Human Digestive system includes Gastrointestinal Tract and other accessory parts like the liver, intestines, glands, mouth, stomach, gallbladder. There are 6 main functions of the Human Digestive System Process: Ingestion, Motility, Secretion, Digestion, Absorption, Excretion. The food that you eat gives you not only the required energy and nutrients to the body but also is used for cell growth and repair.

D-Lab: Energy offers a hands-on, project-based approach that engages students in understanding and addressing the applications of small-scale, sustainable energy technology in developing countries where compact, robust, low-cost systems for generating power are required. Projects may include micro-hydro, solar, or wind turbine generators along with theoretical analysis, design, prototype construction, evaluation and implementation. Students will have the opportunity both to travel to Nicaragua during spring break to identify and implement projects. D-Lab: Energy is part of MIT’s D-Lab program, which fosters the development of appropriate technologies and sustainable solutions within the framework of international development. This course is an elective subject in MIT’s underGraduate / Professional Energy Studies Minor. This Institute-wide program complements the deep expertise obtained in any major with a broad understanding of the interlinked realms of science, technology, and social sciences as they relate to energy and associated environmental challenges.

D-Lab Development addresses issues of technological improvements at the micro level for developing countries—in particular, how the quality of life of low-income households can be improved by adaptation of low cost and sustainable technologies. Discussion of development issues as well as project implementation challenges are addressed through lectures, case studies, guest speakers and laboratory exercises. Students form project teams to partner with mostly local level organizations in developing countries, and formulate plans for an IAP site visit. (Previous field sites include Ghana, Brazil, Honduras and India.) Project team meetings focus on developing specific projects and include cultural, social, political, environmental and economic overviews of the countries and localities to be visited as well as an introduction to the local languages.

Student projects in D-Lab classes are defined by community partners and social ventures around the world. We don’t always know what is needed, but our community partners do, and our students have technical knowledge and skills to contribute to that work.
Each semester, through a selection of full-semester classes, our students form into teams to work on projects framed by community partners – NGOs, local nonprofits, and social entrepreneurs. At the end of each semester, students present their work to their peers, partners, and guests.

Short Description:
Drone Delivery of CBNRECy – DEW Weapons: Emerging Threats of Mini-Weapons of Mass Destruction and Disruption (WMDD) is our sixth textbook in a series covering the world of UASs and UUVs. Our textbook takes on a whole new purview for UAS / CUAS/ UUV (drones) – how they can be used to deploy Weapons of Mass Destruction and Deception against CBRNE and civilian targets of opportunity. We are concerned with the future use of these inexpensive devices and their availability to maleficent actors. Our work suggests that UASs in air and underwater UUVs will be the future of military and civilian terrorist operations. UAS / UUVs can deliver a huge punch for a low investment and minimize human casualties.

Long Description:
Drone Delivery of CBNRECy – DEW Weapons: Emerging Threats of Mini-Weapons of Mass Destruction and Disruption (WMDD) is our sixth textbook in a series covering the world of UASs & UUVs. Our textbook takes on a whole new purview for UAS / CUAS/ UUV (drones) – how they can be used to deploy Weapons of Mass Destruction and Deception against CBRNE and civilian targets of opportunity. We are concerned with the future use of these inexpensive devices and their availability to maleficent actors. Our work suggests that UASs in air and underwater UUVs will be the future of military and civilian terrorist operations. UAS / UUVs can deliver a huge punch for a low investment and minimize human casualties.

Repeating, we are concerned with the future use of these inexpensive devices and their availability to maleficent actors. As I write this description, we are on the 56th day of the savage invasion of Ukraine by Russia under President Putin. The Russian drone fleet numbers are above 500. They have had five years to grow their fleet. Russia currently uses them for domestic security, Syrian operations, and defense. (Facon, 2016) In the conflict, Russian troops seriously outnumber Ukrainian forces. However, on February 8, 2022, a Forbes report stated that Ukraine used 20 Turkish TB-2 drones to hit Russian targets and offset some of Russia’s enormous military advantages. (Malsin, 2022) According to Fox News, on February 27, 2022, President Putin ordered nuclear deterrent forces status raised to “special combat readiness” (Colton, 2022)

News like this in just one conflict suggests that UASs in air and underwater UUVs will be the future of military and civilian terrorist operations. UAS / UUVs can deliver a huge punch for a low investment and minimize human casualties. Our team believes that China is watching both the United States’ Neville Chamberlain appeasement strategy and the aggressive nature of Russia in its full-scale invasion of its neighbor. This portends that Taiwan is the next meal on the global plate. Unfortunately, two other state actors have season tickets: Iran and North Korea. Iran’s drone fleet is impressive and has caused other Gulf states’ inventories to escalate (UAE, Kingdom of Saudi Arabia, Egypt, Iraq, Jordan, Israel) (Barrie, 2021). North Korea (NK) lies about its air power. However, one report states that NK will have drones with stealth capability. (Choi, 2021) Maybe. According to Datablog, the US has the most drones and is best equipped for warfare. China, of course, might dispute these statistics. (DATABLOG, 2012) However, carrying a big stick doesn’t count anymore in the UAS’s future military play without the will to use it.

Our Wildcat team is composed of some impressive SMEs. We divided the work into four sections. Section 1 covers Chemical, Biological, Radiation, Nuclear, Explosive (CBRNE) weapons and payloads delivered by unmanned vehicles. Here we look at the technologies and damage delivered by drones as mini weapons of mass destruction and disruption. Chapter 7 concentrates on Deception and how drones can be used in PSYOPS and INFOWAR. Section 2 concentrates on Directed Energy Weapons (DEW), projectiles payloads, satellite killers, port disrupters, and cyberweapons against CBRN assets. Section 3 looks at policy considerations, risk assessments of threats and vulnerabilities of drone-based WMDD / DEW, practical crime scene investigations for hot zones, and unique challenges of responding to bioterrorism and chemical threats and attacks delivered by drones. Our final Section 4 concludes with social networking implications and DRONESEC security and tracking tools of the trade.

Over two years of solid research by a team of eleven SMEs is incorporated into our book. We trust you will enjoy reading it as much as we have in its writing. There are nightmares aplenty.

Through eight lessons, students are introduced to many facets of dams, including their basic components, the common types (all designed to resist strong forces), their primary benefits (electricity generation, water supply, flood control, irrigation, recreation), and their importance (historically, currently and globally). Through an introduction to kinetic and potential energy, students come to understand how dams generate electricity. They learn about the structure, function and purpose of locks, which involves an introduction to Pascal's law, water pressure and gravity. Other lessons introduce students to common environmental impacts of dams and the engineering approaches to address them. They learn about the life cycle of salmon and the many engineered dam structures that aid in their river passage, as they think of their own methods and devices that could help fish migrate past dams. Students learn how dams and reservoirs become part of the Earth's hydrologic cycle, focusing on the role of evaporation. To conclude, students learn that dams do not last forever; they require ongoing maintenance, occasionally fail or succumb to "old age," or are no longer needed, and are sometimes removed. Through associated hands-on activities, students track their personal water usage; use clay and plastic containers to model and test four types of dam structures; use paper cups and water to learn about water pressure and Pascal's Law; explore kinetic energy by creating their own experimental waterwheel from two-liter plastic bottles; collect and count a stream's insects to gauge its health; play an animated PowerPoint game to quiz their understanding of the salmon life cycle and fish ladders; run a weeklong experiment to measure water evaporation and graph their data; and research eight dams to find out and compare their original purposes, current status, reservoir capacity and lifespan. Woven throughout the unit is a continuing hypothetical scenario in which students act as consulting engineers with a Splash Engineering firm, assisting Thirsty County in designing a dam for Birdseye River.

Student must synthesize the data that go into the construction and operation of a large hydroelectric dam. Students must strive to develop a design that minimizes or mitigates the impacts of the dam on the existing watershed. Students divide the analysis and frequently present to each other their findings. These findings are then synthesized into independent reports produced by each student.

"Cancer cells are abnormal cells that rapidly proliferate and often find ways to evade the immune system’s attempts to stop them. Such cells often overexpress the genes MYC and ARF6 and have a mutated version of the KRAS gene. These changes are inextricably linked and result in significant resistance to cancer therapies. KRAS activates MYC gene expression and possibly promotes the translation of the messenger RNA for both MYC and ARF6. Then MYC induces expression of genes related to mitochondrial formation and energy production. Meanwhile, ARF6 protects the mitochondria from oxidation-induced injury. ARF6 may also promote cancer invasion, metastasis, and immune evasion. Thus, KRAS, MYC, and ARF6 cooperate to help cancer spread and to avoid the immune system and immune-based treatments. These harmful associations are common in pancreatic cancer and can be strengthened by mutations in other genes like TP53..."

Simulate the original experiment that proved that electrons can behave as waves. Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability.

This course explores natural and electric lighting that integrates occupant comfort, energy efficiency and daylight availability in an architectural context. Students are asked to evaluate daylighting in real space and simulations, and also high dynamic range photography and physical model building.

Students research electricity, its sources, how energy grids function, how to make grids most efficient, and how to bring different types of energy generation together to diversify grids. Students debate the costs and benefits of moving to a modernized Smart Grid.

In this lesson, students learn that sound is energy and has the ability to do work. Students discover that sound is produced by a vibration and they observe soundwaves and how they travel through mediums. They understand that sound can be absorbed, reflected or transmitted. Through associated activities, videos and a PowerPoint presentation led by the teacher, students further their exploration of sound through discussions in order to build background knowledge.

In this activity, students investigate the fascinating and complex process of decomposition and lay the foundation for deeper understanding of concepts related to matter and energy transfer in ecosystems. Through exploration and discussion, students go beyond simple definitions. Instead, students discover key characteristics of decomposition as they struggle with creating a sequence for decomposing wood and leaves. They learn the difference between physical decomposition and chemical decomposition and that many things contribute to decomposition, but certain organisms are classified as decomposers. They also search for and discuss evidence of decomposers, make model diagrams to further develop their ideas about the process of decomposition, and discuss decomposition and its role in the cycling of matter. Finally, students are challenged to recognize the evidence and impact of decomposition in the ecosystems they explore.

In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, atmospheric rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the blade, are discussed. For each case considered, the equations/model for the cutting forces, power and specific energy are given. The models are verified with laboratory research, mainly at the Delft University of Technology, but also with data from literature.

What lessons can we learn about genetically engineered organisms from the example of the jabberjay, a fictional bird in the movie “The Hunger Games”? In this lesson, students discuss the definition of genetically modified organisms, learn about the risks and benefits of research on G.M.O.’s, explore the growing do-it-yourself biology movement, and develop proposals seeking to either restrict or permit research into genetically modifying the avian flu virus.

"Oceanic microbiomes are critical to the global carbon cycle and to oceanic carbon and energy cycling, and the Deltaproteobacteria clade SAR324 is one of the few microbial groups inhabiting all oceanic depth zones. Although the metabolic potential of dark-zone SAR324 has been investigated, the ecology and metabolic traits of euphotic- and twilight-zone SAR324 remain unclear. To learn more, a recent study collected SAR324 from various depths of the North Pacific Subtropical Gyre. A pangenomic analysis including published genomic data revealed considerable intra-clade diversity, as indicated by the average nucleotide identity (ANI). The bacteria clustered into four ecotypes with different spatiotemporal distributions, and bacteria at different depths had different metabolic characteristics. The deep- and twilight-zone bacteria exhibited genomic and metabolic traits consistent with sulfur-based chemolithoautotrophy..."
