Published: August 2021

Introduction: Pivotal component of medico-legal investigations is the determination of time since death, or (minimum) postmortem interval, (min) PMI. Forensic entomology can provide reliable estimates of (min) PMI using carrion insect species. Carrion insect arrival and departure occurs in predictable and sequential waves, however, successions may vary depending on geographical location and environmental conditions. Hence, it is crucial to refer to insect succession data of the same region where the death scene occurs. A current gap in forensic entomology research is on carrion-breeding species and succession on decomposition remains/carrions on small islands. Rottnest Island is located off the south-west coast of Perth. The aim of this study was to establish baseline data of carrion insect fauna present on this island, and to provide entomological evidence that may aid in any future investigations on the island. Methods: A list of the insect taxa associated with two decomposing swine hindquarters during the summer season was compiled over a 15-day study period and compared with published mainland data obtained during the same period of the year. Results: Ten insect taxa representing four families were collected and identified in association with the decomposing carrion. The first wave of colonising Diptera species included Calliphoridae species and Sarcophagidae species. The second wave of Diptera comprised Muscidae species, in addition to beetles. Furthermore, ants and spiders were noted throughout the trial. Conclusions: Comparing the results on Rottnest Island with currently available data from mainland WA, showed that the composition of insect speciesand the patterns of succession were similar.

Abstract

OBJECTIVE
To compare serum concentrations of histones and inflammatory markers in dogs with acute pancreatitis and healthy control dogs, investigate associations of these variables with coagulation test results and survival (vs nonsurvival) to hospital discharge, and examine the prognostic utility of clinical findings and routine laboratory and coagulation tests in affected dogs.

ANIMALS
36 dogs.

PROCEDURES
Dogs with findings consistent with acute pancreatitis (n = 29) and healthy control dogs (7) were enrolled in a prospective, observational study. Serum concentrations of histones, interleukin (IL)-6, and tumor-necrosis factor-α were assessed for all dogs. Clinical (including ultrasonographic) findings, relevant history, routine laboratory and coagulation test results, and outcomes were recorded for dogs with pancreatitis. Variables were assessed to determine an association with outcome for affected dogs and hospitalization time for survivors; histone concentrations and markers of inflammation were compared among survivors, nonsurvivors, and controls. Correlation between quantitative variables was investigated.

RESULTS
Serum histone and IL-6 concentrations did not differentiate survivors (n = 23) from nonsurvivors (6); IL-6 concentrations in affected dogs were correlated with 1,2-o-dilauryl-rac-glycero glutaric acid-(6′-methylresorufin) ester lipase activity (rS = 0.436) and hospitalization time (rS = 0.528). Pancreatitis-associated peritoneal fluid, obtundation, and jaundice were more common, and serum bilirubin concentration, serum alanine aminotransferase and aspartate aminotransferase activities, and prothrombin and activated partial thromboplastin times were greater in nonsurvivors than in survivors. Thromboelastometric changes consistent with hypercoagulability were detected in survivors; hypocoagulability was detected in 2 nonsurvivors.

CONCLUSIONS AND CLINICAL RELEVANCE
Serum histone concentrations were not associated with presence of acute pancreatitis or outcome for affected dogs. Further research is needed to investigate the clinical and therapeutic implications of hypocoagulability, hepatocellular injury, and pancreatitis-associated peritoneal fluid in affected dogs.

Objetivo: Avaliar os efeitos da prática de exercício físico de diferentes tipos e intensidades sobre a estimulação do sistema imunológico nos portadores do HIV, bem como os benefícios para a saúde e bem-estar dos indivíduos imunossuprimidos. Revisão bibliográfica: O HIV possui uma alta afinidade pelas células do sistema imunológico, em particular os linfócitos TCD4+, proporcionando uma diminuição na quantidade e qualidade desse complexo. Assim, além dos tratamentos medicamentosos, há também recomendações da prática de exercício físico de forma regular, que auxiliam na estimulação do sistema imunológico, bem como contribuem no controle dos efeitos adversos acarretados pela terapia antirretroviral, sem gerar sequelas no sistema imune, melhorando as medidas antropométricas e funcionais do paciente. Com isso, a atividade física deve ser indicada a afim de favorecer tanto à reconstituição do sistema imunológico, quanto uma melhora na saúde mental do indivíduo. Considerações finais: Este constructo é de fundamental importância, pois irá prover embasamento teórico-metodológico para mais pesquisas sobre a relação da atividade física e a melhora da qualidade de vida dos pacientes portadores do HIV.

Существуют два основных подхода решения задачи тепломассопереноса при численном моделировании промерзания грунтов: 1) решение методом конечных разностей с учетом граничных условий (границей, например, является фронт промерзания); 2) решение методом конечных элементов без учета границ модели. Оба подхода имеют существенные недостатки, что оставляет проблему решения задачи для численной модели промерзания грунтов острой и актуальной. В данной работе представлена физическая постановка промерзания, которая позволяет создать численную модель, базирующуюся на решении методом конечных элементов, но при этом отражающую ход фронта промерзания - то есть модель, в которой объединены оба подхода к решению задачи промерзания грунтов. Для подтверждения корректности модели был проделан ряд экспериментов по физическому моделированию промерзания модельного грунта и выполнен сравнительный анализ полученных экспериментальных данных и результатов расчетов на базе представленной численной модели с такими же граничными условиями, как в экспериментах.
There are two basic approaches to solving the problem of heat and mass transfer in the numerical modeling of soil freezing: 1) using the finite difference method taking into account boundary conditions (the boundary, for example, is the freezing front); 2) using the finite element method without consideration of model boundaries. Both approaches have significant drawbacks, which leaves the issue of solving the problem for the numerical model of soil freezing acute and up-to-date. This article provides the physical setting of freezing that allows us to create a numerical model based on the solution by the finite element method, but at the same time reflecting the route of the freezing front, i.e. the model that combines both approaches to solving the problem of soil freezing. In order to confirm the correctness of the model, a number of experiments on physical modeling of model soil freezing have been performed, and a comparative analysis of the experimental data obtained and the calculation results based on the provided numerical model with the same boundary conditions as in the experiments was performed.

Совершенствование технологий строительства подземных трубопроводов в условиях многолетнемерзлых грунтов, предусматривающее минимизацию теплового воздействия трубопровода на грунт во время эксплуатации, является актуальной научно-технической задачей. Авторами разработан способ прокладки подземного трубопровода, снижающий до минимума его тепловое воздействие на вмещающий мерзлый грунт и позволяющий в процессе дальнейшей эксплуатации поддерживать температуру перекачиваемой нефти без дополнительного подогрева. Конструктивной схемой предусмотрена укладка трубопровода в изолированную траншею с использованием торфа в качестве грунта-изоляции. В рамках исследования разработана модель прокладки трубопровода (в программном комплексе SolidWorks), произведены расчеты его напряженно-деформированного состояния (в программном комплексе ANSYS) и теплового воздействия на мерзлый грунт (в программном комплексе FROST 3D Universal). Установлено, что напряжения и перемещения, возникающие во время эксплуатации трубопровода, уложенного по предложенной конструктивной схеме, находятся в диапазоне допустимых значений, а его тепловое воздействие вызывает незначительное протаивание грунта и минимальные изменения температуры перекачки нефти.
The improvement of technologies of underground pipeline construction in conditions of permafrost soils, providing for the minimization of the thermal effect of the pipeline on the soil during operation is an urgent scientific and technical task. The authors have developed a method for laying an underground pipeline that minimizes its thermal effect on the enclosing frozen soil and allows maintaining the temperature of the pumped oil during further operation without additional heating. The structural layout provides for laying the pipeline in an isolated trench using peat as insulation soil. As part of the study, a pipeline-laying model was developed (using the SolidWorks software package), calculations of its stress-strain state (in the ANSYS software package) and thermal effect on frozen soil (in the FROST 3D Universal software package) were performed. It has been determined that the stresses and displacements arising during the operation of the pipeline laid in accordance with the proposed structural layout are in the range of allowable values, and its thermal effect causes insignificant soil thawing and minimal changes in the oil pumping temperature.
