Learning how to make paper airplanes is not such a difficult task.It is a hobby that has been loved by generations of kids forcenturies. If you want to create a paper airplane that soars highand far, take a moment to check out the following tips andguidance.First of all you will need to understand there is a bigdifference between folding a piece of paper a few times to make aplane, and making the effort to create a craft that flies to theheavens. It is important that you use the right kind of paper, thisneeds to be strong and sturdy as opposed to flimsy and easy tocrumple.To get the aerodynamics right, you will need to work on ahard dry surface, for example a kitchen or dining room table. Thefolds need to be both precise and sharp without causing damage tothe rest of the paper. Be aware that if there is any kink in afold, the plane is not going to fly straight or far.If you aredetermined to create a paper plane that flies higher and furtherthan that of your friends, it can be useful to make pencil lines onthe paper prior to folding. It is surprising the difference havinggeometrically precise folds can make on the plane's aerodynamics.Itcan take a few attempts to create a successful paper airplane. Donot get disheartened if on the first few tries your plane goes nosedown into the ground after barely a meter. When this happens, alterthe dimensions until you have made the perfect design. Try not tore-do the same sheet of paper, always start afresh when possible.Toensure that your folds are razor sharp, use a ruler to press andcrease. Also, by having a ruler on hand, you can take measurementsto make sure each wing has exactly the same dimensions. A plastictransparent ruler would be better than a solid metal design, as youcan see exactly what you are doing.Though you can get various paperplane blueprints from craft books and websites, you may find itmore fun if you simply experiment with your own concepts. Ofcourse, there is nothing wrong with doing a little research onlineas to the most desirable wing shapes and paper sizes, but do not beafraid to create your own designs. A few extra folds and cuts canallow you to put together an amazing paper airplane. Besides, paperis an easily available and cheap commodity, experimenting will notcost you a fortune.Apart from choosing the right type of design,why not also experiment with different paper colors. The color willnot impact on performance, but it can make your plane stand outfrom the crowd.Learning how to make paper airplanes is a greatactivity, and one that can help to strengthen a bond between aparent and a child. It is a harmless craft that can provide hoursof cheap entertainment.

Biology 10th Class 1.0 APK
Biology, a branch of science, is the study of life and itsprocesses. It studies living things in all their aspects and forms.Biology covers a vast area, so, it has been divided into many subdivisions such as botany, algology, zoology, cytology, mycology andmicrobiology. All its branches have contributed to humanity in manyways such as improvements in agriculture, study of diseases etc.Bystudying biology, students understand that life is all aboutinteractions such as cells interact with their environment and witheach other and so do ecosystems, organs and organisms.Why StudyBiology?Here are some reasons to study biology:• The study ofBiology increases the understanding of the human body.• It educatesa student about all living beings, which helps in making theenvironment better for the future.• With the knowledge of Biologyone can understand the world and its natural processes in a betterway.• It teaches how different organs and systems work which helpsin understanding how everything is connected in the body.Study Tipsfor Biology• To learn Biology, it is very important to learn itsterminology. Biology can be tough if you don't know all the terms.Whenever you don't understand a word, make a note of it and lookfor the definition.• Read Biology books and if you find them toughto comprehend you can also look for online biology help resources.Though reading by book is the best way to learn.• Pay attention tothe pictures. If you will understand a picture, the explanationgiven with it may also become very easy. So, don't just ignore apicture thinking that it will only add some more minutes to yourstudy time.• After completing a topic, solve all questions, thiswill increase your understanding of the topic.• Don't study as ifyou have to just score the marks, be curious and interested tolearn the topic.• Still if you find the subject hard, there aremany online biology tutoring sites, so take the help of anonlinebiology tutor to understand the topics which you find hard.•Before attending the lab class, study what your class is going tobe all about. This way you will be able to complete the labassignment successfully. Attend all your lab classes, they play avital role in learning Biology.• Take the notes when your tutor isteaching in the class, this will help you in recalling all theclassroom study.What would you do if you woke up one morning andbirds were no longer chirping beyond your windowsill? That can be adifficult question to answer, because so many of us have neverthought of that possibility. When we awake in the morning, maybewe'll hear a bird or two chirping, maybe we won't. But when we do,we can't help but pay attention to their songs of joy. Granted, ifyou're not an "early bird" per se, you may not be as fond of theirchirps as I am. I live out in the country, so I get to appreciatethem every morning. But maybe you live in the city, and aren't asfortunate to be surrounded by our beautiful wildlife. So thethought that they could one day disappear, may have never crossedyour mind.Not only are our feathered friends becoming more and moreendangered, but nature and wildlife in general are all at risk.More frequently, one species or another are becoming either extinctor endangered, and nature itself is becoming less natural. But,instead of discussing the ways in which we can reduce our carbonfootprints and help preserve nature- recycle, reduce energy, joinan organization, etc.- I'm going to let you in on some fun (andcheap) things that you can do alone, or with family and friends, toenjoy and appreciate nature more.
Protein Biochemistry Definition 1.0 APK
Proteins are the most versatile macromolecules in living systemsand serve crucial functions in essentially all biologicalprocesses. They function as catalysts, they transport and storeother molecules such as oxygen, they provide mechanical support andimmune protection, they generate movement, they transmit nerveimpulses, and they control growth and differentiation. Indeed, muchof this text will focus on understanding what proteins do and howthey perform these functions.Several key properties enable proteinsto participate in such a wide range of functions. Proteins arelinear polymers built of monomer units called amino acids. Theconstruction of a vast array of macromolecules from a limitednumber of monomer building blocks is a recurring theme inbiochemistry. Does protein function depend on the linear sequenceof amino acids? The function of a protein is directly dependent onits threedimensional structure (Figure 3.1). Remarkably, proteinsspontaneously fold up into three-dimensional structures that aredetermined by the sequence of amino acids in the protein polymer.Thus, proteins are the embodiment of the transition from theone-dimensional world of sequences to the three-dimensional worldof molecules capable of diverse activities. Proteins contain a widerange of functional groups. These functional groups includealcohols, thiols, thioethers, carboxylic acids, carboxamides, and avariety of basic groups. When combined in various sequences, thisarray of functional groups accounts for the broad spectrum ofprotein function. For instance, the chemical reactivity associatedwith these groups is essential to the function of enzymes, theproteins that catalyze specific chemical reactions in biologicalsystems (see Chapters 8–10). Proteins can interact with one anotherand with other biological macromolecules to form complexassemblies. The proteins within these assemblies can actsynergistically to generate capabilities not afforded by theindividual component proteins. These assemblies includemacro-molecular machines that carry out the accurate replication ofDNA, the transmission of signals within cells, and many otheressential processes. Some proteins are quite rigid, whereas othersdisplay limited flexibility. Rigid units can function as structuralelements in the cytoskeleton (the internal scaffolding withincells) or in connective tissue. Parts of proteins with limitedflexibility may act as hinges, springs, and levers that are crucialto protein function, to the assembly of proteins with one anotherand with other molecules into complex units, and to thetransmission of information within and between cells.Macromoleculesconsisting of long sequences of α-amino acids [H2N-CHR-COOH] inpeptide (amide) linkage (elimination of H2O between the α-NH2 andα-COOH of successive residues). Protein is three fourths of the dryweight of most cell matter and is involved in structures, hormones,enzymes, muscle contraction, immunologic response, and essentiallife functions. The amino acids involved are generally the 20α-amino acids (for example, glycine, l-alanine) recognized by thegenetic code. Crosslinks yielding globular forms of protein areoften effected through the -SH groups of two l-cysteinyl residues,as well as by noncovalent forces (hydrogen bonds, lipophilicattractions, etc.).[G. prōtos, first, + -in]
Master Coil Vaporizer 1.0 APK
An atomizer is defined as any device that creates mist out ofliquid. More recently it has become a term closely associated withvaping. It sounds complicated, but it is essentially just a heatingcoil made from a piece of resistance wire that heats up in order tocreate vapor out of e-liquid.These atomizers, also referred to asvape coils, come in a variety of styles ranging from disposablecoil heads to the do-it-yourself coil builds. Atomizers – morespecifically the coils –are measured in ohms, based on the amountof resistance they have. The lower the ohms, the more power theywill demand.The word atomizer is used in a variety of ways, whichcan create some confusion. It can either refer the vape coil itselfor the device containing it – like a sub ohm tank or RDA, which arecommonly used for vaping.Vape coils can be made out of varioustypes of wire including kanthal, stainless steel, nickel andtitanium. Atomizers requires a wicking material that feeds e-liquidto your vape coils. When you engage the vaporizer battery, the coilwill heat up and turn the e-juice into warm, tasty vapor.Someatomizers are actually made of materials such as ceramic. Otheralternatives used for wicking vape coils include stainless steelmesh, silica or ekowool. Now let’s take a look at the two maincategories of atomizers to find out which one suits your exactvaping needs.Building your own vape coils isn’t very hard, butfortunately it’s not a requirement to vape. Many great devicesstill use pre-made coils. These atomizers, often referred to ascoil heads, are specifically designed for your particular deviceand are good for about an entire week of usage.Each atomizer israted at a different resistance and has an optimal wattage range.Sometimes a tank can have a wide range of coil heads available,which can be very confusing to re-order.For example the KangerToptank has nearly a dozen varieties of coil heads available forit.Some coils are geared towards high-wattage vaping, somelow-wattage vaping and others are made to be used with temperaturecontrol mode. Specific vape coils can have an effect on the type ofdraw you get. Some are designed for direct lung vaping, whileothers for mouth-to-lung.If you’re somebody who likes to vape atlower wattages, we recommend using a vape coil with a higherresistance, meaning more ohms. Lower resistance coils require morepower, but are also capable of producing more vapor. A sub ohm vapecoil has a resistance lower than 1.0 ohm.Rebuildable atomizersrequire you to build your own vape coils for them. This can be alittle bit tricky, and isn’t recommended for beginner vapers.However, once you get into rebuildable vape coils, thepossibilities are endless. You can create the perfect coil tailoredto your specifications.Building your own vape coils puts you atanother advantage, which is that you can re-wick them. This is whenyou take the cotton, or whichever wicking material you use, andreplace it with a fresh piece. You can also clean your coils offand get rid of any taste that may still be lingering.By now youshould know what an atomizer is and have a basic understanding ofhow it works. You don’t need to be a master coil builder overnight,making super advanced vape coils isn’t everyone’s calling. It’sgreat to know you can get a satisfying vape from a disposable coilhead.The word atomizer has been slapped around and abused so much,even expert vapers aren’t quite sure of its proper usage. One thingfor sure is that an atomizer is a device that creates vapor,whether it be a dripper or a tank, and vape coils are the elementsthat heat up inside.Coils have various resistances for differentuses, allowing a vaper to tailor their vaping experience to theirneeds. Sub ohm coils are often used at higher temperatures,producing warmer and larger amounts of vapour. Conversely, higherresistance coils do not allow as much current to flow, creatingless heat and a cooler vape.
Enzyme Biochemistry 1.0 APK
An enzyme is defined as a macromolecule that catalyzes abiochemical reaction. In this type of chemical reaction, thestarting molecules are called substrates. The enzyme interacts witha substrate, converting it into a new product. Most enzymes arenamed by combining the name of the substrate with the -ase suffix(e.g., protease, urease). Nearly all metabolic reactions inside thebody rely on enzymes in order to make the reactions proceed quicklyenough to be useful.Chemicals called activators can enhance enzymeactivity, while inhibitors decrease enzyme activity. The study ofenzymes is termed enzymology.There are six broad categories used toclassify enzymes: oxidoreductases - involved in electron transferhydrolases - cleave the substrate by hydrolysis (uptaking a watermolecule) isomerases - transfer a group in a molecule to form anisomer ligases (or synthetases) - couple the breakdown of apyrophosphate bond in a nucleotide to the formation of new chemicalbonds oxidoreductases - act in electron transfer transferases -transfer a chemical group from one molecule to anotherHow EnzymesWorkEnzymes work by lowering the activation energy needed to make achemical reaction occur. Like other catalysts, enzymes change theequilibrium of a reaction, but they aren't consumed in the process.While most catalysts can act on a number of different types ofreactions, a key feature of an enzyme is that it is specific.Inother words, an enzyme that catalyzes one reaction won't have anyeffect on a different reaction.Most enzymes are globular proteinsthat are much larger than the substrate with which they interact.They range in size from 62 amino acids to more than 2,500 aminoacid residues, but only a portion of their structure is involved incatalysis.The enzyme has what is called an active site, whichcontains one or more binding sites that orient the substrate in thecorrect configuration and also a catalytic site, which is the partof the molecule that lowers activation energy. The remainder of anenzyme's structure acts primarily to present the active site to thesubstrate in the best way. There may also be allosteric site, wherean activator or inhibitor can bind to cause a conformation changethat affects the enzyme activity.Some enzymes require an additionalchemical, called a cofactor, for catalysis to occur. The cofactorcould be a metal ion or an organic molecule, such as a vitamin.Cofactors may bind loosely or tightly to enzymes. Tightly-boundcofactors are called prosthetic groups.Two explanations of howenzymes interact with substrates are the "lock and key" model,proposed by Emil Fischer in 1894, and the induced fit model, whichis a modification of the lock and key model that was proposed byDaniel Koshland in 1958. In the lock and key model, the enzyme andthe substrate have three-dimensional shapes that fit each other.The induced fit model proposes enzyme molecules can change theirshape, depending on the interaction with the substrate.In thismodel, the enzyme and sometimes the substrate change shape as theyinteract until the active site is fully bound.
Coil Pots Ideas 1.0 APK
Even those who are new to clay should me able to make large andintriguing pottery using the coiling method. It is an extremelyversatile technique and coil pots are capable of the greatestcraftsmanship and artistry.The clay used to build coil pots needsto be matched to the final form, meaning larger structures willneed more strength. Their walls should be thicker, so choose a claybody for strength and also for a lower coefficient ofexpansion.Clay bodies that have sand or grog in them tend to workbest. Look for a shrinkage rate of 8% or lower. The clay shouldalso be soft in consistency. Stiff clay won't weld together aswell, which results in weaker joints that can crack apart. Clayshould also be thoroughly wedged before you use it. This willhomogenize it and remove air pockets which can cause blow outs inthe kiln.The floor or bottom of a coiled pot is usually a slab orpatty of clay the same thickness the finished pot will be. Thebottom slab should be substantially larger than the piece'sdiameter will be since it will be trimmed down later.Once the slabis made, it should be placed on a support surface that will allowthe piece to be moved safely. For a flat-bottomed pot, this supportsurface could be a bat or a disc of bisqued clay. For a pot with acurved bottom, a puki, a bowl-shaped mold made of plaster, wood, orbisqueware, is used.If a puki isn't available, a regular bowl ofthe right size and slope can be used. However, it must be linedwith several layers of newspaper or cloth before the clay slab isplaced into it.In sculptural terms, coiling is an additive processas the pot is created by adding material to it. Generally speaking,potters do use coils of clay, but additions can actually be madeusing other shapes, such as small patties.Working the piece on aturn table, banding wheel, or kickwheel can make the coilingprocess much faster and easier.Coiling begins on the upper surfaceof the pot's floor, not at the sides. Doing it this way results ina much stronger joint. Once the first coiled row is in place, theexcess slab is trimmed off and the outer edge of the slab is weldedupward into the coil.Soft clay can be directly welded row-into-row.The strongest joints are welded on both the interior and exteriorof the wall. Generally speaking, the thumb will be used on theinner surface moving downward, with the fingers on the outersurface welding upwards. If the clay has stiffened at all, scoreeach surface to be joined, brush on slurry or slip, then lay therow and weld.When coils are welded, the wall will thin and expandoutward. The more aggressive the welding, the more the walls willthin and expand. Because of this, coils may need to be madesubstantially thicker than the final wall will be. As a generalguideline, smaller pots will use coils 3/8 to 1 inch in diameter,and large pots will use coils 3/4 to 1-1/2 inch in diameter.Coiledforms can take more time to create than we have available in onesitting. When you have to leave your work while it is in progress,place damp paper towels across the top row. Cover the entire piecewith plastic.If you want the bottom of the pot to stiffen slightly,leave some gaps where the plastic meets the table or shelf.Otherwise, tuck the plastic under the support surface. If thehumidity is high, add a layer of newspaper or cloth in between thepot and the plastic. This will absorb any condensation, which couldotherwise make your pot collapse.

Learn Organic Chemistry 1.0 APK
Study of organic chemistry has gained a very high importance due toits relevance for many career oriented fields. Any field relatedwith medicine requires its in depth knowledge. In fact any careerin the Chemical Industry would be a non-starter without a thoroughknowledge of Organic Chemistry.A number of students take up OrganicChemistry (Orgo Chem) courses in their exuberance. However the rateof dropouts in the very first semester itself is very high - nearly60-70 percent. The primary reasons for the poor grades is thatstudents often try to cram the lessons instead of trying to gain agood understanding of the topics. Since Orgo Chem has a vast scope,it is impossible to memorize it and hence cramming becomes selfdefeating after some time.In my experience of over 20 yearsteaching Orgo Chem, I have realized that org-chem is very simple tounderstand if we go about it in a systematic manner. The focus inlearning Orgo Chem should be on understanding the topics andcementing the knowledge gained by relating it to a number ofexamples. Some of the aspects which can help the students gain agood command over the subject are as follows:Gain A GoodUnderstanding Of The Important Concepts Of General Chemistry CourseThis will help you lay a solid foundation for the OrganicChemistry. These are as follows:Periodic table and importantperiodic trends e.g electro negativity and electron affinity.LewisDot Structure, VSEPR Structures and calculations of formalcharges.Resonance and Hybrid structures.Acid - Base properties andfactors affecting the acidity / basicity of the molecules likeoxidation number, electronegativity and atomicsize.Hybridization.Basic concepts of chemical equilbrium and thermochemistry.Achieve Full Understanding Of Structures, Names AndShapes Of The Organic Molecules. If you wish to master Orgo Chemyou must master the naming and drawing out structures of theorganic molecules. Let me assure you that the IUPAC System ofnomenclature is very systematic and you only need to practice therules for naming and drawing structures of the compounds. If nameof the compound is given and by applying the rules the structurecan be easily drawn. To take an example, in case of 2-Butanol, Butsignifies a 4 Carbon chain, ol signifies alcohol (-OH) group and 2indicates that OH group is present on the second carbon. Hence thestructure will appear like this:CH3 - CH(OH) - CH2 - CH3It is assimple as that. Believe me, a lot of students would get stuck atthis step itself if they did not try to understand the logic butinstead tried to memorize the structure. Naming of compounds ormaking their structures from a given name can be played as ainteresting game with friends.There are however a few compounds forwhich the IUPAC nomenclature is not followed and these compoundsare popularly known with their common names e.g aniline is actuallyaminobenzene, tert-butyl alcohol is 1,1-dimethylethanol and vinylchloride is 1-chloroethene. Do not get worried as there are only10-15 of these exceptions of names and structures which you need topracticeUnderstanding The Concepts Of Organic Chemistry.Orgo Chemconcepts are the building blocks which are used again and again inreasoning and explanations of the mechanisms. There are just about20 important basic concepts on which you can build up the completemechanisms and reasoning. For example, in most of the mechanisms,H+ acts as catalyst and protonates the atom containing lone pair.
