Published: October 2022

Abstract
Foamed concrete (FC) is used extensively in construction, road bases, and tunneling engineering for its light weight, thermal insulation, energy absorption, and deformation capacity. Therefore, its cyclic loads bearing capability after high temperature treatment warrants further investigation. To evaluate the fatigue resistance of high temperature treated FC, incremental amplitude triaxial cyclic compression tests were carried out after four temperature treatments (25°C, 100°C, 200°C, 300°C) under different confining pressures (0 MPa, 0.3 MPa, 0.5 MPa, 0.8 MPa). Based on the stress–strain curve and fracture mode, the peak stress, residual stress, elastic modulus, and brittleness index were analyzed. The damage evolution of FC was analyzed based on hysteretic energy and the failure mechanism was elucidated from the perspective of energy dissipation. In addition, the applicability of the crushable-foam yielding criterion to FC was verified and the strength prediction model of FC was proposed. The results indicate that the fracture pattern of FC is significantly influenced by confining pressure and that the stress–strain curve exhibits strain hardening under high confining pressures. The mechanical parameters of FC are negatively correlated with temperature and positively correlated with confining pressure. The damage evolution consists of three stages and the damage grows slowly in the initial compaction stage. The high confining pressure can restrain the crack development and enhance the elastic strain energy storage efficiency. The crushable-foam yield criterion has good applicability to FC and thermal damage remarkably declines the hydrostatic yield strength of FC.

Abstract
The thermomechanical stress-strain-time behavior of dried sand is of interest. To investigate this, an advanced triaxial loading apparatus that can accurately control the applied loading history was modified to precisely control the temperature surrounding the specimen. A series of special triaxial compression tests were performed using an air-dried sand sample. The test specimens were isotropically consolidated at room temperature, drained heated to different specified temperatures (ranging from 30°C to 60°C, after which they remained constant), and then subjected to drained shear. Various shear loading histories were employed, including (i) continuous monotonic loading; (ii) sustained loading and then cyclic loading with small strain-amplitude; and (iii) stepwise change in the strain rate. Through this study, it was found that the peak and residual shear strengths decrease with increasing temperature. The elastic Young’s modulus increases with increasing stress and decreases with increasing temperature. The creep axial strain increases with increasing stress level and temperature. However, the viscous response by stepwise change in the strain rate is insignificantly affected by increasing temperature.
Drazin Inverse Representation of Idempotent Operators Linear Combination Based on Space Decomposition – An Application for a Smart City
Authors: Luo Wei 
Published: October 2022

Abstract
The idempotent operator in Hilbert space can be decomposed into a linear combination of two idempotent operators, and two idempotent operators are obtained through the decomposition process. The Drazin inverse representation of the linear combination of idempotent operators based on space decomposition is researched in this paper. By using the block operator matrix technique, the infinite-dimensional complex Hilbert space is decomposed to obtain the expression of the Drazin inverse of two idempotent operators P and Q’s multilinear combinations under different conditions.

O Dioctophyme renale é um helminto que habita o tecido renal, é comumente encontrado no rim direito, porém, também pode ser encontrado livremente na cavidade abdominal, no tecido subcutâneo e em outros locais do organismo canino e de outras espécies, incluindo animais silvestres e humanos, caracterizando-se como uma zoonose. O diagnóstico pode ser feito por exame parasitológico da urina, ultrassonografia ou necropsia. O objetivo deste trabalho foi descrever as alterações qualitativas e quantitativas em amostras de urina de cães com D. renale. Foi realizado um levantamento de dados de urinálises de 39 cães com dioctofimatose diagnosticada através de exame ultrassonográfico, que foram atendidos no Hospital de Clínicas Veterinárias, entre os anos de 2013 e 2019. As amostras foram avaliadas no Laboratório de Patologia Clínica Veterinária. A avaliação foi realizada em três etapas: análise física, química e do sedimento. Entre as amostras, a cor mais observada foi a amarela, em 46,15% (18/39), seguida da cor âmbar, em 28,21% (11/39). O aspecto das amostras analisadas foi predominantemente turvo. A densidade urinária apresentou-se entre 1.013 e 1.029 em 43,59% (17/39) das amostras, e maior que 1.030 em 53,85% (21/39). A hematúria foi observada em 66,67% (26/39) das amostras. Cilindros granulosos, leucocitários e hialinos foram observados em 23,08% (9/39) das amostras. Por se tratar de uma doença subdiagnosticada e com sintomatologia inespecífica, os achados da urinálise servem de alerta para o médico veterinário incluir essa doença como diagnóstico diferencial de injúrias renais, uma vez que nem sempre se observam ovos do parasita na urina.

Published: October 2022

In the production and industrialization of cow's milk, an important factor that reduces the quality and quantity of the product is bovine mastitis. The dairy cattle mastitis leads to the use of antibiotics, which indiscriminate and prolonged use is progressively increasing the number of resistant pathogens. In this context, the natural products used to combat pathogenic microorganisms have become an interesting alternative. Among those, propolis stands out on different studies, presenting bacteriostatic and bactericidal properties, being a possible alternative on mastitis control and treatment. To determine that, a series of studies on propolis itself and its compounds properties must be analysed. This work aims to answer if the propolis represents a natural alternative on bovine mastitis’ treatment and control, based on scientific studies analyzing its use against different bacterial species, both in vitro and in vivo.

Animal welfare has become more important as the consumer market is increasingly demanding good conditions of handling production animals, especially in swine farming. There is also scientific evidence of economic losses due to animal stress during growth and before slaughter, reducing body weight, carcass yield and meat quality. Thus, natural and economically viable therapeutic alternatives were researched, such as the use of herbal medicines, aiming to minimize these negative effects on animals. With emphasis on Lippia alba, a plant commonly used in Brazilian medicine with proven efficacy as a relaxant and antiparasitic, anti-inflammatory, anesthetic and anti-stress for most animal species. The aim of this study was to evaluate the effect of L. alba essential oil supplementation on the reduction of serum cortisol levels in growing pigs and as a welfare parameter to evaluate these animals. Twelve F1 castrated pigs with an average weight of 12.3 kg were divided into two groups of six animals. Control group (A1) received saline solution at a dose of 1 mL.kg-1 and treatment group (A2) 0.5% L. alba essential oil at a dose of 1 mL.kg-1 on days 0, 30, 60 and 90 by gavage. During these time points, blood was collected from the auricular vessel to measure cortisol levels using the radioimmunoassay technique (Kit Cort-CT2). The administration of L. alba essential oil showed a significant anti-stress effect in growing pigs, significantly decreasing blood cortisol levels, an indicator of animal welfare.

The registration of political parties participating in the election should pay attention to the perspective of justice both in terms of regulation and practice. In order to participate in the election, a political party must have passed verification by the KPU. The terms of participation of political parties to participate in elections are regulated in Article 173 of Law Number 7 of 2017 concerning Elections. Efforts to obtain fair and equal treatment before the law in the registration of election participants can be seen through several judicial reviews of the Constitutional Court Decisions. This balance of treatment is based on equality of opportunity in the participation of the nation's life as a contribution in the political field according to Article 28D of the 1945 Constitution. Lastly, Decision Number 55/PUU-XVIII/2020 divides the qualifications of political parties as candidates for the 2024 general election into two, namely first, political parties that are only verified administratively, secondly, political parties that are verified administratively and factually. This study aims to describe the requirements for political parties to participate in elections according to the Election Law and the implications of the issuance of the Constitutional Court Decision on the development of the meaning of verification. The writing uses normative research methods. This research will provide findings on the two formulations of the problem and recommendations as conclusions.Keywords: Political Parties; Party Verification; Elections AbstrakPendaftaran partai politik peserta pemilu sudah seharusnya memperhatikan perspektif keadilan baik secara regulasi maupun praktik.

This paper explains the differences in the implementation of financing governance policies at universities that have an impact on the quality of management. The research was conducted on two leading Islamic universities in Indonesia, UIN Syarif Hidayatullah Jakarta and UIN Maulana Malik Ibrahim Malang. This article is based on the hypothesis that the combination of higher education self-financing with stricter restrictions on the state budget has caused higher education institutions to conduct workload studies on internal resources. The management of public service bodies that prioritize the principles of efficiency and productivity is part of a combination hypothesis that requires universities to implement business practices to improve services for the provision of educational services. Through an empirical approach, it was found that there was an increase in compliance with the policies of financing laws and regulations but there were distortions in the policy of centralization and decentralization of financing that had an impact on resource performance.Keywords: Public Service Agency; Financing Management; Islamic State University AbstrakTulisan ini menjelaskan perbedaan implementasi kebijakan tata kelola pembiayaan pada universitas berdampak kepada mutu manajemen.

Introducción: La fauna de sedimentos del subsuelo es donde se da el intercambio entre aguas subterráneas y superficiales, llamada “fauna hiporreica”, cumple funciones ecológicas importantes en ríos, sin embargo, no ha sido estudiada suficientemente en Colombia. Objetivo: Identificar las relaciones entre los invertebrados hiporreicos y variables fisicoquímicas en el río Dagua, Colombia. Métodos: En tres giras a campo (entre octubre 2017 y diciembre 2018) en cinco estaciones de muestreo a lo largo de la cuenca del río, realizamos perforaciones implementando el método de Karaman-Chappuis (sedimento, agua e invertebrados), y registramos la granulometría y materia orgánica en los sedimentos; además, nutrientes, iones y metales en el agua. Resultados: Las estaciones en la zona de cabecera tuvieron sustratos con sedimentos gruesos (grava y piedra), mayores niveles de oxígeno, y menor temperatura del agua. La riqueza y diversidad de especies fueron mayores en estaciones en la zona cabecera, donde predominaron Copepoda e Insecta, mientras que en sitios de cuenca baja predominaron Arachnida (Hydrachnidiae), Clitellata (Oligochaeta) y Nematoda. Conclusiones: La distribución y abundancia de la fauna hiporreica fueron principalmente influenciados por cambios en la granulometría del sustrato hiporreico y sus contenidos de materia orgánica.

AbstractDirofilaria immitis is an endemic mosquito-borne pathogen widely spread throughout Europe as well as North and South America. Infection by D. immitis has been reported in domestic ferrets, although little is known about the occurrence and the epidemiological features of this nematode in this species. The aim of the present retrospective study was to assess the prevalence of D. immitis antibodies using an in-house enzyme-linked immunosorbent assay specifically developed for use in ferrets. One hundred and eighty-six serum samples were obtained from the Province of Valencia (Spain), an area endemic for dirofilariosis. Of the 186 serum samples included in the study, 27 (14.51%) were classified as D. immitis seropositive and 159 samples as D. immitis seronegative. The results provide valuable information on the seroprevalence of D. immitis infection in domestic ferrets in an area endemic for this vector-borne pathogen. The presence of seropositive ferrets should be taken into account and preventive measures should be implemented, including the possibility of serological screening for the early detection of Dirofilaria antibodies as a serological marker of exposure. This is the first study that demonstrates the presence of D. immitis exposure in ferrets in Spain. Veterinarians working in endemic areas should be aware of this infection in ferrets and their susceptibility.
