A randomized prospective comparative study to evaluate the efficacy of prostaglandin E2 (Dinoprostone) controlled release vaginal insert versus sublingual prostaglandin E1(Misoprostol) in induction of labor in term gestation
Authors: Sahu Rakhee , Janjewal Kirti 
Published: November 2021

In modern obstetrics, one of the common challenges is induction of labour (IOL). WHO Global Survey reported that IOL accounted for 9.6% of all deliveries. Prostaglandins have evolved and frequently used pharmacologic agents for IOL, owing to their dual action of cervical ripening and uterine contraction inducing effect. : 1. To compare the efficacy and induction to delivery interval (IDI) of PGE2 vaginal insert and Sublingual PGE1 in induction of labor in term pregnant women; 2. To study the maternal and fetal outcome in both groups.: This a randomized, prospective, comparative study of 100 term pregnant women for induction of labour. Group 1-(50 women) PGE2-10mg vaginal insert and group 2-(50 women) PE1 Sublingual tablets – maximum 200 mcg in 24 hrs, at Dr LH Hiranandani Hospital, Mumbai, India.: In my study the mean induction to delivery interval in Dinoprostone group was 17.47 hours and 23.44 hours in Misoprostol group. So the mean IDI was shorter in Dinoprostone insert group than Misoprostol group by about 6 hours. There was no significant difference noted in terms of overall incidence of caesarean deliveries among the groups. Our study concluded that Dinoprostone 10mg vaginal insert was more efficacious than sublingual Misoprostol in reducing induction to delivery interval without maternal and fetal complications.Our study suggests that the Dinoprostone vaginal insert can be used as both inducing as well as augmentating agent in labour. Dinoprostone vaginal insert maybe more effective in reducing the incidence of caesarean sections.

Authors: Gowthami M R Shruthi 
Published: November 2021

Allergic rhinitis (AR) is one of the most common disease in India. The association between eosinophils and allergic diseases has been known since many years. To correlate Nasal smear eosinophilia (NSE), blood absolute eosinophil count (AEC) and total serum IgE levels with severity of the clinical score in patients with allergic rhinitis. This is one-year prospective study in patients (n=60) presented with allergic rhinitis to our institute. After taking consent, all the study participants were subjected for blood AEC, IgE levels and nasal smears for eosinophils. Among the samples, 81.7% were males. The mean age of patients was 35.2 years. AEC &#62; 440 cells/cu.mm was seen in 46.6%, NSE&#62;10% in 81.6% and total serum IgE was elevated &#62; 100 IU/ml in 95.0%. There was a good correlation of NSE and serum IgE with the severity of disease. There was no correlation of blood AEC with the severity of clinical score. Data was analysed using SPSS software.rn NSE and IgE both correlated well with severity of the disease. Nasal smear cytology is a simple procedure having good correlation with severity of clinical score should be used routinely. Testing for serum IgE levels will increase the accuracy with a better diagnostic utility.
A mixed methods contribution analysis of UK students’ unions’ internal communications response to addressing staff motivation during the Covid-19 pandemic
Authors: Kitching Matthew 
Published: November 2021

This macro-level, mixed methods contribution analysis evaluates the influence of students’ unions internal communication response to the Covid-19 pandemic on staff motivation. Recognising the role individual interpretation and perception play in the receipt of such messages, this paper seeks to understand which motivating factors union managers sought to address through their communications, whether these efforts were recognised by staff and whether there is evidence they may have helped to alleviate employee concerns. The evaluation findings will be of interest to student union managers and professionals looking to enhance communications and improve employee motivation.

The e-portfolio in higher education: The case of a line of teaching innovation and complex change management
Authors: Berbegal Vázquez Alfredo , Merino Orozco Abel , Arraiz Pérez Ana , Sabirón Sierra Fernando 
Published: November 2021

This work proposes a line of innovation to implement possible uses for the e-portfolio in higher education. We present an initial framework for analysis with attention to three main arguments: the validity of the interest of the e-portfolio for higher education in light of the current challenges posed by the knowledge society; the relevance of complex change management within organisations such as universities; and the identification of critical elements in the relevant literature concerning experiences similar to the case analysed here. The milestones for the line of innovation include six projects and three teacher training courses. Once data had been gathered in the respective assessment phases for each milestone by means of document analysis techniques (e-portfolios, teaching materials, usage statistics), questionnaires, discussion groups, in-depth interviews, and self-assessments (responsible academics, teachers, and students), a global analysis of the whole line was conducted from a complex approach to the problems of teaching change and innovation. A technological, political and cultural reading of innovation reveals emerging problems to reconsider: the attainment of deep learning; the standardisation of academic tutoring; the formation of learning and practice communities; the reconceptualisation of the e-portfolio as a personal learning environment; and the transformation of the university institution as a learning organisation. The premature condition of higher education to deal with the change in the teaching paradigm and the urgency to revisit its innovation policies to overcome it stand out among the critical conclusions of this study.

Geohistorical, didactic, and linguistic competencies learning through a bilingual (Spanish/English) fieldtrip project with teachers in training
Authors: Martínez-Hernández Carlos , Albaladejo-Albaladejo Sara 
Published: November 2021

This research is predicated on the hypothesis that a fieldtrip project adhering to a CLIL (Content and Language Integrated Learning) philosophy can be effective in promoting learning of both social and linguistic competencies. The main objective was to evaluate the didactic efficacy of a bilingual urban itinerary with teachers in training (from bilingual and non-bilingual groups) to develop geohistorical, didactic and linguistic competencies. Procedural and consolidated learning was assessed, via a dossier of activities and a statistically validated pretest-posttest. High development values were obtained in procedural tasks (average = 8.8/10), as well as a high increase in consolidated acquisition (average = +24.5% students). The greatest growth was observed in language skills (+ 26.4%). The assessed knowledge after the itinerary was significantly higher than before, for all competencies. However, there was no statistically significant difference between students belonging to bilingual or monolingual groups. Students positively valued these results. It is concluded that a local didactic fieldtrip is an effective CLIL strategy to develop social and linguistic competencies, and yet it is rarely discussed in the scientific literature and curricula.

Geochemistry of the Organic Matter of Ulug-Khem Basin Coals
Authors: Bushnev D.A. , Ondar S.A. , Burdel’naya N.S. 
Published: November 2021

Abstract
—The composition of the organic matter (OM) of coals of the Ulug-Khem Basin has been studied. According to Rock-Eval pyrolysis data, this OM is a type III kerogen, sometimes significantly oxidized. The coal of low-grade metamorphism has a high hydrocarbon potential. Based on the gas–liquid chromatography and chromatography–mass spectrometry data on the distribution of n-alkanes, isoprenoids, polycyclic biomarkers, and aromatic hydrocarbons, we have established the composition of the primary OM of the coals and the grade of OM metamorphism. The primary OM of the coals consists mainly of remains of aquatic vegetation and terrigenous OM. The latter includes conifer remains, which are identified from the presence of 4β(H)-19-norisopimarane in the aliphatic fraction of bitumen and from the domination of retene over cadalene and 6-isopropyl-1-isohexyl-2-methylnaphthalene in the aromatic fraction.
Trilobites, Biostratigraphy, and Geochemistry of the Middle Cambrian Kuonamka Formation (Northeastern Siberian Platform, Kyulenke River)
Authors: Korovnikov I.V. , Parfenova T.M. 
Published: November 2021

Abstract
—We studied the middle Cambrian unit of the Kuonamka Formation section on the Kyulenke River (Siberian Platform) and performed its biostratigraphic subdivision based on trilobites. The middle Cambrian section has intervals corresponding to the regional zones of the Amginian Stage. Six levels with mass accumulation of fauna remains have been identified: Two levels are located within the Ovatoryctocara Zone; the third level is at the boundary between the Ovatoryctocara and Kounamkites zones; the fourth layer is confined to the roof of the Triplagnostus gibbus Zone; and the fifth and sixth levels are located within the Tomagnostus fissus–Paradoxides sacheri Zone. The composition of rocks and bitumens of their organic matter (OM) has been studied, including the geochemical specifics of the mineral components of rocks (iron, sulfur, and CO2) and of saturated hydrocarbons of bitumens as well as noncarbonate carbon isotopes in the OM. It has been established that the OM sedimentation took place under normal aeration of the sea basin waters, without hydrogen sulfide contamination of the bottom waters. The intensity of chemical and biochemical transformations of mineral and organic components during diagenesis was controlled by the contents of organic carbon and sulfate ion, the activity of the anaerobic prokaryote community, and the rate of sediment mineralization. We have also established relationships between the content of organic carbon in potentially oil source rocks and the contents of iron oxide, total sulfur, and sulfide and sulfate sulfur as well as the ratios of saturated hydrocarbons. The alternation of highly carbonaceous black shales and carbonaceous rocks is apparently due to a change in the composition of biologic communities of microorganisms (sources of hydrocarbon biomarkers) and in the intensity of OM transformation during diagenesis. We assume that the OM transformation included sulfate reduction and dealkylation of high-molecular steroids in the unconsolidated OM-enriched marine sediments with the participation of bacteria. The intensity of these processes depended on the mass of the primary OM, the amount of sulfate ion, and, hence, the pH and Eh of the medium.

Published: November 2021

Abstract
In a continuous effort to reduce cost and improve efficiency, the Oil and Gas industry has been trying for the last 10 years to develop methods to perform subsea Coiled Tubing (CT) operations from a vessel and without a riser.
In September 2020 a large campaign of Riserless Coiled Tubing (RLCT) coring was successfully executed in the Norwegian Sea, on the Mohns Ridge, approximately 330 nautical miles from the coast.
The campaign was performed from a small Anchor Handler Tug Supply vessel, the Island Valiant.
A total of 14 open water gravity-fed RLCT runs were executed in water depths between 2780 and 3085 m.
The system performed extremely well and proved to be very robust, efficient and effective for these innovative operations. This was the first time that RLCT coring operations were completed without the use of a subsea injector, in the so-called gravity-fed mode, and in such ultra-deep water.
This paper describes the project in detail, including the system setup used, a summary of the operations and the actual results achieved, before discussing future improvements and applications of the RLCT technology.
Synchronized Service Delivers Desired Outcomes
Authors: Morris David , Atkinson Malcolm , Avery Mike , Gillespie David 
Published: November 2021

Abstract
As the subsea well intervention sector ascends from a double-dip downturn, operators are motivated to execute projects with increased agility. By adopting new rationale and supported by strategic partnerships, an enhanced focus on operating efficiency is targeted.
This paper discusses how operators can
– deliver predictable operational expenditure (opex) results, safeguarding life-of-field economics through routine interventions and robust risk mitigation – align objectives with service providers through technology, strategy, and process – realize value of integrated alliances in the subsea intervention sector.
Reliability is the cornerstone on which operational integrity is established. Repeatability is the foundation on which partnerships are formed, forging a synchronized philosophy; pledging operational efficiency as commanded in a dynamic environment; bringing to market a holistic, multileveled, multiskilled solution to subsea interventions; and uniting product and operational experts to evaluate the range of scope requirements selecting fit-for-purpose solutions, delivered with synchronized processes.
Here we describe how this approach, coupled with repeatable field-proven product and service reliability and driven by true customer-centric thinking, minimizes operating risk to deliver predictable outcomes.
This ethos is demonstrated in action via three case studies that discuss the benefits of combining customer expertise with product and operational specialists during the initiation and planning phases of subsea well intervention projects.
The shared examples demonstrate how inculcating a continuous improvement mindset and applying lessons learned to product design, process, and procedures can drive operating efficiency to new levels.
Campaigns executed in 2020 by the supplier delivered best-in-class results, exceeding customer expectations. The campaign represented the first fully synchronized service operation on the Q5000 intervention vessel at 90% operating efficiency. In addition, they demonstrated outstanding versatility by outperforming budget on the first deployment of the 15,000 psi intervention riser system (IRS) from the Q4000 intervention vessel. Less than 1% operating nonproductive time (NPT) was attributed to the well access package for the campaign.
Sustaining this level of success via collaborative performance management is the next step on the roadmap to ensure this becomes the new normal. Conclusions drawn from customer feedback indicated expectations were surpassed, and that synchronicity is the key that unlocks the door to sustainability in the subsea deepwater intervention sector.
Thermal Wellbore Failure Detection Case Studies: A High Temperature Multi-Finger Caliper Surveillance Approach
Authors: Khastoo Reza , Mostafa Sameer , Fraser Alastair 
Published: November 2021

Abstract
Cooling of thermal wellbores such as steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS) wells, is a common prerequistite to allow deployment of logging instruments due to the temperature limitation of imaging instruments’ electronics (&lt;150°C). This paper presents a memory caliper technology housed in a thermoshield that can perform at up to 220°C, with the acquired data used to evaluate the integrity of tubulars and completion items (metal loss, deposition, deformation, and gap/hole damage), negating the need for cooling before deployment.
Two cases are presented. One is a SAGD well with liner screens across the lateral section. The memory multi-finger caliper was deployed using coiled tubing and the data were successfully obtained across the lateral section with a maximum recorded temperature of 169°C. The second example is a vertical well in a steam flood field. Because of the uncertainty over the downhole temperature at the time of the well intervention, a temperature sensor was deployed in surface read-out mode above the caliper. This ensured the 220° temperature limit of the caliper would not be breached, and a maximum temperature of 208°C was recorded.
The data confirm the feasibility of acquiring high accuracy/high resolution data from thermal wellbores without having to resort to manipulative cooling techniques to attain a temperature below 150°C. Enlargement of a limited entry perforation (LEP) was observed in the horizontal well and buckling was clearly detected in the vertical well. The broad measurement range of the caliper – 1.85" – 7.2" – enabled both the tubing and liner to be logged in a single well intervention, which facilitated a swift resumption of of steam injection activities. Ultimately, the high temperature MFC's ability to minimize deliberate cooling the thermal wellsbore before deployment, has time and cost saving implications throughout the life cycle of the well.
Much of the existing literature examining downhole data acquistion in thermal wells, for the diagnosis of wellbore integrity issues, has relied on technologies that are unable to withstand temperatures much greater than 150°C. The ability to execute well interventions for data acquistion at higher temperatures offers the potential for empirical studies that compare the status and integrity of the wellbore completion in thermal and cooled conditions.
Enabling and Shaping Decommissioning Alternatives in Malaysia

Published: November 2021

Abstract
This paper is to demonstrate the significance of structured planning, holistic assessment and synergies, as key value drivers in enabling and shaping decommissioning alternatives leading to sustainable decommissioning and circular economy.
PETRONAS as the regulator of Malaysia's Upstream activities manage decommissioning obligations through Production Sharing Contracts, internal guidelines and other relevant procedures and standards. The Decommissioning Options Assessment (DOA) is the process used to land on the most feasible option.
Throughout PETRONAS’ 18-year decommissioning journey thus far, decommissioning projects were successfully executed using various alternatives. The valuable learnings gained are applied to further strengthen our decommissioning processes in regulating, enabling and shaping future executions at the lowest cost with safety of life and protection of the environment as our utmost priority.
Upon a decision to proceed with decommissioning, a gated technical review process is used as the governing process to ensure safety, protection to the environment and cost efficiency. It is during this gated technical review that DOA is conducted. The output from the DOA is deliberated within the ambit of five (5) key criteria, i.e. Health, Safety & Security, Environment, Society, Technical & Operational, and Economy. Upon completion of execution, lessons learnt coupled with findings from post-decommissioning surveys are analyzed and applied to future projects.
Synergies and collaborations are key drivers in shaping sustainable and replicable alternative decommissioning solutions. PETRONAS continuously pursues strategic collaborations with all stakeholders, including but not limited to, government ministries/agencies, academia, and industry players to tap into global decommissioning solutions, scientific researches, technologies, and best practices. This key lever will be discussed in the paper.
From actual experiences, supported by studies, it is evident that decommissioning alternatives, including Rigs-to-Reef, add value in terms of marine habitat protection, biodiversity enhancement, fish aggregation, etc. It has also contributed positively to the livelihoods and well-being of society. Re-using platforms for new field development maximizes value by extending the platform's useful life. In addition, PETRONAS also advocates the ‘design for decommissioning’ mindset during a field's development phase in achieving a robust life cycle cost. PETRONAS further believes the values gained from these decommissioning alternatives will contribute to the decommissioning ecosystem in Malaysia.
Moving forward, PETRONAS aspires to elevate the sustainable decommissioning model with the mindset that, ‘no single piece of an abandoned structure goes to waste’. There is a need to mature studies, collaborations and supply chain readiness in realizing more options on the 3Rs (Reduce, Re-use and Recycle).
Pipeline Decommissioning: Comparative Study of Pipeline Corrosion in the North Sea and the Gulf of Thailand
Authors: Campins Bravo Jose 
Published: November 2021

AbstractThe long-term degradation of decommissioned pipelines left in situ is an important topic in decommissioning projects. These constitute a long-term health and safety challenge in the form of snagging risk to other users of the sea. An accurate forecast of the long-term behavior of the pipelines in the marine environment would allow to make an informed decision regarding the feasibility of leave in place option for pipeline decommissioning.This paper aims to summarize the effect that individual environmental factors in marine corrosion have on the corrosion rate and to discuss in detail a chosen corrosion model that could be used to predict the long-term corrosion of in situ decommissioned subsea carbon steel pipelines in the marine environment.In addition, the long-term degradation will be predicted with the chosen corrosion model and the results will be compared for a range of subsea pipelines to be decommissioned in the North Sea and the Gulf of Thailand. With the chosen corrosion loss model, considering the higher average annual seabed temperature in the Gulf of Thailand in comparison with the North Sea, the predicted long-term corrosion rate of unprotected carbon steel is 0.053 mm/y for the North Sea and 0.069 mm/y for the Gulf of Thailand.
