Published: May 2022

Introduction: The high incidence of sports injuries in elite athletes is a concern in sports medicine. A broad vision of sport injuries in Colombia and its pathophysiology can be achieved in the scope of genomics, which could respond to numerous sports injuries from the Identification of single nucleotide polymorphism that lead to disabilities that affect the health of athletes and often distance them from the field of play. Objective: To determine the association of single nucleotide polymorphisms in various genes with sports injuries in soccer. Material and methods: We searched in the databases PubMed, ScienceDirect and EBSCO for studies published in the last 6 years to January 2020, including studies in English and Portuguese, corresponding to case-control clinical studies, where the experimental group were soccer practitioners and controls were supposedly healthy people. The final papers were assessed for quality and bias using the Jadad scoring scale or Oxford quality scoring system. From the data obtained, heterogeneity was identified with the I2 test and the Q statistic, for the estimation of the effect in the cohort studies the odds ratio and p value <0.05 were used, obtaining the forest plots of each gen. Results: 10 out of 1928 studies were selected, finding a degree of heterogeneity in all studies, such as the risk of injury to ACNT3 SNP (OR = 0.98, 95% CI 0.64-1.50), MMP (OR = 1.16, 95% CI 0.86 - 1.58, p = 0.33), TIMP2 (OR 1.03 95% CI 0.65-1.63), VEFGA (OR 0.98 95% CI 0.70-1.37). Conclusion: The studies showed moderate heterogeneity with statistical significance for the ACTN3 and TIM SNPs, providing a pathway for future studies that relate to sports injuries.

Published: May 2022

La pérdida de un ser querido por suicidio puede ser uno de los eventos más estresantes de la vida. Los factores de riesgo y protección asociados a cada caso pueden favorecer o dificultar el procesamiento de la pérdida. Se presenta un caso de trastorno de duelo complejo persistente en el que se aplica el Protocolo Mindfulness para la Aceptación del Dolor, las Emociones y el Duelo. La paciente mejora tras la intervención, observándose que ya no puntúa en trastorno de duelo complejo persistente, ni sintomatología ansiosa de forma significativa, ha disminuido su afecto negativo y aumentado su autocompasión, afecto positivo y bienestar psicológico. Concluimos que se hace necesaria una evaluación integral desde el sistema sanitario para poder atender a los pacientes que presenten trastorno de duelo complejo persistente de manera multidisciplinar. La intervención psicológica puede disminuir los costes económicos, sanitarios y personales. MÉD.UIS.2021;34(3): 85-92.

Transformation of Prospective Teachers’ Pedagogical Beliefs during a Pre-Service B.Ed. Programme in Pakistan
Authors: Dayan Uzma , Khan Muhammad Ilyas , Ahmad Sohail
Published: May 2022

Teachers’ pedagogical beliefs play a vital role in the process of teaching and learning. These beliefs are often reflected in their practices which lead to the formation of their instructional decision making. Pre-service teacher education programs are offered in many universities of Pakistan with the aim to prepare professional teachers with strong beliefs in the value of teaching profession. Therefore, this qualitative case study aimed to explore the transformation of pre-service prospective teachers’ beliefs regarding teaching skills during a Bachelor of Education (B.Ed.) program in the context of Khyber Pakhtunkhwa (KP). The data were collected from eight participants through semi-structured interviews in two phases: before teaching practice and after teaching practice. Findings revealed that pre-service teachers joined B.Ed. program with certain traditional beliefs about teaching skills that were rooted in their past experiences as students. The transformation of those beliefs took place at the time of teaching practice in a real classroom. The paper concludes that only coursework of pre-service teacher education might not be sufficient to transform prospective teachers’ beliefs, rather the teaching practice should be a contributory factor in transforming their pedagogical beliefs. This could mainly be attributed to the prospective teachers’ practical experiences in real classroom situations during the teaching practice. The study has important implications for teacher educators and educational researchers in terms of highlighting the important role of teaching practice in the professional preparation and development of prospective teachers.

Published: May 2022

A review of literature on mobile technology in EFL learning environment has indicated the growth, trends and practices of smartphones and mobile apps adoption both in classroom and outside classroom settings. However, little has been known on how EFL teachers perceived such trends and current practices and how they plan for future teaching. This study attempted to explore teachers’ responses to trends and practices of mobile technology adoption and their future teaching plan. To this end, a qualitative design was adopted with two consecutive research procedures: a systematic review on the selected trends and practices analysis studies on mobile technology for language learning practices and a survey through a semi-structured interview. Five EFL teachers (three females and two males) from secondary school level were interviewed using six open-ended questions. Findings of the study revealed that teachers perceived positively towards the trends and practices of mobile technology in and outside language learning classroom. Teachers perceived motivation as a main driver to incorporate mobile technology. Some of motivations frequently cited in the interviews with the sampled teachers revealed the current trends and practices of blended learning practices among Indonesian teachers, including the perceived benefits of mobile technology adoptions and the effect of mobile technology on teaching and learning practices and students’ characteristics. Three challenges were identified when technology was incorporated for learning namely infrastructure related issues, teacher technological knowledge and education policy.

Turystyka zrównoważona – pytania o naukową użyteczność koncepcji
Authors: Mika Mirosław
Published: May 2022

Celem artykułu jest przedstawienie, w świetle stanu badań, najpoważniejszych zastrzeżeń formułowanych wobec koncepcji zrównoważonego rozwoju turystyki, a także ograniczeń wdrażania jej założeń w praktyce. Wskazano m.in. na niejednoznaczność interpretacji pojęcia „zrównoważenie” i wynikające z tego konsekwencje metodologiczne w studiach nad turystyką, problem pomiaru oraz oceny stopnia „zrównoważenia” zjawisk i procesów w turystyce, a także na społeczny sprzeciw wobec propozycji samoograniczania konsumpcji turystycznej oraz sytuację niestabilności warunków klimatycznych i gospodarczopolitycznych, uniemożliwiających implementację zasad zrównoważonego rozwoju na obszarach recepcji turystycznej. W konkluzji rozważań wysunięto tezę o potrzebie dookreślenia nowego paradygmatu turystyki zrównoważonej, nieodwołującego się wprost do imperatywu zgodnego (harmonijnego) łączenia wielu celów rozwoju turystyki i wartości.

Published: May 2022

Przedmiotem pracy jest prezentacja wybranych zjawisk lodowych na akwenach południowego wybrzeża Bałtyku mogących mieć znaczenie turystyczne. Na podstawie własnych obserwacji i badań w latach 2002–2014 analizowano ciekawe zjawiska lodowe. Do tego celu przydatne były fotografie zjawisk lodowych (20), dotyczące głównie lodu zdeformowanego (wały śryżowe, zwały lodowe, nasunięcia lodu). Fotografie te dotyczyły głównie brzegu morskiego (8) i zalewów (7), a także jezior (5). Przedstawiono krótkie opisy wybranych zjawisk lodowych, zwracając uwagę na ciekawe formy i ich genezę. Przedstawione opisy mogą zainspirować potencjalnych turystów do obserwowania i poznawania akwenów zalodzonych. Taka turystyka lodowa (ice tourism) mieściłaby się w zakresie turystyki poznawczej, przyrodniczej, specjalistycznej, pieszej, zimowej, okresowej, a nawet epizodycznej.

Trajectory Anomaly Detection based on Similarity Analysis
Authors: Quispe Torres Gerar Francis , Enciso Rodas Lauro , Vera Olivera Harley , Garcia Zanabria Germain
Published: May 2022

Automatic trajectory processing has multiple applications, mainly due to the wide availability of the data. Trajectory data have a significant practical value, making possible the modeling of various problems such as surveillance and tracking devices, detecting anomaly trajectories, identifying illegal and adverse activity. In this study, we show a comparative analysis of the performance of two descriptors to detect anomaly trajectories. We define Wavelet and Fourier transforms as trajectory descriptors to generate characteristics and subsequently detect anomalies. The experiments emphasize performance in the description in the coefficient feature space. For that, we used unsupervised learning, specifically clustering techniques, to generate subsets and identify which are irregular. The implications of the study demonstrate that it is possible to use descriptors in trajectories for automatic anomaly detection and the use of unsupervised learning methods that automatically segment the required information. The performance and comparative analysis of our study are demonstrated through experiments and case studies considering synthetic and real data sets that leave evidence of our contribution.

O câncer de pele é um dos cânceres que mais agrava os problemas de saúde pública. Dentre os tipos de câncer, o melanoma é o mais agressivo. Seu diagnóstico precoce é fundamental para aumentar a possibilidade de tratamento adequado, visando reduzir a taxa de mortalidade. Os dermatologistas geralmente usam métodos manuais para diagnosticar lesões de pele. Além de demorados por serem realizados manualmente, esses métodos podem apresentar resultados diferentes para a mesma lesão quando analisados ??por diferentes especialistas. Portanto, um diagnóstico automatizado pode ser necessário para lidar com esse problema e evitar testes invasivos. Segmentar a lesão cutânea na imagem dermatoscópica pode ser fundamental, pois se trata de umatarefa essencial no processo de análise de imagens. No presente trabalho, um modelo de Rede Neural Convolucional (CNN), baseado na U-Net, é proposto para segmentar a lesão em imagens dermatoscópicas . Este modelo obteve um Jaccard de 0,833 para a base ISIC 2017 e 0,850 para a base ISIC 2018. O modelo proposto possui uma arquitetura mais simples, exigindo menos recursos computacionais. Para verificar a eficácia do método proposto, realizamos um estudo de ablação e experimentos comparativos com outros métodos.
Short-time prediction of DNS queries using deep learning and pre-trained word embedding
Authors: Jorge Merlino , Rodríguez-Bocca Pablo
Published: May 2022

Word embeddings are used in natural language processing to group semantically similarwords. In this paper, we create word embeddings for Internet Domain Names (DNS)from corpora of anonymized DNS queries from an Internet Service Provider. We use eachembedding as a layer of a recurrent neural network (RNN) that works as a LanguageModel for the DNS queries generated by the users. We use these RNNs to predict thenext DNS query in two different cases. A first case tries to predict the next domain queryfrom the DNS server’s point of view so the corpus is close to the original log data. Asecond case tries to predict the next domain queried by a user from the user’s point ofview. Here the corpus has larger preprocessing.We show that this procedure has good accuracy for the DNS server-side problem, butlow accuracy for the user-side problem. Moreover, we show that training the same RNNwithout using the pre-trained embedding takes more time and is substantially less accu-rate. These results have practical applications for the service’s latency reduction, cacheoptimization in recursive DNS servers, automatic filtering of inappropriate domains, anddetecting anomalies.
Evaluation of Compliance Requirements for collaborative business process with process mining and a model of generic compliance controls
Authors: González Laura , Delgado Andrea , Canaparo Juan , Gambetta Fabián
Published: May 2022

The daily operation of organizations leaves a trail of the execution of business processes (BPs) including activities, events and decisions taken by participants. %, as a basis for process improvement. Compliance requirements add specific control elements to process execution, e.g. domain and/or country regulations to be fulfilled, enforcing order of interaction messages or activities, or security checks on roles and permissions. As the amount of available data in organizations grows everyday, using execution data to detect compliance violations and its causes, can help organizations to take corrective actions for improving their processes and comply to applying rules. Compliance requirements violations can be detected at runtime to prevent further execution, or in a post mortem way using Process Mining to evaluate process execution data against the specified compliance requirements for the process. In this paper we present a BP compliance Requirements Model (BPCRM) defining generic compliance controls that can be used to specify specific compliance requirements over BPs, that are used as input to assess compliance violations with process mining. This model can be seen as a catalogue that includes a set of predefined compliance rules or patterns in one place, helping organizations to specify and evaluate the compliance of their processes.
Practice Education in Wales: progress and limitations
Authors: Mohammed Imran
Published: May 2022

In this paper I discuss the role of the Practice Educator and the need for further exploration of research in Wales. I explain in this paper that there is a 'role' conflict between practice assessor and 'educator'. The literature that is currently available on Practice Education includes the perspectives of Practice Educators in England. I therefore argue that a 'body of knowledge' is required to better understand the role of the Practice Educator in Wales.
Understanding polyamory as a form of concurrency to enhance HIV programmes in South Africa: The need to re-conceptualize the partner reduction policy
Authors: Molefi Stanley , Gutura Priscilla , Eskell-Blokland Linda
Published: May 2022

A conceptual framework derived from three inter-related theories of social cognitive theory, constructivism and the meaning-making model, was used to investigate the group of relations between polyamorous relationships, safer sex practices and HIV. Using purposive sampling seven participants who were in polyamorist relationships in three provinces in South Africa: Gauteng, Cape Town and Northern Cape were interviewed to collect data. Interpretative phenomenological analysis was employed as the data analysis method. The findings of this study revealed that many of the participants who were involved in polyamorous relationships were concerned about their health and well-being. Therefore, in most of these relationships, the participants required of their secondary partners to disclose their HIV status and also test for STDs. Also, in all of the participants’ polyamorous relationships there were sexual rules and agreements that were set up in order to limit exposure to HIV. Furthermore, high level of communication strategies was employed to improve honesty and trust among all of the partners involved. The coping strategies that were adopted by all of these participants in order to deal with familial and societal rejection of their involvement in concurrency included forming psycho-social support networks. These findings show that there is a need to re-conceptualize the partner reduction policy in order to accommodate the perspectives and needs of people who are involved in concurrent partnerships. Further, social work is called upon to be aware and sensitive to polyamorous relationship in both education and practice.
Male partner involvement in health interventions: A systematic review of best practices in Sub-Saharan Africa
Authors: Chereni Admire , Nyathi Nhlanganiso , Mbizo Justice
Published: May 2022

Health promotion programmes aimed at the involvement of men are implemented in a complex cultural and socio-demographic context that reifies persistent unequal gender relations. The explanations and evidence for the mechanisms by which male involvement facilitates health and wellness, are, however, less clear. Drawing on findings from a qualitative systematic review of peer-reviewed studies, this article synthesises the literature on health, social policy, and programme interventions for improving male partner involvement to promote sexual and reproductive health, HIV and AIDS health outcomes in sub-Saharan Africa (SSA). Findings suggest that combining approaches such as mass education campaigns and health and social care programmes, targeting both men and women, improves male participation. Finally, enhancing participation of both men and women in the planning, implementation, and evaluation of health program programmes, can lead to positive gender role transformations and positive health and social care outcomes in Sub-Saharan Africa.

Early Stopping Effectiveness for YOLOv4
Authors: Muhammad Afif Rana , Utomo Hamzah Prasetio , Hidayatullah Priyanto , Syakrani Nurjannah
Published: May 2022

Background: YOLOv4 is one of the fastest algorithms for object detection. Its methods, i.e., bag of freebies and bag of specials, can prevent overfitting, but this can be combined with early stopping as it could also prevent overfitting.
Objective: This study aims to identify the effectiveness of early stopping in preventing overfitting in the YOLOv4 training process.
Methods: Four datasets were grouped based on the training data size and object class, These datasets were tested in the experiment, which was carried out using three patience hyperparameters: 2, 3, and 5. To assess the consistency, it was repeated eight times.
Results: The experimental results show that early stopping is triggered more frequently in training with data below 2,000 images. Of the three patience hyperparameters used, patience 2 and 3 were able to halve the training duration without sacrificing accuracy. Patience 5 rarely triggers early stopping. There is no pattern of correlation between the number of object classes and early stopping.
Conclusion: Early stopping is useful only in training with data below 2,000 images. Patience with a value of 2 or 3 are recommended.
Keywords: Early Stopping, Overfitting, Training data, YOLOv4

Se realizó el análisis de ciclo de vida (ACV) de una biorrefinería (BRF) de seis etapas tipo HMEZS-NN (hidrógeno, metano, ácidos, solventes, enzimas, sacarificados y nanobiopartículas), la cual procesa la fracción orgánica de residuos sólidos urbanos para obtener bioenergías y productos de valor agregado (concentrado de ácidos orgánicos y solventes, enzimas celulolíticas y xilanolíticas, y nanobiopartículas) para la industria de remediación de aguas. Se analizaron las 18 categorías de impacto de punto intermedio con el método ReCiPe jerárquico 2016. Se encontró que la BRF es autosuficiente en energía total, en una cantidad cercana a los 600 MJ, que consiste totalmente en energía eléctrica de alto y bajo voltaje, pero deficitaria en un 37 % en el rubro calor. Con un análisis de sensibilidad ad hoc, se encontró que subiendo el valor de la fracción de sólidos fermentados que genera el biorreactor H y que se destina al biorreactor metanogénico M del 40 al 54.12 %, la BFR podría ser autosuficiente en calor y además generar un execedente muy significativo de energía eléctrica. Las etapas que contribuyeron significativamente a varias de las categorías de impacto de punto intermedio fueron las etapas de producción de enzimas (Z) y nanopartículas (NN), y de varios procesos anidados en ellas. Con menor frecuencia, y actuando sobre categorías particulares, se colocaron la etapa M de metanogénesis (en calentamiento global, por ejemplo), hidogénesis y E (extracción de ácidos orgánicos), importante para el deterioro de ozono estratosférico, por ejemplo. En las diversas categorías de ecotoxicidad se notó tendencia marcada a la contribución predominante de Z y NN, y de los procesos relacionados con purificación de residuos de la producción de ácido fosfórico y varios procesos de tratamiento de residuales de minería, de carbón, cenizas y jales. La mayoría de esos procesos no son explícitos en la base de datos del Software.
Supernova Plasma Effects on Extragalactic Light Fields
Authors: Marko Paul
Published: May 2022

Simulations based on Supernova (SN) observations predict several galactic SN explosions (SNe) occur every century. Unlike SNes within the Interstellar Medium (ISM) where ambient gas generally absorbs blast waves within a million years, SNes occurring in a rarified environment outside of the (ISM) generate blast waves which remain in a high velocity free expansion phase for more extended periods. The SN blast wave forms an expanding spherical shell and when multiple blast waves intersect, the overlapping region naturally takes the form of a ring, an arc, or an Einstein Cross structure. The analysis shows the high velocity plasma establishes a medium with permeability which drives the index of refraction greater than 1. As a result, when a shock discontinuity forms in the overlapping region, light is reflected from the host galaxy which exposes the intersecting blast wave regions. The expanding shells are shown to induce an achromatic redshift to the reflected light consistent with those measured for gravitational lenses. Further, it is shown that a Hubble equation for a blast wave around the Milky Way Galaxy can be parameterized to align with measured redshifts of extragalactic light fields over a wide range of distances.

The way flipped classrooms are perceived and even practised by teachers is sometimes approximative. For example, while the Covid-19 pandemic has pushed many universities to adopt distance learning, flipped classrooms have often been mentioned as a solution in that context. This inducement maintains a confusion between flipped classrooms and distance learning that might be detrimental for both students and teachers. Moreover, embarking on a new pedagogical practice such as flipped classroom could be intimidating and time-consuming. For these reasons, this article aims to share some tips for implementing a flipped classroom, with examples from biology and biochemistry. Based on our own experiences but also on the current scientific literature, we propose to structure the advises around three phases: Preparation, Implementation, and Follow-up. In the preparation phase it is advised to not only plan to invert time but also say it, as well as to identify (or create) resources for learning in autonomy. In the Implementation phase it is suggested to i) Be explicit in the acquisition of knowledge, and foster students' autonomy; ii) Explore active learning in class; iii) Develop skills of cooperation and sharing; and iv) Differentiate. In the follow-up phase it is proposed to i) Evaluate; ii) Take care of the logistics and your posture; iii) Document your flipped classroom and iv) Share.

Coaxial rotors can be found in multirotor vehicles for the added thrust compared to independent rotors while keeping similar area footprints but, performance losses should be considered. This experimental study analyzes the effects of varying motor throttle and propeller pitch values in motor-propeller systems with two to four coaxial rotors. The results show that in a two-rotor coaxial system, to lessen the adverse effects of a front rotor’s backwash and to operate at the maximum performance, only the back motor should be operated initially up to 75% duty cycle before using the front motor up to its 75% duty cycle. Additional thrust requirements should be generated from the back rotor and then from the front rotor up to their maximum duty cycles. In two, three, and four-rotor coaxial setups, total thrust output generated is 1.6, 2.1, and 2.5 times the thrust output at system thrust performance of 86%, 76%, and 66%, respectively of that of an isolated rotor. In a four-rotor coaxial setup, maximum system performance is achieved when the propeller pitch values are gradually increased from the first to the last rotor. The gradual increments in propeller pitch values also result in more uniform thrust sharing among rotors.

Spontaneity and its connections to mental health and wellbeing are a central issue in both theory and practice of psychodrama, and the specialized literature sometimes even associates the presence of pathology to a lack of spontaneity. This paper describes spontaneity in Moreno's theory, its assessment, its association with other measures and concepts, and scientific advances in the field. Specifically, we present results obtained with the English and Portuguese-language versions concerning its assessment. The main purpose of this work was to study the spontaneity measure (SAI-R) in a 3 first-order factors version for a Portuguese sample of 719 subjects, divided into two independent samples. The participants were aged 18 to 69. The mean age of participants was 28.5 years (SD = 7.51), and ages ranged between 18 and 69 years. Data was collected through an online platform of a Portuguese market research company. The results revealed that the 3-factor model has acceptable validity when items 1 (“Creative”) and 7 (“Euphoric”), confirming the composite reliability, the convergent validity, but not the discriminant validity. Through multigroup analysis, the model showed to be stable. Notwithstanding the need for complementary studies, including clinical samples, the SAI-R is a short and valid instrument in clinical and non-clinical contexts when evaluating spontaneity.
A Comprehensive Survey of Depth Completion Approaches

Depth maps produced by LiDAR based approaches are sparse. Even high-end LiDAR sensors produce highly sparse depth maps, which are also noisy around the object boundaries. Depth completion is the task of generating a dense depth map from a sparse depth map. While the traditional approaches focus on directly completing this sparsity from the sparse depth maps, modern techniques use RGB images as a guidance tool to resolve this problem. Whilst many others rely on affinity matrices for depth completion. Based on these approaches, we have sub-divided the literature into two major categories; traditional approaches and backbone-based approaches. The latter is further sub-divided into two-branch, and spatial propagation approaches. The two-branch approaches still have a sub-category named guided-kernel approaches. In this paper, for the first time ever we present a comprehensive survey of depth completion methods. We present a novel taxonomy of depth completion approaches, review and detail different state-of-the art techniques within each category for depth completion of LiDAR data, and provide quantitative results for the approaches on KITTI and NYUv2 depth completion benchmark datasets.

Published: May 2022

» Spinal osteotomies are powerful deformity correction techniques that may be associated with serious complications.

» The anatomical spinal osteotomy classification system proposes 6 grades of resection corresponding to different anatomic bone, disc, facet, and ligament interventions.

» Surgeons should be aware of the nuances of 3-column osteotomies with regard to spinal level selection, construct composition, and posterior column reconstruction and closure techniques.

» There is a global tendency toward avoiding 3-column osteotomies as much as possible because of the growing evidence regarding the effectiveness of posterior column osteotomies and halo-gravity traction.

Background:

Periprosthetic osteolysis is a known complication after shoulder arthroplasty that may lead to implant loosening and revision surgery. To date, there is no consensus in the shoulder arthroplasty literature regarding the definition of osteolysis or the grading criteria, thus making it difficult to quantify and compare outcomes involving this complication. The purpose of this study was to perform a systematic review of the literature to assess how periprosthetic osteolysis in shoulder arthroplasty is defined and evaluated radiographically.

Methods:

A systematic review of MEDLINE, Scopus, Cochrane, and CINAHL was performed in August 2021 for studies that provided a definition and/or grading criteria for osteolysis in shoulder arthroplasty. Only studies with a minimum of 2 years of radiographic follow-up were included.

Results:

Thirty-four articles met the inclusion criteria. After consolidating studies by the same primary author that included the same grading criteria, 29 studies were examined for their definition and grading criteria for osteolysis. Of these, 19 (65.5%) evaluated osteolysis surrounding the glenoid and 18 (62.1%) evaluated osteolysis surrounding the humerus. There was considerable heterogeneity in the systems used to grade periprosthetic osteolysis surrounding the glenoid, whereas humeral periprosthetic osteolysis was often categorized via visualization into binary or categorical groups (e.g., presence versus absence; mild, moderate, or severe; partial versus complete). Four studies (13.8%) provided novel measurements for assessing either glenoid or humeral osteolysis.

Conclusions:

Considerable heterogeneity exists in the assessment and grading of periprosthetic osteolysis in shoulder arthroplasty. The most common grading systems were binary and used qualitative visual interpretation, making them relatively subjective and prone to bias. Quantitative measurements of osteolysis were infrequently utilized. A standardized method of assessing osteolysis would be of value to facilitate communication and research efforts.
Airborne Trace Gas Remote Sensing and Surface Mobile In Situ: A Novel Tool for the Study of Structural Geological Controls from a Producing Oil Field

Accurate and representative determination of greenhouse gases (GHG) from oil and gas (O&G) production facilities requires high-spatial-resolution data, which can be acquired by airborne imaging spectrometers. However, assessment of nonmethane hydrocarbon emissions, which are far less amenable to remote sensing, requires mobile surface in-situ measurements (e.g., a mobile air quality laboratory).

Field in-situ measurements and airborne thermal infrared spectral imagery were acquired for three producing California oil fields (Poso Creek, Kern Front, and Kern River) located next to each other on 14 September 2018. In addition, a profile ascending a nearby mountain collected in-situ data for the Round Mountain oilfield. Plume methane to ethane ratios were consistent within different regions of the field and differed between these fields in a manner related to field geological structures.

Data acquired by an airborne thermal infrared imaging spectrometer, Mako, in 2015 and 2018 showed most emissions were from distant plumes in the Kern Front and Poso Creek fields. The spatial distribution of detected plumes was strongly related to faults, particularly active faults, which are proposed to stress infrastructure, leading to higher fugitive emissions and/or emissions from natural migration pathways (seepage). Additionally, the spatial distribution of detected plumes suggested unmapped faults. Thus, high-sensitivity imaging spectroscopy can improve understanding of reservoir geological structures that impact hydrocarbon migration and field operations, highlighting the potential for a novel reservoir management tool.
