Centralized or Decentralized Rainwater Harvesting Systems: A Case Study
Authors: Słyś Daniel , Stec Agnieszka
Published: January 2020

World population growth, climate changes, urbanization, and industrialization have all had a negative impact on natural resources, including water resources. Excessive exploitation and pollution have caused more and more regions to have problems with access to fresh water. Rainwater is perceived as a valuable alternative source of water that is most often used in a hybrid system supplementing tap water. Considering the possibilities of designing a rainwater harvesting system as a decentralized or central system, this research was undertaken to determine the hydraulic and financial efficiency of these two systems. The research was carried out for a single-family housing estate located in Poland. For this research, a simulation model was applied to determine the efficiency of water saving and the life cycle cost indicator. In variants where rainwater was only used to flush toilets, the water saving efficiency was 80% and 79% for the decentralized and centralized rainwater harvesting system (RWHS), respectively. The use of rainwater for toilet flushing and watering the garden resulted in a significant reduction in efficiency to 57% (the decentralized system) and 54% (the centralized system). On the other hand, the results of the life cycle cost (LCC) analysis showed that in spite of reducing tap water consumption, both the centralized and the decentralized rainwater harvesting system were not financially viable solutions for the housing estate, and only cofinancing investments at the level of 25% to 50% resulted in a significant improvement in financial efficiency.

Published: January 2020

Air quality in urban environments has become a central issue of our present society as it affects the health and lives of the population all over the world. The first step in mitigating negative effects is proper measurement of the pollution level. This work presents a portable air pollution measurement system, built from off-the-shelf devices, that is designed to assure user privacy and data authenticity. Data is collected from sensor modules that can be hand carried or installed on vehicles, possibly leading to a vehicular sensor network that may cover a larger area. The main challenge is to provide authenticity for the sensor data while also ensuring user privacy. The proposed system assures authenticity and non-repudiation for the collected data by using group signatures and a blockchain-like structure for secure storage. We use regular key-exchange protocols based on elliptic curve cryptography in order to securely bootstrap a session key, then we benefit from secure tunneling to export data from sensors to the remote server. Post-update tampering is prevented by the use of a blockchain-like structure on the data server. We carry experiments both to determine the computational requirements of the procedures, as well as to measure indicators of air quality on nearby areas.
Design of Resistor-Capacitor Physically Unclonable Function for Resource-Constrained IoT Devices
Authors: Lee Sangjae , Oh Mi-Kyung , Kang Yousung , Choi Dooho
Published: January 2020

Keeping IoT devices secure has been a major challenge recently. One of the possible solutions to secure IoT devices is to use a physically unclonable function (PUF). A PUF is a security primitive that can generate device-specific cryptographic information by extracting the features of hardware uncertainty. Because PUF instances are very difficult to replicate even by the manufacturer, the generated bit sequence can be used as cryptographic keys or as a unique identifier for the device. Regarding the implementation of PUF, the majority of PUFs introduced over the past decade are in the form of active components and have been implemented as separate chips or embedded as a part of a chip, making it difficult to use them in low-cost IoT devices due to cost and design flexibility. One approach to easily adopt PUFs in resource-constrained IoT devices is to use passive components such as resistors and capacitors (RC) that can be configured at low cost. The main feature of this RC-based PUF is that it extracts the small difference caused by charging and discharging of RC circuits and uses it as a response. In this paper, we extend the previous research and show the possibility to secure IoT devices by using the RC-based PUF.
Experimental Study of Visual Corona under Aeronautic Pressure Conditions Using Low-Cost Imaging Sensors
Authors: Riba Jordi-Roger , Gómez-Pau Álvaro , Moreno-Eguilaz Manuel
Published: January 2020

Visual corona tests have been broadly applied for identifying the critical corona points of diverse high-voltage devices, although other approaches based on partial discharge or radio interference voltage measurements are also widely applied to detect corona activity. Nevertheless, these two techniques must be applied in screened laboratories, which are scarce and expensive, require sophisticated instrumentation, and typically do not allow location of the discharge points. This paper describes the detection of the visual corona and location of the critical corona points of a sphere-plane gap configurations under different pressure conditions ranging from 100 to 20 kPa, covering the pressures typically found in aeronautic environments. The corona detection is made with a low-cost CMOS imaging sensor from both the visible and ultraviolet (UV) spectrum, which allows detection of the discharge points and their locations, thus significantly reducing the complexity and costs of the instrumentation required while preserving the sensitivity and accuracy of the measurements. The approach proposed in this paper can be applied in aerospace applications to prevent the arc tracking phenomenon, which can lead to catastrophic consequences since there is not a clear protection solution, due to the low levels of leakage current involved in the pre-arc phenomenon.
Cognitive Frequency-Hopping Waveform Design for Dual-Function MIMO Radar-Communications System
Authors: Yao Yu , Li Xuan , Wu Lenan
Published: January 2020

A frequency-hopping (FH)-based dual-function multiple-input multiple-output (MIMO) radar communications system enables implementation of a primary radar operation and a secondary communication function simultaneously. The set of transmit waveforms employed to perform the MIMO radar task is generated using FH codes. For each transmit antenna, the communication operation can be realized by embedding one phase symbol during each FH interval. However, as the radar channel is time-variant, it is necessary for a successive waveform optimization scheme to continually obtain target feature information. This research work aims at enhancing the target detection and feature estimation performance by maximizing the mutual information (MI) between the target response and the target returns, and then minimizing the MI between successive target-scattering signals. The two-step cognitive waveform design strategy is based upon continuous learning from the radar scene. The dynamic information about the target feature is utilized to design FH codes. Simulation results show an improvement in target response extraction, target detection probability and delay-Doppler resolution as the number of iterations increases, while still maintaining high data rate with low bit error rates between the proposed system nodes.
Dynamic Model and Inverse Kinematic Identification of a 3-DOF Manipulator Using RLSPSO
Authors: Batista Josias , Souza Darielson , dos Reis Laurinda , Barbosa Antônio , Araújo Rui
Published: January 2020

This paper presents the identification of the inverse kinematics of a cylindrical manipulator using identification techniques of Least Squares (LS), Recursive Least Square (RLS), and a dynamic parameter identification algorithm based on Particle Swarm Optimization (PSO) with search space defined by RLS (RLSPSO). A helical trajectory in the cartesian space is used as input. The dynamic model is found through the Lagrange equation and the motion equations, which are used to calculate the torque values of each joint. The torques are calculated from the values of the inverse kinematics, identified by each algorithm and from the manipulator joint speeds and accelerations. The results obtained for the trajectories, speeds, accelerations, and torques of each joint are compared for each algorithm. The computational costs as well as the Multi-Correlation Coefficient ( R 2 ) are computed. The results demonstrated that the identification accuracy of RLSPSO is better than that of LS and PSO. This paper brings an improvement in RLS because it is a method with high complexity, so the proposed method (hybrid) aims to improve the computational cost and the results of the classic RLS.
City-Wide Traffic Flow Forecasting Using a Deep Convolutional Neural Network
Authors: Sun Shangyu , Wu Huayi , Xiang Longgang
Published: January 2020

City-wide traffic flow forecasting is a significant function of the Intelligent Transport System (ITS), which plays an important role in city traffic management and public travel safety. However, this remains a very challenging task that is affected by many complex factors, such as road network distribution and external factors (e.g., weather, accidents, and holidays). In this paper, we propose a deep-learning-based multi-branch model called TFFNet (Traffic Flow Forecasting Network) to forecast the short-term traffic status (flow) throughout a city. The model uses spatiotemporal traffic flow matrices and external factors as its input and then infers and outputs the future short-term traffic status (flow) of the whole road network. For modelling the spatial correlations of the traffic flows between current and adjacent road segments, we employ a multi-layer fully convolutional framework to perform cross-correlation calculation and extract the hierarchical spatial dependencies from local to global scales. Also, we extract the temporal closeness and periodicity of traffic flow from historical observations by constructing a high-dimensional tensor comprised of traffic flow matrices from three fragments of the time axis: recent time, near history, and distant history. External factors are also considered and trained with a fully connected neural network and then fused with the output of the main component of TFFNet. The multi-branch model is automatically trained to fit complex patterns hidden in the traffic flow matrices until reaching pre-defined convergent criteria via the back-propagation method. By constructing a rational model input and network architecture, TFFNet can capture spatial and temporal dependencies simultaneously from traffic flow matrices during model training and outperforms other typical traffic flow forecasting methods in the experimental dataset.
Demonstration of Optical Coherence Tomography Guided Big Bubble Technique for Deep Anterior Lamellar Keratoplasty (DALK)
Authors: Guo Shoujing , Sarfaraz Nicolas R. , Gensheimer William G. , Krieger Axel , Kang Jin U.
Published: January 2020

Deep anterior lamellar keratoplasty (DALK) is a highly challenging procedure for cornea transplant that involves removing the corneal layers above Descemet’s membrane (DM). This is achieved by a “big bubble” technique where a needle is inserted into the stroma of the cornea down to DM and the injection of either air or liquid. DALK has important advantages over penetrating keratoplasty (PK) including lower rejection rate, less endothelial cell loss, and increased graft survival. In this paper, we successfully designed and evaluated the optical coherence tomography (OCT) distal sensor integrated needle for a precise big bubble technique. We successfully used this sensor for micro-control of a robotic DALK device termed AUTO-DALK for autonomous big bubble needle insertion. The OCT distal sensor was integrated inside a 25-gauge needle, which was used for pneumo-dissection. The AUTO-DALK device is built on a manual trephine platform which includes a vacuum ring to fix the device on the eye and add a needle driver at an angle of 60 degrees from vertical. During the test on five porcine eyes with a target depth of 90%, the measured insertion depth as a percentage of cornea thickness for the AUTO-DALK device was 90.05 % ± 2.33 % without any perforation compared to 79.16 % ± 5.68 % for unassisted free-hand insertion and 86.20 % ± 5.31 % for assisted free-hand insertion. The result showed a higher precision and consistency of the needle placement with AUTO-DALK, which could lead to better visual outcomes and fewer complications.
Fully-Textile, Wearable Chipless Tags for Identification and Tracking Applications

Published: January 2020

In this work, two fully-textile wearable devices, to be used as chipless identification tags in identification and tracking applications are presented. For the fabrication of the fully-textile tags, a layer of fleece was used as a substrate, while an adhesive non-woven conductive fabric was employed for the conductive parts. To allow radio-frequency identification of these chipless tags, two alternative techniques were used. One relies on associating a binary code with the resonance frequency of resonant devices: the presence/absence of the resonance peaks in the transmission scattering parameter, | S 21 | , of a set of resonators is used to encode a string of bits. The second technique for accomplishing radio-frequency identification of the chipless tags resorts to a frequency-shift coding technique, which is implemented by modifying the configuration of a hairpin resonator. The obtained numerical and experimental results confirm the suitability of the proposed strategies for obtaining entirely-textile, wearable chipless tags for identification and tracking purposes, which can be particularly useful, especially in the industrial sector. In this field, in fact, the proposed solutions would guarantee a seamless integration with clothes and would facilitate the user’s interaction with the IoT infrastructure. In this regard, one of the envisaged application scenarios related to the tracking of hides in the leather industry is also presented.
An Assessment of Surface Water Detection Methods for Water Resource Management in the Nigerien Sahel
Authors: Herndon Kelsey , Muench Rebekke , Cherrington Emil , Griffin Robert
Published: January 2020

Water is a scarce, but essential resource in the Sahel. Rainfed ephemeral ponds and lakes that dot the landscape are necessary to the livelihoods of smallholder farmers and pastoralists who rely on these resources to irrigate crops and hydrate cattle. The remote location and dispersed nature of these water bodies limits typical methods of monitoring, such as with gauges; fortunately, remote sensing offers a quick and cost-effective means of regularly measuring surface water extent in these isolated regions. Dozens of operational methods exist to use remote sensing to identify waterbodies, however, their performance when identifying surface water in the semi-arid Sahel has not been well-documented and the limitations of these methods for the region are not well understood. Here, we evaluate two global dynamic surface water datasets, fifteen spectral indices developed to classify surface water extent, and three simple decision tree methods created specifically to identify surface water in semi-arid environments. We find that the existing global surface water datasets effectively minimize false positives, but greatly underestimate the presence and extent of smaller, more turbid water bodies that are essential to local livelihoods, an important limitation in their use for monitoring water availability. Three of fifteen spectral indices exhibited both high accuracy and threshold stability when evaluated over different areas and seasons. The three simple decision tree methods had mixed performance, with only one having an overall accuracy that compared to the best performing spectral indices. We find that while global surface water datasets may be appropriate for analysis at the global scale, other methods calibrated to the local environment may provide improved performance for more localized water monitoring needs.
Exploring the Role of Malaysian Student’s Intrapreneurial Self-Capital in the Relationship between Satisfaction with Life, Academic Performance, and Flourishing
Authors: Bee Seok Chua , Lee Ching Pan , Ismail Rosnah
Published: January 2020

Intrapreneurial self-capital is the construct coined by Di Fabio as a core of individual resources used to cope with career and life construction challenges. In this study, we used the model of Individual Differences in Evaluating Life Satisfaction (IDELS) to examine the mediating role of intrapreneurial self-capital in the relationship between life satisfaction and flourishing among Malaysian undergraduate students. The Intrapreneurial Self-Capital Scale (ISCS), Satisfaction with Life Scale (SWLS), and Flourishing Scale were administered to 665 undergraduate students from one of the public universities in Kota Kinabalu, Sabah, Malaysia. The results reported a significant direct effect of student satisfaction with life to flourishing. A significant path coefficient was also found from satisfaction with life and student academic performance to intrapreneurial self-concept providing the support that student satisfaction with life and academic performance has a positive effect on their intrapreneurial self-concept. The coefficients from intrapreneurial self-concept to flourishing was also significant. This provides initial support that an intrapreneurial self-concept may have a positive mediating effect on the relationship between satisfaction with life, academic performance, and flourishing. We found that the indirect effects of satisfaction with life and academic performance on flourishing through intrapreneurial self-concept were significant. These results provided further support for the mediating effect of intrapreneurial self-concept. The analysis also that revealed satisfaction with life was significantly and positively related to flourishing. However, the finding showed no significant direct effect of student academic performance on flourishing.

Published: January 2020

K-ion batteries (KIBs) have emerged as an auspicious alternative to Li-ion batteries (LIBs) owing to their uniform distribution, plentiful reserves, the low cost of K resources, and their similar physicochemical properties to Li resources. The development of KIBs is seriously limited by cathode materials. Here, a hybrid of K3V2(PO4)3 (KVP) particles triple-coated by amorphous carbon, carbon nanotubes (CNTs), and reduced graphene oxide (rGO) nanosheets (KVP/C/CNT/rGO) was fabricated by a facile ball milling process followed by heat treatment. Consequently, a stable capacity of 57 mAh g−1 can be achieved at 0.2C, and a slow capacity decaying rate (0.06% per cycle) is displayed during 500 cycles under a high current density of 5C. The remarkable reversible capacity and excellent long-term cycling life are mainly due to the enhanced interwoven C/CNT/rGO networks and superior KVP crystal structure stability, which can provide multi-channel for fast electron transport and effective K+ diffusion.

Published: January 2020

Avian botulism is a serious neuroparalytic disease mainly caused by a type C/D botulinum neurotoxin produced by Clostridium botulinum group III, one of the entwined bacterial species from the Clostridium novyi sensu lato genospecies. Its isolation is very challenging due to the absence of selective media and the instability of the phage carrying the gene encoding for the neurotoxin. The present study describes the development of an original method for isolating C. botulinum group III strains. Briefly, this method consists of streaking the InstaGene matrix extraction pellet on Egg Yolk Agar plates and then collecting the colonies with lipase and lecithinase activities. Using this approach, it was possible to isolate 21 C. novyi sensu lato strains from 22 enrichment broths of avian livers, including 14 toxic strains. This method was successfully used to re-isolate type C, D, C/D, and D/C strains from liver samples spiked with five spores per gram. This method is cheap, user-friendly, and reliable. It can be used to quickly isolate toxic strains involved in avian botulism with a 64% success rate and C. novyi sensu lato with a 95% rate. This opens up new perspectives for C. botulinum genomic research, which will shed light on the epidemiology of avian botulism.

Показано, что современное критическое состояние популяции скота ярославской породы в целом во многом было обусловлено и будет зависеть от положения дел в субпопуляциях ведущих по численности разводимого ярославского поголовья областей России. В настоящий период работы с породой в хозяйствах Ивановской и Ярославской областей имеет место значительная генотипическая и фенотипическая контрастность в отношении среднего уровня основных признаков продуктивности и параметров производственного использования коров. Однозначно показано, что массовая по численности скрещиваемых животных и излишняя по степени голштинизация ярославского скота усугубляет ситуацию в соответствующем регионе и отрицательно влияет на породу в целом, приводя к ускоренному фактическому уменьшению поголовья помесных коров главным образом по причинам ухудшения воспроизводительной функции и уменьшения продолжительности их хозяйственного использования.

On the basis of concrete data it is shown that the current critical state of the population of Yaroslavl breed cattle in General was largely due to and will depend on the state of Affairs in the subpopulations of the leading number of bred Yaroslavl livestock regions of Russia. In the present period of work with the breed in the farms of the two leading Ivanovo and Yaroslavl regions there is a significant genotypic and phenotypic contrast with respect to the average level of the main signs of productivity and parameters of production use of cows. It is unambiguously shown that the mass number of crossed animals and excessive degree of Holstein Yaroslavl cattle aggravates the situation in the region and adversely affects the breed as a whole, leading to an accelerated actual reduction in the number of crossbred cows mainly for reasons of deterioration of reproductive function and reducing the duration of their economic use.
СРАВНИТЕЛЬНАЯ ОЦЕНКА ЭФФЕКТИВНОСТИ ПРИЖИВЛЯЕМОСТИ ИНТАКТНЫХ И БИСЕКЦИОННЫХ ЭМБРИОНОВ У ТЕЛОК-РЕЦИПИЕНТОВ

Рассмотрены результаты исследований по оценке эффективности приживляемости интактных и бисекционных эмбрионов крупного рогатого скота у телок-реципиентов. Эмбрионы, полученные от коров-доноров швицкой породы и отобранные в процессе морфологической оценки на стадии развития поздней морулы (n244), были разделены на 2 группы. В I группе эмбрионы (n135) оставили интактными, во II произвели деление интактных эмбрионов (n109) пополам (бисекция) и получили бисекционные эмбрионы (n182), пригодные для пересадки. В обеих группах для обеспечения аналогичности исходных условий эксперимента эмбрионы были культивированы до стадии экспандированной бластоцисты. Затем интактные эмбрионы из I группы и бисекционные эмбрионы из II группы были пересажены телкам-реципиентам. Пересадку эмбрионов осуществляли в верхнюю часть рога матки с использованием катетера для аппликации эмбрионов, по одному каждому реципиенту. Результат приживляемости бисекционных эмбрионов из II группы (53,133,97 ) был ниже на 15,76 в сравнении с уровнем приживляемости интактных эмбрионов из I группы (68,894,01). Несмотря на увеличение исходного количества эмбрионов на 66,97 за счет применения метода бисекции во II группе, количество стельных животных увеличено не было. Таким образом, в процессе исследования определено, что метод бисекции позволяет значительно увеличить число эмбрионов, пригодных к пересадке. Необходимы дальнейшие исследования, направленные на изучение вопроса повышения уровня приживляемости бисекционных эмбрионов у телок-реципиентов.

The paper presents the results on evaluating the engraftment of intact and bisected bovine embryos to recipient heifers. Embryos of Swiss breed donor cows were selected at the late morula stage (n244) and divided into two groups. In the group I (n135) the embryos were remained intact, in the group II (n109) the intact embryos were divided in half (bisection) and 182 bisected embryos suitable for transplantation were obtained. In both groups, to provide the similar initial experimental conditions, the embryos were cultured to the expanded blastocyst stage. Then, the intact embryos from the group I and bisected embryos from the group II were transferred to recipient heifers. Embryo transplantation (one embryo per a recipient) was carried out in the upper part of the uterine horn of recipients using a catheter for application of embryos The engraftment rate of bisected embryos from the group II (53.133.97) was 15.76 lower than the engraftment rate of intact embryos from the group I (68.894.01). As can be seen from this data, despite the increase in the initial number of embryos by 66.97 due to the application of the bisection method in group II, the number of pregnant animals was not increased. Thus, it was determined that the bisection method can significantly increase the number of embryos suitable for transplantation, but further studies are needed to study the issue of increasing the engraftment of bisection embryos to recipient heifers.
Les couples non cohabitants (Living Apart Together) en Europe
Authors: Navas Navarro Susana
Published: January 2020

Les couples LAT posent la problématique du caractère nécessaire ou non d’une cohabitation «habituelle » au sein d’un foyer commun dans la définition du concept de «famille » ou de «forme de vie familiale » . L’exigence de la cohabitation comme condition à la reconnaissance d’une «vie familiale » ou d’une «famille » , ne pose généralement pas de problème dans les affaires traitées par la CEDH ou la CJUE. Il serait nécessaire de réfléchir à l’abrogation du devoir légal de «cohabitation habituelle » dans les relations personnelles entre adultes (ou émancipés), excepté les cas où l’un d’entre eux serait sous la garde de l’autre pour cause d’incapacité. Cela nous emmène à envisager l’abrogation des devoirs légaux conjugaux, dont la portée serait finalement plus éthique que juridique. Le législateur devrait donc réguler seulement le droit d’entretien entre époux.
La nature savante du droit commun

Published: January 2020

Le droit commun est la manifestation de l’expansionnisme de la science du droit, trait qui s’attache à toutes les traditions juridiques reposant sur cette source du droit. En Occident, il est né avec le droit savant médiéval, puis il a conquis les États modernes à la Renaissance. Il a ensuite été réinventé par le droit américain au XIXe siècle avec une science nouvelle sous l’influence de l’École historique allemande. Il est sur le point de conquérir le monde en revenant à sa forme scientifique initiale avec les codifications savantes mondiales et régionales.
Constitution et droit transitoire au Cameroun : Contribution à l’étude de la constitutionnalisation du droit camerounais
Authors: Junior Zambo Zambo Dominique
Published: January 2020

L’influence de la Constitution sur les branches du droit a commencé à être mesurée au Cameroun avec la réforme constitutionnelle du 18 janvier 1996. Cependant, la plupart des études qui l’ont notée, la situe principalement dans le champ des droits fondamentaux. L’ambition de la présente étude est de libérer ce phénomène du carcan droit-de-l’hommiste dans lequel doctrine et jurisprudence l’ont enfermé. Le choix du champ du droit transitoire ne doit rien au hasard. En effet, outre que les règles, en cette matière, sont communes à toutes les disciplines, il est au carrefour de la notion de sécurité juridique. Au bout du compte, si on peut se féliciter de ce que les solutions ici consacrées par la Constitution vont dans le sens de la garantie de la sécurité juridique, et donc de la promotion de l’État de droit, on peut regretter que la protection lacunaire de la prééminence de la Constitution, tempère les bienfaits du progrès accompli, signe, hélas, de son incomplétude.
La méthode en droit comparé. L’approche contextuelle
Authors: Kischel Uwe
Published: January 2020

L’approche contextuelle s’appuie sur le noyau dur du droit comparé traditionnel, c’est-à-dire le fonctionnalisme, tout en soulignant ses problèmes et ses défauts. Ses détracteurs arguent d’un prétendu manque de théorisation et considèrent les méthodes des sciences sociales comme la panacée, essayant ainsi de délégitimer le droit comparé conventionnel. Cette critique idéologique déclare que seuls sont scientifiques les modèles analytiques, empruntés aux sciences naturelles, et essaye d’importer des sciences sociales un débat méthodologique quelque peu épuisé. La proposition de l’approche contextuelle face à ces problèmes est l’herméneutique : il faut se familiariser progressivement avec le droit étranger et le domaine juridique en question, rechercher son style, son atmosphère et développer une intuition fondée sur l’expérience. L’approche contextuelle insiste ainsi sur les aspects pratiques du droit comparé. Analyser et classer les différents contextes juridiques du monde n’est que la conséquence directe de cette méthode : elle essaye de fournir au comparatiste l’information dont il a (tellement) besoin pour comprendre l’atmosphère et le style spécifiques de divers ordres juridiques.
Réflexion sur le socle des ordres juridiques
Authors: Latournerie Marie-Aimée
Published: January 2020

Beyond the difference made between private and public law, significant in France and more widely in all countries marked by the tradition of roman law, intellectual curiosity leads to one point : is there a common base of all legal systems and if so with what features ? Geography and history let hard to think that past and present societies legal systems base is to find in some same principles. However one can maintain that all legal systems, even if they have to be explained by different limiting factors, mental habits and social values, are grounded on a very few commonly perceptible notions, namely person, good, contract, law and order. Therefore the purpose of this article is to underline each of these four notions potential with, at the end, awareness of law temporality.
Étude franco-canadienne du principe légaliste : le processus qualitatif et interprétatif du texte pénal
Authors: Santerre Christine
Published: January 2020

A true pillar in the field of criminal law, the Rule of Law principle a. k. a nullum crimen nulla poena sine lege implies that a person is not to be criminally sentenced pursuant to a specific text within the Law. Does such principle apply in Canada as it does in France ? Does it rise from the same foundations and does it carry the same weight ? Such are the questions the author tries to address in the current study. To that effect, main convergences and divergences in both Canadian and French Criminal Law are bought forward to further oppose two common occurrences of these identities so one will reflect, in a comparative and critical manner, upon them in terms of their significance -both theoretical and pragmatic. Moreover, the first part of this study focusses on the Rule of Law principle as it overtakes the legislator, i. e. in the manner with which the Law demands quality while, in the second part, the emphasis lies on how the judge applies the principle in the context of the interpretation of the repressive text.

Première étape de la réforme économique de la Chine, la réforme du droit d’usage du terrain d’État crée un marché foncier tout en maintenant le système de la propriété publique. La loi sur les droits réels de 2007 confirme la nature de droit réel du droit d’usage du terrain d’État. C’est là un progrès important dans la mesure où le droit chinois évolue vers davantage de protection de la propriété privée. Or, la réforme n’est pas terminée. L’objectif de notre article est d’analyser l’écart entre le droit d’usage du terrain d’État et la propriété et d’expliquer la nécessité de poursuivre ce mouvement dans l’avenir.

Local international conflicts in the age of globalization and contemporary Russia
Authors: Gawrilienkov Aleksey
Published: January 2020

The article discusses the relationship between the occurrence of international conflicts and the desire of states to implement their own geopolitical interests. The key factor in the emergence of conflicts is the concept of an inter-civilization clash by Samuel Huntington, where the role of states in the formation of the international system is the trigger for decision-making. The author states that in modern conditions Russia defends its interests, which should not be perceived by other actors of international relations as a threat, but as competition.

The Russian intervention in Syria has been the first act of a considerable scale since 1991 of a direct involvement of the Armed Forces of the Russian Federation in a military conflict on a territory not included in the former Soviet Union. At the same time, it became the first operation in the history of the Russian Federation (and formerly the USSR) in which a leading role – both in the composition of the military contingent addressed there, as well as in relation to the results of actions – played the air force. This publication focuses on the genesis and the
different phases of the engagement of combat aircraft of the mentioned type of armed forces in the initial stage of Russian intervention, as well as an attempt to assess the reasons for the exceptional effectiveness of the operation on the course of the entire war.

LIVRO DIDÁTICO DE LÍNGUA PORTUGUESA: UM GÊNERO DE DISCURSO MULTIMODAL
Authors: Silva Sandro Luis , Rocha Juliana Souza Lopes Hott da
Published: January 2020

Há muito vem se discutindo a importância do livro didático no processo de ensino-aprendizagem. Neste artigo, trazemos algumas reflexões sobre a interface entre livro didático, gênero de discurso e multimodalidade. Procuramos observar em que medida o livro didático é caracterizado como um gênero de discurso multimodal, uma vez que apresenta uma simbiose de linguagens. Para atingir nosso objetivo, recorremos aos pressupostos enunciativo-discursivos de abordagem sócio-histórica Bakhtin (2011), aliados a fundamentos da multimodalidade, apresentados por Rojo e Barbosa (2015), Dionísio (2013), Bonini (2011) e Maingueneau (2016). Apresentamos como corpus dois livros didáticos do ensino fundamental, o que nos revelou a presença de elementos que fazem com que o livro didático seja considerado um gênero de discurso multimodal, o qual abre perspectiva para o aluno se tornar um leitor crítico, se o livro didático for trabalhado no processo de ensino-aprendizagem como um gênero multimodal.
CLUBE DE LEITURA: ESTRATÉGIA PARA FORMAÇÃO DE LEITORES
Authors: Valente Thiago Alves , Domingos Juliete Rosa
Published: January 2020

Este trabalho apresenta o processo de implementação de um clube de leitura (clube do livro) como um espaço democrático de formação de leitores, tendo em vista o legítimo encontro entre o leitor e a leitura de literatura, em uma escola no interior paulista. O projeto foi construído com base no trabalho de Maria da Glória Bordini e Vera Teixeira de Aguiar, Literatura: a formação do leitor: alternativas metodológicas (1988), que traz reflexões sobre a leitura literária na escola em práticas da sala de aula; e nos estudos de João Luís Ceccantini (2009) que apresentam a “animação de leitura” como proposição para o trabalho de incentivo à leitura. O projeto, portanto, veio ao encontro dos princípios discutidos acerca da escolarização adequada da literatura, principalmente a denominada infantojuvenil, visto que, aliando pressupostos teóricos às práticas pedagógicas, buscou sistematizar ações que centralizaram a leitura do texto literário na escola, respeitando sua natureza específica (LAJOLO, 1982, p. 53).
