Laktasyonu Artırmada Yeni Bir Yöntem: Hipnoemzirme
Authors: Tuncer Merve
Published: April 2024

Anne sütü bebeğin gelişimi için tüm gereksinimlerini karşılayan benzersiz bir besin kaynağıdır. Emzirme süreci doğal bir süreç olmasına rağmen özellikle ilk deneyimi olan anneler için bazı sorunları beraberinde getirebilir. Emzirme sürecinde yaşanılan sorunlar ise annenin psikolojik durumunu etkilemekte ve anne sütü üretimi ve salgılanmasını olumsuz etkilemektedir. Stres durumundan oldukça etkilenen oksitosin ve prolaktin hormonlarının baskılanması anne sütünün azalması olarak karşımıza çıkmaktadır. Bu nedenle emzirme sürecinde annelerin rahatlatılması ve endişelerinin giderilmesi çok önemlidir. Annelerin gevşemelerini sağlayarak oksitosin ve prolaktin hormonlarının salgılanmasını artıran yöntemlerden biri de hipnoemzirmedir. Hipnoemzirme, annelere emzirme sürecinin başarılı ilerlemesinde yardımcı olacak bir gevşeme ve olumlu telkin tekniğidir. Hipnoemzirme yöntemini inceleyen çalışmalarda, hipnoemzirme tekniğinin ilk 6 ay yalnızca anne sütü ile beslenme oranını ve anne sütü miktarını artırdığı belirlenmiştir. Bu derlemenin amacı laktasyon sürecini olumlu etkileyen yeni bir yöntem olan hipnoemzirme yönteminin incelenmesidir.

Amaç: Bu çalışmada pes planus düzeyinin dorsi ve plantar fleksör kas kuvveti ile gastroknemius ve hamstring kas esnekliğine etkilerinin incelenmesi amaçlanmıştır.
Yöntem: Çalışmaya alınan her bireyin yaş, boy, ağırlık, beden kütle indeksi gibi demografik özellikleri kaydedildi. Katılımcıların Pes Planus derecelerinin değerlendirilmesinde "Feiss Çizgisi" yöntemi, rijit veya esnek pes planus sınıflandırması için de "Jack’in Parmak Kaldırma Testi" kullanıldı. Hamstring kas kısalığı "Aktif Diz Ekstansiyon Testi" ile, Gastroknemius kas kısalığı "ayak bileği dorsi fleksiyonunun gonyometrik ölçümü" ile değerlendirildi. Dorsi ve plantar fleksiyon kas kuvveti "El Dinamometresi" kullanılarak ölçüldü.
Bulgular: Araştırmaya katılan 37 pes planuslu katılımcının (20 kadın, 17 erkek) yaş ortalaması 31,03±9,62 yıldı. Katılımcıların 35'i sağ dominant ekstremiteye sahipken, 2'si sol dominant ekstremiteye sahipti. Feiss Çizgisi yöntemine göre sol ayak için katılımcıların %48,6’sı 1. Derece (18 kişi), %32,4’ü 2. Derece (12 kişi) ve %13,5’i ise 3. Derece (5 kişi) pes planusa sahipken, %5,4'ünde pes planus (2 kişi) bulunmuyordu. Sol alt ekstremite için yapılan analizlere göre, ayak pes planus derecelerine ve esnek/rijit pes planus durumlarına göre; hamstring ve gastroknemius kas kısalığı ile dorsi ve plantar fleksör kas kuvveti değerlerinde istatistiksel olarak anlamlı bir fark bulunmamıştır (p>0,05). Sol alt ekstremitede Jack'in Parmak Kaldırma testine göre katılımcıların %73,0'ü esnek (27 kişi), %21,6’sı rijit (8 kişi) pes planusa sahipken, %5,4'ünde ise (2 kişi) pes planus deformitesi bulunmuyordu. Sağ ayak için yapılan analizde sol ayaktan farklı olarak esnek/rijit pes planus durumuna göre hamstring kas kısalığı değerlerinde anlamlı bir farklılık saptanmıştır (p<0,05). Bu sonuç, esnek pes planus durumuna göre, hamstring kas kısalığının rijit pes planus durumunda daha fazla olduğunu göstermektedir.
Sonuç: Çalışma sonuçlarına göre, sağ alt ekstremitede rijit pes planusa sahip bireylerin, esnek pes planusa sahip bireylere göre, hamstring kas kısalık düzeyleri anlamlı şekilde daha fazlaydı, fakat her iki alt ekstremitede de pes planus derecelerine göre kas kısalıkları ile kas kuvveti değerleri açısından anlamlı fark bulunmamıştır.

Published: April 2024

α-1-proteinaz inhibitörü (PI) olarak da bilinen α-1 antitripsin (AAT), dolaşımdaki en bol serin proteaz inhibitörüdür (serpin) ve serpin süper ailesinin prototipik üyesidir. AAT, tripsin yerine birincil olarak nötrofil elastazını (NE) inhibe eder. AAT kodlayan gen üzerinde de meydana gelen mutasyonlar sonucunda AAT eksikliği (AATD) meydana gelmektedir. AATD'li hastalar amfizem, Kronik obstrüktif akciğer hastalığı (KOAH), karaciğer yetmezliği ve daha az yaygın olarak sistemik anti-nötrofil sitoplazmik antikor (ANCA)-pozitif vaskülit ve nekrotizan pannikülite karşı hassastır. Tek nükleotid polimorfizmleri (TNP'ler), DNA metilasyonu, değiştirilmiş mikroRNA (miRNA) ekspresyonu ve SERPINA1 geni mRNA izoformları dahil olmak üzere çok sayıda epigenetik faktörün AATD'nin klinik görünümü üzerinde bilinen veya olası doğrudan etkileri vardır. Beslenme şekli epigenetik mekanizmaları etkilemektedir. Dolayısıyla AATD’ye bağlı gelişen solunum yolu ve karaciğer hastalıklarının progrozunu beslenme stratejileriyle değiştirmek mümkün olabilir.
Histamin İntoleransına Güncel Bakış
Authors: Öztekin Yeşim
Published: April 2024

Besin intoleransları, bazı besinlere veya bileşenlerine karşı immünolojik olmayan anormal organizma cevabıdır. Histamin intoleransı, histaminin metabolize edilememesi ve semptom yaratması ile gelişen besin intoleranslarından biridir. Diamin oksidaz (DAO) ve Histamin N metil transferaz (HNMT) enzimleri histamin metabolizmasında görev alan iki enzimdir. Çeşitli faktörlerin etkisiyle enzim üretimi veya aktivasyonlarının azalması ve histaminin parçalanamaması sonucu vücutta birikmesi ile histamin intoleransı patogenezinin geliştiği tahmin edilmektedir. Semptomlar arasında bireye göre değişmekle beraber abdominal distansiyon, karın ağrısı, kaşıntı, egzama, ürtiker, baş ağrısı, burun tıkanıklığı, rinit yer almaktadır. Özellikle sebebi bilinmeyen semptomlara sahip bireylerde DAO enzim aktivasyonun azaldığını gösteren çalışmalar mevcuttur. Farklı organları etkileyen semptomlarının olması, ayırıcı bir tanı testinin bulunmaması ve aynı histamin kaynağının farklı bireylerde farklı reaksiyonlara sebep olması histamin intoleransı tanısını zorlaştırmaktadır. Günümüzde tanı ve tedavi yaklaşımlarında histamin kısıtlı diyetler en güvenilir yöntem olarak kabul edilmektedir. Aynı semptomlarla seyredebilecek diğer hastalıkların varlığının dışlanması ve histamin kısıtlı diyete olumlu cevap, histamin intoleransı tanısını desteklemektedir. Tedavi, histamin eliminasyon diyetlerinin belirli bir süre uygulanmasını, histamin kaynaklarına beslenmede yeniden yer verilmesini ve semptomların takibini içerir. Bu derleme çalışmasında mevcut verilerle histaminin diyetsel kaynakları, metabolizması, histamin intoleransı ve ilişkili sağlık sorunları ile histamin eliminasyon diyetlerine yer verilmiştir. Besinlerde histaminin belirlenmesi ve histamin intoleransı, oldukça yeni bir kavram olduğundan, histamin intoleransı epidemiyolojisini belirlemek, tanı algoritmalarını ve olası tedavi seçeneklerini doğrulamak için daha fazla araştırmaya ihtiyaç vardır.

Authors: Üstündağ Yasemin , Yılmaz Osman , Kartal Mehmet
Published: April 2024

Aim: The aim of the study is to provide anatomical differences between rat and human scapula and definitive information to the literature about which strain is most appropriate for rat modeling, particularly in orthopedics.
Methods: In current study, a total of 40 scapulas belonging to Wistar Albino, Brown Norway, Sprague Dawley and Lewis strains were examined morphologically and morphometrically with each other and with the human scapula. Digital calipers were used to measure parameters for rat scapula. Literature searches were conducted for the measurements of the human scapula, and the obtained literature data was evaluated. A statistical analysis of the observed parameters was conducted using mean values, standard deviations, and One Way Anova Analysis in the IBM SPSS program. The Tukey post hoc test was used to determine the differences between groups that have a statistical difference. A fold ratio was calculated for each parameter based on the average values of all rat and human scapulae.
Results: According to One-Way Anova analysis, there is not any difference between groups for; width of collum scapula, length of cavitas glenoidalis-1, length of cavitas glenoidalis -2, width of cavitas glenoidalis, external width of cavitas glenoidalis, length of processus hamatus, width of processus hamatus, distance between processus coracoideus and incisura scapula, distance between cavitas glenoidalis to acromion at p<0.05 level. There is a statistical difference groups for; length of scapula (p<0.001), width of scapula (p<0.001), length of margo cranialis (p=0.001), length of margo caudalis (p<0.001), length of spina scapula (p<0.001), length of acromion (p=0.007), width of acromion (p=0.001), coracoacromial distance (p=0.003), distance between cavitas glenoidalis and incisura scapula (p<0.001), angle of angulus cranialis (p=0.001) levels.
Conclusions: Wistar Albino, Brown Norway, Sprague Dawley and Lewis rat strains are suitable for orthopedical animal models for especially models including cavitas glenoidalis. Any strain can be used in modeling indiscriminately. However, in modeling where the acromion, spina scapula, and edges of the scapula are important, the most appropriate strain specified in the current study should be selected.
How do the Working Conditions of a Healthcare Worker Affect Family Life?: Seeing Through the Eyes of Healthcare Worker Spouses
Authors: Kıskaç Neşe
Published: April 2024

Aim: In this study, it is aimed to evaluate the relationship between the working conditions of healthcare workers and their family life from the perspective of the spouses of healthcare workers.
Method: The research is a descriptive and cross-sectional study. The data of the study were collected from 146 physicians and nurse spouses in the form of an online questionnaire.
Results: It was determined that 68.5% of the participants were male, 69.9% of them were non-health personnel, 90.4% of them did not work shifts and the mean age was 41.79±7.74. It was determined that 74% of the health workers were nurses and 40.4% of them worked in internal clinics. The participants stated that they did not find their spouses' financial income sufficient (68.5%), they were generally unhappy when their spouses came home from work (75.3%), their sexual life was negatively affected (46.6%), and they sometimes felt nervous and tense because of their spouses' profession (52.1%). It was determined that there was a significant relationship between the clinics in which their spouses worked and their family and social lives being affected, allocating time for their children, their sexual lives being negatively affected, and being irritable, nervous and unhappy (p<0.05). It was observed that the clinics that negatively affected the aforementioned conditions were mostly internal clinics, operating theatres, intensive care units and emergency services.
Conclusion: As a result, the opinions of the spouses of healthcare workers show that there is a significant relationship between job satisfaction and the family life of healthcare workers. In the study, it was found that the family life of healthcare workers working in intensive care, operating theatre, emergency service units and internal clinics was more negatively affected than those working in other clinics. It is recommended to organise health policies that will increase the job satisfaction of health workers and to make rotations between clinics in a way that does not negatively affect the working environment.

Published: April 2024

With the advancement of technology, the effect of auxiliary machines used in rehabilitation is gradually increasing both in the evaluation stage and the rehabilitation stage of the treatment. The important feature of such devices is that they perform both assessment and treatment with the same device. At this stage, TecnoBody (Bergamo, Italy) devices play an active role in both assessment and rehabilitation. In this study, the effectiveness of TecnoBody devices, D-Wall, Walker View 3.0 SCX, and ProKin devices in rehabilitation was analyzed. It is reported in the literature that recently TecnoBody devices have been used significantly in evaluation, proprioceptive and stability tests have been performed with ProKin devices, and balance tests have been performed with the D-Wall device. The D-Wall device was found to be effective in therapies due to its use in rehabilitation, exergame, and biofeedback. It is observed that the Walker View 3.0 SCX device is effective in gait analysis evaluation and gait rehabilitation after surgery, while ProKin devices are effective primarily in proprioceptive, stability, and balance evaluations and then in balance and proprioceptive training. The use of TecnoBody devices in rehabilitation increases the active participation of people in therapy thanks to the visual biofeedback it applies to people, it is effective thanks to the fact that people can direct themselves during exercise and make therapy more fun with games. In addition, thanks to the personalized exercises in the D-Wall device, there are effective exercises to increase the participation of people in daily life activities, especially in neurological rehabilitation. Therefore, the use of TecnoBody devices in rehabilitation is effective.

“A Bloody Migrant Who Thinks He Can Run a Union”: The Case of Jerzy Bielski, a Migrant Trade Unionist in 1950s Australia
Authors: Nilsson Ebony , Persian Jayne
Published: April 2024

Jerzy Bielski, a Polish displaced person (DP) who resettled in Australia in 1949, was the first post-war migrant to work for an Australian trade union. He was recruited in 1951 by the Australian Workers Union (AWU) as a migrant unionist and, some years later, established his own migrant trade union: the New Citizens Council. The council faced heavy criticism from within the trade union movement, including by right-wing DPs who, acting as Cold War warriors, were instrumental in the Labor Party split in the mid-1950s. Ultimately, this article argues that migrant trade union activism has a longer post-war history than is commonly acknowledged.

The chemical composition of an extrasolar planet is fundamental to its formation, evolution, and habitability. In this study, we explore a new way to measure the chemical composition of the building blocks of extrasolar planets by measuring the gas composition of the disrupted planetesimals around white dwarf stars. As a first attempt, we used the photoionization code Cloudy to model the circumstellar gas emission around white dwarf Gaia J0611−6931 under some simplified assumptions. We found that most of the emission lines are saturated, and the line ratios approach the ratios of thermal emission; therefore, only lower limits to the number density can be derived. Silicon is the best-constrained element in the circumstellar gas, and we derived a lower limit of 1010.3 cm−3. In addition, we placed a lower limit on the total amount of gas to be 1.8 × 1019 g. Further study is needed to better constrain the parameters of the gas disk and connect it to other white dwarfs with circumstellar gas absorption.

The Draco Dwarf spheroidal (dSph) galaxy is one of the nearest and the most dark-matter-dominated satellites of the Milky Way. We obtained multiepoch near-infrared (NIR, JHK

time-series photometry for 212 RR Lyrae (173 fundamental-mode, 24 first-overtone, and 15 mixed-mode variables) and five Anomalous Cepheids in Draco dSph are presented and used to derive their period–luminosity relations at NIR wavelengths for the first-time. The small scatter of ∼0.05 mag in these empirical relations for RR Lyrae stars is consistent with those in globular clusters and suggests a very small metallicity spread, up to ∼0.2 dex, among these centrally located variables. Based on empirically calibrated NIR period–luminosity–metallicity relations for RR Lyrae in globular clusters, we determined a distance modulus to Draco dSph of μ
RRL = 19.557 ± 0.026 mag. The calibrated K

s
-band period–luminosity relations for Anomalous Cepheids in the Draco dSph and the Large Magellanic Cloud exhibit statistically consistent slopes but systematically different zero points, hinting at possible metallicity dependence of ∼ − 0.3 mag dex−1. Finally, the apparent magnitudes of the tip of the red-giant branch in I and J bands also agree well with their absolute calibrations with the adopted RR Lyrae distance to Draco. Our recommended ∼1.5% precise RR Lyrae distance, D
Draco = 81.55 ± 0.98(statistical) ± 1.17(systematic) kpc, is the most accurate and precise distance to Draco dSph galaxy.
Spontaneous thrombosis of type II vein of Galen aneurysmal malformation: a case report
Authors: Bogovski Stefan , Sirakova Kristina , Sirakov Stanimir
Published: April 2024

Vein of Galen malformations (VGAMs) are rare and complex congenital brain vascular anomalies that pose significant diagnostic and treatment challenges. The natural history of this type of vascular anomaly is very poor, with many patients succumbing to complications such as congestive heart failure, hydrocephalus, and brain parenchymal injury. Although the clinical course of most VGAMs was considered unfortunate, with meticulous imaging, a group of lesions with a more placid presentation and course can be identified.

We present a case of spontaneous thrombosis of VGAM where no embolization or surgical repair was attempted, with excellent clinical outcomes.

This case also highlights the possibility of spontaneous thrombosis in VGAM, even in the absence of clinical symptoms, and emphasizes the importance of a regular imaging follow-up in patients with known vascular malformations.
Intra-lake origin and rapid expansion of invasive pelagic three-spined stickleback in Lake Constance
Authors: Dahms Carolin , Roch Samuel , Elmer Kathryn R. , Ros Albert , Brinker Alexander , Jacobs Arne
Published: April 2024

The rapid expansion of three-spined stickleback (Gasterosteus aculeatus Linnaeus, 1758 (Perciformes, Gasterosteida)) in the pelagic zone of Lake Constance, Central Europe, since 2012 contributed to stark ecosystem-wide effects, such as food-web shifts and declines in native biodiversity, including commercially important fish species. Yet, the origin of this invasive pelagic population remains unclear. Using RAD-sequencing of Lake Constance sticklebacks, we show that the pelagic Lake Constance population likely arose recently within the lake, potentially from the littoral population. We did not detect any substantial genome-wide genetic differentiation between individuals from different habitats, supporting a recent origin of the pelagic population and/or ongoing gene flow. This is further supported by minimal differences in meristic and morphometric traits. However, we also identified multiple outlier loci between littoral and pelagic individuals across the genome, potentially suggesting early signs of adaptation despite high connectivity. In this study, we provide an important example of rapid within-lake ecological diversification of an invasive species from standing genetic variation. Ultimately, our findings will have major implications for the management of invasive pelagic stickleback, as they indicate that the stickleback population has to be managed as a whole and that management efforts cannot only focus on the hyper-abundant pelagic population.

Impatiens beipanjiangensis Jian Xu & H. F. Hu (Balsaminaceae), a new species of Impatiens subg. Clavicarpa discovered in Guizhou, China, is described and illustrated in this study along with its molecular phylogenetic analysis. I. beipanjiangensis is similar to I. liboensis, I. chishuiensis and I. clavigera in morphology, but I. tubulosa has the closest relationship to it. However, there are various ways in which the new species can be easily distinguished from these four species: Inferior nodes swollen rhizoid, pale green and with hooked outer sepals, longer lateral united petals, subovate auricle, deeper lower sepal and shorter spur that is reflexed towards the lower sepal. Furthermore, I. beipanjiangensis is distinguished from other Impatiens species, based on morphological, micromorphological and palynological evidence and molecular data (PP 0.967).

Published: April 2024

Angiopteris nodosipetiolata Ting Wang tris, H.F.Chen & Y.H.Yan, a new fern of Marattiaceae, is described and illustrated. Morphologically, A. nodosipetiolata is similar to A. chingii with more than one naked pulvinus on the stipe and numerous jointed hairs on the undersides of the mature pinnae. However, the pinnae of A. nodosipetiolata are lanceolate and can reach up to 4–6 pairs, whereas they are elliptic and occur in 2–3 pairs in A. chingii. Phylogenetic and genetic distance analysis, based on the plastid genomes, also indicates that A. nodosipetiolata is not closely related to A. chingii. Currently, there are ca. 500 mature individuals in Gulinqing Nature Reserve and we suggest A. nodosipetiolata should be categorised as an Endangered (EN) species according to the criteria of IUCN.

Published: April 2024

Fall detection (FD) for disabled persons in the Internet of Things (IoT) platform contains a combination of sensor technologies and data analytics for automatically identifying and responding to samples of falls. In this regard, IoT devices like wearable sensors or ambient sensors from the personal space role a vital play in always monitoring the user's movements. FD employs deep learning (DL) in an IoT platform using sensors, namely accelerometers or depth cameras, to capture data connected to human movements. DL approaches are frequently recurrent neural networks (RNNs) or convolutional neural networks (CNNs) that have been trained on various databases for recognizing patterns connected with falls. The trained methods are then executed on edge devices or cloud environments for real-time investigation of incoming sensor data. This method differentiates normal activities and potential falls, triggering alerts and reports to caregivers or emergency numbers once a fall is identified. We designed an Artificial Rabbit Optimizer with a DL-based FD and classification (ARODL-FDC) system from the IoT environment. The ARODL-FDC approach proposes to detect and categorize fall events to assist elderly people and disabled people. The ARODL-FDC technique comprises a four-stage process. Initially, the preprocessing of input data is performed by Gaussian filtering (GF). The ARODL-FDC technique applies the residual network (ResNet) model for feature extraction purposes. Besides, the ARO algorithm has been utilized for better hyperparameter choice of the ResNet algorithm. At the final stage, the full Elman Neural Network (FENN) model has been utilized for the classification and recognition of fall events. The experimental results of the ARODL-FDC technique can be tested on the fall dataset. The simulation results inferred that the ARODL-FDC technique reaches promising performance over compared models concerning various measures.
Topologically indistinguishable relations and separation axioms

Published: April 2024

This study focuses on defining separation axioms for sets without an inherent topological structure. By utilizing a mapping to relate such sets to a topological space, we first define a distinguishable relation over the universal set with respect to the neighborhood systems inspired by a topology of the co-domain set and elucidate its basic properties. To facilitate the way of discovering this distinguishable relation, we initiate a color technique for the equivalence classes inspired by a given topology. Also, we provide an algorithm to determine distinguishable members (or objects) under study. Then, we establish a framework for introducing separation properties within these structureless sets and examine their master characterizations. To better understand the obtained results and relationships, we display some illustrative instances.
Research Assessment Systems and the Effects of Publication Language: Manifestations in the Directory of Open Access Books
Authors: Snijder Ronald , Kingsley Danny
Published: April 2024

Research assessment is a major driver of research behavior. The current emphasis on journal citations in a limited number of journals with an English focus has multiple effects. The need to publish in English even when it is not the local language affects the type of research undertaken and further consolidates the Global North-centric view or scientific approach. The bibliometric databases on which assessments of universities and journals are based are owned by two large corporate organizations, and this concentration of the market has in turn concentrated the research environment. Open infrastructure offers an alternative option for the research endeavor. The OAPEN online open access library and the Directory of Open Access Books form part of this infrastructure and we consider the pattern of languages present in the directories over time.
La gouvernance : étude d’un échantillon de 22 entreprises en Guyane française
Authors: Chim Paul Roselé
Published: April 2024

La gouvernance joue un rôle essentiel dans le fonctionnement et l’amélioration de la performance des entreprises en définissant proprement leur structuration pour s’adapter aux changements de l’environnement économique. Penser que toutes les sociétés pourraient appliquer des règles de gouvernance identiques serait perturbant, voire déstabilisant pour un système qui est par ailleurs globalement doué à rechercher toujours plus de cohérence et d’efficacité. Dans les discussions sur la gouvernance et la performance, le dirigeant occupe une place majeure dans le processus conduisant à la création des richesses. Ce papier se focalise à étudier la gouvernance d’entreprise à travers un échantillon de 22 entreprises de taille assez variée qui recouvre l’ensemble de l’économie de la Guyane française.
L’effectivité des lois sur la sortie de l’indivision successorale en Outre-mer atlantique
Authors: Phrakhaythong Vinaly , Duro Karyne Larifla
Published: April 2024

40 % du foncier serait encore paralysé par des indivisions successorales en Guadeloupe ou en Martinique. Cette problématique n’est pas propre aux Antilles, elle se retrouve aussi dans d’autres territoires ou collectivités d’Outre-mer (la Réunion, Mayotte…), mais aussi la Corse. Ainsi, ces dernières années, les régions ultra-marines ont bénéficié d’une inflation législative ayant pour finalité de sortir de ces indivisions complexes. Plusieurs dispositions transitoires spécifiques aux Outre-mer ont été adoptées. Ensuite, la loi dite « Letchimy » du 27 décembre 2018 s’est donné pour objectif de lutter contre les situations d’indivision inextricables et relancer la politique du logement. Elle vise à faciliter la sortie des indivisions successorales de plus de 10 ans en Outre-mer. Il s’agit d’un dispositif expérimental pour une période de dix ans qui permet au notaire de partager les biens dès lors qu’une majorité simple des indivisaires est atteinte au lieu de l’unanimité requise en droit commun. Cependant, les notaires qui sont les chevilles ouvrières du dispositif font montre de nombreuses réticences. Comment l’expliquer ? L’effectivité de ces lois est pourtant une question sensible dans la mesure où elle permet d’apprécier, d’évaluer la portée de ce mouvement législatif. Il convient dès lors de comprendre ce qui fait obstacle à la mise en application du dispositif afin de tenter de trouver des solutions pour débloquer ces situations.
President's Speech and Terminology Used During the COVID-19 Pandemic
Authors: Theledi Kgomotso , Pule Violet M. S
Published: April 2024

This chapter investigates the interpretation of the South African President's terminologies during family meetings in a linguistic and situational context. During the COVID-19 pandemic, South African President Cyril Ramaphosa addressed the nation to communicate important information and updates about the virus and the measures taken by the government to curb the spread of the virus. The authors argue that most South African people do not know how to write and speak English; however, the information was delivered through the medium of English, excluding those who do not know the English language, with special reference to Setswana speakers. Hence, the chapter focuses on the South African President's speeches during the COVID-19 pandemic era. A theory of Afrocentricity will be employed in a qualitative approach to address the research questions and objectives of this chapter. At the end of this chapter, communication strategies are addressed in line with language use and cultural appropriateness.

The intelligent well completion in Brazilian Pre-salt wells poses challenges for workover operations. This paper describes the main challenges faced and the new methods employed for workover in this scenario. Since acid stimulation caused severe fluid losses in these wells, which are equipped with integral intelligent completion [1 – SPE-195935], the removal of the production string brings several complications. Through tubing operations, such as the use of nippleless plug set, feedthrough packer release, and mechanical cutting of the production string, were conducted. The removal of the completion string was done in a single trip, with fluid losses sustained and well safety concerns considered. The use of Managed Pressure Drilling (MPD) techniques was employed and required modifications to existing tools. A thorough planning for the new completions was developed to safely return the well to production. The successful application of these techniques in a workover operation in 2023 demonstrated its suitability for high complexity and high productivity wells, such as those found in the Brazilian Pre-salt, potentially benefiting the entire industry.
Monitoring Subsea CCS: Following the CO2Molecules From Top to Bottom and Ensuring They Stay in the Rock
Authors: Wiltshire M. , Roux P.
Published: April 2024

This paper evaluates technologies and available methods for the surveillance of flow in subsea CO2 injection systems, going from the subsea infrastructure to the injection wells, into the reservoir, and then back to the seafloor. Considerations and provisions required in the subsea system to accommodate certain surveillance technologies are highlighted. In this paper, the potential path taken by CO2 molecules are followed through a subsea storage system, with leak detection and plume surveillance in mind.

Feasibility and opportunities for using monitoring methods and leak detection technologies were assessed by utilizing an assessment matrix which summarises the various advantages and disadvantages of plume monitoring technologies and leak detection methods. The following aspects were assessed for each technology: 1. Technical feasibility; 2. Technology Readiness Level (TRL) and development required; 3. Impact of the solution on the subsea system (e.g. field architecture, power and communication); 4. Relative costs; 5. Schedule (e.g. added risk due to development required).

Leak detection methods having unknown efficacy and limited research in CO2 applications were screened out. Those methods which have been field tested for CO2 service or currently under lab testing were advanced to a second stage of screening by product specifications to further consider their integration into the subsea injection system design. Passive acoustic technology was found to be the best suited for detection across subsea infrastructure as it covers a desirable detection radius at the lowest cost. Screening of plume monitoring methods showed benefits and drawbacks of each method evaluated; the review concluded that different technologies should be used at different stages of a subsea CCS project. Near well bore, CO2 migration monitoring can be performed using Vertical Seismic Profiling (VSP) as it yields a high-resolution image in the vicinity of the well. When the plume eventually outgrows VSP's radius of investigation, a sparse acquisition strategy can later be used to verify conformance of reservoir model's plume migration at strategic locations. Finally, leak detection tools such as an AUV with side scan sonar and a chemically degraded trigger and beacon could be used for leakage from the reservoir through the seabed and legacy wells respectively.

This paper provides a novel integrated view of CO2 escape paths, bringing together topics around CO2 leak detection from subsea injection equipment, sub-surface plume monitoring and leakage from reservoir through the seabed. The results of this research can benefit CCS projects in the concept phase influencing the design of subsea infrastructure to accommodate monitoring methods, thus guiding technology and risk assessments to support a Measurement, Monitoring and Verification (MMV) plan.

Decommissioning decision-making is an integral and complex process in various industries, such as nuclear power plants, oil and gas facilities, and industrial manufacturing plants. The planned service life of many offshore oil and gas facilities is coming to an end. Decommissioning these facilities has emerged as a crucial task due to significant and uncertain expenses, high operational risks, potential social consequences, and environmental considerations related to the marine ecosystem. This paper proposes an evolving methodology to assist a sustainably oriented decision process for decommissioning the subsea infrastructure of offshore oil and gas facilities.

Decision-making plays a crucial role in the search for a balance between the concerns of stakeholders, such as oil and gas companies, government bodies, environmental protection organizations, marine and coastal environmental users, and local communities. The decision problem is often complex since, most of the time, no ideal option is available to satisfy all criteria. Decision-makers can employ advanced approaches to address this problem, such as the multi-criterion decision analysis presented in this work. This methodology improves the decision-making process by ranking the various options for decommissioning subsea oil and gas assets. The model considers six criteria: Safety, Environment, Waste Management, Technical, Social, and Economic. Multiple decommissioning alternatives are compared, where groups of structures with similar technical and environmental characteristics are identified and analyzed together.

The paper summarizes the application of this methodology in decommissioning different fields off the Brazilian coast, demonstrating excellent performance in helping the decision-making process.

The methodology proposed addresses the growing concern about properly disposing of the decommissioned materials in an environmentally responsible manner with guidance from life-cycle assessment methods. Furthermore, attention is given to sustainability-related concerns regarding emissions generated during decommissioning operations. A set of tools was developed to help the stakeholders to have a better understanding of the results. The methodology contributes to reducing the subjectivity of the decision by assisting a project that is still conceptual to make decisions based on solid foundations raised through various databases and specialist knowledge.

TotalEnergies is committed to the goal of sustainability as it targets to achieve NetZero by 2050. One of the levers to carbon intensity reduction is to reduce direct emission from our portfolio and developing carbon sinks. Hence, the plan is to provide carbon storage services which would store equivalent of 50-100Mt/year of CO2 (TotalEnergies, 2023). To realize this objective, the logical step is by building capacity, in terms of skills and projects, to adapt to the new requirements of CO2 injection.

This ambition requires developing viable and sustainable surface and downhole equipment design which can meet the challenges of CO2 injection. Our focus is the case of CO2 that is transported in dense phase to the well and then injected into a highly depleted reservoir. Among the challenges associated with the dense phase CO2 injection into a depleted reservoir is the question of compatible completion strings, tubing connections and Downhole Safety Valve (DHSV); which form the primary well barrier, capable of handling potentially extreme low temperatures and rapid swings of temperatures associated with transient conditions of CO2.

Thus far, we have proposed credible load cases for completions stress analysis and developed a methodology / guideline for completions design in highly depleted reservoir. Today, we routinely apply it to every project in focus; to incorporate CO2 sequestration in the project development plans.

The results of this methodology clarify the specific need(s) for completions design and associated equipment qualifications for CCS applications in highly depleted reservoir environment.
Prospects for Marine Minerals in the US Pacific OCS and EEZ
Authors: McConnell D. R.
Published: April 2024

The seafloor in the US Pacific OCS and EEZ is enriched to varying degrees in critical and economically important minerals such as nickel, manganese, cobalt, copper, zinc, REY (rare earth elements plus yttrium), titanium, vanadium, antimony, gold, and silver. These mineral deposits take the form of polymetallic nodules on the seabed, cobalt rich ferromanganese crusts on seamounts and ridges swept clean of sediment accumulation, and seafloor massive sulfides formed by hydrothermal systems at geologic plate spreading centers and volcanic margins. Each of these mineral deposits form on or near the deep ocean seafloor where water depths are typically 4000 m to 5500 m and on the seamounts and volcanic arcs that rise from these depths. Commercial interest in deep sea mineral deposits and the potential for collecting or mining them began in earnest in the 1970s but has been heightened in the last 20 years as the international framework for developing these minerals in International Waters has matured that has coincided with forecasted rapid rising demand for minerals to supply energy and manufacturing needs for the green economy. Compilation reports published by academia, government, and private companies are reviewed to assemble data and assess the prospects for deep sea marine minerals in the US Pacific OCS and EEZ. Key compilations were made by the Circum-Pacific Council and USGS in the 1980s and 1990s. These, together with recent (2023) efforts by USGS to compile geochemical data from USGS affiliated marine research sampling cruises from the 1980s and 1990s, historical data maintained by NOAA National Centers for Environmental Information (NCEI), and recent publicly disclosed results from ISA contractors are used to inform the known occurrence and prospectivity for polymetallic nodules, cobalt-rich ferromanganese crusts, and seafloor massive sulfides in the US Pacific OCS and EEZ.
