the zarankiewicz number z(b; s) is the maximum size of a subgraph of kb,b which does not contain ks,s as a subgraph. the two-color bipartite ramsey number b(s, t) is the smallest integer b such that any coloring of the edges of kb,b with two colors contains a ks,s in the rst color or a kt,t in the second color.in this work, we design and exploit a computational method for bounding and computin...
Members of the bone morphogenetic protein (BMP) family play diverse roles in multiple developmental processes. However, in the mouse, mutations in many BMPs, BMP receptors and signaling components result in early embryonic lethality making it difficult to analyze the role of these factors during organogenesis or tissue homeostasis in the adult. To bypass this early lethality, we used an organ c...
Objective(s) The use of co-culture cells as well as extra cellular matrix are among those strategies that have been employed to direct mesenchymal stem cell (MSC) bone differentiation in culture. In this regard, there is no study considering the effects of Matrigel on mesenchymal stem cell (MSC) in vitro bone differentiation. This was the subject of the present study. Materials and Methods ...
Motivated by the increasing energy consumption of supercomputing for weather and climate simulations, we introduce a framework for investigating the bit-level information efficiency of chaotic models. In comparison with previous explorations of inexactness in climate modelling, the proposed and tested information metric has three specific advantages: (i) it requires only a single high-precision...
In industriellen Anforderungsdokumenten werden Aussagen hinsichtlich nichtfunktionaler Anforderungen häufig sehr vage formuliert. Äußerungen wie „Wir wollen ein leicht wartbares System“ machen eine Validation der Aussage schwierig und geben wenig Hilfestellung während der Systementwicklung. Typische Probleme mit solchen Aussagen sind, dass unklar ist, wie man ermittelt was Wartbarkeit für das S...
Ex vivo expansion of human umbilical cord blood cells (HUCBC) is explored by several investigators to enhance the repopulating potential of HUCBC. The proliferation and expansion of human hematopoietic stem cells (HSC) in ex vivo culture was examined with the goal of generating a suitable clinical protocol for expanding HSC for patient transplantation. Using primary human mesenchymal stem ...
selon les pédagogues, la culture étant un élément très important dans le processus de lapprentissage de langue étrangère et la maîtrise de la compétence linguistique requiert celle de la compétence culturelle. la littérature dun pays est comme un miroir qui reflète bon nombre daspects culturels, cest pourquoi avec le choix dun texte littéraire convenable, lenseignant peut assurer à la fois lapp...
from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
The present research aims to study reliability, validity and manner of Zuckerman sensation-seeking scale (SSS) particularly with changes of culture among the students of technical universities in Tehran, Therefore, 668 students (332 females and 336 males were randomly selected from five technical and engineering universities (Tehran University) Sharif University of Technology, Khajeh Nasir Univ...
Abstract Stone fruits are valuable because of high nutritional. propagation of the same rootstocks is vital in horticulture. The aim of the present study was to investigate some concentrations of growth regulators such as benzylaminopurine (BAP), gibberellic acid (GA3), naphthalene acetic acid (NAA), indole butyric acid (IBA) in shoot germination and rooting of myrobalan 29c. This experiment w...
