What is an example of a notch in anatomy?

The mandibular notch, also known as the sigmoid notch, is a groove in the ramus of the mandible. It is the gap between the coronoid process anteriorly and the condyloid process posteriorly.

What is notched in biology?

Notch is the receptor in a highly conserved signalling pathway that is crucial in development and implicated in malignant transformation. The basic paradigm of Notch signalling is simple, and involves proteolytic cleavage to release an intracellular fragment (Nicd) that functions to regulate transcription.

What is the notch effect?

What is the notch effect and how does it affect bolts? A notch is basically each change of the cross-section of a component. It may come from drill holes, grooves or cross-sectional variations. Notches result in uneven stress distribution, leading to stress peaks – known as the notch effect.

How many types of notches are there?

TYPES OF NOTCHES, RECTANGULAR AND TRIANGULAR NOTCHES, RECTANGULAR WEIRS. A notch may be defined as an obstruction over which the flow of liquid occurs. As the depth of flow above the base of the notch is related to the discharge, the notch forms a useful measuring device.

What's a top notch girl?

adjective. If you describe someone or something as top-notch, you mean that they are of a very high standard or quality.

What is notch in fatigue?

Summary. Fatigue cracks mostly initiate at sites of stress concentration. Notches and holes decrease the fatigue strength of structures. This phenomenon is called the fatigue notch effect. However, it is difficult to avoid notches and holes, which are in general necessary for the function of structures.

Why are notches used?

Explanation: Notch is a device used for measuring the rate of flow of a liquid through a small channel or a tank. It may be defined as an opening in the side of a tank or a small channel in such a way that the liquid surface in the tank or channel is below the top edge of the opening.

Why is notching important?

Notching offers a wide range of advantages, one of which is the ability to create complex shapes. The workpiece will take the shape of the punch and die tool set used in the process. Therefore, manufacturing companies can create workpieces in complex and unique shapes by using the right punch and die tool set.

What does notch mean in kidney?

Notch is a highly conserved cell-cell communication mechanism that regulates development, tissue homeostasis and repair. Recent studies indicate that Notch plays a key role in kidney development by establishing proximal tubular epithelial cell fate and cell type specification in the renal collecting system.

Is notch a protein?

Notch receptors are modular, single-pass transmembrane proteins that receive signals from transmembrane ligands that are expressed on neighboring cells.

What is the notch in the neck?

The suprasternal notch, also known as the fossa jugularis sternalis, jugular notch, or Plender gap, is a large, visible dip in between the neck in humans, between the clavicles, and above the manubrium of the sternum.

What is a stress notch?

In structural components, a notch causes a stress concentration which can result in the initiation and growth of fatigue cracks. Notches are used in materials characterization to determine fracture mechanics related properties such as fracture toughness and rates of fatigue crack growth.

What is notched strength?

The notch tensile strength (NTS) of a material is the value given by performing a standard tensile strength test on a notched specimen of the material. The ratio between the NTS and the tensile strength is called the notch strength ratio (NSR).

What is notch effects in fatigue and fracture?

The notch effect in fracture is characterised by the fact that the critical gross stress of a notched structure is less that the critical net stress which acts on the remaining ligament area under the notch tip. The notch effect in fracture is sensitive to structure geometry, scale effects and loading mode.
