The use of bio-based composite as building materials is one of the innovative solutions for dealing with environmental disorders caused by the construction sector. Among these materials we find biocomposites based on vegetable aggregates, which have proven their effectiveness as insulating materials in numerous studies. Despite the growing interest in these materials and the recognition of their performance, their use remains hampered by the lack of implementation rules specific to these materials to move towards a control of their use and their durability affected by the climate and use conditions to which they will be exposed at the level of a building. The objective of this work is to study the compatibility of a protective coating with a block substrate of biocomposites based on cereal straw. It is in fact a mixture of vegetable aggregates (straw), a binder composed of lime and additives also obtained from a renewable source (Ismail et al., 2020). These additives (air-entraining agent, casein protein and a biopolymer) have been added to improve both the fibre-binder interface and the porosity of the binder. The use of these bio-based materials for external or internal thermal insulation of the building requires the application of a coating to protect them against climatic aggressions and to give them an aesthetic appearance. The lime-based coatings, air-entraining agent and casein protein selected for this study have been the subject of an experimental investigation (Brahim Ismail, 2020). In order to assess the compatibility of these coatings with the straw-based insulating material, we were interested in studying the adhesion between the biocomposite and the coating after aging cycles in accordance with the EN 1015-21 standard. The samples (biocomposite + coating) were subjected to two types of aging, one using water and the other using a saline solution of sodium sulphates (Na2SO4). The results of the bond tests after aging showed that the cohesive fracture (at the level of the substrate) is a pattern observed in all the studied systems. In Addition, It has been found that the coating to which a percentage of fine fibers has been added undergoes considerable degradation after aging with salt solution, demonstrating the need of an additional layer of outer coating without fibers in order to ensure the sustainability of the system.

This article reviews Irena Grudzińska-Gross’s book Miłosz i długi cień wojny [Milosz and the Long Shadow of War], which was published by Pogranicze in 2020. The reviewer analyses the definition of violence and its relation to Polish narratives of wartime solidarity seen as heroism. To this end, she examines the work of Czesław Miłosz, written during the Second World War, and later texts thematising the war experience. An additional layer of the publication is the poet’s take on the Jewish question – both in the context of Miłosz’s poetic works and the subsequent discussions they provoked. The author, taking into account Miłosz’s autobiogeographical predispositions, also analyses the changing images of Warsaw in his works as a space where the poet spent most of the war. For this reason, she examines the poet’s attitude to the Warsaw Uprising and the public perception of his decision not to join the cause.

Compositionality is undoubtedly one of the hardest problems in linguistics. In decoding theories, the speaker occupies a leading role, having to carefully choose the form that better encodes the meaning to be communicated. In contrast, in inferential theories, the burden is shifted from speaker to hearer: linguistic information typically underspecifies meaning and the hearer must make a number of inferences to bridge the gap between what is said and what is meant. In this article, I argue that constructional meaning can aid the process of sentence meaning formation by providing a scaffold that can help the hearer with the construal operations. Constructions, by providing an additional layer of meaning, constrain the range of possible meanings activated by words thereby reducing the combinatorial explosion when several words are joined together. This process is examined here by analysing the meanings associated with the grammatical construction [from X to Y], which is connected to a polysemy network of related senses, using examples extracted from a multimodal corpus. A preliminary analysis of the gesturing behaviour associated with the different senses proposed is also included, which can be seen to contribute to the characterisation of the different senses of the polysemy network.

This report is informed by the themes of the session Trisomy 13/18, Exploring the Changing Landscape of Interventions at NeoHeart 2020—The Fifth International Conference of the Neonatal Heart Society. The faculty reviewed the present evidence in the management of patients and the support of families in the setting of trisomy 13 and trisomy 18 with congenital heart disease. Until recently medical professionals were taught that T13 and 18 were “lethal conditions” that were “incompatible with life” for which measures to prolong life are therefore ethically questionable and likely futile. While the medical literature painted one picture, family support groups shared stories of the long-term survival of children who displayed happiness and brought joy along with challenges to families. Data generated from such care shows that surgery can, in some cases, prolong survival and increase the likelihood of time at home. The authors caution against a change from never performing heart surgery to always—we suggest that the pendulum of intervention find a balanced position where all therapies including comfort care and surgery can be reviewed. Families and clinicians should typically be supported and empowered to define the best care for their children and patients. Key concepts in communication and case vignettes are reviewed including the importance of supportive relationships and the fact that palliative care may serve as an additional layer of support for decision-making and quality of life interventions. While cardiac surgery may be beneficial in some cases, surgery should not be the primary focus of initial family education and support.

On-road vehicles equipped with driving automation features—where a human might not be needed for operation on-board—are entering the mainstream public space. However, questions like “How safe is safe enough?” and “What to do if the system fails?” persist. This is where remote operation comes in, which is an additional layer to the automated driving system where a human remotely assists the so-called “driverless” vehicle in certain situations. Such remote-operation solutions introduce additional challenges and potential risks as the entire vehicle-network-human now needs to work together safely, effectively, and practically. Unsettled Issues in Remote Operation for On-road Driving Automation highlights technical questions (e.g., network latency, bandwidth, cyber security) and human aspects (e.g., workload, attentiveness, situational awareness) of remote operation and introduces evolving solutions. The report also discusses standards development and regulations—both of which are needed to provide frameworks for the deployment of driving automation with remote operation.

As a result of the analytical review, it was established that the family of Yolo models is a promising area of search and recognition of objects. However, existing implementations do not support the ability to run the model on the iOS platform. To achieve these goals, a comprehensive scalable conversion system has been developed to improve the recognition accuracy of arbitrary models based on the Docker system. The method of improvement is to add a layer with the Mish activation function to the original model. The method of conversion is to quickly convert any Yolo model to CoreML format. As part of the study of these techniques, a model of the neural network Yolov4_TCAR was created. Additionally, a method of accelerating the load on the CPU using an additional layer of neural network with the function of activating Mish in Swift for the iOS mobile platform was added. As a result, the effectiveness of the Mish activation function, the CPU load of the mobile device, the amount of RAM used, and the frame rate when using the improved original Yolov4-TCAR model were studied. The results of the research confirmed the functioning of the algorithm for conversion and accuracy increase of the neural network model in real-time.

For Aboriginal and Torres Strait Islander Jarjums (children), the cultural and world views they bring from their home life can be very different to those in school, creating an additional layer of adjustments in the Early Years pathway. We describe an Early Years Transitions Framework that demonstrates how changing transition from a process to move Jarjums as quickly as possible into a Western system to one that acknowledges the beliefs and cultural artefacts Jarjums bring to the Early Years space builds smoother transitions. The Framework is underlain by a mesh of High-Expectations Relationships, which moves the educator from the position of ‘knowledge holder’ to one of deep listening to understand the cultural needs and aspirations of families. By bringing these different world views together and building relationships across the Early Years sectors, educators can create a third cultural space where transition becomes a process of interwoven spaces and incremental learning.

Purpose. To reveal the mechanism of formation of contact zones and purposeful choice of mastic composition and its substantiation on the basis of revealing of regularities of interrelations "mastic composition – waterproofing resource". Methodology. The sequence of changes in the technical condition of roofing materials, which varies from normal without damage to emergency with intermediate satisfactory and unsuitable for normal operation depending on the specific damage and leakage of the roof affects the definition of conventional material resources, means and methods of arrangement and arrangements. roofs, as well as the mechanism and kinetics of loss of serviceability are a key factor in improving the whole set of measures aimed at making technology competitive. Results. Technologies of repair of point and local damages in the form of cracks, breaks, exfoliations which are carried out by cutting and the subsequent gluing of pieces of cloths on the prepared sites with filling, allow to receive short-term results. Elimination of continuous surface damage by applying an additional layer of rolled or mastic material is associated with the inevitable preservation in the lower layers of the causes of premature loss of operational functions of the coating. The results provide an opportunity to perform non-dismantling repair and restoration work using purposefully proposed repair composition with the minimum possible cost of resources and a high degree of mechanization. The developed technology is based on the ability of the used repair composition to impregnate and saturate the adjacent surfaces with ingredients that can eliminate damage of a certain type and return the coating or protective layer of the initial waterproofing potential and strengthen it. Originality. Substantiation of possibilities of use of the residual waterproofing resource of the existing soft roof by its saturation with ingredients of the offered repair composition. Practical value. It is possible to effectively use, restore and enhance the residual waterproofing potential of bitumen-roofing roof by pneumatic spraying repair composition of the developed composition.

Abstract Research with hard-to-reach, monolingual adults from ethnic minority communities can present a multitude of challenges throughout the research process. This presentation will highlight challenges and lessons learned from two pilot studies with Vietnamese-, Cambodian-, and Korean-American family caregivers aged 50 and older. The first study (n=9) implemented a one-on-one, telephone-based psychosocial intervention before the COVID-19 pandemic; the second is an ongoing study (n=12) consisting of a group-based intervention via Zoom. Throughout recruitment, the following challenges arose: addressing the lack of familiarity with research among caregivers, earning the trust of caregivers, and identifying creative ways to recruit caregivers to participate. During study implementation, common challenges included: caregivers’ unpredictable daily schedule that made it difficult to participate in the scheduled classes, caregivers feeling apprehensive about technology and Zoom, access to reliable internet, and facilitating participation and engaging the voices of caregivers over the phone or via Zoom. Strategies were identified to address these barriers: engaging the support and collaboration of trusted, bilingual and bicultural community-based providers, building culturally-responsive rapport with caregivers, and seeking continuous feedback from caregivers to improve the appeal of the project implementation. The COVID-19 pandemic added an additional layer of difficulty to the research, requiring creativity and flexibility in implementation that took into consideration caregivers’ heightened anxiety, distress, lack of participation due to around-the-clock care, and loss and grief. The challenges and lessons learned from these studies could guide the development of future research efforts and strategies to effectively engage older hard-to-reach, monolingual Asian American caregivers.

A method for allohernioplasty of indirect inguinal hernia has been developed, in which an additional layer consisting of the peritoneum of the hernial sac is formed between the spermatic cord and the mesh. The peritoneal flap prevents direct contact between the mesh and the spermatic cord and ensures rapid absorption of inflammatory serous fluid. The manifestations of implant-associate inflammation of the spermatic cord and persistent seromas decrease in the tissues. The method was applied in 25 patients in the period from 2017 to 2021.
