Cobweb Spiders of the Family Theridiidae

From the harmless house spiders to the venomous widows, the family Theridiidae includes a large and diverse group of arachnids. Chances are theres a cobweb spider somewhere in your house right now. Description Spiders of the family Theridiidae are also called comb-foot spiders. Theridiids have a row of setae, or bristles, on their fourth pair of legs. The setae help the spider wrap its silk around captured prey. Cobweb spiders are sexually dimorphic in size; females are larger than males. Female cobweb spiders have spherical abdomens and long, slender legs. Some species practice sexual cannibalism, with the female eating the male after mating. The black widow gets its name from this practice. Cobweb spiders build irregular, 3-dimensional webs of sticky silk. Not all spiders within this group build webs, however. Some cobweb spiders live in social communities, with spiderlings and adult females sharing the web. Others practice kleptoparasitism, stealing prey from other spiders webs. Classification Kingdom – AnimaliaPhylum – ArthropodaClass – ArachnidaOrder – AraneaeFamily – Theridiidae Diet Cobweb spiders feed on insects, and occasionally other spiders. When an insect becomes ensnared in the sticky strands of the web, the spider quickly injects it with venom and wraps it tightly in silk. The meal can then be consumed at the spiders leisure. Life Cycle Male cobweb spiders roam in search of mates. In many species, the male uses a stridulatory organ to signal his interest in females. Though some Theridiid males do get eaten after mating, most survive to find another mate. The female cobweb spider wraps her eggs in a silk case and attaches it to a point near her web. She guards the egg sac until the spiderlings hatch. Special Adaptations and Defenses With dozens of genera in the Theridiidae family, adaptations and defenses are as diverse as the cobweb spiders. Argyrodes spiders, for example, live along the edges of other spiders webs, dashing in to grab a meal when the resident spider isnt around. Some Theridiids mimic ants, either to trick potential ant prey or to fool possible predators. Range and Distribution Cobweb spiders live throughout the world, with more than 2200 species described to date. Well over 200 Theridiid species live in North America.

The Islamic Revolution and its Impac on Marji’s Family Essay

The Pahlavi dynasty caused Marji’s family and other Iranian citizens to become dysphonic. The dynasty mismanaged Iranian money and was manipulated by Western nations. Enmity grew towards the monarchy and ultimately the Iranian people wanted a revolution. Marji’s family had strong animosity toward the Shah. Many of Marji’s family members as well as others fought against the Shah. But the Islamic Revolution took a turn that many were not prepared for. Mohammad Reza Pahlavi (The Shah), the son of Reza Shah took the throne after his father on September 16, 1941. The Shah continued his father’s politics and modernization of Iran. He proceeded to Westernize Iran by having the education structure â€Å"(primary, secondary, higher†¦show more content†¦Citizens of Iran were infuriated by the calamitous coup d’à ©tat and overthrowing of Mossadeq. Dr. Mohammed Mossadeq was deemed by Iranian people as a hero. In addition to the complication s with the oil, The Shah’s reputation began to deteriorate. The Shah was scrutinized as a puppet of the Western nations, particularly the United States. Citizens of Iran began to have aversion towards the actions of the monarchy. The Shah altered the Iranian solar calendar inducing outrage amongst many Iranian Muslims. Another issue was the Shah’s distribution of money. The Shah spent over 300 million dollars in extravagant luxuries during a three-day celebration; rather than using the money for the needs of Iran. Citizens of Iran suffered greatly from The Shah’s regime. He was considered a dictator and used harsh punishments for rebellions. The Shah was a corrupt leader who oppressed the Iranian people. Citizens of Iran finally had enough with the Shah and decided to overthrow him. The Islamic Revolution (Iranian Revolution) lead by Ayatollah Kjomeini began in 1977. Interminable protests against the Shah’s dynasty commenced, and by January 19 78, the protests became deadly. â€Å"Hundreds of Islamist students and religious leaders in the city of Qom were furious over a story in the government-controlled press they felt was libelous.† (Wikipedia) It was estimated that over seventy

Shakespeare Sonnet 18 This Sonnet Is By Far One Of The Most Interest Essay Example For Students

Shakespeare Sonnet 18 This Sonnet Is By Far One Of The Most Interest Essay ing poems in the book. OfShakespeares sonnets in the text, this is one of the most moving lyric poems that I have ever read. Thereis great use of imagery within the sonnet. This is not to say that the rest of the poems in the book were notgood, but this to me was the best, most interesting, and most beautiful of them. It is mainly due to thesimplicity and loveliness of the poems praise of the beloved woman that it has guaranteed its place in mymind, and heart.The speaker of the poem opens with a question that is addressed to the beloved, Shall Icompare thee to a summers day? This question is comparing her to the summer time of the year. It isduring this time when the flowers are blooming, trees are full of leaves, the weather is warm, and it isgenerally thought of as an enjoyable time during the year. The following eleven lines in the poem are alsodedicated to similar comparisons between the beloved and summer days. In lines 2 and 3, the speakerexplains what mainly separates the youn g woman from the summers day: she is more lovely and moretemperate. (Line 2) Summers days tend toward extremes: they are sometimes shaken by rough winds(line3) which happens and is not always as welcoming as the woman. However in line 4, the speakergives the feeling again that the summer months are often to short by saying, And summers lease hathtoo short a date. In the summer days, the sun, the eye of heaven (line 5), often shines too hot, or toodim, his gold complexion dimmed (line 6), that is there are many hot days during the summer but soonthe sun begins to set earlier at night because autumn is approaching. Summer is moving along tooquickly for the speaker, its time here needs to be longer, and it also means that the chilling of autumn iscoming upon us because the flowers will soon be withering, as every fair from fair sometime declines. (Line 7) The final portion of the sonnet tells how the beloved differs from the summer in various respects. Her beauty will be one that lasts forever, Thy eternal summer shall not fade. (Line 9), and never end ordie. In the couplet at the bottom, the speaker explains how that the beloveds beauty will accomplish thiseverlasting life unlike a summer. And it is because her beauty is kept alive in this poem, which will lastforever. It will live as long as men can breathe or eyes can see. (Line 13)On the surface, the poem is onthe surface simply a statement of praise about the beauty of the beloved woman and perhaps summer tothe speaker is sometimes too unpleasant with the extremes of windiness and heat that go along with it. However, the beloved in the poem is always mild and temperate by her nature and nothing at all like thesummer. It is incidentally brought to life as being described as the eye of heaven with its goldcomplexion. The imagery throughout the sonnet is simple and attainable to the reader, which is a keyfactor in understanding the poem. Then the speaker begins to describe the summer again with the darlingbuds of May giving way to the summers lease, springtime moving into the warmth of the summer. The speaker then starts to promise to talk about this beloved, that is so great and awing that she is to liveforever in this sonnet. The beloved is so great that the speaker will even go as far as to say that, So longas men breathe, or eyes can see, the woman will live. The language is almost too simple when comparingit to the rest of Shakespeares sonnets; it is not heavy with alliteration or verse, and nearly every line is itsown self-contained clause, almost every line ends with some punctuation that effects a pause. But it is thisthat makes Sonnet18 stand out for the rest in the book. It is much more attainable to understand and itallows for the reader to fully understand how great this beloved truly is because she may live forever in it. .u8f33021cb66b712134e339502c044db4 , .u8f33021cb66b712134e339502c044db4 .postImageUrl , .u8f33021cb66b712134e339502c044db4 .centered-text-area { min-height: 80px; position: relative; } .u8f33021cb66b712134e339502c044db4 , .u8f33021cb66b712134e339502c044db4:hover , .u8f33021cb66b712134e339502c044db4:visited , .u8f33021cb66b712134e339502c044db4:active { border:0!important; } .u8f33021cb66b712134e339502c044db4 .clearfix:after { content: ""; display: table; clear: both; } .u8f33021cb66b712134e339502c044db4 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u8f33021cb66b712134e339502c044db4:active , .u8f33021cb66b712134e339502c044db4:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u8f33021cb66b712134e339502c044db4 .centered-text-area { width: 100%; position: relative ; } .u8f33021cb66b712134e339502c044db4 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u8f33021cb66b712134e339502c044db4 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u8f33021cb66b712134e339502c044db4 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u8f33021cb66b712134e339502c044db4:hover .ctaButton { background-color: #34495E!important; } .u8f33021cb66b712134e339502c044db4 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u8f33021cb66b712134e339502c044db4 .u8f33021cb66b712134e339502c044db4-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u8f33021cb66b712134e339502c044db4:after { content: ""; display: block; clear: both; } READ: Discrimination Against The Elderly EssayAn important theme of the sonnet, as it is an important theme throughout much of the poetry in general,is the power of the speakers poem to defy time and last forever. And so by doing this it is then carryingthe beauty of the beloved down to future generations and eventually for al of eternity. The belovedseternal summer shall not fade precisely because it is embodied in the sonnet: So long as men canbreathe or eyes can see, (line 13) the speaker writes in the couplet, So long lives this, and this gives lifeto thee.(Line 14) With this the speaker is able to accomplish what many have done in poetry and that isto give the gift of an et ernal life to someone that they believe is special and outshines everyone else aroundthem. Perhaps it is because of a physical beauty that the speaker see, but I believe that it is more becauseof the internal beauty as seen in line 2, Thou art more lovely and more temperate, that the beloved isdeserving to live on forever.

Tesla Motors free essay sample

The Global Business Community The first macroenvironmental factor that Tesla Motors faces is the society and subcultures. In this day in age consumers worldwide have increased their knowledge and sensitivity about its environment. Numerous companies have catered to this need of becoming more environmentally responsible by offering products that are â€Å"green† or environmentally friendly. This new growth amongst people and organizations alike of becoming more environmentally conscious has created an opportunity for Tesla Motors with its brand of product.Tesla Motors produces and sells fully electric cars as well as electric vehicle powertrain components that give off no tailpipe emissions. Also Tesla motor vehicles cut CO2 emissions in half compared to gas burning automobiles that currently dominates the roads today. Environmental consciousness is what Tesla Motors is built on and its pursuit of diminishing dependence upon a diminishing resource for their consumers is what the company values most and depends on most for increasing revenue. We will write a custom essay sample on Tesla Motors or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The second macroenvironmetal factor that Tesla Motors runs into is the demographics.The demographics factor may pose as a major problem for Tesla’s success in the future as its product only appeals to those that are able to afford their vehicles. Although Tesla Motors offers a first-rate vehicle when it comes to performance, efficiency, and class the price for the fairly new automobile company is not economically friendly. Currently Tesla’s prices can range from the base vehicle Model S which currently costs roughly $58,000 up to its â€Å"signature edition† which is estimated at $105,000.With its above average cost of the high end fully electrical cars Tesla must integrate a more concentrated segmentation strategy in targeting the correct demographics to foster the company’s success. Tesla Motors should also take into consideration of tackling demographics in regions with higher gas prices compared to others. According to the American Automotive Association California, Hawaii, Alaska, Connecticut, and New York are among the states with the highest gas prices (Kurtzleben, 2011). In accomplishing this Tesla will be able to market to demographics that can offer a higher incentive in purchasing their fully electric vehicles.The third macroenvironmental factor Tesla faces is in regards to the economic factors. One economic factor that can possibly affect the Tesla would be the prices of petroleum dropping to a low cost for consumers and possibly staying at an affordable price. With an affordable price on gasoline, consumers would be less likely to look for alternatives to combat rising gas and oil prices that we see today, making the high-priced fully electric Tesla vehicle even more unattractive. The economic downturn can also be an ailing factor for Tesla Motors as well. The economic collapse has caused the buying capacity of consumers to dramatically decrease making individuals across the country a lot more conscious about the spending their hard earned dollar. The automobile industry as a whole has struggled overall with battling record losses in revenue and waiving workers. Being that it is a fairly new competitor within the industry Tesla will find it very difficult for selling and staying above its break-even point with its high-end luxury fully electric vehicle. The forth macroenvironmental factor Tesla faces is the natural and physical factors.The increased usage of oil and fossil fuel which is mainly being used for transportation and the decreasing of the resource globally play as an opportunity and advantage for Tesla Motors. â€Å"Petroleum currently fuels 95% of the United States transportation sector, a sector that demands nearly 28% of total usage† (Musk, 2012). With Tesla Motors’ fully electric vehicles offer consumers a s ubstantially alternative towards saving money from not ever relying on purchasing gas at an ever increasing price due to its low supply and high demand of petroleum. Minimizing the dependence on petroleum not only reduces emissions, but also will help build a stronger energy economy (Musk, 2012). The fifth macroenvironmetal factor Tesla faces is in consideration of political and legal issues. Tesla has already been involved in several lawsuits. One that has been most notarized is the lawsuit filed against its competitor Fisker Automotive in early 2008 for stealing design ideas and confidential information such as business plans, technology, and trade secrets. Henrik Fisker was hired by Tesla to design its WhiteStar model vehicle in 2007.After gaining access to designs and confidential information which is Tesla’s competitive advantage he then used the information which enabled Fisker to develop his own high-end electric car which was called Karma. After consulting with an arbitrator Tesla lost its case 7 months after filing the suit due to the finding an interim award in Fisker Automotives favor. The sixth and final macroenvironmetal factor Tesla Motors faces is technology. Tesla holds a technological advantage over all of its competitors in comparison with to the overall performance of the vehicle.Tesla’s electric powertrain found in each vehicle allows higher driving efficiencies. With Tesla’s understanding of using energy efficiently the company has created vehicles with superior design by improving technologies of vehicle road-load which encompasses wind resistance, mechanical friction, and tire rolling resistance; energy conversion losses, as well as electric vehicle efficiency. Overall the driving efficiency is 88% compared to 20-25% for traditional gas-powered cars (Musk, 2012). Although hybrids also increase the total efficiency of internal combustion they are still less efficient than Tesla vehicles (Musk, 2012).Another technological advantage Tesla’s has is its affordability in fueling the vehicle with electricity rather than gas, making it a s ound financial decision for consumers. â€Å"Tesla vehicles cost as little as $5 to charge; equivalent to $0. 02 per mile. Alternatively, a gasoline-powered car that is rated at 20 mpg cost $0. 15 per mile† (Musk, 2012). Tesla’s has a competitive advantage in regards toward its technology used within its product. However, the main concern is how long Tesla Motors will be able to hold its competitive advantage in regards toward its technology over time. The MarketHeading into the microenvronmental analysis of the paper the first factor that Tesla Motor’s faces is the collaboration. Collaboration with other companies can be beneficial and viewed as a positive for both parties if performed properly. With Tesla Motors’ technological advancements for its electric cars the company has teamed up with major automobile company Toyota towards supplying the company with control systems, batteries, and motors Toyota’s new electric vehicle the RAV4 SUV (Bullis, 2012). Tesla has also recently agreed to provide similar electric car supplies for Mercedes-Benz in a similar deal (Bullis, 2012).The collaboration microenvironmental factor can be turned into an opportunity for Tesla Motors as leverage. If the company manages to not succeed as an independent automobile manufacturer, Tesla still can have the ability to produce the proper technologies needed in developing an electric car for larger manufacturers. Through collaboration Tesla can also develop itself in become an attractive company to be acquired by larger automobile companies such as Toyota and Mercedes- Benz respectfully. The second microenvironmental factor Tesla Motors faces is in regards to competition. With nearly every major automobile manufacturer gearing up plans to roll out with their very own electric car Tesla now has to compete with the likes of General Motors, Ford, and Nissan. However these companies will be indirectly competing with Tesla for market share within the niche. Companies that will be directly competing with Tesla are Mercedes and BMW in the market for high-performance luxury electric vehicles (Bullis, 2012). Competition has been expanded into a much broader scope for Tesla Motors since the company was founded back in 2003.Along with other smaller automobile manufacturers that Tesla must compete with, Tesla has to also compete with companies that provide other energy efficient alternatives such as hybrids, hydrogen powered, flex fuels, and compressed natural gas. The third microenvironmental factor Tesla Motor must account for is its suppliers. It is imperative for companies to have a positive relationship with suppliers in order for the procurement process to be run efficiently and effectively especially when there is more than one supplier needed to fulfill the completion of the overall product. Procurement is a series of steps that a company takes to obtain or acquire necessary materials (Magal Word, 2009). It is vital that Tesla stays in complete control of its product lifecycle process as the company deals with many suppliers from different countries all over the world. Besides the company’s powertrain which is built at Tesla’s at headquarters in California, car parts for design such as body panels are produced in France, as well as battery cells shipped from Japan (Musk, 2012).Tesla can use strategies such as locking in lower prices for different supplies to ensure savings overtime if prices were to be raised. The fourth and final microenvironmental factor that must be taken into consideration on behalf of Tesla Motors are the regulators. Tesla has to be aware and make proper adjustments to its business plans once government regulation occurs. In January of 2012, California, adopted the strongest new clean-air regulation in the United States. California will mandate that one out of seven cars sold in 2025 are plug-ins or full electrics (Woodyard, 2012).
