A curvilinear regression model was used to determine an expected stomach capacity for any size Bear Lake sculpin with a standard length between 4-9.5 centimeters. Stomach contents were then expressed as a percent fullness and the change in percent fullness with time intervals was used to compute an instantaneous digestion rate. The instantaneous consumption rate was computed by the formula C=log P1-log P0 +d, where C=instantaneous consumption rate. The amount of food consumed during a time interval was computed from the formula It=CtSt, where It=amount of food ingested during a time interval expressed in percent fullness of stomach. The 24 hour consumption rate was computed by summing the consumption rates for 4 consecutive time intervals of 6 hours each. Studies in September, December, and May give instantaneous digestion rates of -.424, -.214, and -.235 and total food consumption rates of 22.2, 10.2, and 6.1 percent of stomach capacity for each individual fish in the population.

I believe an individual can be profiled by their color preferences, but not indefinitely, for a shorter period of time, a 24-hour period of time. A person's state of mind will change continually based on their experiences. These experiences will affect their perception and preference of color. I developed a model that will map an individual's profile, a portrait, through color. Participants are given a worksheet and a list of terms describing personality traits and states of mind. The worksheet is categorized by event, time of day, duration, impact, and summed term. From midnight to midnight, a 24-hour period, the participant records any event that they encounter providing information-fulfilling categories stated above. I use that information to then map out their portrait of 24-hours through color.

Objetivos: Avaliar a associação entre a dismotilidade esofágica, caracterizada como Motilidade Esofágica Ineficaz (MEI), com a presença de refluxo ácido patológico avaliado pela pH-metria de 24 horas, controlando por Esfíncter Esofágico Inferior (EEI) estruturalmente defeituoso, Hérnia Hiatal (HH) e Esofagite, em pacientes em investigação de Doença do Refluxo Gastroesofágico. Métodos: Foram estudados 311 pacientes referenciados para investigação de DRGE em laboratório de motilidade esofágica. Os pacientes foram submetidos à Endoscopia Digestiva Alta (EDA), Manometria Esofágica, pHmetria Esofágica de 24 horas e a uma entrevista sobre os sintomas clínicos apresentados. Foram comparados os grupos de pH-metria negativa com o de pH-metria positiva quanto à presença dos fatores de risco – MEI, EEI defeituoso, HH e Esofagite. A associação entre MEI e pH-metria positiva foi primeiramente avaliada através de análise univariada e, posteriormente, através de análise de regressão logística (multivariada). Resultados: Do total de 311 pacientes estudados, 208 preencheram os critérios de inclusão. A idade média foi 47 anos, com 88 pacientes apresentando pH-metria normal e 120 pH-metria positiva. Após a análise univariada, foi observado que a ocorrência de MEI, EEI defeituoso e HH foi significativamente maior no grupo de pH-metria positiva. Após análise de regressão logística, a ocorrência de MEI e EEI defeituoso permaneceram significativamente maior no grupo de pH-metria positiva. Conclusões: MEI está associada à presença de refluxo ácido anormal, avaliado através de pH-metria esofágica de 24 horas, independentemente da presença de EEI defeituoso, HH ou Esofagite. / Objectives: To assess the association between esophageal dysmotility, characterized as inefficient esophageal motility (IEM), and the presence of pathological acid reflux due to a structurally defective lower esophageal sphincter (LES), hiatus hernia (HH), or esophagitis in patients suspected of having gastroesophageal Reflux reflux disease (GERD). Methods: Three hundred and eleven patients referred for GERD diagnostic procedures in a gastroesopahgeal motility laboratory were included in the study. Patients underwent upper endoscopy (UE), esophageal manometry, 24-hour esophageal pH-metry and an interview regarding their clinical symptoms. The following risk factors of patients in the negative pH-metry group were compared to those in the positive pH-metry group: IEM, defective LES, HH, and esophagitis. The association between IEM and positive pH-metry results was first assessed by means of univariate analysis and later determined with logistic regression analysis (multivariate). Results: Of the total 311 patients studied, 208 met the inclusion criteria (mean age 47 years); 88 had normal pH-metry reslults and 120 had positive pH-metry results. Univariate analysis revealed that the occurrence of IEM, defective LES, and HH was significantly greater in the positive pH-metry group. Following logistic regression analysis, the occurrence of IEM remained significantly greater in the positive pH-metry group. Conclusions: IEM is associated with the presence of abnormal acid reflux, as assessed by 24-hour esophageal pH-metry, regardless of the presence of defective LES, HH, or esophagitis.

Over the last few decades there has been a gradual transformation in both the spatial and temporal patterns of urban activities. The percentage share of non-discretionary travel such as morning rush-hour commuting has been declining with the increased income level. Discretionary activities appear to rise prominently in urban business and leisure hubs, attracting large volumes of crowds which in turn imply new and changed demand for building floorspace and urban infrastructure. Despite impressive advances in the theories and models of infrastructure demand forecasting, there appear to be an apparent research gap in addressing the practical needs of infrastructure planning in and around those growing urban activity hubs. First, land use and transport interaction models which have to date been the mainstay of practical policy analytics tend to focus on non-discretionary activities such as rush-hour commuting. Secondly, the emerging activity based models, while providing significant new insights into personal, familial activities, especially the discretionary travel, are so data hungry and computing intensive that they have not yet found their roles in practical policy applications. This dissertation builds on the insights from above schools of modelling to develop a new approach that addresses the infrastructure planning needs of the growing urban hubs while keeping the data and computing realistic in medium to high income cities. The new model is designed based on an overarching hypothesis that considerable efficiency and welfare gains can be achieved in the planning and development of urban business and leisure hubs if the infrastructure provisions for discretionary and non-discretionary activities can be coordinated. This is a research theme that has been little explored in current literature. The new infrastructure demand forecasting model has been designed with regard to the above hypothesis and realistic data availability, including those emerging online. The model extends the framework of land use transport interaction models and aim to provide a practical modelling tool. Land use changes are accounted for when testing new infrastructure investment initiatives and especially the road and public transport loads are assessed throughout all time periods of a working day. The new contribution to the modelling methodology includes the extension to the land use transport interaction framework, the use of social media data for estimating night market activity distribution and a rapid estimation of road traffic speeds from Google directions API, and model validation. Another new contribution is the understanding of the nature and magnitude of future infrastructure demand through assessing three alternative land use scenarios: (1) business as usual, (2) inner city regeneration for a major business hub around the night market, and (3) dispersed suburban growth with distant subcentres. The model is able to assess the implications for future infrastructure demand and user welfare through discerning the distinct discretionary and non-discretionary activity patterns.

With the rise of the millennial generation, a new roster of cities has sprung to life – the 18-hour cities. They can be defined as a vibrant second-tier city where there’s a big potential for employment and economic growth and at the same time they offer a lower cost of living and doing business than in 24-hour gateway cities like New York City or San Francisco. They have been named the hottest places for real estate investments by industry literature which poses the question if 18-hour cities really offer better investments than 24-hour cities. This paper uses a statistical analysis framework complemented with qualitative interviews of industry professionals based in 18-hour markets to test this notion. From the statistical analysis, it has been found that 18-hour cities offer higher yields than the 24-hour markets but the cash return cannot be said do differ between the two. Furthermore, the interviews with industry professionals indicate that the 18-hour markets have major future growth prospects because of their job growth, population growth and the large in-migration of high-skilled labor gravitating towards these amenity-rich areas where they can receive the highest reward-for-skill / Med millenniegenerationens framfart har en ny rad städer vaknat till liv – 18-timmarsstäderna. De kan definieras som en levande andrastad där det finns stor potential för arbete och ekonomisk tillväxt samtidigt som de erbjuder lägre levnadskostnad och kostnad för att driva företag än 24-timmarsstäder som New York eller San Francisco. De har utsetts till de hetaste marknaderna för fastighetsinvesteringar av tidsskrifter vilket väcker frågan om 18-timmarsstäder verkligen erbjuder bättre investeringsmöjligheter än 24-timmarsstäder. Denna studie använder statistisk analys kompletterat med intervjuer av personer verksamma i fastighetsbranschen för att testa den hypotesen. Från den statistiska analysen fanns det att 18-timmarsstäder erbjuder högre direktavkastning än 24-timmarsstäder men avkastningen på kapital kan inte säga skiljas mellan de två klustren. Vidare indikerade intervjuerna med branschfolk att 18-timmarsstäder har stor framtida tillväxtpotential tack vare stark jobbtillväxt, befolkningsökning och stor inflyttning av högutbildad arbetskraft som drar sig till områden med mycket bekvämligheter och där de kan få bäst belöning för sin utbildningsnivå.

Majstorović, Z. Utsöndring av stenbildande substanser i urin – kan stickprov er-sätta dygnsmängder? Examensarbete i Biomedicinsk laboratorievetenskap 15 högskolepoäng. Malmö högskola: Hälsa och samhälle, Utbildningsområde Bio-medicinsk laboratorievetenskap, 2011.Syfte. Utredning av njurstenspatienter omfattar alltid undersökning av utsönd-ringen av stenbildande substanser i urin. Samlingen av urin under ett dygn hos njurstenpatienter innebär ofta problem för patienten eftersom det inte är så sällan att de glömmer samla urin i dunken eller samlar för lång eller kort tid. Syftet med min undersökning är att undersöka om det finns alternativ till att samla urin under 24 timmar i de fall där utsöndringen av stenbildande substanser är konstant över dygnet. Frågeställningen är om utsöndringen av stenbildande substanser kan upp-skattas genom att relatera deras koncentration i urin till koncentrationen av kreati-nin i urin eftersom utsöndringen av kreatinin är relativt konstant över dygnet. I så fall bör koncentrationen av stenbildande substanser i urin kunna relateras till kon-centrationen av kreatinin i urin på samma sätt som vid narkotikaanalys. Metod. Försökspersonerna samlade all urin i exakt 24 timmar. Den första urinportionen sparades i ett separat kärl medan all efterföljande urin samlades i en separat dunk . Efter ca en vecka gjordes en ny urinsamling, denna gång bara i en dunk. Dygnsut-söndringarna jämfördes med varandra och med kreatininindex i stickprovet. Re-sultat. Ett starkt samband fanns mellan kreatininindex av kalcium och dygnut-söndringen av kalcium. Sambandet var något mindre starkt för magnesium och saknades för fosfat och kalium. Slutsats. Resultaten talar mot att kreatininindex generellt kan användas för att skatta utsöndringen av njurstensbildande substanser. Däremot verkar kreatininindex relativt väl förutsäga utsöndringen av kalcium och i viss mån även magnesium. / Majstorović, Z. Secretion of stone-forming substances in the urine - can spot urine sample replace 24 hour urine collection? Degree project in Biomedical Laboratory Science, 15 credits points. Malmö University, Health and Society, Department of Biomedical Laboratory Science, 2011.Objective. Clinical investigation of kidney stone patients always includes moni-toring of the secretion of stone-forming substances in the urine. However, 24 h urine collection is difficult for the patient and prone to error. The purpose of this study is to examine whether there are alternatives to the collecting of urine under the period of 24 hours in cases where the secretion of stone-forming substances is constant across days. The question is whether the excretion of stone-forming sub-stances can be estimated by relating the concentration of urine to the creatinine concentration of urine, since the excretion of creatinine is relatively constant over a day. If so, the concentration of stone-forming substances in urine could be relat-ed to the concentration of creatinine in urine in the same way as drug analyses commonly are. Method. The subjects collected a 24h collection of urine. The first urine portion was stored in a container, while all subsequent urine was collected in a separate container. After about a week, another timed collection of urine was performed, but this time only in one container. The 24 h solute excretions were compared to each other and to the solute creatinine index. Results. A strong cor-relation was found between the creatinine index of calcium and the 24 h excretion of calcium. A somewhat weaker correlation was found for magnesium and a lack of correlation for phosphate and potassium. Conclusion. Results indicate that creatinine indexes in general do not predict 24 h excretions. However, creatinine index appears to predict the excretion of calcium and, to some extent, magnesium.

Introduction: Plusieurs indices de qualité alimentaire globale ont été élaborés en misant sur la consommation de certains nutriments ou aliments, ou des groupes d’aliments. Les indices de la qualité alimentaire globale sont en mesure d’évaluer de manière intégrée les aspects recherchés d’une bonne alimentation. C’est dans ce cadre que le Canadian Healthy Eating Index (C-HEI) a été développé pour évaluer le degré auquel les apports alimentaires des individus rencontrent les consignes du guide alimentaire canadien et les Recommandations nutritionnelles canadiennes. Objectif: Evaluer les liens entre l’indice de la qualité alimentaire globale C-HEI calculé à partir de la moyenne de trois rappels alimentaires de 24 heures et des paramètres nutritionnels, anthropométriques et des indicateurs de santé au recrutement (T1) dans l’étude longitudinale québécoise sur la nutrition et le vieillissement réussi (NuAge). Méthodologie: Des analyses bivariées (coefficients de corrélation, tableaux croisés et la statistique khi deux) ont été réalisées afin de déterminer les associations entre le score total C-HEI et certaines variables nutritionnelles, anthropométriques et le nombre de maladies chroniques. Résultats et discussion: Les participants ont rencontré ou dépassé la plupart de leurs apports nutritionnels de référence. Le C-HEI n’a pas été fortement corrélé aux nutriments individuels (rs= 0,14-0,52, p<0,01). Le C-HEI total était significativement associé aux recommandations canadiennes pour l’apport en fibres (rs= 0,51), le % d’énergie provenant des lipides (rs=-0,60) et des acides gras saturés (rs= -0,59), p<0,01. De plus, la suffisance en protéines et en énergie est augmentée lorsqu’on passait du Q1 (plus faible) à Q4 (plus élevé) du C-HEI (p<0,05). De même, les proportions des sujets ayant des mesures anthropométriques associées aux risques accrus pour la santé sont diminuées en passant du Q1 au Q4 (p<0,05), témoignant ainsi des liens entre une alimentation de bonne qualité et la protection des risques de santé associés à l’embonpoint et à l’obésité. Conclusion : Les résultats de cette recherche ont fourni des preuves additionnelles sur le lien entre le score C-HEI et certains paramètres nutritionnels et anthropométriques d’intérêt, et ce, provenant des données alimentaires quantitatives colligées au sein d’une population âgée vivant dans la communauté. / Introduction: Several diet quality indicators have been developed based on nutrient intakes, foods or food groupings, or a combination of nutrient and foods. Measures of overall diet quality consider numerous aspects of dietary intake. It is within this framework that the Canadian Healthy Eating Index (C-HEI) was adapted to Canadian dietary and nutritional guidance using Canada’s Food Guide and Nutrition recommendations for Canadians. Objectives: To determine the links between the C-HEI using the mean of three 24-hour diet recalls, and certain health outcomes at entry into the study (T1). The analyses were carried out using data collected from participants in the Quebec Longitudinal Study on Nutrition and Successful Aging (NuAge). Methodology: Bivariate analyses (Spearman correlation, cross-tabulation and chi-square) were carried out to assess relationships between nutritional and anthropometric variables, the number of chronic disease and the C-HEI. Results and Discussion: Participants met or exceeded most Dietary Reference Intakes (DRI). The C-HEI did not show consistent relationships with individual nutrients (rs= 0.14-0.52, p<0.01). However, selected sub-scores of the C-HEI reflect attainment of Canada’s Food Guide recommendations, showing a strong association with dietary fiber intakes (rs= 0.51) and nutrition recommendations addressing percent energy as fat (rs=-0.60) and as saturated fat (rs= -0.59), p<0.01. Energy and protein adequacy increased from Q1 to Q 4 of C-HEI (p<0.05). In addition, proportions of subjects with anthropometric measures associated with a health risk decreased from quartiles Q1 to Q4 (p<0.05), attesting to links between good diet quality and lower health risks associated with overweight and obesity. Conclusion: The C-HEI discriminates overall diet quality based on dietary data collected from 24HR, providing further evidence on the links between the C-HEI and selected nutritional and anthropometric parameters as applied to quantitative dietary data obtained from community-dwelling older adults.
