ionic compounds when in the form of ions(in solut.pdf
ionic compounds when in the form of ions(in solution or molten state) would be
attracted to positive or negative plates depending on the charge on the ion.Positive ion would be
attracted to negative plate and negative ion would be attracted to positive plate. Whereas
covalent compounds are neutral so they would be attracted to positive/negative plates.
CH4,CH2Cl2,C2H2Cl2,CO2,O3 being covalent compounds do not produce ions so they would
not be attracted to positive or negative plates. (CO3)2- (carbonate ion) being a negatively
charged ion would be attracted to the (oppositely) positively charged plate. H2O although
covalent compound is slightly polar having very small concentration of H+ (in the form of
hydronium ions H3O+)and OH- ions thus these ions will be attracted to both the plates
depending on their nature of charge.

Please follow the data and description Doubly linked list In t.pdf
Please follow the data and description :
Doubly linked list :
In the filed of computer science, a doubly linked list is a linked data structure that consists of a
set of sequentially linked records called nodes. Each node contains two fields, called links, that
are references to the previous and to the next node in the sequence of nodes.
The example that has been provides is the :
3(head)-----> 7 ----->5-----> 9-----> 1(tail)
Now that we have a node defining the head and the tail of the list. And because they are double
referenced this means we can easily add or remove items from the head and the tail.
As there are given some lines of code that has to been predicted we follow it as :
a) current = head; :
This clearly indicates that the current position of the element is the head element which is the
element 3 in the present case.
So the current node element after the execution of the line is 3.
b) current = current.next; :
Now that the current element is the 3 which is the head so that the pointer is in the head element
and the command now says that current position of the element is the next element to the current
element. So by moving to the next element as this is possible in the linked list, we get the
element as 7.
So the current node element after the execution of the line is 7.
c) current = current.next; :
Now that the current element is the 7 which is the element next to head so that the pointer is in
the node element and the command now says that current position of the element is the next
element to the current element. So by moving to the next element as this is possible in the linked
list, we get the element as 9.
So the current node element after the execution of the line is 9.
d) current = current.previous; :
Now that the current element is the 9 and the command now says that current position of the
element is the previous element to the current element. So by moving to the previous element as
this is possible in the doubly linked list to move forth and backwards, we get the element as 7.
So the current node element after the execution of the line is 7.
e) current = current.next; :
Now that the current element is the 7 which is the element next to head so that the pointer is in
the node element and the command now says that current position of the element is the next
element to the current element. So by moving to the next element as this is possible in the linked
list, we get the element as 9.
So the current node element after the execution of the line is 9.
f) current = current.next; :
Now that the current element is the 9 and the command now says that current position of the
element is the next element to the current element. So by moving to the next element as this is
possible in the linked list, we get the element as 5.
So the current node element after the execution of the line is 5.
g) current = current.previous; :
Now that the current element is the 5 and the command now says that current position of the
element is the p.

Generally the formula for an acid is a hydrogen atom bonded with eit.pdf
Generally the formula for an acid is a hydrogen atom bonded with either another atom that is an
anion, such as Cl- (chlorine anion) or another molecule that is an anion, such as SO42- (sulfate
anion). What makes an acid an acid is that the hydrogen cation can fall off the molecule, known
as protonation, leaving behind a relatively stable anion. This anion is known as the acid\'s
conjugate base. A strong acid, such as HCl, has a weak conjugate base. A weak acid, such as HF,
would have a strong conjugate base. A strong acid is dictated by how much it protonates in
water, that is, how much the H+ cation dissociates from the anion in water. In HCl\'s case, the
acid protonates almost completely, making it a strong acid. The acidity of an acid is measured by
the well known pH scale. As you go upwards in difficulty of chemistry, molecules with multiple
hydrogens can have different acidities because when different hydrogens leave, they can form a
more or less stable anion behind.
I hope this helps!

Directives are JavaScript functions that manipulate and add behaviou.pdf
Directives are JavaScript functions that manipulate and add behaviours to HTML DOM
elements. Directives can be very simplistic or extremely complicated. Therefore, getting a solid
grasp on their many options and functions that manipulate them is critical.
There are many options that can be configured and how those options are related to each other is
important. Each directive undergoes something similar to a life cycle as AngularJS compiles and
links the DOM. The directive lifecycle begins and ends within the AngularJS bootstrapping
process, before the page is rendered. In a directive’s life cycle, there are four distinct functions
that can execute if they are defined. Each enables the developer to control and customize the
directive at different points of the life cycle.
The four functions are: compile, controller, pre-link and post-Link.
The compile function allows the directive to manipulate the DOM before it is compiled and
linked thereby allowing it to add/remove/change directives, as well as, add/remove/change other
DOM elements.
The controller function facilitates directive communication. Sibling and child directives can
request the controller of their siblings and parents to communicate information.
The pre-link function allows for private $scope manipulation before the post-link process begins.
The post-link method is the primary workhorse method of the directive.
In the directive, post-compilation DOM manipulation takes place, event handlers are configured,
and so are watches and other things. In the declaration of the directive, the four functions are
defined like this.
.directive(\"directiveName\",function() {
return{
controller:function() {
// controller code here...
},
link:function() {
// post-link code here...
}
}
})
Social policies are policies which are designed to address social issues, ranging from poverty to
racism. Many governments have agencies which formulate and administrate social policies, and
governments approach social issues in a variety of ways. Some countries often regarded as a very
progressive model when it comes to social policy, with a number of far-reaching programs which
are designed to promote equality in the European Union. Social policy reform can also take place
outside the government, as seen when community organizations work to support disadvantaged
citizens.
Social policies include: government pensions, welfare for the poor, food stamps, affordable
housing initiatives, health care, unemployment benefits, equal opportunityemployment laws,
antidiscrimination laws, and policy initiatives which are designed to benefit disadvantaged
people in society. For instance, many nations encourage their colleges and universities to accept
students regardless of need, with the goal of giving people at an economic disadvantage the
chance to go to college, improving their opportunities.

Cellular immunity mediated by T-cells, macrophages, and activity of Type-1 cytokines
(interleukin-12 [IL-12] and interferon [INF] gamma) is necessary for maintaining the quiescence
of chronic T. gondii infection. The production of IL-12 and INF gamma is stimulated by CD154
(also known as CD40 ligand) in human models of T. gondii infection. CD154 acts by triggering
dendritic cells and macrophages to secrete IL-12, which in turn enhances the production of INF
gamma by T-cells.In HIV infection due to immunosuppression opportunistic infection occurs
withT. gondiidue to depletion of CD4 T-cells, impaired production of IL-12 and INF gamma and
impaired cytotoxic T-lymphocyte activity. There is decreasedin vitroproduction of IL-12, INF
gamma, and decreased expression of CD154 in response toT. gondii

Answer: Option E IFN-Gamma is th most likely candidate for cytokinin x
Cellular immunity mediated by T-cells, macrophages, and activity of Type-1 cytokines
(interleukin-12 [IL-12] and interferon [INF] gamma) is necessary for maintaining the quiescence
of chronic T. gondii infection. The production of IL-12 and INF gamma is stimulated by CD154
(also known as CD40 ligand) in human models of T. gondii infection. CD154 acts by triggering
dendritic cells and macrophages to secrete IL-12, which in turn enhances the production of INF
gamma by T-cells.In HIV infection due to immunosuppression opportunistic infection occurs
withT. gondiidue to depletion of CD4 T-cells, impaired production of IL-12 and INF gamma and
impaired cytotoxic T-lymphocyte activity. There is decreasedin vitroproduction of IL-12, INF
gamma, and decreased expression of CD154 in response toT. gondii.

1.)The Occupational Safety and Health Administration, or OSHA, was.pdf
1.)
The Occupational Safety and Health Administration, or OSHA, was established in 1970 to
encourage employees and employers to decrease workplace hazards. OSHA recommends that
both parties cooperatively establish workplace-specific safety standards. The agency also
establishes training programs for occupational safety and health personnel. Finally, OSHA
oversees research to find new approaches to workplace safety and health issues, according to
Princeton University Environmental Health and Safety Department.
OSHA has had significant effects on workplace safety. Although U.S. employment has almost
doubled, workplace fatalities have gone down by more than 65 percent since OSHA’s inception.
There were about 38 worker deaths a day in 1970 as compared to 13 per day in 2011.
Occupational injury and illness rates have also lowered noticeably. In 1972 the workforce
experienced about 10.9 incidents per 100 workers as compared to fewer than 4 per 100 in 2010.
Compliance with OSHA regulations along with implementing your own well-designed safety
program can save your business money. Accidents and injuries occurring on the job can result in
major medical and legal expenses. Training your employees and having a program in place can
prevent these costly incidents from occurring. Maintaining a safe environment for your workers
rewards you with increased productivity and higher morale as well.
2.)
Industrial safety expert, H.W. Heinrich’s 10 axioms of industrial safety stem from his domino
theory. He said injuries occur due to a series of preventable incidents or factors. An accident
occurs as the last step or last falling domino.
\"Heinrich Revisited: Truisms or Myths\" by Fred A. Manuele, CSP, PE [2002, ISBN 0-87912-
245-5 published by National Safety Council offers the following in the last chapter. \"The intent
of this book is to present a review of the origin of certain of Heinrich\'s premises that became
accepted as truisms, how they evolved and changed over time, and to determine their validity. A
summary of the observations made in this book follows.
1. Files pertaining to Heinrich\'s research do not exist. Thus, there is no material to review as the
quality of research, or the analytical system used to arrive at his premises or their validity.
2. Heinrich\'s studies were made of accidents that occurred in the 1920s. Safety at work and the
workplace itself have changed substantively since then, as evidenced by noteworthy reductions
in accident experience in the past 70 years. Therefore, the current value and applicability of his
conclusions should be questioned and researched.
3. Although psychology has a place in safety management, the emphasis Heinrich gave to it as
being \"a fundamental of great importance in accident causation\" was disproportionate, and that
overemphasis influenced his work considerably.
4. Heinrich\'s 88-10-2 ratios indicate that among the direct and proximate causes, 88 percent are
unsafe acts, 10 percent are unsafe mechanica.

a) Find and replace – Text editors provide extensive facilities for searching and replacing text,
either on groups of files or interactively. Advanced editors can use regular expressions to search
and edit text or code.
b) Cut, copy, and paste – most text editors provide methods to duplicate and move text within the
file, or between files.
c) Ability to handle UTF-8 encoded text.
d) Text formatting – Text editors often provide basic formatting features like line wrap, auto-
indentation, bullet list formatting using ASCII characters, comment formatting, syntax
highlighting and so on.
e) Undo and redo – As with word processors, text editors provide a way to undo and redo the last
edit. Often—especially with older text editors—there is only one level of edit history
remembered and successively issuing the undo command will only \"toggle\" the last change.
Modern or more complex editors usually provide a multiple level history such that issuing the
undo command repeatedly will revert the document to successively older edits. A separate redo
command will cycle the edits \"forward\" toward the most recent changes. The number of
changes remembered depends upon the editor and is often configurable by the user.
f) Data transformation – Reading or merging the contents of another text file into the file
currently being edited. Some text editors provide a way to insert the output of a command issued
to the operating system\'s shell.
g) Filtering – Some advanced text editors allow the editor to send all or sections of the file being
edited to another utility and read the result back into the file in place of the lines being
\"filtered\". This, for example, is useful for sorting a series of lines alphabetically or numerically,
doing mathematical computations, indenting source code, and so on.
h) Syntax highlighting – contextually highlights source code, markup languages, config files and
other text that appears in an organized or predictable format. Editors generally allow users to
customize the colors or styles used for each language element. Some text editors also allow users
to install and use themesto change the look and feel of the editor\'s entire user interface.
i) Extensibility - a text editor intended for use by programmers must provide some plugin
mechanism, or be scriptable, so a programmer can customize the editor with features needed to
manage individual software projects, customize functionality or key bindings for specific
programming languages or version control systems, or conform to specific coding styles.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

Please follow the data and description Doubly linked list In t.pdf
Please follow the data and description :
Doubly linked list :
In the filed of computer science, a doubly linked list is a linked data structure that consists of a
set of sequentially linked records called nodes. Each node contains two fields, called links, that
are references to the previous and to the next node in the sequence of nodes.
The example that has been provides is the :
3(head)-----> 7 ----->5-----> 9-----> 1(tail)
Now that we have a node defining the head and the tail of the list. And because they are double
referenced this means we can easily add or remove items from the head and the tail.
As there are given some lines of code that has to been predicted we follow it as :
a) current = head; :
This clearly indicates that the current position of the element is the head element which is the
element 3 in the present case.
So the current node element after the execution of the line is 3.
b) current = current.next; :
Now that the current element is the 3 which is the head so that the pointer is in the head element
and the command now says that current position of the element is the next element to the current
element. So by moving to the next element as this is possible in the linked list, we get the
element as 7.
So the current node element after the execution of the line is 7.
c) current = current.next; :
Now that the current element is the 7 which is the element next to head so that the pointer is in
the node element and the command now says that current position of the element is the next
element to the current element. So by moving to the next element as this is possible in the linked
list, we get the element as 9.
So the current node element after the execution of the line is 9.
d) current = current.previous; :
Now that the current element is the 9 and the command now says that current position of the
element is the previous element to the current element. So by moving to the previous element as
this is possible in the doubly linked list to move forth and backwards, we get the element as 7.
So the current node element after the execution of the line is 7.
e) current = current.next; :
Now that the current element is the 7 which is the element next to head so that the pointer is in
the node element and the command now says that current position of the element is the next
element to the current element. So by moving to the next element as this is possible in the linked
list, we get the element as 9.
So the current node element after the execution of the line is 9.
f) current = current.next; :
Now that the current element is the 9 and the command now says that current position of the
element is the next element to the current element. So by moving to the next element as this is
possible in the linked list, we get the element as 5.
So the current node element after the execution of the line is 5.
g) current = current.previous; :
Now that the current element is the 5 and the command now says that current position of the

Generally the formula for an acid is a hydrogen atom bonded with eit.pdf
Generally the formula for an acid is a hydrogen atom bonded with either another atom that is an
anion, such as Cl- (chlorine anion) or another molecule that is an anion, such as SO42- (sulfate
anion). What makes an acid an acid is that the hydrogen cation can fall off the molecule, known
as protonation, leaving behind a relatively stable anion. This anion is known as the acid\'s
conjugate base. A strong acid, such as HCl, has a weak conjugate base. A weak acid, such as HF,
would have a strong conjugate base. A strong acid is dictated by how much it protonates in
water, that is, how much the H+ cation dissociates from the anion in water. In HCl\'s case, the
acid protonates almost completely, making it a strong acid. The acidity of an acid is measured by
the well known pH scale. As you go upwards in difficulty of chemistry, molecules with multiple
hydrogens can have different acidities because when different hydrogens leave, they can form a
more or less stable anion behind.
I hope this helps!

Directives are JavaScript functions that manipulate and add behaviou.pdf
Directives are JavaScript functions that manipulate and add behaviours to HTML DOM
elements. Directives can be very simplistic or extremely complicated. Therefore, getting a solid
grasp on their many options and functions that manipulate them is critical.
There are many options that can be configured and how those options are related to each other is
important. Each directive undergoes something similar to a life cycle as AngularJS compiles and
links the DOM. The directive lifecycle begins and ends within the AngularJS bootstrapping
process, before the page is rendered. In a directive’s life cycle, there are four distinct functions
that can execute if they are defined. Each enables the developer to control and customize the
directive at different points of the life cycle.
The four functions are: compile, controller, pre-link and post-Link.
The compile function allows the directive to manipulate the DOM before it is compiled and
linked thereby allowing it to add/remove/change directives, as well as, add/remove/change other
DOM elements.
The controller function facilitates directive communication. Sibling and child directives can
request the controller of their siblings and parents to communicate information.
The pre-link function allows for private $scope manipulation before the post-link process begins.
The post-link method is the primary workhorse method of the directive.
In the directive, post-compilation DOM manipulation takes place, event handlers are configured,
and so are watches and other things. In the declaration of the directive, the four functions are
defined like this.
.directive(\"directiveName\",function() {
return{
controller:function() {
// controller code here...
},
link:function() {
// post-link code here...
}
}

Social policies are policies which are designed to address social issues, ranging from poverty to
racism. Many governments have agencies which formulate and administrate social policies, and
governments approach social issues in a variety of ways. Some countries often regarded as a very
progressive model when it comes to social policy, with a number of far-reaching programs which
are designed to promote equality in the European Union. Social policy reform can also take place
outside the government, as seen when community organizations work to support disadvantaged
citizens.
Social policies include: government pensions, welfare for the poor, food stamps, affordable
housing initiatives, health care, unemployment benefits, equal opportunityemployment laws,
antidiscrimination laws, and policy initiatives which are designed to benefit disadvantaged
people in society. For instance, many nations encourage their colleges and universities to accept
students regardless of need, with the goal of giving people at an economic disadvantage the
chance to go to college, improving their opportunities.

gamma by T-cells.In HIV infection due to immunosuppression opportunistic infection occurs
withT. gondiidue to depletion of CD4 T-cells, impaired production of IL-12 and INF gamma and
impaired cytotoxic T-lymphocyte activity. There is decreasedin vitroproduction of IL-12, INF
gamma, and decreased expression of CD154 in response toT. gondii
Solution
Answer: Option E IFN-Gamma is th most likely candidate for cytokinin x
Cellular immunity mediated by T-cells, macrophages, and activity of Type-1 cytokines
(interleukin-12 [IL-12] and interferon [INF] gamma) is necessary for maintaining the quiescence
of chronic T. gondii infection. The production of IL-12 and INF gamma is stimulated by CD154

According to Hendersons Equation pOH = pKb + lo.pdf
According to Henderson\'s Equation pOH = pKb + log ([salt] / [base] ) = - log Kb +
log ( [NH4Cl] / [ NH3] ) = - log ( 1.8*10^-5) + log [( 1.5mol/5L) / ( 1.0 mol / 5.oL) ] = 5 - log
1.8 + log 1.5 = 4.92 pH = 14 - pOH = 14 - 4.92 = 9.08
Solution
According to Henderson\'s Equation pOH = pKb + log ([salt] / [base] ) = - log Kb +
log ( [NH4Cl] / [ NH3] ) = - log ( 1.8*10^-5) + log [( 1.5mol/5L) / ( 1.0 mol / 5.oL) ] = 5 - log
1.8 + log 1.5 = 4.92 pH = 14 - pOH = 14 - 4.92 = 9.08.
1.)The Occupational Safety and Health Administration, or OSHA, was.pdf
1.)
The Occupational Safety and Health Administration, or OSHA, was established in 1970 to
encourage employees and employers to decrease workplace hazards. OSHA recommends that
both parties cooperatively establish workplace-specific safety standards. The agency also
establishes training programs for occupational safety and health personnel. Finally, OSHA
oversees research to find new approaches to workplace safety and health issues, according to
Princeton University Environmental Health and Safety Department.
OSHA has had significant effects on workplace safety. Although U.S. employment has almost
doubled, workplace fatalities have gone down by more than 65 percent since OSHA’s inception.
There were about 38 worker deaths a day in 1970 as compared to 13 per day in 2011.
Occupational injury and illness rates have also lowered noticeably. In 1972 the workforce
experienced about 10.9 incidents per 100 workers as compared to fewer than 4 per 100 in 2010.
Compliance with OSHA regulations along with implementing your own well-designed safety
program can save your business money. Accidents and injuries occurring on the job can result in
major medical and legal expenses. Training your employees and having a program in place can
prevent these costly incidents from occurring. Maintaining a safe environment for your workers
rewards you with increased productivity and higher morale as well.
2.)
Industrial safety expert, H.W. Heinrich’s 10 axioms of industrial safety stem from his domino
theory. He said injuries occur due to a series of preventable incidents or factors. An accident
occurs as the last step or last falling domino.
\"Heinrich Revisited: Truisms or Myths\" by Fred A. Manuele, CSP, PE [2002, ISBN 0-87912-
245-5 published by National Safety Council offers the following in the last chapter. \"The intent
of this book is to present a review of the origin of certain of Heinrich\'s premises that became
accepted as truisms, how they evolved and changed over time, and to determine their validity. A
summary of the observations made in this book follows.
1. Files pertaining to Heinrich\'s research do not exist. Thus, there is no material to review as the
quality of research, or the analytical system used to arrive at his premises or their validity.
2. Heinrich\'s studies were made of accidents that occurred in the 1920s. Safety at work and the
workplace itself have changed substantively since then, as evidenced by noteworthy reductions
in accident experience in the past 70 years. Therefore, the current value and applicability of his
conclusions should be questioned and researched.
3. Although psychology has a place in safety management, the emphasis Heinrich gave to it as
being \"a fundamental of great importance in accident causation\" was disproportionate, and that
overemphasis influenced his work considerably.
4. Heinrich\'s 88-10-2 ratios indicate that among the direct and proximate causes, 88 percent are
unsafe acts, 10 percent are unsafe mechanica.

b) IEC 62304 (medical)
c) IEC 61513 (nuclear)
2. component from a text-editor GUI and the methods that it encapsulate.
a) Find and replace – Text editors provide extensive facilities for searching and replacing text,
either on groups of files or interactively. Advanced editors can use regular expressions to search
and edit text or code.
b) Cut, copy, and paste – most text editors provide methods to duplicate and move text within the
file, or between files.
c) Ability to handle UTF-8 encoded text.
d) Text formatting – Text editors often provide basic formatting features like line wrap, auto-
indentation, bullet list formatting using ASCII characters, comment formatting, syntax
highlighting and so on.
e) Undo and redo – As with word processors, text editors provide a way to undo and redo the last
edit. Often—especially with older text editors—there is only one level of edit history
remembered and successively issuing the undo command will only \"toggle\" the last change.
Modern or more complex editors usually provide a multiple level history such that issuing the
undo command repeatedly will revert the document to successively older edits. A separate redo
command will cycle the edits \"forward\" toward the most recent changes. The number of
changes remembered depends upon the editor and is often configurable by the user.
f) Data transformation – Reading or merging the contents of another text file into the file
currently being edited. Some text editors provide a way to insert the output of a command issued
to the operating system\'s shell.
g) Filtering – Some advanced text editors allow the editor to send all or sections of the file being
edited to another utility and read the result back into the file in place of the lines being
\"filtered\". This, for example, is useful for sorting a series of lines alphabetically or numerically,
doing mathematical computations, indenting source code, and so on.
h) Syntax highlighting – contextually highlights source code, markup languages, config files and
other text that appears in an organized or predictable format. Editors generally allow users to
customize the colors or styles used for each language element. Some text editors also allow users
to install and use themesto change the look and feel of the editor\'s entire user interface.
i) Extensibility - a text editor intended for use by programmers must provide some plugin
mechanism, or be scriptable, so a programmer can customize the editor with features needed to
manage individual software projects, customize functionality or key bindings for specific
programming languages or version control systems, or conform to specific coding styles.

ii. takes a positive integer n and returns the sum of the squares of all the positiv.

- High interest rates
- Appreciation of the local currency
2) Yes, the crisis in Turkey affects its entry in European union. Its economic situation will be a
matter of concern for the other EU nations. The main reason for this is that most of Turkey\'s
trade links are within Europe. However, Germany will be a strong support for Turkey.
3) When Turkish Lira did not devaluate as it was expected to, then the currency was pegged to

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
