Q. Is it safe for teenagers to use weight loss products? This isn't an ethical question, but quite literally asking if it is safe for a teenager to use weight loss solutions like weight loss milkshakes and other things of that nature. Thanks in advance!

A. From health point of view- there shouldn’t be a problem if those products are safe. But from an educational view- the minute you start relaying on weight loss products to loose weight for you- you become lazy. Then you’ll loose weight and gain it back with some extra. You need to start acquiring good habits while you are young- balanced nutrition and sports.

And global Malmquist productivity index on T G is defined as:
Characteristic of separate indexes at determination of the land productivity potential: a) For evaluation of the productivity indexes (phytomass and productivity) of the ecosystems of river basins, we used electronic maps of the land management structure, which are composed by decrypting satellite images (usage of materials of surface shooting is also possible).
Based on multi input-output frontier representations of the production technology [28], the Malmquist productivity index has many advantages.
Via research developments, it has been shown that the technical change has effect in productivity, too, and the Malmquist Productivity Index (MPI) was introduced by Malmquist in 1953 [6].
Our study aims at analysing the productive efficiency across different sectors of Lithuanian economy by the means of the Malmquist productivity index. It is worth to be noted, that the latter method has not been applied for analysis of the Lithuanian economy.
However, when the wheat plant productivity index was plotted over N rates, the non-linear relationship showed that N fertilization at 80 kg N ha-1 accounted for 85% of the variability in the plant productivity under DT and HS while ZDT had the same productivity at 120 kg N ha-1.
