Topological canal foliations
2019
Regular canal surfaces of $\mathbb{R}^3$ or $\mathbb{S}^3$ admit foliations by circles: the characteristic circles of the envelope. In order to build a foliation of $\mathbb{S}^3$ with leaves being canal surfaces, one has to relax the condition “canal” a little (“weak canal condition”) in order to accept isolated umbilics. Here, we define a topological condition which generalizes this “weak canal” condition imposed on leaves, and classify the foliations of compact orientable 3-manifolds we can obtain this way.
Gap acceptance analysis in an urban intersection through a video acquired by an UAV
2014
Purpose of this paper is to apply a methodology previously developed to achieve an accurate measurements of the real traffic condition thought the use of a video acquired by an UAV (Unmanned Aerial Vehicle) and a probe vehicle equipped with a differential GPS. The used methodology is not invasive and thus, it doesn't influence the driver behavior. The used equipment must not be compared to the traditional techniques of traffic flow but it can be used for particular situations in which the installation of fixed detectors is not economic. In particular, we have analyzed the gap acceptance for an urban intersection between a main road with dual carriageway and two lanes in one direction, that …
Regularity and modulus of continuity of space-filling curves
2019
We study critical regularity assumptions on space-filling curves that possess certain modulus of continuity. The bounds we obtain are essentially sharp, as demonstrated by an example. peerReviewed
Специфика перевода и лексикографического описания эортологической лексики
2022
Religious vocabulary covers a very wide area and includes numerous thematic blocks. From the lexicographer's point of view, it can be divided into two groups. The first is popular words often used in everyday life, and the second group in this conditional classification covers terminological religious vocabulary of a thematic nature, ranging from purely material, subject, cult concepts, and ending with philosophical and theological concepts. In the context of ongoing research, the author is interested in the specifics of translation and lexicographic description of eortonyms.
Higher Socioeconomic Status Predicts Less Risk of Depression in Adolescence: Serial Mediating Roles of Social Support and Optimism.
2020
Family socioeconomic status (SES) is known to have a powerful influence on adolescent depression. However, the inner mechanisms underlying this association are unclear. Here, we explore this issue by testing the potential mediating roles of social support (interpersonal resource) and optimism (intrapersonal resource), based on the predictions of the Reserve Capacity Model (RCM). Participants were 652 adolescents (age range: 11-20 years old, Mage =14.55 years, SD = 1.82; 338 boys (51.80%)) from two junior and two senior high schools in Wuhan, China. They completed questionnaires measuring family SES, perceived social support, trait optimism, and depression. Results showed, as predicted, (1) …
Oppilaiden kanssa vastuuta jakamassa : peruskoulun kahdeksannen luokan oppilaiden autonomian vahvistaminen englannin oppitunneilla samanaikaisopetuks…

The aim of this ethnographic and autoethnographic research was to explore what kind of a learning culture existed in an 8th grade English class in a Finnish basic education school in the 2011-2012 academic year. The class was taught jointly by a subject teacher and a special education teacher. A teaching experiment was implemented with the support of co-teaching during which teachers aimed to strengthen students' learning autonomy: to support their active learning and help them act as responsible learners. The research data included participant observation notes, interviews of a subject teacher and students, and different kinds of documents produced by teachers and students during the imple…
Low levels of both xanthine dehydrogenase and of cellular retinol binding protein are responsible for retinoic acid deficiency in malignant human mam…
2009
The seeming impairment of retinoid metabolism in human breast tumor cells has been attributed to the lower expression of cellular retinol binding proteins (CRBPs), of alcohol/retinol dehydrogenases, or aldehyde/retinaldehyde dehydrogenases. In a previous study we indicated that xanthine dehydrogenase (XDH) is able to oxidize actively both all-trans-retinol (t-ROL) bound to the CRBP (holo-CRBP) and all-trans-retinaldehyde (t-RAL) to all-trans-retinoic acid (t-RA) in human mammary epithelial cells (HMEC). Since both XDH and CRBP are required for the biosynthesis of t-RA, we have inspected their bioavailability in both estrogen-responsive and nonresponsive human mammary epithelial cancer cells…
Retrotranspozonu struktūra parastās priedes (Pinus sylvestris L.) genomā un to ekspresija
2014
ANOTĀCIJA Promocijas darbs izstrādāts Latvijas Valsts mežzinātnes institūtā „Silava”. Pētījuma mērķis bija identificēt aktīvos retrotranspozonus parastās priedes (Pinus sylvestris L.) genomā un raksturot to transkripcijas līmeni dažādu stresa veidu ietekmē kontrolētos apstākļos. Pētījumā izmantoti nespecifiskie retrotranspozonu marķieri balstīti uz augsti konservatīvām tRNS piesaistes vietām. Viena klona priežu rametus pakļāva dabā izplatītam karstuma stresam, kukaiņu invāzijai (priežu hermess (Pineus pini L.), kā arī mākslīgi izraisītai augu hormonu (abscīzskābes un salicilskābes) ietekmei. Darba rezultātā identificēti pārsvarā I klases mobīlo elementu pārstāvji, kā arī tos saturošie himēr…
Photoluminescent Detection of Human T-Lymphoblastic Cells by ZnO Nanorods.
2020
The precise detection of cancer cells currently remains a global challenge. One-dimensional (1D) semiconductor nanostructures (e.g., ZnO nanorods) have attracted attention due to their potential use in cancer biosensors. In the current study, it was demonstrated that the possibility of a photoluminescent detection of human leukemic T-cells by using a zinc oxide nanorods (ZnO NRs) platform. Monoclonal antibodies (MABs) anti-CD5 against a cluster of differentiation (CD) proteins on the pathologic cell surface have been used as a bioselective layer on the ZnO surface. The optimal concentration of the protein anti-CD5 to form an effective bioselective layer on the ZnO NRs surface was selected. …
