Hårvårdsverksamheter ur ett miljö- och hälsoskyddsperspektiv : Kartläggning av frisörer i Danderyd och Vaxholm och utarbetande av checklista för inspektionerWelander, Mattias January 2009 (has links)
<p>Hair care is a hygienic treatment and is supervised by the Local Environment and Public Health Committee in the municipality. According to the Swedish Environmental Code, hairdressers as all practitioners are required to take measurements to protect the environment and public health. In hygienic treatments hazards may arise from inadequate hygiene practice which spread infection. Hazards may also arise from the use of hair care products such as permanent wave solutions, bleaches and hair dyes. Some hair dye components are known to cause contact allergy, mostly in hair dressers who are exposed professionally but also in some cases in consumers. Bleaches increase the risk of occupational asthma in hairdressers. Some studies have shown an increased risk of cancer in hairdressers and possibly also in consumers. The use of cosmetic and hygienic products also affects the environment. Some components, e.g. surfactants, are hazardous to aquatic organisms, even though the contribution from hair care products is relatively small. Some hairdressers perform ear piercing. All activities that penetrate the skin involve a risk of infection. There is also a risk of developing a nickel allergy if the earrings are not nickel free. In Sweden, due to recently changed legislation, hairdressers no longer need to notify the Local Environment and Public Health Committee before starting a practice. The changes also mean that the rules about documentation of the measurements practitioners need to take to protect public health are less clear. The changes have made the supervision of hairdressers harder for the Local Environment and Public Health Committee.</p>

Öronhåltagning hos frisörer och i guldsmedsbutiker i Umeå : Egenkontroll, lokal och hygien / Ear piercing in hairdressing salons and jewellery shops in Umeå : A study of current hygiene conditions on siteVikman, Helena January 2012 (has links)
Ear piercing performed in hairdressing salons and jewellery shops using a piercing gun has been set aside from the obligation to notify the local environmental and public health authorities, due to the use of disposable cassette with the piercing gun. According to the Swedish environmental code each practitioner are required to prevent any health hazards arisen from the operation. Local bacterial infection is the most frequent complication associated with the ear piercing procedure and to prevent the potential risk of such an event, hygiene conditions in both the premises and in procedures are essential. The purpose of the report was to examine the presence of ear piercing practitioners in Umeå and their current hygiene conditions. The study consisted of interviews with employees and managers on site whose answers was evaluated and compared to the general recommendations of The National Board of Health and Welfare. The study indicates that most of the shops had appropriate premises and proper hygiene methods. However merely half of the shops never seemed to clean nor disinfect the ear piercing gun, which may be considered to be non negligible deficiency in current methods. One salon had questionable methods which may require a follow-up. The conclusion of this study is that more information within the various practitioners is required in most cases to increase consciousness of proper and safe course of action.

As sanções da Lei de Licitações e a desconsideração da personalidade jurídica / The public bidding laws sanctions and the disregard of the legal entityFernando Moreno Machado 03 April 2014 (has links)
Dissertação voltada ao estudo das sanções administrativas previstas na Lei Federal 8.666/1993 (Lei de Licitações). Apresenta quadro panorâmico das licitações e contratações públicas no Direito Administrativo Brasileiro. Trata do regime jurídico do exercício da atividade sancionatória pela Administração Pública, com destaque para os princípios regentes da matéria. Examina as discussões teóricas, doutrinárias e jurisprudenciais relativas à aplicabilidade das sanções administrativas previstas nos artigos 86 a 88 da Lei de Licitações, como a multa, a advertência, a suspensão temporária de participação em licitação, o impedimento de contratar com a Administração e a declaração de inidoneidade, aí incluindo a competência para imposição de sanções, os sujeitos passivos das penalidades aplicáveis, além das nuances de cada uma delas. Destaca a controvérsia estabelecida acerca das distinções e abrangência dos efeitos das penas de suspensão temporária, impedimento de contratar e declaração de inidoneidade. Estuda a possibilidade de a Administração Pública fazer uso da Teoria da Desconsideração da Personalidade Jurídica, inicialmente em um cenário de ausência de autorização legislativa, como forma de incremento da efetividade daquelas sanções, quando constatado o abuso de direito dos particulares ao constituírem novas sociedades, com o intuito de burlá-las. Examina a Lei Federal 12.846/2013, que trata da responsabilização de pessoas jurídicas pela prática de atos contra a Administração Pública, e suas consequências na seara das licitações e contratações administrativas. / Dissertation focused on the study of administrative sanctions under Federal Law no. 8.666/1993 (public bidding Law). It presents an overview of public bidding and public hiring under Brazilian administrative law. It presents the legal regime of the sanctioning activity exercised by public authorities, especially the matter governing principles. It examines the theoretical, doctrinal and jurisprudential discussion concerning the applicability of administrative sanctions established by Articles 86 to 88 of the Public Bidding Law, such as fines, warnings, temporary suspension from participating in public biddings, the impediment to contract with the government and the unfitness declaration, including the power to impose sanctions, the subjects liable of applicable penalties, and the nuances of each one of these penalties. It highlights the controversy about the distinctions and comprehensiveness of the effects related to the temporary suspension, avoidance of contract and declaration of unfitness. It analyses the possibility of public administration adopt the theory of piercing of the corporate veil, initially in a scenario of absence of legislative authorization, as a way of increasing the effectiveness of those sanctions when found abuse of the right of individuals which constitute new associations in order to chouse them. It examines the Federal Law No. 12.846/2013, which deals with the liability of legal entities for the commission of acts against the government and its consequences on the public bids and administrative hires area. Keywords: administrative penalties, sanctions under administrative law, principle of typicality, extension effects of penalties, piercing of the corporate veil.

Laser cutting and piercing: Experimental and theoretical investigationPocorni, Jetro January 2017 (has links)
This thesis concerns experimental investigations of laser cutting and piercing, with theoretical and practical discussions of the results. The thesis is made up of an introduction to laser cutting and six scientific Papers. These Papers are linked in such a way that each of them studies a different aspect of laser cutting: process efficiency in Paper I, morphology and melt flow on the laser cut front in Papers II, III and IV and laser piercing in Papers V and VI. Paper I investigates the effect of material type, material thickness, laser wavelength, and laser power on the efficiency of the cutting process for industrial state-of-the-art CO2 and fibre laser cutting machines. Here the cutting efficiency is defined in its most fundamental terms: as the area of cut edge created per Joule of laser energy. In Paper II a new experimental technique is presented which has been developed to enable high speed imaging of laser cut fronts produced using standard, commercial parameters. The results presented here suggest that the cut front produced when cutting 10 mm thick medium section stainless steel with a fibre laser and a nitrogen assist gas is covered in humps which themselves are covered in a thin layer of liquid. Paper III presents numerical simulations of the melt flow on a fibre laser ablation-driven processing front during remote fusion cutting, RFC. The simulations were validated with high speed imaging observations of the processing front. The simulation results provide explanations of the main liquid transport mechanisms on the processing front, based on information on the temperature, velocity and pressure fields involved. The results are of fundamental relevance for any process governed by a laser ablation induced front. In Paper IV cutting fronts created by CO2 and fibre lasers in stainless steel at thicknesses between 2 mm and 10 mm have been ‘frozen’ and their geometry has been measured. The resulting three-dimensional shapes have been curve fitted as ninth order polynomials. Various features of the cutting front geometry are discussed, including the lack of correlation of the cut front inclination with either the relevant Brewster angle or the inclination of the striations on the cut edge. In this paper, mathematical descriptions of the cutting fronts are obtained, which can be used as input parameters by any researcher in the field of laser cutting simulations. Paper V investigates the subject of laser piercing. Before any cut is started the laser needs to pierce the material. In this paper the laser piercing process is investigated using a wide range of laser pulse parameters, for stainless steel using a fibre laser. The results reveal the influence of pulse parameters on pierce time and pierced hole diameter. A high speed imaging camera was used to time the penetration event and to study the laser-material interactions involved in drilling the pierced holes. In Paper VI a ‘dynamic’ or ‘moving beam’, laser piercing technique is introduced for processing 15 mm thick stainless steel. One important aspect of laser piercing is the reliability of the process because industrial laser cutting machines are programmed for the minimum reliable pierce time. In this work a comparison was made between a stationary laser and a laser which moves along a circular trajectory with varying processing speeds. High speed imaging was employed during the piercing process to understand melt behavior inside the pierce hole. Throughout this work experimental techniques, including advanced high speed imaging, have been used in conjunction with simulations and theoretical analysis, to provide new knowledge for understanding and improving laser beam cutting and its associated piercing process.

Implementation of nut piercing from below in a stamping die : A case study at Volvo Car Body Components / Implementering av mutterstansning underifrån i ett pressverktyg : En fallstudie på Volvo Car Body ComponentsHåkansson, Maja January 2021 (has links)
In today's car industries, low investment costs and high production rates are sought. By using nut piercing in the stamping dies in the manufacture of body components, otherwise necessary subsequent tempos can be reduced. The goal of the work was to implement nut piercing from below in a reference die to be able to use this type of operation in future projects. The main problem when implementing nut piercing from below is to be able to handle and evacuate the scrap piece that remains after the punching. By studying the equipment in the reference die, a deeper understanding of the process could be obtained, at the same time as information and necessary material were collected by expertise and the case company's suppliers for nut piercing. The recommendation to the case company provides a solution proposal for scrap evacuation as well as the components involved to be able to carry out the operation.

Evolutionary Studies of Fruit-Piercing Moths in the Genus Eudocima Billberg (Lepidoptera: Erebidae)Crystal Klem (7053191) 16 October 2019 (has links)
<p>The
prevalence of monoculture and landscape simplification is correlated with
diminished biodiversity and increased presence of harmful pest species in crop
environments. Lepidoptera is the largest clade of herbivorous insects, with
many agriculturally significant species. The pest status of insects in agricultural settings is human-defined
based on behaviors that may negatively impact the yield of susceptible crops.
As such, both the insect behavior and the affected crop play a part in
determining pest status. One helpful means of understanding pest status
involves using pest injury guilds, which distinguish different pest groups
based on similar kinds of injury to comparable plant tissues. Pest injury
guilds defined in the literature are reviewed and then applied to
agriculturally-significant Lepidoptera. Specialized Lepidoptera behaviors are
reviewed within their respective injury guilds, and the systematics, ecology,
and control options for fruit-piercing moths are discussed within the context
of pest Lepidoptera behaviors. To address the need for distribution information
for economically relevant Lepidoptera, the first annotated checklist of
pest Lepidoptera is also provided for the United States and Canada. This
checklist includes 80 agriculturally significant Lepidoptera species and
complexes, and incorporates notes on distribution, species delimitation,
natural history, and establishment.<br></p>
<p><b> </b></p>
<p>Fruit-piercing
moths in the genus <i>Eudocima</i> Billberg,
1820 have significant pest status as adults rather than as larvae, and directly
injure fruits using a specially-adapted proboscis. There are at least 48 <i>Eudocima</i> species which are found in the
world’s tropics, but confusion persists in the classification of this genus and
there are several suspected complexes. Additionally, the area of origin for
this group is uncertain, although the Oriental region has been postulated. A
comprehensive phylogenetic analysis of <i>Eudocima</i>
is conducted using 82 morphological characters, which are each described and
figured, and analyzed using parsimony. Results suggest that <i>Eudocima</i> is not monophyletic. Strongly-resolved
relationships were recovered, although these did not correspond with previous
generic concepts. The Australian region is recovered as the most parsimonious
area of origin for <i>Eudocima</i>, and
patterns of dispersal, particularly between the Oriental and Australian regions
along the Indo-Australian Archipelago, are discussed.</p>
<p> </p>
<p>The <i>Eudocima phalonia</i>-complex is distributed
throughout the Old World and has been the subject of increasing interest and
research due to its economic impact in the tropics and status as a potential
invasive species. The recent description of closely-related sister species, as
well as morphological variation documented within <i>E. phalonia</i> itself, suggests possible speciation occurring within <i>E. phalonia</i> populations across its wide
geographic range. To test species boundaries for this taxon, a molecular
phylogeny is constructed using anchored hybrid enrichment and a next-generation
sequencing approach. Sampling for this phylogeny was informed using a global
range map for <i>E. phalonia</i>, which was
developed using georeferenced specimen data from natural history collections.
Biogeographic analyses are also conducted to investigate the area of origin and
dispersal patterns of <i>E. phalonia</i>,
and to examine possible speciation modes and gene flow. Georeferenced range
information is also utilized along with environmental variables in constructing
a correlative environmental niche model using MaxEnt, which is used to evaluate
a previous mini risk assessment for environmental suitability in the
continental United States for <i>E. phalonia</i>
establishment. Results suggest that <i>E.
phalonia</i> is monophyletic, with gene flow still occurring between
populations. The area of origin for <i>E.
phalonia</i> is postulated to be the Oriental region, although further
investigation is needed. Range predictions for <i>E. phalonia</i> from environmental modelling were performed for both the
Old World, which concurred well with occurrence data, and for the New World. Assessment
of environmental suitability for <i>E.
phalonia</i> in the continental United States suggests areas in Florida and
along the Gulf Coast are most favorable for establishment.</p>

La performance dans les arts plastiques aujourd'hui : tatouages et piercingsSouladie, Catherine 26 June 2012 (has links) (PDF)
Cette recherche propose une réflexion sur la pertinence d'un " art -action " actuel, à partir d'une analyse d'actes pour l'art, caractérisés comme " hors limites ", à travers une utilisation de la présence physique comme essence et support de l'art plastique, entreprise dès les années 1920 par Marcel Duchamp, et déclinée durant tout le vingtième siècle avec des mouvements artistiques tels Dada, le Happening, l'Actionnisme Viennois, ou l'Art Corporel.Nous étudions ici, aidés d'artistes performers choisis autour de quelques pratiques singulières de Albrecht Becker, Ron Athey et Lukas Zpira, les possibles limites d'actes artistiques, mettant en scène de façon extrême, à travers des performances jugées choquantes, agressives, incluant piercings, tatouages, osant parfois un art du malaise, se jouant des conventions, des tabous et des codes sociaux et culturels en place. Ainsi nous voyons s'il y a lieu, aujourd'hui, de parler encore d'actes artistiques politiques, militants, après l'âge d'or des années soixante-dix, parmi des nouvelles esthétiques du corps humain, celui-ci successivement " héros, sujet, matériau, objet, victime, écran " de cet art-action transgressif. Notre volonté est de saisir l'ambiguïté contenue dans la représentation, et toute la symbolique donnée à voir, par rapport à une première intention qui est une certaine déstructuration à la fois thématique et formelle dans les arts plastiques. La discussion est donc engagée sur l'authenticité et la pérennité de ces pratiques artistiques extrémistes, transgressives, manipulant le concept d'identité ou même la génétique, discussion aussi sur leur statut avant-gardiste dans l'histoire de " l'art pour l'art ", concept porté par la modernité.Ce " hacking " du corps nous amène-t-il-alors vers un devenir post-humain virtuel, une seule existence dans les univers numériques ? Le corps est-il en perdition ou, paradoxalement l'ultime recours, sauvé par ces modifications douloureuses et radicales ?

A Boundary Element Method for the strongly nonlinear analysis of ventilating water-entry and wave-body interaction problemsVinayan, Vimal 15 February 2012 (has links)
A two-dimensional Boundary Element Method (BEM) is developed to study the strongly nonlinear interaction between a surface-piercing body and the free-surface. The scheme is applied to problems with and without the possibility of ventilation resulting from the motion and geometric configuration of the surface-piercing body. The main emphasis of this research work is on the development of numerical methods to improve the performance prediction of surface-piercing propellers by including the whole range of free-surface nonlinearities. The scheme is applied to predict the ventilated cavity shapes resulting from the vertical and rotational motion of a blade-section with fully nonlinear free-surface boundary conditions. The current method is able to predict the ventilated cavity shapes for a wide range of angles of attack and Froude numbers, and is in good agreement with existing experimental results. Through a comparison with a linearized free-surface method, the current method highlights the shortcomings of the negative image approach used commonly in two-dimensional and three-dimensional numerical methods for surface-piercing hydrofoils or propellers. The current method with all its capabilities makes it a unique contribution to improving numerical tools for the performance prediction of surface-piercing propellers. The scheme is also applied to predict the roll and heave dynamics of two-dimensional Floating Production Storage and Offloading (FPSO) vessel hull sections within a potential flow framework. The development of the potential flow model is aimed at validating the free-surface dynamics of an independently developed Navier Stokes Solver for predicting the roll characteristics of two-dimensional hull sections with bilge keels. / text
