This experiment was carried out to investigate the difference of electrophoretical pattern of fertile and infertile eggs. DEAE-Cellulose column chromatography for fertile egg white and infertile egg white were carried out to find paotein bands. Individual protein bands were examined for electrophoretic mobility and compared to the patterns of egg white protein. The results obtained were summarized as follows. (1) In DEAE-Cellulose column chromatography, both of fertile and infertile egg whites were showed similarly peaks(280 nm), the peaks were founded 10, respectively. (2) In electrophoresis of egg white protein, electrophoretic pattern of fertile and infertile eggs was almost similar, the concentration of egg white protein in fertile and infertile eggs was in the rank of ovalbumin, conalbuin, globulins, postalbumins, preconalbumins, ovomacroglobulin, flavoprotein.
Hydrurus foetidus(Chrysophyceae): an update and request for observations
Dag Klaveness 한국조류학회I 2019 ALGAE Vol.34 No.1
Hydrurus foetidus is a cold-water golden alga (Chrysophyceae) found in fast-flowing rivers mainly during time ofsnowmelt. It has primarily been studied by scientists located near alpine or northern locations, but there are also observationsboth in south and north America, Russia, Japan, in the Hope Bay area (Antarctica) and Himalaya. If and whereenvironmental conditions are appropriate, Hydrurus may be distributed “worldwide.” More information is wanted fromareas where its presence may be expected.
RICCI CURVATURE, CIRCULANTS, AND EXTENDED MATCHING CONDITIONS
Dagli, Mehmet,Olmez, Oktay,Smith, Jonathan D.H. Korean Mathematical Society 2019 대한수학회보 Vol.56 No.1
Ricci curvature for locally finite graphs, as proposed by Lin, Lu and Yau, provides a useful isomorphism invariant. A Matching Condition was introduced as a key tool for computation of this Ricci curvature. The scope of the Matching Condition is quite broad, but it does not cover all cases. Thus the current paper introduces extended versions of the Matching Condition, and applies them to the computation of the Ricci curvature of a class of circulants determined by certain number-theoretic data. The classical Matching Condition is also applied to determine the Ricci curvature for other families of circulants, along with Cayley graphs of abelian groups that are generated by the complements of (unions of) subgroups.

More than a decade after their development and first wave of deployment, Six Sigma and Lean Manufacturing have recently returned on the corporate agendas of a larger number of corporations across industries and supply chains. In the wake of their re-surge, this commentary addresses the evolution, context, content and deployment patterns of the two distinct management concepts. It also analyses claims in the business press that a merger is taking place between Six Sigma and Lean Manufacturing. Here, it is found that there is not enough evidence to broadly support such claims, and it is only concluded that there is some evidence of an early tend towards a merger and that a possible merger would have many synergies and advantages. Finally, an example from a Scandinavian manufacturing company is provided that explains how Six Sigma and Lean Manufacturing can be used in a beneficial way for companies to reach world-class performance.
LINEAR AND NON-LINEAR LOOP-TRANSVERSAL CODES IN ERROR-CORRECTION AND GRAPH DOMINATION
Dagli, Mehmet,Im, Bokhee,Smith, Jonathan D.H. Korean Mathematical Society 2020 대한수학회보 Vol.57 No.2
Loop transversal codes take an alternative approach to the theory of error-correcting codes, placing emphasis on the set of errors that are to be corrected. Hitherto, the loop transversal code method has been restricted to linear codes. The goal of the current paper is to extend the conceptual framework of loop transversal codes to admit nonlinear codes. We present a natural example of this nonlinearity among perfect single-error correcting codes that exhibit efficient domination in a circulant graph, and contrast it with linear codes in a similar context.
The Exponential Cubic B-spline Algorithm for Equal Width Equation
I. Dag,O. Ersoyy 장전수학회 2015 Advanced Studies in Contemporary Mathematics Vol.25 No.4
The exponential B-spline functions are used to form an approximate solutions for numerical methods. The collocation method with the approximate solution of the exponential B-spline is build up to nd the numerical solutions of the Equal Width Equation(EWE). The contribution on the experimental accuracy of the collocation method in solving the nonlinear equation are searched experimentially. The comparison of the results of the suggested method is done with ones obtained with variants of B-spline nite element methods.
