This study develops and analyzes linear and nonlinear state space models for estimating the elemental composition of scrap steel used in steelmaking, with applications to Electric Arc Furnace (EAF) and Basic Oxygen Furnace (BOF) processes. The models...
In this manuscript we present an in vitro model based on agarose gel that can be used to simulate a dirty, oily, bloody, and morphologically complex surface of, for example, an open wound. We show this models effectiveness in simulating depth of pene...
Jan 31, 2026 · Angina pectoris, pain or discomfort in the chest, usually caused by the inability of diseased coronary arteries to deliver sufficient oxygen-laden blood to the heart muscle.

The meaning of ANGINA PECTORIS is a disease marked by brief sudden attacks of chest pain or discomfort caused by deficient oxygenation of the heart muscles usually due to impaired blood flow …
Jun 30, 2023 · Angina, also known as angina pectoris, is chest pain or discomfort that occurs when part of your heart muscle does not get enough oxygen-rich blood. It is a common symptom of coronary …
Nov 14, 2025 · Angina pectoris, or angina for short, is chest discomfort that occurs when the heart doesn't get enough oxygen. It can feel like pressure, squeezing, or pain in the chest. Angina can be …
Angina is chest pain or discomfort that occurs when some part of your heart does not get enough blood and oxygen. Angina is a symptom of coronary artery disease.
In the paper, the initial-boundary value problems to a semilinear integro-differential equation with multi-term fractional Caputo derivatives are analyzed. A particular case of this equation models oxygen diffusion through capillaries. Under proper a...
A study of interaction of neutron rich oxygen isotopes $^{17,18}$O with light targets has been undertaken in order to determine the optical potentials needed for the transfer reaction $^{13}$C($^{17}$O,$^{18}$O)$^{12}$C. Optical potentials in both in...
Da dieser organische Kohlenstoff zuvor schon durch eine oxygene Photosynthese fixiert wurde, erfolgt bei der Photosynthese auf der Grundlage bakteriogener Schwefelverbindungen keine Nettozunahme …
Now for the tricky part. When chemists report an elemental analysis and it adds up to less than 100%, the difference is generally attributed to oxygen. Our analytical methods, constrained by working in an …
I am looking to buy a generator for the occasional power loss as my mother in law is on oxygen and a few other small medical devices. In the summer I might need it for a fridge or two but that is the ...
the valence of hydrogen is 1, of oxygen is 2, of nitrogen is 3, and of carbon is 4. Valence is not to be confused with the related concepts of the coordination
Medically, shock is defined as a condition where the tissues in the body don't receive enough oxygen and nutrients to allow the cells to function. This ultimately leads to cellular death, progressing to …
Nov 2, 2023 · Lack of blood flow means the cells and organs do not get enough oxygen and nutrients to function properly. Many organs can be damaged as a result. Shock requires immediate treatment …
Jun 25, 2025 · Shock makes your organ systems shut down due to a lack of blood flow and oxygen. The goal of shock first aid is to stabilize a person as much as possible and buy time until they can get …
The details of ignition of Type Ia supernovae remain fuzzy, despite the importance of this input for any large-scale model of the final explosion. Here, we begin a process of understanding the ignition of these hotspots by examining the burning of...
