Opis:
A recently uncovered assemblage of 13 coins, some of significant dating value, but all loose finds from fieldwork conducted by the Polish–Egyptian Conservation Mission, is discussed in the context of earlier coin finds recorded by the two Polish projects involved in the archaeological excavation and conservation of the Marina el-Alamein site on the Mediterranean coast of Egypt. The focus is foremost on predominantly Roman provincial coins originating from the Alexandrian mint. One of these bears a mark indicative of its use as a pendant. Hadrian bronzes, most numerous in this group, along with coins of Trajan and Antoninus Pius corroborate a peak in the development of the town in the 2nd century AD, while late Roman imperial specimens are direct evidence for its continued functioning in the late antique period.

Opis:
A perfect geodominating set in a graph G is a geodominating set S such that any vertex v ∈ V(G)\S is geodominated by exactly one pair of vertices of S. A k-perfect geodominating set is a geodominating set S such that any vertex v ∈ V(G)\S is geodominated by exactly one pair x, y of vertices of S with d(x, y) = k. We study perfect and k-perfect geodomination numbers of a graph G.

Opis:
The 2020/2021 pandemic year has been difficult for teachers at all levels of education including higher education. There was a need to switch quickly to another type of education that would achieve the same objectives as before. How did the university teachers face this challenge? What consequences have been drawn for university teaching in general? We propose to take a global perspective of the state of current university pedagogy to highlight the need to renovate its approaches and to put the learner at the center of the process so to provide pedagogical support in his learning. We will analyze the results of three surveys concerning remote teaching and learning in Poland and in Europe. Finally, we will show what tools can be used to better monitor students` learning in virtual classes.

Opis:
The concept of generalized $k$-connectivity $ \kappa_k (G) $, mentioned by Hager in 1985, is a natural generalization of the path-version of the classical connectivity. The pendant tree-connectivity $ \tau_k (G) $ was also introduced by Hager in 1985, which is a specialization of generalized $k$-connectivity but a generalization of the classical connectivity. Another generalized connectivity of a graph $G$, named $k$-connectivity $ \kappa_k^' (G) $, introduced by Chartrand et al. in 1984, is a generalization of the cut-version of the classical connectivity. In this paper, we get the lower and upper bounds for the difference of $ \kappa_k^' (G) $ and $ \tau_k(G) $ by showing that for a connected graph $G$ of order $n$, if $ \kappa_k^' (G) \ne n − k + 1 $ where $ k \ge 3 $, then $ 1 \le \kappa_k^' (G) − \tau_k (G) \le n − k $; otherwise, $ 1 \le κ_k^' (G) − \tau_k(G) \le n − k + 1 $. Moreover, all of these bounds are sharp. We get a sharp upper bound for the 3-connectivity of the Cartesian product of any two connected graphs with orders at least 5. Especially, the exact values for some special cases are determined. Among our results, we also study the pendant tree-connectivity of Cayley graphs on Abelian groups of small degrees and obtain the exact values for $ \tau_k(G) $, where $G$ is a cubic or 4-regular Cayley graph on Abelian groups, $ 3 \le k \le n $.

Opis:
A vertex k-labeling ϕ : V (G) → {1, 2, . . . , k} on a simple graph G is said to be a distance irregular vertex k-labeling of G if the weights of all vertices of G are pairwise distinct, where the weight of a vertex is the sum of labels of all vertices adjacent to that vertex in G. The least integer k for which G has a distance irregular vertex k-labeling is called the distance irregularity strength of G and denoted by dis(G). In this paper, we introduce a new lower bound of distance irregularity strength of graphs and provide its sharpness for some graphs with pendant vertices. Moreover, some properties on distance irregularity strength for trees are also discussed in this paper.
