A civilian perspective on ballistic trauma and gunshot injuries
Philipp Lichte, Reiner Oberbeck, Marcel Binneb?sel, Rene Wildenauer, Hans-Christoph Pape, Philipp Kobbe
Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine , 2010, DOI: 10.1186/1757-7241-18-35
Abstract: A search of the National Library of Medicine and the National Institutes of Health MEDLINE database was performed using PubMed.Craniocerebral gunshot injuries are often lethal, especially after suicide attempts. The treatment of non space consuming haematomas and the indications for invasive pressure measurement are controversial. Civilian gunshot injuries to the torso mostly intend to kill; however for those patients who do not die at the scene and are hemodynamically stable, insertion of a chest tube is usually the only required procedure for the majority of penetrating chest injuries. In penetrating abdominal injuries there is a trend towards non-operative care, provided that the patient is hemodynamically stable. Spinal gunshots can also often be treated without operation. Gunshot injuries of the extremities are rarely life-threatening but can be associated with severe morbidity.With the exception of craniocerebral, bowel, articular, or severe soft tissue injury, the use of antibiotics is controversial and may depend on the surgeon's preference.The treatment strategy for patients with gunshot injuries to the torso mostly depends on the hemodynamic status of the patient. Whereas hemodynamically unstable patients require immediate operative measures like thoracotomy or laparotomy, hemodynamically stable patients might be treated with minor surgical procedures (e.g. chest tube) or even conservatively.In contrast to a stagnating incidence of civilian gunshot wounds in the United States, gunshot violence shows different trends in European countries. Firearm associated crime was increasing up to 30% in the UK between 1998 and 2002 [1]. In the same period firearm associated crime in Germany was markedly decreasing. In 2007 in Germany only 4558 criminal acts with the use of firearms were registered [2]. Additionally, in high income countries a significant number of gunshot wounds are related to suicide attempts [3]. As seen in the United States, gunshot violence has bes
Infectious agents are associated with psychiatric diseases

Abstract: There are several infectious agents in the environment that can cause persistent infections in the host. They usually cause their symptoms shortly after first infection and later persist as silent viruses and bacteria within the body. However, these chronic infections may play an important role in the pathogenesis of schizophrenia and Tourette’s syndrome (TS). We investigated the distribution of different neurotrophic infectious agents in TS, schizophrenia and controls. A total of 93 individuals were included (schizophrenic patients, Tourette patients and controls). We evaluated antibodies against cytomegalovirus (CMV), herpes-simplex virus (HSV), Epstein-Barr virus, Toxoplasma, Mycoplasma and Chlamydia trachomatis/pneumoniae. By comparing schizophrenia and TS, we found a higher prevalence of HSV (P=0.017) and CMV (P=0.017) antibodies in schizophrenic patients. Considering the relationship between schizophrenia, TS and healthy controls, we showed that there are associations for Chlamydia trachomatis (P=0.007), HSV (P=0.027) and CMV (P=0.029). When all measured viruses, bacteria and protozoa were combined, schizophrenic patients had a higher rate of antibodies to infectious agents than TS patients (P=0.049). Tourette and schizophrenic patients show a different vulnerability to infectious agents. Schizophrenic patients were found to have a higher susceptibility to viral infections than individuals with TS. This finding might point to a modification in special immune parameters in these diseases.
Robust Real-Time Tracking for Visual Surveillance
Thirde David,Borg Mark,Aguilera Josep,Wildenauer Horst
EURASIP Journal on Advances in Signal Processing , 2007,
Abstract: This paper describes a real-time multi-camera surveillance system that can be applied to a range of application domains. This integrated system is designed to observe crowded scenes and has mechanisms to improve tracking of objects that are in close proximity. The four component modules described in this paper are (i) motion detection using a layered background model, (ii) object tracking based on local appearance, (iii) hierarchical object recognition, and (iv) fused multisensor object tracking using multiple features and geometric constraints. This integrated approach to complex scene tracking is validated against a number of representative real-world scenarios to show that robust, real-time analysis can be performed.

Hydraulic Reliability Assessment and Optimal Rehabilitation/Upgrading Schedule for Water Distribution Systems  [PDF]
Wei Peng, Rene V. Mayorga
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.718184
Abstract: This paper develops an innovative approach to optimize a long-term rehabilitation and upgrading schedule (RUS) for a water distribution system with considering both hydraulic failure and mechanical performance failure circumstances. The proposed approach assesses hydraulic reliability dynamically and then optimizes the long-term RUS in sequence for a water distribution system. The uncertain hydraulic parameters are treated as random numbers in a stochastic hydraulic reliability assessment. The methodologies used for optimization in a stochastic environment are: Monte Carlo Simulation, EPANET Simulation, Genetic Algorithms, Shamir and Howard’s Exponential Model, Threshold Break Rate Model and Two-Stage Optimization Model. The proposed approach is conducted on a simulation model of water distribution network in a computer by two universal codes, namely the hydraulic reliability code and the optimal RUS code. The applicability of this approach is verified in an example of a benchmark water distribution network.
Collision Vehicle Detection System Based on GPS/INS Integration  [PDF]
Neda Navidi, Rene Jr. Landry
Journal of Computer and Communications (JCC) , 2017, DOI: 10.4236/jcc.2017.52006
Abstract: Continuous vehicle tracking as well as detecting accidents, are significant services that are needed by many industries including insurance and vehicle rental companies. The main goal of this paper is to provide methods to detect the position of car accident. The models consider GPS/INS-based navigation algorithm, calibration of navigational sensors, a de-nosing method as long as vehicle accident, expressed by a set of raw measurements which are obtained from various environmental sensors. In addition, the location-based accident detection model is tested in different scenarios. The results illustrate that under harsh environments with no GPS signal, location of accident can be detected. Also results confirm that calibration of sensors has an important role in position correction algorithm. Finally, the results present that the proposed accident detection algorithm can recognize accidents and related its positions.
Microartrópodos de la estepa altoandina altiplánica, con detalle de especies de oribátidos (Oribatida: Acarina)
Covarrubias, Rene;
Neotropical Entomology , 2009, DOI: 10.1590/S1519-566X2009000400007
Abstract: in soils under seven types of high altitude, native vegetation and one plantation in the northernmost chilean altiplanic region, 20 microarthropod orders or suborders were found, including 21 oribatid mite species. seven of these species are first mentioned for chile. no oribatid mites were found in soils far from vegetation. data are given as average densities (no ind./1000 ml), accounting for plant preference, geographical distribution and updated taxonomic status for each species. ten oribatid species form a group of andean altiplanic steppe fauna also found in peru and bolivia. other three species have been also found in different austral ecosystems in argentina, and a group of eight species seems to be cosmopolitan.
Expertise and Global Water Governance: How to Start Thinking about Power over Water Resources
Uruena, Rene;
Anuario mexicano de derecho internacional , 2009,
Abstract: power over water resources has been mostly spared of critical scrutiny. departing from such trend, this paper explores the background of water politics, and argues the existence a regulatory space called "global water governance" (gwg). gwg is an "area of expertise", wherein "politics" is negatively perceived and expressly rejected. through this move, "expertise" becomes the corner stone to understand governance of water resources. i submit that expertise is not an attribution, but a power relation. as such, it is commonly perceived as undemocratic; hence, the denunciation of "expert rule" is usually followed up by a call for some sort of majoritarian rule. and yet, the specific characteristics of expert power turn futile such call. for this reason, alternative vehicles of resistance are needed; and accountability of experts may be the place to look.
Globalization and occupational health: a perspective from southern Africa
Loewenson,Rene;
Bulletin of the World Health Organization , 2001, DOI: 10.1590/S0042-96862001000900012
Abstract: increased world trade has generally benefited industrialized or strong economies and marginalized those that are weak. this paper examines the impact of globalization on employment trends and occupational health, drawing on examples from southern africa. while the share of world trade to the world's poorest countries has decreased, workers in these countries increasingly find themselves in insecure, poor-quality jobs, sometimes involving technologies which are obsolete or banned in industrialized countries. the occupational illness which results is generally less visible and not adequately recognized as a problem in low-income countries. those outside the workplace can also be affected through, for example, work-related environmental pollution and poor living conditions. in order to reduce the adverse effects of global trade reforms on occupational health, stronger social protection measures must be built into production and trade activities, including improved recognition, prevention, and management of work-related ill-health. furthermore, the success of production and trade systems should be judged on how well they satisfy both economic growth and population health.
Contrapuntos hagiográficos sobre el Venerable Fr. Pedro de Urraca (Jadraque 1583 - Lima 1657)
Millar,Rene;
Teología y vida , 2008, DOI: 10.4067/S0049-34492008000300015
Abstract: this article analyzes four hagiographies-two of them unpublished-that were written in different periods about the venerable friar pedro de urraca, who was born in jadraque, spain, in 1583, and died in lima, renowned for his sanctity, in 1657. the author studies the content and objective of these literary works with the purpose of appreciating the differences and the variations over time that they present and reflect, from the perspective of religious mentality. however, the author also examines the relation they had with the process of beatification of the protagonist, in order to try to understand the influence that they exercised on said process. at the same time, the author attempts to see the way in which this process left its traces on the characteristics and direction of the works. in this context, the author proposes that the first of the hagiographies, written within a month of the death of this servant of god and still unpublished, had a great influence on the direction that the cause of beatification took and, up to a certain point, marked the trajectory of the beatification process. the author also claims that this first hagiography influenced, directly or indirectly, the hagiographies that were written afterwards.
