A sweet and sparkling chapter book series about finding your place and believing in yourself! Marnie Blue’s adventures continue at Lady Sealia Foam’s Mermaid School. Now that she’s saved the day and made some new friends, she’s ready to conquer the next challenge and continue to learn more about her underwater world.

The equations for the motion, forces, and couples generated by clamshells released from spinning sounding rockets in accordance with a roll-out ejection concept are presented. The application of these equations to a study of a system for the Javelin (i.e., Honest John-Nike-Nike-X248) rocket vehicle is discussed. The roll-out ejection concept advocated requires that each deploying clamshell be pivoted about an axis at its trailing edge located in the system sectioning plane. Clamshell despinning is a consequence of this deployment since the pivotal, i.e., roll-out, rate is in opposition to the rocket vehicle spin. The energy required by the deployment is derived largely from the rotational energy of the clamshell. Thus, the rocket vehicle will not be significantly despun by this kind of clamshell deployment. This ejection concept also permits a system design which makes it possible to limit clamshell angular motion to rotation about that one of its centroidal principal axes which is brought into parallelism with the rocket vehicle longitudinal axis. Also, by equalizing the moments of inertia about the other centroidal principal axes, the rollout motion can be decoupled from any extraneous angular motion about these axes.

A sweet and sparkling chapter book series about finding your place and believing in yourself! It’s Marnie Blue’s first day at Lady Sealia Foam’s Mermaid School, and she’s terrified. What if she can’t make friends? What if she has to ride a seahorse? And what if the teachers assume she’s just like her Aunt Christabel, a famous singer who was a troublemaker growing up. Even though Marnie is sweet and tries her best to fit in, a mermaid named Orla seems intent on getting her in trouble. But when Orla finds herself in danger, Marnie has to swim to the rescue! Filled with fabulous, fishy fun, Mermaid School is the start of a sparkly new chapter-book series that’s sure to enchant young readers.

Equations for estimating the motion, forces, and couples applicable to the design of clamshell systems utilizing a new roll-out ejection concept are presented. Both the deployment and the free flight phases of the clamshell ejection are considered. No attempt is made to answer the thermal, vibratory, and structural detail problems of these clamsheils.

Marnie competes against her friend Orla and Gilly, a new student at Lady Sealia Foam's Mermaid School, for the lead role of Queen Maretta in the annual Clamshell Show.

This is an open access book. The covid-19 pandemic today forces humans to do almost all activities from home. Consequently, inventions in many fields of engineering technology are needed to facilitate those activities. First, human activities mainly are based on information technology today and internet connection is very important. People generate, send, and receive data by their smartphones every time and everything is connected to the internet. Equipment becomes smarter to assist the owner. Second, People need powerful, efficient, and smart vehicles and machines in Industry 4.0. Third, the need for energy increases, which causes the decrease of global environmental quality. It needs new technology for saving energy by discovering new technologies in mechanical engineering. Fourth, many technologies emerge as disaster prevention by developing innovations in civil engineering and architecture. The Engineering Faculty of University of Mataram invites engineers and researchers around the world to visit Lombok island and to attend the valuable multi fields conference on science and engineering named “The First Mandalika International Multi-conference on Science and Engineering 2022′′ or “1st MIMSE 2022”. This fruitful event will be the annual conference in Lombok island which is supported by the West Nusa Tenggara Province government. Initially, the 1st MIMSE 2022 consisted of 5 engineering fields are Civil, Architecture, Electrical, Mechanical, and Informatics Engineering.

The fourth chapter book in the charming, commercial series about a mermaid’s adventures at her new school Marnie Blue’s adventures at Lady Sealia Foam’s Mermaid School continue! Marnie is super excited because she’s going on a field trip to see the legendary palace of Queen Maretta with all her friends. But when her mom gets sick and can’t join the trip, Aunt Christabel agrees to come in her place—which is just a recipe for disaster! Christabel Blue is o-fish-ially the biggest troublemaker that the school has ever known. Will they board the whale-shark on time? Will the palace tour go off without a hitch? And just who is sneaking around the palace causing all the mischief?
