation in front and rear tires inflation pressure combination can significantly change the lead of the front drive wheels. For the tested tractor up to 6.9%. The result is that when the tractor travelled with the front axle enabled and was engine braking, the engine-braking efficiency decreases with increasing lead of the front wheels. Front (slipping) wheels create the opposite-direction torque, which is transferred to the rear wheels through the tractor’s front-rear axle drive system. Additional losses of the engine braking occur in transmission due to power circulation, and the result is that the tractor wheels receive less braking torque from the engine.
S and VV Corona Australis: Spectroscopic Variability in Two Young Binary Star Systems
Authors: Sullivan Kendall , Prato L. , Edwards Suzan , Avilez Ian , Schaefer Gail H.
Published: October 2019

We used high-resolution near-infrared spectroscopy from the NIRSPEC instrument on the Keck II telescope, taken over multiple epochs spanning five years, to examine two young binary T Tauri star systems, S Corona Australis and VV Corona Australis. The stars in these 1″–2″ separation systems have optically thick circumstellar disks and high extinctions at optical and near-infrared wavelengths. Using a combination of new and archival data, we have determined the spectral types of all of the stars in these two systems for the first time, examined the variable NIR veiling, measured the emission line equivalent widths, and created spectral energy distributions. They have similar spectral types (K7-M1) and are at approximately the same evolutionary stage, allowing for comparison of the four stars in the two systems. We conclude that S CrA and VV CrA are young binary systems of stars bridging the Class I and Class II evolutionary stages, characterized by high accretion luminosities and variable emission lines.

Temperature dependence of the heat capacity and change in the thermodynamic functions of strontium-alloyed AK1M2 alloy
Authors: Ganiev Izatullo N. , Otajonov Suhrob E. , Ibrohimov Nasim F. , Mahmudov M.
Published: October 2019

The temperature dependence of the specific heat capacity and change in the thermodynamic functions of strontium-alloyed ultrahigh-purity aluminum base AK1M2 alloy have been studied in “cooling” mode over the 298.15–900 K range. Mathematical models describing the evolution of these properties of the alloys in the abovementioned temperature range with change in alloying addition concentration have been obtained. The heat capacity, enthalpy and entropy of the alloys increase with temperature, decrease with an increase in the alloying addition concentration to 0.5 wt.% and grow with a further increase in the alloying addition concentration. The Gibbs energy of the alloys has an inverse dependence: it decreases with an increase in temperature and grows with an increase in the alloying addition concentration to 0.5 wt.%.
First mitochondrial genome from Yponomeutidae (Lepidoptera, Yponomeutoidea) and the phylogenetic analysis for Lepidoptera

Published: October 2019

The complete mitochondrial genome (mitogenome) of Yponomeuta montanatus is sequenced and compared with other published yponomeutoid mitogenomes. The mitogenome is circular, 15,349 bp long, and includes the typical metazoan mitochondrial genes (13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes) and an A + T-rich region. All 13 protein-coding genes use a typical start codon ATN, the one exception being cox1, which uses CGA across yponomeutoid mitogenomes. Comparative analyses further show that the secondary structures of tRNAs are conserved, including loss of the Dihydorouidine (DHU) arm in trnS1 (AGN), but remarkable nucleotide variation has occurred mainly in the DHU arms and pseudouridine (TψC) loops. A + T-rich regions exhibit substantial length variation among yponomeutoid mitogenomes, and conserved sequence blocks are recognized but some of them are not present in all species. Multiple phylogenetic analyses confirm the position of Y. montanatus in Yponomeutoidea. However, the superfamily-level relationships in the Macroheterocera clade in Lepidoptera recovered herein show considerable difference with that recovered in previous mitogenomic studies, raising the necessity of extensive phylogenetic investigation when more mitogenomes become available for this clade.

Les racines de la violence
Authors: Denis Paul
Published: October 2019

La notion de violence en psychopathologie renvoie avant tout à la quantité de l’excitation en jeu. Envisager la violence à l’adolescence revient donc à considérer ce qui bouleverse l’économie de l’adolescent au point de déborder ses ressources psychiques. C’est à cette période de la vie la conjonction de sources d’excitations internes et de stimulations excessives, alors que l’investissement des relations aux parents n’a plus le même rôle économique, qui fait le « traumatisme de l’adolescence ».

La violence comme réponse aux frontières du symbolique
Authors: Tiscini Giorgia , Kalaora Léa
Published: October 2019

L’objectif de cet article est de conceptualiser le phénomène de la violence par une méthode mixte : la révision historique et littéraire s’accompagne d’une méthodologie clinique. L’hypothèse démontrée est que la violence réside à l’interstice entre sujet et social, et émerge des failles du système symbolique, comme dans le cas de l’adolescence, du crime et de la « folie ». Le travail sur la violence, en tant que réponse à ce qui demeure hors symbolique, vise alors le sen , pour que la violence de l’un ne devienne pas celle de tous.

Les graines de la violence

Published: October 2019

Le concept d’ adolescent difficile permet de sortir du piège nosographique consistant à rejeter les causes de la violence sur son seul auteur. La dimension du lien offre une analyse complexe et critique des déterminants environnementaux, notamment institutionnels, de la violence. En évacuant la relation, des gouvernances institutionnelles contribuent à réifier le sujet, vulnérabilisant les publics comme les professionnels. Sécrétrices de violence, les institutions la récolteraient ainsi en retour.

Résumé L'alternative entre légitimité et efficacité a été, dans les années 2000, non seulement au c ur du débat sur le multilatéralisme, mais aussi un des moteurs de l'évolution de la pratique multilatérale. Des formes plus restreintes, informelles, flexibles et réactives de coopération internationale sont ainsi apparues comme une réponse à l'inefficacité présumée d'un multilatéralisme plus institutionnel. Pourtant, l'efficacité de l'action collective a plus à gagner d'une articulation entre ces différents formats que de leur opposition. À l'inverse, opposer légitimité et efficacité semble jouer contre l'idée même d'un ordre multilatéral, aujourd'hui de plus en plus contesté.
Un modèle industriel gagnant pour la défense européenne

Résumé Les programmes capacitaires en coopération se sont développés depuis quatre décennies, en raison du coût de développement des projets les plus ambitieux. Ils vont prendre une ampleur nouvelle grâce aux initiatives lancées dans la défense au niveau communautaire depuis 2016. Conduisant à une gouvernance hybride entre États et Commission européenne, le modèle des coopérations réussies, notamment en matière de missiles, permettrait de mettre à profit ces initiatives pour renforcer l'autonomie stratégique européenne. Ces programmes favoriseront l'intégration transnationale des bases industrielles en Europe, condition préalable à toute coopération transatlantique équilibrée et à l'efficacité des dépenses de défense en Europe.
Waldam 3 (Marck, Pas-de-Calais) : un navire de commerce échoué au tournant des XVIII e et XIX e s
Authors: Sauvage Cécile , Dieulefet Gaëlle , Rieth Eric , Tachet Nicolas , Jaouen Marine
Published: October 2019

Le site baptisé Waldam 3, situé sur l’estran à Marck (Pas-de-Calais) est découvert au printemps 2014 à la faveur du désensablement de la plage. Il prend alors la forme d’un amoncellement de galets, tessons de verre et de céramique, au sein duquel sont prélevés quelques artefacts plus complets. Après une rapide expertise, qui permet de confirmer l’intérêt du site et du mobilier, une opération de sondage est programmée à la faveur des grandes marées du mois d’avril 2015. Il s’agit d’identifier d’éventuels vestiges de coque et de qualifier l’intérêt archéologique du gisement. Le mobilier préservé comble en partie le manque d’informations induit par l’absence de structure navale et permet d’avancer des hypothèses quant à la nature et à la chronologie du site. Les cinq fragments de bordages découverts indiquent que nous sommes en présence des restes d’une épave de navire dont le tonnage pourrait être compris entre 150 et 250 tonneaux. La présence d’un octant renvoie à un bateau destiné à la navigation hauturière et le mobilier céramique tend à indiquer un navire de commerce doté d’une petite cargaison. L’étude du mobilier permet également de montrer que le navire a fait naufrage entre 1787 et les années 1810. Par ailleurs, le faciès global du mobilier encourage à interpréter le site comme un navire provenant des îles britanniques. La comparaison avec les mentions de naufrage connues dans les archives permet de proposer, à titre d’hypothèse, plusieurs candidats pour l’identification de l’épave Waldam 3.

A Deployable Brace Model with Joint Clearance and Strut Eccentricity in Seismic Design
Authors: Hu Ming Hao , Yang Pu , McCrum Daniel
Published: October 2019

The paper discusses seismic performance of deployable brace member as well as its application in single-story single-bay frame by using finite element method in OpenSees Navigator. Even though deployable structure has wide applications in engineering area, it is almost blank for earthquake (seismic) engineering. A finite element deployable brace model consisting two identical struts and a revolute joint is built in this paper. The model considers joint clearance and initial eccentricity to accord practical situation. Hysteresis analysis has been done on the brace model as well as its application. The results show deployable structure provides sufficient lateral stiffness and ductility. Strut eccentricity is the key factor affecting the capacity of the strut and buckling strength, while joint clearance also has influence on the strut capacity and energy dissipation.
Evaluation for RC Column Confined Partially with Externally FRP Wrapping Sheet Using Nonlinear FE Analysis
Authors: Obaidat Yasmeen Taleb
Published: October 2019

Little research has been carried out in validating, fiber reinforced polymer (FRP) concrete strengthened column and the effective using partial wrapping. Also the effect of several parameter on strengthen column using the partial wrapping sheet of desired width and thickness around column have not been found out. To this end, a nonlinear 3D finite element model has been developed in current study for CFRP strengthened reinforced concrete column to simulate the behavior accompanied by the effect of partial wrapping with emphasis on load capacity and failure mode. The finite element simulation of CFRP strengthened RC columns is performed using commercial finite element program ABAQUS. Modelling was conducted on reinforced concrete columns with dimensions of 160 x 250 x 960 mm. The finite element model incorporates the nonlinear material behavior of concrete, bilinear stress-strain curve of steel and linear elastic behavior of CFRP material. The concrete was modeled using a plastic damage model. The performance of the FE model was studied by simulating experimental columns from the literature. The load, and strain of CFRP obtained from the FE study were compared with the corresponding experimental results. The FEM results agreed well with the experiments. In addition, to enhance our understanding of the behavior of strengthened reinforced concrete column capacity using partial wrapping the effect of changing the spacing between the CFRP sheets and number of layers were examined. The increase number of layers and decrease spacing give a higher ultimate load capacity, and delay the failure.
Mechanical Behaviour of Composite Material Based on Mortar/Natural Fibers (Fique "Furcraea andina") Meshes as External Reinforcement of Concrete Beams
Authors: Puentes Alvaro , Soto José , Díaz-Ramírez Germán , Hernández Ricardo Cruz
Published: October 2019

This work shows the effect of an external reinforcement of concrete beams using a composite material based on woven meshes obtained from natural fibers of fique "furcraea andina" embedded in a Portland cement mortar. Fique is an endemic plant of the Colombian Andean region. The woven meshes tensile resistance was obtained according to the ASTM D-5034 standard. Flat orthogonal woven meshes were characterized, made with 714.3 tex linear density yarns, separated 3, 5 and 8 mm in warp and weft directions, likewise, the concrete beams rupture module was evaluated according to the ASTM C78 standard. Beams were tested, both without mesh reinforcement and with external reinforcement. Beams were reinforced on one, three and four of their faces. A commercial epoxy adhesive was used to glue the composite material to the concrete beams and their behaviour were tested with and without the application of the epoxy. The four faces reinforced composite beam showed an increase of 80% of its bending resistance compared to the beam without any additional reinforcement, showing a greater ductility and better mechanical behaviour. The results of this study demonstrate the effectiveness of the use of fique meshes as alternative reinforcement agents for cementitious compounds in structural elements, opening the way for future investigations into the use of natural fibers in construction alternative materials.
A Study on the Effect of Argon-Oxygen Plasma Treatment on Ultra-Thin Expanded PTFE Membrane
Authors: Nishiguchi Naomi R. , de Yro Persia Ada N.
Published: October 2019

Polymer films are plasma treated to improve surface properties making them hydrophilic or hydrophobic. Expanded polytetrafluoroethylene (ePTFE) is used in a wide variety of applications but only a few report on plasma treated ePTFE. Within these very few studies on ePTFE, the use of ultra-thin membrane could hardly be found. The purpose of this study is to investigate the effect of plasma treatment (Argon-Oxygen) on the hydrophobicity of ultra-thin ePTFE membrane (4um thickness). This study used nine (9) experimental legs of ePTFE subjected to respective plasma power (150W, 315W and 600W) and exposure time (300s, 450s and 600s) for each leg. Contact angle was measured prior and after subjecting to plasma condition using contact angle meter. Energy pen was also used to verify its hydrophobicity. Scanning electron microscopy (SEM) with 10,000x magnification was used to check for any change in surface after exposing to each condition. The findings showed that the membrane surface changed after exposure to plasma. All legs became hydrophilic. 102◦ contact angle was measured from raw sample, but the samples exposed to plasma had contact angles ranging from max of 68◦ to min of 48◦. The results showed that the degree of surface change could be correlated to the plasma parameters applied. Furthermore, the highest radio frequency (RF) power applied resulted to contact angle in the range of 60◦ while the lowest RF power applied resulted to the lowest contact angle, in the range of 40◦, measured. On the other hand, no particular trend was observed based on exposure time. Based on the gathered results, the ultra-thin ePTFE, in order to maintain its hydrophobicity, must not be applied with argon-oxygen plasma treatment. However, if the ultra-thin ePTFE is to be made hydrophilic, argon-oxygen plasma treatment could be applied while adjusting the plasma parameters to meet the desired hydrophilicity level.
Anti-Counterfeiting Layer of 2D Colloidal Crystal Based Photonic Material
Authors: Chen Cheng , Wang Xiao Hui , Dong Zhi Qiang , Chen Gong , Han Lu Xiao , Zhu Zhi Gang
Published: October 2019

A facile approach of robust polymer-based two-dimensional (2D) colloidal crystal (CC) layers was presented. This technology enables the convenient fabrication of an anti-counterfeiting coating with a polymeric 2D CC, allowing the fast preparation of functional polymer photonic materials. Briefly, a 2D CC was prepared by self-assembly of polystyrene (PS) submicrospheres, which was then transferred to substrates by adhesive polymeric solution and cured to form a photonic film. Such photonic films strongly and angle dependently diffract visible light, and the high transparency of the photonic layers ensured the readout from the substrate. The PC layers can also prevent the re-write or re-print on the substrate, indicating the potential applications in colorful and anti-counterfeiting coating materials.

Published: October 2019

In recent years, Al-5Mg alloy thermal spray coatings have been used as an anti-corrosion coating applied for various components of steel structures, in some cases it was covered by the conventional heavy-duty coating. However, the deterioration characteristics of overlapping layers between thermal spray layer and heavy-duty paint coating still not clear. In this study, to compare the anti-corrosion characteristics of the single thermal spray coating and overlapping layers, the accelerated cyclic exposure tests were carried out on specimens with three types of coating layers. To clarify the deterioration characteristics, the cross-cut defect were introduced into specimens, and the EIS measurements, glossiness test, EPMA elemental analyses were conducted on test specimens. The test results indicated that the deterioration of the overlapping layer at the steel base-exposed portion occurs earlier than the case of Al-5Mg thermal spray coating. In addition, the deterioration of thermal spray coating was accelerated by the sealing treatment in specimen with overlapping layers.

Published: October 2019

In the case of exposure of reinforced concrete structure to accidental fire, an assessment of its residual capacity is needed. Bond strength of concrete was observed under elevated temperatures (150°, 250°, 350° and 500°C) in this study. Cylindrical specimens were prepared for pull-out tests to find out the bond behavior and to observe the mechanical properties of concrete. All the specimens were 100 mm diameter and 200 mm height. The pull-out specimens contain a 10 mm steel bar at its center. The specimens were tested at 52 days age following a 28 days water curing. Samples were preheated for 3 hours at 100°C temperature and then put into the furnace for 1 hour at the target temperature. Samples were tested before preheating as controlled specimens. In case of mechanical properties and the bond strength of concrete, there were no remarkable changes due to elevated temperature up to 150°C. However, the mechanical properties and bond strength were decreased gradually after 150°C temperature. Maximum reduction of bond strength observed was 52.13% and 49.8% at 500°C for testing within 1 hour and after 24 hours of heating respectively when compared to the controlled specimens. Bond strength was found to reduce at a greater rate than compressive strength due to the elevated temperature.
Bond Behavior of Low-Activated High Aluminate Concrete with Reinforcement under Cyclic Load
Authors: Kan Yu Cheng , Pei Kuang Chih , Hsu Wei Lin
Published: October 2019

The bond behavior of reinforcement and low-activated concrete (LAC) was investigated in this study. The acoustic emission monitoring was also engaged while the specimen being loaded to figure out the inside fracture. Static loading and dynamic loading were applied for both of the LAC and normal concrete in the pull-out tests. The upper load was applied starting from 30% of the static ultimate load Pu with a 10% increment until the failure. The loading frequencies for the test were 0.5 Hz、1.0 Hz and 2.0 Hz. The bond stiffness after each stage of dynamical loads was examined. Test results reveal that the LAC performs higher compressive strength than normal concrete for a given W/C ratio. But, the bond strength of LAC seems not promotes correspondingly. It may be attributed to the conversion effect of high alumina contained in LAC, which leads to more voids inside the concrete.

The inflammasomes play critical roles in numerous pathological conditions largely through IL-1β and/or IL-18. However, additional effectors have been implied from multiple studies. In this study, through two independent mass spectrometry–based secretome screening approaches, we identified galectin-3 as an effector protein of the NLRP3 inflammasome. Although the activation of AIM2 or NLRC4 inflammasome also led to galectin-3 secretion, only the NLRP3 inflammasome controlled the serum galectin-3 level under physiological condition. Mechanistically, active gasdermin D drove the nonexosomal secretion of galectin-3 through the plasma membrane pores. In vivo, high-fat diet–fed Nlrp3−/− mice exhibited decreased circulating galectin-3 compared with wild-type animals. Of note, the improved insulin sensitivity in such Nlrp3−/− mice was aggravated by infusion of recombinant galectin-3. Moreover, galectin-3 was essential for insulin resistance induction in mice harboring the hyperactive Nlrp3A350V allele. Thus, the inflammasome–galectin-3 axis has been demonstrated as a promising target to intervene inflammasome and/or galectin-3 related diseases.

Infection with Listeria monocytogenes is acquired through ingestion of contaminated foods and may lead to systemic infection and possible death, with an overall 20% mortality rate. Our previous work using C5aR1−/− mice and C3aR−/− mice demonstrated that C5aR1 and C3aR both play powerful anti-inflammatory and prosurvival roles during systemic infection with L. monocytogenes. In our current study, we have examined the role of the third anaphylatoxin receptor, C5aR2, in the host immune response to systemic L. monocytogenes infection. C5aR2−/− mice had significantly lower bacterial burdens in the spleens and livers on both day 1 and 3 postinfection compared with C5aR2+/+ mice. The decreased bacterial burdens in the C5aR2−/− mice correlated with less liver damage and with improved survival of CD4+ and CD8+ T cells in the spleen on day 3 postinfection compared with C5aR2+/+ mice. C5aR2−/− mice also produced significantly less G-CSF, IL-6, and MCP-1 in the serum, spleen, and liver on day 1 postinfection compared with C5aR2+/+ mice. C5aR2−/− and C5aR2+/+ mice produced similar amounts of IFN-γ in their spleens on day 1 postinfection. Purified naive splenocytes from C5aR2−/− mice produced significantly more IFN-γ and IL-12p70 during in vitro infection with L. monocytogenes compared with splenocytes from C5aR2+/+ mice in an NF-κB–dependent manner. Induction of IL-12 and IFN-γ early during infection with L. monocytogenes is protective to the host, and we believe this innate increased ability to produce more IL-12 and IFN-γ provided early protection to the C5aR2−/− mice.

Neonates often develop poor immunity against intracellular pathogens. Because CD8+ T cells are essential for eliminating infectious agents, it is crucial to understand why they behave differently in early life. Previous studies in mice have demonstrated that neonatal CD8+ T cells fail to form memory because of an intrinsic propensity to differentiate into short-lived effectors. However, the underlying mechanisms remain undefined. We now show that neonatal CD8+ T cells exhibit higher glycolytic activity than adult CD8+ T cells postinfection, which may be due to age-related differences in Lin28b expression. Importantly, when glycolysis is pharmacologically inhibited, the impaired formation of neonatal memory CD8+ T cells can be restored. Collectively, these data suggest that neonatal CD8+ T cells are inherently biased toward undergoing glycolytic metabolism postinfection, which compromises their ability to develop into memory CD8+ T cells in early life.
Street knowledge. Stories, codes and street life
Authors: Landi Andrea
Published: October 2019

This work, besides making a careful examination, represents a real journey inside of a world that has gone through times and places, broke patterns of the past to live without, has undergone changes and revolutions, has known love to destroy hatred, is the knowledge of the movement, the movement of the body and mind ... is the hip hop!! The word "hip hop" contains the term "movement", that it is not only part of its meaning, but is what it represents. The hip hop, in fact, is born and begins to move from a road, or rather from a more restricted and circumscribed place, a house in the neighborhood between you forgotten and abandoned, the Bronx, to spread and take over the entire world. The importance of this phenomenon resides in the factor, that in the early 70s its creators and founders were all teenagers. The world of hip hop, which now affects and imposes itself in the world of fashion, music, language and society, was founded by young people. The hip hop was born from young adolescents of New York and took the world by storm. Over the years he has found a way to break down the barriers that surrounded him, being able to fit into so universal culture and to influence it and change it profoundly. It changed the way we live and stand in the street: from clashes and territories conquests, to a no more shots of gunfire, but sound of scratch and spray. It moved the people making them move and do not die. It moved crew and no gang. It moved minds to create and invent steps, rhymes and lines. It moved fashions, cultures and thoughts uniting and not dividing them. This journey from the gang to the crew begins by providing the reading and analysis keys with which is possible understand and thoroughly investigate birth, origin, causes and evolution of the gang going from New York suburbs up to the main Italian cities. The route continues by examining how many of these gangs have abandoned the path of violence undertaking a new way of re-socialization through the hip hop culture and how this phenomenon is rooted in the world. Through calligraphic analysis, interviews with writers, life stories of street people and contributions on DJing and legality, the journey ends interpreting and expressing the thoughts on the studies and on the investigations examined.
The testimony of a minor: when does a procedural truth correspond to a historical truth?
Authors: Marra Luisa
Published: October 2019

The child abuse in its various forms, physical, sexual and psychological violence, is a complex phenomenon, potentially able to alter not only the natural development of the subject abused, but also his ability to relate to others. This paper aims to point out the way that the child has to take from the moment he decided to take over being a victim of abuse at the time when it is called to testify about the abuse right away, with all the difficulties that this witness implies, not only for the child himself, but also for those who are called upon to decide and rule on the quality of that testimony. The art. 196 of the current Code of Criminal Procedure recognizes everyone the ability to testify, then, including minors. Nothing therefore prevents the operators from taking information from a child in criminal trials. Moreover, investigators have wide discretion not only "if" hearing the minor, but also on the methods to do it. This entails serious risks on the authenticity of the evidential result: mnestic lability, suggestibility, tendency to pander to the interlocutor's expectations, all of which are typical factors of the minor that can compromise the correct reconstruction of the facts.

Published: October 2019

Rift Valley fever (RVF) is a zoonotic viral disease caused by the RVF phlebovirus (RVFV) that infects a variety of animal species including sheep and goats. Sera (n = 893) collected between 2013 and 2015 from randomly selected indigenous sheep and goats in seven provinces of the Democratic Republic of the Congo (DRC) were tested for the presence of specific immunoglobulin G (IgG) and M (IgM) against RVFV, using two commercially available enzyme-linked immunosorbent assays. The reverse transcription polymerase chain reaction (RT-PCR) was also used to detect RVFV nucleic acid. There was significant variation in true seroprevalence of RVFV for both sheep and goats between the seven provinces investigated. Values ranged from 0.0 (95% confidence interval [CI] 0.0–6.55) to 23.81 (95% CI 12.03–41.76) for goat and 0.0 (95% CI 0.0–7.56) to 37.11 (95% CI 15.48–65.94) for sheep, respectively. One serum (1.85%) out of 54 that tested positive for IgG was found to be IgM-positive. This same sample was also positive by RT-PCR indicating an active or recent infection. These findings report the presence of RVFV in small ruminants in the DRC for the first time and indicate variations in exposure to the virus in different parts of the country.
Food and Fuel Prices-Recent Developments, Macroeconomic Impact, and Policy Responses—An Update
Authors:   International Monetary Fund
Published: October 2019

This report updates the macroeconomic assessment of the impact of global food and fuel price increases provided in the IMF June 2008 Board paper: Food and Fuel Prices—Recent Developments, Macroeconomic Impact, and Policy Response. Food and oil prices peaked in early summer—in particular, oil prices surged to levels envisaged under the most adverse scenario presented in the June paper. Against this background, the effects of higher prices on the balance of payments, budgets, and domestic prices intensified and a large group of low- and middle-income countries is experiencing a substantial weakening of their balance of payments and higher inflation. These findings reinforce the importance of adopting appropriate policies to maintain macroeconomic stability while protecting the poor.
Wavelet analysis of the magnetotail response to solar wind fluctuations during HILDCAA events

Published: October 2019

Abstract. In this work a study of the effects of the high-intensity
long-duration continuous AE activity (HILDCAAs) events in the magnetotail
was conducted. The aim of this study was to search the main frequencies
during HILDCAAs in the Bx component of the geomagnetic field in the
magnetotail, as well as the main frequencies, at which the magnetotail
responds to the solar wind during these events. In order to conduct this
analysis the wavelet transform was employed during nine HILDCAA events that
coincided with Cluster spacecraft mission crossing through the tail of the
magnetosphere from 2003 to 2007. The most energetic periods for each event
were identified. It was found that 76 % of them have periods ≤4 h. With the aim to search the periods that have the highest
correlation between the IMF Bz (OMNI) component and the Cluster Bx
geomagnetic field component, the cross wavelet analysis technique was also
used in this study. The majority of correlation periods between the Bz (IMF)
and Bx component of the geomagnetic field observed also were ≤4 h,
with 62.9 % of the periods. Thus the magnetotail responds stronger to IMF
fluctuations during HILDCCAS at 2–4 h scales, which are typical substorm
periods. The results obtained in this work show that these scales are the
ones on which the coupling of energy is stronger, as well as the modulation
of the magnetotail by the solar wind during HILDCAA events.
