14 Skull

Bones of the skull: the neurocranium (the portion of the skull that surrounds and protects the brain) or the viscerocranium (ie, the skeleton of the face). Bones of the neurocrani-um: Frontal, Parietal, Temporal, Occipital, Ethmoid, Sphenoid.

Bones of the viscerocranium (surface): Maxilla, Nasal, Zy-gomatic, Mandible. Bones of the viscerocranium (deep): Ethmoid, Sphenoid, Vomer, Lacrimal, Palatine, Inferior nasal concha. Articulations: Most skull bones meet at immovable joints called sutures. The coronal suture is between the frontal and the parietal bones. The sagittal suture is between two parietal bones. The lambdoid suture is between the parietal and the occipital bones. The bregma is the point at which the coronal suture intersects the sagittal suture.

The lambda is the point at which the sagittal suture intersects the lambdoid suture. The pterion is the point on the lateral aspect of the skull where the greater wing of the sphenoid, parietal, frontal, and temporal converge bones. The temporomandibular joint is between the mandibular fossa of the temporal bone and the condylar process of the mandible.

The parotid gland is the largest of the salivary glands. Structures found within the substance of this gland include the following: Motor branches of the facial nerve. CN VII enters the parotid gland after emerging from the stylomastoid foramen at the base of the skull. Superficial temporal artery and vein. The artery is a terminal branch of the external carotid artery.

Retromandibular vein, which is formed from the maxillary and superficial temporal veins.

Great auricular nerve, which is a cutaneous branch of the cervical plexus. Auriculotemporal nerve, which is a sensory branch of V3. It supplies the TMJ and conveys postganglionic parasympathetic fibers from the otic ganglion to the parotid gland. Parotid (Stensen's) duct, which enters the oral cavity at the level of the maxillary second molar. The facial artery is a branch of the external carotid artery in the neck. It terminates as the angular artery near the bridge of the nose.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Temperature sensor TMP107 22.11.2016

The new TMP107 temperature sensor supports up to 32 devices in series. A chain of TMP107 sensors is connected to the microcontroller via one single-wire UART interface.

Each sensor has a unique 5-bit address stored in electrically erasable programmable memory (EEPROM). The address is assigned during the auto assignment operation and is based on the position of each sensor in the chain. The transmission distance of the UART bus can be up to 300 meters. Data is transmitted between sensors using the proprietary SMAART Wire protocol.

The TMP107 provides maximum flexibility in use, allowing you to choose between low power consumption (e.g. when running on batteries) and high refresh rates for real-time applications.

The warning function of the TMP107 is implemented with two registers for storing programmable values for low and high temperatures. After each measurement, the temperature is compared with the values from these registers. When the specified range is exceeded, the sensor sends a corresponding signal, which can be processed by the microcontroller or displayed on the alarm warning LED.

The TMP107 is capable of reading temperature with a resolution of 0,015625°C and an accuracy of +-0,4°C in the range from -20°C to +70°C. This sensor is ideal for replacing NTC and PTC thermistors in applications requiring high measurement accuracy, such as industrial, medical, environmental, and grain storage temperature control systems.

The TMP107 is housed in a SOIC-8 package and is designed for use in a temperature range of -55°C to +125°C.

Features:

High accuracy:
+-0,4°C (max.) at -20°C to +70°C;
+-0,55°C (max.) at -40°C to +100°C;
+-0,7°C (max.) at -55°C to +125°C;
High resolution: 14 bits (0,015625°C);
UART-compatible wired SMAART interface;
Support up to 32 serial devices;
EEPROM for unique addressing, programmable values, general purpose data storage;
Continuous operation and shutdown mode to save energy;
Single conversion mode for energy saving;
Programmable warnings;
Temperature range: -55°C to +125°C;
Voltage range: 1,7 to 5,5V;
Chassis: SOIC-8.

Applications:

Refrigerators and refrigerating chambers;
Distributed temperature measurements;
Thermal protection of power supplies and batteries;
Servers and telecommunication systems;
Building automation;
Agricultural machinery;
Medical instruments;
Industrial systems.
