It is well known that mechanical damage to trees, caused by felling and removal of timber from the forest, has multiple negative effects on the quality of the stock and the health of the forests as well as the volume increment. In Bosnia and Herzegovina there were no significant analises of volume increment loss due to bark damage of the trees. In this paper, a direct relationship between the significant damage to the bark of the stem and the size of the volume increment of individual trees was determined. Original data recorded during the Second National Forest Inventory in Bosnia and Herzegovina (2006-2009), within the accesible high economical forests was used. These forests cover a total area of 1.329.500 ha.
Data on measured trees was taken from every fourth sample plot (one from cluster). 18.546 trees were selected, on which the 10-year increment of brest diameter (DBH) was measured and significant mechanical damage was recorded (LOJO et al., 2008). Of the total number of selected trees, 2.635 or 14.21% were mechanically damaged.
The results of the study showed that the volume increment of trees, with significant bark damage of all tree species and thickness, was lower from 4,9% to 19,4% in average, compared to undamaged trees.
Based on registered damage the bark of the stem, during second NFI BiH and determined the average losses increment on individual trees, it was estimated how much these losses are on an annual basis in, productive high forests in Bosnia and Herzegovina.
The volume increment of mechanically damaged trees is statistically significantly lower compare to the increment of undamaged trees, resulting in a total loss of about 200.000 m3 / year / 1.329.500 ha.

Published: November 2021

Introduction : Depuis mars 2020, le Québec (Canada), comme le reste du monde, vit une crise sanitaire majeure résultant de la pandémie de COVID-19. En plus des nombreux décès occasionnés par le virus, des personnes vivront leur fin de vie dans ces temps mouvementés où les mesures d’urgence sanitaire forcent leur isolement et modifient en profondeur l’organisation et la pratique des soins de fin de vie. Au Québec, 64 % des personnes qui sont décédées étaient des résidents de Centre d’hébergement et de soins de longue durée (CHSLD), une population considérée hautement vulnérable. Cependant, le risque de mourir de la COVID-19 est inégal entre les régions sociosanitaires du Québec, suggérant, par le fait même, la possibilité que des mesures organisationnelles et cliniques différentes aient été mises en place dans divers milieux.Objectif : L’article présente le protocole d’une étude visant à mieux comprendre les effets de la COVID-19 sur les soins de fin de vie en CHSLD par l’identification de transformations organisationnelles et cliniques ainsi que le contraste de deux régions différemment affectées, soit Montréal et l’Estrie.Méthodes : Un devis descriptif-explicatif est utilisé. Des entrevues sont réalisées avec les coordonnateurs de site et les soignants ayant travaillé en CHSLD durant la première vague de COVID-19 afin d’identifier les transformations vécues et leurs effets sur les soins offerts aux résidents en fin de vie, ainsi que sur le personnel soignant.Discussion et conclusion : Les conclusions de ce projet mèneront à des recommandations sur le plan organisationnel, clinique, politique et scientifique.

Introduction : Les infirmières sont exposées régulièrement à des événements difficiles dans leur travail. Dès le début de l’année 2020, cette exposition, augmentée dans le contexte de la pandémie de COVID-19, fragiliserait leur santé psychologique. À ce jour, le portrait de la santé psychologique de ces professionnelles de la santé et ses déterminants dans le contexte québécois demeurent méconnus, mais nous pouvons anticiper que la pandémie affecte négativement la santé psychologique des infirmières.Objectifs : Cet article décrit le protocole de recherche d’une étude observationnelle transversale chez les infirmières du Québec. Cette étude vise à produire des données probantes sur la santé psychologique de ces infirmières pendant la pandémie.Méthodes : Ce protocole est publié rétrospectivement à la collecte de données qui a été réalisée entre juillet et septembre 2020. Un total de 15 000 infirmières du Québec sélectionnées à l’aide d’un échantillonnage aléatoire simple ont été invitées à répondre à un sondage en ligne. Des statistiques descriptives et des analyses de régressions multivariables seront utilisées pour décrire les participantes et leur santé psychologique et ses déterminants.Discussion et conclusion : Les résultats anticipés de cette étude seront comparés à la littérature sur le sujet. En effet, d’autres auteurs ont mesuré la santé psychologique dans différents contextes (épidémie, pandémie, pays, population). Ces résultats serviront de base pour développer et déployer une intervention à l’échelle provinciale afin d’améliorer la santé psychologique de cette population de travailleurs.
Currículos Outros, Sujeitos Outros: novas paisagens no território curricular a partir de uma narrativa-experiência docente
Authors: Araujo de Oliveira Danilo , Ferrari Anderson 
Published: November 2021

Nosso foco de problematização se inscreve nas relações entre currículo e subjetividades, tomando como provocação a narrativa-experiência de uma professora universitária no encontro com o imprevisível da sala de aula. Perseguindo esse foco de problematizar as relações entre o currículo e as subjetividades, organizamos o texto em três partes: a expectativa, o encontro e a mudança. Todas essas partes dizem e dão forma à narrativa-experiência da professora junto às alunas e aos alunos e seus questionamentos em torno do currículo e de si mesma como resultado desse currículo, mas, sobretudo, nos conduzem para as potencialidades da sala de aula na construção de outros currículos e outros sujeitos. As perspectivas teórico-metodológicas que orientam nossas análises são a pós-critica de currículo e a inspiração dos estudos de Michel Foucault. A narrativa-experiência aqui acionada por nós para pensar o território curricular mostra que, entre os seus ordenamentos, o currículo demanda um tipo específico de professora e professor, aquela e aquele que busca se munir de ferramentas e garantir a realização de um plano e conduzir sua conduta de certo modo, mas, no encontro com o imprevisível do currículo, essa posição de sujeito professora esvanece. Nossa defesa é de que, na sala de aula, emergem possibilidades de constituição de novas paisagens no território curricular que, como efeito, permitem a constituição de currículos outros e sujeitos outros.
Cognição como atividade humana criadora em vivências de estudantes de pedagogia
Authors: Cardoso Gomes Maria de Fátima , Ferraz Almeida Neves Vanessa , Prazeres Silva Luciana 
Published: November 2021

Neste artigo discutimos diferentes trajetórias escolares por meio de Estudos de Casos de três estudantes de uma turma de Psicologia da Educação, do Curso de Pedagogia da Universidade Federal de Minas Gerais e seus familiares. As estudantes e seus familiares relataram vivências (perejivânia) tensas e dolorosas nessas trajetórias. Tais vivências nos impulsionaram a perguntar: Como pensar a cognição como uma atividade humana criadora? Como relacionar a cognição com as práticas sociais em que ela é gestada? No contexto das salas de aulas daquela universidade, os letramentos acadêmicos foram ressaltados nos discursos das estudantes e pudemos conhecer a força do afeto constituindo e sendo constituído pela cognição social situada, pela força das culturas e das linguagens em uso. Argumentamos que esses conceitos estão intimamente relacionados nas vivências relatadas, em alguns momentos um ou outro se torna mais saliente, porém estão sempre em diálogo, constituindo as pessoas. O diálogo entre teoria e empiria levou-nos à compreensão da indissociabilidade entre afeto, cognição, culturas e linguagens e, consequentemente, à proposição de uma síntese: a unidade de análise [afeto/cognição social situada/culturas/linguagens em uso] — ACCL — com base na Psicologia Histórico-cultural, que defende a unidade afeto/cognição, e na Etnografia em Educação, que argumenta que culturas e linguagens em uso são inseparáveis. A unidade ACCL permitiu-nos olhar para as pessoas, humanizando suas trajetórias escolares, bem como possibilitou-nos não as estigmatizar ou rotulá-las como deficientes.
Efficiency of Polymer Light‐Emitting Diodes: A Perspective
Authors: Van der Zee Bas , Li Yungui , Wetzelaer Gert‐Jan A. H. , Blom Paul W. M. 
Published: November 2021

AbstractThe various contributions to the external quantum efficiency (EQE) of polymer light‐emitting diodes (PLEDs) are discussed. The EQE of an organic light‐emitting diode is governed by a number of parameters, such as the electrical efficiency, the photoluminescence quantum yield (PLQY), the optical outcoupling efficiency and the spin statistics for singlet exciton generation. In the last decade, the electrical efficiency has been determined from a numerical PLED device model. More recently, an optical model to simulate the fraction of photons outcoupled to air for PLEDs with a broad recombination zone has been developed. Together with the directly measured PLQY, the EQE of a PLED can then be estimated. However, it has been observed that the measured EQEs of fluorescent PLEDs, including the model system super‐yellow poly(p‐phenylene vinylene) (SY‐PPV) often exceed the expected values. To solve this discrepancy, it is demonstrate that the electrical PLED model has to be expanded by the inclusion of triplet–triplet annihilation (TTA), which is shown to be responsible for a substantial EQE enhancement. Experimentally, it is obtained that TTA contributes to a singlet‐exciton generation efficiency of ≈40% in SY‐PPV PLEDs, giving rise to an EQE of ≈4% instead of the expected value of 2.5%.

AbstractMethylammonium lead iodide perovskite (MAPbI3) is today considered the most promising component for highly efficient third generation solar cells. However, the lifetime of the solar devices is strongly affected by the stability of the MAPbI3 films toward humidity, UV irradiation, and temperature. The search for efficient protective additives to be used for building up composite perovskite films with enhanced stability is a topic of great interest in the scientific community. In the present paper, a layered zirconium phosphate‐phosphonate based on N,N‐phosphonomethylglycine, exfoliated in thin nanosheets (NS), as additive for the stabilization of MAPbI3 crystalline films toward humidity, UV‐irradiation, and temperature changes is applied. Notably, the additive is extremely efficient in preventing degradation of the perovskite film, preserving the optical and structural properties, and avoiding the phase transitions normally observed due to temperature increase.

Published: November 2021

AbstractInvisible photonic patterns based on responsive photonic crystals show great potential in structural‐color encryption. However, single inherent information (structural color) encryption/decryption means and the incomplete invisibility in normal conditions greatly limit further development in high‐precision encryption. Here, a novel invisible photonic pattern encrypted/decrypted by dual optical information (structural color and brightness) is reported. It is prepared by engineering an extremely large wettability difference into the patterned and unpatterned regions of a vapor‐responsive inverse opal film. The same optical properties and the distinct wettability difference between the two regions not only ensure that the pattern encrypted by structural color and brightness in the normal state can be entirely hidden under the microscope, but also ensure that it can be decoded by large color contrast (Δλ = 26–32 nm) and brightness contrast (ΔB = 48–57.6) under flowing water vapor state. The unique invisible photonic pattern, reported for the first time, can inject new life into structural color‐based encryption.

Published: November 2021

AbstractThe second near‐infrared (NIR‐II) window is highly effective in fluorescent bioimaging to obtain a deep view of living systems. Among numerous NIR‐II fluorescent agents, organic fluorophores have been considered as ideal candidates in this field. Thus, modulation strategies should be considered to improve the performance and functionality of such agents. This review provides an overview of the development and construction of organic NIR‐II fluorophores. More importantly, the modulation strategies focused on improving the performance and functionality of organic NIR‐II fluorophores are summarized and discussed in detail. Furthermore, the conclusion and future directions of the modulation strategy are presented as well.

AbstractThe morphology and elemental compositions at the surface of poly(styrene sulfonic acid) (PSSA) grafted poly(ethylene‐co‐tetrafluoroethylene) polymer electrolyte membranes (ETFE‐PEMs) in a grafting degree (GD) range of 0%–127% are investigated by using FE‐SEM and XPS analyses. The concentrations of elemental components at the surface are not a linear function of GDs, resulting from different grafting speeds at the surface and bulk. In addition, low accumulation of PSSA grafts on the surface of ETFE‐PEMs in the low GDs of 0%–19%, as well as their homogeneous distribution through the membranes at least at a GD of 19% are observed. At higher GDs of 19%–127%, the PSSA accumulation on the surface is relatively limited, indicating the presence of more PSSA grafts inside the bulk than on the surface. The surface signatures of ETFE‐PEMs over the entire GD range can be determined based on the grafting process. These interesting observations suggest the significant advantages of interfacial properties of ETFE‐PEMs for fuel cell applications.

AbstractPoly(vinyl alcohol) (PVA)/chitosan (CS) blends represent one of the most studied bicomponent systems constituted between a natural biomacromolecule and an easily biodegradable synthetic polymer. Yet, in order to control and improve the physical, hydrolytic, and mechanical stability of these systems, by adding safe linkers to bind the free hydrophilic groups, there is much work to be done. In the present work, histamine (H) reinforced PVA/CS tri‐components blended films have been developed via casting from solution technique. Before casting, rheology measurements were conducted on the studied solutions, then, all the PVA/CS/H matrices were subjected to FTIR studies, scanning electron microscopy, contact angle, water absorption capacity, surface roughness measurements, antimicrobial, and in‐vitro biocompatibility studies. Results of the morphological studies showed that pores were uniformly dispersed on the matrix while the surface roughness increased in the films when a higher ratio of histamine was used. The studies revealed significant enhancement in the water absorption capacity of the histamine reinforced blends compared with the pristine PVA/CS film. Cellular behavior studies performed on epithelial (MCF line 7) cells revealed comparable proliferative and adhesion activity of tri‐component PVA/CS/H films compared to that of pristine PVA/CS films.
Spatio‐temporal feature fusion based correlative binary relevance for visual object detection
Authors: M Amaresh , S Chitrakala 
Published: November 2021

AbstractObject detection in video is an emerging and challenging research topic in Computer Vision. Recently, deep learning based approaches achieves greater results in object detection. The major issues in detecting multiple objects from the videos are exploiting low‐level visual concepts and temporal information and also exploring the correlation between the objects in the videos. Therefore, to address the above mentioned issues, the spatio‐temporal feature fusion based correlative binary relevance (STFF‐CBR) classifier is proposed to generate a rich vector representation and exploit the label correlation for the object detection in videos. In this article, first, the spatio‐temporal feature fusion (STFF) is proposed to exploit the low‐level visual concepts and temporal information in the videos which significantly improves the object detection performance. Second, correlative binary relevance (CBR) classification approach is proposed to exploit the dependencies between the labels in the video using the nearest neighbor based label dependency graph (LDG). Additionally, feed forward neural network (FFNN) classifier is utilized to increase the classification accuracy of the CBR method. Experimental evaluation shows that the STFF‐CBR classifier model achieves better performance for object detection problem in video against the state‐of‐the‐art methods.

AbstractChild welfare practices in the last century have been linked to a high risk for child maltreatment and the subsequent development of mental ill‐health. However, not all affected individuals develop clinically relevant psychopathology, which can be considered as a form of resilience. Such resilience is insufficiently understood in survivors of an advanced age. Therefore, this exploratory study aimed to depict a resilience profile of Swiss older adult survivors of child welfare‐related maltreatment (n = 132; Mage = 71 years) and to contrast it with age‐matched controls (n = 125). Approximately 30% of survivors did not meet the diagnostic criteria for any of the assessed current or lifetime DSM‐5 disorders. These survivors were older, experienced less physical abuse, and had higher trait resilience, self‐esteem, income, and satisfaction with their socio‐economic status. They had lower levels of neuroticism and some empathy characteristics. Group differences in the resilience profiles suggest that resilience‐related aspects may vary as a function of past adversity.

Published: November 2021

SummaryInternet of underwater things (IoUT) has garnered significant attention for monitoring and exploration applications in underwater scenarios. The interconnected devices used in IoUT have power constraint as batteries are difficult to recharge or replace. Multihop cooperative communication can help reduce the power requirement of a single node by breaking the long distance links into two or more high quality segments. In this paper, we investigate the end‐to‐end average bit error rate (BER) of the multihop underwater relay network. The nodes are connected to each other using optical wireless communication link which provides high data rates with low latency. Closed form expressions for average BER are derived for two scenarios: (1) where every hop channel has the same statistical behavior and (2) each channel is characterized by different statistical behavior. Further, the impact of channel parameters on the system performance is analyzed and discussed.

Published: November 2021

AbstractGlobal level assumptions of numerical models have received relatively less attention, but have been indicated to be a major source of error in numerical modeling of Reinforced Concrete (RC) structures. In parallel, it has been stated that a statistical approach involving many virgin specimens and ground motions is necessary for model validation. Such an approach would require very small‐scale testing. Then, the reinforcement fabrication becomes a major issue. This paper proposes using additive manufacturing to fabricate the reinforcement cage. It presents the results from cyclic tests on 1:40 RC cantilever members. The cages were manufactured using an SLM 3D printer able to print rebars with submillimeter diameters. Different longitudinal and transverse reinforcement configurations were tested. A numerical model using existing Opensees elements was built and its parameters were calibrated against material level small‐scale tests. It captured the cyclic response of the RC members with a reasonable accuracy. The cyclic behavior of the RC members resembles the behavior of full‐scale RC members indicating that such small‐scale specimens can be used for the statistical validation of the global level assumptions of numerical models.
