Space debris occupying low Earth orbits poses critical threats for future missions, and the popularity of small satellite constellations CubeSats is likely to significantly augment traffic in such valuable orbits. A CubeSat without any deorbiting mechanism could remain these hundreds years. The aerodynamic deorbit experiment (ADE) CubeSat, developed by researchers at Purdue University, relies on a dragsail provide accelerated passive post-mission. good estimation aerothermal load reentry...
High-speed flow problems of practical interest require a solution nonequilibrium aerothermochemistry to accurately predict important phenomena, including surface heat transfer and stresses. The complex coupling effects on the aerothermal load remains challenging aspect hypersonic modeling. As majority these are in continuum regime, computational fluid dynamics (CFD) is useful tool for modeling flows. However, there limited number CFD solvers with capabilities that highly scalable parallel...
The rate of dissociation behind a strong shock in thermochemical nonequilibrium depends on the vibrational excitation molecules, hence rates become function translational-rotational and temperatures. Macheret–Fridman (MF) model provides analytical expressions for assuming collision molecules to be impulsive limit. However, original form was limited homonuclear molecules. In this work, we present general classical by considering heteronuclear molecule macroscopic applicable modeling...
Studies have shown that salt concentrations are increasing in waterbodies such as lakes, rivers, wetlands, and streams areas where deicers commonly applied for winter road maintenance, resulting degraded water quality. As the concentration varies spatially temporally based on environmental hydrological characteristics, we monitored high resolution (15 min) a relatively long period (winter spring season) at different sites (i.e., stream, urban-stream, roadside drain, parking-lot drain) using...
A fast Fourier spectral method is an efficient technique of solving the Boltzmann collision operator. The combined with a discontinuous Galerkin spatial discretization offers highly accurate and high-order solution full equation. In this paper, verification (DGFS) solver presented for classical rare fied flow problems, by comparisons standard solvers; such as direct simulation Monte Carloand Navier-Stokes-Fourier continuum-based solvers. Anormal shock, one-dimensional Couette,...
Methemoglobin (MetHb) is a form of hemoglobin in which iron Hb an oxidized (ferric) instead ferrous, making it difficult to bind with oxygen. Usually, MetHb present small quantities (<1%) humans, but once increases beyond 3%, the condition known as methemoglobinemia. It can be further classified into hereditary and acquired. Hereditary forms are rare cause hypoxia cyanosis. Only few cases have been reported worldwide. Here, we case 33-year-old female congenital methemoglobinemia who...
The overuse of laboratory testing is common in the intensive care unit (ICU) which leads to an increased cost and potential for harm patient. There no evidence that obtaining daily tests helps reduce mortality or morbidity critical patients. We conduced a retrospective study where chart review was performed assess frequency unnecessary followed by quality improvement initiative. With our we were successful at reducing inappropriate improving appropriate through study.

Three different hypersonic attributes; shock standoff distance, vibrational temperature behind a strong shock, and surface heatflux pressure distribution were investigated for Park, Kuznetsov, Macheret-Fridman models. The features discussed based on various characteristics represented...
Improving the value of care with reduced cost without compromising quality is utmost important in modern era medical practice. An attempt was made nursing facility to observe an outcome a plan implement much larger scale future. In 7-month period this ambi- directional study, focus on minimizing unnecessary daily laboratory orders and reduction adverse effect length stay hospitalization from facility.
