概括

鱼的皮肤机制因游泳风格而异,轴波浪者表现出最强硬的皮肤. 雄性刺鱼的皮肤也比雌性皮肤更坚固,这突出了软骨鱼类的适应性.

科学领域:

*比较的生物力学.
* 功能形态学功能形态学
* 鱼类的运动方式

背景情况:

* Batoids,dorsoventrally压缩的软骨鱼,在移动时面临独特的机械挑战.
* 之前的研究表明,单一的巴托类物种具有异性皮肤特性.
* 宝类物种之间不同的游泳策略表明皮肤机制的潜在变化.

研究的目的:

* 为了研究不同的运动运动策略如何影响 batoid 皮肤的机械性质.
* 为了比较六种代表不同游泳风格的鱼类物种的皮肤机制.
*根据性别和身体区域来评估皮肤机械行为的变化.

主要方法:

* 准静态单轴张力测试在六种鱼物种的背部,腹部和复合性皮肤样本上进行.
* 机械行为 (应变,强度,刚性,性) 在不同的功能群体,身体区域,性别和压力轴上得到量化.
* 根据游泳风格分类物种:轴波浪,胸盘波浪,半振荡和振荡.

主要成果:

*皮肤伸展性在波浪者中最高;轴波浪者表现出最强和最硬的皮肤.
* 在游泳风格和身体区域之间观察到机械性质的显著差异.
* 在大西洋鱼中,与雌性相比,雄性表现出明显更强壮,更坚固的皮肤.

结论:

* 机动运动策略是塑造形动物皮肤机械特性的一个关键因素.
*这些发现为了解不同物种和游泳风格的鱼皮肤机制提供了一个框架.
*结果可以为仿生材料的设计提供信息,这些材料的灵感来源于 batoid 皮肤的适应性.

Membrane Fluidity

Membrane Fluidity

Cell membranes are composed of phospholipids, proteins, and carbohydrates loosely attached to one another through chemical interactions. Molecules are generally able to move about in the plane of the membrane, giving the membrane its flexible nature called fluidity. Two other features of the membrane contribute to membrane fluidity: the chemical structure of the phospholipids and the presence of cholesterol in the membrane.

Buoyancy and Stability for Submerged and Floating Bodies

Buoyancy and Stability for Submerged and Floating Bodies

In fluid mechanics, buoyancy and stability are key concepts for understanding the behavior of submerged and floating bodies. When a stationary body is fully or partially submerged in a fluid, the fluid exerts a force on the body known as the buoyant force. This force acts vertically upward through a point called the center of buoyancy, which is the center of the displaced fluid volume. According to Archimedes' principle, the magnitude of the buoyant force is equal to the weight of the fluid...

Body Water Content and Fluid Compartments

Body Water Content and Fluid Compartments

Life's biochemical processes occur within aqueous solutions. Solutes are substances that are dissolved within these solutions. The human body contains a variety of solutes, which can differ across various body parts. These can encompass proteins—such as those responsible for clotting and carbohydrate transport—as well as electrolytes. In medicine, an electrolyte is often described as a mineral ion derived from a salt possessing an electric charge. Examples include sodium ions...
