One such area is the creation of partial or complete realistic 3D models of real bodies in biology-in our case, trees or wood. Their great advantage is that they can capture various cases of growth deformations, interesting shapes or atypical formations. Many are temporary and unstable. An example can be a wood rotting fungus. These can then be studied outside the place of their growth and at the same time preserved for future comparisons. This leads to another possibility of their use in the educational process. We must also point out that a real 3D model with preserved dimensional proportions and true colors is a much better solution for studying than a classic photograph. We use photogrammetry to create 3D models. Its great advantage is that the 3D model is created from a series of photos that capture the part of the real object from which we want to create a partial 3D model. A classic touchscreen mobile phone is enough to get these photos. However, many problems and complications are associated with the creation of 3D models. It is not always possible to get quality photos. This can be caused by e.g. height, terrain or other obstacles. To obtain the desired partial 3D model, it is ideal if several conditions are met when obtaining photos, such as overlapping photos, sharpness, color, visible texture, etc. But in real cases it is not always possible to achieve this and therefore in our contribution we focus on the subsequent processing by which we can achieve our goal-even under the aforementioned unfavorable conditions to create a 3D model.

Fontos kiemelni, hogy a terápiára nem minden ló alkalmas, ezért fontos a terpiás munka megkezdése előtt a megfelelő ló kiválasztása és képzése. A kiválasztásnál elsősorban fontos figyelembe venni lovak a méretét, mozgását, nemét, korát, vérmérsékletét és munkakedvét. A terápiás munka során nemcsak a szakembernek kell magas szintű tudással rendelkezniük, hanem a lovaknak is. A lovasterápiára általában jól alkalmazható fajták pl.: a Haflingi, a Fjord és a Hucul.

Using the method from side 72 ewes were measured, in which the probe was placed in the inguinal-abdominal fold. Variance analysis was used to evaluate the obtained data (length, width and udder cistern area), taking into account the effect of the genotype, stage of lactation and lactation order. The average length, width and area of the left udder cistern (LUC) was 80.72 mm; 33.53 mm and 1907 mm 2 ; for the right udder cistern (RUC) 79.44 mm; 33.01 mm and 1851 mm 2. The genotype had a statistically significant effect on the LUC as well as the RUC size (P < 0.05 to 0.001). The LUC area of the IV x LC ewes was 32.7% bigger than at IV (2175 mm 2 and 1639 mm 2 , respectively), and the difference of the RUC was up to 51% in favour of the crossbreed (2227 mm 2 and 1475 mm 2 , respectively). This may be due to laterality, the natural asymmetry found in many mammals. The variability in the observed variables of the left and right udder cisterns was greater in crossbreeds than in the purebred IV ewes.

The studies on the udder parameters of sheep using for milk production recently in relation to selection for machine milking have been of interest. Genetic parameters for external udder measurements have been estimated. 1185 measurements were included in the analysis for each character of 355 ewes of 9 genotypes. Nine breeds and genotypes were included in these experiments: purebred Improved Valachian (IV), Tsigai (T), Lacaune (LC) ewes, and IV and T crosses with genetic portion of Lacaune and East Friesian (EF) – 25%, 50% and 75%. Primary data were processed using restricted maximum likelihood (REML) methodology and the multi-trait animal model, using programs REMLF90 and VCE 4.0. Heritability coefficients estimated for external udder traits were low and ranged from: h2=0.10 for udder width and for cistern depth: h2=0.45. Implications of the current study can be discussed in the future for Improved Valachian and Tsigai European dairy breeds breeding programs.

The lambing ewes were housed and managed under the same conditions over the experimental period. Milk samples for determination of SCC (Fossomatic 90, Foss Electric Co., Denmark) and contents of solids (% S), proteins (% P),fat (% F) and lactose (% L) (Multispec infrared analyzer) were taken by ewe milking in S period after intravenous application of oxytocin (5 i.u./ewe) and as part of milk recording at morning hand milking in M period. Milk samples were taken in such a way to be representative ones of the ewe’s whole milk yield. Daily milk production (MP) was also recorded in individual ewes on the day ofmilk sampling; in S period, it was calculated from a milk quantity produced within a 4 h interval and milked after

Functional traits have become important for efficient breeding schemes in the dairy goat and sheep industries, mainly in Mediterranean countries, due to increased costs of production relative to milk prices and consumers demand for safe, quality food and attention to animal

The models used in the teaching process, whatever their type, always promote understanding. The aim of this work is to demonstrate the use of a real interactive model in teaching biology in upper primary school and to investigate the feasibility of further models in the teaching process. Soil erosion in education was modelled using a real interactive model. Our model was created in the courtyard of a selected Hungarian primary school in Slovakia, where a sufficient amount of sand was available for the students to build relief shapes (hill and mountain). They watered the landscapes from a watering can with a rose, observing how the irrigation water, which was used to illustrate rainwater, eroded the soil surface. The modelling was used to investigate the results of applying 'anti-erosion' solutions to the landform. This was compared with how it looks when its free, uncovered surface is washed by rainwater. Our experience shows that the children, eager to engage in the modelling, took it as a game, and learned and experienced an important ecological phenomenon through play.

Cemeteries in Šindolka belong to the Bijelo Brdo culture, where Slavs and Magyars were buried in the 10th - 11th centuries. Surprisingly, the analysis of mtDNA has shown no maternal relationship between buried persons, since the woman belongs to haplogroup T1a and the child to haplogroup J. Since both haplogroups can be found in Near Eastern and European populations at similar frequencies, the tested samples from the tomb No. F44 cannot be clearly assigned to ethnic origin.
