This document discusses theories of continental drift and seafloor spreading. It begins by outlining Alfred Wegener's continental drift theory, which proposed that Earth's continents were once joined together and have since drifted apart over millions of years. The document then covers the seafloor spreading theory proposed by Robert Dietz and Harry Hess, which suggested the ocean floors continuously spread due to volcanic activity at mid-ocean ridges, causing the continents to move. Evidence for continental drift discussed includes matching continental shelves, matching fossil distributions, and changing landforms and climates. The layers of Earth are also defined based on their chemical composition and physical properties.

Geodynamics
This document contains 55 questions related to geodynamics and plate tectonics. The questions cover a wide range of topics including the planetary evolution of Earth, continental drift evidence, plate boundary types, ocean floor spreading, seafloor features such as mid-ocean ridges and trenches, mountain building processes like collisional orogeny, and structural features of plate boundaries, continental rifts and volcanic island arcs. Several questions also focus on specific case studies like the Himalayas, Narmada rift valley, and ophiolites of the Indian subcontinent.
Plate tectonics
This document provides an overview of plate tectonics and types of plate boundaries. It defines plates as large, rigid slabs that move slowly over the asthenosphere. There are 6 major and 20 minor tectonic plates. Plates interact along boundaries where they converge, diverge, or move past each other, causing seismic and volcanic activity. The three main types of plate boundaries are divergence boundaries where plates move apart, convergence boundaries where they move together, and transform boundaries where they slide past each other.
Introduction to geodynamics
Geodynamics studies mantle convection and plate tectonics to understand phenomena like seafloor spreading and mountain building. It provides fundamentals for how the solid Earth works as a heat engine. Early theorists like Wegener and Du Toit proposed continental drift to explain geological similarities between continents. In the 1960s, seafloor mapping and studies of magnetic pole positions in rocks supported plate tectonics, where convection in the mantle drives the motion of rigid tectonic plates. This theory was accepted when it provided a unifying framework and mechanism to explain observations of geology and geophysics.
The Dynamic Earth
The document summarizes key facts about the dynamic Earth. It describes the different layers of the Earth including the crust, mantle, and core. The crust is divided into continental and oceanic crust of varying thicknesses. The mantle makes up most of the Earth's mass and is divided into lithosphere, asthenosphere, and mesosphere layers. The core is divided into a solid inner core and liquid outer core. The document also briefly outlines the Earth's rotation, revolution around the sun, and reasons for the seasons.

Earthquakes
Here are three questions from the section with the answers:
1. What causes convection currents in the mantle?
- Convection currents in the Earth are caused by the Earth's hot inner core heating the magma within the mantle.
2. What is a fault?
- A fault is a fracture, or break, in Earth's lithosphere. Rocks on either side can slide slowly along the fault or stick together, building stress until releasing in an earthquake.
3. Where do most earthquakes occur?
- About 80% of all earthquakes occur in a belt around the edges of the Pacific Ocean, near plate boundaries like the San Andreas Fault where the North American and Pacific plates meet.
The structure of the earth and plate tectonics
The Earth is composed of four main layers - the inner core, outer core, mantle, and crust. The crust is divided into tectonic plates that slowly move due to convection currents in the mantle. There are three types of plate boundaries - divergent where plates move apart, convergent where they move together, and transform where they slide past each other. Plate interactions at boundaries cause volcanic and seismic activity, with volcanoes and earthquakes concentrated near plate margins.
Plate tectonics
This document presents information on plate tectonics. It discusses the theory that the Earth's crust is broken into rigid plates that move over the mantle. The plates consist of the lithosphere and the asthenosphere acts as a plastic layer below. There are three main types of plate boundaries - divergent where plates move apart, convergent where they move together, and transform where they slide past each other. Plate movement causes landforms like rift valleys, mountain ranges, volcanoes and faults. Convection currents in the mantle provide the driving force that moves the plates.
Plate Tectonics 9
1) Earth's lithosphere is made up of tectonic plates that rest on the mantle and slowly move, dragging the plates along the surface.
2) There are three types of plate boundaries - divergent where plates move apart, convergent where plates collide, and transform where plates slide past each other horizontally.
3) Evidence like matching rock formations and fossils found on separated continents support Alfred Wegener's theory of continental drift that all land was once part of a single supercontinent called Pangea that has drifted apart over time.

What is Plate tectonics? In this presentation, you will be able to learn about Plate Tectonic Theory, the Plate Boundaries, as well as the Evidences of Plate Movement.
Plate Boundaries
This document discusses different types of plate boundaries. There are three main types: constructive boundaries, where plates move apart and new crust is formed; destructive boundaries, where plates converge and one plate is subducted under the other; and conservative boundaries, where plates slide past each other without being created or destroyed. Constructive boundaries include mid-ocean ridges, while destructive boundaries involve subduction zones and can result in volcanoes or mountain building. The key components of the lithosphere and how tectonic plates move due to convection currents in the mantle are also summarized.
Plate Tectonics
The Earth is divided into layers based on their chemical and physical properties. It has a solid iron core that makes up about 30% of the Earth's volume. Surrounding the core is the mantle, which is about 2,900km thick and comprises 70% of the volume. The crust is the outermost layer where life exists on Earth. The crust varies in thickness from 5-50km. It can be continental crust or oceanic crust. According to the theory of plate tectonics, the Earth's lithosphere is broken into plates that move slowly over time, which causes earthquakes at the plate boundaries.
Plate tectonics
1. Plate tectonics refers to the theory that the Earth's crust is divided into tectonic plates that slowly move and interact with one another.
2. The main types of plate boundaries are divergent boundaries where plates move apart, convergent boundaries where plates collide, and transform boundaries where plates slide past one another.
3. Key features associated with these boundaries include mountain building at convergent zones, volcanism and rifting at divergent zones, and strike-slip faulting along transform boundaries.
Chapter 28.1 modern geology
Geology is the study of Earth's rocks and materials. Nicholas Steno developed ideas in the 1600s about how rocks and fossils form using the analogy of shark teeth resembling stones found in rocks. These ideas formed the basis for relative dating techniques. Relative dating determines the order events occurred in by applying principles like superposition, original horizontality, lateral continuity, cross-cutting relationships, inclusions, and faunal succession to analyze rock layers and fossils. Earth's age was originally calculated to be between 10-100 million years but is now estimated at 4.6 billion years based on radioactive dating techniques.
Plate Tectonics
This document discusses plate tectonics and the geological evidence that supports the theory of plate tectonics. It covers topics such as the composition and structure of the Earth's interior, types of seismic waves, evidence that continents were once joined together in a supercontinent called Pangea, features of different types of plate boundaries like divergent and convergent boundaries, and how convection currents in the Earth's mantle drive the movements of tectonic plates.
Earthquakes ii
Earthquakes originate from a focus point within the earth and seismic waves travel outward, reaching the surface at the epicenter above the focus. Body waves including P-waves and S-waves originate at the focus and travel through the earth, while surface waves cause more damage when they reach the epicenter. Faults occur along tectonic plate boundaries and are classified as normal, reverse, or strike-slip depending on whether the rocks above the fault plane move down, up, or sideways relative to the other side.
Science Review Semester Final
The document summarizes key concepts in geology and ecology. It discusses the rock cycle and plate tectonics, including the four main types of plate boundaries and how they form different landforms. It also covers mineral hardness, pH scales, seasonal changes based on the Earth's position, predator-prey relationships in ecosystems, and the two main types of tides. Students are expected to know the definitions and be able to distinguish between related geological and biological concepts and apply them to multiple choice questions.

2) Sea floor spreading was proposed by Hess and coined by Robert Dietz, describing how new ocean crust forms along mid-ocean ridges as the plates spread apart.
3) Magnetic patterns in ocean crust provided evidence that Earth's magnetic poles switch polarity over time, recording a history of plate movements.

Plate Tectonics
Wegener first proposed continental drift in the early 20th century, suggesting that continents were once joined together in a supercontinent called Pangaea. While evidence like matching coastlines and fossil distributions supported drift, Wegener could not explain the forces driving plate motions. In the 1960s, the new theory of plate tectonics emerged, proposing that Earth's outer layer is broken into rigid plates that move over the mantle. At plate boundaries, plates diverge, converge, or slide past each other, creating geological features like mid-ocean ridges and subduction zones. Paleomagnetic and seafloor spreading evidence confirmed plate tectonics, and mantle convection is now understood to be the primary driver of
Prentice Hall Earth Science ch09 plate tectonics
This document provides an overview of plate tectonics and continental drift. It discusses Wegener's hypothesis of continental drift from 200 million years ago that formed the supercontinent Pangaea. It describes the three main types of plate boundaries: divergent boundaries where plates move apart, convergent boundaries where they crash together, and transform boundaries where they grind past each other. It also explains how mantle convection provides the driving force for plate motions and how this forms various landforms at the different plate boundary types.
Sea-Floor Spreading
1. The document discusses sea-floor spreading, which is the process where new oceanic crust forms at mid-ocean ridges as tectonic plates move away from each other.
2. Evidence that supports sea-floor spreading includes magnetic stripe patterns in the ocean floor and samples from ocean crust that show it is younger near ridges and older further away.
3. Oceanic crust is basaltic rock that forms at ridges and is then recycled in subduction zones, making it generally younger than continental crust which does not undergo this recycling process.
Chapter 10 ii
1) Scientists discovered underwater mountain ranges called mid-ocean ridges using sound waves, and Harry Hess proposed the theory of seafloor spreading to explain them.
2) Seafloor spreading involves hot material rising at ridges and flowing sideways, carrying the seafloor away as new material cools and forms at the cracks.
3) Evidence for seafloor spreading includes younger rocks at ridges and magnetic reversals recorded in strips of rock parallel to ridges.
Plate Tectonics - Chapter 5
Geologists have learned about Earth's interior through examining rock samples and studying seismic waves. Temperature and pressure both increase with depth inside Earth. The crust and mantle are divided into layers with different physical properties. Convection currents in the mantle are driven by heat from the core and cause the tectonic plates to slowly move over time. The theory of plate tectonics explains how new crust forms at mid-ocean ridges and old crust is recycled into the mantle at subduction zones, causing the plates to drift apart or collide together over hundreds of millions of years.

The theory of plate tectonics emerged, stating that the Earth's lithosphere is broken into plates that move over the asthenosphere. The boundaries between plates can be divergent, convergent, or transform. Plate motions are driven by convection currents in the Earth's mantle.

WHAT IS A PLATE?
Major continental and oceanic plates include:
Types of Earth’s Crust:
Plate tectonics (from the Late Latin tectonicus) is a scientific theory which describes the large scale motions of Earth's lithosphere.
THE DYNAMIC EARTH:
The earth is a dynamic planet, continuously changing both externally and internally. The earth’s surface is constantly being changed by endo-genetic processes resulting in volcanism and tectonism, and exogenetic processes such as erosion and deposition. These processes have been active throughout geological history. The processes that change the surface feature are normally very slow (erosion and deposition) except some catastrophic changes that occur instantaneously as in the case of volcanism or earthquakes. The interior of the earth is also in motion. Deeper inside the earth, the liquid core probably flows at a geologically rapid rate of a few tenths of mm/s. Several hypotheses attempted to explain the dynamism of the earth.
+ Horizontal movement hypothesis
+ Continental drift, displacement hypothesis
Development of the plate tectonic theory.
Plate tectonic theory arose out of the hypothesis of continental drift proposed by Alfred Wegener in 1912. He suggested that the present continents once formed a single land mass that drifted apart, thus releasing the continents from the Earth's core and likening them to "icebergs" of low density granite floating on a sea of denser basalt.
Seafloor Spreading
The first evidence that the lithospheric plates did move came with the discovery of variable magnetic field direction in rocks of differing ages.
Seafloor spreading theory discuss 3
1. Harry Hess proposed the theory of seafloor spreading in 1962, which provided evidence that Wegener's theory of continental drift was correct. Hess theorized that new ocean crust is formed at mid-ocean ridges through volcanic eruptions and then spreads outwards, pushing older crust farther away.
2. Evidence for seafloor spreading includes rock formations only possible from cooled lava, magnetic stripe patterns in ocean crust recording reversals of Earth's magnetic field, and drilling samples showing younger rock nearer to ridges.
3. Seafloor spreading is driven by convection currents in the Earth's mantle; subduction zones allow parts of ocean crust to sink back into the mantle and regulate ocean size.
CONTINENTAL DRIFT HYPOTHESIS
This document discusses evidence that supports continental drift and plate tectonics theories. It describes how the Earth's crust is divided into plates that move over time, occasionally colliding or splitting apart. Fossil, rock formation, and climate data from separated continents provided early evidence that landmasses have drifted over hundreds of millions of years. Studies of the ocean floor revealed patterns of magnetic polarity reversals and symmetrical magnetic strips that supported the hypothesis of sea floor spreading at mid-ocean ridges, with new crust forming and pushing older crust farther outward over time. Together this evidence established plate tectonics as the mechanism explaining continental movement and geological phenomena like earthquakes and volcanoes.
2013 updated plate tectonics new one use this one
The document summarizes plate tectonics and the development of the theory. It describes how early scientists like Wegener proposed continental drift but lacked evidence. Later, mapping of the ocean floor revealed patterns of magnetic stripes and rock ages indicating the seafloor spreads from mid-ocean ridges. This led scientists in the 1960s to develop the modern theory of plate tectonics, which proposes that Earth's crust is divided into plates that move due to convection currents in the mantle.
Sea floor spreading
The document summarizes evidence that supports the theory of seafloor spreading and plate tectonics. It describes how Harry Hess first proposed in 1962 that new ocean crust is formed at mid-ocean ridges through volcanic activity and magma cooling. As more magma is added, it pushes older ocean crust further from the ridges, providing evidence that the plates are moving. Studies of magnetic reversals in ocean floor basalts also indicate the age of the crust increases further from ridges, confirming seafloor is continually being created and destroyed over time.
Notes: Continental Drift Plate Tectonics
Here are the answers to the questions:
1. Divergent boundary - Mid-ocean ridge. New ocean floor is created as the plates move apart and magma rises to fill the gap.
2. Convergent boundary - Subduction zone. One plate moves under the other and is recycled back into the mantle. Volcanoes and earthquakes occur above the subducting slab.
3. Transform boundary - San Andreas Fault. The plates slide past each other, causing earthquakes along the fault line.
Plate tectonics
Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the lithosphere.

It discusses key topics such as continental drift, Earth's layered structure, types of plate boundaries including convergent, divergent and transform boundaries, seafloor spreading, plate motions, and forces driving plate tectonics. The objectives are to understand concepts like continental drift, Earth's structure, plate margins, seafloor spreading, how plates move on the surface of the sphere, and driving forces. Diagrams and figures are included to illustrate these topics.
Deformation-of-the-Crust-and-Plate-Tectonics.pdf
This document discusses the theory of plate tectonics and the movement of tectonic plates. It describes how early theories like catastrophism were replaced by uniformitarianism. It then explains how the theory of continental drift was proposed and how evidence from paleomagnetism supported it. It discusses how seafloor spreading was discovered through mapping of the seafloor and analysis of magnetic properties in the rocks. This led to the modern theory of plate tectonics, where lithospheric plates move through divergent, convergent, and transform boundaries. The movement of plates has shaped continents over geologic time.
Geology: Plate Tectonics
Plate Tectonic is a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
Earth&PlateTectonics_Butler_ERBmod.ppt
The document discusses plate tectonics and the evidence that supports the theory. It explains that the Earth's crust is broken into plates that move relative to each other. There are three main types of plate boundaries: divergent, convergent, and transform. Evidence for plate tectonics includes the locations of earthquakes and volcanoes along plate boundaries, as well as the movement of continents over geologic time as described by Alfred Wegener's theory of continental drift.

Plate tectonics theory proposes that Earth's outermost layer is broken into rigid tectonic plates that constantly move atop the asthenosphere in response to convection currents in the mantle, interacting along plate boundaries through divergent, convergent, and transform motion that creates geologic features like mid-ocean ridges, trenches, volcanoes, and earthquakes. Mapping of the seafloor revealed evidence like magnetic stripes and the ages of rocks that supported seafloor spreading and subduction, leading scientists in the 1960s to combine these ideas with continental drift into the unified theory of plate tectonics.

Kuliah GL-3 (Plate Tec).ppt
Earth's surface is divided into tectonic plates that move over time. Heat from radioactive decay in Earth's interior drives convection currents in the mantle, providing the force that pushes plates together or pulls them apart at boundaries. Evidence from seismic waves, the distribution of ocean sediments and magnetic patterns on the seafloor have confirmed plate tectonic theory and helped explain features like mid-ocean ridges, volcanoes, and earthquake zones. Plate tectonics unifies many fields of geology by explaining the formation of continents, oceans, and mountain ranges over billions of years.
Earth&PlateTectonics_Butler_ERBmod.ppt
The document discusses plate tectonics and provides evidence that supports the theory of continental drift. It describes how the Earth's crust is broken into plates that move relative to each other. The plates interact in different ways as they move, including colliding, pulling apart, and scraping past one another, which causes geological features like mountains and volcanoes to form. It also explains Alfred Wegener's early theory of continental drift and the fossil, geological, and geographical evidence he used to support the idea that the continents were once joined together in a supercontinent called Pangaea.
Plate tectonics
The document discusses plate tectonics and the evidence supporting continental drift. It describes how Wegener first proposed the hypothesis of continental drift in 1912 based on observations that the continents seemed to fit together. The document outlines several pieces of evidence that supported Wegener's hypothesis, including matching coastlines, shared fossil distributions, and geological and climatic similarities between separated continents. It then describes how the theory of seafloor spreading provided further evidence when studies in the 1940s and 1950s showed the ocean floor was younger than the continents and spreading occurred at mid-ocean ridges. Paleomagnetic data from the seafloor also supported seafloor spreading and continental drift. Today the theory of plate tectonics unifies
Distribution of oceans and continents
The document summarizes the theory of plate tectonics. It discusses how early scientists like Wegener proposed the idea of continental drift and Pangaea. Later evidence from mapping ocean floors and magnetic stripes on ocean crust supported sea floor spreading and plate tectonics. The theory states the earth's outer layer is divided into plates that constantly move via three types of boundaries: divergent where plates move apart, convergent where they push together, and transform where they slide past each other. The movement of plates like India colliding with Asia helped form features like the Himalayas.

Types of Rocks
This document discusses different types of rocks including igneous, sedimentary, and metamorphic rocks. It explains that igneous rocks form from solidified magma and can be extrusive or intrusive depending on their cooling rate. Sedimentary rocks form from compressed and cemented sediments. Metamorphic rocks form from existing rocks undergoing changes in temperature and pressure. The rock cycle shows how the different rock types can transform into one another over time through geological processes.
Earth as Unique Planet
The document discusses the Earth's unique characteristics that make it habitable and able to support life. It focuses on three key aspects: the presence of liquid water, heat sources, and the atmosphere. Liquid water is essential for life and was brought to Earth by comets or volcanism. The Earth exists within the habitable zone of the Sun where water can be liquid. Heat sources both internally from the Earth's core and externally from the Sun allow life-sustaining temperatures. The atmosphere supports photosynthesis, regulates gases and temperature, and its existence is due to the Earth's gravity holding it in place.
Theories of Solar System's Formation and Structure
The document discusses theories about the formation of the solar system. It describes the Nebular Hypothesis theory, which states that the solar system originated from a large cloud of gas and dust that contracted due to gravity, forming denser pockets that began rotating and heating up. Most material ended up in the center to form the sun, while the rest flattened into a disk that circled it and formed the planets. It also describes the earlier Encounter Hypothesis theory and problems with it, and discusses geocentric and heliocentric models of the structure of the early solar system.
Theories of the Origin of the Universe
The document discusses several theories about the origin of the universe, focusing on explaining the Big Bang theory. This theory proposes that the universe began around 14 billion years ago from an infinitely tiny, dense point known as a singularity, and has been expanding ever since. Key evidence for the Big Bang theory includes Hubble's law, which describes that galaxies appear to be moving away from Earth and the farther away they are the faster they recede.

Studies show the Philippines has a demand for child pornography and it remains prevalent due to poverty and corruption. Technology has increased accessibility online.
Endocrine System and Exocrine Glands
The document discusses how the endocrine system allows organs to communicate through hormones. It explains that endocrine glands secrete hormones directly into the bloodstream, which then carry messages to target organs. The target organs are programmed to receive specific hormones and carry out instructions like producing acids or cells. This allows the endocrine system to regulate and maintain homeostasis in the body.
Hormones
The document discusses various topics related to hormones and their functions in the human body. It defines growth hormone and the condition of gigantism caused by its overproduction. It also discusses hormones involved in the fight-or-flight response like adrenaline and cortisol. Additional topics covered include hormones that influence hair growth, eye color, metabolism, voice changes, and more.
Sexually Transmitted Diseases (STDs)
This document discusses sexually transmitted diseases (STDs). It defines STDs as infections passed between people through sexual activity. STDs can be caused by bacteria, viruses, or parasites. They are transmitted through various sexual behaviors and bodily fluids. Common STDs like chlamydia, herpes, gonorrhea, HPV, and HIV/AIDS are explained. The document outlines methods of prevention like abstinence and condom use and states that while antibiotics can cure bacterial STDs, viral STDs have no cure. It provides overview information about STDs to educate people.
Weather Extremes
The document discusses various weather phenomena that affect the Philippines, including typhoons, thunderstorms, tornadoes, storm surge, lightning, monsoons, and rainfall.

It notes benefits and effectiveness of different natural and artificial family planning techniques.
Stages of Infection
The document discusses the stages of infectious disease progression:
1. Incubation period is when the pathogen multiplies without symptoms and the person can spread the disease.
2. Prodrome period is when the person may begin feeling ill as the immune system responds.
3. Illness period is when signs and symptoms peak as the disease is in full effect.
4. Decline period is when the immune system gains control and symptoms lessen.
5. Recovery period is when the pathogen is eliminated and the person returns to normal.
Types of Faults
This document provides information about earthquake terminology and fault lines in the Philippines. It defines key terms like epicenter, hypocenter, fault plane, and fault zone. It also lists the major fault lines in the country, including the Marikina Valley Fault, Western Philippine Fault, and Central Philippine Fault. Different types of faults are described based on the displacement of plates and the orientation of the fault, including dip-slip, strike-slip, and oblique-slip faults.
Emerging and Re-emerging Diseases
Leptospirosis is a bacterial infection spread through contact with infected animal urine that can cause fever, headache, jaundice and other symptoms. It is more common in warm climates and transmitted through breaks in the skin or mucous membranes. Antibiotics are used to treat it, with more severe cases requiring hospitalization.
Severe Acute Respiratory Syndrome (SARS) is a viral pneumonia caused by a coronavirus. It is spread through droplets from coughs or sneezes of infected individuals or surfaces they touch. Prevention methods include handwashing, wearing masks around infected people, and disinfecting surfaces.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

In this book, we use conservation of energy techniques on a fluid element to derive the Modified Bernoulli equation of flow with viscous or friction effects. We derive the general equation of flow/ velocity and then from this we derive the Pouiselle flow equation, the transition flow equation and the turbulent flow equation. In the situations where there are no viscous effects , the equation reduces to the Bernoulli equation. From experimental results, we are able to include other terms in the Bernoulli equation. We also look at cases where pressure gradients exist. We use the Modified Bernoulli equation to derive equations of flow rate for pipes of different cross sectional areas connected together. We also extend our techniques of energy conservation to a sphere falling in a viscous medium under the effect of gravity. We demonstrate Stokes equation of terminal velocity and turbulent flow equation. We look at a way of calculating the time taken for a body to fall in a viscous medium. We also look at the general equation of terminal velocity.
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.
