Published: June 2024

A demanda crescente por filhotes de raças específicas tem impulsionado as vendas nos canis comerciais de reprodução, entretanto, grandes perdas econômicas estão diretamente relacionadas à mortalidade desses animais. As causas dessas mortes em neonatos são multifatoriais, podendo ser de etiologias infecciosas e/ou não infecciosas. No presente relato, descreve um caso de herpesvírus canino que afetou neonatos de um canil da raça Shih Tzu na cidade de Sorocaba - SP, em 2020, o qual participou de dois projetos de pesquisa com foco em otimizar a reprodução e o desempenho comercial. O primeiro utilizou-se a cabergolina para estudar a possibilidade de diminuição do intervalo interestro, foi elaborado para a investigação dos efeitos imunológicos devido ao uso da cabergolina. Durante a primeira pesquisa, mortes súbitas de neonatos aparentemente saudáveis começaram a ocorrer e o projeto veio a ser interrompido para investigação dos óbitos. No processo de investigação, realizou-se o exame de diagnóstico viral em espécimes clínicos de origem animal, o qual foi positivo para Herpesvírus

Published: June 2024

We consider a degenerate/singular wave equation in one dimension, with
drift and in presence of a leading operator which is not in divergence
form. We impose a homogeneous Dirichlet boundary condition where the
degeneracy occurs and a boundary damping at the other endpoint. We
provide some conditions for the uniform exponential decay of solutions
for the associated Cauchy problem.
“Breaking Ground: Lenmeldy’s Approval and the Future of MLD Treatment”

Published: June 2024

Metachromatic leukodystrophy (MLD), a lesser-known disease, is a
critical focus in the study of lysosomal storage disorders. It is
inherited in an autosomal recessive manner. ARSA and PSAP genes are
primarily responsible for this, as they mutate, leading to a shortage of
available arylsulfatase A lysosomal enzyme and sphingolipid activator
protein (SapB), respectively. Without this enzyme and protein,
sulfatides accumulate as metachromatic granules in cells of the nervous
system, such as oligodendrocytes and Schwann cells, and hinder myelin
production, paving the way for demyelination. Demyelination gives rise
to a plethora of symptoms, including but not limited to: motor function
impairment, ataxia, optic atrophy, spasms, and impaired cognition
(1,2,3). MLD is diagnosed best by the detection of mutations by
sequencing. However, it can also be diagnosed by checking how much
sulfatides are present in the patient’s urine and plasma, brain MRI,
biochemical tests for ARSA enzymatic activity, and even by evaluating
peripheral nerve size using ultrasound as well as clinical
manifestations (1,4). While MLD is a rare disease, it is still one of
the foremost leukodystrophies worldwide, found in 1 in every
40,000–160,000 (1). However, owing to its rarity and the many unknowns
surrounding this disease, there have been no authorized treatments for
MLD, with supportive care being the only management option. Despite
these challenges, a breakthrough has emerged in the form of Lenmeldy
gene therapy, recently approved by the FDA on March 18, 2024 (5). This
gene therapy, the first of its kind to be approved by the FDA, offers
hope to individuals with MLD and their families for a better quality of
life and potentially improved outcomes. In this commentary, we will
delve deeper into the FDA’s approval of Lenmeldy gene therapy and its
implications for the future treatment of MLD.

Authors: Srivastava Gunjan , Padhiary Subrat Kumar , Mohanty Neeta , Patil Pravinkumar G. , Panda Saurav , Cobo-Vazquez Carlos , Çakmak Gülce , Molinero-Mourelle Pedro
Published: June 2024

Objectives: To evaluate the current evidence of digital workflow feasibility based on the data acquisition methods and the software tools used to fabricate intraoral prostheses for patients with partial or total maxillary and mandibular defects.
Materials and methods: An electronic search was performed in PubMed, SCOPUS, and Web of Science using a combination of relevant keywords: digital workflow, digital designing, computer-assisted design-computer aided manufacturing, 3D printing, maxillectomy, and mandibulectomy. The Joanna Briggs Institute Critical Appraisal Tool was used to assess the quality of evidence in the studies reviewed.
Results: From a total of 542 references, 33 articles were selected, including 25 on maxillary prostheses and 8 on mandibular prostheses. The use of digital workflows was limited to one or two steps of the fabrication of the prostheses, and only four studies described a complete digital workflow. The most preferred method for data acquisition was intraoral scanning with or without a cone beam computed tomography combination.
Conclusion: Currently, the fabrication process of maxillofacial prostheses requires combining digital and conventional methods. Simplifying the data acquisition methods and providing user-friendly and affordable software may encourage clinicians to use the digital workflow more frequently for patients requiring maxillofacial prostheses.

Published: June 2024

The revitalisation of post-harbour and waterfront areas is an issue that has been subject to intensive public discussion over the recent years. The topic is becoming increasingly popular due to the high value of post-harbour areas. They are distinguished by their aesthetic, environmental and recreational qualities. The possibilities for developing such areas are considerable: residential development, waterfront park areas, public spaces, a variety of service developments. So far, many successful projects of such transformation have been carried out. This article focuses on an analysis of the conditions and potential of the Port of Zeran in Warsaw and the possibilities for its transformation. The study was carried out by desk research using available spatial data and information provided in scientific publications. A survey was also carried out on a group of 146 Zeran residents. The results of the analyses showed that the local environment is under heavy anthropopressure and the social and technical infrastructure is in very poor condition, while the area also has many advantages and significant development potential. The most important of these include the convenient location, the favourable ownership situation, the multitude of areas not yet developed and the presence of elements related to former activities. The current condition of the harbour offers opportunities for development in both recreational and leisure and residential directions. It is also possible to create a mixed-use neighbourhood, and the potential development would have a positive impact on the entire neighbourhood.
Conventional triaxial loading and unloading test and PFC numerical simulation of rock with single fracture
Authors: Tang Yin , Chen Haijun , Xiong Liangxiao , Xu Zhongyuan
Published: June 2024

Take the metamorphic sandstone as the reference object, by making rock like samples with fractures, the conventional triaxial loading and unloading test and PFC numerical simulation of rock like sample with single fracture were conducted, and the effects of the loading path, inclined angle of fracture, axial stress level during unloading, initial confining pressure during unloading on the compressive strength, peak strain and crack propagation evolution of the samples were considered. The compressive strength of the specimen under triaxial unloading is smaller than that under triaxial loading. The peak strain of the specimen under triaxial unloading is also smaller than that under triaxial loading. The specimen is more prone to brittle failure. When the axial stress level is the same during unloading, with the increase of the initial confining pressure during unloading, the difference of the compressive strength of the specimens with different inclined angles of fracture gradually decreases. Under the condition of uniaxial compression and triaxial compression, the failure of all specimens is tensile failure, and the shear failure is the main one during unloading.
Design of flexural strengthening based on fib Bulletin 90
Authors: Kotynia Renata , Kaszubska Monika
Published: June 2024

This paper presents the analysis of intermediate and end debonding failure in slab strengthened using carbon tapes (Carbon Fiber Reinforced Polymer). The calculations are based on the more accurate method in the latest fib Bulletin 90. Consideration of additional effects based on three conditions: basic bond, bond friction and member curvature in the intermediate crack debonding analysis give the ratios ΔFf Ed/ΔFf Rd from 0.01 to 0.11, depending on the cross-section. For comparison in the simplified analysis of the ratio, MEd/MRd is equal 0.76. It is clearly visible the methods requiring more computational effort give lower values of element effort and allows the design to be more economical. As the strengthening fulfills the ultimate limit state, it does not meet the serviceability limit state.
Assessment of the properties of mortars made of sorel cement
Authors: Kotwa Anna , Kłak Adam
Published: June 2024

The purpose of laboratory tests was to determine the effect of sodium silicate and selected hydrophobic agents on the basic physical parameters and freeze-thaw durability of mortars made with Sorel cement in variable proportions. In order to determine the mortars’ parameters, samples of the dimensions of 4x4x16 cm and boards of the diameters of 1x4x16 cm were prepared. Parameters such as water absorption, capillary absorption, compressive and flexural strength and frost resistance were tested. Mortar supplemented with sodium silicate in the quantity of 2.6% of all components demonstrated the best properties. None of the other hydrophobic agents that were used to mitigate the negative effects of water on Sorel cement mortars demonstrated such positive properties. Flexural strength tests of all mortar batches, performed on cuboid samples and boards of the thickness of 1 cm, demonstrated a similar improvement in strength. The lowest value of compressive strength was recorded for the reference batch at 46.6 MPa, whereas the highest value was recorded for the second batch containing sodium silicate, at 49.8 MPa. During the testing of frost resistance, the lowest reduction of compressive and flexural strength was recorded for the reference mortar and for mortar with sodium silicate. All mortars were varied in the MgO/MgCl2 ratio and the total amount of water, the observed effects may be caused by other variables. However it is possible to notice the positive effect of selected hydrophobic agents.
Properties of one-part CaO–Na2CO3 activated ground granulated blast furnace slag
Authors: Li Qian
Published: June 2024

In this study, the fresh and hardened performance and durability of one-part ground granulated blast furnace slags (GGBFS) activated by solid CaO and Na2CO3 were discussed, and their hydration process and microstructure development were analyzed accordingly. Results showed that when the water-to-binder ratio was 0.32, the alkali-activated slag (AAS) paste exhibited lower flowability, higher yield stress and plastic viscosity. As the content of CaO and Na2CO3 increased, the yield stress, plastic viscosity, and compressive strength of AAS after hardening all increased. For the durability of the hardened sample, AAS with high content of activator have higher shrinkage strain and chloride ion flux. The microscopic analysis results indicated that AAS containing CaO and Na2CO3 exhibited more intense hydration heat release and rapid microstructure development in the early stage, thereby promoting the improvement of strength. The use of CaO and Na2CO3 to activate GGBFS has enormous application potential in solid waste utilization and carbon emission reduction, which can reasonably replace traditional Portland cement (PC) as a new generation of sustainable cementitious materials.
Buttress wall in limiting wall deformation caused by deep excavation: A case study for colluvial soil in Vietnam
Authors: Bui Luc Manh , Wu Li , Do Minh Ngoc , Cheng Yao , Dong Dao Jun
Published: June 2024

The objective of this study is to assess the impact of utilizing a BW (Buttress wall) to control the deflection of a diaphragm wall in colluvial soil conditions in Vietnam. The physical and mechanical properties of the colluvial layers are evaluated using data closely monitored during a specific project, serving as validation for 3D numerical simulations utilizing the Hardening Soil Model. The analysis results closely match the field monitoring data, which has tested the accuracy of the simulation model. This forms the basis for further investigations into the dimensional parameters of BW walls, including length, thickness, and spacing between them. The results obtained from the parametric study demonstrate that altering the wall length and spacing between BWwalls significantly limits the deflection of the diaphragm wall, while changes in thickness have a negligible effect. Through the 3D numerical simulations, a linear relationship between the maximum wall deflection and parameters such as wall length and spacing between BW walls has been established.
Parametric optimization scheme of energy dissipation and shock absorption for prefabricated concrete frame
Authors: Li Zhengjian
Published: June 2024

The prefabricated concrete frame structure system has advantages such as short construction period and good seismic performance, but its deformation and energy dissipation capacity are poor under earthquake action, making it prone to damage. By improving the analysis and simulation functions of existing finite element analysis for prefabricated structures, the engineering applicability of the analysis algorithm has been improved. Then, a finite element model has been established for collaborative optimization, and a parameterized optimization scheme that meets the seismic reduction requirements has been obtained. The results show that the optimization method proposed in the study has a better effect in seeking the minimum cost, and meets the design requirements of the specification. The optimization scheme of prefabricated concrete frames designed by the research institute based on finite element analysis can efficiently optimize various parameters, greatly improving the structure energy dissipation and seismic performance.
Research on construction monitoring of curvilinear continuous beam bridge jacking and horizontal moving construction
Authors: Zheng Xilong
Published: June 2024

This article investigates the issue of beam misalignment in continuous curved beam bridges. Taking the D0–D6 spans of the Gongbin Road elevated bridge as a basis, real-time monitoring of the stress and displacement of the beams is carried out during the jacking and shifting construction process. At the same time, the reaction forces of each support are monitored. The jacking force of the hydraulic jacks is controlled to ensure the stability and safety of the beam during the construction process. Finally, the jacking and shifting monitoring data is organized and compared with theoretical values. It is found that the stress values generated during the jacking phase of the bridge are below the stress control standard. No uplift phenomenon occurs at the supports, and the jacking height is controlled within a reasonable range. The construction process does not cause damage to the beams, and it is safe and reliable. During the shifting construction, the whole bridge was displaced using the jacking method, and the three working conditions were monitored throughout the process. The stress increment at the 2# and 4# sections was relatively small, and the measured stress increments for the entire bridge were all below the stress control standard. The displacement of the bridge abutment during the jacking process was minimal, with no contact with the abutment blocks, and no significant elastic deformation occurred. The jacking displacement was successfully achieved.

Authors: Corona Jiménez Miguel Ángel
Published: June 2024

Objetivo: dilucidar si el gobierno del presidente López Obrador se ha dirigido a cambiar el proyecto de nación desde la esfera económica, planteando una modernización del capitalismo con progreso social y regional. Metodología: se realiza un análisis comparativo, considerando tres etapas: La etapa de 1934-1982, caracterizada por una fuerte intervención del Estado en la economía. La etapa de 1983-2018, caracterizada por un predominio del mercado, y la etapa de 2019-2021, caracterizada por regresar al estado fuerte en la sociedad. Resultados: Los resultados permiten observar que, en los primeros tres años del gobierno de López Obrador, se ha realizado un intento por modificar la orientación del crecimiento económico. Esta nueva iniciativa incluye acciones económicas para beneficiar a los grupos más desfavorecidos, inversiones en sectores estratégicos sobre todo en el sureste del país, con disciplina fiscal; mientras una pandemia ocurría y los grupos de poder de oposición ejercían constante presión. Limitaciones: Los resultados tienen la limitante de corresponder a una mitad de sexenio, por lo que se presentan de manera preliminar.

Many music events, be it concerts or festivals, are being held worldwide, and Indonesia is one of them. Motivation to attend a music festival is an experience that is a balance between fun, self-reflection, and impact. Our objective is to investigate how event experience helps shape satisfaction and, in turn, leads to future behavioural intention. This study uses Partial Least Squares regression to investigate six hypotheses. A total of 206 individuals in Indonesia who attended concerts in the past six months were surveyed, with 150 valid responses, giving a 72.8% response rate. The result shows that event experiences that are escapism, entertainment, and esthetic factors positively affect consumer satisfaction among music festivals and concert attendees, with the exception of education. Furthermore, consumer satisfaction significantly increases the tendency to both recommend and revisit. Thus, this study shows that event organizers need to create a memorable experience to gain favourable behavioural intention.
