Light waves superimpose each other and the redistribution of energy due to this can be observed in terms of well defined patterns of maxima and minima. Wherein, maxima refers to more energy and minima refers to less energy. Diffraction can also be called as interference in secondary wavelets.
This PowerPoint summarizes double-slit interference by transforming the interference patterns formed by Young's experiment into a right triangle. It is an attempt to clarify the significance of all of its components in order to determine different angles of which bright fringes appear on a screen L distance away from the two slits and eventually to conceptualize the distance between bright fringes by knowing the value of the wavelength of light.

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..

Solution
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 o.pdfarihantcommunication
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.

List and describe three examples of secondary sexual characteristics.pdfarihantcommunication
List and describe three examples of secondary sexual characteristics each for males and females.
Solution
Secondary sex characteristics are features that appear at sexual maturity in animals and during
puberty in humans, Secondary sex characteristics are Traits that distinguish the biological sexes
of a species, but are not directly part of the reproductive system.
Examples of secondary sex characteristics in humans include shorter stature and wider pelvis,
breast development, and more fat in the thighs and buttocks in women and broader shoulders,
greater muscle mass, more facial and other body hair, and “male pattern” baldness in men.
Male secondary sexual characteristics of hair:
The pubic regions is usually the first to develop hair
Facial hair begins at the corner of the mouth and spreads to the midline - followed by the rest of
the face
Body hair develops long before facial hair growth is complete (arm pit, legs, arms, buttocks,
back)
Male secondary sexual characteristics of vocal changes:
Rapid growth of the larynx - larger and stronger
The thyroid cartilage increases in dimension creating the Adam\'s apple
Vocal cords lengthen and thicken.
Male secondary sexual characteristics of the body:
Increase in body size, weight and strength (musculature)
Correlated to increase in testosterone levels
Female secondary sexual characteristics of hair:
The pubic regions is usually the first to develop hair
Body hair develops slightly later (arm pit, legs, arms)
female secondary sexual characteristics of the pelvis:
Broadens and changes from a narrow funnel-like outlet, to a broad oval outlet, flaring at the hip
Fat cells increase in number around the buttocks and thighs
Female secondary sexual characteristics of the breasts:
Tanner Stages
Tanner I
no glandular tissue, typically age 10 and younger
Tanner II
Breast bud forms, with small area of surrounding glandular tissue, 10-11.5
Tanner III
breast begins to become more elevated, and extends beyond the borders of the areola, 11.5-13
Tanner IV
increased breast size and elevation, 13-15
Tanner V
breast reaches final adult size, 15+.

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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

1.In which case(s) is there constructive interference for two ligh.pdf
1. 1.
In which case(s) is there constructive interference for two light waves meeting at the same point
at a given instant? (Select all that apply.)
A) Both waves are at their minimum
B) One wave is at its maximum, one wave is at zero.
C) Both waves are at their maximum
D) One wave is at its minimum, one wave is at zero.
E) One wave is at its maximum, the other is at its minimum
2.
In which situation(s) is there destructive interference when two waves intersect at one point? (At
an instant of time.)
A) Both waves are at a maximum
B) One wave is at a maximum, the other is at zero
C) One wave is at a minimum; the other is at a maximum
D) Both waves are at a minimum
E) One wave is at a minimum, the other is at zero
3.
When light goes through a very narrow slit, it spreads out from that slit in all directions beyond
the slit due to:
A) diffraction
B) dispersion
C) interference
D) refraction
E) reflection
4.
Light encounters two very narrow slits closely spaced together. Constructive interference of light
coming from these two slits will occur when
A) the wavelength of the light equals the width of the slits
B) the wavelength of the light equals the separation of the slits
C) the light from one slit has to travel a distance that is longer than that traveled by the light
from the other slit equal to half the wavelength of the light
D) light from one slit at its crest encounters light from the other slit at its trough
E) the light from one slit has to travel a distance that is longer than that traveled by the light
from the other slit equal to twice the wavelength of the light
5.
2. 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 distance that is longer than that traveled by the light
from the other slit equal to twice the wavelength of the light
(6).The blue bright fringes will be closer together than will be the red bright fringes.
(7).The peaks of the diffraction grating are much sharper than that for the double-slit
