A mechanical ventilator is a machine that helps people breathe when they are not able to breathe enough on their own. The Mechanical ventilator is also called a Ventilator, Respirator, or Breathing machine. Most patients who need support from a ventilator because of a severe illness are cared for in a hospital\u2019s Intensive Care Unit (ICU). People who need a ventilator for a longer time may be in a regular unit of a hospital, a rehabilitation facility, or cared for at home.\r\n\r\n \tTo ease the work of breathing. Some people can breathe, but it is very hard. They feel short of breath and uncomfortable.\r\n \t\u00a0To breathe for a patient who is not breathing because of brain damage or injury (like coma) or high spinal cord injury or very weak muscles.\r\n \tIf a patient has had a serious injury or illness that causes breathing efforts to stop, a ventilator can be used to help the lungs breathe until the person recovers.\r\n\r\nThis description appears very simple and easy to understand even for a lay man. In clinical practice, it may not be as simple as it sounds, but is a little more. Many people including some clinicians look at a ventilator with a sense of distaste. Some feel that it is very difficult to understand and manage. The truth is far from that; it is not anything very special; one must realize that a ventilator, after all is a man made machine used worldwide by clinicians, and there should be no difficulty to understand and manage it.\r\nIn the past, Anesthesiologists were expected to know how the ventilators work, as many of them were designed on simple mechanical principles. Now, almost all the modern ventilators are microprocessors controlled (computerised) and the technology is so complex that\r\nacquiring this extra knowledge is no longer reasonable or justifiable. Now we have the new generation of specialists in every hospital known as Biomedical Engineers and they have the knowledge and maintain the machines.\r\n\r\nBased on the concept of construction a ventilator may be defined as,\r\n\u2022 \u201cA ventilator is a machine \u2013 a system of related elements designed to alter, transmit and direct the applied energy (pneumatic power or electricity) in a predetermined manner to perform a useful work, to augment or replace the patient\u2019s muscles in performing the work of breathing\u201d.\r\n\r\nBasically, any ventilator must have two components for accomplishing artificial ventilation.\r\n\r\nA control mechanism (a brain): To command what to do for ventilating the patient.\r\nA driving mechanism (a muscle): To carry out the work of ventilation as it is ordered by the control mechanism (brain).\r\n\r\nmodern ventilator\r\n\r\nCLASSIFICATION OF VENTILATORS\r\nAir movement into the lungs is provided by the contraction of respiratory muscles producing a sub atmospheric (negative) intrapleural and intra-alveolar pressures. Thus formed pressure gradient between the upper airway and the alveoli allows the air to move into the lungs. Expiration is normally passive and the natural elastic recoil of the lung tissue causes an increase in the intra-alveolar pressure to reverse the pressure gradient and allows air to flow out of the lungs.\r\nMechanical ventilation is provided either by applying a negative pressure around the chest or by generating a positive pressure above the atmospheric pressure to the upper airway.\r\nAlthough negative pressure ventilation does not require endotracheal intubation, it cannot overcome substantial increases in airway resistance or decrease in pulmonary compliance, and it also limits the access to the patient.\r\nSo by concept of construction and by priority in development, the mechanical ventilators are broadly classified into two groups, namely Negative pressure ventilators and Positive pressure ventilators.\r\nMechanical Ventilation Modes :\r\nOriginally, the method by which a ventilator accomplishes the respiratory cycle is called as a \u2018Mode\u2019 of ventilation. In other words, it must have all the four phases of the respiratory cycle namely, Inspiratory phase, Change over from inspiration to expiration, expiratory phase, and Initiation of Inspiration (Change over from expiration to inspiration). The modes that have all the four phases are known as \u201cStandard Modes\u201d (Eg: Control mode, Assist\/ Control mode). There are various newer techniques which have different characteristics and are applied in special situations may be called \u201cSpecial Modes\u201d.\r\nAfter the advent of innumerable ways to support the ventilation, it is better defined as \u201cthe method or technique by which the patient and the ventilator interact to perform the ventilatory cycle\u201d.\r\n\r\nMore precisely there are only two primary modes and the third one \u201cAssist\/ Control\u201d is a combination of the first two modes.\r\n1. Controlled Mechanical Ventilation: CMV\r\n2. Assisted Mode Ventilation: Assist\r\n3. Assist\/Control Ventilation: A\/C Mode\r\n\r\nFour out of the others in the list are only modification in the inspiratory phase namely,\r\n1. Pressure Support Ventilation: PSV\r\n2. Pressure Controlled Ventilation: PCV\r\n3. Inverse Ratio Ventilation: IRV\r\n4. Proportional Assist Ventilation: PAV\r\n\r\nAnother four in the list are only modification in the Expiratory Phase. They are,\r\n1. Zero End Expiratory Pressure: (Expiratory retard) ZEEP\r\n2. Negative End Expiratory Pressure: NEEP\r\n3. Positive End Expiratory Pressure: PEEP\r\n4. Continuous Positive Airway Pressure: CPAP ZEEP and NEEP are no longer in use\r\n\r\nThe other four modes are again not primary modes. They are named as \u201cSpecial modes of Ventilation\u201d.\r\n1. Synchronised Intermittent Mandatory Ventilation: SIMV\r\n2. Biphasic Positive Airway Pressure: BIPAP\r\n3. Airway Pressure Release Ventilation: APRV\r\n4. Minimum Mandatory Volume: MMV\r\n\r\nAVAILABLE MODES\r\nThere are two basic categories of modes: Controlled or Assisted. \r\n\r\nControlled Ventilation\r\nIn controlled ventilation, the ventilator initiates the breath and performs all the work of breathing.\r\n\r\nAssisted Ventilation\r\nIn assisted ventilation, the patient initiates and terminates all or some of the breaths, with the ventilator giving variable amount of support throughout the respiratory cycle.","headline":"Basic of Mechanical Ventilation &#8211; Mechanical Ventilation Modes","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-03-09","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/03\/modern-ventilator-300x205.jpg","height":205,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/whatsapp-group-links-list-for-mechanical-engineer/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/03/whatsapp-groups-for-mechanical-engg-300x166.jpg')"></div><span class="sr-only">link to Whatsapp Group links List For Mechanical Engineer</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/whatsapp-group-links-list-for-mechanical-engineer/">Whatsapp Group links List For Mechanical Engineer</a></p></header><div class="excerpt"><p>Whatsapp Group links List For Mechanical Engineer

For this a mechanical robot is designed. The effectiveness of this platform is shown by the platforms ability to successfully navigate itself down rows of a greenhouse, while the pesticide\r\nspraying system efficiently covers the plants evenly with spray in the set dosages.\r\nA robot which could spray chemicals under grapevine trellis was developed and experimented. From the experimental results, it was observed that the robot system made precise spraying operation and its precise operation record possible. Based on the precise operations and records, an optimum management of chemicals could be expected, that is, necessary amount of chemicals would be sprayed only at necessary considered that this robot would be able to contribute the minimum input maximum output production system by establishment of trace ability system in grape production.\r\nSuch types of robots, which are used in the agricultural fields, are called as Agrobots. Here in this module we have designed a robot, which can be controlled by using a remote for spraying the pesticides in the field or greenhouse. By the development of these agrobots lot of manual labor will also be decreased.\r\n\r\nIn this regard here is a demo model of such equipment, which performs the operation very effectively. Such types of robots, which are used in the agricultural fields, are called as Agrobots. Here in this module we have\u00a0 designed a robot, which can be controlled by using a remote for spraying the pesticides in the field or greenhouse. By the development of these agrobots lot of manual labor will also be decreased. Here in this project a remote is designed with the help of RF transmitter, which encodes the data to the robot for controlling the movement as well as spraying the pesticide. The robot is equipped with RF receiver, which decodes and controls it. The transmitting and receiving modules are constructed using micro-controllers.\r\n\r\nIntroduction to project\r\n\r\n \tThe project aims on the design, development and fabrication of the demonstration unit of the project \u201cPEST CONTROLLING IN AGRICULTURE BY ROBOT.\u201d\r\n \tMore than 42% of the total population in the world has chosen agriculture as their primary occupation. In recent years, the development of autonomous vehicles in agriculture has experienced increased interest. This development has led many researches to start developing more rational and adaptable vehicles. In the field of agriculture autonomous vehicle, a concept is being developed to investigate if multiple small autonomous vehicles, machines would be more efficient than traditional large tractors and human force.\r\n \tThese vehicles should be capable of working 24 hours a day all year round, in most weather conditions. Moreover such a system may have less environmental impact if it can reduce over application of chemicals and high usage of energy, such as diesel and fertilizer, by control that is better matched to stochastic requirements.\r\n\r\nWorking of pest controlling\r\n\r\n \tPest controlling is required in any agriculture field, otherwise it can damage the crops of the fields.\r\n \tPest controlling is either done manually or recently robot by means of liquid pesticides spraying on the crops. It helpful to protect the crops and leaves from insects and fungies.\r\n \tIn most of area it is done manually, but with improvement in technologies about agriculture instruments like robots is used for many works like harvesting of the crops, spraying water to crops, cutting of crops and also providing pesticides to the crops.\r\n \tMany inventers worked on the robots for spraying pesticides and they also gets success, such robots which are helpful to farmers for spraying pesticides called Agrobots.\r\n\r\npest controlling robot\r\n\r\nList of parts of Agrobot\r\n4.1 Components\r\n4.1.1 Keyboard\r\n4.1.2 Microcontroller\r\n4.1.3 Power supply\/Battery\r\n4.1.4 D.C Motors\r\n4.1.5 Air compressor\r\n4.1.6 Air tank and liquid fill tank\r\n4.2 Wheel and carrier\r\n4.2.1 Two wheeled robot\r\n4.3 Sprayer\r\n4.4 Nozzle\r\n\r\nActual model of project\r\nThis project is divided into two modules i.e., the transmitter and the receiver (Agrobot). The transmitter i.e., the remote has been equipped with Keyboard and RF transmitter, which have been interfaced using microcontroller 89C2051. There are 4 keys for controlling the robot. 4 keys are used for the direction control i.e., moving forward, backward, right turn and left turn.\r\n\r\nAdvantages\r\n\r\n \tAvoid the farmer being exposed to toxic pesticide vapors produced during spraying.\r\n \tReduce the workload on the farmer and as it is easier to operate.\r\n \tThe farmer need not spry in the hot sun, he can operate the device while standing in a cooler place.\r\n \tBy the development of these agrobots lot of manual labor will also be decreased and the farmer life will save from chemicals.\r\n \tIt is east to operate and compact in design.\r\n \tIt is inexpensive.\r\n\r\nDownload report :\r\n\r\npages : 50\r\n\r\nClick here to Download Pest controlling agricultural Robot pdf Download\u00a0","headline":"Pest Controlling in agricultural farm using Robot Mechanical Project","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-03-09","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/03\/pest-controlling-robot-210x300.jpg","height":300,"width":210},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/seminar-on-agricultural-robots-report-pdf-free-download/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/03/agricutural-robot-300x192.jpg')"></div><span class="sr-only">link to Seminar on Agricultural Robots Report Pdf Free Download</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/seminar-on-agricultural-robots-report-pdf-free-download/">Seminar on Agricultural Robots Report Pdf Free Download</a></p></header><div class="excerpt"><p>Seminar on Agricultural Robots Report Pdf Free Download

In automatic mode, a fully charged Robo-mower can typically mow a lawn of 2500 to 3200 sq. ft., depending on the number of obstacles in its path, slopes, height of grass, humidity, etc.\r\n\r\n\r\n\r\nFruit picking robot:\r\nFruit picking robot The fruit picking robots are used to pick ripe fruit without damaging the branches or leaves of the tree. The robot can distinguish between fruit and leaves by using video image capturing. The camera is mounted on the robot arm, and the colours detected are compared with properties stored in memory.\r\n\r\n\r\n\r\nMicro flying Robot:\r\nMicro flying Robot Scientists from around the world are reverse-engineering the mechanics of insects as they design midget robots to scout battlefields, search for victims trapped in rubble,and record images in agricultural fields.\r\n\r\n\r\n\r\nAdvantages:\r\nAdvantages Time and manual power is reduced. Fewer errors and at higher speeds. used in various fields like agriculture, medicine, mining, and space research. It can be sent to another planet to study their environmental conditions. The machines could easily work around trees, rocks, ponds and other obstacles.\r\n\r\n\r\nConclusions:\r\n\r\nThe robot-enhanced productivity is very high in agriculture immense and the robots are appearing on farms in various guises.\u00a0The other problems associated with autonomous farm equipment are addressed with this technology. Crop production may be done better and cheaper with small machines than the larger ones. The non-farm community highly accepts the smaller machines. The jobs in agriculture includes highly repetitive decisions hence the robots can exactly substitutes human operators. The quality of the products can be highly sensed and verified by machines accurately.\u00a0 The quality of our lives can be improved by robots by farming many qualitative crops but this process has its own drawbacks.\r\n\r\nDownload Report :\r\n\r\nSeminar on Agricultural Robots Report Pdf Free Download","headline":"Seminar on Agricultural Robots Report Pdf Free Download","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-03-09","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/03\/agricutural-robot-300x192.jpg","height":192,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/what-is-vulcanization-of-rubber-how-to-vulcanize-rubber/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/03/VulcanizationProcess-300x225.jpg')"></div><span class="sr-only">link to What is Vulcanization of Rubber &#8211; How to vulcanize rubber</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/what-is-vulcanization-of-rubber-how-to-vulcanize-rubber/">What is Vulcanization of Rubber &#8211; How to vulcanize rubber</a></p></header><div class="excerpt"><p>What is Vulcanization of Rubber - How to vulcanize rubber

Tensile strength is maximum at optimum cure. Beyond this point, the stock is said to be over cured. It gets stiffer and harder but weaker and less extensible.\r\n\r\n Vulcanization Process\r\nTechniques of\u00a0Vulcanization\r\nVulcanisation can be carried out using several techniques.\r\n\r\n \tCompression Moulding\u00a0\u2013 This is the most common method used in the industry. Here the blank is placed in a two piece mould, one part of which is movable and the other stationary. The mould is closed, then heat and pressure are applied so that the material flows to fill the mould. A little excess of the material is used to ensure that the mould is completely filled.\r\n \tTransfer Moulding\u00a0\u2013 This technique is a variation of compression moulding. The blank is placed in a separate chamber called as pot, preheated to a temperature below cure temperature and transferred into the heated mould where cure takes place. Although in this technique, moulds are more expensive, the process takes shorter cure time due to use of higher temperature and there is better heat transfer.\r\n \tInjection Moulding\u00a0\u2013 Injection moulding is used mostly for plastics. However rubber articles can also be moulded using this technique. The polymer is preheated in a cylindrical chamber, a temperature at which it will flow and is then forced into a comparatively cold, closed mould cavity by means of high pressure. A great advantage of the process is the speed with which the articles can be produced in seconds.\r\n\r\nChange in Properties of Rubber after Vulcanization \u2013\r\n\r\n\r\n\r\n\r\nBefore\u00a0Vulcanization\r\nAfter\u00a0Vulcanization\r\n\r\n\r\nLow viscosity\r\nHigh viscosity\r\n\r\n\r\nLow modulus\r\nHigh modulus\r\n\r\n\r\nLow tensile strength\r\nHigh tensile strength\r\n\r\n\r\nLow elongation\r\nHigh elongation\r\n\r\n\r\nLow hardness\r\nHigh hardness\r\n\r\n\r\nHigh compression set\r\nLow compression set\r\n\r\n\r\nHigh solvent swell\r\nLow solvent swell","headline":"What is Vulcanization of Rubber &#8211; How to vulcanize\u00a0rubber","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-03-09","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/03\/VulcanizationProcess-300x225.jpg","height":225,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/brazing-definition-advantages-and-disadvantages/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/03/brazing.jpg')"></div><span class="sr-only">link to Brazing &#8211; Definition , Advantages and Disadvantages</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/brazing-definition-advantages-and-disadvantages/">Brazing &#8211; Definition , Advantages and Disadvantages</a></p></header><div class="excerpt"><p>Brazing - Definition , Advantages and Disadvantages

Induction brazing\r\n\r\n brazing\r\n\r\nAdvantages\u00a0of Brazing\r\n\r\nFollowing are the advantages of brazing:\r\n\r\n(a) Brazing is used to join a large variety of dissimilar metals.\r\n\r\n(b) Properly brazed joints are pressure tight.\r\n\r\n(c) Pieces having great difference in cross-sectional areas can be brazed.\r\n\r\n(d) Thin sheets, pipes and gauges that can\u2019t be joined by welding can be joined by brazing.\r\n\r\n(e) Complex assemblies can be fabricated by this method.\r\n\r\n(f) A brazed component has ability to preserve protective metal coating.\r\n\r\n(g) Brazing can be done on cast and wrought materials.\r\n\r\n(h) Corrosion resistance joints can be produced by this method.\r\n\r\n(j) Brazing preserves metallurgical characteristics of a material better than welding.\r\n\r\n(k) After brazing a component maintains more precision tolerances than welding.\r\n\r\n(l) Brazing processes can be automated for bulk production.\r\n\r\n(m) Non-metals can be joined to metals.\r\n\r\nDisadvantages\u00a0of Brazing\r\n\r\nFollowing are the disadvantages of brazing:\r\n\r\n(a) It requires tightly mating parts.\r\n\r\n(b) It requires proper cleaning.\r\n\r\n(c) Size of the job is limited.\r\n\r\n(d) Joints are not successful at elevated temperatures.\r\n\r\n(e) Colour of the filler metal may not match with that of the base metal.","headline":"Brazing &#8211; Definition , Advantages and Disadvantages","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-03-09","mainEntityOfPage":"False","dateModified":"February 22, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/03\/brazing.jpg","height":268,"width":245},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <nav class="pagination-wrapper" aria-label="article pagination"> <a class="prev page-numbers" href="?page_num=118">&laquo; PREV</a> <a class="page-numbers" href="?page_num=1"><span class="screen-reader-text">Page </span>1</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=117"><span class="screen-reader-text">Page </span>117</a> <a class="page-numbers" href="?page_num=118"><span class="screen-reader-text">Page </span>118</a> <span aria-current="page" class="page-numbers current"><span class="screen-reader-text">Page </span>119</span> <a class="page-numbers" href="?page_num=120"><span class="screen-reader-text">Page </span>120</a> <a class="page-numbers" href="?page_num=121"><span class="screen-reader-text">Page </span>121</a> <span class="page-numbers dots">&hellip;</span> <a class="page-numbers" href="?page_num=338"><span class="screen-reader-text">Page </span>338</a> <a class="next page-numbers" href="?page_num=120">NEXT &raquo;</a></nav></section></main><aside id="secondary" class="widget-area"><div class="about-wrapper"><h2 class="widget-title" style="background: #d693c6; color: #ff392e">About Us</h2><div class="about-image" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2020/03/Sachin-Thorat-300x300-min.png')"></div><p class="about-copy">LearnMech.Com is a Mechanical Project-oriented platform run by Sachin Thorat who is a B-Tech Graduate in Mechanical Engineering.
