My Happy Baby is Back: Zero Balancing, CranioSacral Therapy and a Baby’s Journey to Becoming Mobile
Alison began receiving ZB and CST at 13 months of age due to gross motor delays: at that age she was only able to sit somewhat rigidly. After the first session, Alison changed` from being very unhappy and seemingly frustrated to being happy and more calm. Within one month of weekly sessions, Alison was able to be on her tummy, began to crawl, became more agile in seated play, was squatting and standing and took her first steps
Communication for social change : seldom a stand alone, and rarely verified
Communication for social change is rarely a stand-alone initiative. It is often combined with multiple communication purposes, like networking, organizational visibility, information dissemination, or behavioural change. The article reports on an inter-disciplinary, capacity building experiment that combines communication strategy development with Utilization-Focused Evaluation (UFE). An external evaluation of the DECI-2 project observes that the combined decision-making process enabled partners to become better at adaptive management
Functional activity in the endochrines: the physiological and pathological significance of the histological findings
Treatment by methods of grafting or transplantation is becoming better understood, and there is
little reason to doubt that this line of treatment,in
cases of endocrine deficiency, will become established presently on a sound basis. Recent experience has
shown that in the suprarenal deficiency of Addison' s disease - so long intractable to any form of treatment -
there is every hope of obtaining curative results by
grafting, if the graft is embedded in a suitable position.Within recent years the endocrines have advanced
rapidly in surgical interest. Great strides have
been Lade, not only in the direction of a better
understanding of' the biochemistry of the principal
glands, but also in the treatment of their diseases
by surgical measures. The principal hormone of the
thyroid appears to have been isolated and to have
been produced synthetically by Kendall, and the work
of Plummer, Goetsch, and Wilson, has done much to
elucidate the pathological affections of this gland.
Brailsford Robertson believes that he has succeeded '. isolating the active principal of the anterior lobe o the pituitary. In the direction of surgical therapy,
the scientific method and careful technique of CrÃle,
Mayo, Judd, and others in their work on the thyroid
gland has been followed by the most happy results,
more especially in the treatment of the various forms
of toxic goitre. Operations on the pituitary,especiel
ly in the hands of Frazier & Adson, have been followee
by much greater success than formerly.Knowledge still lags,however,in the case of many
of the endocrines,both in regard to their physiology
and their pathology. The function of the pineal gland
is largely a matter of conjecture,the fate of the secretion óf the posterior lobe of the pituitary is still
under discussion,and much remains to be learned of the
function of the pa.rathyroids and of the suprarenal
cortex.The object of the present investigation is to examine the principal endocrines in a state of functional activity, comparing the appearances with those of the
organs in a ouiscent state,and to consider the bearing
of the signs of secretory activity of the healthy gland. on the physiology and also on the pathological affections in each case.It is well known that in certain states of the
organism, especially those of excessive sympathetic
excitation ,such as occurs in rage or fright, as shown
by Cannon,and at certain periods of life - dentition,
puberty, menstruation, and pregnancy - there is an excessive demand on the activities of the endocrine
organs. These activities reach their zenith in pregnancy, which condition throws a greater strain on the
organism than any other physiological process. It is
becoming increasingly evident that in pregnancy there
exists a condition of pluri-glandular activity in which
all, or the majority, of the endocrines are functioning more actively than normal. a comparison of the
histological appearances in non -pregnant and pregnant
animals is therefore likely to show certain differences between the resting and the active phases of
endocrine tissues.In order to examine the finer details of cell
structure it is necessary to obtain an immediate
coagulation of the living protoplasm. It is only by
immediate fixation of the tissues from newly- killed
animals that a satisfactory result can be obtained.
A specimen from a healthy human subject at the desired
periods is rarely, if ever, available, and the tissues
examined after death from infective or toxic causes
are practically valueless from the point of view of
the study of the normal organ or tissue. Even in
cases of death of healthy subjects from injury there
is inevitably delay in obtaining and fixing the
tissue, and in the interval secretion products disappear and extensive degenerative changes may take
place in the cell protoplasm.In the present research the animals employed
have been healthy guinea -pigs and rabbits. The
guinea -pig has been a specially suitable subject for
examination, the principal endocrine glands being all
of large size and easily discovered and stained.
Elliott & Tuckett have shown that this animal possesses
a larger suprarenal in proportion to its size than
any other of the usual laboratory animals. The same
probably holds good with regard to the thyroid and
the thymus. Tissues from the human subject have also been examined in certain cases, but owing to the delay
between the time of death and the fixation of the
specimen, the results, as a general rule, have been
less satisfactory than in animals. In the case of a
few operation specimens, however, it was possible to
fix the tissue while it was still warm, and these
specimens gave good histological results

Horizontal Shear Wave Imaging of Large Optics
When complete the National Ignition Facility (NIF) will be the world's largest and most energetic laser and will be capable of achieving for the first time fusion ignition in the laboratory. Detecting optics features within the laser beamlines and sizing them at diameters of 0.1 mm to 10 mm allows timely decisions concerning refurbishment and will help with the routine operation of the system. Horizontally polarized shear waves at 10 MHz were shown to accurately detect, locate, and size features created by laser operations from 0.5 mm to 8 mm by placing sensors at the edge of the optic. The shear wave technique utilizes highly directed beams. The outer edge of an optic can be covered with shear wave transducers on four sides. Each transducer sends a pulse into the optic and any damage reflects the pulse back to the transmitter. The transducers are multiplexed, and the collected time waveforms are enveloped and replicated across the width of the element. Multiplying the data sets from four directions produces a map of reflected amplitude to the fourth power, which images the surface of the optic. Surface area can be measured directly from the image, and maximum depth was shown to be correlated to maximum amplitude of the reflected waveform
