The Hopeless and the Ict Transformation

2018

Nothing is better than attempting to transform people by boosting their knowledge and improve their living conditions. In Africa and especially in Togo, Elderly people, Artist Painters and Fishermen even though they would like to contribute to their country’s development by their everyday hard-work, are not emerging. Government is not helping and their activities lack efficiency, proper management and appropriate internal communication and with the external world. This is the reason why the ICT in particular People.net, the knowledge charity infrastructure’s potential are proposed as a solution. Communities and various economic sectors could then reinforce their capacity by acquiring the pr…

Granger causality analysis of sleep brain-heart interactions

2014

We studied the networks of Granger causality (GC) between the time series of cardiac vagal autonomic activity and brain wave activities, measured respectively as the normalized high frequency (HF) component of heart rate variability and EEG power in the δ, θ, α, σ, β bands, computed in 10 healthy subjects during sleep. GC analysis was performed by vector autoregressive modeling, and significance of each link in the network was assessed using F-statistics. The whole-night analysis revealed the existence of a fully connected network of brain-heart and brain-brain interactions, with the ß EEG power acting as a hub which conveys the largest number of GC links between the heart and brain n…

ChemInform Abstract: Recyclable Heterogeneous Palladium Catalysts in Pure Water: Sustainable Developments in Suzuki, Heck, Sonogashira and Tsuji-Tros…

2010

This review summarizes the progress made essentially these last ten years on heterogeneous palladium catalysis in pure water. The work covers four important palladium-catalyzed transformations for carbon-carbon bond formation: Suzuki, Heck, Sonogashira and Tsuji-Trost reactions. The discussion focuses on the efficiency and reusability of the heterogeneous catalysts as well as on the experimental conditions from a sustainable chemistry point of view. The review is introduced by a discussion on mechanistic aspects inherent to heterogeneous catalysis.

Assessment of the BMI, WHR and W/Ht in pre- and postmenopausal women

2007

The main goal of this study was to determine whether and how values of the BMI, WHR and W/Ht indicators change in pre- and postmenopausal women. The tested group consisted of 10,216 women aged 25-95 years. Data were collected during the national campaign "Fighting Obesity", organized by Hand-Prod Company between 2000-2002 across Poland, when adult women voluntarily filled in a questionnaire and participated in anthropometric measurements. The BMI, WHR and W/Ht values were calculated based on these measurements. The values of the BMI, WHR and W/Ht change with age. However, in each age group postmenopausal women have higher BMI, WHR and W/Ht than premenopausal women. Thus, the results obtaine…

Sonographic size of uterus and ovaries in pre- and postmenopausal women

1996

Uterine and ovarian size were measured in 765 pre- and postmenopausal women by transvaginal ultrasound. Of these, 263 (premenopausal, n = 155; postmenopausal, n = 108) were found to have neither uterine nor ovarian pathological findings. According to parity, premenopausal women were separated into three groups: nullipara, primipara and multipara. Postmenopausal women were separated into two groups according to years since menopause: 5 years since menopause. In the premenopausal group, a parity-related enlargement in uterine size was observed between nulliparous and parous women. After the menopause, a significant reduction in uterine size and in the corpus-cervix ratio was observed. The red…

Evaluation of different transvaginal sonographic diagnostic parameters in women with postmenopausal bleeding

1998

Objective To determine whether the accuracy of transvaginal sonography to detect endometrial pathology is enhanced by assessing endometrial morphology and the regularity of the endometrial border in addition to measurement of endometrial thickness in women with postmenopausal bleeding. Design and methods A total of 159 women with post-menopausal bleeding were included in a prospective study performed at the Clinic of Obstetrics and Gynecology, University of Mainz. The results obtained on transvaginal sonographic assessment of the endometrium were compared with the histological evaluation of the operative endometrial specimen. Results A cut-off level for endometrial thickness of 5 mm had a s…

Kirja-arvostelut alustataloudessa – esimerkkinä käyttäjälähtöiset arvostelut Instagramissa

2021

Kulttuurituotteita eivät sosiaalisen median aikakaudella enää arvostele julkisesti vain perinteisen median ammattikriitikot, vaan myös tavalliset ihmiset osallistuvat teosten julkiseen arvottamiseen erilaisilla digitaalisilla alustoilla. Tarkastelemme tässä artikkelissa kirjallisuusarvosteluja osana alustoitunutta kulttuurituotantoa esimerkkinämme käyttäjälähtöiset kirja-arvostelut erityisesti kuvasovellus Instagramissa. Instagramiin on vakiintunut kirjallisuuskeskusteluyhteisö, jota kutsutaan maailmanlaajuisesti nimellä Bookstagram mutta jolla on myös paikallisia tai alueellisia muotoja, kuten suomalainen Kirjagram. Kysymme, miten käyttäjäarvostelijat esiintyvät niissä arvostelulle määrite…

Dihidropirimidīnu sintēze un pielietojums vīrusu kapsīdu inhibēšanai un pincera kompleksu iegūšanai

2018

Sīpola A., darba vadītāja Dr. chem. Vīgante B. Maģistra darbs organiskajā ķīmijā, 67 lappuses, 45 attēli, 11 tabulas, 85 literatūras avoti, 21 pielikums. Latviešu valodā. Darbā sintezēti jauni heteroarildihidropirimidīni. Variējot ar aizvietotājiem, mēģināts piemeklēt atbilstošas savienojumu struktūras, kas spētu ietekmēt vīrusa kapsīdas veidošanos. Daži no sintezētajiem savienojumiem oksidēti un izmantoti jaunu kompleksu veidošanai ar pārejas metāliem. Iegūtie kompleksi tālāk izmantoti kā katalizatori ķīmiskajās reakcijās, tiecoties uz “zaļās ķīmijas” attīstību. Daļa no iegūtajiem rezultātiem ir publicēti konferences tēzēs un plakātā – 3.

Cilvēka herpesvīrusa-6 U12 un U51 gēnu kodēto proteīnu iespējamā loma autoimunitātes attīstībā

2020

HHV-6 ir visuresošs patogēns, kurš spējīgs persistēt saimniekorganismā visu tā dzīvi un kura loma pierādīta vairāku saslimšanu attīstībā, tostarp arī autoimūnu. Lai gan HHV-6 un autoimūno vairogdziedzera slimību saistība parādīta, mehānismi, kas norādītu kā HHV-6 spēj ietekmēt autoimunitātes attīstību, nav noskaidroti. HHV-6 piemīt virkne imūnmodulējošu īpašību, ar kurām vīruss manipulē imunitāti, lai veicinātu tā izplatību pa organismu un izvairītos no saimniekorganisma imūnās atbildes. Šī darba ietvaros tika novērtēta HHV-6 hemokīnu receptoru U12 un U51 loma autoimunitātes attīstībā, izmantojot no vīrusa aminoskābju sekvencēm veidotus potenciāli imunogēnus peptīdus. Peptīdu imunogenitātes…
