AbstractIn the modern era, intensive agricultural practices such as agrochemicals are applied in excessive amounts to enhance agricultural production. However, imbalanced adoption of these chemicals has arisen in the dwindling of agriculture factor productivity and soil quality. To maintain soil fertility and production, these chemical fertilizers must be supplemented with organic inputs. Keeping this in the backdrop, a research trail was established during 2018–19 and 2019–20 years at Research Farm of Agriculture University, Kota, India. The treatment setup was comprised of 5 treatment modules viz., conservation tillage + organic management (CAOM), conservation tillage + chemical management (CACM), conventional tillage + chemical management (CTCM), conventional tillage + organic management (CTOM) and the package of practices (PoPs) with four replications. Results indicated that the highest organic carbon (0.68%), bacterial (29.11 × 107 cfu g−1), fungal (4.77 × 104 cfu g−1), actinomycetes populations (5.67 × 104 cfu g−1), acid phosphatase (44.1 µg g−1 h−1), urease (45.3 µg g−1 h−1) and dehydrogenase (23.3 µg triphenylformazan [TPF] g−1 h−1) activity in soil were found in the treatment of conservation organic system during both the years of study at each soil depth. In contrast to other parameters, the highest system productivity was observed with conservation chemical crop management approaches, with a soybean equivalent yield of 4615 kg ha−1 in a soybean–wheat system of production. Furthermore, the soil quality index (SQI) significantly varied from the lowest score (0.30) at 45–60 cm layer of soil in the package of practices to the highest score (0.92) at 0–15 cm layer of soil with regards to the conservation organic which shows, 206.67 percent enhancement through the soil profile of various crop management practices. The SQI variation from 0–15 to 45–60 cm soil depth was 130.0, 81.08, 60.0, 175.0 and 83.33 percent, respectively, for CAOM, CACM, CTCM, CTOM and PoPs. Amongst, different systems, the highest mean performance was noticed under the conservation organic systems for physical and biological properties. Hence, in line with the salient outcome, we may propose that the conservation chemical system needs to be followed to improve crop productivity, whereas, conservation organic seems a good option for soil health with long-term viability.

AbstractSurfaces on transit vehicles are frequently touched and could potentially act as reservoirs for micro-organism transmission. Regular cleaning and disinfection to minimize the spread of micro-organisms is operationally challenging due to the need to keep vehicles in circulation. The application of copper (Cu) alloys to high- touch surfaces could help reduce the risk of cross-contamination, however, little is known about the durability and efficacy of engineered copper surfaces after prolonged use. Three Cu products (decal, thermal fabrication, and alloy covers) were assessed over a 12-month period. These Cu products were randomly installed on 110 stanchions on three buses and four train (SkyTrain) cars in Vancouver and three buses, two subway cars, and two streetcars in Toronto with mirrored control surfaces directly opposite. Bacterial counts (Colony forming units, CFU) and ATP bioluminescence (ATPB) were measured every two months after peak morning routes. Durability of the Cu products were assessed monthly through visual inspection and colorimetry assays or by ex-situ microscopy. Cu products on stanchions reduced the mean colony forming units (CFU) of all vehicles by 42.7% in the mean CFU (0.573 (CI 95% 0.453–0.726), p-value < 0.001) compared to control surfaces. The three Cu products exhibited an overall 87.1% reduction in the mean ATPB readings (0.129 (CI 95% 0.059–0.285, p-value < 0.001) compared to controls. Surface Cu concentration for all three products was consistent throughout the 12-month period. Electron microscopy (SEM) and Energy-dispersive X-ray Spectroscopy (EDS) cross-sectional analysis showed no change in thickness or dealloying of Cu products, however SEM top-down analysis revealed substantial carbon accumulation on all surfaces. Cu products installed on transit vehicles maintained antimicrobial efficacy and durability after 12 months of use.

AbstractThe particle breakage effect and compression characteristics of calcareous sand are related to the water content in the sand material. However, the effects of water content on the particle breakage and compression characteristics of calcareous sand have rarely been investigated. In this work, 50 sets of confined compression tests were conducted on calcareous sand specimens, and the compression characteristics and particle breakage effects of two single-particle-size groups (particle size ranges of 1–0.5 mm and 0.5–0.25 mm) of calcareous sand were investigated under five different water contents. The test results showed that with the increase in the water content, the final compression deformation of calcareous sand was positively correlated with the water content. The final compression deformation decreased when the water content reached a certain value. The water content corresponding to the peak final compression deformation was related to the gradation of the calcareous sand; the specific values were 10% and 15% for particle size ranges of 1–0.5 mm and 0.5–0.25 mm, respectively. With the increase in the water content, the slope of the loading curve of calcareous sand appeared to increase and then decrease, reaching maximum when the water content was 10%. Moreover, the slope of the loading curve was close to twice that of the loading curve of dry sand, whereas the slope of the unloading curve changed little. Under the same water content, the initial gradation had no effect on the compression and unloading characteristics of the specimens beyond a vertical pressure of 1 MPa. The effects of the variation in the water content on the particle breakage of calcareous sand were mainly reflected in the softening effect of water on the specimen particles, which reduced the Mohr strength of the particles.

Resumo
Objetivo: Testar a diferença do comportamento de distribuição de cargas e pressões da placa lâmina comparativamente com a placa bloqueada para osteotomia varizante do fêmur proximal através do método de elementos finitos.
Métodos: A modelagem foi realizada através do escaneamento de um fêmur esquerdo com deformidade medial em valgo fabricado em poliuretano de tamanho médio.
Resultados: Como resultados, pode-se inferir que a rigidez da placa bloqueada é maior do que a da placa lâmina. No entanto, essa diferença não foi significativa e, além disso, a placa bloqueada possui parafusos de travamento proximal para garantir que os momentos de flexão que agem nos parafusos sejam ainda menores durante o carregamento.
Conclusão: Em síntese, ambos os materiais são consagrados e eficazes para serem utilizados, porém o estudo pelo método de elementos finitos apresenta papel importante para compreendermos a situação de distribuição de cargas e pressões do implante e abre novas possibilidades para novos estudos, como, por exemplo, o estudo da proposta cirúrgica e materiais a serem implantados de forma individual e personalizada.

Resumo
Objetivo: Comparar a função e a força muscular do membro entre pacientes submetidos a artroplastias do joelho que utilizaram implantes primários com estabilização posterior (grupo controle) e pacientes com implantes constritos rotatórios (grupo Hinge).
Métodos: A avaliação da função foi feita por meio do Knee Society Score (KSS) e da força muscular por um dinamômetro isocinético utilizando a velocidade de 60°/s.
Resultados: Foram analisados 43 pacientes, que realizaram 51 cirurgias, sendo o grupo Hinge composto por 25 cirurgias e o grupo controle por 26 cirurgias primárias. Não observamos diferenças significativas entre os grupos Hinge e controle nos valores do KSS funcional (p = 0,54), KSS objetivo (p = 0,91), pico de torque flexor (p = 0,25) e pico de torque extensor (p = 0,08). Os pacientes do grupo Hinge que realizaram artroplastias primárias apresentaram um pico de torque flexor maior (0,76 Nm/kg) que aqueles que utilizaram o implante em revisão após falha séptica (0,33 Nm/kg) (p < 0,05). O implante constrito foi indicado em cirurgias de revisão de artroplastia com instabilidade ligamentar grave e em casos de artroplastias primárias complexas com destruição óssea ou deformidade coronal grave no plano coronal.
Conclusão: O uso de implantes bloqueados possibilita função articular e força muscular comparáveis a dos pacientes que realizaram artroplastia primária utilizando implantes convencionais com estabilização posterior. Pacientes submetidos à revisão séptica com prótese Hinge rotatória apresentam menor força da musculatura flexora em relação àqueles submetidos a artroplastia primária com implante constrito.

AbstractAs a double-edged sword, the Internet is prone to breed cyber violence and bullying on the one hand, on the other hand, it can promote the expansion of altruistic behavior in cyberspace. Exploring the mechanism of generating Internet altruistic behaviors can help improve adolescents’ adaptive development and build a harmonious online environment. In light of this, this study constructed a hypothetical model of parental emotional warmth and adolescents’ Internet altruistic behaviors with gratitude trait as the mediating variable and belief in a just world as the moderating variable, in order to investigate how personal experiences, personality, and social cognition affect the practice of Internet altruistic behavior. A total of 1004 adolescents from two middle schools in China were selected for the survey. The results showed that parental emotional warmth significantly and positively affects adolescents’ Internet altruistic behaviors, while gratitude mediated this path between the two, with the mediating effect accounting for 27.07% and 24.27% of the total effect in the model of paternal and maternal emotional warmth, respectively. Moreover, in the paternal emotional warmth model, this indirect effect was moderated by belief in a just world, and the indirect effect was stronger for adolescents with lower beliefs in a just world relative to those with higher beliefs. Relative to paternal emotional warmth, belief in a just world was not significant in moderating the indirect effects of maternal emotional warmth on Internet altruistic behavior through gratitude. This research aims to provide more empirical research on the mechanisms of adolescents’ Internet altruistic behaviors and to provide more insights into the promotion of responsible and appropriate Internet use among adolescents.

Published: March 2024

Context The ban on antibiotics in broiler feed has led to the need for alternative additives that can be used in poultry production, particularly in tropical climates where animals experience high levels of stress. A capsicum extract (CE), derived from chili peppers, is a potential feed additive that may enhance the performance of broiler chickens. Aims This experiment investigated the effects of CE on the growth performance, blood parameters, and intestinal bacterial population of broilers raised under high stocking density in a tropical region. Methods Four hundred and thirty-two 1-day-old Ross-308 male broiler chicks were divided into six treatments, each with six replicate pens of 12 birds. The experiment followed a randomised complete-block design. Feeding was conducted for 38 days in the following three phases on the basis of breeder recommendations: starter, grower, and finisher. CE was supplemented in the feed at concentrations of 80, 160, 240, and 320 mg/kg. All feeds were pelleted to different sizes for each phase. Growth performance was assessed at the end of each phase. Blood samples were collected to determine the complete blood count (CBC) and serum growth-hormone concentration. Chicks were euthanised using CO2 inhalation, and samples from the jejunum were collected for histological analysis. The caecocolonic contents were sampled for microbiological testing. Key results CE supplementation at concentrations of 160 and 240 mg/kg improved the performance of broilers equivalent to enramycin supplementation at 250 mg/kg, with additional benefits observed in water intake when supplemented at 240 mg/kg. The slight improvement in villous height may have contributed to the enhanced growth performance. Both the lowest (80 mg/kg) and highest (320 mg/kg) supplemented concentrations of CE slightly improved broiler performance compared with the control group. The lowest dose of CE also had a beneficial effect in reducing the E. coli:Lactobacillus ratio. Conclusions It is concluded that CE supplementation may improve performance of broilers under moderate heat-stress conditions by increasing feed and water intake with an enhanced bodyweight gain. Implications A capsicum extract can be used as an antibiotic alternative in broiler production in hot tropical environments.
Hospital admissions to Phillip Island Wildlife Clinic, Victoria, Australia, over a 10-year period, 2012–2021
Authors: Dutton-Regester Kate J. 
Published: March 2024

Wildlife clinics play a critical role in safeguarding the well-being and survival of diverse animal species, but their admissions data are also valuable for investigating threats and challenges impacting local wildlife. This study examines 10 years of admissions data from the Phillip Island Wildlife Clinic in Victoria, Australia, to identify species, primary causes, outcomes, and temporal trends of clinic admissions. Avian species constitute the majority of admissions (64.5%), with sea and water birds being the most frequently admitted group. Motor vehicle accidents, injuries of unknown cause, and orphaning are the dominant causes of admission for birds and mammals. Car strikes are the leading cause of admission for land birds, land mammals, macropods, and turtles. Orphaning exhibits a seasonal pattern, with a higher number of cases in spring. Overall, 59.1% of admissions resulted in mortality, with causes related to trauma showing significantly higher mortality risks than others. The findings emphasise the impact of tourism on wildlife populations and the urgent need for targeted conservation strategies on Phillip Island.

Abstract
Photovoltaic solar cells (PVSC) with Molybdenum telluride (MoTe2) have received considerable attention because of their wide range of absorption, along with the absence of dangling bonds at their surface. Here, MoTe2-based PVSC with a preliminary device structure of Al/ITO/n-MoSe2/p-MoTe2/Pt was designed and estimated its performance by using the solar cell capacitance simulator in one dimension software program (SCAPS-1D). The effect of different parameters like thickness, doping density, and interface defect density of each layer was also investigated. Our investigation reveals that a moderate thickness of ∼1000 nm of MoTe2 and 500 nm of MoSe2, a higher concentration of more than 1017 cm−3 for both layers and moderate defect density of below 1014 cm−3 are favorable for the better PVSC device.

Our analysis shows that minimum series resistance, higher shunt resistance, lower working temperature, and a high back-metal work function of more than 5.35 eV are advantageous for superior PVSC due to low recombination losses, low electrical losses, and better transport of charge carriers. The best performance of 28.75% with Jsc of 34.11 mA cm−2, Voc of 0.98 V, and FF of 86.3%, was achieved by optimizing all parameters.

A novel chaotic image encryption is based on fractional wavelet decomposition and quantum transform model
Authors: Yan Xiaopeng , Teng Lin , Su Yining 
Published: March 2024

Abstract
A new chaotic image encryption scheme based on fractional order wavelet decomposition is proposed in this paper. Initially, the image undergoes a three-stage fractional-order wavelet decomposition, resulting in high-frequency and low-frequency components. High-frequency components are dislocated using a chaotic system, while low-frequency components are dislocated employing a fractional matrix model. Subsequently, the scrambled image undergoes quantum encoding followed by the Arnold transform to yield the final scrambled result. Ultimately, the encryption process involves iteratively acquiring the M4 key matrix and diffusing the quantum image through permutation to obtain the final encryption result. Simulation experiments and numerical analyses demonstrate the high security level of the proposed encryption method.

Abstract
In this work, a modified Ronchi tester with a double light source has been implemented for evaluating and minimizing the rotation angle of the Ronchi ruling. The ruling rotations produced by positioning errors can become very small and could be going unnoticed (0.1°), however we have demonstrated that for these angle sizes the aberrations in the wavefront can not be completely neglicted. Accordingly with a rotatory mechanical device for correctioning the Ronchi ruling has been also added with this proposals. With our aim, in spite of non-straight shape that the ronchigrams can present in the patterns, the process of the ruling rotation degree measuring has hurled some experimental results when three concave mirrors: a concave spherical mirror, a concave parabolic mirror (the primary mirror of a Newtonian telescope) and a spherical concave mirror (the primary mirror of a Maksutov-Cassegrain telescope) have been tested.
fkPT: constraining scale-dependent modified gravity with the full-shape galaxy power spectrum

Published: March 2024

Abstract
Modified gravity models with scale-dependent linear growth typically exhibit an
enhancement in the power spectrum beyond a certain scale. The conventional methods for extracting
cosmological information usually involve inferring modified gravity effects via Redshift Space
Distortions (RSD), particularly through the time evolution of fσ
8. However, classical
galaxy RSD clustering analyses encounter difficulties in accurately capturing the spectrum's
enhanced power, which is better obtained from the broad-band power spectrum. In this sense,
full-shape analyses aim to consider survey data using comprehensive and precise models of the
whole power spectrum. Yet, a major challenge in this approach is the slow computation of
non-linear loop integrals for scale-dependent modified gravity, precluding the estimation of
cosmological parameters using Markov Chain Monte Carlo methods. Based on recent studies, in this
work we develop a perturbation theory tailored for Modified Gravity, or analogous scenarios
introducing additional scales, such as in the presence of massive neutrinos. Our approach only
needs the calculation of the scale-dependent growth rate f(k,t) and the limit of the
perturbative kernels at large scales. We called this approximate technique as fk-Perturbation
Theory and implemented it into the code fkpt, capable of computing the redshift space
galaxy power spectrum in a fraction of a second. We validate our modeling and code with the
f(R) theory MG-GLAM and General Relativity NSeries sets of simulations. The

Published: March 2024

Abstract
We study the dynamics of the critical collapse of a spherically symmetric scalar field. Approximate analytic expressions for the metric functions and matter field in the large-radius region are obtained. In the central region, owing to the boundary conditions, the equation of motion for the scalar field is reduced to the flat-spacetime form.
