A subcategory W of an abelian category is called wide if it closed under kernels, cokernels, and extensions. Wide subcategories are interest in representation theory because their links to other homological combinatorial objects, established among others by Ingalls–Thomas Marks–Š?oví?ek. If d?1 integer, then Jasso introduced the notion d-abelian categories, where extensions have been replaced l...

Private forests in Slovenia and Bosnia-Herzegovina are important resources for national economic development. Based on differences in the proportion of private forests, the countries differ substantially with regard to the role of private forest owners, as well as the conditions of owner interest associations in the forest policy processes. Since private forest owners are so diverse, there is a...

where N is the least common multiple of those common differences (or moduli) n1, · · · , nk. For a positive integer m, (1) is said to be an m-cover of Z if its covering multiplicity is not less than m, and an exact m-cover of Z if σ(x) = m for all x ∈ Z. Note that k > m if (1) forms an m-cover of Z. Clearly the covering function σ : Z → Z is constant if and only if (1) forms an exact m-cover of...

Š��� I., H������� M. (2004): Image data of crumb structure of bread from flour of Czech spring wheat cultivars. Czech J. Food Sci., 22: 133–142. Baking quality of flour from six wheat cultivars (harvest 2002 and 2003), belonging to the quality classes A and B, was evaluated using the fermented dough test. Analytical traits of kernel and flour showed differences between the classes which were co...

Sedláčková P., Horáčková Š., Shi T., Kosová M., Plocková M. (2015): Two different methods for screening of bile salt hydrolase activity in Lactobacillus strains. Czech J. Food Sci., 33: 13–18. Bile salt hydrolase (BSH) activity of intestinal bacteria (including lactobacilli) is one of the indirect ways of decreasing a cholesterol level in human body. Tested Lactobacillus strains were isolated f...

This study investigates the relationship between the variability in the temporal alignment of turn initiations and the pragmatics of interpersonal communication. The data come from spontaneous, task-oriented dialogues in Standard American English. In addition to analyzing the temporal aspects of turn-taking behavior in general, we focus on the timing of turn-initial single word grounding respon...

The stable isotopic composition of dissolved inorganic carbon (υ13C-DIC) was investigated as a potential tracer of streamflow generation processes at the Sleepers River Research Watershed, Vermont, USA. Downstream sampling showed υ13C-DIC increased between 3–5‰ from the stream source to the outlet weir approximately 0Ð5 km downstream, concomitant with increasing pH and decreasing PCO2. An incre...

forest property (on average < 3 ha) and fragmentation (3 plots on average) (The Slovenian Forest Service, 2005). Private forest management is further hindered by constant processes in the society which are related to an increasing number of owners due to partible inheritance and the diminishing sizes of forest property as well as a fall in the percentage of rural population, which indirectly in...
