Regulatory networks underlying mycorrhizal development delineated by genome-wide expression profiling and functional analysis of the transcription fa…

2017

Background: Ectomycorrhizal (ECM) fungi develop a mutualistic symbiotic interaction with the roots of their host plants. During this process, they undergo a series of developmental transitions from the running hyphae in the rhizosphere to the coenocytic hyphae forming finger-like structures within the root apoplastic space. These transitions, which involve profound, symbiosis-associated metabolic changes, also entail a substantial transcriptome reprogramming with coordinated waves of differentially expressed genes. To date, little is known about the key transcriptional regulators driving these changes, and the aim of the present study was to delineate and functionally characterize the trans…

Effects of pyrolysis temperature on the hydrologically relevant porosity of willow biochar

2018

Biochar pore space consists of porosity of multiple length scales. In direct water holding applications like water storage for plant water uptake, the main interest is in micrometre-range porosity since these pores are able to store water that is easily available for plants. Gas adsorption measurements which are commonly used to characterize the physical pore structure of biochars are not able to quantify this pore-size range. While pyrogenetic porosity (i.e. pores formed during pyrolysis process) tends to increase with elevated process temperature, it is uncertain whether this change affects the pore space capable to store plant available water. In this study, we characterized biochar poro…

Temperamental profile and attachment in preterm children with moderate prematurity during the preschool age

2012

Background Preterm birth is characterized by prematurity (functional and organic immaturity related to gestational age <32 weeks) and constitutes not only a risk condition for the child’s survival and the development characteristics after the birth, also represents a specific factor that is responsible for the. Neonatal developmental trajectory is characterized by the interruption of prenatal maturation processes that guide the development of the temperament (Hack, Fanaroff, 1999; Saigal, 2006), as well as the precursors of the attachment bond. In particular, with regard to the temperament, the literature evidences the existence of temperamental profiles characterized by motor restlessness,…

Adrb3 adrenergic receptor is a key regulator of human myometrial apoptosis and inflammation during chorioamnionitis1

2008

The pathophysiology underlying preterm labor triggered by inflammatory conditions such as chorioamnionitis remains largely unclear. It has already been suggested that beta-3 adrenergic (ADRB3) agonists might be of interest in the pharmacological management of preterm labor. Although there is evidence implicating ADRB receptors in the control of inflammation, there are minimal data relating specifically to ADRB3. To explore the cellular consequences of chorioamnionitis and detect apoptosis, we first performed immunostaining and Western blot experiments on human myometrial samples obtained from women with confirmed chorioamnionitis. We then developed an in vitro model of chorioamnionitis by i…

„Zaļo” krasta preterozijas risinājumu modeļteritorijas Lapmežciemā, Plieņciemā un Ķesterciemā

2015

Bakalaura darbs ir veltīts jūras krasta procesiem, krastu attīstībai, izmantošanai un aizsardzībai, īpašu uzmanību pievēršot „zaļajiem” preterozijas risinājumiem. Darba mērķis ir novērtēt „zaļo” krasta preterozijas pasākumu pielietošanas efektivitāti Plieņciemā, Lapmežciemā un Ķesterciemā. Pētījuma ietvaros, izmantojot krasta šķērsprofilu nivelēšanā iegūtos datus, tika noteiktas krasta zonas virsūdens daļas reljefa izmaiņas kārklu stādījumu un sētiņu tiešā tuvumā. Pamatojoties uz iegūtajiem rezultātiem, tika novērtēta šo preterozijas būvju eolās akumulācijas veicināšanas efektivitāte un cita iespējamā ietekme novērojumu periodā.

Gamified Cognitive Inoculation Against Misinformation Associated with Temperament and Need for Closure as Predictive Factors in Adults

2020

Eksperimentālā pētījumā (N = 396) tika pārbaudīta ietekme sava veida “mentālai vakcīnai” pret maldinošu informāciju – 21.gadsimta globālu problēmu, kas tiek apzināti modelēta pēc līdzīga principa kā izplatās bioloģiskie vīrusi. Dezinformācija ne vien apdraud globālo drošību, bet arī ietekmē indivīdu psihisko veselību, provocējot ar trauksmi un stresu saistītos traucējumus un depresiju,kas īpaši izgaismojies COVID-19 globālās pandēmijas laikā. Līdzīgi kā medicīnā vakcīna ar novājinātu vīrusa devu veido rezistenci pret infekcijas saslimšanu, ar kognitīvās pretestības nostiprināšanu tiek veidota attieksmes noturība pret pārliecināšanu un propagandu, iekļaujot manipulācijā spēles principu.

PROCESSI DI ATTENZIONE IN BAMBINI DI ETA’ PRESCOLARE NATI GRAVEMENTE E MODERATAMENTE PRETERMINE

2014

Introduzione La nascita pretermine sia severa (GA1500g), può indurre fin dai primi anni di vita compromissioni di diversi processi cognitivi (Bhutta et al. 2002; Aylward, 2005);questo sottolinea l’importanza di anticipare in età precoce i percorsi di assessment (Perricone et al. 2012).Lo studio indaga la possibile compromissione dei processi di attenzione in bambini nati pretermine di età prescolare. Metodo Lo studio verifica l’esistenza di differenze significative tra bambini/e nati/e gravemente pretermine, moderatamente pretermine e a termine, rispetto ai processi di attenzione in età prescolare. Sono stati coinvolti 120 bambini (età M=5.2 anni) di cui: 25 nati gravemente pretermine (GA M…

Modal Consequence Relations Extending S4.3: An Application of Projective Unification

2016

We characterize all finitary consequence relations over $\mathbf{S4.3}$ , both syntactically, by exhibiting so-called (admissible) passive rules that extend the given logic, and semantically, by providing suitable strongly adequate classes of algebras. This is achieved by applying an earlier result stating that a modal logic $L$ extending $\mathbf{S4}$ has projective unification if and only if $L$ contains $\mathbf{S4.3}$ . In particular, we show that these consequence relations enjoy the strong finite model property, and are finitely based. In this way, we extend the known results by Bull and Fine, from logics, to consequence relations. We also show that the lattice of consequence relation…

Computing Subdivision Surface Intersection

2003

Computer surface intersections is fundamental problem in geometric modeling. Any Boolean operation can be seen as an intersection calculation followed by a selection of parts necessary for building the surface of the resulting object. This paper deals with the computing of intersection curveson subdivision surfaces (surfaces generated by the Loop scheme). We present three variants of our algorithm. The first variant calculates this intersection after classification of the object faces into intersecting and non-intersecting pairs of faces. the second variant is based on 1-neighborhood of the intersecting faces. The third variant uses the concept of bipartite graph.
