1). The inheritance of recessive genes (disease causing) can remain .pdf
1). The inheritance of recessive genes (disease causing) can remain prevalent if presence of two
copies of an allele is disadvantageous and presence of one copy of the allele may be
advantageous.
For example in case of sickle cell anaemia, two alleles may cause sickle cell anaemia but
carrying one allele is advantageous in regions where malaria is common because this single copy
of allele offers resistance against malaria. Thus, many people still carry the allele of sickle cell
anaemia, as natural selection does not remove it; this is called “balanced polymorphism.”
Thus, people carrying one copy of sickle cell disease causing allele migrated to the regions of
Africa and develops resistance to malaria parasite. They passed this protective allele to their
offspring. However, two carriers with protective allele might have a child with sickle cell
disease.
Today, the prevalence of malaria parasite is decreased well by artificial control methods. This
change in climate caused decreased number of sickle cell allele carriers.
2). Yes, the individuals homozygous for the mutation are susceptible for the sickle cell anemia,
whereas the heterozygous individuals are resistant to malaria.
3). Increased incidence of malaria causes the persistence of sickle cell allele as it increases the
fitness of an individual.

It depends on how many unique protons are adjacen.pdf
It depends on how many unique protons are adjacent to the proton(s) that you are
looking at. First, if you have an isolated proton that is not adjacent to any other protons, it will
be a singlet. A good example is a tert-butyl group. The three CH3 appear equivalent and none of
them has directly adjacent protons. The signal appears as a huge singlet that integrates to nine
protons. Doublets arise when there is a single proton next to the proton you are observing. My
favorite example of this is 2-methyl cyclohexanone. If you were to look at the CH3 group, you
would see a doublet because there is one proton on the neighboring carbon. Now for some of the
more complicated stuff: Suppose you have an ethyl ether group in your molecule. If you look at
the signal for the CH3 at the end of the chain, you have a signal which would be split by the two
protons on the next carbon over. The rule is, you get n + 1 peaks, where n is the number of
protons that are causing the splitting. Since in the case of Et there are two equivalent protons on
the CH2, you end up with 2 + 1 = 3 peaks, a triplet. The peaks should appear in a 1:2:1 height
ratio. Now suppose we look at the CH2 protons, which have a different chemical shift. In this
case, the protons are adjacent to three equivalent protons (on the methyl group). As a result you
get 3 + 1 = 4 peaks, a quartet. In this case, the peaks will show up in a 1:3:3:1 height ratio.

Security has been the number 1 issue for any IT industry and organiz.pdf
Security has been the number 1 issue for any IT industry and organizations have to adopt to the
new security technology catering to their needs from time to time. Though the DBMS itself has
security features, however multiple features like SQL injection protection,vulnerability
assessments,user control activity etc features are still left unattended.Let us now see what are the
emerging security technologies in the protection of databases.
Protecting sensitive and confidential data of the organization is getting more and more difficult
as new threats are discovered. Database is a ever growing thing and their is a chance for the
presence of loopholes.The main problem when it comes to databases is the DBA should have the
view of all the data as a central controller and he should scour the database for any
vulnerabilities.VMT ( vulnerability management technology) is very useful to view the entire
database landscape and help the DBA to ensure his data of any exploitations.
Once the landscape is clearly scene a series of scans can be administered to see where the
sensitive or high protection needed data is present and using DAM technology (Database
monitoring technology) it is easy to protect the sensitive data effectively and add patches
wherever required. The technology also generates warnings and alerts on violations as it
monitors the database in real time. Most useful feature of using DAM is to collect information
about the use of DBMS which can help in audit purposes.It also provides database firewalls
which is similar to web application firewalls which can discard malicious activity,filter the
queries and have blacklist and whitelist feature as well.
Yes, software security is what people are after.However hardware security is needed wherever
software security cant protect.Nowadays cloud computing has emerged as the most powerful
technology where every information we have will be stored in remote servers and can be
accessed by us whenever needed. But the question arises about the security of the data. So, one
wonderful solution for this involves a hardware security systems where the dedicated chips are
inserted in the servers which can be overridden by the third parties via malicious attacks.These
chips provide security and security verification and makes the cloud system safe and reliable.
It is an obvious fact that providing hardware security for the device gives more confidence that
having a software security solution which can be accessed remotely and malware can come and
reside anywhere, But in these hardware systems there are only designated tasks and limited space
and malware cant even hide there.
Hardware security chips also manage physical problems.For example if there are fluctuations in
temperature,problems in electrical flow and breach of the casting then these chips can erase the
sensitive data.In this way these chips can protect themselves. There is also a facilty of every chip
having a unique digital signature and the user whe.

Kidneys are the chief excretory organs of the body. They excrete the.pdf
Kidneys are the chief excretory organs of the body. They excrete the unwanted nitrogenous
substances through urine. The chief nitrogenous wastes that are excreted through urine are
Kidneys also excrete harmful substances like toxins, drugs, heavy metals.
By excreting the waste materials through urine, the kidneys maintain homeostasis of the body.
Urine formation:
Urine is formed by the absorption of some substances into the blood and secretion of some
substances into the lumen of renal tubules. This process of urine formation occurs starting from
the glomerulus, Bowman’s capsule, along the renal tubule into the collecting duct. Urine
formation involves three main processes. They are:
Glomerular filtration:
Net filtration pressure = glomerular capillary pressure - osmotic pressure + hydrostatic pressure.
The filtrate enters the Bowman’s capsule and then into the renal tubule of nephron.
Tubular reabsorption:
As the substances are selectively reabsorbed into the blood, this reabsorption is also known as
selective reabsorption.
Tubular secretion:
Thus, urine is formed by glomerular filtration, tubular reabsorption, and tubular secretion.
Excretory substances are secreted into the lumen of renal tubules.
Useful substances are reabsorbed into the capillaries surrounding the renal tubules.

In internetworking, Multiplexing is a process in which multiple data.pdf
In internetworking, Multiplexing is a process in which multiple data channels are combined into
a single data or physical channel at the source. Multiplexing can be implemented at any of the
OSI layers. Conversely, demultiplexing is the process of separating multiplexed data channels at
the destination. In this way student data & class assignment data can be combined & separated.
Types of Multiplexing
There are two basic forms of multiplexing used:
Time Division Multiplexing
Time Division Multiplexing works by the multiplexor collecting and storing the incoming
transmissions from all of the slow lines connected to it and allocating a time slice on the fast link
to each in turn. The messages are sent down the high speed link one after the other. Each
transmission when received can be separated according to the time slice allocated.
Theoretically, the available speed of the fast link should at least be equal to the total of all of the
slow speeds coming into the multiplexor so that its maximum capacity is not exceeded.
Two ways of implementing TDM are:
Synchronous TDM
Synchronous TDM works by the muliplexor giving exactly the same amount of time to each
device connected to it. This time slice is allocated even if a device has nothing to transmit. This
is wasteful in that there will be many times when allocated time slots are not being used.
Therefore, the use of Synchronous TDM does not guarantee maximum line usage and efficiency.
Synchronous TDM is used in T1 and E1 connections.
Asynchronous TDM
Asynchronous TDM is a more flexible method of TDM. With Asynchronous TDM the length of
time allocated is not fixed for each device but time is given to devices that have data to transmit.
This version of TDM works by tagging each frame with an identification number to note which
device it belongs to. This may require more processing by the multiplexor and take longer,
however, the time saved by efficient and effective bandwidth utilization makes it worthwhile.
Asynchronous TDM allows more devices than there is physical bandwidth for.
This type of TDM is used in Asynchronous Transfer Mode (ATM) networks.
Frequency Division Multiplexing
Frequency Division Multiplexing (FDM) works by transmitting all of the signals along the same
high speed link simultaneously with each signal set at a different frequency. For FDM to work
properly frequency overlap must be avoided. Therefore, the link must have sufficient bandwidth
to be able to carry the wide range of frequencies required. The demultiplexor at the receiving end
works by dividing the signals by tuning into the appropriate frequency.
FDM operates in a similar way to radio broadcasting where a number of different stations will
broadcast simultaneously but on different frequencies. Listeners can then \"tune\" their radio so
that it captures the frequency or station they want.
FDM gives a total bandwidth greater than the combined bandwidth of the signals to be
transmitted. In order to prevent signal overlap t.
If R is the intrest percent, T is the time period , P is the princip.pdf
If R is the intrest percent, T is the time period , P is the principal amount,
intrest = P*T*R/100
Total accumulated = P + P*T*R/100 = P(1 + TR/100)
thus a linear function of time
Solution
If R is the intrest percent, T is the time period , P is the principal amount,
intrest = P*T*R/100
Total accumulated = P + P*T*R/100 = P(1 + TR/100)
thus a linear function of time.

It depends on how many unique protons are adjacen.pdf
It depends on how many unique protons are adjacent to the proton(s) that you are
looking at. First, if you have an isolated proton that is not adjacent to any other protons, it will
be a singlet. A good example is a tert-butyl group. The three CH3 appear equivalent and none of
them has directly adjacent protons. The signal appears as a huge singlet that integrates to nine
protons. Doublets arise when there is a single proton next to the proton you are observing. My
favorite example of this is 2-methyl cyclohexanone. If you were to look at the CH3 group, you
would see a doublet because there is one proton on the neighboring carbon. Now for some of the
more complicated stuff: Suppose you have an ethyl ether group in your molecule. If you look at
the signal for the CH3 at the end of the chain, you have a signal which would be split by the two
protons on the next carbon over. The rule is, you get n + 1 peaks, where n is the number of
protons that are causing the splitting. Since in the case of Et there are two equivalent protons on
the CH2, you end up with 2 + 1 = 3 peaks, a triplet. The peaks should appear in a 1:2:1 height
ratio. Now suppose we look at the CH2 protons, which have a different chemical shift. In this
case, the protons are adjacent to three equivalent protons (on the methyl group). As a result you
get 3 + 1 = 4 peaks, a quartet. In this case, the peaks will show up in a 1:3:3:1 height ratio.

Security has been the number 1 issue for any IT industry and organiz.pdf
Security has been the number 1 issue for any IT industry and organizations have to adopt to the
new security technology catering to their needs from time to time. Though the DBMS itself has
security features, however multiple features like SQL injection protection,vulnerability
assessments,user control activity etc features are still left unattended.Let us now see what are the
emerging security technologies in the protection of databases.
Protecting sensitive and confidential data of the organization is getting more and more difficult
as new threats are discovered. Database is a ever growing thing and their is a chance for the
presence of loopholes.The main problem when it comes to databases is the DBA should have the
view of all the data as a central controller and he should scour the database for any
vulnerabilities.VMT ( vulnerability management technology) is very useful to view the entire
database landscape and help the DBA to ensure his data of any exploitations.
Once the landscape is clearly scene a series of scans can be administered to see where the
sensitive or high protection needed data is present and using DAM technology (Database
monitoring technology) it is easy to protect the sensitive data effectively and add patches
wherever required. The technology also generates warnings and alerts on violations as it
monitors the database in real time. Most useful feature of using DAM is to collect information
about the use of DBMS which can help in audit purposes.It also provides database firewalls
which is similar to web application firewalls which can discard malicious activity,filter the
queries and have blacklist and whitelist feature as well.
Yes, software security is what people are after.However hardware security is needed wherever
software security cant protect.Nowadays cloud computing has emerged as the most powerful
technology where every information we have will be stored in remote servers and can be
accessed by us whenever needed. But the question arises about the security of the data. So, one
wonderful solution for this involves a hardware security systems where the dedicated chips are
inserted in the servers which can be overridden by the third parties via malicious attacks.These
chips provide security and security verification and makes the cloud system safe and reliable.
It is an obvious fact that providing hardware security for the device gives more confidence that
having a software security solution which can be accessed remotely and malware can come and
reside anywhere, But in these hardware systems there are only designated tasks and limited space
and malware cant even hide there.
Hardware security chips also manage physical problems.For example if there are fluctuations in
temperature,problems in electrical flow and breach of the casting then these chips can erase the
sensitive data.In this way these chips can protect themselves. There is also a facilty of every chip
having a unique digital signature and the user whe.

Kidneys are the chief excretory organs of the body. They excrete the.pdf
Kidneys are the chief excretory organs of the body. They excrete the unwanted nitrogenous
substances through urine. The chief nitrogenous wastes that are excreted through urine are
Kidneys also excrete harmful substances like toxins, drugs, heavy metals.
By excreting the waste materials through urine, the kidneys maintain homeostasis of the body.
Urine formation:
Urine is formed by the absorption of some substances into the blood and secretion of some
substances into the lumen of renal tubules. This process of urine formation occurs starting from
the glomerulus, Bowman’s capsule, along the renal tubule into the collecting duct. Urine
formation involves three main processes. They are:
Glomerular filtration:
Net filtration pressure = glomerular capillary pressure - osmotic pressure + hydrostatic pressure.
The filtrate enters the Bowman’s capsule and then into the renal tubule of nephron.
Tubular reabsorption:
As the substances are selectively reabsorbed into the blood, this reabsorption is also known as
selective reabsorption.
Tubular secretion:
Thus, urine is formed by glomerular filtration, tubular reabsorption, and tubular secretion.
Excretory substances are secreted into the lumen of renal tubules.
Useful substances are reabsorbed into the capillaries surrounding the renal tubules.

In internetworking, Multiplexing is a process in which multiple data.pdf
In internetworking, Multiplexing is a process in which multiple data channels are combined into
a single data or physical channel at the source. Multiplexing can be implemented at any of the
OSI layers. Conversely, demultiplexing is the process of separating multiplexed data channels at
the destination. In this way student data & class assignment data can be combined & separated.
Types of Multiplexing
There are two basic forms of multiplexing used:
Time Division Multiplexing
Time Division Multiplexing works by the multiplexor collecting and storing the incoming
transmissions from all of the slow lines connected to it and allocating a time slice on the fast link
to each in turn. The messages are sent down the high speed link one after the other. Each
transmission when received can be separated according to the time slice allocated.
Theoretically, the available speed of the fast link should at least be equal to the total of all of the
slow speeds coming into the multiplexor so that its maximum capacity is not exceeded.
Two ways of implementing TDM are:
Synchronous TDM
Synchronous TDM works by the muliplexor giving exactly the same amount of time to each
device connected to it. This time slice is allocated even if a device has nothing to transmit. This
is wasteful in that there will be many times when allocated time slots are not being used.
Therefore, the use of Synchronous TDM does not guarantee maximum line usage and efficiency.
Synchronous TDM is used in T1 and E1 connections.
Asynchronous TDM
Asynchronous TDM is a more flexible method of TDM. With Asynchronous TDM the length of
time allocated is not fixed for each device but time is given to devices that have data to transmit.
This version of TDM works by tagging each frame with an identification number to note which
device it belongs to. This may require more processing by the multiplexor and take longer,
however, the time saved by efficient and effective bandwidth utilization makes it worthwhile.
Asynchronous TDM allows more devices than there is physical bandwidth for.
This type of TDM is used in Asynchronous Transfer Mode (ATM) networks.
Frequency Division Multiplexing
Frequency Division Multiplexing (FDM) works by transmitting all of the signals along the same
high speed link simultaneously with each signal set at a different frequency. For FDM to work
properly frequency overlap must be avoided. Therefore, the link must have sufficient bandwidth
to be able to carry the wide range of frequencies required. The demultiplexor at the receiving end
works by dividing the signals by tuning into the appropriate frequency.
FDM operates in a similar way to radio broadcasting where a number of different stations will
broadcast simultaneously but on different frequencies. Listeners can then \"tune\" their radio so
that it captures the frequency or station they want.
FDM gives a total bandwidth greater than the combined bandwidth of the signals to be
transmitted. In order to prevent signal overlap t.

If R is the intrest percent, T is the time period , P is the principal amount,
intrest = P*T*R/100
Total accumulated = P + P*T*R/100 = P(1 + TR/100)
thus a linear function of time
Solution
If R is the intrest percent, T is the time period , P is the principal amount,
intrest = P*T*R/100
Total accumulated = P + P*T*R/100 = P(1 + TR/100)
thus a linear function of time.

Operation Blue Star - Saka Neela Tara
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.
Digital Tools and AI for Teaching Learning and Research
This Presentation in details discusses on Digital Tools and AI for Teaching Learning and Research
A Strategic Approach: GenAI in Education
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.
