The project deals with the development of a cooling system for mining helmet using powerful fan technology. The system consists of mainly two fans and batteries. Electrical power is used to run the fan, which creates a temperature difference inside the helmet and facilitates cooling. Fans are used to suck the air from the surrounding and air is circulated inside the helmet and provides a soothing cool breeze inside the helmet. The numerical and experimental results indicate that the temperature inside the helmet can be reduced by 4-5 <sup>0</sup>C in approximately 3-4 minutes in the mining helmet.</p> Hanumesha Pujar Syed Suhel Naveen Dinakar Chetan Baseganni Mayur Gohil Rahul Kulkarni ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 2017-08-14 2017-08-14 3 1 3 8 10.21467/ajgr.3.1.3-8 Ketamine-induced Changes in Blood Pressure and Heart Rate in Pre-hospital Intubated Patients https://journals.aijr.in/index.php/ajgr/article/view/247 <p>When a patient experiences trauma, pre-hospital rapid sequence intubation (RSI) is often the course of action. While RSI is associated with favorable neurological outcomes among traumatic brain injury patients, it also carries the risk of increased hypotension and bradycardia. Ketamine is a fast-acting anesthetic agent used in RSI, attractive due to its ability to raise heart rate (HR) and blood pressure (BP) and thus potentially lessening the severity of RSI-related hypotension and bradycardia. However, research in support of its use is inconclusive, with different studies reporting increases or decreases in BP and HR after ketamine administration. To study the effect of ketamine on HR and BP during RSI, we analyzed the data obtained from 1,516 patients who received trauma and non-trauma medical care including RSI from first responders and emergency personnel using two different statistical methods. We determined if there was any association between the vital signs prior to administration of ketamine and outcomes such as bradycardia and/or hypotension post-ketamine administration in patients undergoing RSI. We found that the vital signs prior to administration of ketamine (i.e. BP and HR) predict the development of bradycardia and/or hypotension in patients undergoing RSI and the relationship between baseline vital signs and the development of bradycardia and/or hypotension is moderated by the dose of ketamine. Results obtained from this study may help responders and emergency care personnel to identify the patients that are likely to benefit from ketamine as an anesthetic agent.</p> Milan Kirit Sheth Asher Brand Julia Halterman ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 2017-10-04 2017-10-04 3 1 20 33 10.21467/ajgr.3.1.20-33 Design and Analysis of Bamboo Stick Cutting Machine https://journals.aijr.in/index.php/ajgr/article/view/241 <p>As the modern trend is approaching more towards handcrafted art and natural artifacts, the demand for such hand-crafted arts has increased tremendously. To meet this increasing market demand there is always a need for advancement in the conventional production techniques so as to counterbalance the ever-increasing market demand for such handcrafted arts. India is known for many cottage industries and handicrafts designs but still, continuous efforts are required to design and produce unique handicrafts to satisfy the customer demands. In most of the large-scale industries, production is achieved with the help of machines but whereas in small-scale production, the man force is a must to carry out the entire production manually which results in the increased workload on workers which ultimately affect production rate as well as quality. To overcome this and to minimize the stress on the worker, an attempt has been made to design a bamboo stick making machine, which is simple in design and even can be handled by unskilled labor. The designed Bamboo cutting machine is mainly used to cut the bamboo into required shapes which are used in small-scale industries to prepare ice cream sticks or incense sticks. Our main concern is to avoid the manual operation of cutting bamboo which is time-consuming. The cutting operation is achieved by using a pair of spur gears and rollers.</p> Chetan Baseganni Syed Suhel Hanumesha Pujar ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 2017-10-04 2017-10-04 3 1 34 40 10.21467/ajgr.3.1.34-40 Density Functional Theory Calculation of Band Gap of Iron (II) disulfide and Tellurium https://journals.aijr.in/index.php/ajgr/article/view/300 <p>In this work, the band gap of Iron(II) disulfide and Tellurium were computed using the density functional theory with different meta-GGA functionals. The results showed that the meta-GGA functional M06L gave the closest value of the band gap as 0.96 eV compared to the experimental value of 0.95 eV for Iron(II) disulfide while the meta-GGA functional BJ06 gave the closest value of the band gap as 0.339 eV compared to the experimental value of &nbsp;&nbsp;&nbsp;&nbsp;0.335 eV for Tellurium. This study showed that the meta-GGA functionals M06L and BJ06 can effectively predict the band gap of Iron(II)disulfide and Tellurium. In general, the use of meta-GGA functionals can be extended to compute the band gap of other semiconductors.</p> Arumona Edward Arumona Amah A N ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 2017-11-18 2017-11-18 3 1 41 46 10.21467/ajgr.3.1.41-46 A Summary of Current Research on the Functional Morphology of Flight in Azhdarchid Pterosaurs https://journals.aijr.in/index.php/ajgr/article/view/224 <p>Azhdarchid pterosaurs existed during the Mesozoic era and died out during the mass extinction at the end of the Cretaceous. These amazingly large creatures have sparked a debate on whether they were capable of flying or simply gliding due to their massive size, anatomy, and morphology. Two theories that have been developed are that these creatures were terrestrial stalkers and that they are closer to pelicans in terms of feeding capability. More specifically, Naish and Witton suggest that these giants were capable of covering large distances by soaring and could forage on land by walking quadrupedally using their long necks to reach down and kill small animals, consume dead tissues and possibly fruits. Fossil evidence to support this theory includes tracks of the Azhdarchid’s showing a parasagittal gait, a winged planform, and specimens have been only found in continental depositional settings. Evidence also indicates that these creatures had membranes serving as wings, but it cannot be discerned with current knowledge whether membranes were used for gliding or for true flying.</p> Amy Klein Curt W Anderson ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 2017-08-14 2017-08-14 3 1 9 12 10.21467/ajgr.3.1.9-12 Amyotrophic Lateral Sclerosis and Oral Health https://journals.aijr.in/index.php/ajgr/article/view/196 <p>Amyotrophic lateral sclerosis (ALS), commonly referred to as Lou Gehrig’s disease is a progressive degenerative disorder that affects the nervous system, particularly the motor neurons. It may affect either spinal or bulbar neurons, which classify how symptoms present in the individual. Currently, the cause of ALS is unknown, although research indicates the possibility of genetic and environmental factors affecting its incidence. It is important for health care practitioners to understand amyotrophic lateral sclerosis to enable them to make modifications to patient care as needed.</p> Aakash Shah Purvesh Shah Santosh Kumar Goje Romil Shah Bhumi Modi ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 2017-08-18 2017-08-18 3 1 13 19 10.21467/ajgr.3.1.13-19
