“…Similar result is reported by Faiz and Steve [11], which stated that minimal amount of calcium carbonate was found most effective in increment of strength. Researchers have studied that certain concentration of bacteria increases compressive strength compared to control [4][5][6][7]. However, the concentration of bacteria depends on the bacteria itself.…”

Abstract. This paper presents compressive strength and water penetration of bioconcrete with addition of calcium lactate. Bioconcrete has higher engineering concrete properties and durability compared to normal concrete but the natural production of calcium carbonate is limited to the calcium content in cement. Therefore, additional calcium is added as an additional calcium source to study the influence towards compressive strength and water penetration. The bacteria used in this research are Enterococcus faecalis and Bacillus sp. Calcium lactate was added into concrete mix in concentrations of 0.001mol/l, 0.005mol/l and 0.01mol/l of liquid used. The concentration of bacteria added into the mix is by partial replacement of water used in casting, which are 3% for Enterococcus faecalisand 5% for Bacillus sp. Both compressive strength and water penetration test used cubes of 150mm × 150mm × 150mm. The cubes were tested after 28 days. The result of compressive strength for control is 36 MPa while partial replacement of bacteria yields 38.2 MPa for 3% Enterococcus faecalisand 37.0 MPa for 5% Bacillus sp. Calcium lactate with 0.005 mol/L has the best performance with 42.8 MPa for Enterococcus faecalis and 39.6 MPa for Bacillus sp. Whereas for water penetration, the best concentration of calcium lactate which yielded the lowest water penetration is 0.01 mol/l for both Enterococcus faecalis and Bacillus sp which are 8.7 cm and 8 cm respectively. The addition of calcium lactate into bioconcrete is quite promising for improvement of concrete properties and durability.

“…Bacteria that was known as Shewanella was isolated from the mud of the hot springs in West Bengal, India. This bacteria is used to improve concrete properties [5]. The use of Bacillus pasteurii and Pseudomonas aeruginosa which are endospore-forming soil micro-organism are used in Ramachandran [6].…”

Aim: The aim of this study was to estimate prevalence of hand osteoarthritis (HOA) and identify patterns in female patients with symptomatic primary knee osteoarthritis (KOA) presenting in a rheumatology outpatient department (OPD). Methods: A hospital-based cross-sectional study was done among 145 female patients with primary KOA, as per American College of Rheumatology (ACR) criteria, utilising the right knee as the index knee. The presence of Kellgren–Lawrence (K-L) grade ≥2 radiological changes in two of three groups of hand joints in dominant hand was used to identify hand arthritis (HOA). Symptomatic HOA (SHOA) was defined as existence of hand discomfort within preceding month. Hand disability was measured using the Health Assessment Questionnaire (HAQ); a mean score of >0.5 was deemed to be a significant disability. Global Hand Kellgren–Lawrence Score (KLTOT) was used to assess radiographic severity of HOA. Results: The prevalence of HOA was found in 96 (66%) patients, with a higher prevalence in patients above 60 years of age. At the individual joint level, 102 (71.7%) patients had DIP involvement, 96 (66.2%) had PIP involvement, 40 (27.5%) had metacarpophalangeal (MCP) involvement, and 57 (34.4%) had involvement in the base of the thumb. SHOA was found in 48 (33%) patients, and significant disability was noted in 38 (26.2%) patients. There was a significant positive correlation between global KLTOT and body mass index (BMI) ( P = .004) and between global KLTOT and HAQ ( P = .002). A significant difference was found between HOA and the radiographic severity of the KOA ( P = .003) in comparison to patients without HOA. Conclusion: HOA is common in elderly women, especially those with primary KOA.
