It often appeared that North American cities would be unable to absorb all the new comers arriving in such large numbers. Presociological thinkers like Frederick Law Olmsted, the founder of the movement to build parks and recreation areas in cities, and Jacob Riis, an advocate of slum reform, urged the nation''s leaders to invest in improving the urban environment, building parks and beaches, and making better housing available to all. These reform efforts were greatly aided by sociologists who conducted empirical research on the social conditions in cities. In the early twentieth century, many sociologists lived in cities like Chicago that were characterized by rapid population growth and serious social problems. It seemed logical to use empirical research to construct theories about how cities grow and change in response to major social forces as well as more controlled urban planning.The founders of the Chicago school of sociology, Robert Park and Ernest Burgess, attempted to develop a dynamic model of the city, one that would account not only for the expans

It is easy to distinguish between prairie riparian forest and Black Hills forest—one is a broad-leaved forest of ash and cottonwood trees, the other is a coniferous forest of ponderosa pine and white spruce trees. One has kingbirds; the other juncos (birds with white outer tail feathers). The fact that ecological communities are indeed, recognizable clusters of species led some early ecologists, particularly those living in the beginning of the twentieth century, to claim that communities are highly integrated, precisely balanced assemblages. This claim harkens back to even earlier arguments about the existence of a balance of nature, where every species is there for a specific purpose, like a vital part in a complex machine. Such a belief would suggest that to remove any species, whether it be plant, bird, or insect, would somehow disrupt the balance, and the habitat would begin to deteriorate. Likewise, to add a species may be equally disruptive.?One of these pioneer ecologists was Frederick Clements, who studied ecology extensively throughout

Burning of fossil fuels, deforestation, urbanization, cultivation of rice and cattle, and the manufacture of chlorofluorocarbons (CFCs) for propellants and refrigerants are increasing the concentration of carbon dioxide, methane, nitrogen oxides, sulphur oxides, dust, and CFCs in the atmosphere. About 70 percent of the Sun''s energy passes through the atmosphere and strikes Earth''s surface. This radiation heats the surface of the land and ocean, and these surfaces then reradiate infrared radiation back into space. This allows Earth to avoid heating up too much. However, not all of the infrared radiation makes it into space; some is absorbed by gases in the atmosphere and is reradiated back to Earth''s surface. A greenhouse gas is one that absorbs infrared radiation and then reradiates some of this radiation back to Earth. Carbon dioxide, CFCs, methane, and nitrogen oxides are greenhouse gases. The natural greenhouse effect of our atmosphere is well established. In fact, without greenhouse gases in the atmosphere, scientists calculate that Earth would be about 33°C cooler than it currently is.?The current c

Extra Vitamin D and Calcium Aren’t Needed, Report SaysBy GINA KOLATAPublished: November 29, 2010The very high levels of vitamin D that are often recommended by doctors and testing laboratories — and can be achieved only by taking supplements — are unnecessary and could be harmful, an expert committee says. It also concludes that calcium supplements are not needed.Lawrence Lool/European Pressphoto AgencyA vitamin D pill.Readers'' CommentsShare your thoughts.Post a Comment ?Read All Comments (20) ?The group said most people have adequate amounts of vitamin D in their blood supplied by their diets and natural sources like sunshine, the committee says in a report that is to be released on Tuesday.“For most people, taking extra calcium and vitamin D supplements is not indicated,” said Dr. Clifford J. Rosen, a member of the panel and an osteoporosis expert at the Maine Medical Center Research Institute.Dr. J. Christopher Gallagher, director of the bone metabolism unit at the Creighton University School of Medicine in Omaha, Neb., agreed, adding, “The onus is on the people who propose extra calcium and vitamin D to show it is safe before they push it on people.”Over the past few years, the idea that nearly everyone needs extra calcium and vitamin D — especially vitamin D — has swept the nation.With calcium, adolescent girls may be the only group that is getting too little, the panel found. Older women, on the other hand, may take too much, putting themselves at risk for kidney stones. And there is evidence that excess cal

露天开采水力采矿法aqueousextractionmethods 17P

露天开采水力采矿法aqueousextractionmethods.pdf

1第七章 露天開採:水力採礦法 (Aqueous Extraction Methods) 7.1 方法分類 除了機械式採礦法外,另一次要的露天開採選擇方法為水力採礦法:依賴水或溶態液劑藉水力或溶解作用將礦物由地表物質中回收。水力法的種類包括了最古老以及最新進的採礦方式,但使用上不若機械開採廣泛 (不及露天採礦總量10%)。雖然水力採礦法的應用性有所限制,然而較低的相對作業成本 (指出水力法的相對成本僅為 5%或更低 ),致使它們仍受到青睞。 水力採礦可分為兩大類: 一、沖積採礦 (Placer Mining)-目的在回收沖積礦床中之重礦物,並利用水力來 開挖、運搬及 (或 )富集這些礦物。本採礦方式包括兩種方法:水沖採礦法 (Hydraulicking)及挖泥船法 (Dredging)。 二、溶液採礦 (Solution Mining):係利用水或溶劑將具溶解性的礦物由地表物質 中萃取出來。本採礦方式主要包括兩種方法:鑽孔萃取法 (Borehole Extraction)和浸漬法 (Leaching)。 除應用性受限制外,上述四種方法各具獨立的開發作業及循環順序。本章節就這四種採礦法的主要特性作探討,並簡扼地介紹在現今採礦上的限制。 7.2 沖積採礦 Placer Mining:水沖採礦法 Hydraulicking 沖積礦床為地質上具經濟價值之重礦物自然富集的堆積現象,較常見之礦物為金、鑽石、錫 (錫石, Cassiterite)、鈦 (金紅石, Rutile)、鉑、鎢 (鎢酸鈣, Scheelite)、鉻鐵礦、磁鐵礦及磷酸鹽 (可於似沖積礦床中發現 )等。沖積礦床依營力媒介可分為河流 (陸地碎屑 )、風力 (Eolian)、海流 (Marine)及冰川等類;若依位置則可分為殘留 (靜積, Elluvial)、台階 (bench 或山坡 (Hillside))、河流、海濱、埋藏 (Buried)及沙漠 (Desert)等。以商業性而言,河流與海流 (依營力區分 )及河流與海濱 (依位置區分 )等沖積礦床最為重要。 欲利用水力採礦之沖積礦床須具備下列條件: 21.礦經水壓作用 (或機械加上水力作用 )後易於崩解 2.有充份之水量供應所需之水壓 3.足夠之空間供廢棄物堆置 4.經濟礦物具高度富集,可用簡便之採礦過程予以分離 5.若利用水沖法,則有平緩而自然的地形傾斜角度以利運搬礦物 6.水資源供應及捨石棄置皆能符合環保法規 沖積採礦中以水沖採礦法及挖泥船法兩者具有較高產量。水沖採礦法係利用高壓之水柱直接底切似長堤狀的沖積礦床(如 圖 7- 1 ),當長堤狀礦床崩解後,這些已鬆動的物質 (礦物、砂及卵石 )部份與水形成泥漿而被沖至溜洗槽 (sluice,地面修改或金屬、木料製成的長槽 ),利用重力作用運搬至間隔減樣器 (Riffle Box)或更細緻的富集設備。水沖採礦法係利用水經由水管及高壓水槍,直接噴至長堤狀之沖積礦床。有種稱做 Intelligiant 的水槍 (如 圖 7- 2 ),採用彎曲狀水管之設計方式,可抵消水之反作用力,因而不必將之固定。 Intelligiant 水槍在垂直方向能擺動 1200,水平方向則可旋轉 3600。在操作上可將兩座或兩座以上之高壓噴嘴置於接近長堤狀位置,但須保持一段安全距離,而水槍彼此間距離亦需考慮開挖的區域能部份重疊且水柱與採掘面能保持特定角度。一般而言,堆積層之高度約為 15-50 英呎 (5-15 公尺 ),但有時可達 150-200 英呎,水槍之設計條件如下: 噴嘴直徑 1.5-6 in 水壓 100-450 ft 或 45-
