Because we wanted to focus specifically on “speed” rather than general measures of quality, we custom-designed a scale to rank schools based on this highly desirable “fast factor.” Specifically, we researched each online college and asked ourselves the following questions: Does the school offer bachelor’s degrees that one could complete in less than four years? What about associate’s degrees in less than two years? Are there many short certificate options for students who want to quickly augment their skills in an established field? Are there “accelerated” degree paths and options for students who want to earn a combined bachelor’s/master’s degree? Does the school offer credit for life/work experience and past academic coursework in order to help students move ahead on their degree path? Does the school offer multiple course formats so that students have the option to start several times a year and/or to choose between classes of varying lengths? But don’t worry – we still considered graduation rate and tuition costs as well! We hope this has been helpful in providing information about fast online degrees from accredited colleges. There are many fast online degree programs available, and we encourage you to do a broad search to find the program that’s best for you.

Teori Asal Usul Kehidupan Selamat datang di Lahiya, situs (blog) sederhana yang berbagi ilmu dan pengetahuan dengan penuh keikhlasan. Dan, pada kesempatan kali ini, kami bakal sharing pengetahuan mengenai Teori Asal Usul Kehidupan. Darimanakah asal usul kehidupan makhluk hidup? Nah, penasaran bukan? So, keep your eyes open and stay close with your laptop, ya.

Malignant peritoneal mesothelioma is a rare type of mesothelioma which attacks the lining of abdomen also known as peritoneum. Malignant peritoneal mesothelioma (MPM) is a universally fatal disease affecting 20% to 30% of the mesothelioma cases. It's was first described by Miller and Wynn in the year 1908. According to the statistics, in the past two decades, the incidence of malignant peritoneal mesothelioma cancer has increased. Peritoneal mesothelioma affects the lining of the abdomen also known as peritoneum. The location of malignant cell is human's abdominal lining and because of that, MPM can sometimes known as abdominal mesothelioma. However, most common term used to describe this type of cancer is peritoneal mesothelioma. The main cause of MPM in humans is asbestos. Asbestos typically is the one of most commonly roofing materials since it is not only cheaper but is easy to fix on a roof. Asbestos exposure contributed to almost 70 to 80 percent of mesothelioma lung cancer. Humans come into contact with asbestos when they swallow or inhale the fibers. Asbestos inhalation may increase risk to develop asbestos related diseases, most importantly mesothelioma. Asbestos was completely banned in UK since it was recognized to be a serious health hazard, and it is now responsible for about 4000 deaths each year and many cases of serious disease. The people at increase risk of developing health asbestos related disease are those whose work brings them into direct contact with asbestos such as builders, heating engineers, roofers and demolition workers. In addition to mesothelioma, asbestos exposure will increase the risk of other health problems such as lung cancer, asbestosis (chronic lung ailment) and other type of cancer such as larynx and kidney cancer. Symptoms of Malignant Peritoneal Mesothelioma It can takes such a long time for cancer to develop the symptoms and sometimes may take up to 30 years, between exposure to asbestos and the start of the disease. Most common symptoms of the disease are abdominal pain, abdominal swelling, abnormal weight loss, anemia, easy fatigue, nausea and vomiting. Abdominal pain and swelling result from fluid accumulation in the abdominal cavity. Other than that, people can easily get fever when the disease starts to shows its symptoms. Among the symptoms stated above, abdominal pain is the most common reported initial symptoms of MPM. Unexplained night sweats and blood coagulation problems are less frequent symptoms occurring when the cancer develops. If the cancer cells spread to the other part of the body, the symptoms may lead to trouble swallowing or swelling of the neck and face. Diagnosis of Abdominal Mesothelioma It is very difficult to diagnose peritoneal mesothelioma since there is no defined system so far that can differentiate the stages of the development of cancerous tumor cells. If required, TNM staging system normally used to detect the cancer in stages. Other than that, Serum mesothelin-related protein (SMRP) may be a potentially useful serum marker used to diagnose and to follow-up the cancer progression. Computer tomography (CT) findings may be a useful tool in detection and characterization of peritoneal mass. Malignant Peritoneal Mesothelioma is a deadly neoplasm. MPM's diagnosis is difficult to perform since the symptoms will take a long time to show up. Early detection is the key in peritoneal mesothelioma treatment since the cancer cell normally spread very fast. Peritoneal Mesothelioma can be regarded as a very dangerous cancer among other cancer.However we can prevent this problems from occur to you and your family.

Sejak jaman dulu banyak orang yang mempertanyakan dari mana asal usul makhluk hidup, terlebih asal usul manusia. Lantaran rasa keingintahuan yang cukup besar teori asal usul kehidupan pun lahir karena pemikiran beberapa Ilmuwan. Teori itu tidak cuma satu sobat. Namun banyak teori yang lahir dari beberapa Ilmuwan dan beberapa diantaranya cukup populer. Nah, beberapa teori itu bakal kita bahas bersama pada hari ini. Selamat Membaca!

Teori Abiogenesis

Teori ini dicetuskan oleh Aristoteles (384-322 SM) yakni seorang pakar filsafat serta Ilmu dan pengetahuan Yunani Kuno. Menurut beberapa sumber teori ini adalah teori pertama yang mencetuskan asal usul kehidupan serta memberikan inspirasi pada ilmuwan-ilmuwan yang lain untuk mencetuskan teori baru. Jadi, menurut Aristoteles makhluk hidup berasal dari benda tidak hidup atau benda mati. Pada jamannya beberapa orang yakin kalau terjadinya makhluk hidup itu secara spontan atau terbentuk dengan sendirinya. Hingga teori ini dapat disebut juga generatio spontanea. Jadi menurut teori generatio spontanea, semua kehidupan yang berasal dari benda mati yakni:

Nah, nyatanya teman-teman ada ilmuwan lainnya yang sependapat dengan teori ini. Siapakah mereka? Ilmuwan pertama yakni John T. Needham, seorang ilmuwan dari Inggris. Bersumber pada teori ini Needham melakukan percobaan dengan merebus kaldu dalam wadah selama beberapa menit lantas dibiarkan dalam keadaan terbuka. Sesudah beberapa hari, air kaldu itu jadi keruh lantaran adanya mikroorganisme. Hingga Needham membuat sebuah rangkuman kalau tiap zat organik memiliki daya hidup yang bisa jadi makhluk hidup yang artinya bahwa mikroorganisme itu berasal dari air kaldu tadi.

Ilmuwan kedua yang sependapat dengan teori ini yakni Antonie van Leeuwenhoek, seorang penemu mikroskop cahaya. Dengan pertolongan mikroskopnya ini, Leeuwenhoek mencermati air rendaman jerami serta tampak adanya mikroorganisme, hingga rangkuman dari pengamatan ini kalau mikroorganisme berasal dari air.
Tidak hanya ada yang sependapat ada juga yang menentang teori ini sobat. Jadi, menurut beberapa pakar yang menentangnya apakah makhluk hidup itu muncul dari rendaman air jerami dan air kaldu serta air rendaman jerami itu yang menjadikan pembusukan pada air rendaman jerami dan air kaldu. Bersumber pada pernyataan ini beberapa pakar mulai giat untuk mengadakan uji coba hingga muncullah teori-teori baru.

Teori Biogenesis

Teori ini muncul dari bantahan beberapa pakar dengan teori abiogenesis Aristoteles. Jadi, menurut teori ini makhluk hidup berasal dari makhluk hidup. Teori ini lahir akibat uji coba dari tiga ilmuwan pendukung teori ini. Ilmuwan itu yakni Francesco Redi, Lazzaro Spallanzan serta Louis Pasteur.

Uji coba Francesco Redi (1626-1697)

Francesco Redi yaitu seorang ilmuwan berkebangsaan Italia yang menetang teori abiogenesis Aristoteles. Pada tahun 1668, Redi bereksperimen memakai 8 tabung yang dibagi jadi 2 bagian. Tabung-tabung itu diisi dengan daging ular, ikan, roti dicampur susu serta daging. Empat tabung pertama dibiarkan terbuka sedangkan empat tabung yang lain ditutup rapat. Setelah beberapa hari, pada tabung yang terbuka terdapat larva lalat.
Bersumber pada uji coba itu, Redi menyimpulkan kalau ulat bukanlah berasal dari daging namun berasal dari telur lalat yang ada pada daging serta menetas jadi larva lalat atau ulat. Uji coba ini ditentang oleh pendukung abiogenesis. Menurut mereka larva yang tidak tumbuh itu disebabkan karena tidak adanya udara atau zat hidup tidak bisa masuk hingga tidak adanya kehidupan. Bantahan itu ditanggap oleh Redi. Redi juga melakukan percobaan yang sama bedanya wadah itu ditutup dengan kain kasa hingga udara bisa masuk dan nyatanya didalam daging tetap tidak terdapat larva.

Uji coba Lazzaro Spallanzani (1729-1799)

Pada th. 1765, Spallanzani bereksperimen yang ditujukan untuk menyanggah teori dari Needham. Spallanzani bereksperimen dengan memanaskan 2 tabung kaldu hingga seluruh mikroorganisme di kaldu itu mati. Sesudah dingin, kaldu itu dibagi jadi 2 wadah. Wadah pertama berisi kaldu serta diletakkan pada keadaan terbuka. Sedangkan pada wadah kedua kaldu itu tertutup rapat. Nyatanya pada wadah pertama yang dalam keadaan terbuka terdapat adanya mikroorganisme sedangkan pada kedua yang tertutup tidak terdapat mikroorganisme.

Uji coba Louis Pasteur (1822-1895)

Uji coba Louis Pasteur memakai air kaldu rebusan daging sapi. Lantas air kaldu itu diletakkan pada labu yang berhubungan dengan udara luar serta dengan debu yang berasal dari udara.
Setelah beberapa hari, ditemukan adanya perkembangan mikroorganisme pada labu itu dalam jumlah yang banyak. Dari uji coba ini, Louis Pasteur menyimpulkan kalau mikroorganisme yang ada pada air kaldu itu berasal dari udara yang berdebu.

Nah, tidak lama lantas Pasteur bereksperimen memakai air kaldu lagi. Bedanya kali ini Pasteur memakai labu yang dilengkapi dengan tabung leher angsa. Labu yang berisi air kaldu itu dipanaskan sampai uap air keluar dari tabung yang berupa leher angsa. Pada tabung, akan terbentuk cairan yang berasal dari uap udara serta debu yang berasal dari luar serta tidak masuk kedalam labu, namun terjebak oleh air dalam tabung. Setelah beberapa hari, pada labu tidak ada mikroorganisme. Walau demikian bila air yang ada didalam tabung dimasukkan kedalam labu terdapat adanya mikroorganisme. Lewat uji coba ini, Pasteur menarik satu kesimpulan kalau mikroorganisme yang tumbuh didalam labu berasal dari udara serta tidak berasal dari air kaldu. Uji coba Pasteur sukses meruntuhkan teori abiogenesis Aristoteles.

Teori Kreatifitas (Teori Ciptaan Khusus)

Menurut teori ini, makhluk hidup di ciptakan oleh kemampuan supra natural secara sekaligus atau mungkin dengan interval waktu spesifik. Penciptaan tiap spesies atau makhluk hidup lainnya terjadi secara terpisah. Teori ini lahir tidak berdasarkan keilmuan ataupun sebuah uji coba.

Teori Kosmozoic

Teori ini didasarkan pada kehidupan diluar angkasa. Teori ini menyebutkan kalau spora yang datang dari luar angkasa yang berbentuk resisten meraih permukaan bumi. Kondisi luar angkasa yang pada saat itu dalam keadaan kekeringan, suhu yang dingin dan radiasi yang membahayakan memungkinkan tidak adanya kehidupan diluar angkasa. Sama dengan teori kreatifitas, teori ini tidak berdasarkan keilmuan atau sebuah uji coba.

Teori Evolusi Biokimia (Neoabiogenesis)

Teori ini dicetuskan oleh Alexander Oparin, pakar evolusi molekuler berkebangsaan Rusia. Bersumber pada pembicaraan Oparin di bukunya yang berjudul The Origin of Life (1936) kalau asal mula kehidupan terjadi bersamaan dengan evolusi terbentuknya bumi serta atmosfernya. Awalnya atmosfer bumi purba terdiri atas metana (CH4), ammonia (NH3), uap air (H2O) serta Hidrogen (H2). Lantaran adanya pemanasan serta energi alam berbentuk bebrapa cahaya kosmis serta halilintar, gas itu mengalami perubahan jadi molekul organic sederhana, semacam substansi asam amino.
