Praying Mantiss Essays - Fauna Of California, Mantis, Mantidae

Praying Mantis's MANTODEA Most commonly known as the Praying Mantis, order mantodea is a group of about 1800 carnivorous insects which prodominatley live in tropical regions of the earth. Though certain species can be found in locations with moderate climate. With an extremely striking appearence, mantids almost have human like qualities with the ability to hold an erect stance, and arms that face forward. A very efficient killer, mantids were created for hunting and killing prey. Order Mantodea is in the subclass Pterygota. As with all classifications there can be debates on where certain orders or species belong. Historically there has been some confusion on whether Mantodea deserves there own order. Some experts have placed Mantodea in the dictyoptera order along with cock roaches (Ramel 1996, Jaques 1981, Phoenix Zoo). Others say mantids belong in Orthoptera, which consists of grasshoppers. Experts say this is due to their large pro notum (Stokes 1983, Borror and White 1970). The emerging consensus around the position of Mantodea believes Mantodea constitute their own independent order of insects. Mantids can be characterized by their triangular head, and filiform antennae. This head has the ability to turn 180 degrees. With their prominate pair of compound eyes located on Peters 2 the sides of the head, the mantis can almost see 360 degree's around. However the sharpest vision is located in the compound eye's center, for the mantis to optimaly see objects it must turn its head so that the eye is facing the object. These eyes are extremely sensitive to light, changing from light green or tan in bright light, to dark brown in the dark. The prothorax of the mantis is another aid in giving them their distintive appearence. This prothorax has the ability to bend and twist which aids in the mantids ability to see close to 360 degrees around. The two long ?raptorial? front legs are adapted to seize and hold prey. The coxa connects the tibia which has sharp spines to firmly hold prey. The femur has matching groves where the spine on the tibia fold into. This creates a ?jack knife? effect that allows the insect to assume it's distinctive praying position. The other four legs of the mantis are designed for locomotion. These legs can regenerate if broken, but only in the molting process. These limbs that regenerate are always smaller than they were originally. A full grown adult that no longer molts no longer possess the ability to regenerate limbs. The front ?raptorial? limbs do not regenerate if broken. Because of their large bulky bodies mantids are fairly weak flyers. They have four pairs of wings. The first pair are leathery tegmina wings that lay over the inner pair. The Peters 3 mambrenous inner pair are folded under the first pair and are used for flight and to startle enemies. The large segmented abdomen houses the digestive system and reproductive organs. The male mantis has 8 segments, and the females are born with 8 segments as well. But with each succesive molt in the female the last two segments begin to overlap resulting with 6 segments left. Sixty percent of mantid species possess an ultrasonic ear on the under side of the metathorax, especially those that have wings. The mantid is an ?auditory cyclops?, which means it only has one ear. The ear is 1mm long with cuticle like knobs at either end and two ear drums buried inside. The ear is specially tuned to very high ultrasonic freqeuncies of sound waves from 25 to 65 kilohertz. Apparently, the ears primary purpose is designed to respond to the ultrasonic echo-location signal used by hunting bats. The mantis primarily uses its ultrasonic ears while in flight. When a mantis senses a bat's ultrasonic echo at close range, it curls it's abdomen upwards and thrusts its legs outward creating a drag and resulting in a sudden aerial stall. This flight manuever of the mantis creates an unpredictable flight pattern for the bat, and is very effective at avoiding hungry bats. There are three ways to distinguish between female and male mantodea. The male has 8 segments, while the female has Peters 4 The second is size, the female is always bigger than the male. The third is behavior, the male mantis is more prone to take flight in search of a mate, while the female often remains stationary. Mantids are extremely predacious feeders, only eating live prey, or prey that is moving, and hence appears alive. Varying on the species, you can see what diet preferences are. Some species only eat ?soft bodied bugs?, insects that can be easily devoured. While some species will eat anything from small birds to

There are several aspects of these photographs that I would like to discuss, namely the interplay of light and shadow and structured space. These are the issues should be examined. There are several qualities of these p hotographs that make them almost unforgettable. One of them is structured space. For instance, one can look at his picture of Petrified Forest National Park1. There is horizontal divide that separates shaded and illuminated parts of the mountain. Overall, I say that such a moment is very difficult to capture and it is a skill of a great photographer. It is worth noting that this picture was taken at sunset and but the Moon is still visible. Moreover, this picture has a very rich palette. The viewer can see how grey color of the mountain is transformed into fiery orange and this image is unforgettable. In my opinion, this effect is difficult to produce because one has to occupy a certain position and use a certain type of camera. Overall, these qualities distinguish Jack Dykinga among others.

While working on this project, I attempted to recreate some of the techniques used by Jack Dykinga. For example, I attempted to emulate his palette in which there is a divide between dark and bright colors. In my opinion, this effect is very difficult to achieve because a photographer should choose a certain angle and moment when one can see an interplay of light and shadow. This task is quite challenging. Furthermore, one has to choose the best moment at which one can capture the game of light and shadow. Certainly, I will try to develop my own style of photography. However, I do like Dykinga’s perception of nature and his ability to highlight the beauty of landscape. The pictures discussed in the paper show that that a photographer is not a mere observer of people or physical environment. This individual should be able to see how colors, shapes, and space can interact. Only in this way, one can create unique and unforgettable images.

Patents Act Essay Example | Topics and Well Written Essays - 2250 words

Patents Act - Essay Example Any questionable aspects to MCJ’s patent could be used by DD to approach the Comptroller to ascertain whether DD is entitled to the patent in view of the fact that it had applied as early as July 2002 and the questionable nature of MCJ’s purported earlier application. If the Comptroller determines that MCJ is not entitled to ownership of the patent, then he will â€Å"reach a solution which will provide a reasonable opportunity for the patent to be exploited should there be a demand for it.†The Comptroller can also amend the application and also has the power to license DD’s A-UK patent. However, since MCJ’s license has already been published, remedies in this area appear limited. Since MCJ’s is the earlier patent based on priority date, this means that DD may be liable for infringing the patent of MCJ. However, since DD was not aware of the development of a similar product but developed its cylinder coating product independently, and is also trying to acquire a license from MCJ to use the product, it is possible that no charges may be brought by MCJ. In respect to the rights in patents, it may be noted that the cylinder coating process may still be protected since DD â€Å"did not know of the earlier transaction, instrument or event† and was unaware of the published application of MJC Ltd. An â€Å"innocent infringer† will be exempt from any liability for damages.

LION KING film analysis of the leadership issues in the film Essay

LION KING film analysis of the leadership issues in the film - Essay Example The question is, what are those qualities that make a strong leader? Why is it that some leaders are loved and respected by their followers forever while others fail to maintain the faith from their followers? The answer lies in their leadership styles. The movie â€Å"The Lion King†, is an excellent example of different leadership styles (1994). Through the characters of Mufasa, Scar and Simba, the movie has clearly and distinctly described the qualities that make a strong and a weak leader. Leadership can be defined as â€Å"an influence relationship among leaders and followers who intend real changes that reflect their mutual purpose.† (Rost 1991). This definition shows that a relationship is developed between a leader and the followers only when they have a common goal to achieve (Rost 104). A relationship cannot be developed if the goals of the leader and the followers differ. In the movie ‘The lion king’, Mufasa is able to gain respect and love from his followers because he is able to understand their needs and works towards the fulfillment of those needs harmoniously. Mufasa displays a transformational leadership style through the quality of the relationship that he develops with his followers. A strong leader is the one who is able to form a relationship with his followers not on the basis of expectations but on the basis of trust and understanding. Transformational leaders take effort in nurturing the sense of self worth in the followers and boosting their self-esteem (Bass 1998). When the followers realise that their individual qualities are being recognised and nurtured by their leader, they feel that their individual needs are being taken care of. They feel enthusiastic and energetic under the guidance of such leader and hence, commit themselves to the achievement of goal in a genuine way. They are willing to give their best in an effort to reach their purpose (Bass 1998). In the movie ‘The lion king’, Mufasa

Three Men in a Boat Essay Example for Free

Three Men in a Boat Essay British humor is often hard to grasp for Indians, with their references and rambling. But Jerome K. Jeromehits the nail on the head with ‘Three Men In A Boat‘ and brings out British absurdities and traditions in a comic way. This book though meant to be a travelogue of sorts ended up, inexplicable as one of the most loved funny stories of all time. And even after 100+ years since publishing, the jokes remain fresh and witty! It outlines the story of three men – Jerome and his two friends, Harris and George and their dog, a fox terrier called Montmorency on their holiday on the River Thames in Oxford, England as the three men suffer from some weird ailment. So they set themselves off on a trip to cure themselves – a boating trip. Apparently, that was quite common in those times, which is around 1889 when the book was published. The travelogue portion is quite apparent as along the trip, Jerome mentions all the villages and landmarks they pass, such as Hampton Court Palace, Hampton Church, Monkey Island, Magna Carta Island, Marlow etc and the few titbits about the culture in those places. But this, though intended to be the main part of the book was overshadowed by the comic instances that cropped up and the book gave up and now is just a humorous tale. Jerome often digresses and starts off random anecdotes and ponders upon life. From friends to friends-of-friends to historic characters, Jerome’s detours truly know no bounds. He gives up brilliant character sketches of not only Harris and George, but of Montmorency also. From how his Aunt Podger used to take a week long refuge at her mother’s place when Uncle Podger donned the role of a handyman trying to fix â€Å"little† things in the house to how the making of Irish Stew from all the leftovers compelled Montmorency to add his bit by bringing a dead-water rat, each episode will leave you giggling in delight. And the best is that it describes the common frustrations of life that you and I go through. The downside of the book is that the return journey back up the Thames is wrapped up in just one chapter which leaves you slightly hurt and bewildered at the sudden ending. But the wry and sarcastic humour and wit with the misadventures, exaggerations, mad caps, twists and sheer silliness in this P. G Wodehouse-y book leaves you pleasantly happy at the end. Of course, one can’t help but read this book in a proper British accent. Be it in their heads, or out loud. And that would be perfectly fine.

Important Formative Experience That Made Me The Adult I Am Today :: essays research papers

Important Formative Experience I have had many theater-related experiences. Every chapter that I have read in my theater book has allowed me to make a connection to my past experiences with theater performances. I have also seen many plays and could relate to things an audience sees by reading the book. My first theater experience ever is when I was in the Nutcracker. We did a ballet performance for this play. I was very young when I did this, but I remember my instructor always saying that we must make contact with our audience through movements. Since in ballet you can not talk, you have to express the emotions that you are feeling to the audience through movement. This was very difficult. I must say that acting with words is a lot easier than acting through dance. In chapter one of my theater book, I was able to make the connection of "theater" is "work" to my experience of work in a theater with school plays. I know that I did not work as hard as professionals do, but I did work hard. For three months, we practiced everyday except for Saturday and Sunday, from 3:30 to 6:30. I helped with a lot of the choreography, so that made my days even longer and harder. However, this was also an enjoyable work experience for me. While reading the passage, I was able to relate with some of the "theater times" because of my play director. My high school director was very talented in directing plays. He would talk to us as if we were professionals and made us put more into what we were doing. That would be impersonation. When the passage talked about art, I thought of my art teacher who would always design all of the sets and made them look so lifelike. When the passage said that there are more behind the stage workers than on stage workers, I knew that that is very true. We had the front and backlighting, the designing people, who cleared the sets and put on new ones, the directing and the building crews. I was able to relate most of the passage through my own past experiences. Chapter 3 talks about "the actor". I found this chapter very interesting. I found out that actors had to go to college too. I also found it compelling to learn that in the passage on page 76, under the picture, it talks about how playing "ordinary people" in a realistic play is often the biggest challenge for an actor.

Gender Stereotyping In The Media Essay

It has been strongly evident that the media has played a large role in gender stereotyping for decades. Since the very beginning of film, movies and television shows have depicted men and especially women as lower or lesser beings. This â€Å"tradition† of sexism has of course, decreased since the 50’s but still lingers on in many of today’s television programs. In the early 50’s, with television shows such as â€Å"I Dream of Jeanie† and â€Å"I Love Lucy, women were portrayed quite openly as being the server to their husbands, the men. They were considered to be lower than men or in other words of less importance. Many of the shows from this era showed a substantial amount of gender stereotyping. For example, the women were to do what they were told, they were the only ones who cooked and cleaned, and they were the primary caregiver for the children. Of course, things have changed since the 50’s. Women have proven to be powerful and just as competent as men, thus, making it harder for television shows to portray them as lesser individuals. However, although the gender stereotyping has decreased, it is certainly still evident in the media. There are several television shows being broadcasted today that do, in fact, show some form of gender stereotyping, particularly towards women. However, it is less out in the open and blunt than it use to be in the early 50’s and 60’s. One must read between the lines and pay attention to notice the stereotypic behavior being portrayed. While this behavior may be subtle, it does, in fact still exist. There is a very well known show on MTV known as â€Å"The Real World,† which comes on every Wednesday. It is a reality based show which places seven strangers into one house for several weeks where they are to live together for the duration of the program. As many of us know, reality shows are not what they appear to be. The directors and producers of such shows have the ability to crop and edit which specific clips of the film that they want to be premiered. Inevitably, they are able to portray the individuals on their show in any way that they want. For example, they may choose to only show clips of certain individuals where they are crying, fighting, or as â€Å"The Real World† often does, being promiscuous. This is a vital key in how this show can stereotype a specific gender. In episode three of the new and current season of â€Å"The Real World,† it can be concluded that women are overall depicted as foolish, whiney, selfish, rude, childish, and promiscuous. The men of the serious, however, are showed in a softer, lighter side. They are portrayed as caring individuals who would rather stay away from most of the women and stray from any drama or arguments going on inside of the house. In one segment of the show, two of the women of the house are running around the house screaming and yelling, playing a game which appears to be cowboys and Indians. The next scene shows the men of the house calmly sitting outside having adult conversations. This is clearly in effort to make the females look childish. In another segment of the show, the women are basically all fighting with one another while the men sit quietly in the background. One of the females sarcastically asks another cast member if it is fun living with a bunch of girls. The other cast member quickly responds with a no. It should be understood that not everything that the women in the house on this show have done have been childish or in anyway degrading. It is impossible to fit everything that has been recorded of these people when producing the show. So, everything that viewers are allowed to see has been carefully selected for various reasons such as higher ratings. The more dramatic events that happen, the more likely it will be for the show to attract audiences. However, why is it that there are no dramatic sequences shown where the men are degrading themselves? In conclusion, gender stereotyping in the media, although lessened since the 50’s, does still exist on television programs today. Whether women are portrayed as inferior to men or simply more ignorant or immature, the fact is that gender stereotyping is an all too sad reality in the world that we live in today. Perhaps one day we can come to an understanding that all men AND women and created equally. Works Cited www. mtv. com www. realworld. com www. people. unt. edu/jw0109/misc/stereotype. htm
