Seborrheic keratosis (SK) and Bowen disease (BD) are different entities in dermatopathology. Differentiating between these two is important and can sometimes be a challenge for the pathologist, who may need to rely on complementary techniques. To obtain a reliable distinction, several immunohistochemistry markers have been explored such as p16 and Ki67, being positive in Bowen disease and negative in Seborrheic keratosis. Ki-67 is a non-histone protein associated with ribosomes and a well-known marker of cellular proliferation, overexpressed in Bowen disease. In addition, it has been related to a greater expression of antigens associated with the growth and differentiation of keratinocytes. P16 is a tumor suppressor gene that inhibits cyclin-dependent kinases 4 and 6. His inactivation leads to a unregulated proliferation of the cell cycle. A greater expression was found in Bowen Disease compared to Seborrheic Keratosis. Immunohistochemistry allows the distinction between entities that may be appear similar both clinically and histopathologically. This is of utmost relevance since proper treatment depends on a precise diagnosis.

Burn injuries are a significant cause of admissions to burn and plastic surgery units. One treatment modality for burn injury patients is hyperbaric oxygen therapy (HBOT). HBOT exposes patients to high concentrations of oxygen at increased atmospheric pressure levels. It can enhance burn wound healing by promoting cellular response, inflammatory cytokines, neovascularization, and collagen formation. This review explores the role of HBOT in enhancing burn wound healing, particularly in plastic surgery. We gathered and analyzed information from various web databases, using specific keywords related to burn wound injuries and HBOT. Inclusion criteria encompassed open-access journals and articles relevant to the subject matter. This review revealed that despite some controversial findings and the absence of treatment guidelines for burn patients, HBOT can complement other modalities. Side effects may include neurological and ophthalmic toxicity, as well as mild effects such as nausea and gastrointestinal disturbance. In conclusion, HBOT serves as an adjunctive therapy for promoting wound healing, including in burn patients. Evidence suggests its effectiveness in plastic surgery, potentially reducing hospital stays, costs, and recovery times. Further prospective randomized controlled trials with larger sample sizes and blinding are necessary to address remaining controversies and evaluate the full benefits of HBOT.

The horticultural sector in Kenya plays a crucial role in driving the country’s economy, making up approximately 1.6% of the country’s GDP in 2019. Despite generating a significant Ksh152.3 billion in 2022, the value of these exports exhibited a decline compared to Ksh157.7 billion in 2021. These decreases in horticultural exports performance warrant further investigation into the underlying factors impacting this important sector. This study examines the role of government effectiveness in the relationship between different macroeconomic factors and Kenya’s horticultural exports performance using time series data from 1990 to 2021. The study’s key findings highlight the significant influence of government effectiveness on the relationship between exchange rates, inflation rates, interest rates, and horticultural export performance. This implies that well-designed government policies have the potential to enhance the positive impacts of these macroeconomic factors. The findings highlight the crucial role of government effectiveness in shaping the impact of macroeconomic factors on Kenya’s horticultural export performance. Considering these findings, the study provides a few policy recommendations. Investments in strengthening government institutions and policies can amplify the benefits of favourable exchange rates, controlled inflation, and stable interest rates on horticultural exports. Additionally, taking steps to enhance market access, decrease trade barriers, and negotiate more favourable trade agreements can amplify the advantages of favourable terms of trade for horticultural exports. Lastly, it is important to consider policies that can help address the negative effects of unfavourable terms of trade. This includes strategies like export diversification and risk management, which can be particularly effective with strong government backing.
Analyzing the Determinants of Trade Balance: An Empirical Investigation of Indonesia's Economic Dynamics
Authors:   Faculty of Economics and Business Indonesian International Islamic University, Nyange Asia Khamis , Jonas Ajibu ,   Faculty of Economics and Business Indonesian International Islamic University
Published: May 2024

The study investigates the determinants of Indonesia's trade balance focusing on five key factors: money supply, foreign direct investment, exchange rate, carbon dioxide emissions, and government expenditure. Utilizing secondary time-series data from 1990 to 2022 and employing vector error correction model analysis, the research reveals significant insights. In the short term, only the money supply notably influences trade balances, while the other factors show no significant impact. However, in the long term, foreign direct investment, exchange rate, carbon dioxide emissions, and government expenditure positively affect the trade balance, with the money supply displaying an insignificant impact. The study's conclusions offer policy suggestions to address these findings. These suggestions include putting policies in place to lower carbon emissions and encourage sustainable growth, making sure government funding for sustainable development initiatives is used effectively, luring foreign direct investment, keeping exchange rates stable, and being cautious when controlling the money supply to preserve price stability. The objective of these recommendations is to improve Indonesia's trade balance sustainability. However, the analysis admits its limitations in not accounting for all macroeconomic factors, such as GDP, interest rates, and industrial production, that affect trade balance. Notwithstanding these drawbacks, the study provides insightful information to help policymakers develop plans for enhancing the dynamics of Indonesia's trade balance.

This article is the result of research on the various customs of the Lampung people, where Indonesia is a pluralistic society that adheres to various ethnic groups, religions and beliefs, and comes from diverse indigenous peoples. These differences are shown in human daily activities in their social interactions in society. , from the human being is born until he dies. Customary law is born from a behavior that is continuously carried out in which there is a certain pattern that its existence is maintained so that it becomes a habit and is recognized by the community groups in it as a tradition called adat. Likewise, the Lampung Community, which is also one of the indigenous peoples in Indonesia, which is plural in nature with a variety of language dialects, customs, and diverse lifestyles. This diversity then gave birth to a diverse culture as well. More specifically, this article discusses how the distribution of patrilineal inheritance in the Lampung Indigenous community when viewed from the perspective of Maslahah. If the distribution of traditional inheritance in Lampung is applied standardly, then the inheritance rights completely fall to the eldest son by overriding the rights of the daughter to get her inheritance rights. Meanwhile, Islam highly upholds women's rights, including in terms of inheritance distribution. To answer the problems that arise related to this, this study uses a qualitative descriptive method. then this is not in accordance with the principle of benefit, so that it does not reflect a balanced sense of justice as the Word of Allah SWT which is explained in the Qur'an about several provisions of inheritance law for the benefit of mankind, both men and women.

This study investigated the suitability of drinking water in Orlu, Nigeria, facing challenges due to limited surface water availability and environmental deterioration. To solve the problem of the availability of portable water, electrical resistivity surveys using a Schlumberger array were conducted to identify potential groundwater resources. Twelve locations were assessed, revealing resistivity values indicative of potential aquifers. Following the geophysical survey, the physicochemical properties of water samples collected from various locations were analyzed. Parameters including pH, dissolved oxygen (DO), total dissolved solids (TDS), and minerals were evaluated against WHO and Nigerian drinking water standards. The analysis indicated generally good water quality across the sampling sites. pH levels were within the recommended range, and DO concentrations met the minimum requirements. Similarly, TDS and BOD values suggested low levels of organic matter and dissolved solids. Mineral content also remained below WHO-permissible limits. A Water Quality Index further confirmed that the water quality within the study area can be graded from good to excellent in quality. These findings suggest that the groundwater resources identified in the study hold promise for providing safe drinking water in Orlu and its environs.

Authors: He Yi , Wang Xi , Paolinelli Luciano , Young David , Mohamed-Saïd Maalek , Singer Marc
Published: May 2024

Produced water can cause internal corrosion in oil pipelines. The flow of hydrocarbons and water can result in intermittent surface wetting, impacting corrosion inhibition. However, this is still poorly understood. This research uses electrochemical techniques to study the impact of intermittent wetting and the wettability of the steel surface on corrosion inhibition. An inhibitor model compound and model oil were used at 25°C and 55°C in CO2-saturated solutions. Corrosion inhibition varied with temperature and steel surface hydrophobicity, altering inhibition significantly after intermittent contact with hydrocarbon at 55°C. Electrochemical impedance spectroscopy and wettability results revealed distinct protective mechanisms when oil was present.
Value of computed tomography pulmonary angiography measurements in predicting 30-day mortality among patients with acute pulmonary embolism
Authors: Akcalar Zorlu Seray
Published: May 2024

Purpose

Late diagnosis is associated with high mortality rates in acute pulmonary embolism (PE), so early diagnosis and risk assessment are crucial. We aim to evaluate computed tomography pulmonary angiography measurements to identify relationships with 30-day mortality in patients with pulmonary embolism. This study investigated the utility of computed tomography pulmonary angiography (CTPA) measures in determining 30-day PE-related mortality and identified various echocardiographic, demographic, and clinical variables that were independently associated with short-term mortality in patients with acute PE.

Material and methods

This retrospective study examined data from July 2018 to April 2023. A total of 118 patients were included in the study. Clinical and demographic characteristics, laboratory findings, echocardiographic data, and CTPA images were retrieved from the electronic database and patient charts.

Results

The rate of 30-day mortality was 14.41%. Deceased patients were significantly older than survivors (73.53 ± 14.17 vs. 60.23 ± 17.49 years; p = 0.004), but the sex distribution was similar. In multivariable logistic regression, having received radiotherapy for malignancy, high pulmonary artery obstruction index % (> 46.2), high left pulmonary artery diameter (> 23.9 mm), and high coronary artery calcification score (> 5.5) were independently associated with mortality.

Conclusions

These results reveal specific parameters that can assist acute PE management by enabling the identification of critical events. Despite promising results in predicting short-term mortality in acute PE, further prospective cohort studies are needed to confirm the results of the present study.

Political Speech from Corporate America: Sparse, Mostly for Democrats, and Somewhat Representative
Authors: Barari Soubhik
Published: May 2024

How do corporations engage in political speech in the age of social media? Evidence suggests that online corporate brands employ a variety of partisan signals which include not only ideological positions but also more subtle, implicit appeals to partisans. Identifying and scaling a broad range of these signals in ≈2 million Twitter and Insta- gram posts from the 1,000 most popular corporate brands in the United States, I find that most corporate brands’ speech mirrors the speech of Democrats, but this is concentrated in a handful of brands and occurs in uneven bursts across time. Moreover, this communication is not as dishonest as popular narratives suggest: the majority of brands’ partisan speech well represents the political preferences of key stakeholders (e.g. employees, voters, and consumers) and is at least somewhat informative about corporate governance priorities (e.g. political spending, DEI outcomes, and cli- mate policy). These results provide a measured counterbalance to popular narratives of ‘woke capitalism’, suggesting that political speech from corporate America is, at worst, sometimes inconsistent with stakeholders and firm agendas rather than outright hypocritical.

Published: May 2024

Abstract. There are growing concerns about the climate impacts of absorbing organic carbon (also known as brown carbon, BrC) in the environment, yet its chemical composition and association with the light absorption capabilities remain poorly understood. This study characterized water-soluble and water-insoluble organic carbon (WSOC and WIOC) from residential solid fuel combustion at the molecular level and evaluated their quantitative relationship with mass absorption efficiency (MAE). The MAE values at λ = 365 nm from biomass burning were significantly higher than those from coal combustion (p < 0.05). Thousands of peaks were identified in the m/z range of 150–800, with the most intense ion peaks occurring between m/z 200–500 for WSOC and m/z 600–800 for WIOC, respectively. The CHO group predominated in the WSOC extract from biomass burning emissions, while sulfur-containing compounds (SOCs) including CHOS and CHONS were more intense in the WIOC extract, particularly from coal emissions. Emissions of the CHON group were positively correlated with the fuel nitrogen content (r = 0.936; p < 0.05), explaining their higher abundance in coal emissions compared to biomass. The SOC emissions were more predominant during flaming phases, as indicated by a positive correlation with modified combustion efficiency (MCE) (r = 0.750; p < 0.05). The unique formulas of coal combustion aerosols were in the lower H/C and O/C regions, with higher unsaturated compounds in the van Krevelen (VK) diagram. In the WIOC extract, coal combustion emissions contained significantly higher fractions of condensed aromatics (32 %–59 %) compared to only 4.3 %–9.7 % in biomass burning emissions. In contrast, the CHOS group in biomass burning emissions was characterized by larger condensed aromatic compound fractions than those in coal combustion. Moreover, the CHOS aromatic compound fractions were positively correlated with MAE values in both WSOC (r = 0.714; p < 0.05) and WIOC extracts (r = 0.929; p < 0.001), suggesting that these compounds significantly contributed to MAE variabilities across different fuels.
Impact ionization double peaks analyzed in high temporal resolution on Solar Orbiter

Published: May 2024

Abstract. Solar Orbiter is equipped with electrical antennas performing fast measurements of the surrounding electric field. The antennas register high-velocity dust impacts through the electrical signatures of impact ionization. Although the basic principle of the detection has been known for decades, the understanding of the underlying process is not complete, due to the unique mechanical and electrical design of each spacecraft and the variability of the process. We present a study of electrical signatures of dust impacts on Solar Orbiter's body, as measured with the Radio and Plasma Waves electrical suite. A large proportion of the signatures present double-peak electrical waveforms in addition to the fast pre-spike due to electron motion, which are systematically observed for the first time. We believe this is due to Solar Orbiter's unique antenna design and a high temporal resolution of the measurements. The double peaks are explained as being due to two distinct processes. Qualitative and quantitative features of both peaks are described. The process for producing the primary peak has been studied extensively before, and the process for producing the secondary peak has been proposed before (Pantellini et al., 2012a) for Solar Terrestrial Relations Observatory (STEREO), although the corresponding delay of 100–300 µs between the primary and the secondary peak has not been observed until now. Based on this study, we conclude that the primary peak's amplitude is the better measure of the impact-produced charge, for which we find a typical value of around 8 pC. Therefore, the primary peak should be used to derive the impact-generated charge rather than the maximum. The observed asymmetry between the primary peaks measured with individual antennas is quantitatively explained as electrostatic induction. A relationship between the amplitude of the primary and the secondary peak is found to be non-linear, and the relation is partially explained with a model for electrical interaction through the antennas' photoelectron sheath.
Carbon-climate feedback higher when assuming Michaelis-Menten kinetics of respiration
Authors: Beer Christian
Published: May 2024

Abstract. Earth system models simplify complex terrestrial respiration processes assuming a first-order chemical reaction or assuming a Michaelis-Menten kinetics. The epistemic uncertainty related to the respective mathematical representations is unclear. Using a simplified model of biogeochemical feedbacks to climate, we show that the terrestrial carbon-climate feedback is more than 35 % higher, and hence the remaining carbon budget to keep global warming below 2 °C is 89–158 Pg C higher, when assuming Michaelis-Menten kinetics instead of first-order kinetics, but these differences depend on the underlying emission scenario. These results show the importance of an increased understanding of the mathematical model structure of respiration processes in Earth System Models for more reliably projecting future carbon dynamics and climate, related feedback mechanisms, and hence to estimate a valid remaining anthropogenic carbon budget.

Abstract. Accurate long-term daily cloud-gap-filled fractional snow cover products are essential for climate change and snow hydrological studies in the Asian Water Tower (AWT) region, but existing Moderate Resolution Imaging Spectroradiometer (MODIS) snow cover products are not sufficient. In this study, the multiple-endmember spectral mixture analysis algorithm based on automatic endmember extraction (MESMA-AGE) and the multistep spatiotemporal interpolation algorithm (MSTI) are used to produce the MODIS daily cloud-gap-filled fractional snow cover product over the AWT region (AWT MODIS FSC). The AWT MODIS FSC products have a spatial resolution of 0.005° and span from 2000 to 2022. The 2745 scenes of Landsat-8 images are used for the areal-scale accuracy assessment. The fractional snow cover accuracy metrics, including the coefficient of determination (R2), root mean squared error (RMSE) and mean absolute error (MAE), are 0.80, 0.16 and 0.10, respectively. The binarized identification accuracy metrics, including overall accuracy (OA), producer's accuracy (PA) and user's accuracy (UA), are 95.17 %, 97.34 % and 97.59 %, respectively. Snow depth data observed at 175 meteorological stations are used to evaluate accuracy at the point scale, yielding the following accuracy metrics: an OA of 93.26 %, a PA of 84.41 %, a UA of 82.14 % and a Cohen kappa (CK) value of 0.79. Snow depth observations from meteorological stations are also used to assess the fractional snow cover resulting from different weather conditions, with an OA of 95.36 % (88.96 %), a PA of 87.75 % (82.26 %), a UA of 86.86 % (78.86 %) and a CK of 0.84 (0.72) under the MODIS clear-sky observations (spatiotemporal reconstruction based on the MSTI algorithm). The AWT MODIS FSC product can provide quantitative spatial distribution information on snowpacks for mountain hydrological models, land surface models and numerical weather prediction in the Asian Water Tower region.

Implementation and evaluation of diabatic advection in the Lagrangian transport model MPTRAC 2.6
Authors: Clemens Jan , Hoffmann Lars , Vogel Bärbel , Grießbach Sabine , Thomas Nicole
Published: May 2024

Abstract. Diabatic transport schemes with hybrid zeta coordinates, which follow isentropes in the stratosphere, are known to greatly improve Lagrangian transport calculations compared to the kinematic approach. However, some Lagrangian transport calculations with a diabatic approach, such as the Chemical Lagrangian Transport Model of the Stratosphere (CLaMS), are not well prepared to run on modern high-performance computing (HPC) architectures. Here, we implemented and evaluated a new diabatic transport scheme in the Massive-Parallel Trajectory Calculations (MPTRAC) model. While MPTRAC can be used either with shared-memory multiprocessing on CPUs or with GPUs to offload computationally intensive calculations, making it flexible for many HPC applications, it has been limited to kinematic trajectories in pressure coordinates. The extended modelling approach now enables the use of either kinematic or diabatic vertical velocities and the coupling of different MPTRAC modules based on pressure or hybrid zeta coordinates. This study focus on the accuracy of the implementation in comparison to the CLaMS model. The evaluation of the new transport scheme in MPTRAC shows that, after 90 d of forward calculations, distributions of air parcels in the upper troposphere and lower stratosphere (UTLS) are almost identical for MPTRAC and CLaMS. No significant bias between the two Lagrangian models was found. Furthermore, after 1 d, internal uncertainties (e.g. due to interpolation or the numerical integration method) in the Lagrangian transport calculations are at least 1 order of magnitude smaller than external uncertainties (e.g. from reanalysis selection or downsampling of ERA5). Differences between trajectories using either CLaMS or MPTRAC are on the order of the combined internal uncertainties within MPTRAC. Since the largest systematic differences are caused by the reanalysis and the vertical velocity (diabatic vs. kinematic), the results support the development efforts for trajectory codes that can access the full resolution of ERA5 in combination with diabatic vertical velocities. This work is part of a larger effort to adapt Lagrangian transport in state-of-the-art models such as CLaMS and MPTRAC to current and future HPC architectures and exascale applications.
Brief communication: Testing a portable Bullard-type temperature lance confirms highly spatially heterogeneous sediment temperatures under shallow bodies of water in the Arctic

Abstract. The thermal regime in the sediment column below shallow bodies of water in Arctic permafrost controls benthic habitats and permafrost stability. We present a robust, portable device that measures detailed temperature–depth profiles of the near-surface sediments in less than 1 h. Test campaigns in the Canadian Arctic and on Svalbard have demonstrated its utility in a range of environments during winter and summer. Measured temperatures were spatially heterogeneous, even within single bodies of water. We observed the broadest temperature range in water less than 1 m deep, a zone that is not captured by single measurements in deeper water.
A nova lei de licitações e as modas de solução de conflitos nos contratos administrativos
Authors: Barenco Corrêa de Mello Marcílio
Published: May 2024

The New Brazilian Law on Bids and Administrative Contracts provides in its own chapter about alternative means of resolving disputes, arising from the technique of the multi-door system of access to justice, where interested parts (public administration and private contractor) have at their disposal various forms of outcome for conflicting issues through extrajudicial means. This article brings as its object of study the consensual methods of resolving disputes provided for in Brazilian Federal Law nº 14.133/2021, with emphasis on the use of arbitration, conciliation, mediation and the dispute board, with the possibility of using other mechanisms arising from private autonomy, in addition to state jurisdiction itself. In this sense, the commitments and agreements signed for the consensual resolution of disputes can contribute to the correction of defects and the final delivery of the contracted object for the benefit of society, without the need for the issue to be submitted to the barriers established within the scope of the heterocompositive judicial process. There is, however, a need to move beyond the idea of unilateral, imperative administration, towards a new form of dialogical administration today, revisiting the concepts of unavailability of the public interest and reservation of jurisdiction, in order to reach the intended purposes.
Narratividad y mito en el videojuego de mundo abierto de fantasía épica. Mitos textuales, ambientales y performativo
Authors: Antonio Castro Balbuena
Published: May 2024

Este ensayo estudia la narratividad y el mito en el videojuego. Para ello, se explora la relevancia de los elementos narrativos en este soporte, como los personajes y el espacio, con la inclusión de una característica única: la interacción. A partir de la conexión del videojuego con las historias espaciales, como la fantasía épica, se profundiza en la relevancia del mito en los videojuegos de mundo abierto para proponer una clasificación de mitos en este soporte: los mitos textuales, más cercanos a la tradición y que se expresan en código textual; los mitos ambientales, resultado de la condición hipermedial del videojuego y la conducta arqueológica del jugador; y los mitos performativos, creados por el jugador con sus decisiones y movimiento. Por último, se desarrolla esta propuesta mediante el breve análisis de dos videojuegos de mundo abierto: World of Warcraft y Dark Souls III.

This study investigates the impact of transformational management on organizational alternate effectiveness within multinational groups working in Baluchistan, Pakistan. Recognizing the dynamic and hastily evolving commercial enterprise surroundings, this research emphasizes the important role of leadership in navigating via organizational alterations. The look is grounded inside the theoretical framework of transformational management and is posited to influence organizational change tactics seriously, fostering innovation, motivation, and collective imagination and prescience among employees. Through a quantitative study’s methodology, facts were accrued from mid-level managers at Mondelez International, Hub, and Cnergyico Pakistan Limited, Hub, using the Multifactor Leadership Questionnaire (MLQ) and Project Implementation Profile (PIP) survey contraptions. The findings reveal a wonderful correlation between transformational leadership and organizational trade effectiveness, highlighting the importance of transformational leadership behavior, including intellectual stimulation, inspirational motivation, and individualized consideration, in enhancing the success of alternate projects. This takes a look at contributing to the existing body of knowledge by presenting empirical proof of the effectiveness of transformational management in managing organizational change inside the unique socio-economic and cultural context of Baluchistan. The implications of this study are massive for multinational agencies in search of powerful exchange management techniques in diverse and tough environments in force.

Fast dissolving Tablets are disintegrating and/or dissolve rapidly in the saliva without the need for water. FDTs can be prepared by different methods as direct compression, freeze-drying, spray drying, sublimation and wet granulation method. Herbal drugs comprise of a major share of all the officially recognised systems of health in India. The herbal extract of Achyranthes aspera Linn was used in this formulation. The aim of this study was to formulate FDTs with sufficient mechanical integrity and to achieve faster disintegration in the oral cavity without water. To achieve this goal, MCC is used as diluent and sodium saccharin as sweetening agent for the formulation of tablets. Attempts were made to enhance dissolution rate along with faster disintegration using superdisintegrants like Crospovidone, Sodium starch glycolate (SSG) and mixture of crospovidone and sodium starch glycolatein the formulation of tablets. The tablets were subjected to weight variation, drug content uniformity, hardness, friability, wetting time, In vitro dispersion time and In vitro drug release studies.

The aim of this study was to evaluate the clinical and radiographic outcomes of the All-on-4 technique in fully edentu-lous maxilla using R2GATE software for flapless, computer-guided surgery and immediate loading. Ten adult patients with fully edentulous maxilla, aged between 35 and 60 years, were included in the study between April 2021 and April 2022. The surgical procedure was performed under local anesthesia and followed the All-on-4 approach with immediate loading of implants using a screw-retained provisional acrylic resin prosthesis on the same day. Final prosthesis was de-livered four months after the surgery. Clinical and radiographic outcomes were evaluated at four- and twelve-months post-operation. The study reported a 95% implant survival rate using the All-on-4 technique. The mean marginal bone level was recorded at 0.35 mm and 0.66 mm during the 4 and 12-month follow-up periods, respectively. Fixed provi-sional prosthesis fracture, abutment, and prosthesis screw loosening were the most frequent mechanical complications reported. Within the limitations of this study, the use of computer-guided surgery in the All-on-4 technique seemed to be a promising treatment option with high implant survival rates that may help reduce post-surgical discomfort and me-chanical complications in the rehabilitation of the edentulous maxilla.
