Summary

The article presents the sources, origin and theology of the Litany to the Holy Name of Jesus. The first part shows the mystery of names. It is the symbolism of man and the process of mutual communication that is the core. Names are the living souls of every being. Thanks to names, human beings are not anonymous. In ancient times, names would never be overlooked as insignificant conventional terms as they had a meaningful part in the role that a given being took on in the universe. The name has a meaning and is treated as a kind of a spiritual substance, as something real, something that truly exists. The sources of Jesus’ titles present in the Litany to the Name of Jesus are the Holy Scriptures, the writings of the Fathers of the Church and popular piety. The Litany to the Holy Name of Jesus shows the richness of the content in the Name of Jesus, which contains the truth about His deity and His infinite love for the whole of creation and especially for every human being. The Litany is a summary of the entire history of salvation, in which the name of Jesus became “a name above all names” (see Flp 2: 8-11).

Androgenesis of Ide, Leuciscus Idus (L.), Using Chub, Leuciscus Cephalus (L.), Eggs

The focus of this study was the agdrogenesis of ide, Leuciscus idus (L.), using eggs from other species. Chub, Leuciscus cephalus (L.), oocytes were genetically inactivated using UV irradiation. The eggs used in the experiment were obtained from dark-colored chub females, whereas milt was taken from yellow-colored (recessive marker) ide males. The highest yield of ide androgenesis was noted when eggs were exposed to a thermal shock 3 hrs 00 min after activation. Androgenetic origin (haploid or diploid embryos) was checked using a recessive color marker ("blond").

Economic Aspects of the Experimental Rearing of ASP, Aspius Aspius (L.), Ide, Leuciscus Idus (L.), and Dace, Leuciscus Leuciscus (L.), Under Controlled Conditions

The profitability of rearing larval asp, Aspius aspius (L.), ide, Leuciscus idus (L.), and dace, Leuciscus leuciscus (L.), was assessed in a system of 12 aquaria with a combined volume of 600 dm3. Two feeding variants were used: a) natural feed exclusively; b) natural feed plus formulated feed after seven days of rearing. All rearing variants were profitable and posed relatively low financial risks. The variant in which only natural feed was used was the most profitable. The savings incurred by the addition of formulated feed did not offset the profit lost from lower larval stock survival rates. In light of profitability, the most important aspect of larval rearing was the price of the stocking material, which was 250% higher for asp than for ide or dace. In both feeding variants, asp rearing was the most profitable and the values of the indices used to describe profitability were the best.

Impact of supplementing natural feed with dry diets on the growth and survival of larval asp, Aspius aspius (L.), and nase, Chondrostoma nasus (L.)

The aim of the study was to determine how natural feed supplemented with dry diets affects the growth rates and survival of larval asp, Aspius aspius (L.), and nase, Chondrostoma nasus (L.). The fish were reared for 21 days. Initially, the larvae were fed live Artemia sp. napulii, and a commercial feed SGP 493 (Aller Aqua) was added after 6 (A6), 8 (A8), 10 (A10), and 12 (A12) days. Depending on the feeding treatment, dietary supplements were then added to the natural feed at intervals of 1, 2, or 3 days. No statistically significant differences were noted in the growth of larval asp from groups A6 or A12, and groups A8 or A10. The relative growth rates (RGR) ranged from 18.16 (A8) to 18.61% d-1 (A12). No statistically significant differences were noted among the experimental groups of larval nase. RGR values ranged from 12.74 (A6) to 12.91% d-1 (A12). The results obtained indicate that supplementing with dry diets, which was done as early as in the first week of larval exogenous feeding, has a positive influence on the fish. This indicates that greater flexibility in feeding can be applied during the initial rearing of the larval stages of the species tested.

Abstract

This paper presents an analysis of DSC/TG/DTG thermal studies for PA6 polyamide, coal fuels and polyamide composites with these materials. The test results are aimed at comparing the thermal effects and behavior of these materials under high temperature conditions and are the basics to know of the creation and use of polymer composites with various coal fillers.

Comparing the Effectiveness of Ovopel, Ovaprim, and LH-RH Analogue Used in the Controlled Reproduction of Ide, Leuciscus Idus (L.)

The aim of the current work was to compare the effectiveness of Ovopel and Ovaprim separately and combined and LH-RH-a in the controlled reproduction of ide, Leuciscus idus (L.). The impact of the chosen hormonal preparations on ovulation, spermiation, and the quality of the gametes obtained was determined. The results confirmed the necessity of stimulating ovulation with hormone complexes and dopamine antagonists. The high effectiveness of both Ovopel and Ovaprim for ovulation stimulation in female ide was also confirmed. The greatest degree of ovulation synchronization was obtained after the application of Ovopel (eggs obtained after 36 h); however, the best results of controlled reproduction were obtained after using Ovaprim and a combination of Ovopel and Ovaprim (82 and 85% embryo survival, respectively). The highest percentage of motile sperm was noted in semen taken from males stimulated with Ovaprim (80%) and LH-RH-a (81%).

Economic Aspects of Rearing Larval ASP, Aspius Aspius (L.), and IDE, Leuciscus Idus (L.), In Closed Recirculating Systems

The profitability of rearing the rheophilic cyprinid fish species asp, Aspius aspius (L.), and ide, Leuciscus idus (L.), in two independent closed recirculating systems was evaluated. The fish were fed live Artemia nauplii exclusively. The rearing of both species was profitable and the financial risk was relatively low. From the point of view of profitability, the purchase price of stocking material was the most significant factor. The price of juvenile asp was 2.5 times higher than that of ide. Rearing larval asp was the most profitable venture.

The Effect of Stocking Density on the Growth and Survival of Larval ASP, Aspius Aspius (L.), and European Chub, Leuciscus Cephalus (L.), During Rearing Under Controlled Conditions

The aim of the study was to determine the effect of increased stocking density on the growth and survival of larval asp, Aspius aspius (L.), and European chub, Leuciscus cephalus (L.), during mass rearing under controlled conditions. Fish larvae were obtained during artificial spawning at a hatchery. The larvae were reared for 21 days in a semi-closed recirculating system at a water temperature of 25°C. They were stocked at four densities (50, 100, 150, and 200 indiv. dm-3) and were fed freshly hatched Artemia sp. nauplii. The fastest growth rate for both species was obtained at the smallest stocking density (ITL = 0.67 and 0.58 mm d-1 for asp and chub, respectively). The highest mortality of larval asp was recorded at the density of 200 indiv. dm-3 (11.68%), and for chub at the density of 50 indiv. dm-3 (40.4%). The results obtained indicated that the stocking densities applied do not have an impact on larval growth or survival in the first week of rearing.

Influence of Feeding Natural and Formulated Diets on Chosen Rheophilic Cyprinid Larvae

The aim of the work was to determine the impact of commercial feed used as an alternative diet for larval fish of the genera Leuciscus on growth and survival during rearing under controlled conditions. Larvae of chub, Leuciscus cephalus (L.), ide, Leuciscus idus (L.), and orfe (its yellow pigmented form), and dace, Leuciscus leuciscus (L.), were obtained from breeding under controlled conditions and reared for 21 days in a closed recirculating system. The control group was comprised of larvae fed Artemia nauplii. The experimental group was fed Artemia for the first seven days of rearing and then this was partially replaced with formulated feed. The experimental group was fed from day 14 exclusively with formulated feed. The results obtained indicated that the feeding treatment was highly effective. While the body sizes of the larval dace from the control group were similar to those of the experimental group, the larvae of the other species that received the mixed diet attained greater weights (chub, ide) or greater weights and lengths (orfe) by the end of the experiment.
