seacarbx - seacarb extension for deep-time carbonate system calculations
No full textseacarbx is a seacarb extension written in R, which enables to use seacarb (Gattuso et al., 2019) for deep-time carbonate system calculations or for culturing studies carried out in seawater with modified [Mg2+] and [Ca2+]. For this, the functions carb, K0, K1, K2, Ks, Kw, Kb, Kspa, and Kspc were modfied to account for the effect of seawater [Mg2+] and [Ca2+] on the dissociation constants of carbonic and boric acid. In addition to the modified functions, seacarbx contains MyAMI that are tabulated parameters defining the temperature and salinity dependencies of the conditional equilibrium constants for [Mg2+] and [Ca2+] in the range 1–60 mM (from Hain et al., 2015, 2018), as well as a function for bilinear interpolation.Funded by the Deutsche Forschungsgemeinschaft (DFG – German Research Foundation) through a research project (no. RA 2068/4-1) granted to Markus Raitzsch

Mg/Ca, B/Ca and U/Ca in shells of benthic foraminifers: Tracers of temperature and seawater carbonate chemistry
No full textMg/Ca ratios in benthic foraminiferal shells are frequently used in paleoceanographic studies to estimate past bottom water temperatures. Apart from temperature, other factors may exert additional influences on foraminiferal Mg/Ca. These include the Mg/Ca ratio of seawater, partial dissolution of shell calcite, salinity, physiological effects, and, probably of capital importance, the carbonate chemistry of seawater. In this context, the separate effects of temperature and seawater carbonate chemistry on the magnesium incorporation into benthic foraminiferal calcite are unraveled and quantified in this thesis. Further, B/Ca and U/Ca in benthic foraminifers were investigated as potential carbonate system proxies that may be used to correct for the carbonate ion effect on Mg/Ca

Strategi Pelayanan Lintas Budaya Berdasarkan Markus 4:1-34
No full textHarming & Katarina, Cross-cultural Service Strategy based on Mark 4: 1-34. The author conducted a study of the text of Mark 4: 1-34 using qualitative research literature study using the biblical hermeneutic principle. Based on the analysis of the text of Mark 4: 1-34 the authors find there are four cross-cultural service strategies namely by understanding local culture, using media. Harming & Katarina, Strategi Pelayanan Lintas budaya Berdasarkan Markus 4:1-34. Penulis melakukan penelitian terhadap teks Markus 4:1-34 dengan menggunakan penelitian kualitatif studi pustaka dengan menggunakan prinsip hermeneutik Alkitab. Berdasarkan analisis terhadap teks Markus 4:1-34 penulis menemukan ada empat strategi pelayanan lintas budaya yaitu dengan memahami budaya lokal, menggunakan media yang ada dalam budaya, memberdayakan potensi yang ada, dan menciptakan terobosan
