Published: September 2024

An important aspect in the operation of converters aggregates with top blowing technology is the influence high-temperature reactionary area of interaction on the thermal bricks in the converter aggregate. Provided the formation of irrational depth of penetration of the reactionary zone of interaction, there is a significant intensification of the wear of the thermal bricks on the bottom of the converter. One way to avoid such a phenomenon is a premature prognosis of the peculiarities of the formation of the reactionary zone of interaction and the depth of its penetration into the layers of the volume of metal melt. Today, there are much information about reactionary zone of interaction and equations for calculate it depth of penetration for different methods top and combine blowing technology in the converter. However, to date we need modern representation of the main types of geometric formation of the reactionary zone of interaction in the oxygen converter with top blowing from tuyere. Regardless of the design the multi-nozzles tip and the blowing modes. According to the purpose and tasks of the work, was offered three main types of the geometric formation of the reaction zone of interaction, in the oxygen converter with top blowing technology, regardless of the design of the multi-nozzles tip and the blowing mode: the separate formation of independent reactionary zones of interaction of certain geometric dimensions, the quantity of which is equal to the quantity of oxygen jets that directly act on the surface of the melt and penetrate its layers; the grouped formation of several united independent reactionary zone of interaction formed by the combination of two or more single reactionary zones created by independent oxygen jets; the united formation of one continuous reactionary zone of interaction due to the fusion of the external contours of all single reactionary areas of interaction, formed by independent oxygen jets. Into the single united reactionary zone of the interaction. In addition, was formed collection of equations to determine Lrzv – the depth of penetration of the reactionary zone of interaction of gas (oxygenes) jets into the melt of metal located in the working space of the converter bath. The separation of equations into collections was made according to the type of physical modeling what was used to obtain them. The first selection of equations obtained on the basis of processing the results of experiments with low temperature physical modeling consists of 13 equations. The second selection includes of equations obtained by processing the results with high temperature physical modeling experiments and consists of 7 equations

The purpose of this work was to investigate the life expectancy, duration of breeding use, and reproductive qualities of sows of the large white breed of French selection, based on the obtained data to develop a new way of evaluating sows according to their operational value, as well as to calculate the economic efficiency of their use in the conditions of the industrial complex. The research was carried out in the conditions of the breeding plant for breeding large white pigs of Agroprime Holding LLC of the Odesa region and the animal husbandry laboratory of the Institute of Grain Crops of the National Academy of Sciences of the Russian Academy of Sciences. Evaluation of sows by indicators characterizing the level of their adaptation and reproductive qualities was carried out taking into account the following characteristics: life expectancy, months; duration of tribal use, months; received farts during the period of breeding use of all, received live piglets of all, head.; multifertility, goal; high fertility, kg; nest weight at the time of weaning at 28 days, kg; preservation of piglets until weaning, %. A comprehensive assessment of the sows of the general sample and different operational values was carried out according to the methodology of Berezovsky (2019) and biometric processing of research results – according to Kovalenko et al. (2010). It was established that the sows of the controlled population are characterized by high indicators of life expectancy, duration of breeding use, and reproductive qualities. Regarding fertility and litter weight at the time of weaning at 28 days, the sows of the controlled population belong to the elite class. A significant difference between sows of the category “high operational value” (I experimental group) and “low operational value” (II sub-experimental group) was established by the duration of life (7.9 months; td = 7.67), the duration of breeding use (8.3 months; td = 7.61), the number of farrowings obtained (1.7 farrowings; td = 9.44), the number of live piglets (24.9 goals; td = 10.50), multifertility (1.1 goals; td = 3.23), high fertility (0.03 kg; td = 0.67), the weight of the nest at the time of weaning at the age of 28 days (8.0 kilograms; td=3.07), survival of piglets before weaning (2.7 %; td = 1.52) and M. D. Berezovsky's index (3.43 points; td = 3.26). The number of reliable correlations between life expectancy, duration of breeding use, absolute indicators of reproductive qualities of sows, and the index “exploitation value of the sow” (EVS) is 75.0 %. The criterion for selecting sows of high operational value for the controlled population is the “EVS” index value at 220.90 or more points.
A Platform for Empowerment: Addressing the Emerging Needs of E-Bike Couriers in Toronto
Authors: Beedell Leslie 
Published: September 2024

<p>Food delivery couriers are at the intersection of two rapidly shifting sectors: the platform economy and electric mobility. These workers are often recent immigrants using cars or e-bikes, regardless of the winter weather or the presence of supportive public space. Toronto has made an environmental goal to increase delivery by bicycle but lacks a coherent strategy of transitioning workers from cars to bikes (City of Toronto, 2021b). The aim of this study is to determine the priorities of bike couriers and the role of municipalities in providing for this group of workers. This study determines the priorities and needs of couriers through participant observation and a survey. Stakeholder interviews and a policy scan were used to understand the role of the municipality in addressing these challenges. The study finds that couriers prioritize 1) e-bike charging facilities, 2) cycling paths, and 3) public washrooms. Couriers also report wanting more socialization, which under an equity lens should be considered given the marginalized status of many couriers. Finally, the study uses GIS to propose locations for 'e-bike hubs' which could meet the needs highlighted by the survey. The study has implications for active transportation, inclusive cycling advocacy, and public realm planning. </p>

Published: September 2024

<p>This research investigates the incorporation of limestone calcined clay cement (LC3), super-sulfated cement (SSC), and calcium aluminate cement (CAC), as different chemical make-up cements with lower CO<sub>2</sub> emissions than OPC, in sustainable engineered cementitious composites (ECC) mixtures. Slump flow, compressive and flexural strengths, deflection capacity, ultrasonic pulse velocity (UPV), rapid chloride permeability, and shrinkage behaviors of LC3-, SSC-, and CAC-based ECCs were assessed at different curing ages, while considering the addition of fly ash (FA) at various FA/cement ratios of 0, 0.8, 1.2, and 1.5. In addition, the self-healing ability of these green cements-based ECCs was tested by exploring their recovery after pre-cracking and further water curing. SEM-EDS analyses were also performed to characterize the recovery products related to each cement. The results confirmed the possibility of using LC3, SSC, and CAC in sustainable ECCs, with greater mechanical, durability, and self-healing performances compared to the control OPC-ECC. </p>

O objetivo deste artigo é relatar um caso de Púrpura Trombocitopênica Trombótica (PTT) com manifestações neurológicas significativas, destacando a importância do diagnóstico precoce e do manejo terapêutico adequado para melhorar o prognóstico dos pacientes. Paciente adulto, previamente hígido, que apresentou sintomas de PTT em outubro de 2022, 49 anos, foi admitido com cefaleia intensa, desorientação e equimoses, associado a plaquetopenia, anemia hemolítica microangiopática e comprometimento renal e cardíaco. O diagnóstico de PTT foi baseado em trombocitopenia grave, anemia hemolítica, presença de esquizócitos, elevações de LDH e bilirrubina, e níveis reduzidos de ADAMTS13. A terapia incluiu corticoides, caplacizumabe e plasmaférese, com resposta clínica parcial. No entanto, o paciente desenvolveu novas manifestações neurológicas, incluindo dislalia e isquemia cerebral, evidenciadas por tomografia computadorizada. A análise do caso sugere que a deficiência severa de ADAMTS13 foi o principal fator relacionado à gravidade das complicações neurológicas, mesmo havendo dissociação entre local da isquemia e clínica apresentada. Este estudo de caso contribui para a literatura ao detalhar um episódio raro e grave de PTT com complicações neurológicas, ressaltando a necessidade de intervenções rápidas e precisas para evitar a progressão da doença. Apesar das limitações inerentes ao estudo de caso único, os achados reforçam a importância do tratamento imediato, incluindo plasmaférese e imunossupressão, para reduzir a mortalidade e melhorar a recuperação dos pacientes com PTT.
Integrative study of chicken lung transcriptome to understand the host immune response during Newcastle disease virus challenge

Published: September 2024

IntroductionNewcastle disease is one of the significant issues in the poultry industry, having catastrophic effects worldwide. The lung is one of the essential organs which harbours Bronchus-associated lymphoid tissue and plays a vital role in the immune response. Leghorn and Fayoumi breeds are known to have differences in resistance to Newcastle disease. Along with genes and long non-coding RNAs (lncRNAs) are also known to regulate various biological pathways through gene regulation.MethodsThis study analysed the lung transcriptome data and identified the role of genes and long non-coding RNAs in differential immune resistance. The computational pipeline, FHSpipe, as used in our previous studies on analysis of harderian gland and trachea transcriptome was used to identify genes and lncRNAs. This was followed by differential expression analysis, functional annotation of genes and lncRNAs, identification of transcription factors, microRNAs and finally validation using qRT-PCR.Results and discussionA total of 8219 novel lncRNAs were identified. Of them, 1263 lncRNAs and 281 genes were differentially expressed. About 66 genes were annotated with either an immune-related GO term or pathway, and 12 were annotated with both. In challenge and breed-based analysis, most of these genes were upregulated in Fayoumi compared to Leghorn, and in timepoint-based analysis, Leghorn challenge chicken showed downregulation between time points. A similar trend was observed in the expression of lncRNAs. Co-expression analysis has revealed several lncRNAs co-expressing with immune genes with a positive correlation. Several genes annotated with non-immune pathways, including metabolism, signal transduction, transport of small molecules, extracellular matrix organization, developmental biology and cellular processes, were also impacted. With this, we can understand that Fayoumi chicken showed upregulated immune genes and positive cis-lncRNAs during both the non-challenged and NDV-challenge conditions, even without viral transcripts in the tissue. This finding shows that these immune-annotated genes and coexpressing cis-lncRNAs play a significant role in Fayoumi being comparatively resistant to NDV compared to Leghorn. Our study affirms and expands upon the outcomes of previous studies and highlights the crucial role of lncRNAs during the immune response to NDV.ConclusionThis analysis clearly shows the differences in the gene expression patterns and lncRNA co-expression with the genes between Leghorn and Fayoumi, indicating that the lncRNAs and co-expressing genes might potentially have a role in differentiating these breeds. We hypothesise that these genes and lncRNAs play a vital role in the higher resistance of Fayoumi to NDV than Leghorn. This study can pave the way for future studies to unravel the biological mechanism behind the regulation of immune-related genes.

Published: September 2024

IntroductionThis study examines storytelling’s role in supporting organizational resilience for equitable STEM instruction by schools and districts. Within K-12 organizations, some practices may be perceived as mundane, but storytelling supports transformation toward achieving equitable STEM learning opportunities in a school. Therefore, storytelling is a means for achieving organizational resilience.MethodsThrough a comparative case study design, this paper explores challenges identified by educational leaders through focus groups who worked with teams to activate interdisciplinary learning to support thriving STEM programming to enhance equitable science instruction.ResultsWe characterize STEM systems’ social and organizational phenomena from three educational contexts. We start by sharing these systems’ backgrounds and educational goals, with specific attentiveness to their STEM programming. We then share the stories told by their leaders to promote organizational resilience (these characteristics, as previously described, are italicized throughout this section) within each of the given contexts.DiscussionThe STEM stories in this study shared the state of STEM within a school and district, the instructional mission of STEM, and a community STEM story.

Published: September 2024

IntroductionBacterial infection and biofilm formation contribute to impaired healing in chronic diabetic wounds. Staphylococcus aureus and Pseudomonas aeruginosa are found in human diabetic wound biofilms. They may develop antibiotic resistance, increasing the urgency for alternative or complementary therapies. Diabetic wound healing may be improved with the use of biomedically engineered scaffolds, which can also serve as delivery systems for antibacterial compounds. Manuka honey is a potent antibacterial and wound care agent due to its high osmolarity, low pH, and constituents (such as methylglyoxal). Honey exhibits bacteriostatic and bactericidal effects, modulates the expression of biofilm forming genes, and restores antibiotic susceptibility in previously drug resistant pathogens.MethodsIn this study, we created a dermal regeneration template (DRT) composed of polycaprolactone-gelatin (PCL-gelatin) and Manuka honey to retain honey in the wound and also provide a scaffold for tissue regeneration.Results and discussionSoluble Manuka honey inhibited the planktonic and biofilm growth of both S. aureus (UWH3) and P. aeruginosa (PA14) co-cultures. Manuka honey embedded PCL-gelatin scaffolds did not exhibit bacteriostatic or bactericidal effects on cocultures of UHW3 and PA14; however, they promoted the expression of AgrA, a gene associated with dispersal of S. aureus biofilms.
