The Burden of the Broken Grid: Modelling improved power-sector reliability to support low carbon development in Nigeria
Authors: Golobish Sarah , Yeganyan Rudolf , Tan Naomi , Cannone Carla , Howells Mark 
Published: April 2023

Abstract
Nigeria has one of the greatest electricity deficits globally and, even in areas connected to the central grid, struggles to provide reliable power across the nation. Frequent system collapses and widespread reliance on diesel generation present a burden for Nigerian households and the economy as a whole. One causal factor in these collapses is capacity inadequacy owing to reduced plant availability as plants are frequently non-operational due to maintenance or other management issues. While this dynamic has been established, it has not yet been explored in energy systems modelling as a potential barrier to meeting Nigeria’s decarbonization goals. Using a combination of OSeMOSYS and FlexTool modelling, this study shows that increasing available capacity decreases loss of load in the energy system. The resulting decrease in backup diesel generation nearly halves total system costs and emissions. Further, Nigeria is unable to meet its 2021 Nationally Determined Contributions (NDCs) without such improvements, indicating that increasing plant availability and reducing diesel generator use must be prioritized in policy to support national implementation of these targets.
Policy Insights:
1) Improved power plant availability can dramatically reduce CO2 emissions from the power sector, even under a business-as-usual scenario. However, increasing the pace of that improvement has a smaller impact on emissions.
2) Nigeria can meet its 2030 Unconditional NDC targets without significant changes to its generation mix if plant availability is improved. Near-term investments in energy efficiency will help to further ensure that targets are met.
3) Nigeria can meet its 2030 Conditional NDC targets with energy efficiency investments and improved plant availability.
4) A 30% cap on variable renewable energy (VRE) coupled with full plant availability is expected to reduce system collapses and lost loads. In the flexibility analysis, runs with full availability were able to reduce lost load even in scenarios with increased VRE.
5) It is not possible to meet long-term decarbonization goals without plant improvement.
Factors Affecting Capital Structure Decisions of Banks: A Systematic Review of Evidence from Commercial Banks of Ethiopia
Authors: Gofe Tesfaye Eresso , Seyoum Arega 
Published: April 2023

Abstract

The present systematic literature review aims to analyze the literature on factors affecting capital structure decisions of commercial banks in Ethiopia to identify the existing gaps and the level of existing research in the field and to provide direction for future research. The review was conducted using 11 relevant and available scholarly studies that were published in any time period, mainly using open search engines and databases because of the shortage of studies for the specified review and lack of access to the known database. Different key words were used to identify the articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework was employed to analyze the research work on capital structure decisions. The inclusion and exclusion criteria were specified in the review protocol. The descriptive analysis was performed based on different parameters to arrive at conclusions. A citation analysis was also performed to recognize impactful authors and papers. The findings revealed that most of the variables of interest explored in the studies contradicted each other and the previous literature variables. The capital structure research studies were conducted by considering few variables, and most of the studies were not cited. The findings regarding the theories supported by factors affecting the capital structure decisions of commercial banks in Ethiopia were contradictory and not justified. The banking literature still doesn't cover the capital structure of banks very much. There is currently a lack of clarity regarding how banks determine their capital structure and what variables affect their corporate financing behaviour. Therefore, it is recommended that the concerned body conduct an in-depth study of the decisions banks make about their capital structure by identifying pertinent elements.

Abstract
Purpose To explore needs, expectations and experiences of asylum-seeking parents and unaccompanied minors on the initial health assessment for children and adolescents, and access to care upon entry in the Netherlands.Methods We conducted five semi-structured focus group discussions with asylum seeking parents and unaccompanied minor refugees, from Syria, Eritrea, Afghanistan and other middle-east and African countries, supported by professional interpreters. To triangulate findings, semi-structured interviews with health care professionals involved in care for refugee children were conducted. Transcripts of focus group discussions were inductively and deductively coded and content analysed, transcripts of interviews were deductively coded and content analysed.Results In total, 31 asylum seeking participants (23 parents of 101 children, 8 minors) and 6 healthcare professionals participated. Parents and minors expressed that upon entry, their needs were met for vaccinations, but not for screening or care for physical and mental health problems. Parents, minors and health professionals emphasized the necessity of appropriate information and education about health, diseases and the health system. Cultural change was mentioned as stressful for parent-child interaction and parental well-being.Conclusion The perspectives of refugee parents and unaccompanied minors revealed opportunities to improve the experience of and access to health care of refugees entering the Netherlands, especially risk-specific screening and more adequate education about health, diseases and the Dutch health care system.
Fast algorithms for coupled Burgers' equations by sharing characteristic curves within BSLM
Authors: Yonghyeon Jeon , Soyoon Bak 
Published: April 2023

Abstract
This paper introduces a new perspective of the traditional view on the velocity of each physical particle in the coupled Burgers' equation in the backward semi-Lagrangian method (BSLM). The proposed methods reduce the number of Cauchy problems to be solved by observing a single virtual characteristic curve with a velocity. This can drastically reduce the computational cost of determining the departure point. And then, we solve the derived system reflected by the single virtual characteristic curve. Moreover, an efficient strategy for the derived linear system of equations is provided. Four examples are tested to demonstrate the adaptability and efficiency of the proposed method. The test results show that the proposed method has third-order accuracy in time and space. In addition, compared with the existing method of solving the problem along two particles with different velocities, we confirm that the proposed method significantly reduces computational cost while maintaining accuracy well.
Factors associated with refractive prediction error after phacotrabeculectomy
Authors: Shin Jung Hye , Kim Seok Hwan , Oh So Hee , Lee Kyoung Min 
Published: April 2023

Abstract
Background: To compare refractive prediction errors between phacotrabeculectomy and phacoemulsification.
Methods: Refractive prediction error was defined as the difference of spherical equivalent between the predicted value using the Barrett Universal II formula and the actual value obtained at postoperative one month. Forty-eight (48) eyes that had undergone uncomplicated phacotrabeculectomy (19 eyes, open-angle glaucoma; 29 eyes, angle-closure glaucoma) were matched with 48 eyes that had undergone uncomplicated phacoemulsification by age, average keratometry value and axial length, and their prediction errors were compared. The factors associated with prediction error were analyzed by multivariable regression analyses.
Results: The absolute prediction error was larger in the phacotrabeculectomy group than in the phacoemulsification group (0.51 ± 0.37 Diopters vs. 0.38 ± 0.22, P=0.033). Larger absolute prediction error was associated with both longer axial length (P=0.010) and higher intraocular pressure difference (P=0.012). A logistic regression analysis showed that hyperopic shift (prediction error>0) was associated with shallower preoperative anterior chamber depth (P=0.024)and larger intraocular pressure difference (P=0.031). In the phacotrabeculectomy group, the prediction error was inversely correlated with axial length: long eyes showed myopic shift and short eyes hyperopic shift (P=0.002).
Conclusions: Intraocular lens (IOL) power calculation might be less accurate in phacotrabeculectomy than in phacoemulsification due to large axial length and anterior chamber depth changes with intraocular pressure lowering. Surgeons therefore should be aware of the possibility of worse refractive outcomes when planning phacotrabeculectomy especially in eyes with high preoperative intraocular pressure, shallow anterior chamber depth, and/or extreme axial length.

Abstract
The metabolic syndrome is a group of factors including central obesity, dyslipidemia, hypertension, and impaired glucose tolerance, with obesity being the most significant aspect. The influence of gene variants involved in hormone synthesis or action could explain the conflicting results when considering the relationship between visfatin plasmatic levels and obesity. However, there is a lack of research on these polymorphisms. This study found that the SNPs for visfatin rs2302559 and rs1215113036 were statistically significantly associated with the metabolic factors at p value 0.001 and odd ratio suggested that there is a great chance of developing the disorder if these variations are present up to at 129.40. Frequency of the mutant alles were to be found in higher in frequency.
Comparison of chemical composition of wet-only and dry-only deposition at Peradeniya in Sri Lanka

Published: April 2023

Abstract
Measurement of pH, conductivity, Na+, NH4+, K+, Mg2+, Ca2+, F−, Cl−, NO3−, SO42−, Pb, Cu, Mn, Al, Zn and Fe of atmospheric deposition samples collected during 2014 September to 2015 March were conducted using acid precipitation sampler (APS) equipped with wet-only and dry-only collectors. Sampler was placed in Peradeniya (Latitude 6.973701, Longitude 79.915256), Kandy District, in Sri Lanka and together 48 samples were collected and analysed. The volume weighted average (VWA) concentrations of the major ionic species present in wet-only precipitation samples were in the order of Na+ > NH4+ > Cl− > SO42− > Ca2+ > NO3− > K+ > Mg2+, while the order for dry-only is Na+ > Cl− > K+ > Ca2+ > SO42− > NH4+ > NO3− > Mg2+ with high concentrations were recorded in dry-only deposition. The lower values for most of the parameters observed in wet depositions are due to the dilution of atmospheric chemical constituents. Neutralization of acidity of dry-only deposition is much more related to CaCO3 than to NH3. The difference between wet and dry depositions of trace elements is likely due to the difference in the size distribution between the elements in atmospheric particles.

Abstract
Soluble Triggering receptor expressed on myeloid cells-1(sTREM-1) is a sensitive marker of inflammation, proven useful in sepsis and infectious diseases prognostication. In search for sensitive biomarkers of response to Pulmonary Tuberculosis (TB) treatment, and treatment endpoint definitions, the current study was designed in patients on TB retreatment regimen. Decline in serum sTREM-1 levels after one and three months of treatment indicated good prognosis with complete cure without relapse. Patients with significant increasing levels in 2nd follow-up (increase > 1000pg/ml), either relapsed or accumulated resistance during treatment, while those with slight increase got cured. Two patients with very high baseline levels (> 10,000pg/ml) died one to two years after treatment completion (one with Diabetes mellitus, other with no known comorbidity). Serum sTREM-1 levels could prognosticate disease outcomes at diagnosis or as early as first month of treatment initiation and prove to be the ideal treatment endpoint marker or raise alarm for sinister outcomes.

Abstract
Purpose Anastomosis of ileocolic resection has been widely performed using a linear stapling device. However, little is known regarding the experience and outcomes of using circular stapling in such anastomosis.Methods We retrospectively reviewed 66 patients who underwent right hemicolectomy, or extended right hemicolectomy from January 1, 2016 to February 1, 2022 at a single center, performed by a single surgeon. The data included both circular stapling and linear stapling ileocolic anastomosis techniques.Results Patients who underwent right hemicolectomy using circular stapling ileocolic anastomosis had a significantly shorter OR time (P = 0.042). Also the length of hospital stay and time of drain removal was significantly shortened (P = 0.005 and 0.023, respectively) compared to linear stapler technique.Conclusion No substantial difference between the two methods of anastomosis was noted. Although the feasibility and safety for performing circular stapling ileocolic anastomosis was assessed, a larger sample size and a longer follow up period are needed to validate the findings.

Authors: Akli Isma , Benhocine Wahiba 
Published: April 2023

Abstract
This paper develops a method for assigning autonomously industrial tasks to adequate agents with suitable capabilities.
Ontology-based knowledge representation method is developed, and experimented for industrial robotic systems. The implementation of the proposed solution requires : (i) the design of the Ontology, (ii) the integration of the Ontology into ROS (Robot Operating System) and (iii) the supplementing of the decision making system with Radio Frequency Identification (RFID) sensorial information.
The decision making Ontology-based system takes decisions. Industrial tasks are assigned to agents depending on workspaces, objects, agents capabilities and tasks to be performed. The Ontology-based task assignment system is validated with introducing RFID sensorial system.
All the instances in the Ontology are detected automatically with RFID sensorial system. The decision making system is able to take decision autonomously depending on the detected entities with the RFID system. The proposed solution is appropriate in industrial applications since modern manufactures require autonomy in decision-making processes.
Note-taking for the win: Doodling does not reduce boredom or mind-wandering, nor enhance attention or retention of lecture material
Authors: Spencer-Mueller Emily Krysten , Fenske Mark J. 
Published: April 2023

Abstract
Doodling and fidgeting—traditionally viewed in educational contexts as markers of inattention and poor classroom behaviour—have more recently been considered as possible routes to improve performance by reducing boredom and its negative impact on memory. However, there is a surprising lack of well-controlled studies examining this possibility, despite the widespread adoption of fidget toys and doodling exercises within classroom settings. Here we report two experiments (total N = 222) that assess the impact of doodling on boredom, attention, mind-wandering, and subsequent recall of auditory information. In Experiment 1, participants first listened to a 15-minute section of a lecture known to induce boredom. Immediately thereafter they were asked to jot down important information from a short voicemail that they listened to while either doodling (adding shading to shapes) or doing nothing in between note-taking. In Experiment 2, participants listened to a 45-minute section of the same lecture under one of four conditions: structured doodling (i.e., shade in shapes), unstructured doodling, note-taking, or listen-only. Thought probes assessed self-perceived levels of state boredom, mind-wandering, and attention throughout the lecture. Across studies, doodling neither reduced boredom or mind-wandering nor increased attention or retention of information compared to other conditions. In contrast, attention and test performance were highest (and boredom and mind-wandering lowest) for those focused solely on note-taking.

Published: April 2023

Abstract
Background: Deep endometriosis (DE) is usually associated with severe pelvic pain, dysmenorrhea and other pain symptoms and can be more aggressive than other types of endometriosis, even leading to irreversible severe complications such as complete unilateral loss of renal function. Previous data showed that up to 30% of patients with urinary tract DE may have reduced kidney function at the time of diagnosis although the real prevalence is unknown. All doctors and health caregivers involved in endometriosis diagnosis and treatment should be aware of this complication and should suspect and avoid this rare, albeit severe, form of the disease. We aimed to describe the clinical and radiologic characteristics of deep endometriosis (DE) patients diagnosed with irreversible unilateral loss of renal function due to unilateral ureteral stenosis and evaluate risk factors for developing this loss.
Methods: Retrospective cohort study including 436 patients who underwent laparoscopic DE surgery. We evaluated two groups of patients according to preserved (Non-Renal Loss Group; n=421) or irreversible unilateral damaged renal function (Renal Loss Group; n=15).
Preoperative epidemiologic variables, clinical characteristics, radiologic findings and surgical treatments of all patients were collected.
Results: The Renal Loss Group had a higher infertility rate and a higher proportion of asymptomatic patients. The following radiological variables showed statistically significant differences between the two groups: mean endometrioma diameter, the presence of intestinal DE and negative sliding sign. Multivariate analysis showed that infertility, being asymptomatic, having intestinal DE or torus uterinus/uterosacral ligament DE and a negative sliding sign significantly increased the risk of loss of renal function.
Conclusions: Some clinical and radiological variables may help identify patients with DE at high risk of presenting loss of renal function due to ureteral stenosis. Therefore, among these patients, severe urinary tract obstruction should be specifically ruled out.

Abstract
Purpose Tumor size, number, alpha-fetoprotein (AFP), and cirrhosis are well-known prognostic factors in patients with hepatocellular carcinoma (HCC) undergoing liver resection (LR). We aimed to develop a preoperative model to predict overall survival (OS) in these patients based on these variables.Methods Patients who underwent LR for Barcelona Clinic Liver Cancer (BCLC) stage 0, A, or B HCC were enrolled.Results Among 743 enrolled patients, 193 (26.0%) patients had a low tumor burden score (TBS) (< 2.6), 474 (63.8%) had a medium TBS (2.6–7.9), and 75 (10.1%) had a high TBS (> 7.9). Multivariate analysis showed that TBS (low: referent; medium: HR = 2.91; 95% CI: 1.62–5.24; p < 0.001; high, HR = 7.73; 95% CI: 3.90–15.3; p < 0.001), AFP (< 400 ng/mL: referent; ≧400 ng/mL: HR = 1.64, 95% CI: 1.10 − 2.45, p = 0.015), and cirrhosis (absence: referent; presence: HR = 1.88, 95% CI: 1.30–2.73, p < 0.001) were associated with OS. A simplified risk score was superior to BCLC in concordance index (0.688 vs. 0.617), Akaike information criteria (1438 vs. 1466), and homogeneity (57.5 vs. 31.6). It also further stratified patients within each BCLC group relative to five-year OS: BCLC 0: very low = 95%, and low = 78%; BCLC A: very low = 93%, low = 79%, medium = 63%, and high = 52%; and BCLC B: low = 82%, medium = 38%, and high = 21%.Conclusion We have developed a simple preoperative model that performs better in predicting OS than the BCLC system.

Abstract
The high body fat percentage incresed risk of cardiovascular and metabolic. To evaluate the influence of body fat on inflammatory markers and cardiometabolic risk factors in female adolescents. Cross-sectional study with 555 female adolescents, aged 10 to 19 years. The Body Mass Index (BMI) was calculated. Body fat percentage was obtained by dual-energy X-ray absorptiometry (DEXA) equipment. Were evaluated systolic and diastolic blood pressures, fasting glucose levels, insulin, lipid profile, uric acid, and inflammatory markers (Interleukin 6 - IL-6, Interleukin 10 - IL-10, high-sensitivity C Reactive Protein – hs-CRP, Tumor Necrosis Factor - TNF-α, Leptin, and Tumor Necrosis Factor - TNF-α). The Kolmogorov-Smirnov test was performed to verify the distribution of the variables, and the Pearson and Spearman correlation tests were used according to the characteristics of the variables. Linear regression analyses were performed. A statistical significance level of 5% was adopted. Increased body fat in adolescent girls relates to increased values of blood pressure, lipid profile, insulin, uric acid, leptin and IL-6. The increasing one percent body fat increases uric acid by 1.22 mg/dL and leptin by 0.0005 pg/mL, suggesting that for these two markers, eutrophic adolescents with high percent body fat show similar behavior as obese adolescents (with high BMI and body fat). The highlight the need to assess body composition in adolescents to identify those with higher fat percentage, since, even with normal weight, they may present increased risk of developing cardiovascular and metabolic complications at this stage of life, which may be maintained or worsened in adulthood.
