premii Ad Astra

Asociația Ad Astra a anunțat câștigătorii Premiilor Ad Astra 2022: http://premii.ad-astra.ro/. Proiectul și-a propus identificarea și popularizarea modelelor de succes, a rezultatelor excepționale ale cercetătorilor români din țară și din afara ei.

Asociatia Ad Astra a cercetatorilor romani lanseaza BAZA DE DATE A CERCETATORILOR ROMANI DIN DIASPORA. Scopul acestei baze de date este aceea de a stimula colaborarea dintre cercetatorii romani de peste hotare dar si cu cercetatorii din Romania. Cercetatorii care doresc sa fie nominalizati in aceasta baza de date sunt rugati sa trimita un email la cristian.presura@gmail.com

Application of QuEChERS – High Performance Liquid Chromatography with Postcolumn Fluorescence Derivatization (HPLC-FLD) method to analyze Eprinomectin B1a residues from a pour-on conditioning in bovine edible tissues

A QuEChERS in house method for determining the marker residue of eprinomectin (eprinomectin B1a) by HPLC-FLD in bovine tissues and milk provided from treated animals was developed and applied. Briefly: all samples were extracted with acetonitrile using a dispersive SPE purification stage. The ascertained detection limits were 1 μg kg-1 and the quantification limits 2 μg kg-1. Recoveries on tissue samples fortified in the range of 10 μg kg-1 to

Reachability and Recurrence in a Modular Generalization of Annihilating Random Walks (and lights-out games) to hypergraphs

We study a discrete asynchronous dynamical system on hypergraphs that can be regarded as a natural extension of annihilating walks along two directions: first, the interaction topology is a hypergraph; second, the number of particles at a vertex of the hypergraph is an element of a finite ring Z_p of integers modulo an odd number p>= 3. Equivalently, particles move on a hypergraph, with a moving particle at a vertex being replaced by one indistinguishable

Isolated human uterine telocytes: immunocytochemistry and electrophysiology of T-type calcium channels.

Recently, telocytes (TCs) were described as a new cell type in the interstitial space of many organs, including myometrium. TCs are cells with very long, distinctive extensions named telopodes (Tps). It is suggested that TCs play a major role in intercellular signaling, as well as in morphogenesis, especially in morphogenetic bioelectrical signaling. However, TC plasma membrane is yet unexplored regarding the presence and activity of ion channels

Near-infrared low-level laser stimulation of telocytes from human myometrium

Telocytes (TCs) are a brand-new cell type frequently observed in the interstitial space of many organs (see www.telocytes.com ). TCs are defined by very long (tens of micrometers) and slender prolongations named telopodes. At their level, dilations-called podoms (~300 nm), alternate with podomers (80-100 nm). TCs were identified in a myometrial interstitial cell culture based on morphological criteria and by CD34 and PDGF receptor alpha (PDGFRα)

Eastern Mysticism and Western Scholastics in Glass Painting Iconography

The aim of this work consists in the widening and deepening of the knowledge about the influence of the Western cultural trends, the Byzantine ones (coming from the Southern and Eastern Orthodox Europe) and the native ones exerted on the Glass Painting of the 19th in the Romanian Countries. The research is based on a comparative study on Glass Painting in Transylvania and Banat with its modes of expression in the European space. Besides its apotropaic

A connection between Jacobi-Stirling numbers and Bernoulli polynomials

A finite discrete convolution involving the Jacobi-Stirling numbers of both kinds is expressed in this paper in terms of the Bernoulli polynomials.

Dependence of solvent quality on the composition of copolymers: Experiment and theory for solutions of P(MMA-ran-t-BMA) in toluene and chloroform

The interaction of toluene with P(MMA-ran-t-BMA) and with the corresponding homopolymers was determined via vapor pressure measurements at 30, 50 and 70 °C. A unified thermodynamic approach served for the modeling of the results. It is capable of describing the behavior of the different solutions by means of two adjustable parameters, one representing the effective number of solvent segments and the other accounting for the interactions between
