This paper develops an elementary theory of global supply chains. We consider a world economy with an arbitrary number of countries, one factor of production, a continuum of intermediate goods, and one –nal good. Production of the –nal good is sequential and subject to mistakes.

This article briefly outlines Blomstrand's life and considers his best known book, Die Chemie der Jetztzeit (1869), as well as his work on mineralogy, inorganic chemistry (the earth acid elements, heteropoly acids, platinum complexes), and his theoretical views on valency, diazo compounds, and metal-ammines. His so-called ‘chain theory’, as developed and modified by his fellow Scandinavian chemist and close friend, Sophus Mads Jørgensen, was for more than three decades the most popular

Drawing structures analogous to organic chemicals, they arrived at a cobalt metal bound to long chains of ammonia, with a chlorine at the end of each group. Question: 2.8 In The Same Way That The Ammonia Molecule Was Thought To Have An Overall Valence Of 2 And Was Represented As-NH3- In The Blomstrand-Jørgensen Chain Theory, Water Can Be Represented As -H2O-. TEORI RANTAI BLOMSTRAND-JORGENSEN. 1869 Blomstrand (Swedia) mengajukan teori rantai untuk struktur kompleks logam. Karena tiap-tiap unsur mempunyai valensi yang tetap, maka Blomstrand dan Jorgensen mengatakan bahwa : Dalam kompleks kobal (III) hanya ada tiga ikatan.

Although he interpreted their structure in terms of the now defunct Blomstrand-Jørgensen chain theory, his pioneering experimental research on new series of platinum and rhodium compounds (as well as those of cobalt and chromium) has provided us with some of the most fundamental data of inorganic chemistry that are still valid today.

Blomstrand–Jorgensen chain theory Blomstrand in 1869 proposed the chain theory to explain the existence of metal complexes. Blomstrand and his student Jörgensen suggested there could be only three bonds to cobalt (III) in its complexes 5. 6.

Academic literature review discloses an important spurt in research in practice and theory of Supply Chain (SC) and Supply Chain Management (SCM).

While Jørgensen's theories on coordination chemistry were ultimately proven to be incorrect, his experimental work provided much of the basis for Werner's theories.

The coordination theory is an abrupt break with both the Kekulé valence theory and the Blomstrand- Jørgensen chain theory.It assumes that the metal is bound to 6 atoms or groups, creating a radical.

By the late 1860s Kekulé and others had shown that organic molecules were built up of chains and rings of quadrivalent carbon atoms, and in 1869 the Swedish chemist C. W. Blomstrand (1826–1897) suggested that metal-ammonia compounds contained chains of quinquevalent nitrogen atoms, with the −NH 3 − group playing a part similar to that of the −CH 2 − group in organic compounds ().

The coordination theory is an abrupt break with both the Kekulé valence theory and the Blomstrand- Jørgensen chain theory. It assumes that the metal is bound to 6 atoms or groups, creating a radical. The remaining atoms or groups are loosely bound to this radical.

To the compound CoCl 2 · 6NH 3 for example he gave the following constitu-tional formula: It was however known even in Blomstrand’s day that in certain of these ad-dition compounds of ammonia and metal salts, the individual acid residues Jorgensen was a real controversy. It is important to realize that not all controversies are of the same kind. They may usefully be distinguished in controversies of fact, of theory and of principle.4 In a controversy of fact, scientists disagree about the experimental basis of Inorganic Chemistry - Inorganic chemistry is the Branch of chemistry which deals with the compounds outside the realms of organic chemistry.

Physical fatigue is defined as the inability to maintain power output. The fatigue can be either central or peripheral in its origin. Several factors have been identified as a cause of peripheral fatigue (e.g., depletion of muscle glycogen or phosphocreatine, accumulation of protons, and failure of neuromuscular transmission), whereas the factors underlying central fatigue are less well known ().

The disappointment came when the Blomstrand-Jørgensen chain theory could not predict the conductivity or the number of ions that would exist in aqueous solution or rationalize the correct number of isomers of certain compounds.
