Urban Storm-Water Quality Management: Centralized versus Source Control
2010
The continuous growth of urban areas and the increasing public awareness of the environmental impacts of storm water have raised interest on the quality of the receiving water bodies. In the past two decades, many efforts have been directed at improving urban drainage systems by introducing mitigation measures to limit the negative environmental impacts of storm water. These mitigation measures are generally called best management practices (BMPs), sustainable urban drainage systems, or low impact developments, and they include practices such as infiltration and storage tanks that reduce the peak flow and retain some of the polluting materials. Choosing the best mitigation measure is still …
Inmigración Haitiana en Rio Grande del Sur, Brasil: Aspectos Psicosociales, Aculturación, Prejuicio y Calidad de Vida
2019
Resumo Este estudo traça um panorama da imigração haitiana no Rio Grande do Sul, quanto a aspectos psicossociais, perfil sociodemográfico e socioeconômico, orientações aculturativas, preconceito e qualidade de vida. A pesquisa, de delineamento quantitativo transversal, contou com a participação de 67 imigrantes haitianos, com idades entre 19 e 58 anos (M = 33,87; DP = 5,47). A amostra é predominantemente composta por homens (77,6%), com alta escolaridade (M = 10,5; DP = 4,53) e que falam o idioma português (56,7%). A orientação aculturativa mais frequente é a de integração, que é mais presente entre homens, quem acessou o sistema brasileiro de assistência social; os mais jovens, os com maio…
Do mental health and vitality mediate the relationship between perceived control over time and fear of COVID-19? A survey in an Italian sample
2021
Several studies evidenced increased elevated symptomatology levels in anxiety, general stress, depression, and post-traumatic stress related to COVID-19. Real difficulties in the effective control of time that could be responsible for mental health issues and loss of vitality were also reported. Prior literature highlighted how perceived control over time significantly modulates anxiety disorders and promotes psychological well-being. To verify the hypothesis that perceived control over time predicts fear of COVID-19 and mental health and vitality mediate this relationship, we performed an online survey on a sample of 301 subjects (female = 68%; Mage = 22.12, SD = 6.29; age range = 18–57 ye…
QSAR models for tyrosinase inhibitory activity description applying modern statistical classification techniques: A comparative study
2010
Abstract Cluster analysis (CA), Linear and Quadratic Discriminant Analysis (L(Q)DA), Binary Logistic Regression (BLR) and Classification Tree (CT) are applied on two datasets for description of tyrosinase inhibitory activity from molecular structures. The first set included 701 tyrosinase inhibitors (TI) that are used for performance of inhibitory and non-inhibitory activity and the second one is for potency estimation of active compounds. 2D TOMOCOMD-CARDD atom-based quadratic indices are computed as molecular descriptors. CA is used to “rational” design of training (TS) and prediction set (PS) but it shows of not being adequate as classification technique. On the first data, the overall a…
Cross-cultural adaptation and validation of the French version of the Knee injury and Osteoarthritis Outcome Score (KOOS) in knee osteoarthritis pati…
2008
Udgivelsesdato: 2008-Apr OBJECTIVE: To adapt the Knee injury and Osteoarthritis Outcome Score (KOOS) into French and to evaluate the psychometric properties of this new version. METHODS: The French version of the KOOS was developed according to cross-cultural guidelines by using the "translation-back translation" method to ensure content validity. KOOS data were then obtained in patients with symptomatic knee osteoarthritis (OA). The translated questionnaire was evaluated in two knee OA population groups, one with no indication for joint replacement (medicine), and the other waiting for joint replacement (surgery). The psychometric properties evaluated were feasibility: percentage of respon…
18F-PSMA-1007 ražošana, kvalitātes kontrole un tā salīdzinājums ar citiem radiofarmaceitiskajiem preparātiem
2020
Literatūras apskatā apkopota informācija par radionuklīdiem, radioaktīvo sabrukšanu, pozitronu emisijas tomogrāfiju, prostatas vēzi, radiofarmaceitisko preparātu būtību, nozīmi un kvalitātes kontroli. Tāpat ir apkopota informācija arī par konkrēto radiofarmaceitisko preparātu – 18F-PSMA-1007 un tā sintēzi, kā arī izmantošanas iespējām medicīnā. Maģistra darba eksperimentālajā daļā veikta 18F radionuklīda iegūšana un radiofarmaceitiskā preparāta 18F-PSMA-1007 sintēze, izstrādātas kvalitātes kontroles analīzes metodes, ar kurām tika noteikta radiofarmaceitiskā preparāta radionuklīdu, radioķīmiskās un ķīmiskās tīrības pārbaude, veikta identitātes pierādīšana un noteikti citi kvalitātes paramet…
A tRNA half modulates translation as stress response in Trypanosoma brucei
2019
In the absence of extensive transcription control mechanisms the pathogenic parasite Trypanosoma brucei crucially depends on translation regulation to orchestrate gene expression. However, molecular insight into regulating protein biosynthesis is sparse. Here we analyze the small non-coding RNA (ncRNA) interactome of ribosomes in T. brucei during different growth conditions and life stages. Ribosome-associated ncRNAs have recently been recognized as unprecedented regulators of ribosome functions. Our data show that the tRNAThr 3´half is produced during nutrient deprivation and becomes one of the most abundant tRNA-derived RNA fragments (tdRs). tRNAThr halves associate with ribosomes and pol…
Implementation of Universal Digital Architecture using 3D-NoC for Mobile Terminal
2014
International Conference on Control, Decision and Information Technologies (CoDIT), Ecole Natl Ingenieurs Metz, Metz, FRANCE, NOV 03-05, 2014; International audience; The need to integrate multiple wireless communication protocols into a single low-cost flexible hardware platform is prompted by the increasing number of emerging communication protocols and applications in modern embedded systems. So the current challenge is to design of new digital architectures, in addition to its ability to take over of many functions. In this paper we have identified similarities between the despreader units in Rake receiver and the processor element in FFT-SDF (Fast Fourier Transform-Single path Delay Fe…

GENETIC AND ENVIRONMENTAL VARIATION IN PERCEIVED EXERTION AND HEART RATE DURING BICYCLE ERGOMETER WORK
1977
The relative contributions of heredity and environment to the variance in heart rate (HR) and rating of perceived exertion (RPE) during the bicycle ergometer work were studied with 14 pairs of male (6 monozygous (MZ) and 8 dizygous (DZ)) and 22 pairs of female (8 MZ and 14 DZ) twins ranging in age from 11 to 20 years. The results showed for both sexes that no significant differences in the intrapair variances of HR and RPE could be observed between the MZ and DZ twin samples. Thus it was concluded that in contrast to several other parameters of the measurements of the physical work capacity HR and RPE are not influenced to any significant degree by the genetic factors.
