...DU. Mae’r dull hwn yn awgrymu bod iechyd meddwl gwael sy’n cael ei achosi gan amodau cymdeithasol yn cael ei ystyried yn hawdd ei drin drwy roi meddyginiaeth. Ond, mae’r bobl y gallai gwrth-iselyddion eu helpu yn ceisio eu hosgoi oherwydd y stigma cymdeithasol sy’n gysylltiedig â salwch meddwl, ac mae’r stigma hwnnw’n arwain at wahaniaethu ac allgáu. Yn yr...

Nodweddir symptomau PD gan gryndod, stiffrwydd cyhyrau ac anhyblygrwydd, blinder symud, a chydbwysedd a tharfu ar osgo, ynghyd â nam gwybyddol. Nod triniaethau sy'n seiliedig ar gyffuriau yw cynyddu faint o dopamin sydd yn yr ymennydd i leihau symptomau symud. Er eu bod yn effeithiol i lawer o bobl â PD, mae defnydd...

Minerals and the crystalline state

...composition (e.g. SiO2) is cooled very rapidly it will produce a silica glass, whereas if it is cooled slowly it will produce a crystalline solid composed of quartz crystals. It is important to note that compared with crystalline solids, glass is not a particularly stable form of matter. Over many years, glass may slowly convert into a crystalline form in a process called...

Night sky puts on a meteor shower to celebrate Rosetta’s closest approach to the sun

...composition. Orange is from sodium, the same colour that stains the night sky in cities, with reflected light from street lights. On most nights of the year, around six meteors per hour can be seen, assuming the skies are clear. These sporadic meteors emanate from random bits of dust from asteroids or comets. At certain times of the year, though, the count goes up to more...

...composition and material thickness, component complexity, and type and power of laser. Typical values for steel are 0.3 m min-1, 2 kW laser, 5 mm thickness and 2.7 m min-1, 5 kW laser, 3 mm thickness. Accurate control of welding speed is essential to control joint penetration, which depends on type and power of laser, and material. [Images to demonstrate 'Laser beam...
