Electromagnetic flowmeters
The document discusses various methods for measuring blood flow and volume, which are important for understanding physiological processes. It describes electromagnetic flowmeters, ultrasonic flowmeters including Doppler and transit-time types, and indicator dilution methods using dyes or thermal changes. Electromagnetic flowmeters measure flow based on Faraday's law of induction, while ultrasonic flowmeters rely on transit time differences or the Doppler effect from blood cell movement. Indicator dilution involves injecting a substance and measuring its dispersion over time to calculate flow. Together these provide noninvasive or minimally invasive ways to obtain important blood flow information.

Tachometers include the Fullarton and Frahm tachometers, which use cantilever strips with masses to resonate at the frequency of vibration. Quartz, rubidium, and cesium oscillators use the piezoelectric effect of crystals to generate precise frequencies. Quartz oscillators are inexpensive but drift over time, while rubidium oscillators are accurate to 5x10-10 and cesium oscillators are the most precise standard at below 1x10-12 but are also very expensive.
Presentation GROUP TWO.pptx
Group 2 presented on different modes of operating an ultrasound transducer. They explained that a transducer can be operated in shock-excited mode, burst-excited mode, or continuous mode. In shock-excited mode, the transducer is excited by a brief driving voltage impulse, producing impulses within the resonant frequency range. Burst-excited mode involves excitation by 1-2 cycles of alternating voltage, producing pulses of 1-3 selected frequencies. Continuous mode uses repeating cycles of alternating voltage to produce a non-pulsed wave repeating at the resonant frequency indefinitely. The group defined key terms and introduced piezoelectric transducers and their operation under the pulse-echo principle.

Neuronal Communication -EPSP & IPSP
Neurons communicate using both electrical and chemical signals. Sensory stimuli are converted to electrical signals.
Electroencephalogram
An EEG is a procedure that detects abnormalities in your brain waves, or in the electrical activity of your brain.
Brain- Learning Points
The document summarizes the main parts and functions of the human brain. It discusses the forebrain which includes the cerebrum, hypothalamus, and thalamus. The midbrain contains the tectum and tegmentum. The hindbrain is made up of the cerebellum, medulla oblongata, and pons. The cerebrum is the largest part and is divided into four lobes (frontal, parietal, occipital, temporal) which are responsible for functions like reasoning, movement, vision, and memory. The cerebellum coordinates body movements and maintains balance. The brainstem controls basic functions and relays messages between the brain and body. The hypothalamus regulates
Nervous System Anatomy
The nervous system is made up of the central nervous system and the peripheral nervous system. The central nervous system (CNS) is made up of the brain and spinal cord. The brain controls most body functions, including awareness, movements, sensations, thoughts, speech and memory.
Ram manohar lohiya
Dr. Ram Manohar Lohia was an Indian democratic socialist and political activist who opposed capitalism, communism, and the English language. He believed in decentralized governance through village, district, provincial, and central governments each with sovereign powers. Lohia was influenced by German philosophers like Marx and Hegel and advocated for individual freedom and economic security. He criticized Gandhi for his concepts of trusteeship, nonviolence, and spinning wheels. Lohia wanted to establish his own socialist party and engage with Ambedkar on tackling discrimination based on caste, class, gender and more.
Pre-Monsoon - Western Disturbance
Western disturbances originate over the Caspian Sea and Mediterranean Sea as subtropical cyclones south of 20°N, then travel over Iran, Afghanistan, Pakistan, and into the Indian subcontinent including Punjab, Haryana, Delhi, Uttar Pradesh, and sometimes northeastern regions. They bring winter and pre-monsoon rainfall which is important for crops like wheat in northern regions. In the absence of moisture, strong upward air currents carry dust and cause dust storms. Western disturbances typically occur between January and April.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
