Effect of Different Time for Spathes Bagging on Fruit Set, Yield and Quality of Barhi and Majdool Date Palm under Sudan Climatic Conditions

Bagging spathes time is one of the most important factor, which affect fruit set, yield and physicochemical characteristics of date palm cv. Barhi and Majdool date palm under Sudan condition were assessed under agro climatic conditions of Sudan during 2015, 2016 and 2017 growing seasons. Treatments consisted of five varied bagging timings using kraft paper i.e., at spathe bagging 15, 30, 45 and 60 days after pollination compared with control (unbagging). Data were collected for fruit set (%), fruit drop (%), fruit yield (kg/ palm) and some of physicochemical quality parameters. Results revealed that bagging times affected all the parameters significantly. Maximum fruit set and fruit yield and best fruit quality and minimum fruit drop of two cultivars from bagging at spathes 30 days after pollination. Fruit quality improved the overall fruit physicochemical quality characteristics with maximum fruit length, fruit width, fruit volume, fruit weight, total soluble solids, total acidity and total sugars. This study proved that bagging spathes after pollination 30days was more effective for optimum fruit set and economic yield and best fruit quality.
A deep water and nearshore wave height calibration of the ECOWAVES hindcasting database

Significant wave height (SWH) in shallow waters is assessed by generating two wave hindcasts; the first uses ERA-Interim wind fields and the second one from ERA5 to quantify the improvement of the ERA5 surface winds on the SWH representativeness, both in deep and shallow waters along the Chilean coastline. Additionally, wind field predictions from the Global Forecast System (GFS) were used to assess the representativeness of shallow waters. Oceanographic buoys were used to validate SWH in deep waters, while Acoustic Doppler Current Profiler (ADCPs) was equipped to measure waves in shallow waters. Energy spectrums coupling Wavewatch III and Simulating Waves Nearshore (SWAN) models were transferred to evaluate the performance of shallow water simulations. In general, the SWH from both wave hindcasts showed good performance. Nonetheless, those forced by ERA5 presented a better qualitative comparison of sea state temporal variability, which increased the correlation coefficients (>0.9), coefficients of determination (>0.8), and minor errors (RMSE, MAE, and BIAS) compared to oceanographic buoys and ADCPs. Additionally, in simulations forced by GFS, the temporal variability of the waves in shallow waters was successfully reproduced. Nevertheless, an increase in the RMSE, MAE, and BIAS error was statistically verified compared to ERA-Interim and ERA 5.
Determinant Analysis of Company Debt Policy with Vector Error Correction Model Approach

Purpose- This study uses a VECM model that aims to see the short-run and long-term effects of managerial ownership, sales growth, free cash flow, and asset structure against debt policy. Vector Error Correction Model (VECM) is a model that can be used for time series data that is not stationary but has a cointegration relationship where in the model included stationary exogenous variables as additional regressors. Research Method- The sample used in this research is quantitative data with a purposive sampling technique. Based on the criteria, the number of samples collected is 32 samples in the period 2013-2021.The data analysis techniques in this study use Vector Error Correlation Model (VECM) analysis, several stages that researchers must go through before determining the right model, namely data stationarity test, optimal lag length test, co-integration test, VAR model stability test, granger causality analysis, VAR/VECM empirical model, Impulse Response Function analysis and Variance Decomposition analysis. Findings- The results of the analysis show that in the short term only sales growth and asset structure have a significant influence on debt policy. Meanwhile, in the long-term free cash flow, asset structure and sales growth have a significant influence on debt policy, while managerial ownership has an insignificant effect on debt policy. Implication- For the company should reduce the proportion of funding from debt in the implementation of its operations so as to reduce financial distress, because funding from corporate debt causes financial distress and agency costs greater than tax savings from debt interest expense, as a result of which the company is very vulnerable to economic turmoil. For creditors who provide sources of debt funding, pay more attention to aspects of the company's asset structure to be used as collateral for debt, because the company usually uses loan funds for high-risk projects. For investors should take deeper considerations to invest in companies that have large free cash flow because companies that have large free cash flow tend to show good cash flow for the future.
The Effect of Heartfulness Meditation Program on Burnout and Satisfaction With Life Among Accounting Professionals

Background Accounting professionals experience a stressful working environment with previous studies demonstrating a high prevalence of burnout. Meditation-based interventions have a potential role in decreasing burnout and improving satisfaction with life. However, the benefits of Heartfulness meditation intervention have not been demonstrated among accounting professionals. Objective To evaluate the effects of an 8-week Heartfulness Meditation program on burnout and satisfaction with life in chartered accountants. Methods The study was a prospective cohort analysis comparing burnout and satisfaction with life outcomes among accounting professionals who either self-selected to participate in the Heartfulness Meditation Program (intervention group) or with no particular intervention (control group). Maslach Burnout Inventory (MBI) and Satisfaction with Life Scale (SWLS) scores were collected at baseline and at the end of the study period. Results Two hundred and six participants completed the study. Participants in the intervention group (n = 107) experienced statistically significant improvement in MBI emotional exhaustion from 2.17 to 1.75 (P = .00) and overall MBI score decreased from 2.99 to 2.83 (P = .020). Participants in the control group (n = 99) experienced statistically significant improvement for emotional exhaustion only, from 1.82 to 1.52 (P = .009). Further, participants in the intervention group demonstrated statistically significant improvement with SWLS from 4.90 to 5.17 (P = .005). While participants in the intervention group experienced higher levels of decline (19.55%) compared to the control group (16.41%) for emotional exhaustion, it was not statistically significant. Conclusion The current study is one of the first attempts of a Heartfulness meditation intervention to reduce burnout and improve satisfaction with life among accounting professionals. Both the intervention group and the control group showed an improvement of emotional exhaustion. The statistically significant improvements observed in the overall MBI and SWLS outcomes in the intervention group suggest an online Heartfulness meditation program could serve as a potential tool for reducing burnout and improving satisfaction among accounting professionals.
Efficacy and Tolerability of Two Different Low-Volume Split-Dose Polyethylene Glycol Electrolytes Solution Bowel Preparation for Morning Colonoscopy

Methods A total of 120 patients were randomized to receive either the control group (n = 64) or the experimental group (n = 65). Patients in the control group adopted the low-volume split-dose regimen one, and patients in the experimental group adopted the low-volume split-dose regimen two. Those randomized to regimen one were instructed to take 0.75 L PEG two hours after dinner the day before the colonoscopy and 1.5 L PEG 4 hours before the colonoscopy. Patients assigned to regimen two were invited to consume 1.5 L PEG two hours after dinner the day before the colonoscopy and 0.75 L PEG 4 hours before the colonoscopy. The quality of bowel preparation, rated according to a Boston Bowel Preparation Scale (BBPS), represented the primary outcome measure. Tolerability, satisfaction, and lesions detection rated were secondary outcomes. Results There was no significant difference between the transverse colon and right colon scores between the two groups (P > 0.05). The low-volume split-dose regimen two showed a higher success rate for cleansing of the right colon and overall colon (P < 0.05). For the comparison of the patients' bowel tolerance, there were no statistical differences between the two groups regarding thirst, abdominal pain or abdominal discomfort, abdominal distension, dizziness or headache, anal discomfort, and sleep disturbance (P > 0.05). However, regimen two had significantly less nausea, vomiting, and fatigue than regimen one (24.62% vs. 42.19%, P=0.034; 10.77% vs. 25.00%, P=0.035; 6.15% vs. 21.88%, P=0.010, respectively). Patient-reported satisfaction and willingness to repeat the bowel preparation were significantly higher for low-volume split-dose regimen two than for low-volume split-dose regimen one (P=0.011; P=0.015). Conclusions In early morning colonoscopies, the bowel-cleansing efficacy and patient tolerability of low-volume split-dose regimen two were superior to low-volume split-dose regimen one.
Toward an Institutional Analytics Agenda for Addressing Student Dropout in Higher Education: An Academic Stakeholders' Perspective

Although the number of students in higher education institutions (HEIs) has increased over the past two decades, it is far from assured that all students will gain an academic degree. To that end, institutional analytics (IA) can offer insights to support strategic planning with the aim of reducing dropout and therefore of minimizing its negative impact (e.g., on students, academic stakeholders, and institutions). However, it is not clear how institutional stakeholders can integrate IA in their practice to overcome academic-related issues and to offer support to students who struggle to achieve their academic goals. To address this gap, we conducted focus groups with 13 institutional stakeholders of an Estonian university. By analyzing the focus group data, we identified three main categories of factors influencing dropout from the perspective of institutional stakeholders: (1) institutional experience, (2) educational goals, and (3) personal aspects. We discuss our findings from an institutional perspective with the aim of reflecting on institutional processes, organizational structures, and facilitatory roles in the context of dropout in higher education (HE). We argue that IA can provide insights into students’ institutional experience, educational goals, and personal aspects to further support decision-making on the institutional level. We envision our findings contributing to a participatory agenda for the design, implementation, and integration of IA solutions focusing on addressing dropout in HE.
Vanishing of the first $(\sigma,\tau)$-cohomology group of triangular Banach algebras

In this paper, we define the first topological $(\sigma,\tau)$-cohomology group and examine vanishing of the first $(\sigma,\tau)$-cohomology groups of certain triangular Banach algebras. We apply our results to study the $(\sigma,\tau)$-weak amenability and $(\sigma,\tau)$-amenability of triangular Banach algebras.
NUMERICAL EXPERIMENTS ON SELF-CONTROL OF WALL TURBULENCE BY SURFACE MORPHOLOGY

The self-control of turbulence in wall-bounded flows is considered in pipes of non-circular cross-sections which act to restructure fluctuations towards the limiting state where these must be entirely suppressed. Direct numerical simulations of turbulence in pipes of polygon-shaped cross-sections with straight and profiled sides were performed at a Reynolds number Reτ ≃ 300 based on the wall shear velocity and the hydraulic diameter. Using the lattice Boltzmann numerical algorithm, turbulence was resolved with up to about 540×106 grid points (8192×257×256 in the x1, x2 and x3 directions). The first exploratory results show a decrease in the viscous drag around corners, resulting in a reduction of the skinfriction coefficient compared with expectations based on the well-established concept of hydraulic diameter and the use of the Blasius correlation. These findings support the conjecture that turbulence might be completely suppressed if the pipe cross-section is a polygon consisting of a sufficient number of profiled sides of the same length which intersect at rightangles at the corners.
Distributed Consensus Control of Networked Robotic Systems With Dynamic Leader Under Time-Varying Delays and Denial-of-Service Attacks

Consensus of multi-agent systems has a wide range of applications, such as coordination, cooperative transportation, and synchronization. This study investigates consensus control in the task space of multi-robotic systems modeled using Euler-Lagrange equations with a moving leading under time-varying delays and denial-of-service (DoS) attacks, respectively. Two control algorithms are studied when networked robotic systems are interconnected over directed spanning trees with a constant-velocity leader as the root. First, we use the Lyapunov-Razumikhin theorem to address a condition of the maximum time delay for nonuniform time-delay communication, thereby ensuring asymptotic tracking of the network. Second, we propose a novel resilient control framework to deal with DoS attacks. Note that designing the control algorithm for DoS attacks is difficult because the attacks cause signal discontinuity. The proposed resilient controller can release the DoS duration condition, which is a common requirement in many related works. It is verified that the consensus errors converge to the origin under the proposed control frameworks. We present experimental results to demonstrate the effectiveness of the proposed controllers.
INFLUENCE OF ROASTING AND STORAGE CONDITIONS ON BIOCHEMICAL CONSTITUENTS OF ARABICA COFFEE BEANS

The changes of biochemical compositions of arabica coffee beans were determined before and after roasting and storage. The caffeine content increased due to storage coffee beans under atmospheric air or nitrogen gas. The roasting of beans at 180°C for 15, 20 and 30 min to produce light, medium and dark coffee increased caffeine content in all samples. It was found that trigonelline content decreased as a result of both roasting and storage. The effect of roasting and storage of coffee beans for 3 and 6 months revealed a presence of new fatty acids as a degradable product. The beans stored under air or nitrogen, short chain fatty acids were appeared and linoleic was decreased, while palmitic and stearic were increased. The remarkable changes in the fatty acid composition showed especially when stored under atmospheric air, mean while storage under nitrogen resulted in less degradation in the unsaturated fatty acids.
Descending Central Series of Free Pro-p-Groups

In this thesis, we study the first three cohomology groups of the quotients of the descending central series of a free pro-p-group. We analyse the Lyndon-HochschildSerre spectral sequence up to degree three and develop what we believe is a new technique to compute the third cohomology group. Using Fox-Calculus we express the cocycles of a finite p-group G with coefficients on a certain module M as the kernel of a matrix composed by the derivatives of the relations of a minimal presentation for G. We also show a relation between free groups and finite fields, this is a new exiting recent development. We do this by showing the explicit bijection between basic commutators and the irreducible polynomials over a certain finite field.
Adaptive Optics Imaging to Analyze the Photoreceptor Layer Reconstitution in Acute Syphilitic Posterior Placoid Chorioretinopathy

Acute posterior syphilitic placoid chorioretinopathy (ASPPC) is a rare ocular manifestation of syphilis characterized by outer retinal layers involvement and drop in visual acuity. The current work documents outer retinal layer involvement in this pathology and their reconstitution with treatment by means of adaptive optics (AO). Three eyes of two patients together with four controls eyes were included in the study. Patients underwent optical coherence tomography (OCT) and OCT angiography (OCTA) scan centered on fovea, where vessel density (VD) and vessel perfusion (VP) were calculated. AO images centered on fovea were acquired and cone density (CD) and cone spacing (CS) were measured and compared to control group. Multimodal imaging was performed at presentation, at 10 days, and at 2-month follow-up. All eyes improved in visual acuity, with reconstitution in outer retinal layers at 2-month follow-up. Overall choriocapillary layer VD and VP improved. AO imaging was able to identify outer retinal alterations at presentation and at follow-ups, with improvement in tissue architecture. CD and CS was respectively lower and greater than controls at all follow-ups and improved within patients at the 2-month follow-up. In conclusion, AO was able to document outer retinal alterations in ASPPC at presentation and improvement over the follow-up, representing a tool to study photoreceptor layer involvement in this pathology.
Potential Effects of Different Dietary Copper Sources to Improve Productive Performance, Plasma Biochemical Parameters and Oxidative Response Activities of Broiler Chickens

This investigation was established to assess the effect of dietary different copper sources and levels supplementation on growth performance, plasma biochemical parameters and antioxidant activities of broiler chickens. Four hundred and twenty-one-day-old chicks (Ross 308) were randomly allocated into 7 experimental treatment (n= 60 birds per each). At the end of the experiment, results obtained revealed that birds fed basal diet with inorganic or organic Cu had significantly (P < 0.05) better live body weight, weight gain and feed conversion ratio, while feed intake was reduced comparison with control group. Chicks supplemented with organic CuNo3 significantly (P < 0.05) improved growth performance s compared with the other groups. Considerable reductions in plasma total cholesterol and triglyceride, high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDL-C) were detected in the group that fed diet with 125 mg / kg diet Cu in comparison with other diets. Plasma glutathione (GPX), superoxide dismutase (SOD) and total antioxidant activity (T-AOC) were significantly enhanced with Cu-supplemented diets, while malondialdehyde (MDA) was significantly declined in the experimental groups compared with the control group. In conclusion, Cu supplemented at level of 125 mg/ kg diet either copper nitrate or copper sulfate improved the productive performance, profile of lipid metabolism and oxidative response enzymes of broiler chickens. Broilers fed organic form of copper (copper nitrite) had better growth and immune response than those fed inorganic form of copper (copper sulfate) sulfate.
Dielectric function, screening, and plasmons in two-dimensional graphene

The dynamical dielectric function of two-dimensional graphene at arbitrary wave vector $q$ and frequency $\ensuremath{\omega}$, $ϵ(q,\ensuremath{\omega})$, is calculated in the self-consistent-field approximation. The results are used to find the dispersion of the plasmon mode and the electrostatic screening of the Coulomb interaction in two-dimensional (2D) graphene layer within the random-phase approximation. At long wavelengths $(q\ensuremath{\rightarrow}0)$, the plasmon dispersion shows the local classical behavior ${\ensuremath{\omega}}_{\mathit{cl}}={\ensuremath{\omega}}_{0}\sqrt{q}$, but the density dependence of the plasma frequency $({\ensuremath{\omega}}_{0}\ensuremath{\propto}{n}^{1∕4})$ is different from the usual 2D electron system $({\ensuremath{\omega}}_{0}\ensuremath{\propto}{n}^{1∕2})$. The wave-vector-dependent plasmon dispersion and the static screening function show very different behavior than the usual 2D case. We show that the intrinsic interband contributions to static graphene screening can be effectively absorbed in a background dielectric constant.
Improvement of Salinity Tolerance in Rice Seedlings by Exogenous Magnesium Sulfate Application

This study was conducted to develop the salt tolerance of rice by exogenous application of magnesium sulfate supplement (MgSO4). The salinization was carried out on 7-day-old rice seedlings including BC15 (salinity tolerant) and DT84DB (salinity susceptible) varieties with 0.5 mM MgSO4. The exogenous application of MgSO4 significantly improves the growth of seedlings of both varieties. In addition, antioxidant activities increase in line with the raise of total phenolic and total flavonoid contents. Remarkably, the contents of momilactone B (MB) and phenolic compounds including tricin, ρ-coumaric, salicylic, cinnamic, benzoic, and ferulic acids simultaneously rise in both varieties treated by salinity and 0.5 mM MgSO4. Interestingly, MB was not found in the salt-treated samples but presents with considerable contents in the salt and MgSO4-treated cultivars. The findings imply that MgSO4 may significantly improve the salt tolerance of rice seedlings through the enhancement of secondary metabolic synthesis pathways, of which phenolic acids and momilactone B may play a crucial role in the response of rice to salt stress. In contrast, momilactone A (MA) did not show any contribution in salinity tolerance of examined rice cultivars at the early seedling stage. Further investigations on the effect of MgSO4 exogenous application in improving salinity tolerance of various rice varieties at other growing stages should be carried out.
