Hace 9 horas · The sensitivity was measured at 0.890 μA μM−1 cm−2 within the concentration range of 25.0–800 μmol L−1 and 8.87 μA μmol−1 cm−2 within the range of 0.10–10.0 μmol L−1. The device demonstrated stable and satisfactory recovery rates between 96.56% and 103.88% when detecting BPA in various plastic samples, highlighting its ...
Hace 3 días · This calculator subtracts two fractions. First, convert all fractions to a common denominator when fractions have different denominators. Find Least Common Denominator (LCD) or multiply all denominators to find a common denominator. When all denominators are the same, simply subtract the numerators and place the result over the common denominator.
Hace 4 días · The aim of this meta-meta-analysis was to systematically review randomised controlled trial (RCT) evidence examining the effectiveness of e- and m-Health interventions designed to improve physical ...
Hace 9 horas · A study on photosynthetic and enzyme activity changes and mineral content in lettuce under cadmium stress has been conducted in a greenhouse, utilizing the modulated effect of zinc (Zn) application in the nutrient solution on lettuce. Zn is a micronutrient that plays an essential role in various critical plant processes. Accordingly, three concentrations of Zn (0.022, 5, and 10 mg L− 1) were ...
Hace 1 día · Background Obesity may increase surgical complexity in patients undergoing abdominal surgery by limiting visualization and increasing the risk of peri-operative complications. A preoperative reduction in weight and liver volume may improve surgical outcomes. The aim of our study was to evaluate the efficacy of a low-calorie diet (LCD) versus a very low-calorie diet (VLCD) in reducing weight ...
Hace 9 horas · The tetrathiovanadate [VS 4] 3− is analogous to the orthovanadate ion. [31] At lower pH values, the monomer [HVO 4 ] 2− and dimer [V 2 O 7 ] 4− are formed, with the monomer predominant at a vanadium concentration of less than c. 10 −2 M (pV > 2, where pV is equal to the minus value of the logarithm of the total vanadium concentration/M).
