Middle East Respiratory Syndrome (MERS), Severe Acute Respiratory Syndrome (SARS), and kinds of influenza can be given as example these diseases. The novel corona virus which is called COVID-19 is the most dangerous problem all around the world in these days.

While the agricultural sector contributes the economic growth, it also induces GHGs and causes environmental degradation. The effect of agriculture activities on environmental degradation receives attention last several years in environmental Kuznets curve (EKC) literature. The aim of this paper is to investigate the effect of agriculture activities (AGRI), energy consumption (EC), foreign direct investment (FDI), and trade openness (TO) on CO in the context of EKC hypothesis for the Next Eleven countries in the period of 1991-2019.

Background: The aim of this study was to determine the factors affecting mortality rate among patients with an electrical burn.
Methods: A total of 115 patients admitted to the emergency department and hospitalized in the Burn Treatment Center or Intensive Care Unit (ICU) due to the electrical burn, were included in the study.
Results: A total of 115 patients (4 female and 111 male) with a mean age of 32.

Background: The aim of the present study was to present characteristic features and risk factors of paint thinner burns in order to raise awareness and help prevent these injuries.
Methods: Records of patients admitted to the burn unit due to paint thinner burns were retrospectively reviewed, and patients with comprehensive data available were included in the study. Total of 48 patients (3 female and 45 male) with mean age of 27.
Burn injuries are associated with the negative effects on the musculoskeletal system and are important causes of severe disabilities. The aim of this study was to evaluate bone mineral density (BMD), bone turnover markers, and 25(OH) vitamin D levels in male patients with sustained at least 1 year postburns involving more than 30% of the TBSA in comparison to a control group and evaluate the relation between the characteristics of scar tissue and BMD and 25(OH) vitamin D levels. The study included 25 male patients who previously sustained burn injuries involving more than 30% of the TBSA and 20 healthy subjects as the control group.

In this work, we analyze the effect of discretization on the accuracy of fluorescence diffuse optical tomography. We model the forward problem by a pair of diffusion equations at the excitation and emission wavelengths and consider a finite element discretization method for the numerical solution of the forward problem.

Our error analysis provides two new error estimates which present a direct relationship between the error in the reconstructed fluorophore concentration and the discretization of the forward and inverse problems. In this paper, based on these error estimates, we develop two new adaptive mesh generation algorithms for the numerical solutions of the forward and inverse problems in FDOT, with the objective of error reduction in the reconstructed optical images due to discretization while keeping the size of the discretized forward and inverse problems within the allowable limits.

In this paper, we propose a hierarchical Bayesian approach to improve spatial resolution and quantitative accuracy by using a priori information provided by a secondary high resolution anatomical imaging modality, such as magnetic resonance (MR) or x-ray. In such a dual imaging approach, while the correlation between optical and anatomical images may be high, it is not perfect.
View Article and Find Full Text PDFDiffuse optical tomography is a typical inverse problem plagued by ill-condition. To overcome this drawback, regularization or constraining techniques are incorporated in the inverse formulation. In this work, we investigate the enhancement in recovering functional parameters by using physiological and spatial a priori constraints.
