Angst
Angst means fear or anxiety (anguish is its Latinate equivalent, and anxious, anxiety are of similar origin). The word angst was introduced into English from the Danish, Norwegian and Dutch word angst and the German word Angst. It is attested since the 19th century in English translations of the works of Kierkegaard and Freud. It is used in English to describe an intense feeling of apprehension, anxiety, or inner turmoil.
In German, the technical terminology of psychology and philosophy distinguishes between Angst and Furcht in that Furcht is a negative anticipation regarding a concrete threat, while Angst is a non-directional and unmotivated emotion. In common language, however, Angst is the normal word for "fear", while Furcht is an elevated synonym.
In other languages having the meaning of the Latin word pavor for "fear", the derived words differ in meaning, e.g. as in the French anxiété and peur. The word Angst has existed since the 8th century, from the Proto-Indo-European root *anghu-, "restraint" from which Old High German angust developed. It is pre-cognate with the Latin angustia, "tensity, tightness" and angor, "choking, clogging"; compare to the Ancient Greek ἄγχω (ankho) "strangle".
Lacrimosa (band)
HIDDEN ERROR: Usage of "Currently based in" is not recognized
Lacrimosa is a gothic duo led by German Tilo Wolff, the main composer, and Finn Anne Nurmi. They are currently based in Switzerland, but originally from Germany. Originally counted among the bands of the Neue Deutsche Todeskunst genre, Lacrimosa have developed their style more towards powerful metal, but Gothic elements still remain.
Their current musical style mixes gothic rock and heavy metal along with violin, trumpet and more classical instruments, although their musical development throughout the years has also led to changes in instrumentation. Lacrimosa's lyrics are written almost exclusively in German, although since the 1995 album Inferno every album has featured one or two songs in English, generally written by Anne Nurmi. Finnish has also appeared in the spoken intro to two songs ("Schakal" on Inferno and "The Turning Point" on Elodia) and on a bonus track in a limited edition release of Fassade called Vankina. Their lyrics are mainly about loneliness, sadness, darkness, despair and love.

R-value (insulation)
The R-value is a measure of thermal resistance used in the building and construction industry. Under uniform conditions it is the ratio of the temperature difference across an insulator and the heat flux (heat transfer per unit area per unit time, 
) through it or 
. Thermal resistance varies with temperature but it is common practice in construction to treat it as a constant value.
An R-value is a unit of thermal resistance for a particular material or assembly of materials (such as an insulation panel). The R-value depends on a solid material's resistance to conductive heat transfer. For loose or porous material, the R-value accounts for convective and radiative heat transfer through the material. However it does not account for the radiative or convective properties of the material's surface, which may be an important factor for some applications.
R is expressed as the thickness of the material normalized to the thermal conductivity. The unit thermal conductance of a material is the reciprocal of the unit thermal resistance. This can also be called the unit surface conductance. The higher the value of R, the better the building insulation's theoretical effectiveness.
