The Geochemical Atlas of Slovak Republic (49,036 km2) at a scale of 1 : 1,000,000 was compiled during 1991–1995 together with maps of associated geochemical and ecological features at a scale of 1 :200,000. Investigations were aimed at the evaluation of concentrations and distributions of Al, As, Ba, Be, Ca, Ce, Co, Cd, Cs, Cr, Cu, Fe, Ga, Hg, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Rb, Sb, Se, Sn, Sr, Th, U, V, W, Y, Zn, Zr in groundwater (16,359 samples), stream sediments (24,422 samples), rocks (3839 samples), soils (9892 samples from 4946 profiles; A and C horizons of each profile were sampled) and forest biomass (the foliage of the forest tree species from 3063 plots was sampled). In groundwater field measurements of temperature, pH, conductivity, dissolved O2, acidity, alkalinity were done. The evaluation was oriented to the natural radioactivity of the Slovak territory as follows: rocks (K, U, Th, Utot and dose rate, 15,573 reference spectrometric points), radon risk and water (Unat, 226Ra, 222Rn; 5271 samples). The main objective of the Geochemical Atlas was to construct single-component maps showing concentrations of chemical elements, compounds and measured parameters in the researched media of Slovakia at a scale of 1 : 1,000.000 and to create interactive databases of chemical composition and/or measured parameters of groundwater, biomass, rocks, soils, stream sediments and natural radioactivity, for the entire territory of the Slovak Republic. The single-component maps are not constructed in the part ‘Rocks’, where all the main rocks types of Slovakia are presented in the ‘Map of lithogeochemical rock types of Slovakia at a scale of 1: 500,000’. The edition of six atlases has been planned. In 1997 the first three atlases will appear (Groundwater, Biomass, Natural Radioactivity). Publishing of last three atlases (Rocks, Soils, Stream Sediments) is planned for 1998. Since the analytical works on stream sediments were finished during 1997, it was not possible to present here the results of that part of the Geochemical Atlas.  相似文献

The purpose of this study was to provide baseline data on floodplain forest structure, composition, and function that would be needed to predict and monitor the consequences of a proposed stream restoration project. This project would involve the “dechannelization” of Stokes Creek, a stream in western Tennessee that was channelized and leveed in the first half of the 1900s. To this end, we collected data on surface hydrology, soil redox potential (Eh), and the structure and composition of the floodplain vegetation of Stokes Creek. To place our findings into a regional context, we also collected comparable vegetation data from plots located along a nonchannelized stream reach of the Wolf River near Moscow, Tennessee. While hydrologic fluctuations of floodplain sites were synchronous with river dynamics for the Wolf River, the hydrology of floodplain sites at Stokes Creek was constrained by the influence of beaver dams, backflooding, and ponding of overland flow behind levees. Consequently, composition of the forest overstory, understory, and herbaceous strata was significantly different between the two sites. For example, Stokes Creek had a noticeable lack of cypress and tupelo sites, and a greater abundance of red maple. Analyses of size-class structure and woody debris quantity reinforced the existing differences between the more natural and human-impacted systems. While the current hydrology apparently has a negative affect on bottomland hardwoods, scattered regeneration stems and soil redox measurements indicate that a dechannelization effort that yielded lower water tables in the Stokes Creek floodplain potentially could increase bottomland hardwood establishment.

Abstract

</p>Gamepads and joysticks have the potential to improve spatial navigation in virtual globes, block diagrams and 2D maps. Digital school atlases, in particular, can become more engaging if support for gamepads and joysticks is added, as children and adolescents are very proficient at using these devices. The fusion of gaming devices and interactive school atlases offers interesting new use cases: teachers can control a digital wall map with a remote-control gamepad while lecturing from the front of the classroom, or students can explore maps on their personal computers using an enticing way to interact. This paper presents these use cases, the characteristics of the most common gaming devices, and discusses spatial navigation with gamepads and joysticks for globes, block diagrams and 2D maps. The ideas presented originated from the ongoing development of a new, interactive version of the Swiss World Atlas for schools.  <a href="relate_search.aspx?pcid=E62459D214FD64A3C8082E4ED1ABABED5711027BBBDDD35B&cid=A41A70F4AB56AB1B&aid=5A172168B32099AE544AB8BD3EC6ADF4&language=1" target="_blank">相似文献</a>    </div> <div></div> <div class="clear"></div> </div> <div class="clear"></div> </div> <div> <div class="search_article_pager"> <a href="search.aspx?start=0&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx">[首页]</a> <a href="search.aspx?start=20&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx">« 上一页</a> <a href="search.aspx?start=0&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[1]</a> <a href="search.aspx?start=10&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[2]</a> <a href="search.aspx?start=20&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[3]</a> <b>4</b> <a href="search.aspx?start=40&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[5]</a> <a href="search.aspx?start=50&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[6]</a> <a href="search.aspx?start=60&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[7]</a> <a href="search.aspx?start=70&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[8]</a> <a href="search.aspx?start=80&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[9]</a> <a href="search.aspx?start=90&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[10]</a> <a href="search.aspx?start=100&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx" >[11]</a> <a href="search.aspx?start=40&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx">下一页 »</a> <a href="search.aspx?start=230&q=photomap atlas&field=key_word&subject=astronomy_earth_science&major=chx">末  页»</a> </div> <div class="clear"></div> </div> </div> </div> </div> </div> </td> </tr> </table> </td> </tr> </table> <table width="870" border="0" align="center" cellpadding="0" cellspacing="0"> <tr> <td height="40" align="center" class="fo2"> <a href="#" onClick="this.style.behavior='url(#default#homepage)';this.setHomePage('http://td.alljournals.com.cn')">设为首页</a> <span class="STYLE1">|</span> <a href="http://www.alljournals.cn/note.aspx">免责声明</a> <span class="STYLE1">|</span> <a href="http://www.e-tiller.com"><u>关于勤云</u></a> <span class="STYLE1">|</span> <a href="javascript:window.external.addFavorite('http://td.alljournals.com.cn','期刊界 All Journals---天文学、地球科学')">加入收藏</a></td> </tr> <tr> <td align="center" class="fo3"> <p align="center"> Copyright<span lang="en">©<a href="http://www.e-tiller.com"><u>北京勤云科技发展有限公司</u></a>  京ICP备09084417号    </span></p> </td> </tr> </table> </div> <form id="ReSearchForm" name="ReSearchForm" method="get" action="search.aspx"> <input type="hidden" name="result_field" id="result_field2"> <input type="hidden" name="result_q" id="result_q2"> <input type="hidden" name="StartYear" id="StartYear2"> <input type="hidden" name="EndYear" id="EndYear2"> <input type="hidden" name="q" value="photomap atlas"> <input type="hidden" name="field" value="en_key_word"> <input type="hidden" name="subject" id="subject2" value="astronomy_earth_science"> <input type="hidden" name="major" id="major2" value="chx"> <input type="hidden" name="is_oa" id="is_oa2" value="10"> </form> </body> </html> <script language='javascript'> $(document).ready( function() { $("#OrderByField option[value='relate']").attr("selected",true); }); function ChangeOrderBy(strOrderBy){ location.href="http://td.alljournals.cn/search.aspx?field=key_word&major=chx&q=photomap+atlas&start=30&subject=astronomy_earth_science&OrderByField="+strOrderBy; } function SearchBySubject(strValue){ $("#subject2").attr("value",strValue); document.forms["ReSearchForm"].submit(); } function SearchByMajor(strValue){ $("#major2").attr("value",strValue); document.forms["ReSearchForm"].submit(); } function SearchByAccess(strValue){ $("#is_oa2").attr("value",strValue); document.forms["ReSearchForm"].submit(); } function SubmitSearch(strFiledName,strFieldValue){ $("#result_field2").attr("value",strFiledName); $("#result_q2").attr("value",strFieldValue); document.forms["ReSearchForm"].submit(); } function YearSearch(strFieldValue){ $("#StartYear2").attr("value",strFieldValue); $("#EndYear2").attr("value",""); document.forms["ReSearchForm"].submit(); } </script>
