Attention deficit hyperactivity disorder (ADHD) is of great importance not only in children but also in adults; however, despite extensive research there are still many unsolved questions with respect to the diagnosis. Patients not only suffer from attention deficits and hyperactivity but also a variety of other problems, such as dyspraxia, problems with stimulus discrimination, dysgrammatism, legasthenia, or motor coordination problems. Furthermore, there are also psychopathological disorders, such as problems with memory, formal thinking, emotional modulation, drive and vegetative stability, in the sense of a psycho-organic syndrome. Such syndromes have long been known in psychiatry under terms, such as complex capacity disorders, minimal cerebral dysfunction (MCD), minimal brain dysfunction (MBD), mild psycho-organic syndrome, psycho-organic axis syndrome, mild cognitive impairment, developmental disorder and developmental biological syndrome. Etiological data with respect to genetics and early childhood brain trauma support the notion of a psychobiological disorder for complex cerebral dysfunction in the sense of a psycho-organic syndrome. Depending on the individual life and work situation, these additional symptoms of ADHD are in many cases of greater relevance for life adjustment than the core symptoms, depending on the individual life and work situations. The concept of minimal cerebral dysfunction describes the ADHD problem better and has a direct bearing on the diagnosis, therapy and sociomedical care of the patients. [ABSTRACT FROM AUTHOR]

The present paper describes the production of lead zirconate titanate (PZT) with different additives and of lead metaniobate (PN) by means of the Thermal Two-Stage Process. This process, especially developed for the synthesis of multicomponent ceramic powders is characterized by the following: the starting constituents are liquid metalorganic precursors, such as alcoholates or acetates, which are converted to a homogeneous, multicomponent ceramic powder by spray drying the liquid precursors, resulting in an organic granulate, which is then followed by the thermal conversion of this organic powder into the final ceramic material. The resulting ceramic powder shows favourable properties with respect to homogeneity and further processing, e.g. pressing and sintering of compacts. The efficiency of the process will be demonstrated by the characterization of the piezoelectric properties of the sintered compacts. [ABSTRACT FROM AUTHOR]

The energy dependence of the proton polarization P has been measured for a fixed reaction angle of 52 degrees by p-He elastic scattering. P varies rapidly with the deuteron energy E. The experimental results are in good agreement with the assumption of a J = 1 level of the compound nucleus N at 11,23 MeV ( E= 1,13 MeV). [ABSTRACT FROM AUTHOR]

The reaction Li (p, α) He has been investigated with polarized protons using the reaction C(d, p) C as a proton polarizer. The right-left asymmetry R under 45 degrees was found to be less than 0,5. The case R=0 for all proton energies is not excluded. [ABSTRACT FROM AUTHOR]
