Unmanned Vehicle for Gas Leakage Detection Using Raspberry PI

In this day and age, security assumes a key part and it is critical to consolidate compelling wellbeing frameworks in areas for tutoring and work. The new security model sent in enterprises and this system are refreshed by this work. In homes and workplaces, it can likewise be found numerous mishaps have occurred, for example, fire impacts because of gas spillage. On the off chance that the spillage isn't distinguished at a beginning phase, such mishaps can have hurtful outcomes. The essential objective of the work comprises of fostering a poisonous gas discovery and cautioning gadget dependent on microcontrollers. The poisonous gases like LPG and propane whenever detected ought to be shown and advise every single second in the Cloud. In the event that they outperform these gases, At that point we may make a move on it promptly because of cloud perception at the normal level.

Rancang Bangun Mesin Replika Penghasil Gas Vulkanik sebagai Studi Awal Monitoring Erupsi Gunung Berapi

Indonesia is one of the countries that has the third-largest number of volcanoes in the world. Several volcanoes are still active today. This places Indonesia prone to disasters from the volcano. One of the volcanic activities is characterized by the release of poisonous gases such as CO2. At a certain threshold, this poisonous gas can kill living things. This research has designed a gas-producing engine as a replica of volcanic gas. This machine is very supportive of the development of volcanic gas research on a laboratory scale because it has the advantage of being lighter, simpler construction, cheaper and portable machine construction process. The gas produced by the machine is tested using the Dragger X-am 7000. , CO2, H2S, SO2, and CO. The results were obtained for 60 seconds of starting the engine, namely CH4 2.0% LEL, CO2 1.6% Vol, H2S 4.3 ppm, SO2 1.0 ppm, and CO 271 ppm.

The synthesis and bioimaging of a biocompatible hydrogen sulfide fluorescent probe with high sensitivity and selectivity

Hydrogen sulfide (H2S), a well-known poisonous gas, has been recognized as a critical endogenous gas transmitter in the past decade.

Corrosion Analysis of Damage Resistant Materials used in Military Armoured Vehicles in Poisonous Gas Environment

With the improvement of China’s military strength, military armoured vehicles are very effective in dealing with various harsh environments. The poisonous gas environment is very serious against the body of the military armoured vehicle. For this reason, the damage-resistant material for the car needs to be developed, and the corrosion resistance of the material is analysed. Metal and polymer damage resistant materials are selected as research objects. In the three environments of alkaline poison gas, industrial poison gas and acid gas, the outdoor exposure test is carried out, and the indoor accelerated test under the combined environmental factors is implemented to obtain the mechanism of corrosion and aging behaviour of the typical material of the vehicle. Experiments show that the damage resistant material can effectively enhances the corrosion resistance of the car body in a poisonous gas environment.

<p><strong>Abstract:</strong> This article aims to present that sorcery and witchcraft<br />is still widely practiced in Flores. It is one of the main thorny<br />sources of social conflicts in almost every village. There have<br />been a hot-witch hunts at many regions of the islands. Numerous<br />witches or sorcerers caught red-handed practicing it were tried<br />according customary laws of the villagers and then killed publicly.<br />This article also presents that a number of paranormals can prove<br />the existence of the sorcery practices. The mediums used by the<br />perpetrators can be detected. These mediums were claimed to<br />emit a kind of toxic gas which is thought to cause the victim to<br />get sick and die. This poisonous gas will, however, disappear only<br />if it is sprinckled by the sacramental holy water and its victim will<br />slowely recover.</p><p><br /><strong>Keywords:</strong> black magic, sorcery, witchcraft, paranormal, divine<br />power, holy water.</p>

Major General Malcolm C. Grow, M.D. (1887–1960) Soldier, Surgeon, Airman

World War I (WWI) and World War II (WWII) both presented physicians with challenges unseen before in history. New inventions such as the machine gun and poisonous gas in WWI and the massive aircraft battles in WWII required physicians and surgeons to adapt and innovate to provide the best care and preventative measures for service members. One physician, Malcolm Cummings Grow, distinguished himself as an innovator, a researcher, and a leader. His contributions to the field of military medicine, flight surgery, and medical administration led to countless lives being saved during the two World Wars and laid the groundwork for many different combat protective equipment still in use today.

Information as a Policy Tool: The Toxics Release Inventory

The Toxics Release Inventory, created in the aftermath of the Bhopal poisonous gas tragedy in India, is a cornerstone of the environmental right-to-know program in the U.S. TRI is the nation’s first program to use information as an explicit tool of public policy. The program incorporates several novel features, but does not require companies to reduce toxic pollution. However, the “report card” aspect of publicly-available information has spurred substantial reductions nonetheless.
