The leakage of hazardous gases and chemical vapors is considered one of the dangerous accidents that can occur in laboratories, workshops, warehouses, and industrial sites that use or store these substances. The early detection and alarming of hazardous gases and volatile chemicals are significant to keep the safety conditions for the people and life forms who are work in and live around these places. In this paper, we investigate the available mobile detection and alarming systems for toxic, hazardous gases and volatile chemicals, especially in the laboratory environment. We included papers from January 2010 to August 2021 which may have the newest used sensors technologies and system components. We identified (236) papers from Clarivate Web of Science (WoS), IEEE, ACM Library, Scopus, and PubMed. Paper selection has been done based on a fast screening of the title and abstract, then a full-text reading was applied to filter the selected papers that resulted in (42) eligible papers. The main goal of this work is to discuss the available mobile hazardous gas detection and alarming systems based on several technical details such as the used gas detection technology (simple element, integrated, smart, etc.), sensor manufacturing technology (catalytic bead, MEMS, MOX, etc.) the sensor specifications (warm-up time, lifetime, response time, precision, etc.), processor type (microprocessor, microcontroller, PLC, etc.), and type of the used communication technology (Bluetooth/BLE, Wi-Fi/RF, ZigBee/XBee, LoRa, etc.). In this review, attention will be focused on the improvement of the detection and alarming system of hazardous gases with the latest invention in sensors, processors, communication, and battery technologies.

Pro-Life or Pro-Choice? Humanistic Buddhists’ Voices Surrounding Abortion in Contemporary Taiwan

In Taiwan, abortion was legalized in 1984. This paper examines the voices surrounding abortion expressed by monasteries in Humanistic Buddhism, a prominent Buddhist philosophy practiced in modern Taiwan. Humanistic Buddhism emphasizes that it is a “religion of the people.” However, in addition to the law of karma and causality, the value of all life forms is prioritized based on the ethics of “non-harming (ahimsā).” When some monasteries insist that abortion is killing, resulting in karmic retribution, some express sympathy with a woman’s decision to abort. When some monasteries promote a newly popularized ritual to appease aborted fetuses, some are keenly critical of the exploitation of women and manipulation of scriptures. Through a discursive analysis, this paper demonstrates the wide spectrum of Buddhist narratives in response to reproductive politics embedded in the conflicts between modernity and tradition, as well as locality and globality.

In the early days of the petroleum industry, oil infrastructure had a short lifespan. Individuals were creating their own company and competing with others, without the financial means of current great companies. Many oil facilities were established in port cities like Dunkirk, because they were the entrance gates to many nations. In the case of Dunkirk, many former oil sites became houses and schools in the current urban tissue, and official records lost track of many others. The limited data available on official records to inform the people on the pollution of their soil is a threat to their safety and health, and an obstacle for the planning strategies of public authorities. The analysis of archival documents, past and present aerial pictures, paintings and mapping techniques related to geographic information systems (GIS) can reveal lost industrial sites, and thus indicate potential pollution. This paper investigates the oil history of Dunkirk as a background for its petroleum history and its transferability to other petroleum related cities. A cross analysis of sources will attempt to complete French files and locate oil sites. The objective is to illustrate the transformation of former oil sites, and why the current land use is often not compatible with its history.

Background extinction is a natural phenomenon. Anthropogenic biodiversity loss has been addressed from the various view points. The debate is continuing to identify the root cause of the anthropogenic mass extinction, also called the sixth extinction. The present communication discusses various anthropogenic drivers of the biodiversity loss and explains the ongoing sixth mass extinction using Garrett Hardin's “the tragedy of the commons”. Such explanations provide options for policy makers and for us to save the precious biodiversity of our planet. It has been demonstrated that presently we share about one third of the Net Primary Productivity which must be reduced through reducing our food consumption and by reducing our utilization of energy. Promotion of sustainable human behaviours to ameliorate the problem of anthropogenic extinction or the sixth extinction has been discussed in the light of recent findings from neurobiology and molecular biology. Biodiversity conservation through providing benefit to the people may be effective conservation strategies which would save the interest of human civilizations as well as other life forms on the earth.

The results presented in this paper originate from an EU research project that is near toits completion. The goal was to build a model that can be applied to all industrial sites inthe Mediterranean area. The approach followed to achieve the objectives was to study allthe new technologies and systems that, if applied globally, can make the whole areasustainable both energetically and environmentally. The application of the model allowsthe design and implementation of self-sufficient green areas in terms of energy which alsobrings to the reduction of the emissions into the atmosphere. An aim of the project wasalso to identify possible sources of funding or incentives. The main beneficiaries of theresults are SMEs that through a more responsible approach to the environment could getgreater market competitiveness and reduce energy costs of their enterprises. Otherbeneficiaries are the people who obtain advantages from a clearer and less pollutedsurrounding environment.The paper presents the results obtained from the application of the model in some pilotcases.

Soil Gas Survey

Cities are major contributors to greenhouse gas emissions (GHG) due to the high density of urbanization, numerous industrial centers, and intensive agricultural activities. This study focused on soil methane and radon gas measurements in the subsurface, as well as in the atmosphere. Measurements were conducted using new gas detection instrumentation and as low-cost devices for methane gas concentrations. Maximum soil radon gas concentration was observed to be approximately 1770 ± 582 Bq/m3 at a depth of 1 m below the ground surface. The soil comprised of 64.31% sand, 20.75% silt, and 14.94% clay, and 0.526 ppm of uranium. The maximum concentration of methane was about 0.06%, at a depth of 1 m into the soil, characterized by 83% sand, 8.96% silt, and 7.89% clay. Moreover, this study focused on a better understanding of the advantages and disadvantages of new soil gas detection technology. The results and findings of environmental data obtained from the soil gas survey were shared with the community, whose involvement was critical in the data acquisition process.

Quick, accurate and reliable detection of mash gas plays an important role in the coal industry. This paper presents a novel method to get the infrared absorption peak wavelength by light splitting using plane blazed grating, instead of using filter conventionally. The principle and setup of producing 3.433μm and 4.65μm wavelength lights for detecting CH4 and CO concentration are described in details. The work provides a simple, but efficient option to the infrared absorption gas detection technology.
