ПОИСК Закрыть Поиск ЮНИСЕФ Fulltext search Max Пресс-релиз Ежегодно около 19 миллионов новорожденных подвергаются риску поражения мозга из-за дефицита йода ЮНИСЕФ и GAIN призывают к немедленным действиям по расширению доступа к йодированной соли на фоне давних данных о том, как дефицит снижает когнитивные способности 02 Март 2018 Доступно на: English русский türkmençe По данным нового совместного доклада Детского фонда ООН (ЮНИСЕФ) и Глобального альянса по улучшению питания (GAIN) ежегодно здоровье 14 процентов новорожденных по всему миру, а это примерно 19 млн. малышей, подвергаются риску необратимого, но предотвратимого поражения мозга и снижения когнитивных функций из-за дефицита йода в первые годы жизни. (...) Гарретт, директор по продовольственной политике GAIN. “Благодаря совместным усилиям правительств, промышленности, гражданского общества, ЮНИСЕФ, GAIN и других организаций мы находимся на пороге обеспечения стабильного потребления йода всеми детьми. (...) ЮНИСЕФ и Глобальный альянс по улучшению питания (GAIN) уже на протяжении 10 лет осуществляют совместную работу в борьбе с дефицитом йода.

NOTE VERBALE DATED 2007/02/20 FROM THE PERMANENT MISSION OF THE REPUBLIC OF TURKEY TO THE UNITED NATIONS OFFICE AT GENEVA ADDRESSED TO THE OFFICE OF THE HIGH COMMISSIONER FOR HUMAN RIGHTS
In paragraph 20 of the report it is stated that “some lawyers did, however voice the concern that in some instances of crimes related to terrorism, the possibility for the defence to gain access to documents related to prosecutions is in practice restricted”. 20. The authority of defence lawyers to gain access to and examine case files, has been ensured in Article 153 of the Criminal Procedure Code No. 5271. According to this article, defence lawyers have the authority to gain access to case files and obtain copies of documents contained therein, free of charge, during the investigation.
