Determining the Set of Concept Map Based Tasks for Computerized Knowledge Self-Assessment

2012

Demands for educated labor force with well-integrated cognitive structures call for necessity to use in educational institutions appropriate teaching and knowledge assessment methods directed towards fine development and assessment of students’ conceptual understanding. Concept maps as a kind of mental models have great potential in knowledge assessment due to several significant advantages. However, a taxonomy of possible concept mapping tasks has not been developed yet. The paper considers the problem of extending a set of concept mapping tasks in the already developed concept map based knowledge assessment system. The possible types of tasks are investigated from the point of view of the…

Impact of a Three Amino Acid Deletion in the CH2 Domain of Murine IgG1 on Fc-Associated Effector Functions

2008

Abstract Four murine IgG subclasses display markedly different Fc-associated effector functions because of their differential binding to three activating IgG Fc receptors (FcγRI, FcγRIII, and FcγRIV) and C1q. Previous analysis of IgG subclass switch variants of 34-3C anti-RBC monoclonal autoantibodies revealed that the IgG1 subclass, which binds only to FcγRIII and fails to activate complement, displayed the poorest pathogenic potential. This could be related to the presence of a three amino acid deletion at positions 233–235 in the CH2 domain uniquely found in this subclass. To address this question, IgG1 insertion and IgG2b deletion mutants at positions 233–235 of 34-3C anti-RBC Abs were …

STUDENTS’ READINESS FOR MASSIVE OPEN ONLINE COURSES (MOOCS) IN LATVIA

2020

MOOCs have gained popularity increasingly more and more with their open online approach and mass engagement. They could play an important role in higher education. But the question remains whether students are ready for it. The aim of the study was to find out what students' understanding of online learning was and to what extent they were prepared for MOOCs. A research question was raised: there is a relationship among technical competencies, socio-communication competencies, self-efficacy, self-directedness and MOOCs readiness. The survey-monkey's electronic platform was used for data extraction. Open-ended questions were asked on the 4-point Likert scale. According to the research questi…

Pulsed EPR determination of water accessibility to spin-labeled amino acid residues in LHCIIb.

2009

Membrane proteins reside in a structured environment in which some of their residues are accessible to water, some are in contact with alkyl chains of lipid molecules, and some are buried in the protein. Water accessibility of residues may change during folding or function-related structural dynamics. Several techniques based on the combination of pulsed electron paramagnetic resonance (EPR) with site-directed spin labeling can be used to quantify such water accessibility. Accessibility parameters for different residues in major plant light-harvesting complex IIb are determined by electron spin echo envelope modulation spectroscopy in the presence of deuterated water, deuterium contrast in …

Demonstration and partial characterization of an intermediate HBcAG (Dane particle) population.

1981

Abstract Hepatitis-B core antigen (HBcAg) was released from Dane particles previously separated from anti-HBc by repeated pelleting through sucrose gradients separated into three HBcAg populations when analysed by cesium chloride density gradient centrifugation. Heavy HBcAg particles banded at a density of 1.355 gm/ml, intermediate HBcAg particles at a density of 1.33 gm/ml, and light mediate HBcAg particles at a density of 1.30 gm/ml. Like heavy HBcAg particles, intermediate HBcAg particles contained DNA polymerase activity, but the ratio of HBcAg to DNA polymerase activity was significantly different in both populations. Intermediate HBcAg particles could not be separated from heavy HBcAg…

A smallest irregular oriented graph containing a given diregular one

2004

AbstractA digraph is called irregular if its vertices have mutually distinct ordered pairs of semi-degrees. Let D be any diregular oriented graph (without loops or 2-dicycles). A smallest irregular oriented graph F, F=F(D), is constructed such that F includes D as an induced subdigraph, the smallest digraph being one with smallest possible order and with smallest possible size. If the digraph D is arcless then V(D) is an independent set of F(D) comprising almost all vertices of F(D) as |V(D)|→∞. The number of irregular oriented graphs is proved to be superexponential in their order. We could not show that almost all oriented graphs are/are not irregular.
