... There are two ways to create menus: there's the easy way, and there's the hard way. ... So, if we wanted to create a standard File menu , with the options Open , Save , and Quit , the code would look something like: file_ menu = gtk_ menu _new (); /* Don't need to show menus */ /* Create the menu items */ open_ item = gtk_ menu _ item _new_with_label ( Open ); save_ item = gtk_ menu _ item _new_with_label ( Save ); quit_ item = gtk_ menu _ ... Create a menu item using gtk_menu_item_new(...

... Every year, more and more journals are switching from mailing paper copies to subscribers to putting material on the Internet either for free or via password-protected access. The primary driving force behind this is simple economics: the cost of publishing material online is a minuscule fraction of the expense of printing articles in a paper journal and mailing it. The majority of people over 40 greeted the advent of online journals with much sadness and even some derision. ...

The above process keeps the # of protons and the # of neutrons in the early Universe constant. This is extremely important and will result in a testable prediction later. Remember, a free neutron (one that is not bound in an atomic nucleus) will decay into a proton + electron (+ anti-neutrino) in about 900 seconds. ... During this epoch, the proton-to-neutron ratio is 1.0 . ... The Universe consists of protons, neutrons and electrons plus a photon background and a neutrino background. ...
