Industries in close proximity to residential districts are a historical phenomenon of urban development frequently causing air quality problem in European cities. Mladá Boleslav, the long-time centre ...of the automobile industry in the Czech Republic, is typical example of urban development. However, this air pollution source reconnaissance study found a source of currently increasing importance for the European cities, wood burning. Receptor modelling, time series of organic tracers for wood and coal burning, small-scale multiple-site PM10 monitoring and mobile PM10 measurement were combined to identify sources of fine (PM0.15-1.15) and coarse (PM1.15-10) particles in a residential district of Mladá Boleslav in winter 2013. The receptor model was applied to hourly concentrations of organic and elemental carbon in fine and 27 elements in fine and coarse aerosol particles at a receptor site. Multiple-site measurements with PM10 monitors showed no statistically significant differences among the monitors. Thus, the source apportionment derived from the central site data should apply to the entire residential district. Campaign average PM10 (33.9 μgm−3) consisted of 88% fine particles. Wood burning (49%), coal combustion (34%), traffic (16%), and industry (1%) were identified as the fine particle sources while combined wood burning and coal dust (80%), road dust with salt (14%), and abrasion of car brakes (6%) were identified the coarse particle sources. The large contributions of wood and coal combustion were surprising for this residential district that is a block of flats with district heating. High correlations were observed between the wood combustion contributions and the levoglucosan and mannosan concentrations. The homohopane index of 0.05 indicated lignite combustion. Peak concentrations in excess of 500 μgm−3 of PM10 recorded during mobile measurements along with visible plumes from home heating, support the source apportionment of the fine particle mass.
•PMF revealed wood combustion for home heating to outclass industrial source.•Mannosan and levoglucosan in PM1 supported PMF receptor model results.•Lignite combustion was indicated by the homohopane index of 0.05.•Plumes from home chimneys caused PM10 up to 500 μgm−3 at street level.
Text je koncipován jako teoretická studie vycházející v návaznosti na český překlad knihy Linking practice and theory: The pedagogy of realistic teacher education od F. A. J. Korthagena et al. Výklad ...je ve studii rozvržen do dvou částí. V první části jsou představeny vůdčí (programové) myšlenky Korthagenovy koncepce; text je převážně popisný, nemá ambici kritické analýzy. O to jde v druhé části studie, kde se autoři vracejí k vybraným myšlenkám Korthagenovy koncepce, rozebírají je a podrobují je diskusi v širším kontextu novějších domácích i zahraničních přístupů a poznatků. Zaměřují se na tři související problémové okruhy: (1) Povaha vztahu teorie a praxe – nedocenění Teorie s velkým T? (2) Význam reflexe v učitelově profesním rozvoji – vyprázdněnost s ohledem na učivo? (3) Podpora profesního učení – redukované pojetí supervize? V závěru studie je otevřena otázka, jak prezentovanou koncepci využít v kontextu učitelského vzdělávání v České republice.

A study was carried out on 11 horse breeds (Akhal Teke (n = 23), English Thoroughbred (n = 23), Arabian Thoroughbred (n = 18), Czech Warm-Blood (n = 21), Old Kladrubian horse (n = 20), Hucul horse (n ...= 20), Czech-Moravian Belgian horse (n = 20), Noriker horse (n = 7), Silesian Noriker (n = 14), Haflinger (n = 20), Shetland pony (n = 20)) to determine the shape and size of chestnuts. Chestnuts of 206 horses classified in three phylogeny classes were measured and drawn. The necessary data (breed; sex; name; sire; dam; sire of dam; age of horse; colour of horse; colour of the chestnut; bone) were entered into a special form. In the form the outlines of the shapes of the chestnuts were drawn; using a calliper we measured the protrusion of the chestnut at its highest point and the width at the widest part of the chestnut. We found no identical or similar shapes of the chestnuts within the breed or phylogeny class. We confirmed that the outlines of the chestnuts can be used as identifying marks because they are unique for each horse. We also tried to determine how the size of the chestnut is related to the strength of the skeleton but we failed to prove this dependence statistically. Using the general linear model we discovered a highly significant effect of the phylogeny class on the height and width of the chestnuts on all four limbs. The age factor has a highly significant effect on the width of the chestnut on both front legs. Sex has a significant effect on the height of the chestnut on both hind legs.
Emancipace didaktiky cizích jazyků, resp. didaktiky určitého konkrétního cizího jazyka, je dlouhodobým a nelineárním procesem, u nás nastoupeným již v 50. letech minulého století. Jeho klíčovou ...součástí jsou otázky identity, tedy explicitní vymezení objektu, předmětu a metodologie didaktiky cizích jazyků na základě analýzy vývoje, současného stavu poznání a různých pojetí a trendů. Diskutovány jsou otázky identity didaktiky cizích jazyků jako plnoprávné vědecké disciplíny, a to na rovině obecné, tj. otázky společné všem oborovým didaktikám, tak na rovině specifické, tedy týkající se výlučně různých aspektů didaktiky cizích jazyků.

The aim of this study was to evaluate the conformation of stallions of the breeds American Quarter Horse (AQH), American Paint Horse (APH), Appaloosa (Appa), the Lipizzaner horse (LH) and the Old ...Kladruby horse (OKH). Representatives of these breeds are characterized as the descendants of horses on the base of the Arab-Berber blood. Twenty-four body dimensions were measured. AQH, APH and Appa significantly differ from LK and OKH in 23 of the 24 observed effects. To be precise, they are as follows: smaller wither height as measured by stick, lower at the tail-set, longer neck, narrower chest, longer oblique body length, wider front pelvis length, longer pelvis bones, longer femur bones, shorter hind cannons. A significant difference was found in the length of the humerus, as the humerus of OKH is longer by 2.34 cm than that of APH. LH differs significantly from Appa and OKH in the tape length of its head.

The main focus of our work was to collect basic body measurements of donkey population in the Czech republic and determine the factors that influence these body measurements and hipometric indexes. ...The following measurements were recorded: height at withers, chest circumference and metacarpus interference. Based on the collected data, we were able to calculate the hipometric indexes as follows: index of boniness, skeleton strength index, body mass index and croup height index. From a total of 331 individuals of donkey species living in the Czech republic we managed to collect 50 samples. These were subjected to a general linear model (GLM) and multiplex comparison statistical analysis. We managed to prove a significant difference between donkeys born in the Czech republic and the ones born abroad for all the measurements. Specifically, the metacarpus circumference depended on the gender, having its impact on the hipometric indexes as well; the boniness index and skeleton strength index were also gender-dependent.

The aim of this study was to evaluate the movement in walk and trot in the Welsh Mountain Pony and the Welsh Pony. Length of stride in walk, length of stride in trot and the frequency were measured. ...The following effects were chosen: sex, breed section, country of origin and scapula angle. In total, 57 individuals of the Welsh Pony and Cob breeds were entered into the database (37 animals were section A and 20 animals section B). We measured the data with a laser measure and a special pedometer between March 2010 and April 2012. The relationship between the length of stride in walk and trot was investigated in comparison to the wither height, the animal's sex, its country of origin, breed section and the angle of the scapula. A significant influence was observed for the effect of section. By comparing the spaciousness in walk and trot according to the chosen effects of sex, scapula angle, adherence to section and country of origin, we proved a highly significant influence of the scapula angle and a significant one of the breed. Multiple comparisons showed a significant effect of wither height where the difference in wither height between the individual sections was more than 10 cm.
The objective of the study was to analyse the dynamics of growth of the Czech warm-blood young horses and to evaluate the effect of rearing facilities for testing young horses (RFT) on the increase ...in body measurements of the young horses. Groundwork data were obtained from the database of the Czech Warm-Blood Horse Breeders Association which contains data on the regular grading of the young horses in the RFT facilities. Data from the year 2001 to 2011 from 7 RFT facilities for young horses were entered in the basic database. Statistical processing of the database using the GLM method revealed that the RFT had a statistically significant effect on the tape-measure, heart-girth and bone. By multiple comparisons of the individual effects using the Tukey-B method we discovered statistically significant differences in body measurements of the young horses among the respective rearing facilities for testing young horses. The growth dynamics of young horses in the individual RFT considerably differed. The growth of young horses from the RFT Zeleznice was the most balanced showing no marked fluctuations. In the other rearing facilities the growth of the young horses fluctuated considerably in the course of the testing period. The growth of the young horses was retarded in the second half of the testing period in the rearing facilities Albertovec, Tlumacov and Luka-Tyn.
