Equine diseasessflansburg02Colic is a common equine disease characterized by abdominal pain. Signs include lying down more than usual, repeated getting up and lying down, pawing at the abdomen, and kicking at the abdomen. Treatment involves passing a nasogastric tube to relieve pain and check stomach contents, administering pain medication, and potentially surgery if pain is not responsive. Surgery is considered based on factors like history, reflux, rectal exam findings, and response to analgesia. Laminitis presents with lameness and a history of excessive grain intake or endotoxemia. Strangles is caused by Streptococcus equi and signs include fever, mucopurulent nasal discharge, and abscessation of lymph nodes.
Automic Structure Jnana Prabodhini Educational Resource CenterThe document discusses the structure of an atom. It explains that an atom contains protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit the nucleus. John Dalton, J.J. Thomson, and Ernest Rutherford contributed theories to our understanding of atomic structure through experiments. Rutherford determined that the nucleus is very small and contains a positive charge, with electrons orbiting the outside. The number of protons defines the atomic number of an element.
Circulation of BloodJnana Prabodhini Educational Resource CenterThe document summarizes the human circulatory system. It has three main parts: blood vessels, heart, and blood. The heart pumps blood through arteries and veins to circulate oxygen and nutrients to tissues through networks of capillaries. It then returns deoxygenated blood back to the heart. The circulatory system allows for the transportation of substances around the body through continuous circulation facilitated by the heart's regular pumping action.

Farming 1Jnana Prabodhini Educational Resource CenterAn experiment in sustainable farming was launched in rural India to address the issues of farmer suicides, destitution of families, and burden on women and children. The Magan Sanghralaya Samiti started a natural farming movement in Wardha district of Maharashtra to provide an alternative to problems caused by genetically modified seeds, such as increased pest infestation and dying trees. The movement aims to give voice to farmers whose concerns have gone unheard.
DesertJnana Prabodhini Educational Resource CenterThe Great Indian Desert, also known as the Thar Desert, is located in northwestern India. It is one of the largest subtropical deserts in the world, covering an area of over 200,000 square kilometers across the Indian states of Rajasthan, Haryana, Punjab, and Gujarat. The desert is mostly an undulating sandy plain covered with crescent-shaped sand dunes, and it has an arid climate with low vegetation due to low annual precipitation of less than 250 millimeters.
Measurement EstimationJnana Prabodhini Educational Resource CenterThe document discusses measurement accuracy. Some measurements like vegetables and distances can be estimated, while others like gold, medicines, and machine parts need to be accurate. The required level of accuracy depends on the purpose of measurement. Advances in technology now allow for more accurate measurement of things like time, distance, mass, and chemical compositions. However, mistakes can still occur due to limitations of instruments or observer negligence. Laws and regulations aim to prevent inaccurate measurements from cheating customers.
Automic structureJnana Prabodhini Educational Resource Center- Atoms are the smallest particles of matter and consist of electrons, protons, and neutrons. Protons and neutrons are located in the nucleus, while electrons orbit the nucleus.
- Rutherford's gold foil experiment showed that atoms are mostly empty space, with a small, dense nucleus at the center containing positive charge. Electrons orbit the nucleus.
- An atom's atomic number is the number of protons, which determines the element. The mass number is the total number of protons and neutrons. Isotopes are atoms of the same element with different numbers of neutrons.
Digestive systemJnana Prabodhini Educational Resource CenterCarbohydrates, proteins, and fats are broken down by digestive enzymes into smaller molecules like glucose, amino acids, and fatty acids in order to be absorbed by the small intestine. The digestive system includes the mouth, esophagus, stomach, small intestine, large intestine, and anus. Various digestive juices containing enzymes are produced and released by the salivary glands, stomach, pancreas, and small intestine to break down food into absorbable molecules.
Vivek inspireJnana Prabodhini Educational Resource CenterThis document outlines a program to identify and nurture gifted children in remote areas of Arunachal Pradesh, India. It notes the challenges of remoteness, difficult terrain, and lack of resources and awareness. The program will identify gifted students using informal and formal assessments, provide them training and experiences through workshops, and develop their skills in areas like mental ability, creativity, and problem solving. Mentors will be trained to continue the program between workshops. The goals are for students to succeed in academics and competitions, develop holistically, and become leaders representing their state. Challenges include remoteness, lack of awareness, overburdened mentors, and maintaining consistent contact.

PSA Exam Pattern Jnana Prabodhini Educational Resource CenterThe document provides information about the Central Board of Secondary Education's (CBSE) Problem Solving Assessment (PSA) for classes 9 and 11. The PSA will assess skills like quantitative reasoning, qualitative reasoning, language conventions, critical thinking, problem solving and communication. It will count for 10% of the total class 9 assessments and the score will carry forward to class 10 where students can improve their score. The 60 minute multiple choice test will be administered in schools on February 14, 2013 and will consist of 60 questions assessing areas like quantitative reasoning, qualitative reasoning and language conventions.
Food and Nutrition Jnana Prabodhini Educational Resource Center1. All living things require food for growth and repair, though plants can produce their own food through photosynthesis while animals and some other organisms obtain food from other living things.
2. Food provides organisms with nutrients like carbohydrates, proteins, fats, vitamins, minerals, and water which are broken down and absorbed for energy, growth and cell repair.
3. Digestion and absorption of food occurs through different processes depending on whether an organism is unicellular like an amoeba or multicellular like humans and animals, but all involve the breakdown of food into simpler compounds that can be used by the cells of the body.
Food and preservation of food Jnana Prabodhini Educational Resource CenterThe document discusses food preservation and adulteration. It explains that food preservation aims to make food available throughout the year by storing it in ways that maintain quality. Common preservation methods include drying grains, boiling liquids, refrigerating or freezing perishables, and using salts, spices, oils or sugars to preserve items like pickles. Adulteration involves mixing high quality food with lower quality ingredients, which can harm health. Governments regulate food to prevent adulteration.
Reproduction in Living ThingsJnana Prabodhini Educational Resource Center1. Reproduction is a natural process that allows living things to produce offspring of the same type in order to perpetuate their species.
2. Living things can reproduce sexually, with male and female gametes, or asexually without sex organs through various vegetative, spore-forming, budding, or fragmentation methods.
3. Sexual reproduction in plants involves pollen transfer for fertilization to produce seeds containing embryos that grow into new plants, while animals sexually reproduce through internal fertilization leading to offspring that receive nourishment initially through eggs or live birth.
The Organisation of Living Things Jnana Prabodhini Educational Resource CenterThe document discusses the organization of living things from the cellular level to the ecosystem level. It explains that living things are organized in a hierarchical manner, from cells to tissues to organs to organ systems to organisms and finally populations within an ecosystem. At each level, the parts work together interdependently to carry out functions necessary for life. The ecosystem level represents the broadest level of organization, where living things interact with each other and their non-living environment.
Effects of HeatJnana Prabodhini Educational Resource CenterHeat causes materials to change between solid, liquid and gas states. Solids expand and become fluids when heated, liquids boil and become gases, and gases expand. Materials change states at specific temperatures. State changes can also be caused by removing heat. The temperature at which a material changes state is unique to that material. Heat causes all materials to expand and contract with temperature change.
Motion and Types of motionJnana Prabodhini Educational Resource CenterThis document discusses different types of motion. It defines speed as the distance traveled in a specific time. There are several types of motion including linear motion, oscillation motion, rotary motion, irregular motion, and circular motion. Linear motion involves traveling in a straight line at a constant or varying speed. Oscillation motion refers to movement from one end point to another and back again. Rotary motion is when an object passes through the same point while rotating.
Electric ChargeJnana Prabodhini Educational Resource CenterStatic electric charge develops when objects are rubbed together, such as a plastic comb rubbed through hair. This causes an imbalance of electric particles between the two objects. Glass develops a positive charge when rubbed with silk, while ebonite becomes negatively charged when rubbed with wool. Like charges repel each other, while unlike charges attract. The electroscope can detect electric charge by the separation of its gold leaves when a charged object touches it.
Transmission of HeatJnana Prabodhini Educational Resource CenterHeat can be transferred through three methods: conduction, convection, and radiation. Conduction involves the transfer of heat between particles in direct contact through vibrations. Convection occurs through the circulation of hotter and colder parts of a fluid. Radiation transfers heat through electromagnetic waves and does not require a medium. Thermos flasks and containers help retain the temperature of foods and drinks by trapping air between layers of glass or plastic that act as insulators to prevent heat transfer by conduction, convection, or radiation.
Propagation of SoundJnana Prabodhini Educational Resource CenterThis document is comprised of 15 pages that are each copyrighted by the Jnana Prabodhini Educational Resource Centre. No other substantive information is provided.
Propagation of Light Jnana Prabodhini Educational Resource Center1. Light travels in a straight line and can be reflected. When light hits a non-transparent object, it changes direction rather than passing through. The reflected light then reaches our eyes, allowing us to see objects.
2. Experiments can demonstrate the linear propagation of light using a laser, tubes, cardboard with holes, or observing dust particles in a beam of light. Light will only pass through holes that are aligned.
3. Shadows are formed when a light source is blocked by an object. A point light source will create a dark umbra shadow, while an extended source makes both a dark umbra and a faint penumbra shadow. Solar and lunar eclipses occur through the formation of shadows
Natural ResourcesJnana Prabodhini Educational Resource CenterThe document discusses natural resources and their classification. It defines natural resources as things through which man's basic needs are met, including air, water, soil, minerals, plants and animals. Renewable resources like plants and animals can reproduce and regrow when destroyed. Non-renewable resources like air, water and soil cannot be reproduced and their supplies are limited. The document emphasizes the importance of conserving both renewable and non-renewable natural resources and provides suggestions for reducing pollution and practicing sustainable use.
Characteristics of Living ThingsJnana Prabodhini Educational Resource CenterLiving things have several key characteristics: they are made of one or more cells, can move on their own, respond to their environment, grow and develop, reproduce, require food and oxygen, and experience a life cycle from birth to death. Non-living things do not possess these characteristics and are not made of cells.
The earth and its living worldJnana Prabodhini Educational Resource CenterThe document describes the four main spheres that make up the Earth - the lithosphere, hydrosphere, atmosphere, and biosphere. It provides details about each sphere: the lithosphere includes the planet's land and crust; the hydrosphere contains all water on Earth's surface and underground; the atmosphere surrounds the planet as a mixture of gases; and the biosphere is made up of all living things that exist within the other spheres. It also gives examples of specific landforms, bodies of water, atmospheric layers, and organisms that are part of each sphere.
