What are three major operating characteristics of air filters? Solution Characteristics of Air Filters: 1. The material of the air filters attracts the particles in the air, so that they get stick to it, and does not pass through it. Sometimes an absorbent like charcoal may be also used with the filter material to abosrb the dust. 2. The performance depends on the ability to arrest the movement of the particles but allowing the air, so their design varies as per the requirement. Some high performance filters can filter very small particles. 3. Some filters may be made reusable with the rewashing, but they are very less common. Three common types of air filters are: (a)Fibreglass Filters: They use fibreglass layers to form the filter media. (b) Polyester and pleated filters they have higher air resistance than fibreglass but can stop smaller size particles as well. (c) High efficiency particulate arrestance (HEPA) filters. Very fine particles can be arrested by such filters. It filters 99.97 percent of all particles of size 0.3 microns or larger..

The most general problem of todays environment is the presence of dust. The dust stability in air will lead to instability in human routine in the form of health disorders. The filtration of this kind of impurities from air is one of the best possible epidemiology and probably an economical and less expensive filtration system will further help to overcome this situation. The work in this project puts its concentration on the above mentioned factors. An air filter produced form the very often fetch of simple materials is designed, analyzed and fabricated. The trapezium modeled air filter with slots embedded in it, facilitate the fatigue replacement of materials after the expiry of the same. The incoming air is forced through an Exhaust fan for a faster movement of air rather than depending on the conventional method of air income. The air entering from the inlet gets protruded through different layers of filtration. The entire model, its analysis and results are discussed in the below work. Dr. B. Vijaya Kumar | M. Naveen | P.

Desiccant beads are indispensable components in any compressed air system that requires dry air to operate efficiently. These beads serve as moisture-absorbing agents, removing water vapor from the compressed air and reducing the risk of corrosion, equipment damage, and productivity loss. By effectively controlling the moisture levels, desiccant beads contribute to improved air quality, increased operational efficiency, and extended equipment lifespan. Desiccant bead’s function based on the principles of adsorption, a process that involves the adhesion of water molecules to the surface of the desiccant material. The most commonly used desiccants include activated alumina, silica gel, and molecular sieves. These desiccant materials have a high affinity for water, attracting and trapping moisture within their porous structure. When compressed air passes through the desiccant bed, the moisture present in the air gets adsorbed by the desiccant beads. This results in significantly lower dew points and ensures the delivery of dry, moisture-free air downstream. It is crucial to monitor and maintain the desiccant beads' capacity, as they gradually become saturated over time and require regeneration or replacement to sustain optimal performance.

Dada la ecuacion de la conica -6x_1^2 + 20 x_1 x_2 + 8x_2^2 + 30 x_1 - 16 x_2 = 15 encontrar, por transformacion de efes, primero en traslacion y luego en rotacion Centro de la coniea Orintacion de sus ejes principales Identifiear el tipo de conica: elipse, parabola o hyoerbola Solution Ans- the problem of a vibrating string such as that of a musical instrument was studied by Jean le Rond d\'Alembert, Leonhard Euler, Daniel Bernoulli, and Joseph-Louis Lagrange.[4][5][6][7] In 1746, d’Alembert discovered the one-dimensional wave equation, and within ten years Euler discovered the three-dimensional wave equation.[8] The Euler–Lagrange equation was developed in the 1750s by Euler and Lagrange in connection with their studies of the tautochrone problem. This is the problem of determining a curve on which a weighted particle will fall to a fixed point in a fixed amount of time, independent of the starting point. Lagrange solved this problem in 1755 and sent the solution to Euler. Both further developed Lagrange\'s method and applied it to mechanics, which led to the formulation ofLagrangian mechanics. Fourier published his work on heat flow in Théorie analytique de la chaleur (The Analytic Theory of Heat),[9] in which he based his reasoning on Newton\'s law of cooling, namely, that the flow of heat between two adjacent molecules is proportional to the extremely small difference of their temperatures. Contained in this book was Fourier\'s proposal of hisheat equation for conductive diffusion of heat. This partial differential equation is now taught to every student of mathematical physics. Example[edit] For example, in classical mechanics, the motion of a body is described by its position and velocity as the time value varies. Newton\'s laws allow (given the position, velocity, acceleration and various forces acting on the body) one to express these variables dynamically as a differential equation for the unknown position of the body as a function of time. In some cases, this differential equation (called an equation of motion) may be solved explicitly. An example of modelling a real world problem using differential equations is the determination of the velocity of a ball falling through the air, considering only gravity and air resistance. The ball\'s acceleration towards the ground is the acceleration due to gravity minus the acceleration due to air resistance. Gravity is considered constant, and air resistance may be modeled as proportional to the ball\'s velocity. This means that the ball\'s acceleration, which is a derivative of its velocity, depends on the velocity (and the velocity depends on time). Finding the velocity as a function of time involves solving a differential equation and verifying its validity. Types[edit] Differential equations can be divided into several types. Apart from describing the properties of the equation itself, these classes of differential equations can help inform the choice of approach to a solution. Commonly us.

Assume that a new oxygen-transport protein has been discovered in certain invertebrate animals. X-ray diffraction of the deoxy protein reveals that it has the dimeric structure shown in the figure below in panel (a) with a salt bridge between residues histidine 13 and aspartic acid 85. The two monomers interact by salt bridges between the C- and N-termini. The O2-binding site lies between the two iron atoms shown, which are rigidly linked to helices A and C (see panel (b)). In the deoxy form, the space between the iron atoms is too small to hold O2, and so the Fe atoms must be forced apart when O2 is bound. Answer the following questions, explaining your answer in each case in terms of the structure shown below. Is this molecule likely to show cooperative oxygen binding? Is this molecule likely to exhibit a Bohr effect? Helix Helix Fe Fe a 13 13 Fe Fe oxygen molecule Helix el IX Helix Helix (a) Structure of deoxy protein (b)Detail of the oxygen-binding N and C denote N-termini site in the oxyform. and C-termini. The dyad axis (c) is perpendicular to this page. Solution Yes, this molecule likely to show cooperative oxygen binding. Binding of oxygen to one of the monomers will involve pushing away of the Fe atoms, and also a pushing away of the A and C helix. The A and C helix of the other monomer are joined by salt bridges and widening of the gap between the two helices on one monomer (lets say R state; i.e. which has bound Oxygen) will favor the widening of the gap between the two helices on the other monomer (lets say T state; i.e. which has not bound oxygen). This widening of the gap between the two helices will favor the binding of oxygen to the Fe atoms with greater ease (hence, the transition from T to R state), signifying cooperativity. Yes, the molecule may likely exhibit Bohr effect as well. When, in the presence of CO2 or otherwise, the pH falls, Histidine will be favored to exist in the protonated state and the salt bridge will be stronger. This shall make the widening of the gap between the two helices difficult and oxygen will not be able to bind (T state!). Conversely, when pH rises, the R state will be favored..

Describe in words the phylogenetic relationships among Eusthenopteron, Tiktaalik, a modern salamander, and you. Be sure to describe which are more closely related to each other. Solution Answer: Eusthenopteron, Tiktaalik, modern salamander and humans mark a morphological transition from fishes to tetrapods and to bipedals like humans. Eusthenopteron was a large fish (predatory) that were mainly marine, but also inhabited shallow esturine waters. Eusthenopteron share its phylogenetic relationships with early tetrapods on the basis of its folded dentition. Moreover, its pectoral and pelvic fins were homologous to radius, ulna, tibia and fibula of modern tetrapods. Tiktaalik (also called transitional fossil) marked the transition from aquatic to land in early tetrapods. Although being a fish, it exhibited morphological characters similar to transition from water to terrestrial life. It lacks the operculum which converts the bony connection between head and body to a more flexible neck like structure. This allowed their head movements out of water. Modern salamaders are tetrapod amphibians typically characterized by appearances which are lizard like and have the unique capability of limb regeneration. They are related to modern day humans with respect to the evolution of lungs and four limbs and also in the pattern of shull development. Among the organisms mentioned above, Eusthenopteron and Tiktaalik are more closely related phylogenetically. Evidences include their fin morphology..

Which system performs better: using OFDM to service two different users simultaneously with two 20 MHz channels or using OFDMA to service these two users asynchronously using a 40 MHz channel? Can OFDMA achieve better performance than MU-MIMO? Justify your reasoning in terms of the number of simultaneous users supported, multipath mitigation, and the achievable data rate or throughput. Hint: OFDMA may allow all channels of say the 2.4 or 5 GHz bands to be used simultaneously. Solution Multiple input, multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) is the dominant air interface for 4G and 5G broadband wireless communications. It combines multiple input, multiple output (MIMO) technology, which multiplies capacity by transmitting different signals over multiple antennas, and orthogonal frequency-division multiplexing (OFDM), which divides a radio channel into a large number of closely spaced subchannels to provide more reliable communications at high speeds. Research conducted during the mid-1990s showed that while MIMO can be used with other popular air interfaces such as time division multiple access (TDMA) and code division multiple access (CDMA), the combination of MIMO and OFDM is most practical at higher data rates. MIMO-OFDM is the foundation for most advanced wireless local area network (wireless LAN) and mobile broadband network standards because it achieves the greatest spectral efficiency and, therefore, delivers the highest capacity and data throughput. Greg Raleigh invented MIMO in 1996 when he showed that different data streams could be transmitted at the same time on the same frequency by taking advantage of the fact that signals transmitted through space bounce off objects (such as the ground) and take multiple paths to the receiver. That is, by using multiple antennas and precoding the data, different data streams could be sent over different paths. Raleigh suggested and later proved that the processing required by MIMO at higher speeds would be most manageable using OFDM modulation, because OFDM converts a high-speed data channel into a number of parallel, lower-speed channels. OFDMA with 40 MHz will perform better.

What is an interface ? How is extending a class different from implementing an interface ? Solution Interface :- Interface is also one type class; it is a fully un-implemented class. It is used for creating a new type of object only by declaring set of operations of this object. So interface contains only public static final variables and public abstract methods for declaring object operations. Interface is mainly introduced to develop multiple implementation inheritance. How is extending a class different from implementing an interface ? Because a class can extend an another class. But one and only a class implements an interface. Example :- Interface I1 { } Interface I2 { } class A { } class c extends A { } class c extends A implements I1,I2 { }.

what are the consequences of HWE on allele and genotype frequencies? Solution The Hardy-Weinberg law states that the proportions or frequencies of the alleles in gene pool of a population remain constant or at equilibrium from generation to generation unless acted upon by agents other than sexual recombination. The genotypic frequencies stabilize after one generation in proportions determined by allelic frequencies. The Hardy-Weinberg equation provides a standard to measure the changes in allele frequencies occurring in the natural populations without this equation the change in the frequency of alleles the magnitude and direction of the alleles and the forces responsible for change in allele characteristics can not be detected. Apart from the natural selection the change in the composition of the gene pool of a population is influenced by other conditions as follows:- Mutations alter the gene pool by changing one allele in to another. Mutations are the heritable changes in the genotype and can be caused by addition or deletion of few nucleotides in a DNA molecule or segments of chromosomes or whole set of chromosomes. Mutations may occur spontaneously and randomly. The rate of spontaneous mutations is generally low but can bring about the evolutionary change because the variation is acted upon by evolutionary forces. Movement of individuals leads to the transfer of alleles in to the population and can change the gene pools. The gene flow or movement of alleles occurs due to immigration or emigration of individuals. Incase of plants the gene flow is possible through the movement of pollen between populations. The gene flow can introduce new alleles in to the populations or can change the frequency of existing alleles. The overall effect of gene flow is to decrease the difference the populations. Large population size can alter the frequencies or relative proportions of alleles in a gene pool. Population size is more important to estimate the frequency of alleles in the gene pool. A defective allele with 1% frequency in a population containing 1 million individuals the affected population would be 20,000. If few individuals of this population with the defective gene are destroyed before producing the progeny the effect on the frequency on defective allele would be negligible. In a population of 50 individuals the frequency of defective allele would be 1 in 80. Thus, the change in the gene pool takes place by chance is known as genetic drift and it plays a major role in determination of evolution of small populations. The gene pool is altered when the population is deviated by the random mating. Random mating results in the mating of population with the close neighbors and large populations contain the closely related individuals. Inbreeding is resulted due to non random mating of closely related individuals. The non random mating does not change the frequencies of alleles in the gene pool but affects the genotypic frequencies..

Three kinds of macromolecules are present in cell membranes. What are they? What larger structures do they make? What are the essential aspects of these structures that dictate their function? Solution Three kinds of macromolecules are present in cell membranes: Lipids, proteins, and carbohydrates These three macromolecules together to form a complex phospholipid bilayer in which periplasmic proteins are distributed in a mosaic manner. The large fluid mosaic structure is formed from these macromolecules composed of phospholipid bilayers with protein channels for the transport of organic & inorganic nutrients including trace metal. Normally, the essential aspects of these structures composed of \"porins, protein channels, integral proteins” that dictate their function for the selective permeability, diffusion of nutrients across the membrane into & out of the cell finally to attain homeostasis For instance, fluid mosaic model describes that two-dimensional liquid layer of cell membrane where proteins distributed like mosaic model in the phospholipid bilayer. This model mostly accepted by biologists Role of the protein molecules in this model cell membrane layers are membrane extracellular protein domains in connection to the lipid bilayer membrane. Membrane phospholipids are the molecules with hydrophillic polar heads towards the solvent such as water whereas hydrophobic tail located towards the center of the layer and this bilayer formed by micelles, as fatty acids possess one polar associated with another nonpolar head. Cell membrane possesses a property known as selective permeability. Cell membrane consists of phopholipid bilayer that also include several of the transmembrane proteins, ion channels etc. Small, nonpolar molecules with hydrophobic nature diffuse more easily into the cell membrane. Similarly, proteins interact and assemble themselves to form several layers of structures in our body. Small particles are such as oxygen and CO2, urea can cross the lipid bilayer easily through diffusion compared to glucose (channel mediated-sodium dependent transport into the cell), amino acids (channel mediated) and various ions etc. Atoms.
