This study evaluated the naturally extruded exudates/resin from plants of inorganic origin with eco-friendly and environmentally non-hazardous materials derived from tree trunks. Exudates/viscous adhesive is then embedded into the concrete beam after layers of different thickness and applied directly to the steel reinforcement. This study further aimed to determine the role of exudates/resins in harmful attacks on reinforcement by water tightness and durability (resistance) and modifications of steel reinforcement surface due to coating. In comparison, the results of the flexural strength exhibited at the maximum for the controlled sample is 27.86% compared to the corroded with -20.75% and coated sample of 27.87%, respectively. Differential mean values and percentile ranges were checked to be (0.55kN and 1.43%) for the controlled, (0.66kN and 1.04%) corroded and (0.52kN and 1.69%) coated. Corroded specimens fail with a lower load applications and high yielding, whereas coated specimens have a higher load to failure and lower yield occurrence. The results further confirmed that the flexural failure loads of the controlled and coated specimens maintain a narrow range of values over the corroded specimens at moderate, reduced and lower loads. The comparative results showed that the maximum value of the controlled state is -38.58% compared to 63.61% corroded and controlled -37.96%. The recorded mean and percentage difference values were examined and computed to be (0.26kN and 0.93%), corroded (0.26kN and 2.42%) and coated (0.27kN and 0.92%). The results showed a lower failure deflection load in the controlled and coated samples with a reduced value over the corroded sample with a higher failure deflection load and an increasing value compared to the reference range (controlled) and the layered (coated) sample. The comparative obtained results during and after the corrosion test for the maximum value of the rebar diameter is 0.53% compared to the corroded -0.74% and the coated sample 0.85%. The computed mean differential and percentile values were (0.02% and 0.03%), the corroded values were (0.03kN and 0.11%) and the coated values were (0.01kN and 0.11%). The results showed the effect of corrosion on the mechanical properties of reinforcing steel with a smaller diameter, where the average value and the percentage of corroded samples decreased, while the controlled and coated samples showed a preserved condition, with an increase in the diameter of the coating emanating from the varying coating thicknesses from the exuates /resin. The cross-sectional area of the reinforcing steel mean and percentile values calculated from the corroded values are (0.02 and 6.19%) and the coated values (0.02 mm and 5.21%). 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 in the thickness of the exudate paste layer. The differential calculated average and percentage yield strength and ultimate tensile strength (6.93MPa and 5.46%) and (2.53MPa and 0.02%), the corrosion value was (2.81 MPa and 5.01%) and (2.53 MPa and 0.02%). the values covered are (3.98MPa and 5.46%) and (2.56MPa and 0.01%). From the data obtained and compared, the yield strength and tensile strength values of the corroded sample take into account the mean and percentile values reduced with load damage with low application. The comparative strainn ratio obtained from the calculated maximum values for the mean and percentile values for the control was -3.19% compared to the corroded and overlaid values of 3.29% and -2.88%, respectively. The mean differential and percentile values obtained for the control were (0.42 and 0.3%), corroded values (0.42 and 0.32%) and closed values (0.43 and 0.31%). The results showed that the corroded sample had a higher percentage of deformation due to lower breaking load and higher yield strength, while the coating had a higher breaking load with lower yield strength. The calculated data for the maximum percentage of reinforcement weight before corrosion test for controlled, corroded and coated values were 0.05%, 0.05% and 0.07%. The maximum comparison values recorded after the corrosion test for the controlled sample remained the same, with no trace of a corrosive effect, as it was collected in fresh water, for the corroded and coated samples the values obtained were -6.82% and 7.76%, respectively.

The application of Sticky gummy paste of anogeissus combretaceae exudates/resin extracted from tree extrudes was studied. It was used as an inhibitive material to control the manifestation corrosion effect on steel bars in built-in high salinity coastal areas. The extracted exudates/resin was coated to reinforcing steel and embedded in the concrete slab, exposed to corrosive media with high salt concentration. The results of maximum calculated percentile of the controlled sample value is -64.36% compared to the corroded and coated value of 154.98% and -60.05% and the controlled corrosion potential differential value is 1.19%, corroded 4.66% and coated 0.73% . The maximum yield of controlled and coated samples was -108.04mV and -122.85mV, which showed the relationship between corrosion potential and probability reference of 𝐸corr > −200mV as a reference range. For non-coated (corroded) samples, the maximum calculated value is -310.58mV; the result is within the reference value of the relationship between corrosion potential and probability of −350mV ≤ 𝐸corr ≤ −200mV value indicating a high value range close to 10% or an uncertain corrosion probability in comparison to the reference range. The maximum calculated percentile of the controlled sample concrete resistance is 141.67% compared to the corroded and coated value of -52.84% and 131.05% and the maximum percentile differential of control are 23.15% compared to the corroded and coated value of 3.87 % and 18.94%. The results of the controlled and layered concrete resistance samples obtained a maximum average value of 15.96kΩcm and 15.47kΩcm with a data value of 10 < 𝜌 < 20 (low) compared to a corrosion value of 7.28kΩcm with a specification of (5 <𝜌 < 10) and with the reference range of the relationship between concrete resistance and corrosion probability. The maximum percentile value calculated from the controlled yield strength is 9.96% against corroded sample and the coated value is -9.21% and 10.67% and the possible differentials value is 0.43% controlled 0.43% corroded and 0.52% coated. The calculated maximum values of the controlled tensile strength percentiles were 2.348% against corrosion and the coated values were -4.08% and 4. 27% and the potential differential values were 0.01% checked, 0.01%% corroded and 0 0.01% coated. The coated samples for yield strength, tensile strength and deformation ratio of the average, percentile and differential potential values of the control, plate samples. uncoated (corroded) and coated concrete had higher breaking loads compared to corroded specimens with reduced failure loads and low load bearing capacity and with average and percentile values compared to the reference range, whereas uncoated samples (corroded) indicated a low load-bearing capacity and reduced value compared to the reference range. The diameter of reinforcement after corrosion maximum calculated percentile value controlled 0.043% versus -1.11% corroded and 1.114% coated, the difference in percentage between corroded 0.121% versus 0.008% coated. The effect of corrosion attack on reinforcing steel embedded in the concrete slab and exposed to corrosion induced acceleration effect. The aggregate results show that the corrosion effect causes a weight reduction/weight reduction in the corroded samples compared to coatings with a percentage exposure and an average increase, resulting in a small increase in the volume of the coating thickness. This study shows the effectiveness and efficiency of exudates/resin as an inhibitor against the effects of corrosion on reinforcement embedded in samples of concrete slabs exposed to induced corrosion.

surrounding concrete structure. The research work investigated the application of exudates/resin as an inhibitory substance in averting the effect of corrosion on reinforced concrete structures in the built environment of high salinity. The experimental data tests were carried out on 36 concrete cubes with the first set of 12 controlled concrete samples placed in freshwater for 360 days and the second set of 24 cubes divided into 2 with 12 uncoated samples and 12 coated samples with exudate/resin as described in the test procedure and immersed in 5% aqueous sodium chloride (NaCl) solution for 360 days, routine three months with 90-day intervals, 180 days, 270 days, and 360 days. Comparatively, the minimum and maximum values for average and percentile for failure bond loads, bond strength and maximum slip, cross-sectional reduction/increase, the diameter of rebar before /after corrosion, weight loss/gain. The listed results show reduced values with the application of lower failure loads of corroded samples compared to controlled and coated samples with closer values and higher failure loads. The calculated and comparable value for the bond strength of the controlled samples was 69.572% compared to the corroded and coated samples with -42.481% and 98.031%. The indicative count results showed a reduced value and lower failure load of corrosive samples and for samples coated with a value that increases with the reference value in the controlled sample range. In comparison, the corroded samples showed a lower slip value compared to the controlled and coated samples with a higher slip value compared to the failure status, indicating a contribution to the exudate/resin effect in the slip test. The calculation results show an indication of the effect of corrosion on failure bond load, bond strength, and maximum slip. The presence of corrosion reduces the efficiency of the material used, reduces mechanical properties, and affects the bonding and interactions between the concrete and the steel reinforcement and the surrounding concrete. The results obtained indicate that the effect of corrosion on reinforcing steel hurts the mechanical properties of the cross-sectional area, a decrease in diameter and weight loss and surface modification, thereby reducing the value of control slip and coated samples and reducing the interaction between concrete and reinforcing steel.

The study evaluate the scourge of corrosion effects on reinforcing steel with the application Calotropis procera exudates / resin coated directly in different thicknesses to reinforcing steel, embedded into concrete slabs and exposed to coastal waters with a high concentration of salt to curb the rate and degree of corrosion. The hardened concrete slab is fully immersed in 5% sodium chloride (NaCl) solution for 360 days, with interval inspection and routine tests at 90 days, 180 days, 270 days and 360 days. The maximum calculated percentile control value is -59.22% compared to the corroded and coated values of 229.5% and -59.22% and the controlled potential difference value is 8.8%, 84.28% corroded and 10.43% coated. The maximum yields of the controlled and coated samples were -105.37mV and -122.66mV 6mV, which showed the relationship between corrosion potential and opportunity in the reference range 𝐸corr > −200mV. Corrosion potential probability values of uncoated samples has maximum calculated range of -308.77mV, the result is within the reference value of dependence between corrosion potential and probability of value −350mV ≤ 𝐸corr ≤ −200mV indicates a high range of values, which is 10% or uncertain probability of corrosion. Results in comparison from the reference range (controlled), it is observed that show that non-coated samples showed corrosion potentials with higher values as a result of accelerated corrosion induced as compared to coated samples. The maximum value calculated from the concrete resistance of the controlled sample is 111.34% compared to the corroded and coated value of -54.53% and 135.59% and the maximum value of the percentile difference from the control is 19.17% compared to the corroded and coated value of 3 0.02% and 15.66%. The results of testing controlled samples coated with concrete resistance obtained the maximum average values of 15.28 kΩcm and 17.53kΩcm with a description of the value 10 < 𝜌 < 20 (low) compared to the corrosion value of 7.9kΩcm with specifications 5 < 𝜌 < 10 (high) and with a reference range of dependence between concrete resistance and corrosion probability at significant corrosion probability. The calculated maximum percentage of the controlled yield strength was 8.31% compared to the corroded and coated values -7.35% and 8.66% and the possible difference values of 0.45% controlled, 0.62% corroded and 0.72% coated. The calculated maximum percentage of the controlled of ultimate tensile strength is 1.99% relative to corroded value of -2.69% and the coated values of 2.78%% and with differential potential values of 0.01% controlled, 0.01% corroded and 0.01% coated. Comparatively, corroded samples exhibited high yielding to low load application representing the effect of corrosion on the mechanical properties of reinforcing steel that has resulted to low load carrying capacity, the corroded also recorded higher strain ratio as compared to the coated to the parameters above. The maximum calculated percentage was set at 0.929% versus corroded - 0.919% and coated at 1.043%, with a percentage difference in corrosion of 0.004% versus 0.067% coated. For comparison, the results of the corroded samples showed a reduction values compared to the diameter of the reinforcement before and after the induction accelerated corrosion test with a percentage decrease in value from 0.048% to -0.919% and an average value in the range from 11.96mm to 11.91mm. Comparatively, the results obtained show a reduction of the mean and percentile values for corroded from 0.07 kg to 0.05 kg and 35.19% to -23.61%. The summary results show that the corrosion effect on corroded samples causes a decrease in weight compared to coatings with percentile values and an increase in mean values, which causes a slight increase in volume with coating thickness.

The research evaluated Musanga cecropioides extrusion viscosity gummy paste (exudate/resin) obtained from trees as a corrosion inhibitor material to slow down the impact of corrosion on steel bars embedded in concrete and constructed in high-salinity coastal areas. The exudates/resin extracted is coated on the steel bar and embedded in the concrete slab, exposed to the corrosive medium with high salt concentration. The hardened concrete slab is completely immersed in a 5% aqueous sodium chloride (NaCl) solution, and the rapid corrosion process accelerated for 360 days with interval inspections and routine tests at 90 days, 180 days, 270 days, and 360 days for comparative evaluations for both uncoated and coated samples. The computed maximum control percentile value is -67.28% compared to the corroded and coated values 241.14% and -64.4% and the controlled potential difference value is 4.99%, corroded 60.25%, and coated 6.29%. The maximum yields of the controlled and coated samples were -105.1mV and -113.74mV, with the result obtained, this showed an indicative relationship between corrosion potential and probability as 𝐸corr > −200mV as the reference range. These results of potential Ecorr results showed indication that the values of controlled and exudates/ resin coated specimens are low with the range of 90% probability that no reinforcing steel corrosion is occurring in that area at the time of measurement (10% risk of corrosion which indicates a 10% or uncertain probability of corrosion. For the non-coated sample, the maximum obtained computed value is -328.64mV, the results are within the range reference of dependence between potential and corrosion probability of the value −350mV ≤ 𝐸corr ≤ −200mV indicating a high range of values, notifying a 10% or uncertain probability corrosion. 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 exudates/resins exhibited inhibitory characteristics against corrosion attacks on reinforcing steel embedded in the concrete slab, exposed to corrosive media by the formation of the resistive coating. The maximum computed percentile of the controlled sample of concrete resistivity is 149.21% compared to the corroded and coated value of -59.26% and 153.52% and the maximum percentile difference of control is 5.38% compared to the corroded and coated value of 1.3 % and 8.09%. The results of the controlled and coated concrete resistivity samples obtained at an average maximum value of 15.85kΩcm and 16.23kΩcm with a data value of 10 <𝜌 <20 (low) compared to a corrosion value of 6.45kΩcm with specifications (𝜌 < 5, 5 < 𝜌 < 10, 10 < 𝜌 < 20, 𝜌 > 20) and with the reference range of the relationship between concrete resistivity and corrosion probability, the significant corrosion probability (𝜌 < 5, 5 < 𝜌 < 10, 10 < 𝜌 < 20, 𝜌 > 20) was very high, high, low to medium and low, for corrosion probability. The computed maximum percentile of the controlled yield strength is 8.96% compared to the corroded and coated values -7.83% and 9.08% and the possible difference values are 0.45% controlled, 0.49% corroded, and 0.59% coated. The maximum computed difference in values is 1.83MPa and 0.01% the controlled tensile strength is 3.478% against the corroded and coated values, respectively are -2.942% and 5.408% and the potential difference values 0.01% controlled, 0.01%% corroded and 0.01% coated. The yield strength, tensile strength, and strain ratio of the mean, percentile, and differential potential values of the control, uncoated (corroded) and coated concrete slab samples showed that coated samples had higher failure loads compared to corroded samples with reduced and decreased failure loads and low load-bearing capacity and with average values and percentiles to the reference range, while uncoated (corroded) samples recorded lower loads carrying capacity and reduced value compared to the reference range. The diameter of reinforcement after corrosion maximum computed percentile value is 0.039% as against -1.116% corroded and 1.128% coated; the difference in percentile is 0.005% corroded versus 0.008% coated. The results of the comparative of corroded samples show the reduction in values compared to the diameter of the reinforcement before and after the induction accelerated corrosion test with a percentile range for the reduction value from 0.039% to -1.116% and the average value in the range from 11.99mm to 11.94mm. The decrease/increase (diameter) in the cross-section of the minimum and maximum mean and percentile values were controlled 100%, with no decrease or increase in the description after 360 days of immersion in fresh water. The decrease in mean and percentile values indicates that the corrosion effect causes a reduction in diameter and cross-sectional area, fiber degradation, ..........

Using Halliday’s systemic functional linguistics and the practice of Critical Discourse Analysis, the study demonstrates how ideas and thoughts are represented in selected speeches the governor of Rivers State. This personality is analysed to have certain ideologies as made manifest in his use of language. Recognising that situation actually determines what to say, recognition is equally given to the language features of the speeches in relation to the functions in particular contexts. The study revealed that Wike’s speeches open with words of appreciation God and humanity. In second step, intentions are declared by the governor who assures the people of Rivers State that their suffering has already gone into history. The governor is seen to have neglected the needs for international relations and foreign policies. He unveils his plans for his administration like restoring the legislature’s autonomy, restoring and enhancing independence of the judiciary, appointing and re-opening of the state’s chief judge and courts, amendment of chieftaincy laws among others. The grammar of the speech is featured frequently with we-pronoun, which is not merely a discourse feature but a sign of collectivity and togetherness. The governor also appeals for unity and cooperation from all the citizens of the state. He feels that the state is in deep trouble which requires careful plan to tackle it. In a similar fashion, he promises to equally cooperate by returning power to the people in the conduct of common affairs.

Background: Chronic Myeloid Leukaemia (CML) is a myeloproliferative neoplasm (MPN) of abnormal marrow stem cell with BCR-ABL1 fusion gene as a pathognomonic feature. In resource-poor countries, clinical and laboratory parameters were invaluable tools used in the diagnosis. However, the advent of GeneXpert technology was a paradigm shift in the detection of the fusion gene. Aim of the study: To highlight the clinical usefulness of geneXpert in the evaluation of clinical and laboratory features of newly diagnosed patients. Patients and Methods: A cross-sectional descriptive study was conducted at University of Nigeria Teaching Hospital (UNTH) Enugu. Sixty-five BCR-ABL 1 positive consenting patients were evaluated using demographic, clinical and laboratory data. Data was analyzed using GraphPad Prism software version 9 with probability <0.05 as statistically significant. Results: A total of 65 patients with mean age 45.22 + 15.44 years were studied. Age group 39 – 49 were mostly affected 20 (30.8%) with Enugu State having the highest disease burden 20 (30.8%). Abdominal swelling was the most common presenting feature 57 (87.7%) while splenomegaly was the most common finding on imaging 60 (92.3%). Mean WBC and BCR-ABL1 were 207.37 + 87.57 x 109/L and 41.02 + 24.53% (IS) respectively (r = -180, P = 0.015). Majority of the cases were in chronic phase 56 (86.2%). Risk assessment of cases on presentation using Sokal and Hasford scores were statistically significant (t = 20.23, P < 0.0001), [CI = 1429 to 1739]. Conclusion: There was improved diagnostic yield of cases of CML using the molecular diagnostic technique.

Meditation known as influential factor on many neurocognitive variables, memory is one of them. Studies have identified that meditation affects working memory. This study aimed to identify the effect of mindfulness meditation on verbal memory and composite memory. Twenty (n=20) male volunteered students age ranged between 21 to 29 years were taken from colleges and university of Kalyani, West Bengal, India. As the subjects were randomly divided into two groups and named as control Group and Experimental group. At first, Linearity, Homoscadasticity, and Normality of data were checked by Kolmogorov-Smirnov test, Breusch-Pagan-Godfrey and Kolmogorov-Smirnov test respectively in SPSS 23 software. In present study the mean, standard deviation (SD), paired sample‘t’ test were used for observing the effect of meditation programme. Independent sample t test was also used to identify the base line difference between the groups. After fourteen weeks of mindful meditation practice significant improvements were seen in verbal memory and composite memory of the experimental group. The findings suggest that mindfulness meditation practice can improve verbal memory composite memory of an individual.
