Measures of prevention and control against polycyclic aromatic hydrocarbons (PAHs) focus on an official food control, a code of best practice to reduce PAHs levels by controlling industry and in the development of a chemopreventive strategy. Regulation (EU) 835/2011 establishes maximum levels of PAHs for each food group. In addition, Regulations (EU) 333/2007 and 836/2011 set up the methods of sampling and analysis for its official control. Scientific studies prove that the chemopreventive strategy is effective against these genotoxic compounds effects. Most chemopreventive compounds studied with proven protective effects against PAHs are found in fruit and vegetables.

The influence of bottom topography on the distribution of temperature and salinity in the Indonesian seas region has been studied with a high-resolution model based on the Princeton Ocean Model. One of the distinctive properties of the model is an adequate reproduction of all major topographic features in the region by the model bottom relief. The three major routes of flow of Pacific water through the region have been identified. The western route follows the flow of North Pacific Water through the Sulawesi Sea, Makassar Strait, Flores Sea, and Banda Sea. This is the main branch of the Indonesian Throughflow. The eastern routes follow the flow of South Pacific water through the eastern Indonesian seas. This water enters the region either through the Halmahera Sea or by flowing to the north around Halmahera Island into the Morotai Basin and then into the Maluku Sea. A deep southward flow of South Pacific Water fills the Seram Sea below 1200 m through the Lifamatola Passage. As it enters the Seram Sea, this overflow turns eastward at depths greater than 2000 m, then upwells in the eastern part of the Seram Sea before returning westward at ~1500-2000 m. The flow continues westward across the Seram Sea, spreading to greater depths before entering the Banda Sea at the Buru-Mangole passage. It is this water that shapes the temperature and salinity of the deep Banda Sea. Topographic elevations break the Indonesian seas region down into separate basins. The difference in the distributions of potential temperature, ?, and salinity, S, in adjacent basins is primarily due to specific properties of advection of ? and S across a topographic rise. By and large, the topographic rise blocks deep flow between basins whereas water shallower than the depth of the rise is free to flow between basins. To understand this process, the structure of simulated fields of temperature and salinity has been analyzed. To identify a range of advected ? or S, special sections over the sills with isotherms or isohalines and isotachs of normal velocity have been considered. Following this approach the impact of various topographic rises on the distribution of ? and S has been identified. There are no substantial structural changes of potential temperature and salinity distributions between seasons, though values of some parameters of temperature and salinity distributions, e.g., magnitudes of maxima and minima, can change. It is shown that the main structure of the observed distributions of temperature and salinity is satisfactorily reproduced by the model throughout the entire domain.

La responsabilitat de les fam??lies, concretament de les dones, pel que fa a la cura de les persones dependents generalment s???ha ent??s com una tend??ncia natural d???algunes societats tradicionals en qu?? valors com la solidaritat dins l?????mbit privat s???imposen sobre la protecci?? p??blica. Aquest argument est?? relacionat amb el model familista d???estat de benestar propi del sistema de protecci?? espanyol i del estats del sud d???Europa. Des d???una perspectiva diferent, m??s que d???una opci?? es tractaria d???una obligaci?? que recau sobre les fam??lies, a causa d???un sistema ocupacional que no facilita a aquestes ocupar-se dels seus membres i d???un sistema p??blic insuficient. Concretament, en relaci?? amb el paper que assumeixen els padrins en aquestes relacions de solidaritat familiar, al treball es presenten dades que mostren que als pa??sos del sud la freq????ncia en la cura dels padrins als n??ts ??s m??s baixa per?? la cura ??s m??s intensiva. Aquests estudis confirmen que un estat del benestar fort amb un grau elevat de cobertura social no redueix la solidaritat familiar. La inversi?? en pol??tiques familiars afavoreix la solidaritat intergeneracional, en tant que permet una complementarietat entre l???ajuda p??blica i l???ajuda familiar, sense esgotar ni saturar la darrera. A la inversa, la manca o un nivell molt baix d???inversi?? en pol??tiques familiars pot fer m??s prec??ria l???ajuda.

L’article 31 de la Convenció sobre els Drets de l’Infant estableix que «l’infant té dret a l’esplai, al joc i a participar en les activitats artístiques i culturals». D’aquí que resulti important que el joc infantil i la jugueta siguin uns mitjans que aportin idees, que fomentin la creativitat i que eduquin per als valors ciutadans i socials (educar per a la pau i no per a la violència, saber compartir, comprendre el món que ens envolta, respectar els altres, etc.), en aquesta publicació es presenten pautes i referències per a famílies per donar a conèixer la importància del joc i orientacions generals per els pares a l'hora de seleccionar les joguines.
