    Full Text Available The art of body piercing is ancient; however, nowadays it has evolved into a fashion statement. In the Indian subcontinent, ear and nose piercing hold religious and cultural significance in addition to being done for aesthetic reasons. Body piercing is routinely performed by railroading technique or by piercing guns; many modifications of the technique have emerged. Irrespective of the technique used, the main complications associated are intraoperative bleeding and postoperative infection. To overcome these problems, we describe a novel and simple technique of ear and nose piercing using the radio frequency cautery.

    Although body piercing procurement continues to increase, 13% to 18% of them are removed. Reasons for piercing removal in college students were examined with three groups: (a) those who kept all their piercings, (b) those who removed some, or (c) those who removed all of their body piercings. Of the sample, 41% were still pierced; 50% in their lifetime. Their major purpose for the body piercing was "helped them feel unique." Females obtained more (in high school) and then removed more, usually as upperclassmen. Males and females reported themselves as risk takers at procedure time and currently; however, only 10% cited deviancy as a reason for the body piercing(s). Only removal elements of "I just got tired of it" and "I just decided to remove it" were present, especially with the Some Removed Group. Further examination of body piercing building personal distinctiveness and self-identity to promote their need of uniqueness is suggested.

    Body modifications such as piercings, tattoos and surgery have increased in popularity in recent times and have become more socially acceptable. The common complications of piercing different parts of the human anatomy are well-documented, including sepsis, allergic reactions and, more rarely, endocarditis and ischaemia. Deaths related to piercing complications are primarily septic in origin. In this case, a man in his 50s died due to complications of his multiple umbilical piercings. The cause of death was unusually linked to body modification; the umbilical piercings had ultimately led to a mesenteric infarction. Cases such as these are forensically important due to potential manslaughter charges that could be brought against a piercing establishment. More importantly, this case highlights another extreme complication of body modification. Fashion statements are always changing and impact upon many lives. It is important to highlight to people the potentially life-threatening complications of common piercing practices.

    Body and earlobe piercing are common practices in the USA today. Minor complications including infection and bleeding occur frequently and, although rare, major complications have been reported. Healthcare professionals should be cognizant of the medical consequences of body piercing. Complications vary depending on the body-piercing site, materials used, experience of the practitioner, hygiene regimens, and aftercare by the recipient. Localized infections are common. Systemic infections such as viral hepatitis and toxic shock syndrome and distant infections such as endocarditis and brain abscesses have been reported. Other general complications include allergic contact dermatitis (e.g. from nickel or latex), bleeding, scarring and keloid formation, nerve damage, and interference with medical procedures such as intubation and blood/organ donation. Site-specific complications have been reported. Oral piercings may lead to difficulty speaking and eating, excessive salivation, and dental problems. Oral and nasal piercings may be aspirated or become embedded, requiring surgical removal. Piercing tracts in the ear, nipple, and navel are prone to tearing. Galactorrhea may be caused by stimulation from a nipple piercing. Genital piercings may lead to infertility secondary to infection, and obstruction of the urethra secondary to scar formation. In men, priapism and fistula formation may occur. Women who are pregnant or breastfeeding and have a piercing or are considering obtaining one need to be aware of the rare complications that may affect them or their child. Though not a 'complication' per se, many studies have reported body piercing as a marker for high-risk behavior, psychopathologic symptoms, and anti-social personality traits. When it comes to piercing complications, prevention is the key. Body piercers should take a complete medical and social history to identify conditions that may predispose an individual to complications, and candidates should choose a

    Full Text Available Configurando uma experiência física que desafia tabus físicos e sociais, a marcação do corpo através da tatuagem e body piercing tem sido bastante explorada no espaço público mediatizado em função das questões da dor voluntária e dos riscos de saúde individual e pública implicados. Ao pânico moral que já envolvia estas práticas, associadas a comportamentos tidos como socialmente desviantes, psico-patológicos ou criminosos, junta-se-lhes outra espécie de pânico social, o «pânico higienista», associado ao receio de contrair doenças infecto-contagiosas, ou de reagir aos materiais ou tintas encarnados. No sentido de ir além destes discursos, este artigo pretende analisar: por um lado, como os consumidores actuais de tatuagem e body piercing lidam com a dor que lhe está associada, que emoções enquadram essa sensação e que estratégias convocam no seu controlo; por outro lado, como é que os produtores de tatuagem e body piercing, perante novas e mais alargadas clientelas, lidam com exigência de disciplinas sanitárias na sua prática profissional. Em termos metodológicos, a informação empírica apresentada no artigo foi obtida em situação de entrevista em profundidade, de natureza biográfica, semi-estruturada na sua preparação e semi-diretiva na sua aplicação, a portadores de corpos multitatuados e multiperfurados, profissionais ou apenas consumidores de tatuagem e body piercing.

    To describe the knowledge, attitudes, and practices of young adults toward body piercing. An anonymous 30-item survey was given to 103 undergraduate students at the campus health service of a large urban university. The questionnaire collected data on students' perceptions regarding the social acceptability of body piercing, their experiences with and attitudes toward this form of body art, and their knowledge of associated health risks. One hundred (97%) out of the 103 surveys distributed had sufficient data for analysis. Fifty-six percent of participants (age range, 17 to 25 years) reported having a body piercing at one time. Participants with a piercing were more likely to have a tattoo (OR, 4.13; 95% CI, 1.10-15.56; P=.04). The majority of participants (65 [78%]) reported "liking" body piercing on others, though a smaller percentage (45 [52%]) reported "liking" it on themselves (z=3.58, Part is acceptable on others, they feel it is less acceptable on themselves. Study participants displayed a high level of awareness regarding the potential health risks of body art, and, in fact, overestimate those risks. Implications for patient education are addressed.

    This study assessed tattoos and body piercings as markers of risk-taking behaviors in adolescents. A 58-question survey, based on the 1997 Centers for Disease Control and Prevention Youth Risk Behavior Survey, was offered to all adolescent beneficiaries that came to the Adolescent Clinic. The survey contained standard Youth Risk Behavior Survey questions that inquire about eating behavior, violence, drug abuse, sexual behavior, and suicide. Questions about tattoos and body piercings were added for the purposes of this study. Participants with tattoos and/or body piercings were more likely to have engaged in risk-taking behaviors and at greater degrees of involvement than those without either. These included disordered eating behavior, gateway drug use, hard drug use, sexual activity, and suicide. Violence was associated with males having tattoos and with females having body piercings. Gateway drug use was associated with younger age of both tattooing and body piercing. Hard drug use was associated with number of body piercings. Suicide was associated with females having tattoos and younger age of both tattooing and body piercing. Tattoos and body piercings were found to be more common in females than males. Tattoos and/or body piercings can alert practitioners to the possibility of other risk-taking behaviors in adolescents, leading to preventive measures, including counseling. Tattoo and body piercing discovery should be an important part of a health maintenance visit to best direct adolescent medical care.

    Postmodern perspectives of body piercing and tattooing interpret these as signifiers of the self and attempts to attain mastery and control over the body in an age of increasing alienation. In this exploratory study, 79 adolescent females, ages 15 to 18 (M = 16.08, SD = 1.36), completed the Coopersmith Self-Esteem Inventory (SEI; Coopersmith, 1981), the Beck Depression Inventory (BDI; Beck, 1978), the Body Investment Scale (BIS; Orbach & Mikulincer, 1998), and the State-Trait Anger Expression Inventory (STAXI-2; Spielberger, 1996). Analyses revealed that body piercings and tattoos were significantly correlated with trait anger (Angry Reaction subscale scores). A multiple regression analysis indicated that three of the dependent variables (Trait Anger-Reaction, BDI, and Feeling subscale of the BIS) were predictors of the total number of body piercings and tattoos.

    Some research suggests adorning the body with tattoos or piercing jewelry is normative. Survey data were gathered from 450 undergraduates (72% female; 80% Euro-American; 63% freshmen and sophomores). Correlations between an index of respondents' religious belief and practice and their attitudes toward individuals who had more body piercings were weak if piercings were 7 or more, including piercings of the nipples and genitals. As religiosity is a carrier of normative behavior, individuals who have body piercings may be viewed as behaving within cultural norms.

    This study evaluated patients' perceptions of patient care providers with visible tattoos and/or body piercings. As tattooing and body piercing are increasingly popular, research that informs nursing administrators regarding policies on patient care providers having visible tattoos and body piercings is warranted. A total of 150 hospitalized adult patients compared pictures of male and female patient care providers in uniform with and without tattoos and/or nonearlobe body piercings. Patient care providers with visible tattoos and/or body piercings were not perceived by patients in this study as more caring, confident, reliable, attentive, cooperative, professional, efficient, or approachable than nontattooed or nonpierced providers. Tattooed female providers were perceived as less professional than male providers with similar tattoos. Female providers with piercings were perceived as less confident, professional, efficient, and approachable than nonpierced female providers. Nursing administrators should develop and/or evaluate policies regarding patient care providers with visible tattoos and/or body piercings.

    Little is known about the prevalence and consequences of body art application. Our aim was to provide US tattooing and body piercing prevalence, societal distribution, and medical and social consequence data. Random digit dialing technology was used to obtain a national probability sample of 253 women and 247 men who were 18 to 50 years of age. Of our respondents, 24% had tattoos and 14% had body piercings. Tattooing was equally common in both sexes, but body piercing was more common among women. Other associations were a lack of religious affiliation, extended jail time, previous drinking, and recreational drug use. Local medical complications, including broken teeth, were present in one third of those with body piercings. The prevalence of jewelry allergy increased with the number of piercings. Of those with tattoos, 17% were considering removal but none had had a tattoo removed. This was a self-reported data set with a 33% response rate. Tattooing and body piercing are associated with risk-taking activities. Body piercing has a high incidence of medical complications.

    The purpose of this paper is to report the findings of a study exploring factors associated with female and male intimate body piercing, with particular emphasis on health issues. Nipple and genital piercings (intimate piercings) have become common types of body art. Scant medical and nursing literature is available, leading to little understanding of these body modifications by health care providers. A convenience sample of intimately pierced individuals (63 women and 83 men) from 29 states in the United States of America was surveyed via an author-developed questionnaire. Questions focused on demographic characteristics, decision factors and health problems related to intimate piercings. Self-reported characteristics were compared between female and male participants, and participants were compared demographically to United States general population. Participants reported wearing nipple piercings (43%), genital piercings (25%) and both types (32%). Respondents were significantly younger, less ethnically diverse, better educated, less likely to be married, more often homosexual or bisexual and they initiated sexual activity at a younger age than the US population. Deliberate, individual decisions for procurement of the intimate piercings were made. Average purchase consideration was at age 25 (nipple) and 27 (genital); average age to obtain the piercing was 27 (nipple) and 28 (genital) years. Purposes for obtaining the piercings included uniqueness, self-expression and sexual expression. Most participants still liked their piercing (73-90%). Health concerns related to intimate piercings were described by both those with nipple piercings (66%) and with genital piercings (52%) and included site sensitivity, skin irritation, infection and change in urinary flow (male genital). Few STDs (3%) were reported and no HIV or hepatitis. Usually non-medical advice was sought for problems -- often from the body piercer. Understanding client rationale is not a necessary

    Body piercing, which is prevalent in young adults, has been suggested to be associated with features usually related to posttraumatic stress disorder (PTSD) such as high-risk behaviours and psychopathological symptoms and might be motivated by a wish to deal with prior traumatic experiences. However, to date, no research has investigated the relationship between this practice and PTSD symptoms. The present research aims to investigate the possible relationship between body piercing and PTSD symptoms in French-speaking young adults. According to our results, having two or more body piercings was associated with a twofold increased risk for scoring above the cut-off score for PTSD on the PTSD checklist. Our findings suggest that two or more body piercings might serve as an identifiable marker for PTSD symptoms and may have important implications for clinical screening.

    Though the popularity of body modification increases, psychosocial data about practitioners of body piercing and tattooing are few and controversial. Most studies used semi-structured interviews and relatively small sample sizes. The aim of this study was to explore psychosocial background information (motivation, sexual abuse) for body modification practises based on a sufficiently large sample. A core group of 432 subjects with body piercings and/or tattoos (readers of a specialised magazine on body modification; mean age: 28 years) was investigated in this study using a 55-item questionnaire. The mean number of body modifications (piercings and tattoos) was nine. Participants with a history of sexual abuse and high users with more than 10 body modifications differed from those without these features with respect to several motivations and consequences of body modification. Participants with sexual abuse often stated that they wanted to overcome certain experiences, and high users were characterised by the feeling of an addiction to continue body modification. Clinicians should include questions on body modifications and their motives in anamnestic schedules. Copyright © 2011 Elsevier Ltd. All rights reserved.

    A case report. We report septic shock as postoperative complication following an instrumented posterior spinal arthrodesis on a patient with multiple body piercings. The management of this potentially catastrophic complication and outcome of treatment is been discussed. Body piercing has become increasingly more common because of change in culture or as a fashion statement. This has been associated with local or generalized ill effects including tissue injury, skin and systemic infections, and septic shock. There is no clear guideline pathway regarding removal and reinsertion of body piercings in patients who undergo major surgery. Complications following orthopedic or spinal procedures associated with body piercing have not been reported. We reviewed the medical notes and radiographs of an adolescent patient with Scheuermann kyphosis and multiple body piercings who underwent a posterior spinal arthrodesis and developed septic shock. Septic shock developed on postoperative day 2 after reinsertion of all piercings following the patient's request. The patient became systemically very unwell and required intensive medical management, as well as a total course of antibiotics of 3 months. The piercings remained in situ. She did not develop a wound infection despite the presence of bacteremia and spinal instrumentation. The patient had no new piercings subsequent to her deformity procedure. Two and a half years after spinal surgery she reported no medical problems, had a balanced spine with no loss of kyphosis correction and no evidence of nonunion or recurrence of deformity. The development of septic shock as a result of piercing reinsertion in the postoperative period has not been previously reported. This is an important consideration to prevent potentially life-threatening complications following major spinal surgery.

    Can it be said that body piercing is ubiquitous, found across all socioeconomic groups? The major concentration is among adolescents and young adults 15 to 30 years old, in some studies, 50% of the population. Commonly identified physical risks are bleeding, tissue trauma, and bacterial infections; psychosocial risks are unhappiness, low self-esteem, and disappointment. The Health Belief Model is used to explain decision making; purposes for body piercing consistently center on personal expression (self-identity) and uniqueness. The international and US body piercing regulations are discussed, leading to the need for tracking complications globally and standardization of regulations. Proactive health education for clients and health providers remains a priority.

    Body piercing, a type of body modification that is practiced in many cultures, creates an unnatural tract through tissue that is then held open by artificial means. Today, professional body piercing is often performed in piercing establishments that are subject to dissimilar forms of regulation. The most frequently reported medical complication of body piercing and similar body modifications, such as dermal implantation, is infection. Patients with piercings who undergo surgery may have additional risks for infection, electrical burns, trauma, or airway obstruction. The published research literature on piercing prevalence, complications, regulations, education, and nursing care is outdated. The purpose of this article is to educate nurses on topics related to nursing care for patients with piercings and similar body modifications, including the history, prevalence, motivations for, and perceptions of body piercings as well as possible complications, devices used, locations, healing times, regulations, patient education, and other health concerns.

Reasons for obtaining body art include need for individual expression and peer support. Techniques for tattooing are advancing, along with development of newer inks that may be less reactive. When patients become tired of their body art, or develop complications from the art itself, removal needs to be considered. Newer laser modalities may provide tattoo removal options with less scarring potential.

    Full Text Available Piercings (body art, i.e. with jewelry are more and more widespread. They can induce various complications such as infections, allergies, headaches, and various skin, cartilage, or dental problems which will lead to economic effects on health-care systems. We draw attention to other possible side effects resulting from face piercing complications such as eye misalignment, decreased postural control efficiency, and nonspecific chronic back pain. We found that the origin was pierced jewelry on the face. Removing the jewelry restored eye alignment, improved postural control, and alleviated back pain in a lasting way. This observation is important for health; further investigations would be of interest.

    The present paper addresses the psychological impact of body modifications (e.g. tattoos, body piercing and esthetic genital plastic surgery) on the sexual health of individuals and refers to past and present research insights. Body modifications are understood as invasive interventions on the human body, especially interventions on the human skin which result in (semi-)permanent changes. Tattoos and body piercing (in particular genital piercing) positively affect the sexual satisfaction and the sexual appeal of men and women but there is a controversial association with high risk sexual behavior. Moreover, this article focuses on esthetic genital plastic surgery based on the increasing interest and insights of the impact on female genital self-perception and sexual behavior.

    Piercings (body art, i.e., with jewelry) are more and more widespread. They can induce various complications such as infections, allergies, headaches, and various skin, cartilage, or dental problems, and represent a public health problem. We draw attention to possible side effects resulting from face piercing complications observed on four young adults such as eye misalignment, decreased postural control efficiency, and non-specific chronic back pain with associated comorbidity. We found that the origin was pierced jewelry on the face. Removing the jewelry restored eye alignment, improved postural control, and alleviated back pain in a lasting way. We suggest that pierced facial jewelry can disturb somaesthetic signals driven by the trigeminal nerve, and thus interfere with central integration processes, notably in the cerebellum and the vestibular nucleus involved in postural control and eye alignment. Facial piercings could induce sensory–motor conflict, exacerbate, or precipitate a pre-existing undetermined conflict, which leads pain and complaints. These findings are significant for health; further investigations would be of interest. PMID:21960975

    Full Text Available Abstract Background The practice of tattooing and piercing has expanded in western society. In order to verify young adults' knowledge of the risk and practices related to body art, an investigation was conducted among freshmen of the University of Bari in the region of Apulia, Italy. Methods The study was carried out in the Academic Year 2009-2010 through an anonymous self-administered written questionnaire distributed to 1.656 freshmen enrolled in 17 Degree Courses. Results Of the 1.598 students included in the analysis, 78.3% believe it is risky to undergo piercing/tattoo practices. AIDS was indicated as a possible infection by 60.3% of freshmen, hepatitis C by 38.2%, tetanus by 34.3% and hepatitis B by 33.7% of the sample. 28.1% of freshmen were not aware that there are also non-infectious complications. 29% of the sample had at least one piercing or tattoo (this percentage does not include earlobe piercing in women. Of those with body art, the decision to undergo body art was made autonomously in 57.9% of the participants. 56.3% of freshmen undergoing body art had taken less than a month to decide. With regard to the reasons that led the sample to undergo body art, 28.4% were unable to explain it, 23.8% answered to improve their aesthetic aspect, 18.4% to distinguish themselves from others, 12.3% for fashion; 17.1% for other reasons. 25.4% of the sample declared that they had a piercing (79.8% female vs 20.2% male; ratio M/F 1:4.0. The average age for a first piercing was 15.3 years (range 10-27; SD ± 2.9. 9.6% of the sample declared that they have a tattoo (69.9% female vs 30.1% male; ratio M/F 1:2.3. The average age for a first tattoo was 17.5 years (range 10-26, SD ± 2.4. Conclusions Most of the freshmen knew about AIDS-related risks but not other potential risks. Body art is fairly common among young adults (especially women. The decision is often not shared with the family and is undertaken mostly without a specific reason or for the

    The study aimed to investigate the motivations underlying the body modification practices of tattooing and piercing. There were 80 participants recruited from an Australian music store, who provided descriptions of their tattoos and piercings and completed measures of need for uniqueness, appearance investment and distinctive appearance investment. It was found that tattooed individuals scored significantly higher on need for uniqueness than non-tattooed individuals. Further, individuals with conventional ear piercings scored significantly lower on need for uniqueness than individuals with no piercings or with facial and body piercings. Neither appearance investment nor distinctive appearance investment differed significantly among tattoo or piercing status groups. Strength of identification with music was significantly correlated with number of tattoos, but not number of piercings. It was concluded that tattooing, but not body piercing, represents a bodily expression of uniqueness. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Buddhist tantric practitioners embrace the liminal status of the human body to manifest divine identity. In piercing to the pith of human embodiment, the tantric practitioner reconfigures the shape and contours of his/her reality. This article investigates the evolution of one particular technique for piercing to the pith of the body on Tibetan soil, a ritual practice known as body mandala [lus dkyil Skt. deha-maṇḍala]. In particular, it uncovers a significant shift of emphasis in the application of the Guhyasamāja body mandala practice initiated by champions of the emerging Gandenpa [Dga’ ldan pa] or Gelukpa [Dge lugs pa] tradition of Tibetan Buddhism, Tsongkhapa (1357–1419 and Mkhas grub rje (1385–1438. This article reveals some of the radical implications of ritual exegesis, ranging from the socioreligious aspects of securing prestige for a tradition to the ultimate soteriological goals of modifying the boundaries between life and death and ordinary and enlightened embodiment.

    Body piercing (BP) is defined as penetration of jewellery through the skin. Along with tattooing BPs are the most common body modifications. Complications related to piercing are numerous. They can be acute or chronic, infectious or non infectious and local or systemic complications. Acute infections constitute the most important complications and occur independently of the piercing site. Special attention should be brought on oral piercings, as they are frequent and responsible for numerous complications. A non-judgmental approach is recommended, when a pierced patient seeks medical help for a piercing complication or any other health issue.

    At present tattoos and piercings can no longer be regarded as destructive acts of self mutilation practized by fringe groups. Body modifications (BMs) are found in virtually all preindustrial cultures and have their roots in ancient myths and magical rituals. The prevalence of tattoos and piercings in the German population is 8.5% and 6.8%, respectively. Unemployed young men and young women who do not live in a firm partnership show particularly high prevalences. The incidence of BMs correlates positively with the personality trait "sensation seeking", particularly in young women. BMs often serve to express individuality and identity, and they also reflect changed attitude towards the human body and body art as well as following fashion trends. However, BMs can also provide valuable diagnostic indications for identity search and risk taking behaviour.

    Full Text Available Body piercing has been practiced for thousands of years all over the world for beautification, religion, initiation rites or status reasons. Genital piercings also have a significant background and have been practiced for enhancing sexual pleasure, chastity, shocking or as a protest against a conservative society. As the popularity of genital piercings increased in the last years, the number of complications is also on the rise. It is therefore important for the medical professionals to have at least basic knowledge regarding this practice, as it might be required in the management of unpredictable complications.

    Previous studies have found a link between body tattoos or piercings and risky behavior. However, these studies only examined survey data but not real behavior. Young men (mean = 20.6 years) and women (mean = 20.2 years) leaving a bar were asked whether they wore tattoos and piercings or not and were requested to breathe into a breathalyzer in order to evaluate their alcohol consumption. It was found that participants with piercings and/or tattoos as well as combined piercings and tattoos revealed higher levels of alcohol consumption. Piercings and tattoos could serve as signs of alcohol consumption for educators, parents, and physicians. Copyright © 2012 by the Research Society on Alcoholism.

    Body piercing has gained tremendous popularity since the mid nineties. Genital piercings constitute a peculiar variant of piercing due to its sensitive localization. Health care providers are often very little informed about those piercings. Besides, negative stereotypes are often attributed to the bearers of such piercings. This review focuses not only on the medical aspects of genital piercings but also on the social, cultural and psychological background that surround those piercings.

    Tatoos and piercing, though they might appear as something like a trend, if not a craze, remain for a majority minority and even fringe practices. For the adolescent, questing for his identity (no more a child, not yet an adult), the tegmental sign is a way of engraving in the flesh dramatic events of his existence. The body mark is a search for independence, a symbolic attainment of self-reliance, a way of severing the umbilical cord and of asserting oneself. In face of a life no longer under control, the body is an object at hand, on which self-will is almost unbridled... These body modifications testify to change.

    Piercing of the tongue and perioral regions is an increasingly popular expression of body art, with more patients coming in for a routine check-up with tongue and/or lip piercings. Several complications of oral piercing have been reported, some of which are life-threatening. In the present clinical survey the prevalence of both tongue and lip piercing complications in oral health was assessed in a group of 50 patients. The most common dental problem registered was chipping of the teeth, especially in association with tongue piercing. Gingival recession was seen as a result of lip piercing with studs. Post-procedural complications included oedema, haemorrhage and infection. Therefore, dentists and oral and maxillofacial surgeons should be given more authority to advise patients with oral and facial piercings or those who plan to acquire this type of body art.

    Following a cluster of serious pseudomonas skin infections linked to a body piercing and tattooing premises, a look-back exercise was carried out to offer clients a screen for blood-borne viruses. Of those attending for screening 72% (581/809) had a piercing procedure in the premises of interest: 94 (16%) were under 16 years of age at the time of screening. The most common site of piercing was ear (34%), followed by nose (27%), nipple (21%) and navel (21%). A small number (<5) tested positive for hepatitis B and C, with no evidence this was linked to the premises. However, 36% (211/581) of clients reported a skin infection associated with their piercing. Using data from client forms, 36% provided a false age. Those aged under 16 years (OR 4.5, 95% CI 2.7-7.7) and those receiving a piercing at an intimate site (OR 2.1, 95% CI 1.3-3.6) were more likely to provide a false age. The findings from this exercise were used to support the drafting of the Public Health (Wales) Bill which proposed better regulation of piercing premises and the need to provide proof of being 18 years of age or over before having a piercing of an intimate site.

    The new legal regulations and agreements dealing with the type of locales and personnel authorized to implant body rings through pierced holes known popularly as piercings brings with it the need for nurses to learn about this practice and to adapt our habitual sanitary techniques, in an urgent manner, in order to cover the increasing aesthetic demand. The nursing profession needs to amplify its range of treatments for this piercing practice so it is not limited to merely inserting rings or studs in holes.

    Piercings and tattoos have become very popular in western society in recent decades, particularly among younger generations. Reports of medical complications associated with these decorative techniques have increased in parallel with the rise in their popularity. Due to their high frequency, adverse cutaneous reactions are particularly important among these potential complications. Tattoo-related complications include a number of cutaneous and systemic infections secondary to breach of the epidermal barrier, acute and delayed inflammatory reactions with different histopathological patterns, the appearance of benign and malignant tumors on tattooed areas of skin, and certain dermatoses triggered by isomorphic phenomena. Piercing-related complications are similar, though some, such as pyogenic skin infections, are much more common due to the delayed wound healing after piercing in certain sites. We must differentiate between complications that are independent of the site of piercing, and specific complications, which are closely related to the body area pierced. The rate of complications after performing piercings or tattoos depends on the experience of the artist, the hygiene techniques applied, and the postprocedural care by the customer. However, some of these complications are unpredictable and depend on factors intrinsic to the patient. In this article, we review the most common decorative techniques of body art, with particular focus on the potential cutaneous complications and their management.

    To identify the advice given by piercing parlours prior to orofacial piercing and to determine how many dental practitioners see complications from orofacial piercings. Administered questionnaire to 19 piercing parlours and postal questionnaire to 400 dental practitioners in south-east Wales. Ninety-nine per cent of 227 dental practitioners in south-east Wales had treated patients with orofacial piercings, over three-quarters had seen a patient for a complication caused by the piercing, and over half (N=120) had treated a patient for a complication of piercing. Tongue (N=225) and lip (N=209) piercings were most frequently seen and the most commonly occurring complication was fractured or cracked teeth (N=176). Almost all practitioners wanted more information on orofacial piercing and its sequelae. All 19 piercing parlours in south-east Wales warned clients about pain following piercing and 18 mentioned swelling; only four discussed possible damage to teeth and none discussed the risk of airway obstruction. Despite the concerns of dental and medical professionals orofacial piercing remains popular and the complications it causes are frequently seen by dental practitioners. There is a need for literature to assist both dental practitioners and piercers in advising and safeguarding patients.

    Literature on hyperprolactinemia in the setting of a nipple piercing is limited to individuals with concomitant breast/chest wall infection. It is unclear if chronic nipple stimulation from a piercing alone can cause sustained elevations of serum prolactin. Nipple piercing is emerging as a more mainstream societal form of body art, and the answer to this clinical question would potentially alter patient management. Our aim was to assess serum prolactin levels in subjects with nipple piercing. Inclusion criteria were as follows: men and women ≥ 18 years old with nipple piercing(s) present > 6 months. Exclusion criteria included: women who are pregnant, lactating or men and eight women were enrolled. Median (range) ages for men and women were 33 (24-42) and 27 years (23-42), respectively. All except one subject had bilateral piercings. The median interval from nipple piercing to blood draw was 4.0 (2.0-12.0) years. None of the subjects had hyperprolactinemia. Median (range) prolactin levels for men and women were 5.6 ng/mL (3.8-7.4) and 8.0 ng/mL (2.8-10.9), respectively. Our results suggest that in the absence of any concomitant infection, chronic nipple piercing is not associated with hyperprolactinemia.

Women with borderline symptomatology were compared to women without borderline symptomatology concerning the extent of and motives for body modification.The 2 groups showed no differences in regard to amount and extent of body modifications. The "borderline"-group considered individuality, coping and management of negative life-events to be more crucial reasons for body modification than the non-borderline females.The degree of a person's body modification is not a feasible indicator for psychopathological strain. Though, for people with borderline tendency body modification may serve as a coping strategy similar to self-injury. © Georg Thieme Verlag KG Stuttgart · New York.

    Oral piercings have a long history as part of religious, cultural, or sexual symbolism in many traditional tribes; currently, these ornaments have wide acceptance among young people. Several oral and systemic complications may be associated with this practice; however, limited data related to these complications can be obtained in the literature. This study includes 42 cases of oral piercings in 39 young adults, who were using or had used oral piercings, and the complications associated with their use. Immediate complications occurred in 29 cases, including excessive bleeding (69%) and pain (52.3%) as the most representative. Two cases of syncope were found. Late complications related to the piercing insertion site were observed in 97.6% of cases, with pain and swelling being present in 92.9% and 61.9% of cases, respectively. Dental pain and lacerations on the tongue represented the most prevalent complications associated with the surrounding tissues, accounting for 33.3% and 31% of cases. The use of oral piercings is related to a series of mainly local complications, and individuals who decide to use piercings should be aware of such complications. Individuals wishing to get a part of their body pierced should do so with qualified professionals and should regularly visit the dentist so that a regular control is achieved, thus ensuring the early detection of the adverse effects associated with this practice.

    The phenomenon of body art, such as tattoos and piercings, has ancient roots, rediscovered in Western society during the '70s. The aim of this research is to investigate the prevalence and the characteristics of tattoos and piercings among Italian adolescents of high school in Padua, with particular attention to family context and temperament. Some questionnaires about the presence or the wish of tattoos/piercings, smoke and alcohol use, familiar conflicts, and some temperamental features, such as novelty seeking, harm avoidance and reward dependence, have been administered to a sample of 829 students. Tattoo and piercing's prevalence among adolescents was respectively 4% and 24%; 2.5% of the sample had both. Respectively 62% and 35% of the subjects expressed the desire of having a tattoo or piercing. A significant association has been found between tattoo/piercing's presence and smoke and alcohol use (p tattoos and piercings, are more likely to have familiar conflicts and minor perceived support and they have higher scores on the novelty seeking scale. Those who wish a tattoo/piercing showed higher reward dependence. This study confirms that tattoos/piercings are common among young people and it stresses the relevance of familiar and temperamental features, and the association between tattoos/piercings and some maladaptive behaviors, like smoke and alcohol use.

    Body piercing and tattooing are accepted by a growing number of teenagers and young adults as a way of self-expressing. Some authors suggest association between body piercings/tattoos and early sexual initiation, higher number of sexual partners, or risky sexual behaviors. The aim of the study was to evaluate sexual behaviors among young adults with body modifications (BMs)--tattoos and piercings. One hundred twenty young healthy adults, ages between 20 and 35, were included in the population study. The study group was divided into three subgroups: controls (N = 60), adults with tattoos (N = 28), and adults with piercings (N = 32). The research instrument was a self-prepared questionnaire containing 59 questions assessing socioepidemiological parameters, sexual behaviors, incidents of sexual harassment in the past, and self-attractiveness evaluation, as well as questions concerning tattoos and piercings. Socioepidemiological variables and sexual behaviors were compared between subgroups. To assess and describe the correlation between having BM--tattoos and piercing--and sexual behaviors in the population of young adults by using the logistic regression model. Adults with BMs have had their first intercourse statistically earlier and were more sexually active compared with controls. There were no statically significant differences in sexual orientation, sexual preferences, engaging in risky sexual behaviors, frequency of masturbation, and history of sexual abuse between the groups. In contrast, the frequency of sexual intercourses was statistically higher and oral sex was more likely to be a dominant sexual activity in adults with BM compared with controls. The multivariate logistic model revealed that adults with BM were four times less likely to participate in religious practices and twice more likely to have early sexual initiation. Having BM is associated with early sexual initiation and more liberal attitudes toward sexual behaviors but not with engaging in

    2011-07-01

    This paper presents a new approach, in applying the Pierce two-node model, to predict local skin temperatures of individual body parts with good accuracy. In this study, local skin temperature measurements at 24 sites on the bodies of 11 human subjects were carried out in a controlled environment under three different indoor conditions (i.e. neutral, warm and cold). The neutral condition measurements were used to adjust the local skin set-points in the model for each body part. Additional modifications to the calculation algorithm were introduced corresponding to different body parts. The local core set-points were then calculated, using a line search method, as the input values that allow the model to predict the skin temperatures with maximum deviation of ±0.1°C for the neutral condition. The model predictability was verified for the other two indoor conditions, and the results show that the modified model predicts local skin temperatures with average deviation of ±0.3°C.

  19. Pericondrite pós-piercing Post-piercing perichondritis

    Full Text Available O uso de piercing tem se tornado uma prática muito freqüente entre os jovens. O procedimento na maioria vezes realizado por profissionais não-qualificados não é isento de riscos. O manuseio de material contaminado ou a higiene imprópria predispõem à pericondrite e à celulite. A pericondrite caracteriza-se pelo eritema do pavilhão auricular, dor intensa e febre. Sem tratamento, desenvolve-se um edema generalizado do pavilhão com formação de abscesso subpericondrial, podendo evoluir para necrose isquêmica da cartilagem e a temível deformidade estética conhecida como "orelha em couve flor". O agente responsável mais encontrado é o Pseudomonas aeruginosa. No estágio inicial da doença o tratamento pode ser feito com antibióticos de amplo espectro. Nos casos em que o abscesso está presente, a incisão e drenagem cirúrgica são obrigatórios acompanhado de antibioticoterapia guiado pela cultura e antibiograma. OBJETIVO: O objetivo deste relato de caso é realizar uma revisão bibliográfica dos últimos 10 anos abordando os aspectos anatômicos do pavilhão auricular, a história do uso de piercing e suas mais conhecidas complicações. MÉTODO: Relato de um caso de pericondrite pós-piercing transcartilaginoso onde houve a necessidade de tratamento cirúrgico com praticamente nenhuma deformidade estética. RESULTADO: Aquisição de experiência teórico-prática através de revisão bibliográfica e relato de um caso de evolução favorável para a paciente. CONCLUSÃO: Incidência crescente das complicações de pericondrites na população jovem deve levar à prevenção primária mais elaborada.Piercing has become more and more popular among adolescents. The procedure is generally performed by unqualified professionals and carries its risk. Non-sterilized material or inappropiate hygiene increases the possibility of perichondritis and celulitis. The disease is characterized by erythema of the auricula pinna, unbearable pain

    To provide quantitative and qualitative data that will assist evidence-based decision making for men and women with genital piercings (GP) when they present to urologists in ambulatory clinics or office settings. Currently many persons with GP seek nonmedical advice. A comprehensive 35-year (1975-2010) longitudinal electronic literature search (MEDLINE, EMBASE, CINAHL, OVID) was conducted for all relevant articles discussing GP. Authors of general body art literature tended to project many GP complications with potential statements of concern, drawing in overall piercings problems; then the information was further replicated. Few studies regarding GP clinical implications were located and more GP assumptions were noted. Only 17 cases, over 17 years, describe specific complications in the peer-reviewed literature, mainly from international sources (75%), and mostly with "Prince Albert" piercings (65%). Three cross-sectional studies provided further self-reported data. Persons with GP still remain a hidden variable so no baseline figures assess the overall GP picture, but this review did gather more evidence about GP wearers and should stimulate further research, rather than collectively projecting general body piercing information onto those with GP. With an increase in GP, urologists need to know the specific differences, medical implications, significant short- and long-term health risks, and patients concerns to treat and counsel patients in a culturally sensitive manner. Targeted educational strategies should be developed. Considering the amount of body modification, including GP, better legislation for public safety is overdue. Copyright © 2011 Elsevier Inc.

    The present study examined the prevalence and acceptance of body piercings and tattoos among a community sample from the southern German-speaking area of Central Europe. A total of 440 respondents completed information about their own body piercings and tattoos and reported whether they would be likely never to have piercings and tattoos in the future. Analyses indicated that 19.8 and 15.2% of respondents had piercings (excluding the earlobe) and tattoos, respectively. Women were more likely to have body piercings than men, but there were no sex differences in tattooing. There were also few sociodemographic differences in piercings and tattoos, and most participants reported being likely to consider body art in the future. These results are considered in relation to prevalence estimates of body art in other Western countries and the associated health risks.

    Body piercing has become increasingly prevalent. We describe a case of breast infection with combined mycobacteria and anaerobe following nipple piercing, and review the literature. A 17-year-old female developed a breast abscess 4 months after nipple piercing. Cultures grew Prevotalla melangenica and Mycobacterium fortuitum. She required drainage and antibiotic treatment. Three months into her treatment she stopped her medications, relapsed, and required drainage. Two months later, on antimycobacteria therapy, her wound is healing. Review of the infectious complications of nipple piercing yielded 12 cases, 5 of which had a foreign body. The pathogens isolated (coagulase negative staphylococcus, mycobacteria, streptococcus, anaerobe, and gordonia) are not the usual organisms to be isolated from a breast abscess. This could result from reporting bias or the presence of a foreign body, the nipple ring. The three cases of mycobacteria, in addition to ours, are reviewed. The average age is 22 years. Three to 9 months elapsed between piercing and infection. All cases required drainage. Antimycobacteria therapy was used in three of the four cases for 10 days to 6 months. With the increasing prevalence of body piercing, it is important to document and report infections. We describe a breast abscess following nipple piercing with combined anaerobic and a mycobacterial pathogens. This underscores the need for obtaining cultures including anaerobes and mycobacteria.

    Tattooing and piercing have become increasingly popular in recent years. Both methods involve several medical risks, including transmission of infectious diseases. There are many reports on wound infections as well as transmission of hepatitis and human immunodeficiency viruses etc. According to these facts special hygiene regulations for tattooing and piercing have been published in Germany. Based on these regulations the public health department of the city of Frankfurt am Main, Germany, carried out special hygiene controls in such studios, one a year. Special tattoo or piercing exhibitions were also controlled. Results are reported here. Studios for tattoos or piercing were informed about hygiene rules and annually controlled from 1995-1999, using a special check list on cleanliness in the studios, disinfection and sterilisation procedures etc. For permission of tattoo and piercing exhibitions special hygiene orders were made mandatory. During 1995-1997 the absolute number of complaints decreased from 20 to 9, in spite of the increasing number of tattoo studios in Frankfurt am Main (from 6 to 10). This was true also of the tattoo and piercing exhibitions. After 1 year without control visits however, an increase of complaints was to be seen in 1999. According to our experience tattooists and piercers are interested in good hygiene practice. But our data showing the worsening hygiene data in one year without control visits also demonstrate the necessity of regular controls by the authorities. According to the reports on infectious complications of tattooing and piercing and according to the data reported here hygienic advice and control is an important task of Public Health services.

    The aim of the study was to determine the level of life satisfaction and the various dimensions of self-esteem of pierced or tattooed people, and evaluate their mental health, compared to those without similar body modifications. The study was conducted on a sample of 449 people aged 16-58 years (mean age 26.7 ± 6.35), of whom 308 had body modifications: tattoo (n = 90), body piercings in places other than the ear lobe (n = 53), or both tattoos and piercings (n = 165). The control group consisted of 141 people without such modifications. The participants completed a questionnaire concerning their socio-demographic status, as well as the following psychological tests: The Satisfaction with Life Scale (SWLS), Multidimensional Self-Esteem Inventory (MSEI) and General Health Questionnaire (GHQ-28). Our findings show no significant differences in terms of life satisfaction between the group with tattoos or piercings and the control group. People with body modifications were characterized by higher self-esteem, with regard to their competence and leadership abilities. They also display fewer symptoms of social impairment and sleep disorders than the control group. Tattoos and piercings should not be considered as indicators of psychopathology.

    The objective of this study was to assess attitudes of patrons and medical school faculty about physicians with nontraditional facial piercings. We also examined whether a piercing affected the perceived competency and trustworthiness of physicians. Survey. Teaching hospital in the southeastern United States. Emergency department patrons and medical school faculty physicians. First, patrons were shown photographs of models with a nontraditional piercing and asked about the appropriateness for a physician or medical student. In the second phase, patrons blinded to the purpose of the study were shown identical photographs of physician models with or without piercings and asked about competency and trustworthiness. The third phase was an assessment of attitudes of faculty regarding piercings. Nose and lip piercings were felt to be appropriate for a physician by 24% and 22% of patrons, respectively. Perceived competency and trustworthiness of models with these types of piercings were also negatively affected. An earring in a male was felt to be appropriate by 35% of patrons, but an earring on male models did not negatively affect perceived competency or trustworthiness. Nose and eyebrow piercings were felt to be appropriate by only 7% and 5% of faculty physicians and working with a physician or student with a nose or eyebrow piercing would bother 58% and 59% of faculty, respectively. An ear piercing in a male was felt to be appropriate by 20% of faculty, and 25% stated it would bother them to work with a male physician or student with an ear piercing. Many patrons and physicians feel that some types of nontraditional piercings are inappropriate attire for physicians, and some piercings negatively affect perceived competency and trustworthiness. Health care providers should understand that attire may affect a patient's opinion about their abilities and possibly erode confidence in them as a clinician.

    Nipple piercing gains popularity and social acceptance within the last years, especially among young people. The medical literature reports an increase of complications in the post-piercing period. We report a case of a young woman, who presented with a light enlargement of the right breast and tenderness in the retroareolar region following nipple piercing 5 months ago. On ultrasound, a poorly marginated hypoechoic lesion was seen which was suspicious of an inflammation. After 1 week of antibiotic therapy, the mass had enlarged. As carcinoma could not be excluded, open biopsy was performed. Histology showed signs of chronic mastitis. To date, only a few reports of breast abscess after nipple piercing have been published. With the increasing prevalence of body piercing, it is important to document and report infections which may be discovered many months following piercing. Carcinoma can mimic breast abscess and should be included in the differential diagnosis.

  9. Body piercing and tattoo: awareness of health related risks among 4,277 Italian secondary school adolescents

    2010-01-01

    Background The awareness of health risks associated with body art among secondary school pupils has never previously been studied in depth. A large sample of secondary school adolescents from the Veneto Region (North East Italy) were investigated in order to inform health education programs. Methods 6 public secondary schools from each of the 7 Provinces of the Veneto Region were selected. All students attending the 1st, 3rd, and 5th school years were surveyed by an anonymous self administered questionnaire on their perception of health risks related to body art and other explanatory variables. Logistic regression analysis was employed, reporting adjusted Odds Ratios (OR) with 95% Confidence Interval (CI). Results Among 4,277 available students (aged 14-22 years), boys were consistently: less knowledgeable of infectious diseases related to body art (OR = 0.78; CI: 0.66, 0.94), less likely to be aware of the hygienic norms to be observed in a body art parlour (OR = 0.54; 0.44, 0.65), less likely to refer to a certified body art parlour (OR = 0.56; 0.48, 0.66), less likely to refer to a professional health care provider for complications related to body art (OR = 0.71; 0.59, 0.86). Students attending the first school year (baseline) had a lesser knowledge of body art related infectious diseases, were less likely to refer to a certified body art parlour, and to know the mandatory hygienic rules to be observed when performing body modifications. Interviewees from the provinces of Rovigo and Vicenza were less likely to be conscious of the health risks associated with body modifications, and those with tattoos were less knowledgeable about the infection risk (OR = 0.60; 0.42, 0.86) and less likely to refer to a professional health care provider in case of medical complication (OR = 0.68;0.48, 0.95). Students with piercings were less likely to refer to a certified practitioner for receiving body art (OR = 0.62; 0.50, 0.77) or therapy for medical complications (OR = 0

    2001-12-01

    The motives, family experiences, and personality characteristics of 341 college students with and without tattoos or piercings were studied. Participants completed Lippa's 1991 measures of the Big Five personality factors, a shortened version of the Body Cathexis Scale, a series of questions about their childhood experiences, and questions about risk-taking behaviors. In addition, reasons to have or not have body modifications and the perceptions of people with body modifications were investigated. Of the 116 men and 186 women, 25% and 33%, respectively, had at least one tattoo or body piercing. There were very few differences in the childhood experiences or personality characteristics of people with or without body modifications. Although people with body modifications did not differ from people without modifications on the Big Five personality measures, people without modifications perceived people with modifications as much different from themselves on these measures. These results indicate that tattoos and piercings in college students are associated with significantly more risk-taking behavior, greater use of alcohol and marijuana, and less social conformity. However, the traditional stereotype that body modifications are indicators of social or personal pathology does not describe contemporary college students.

    Abstract The objective of the study was to evaluate the link between tattoos and/or piercings and young people's tobacco consumption. A total of 2587 students (1168 females and 1419 males) were asked about tattoos, piercings, and tobacco consumption. Young men and young girls who had tattoos and/or wore piercings were more likely to report smoking behavior, earlier smoking behavior, and higher cigarette consumption per day. It was also found that both with men and women, the combined effects of piercings and tattoos were associated with an increase in smoking behavior. Piercings and/or tattoos as well as combined piercings and tattoos appeared as markers of tobacco consumption. Such marks could serve as signs for educators, parents, and physicians.

    Background The aim of the study was to focus the awareness of complications of oral piercing among a group of adolescents and young Italian adults with intraoral piercings. Material and Methods A total of 225 teenagers were asked to complete a questionnaire on the awareness of complications of oral piercing. An additional questionnaire was administered in case of oral piercing worn, based on site piercing, knowledge about piercer license, oral and systemic risks due to oral piercing, disinfection and sterilization of the material pierced, information by the piercer about piercing hygiene maintenance and post-piercing dentist check-up. After questionnaire all partecipants received a brochure with some information about risks and maintenance mode of piercing. Results Data revealed that more than 50% of teens surveyed was found to wear a piercing. Only 25.3% was aware of the risk of HCV cross-infection and only 17.3% reported of knowledge about risk of endocarditis. Only 17% checked the piercer license and only 18% sterilization and disinfection of the materials used. 53.7% did not received explanations about the risks associated with piercing. With regard to the maintenance mode of the piercing, it has been suggested to brush the piercing bar in 17% of cases. The post piercing specialist visits have been suggested only in 7% of cases. Conclusions The general lack of awareness of complications and maintenance mode related to oral piercing needs to be addressed by some education programs performed at school and by dentists.

    Reliable psychosocial data about practitioners of body piercing and tattooing are few and controversial. The goal of this study was to reinvestigate the issue by studying a large sample of individuals with body modifications (BMs), focusing on the motives and relations to biographical events. A 55-item anonymous self-report questionnaire was distributed among volunteers of what is considered to be a core group of individuals wearing BMs (N=432). Results show that BMs changed the participants' attitude toward their body considerably, and 34% of all participants reported BM practices in conjunction with decisive biographical events. Twenty-seven percent of the participants admitted self-cutting during childhood. This group differed from the group without self-cutting with respect to several features before, during, and after BM. The rate of medical complications of BM was 16% in the total sample, with a remarkably higher rate (26%) among participants with a history of self-cutting. The data suggest that the significance of BMs ranges from simple peer group imitations to highly informative symptoms of possibly severe psychopathological conditions. In the latter case, BMs sometimes serve as therapeutic substitutes.

    To explore possible effects of tongue piercing on perceived speech quality. Using a quasi-experimental design, we analyzed the effect of tongue piercing on speech in a perception experiment. Samples of spontaneous speech and read speech were recorded from 20 long-term pierced and 20 non-pierced individuals (10 males, 10 females each). The individuals having a tongue piercing were recorded with attached and removed piercing. The audio samples were blindly rated by 26 female and 20 male laypersons and by 5 female speech-language pathologists with regard to perceived speech quality along 5 dimensions: speech clarity, speech rate, prosody, rhythm and fluency. We found no statistically significant differences for any of the speech quality dimensions between the pierced and non-pierced individuals, neither for the read nor for the spontaneous speech. In addition, neither length nor position of piercing had a significant effect on speech quality. The removal of tongue piercings had no effects on speech performance either. Rating differences between laypersons and speech-language pathologists were not dependent on the presence of a tongue piercing. People are able to perfectly adapt their articulation to long-term tongue piercings such that their speech quality is not perceptually affected.

    Oral and perioral piercings have recently become very popular and many patients present at dental clinics and practices with jewellery inserted into the oral and perioral tissues. It is imperative that oral health care professionals become familiar with this practice, become aware of its sequelae, and are able to provide oral health education regarding oral hygiene and care of the piercing. The present study investigated the sites of oral piercings, complications associated with piercings, plaque control procedures practised by piercees, and the attitude and behaviour of piercers towards infection control and prevention of complications after a piercing. A convenience sample was used and 126 piercees and 10 piercers completed a self-administered questionnaire. Of the 126 participants (107 females and 19 males), 88.10% had a tongue piercing, 19.84% had a lip piercing and 7.94% had both. The most common immediate post-procedure sequelae were pain (69.05%), swelling (52.38%) and difficulty eating, speaking and swallowing (70.63%). Long-term complications were reported by 17.56% of the sample, and included chipping of teeth, gingival recession, lesions on the tongue and palate, painful gums, and sensitivity of teeth. Oral health professionals need to be aware of the risk of damage to soft and hard tissue, and their role in informing patients about the potential risks, if consulted before a piercing.

The authors take into consideration Italian regulation on tattooing and piercing, in particular in relation to adolescents. In Italy, several regions have therefore issued acts aimed at regulating the activities of tattoo and piercing also in reference to minors. Discussion. With regard to minors, the rules taken into account set precise limits in relation to the age criterion and subordinate the implementation of such practices to the provision of consent by legal representatives. If such practices are of an aesthetic nature, we cannot avoid considering the implications they have on health protection, and then adopt appropriate measures to protect the person who intends to undergo them, particularly in the case of minors.

    General and subjective information about those who chose to obtain genital piercings was presented. Particularly, the assumptions made from the literature are refuted by objective and subjective data collected from intimately pierced individuals themselves. Professional nurses must not base practice decisions on assumptions but on the "best evidence with clinical experience, research, (as well as) associated patient values" (Sackett, Strauss, Richardson, Rosenberg, & Haynes, 2001, p. 10). Thus, providing clinically competent care is driven by the latest knowledge and evidence from research and patient sources. Data found here provide further empirical evidence that may help to improve client outcomes by advancing evidence-based nursing practice in relation to people with genital piercings.

    A modified self-piercing rivet (SPR) has been proposed to mechanically fasten CFRP laminates. The modified SPR consists of a rivet body and two flat washers. The two flat washers were used to suppress delamination in the CFRP laminates at the point of piercing. The advantages of the modified SPR for fastening CFRP laminates are instantaneous process time and low cost. Any pretreatments such as surface treatments or hole drilling are not required. In this study, the viability of the modified S...

    A well-known Pierce's solution that allows to focus a beam of charged particles using properly shaped electrodes outside the beam is generalized to the case of multigap accelerating system. Simple parametric formulae for Pierce electrodes are derived for an accelerating system with current density, limited either by space charge or by emitting property of the cathode. As an example of general approach, Pierce electrodes shape is analyzed for a system with two accelerating gaps. It is shown that precise Pierce's solution exists if acceleration rate within second gap is lower than within first gap. In the opposite case quasi-Pierce solution can be implemented using non-equipotential electrode between the gaps, and guidelines, based on numerical simulations, for the design of equipotential focusing electrodes are given

    Piercing has become more and more popular among adolescents. The procedure is generally performed by unqualified professionals and carries its risk. Non-sterilized material or inappropiate hygiene increases the possibility of perichondritis and celulitis. The disease is characterized by erythema of the auricula pinna, unbearable pain and fever. Left untreated, the condition progresses with edema along the auricula and abscess formation that may result in ischemic necrosis and a cauliflower anesthetic deformation. The most common bacteria is Pseudomonas aeruginosa. In cases with abscesses, drainage is necessary along with antibiotic therapy guided by cultures and antibiogram. The aim of this case report was to review the past 10 years of published papers dealing with anatomical aspects of the auricular pinna, the history of piercing and its most common complications. A case report of perichondritis after 'high' ear piercing that required surgical treatment and that progressed with no esthetic loss. Theoretical and practical experience based on a review and a report of a case that progressed satisfactorily. The increased incidence of perichondritis in adolescents should require more elaborated primary prevention measures.

    Full Text Available In the present study, a towed underwater particle image velocimetry (PIV system was validated in uniform flow and used to investigate the free-surface effects on the turbulent wake of a simple surface-piercing body. The selected test model was a cylindrical geometry formed by extruding the Wigley hull's waterplane shape in the vertical direction. Due to the constraints of the two-dimensional (2D PIV system used for the present study, the velocity field measurements were done separately for the vertical and horizontal planes. Using the measured data at several different locations, it was possible to identify the free-surface effects on the turbulent wake in terms of the mean velocity components and turbulence quantities. In order to provide an accuracy level of the data, uncertainty assessment was done following the International Towing Tank Conference standard procedure.

    Full Text Available The prevalence of genital piercing among women is increasing. As the popularity increases, the number of complications from infection, injury, and retained jewelry is likely to rise. Techniques to remove embedded jewelry are not well described in the literature. The purpose of this report was to describe a case of a patient with a retained clitoral glans piercing, discuss a simple technique for outpatient removal, and review current evidence regarding associated risks of clitoral piercings. A 24-year-old female presented to the emergency department with an embedded clitoral glans piercing. Local anesthetic was injected into the periclitoral skin and a small superficial vertical incision was made to remove the ball of the retained barbell safely. In conclusion, among patients with retained genital piercing, outpatient removal of embedded jewelry is feasible. While the practice of female genital piercing is not regulated, piercing of the glans of the clitoris is associated with increased injury to the nerves and blood supply of the clitoris structures leading to future fibrosis and diminished function compared to piercing of the clitoral hood.

    2011-07-01

    Euler diagrams are effective tools for visualizing set intersections. They have a large number of application areas ranging from statistical data analysis to software engineering. However, the automated generation of Euler diagrams has never been easy: given an abstract description of a required Euler diagram, it is computationally expensive to generate the diagram. Moreover, the generated diagrams represent sets by polygons, sometimes with quite irregular shapes that make the diagrams less comprehensible. In this paper, we address these two issues by developing the theory of piercings, where we define single piercing curves and double piercing curves. We prove that if a diagram can be built inductively by successively adding piercing curves under certain constraints, then it can be drawn with circles, which are more esthetically pleasing than arbitrary polygons. The theory of piercings is developed at the abstract level. In addition, we present a Java implementation that, given an inductively pierced abstract description, generates an Euler diagram consisting only of circles within polynomial time.

    2017-12-13

    Background: In recent years, increasing numbers of adults and adolescents have opted to undergo tattoo and piercing procedures. Studies among adolescents with tattoo and piercing have usually explored the relationship between one factor and the decision to have tattoos and/or piercings. The aim of this study was to determine relationships between body cosmetic procedures and selfesteem, propensity for sensation seeking, and risk behaviours among adults. Materials and Methods: The subjects were divided into two groups, i.e. , those with (n=429) and those without tattoos/piercings (n=237), and self-esteem, propensity for sensation seeking, and risk behaviour were compared between the two groups using self-report questionnaires. To analyse differences in self-esteem and the propensity for sensation seeking, general characteristics were statistically adjusted. In addition, general characteristics, self-esteem, and propensity for sensation seeking were statistically adjusted to determine differences in the propensity for risk behaviour between the two groups. Results: Significant differences were observed in age, marital status, income level, occupation, values or sensitivity to fashion, and educational level between the group with and that without tattoos/ piercings. There was no significant difference in self-esteem, whereas there were significant differences in the propensity for sensation seeking and risk behaviour between the two groups. Conclusions: Continuous attention to, and interest in, the increased incidence of tattooing and piercing are necessary, especially in terms of public interventions for health education and health promotion, as these forms of self-adornment are associated with behaviours that pose a risk to health.

In this study, we determine the trends and complications of ear piercing among selected Nigerian population. Aim and Objectives: The aim and objective of this study was to draw attention to the trends and complications of ear piercing with a view to prevent its associated complications. Methodology: It is a descriptive cross-sectional study carried out between February and May 2015 among selected Nigerian population from two of its six geo-political zones. A self-administered semi-structured questionnaire which had been pretested was used to collect data from 458 respondents who consented using multistage sampling technique. Results: Of 480 respondents enumerated, 458 completed the questionnaires and gave their biodata. The male:female ratio was 1:6.2. Their ages ranged from 18 to 75 years with a mean of 35.56 ± 10.16. About 35.4% of the respondents were within the age group of 31–40 years. Majority of the respondents, i.e.,79.3% practiced ear piercing on their children. Most of them (86.8% preferred single piercing. Ear piercing was performed within the 1st week of birth in 37.2% of the respondents. Large percentage (93.2% of the respondents will not encourage ear piercing in male children. Nearly 20.5% of the respondents observed complications. Conclusion: Ear piercing remained a common practice in Nigeria, with respondents preferring it on females. Majority of the piercings are done in childhood and by untrained personnel. Keloid formation was the notable complication observed by the respondents. There is a need to increase awareness about the hazards of ear piercings and to enact laws that regulate ear piercings particularly in children which is hereby stretched.

    2014-03-01

    Full Text Available Tattoos and piercings can become a mask to hide behind? Everything can become a mask if we use it for masquerading. The tattoo is the anthropological roots of ancient and modern makeup that refers to the mask understood as that which creates the face, which gives it its social being. The tattoo is also an artistic decoration that should be born by the deep desire to communicate yourself to others. Tattoos must be able to "tell" the people who wear them, but if the latter decorate their body with a message or image that does not belong, it can cause the destruction of individuality. The tattoo is immortal. It can be a permanent dress, a way to resist the unwanted transformations using a piece of subjective identity, non-imitable, from which one cannot be excluded. Along with careful identification of psycho-sociological motivations that drive a young man to want a tattoo, you need to traverse an education that not only form a personality, teaches the knowledge of his own body. Getting a tattoo means not only change the morphology of the body but the risk of jeopardizing their health. Responsibility for their own health also means being aware that a tattoo can procure mild side effects or more severe depending on the initial state of health of the subject. Then a tattoo only after a careful history following the favorable opinion of the doctor and after a personal assessment aware. These initial objectives of a path bioethical-pedagogical significant.

    A 33-year-old man was referred to our institution with papillary masses at the urethral meatus and difficulty urinating. Genital examination showed two piercings on the frenulum, which were penetrating the external urethra. Endoscopic examination revealed papillary tumours over the entire circumference of the penile urethra and the piercing site. The tumours were resected transurethrally. Microscopic examination revealed condylomata acuminata. Human papillomavirus types 6 and 66 were detected in the lesions. Retrograde urethral viral infection is rare because of the protection provided by the mucosal immune system. Genital piercing may have facilitated spread of the human papillomavirus into the urethra.

  9. Pierce instability and bifurcating equilibria

    International Nuclear Information System (INIS)

    Godfrey, B.B.

    1981-01-01

    The report investigates the connection between equilibrium bifurcations and occurrence of the Pierce instability. Electrons flowing from one ground plane to a second through an ion background possess a countable infinity of static equilibria, of which only one is uniform and force-free. Degeneracy of the uniform and simplest non-uniform equilibria at a certain ground plan separation marks the onset of the Pierce instability, based on a newly derived dispersion relation appropriate to all the equilibria. For large ground plane separations the uniform equilibrium is unstable and the non-uniform equilibrium is stable, the reverse of their stability properties at small separations. Onset of the Pierce instability at the first bifurcation of equilibria persists in more complicated geometries, providing a general criterion for marginal stability. It seems probable that bifurcation analysis can be a useful tool in the overall study of stable beam generation in diodes and transport in finite cavities

    Full Text Available The present study analyses factors associated with the propensity for piercing and tattooing among adolescents, from a survey conducted in 2007 in high schools in the Veneto Region (Northeast Italy. After some descriptive analyses, multinomial logistic regression models were applied to identify what predicts the practice of, interest in, or indifference to piercing and tattooing. Results show gender differences in the approach to body modification: For girls, body art is considered a mainstream activity involving younger cohorts; piercing and tattooing become a way of increasing their own body satisfaction. For boys, factors connected with the propensity for these practices are a low cultural background and the importance given to physical appearance. For both boys and girls, a significant aspect in defining attitudes toward body art practices is the values system: Values such as enjoyment, beauty, and youth, are found to be closely connected with a high propensity for these practices.

    The use of tattoos and piercings has increased, especially among adolescents in the last decades. To evaluate the prevalence of these behaviors in adolescents and their association with risk behaviors such as alcohol, tobacco and illicit drug use and sexual promiscuity. An anonymous and confidential survey about tattooing and piercings was applied to randomly selected high school teenagers, attending municipal, private-subsidized and private schools, in four sectors of Santiago (north-east, south-east, north-west, south-west). The surveys were answered by 1329 participants with a mean age of 15 years (62% women) from 9 schools in Santiago. The prevalence of tattoos was 1.7% (confidence intervals (CI) 1.1% to 2.5%). The figure for piercings was 30.6% (CI 28.2 to 33.1%). A higher prevalence of tattooing and piercings was observed in groups with a history of psychiatric disorders, criminal records, alcohol, tobacco and illicit drug consumption and initiation of sexual activity (p < 0,001). This study confirms that tattoos and piercings are indicators of adolescent risk behaviors.

    The aim of the present investigation was to examine the possibility of reducing lubrication and replacing expensive tungsten carbide material in blanking/piercing through introduction of hard tool coatings. Results show that hard PVD coatings can be successfully used in blanking/piercing...... critical value under dry friction conditions and leads to tool failure. Therefore, at present oxidation and temperature resistant hard coatings can give improved wear resistance of stamping tools, but elimination of lubricants in blanking and piercing processes is still not feasible....

  1. Behaviour and Modelling of Self-piercing Screw and Self-piercing Rivet Connections: An Experimental and Numerical Investigation

    Full Text Available Objective: To identify the profile of oral piercing users and the possible implications resulting from its use, as well as explaining to dentists about the possible consequences to their patients as a result of wearing this type of jewelry in the oral region.Methods: Fifty-one oral piercing users were interviewed. They were aged between 18 and 42 year, from different social classes, and resident in the city of Santa Maria, Rio Grande do Sul, Brazil.Results: Based on the questionnaires analyzed, the majority of users had tongue or lip piercing as a way to express identity, and 45% reported the occurrence of some type of oral and/or general alteration associated with the use of piercings. Conclusion: The majority of alterations are harmful to the piercing user’s health, therefore, professionals in the Dentistry area must be warnedto explain to their patients, who use oral piercings, about the consequences that may occur and the need for special care to ameliorate these problems.

    To systemically search the literature for case reports concerning adverse effects associated with oral and peri-oral piercings on oral health and/or general health.   MEDLINE and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched up through 1 April 2010 to identify appropriate studies. Independent screening of the titles and abstracts identified 1169 papers from MEDLINE and 73 papers from CENTRAL. Subsequently, 67 papers describing 83 cases were processed for data extraction. The case reports described complications in oral and general health. In this review, 96 complications were described for 83 cases. Of the 96 reported complications, 81% (n=84) occurred in cases of tongue piercings, 20% (n=21) in cases of lip piercings and 1% (n=1) in cases of other oral piercings. In eight cases, subjects had two oral and/or peri-oral piercings. Gingival recession was the most frequently described complication. Periodontitis and gingival recession were seen at the central mandibular incisors. Tooth fracture is mostly reported in subjects with tongue piercings. Among the case reports, there were complications like normal post-operative swelling and localized inflammation but also more serious complication that may even have been life threatening. Also in the long term, piercing may be associated with gingival recession and tooth fracture. Therefore, oral and/or peri-oral piercings are not without risks. Patients considering a piercing should be made aware of this. Those patients wearing a piercing should be screened by a dental professional for possible complications on a regular basis. © 2011 John Wiley & Sons A/S.

    2011-09-01

    The purpose of this series was to review the spectrum of clinical and sonographic features associated with infection after nipple piercing. Between 2002 and 2010, 6 patients presented to our breast center with a breast abscess after nipple piercing. A retrospective analysis of the imaging findings was performed with clinical and pathologic correlation. Patients with breast infections after nipple piercing tend to be young, and the timing since piercing varies from 2 weeks to 17 months. Sonography showed a complex or hypoechoic mass in 5 of 6 patients. Treatment of breast abscesses included surgical incision and drainage, percutaneous drainage, and antibiotic therapy. Surgical evacuation is commonly performed; however, sonographically guided aspiration may be an appropriate management strategy.

    This review determines the incidence of complications associated with lip and/or tongue piercings based on a systematic evaluation of the available literature. MEDLINE-PubMed, Cochrane-CENTRAL and EMBASE databases were comprehensively searched through June 2014 to identify appropriate studies. The incidence of complications, as established by a dental professional associated with oral and peri-oral piercings, was evaluated in populations with lip and/or tongue piercings. The quality of the case-control studies was assessed using the Newcastle-Ottawa Scale. For case series studies, the risk of bias was assessed using the National Institute for Health and Clinical Excellence scale. An independent screening of 1580 unique titles and abstracts revealed 15 publications that met the eligibility criteria. The incidence of gingival recessions appeared to be 50% in subjects with lip piercings and 44% in subjects with a tongue piercing. Tooth injuries were observed in 26% individuals with lip piercings and in up to 37% of individuals with tongue piercings. Subjects with a lip piercing were 4.14 times (P = 0.005) more likely to develop gingival recession than those without a lip piercing. Subjects with a tongue piercing were more likely than non-pierced subjects to experience gingival recession (relative risk (RR) 2.77; P = 0.00001) and tooth injuries (RR 2.44; P = 0.003). Both lip and tongue piercings are highly associated with the risk of gingival recession, and tongue piercings are also associated with tooth injuries. © 2015 John Wiley & Sons A/S.

    Full Text Available The purpose of this work was to verify in vitro adherence of E. corrodens and S. oralis to the surface of tongue piercings made of surgical steel, titanium, Bioplast, and Teflon. For this, 160 piercings were used for the count of Colony Forming Units (CFU and 32 piercings for analysis under scanning electron microscopy. Of these, 96 (24 of each type were individually incubated in 5 mL of BHI broth and 50 μL of inoculum at 37°C/24 h. The other 96 piercings formed the control group and were individually incubated in 5 mL of BHI broth at 37°C/24 h. Plates were incubated at 37°C/48 h for counting of CFU/mL and data were submitted to statistical analysis (p value <0.05. For E. corrodens, difference among types of material was observed (p<0.001 and titanium and surgical steel showed lower bacterial adherence. The adherence of S. oralis differed among piercings, showing lower colonization (p<0.007 in titanium and surgical steel piercings. The four types of piercings were susceptible to colonization by E. corrodens and S. oralis, and bacterial adhesion was more significant in those made of Bioplast and Teflon. The piercings presented bacterial colonies on their surface, being higher in plastic piercings probably due to their uneven and rough surface.

    Background. Dermal piercings have recently become a fashion symbol. Common complications include hypertrophic scarring, rejection, local infection, contact allergy, and traumatic tearing. We report a rare case of Mycobacterium fortuitum following a dermal piercing and discuss its medical implications and treatments. Case. A previously healthy 19-year-old woman presented complaining of erythema and edema at the site of a dermal piercing on the right fourth dorsal finger. She was treated with a 10-day course of trimethoprim-sulfamethoxazole and one course of cephalexin by her primary care physician with incomplete resolution. The patient stated that she had been swimming at a local water park daily. A punch biopsy around the dermal stud was performed, and cultures with sensitivities revealed Mycobacterium fortuitum. The patient was treated with clarithromycin and ciprofloxacin for two months receiving full resolution. Discussion. Mycobacterium fortuitum is an infrequent human pathogen. This organism is a Runyon group IV, rapidly growing nontuberculous mycobacteria, often found in water,soil, and dust. Treatment options vary due to the size of the lesion. Small lesions are typically excised, while larger lesions require treatment for 2–6 months with antibiotics. We recommend a high level of suspicion for atypical mycobacterial infections in a piercing resistant to other therapies. PMID:24073343

    Humans are characterized by a compulsive tendency to distinguish themselves from the rest: differences in clothes, hairstyle or "decorative" details are used to this effect, based on highly diverse criteria. Such differentiating practices may be aimed at identification with a certain ideological group, for example, or with a concrete "fashion", and involve the use of jewelry, clothes, unusual attire, hairstyles, mutilations, etc. In this context, the present review addresses certain aspects of mutilation practices from both the general and specifically dental perspectives. Mutations imply permanent or lasting sectioning or lesions of a part of the body, and comprise skeletal deforming, dental mutilations, circumcision, ablation of the clitoris, scarification, tattoos, and perforations (particularly of the soft tissues). In this sense, tattoos and perforations or piercings are popular -- particularly among adolescents. This trend may be interpreted as a form of communication, identity expression, or as a type of body cult (i.e., so-called "body art"). Such mutilating practices reflect different motivations including fashion, rebelliousness, differentiation, sexual motives, the remembering of events, physical sensations, and ethnic or tribal influences. However, these practices can cause complications such as infections, laceration and soft and hard tissue damage, hypersensitivity reactions and other alterations of variable severity. Under these premises, questions are raised concerning the competence of those who perform these mutilations, the preventive measures adopted, and the legal conditions under which tattoos and piercings are made in our society.

  14. A Simulation for the Punchless Piercing Process using Lemaitre Damage Model

    Lee, Sang Wook; Pourboghrat, Farhang

    2005-01-01

    The punchless piercing is a process that uses highly pressurized fluid instead of the conventional punch to make holes into the sheet metal. This process has many advantages over the conventional method for piercing various shaped holes into very thin strips of metal, composite, etc. An important cost advantage comes from not having to use a punch. Another important advantage comes from the top quality of pierced holes produced by punchless piercing, as no secondary finishing process will be needed for removing burrs typically found in conventional cutting processes. The ABAQUS/Explicit FEM code coupled with Lemaitre damage model has been used to more precisely characterize the punchless piercing process. The formulation adopted for this purpose focuses on the development of an efficient stress integration algorithm and development of a user material subroutine (VUMAT). For verification, the computed results have been compared with those of the experimental results in the literature and shown to be in good agreement with each other. The results obtained from this work are expected to be of significant interest to automotive and aerospace industries interested in using the punchless piercing process

    To assess periodontal health of individuals with a lateral lower lip piercing and describe associated periodontal, dental and mucosal complications. A split-mouth study was performed in a sample of 50 patients with a lateral lower lip piercing who attended the Periodontal Pathology and Surgery Unit of the Dental School of the University of Barcelona. The patients underwent periodontal, dental and mucosal examination on both the piercing and the control sides. Piercing users were predominantly women (78%), with a mean age of 21.3 years (SD=4.4). The amounts of keratinized and attached gingiva were significantly lower on the piercing side, and the prevalence of gingival recession was higher (p=0.012). The canine and first bicuspid teeth were the most affected. Tooth fractures and cracks were more frequent on the piercing side (20%) when compared with the control (4%). Mucosal alterations were found in seven patients. The use of lateral lower lip piercings enhances gingival recession and reduces the amounts of keratinized and attached gingiva. These ornaments are also associated with tooth fractures and cracks.

  18. Infections associated with body modification

    Full Text Available Although exact statistics are lacking, body modifications for cosmetic purposes are performed in many countries. The commonest forms include tattooing, body piercing, and breast and facial augmentation using implants or injectable fillers. Liposuction and, to a lesser extent, mesotherapy are also practiced in many countries. Infective complications of these procedures include local infections, transmission of bloodborne pathogens (viral hepatitis and human immunodeficiency virus, and distant infections such as infective endocarditis. Presence of foreign bodies, long healing time of piercing wounds, and poor compliance with infection control practices of some practitioners all predispose the recipients to infections. Apart from the endogenous microbial flora of the skin and mucosae, atypical mycobacteria, especially the rapid growers, have emerged as some of the most important pathogens in such settings. Outbreaks of infection are commonly reported. We hereby review the current knowledge of the topic with specific focus on infections associated with tattooing, body piercing, breast augmentation, mesotherapy, liposuction, and tissue filler injections. Greater awareness among consumers and health-care professionals, as well as more stringent regulations by the health authorities, is essential to minimize the health risks arising from these procedures.

    Irena Wikiera-Magott

    2017-12-01

    Full Text Available Acute kidney injury is an abrupt decline of renal function interfering with the body’s homeostasis. It most commonly occurs in neonates and children treated in intensive care units and undergoing extensive surgical procedures, especially cardiac surgery. Its aetiology is frequently complex, with infectious factors, toxic chemical activity and hydration and electrolyte imbalance occurring simultaneously and aggravating kidney injury. This study reports a case of a 17-year-old female patient in whom acute kidney injury was caused by a combination of factors, including sepsis, adverse effects of analgesic drugs and dehydration. Staphylococcus aureus infection caused by multiple-site piercings performed in a home setting resulted in the development of multiple skin abscesses, myometrial abscesses and a generalised infection. The patient’s condition warranted intensive antibiotic therapy and drainage of the myometrial abscesses. The therapy facilitated eradication of the infection foci and normalising renal function.

It is shown that the instability has always the Raman character and is threshold less in current for the Pierce boundary conditions. It permits sufficiently strictly to define the instability saturation level from breaking the resonance condition and to estimate the radiation efficiency

    Tohme, Rania A.; Holmberg, Scott D.

    2015-01-01

    Tattoos and piercings are increasing, especially among youths, but the risk of hepatitis C virus (HCV) infection from these practices has not been adequately assessed and there are conflicting findings in the literature. We evaluated the risk of HCV infection from tattooing and piercing using the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines. Studies that specified the venue of tattooing and/or piercing showed no definitive evidence for an increased risk of HCV infection when tattoos and piercings were received in professional parlors. However, the risk of HCV infection is significant, especially among high-risk groups (adjusted odds ratio, 2.0–3.6), when tattoos are applied in prison settings or by friends. Prevention interventions are needed to avoid the transmission of hepatitis C from tattooing and piercing in prisons, homes, and other potentially nonsterile settings. Youths also should be educated on the need to have tattoos and piercings performed under sterile conditions to avoid HCV infection. PMID:22291098

    Oral piercing can lead to complications and dentists are in a unique position to detect such complications. The purpose of this study was: (i) to assess the immediate and the long-term effects, on dental students, of a training programme about oral piercing knowledge; and (ii) to assess the immediate effect, on adolescents, of a single educational intervention session about oral piercing. A training programme for dental students (n = 66) was carried out in three phases. The last phase consisted of preparing and giving talks about oral piercing at schools, which was delivered by a random selection of dental students involved in the training programme. Dental students answered a questionnaire about oral piercing knowledge, before, immediately after (only the dental students included in the last phase) and 12 months after the training programme. Adolescents (n = 347) answered a survey about oral piercing knowledge before and after the talks. There were statistically significant differences in all comparison groups, except for the results in the 'before intervention' and in the '12 months after intervention' groups among dental students who had not prepared and given the talks to adolescents. Knowledge about oral piercing significantly improved among adolescents when comparing results before (mean questionnaire score = 3.0) and after (mean questionnaire score = 6.2) the talks. Oral piercing educational intervention had a favourable impact on adolescents and dental students, particularly among those who were more involved in the learning process. © 2017 FDI World Dental Federation.

  9. Joule-Thomson effect in a Pierce electron gun

    Batalin, V.A.

    1982-01-01

    A model which can be investigated both by means of the system of Vlasov equations and by means of ideal gas state equation is proposed for evaluation of emittance growth in the Pierce electron gun of electron beam with the limiting small distribution rate and intended for electron cooling facilities. The assumption has been made that transverse emittance growth is different from the zero. Thermodynamical approach to the problem of electron beam propagation permits to evaluate the increase of its emittance. It is shown that the increase of the electron beam emittance in the Pierce electron gun is similar to Joule-Thompson effect for gases. The effect increases with the decrease of the beam initial temperature. The increase of the emittance can become essential even in hte perfect (without aberration) Pierce optics at beam transverse temperature of the order of 0.1 eV

    1997-01-01

    A study is made of the radiative Pierce instability of a relativistic electron beam propagating in a waveguide in the presence of an infinitely strong magnetic field. The perturbation theory is used to find the growth rates and conditions of instability over a broad range of the beam current. It is shown that, under the Pierce boundary conditions, the instability is Raman in nature, and there is no current threshold for the instability. This allows the instability saturation level to be accurately determined from the condition for the violation of the Cherenkov resonance and the radiation efficiency to be estimated

    1992-01-01

    The extended Pierce diode is similar to the standard (or classical) Pierce diode, but has passive circuit elements in place of the short circuit between the electrodes. This device is important as an approximation to real bounded plasma systems. It consists of two parallel plane electrodes (an emitter located at x=0 and a collector located at x=l) and a collisionless cold electron beam travelling between them. The electrons are neutralized by a background of comoving massive ions. This situation is analysed in this paper and new equilibrium double layer (DL) plasma structures are obtained.

    The non-uniform (non-linear) equilibria of the classical (short circuit) Pierce diode and the extended (series RLC external circuit) Pierce diode are described theoretically, and explored via computer simulation. It is found that most equilibria are correctly predicted by theory, but that the continuous set of equilibria of the classical Pierce diode at α = 2π are not observed.

    In this work instrumental neutron activation analysis was applied to analyse elemental composition of commercial gold coated ear piercing substrate and metals present in their corrosion products. The cytotoxic effect was also verified in these corrosion product extracts, probably, due to the lixiviation of Ni present in high quantity in their substrates. The analysis of gold coated ear piercing surfaces by scanning electron microscopy before and after the corrosion test showed coating defects and the occurrence of corrosion process. (author)

    Oral piercing has become common in young adults in recent years. Adolescents are characterized by a compulsive tendency to distinguish themselves from the rest; differences in clothes, hairstyle, or "decorative" details are used to this effect, based on highly-diverse criteria. Dental health-care professionals need to be aware of the procedures and risks involved with oral piercings and the social and psychological reasons that lead people to engage in this practice, regardless of the risks. The present article addresses oral mutilation practices, specifically from the oral health perspective, as it is of concern to dental professionals due to the health risks and oral complications associated with such practices. The various oral ornaments, piercing sites, and their implications, orally, as well as systemically, have been discussed. © 2011 Blackwell Publishing Asia Pty Ltd.

    Piercing is popular among young people, who view this practice as a sign of marginality, beauty, or group identity. This study is performed on healthy individuals with oral and facial piercings. Seventy oral and facial piercings were evaluated (17 in the tongue, 13 in the lower lip, 18 in the nostril, 7 in the eyebrow, and 15 in the ear). A specifically designed protocol was used to assess possible complications (inflammatory reactions, pain, dental alterations). Nonparametric tests were used for the statistical analysis of the results. The general complications recorded comprised pain (60% of cases), inflammatory reactions (34.3%), bleeding (24%), dental fractures or fissures (20%), and gingival damage (26.7%). Tongue piercing is associated with pain, inflammatory reactions, and dental problems.

    To determine the prevalence of oral and/or peri-oral piercings in young adults based on a systematic review of the available literature. The MEDLINE-PubMed, Cochrane-CENTRAL and EMBASE databases were comprehensively searched through April 2012 to identify appropriate studies. The prevalence of oral and/or peri-oral piercings was evaluated in the general population, as well as by gender and by anatomical site. An independent screening of 1711 unique titles and abstracts resulted in 13 publications that met the eligibility criteria. In total, 11 249 participants (mean age, 20.6 years) were questioned and/or examined for oral and/or peri-oral piercings. In the studies that provided information concerning the presence of oral and/or peri-oral piercings, the prevalence varied from 0.8% to 12%, resulting in a mean prevalence of 5.2%. When examined based on anatomical site, the most common sites were the tongue (a prevalence of 5.6%), followed by the lip (1.5%). Oral piercings were more prevalent in women (5.6%) than men (1.6%). Among the populations that were studied, oral and/or peri-oral piercings were observed in a relatively small percentage (5.2%) of young adults. The prevalence was approximately four times higher among females when compared with males. On the basis of the literature, the tongue was the most common oral site for a piercing. Dental care professionals are in an ideal position to offer information regarding safe piercings and to provide advice regarding oral hygiene, aftercare and possible complications. © 2012 John Wiley & Sons A/S.

    2007-01-01

    Auricular or high helical ear piercing is an increasingly widespread fashion trend that is associated with an increased risk of potentially serious post-piercing complications such as auricular perichondritis. An 11-year-old girl developed severe auricular perichondritis following piercing of the upper helical cartilage of her ear at a hairdressing salon. Four days post piercing, she returned to the same salon for a haircut during which the pierced site was manipulated. She presented to her family physician and was treated unsuccessfully with oral cephalexin. She was then referred to an infectious diseases consultant and received antipseudomonal intravenous antibiotics with subsequent resolution. She also required debridement and removal of necrotic cartilage. Public health investigation evaluated potential sources of infection including the piercing gun, disinfectant solutions, and hair cutting spray water bottles. Final culture results of the ear helical aspirate grew Pseudomonas aeruginosa. Pseudomonas aeruginosa was also cultured from one of the water bottles used to wet her hair during the haircut. Although the pseudomonal strains from the water bottle were different than the infecting one, this contamination presents a potential source of wound infection. Damage to the helical cartilage caused by the piercing gun may also have contributed to this infection. Initial empiric antibiotic therapy for these kinds of infection must include anti-pseudomonal coverage. Auricular or high helical ear piercing using a piercing gun is not recommended.

    A systematic experiment is performed on the Buneman instability and the Pierce instability in a bounded plasma consisting of beam electrons and stationary ions. Current fluctuations are confirmed to be induced by the Buneman instability. On the other hand, the Pierce instability gives rise to a current limitation. The phenomena are well explained by Mikhailovskii's theory taking account of ion motion in a bounded plasma. (author)

  4. Obituary: A. Keith Pierce, 1918 - 2005

    Livingston, William Charles

    2006-12-01

    A. Keith Pierce was a solar astronomer who will be remembered for bringing the physics lab to the telescope and for his design of the world's largest solar telescope, the 1.5-meter McMath Telescope on Kitt Peak in Arizona. Born in Lincoln, Nebraska, he died of cancer in Tucson on 11 March 2005. He was eighty-six. His father, Tracy Pierce, had gone to graduate school in Berkeley, California, with a major in mathematics and a minor in astronomy. Fellow students of his class included Seth Nicholson and Donald Shane, people who were later to influence young Keith's life. Tracy Pierce received an appointment as an instructor, later Professor, of mathematics at the University of Nebraska in Lincoln. In his spare time dad Tracy became something of a telescope nut, following "the bible" —Albert Ingall's A.T.M (Amateur Telescope Making). His enthusiasm rubbed off on his son. Seth Nicholson, who became a famous Mt. Wilson Observatory astronomer, and Donald Shane from Berkeley, both stayed at the Pierce home while on their Sigma Xi lecture tours. After two years at Lincoln, followed by two more at Berkeley, Keith had earned his bachelor's degree in astronomy. During World War II, Dr. Shane became personnel director at the E.O. Lawrence Radiation Lab and arranged for Keith to work there at the cyclotron. A crash program to produce U235 from U238 was under way. At a crucial point in 1942 the cyclotron turned out the sought-after material. Much celebration ensued among the Rad Lab leaders. During this gala, Keith was on the night-shift and pretty much on his own. It was then that he turned a valve to the right, when left was called for, and the entire system went down. Shortly thereafter he was sent to Oak Ridge for the duration of the war. He cannot have been thought of badly, however, because he was invited to the Trinity test in New Mexico. (He didn't go because of the pending birth of his first son, John.) The year 1945 found Keith back in Berkeley working on his Ph

    Full Text Available A diversidade cultural, representada pela utilização de tatuagens e piercings, possui variados impactos nos fenômenos sociais. No âmbito organizacional, sua gestão propicia potencialidades, especialmente como oportunidade para harmonizar ambientes corporativos e agregar valor competitivo. A pesquisa investiga a percepção sobre a empregabilidade de pessoas adeptas à tatuagens e piercings no contexto da gestão da diversidade cultural. Realizou-se pesquisa de campo com 8 empresários de uma cidade do interior do estado do Piauí, por meio de entrevistas semiestruturadas, analisadas com suporte na análise de conteúdo, especificamente, análise relacional. Com auxílio do software Atlas ti, categorizou-se as entrevistas em torno da gestão da diversidade cultural e duas subcategorias: cultura organizacional, formada pela dimensão valores sobre a diversidade e relações interpessoais; e resultados, formada pelas dimensões imagem e objetivos organizacionais. Constata-se que nas empresas do estudo não há gestão da diversidade, haja vista que os valores pessoais e organizacionais ainda não incorporaram valores culturais da diversidade. Em relação à empregabilidade, os objetivos institucionais refletidos nas políticas de gestão de pessoas, condicionam as competências, habilidades e atitudes profissionais ao atendimento de normas prescritas, reduzindo as possibilidades de gestão do potencial da diversidade na organização, em função do recrutamento e seleção de um perfil ideal. Acredita-se que pesquisas em outras contextos, inclusive de natureza comparativa, pode agregar novos pontos de vista e ampliar a discussão da gestão da diversidade no âmbito de sua afirmação como prática capaz de transformar organizações em espaços de maior acolhimento e mais competitivos

  7. The Pierce diode with an external circuit. I. Oscillations about nonuniform equilibria

    International Nuclear Information System (INIS)

    Lawson, W.S.

    1989-01-01

    The nonuniform (nonlinear) equilibria of the classical (short circuit) Pierce diode and the extended (series RLC external circuit) Pierce diode are described, and the spectrum of oscillations (stable and unstable) about these equilibria are worked out. It is found that only the external capacitance alters the equilibria, though all elements alter the spectrum. In particular, the introduction of an external capacitor destabilizes some equilibria that are marginally stable without the capacitor. Computer simulations are performed to test the theoretical predictions for the case of an external capacitor only. It is found that most equilibria are correctly predicted by theory, but that the continuous set of equilibria of the classical Pierce diode at Pierce parameters (α=ω/sub pL//v 0 ) that are multiples of 2π are not observed. This appears to be a failure of the simulation method under the rather singular conditions rather than a failure of the theory

  8. Daith Piercing in a Case of Chronic Migraine: A Possible Vagal Modulation

    Directory of Open Access Journals (Sweden)

    Angelo Cascio Rizzo

    2017-11-01

    Full Text Available Daith piercing is an ear piercing located at the crus of the helix, bilaterally. It is getting great consent on social media as alternative treatment in chronic migraine. No data about its efficacy and action are available in scientific literature so far. We present the case of a 54-year-old male patient suffering from refractory chronic migraine with medication-overuse, who substantially improved after bilateral ear daith piercing. His migraine was refractory to symptomatic as well as prophylactic therapies. He used to treat headaches with up to five symptomatic drugs per attack and had attempted several pharmacological preventive therapies, including Onabotulinumtoxin A. He also underwent detoxification treatments with intravenous steroids and diazepam, without durable benefit. At the time of daith piercing, the headache-related disability measures showed a HIT-6 score of 64, a MIDAS-score of 70, and a 11-point Box scale of 5. On his own free will, he decided to get a “daith piercing.” After that, he experienced a reduction of migraine attacks, which became very rare, and infrequent, less disabling episodes of tension-type headache (HIT-6 score of 56; MIDAS score of 27, 11-point Box scale of 3. Painkiller assumption has much decreased: he takes only one tablet of indomethacin 50 mg to treat tensive headaches, about four times per month. Beyond a placebo effect, we can speculate a vagal modulation as the action mechanism of daith piercing: a nociceptive sensory stimulus applied to trigeminal and vagal areas of the ear can activate ear vagal afferents, which can modulate pain pathways by means of projections to the caudal trigeminal nucleus, to the locus coeruleus and to the nucleus raphe magnus. Currently, daith piercing cannot be recommended as migraine treatment because of the lack of scientific evidence, the unquantified rate of failure and the associated risks with insertion. However, given the increasing but anecdotal evidence, we

  9. Circuit effects on pierce instabilities, and double-layer formation

    The role of the Pierce instability in the formation of double layers is considered and compared with that of the Buneman instability. Pierce instabilities have been identified in a double-layer experiment, where they lead to ion trapping. Here the effects of external circuit elements are considered. In the case of immobile ions the onset criteria are unaffected, but in the unstable range the growth rate is reduced by the external impedance. Required experimental values of the circuit elements are estimated. The possible relevance to computer simulations is noted. (Authors)

  11. In Vitro Study on the Adhesion and Colonization of Candida Albicans on Metal and Acrylic Piercings

    Stamenov N.

    2016-03-01

    Full Text Available Oral/perioral piercing may provide an ideal environment for adhesion and colonization of microorganisms. The aim of this study is to perform an “in vitro” research on the capabilities of adhesion of Candida albicans on oral piercings made of plastic and metal. Acrylic and metal piercings were incubated with Candida albicans and then were observed using scanning electron microscopy under different magnifications. A lot of irregularities and roughness were observed on the surface of the plastic piercing unlike the surface of the metal one, which is not so rough. Nevertheless, the number of Candida albicans colonies was considerably larger on the scanned metal surface in comparison to the plastic surface. In vitro the metal surface of the piercing creates better environment for the adhesion and colonization of microorganisms than the acrylic. This could be attributed to the electrostatic forces that most likely attract Candida albicans to the metal piercing in the early stages of biofilm formation.

  12. Process Monitoring and Fault Diagnosis for Piercing Production of Seamless Tube

    2016-01-01

    Full Text Available With the development of modernization, the application of seamless tube becomes widespread. As the first process of seamless tube, piercing is vital for the quality of the tube. The solid round billet will be transformed into a hollow shell after the piercing process. The defects of hollow shell cannot be cleared in the following process, so a monitoring model for the quality of the hollow shell is important. But the piercing process is very complicated, and a mechanism model is difficult to build between the qualities of the hollow shell and measurement variables. Furthermore, an intelligent model is needed. We established two piercing process monitoring and fault diagnosis models based on the multiway principal component analysis (MPCA model and the multistage MPCA model, respectively, and furthermore we made a comparison between these two concepts. We took three ways to divide the period based on process, K-means, and GA, respectively. Simulation experiments have shown that the multistate MPCA method has advantage over the MPCA method and the model based on the genetic algorithm (GA can monitor the process effectively and detect the faults.

    Full Text Available Today tongue piercing has become increasingly popular in the society. Several case reports associated with tongue piercing have presented various complications, such as tooth fracture, viral infection (HIV, Hepatitis B and C, herpes simplex, Epstein Barr, fungal infection (Candida spp, pain altered taste, edema, paresthesis, gingival recession, prolonged bleeding, contact dermatitis. However, there is no scientific evidence to reveal hispathological change in tongue piercing. The aim of this study is to investigate the inflammation response to tongue piercing in Spraque Dawley rats. Eighteen Sprague Dawley rats were divided into one control group of 3 untreated rats and three experimental groups of 5 rats each, according to the duration of tongue piercing until the end of 1st week (A, 6th week (B and 12th week (C. At the end of treatments, the rats were anesthetized and sacrifices. Paraffin embedded tongue specimens were prepared for histological examination with H&E stainig. The number of inflammatory cells (PMN leukocytes, lymphocytes, macrophages was counted under light microscope. All experimental procedures were carried out under approval of study protocol by the Health and Medical Research Ethics Committee, Faculty of Medicine, Gadjah Mada University, Yogyakarta. The results of this study indicated that the number of PMN leukocytes, lymphocytes, and macrophages was increasing to the 1st week after tongue piercing. The number of lymphocytes and macrohpages was still increasing after 6th and 12th weeks of piercing, but the bumber of PMN leukocytes, lymphocytes, and macrophages between the groups of 1st, 6th, and 12th weeks after piercing. It was concluded that tongue piercing induce inflammatory response for 12 weeks in Sprague Dawley rats.

  16. Finite ion velocity effects on the stability of Pierce-like diodes

    International Nuclear Information System (INIS)

    Kolinsky, H.; Schamel, H.

    1994-01-01

    The stability of Pierce-like plasma diodes is investigated for arbitrary ion injection velocities. A recently developed integral formalism that accounts for ion dynamical effects is applied to derive a generalized dispersion relation for electrostatic perturbations. Its evaluation exhibits several new features, such as the appearance of growing oscillatory modes, which become Pierce--Buneman modes in the limit of initially resting ions, and of weakly damped oscillatory modes, which become undamped ion plasma oscillations in this limit. The stability of this bounded plasma system is shown to be controlled by the new control parameter at signga=α(1+at signgm) 1/2 , where α is the Pierce parameter and at signgm≡m ev 2 e0 /m iv 2 i0 the ratio of electron and ion kinetic energy at the emitter

  17. The corrosion resistance of materials used for the manufacture of ear piercing studs

    Directory of Open Access Journals (Sweden)

    Correa, O. V.

    2003-12-01

    Full Text Available Nickel containing alloys have been widely used as substrates for the manufacture of studs used for ear piercing. Unfortunately, nickel has also been related to the development of allergic contact dermatitis caused by skin sensitization due to Ni2+ ions. Nickel ions can be leached out into the body fluids due to corrosion reactions. Defect free coatings are very difficult to produce, and therefore nickel free materials should be used as substrates of ear piercing studs, although the commercial alloys used usually contain this element. In this study, the corrosion resistance of two kinds of commercial studs prepared with nickel containing substrates and a titanium laboratory made stud was determined in a culture medium. The corrosion resistance of the studs was investigated by means of potentiodynamic polarization tests and electrochemical impedance spectroscopy as a function of immersion time in the culture medium. The elements that leached out into the medium due to corrosion reactions were analyzed by instrumental neutron activation analysis. The surfaces of the commercial gold-coated studs were examined by scanning electron microscopy and analyzed by energy dispersive spectroscopy, both before and after exposure to the culture medium. The cytotoxicity of the tested studs was also determined in the culture medium.

    Background Although published results are inconsistent, it has been suggested that tattooing and piercing are risk factors for HBV and HCV infections. To examine whether tattooing and piercing do indeed increase the risk of infection, we conducted a study among people with multiple tattoos and/or piercings in the Netherlands who acquired their tattoos and piercings in the Netherlands and/or abroad. Methods Tattoo artists, piercers, and people with multiple tattoos and/or piercings were recruited at tattoo conventions, shops (N = 182), and a biannual survey at our STI-outpatient clinic (N = 252) in Amsterdam. Participants were interviewed and tested for anti-HBc and anti-HCV. Determinants of HBV and HCV infections were analysed using logistic regression analysis. Results The median number of tattoos and piercings was 5 (IQR 2–10) and 2 (IQR 2–4), respectively. Almost 40% acquired their tattoo of piercing abroad. In total, 18/434 (4.2%, 95%CI: 2.64%–6.46%) participants were anti-HBc positive and 1 was anti-HCV positive (0.2%, 95%CI: 0.01%–1.29%). Being anti-HBc positive was independently associated with older age (OR 1.68, 95%CI: 1.03–2.75 per 10 years older) and being born in an HBV-endemic country (OR 7.39, 95%CI: 2.77–19.7). Tattoo- and/or piercing-related variables, like having a tattoo or piercing in an HBV endemic country, surface percentage tattooed, number of tattoos and piercings etc., were not associated with either HBV or HCV. Conclusions We found no evidence for an increased HBV/HCV seroprevalence among persons with multiple tattoos and/or piercings, which might be due to the introduction of hygiene guidelines for tattoo and piercing shops in combination with the low observed prevalence of HBV/HCV in the general population. Tattoos and/or piercings, therefore, should not be considered risk factors for HBV/HCV in the Dutch population. These findings imply the importance of implementation of hygiene guidelines in other countries. PMID

RESULTS: The median number of tattoos and piercings was 5 (IQR 2-10 and 2 (IQR 2-4, respectively. Almost 40% acquired their tattoo of piercing abroad. In total, 18/434 (4.2%, 95%CI: 2.64%-6.46% participants were anti-HBc positive and 1 was anti-HCV positive (0.2%, 95%CI: 0.01%-1.29%. Being anti-HBc positive was independently associated with older age (OR 1.68, 95%CI: 1.03-2.75 per 10 years older and being born in an HBV-endemic country (OR 7.39, 95%CI: 2.77-19.7. Tattoo- and/or piercing-related variables, like having a tattoo or piercing in an HBV endemic country, surface percentage tattooed, number of tattoos and piercings etc., were not associated with either HBV or HCV. CONCLUSIONS: We found no evidence for an increased HBV/HCV seroprevalence among persons with multiple tattoos and/or piercings, which might be due to the introduction of hygiene guidelines for tattoo and piercing shops in combination with the low observed prevalence of HBV/HCV in the general population. Tattoos and/or piercings, therefore, should not be considered risk factors for HBV/HCV in the Dutch population. These findings imply the importance of implementation of hygiene guidelines in other countries.

    2007-02-27

    An oscillator circuit is disclosed which can be formed using discrete field-effect transistors (FETs), or as a complementary metal-oxide-semiconductor (CMOS) integrated circuit. The oscillator circuit utilizes a Pierce oscillator design with three inverter stages connected in series. A feedback resistor provided in a feedback loop about a second inverter stage provides an almost ideal inverting transconductance thereby allowing high-Q operation at the resonator-controlled frequency while suppressing a parasitic oscillation frequency that is inherent in a Pierce configuration using a "standard" triple inverter for the sustaining amplifier. The oscillator circuit, which operates in a range of 10 50 MHz, has applications for use as a clock in a microprocessor and can also be used for sensor applications.

    After an acute sexual assault, children and adolescents often present for medical evaluation and treatment. Physicians have an important role in both the medical and legal components of these cases. Careful physical examination and questioning are important in determining the origin of the trauma. In the presented case report, genital trauma after an acute sexual assault was noted and attributed to the alleged offender's penis piercing. The genital trauma caused by the piercing provided physical evidence linking offender to victim and may have implications for the victim's risk of HIV infection and other blood borne pathogens.

    A self-piercing rivet (SPR) is a mechanical component for joining dissimilar material sheets such as those of aluminum alloy and steel. Unlike conventional rivets, the SPR directly pierces sheets without the need for drilling them beforehand. However, the regular SPR can undergo buckling when it pierces a high-strength steel sheet, warranting the design of a helical SPR. In this study, the joining and forging processes using the helical SPR were simulated using the commercial FEM code, DEFORM-3D. High-tensile-strength steel sheets of different strengths were joined with aluminum alloy sheets using the designed helical SPR. The simulation results were found to agree with the experimental results, validating the optimal design of a helical SPR that can pierce high-strength steel sheets

    2017-12-01

    Maintaining healthy teeth and soft oral tissue is important. Clinical research has shown manual toothbrushes with end-rounded filaments to cause significantly less gingival abrasions than those without end-rounding. Tapered filaments are an alternative to end-rounded filaments, but there is no solid evidence for their effectiveness. For the interdental spaces that the toothbrush doesn't reach, the use of special oral hygiene aids is advised. Clinical studies of gingivitis patients have shown that both interdental brushes and plastic-rubber bristles reduce gingivitis after 4 weeks of use. Plastic-rubber bristles result in a significant improvement in the tendency for interdental bleeding compared with interdental brushes, and they cause less abrasion of the gingiva. Other factors that can potentially traumatise soft and hard oral tissue are oral piercings. Wearing oral piercings is not without risk. Tongue and lip piercings are associated with the risk of gingival recession, and tongue piercings are associated with tooth fractures. To prevent the risk of complications, patients should be discouraged from wearing oral piercings.

    The authors present a man who underwent chest augmentation and nipple piercing. The patient developed chronic nipple infection, which led to unnecessary invasive diagnostic procedures, serious implant infection, and eventually urgent explantation. This unfavorable scenario illustrates the distinct features of the procedure in men, which includes close proximity of the nipple to the implant and reduced awareness by health care providers. Based on this case the authors recommend avoiding nipple piercing in men with chest implants.

  11. The corrosion resistance of materials used for the manufacture of ear piercing studs

    Nickel containing alloy shave been widely used as substrates for the manufacture of studs used for ear piercing. Unfortunately, nickel has also been related to the development of allergic contact dermatitis caused by skin sensitization due to Ni''2+ ions. Nickel ions can be leached out into the body fluids due to corrosion reactions. Defect free coatings are very difficult to produce, and therefore nickel free materials should be used as substrates of ear piercing studs, although the commercial alloys used usually contain this element. In this study, the corrosion resistance of two kinds of commercial studs prepared with nickel containing substrates and a titanium laboratory made stud was determined in a culture medium. The corrosion resistance of the studs was investigated by means of potentiodynamic polarization tests and electrochemical impedance spectroscopy as a function of immersion time in the culture medium. The elements that leached out into the medium due to corrosion reactions were analyzed by instrumental neutron activation analysis. The surfaces of the commercial gold-coated studs were examined by scanning electron microscopy and analyzed by energy dispersive spectroscopy, both before and after exposure to the culture medium. The cytotoxicity of the tested studs was also determined in the culture medium. (Author) 10 refs

Drawing on the recent ‘sensorial turn’ within anthropology, I suggest an approach which goes beyond considerations of the symbolism of body ornaments and analyses how the infliction of pain they involve can be manipulated to serve social ends at a local level. Also discussed is the use of labrets within global ‘mediascapes’ (Appadurai 1996 by Kayapo and Northwest Coast groups in the context of self-representation and the politicization of ‘culture’ (Wright 1998.

    The results of investigations are presented concerning the accuracy of geometrical dimensions of thick-walled sleeves produced by piercing on a 100-ton trio screw rolling mill MISiS with three schemes of fixing and centering the rod. The use of a spherical thrust journal for the rod and of a long centering bushing makes it possible to diminish the non-uniformity of the wall thickness of the sleeves by 30-50%. It is established that thick-walled sleeves with accurate geometrical dimensions (nonuniformity of the wall thickness being less than 10%) can be produced if the system sleeve - mandrel - rod is highly rigid and the rod has a two- or three-fold stability margin over the length equal to that of the sleeve being pierced. The process of piercing is expedient to be carried out with increased angles of feed (14-16 deg). Blanks have been made from steel 12Kh1MF

    The use of chewing-gum and piercing has become common among adolescents and might result in increased oral muscle activity and overloading. Aim To investigate the frequency of oral piercing and parafunctions in relation to symptoms of temporomandibular disorders (TMD) among adolescents. One hundred and twenty-four third level high school students, living either in a city or in a small town, enrolled in either science or media programmes, were included. The students completed a questionnaire regarding different parafunctions and symptoms of TMD. A clinical examination of the temporomandibular system and estimation of the tooth wear was performed in 116 students. Chewing-gum was used by 86% of the students (25% with a daily use) and 14% had an oral piercing. The science students used more chewing gum than the media students (p = 0.008), while the media students had more piercings (p headache, 18% for clicking, 7% for facial pain and 6% for difficulty to open wide. Girls reported more headaches (p = 0.007) and more severe symptoms (p = 0.003), had more medical consultations and used more analgesics (both p headache (p temporomandibular joints and muscles (both p headache and muscle tenderness (both p headache (p < 0.05) and tooth wear (p = 0.004).

    To describe the characteristics of body modification among adolescents and to determine whether adolescents who engage in body modification are more likely to screen positive for alcohol and other drug problems than those who do not. Adolescents aged 14 to 18 years presenting to an urban adolescent clinic for routine health care completed a questionnaire about body modification and a substance use assessment battery that included the 17-item Problem Oriented Screening Instrument for Teenagers Alcohol/Drug Use and Abuse Scale (POSIT-ADS). Body modification was defined as piercings (other than one pair of bilateral earlobe piercings in females), tattoos, scarification, and branding. Problem substance use was defined as a POSIT-ADS score > or =1. Data were analyzed using logistic regression to determine whether the presence of body modification was an independent predictor of problem substance use. The 210 participants had a mean (+/- SD) age of 16.0 (+/- 1.4) years and 63% were female. One hundred adolescents (48%) reported at least one body modification; girls were more likely than boys to have body modification (59% vs. 28%, p branding; 21 (10%) had more than one type of body modification. These were in a variety of locations, most commonly the ear and the nose (piercings) or the extremities (tattoos). One-third of the sample (33%) screened positive for problem substance use on the POSIT-ADS questionnaire. Controlling for age, adolescents with body modification had 3.1 times greater odds of problem substance use than those without body modification (95% CI 1.7, 5.8). Body modification was associated with self-reported problem alcohol and other drug use among middle adolescents presenting for primary care. More research is needed to determine the clinical and sociocultural significance of body modification and its relationship to substance use in this population.

    Yamamotová, A; Hrabák, P; Hříbek, P; Rokyta, R

    2017-12-30

    In recent years, epidemiological data has shown an increasing number of young people who deliberately self-injure. There have also been parallel increases in the number of people with tattoos and those who voluntarily undergo painful procedures associated with piercing, scarification, and tattooing. People with self-injury behaviors often say that they do not feel the pain. However, there is no information regarding pain perception in those that visit tattoo parlors and piercing studios compared to those who don't. The aim of this study was to compare nociceptive sensitivity in four groups of subjects (n=105, mean age 26 years, 48 women and 57 men) with different motivations to experience pain (i.e., with and without multiple body modifications) in two different situations; (1) in controlled, emotionally neutral conditions, and (2) at a "Hell Party" (HP), an event organized by a piercing and tattoo parlor, with a main event featuring a public demonstration of painful techniques (burn scars, hanging on hooks, etc.). Pain thresholds of the fingers of the hand were measured using a thermal stimulator and mechanical algometer. In HP participants, information about alcohol intake, self-harming behavior, and psychiatric history were used in the analysis as intervening variables. Individuals with body modifications as well as without body modifications had higher thermal pain thresholds at Hell Party, compared to thresholds measured at control neutral conditions. No such differences were found relative to mechanical pain thresholds. Increased pain threshold in all HP participants, irrespectively of body modification, cannot be simply explained by a decrease in the sensory component of pain; instead, we found that the environment significantly influenced the cognitive and affective component of pain.

    A convenience sample of 60 subjects (27 male; 33 female) with tongue piercings (case group) and 120 subjects (43 male; 77 female) without tongue piercings (control group), ranging in age from 13 to 28 years, were identified from a mix of races living in a geographic area of low socioeconomic status in Brazil. Subjects were recruited from school groups and university centers between January 2008 and March 2009. For each case, 2 controls were selected on a consecutive basis from the same school according to criteria that included age, gender, smoking, and previous orthodontic treatment. Exclusion criteria included individuals with systemic diseases that might compromise the immune system, as well as antibiotics within 3 months or other medications that could affect the gingival tissues. The key study factor was the use or nonuse of tongue piercings (jewelry). The analysis compared periodontal parameters, such as the occurrence, location, and severity of gingival recession, in subjects with and without tongue jewelry. Gingival recession in the anterior lingual mandibular region was assessed as the primary outcome measure. The study sample was divided according to the presence or absence of gingival recession as well as the severity (1-2, 3, and ≥ 4 mm) of gingival recession. The average age of subjects was similar in the case and control groups (18.9 versus 17.7 years, respectively). Fractures of the anterior teeth were present significantly more frequently in cases than controls (26.7% versus 11.7%, respectively; P piercings (OR = 11.0, 95% confidence interval [CI] 5.02-24.09, P <.001). The severity of recession in this region was also significantly higher (calculated using an ordinal scale) in cases than in controls (P < .001). The final multivariate logistic regression model for occurrence of gingival recession included the variables tongue jewelry (yes/no), age, male gender, and the presence of bleeding on probing in the anterior region.

    2014-01-01

    Background A system providing disabled persons with control of various assistive devices with the tongue has been developed at Aalborg University in Denmark. The system requires an activation unit attached to the tongue with a small piercing. The aim of this study was to establish and evaluate a safe and tolerable procedure for medical tongue piercing and to evaluate the expected and perceived procedural discomfort. Methods Four tetraplegic subjects volunteered for the study. A surgical protocol for a safe insertion of a tongue barbell piercing was presented using sterilized instruments and piercing parts. Moreover, post-procedural observations of participant complications such as bleeding, edema, and infection were recorded. Finally, procedural discomforts were monitored by VAS scores of pain, changes in taste and speech as well as problems related to hitting the teeth. Results The piercings were all successfully inserted in less than 5 min and the pain level was moderate compared with oral injections. No bleeding, infection, embedding of the piercing, or tooth/gingival injuries were encountered; a moderate edema was found in one case without affecting the speech. In two cases the piercing rod later had to be replaced by a shorter rod, because participants complained that the rod hit their teeth. The replacements prevented further problems. Moreover, loosening of balls was encountered, which could be prevented with the addition of dental glue. No cases of swallowing or aspiration of the piercing parts were recorded. Conclusions The procedure proved simple, fast, and safe for insertion of tongue piercings for tetraplegic subjects in a clinical setting. The procedure represented several precautions in order to avoid risks in these susceptible participants with possible co-morbidity. No serious complications were encountered, and the procedure was found tolerable to the participants. The procedure may be used in future studies with tongue piercings being a

    Blanking and piercing are manufacturing processes by which certain geometrical shapes are sheared off a sheet metal. If the sheared off part is the one required, the processes referred to as blanking and if the remaining part in the sheet is the one required, the process is referred to as piercing. In this paper, the theory and practice of these processes are reviewed and discussed The main parameters affecting these processes are presented and discussed. These include: the radial clearance percentage, punch and die geometrical parameters, for example punch and die profile radii. The abovementioned parameters on the force and energy required to effect blanking together with their effect on the quality of the products are also presented and discussed. Recent experimental results together with photomacrographs and photomicrographs are also included and discussed.

    Full Text Available Conventionally, intracytoplasmic sperm injection (ICSI in the mouse is conducted with piezo-drills that use a droplet of mercury for damping. The use of mercury causes concerns of toxicity and contamination. Although Fluorinert can be used as a substitute for mercury to reduce piezo-drill’s lateral vibration, the damping effect is not as satisfactory as mercury. In this work, a modified piezo-drill without using mercury was developed for the cellular piercing of mouse oocytes. Experimentally, appropriate parameters of driving voltage and frequency were obtained for the penetration of the zona pellucida of mouse oocytes. Furthermore, the lateral vibration of the injection pipette is lower than 1 μm in deionized water, which is not observable at 400 magnificence. With the piezo-drill without using mercury, the system performs the cellular piercing of mouse oocytes with a maximum cleavage rate of 94.7% (n = 117.

    Blanking and piercing are manufacturing processes by which certain geometrical shapes are sheared off a sheet metal. If the sheared off part is the one required, the processes referred to as blanking and if the remaining part in the sheet is the one required, the process is referred to as piercing. In this paper, the theory and practice of these processes are reviewed and discussed The main parameters affecting these processes are presented and discussed. These include: the radial clearance percentage, punch and die geometrical parameters, for example punch and die profile radii. The above mentioned parameters on the force and energy required to effect blanking together with their effect on the quality of the products are also presented and discussed. Recent experimental results together with photomacrographs and photomicrographs are also included and discussed. Finally, the effect of punch and die wear on the quality of the blanks is also given and discussed. (author)

  16. Ventilation Inception and Washout, Scaling, and Effects on Hydrodynamic Performance of a Surface Piercing Strut

    Harwood, Casey; Young, Yin Lu; Ceccio, Steven

    2014-11-01

    High-lift devices that operate at or near a fluid free surface (such as surface-piercing or shallowly-submerged propellers and hydrofoils) are prone to a multiphase flow phenomenon called ventilation, wherein non-condensable gas is entrained in the low-pressure flow, forming a cavity around the body and dramatically altering the global hydrodynamic forces. Experiments are being conducted at the University of Michigan's towing tank using a canonical surface-piercing strut to investigate atmospheric ventilation. The goals of the work are (i) to gain an understanding of the dominant physics in fully wetted, partially ventilated, and fully ventilated flow regimes, (ii) to quantify the effects of governing dimensionless parameters on the transition between flow regimes, and (iii) to develop scaling relations for the transition between flow regimes. Using theoretical arguments and flow visualization techniques, new criteria are developed for classifying flow regimes and transition mechanisms. Unsteady transition mechanisms are described and mapped as functions of the governing non-dimensional parameters. A theoretical scaling relationship is developed for ventilation washout, which is shown to adequately capture the experimentally-observed washout boundary. This material is based upon work supported by the National Science Foundation Graduate Student Research Fellowship under Grant No. DGE 1256260. Support also comes from the Naval Engineering Education Center (Award No. N65540-10-C-003).

  17. The Pierce-diode approximation to the single-emitter plasma diode

    The possibility of modeling fast processes in the collisionless single-emitter plasma diode (Knudsen diode with surface ionization, KDSI) by means of the Pierce-diode is studied. The KDSI is of practical importance in that it is an almost exact model of thermionic energy converters (TICs) in the collisionless regime and can also be used to model low-density Q-machines. At high temperatures, the Knudsen TIC comes close to the efficiency of the Carnot cycle and hence is the most promising converter of thermal to electric energy. TICs can be applied as component parts in high-temperature electronics. It is shown that normalizations must be chosen appropriately in order to compare the plasma characteristics of the two models: the KDSI and the Pierce-diode. A linear eigenmode theory of the KDSI is developed. For both nonlinear time-independent states and linear eigenmodes without electron reflection, excellent agreement is found between the analytical potential distributions for the Pierce-diode and the corresponding numerical ones for the KDSI. For the states with electron reflection, the agreement is satisfactory in a qualitative sense. A full classification of states of both diodes for the regimes with and without electron reflection is presented. The effect of the thermal spread in electron velocities on the potential distributions and the (ε,η) diagrams is analyzed. Generally speaking, the methodology developed is usefully applicable to a variety of systems in which the electrons have beam-like distributions

    The brown planthopper (BPH, Nilaparvata lugens) is a destructive, monophagous, piercing-sucking insect pest of rice. Previous studies indicated that jasmonic acid (JA) positively regulates rice defense against chewing insect pests but negatively regulates it against the piercing-sucking insect of BPH. We here demonstrated that overexpression of allene oxide cyclase (AOC) but not OPR3 (cis-12-oxo-phytodienoic acid (OPDA) reductase 3, an enzyme adjacent to AOC in the JA synthetic pathway) significantly increased rice resistance to BPH, mainly by reducing the feeding activity and survival rate. Further analysis revealed that plant response to BPH under AOC overexpression was independent of the JA pathway and that significantly higher OPDA levels stimulated rice resistance to BPH. Microarray analysis identified multiple candidate resistance-related genes under AOC overexpression. OPDA treatment stimulated the resistance of radish seedlings to green peach aphid Myzus persicae, another piercing-sucking insect. These results imply that rice resistance to chewing insects and to sucking insects can be enhanced simultaneously through AOC-mediated increases of JA and OPDA and provide direct evidence of the potential application of OPDA in stimulating plant defense responses to piercing-sucking insect pests in agriculture. © The Author 2014.

    2017-04-01

    Full Text Available A mathematical abstraction and three-dimensional modeling method of three-dimensional woven fabric structure was developed for the fine weave pierced fabric, taking parametric continuity splines as the track function of tow. Based on the significant parameters of fine weave pierced fabric measured by MicroCT, eight kinds of the three-dimensional digital models of the fabric structure were established with two kinds of tow sections and four kinds of tow trajectory characteristic functions. There is a good agreement between the three-dimensional digital models and real fabric by comparing their structures and porosities. This mathematical abstraction and three-dimensional modeling method can be applied in micro models for sub unit cell and macro models for macroscopic scale fabrics, with high adaptability.

    In the course of prevention of infectious diseases the Public Health office of the city of Bremen has made increase efforts to improve hygienic conditions in tattoo and piercing studios. Defined and practicable hygienic standards have been developed and formulated for and in cooperation with the studios. Supported by intense personal counselling of the studios the hygienic standards are now--after 6-9 months--widely accepted and increasingly observed in practice. This programme has been--as a crucial point--supplemented by intense information for the general public and the customers of the studios in order to support (and control) the practice of hygienic standards in tattooing and piercing also from this point of view.

  4. Intermittent many-body dynamics at equilibrium

    The equilibrium value of an observable defines a manifold in the phase space of an ergodic and equipartitioned many-body system. A typical trajectory pierces that manifold infinitely often as time goes to infinity. We use these piercings to measure both the relaxation time of the lowest frequency eigenmode of the Fermi-Pasta-Ulam chain, as well as the fluctuations of the subsequent dynamics in equilibrium. The dynamics in equilibrium is characterized by a power-law distribution of excursion times far off equilibrium, with diverging variance. Long excursions arise from sticky dynamics close to q -breathers localized in normal mode space. Measuring the exponent allows one to predict the transition into nonergodic dynamics. We generalize our method to Klein-Gordon lattices where the sticky dynamics is due to discrete breathers localized in real space.

    Highlights: ► We investigated the fracture mechanism of AA7278-T6 aluminium self-piercing rivets. ► Fracture of AA 7278-T6 rivets during the riveting process is a complex phenomenon. ► Microstructure of AA7278-T6 has significant influence on the fracture mechanism. ► Increasing friction will change the deformation mode of the rivet. - Abstract: The present paper investigates the fracture mechanisms of AA7278-T6 aluminium self-piercing rivets under compression during the riveting process. First, a microstructure investigation was conducted to disclose the grain structure and the particle distribution of the extruded aluminium alloy. Transmission electron micrographs revealed precipitate free zones along grain boundaries. Uniaxial tensile tests in three different directions with respect to the extrusion direction revealed anisotropy of the alloy in strength and ductility and a change in fracture mode with tensile direction. The behaviour of the alloy under compression was studied experimentally using upsetting tests and self-piercing riveting tests. Micrographs of the deformed specimens provided insight into the influence of the microstructure on the deformation and fracture of the alloy under compression. Second, numerical analyses were carried out using a 2-D axisymmetric model in LS–DYNA in an attempt to investigate the role of different physical variables on the final failure of the rivet. The numerical results revealed that constituent particles, precipitate free zones, and friction between the rivet and plates are important for strain localisation and fracture in the rivet

    2013-03-01

    Full Text Available A thorough analysis of the cuticular parts of tardigrade feeding apparatuses was performed in order to provide a more complete understanding of their evolution and their potential homologies with other animal phyla (e.g. Cycloneuralia and Arthropoda. The buccal- pharyngeal apparatuses of eight species belonging to both Eutardigrada and Heterotardigrada were studied using light and scanning electron microscopy. This study supports and completes a previous study on the relationships between form and function in the buccalpharyngeal apparatus of eutardigrades. The common sclerified structures of the tardigrade buccal-pharyngeal apparatus are: a buccal ring connected to a straight buccal tube, a buccal crown, longitudinal thickenings within the pharynx, and a stylet system composed of piercing stylets within stylet coats, and stylet supports. Specifically, heterotardigrades (Echiniscoidea have a narrow buccal tube; long piercing stylets, each with a longitudinal groove, that cross one another before exiting the mouth; pharyngeal bars and secondary longitudinal thickenings within the pharynx. In contrast, eutardigrades have stylets which are shorter than the buccal tube; Parachela have pharyngeal apophyses and placoids within the pharynx, while Apochela lack a buccal crown and cuticular thickenings within the pharynx, the buccal tube is very wide, and the short stylets are associated with triangular-shaped stylet supports. In both classes, when the piercing stylet tips emerge from the mouth to pierce food, the buccal tube opening is almost completely obstructed, which may hinder food uptake. In heterotardigrades, the crossing of the piercing stylets may further decrease food uptake, however this disadvantage may have been reduced in echiniscids by the evolution of a long buccal tube and long stylets able to run more parallel to the buccal tube. In contrast, eutardigrades evolved different strategies. In the order Apochela and in several

  9. Experimental investigation of piercing of high-strength steels within a critical range of slant angle

    Deep drawn parts often do have complex designs and, therefore, must be trimmed or punched subsequently in a second stage. Due to the complex part geometry, most punching areas do reveal critical slant angle (angle between part surface and ram movement direction) different to perpendicular direction. Piercing within a critical range of slant angle may lead to severe damage of the cutting tool. Consequently, expensive cam units are required to transform the ram moving direction in order to perform the piercing process perpendicularly to the local part surface. For modern sheet metals, however, the described critical angle of attack has not been investigated adequately until now. Therefore, cam units are used in cases in which regular piercing with high slant angle wouldn’t be possible. Purpose of this study is to investigate influencing factors and their effect on punch damage during piercing of high strength steels with slant angles. Therefore, a modular shearing tool was designed, which allows to simply switch die parts to vary cutting clearance and cutting angle. The target size of the study is to measure the lateral deviation of the punch which is monitored by an eddy current sensor. The sensor is located in the downholder and measures the lateral punch deviation in-line during manufacturing. The deviation is mainly influenced by slant angle of workpiece surface. In relation to slang angle and sheet thickness the clearance has a small influence on the measured punch deflection.

    Complete text of publication follows. Gold is known as a metal having little or no toxicity and it has been widely used for coating studs for ear piercing. However, for some people gold coated studs have caused serious allergy and inflammation problems. After piercing, the studs are usually kept in the ear lobes for at least one week, and during this period the stud surfaces in contact with the body fluids have caused swelling, pain and redness of the skin. Consequently, it is of great interest to evaluate if elements from the metallic substrate underneath the gold coatings migrate to the body fluids due to the corrosion and the presence of defects in gold coatings. The solutions for corrosion test were obtained by placing the gold coated studs in contact with the solutions of NaCl and of culture medium. Elemental analyses of these solutions by radioanalytical method of neutron activation analysis indicated the occurrence of substrate corrosion since the elements Cr, Fe, Ni and Zn were found in these solutions. These elements are substrate material components of alloys used to make the studs and they were quantified by X-ray fluorescence analysis. The defects of the coatings were also detected by scanning electron microscopy and energy dispersive spectroscopy analysis of the gold coated studs before and after the corrosion tests. Cytotoxicity studies indicated that after corrosion test the solution used was toxic in the culture cell assay. Among the elements quantified in the test solutions, Ni is considered responsible for most of allergic reactions. Results obtained in this work indicated the necessity to improve quality control of the coating process of studs and in the appropriate choice of material used as substrate

    2018-03-01

    Full Text Available The suction side of a surface piercing hydrofoil, as a section of a Surface Piercing Propeller (SPP, is usually exposed to three phases of flow consisting air, water, and vapour. Hence, ventilation and cavitation pattern of such section during the initial phase of water entry plays an essential role for the propeller’s operational curves. Accordingly, in the current paper a numerical simulation of a simple surface piercing hydrofoil in the form of an oblique wedge is conducted in three-phase environment by using the coupled URANS and VOF equations. The obtained results are validated against water entry experiments and super-cavitation tunnel test data. The resulting pressure curves and free surface profiles of the wedge water entry are presented for different velocity ratios ranging from 0.12 to 0.64. Non-dimensional forces and efficiency relations are defined in order to present the wedge water entry characteristics. Congruent patterns are observed between the performance curves of the propeller and the wedge in different fully ventilated or partially cavitated operation modes. The transition trend from fully ventilated to partially cavitated operation of the surface piercing section of a SPP is studied and analyzed through wedge’s performance during the transitional period.

    Self-piercing riveting (SPR) has become a significant joining technique for the automotive applications of aluminium sheets. Quality control in this locale has progressed at an altogether more leisurely rate than other areas of mechanical joining (e.g. spotweld) and is underdeveloped. Testing the quality mechanical interlock is often achieved by destructive testing, which results in material and time wastage. The solution is online monitoring of the self-piercing riveting process to provide non-destructive testing of the mechanical interlock. Introducing sensors into the process facilitates real time data acquisition, which can be used to determine the quality of the joint

    Tungsten alloys have been widely used in the production of armour-piercing (AP) penetrators for defense purposes for the past 40 years. In recent years, however, depleted uranium (DU) has also been utilised for this application. Both materials exhibit high density and strength, two properties necessary for kinetic-energy projectiles to penetrate armour on tanks and other vehicles. The facts, however, support the view that tungsten can and should be utilised as the primary material for most armour-defeating ordnance applications. (author)

    The shells of molluscs survive well in many sedimentary contexts and yield information about the diet of prehistoric humans. They also yield evidence of symbolic behaviours through their use as beads for body adornments. Researchers often analyse the location of perforations in shells to make judgements about their use as symbolic objects (e.g., beads), the assumption being that holes attributable to deliberate human behaviour are more likely to exhibit low variability in their anatomical locations, while holes attributable to natural processes yield more random perforations. However, there are non-anthropogenic factors that can cause perforations in shells and these may not be random. The aim of the study is compare the variation in holes in shells from archaeological sites from the Old World with the variation of holes in shells pierced by mollusc predators. Three hundred and sixteen scientific papers were retrieved from online databases by using keywords, (e.g., 'shell beads'; 'pierced shells'; 'drilling predators'); 79 of these publications enabled us to conduct a systematic review to qualitatively assess the location of the holes in the shells described in the published articles. In turn, 54 publications were used to assess the location of the holes in the shells made by non-human predators. Almost all archaeological sites described shells with holes in a variety of anatomical locations. High variation of hole-placement was found within the same species from the same site, as well as among sites. These results contrast with research on predatory molluscs, which tend to be more specific in where they attacked their prey. Gastropod and bivalve predators choose similar hole locations to humans. Based on figures in the analysed articles, variation in hole-location on pierced shells from archaeological sites was similar to variation in the placement of holes created by non-human animals. Importantly, we found that some predators choose similar hole locations to

    A Pierce-type dispersion relation is derived for the interaction of an intense relativistic electron beam with a cylindrical slow-wave structure of arbitrary corrugation depth. It is shown that near a resonance, the Pierce parameter can be expressed in terms of the vacuum dispersion function and the beam current. The dispersion relation is valid in both the low-current (Compton) regime and the high-current (Raman) regime. The dispersion characteristics of the interaction, such as the linear instability growth rate and bandwidth, are analyzed for both regimes

    A Pierce-type mode analysis is presented for a planar electron beam in a rippled planar waveguide. This analysis describes the gain of a traveling-wave tube consisting of that geometry. The dispersion relation is given by the determinant of a matrix based on the coupling of different free-space modes through the boundary conditions. For the case of high-frequency, low-power amplifiers, the dispersion relation reduces to a simple cubic expression for the Compton regime, leading to three roots analogous to the Pierce solution of a standard traveling-wave tube. The analysis shows that this type of traveling-wave tube is capable of very high gain at extremely high frequencies

    McCune, Robert C.; Forsmark, Joy H.; Upadhyay, Vinod; Battocchi, Dante

    Incorporation of magnesium alloys in self-pierce rivet (SPR) joints poses several unique challenges among which are the creation of spurious galvanic cells and aggravated corrosion of adjacent magnesium when coated steel rivets are employed. This work firstly reviews efforts on development of coatings to steel fasteners for the diminution of galvanic corrosion when used with magnesium alloys. Secondly, approaches, based on several electrochemical methods, for the measurement of the galvanic-limiting effect of a number of commercially-available coatings to hardened 10B37 steel self-piercing rivets inserted into alloy couples incorporating several grades of magnesium are reported. Electrochemical impedance spectroscopy (EIS), zero-resistance ammeter (ZRA), corrosion potential and potential-mapping visualization methods (e.g. scanning vibrating electrode technique — SVET) are illustrated for the several rivet coatings considered.

  20. The classical Pierce diode: Using particle simulations on linear and nonlinear behavior and final states

    International Nuclear Information System (INIS)

    Crystal, T.L.; Kuhn, S.; Birdsall, C.K.

    1984-01-01

    The classical Pierce diode is a simple 1-d system of two shorted metal plates, a cold beam of electrons injected from one side and a neutralizing background of rigid ions. While the plasma medium is technically stable, the finiteness of the Pierce system allows stable and unstable operation. It is usefully studied as an archetypical bounded plasma system, related e.g., to Q-machines, particle accelerators, thermionic converters. New particle simulations of the Pierce diode have successfully recovered many novel linear phenomena including the dominant linear eigenmodes (seen in the internal electrostatic fields), and the dominant and subdominant eigenfrequencies, (seen both in the internal electrostatics and in the external circuit current, J/sub ext/(t)). These simulation results conform very well to detailed predictions of a new linear analysis. The final (nonlinear) state recovered can show critical dependence on initial (linear perturbation) conditions, and can be made steady-state (d.c.) or periodic-oscillatory by simply changing the initial conditions by a factor of 10/sup -4/ or less. A third class of final state is also possible which has oscillations which seem to be nonperiodic

    Full Text Available A four-helix bundle is a well-characterized motif often used as a target for designed pharmaceutical therapeutics and nutritional supplements. Recently, we discovered a new structural complexity within this motif created by a disulphide bridge in the long-chain helical bundle cytokine leptin. When oxidized, leptin contains a disulphide bridge creating a covalent-loop through which part of the polypeptide chain is threaded (as seen in knotted proteins. We explored whether other proteins contain a similar intriguing knot-like structure as in leptin and discovered 11 structurally homologous proteins in the PDB. We call this new helical family class the Pierced Lasso Bundle (PLB and the knot-like threaded structural motif a Pierced Lasso (PL. In the current study, we use structure-based simulation to investigate the threading/folding mechanisms for all the PLBs along with three unthreaded homologs as the covalent loop (or lasso in leptin is important in folding dynamics and activity. We find that the presence of a small covalent loop leads to a mechanism where structural elements slipknot to thread through the covalent loop. Larger loops use a piercing mechanism where the free terminal plugs through the covalent loop. Remarkably, the position of the loop as well as its size influences the native state dynamics, which can impact receptor binding and biological activity. This previously unrecognized complexity of knot-like proteins within the helical bundle family comprises a completely new class within the knot family, and the hidden complexity we unraveled in the PLBs is expected to be found in other protein structures outside the four-helix bundles. The insights gained here provide critical new elements for future investigation of this emerging class of proteins, where function and the energetic landscape can be controlled by hidden topology, and should be take into account in ab initio predictions of newly identified protein targets.

    Objective: To evaluate the relation between the morphology of the obstructive interface of the inferior vena cava (IVC)and the method of choice for taking the 'pierce membrane'. Methods: Interventional therapy was performed in 155 patients with obstruction of inferior vena cave during 2003-2005. The types of proximal part and distal end of obstruction were classified on the base of inferior vane cavography and divid[d into two groups accordingly. The principle of taking 'pierce membrane' whether as accending or descending route was decided by the morphology of the obstructive interface. The complication rates of taking 'pierce membrane' were compared between the two groups including one of 2003-2005 and another of 1990 -1997 as the control. Results: 155 cases were classified to 7 types according to morphology of inferior vena cava obstruction of the distal interface, the type of membrane with hole (32 cases), the dome type (50 cases), the taper type (17 cases), the horizontal type (13 cases), the inclination type (10 cases), the irregular type (19 eases)and the type of obstruction with communicating branches (14 cases). The morphologies of the proximal part of the obstruction were mainly divided into the type of membrane with hole, dome type, taper type and horizontal type. All the cases were successfully taken 'pierce membrane', without complication of pericardial effusion and abdominal bleeding. In control group of 150 Budd-Chiari syndrome cases with obstruction of inferior vena cava, the complications of taking 'pierce membrane' included mis puncture into pericardium (16 cases) and abdominal hemorrhage because of rupturing the inferior vena cava in 2 cases. Comparing the two groups, there was statistical significance with severe complications. Conclusions: 'Pierce membrane' interventional technique for the obstruction of inferior vena eava by coinciding the morphology of the obstructive interface with suitable piercing direction can not only raise successful

    The fastidious phytopathogenic bacterium, Xylella fastidiosa, poses a substantial threat to many economically important crops, causing devastating diseases including Pierce's Disease of grapevine. Grapevines (Vitis vinifera L.) planted in an area under Pierce's Disease pressure often display differences in disease severity and symptom expression, with apparently healthy vines growing alongside the dying ones, despite the fact that all the vines are genetic clones of one another. Under the hypothesis that endophytic microbes might be responsible for this non-genetic resistance to X. fastidiosa, endophytic fungi were isolated from vineyard cvs. 'Chardonnay' and 'Cabernet Sauvignon' grown under high Pierce's Disease pressure. A Cochliobolus sp. isolated from a Cabernet Sauvignon grapevine inhibited the growth of X. fastidiosa in vitro. Bioassay-guided isolation of an organic extract of Cochliobolus sp. yielded the natural product radicinin as the major active compound. Radicinin also inhibited proteases isolated from the culture supernatant of X. fastidiosa. In order to assess structure-activity relationships, three semi-synthetic derivatives of radicinin were prepared and tested for activity against X. fastidiosa in vitro. Assay results of these derivatives are consistent with enzyme inactivation by conjugate addition to carbon-10 of radicinin, as proposed previously. Copyright © 2015 Elsevier Ltd.

    Determination and analysis of neutron flux measurements on radial piercing beam port have been done as completion experimental data document and progressing on utilization of the Kartini research reactor purposes. The analysis and determination of the neutron flux have been carried out by using Au foils detector neutron activation analysis method which put on the radius of cross section (19 cm) and a long of radial piercing beam port (310 cm) Based on the calculation, distribution of the thermal neutron flux is around (8.3 ± 0.9) x 10 5 ncm -2 s -1 to (6.8 ± 0.5) x 10 7 ncm -2 s -1 and fast neutron is (5.0 ± 0.2) x 10 5 ncm -2 s -1 to (1.43 ± 0.6) x 10 7 ncm -2 s -1 . Analyzing by means of curve fitting method could be concluded that the neutron flux distribution on radial piercing beam port has profiled as a polynomial curve. (author)

  13. Underwater piercing of a tunnel

    1984-11-01

    Norwegian consultants and contractors have been confronted with the task of blasting a final penetrating passage that will open the way for the water in a reservoir to flow through the hydropower turbines. Norway has almost certainly led in this area because of its special topographical and geological conditions. The glacial activities have created a number of natural and very deep lakes forming cheap reservoirs. Piercings at depths up to about 100 m have been performed. Problems tend to increase with depth, but unsuccessful penetration can occur at any depth. Secondary effects to consider include the danger of slides when the water level is lowered, wave erosion along the lowered new shoreline, erosion at all streams and rivers flowing into the lake and groundwater erosion in the newly exposed dry shoreline. Methods of penetration can be roughly divided into two categories: penetration against the open tunnel shaft (open system); and penetration against the closed tunnel shaft (closed system). 6 figures.

    Watson, Fraser T.; Beck, Christian; Penn, Matthew J.; Tritschler, Alexandra; Pillet, Valentín Martinez; Livingston, William C.

    2015-11-01

    In this article we describe a recent effort to cross-calibrate data from an infrared detector at the McMath-Pierce Solar Telescope and the Facility InfraRed Spectropolarimeter (FIRS) at the Dunn Solar Telescope. A synoptic observation program at the McMath-Pierce has measured umbral magnetic field strengths since 1998, and this data set has recently been compared with umbral magnetic field observations from SOHO/MDI and SDO/HMI. To further improve on the data from McMath-Pierce, we compared the data with measurements taken at the Dunn Solar Telescope with far greater spectral resolution than has been possible with space instrumentation. To minimise potential disruption to the study, concurrent umbral measurements were made so that the relationship between the two datasets can be most accurately characterised. We find that there is a strong agreement between the umbral magnetic field strengths recorded by each instrument, and we reduced the FIRS data in two different ways to successfully test this correlation further.

  18. MANAGING NEWLY ESTABLISHED PESTS: Cooperative efforts contained spread of Pierce's disease and found genetic resistance

    Directory of Open Access Journals (Sweden)

    George Bruening

    2014-10-01

    Full Text Available An outbreak of Pierce's disease of grapevine in the Temecula Valley in the late 1990s was one in a decades-long series of sporadic appearances of this infection in California. However, the new outbreak was qualitatively different because of the rapidity with which it spread in the vineyard and its appearance almost simultaneously at distant locations. The causative agent of Pierce's disease is the bacterium Xylella fastidiosa, and the distinct characteristics of the Temecula Valley outbreak were traced to the establishment of a new insect vector in California, the glassy-winged sharpshooter. Intensive and collaborative efforts among government agencies, industry and research institutions over 15 years have successfully contained the disease, and given scientists time to discover promising long-term potential solutions through genetic resistance.

  1. Control of Pierce's Disease by Phage.

    Directory of Open Access Journals (Sweden)

    Mayukh Das

    Full Text Available Pierce's Disease (PD of grapevines, caused by Xylella fastidiosa subsp. fastidiosa (Xf, is a limiting factor in the cultivation of grapevines in the US. There are presently no effective control methods to prevent or treat PD. The therapeutic and prophylactic efficacy of a phage cocktail composed of four virulent (lytic phages was evaluated for control of PD. Xf levels in grapevines were significantly reduced in therapeutically or prophylactically treated grapevines. PD symptoms ceased to progress one week post-therapeutic treatment and symptoms were not observed in prophylactically treated grapevines. Cocktail phage levels increased in grapevines in the presence of the host. No in planta phage-resistant Xf isolates were obtained. Moreover, Xf mutants selected for phage resistance in vitro did not cause PD symptoms. Our results indicate that phages have great potential for biocontrol of PD and other economically important diseases caused by Xylella.

    An IGBT modulator has been developed to drive a 120 kV, 23 A Pierce electron gun. The modulator is capable of producing pulses up to 10 μs in width at repetition rates up to 10Hz with no active reset. The pulse rise time on the electron gun will be approximately 2 μs and the remaining 8 μs of flattop is tuned to have a ripple of less than 1 percent rms. The modulator technology was developed from a previous 50 kV prototype. The modulator consists of six boards, each with one EUPEC IGBT that drives a single common step-up transformer wound on METGLAS 2605SC cores. The six transformer cores share a common bi-filar output secondary winding. The modulator uses a fiber optic trigger system and has a high voltage cable output with an epoxy receptacle on the oil end and a ceramic receptacle on the vacuum end. The 120 kV electron gun was manufactured by MDS Co. and will be used to generate sheet electron beams from the standard pencil beam produced by the Pierce electron gun.

    To add three further dimensions of evidence for the care of women with genital piercings (GPs). Following a literature review, a cross-sectional study replicated previous work, using a web-based survey. This triad of evidence provides (a) descriptive quantitative data (N = 240) about women with GPs, (b) qualitative data about women with GPs, as well as (c) clinical observations from 60 healthcare providers (HCPs) who have cared for women with GPs. Three important findings about women with GPs were validated: (a) GPs were deliberate actions, sought for personal and sexual expression; (b) women with GPs treat piercings as a normal, meaningful part of their lives which produce sexual enhancement and expression; and (c) they continue to seek information about GP care from nonhealth providers. New data indicate that they have experienced depression (47%), abuse (physical 18%; emotional, 27%; sexual, 14%), and forced sexual activity (35%) in their lives. Several unsubstantiated assumptions about women with GPs are challenged with these data. GPs should not delay important health care. Health-protective, as well as health promotion, behaviors are important to reduce risks. Nurse practitioners (NPs) can become effective and resourceful advocates in three specific areas of care: (a) responsiveness to women with GPs, (b) collaborative decision making for the removal of jewelry, and (c) promotion of applicable patient education.

  8. Piercing the sovereign ceiling: Issues in oil and gas project financing

    International Nuclear Information System (INIS)

    Coleman, T.S.

    1998-01-01

    In the oil and gas sector, corporations and governments face huge capital spending requirements in order to transform large resource discoveries into producing, cash-generating assets. A significant portion of this funding is expected to be done on a project finance basis, where bank lenders or bond investors take a secured position in financing a discrete project, with the expectation of being paid back by the cash flows from that project after completion. This trend is increasing demand for crediting rating services to provide credit ratings for these project financings. A key challenge is to analyze and rate credit-worthy projects in countries that have relatively low foreign currency sovereign ceilings due to economic, political, and financial risks. In most cases, the credit ratings for projects financed in currencies outside the host country are capped at the country''s foreign currency ceiling. However, in a few instances, mainly in the oil and gas sector, Moody''s has pierced the foreign currency ceiling or rated certain projects above the sovereign ratings of the countries where they are domiciled. The purpose of this article is to briefly explain some of the qualitative factors and considerations that have allowed Moody''s to pierce the ceiling in the oil and gas sector, with a focus on two recent and noteworthy projects: Ras Laffan Liquefied Natural Gas in Qatar and Petrozuata in Venezuela

    - An increasing number of patients wear nail polish, artificial nails or have piercings.- There is uncertainty about the perioperative management of these items, especially when located outside the surgical area.- In the majority of hospitals, patients are urged to remove these items preoperatively, under the assumption that they might cause problems.- Frequently, however, these items cannot be removed straightforwardly.- Nail polish and artificial nails only very rarely cause perioperative problems and therefore do not need to be removed pre-operatively.- The same applies to most piercings, except when located in or near the respiratory tract, if they have sharp endings or if they might cause problems as a result of the perioperative positioning of the patient.- Providing adequate information to the patient, knowledge about removal of these items and documentation of agreed arrangements are all important.- A national guideline concerning perioperative policy is urgently required.

    The conclusion of J. Cameron and W. D. Pierce that rewards do not pose a threat to intrinsic motivation (1994) is a misrepresentation of the literature based on a flawed meta-analysis. Their analysis is more an attempt to defend behaviorist turf rather than meaningful consideration of relevant data and issues. (Author/SLD)

    1985-01-01

    In this work the design and construction of a simple form of Pierce Gun are discussed. As the vacuum system used in the experiment was frequently exposed to open air, a solenoid filamentary-cathode was used. Hence, an effective magnetic field has been induced as the filament was heated, whereupon the electrons altered their paths. We, therefore investigated the change in beam intensity as influenced by the focusing electrode material, anode position, and extraction hole width. The focusing electrode effect was examined by comparing the measured emission current density with the corresponding calculated value. The studies showed that electrons follow a saddle-like shape in the gun inter-space. It was modified by the stainless steel focusing electrode

    Seed treatments can directly protect cotton from early season piercing-sucking insect Aphis gossypii Glover but hardly provide long-term protection against Apolygus lucorum (Meyer-Dür). Therefore, the efficacy of clothianidin seed treatments combined with spot applications of clothianidin granules at the bud stage of cotton was evaluated to control piercing-sucking pests during the entire cotton growing season. Clothianidin seed treatments (at the rate of 4 g ai/kg seed) combined with a clothianidin granular treatment (even at low rate of 0.9 kg ai/ha) at the bud stage can effectively suppress A. gossypii and A. lucorum infestations throughout the seedling and blooming stages after planting and can improve cotton yield. The spot application of clothianidin granules also reduced the population densities of Bemisia tabaci (Gennadius). The dynamic changes of clothianidin residues demonstrated that the control efficacy of clothianidin against A. gossypii and A. lucorum might be related to the residues of this neonicotinoid in cotton leaves. This pest management practice provided long-term protection against cotton piercing-sucking pests for the entire growing season of cotton plants and could supplement the short-term control efficiency of clothianidin used as a seed treatment.

    The influences of the beam-plasma boundary and of weak nonlinearities on the Pierce instability are investigated. It is shown that the finite width of the beam has negligible influence on both the stability of the system and growth rate. In the nonlinear regime the wavelength decreases and enhancement of the wave potential close to the beam inlet boundary is observed. The relationship between this effect and the formation of double layers is discussed. (Auth.)

  20. Signal amplification and Pierce's instability in convergent particle beams

    Gnavi, G.; Gratton, F.T.

    1988-01-01

    Relativistic electron beams flowing between cylindrical and spherical electrodes (or solid angles sections of electrodes with these geometries) are studied. The beams are focused through the axis in the cylindrical case or through the center when spherical electrodes are considered. It is assumed that the external electrode is part of a device which accelerates the particles, the inner electrode is passive and removes the beams from the system. Electrons move by inertia in the interelectrode space, neutralized by an ion background. Properties of radial, small amplitude, perturbations are analyzed theoretically. Previous analyses of counterstreaming beams indicated that convergence modifies considerably the oscillations spectrum. Here, results on the amplification of signals when a beam is modulated at the external electrode are reported. Then, conditions for the instability of a beam when it flows through grounded electrodes (Pierce's instability of only one beam) are examined

    Full Text Available Investigou-se a atuação de uma rocha com espodumênio como fundente em massas cerâmicas, analisando-se sua reatividade com outras matérias-primas, como quartzo e caulim. Primeiramente, caracterizou-se petrograficamente o pegmatito de onde se extrai esse fundente. Posteriormente avaliou-se o comportamento de moabilidade, fundência e deformação piroplástica da rocha com espodumênio. Analisou-se então sua influência nas propriedades tecnológicas finais das peças, principalmente em relação à temperatura de queima, às fases e à microestrutura. Comparou-se a gresificação com outros fundentes comerciais como a albita e o feldspato. O espodumênio mostrou maior capacidade de reduzir a temperatura de gresificação das peças que os fundentes tradicionais, promovendo a densificação por fluxo viscoso.A spodumene rock was used as a flux in ceramic bodies, analyzing its reactivity to other raw materials such as quartz and kaolin. The petrology properties of the pegmatite (parent rock from which the flux is extracted was characterized. The grindability, fluxing strength and pyroplastic deformation of the spodumene rock were investigated. The influence on technological properties of the final pieces, mainly in relation to the firing temperature, phases formation and microstructure were also further analyzed. The firing behavior to other commercial flux such as albite and feldspar were then compared. The spodumene rock was considered an effective flux, capable of reducing the firing temperatures of the tested bodies by viscous flow.

    2010-01-01

    Laser assisted self-piercing riveting (LSPR) is a new solid state process that enables low ductility materials to be mechanically joined without cracking. A simple but effective thermal analysis of LSPR is presented that enabled both the absorption of the laser radiation and heat transfer between plies to be determined. The approach was applied to experimental data for LSPR joining of AZ31B-H24 magnesium alloy sheets. It is shown that by using this analytical approach, the temperature at the onset of joining could be estimated and related to observations of joint quality. It was found that crack-free joints were produced at strip temperatures above 200 o C at the time of rivet insertion.

    The discovery of a large number of supermassive black holes (SMBH) at redshifts z > 6, when the Universe was only 900 million years old, raises the question of how such massive compact objects could form in a cosmologically short time interval. Each of the standard scenarios proposed, involving rapid accretion of seed black holes or black hole mergers, faces severe theoretical difficulties in explaining the short-time formation of supermassive objects. In this work we propose an alternative scenario for the formation of SMBH in the early Universe, in which energy transfer from superconducting cosmic strings piercing small seed black holes is the main physical process leading to rapid mass increase. As a toy model, the accretion rate of a seed black hole pierced by two antipodal strings carrying constant current is considered. Using an effective action approach, which phenomenologically incorporates a large class of superconducting string models, we estimate the minimum current required to form SMBH with masses of order M = 2 x 10{sup 9} M {sub CircleDot} by z = 7.085. This corresponds to the mass of the central black hole powering the quasar ULAS J112001.48+064124.3 and is taken as a test case scenario for early-epoch SMBH formation. For GUT scale strings, the required fractional increase in the string energy density, due to the presence of the current, is of order 10{sup -7}, so that their existence remains consistent with current observational bounds on the string tension. In addition, we consider an ''exotic'' scenario, in which an SMBH is generated when a small seed black hole is pierced by a higher-dimensional F-string, predicted by string theory. We find that both topological defect strings and fundamental strings are able to carry currents large enough to generate early-epoch SMBH via our proposed mechanism.

    Full Text Available Background: Body piercing is a cultural practice or tradition in various civilizations dating back to antiquity. In recent years, body piercing has become increasingly fashionable for purely esthetic reasons and the practice cuts across all sectors of society. The emergence of oral tattoos especially among young adults is of concern to dental and medical professionals because of the risks and complications for oral, dental and general health. Intraoral piercings involve the tongue, while perioral piercings involve the lips, the cheeks and to a lesser extent the uvula and the frenum. Education is a primary method to intercept or prevent risky behavior of oral piercing and dental professionals have a major role in providing guidance about perioral /oral modification.

    The measurement of an electron beam profile has been performed using electron beam monitor based on method of phosphorescent materials. The main components of the electron beam monitor consists of a fluorescent sensor using a used Tv tube, CCTV camera to record images on a Tv screen, video adapter as interface between CCTV and laptop, and the laptop as a viewer and data processing. Two Pierce-type electron sources diode and triode was measured the shape of electron beam profile in real time. Results of the experiments showed that the triode electron source of Pierce type gave the shape of electron beam profiles better than that of the diode electron source .The anode voltage is not so influential on the beam profile shape. The focused voltage in the triode electron source is so influence to the shape of the electron beam profile, but above 5 kV no great effect. It can be concluded that the electron beam monitor can provide real time observations and drawings shape of the electron beam profile displayed on the used Tv tube glass screen which is the real picture of the shape of the electron beam profile. Triode electron source produces a better electron beam profile than that of the diode electron source. (author)

    Full Text Available O uso de marcas corporais tem se tornado cada vez mais frequente, sobretudo entre adolescentes. Através de abordagem qualitativa, este estudo pretende avaliar se o uso de piercings e tatuagens afeta o cuidado prestado por auxiliares de enfermagem a adolescentes internados e identificar influências na formação dos significados atribuídos às marcas. Foram entrevistados auxiliares que trabalham em enfermaria específica para o atendimento de adolescentes. Após análise das entrevistas, foram formuladas categorias para melhor apreensão do sentido atribuído pelos auxiliares ao uso de marcas. Algumas categorias foram recorrentes, destacando-se a associação das marcas a: comportamentos de desvio; apelo erótico e consumismo; gesto de coragem; riscos de adoecimento e doença mental. Religião e valores familiares predominaram sobre a formação profissional em relação aos significados atribuídos ao objeto de estudo. Conclui-se que a visão negativa em relação às marcas relaciona-se diretamente ao cuidado. A quantidade de marcas, a localização, o tipo, a idade do adolescente e o caráter definitivo/transitório interferem na interpretação dos profissionais. Contudo, marcas corporais são ferramentas semiológicas importantes, devendo ser incluídas no roteiro de avaliação dos adolescentes.Nowadays, body art is widespread, especially among adolescents.

    Studies on sensitization to metals in the general population are scarce. To determine the prevalence of sensitization to metals in the general population, and factors associated with nickel sensitization. In 5 European countries (The Netherlands, Germany, Italy, Portugal and Sweden), a random sample (N = 3119) from the general population (aged 18-74 years) was patch tested and interviewed by use of a questionnaire on exposure to metals, piercing, and jewellery. Overall, the age-standardized prevalences of sensitization to nickel, cobalt and chromium were, respectively, 14.5%, 2.1%, and 0.8%. The highest prevalence of nickel sensitization was seen in Portugal (18.5%) and the lowest (8.3%) in Sweden. The prevalence of cobalt sensitization varied between 3.8% (The Netherlands) and 0.9% (Italy), and the prevalence of chromium sensitization varied between 1.3% (Portugal) and 0.2% (Sweden). Significant associations were observed between nickel allergy and female sex (odds ratio [OR] 5.19; 95% confidence interval [95%CI]: 3.99-6.74), past piercing use (OR 3.86; 95%CI: 2.85-5.24), and currently having ≥3 piercings (OR 5.58; 95%CI: 4.02-7.76). The prevalence of sensitization to metals in the European general population was high, mostly because of nickel. The lowest prevalence of contact allergy to nickel and chromium observed in Sweden supports the effectiveness of long-standing regulation. © 2018 The Authors.

    Neutron diffraction was used to describe the residual stress distributions in self-piercing riveted (SPR) joints. The sheet material displayed a compressive residual stress near the joint, and the stress gradually became tensile in the sheet material far away from the joint. The stress in the rivet leg was lower in the thick joint of the softer steel sheet than in the thin joint of the harder steel sheet. This lower magnitude was attributed to the lower force gradient during the rivet flaring...

    2017-01-01

    Full Text Available Due to its relevance in ocean engineering, the subject of the flow field generated by water waves around a vertical circular cylinder piercing the free surface has recently started to be considered by several research groups. In particular, we studied this problem starting from the velocity-potential framework, then the implementation of the numerical solution of the Euler equations in their velocity-pressure formulation, and finally the performance of the integration of the Navier-Stokes equations in primitive variables. We also developed and applied methods of extraction of the flow coherent structures and most energetic modes. In this work, we present some new results of our research directed, in particular, toward the clarification of the main nonintuitive character of the phenomenon of interaction between a wave and a surface-piercing cylinder, namely, the fact that the wave exerts its maximum force and exhibits its maximum run-up on the cylindrical obstacle at different instants. The understanding of this phenomenon becomes of crucial importance in the perspective of governing the entity of the wave run-up on the obstacle by means of wave-flow-control techniques.

En una mirada a la historia de las prácticas corporales, vemos que el concepto de técnica varía de acuerdo al período estudiado, así como los trabajos que sobre lo corporal realizan distintas culturas. Nuestra exploración tomará como referencia: la antigua Grecia, con su concepto de techné; la Edad Media y la Modernidad como escenario clave en el que se funda la Educación Física. Nos proponemos, en este trabajo, rescatar la noción de técnica corporal como concepto amplio, presente en toda actividad humana, valorándola como construcción cultural tradicional en lo que se refiere a los usos del cuerpo. Esta visión es un intento por no reducir el concepto de técnica al de una tecnología del cuerpo, solidaria con un tecnicismo dominante desde fines del siglo XIX, muy presente en la educación. The purpose of this paper is based on an exploration into the notion of body technique at different times in the occidental history, regarding it within a broader concept in relation to technique in general, and therefore related to the world of work, science and education.

Our exploration will refer to ancient Greece, with its concept of techné; the Middle Ages and the Modern Period as a crucial stage where Physical Education was born.

  2. Pierced Lasso Proteins

    Science.gov (United States)

    Jennings, Patricia

    Entanglement and knots are naturally occurring, where, in the microscopic world, knots in DNA and homopolymers are well characterized. The most complex knots are observed in proteins which are harder to investigate, as proteins are heteropolymers composed of a combination of 20 different amino acids with different individual biophysical properties. As new-knotted topologies and new proteins containing knots continue to be discovered and characterized, the investigation of knots in proteins has gained intense interest. Thus far, the principle focus has been on the evolutionary origin of tying a knot, with questions of how a protein chain `self-ties' into a knot, what the mechanism(s) are that contribute to threading, and the biological relevance and functional implication of a knotted topology in vivo gaining the most insight. Efforts to study the fully untied and unfolded chain indicate that the knot is highly stable, remaining intact in the unfolded state orders of magnitude longer than first anticipated. The persistence of ``stable'' knots in the unfolded state, together with the challenge of defining an unfolded and untied chain from an unfolded and knotted chain, complicates the study of fully untied protein in vitro. Our discovery of a new class of knotted proteins, the Pierced Lassos (PL) loop topology, simplifies the knotting approach. While PLs are not easily recognizable by the naked eye, they have now been identified in many proteins in the PDB through the use of computation tools. PL topologies are diverse proteins found in all kingdoms of life, performing a large variety of biological responses such as cell signaling, immune responses, transporters and inhibitors (http://lassoprot.cent.uw.edu.pl/). Many of these PL topologies are secreted proteins, extracellular proteins, as well as, redox sensors, enzymes and metal and co-factor binding proteins; all of which provide a favorable environment for the formation of the disulphide bridge.

    The stability of electron flow passage through the diode with a neutralized space charge has been investigated on the basis of the first-order approximation for hydrodynamic and Maxwell equations. Classification of solutions to the equations was developed in accordance with the magnitude and nature (potential or eddy) of the electric field arising at the diode cathode. The stability regions for these states have been found. It is shown that the presence of external electromagnetic action makes the stability region narrower than that predicted by Pierce.

  5. A 3D, fully Eulerian, VOF-based solver to study the interaction between two fluids and moving rigid bodies using the fictitious domain method

    Pathak, Ashish; Raessi, Mehdi

    2016-04-01

    We present a three-dimensional (3D) and fully Eulerian approach to capturing the interaction between two fluids and moving rigid structures by using the fictitious domain and volume-of-fluid (VOF) methods. The solid bodies can have arbitrarily complex geometry and can pierce the fluid-fluid interface, forming contact lines. The three-phase interfaces are resolved and reconstructed by using a VOF-based methodology. Then, a consistent scheme is employed for transporting mass and momentum, allowing for simulations of three-phase flows of large density ratios. The Eulerian approach significantly simplifies numerical resolution of the kinematics of rigid bodies of complex geometry and with six degrees of freedom. The fluid-structure interaction (FSI) is computed using the fictitious domain method. The methodology was developed in a message passing interface (MPI) parallel framework accelerated with graphics processing units (GPUs). The computationally intensive solution of the pressure Poisson equation is ported to GPUs, while the remaining calculations are performed on CPUs. The performance and accuracy of the methodology are assessed using an array of test cases, focusing individually on the flow solver and the FSI in surface-piercing configurations. Finally, an application of the proposed methodology in simulations of the ocean wave energy converters is presented.

    Full Text Available The goal of this article is to discuss the phenomenon of the ethos of affective sexual experience of transvestites at the interface with modeling one’s body. A changing reality, the body in contemporary society is a kind of merchandise - a product entitled to minor repairs and predetermined duration. It was also observed the construction of identities and subjectivities based on artifacts established under or on the skin: piercings, tattoos, scarification, silicone, hormones, body building, crossdressing – which have turned the body into a means of affirmation of the self. The use of silicone, hormones and plastic surgery to achieve the ideal body modeling by transvestites has become commonplace among this population leading to an issue of public health due to the injuries, deformities and even death that often result from such practices. The phenomenological method was chosen to analyze, understand and interpret the speeches of three transvestites belonging to social classes C and D; aged between 20 and 30 years on the meanings they attribute to the process of modeling their body and the affective sexual practices arising from such transformation. The results obtained from the analysis of the three interviews led to three categories: "The dream of beauty and a perfect body"; "Pain and the recovery process as a rite of passage"; and "Change in behavior / personality resulting from the applications". In their search of the perfect body they dare and cross the ethical boundaries of aesthetics and health. They subvert the sense of self-care to meet the market logic.

    This final report summarizes the design and performance of the VUW-8028 Pierce-Wiggler electron beam systems, which can be used to power high frequency gyro-BWO's. The operator's manual for this gyro-BWO beamstick is included as appendix A. Researchers at Lawrence Livermore National Laboratory (LLNL) are developing a gyro-BWO with a center frequency of 250 GHz, 6% bandwidth, and 10 kV peak output power. The gyro-BWO will be used to drive a free electron laser amplifier at LLNL. The electron beam requirements of the gyro-BWO application are: Small beam size, .100 inch at 2500 gauss axial magnetic field; a large fraction of the electron energy in rotational velocity; ability to vary the electrons' axial velocity easily, for electronic tuning; and low velocity spread i.e. little variation in the axial velocities of the electrons in the interaction region. 1 ref., 13 figs

    A comprehensive study, integrating gravity, magnetic and seismic reflection data, has been used to resolve the complex Triassic salt body geometry and evolution in central Tunisia. Regional seismic lines across the study area show a detachment level in the Upper Triassic evaporites, associated with chaotic seismic facies below the Souinia, Majoura, and Mezzouna structures. The Jurassic and Lower Cretaceous seismic horizons display pinching-outs and onlapping around these structures. A stack-velocity section confirms the existence of a high-velocity body beneath the Souinia Mountain. Regional gravity and magnetic profiles in this area were elaborated from ETAP (the Tunisian Firm of Petroleum Activities) measure stations. These profiles were plotted following the same layout from the west (Souinia) to the east (Mezzouna), across the Majoura and Kharrouba mountains. They highlight associated gravity and magnetic negative anomalies. These gravity and magnetic data coupled to the reflection seismic data demonstrate that, in the Souinia, Majoura, and El Hafey zones, the Triassic salt reaches a salt pillow and a salt-dome stage, without piercing the cover. These stages are expressed by moderately low gravity anomalies. On the other hand, in the Mezzouna area (part of the North-South Axis), the Triassic salt had pierced its cover during the Upper Cretaceous and the Tertiary, reaching a more advanced stage as a salt diapir and salt wall. These stages express important low gravity and magnetic anomalies. These results confirm the model of Tanfous et al. (2005) of halokinetic movements by fault intrusions inducing, from the west to the east, structures at different stages of salt pillow, salt dome, and salt diapir.

    This descriptive and exploratory study from a quantitative approach aimed to characterize workers who were victims of work accidents related to human body fluids exposure and to evaluate the accident victim care protocol. The population consisted of 48 workers who were victims of work accidents involving exposure to human body fluids, from July 2000 to June 2001. Data were collected through a form and interviews. Results showed that nursing workers presented higher accident risk levels and that 87.50% involved piercing and cutting material, such as needles and butterflies (70%). As to the accident-related situation/activity, the workers indicated that 25% were due to an "inadequate act during the procedure"; 19.64% mentioned that "it happened" and 29.17% answered that they did not have any suggestion. This study provided important tools to review and elaborate strategies to prevent accidents involving exposure to human body fluids.

    2018-04-01

    Full Text Available The extended Bonora damage model was used to investigate joinability of materials in self-piercing riveting process. This updated model formulation accounts for void nucleation and growth process and shear-controlled damage which is critical for shear fracture sensitive materials. Potential joint configurations with dissimilar materials have been investigated computationally. In particular the possible combination of DP600 steel, which is widely used in the automotive industry, with AL2024-T351, which is known to show shear fracture sensitivity, and oxygen-free pure copper, which is known to fail by void nucleation and growth, have been investigated. Preliminary numerical simulation results indicate that the damage modelling is capable to discriminate potential criticalities occurring in the SPR joining process opening the possibility for process parameters optimization and screening of candidate materials for optimum joint

    Extreme rituals (body-piercing, fire-walking, etc.) are anecdotally associated with altered states of consciousness—subjective alterations of ordinary mental functioning (Ward, 1984)—but empirical evidence of altered states using both direct and indirect measures during extreme rituals in naturalistic settings is limited. Participants in the “Dance of Souls”, a 3.5-hour event during which participants received temporary piercings with hooks or weights attached to the piercings and danced to music provided by drummers, responded to measures of two altered states of consciousness. Participants also completed measures of positive and negative affect, salivary cortisol (a hormone associated with stress), self-reported stress, sexual arousal, and intimacy. Both pierced participants (pierced dancers) and non-pierced participants (piercers, piercing assistants, observers, drummers, and event leaders) showed evidence of altered states aligned with transient hypofrontality (Dietrich, 2003; measured with a Stroop test) and flow (Csikszentmihalyi, 1990; Csikszentmihalyi & Csikszentmihalyi, 1990; measured with the Flow State Scale). Both pierced and non-pierced participants also reported decreases in negative affect and psychological stress and increases in intimacy from before to after the ritual. Pierced and non-pierced participants showed different physiological reactions, however, with pierced participants showing increases in cortisol and non-pierced participants showing decreases from before to during the ritual. Overall, the ritual appeared to induce different physiological effects but similar psychological effects in focal ritual participants (i.e., pierced dancers) and in participants adopting other roles.

    Based on Foucault’s concept of the body as the surface of inscription of history, and on the work of Judith Butler, this article questions the way that binary and normative conceptions of gender operate in the constitution of a field of intelligibility for subjects and their bodies. We analyse the film XXY (2007 that tells the story of Alex, an intersexual adolescent. We use the main character's story to see how gender norms act to shape bodies and limit their pleasures. We argue that subjects and bodies that do not correspond to the normative ideal are seen as “abject bodies”, following Butler’s definition. The argument is that gender norms operate on all bodies: the normal and the abject.

  2. Penetrators for delivering Scientific equipment to minor bodies by flying-pass missions.

    Bagrov, Alexander; Martynov, Maxim; Pichkhadze, Konstantin M.; Dolgopolov, Vladimir; Sysoev, Valentin

    Many space missions are planned to have close encounters with Solar system minor bodies as a pass-fly. Short time of such close encounters were effectively used for photographing of these bodies, i.e. for distant investigations only because of large velocities of the encounter. We propose to use high-velocity penetrators to provide contact investigations of the minor bodies in situ. These devices were designed by Lavochkin Association for lunar missions. They were designed for long lived scientific equipment to be placed under surface up to depth 2...3 m. Penetrators could survive under 500 g shock, so the contact velocity was from 90 to 250 m/s, so each of them had booster engine to decelerate orbital velocity. As flying-pass velocity near minor body can be more then 10 km/s, penetrators would hit target at speed above 1 km/s and successfully bear 1500 g. To do so we propose to fulfill whole internal space inside penetrator with distilled water and froze it to temperature - 80°C or lower. At this temperature water ice is as hard as steel, so penetrator will plunge into target like armour-piercing shell. After landing protective ice will be evaporated (particularly due to heating from collision) and all sensitive mechanics will be set free.

    A synthesis technique for the preliminary design of convergent Pierce electron guns is introduced briefly which has a series of advantages over the traditional methods. A thermal cathode electron gun used in the accelerator for radiation sterilization with the synthesis method is redesigned, and the validity of this method is proved. Based on the preliminary design parameters given by the synthesis method, a simulating calculation program, EGUN, was used in the numerical figure design of the focusing electrode and the anode. The final results can meet the engineering requirement as the current being 1A, the normalized emittance being less than 4 mm·mrad, and the final current density showing uniformity

    An arrangement for and method of inserting a glass microelectrode having a tip in the micron range into body tissue is presented. The arrangement includes a microelectrode. The top of the microelectrode is attached to the diaphragm center of a first speaker. The microelectrode tip is brought into contact with the tissue by controlling a micromanipulator. Thereafter, an audio signal is applied to the speaker to cause the microelectrode to vibrate and thereby pierce the tissue surface without breaking the microelectrode tip. Thereafter, the tip is inserted into the tissue to the desired depth by operating the micromanipulator with the microelectrode in a vibratory or non-vibratory state.

    A reduction in material usage of cold forged components while maintaining the functional requirements can be achieved using hollow or tubular preforms. These preforms are used to meet lightweight requirements and to decrease production costs of cold formed components. To increase production efficiency in common multi-stage cold forming processes, manufacturing of hollow preforms by combining the processes backward cup extrusion and piercing was established and will be discussed in this paper. Corresponding investigations and experimental studies are reported in this article. The objectives of the experimental investigations have been the detection of significant process parameters, determination of process limits for the combined processes and validation of the numerical investigations. In addition, the general influence concerning surface quality and diameter tolerance of hollow performs are discussed in this paper. The final goal is to summarize a guideline for industrial application, moreover, to transfer the knowledge to industry, as regards what are required part geometries to reduce the number of forming stages as well as tool cost.

  6. Simulation of the Groundwater-Flow System in Pierce, Polk, and St. Croix Counties, Wisconsin

    Groundwater is the sole source of residential water supply in Pierce, Polk, and St. Croix Counties, Wisconsin. A regional three-dimensional groundwater-flow model and three associated demonstration inset models were developed to simulate the groundwater-flow systems in the three-county area. The models were developed by the U.S. Geological Survey in cooperation with the three county governments. The objectives of the regional model of Pierce, Polk, and St. Croix Counties were to improve understanding of the groundwaterflow system and to develop a tool suitable for evaluating the effects of potential water-management programs. The regional groundwater-flow model described in this report simulates the major hydrogeologic features of the modeled area, including bedrock and surficial aquifers, groundwater/surface-water interactions, and groundwater withdrawals from high-capacity wells. Results from the regional model indicate that about 82 percent of groundwater in the three counties is from recharge within the counties; 15 percent is from surface-water sources, consisting primarily of recirculated groundwater seepage in areas with abrupt surface-water-level changes, such as near waterfalls, dams, and the downgradient side of reservoirs and lakes; and 4 percent is from inflow across the county boundaries. Groundwater flow out of the counties is to streams (85 percent), outflow across county boundaries (14 percent), and pumping wells (1 percent). These results demonstrate that the primary source of groundwater withdrawn by pumping wells is water that recharges within the counties and would otherwise discharge to local streams and lakes. Under current conditions, the St. Croix and Mississippi Rivers are groundwater discharge locations (gaining reaches) and appear to function as 'fully penetrating' hydraulic boundaries such that groundwater does not cross between Wisconsin and Minnesota beneath them. Being hydraulic boundaries, however, they can change in response to

    We describe magnetic foreign body injuries among children and obtain national estimates of magnetic foreign body injury incidence over time. We searched the National Electronic Injury Surveillance System for cases of magnetic foreign bodies in children younger than 21 years in the United States, from 2002 to 2011. Cases were analyzed by location: alimentary or respiratory tract, nasal cavity, ear canal, or genital area. We identified 893 cases of magnetic foreign bodies, corresponding to 22,581 magnetic foreign body cases during a 10-year period (95% confidence interval [CI] 17,694 to 27,469). Most magnetic foreign bodies were ingested (74%) or intranasal (21%). Mean age was 5.2 years for ingested magnetic foreign bodies and 10.1 years for nasal magnetic foreign bodies (difference 4.9; 95% CI 4.1 to 5.6), suggesting different circumstances of injury. The incidence of pediatric magnet ingestions increased from 2002 to 2003 from 0.57 cases per 100,000 children per year (95% CI 0.22 to 0.92) to a peak in 2010 to 2011 of 3.06 cases per 100,000 children per year (95% CI 2.16 to 3.96). Most ingested magnetic foreign bodies (73%) and multiple magnet ingestions (91%) occurred in 2007 or later. Patients were admitted in 15.7% of multiple magnet ingestions versus 2.3% of single magnet ingestions (difference 13.4%; 95% CI 2.8% to 24.0%). Magnet-related injuries are an increasing public health problem for young children, as well for older children who may use magnets for play or to imitate piercings. Education and improved magnet safety standards may decrease the risk small magnets pose to children. Copyright © 2013 American College of Emergency Physicians. Published by Mosby, Inc.

    Full Text Available O estupro durante muito tempo foi considerado como ato de poucos e degenerados maníacos sexuais. Mas, em meados do século XX, o entendimento sobre esse crime foi sendo modificado, deixando a margem social da experiência cotidiana para ser compreendido como uma relação de força e poder de homens sobre mulheres. Relação esta legitimada socialmente como parte integrante da formação das subjetividades masculinas. Procuramos, a partir da análise de processos criminais de estupro instaurados na comarca de Curitiba, Estado do Paraná, ao longo da década de 1950, analisar os discursos produzidos sobre a violência sexual e sua vinculação aos padrões de masculinidade e feminilidade naquele contexto histórico. Objetivamos problematizar a construção das masculinidades de homens que estavam no limiar entre a necessidade de demonstração de virilidade e dominação, representada na posse sexual do corpo feminino, e a anormalidade da violência sexual. Em que medida esses homens dialogavam com a masculinidade hegemônica deste contexto específico? Como jogavam discursivamente para produzir uma zona de sombra que lhes permitisse não serem julgados anormais pelos seus pares? Nesse contexto em que as mulheres estavam cada vez mais envolvidas com o mundo público, o estupro, mais do que relação sexual forçada, passava a funcionar como um dispositivo de modelação de condutas sexuais e sociais que operava na construção do medo da presença em espaços de vulnerabilidade feminina

    Amro, Elias; Kouadri-Henni, Afia

    2018-05-01

    Restrictions in pollutant emissions dictated at the European Commission level in the past few years have urged mass production car manufacturers to engage rapidly several strategies in order to reduce significantly the energy consumption of their vehicles. One of the most relevant taken action is light-weighting of body in white (BIW) structures, concretely visible with the increased introduction of polymer-based composite materials reinforced by carbon/glass fibers. However, the design and manufacturing of such "hybrid" structures is limiting the use of conventional assembly techniques like resistance spot welding (RSW) which are not transferable as they are for polymer-metal joining. This research aims at developing a joining technique that would eventually enable the assembly of a sheet molding compound (SMC) polyester thermoset-made component on a structure composed of several high strength steel grades. The state of the art of polymer-metal joining techniques highlighted the few ones potentially able to respond to the industrial challenge, which are: structural bonding, self-piercing riveting (SPR), direct laser joining and friction spot welding (FSpW). In this study, the promising SPR technique is investigated. Modelling of SPR process in the case of polymer-metal joining was performed through the building of a 2D axisymmetric FE model using the commercial code Abaqus CAE 6.10-1. Details of the numerical approach are presented with a particular attention to the composite sheet for which Mori-Tanaka's homogenization method is used in order to estimate overall mechanical properties. Large deformations induced by the riveting process are enabled with the use of a mixed finite element formulation ALE (arbitrary Lagrangian-Eulerian). FE model predictions are compared with experimental data followed by a discussion.

  14. SPR Characteristics Curve and Distribution of Residual Stress in Self-Piercing Riveted Joints of Steel Sheets

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Neutron diffraction was used to describe the residual stress distributions in self-piercing riveted (SPR joints. The sheet material displayed a compressive residual stress near the joint, and the stress gradually became tensile in the sheet material far away from the joint. The stress in the rivet leg was lower in the thick joint of the softer steel sheet than in the thin joint of the harder steel sheet. This lower magnitude was attributed to the lower force gradient during the rivet flaring stage of the SPR process curve. This study shows how the residual stress results may be related to the physical occurrences that happened during joining, using the characteristics curve. The study also shows that neutron diffraction technique enabled a crack in the rivet tip to be detected which was not apparent from a cross-section.

Por un lado, considera que el cuerpo humano ha sido descorporeizado y proyectado en el no lugar del espacio telemático, enfrentado así a las tendencias de rematerialización del cuerpo, como el arte carnal y el body art, y, por otra, parte considera que incluso en esta esfera ciberespacial el cuerpo de Internet se ve como una prolongación del arte carnal, según los trabajos de Orlan y Tomic. La construcción del género y el trabajo artístico de las mujeres en la red es otro de los objetivos que este texto pone de manifiesto como vinculación de mujeres y nuevas tecnologías en el contexto artístico del net.art.This text deals with the role that the representation of the human body acquired in net.art. On the one hand, considers that the human body has been disembodied and projected in the nowhere of telematic space, thus faced to the rematerialization trends of the body, as the carnal art and body art, and by the other hand considers that even in this cyberspace area the Internet´s body is seen as an extension of carnal art, depending on the work of Orlan and Tomic. The construction of gender and women's artwork in the network is another objective that this text shows as linking between women and new technologies in the artistic context of net.art.

    The external starshade is a method for the direct detection and spectral characterization of terrestrial planets around other stars, a key goal identified in ASTRO2010. Tests of this approach have been and continue to be conducted in the lab and in the field (Samuele et al., 2010, Glassman et al., 2014) using non-collimated light sources with a spherical wavefront. We extend the current approach to performing night-time observations of astronomical objects using small-scale (approximately 1/300th) starshades and the McMath-Pierce Solar Telescope at Kitt Peak National Observatory. We placed a starshade directly in the path of the beam from an astronomical object in front of the main heliostat. Using only flat mirrors, we then directed the light through the observatory path and reflected it off the West heliostat to an external telescope located approximately 270m away, for an effective baseline of 420m.This configuration allowed us to make measurements of flat wavefront sources with a Fresnel number close to those expected in proposed full-scale space configurations. We present the results of our engineering runs conducted in 2015.

  17. Belly button piercings: a saving grace? A patent urachus presenting in a 17-year-old girl.

    We report the case of a 17-year-old girl who presented to the accident and emergency department with dysuria and foul smelling, bloody discharge from her umbilicus. The definitive diagnosis was that of a patent urachus, which is a fistulous communication between the bladder and the umbilicus, usually diagnosed in early infancy. The incidence of a patent urachus is approximately 1 in 70,000 in the general population. It is highly likely that removal of a recent belly button piercing resulted in the acute presentation by completing the fistulous tract to the skin. This case is of clinical relevance as the diagnosis was missed 18 months prior with a milder presentation. The recommended treatment option is surgical excision due to the potential risk of malignant change, with urachal adenocarcinoma accounting for 0.3% of all bladder cancers. 2014 BMJ Publishing Group Ltd.

  18. Sealing of transmitted-heat lines at wall piercings; Abdichtung von Fernwaermeleitungen in Mauerdurchfuehrungen

    Flexible sealing systems are necessary to provide permanent protection of transmitted-heat pipe wall penetrations against the ingress of water. Unlike the rigid sealing methods in widespread use, flexible sealing systems are capable of absorbing thermally induced pipe movements and thus of preventing leaks around such piercings. The following article provides an introduction to the subject and offers practical suggestions for the ideal design of transmitted-heat pipe wall penetrations. Sealing system variants with a range of degrees of flexibility are discussed, in addition to measures which need to be taken into account as early as the installation of the pipe itself. Prime attention is devoted not to methods already practised, but to recent, potentially marketable developments. (orig.) [Deutsch] Um Mauerdurchfuehrungen von Fernwaermeleitungen dauerhaft gegen das Eindringen von Wasser zu schuetzen, sind flexible Abdichtsysteme notwendig. Im Gegensatz zu den verbreiteten starren Abdichtungsmethoden koennen flexible Systeme die thermisch bedingten Rohrbewegungen aufnehmen und damit Undichtigkeiten im Bereich der Durchfuehrungen verhindern. Der folgende Beitrag fuehrt in die Thematik ein und gibt praktische Hinweise, wie eine Mauerdurchfuehrung von Fernwaermeleitungen idealerweise gestaltet werden sollte. Neben Massnahmen, die bereits bei der Rohrverlegung zu beachten sind, werden Abdichtvarianten mit unterschiedlichem Flexibilitaetsgrad skizziert. Schwerpunkt der Untersuchung liegt hier nicht nur auf bereits bekannten Verfahren sondern auch auf marktfaehigen Neuentwicklungen. (orig.)

  19. Is the HP-UHP Hong'an-Dabie-Sulu orogen a piercing point for offset on the Tan-Lu fault?

    2013-02-01

    The Tan-Lu fault is a major strike-slip fault in eastern China that appears to offset the high-grade rocks of the Hong'an-Dabie-Sulu orogen left-laterally ˜540 km. We evaluate models for the collision between the South and North China blocks, published radiometric dates recording HP-UHP metamorphism and exhumation in the Hong'an-Dabie and Sulu terranes, and the timing of sinistral motion on the Tan-Lu fault to evaluate whether UHP rocks provide a piercing point for offset on the Tan-Lu fault. UHP metamorphism in Hong'an-Dabie was concurrent with Sulu based on U-Pb dating of coesite-bearing domains of zircon at 244 ± 5-226 ± 2 Ma for Hong'an-Dabie and 243 ± 4-225 ± 2 Ma for Sulu. Retrograde metamorphism began c. 220 Ma for both Hong'an-Dabie and Sulu, but retrograde zircon growth ended c. 214 Ma in Hong'an-Dabie and continued until c. 202 Ma in Sulu based on U-Pb dating of zircon domains external to coesite-bearing domains. Structures in Sulu are rotated 25° counter-clockwise from, but are broadly similar to, Hong'an-Dabie suggesting the two areas have a common Triassic orogenic history that pre-dates motion on the Tan-Lu fault, and that is consistent with paleomagnetic studies. We constructed a pre-Cretaceous restoration of the Hong'an-Dabie-Sulu belt that moves the Sulu terrane south, aligning the suture and the eclogite-facies isograd, and rotates Sulu c. 25° clockwise to re-align structures with Hong'an-Dabie. Our restoration is supported by published data and shows that the Hong'an-Dabie-Sulu orogen is a piercing point for post-collisional offset on the Tan-Lu fault and that these regions shared a common subduction-exhumation history. The Tan-Lu fault did not play a significant role in the Hong'an-Dabie-Sulu collision and likely developed later, in the Early Cretaceous.

  20. Multiple bodies in the spirituality of the gay porn star McCree: reflections on corporeality and subjectivity

    Full Text Available Body modification practices have lately gained growing visibility in contemporary Western cultures. It is more like a trend or fashion ranging from, on the on hand, decorative tattoos and piercing, to branding, implants and surgery on the other. In most forms body modification occurs without any obvious religious, spiritual or ideological marks attached, but some forms involve discourses that explicitly address such aspirations. However, despite the fluidity and diversity of practices, it can be claimed that body modification represents specific or distinct ways of working with the body that differ from other forms of contemporary Western body cultures. Further, it needs be considered as part of the broader body culture. Hence it draws our attention to the role of corporeality in contemporary Western culture. Body modification could be regarded as a reaction to the nature of contemporary society, a way of compensating the lack of corporeal engagement in the world. Its former association with different subcultures might underpin this oppositional position. On the other hand, some scholars regard body-modification as nothing but part of the contemporary free floating carnival of signs, as mere mainstream supermarket signifiers, emptied of meaning and deprived of any external references. In this article emphasis is put on forms of body modification that more explicitly connote religion. One example of body modification is explored from an empirical perspective: the story about the spirituality of the gay porn star Logan McCree. This is a personal narrative about spirituality in which tattooing plays a central role. Still, despite being personal it is also part of McCree’s public image. With the help of both literature and the examples on body modification the place of corporeality in the story of McCree is explored. The aim is to shed some light on corporeality and in particular in relation to subjectivity.

    Full Text Available Various light materials including aluminum alloys and magnesium alloys are being used to reduce the weight of vehicle structures. Joining of dissimilar materials is always a challenging task to construct a solid structure. Self-piercing rivet (SPR joint is one of various joining methods for dissimilar materials. Front shock tower structures were constructed with magnesium alloy (AM60 joined to aluminum alloy (Al6082 by SPR joints. To evaluate the durability performance of the SPR joints in the structures, fatigue tests of the front shock tower structures were conducted with constant amplitude loadings. Furthermore, this study investigated fatigue life prediction method of SPR joints and compared the fatigue life prediction results with that of experimental results. For fatigue life prediction of the SPR joints in the front shock tower structures, lap-shear and cross-tension specimens of SPR joint were constructed and tested to characterize the fatigue properties of the SPR joint. Then, the SPR joint was represented with area contact method (ACM in finite element (FE models. The load-life curves of the lap-shear and cross-tension specimens were converted to a structural stress-life (S-N curve of the SPR joints. The S-N curve was used to predict fatigue life of SPR joints in the front shock tower structures. The test results and the prediction results were well correlated.

    Pierce's disease (PD) is a destructive bacterial disease of grapes caused by Xylella fastidiosa which is xylem-confined. The tolerance level to this disease varies among Vitis species. Our research was aimed at identifying unique xylem sap proteins present in PD-tolerant Vitis species. The results showed wide variation in the xylem sap protein composition, where a set of polypeptides with pI between 4.5 and 4.7 and M(r) of 31 kDa were present in abundant amount in muscadine (Vitis rotundifolia, PD-tolerant), in reduced levels in Florida hybrid bunch (Vitis spp., PD-tolerant) and absent in bunch grapes (Vitis vinifera, PD-susceptible). Liquid chromatography/mass spectrometry/mass spectrometry analysis of these proteins revealed their similarity to beta-1, 3-glucanase, peroxidase, and a subunit of oxygen-evolving enhancer protein 1, which are known to play role in defense and oxygen generation. In addition, the amount of free amino acids and soluble sugars was found to be significantly lower in xylem sap of muscadine genotypes compared to V. vinifera genotypes, indicating that the higher nutritional value of bunch grape sap may be more suitable for Xylella growth. These data suggest that the presence of these unique proteins in xylem sap is vital for PD tolerance in muscadine and Florida hybrid bunch grapes.

    BodyText" style="margin: 0cm 0cm 0pt; line-height: normal;">Este texto visa apresentar uma leitura crítica acerca da prática de planejamento. Não é um esboço histórico, mas tão-somente uma interpretação do planejamento e como este está inserido na lógica de reprodução da sociedade capitalista. Argumenta para tanto que a prática de planejamento é realizada pela instituição estatal. Esta é um produto genuíno das sociedades de classes. O próprio estado tem como base social uma classe específica: a burocracia. Esta defende, dentro dos quadros da sociedade capitalista, os interesses gerais da burguesia, por mais que possa dentro de dadas circunstâncias sociais específicas opor-se a frações da burguesia, mas nunca aos interesses gerais de classe da burguesia. Defendemos que o poder é uma relação de dominação. Como tal, o planejamento é desta maneira uma manifestação da dominação de classe através da regulação do estado. A instituição estatal é desta forma responsável tanto por regularizar a prática do planejamento, quanto em muitos casos executar os planos ela própria. Assim, defende-se neste texto a necessidade de se superar as relações sociais que engendram o planejamento viabilizado pelo estado. Suprime-se assim o próprio planejamento.

Entonces eran los descuentos que se empezaban a extender en las farmacias, francesas sobre todo, y que amenazaban el prestigio profesional de todo el colectivo.

  2. Anisotropic structure of the Inner Core and its uncertainty from transdimensional body-wave tomography

    Science.gov (United States)

    Burdick, S.; Waszek, L.; Lekic, V.

    2017-12-01

    Studies of body waves and normal modes have revealed strong quasi-hemispheric variations in seismic velocity, anisotropy and attenuation in the inner core. A rigorous mapping of the hemispheric boundaries and smaller scale heterogeneity within the hemispheres is crucial for distinguishing between hypotheses about inner core formation and evolution. However, the relatively sparse and heterogeneous distribution of paths piercing the inner core creates difficulties in constraining the boundaries and sub-hemispheric variations with body wave tomography. Damped tomographic inversions tend to smooth out strong structural gradients and risk carrying the imprint of sparse path coverage, while under-parametrized models can miss pertinent small-scale variations. For these reasons, we apply a probabilistic and transdimensional (THB) tomography method on core-sensitive differential P-wave traveltimes. The THB approach is well-suited to the problem of inner core tomography since 1) it remains parsimonious by allowing the parametrization to be determined the requirements of the data and 2) it preserves sharp boundaries in seismic properties, allowing it to capture both short-wavelength structure and the strong hemispheric dichotomy. Furthermore, the approach yields estimates of uncertainty in isotropic and anisotropic velocity, hemispheric boundary geometry, anisotropy axis and the tradeoffs between these properties. We quantify the effects of mantle heterogeneity with inner core structure and place constraints on inner core dynamics and minerology.

    Full Text Available El artículo examina el concepto de leyenda como intangible territorial en diversas escalas, desde la local a la regional o nacional, y su relación con la construcción de mitos étnicos y la emergencia de tradiciones translocales. Para ello, se revisan la metodología de los estudios corográficos y las nociones de ecotipo y de paisaje cultural, así como la etnografía de los territorios simbólicos a la luz de conceptos como el clásico «témenos» y modernos como el «mytho-moteur» (Abadal, 1958. Se aplican estudios de casos que evidencian cómo es el Imaginario, en interacción con factores geohistóricos del lugar, el que a menudo acota y perimetrea un territorio a través de cauces como la fabulación legendaria y los ritos paralitúgicos, como procesiones o peregrinaciones. La conclusión es que las leyendas y los arquetipos de origen étnico y genealógico reescriben tradiciones que crean identidades y se pueden proyectar en ámbitos diferentes de la vida política o recreativa, con perfiles igualmente diferentes.

    1995-01-01

    Full Text Available Joseph Beuys, nacido en Cléveris (Renania del Norte-Westfalia en 1921 y faliecido en Dusseldorf en 1986, posee una obra madura casi desde un primer momento. Superficialmente podríamos verla como el canto a sí mismo de un gran narcisista, donde sus experiencias y su persona son los grandes protagonistas. En una lectura más profunda, estos hechos personales no son más que el medio para ir más allá del yo y dar lugar a una creación plástica de trascendencia social. Tras la 2- Guerra Mundial, en la que lucha como piloto de la Luftwaffe, estudia en la Academia de Bellas Artes de Dusseldorf. Será a partir de los años 60 cuando encontremos al auténtico Beuys, escultor objetual e instalador, el creador de la plástica social, y desde sus contactos con Fluxus en 1962, el Beuys accionista. En los 70, se nos presenta el artista más claramente politizado. La educación, la incidencia social del arte, el arte como «tercera vía o vía alternativa» entre socialismo y capitalismo, la ecología serán sus materiales de trabajo.

    Full Text Available "Espécimes" inodoros, secos e quase eternos, produzidos a partir de cadáveres humanos por uma técnica chamada plastinação, estão sendo amplamente usados como modelos de anatomia em exposições e faculdades de medicina. Milhões de leigos já viram corpos dissecados em uma das espetaculares exposições de anatomia pelo mundo e um novo mercado on-line de "espécimes" humanos plastinados está crescendo. Mais do que transformações físico-químicas, a plastinação, associada a outros procedimentos, também realiza uma transformação simbólica que reduz o corpo-pessoa a corpo-objeto para neutralizar a poluição e o tabu associados aos cadáveres humanos. Contudo, as circunstâncias obscuras sobre como esses corpos foram doados, comprados ou mesmo roubados traz o status de pessoa de volta aos corpos, assim como chama a nossa atenção para novas questões éticas e morais.Odorless, dry and almost everlasting "specimens", produced from human corpses by a technique called plastination, are being used as anatomy models in exhibitions and medical schools. Millions of lay people have already seen dissected corpses in one of the spectacular human anatomy exhibitions around the world and a new on-line market for plastinated human "specimens" is growing. More than chemical and physical transformations, plastination, associated with other procedures, also makes a symbolic transformation that reduces the person-body into object-body in order to neutralize the pollution and the taboo associated with human corpses. But unclear circumstances about these bodies and questions as to whether they have been donated, sold, or even stolen bring status as "people" back to the corpses and draws our attention to new ethical and moral questions.

    Full Text Available ResumoEste artigo considera como o estudo da cultura e da aprendizagem pode ser de particular relevância para o campo da antropologia sociocultural em geral. O termo mais importante na expressão “cultura & aprendizagem” talvez seja o logograma “&” – ou seja, coloca-se a questão sobre o que conecta cultura e aprendizagem, perguntando-se como esses termos estão relacionados. Como devemos compreender cultura e aprendizagem como instâncias produtoras delas próprias, e uma da outra, na prática? Recalibrando em termos relacionais, podemos dizer que não é possível abordar a “aprendizagem” ou “cultura e aprendizagem” sem o seu emaranhamento na vida político-econômica, nas lutas e disputas históricas, em suas coerências e incoerências, e na produção relacional e histórica da vida cotidiana. Através das lentes da teoria da prática social, os estudos etnográficos sobre aprendizagem na prática oferecem diferentes entendimentos sobre como certa vida e certas disputas e incoerências são produzidas.

    2010-03-01

    Full Text Available En el año 2005 Martínez-Vargas formuló un sistema de cokrigeage puro heterotópico para estimar una función aleatoria regionalizada (RF Z*(x definida como la combinación lineal de n RF's univariadas Zi(x, cuyos coeficientes 1i(x son indicatrices de un set disyuntivo de categorías i. Aparentemente este modelo se contradice pues asume que las covarianzas cruzadas existen en un mismo punto, a pesar de su carácter puramente heterotópico. Para evadir dicha contradicción se redefinió el set de RF Zi(x como una única RF Z(x,i, siendo los puntos (x,i y (x,j no coincidentes si i y j no son iguales. La heterotopía fue simplemente considerada como una omisión de la RF Z(x,. en los datos y en los puntos a estimar, no impuesta por el modelo; entonces el resultado es simplemente un caso particular del cokrigeage clásico. Con esta notación se reescribió el sistema de cokrigeage clásico como el sistema de krigeage de la RF univariada Z(x,i, asumiendo que esta posee un drift definido como m(x,i,j, donde los miembros fl(x,i,j de m(x,i,j pueden ser linealmente dependientes o independientes. Bajo esta notación el sistema de krigeage se reduce a un sistema univariado, la existencia de más de una variable o la presencia de heterotropía no impone la necesidad de manipulaciones extras para definir el sistema de ecuaciones de krigeage, incrementándose la eficiencia computacional.

  6. Traditional and New Enhancing Human Cybernetic and Nanotechnological Body Modification Technologies: A Comparative Study of Roman Catholic and Transhumanist Ethical Approaches

    Science.gov (United States)

    Caligiuri, Michael J.

    Advances in cybernetic and nanotechnological body modifications currently allow for enhancements to human physical and mental function which exceed human species-based norms. This thesis examines body modification and human enhancement from two perspectives---Roman Catholicism and Transhumanism--- in order to contribute to bioethical deliberations regarding enhancement technologies. Roman Catholicism has a longstanding tradition of bioethical discourse, informing the healthcare directives of Roman Catholic institutions. Transhumanism is more recent movement that endorses body modifications and human enhancements as a means of individual betterment and social evolution. The thesis first considers definitions of human enhancement and levels of normalcy in connection to cybernetic and nanotechnological bionic implants, and outlines a series of criteria to assess a technology's potential bioethical acceptability: implantability, permanency, power, and public interaction. The thesis then describes Roman Catholicism's response to non-enhancing decorative body modifications (cosmetic surgeries, common decorative modifications such as tattoos and piercings, and uncommon modifications such as scarifications and brandings) in order to establish a basis for possible Roman Catholic responses to enhancing cybernetic and nanotechnological modifications. This is followed by an analysis from a Roman Catholic perspective of the major social issues brought forward by enhancement technologies: commodification, eugenics, vulnerability, and distributive justice. Turning to Transhumanism, the thesis describes the origins and philosophy of the movement, and then discusses the bioethical principles it advances with regard to human enhancement. The thesis concludes by locating points of convergence between Transhumanism and Roman Catholicism that could be the basis of more widely accepted ethical guidelines regarding modification technologies.

    Michele Cukiert

    2002-01-01

    Full Text Available O artigo trata da problemática do eu e do corpo em Lacan, articulados a partir de sua releitura do texto freudiano. Aponta como o autor, interrogando-se sobre a gênese do eu, retoma conceitos freudianos fundamentais tais como ego, identificação e narcisismo. Dessa forma, por meio da elaboração do registro do Imaginário e do esquema conceitual proposto pelo estádio do espelho, afirma a importância da imagem do corpo próprio na formação do eu, marcando também o desconhecimento e a alienação como constitutivos do eu. Indica como as noções de eu e de corpo sofrem transformações correlativas às retificações que Lacan opera em sua teoria, articulando-se também ao Simbólico e ao Real. Assim, no interior do campo psicanalítico delimitado pelo autor, o corpo pode ser pensado e estudado a partir de sua concepção dos três registros fundamentais: do ponto de vista do Imaginário, o corpo como imagem, do ponto de vista do Simbólico, o corpo marcado pelo significante, e do ponto de vista do Real, o corpo como sinônimo de gozo. Retoma a novidade freudiana acerca da corporeidade, afirmando que o corpo em Psicanálise não se reduz ao campo da Biologia. Finalmente, discute de que forma a teoria lacaniana possibilita repensar essa problemática a partir da linguagem.This article covers the issue of the moi and the body in Lacan, based on his re-reading of Freudian texts. It indicates how the author, questioning the constitution of the moi, goes back to Freudian fundamental concepts such as ego, identification and narcissism. In this way, through the elaboration of the Imaginary level and the proposed conceptual scheme of the mirror stage, it assures the importance of the image of the body in the formation of the moi, making also the unknown and the alienation as constituents of the moi. It indicates how the notions of the moi and the body suffer correlative transformations by the rectifications in Lacan's theory, as do the Symbolic

  9. Intermittent Fermi-Pasta-Ulam Dynamics at Equilibrium

    Science.gov (United States)

    Campbell, David; Danieli, Carlo; Flach, Sergej

    The equilibrium value of an observable defines a manifold in the phase space of an ergodic and equipartitioned many-body syste. A typical trajectory pierces that manifold infinitely often as time goes to infinity. We use these piercings to measure both the relaxation time of the lowest frequency eigenmode of the Fermi-Pasta-Ulam chain, as well as the fluctuations of the subsequent dynamics in equilibrium. We show that previously obtained scaling laws for equipartition times are modified at low energy density due to an unexpected slowing down of the relaxation. The dynamics in equilibrium is characterized by a power-law distribution of excursion times far off equilibrium, with diverging variance. The long excursions arise from sticky dynamics close to regular orbits in the phase space. Our method is generalizable to large classes of many-body systems. The authors acknowledge financial support from IBS (Project Code IBS-R024-D1).

    Full Text Available Leyendo el artículo titulado “Los medicamentos baratos” de la revista La Farmacia Española, publicada en Madrid el jueves 21 de diciembre de 1893, uno se pregunta cómo puede ser que se reconozca la situación como si fuera de ahora mismo, cómo puede ser que estemos igual que hace más de cien años. Entonces eran los descuentos que se empezaban a extender en las farmacias, francesas sobre todo, y que amenazaban el prestigio profesional de todo el colectivo. Con frases como éstas se define la situación que se presentaba en aquel momento: “…el desprestigio de que vaya por unos cuantos desnaturalizándose el ejercicio de la farmacia en tal forma que se convierta en un comercio impuro y de la peor estofa; pero conviene mucho combatir con mano firme la tendencia a la baratería, tanto más cuanto que no puede dudarse que significa un rebajamiento a todas luces nocivo y que supone una desorganización que nos llevaría en breve a la más completa ruina, y lo que creo aún más grave, a la desmoralización y el desorden, que no se compadecen en modo alguno con lo que en realidad es hoy y ha sido siempre el ejercicio de una profesión genuinamente científica como lo es la de la farmacia”. La propuesta que se hacía para controlar la situación era “la limitación de farmacias, con vigilancia estrecha del Estado y tarifa uniforme oficial”, así como “hace falta mucha inteligencia y mucha unión, hace falta que nadie permanezca indiferente, que todos y cada uno pongan de su parte lo que puedan”. Nuestra profesión mezcla una doble vertiente sanitaria y comercial que no siempre es fácil mantener equilibrada y, por lo que se ve, esto ha ocurrido así desde siempre. El problema que existe hoy en día es la mercantilización de la farmacia, un desplazamiento de establecimiento sanitario hacia una simple empresa.

    This research work investigates body education in urban spaces of sociability in the cit of Belo Horizonte, from 1897 to 1905. Legislation appears as an important source, as it allows for the analysis of projects envisaged by the State, establishing rules for the use of the urban space. It presents texts that encode desirable values and regulate social behavior. Legislative acts clarify the intentions of the State in terms of regulating the relationship society should have with the space it occupies, and they show that growing urbanization can categorize spaces and determine social practices which are authorized or hidden, thus creating a new sensitivity to the body.

    This work presents optimal linear quadratic regulator (LQR) based on genetic algorithm (GA) to solve the two degrees of freedom (2 DoF) motion control problem in head seas for wave piercing catamarans (WPC). The proposed LQR based GA control strategy is to select optimal weighting matrices (Q and R). The seakeeping performance of WPC based on proposed algorithm is challenged because of multi-input multi-output (MIMO) system of uncertain coefficient problems. Besides the kinematical constraint problems of WPC, the external conditions must be considered, like the sea disturbance and the actuators (a T-foil and two flaps) control. Moreover, this paper describes the MATLAB and LabVIEW software plats to simulate the reduction effects of WPC. Finally, the real-time (RT) NI CompactRIO embedded controller is selected to test the effectiveness of the actuators based on proposed techniques. In conclusion, simulation and experimental results prove the correctness of the proposed algorithm. The percentage of heave and pitch reductions are more than 18% in different high speeds and bad sea conditions. And the results also verify the feasibility of NI CompactRIO embedded controller.

É na maneira como o cinema articula e aproxima as imagens e os sons que verificamos sua transformação em discurso. Criam-se novos sentidos, uma nova lógica onde os significados não são transparentes, nascida da associação de fragmentos. Justapõem-se duas realidades: a da vida propriamente dita e a do filme, a do discurso e, ainda dentro do filme, a justaposição de planos determinando novas leituras das Imagens. Partindo dos princípios da teoria da montagem cinematográfica de S. M. Eisenstein, faremos um rápido panorama de como o cinema, no decorrer de sua história, foi influenciado pelos conceitos desenvolvidos em sua teoria.

    We examined the apoptotic effect of a novel Probiotics Fermentation Technology (PFT) kefir grain product; PFT is a natural mixture composed primarily of Lactobacillus kefiri P-IF, a specific strain of L. kefiri with unique growth characteristics. The aim of this study was to examine the apoptotic effect of PFT on human multidrug-resistant (MDR) myeloid leukemia (HL60/AR) cells in vitro and explore the mechanistic approach underlying its effect. HL60/AR cells were cultured with PFT (0.6–5.0 mg/ml) for 3 days. The apoptotic effect of PFT was assessed through examination of percent apoptosis, caspase 3 activation, Bcl-2 expression levels and changes in mitochondrial membrane potential (MMP). PFT induced apoptosis in HL60/AR cells in a dose-dependent manner which was maximal at 67.5% for 5 mg/ml. Induction of apoptosis was associated with activation of caspase 3, decreased expression of Bcl-2 and decreased polarization of MMP. In addition, PFT showed a unique characteristic of piercing holes in HL60/AR cells, as indicated by AFM studies. This hole induction may be responsible for the apoptotic effect on cancer cells. These results suggest that PFT may act as a potential therapy for the treatment of MDR leukemia. PMID:24430613

Estas se caracterizan por imponer a los sujetos una constante modificación de conductas, pensamientos, actitudes etc., proceso que Deleuze denomina “modulación” y que se opone al “moldeado” disciplinario descripto por Foucaulty que no necesita del “encierro” para operar. La vigilancia se ejerce no sobre los cuerpossino sobre la “información” y el propio sujeto participa activamente en la misma. Sostenemos que esta fragilización de las de identificaciones producidas por estos modos de control, provocan sufrimientos, angustias y nuevos síntomas tanto en el cuerpo como en las subjetividades.

Our hypothesis is that this hybrid zone between art and science has been mobilizing important conceptions, such as memory, cognition, movement, habit, nature, and culture, among others, producing an important support for new epistemologies on the body.

    A Brazilian isolate of Hibiscus latent Fort Pierce virus (HLFPV-BR) was firstly found in a hibiscus plant in Limeira, SP, Brazil. RACE PCR was carried out to obtain the full-length sequences of HLFPV-BR which is 6453 nucleotides and has more than 99.15 % of complete genomic RNA nucleotide sequence identity with that of HLFPV Japanese isolate. The genomic structure of HLFPV-BR is similar to other tobamoviruses. It includes a 5' untranslated region (UTR), followed by open reading frames encoding for a 128-kDa protein and a 188-kDa readthrough protein, a 38-kDa movement protein, 18-kDa coat protein, and a 3' UTR. Interestingly, the unique feature of poly(A) tract is also found within its 3'-UTR. Furthermore, from the total RNA extracted from the local lesions of HLFPV-BR-infected Chenopodium quinoa leaves, a biologically active, full-length cDNA clone encompassing the genome of HLFPV-BR was amplified and placed adjacent to a T7 RNA polymerase promoter. The capped in vitro transcripts from the cloned cDNA were infectious when mechanically inoculated into C. quinoa and Nicotiana benthamiana plants. This is the first report of the presence of an isolate of HLFPV in Brazil and the successful synthesis of a biologically active HLFPV-BR full-length cDNA clone.

    2010-06-01

    Using a modified multilocus sequence typing (MLST) scheme for the bacterial plant pathogen Xylella fastidiosa based on the same seven housekeeping genes employed in a previously published MLST, we studied the genetic diversity of two subspecies, X. fastidiosa subsp. fastidiosa and X. fastidiosa subsp. sandyi, which cause Pierce's disease and oleander leaf scorch, respectively. Typing of 85 U.S. isolates (plus one from northern Mexico) of X. fastidiosa subsp. fastidiosa from 15 different plant hosts and 21 isolates of X. fastidiosa subsp. sandyi from 4 different hosts in California and Texas supported their subspecific status. Analysis using the MLST genes plus one cell-surface gene showed no significant genetic differentiation based on geography or host plant within either subspecies. Two cases of homologous recombination (with X. fastidiosa subsp. multiplex, the third U.S. subspecies) were detected in X. fastidiosa subsp. fastidiosa. Excluding recombination, MLST site polymorphism in X. fastidiosa subsp. fastidiosa (0.048%) and X. fastidiosa subsp. sandyi (0.000%) was substantially lower than in X. fastidiosa subsp. multiplex (0.240%), consistent with the hypothesis that X. fastidiosa subspp. fastidiosa and sandyi were introduced into the United States (probably just prior to 1880 and 1980, respectively). Using whole-genome analysis, we showed that MLST is more effective at genetic discrimination at the specific and subspecific level than other typing methods applied to X. fastidiosa. Moreover, MLST is the only technique effective in detecting recombination.

    Xylella fastidiosa is a xylem-limited bacterium in plant hosts and causes Pierce's disease (PD) of grapevines, which differ in susceptibility according to the Vitis species (spp.). In this work we compared X. fastidiosa biofilm formation and population dynamics when cultured in xylem saps from PD-susceptible and -resistant Vitis spp. under different conditions. Behaviors in a closed-culture system were compared to those in different sap-renewal cultures that would more closely mimic the physicochemical environment encountered in planta. Significant differences in biofilm formation and growth in saps from PD-susceptible and -resistant spp. were only observed using sap renewal culture. Compared to saps from susceptible V. vinifera, those from PD-resistant V. aestivalis supported lower titers of X. fastidiosa and less biofilm and V. champinii suppressed both growth and biofilm formation, behaviors which are correlated with disease susceptibility. Furthermore, in microfluidic chambers X. fastidiosa formed thick mature biofilm with three-dimensional (3-D) structures, such as pillars and mounds, in saps from all susceptible spp. In contrast, only small aggregates of various shapes were formed in saps from four out of five of the resistant spp.; sap from the resistant spp. V. mustangensis was an exception in that it also supported thick lawns of biofilm but not the above described 3-D structures typically seen in a mature biofilm from the susceptible saps.

In this work we compared X. fastidiosa biofilm formation and population dynamics when cultured in xylem saps from PD-susceptible and -resistant Vitis spp. under different conditions. Behaviors in a closed-culture system were compared to those in different sap-renewal cultures that would more closely mimic the physicochemical environment encountered in planta. Significant differences in biofilm formation and growth in saps from PD-susceptible and -resistant spp. were only observed using sap renewal culture.

    2009-01-01

    Full Text Available El trabajo se propone ofrecer una comprensión tanto de los orígenes como de los límites de la problematicidad de la interpretación jurídica -en particular, aunque no de modo único, de la interpretación constitucional-, focalizada en la estructura intencional del Derecho como discurso escrito y como práctica social. En cuanto discurso, el Derecho se concibe como un conjunto de "actos del habla"; en tanto práctica social, la comprensibilidad del Derecho se vincula a los fines o a las intenciones que se proponen sus participantes y que lo distinguen de otras prácticas sociales. Se concluye desde esta doble perspectiva que, lejos de ser un método entre otros, la interpretación teleológica es la estructura formal indisponible de toda interpretación jurídica. Sobre esta base se intenta mostrar que, aunque la proyección teleológica del Derecho opere como causal de la problematicidad de la interpretación jurídica, al mismo tiempo se constituye en el límite o marco para la dimensión creativa de la interpretación. A partir de aquí se defiende la tesis de que la problematicidad de la interpretación jurídica no es sinónimo de arbitrariedad en el Derecho constitucionalizado, al menos si se asumen dos postulados. Primero, que la abstracción del lenguaje jurídico es indeterminación, pero no vaguedad. Segundo, que los fines últimos del Derecho se ligan a una concepción de persona objetiva -metafísica, no política-.

    Full Text Available RESUMEN: Habitar las ciudades es un proceso en el que se encuentran anudadas cuestiones materiales y simbólicas. Este lazo debe ser atendido y puesto en valor en términos históricos y culturales ya que forma parte de nuestro aprendizaje como sujetos urbanos. En este sentido, tal como afirma Andreas Huyssen (2002: 191 "...la ciudad funciona como un tipo de prisma" que permite "enfocar" una multiplicidad de temáticas que no están solo ligadas al urbanismo o a la arquitectura, sino también a experiencias culturales y construcciones simbólicas que articulan el hecho concreto de vivir en las ciudades. Es así que, siguiendo a este autor, podemos afirmar que la ciudad es un texto que puede ser leído como un verdadero espacio de signos. Una casa, un barrio, un edificio, los espacios públicos, las calles y veredas, los monumentos son reservorios de un tiempo y una memoria que requieren de una multiplicidad de lecturas para transformarse en escenarios de aprendizajes integradores. Cuestionar a la ciudad como territorio de la educación integral así como reconocer las cuestiones centrales que se ponen a prueba cuando esto se postula como una política pública son los objetivos principales del presente artículo, para lo cual proponemos un recorrido a partir de considerar conceptos nodales como los de educación integral y pedagogía urbana.

It states the logic of complexity, the complex thought and the rational, open and complex systems, as a new paradigm. In the light of the organization concept proposed by Morin, complex adaptative systems are emphasized, as well as other terms such as order, disorder, incidental events and noises. The self-eco-organizer process, takes the human being thinking as starting point and as dynamizer of simple and complex processes in the construction of knowledge about reality. Some research studies such as those of Erdmann, Meirelles and Pradebon show some ways in which one can learn from the organizational reality of nursing, the exercise of complex thinking in uncertainty, in tenous limits, in heterogeneity, diversity and pluralism of phenomena in its aspect, interactions and associations. The inter subjectivity states a new concept of space and of temporality. The care system organization in nursing visualizes several dimensions of "caríng": to care for himself, to care for himself together with the other, to be looked after by the other, to feel and the process of personal care system, the body itself as the nucleus of care, the fact of belonging to the system of multiple caring relations and the care for nature getting integrated to other beings and other social, natural systems, and in thisway strengthen the feeling of ownership, in search of a better survival, vitality, life human quality.

The mass-dependent allometry should be applied during space flights as well as during fetal and newborn conditions of life, whereas the weight-dependence should prevail in earth-bound physiology. The above mentioned distinctions are relevant not only for the specific metabolic rates but also for numerous biological time functions, as for instance for the heart and respiratory rates of all mammals, whose allometric exponent is b = - 0.09 during fetal life, and b = - 0.25 in all adult specimens.El objetivo del presente trabajo fue la comparación de dos diferentes criterios de similitud, uno basado en la masa corporal (M como sistema teórico de referencia de acuerdo con el sistema MLT de la Física, en tanto que el otro utilizó el peso corporal (W con este mismo propósito. La alometría dependiente de la masa debería aplicarse durante los vuelos espaciales así como durante la vida fetal y la condición de recién nacido, en tanto que la dependencia del peso debe prevalecer en la fisiología terrestre. La distinción antes mencionada es relevante, no sólo para el metabolismo específico y también para numerosas funciones biológicas en relación con funciones de tiempo, como ser con las frecuencias cardiaca y respiratoria de todos los mamíferos cuyo exponente alométrico es b = - 0,09 durante la vida fetal, y b = - 0,25 en todos los especimenes adultos.

    Xylella fastidiosa (X. fastidiosa) infects a wide range of plant hosts and causes economically serious diseases, including Pierce's Disease (PD) of grapevines. X. fastidiosa biocontrol strain EB92-1 was isolated from elderberry and is infectious and persistent in grapevines but causes only very slight symptoms under ideal conditions. The draft genome of EB92-1 revealed that it appeared to be missing genes encoding 10 potential PD pathogenicity effectors found in Temecula1. Subsequent PCR and sequencing analyses confirmed that EB92-1 was missing the following predicted effectors found in Temecula1: two type II secreted enzymes, including a lipase (LipA; PD1703) and a serine protease (PD0956); two identical genes encoding proteins similar to Zonula occludens toxins (Zot; PD0915 and PD0928), and at least one relatively short, hemagglutinin-like protein (PD0986). Leaves of tobacco and citrus inoculated with cell-free, crude protein extracts of E. coli BL21(DE3) overexpressing PD1703 exhibited a hypersensitive response (HR) in less than 24 hours. When cloned into shuttle vector pBBR1MCS-5, PD1703 conferred strong secreted lipase activity to Xanthomonas citri, E. coli and X. fastidiosa EB92-1 in plate assays. EB92-1/PD1703 transformants also showed significantly increased disease symptoms on grapevines, characteristic of PD. Genes predicted to encode PD0928 (Zot) and a PD0986 (hemagglutinin) were also cloned into pBBR1MCS-5 and moved into EB92-1; both transformants also showed significantly increased symptoms on V. vinifera vines, characteristic of PD. Together, these results reveal that PD effectors include at least a lipase, two Zot-like toxins and a possibly redundant hemagglutinin, none of which are necessary for parasitic survival of X. fastidiosa populations in grapevines or elderberry.

    RNA interference (RNAi) is a powerful means to study functional genomics in insects. The delivery of dsRNA is a challenging step in the development of RNAi assay. Here, we describe a new delivery method to increase the effectiveness of RNAi in the Asian citrus psyllid Diaphorina citri. Bromophenol blue droplets were topically applied to fifth instar nymphs and adults on the ventral side of the thorax between the three pairs of legs. In addition to video recordings that showed sucking of the bromophenol blue by the stylets, dissected guts turned blue indicating that the uptake was through feeding. Thus, we called the method topical feeding. We targeted the abnormal wing disc gene (awd), also called nucleoside diphosphate kinase (NDPK), as a reporter gene to prove the uptake of dsRNA via this method of delivery. Our results showed that dsRNA-awd caused reduction of awd expression and nymph mortality. Survival and lifespan of adults emerged from treated nymphs and treated adults were affected. Silencing awd caused wing malformation in the adults emerged from treated nymphs. Topical feeding as a delivery of dsRNA is highly efficient for both nymphs and adults. The described method could be used to increase the efficiency of RNAi in D. citri and other sap piercing-sucking hemipterans. © 2017 Wiley Periodicals, Inc.

    Xylella fastidiosa causes Pierce's disease (PD) on grapevines, leading to significant economic losses in grape and wine production. To further our understanding of X. fastidiosa virulence on grapevines, we examined the PD1311 gene, which encodes a putative acyl-coenzyme A (acyl-CoA) synthetase, and is highly conserved across Xylella species. It was determined that PD1311 is required for virulence, as the deletion mutant, ΔPD1311, was unable to cause disease on grapevines. The ΔPD1311 strain was impaired in behaviours known to be associated with PD development, including motility, aggregation and biofilm formation. ΔPD1311 also expressed enhanced sensitivity to H 2 O 2 and polymyxin B, and showed reduced survival in grapevine sap, when compared with wild-type X. fastidiosa Temecula 1 (TM1). Following inoculation, ΔPD1311 could not be detected in grape shoots, which may be related to its altered growth and sensitivity phenotypes. Inoculation with ΔPD1311 2 weeks prior to TM1 prevented the development of PD in a significant fraction of vines and eliminated detectable levels of TM1. In contrast, vines inoculated simultaneously with TM1 and ΔPD1311 developed disease at the same level as TM1 alone. In these vines, TM1 populations were distributed similarly to populations in TM1-only inoculated plants. These findings suggest that, through an indirect mechanism, pretreatment of vines with ΔPD1311 suppresses pathogen population and disease. © 2016 BSPP AND JOHN WILEY & SONS LTD.

Tanto a visualidade espetacular como a visualidade médica colocam em questão o estatuto do Real corporal e oferecem a imagem do corpo como o próprio corpo, um corpo que é ao mesmo tempo real e virtual. O corpo virtual é um ícone da cultura do espetáculo, na qual a imagem atinge uma materialidade singular que compete pelo estatuto de realidade com a materialidade do corpo físico. A esse modelo se opõe nossa experiência encarnada do corpo físico unificado, como sujeito de ação no mundo, que implica o conjunto dos sentidos e que escapa na mera apreensão visual e objetivante da mídia e das tecnologias de imageamento.

Both spectacular and medical visuality challenge the statue of the corporal real and offer the body's image as the body itself, a body which is both real and virtual. The virtual body is an icon of the culture of the spectacle, in which the image achieves a unique materiality that competes with the materiality of the physical body for the statute of reality. Opposed to this model is our incarnate experience of the unified physical body as the subject of action in the world, involving our senses as a whole and escaping in the mere visual and objectifying grasp of the media and imaging technologies. Thus, the immaterial embodiment of

    Full Text Available El acelerado avance de la tecnología permite que las tecnologías emergentes sean accesibles por todos los usuarios. Ejemplos de estas tecnologías son la Realidad Aumentada y la Reconstrucción 3D, que gracias a dispositivos como tabletas o teléfonos inteligentes, pueden utilizarse de manera ubicua. Éstas tienen un enorme potencial en el campo de la educación, ya sea como recurso para entender conceptos complejos, como para motivar el aprendizaje de nuevos contenidos. El desafío de estas tecnologías es integrarlas para que sean accesibles y fáciles de utilizar por los docentes y los alumnos. En este trabajo presentamos una metodología para motivar el aprendizaje tanto en tareas de campo, mediante el uso de la Reconstrucción 3D, como en el ámbito escolar mediante libros aumentados. Por medio de un caso de estudio introducimos la Reconstrucción 3D de elementos fósiles de un sitio paleontológico bonaerense, para luego incorporar estos contenidos generados en un libro aumentado. A partir de la digitalización de huellas y fósiles de sitios paleontológicos, se obtuvieron modelos 3D que se integraron en un ambiente de aprendizaje inmersivo en el aula mediante los libros aumentados. Presentamos las opiniones de docentes de distintas disciplinas, que resaltan las posibilidades de esta metodología para su inclusión en el ámbito educacional regional.

Se revisan aspectos del debate sobre el castigo físico -como elemento significativo del proceso de occidentalización de América-, desde los discursos en la documentación judicial, en los textos jurídicos referidos a las penas aflictivas en el sistema colonial penal y el debate sobre la mortificación corporal en el ámbito religioso. Teórica y metodológicamente se trabaja desde la historia de las mentalidades y del cuerpo usando las propuestas teóricas de David Le Breton, Mary Douglas, Norbert Elias, René Girard y Serge GruzinskiThis work centres on two gradual processes that in spite of not being chronologically consecutive are necessarily joined: the penalty of the physical punishment like a judicial sentence and the privatization of the mortification of the body, or the step of the external constraint to the auto-constraint. Both topics allow to understand the modernity as process of privatization of the body from the gestures of "ennoblement of the body" and of "pity for the body ". For this purpose, we will check the debates on the physical punishment as significant element of the process of "occidentalización" of America, from the judicial speeches referred to distressing sentences in the colonial penal system and the debate on the corporal mortification in the religious area.

Sobre este marco general, revisaré la noción de “utopía feminista” como transgresión al modelo canónico y, a su vez, desafío al orden social considerado “natural”. Para ello, examinaré algunos problemas vinculados a la caracterización de la literatura utópica como tal, y el frecuente abandono de sus fundamentos filosóficos.

    Hepatitis B and Hepatitis C are amongst the leading causes of morbidity and mortality in pregnant women throughout the globe. This study is aimed at determining the frequency of these infections among primigravid females and the common factors that make them prone to these infections. Methods: This cross-sectional study was conducted at Ayub Teaching Hospital, Abbottabad from December 2015 to May 2016. A total of 174 jaundiced primigravida patients were included in the study through non-probability consecutive sampling. Blood samples were sent for HBsAg and anti-HCV ELISA. Samples were analysed by the pathologist with more than 5 years clinical experience. All data will be analysed using SPSS-16. Results: The mean age of the subjects was 24±5.7 years. Six (3.4%) patients were HBsAg positive and 13 (7.5%) were anti-HCV positive. About 9% of patients had undergone surgery in their life and 1.7% reported having received blood transfusion during their life. Thirty-two of them had history of intravenous or intramuscular injections. History of piercing of body part mostly ear-piercing for ornaments was present in 170 (97.7%) respondents. However, the frequency of blood transfusion, surgery and body piercing was not statistically significantly between HBsAg positive, HBsAg negative, and anti-HCV positive and negative patients (p>0.05). Conclusion: The incidence of these viral infections in our community is on the rise. It emphasizes the need of routine antenatal screening in pregnant ladies for these viruses and to educate the public about preventive measures against these infections. (author)

A partir dessa perspectiva, as destrezas corporais próprias da atividade bélica ou da prática lúdica cavalheiresca constituem um aspecto de menor relevância; somente uma expressão dessa sensibilidade, uma vez que o fundamental é que manifesta o relativo declínio da idéia de estirpe e dos atributos do sangue como dispositivso determinantes da excelência, processo que abriria espaço a um crescente interesse educativo pela instrução do corpo para além do exercício ou do mero endurecimento físico. A partir da perspectiva de Norbert Elias, exposta em O processo civilizatório, se mostram alguns exemplos literários da pujança dessa nova sensibilidade na literatura castelhana da baixa Idade Média.Palvras-chave: educação do príncipe, corpo, cortesía, literatura medieval castelhana.  THE BODY AS EDUCATIONAL CONTENT IN LATE MEDIEVAL SPANISH PROSE: 13TH AND 14TH CENTURIES AbstractThis paper advances the following hypothesis: physical education in the Middle Ages originates mainly in the emergence of a new sensibility, exhibited in control of gestures, posture and speech. Thus, the physical strength and bodily skills required of a knight in order to face combat represent an expression, among many others, of this new chivalrous sensibility, which would eventually lead to the decline of the concepts of lineage and blood as supreme marks of nobility and excellence, as well as to a growing educational interest in the instruction of the body, beyond mere physical exercise and training. Following the theory proposed by Norbert Elias in his Process of civilization, this paper aims to offer a selection of literary examples of this new sensibility

    Full Text Available Los patrones de asentamiento son las pautas con las que distribuyen los diferentes elementos construidos, como casas, caminos, campos, espacios públicos o fábricas, y son una expresión cultural de la sociedad que los construye. Tanto el tipo de elementos, su número como su distribución, dependen del nivel tecnológico, de la estructura social y de su bagaje cultural. Se puede decir, por tanto, que en los patrones estaría reflejado el conocimiento que la sociedad tenia del medio, así como sus anhelos, prioridades e, incluso, sus malas prácticas. La presente comunicación propone que estos patrones puedan servir de base para el planeamiento territorial actual, no sólo preservando aquello que realmente tenga valor, sino incluso recreándolos o reproduciéndolos a otras escalas siempre que puedan aportar un valor añadido al territorio. El escrito plantea una pregunta: ¿Qué se debe mantener de los patrones tradicionales y qué se puede, o incluso se debe, cambiar?, y para responderla en la primera parte se analizan someramente algunos asentamientos-tipo y en la segunda se indican pautas de actuación que han aparecido como propuestas en planes de ordenación territorial en los últimos años.

    Pickersgill, M J; Arrindell, W A

    1994-01-01

    Pierce and Kirkpatrick (1992, Behaviour Research and Therapy, 30, 415-418) addressed the finding that men reported lower levels of fear than women in response to specific fear items and concluded on the basis of their experiment that this was because the men were lying. Their conclusion is questioned on various grounds, including inappropriate statistical analyses, inadequate treatment of physiological data, failure to address the possibility of sample selection bias (signalled by the high drop-out rate) and the inadequacy of self-assessed fear measures based on a small number of single items. An alternative interpretation of their data is offered, based on the inverse correlation between initial response level and size of increment, demonstrable in their study in males but not in females. It is argued here that the increments may have been due to anticipatory arousal, a mediating factor that would also account for the facilitation of generalization between certain specific items. It is further suggested that, if this explanation is correct, the men were acting with more rather than less honesty, and it may on the other hand be the reports of the females that were affected by their sex-role stereotype. Another possible explanation of the findings is discussed. If men relatively high in masculinity had a greater tendency to drop out, the experimental sample at the second testing would be biased towards men relatively low in masculinity and reporting higher fear levels.

    Ethylene is a stress hormone with contrasting effects on herbivore resistance. However, it remains unknown whether these differences are plant- or herbivore-specific. We cloned a rice 1-aminocyclopropane-1-carboxylic acid (ACC) synthase gene, OsACS2, whose transcripts were rapidly up-regulated in response to mechanical wounding and infestation by two important pests: the striped stem borer (SSB) Chilo suppressalis and the brown planthopper (BPH) Nilaparvata lugens. Antisense expression of OsACS2 (as-acs) reduced elicited ethylene emission, SSB-elicited trypsin protease inhibitor (TrypPI) activity, SSB-induced volatile release, and SSB resistance. Exogenous application of ACC restored TrypPI activity and SSB resistance. In contrast to SSB, BPH infestation increased volatile emission in as-acs lines. Accordingly, BPH preferred to feed and oviposit on wild-type (WT) plants--an effect that could be attributed to two repellent volatiles, 2-heptanone and 2-heptanol, that were emitted in higher amounts by as-acs plants. BPH honeydew excretion was reduced and natural enemy attraction was enhanced in as-acs lines, resulting in higher overall resistance to BPH. These results demonstrate that ethylene signaling has contrasting, herbivore-specific effects on rice defense responses and resistance against a chewing and a piercing-sucking insect, and may mediate resistance trade-offs between herbivores of different feeding guilds in rice. © The Author 2014.

    Comet C/2012 S1 (ISON) is unique in that it is a dynamically new comet derived from the Oort cloud reservoir of comets with a sun-grazing orbit. Infrared (IR) and visible wavelength observing campaigns were planned on NASA's Stratospheric Observatory For Infrared Astronomy (SOFIA) and on National Solar Observatory Dunn (DST) and McMath-Pierce Solar Telescopes, respectively. We highlight our SOFIA (+FORCAST) mid- to far-IR images and spectroscopy (approx. 5-35 microns) of the dust in the coma of ISON are to be obtained by the ISON-SOFIA Team during a flight window 2013 Oct 21-23 UT (r_h approx. = 1.18 AU). Dust characteristics, identified through the 10 micron silicate emission feature and its strength, as well as spectral features from cometary crystalline silicates (Forsterite) at 11.05-11.2 microns, and near 16, 19, 23.5, 27.5, and 33 microns are compared with other Oort cloud comets that span the range of small and/or highly porous grains (e.g., C/1995 O1 (Hale-Bopp) and C/2001 Q4 (NEAT) to large and/or compact grains (e.g., C/2007 N4 (Lulin) and C/2006 P1 (McNaught)). Measurement of the crystalline peaks in contrast to the broad 10 and 20 micron amorphous silicate features yields the cometary silicate crystalline mass fraction, which is a benchmark for radial transport in our protoplanetary disk. The central wavelength positions, relative intensities, and feature asymmetries for the crystalline peaks may constrain the shapes of the crystals. Only SOFIA can look for cometary organics in the 5-8 micron region.

O objetivo desta pesquisa é analisar o karate por meio de sua espiritualidade, já que, junto aos textos fundamentais de sua tradição recente, ela é tida como a essência presente em todas as dimensões da expressão da arte. Para tanto, vale-se de uma metodologia historiográfica de perspectiva fenomenológica. Karate-do veicula a espiritualidade do esvaziamento como norte de sua filosofia corporal. Temas com linhas fronteiriças tênues entre si são analisados pela perspectiva de tal espiritualidade.

    Full Text Available El episodio mítico de Hércules fulminando los considerados fundamentos del vínculo social por un ataque de pasión ciega nos introduce en la problemática del tratamiento de la afectividad en la antropología. El artículo señala que el interés que las ciencias humanas muestran por la afectividad conlleva no sólo la abertura definitiva de un campo de la actividad social fundamental, sino una reflexión sobre las formas de conocimiento en estas disciplinas. En efecto, a diferencia de otros campos de estudio que se han ido proponiendo a lo largo de la historia de nuestras disciplinas, plantear la afectividad como objeto de análisis tiene repercusiones sobre la forma de aproximarse al objeto, porque la existencia misma de una dimensión afectiva obliga a redefinir la dimensión cognitiva propia del acto de conocer. En este artículo, planteo algunos elementos metodológicos que se derivan de estas ideas.O episodio mítico de Hercules fulminando os fundamentos considerados do vinculo social por um ataque de paixão cega, coloca nos na problemática do tratamento da afetividade na antropologia.
