Article Synopsis
  • * The study experimented with nanoparticles of Magnesium oxide (MgO), Calcium hydroxyapatite, and Zinc oxide (ZnO), finding that MgO nanoparticles produced the highest biodiesel yield of 61.5 mg/L.
  • * By enhancing cell activity, these nanoparticles can effectively increase lipid content in microalgae, suggesting that biostimulation techniques could be vital for improving biodiesel production.

Human activity recognition (HAR) is essential for the development of robots to assist humans in daily activities. HAR is required to be accurate, fast and suitable for low-cost wearable devices to ensure portable and safe assistance. Current computational methods can achieve accurate recognition results but tend to be computationally expensive, making them unsuitable for the development of wearable robots in terms of speed and processing power.

Article Synopsis
  • Bosworth ankle injuries (BAIs) are rare dislocations coupled with fractures that complicate treatment due to issues like fibular impingement, which can lead to prolonged swelling and the risk of compartment syndrome.
  • In a retrospective case study of patients aged 25-62, all presented with BAIs and underwent surgery after delays ranging from 2 to 49 days, with some requiring additional procedures like reverse talar dome osteotomy.
  • The study highlights the importance of early diagnosis for optimal treatment outcomes, noting that patients generally regained full mobility within 12 to 20 weeks post-surgery, depending on the severity and delay of their injuries.*

Unlike renewable energy sources, burning fossil fuels has severe environmental impacts, such as greenhouse gas (GHG) emissions and climate change. Therefore, this study was conducted to assess and compare the environmental impacts of three biogas utilization scenarios for energy production. The life cycle assessment (LCA) method was used to compare (i) biogas combustion in combined heat and power (CHP) unit, (ii) biogas burning in a steam boiler, and (iii) biogas upgrading using pressure swing adsorption (PSA) unit to determine the most sustainable option.

Bioenergy is a promising solution for greenhouse gas (GHG) emissions mitigation. However, the emissions resulting from the different production stages must be quantified and evaluated. The life cycle assessment (LCA) method was used to compare and quantify the environmental burdens of three rice straw (RS) utilization scenarios for producing biogas, briquette fuel, and syngas.

This work aims at developing a novel hyaluronic acid (HA) production method using magnetic nanoparticles (NPs). In a separate process, HA was produced with the addition of the amino acids (AA) as bio-additives. Regarding the NPs additives, the results showed that the highest dry weight of the produced HA was 0.

Distinct sequences of Giardia duodenalis assemblages raised the hypothesis that certain assemblages may contribute to its clinical outcome. However, sequences analysis is time consuming, expensive, and needs many manual operations. Nested PCR targeting intergenic spacer (IGS) region was applied successfully to genotype G.
