DIAGNÓSTICO SOCIOAMBIENTAL DO ESTADO DE SERGIPE NO PERÍODO ENTRE OS ANOS DE 1991 E 2020
Authors: Lima Rafael Rodrigo Ferreira de , Sousa Inajá Francisco de , Teixeira Antônio Heriberto de Castro 
Published: March 2024

Objetivo: explanar, de forma objetiva, concisa e didática a dinâmica socioambiental do estado de Sergipe no período de 1991 a 2020 de forma a levar o leitor à compreensão do estado fidedigno de tais questões nas três décadas de analisadas.

Referencial Teórico: A busca pela sustentabilidade perpassa pelo entendimento do real estado das questões socioambientais das populações. Para a compreensão desse tipo de entendimento é necessário consolidar o conhecimento construído ao longo do tempo e orientar a execução das metas do desenvolvimento sustentável de forma a corrigir as disparidades históricas existentes na população a partir do seu pleno conhecimento.

Método: A metodologia, descritiva e qualitativa, compreendeu a coleta e análise de dados secundários de plataformas oficiais e públicas do Brasil sobre a área de estudo.

Resultados e conclusões: Verificou-se que a população sergipana passou a viver mais, mas com dificuldades persistentes em infraestrutura e menor disponibilidade de água, paisagem mais antropizada e, portanto, com uma qualidade de vida que não acompanhou o índice de longevidade. Concluiu-se que não se pode afirmar que o estado de Sergipe esteja caminhando para a sustentabilidade, uma vez que os aspectos sociais, ambientais e econômicos não são capazes de promover a justiça socioambiental e a qualidade de vida digna de toda a população..

Implicações da pesquisa: A pesquisa permitiu fornecer um quadro fidedigno, dentro das possibilidades, dos aspectos social, ambiental e econômico do estado de Sergipe ao longo de três décadas. Essa possibilidade permite que novas reflexões e procedimentos acadêmicos e políticos sejam considerados ao buscar o atingimento das metas de Desenvolvimento Sustentável nesse estado brasileiro.

Originalidade/valor: A pesquisa demonstrou sua singularidade ao estudar o recorte temporal entre o fim do século XX e o início do século XXI no estado de Sergipe, em que as discussões e as alterações no modo de viver do ser humano se fazem necessárias em virtude das emergências climáticas.

Published: March 2024

The development of both convective stationary perturbation and global instabilities in the vicinity of a laminar separation bubble above an axisymmetric compression corner in hypersonic flow was investigated using numerical simulations. The flow configuration of interest corresponded to the cone–cylinder–flare model used in experimental measurements in the Boeing/U.S. Air Force Office of Scientific Research Mach-6 Quiet Tunnel (BAMQT) at Purdue University. For a flare angle of 10 deg and unit Reynolds number of [Formula: see text], their surface flow visualizations identified the presence of streamwise elongated thermal streaks near the reattachment location that had a dominant azimuthal wave number [Formula: see text]. Previous linear stability analyses predicted that the amplification characteristics of small-amplitude, unsteady, and convective instabilities within this flow were consistent with the surface pressure fluctuations measured in the experiment. However, their accompanying investigation of global instabilities showed that the separation bubble was weakly unstable at the 10 deg flare angle, with the most unstable global mode corresponding to a stationary disturbance with [Formula: see text] (i.e., well below the measured wave number of [Formula: see text]. Besides characterizing the global instability for selected flare angles, the present numerical simulations quantify the details of the stationary equilibrium state associated with supercritical bifurcation resulting from the nonlinear saturation of the unstable global mode. Although velocity perturbations associated with the saturated global mode are dominated by the fundamental spanwise wavelength associated with the linear global instability, the surface heat flux downstream of the reattachment is dominated by [Formula: see text], in agreement with the experimental measurements.

Published: March 2024

Distal Radius Fractures (DRFs) are the most common type of fracture with a high incidence rate, accounting for 17.5% of all adult fractures. The established clinical workflow for patients with a suspicion of DRF calls for the acquisition of two radiographic X-ray images (radiographs) of the wrist in anteroposterior (AP) and lateral (LAT) views [1]. Radiographic parameters (RPs), which are linear angle and distance measurements derived from the AP and LAT radiographs, have been shown to provide objective support for effective decision making in determining clinical treatment of distal radius fractures (DRFs) [2]. Recently, we showed that providing computed RPs to orthopedic surgeons may improve the consistency of the radiographic judgment and influence their clinical decision for the treatment of DRFs [3]. However, calculating the RPs manually from radiographs requires experience, is time consuming, and is subject to observer variability.This paper presents a novel deep learning automatic method for computing the six anatomical RPs associated with DRFs in AP and LAT forearm radiographs.

The development of 3D printing technology has had a significant impact on the medical field. This technology has made it possible to create custom-made implants that can be flexibly adapted to the bone defects of individual patients. In this study, total hip arthroplasty (THA) using the custom-made implant developed in Japan, was reviewed in patients with severe acetabular bone defects. The accuracy of each implant placement was examined.We retrospectively studied 10 patients who underwent THA with T-REX® (Teijin Nakashima Medical) at our institution between 2020 and 2022. A 3D pelvic model of each patient was created based on preoperative computed tomography (CT) data. The 3D CAD system was used to preoperatively plan the construction of an augmentation and a flange, where necessary. A pelvic model and an implant copy made to the same shape as the custom-made implant were used as a patient-specific guide. Postoperative CT data confirmed implant placement and determined alignment errors.The absolute errors of implant alignment were 3.92 degrees for inclination, 1.81 degrees for anteversion, and 5.48 degrees for rotation. Absolute errors of 1.87 mm in the internal/external direction, 1.55 mm in the anteroposterior direction, and 1.10 mm in the vertical direction were also observed.In conclusion, T-REX® implants can be accurately placed during THA in cases with severe acetabular bone defects. These implants can be expected to provide firm initial fixation by taking advantage of the flexibility in their design, making them a useful treatment option for patients.

One of the goals of total knee arthroplasty (TKA) is to restore of extend the range of motion of the knee joint. A small proportion of patients who are candidates for TKA exhibit fixed flexion contracture (FFC), a condition which prevents the knee from reaching full extension and can be associated with preoperative coronal deformity. In treating FFC, surgeons have two options, either through extensive soft tissue releases or through additional resections of bone on the proximal tibia and distal femur to increase the extension gap. Usually, FFC can be corrected with just soft tissue release, however, sometimes needs to be combined with additional bone resections, especially in cases with varus or valgus coronal deformity. However, additional bone resections beyond 11mm on the femoral side can be associated with knee instability. We therefore asked, is there a relationship between preoperative coronal deformity and intraoperative bone resections required to treat patients with extreme FFC?We analysed 3922 navigated TKA cases undertaken at our institution between March 2007 and October 2022. From this set, we identified 127 patients with extreme fixed flexion contracture (FFC) of greater than 150 and with post-operative FFC less than 50, indicating that the FFC had been resolved. Using simple linear regression and calculating the Pearson correlation coefficients, we related the preoperative coronal deformity to the maximum femoral and tibial resection depths between the medial and lateral sides. We then calculated the statistical significance and coefficient of determination.For the 127 cases, the coefficients of determination were calculated to be 0.19 for the proximal tibia and 0.22 for the distal femur (p &lt; 0.025). The correlation coefficients for the relationship between coronal deformity and femoral or tibial resection depths were 0.47 (p&lt; 0.025) and -0.43 (p&lt; 0.025), respectively.In this study, we determined there was a moderate correlation (indicated as |0.40 – 0.59|) between the tibial and femoral bone resections required to treat extreme FFC in patients with varying degrees of preoperative coronal deformity. In planning to treat extreme FFC, surgeons should pay attention to the preoperative coronal deformity of patients as this will likely be an important factor in determining the required steps in successfully treating the FCC.
Ammonia Accumulation as a Proxy to Determine Cage-change Frequency in Antelope Ground Squirrels (Ammospermophilus leucurus)

Published: March 2024

AbstractDue to a lack of evidence-based standards for cage-change intervals for antelope ground squirrels (AGS, Ammospermophilus leucurus), we evaluated cage ammonia accumulation in our colony of adult, wild-caught AGS and identified factors that influenced ammonia levels. Intracage ammonia was measured daily in singly housed AGS in static caging that contained a running wheel and 1/2, 3/4, 1, or 2 quart (qt) of corncob bedding. Cages were changed when ammonia levels reached greater than 50 ppm, our upper acceptable limit for ammonia based on mouse studies of ammonia aversion and toxicity. We also measured average daily water consumption over 2 wk to examine any correlation between water use and ammonia accumulation. We hypothesized that the desert-dwelling AGS would not reach intracage ammonia levels of greater than 50 ppm in a 2-wk interval at any bedding volume. Our data showed that intracage ammonia was highly variable among individuals and was significantly associated with water consumption and bedding volumes. Seventeen percent of AGS on 1/2 qt of bedding and 18% on 3/4 qt of bedding reached greater than 50 ppm ammonia before 7 d. All AGS on 1 and 2 qt of bedding remained below 50 ppm ammonia for 1 wk. Even when maintained on 2 qt of bedding, not all AGS remained below 50 ppm ammonia for 2 wk. Therefore, we concluded that the most appropriate option was weekly cage change for singly housed AGS on 1 qt of bedding in static caging.

This study finds the equilibrium configuration, vibrational analysis, thermodynamic properties, and electronic properties of formaldehyde and its derivatives, namely acetone, acetyl chloride, and methyl acetate, using First Principles Analysis. It emphasizes the impact of substituents on the carbonyl group and the need for this comprehensive analysis. The computational methods employed in this work are Gaussian DFT), GaussSum and Moltran calculations. For formaldehyde, the optimization step starts from the energy of -114.51282 Hartree and gets optimized in the energy -114.5129634 Hartree. Similarly for Acetone, Acetyl chloride and Methyl acetate, optimization step start from -193.74375 Hartree, -613.26 Hartree, -266.805 Hartree and gets optimized in the energy -193.1744033 Hartree, -613.2941798 Hartree, -266.8358066 Hartree. Infrared (IR) spectroscopy is used to analyze vibrational frequencies. The C-H and C=O vibrations are highlighted, showing characteristic peaks for each compound. Heat capacity at constant volume (Cv), heat capacity at constant pressure (Cp), internal energy (U), enthalpy (H), entropy (S) and Gibb’s free energy (G) with change in temperature sharply increase from 10 K to 50 K and decreases the increase in rate from 50 K to 500 K. In the derivative of Formaldehyde, Methyl Acetate has the highest energy gap (i.e. -7.4222 eV) and Acetyl Chloride has the small energy gap (i.e. 5.6137 eV). The Chemical parameters like ionization potential, electron affinity, chemical hardness, chemical potential, electronegativity, electrophilicity index, and chemical softness have been also calculated. Electrostatic Potential (ESP) Surfaces, Molecular Electrostatic Potential (MEP), and Electron Density (ED) are visualized to understand charge distribution and reactivity regions. DOS spectra illustrate the density of electron states per unit energy.
