TRANSFORMACIONES EN LA ESTRUCTURA AGRARIA DE MISIONES (ARGENTINA): ANÁLISIS EN PERSPECTIVA HISTÓRICA-AMBIENTAL
Authors: Zang Laura Mabel , Haugg Diana Elizabeth
Published: March 2023

El presente artículo analiza los cambios y permanencias en la estructura productiva de Misiones (Argentina), a partir de un abordaje interdisciplinario. En esta línea, el análisis del estado del arte favoreció el reconocimiento de etapas constitutivas de la estructura agraria de Misiones vinculadas primero a la actividad extractivista de la yerba mate (segunda mitad del siglo XIX); luego con el proceso colonizador hacia fines de este siglo y primeras décadas del XX. La economía extractiva dio lugar a una economía productiva a partir del desarrollo de actividades agrarias con fuerte centralidad del cultivo de yerba mate. Finalmente, a partir de la década de 1970 es posible identificar la consolidación del sector forestal dentro de los espacios rurales de Misiones. La metodología empleada es cualitativa y descriptiva con análisis de fuentes primarias, secundarias y realización de entrevistas a actores claves en el fenómeno estudiado. Los resultados pusieron en evidencia que, en las últimas décadas, la actividad forestal tuvo un profundo impacto en la estructura agraria de Misiones.

Indirect immunofluorescence - tissue staining in TMA and whole tissue FFPE sections v1
Authors: Martinez Casals Anna
Published: March 2023

Immunofluorescence staining allows detection and localization of antigens in different tissue types providing high sensitivity. The indirect immunofluorescence protocol is based on the principle of using a primary antibody binding to the target epitope, and a fluorophore-tagged secondary antibody that recognizes and binds to the primary antibody. This methods provides signal amplification allowing detection of several targets in the same tissue sample. This detailed protocol describes an adapted protocol, from An atlas of the protein-coding genes in the human, pig, and mouse brain article, for tissue staining in Tissue MicroArrays (TMA) and whole tissue Formalin Fixed Paraffin Embedded (FFPE) sections which is used in Emma Lundberg research group at Science for Life Laboratory; KTH - Royal Institute of Technology.

Authors: Cavenaghi-Altemio Angela Dulce , Graciano Fonseca Gustavo , Macedo Adriane , Piccoli Andressa
Published: March 2023

Background: There are few studies on the evaluation of meat from hybrid sorubins. Objective: Thus, the aim of this work was to evaluate the physical, chemical, microbiological and sensorial characteristics of fillets of Amazon and real hybrid sorubins. Method: Proximate composition, instrumental colour, water holding capacity, cooking losses and shear force were measured. Microbiological analyses of the fillets were carried out for Salmonella sp. and Staphylococcus aureus to ensure food safety of the judges during sensory analysis. Results: Hybrid sorubim fillets presented an excellent quality, being classified in category A (lipids below 5% and proteins between 15% and 20%). There was no significant difference (p>0.05) between the evaluated fillets for several parameter: the average water holding capacities were 33.72 and 34.67%, the cooking losses were 14.93 and 13.41%, the shear forces were 2.21 and 1.74 kgf, and the luminosities were 49.61 and 45.04 for the fillets of Amazonian hybrid sorubim and real hybrid sorubim, respectively. Discussion: There was an evident relation between water holding capacities and shear forces. Amazonian hybrid sorubim fillets were more accepted due to their lower intensity of red. However, there was no sensorial difference between the hybrids, and both had an acceptance rate above 80%. Conclusion: It was concluded that the hybridization does not alter the sensory characteristics of the fish fillets.
Cross-Cultural Integration through the Lens of Loneliness: a Study of Chinese Direct Entry Students in the United Kingdom
Authors: O'Dea Xianghan , Stern Julian
Published: March 2023

This study explores cross-cultural integration of Chinese top-up students in a UK university from the perspective of loneliness. Existing research on integration has underplayed loneliness. This study used semi-structured interviews to collect data at three key transition points during the top-up year. The findings suggest that students experienced loneliness both within and beyond their group, notwithstanding a number of reasons why they might be expected to be less lonely than other international students. Loneliness seemed to have a significant impact on cross-cultural integration, and participants were also unable to form strong bonds within their cohort of Chinese top-up students, and unable to experience healthy solitude. There are implications for the pre-departure preparation of such students, for the institutions hosting such students, and for responses to the social and emotional challenges they experience.
“Because more trust now”: The Role of Peer Observation of Teaching in Building a Faculty Community of Practice
Authors: Deraney Philline
Published: March 2023

As the main facilitators of teaching and learning, faculty developers’ views as individuals and as members of their academic communities are essential to higher education research. Yet, developers’ perceptions of their own growth and learning as practitioners are underrepresented in the extant literature. This qualitative study explored perceptions of a peer observation of teaching (PoT) program and its role in building a community of practice (CoP) amongst a nine-member team of faculty developers in a large university in Saudi Arabia. Participant data were collected through semi-structured interviews after two years of the program.  A thematic content analysis of  interview responses revealed four themes: 1) authentic collegiality and mutual communication improved through the shared experiences, which provided a foundation for the CoP; 2) participants’ perceptions of PoT shifted from an evaluative experience to a developmental one with noticeable challenges; 3) teaching and learning strategies and practices were enhanced from the observation experiences;  and, 4) PoT contributed to building community through shared practice and/or sense of belonging. Implications of this study support explicit discussions about the foundation and underlying values of proposed PoT and related programs; a balanced, outcome-oriented yet still developmental program with follow-up opportunities; and, learner-centered and sustainable development that empowers a bilateral role and identity as both academician and faculty developer.
Synchronous multiphase electric drive with main control power channel
Authors:   Ivanovo State Power Engineering University, Golubev A.N.
Published: March 2023

One of the options to improve the technical and economic characteristics of a synchronous electric drive is to design it based on an actuating motor with an increased number of phases. However, the characteristics of m-phase (m > 3) synchronous motor associated with the transfer of electromagnetic energy by a whole spectrum of spatial harmonic fields sets the task to develop an automatic control system that considers these features. The method to calculate the characteristics of an m-phase synchronous motor in quasi-stationary modes based on the use of spectral vectors of electromagnetic parameters for its individual substructures as a control object is used. The authors have proposed an approach to study and calculate energy characteristics of m-phase synchronous motor for different control laws implemented on the basis of equations of its design equivalent circuit. The results of the study of the main energy characteristics of the engine for various control laws along the main energy channel are presented. To implement the advantages of a multiphase synchronous motor, it is necessary to force the required mutual arrangement of the flux linkage vectors and stator current for higher spatial harmonics. It can be implemented based on the multi-channel principle of control system design.

Published: March 2023

Thermal methods that have several environmental and economic advantages are widely applied for water treatment at thermal (TTP) and nuclear power plants (NPP) along with chemical methods. Multistage flash evaporation plants are important in case of use of thermal methods for desalinated water treatment as they can use low-temperature steam of thermal power plants. Despite the considerable number of scientific papers on this issue, the effective performance and improvement of the heat and mass transfer process in evaporator plants remains an urgent task, especially with variable operating modes of the technological equipment of TPPs and NPPs. On the one hand, it is due to the need to match the variable parameters of steam and the variable flow rates of make-up water for the process needs of the station. On the other hand, it is due to the lack of universal methods to calculate and design the equipment. Thus, the development of new methods to model and improve heat and mass transfer processes in thermal water treatment plants of thermal power plants and nuclear power plants is an urgent task for the power energy industry and related ones. To solve the problems of modeling heat and mass transfer processes in flash evaporation plants, models based on the mass and energy balance equations have been used. The obtained differential and linear equations are solved by analytical methods and methods of mathematical programming. A matrix model of the process of heat and mass transfer in a multi-stage multi-flow evaporative flash installation has been developed, considering evaporation of part of the water when it enters the low-pressure region. The steady-state pressure distribution over the stages and the performance of each stage of the evaporative installation have been found. Comparison of the calculated and known results have shown an adequate description by means of the model of the real process of heat and mass transfer in flash evaporation plants. It makes possible to set and solve problems to choose the optimal design and operating parameters of equipment for multi-flow evaporation plants. The proposed method to solve the problem of modeling heat and mass transfer provides the possibility of simultaneously search for acceptable values of design and operating parameters of multistage evaporative plants for various purposes.
Maximum Product Spacings Estimator for Fuzzy Data Using Inverse Lindley Distribution
Authors: Chaturvedi Ankita , Singh Dr. Sanjay Kumar , Singh Dr. Umesh
Published: March 2023

The article addresses the problem of parameter estimation of the inverse Lindley distribution when the observations are fuzzy. The estimation of the unknown model parameter was performed using both classical and Bayesian methods. In the classical approach, the estimation of the population parameter is performed using the maximum likelihood (ML) method and the maximum product of distances (MPS) method. In the Bayesian setup, the estimation is obtained using the squared error loss function (SELF) with the Markov Chain Monte Carlo (MCMC) technique. Asymptotic confidence intervals and highest posterior density (HPD) credible intervals for the unknown parameter are also obtained. The performances of the estimators are compared based on their MSEs. Finally, a real data set is analyzed for numerical illustration of the above estimation methods.
THE ROLE OF SOCIAL MEDIA IN THE RUSSIAN-UKRAINIAN INFORMATION WAR
Authors:   Taras Shevchenko national University of Kyiv, Batrymenko Oleh
Published: March 2023

The article presents the results of a systematic study of the role of social media in covering the events of the Russian-Ukrainian war, which are one of the relevant tools in conducting an information conflict between Ukraine and the aggressor country. It is argued that social media help overcome traditional barriers to mass communication. Thus, not only the amount of available information is added, but also the number of active participants in information and communication processes. Today, the latter include not only official bodies of public authority, but all concerned citizens. The differences between the strategies used by the Russian Federation and Ukraine regarding the social networks and platforms are emphasized. For example, the aggressor state severely limits the access of its citizens to independent sources, prohibiting the latter from actively operating on its territory, while using social media for propaganda and disinformation both far away on the territory of its country and beyond. In Ukraine, social media is primarily used for instant delivery of relevant information to citizens, spreading the true narrative among its own population and outside the state. At the same time, it is emphasized that the use of social media in the information war has both advantages and disadvantages. On one hand, speed and availability are clear pluses, but the problem of credibility and multiplicity of narratives can be counted among the minuses. A number of tips have been developed for consumers of social network content that can help avoid confusion.

Authors: ŞAHİN Münir
Published: March 2023

The quality of teachers, who have important contributions in the life of every individual who makes up the society, will directly affect the quality of the society we live in. For this reason, the Ministry of National Education made a new regulation regarding the professional rights of teachers and enacted the Teaching Profession Law. The aim of this study is to determine the evaluations of teachers and administrators regarding the newly enacted Teaching Profession Law which is expected to be in force after 15 February 2023. As qualitative research, the study was designed according to the phenomenology pattern. The study was carried out with a total of 89 participants, including 14 school administrators and 75 teachers working in different provinces. According to the findings obtained from the study, most of the participants did not support the transformation of teaching into a career profession and made negative comments. However, almost all of the participants (94%) made positive evaluations regarding the new additional indicator regulation. It has been observed that with the new regulation teachers have expectations that they will primarily gain financial rights, increase their motivation, and develop in terms of knowledge and skills. However, more than half of the participants (58.2%) stated that the regulations made would not lead to qualitative changes. Almost all of the teachers (97.4%) positively evaluated that the distinction between contracted and permanent teachers must be abolished.

Published: March 2023

In pattern recognition fields, it is worthwhile to develop a pattern recognition system that hears one and knows ten. Recently, classification of printed characters that are the same fonts is almost possible, but classification of handwritten characters is still difficult. On the other hand, there are a large number of writing systems in the world, and there is a need for efficient character classification even with a small sample. Deep learning is one of the most effective approaches for image recognition. Despite this, deep learning causes overtrains easily, particularly when the number of training samples is small. For this reason, deep learning requires a large number of training samples. However, in a practical pattern recognition problem, the number of training samples is usually limited. One method for overcoming this situation is the use of transfer learning, which is pretrained by many samples. In this study, we evaluate the generalization performance of transfer learning for handwritten character classification using a small training sample size. We explore transfer learning using a fine-tuning to fit a small training sample. The experimental results show that transfer learning was more effective for handwritten character classification than convolution neural networks. Transfer learning is expected to be one method that can be used to design a pattern recognition system that works effectively even with a small sample.

In Thailand, the pineapple is a valuable crop whose price is determined by its sweetness. An optical refractometer or another technique that requires expert judgment can be used to determine a fruit's sweetness. Furthermore, determining the sweetness of each fruit takes time and effort. This study employed the Alexnet deep learning model to categorize pineapple sweetness levels based on physical attributes shown in images. The dataset was classified into four classes, i.e., M1 to M4, and sorted in ascending order by sweetness level. The dataset was divided into two parts: training and testing datasets. Training accounted for 80% of the dataset while testing accounted for 20%. This study's experiments were repeated five times, each with a distinct epoch and working with data that had been prepared. According to the experiment, the Alexnet model produced the greatest results when trained with balancing data across 10 epochs and 120 figures per class. The model's accuracy and F1 score were 91.78% and 92.31%, respectively.

Nowadays, advances in information and communication technologies along with easy access to electronic devices such as smartphones have achieved an agile and efficient storing, edition, and distribution of digital multimedia files. However, lack of regulation has led to several problems associated with intellectual property authentication and copyright protection. Furthermore, the problem becomes complex in a scenario of illegal printed exploitation, which involves printing and scanning processes. To solve these problems, several digital watermarking in combination with cryptographic algorithms has been proposed. In this paper, a strategy of robust watermarking is defined consisting of the administration and detection of unauthorized use of digitized cinematographic images from Mexican cultural heritage. The proposed strategy is based on the combination of two types of digital watermarking, one of visible-camouflaged type based on spatial domain and another of invisible type based on frequency domain, together with a particle swarm optimization. The experimental results show the high performance of the proposed algorithm faced to printing-scanning processes or digital-analogue attack, and common image geometric and image processing attacks such as JPEG compression. Additionally, the imperceptibility of the watermark is evaluated by PSNR and compared with other previously proposed algorithms.

Published: March 2023

With advancement in technology, especially in imaging field, digital image forgery has increased a lot nowadays. In order to counter this problem, many forgery detection techniques have been developed from time to time. For rapid and accurate detection of forged image, a novel hybrid technique is used in this research work that implements Gray Level Co-occurrence Matrix (GLCM) along with Binary Robust Invariant Scalable Keypoints (BRISK). GLCM significantly extracts key attributes from an image efficiently which will help to increase the detection accuracy. BRISK is known to be one of the 3 fastest modes of detection which will increase the execution speed of GLCM. BRISK even processes scaled and rotated images. Then the Principal Component Analysis (PCA) algorithm is applied in the final phase of detection will remove any unrequited element from the scene and highlights the concerned forged area.
ImECGnet: Cardiovascular Disease Classification from Image-Based ECG Data Using a Multibranch Convolutional Neural Network
Authors: Ghahremani Amir , Lofi Christoph
Published: March 2023

Reliable Cardiovascular Disease (CVD) classification performed by a smart system can assist medical doctors in recognizing heart illnesses in patients more efficiently and effectively. Electrocardiogram (ECG) signals are an important diagnostic tool as they are already available early in the patients’ health diagnosis process and contain valuable indicators for various CVDs. Most ECG processing methods represent ECG data as a time series, often as a matrix with each row containing the measurements of a sensor lead; and/or the transforms of such time series like wavelet power spectrums. While methods processing such time-series data have been shown to work well in benchmarks, they are still highly dependent on factors like input noise and sequence length, and cannot always correlate lead data from different sensors well. In this paper, we propose to represent ECG signals incorporating all lead data plotted as a single image, an approach not yet explored by literature. We will show that such an image representation combined with our newly proposed convolutional neural network specifically designed for CVD classification can overcome the aforementioned shortcomings. The proposed (Convolutional Neural Network) CNN is designed to extract features representing both the proportional relationships of different leads to each other and the characteristics of each lead separately. Empirical validation on the publicly available PTB, MIT-BIH, and St.-Petersburg benchmark databases shows that the proposed method outperforms time seriesbased state-of-the-art approaches, yielding classification accuracy of 97.91%, 99.62%, and 98.70%, respectively.

Published: March 2023

The intensive use of land has accelerated the loss of soil quality, a process that can be avoided by adopting conservationist production systems, such as the Integrated Crop-Livestock-Forest (CLFI system). It is noteworthy that in the Southwest of the State of Maranhão a substantial portion of soils in rural properties are degraded and in distinct stages of erosion, since they have been exploited for decades with non-properly managed pastures. Therefore, the objective of this work was to emphasize the importance of physical and chemical changes in the soil of pastures under crop-livestock-forest integration in  general and in the Amazon region of state of Maranhão, Brazil. Therefore, a literature review was conducted through a search for studies in the Google Scholar database, which encompasses multiple other databases, such as Scielo, Elsevier, Scopus, Capes, and others. In face of the conditions of degradation in pastures throughout the state of Maranhão and the broad distribution of native forests such as Babassu forests, the use of technology from CLFI systems could allow for their recovery and sustainable status by means of economically and ecologically feasible productivity. Research on this field is therefore necessary to highlight short- and long-term efficiencies regarding carbon sequestration and quality of organic matter on the soil.

Published: March 2023

The study aimed to determine the interference periods of weeds in cassava ‘IAC 90’ cultivated in different cycles and cropping systems. An experiment was conducted in the period 2014/15 (1st cycle) and another was conducted from the pruning of cassava plants in the period 2015/16 (2nd cycle). The experimental design was a randomized block design with split-split plots and four replicates. The plots represented the cropping systems (conventional and no-tillage) and the split-split plots corresponded to the periods with and without coexistence with weeds (0, 25, 50, 75, 100, 125, 150, 175, 200 and 225 days after planting or pruning - DAP/DAPr). In the 1st cycle, there was no interaction between the cropping systems and the coexistence periods and, therefore, based on the acceptable losses of 5% in the root and starch yield of 'IAC 90' cassava, the PCPI was estimated between 20 and 212 DAP and 14 to 214 DAP, respectively. In the 2nd cycle, the CPPWI ranged from 17 to 176 DAPr and 30 to 216 DAPr based on the root and starch yield obtained in the conventional method, respectively. While in no-tillage, the estimated CPPWI ranged from 18 to 198 DAPr and 9 to 218 DAPr based on root and starch yield, respectively. In general, the data indicate that conventional weed management should be carried out in a more intensified way than in no-tillage. In addition, CPPWI based on starch losses can avoid losses in root production.
Brazilian Agricultural Frontier: Land Grabbing, Land Policy, and Conflicts
Authors: Sehn Korting Matheus , Assumpção e Lima Débora , Sobreiro Filho José
Published: March 2023

This article sheds light on the forms of land appropriation in the agricultural frontier regions of Brazil in line with the concepts of land and green grabbing. With less stringent environmental laws, the Cerrado presents itself as a ‘sacrifice zone’, where grabbers and large agricultural producers have sought to register lands of the Amazon biome as ‘Cerrado’ or an undefined biome zone land. It seeks to understand what happens in territories when power technologies, that is, disciplinary mechanisms such as the Rural Environmental Cadastre (CAR), are activated and how the state has regulated land appropriation and green grabbing as a new meaning of appropriation of nature. This has created obstacles for the struggle and resistance of socio-territorial movements for land distribution, as confirmed by the growing lethality of conflicts in Brazilian frontier zones that are coveted by the grabbers.

Published: March 2023

The article presents a methodology for optimizing transport costs with the use of modeling in PTV Visum software package. Based on the analysis of transport problems in large urban agglomerations, a quality criterion was chosen for the assessment of passenger transport performance. An approach has been proposed to introduce transport hub systems with the purpose to minimize time spending on transfer, in particular, and on trip by public transport in a whole. This optimization method for transport spending represents an algorithm of 3 key blocks: the formation of transport model for being studied agglomeration, the placement conditions and the choice of transport hub locations. The model is formed on the base of 4-step approach, the trips distribution in a network is based on entropy approach which is considered in the second section in more details. The placement conditions go from an idea to minimize time total spending on moving, the number of hubs being introduced is limited by their construction financing.
The approach application is demonstrated on the example of northwestern urban agglomeration Sertolovo-Osinovaya Roshcha-Pargolovo which represents being actively built-up residential districts on St. Petersburg city border. The specificities of its transport network, including also hubs and highways with complicated traffic, are determined. Based on open sources and statistical data, a transport model was developed, its calibration was pursued. 3 options for placing transport hubs on network of the agglomeration are presented. As a result of the research, the analysis for the options of transport hub placements is presented and the most promising option from the view of purpose meaning achievement for hub placement in being considered agglomeration is proposed.
Mode of action of Akkermansia muciniphila in the intestinal dialogue: role of extracellular proteins, metabolites and cell envelope components
Authors: Segers Anneleen , de Vos Willem M.
Published: March 2023

Akkermansia muciniphila is a promising next-generation beneficial microbe due to its natural presence in the mucus layer of the gut, its symbiotic ability to degrade mucus, and its capacity to improve the intestinal barrier function. A. muciniphila is able to counteract weight gain and immuno-metabolic disturbances in several animal models. Many of these disorders, including obesity and auto-immune diseases, have been associated with decreased gut barrier function and consequent increased inflammation. Since A. muciniphila was found to normalize these changes and strengthen the gut barrier function, it is hypothesized that other beneficial effects of A. muciniphila might be caused by this restoration. In search for A. muciniphila’s mode of action in enhancing the gut barrier function and promoting health, we reasoned that secreted or cell envelope components of A. muciniphila are interesting candidates as they can potentially reach and interact with the epithelial barrier. In this review, we focus on the potential mechanisms through which A. muciniphila can exert its beneficial effects on the host by the production of extracellular and secreted proteins, metabolites and cell envelope components. These products have been studied in isolation for their structure, signaling capacity, and in some cases, also for their effects in preclinical models. This includes the protein known as Amuc_1100, which we here rename as pilus-associated signaling (PAS) protein , the P9 protein encoded by Amuc_1631, the short-chain fatty acids acetate and propionate, and cell envelope components, such as phosphatidylethanolamine and peptidoglycan.

It was concluded that the results of the presentation-based macromedia flash design as a learning medium for static electricity material were accurate and could be utilized by junior high school students.
Comment sa politique environnementale a-t-elle conduit l'Union européenne à intervenir dans les politiques forestières ?
Authors: Flies Robert
Published: March 2023

Cet article présente l’évolution depuis les années 1960 du cadre législatif communautaire et de la politique forestière mis en place par l’Union européenne (UE) pour protéger les forêts tout en conservant les prérogatives sur les ressources forestières au niveau des États membres. D’abord raisonnée dans le cadre de la politique agricole, la protection des forêts a été intégrée au début des années 2000 à la politique environnementale. Ainsi, la politique de l’environnement de l’UE est devenue la pierre angulaire de la stratégie forestière 2030. Cette stratégie illustre comment le secteur forestier a intégré des thématiques plus horizontales dans la gestion forestière comme la bioéconomie, le changement climatique ou la préservation de la biodiversité.
Messages clés :• La politique de l’environnement de l’Union européenne a eu des incidences considérables sur les politiques forestières des États membres.• Il n’est pas nécessaire, pour protéger les forêts de l’Union, d’instaurer une politique forestière commune.• Les défis actuels du secteur forestier s’articulent autour du climat, de la biodiversité et de la bioéconomie.• Le secteur forestier doit faire valoir son savoir et son expertise dans l’arène européenne tout en renforçant les collaborations avec les autres secteurs.
Écoulements de résine et nécroses chez le Cèdre de l'Atlas : analyse des symptômes dans un dispositif sylvicole expérimental

Un suivi des écoulements de résine sur troncs de cèdre associés à des nécroses cambiales a été réalisé entre 1992 et 2017 dans un dispositif sylvicole. Le taux d'arbres atteints a progressivement augmenté jusqu'à 50 % en 2015 avec une différence marquée entre traitements sylvicoles en 2004 (densité et hauteur d'élagage et interaction). En 2017, une analyse sur 84 arbres a montré que les nécroses se développent de préférence à la base du houppier vivant, à un âge cambial de 21-22 ans. Les nécroses et canaux résinifères apparaissent les années plutôt humides, notamment 2008. Les nécroses cicatrisent pour la plupart en 2-3 ans. L'intervention d'un champignon est suspectée.
Messages clés :• Des écoulements de résine associés à des nécroses cambiales sont signalés sur Cèdre.• Dans un dispositif expérimental sylvicole, les arbres à houppier développé (éclaircie forte, sans élagage) sont transitoirement plus touchés.• Les symptômes apparaissent préférentiellement à la base du houppier vivant (âge cambial de 21-22 ans) et plutôt les années humides.• On suspecte l'intervention d'un champignon.
Effet de la sylviculture sur les potentialités de production du Pin d'Alep (Pinus halepensis Mill.) dans l'Aurès algérien. Établissement de tables de production pour deux itinéraires sylvicoles

Published: March 2023

L’étude menée sur 230 placettes temporaires de Pin d’Alep (Pinus halepensis Mill.) dans l’Aurès (Algérie) a pour objectif de construire deux tables de production pour deux itinéraires sylvicoles différents. Quatre classes de fertilité ont été définies avec des hauteurs dominantes à 70 ans de 19,50 m, 16,50 m, 13,50 m et 10,50 m, respectivement. Les effets de l’itinéraire sylvicole ne changent pas la production totale de bois en volume mais modifient la répartition des catégories de diamètre avec une proportion de gros bois de plus en plus élevée, ce qui permet une meilleure valorisation économique des peuplements.
Messages clés :• Deux tables de production ont été construites pour le Pin d’Alep en Algérie.• Ces tables intègrent deux itinéraires sylvicoles.• Selon l’itinéraire choisi, la valorisation économique est différente.
Incendies de forêts : obtenir réparation des préjudices subis
Authors: Liagre Jacques
Published: March 2023

Les incendies très importants de forêts de l’été 2022 questionnent sur les responsabilités pénales ou civiles des auteurs de ces faits dans le cadre d’incendies criminels ou accidentels mais également sur les possibilités d’indemnisation des propriétaires dont le bien a été détruit. Cet article aborde d’une façon exhaustive le cadre législatif complexe de la réparation des préjudices subis par les propriétaires de forêts. Les définitions de l’action publique et de l’action civile sont rappelées. Selon les différentes origines des incendies, les différents régimes de réparation sont présentés, ainsi que les cas de jurisprudence
Messages clés :• La réparation des préjudices subis après un incendie peut faire appel à des actions publique (droit pénal et punition) ou civile (responsabilité sans punition).• Les réparations dépendent des origines des incendies (naturelles, accidentelles par l’homme ou volontaires).• Les procédures et les recherches de preuve sont souvent très complexes.• Les possibilités d’indemnisation des propriétaires en cas d’incendies criminels sont quasiment nulles.
Immediate Effects of Quadriceps Muscle Kinesiology Taping on Joint Position Sense and Force Sense in Healthy Individuals
Authors: Maqsood Mariam , Váczi Márk
Published: March 2023

(1) Background: Within the scope of prevention studies, many researchers have indicated the need to enhance knee proprioception. Kinesiology tape is one product that claims to enhance proprioception, however, its use has not been well researched in the healthy population before. The aim of the study was to investigate if kinesiology tape application on the quadriceps muscle enhances proprioception. (2) Methods: Twelve healthy and physically active volunteers (M=7, F=5, mean age= 20.75 ± 2.14, mean BMI=22.25 ±2.34) participated in the study. With computerized, custom-built isokinetic dynamometer, we recorded perceived joint position angles (small and large angles). For force sense, we recorded maximum voluntary isometric contractions (MVIC) and differences in torques (Nm) via force matching tasks both with vision and without vision on left leg. The absolute errors for joint position sense measurements and for force matching tasks and differences in MVIC both in untaped and taped conditions for left legs of all subjects were recorded. (3) Results: Two-way repeated measures ANOVA revealed that no significant interaction existed among small and large angle groups in both the conditions nor any main condition effect was observed in both the groups. (p>0.05). Similarly, no differences were accounted in force matching tasks between the taped and un-taped with vision and without vision (p=0.52 and 0.38 respectively.) Statistically insignificant increments were observed in mean torque post application. (p=0.67) (4) Conclusions: Present study suggests that immediate kinesiology tape application on quadriceps muscle offers no benefits on proprioception in terms of joint position sense and force sense hence other preventive measures to strengthen the proprioceptive system should be relied upon.
