This article deals with the behavior of isolated piles subjected to two models used in geotechnics (Hardening Soil and Mohr Coulomb) under cyclic lateral loading and their head deformations compared to monotonic loading in sandy soil. The behavior of the cable-stayed bridge piers was predicted using PLAXIS 2D software, based on the results of in situ and laboratory geotechnical studies carried out by the control office for Building and Public Works (BCBTP). Numerical simulation is an alternative to the high cost of large-scale in situ and laboratory studies for describing the behavior of deep foundations. The results obtained show that piles subjected to lateral head loading cause a horizontal head displacement compared with the Hardening Soil and Mohr Coulomb models. Cyclic loading of a pile results in deformation of the soil mass at the surface. Lateral displacement increases with the first few cycles until it stabilizes, generating an irreversible residual displacement due to progressive soil plasticization. Lateral cyclic loading has a favorable influence on pile behavior under cyclic loading, due to the reversible effect on pile displacement.

This study seeks to examine the influence of family long term strategic commitment on the sustainability of family owned enterprises in the Western Highlands of Cameroon. The study made use of primary data obtained through self-administered structured questionnaires. A total of 313 questionnaires were administered to the founders and managers of the family owned enterprises in the Western Highlands of Cameroon. Data collected was entered into SPSS. The study used the Generalised Linear Model (GLM) technique to test the hypotheses. Particular focus was on organisational culture, the involvement of family members and entrepreneurial risk-taking as determinants of the sustainability of family owned enterprises. The results from the GLM regression showed a negative coefficient in the overall sample which indicated that an increase in family long-term strategic commitment predicted a decrease in sustainability of family-owned enterprises. Specifically, organisational culture has a positive coefficient of 0.0862 significant at 10%; the involvement of family members has a negative coefficient of -0.0642 and significant at 10%; and entrepreneurial risk taking has a negative coefficient of -0.00155. This meant that there was a no effect of family long term strategic commitment on the sustainability of family owned enterprises in the Western Highlands of Cameroon; since only organisational culture positively influenced sustainability in the Western Highlands of Cameroon. This study was limited to the Western Highlands of Cameroon by not considering the other ecological zones (Southern rain forests, Central savannah and Northern arid region) of Cameroon. From the findings, the study recommended that founders and managers should engage in calculative risk taking and specify the degree of involvement of family members that could not jeopardised the continuity of the business. The research questions and methods used in this research are new in the aspect of investigating the influence of family long term strategic commitment on the sustainability of family owned enterprises in the Western Highlands of Cameroon.

This paper aims to determine how Digital Transformation Maturity and Digital Change Management affect Work-Life Integration through Digital Work Adaptation as an intervention variable among Government Civil Servants of Central Java's Capital Municipality, which has implemented a digital work system. Quantitative methodology is used in this study, and 200 State Civil Apparatus (ASN) of the Semarang City Government are involved. The data will be analyzed using a quantitative approach through statistical analysis using variance-based structural modeling with PLS-SEM and SPSS, which aims to conduct path analysis with latent variables and coefficients. The findings reveal that Digital Transformation Maturity and Digital Change Management significantly enhance Digital Work Adaptation. Digital Work Adaptation is proven to mediate the relationship between the two independent variables of Work-Life Integration. Digital Change Management has a more decisive influence than Digital Transformation Maturity in forming Work-Life Integration through Digital Work Adaptation. These findings indicate the importance of digital change management and transformation maturity in supporting ASN work and life balance adaptation in the digital era. The study provides theoretical and practical contributions to developing public sector HR management in digital transformation.

Most nanoparticles have diameters that lie within 1 to 100 nm. A variety of metal oxide nanoparticles can be synthesised chemically as well as biologically. NiO nanoparticles, which are synthesised chemically, tend to be highly toxic in their effects. In contrast, synthesis by the route of biogenesis or biomimetics is much more favourable than chemical synthesis. The pre-existing properties of purple cabbage are remarkably enhanced by NiO nanoparticles. Nickel oxide (NiO) nanoparticles were synthesised from the leaves of Brassica oleracea var. capitata. f. rubra (purple cabbage) by reducing Nickel nitrate hexahydrate solution for the formation of NiO nanoparticles. The analysis done using a Particle size analyser reveals the spherical morphology and the size of the NiO nanoparticles. The size and shape were studied under a Scanning Electron Microscope, which shows that the nanoparticle ranges from 34.5 nm to 89.6 nm. The formation of NiO nanoparticles was confirmed by the peaks obtained in Raman spectroscopy and UV-DRS analyser. The peaks that ensure the formation of NiO nanoparticles in Raman spectroscopy are 568.40 cm-1, 1129.46 cm-1 and 1379.07 cm-1 and UV-DRS are 265.60 nm and 339.69 nm. Preliminary phytochemical analysis of the aqueous extract of purple cabbage leaves shows that there is an abundance of phytochemical content present in purple cabbage. From the preliminary phytochemical analysis of purple cabbage, it was observed that the aqueous purple cabbage leaf extract contains alkaloids, sterols, flavonoids, coumarin, tannins, cardiac glycosides, anthraquinones, saponins, quinones, and carbohydrates.
Background: The risk factor for knee osteoarthritis (knee OA) is multifactorial. Socioeconomic status is a risk factor that is commonly underreported. The study aims to find the relationship between socio-economic factors and knee OA, and the influence of these on gender. Methods: This is a case-control study conducted at Orthopaedic Hospital Wamakko, Sokoto, North-Western Nigeria between January 2022 and December 2022. Adult patients aged >40 years with knee OA were included in the study. The data was collected via participants’ interviews through a self-administered questionnaire. The risk factors for knee OA under consideration were occupation, educational level, and monthly income. Data were analysed using the SPSS version 23. The significant level was set at less than 5%. Results: There were a total of 372 patients in the study, with 124 cases and 248 controls in a ratio of 1:2. The average age was 53.7±10.8 (range 40 to 88 years). There were 165(44.4%) males and 207(55.6%) females. For occupation, 201(53.7%) were unemployed, 60(16%) on business, 61(16.3%) were civil servants and 50(13.4%) worked as farmers. For education, 250(66.8%) had non-formal education, and 122(32.6%) had formal education. Most patients (237/57.8%) were high-income earners and 135 (41.7%) were low-income earners. The knee OA prevalence was 13.17% for males and 20.16% for females. In the case group, the majority were unemployed with 63 (50.8%) patients and the least were farmers with only 16 (12.9%). Non-formal education was the most common educational level among the cases with 89(71.8%), and low-income earners are also more common with 74(59.7%) compared with high-income earners with 61 (40.3%). There was a statistically significance result between socioeconomic status and knee OA (OR=0.334, CI=0.214-0.521, and P<0.0001). The odd ratio (OR) for low-income earners among females is 2.238 (CI=1.878-2.666) and p value<0.0001. The OR for non-formal education in low-income earners is 2.332 (CI=1.466-3.709) and p value<0.0001. Conclusion: Low-income level was the most important predictor of knee OA in the study, and the female gender has the lowest income with higher knee OA risk and ....

Background: Lumbosacral radicular pain, commonly known as sciatica, is a prevalent and challenging condition arising from nerve root compression in the lumbar spine due to various underlying pathologies. Epidural steroid injections (ESIs) are often employed for symptomatic relief when conservative treatments fail. While ESIs are minimally invasive and provide localized pain relief, their safety, especially concerning neurological complications, remains a critical concern. Objective: This article reviews the neurological complications associated with ESIs and compares the safety and effectiveness of various corticosteroid formulations administered via transforaminal, interlaminar, or caudal injection techniques. Method: A comprehensive literature search was conducted using PubMed, Scopus, and the Cochrane Library, focusing on studies published within the last ten years. Inclusion criteria encompassed studies addressing lumbosacral radicular pain, the safety and efficacy of ESIs with different corticosteroid formulations, and comparative effectiveness analyses of injection routes. Data on corticosteroid types, formulation characteristics, adverse effects, efficacy measures, and patient demographics were extracted and analyzed both qualitatively and quantitatively. Results: Findings indicate significant variation in safety profiles and effectiveness among different corticosteroid formulations used in ESIs. Dexamethasone, often favored for its efficacy, has been linked to potential neurological complications, particularly concerning preservatives like benzyl alcohol. Comparative studies suggest that while dexamethasone may provide adequate pain relief, it may lead to higher rates of repeat injections compared to particulate steroids like triamcinolone. Conclusion: The review underscores the need for a personalized approach to ESI administration, balancing the benefits of pain relief against potential long-term complications. The data highlights a pressing need for ongoing research into optimizing corticosteroid use and ensuring patient safety in the management of lumbosacral radicular pain.
