Edited at 2025-01-18 20:02:31Rumi: 10 dimensions of spiritual awakening. When you stop looking for yourself, you will find the entire universe because what you are looking for is also looking for you. Anything you do persevere every day can open a door to the depths of your spirit. In silence, I slipped into the secret realm, and I enjoyed everything to observe the magic around me, and didn't make any noise. Why do you like to crawl when you are born with wings? The soul has its own ears and can hear things that the mind cannot understand. Seek inward for the answer to everything, everything in the universe is in you. Lovers do not end up meeting somewhere, and there is no parting in this world. A wound is where light enters your heart.
Chronic heart failure is not just a problem of the speed of heart rate! It is caused by the decrease in myocardial contraction and diastolic function, which leads to insufficient cardiac output, which in turn causes congestion in the pulmonary circulation and congestion in the systemic circulation. From causes, inducement to compensation mechanisms, the pathophysiological processes of heart failure are complex and diverse. By controlling edema, reducing the heart's front and afterload, improving cardiac comfort function, and preventing and treating basic causes, we can effectively respond to this challenge. Only by understanding the mechanisms and clinical manifestations of heart failure and mastering prevention and treatment strategies can we better protect heart health.
Ischemia-reperfusion injury is a phenomenon that cellular function and metabolic disorders and structural damage will worsen after organs or tissues restore blood supply. Its main mechanisms include increased free radical generation, calcium overload, and the role of microvascular and leukocytes. The heart and brain are common damaged organs, manifested as changes in myocardial metabolism and ultrastructural changes, decreased cardiac function, etc. Prevention and control measures include removing free radicals, reducing calcium overload, improving metabolism and controlling reperfusion conditions, such as low sodium, low temperature, low pressure, etc. Understanding these mechanisms can help develop effective treatment options and alleviate ischemic injury.

Electromagnetic induction Lengz's Law
magnetic flux
Meaning: The number of magnetic inductive lines passing through a certain plane, referred to as magnetic flux
formula:
Notice
Has nothing to do with the number of turns
The area with a magnetic field is the effective area
Positive and negative represent entry and exit, positive and negative disappear
Electromagnetic induction phenomenon
Magnetic electricity generation
Who found it?
Faraday
Induction current generation conditions
Closed loop magnetic flux change
How to judge Induction current direction
Lengz's Law
Sensitive
Increased reversal
Φ increases, and the sense B is opposite to the original B to prevent the increase of Φ
Reduce the same
Φ decreases, and the sense B is in the same direction as the original B to prevent Φ decrease
Brief Note
Increase and decrease in the same as the original sense
Right-hand rule
Animal
Stretch your right hand, B is heart-wrenching, thumb V, four fingers are flowing
Tips and tricks
Increase × inverse, decrease × straight; increase point straight, decrease point inverse
Expand application of Lengz's law
Current-current
Increase, repulse and reduce, and absorb
Detailed Spring
Near repulsion and distant suction
Spring lecture
Ampere
Come and refuse to stay
Increase, decrease and expand
Increase, decrease, shrink
