I-Osteoporosis yisifo esivamile lapho kwenzeka khona ukuphuka kwamathambo amaningi. Ngokuvamile kwenzeka emgogodleni, esinqeni, noma esihlakaleni futhi kungabangela ukulimala okukhulu noma ukufa. Ukusabalala kwe-osteoporosis e-United States kulinganiselwa ukuthi kuzokhula kusuka ezigidini eziyi-10 kuya ezingaphezu kwezigidi eziyi-14 ngo-2012 (ngokusekelwe kudatha ye-Census ka-2000). Njengoba ukuminyana kwamathambo kuphezulu esemncane, ingozi ye-osteoporosis iyancipha. Ukuhlanganyela emisebenzini yomzimba, njengemidlalo ehlelekile, kuvame ukuhlotshaniswa nokwanda kokuminyana kwamathambo.
Iphrojekthi yocwaningo ihlole imibuzo elandelayo: Ingabe ukuqina kwamathambo omuntu kuyashintsha ngokuhlanganyela emisebenzini yomzimba?
Lolu cwaningo luthole ubudlelwano obuhle phakathi komsebenzi womzimba wokuphila konke kanye nobuningi bamaminerali emathanjeni, okuphakamisa ukuthi abantu ababesebenza ngokomzimba impilo yabo yonke babenobuningi bamathambo obuphezulu kakhulu kunabantu ababenamazinga aphansi omsebenzi wokuphila konke. . Abantu abangazange basebenze ngokomzimba banamathuba amaningi okuba nobunzima bamathambo obuphansi (cishe u-10% wabantu bethu) kunabantu abanamazinga aphansi, aphakathi nendawo kanye naphezulu omsebenzi. Izifundo zikhombisile ukuthi njengoba amazinga omsebenzi ekhuphuka, amathuba okuba nobunzima bamathambo obujwayelekile noma obuphezulu ayanda.

Ukukhombisa ukuba khona kwamagciwane e-E. coli kusampula ngayinye yamanzi kuzokuvumela ukuthi uhlole ikhwalithi yamanzi asemabhodleleni kanye namanzi ampompi. Ama-Coliform ayizinto eziphilayo ezibonisa ukuthi kukhona amagciwane avela emthonjeni ofanayo obona ukuthi kukhona amagciwane amaningi. Akukhuthazwa ukuqapha amanye amagciwane ukuze kutholakale ukuthi kukhona amagciwane ayingozi ngenxa yendawo yawo ehlukile. (Byamukama noKanshiime et al., 1999). I-E. coli ingaphila emanzini okuphuza amasonto angu-4 kuya kwangu-12 kuye ngezimo zemvelo (Rice, Karlin, Allen, 2012). Izinhlobo eziyishumi ezahlukene zamanzi asemabhodleleni zizohlolwa ukuthi zinamagciwane e-E. coli, kanye namanzi ampompi avela emindenini eyishumi ehlukene. Uhlobo ngalunye lwamanzi asemabhodleleni kanye namanzi ampompi okusetshenziswa ekhaya luvezwa kathathu. Ngesikhathi esifanayo, inani elikhulu lamasampula amanzi lifakwa ku-incubator ukuze kuhlaziywe futhi kukhuthazwe ukukhula kwamagciwane. Lokhu kuzonquma ubumsulwa besampula ngayinye. Amasampula azobekwa ekamelweni elimnyama lapho kuzosetshenziswa khona ukukhanya kwe-UV ukukhanyisa amasampula ukuze kutholakale ukuthi kukhona i-E. coli. (Rice, Carlin, Allen, 2012).
Izintaba zaseSan Francisco eningizimu-ntshonalanga ye-Utah bezimbiwa kakhulu eminyakeni embalwa edlule. Ukumbiwa kugxile kakhulu kuma-quartz monzonites ase-Tertiary, ama-limestone asePaleozoic angenelelayo. Izinsiza ezibalulekile zenzeka emaphutheni amabili amakhulu acebile ngama-hydrothermal porphyry deposits, kodwa ukuhlangana kwala maphutha akukabhalwa kahle ngenxa yokungatholakali kahle kwamadwala. Besebenzisana nenkampani yezimayini yendawo, abafundi baseSouthern Utah baqale ukumaka kokuqala ukuthola nokuchaza lokhu kuwela kwamaphutha ngaphambi kokuqhubeka nokuhlola. Simaka indawo yama-fractures avele sisebenzisa idivayisi ye-Triton Juno GPS futhi salinganisa ubuningi bawo kanye nokuma kwawo kwama-fracture sisebenzisa ibhalansi nekhampasi yeBrenton. Imiphumela yemidwebo ye-rose, ama-stereograms namamephu ikhombisa ukuba khona kwama-fractures endaweni yokucwaninga. Ubuningi bama-fracture buyanda njengoba kusondela ama-fractures, ikakhulukazi kwenye yezindlela zokuqhekeka, futhi ngokuvamile ama-mineralization asendaweni emaphutheni. Sincoma ukuhlola okwengeziwe ngesimo sokumba i-core ezindaweni zama-fractures amaminerali ukuze kutholakale ukuthi kungenzeka yini ukuxhashazwa kwezomnotho.
Izintaba zaseHuahua eduze kwaseMinasville, e-Utah, bezilokhu zihlolwa ukuze kutholakale amaminerali eminyakeni embalwa edlule. Imithombo igxile emaphutheni e-porphyritic ashintshiwe ngamanzi, ngokuvamile lapho ama-quartz monzonites asezingeni eliphezulu angena khona ematsheni e-Paleozoic limestone. Ngaphezu kwe-Tertiary magmatism, izintaba zaseHuahua zibonisa ukugqama okuphawulekayo kwe-Late Cretaceous orogeny yaseSeville, zibeka amatshe asePaleozoic sedimentary phezu kwamatshe aseMiddle Cretaceous sedimentary. Ngesikhathi sephrojekthi yokudweba imephu yesakhiwo endaweni, itshe lesihlabathi laseNavajo phansi kweBlue Mountains Thrust latholakala ukuthi lenziwe i-hydrothermal silicification, okwenza lifane ne-quartzite. Lapho kuhlolisiswa kahle, kwatholakala amanye amaminerali ase-hydrothermal. Le miphumela ishintsha ukugxila kocwaningo kusuka ekubhaleni i-structural geology kuya ekubhaleni izinguquko ezihlukile ze-hydrothermal ematsheni esihlabathi aseNavajo.
Lolu cwaningo luhlanganisa izindlela ezilandelayo. Endaweni yezintaba eziluhlaza okwesibhakabhaka, kuseshwa amatshe aseduze nesikhathi sokukhukhuleka kwenkathi yeSevier. Amasampula etshe lesihlabathi leJurassic Navajo aqoqwa futhi kwenziwa izingxenye ezincane ukuze kuhlaziywe okuqukethwe yinsimbi edwaleni. Amasampula atholakale eduze kwengxenye esempumalanga yezintaba eziluhlaza okwesibhakabhaka aqukethe i-quartz, i-hematite, nezinye izinsimbi ezincane. Ukumbiwa kwamaminerali akucebile kakhulu, kodwa ngokujula okwandayo, amatshe amaminerali emithanjeni angaba maningi kakhulu. Ukuhlaziywa okwengeziwe, njengokuhlaziywa kwamandla adonsela phansi kanye nedatha eyinhloko, kuyadingeka ukuze kunqunywe inani lokumbiwa kwamaminerali.

I-Book Rocks eningizimu-mpumalanga ye-Utah ibilokhu iyindawo yokudlala yezizukulwane zezazi ze-geology ezidumile. Iningi lezindawo ezingaphandle liye lafundwa kabanzi ngoba zifana kahle nezindawo eziningi zokugcina amanzi ezingaphansi komhlaba, ezisogwini kanye nomhlaba. Kodwa-ke, izindawo eziningi ezingaphandle zinikeza izithombe ze-2D kuphela futhi azikwazi ukuchaza ngokugcwele isakhiwo se-stratigraphic kanye nokungafani kwezindawo. Kulesi sifundo, sethula idatha evela kuma-cores amasha avela ku-Upper Cretaceous Price Canyon, iCastlegate kanye ne-Blackhawk Formations. Lolu cwaningo, oluyingxenye yokubambisana phakathi kwe-University of Southern Utah kanye ne-University of Montana, lugxile ekuchazeni isakhiwo se-subsurface se-3D kanye nokungafani kwezindawo ezingaphansi komhlaba zalezi zakhiwo ezivela ochungechungeni lwezindawo ezingaphansi komhlaba. Izindawo ezingaphansi komhlaba ezichazwe lapha ziqukethe inani elikhulu lezindawo ezingaphansi komhlaba ezihlotshaniswa nezindawo ezisogwini kanye nezisogwini. Amadwala ahlotshaniswa nezindawo ze-Blackhawk Formation aqukethe amabala avelele esihlabathi esimhlophe, esinohlamvu oluhle, esinombhede kanye nesinombhede onqamulelayo esinamatshe amancane ahlukaniswe ngamatshe odaka ampunga kuya kumnyama asontekile futhi anemibhede, amatshe e-silt ampunga, kanye nemithungo yamalahle.
Sichaza la maphakethe njengokumelela ushintsho oluvela endaweni ehleliwe yolwandle/yase-deltaic elawulwa yizinqubo ze-fluvial ukuya endaweni egcwele i-fluvial ngesikhathi seCastlegate. Ubukhulu bomzimba wesihlabathi (usayizi wesiteshi) buyahlukahluka ngokuhamba kwesikhathi, neziteshi eziningi ezihlangana kaningi esikhaleni seCastlegate. Ucwaningo luzoqhubeka, luqale ngokuhlaziywa okuhlelekile kwama-core asele bese luphela ngochungechunge lwamaphrojekthi abafundi ngokuhlaziywa kwe-facies kanye nokumodelwa kwe-facies ye-3D.
Abacwaningi bangaphambilini baphakamise indlela yokwakheka kwe-tectonics enamapuleti amabili ku-Mars ngokusekelwe ekushintsheni kwesandla sobunxele kwe-Mariner Valley. Sisebenzisa izindlela ezifana nesithombe sesathelayithi se-Thermal Imaging System (THEMIS), isithombe sesathelayithi se-High Resolution Science Imaging Experiment (HiRISE), amamodeli okuphakama kwedijithali, kanye nesofthiwe esebenzisana nayo njenge-Google Mars, sithole ezinye izici zobuso obukhulu eziseduze e-Marineris Valley. . kanye ne-Tarsis Ryze. Nakuba ukunyakaza kwe-tectonic kuhamba kancane kakhulu ku-Mars, singaqhathanisa imigqa, ama-fold, kanye nama-conjugate junctions e-Mars anezakhiwo ezifanayo eMhlabeni ukuchaza imingcele yamapuleti engaba khona. Isibonelo, isethi yemigqa ye-NE trendlines ene-side strike-slip displacement ebalulekile kanye nama-junctions ahlobene enyakatho-mpumalanga ye-Tarsch Rise ingase ivumelane nokwakheka phakathi kwamapuleti amabili. Ukubuka kwethu kwenza kube nokwenzeka ukuhlonza okungenani imiphetho emibili eyengeziwe yamapuleti angase abe khona kulesi sifunda. Siphakamisa imodeli ye-tectonic ekhombisa ukunyakaza okuhlobene eceleni kwemingcele yamapuleti ekhombisa uhlelo lwamapuleti amaningi ku-Mars.
Esigabeni sesimo sezulu saseKöppen, isimo sezulu esomile/esomile kancane noma isimo sezulu B sichazwa njengesimo sezulu lapho ukuhwamuka kudlula khona imvula. Kodwa-ke, akazange anikeze inqubo yokubala esemthethweni. Siphakamisa igama elisha, imvula engaba khona ngokweqile (i-PEP), njengendlela elula yokuchaza izindawo ezomile nezinomswakama. Inani le-PEP lilingana nenani langempela lemvula ngaphandle kwe-evapotranspiration engaba khona (i-POTET). Uma inani le-PEP lihle, isimo sezulu sesiteshi singu-A, C, noma u-D, kodwa uma inani le-PEP lihle, isimo sezulu sesiteshi singu-B. Ukusebenzisa inani le-PEP kunikeza isiteshi ngasinye inani elihle noma elibi elingadwetshwa, futhi i-null contour ichaza umngcele omanzi owomile kancane.
I-Kaiparowitz Formation, etholakala eningizimu-maphakathi ne-Utah, iphethe irekhodi le-Late Cretaceous floodplain eyaphuma e-La Ramedia Highlands yaya e-Western Inland Waterway. Ukwakheka kucebile ngama-fossil futhi kuqukethe izitshalo zasendulo, izilwane ezingenamgogodla, izinhlanzi, izilwane ezihlala emanzini nasemanzini, izilwane ezihuquzelayo nezilwane ezincelisayo, eziningi zazo ezintsha kwisayensi. Ukuchazwa okukhulu kwalokhu kwakheka kuye kwachazwa ngaphambilini njengezindawo zamanzi nezikhukhula eziqukethe izindawo ezahlukene zamanzi namachibi. Lolu cwaningo lunikeza incazelo eningiliziwe ye-sedimentological ye-quarry encane yesitshalo futhi luchaza izimo zokubekwa.
