Define relative refractory period
Solution
Relative refractory period is a phase of action potential.It is the time period during ehich a
stronger than normal stimulus is required to bring about an action potential. Right after the action
potential has moved down the axon,there is a time interval during which it is difficult for a
neuron to send another signal,this time period is called relative refractory period.After the
absolute refractory period,sodium chanels become to recover from inactivation and if during this
time period a stronger stimuli is given it can cause the generation of an action potential.During
relative refractory period continuous potassium ions flow out of the cell.
Therefore sodium channel inactivation and higher than resting pk values are responsible for
relative refractory period.

have a question.
Does parity have a generator? If so, what is it? If not, how is the condition of parity symmetry
expressed in terms of the operators?
Solution
The parity transformation, P, is a unitary operator, acting on a state as follows: P(r) = ei/2(r).
Also, P2(r) =ei(r), since an overall phase is unobservable. The operatorP2, which reverses the
parity of a state twice, leaves the spacetime invariant, and so is an internal symmetry which
rotates its eigenstates by phasesei. IfP2is an elementeiQof a continuous U(1) symmetry group of
phase rotations, theneiQ/2is part of this U(1) and so is also a symmetry. We can defineP=PeiQ/2,
which is also a symmetry, and so we can choose to callPour parity operator, instead ofP. Note
thatP2= 1 and soPhas eigenvalues ±1. However, when no such symmetry group exists, it may be
that all parity transformations have some eigenvalues which are phases other than ±1..

what is tax preference
Solution
Tax preferences are measures of the government under which different items are exempted from
paying taxes. Tax preference items are that type of income that are tax free and hence triggers
AMT (alternative minimum tax) for the taxpayers.
Examples of tax preference items are deductions for accelerated depreciation, excess intangible
drilling costs, capital gains from exercise of stocks etc.
Tax preference items are added to the AMT..

HIV stands for human immunodeficiency virus. If left untreated, HIV can lead to the disease
AIDS (acquired immunodeficiency syndrome). HIV attacks the body\'s immunity system,
specifically the CD4 cells (T cells), which help the immune system fight off infections. If left
untreated, HIV reduces the amount of CD4 cells (T cells) in the body, making the person more
prone to get infections or infection-related cancers. With time, HIV can destroy so many of these
cells that the body can\'t fight off infections and disease..

Write a C++ program that implements a binary search tree (BST) to manage a number of integer
items with different priorities. In order to do so. you will need to maintain a queue as an item in
the tree. Each queue item is an integer. All items in a given queue will have the same priority. As
a new item with a user-specified priority comes in, it should be enqueued in the queue with items
of that priority. A new queue may need to created in case a queue with that priority does not
exist. Use dynamic memory to manage nodes in the queue and BST. Implement the following:
Constructor. Destructor. Overloaded copy constructor. Overloaded assignment operator.
Overloaded \"==\" operator to check if two trees are equal. A tree t1 is equal to t2 if for every

Role of the gastric caeca in a grasshopper:
Gastric caeca are finger-like projections of the digestive tract found in many insects. These
pouches extend from the mid-gut and contain protozoa or bacteria that aid digestion,Gastric
caeca increase the surface area in the digestive tract increasing digestive enzyme secretion and
nutrient absorption.The gastric caeca project at the transition from foregut to mid-gut.
Insects feeding on difficult to digest materials, pouches called gastric caeca arise in the front of
the midgut. Each gastric caecum often contains protozoa and/or bacteria that aid in digestion..
what does it takes to be a living organ What does it take to be a l.pdfhardjasonoco14599
what does it takes to be a living organ? What does it take to be a living organism? Living things
share 8 characteristics that are listed in Chapter 1 of your textbook on page 19 Think of an
organism or cell in which all 8 characteristics are not obvious for example, coral looks like it
does not move, red blood cells do not reproduce and have no DNA. frogs freeze in the winter
therefore it seems as if they do not maintain homeostasis, and so on Focus your discussion on the
following Make comparisons between living things and nonliving things that have some of the
characteristics that define life Compare the following pairs and explain what the differences are
using the 8 criteria A rock to a snail A rock to a tree A dog to a TV Explain why electricity is
sometimes called line, or discuss some of the characteristics fire shares with living things (it can
grow, it metabolizes, and so on)
Solution
The 8 characteristics of living organisms are:
These 8 traits are generally used to classify organisms are either living or non-living. Things that
do not exhibit all 8 traits are scientifically classified as non-living. However, there are many
classified living things that do not visibly show all 8 characteristics. For example, trees are made
of cells, grow, evolve, reproduce, etc, but they do not physically move. Bacteria and other single
celled organisms do not show different levels of cellular organization. In ant colonies, only the
queen reproduces, yet even the non-reproducing worker ants are considered living. Viruses are
another hotly debated topic, as scientists continue to argue if they are living or non-living. While
outside the host body they may seem dead, when they enter the host they stir to life, using the
host\'s cellular machinery to reproduce, grow, assemble themselves before destroying the cell
and continuing the infection.
Sometimes, even non-living things seem to share a few traits of living things. For example,
icicles may be non-living, but in cold weather they can visibly \'grow\' as water freezes and the
icicle expands in size.
Comparing the following pairs:
Electricity and fire are often termed \'alive\' due to their behaviour, however, they are forms of
energy, not living organisms. Uncontrollable electricity is often termed \'live\', it travels through
conductive materials, it can even reproduce by distributing energy along various paths as it
travels. Similarly, fire, when provided with the right materials, can grow and spread. It
metabolizes fuel to maintain itself, and its movement and growth can be altered in response to
external stimuli. However, neither electricity nor fire consist of cells, nor do they evolve, and
being forms of energy, they cannot maintain homeostasis. Thus, they are classified as non-living..

Ball and socket joint is between humerus and scapula.
Hinge joint is between the humerus of the upper arm and the ulna and radius of the forearm.
Pivot joint : Pivot joints allow for rotation, which can be external (for example when rotating an
arm outward), or internal (as in rotating an arm inward).Example is proximal and distal
radioulnar joint
Condyloid joint : Oval shaped condyle of one bone fits into elliptical cavity of other bone. These
joints allow biaxial movements i.e. forward-backward and side to side but not rotation. Example
is the wrist joint.
Saddle joint : The carpometacarpal joint of the thumb makes the human thumb opposable by
allowing it to move across the palm to contact the other four fingers of the hand.
Plane joint :Plane joints permit sliding movements in the plane of articular surfaces.
This one is for you - assume that this pedigree shows the inheritance.pdfhardjasonoco14599
This one is for you - assume that this pedigree shows the inheritance of a rare autosomal
condition. Note that the father (II-4) is a known carrier and that this couple has had 3 normal
children. What is the probability that she is a carrier?
Solution
The disease is rare autosomal. In other words it is autosomal recessive disorder. Now the male
and female in II-1 and II-2 have disease. Lets call their genotype as \"aa\". But Their parents in I
generation are normal. This means they are carriers of the disease with genotype Aa and Aa.
Their third daughter II-3 has no disease, Her genotype can be Aa or AA, so probability to carry a
recessive allee a is 1/2. If she had had a diseased child, her genotype would have been Aa with
100%probability. But as has all healthy kids, probability of her being carrier is 1/2..

Solution
Answer1. Under the OSHA law, employers have a responsibility to provide a safe workplace.
Provide a workplace free from serious recognized hazards and comply with standards, rules and
regulations issued under the OSHA Act.
Examine workplace conditions to make sure they conform to applicable OSHA standards.
Make sure employees have and use safe tools and equipment and properly maintain this
equipment.
Provide medical examinations and training when required by OSHA standards and many other
OSHA standards.
Answer2. OSHA\'s standard for first aid training at Construction site
In the absence of an infirmary, clinic, or hospital in near proximity to the workplace which is
used for the treatment of all injured employees, a person or persons shall be adequately trained to
render first aid. Adequate first aid supplies shall be readily available.
The primary requirement addressed by these standards is that an employer must ensure prompt
first aid treatment for injured employees, either by providing for the availability of a trained first
aid provider at the worksite, or by ensuring that emergency treatment services are within
reasonable proximity of the worksite.
Answer3. The OSHA standards are divided into four major categories based on the type of work
being performed:agriculture(1928), construction (Part 1926), general industry (Part 1910) and
maritime (Part 1918).
The construction standard states that fall protection is required when an employee is working on
a walking/working surface (horizontal and vertical surface) with an unprotected side or edge
which is six feet or more a.

1. I can\'t get my RemoveItem() and ModifyItem() functions to work.
2. GetNumItemsInCart() is returning the wrong value. For example, my cart has 5 chocolate chip
cookies, 1 headphone, and 2 sneakers. GetNumItemsInCart() returns 3 instead of 8 when I output
my shopping cart.
3. When PrintDescriptions() is called, the first letter of my item description is missing. For
example, for the chocolate chip cookies, the description is Semi-sweet. When PrintDescriptions()
is called, it returns emi-sweet, with the S gone.
4. Shopping Cart improperly initialized with default constructor , and I don\'t know why.
12.9 Program: Online shopping cart (continued) (C++)
This program extends the earlier \"Online shopping cart\" program.
(1) Extend the ItemToPurchase class per the following specifications:
Parameterized constructor to assign item name, item description, item price, and item quantity
(default values of 0). (1 pt)
Public member functions
SetDescription() mutator & GetDescription() accessor (2 pts)
PrintItemCost() - Outputs the item name followed by the quantity, price, and subtotal
PrintItemDescription() - Outputs the item name and description
Private data members
string itemDescription - Initialized in default constructor to \"none\"
Ex. of PrintItemCost() output:
Ex. of PrintItemDescription() output:
(2) Create three new files:
ShoppingCart.h - Class declaration
ShoppingCart.cpp - Class definition
main.cpp - main() function (Note: main()\'s functionality differs from the warm up)
Build the ShoppingCart class with the following specifications. Note: Some can be function
stubs (empty functions) initially, to be completed in later steps.
Default constructor
Parameterized constructor which takes the customer name and date as parameters (1 pt)
Private data members
string customerName - Initialized in default constructor to \"none\"
string currentDate - Initialized in default constructor to \"January 1, 2016\"
vector < ItemToPurchase > cartItems
Public member functions
GetCustomerName() accessor (1 pt)
GetDate() accessor (1 pt)
AddItem()
Adds an item to cartItems vector. Has parameter ItemToPurchase. Does not return anything.
RemoveItem()
Removes item from cartItems vector. Has a string (an item\'s name) parameter. Does not return
anything.
If item name cannot be found, output this message: Item not found in cart. Nothing removed.
ModifyItem()
Modifies an item\'s description, price, and/or quantity. Has parameter ItemToPurchase. Does not
return anything.
If item can be found (by name) in cart, check if parameter has default values for description,
price, and quantity. If not, modify item in cart.
If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing
modified.
GetNumItemsInCart() (2 pts)
Returns quantity of all items .

How will the rate of diffusion of an interstitial i Impurity atom Inc.pdfhardjasonoco14599
How will the rate of diffusion of an interstitial i Impurity atom Increases? CIRCLE THE BEST
ANSWER Increase Decrease The rate of diffusion will be unaffected by changes In the size of
the impurity species. impurity species change as the size of the impurity species.
Solution
The rate of diffusion will decrease as the size of the impurity atoms increases because greater the
size of impurity atoms greater will be the difficulty in accomodating the impurity atoms at
interstitial sites and also larger size will decrease its mobility and provide hindrance during its
movement from one site to another. all these factors contribute in decrease in rate of diffusion..
Let R be an integral domain. Prove 1R and -1R are the only units of .pdfhardjasonoco14599
Let R be an integral domain. Prove 1R and -1R are the only units of R that are equal to their own
multiplicative inverses. Tip: Consider the equation x2 - 1R = 0R.
Solution
If x is its own inverse then
x^2-1 =0
(x-1)(x+1)=0
But, x is in R which is a domain
HEnce,
x-1=0 or x+1=0 as there are no zero divisors in R an integral domain
So, x=1 or -1.

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.

1. Define relative refractory period
Solution
Relative refractory period is a phase of action potential.It is the time period during ehich a
stronger than normal stimulus is required to bring about an action potential. Right after the action
potential has moved down the axon,there is a time interval during which it is difficult for a
neuron to send another signal,this time period is called relative refractory period.After the
absolute refractory period,sodium chanels become to recover from inactivation and if during this
time period a stronger stimuli is given it can cause the generation of an action potential.During
relative refractory period continuous potassium ions flow out of the cell.
Therefore sodium channel inactivation and higher than resting pk values are responsible for
relative refractory period
