Historically, astronomy has focused on observations of heavenlybodies. It is a close cousin to astrophysics. Succinctly put,astrophysics involves the study of the physics of astronomy andconcentrates on the behavior, properties and motion of objects outthere. However, modern astronomy includes many elements of themotions and characteristics of these bodies, and the two terms areoften used interchangeably today.Unlike most other fields ofscience, astronomers are unable to observe a system entirely frombirth to death; the lifetime of worlds, stars, and galaxies spanmillions to billions of years. Instead, astronomers must rely onsnapshots of bodies in various stages of evolution to determine howthey formed, evolved and died. Thus, theoretical and observationalastronomy tend to blend together, as theoretical scientists use theinformation actually collected to create simulations, while theobservations serve to confirm the models — or to indicate the needfor tweaking them.

Diesel Engine 2.6 APK
KarenOn Inc
"Diesel engines may be designed as either two-stroke or four-strokecycles. They were originally used as a more efficient replacementfor stationary steam engines. Since the 1910s they have been usedin submarines and ships. Use in locomotives, trucks, heavyequipment and electricity generation plants followed later. In the1930s, they slowly began to be used in a few automobiles. Since the1970s, the use of diesel engines in larger on-road and off-roadvehicles in the US increased. According to the British Society ofMotor Manufacturing and Traders, the EU average for diesel carsaccounts for 50% of the total sold, including 70% in France and 38%in the UK.[3] The world's largest diesel engine put in service in2006 is currently a Wärtsilä-Sulzer RTA96-C Common Rail marinediesel, which produces a peak power output of 84.42 MW (113,210 hp)at 102 rpm.[4][5]"
Plant Identification 2.6 APK
KarenOn Inc
" Unlike a traditional plant identification key that provides youwith only two choices at each step (a dichotomous key), these keyslet you select multiple characters simultaneously (polyclave key).This makes more character data available in the key and minimizesthe number of steps it takes to identify a plant. These data setswere developed cooperatively by the collaborators cited in the keysand the USDA NRCS National Plant Data Team. The automated plantkeys run in SLIKS freeware written in JavaScript and let youidentify specific groups of plants known to occur in the U.S. Thisfreeware has limited functionality and is best view using InternetExplorer. The species list in the wetland monocot key is derivedfrom the U.S. Fish and Wildlife Service National Wetland InventoryNational List of Vascular Plant Species That Occur in Wetlands:1998 National List. Other keys are based on the species lists inPLANTS. These draft plant character data sets are for testingpurposes only. Data development for the grass and legume keys werepartially funded by the USDA NRCS Agricultural WildlifeConservation Center and the USDA NRCS Louisiana State Officecontributed to grass key development.

"No experience is necessary to begin Krav Maga. In the beginning,you will learn basic stances, striking, techniques for falling andgetting up safely, and basic defenses against common attacksincluding chokes and headlocks. In addition to learning how to dealwith an attack, you will train to perform better under stress andlearn awareness and prevention techniques that will help keep youfrom getting into problematic situations. After mastering thebasics, advanced students will train to deal with multiplesimultaneous attackers, weapons, complicated situations, and learnadvanced combative and weapon techniques (standing up or on theground). IMG_5022 For beginners, Krav Maga P1 classes are theperfect class to take for your first class in Krav Maga. We rotatethrough the material constantly and do not have a set rotation or aset “introductory class”. We find that most students cover andpractice all of the material sufficiently after about 4 months or35 classes to be ready for the P1-to-P2 test. We know it’ssometimes intense to join in on an ongoing class, but this is apart of the training. Self-defense means training under intense andunsettling circumstances. If you want to be able to react calmlyduring the unexpected, it’s critical that you train under stress.Join in, and do your best. All ages, shapes, and sizes can learnlife saving skills from Krav Maga training. For students comingfrom other martial arts: Since our material and purpose isdifferent from other martial arts, we ask that you begin in P1classes until you have received instructor approval to advance. WhyTactica and the Krav Maga Institute? At KMI, we believe inproviding the best in self-defense training, focusing on realisticscenarios with high-quality instruction and attention. Our classesare serious, but ego-free, safe, and fun. Tactica’s Krav MagaInstitute is your best source of authentic Israeli Krav Maga. Allof our instructors are trained, certified, and professional, withextensive experience."
Computer Engineering 2.6 APK
KarenOn Inc
"This course presents the fundamentals of object-oriented softwaredesign and development, computational methods and sensing forengineering, and scientific and managerial applications. It covertopics, including design of classes, inheritance, graphical userinterfaces, numerical methods, streams, threads, sensors, and datastructures. Students use Java® programming language to completeweekly software assignments. How is 1.00 different from other introprogramming courses offered at MIT? 1.00 is a first course inprogramming. It assumes no prior experience, and it focuses on theuse of computation to solve problems in engineering, science andmanagement. The audience for 1.00 is non-computer science majors.1.00 does not focus on writing compilers or parsers or computingtools where the computer is the system; it focuses on engineeringproblems where the computer is part of the system, or is used tomodel a physical or logical system. 1.00 teaches the Javaprogramming language, and it focuses on the design and developmentof object-oriented software for technical problems. 1.00 is taughtin an active learning style. Lecture segments alternating withlaboratory exercises are used in every class to allow students toput concepts into practice immediately; this teaching stylegenerates questions and feedback, and allows the teaching staff andstudents to interact when concepts are first introduced to ensurethat core ideas are understood. Like many MIT classes, 1.00 hasweekly assignments, which are programs based on actual engineering,science or management applications. The weekly assignments build onthe class material from the previous week, and require students toput the concepts taught in the small in-class labs into a largerprogram that uses multiple elements of Java together."
Video Editing 2.6 APK

"Video editing is the process of editing segments of motion videoproduction footage, special effects and sound recordings in thepost-production process. Motion picture film editing is apredecessor to video editing and, in several ways, video editingsimulates motion picture film editing, in theory and the use oflinear video editing and video editing software on non-linearediting systems (NLE). Using video, a director can communicatenon-fictional and fictional events. The goals of editing is tomanipulate these events to bring the communication closer to theoriginal goal or target. It is a visual art.[2] Early 1950s videotape recorders (VTR) were so expensive, and the quality degradationcaused by copying was so great, that 2 inch Quadruplex videotapewas edited by visualizing the recorded track with ferrofluid andcutting with a razor blade or guillotine cutter and splicing withvideo tape. The two pieces of tape to be joined were painted with asolution of extremely fine iron filings suspended in carbontetrachloride, a toxic and carcinogenic compound. This""developed"" the magnetic tracks, making them visible when viewedthrough a microscope so that they could be aligned in a splicerdesigned for this task. Improvements in quality and economy, andthe invention of the flying erase-head, allowed new video and audiomaterial to be recorded over the material already recorded on anexisting magnetic tape and was introduced into the linear editingtechnique. If a scene closer to the beginning of the video tapeneeded to be changed in length, all later scenes would need to berecorded onto the video tape again in sequence. In addition,sources could be played back simultaneously through a vision mixer(video switcher) to create more complex transitions between scenes.A popular 1970-80s system for doing that was the U-matic equipment(named for the U-shaped tape path). That system used two tapeplayers and one tape recorder, and edits were done by automaticallyhaving the machines back up, then speed up together in synchrony,so the edit didn't roll or glitch. Later, 1980-90's came thesmaller beta equipment (named for the B-shaped tape path), and morecomplex controllers, some of which did the synchronizingelectronically."
Shotokan Karate 2.6 APK

"A most important technique, so we are going to explain some vitaltheoretical points, using it as an example. First of all, there aredifferent ideas in different schools, about the way your bodyshould move to help the punch to be fast and strong. In theKyokushin we end up with the shoulders turned 45 degrees, so thatthe twist of the body increases the speed of the hand. But it onlyworks if the two motions are performed in synch. If you, forexample, move your shoulders, and then begin to move the hand, youropponent will get a message: ""his shoulders are moving, looks likea punch, I better do something"". In many places of this book I amgoing to talk about the ways to NOT to communicate your intentionsto your opponent. If you turn your shoulders more then 45 degrees,you will a) injure your back sooner or later, b) spend too muchenergy, c) loose the speed, and d) make your back vulnerable to thecounterattack. The hips are turning too, it looks more like a slap,throwing an impulse, to provide an additional speed. It isdifferent from many other karate schools. Also keep in mind, thatif you work on a very short distance, there will be no space forhips and shoulders to perform the ""classics"". The techniques (allof them) are adjustable. The fist must be properly closed. The handshould be almost relaxed, until the last moment, when it istouching the target. Then it should be completely tense, all yourfocus on the target, or - if you are performing a ""breaking""punch - behind the target. You will often hear the saying, that ifyou are hitting the chest, you should aim the backbone. The outerside of the palm and the wrist must be on a straight line. Imaginethe line that goes through the seiken (nockles of the pointing andthe middle fingers), the wrist and the elbow. This should be theline and not a zigzag. Otherwise you will bend your wrist, usingall the power of your hand, hips, plus the body weight. The fistbegins its motion from the place almost under the armpit, at theheight of the nipple. This is different from many traditionalschools, they start from the hip level. The fist rotates. At thebeginning it is with the palm up, at the end - with the palm down.It should screw itself into the target - it will help your elbow tounbend, and the energy of a punch will increase. But the elbowshould not unbend completely - it must be slightly bent, to prewentthe injury. Imagine, that your elbow is straight, and your opponentblocks it, or hits it. Very bad for you. While if the elbow is bent- it is not that easy to damage, and your opponent will thinktwice, before hitting it. Your elbows must look down. If they looksideways, your punch will be less powerful, and your armpits areopened for an attack. The other hand is performing a ""reverse"" -exactly the same move, in the opposite direction. At the end, itwill be near the armpit, ready to launch another punch. In themiddle of the trajectory, both hands should face each other, palmsinside. This is often used to check the beginners for mistakes. Thefist should move by the straight line. It does not matter, that thebody is turning, and hands are moving, and hips are moving too. Ityour hand is moving by the ""freehand trajectory"" - you are doingsomething wrong. The line between your fist, when still in thearmpit, and the target, is the trajectory to follow. "
World Clock 2.6 APK
KarenOn Inc
"A world clock is a clock which displays the time for variouscities around the world. The display can take various forms: Theclock face can incorporate multiple round analogue clocks withmoving hands or multiple digital clocks with numeric readouts, witheach clock being labelled with the name of a major city or timezone in the world. It could also be a picture map of the world withembedded analog or digital time-displays. A moving circular map ofthe world, rotating inside a stationary 24-hour dial ring.Alternatively, the disc can be stationary and the ring moving.Light projection onto a map representing daytime, used in theGeochron, a brand of a particular form of world clock. There arealso worldtime watches, both wrist watches and pocket watches.Sometime manufacturers of timekeepers erroneously apply theworldtime label to instruments that merely indicate time for two ora few time zones, but the term should be used only for timepiecesthat indicate time for all major time zones of the globe."
Human Anatomy 2.6 APK

"Cells The body contains trillions of cells, the fundamental unitof life.[4] At maturity, there are roughly 30[5]–37[6] trillioncells in the body, an estimate arrived at by totalling the cellnumbers of all the organs of the body and cell types. The body isalso host to about the same number of non-human cells[5] as well asmulticellular organisms which reside in the gastrointestinal tractand on the skin.[7] Not all parts of the body are made from cells.Cells sit in an extracellular matrix that consists of proteins suchas collagen, surrounded by extracellular fluids. Of the 70 kgweight of an average human body, nearly 25 kg is non-human cells ornon-cellular material such as bone and connective tissue.[5] Cellsin the body function because of DNA. DNA sits within the nucleus ofa cell. Here, parts of DNA are copied and sent to the body of thecell via RNA.[8] The RNA is then used to create proteins which formthe basis for cells, their activity, and their products. Proteinsdictate cell function and gene expression, a cell is able toself-regulate by the amount of proteins produced.[9] However, notall cells have DNA – some cells such as mature red blood cells losetheir nucleus as they mature. Tissues The body consists of manydifferent types of tissue, defined as cells that act with aspecialised function.[10] The study of tissues is called histologyand often occurs with a microscope. The body consists of four maintypes of tissues – lining cells (epithelia), connective tissue,nervous tissue and muscle tissue.[11] Cells that lie on surfacesexposed to the outside world or gastrointestinal tract (epithelia)or internal cavities (endothelium) come in numerous shapes andforms – from single layers of flat cells, to cells with smallbeating hair-like cilia in the lungs, to column-like cells thatline the stomach. Endothelial cells are cells that line internalcavities including blood vessels and glands. Lining cells regulatewhat can and can't pass through them, protect internal structures,and function as sensory surfaces.[11]"
