The geographical distribution of Ophelia bicornis is restricted to the coasts of the Mediterranean Sea, the Black Sea and the western coast of Europe as far as Brittany and southern parts of Great Britain. Within this wide reach, the worm is restricted to very narrow areas (in the context of the rise and fall of the tide) of sand which are generally unsuitable for sustaining populations of animals and plants. Despite this, Ophelia is shown to succeed and flourish there, depending, to a large extent, on physical and physiological adaptation.

Darlith ar dirwedd symudol Ynys Môn a draddodwyd gan Dr Dei Huws, Ysgol Eigioneg Prifysgol Bangor, i Gymdeithas Wyddonol Gwynedd ym mis Rhagfyr 2017. Gellir gwylio'r ddarlith ar Panopto drwy

Mae'r ddogfen fer hon gan Dr Hywel Griffiths yn cynnig cyflwyniad cryno i ddatblygu sgiliau trin a thrafod a chyflwyno data ystadegol o fewn Excel, ac yn addas ar gyfer myfyrwyr yn ystod tymor cyntaf eu hastudiaeth israddedig pan efallai y bydd gofyn iddynt ddefnyddio Excel am y tro cyntaf, cyn ei ddefnyddio er mwyn gwneud dadansoddiadau mwy manwl. Sgiliau TG sylfaenol yw ffocws y ddogfen felly, a'r gobaith yw y gall fod yn sail ar gyfer tasg fer mewn seminar neu diwtorial. Ar ddiwedd y ddogfen, nodir rhai cwestiynau a phwyntiau trafod y gellir ymhelaethu arnyn nhw yn y sesiynau hyn. Cliciwch ar 'Cyfryngau Cysylltiedig' i lawrlwytho'r data . Mae gallu trin data ystadegol yn sgil greiddiol o fewn y gwyddorau amgylcheddol, boed hynny ym maes daearyddiaeth ffisegol, daearyddiaeth dynol neu wyddor amgylcheddol. Defnyddir ystod o ddulliau casglu, cyflwyno a dadansoddi data ystadegol mewn ymchwil academaidd a gan gyrff ac asiantaethau sydd yn rheoli'r amgylchedd yng Nghymru. Mae sawl meddalwedd ar gael er mwyn trin a thrafod data, ac mae rhai yn fwy defnyddiol ar gyfer gwahanol bwrpasau (arddangos, dadansoddi ac ati). Un o'r rhai mwyaf cyffredin yw MS Excel.  

In this article, we determine and analyse possible solutions to the problem of partitioning a circular cylinder into three regions of equal volume using the least surface area. The solutions are related to the minimal energy arrangement of films in dry aqueous foam confined in a cylinder. We enumerate the possible solutions and use the numerical simulation software Surface Evolver to calculate the area in each case. We determine the least area configuration for all values of the aspect ratio of the cylinder. We find only four possible optimal solutions, each appropriate over different intervals of the aspect ratio, and give closed form expressions for each one.

With the publication of its Welsh-medium Education Strategy in April 2010, the Welsh Assembly Government recognised the leading role of Welsh-medium education in the field of bilingual education throughout Europe and the world during the last fifty years. As the system further develops with increasing numbers of pupils choosing bilingual education in Wales, it is emphasised that it is important to be aware of the patterns and models available in other bilingual communities that successfully integrate bilingualism or multilingualism into their provision so that we can understand their relevance to our particular situation in Wales. This article gives an overview of the most recent developments in bilingual education in an international context and considers the important issues that emerge as this type of education continues to develop to cater for the needs of pupils in bilingual and multilingual communities throughout the world in the twenty-first century.

This article outlines the valuable contribution made by Annie Ellis (neé Davies) to the folksong revival in Wales and in particular her influence in the Aberystwyth/Cardiganshire district during the early decades of the Twentieth Century. It draws on original correspondence, fieldwork diaries, notated transcriptions, newspaper articles (in Welsh and French) and phonograph recordings from the National Library of Wales, the British Library, Bibliotèque Nationale de France and private collections. The following areas are discussed: Annie Ellis’s involvement in folksong related activities at the University of Wales, Aberystwyth, including the establishing of the Canorion Society, folksong collecting competitions and performances of J. Lloyd Williams’s operetta, Aelwyd Angharad (Angharad’s Hearth). Six historically significant concerts of traditional Welsh music given by a quartet of undergraduate singers in Paris during March 1911, including performances at Le Lied en Tout Pays and the Richelieu Amphitheatre (Sorbonne). This visit represented the embodiment of the Entente Cordiale established between Britain and France during the years leading up to the First World War. Association with Madame Lucie Barbier (head of vocal studies at the University) and the positive response of the Parisian press. Ruth Lewis and Annie Ellis’s three day fieldwork visit to Landyssul, Pencader and the surrounding district in June 1913 and the outcome of their folk song collecting, including an evaluation of the texts and melodies collected. The article also highlights the role of one Edwardian woman in developing the cultural life of Wales and her attempts to promote Welsh traditional music on an international platform.

Guidance: Using E-Badges as a method of recognising and rewarding Welsh language skills development. This guidance document was prepared by Pembrokeshire College and gives an insight into how they developed a badge award scheme to recognize the progression and development of learners' Welsh language skills. If you are interested in replicating this scheme at your college, an electronic copy of the resources (Moodle compatible) is available on request filling in the form below. 

The aim of this app is to support learners and workers in the Public Services sector to use the Welsh language with the public.  The vocabulary used within the app is compatible with the vocabulary that is included within the Pearson BTEC Level 3 Extended Diploma in Public Services specification. The app intoduces Welsh vocabulary and terms and contains audio clips to help users with pronunciation, along with interactive quizzes to test users' new knowledge.
