Inhibitory Effect of some carbazides on corrosion of aluminium in hydrochlori...Al Baha University
Abstract
The dissolution of aluminium in hydrochloric acid and sodium hydroxide solutions in the presence of semicarbazide, thiosemicarbazide and sym.diphenylcarbazide as corrosion inhibitors has been studied using thermometric, weight-loss and polarization methods. The three methods gave consistent results. The higher inhibition efficiency of these compounds in acidic than in alkaline madia may be due to the less negative potential of aluminium in hydrochloric acid solution, favouring adsorption of the additive. The adsorption of these compounds were found to obey Frumkin adsorption isotherm. Cathodic polarization measurements showed that these compounds are cathodic inhibitors and their adsorptionin the double layer does not change the mechanism of the hydrogen evolution reaction. The results are analysed in terms of both molecular and cationic adsorption.

Sean V. Bradley is an automotive sales professional and CEO who has trained over 10,000 salespeople. He discusses typical dealership and salesperson averages for units sold and commissions per month. Most salespeople average $40,000-$46,000 annually without accounting for additional prospecting time. Bradley explains the importance of understanding expenses, tax rates, and average commission per copy (ACPC) to determine sales goals. Non-sales roles like BDC reps and appointment setters can also earn bonuses and commissions through pay plans tailored to their goals. Bradley advocates taking responsibility and accountability to maximize income through understanding the numbers.

This document is from the International Research Journal of Geology and Mining and discusses a study on the electro-thermal and semiconductivity behavior of a natural sintered complex carbonate ore. Specifically, it examines how sintering the Umm-Gheig carbonate ore at different temperatures affects its properties. Various analyses were conducted on samples sintered at 573K, 773K, 973K, and 1273K. Results showed the sintered ore exhibited semiconductivity behavior where electrical conductivity increased with temperature. Higher sintering temperatures led to more recombination between electrons and holes and increased conduction. Electron hopping between Fe2+ and Fe3+ were the main charge carriers
The document discusses various uses of the Internet. It outlines 5 key Internet applications: search engines to find data, e-mail to communicate electronically, e-commerce to conduct business online, chat to interact with others in real-time, and FTP to transfer files between servers and clients by uploading and downloading. The unit teaches students about these 5 active Internet applications to help them understand and benefit from using the Internet.

AJ LeBlanc – 12 Month Dealer Case Study for Video SEO And Video PreRollSean Bradley
This 12-month case study summarizes the results of Rick Case Honda's video pre-roll and video SEO conquest strategies in Miami, Florida over 12 months. The video pre-roll strategy involved targeting 3.6 million impressions to auto intenders in Miami, achieving a reach of 411,744 people with an average frequency of 11 views. This resulted in 50,761 total clicks over 12 months at a cost of $1.42 per click. The video SEO conquest strategy involved creating informational videos comparing Honda models to similar Toyota models. This resulted in Rick Case Honda organically outranking local Toyota dealers for relevant search terms, leading to a 688% increase in monthly Toyota trades completed by Rick Case
This document provides a 3 chapter summary of a novel titled "Dad" by Eustacie Matthew. The prologue discusses two stories of conflict - one involving a man taking hostages over financial issues being pushed to his limit, and another involving a married couple fighting violently over material things. Chapter 1 introduces the main character, Astin Wade, and discusses his career as a teacher in New York. It also examines issues of police brutality and racism through cases like the shooting of Amadou Diallo and beating of Abner Louima. Wade reflects on the importance of honesty and integrity in teaching.
Rome's empire expanded greatly over the first few centuries AD. Under emperors like Augustus, Rome conquered territories across Europe and Northern Africa, including Gaul, Britain, Asia Minor, Mesopotamia. This spread Roman control over the Mediterranean world and beyond. The empire promoted trade as Romans needed resources from the provinces to supply Rome. Traders brought goods across the empire in exchange for Roman coins and currency. The first 200 years of the empire saw the Pax Romana, a period of general peace and stability that allowed Rome to grow wealthy and its population to increase as trade flourished.
The document discusses how the author attracted and addressed their target audience for a magazine about an indie band called "The Ducks". To attract the audience, the author used bright colors on the cover, featured the band name in a contrasting blue, and included casual photographs of young models. The writing style within was informal with short sentences and youthful language. Photos depicted the band and models in indie styles and poses to match the genre and engage the intended teenage readership.
Several student artworks from different schools and grades were on display at various art shows and galleries. A self-portrait in pencil by an 8th grade gifted and talented student was shown at the Baltimore Museum of Art. A clay bell sculpture titled "Heavenly Dog" made by a 2nd grader was also displayed. A layered paper cut artwork called "Penguin Love" was shown at Walter's Art Gallery by a 7th grade gifted and talented student.

The document discusses sustainability efforts at the National Library of Australia (NLA). It outlines how the NLA has implemented various initiatives to use less energy, water, and paper. This includes turning off unused equipment, replacing inefficient equipment, insulating windows, installing LED and motion-sensor lighting, actively managing air conditioning schedules, replacing water meters, printing double-sided, and increasing recycling. As a result of these efforts, the NLA has seen reductions in energy and water usage as well as increases in the amount of materials recycled.
