1. Working capital is the capital that a company uses for its day to day operations. Working
capital is computed using the formula: Working capital = current assets – current liabilities.
2. Determinants of working capital requirements are – nature of business, seasonality of
operations, production policy, market conditions and conditions of supply. A service company
will have a lower working capital requirement than a manufacturing company. Firms with
seasonality in operations will have higher fluctuations with regards to their working capital
requirements. Market conditions in the form of degree of competition will affect working capital
requirements. Higher competitive pressure will increase working capital requirements.
3. Three major decisions that managers have to take while performing the finance function are:
(i) Investment decision – Managers have to select those assets that the business will invest in. It
is also known as capital budgeting decisions.
(ii) Financing decision – These decisions pertain to determining how the total funds that are
required for the business will be obtained – will it be through debt or equity or a mix of debt or
equity.
(iii) Dividend decision – This pertains to determining what quantum of earnings should be
distributed to shareholders as dividends and what quantum should be retained for meeting future
growth requirements of the company.
4. Financial management involves planning, directing, monitoring and controlling the monetary
resources of a company in such a manner that the goals and objectives of the company are
achieved in an efficient manner. It involves management of capital budgeting, capital structure,
working capital management, etc. Financial management is important as it helps an organization
to set clarity towards its financial goals and helps in efficient utilization of resources.
5. Cash flow is not a suitable judge of profitability as it merely shows the changes in cash
position of a firm in a financial year from its operating activities, from its financing activities and
from its investing activities. Cash flow statement does not help us to determine gross profit
margins, operating profit margins and net profit margins. We can just gauge the reason for
changes in cash position in a year.
6. Financial risk refers to all kinds of risk associated with a financial transaction and an
investment transaction. It can be in the form of credit risk, asset backed risk, investment risk etc.
These risks arise due to the fact that there is a probability of loss that is inherent in any financing
and investment method and this probability of loss cannot be avoided.

It is a molecular process involving the exchange of bonds between the two reacting
chemical species, which results in the creation of products with similar or identical bonding
affiliations. This is represented by the general reaction scheme: AX + BY ? BX + AY These
chemical species can either be ionic or covalent. When referring to precipitation reactions
between solutions of ions in inorganic chemistry, these were formerly referred to as double
displacement or double replacement reactions, and these terms are still encouraged. It seems that
the term double decomposition is more specifically used when at least one of the substances does
not dissolve in the liquor, as the ligand or ion exchange takes place in the solid state of the
reactant, i.e. AX(aq) + BY(s) ? AY(aq) + BX(s). Types: Neutralization A neutralization reaction
is a specific type of double displacement reaction. Neutralization occurs when an acid reacts with
an equal amount of a base. A neutralization reaction creates a solution of a salt and water. For
example, hydrochloric acid reacts with sodium hydroxide to produce salt and water: HCl (aq) +
NaOH (aq) ? NaCl (aq) + H2O (l) Aqueous metathesis (precipitation) Metathesis reactions can
occur between two inorganic salts when one product is insoluble in water, driving the reaction
forward. For example, the precipitation of silver chloride from a mixture of silver nitrate and
sodium chloride causes sodium nitrate to be left in solution: AgNO3 (aq) + NaCl (aq) ? AgCl (s)
+ NaNO3 (aq) The formation of an insoluble gas that bubbles out of the solution, or a molecular
compound such as water, also drives the reaction to completion. Therefore, a solubility chart (or
general knowledge of solubility rules) can be used to predict whether two aqueous solutions will
react. HSAB theory can also be used to predict the products of a metathesis reaction. Aqueous
metathesis (double decomposition) The reactants need not to be dissolved for metathesis
reactions to take place. An example of this is the formation of barium thiocyanate when boiling a
mixture of copper(I)thiocyanate and barium hydroxide in water: Ba(OH)2 (s) + 2 CuCNS (s) ?
Ba(CNS)2 (aq) + 2CuOH (s) Acid and carbonates A subcategory of aqueous metathesis
reactions is the reaction of an acid with a carbonate or bicarbonate. Such a reaction always yields
carbonic acid as a product, which spontaneously decomposes into carbon dioxide and water. The
release of carbon dioxide gas from the reaction mixture drives the reaction to completion. For
example, a common, science-fair \"volcano\" reaction involves the reaction of acetic acid with
sodium bicarbonate: HCH3COO (aq) + NaHCO3 (s) ? NaCH3COO (aq) + CO2 (g) + H2O (l)

From the LCAO method: The overlap of the 1s AO on one H atom with the is AO
on a second gives one bonding MO (s) at lower energy to the constituent AOs and one
antibonding MO (s*) at higher energy. Each MO can hold 2 e-. H2^- has 3e- and so the MO
\"scheme\" is s(2e-) s*(1e-) Bond Order = ½[S (bonding e-) - S (antibonding e-)] = ½[2-1] = 0.5
so H2^2- is predicted to be bonding. When irradiated with UV light an e- in the s MO is
promoted to the s*: s(2e-) s*(1e-) ? h? ? s(1e-) s*(2e-) ? dissociation The bond order of the
excited state is formally ½[1-2] = -0.5 which is repulsive: the species flies apart into H^- and H.
(H atom not a period). You have to look at an MO diagram for O2; if you do that, focusing on
the p-based orbitals, you\'ll see that there are 6 bonding electrons (2 in the p-sigma orbital, and 4
in the p-pi orbitals), and two electrons in the p-pi* (one in each). Thus there are six bonding
electrons and two antibonding electrons, so the net is four bonding electrons. Since it takes two
bonding electrons to make a bond, the bond order is 2 for O2. If you take away one of the
antibonding electrons, now you have a net of five bonding electrons, which - when divided by 2 -
gives you a bond order of 2.5. Because you\'ve taken away one electron from neutral O2, the
charge will be +1.

Cis-trans isomers occur because it is impossible to rotate the double bond without
breaking it. Thus, isomers that are related by \"rotation\" about the double bond are actually
separate compounds - cis/trans isomers. In the example you have drawn, keep the -CH2CH3
group and the right-hand H in place and reverse the position of the -CH2CH2CH3 group and the
other H (so that the H\'s are on \"opposite\" sides of the double bond). This is the trans isomer of
the compound you drew (you have the cis isomer). Now, imagine that instead of the
CH2CH2CH3 group you had another H. In that case, switching the position of the two H\'s
would result in the same compound, and cis-trans isomers would not be possible. In general,
cis/trans isomers are possible only if each carbon that is part of the double bond is bonded to two
DIFFERENT groups. This is only true for I and III. In II, the right-hand carbon of the double
bond is bonded to two H\'s. And in IV, the left hand carbon of the double bond is bonded to two -
CH3 groups. Thus neither of these has cis-trans isomers. So the correct answer is (b), I and III.

When a heterozygote (Aa) is not an exact intermediate between the tw.pdfanjaliselectionahd
When a heterozygote (Aa) is not an exact intermediate between the two homozygotes (AA and
aa), then not all of the genetic variance in the population can be accounted for by differences in
the average effect of the A and a alleles.
In this case, the total genetic variance of the population can be subdivided into two components:
Additive Genetic Variance (sa2): Genetic variation attributed to average differences between
different allelic characters.
Dominance Genetic Variance (sd2): Variance due to heterozygotes not being exact midpoints of
homozygote parents.
So that,
Sg2 = Sa2 + Sd2
And now, total phenotypic variance can be rewritten as:
Sp2 = Se2 + Sg2 = Se2 + Sa2 + Sd2
From this, we can define a new kind of heritability:
Heritability in the narrow sense (h2):Proportion of phenotypic variance due to additive genetic
variance alone
h2 = Sa2 / Sp2 = Sa2 / Se2 + Sg2 = Sa2 / Se2 + Sd2 + Sa2
The greater h2 is for a population, the greater the fraction of the difference between selected
parents and the population as a whole that will be preserved in the offspring of those parents.
______________________________________________________________
To see why it is h2 that matters for response to selection, consider an extreme case:
2 homozygotes are equal in phenotype, say with a value of 20. (AA=aa=20)
But the heterozygote is overdominant, maybe with a value of 24. (Aa=24)
So for this population, there is only dominance variance, and no additive genetic variance
because there is no average difference between the carriers of a alleles and the carriers of A
alleles.
Now suppose that the population mates randomly and the genotype proportions are:
If only individuals with the highest values were selected to breed, all parents would be
heterozygotes.
Offspring of heterozygotes would exactly reproduce the 1:2:1 distribution of genotypes seen in
the parental generation.
Thus, there would be no change in genetic composition of the F1 generation, despite the fact
that there is genetic variation in the population.
So, selection proves to be ineffective when all variance is due to dominance and there is no
additive variance.
It is important to consider that dominance variance arises from more than just the deviation of
heterozygotes from the exact midpoint of homozygotes.
Dominance variance (sd2) is considered to be any genetic variation that cannot be explained by
average allelic differences, or additive genetic variance (sa2)
For example, if a trait is affected by multiple loci then any epistatic interactions between the loci
will appear as variance not associated with additive variance.
In theory, this interaction variance (si2) could be separated from dominance variance (sd2).
In practice, however, it is not possible to achieve accurate measures of separating these two
parameters so all nonadditive variance is attributed to dominance variance (sd2).

It is a molecular process involving the exchange of bonds between the two reacting
chemical species, which results in the creation of products with similar or identical bonding
affiliations. This is represented by the general reaction scheme: AX + BY ? BX + AY These
chemical species can either be ionic or covalent. When referring to precipitation reactions
between solutions of ions in inorganic chemistry, these were formerly referred to as double
displacement or double replacement reactions, and these terms are still encouraged. It seems that
the term double decomposition is more specifically used when at least one of the substances does
not dissolve in the liquor, as the ligand or ion exchange takes place in the solid state of the
reactant, i.e. AX(aq) + BY(s) ? AY(aq) + BX(s). Types: Neutralization A neutralization reaction
is a specific type of double displacement reaction. Neutralization occurs when an acid reacts with
an equal amount of a base. A neutralization reaction creates a solution of a salt and water. For
example, hydrochloric acid reacts with sodium hydroxide to produce salt and water: HCl (aq) +
NaOH (aq) ? NaCl (aq) + H2O (l) Aqueous metathesis (precipitation) Metathesis reactions can
occur between two inorganic salts when one product is insoluble in water, driving the reaction
forward. For example, the precipitation of silver chloride from a mixture of silver nitrate and
sodium chloride causes sodium nitrate to be left in solution: AgNO3 (aq) + NaCl (aq) ? AgCl (s)
+ NaNO3 (aq) The formation of an insoluble gas that bubbles out of the solution, or a molecular
compound such as water, also drives the reaction to completion. Therefore, a solubility chart (or
general knowledge of solubility rules) can be used to predict whether two aqueous solutions will
react. HSAB theory can also be used to predict the products of a metathesis reaction. Aqueous
metathesis (double decomposition) The reactants need not to be dissolved for metathesis
reactions to take place. An example of this is the formation of barium thiocyanate when boiling a
mixture of copper(I)thiocyanate and barium hydroxide in water: Ba(OH)2 (s) + 2 CuCNS (s) ?
Ba(CNS)2 (aq) + 2CuOH (s) Acid and carbonates A subcategory of aqueous metathesis
reactions is the reaction of an acid with a carbonate or bicarbonate. Such a reaction always yields
carbonic acid as a product, which spontaneously decomposes into carbon dioxide and water. The
release of carbon dioxide gas from the reaction mixture drives the reaction to completion. For
example, a common, science-fair \"volcano\" reaction involves the reaction of acetic acid with
sodium bicarbonate: HCH3COO (aq) + NaHCO3 (s) ? NaCH3COO (aq) + CO2 (g) + H2O (l)

From the LCAO method: The overlap of the 1s AO on one H atom with the is AO
on a second gives one bonding MO (s) at lower energy to the constituent AOs and one
antibonding MO (s*) at higher energy. Each MO can hold 2 e-. H2^- has 3e- and so the MO
\"scheme\" is s(2e-) s*(1e-) Bond Order = ½[S (bonding e-) - S (antibonding e-)] = ½[2-1] = 0.5
so H2^2- is predicted to be bonding. When irradiated with UV light an e- in the s MO is
promoted to the s*: s(2e-) s*(1e-) ? h? ? s(1e-) s*(2e-) ? dissociation The bond order of the
excited state is formally ½[1-2] = -0.5 which is repulsive: the species flies apart into H^- and H.
(H atom not a period). You have to look at an MO diagram for O2; if you do that, focusing on
the p-based orbitals, you\'ll see that there are 6 bonding electrons (2 in the p-sigma orbital, and 4
in the p-pi orbitals), and two electrons in the p-pi* (one in each). Thus there are six bonding
electrons and two antibonding electrons, so the net is four bonding electrons. Since it takes two
bonding electrons to make a bond, the bond order is 2 for O2. If you take away one of the
antibonding electrons, now you have a net of five bonding electrons, which - when divided by 2 -
gives you a bond order of 2.5. Because you\'ve taken away one electron from neutral O2, the
charge will be +1.

Cis-trans isomers occur because it is impossible to rotate the double bond without
breaking it. Thus, isomers that are related by \"rotation\" about the double bond are actually
separate compounds - cis/trans isomers. In the example you have drawn, keep the -CH2CH3
group and the right-hand H in place and reverse the position of the -CH2CH2CH3 group and the
other H (so that the H\'s are on \"opposite\" sides of the double bond). This is the trans isomer of
the compound you drew (you have the cis isomer). Now, imagine that instead of the
CH2CH2CH3 group you had another H. In that case, switching the position of the two H\'s
would result in the same compound, and cis-trans isomers would not be possible. In general,
cis/trans isomers are possible only if each carbon that is part of the double bond is bonded to two
DIFFERENT groups. This is only true for I and III. In II, the right-hand carbon of the double
bond is bonded to two H\'s. And in IV, the left hand carbon of the double bond is bonded to two -
CH3 groups. Thus neither of these has cis-trans isomers. So the correct answer is (b), I and III.

When a heterozygote (Aa) is not an exact intermediate between the tw.pdfanjaliselectionahd
When a heterozygote (Aa) is not an exact intermediate between the two homozygotes (AA and
aa), then not all of the genetic variance in the population can be accounted for by differences in
the average effect of the A and a alleles.
In this case, the total genetic variance of the population can be subdivided into two components:
Additive Genetic Variance (sa2): Genetic variation attributed to average differences between
different allelic characters.
Dominance Genetic Variance (sd2): Variance due to heterozygotes not being exact midpoints of
homozygote parents.
So that,
Sg2 = Sa2 + Sd2
And now, total phenotypic variance can be rewritten as:
Sp2 = Se2 + Sg2 = Se2 + Sa2 + Sd2
From this, we can define a new kind of heritability:
Heritability in the narrow sense (h2):Proportion of phenotypic variance due to additive genetic
variance alone
h2 = Sa2 / Sp2 = Sa2 / Se2 + Sg2 = Sa2 / Se2 + Sd2 + Sa2
The greater h2 is for a population, the greater the fraction of the difference between selected
parents and the population as a whole that will be preserved in the offspring of those parents.
______________________________________________________________
To see why it is h2 that matters for response to selection, consider an extreme case:
2 homozygotes are equal in phenotype, say with a value of 20. (AA=aa=20)
But the heterozygote is overdominant, maybe with a value of 24. (Aa=24)
So for this population, there is only dominance variance, and no additive genetic variance
because there is no average difference between the carriers of a alleles and the carriers of A
alleles.
Now suppose that the population mates randomly and the genotype proportions are:
If only individuals with the highest values were selected to breed, all parents would be
heterozygotes.
Offspring of heterozygotes would exactly reproduce the 1:2:1 distribution of genotypes seen in
the parental generation.
Thus, there would be no change in genetic composition of the F1 generation, despite the fact
that there is genetic variation in the population.
So, selection proves to be ineffective when all variance is due to dominance and there is no
additive variance.
It is important to consider that dominance variance arises from more than just the deviation of
heterozygotes from the exact midpoint of homozygotes.
Dominance variance (sd2) is considered to be any genetic variation that cannot be explained by
average allelic differences, or additive genetic variance (sa2)
For example, if a trait is affected by multiple loci then any epistatic interactions between the loci
will appear as variance not associated with additive variance.
In theory, this interaction variance (si2) could be separated from dominance variance (sd2).
In practice, however, it is not possible to achieve accurate measures of separating these two
parameters so all nonadditive variance is attributed to dominance variance (sd2).

A Strategic Approach: GenAI in EducationPeter 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.
