Soil organic carbon (SOC) sequestration in arable soils is a challenging goal. We focused on the effect of crop rotation and previous land use for future two experimental fields Retisols with four contrasting fertilization treatments each. analyzed SOC dynamics used RothC model to forecast SOC. found consistent increase stocks stable fractions soil matter (SOM) C accumulation next 70 years comp...

Erat hubungan antara iklim dan tanaman kopi membutuhkan langkah yang tepat dalam perencanaan pengembangan kopi. Sulawesi Selatan merupakan salah satu wilayah penghasil arabika sedang direncanakan pengembangannya. Penelitian ini bertujuan mengetahui sebaran kesesuaian Arabika di masa depan berdasarkan hasil proyeksi skenario RCP8.5 periode tahun 2021- 2050 2051-2080 Selatan, digunakan sebagai re...

It is known that the only finite topological spaces that are Hspaces are the discrete spaces. For a finite poset which is weakly equivalent to an H-space, a generalized multiplication may be found after suitable subdivision. In this paper we construct minimal models of the k-fold generalised multiplications of circles in the category of relational structures, including poset models. In particul...

Abstract Coffee cultivation in Central America provides goods and services at local, national, international levels. Climate change is likely to affect the magnitude continuity of these benefits by reducing land suitability for coffee cultivation. To quantify impacts climate on suitability, we use Bayesian network model Agroecological Land Evaluation Coffea arabica L. (ALECA) estimate productio...

Climate change affects building cooling demand; however, little has been done to explore this effect and show its variability in different climatic zones. This review organizes summarizes studies which have simulated the impact of climate on requirements, critically analyzes effectiveness mitigation strategies proposed by these alleviate impact. The methodology selected that reported demand dis...

5. Specimens from Prof. C. J. Watson's laboratory have been examined. The uroporphyrin methyl ester I had m.p. 292-293° and behaved as uroporphyrin I containing a trace of uroporphyrin III on paper chromatography. The 2080 ester behaved chromatographically as a hexacarboxylic porphyrin. We wish to thank Dr Falk and Miss Benson for performing the chromatographic examinations by their method, and...
