Published: February 2025

During the pandemic, law enforcement was carried out online in many courts around the world, including the Indonesian courts. The implementation of this online trial involves law enforcement as the party conducting the online trial. There are many challenges faced related to how online trials are managed, changing law enforcement procedures, including how technology is used in trials by law enforcers to support trials, however online trials are still implemented through the support of communication processes. This research aims to describe the transformation process carried out by law enforcers during the implementation of online trial communication. The concepts used are trial transformation, communication and diffusion of innovation. This research was conducted qualitatively using a phenomenological approach, the researcher conducted interviews with 7 informants consisting of 2 judges, 3 prosecutors and 2 legal advisors, the researcher also conducted analysis on archived online trial recording documents. The results of this research show that online trials are carried out as an implication of physical and social restriction policies, as well as a form of developing online-based trial services. The transformation process carried out by law enforcers during the implementation of online trial communication is carried out using two transformation models, namely the personal transformation model and the institutional transformation model. Success in implementing online trials as a form of transformation is influenced by the quality of infrastructure, law enforcement literacy, communication established between parties, namely communication between institutions, including the court, prosecutor's office, police, and law offices.

Published: February 2025

The Baduy indigenous community consists of the Inner Baduy and Outer Baduy residents, with their settlement area in Kanekes Village, Leuwidamar District, Lebak Regency, Banten. The cultural norms of Sunda Wiwitan prohibit Baduy residents from adopting modern values in areas such as education, healthcare, and Information technology. However, the current communication reality contradicts the customary rules, as Outer Baduy residents use Information technology to support activities in agriculture, trade of agricultural products, and marketing of handicrafts.  The purpose of the study is to describe and analyze the phenomenon of the use of communication technology by the Baduy community. The ethnography of communication method is used to find the reality of interaction, practice and communication patterns. The Baduy indigenous community interacts with consumers through digital communication platforms. This reality can be reviewed from the perspective of symbolic interactionism and marketing communication.
The research was undertaken employing a qualitative approach and utilizing the method of virtual ethnography analysis. Data collection was conducted through direct observations within the Baduy community settlements, in-depth interviews with selected informants, engaging in Focus Group Discussions (FGDs), documentation of information content disseminated through social media platforms, as well as capturing photographic evidence. The application of the virtual ethnography method encompassed an analytical examination of the intricacies of communication realities, exploration of the roles assumed by communication actors, meticulous crafting of virtual messages, and an in-depth exploration of the utilization patterns observed in the realm of social media. The results showed that the communication behavior of the Baduy Kaduketuk Luar community is an adaptation of a mediated communication system. The use of communication technology media is done autodidactically. marketing communication is carried out by advertising, direct marketing to agents, social media publications, face-to-face communication, and word of mouth marketing.
Deindividuation Phenomenon among Anonymous Kpopers Account on Social Media X
Authors: Raisyah Siti Hafifah  , Nurrahmi Febri
Published: February 2025

Social media X allows its users to use anonymous accounts and hide their identities, leading Kpopers to prefer interacting anonymously. This study aims to describe the phenomenon of deindividuation that occurs among Kpopers using anonymous accounts on social media X. This study uses Social Identity of  Deindividuation Effect (SIDE) theory. Deindividuation refers to a state where the individual acts differently than usual because considers theirself to be part of group. It employs a descriptive qualitative method with a phenomenological approach and data collection techniques through semi-structured interviews with five anonymous Kpopers account users who actively interact on social media X. Observation and documentation of comments and activities of the informants on social media X were also conducted. The research results show that deindividuation can be seen in the anonymous Kpopers accounts on social media X when they use a fan account. The use of anonymous accounts causes user behavior to prioritize their identity as Kpopers and place greater importance on group norms rather than their personal norms. This deindividuation phenomenon occurs due to three factors, including anonymity, group immersion, and reduced identifiability. The anonymity factor occurs because anonymous Kpopers account users feel more comfortable and freer to express their opinions as Kpopers due to negative stigma towards those who idolize Kpop when revealing their real identity. Individuals first became Kpopers and did not experience group immersion, but when they joined social media X using an anonymous account, they began to show symptoms of group immersion. By joining the Kpopers group and using anonymous accounts as their identity, they focus more on their identity as Kpopers rather than as individuals. This causes them to start forgetting their personal identity (reduced identifiability).

Evaluating the Effect on Total Daily Insulin Dose in Adult Patients with Type 1 Diabetes Managed with Metformin and/or GLP-1 or GLP-1/GIP Receptor Agonists
Authors: Ahmed Mayeesha , Pierson Emily , Webster Molly
Published: February 2025

Purpose:
There are few studies that have assessed the utility of metformin and glucagon-like peptide-1 receptor agonists (GLP-1 RA) in type 1 diabetes (T1D), specifically looking at glucose control indices. These studies have largely evaluated the impact of agents not routinely used. Limited data exist on the use of the dual glucagon-like peptide-1/glucose-dependent insulinotropic polypeptide receptor agonist (GLP-1/GIP RA) in T1D. The objective of this study was to evaluate the effect of this growing practice in utilizing these common non-insulin therapies in T1D.
Methods:
This single-center, retrospective cohort study evaluated adult patients with T1D who received standard insulin therapy plus the following non-insulin therapies for at least 3 months: metformin; GLP-1 RA or GLP-1/GIP RA; or metformin and a GLP-1 RA or GLP-1/GIP RA (combination group). Data points were collected on starting dates of the first and second (if applicable) non-insulin agents, and the first office visit of at least 3 months on maximum tolerated doses. The primary endpoint was change in total daily insulin dose (TDD). Secondary and safety endpoints were evaluated in A1c, weight, and hypoglycemia.
Results:
A total of 110 of 366 patients met inclusion criteria. Changes in average insulin TDD were +4.06, -5.9 and -6.9 units for the metformin, GLP-1RA or GLP-1/GIP RA, and combination groups respectively (P =0.013). TDD after non-insulin therapy addition decreased in all patients on average 3.54 units (P =0.02). All groups saw significant decrease in A1c by 0.62%, weight by 3.8kg, and hypoglycemia was seen in 76% of patients.
Conclusions:
Non-insulin therapies added to standard insulin therapy in T1D resulted in decreased insulin requirement, increased glycemic control, and decreased body weight. While statistically significant, it remains unclear if the decreased insulin requirement is clinically significant. Further prospective studies are warranted to validate these findings.
Delayed Resilient Trajectory Tracking After Partial Loss of Control Authority over Actuators
Authors: Bouvier Jean-Baptiste , Panag Himmat , Woollands Robyn , Ornik Melkior
Published: February 2025

After the loss of control authority over the thrusters of the Nauka module, the International Space Station lost attitude control for 45 min with potentially disastrous consequences. Motivated by a scenario of orbital inspection, we consider a similar malfunction occurring to the inspector satellite and investigate whether its mission can still be safely fulfilled. While a natural approach is to counteract in real time the uncontrolled and undesirable thrust with the remaining controlled thrusters, vehicles are often subject to actuation delays hindering this approach. Instead, we extend resilience theory to systems suffering from actuation delay and build a resilient trajectory tracking controller with stability guarantees relying on a state predictor. We demonstrate that this controller can accurately track the reference trajectory of the inspection mission despite the actuation delay and the loss of control authority over one of the thrusters.
Model Predictive Guidance: A Fixed-Point Algorithm
Authors: Lu Ping , Davami Christopher
Published: February 2025

Tracking a reference trajectory is a frequent task in aerospace guidance. The technical approaches for tracking guidance design so far are largely application-dependent and heavily rely on labor-intensive practices such as manual gain generation. In this paper the model predictive control (MPC) method is used as the foundation for a systematic tracking guidance design, dubbed appropriately model predictive guidance (MPG). Unlike most existing work utilizing MPC, the method developed in this paper does not require a quadratic program (QP) solver. Instead, the constrained QP from the discretization of the MPC problem is strategically formulated in a novel way so that it has only box constraints. An exceedingly simple but globally convergent fixed-point algorithm with a theoretical guarantee is developed to solve the QP. The relatively general formulation of the MPG problem, the automated tracking command generation, and the very simple yet highly reliable algorithm render this method appealing to many tracking guidance problems and autonomous operations. The application of MPG is demonstrated in planetary powered descent guidance for a high-mass Mars mission.
Enhancing Productivity in Carbonate Wells with High-Permeability Contrast Through Combination of Non-Reactive Chemical Diverter and Single-Phase Retarded Acid System (SPRAS)
Authors: Mohammed Ali Dheyaa , Mohd Ahmad Muzakkir B , Amat Hadi , Choon Tan Boon
Published: February 2025

New wells drilled in the Middle East's vast carbonate fields face significant damage from drilling and completion operations, which severely impacts productivity. Damage can extend from a few inches to over 3 feet into the formation, impairing permeability across pay zones. Natural permeability contrast, due to carbonate build-up over time and depositional environments, also affects lower zone productivity, requiring near-wellbore permeability enhancement. Conventional hydrochloric acid (HCl) is ineffective due to its high reaction rate. A retarded acid system is essential for controlling reaction rates and improving wormhole development.

The new methodology employed a bullheading operation, combining a high-viscous non-reactive solids-free (HVNRSF) chemical diverter with a single-phase retarded acid system (SPRAS). Coiled tubing (CT) was used throughout the operation, beginning with perforation conditioning prior to acid treatment. Real-time fiber optics combined with coiled tubing (FOECT) and distributed temperature surveys (DTS) were employed to identify high and low intake zones, enabling on-the-fly adjustments to the diversion strategy and monitoring the diverter's effectiveness.

During the 3-well campaign, significant injection pressure increases were observed when diverter pills reached the formation. DTS data demonstrated more uniform acid distribution across perforated intervals compared to previous methods. Production contribution from the bottom zone was validated using production logging data. Continuous well test production monitoring post-treatment with SPRAS and HVNRSF diverter pills showed a ~25% increase in production, due to enhanced penetration into the lower permeability formation.

The combination of SPRAS and HVNRSF chemical diverters significantly improved matrix stimulation, leading to a ~25% production increase. This paper shares the experiences and lessons learned during the initial campaign and provides recommendations for further improvement and broader implementation in the field.

Published: February 2025

Multi-phase metering and testing of produced fluids from oil and gas wells is an indispensable daily task in oil fields. Efficient and accurate online metering of multiphase flow is a major proposition for lean management, digital transformation, and quality and efficiency improvement in oil fields. Multi-phase flow has complex components, changeable flow patterns, and a harsh on-site testing environment. The development of efficient, high-precision, widely applicable, and low-cost multi-phase metering methods and devices is a key technology to solve the above propositions, and it is also a global technical challenge. At present, metering in the metering room by tipping buckets and manual sampling and testing still dominate, with low precision and low efficiency, which seriously restricts the intelligent development of oil fields. In recent years, online metering and analysis technologies such as infrared, microwave, and radiation have developed, but their scope of application is narrow, their prices are high, and they have potential safety hazards, and they do not meet the conditions for large-scale promotion.

Magnetic resonance is a common laboratory detection technology for complex fluids and porous media. As a green, efficient and accurate means of quantitative oil and gas detection, it has been applied in the field of oil well logging. At present, the research on magnetic resonance technology in multiphase flow measurement and analysis has just started in the world, but it is widely recognized by the scientific and industrial communities as a technology with the most development potential for online oil and gas measurement and analysis. The breakthrough and application of online detection devices for oil and gas multiphase flow magnetic resonance can solve the problems existing in the existing separation and measurement technologies in an integrated manner.

With the depletion of oil and gas resources in old areas, reservoir transformation technologies represented by acid fracturing have become the main means for oil companies to increase production. The production data during the oil and gas testing stage is an important parameter for evaluating the fracturing effect. However, during the oil and gas testing stage, the flow rate of the produced fluid fluctuates greatly (e.g. the water content changes from 0 to 100%, and the gas-liquid ratio fluctuates from 0 to several thousand), which puts high demands on the range, frequency, and accuracy of the measuring instruments.
E-Line Solution for a Single-Run Combined Production Logging and ICD Shifting Operation: A Novel Approach
Authors: Mugharbil Mohammed K. , Albinhaji Zaid , Alnafjan Naif , Alharbi Yasser
Published: February 2025

The oil & gas industry has adopted intelligent completions with Inflow Control Devices (ICDs) extensively to achieve selective production and water control from various zones of a single reservoir. The conventional method to modify the opening/closing state of these ICDs involves coiled tubing (CT) with hydraulic shifting tools. This technique, however, has proven to be inefficient, inaccurate, and detrimental to the environment.

A novel approach was devised to overcome these challenges and improve operational efficiency, accuracy, and environmental sustainability, by integrating production logging tools (PLT) and an actuation device (Stroker) to adjust ICD positions through a single e-line conveyed tools string. This innovative solution deployed on E-Line enables the combination of the logging requirement with the ICD shifting into a single run, instead of the multiple runs required by a CT solution.

The E-line conveyed solution exhibited remarkable capabilities, such as conveying production logging tools in the horizontal section of the well to acquire production data and locate water-producing zones and shifting ICDs precisely. Post-shifting PLT data was utilized to accurately assess and demonstrate a reduction in water cut while the equipment remained downhole, ready to make any immediate adjustments to the other ICD positions.

The implementation of this solution resulted in a 50% reduction in operation time compared to conventional hydraulic CT shifting methods. Moreover, the transition to E-line technology significantly lowered harmful gas emissions, aligning with broader environmental sustainability goals. Additionally, the shifting solution proved its precision and reliability in ICD shifting, eliminating any uncertainty concerning the positioning of the ICDs.

The paper focuses on the authors’ experiences in the design, execution, and evaluation of this operation.

Published: February 2025

Conductor pipe partition system (CPPS) is a method that allow drilling more than one well from one conductor pipe (CP). Separation device consist of plate conveyed with tubing is run inside CP to segregate the wells and as a circulatory system. This technique could bring noteworthy advantages for the development of oil and gas field by decreasing the size and/or number of platforms and also to offer additional reserves access from current platform. Enormous cost saving by applying CPPS can be obtained up to 32 MUSD from the platform design and well construction.

Offshore Mahakam has been utilized CPPS since 2003 by more than 100 wells was built with this technique. Misalignment, twisted CPPS, cement ring, and collision risk are common problem during the construction. Practically with inclined and directional CP driven, the 1st well will be drilled below CP with tangent section around 2-3 stands and continue to shift direction as per target zone. Meanwhile for the 2nd well will directly kick-off below CP shoe and immediate keep at the distance to the 1st well drilled. By design, distance between well along inside CP are nearly close around 0.23 m which by default already below anti-collision standard. Failed troubleshoot might result on well integrity issue to loss of new slot.

Two cases casing integrity issue due to collision on splitter well was occurred while perform drilling splitter well in Offshore Mahakam. The first one on Sisi-Nubi field while drilling 2nd well surface section observed mud return from 1st well lateral valve outlet. The second integrity issue was happened on Bekapai field while 2 wells already completed drilling and set surface casing. During RIH BHA and perform choke drill inside surface casing on the 1st well, it is found unable to hold pressure and no mud return observed. Based on both of cases, reviving on casing integrity was performed by drilling rat hole and run smaller casing size that causes loss time and additional material equivalent to 1.4 MUSD.

Hence, proposed modification to make robust design and procedure is deployed to prevent those undesirable events appear in the future, such as: update on running BHA and kick-off procedure, bit design with shield, utilization of casing saddle, cementing strategy, and re-design CPPS supporting equipment. By those modifications, CPPS can still be one of the best options to optimize number of slot and well that can be drilled from the platform without compromise integrity and performance.
Modelling CO2 Injection in Shallow Context: The Case of Otway Shallow Fault Project

Published: February 2025

The present publication aims to illustrate key aspects of the modelling work underlying the operational design of the Otway Shallow Fault research project. The objective of this project is to provide a field demonstration of the interaction between CO2 and faults in the subsurface through the injection of a limited volume of CO2 in the Port Campbell Limestone aquifer at the Otway International Test Centre (Victoria, Australia).

An extensive subsurface study was conducted for targeting the operational design of the project, facing the challenging conditions posed by the shallow depth of the injection formation (about 70-80 m). The experimental observations available for deeper layers were the basis for the development of a Mechanical Earth Model (MEM), which was extended to shallower layers for the evaluation of the optimal injection pressure.

From a fluid dynamic side, the phase behavior is impacted by the specific formation pressure and temperature conditions. The solubility model involved in the numerical simulations needed specific calibration starting from literature data for the forecast of plume shaping in the formation.

The MEM approach offers valuable insights on the geomechanical behavior of the involved formations: the resulting stress regime transition from reverse to normal with depth aligns with regional geological observations, validating the findings. Uncertainty arises in the application of assumptions from deep sedimentary rocks to near-surface carbonates. While the model results suggest vertical stress as the threshold for safe injection, conservative recommendations favor data from extended leak-off tests performed in near offset wells, showing a gradient of 14.77 MPa/km.

On the other hand, the quantitative evaluation of the CO2 dissolution in the formation brine showed that the solubility trapping is the main drive for CO2 storage in such a shallow context. Its effect on the dynamic forecast of the size and shaping of the CO2 gaseous plume is noticeable, having also impact on the operative constraints of the field experiment and allowing to estimate the optimal volume of CO2 to be injected for the observation of its interaction with the fault.

Various uncertainties, mainly due to the limited availability of experimental data, were addressed by the studies presented. The results obtained allowed the construction of a dedicated numerical model for the accurate forecast of the CO2 behaviour in the subsurface.

The presented characterizations supported the operative phase of the project in a challenging context, mainly impacted by the shallow depth. Advanced monitoring techniques were designed and put in place for the field observation of the effects of CO2 injection. The analysis of the field data will allow to refine the calibration of the model inputs, while gaining the knowledge to be transferred on CCS projects at commercial scale.
Well Integrity: Similarities and Differences Between Dynamic Influx Management and Riser Gas Handling in Managed Pressure Drilling Applications
Authors: Ben-Fayed M. I. , Luis R. A. Gonzalez
Published: February 2025

The first common usage of MPD was as an Early Kick Detection System (EKDS). The next evolution of this implementation was to develop an Influx Management Envelope (IME) for Dynamic Influx Management (DIM), which focuses on mitigating, controlling, and circulating influxes during drilling operations within the primary barrier, emphasizing the dynamic nature of the wellbore conditions. In contrast, Riser Gas Handling primarily deals with gas influxes outside the constant bottomhole constraint. In 2023, an IADC committee issued guidance on Riser Gas Handling for deepwater wells that have Surface Backpressure (SBP) MPD systems. This adds another layer of consideration when dealing with influxes while drilling with MPD, which allows for the management of rising pressure and control of gas expansion in a safe and controlled manner. The analysis reveals similarities and differences between DIM and RGH methodologies. DIM dynamically manages influxes within the primary barrier, while RGH deals with gas influxes outside the primary barrier, especially in deepwater wells with Surface Backpressure (SBP) MPD systems.

Even with MPD operations evolving to include IME, the industry outlook, unfortunately, was to be viewed as a supplemental or bolt-on upgrade. In conventional drilling, the first line against the ability of the well to flow to the environment is a visible mud column whose combined pressure is greater than the formation's in situ pressure. The redundancy in the barrier is provided by the Blowout Preventer (BOP) stack, a crucial safety measure that acts as a secondary line of defense. This recognition should show how MPD is an integral part of well planning and shouldn't be seen as an upgrade or bolt-on feature. As an integrated part of well planning, well integrity analysis is necessary.

This paper will guide you through the analysis by highlighting the objectives of handling gas in the riser and circulating an influx out with an Influx Management Envelope. With the objectives described the data necessary to accomplish said objectives becomes easier to determine. Then, the barriers during an IME and the barriers in an RGH will have to be ascertained. Identifying the barriers and preservation thereof will make the process for RGH and IME easier to understand. With those two concepts clarified, the methodologies, equipment requirements, and operational challenges become easier to discuss. Analytical methods will be applied to compare the two methodologies, considering their respective effectiveness in managing well integrity.

Published: February 2025

The low permeability reservoir has the characteristics of large buried depth, high temperature, large lithologic change and high stress field, which leads to the inaccurate drilling mud density window based on the conventional wellbore stability analysis, resulting infrequent instability of the wellbore during the drilling process, and brings hidden dangers to drilling safety and environmental protection. By considering the influence of temperature effect on the borehole stress and adding the weak surface (fracture) instability condition based on Mohr-Coulomb destruction criterion, we proposed a method to determine the safe slurry density window of ultra-deep reservoir drilling according to six parameters: the minimum slurry density for shear instability and the maximum slurry density for tension instability in rock and weak surface, and the equivalent slurry density of pore pressure and minimum horizontal main stress. The application results of real data show that this method has good applicability and accuracy for the prediction of collapse pressure and leakage pressure in the ultra-deep complex formation in Baqu block of Karamay depression, and can provide effective reference for the actual borehole drilling design.

Исследование теоретико-методических аспектов экономической культуры и экономического мышления является актуальной задачей в условиях формирования «экономически грамотного» населения. В статье предложена методика исследования взаимосвязи экономической культуры и экономического мышления. Традиционные методы экономической науки, междисциплинарный синтез и институциональный подход дали возможность комплексно рассмотреть данные понятия, а качественный анализ теорий и нормативно-правовых документов позволил определить направление институциональных изменений со стороны государства. Сделан вывод о том, что экономическое мышление является базисом формирования идеологии института экономической культуры.

Introduction. The rapid development of the service industry, including the financial services sector, increases the requirements for the level of relevant competencies. This, in turn, necessitates the study of such categories as “economic thinking” and “economic culture”, as well as an assessment of the relationship between them. The research objective is to identify and systematize the foundations of the institution of economic culture, which determines the nature of economic thinking and the practice of making rational decisions. The research methods include analysis of materials from relevant domestic and foreign scientific publications, Russian regulations and subsequent synthesis of the foundations of the institution of economic culture. Results. The results of the study allow us to note the mutual influence and connection between economic culture and economic thinking in the conditions of a formed and functioning socio-economic system. The theory and methodology for studying the dependence of economic culture and economic thinking involves the integration of methods of economic science, interdisciplinary synthesis, and institutional approach. At the same time, the significance and the role of targeted institutional changes are beyond doubt since the modernization of the process of improving the quality of economic education and financial literacy of the population has become a priority area of government activity. Economic thinking has become not just a characteristic of an individual, including both conscious and unconscious; it is the mind, the intellect, psychological and social characteristics, a “way of life” in general, aimed at both analyzing and perceiving the information obtained in the process of thinking or feeling, and at the formation of a culture of behavior in the economy. Conclusion. An interdisciplinary approach encompassing methods of both economics and related social sciences and humanities, makes it possible to identify the role of economic thinking as the basis for the formation of the ideology of the institution of economic culture.

Introduction. In order to understand the essence of economic phenomena and be able to assess (analyze) particular economic situations correctly, it is necessary to develop economic thinking, which can be achieved by getting economics education and universal competencies in the field of economic culture, including financial literacy. The aim of the study is to explore the core concepts of economic culture, including financial literacy, as well as to develop an algorithm for mastering the universal competence to ensure competent and conscious economic behavior of Russian citizens, increasing their knowledge in the area of economics and finance. Results. The study revealed a relationship between the learning outcomes and the disciplines (practices) that facilitate the formation of students’ competence in the field of economic culture, including financial literacy, in accordance with the proposed model. A matrix was developed to ensure the achievement of all learning outcomes envisaged by the UC-10 competency in compliance with the proposed model. The main advantages of the model of forming the universal competence of students were structured and clearly demonstrated. To minimize risks and avoid losses of various types, a roadmap was developed for the transition to the proposed model of the universal competence formation in the field of economic culture, including financial literacy. Conclusion. The key aspects of financial literacy include knowledge of how to make a budget, plan for retirement, manage debt, and track personal expenses. Economically and financially savvy people with critical thinking skills and еру ability to compare and evaluate risks associated with certain financial products offered by financial institutions are developing competition. Economics education plays an essential role as an element of the system of formation of people’s economic culture and financial literacy.

Oppositely charged polymer-surfactant mixtures exhibit unique bulk and interfacial properties with many applications. For instance, cationic polymers paired with anionic surfactants are often used to deposit oils and lubricants on hair and skin upon dilution. These dilution-deposition systems are widely studied in simple mixtures but rarely in complex formulations. Thus, our paper focuses on cationic polysaccharides (cat-Guars and cat-HECs) paired with the anionic surfactant SLES-1EO (sodium laureth-1 sulfate) and incorporated into shampoos. We analyzed the polymer-surfactant complexes’ (PSCs) phase behavior, adsorption at the silicone/water interface, stickiness to bubbles (and drops), and deposition on hair-like substrates via phase behavior analysis, zeta potential measurements, foam film experiments, and imaging ellipsometry. Our results showed that the cat-Guar/SLES-1EO complexes exhibit wider precipitation regions and higher adsorption at the silicone/water interface than the cat-HEC/SLES-1EO complexes. The foam film experiments implied that only the cat-Guar/SLES-1EO complexes bridge the air bubbles as they form sticky PSCs. Imaging ellipsometry revealed that cat-Guars deposit thick, inhomogeneous layers of PSCs and silicone on the hair-like substrates, whereas cat-HECs deposit thinner layers or nothing. Together, these findings elucidate the underlying deposition mechanism and offer strategies to optimize the polymer performance in shampoo formulations via a comprehensive experimental protocol.

Aim. To evaluate the efficacy and tolerability of the combination of isatuximab, pomalidomide, dexamethasone (IsaPd) in the treatment of relapsed refractory multiple myeloma (RRMM) in a real clinical practice.
Materials and methods. The retrospective study included 60 patients (28 men and 32 women aged 39 to 81 years, median age 64 years) with refractory and relapsed forms of MM. All patients received isatuximab intravenously at a dose of 10 mg/kg (weekly during cycle 1 and once every 2 weeks in subsequent cycles), pomalidomide 4 mg orally once a day from day 1 to day 21 of the course, and dexamethasone weekly at a dose of 40 mg (if age 75 years) or 20 mg (if age ≥75 years). IsaPd courses of 28 days were administered until RRMM progression or unacceptable toxicity.
Results. The median follow-up was 17.3 months (range 2–34 months) and the median duration of response was 16.3 months (range 2–27 months). The overall response rate was 65.0%. Complete response was achieved in 5 patients (8.3%), very good partial response in 18 (30%), partial response in 16 (26.7%), minimal response in 5 (8.3%), stabilization in 3 (5%), and progression in 11 (18.3%). Median progression-free survival was 16.1 months (95% confidence interval 9.0–23.2 months), 12-month progression-free survival was 58.0%. Median overall survival was not reached, 12-month overall survival was 72.9%. The most common adverse events with this regimen were upper respiratory tract infections (32%) and neutropenia (35%).
Conclusion. The IsaPd combination demonstrates a favorable toxicity profile and high efficacy in patients with RRMM in the real clinical practice setting.

Aim. To evaluate the safety of sipavibart (AZD3152) for pre-exposure prophylaxis of COVID-19 in Russian population of participants at increased risk of developing severe COVID-19.
Materials and methods. Randomized, double-blind phase 2 NOVELLA study included adults who had an increased risk of severe COVID-19 and inadequate response to vaccination against COVID-19. Participants were randomly assigned in a 3:1 ratio to receive a single IM injection of sipavibart (300 mg) or placebo, and they were followed for up to 181 days. The primary safety end point was the incidence of adverse events (AEs) after a single dose of sipavibart.
Results. 116 participants were randomized (87 in the sipavibart group and 29 in the placebo group). Overall, 51.7% of participants in the sipavibart group and 58.6% of participants in the placebo group had at least one AE, most of which were Grade 1–2 in severity. AEs were well balanced between groups, with no meaningful differences for any categories. The overall frequency, severity and types of AEs do not suggest any safety concerns and are considered to be reflective of events generally observed in this immunocompromised population. The most commonly reported AEs were associated with infections and infestations (34.5% in both groups). There were no immediate AE or AE of special interest reported in the study. There were no related cases of ≥ grade 3 AEs or SAEs reported.
Conclusion. The safety data in NOVELLA demonstrated that the safety profile of sipavibart for pre-exposure prophylaxis of COVID-19 in Russian participants is considered to be acceptable.
