Developing a Novel Approach for Integrating and Blending an Effective Emulsion Viscosity Model
Authors: Tebbani A. , Rodriguez D. J. , Morrison G. 
Published: February 2024

Abstract
This paper aims to develop a new, effective emulsion viscosity model by researching various correlations available from open literature. The approach is to blend and adjust these correlations to create a robust model that better characterizes oil-continuous and water-continuous liquid mixtures. The scope of the work includes integrating a phase inversion point calculation and defining a blending method to ensure a smooth and continuous transition between pure liquid phases when estimating effective liquid emulsion viscosity.
The technique involved blending and adjusting six correlations for emulsion viscosity, yielding the effective viscosity for oil or water continuous regimes. A calculated inversion point obtained from a published correlation was used to determine the transition between the two regimes. The new model was run in real-time while testing an inline Multiphase Flow Meter (MPFM) at Southwest Research Institute (SwRI) in May 2023.
Robust characterization of effective liquid viscosity in emulsion systems is crucial for reliable multiphase metering, as it directly impacts the calculation of liquid and gas rates via the effective Reynolds number (Re). The results of this study highlight the practicality and robustness of this new emulsion viscosity ensemble model. The observed improvement of gas and liquid rates compared to the reference emphasizes the practical impact of this model in enhancing MPFM measurement accuracy.

Abstract
Corrosion Inhibitor (CI) has been injected as corrosion mitigation supplementing corrosion allowance (CA) of Carbon Steel (CS) piping and pipelines at Mahakam since gas fields development in 1990's. By CI, the piping and pipeline integrity is expected reaching 20-30years design life. CI is considered effective not only by decreasing the CO2 or sweet corrosion likelihood. According to flow assurance study (FAS) focused on corrosion erosion as discussed in detailed by API RP 14E, CI presence increases the threshold of liquid erosional velocity. Disregard the possibility of CI absorption by sand, solid erosion is also managed by similar approach. Furthermore, thousands of CI injection package has been installed, monitored and maintained for decades with control valve limitation to set minimum injection rate as 2 liter/day. Considering production profile fluctuation, particularly when high amount of water and sand coming after plateau period, the CI forecast increase significantly, equal to the injection packages maintenance frequency and injection package problems. In 2020's, where reservoir depletion happened, the study to reevaluate the necessity of CI injection is initiated with objective to optimize (stop) CI injection at some flow lines thus preventing excessive CI consumption and process incompatibility issue without jeopardizing flow lines and pipeline integrity status. This paper summarizes the methodology up to getting &gt;50% cost optimization, which covering assessment of natural corrosion likelihood (NCL) as per empirical CO2 corrosion model and API RP 14E, actual corrosion likelihood (ACL) from corrosion coupon (CC) and remaining life assessment (RLA) and fitness for service (FFS) assessment on flow lines inspection result as per process piping design code ASME B31.3, piping inspection code API 570 and when necessary FFS assessment code API 579.

Abstract
Conventional wired communication technologies have taken a major role in industrial monitoring and control networks over the past years, they are becoming insufficient to fulfill the increasingly demands of today's plant modern applications, fundamentally due to the very complex design of wired infrastructure. Currently, Safety shower and eye wash stations at Shaybah Producing, GOSP#04 are not connected to DCS. The challenge is to connect them to DCS. However, the control room is far away and requires very long cabling, junctions’ boxes and including ground excavation costs for all locations. The proposed solution instead of conventional wired mechanical switches of safety shower and eye wash through cabling will be by a wireless shower/eye wash technology.
Wireless technology, yet, through its increased utilization, has the possibility to revolutionize the current industry to solve and mitigate existing problems faced by wired solutions. Nowadays, wireless technology has made a good step by introducing new class of applications, however, they still face hard utilization when specifically, real-time, reliable distributed control operations are concerned.
The current industry is becoming more complicated and consists of thousands of instruments, sensors, actuator and controllers, to carry over the required tasks and functions to be communicated to assigned control system. These systems, yet, have a massive amount of wiring that might increase the risk of failure for point to point communication data.
The proposed invention is related to wireless technology which is to implement a wireless shower monitoring system at a designated building having emergency eye wash/shower point of safety, this shall be achieved by deployment of proximity switches and discrete transmitters (DT). DTs transfer the eye wash shower status via wireless network to gateway that shall be installed in the control room roof top via multiple field link that are installed near to gateway. Gateway shall communicate shower eye wash status with existing DCS over Modbus TCP/IP communication. Therefore, shower status will be monitored through DCS.
Navigating Error Reduction: An Investigation of Enhanced Reality Technology and Operator Competency

Abstract
The baby boomer generation continues to retire and turnover in the process industry (the great resignation) is impacting many manufacturing sites with severe ‘brain drain’ at all levels, especially operators. The industry is searching for ways to make onboarding of new hires and plant specific qualification more efficient and effective. Traditional methods, like classroom training and shadowing experienced colleagues and SMEs for an extended period of time, are important but no longer sufficient.
Moreover, these traditional ways to pass on procedural knowledge tend to be highly dependent on the individual (people), which hinders standardization. Over time, shifts develop different ways of doing things, departing from the original procedure or taking shortcuts. In many instances, this leads to practice in the field not reflecting the written procedure. Our industry has a clear need for more transparency and a higher level of control over the practical procedural knowledge of the workforce (tribal knowledge), as well as a way to check and measure the level of operator knowledge and procedural compliance.
In addition to the shortcomings of traditional training, a common cause for practice in the field not reflecting the written procedures is that the ‘procedure clarity’ is often suboptimal due to the ambiguities or general statements in the procedure steps.
These challenges and shortcomings directly impact operational productivity due to long onboarding times and unplanned equipment downtime as a result of operating errors. They also directly impact plants’ safety performance, especially where actions cannot be automated and secured by safety instrumented systems. The flawless interaction of operators with the asset is an important layer of plant safety.
Enhanced Reality technology has been proven to solve the challenges described above. It allows simulating standard operating procedures in a photorealistic 3D environment (digital replica) for users to review, practice and test on standard operating procedures on-demand and on any device. Manufacturing organizations can capture their practical procedural expertise (Tribal Knowledge) and are able to measure and track procedure competency across their operators. This methodology has been labelled Digital Twin of the Person (DToP) by Gartner (1), referring to the human-centric approach of this technique.
Our presentation will include case studies from some of the process industries biggest companies that demonstrate the impact of improved procedure clarity and more consistent execution, which reduces unplanned events and speeds up operator onboarding while capturing more ‘tribal knowledge’.

Дослідження присвячене питанню неоколонізації Африки, з’ясуванню основних акторів та бенефіціарів, а також їх впливу на африканський регіон. Виокремлено два підходи, які використовують іноземні держави в процесі впливу на африканський регіон: безпеково-військовий та економічно-інвестиційний. Визначено, що існує певна кореляція між використанням військової сили й інвестиційною діяльністю в регіоні. Розглянуто вплив російських, британських, німецьких, французьких та американських приватних військових компаній на країни африканського регіону. Такі країни, як США і КНР, мають переваги в розрізі інвестицій та, гарантуючи безпеку урядів африканських держав, мають кілька військових баз у регіоні. Це обґрунтовано двома аспектами: слабкість урядів африканських держав та багатство регіону на природні ресурси. Натомість Франція через свою неспроможність ведення агресивної політики в африканському регіоні активно програє пропаганді та діяльності російських найманців. Лобіювання інтересів країн на майданчику ООН, як показує приклад голосування дружніх для росії країн, є доволі цінним ресурсом. Тому в цілому континент перетворюється на майданчик боротьби між заходом і сходом і доведено, що захід поступово програє цю битву за нову африканську колонізацію. Європа та США слабко бере участь у боротьбі за Африку, сподіваючись демократичними цінностями та інвестиціями в самозабезпечення країн Африки завоювати їх підтримку. Безпеково-військовий аспект розвитку українсько-африканських відносин є перспективним та може вирішити такі питання, як забезпечення працевлаштуванням ексвійськовослужбовців та забезпечення національних інтересів держави.

Authors: Wanda Indriya Pramesti  , Sudaryanto Wahyu Tri 
Published: February 2024

Background: Menstrual pain, or dysmenorrhoea, is common in young women worldwide under 25 years old. Elevated levels of prostaglandins in menstrual fluid induce contractions in the myometrium, leading to a decrease in uterine blood flow and resulting in uterine hypoxia. This hypoxia is the underlying cause of the painful cramping observed in primary dysmenorrhea. Massage is a non-pharmaceutical therapy that is hypothesized to be easily adoptable, with no side effects, and to have beneficial effects on pain. This study aimed to evaluate the effectiveness of effluerage massage in reducing menstrual pain in female students.
Subjects and Method: A randomized controlled trial was conducted at Junior High School 23 of Surakarta in July 2023. Total sample of 50 2nd grade female student was selected by purposive sampling and divided into two groups. Intervention group received effluerage massage and control group received usual care. The dependent variable was menstrual pain. The independent variable was effleurage massage. Menstrual pain was measured using Numeric Ranting Scale (NRS). Pain difference between groups after intervention was examined using independent t test.
Results: At the 6th follow-up period, the mean of menstrual pain score in the effleurage massage group (Mean 3.52; SD= 1.01) was significantly lower compared to the control group (Mean= 4.40; SD= 0.76), with a p-value of 0.001.
Conclusion: Effleurage massage is effective to reduce menstrual pain in Junior High School female students.
Keywords: effleurage massage, primary dysmenorrhea, menstrual pain, female adolescents
