Crystal Structures as Geobarometers
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

This exercise is based on the recent formulation of a geobarometer based on the crystal structure of clinopyroxene (Nimis, 1995; 1998; 1999). This method relates structural parameters (e.g., the volumes of the unit cell and the M1 polyhedron) to the pressure at which the mineral crystallizes within basic and ultrabasic magmas.

students are guided into the American Mineralogist Crystal Structure Database to retrieve and download published crystal structure data for viewing in either the CrystalMaker or Xtaldraw visualization software packages.
students are instructed on how to examine the structures to determine pressure-sensitive crystallographic parameters
students are then asked a series of questions related to what they learn.

Short Description:
Disruptive Technologies With Applications in Airline, Marine, Defense Industries is our fifth textbook in a series covering the world of Unmanned Vehicle Systems Applications & Operations On Air, Sea, and Land. The authors have expanded their purview beyond UAS / CUAS / UUV systems that we have written extensively about in our previous four textbooks. Our new title shows our concern for the emergence of Disruptive Technologies and how they apply to the Airline, Marine and Defense industries. Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized, such that they are figuratively emerging into prominence from a background of nonexistence or obscurity. A Disruptive technology is one that displaces an established technology and shakes up the industry or a ground-breaking product that creates a completely new industry.That is what our book is about. The authors think we have found technology trends that will replace the status quo or disrupt the conventional technology paradigms.The authors have collaborated to write some explosive chapters in Book 5:Advances in Automation & Human Machine Interface; Social Media as a Battleground in Information Warfare (IW); Robust cyber-security alterative / replacement for the popular Blockchain Algorithm and a clean solution for Ransomware; Advanced sensor technologies that are used by UUVs for munitions characterization, assessment, and classification and counter hostile use of UUVs against U.S. capital assets in the South China Seas. Challenged the status quo and debunked the climate change fraud with verifiable facts; Explodes our minds with nightmare technologies that if they come to fruition may do more harm than good; Propulsion and Fuels: Disruptive Technologies for Submersible Craft Including UUVs; Challenge the ammunition industry by grassroots use of recycled metals; Changing landscape of UAS regulations and drone privacy; and finally, Detailing Bioterrorism Risks, Biodefense, Biological Threat Agents, and the need for advanced sensors to detect these attacks.

Long Description:
Disruptive Technologies With Applications in Airline, Marine, Defense Industries is the authors fifth textbook in a series covering the world of Unmanned Vehicle Systems & Operations On Air, Sea, Land; Counter Unmanned Aircraft Systems Technologies and Operations; Unmanned Aircraft Systems in the Cyber Domain: Protecting USA’s Advanced Air Assets, 2nd edition; and Unmanned Aircraft Systems (UAS) in the Cyber Domain Protecting USA’s Advanced Air Assets, 1st edition; have seen considerable global recognition in the field. (Nichols R. K., et al., 2020) (Nichols R. , et al., 2020) (Nichols R. , et al., 2019) (Nichols R. K., 2018)

The authors have expanded their purview beyond UAS / CUAS / UUV systems which they have written extensively about in our previous four textbooks. Our new title shows our concern for the emergence of Disruptive Technologies and how they apply to the Airline, Marine and Defense industries.

There is a difference between emerging technology trends and disruptive ones. Emerging technologies are technologies whose development, practical applications, or both are still largely unrealized, such that they are figuratively emerging into prominence from a background of nonexistence or obscurity. Some sources say that emerging technologies are taking over the world by a storm and if misused, it could turn out to be our worst enemy.

Disruptive technology is one that displaces an established technology and shakes up the industry or a ground-breaking product that creates a completely new industry. (Rouse, 2021)

That is what our book is about. The authors think they have found technology trends that will replace the status quo or disrupt the conventional technology paradigms.

The authors have written some explosive chapters in their Book 5. Dr. Hans Mumm has written about the Advances in Automation & Human Machine Interface. Wayne Lonstein, JD has given the reader a solid look at Social Media as a Battleground in Information Warfare (IW). CEO Bart Shields has delivered a viable, less risky, more robust cyber-security alterative / replacement for the popular Blockchain Algorithm and a clean solution for Ransomware. Professor Randall K. Nichols has written about the Advanced Sensor Technologies that are used by UUVs for munitions characterization, assessment, and classification. He reports on their counter hostile use of UUVs against U.S. capital assets in the South China Seas. In a second chapter, Professor Nichols has challenged the status quo and debunked the climate change fraud with verifiable facts. In his third chapter, he explodes our minds with Nightmare Technologies that if they come to fruition may do more harm than good.

Dr. Mark Jackson has written authoritatively about Propulsion and Fuels: Disruptive Technologies for Submersible Craft Including UUVs. CEO Randall Mai has penned a chapter to Challenge the Ammunition Industry by Grassroots use of Recycled Metals. Captain John Paul Hood writes about the changing landscape of UAS regulations and drone privacy laws. 2021 will prove to be most challenging for owners and manufacturers of UAS. CEO & Dr. Suzanne Sincavage and Professor Candice Carter have teamed up to scare the pants off of us – especially during the COVID-19 pandemic – by detailing Bioterrorism Risks, Biodefense, Threat Agents and the need for advanced sensors to detect these attacks. Their chapter is truly a wake-up call.

DRONE DELIVERY OF CBNRECy – DEW WEAPONS Emerging Threats of Mini-Weapons of Mass Destruction and Disruption ( WMDD)
Conditional Remix & Share Permitted

Rating
0.0 stars

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.

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.

Deciphering complex fluid-mineral interactions in the palm of your hand
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

Copper is an element that is essential to our technology and to our standard of living. Commonly, the copper is extracted from a variety of copper-bearing minerals that occur in veins. These fossilized fluid pathways record a complex set of geologic processes with non-linear couplings that are the products of hydrothermal activity associated with igneous intrusions (e.g. heat transport, mechanical fracture, mineral precipitation, permeability changes). By carefully examining a rock slab and its mineralogy, one can decipher the series of interrelated processes and their resultant impact on the final product.

Students set about to determine the relative age of veins by visual examination of the rock slab provided. Several generations of veins are recorded by different colors representing different minerals. Using cross-cutting relationships, they list the veins from oldest to youngest. Based on their color, they determine the sequence of minerals that fill veins. This provides an opportunity to review why color can be used to identify some minerals but not others. Once minerals are identified, their ideal chemical formula allows the percent copper in the mineral to be determined as well as the additional elements that must be present to form the mineral. The consequent change in mineral chemistry can be linked to the alterations in fluids flowing through the fractures by analysis of fluid-mineral equilibria on activity-activity (a-a) diagrams. For the more advanced classes, relevant thermodynamic data can be provided and students can write hydrolysis reactions and calculate the (a-a) diagram themselves.

Interpretation of the geologic history begins with the matrix and initial conditions and follows through rock fracture, fluid flow, mineral precipitation, evolving fluid composition, fracture sealing, pore-fluid pressure buildup, fracture, precipitation, etc. in a series of feedbacks. A feedback diagram can be provided and used as a base-map for interpretation not only of the sequence but changes to each reservoir, or students can be asked to draw the series of events and their reservoirs with the mechanisms of change. In the end, students understand the complex series of geologic processes that must come together in space and time to produce an ore-deposit that can be mined for our use. They also wrestle with the complications of reading the rock record and with the ambiguity of interpreting the interaction of various mechanisms that control the final product.

This contribution is modified from a published exercise "Directed Discovery of Crystal Structures Using Ball-and-Stick Models" [Mogk, 1997] . While the published exercise is based on student exploration of traditional ball-and-stick models of crystal structures, this modified version uses a similar "discovery-based" approach to teach the spatial relationships and crystal-chemical rules that govern the crystal structures of common minerals and crystalline solids, but instead uses the latest web-based crystallographic information and visualization programs. A few changes in the content have been made from the published exercise, mainly to accomodate the new digital media.
