The following research was completed with an understanding that there is much to know about women who use intravenous drugs (WUID). The extant literature about the lives of people who use intravenous drugs (PWID) is mostly quantitative, highly androcentric, and primarily focused on HIV transmission. What is needed is information about the culture of WUID and the circumstances contributing to their poor health both from drug use and the conditions in which they live. The ethnographic study involved (a) collecting artifacts, including photographs taken by the women, (b) observing participants during some of their daily activities and primary healthcare interactions, and (c) face-to-face interviews with WUID. The results portray a life that closely resembles that which is known, but also the findings enable a lens into (a) the vicious circle associated with obtaining drugs and survival, (b) the violence, both systemic and personal, that homeless, urban-living WUID in Canada endure, and (c) the importance of “being clean” that directs much of their activities and presentation. From a theoretical perspective, the study enabled a deepened understanding of the importance of the continuum of cleanliness and how it interfaces with what the women believe. In summary, WUID have received unjust opportunities to care for themselves given the current laws and stigmatization that forces them to remain hidden, perform illegal activities, avoid discrimination, and fend for themselves in a world that perpetuates the hegemony of white middle-class Western peoples. The results provide a direction for healthcare in terms of WUID. Primarily there is a need to engage WUID in establishing what would work for them and thus incorporating peers in the process of initiating and maintaining services. Clearly established is a need for drug use to be decriminalized to allow WUID to gain recognition, to avoid criminality, and to re-enter the world that belongs as much to them as any other.

Esta dissertação apresenta o desenvolvimento de um equipamento para a execução de estacas escavadas com injeção sob pressão, logo após a fase de escavação, de argamassa de cimento e areia. O processo utiliza segmentos de trados que são introduzidos no solo através da combinação de rotação e empuxo axial de compressão. A extração dá-se simultaneamente à injeção de argamassa, e o monitoramento das pressões de injeção é feito através de um manômetro, com o objetivo de garantir a integridade do fuste. Um motor a diesel fornece até 92 kW a 1800 rpm e é responsável pelo acionamento dos diversos conjuntos hidráulicos. O equipamento, montado numa plataforma sobre pneus, é autopropelido e autocarregável podendo ser transportado em caminhões comuns com dois eixos traseiros. Esse tipo de estaca, denominado estaca hélice segmentada, poderá representar uma alternativa interessante às estacas tradicionais, principalmente em locais onde as construções vizinhas possam sofrer danos devido à utilização de estacas de deslocamento ou onde os custos envolvidos na utilização de equipamento mais pesado e sofisticado possam inviabilizar a sua aplicação / This work presents the development of equipment for execution of segmented auger piles with injection of cement mortar under pressure, soon after the excavation phase. The process uses segmented augers that are installed in the ground through the rotation and pull-down combination. The extraction is made at the same time as the cement mortar injection and the injection pressures are monitored by a manometer, to assure the shaft integrity. A diesel motor offers up 92 kW at 1800 rpm and is responsible for the movement of several hydraulic units. The equipment mounted on a tire platform, is self-propelling and can raise itself to be loaded onto common trucks. This kind of pile, called segmented pile, will be an interesting alternative for the traditional piles, mainly at sites where the neighboring constructions will be damage by the utilization of the displacement pile, or where the costs involved in the utilization of heavier and sophisticated equipment can make its application unfeasible

abstract: Opioid use in the United States is skyrocketing. Overdose deaths have increased 433% in the last decade and will continue climbing. In addition to the mortality caused by illicit opioid misuse, morbidity rates have also risen. People Who Inject Drugs (PWID) demonstrate higher rates of Human Immunodeficiency Virus (HIV), Hepatitis C Virus (HCV), Endocarditis, Persistent Abscesses, Staphylococcus Aureus (S. aureus, Staph) and other skin infections. This thesis serves as (1) a systematic review of the differences in health conditions experienced by PWID and (2) an examination of the trends in skin and soft tissue infection from a small sample in Phoenix, Arizona. The author argues that PWID suffer from an increased rate of comorbid conditions associated with substance use. Targeted social work interventions could be useful in reducing the rates of disease and their impact on the individual and community. / Dissertation/Thesis / Masters Thesis Social Work 2019

Background: Women who inject drugs continue to represent a disproportionate percentage of new cases of HIV in Canada (PHAC, 2006). However, in Nova Scotia, HIV has still not been conceptualized as a major health issue, especially among women (Gahagan, Rehman & Baxter, 2006). At the same time, recent research findings suggest that female injection drug users in Nova Scotia are engaging in unsafe injection and sexual practices and often lack access to harm reduction-based programming and resources (Ploem, 2000; PHAC, 2006; Jackson et al., 2010; Parker et al., 2011; Hodder, 2011). In a provincial context of high prevalence of injection drug use and HIV risk behaviours, preventing increasing rates of HIV infection will depend on the development of proactive and gender-informed HIV prevention policies. Purpose: This study had two main aims. First, it aimed to chart the development of provincial HIV prevention and harm reduction policies and to identify how, and if, the policy development processes address the HIV prevention needs of women who inject drugs. Its second aim was to identify key barriers and facilitators to developing HIV prevention policy for women who inject drugs in Nova Scotia. Methods: This study involved a review of key HIV prevention and harm reduction policy documents as well as interviews with 27 key informants directly involved with HIV prevention and/or harm reduction policy decision-making. Findings/Discussion: The existing Nova Scotia-based policy development network, their policies, their processes and the context within which they have functioned over the past ten years do not appear to be supporting the development of HIV prevention and harm reduction policy which addresses the needs of women who inject drugs. Policy committee composition lacked inclusivity and organizations that work directly with women who inject drugs held less influence in policy processes. In addition, gender was not prioritized by decision-makers and therefore not comprehensively addressed in policy content. As a result, the needs of women who inject drugs have not been prioritized in policy processes and subsequently few targeted resources are going to the community-based organizations that provide services to these women.

Master of Public Health - MPH / Gay men and other men who have sex with men (MSM) and a subset within this group who are people who inject drugs (PWID) face difficulties when trying to access humanimmune deficiency virus (HIV)/ anti-retroviral treatment (ART) services and adhere to ART, due to the intersecting forms of oppression they face. Current interventions to address adherence to ART are mostly bio-medical in nature, and support the presumption that individual-level factors are the most pertinent barriers to adherence to ART. This mini-thesis presents findings from a qualitative study that explored individual, health systems and structural factors that shape experiences of adherence to ART amongst gay men and other MSM and a subset within this group who are PWID

The dissertation is concerned with automatization proposal of simple injection moulds for plastics. The dissertation is concentrating on the process of CAD design with the aim of make it more effective and automate by the help of 3D parametric strickle board of moulds. It serves for rapid proposal of basic mechanism of the tools. Strickle board of the mould is managed by length of side moulding plate in required range from 300 to the 700mm. For managing of standardized parts was created web portal, which includes database of single parts. These parts can be simply insert to the groups of moulds by the help of hypertext links in software Catia V5. Dissertation includes description of whole system automatization and matching of the new way of CAD design with the original.
