There is a growing demand for rapid analytical systems for detecting the presence of humans who are either entrapped as a result of a disaster or in particular hidden, as in the case of smuggling or trafficking. The trafficking and smuggling of people to Europe have reached epidemic proportions in recent years. This does not only put a major strain on European resources, but puts at risk the health and lives of the people being trafficked or smuggled. In this context, the early detection and interception of smuggled/trafficked people is of particular importance in terms of saving migrants from life-threatening situations...

Lei Zhan, Li J Yang, Yu Huang, Qing He, Guan J Liu
BACKGROUND: Out-of-hospital cardiac arrest (OHCA) is a major cause of death worldwide. Cardiac arrest can be subdivided into asphyxial and non asphyxial etiologies. An asphyxia arrest is caused by lack of oxygen in the blood and occurs in drowning and choking victims and in other circumstances. A non asphyxial arrest is usually a loss of functioning cardiac electrical activity. Cardiopulmonary resuscitation (CPR) is a well-established treatment for cardiac arrest. Conventional CPR includes both chest compressions and 'rescue breathing' such as mouth-to-mouth breathing...

Zhuorui Yang, Aura Ganz
In this paper, we introduce a vision-based localization algorithm that can accurately track responders during rescue operations in urban areas that are Global Navigation Satellite System (GNSS)-denied. The proposed algorithm works successfully with the rich visual features of an urban environment and obtains an average localization accuracy of 2.5 ft. In addition, we also provide a 3D representation of the disaster field which reflects the current conditions of the site.

Targets located at the same distance are easily neglected in most through-wall multiple targets detecting applications which use the single-input single-output (SISO) ultra-wideband (UWB) radar system. In this paper, a novel multiple targets vital signs tracking algorithm for through-wall detection using SISO UWB radar has been proposed. Taking advantage of the high-resolution decomposition of the Variational Mode Decomposition (VMD) based algorithm, the respiration signals of different targets can be decomposed into different sub-signals, and then, we can track the time-varying respiration signals accurately when human targets located in the same distance...

Following a mass disaster, it is important that victims are rapidly located as the chances of survival decrease greatly after approximately 48 h. Urban search and rescue (USAR) teams may use a range of tools to assist their efforts but detector dogs still remain one of the most effective search tools to locate victims of mass disasters. USAR teams can choose to deploy human scent dogs (trained to locate living victims) or human remains detection (HRD) dogs (trained to locate deceased victims). However, little is known about the variation between live human scent and postmortem human remains scent and the timeframe during which one type of scent transitions to the other...

Standard operating procedures have been developed to train Cricetomys to locate humans in collapsed structures and return to the release point on command. The present study demonstrated that the schedule of reinforcement for target location influences the rats' performance. Rats required more time to locate targets when no reinforcement was arranged for target location but less time to return to the release point. These findings suggest that training conditions should be based on the priority assigned to target location and return in an operational scenario...

The challenges of achieving successful inter-agency logistic coordination in preparing for and responding to natural disasters and complex emergencies are both well understood and well documented. However, although many of these challenges remain unresolved, the literature reveals that the organisations that form the urban search and rescue (USAR) community have attained a high level of coherence and interoperability that results in a highly efficient and effective response. Therefore, this paper uses the idea of 'borrowing' from other fields as it explores how the processes and procedures used by the USAR community might be applied to improve humanitarian logistic operations...

Urbanization at Tell Brak began in the late 5th millennium BCE and the site reached its maximum size in the Late Chalcolithic (LC) 3, ca. 3900-3600 BCE. During that time, a large midden was formed at the edge of the early city, now known as Tell Majnuna. Rescue excavations at Tell Majnuna revealed several clusters of commingled human remains and a cemetery on the top. Several human skeletons dated to the LC 3 and Early Bronze Age (EBA) were found also at Tell Brak itself and it was possible to investigate differences in cross-sectional femoral and tibial shaft shapes between LC 3 and EBA to test the hypothesis that rapid and extensive urbanization in the LC 3 induced increase in mobility...

OBJECTIVE: Accurate medical evaluation of victims injured during confined space rescues poses significant operational, medical, and logistical challenges for medical providers of all disciplines and experience levels. The Federal Emergency Management Agency (FEMA) teaches rescuers to begin their assessment as soon as verbal contact is obtained with the victim. While a significant amount of information can be obtained by talking to the victim, an accurate assessment of the victim's condition is often limited or impossible...

Gas chromatography with mass spectrometric detection (GC-MS) coupled with solid phase micro-extraction as pre-concentration method (SPME) was applied to identify and quantify volatile organic compounds (VOCs) emitted by human skin. A total of 64 C4-C10 compounds were quantified in skin emanation of 31 healthy volunteers. Amongst them aldehydes and hydrocarbons were the predominant chemical families with eighteen and seventeen species, respectively. Apart from these, there were eight ketones, six heterocyclic compounds, six terpenes, four esters, two alcohols, two volatile sulphur compounds, and one nitrile...

Semi-autonomous control schemes can address the limitations of both teleoperation and fully autonomous robotic control of rescue robots in disaster environments by allowing a human operator to cooperate and share such tasks with a rescue robot as navigation, exploration, and victim identification. In this paper, we present a unique hierarchical reinforcement learning-based semi-autonomous control architecture for rescue robots operating in cluttered and unknown urban search and rescue (USAR) environments. The aim of the controller is to enable a rescue robot to continuously learn from its own experiences in an environment in order to improve its overall performance in exploration of unknown disaster scenes...

The design, development, and validation of a dynamic vapor generator are presented. The generator simulates human scent (odor) emissions from trapped victims in the voids of collapsed buildings. The validation of the device was carried out using a reference detector: a quadrupole mass spectrometer equipped with a pulsed sampling (PS-MS) system. A series of experiments were conducted for evaluating the simulator's performance, defining types and weights of different factors, and proposing further optimization of the device...

Selective reagent ionization time-of-flight mass spectrometry with NO(+) as the reagent ion (SRI-TOF-MS (NO(+))) was applied for near real-time monitoring of selected skin-borne constituents which are potential markers of human presence. The experimental protocol involved a group of 10 healthy volunteers enclosed in a body plethysmography chamber mimicking the entrapment environment. A total of 12 preselected omnipresent in human scent volatiles were quantitatively monitored. Among them there were six aldehydes (n-propanal, n-hexanal, n-heptanal, n-octanal, n-nonanal, and 2 methyl 2-propenal), four ketones (acetone, 2-butanone, 3-buten-2-one, and 6-methyl-5-hepten-2-one), one hydrocarbon (2-methyl 2-pentene), and one terpene (DL-limonene)...

OBJECTIVE: A variety of hazards can precipitate the full or partial collapse of occupied structures. The rescue of entrapped survivors in these situations can be complex, require a multidisciplinary approach, and last for many hours. METHODS: The modern discipline of Urban Search and Rescue, which includes an active medical component, has evolved to address such situations. This case series spans several decades of experience and highlights the medical principles in the response to collapsed structure incidents...
