Koninkryksteologie of verbondsteologie?

Kingdom Theology and Covenant TheologyOne of the tasks of Systematic Theology is to relate different aspects of the Christian Faith. This is often done by using a key concept. Well-known in Reformed Theology are the concepts Kingdom of God and Covenant. To put a theology developed along one key concept over against other theologies, is a rather apologetic and unfruitful approach. To relate such theologies meaningfully to each other, is an ecumenical, daring and rewarding approach. Both a Kingdom Theology and a Covenant Theology can be enriched by such an exercise. A Kingdom Theology tends to become impersonal and hard, while a Covenant approach may foster familiarity. Mutual exposure may prevent such extremes

Harga, Pembentukan Harga dan Keseimbangan Pasar

Seperti yang kita ketahui bahwa ekonomi takkan pernah lepas dari kata menjual, membeli, harga, dan mendapatkan keuntungan. Pasar adalah tempat bertemunya penjual dan pembeli yang sudah sepakat dengan harga yang ditawarkan. Harga adalah bentuk atau nilai sejumlah uang yang harus dibayarkan oleh seorang pembeli atau konsumen atas barang atau jasa yang sudah ia dapatkan dari penjual atau produsen. Harga pasar adalah tinggi rendahnya harga suatu barang yang terjadi atas kesepakatan produsen dengan konsumen. Sebelum terjadinya harga pasar, dimulai proses penetapan harga pasar. Yang ikut andil dalam penetapan harga pasar adalah para pelaku ekonomi, baik produsen maupun konsumen. Seorang produsen akan bisa menetapkan suatu harga barang berdasarkan dari beberapa hal termasuk biaya-biaya yang dikeluarkan dalam memproduksi suatu barang, selain dari jumlah permintaan barang dari konsumen, keuntungan yang ingin diperoleh, juga daya saing yang bisa saja terjadi anatar sesame produsen barang yang sama. Demi kestabilan harga, produsen akan melakukan hal-hal seperti menyediakan potongan harga atau diskon, atau melakukan promosi sehingga permintaan barang dari konsumen akan tetap dia peroleh dan permintaan barang juga bisa meningkat

Recent advances in the catalytic asymmetric 1,3-dipolar cycloaddition of azomethine ylides

Catalytic asymmetric 1,3-dipolar cycloadditions of azomethine ylides have turned out to be one of the most efficient methods for the preparation of enantioenriched pyrrolidines. The past decade has witnessed the development of a bunch of well-defined catalytic systems capable of affording excellent diastereo and enantioselectivities. Recently, a great effort has been focused on expanding the scope of the cycloaddition with regard to both reaction partners. In this review, we will discuss important advances that have been reported in this area since 2011The Ministerio de Economía y Competitividad (MINECO, project CTQ2012-3579) and Consejería de Educación de la Comunidad de Madrid (programme AVANCAT; S2009/PPQ-1634

Fungal biotechnology

Fungi are used in many industrial processes, such as the production of enzymes, vitamins, polysaccharides, polyhydric alcohols, pigments, lipids, and glycolipids. Some of these products are produced commercially while others are potentially valuable in biotechnology. Fungal secondary metabolites are extremely important to our health and nutrition and have tremendous economic impact. In addition to the multiple reaction sequences of fermentations, fungi are extremely useful in carrying out biotransformation processes. These are becoming essential to the fine-chemical industry in the production of single-isomer intermediates. Recombinant DNA technology, which includes yeasts and other fungi as hosts, has markedly increased markets for microbial enzymes. Molecular manipulations have been added to mutational techniques as a means of increasing titers and yields of microbial processes and in the discovery of new drugs. Today, fungal biology is a major participant in global industry. Moreover, the best is yet to come as genomes of additional species are sequenced at some level (cDNA, complete genomes, expressed sequence tags) and gene and protein arrays become available

Hydroamination reactions by metal triflates: Bronsted acid vs. metal catalysis?

Catalytic hydroamination reactions involving the addition of carboxamides (X = CO), carbamates (X = CO2) and sulfonamides (X = SO2) to unactivated CC bonds are briefly reviewed. Development in this field of catalytic research is briefly charted, followed by a discussion of possible mechanisms, including arguments to support the operation of both metal and Brønsted acid catalysis in these systems. Future developments in the area are summarised. © The Royal Society of Chemistry 2010.39511711175Müller, T.E., Hultzsch, K.C., Yus, M., Foubelo, F., Tada, M., (2008) Chem.

Metal-free solvent promoted oxidation of benzylic secondary amines to nitrones with H202

An environmentally benign protocol for the generation of nitrones from benzylic secondary amines via catalyst-free oxidation of secondary amines using H2O2 in MeOH or CH3CN is described. This methodology provides a selective access to a variety of C-aryl nitrones in yields of 60 to 93%.

Catalytic asymmetric synthesis of diazabicyclo[3.1.0]hexanes by 1,3-dipolar cycloaddition of azomethine ylides with azirines

Substituted 1,3-diazabicyclo[3.1.0]hexanes with two contiguous quaternary stereocentres are readily prepared by catalytic asymmetric [3+2] cycloaddition of α-substituted iminoesters with azirines. High diastereoselectivities and enantioselectivities (up to 98% ee) are achieved using CuI/(R)-Fesulphos as the catalytic systemWe thank the Spanish Ministerio de Economía, Industria y Competitividad (Grant CTQ2015-66954-P, MINECO/FEDER, UE) and FEDER/Ministerio de Ciencia, Innovación y Universidades – Agencia Estatal de Investigación (Grant PGC2018-098660-B-I00) for financial suppor

Gestión integral en la búsqueda de personas perdidas

[Resumen] La desaparición de personas es un hecho lamentable, que sucede a nivel mundial, si bien, no todas las casuísticas presentan la misma probabilidad en los diferentes países y lugares. En particular, en España, para abordar este problema se cuenta con el Sistema de Información de Personas Desaparecidas y Restos Humanos sin Identificar, responsabilidad del Centro Nacional de Desaparecidos. En este estudio, se analizan los datos estadísticos provenientes de distintas fuentes y, finalmente se propone un Protocolo de Actuación de búsqueda de personas desaparecidas de forma involuntaria (perdidas) particularizado para Ferrol.[Abstract] The disappearance of persons is an unfortunate fact that occurrs worldwide, although not all cases are equally likely to occurs in different countries and places. In particular, in Spain, the Information System of Missing Persons and Unidentified Human Remains, under the responsibility of the National Centre for Missing Persons, addresses this problem. In this study, statistical data from different sources are analyzed and, finally, an Action Protocol for the search of involuntary missing persons (missing persons) is proposed for Ferrol.[Resumo] A desaparición de persoas é un feito lamentable, que ocorre a nivel mundial, aínda que non en todos os casos presenta a mesma probabilidade nos distintos países e lugares.
