Tabloid press

Tabloid Press.—When the substance under investigation is a solid, it will be found very convenient to compress it into a short rod or tabloid, in which form it can be readily weighed and introduced into the freez- 

After carefully cleaning these different parts, the end of the cylinder is closed by the stopper, b, and the collar c is then placed in position over the other end of the mould. The substance to be compressed is placed, in small quantities at a time, inside the collar and gently pressed down the mould by means of the plunger. When a sufficient quantity of the substance has been introduced, the plunger is placed in the 

When the substance has been sufficiently compressed, remove the mould from the press, detach the stopper b, place the collar over this end of the cylinder, and, inserting the plunger again in the mould, place the whole once more in the press and force the rod of substance out (Fig. 45). 

After use, the mould and plunger must be well cleaned (if necessary, with the help of a solvent), dried and oiled before being put away. 

Two further additions of the substance should be made, and the freezing-point of the solution determined after each addition. From each set of determinations, calculate the molar weight of the solute. The error should not exceed 3-5 per cent.

Before describing the chief methods by which the molecular weight of an organic compound in solution may be determined, a description is given of the Beckmann thermometer, and of the Tabloid Press, both of which are frequently used in the above determinations. 

Where a tabloid press is not available, the substance may be shaken out from a narrow tube inserted through D. This method is, indeed, best in the case of cryoscopic measurements, on account of the time required for the solution of the compressed solid to take place. 

To get at good overview of contemporary daily press coverage of chemicals in Sweden and Poland, we have chosen to study texts from national newspapers, including one tabloid and one regional/local newspaper in each nation during an entire year (2007). A time frame of 12 months enables us to cover variations in interest for the subject and represents the kinds of content about chemicals that readers encounter in general. Because of difficulties in accessing media texts from Poland, we have extended the search period there to one and a half years (from January 2007 until June 2008). 

The search for media texts about chemicals in the Polish press revealed a corpus of 179 news and debate articles (including a few editorial comments). A clear majority of them was published in the national press (151 articles), not including the popular tabloid Fakt (only 7 hits). When analysing the major themes and recurrent topics... 

Let us now examine the accuracy and fairness of the British Press. The following recent example reveals the contrast between the broadsheets and the tabloids. From Today (July 24, 1993) ...
