Childhood and puberty can affect metabolism, leading to tissue injury and malfunction later in life. The consumption of high-processed foods rich in salt and sugar is increasing in middle- and high-income countries, especially among young people. It is necessary to evaluate the effects of high salt and sugar levels in the youth on most injured organs during metabolic challenges. We aimed to investigate whether high-salt/sucrose intake affects whole-body development and leads to end-organ injury. Weaned male Wistar rats were divided into two groups: a control group fed a standard diet and tap water, and an experimental group (SS) fed a standard diet and a beverage containing 1·8 % NaCl and 20 % sucrose instead of tap water. The animals were treated for 60 d, starting after weaning at 21 d of age, after which the animals were subjected to glucose and insulin tolerance tests, urine collection and heart rate monitoring and euthanised for sample collection at 81 d of age. SS showed reduced body weight gain and increased food intake of sodium/sucrose solution. Interestingly, high-salt/sucrose intake led to increased body adiposity, liver lipid inclusion, heart rate and renal dysfunction. SS exhibits increased levels of PPAR alpha to counterbalance the hypertrophy of brown adipose tissue. Our findings reveal that the SS rat model exhibits non-obvious obesity with end-organ damage and preserved brown adipose tissue function. This model closely parallels human conditions with normal BMI but elevated visceral adiposity, providing a relevant tool for studying atypical metabolic disorders.
The concurrent challenges of the COVID-19 pandemic and a significant earthquake in Izmir on October 30, 2020, presented a unique scenario for disaster management and response. This study focuses on the impact of the earthquake, which resulted in 117 fatalities, including 1 due to drowning, and injured 1034 individuals, alongside widespread structural damage including to the Izmir Democracy University Buca Seyfi Demirsoy Training and Research Hospital. The objective is to assess the activation and implementation of the hospital disaster plan amidst the ongoing pandemic. Through a retrospective evaluation of all actions undertaken as per the Hospital Disaster Emergency Plan within the Disaster Management cycle, this study examines the decision-making process for the hospital evacuation on October 30, 2020, the evacuation of COVID-19 patients, and the strategies employed to increase hospital capacity. Of 216 patients hospitalized at the time of the earthquake, 65 were transferred to other facilities under COVID-19 protocols. The prolonged nature of pandemics and the likelihood of secondary disasters underscore the importance of comprehensive risk assessments and dynamic disaster planning, considering simultaneous multiple hazards. This study suggests the inclusion of multi hazard scenarios and diverse evacuation methods by using types of ambulances, such as ground, helicopter, and boat.
Stratified wakes past an isolated conical seamount are simulated at a Froude number of $Fr = 0.15$ and Rossby numbers of $Ro = 0.15$, 0.75 and $\infty$. The wakes exhibit a Kármán vortex street, unlike their unstratified, non-rotating counterpart. Vortex structures are studied in terms of large-scale global modes, as well as spatially localised vortex evolution, with a focus on rotation effects. The global modes are extracted by spectral proper orthogonal decomposition (SPOD). For all three studied $Ro$ ranging from mesoscale, submesoscale and non-rotating cases, the frequency of the SPOD modes at different heights remains coupled as a global constant. However, the shape of the SPOD modes changes from slanted ‘tongues’ at zero rotation ($Ro=\infty$) to tall hill-height columns at strong rotation ($Ro=0.15$). A novel method for vortex centre tracking shows that, in all three cases, the vortices at different heights advect uniformly at approximately $0.9U_{\infty }$ beyond the near wake, consistent with the lack of variability of the global modes. Under system rotation, cyclonic vortices and anticyclonic vortices (AVs) present considerable asymmetry, especially at $Ro = 0.75$. The vorticity distribution as well as the stability of AVs are tracked downstream using statistics conditioned to the identified vortex centres. At $Ro=0.75$, intense AVs with relative vorticity up to $\omega _z/f_{c}=-2.4$ (where $\omega_z$ is the vertical vorticity and $f_c$ is the Coriolis frequency) are seen with small regions of instability and they maintain large $\omega _z/f_{c}$ magnitude in the far wake. Recent stability analysis that accounts for stratification and viscosity is found to improve on earlier criteria and show that these intense AVs are stable.
The fruit fly Ceratitis capitata is a successful generalist due to the trade-off between different variables in its life history traits. The present study aimed to assess some life history traits of C. capitata recovered from peach, plum and fig, three key host species, under the climatic conditions of an irrigation oasis in the arid province of San Juan, Argentina. Pupal abundance, sex ratio and morphometric parameters such as pupal and adult weight, pupal volume, wingspan and head-caudal length were influenced by the host in which the larvae were reared. Sexual maturity, measured as the peak of calling (pheromone emission), was homogeneous on the sixth and seventh days after emergence, but males recovered from fig showed early calling activity on the third day after emergence. The plasticity of C. capitata to adapt its life history traits to specific nutrient variations within the larval environment allows it to colonise and establish populations where key hosts, as those studied here, are available. The knowledge of the interactions between host fruit trees and C. capitata populations provides helpful information for planning the management of local orchards and urban fruit plantations within irrigation oases, taking into consideration the concept of key hosts as peach and fig.
In a context promoting partners’ active participation in their divorce or dissolution, family lawyers often put their clients to work – from stating goals and supplying information for the written file, to embodying the case at the hearing. This article focuses on the coproduction of legal work between family lawyers and their clients, based on long-term collective research on family law in mainland France: interviews with attorneys, observations of encounters between lawyers and clients in lawyer offices and in courts, as well as a “3,000 family cases” database. Using a relational, materialist, structural, and intersectional theoretical approach, we show that coproduction of legal work and its meaning varies greatly depending on the power dynamics between lawyers and clients, – on a spectrum that goes from exploitation to empowerment of the client. Coproduced legal work varies according to configurations of class, race, gender, and age on both side of the desk, as well as according to the structure of the legal market. Interactions between lawyers and their clients thus contribute to shape inequality before the law.
A novel theoretical model for bubble dynamics is established that simultaneously accounts for the liquid compressibility, phase transition, oscillation, migration, ambient flow field, etc. The bubble dynamics equations are presented in a unified and concise mathematical form, with clear physical meanings and extensibility. The bubble oscillation equation can be simplified to the Keller–Miksis equation by neglecting the effects of phase transition and bubble migration. The present theoretical model effectively captures the experimental results for bubbles generated in free fields, near free surfaces, adjacent to rigid walls, and in the vicinity of other bubbles. Based on the present theory, we explore the effect of the bubble content by changing the vapour proportion inside the cavitation bubble for an initial high-pressure bubble. It is found that the energy loss of the bubble shows a consistent increase with increasing Mach number and initial vapour proportion. However, the radiated pressure peak by the bubble at the collapse stage increases with decreasing Mach number and increasing vapour proportion. The energy analyses of the bubble reveal that the presence of vapour inside the bubble not only directly contributes to the energy loss of the bubble through phase transition but also intensifies the bubble collapse, which leads to greater radiation of energy into the surrounding flow field due to the fluid compressibility.
We study the exact Hausdorff and packing dimensions of the prime Cantor set, $\Lambda _P$, which comprises the irrationals whose continued fraction entries are prime numbers. We prove that the Hausdorff measure of the prime Cantor set cannot be finite and positive with respect to any sufficiently regular dimension function, thus negatively answering a question of Mauldin and Urbański (1999) and Mauldin (2013) for this class of dimension functions. By contrast, under a reasonable number-theoretic conjecture we prove that the packing measure of the conformal measure on the prime Cantor set is in fact positive and finite with respect to the dimension function $\psi (r) = r^\delta \log ^{-2\delta }\log (1/r)$, where $\delta $ is the dimension (conformal, Hausdorff, and packing) of the prime Cantor set.
Anaemia affects more than 36 % of all pregnancies globally and is associated with significant maternal and neonatal morbidity and mortality. Iron deficiency is widely recognised as the most common nutritional cause of anaemia but other nutrient deficiencies are also implicated, including the B vitamin riboflavin, albeit its role is largely under-investigated and thus typically overlooked. Riboflavin, in its co-factor forms flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), is required for numerous oxidation-reduction reactions, antioxidant function and in the metabolism of other B vitamins and iron. While clinical deficiency of riboflavin is largely confined to low-income countries, sub-clinical (functional) deficiency is much more widespread, including in high-income countries, and is particularly common among women of reproductive age and during pregnancy. Limited observational evidence from high-income populations suggests that suboptimal riboflavin status contributes to an increased risk of anaemia. Furthermore, randomised controlled trials in pregnant women from low- and middle-income countries have demonstrated beneficial effects of riboflavin on haematological status and anaemia. Various mechanisms have been proposed to explain the contribution of riboflavin deficiency to anaemia, with the strongest evidence pointing to an adverse effect on iron metabolism, given that riboflavin co-factors are required for the release of iron from storage ferritin in the production of red blood cells. Overall, this review investigates riboflavin intakes and status during pregnancy in different populations and evaluates the available evidence for the under-recognised role of riboflavin in the maintenance of haemoglobin concentrations together with its potential to protect against the development of anaemia during pregnancy.
Graffiti are often seen as providing a window into the emotions of ancient peoples. However, Byzantine graffiti has been viewed as an exception, with the formulaic Greek texts written between 300 and 1500 taken as evidence of communal identity, rather than individual expressiveness. However, variations in these texts can reveal much about an individual author and their personal experiences. In particular, certain formula suggest the dangerous situation an author survived, including incarceration and sea travel. This paper focuses on Corinth, Syros, and Tinos where individuals experienced danger, and how their fears and needs were manifested in the graffiti they left behind.
How does interior immigration enforcement affect how undocumented immigrants describe their interactions with state and societal institutions? Although there is some evidence that points to a broad range of chilling effects that result when local law enforcement officials work with U.S. Immigration and Customs Enforcement (ICE) on federal immigration enforcement, there is no systematic study that collectively examines the impacts that may result with such enforcement efforts. We situate our paper as evidence of the homeland security state and show how contemporary interior immigration enforcement subjugates undocumented immigrants in nearly all facets of their interactions with state and societal institutions. To illustrate this, we embedded an experiment in a survey (n = 594) drawn from a probability-based sample of undocumented immigrants. When respondents are told that local law enforcement officials are working with ICE on federal immigration enforcement, they report that they would be less likely to report crimes they witness or are victims of to the police, use public services that require them to disclose their personal contact information, do business that requires them to disclose their personal contact information, and participate in public events where the police may be present, among other main findings.
The Taylor–Maccoll (T–M) equations are the governing equations for steady inviscid irrotational axisymmetric conical flow, and have been widely applied to the design of waveriders and intakes. However, only four classic solutions have been reported: external conical flow (ECF), Busemann flow and internal conical flow of types A and B (ICFA and ICFB). In this work, the analysis of the T–M equations clarifies all possible solutions and reveals their relations. The domain where elementary solutions exist is divided into four domains. The classic Busemann and ICFB solutions share the same elementary solution as the template in a domain called the pre-shock domain, while the classic ECF and ICFA solutions belong to a domain named the ECF domain. Two new solutions, the inner flow of ECF (IECF) and degenerate conical flow (DCF), are found in the domains named after the corresponding solutions, namely the IECF and DCF domains. The IECF behaves as the mass injection supporting the classic ECF on an imaginary cone surface, while the DCF behaves as the conical expansion of a uniform flow. Furthermore, possible combinations of pre-shock solutions and supersonic post-shock solutions are clarified. The classic solutions are special cases where the pre-/post-shock solutions are combined with uniform flows. In general, the Busemann and ICFB solutions can be combined with any post-shock solutions in accord with the shock relations, including the ECF, ICFA, IECF and DCF solutions. In addition, numerical analyses are conducted to verify the validity of the two new solutions, DCF, IECF and one combined solution Busemann–ECF.
You can never really get tired of Italian politics. Over the last 30 years, we have seen many turning points, the most memorable of which was undoubtedly Silvio Berlusconi's unexpected ‘descent into the field’ in 1994. Nor have we been deprived of colourful characters, such as Matteo Renzi or Matteo Salvini, who, as their careers took off, ended up burning their wings. And after many unsuccessful attempts, imagination has finally come to power (as they used to say in the 1960s), although the 1968 generation has nothing to do with it. Indeed, all the credit goes to the Movimento 5 Stelle (M5S), whose activists were seen carrying their leader Beppe Grillo – sitting in a dinghy – through the streets of Bologna during a procession of sorts. The general elections of 25 September 2022 added an important chapter to recent Italian political history, which has sometimes taken on a dramatic tone but more often that of a comedy or even a farce. All in all, nothing out of the ordinary; in the society of the spectacle, this is how the Darwinian struggle for political survival can also be played out.
A number of important studies have documented gender gaps in the effectiveness or performance of individual representatives. Yet whether these differences are observable when it comes to responsiveness to public opinion is unclear. In this article, I examine the degree to which representatives use social media to dynamically respond to shifts in issue salience among the electorate. After combining nearly 400 bi-weekly repeated public opinion surveys from YouGov asking voters about their issue priorities, I trained a large language model to classify the universe of elected U.S. and UK representatives’ social media messages on Twitter to the same issues. Findings reveal that women representatives demonstrate greater responsiveness than their male counterparts to shifts in issue salience according to both women and men constituents. Despite an overall bias toward male constituents, female representatives play a crucial role in narrowing the gender gap by consistently aligning their attention with the issues prioritized by female constituents. These findings not only contribute to our understanding of elite-voter responsiveness but also underscore the substantive benefits that women representatives provide for all constituents.
Explosive dispersal of granular media widely occurs in nature across various length scales, enabling engineering applications ranging from commercial or military explosive systems to the loss prevention industry. However, the correlation between the explosive dispersal behaviour and the structure of dispersal system is far from completely understood, thereby compromising the prediction of the explosive dispersal outcome resulting from a specific dispersal system. Here, we investigate the dispersal behaviours of densely packed particle rings driven by the enclosed pressurized gases using coarse-grained computational fluid dynamics–discrete parcel method. Distinct dispersal modes emerge from the dispersal systems with vastly varying sets of the macro- and micro-scale structural parameters in terms of the dispersal completeness and the spatial uniformity of the dispersed mass. Further investigation reveals the variation in the dispersal modes arises from the collective effects of multiscale gas–particle coupling relationships. Specifically, the macroscale coupling dictates the cyclic momentum/energy transfer between gases and particle ring as an entirety. The mesoscale coupling relates to the inter-pore gas filtration through the thickness of the particle ring, leading to the mass/energy reduction of the explosive source. The microscale coupling involves the individual particle dynamics influenced by the local flow parameters. A persistent macroscale coupling results in an incomplete dispersal which takes the form of an aggregated annular band, whereas the meso- and micro-scale couplings alter the macroscale coupling to a different extent. By incorporating the effects of the variety of structural parameters on the multiscale gas–particle coupling relationships, a non-dimensional parameter referred to as the modified mass ratio is constructed, which shows an explicit correlation with the dispersal mode. We proceed to establish a dispersal ring model in the continuum frame which accounts for the macro and meso-scale coupling effects. This model proves to be capable of successfully predicting the ideal and validated failed dispersal modes.
In this essay, I argue for a reinterpretation of F. H. Bradley's theory of feeling based on the underemphasized influence of Hegel's phenomenology on Bradley's philosophy. While traditional interpretations of Bradleyan feeling often understand it to have strong metaphysical connotations, I argue that such interpretations result in an important distortion of the overall structure of Bradley's thought. Contra the metaphysical interpretation, I argue that Bradley's account of feeling can only be properly understood by interpreting his theory in light of his own explicit attributions of the theory to Hegel. By taking Bradley at his word that feeling truly is derived from Hegel, I argue that we are better able to understand the overall structure of Bradley's thought and the way in which he belongs to the neo-Hegelian tradition of philosophy. Through explaining the debt that Bradley owes to Hegel regarding feeling, an important source of disagreement between Bradley and Hegel will become apparent, namely, the ability for feeling to be subsumed within thought, thereby differentiating Bradley's and Hegel's ultimate characterizations of reality.
Cubism graft technique offers controlled thinning of the cartilage and prevents over-curling. This article compares tragal perichondrium with the new cubism graft in tympanoplasty in small- to medium-size tympanic membrane perforations.
Methodology
In our study, we included 40 patients, where tragal perichondrium was used as a graft in 20 patients, while cubism graft with tragal cartilage was used in the other 20 patients.
Results
Only two patients had a failure in graft uptake in the tragal perichondrium group, while three patients had a failure in graft uptake in the group where cubism graft with tragal cartilage was used. Significant closure of the air-bone gap (≥ 9 dB) was observed in post-operative audiogram at three-month follow-up in both groups.
Conclusion
This study concludes that the new cubism graft is comparable to tragal perichondrium graft in terms of graft uptake and closure of the air-bone gap.
