The study which aimed at determining the effect of malaria on pregnancy was conducted among pregnant women using peripheral blood and microscopy in Obio/Akpor Local Government Area of Rivers State.. The study was carried out between September 2022 and November 2022. A total of three hundred pregnant women were sampled for malaria parasites infection using thick and thin film smears. The result showed a prevalence of 21.66% (65/300). It was found that women in their first pregnancy had the highest prevalence of 35.0% (35/100) with age range of 26 – 30 years. Highest prevalence of 11.66% (35/300) was also recorded among women in their first trimester. Haematological parameters were analyzed using standard methods. Overall, the moderate reduction in haemoglobin concentration and packed cell volume (PCV) in patients were higher in second and third trimester than the first trimester with a lower level (p>0.05). There was no significant differences observed in the subjects with respect to the trimesters. There was a significant rise in neutrophils and a decrease in lymphocytes in all subjects irrespective of the trimester. The raised neutrophils count is attributed to febrile conditions that accompanies malaria especially in pregnant women. It is deduced that most of the cases of malaria observed from the study is due to unverified presence of malaria parasite at the time of antenatal registration. In line with this, it is therefore recommended that pregnant women adhere to prophylasis where necessary to reduce the possible effects of malaria in pregnancy. There is also need for people need for public enlightenment periodically.

The silica content, expressed as a percentage by the mass of SiO₂. ASTM-D-501 Gravimetric Method Section 51. Standard Method specifies a gravimetric method for the determination of the silica content of ceramacoat thinner. This gravimetric test method covers procedures for the chemical analysis of silica content (SiO₂) in Ceramacoat 512-T Thinner. In this study. Percent silica content has been determined successfully. The results of the gravimetrically determination of silica in Ceramacoat sample were %23.63, and %23.37 in respectively. Percent Standard Deviation is % 1.56.

Chromium and Fluorine Insolubilize Agents and a Treatment Method on Biomass Incinerated Ash

Thu, 04 Sep 2025 00:00:00 +0100

Biomass incinerated ash sometimes contains hazardous substances such as hexavalent chromium and fluorine, which poses an obstacle to recycling. In order to remove or insolubilize these harmful substances, aqueous solution of Iron (II) sulfate and mixed solution of sulfuric acid and calcium hydrogen phosphate were added to the incineration ash. In order to thoroughly detoxify the ash, we devised a method in which an excessive amount of treatment liquid is added to the ash, and the surplus water generated is used for monitoring or reused as treatment water. This made it possible to reduce the harmful substances in the ash to below the environmental standard value in a short time.

Comparative Cytomorphological Analysis on Liquid PRFs Produced with DUO Fixed Angle Centrifuge and Oscillating Centrifuge

Thu, 18 Sep 2025 00:00:00 +0100

Background: Liquid PRF is an injectable second-generation platelet concentrate rich in platelets, leukocytes, and fibrinogen obtained by centrifugation of autologous blood. Methods: This study aimed to analyze the cellular and fibrinogen content of various types of liquid PRF (C-PRF liquid, A-PRF liquid, i-PRF, liquid fibrinogen) obtained using a swinging centrifuge with Vacumed FL tubes (code 44909) compared to that obtained with a fixed-angle centrifuge DUO and the original S-PRF Sticky tube. This study found that the average accumulation of thrombocytes was approximately 1.5 times higher than that observed in whole blood. Due to the high concentration of platelets and leukocytes, liquid PRFs contain important growth factors for tissue regeneration. Results: In this definitive study we have highlighted that with the use of the Oscillating centrifuge, the type of Liquid PRF with the highest content of Platelets (133.1% vs 122.9%) is the A-PRF liquid (1300 rpm × 5'), the one with the highest content of Monocytes (142.9% vs 125.0%), with a sufficient content of Lymphocytes (220.0% vs 198.7%), Neutrophil Granulocytes (54.0% vs 58.8%) and Fibrinogen (97.1% vs 104.3%), is the i-PRF (700 rpm × 5 min) obtained with the Vacumed FL tube (code 44909) with statistically insignificant differences compared to those obtained with the S-PRF Sticky test tube, while the content of Fibrinogen present in C-PRF (2500 rpm × 8') is higher (104.0% vs 106.5%) obtained with the with S-PRF Sticky tube with a significant difference (p=0.013). Cellular score was also calculated, finding that the type of liquid PRF with the highest score was i-PRF (700 rpm × 5’) extracted with a Vacumed FL tube in a rocking centrifuge (127.17%). Conclusions: Values were significantly higher than those obtained with the Fixed Angle Centrifuge and with the S-PRF Sticky tube. However, when calculating the cellular score, the highest result, equal to 127.2%, was obtained with i-PRF (700 rpm × 5’) with Vacumed FL tube and Oscillating Centrifuge.

Electrical Properties of Silicon Nanowire MOS Device

Ravi Kumar Chanana — Fri, 12 Sep 2025 00:00:00 +0100

In this research article, the electrical properties of a 1nm diameter Silicon nanowire MOSFET are calculated utilizing the universal mass-energy equivalence relation for the semiconductors to find the intrinsic Fermi energy level in the bandgap below the Silicon conduction band. The conduction band offset, Fowler-Nordheim electron tunnelling onset field, leakage current density in the oxide at FN onset field, the electrical oxide breakdown field, the total interface trap density, and the average channel electron mobility are all surveyed and calculated theoretically. The determined properties suggest robustness of the SiNW MOS device.

Role of Leadership Style in Project Success a Case Study of Development Projects

Khalid Ismail Ali — Fri, 19 Sep 2025 00:00:00 +0100

The success of development projects largely depends on effective leadership, yet many projects worldwide continue to fail, resulting in significant financial and operational losses. Leadership style plays a critical role in influencing project outcomes by shaping team performance, resource utilization, and stakeholder satisfaction. Despite the extensive global literature on leadership and project management, there is limited empirical evidence from Somaliland, particularly in Hargeisa, where development projects are increasingly implemented. This study seeks to critically examine the role of leadership style in the success of development projects in Hargeisa. A descriptive research design was adopted, targeting a population of 80 respondents, including program managers, project managers, project officers, administration officers, and finance officers. Using Slovene’s formula, a purposive sample of 63 participants was selected. Data was collected through semi-structured interviews and questionnaires, complemented by secondary sources such as books, reports, and published studies. Both qualitative and quantitative methods were applied in data analysis, with the aid of the Statistical Package for Social Sciences (SPSS). Findings from this study are expected to provide insights into the understanding of leadership in project management, identify the most effective leadership styles for project success, highlight essential leadership skills, and explore key challenges in managing development projects in Hargeisa. The research contributes to filling the literature gap in the local context, while offering practical recommendations for policymakers, project managers, and development organizations to improve leadership practices and enhance project success rates.
