Anatotitan Facts and Figures

Anatotitan Facts and Figures Name: Anatotitan (Greek for mammoth duck); articulated ah-NAH-toe-TIE-tan Living space: Forests of North America Recorded Period: Late Cretaceous (70-65 million years back) Size and Weight: Around 40 feet in length and 5 tons Diet: Plants Recognizing Characteristics: Huge size; wide, level bill About Anatotitan It required some investment to make sense of precisely what sort of dinosaur Anatotitan was. Since the revelation of its fossil stays in the late nineteenth century, this goliath plant-eater has been characterized in different manners, here and there passing by the now-unfashionable names Trachodon or Anatosaurus, or thought about a types of Edmontosaurus. Be that as it may, in 1990, a persuading case was introduced that Anatotitan merited its own sort in the group of huge, herbivorous dinosaurs known as hadrosaurs, a thought that has since been acknowledged by the greater part of the dinosaur network. (A more up to date study, in any case, demands that the sort example of Anatotitan was actually an obsolete example of Edmontosaurus, henceforth its incorporation in the as of now named species Edmontosaurus annectens.) As you would have speculated, Anatotitan (goliath duck) was named after its wide, level, duck-like bill. Notwithstanding, one shouldnt take this similarity excessively far: the snout of a duck is an extremely touchy organ (somewhat like human lips), yet Anatotitans bill was a hard, level mass utilized predominantly to uncover vegetation. Another odd element of Anatotitan (which it imparted to different hadrosaurs) is that this dinosaur was fit for running awkwardly on two legs when it was pursued by predators; else, it invested the vast majority of its energy in each of the four feet, chomping calmly on vegetation.

Ensure that you stress the significance to consistently locate a grown-up first before performing emergency treatment. Evaluation Ideas: Perform appraisal and assessment all through the whole exercise by having the understudies connect with attentive conversation based talk and apply what they have realized by putting the record cards into the right spots and noting why it’s critical to know medical aid security. Tuesday Name of Activity: Counting on Groceries | Reason for Activity: The motivation behind the movement is for the understudies to grasp ideas identified with wellbeing advancement by moving in the recreation center and finding out about sound food decisions just as doing a little essential math. Requirements: Counting to 6. Have some essential thoughts of what great nourishments resemble. Understudy will show solid practice and practices to keep up or improve individual wellbeing. Proposed Grade Level: 2 Materials Needed: Enough froth dice with the goal that every youngster has one Lots of plastic nourishments Two reusable shopping sacks 4 green containers (contingent upon how much â€Å"go food† you have) 2 red crates (contingent upon how much â€Å"whoa food† you have) Portrayal of Idea Spot on shopping sack with bunches of food decisions in it toward one finish of the play space. Spot the other shopping pack additionally with loads of food decisions in it toward the opposite finish of the play space. This takes into consideration greater development and less car influxes. Spot the shading bushels in the focal point of the play space. The green containers speak to the â€Å"Go Foods †sound food choices† and the red bins speak to â€Å"Whoa Foods †nourishments we can just eat each once in a while†. Every youngster will get 1 pass on. They will take the bite the dust to a self-space and roll the kick the bucket one time. In the wake of rolling the bite the dust they have to tally the spots. Each spot speaks to a bit of food they can get at the supermarket (shopping packs). When they gather the right measure of food from the sack to coordinate the move of the kick the bucket they take the food back to the crates. Once at the bushels they sort th e food into the green container for go nourishments and red bin for hold up nourishments. In the wake of arranging the nourishments they return to their kick the bucket and roll once more. They keep on doing this until the shopping sacks are vacant and the food is totally arranged. After all food is arranged take the youngsters back to the focal point of the play region. Have them sit around so they would all be able to see the crates. As the kids to distinguish the nourishments in the bushel and assess to check whether they put the nourishments in the right crates. Appraisal Ideas: I had the option to survey if the understudies could tally to six by watching their bite the dust roll and perceiving what number of bits of food they took when setting off to the shopping pack. I had the option to watch the youngsters sort the food and check whether they were arranging accurately for the food decisions they had. As a gathering I had the option to evaluate the general result by how effective they were in general with the arranging movement. Adjustments for Students with Disabilities: Children with portability issues could have a grown-up carry a container to them so they could sort simpler. Children with visual challenges could have the food distinguished for them and afterward have them mention to another youngster or grown-up what container to place to the food in. Children could work two by two if a kid experiences difficulty checking the spots on the bite the dust. Wednesday Name of Activity: Learning the food control pyramid | Motivation behind Activity: The student will apply information and conduct self-administration aptitudes to zones of sustenance and physical movement for solid development, improvement, and upkeep. Requirements: The understudy will pick propensities that forestall hearth sickness. : Students ought to know about the five nutritional categories, the amount of every nutrition class they ought to get each day, and what makes up a â€Å"serving† of food. 115.2 Health Edu. (b)(1) (A) Suggested Grade Level: 2 Materials required: - white board, - white board markers. - Class set of food schedule worksheets, - various arrangements of pyramid go fish game, - deck of cards Description of Idea Core interest: What is everyone’s most loved food? (Make a diagram on the white board, putting student’s most loved nourishments under the classification of the food pyramid in which it has a place) Explain which class the student’s most loved nourishments fall under, which classification we ought to have the a large portion of (grains) and which the least of (fats and oils)? Articulation of Objectives: To find out about the food direct pyramid and what nourishments are best for our bodies! Instructor Input: Can anybody name all the classes of the food manage pyramid? (Grains, vegetables, natural products, milk/dairy, meats and beans, and fats/sugars) Tell your neighbor what your preferred food is and which classification it fell under? Presently what amount of the various classifications, just as the one your preferred food falls under, do you figure you ought to eat every day? Grains-6 ounces Vegetables-2  ½ ounces Organic products 1â ½ cups Milk/dairy-3 cups Meats and beans-5 ounces Fats/sugars-know your cutoff points Oils (in spite of the fact that not a decent gathering, they are required in limited quantities for good wellbeing) We eat these nourishments since they furnish our bodies with the supplements we have to get things done.

Organizational Analysis Challenges Affecting the Firm - 1650 Words

Organizational Analysis and Management: Challenges Affecting the Firm, Declining Stock Prices, Employee Departures, Causes of the Problems (Research Paper Sample) Content: Organizational analysis and managementStudentà ¢Ã¢â€š ¬s nameCollege/University nameDateAbstractLeadership has been a defining factor of the state of affairs in the nation, business or family. Global perception has radically changed even though cultural dominance has been dominant. Cultural disintegration has been rapidly partially due to modernism and integration of different cultures worldwide. Therefore, sources of leadership, especially under political leadership, have partially propagated on the basis of culture.IntroductionApple is one of the most valuable firms in the market based on stock market valuation. The company has offered exemplary services and unique products led by the smartphone and tablet markets (Boker, 2000). However, the company has experienced a growth trajectory since 200, after the return of Steve Jobs, the visionary co-founder leader. However, Steve Jobs died, and the helm of the company was left to Tim Cook (Bur, 2000). The debate has been rife on the distinct differences between Cook and Jobs. Steve Jobs is considered a visionary, abrasive, unique and an intuitive decision maker while Cook is a mild-mannered, cordial and mostly finds consensus as a decision-making tool. Varied opinions on the situation of the firm have been advanced primarily on the basis of Jobs era and Post Jobs era (Cross, 2004). The former was witnessed with the rapid growth of the firm and innovative products unrivaled by none in the market. The latter, the Post Jobs era, now commonly referred as the Cookà ¢Ã¢â€š ¬s age, has witnessed a mixed bag of opportunities. The firmà ¢Ã¢â€š ¬s shares have nosed dived in the recent past, the smartphone and tablet market has been shrinking and employee departures of some of Steveà ¢Ã¢â€š ¬s Jobs main circle (Gladwell, 2000).The essays attempt to elaborate on the challenges facing the firm on the basis of the soft skills the current executives have unlike the previous management led by Jobs. The essay fu rther elevates the variables through the concepts of organizational behavior to explain on evident concepts and principles used. The essay further scrutinizes the causes of the challenges and offers solutions and recommendations that relate to the effective change in the firm. However, the company relies on the organization, the management, the culture adopted and ways of effecting changes in the business.Challenges affecting the firmEvery firm faces internal and external challenges relating to the business. There has been a bubble in technology company in recent years especially in the United States (Grant, 2014). The nation hosts many technology companies such as Google, arguably emerging competitors to Apple. The sector has witnessed rapid innovation of products with the culmination of smartphones and tablets (Grant, 2013). Apple has recently undergone succession after legendary co-founder and chief executive demise. The essay highlights some of the challenges faced by the firm o n the basis of soft differential skills between the two leaders.Declining stock pricesThe stock market is arguably the most fluctuating investment asset. The securities market is believed to fluctuate according to cycles faced by the firm (Kilworth, 1990). Apple stock has been recently trading below the high of US$ 700; last reached in 2012. During the period, Cook was in charge though analysts presume the short time after taking over should not over varied optimism rather than a long-term look at Cookà ¢Ã¢â€š ¬s Performance. Contrastingly, revenues for the firm have been on an upward trajectory since the death of Steve Jobs. However, critics are against Cookà ¢Ã¢â€š ¬s performance citing Jobs would have done more. During Cookà ¢Ã¢â€š ¬s tenure investors have earned healthy dividends, unlike Jobà ¢Ã¢â€š ¬s era where the firm retained earnings. The stark contrast between the two elaborates on the different thoughts for the future of the company. Cook focuses on all the facets of the business. During the uproar for the Map app disaster, Cook flew to China to offer the firmà ¢Ã¢â€š ¬s utmost regret, that was a stark contrast of the abrasive Jobs, whom analysts believed would not have travelled to China. Furthermore, the bruising battle with Samsung supported by Jobs would be different under Cook, especially since settling a feud with Google.Employee departuresPower is derived from the relationships with the employees. Steve Jobs highly considered the best performing workers and disliked the average performers. During Jobs reign, frequent delays in launching of new products were related to the reliance of the best performing workers too few to meet deadlines. However, Jobs was surrounded by gurus in various departments of the business (Pfeffer, 2010). Scott Forstall was an ally of Steve Jobs and headed the IOS division. Forstall was regarded more similar to Steve Jobs. Forestall was regarded creative, egocentric, energetic and a legitimate successor to Steve Jobs. Furthermore, both were fans of skeuomorphism in software engineering. After Scottà ¢Ã¢â€š ¬s departure Cook elevated John Ive to the head of all design and new head of software engineering, Craig Federighi. Since Cook took over, the chief executive has been pursuing to increase the number of directors on the board as most are considered Jobs loyalists. The stark contrast explains the distinct characteristics of the two leaders. While Steve Jobs excelled with his abrasive, dictatorial and intuitive abilities to enhance creativity, though haphazardly in nature. Cook has chosen a clearer path creating structures through the new positions and delegated decision making amongst employees. Consequently, the incumbent chief executive officer is different from Steve Jobs. Steve Jobs was visionary, but Cooks attempts to focus on consistency. Both leaders have used the power of differently articulate policies or changes in the firm. Furthermore, changes were more accepted across the fir m.Causes of the problemsThe challenges facing Apple relate to the evident woes facing the market. Market perceptions elaborate on the firmà ¢Ã¢â€š ¬s performance. Apple has been consistent on returns for investors but still performs poorly in the stock exchange. The essay elaborates on the actual problems belittling the firm.CompetitionCompetition in the devices market has heated up as more device makers use Googleà ¢Ã¢â€š ¬s Android platform. Recently, Nokia announced plans to utilize the Android platform on the basis of popularity in the devices market. Some of the firms that use the Android platform include Samsung. Motorola, Wiko, Huawei, and LG. However, Apple increased market share from 37% to 39% of the devices market in the USA. Therefore, the debate has been rife on IOS unfriendliness to the end user through apps for the end user. Moreover, the software exclusivity has been a subject of concern especially as more phone devices use the Android platform. Increased competiti on has been expressed as one of the factors of the poor showing in the stock market. Furthermore, the perception of seamless succession has not fully convinced the investors. Jurists are yet to rate Cookà ¢Ã¢â€š ¬s performance especially regarding the rather shorter period in the firm, unlike Steve Jobs. Furthermore, launching of new products has been slower under Cook, leading to queries on the ramifications of innovation Jobs may have left. Jobs led the firm to increased growth and dominance in the devices market where the market was logically new and growing. However, differing soft skills between Cook and Jobs, elaborate on differing market tactics employed during both reigns. Jobs was more abrasive and foresighted and focused on the core business of the firm. Moreover, Jobs presided over the acquisition of related firms and low valued companies, unlike Cook, who has overseen the acquisition of Beats Music and Electronics. The deal was the priciest acquisition by Apple. The exa mple explains that Cook considers himself a manager and allows for diversity while Jobs was an innovator that led from the front. Furthermore, Cook delegated a launch of the firmà ¢Ã¢â€š ¬s products to Craig, a widely publicity event, unlike Jobs, who presided all devices launch.Management differencesManagement styles elaborate on the relationships between employees. The models explain the culture of the firm and performance of the firm. Recently, governance mechanisms have been forwarded to explain the importance of the management structures. Corporate governance has been used to operate businesses more transparently, produce environmental friendly products and serve soc...

Investment And The Factors To Consider Before Investing - 275 Words

Investment And The Factors To Consider Before Investing (Essay Sample) Content: RENSON OMUMUFACTORS THAT DETERMINE INVESTMENTIntroductionInvestment is very essential to any country as it helps the society grow thus improving the standards of living. This paper will primarily focus on the key factors that determine the level of investment in a modern society.Government policies and regulation is very important in determining the level of investment. This is so because if the regulation put down by a government is considered too exorbitant by investors, then it will be very difficult for any investment to take place. This means that government ought to figure out and implement regulations that are fair to both parties.Another important factor is the overall economic condition. A society having an increase in its economic growth will definitely have more investors. Economic growth will mean more and better opportunities and this will definitely increase investment (Mukherjee 2012).Consumer demand is another vital aspect as it greatly induces the lev el of investment in the economy. This means that if the current demand for consumer goods increases, then it means that more investments will be made. In short if consumer demand is low then investments opportunities will also be low.Inventions and innovations are very important to any economy. This is so because they tend to raise the inducement to invest. If for example, a certain invention and technological improvements lead to competent methods of production that reduce cost, the MEC of new capital assets will rise, which in turn will encourage firms to make larger investments (Mukherjee 2012).Last but not least is the growth of the population. A grow...

De Broglie Wavelength Hypothesis Overview

The De Broglie hypothesis proposes that all matter exhibits wave-like properties and relates the observed wavelength of matter to its momentum. After Albert Einsteins photon theory became accepted, the question became whether this was true only for light or whether material objects also exhibited wave-like behavior. Here is how the De Broglie hypothesis was developed. De Broglies Thesis In his 1923 (or 1924, depending on the source) doctoral dissertation, the French physicist Louis de Broglie made a bold assertion. Considering Einsteins relationship of wavelength lambda to momentum p, de Broglie proposed that this relationship would determine the wavelength of any matter, in the relationship: lambda h / p recall that h is Plancks constant This wavelength is called the de Broglie wavelength. The reason he chose the momentum equation over the energy equation is that it was unclear, with matter, whether E should be total energy, kinetic energy, or total relativistic energy. For photons, they are all the same, but not so for matter. Assuming the momentum relationship, however, allowed the derivation of a similar de Broglie relationship for frequency f using the kinetic energy Ek: f Ek / h Alternate Formulations De Broglies relationships are sometimes expressed in terms of Diracs constant, h-bar h / (2pi), and the angular frequency w and wavenumber k: p h-bar * kEk h-bar * w Experimental Confirmation In 1927, physicists Clinton Davisson and Lester Germer, of Bell Labs, performed an experiment where they fired electrons at a crystalline nickel target. The resulting diffraction pattern matched the predictions of the de Broglie wavelength. De Broglie received the 1929 Nobel Prize for his theory (the first time it was ever awarded for a Ph.D. thesis) and Davisson/Germer jointly won it in 1937 for the experimental discovery of electron diffraction (and thus the proving of de Broglies hypothesis). Further experiments have held de Broglies hypothesis to be true, including the quantum variants of the double slit experiment. Diffraction experiments in 1999 confirmed the de Broglie wavelength for the behavior of molecules as large as buckyballs, which are complex molecules made up of 60 or more carbon atoms. Significance of the de Broglie Hypothesis The de Broglie hypothesis showed that wave-particle duality was not merely an aberrant behavior of light, but rather was a fundamental principle exhibited by both radiation and matter. As such, it becomes possible to use wave equations to describe material behavior, so long as one properly applies the de Broglie wavelength. This would prove crucial to the development of quantum mechanics. It is now an integral part of the theory of atomic structure and particle physics. Macroscopic Objects and Wavelength Though de Broglies hypothesis predicts wavelengths for ​matter of any size, there are realistic limits on when its useful. A baseball thrown at a pitcher has a de Broglie wavelength that is smaller than the diameter of a proton by about 20 orders of magnitude. The wave aspects of a macroscopic object are so tiny as to be unobservable in any useful sense, although interesting to muse about.
