Analysis of the problem with chang phase

, 2008
O presente trabalho tem como objetivo o emprego da técnica de elementos de contorno na solução do problema unidimensional de solidificação em coordenadas cartesianas. A técnica de elementos de contorno transforma o problema original, que era a resolução de uma equação diferencial parcial, na resolução de um sistema de equações não lineares, tendo como ...

Quantifying temporal change in biodiversity : challenges and opportunities

, 2012
Growing concern about biodiversity loss underscores the need to quantify and understand temporal change. Here, we review the opportunities presented by biodiversity time series, and address three related issues: (i) recognizing the characteristics of ...

Real‐World Longitudinal Data on the Impact of Hydroxychloroquine Blood Level Monitoring on Lupus Outcomes: Results of a Prospective Longitudinal Cohort Study

Arthritis Care &Research, EarlyView.
Objective Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), but the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to identify clinical factors that predict ...

Estimation of the Thermophysical Properties of the Soil by Inverse Problem, using Experimental Data during Liquid/Vapour Phase Change [PDF]

, 2015
International audienceIn this work, we introduce a numerical strategy to estimate the thermophysical properties of the soil of a saturated porous medium where a phase change problem (liquid/vapour) appears due to intense heating from above.

Finite Element Technique for Phase-Change Heat Conduction Problem

, 2009
Liquid-solid phase transition is accompanied by a latent heat release, both in isothermal and non-isothermal phase transformations. The latent heat and the discontinuous phase change function increase the difficulty of obtaining a solution for the ...

A Return to Normality: A Descriptive Qualitative Interview Study Exploring the Patient Experience of Gout Flare Resolution

Arthritis Care &Research, EarlyView.
Objective Although the definition of a gout flare is well established, the state of gout flare resolution has not yet been defined. This study aimed to explore patients’ experiences and perceptions of gout flare resolution. Methods Semistructured interviews were conducted with 24 people with gout, guided by open‐ended questions exploring their ...

Approximate Solutions of A Phase Change Problem

, 1983
初期條件이 飽和狀態의 固相이고, 한벽면의 온도가 嚴密한 時間의 함수(단조감소, 단조증가, 주기함수)로 주어지며, 다른 벽면은 단열되어 있는 一次元 相變化 問題에 대하여 近似的 解析方法인 Approximate Neumann's Approach, Megerlin's Method, Biot's Variational Method, Perturbation Method 등을 이용하여 해석함으로써 相變化率과 溫度分布등을 求하였으며 각 해석방법間의 結果의 誤差는 ...
