This working paper analyzes the energy embodied in agricultural inputs from a historical perspective. Consequently, to produce a solidified iron ore having a Fe2O3 crystalline phase without a heterogeneous element, while increasing its crushing efficiency, the optimum cooling rate was confirmed to be 20 ☌/min. Therefore,when the cooling rate was increased from 5 to 953 ☌/min, the Vickers hardness and flexural strength decreased by about 41% and 59%, respectively. When the cooling rate was increased above 27 ☌/min, only minor exotherms were observed. Thermal analysis showed that crystallization temperature decreased from 1390 to 1357 ☌ as the cooling rate was increased from 5 to 20 ☌/min and the activation energy was 677 kJ/mol for the Fe2O3 phase. Additionally, the Fe2SiO4 phase formedwhen the cooling rate was more than 27 ☌/min and, as a result ofwater quenching (953 ☌/min), mixed crystalline (Fe2SiO4) and amorphous phases formed, the density was decreased to 4.714 g/cm3, and crack and void density increased. Therefore, to confirm the crushing efficiency of recyclable solidified iron ore, the microstructural, thermal, and mechanical properties were analyzed as a function of cooling rate.When the cooling ratewas increased from 5 to 20 ☌/min, the density of the iron ore decreased from 5.391 to 5.271 g/cm3, and the Fe2O3 phase formed. CONS: Poor mail filters inadequate address book.Solidified iron ore has been utilized as rawmaterial for aggregates of cement after crushing. RATING: PROS: Handles POP and IMAP e-mail offers excellent message searching supports multiple languages. But for experienced e-mail users, PowerMail isn’t ready to thrust aside the likes of Eudora Pro or the free Outlook Express. If you’re used to the free Eudora Light or the e-mail component of Netscape Communicator, you’ll find PowerMail 2.2’s abilities to be a revelation, as will those who receive mail in other languages. When you type the person’s name into the New Message form, PowerMail autocompletes the address entry, and there’s no way to tell which address you’ve gotten.Ī CTM Development spokesperson says that filtering and address-book changes are high on the list for future improvement. Worse, the obvious workaround for the latter problementering the name twiceis ineffective. The program sorts on the first name, not the last, and you can have only one e-mail address associated with each person. PowerMail’s address book also needs improvement. The usual bells and whistles are here: PowerMail colors quoted text in messages, lets you create folders and subfolders to manage your mail, and lets you choose from multiple signatures and multiple mail accounts. PowerMail also offers excellent multiple-language support you can mix and match different languages (for example, English and kanji text) within the same message. The program supports other important Apple technologies, such as AppleScript and drag and drop. PowerMail uses Apple’s V-Twin search technology (also found in Mac OS 8.5’s Sherlock) to index its mail database, resulting in fast searches, even through thousands of mail messages. But power users will find that the $49 package has a way to go before it can truly challenge Eudora Pro. CTM Development’s entry, PowerMail 2.2, supports both popular e-mail protocols (POP and IMAP) and makes it easy to switch from Eudoraor Claris Emailerby allowing you to import messages from either program. The competition is fierce among Mac-based e-mail clients, which include Microsoft’s free Outlook Express, Qualcomm’s Eudora Pro, and Bare Bones Software’s Mailsmith.
