Impact of absorption on transmission ranges :
In general the sound, light needs a medium to travel along the desination. Witht the transmission
there might be some level of difference or the deprecation at the destination and source
comparitively. This ranges from the level, range, medium and all other factors. These also vary
extensively based on the distances greater than about a hundred meters from the source. This
variation is caused by changes in weather conditions and by topographical features such as
ground cover, hills and other obstacles between the source and the receiver.
There are several important factors which affect the propagation such as geometric spreading,
atmospheric effects, and surface effects as discussed below :
a) Geometric Spreading :
This generally refers to the spreading of energy as a result of the expansion of the wavefronts.
Geometric spreading is merely independent of FREQUENCY and has a major effect in almost
all the propagation situations.
b) Air Absorption :
In general there are two types where the energy is absorbed by the atmosphere. These are
molecular relaxation and viscosity effects. High frequencies are absorbed more than low. The
amount of ABSORPTION depends on the temperature and humidity of the atmosphere.
c) Wind and Temperature Gradients :
The speed that the energy propagates in a gas depends on the temperature of the gas. Higher
temperatures produce higher speeds of sound. Since the temperature of the atmosphere is not
uniform there are local variations in the sound speed. For example, under normal conditions the
atmosphere is cooler at higher altitudes. This results in the waves being \'bent\' upwards. This
will result in the formation of a shadow zone, which is a region in which sound does not
penetrate. In reality some sound will enter this zone due to scattering. Scattering occurs when
sound waves are propagating through the atmosphere and meet a region of inhomogeneity and
some of their energy is re-directed into many other directions.
d) Ground Absorption :
This is to be noted in general as the energy is propagating over the ground, and then the
ATTENUATION will occur due to acoustic energy losses on REFLECTION. These losses will
depend on the surface. Smooth, hard surfaces will produce little ABSORPTION whereas thick
grass may result in sound levels being reduced by up to about 10 dB per 100 meters at 2000 Hz.
High frequencies are generally attenuated more than low frequencies.
These are some of the effects or the types where the absorption impacts the transmission of the
data or the energy from the source to the destination.
Hope this is helpful.

Many molecules contain bonds that fall between the extremes of ionic and covalent
bonds. The difference between the electronegativities of the atoms in these molecules is large
enough that the electrons aren\'t shared equally, and yet small enough that the electrons aren\'t
drawn exclusively to one of the atoms to form positive and negative ions. The bonds in these
molecules are said to be polar, because they have positive and negative ends, or poles, and the
molecules are often said to have a dipole moment. for Eg : HCl molecules, for example, have a
dipole moment because the hydrogen atom has a slight positive charge and the chlorine atom has
a slight negative charge. Because of the force of attraction between oppositely charged particles,
there is a small dipole-dipole force of attraction between adjacent HCl molecules. non-polar
molecule has it\'s electron density shifted by a charged molecule, i.e., if a positively charged
species is brought near a species with an evenly distributed charge, the electrons go towards the
side where the positive species is, and away from the opposite side, creating an artificial dipole.
Eg : a helium atom is perfectly symmetrical. But movement of the electrons around the nuclei of
a pair of neighboring helium atoms can become synchronized so that each atom simultaneously
obtains an induced dipole moment.

Scientific approaches have been defined to depict the methods to study animal behaviour. These
methods help in understanding not only animal behaviour but also enhance the understanding of
an investigator in order to ddevelop a more comprehensive scienctific approach towards
psychological facts associated with animals. These methods are discussed as below:
1. The Ethology-Technically, ethology is the study of animal/human behaviuor in its
geographical location in association with its psycho-social environment with other factors by
means of close observations. This includes observational analysis by field scans i.e. residing in
the field/animal niche by the investigator for close observations. Importantly, ethology also
comprises of a biological context with each and every aspect of human/animal behaviuor. This
represents one of the most improtant tools to study and understand animal behaviour.
2. Comparative psychology- It is a comprehensive method which includes artificially designed
algorithm based non-human in silico/in vivo animals as models with special relevance for their
corresponding human behaviuor. This implies that a pre-defined set of rules are designed for a
model and certain stimuli are given. The nature of comprehensive behaviour of the organismic
model is then recorded and analysed. This gives a clear idea about comparative psychology of an
animal with respect to humans.
3. Behavioral studies and ecology- These studies comprise of a close integration of various
behavioral aspectso an animal with its specific environment. This field of science has been raised
in a past few decades in order to enhance the psychological information about the animal
behaviour. This helps the investigator to presume the behaviuor of an animals under a stimulus
without putting the animal exactly under the stimulus based upon previous experience,
recordings and integrated information.
Thus, collectively, these set of informations can help an investigator to understand animal
behaviuor scienctifically and psycho-socially.

Ques-1Government funding is limited so that the factors are neede.pdfappsmobileshoppe
Ques-1:
Government funding is limited so that the factors are needed to consider to eliminate an
infectious disease are whether the infectious agent mode of transmission and infectious agent
etiology and disease symptoms in human beings. These factors are going to promote
\"epidemiologists\" to better control \"both nosocomial infections\", pandemic infections of
communicable disease. The possible preventive measures such as vaccination can be
implemented to eliminate the disease.
Assessment of chronic disease has not only been possible because of epidemiology but also acute
disease conditions, causes, outcome of treatment to that disease conditions is also possible by
studying the disease status in the public communities. This epidemiology study used to mainly
for those infectious diseases prevailed to a large number of populations within a geographical
area in a short period of time finally useful to implement public health policies against that
infection based on epidemiological data; for example infectious disease often prevail in a
population in 2 weeks. Example of epidemic diseases is meningococcal infections; Epidemiology
studies also useful to study the nature of pandemic diseases to monitor the health of communities
& populations; These studies are used for those diseases occurring in large number of
populations across the world in almost all geographical areas. Example is flu infections.
Ques-10:
No, we never win war on microbes because microbes can change their genome persistently &
actively through mutations when they reach the host genome. For example, HIV -1 infection
therefore, it is difficult to introduce medication to defeat this microbe
Some diseases causing bacterial spores are dormant for 1000 years also and medication is
ineffective to combat these spores due to the following reason
Bacillus subtilis produce dormant spores by sporulation ate suitable conditions and these spores
are called as endospores. These endopores have the capability to survive at extreme temperatures
followed by insufficient nutrient availability and their spore DNA is completely resistant to
mutagens such as UV light, chemicals. They are also resistant to desiccation and resistant to
extreme freezing and chemical disinfectants.
Factor-1: These endospores possess very complex diversified structure that can withstand all the
possible mutation -inducing changes. These possess structural adaptations such as exosporium,
hard spore coat and these are acts as very hard complex resistant materials, which can eliminate
digesting enzymes such as lysozymes. These endospores possess cortex composed of
peptidoglycan and it has a core wall that is present under the cortex and surrounds protoplast.
These layers potentially protect spore DNA material.
Factor-2: Core material of the spore also possesses calcium dipicolinate that enable stability of
chromosomal DNA by protecting it from oxidizing agents. Inside the core material, spore
possess DNA and it is covered .

ATTENUATION will occur due to acoustic energy losses on REFLECTION. These losses will
depend on the surface. Smooth, hard surfaces will produce little ABSORPTION whereas thick
grass may result in sound levels being reduced by up to about 10 dB per 100 meters at 2000 Hz.
High frequencies are generally attenuated more than low frequencies.
These are some of the effects or the types where the absorption impacts the transmission of the
data or the energy from the source to the destination.

Solution
Please follow the data and description :
Impact of absorption on transmission ranges :
In general the sound, light needs a medium to travel along the desination. Witht the transmission
there might be some level of difference or the deprecation at the destination and source
comparitively. This ranges from the level, range, medium and all other factors. These also vary
extensively based on the distances greater than about a hundred meters from the source. This
variation is caused by changes in weather conditions and by topographical features such as
ground cover, hills and other obstacles between the source and the receiver.
There are several important factors which affect the propagation such as geometric spreading,
atmospheric effects, and surface effects as discussed below :
a) Geometric Spreading :
This generally refers to the spreading of energy as a result of the expansion of the wavefronts.
Geometric spreading is merely independent of FREQUENCY and has a major effect in almost
all the propagation situations.
b) Air Absorption :
In general there are two types where the energy is absorbed by the atmosphere. These are
molecular relaxation and viscosity effects. High frequencies are absorbed more than low. The
amount of ABSORPTION depends on the temperature and humidity of the atmosphere.
c) Wind and Temperature Gradients :
The speed that the energy propagates in a gas depends on the temperature of the gas. Higher
temperatures produce higher speeds of sound. Since the temperature of the atmosphere is not
uniform there are local variations in the sound speed. For example, under normal conditions the
atmosphere is cooler at higher altitudes. This results in the waves being 'bent' upwards. This
will result in the formation of a shadow zone, which is a region in which sound does not
penetrate. In reality some sound will enter this zone due to scattering. Scattering occurs when
sound waves are propagating through the atmosphere and meet a region of inhomogeneity and
some of their energy is re-directed into many other directions.
d) Ground Absorption :
This is to be noted in general as the energy is propagating over the ground, and then the
ATTENUATION will occur due to acoustic energy losses on REFLECTION. These losses will
depend on the surface. Smooth, hard surfaces will produce little ABSORPTION whereas thick
