AbstractGeneral elections and regional head elections are a forum for presenting the people's wishes in electing their representatives in government institutions, including the campaign process as a forum for gaining support from the community. The availability of social media in the era of advances in information technology provides many alternative campaign methods for participants, one of which is campaigning via social media. Social media is a new set of communication and collaboration tools that create types of interaction by making it easier for users to participate, share and share content, including campaigning. The use of social media as a campaign medium certainly has negative and positive impacts. The positive impact is that apart from being more efficient in terms of costs, the message or vision and mission of the candidate pairs can be quickly and easily conveyed to the public. Meanwhile, the negative impact that can occur is the misuse of social media as a tool for carrying out black campaigns.Keywords: Campaign, social media; General elections; Regional head elections.

“Do what you need to,” I said.
As though this was extractingan arrowhead buried in flesh, not a sliver of wood from a pinky.
She my officemate, colleague,friend. But not – it occurred to me as she started to probe – a surgeon. Probably hadn’t fingered a forceps in years.
What I warn my patients against every day – not wise to compromisewith convenience.
I had no fear of pain.A dozen tours in the OR, years of drawing blood – we learn to distance, numb ourselves.
Numb ourselves, that is, to the pain of another – my pinky should have taken itself to Urgent Care.
Maybe there was hurt,but I never noticed. All I recall is a flood of sweetness, a drowsy warmth, as when the world is about to go dark.
Sometimes as we’re fallingwe hear a voice calling in the distance.
“Oh, shit – going vagal,” this one said.
It sounded like mine.
The “Greens” Against the Poor: Contradictions of Left Environmentalism
Authors: Davydov D.
Published: February 2024

The article examines the prospects of an alliance between the ideology of environmentalism and left-wing ideological trends aimed at solving the problems of the poor and socially vulnerable. It is noted that although the “greens” have often been criticized for their focus on the interests of the middle class and ignoring the material problems of the social “grassroots”, modern left-wing theorists increasingly associate the solution to the problem of global warming with the struggle for the material interests of the “exploited and oppressed” (representatives of the working class, precarious workers, poor residents of developing countries, minorities, etc.). It is assumed that the richest, not the poor, should pay for the energy transition; many jobs will be needed for such a transition; serious material climate damage will be prevented; residents of the poorest countries will benefit from the fight against global warming, because they are most vulnerable to droughts, floods and other potential catastrophic events. Today, it is also increasingly noted that “green” energy has already become competitive, and the main problem is in the selfish interests of capitalists. Nevertheless, as the author shows, despite the attempts of the “greens” to get closer to the “reds”, objective realities indicate a fundamental difference between the interests of environmentalists and those who today need basic material goods at present. “Green” energy has not become cheaper than fossil fuels, and attempts to radically accelerate the energy transition can lead to an economic, not a climatic, catastrophe. Moreover, it is impossible to solve all the problems at once: a choice is inevitable between urgent investments in the energy transition and the achievement of other socially significant goals: affordable education, free and high-quality medicine, housing construction for all those in need, and much more.

Kinesiophobia (fear of movement) has been recognized as a significant barrier to recovery and rehabilitation in patients after total knee arthroplasty (TKA). Our goal was to identify predictors of kinesiophobia and examine its correlation with early functional outcomes in TKA recipients. On the first and fifth postoperative days (POD1 and POD5), we evaluated pain using the International Pain Outcomes Questionnaire (IPO-Q) and created multidimensional pain composite scores (PCS). Pain Composite Score-total (PCStotal) assesses the overall impact of pain, taking into account outcomes of pain intensity, pain-related interference with function, and emotions and side effects. Functional status on POD 5 was determined by the Barthel index, 6-minute walking test, and knee range of motion. Kinesiophobia was measured on POD5 using the Tampa Scale for Kinesiophobia (TSK) and multivariable logistic regression was used to assess factors associated with kinesiophobia. Among 75 TKA patients, 27% exhibited kinesiophobia. The final regression model highlighted PCStotal on POD5 (OR=6.2, CI=1.9-19.9), PCStotal (OR=2.1, CI=1.2-3.8) on POD1, and the intensity of chronic pain before surgery (OR=1.4, CI=1.1-2.1) as significant kinesiophobia predictors. On POD5, those with kinesiophobia showed increased dependency, slower gait, and poorer knee extension recovery. This study highlights the importance of identifying and addressing kinesiophobia in TKA patients to optimize functional outcomes and improve recovery. Also, it is important to assess not only pain intensity but also the physical and emotional interference caused by pain, which can contribute to the development of kinesiophobia.
Creating An Array Of Parallel Vortical Optical Needles
Authors: Šlevas Paulius , Orlov Sergej
Published: February 2024

We propose a method for creating parallel Bessel-like vortical optical needles with an arbitrary axial intensity distribution via superposition of different cone-angle Bessel vortices. We analyze the interplay between the separation of individual optical vortical needles and their respective lengths and introduce a super-Gaussian function as their axial profile. We also analyze the physical limitations to observe well-separated optic needles, as they are influenced by mutual interference of the individual beams. To verify our theoretical and numerical results, we generate controllable spatial arrays of individual Bessel beams with various numbers and spatial separations by altering the spectrum of the incoming laser beam via the spatial light modulator. We demonstrate experimentally how to implement such beams using a diffractive mask. The presented method facilitates the creation of diverse spatial intensity distributions in three dimensions, potentially finding applications in specific microfabrication tasks or other contexts. These beams may have benefits in laser material processing applications such as nanochannel machining, glass via production, modification of glass refractive indices, and glass dicing.

Published: February 2024

Background: Poroid neoplasms (PN) are a heterogeneous group of tumors deriving from sweat glands and folliculo-sebaceous units. Their histological classification and clinical features are challenging. Our aim was to report clinicopathological features of poroid neoplasms. Methods: it is a retrospective study including all cases of poroid neoplasms registered at our Pathology laboratory of Niamey National Hospital (from February 2020 to February 2024). Results: We registered 13 cases of benign poroid neoplasms: 10 classic poromas (CP) (76.9%), 2 poroid hidradenomas (PH) (15.4%) and 1 dermal duct tumor (DDT) (7.7%). Nine cases (69.2%) had preoperative clinical diagnosis of malignancy. The mean age was 41.1 years (range of 12 – 70 years) with a slight female predominance (sex ratio = 1.16). Only 4/13 cases (30.8%) had classical palmoplantar locations. The tumors mean size was 3.7 cm (range of 0.4 – 8 cm). All cases were well-circumscribed solid (7/13 cases, 53.8%) or solido-cystic whitish nodules (6/13 cases, 46.2%). Clear cells were present in 7 cases (53.8%), apocrine ductal differentiation (mixed or pure) in 6 cases (46.2%), keratin horns in 2 cases (15.4%), squamous eddies in 6 cases (46.2%), melanin pigments in 1 case (7.7%) and sebaceous differentiation in 2 cases (15.4%). Conclusions: Unlike what is classically reported, our study shows that apocrine ductal differentiation, younger age and non-palmoplantar locations are common in poroid neoplasms. Also, PN are often diagnosed as malignant tumors by clinicians before histopathological analysis.

Published: February 2024

Technological advances in DBS hardware and software represent a significant growth area in functional neurosurgery. These advancements have the potential to significantly enhance treatment outcomes and expand the scope of neurological disorders that can be effectively addressed through DBS interventions. The introduction of directional DBS marks a new phase in neuromodulation, offering extended benefits for patients with Parkinson's disease, more efficient optimization of clinical outcomes, and targeted treatment of refractory symptoms through data-driven approaches. Implementing a multimodal programming strategy, incorporating novel current fractionation technology and image-guided tools for lead localization and brain sensing, further reduces reliance on traditional trial-and-error programming methods, paving the way for a more predictive application of this therapy. These advancements are expected to drive the development of sophisticated closed-loop stimulation systems capable of integrating continuous data streams for improved patient care.

Published: February 2024

Leptospira, which are known to be important disease-causing agents transmitted between animals and humans, results in significant illness and, in some cases, significant death in human populations. This study aims to examine the genomic structure of Leptospira interrogans serovar Copenhageni strain FDAARGOS_203 to identify the specific genetic factors that contribute to antimicrobial resistance (AMR) and defense against phages. The genome, consisting of two contigs totaling 4,630,574 base pairs, underwent thorough examination for protein-coding sequences, transfer RNA genes, and ribosomal RNA genes. A total of twenty-two antibiotic resistance genes that specifically target essential cellular processes such as cell wall synthesis, DNA replication, and protein synthesis have been identified. Significant among these were gidB, GdpD, and PgsA, each involved in separate aspects of antibiotic resistance. In addition, the investigation explored the defense mechanisms of bacteriophages, revealing the presence of defense islands that contain a range of anti-phage systems, including RM_Type_IV, PrrC, Borvo, CAS_Class1-Subtype-IC, and CAS_Class1-Subtype-IB. This comprehensive genomic analysis enhances our understanding of the molecular mechanisms that determine Leptospira's ability to adapt to various environments. The identified genetic factors linked to AMR and defense against phages not only enhance our scientific comprehension but also provide a basis for focused interventions to reduce the impact of leptospirosis.
Robust Estimations from Distribution Structures: III. Invariant Moments
Authors: Li Tuobang
Published: February 2024

Descriptive statistics for parametric models are currently highly sensative to departures, gross errors, and/or random errors. Here, leveraging the structures of parametric distributions and their central moment kernel distributions, a class of estimators, consistent simultanously for both a semiparametric distribution and a distinct parametric distribution, is proposed. These efficient estimators are robust to both gross errors and departures from parametric assumptions, making them ideal for estimating the mean and central moments of common unimodal distributions. This article also illuminates the understanding of the common nature of probability distributions and the measures of them.

Published: February 2024

Sixteen crossbred rabbits (New Zealand white x Thai native breed) were randomly divided into two groups of eight to determine the effects of daily oral administration of crude extracts from the butterfly pea (Clitoria ternatea L.) from weaning (at 35 days) to slaughter (at 90 days). Effects on phagocytic activity of blood polymorphoneuclear leukocytes, serum biochemistry, meat quality, muscular lipid peroxidation, apparent digestibility, and gut histology were studied. The results revealed that the phagocytic function of circulating leukocytes (75 and 90 days) and alveolar macrophages (90 days) did not differ between the two groups. At slaughter, treated rabbits had lower blood urea nitrogen concentrations and higher liver weight than control rabbits (p < 0.05). After chilling at 4°C for 24 hours, lower meat pH and alteration of meat color (a brighter, less yellow, Hue angle and color saturation) were observed in the treated group (p < 0.05). Furthermore, lipid peroxidation (measured at 3, 5 and 7 storage days) in the meat of treated rabbits was lower than in controls (p < 0.05). Apparent digestibility (analyzed at 46 days for four days) revealed improved organic matter and ether extracts in the treated group (p < 0.05), whereas gut histology was unaffected. In conclusion, butterfly pea extract supplementation did not affect phagocytic function but led to a modification in meat color, delayed lipid peroxidation, and improved digestibility.

Published: February 2024

Background: The enduring psychological effects of the COVID-19 pandemic continue to affect individuals long after the immediate health concerns have subsided. This research aims to identify specific groups within the Romanian population who are at a higher risk of experiencing mental health challenges that can interfere with everyday life and may lead to more serious mental health disorders.
Methods: Conducted as a cross-sectional survey, this study evaluated the prevalence and intensity of psychological distress using the DASS-21 questionnaire. An online survey distributed via Google Forms also gathered socio-demographic data and COVID-19-specific information. Statistical analyses included the Shapiro-Wilk test, Fisher's exact test, and Z-tests with Bonferroni correction. Quantitative independent variables that lacked a normal distribution were compared between groups using either the Mann-Whitney U test or the Kruskal-Wallis H test.
Results: Analysis of 521 questionnaires, filled out by a predominantly middle-aged cohort of 320 women and 201 men, revealed that 63.72% of participants worked outside the healthcare field. Those unemployed or retired reported significantly higher anxiety levels than individuals in other sectors. Moreover, living alone, experiencing the loss of close relatives (6.14%) or friends (33.59%), and undergoing hospitalization or reinfection due to COVID-19 were linked to significantly elevated distress scores.
Conclusion. By identifying the segments of the population most vulnerable to psychological distress, as evidenced by higher scores among the unemployed, retirees, individuals living alone, and those directly affected by COVID-19 through personal health or loss, targeted initiatives for psychological screening and therapy can be established. Such measures are essential for enhancing the post-pandemic mental well-being of Romanians, addressing the specific needs uncovered in this study.

Authors: Lailah Farihah Nishfah , Virgianita Asra
Published: February 2024

The trade war between the United States and the People's Republic of China (PRC) has attracted world attention because it was predicted to affect the global economy. The trade war started with the United States implementing high import tariffs on PRC products, to which the PRC then responded with similar actions. The application of this tariff is a response to the trade deficit that occurred to the United States in its trade with China. The United States' trade deficit with China has existed since 1989. Meanwhile, in 2017, the United States and China agreed to implement a 100-day plan aimed at opening up and expanding trade between the two countries. Thus, the question in this research is "Why did the United States launch a trade war against the People's Republic of China (PRC) in 2018?". The theory used in this research is trade expectations theory. The data sources are official United States government documents, World Bank reports and various journals related to this theme. This paper aims to analyze the causes of the United States launching a trade war against the PRC in 2018. The result of this research is The United States launched a trade war against the PRC was because of the United States' negative expectations of the PRC which made the United States choose war against the PRC even though there was high dependence between the two countries. Negative expectations of the United States were assessed by trade deficit aspect, foreign investment aspect, employment and unemployment rate, and public opinion.

Published: February 2024

Wood chips are the primary sources of raw materials for numerous industries, including pelleting mills, biorefineries, pulp-and-paper industries, and biomass-based power generation facilities. Unfortunately, when wood chips are utilized as a renewable and environmentally friendly resource, industries are constantly challenged by the consistency of the wood chip qualities (e.g., moisture/ash contents, size distributions) - a historically recognized problem on a global scale. Among other wood chip quality attributes, the moisture content is considered the most pressing one as it directly impacts the energy content, storage stability, and handling properties of the raw and finished products. Therefore, accurate wood chip moisture content prediction can help optimize the drying process and reduce energy consumption.

The objective of this work is to describe the extent of productivity decline due to fines migration during periods of increasing water-cut. Two models are presented which allow for estimating the formation damage due to fines migration in both homogeneous and heterogeneous reservoirs.

The model utilizes a description of the fluid distributions withing the pore structure to determine the fines detachment during progressive sweep of the reservoir by an aquifer. In heterogeneous reservoirs, an extension of the Dietz model is used to calculate pseudo relative permeability curves accounting for any arbitrary permeability distribution in a layer-cake reservoir. Both models are compared with field productivity decline data to evaluate their validity.

Both models allow for explicit predictions of the wellbore productivity during periods of increasing water-cut. A novel diagnostic plot, the well impedance plotted against the well fractional flow, allows for the isolation of the formation damage characteristics of the reservoir. Tuning the formation damage and reservoir properties using field data exhibits good agreement and allows for extrapolation of the curves to higher water cuts. The models provide unique insight into the future formation damage of the well and allow for strategic planning of well remediation and stimulation. For heterogeneous reservoirs, the new diagnostic plots are proven to be linear, regardless of the permeability distribution in the reservoir, providing a quick and easy tool for formation damage evaluation.

The new models and diagnostic plot provide a simple method to extrapolate existing formation damage and estimate formation damage from laboratory studies and/or well analogues.
Experimental Characterization of Linear Swelling of Reactive Clays Dominated Wells: Comparison of Drilling Fluid Systems

Published: February 2024

Shale drilling remains one of the oil industry's most challenging and expensive operations. One of the main concerns in shale drilling is the instability of the wellbore, which can be attributed to the physio-chemical interaction between the drilling fluid systems and the shale formation. This poor interaction is primarily caused by the presence of high-reactive clays, which are known to cause swelling and dispersion issues during drilling. This paper evaluates the linear swelling characteristics of a shale formation dominated by high-reactive clay. A comparative analysis of various drilling fluids’ performance in controlling shale swelling is performed for four (4) clay-dominated wells drilled in the Tuscaloosa Marine Shale (TMS). The mineralogy concentration of samples obtained from different wells drilled in the shale formations is characterized using Fourier-transform infrared spectroscopy (FTIR). Additionally, clay swelling tests are performed in accordance with the American Society of Material Testing (ASTM) Standard Section D5890 to determine the swelling indices of the wells under investigation when exposed to different drilling fluid systems. The study reveals that all the wells tested have a clay concentration of at least 50%. Furthermore, the choice of drilling fluid systems significantly affects the swelling rate. High-performance water-based mud (HPWBM) systems, such as KCl and high salinity formate brine, exhibit improved swelling inhibition and compatibility with high-reactive shale formations. The study revealed that the use of high-performance water-based systems reduces the swelling tendency of clay by as much as 60% compared to conventional water-based systems. The use of inhibitive mud systems also minimized the size of the opening of the tetrahedral sheet of the clay during water invasion as opposed to the conventional water-based mud systems.
How High-Resolution Visualisations and Quantifications Gave Insight into Damaging Mechanisms and Treatment Fluid Performance in Omani Carbonate Reservoirs

A study was carried out to examine Formation Damage mechanisms caused by drilling and completion fluids in onshore wells in Oman. A specific understanding of what caused any damage was important, as this data would be used to help select treatment fluid options and assess their suitability. Two phases of corefloods looked at the compatibility of drilling mud and displacement fluid with reservoir core, and two further phases considered a range of treatment options. Treatment fluids included different strengths of hydrochloric acid, with and without solvent. The initial phases showed moderate to very high levels of permeability reduction, predominantly caused by the nature of the drilling mud-cakes and incomplete clean-up during drawdown. 15% HCl was successful in removing much of the operational fluid damage but was typically not forming wormholes. Including a solvent seemed to aid in wormhole development but left some of the operational fluid damage at the wellbore. Using only traditional metrics such as permeability measurement, filtrate loss volumes, and electron microscopy, it was difficult to see differences between the treatment options; when adding in the visualisations and quantifications there were clear variances in behaviour. Taking this integrated approach was therefore key to gaining a proper understanding of damaging mechanisms, how they could be removed or bypassed, and whether treatment fluids worked as intended.
The Value of Underbalanced Coiled Tubing Drilling UBCTD in Unconventional Mature Fields: Decision Analytic Approach
Authors: Al-Sharea Maher. Falih.
Published: February 2024

Under-balanced Coiled Tubing Drilling (UBCTD) is a promising method for the redevelopment of unconventional mature reservoirs through re-entries. Yet, such projects have unique technical, geological and economic challenges. Thus, the commercial value is not fully realized. In this paper, we discuss an appraisal method that consider the best number of re-entries subject to technical, geological and economic uncertainties.

The methodology involves three main components: 1. Reviewing key papers to assess the primary benefits of underbalanced drilling, and identifying uncertainties related to its applications. 2. Evaluating the appropriateness of coiled tubing drilling for underbalanced applications, including the associated costs. 3. Developing a decision-analytic framework to facilitate sound decision-making regarding the optimal number of re-entries. Our valuation method is based on describing uncertain factors, both technical and economical, and using them in a consistent valuation framework to support analysis and decision-making. The valuation framework also reveals the economic threshold for drilling wells, generating general managerial decision insights.

Through this method, we show that technical and market factors influence the decision to use this technology in the development of unconventional mature fields. In this context, determining the number of re-entries is contingent upon the economic threshold, which, in turn, is influenced by market uncertainties. This necessitates employing consistent models to estimate the level of confidence for future oil prices.

The proposed workflow provides consistent modeling of the key uncertain factors in a straightforward decision-making framework.
