Hydrogen（H2） is a clean energy carrier with enormous potential to support deep decarbonization towards net-zero and a circular carbon economy. However, H2production itself can be carbon and energy intensive, as 96% of global H2synthesis is currently conducted via thermochemical processes such as steam reforming and coal gasification that rely on fossil fuels [1].

Recent advances in understanding of pancreatitis and advances in technology have uncovered the veils of idiopathic pancreatitis to a point where a thorough history and judicious use of diagnostic techniques elucidate the cause in over 80% of cases. This review examines the multitude of etiologies of what were once labeled idiopathic pancreatitis and provides the current evidence on each. This review begins with a background review of the current epidemiology of idiopathic pancreatitis prior to discussion of various etiologies. Etiologies of medications,infections,toxins,autoimmune disorders,vascular causes,and anatomic and functional causes are explored in detail. We conclude with management of true idiopathic pancreatitis and a summary of the various etiologic agents. Throughout this review,areas of controversies are highlighted.

For decades sections of the academic community have been emphasizing that disasters are not ***, politicians, the media, various international organizations—and, more surprisingly, many established researchers working in disaster studies—are still widely using the expression 'natural disaster.' We systematically analyzed the usage of the expression 'natural disaster' by disaster studies researchers in 589 articles in six key academic journals representative of disaster studies research,and found that authors are using the expression in three principal ways:(1) delineating natural and human-induced hazards;(2) using the expression to leverage popularity;and(3) critiquing the expression 'natural disaster.' We also identified vulnerability themes that illustrate the context of 'natural disaster' usage. The implications of continuing to use this expression, while explicitly researching human vulnerability, are wide-ranging, and we explore what this means for us and our peers. This study particularly aims to stimulate debate within the disaster studies research community and related fields as to whether the term 'natural disaster' is really fit for purpose moving forward.

INTELLIGENT SECURITY SYSTEMS ENGINEERING FOR MODELING FIRE CRITICAL INCIDENTS:TOWARDS SUSTAINABLE SECURITY

An intelligent security systems engineering approach is used to analyze fire and explosive critical incidents, a growing concern in urban communities. A feed-forward back-propagation neural network models the damages arising from these critical incidents. The overall goal is to promote fire safety and sustainable security. The intelligent security systems engineering prediction model uses a fully connected multilayer neural network, and considers a number of factors related to the fire or explosive incident including the type of property affected, the time of day, and the ignition source. The network was trained on a large number of critical incident records reported in Toronto, Canada between 2000 and 2006. Our intelligent security systems engineering approach can help emergency responders by improving cr^tical incident analysis, sustainable security, and fire risk management.

Background: Taxonomic treatment of the Zoothera dauma species complex is highly variable and has been hampered by the absence of song recordings for the Nilgiri Thrush(Zoothera [aurea] neilgherriensis).Methods: I obtained two recordings of the song of neigherriensis from southern Indian. Here I publish sonograms and analyze song recordings for all but one currently described taxon from the Eurasian portion of the geographic range of this species complex. Principal component analyses were used to investigate song differences between ***: The song of neigherriensis is a highly complex series of strophes remarkably similar to the song of the insular Zoothera major. Vocal analyses across the complex indicate four key groups of taxa differentiated in their songs:(1) simple flat whistled songs which include the northern aurea, toratugumi and the undescribed Taiwan population;(2) eastern populations of dauma(reported here for the first time) which sing like northern birds but with much broader bandwidth,(3) strongly down-slurred, thin whistles of tropical resident imbricata of Sri Lanka and horsfieldi of Indonesia, and(4) highly complex songs of Himalayan dauma, neilgherriensis and ***: Zoothera dauma is unlikely to represent a single species given the simple singing populations from its eastern range and highly complex song from the Himalayan portion of its range. neilgherriensis should either be transferred from Zoothera aurea, where it is currently classified as a subspecies, and be placed as a subspecies within Z. dauma from the Himalayas or it should be recognized as a distinct species. Given the small number of songs available for analyses, I suggest the former course until it can be clearly demonstrated that neilgherriensis and Himalayan dauma are vocally distinct.
