An Engineer Must Have These Qualities

An Engineer must have good facilities;

Gerekir.İngilizce know at least one foreign language may be next to it in another language, because now almost every college graduate oluyor.İspanyolca learned English at a variety of ways, Japanese, German, etc.
Speeches against the person have to be a beautiful diction bırakmalı.Diksiyon Training should be an impact to me.
AutoCAD, C, Java, Plc Programming, Matlab, SolidWorks, Office Word, Excel, Power Point-style programs, such as name, surname able to use. Of course, this need to choose according to your saydıklarımdan.Bir mechanical engineer, for example AutoCAD, SolidWorks and programs should be aware that office, but an electrical engineer, C, matlab, office programs, should know .. know the advantage of at least 2 programs ..
Should be a good environment.
Did they say what they say Prezantabıl that must be maintained.
Experience in their profession to have a good theoretical knowledge of everyday life at school able to pass gerekir.En importantly, I believe.

How obvious that those who have these jobs.
I would like to develop ourselves as an engineer have to ask how I'm the boss.

Phone allırken 3G compatible features would you like to pick up the phone do not have too much so-called wedge to get our phones istersiniz.Mühendis alırkende thinks sounds like the same employer.


Origami Yatch

The concept of a new candidate to the world of yachting. This opens up the boat to fold up the walls ...

The name of the Japanese art of paper folding origami yacht "Millennium Yacht Design Award" owner Designed by Fabio Federici.

This multi-purpose yacht sea with a different experience than ever before possible.

Unlike the classic yacht designs, more streamlined and simple, but long-line features a unique design yacht with origami.



Origami concept allows you to use as you want her yacht, equipped with a deck of a unique and very functional.



Origami is a combination of modern performance of a yacht'd iron, with a unique feature of the closure of the wings in the process of navigation to perform a quick and streamlined. Yacht, the walls of the wide range of fully opening the main bridge in the 360-degree view of the sea provides. It also remains the user to enjoy the scenery.
Origami concept of the yacht is still on paper, the estimated project cost will be around 6 million Euros.

The Biggest Ships

The biggest ships ever built four supertankers built in France at the end of the seventies, with a 555.000 DWT and a 414 meter length. They launched from the shipyard Chantiers de l'Atlantique in Saint Nazaire. The only larger ship was the jumboized "Knock Nevis" ex "Jahre Viking", ex "Seawise Giant", ex "Porthos," in 1981 (see entry in part 2). However, it had Batillus larger class of gross tonnage per ship, and it could be argued that they were in fact greater than the Knock Nevis is.






* Batillus, built in 1976, scrapped in 1985.
* Bellamya, built in 1976, scrapped in 1986.
* Pierre Guillaumat, built in 1977, scrapped in 1983.
* Prairial, built in 1979,
scrapped (Also known as "Hellas Fos" and "Sea Giant") in 2003

So here is "Pierre Guillaumat" - the largest ship ever built:

Akashi Kaikyo Bridge

The Akashi Kaikyo Bridge, popularly known as the Pearl Bridge, has the longest central span of suspension bridge. The central span is breathtaking 1991 meters (6532 ft) and thus is a truly wonderful Civil miracle. The hotel is located in Japan, the Akashi Kaikyo Bridge was busy in 1998 with the aim of linking the city of Kobe on the mainland to Honsho Iwaya on Awaji Island by crossing the street Akashi completed.

Construction Details

Central span - 1991 m (6532 ft)
Steel - 181 000 tonnes (It is said that a total of alternate cable could be used in this bridge include the world 7 times.)
Workers - 2 million
Time-10 years
Concrete - 1.4 million cubic meters

The bridge is using two lines, built the strech between two towers. The road is through other cables that support finally tied up with the main cable. Two large blocks anchor at both ends support of this gigantic structure.

Ilmu Tanah



Ilmu tanah adalah ilmu yang mempelajari seluk beluk tanah. Tanah adalah lapisan yang menyeliputi bumi antara litosfer (batuan yang membentuk kerak bumi) dan atmosfer. Tanah adalah tempat tumbuhnya tanaman dan mendukung hewan dan manusia.

Ilmu tanah adalah pengkajian terhadap tanah sebagai sumber daya alam. Dalam ilmu ini dipelajari berbagai aspek tentang tanah, seperti pembentukan, klasifikasi, pemetaan, berbagai karakteristik fisik, kimiawi, biologis, kesuburannya, sekaligus mengenai pemanfaatan dan pengelolaannya. Tanah adalah lapisan yang menyeliputi bumi antara litosfer (batuan yang membentuk kerak bumi) dan atmosfer. Tanah menjadi tempat tumbuh tumbuhan dan mendukung kehidupan hewan dan manusia.

Ilmu tanah dipelajari oleh berbagai bidang ilmu pengetahuan, seperti ilmu-ilmu keteknikan (rekayasa), agronomi/pertanian, kimia, geologi, geografi, ekologi, biologi (termasuk cabang-cabangnya), ilmu sanitasi, arkeologi, dan perencanaan wilayah. Akibat banyaknya pendekatan untuk mengkaji tanah, ilmu tanah bersifat multidisiplin dan memiliki sisi ilmu murni maupun ilmu terapan.

Ilmu tanah dibagi menjadi dua cabang utama: pedologi dan edafologi. Pedologi mempelajari tanah sebagai objek geologi. Edafologi, atau ilmu kesuburan tanah, mempelajari tanah sebagai benda pendukung kehidupan. Keduanya menggunakan alat-alat dan sering kali juga metodologi yang sama dalam mempelajari tanah, sehingga muncul pula disiplin ilmu seperti fisika tanah, kimia tanah, biologi tanah (atau ekologi tanah), serta ilmu konservasi tanah. Karena tanah juga memiliki aspek ketataruangan dan sipil, berkembang pula disiplin seperti mekanika tanah, pemetaan (kartografi), geodesi dan survai tanah, serta pedometrika atau pedostatistika. Penggunaan informatika juga melahirkan beberapa ilmu campuran seperti geomatika.

Tanah berasal dari pelapukan batuan dengan bantuan tanaman dan organisme, membentuk tubuh unik yang menyelaputi lapisan batuan. Proses pembentukan tanah dikenal sebagai pedogenesis. Proses yang unik ini membentuk tanah sebagai tubuh alam yang terdiri atas lapisan-lapisan atau disebut sebagai horizon. Setiap horizon dapat menceritakan mengenai asal dan proses-proses fisika, kimia dan biologi yang telah dilalui tubuh tanah tersebut.

Hans Jenny (1899-1992), seorang pakar tanah asal Swis yang bekerja di Amerika Serikat, dalam bukunya Factors of Soil Formation (1941) mengajukan konsep pembentukan tanah sebagai:

S = f(cl, o, r, p, t).

S adalah Soil (Tanah), cl = climate (iklim), o = organism, r = relief (topografi), p = parent material (bahan induk atau batuan), t = time (waktu).

Selain mempelajari faktor dan proses pembentukan tanah, ilmuwan tanah juga mempelajari sifat-sifat dan proses-proses fisika, kimia dan biologi dalam tanah. Sehingga lahirlah disiplin-disiplin

1. Pedologi
2. Fisika tanah
3. Kimia tanah
4. Biologi tanah
5. Konservasi tanah
6. Mekanika tanah
7. Pemetaan dan survey tanah
8. Pedometrika

Sejarah ilmu tanah di Indonesia

Ilmu tanah di Indonesia Pertama diajarkan di Fakultas Pertanian Universitas Indonesia (merupakan kelanjutan dari Lanbouw Hogeschool yang didirikan 1940) oleh staf pengajar dari Belanda Prof. Dr. Ir. F.A. van Baren (pakar agrogeologi dan mineralogi) dan Prof. Dr. H.J. Hardon (pakar ilmu tanah dan kesuburan tanah). Kemudian digantikan oleh Drs. F.F.F.E. van Rummelen dan Dr. J. van Schuylenborgh. Akibat nasionalisasi, sejak tahun 1957 digantikan oleh Drs. Manus dan Dr. Ir. Tan Kim Hong. Penelitian tanah di Indonesia mulai saat Indonesia masih dalam kekuasaan kolonial Belanda oleh Dr. E.C.Jul. Mohr (1873–1970). Dr. Mohr yang bertugas di Indonesia sebagai kepala Pusat Penelitian Tanah dan Agroklimat Laboratorium Voor Agrogeologie en Grond Onderzoek di Bogor telah menjalankan survai di Indonesia sejak tahun 1920. Ia menerbitkan bukunya tahun 1933:

* Mohr, E.C.J., 1933. De Bodem der Tropen in het Algemeen, en die van Nederlandsch-Indie in het Bijzonder. (Tanah-tanah di Daerah Tropis, dengan rujukan khusus di Hindia Belanda).

Buku tersebut memaparkan iklim dan komposisi tanah di berbagai tempat di Sumatera, Jawa, Bali, Lombok, Sumbawa, Timor, Papua, Maluku, Halmahera, Kalimantan dan Sulawesi, disempurnakan dan diedarkan kembali:

* Mohr, E.J.C., van Baren, F.A. and van Schuylenborgh, J., 1972. Tropical soils: a comprehensive study of their genesis. 3rd edition. Mouton – Ichtiar Baru – van Hoeve, The Hague.

Buku ini masih menjadi rujukan bagi pakar tanah di daerah tropis sampai sekarang.
