A Synchronous undifferentiated nasopharyngeal carcinoma and infiltrating ductal carcinoma of the breast successfully treated with induction chemotherapy followed by local control of both tumours: a case report

<p>Abstract</p> <p>Background</p> <p>Multiple primary cancers have a low incidence particularly when cancers are synchronous. Few cases of synchronous head and neck cancer and breast carcinoma are reported in the literature.</p> <p>Case presentation</p> <p>We report here an exceptional case of a 47 years old Moroccan woman presenting two synchronous cancers, the first in the nasopharynx and the second in the breast. The patient was treated successfully with a combined strategy associating chemotherapy, radiation therapy, and surgery. She remains disease free after 27 months of follow up.</p> <p>Conclusions</p> <p>Treatment strategy in the case of multiple primary cancers remains controversial because of the variety of presentations; initial aggressive treatment reports good results.</p

Оптимизация конструкции захвата для детали «Барабан»

Грузозахватные приспособления обычно применяются при производстве работ по подъему и перемещению грузов с применением грузоподъемных машин. Использование приспособлений позволяет реализовать максимальное удобство и безопасность производственного процесса. Грузозахватные приспособления конструируются для определенного этапа технологического процесса, для конкретного изделия. При проектировании таких приспособлений необходимо учитывать основные показатели оптимальности конструкции: прочность, надежность, простота, удобство и безопасность при эксплуатации, эргономичность. Кроме того, нужно стремиться к наименьшей массе и, соответственно, металлоемкости захвата. Конструкция грузозахватного приспособления, в основном, будет зависеть от назначенных технологом поверхностей, за которые можно крепиться и от максимальной высоты подъема крюка крана. В статье описана задача по конструированию захвата для детали «Барабан¬ в новом технологическом процессе. Рассмотрена конструкция существующего захвата, взятого за прототип. Приведен анализ различных вариантов конструктивных решений, созданных в процессе проектирования. Выбран вариант конструкции захвата, который в наибольшей степени соответствует требованиям технического задания. Конструкция этого модернизированного приспособления представляет собой захват с тремя лапами, удерживающими деталь, и подвес в виде траверсы. Разработанная конструкторская документация утверждена производством и отделом промышленной безопасности

Communities of Practice in non-industrial private forestry

Increasing uses of forests, such as bioenergy and biodiversity protection, are challenging family forest owners’ knowledge acquisition and decision making in Finland and elsewhere. Forest owners are also becoming economically less dependent and spatially estranged from their forest properties. Simultaneously, publicly funded forestry guidance calls for improved efficiency. Advisory practices need new ways to reach forest owners and to encourage them for forestry decisions that are conformable to their forest use goals. A potential model to diversify and renew guidance are Communities of Practice (CoPs). In CoPs forest owners, possibly together with experts, gather around an interesting issue, share their experiences and learn from each other. Learning from peers who are or have been in similar situations could be a relevant supplement to expert-driven guidance. This study aims to find out if CoPs exist in family forestry in Finland. To be able to identify them we search for the basic elements of CoPs: domain, community and practice. Additionally, we study the possibilities to strengthen or even create new CoPs. The data were gathered via seven focus group interviews, reaching 44 interviewees. Four groups consisted of local forestry professionals and one group consisted of national forestry extension developers. In addition, there were two different forest owner groups. Discussions in the groups considered communication between forest owners and professionals as well as the communication between owners. In addition, contexts, benefits and drawbacks of learning from the experiences of ‘similar others’ were discussed. Discussions were taped and transcribed. Qualitative content analysis will reveal the existing CoP-type features within private forestry in Finland. Particularly, which issues are dealt with and how, what kind of information is exchanged and who are involved? Furthermore, the promising elements and barriers of CoPs, as well as the possible role of forestry professionals in supporting CoPs, will be discussed
