Guessing
(1929)
The present paper deals mith the results of an environniental isotopic study in western Thessaly valley, carried out during the period 1968 - 1971. The isotopes used are 18O, D, Tritium, 18C and 14C. By the interpretation and evaluation of these resiilts useflil informations as regards the soiirce of recharge, the recharge mechanisrn and the dynamics of the flow system of the valley are provided.
In a joint enterprise, the ground water supplies in some Oases in UAR (namely El Kharga, El Dakhla, El Baharia and Siwa), in Wadi El Natrun (to the west of the Nile Delta), in Ayoun Mousa (West Sinai) and in some places along the Mediterranean Littoral, have been investigated. According to the dating of the water by the C14 method, the age of the artesian water from the Oases is between 25,000 and 40,000 years and the origin is obviously from rain water which fell and infiltrated within the "Nubian Sandstone" layers, occupying almost entirely the southern portion of the western Desert (the water underwent some evaporation before it disappeared in the subsurface as indicated from the loss of the 016). This process took place during one or more of the Pluvial periods which followed (and were not coincident with) the last "Würm" eustatic lowering of the Mediterranean. No infiltration water have presumably recharged the layers in question, so almost entirely fossil water reserves are tapped at present. The quantities of such reserves are unknown. More ancient waters, however, may be expected to the north of El Kharga and El Dakhla Oases. Such waters may- to their greater portions - enter these two oases from that direction. On the other hand, little or almost no water is expected to feed the reservoir from the opposite direction.

Some physical phenomena associated with the anxiety states and their relation to hyperventilation
(1937)
The authors believe that there is a physiological background for the perseverance of an anxiety state as part of a psychoneurosis; that this background is produced by the constant presence of purely emotional disturbances; and that the resultant physiological state aggravates the psychic component to such a degree that a vicioris cycle is instituted, the symptoms of which are manifold. These symptoms increase the severity of the emotional tension ; and, if they are prolonged, permanent structural change with the production of organic clisease results. The mechanism is at first a repetition of attacks, from the stimulation by an emotion such as fear upon the sympathetic nervous system, which in turn becomes increasingly labile. The mechanism is perpetuated by the effects of the simulus on the system of self-defense, which is dispatched by the endocrine group. This reaction causes a state of hyperirritability to exist through the presence of tissue alkalosis, tissue liydremia, and tissue anoxemia; and results in a state of tetany which may be regional or generalized. The Symptoms of tetany, and allied rnanifestations such ac tachycardia, distended stomach and dilated urinary bladder, are enough to aggravate the neurosis because of the patient's fear of impending dissolution. Multiplication of impulses increases the bombardment of the sympathetic nervous system, making repetition of tlie reaction more easy at subsequent intervals. The cure is accomplished through elimination of tlie fear-impulse by psychotherapy. The symptoms may be alleviated medically, and by this rneans that part of the neurosis which is on the basis of anxiety concerning health may be eliminated. Because of the subjective and objective improvement in the patient's condition, contact for psychotherapy is more easily obtained. Medical treatment is directed toward preservation of the acid-base balance; toward decreasing the effect of adrenalin on the nerve-tissue by means of a known chemical antagonist; or toward converting the state of tone of the individual from extreme to moderate, whether parasympathic or sympathetic in type.
