Lazaro Cardenas

In this project, a prototype was made that is very useful in the industry of the Lazaro Cardenas region, specifically in the area of safety, both in the preparation of fertilization and in mining, given that it arises from the direct need of the worker to exposing themselves to places where pollution levels are high, and are not naturally perceptible to human smell, in the case of gases, or visibility and access, in the case of confined spaces, thus making the use of mobile robots be A viable implementation alternative to avoid puts human life at risk. By means of an ARDUINO MEGA microcontroller and six pairs of servo motors model SG90 embedded in what corresponds to the joints of the legs of the hexapod spider robot, with the appropriate programming the movement of this robot is carried out and with the help of sensors gas, temperature and humidity will be possible to prevent a large number of accidents, by detecting the presence of a gas harmful to health or a temperature at which it is impossible to work and even survive in this area. The LabVIEW program was used to program the interface of the sensors that detected any anomaly present in the environment, and thus a record of any risk can be kept.

AbstractCOVID-19 has impacted human life globally and threatens to overwhelm health-care resources. Infection rates are rapidly rising almost everywhere, and new approaches are required to both prevent transmission, but to also monitor and rescue infected and at-risk patients from severe complications. Point-of-care lung ultrasound has received intense attention as a cost-effective technology that can aid early diagnosis, triage, and longitudinal follow-up of lung health. Detecting pleural abnormalities in previously healthy lungs reveal the beginning of lung inflammation eventually requiring mechanical ventilation with sensitivities superior to chest radiographs or oxygen saturation monitoring. Using a paradigm first developed for space-medicine known as Remotely Telementored Self-Performed Ultrasound (RTSPUS), motivated patients with portable smartphone support ultrasound probes can be guided completely remotely by a remote lung imaging expert to longitudinally follow the health of their own lungs. Ultrasound probes can be couriered or even delivered by drone and can be easily sterilized or dedicated to one or a commonly exposed cohort of individuals. Using medical outreach supported by remote vital signs monitoring and lung ultrasound health surveillance would allow clinicians to follow and virtually lay hands upon many at-risk paucisymptomatic patients. Our initial experiences with such patients are presented, and we believe present a paradigm for an evolution in rich home-monitoring of the many patients expected to become infected and who threaten to overwhelm resources if they must all be assessed in person by at-risk care providers.

AbstractDue to the special sensitivity of typical ecologically fragile areas, a series of human life, mining, and other activities have a greater impact on the environment. In this study, three coal mines in Ordos City on the Loess Plateau were selected as the study area, and the pollution levels of heavy metals in the area were studied by measuring As, Hg, Cr, Cd, Cu, Ni, and Pb in the soil of 131 sampling points. Combined with the concept of “co-occurrence network” in biology, the level of heavy metals in soil was studied using geostatistics and remote sensing databases. The results showed that the concentrations of Hg, Cr, Ni, Cu, and Pb in more than half of the sampling points were higher than the local environmental background value, but did not exceed the risk control value specified by China, indicating that human factors have a greater influence, while Cd and As elements are mainly affected Soil parent material and human factors influence. Heavy metal elements have nothing to do with clay and silt but have an obvious correlation with gravel. Cd, Pb, As and Ni, Cd, Cr are all positively correlated, and different heavy metals are in space The distribution also reflects the autocorrelation, mainly concentrated in the northeast of the TS mining area and the middle of the PS mining area.

The sanctity of human life is the core issue in almost all religions of the world. In the present world scenario, human beings are suffering a lot. Human life is at risk. The most important and precious figure in society is human beings as it is the greatest creature of Almighty Allah. Buddhism and Islam both emphasize the sanctity of human life. The stress laid by the teaching of Islam on the sanctity and respect of human life can be understood by the fact that Islam does not allow the killing of people who are not physically involved in the war. Islam also against suicide. Similarly, the teaching of Buddha has emphasized the holiness and sanctity of human life. According to the philosophy of non-violence in Buddhism (Ahimsa), Killing of human beings is far from Buddhist’s creed even they are against the killing of insects. In Buddhism, “The nonviolence is one of the five precepts of Dhamma, which form the right action, right views and right-thinking on Eightfold Path. This article focuses on the teaching of Buddhism and Islam, a comparative study regarding killing and suicide as these topics are closely related to the sanctity of human life.

Tunnel fires are one of the most dangerous catastrophic events that endanger human life. They cause damage to infrastructure because of the limited space in the tunnel, lack of escape facilities, and difficulty that intervention forces have in reaching the fire position, especially in highly crowded areas, such as Makkah in the Hajj season. Unfortunately, performing experimental tests on tunnel fire safety is particularly challenging because of the prohibitive cost, limited possibilities, and losses that these tests can cause. Therefore, large-scale modeling, using fire dynamic simulation, is one of the best techniques used to limit these costs and losses. In the present work, a fire scenario in the Makkah’s King Abdulaziz Road tunnel was analyzed using the Fire Dynamics Simulator (FDS). The effects of the heat released per unit area, soot yield, and CO yield on the gas temperature, radiation, concentrations of the oxygen and combustion products CO and CO2, and air velocity were examined. The results showed that the radiation increased with the heat released per unit area and the soot yield affected all parameters, except the oxygen concentration and air velocity. The CO yield significantly affects CO concentration, and its influence on the other studied parameters is negligible. Moreover, based on the validation part, the results proved that FDS have limitations in tunnel fires, which impact the smoke layer calculation at the upstream zone of the fire. Therefore, the users or researchers should carefully be concerned about these weaknesses when using FDS to simulate tunnel fires. Further comprehensive research is crucial, as tunnel fires have severe impacts on various aspects of people’s lives.

This paper describes navigation systems for autonomous mobile robots taking part in the real-world Tsukuba Challenge 2013 robot competition. Tsukuba Challenge 2013 enables any information on the route to be collected beforehand and used on the day of the challenge. At the same time, however, autonomous mobile robots should function appropriately in daily human life even in areas where they have never been before. System thus need not capture pre-driving details. We analyzed traverses in complex urban areas without prior environmental information using light detection and ranging (LIDAR). We also determined robot status, such as its position and orientation using the gauss maps derived from LIDAR without gyro sensors. Dead reckoning was combined with wheel odometry and orientation from above. We corrected 2D robot poses by matching electronics maps from the Web. Because drift inevitably causes errors, slippage and failure, etc., our robot also traced waypoints derived beforehand from the same electronics map, so localization is consistent even if we do not drive through an area ahead of time. Trajectory candidates are generated along global planning routes based on these waypoints and an optimal trajectory is selected. Tsukuba Challenge 2013 required that robots find specified human targets indicated by features released on the Web. To find the target correctly without driving in Tsukuba beforehand, we searched for point cloud clusters similar to specified human targets based on predefined features. These point clouds were then projected on the camera image at the time, and we extracted points of interest such as SURF to apply fast appearance-based mapping (FAB-MAP). This enabled us to find specified targets highly accurately. To demonstrate the feasibility of our system, experiments were conducted over our university route and over that in the Tsukuba Challenge.

Abstract. In the past two decades, episodes of flooding on the coast of Alicante (Spain) have led to substantial losses in human life in economic terms. With increased exposure to these phenomena comes also increased vulnerability. Given the various effects of flooding in areas of similar exposure, differences in vulnerability across regions at risk need to be analysed also in terms of the socioeconomic factors of the groups of society that may be affected, and of their perception of risk. This paper studies the increased risk of flooding in three locations on the Alicante coast as a result of urban occupation of areas subject to this hazard. The consequences of the most recent episodes in this area are analysed and a risk assessment, using survey-based research in the affected areas, is performed.

Accumulation Mechanism

It is known that particle accumulation is beneficial for dust removal in industry. In order to understand better particle accumulation mechanism, experiments were carried out to analyze the influence of flue gas temperature and humidity on ash accumulation. It is found that the Engineering Acid Dew Temperature (EADT) of flue gas is an important parameter that determines the efficiency of particle accumulation. When the gas temperature is lower than the EADT, the sulfuric acid in the flue gas and ash humidity rise dramatically, which leads to particle accumulation. In order to improve the collection efficiency, the flue gas temperature can be controlled to trigger particle accumulation.
