Resumen

Introduction: Institute of Aerospace Medicine (IAM) Indian Air Force (IAF) conducts operational training in Aerospace Medicine for IAF fighter aircrew since 2009. This includes high-G training with qualifying criteria of demonstrating ability of the aircrew to sustain 9G for 5 s in closed-loop run (pilot-in-control) wearing anti-G suit while performing anti-G straining maneuver (AGSM). Incidences of inadvertent almost loss of consciousness (A-LOC)/G-induced loss of consciousness (G-LOC) are an unavoidable unintended consequence of such training. The aim of the paper is to study the incidence of G-LOC and A-LOC and its nature in the high-performance human centrifuge (HPHC) and compare it with our previous experiences. Material and Methods: A G-LOC/A-LOC proforma was designed at the Department of Acceleration Physiology and Spatial Orientation at IAM IAF to understand the nature and cause of the G-LOC/A-LOC. This was to be filled up by the aircrew on a voluntary basis. The data were analyzed using Microsoft Excel with a significance level set at 95% confidence interval and alpha ≤0.05. Results: Fifty-two aircrew (19.92%) experienced inadvertent G-LOC/A-LOC in 83 such episodes (54 G-LOC and 29 A-LOC) during the period January 2018–December 2018. Forty-seven aircrew experiencing G-LOC/ALOC agreed to be part of the study and filled up the proforma after the episodes. The incidence of G-LOC in the institute has reduced significantly over the past two decades, perhaps due to change in the HPHC used for training of aircrew. The incidence of G-LOC found in this study is comparable to the global incidence. Rise in heart rate was higher during A-LOC than G-LOC and was found to be statistically significant (t statistic = 2.33; P = 0.01). Relative incapacitation period was lesser than absolute incapacitation period during G-LOC and was found to be statistically significant (t statistic = 3.29, P = 0.001). G-level at which Type II G-LOC occurred was significantly higher than the Type I G-LOC. Conclusion: The incidence of A-LOC/G-LOC has reduced over the past two decades of high G training in IAF and is comparable to global incidence.

Resumen

Introduction: G-induced loss of consciousness (G-LOC) has been extensively investigated and pathophysiology of the same has been well elucidated in the literature. The syndrome of almost loss of consciousness or ALOC has also been described which is a loose collection of signs and symptoms of a physiological, emotional, and cognitive nature. This is believed to occur under +Gz stress which is insufficient to cause G-LOC. Institute of Aerospace Medicine IAF regularly conducts high-G training for its fighter pilots in the High Performance Human Centrifuge. Episodes of G-LOC and ALOC are unintended outcomes of such training. A study was conducted to understand the nature of these episodes in the Department of Acceleration Physiology and Spatial Orientation. Material and Methods: A G-LOC/ALOC proforma was designed in the Department of Acceleration Physiology and Spatial Orientation to understand the nature and causes of the G-LOC/ALOC and was filled up by the aircrew on a voluntary basis. The data were analyzed using Microsoft Excel and SPSS 20 with significance set at 95% confidence interval and alpha at 0.05. Results: Forty-seven aircrew experiencing G-LOC/ALOC agreed to be part of the study and filled up the proforma after the episodes. However, only 42 proforma (31 G-LOC and 11 ALOC) was found suitable for the analysis. There was no statistical difference in heart rate (HR) measured during the rate of onset and G-level at which G-LOC and ALOC resulted. There was no difference in psycho-somatic manifestations of G-LOC and ALOC episodes. Conclusion: ALOC and G-LOC have similar manifestations and operational implications. There is ample evidence to suggest that ALOC is a manifestation of G-LOC syndrome rather than a separate entity.

Resumen

BACKGROUND: The risks associated with high positive Gz (+Gz) aerobatic flight, especially with respect to +Gz-induced loss of consciousness (G-LOC), are well known. Less appreciated is the effect of negative Gz (−Gz) flight on subsequent +Gz maneuvers, known as the “push-pull effect.” This is an example involving the loss of an F-16 and pilot that was caused by the push-pull effect.CASE REPORT: The mishap pilot (MP) was killed during a training flight when his F-16 crashed without an ejection attempt. The MP, while transitioning from prolonged −Gz flight to sustained +Gz flight, maneuvered the mishap aircraft (MA) from −2.06 Gz to +8.56 Gz in less than 5 s. At this point, there were only minimal control inputs for 5 s, indicating the MP experienced transient incapacitation, most likely due to G-LOC or almost loss of consciousness (A-LOC). The MP’s subsequent recovery attempt was interrupted by ground impact. The Accident Investigation Board (AIB) concluded the MP experienced G-LOC due to the push-pull effect.DISCUSSION: Since this is not the first time the push-pull effect has resulted in G-LOC mishaps, the adverse effects of such maneuvers should continue to be emphasized during military physiological training, as well as during general aviation (GA) aerobatics training. Furthermore, A-LOC, instead of being considered a discrete phenomenon, may need to be included in a broader G-LOC definition that encompasses the entire continuum of G-LOC and A-LOC.Metzler MM.

Resumen

Let R be a commutative ring with identity and let G(V, E) be a graph. The locating number of the graph G(V, E) denoted by loc (G) is the cardinality of the minimal locating set W ⊆ V(G). To get the loc (G), we assign locating codes to the vertices V(G)∖W of G in such a way that every two vertices get different codes. In this paper, we consider the ratio of loc (G) to |V(G)| and show that there is a finite connected graph G with loc (G)/|V(G)| = m/n, where m < n are positive integers. We examine two equivalence relations on the vertices of Γ(R) and the relationship between locating sets and the cut vertices of Γ(R). Further, we obtain bounds for the locating number in zero-divisor graphs of a commutative ring and discuss the relation between locating number, domination number, clique number and chromatic number of Γ(R). We also investigate the locating number in Γ(R) when R is a finite product of rings.

Resumen

Introduction: G-LOC is still a threat for aircrew of high performance aircrafts. It is evoked by a high level of +Gz acceleration causing a deficit of brain oxygenation. Although near-infrared spectroscopy (NIRS) was used to identify brain oxygenation decreases preceding G-LOC, it is not used regularly in aero-medicine research in Poland. Here, we report the physiological correlates of Almost Loss of Consciousness (A-LOC) that occurred during a research project. Method: During Dynamic Flight Simulation training on a human centrifuge one pilot experienced momentaneous confusion which was recorded on a camera. We post-hoc reviewed his vital signs, stroke volumes (SV), cardiac output (CO) obtained with bioimpedance rheography, and brain oxygenation (OX) measures with near-infrared spectroscopy on the forehead. Finally, we reviewed the recording of his eye movements obtained with video-oculography. Results: SV and CO measures were confounded by artefacts induced by anti-G straining manoeuvres (AGSM). However, OX measures demonstrated decreased brain oxygenation that lasted several seconds after the incident. Following the incident, the pilot’s pulse remained decreased for several seconds. Discussion: NIRS methodology seems to be resistant to artefacts created by muscles during AGSM. NIRS systems with a probing rate of 0.1 second might help detect upcoming A-LOC or G-LOC.

Resumen

Hurricanes are an important disturbance in the tropics that can alter forest ecosystem properties and processes. To understand the immediate influence of hurricane disturbance on carbon cycling, we examined soil labile organic carbon (LOC) in a Canopy Trimming Experiment (CTE) located in the Luquillo Experimental Forest of Puerto Rico. We trimmed tree canopy and deposited debris (CTDD) on the forest ground of the treatment plots in December 2014, and collected floor mass samples and 0–10 cm soil samples three weeks before the treatment, as well as at scheduled intervals for 120 weeks after the treatment. Within the first week following the CTDD treatment, the mean soil microbial biomass carbon (MBC) and soil LOC in the CTDD plots were significantly greater than in the control plots (soil MBC: 2.56 g/kg versus 1.98 g/kg, soil LOC: 9.16 g/kg versus 6.44 g/kg, respectively), and the mean turnover rates of soil LOC in the CTDD plots were significantly faster than in the control plots. The measured indices fluctuated temporally more in the CTDD plots than in the control plots, especially between the 12th and 84th week after the CTDD treatment. The treatment effect on soil LOC and its turnover rate gradually disappeared after the 84th week following the treatment, while higher levels of soil MBC in the CTDD plots than in the control plots remained high, even at the 120th week. Our data suggest that hurricane disturbance can accelerate the cycling of soil LOC on a short temporal scale of less than two years, but might have a longer lasting effect on soil MBC in a tropical wet forest.

Resumen

Gravity (G)-induced loss of consciousness (G-LOC), which is presumably caused by a reduction of cerebral blood flow resulting in a decreased oxygen supply to the brain, is a major threat to pilots of high-performance fighter aircraft. The application of cerebral near-infrared spectroscopy (NIRS) to monitor gravity-induced cerebral oxygenation debt has generated concern over potential sources of extracranial contamination. The recently developed NIR spatially resolved spectroscopy (SRS-NIRS) has been confirmed to provide frontal cortical tissue hemoglobin saturation [tissue oxygenation index (TOI)]. In this study, we monitored the TOI and the standard NIRS measured chromophore concentration changes of oxygenated hemoglobin and deoxygenated hemoglobin in 141 healthy male pilots during various levels of +Gz (head-to-foot inertial forces) exposure to identify the differences between subjects who lose consciousness and those who do not during high +Gz exposure. Subjects were exposed to seven centrifuge profiles, with +Gz levels from 4 to 8 Gz and an onset rate from 0.1 to 6.0 Gz/s. The SRS-NIRS revealed an ∼15% decrease in the TOI in G-LOC. The present study also demonstrated the TOI to be a useful variable to evaluate the effect of the anti-G protection system. However, there was no significant difference found between conditions with and without G-LOC in subjects with terminated G exposure. Further studies that elucidate the mechanism(s) behind the wide variety of individual differences may be needed for a method of G-LOC prediction to be effectively realized.

Resumen

Background: The phenomenon of almost loss of consciousness (A-LOC) is although known to the aviation fraternity since the 1980s, it is not well researched. Very few studies have attempted to elaborate the characteristics of A-LOC. The present study is a retrospective analysis which has endeavored to address the lacunae in literature. Materials and Methods: A retrospective analysis of the G training data in high-performance human centrifuge for a time span of 4 years (2009–2013) was carried out. Results: A total of 71 A-LOC incidents were reported and were analyzed for better understanding of A-LOC. On the basis of findings such as nystagmus, maintenance of postural tone, convulsions, amnesia, and dreams during A-LOC, neurophysiology of A-LOC has been hypothesized. Conclusion: The presence of nystagmus and maintenance of body posture suggest intact vestibulo-ocular reflex and sensory-motor tract, respectively. Non-recollection of dreams, amnesia suggests breach in memory and/ or information processing for higher functions. The mechanism of A-LOC in toto can be explained by regional differences in blood flow and vulnerability of cerebral centers to ischemic hypoxia. Convulsions in A-LOC could be attributed to hyperexcitability of nerve fibers due to hypoxia.

Resumen

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada
During high performance fighter aircraft manoeuvres, a fighter pilot may be exposed to a physiological phenomenon known as the “Push-Pull Effect” (reference (ref) [1]). This effect will alter the pilot’s homeostasis whereas blood flow to the brain will be increased during low negative normal acceleration (-Gz) and suddenly decreased during positive normal acceleration (+Gz). It has been hypothesized that this effect can lessen the Gtolerance of the human body thereby making the subject more susceptible to G induced Loss of Consciousness (G-LOC) (refs [2], [3] and [4]). G-LOC is not a desirable state for a pilot in a high performance aircraft such as a CF-18. To better understand and study the Push-Pull Effect on a fighter pilot, the Aerospace Engineering Test Establishment (AETE) and the Defence and Civil Institute of Environmental Medicine (DCIEM) produced an In-Flight Research (IFR) Program sponsored by the Canadian Forces (CF). The aim of this program was to measure the physiological response of relaxed test subjects, unprotected by a G-suit, when exposed to the Push-Pull manoeuvre in flight. This IFR would validate the centrifuge data and confirm that the Push-Pull Effect can occur in flight. This paper will present the instrumentation, design, telemetry system and installation methodology utilized to perform experimental physiological research on a high performance, ejection seat equipped fighter aircraft (CF-18). Also, preliminary results on the Push-Pull Effect, obtained through this IFR Program will be presented.

A low-frequency, low-g piezoelectric MEMS energy harvester has been designed. Theoretically, this new generation energy harvester will generate electric power from ambient vibrations in the frequency range of 200~30OHz at excitation amplitude of 0.5g. Our previous energy harvester successfully resolved the gain-bandwidth dilemma and increased the bandwidth two orders of magnitude. By utilizing a doubly clamed beam resonator, the stretching strain triggered at large deflection stiffens the beam and transforms the dynamics to nonlinear regime, and increases the bandwidth. However, the high resonance frequency (1.3kHz) and the high-g acceleration requirement (4-5g) shown in the testing experiments limited the applications of this technology. To improve the performance of the current energy harvesters by lowering the operating frequency and excitation level, different designs have been generated and investigated. Moreover, a design framework has been formulated to improve the design in a systematic way with higher accuracy. Based on this design framework, parameter optimization has been carried out, and a quantitative design with enhanced performance has been proposed. Preliminary work on fabrication and testing setup has been done to prepare for the future experimental verification of the new design.

Os nitretos, carbetos, boretos e óxidos de metais de transição na forma de nanopartículas, têm recebido nos últimos anos uma grande atenção no mundo científico, por apresentar propriedades físicas e químicas bem específicas, com aplicações diretas na indústria de alta tecnologia. Esta tese de doutorado foi motivada pelo desenvolvimento e avaliação experimental de uma nova configuração de reator, tubular e de fluxo cruzado, que promove um melhor contato entre as fases gasosas reagentes, possibilitando a execução da síntese de nanopartículas em temperaturas mais baixas. O reator consiste em um tubo de quartzo e um sistema de alimentação de gás NH3(g), dotado de chicanas que o redireciona promovendo uma distribuição mais homogênea deste nos orifícios de alimentação no reator. O TiCl4, uma vez vaporizado, é arrastado pelo argônio na direção axial do reator e o NH3 é injetado na direção radial central do reator. No aparato experimental desenvolvido foram avaliados os efeitos das variáveis do processo, temperatura, tempo espacial e pressão parcial do TiCl4 sobre o tamanho médio de cristalitos das partículas sintetizadas. Os resultados experimentais obtidos mostraram que no reator proposto foi possível produzir, na temperatura ambiente, nitreto de titânio (TiN) com 100por cento de conversão e tamanhos de cristalitos abaixo de 20 nm. Além da produção do TiN, também observou-se a formação de um co-produto, também particulado, o cloreto de amônio (NH4Cl). Nas análises por difração de Raios-X observou-se a presença de dióxido de titânio (TiO2) na forma de anatásio e de oxinitreto de titânio. O aparecimento destas fases pode ser explicado pela alta reatividade do nitreto de titânio com o oxigênio e vapor de água presentes na atmosfera e a sua elevada superfície específica.
Nitrides, carbides, borides and oxides of transition metals in the form of nanoparticles have received in recent years the attention in the scientific world, by their specific physical and chemical properties, with direct applications to the high technology industry. This thesis was motivated by the development and experimental evaluation of a new reactor concept, tubular and cross-flow, which promotes better contact between the gas-phase reactants, allowing the execution of nanoparticle synthesis at lower temperatures. The reactor consists of a quartz tube and a gas supply system (NH3), equipped with baffles that redirects the gas promoting a more homogeneous distribution of it in the holes that feed the reactor. The TiCl4 vaporized is carried by argon gas, in the axial direction, to the reactor and NH3 is injected in the radial direction in the central region of the reactor. In the experimental apparatus developed were evaluated the effects of process variables, temperature, space time and TiCl4 partial pressure, on average crystallite size of the synthesized particles. The experimental results obtained show that in the proposed reactor was possible to produce, at room temperature, titanium nitride with 100% conversion and crystallite size below 20nm. Besides the production of the titanium nitride was also observed the formation of a particulate co- product, the ammonium chloride (NH4Cl). In the X-ray diffraction analyzes was observed the presence of titanium dioxide (anatase) and titanium oxynitride. The occurrence of these phases can be explained by the high reactivity of titanium nitride with oxygen and water vapor present in the atmosphere and their high specific surface.

El objetivo del presente trabajo es analizar la forma en que se aplicará el artículo 41 G de la Ley sobre Impuesto a la Renta a los denominados trusts, e identificar los problemas que puedan surgir en la misma, recomendando modificaciones a la misma que pudieran mejorarla. Para la consecución del objetivo fijado, en primer lugar, se describirá la norma 41 G de la Ley sobre Impuesto a la Renta, su estructura y contenido, y la interpretación que ha dado el SII a la fecha a los preceptos en cuestión. Adicionalmente, se delinearán los objetivos y recomendaciones fijadas por la OCDE para la elaboración de las denominadas “CFC rules”, que se enfocan en enfrentar la erosión de las bases imponibles mediante el traslado de utilidades calificadas como “pasivas” a una jurisdicción de baja tributación. En segundo lugar, se definirán los trusts y sus características, se analizará la normativa legal y pronunciamientos administrativos que existen a su respecto en Chile. Y en tercer lugar, se identificarán los aspectos a debatir, principalmente referidos a la definición de control de las entidades analizadas y a posibles modificaciones a la norma actual que puedan mejorarla en relación a los trust; luego, se analizarán las reglas CFC en el derecho comparado, la aplicación de las mismas a los trusts y posibles conflictos que hayan surgido. Por último, se intentará dar una respuesta adecuada a las interrogantes planteadas, proponiendo que se considere a los beneficiarios como controladores si cumplen dos requisitos copulativos, esto es, que tengan un derecho formado sobre las utilidades que produzca el trust y que a su vez tengan facultades suficientes en la administración del mismo, en el sentido de poder movilizar las utilidades de una jurisdicción a otra

Resumen

Desde el éxito de la canción “Despacito” de Luis Fonsi & Daddy Yankee, el género urbano del reggaetón ha venido obteniendo mayor presencia en países de habla hispana. Así como este género musical se ha venido popularizando internacionalmente, han surgido diversos movimientos a favor de la igualdad de género y la defensa a los derechos de la mujer, y al mismo tiempo aparecían nuevas cantantes de reggaetón que se destacaban por demostrar el empoderamiento femenino tanto en las letras de las canciones como en los videoclips musicales. Por ello, el presente trabajo es un análisis narrativo audiovisual de los videoclips de reggaetón de Karol G entre los años 2017 y 2019 desde un enfoque de género para explicar la representación de la mujer en los videoclips como productos audiovisuales y publicitarios de alta difusión musical. Desde un paradigma interpretativo y un enfoque cualitativo se plantea un estudio de caso aplicado a los seis videoclips más visualizados de la artista en Youtube lanzados entre 2017 y 2019. Se propone analizar tres categorías relacionadas a la narrativa y la dirección de arte desde un enfoque de género; perfil de personajes, acciones y contexto.
Since the success of the song "Despacito" by Luis Fonsi & Daddy Yankee, the urban reggaeton genre has been gaining more presence in Spanish-speaking countries. Just as this musical genre has become internationally popular, various movements have arisen in favor of gender equality and the defense of women's rights, and at the same time new reggaeton singers appeared who excelled in showing female empowerment both in the lyrics of the songs as in the music video clips. Therefore, this work is an audiovisual narrative analysis of Karol G's reggaeton video clips between 2017 and 2019 from a gender perspective to explain the representation of women in video clips as audiovisual and advertising products with high musical diffusion. From an interpretative paradigm and a qualitative approach, a case study is proposed applied to the artist's six most viewed video clips on YouTube released between 2017 and 2019. It is proposed to analyze three categories related to narrative and art direction from an approach of gender; character profile, actions and context.

Resumen

AbstractThe drive towards a low carbon economy will lead to an increase in new lignocellulosic biorefinery activities. Integration of biorefinery waste products into established bioenergy technologies could lead to synergies for increased bioenergy production. In this study, we show that solid residue from the acid hydrolysis production of levulinic acid, has hydrochar properties and can be utilised as an Anaerobic Digestion (AD) supplement. The addition of 6 g/L solid residue to the AD of ammonia inhibited chicken manure improved methane yields by +14.1%. The co-digestion of biorefinery waste solids and manures could be a promising solution for improving biogas production from animal manures, sustainable waste management method and possible form of carbon sequestration.

Resumen

This work investigates a new concept of an electrostatically actuated resonant switch (EARS) for earthquake detection and low-g seismic applications. The resonator is proposed to operate close to instability bands of frequency-response curves, where it is forced to pull-in if operated within these bands. By careful tuning, the resonator can be made to enter the instability zone upon the detection of the earthquake signal, thereby pulling-in as a switch. Such a switching action can be functionalized for alarming purposes or can be used to activate a network of sensors for seismic activity recording. The EARS is modeled and its dynamic response is simulated using a nonlinear single degree of freedom model. Experimental investigation is conducted demonstrating the EARS capability of being triggered at small levels of acceleration as low as 0.02 g. Experimental data and simulation results are compared showing good agreement.
