A Female-Agency Perspective on Female Political Leadership in Africa

A paucity of research studies explore agency utilised by female political leaders to navigate spaces predominantly occupied by male counterparts. The main objective of the study was to explore femaleagency fostering the ascension of women to leadership positions in Kenya, an East African country. This study examined the lived experiences of Kenyan female political leaders using a qualitative exploratory approach implemented by means of interviews. Findings indicated that female-agency with specific reference to political leadership centres on eight strategies, inter alia, formal educational attainment, utilising formal educational leadership opportunities, personal development and lifelong learning, social support systems, mentorship, challenging gender roles and stereotypes, leadership traits and tactics. Female participation in leadership remains essential to ensure balanced decision-making and public outcomes. However, African women remain under-represented in leadership positions, in particular within the political sphere. Male dominance and gender stereotypes have been identified as significant obstacles hindering women from accessing leadership positions. Strategies to improve female participation in leadership positions with specific reference to the political sphere should be based on empirical findings. Moreover, female-agency research could be perceived as a strategy to challenge gender stereotyping.
Ordering Policy of Two-Stage Newsvendor Model for Fresh Retailer under RFID Investment

Fresh products have a strong dependence on time and a large loss rate in the circulation process. Applying RFID technology to the supply chain of fresh products, through the real-time tracking technology, can not only reduce the products’ time dependence but also realize the second order within the whole sales period. (is paper takes a two-echelon fresh supply chain of a single fresh retailer as the research object, constructs a two-stage Newsvendor model with or without RFID technology, compares the difference in profits, and provides decision-making reference for fresh retailers whether to invest in RFID or not.
Phase I Clinical Trial of Oral Curcumin: Biomarkers of Systemic Activity and Compliance

Curcumin, a polyphenolic antioxidant derived from a dietary spice, exhibits anticancer activity in rodents and in humans. Its efficacy appears to be related to induction of glutathione S-transferase enzymes, inhibition of prostaglandin E2 (PGE2) production, or suppression of oxidative DNA adduct (M1G) formation. We designed a dose-escalation study to explore the pharmacology of curcumin in humans. Fifteen patients with advanced colorectal cancer refractory to standard chemotherapies consumed capsules compatible with curcumin doses between 0.45 and 3.6 g daily for up to 4 months. Levels of curcumin and its metabolites in plasma, urine, and feces were analyzed by highpressure liquid chromatography and mass spectrometry. Three biomarkers of the potential activity of curcumin were translated from preclinical models and measured in patient blood leukocytes: glutathione S-transferase activity, levels of M1G, and PGE2 production induced ex vivo. Dose-limiting toxicity was not observed. Curcumin and its glucuronide and sulfate metabolites were detected in plasma in the 10 nmol/L range and in urine. A daily dose of 3.6 g curcumin engendered 62% and 57% decreases in inducible PGE2 production in blood samples taken 1 hour after dose on days 1 and 29, respectively, of treatment compared with levels observed immediately predose (P < 0.05). A daily oral dose of 3.6 g of curcumin is advocated for Phase II evaluation in the prevention or treatment of cancers outside the gastrointestinal tract. PGE2 production in blood and target tissue may indicate biological activity. Levels of curcumin and its metabolites in the urine can be used to assess general compliance.
On the Role of Soot and Radiative Heat Flux for Flame Spread Along Solid Fuels

This study presents the influence of O2/N2 oxidizer blends on soot formation and radiative heat flux (RHF) in PMMA-Air slab burner experiments. RHF is measured using two-color pyrometry along with flame reconstruction techniques. Far-field O2 concentrations are varied in the range of 17−28% in experiments and the overall flame temperatures, soot volume fraction (SVF), and RHF are found to increase. These observations are further analyzed using numerical solutions to diffusion flamelets. A semi-empirical two-equation soot formation model is coupled with the flamelet solver along with a fully-coupled discrete ordinates radiation solver. O2 concentrations are varied from 15−100%. Flame temperatures are found to increase with O2 concentrations. Soot volume fraction initially increases, peaking at 45% O2 concentration and then decreases with further increase in O2 concentration. Regardless of soot behavior, RHF from flamelets is found to increase with O2 concentrations. The field averaged RHF from slab burner experiments are found to be in very good agreement with the RHF from 1D flames at low O2 concentrations. Furthermore, the RHF values are also compared to Tewarson et al. [1] values extrapolated using radiation corrected Spalding B-number equation and are found to be consistent. These results enable one to correlate RHF predictions from flamelets to those observed in multi-dimensional flame spread experiments.
Health Visualizations at Home: Who Sees What Where

We conducted a qualitative study pilot to gather requirements for integrating health visualizations at home. We focused on finding dynamics between (1) people : who the visualizations are made for, and others who will see them; (2) visualization : what visual representations people expect for their homes; and (3) location : where people expect to find the visualizations. We describe our study methodology and the results. We found hints of concepts for consideration such as (1) privacy can be derived from visualization style, (2) visualizations can be installed at high traffic locations but data sensitivity should be considered, and (3) location of related tools at home can influence where visualizations should be located.
Multispectral Imaging and the Digitization of the Dead Sea Scrolls

Papers presented at the Book and Paper Group Session, AIC’s 46th Annual Meeting, May 29-June 2, 2018, Houston, Texas caves with scrolls over a period of eight years. The excavated material was brought to the Rockefeller Museum in Jerusalem, where it was studied by an international team of biblical scholars. All together, these excavations yielded thousands of fragments comprising around 900 manuscripts spanning a period of time from the third century BCE to the first century CE. In addition to the material found in the Qumran caves, the IAA’s collection includes manuscripts from six other locations in the Judean Desert dating from the fourth century BCE to the seventh century CE. Around 80% of the collection is parchment while the remaining 20% is papyrus. The original scholars, working on the world’s largest jigsaw puzzle, arranged the thousands of fragments of varying sizes into over 1,500 glass plates (fig. 1).
COMPARATIVO DA CINÉTICA DE DECOMPOSIÇÃO TÉRMICA DA PALHA DE CANA-DE-AÇÚCAR EM ATMOSFERA OXIDANTE E INERTE

RESUMO – Este trabalho teve como objetivo estudar a cinética de decomposição térmica da palha de cana-de-açúcar através da técnica de termogravimetria. As condições aplicadas foram: partículas de 510 μm, atmosfera de ar sintético e taxa de aquecimento de 10 oC/min. A análise cinética foi realizada aplicando o modelo de reações paralelas e independentes considerando três principais componentes da biomassa (celulose, hemicelulose e lignina). Seis reações foram assumidas, sendo três relacionadas à devolatilização de cada componente, e outras três à combustão do carvão remanescente. Os resultados obtidos a partir da modelagem ajustaram de maneira bastante satisfatória aos dados experimentais (R2=0,9848). Os parâmetros cinéticos obtidos em atmosfera oxidante foram comparados com dados de literatura em atmosfera inerte, sendo maiores devido ao aumento da temperatura causado pelas reações de oxidação dos voláteis liberados.

Influence of Emitter Structure on Its Hydraulic Performance Based on the Vortex

The rectangular labyrinth emitter is taken as the study object in this article, as we added internal teeth to vortex-free and vortex areas in its lateral channel or lengthened the vertical channel, to change the channel structure. Using the computational fluid dynamics (CFD) method simulates the water flow field, to get the relationship between flow rate and pressure, and the vortexes distribution in channel. The aim of this study is to explore the reasons for the influence of structural change on hydraulic performance of the emitter through the analysis of vortex intensity and its distribution from the perspective of the vortex. The results show that the relative error of simulated results and experimental data was 1.02–2.11%. Adding internal teeth to vortex-free areas in lateral channel can improve hydraulic performance of the emitter; adding them to vortex areas can reduce it. The increase in vortex number and intensity in flow field is the internal reason for the improvement of the emitter’s hydraulic performance. The channel structure changes promote the formation of a larger velocity gradient, and the increase in the velocity gradient in flow field exacerbates vortex formation. Changing channel structure to improve the emitter’s hydraulic performance can promote an increase in the number and intensity of vortexes in the channel.
Navigation Control of an Autonomous Mobile Guide Robot

—Designing and manufacturing of an intelligent, autonomous guide robot, its navigation in indoor environments with the user communication, are the principal objectives of this work. The presented behavior-based maples navigation control architecture performs the robot localization, obstacle avoidance, wall following, and path planning to steer it from any initial pose to any assigned location, by employing the onboard sensors. The research aims to reveal the pros and cons of the behavior-based maples navigation against map-based navigation control. Also a graphical interface is designed and presented to interact with the user. In order to fix the encountered data transmission problems between the electrical hardware, some proper techniques are presented. On the other hand, in addition to some electrical and mechanical modifications, two control techniques are proposed to improve the wheels skidding, and the crooked drive mechanical deficiencies.
Virtual Bone Shape Aging

We use deep learning to age knee bone surfaces four years. We propose to encode an MRI-based bone surface in a spherical coordinate format, and use these spherical maps to predict shape changes in a 48 months time frame, in subjects with and without osteoarthritis. The experiments show that a 2D V-Net can predict bone surface shape with a mean absolute error of about 1 mm. Our code is available here.
Visualization of 4D-PET/CT, Target Volumes and Dose Distribution: Applications in Radiotherapy Planning

In radiation treatment (RT) planning medical doctors need to consider a variety of information sources for anatomical and functional target volume delineation. The validation and inspection of the defined target volumes and the resulting RT plan is a complex task, especially in the presence of moving target areas as it is the case for tumors of the chest and the upper abdomen. A 4D-PET/CT visualization system may become a helpful tool for validating RT plans. We define major requirements such a visualization system should fulfill to provide medical doctors with the necessary visual information to validate tumor delineations, and review the dose distribution of a RT plan. We present an implementation of such a system, and present qualitative results of its applications for a lung cancer patient.
Using the Diaphragm as a Tracking Surrogate in CyberKnife Synchrony Treatment

Background In this study, we assessed the usefulness of diaphragm surrogate tracking in the design of a respiratory model for CyberKnife Synchrony treatment of lung tumors. Material/Methods Twenty-four patients with lung cancer who underwent stereotactic body radiotherapy with CyberKnife between April and November 2019 were enrolled. Simulation plans for each patient were designed using Xsight lung tracking (XLT) and diaphragm tracking (DT) methods, and tumor visualization tests were performed. The offset consistency at each respiratory phase was analyzed. The relative distance along the alignment center of the superior-inferior (SI) axis in the 2 projections (dxAB), uncertainty (%), and average standard error (AvgStdErr)/maximum standard error (MAXStdErr) were also analyzed. Results Bland-Altman analyses revealed that the average differences±standard deviation (SD) between XLT and DT tracking methods were 0.4±2.9 mm, 0.3±4.35 mm, and -1.8±6.8 mm for the SI, left-right (LR), and anterior-posterior (AP) directions, respectively. These results indicated high consistency in the SI and LR directions and poor consistency in the AP direction. Uncertainty differed significantly between XLT and DT (22.813±5.721% vs 9.384±3.799%; t=−5.236; P=0.0008), but we found no significant differences in dxAB, AvgStdErr, or MAXStdErr. Conclusions In the majority of cases, motion tracking by XLT and DT was consistent and synchronized in the SI directions, but not in the LR and AP directions. With a boundary margin of 0.3±4.35 mm and 1.8±6.8 mm for the LR and AP directions, DT may contribute to better implementation of CyberKnife Synchrony treatment in patients with lung tumors near the diaphragm that cannot be seen in tumor visualization tests.
Work-Related Stressors, Coping Strategies: Its Relation to Job Performance and Perceived Organizational Support among Critical Care Nurses

Context: Work-related stressors are a world phenomenon. It results in a variety of diseases or disorders in terms of physical, psychological, and behavioral. It is commonly associated with jobs that require a lot of direct interactions with clients such as nurses that could affect nurses' job performance and cause high costs for the hospital. A problem needs a sense of support from the organization. Aim: The present study was aimed to assess work-related stressors, coping strategies, and its relation to job performance and perceived organizational support among critical care nurses. Methods: The study was conducted at Critical Care Units at Benha University Hospital. Subjects: All staff nurses (235) who working at Critical Care Units at Benha University Hospital. A descriptive correlational design was utilized. Four tools were employed in this study, Work-Related Stressors Assessment Questionnaire, The Coping and Adaptation Processing Scale (CAPS), Nurses' job Performance evaluation (observational checklist), and Perceived Organizational Support Questionnaire. Results: This study's findings indicated that nearly three-fifths (60.4%) of staff nurses had a moderate level of the work-related stressor. Also, about two-thirds (63.90%) of them had a high level of coping strategies and, about two-thirds (65.90%) of staff nurses had a moderate level of perception of organizational support and nearly half (49.80%) of nurses had a low level of performance. Conclusions: The present study concluded that nurses reported a moderate perception level regarding work-related stressors and organizational support. While nurses reported a high level of coping strategies and a low level of job performance, there was a statistically significant negative correlation between the total score of work-related stressors and nurses' job performance. There was a statistically significant positive correlation between coping strategies and nurses' job performance. A statistically significant positive correlation was revealed between total perceived organizational support and total level of nurses' job performance. The study recommended that hospital administration organize seminars and workshops for nurses targeted at specific sources of stress like conflict resolution, workload, and time management. Efforts to improve nurses' performance must be performed, aiming to increase nurses' ability to complete tasks assigned to them through education and training.
COMPARATIVE EFFECT OF ANTIDIABETIC DRUG SITAGLIPTIN WITH SZYGIUM CUMINI ON PANCREATIC ACTIVITY

Many oral hypoglycemic drugs are available for the treatment of diabetes mellitus. Along with other hypoglycemics dipeptidylpeptidase-4 inhibitors that is Sitagliptins are one of the new drugs which are used for the treatment of diabetes. The DPP4 inhibitors are gliptins that are used orally. The mechanism of DPP-4 inhibitors is to increase incretin levels (GLP-1 and GIP) which inhibit glucagon release, which in turn increases insulin secretion. Sitagliptin may cause pancreatitis and infections so the combination of Sitagliptin and S. cumini can be helpful to reduce dose of Sitagliptin and can increase safety and efficacy of Sitagliptin. The seeds of Jamun used as antidiabetic agent. Szygium cumini belongs to family Myrtaceae. It is commonly known as Jambol fruit and locally as Jamun. Results showed that combination has synergistic hypoglycemic activity. Sitagliptin not produced severe pancreatitis and with the combination it gives more improved activity. C-reactive protein and serum lipase levels not altered significantly. Serum amylase level reduced with combination so it can increase protection against pancreatitis.
A Novel Substrate-Inspired Fluorescence-Based Albumin Detection Improves Assessment of Clinical Outcomes in Hemodialysis Patients Receiving a Nursing Nutrition Intervention

Background Albumin level does not precisely reflect nutritional status. We aimed to investigate the impact of a nutrition intervention on hemodialysis patients by use of fluorescence-based plasma albumin (FPA) detection. Material/Methods Eighty patients underwent maintenance hemodialysis for more than half a year and had a mean albumin <3.5 g/dL for over 3 months. The subjects were randomly divided into either a Control Group (CG) or an Intervention Group (IG). The IG received nutritional supplementation, and the CG group received routine nutritional support for 12 months. FPA and plasma albumin (PA) concentrations were measured. The fluorescence probe 1,3-Dichloro-7-hydroxy-9,9-dimethyl-2(9H)-acridone methyl biphenyl benzoate was used in FPA detection. Quality of life was estimated using WHOQOL-BREF (Quality of Life Scale developed through the World Health Organization), the 36-Item Short-Form Survey (SF-36), and the 6-minute walking test (6MWT). Results After a 6-month and a 12-month intervention, PA and FPA concentrations increased, and the increase in FPA concentration was higher than that of PA in the IG group (P<0.05). Comparatively, the parameters of quality of life and 6MWT were improved in the IG group (P<0.05) but there were only minor changes in the CG group (P>0.05). There is an obvious association between the changes in FPA concentration and the parameters of quality of life and 6MWT but not PA. Conclusions Use of the fluorescence probe improves the detection sensitivity of plasma albumin and provides a potential method to assess clinical outcomes in hemodialysis patients.
Building Semantic Information Extraction Based on Full Convolution Neural Network and Parameter Transfer

Aiming at the problem that the generalization ability of deep convolution neural network model is limited, this paper extracted the semantic information of buildings in different regions by combining the transfer learning method. Taking the Massachusetts aerial image building data set as an example, the layer depth structure of Segnet network model is improved, and a new model is trained by migrating the parameters of the improved model and combining with a small number of Guilin building image data samples. The extraction results were analyzed and compared. The results show that, by transferring the parameters of the trained model, the Kappa coefficient and F1 score of buildings in Guilin area reached about 0.8.
Simulation Research on the Post-arc Dielectric Recovery Characteristics of Multi-break Vacuum Circuit Breakers

The dielectric recovery characteristics are very important for the successful interruption of the vacuum circuit breaker. In order to explore the influence of the post-arc dielectric recovery characteristics of the multi-break vacuum circuit breaker on its breaking, this article establishes a simulation model of the multi-break vacuum circuit breaker and a 750kV short line fault simulation circuit in MATLAB. By adjusting the dielectric recovery characteristics of different breaks, the critical dielectric recovery rate (The minimum dielectric recovery rate of the break when the circuit breaker does not break down) under different conditions is finally obtained. In addition, the influence of the equalizing capacitor on the critical recovery rate is also explored. It is found that the smaller the grading capacitance, the greater the voltage of the break, and the greater the critical dielectric recovery rate.
