A total of 46 Swiss alpine does were examined. We analysed the composition of the milk and evaluated the body condition of the animals (BCS: 0.5 to 4.5 scale) on the same day in the last third of lactation. Goats were grouped according to their body condition for statistical calculations. We found that there was a statistically detectable relationship between body condition and milk composition of the goats. Together with the increase of BCS, the fat, protein and mineral contents in the milk increased as well. Significantly more fat, protein and mineral contents were found in the milk (6.01%;3.55%; 0,98%) in case of the well-conditioned (BCS 3.5) animals than in the thin ones (BCS 1.5-2) (4.56%, 3.11%, 0.77%) (P<5%). The concentration of milk sugar was similar between thin and better conditioned groups of animals, so the body condition did not affect these values. The importance of our study is that, the high fat and protein content of milk increases the yield of dairy products. If the animals can produce milk that has higher fat and protein content, than we can produce more dairy products that will bring more economic benefits. The aim of our study was to evaluate the effects of body condition on milk yield and quality (milk composition) in dairy goats.
The rural development grants - among others - help to promote the competitiveness of the agricultural activities. Plantations take great interest in the southeastern part of Hungary. Farmers need to make soil tests before plantation of fruit and grape. We investigated the distribution of the main physical characteristics in this area. For the establishment of vineyards, the areas were adequate according to the pH, and salt content. The results of the soil tests show some strong relationships between the determined physical parameters.
Advancements in computer technology that have occurred in recent decades have enabled an intensive development in cartographic methods for direct representation of phenomena dynamics. Even with the appearance of ever more advanced technical solutions, the theoretical basis still needs supplementing. The previous cartographic literature emphasises the importance of congruence and isomorphism principles preservation that aims at increasing the effectiveness of dynamic displays. Nevertheless, it is frequently the case that discontinuous phenomena are depicted with the use of smooth transitions. For this reason, it is vital that experimental research should lead to defining which representation methods are appropriate for a given type of content. Our study was focused on the cartographic design of scene transitions in animated maps. Two main conclusions of the research indicate that 1) mode of transition influences the interpretation of the content of cartographic animation depicting discrete changes, 2) maps executed in a smooth mode demonstrate lower effectiveness when compared with animations using an abrupt and abrupt with decay effect transitions.
The author discusses a phenomenon of putting the works of military cartography on medals cast in the 17th century. The analysis focused on a medal presented to Krzysztof Arciszewski (1592-1656) by the Dutch West India Company in 1637. The obverse of this medal features two cartographic images depicting the siege of the Arraial Velho do Bom Jesus fortress (1635) and the battle between Camarigibi and Porto Calvo (1636). They were patterned after two manuscript maps. The maps were made by Arciszewski and attached to a memorandum written and sent to the management of the West India Company on 13 June 1633. They were engraved and published in print only around 1644. The plan of the battle that took place on 18 January 1636 indicates that the engraver (author unknown) used not only the manuscript version but also the medal. The example of the medal minted in 1637 confirms the credibility of cartographic representations featured on numismatic items. It should, naturally, be borne in mind that such representations must have been simplified due to the very nature of the means. Nevertheless, should there be no proper manuscript pattern, such objects may be used successfully as valuable cartographic sources.
Nigeria has a vast array of both natural and cultural tourist attractions. The country’s tourism industry, however, remains grossly underdeveloped, and the tourism resources are largely untapped. Hence, the tourism sector of the economy is yet to contribute significantly to the national Gross Domestic Product (GDP). One major factor that is responsible for the nation’s current lacklustre performance of the tourism sector is the poor state of tourism packaging and promotion, which, amongst other things is caused by the lack of appropriate tourist maps. Tourism mapping is a key component of tourism planning, development, promotion and management. For Nigeria to drastically and significantly improve the fortunes of her tourism sector, the production, circulation and use of accurate, current and comprehensive tourist maps and atlases must be vigorously pursued. To ensure sustainable tourism mapping and in line with global best practices, the country needs to adopt a Geoinformation technology-based, Internet-compatible multimedia cartographic approach. The author of this paper, therefore, examines the current state of tourism industry and tourism mapping in Nigeria. Some of the hiccups to tourism mapping in the country are identified. The implications of the present poor state of tourism mapping on tourism planning, development, promotion and management in the country are briefly considered. The author makes a strong case for the adoption of a multimedia cartographic approach to tourism mapping in Nigeria. A case of mapping wildlife parks in Nigeria is presented to demonstrate the prospects of effective multimedia tourism mapping of the country. Furthermore, the author identifies and discusses various existing resources in the country that could be harnessed for efficient and sustainable production, distribution and use of multimedia tourist maps/atlases, using Geographical Information Technologies (GIT). Some potential challenges to effective GIT-based tourism mapping in the country as well as how such challenges could be overcome, are equally discussed. Similarly, a model for Web-based, multimedia tourism mapping using GIT is presented. With clear vision, the right policy instrument, mandate, legislation, funding and coordination in place, the current challenges to effective and sustainable tourism mapping in Nigeria can easily be surmounted.
The article presents the person and works of Georgy Voronoi (1868-1908), the inventor of an original method of diagrams, a student of the famous mathematician Andrey Markov. Georgy Voronoi graduated from the Department of Physics and Mathematics at the University of St. Petersburg, and subsequently worked as a professor of mathematics at the Imperial University of Warsaw. One of his students was the future outstanding Polish mathematician Wacław Sierpiński. In his brief lifetime G. Voronoi published several important scientific articles on number theory. In an almost 100 page paper in French published in 1908 he described a method of diagrams, or polygons, which became known as the method of Voronoi diagrams. In the digital age this method and its modifications found new applications. The entry “Voronoi” is getting more popular on the Internet, and the method of Voronoi diagrams and its modifications are widely described in handbooks and scientific articles. The article presents application of the method in the most popular computer programs from the Geographic Information System (GIS) group and presents examples of its usage in research on geographic space in various scientific disciplines.
Global warming and soil salinity are major constraints threat speared of Mediterranean endogenous flora, however little is known about the effect of these phenomena on seed germination patterns, particularly in Algeria. Germination test under laboratory controlled conditions had been carried out using seeds of Marrubium vulgare, Sideritis incana and Stachys ocymastrum. Seeds were submitted at temperatures of 5, 10, 15, 20, 25, 30 and 35 °C, after that and within optimum temperatures, various sodium chloride (NaCl) concentrations of 0, 34, 68, 102 and 136 mM were set to evaluated salinity effect. Germination was more satisfactory on temperatures ranged between 15 and 25 °C. Whereas, increased or decreased temperatures from the optimum bring to germination fall. High seed germination capacity had been showed on non-saline solution. While, germination had depressed by enhanced NaCl solution up to 136 Mm in which Final Germination Percentage are either significantly decreased (for S. ocymastrum seeds 18% germination) or absolutely inhibited (for M. vulgare and S. incana seeds), as well Initial Germination Day are delayed. Overall, data showed that germination patterns response varies among species, given that seed germination is remarkably limited by extremes temperatures and salinity.
Built-up area is a particularly important element of the content of topographic maps. Its presentation changes significantly when map scales are reduced, due to both conceptual and graphic generalization. What is more, historically, changes in the depiction of built-up area were consequences of changes in the intended use of topographic maps, development of technology and changes in the cultural landscape, of which the built-up area is an important component.1
The authors describe the method of presentation of built-up areas on six Polish topographic maps or series of maps. The above-mentioned maps include the following:
– Topograficzna Karta Królestwa Polskiego (Topographic Map of the Polish Kingdom) at the scale of 1:126,000 developed in 1822–1843;
– topographic maps of the Polish Military Geographical Institute (MGI) at the scales of 1:25,000 and 1:100,000, published in 1930s;
– a series of military maps (or military-civilian maps) at the scales of 1:10,000, 1:25,000, 1:50,000 and 1:100,000, developed in 1956–1989, in accordance with the instruction for developing Soviet maps;
– a series of civilian maps at the scales of 1:10,000, 1:25,000, 1:50,000 and 1:100,000 developed after 1995.
The basis for a quantitative comparison of the content of the maps was the number of categories of objects (identifications) which constitute part of built-up area and are presented on individual maps as symbols, as well as the number of characteristics represented by these symbols. These characteristics are divided into two basic types: functional characteristics and physiognomic characteristics.
The analysis shows that military maps issued after the Second World War differ from the civilian maps, as they contain a much larger share of physiognomic characteristics, which is caused mainly from the fact that the vast majority of military maps distinguish between wooden and brick buildings. This difference was to large extent already noticeable among the oldest of the analysed maps – the Quartermaster’s Map and nineteenth-century Russian maps, which were partly modelled on the Quartermaster’s Map, and later also Soviet maps. Due to political reasons, the model of these Soviet maps was later adopted for the development of post-war Polish military maps. Out of all maps drawn up by military services, the inter-war MGI map serves special attention, as it was modelled on German maps. The main difference between military and civilian maps is foremost the fact that civilian maps include more functional characteristics of buildings and take into consideration new physiognomic characteristics related to residential development (compact, dense, multifamily dwellings, single family dwellings).
The analysed maps include not only the characteristics of buildings and built-up area, but also information on the features of the town – population size, number of village houses and the administrative function.
The paper discusses selected maps of rock strata which exemplify the evolution stages of presentation methods of cartographic data concerning the geological structure of selected countries (France, Great Britain and Germany) which in the first half of the nineteenth century constituted the leaders of the field. The results of geologists’ work are used to present the content of maps, provide explanations and showcase the methods and techniques chosen by the maps’ creators. The analysed maps are accompanied by geological writings which contain descriptions of the chronological order within rock formations and strata defined on the basis of fossils, methods of recreating the geological history of individual regions, and attempts of compiling the acquired knowledge and using it to describe larger areas. The author discusses also two maps of Europe published in the mid-nineteenth century, which are the result of cooperation and research achievements of geologists from different countries.
The aim of the article is to present different relief visualization techniques created using only free and open source GIS tools, such as QGIS and RVT. The criteria for selection of these techniques are that they should be, on the one hand, simple and fast for implementation and on the other suitable for multiple visualization purposes. Here we present several techniques which combine hillshade with other relief data layers derived from DEM and an assessment of advantages and disadvantages of their visualization.
