Starter comparative evaluation

Table 10. Comparative evaluation of starter battery separators...

The above comparative evaluation of starter battery separators refers to moderate ambient temperatures the standard battery tests arc performed at 40 or 50 °C. What happens, however, on going to significantly higher temperatures, such as 60 or 75 °C This question cannot be answered without considering the alloys used batteries with antimonial alloys show a water consumption that rises steeply with increasing temperature [40], leaving as the only possibilities for such applications either the hybrid construction, i.c., positive electrode with low-antimony alloy, negative electrode lead-calcium, or even both... 

The individual starter battery separator systems have been described here they are evaluated comparatively. There are no standards for evaluating separators Therefore the comparison will be concentrated primarily on the effects on the performance of the starter battery, with other decisive criteria such as cost structure and effects on productivity indicated. 

In another study (Ewe et al. 2010), ten strains of Lactobacillus were evaluated for their viability and growth characteristics in soymilk supplemented with B-vitamin. These authors showed that the addition of B-vitamins promoted the growth of all the lactobacilli and also stimulated the synthesis of riboflavin and folic acid by lactobacilli in soymilk. Lact. acidophilus ATCC314 or Lact. acidophilus FTDC 8833, used as culture starters, increased riboflavin concentrations (657% and 243%, respectively) in soymilk, compared with its initial concentration prior to 24 h fermentation, whereas other strains, such as Lact. acidophilus FTDC 8833 and Lact. gasseri FTDC 8131, consumed this vitamin. These results confirm that riboflavin production/consumption is a strain-dependent trait.
