This paper presents an application of the wave equation to the
problem of selecting a driving hammer for prestressed concrete piles.
The potentially damaging effects of these types of hammers on various
prestressed concrete piles were analyzed by means of parametric
studies carried out on a hypothetical group of problems...
This study investigated the relationships between motivation for
sewing and: amount of sewing, perceived depersonalization of the job,
and creativity among employed women. Sewing for creativity and
sewing for economic reasons were the two motivations investigated.
Previous studies indicated that sewing for economic reasons was the

A study was conducted in summer of 1973 to assess impact of fluoride-insect damage on radial growth of lodgepole pine near the Anaconda Aluminum Company at Columbia Falls, Montana. Statistically significant growth losses attributed primarily to the effects of fluorides were found in 40 14 of 17 unmanaged stands for...
The development and maintenance of a family achievement
theme was analyzed using two dramas: Long Day's Journey Into Night
by Eugene O'Neill and A Death of a Salesman by Arthur Miller. Three
propositions were tested: 1) The development of a family achievement
theme involves a transaction between individual personality needs...
This paper presents a method of predicting penetration
resistance for driven piles, using known driving records for driving
the same type piling in similar subsurface conditions. As known
driving records are not always available to the analyst, a method was
also investigated using soil data only. The analytical tools employed...
