Araith gan David Lloyd George a draddodwyd ym Mangor yn 1915 pan oedd yn Ganghellor y Trysorlys er mwyn annog cefnogaeth i'r Rhyfel Byd Cyntaf. Mae'r e-lyfr hwn yn ffrwyth prosiect DEChE – Digido

Prif amcan yr e-lyfr hwn gan yr Athro Paul O'Leary yw archwilio'r modd y cafodd Cymru ei dehongli gan sylwebyddion a theithwyr Ffrangeg eu hiaith yn y bedwaredd ganrif ar bymtheg. Gwneir hyn trwy gyflwyno ffynonellau yn yr iaith wreiddiol gyda chyfieithiadau i'r Gymraeg o destunau nad ydynt, hyd yn hyn, wedi'u defnyddio gan haneswyr. Maent yn dangos yr amrywiaeth o drafodaethau am Gymru a gafwyd yn Ffrainc, yn bennaf yn yr hanner canrif rhwng tua 1830 a'r 1870au pan drawsnewidiwyd Cymru gan dwf yn y boblogaeth (yng ngwlad a thref) a diwydiannu prysur. Mae'r ffynonellau yn ymwneud â thair thema oedd yn ganolog i fywyd yr oes: y duedd ymhlith rhai carfannau o bobl i wrthryfela yn erbyn awdurdod mewn cyfnod o newidiadau cymdeithasol ac economaidd sylfaenol; yr ysfa i wybod am wreiddiau ac effeithiau twf diwydiant a masnach; a safle iaith ddiwladwriaeth a'i diwylliant mewn cyfnod pan oedd gwledydd Ewrop yn ymdrechu i greu cymunedau cenedlaethol uniaith ac unffurf.

Dyfyniadau o areithiau ac erthyglau gan E. T. John, Aelod Seneddol dwyrain Sir Ddinbych yn ystod y Rhyfel Byd Cyntaf, cenedlaetholwr Cymreig a heddychwr. Roedd yn aelod o'r Blaid Ryddfrydol hyd 1918, pan ymunodd â'r Blaid Lafur. Cyhoeddwyd gyntaf yn 1918.

Amcan yr adnodd hwn yw helpu actorion a sgriptwyr Cymraeg, nid yn unig i ymgyfarwyddo â gwahanol amrywiadau tafodieithol, ond hefyd i’w defnyddio yn ymarferol wrth eu gwaith bob dydd. Ceir yma glipiau sain wedi eu recordio’n Ionawr 2015 gan Dr Iwan Rees o dafodieithoedd yn Nyffryn Banw yn Sir Drefaldwyn.  Mae’r atodiadau’n cynnwys canllawiau manwl gan Dr Iwan Rees ar gyfer pob clip  gan dynnu sylw at elfennau ieithyddol penodol (ar eirfa, seiniau, gramadeg a’r oslef, er enghraifft). Oherwydd resymau hawlfraint, bydd angen mewngofnodi er mwyn cael mynediad i nifer o'r cilipau fideo.

Cyflwyniad i'r Rhyfel Canmlynedd (1337-1453) a'i berthynas â Chymru a geir yn y gyfrol hon . Roedd gan filwyr o Gymru rannau canolog yn y rhyfel hwn rhwng Lloegr a Ffrainc, a hynny ar y ddwy ochr. Ystyrir hefyd effeithiau'r Rhyfel Canmlynedd ar Gymru ei hun.

The Cluster spacecraft are used in order to investigate the solar wind, and because there are four spacecraft, it allows a measurement of the 3-D structure of the solar wind. Since turbulence is a 3-D phenomenon, Cluster is ideal for investigating turbulence. These observations show that the turbulence at proton gyration scales are dominated by Kinetic Alfvén waves as well as magnetic vortices. This research strengthens the hypothesis that Kinetic Alfvén waves are present in the solar wind and suggests for the first time that waves and magnetic vortices can coexist in the solar wind.

Emile Durkheim was the first to hold a university chair in sociology, and his ideas remain of fundamental importance to all who want to understand the origins of the subject. He adopted the image of society as an organism, each part of which has a particular role to play in ensuring the well-being of the whole body. His ideas include an analysis of the social origins of religion, in particular the suggestion that any religious worship is 'worship of society'; its emphasis on what he called 'anomie' as the root of dispute and unrest in the life of an individual and society; and his original and important study of suicide as a social phenomenon. His influence is seen in fields as diverse as criminology on the one hand and literary criticism on the other.

In recent years, considerable attention has been given to the experiences of minority groups which are marginalised within a rural context. However, little attention has been paid to religious minorities in rural regions. This scarcity of attention is surprising considering the attention paid to religion in issues of multiculturalism and inclusive citizenship. This paper discusses the experiences of one particular religious group, Muslims, in rural west Wales. The article concentrates on experiences of absence from the landscape (i.e. the physical landscape and the broader images and values that convey ideas about places), which can create difficulties in fostering a sense of community. It also looks at local Muslims’ construction of the landscape in moral and Christian terms. The paper suggests that these experiences transcend ideas of ‘exclusion/belonging’, and attest to a complex relationship between local Muslims and this rural region.

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.
