Mobile IP:
1) Mobile IP(MIP) is an Internet Engineering Task Force(IETF) standard communications
protocol.
2) This is designed to allow mobile device users to move from one network to another while
maintaining a permanent IP address.
3) Mobile IP for IPv4 is described in IETF RFC 5944 and extensions are defined in IETF RFC
4721.
4) Mobile IPv6 the IP mobility implementation for the next generation of the Internet Protocol
IPv6 is described in RFC 6275.
Advantages of using Mobile IP
• It allows fast, continuous lowcost access to corporate networks in remote areas where there
is no public telephone system or cellular coverage.
• It supports a wide range of applications from Internet access and email to ecommerce.
• Users can be permanently connected to their Internet provider and charged only for the data
packets that are sent and received.
• Lower equipment and utilization costs for those requiring reliable highspeed data connections
in remote locations worldwide.
• A user can take a palmtop or laptop computer anywhere without losing the connection to the
home network.
• Mobile IP finds local IP routers and connects automatically. It is phonejack and wirefree.
• Other than mobile nodes/routers, the remaining routers and hosts will still use current IP.
Mobile IP leaves transport and higher protocols
unaffected.
• Authentication is performed to ensure that rights are being protected.
• Mobile IP can move from one type of medium to another without losing connectivity. It is
unique in its ability to accommodate heterogeneous
mobility in addition to homogenous mobility.
Disadvantage of Mobile IP
• There is a routing inefficiency problem caused by the “triangle routing” formed by the home
agent, correspondent host and the foreign agent.
• Security risks are the most important problem facing Mobile IP. Besides the traditional security
risks with
IP, one has to worry about faked careof addresses.
• Another issue related to the security is how to make Mobile IP coexist with the security
features coming in
use within the Internet.
Characteristics of Mobile IP (Baseline Requirements)
• Compatibility: A new standard cannot require changes for applications or network protocols
already in use.
• Transparency: Mobility should remain “invisible” for many higher layer protocols and
applications.
• Scalability and efficiency: Introducing a new mechanism into the Internet must not degrade the
efficiency of the network.
• Security: All messages used to transmit information to another node about the location of a
mobile node must be authenticated to protect against remote redirection attacks
The Mobile IP in Wireless Networks
• new proposed standard of the IETF designed to support mobile users .
• new Internet standard for the Web and private networks.
• currently two standards one to support the current IPv4 one for the upcoming IPv6.
• One of the big requirements on the new standard is that it should support both ordinary and
wireless network
• The big issue is.
5G is the fifth generation technology standard for cellular networks, which cellular phone companies began deploying worldwide in 2019, the planned successor to the 4G networks which provide connectivity to most current cellphones.
5G is the short for fifth generation, a mobile broadband technology that is in the early stages of works and likely to be in place six to seven years from now.
A 5G network will be able to handle 10,000 times more call and data traffic than the current 3G or 4G network.
Data download speeds on 5G networks are likely to be several hundred times more than 4G.
5G mobile technology will change the means to use cell phones within very high bandwidth.

IOT and its communication models and protocols.pdfMD.ANISUR RAHMAN
A brief visual description of the Internet of Things and how it works. Then, we will learn about the communication models of IoT and how their structure defines them. Then we will go for the IoT protocols and know about different types of protocols. At last, we will see some applications of IoT.
This is the second part of my 5G project which consists of the architecture structure of 5G. What all it consists of, what all technologies it uses, what all layers it contain etc.
We are looking at the future of technology that has the structure of Nanocore, beneficial for future applications.
In this presentation, we embark on a journey through the evolution of cellular networks, tracing their roots from 1G to the current pinnacle of technology, 5G. We delve into the intricacies of 5G, exploring its foundational principles, technical workings, and the myriad advantages it brings, from lightning-fast data speeds to enabling groundbreaking applications in augmented reality, the Internet of Things, and beyond. However, no exploration of 5G is complete without addressing concerns and misconceptions. We confront conspiracy theories surrounding 5G, including alleged health risks and unfounded associations with the COVID-19 pandemic. By the end, participants will gain a holistic understanding of 5G's transformative potential, appreciating its benefits while dispelling myths that may cloud its advancement.

What property of proteins us used to separate them in HICHydrophob.pdfanandhomeneeds
What property of proteins us used to separate them in HIC
Hydrophobic interaction chromatography (HIC) isolates Proteins in light of their hydrophobicity,
and is regularly utilized as a middle stride as a part of a cleaning plan. Proteins are bound to a
stationary stage in a high ionic quality cushion and, along these lines, HIC can commonly be
performed instantly after particle trade chromatography with no cradle trade or weakening
required. HIC is likewise usually performed after an ammonium sulfate precipitation, a strategy
that can be utilized to rapidly expel proteins by accelerating a few, yet not all, proteins with salt.
HIC is infrequently material in early strides of a purging plan or as a last stride in the expulsion
of follow polluting influences from the protein of intrigue.
====================================================
Described mobile and stationary phase in HIC
Hydrophobic association chromatography (HIC) is an other option to turned around stage
chromatography for abusing the hydrophobic properties of proteins.
The expansion of a salt to the mobile stage support and test arrangement advances protein-
medium connections. The proteins are adsorbed to the medium in a mobile stage containing a
high grouping of salt. The vast majority of the bound proteins are viably desorbed by essentially
washing with water or a weaken, close impartial support. Since HIC utilizes a more polar, less
denaturing environment than RPLC, it is getting to be well known for protein filtration, regularly
in blend with particle trade or gel filtration chromatography.

The substrate in urease test is urea.The end products in urease te.pdfanandhomeneeds
The substrate in urease test is urea.
The end products in urease test are urea, carbondioxide and water
(NH2)2 CO+2H2O CO2+ H2O + 2NH3
Urease test is used to determine the ability of an organism to hydrolyse urea into ammonia and
carbon dioxide. The ammonia formed during the reaction turns the media into alkaline, which is
indicated by phenol red, changing its color from light orange (at pH 6.8) to pink (at pH 8.1).
Rapid urease positive organisms like Helicobacter pylori, turns the medium pink within 24
hours. Weakly positive organisms take several days, whereas negative organisms produce no
colour.
Rapid Urease Test (RUT) is a popular and simple test which uses the above principle , for
detecting the presence of Helicobacter pylori on gastric mucosa. The test is also known as CLO
test (Campylobacter like organism test). It is also useful in identifying several genera and species
of Enterobacteriaceae like Proteus spp, Klebsiella spp and Yersinia spp. Also for identifying
Cryptococcus spp and Brucella spp.

D(ANSWER)Polycrystalline or multicrystalline materials, or polycry.pdfanandhomeneeds
D(ANSWER)
Polycrystalline or multicrystalline materials, or polycrystals are solids that are composed of
many crystallites of varying size and orientation. Crystallites are also referred to as grains. They
are small or even microscopic crystals and form during the cooling of many materials. Their
orientation can be random with no preferred direction, called random texture, or directed,
possibly due to growth and processing conditions. Fiber texture is an example of the latter. The
areas where crystallite grains meet are known as grain boundaries.
Grain boundaries are interfaces where crystals of different orientations meet. A grain boundary is
a single-phase interface, with crystals on each side of the boundary being identical except in
orientation. The term \"crystallite boundary\" is sometimes, though rarely, used. Grain boundary
areas contain those atoms that have been perturbed from their original lattice sites, dislocations,
and impurities that have migrated to the lower energy grain boundary.
Treating a grain boundary geometrically as an interface of a single crystal cut into two parts, one
of which is rotated, we see that there are five variables required to define a grain boundary. The
first two numbers come from the unit vector that specifies a rotation axis. The third number
designates the angle of rotation of the grain. The final two numbers specify the plane of the grain
boundary (or a unit vector that is normal to this plane).
Grain boundaries disrupt the motion of dislocations through a material. Dislocation propagation
is impeded because of the stress field of the grain boundary defect region and the lack of slip
planes and slip directions and overall alignment across the boundaries. Reducing grain size is
therefore a common way to improve strength, often without any sacrifice in toughness because
the smaller grains create more obstacles per unit area of slip plane. This crystallite size-strength
relationship is given by the Hall-Petch relationship. The high interfacial energy and relatively
weak bonding in grain boundaries makes them preferred sites for the onset of corrosion and for
the precipitation of new phases from the solid.
Grain boundary migration plays an important role in many of the mechanisms of creep. Grain
boundary migration occurs when a shear stress acts on the grain boundary plane and causes the
grains to slide. This means that fine-grained materials actually have a poor resistance to creep
relative to coarser grains, especially at high temperatures, because smaller grains contain more
atoms in grain boundary sites. Grain boundaries also cause deformation in that they are sources
and sinks of point defects. Voids in a material tend to gather in a grain boundary, and if this
happens to a critical extent, the material could fracture.
During grain boundary migration, the rate determining step depends on the angle between two
adjacent grains. In a small angle dislocation boundary, the migration rate depends on vac.

Answer The major objective of implementing a health information man.pdfanandhomeneeds
Answer: The major objective of implementing a health information management system is to
automate and streamline the process of capturing, processing, maintaining/storing, and analysing
the information related to health and health case. This information is just not related to one thing,
but covers many aspects and involves many stakeholders. It is related to patient\'s profile
(personal as well as medical), treatment prescribed to him/her, doctor\'s and health officials\'
profile, other relevant health records like details and results of various tests (if performed),
accounting, health related human resources among many other things.
Out of these, the most important part is - information related to patient\'s profile, treatment
prescribed, and other relevant health records. Collectively, this is termed as Electronic Health
Records (EHRs) which lies at the core of any HIMS. The nature and kind of information that is
present in EHRs is very personal and sensitive. Hence, ensuring security, privacy and
confidentiality of EHRs in HMIS should be utmost concern because if this information is
breached or comromised, its after-effects can be desasterous.
Hence, while implementing any HMIS, it is very critical to think of required and relevant
security and data protection mechanisms and make provisions for them into the system.

The key assumptions made by the Hadoop Distributed File System(HDFS).pdfanandhomeneeds
The key assumptions made by the Hadoop Distributed File System(HDFS) approach are:
1. High Volume: The volume of data in HDFS is expected to be really large, some like being
measured in terabytes or even petabytes.
2. High Availability: The cluster can contain thousands of file servers, and some of them may be
down(unavailable) at some given instance.
3. Reliable Communication: Communication is reliable among working machines.
4. The filesystem is not designed for interactive operations, instead, we prefer high throughput
over low latency.
5. Servers are distributed among racks and data centers, to ensure redundancy, and therefore
availability.

Environmental conditions play a key role in defining the function an.pdfanandhomeneeds
Environmental conditions play a key role in defining the function and distribution of plants, in
combination with other factors. Changes in long term environmental conditions that can be
collectively coined climate change are known to have had enormous impacts on plant diversity
patterns in the future and are seen as having significant current impacts. It is predicted that
climate change will remain one of the major drivers of biodiversity patterns in the future.
The Earth has experienced a constantly changing climate in the time since plants first evolved. In
comparison to the present day, this history has seen Earth as cooler, warmer, drier and wetter,
and CO2 (carbon dioxide) concentrations have been both higher and lower. These changes have
been reflected by constantly shifting vegetation, for example forest communities dominating
most areas in interglacial periods, and herbaceous communities dominating during glacial
periods. It has been shown that past climatic change has been a major driver of the processes of
speciation and extinction. The best known example of this is the Carboniferous Rainforest
Collapse which occurred 350 million years ago. This event decimated amphibian populations
and spurred on the evolution of reptiles
Greenhouse effect - the mechanism
The sun radiates solar energy on earth. The larger part of this energy (45%) is radiated back into
space. Greenhouse gases in the atmosphere contribute to global warming by adsorption and
reflection of atmospheric and solar energy. This natural phenomenon is what we call the
greenhouse effect. It is agreed that the greenhouse effect is correlated with global temperature
change. The primary greenhouse gases in the Earth’s atmosphere are water vapor, carbon
dioxide, methane, nitrous oxide, and ozone
Mechanism of global warming:
i. The incoming radiation from the Sun is mostly in the form of visible light and nearby
wavelengths, largely in the range 0.2 – 4 1m, corresponding to the Sun’s radioactive temperature
of 6,000 K. Almost half the radiation is in the form of “visible” light, which our eyes are adapted
to use.
ii. About 50% of the Sun’s energy is absorbed at the earth’s surface and the rest is reflected or
absorbed by the atmosphere. The reflection of light back into space – largely by clouds – does
not much affect the basic mechanism; this light, effectively, is lost to the system.
iii (a) Earth absorbs most of the sunlight it receives; The absorbed energy warms the surface; (b)
Earth then emits the absorbed light’s energy as infrared light; (c) greenhouse gases absorb a lot
of the infrared light before it can leave our atmosphere; (d) being absorbed slows the rate at
which energy escapes to space; and (e) the slower passage of energy heats up the atmosphere,
water, and ground. By increasing the amount of greenhouse gases in the atmosphere, humans are
increasing the atmosphere’s absorption of infrared light, thereby warming Earth and disrupting
global climate patterns.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

Mobile IP1) Mobile IP(MIP) is an Internet Engineering Task Force(.pdf
1. Mobile IP:
1) Mobile IP(MIP) is an Internet Engineering Task Force(IETF) standard communications
protocol.
2) This is designed to allow mobile device users to move from one network to another while
maintaining a permanent IP address.
3) Mobile IP for IPv4 is described in IETF RFC 5944 and extensions are defined in IETF RFC
4721.
4) Mobile IPv6 the IP mobility implementation for the next generation of the Internet Protocol
IPv6 is described in RFC 6275.
Advantages of using Mobile IP
• It allows fast, continuous lowcost access to corporate networks in remote areas where there
is no public telephone system or cellular coverage.
• It supports a wide range of applications from Internet access and email to ecommerce.
• Users can be permanently connected to their Internet provider and charged only for the data
packets that are sent and received.
• Lower equipment and utilization costs for those requiring reliable highspeed data connections
in remote locations worldwide.
• A user can take a palmtop or laptop computer anywhere without losing the connection to the
home network.
• Mobile IP finds local IP routers and connects automatically. It is phonejack and wirefree.
• Other than mobile nodes/routers, the remaining routers and hosts will still use current IP.
Mobile IP leaves transport and higher protocols
unaffected.
• Authentication is performed to ensure that rights are being protected.
• Mobile IP can move from one type of medium to another without losing connectivity. It is
unique in its ability to accommodate heterogeneous
mobility in addition to homogenous mobility.
Disadvantage of Mobile IP
• There is a routing inefficiency problem caused by the “triangle routing” formed by the home
agent, correspondent host and the foreign agent.
• Security risks are the most important problem facing Mobile IP. Besides the traditional security
risks with
IP, one has to worry about faked careof addresses.
2. • Another issue related to the security is how to make Mobile IP coexist with the security
features coming in
use within the Internet.
Characteristics of Mobile IP (Baseline Requirements)
• Compatibility: A new standard cannot require changes for applications or network protocols
already in use.
• Transparency: Mobility should remain “invisible” for many higher layer protocols and
applications.
• Scalability and efficiency: Introducing a new mechanism into the Internet must not degrade the
efficiency of the network.
• Security: All messages used to transmit information to another node about the location of a
mobile node must be authenticated to protect against remote redirection attacks
The Mobile IP in Wireless Networks
• new proposed standard of the IETF designed to support mobile users .
• new Internet standard for the Web and private networks.
• currently two standards one to support the current IPv4 one for the upcoming IPv6.
• One of the big requirements on the new standard is that it should support both ordinary and
wireless network
• The big issue is to solve the overlapping between different networks—a user should be able to
move between different networks without packet losses.
• The solution proposed by a working group within the IETF suggests that the mobile node
should use two different IP addresses: a fixed home addressa careof address(COA),that changes
at each point of attachment.
• The solution requires two additional components
i) home agent (HA)
ii) foreign agent (FA)
