Quality of Ball Pen free essay sample

pen A pen (Latin penna, feather) is a writing implement used to apply ink to a surface, usually paper, for writing or drawing. Historically, reed pens, quill pens, and dip pens were used, with a nib dipped in the ink. Ruling pens allow precise adjustment of line width, and still find a few specialized uses, but technical pens such as the Rapidograph are more commonly used. Modern types also include ballpoint, rollerball, fountain, and felt or ceramic tip pens. [l] Contents [hide] * 1 Modern pens * 2 Historic pens * 3 History * 4 Manufacturers * 4. 1 United States * 5 See also * 6 References * 7 External links I [edit] Modern pens The main modern types of pens can be categorized by the kind of writing tip or point: A mark made on paper with a rollerball pen, and the tip of that pen * A ballpoint pen dispenses viscous oil-based ink by rolling a small hard sphere, usually 0. 7- 1. 2 mm and made of brass, steel or tungsten carbide.

The ballpoint pen is usually reliable and inexpensive. [citation needed] It has replaced the fountain pen as the most common tool for everyday writing. * A fountain pen uses water-based liquid ink delivered through a nib. The ink flows from a reservoir through a feed to the nib, then through the nib, due to capillary action and gravity. The nib has no moving parts and delivers ink through a thin slit to the writing surface. A fountain pen reservoir can be refillable or disposable, this disposable type being an ink cartridge. A pen with a refillable reservoir may have a mechanism, such as a piston, to draw ink from a bottle through the nib, or it may require refilling with an eyedropper. Refill reservoirs, also known as cartridge converters, are available for some pens which use disposable cartridges. A fountain pen * A marker, or felt-tip pen, has a porous tip of fibrous material. The smallest, finest- tipped markers are used for writing on paper. Medium-tip markers are often used by children for coloring and drawing. Larger markers are used for writing on other surfaces such as corrugated boxes, whiteboards and for chalkboards, often called liquid chalk or chalkboard markers. Markers with wide tips and bright but transparent ink, called highlighters, are used to mark existing text. Markers designed for children or for temporary writing (as with a whiteboard or overhead projector) ypically use non-permanent inks. Large markers used to label shipping cases or other packages are usually permanent markers. * A rollerball pen dispenses a water-based liquid or gel ink through a ball tip similar to that of a ballpoint pen. The less-viscous ink is more easily absorbed by paper than oil-based ink, and the pen moves more easily across a writing surface. The rollerball pen was initially designed to combine the convenience of a ballpoint pen with the smooth wet ink effect of a fountain pen. Gel inks are available in a range of colors, including metallic paint

Free Essays on Vampirism

Vampires. Blood sucking beast shrieking through the night, or are they more. Vampires are said to be supernatural creatures roaming the night, but they can be much more as you shall see. This brings me to the reason and definition of a "Psychic Vampire". This actually has a double meaning. Satanically speaking, a Psychic Vampire is one who purposely will draw your emotions to them just to make themselves feel good. They will feel sorrow so that you will comfort them or they will show you love just for the purpose of receiving it in return. The second type of Psychic Vampire would be more directed along the line of mysticism and magick. A Psychic Vampire is not one who feeds on blood, but rather one who draws the energy force from their victims body. This can be voluntarily or without knowing it. A person who just seems to wear you out when you are around them would fall into this category. Psychic Vampire can also have malicious intent, but generally there's not much to fear as most are not very proficient and a "psychic draining" is not fatal. These two meaning indeed differ greatly. The first is a more obnoxious, annoying person who deserves a heart of stone to blo ck their worthless attempts. The second, however, is open to the mind of the individual. It's hard to say if this even exists, but many would say it does. If it is a true form of magick then there are ways to protect yourself. Either case, Psychic Vampires exist, so take caution. Actual Vampirism including drinking of blood is a much more different story. I have received various e-mails about people asking me what it is to be a vampire, how blood affects you, and if I personally believe in the many myths and legends. Well, I'll start off with a very simple fact. It is most dangerous to go around pretending to be a story-book vampire when you indeed are not one.

Toumai - Type site of Sahelanthropus tchadensis

Toumai - Type site of Sahelanthropus tchadensis Toumaà ¯ is the name of a late Miocene hominoid who lived in what is today the Djurab desert of Chad some seven million years ago (mya). The fossil currently classified as Sahelanthropus tchadensis is represented by a nearly complete, amazingly well-preserved cranium, collected from the Toros-Menalla locality of Chad by the Mission Palà ©oanthropologique Franco-Tchadienne (MPFT) team led by Michel Brunet. Its status as an ancient hominid ancestor is somewhat in debate; but Toumaà ¯s significance as the oldest and best preserved of any Miocene age ape is undeniable. Location and Features The Toros-Menalla fossil region is located in the Chad basin, a region that has fluctuated from semi-arid to wet conditions over and over again. The fossil-bearing outcrops are in the center of the northern sub-basin and consist of terrigenous sands and sandstones interbedded with argillaceous pebbles and diatomites. Toros-Menalla is some 150 kilometers (about 90 miles) east of the Koro-Toro locality where Australopithecus bahrelghazali was discovered by the MPFT team. Toumaà ¯s skull is small, with features suggesting it had an upright stance and used bipedal locomotion. Its age at death was approximately 11 years old, if comparisons to wear on the teeth of modern chimpanzees are valid: 11 years is an adult chimpanzee and it is assumed that so was Toumaà ¯. Toumaà ¯ has been dated to approximately 7 million years of age using the Beryllium isotope 10Be/9BE ratio, developed for the region and also used on the Koro-Toro fossil beds. Other examples of S. tchandensis were recovered from Toros-Menalla localities TM247 and TM292, but were limited to two lower jaws, the crown of a right premolar (p3), and one partial mandible fragment. All hominoid fossil materials were recovered from an anthracotheriid unitso called because it also contained a large anthracotheriid, Libycosaurus petrochii, an ancient hippopotamus-like creature. Toumaà ¯s Cranium The complete cranium recovered from Toumaà ¯ had suffered fracturing, displacement and plastic deformation over the past millennia, and in 2005, researchers Zollikofer et al. published a detailed virtual reconstruction of the skull. This reconstruction illustrated in the photo above used high-resolution computed tomography to create a digital representation of the pieces, and the digital pieces were cleaned of adhering matrix and reconstructed. The cranial volume of the reconstructed skull is between 360-370 milliliters (12-12.5 fluid ounces), similar to modern chimpanzees, and the smallest known for an adult hominid. The skull has a nuchal crest that is within the range of Australopithecus and Homo, but not chimpanzees. The skulls shape and line suggests Toumaà ¯ stood upright, but without additional postcranial artifacts, thats a hypothesis waiting to be tested. Faunal Assemblage Vertebrate fauna from TM266 include 10 taxa of freshwater fish, turtles, lizards, snakes and crocodiles, all representatives of ancient Lake Chad. Carnivores include three species of extinct hyenas and a saber toothed cat (Machairodus cf. M giganteus). Primates other than S. tchadensis are represented only by a single maxilla belonging to a colobine monkey. Rodents include mouse and squirrel; extinct forms of aardvarks, horses, pigs, cows, hippos and elephants were found in the same locality. Based on the collection of animals, the TM266 locality is likely to be Upper Miocene in age, between 6 and 7 million years ago. Clearly aquatic environments were available; some of the fish are from deep and well-oxygenated habitats, and other fish are from swampy, well-vegetated and turbid waters. Together with the mammals and vertebrates, that collection implies that the Toros-Menalla region included a large lake bordered by a gallery forest. This type of environment is typical for the most ancient of hominoids, such as Ororrin and Ardipithecus; in contrast, Australopithecus lived in a wider range of environments including everything from savannah to forested woodlands.

Hawley Harvey Crippen Case - Research Paper Example This is also considered as the first case Bernard Spilsbury, the renowned pathologist investigated. Radio was used for the tracking of the criminals; this was strange in that period. Advocates who cry for the abolition of death penalty gives the case of Crippen as an example for the wrongfully convicted cases. However, Dr Crippen’s conviction is not considered false by many people. The wife of Doctor Hawley Crippen was found missing when Crippen maintained affair with another woman.

Belle was tired of her husband. She was aware of his relationship with Ethel le Neve. She threatened that she would leave Crippen. This news must have been happy for him. But she wanted their joint savings to be taken with her. As per the records, on in December 1909, she submitted notice for the withdrawal of the money in the bank.

Camping †My Only Refuge :: Personal Narrative Writing

Camping – My Only Refuge Every night when I lie down to sleep, I can hear the continuous, buzzing echo of the day's residue. The cacophony of sound that gets trapped in my head all day long begins its slow release: the ringing of phones like calculated screams, the falling of fingers on key boards like pelting leaden raindrops, people barking orders at me as if they were the only masters I am obliged to serve. The faces of these monsters I see in my mindwarped and twisted, still yelling, demanding, screeching. They circle around and taunt me. It is guilt that makes it so my eyes are wide and bloodshot while my mind throbs and my body aches for sleep. I should stay awake longer. . .there is more I can accomplish, more work to be done. I can push myself just a little bit moreand I should. A go-getter wants more from herself than others expect, and the monsters are an ample challenge; they're insatiable. There is a fun house in my mind and all I want to do is sleep. Every day my alarm sounds, my eyes crack open. I throw the covers off and feel the surge of frigid air, tired and grumpy and cursing the day for its fast arrival. It seems as if I never slept...all my days are like those before them, separated only by the nightmares that mirror them. My body craves a shower but the clock on the wall says "No." I gather together the assignments that kept me up well past the change of day and hope they are as good as they seemed at 3:45 a.m. My stomach rumbles with indigestion from the 2 a.m. pepperoni and olive pizza. I grab a stale but clammy slice from the card board box on the floor and head out the door. This is the start that propels me into my day. By 7:30 am I am roaming the streets, video camera in hand, searching for the latest news. It is my job to pry into miserable people's lives to disclose the boring facts about their boring lives. And they get frustrated and angry with me? Deadline is 11:30, but my six-hour class marathon begins at 10:00; at best I'm allotted two and a half hours to film, script, and edit a news package for the class that will make or break me as a broadcast journalism major.
