Quark (dairy product) then known as "syrniki". In Latvia, quark is eaten savory mixed with sour cream and scallions on rye bread or with potatoes. In desserts, quark is commonly baked into "biezpiena plātsmaize", a crusted sheet cake baked with or without raisins. A sweetened treat "biezpiena sieriņš" (small curd cheese) is made of small sweetened blocks of quark dipped in chocolate. Estonian Quark is evaluated on olfaction, vision, taste, after taste, and texture and is distributed nationally as well as to nearby regions. Although common in continental Europe, manufacturing of quark is rare in the Americas. A few dairies manufacture it, such
Quark-nova of the projected neutron star population. A conservative estimate based on this, indicates that up to two quark-novae may occur in the observable universe each day. Theoretically, quark stars would be radio-quiet, so radio-quiet neutron stars may be quark stars. Direct evidence for quark-novae is scant; however, recent observations of supernovae SN 2006gy, SN 2005gj and SN 2005ap may point to their existence. Quark-nova A quark-nova is the hypothetical violent explosion resulting from the conversion of a neutron star to a quark star. Analogous to a supernova heralding the birth of a neutron star, a quark nova signals the creation
