Arbetet handlade om att utreda energibehovet till följd av en industriport mellan ett fryslager och en utlastningsterminal, samt utreda om anläggningens golvvärme kan arbeta med sänkt temperatur för att minska uppvärmingen av fryslagret, båda delarna med syftet att identifiera energiförluster och kunna sänka energiåtgången. Energiförlusten till följd av porten identifierades genom uppmätning av luftflöden för att sedan beräknas över ett år med hjälp av en teoretisk modell. För att undersöka golvvärmens driftsparametrar gjordes en litteraturstudie för att bestämma ifall det vore tillrådligt att sänka dess arbetstemperatur. Slutsatsen blev att portens öppetvarande under år 2016 resulterade i omkring 145MWh i rent termisk energiförlust. Anläggningens vattenburna golvvärme drivs vid cirka 10-12°C vilket är enligt praxis och att en förändring av temperaturen därför inte kan rekommenderas. / This thesis was examining the energy demand due to an industrial gate dividing a freezer warehouse and it’s adjacent loading bay, as well as determining whether the facility’s sub-floor heating could be operated at a lower temperature setting in order to decrease the heat transfer into the freezer, both of which with the purpose to identify energy losses and possibly lower the total energy demand. The energy losses due to the gate were identified by measuring airflow and then calculate the loss over a whole year by means of a theoretical model. To examine the operating parameters of the sub-floor heating, a literature study was conducted in order to determine whether it would be feasible to lower its temperature. The conclusion was that the opening of the gate during year 2016 resulted in about 145MWh of purely thermal energy loss. The facility’s waterborne sub-floor heating is operated at around 10-12°C, which is according to practice, and a change of temperature cannot be recommended.

Due to the competitive nature of airline industry and the desire to minimise aircraft weight, there is a continual drive to develop lightweight, reliable and more comfortable seating solutions, in particular, a new generation slim economy seat. The key design challenge is to maximise the “living space” for the passenger, with strict adherence to the ‘Crash Safety Regulations’. Cranfield University is addressing the needs of airliners, seat manufactures and safety regulating bodies by designing a completely novel seat structure coined as “Sleep Seat”. A generous angle of recline (40 degree), movement of “Seat Pan” along the gradient, fixed outer shell of the backrest, and a unique single “Forward Beam” design distinguishes “Sleep Seat” form current generation seats. It is an ultra-lightweight design weighing 8kg (typical seat weight is 11kg). It has to sustain the static (CS 25.561) and dynamic (CS25.562) “Emergency landing” loads as specified by “Certification Specifications (CS). Apart from maintaining structural integrity; a seat-structure must not deform, which would impede evacuation, should absorb energy so that the loads transferred to Occupants are within human tolerance limits and should always maintain survivable space around the Occupant. All these parameters, which increase a life-expectancy in a ‘survivable’ crash, can be estimated using either experimental testing or virtual simulation tools such as “Finite Element Analysis (FEA). Design of the “Sleep Seat” is still in its conceptual phase and therefore experimental testing for all the design iterations involved is unrealistic, given a measure of the costs and timescales involved. Therefore focus of research is to develop practical and robust FE methodologies to assess static and dynamic performances of a seat-structure so as to compare different design concepts based on their strength, seat interface loads (a limit defined by strength of aircraft-floor), maximum deformations and cross-sectional forces ...

Wood is a material with an enormous number of applications. For decades, the development of wastewater treatment technologies tailored for the wood sector has focused on those industries that have water as an integral part of the industrial production, such as paper and pulp. However, there is a large and potentially growing sector that has been neglected, which is formed by industries in which water is not part of their production line, as for example, the wood floor and furniture industries (named wood-based dry industries). These industries still produces relatively low volumes of highly polluted wastewaters, with COD up to 30,000 mg/L, due to cleaning/washing procedure (named cleaning wastewaters). These cleaning wastewaters are often sent to the municipal wastewater treatment plant after dilution with potable water. Once there, recalcitrant pollutants are diluted and discharged into recipient water bodies or trapped in the municipal wastewater sludge. Another type of contaminated water these “dry industries” often generate in high volumes, and which is usually discharged with no previous treatment, is storm-water containing contaminants that have leached from large wood storage areas. The overall aim of this thesis was to increase the level of knowledge and competence and to present on-site wastewater treatment options for wood-based dry industries using the wood floor industry as a case-study, with a focus on combined treatment methods and solutions applicable to both the cleaning wastewater and storm-water. Among the treatment technologies investigated, electrocoagulation was studied both as a standalone treatment and combined with sorption using activated carbon. The combined treatment achieved a COD reduction of approximately 70%. Some advanced oxidation processes (AOP) were also studied: a COD reduction of approximately 70% was achieved by photo-Fenton, but the most successful AOP was ozone combined with UV light, were a COD reduction around 90% was achieved, with additional improvement in the biodegradability of the treated effluent. Ozone also proved to be effective in degrading organic compounds (approximately 70% COD reduction) and enhanced the biodegradability of the storm-water runoff from wood storage areas. The results have shown that the application of ozone can be considered an option for treatment of cleaning wastewaters and possibly for storm-water biodegradation enhancement. / Trä är ett material med ett stort antal möjliga användningsområden. Inom träindustrin har utvecklingen av vattenbehandlingsmetoder varit inriktat på de branscher som har vatten som en del av produktionen, såsom papper- och massaindustrin. Men det finns en stor och potentiellt växande sektor inom träindustrin som har försummats, den utgörs av industrier som inte har vatten som en del av produktionen, t.ex. trägolv och trämöbel industrier. Trots detta så producerar dessa industrier fortfarande relativt kraftigt förorenade avloppsvatten med t.ex. COD-värden upp till 30000 mg/l men i relativt låga volymer. Dessa avloppsvatten uppkommer vid rengöring av maskiner och städning av lokaler, varefter de oftast efter utspädning med dricksvatten skickas till det kommunala reningsverket. Väl där späds det förorenade vattnet vidare ut med annat inkommande vatten men passerar dock till stor del obehandlat och släpps ut i mottagande vattendrag eller så fastnar föroreningarna i avloppsslamet. Dagvatten är en annan typ av förorenat vatten från dessa "torra industrier" som ofta genereras i stora volymer och innehåller föroreningar som lakats från de trämaterial som förvaras i de stora upplag som ofta förekommer vid denna typ av industrier. Det övergripande syftet med avhandlingen var att öka kunskapen och kompetensen för att kunna miljömässigt riktigt och ekonomiskt billigt behandla industriavloppsvatten lokalt på plats inom trävaruindustrin, genom att använda en trä-golvsindustri som fallstudie. Fokus lades på kombinerade behandlingsmetoder och lösningar som skulle kunna vara lämpliga både för industriavloppsvatten och dagvatten. Ett antal behandlingstekniker har undersökts; elektrokoagulering studerades både som en fristående behandling och i kombination med aktivt kol. Den kombinerade behandlingen gav en COD-reduktion på ungefär 70 %. Flera avancerade oxidationsprocesser (AOP) studerades också, och en COD-reduktion på cirka 70% uppnåddes med en kombination av UV-ljus och Fenton behandling. Den mest framgångsrika behandlingen var ozon i kombination med UV-ljus där en COD-reduktion runt 90 % uppnåddes varvid en avsevärd förbättring av den biologisk nedbrytbarhet på det behandlade avloppsvattenet erhölls. Ozon visade sig också vara effektivt för nedbrytning av organiska föreningar (ca 70% COD reduktion) och förbättrade den biologiska nedbrytbarheten av föroreningarna i dagvattnet från den studerade industrin. Resultaten har visat att ozon kan anses vara ett lämpligt alternativ för att behandla industriavloppsvatten inom trävarusektorn och möjligen för att öka den biologiska nedbrytbarheten av dagvattnet från dessa industrier / Integrated Approach for Handling of Industrial Wastewater and Stormwater / Triple Helix Collaboration on Industrial Water Conservation in Småland and the Islands

A number of recent studies have found a strong link between peak global warming due to anthropogenic carbon dioxide and cumulative carbon emissions from the start of the industrial revolution. This thesis builds on this work by using a simple climate model to apply the concept of cumulative emissions to emission floors, by comparing cumulative emissions with other types of emissions target, and by extending the work to apply to noncarbon dioxide (CO₂) greenhouse gases and short-lived climate forcers (SLCFs). Though peak global warming correlates well with cumulative carbon emissions, the link to emissions over shorter periods or in the years 2020 or 2050 is shown to be weaker. It is also shown that the introduction of emissions floors does not reduce the importance of cumulative emissions, but may make some warming targets unachievable. For pathways that give a most likely warming up to about 4°C, cumulative emissions from pre-industrial times to year 2200 correlate strongly with most likely resultant peak warming in the simple model used, regardless of the type of emissions floor used. The maximum rate of CO2- induced warming is not determined by cumulative emissions but is shown to be limited by the peak rate of CO₂ emissions. A simple model of non-CO₂ greenhouse gases is also developed and used to investigate SLCFs. It is shown that emissions of SLCFs today have little impact on peak warming, and that delaying near-term reductions in SLCFs would not have a significant impact on peak warming. Only once CO₂ emissions are falling do SLCF emissions have a significant impact on peak warming. A global climate policy framework is presented as an example of how the work in this thesis could be used in policy. Future work is also discussed, particularly verification of these results in a more complex model.

Title: An examination of pelvic floor activity following the application of special exercises Objectives: The aim of this thesis is to validate the usefulness of carrying out local pelvic floor muscle examinations as an indication and education for therapy. A second objective is for the women involved in the research to subjectively evaluate the examination methods and therapy. Furthermore, the thesis aims to establish an example of a comprehensive and detailed local examination of the pelvic floor muscles. Methods: We measured the pelvic floor activity per vaginam using an EMG biofeedback device on clients with a pelvic floor dysfunction and grade I stress incontinence symptoms. Based on the results of the examination, therapy using the vaginal device was recommended and in six weeks a follow-up examination was carried out. The changes in pelvic floor activity were evaluated by comparing the initial and follow-up examinations. Thus the usefulness of carrying out an examination of the local pelvic floor muscles before indicating a therapy was validated. At the end of the examination an interview with participating clients was conducted in order to subjectively evaluate the method. Results: All of the women participating in the research had previously undergone a different method of pelvic floor...

The thesis deals with primary dysmenorrhea (PD) in relation to the locomotor system. The aim of the the sis was to compare the frequency of selected joint blocks and the incidence of constitutional hypermobility in PD patients in comparison with the control group. The patient group included 9 women with PD symptoms and the control group consisted of 10 women without these symptoms. The incidence of atlanto - occipital joint block within the patient group was significantly higher than within the control group (p < 0,05). The total number of stuck ribs was also considerably higher in PD patients (p < 0,01). Pain on palpation on the top of the coccygeum apex was significantly higher within the patient group (p < 0,001). Patients with PD did not show significantly different results in Beighton score test for constitutional hypermobility assessment when compared with the control group. Another aim of the thesis was to judge the effect of physical therapy on PD symptoms. For three months, the group of 9 patients had been encouraged to do regular exercises with the impact on postural stability and diagnosed functional disorders of the locomotor system by means of physical therapy. As was shown after the therapy, the reduction of the total number of stuck ribs was statistically significant (p < 0,001). Furthermore,...

Master of Science / Department of Architectural Engineering and Construction Science / Bill Zhang / Vibration has been a consideration in many types of structures, and as the advancement of technology has allowed steel and concrete sections to become lighter, vibration has become more of a consideration in the design of structures. This report focuses on occupant induced vibration of steel framed floors due to running as the vibration source. The history of vibration analysis and criteria in structures is discussed. However, lack of research and experimentation on running as the source of vibration exists; therefore, the history section focuses on walking as the source of vibration. The current design criteria for vibration of steel framed floors in the United States of America is the American Institute of Steel Construction (AISC) Design Guide 11: Vibrations of Steel Framed Structural Systems Due to Human Activity. This design guide discusses vibration due to walking, running, and rhythmic activities as well as gives design criteria for sensitive occupancies and sensitive equipment. In order to apply the Design Guide 11 analysis procedure for running as the source of vibration, the Kansas State University Chester E. Peters Recreation Complex is used as a case study. The recreation complex includes a 1/5-mile running track that is supported by a composite steel framed floor. Based on the Design Guide 11 criterion, the running track is deemed acceptable. Lastly, this report discusses remedial procedures in the case of annoying floor vibration specific to floors that have running as a source of vibration. In addition, areas of further research are suggested where running is a source of vibration on steel framed floors.

Title: Dysmenorrhea and its possible treatment by physiotherapy Objectives: The aim of this thesis has been to assess the effect of simple feet exercises along with the practice of pelvic floor activation and relaxation on women struggling with dysmenorrhea. Subsequently, it also deals with the issue of whether the pelvic floor treat- ment per rectum together with the exercises is more effective than just plain exercising. Methods: This research has been based on an experiment. This thesis includes both a the- oretical part and a practical part. The methods used for the practical part are as follows: questionnaire (specifically Menstrual Symptom Questionnaire), simple feet exercises, ex- ercises used for the activation and relaxation of the pelvic floor as well as the pelvic floor treatment per rectum and final processing of the gathered data into statistics. Results: The menstrual cycle of every woman is completely individual and every woman perceives it quite differently. The result of the research was that simple feet exercises along with the practice of pelvic floor activation, relaxation and the pelvic floor treatment per rectum help women struggling with dysmenorrhea. We didn't discover any data that confirms whether the pelvic floor treatment per rectum, together with the exercises, is more...

Thesis advisor: Katherine Hutchinson / Lower urinary tract (LUTS) storage symptoms, including overactive bladder (OAB) and urinary incontinence (UI), are common conditions among women with significant health and economic consequences. Much of the existing literature on LUTS focuses on older, often postmenopausal women, and there is limited research available about prevalence, incidence and severity of LUTS in young women. For many young women in the United States, the period from the late teens through early twenties coincides with the period of emerging adulthood and college enrollment. The unique factors influencing women at this stage of development may be influential in understanding prevalence and correlates of OAB and UI later in the life-course. The purpose of this cross-sectional descriptive survey-based study was to explore and describe the experience of urinary storage symptoms, specifically OAB and UI, among female undergraduate college students, and to identify associated factors. Qualtrics online platform was used to create and distribute the survey to a sample of 1,800 female college undergraduate students at a private Catholic university in the northeast. Two instruments previously used to assess LUTS, the ICIQ-FLUTS and LUTS Tool, were combined into the Urinary Symptoms Scale with a one-week recall. Twelve items assessed LUTS storage symptoms of OAB and UI. The final sample consisted of 456 female undergraduate college students with a mean age of 20.3-years-old. The sample was predominantly White non-Hispanic. Most commonly reported symptoms included urgency (47.6%), frequency (52.6%), urinary incontinence (21.3%), stress urinary incontinence (28.8%), and urge urinary incontinence (16.4%). Total severity scores were low and highly skewed towards the lower range (M = 3.31; SD = 3.91). Participants with symptoms, most commonly reported experiencing symptoms rarely or sometimes during the past week. Perceived bother from urinary symptoms mean scores were low (M = 1.77) but extended the full range on a 0 to 10 scale. In this study, perceived bother from urinary symptoms as well as perceived impact of urinary symptoms on activities of daily life (ADLs) were significantly associated with care-seeking and use of self-management strategies. Interestingly, LUTS storage symptom severity was not significantly associated with care-seeking, but it was related to use of self-management strategies in this population. Perception of overall health, history of constipation/IBS, sexual activity, delayed toileting behaviors, and premature toileting behaviors were significant in multivariate analyses when controlling for other factors. Further research on the relationship of these factors and LUTS storage symptoms is needed. This study represented a first step in understanding college women’s experiences with LUTS storage symptoms and identifying the unique personal, behavioral and environmental factors associated with LUTS. The study found that OAB and UI symptoms are common among female college undergraduates. In addition, a number of personal and behavioral factors were found to be associated with LUTS storage symptoms. Given that many health-related behaviors established during college years may persist later in adulthood, identifying experiences and influences of young women’s LUTS storage symptoms is important in informing future research and practice recommendations. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

A capacidade de contração dos músculos do assoalho pélvico (MAP) está diretamente relacionada a viabilidade de realizar o seu treinamento. A literatura até hoje não traz informações a respeito da capacidade das mulheres estimarem sua própria contração dos músculos do assoalho pélvico. Os objetivos deste estudo foram avaliar a auto-percepção de mulheres da contração dos MAP e de sua intensidade, os relatos de sintomas de disfunções dos MAP, e avaliar a correlação entre os relatos de sintomas de disfunção dos MAP e a auto-percepção da contração muscular. Trata-se de um estudo observacional transversal conduzido no Centro de Saúde Escola Dr. Joel Domingos Machado de agosto de 2016 a abril de 2018. Foram recrutadas mulheres residentes em Ribeirão Preto com idades acima de 18 anos. A escala de Oxford modificada (EOM) foi utilizada como medida de desfecho para avaliar a percepção da contração dos MAP pelas mulheres. Uma avaliadora cega em relação a percepção da contração pelas participantes realizou o exame da função dos MAP utilizando o mesmo instrumento. Os sintomas de disfunção dos MAP foram avaliados por meio dos questionários validados International Consultation on Incontinence Questionnaire on Urinary- Short Form (ICIQ-SF), Pelvic Organ Prolaps/ Urinary Incontinence Sexual Questionnaire (PISQ-12), Pelvic Organ Prolaps Impact Questionnaire (PFIQ-7) e Pelvic Organ Prolaps Distress Inventory (PFDI- 20). Os seguintes testes foram utilizados na análise estatística: coeficiente de correlação de concordância de kappa ponderado, o coeficiente de correlação de Pearson e o teste exato de Fisher. As análises estatísticas foram realizadas utilizando o software estatístico SPSS 22. Os valores de p<=0,05 foram considerados estatisticamente significativos. Foram recrutadas 163 mulheres da cidade de Ribeirão Preto, destas 81 não comparecem para avaliação e 82 foram incluídas na pesquisa. A média de idade das mulheres foi de 46,83 (±17,94), 34 (41,5%) eram casadas, 59 (71,9%) brancas, 38 (46,4%) com 8 á 11 anos de escolaridade, multíparas com uma média de 2,17 gestações, 45 (54,9%) não apresentavam sintomas de IU e 77 (93,9%) nunca realizaram o treinamento dos MAP. As mulheres apresentaram uma baixa auto-percepção de contração dos MAP, somente 33% acertou corretamente a intensidade da sua contração. A avaliação da contração dos MAP por meio da palpação vaginal não apresentou uma concordância mínima com a auto percepção(p=0,087/?=0,139). A auto-percepção não apresentou correlação com os sintomas de disfunções através dos questionários PFDI-20, PFIQ-7, ICIQ-SF e PISQ-12. A avaliação da contração muscular apresentou uma correlação fraca negativa com o questionário PFDI-20 nos domínios IU (rs=-0,315/p=0,004), POP (rs=-0,330/p=0,002) e escore total (rs=0,387/p=0,000), uma correlação fraca negativa com o questionário PFIQ-7 nos domínios IU (rs=-0,320/p=0,003), POP (rs=-0,244/p=0,027) e escore total (rs=- 0,329/p=0,003). Uma correlação fraca positiva com o questionário de função sexual PISQ-12 (rs=0,360/p=0,008) e uma correlação negativa moderada com o questionário ICIQ-SF de sintomas de incontinência urinária (rs=-0,406/p=0,000). Concluiu-se que as mulheres dessa amostra apresentaram uma baixa auto-percepção da contração dos MAP, somente 33% estimou corretamente a sua contração muscular. / The ability to perform a pelvic floor muscles (PFM) contraction is directly related to the feasibility of performing their training. To date the literature does not provide information regarding to women\'s ability to estimate their own PFM contraction. This study aims to assess women\'s self-perception of PFM contraction and its intensity, the prevalence of PFM dysfunction symptoms, and to analyse the relation between these symptoms and self-perception of muscle contraction. This is a cross-sectional observational study conducted at Dr. Joel Domingos Machado School Health Center from August, 2016 to April, 2018. Women living in Ribeirão Preto aged above 18 years were recruited. The modified Oxford scale was used as an outcome measure to assess women\'s perception of PFM contraction. A blind evaluator regarding to women\'s self-perception of PFM contraction assessed PFM function using vaginal palpation to classify it with same instrument. PFM dysfunction symptoms were assessed using the following validated questionnaires International Consultation on Incontinence Questionnaire on Urinary- Short Form (ICIQ-SF), Pelvic Organ Prolaps/ Urinary Incontinence Sexual Questionnaire (PISQ-12), Pelvic Organ Prolaps Impact Questionnaire (PFIQ-7) e Pelvic Organ Prolaps Distress Inventory (PFDI-20). Weighted kappa concordance correlation coefficient, Pearson\'s correlation coefficient and Fisher\'s exact test were used in the statistical analysis. SPSS 22 statistical software was used and values of p<=0.05 were considered statistically significant. A total of 163 women were recruited, 81 did not attend for evaluation and 82 were included in the study. The mean age of the participants was 46.83 (± 17.94), 34 (41.5%) were married, 59 (71.9%) were white, 38 (46.4%) have from 8 to 11 years of formal education. Most of them were multiparous with an average of 2.17 pregnancies, 45 (54.9%) had no symptoms of urinary incontinence, and 77 (93.9%) had never performed PFM training. The participants had a low self-perception of PFM contraction, only 33% hit correctly the intensity of their contraction. PFM contraction assessed by vaginal palpation did not show a minimum agreement with self-perception (p = 0.087/ ?= 0,139). Self-perception did not correlate with dysfunctions symptoms evaluated by the questionnaires PFDI-20, PFIQ-7, ICIQ-SF and PISQ-12. The PFMfunction presented a weak negative correlation with the PFDI-20 questionnaire in the domains of UI symptoms (rs = -0.315 / p = 0.004), POP (rs = -0.330 / p = 0.002) and total score (rs = 0.387 / p = 0.0002), with PFIQ-7 questionnaire in the IU domains (rs = -0.320 / p = 0.003), POP (rs = -0.224 / p = 0.027) and total score 0.003). A weak positive correlation was found between self-perception and PISQ-12 questionnaire (rs = 0.360 / p = 0.008) and a moderate negative correlation with the ICIQ-SF (rs = -0.406 / p = 0.000). In conclusion women of this sample had a low self-perception of PFM contraction, only 33% correctly estimated their muscle contraction.
