It attempts to begin with the industrial or tec: -iagir.il problem and throw light on it by discussing known practical methods and such theory as may unavoidable. Vibration measuring is now at the stage whereat Audio found itself about forty years ago. . . vas amount of measuring has been done in the paat decade or two, and a vast body of theory baa beer oroui rt to bear in seme areas. Neverthe* leas, the theoretical and measuring activities are still, aa it were, ae separate worlds, particularly as regards tb* vibratory end acoustic control of existing machine*. as d languished from design work. This present handbook trios to join the two worlds. It tries to form one br.dg* among the many that ar* still needed. The field ia vast, and so expanding that its progress outpace tb* capacity of writers to document it. For this reason, and aa will be noticed, the handbook ia simple a .election. But this lack is the natural result of starting to document a field like vibration measuring which b grown from almost nothing in a doeado dr two to a complete world that now includes maintenance, mec an*. design, ecology, transporta tion. space travel, and soon almost without and. Out of all the poeeit.e areas of specialisation, the pre sent book tends to focus on maintenance or on the well being and eeotxol of easting dtechines more than on anjrthing slae. Just aa an cflort is mad* to consider always the practical problem and the industrial need, every effort ia also made to address the maintenance engineer, toe informed technician, or any one who ia charged with the task of using vibration and acoustic msaauromanta in the day-to-day world of prac tice. Indeed it ia hoped that the industrial operator will find that the authors meet hie aia far as possible on hi* own ground and in his own terms. In its constant effort to accentuate the need and character of the sctiial field situation, the present handbook is unique. The first eleven chapters include seme of the funda mental* of acoustics and vibration together with what seemed to bo ecus of the mere useful highlights of aaaljrtieal methods end of vibration isolation. The next eight chapter* are devoted entirety to examples drawn bom the field of machine maintenance. In this field, vibration measuring covers the entire gamut from safety to economy of operation. Throughout, the topics of velocity measuring and of severity levels have beam given the prominence that their importance deserves. Seven more chapters ar* then devoted to miscellaneous measuring examplas and measuring instrumentation.

This observation was apparently attributable to the nan-athletes being five to ten years younger tban tbs former athletes.

This was beeeuee the consumption of large amounts of cyelamate increased the risk of bladder caaoeria rats. .Mew we are faced with the possibility that the use of saccharin might also be prohibited, and far reasons remarkably similar to these which led to the haa en eyriemates. Saccharin was in use many decades before regulations required the use of animal team to establish that a substance added tn feed is nets carcinogen. The first suspicion of bladder caretsogenidty came ia 1697 when workers at the Chester Beatty Institute in London reported the occurrence of one papilloma and three carrimanaa of the bladder in ados after tha intravesical implantation f pallets containing one part of saccharin to tour parts of cholesterol. This finding was later confirmed, but evidence of this kind was net sufficient to lead to tha banning of saccharin because it was arguable that irritattoa. attributable simply to the presence of solid pellets within the lumen of the bladder, night have contributed co-earanogenically to tbs development of tumors.

In general, the dam suprort the hypothesis that low status workers expect more'exempuons`from work when ill than high status workeri. If supported by further and more extensive research these findings will have; important implications They indicate that for whatever reeaoa deck of job eaoafacnon. or any one of sj host of other pdssilile reasons) Jew ststtM workers are net only more likely to do less work due to illness j than high status workers, but te1 advance of Illness they expect'to do teas work. In other words. g: -.- aame rate and degree of illness in s polulatwn of high status workers and low status workers one wuu.a pre dict that low status workers would cuss more work. This almost eouid be termed a cape of annmpetory xr- i capacity , or a case of aa.umpatoiy coping with an unfavorable job ainmtUm. This eoocluaion ia bolstered by the fact that the pattern bolds even when controlled for sex aad raoe. The pattsm appears to be more j pronounced during the acute stage of Illness. This may; have something to do with differences in the nature ; of work tsaks between fit low status and high status workers in .the sample. The jobs of tha low amtus workers roquire store physical mobility and manual dexterity than those of high status workers . Thus the ' low status werksramay perceive that they would bo Jape able to portent their work taakfiin the acute stage ! of illneee. While the magnitude of the relationship is not ee strong ia the convalescent stage of illness, it is j interesting m oots that the greetsst differences between the two groups is with heart condition. Here again j the explanation may be due to the diffarent nature of the job situation . The jobs of low statue workers may ( be perceived as demanding a greeter strain on the heart.
