Skin lesions and diagnosis
The document discusses the diagnosis of skin lesions. It notes that correctly recognizing significant lesions can save lives, while failing to recognize normal variations can cause harm. The skin can provide clues to internal conditions - genetic mutations or hormonal imbalances can cause changes both externally and internally. When diagnosing lesions, dermatologists consider what tissue is affected, the primary and secondary changes, the type, shape, arrangement and distribution of lesions, and how they have evolved over time. Taking a thorough history including descriptions, prior treatments, medications, environmental exposures, and physiological changes helps bring order to diagnosis. Experienced clinicians often examine the rash first to make a visual diagnosis before considering the history.

Osteoporosis- a skeletal disorder
Today the most common skeletal disorder we hear is osteoporosis. So I would like to share a little information about it.
Integumentary system
The integumentary system consists of the skin, hair, nails, and exocrine glands. It serves several protective functions including preventing water loss, regulating temperature and metabolism, and providing immune defense. The skin is composed of two main layers - the epidermis and dermis. The epidermis contains melanin which determines skin color and the dermis contains connective tissue. Accessory organs of the skin include nails, hair, and exocrine glands. Common skin disorders include acne, burns, and various types of skin cancer like basal cell carcinoma and melanoma.

Functions and disorders of the Integumentary System
This document discusses the functions and disorders of the integumentary system. It begins by outlining the seven main functions of the skin, which include absorption, excretion, production, protection, regulation, perception, and storage. It then describes the layers of the skin - epidermis, dermis, and subcutaneous layer - and their roles. The document also examines various disorders that can affect the skin, such as acne, burns, dermatitis, eczema, herpes, impetigo, psoriasis, ringworm, scabies, shingles, and skin cancers. It concludes by relating the integumentary system to the body's communication systems.
The Skeletal System
The skeletal system provides structure and movement to the body. It works with muscles as part of the musculoskeletal system. There are different types of bones including long, short, irregular, flat, compact and spongy bones. Joints allow bones to move and come in immovable, slightly movable, and freely movable varieties like hinge, pivot, and ball and socket joints. Ligaments connect bones at joints while cartilage cushions joints and can form cartilage bones in infants.

Excretory System
The document discusses the excretory system and its role in removing waste from the body. It describes the kidneys, ureters, urinary bladder, and urethra as key organs that filter blood, remove waste as urine, and store and expel urine from the body. The kidneys filter blood and regulate fluid and electrolyte balance while the ureters carry urine from the kidneys to the bladder for storage until urination through the urethra.
Structures of the Integumentary System
The document discusses the structures of the integumentary system. It is composed of three main layers: the epidermis, dermis, and subcutaneous layer. The epidermis is the outermost layer made of epithelial cells. The dermis, made of connective tissue, lies below the epidermis and contains structures like collagen, blood vessels, hair follicles and sweat glands. Below the dermis is the subcutaneous layer, which stores adipose tissue. Other structures included are hair, nails, sebaceous glands and sudoriferous glands.

Skeletal And Muscle Ppt
The skeletal system provides structure and support for the body. It includes bones like those in the spine, arms, legs, skull, and rib cage. Joints connect bones and allow movement, such as ball-and-socket joints in the shoulder and hip. Taking care of bones requires adequate calcium, vitamin D, and exercise. Problems can arise from injury, poor nutrition, or conditions like osteoporosis.
The integumentary system
This document summarizes the structure and function of the integumentary system. It begins by defining the integumentary system as the skin and its derivatives (hair, nails, glands). It then describes the three layers of skin - epidermis, dermis and hypodermis - and their roles in protection, sensation, regulation and other functions. Key aspects like hair follicles, sebaceous glands, sweat glands and nails are also summarized. The document provides an overview of the integumentary system with a focus on skin anatomy and physiology.
Common skin diseases
Common skin diseases include:
- Scabies, caused by mites under the skin, which can be treated with sulfur or cleaning the infected environment.
- Ringworm, caused by a fungus and presenting as a red, itchy ring, which can be treated with antifungal creams.
- Eczema, whose cause is unknown but may be triggered by stress or irritants, presenting as inflamed, red, dry, and itchy skin, treated with corticosteroids or antihistamines.
- Psoriasis, cause unknown but involving too-rapid skin cell growth, appearing as thick red plaques covered in silvery scales, treated with steroid creams or phot
Excretory System
The document summarizes the key components and functions of the human excretory system. It describes how the kidneys filter blood and remove waste via specialized structures called nephrons. Nephrons filter blood in the glomerulus and reabsorb nutrients in the tubules, with waste collected and excreted as urine through the ureters, bladder, and urethra. The process involves filtration, reabsorption, and regulation by hormones to maintain water balance as urine is produced and stored before removal from the body.
Muscular system
The muscular system allows for movement through muscles that are connected to the skeleton and controlled by the nervous system. There are three main types of muscles: skeletal muscles that move bones, smooth muscles that control internal organs, and cardiac muscles that form the heart. Muscular dystrophy is a genetic disease characterized by the progressive weakening and loss of skeletal muscles. Some common forms include Duchenne muscular dystrophy which affects boys and leads to wheelchair dependence in the early teens, and facioscapulohumeral muscular dystrophy which initially affects muscles in the face, shoulders, and arms. Limb-girdle muscular dystrophy affects muscles in the hips and shoulders. Myotonic muscular dystrophy affects multiple body systems and causes muscle wasting
Skeletal System Ppt
The skeletal system is composed of 206 bones that provide structure, protect organs, allow movement, and produce blood cells. Bones are living tissues made of cells and composed of minerals and collagen. The skeletal system includes bones in the hands, face, and longest bone being the femur, with the smallest being the stirrup bone in the ear. Joints connect bones to enable the body's 230 movable joints, and giraffes have the same number of neck bones as humans.

Human physiology, integumentary systems
REGION OF THE INTEGUMENT
Integere is defined as to cover, which bring the meaning of integumentary. This system covers the body part that include human skin, nail, and hair. These integument works as defenses against foreign microbes, prevent microbial penetration wherever body tissues are exposed to the external environment. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature. In order to do these things, the integumentary system works with all the other systems of body, each of has a role to play in maintaining the internal conditions that a human body needs to function properly.
ACCESSORY STRUCTURE IN THE INTEGUMENT
The most obvious external part that cover the human body is skin which has many
functions, most of which are involved in protecting and regulating body internal functions in a variety of ways:
Protects the body internal living tissues and organs
Protects against invasion by infectious organisms
Protects the body from dehydration
Protects the body against abrupt changes in temperature
Helps dispose of waste materials
Acts as a receptor for touch, pressure, pain, heat, and cold
Stores water and fat
The skin is not only a mechanical barrier between the external environment and the
underlying tissues but is dynamically involved in defense mechanisms and other
important functions as well.

The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Abstract:
In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.Micronuclei test.M.sc.zoology.fisheries.
Current Ms word generated power point presentation covers major details about the micronuclei test. It's significance and assays to conduct it. It is used to detect the micronuclei formation inside the cells of nearly every multicellular organism. It's formation takes place during chromosomal sepration at metaphase.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.
