Rotogravure

Rotogravure (roto or gravure for short) is a type of intaglio printing process, in that it involves etching the image onto an image carrier. In gravure printing, the image is stamped onto a copper cylinder because, like offset and flexography, it uses a rotary printing press. The vast mass of gravure presses print on reels of paper, quite than sheets of paper. Sheetfed gravure is a modest, specialty market. Rotary gravure presses are the best and widest presses in operation, printing everything from narrow labels to 12-feet-wide rolls of vinyl flooring. Additional operations may be in-line with a gravure press, such as saddle stitching services for magazine/brochure work.

Cricket ball

Cricket balls are made from a core of cork, which is coated with tightly wound string, and covered by a leather case with a slightly raised sewn seam. The covering is constructed of four piece of leather shaped similar to the peel of a quartered orange, but one hemisphere is rotated by 90 degrees with respect to the other. The "equator" of the ball is stitch with string to form the seam, with a total of six rows of stitches. The remaining two join connecting with the leather pieces are left unstitched.

For men's cricket, the ball must weigh between 5.5 and 5.75 ounces (155.9 and 163.0 g) and determine between 8 13/16 and 9 in (224 and 229 mm) in circumference. Balls used in women's and youth matches are a little smaller.

Journalism

Journalism is a concrete, professionally oriented major that involves gathering, interpreting, distilling, and other reporting information to the general audiences through a variety of media means. Journalism majors learn about every possible kind of Journalism (including magazine, newspaper, online journalism, photojournalism, broadcast journalism, and public relations).

That's not all, though. In addition to dedicated training in writing, editing, and reporting, Journalism wants a working knowledge of history, culture, and current events. You'll more than likely be required to take up a broad range of courses that runs the range from statistics to the hard sciences to economics to history. There would also be a lot of haughty talk about professional ethics and civic responsibility too - and you'll be tested on it. To top it all off, you'll perhaps work on the university newspaper or radio station, or possibly complete an internship with a magazine or a mass media conglomerate.

Transparent Tables

SAP uses another concept called transparent tables, which are SAP database tables that contain only data at runtime. When a table is activated in the ABAP/4 Data Dictionary, a transparent table is created automatically in the database. This transparent table encloses the same name as your database table contained in the ABAP/4 Dictionary. Each of its fields contains the same names as their database counterparts though the sequence of the fields might get varied. This unstable field sequence makes it possible to insert new fields into the table without having to convert it, all of which pays a way for more rapid access to data during runtime.
