This document describes how drugs affect the nervous system. It discusses several types of drugs including stimulants, depressants, cocaine, opiates, marijuana, and alcohol. Stimulants like cocaine cause the sudden release of neurotransmitters like dopamine in the brain, while depressants like alcohol decrease heart rate. Long term use of drugs can lead to addiction and dependence on the drug both physically and psychologically. Drug abuse and sharing of needles also increases the risk of transmitting diseases.

Misinformation Theory
This summary provides an overview of how catecholamines and cortisol help the body fight stress:
1. Catecholamines (epinephrine and norepinephrine) and cortisol are major players in the stress response, helping the body deal with stress.
2. Both catecholamines and cortisol increase blood glucose levels through gluconeogenesis and preventing glucose uptake by cells.
3. They also increase cardiac output and blood pressure by enhancing heart contractility and rate, and vasoconstriction.
4. These hormonal responses help mobilize energy stores and prepare the body for fighting or fleeing from stressors.
Deeper Insights 3: The Use Of Drugs
This document discusses the use of drugs in mind control programming. It describes how drugs are used to stabilize programming after torture, hide codes, embed beliefs and identities. Extensive research has been done on how drugs influence memory, including the registration, retention and retrieval phases. Drugs like seconal are used to induce deep sleep after trauma and allow programming to set in. Scopolamine, electroshock and retrograde amnesia drugs are used to impair memory of events. Research facilities explored using LSD, RNA and stimulants to program people.

Section Summary
Several years ago I spent the academic year in a neurological research center affiliated with the teaching hospital at a medical center. One morning as I was having breakfast, I read a brief item in the newspaper about a man who had been hospitalized for botulism. Later that morning, I attended a weekly meeting during which the chief of neurology discussed interesting cases presented by the neurological residents. I was surprised to see that we would visit the man with botulism.
We entered the intensive care unit and saw that the man was clearly on his way to recovery. His face was pale and his voice was weak, but he was no longer on a respirator. There wasn’t much to see, so we went back to the lounge and discussed his case.
Just before dinner a few days earlier, Mr. F. had opened a jar of asparagus that his family had canned. He noted right away that it smelled funny. Because his family had grown the asparagus in their own garden, he was reluctant to throw it away. However, he decided that he wouldn’t take any chances. He dipped a spoon into the liquid in the jar and touched it to his tongue. It didn’t taste right, so he didn’t swallow it. Instead, he stuck his tongue out and rinsed it under a stream of water from the faucet at the kitchen sink. He dumped the asparagus into the garbage disposal.
About an hour later, as the family was finishing dinner, Mr. F. discovered that he was seeing double. Alarmed, he asked his wife to drive him to the hospital. When he arrived at the emergency room, he was seen by one of the neurological residents, who asked him, “Mr. F., you haven’t eaten some home-canned foods recently, have you?”
Learning that he had indeed let some liquid from a suspect jar of asparagus touch his tongue, the resident ordered a vial of botulinum antitoxin from the pharmacy. Meanwhile, he took a blood sample from Mr. F.’s vein and sent it to the lab for some in vivo testing in mice. He then administered the antitoxin to Mr. F., but already he could see that it was too late: The patient was showing obvious signs of muscular weakness and was having some difficulty breathing. He was immediately sent to the intensive care unit, where he was put on a respirator. Although he became completely paralyzed, the life support system did what its name indicates, and he regained control of his muscles.
What fascinated me the most was the in vivo testing procedure for the presence of botulinum toxin in Mr. F..
Substance abuses
Substance abuse affects the brain by altering normal brain messages as drugs have similar chemical structures to brain chemicals. Symptoms of substance abuse include talkativeness, anxiety, anger, and depression. Drug addiction is associated with negative outcomes like accidents, crimes, and health issues. While meditation and therapy can help, long-term medical treatment is often needed to cure chronic conditions and change criminal behaviors related to substance abuse. Help is available through various treatment organizations.
Substance abuses
Substance abuse is the use of drugs, alcohol, or chemicals. it is refers to the harmful or hazardous use of psychoactive substances, including alcohol and drugs.

My PPT_Drug treatment of Insomnia
Drug Treatment of Insomnia discusses the diagnosis and treatment of insomnia through both pharmacological and non-pharmacological means. It notes that insomnia is the perception of poor quality or inadequate sleep accompanied by distress or impaired function. Common patient populations with high rates of insomnia include women, the elderly, and those with psychiatric or medical disorders. Treatment includes lifestyle changes, cognitive behavioral therapy, and prescription medications like benzodiazepines, non-benzodiazepines, melatonin agonists, and the newer orexin antagonist suvorexant. A comprehensive sleep history should assess sleep patterns, quality, environmental factors, and behaviors to properly diagnose and treat insomnia.

THE AMERICAN DREAMThe American dream, the dream of opportunity f.docx
THE AMERICAN DREAM
The American dream, the dream of opportunity for all Americans to achieve prosperity through hard work is one that has evolved through years, ever since the years of Lord Dunmore, the governor of Virginia. It is a dream that many take it to be ambiguous, in which some believe to it is still live and others believing it is dead! It is therefore a topic worth exploring. To me this dream is still alive in every American who is hard-working and determined to make a change. America offers chances and opportunity for all, being a free and democratic nation and therefore this dream which is alive and those who pursue it shall have it come to reality. Indeed this dream is alive.
First, the American nation has good governance and democratic leadership. This opportunity in itself is enough and worth to make the diligent and hard-working to succeed and realize the dream. Many people from other countries have made America a place of refuge in seeking their prosperity; major reason being the great opportunities that the U.S is offering to its inhabitants as a result of the good governance. Indians, Africans Asians and other nationalities, in their success in America have therefore demonstrated this fact that the American dream is alive in those individuals who pursue it.
Secondly, America has supporting infrastructure such as good roads, excellent schooling facilities and a just system where everyone is given equal opportunity. These facilities steer the dream towards its realization. Nations worldwide send their scholars to the U.S on a yearly basis, that they may reap great results from the U.S facilities and opportunities and bring back home for the advancement of their native countries. If other nationals see this dream in the U.S, then indeed the dream is alive.
Finally, the United States of America has the one of the largest market for both locally produced goods and internationally availed goods. This vast market with thee well grown state of economy is a catalyst for the thriving of them that have decided to venture into business. Such have lived good and prosperous lives as a result of their business; lives of which is a realization of the American dream.
In conclusion, the American dream is alive in everyone who aspires to make achievements in life. It is an individual effort and not the country as a whole! American dream is alive.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement. Key words. stars: black holes– stars: formation– Galaxy: center– galaxies: star formation
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
