まとめ
スキンタイトニングのための高周波(RF)治療では、個々の脂肪厚に基づいてエネルギーレベルを調整する必要があります。より厚い脂肪層は、効果的な皮膚修復および組織再生のために、より高いエネルギーまたはより長い治療時間を必要とします。

- 生物医学工学
- 皮膚科学
- 医用物理学
背景:
- モノポーラ高周波(RF)は、スキンタイトニングおよび組織修復のために熱を発生させます。
- 皮下の脂肪厚の変動は、RF浸透および熱閾値の一貫性の低下につながります。
- 個別化された治療結果は、不均一な熱分布によって損なわれます。
研究 の 目的:
- 脂肪厚が異なる組織におけるRF誘発温度分布を解析すること。

- 4つの脂肪厚(2、4、6、8 mm)全体でRF曝露(6.78 MHz、120 W)をシミュレートしました。
- in vitroの豚組織実験を使用して、電磁熱結合効果を検証しました。
主要な成果:
- FEAシミュレーションは実験的に検証され、脂肪厚全体で一貫した熱的傾向を示しました。
- 治療後の組織内温度は、69°C(脂肪厚2 mm)から45°C(脂肪厚8 mm)の範囲でした。
- すべてのシミュレーション温度は、安全な表皮限界内に留まりました。
結論:
- RF治療エネルギーパラメータは、個々のアディポサイト組織の厚さに合わせて調整する必要があります。
- より厚い皮下脂肪は、最適な結果を得るために、より高いエネルギーまたはより長い治療期間を必要とします。

NMR Spectrometers: Radiofrequency Pulses and Pulse Sequences
1.7K
A pulse is a short burst of radio waves distributed over a range of frequencies that simultaneously excites all the nuclei in the sample. Upon passing a radio frequency pulse along the x-axis, the nuclei absorb energy corresponding to their Larmor frequencies and achieve resonance. This shifts the net magnetization vector from the z-axis toward the transverse plane. This angle of rotation of the magnetization vector, or the flip angle, is proportional to the duration and intensity of the pulse.

Design Example: Deciding Thickness of Lubricating Fluid in a Shaft
332
Effective lubrication between a rotating shaft and its bearing housing is essential in rotating machinery to minimize friction, wear, and energy loss. With carefully controlled thickness and viscosity, the lubricant layer prevents metal-to-metal contact, ensuring smooth operation.
To calculate the required thickness of the lubricant layer, the tangential velocity at the shaft's surface must first be determined. This velocity is calculated by converting the rotational speed to angular velocity...

Body Temperature
1.4K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

Body Temperature
4.1K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

Effects of Temperature on Free Energy
28.0K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

Fats as Energy Storage Molecules
26.9K
Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl-CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis...
