The non-permissible (NP) fluoride samples (in percentage) were obtained after overlaying the surveyed ground sampled points in all the different classes of each theme which were then given weightage according to weighted sum method (WSM), in the range 1 10, according to their percentage of fluoride contamination.

The values of different water quality parameters and percentage samples falling beyond the permissible limits as per WHO and BIS are given in Table 2.
Among choices that a user should be able to make are: (i) permissible degree of overlap of blocks; (ii) acceptable percentage of dropped markers; and (iii) granularity.
Metal specific EDIs revealed that EDI of Cr (for brand cow milk: 0.413 mg/day, for dairy farm cow milk: 0.243 mg/day and for domestic cow milk 0.352 mg/day) exceeded the permissible value (0.2 mg/day) and possess the highest concentration percentages to permissible value.
On the subject of cheating, it can be seen that most students preferred to remain neutral, with only a small percentage admitting to academic dishonesty or whether cheating is permissible if there are no repercussions.
In the present study the high percentage of food crops and fruits that violated the permissible limits of lead and cadmium as set by WHO, EU and EPA respectively is of public health concern.
To attribute constitutional significance to this figure, moreover, would lead to the absurd result that a neutral school-choice program might be permissible in some parts of Ohio, such as Columbus, where a lower percentage of private schools are religious schools.
It is also observed that the percentage of voltage and current THD of the proposed scheme is within permissible limits, indicate that the power quality of the inverter is not degraded by the proposed control strategy, and thus overcomes the drawback of existing active anti-islanding techniques.
The calculated values of sodium percentage of the groundwater samples indicate that 70%% of the samples fall in permissible limit except few samples falling under doubtful category according to the Wilcox (1955) water suitability classification for irrigation purpose.
