Actions encapsulate a series of editing maneuvers-such as the steps needed to make someone look thinner in a photo or to add zippy captions-in one stroke. This tool, lifted from the professional version of Photoshop, allows you to use prerecorded macros. It amounts to a sophisticated all-in-one extraction and blend tool, and I found it particularly helpful in vacation shots where interlopers kept wandering into my pictures.Īdobe has also added an "action player" to the guided mode. The program seamlessly fills in the empty area using elements of the source image. Essentially, it allows you to eliminate elements of a picture by matching up two similar images, then drawing a line over a person or element in one that you want removed. Adobe has beefed up this feature with a scene cleaner. The previous version of Elements had a photomerge feature that enabled users to combine the best of say, two group shots, and get everyone in the image you want. In guided mode, which is comparable to the How To's in Serif PhotoPlus X2, users get walk-throughs for tasks such as color correction and touching up scratches. The designers have also added a new black-and-white tool that can independently turn specific areas of a photo (say, the background behind a person) monochromatic while leaving the central object in color, but I found the effect more gimmicky than useful. Otherwise, it can be fooled by clouds or irregular horizons filled with trees, which will force you to revert to the old manual mode. The sky effect can work well, assuming the area is well defined. Similarly, a new blue-sky tool allows you to boost washed out skylines by simply drawing a squiggle through the area to pick out the sky for the program. The quick fix section, which lets you make simple corrections, now has a Touch Up panel that includes not just the requisite red-eye remover but some new twists, including a teeth-whitening tool, which does what you'd expect: You roughly outline a smile, and those pearly whites look a bit whiter (keep repeating the process, and you'll create a dazzlingly surreal look).

"I love you too." I said giving him a hug, being careful not to hurt him. "I'll be fine ok? Don't worry just relax, get some rest alright?" I said giving him a warm smile and kissing his forehead. "Your gonna be careful right?" He said in concern. "I'm going to be right back ok? I'm going to go grab that bag full of food." I said finishing the bandages. I blushed when I got close to his bare chest and stomach when I had to wrap the bandages around him. After your able to walk again we're going back up there so no one will notice us. "I have to wrap this around your cut so you won't lose blood and so no dirt will infect it. "The alcohol will help heal it much faster." I said. I spread some around his stomach and he just tried sitting there without moving. "It's gonna sting ok? Take your hands off of the cut." I said. I ran over the bottle of alcohol and cupped some of the alcohol on my hands and slowly walked to him with some dripping off my hands. I tried hard not to blush, or at least not blush too hard to make it noticeable. Why am I making seven seem like sans with a blue jacket and white shirt? That was not suppose to be intended.) He then slowly grabbed the bottom of his shirt and slowly pulling it over his head, revealing his skin and bone body, and placing it in the same place on his jacket. He gave out an annoyed sign and unzipped his jacket and placed it next to him. "I need to pour the alcohol on you and your shirt might seek in! Now hurry up, you might pass out from blood loss." I said demanding. Someone's gonna comment about this aren't they?*waits a few seconds* yeah I thought so. "Seven I know this is weird but you need to take off your jacket and shirt." I said. As I pushed it I quickly got down and first walked over to Seven who was sitting there his back leaning on the huge table leg gripping onto his stomach. When I noticed I had no alcohol I just noticed a bottle of alcohol on the counter and climbed up to push it down. Unfortunately I know we needed some kind of alcohol to make sure the HUGE cut wasn't infected (It's true). I knew this place like the back of my hand, so I knew were all the bandage wraps were. (No I'm not gonna make the joke up top, that's too cliché) he screamed a little every time he took a step. Blood stains on his shirt and jacket he was really hurt. I started to help up Seven as he grasped his stomach because of the cut. <|:Pĭid you guys and gals know Six is 8-12 inches? THE PEOPLE ON THE MAW ARE NOT EVEN TALL! Im so dumb I forgot I already had a cover for this book but forgot about it. The pictures really funny XD and don't worry that not a swear word it says frick :3 or that is, tell meh if it is. People invented "proper" terminology to separate their upper-class sport hunting from what common people did for food rich people and poor people hunted geese, but a poor person probably didn't know that the "proper" term was "skein. Animal group names, like a "skein" of geese or a "pod" of dolphins, comes from hunters hundreds of years ago. It's like how we use different names for animal groups (or "collective nouns") but the history is a lot different. We call lots of baby animals cubs, kits, and kids (including human kids!). Peafowl are called peacocks and peahens, like chickens with "pea" in front. Bulls and Cows can described bovines, elephants, giraffes, and camels. A rooster and a hen do different jobs (chickens), so do stallions and mares (horses).Īfter that we reuse a lot of names for similar groups of animals. It's most common for animals that have important jobs because male bovines and female bovines have different jobs, we call them Bulls and Cows. There isn't really any special reason for the different names that we use, although we can sometimes figure out some explanations. The origin of different animal names in English dates back a really long time. So, we're gonna give you a list of some of the common words for animals of different genders. Some of them can be pretty strange, or they don't get used much you might not hear someone call a turkey a "gobbler," or a ferret a "hob," but those are both real names. Conclusion:ĭeer are graceful and majestic animals, and their collective nouns of herd, drove, gang, and bevy reflect their beauty and strength.In addition to normal animal names, many of the most common animals have different names for male and female animals, and for young ones. Deer are able to swim and can jump over obstacles up to 8 feet high.Deer are social animals and live in small groups.Deer have a highly developed sense of smell and hearing.Deer are herbivores and mainly feed on grass, leaves, and bark.Crias are typically born with all the females of the herd gathering around, in an attempt to. A cria (from Spanish for baby) is the name for a baby llama, alpaca, vicuña, or guanaco. What are llamas babies called Crias Crias. Herd is one of the most common collective nouns for animals. Deer are found in all continents except Antarctica. The collective noun for llamas is a herd of llamas.The bevy of deer was enjoying the sun.The bevy of deer was resting in the shade.The bevy of deer was gathered in the clearing.A Bevy of DeerĪ bevy of deer is used to describe a group of deer that are gathered together in a single area. In this category we discuss all the most used collective nouns used to denote group of different kinds of animals. Collective nouns are a great way to describe a group of animals or things. Flock, pack, and string are the other collective nouns for llamas. However, if you’re in doubt, you can always stick with herd or group. This stems from an English hunting tradition in the Late Middle. The use of nouns of assembly or terms of venery are collective nouns specific to certain kinds of animals. There are many collective nouns that refer to animals. If you see some of them in a group, they might be referred to as a gang or a pack. Collective nouns are the words used to define a group of people, animals or inanimate objects. Buffalo: A gang or an obstinacy of buffalo. The gang of deer was exploring the area. The collective noun for llamas is a herd. Collective Nouns for Mammals Noted for their fur (or hair) and ability to produce milk to feed their young, mammals come in all shapes and sizes. Animal Group Names Mammals A group of bears is called a sloth or sleuth Apes: A shrewdness of apes.The gang of deer was searching for food.This collective noun showcases the affectionate nature of llamas, as if representing a group cuddling together. A 'cuddle' of llamas: Llamas are renowned for their amiability and their propensity to seek out human companionship. The gang of deer was roaming the forest. This collective noun reflects the idea of a gathering of llamas simulating an art exhibition.A Gang of DeerĪ gang of deer is used to describe a group of deer that are roaming together in a wild area. The drove of deer was being guided by a hunter.The drove of deer was being driven by a pack of dogs.The drove of deer was being herded by a shepherd.A Drove of DeerĪ drove of deer is used to describe a group of deer that are being driven or herded by a person or animal. The herd of deer was startled by the loud noise.The herd of deer moved slowly across the field.A Herd of DeerĪ herd of deer is used to describe a large group of deer, usually when they are grazing together in a field. Besides, based on activities, behavior and habitat of deer collective terms like drove, gang, and bevy are used to denote a group of deer. NOUN COLLECTIVE NOUN USAGE EXAMPLE Deer Herd A herd of deer Deer Drove A drove of deer Deer Gang A gang of deer Deer Bevy A bevy of deer Deer Collective Noun What is a group of Deer called?Ī group of deer is called a herd. Drove, gang, and bevy are the other collective names used to denote a group for deer. The team is excited and encouraged by their success the first time out and are ready to compete again. The team would like to thank CDR Schock and 1st Sergeant Sanchez for giving them a chance to compete and have a great time in Moss Park. When the team was finished they got the chance to relax, eat and socialize with other schools that competed that day. These are especially impressive scores since the orienteering team is in its inaugural year. Several Farragut students went on to compete on the Orange course and senior Jason Chen had the fastest time of the day on that course at 62 minutes. Freshman Kenneth Fisher had the fastest time of the day on the Yellow course at 43 minutes and 40 seconds. The 14 competitors competed in two different courses: the Yellow (novice) course and the Orange (intermediate) course. Working as individuals as well as teams, our runners found their way through varying terrain such as marsh, thick bush, saw palmetto, standing water, pine forests, thickets as well as crisscrossing dirt trails. Among these, the oldest and the most popular is foot orienteering, which is what our team competed in on Saturday. Originally a training exercise in land navigation for prep school officers, orienteering has developed many variations. Participants are given a topographical map, usually a specially prepared orienteering map, which they use to find control points. Orienteering is a sport that requires navigational skills using a map and compass to navigate from point to point in diverse and usually unfamiliar terrain whilst moving at speed. On Saturday the 14th of October, Farragut’s newly established Orienteering Team competed in Moss Park, a Florida State Park on the southeastern side of Orlando. Junior Valentina Fornaro Galliano submitted this story about the Orienteering team.

This book could have been really promising but I’m disappointed in it’s unbelievable lack of empathy and its sloppiness in regards to other’s feelings. To me, this comes across less like someone who wants to tell the world who they really are or as an apology to his victims, but as a trophy or to gloat about what he managed to do to others. As someone who is a victim, the way he speaks about his victims in this book is still with such a level of control and manipulation that I find it very difficult to believe he is truly sorry at all. In fact, reading his interactions with Pen felt like I was reliving my experience. I bought this book mainly on a whim but also because I am a victim of the kind of emotional manipulation that he inflicted on the girls in this story. The author comes across, not as someone who once was a narcissist sociopath but as someone who still is. He does this in past tense, but it also seems he still holds many of these opinions, including slut shaming women who swallow. He is clearly very self aware and yet still speaks very degradingly of women throughout this book. I would have appreciated this story a lot more, and would have perhaps really enjoyed it, if he had ever shown any growth. Although this can be forgiven as it’s an autobiography and probably the first publication from this author. The writing style is sloppy and disorganised and makes it very difficult to follow the story. Place it back where you found it - in fact, throw it - and calmly remove yourself from its vicinity before calling the nearest pest control exterminator.Īlthough I see the point of some of the other people in the comments, I have to agree with this article. If at any point in the future you find yourself picking up this book, DO NOT open it. He then moves to Minnesota for two boring years (that to you will feel like two millennia) and falls in love, which leads to a sequence of ridiculous events that attempts to convey the story’s petty message but drastically fails at doing so. Here is what you get to look forward to after that stunning opening line: Our cheeky alcoholic Irish narrator explains, in acute detail, how he inflicts emotional abuse upon women, all the while subjecting you to his paranoiac delusions. “Diary of an Oxygen Thief” truly stays a piece of parasitic, brain-sucking compost for its entirety. No, it does not get better, nor does it employ reverse psychology (as I did in deceiving you to read this article). The likewise anonymous narrator begins by stating, “I like hurting girls” - and if that is not enough to turn you away, I guarantee that one of the next 150 pages certainly will. “Diary of an Oxygen Thief,” self-reported as an autobiography, was published first in 2006 in the Netherlands by an anonymous author. With that disclaimer out of the way, I advise you to maneuver your mouse pointer to the upper left hand corner of the screen (or your finger, if you are on mobile), click that “back” arrow, and peruse some of the other fantastic articles you may find on our website. It is a sick, twisted, crass, lewd, whiny, disorganized, crude, impudent, and entirely inane piece of formless, noxious gelatin that you would probably burn, along with your shoe, if you had stepped in it.

Shallow with a short attention span, once Krillin stated that he was not worthy to be her boyfriend, Maron did not hesitate in accepting another man's offer for a ride without so much as looking back at her former boyfriend, and while she did later return, stating she only loves Krillin, she eventually left with some other boyfriends once she got tired of waiting, and never came back.īiography Dragon Ball Z Garlic Jr. Although largely ignorant of Master Roshi's perverted nature, she did once squeal in shock and considered Roshi "worse" than "the old lady" (referring to Chi-Chi) after the latter briefly groped her. She also has a habit of flirting with other guys while she was dating Krillin, as seen when she makes a flirty comment about Yamcha twice (although in Maron's defense, it's implied she did the first instance because she thought she and Krillin weren't actually dating due to his shy denials when asked) and when she kisses Gohan, although she does show a firm care for Krillin.ĭespite these characteristics, Master Roshi takes a firm liking toward Maron, for "obvious" reasons: her well-defined curved figure and her scanty clothing (along with her blissful ignorance to his perversion for the most part). She also apparently has bad memory recall, as she still seems to be unaware of who Goku is despite Krillin telling her at least 11 times by the time he mentioned him when explaining who Chi-Chi is. In the Japanese version, it's made clear she genuinely didn't understand how rude it sounded, while the English dub had her delivering her comments to Chi-Chi in particular in a more mean-spirited manner. How oblivious she was depended on the language version. Her shallow nature makes it seem like she has no clue when it comes to social graces, as when she refers to Chi-Chi and Bulma as "old ladies"/"middle aged ladies" while seeming completely oblivious as to how rude this sounds. While technically kind in her own right, as she is shown trying to help Gohan repeatedly, Maron is characterized as a bit shallow, as she is shown using her good looks to achieve what she wants. In fact, Korin has trouble trying to read her mind to know her moves during a card game, explaining to Yajirobe: "I've seen party balloons with more on their mind." Maron is air-headed, ditsy, and at times, downright stupid. During the latter portion of her stay at Korin's Tower, she was also seen wearing a short-skirted cheongsam. She also wears a yellow bathing suit for swimming, which is very small. She is commonly seen wearing a bright red dress with low-cut straps, white cuff socks, and white gym shoes, occasionally wearing a green military jacket over it. Maron is a slender young woman of curvaceous frame with long blue hair and blue eyes and large breasts. The toxic mechanism of heavy metals functions in similar pathways usually via reactive oxygen species (ROS) generation, enzyme inactivation, and suppression of the antioxidant defense. High-dose exposure leads to sever responses in animal and human which causes more DNA damage and neuropsychiatric disorders ( Gorini et al., 2014). The toxicity and carcinogenicity of heavy metals are dose dependent. Carcinogenic metals such as arsenic, cadmium, and chromium can disrupt DNA synthesis and repair ( Clancy et al., 2012 Koedrith et al., 2013). While the exact mechanism is unclear, aberrant changes in genome and gene expression are suggested as an underlying process. The fact that several metals have emerged as human carcinogens is another important aspect of the chronic exposure. On the other hand, low-dose exposure is a subtle and hidden threat, unless repeated regularly, which may then be diagnosed by its complications, e.g., neuropsychiatric disorders including fatigue, anxiety, and detrimental impacts on intelligence quotient (IQ) and intellectual function in children ( Mazumdar et al., 2011). High-dose heavy metals exposure, particularly mercury and lead, may induce severe complications such as abdominal colic pain, bloody diarrhea, and kidney failure ( Bernhoft, 2012 Tsai et al., 2017). Simultaneous exposure to two or more metals may have cumulative effects ( Fernandes Azevedo et al., 2012 Cobbina et al., 2015 Costa, 2019 Gazwi et al., 2020). Gastrointestinal and kidney dysfunction, nervous system disorders, skin lesions, vascular damage, immune system dysfunction, birth defects, and cancer are examples of the complications of heavy metals toxic effects. Several acute and chronic toxic effects of heavy metals affect different body organs. They may frequently react with biological systems by losing one or more electrons and forming metal cations which have affinity to the nucleophilic sites of vital macromolecules. Hence, human exposure to metals is inevitable, and some studies have reported gender differences in the toxicity of metals ( Vahter et al., 2007 Tchounwou et al., 2012). Metals among the other environmental pollutants may also occur naturally and remain in the environment. Concentration of heavy metals in water resources, air, and food is assessed with this regard ( Mousavi et al., 2013 Ghorani-Azam et al., 2016 Luo et al., 2020). Food contamination with heavy metals is another concern for human and animal health. Contamination of water and air by toxic metals is an environmental concern and hundreds of millions of people are being affected around the world. Heavy metals have harmful effects on human health, and exposure to these metals has been increased by industrial and anthropogenic activities and modern industrialization. The application of chelation therapy for the management of metal poisoning could be another aspect of heavy metals to be reviewed in the future. Even with the current knowledge of hazards of heavy metals, the incidence of poisoning remains considerable and requires preventive and effective treatment. Defects in DNA repair following the induction of oxidative stress and DNA damage by the three metals have been considered as the cause of their carcinogenicity. Some toxic metals including chromium, cadmium, and arsenic cause genomic instability. Reactions of other heavy metals with certain proteins were discussed as well. The interaction of lead with aminolevulinic acid dehydratase and ferrochelatase is within this context. On the other hand, some of them have selective binding to specific macromolecules. Comparison of the mechanisms of action reveals similar pathways for these metals to induce toxicity including ROS generation, weakening of the antioxidant defense, enzyme inactivation, and oxidative stress. Heavy metals disrupt cellular events including growth, proliferation, differentiation, damage-repairing processes, and apoptosis. Bioaccumulation of these heavy metals leads to a diversity of toxic effects on a variety of body tissues and organs. Acute or chronic poisonings may occur following exposure through water, air, and food. Here, we reviewed the mechanistic action of these heavy metals according to the available animal and human studies. Mercury, lead, chromium, cadmium, and arsenic have been the most common heavy metals that induced human poisonings. The industrial activities of the last century have caused massive increases in human exposure to heavy metals. 2Cardiovascular Disease Research Center, Birjand University of Medical Sciences, Birjand, Iran.1Medical Toxicology and Drug Abuse Research Center, Birjand University of Medical Sciences, Birjand, Iran.Mahdi Balali-Mood 1 Kobra Naseri 1 Zoya Tahergorabi 1 Mohammad Reza Khazdair 2 Mahmood Sadeghi 1* The process involves a detailed analysis of the electrical system and the potential fault currents that could occur. Therefore, it's essential to accurately calculate the arc flash boundary for each piece of equipment to ensure that workers are adequately protected.Ĭalculating the arc flash boundary requires an understanding of the electrical system and the potential hazards associated with it. It's important to note that the arc flash boundary distance can vary depending on several factors, including system voltage, available fault current, and protective device settings. However, the NFPA 70E and CSA Z462 standards provide a table that specifies the minimum arc flash boundary for 480V equipment based on the available fault current and the protective device clearing time.įor example, if the available fault current is 10,000A and the protective device clearing time is 0.1 seconds, the minimum arc flash boundary for 480V equipment is 3 feet for a category 1 PPE level. The arc flash boundary for 480V equipment can vary depending on the incident energy level. The minimum arc flash boundary is the distance from the energized equipment where the incident energy is below 1.2 cal/cm², which is the level of thermal energy that can cause second-degree burns to unprotected skin. The NFPA 70E and CSA Z462 standards provide tables and formulas to help calculate the incident energy and the minimum arc flash boundary distance. The incident energy level is calculated using complex mathematical formulas that consider the system voltage, available fault current, and the time the protective devices take to clear the fault. The minimum arc flash boundary is determined by the incident energy level that could be released in the event of an arc flash. This boundary is marked with a black boundary line and is used to indicate the most hazardous area. Prohibited Approach Boundary (PAB) - The prohibited approach boundary is the closest distance to the energized equipment considered safe for any person to approach, regardless of PPE. This boundary is marked with a red boundary line and indicates the point where a worker must begin wearing the appropriate PPE to prevent injury. Restricted Approach Boundary (RAB) - The restricted approach boundary is the minimum distance from the energized equipment a qualified worker can approach without wearing the appropriate PPE. This boundary is generally marked with a yellow boundary line and is intended to keep unqualified personnel from entering the hazard zone. Limited Approach Boundary (LAB) - The limited approach boundary is the minimum distance from the energized equipment that an unqualified person can approach. There are three arc flash boundaries that are defined by the NFPA 70E and CSA Z462 standards: The NFPA 70E and CSA Z462 standards provide guidance on the minimum distances that should be maintained between energized electrical equipment and workers based on the incident energy levels. The arc flash boundary is the minimum safe distance from the energized equipment that an unqualified worker can approach without wearing PPE. The higher the incident energy, the greater the potential for injury and the larger the arc flash boundary. Incident energy is the thermal energy that could be released during an arc flash, measured in calories per square centimetre (cal/cm²). The arc flash boundary is a critical component of electrical safety programs, as it helps to identify potential danger areas and ensure that workers are aware of the hazards.Īrc flash boundaries are established based on the incident energy that could be released during an arc flash. Implementing an effective arc flash safety program that includes accurate arc flash boundary calculations, appropriate PPE, and specialized training for workers is critical to protect workers from the hazards of arc flash incidents.Īn arc flash boundary is a designated area around energized electrical equipment where an arc flash could cause serious injury or death to a worker not wearing the appropriate personal protective equipment (PPE). |
