Real-time video transmission in UMTS

2001

Masteroppgave i informasjons- og kommunikasjonsteknologi 2001 - Høgskolen i Agder, Grimstad Universal Mobile Telecommunication System is denoted as a 3rd cellular system and has been designed with the objective to be a system with global coverage. With the major improvement of in bandwidth capability the Universal Mobile Telecommunications System will be able to support real time multimedia services. This thesis starts with a presentation of the possible video services that can be exploited in third generation cellular systems. Video services are known to be bandwidth consuming and have rigid requirements to the real time requirements. Though the major increase in available bandwidth in the…

Nelielas tīmekļa lietotnes neformālās izstrādes vadlīnijas

2015

Darba ietvaros, pamatojoties uz tīmekļa lietotņu un to ieviešanas pieeju analīzi, tiek definētas vadlīnijas nelielas tīmekļa lietotnes ieviešanai, izmantojot neformālu pieeju. Balstoties uz definētajām vadlīnijām, kā prototips tiek izstrādāta neliela un nesarežģīta tīmekļa lietotne elektronisko pieprasījumu pārvaldībai, kuras izveides apraksts ir sniegts darbā, tādējādi ilustrējot izstrādāto vadlīniju izmantošanu lietotnes izstrādes procesā. Lai nodrošinātu noteiktu darba mērķu sasniegšanu, darba sākumā ir analizēta tīmekļa lietotņu būtība, īsi apskatīta to vēsture, analizētas tīmekļa lietotņu tehnoloģijas, kā arī iztirzāti tīmekļa lietotņu arhitektūras varianti. Darba turpinājumā ir definē…

Sensory-based food education in early childhood education and care, willingness to choose and eat fruit and vegetables, and the moderating role of ma…

2018

AbstractObjectiveTo investigate the association between sensory-based food education implemented in early childhood education and care (ECEC) centres and children’s willingness to choose and eat vegetables, berries and fruit, and whether the mother’s education level and children’s food neophobia moderate the linkage.DesignThe cross-sectional study involved six ECEC centres that provide sensory-based food education and three reference centres. A snack buffet containing eleven different vegetables, berries and fruit was used to assess children’s willingness to choose and eat the food items. The children’s parents completed the Food Neophobia Scale questionnaire to assess their children’s food…

Identification and characterization of a gene encoding a putative mouse Rho GTPase activating protein gene 8, Arhgap8.

2003

Rho GTPase activating proteins promote the intrinsic GTP hydrolysis activity of Rho family proteins. We isolated a putative mouse ortholog of the human Rho GTPase activating protein 8, ARHGAP8. The open reading frame encodes a peptide of 387 amino acids with high homology to human ARHGAP8 in its N-terminal domain. Both radiation hybrid mapping and fluorescent in situ hybridization localized the gene to mouse chromosome 15E. The 23 kb genomic Arhgap8 sequence consists of eight exons and seven introns. Northern blot and RT-PCR analyses showed that a transcript of approximately 1.9 kb is ubiquitously expressed in various adult mouse tissues with particularly strong expression in kidney.

Infant and childhood growth and frailty in old age : the Helsinki Birth Cohort Study

2018

BackgroundEvidence from life course studies highlights the importance of infant and childhood growth as risk factors for adulthood chronic diseases.MethodsIn this sub-study of the Helsinki Birth Cohort Study, we studied 1078 individuals who had both information on body size from birth to 12 years of age and who were assessed for frailty according to the Fried criteria at the mean age of 71 years.ResultsGreater BMI gain between 2 and 11 years in boys was associated with frailty in old age (age-adjusted RRR 2.36, 95% CI 1.21, 4.63). No similar associations were observed in girls.ConclusionsMen who were frail in old age experienced accelerated BMI gain in childhood compared with those men who …

Breizacanthus aznari sp. n. (Acanthocephala: Arhythmacanthidae) from the banded cusk-eel Raneya brasiliensis (Ophidiiformes: Ophidiidae) from the Pat…

2012

Breizacanthus aznari sp. n. is described from the banded cusk-eel Raneya brasiliensis (Kaup) (Ophidiiformes: Ophidiidae) from the Patagonian coast in Argentina. Breizacanthus Golvan, 1969 is currently composed of five species (including the new species) and is characterised by the absence of trunk spines, a short cylindrical proboscis with two types of hooks and lemnisci longer than the proboscis receptacle. Breizacanthus aznari is clearly distinguished from B. chabaudi Golvan, 1969 by having 12 longitudinal rows of hooks on the proboscis, instead of 16-18. The new species resembles B. golvani Gaevskaya et Shukhgalter, 1984, B. irenae Golvan, 1969, and B. ligur Paggi, Orecchia et Della Seta…

Adjusting for selective non-participation with re-contact data in the FINRISK 2012 survey

2018

Aims: A common objective of epidemiological surveys is to provide population-level estimates of health indicators. Survey results tend to be biased under selective non-participation. One approach to bias reduction is to collect information about non-participants by contacting them again and asking them to fill in a questionnaire. This information is called re-contact data, and it allows to adjust the estimates for non-participation. Methods: We analyse data from the FINRISK 2012 survey, where re-contact data were collected. We assume that the respondents of the re-contact survey are similar to the remaining non-participants with respect to the health given their available background informa…

Early Life Stress and Physical and Psychosocial Functioning in Late Adulthood

2013

Background. Severe stress experienced in early life may have long-term effects on adult physiological and psychological health and well-being. We studied physical and psychosocial functioning in late adulthood in subjects separated temporarily from their parents in childhood during World War II. Methods. The 1803 participants belong to the Helsinki Birth Cohort Study, born 1934–44. Of them, 267 (14.8%) had been evacuated abroad in childhood during WWII and the remaining subjects served as controls. Physical and psychosocial functioning was assessed with the Short Form 36 scale (SF-36) between 2001 and 2004. A test for trends was based on linear regression. All analyses were adjusted for age…

Age, pathogen exposure, but not maternal care shape offspring immunity in an insect with facultative family life.

2016

Background To optimize their resistance against pathogen infection, individuals are expected to find the right balance between investing into the immune system and other life history traits. In vertebrates, several factors were shown to critically affect the direction of this balance, such as the developmental stage of an individual, its current risk of infection and/or its access to external help such as parental care. However, the independent and/or interactive effects of these factors on immunity remain poorly studied in insects. Results Here, we manipulated maternal presence and pathogen exposure in families of the European earwig Forficula auricularia to measure whether and how the sur…
