The article discusses the vulnerability of African Catholicism in the face of Pentecostalism, highlighting the Pentecostal explosion in Africa and the proliferation of churches in Kenya and other African countries. It is mentioned that many followers of these churches are Catholics, and the negative reaction of the Catholic Church to this phenomenon is questioned. The concept of the "prosperity gospel" is also addressed, and examples of African churches that promote this idea are mentioned. The text talks about the theology of prosperity in the African context and its appeal to people, as well as the enchanted worldview present in many African churches. [Extracted from the article]

In this article we position ourselves from critical feminist epistemologies which build genealogies from experiences and "multiple and contradictory anchors" (Ciriza 2015 83) to enrich the understanding of the Chile Woke Up Movement. The general characterizations of this phenomenon so far have left open space to place the role of the actions of women and sexual dissidences as an immediate antecedent of the social outbreak (Coordinadora Feminista 8 de Marzo 2021). Our proposal is the special consideration of the political explosions of women and sexual dissidences as part of the fundamental milestones for the understanding of this recent historical process. The interventions analyzed were carried out by the Yeguada Latinoamericana de Cheril Linett, the LasTesis collective, the 8M Feminist Coordinator of Santiago and the Valparaíso Feminist Block, between October 2019 and October 2020.

This study shows the results obtained by PetroBlast S.A.S. Company during the damage control vibrations generated by underground blasting in tunnels and adjacent galleries as part of case studies. The research studies in more details the knowledge of principle of vibrations caused by explosions and its effect on the contour of underground structures, using numerical simulations through software applied to the registered seismic signals. We conclude that vibration velocities and dynamic stresses have an effect on different positions of the tunnel lining, considering that the maximum particle velocity (VPM) directly influences the inland of covering and maximum stresses decrease with rising from the surrounding rock. The VPM recommended safety threshold is 100 mm/s for intact coating. However, in coatings with some type of cracking, the recommended safety thresholds will be around 25 mm/s and 50 mm/s of VMP. These results provide important experiences for future research where seismic control is necessary in underground excavations considering that Colombia is a country located in the northern part of the South American Andes, it is essential to make road tunnels to access to most of the country.

In this article, the author seeks to open discussions regarding the role of the government of Violeta Barrios de Chamorro (1990-1997) in dealing with the legacy of violence in the Sandinista revolution in order to continue generating explanations about the systematic nature of political violence in the country and its weight in democratization until the civil explosion of 2018. For this, various "skillful speeches" of the Chamorro government are analyzed through which a "framed" institutional memory was established. Concluding with the proposal of "dimensioning" violence, making note of various tasks to democratize Nicaraguan memory. [ABSTRACT FROM AUTHOR]

Injuries from explosive devices and the sequelae caused by them have become the focus of various studies in the medical and psychological fields, although in the neuropsychological environment there are few findings, due to this the present investigation arises in order to describe the neuropsychological profile of a group of Colombian soldiers injured by explosive devices. Sixty wounded Colombian soldiers participated and a descriptive analysis of the neuropsychological functions was carried out from the Neuropsi Attention and Memory battery. The participants had a mild to moderate deficit in the coding and recall memory curve; Spontaneous verbal memory, memory by keys and in logical memory, likewise, in executive processes of behavior organization, planning capacity and behavior inhibition. Similarly, a moderate to severe alteration was found in sustained attention, planning and visual coding. The results are discussed with the existing literature. [ABSTRACT FROM AUTHOR]

The serious consequences of the accidents that have occurred in industrial or service installations in recent years (leaks of toxic or flammable substances, fires, and explosions) have established that people, material and environment close to the vicinity of an establishment where hazardous substances are used, processed, transported or stored are subject to greater risks of accidents. The most important aspect is to decide what type and level of risk one is willing to accept in exchange for the economic and social benefits that these facilities represent, for which it is first necessary to identify and evaluate the risks that these facilities represent for the vulnerable elements located in their interior and exterior environment, and based on this, to define the preventive and mitigation protection (safety) measures that must be implemented or reinforced so that the risk levels correspond to those accepted by society. The objective of this work is to describe the main characteristics and limitations of the most commonly used predictive study methods in any of the life stages of the installation under study: design, construction, modification, or operation. It is recommended to use in risk studies the qualitative HAZOP method in processes of any level of complexity, the quantitative ACAF method for complex processes, and the Bow-Tie method when the analysis is focused on determining the efficiency and inadequacy of the control barriers. At the same time, the need for the multidisciplinary team performing the risk assessment to include people with knowledge of both the study methods to be used and the processes to be studied is emphasized.

In this second part of the series of reflections on the photojournalistic image via an analysis of the cover of the Jornal do Povo paper of March 19, 1954, we are interested in understanding thefire and explosions of Maria Celeste beyond the pretended objectivity of its verb-visual-spatial translation. How do the photojournalistic narratives contribute (or can it contribute) to the construction of the memory of the narrated facts? As a result of a critical, reflective, and analytical documentary exercise, and from the bibliographical review of Christoph Wulf 's thought, we believe that this rite is a kind of link between imagination and memory when we see the faces of six dead in the tragedy on that cover.

The article discusses Concern for Lebanon, which includes a series of explosions in the port of Beirut, leaving more than 200 dead and thousands of injured, in addition to damaging hundreds of buildings. The news not only shocked the world by its images and magnitude, also put on the table the social crisis that this country is living, and the precarious conditions work and housing where they are many of its inhabitants.

Coal dust is highly explosive and caused dozens of victims in Colombia. In this research the most important and direct influence on coal dust, especially those that cause combustion and explosion inside the mine factors were analyzed; is important to discuss the characteristics of each coal mined and processed, for actions that do not compromise the integrity of the staff or facilities. Four (4) channel samples of coal exploitation faces with High Volatile Bituminous C from Cerrejón Formation were collected and analyzed: Proximal (moisture, ash, volatile matter, fixed carbon, total sulfur and calorific value ); petrographic (maceral counting and vitrinite reflectance) and Hardgrove mill index. The samples were crushed to obtain fractions corresponding to meshes 200, 270 and 325 considering those sizes could give greater risks of explosion. The analysis showed that there is a direct relationship between the results of the Hardgrove mill index and the degree of explosiveness in the fraction corresponding to 200 mesh, meaning that a higher rate of milling the greater the degree of explosiveness; a direct relationship between calorific inertinite content range and also observed. The 325 mesh fraction for all samples showed the same degree of explosiveness, which indicates that the grain size and the type of coal maceral not influence the content and coal rank. The flash point decreased for finer grains for all samples. Thus, the size of carbon particle is very important as an indicator in the coal-dust explosion factor: finer particles have greater the likelihood of explosion. The percentage of inertinites has a close relationship with the explosivity index, the higher the content of this maceral, coupled with the fine grain, coal dust behaves like a highly explosive element and generate risks in mining operations. Coal rank is an important factor regard to self combustion and explosion of particles with grain sizes greater 200 mesh. If a low rank coal has susceptible and unstable at high temperature elements and this is combined with high volatile matter and some other influential environmental parameters, such as blow air, dust concentration, humidity, and pressure, among others, the ideal combustion and then a likely violent explosion may affect a large portion of mine.

The research aims to identify the variables which influence on the increase of risk for explosions in underground coal mines, especially in the accumulation of coal dust on top of the fortification, as well as analyze how these affect the load losses in the ventilation circuit and the proper evacuation of coal dust. This analysis was carried out by a guide field visits to Nechí Mine (Municipality Amagá, Antioquia) where it was observed that the coal dust accumulated significantly in the wooden doors that in the steel arches, we proceeded to simulate different geometries of fortification and the amount of these for the purpose to determine which is the geometry that contributes to reducing the load losses. After analyzing the different scenarios, the geometry that optimizes the ventilation circuit has been called geometry Circular 2, which shows reduction in load losses of up to 14.67% compared to other geometries analyzed under the same conditions. Whit this, are proposed alternatives more efficient to optimize the ventilation circuit and ensure health and safety conditions for workers inside the mine. [ABSTRACT FROM AUTHOR]

On July 22, 2011, Europe was shook by a tragedy waking it up from its liberal-democratic daydream. Reinhard Heydrich exploded a bomb in Oslo and caused a shootout on Utoya island. What are the implications of these incidents? Social well-being is perhaps not a deterrent to such extreme political expressions. [ABSTRACT FROM AUTHOR]

In order to establish which factors concern with coal dust explosibility in the underground mines samples of coal dust of different mines in Antioquia, Boyaca y Norte de Santander and of lithotypes associations of several coal seams of mine from Antioquia were collected. Samples were under explosibility test, proximate analysis, sizing, petrographic, ignition point, and index of grinding hardgrove (IGH) to the coal seams samples. The results indicate that the majority of coal dust present in the mines is explosive and for this reason it requires of inertization in percentages greater than 60%, with limestone (principally). It was determined that petrographic composition plays a roll preponderant roll in explosibility, i.e., the plies richest in liptinitic components have major explosibility than those rich in vitrinites. The coals with plastic proprieties, due they have free hydrocarbons and produce normally dust very thin, present high indexes of explosibility [ABSTRACT FROM AUTHOR]

To calculate the power of conventional or chemical explosives, several methods and formulae available in both the regulations in place and specialized bibliography were analyzed. Given the limitations of the available procedures that do not provide uniform evaluation criteria and that are markedly based on empiricism to deal with the topic appropriately, new formulae were deduced for the calculation of this key parameter taking as a key element the expression for calculating the power generated by elongated cylindrical charges; which are the most widely used in explosions and the methods to express them are then proposed. The formulae are deduced as a theoretical application to calculate the explosive strength and the detonation pressure of this type of charges. [ABSTRACT FROM AUTHOR]

In the laboured of the quarry of arid The Cacao is faced a problem in the primary explosions, obtaining of a high percentage of pieces with superior dimensions to those admitted by the subsequent links of the technological chain, it causes the necessity of the secondary fragmentation, which brings about numerous inconveniences and the rise in the price of all the works and the increase of the production cost. For a rational design of the explosions is required to know the physical properties of rocks as well as the action of the explosion in the medium. In this work are specified the results of the study of the action of the explosion in the medium caused by the detonation of a compact load of explosive substance. [ABSTRACT FROM AUTHOR]

The advances achieved in the physics of the explosion and the fragmentation of rocks and in general in the mining sciences do not yet allow us to model the process of outburst of the rocks theoretically with precision. The designs of the explosions and of the strains to excavate in underground works are being based fundamentally on the productive experience and the generalization of the obtained results. The values of the criteria of effectiveness that have been reached with these designs are insufficient, that makes it necessary to apply more effective methods to resolve this problem. The investigation carried out is based on the conception of modelling the process of outburst of the rocks theoretically for the excavation of underground works and by means of experimental explosions, carry out the pertinent corrections, discover the regularities that govern the mechanisms of breakdown of the rocks in the strains of wedge and to establish the empiric formulas or semi empirics for the design of the said model.
