Povzetek: Česen v Sloveniji predstavlja dobro poznano čebulnico, ki je doma v vsakem vrtu, vedno več pa ga pridelujemo tudi v tržni pridelavi. V Sloveniji imamo v pridelovanju česna dolgoletno tradicijo, na kar kažejo stare sorte s Ptujskega polja. Za prehrano uporabljamo mlade stroke rastočih rastlin in dozorele čebulice oziroma stroke. Česen velja za naravni antibiotik in že star pregovor pravi, da česen devet bolezni odžene. Publikacija, ki je pred vami, predstavlja kompleksno inventarizacijo genskih virov česna zbranih na Kmetijskem inštitutu Slovenije in shranjenih v Slovenski rastlinski genski banki. Z uporabo predpisanih deskriptorjev za vrste Allium sativum sp., meritvami morfometričnih lastnosti in slikovnim gradivom smo prvič do sedaj opisali ter ovrednotili 61 genskih virov česna (Allium sativum L.).

Povzetek: The structural and magnetic properties of iron-cobalt alloys (FeCoV) were compared to those of electrical steel alloys. The latter are widely used for the ferromagnetic cores of electric motors. However, the as-cast and rolled FeCoV alloys, which were ana lysed, showed enhanced magnetic properties compared to electrical steel alloys. Moreover, since they can be cast directly into the final shape of the rotor’s main structure (excluding the pole shoes, which must be laminated) for a wound-rotor synchronous electric motor, the production becomes more cost-effective and energy-efficient. In addition, the performance of the electric motor is improved in terms of mechanical output power and energy efficiency

Povzetek: For a non-decreasing sequence $S=(s_1,s_2,\ldots)$ of positive integers, a partition of the vertex set of a graph $G$ into subsets $X_1,\ldots, X_\ell$, such that vertices in $X_i$ are pairwise at distance greater than $s_i$ for every $i\in\{1,\ldots,\ell\}$, is called an $S$-packing $\ell$-coloring of $G$. The minimum $\ell$ for which $G$ admits an $S$-packing $\ell$-coloring is called the $S$-packing chromatic number of $G$. In this paper, we consider $S$-packing colorings of the integer distance graphs with respect two positive integers $k$ and $t$, which are the graphs whose vertex set is $\mathbb{Z}$, and two vertices $x,y\in \mathbb{Z}$ are adjacent whenever $|x-y|\in\{k,t\}$. We complement partial results from two earlier papers, thus determining all values of the $S$-packing chromatic numbers of these distance graphs for all sequence $S$ such that $s_i\le 2$ for all $i$. In particular, if $S=(1,1,2,2,\ldots)$, then the $S$-packing chromatic number is $2$ if $k+t$ is even, and $4$ otherwise, while if $S=(1,2,2,\ldots)$, then the $S$-packing chromatic number is $5$, unless $\{k,t\}=\{2,3\}$ when it is $6$; when $S=(2,2,2,\ldots)$, the corresponding formula is more complex.
