The study examined the use of exudates/resins from extracts of natural origin for environmentally friendly materials derived from tree trunks. Gummy exudates/resin was applied directly to the steel reinforcement by the coating of different thicknesses. The purpose of this study is to determine the role of exudates/resin against adverse attack on reinforcement embedded in concrete, exposed to the severe environment due to its waterproofing and resistance to surface modification of steel reinforcement and coating application. In the flexural strength test, the maximum value was 28.36% compared to the corroded and coated sample values of -20.02% and 28.37%, respectively. Mean differential and percentile range controlled (0.96kN and 3.07%), corroded (0.82kN and 2.08%), coated (1.13kN and 3.33%). The results of midspan deflection mean value and percentage difference were controlled (0.27kN and 1.66%), corroded (0.57kN and 4.61%), and coated (0.27kN and 1.68%). The results showed a lower elongation load in the controlled and coated samples with reduction values over the corroded samples with higher elongation loads and higher values compared to the reference range (controlled). The cross-sectional area of reinforcing steel recorded the mean differential values and calculated percentile values, corroded (0.06 mm and 5.21%) and coated values (0.05 mm and 7.12%). The results obtained showed the effect of corrosion on the mechanical properties of reinforcing steel with a decrease in the diameter of the reinforcement in the corroded sample, while the coated sample showed an increase due to the thickness of the exudates paste layer. The differential computed average and percentile value of the yield strength and ultimate tensile strength are controlled (5.31MPa and 1.16%) and (2.53MPa and 0.02%), the corroded values are (3.18MPa and 1.05%) and (2.53MPa and 0.02%), the coated values are (5.3MPa and 1.16%) and (2.53MPa and 0.02%). The percentages of maximum weight loss/gain for corroded and coated samples were -28.54% and 43.9%, respectively. The calculated data showed a decrease in the value of the corroded sample as a result of the corrosion attack, which led to a decrease in the registered weight, whereas the coated sample showed an increase in weight compared to the reference value of the controlled sample due to the different coating thickness.

The characterization of char from waste tyre pyrolysis is evaluated in this work. Disused tyres retrieved from vehicle users and dump hills in Akure and its environment in South West Nigeria were pyrolysed in a refurbished 17.4 litre capacity fixed-bed batch thermochemical reactor. The waste tyres were cut into sample sizes of 20 mm × 30 mm manually and then weighed into various portions of 1kg each. 1kg mass of the washed waste tyres was pyrolysed in each batch of pyrolysis experiment to obtain char at different pyrolysis temperatures of 250oC, 350oC, 450oC, and 600oC respectively. Proximate and ultimate analyses of the char resulting from the pyrolysis were carried out. The pyrolysis process produced char with an average of 83.30% carbon composition 5.45% hydrogen, 0.52% nitrogen, 1.17% sulphur and 1.90% oxygen composition. The analysis of percentage composition of the raw scrap tyre samples gave 79.86% for carbon, 7.35% hydrogen, 0.39% nitrogen, 1.57% for sulphur and 6.50% for oxygen. The ultimate analysis of the char resulting from pyrolysis gave an average value of 38.83 kJ/kg for the heating value and 470.00 kg/m3 for specific gravity. The average fixed carbon content was 33.38% while the volatile matters gave an average of 58.40%. The ultimate analysis of the raw tyre samples gave values of 36.10 kJ/kg for the heating value and 343.00 kg/m3 for specific gravity.

Mucormycosis is an uncommon disease caused by fungus of the order Mucorales. The disease has an aggressive course with high morbidity and mortality. It usually affects immunocompromised patients with some systemic debility or some inciting factor like trauma or some invasive procedure. Rhinoorbitocerebral type is a common variety with a typical order of system involvement. The disease has diagnostic challenges due to non-specific presenting picture, non-specific radiological changes and non- specific diagnostic tests. Biopsy and histopathological examination form the definitive diagnosis. Early institution of systemic antifungal therapy with surgical debridement are the cornerstones in management. Particular rise in number of mucormycosis cases has been noted during COVID-19 pandemic. We present a case report of an immunocompetent child who presented during the early phase after first wave of COVID-19 pandemic, with an atypical presentation, with a progressive course, delayed diagnosis but an appropriate management and satisfactory outcome.

Background: This study aimed to determine patients’ perception of pain during scaling and determine its relationship with their level of dental anxiety. It also evaluated differences in the pain perception between genders and its relationship with age. Materials and Methods: The cross-sectional study was conducted at the Periodontology Unit of the Lagos State University Teaching Hospital. Supra-gingival scaling was performed on the six mandibular anterior teeth of 94 consenting participants. The Visual Analog Scale (VAS) was used to record the patient's pain level while the Modified Dental Anxiety Scale (MDAS) was used to measure dental anxiety. Gender and age differences between Anxiety Scores and VAS was compared using Student’s unpaired t-test and ANOVA respectively. P-value < 0.05 was considered to be statistically significant. Results: Females had higher overall Mean MDAS scores (12.87±4.79). Similarly, respondents aged 18-40years had higher Mean MDAS scores (12.00±4.65) than those aged 41-85years even though the association was not significant. Females also had higher OHI-S scores (2.57±1.22), Bleeding Index scores (48.57±39.38), Gingival Index (1.57±0.58) scores than males though the association was not significant. In addition, females had higher mean VAS scores (31.44±23.44) than males and those aged 18-40 years had higher mean VAS scores (31.44±23.44) than those aged 41-85 years though the association was not significant. Conclusion: Scaling and polishing was associated with higher pain and anxiety levels among females and younger respondents while patients with worse oral hygiene and gingival inflammation experienced more discomfort during the procedure. The proportion of patients that experienced severe pain increased with increased dental anxiety but the association was not significant. It is recommended that patients attending for scaling and polishing are screened with appropriate tools like MDAS while awaiting the procedure.

This research work investigated the application of Chrysophyllum albidum exudates/resin extracts as potential inhibitors in the control and prevention of corrosion attacks to reinforcing steel embedded in concrete slabs and are completely immersed in 5% sodium chloride (NaCl) solution in water and accelerated for a rapid corrosion process for 360 days with interval checks and routine tests of 90 days, 180 days, 270 days, and 360 days for examination and record documentations for comparison of tested sample performances. The maximum yields of controlled and coated samples were -112.42 mV and -118.97 mV, which showed the relationship between corrosion potential and opportunity in the reference range as 𝐸corr > −200mV and the uncoated samples, the calculated maximum value is -338.49 mV, the result is within the reference value of the dependence between corrosion potential and probability of −350mV ≤ 𝐸corr ≤ −200mV indicating a high-value range of 10% or an uncertain corrosion probability. The comparative results from the referencing range (controlled), showed that corroded samples exhibited corrosion presence resulting from the induced corrosion acceleration against coated samples that exhibited absence of corrosion. The results of the controlled concrete and armored resistance samples obtained at the maximum average value of 15.06kΩcm and 16.12kΩcm with a data value of 10 < 𝜌 < 20 (low) compared to a corrosion value of 9.82 k cm with a specification of 5 < 𝜌 < 10 (high). The calculated maximum percentage value of the controlled yield point is 7.05% relative to corrosion and coverage value -6.54% and 7.12% and the possible differential values of 0.02% controlled, 0.02% corroded, and 0 .15% covered. The percentage of maximum tensile strength calculated in the control is 2.39% relative to the corrosion and coating value -3.35% and 3.51% and the potential differential value is 0.04% controlled, 0.01% corroded and 0.04% coated. The yield strength, tensile strength, and deformation ratio of the mean, percentile, and controlled differential potential values, uncoated (corroded) and layered concrete slab samples were determined. , coated samples had higher breaking loads compared to corroded samples with reduced breakdown load and low load-bearing capacity and with mean and percentile values in relation to the reference range, whereas uncoated (corroded) samples, had a load-bearing capacity which is low and a reduced value compared to the reference range.For comparison, the results of corroded samples showed a decrease in value compared to the diameter of the reinforcement before and after the induction accelerated corrosion test with a percentage decrease in value from 0.428% to -1.48% and an average value in the range from 11.93 mm to 11. 88 mm.The differentials in mean values and relative percentiles between coated and corroded samples ranged from 69.57% to -41.03%. The decrease in mean and percentage values indicates that the corrosion effect causes a decrease in diameter and cross-sectional area, fiber degradation, rib reduction, and surface modification, while the exudate/resin-coated elements are validated in the work due to differential s in coating thickness. For comparison, the results obtained show a reduction/reduction and reduction of mean and percentile values for coatings with 0.070kg to 0.06kg and corrosion 7.81% to -5.8%. The summary results show that the corrosive effect had an impact on the rebar embedded in the concrete slab samples exposed to induced corrosion

Phosphate solubilizing microbes (PSM) are beneficial soil microbes that they have the ability to dissolve unavailable soil P into available and can mineralize organic P into inorganic P. The experiment was conducted to study the effect of phosphate solubilizing microbes on soil P, yield of upland rice plants and the efficiency of P fertilizer on marginal soil. Design experiment of Randomized Block Design (RBD) was used in field experiment, consisted of two factors and three replications. Phosphate solubilizing microbe as the first factor consisted two levels i.e without and with PSM (a mixture of Pseudomonas sp. and Penicillium sp.). While the second factor was P fertilizer consists four levels ((0, 50, 75 and 100 kg P2O5 ha-1). The result of experiment showed that PSM improved soil phosphatase activity and yield of upland rice on marginal soil. Phosphate solubilizing microbe increased soil organic P mineralization was characterized by a decrease in organic P. Inoculation of PSM with phosphate fertilizer dose of 75 kg P2O5 ha-1 (75% recommended dose) gave best effect to soil phosphatase activity, soil P status and yield of upland rice in marginal soil.

The purpose of this research is to examine the factors that influence the application of the electronic tax filing system (e-filing) of taxes in the order of adaptation of policies by the developing government wherein Indonesia relies on a self-assessment system (SAS) which implements voluntary compliance by taxpayers. Using the theory of planned behavior, the technology acceptance model (TAM) as a theoretical basis, this study looks at the effects of taxpayer compliance (TC), perceived usefulness of function (PU), taxpayer satisfaction (US), and taxpayer behavior (BI) in Indonesia in single study. This study is cross-sectional and correlational. Data were collected through a questionnaire survey of 298 taxpayers. Data were analyzed using Statistical Package for Social Sciences. This study is cross-sectional and correlational. Data collected through a questionnaire survey of 298 taxpayers. Data were analyzed using Statistical Package for Social Sciences. The results show that taxpayer satisfaction, perceived usefulness of taxpayers functions, and behavior contribute to tax compliance by 25.25%, that taxpayer satisfaction and taxpayer behavior are significant predictors of tax compliance and taxpayer behavior strengthens the moderating relationship between taxpayer satisfaction and tax compliance. At the same time, the perception of the usefulness of the function does not have a significant value on tax compliance. Given that this study was cross-sectional, monitoring changes in behavior over time was not possible. The results are helpful for policymakers and taxpayers in Indonesia. To the researchers knowledge, this is the first study to examine the contribution of perceived usefulness of function, taxpayer satisfaction, and taxpayer behavior of taxpayer compliance.

Background and objective: Defined as the collection of blood between the chorionic membrane and the uterine wall, subchorionic hematoma can be associated with adverse pregnancy outcomes and even miscarriage. The present study was carried out in order to evaluate the effects of first-trimester subchorionic hematoma on pregnancy outcomes. Patients and methods: The present study was an observational prospective case-control study which was conducted on 200 pregnant women in Erbil teaching hospital, Erbil, Iraq over a period of one year from April 2019 to April 2020. The women were assigned into two groups, a case group consisting of 100 women with subchorionic hematoma and a control group including 100 women without subchorionic hematoma. Required data were collected based on the women’s full history and examination. The collected data were analyzed using the Statistical Package for the Social Sciences (SPSS version 25.0). Results: age of most of women in our study was between 20-30 years old, although we couldn’t find any association between subchorionic hematoma and age of the woman. Most of the cases (97%) and controls (95%) did not smoke (p-value=0.721). The cases and controls were not significantly different in terms of miscarriage, most of them did not have miscarriage (p-value=0.182). The results revealed a significant association between current miscarriage and history of previous miscarriage (p-value<0.001). The cases and controls were not significantly different in terms of 2nd and 3rd trimester vaginal bleeding, mode of delivery, intrauterine fetal death, newborn admission to NCU, congenital anomalies, age, parity, Apgar score in first minute, and Apgar score in 5th minute (p-value>0.05). However, they were significantly different regarding their birth weight (p-value=0.12). Conclusion: There are no significant correlations between having subchorionic hematoma and miscarriage; however, the odds of miscarriage are slightly higher in women with subchorionic hematoma. Newborns of women with subchorionic hematoma generally have a lower birth weight.
