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.

Pengertian, Fungsi, dan Macam – Macam Satelit 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 Satelit, beberapa poin utama yang akan kami bahas adalah Pengertian Satelit, Jenis Satelit, Fungsi Satelit, dan Cara Kerja Satelit. Semoga dapat bermanfaat.

Pengertian Satelit

Satelit yaitu benda yang mengorbit benda lain dengan waktu perputaran serta revolusi tertentu. Sedangkan dalam kamus besar Bahasa Indonesia, satelit yaitu bintang siarah yang mengedari bintang siarah yang lebih besar, umpamanya bulan yang mengedari bumi. Satelit bisa melingkari planet lantaran adanya gaya gravitasi planet.

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. As i said before, early detection is the key of peritoneal mesothelioma treatment [] success since the cancer cell spread very fast.

Jenis serta Fungsi Satelit

Satelit Alami

Satelit alami yaitu satu diantara benda luar angkasa yang sudah ada (bukanlah buatan manusia) yang mengorbit sebuah planet. Satelit alami bumi yaitu bulan. Selama melingkari bumi, bulan alami tiga gerakan sekaligus, yakni perputaran, revolusi bulan melingkari bumi serta revolusi bulan melingkari matahari.

Perputaran adalah gerakan peruputaran bulan pada porosnya, saat perputaran bulan yaitu satu bulan (29hari), sedangkan revolusi adalah gerakan beredarnya bulan melingkari bumi. Akibatnya, apabila diliat dari bumi, bentuk bulan bakal berubah-ubah, hal semacam ini disebut dengan fase bulan. Dalam sekali revolusi, bulan alami beberapa fase salah satunya bulan baru – bulan sabit – bulan setengah – bulan bungkuk – bulan purnama – bulan bungkuk – bulan setengah – bulan sabit – bulan baru.

Tidak hanya berotasi serta berevolusi, bulan bersama bumi juga mengelilingi matahari. Waktu yang dibutuhkan bulan untuk mengelilingi matahari sama juga dengan waktu yang dibutuhkan bumi untuk mengelilingi matahari, yakni setahun. Bulan melingkari matahari sekali dalam satu tahun, sedangkan melingkari bumi 12 kali dalam satu tahun, hingga revolusi bulan kerapkali dijadikan penanggalan masehi/hijriah.

Mengenai fungsi satelit alami (bulan) diataranya adalah:

  • Secara tidak langsung membuat perlindungan untuk planet yang diorbitnya dari hantaman benda langit lain seperti komet serta asteroid
  • Bisa mengontrol kecepatan perputaran sebuah planet lantaran dampak gravitasional tidal wave
  • Menyeimbangkan rotasi siklus air laut yang mengakibatkan pasang surut air laut
  • Kurangi dampak yang ditimbulkan akibat radiasi sinar ultraviolet
  • Berikan penerangan saat malam hari

Contoh satelit alami yang lain salah satunya yaitu Callisto, Ganymede, serta Io yang mengorbit planer Jupiter, dan Titan yang mengorbit planet Saturnus.

Satelit Buatan

Satelit buatan yaitu satu diantara benda luar angkasa buatan manusia yang mengorbit sebuah planet yang dalam pembuatannya mempunyai jenis serta manfaat tertentu dengan maksud untuk kebutuhan manusia. Berikut ini adalah beberapa jenis satelit bersumber pada fungsinya:

  • Satelit navigasi, berperan untuk penerbangan serta pelayaran. Satelit ini bakal memberikan informasi posisi pesawat terbang serta kapal yang sedang dalam perjalanan.
  • Satelit geodesi, berperan untuk melakukan pemetaan bumi serta mendapatkan informasi mengenai grafitasi.
  • Satelit komunikasi berperan untuk komunikasi seperti radio, tv, serta telephone.
  • Satelit meteorologi, berperan untuk menyelidiki atmosfer bumi manfaat melakukan peramalan cuaca.
  • Satelit penelitian, berperan untuk menyelidiki tata surya serta alam semesta secara lebih bebas tanpa di pengaruhi oleh atmosfer. Satelit ini berupaya mendapatkan data-data mengenai matahari serta bintang-bintang lain untuk membuka rahasia alam semesta.
  • Satelit militer, berperan untuk kepentingan militer sebuah negara, umpamanya mengintai kekuatan senjata lawan.
  • Satelit survey sumber daya alam, berperan untuk memetakan serta menyelidiki sumber-sumber alam dibumi untuk kepentingan pertambangan, pertanian, perikanan serta lain-lain

Bersumber pada ketinggian garis edarnya, satelit dibedakan jadi tiga jenis, diantaranya:

  • Satelit LEO (Low Earh Orbit) yakni satelit yang bergaris edar rendah yakni di antara 500 km hingga 10. 000 km dari permukaan bumi. Waktu revolusi satelit ini yaitu 2 hingga 6 jam. Contoh satelit ini yaitu Iridium, Global Star, Elipsat, Odessey, serta Constellation
  • Satelit MEO (Medium Earth Orbit) yakni satelit yang bergaris edar menengah yakni diantaranya 10. 000 km hingga 20. 000 km. Waktu revolusi satelit ini antara 6 hingga 12 jam.
  • Satelit GEO (Geostatinonary Earth Global) yakni satelit yang ada pada orbit geostasioner yakni 36. 000 km dari permukaan bumi. Orbit stasioner yaitu orbit yang mengakibatkan waktu reovolusi satelit sama juga dengan perputaran bumi, yakni sehari. Contoh satelit ini yaitu satelit palapa serta intelsat.

Cara Kerja Satelit

Satelit yang mengelilingi bumi pada orbitnya bakal dikendalikan oleh Master Control Station di stasiun bumi. Pengendalian satelit yang ada puluhan ribu km. dari bumi memakai system automatis yang didasarkan atas dua system pengendalian, yakni Spin Stabillized Satellite serta Three Axiz Body Stabillized.

Spin Stabillized Satellite adalah cara pengendalian satelit dengan cara menggerakan body satelit secara berputar untuk menuju ke sebuah posisi tertentu yang diinginkan. Satelit secara teori bakal diam pada posisinya di orbit, pada kenyatannya bakal bergeser dari orbit yang sesungguhnya.

Three Axiz Body Stabillized adalah pengontrolan posisi satelit bersumber pada sumbu koordinal X, Y, serta Z. dari ketiga sumbu itu bakal dipetakan jadi posisi pitch, roll and yaw.

Kerja satelit terbagi dua, yakni langkah uplink serta downlink. Upulink yaitu transmisi yang di kirim dari planet bumi menuju satelit, sedangkan downlink yakni transmisi dari satelit ke stasiun bumi.
