- 放射学 放射学是一门学科.
- 法医人类学 法医人类学
背景情况:
- 内部声学介质 (IAM) 是骨中的一个关键的解剖结构.
- 了解其形态特征对于临床和法医应用至关重要.
- 之前的研究集中在尺寸上,对空间参数 (如方向角,方向角等) 的关注较少.
研究的目的:
- 用高分辨率计算机断层扫描 (CT) 来评估IAM的形态特征.
- 为了确定IAM尺寸和角度的性别和年龄相关差异.
- 评估IAM方向和横向角度 (LA) 的临床和法医相关性.
主要方法:
- 追溯分析了162个骨CT扫描 (94名女性,68名男性;年龄为1-77岁).
- 测量包括IAM入口直径,长度,中间直径,侧面角 (LA) 和方向角.
- 根据性别和年龄的统计比较,使用t测试和曼-惠特尼U测试.
主要成果:
- IAM的长度和直径没有显著的性别或年龄差异 (p > 0.05).
- 侧面角 (LA) 和方向角显示出与性别相关的显著变化 (p < 0.05).

Internal Energy
36.9K
The total of all possible kinds of energy present in a substance is called the internal energy (U), sometimes symbolized as E. Suppose a system with initial internal energy, Uinitial, undergoes a change in energy (transfer of work or heat), and the final internal energy of the system is Ufinal. Change in internal energy equals the difference between Ufinal and Uinitial.

Sex-linked Disorders
109.3K
Like autosomes, sex chromosomes contain a variety of genes necessary for normal body function. When a mutation in one of these genes results in biological deficits, the disorder is considered sex-linked.

Internal Receptors
74.7K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Contact Angle
25.7K
When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Location and Orientation of the Heart
10.9K
The human heart, despite its modest size and weight, is an organ of remarkable strength and endurance. Roughly the size of a fist, the heart weighs between 250 and 350 grams and is nestled within the mediastinum, the medial cavity of the thorax. It extends obliquely for about 12 to 14 cm, resting on the superior surface of the diaphragm. The heart is positioned anterior to the vertebral column and posterior to the sternum, with two-thirds of its mass lying to the left of the midsternal line.

Electric Potential and Potential Difference
5.8K
Suppose a positive test charge moves away from a positive static charge, then the Coulomb force does positive work, and its electric potential energy decreases. The potential energy per unit charge is defined as the electric potential. The electric potential is independent of the test charge.
When a test charge moves from the initial to the final position, the electric potential difference between those positions is defined as the ratio of the change in the potential energy to the charge on the...
