Utero-Cutaneous Fistula in Ruminants: Characterization of the First Cases in Ewes and Cows

22 Jan 2024  |  MDPI
This report characterizes the first cases of utero-cutaneous fistula (UCF) in ruminants, specifically ewes and cows, contributing to the understanding of this rare condition in pregnant animals. The study details clinical signs, laboratory findings, and follow-up information from four cases over a 12-year period. UCF, a rare consequence of dead fetus retention in end-stage pregnancy, was observed to cause significant health issues, including moderate depression, low feed intake, and weight loss. Surgical interventions varied, with some animals recovering and others succumbing to the condition. The report emphasizes the need for further studies to improve diagnosis and prevention of UCF in ruminants.

A Matrix Transform Technique for Distributed-Order Time-Fractional Advection–Dispersion Problems

25 Aug 2023  |  MDPI
The article presents a novel numerical scheme using the matrix transfer technique to solve the time-fractional advection–dispersion equation (ADE) with distributed-order Riesz-space fractional derivatives. The method reformulates the distributed-order Riesz-space FDs using a second-order linear combination and employs a central difference approximation alongside the matrix transform technique. The distributed-order time-fractional ADE is transformed into a time-fractional ordinary differential equation in the Caputo sense, which is then discretized using the Simpson method. Theoretical stability, convergence, and error analysis are provided, and simulations substantiate the theoretical findings.

Microclimate Multivariate Analysis of Two Industrial Areas

21 Aug 2023  |  mdpi.com
The study analyzes the urban microclimate of industrial districts in Sintra, Portugal, and Uberlândia, Brazil, using the ENVI-met software for computational simulations. It examines variables such as air temperature, humidity, wind speed, and albedo, and their impact on the urban microclimate. The results indicate that despite lower albedo and vegetation in Uberlândia's industrial area, air temperatures may be lower than in Sintra's unshaded surroundings. The study suggests that urban ventilation planning can contribute to sustainable urban development and proposes increasing the albedo of roofs in Uberlândia to potentially decrease air temperatures.

The Climate of My Neighborhood: Households’ Willingness to Adapt to Urban Climate Change

10 Apr 2023  |  MDPI
The study investigates the willingness of residents in the Alvalade neighborhood of Lisbon to adapt their behavior in response to urban climate change scenarios. Using microclimatic modeling with ENVI-met and resident questionnaires, the research reveals that while residents are aware of local climate change and health risks from extreme heat, they are resistant to changing their behavior. The study also finds that residents believe local authorities should take more responsibility for climate change adaptation. The findings highlight the importance of public participation in decision-making processes to mitigate adverse climate effects in urban environments.
