RESEARCH ON THE FERTILIZATION OF SWEET POTATOES ACCORDING TO THE NUTRITIONAL SPACE, IN THE SANDY SOIL CONDITIONS FROM ROMANIA

Research conducted during 2015-2017, in the climatic conditions of sandy soils in Romania, highlights the role of fertilization and plant density on the growth and development of sweet potato plants (Ipomoea batatas). The obtained results, show the positive implications of chemical and foliar fertilization on the physiological processes in the plant and on the quantity and quality of the obtained production. The fertilization of the sweet potato culture with N150P80K80, prior to planting and the use of a density of 50000 plants / ha led to a maximum yield of 27907 kg / ha. From the point of view of the quality of the production, the application of two foliar fertilizations with the product Timasol in a concentration of 1%, having N15P15K30 + 13 microelements, determined the increase of the biochemical components from the sweet potato tubers, compared to the only radicular fertilized

Medical Malpractice : How Legal Liability Affects Medical Decisions

In health care, overuse and underuse of medical treatments represent equally dangerous deviations from an optimal use equilibrium and arouses concerns about possible implications for patients\u2019 health, and for the healthcare system in terms of both costs and access to medical care. Medical liability plays a dominant role among the elements that can affect these deviations. Therefore, a remarkable economic literature studies how medical decisions are influenced by different levels of liability. In particular, identifying the relation between liability and treatments selection, as well as disentangling the effect of liability from other incentives that might be in place, is a task for sound empirical research. Several studies have already tried to tackle this issue, but much more needs to be done. In the present chapter, we offer an overview of the state of the art in the study of the relation between liability and treatments selection. First, we reason on the theoretical mechanisms underpinning the relationship under investigation by presenting the main empirical predictions of the related literature. Second, we provide a comprehensive summary of the existing empirical evidence and its main weaknesses. Finally, we conclude by offering guidelines for further research

The Influence of the Au Nanoparticles Dimension on the Photocatalytic Performances of TiO2−AuTiO_2-Au Porous Composites

The influence of Au nanoparticles dimension on the photocatalytic performances of the $TiO_2$ aerogels-Au composites was evaluated. Structural and morphological peculiarities of the $TiO_2$ aerogel, unloaded and loaded with 5 and 22 nm Au nanoparticles, were studied by transmission electron microscopy technique, X-ray diffraction and $N_2$-sorption measurements. UV-Vis diffuse reflectance measurements were performed to determine the band gap energies. The photocatalytic activity was evaluated by monitoring the salicylic acid photodegradation. It was found that the Au nanoparticles promote the anatase phase crystallization and produce the decrease of the specific surface area and band gap energy values. The porous composite with the smallest Au nanoparticles dimension exhibits the best photocatalytic performances
