The axial skeleton provides support and protection for the brain, spinal cord, and organs. It consists of the skull, vertebral column, and thoracic cage. The appendicular skeleton supports the limbs and consists of the pectoral and pelvic girdles. The pectoral girdle attaches the upper limbs, while the pelvic girdle attaches the lower limbs and allows for locomotion. There are five types of bones: flat, long, short, irregular, and sesamoid. Flat bones provide protection, long bones support weight and facilitate movement, and short bones provide stability at joints.

It provides details on the subtalar joint, midfoot, forefoot, hindfoot, movements of the ankle, arches including the medial longitudinal arch, lateral longitudinal arch, and transverse arch, and the windlass mechanism.
Bones of the pelvic girdle
The document describes the anatomy and movement of the pelvis and hip joint. It discusses the bones that make up the pelvis, including the ilium, ischium, pubis and sacrum. It then describes the major ligaments and joints of the pelvis and hip, including the sacroiliac, pubic symphysis and hip joints. It outlines the movements that occur at the pelvis and hip, such as flexion, extension, abduction and rotation. Key muscles that act on the pelvis and hip like the psoas major, iliacus and gluteus maximus are also identified.
Ankle anatomy
The tibia is the largest bone in the lower leg and bears weight. The fibula is smaller and non-weight bearing but forms part of the ankle joint. The talus bone transmits forces from the heel to the lower leg and allows ankle movement. The talocrural joint is formed by the tibia, fibula, and talus, allowing hinge-like up and down motion of the foot. The subtalar joint connects the talus to the heel bone and allows side to side motion. Ligaments including the deltoid on the inside of the ankle provide stability.
Kinesiology Of Ankle And Foot
The document discusses the anatomy and functions of the ankle and foot. It describes the bones, joints, ligaments, and movements involved in the ankle, subtalar, transverse tarsal, tarsometatarsal, metatarsophalangeal, and interphalangeal joints. Additionally, it covers the plantar arches and muscles responsible for plantarflexion, dorsiflexion, eversion, inversion, extension, and flexion of the toes and ankle.
The patella
The patella is a triangular bone located at the front of the knee joint. It protects the knee joint and enhances the leverage of the quadriceps muscle. The patella can dislocate laterally due to forces from the quadriceps. It can also fracture from direct impact or sudden quadriceps contraction. Patellar injuries are common in sports involving sudden twisting or impact to the knee.
Hip joint anatomy
The hip joint is a ball-and-socket joint between the femur and acetabulum. It is made up of bones, cartilage, ligaments, synovial membrane, muscles and nerves. The acetabulum forms the socket of the joint and is reinforced by the acetabular labrum. The femoral head forms the ball and articulates with the acetabulum. Strong ligaments including the iliofemoral, ischiofemoral and pubofemoral ligaments reinforce the joint capsule. The hip joint is supplied by branches of the femoral, sciatic and obturator nerves and has an extensive blood supply. Bursae around the hip joint help with movement.
Arches of foot
The human foot has two basic functions: supporting body weight and propelling the body through locomotion. It is designed with elastic longitudinal and transverse arches that act as shock absorbers. The arches are maintained through bone shape, ligaments, tendons, and muscle slings that act as tie beams and suspension cables to prevent arch collapse under weight. Common foot deformities include talipes (clubfoot), pes planus (flat foot), pes cavus (high arch), hallux valgus (bunion), and hammertoe.
anatomy of pelvic hip
The pelvis is a bony ring formed by the fusion of three bones - the ilium, ischium, and pubis. It supports the spine and forms sockets called acetabula that connect to the femoral heads. The sacrum fuses five vertebrae into a triangular bone and connects the pelvis to the spine. The hip joint is a ball and socket joint that connects the femur to the acetabulum, allowing movement and bearing weight. It is supported by muscles, tendons, ligaments, and a protective labrum and joint capsule that surround it.

The document discusses the appendicular skeleton, which includes the bones of the upper and lower limbs attached to the axial skeleton. The upper appendage includes the pectoral girdle and upper limbs, while the lower appendage includes the pelvic girdle and lower limbs. The lower limb bones must support the entire weight of the body and are the largest and heaviest. Each lower limb contains 31 bones, including the pelvic girdle, femur, tibia, fibula, tarsals, metatarsals, and phalanges. The document provides detailed descriptions of each bone and joint of the lower limb.
Anthropology ppt 1.pdf
Forensic anthropology involves the identification of human remains for legal purposes. It specializes in determining factors like age, sex, ethnicity from skeletal remains to help with identification of murder victims. Some key cases discussed include analyzing the remains of famous figures like Yasser Arafat and Zachary Taylor to determine cause of death. The document also provides information on the structure and types of bones in the human skeletal system, including long bones, flat bones, short bones, and irregular bones. It describes the axial skeleton which includes the skull, vertebrae, ribs, and thoracic cage, as well as the appendicular skeleton including the shoulder girdle, upper and lower limbs.
Skeletal System
The skeletal system consists of 206 bones that are divided into the axial skeleton (skull, vertebral column, ribs, sternum) and appendicular skeleton (limbs and their attaching girdles). Bones provide structure, protection, movement, mineral storage, blood cell formation, and are living tissues that undergo remodeling. The skeletal system includes various bone cell types and bone is composed of inorganic minerals and organic matrix. Common diseases include osteoporosis, rickets, osteomalacia, and Paget's disease.

The skeletal system consists of 206 bones in the human body that provide structure, protect organs, allow movement, and store minerals. The skeleton is divided into the axial skeleton which includes the skull, vertebral column, and rib cage, and the appendicular skeleton which includes the pectoral and pelvic girdles and upper and lower limbs. Bones are living tissues that grow and change over time. Common diseases that affect the bones include arthritis, osteoporosis, tendonitis, and fractures.
Chapter 7&8
There are 206 bones in the human body grouped into the axial skeleton and appendicular skeleton. The axial skeleton includes 80 bones that make up the skull, vertebral column, ribs, and sternum. It forms the central core and foundation of the body. The appendicular skeleton includes 126 bones arranged in the upper and lower limbs, including their attaching girdles, forming the shoulders, arms, legs and allowing for movement.
Appendicular skeleton
The appendicular skeleton consists of the pectoral girdle, which attaches the upper limbs to the trunk, and the pelvic girdle, which attaches the lower limbs. The pectoral girdle includes the clavicles and scapulae. It provides attachment points for muscles that move the arms but is lightweight and allows flexibility. The pelvic girdle fuses the paired hip bones and attaches to the sacrum, forming the basin-like bony pelvis. It supports the internal organs and in females is adapted for childbirth with a wider, shallower shape. Both the upper and lower limbs share the same basic structural plan but differ in function, with the lower
Skeletal system
The skeletal system is made up of 206 bones and cartilage in adults and provides structure, protection, movement, and blood cell production. Bones are living tissues composed of minerals, water, and cells. The skeletal system includes the skull, vertebrae that make up the spine, ribs, pelvis, and bones in the arms, legs, hands, and feet. Bones are connected by joints that allow movement and are protected by cartilage. It is important to take care of bones through safety precautions, exercise, and nutrition like drinking milk.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

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.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
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.

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 skeletal system
- 2. Axial Skeleton – Brief explanation • Provides support and protection for the brain, spinal cord and organs in the ventral body cavity • Attachment points of muscles, directs respiratory movements, and stabilizes portions of the appendicular skeleton • Consists of the skull, vertebral column, and thoracic cage
- 4. Appendicular Skeleton • Supports the attachment and functions of the upper and lower limbs of the human body, consists of the pectoral girdle, and the pelvic girdle • Pectoral girdle acts as an attachment point of the upper limbs of the body • Pelvic girdle acts as an attachment point of the lower limbs, bears the weight of the body, and is responsible for locomotion in a way • Upper limbs – arm, forearm, wrist and hand • Lower limbs – thighs, legs and feet
- 6. Types of Bones in the Human Body • flat bones • long bones • short bones • irregular bones • sesamoid bones
- 7. FLAT BONES • Function as protection for internal organs • Acts like a “shield” • Large area can provide muscle attachment points
- 8. Flat Bones Examples • Some bones in the skull (occipital, parietal, frontal, nasal, lacrimal and vomer) • Thoracic cage (sternum and ribs) • Pelvis (ilium, ischium, and pubis)
- 12. Long Bones • Function to support the weight of the body and facilitate movement • Mostly located in the appendicular skeleton • Mainly lower and upper limbs of the body
- 14. Short Bones • About as long as they are wide • Wrist and ankle joints • Provide stability and some movement
- 15. Irregular Bones • Vary in shape and structure, don’t fit into any other category • Often fairly complex in shape, and help protect internal organs • Vertebrae protect the spinal cord • Sacrum and Coccyx
- 17. Sesamoid Bones • Bones embedded in tendons • Small round bones usually found in the tendons of the hands, knees and feet. • Function to protect the tendons from stress and wear • Best Example is the Patella (kneecap)
