This study investigated the effect of corrosion on the flexural behavior and midspan deflection of reinforced concrete beam members. Control, corroded, and resin-coated concrete beam specimens were tested to determine their failure load, midspan deflection, rebar diameter measurements, and mechanical properties. The results showed that corrosion significantly reduced the flexural strength and increased the midspan deflection of beams due to weakening of the reinforcing steel. The average failure load of corroded beams decreased by 25.73% compared to the control beams. Similarly, the average midspan deflection of corroded beams increased by 103.8% over the control beams. Measurements of rebar diameters before and after corrosion revealed reductions of up to 0.87% in corroded samples, substantiating corrosion-induced thinning. Additionally, mechanical properties testing showed decreases in ultimate tensile strength, yield strength, and strain ratio while increasing ductility for corroded rebars. Resin coating prevented much of the strength loss and provided protective benefits near that of the control specimens. The relationship between failure load, midspan deflection, diameter measurements, mechanical properties and corrosion damage was investigated through analytical comparisons. Corroded samples consistently demonstrated lower failure loads, higher deflections, reduced diameters and strengths versus controls. Conversely, coated samples performed similarly to controls, validating the coating's effectiveness. This research quantitatively confirms literature reports that corrosion degrades reinforced concrete through weakening of rebar-concrete bond and steel deterioration over time if left unprotected. The findings emphasize the importance of mitigating corrosion to ensure structural integrity, safety and durability of reinforced concrete infrastructure.

This study investigated the performance of Celtis zenkeri exudates in preventing galvanised steel exposed to acid concentrated water and soil. The study was performed in order to find an alternative coating substance that can reduce the corrosion of galvanised steel pipes exposed to corrosive water and soil media. Various steel specimens were cut into portions and coated with the exudates at 25 - 50µm thickness. To accelerate the rate of corrosion, 0.5M hydrochloric acid (HCl) was added to tap water in a container. Also, the same concentration of HCl was equally added to soil samples. Uncoated steel specimens were immersed in the acid concentrated water and soil, servicing as control sample. The rate of corrosion was monitored for 30 days (720 hours). The inhibition efficiency of the exudates for both corrosive media was compared. Results showed that the weight loss and corrosion rate of galvanised steel decreased with increase in coating thickness. Comparatively, the weight loss and corrosion rate in the uncoated specimens were higher than the coated specimens. With 25 - 50µm coating thickness, the decrease in corrosion rate ranged from 0.01272 to 0.0027mm/yr for specimens immersed in water and from 0.2226 to 0.0185mm/yr for specimens buried in soil, while for uncoated specimens, the corrosion rate was 0.2793mm/yr and 0.4150mm/yr for specimen immersed in water and soil respectively. The inhibition efficiency of Celtis zenkeri exudates increased with coating thickness, which ranged from 54.46 – 99.03% for specimens immersed in water and 46.36 – 95.54% for specimens buried in soil at 25µm – 50µm coating thickness. The results demonstrated that Celtis zenkeri exudates can be used as corrosion inhibitor for steel exposed to corrosive media.

Background: Polypharmacy, the concurrent use of multiple medications by an individual, presents challenges in medication management, patient safety, and healthcare outcomes, particularly among older adults. In Saudi Arabia, the prevalence of polypharmacy is increasing due to the aging population and the burden of chronic diseases. Understanding healthcare providers' awareness and practices regarding medication switching is crucial for optimizing medication use and improving patient outcomes. Study Aim: This systematic review aims to synthesize and analyze existing literature on healthcare providers' awareness of medication switching for polypharmacy patients in Saudi Arabia. The study focuses on pharmacists and physicians, exploring their knowledge, attitudes, and practices related to medication management, deprescribing, pharmacovigilance, and Medication Therapy Management (MTM) services. Methodology: A systematic search was conducted across major databases, including PubMed, Scopus, and Google Scholar, using predefined search terms related to polypharmacy, medication switching, healthcare providers' awareness, and Saudi Arabia. Eligible studies were selected based on inclusion criteria, including study design, setting, participants, and relevance to the study aim. Data extraction and synthesis were performed to analyze key findings and themes related to healthcare providers' awareness of medication switching. Results: Six eligible studies were included in the systematic review, encompassing survey-based investigations, cross-sectional studies, and qualitative studies conducted in various healthcare settings across Saudi Arabia. The findings revealed gaps in pharmacists' and physicians' knowledge regarding Potentially Inappropriate Medications (PIMs), Drug-Drug Interactions (DDIs), pharmacovigilance practices, and deprescribing strategies. Recommendations for improving pharmacists' education, enhancing pharmacovigilance practices, and promoting collaborative care models were highlighted. Conclusion: Healthcare providers in Saudi Arabia demonstrate varying levels of awareness and practices regarding medication switching for polypharmacy patients. There is a need for targeted educational interventions, standardized pharmacovigilance practices, and collaborative efforts among healthcare providers to optimize medication use, reduce polypharmacy-related risks, and improve patient outcomes.

Corrosion of steel reinforcement is a major factor affecting the durability and strength of reinforced concrete structures. This study investigated the influence of plant-derived corrosion inhibitors, applied as coatings, on the bond strength between reinforcing steel and concrete. Thirty-six 150 mm concrete cubes with 12 mm diameter embedded steel bars were prepared and divided into uncoated, corrosion inhibitor coated, and control groups. The samples were immersed in 5% sodium chloride solution over 360 days to accelerate corrosion. Pull-out testing measured the bond strength and failure load. The corroded samples showed 31-26% lower bond strength and 82-87% higher maximum slip than controls, indicating corrosion damage at the steel-concrete interface. However, inhibitor-coated samples displayed 24-36% higher bond strength and 42-43% lower maximum slip versus corroded samples. Although the coatings did not fully restore original bond strength, this demonstrates their effectiveness at protecting bond properties. Microscopic analysis revealed non-uniform, localized corrosion preferentially initiated at steel defects. Statistical correlations confirmed the direct relationship between steel weight loss and reductions in post-corrosion rebar weight due to material loss. While nominal rebar diameters showed minimal differences between sample types, localized diameter reductions and cross-sectional area increases in corroded samples highlighted discrete corrosion effects. These were mitigated in coated samples. Together with direct weight loss measurements, this proves corrosion occurred in unprotected samples. Overall, the significant recovery of bond strength, slip resistance, diameter, area, and weight in coated samples validates the success of the natural corrosion inhibitors in reducing steel deterioration and interface degradation. The results provide new insights on optimizing inhibitor coatings to maximize corrosion protection for reinforced concrete structures.

Black humor emerged as a distinctive fictional genre in the United States in the 1960s. In the creative process, novelists tend to emphasize the unique charm of this genre through the portrayal of anti-heroes. Thomas Pynchon is a forerunner in American black humor novels during the 1960s and 1970s, and his masterpiece Gravity’s Rainbow is an outstanding example of this genre. This article focuses on two representative anti-heroes in Gravity’s Rainbow, Tyrone Slothrop and Roger Mexico. Through a thorough analysis of Pynchon’s humorous descriptions of the difficulties faced by these two characters, the black humor characteristics of this novel are interpreted, and readers can gain a deeper understanding of Pynchon’s creative style and the essence and appeal of black humor.

We assessed the ameliorative effect of Virgin Coconut Oil (VCO) following atrazine-induced inflammation in rats. Adult male Wistar rats weighing 180 - 200 g body weight were separated into two major experimental groups. 35 rats in the test group were divided into five groups of 7 rats: Group 1,2 and 3 received 10 ml/kg body weight of distilled water, 10 ml/kg VCO and 123 mg/kg Atrazine (ATZ) respectively, group 4 was diabetic control and group 5 was diabetic group treated with 10 ml/kg of VCO for 2 weeks, after which the animals were sacrificed, and blood collected for analysis. 35 rats for the recovery group were also divided into 5 groups of 7 rats; group 1 and 2 received 10 ml/kg body weight of distilled water and 10 ml/kg of VCO; group 3,4 and 5 received 123 mg/kg of ATZ for 2 weeks. After the first 2 weeks, group 1,2,3 continued the initial treatment while the rats in group 4 and 5 were administered 10 ml/kg of VCO and 10 ml/kg of distilled water respectively. After 2 weeks all the animals were sacrificed and blood collected for analysis. C-reactive protein (CRP) and interleukin 6 (IL-6) were significantly (p<0.05) raised in VCO control, atrazine and diabetic untreated group when compared to normal control. Following recovery, CRP and IL-6 were significantly lowered in the VCO treated group when compared to ATZ group. ATZ toxicity resulted in increase in inflammatory markers but the withdrawal of ATZ significantly reversed some of these derangements; with more pronounced effect following VCO administration.

Introduction: Immunotherapy is a form of oncologic treatment directed towards enhancing the host immune system against cancer. Immunotherapeutic agents were significantly associated with a higher risk of developing adverse effects in cancer patients. Bevacizumab was significantly associated with higher risk of developing venous thromboembolism, GI perforation such as bleeding and leukopenia in cancer patients. Trastuzumab has led to a significant improvement in the treatment of both advanced and early breast cancer by over expressing HER-2 receptors. It was associated with an important adverse effect, cardiotoxicity. Cetuximab and Panitumumab are monoclonal antibodies targeting the endothelial growth factor receptors (EGFR) currently used for systemic treatment of metastatic colorectal cancer in combination or alone have been reported to be able to induce skin toxicities. Nausea, diarrhea and rash were the most common adverse effects in Pertuzumab alone and Pertuzumab – based therapies. Pertuzumab also increases the risk of clinical heart failure, but not asymptomatic/minimally symptomatic left ventricular systolic dysfunction, in HER2-positive cancer patients. Materials and Methods: An ambispective observational single center study was conducted by collecting details of patients prescribed with Trastuzumab, Bevacizumab Pertuzumab, cetuximab and panitumumab. Retrospective study period of 5 years (2017 November to 2022 November) and Prospective study period of 6 months were conducted (December 2022 to May 2023). Patients of all age groups prescribed with immunotherapeutic agents other than immune checkpoint inhibitors was included and patients who were discharged against medical advice and incomplete data was excluded. Results: Majority of patients in our study were in age groups of 56-65 years with 38.5%. Among 65 patients, 4 of them reported with trastuzumab induced cardiotoxicity and 3 of the patients taking trastuzumab along with pertuzumab also reported with cardiotoxicity. Among 30 patients who were taking bevacizumab, one patient was reported with pneumonitis. We conducted a correlation analysis using chi-square test between study considered drugs and the reported adverse reactions. All of the patients prescribed with Trastuzumab + Pertuzumab were having ADR. Also, majority of the patients prescribed with Bevacizumab were not having ADR. Since the p-value of chi-square test was found to be <0.001 so there exist a significant relation between drugs prescribed and ADR. Conclusion: We assessed the safety profile of immunotherapeutic agents other than immune check point inhibitors in cancer patients. We also correlated the study considered drugs and adverse drug reaction occurrence, there existed a significant correlation.

Extremely wide bony ridges require surgical procedures in order to insert dental implants. When less than 3 mm is present, different procedures are available, with ridge splitting being one of the most commonly used. The main limitation of this procedure is the angulation of the inserted implant. The two-stage split with transitional implants was created to overcome this drawback and achieve greater bone volume in the intervention area. This case series shows patients treated with this novel procedure. Material and Method: We retrospectively analysed patients who had undergone two-stage ridge expansion (using transitional implants) with at least 9 years of follow-up from the loading of the definitive implant, both in the maxilla and mandible. Data collection was performed by two independent examiners (different from those performing the prosthetic or surgical phase). All data were entered into a database which was managed by computer for the subsequent statistical analysis. The implant was the unit of analysis for descriptive statistics in terms of location, implant dimensions, and radiographic measurements. The primary variable was implant survival and as secondary variables mesial and distal bone loss and final bone crest width achieved after transitional implant integration, before replacement, were recorded. Results: Thirteen patients were recruited, and 30 transitional implants were inserted for width expansion in two surgical stages. These transitional implants were subsequently replaced by definitive implants at 5 months in the maxilla and at 3 months in the mandible. The mean initial ridge width of all two-stage split sites was 2.65 mm (+/- 0.63), range 1.32 to 3.70 mm. After placement of the transitional implants and bone healing, the final mean width of the specimen was 7.60 mm (+/- 0.26), range 4.31 to 12.20 mm. The mean mesial bone loss after loading of the final implant was 0.80 mm (+/- 0.26) and the mean distal bone loss was 0.85 mm (+/- 0.25). Conclusion: The two-stage split technique to achieve a gain in width of the residual bone crest is minimally invasive, predictable and the implants placed in the final (definitive) stage have a high survival rate, as we have seen in the present study with 9 years of follow-up.

Enhancing aesthetics, occlusion and functions is a primary motivation for individuals with open-bite malocclusion seeking orthodontic treatment. Open-bite malocclusion, characterized by a lack of vertical overlap of the anterior teeth, can be effectively treated using anterior vertical elastics. It’s a common, non-surgical orthodontic approach to correct open-bite issues. In this case report, we present the treatment of a male patient with anterior open-bite malocclusion. Initially, the patient underwent a lingual frenectomy followed by an active and passive phase of swallowing rehabilitation by wearing a nocturnal lingual envelope (NLE). Subsequently, a fixed orthodontic appliance was bonded to achieve well-aligned arches, normalize the overjet and overbite with the use of anterior vertical elastics (AVE) and enhance both aesthetics and functions.

Soil salinity poses a significant constraint on plant growth and productivity of maize. Salinity causes reduction in water content in plant tissues, ultimately reducing the photosynthetic capacity and resulting in decreased productivity. Normally in saline soils, chloride ions (Cl−) are particularly considered toxic to certain crops, but in case of maize, sodium ion (Na+) is the main ion responsible for toxicity due to its competition with K+ for binding sites at the plasma membrane. Mycorrhizoremediation which is an enhanced form of phytoremediation is one of the key players in remediation saline soils. Inoculation of these beneficial arbuscular mycorrhizae fungi can alleviate growth inhibition and the adverse effects of salinity in both halophytes and glycophytes by establishing symbiotic relationships with plants. AM fungi colonize the roots of maize plants, perform a crucial role in nutrient cycles in terrestrial ecosystems and own highly efficient and various mitigation mechanisms. Under saline conditions, AM fungi restrict the absorption and translocation of Na+ to shoot tissues and enhance the uptake of K+ in plants. An experiment aiming to enhance salt tolerance in maize through AMF symbiosis was conducted. In this experiment three AMF were evaluated at two salinity levels 66 mM and 100 mM. analysis of data revealed that AMF Ri collect showed showed highest percentage of root colonization at all salinity levels. While plants inoculated with AMF Ce CdG showed highest shoot and root biomass. Furthermore, plants inoculated with Sc CdG and Ce CdG showed a significant reduction in Na+ accumulation and enhance K+ accumulation in shoot and root tissues as compared to non-mycorrhizal plants.

This study aims to evaluate the effectiveness of applying measures to improve students' positivity during Vovinam lessons at FPT University Ho Chi Minh City (FPT University). Thereby, it serves as a basis for monitoring, adjusting, and changing the content of Vovinam subjects to suit the students being trained in the school. We conducted indirect interviews with research subjects using a questionnaire on a Likert scale (5 levels) to identify difficulties and obstacles while teaching and learning Vovinam. After interviews, 10 possible solutions were selected to put into practice. At the same time, conduct a reality check to understand the change in students' positivity after applying measures to enhance positivity during Vovinam lessons. After the experimental period, it was shown that the positivity (including intellectual positivity; cognitive positivity; learning positivity) of students in the experimental group (experimental group) and the control group (control group) both increased. However, the growth of the experimental group was clearly and statistically significantly higher (with P<0.05) than that of the control group’s.

Introduction: The femoral nerve is one of the vital nerves of the thigh region, which has importance in various fields of clinical areas, as well as in the field of Anatomy and the research areas. Femoral nerve blockade plays an important role in surgical interventions of the anterior thigh. Although the femoral nerve is superficial and easier to identify, a profound knowledge regarding the dimensions of the nerve is inevitable to perform successful surgeries and blockades. Objective: The describing study was an attempt to analyze the different dimensions of the femoral nerve in the thigh region of the Malaysian cadavers with relevant clinical implications, as there is a paucity of these studies involving Malaysian cadavers has been reported. Methods: This study had been conducted with the involvement of 78 adult lower limb specimens (cadaveric and disarticulated) of both genders and different ethnicity. Result: The average length of the femoral nerve from the inguinal ligament (IL) till its division and the width at the IL resembled the previous studies conducted on other geographical locations. The width at the division was similar to that of the IL level. The thickness at the IL was 1.32 ± 0.21 (right) and 1.29 ± 0.17 (left); and at the division was 1.50 ± 0.196 (right) and 1.43 ± 0.16 (left). The circumference of the nerve at the IL was 25.44 ± 1.26 (right) and 25.98 ± 0.89 (left); and that at the division was 25.65 ± 1.32 (right) and 25.66 ± 1.25 (left). Conclusion: The knowledge of the morphometric anatomy of the femoral nerve in the thigh region will not only assist neurologists and future researchers but also facilitate clinicians to prevent misdiagnoses and iatrogenic neurological damage.

With increasing concerns over fossil fuel depletion and environmental pollution, research into alternative energy sources has gained significant momentum. Organic wastes, particularly from animals and food, offer a promising substrate for biogas production, providing dual benefits of energy generation and waste reduction. This study evaluates the suitability of food waste, cow regurgitates, and cow dung for biogas production through biodigestion. The objectives were to design a lab-scale biodigester, compare biomethane yields from each waste, and evaluate their effectiveness as fertilizers. The results indicate that all three samples have properties within the acceptable range for digestion. Food waste exhibited the highest methane yield with a daily biogas production of 0.4979 m³/day, corresponding to an energy content of 27,699.45 KJ/day. Cow regurgitates produced 0.2656 m³/day of biogas, yielding an energy content of 14,739.6 KJ/day. Cow dung yielded 0.3213 m³/day of biogas, translating to an energy content of 17,723.65 KJ/day. Microbial analysis indicated the presence of beneficial bacteria and fungi, such as Staphylococcus spp, Proteus vulgaris, Escherichia coli, Enterobacter aerogens, Aspergillus spp, and Mucor spp, which are advantageous for soil conditioning and nutrient cycling. The study highlights the importance of assessing physicochemical properties, nutrient content, and microbial composition to optimise biogas production and explore the potential of organic waste as a sustainable energy source and soil conditioner.
