Want to take a fast trip to the edge of the Solar System? Consider a ride on a Heliopause
Electrostatic Rapid Transit System (HERTS). The concept is currently being tested and it might
take only 10 to 15 years to make the trip of over 100 Astronomical Units (15 billion kilometers).
That\'s fast compared to the 35 years it took Voyager 1, presently humanity\'s most distant
spacecraft, to approach the heliopause or outer boundary of the influence of the solar wind.
HERTS would use an advanced electric solar sail that works by extending multiple, 20 kilometer
or so long, 1 millimeter thin, positively charged wires from a rotating spacecraft. The
electrostatic force generated repels fast moving solar wind protons to create thrust. Compared to
a reflective solar light sail, another propellantless deep space propulsion system, the electric solar
wind sail could continue to accelerate at greater distances from the Sun, still developing thrust as
it cruised toward the outer planets..

Part I: The shape of the Milky Way
1. Look up the morphological classification of the Milky Way. There is a bit more to it than “spiral”. Look for information on morphological classification in text books and/or online. Find out the shape of the Milky Way galaxy.
[Type answer here]
2. Identify the parts the Milky Way. Some possible parts of a galaxy are: bulge, disk, halo, bar, or arm. Knowing the type of galaxy the Milky Way is, you should be able to identify the types of features the Milky Way has. Create a physical model of the Milky Way and identify the features it has. (A globe is an example of a physical model of Earth.) Describe your model and label all possible parts.
[Type answer here]
3. Use your planetarium software to observe the Milky Way from the northern and southern hemispheres. Based on your observations (without the aid of telescopes or other wavelengths of light outside the visible range) explain how these observations support the conclusion that we live in a galaxy with the shape of your model. Further, determine in what part of the galaxy the Sun must be located to see the Milky Way as we do.

Part II: Mapping the Milky Way with Globular Clusters
Galaxies like the Milky Way have objects, called “globular clusters” that exist in the outer regions of the galaxy (or halo). Globular clusters are dense clusters of stars that are generally free of gas and dust. In galaxies like the Milky Way, the gas and dust are located primarily in the disk. If we want to look for objects that we can see clearly (with no interference from gas and dust) we must observe objects in the halo. In the late 19th century an astronomer named Harlow Shapley devised an experiment to determine the position of Earth in the universe using globular clusters. He chose these objects because of their apparent lack of interaction with the gas and dust in the Milky Way.
Step 4.Explain how Shapley’s experiment could be used to determine the position of Earth within the Milky Way. Given what you already know about the part of the galaxy in which the Sun is located and the information about globular clusters, what information would Shapley need to figure out the position of Earth? For about how many globular clusters do you think he would need to get this information to determine the position of Earth? Describe the experiment and list the steps one would need to take.
[Type answers here]
Step 5. As a group, devise a method for determining the position of Earth within the Milky Way using globular clusters. Decide how many globular clusters you want to observe. Decide what information you need to do the analysis. There may be many different ways of analyzing the data, there does not need to be group consensus for the analysis, but each method that is used should be discussed with the group.

6. Gather the data you need from .
The curiosity to find earth-like planet can be dated to long time ago. But because of the incapability of the available technologies, it was a dream to detect planets beyond our solar system. After the time stated, the space research have taken a new leap and opened a new era of information. The concept of Exoplanet born. It can also be referred to as Extra Solar Planet. Any planet which is not within our solar system is Exoplanet. But an absolute definition is quite complex and problematic.

A concerned mother brings her 2-year-old daughter to the clinic with.pdfarihantcommunication
A concerned mother brings her 2-year-old daughter to the clinic with the complaint of fever,
irritability, and difficulty eating. Based upon what you have learned so far in class, what are
possible diagnoses and how would you differentiate between them?
Solution
In children the symptoms of epiglottitis include fever with chills difficulty swallowing refusing
to eat restlessness and irritability.
This disease can be diagnosed by observing X-rays and the wind pipe laryngoscopy.
The doctors day observed the swollen epiglottis by observing his throat.
Blood test also help observed infection ,other immunologic test also help for identifying the
antibodies to specific bacteria ore viruses.
Epiglottitis maybe misdiagnosed as strep throat. other misdiagnosis include infectious diseases
like diphtheria infectious mononucleosis, peritonsillar abscess.
An important misleading diagnosis is croup which occurs in younger children having viral
prodrome the children with croup has barking cough and rarely appears toxic they also it
experience sore throat, dyspnea and vomitings.
Epiglottis is very rare disease where as crop is very common epiglottis is caused by haemophilus
influenzae type b virus ,croup is caused by parainfluenza, rsv and enteror viruses ,epiglottis is
common in between the children 3 to 7 years where as crop is common between 3 months to 3
years. Fever is less in croup disease whereas fever > 39°c is observed in epiglottitis. Croup Is
benign where as epiglottitis is potentially critical.
Bacterial tracheitis may also mislead epiglottitis diagnosis..
Why is it important that chromosomes can cross over in Meiosis and n.pdfarihantcommunication
Why is it important that chromosomes can cross over in Meiosis and not in Mitosis?
Solution
Crossing over results in genetic recombination. It is responsible for genetic diversity of the
population. Genetic recombination and natural selection are the driving force behind evolution.
Meiosis is called sex division, it is responsible for gamate formation. Crossing over occurs when
chiasma is formed and this random exchange of information leads to unique gametes formation
and genetic recombination to occur..

There are many critical roles of engineering in addressing the large-scale pressing challenges
being faced by the societies worldwide. Such large-scale major challenges include access to
affordable health care; tackling the coupled issues of energy, transportation and climate change;
providing more equitable access to information for our populations; clean drinking water; natural
and man-made disaster mitigation, environmental protection and natural resource management,
among legion others. In and of itself, mobilizing the engineering community to become more
efficient in delivering real products and services of benefit to society, especially in the
developing world, is a vitally important international responsibility. Engineering as a human
strive is also facing numerous additional challenges of its own, including attracting and holding
back broader cross-sections of our youth, particularly women; strengthening the educational
enterprise; forging more effective interdisciplinary alliances with the natural and social sciences
and the arts; enhancing our focus on innovation, entrepreneurship and job creation, and;
promoting increased public awareness and support for the engineering enterprise..

What is the role of RFID chips in logistics?
What is the role of RFID chips in logistics?
Solution
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and
track tags attached to objects. The tags contain electronically stored information. Passive tags
collect energy from a nearby RFID reader\'s interrogating radio waves. Active tags have a local
power source such as a battery and may operate at hundreds of meters from the RFID reader.
Unlike a barcode, the tag need not be within the line of sight of the reader, so it may be
embedded in the tracked object. RFID is one method for Automatic Identification and Data
Capture (AIDC).[1]
The emergence of RFID (Radio Frequency Identification) technology has been greatly increased
efficiency in the production process management, material flow management, logistics and
transport, retail and distribution and other fields of the national economy industries, including
electronic information industry. RFID may eventually replace the ubiquitous bar code in the
future and become the main technology in logistics and supply chain management field
RFID in Logistics Management
Logistics management involves the efficient control of some or all of the supply chain functions,
including:
– Product research and development
– Sourcing and purchasing
– Manufacturing
– Production planning
– Sales, marketing, and forecasting
– Inventory management
– Cross-docking and flow-through
– Customer service
– Transportation
– Freight payment
– Information reporting
Using RFID logistics tracking has helped many organizations solve the main challenge at every
node in their supply chains: the lack of visibility of logistics data. RFID technology is a powerful
solution that improves asset visibility, data quality, inventory management, and interoperability
in an end-to-end integrated supply chain. In fact, the U.S. Department of Defense (DoD) issued a
mandate in 2005 that requires all of their suppliers to use RFID in marking any items that are
sold to the DoD. The need for this mandate arose from decades of logistical challenges faced by
the military with regard to the supply chain.
RFID has proven to alleviate various logistical problems associated with the DoD supply chain.
RFID technology, in combination with the Internet, allows the DoD to disseminate accurate,
real-time data to commanders worldwide so that assets can be easily located and used according
to the Department’s highest priorities..

Community policing is a philosophy that promotes organizational strategies, which support the
systematic use of partnerships and problem-solving techniques, to proactively address the
immediate conditions that give rise to public safety issues such as crime, social disorder, and fear
of crime.
Community policing is a philosophy of full service personalized policing, where the same officer
patrols and works in the same area on a permanent basis, from a decentralized place, working in
a proactive partnership with citizens to identify and solve problems.
Positive effects of Community policing :
Prevent crime
Address /Reduce fear of crime
Elicit the citizen development
Creative problem solving
Create active cooperation with Employee & Resident
Negative effect of community pricing :
The effects to examine is liability lawsuits
Risk taking leads to more litigation\'s and community-oriented policing involves risk taking due
to the modern management that is involved in community oriented policing
Nature & Extent of civil liability
Community pricing is dependent on community .Each community is different.
Primary focus of community policing:
The main focus of community policing is to solve the problems of society.For police
departments its not possible to control each & every thing , so they take some help from society .
The problems where arises these teams are helping to solve the problems.

Equations 17.7 and 17.8 depend on which assumption?
A) The screen is very close to the slits
B) the slits are much wider than the wavelength of the light
C) small angles (in radians)
D) large angles (in radians)
6.
You shine both red and blue light through a double slit. What can you say about their
interference patterns?
A) The red bright fringes will be closer together than will be the blue bright fringes.
B) The red and blue bright fringes will be the same distance apart from each other.
C) The blue bright fringes will be closer together than will be the red bright fringes.
7.
You compare a double-slit interference pattern with the interference pattern due to a diffraction
grating of the same spacing as that of the double-slit. The most noticeable difference would be
that:
A) The peaks of the diffraction grating are much broader than that for the double-slit
B) The peaks of the diffraction grating are much farther apart than for the double-slit
C) The peaks of the diffraction grating are much sharper than that for the double-slit
D) The peaks of the diffraction grating are much closer together than for the double-slit
E) The center point is a maximum, not a minimum
F) The center point is a minimum, not a maximum
Solution
(1).Both waves are at their maximum
(2).One wave is at a minimum; the other is at a maximum
(3).diffraction
(4).the light from one slit has to travel a dis.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Want to take a fast trip to the edge of the Solar System? Consider a ride on a Heliopause
Electrostatic Rapid Transit System (HERTS). The concept is currently being tested and it might
take only 10 to 15 years to make the trip of over 100 Astronomical Units (15 billion kilometers).
That's fast compared to the 35 years it took Voyager 1, presently humanity's most distant
spacecraft, to approach the heliopause or outer boundary of the influence of the solar wind.
HERTS would use an advanced electric solar sail that works by extending multiple, 20 kilometer
or so long, 1 millimeter thin, positively charged wires from a rotating spacecraft. The
electrostatic force generated repels fast moving solar wind protons to create thrust. Compared to
a reflective solar light sail, another propellantless deep space propulsion system, the electric solar
wind sail could continue to accelerate at greater distances from the Sun, still developing thrust as
it cruised toward the outer planets.
