When describing adventitious sounds, the timing of these sounds in the respiratory cycle should be noted (e.g. Continuous sounds include ronchi and wheezes. Discontinuous adventitious breath sounds include crackles (also called rales). It is important to know where these sounds are normally heard as hearing certain sounds in locations where they are not normally found may signify pathology.Ĭlick on the interactive icon for specific descriptions of these sounds, and for practice listening to these sounds.Ībnormal or adventitious breath sounds may indicate the presence of pathology and are generally divided into two categories: discontinuous and continuous sounds. Normal breath sounds include vesicular, bronchial and bronchovesicular breath sounds. Normal breath sounds are generally softer at the apices and become louder at the bases. Note these characteristics as you listen in different areas. ![]() Normal breath sounds differ over various portions of the lungs with regard to intensity, pitch, and relative duration of inspiratory and expiratory phases. ![]() Lung sounds are absent over a pneumothorax.Lung sounds may be diminished due to shallow breathing or hyperinflation, pleural disease, mucous plugging or obesity.Lung sounds may be louder in areas where lung tissue is more dense.Note the inspiratory to expiratory ratio.When abnormalities are found, listening to several breaths in that location may be necessary.

This means that our gauge wire needs to be big enough to safely handle these two measurements. If you look at the Inergy Linx 100 Watt Flexible Solar Panel, available from Shop Solar Kits, you will see that the voltage at maximum power (Vm) is 17.6V, and the current at maximum power (Im) is 5.68A. These variables include the voltage of the system, the maximum amperage that will be produced by your solar panel, and the distance between the batteries and the solar panels, or between the batteries and charge controller.ĭifferent wire gauges can only handle a certain amount of voltage and amperage, which is why it is important to look at the specifications of your solar panel as your starting point. Three main variables need to be considered when calculating the wire gauge required for your solar array. Variables and Parameters to Focus on When Calculating Wire Gauge This is more tedious, but we will go through this method too, in case it is your preferred option.ĭespite the option used to calculate wire gauge, the same variable will be used in both.īelow we will take you through what those variables are. All you need to do is input certain variables, that we will speak about shortly, into a calculator and it provides an estimate almost instantaneously.Īnother way to calculate wire gauge is through a manual equation. The easiest way to calculate it is by using an online calculator made specifically for wire gauge estimation. There are various different ways that you can calculate what wire gauge you will need for your 100-watt solar panel. You will have to look at your 100-watt solar panel specifications, figure out what size battery for a 100 watt solar panel, and look at the requirements of your array as a whole to do so. The wire gauge needs to be calculated in accordance with your solar array. When calculating wire gauge, there is not necessarily a “one size fits all” for 100-watt solar panels. How to Calculate the Wire Gauge Needed for a 100-Watt Solar Panel In this article, we will be discussing how to calculate what size wire gauge you need for your specific solar array, the reason why the wire size is so important, as well as what gauge of wire is most appropriate for a 100-watt solar panel. It may seem like “just a little wire”, but correctly sized wires are imperative for not only the performance of your solar array but for your own safety, too. You might not think so, but the gauge of the wires you use for your solar panel array plays a crucial role in the running of your solar system. ![]()
The fitness of the prey population-the number of individuals in the population, chance of being able to reproduce, and chance of survival-is controlled by the predator population. A prey species can also use the aforementioned attributes listed for the predator to avoid being caught and killed. Likewise, the prey has strategies to help it avoid being killed by a predator. The predator may use speed stealth (the ability to approach unnoticed by being quiet and deliberate in its movements, or by approaching from upwind) camouflage a highly developed sense of smell, sight, or hearing tolerance to poison produced by the prey production of its own prey-killing poison or an anatomy that permits the prey to be eaten or digested. A species that has become a successful predator and has survived has developed a few or a number of strategies to acquire the prey. For example, fossils dating back nearly 400 million years have revealed evidence that extinct animals known as Hederellids were the prey of an as yet unknown creature that killed them by drilling holes through their tubular shells.Īs species developed and flourished, other species exploited them as their food. Predators and prey have evolved together, and their relationship is ancient. Historical Background and Scientific Foundations The key aspect of a predator-prey relationship is the direct effect that the predation has on numbers of their prey. In contrast, fish and seals that are the prey of some species of shark are examples of prey that is fed on while still alive. For example, a cheetah will stalk, run down, and kill its prey (examples include the gazelle, wildebeest, springbok, impala, and zebra). In many higher organisms, the prey can be killed by the predator prior to feeding. Over time, the two populations cycle up and down in number. If the rabbit population is over-exploited or drops due to disease or some other calamity, the predator population will soon decline. When the numbers of a prey such as rabbits explode, the abundance at this level of the food chain supports higher numbers of predator populations such as foxes. Predator and prey populations respond dynamically to one another. ![]() Indeed, the study of Bdellovibrio predation has revealed a great deal of the mechanics of predation and how the predator and prey populations fluctuate in number over time in a related fashion. The bacteria Bdellovibrio feed on other bacteria that are bioluminescent (they produce internal light due to a chemical reaction). ![]() Predators and prey exist among even the simplest life forms on Earth, single-celled organisms called bacteria. Bears, for example, feed on berries, a rabbit feeds on lettuce, and a grasshopper feeds on leaves. A few of them are the lion-zebra, bear-salmon, and fox-rabbit. There are literally hundreds of examples of predator-prey relations. The organism that feeds is called the predator and the organism that is fed upon is the prey. As you can see, there does appear to be cycling over time in both hare and lynx number, but it's not as clean as in the simple mathematical models.Predator-prey relations refer to the interactions between two species where one species is the hunted food source for the other. While this is an indirect measure of predation, the assumption is that there is a direct relationship between the number of pelts collected and the numer of hare and lynx in the wild. One of the classic studies of predator-prey interactions is the 90-year data set of snowshoe hare and lynx pelts purchased by the Hudson's Bay Company of Canada. ![]() Part 3: Exploitation and population cycles Watch these short video lectures for a very nice overview of predator-prey interactions. What causes prey number to cycle in the absence of predators? Generally the answer is that without predators to suppress their number, prey outstrip available food resources, nesting sites, or some other limited resource and thus begin to suppress their further growth through competition. Interestingly though, there are situations where predators are absent, such as on islands or in other isolated areas where they either never became introduced or where they have died out, and yet prey continue to oscillate in number. As long as predator and prey numbers don't drop to zero, this cycle can repeat indefinitely. This can lead to cyclical patterns of predator and prey abundance, where prey increase in number and then, with abundant food, predator number increases until the predators begin to suppress prey numbers and then decrease as well. What may require a bit more reflection is that prey, in turn, affect the number of predators because, when prey become scarce, predators may die of starvation or fail to reproduce. It should come as no surprise that predators influence the numbers of their prey. ![]() ![]() Plugs of both sleeve sizes are usually 9.5mm long, but longer and shorter ones do exist. Many devices will have a small diagram indicating the polarity expected by the device care should be taken to adhere to this, as an improper power supply may damage the device. Polarity is the final aspect to consider most often, the sleeve will be considered 0V and the tip will be a positive voltage relative to the sleeve. 3.5mm sleeve plugs usually mate to a jack with a 1.3mm pin. Unfortunately, this means that a plug designed for a 2.5mm pin will fit in a 2.1mm jack, but that the connection will be, at best, intermittent. Pin diameter is contingent upon sleeve diameter a 5.5mm sleeve will have either a 2.5mm or 2.1mm pin. Sleeve diameter is most commonly either 5.5mm or 3.5mm. When ordering, there are three differentiating characteristics of a barrel connection- inner diameter (the diameter of the pin inside the jack), outer diameter (the diameter of the sleeve on the outside of the plug), and polarity (whether the sleeve voltage is higher or lower than the tip voltage). Make sure to check out the product image and specs to find what you are looking for!īarrel connectors provide only two connections, frequently referred to as "pin" or "tip" and "sleeve". ![]() Depending on where your get these connectors, the jack can be referred to "male" barrel connector due to the pin in the center and vice versa for the plug. Heads up! There are varying opinions on the gender of the jack and plug for these low power coax connectors. Some of these connectors will have an additional contact that allows the application to detect whether a power supply is plugged into the barrel jack or not, thus allowing the device to bypass batteries and save battery life when running on external power. The female barrel connector, or "jack", can be purchased in several varieties: PCB mounted (surface mount or through hole), cable mount, or panel mount. Wall adaptors are widely available, in a variety of power ratings and voltages, making barrel connectors a common means for connecting power to small projects. Barrel Connectorsīarrel connectors are typically found on low-cost consumer electronics which can be plugged into wall power via bulky AC wall adaptors. These vary widely by application and size, but we will only focus on some of the most common ones here. While many connectors carry power in addition to data, some connectors are used specifically to provide power connections to devices. Pin 11 can be used for activity indication and/or staggered spin-up. If pulled down at the connector (as it is on most cable-style SATA power connectors), the drive spins up as soon as power is applied.Share on Twitter Share on Facebook Pin It Power Connectors (3.3 V Power, Pre-charge prior to SATA 3.3) The same physical connections are used on 3.5-inch and 2.5-inch notebook hard disks. One pin from each of the three voltages is also used for hotplugging. This is because the small pins cannot supply sufficient current for some devices. The seemingly large number of pins are used to supply three different voltages - 3.3 V, 5 V, and 12 V.Įach voltage is supplied by three pins ganged together (and 5 pins for ground). The SATA standard specifies a power connector sharply differing from those used by PATA drives and many other computer components.

![]() Notice that id information was added to the p tag in our body. The #ourParagraph section tells it to only style elements with the id ourParagraph. The p in the style tag is telling the web browser to apply that style to all paragraph tags. In our example, we have used two different ways to tell it what to style. By doing so, you can scale the image upward or downward as desired. The style tag tells the web browser style information, but also what to style too. The background-size CSS property lets you resize the background image of an element, overriding the default behavior of tiling the image at its full size by specifying the width and/or height of the image. You will notice that we did have to change some things around. Our header is for information that we need to display the website correctly. We can move this information to our header. Our website looks better, but our HTML is starting to look messy with all of those descriptions in the paragraph tag. Let's increase the white-space, or padding, around our paragraph and center our text. If you want the entire image to show irrespective of the aspect ratio, then try this: background-image:url ('./images/bg.png') background-repeat:no-repeat background-size:100 100 background-position:center This will show the entire image no matter what the screen size. Adding a style description in CSS to our paragraph tag told the website how to style the paragraph. Now, our paragraph will be surrounded by a black border. Our page is pretty simple right now, and there is not much we can do, but let's begin by making our paragraph stand out so we can distinguish it from the background by adding a border. Now that we have a simple page, we can customize the style with CSS. It tells the web browser that the text is a paragraph. ![]() We only have one displayed element, the p tag. All of the displayed elements are between the body tags. The head tag contains the header information that is not displayed on the page but is needed to create the page. The html tag indicates which elements are part of the website. The text within a section is also intended to make this distinction easier to see. There are two types of tags, a tag that marks the beginning of a section using and one that marks the end of a section using. Whenever you see a word surrounded by it is a tag. As mentioned, HTML is a markup language, which means that it uses tags to mark what the text is. In case you are not familiar with HTML, let's quickly go over what all of the elements do. Our page will display "Hello World." Hello World A very basic website will be enough for us to begin playing with CSS. The transition property is a shorthand property used to represent up to four. Start with the free Agency Accelerator today. The shorthand background property will know what you mean if you declare one or the other.

This comes in useful in a few ways which we’ll get into later. ![]() Since CSS is just a style language, to use it, we first need something to style. While declaring the a solid color uses background-color property in CSS, gradients use background-image. ![]() Lazy Eights and Double Doodle teach children how to perform written tasks by training their bodies and eyes using large movements so that they will eventually be able to do the same using smaller movements on paper. Tracing and forming shapes in the vertical plane while standing at a board positions the hands right in front of the eyes with the head comfortably straight rather than bent over a piece of paper on a desk. In order to write children need to not only coordinate eyes and hands but coordinate using the eyes together as they move across the paper, fitting letters between lines. This activity promotes body awareness since if the child looks directly at one of her doodling hands, she will need to move the other hand without looking at it-by using her kinesthetic sense–that tells her how she is moving. This forces children to coordinate using both hands together and to pay attention to the direction of their movements. ![]() The teacher or occupational therapist might ask the child to form simple shapes, faces, letters or designs. ![]() Performing Double Doodleĭouble Doodle involves coloring or “doodling” with a piece of chalk or marker in each hand at the same time. ![]() The chalk offers more resistance requiring the child to use the small hand muscles in preparation for forming letters and numbers. Some children may find using a marker that glides on a white board easier at first and then after practice begin using chalk on a blackboard. However, tracing the large eight shape involves the whole body including the shoulder muscles-making it a multi-sensory experience. The up and down, left and right curvy movements teach children how to make the same movements needed to form letters. Students should perform the tracing activity three to five times with each hand and then several more times using both hands together on the marker. Lazy Eights develop visual tracking skills as the child watches his own hand movements. The large, exaggerated movements create rhythm and flow that promotes eye-hand coordination. The child traces repeatedly along the curves by either using a finger or drawing with a marker or chalk. Performing Lazy EightsĪ very large horizontal eight or infinity sign is drawn. These activities are beneficial to all students, even those with no disability. Brain gym Exercises for Autism Brain boosting Activities for Autism Autism. As these movements develop coordination between the right and left hemispheres-children develop bilateral integration. Printable Brain Gym Exercises is just what you are looking for.BRAIN GYM. Brain gym free exercises such as Lazy Eights and Double Doodle force children to use both hands together and cross midline as they make large movements at a blackboard. Children who have deficits in “bilateral integration” appear to be clumsy and struggle with fine-motor skills such as hand writing. Midline is an imaginary line that runs down the center of the body, dividing it into right and left sides. Symptoms include difficulties using both hands together to perform bilateral activities, lack of hand dominance in older children and avoidance of crossing the midline of the body. Their brains have difficulties processing what they see in order to read and write. Regardless of your treatment setting, we have what you need!
