Published: January 2024

Trajectory design for interplanetary missions is a challenging problem for which a wide range of algorithms have been proposed and used in the past. These algorithms range from completely problem-agnostic solvers, such as genetic algorithms, to methods that incorporate some degree of domain knowledge, like branch and pruning. In this paper, a novel algorithm is presented that is on the opposite side of this spectrum in the sense that it is expert-informed and fully tailored to the trajectory design problem. This algorithm is suitable for solving multi-gravity assist problems with or without thrust, as well as simpler problems like transfers to libration points or lunar missions. Its real-world applicability is enhanced by its ability to design end-to-end trajectories for missions with multiple phases.

The Python implementation of this algorithm, called SALTO (Search Algorithm for Large Trajectory Optimization), is based on two main ideas.

Firstly, the initial guess is only required to solve the problem from an energetic perspective and does not need to solve the phasing problem yet. This allows for large state and time gaps along the trajectory, which are systematically closed in a second step that exploits time shifts by full orbital periods or body rotations. The initial guess itself can be generated by any user-defined algorithm. Currently, implemented guess generators include techniques based on Tisserand Graphs, Lambert solvers, resonant transfer search and indirect methods.

Secondly, the algorithm is not expected to autonomously find all local minima for a problem. Instead, the user defines "tags," or category variables, that guide SALTO's search for solutions by indicating the expected structure of the search space. Examples of tags include the direction of infinite velocity at a planetary flyby, which can take the values “inward” and “outward”, and the resonance ratio of a same-planet transfer. SALTO will attempt to find a solution for all tag combinations in the problem.

SALTO is developed at ESOC as part of the MIDAS package and is Community Open Source (ESA Community License). It is accessible through the space-codev platform for European industry and academia.
Meteosat Third Generation : first AOCS in flight results from PFM-I1 LEOP and commissioning
Authors:   Thales Alenia Space, Cannes La Bocca, France, Dandré Pierre , Pirson Laurent , Ascani Livio , Sechi Gianfranco , Cerone Ernesto , Pessina Stefano
Published: January 2024

In December 2022, MTG PFM-I1, the first Meteosat Third Generation satellite, aiming at renewing the current Meteosat fleet, was launched on Ariane5 from Kourou, French Guiana. It will be followed by three others MTG-I (Imaging) Satellites and two MTG-S (Sounding) Satellites between 2025 and 2033. The attitude control concept changes from spinning satellites, which was the selected approach for the first and second generations, to a three-axes stabilization, offering better pointing performances as requested by the new generation of Meteosat instruments.

The Imaging satellites embark two main instruments: the FCI (Flexible Combine Imager, successor of the MSG instrument, it will offer 16 channels between 0.3 and 13.3 microns, and deliver a full image of Earth every 10 minutes.) developed by Thales Alenia Space and the LI (Lightning Imager) manufactured by LEONARDO, whose objective is the early detection of severe storms as they develop. The MTG-S satellites carry an Infrared Sounder and the Copernicus Sentinel-4 instrument. The two MTG satellites are mounted on a common Platform developed by OHB.

Thales Alenia Space leads the industrial consortium that is building the MTG family, with OHB as major partner.

The launch has been followed by a LEOP (Launch and Early Orbit Phases) period of 15 days led by EUMETSAT and TELESPAZIO from Fucino in Italy. EUMETSAT and Telespazio was helped by a ESA/TAS/OHB project support team. The handover to EUMETSAT has been achieved in the last days of 2022 after the spacecraft has successfully reached its final position on geostationary orbit and has triggered the mode NOM/FPM (Fine Pointing Mode, very accurate Earth Pointing mode used to performed the observation). The satellite is now ready to undergo an eight months of commissioning activities whose objective will be to assess the satellite and instruments functionality, operability and performance against the space segment requirements. It will include the payloads activation and operability using the Instrument Quality Tool(IQT).

This paper presents the AOCS MTG design and the way it has behaved during the LEOP phase, including some lessons learnt for the next FMs. Then it introduces the first main results of the commissioning phase, notably the FPM mode performances after instrument activation (pointing and attitude estimation with STR merging software, RW friction compensation, FCI scan pointing and compensation of instrument disturbance by PF, on-board orbit propagator… ).
SELECTING KEY FEATURES OF 3D OBJECT MODEL FOR RELATIVE POSE ESTIMATION
Authors:   DLR, Wessling, Germany, Klionovska Ksenia , Burri Matthias
Published: January 2024

The problem which is addressed in this paper refers to the discussion, how complex should be the

features extracted from the 3D mesh of a target, in order to get a stable and accurate relative pose estimation with monocular cameras during an On-Orbit Servicing (OOS) mission scenario.The process

of the key points extraction from 3D models is very challenging task because of following issues.

A) There is no strict definition how the interesting key features should be defined. In most cases it is

dependent on the features, which are going to be detected on the space object. Very common features

are corners or lines of the spacecraft, which can be detected from the visual data for further matching.

Considering these parts, we have to build a 3D key features of the target accordingly.

B) The up-to-date target model may be only available during the mission, e.g. reconstruction during

inspection phase. When we are still on the ground, we can only have an approximate 3D model of the

target. Then the question arises – how do we define the model key points on the ground before the

OOS mission takes place, if these points could be no more exist on the real space object? It should be

defined - if an on-board algorithm is needed or the data should be processed on the ground.

C) The limited computing power on board. The processing time for the model key extraction on

the ground is not a problem. The challenge is feature processing tasks in space using an On-Board

Computer (OBC). Dependent on the platform of OBC, the extraction of 2D image points with it

following matching should be fast enough to process live images.

We propose two models: the first model contains manually extracted key points; the second one has

key points extracted using HarrisKeypoint3D technique from PCL Library. The automatic process of

extracting 3D key points with HarrisKeypoint3D function can be used with different 3D meshes of

the space object. Thus, can be applied in different OOS missions. We are going to present the results

of relative pose estimation using two different models of the target mockup located at European Proximity Operations Simulator (EPOS), German Aerospace Center. Some camera images and ground

truth are collected for pose estimation tests also from EPOS facility.
DA MULTIDÃO AO PÚBLICO: IMAGENS, NARRATIVAS E TECNOPOLÍTICAS NA PRODUÇÃO DA POLARIZAÇÃO PÓS-2013
Authors: Camargo Alexandre , Ramos Katia
Published: January 2024

The protests in June 2013 brought to light new ways of mobilizing society and the emergence of actors who intensified conflicts in the public space. The first protests were attended by very diverse people and social groups, with different ideologies, who shared a general feeling of indignation. Between 2014 and 2015, the polarization takes place with the organization of new right-wing groups, reaching itk peak in the impeachment of former president Dilma Roussef in 2016. The article seeks to contribute to the debate on the social and political meanings of the June protests, carrying out a socio-genesis of the polarization that gripped the country. To this end, we propose a conceptual approach - the passage from the crowd to the public, as assumed by Gabriel Tarde - addressing aspects that are still lacking in analysis, such as the role of narratives, images, numbers and maps in the construction of public opinion about these events, with a focus on the media framing of these protests from 2013 to 2016.

GLOBAL EXPERIENCE OF GPS SYSTEM APPLICATION EFFICIENCY IN FOOTBALL
Authors: Metsoyan L. A. , Poghosyan M. S.
Published: January 2024

Football is a dynamic sport requiring a high level of physical and mental exertion from the players. The difference between victory and defeat can be a matter of inches or seconds, making performance optimization a critical aspect of the game. Technological advances in recent years have given teams innovative tools to increase their own performance. Among these technological tools, global positioning technology (GPS) has become popular in the football industry.
The use of GPS technology in football has changed the way teams approach training and performance analysis. GPS technology provides coaches with real-time data on player movement and performance metrics such as distance covered, speed, acceleration, deceleration and heart rate. This data can be used to optimize training programs and improve player performance by identifying areas for improvement.
Compared to traditional performance analysis methods such as video analysis or subjective observation, GPS technology provides objective data that can be analyzed more effectively. This allows coaches to make more reasonable decisions regarding player selection and training programs. The purpose of the research is to study the main role and features of using GPS technology in the football coach activities and the advantages of implementing GPS technology in the field of physical culture and sports, its comparison with traditional methods, as well as possible problems that may be associated with the implementation of GPS technology.
The use of GPS technology in football has become even more popular in recent years and offers many benefits to teams and coaches. GPS technology provides objective data and real-time monitoring, allowing coaches to make reasonable decisions based on real facts rather than subjective observations.
THE PROBLEM OF OBSERVING THE MAXIMUM OF A SUPERPOSITION WAVE FIELD
Authors: Khachatrian A.Zh. , Petrosyan A.V. , Khoyetsyan V.A.
Published: January 2024

The well-known Laue condition determining the intensity maximums of diffracted on an ideal crystal structure plane wave is discussed. Initially the consideration is performed for the near observation region and after that by means of applying the corresponding approximation the expression of superposition field is presented as a sum of plane waves. So, the description of the superposition field for the far observation region is made. It is proved that the Laue conditions, which are restrictions imposed on the values of the scattering wave vector, is more correctly to be considered as a pair of two conditions. The first condition relates to the wave vector of an incident wave and the second condition relates to the wave vector of an observation direction. In other words, to observe the maximums, it is not enough when only the difference (the scattering wave vector) of these two vectors satisfies the Laue condition. To observe the maximums, it is necessary that each of these vectors separately, i.e. the wave vector of the incident wave and the wave vector of the observation direction satisfy the Laue condition. It is shown that such a doubling of the maximum conditions leads to a decrease in the number of the observed maximums compared to the condition imposed only on the scattering wave vector.
Within the framework of the previously developed method, a number of formerly known results related to the kinematic theory of diffraction of a plane wave by an ideal crystal structure were reproduced. It is assumed that the generation of secondary waves of each atom of the crystal is provoked by the presence in the volume of the crystal of a primary field, which in Fraunhofer formulation is considered in the form of a plane and time-harmonic wave. The intensity distribution, as well as the positions of the maxima of the diffraction pattern, was studied depending on the spatial parameters of the crystal lattice.

The importance of microbes in plastics degradation: A sustainable approach A Short Review
Authors: Dutta Esha , Ghosh Keshab , Pal Shovana , Laha Aritri
Published: January 2024

Since the 1950s, plastics have been frequently utilized due to their affordability and durability. The widespread use of plastics poses a great risk to the environment. As plastics are non-degradable and have resistance to moisture, they get piled up in the environment, causing soil and water pollution. Global food chains are suffering due to the heavy use of plastic. Bioremediation is a technique that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. Using microorganisms to break down plastic and turns it into low molecular weight molecules, that are safe for the ecosystem is the most cost-effective and environmentally beneficial way to reduce the amount of plastic in the environment. Microorganisms degrade plastics by secreting metabolites such as polyhydroxyalkanoate depolymerases, which help in plastic breakdown. This review outlines the potential of different bacteria and fungi that can breakdown plastics and explains the general procedure of microbial biodegradation of plastics and also the different types of enzymes used by the microorganisms to degrade plastics.

Politička laicizacija analizira se s obzirom na stupnjeve njezina povijesnog razvoja: kao prvotna autoritarna i antiklerikalna laicizacija, kao drugotna laicizacija otvorenog pluralizma i kao laicizacija koja se u radu opisuje kao »fluidna« jer u velikoj mjeri odstupa od rigidnog i antiklerikalnog suprotstavljanja dominantnim Crkvama u oblicima javno-pravne institucionalizacije odvojenosti vjerskih zajednica i države te od antiklerikalnih obrazaca političkog i javnog djelovanja. S obzirom na to da se rad u velikoj mjeri oslanja na istraživanja Marcela Gaucheta, Jeana Baubérota, Micheline Millot, Martina Rohnheimera, Jeana Picqa, Neila MacCormicka, Michela Foucaulta i drugih, nastoji se istražiti koliko je promjena i transformacija uloge identitetâ pridonijela promijenjenoj ulozi političkog i javnog djelovanja opisanog kao doba prihvaćanja (priznavanja) identitetâ, a koje ima svoje reperkusije na formate političke laicizacije.
Poimanje invaliditeta u pontifikatu Ivana Pavla II.
Authors: Vuk Grgić Martina
Published: January 2024

Ivan Pavao II. je tijekom svog dugog pontifikata unutar pojedinih enciklika, govora i poruka pokazao veliko zanimanje i suosjećanje za invaliditet i patnju čovjeka. Tomu svjedoči činjenica da je 3. prosinca 2000. godine proglasio Jubilarni dan osoba s invaliditetom, a prije toga 13. svibnja 1992. godine i Međunarodni dan bolesnika. U svojoj teološkoj i etičkoj misli i pontifikatu pokazao je i apelirao na važnost i poštovanje metafizičke naravi osobe i njezina dostojanstva, bez obzira na životnu situaciju ili mentalnu sposobnost, prije svega kao onu koja je stvorena na sliku Božju, što uključuje i osobe s invaliditetom. Papa Ivan Pavao II. također je pokazao i izrazitu skrb i interes za očuvanje čovjekova dostojanstva unutar društvenih struktura. Svrha je ovog članka ukazati na zauzetost Ivana Pavla II. za osobe s invaliditetom unutar njegova dugogodišnjeg pontifikata te istražiti u čemu je posebnost i originalnost toga pristupa, a u čemu se razlikuje od suvremenog poimanja invaliditeta s obzirom na modele invaliditeta i znanja koja su nam o toj temi dostupna. U tome ćemo se voditi analizom njegovih nagovora, homilija i poruka upućenih osobama s invaliditetom te implicitno selektivnim izborom njegovih enciklika i apostolskih pisama poput Evangelium vitae i Salvifici doloris u kojima poziva na brigu i zauzetost za dostojanstvo drugoga, upućujući na poštovanje cjelovitosti osobe kao i na vrijednosti čovjekova trpljenja.

Published: January 2024

Presentación del caso. Se trata de un masculino de 49 años, con historia de un trauma abdominal cerrado con un objeto contuso sin alteraciones hemodinámicas. La ecografía focalizada de traumatismos resultó positiva a líquido libre en la cavidad abdominal en tres ventanas. Intervención terapéutica. Fue sometido a múltiples laparotomías exploratorias con lavados de cavidad abdominal posterior a presentar un cuadro de abdomen séptico Björk 4, quien después de 38 días de estancia intrahospitalaria presentó una fístula enteroatmosférica que causaba un déficit nutricional grande. En una intervención quirúrgica se realizó el cierre de la fístula enteroatmosférica, con el hallazgo de tejido óseo trabecular en cavidad abdominal, correspondiente a osificación heterotópica intraabdominal de formación reciente. Evolución clínica. Luego de la anastomosis del intestino delgado presentó signos de obstrucción intestinal, a causa de esto, se realizó una nueva laparotomía exploratoria, en la que se encontró tejido óseo adherido al mesenterio del intestino delgado que generó una obstrucción completa, se extirpó el material óseo y se logra restablecer el flujo intestinal liberando la obstrucción en el intestino delgado.

Authors: Rivera Rosales David Daniel , Tejada Peña David Alexander
Published: January 2024

Introducción. La enfermedad renal crónica es responsable de aproximadamente 2,4 millones de defunciones a nivel mundial. La supervivencia a los cinco años después de iniciar diálisis se encuentra entre un 39 a 60 % dependiendo del país. Objetivo. Describir la situación epidemiológica de los pacientes con diálisis y analizar los factores que influyen en la supervivencia de pacientes a cinco años de iniciar tratamiento sustitutivo renal en El Salvador. Metodología. Estudio de cohorte retrospectiva de los pacientes incluidos en el Registro Nacional de Diálisis y Trasplante Renal desde enero de 2016 hasta febrero de 2023. El seguimiento se comenzó al inicio de la diálisis, el evento de interés fue la muerte del paciente. Se utilizó el método de Kaplan-Meier para determinar la supervivencia al año y a los cinco años y la regresión de Cox con el modelo de Royston-Parmar para analizar los factores que influyen sobre la supervivencia a los cinco años. Resultados. El estudio incluyó 7088 pacientes, la supervivencia a uno y cinco años fue del 79,5 % (IC 95 %: 78,6-80,5) y 50,6 % (IC 95 %: 49,1-52,1) respectivamente. La regresión de Cox para la edad de inicio de tratamiento resultó en un hazard ratio de 1,02 (IC 95 %: 1,01-1,02), mientras que para el oficio de ser agricultor el hazard ratio fue 1,1 (IC 95 %: 1,01-1,18) y para la etiología hipertensiva el hazard ratio fue de 0,7 (IC 95 %: 0,64-0,78). Conclusión. La edad de inicio de tratamiento y el ser agricultor están asociados con una menor supervivencia a cinco años en pacientes con diálisis.
Seroprevalencia de Toxoplasma gondii y su relación con trastornos mentales en adultos
Authors: Lemus Buitrago Luis Felipe , Osegueda Ascencio Diego José , Fuentes Rodríguez Verónica Cecilia
Published: January 2024

El Toxoplasma gondii es un parásito que se encuentra, aproximadamente, en el 30 % de la población humana. Durante los últimos años se ha evidenciado que la infección latente puede ser un factor de riesgo para el desarrollo de trastornos mentales; particularmente para la esquizofrenia, ansiedad, trastornos bipolares y trastornos de conducta. La asociación con los trastornos neuropsiquiátricos pueden explicarse por la influencia que tiene el parásito sobre la expresión de múltiples neurotransmisores; entre ellos la dopamina. Se realizó una búsqueda en las bases de datos PubMed y SciELO de 2015 a 2023, se seleccionaron artículos originales y de revisión de revistas científicas internacionales, en idiomas inglés y español con el objetivo de describir la relación entre la seroprevalencia de T. gondii y el desarrollo de trastornos mentales en población adulta. Existe relación entre los trastornos mentales en la población adulta con la infección por Toxoplasma gondii y este aumenta la posibilidad de desarrollar esquizofrenia y depresión en individuos sin historial previo, y que podría exacerbar cuadros psiquiátricos previos con dificultad en el tratamiento. Sin embargo, no todos los datos estadísticos establecen una relación directa, algunos estudios demuestran una asociación, ciertos datos son discordantes, lo que abre una puerta para futuras investigaciones.
Alteraciones genéticas asociadas a enfermedad de Parkinson y Alzheimer: evolución y respuesta al tratamiento
Authors: Quezada Rivera Rodrigo Antonio , Bonilla Rodríguez Francisco Esteban , Benavides Romero Marcela Alejandra , Peña Martínez Susana Lissette
Published: January 2024

La enfermedad de Parkinson y Alzheimer son las enfermedades neurodegenerativas más frecuentes a nivel mundial. Tienen etiología multifactorial, entre ellas, la genética; y son motivo de interés en la investigación científica actual. Se realizó una revisión narrativa con el objetivo de determinar las alteraciones genéticas asociadas a estas patologías, además su influencia en la evolución y respuesta al tratamiento de ellas. Se consultaron artículos originales, revisiones bibliográficas, sistemáticas, metaanálisis en inglés y español, con fecha de publicación entre el 1 enero de 2018 y el 20 de mayo de 2023, en bases como PubMed y Medline. Se utilizaron los términos MeSH «Alzheimer Disease», «Parkinson Disease», «Drug Therapy» y «Mutations». El riesgo hereditario para la enfermedad de Parkinson suele ser poligenético, sin embargo, existen genes relacionados con mutaciones monogénicas. Se identifican alteraciones en genes de α-sinucleína, glucocerebrosidasa y quinasa 2 rica en leucina que se relacionan con mayor riesgo de desarrollar Parkinson, además de variaciones en el cuadro clínico y edad de inicio de síntomas. En cuanto a la enfermedad de Alzheimer, las alteraciones en los genes de la proteína precursora amiloide, presenilina 1 y 2 se relacionan con la forma familiar de la enfermedad; por otra parte, las de apolipoproteína E4 se han identificado en la forma esporádica, por lo que se consideran como el factor de riesgo genético más importante para su desarrollo.

Purpose: The study provides answers to queries about how Ghana's unemployment rate is affected by inflation as well as effective strategies Ghana's government can use to address challenges in the current economy Methodology: In order to forecast future results, this study examined the changes in Ghana's unemployment and inflation rates between 1991 and 2021. Annual time series statistics for these attributes were compiled using data from secondary sources Findings: The Phillips curve shows how the unemployment and inflation rates are related. The ADF test revealed stationary inflation and unemployment rates at the initial variation, while the Johansen cointegration test revealed a single cointegrating equation at a 10 level of significance. Using the Vector Error Correction Model (VECM) model at lag 3, the short- and long-term interactions between Ghana's inflation and unemployment rates were investigated. Practical Implications: The findings indicate that Ghana's unemployment rate and inflation rate have a long-term positive association, which defies the Phillips curve. The estimate of 0. 2035 for the Equilibrium Error Correction Coefficient (ECM) is significant and has the appropriate sign. This means that after a shock, everything will quickly return to normal. Originality/value: The research analysis significantly adds to the body of knowledge on Ghana's projected future returns between inflation and unemployment rates. An economy depending on the nation's unemployment problems and the current state of the economy. The outcome demonstrated a long-term, positive link relating to rates of unemployment and price increases. As a result, the government should create an economic plan to permanently reduce the rate of unemployment and inflation.
