Parts of Microscope 1. Arm It is in the back of the microscope and supports the objectives and ocular. Also, it is the part that we use to carry or lift it. 2. Base It’s the bottom of the scope. In addition, it houses the light source and the back section of base acts as a handle to carry the scope. 3. Course Focusing Knob We use it to adjust the position of objective lenses. Also, this should be done keeping in mind that the objective should not hit the slide. In addition, it should be stopped when the object is completely visible through the ocular. 4. Fine Focusing Knob We use it to bring the specimen in perfect focus once the specimen is visible through the course-focusing knob. Also, focus slowly to avoid contact between the objective and the specimen. 5. Illuminator It is the light source of the microscope. 6. Numerical Aperture or Objective lens It is found in a compound scope and is the lens that is closest to the specimen. 7. Ocular Lens This is the lens closest to the viewer in a compound light microscope. 8. Oil immersion Lens This is a 100x (100 times) objective lens. Also, this lens is small in order to attain high resolution and magnification. Furthermore, due to its size, it is important for the lens to get as much light as possible. Moreover, by immersion of lens in oil it eliminates the refraction of light, it happens because the glass and oil have almost the same refractive index. Most noteworthy, in this way the light is maximized and gives the clearest image. Besides, It oil immersion lens is used without oil then the produced Image will become unclear and has a poor resolution.Translator: Joseph Geni Reviewer: Morton Bast Before March, 2011, I was a photographic retoucher based in New York City. We're pale, gray creatures. We hide in dark, windowless rooms, and generally avoid sunlight. We make skinny models skinnier, perfect skin more perfect, and the impossible possible, and we get criticized in the press all the time, but some of us are actually talented artists with years of experience and a real appreciation for images and photography. On March 11, 2011, I watched from home, as the rest of the world did, as the tragic events unfolded in Japan. Soon after, an organization I volunteer with, All Hands Volunteers, were on the ground, within days, working as part of the response efforts. I, along with hundreds of other volunteers, knew we couldn't just sit at home, so I decided to join them for three weeks. On May the 13th, I made my way to the town of Ōfunato. It's a small fishing town in Iwate Prefecture, about 50,000 people, one of the first that was hit by the wave. The waters here have been recorded at reaching over 24 meters in height, and traveled over two miles inland. As you can imagine, the town had been devastated. We pulled debris from canals and ditches. We cleaned schools. We de-mudded and gutted homes ready for renovation and rehabilitation. We cleared tons and tons of stinking, rotting fish carcasses from the local fish processing plant. We got dirty, and we loved it. For weeks, all the volunteers and locals alike had been finding similar things. They'd been finding photos and photo albums and cameras and SD cards. And everyone was doing the same. They were collecting them up, and handing them in to various places around the different towns for safekeeping. Now, it wasn't until this point that I realized that these photos were such a huge part of the personal loss these people had felt. As they had run from the wave, and for their lives, absolutely everything they had, everything had to be left behind. At the end of my first week there, I found myself helping out in an evacuation center in the town. I was helping clean the onsen, the communal onsen, the huge giant bathtubs. This happened to also be a place in the town where the evacuation center was collecting the photos. This is where people were handing them in, and I was honored that day that they actually trusted me to help them start hand-cleaning them. Now, it was emotional and it was inspiring, and I've always heard about thinking outside the box, but it wasn't until I had actually gotten outside of my box that something happened. As I looked through the photos, there were some were over a hundred years old, some still in the envelope from the processing lab, I couldn't help but think as a retoucher that I could fix that tear and mend that scratch, and I knew hundreds of people who could do the same. So that evening, I just reached out on Facebook and asked a few of them, and by morning the response had been so overwhelming and so positive, I knew we had to give it a go. So we started retouching photos. This was the very first. Not terribly damaged, but where the water had caused that discoloration on the girl's face had to be repaired with such accuracy and delicacy. Otherwise, that little girl isn't going to look like that little girl anymore, and surely that's as tragic as having the photo damaged. (Applause) Over time, more photos came in, thankfully, and more retouchers were needed, and so I reached out again on Facebook and LinkedIn, and within five days, 80 people wanted to help from 12 different countries. Within two weeks, I had 150 people wanting to join in. Within Japan, by July, we'd branched out to the neighboring town of Rikuzentakata, further north to a town called Yamada. Once a week, we would set up our scanning equipment in the temporary photo libraries that had been set up, where people were reclaiming their photos. The older ladies sometimes hadn't seen a scanner before, but within 10 minutes of them finding their lost photo, they could give it to us, have it scanned, uploaded to a cloud server, it would be downloaded by a gaijin, a stranger, somewhere on the other side of the globe, and it'd start being fixed. The time it took, however, to get it back is a completely different story, and it depended obviously on the damage involved. It could take an hour. It could take weeks. It could take months. The kimono in this shot pretty much had to be hand-drawn, or pieced together, picking out the remaining parts of color and detail that the water hadn't damaged. It was very time-consuming. Now, all these photos had been damaged by water, submerged in salt water, covered in bacteria, in sewage, sometimes even in oil, all of which over time is going to continue to damage them, so hand-cleaning them was a huge part of the project. We couldn't retouch the photo unless it was cleaned, dry and reclaimed. Now, we were lucky with our hand-cleaning. We had an amazing local woman who guided us. It's very easy to do more damage to those damaged photos. As my team leader Wynne once said, it's like doing a tattoo on someone. You don't get a chance to mess it up. The lady who brought us these photos was lucky, as far as the photos go. She had started hand-cleaning them herself and stopped when she realized she was doing more damage. She also had duplicates. Areas like her husband and her face, which otherwise would have been completely impossible to fix, we could just put them together in one good photo, and remake the whole photo. When she collected the photos from us, she shared a bit of her story with us. Her photos were found by her husband's colleagues at a local fire department in the debris a long way from where the home had once stood, and they'd recognized him. The day of the tsunami, he'd actually been in charge of making sure the tsunami gates were closed. He had to go towards the water as the sirens sounded. Her two little boys, not so little anymore, but her two boys were both at school, separate schools. One of them got caught up in the water. It took her a week to find them all again and find out that they had all survived. The day I gave her the photos also happened to be her youngest son's 14th birthday. For her, despite all of this, those photos were the perfect gift back to him, something he could look at again, something he remembered from before that wasn't still scarred from that day in March when absolutely everything else in his life had changed or been destroyed. After six months in Japan, 1,100 volunteers had passed through All Hands, hundreds of whom had helped us hand-clean over 135,000 photographs, the large majority — (Applause) — a large majority of which did actually find their home again, importantly. Over five hundred volunteers around the globe helped us get 90 families hundreds of photographs back, fully restored and retouched. During this time, we hadn't really spent more than about a thousand dollars in equipment and materials, most of which was printer inks. We take photos constantly. A photo is a reminder of someone or something, a place, a relationship, a loved one. They're our memory-keepers and our histories, the last thing we would grab and the first thing you'd go back to look for. That's all this project was about, about restoring those little bits of humanity, giving someone that connection back. When a photo like this can be returned to someone like this, it makes a huge difference in the lives of the person receiving it. The project's also made a big difference in the lives of the retouchers. For some of them, it's given them a connection to something bigger, giving something back, using their talents on something other than skinny models and perfect skin. I would like to conclude by reading an email I got from one of them, Cindy, the day I finally got back from Japan after six months. "As I worked, I couldn't help but think about the individuals and the stories represented in the images. One in particular, a photo of women of all ages, from grandmother to little girl, gathered around a baby, struck a chord, because a similar photo from my family, my grandmother and mother, myself, and newborn daughter, hangs on our wall. Across the globe, throughout the ages, our basic needs are just the same, aren't they?" Thank you. (Applause) (Applause)Agriculture Agriculture is the main source of livelihood in every country in the region except Brunei and Singapore. Agricultural employment, however, has been declining. More than two-thirds of the workforces of Cambodia and Laos practice agriculture. As the economies of the ASEAN countries have been restructured toward growth in industry and services, there has been a corresponding decline in the proportion of the gross domestic product (GDP) derived from agriculture, most significantly in Indonesia, Malaysia, and Thailand. Agricultural output in Southeast Asia has increased significantly since 1970. There are wide variations in this growth across the region, with the greatest gains in Malaysia and Thailand and little or no increase in Cambodia, Laos, and Vietnam. Hunger and malnutrition are problems in pockets of even the most developed countries, but they have been especially serious in Cambodia because of crop failures and internal strife. The condition of the rural population everywhere is clearly related to limited access to land, the landless experiencing greater poverty and poorer health. Landlessness is perhaps most serious in the Philippines. The dominant form of agriculture in the region is wet-rice cultivation. Where conditions permit, two crops typically are planted each year. Other food crops such as corn (maize), cassava, and pulses (legumes) frequently are grown in drier areas where there is too little water for a second planting of rice. Rice production requires a reliable water supply. Thailand and the Philippines rely heavily on rain-fed systems, while Indonesia utilizes irrigation to a large extent. Irrigation or some other form of water control is especially critical in the cultivation of the high-yielding varieties (HYVs) of rice that have been introduced since the 1960s. The spread of the so-called Green Revolution—in which HYVs and chemical fertilizers and pesticides are utilized—has brought mixed results. There is little doubt that production has increased because of the higher yields of these hybrid strains and because their more rapid maturation increases the possibility of multiple annual crops. Frequently, however, poorer farmers are not able to take advantage of these strains, because of the high cost of their use. The goal of rice self-sufficiency has been difficult to achieve for most countries. A large variety of cash crops are grown for the local and export markets, both on large commercial estates and by individual growers or smallholders. Tree crops are the most important in terms of value, although the area devoted to them is limited largely to equatorial areas. Rubber and palm oil are significant in Malaysia, Indonesia, and southern Thailand, while coconuts and sugar are important in the Philippines. Other major export crops are cacao, coffee, and spices, while crops grown largely for local and regional consumption include chilies, sweet potatoes, peanuts (groundnuts), and tobacco. The cultivation of opium poppies is important in parts of Myanmar and Thailand. The emphasis on rubber and palm oil production is in response to a considerable (though fluctuating) worldwide demand for these commodities and because of a nearly continuous harvest period that provides year-round employment. Foreign corporations once dominated production, but, as the region’s countries gained independence, much of the production was nationalized. Government ownership continues to predominate, with increasing private ownership. Fishing contributes only a token amount to the GDP of Southeast Asian countries, but it is an important livelihood in certain areas and supplies a significant portion of the local diet. Marine output has gradually expanded with new technologies. The maritime nations of Thailand, Indonesia, Malaysia, and the Philippines all have globally important fishing industries. Shrimp catches are especially in demand in the world economy. Aquaculture has become increasingly important in the region, such species as shrimp, carp, and grouper being raised in excavated ponds.💰 Impact on the Economy Natural resources play a major role in the growth of a country’s economy. Here’s how: Source of Income and Employment Many people work in industries like mining, farming, fishing, and forestry. These sectors create jobs and help reduce poverty. Industrial Growth Raw materials like iron, coal, and oil are used in industries to make products such as steel, vehicles, and energy. More industries mean more production and trade. Energy Production Resources like coal, oil, gas, and sunlight are used to produce electricity. Energy supports factories, transportation, and homes. Exports and Foreign Exchange Countries export natural resources (like crude oil, gold, or coffee) to earn money from other countries. This increases national income. Infrastructure Development Resource wealth helps governments build roads, schools, and hospitals. ⚠️Camshaft: A rotating shaft in an engine that controls the opening and closing of the intake and exhaust valves.

Sharks have lived in the oceans since before dinosaurs walked on Earth. Hundreds of kinds of sharks can be found all over the world. Sharks are fish, but their skeletons are made of cartilage instead of bones. Cartilage is what gives human ears their shape. Unlike most fish, sharks have rough skin. Sharks have a good sense of smell. They also see well in the dark. Sharks can sense other animals moving in the water. Description. Great white shark come in many sizes. Some sharks are only a few inches long. The huge whale shark is the largest fish in the world. Many sharks are dark on the top and light on the bottom. This shading makes it harder for other animals to see them. Sharks swim by swinging their tails from side to side. Fins help sharks steer, turn, and keep their balance. Eating. Most sharks have many rows of teeth. When one tooth breaks off, another one moves up to take its place. Most sharks eat fish. Large sharks eat sea lions, dolphins, and other sharks. Some sharks eat shellfish. These sharks have flat teeth for crushing shells. The huge whale shark has tiny teeth but doesn't use them when eating. It swallows very small ocean plants and animals that float near the ocean's surface. Shark Attacks. Many people are afraid of sharks, but most sharks do not attack humans. Great white sharks are one of the few kinds of sharks that are dangerous to people. Shark Hunting. Shark fishing boats. People hunt sharks for their skin, oil, and teeth. Many people eat shark meat, and shark fins are used to make soup. Many kinds of sharks are now in danger of being completely killed off. Sharks are an important part of the balance of life in the world's oceans. They have as much right to live as any other animal.Administrative jobs involve performing administrative roles that support workers in the agriculture industry. b. Engineering jobs involve using high-level science and math to solve complex problems. Professionals, evaluate, design, test and install agricultural equipment and systems. c. Labor jobs require workers to perform manual tasks such as planting, harvesting, caring for animals and maintaining equipment Sales jobs are performed by professionals who are responsible for selling materials and products to customers. e. Science jobs are those of scientists who work in agriculture and specialize in crops, livestock or food production. Agricultural Jobs: a. Farm workers perform essential manual labor tasks under the supervision of farmers and ranchers. They harvest or inspect crops, assist in watering the plants, applying fertilizer and pesticides to control weeds and insects. b. Growers are responsible for taking care and raising crops that involves proper management of the growing plants and its environment to keep the crops/plants healthy. c. Grain Elevator operators assist in maintaining essential quality standards of grains by properly storing, shipping and purchasing grains. They receive incoming grain deliveries, store the grain safely and they may assist in preparing outgoing shipments, drying grain and blending different grain types. d. Agricultural equipment technicians maintain, install and repair machines and implements. They perform preventive maintenance, which may involve refueling machines, replacing batteries, changing the oil and lubricating moving parts. When they detect a malfunctioning equipment, they perform diagnostic tests and conduct necessary repairs. e. Purchasing agents are responsible for buying agricultural products and raw materials at wholesale for processing and reuse. These professionals often have to meet specific purchasing quotas for processors. They work with several farming clients, who serve as suppliers of grain, milk and other agricultural products. f. Farm warehouse managers are responsible for overseeing all activities related to storing, shipping and receiving agricultural materials. They send and receive shipments, including loading and unloading products and materials Agriculture specialists perform administrative support and clerical tasks that focus on a certain aspect of farming. Some agriculture specialists focus on storage, which requires them to work with farmers to develop high-performing crop and grain storage and inventory systems. h. Sales representatives sell materials and products to businesses and government agencies. They seek out prospective customers by attending trade shows, reviewing customer lists and following leads from existing clients. They determine customers' needs, explain how their products meet clients' needs and create packages that meet customers' budgetary and timeline needs. i. Crop managers oversee the many steps in the crop production process. They supervise seed sourcing, planting processes and scheduling as well as fertilizing, irrigation and harvesting. j. Environmental engineers use science and engineering principles to design and apply solutions to problems that occur on agricultural sites. They assess environmental conditions—including testing soil and analyzing drainage capabilities—and develop improvements. k. Feed mill managers supervise the production and storage of animal feed. They are responsible for monitoring inventory levels, scheduling feed production and inspecting the quality of the grain. These professionals set and maintain quality standards, assess and improve operating procedures and track customer complaints. l. Research scientists who specialize in agriculture often work as food scientists, who research and develop processes for manufacturing, storing and packaging food. They are responsible for developing or improving products, but some specialize in detecting contaminants or administering government regulationsScience Exam Parts of the Atom: The atom consists of a nucleus at its center, containing protons (positively charged) and neutrons (neutral), while electrons (negatively charged) orbit in electron shells around the nucleus. Atomic Number: The atomic number of an element is the number of protons in its nucleus. It defines the element and determines its place on the periodic table. Properties of Metals: Metals have properties like conductivity, malleability (can be flattened into sheets), and ductility (can be drawn into wires). Elements, Compounds, and Mixtures: Elements consist of only one type of atom. Compounds are made of two or more different elements chemically bonded. Mixtures are combinations of substances that are physically mixed but not chemically bonded. Homogeneous and Heterogeneous Mixtures: Homogeneous mixtures have a uniform composition (e.g., saltwater), while heterogeneous mixtures have different phases (e.g., oil and water). Changes of State: Changes like melting, evaporation, and condensation are examples of physical changes of state. Chemical and Physical Properties: Chemical properties describe how a substance can change to form a new substance, while physical properties are characteristics like color, texture, and state (solid, liquid, gas). Physical and Chemical Change: A physical change involves the appearance or state of matter, but the substance remains the same. A chemical change involves the formation of new substances. Chemical Equations: Chemical reactions can be represented with chemical equations that show reactants (what you start with) and products (what is formed). Chemical Formulas: Chemical formulas represent the composition of compounds. For example, NaHCO3 is sodium bicarbonate, consisting of one sodium (Na), one hydrogen (H), one carbon (C), and three oxygen (O) atoms. Energy: Types of Energy: Energy can be kinetic (related to motion), potential (stored energy), thermal (heat energy), electrical, chemical, and more. Units of Energy: Common units of energy include joules (J) and calories (cal). Law of Conservation of Energy: Energy cannot be created or destroyed, only transferred or transformed from one form to another. Energy Transfer and Transformation: Energy moves from one object to another, changing forms along the way. Useful and Waste Energy: Useful energy is what can be harnessed and used for a specific purpose. Waste energy is energy that is not used and is often lost. Energy Flow Diagrams: These diagrams show how energy is transferred or transformed within a system. Energy Efficiency: Efficiency is a measure of how much useful energy is obtained from a system. It can be calculated using the equation: Efficiency = (Useful Energy Output / Total Energy Input) x 100%. Fossil Fuels and Renewable Energy: Fossil fuels, like coal, oil, and natural gas, are non-renewable sources of energy. Renewable energy sources include solar, wind, and hydroelectric power. Variables: Independent Variable: The variable that is manipulated or changed in an experiment. Dependent Variable: The variable that is measured or observed and is affected by changes in the independent variable. Controlled Variables: Factors that are kept constant to ensure a fair and accurate experiment.
