The Sun is a dynamic, complex system, full of interesting and important features. These kinds of features can be modeled in various ways, such as with Non-Linear Force-Free Field (NLFFF) models. In this paper, NLFFF simulations are built. The intention is to estimate spatial patterns of the magnetic field in the solar chromosphere and corona and changes in the free energy in the system, in particular losses of energy as a result of solar eruptions. Most existing models have a temporal cadence of 12 minutes at best (that is, the situation is simulated every 12 minutes). The method discussed in this paper makes various approximations but it aims to achieve a temporal cadence of 45 seconds. The method used is found to successfully simulate synthetic data, and when dealing with real data, it produces images which frequently correspond well to observations. Several reductions in the free energy of the system are seen, corresponding to observed eruptions.

This collection of essays by contemporary artists living and working in Wales gives potential Art and Design students an insight into how some of our artists discovered their creativity through education and effort during their careers. 

A series of short video clips featuring Welsh speakers working in occupations relevant to business modules in Higher and Further Education.  The individuals featured in the clips come from a variety of business backgrounds, including marketing, management and tourism. The clips are designed to be incorporated by lecturers in their lectures. They can also be used for recruitment purposes. For Further Education lecturers, the following videos are relevant to core units of Level 3 Business BTEC: Unit 1: Exploring Business – ‘Sefydlu Busnes' videos 4, 12, 13, 14, 15, 16, 17 Unit 2: Developing a Marketing Campaign - 'Marchnata' videos 1, 2 Unit 5: International Business -  'Cyllid' video 2 Unit 6: Principles of Management – ‘Adnoddau Dynol’ videos

A collection of resources suitible for lecturers and trainees to facilitate the teaching and learning of Welsh second language across the primary education sector. The range of language mats can be used as a basis for lectures, as a practical guide to using every day language, and as an aid to ensure accuracy when preparing worksheets, murals and writing modelling.  Cynllun Colegau Cymru no longer exists. It was replaced by the Language Competency Framework for Education Practitioners in 2018. This is the Framework that will has been adopted to measure the language skills of all trainees on Initial Teacher Education courses. The language tasks and activities in the material below are still relevant, but the specific references to the levels and steps of the Cynllun Colegau Cymru are not. 

These resources are learning packs with the aim of developing students' knowledge, based on realistic situations. The packs contribute to specific modules at the University of South Wales School of Nursing, but can also be used by students from other universities studying any branch of Nursing through the medium of Welsh. They could also be useful to others interested in the field.

Welsh translation of the Communist Party Manifesto (Manifest der Kommunistischen Partei). The original translation was published in 1948 to celebrate the centenary of the Manifesto. W. J. Rees based his translation on the fourth German edition (1890). A revised translation was published in 2008, which is the version available  here, along with the original introduction to the 1948 publication, the 2008 introduction by Robert Griffiths and a new preface to the digital publication by Howard Williams.

Historic coal mining and the associated processes have had a detrimental effect on the natural environment in the south Wales coalfield as contaminated mine drainage from abandoned mines discharges into the local hydrological system. The legacy of coal mining includes the discharge of contaminated mine drainage from several abandoned mines and the formation of insoluble iron minerals. This article discusses the underground processes that lead to the formation of contaminated water and iron minerals. Four abandoned coal mines located in the western part of the coal field and the remediation systems operational at these sites were investigated. Contaminated mine waters at these sites are being remediated through the removal of iron so that the final concentrations are in line with those recommended by the Water Framework Directive.

Dyma gasgliad o deuddeg o ysgrifau ar wahanol agweddau ar ffilm a'r cyfryngau. Mae rhai wedi eu lleoli'n ddiamwys ym myd y diwydiannau Cymreig a Chymraeg, ac eraill yn drafodaethau a fyddai'n nodweddu astudiaethau o'r fath mewn sawl rhan o'r byd. Prif bwrpas y gyfrol yw darparu deunydd addas ar gyfer myfyrwyr sydd yn dilyn modiwlau a graddau yn y meysydd hyn drwy gyfrwng y Gymraeg, ac fe ddatblygwyd y gyfrol gan ddarlithwyr o nifer o brifysgolion Cymru. Cefnogwyd y gyfrol gan y Coleg Cymraeg Cenedlaethol, a dyma un o gyhoeddiadau cyntaf y sefydliad hwnnw.Mae'r gyfrol electronig hon yn manteisio ar dechnoleg sydd yn ychwanegol at yr hyn a geir mewn cyfrol brint: mae yma hyperddolenni sydd yn arwain y darllenydd at dudalen derminoleg wrth glicio ar rai geiriau all fod yn anghyfarwydd yn y testun. Gobeithio y bydd hyn yn hwyluso'r darllen ac yn cyfrannu at ddatblygu, ehangu a sefydlogi terminoleg yn y meysydd hyn.Er nad all un gyfrol ddarparu deunydd cyflawn i gyrsiau prifysgolion mewn unrhyw bwnc, gobeithir y bydd y casgliad hwn yn cyfrannu at ddysg ac yn ysgogi rhagor o astudio, ymchwilio a chyhoeddi ym meysydd astudiaethau ffilm a'r cyfryngau drwy gyfrwng y ..
