Limitations of current eldercare monitoring systems leave a need for new solutions. A monitoring system based on a frequency modulated continuous wave ultra-wideband short-range radar is proposed for this application. The complete proposed monitoring system is comprised of four blocks: boundary detection, silhouette capture, human identification, and data transmission. This paper develops the RF front end hardware for the silhouette capture subsystem. System requirements are derived for the silhouette capture subsystem. An architecture for the RF front end is designed, and required individual component specifications are determined. Components are selected off the shelf or custom designed for each socket. Full transmitter and receiver level plans are calculated to ensure expected system performance meets system requirements. A component library and full system schematic is created, PCB layout is completed, and PCB files are generated and sent for fabrication. PCB traces and individual components are characterized over frequency, and methods that improve inadequate performance are documented and discussed.

In the United States, illnesses associated with fresh produce are increasing in frequency.  While contamination risks are present at every aspect of the farm to fork continuum, post-harvest practices holds the potential for cross-contamination of large amounts of product.  Post-harvest contamination risks for hydroponically grown lettuce packaged with intact roots and sold as "living lettuce"" are poorly understood.  In this study, transmission of Salmonella enterica serotype Enteritidis to the roots and leaves of butterhead lettuce was studied when contamination was introduced during typical handling practices.  The effectiveness of random sampling strategies for selection of Salmonella contaminated leaves was assessed by co-inoculating the Salmonella solution with Glo Germ™ and comparing recovery from blacklight selected leaves.  The recovery of Salmonella was improved by only 0.5 log CFU/g when blacklight was used to select Glo Germ™ contaminated leaves (P=0.05). This suggests random leaf selection as described by current FDA protocols is adequate. In addition, this study showed rapid transfer of Salmonella from liquid to the roots and sub-sequentially to the leaves of living lettuce.  Salmonella persisted but did not grow on leaves when stored at 4˚C for 18-days. Storage at 12˚C was associated with 2 log CFU/g increases in Salmonella on roots after 18-days storage (P=0.0002), while 4˚C storage was associated with a decrease of 0.4 log CFU/g Salmonella on roots (P=0.0001). Growth occurred only under temperature abuse conditions.  This reinforces the need for maintaining temperature control and highlights the importance of identifying risks associated with post-harvest handling during hydroponic production and distribution. / Master of Science in Life Sciences

I have designed and built a small home for myself that is movable by a bicycle. The structure is thought to fit in different places such as in a park, on a street or in the nature. I have been living in the structure for a short period of time, trying it out in different places around Stockholm. I want to understand the consequences of living minimal, to get the whole experience from an idea to the final result. What are the the ingredients of a home today beyond the absolute need of protection? / Jag har ritat och byggt en mobil strucktur som är flyttbar med en cykel. Jag har bott i strukturen en period runt om i Stockholm, för att testa hur självständigt det går att bo och på vilka platser det går att bo. Projektet handlar också om hemmet idag, hur kan det fungera och se ut?

The experiences of the past can serve to enrich the knowledge of the present and progression to future generations. As such architecture should be viewed in accordance with literature, music, art and film as a collective depiction of the transition from past ideals to the contemporary values and future aspirations of a living city. Sites of historic importance within the Central Business District (CBD) will be investigated as qualitative research to determine the significance of these sites to current citizens. This will be used to determine the best location and manifestation of an intervention that will create a dialogue between the citizens of today and the urban landscape, encapsulating Pretoria’s history of social transition which indicates heritage as a living time line. / Dissertation (MArch(Prof))--University of Pretoria, 2010. / Architecture / unrestricted

The way in which a city is spatially laid out effects the natural environment of the planet (for example: pollution and the depletion of natural resources) as well as the social environment (the community and daily life) of its residents. Through the exploration of various modern urban planning theories, I will begin to look at some different approaches to urban planning. This document favours the compact city approach which advocates higher densities, mixed use development, public transport and community living. This approach relates to initiatives currently underway in the inner city of Johannesburg. This document is about the exploration of how people live in the city and the issues surrounding housing in the urban context. The proposed architectural project is a housing scheme located in Newtown, Johannesburg. Central concepts include: urban regeneration, inner city living, visual variety in the urban realm, street edge conditions and public to private hierarchies

My work has focused on the Czech Euroindians history of their origin, what it means to be "Euroindian" and how they themselves understand their way of life models. The aim was to find the identity of the Czech Euroindian in modern Czech society. The work deals with the spiritual culture and the implementation of some of the most characteristic of Indian's ceremonies, habits when camping (spring, summer, autumn, winter) as the teepee construction and compliance with the label inside the teepee, cooking, playing the most typical Indian's games, music and singing and other joint events (Pow wow General Assembly, etc.) and their connection with modern life in Czech society. My work is theoretical and empirical. I base it on the method of qualitative research. I use literary sources, Internet resources, personal communication and e-mails with Czech Euroindians and unstructured interviews with Czech Euroindians. Valuable sources of information were also in journals Buffalo wind, Wampum Neskenonu magazine and the Tramp. I also used the method of participant observation in my own field research, which consisted of two two-week stays at summer Euroindians camps near the village Chýlice by Toužim in year 2004 and 2005 and I continued working on my work Metamorphosis Lakota ceremonies from the past to the...

OBJECTIVES: To examine the rates and correlates of depressive symptoms and syndromal depression in people with self-reported heart failure participating in a community study of people aged 70 and older. DESIGN: Cross-sectional. SETTING: Community-based epidemiological study of older people from the continental United States. PARTICIPANTS: Six thousand one hundred twenty-five older people participating in the longitudinal study of Assets and Health Dynamics. Participants had to be born in 1923 or earlier. MEASUREMENTS: The short-form Composite International Diagnostic Interview assessed syndromal depression, and a revised version of the Center for Epidemiologic Studies - Depression scale assessed depressive symptoms. Medical illness was based on self-report. The authors compared the rates of syndromal depression and individual depressive symptoms in people with self-reported heart failure (n = 199) with those in people with other heart conditions (n = 1,856) and with no heart conditions (n = 4,070). RESULTS: Eleven percent of those with heart failure met criteria for syndromal depression, compared with 4.8% of people with other heart conditions and 3.2% of those with no heart conditions. The association between heart failure and depression held even after controlling for disability, reported fatigue and breathlessness, and number of comorbid chronic illnesses. CONCLUSION: Community-living older people with self-reported heart failure were at approximately twice the risk for syndromal depression of the rest of the community. Although fatigue and functional disability were also related to depression in this sample, these variables did not account for the association between syndromal depression and self-reported heart failure.

In the field of travel and tourism, scholars with interest in consumer behavior studies have explored different variables and linked them with the individual's behavior. Variables such as destination image, environmental awareness, service perception, preferences, and motivations for travel are commonly used to understand and predict destination selections and travel behavior. There is also enough evidence to suggest that healthy-living is positively associated with travel behavior. If any, little empirical research has been done to explore and examine the relationship between healthy-living and travel behavior. The guidelines to healthy-living have not been introduced in the literature of travel and tourism. This study is intended to shed some light on this issue and contribute to knowledge in this area. The objective of this study was twofold: (1) to develop a healthy-living attitudinal construct, and (2) examine the relationship between healthy-living behavioral and attitudinal constructs and selected travel behavior variables. Pearson's correlation coefficient analysis was undertaken to test the relationship between healthy-living and travel behavior variables. In addition, using ANOVA, the study examined if there were differences between healthy-living (behavioral and attitudinal) and socio-demographic variables; and by using Tukey's multiple comparison test, significant differences between the different groups were revealed. Finally, multiple regression analysis was undertaken with the objective to find the degree with which healthy-living alone influences travel behavior while socio-demographic variables are constant or controlled for. The overall findings of the study revealed that there seems to be a relationship between a healthy-living lifestyle and the individual travel behavior. However, the direction and strength of this relationship shows variations with respect to different dimensions of the healthy-living construct and selected travel behavior questions. The perceived importance of the interaction between healthy-living behavior and travel also implies that certain habits and practices of individuals may correspond to certain benefits and expectations that are both valued and obtained from travel experiences and at the destination site. Such information combined with demographic information may be of great help in understanding better the behavior of travelers to destinations. This research contributes to lifestyle studies in tourism and sheds further light on the complex nature of travel behavior. / Ph. D.
