Pancasila merupakan dasar negara dan juga pandangan hidup bangsa Indonesia yang terdapat nilai-nilai luhur mencerminkan kehidupan masyarakat Indonesia, sebab pada dasarnya tersebut digali dari jiwa kepribadian sejak zaman dahulu. Tujuan penelitian adalah untuk memahami konsep etika politik itu sendiri, serta agar paham dalam di Indonesia. Dalam ini, menjadi subjek literatur terkait dengan Panca...
In membranes of the rat frontal cortex, acetylcholine (ACh) and other cholinergic agonists were found to potentiate the stimulation of adenylyl cyclase activity elicited by corticotropin-releasing hormone (CRH). Oxotremorine-M, carbachol and methacholine were as effective as ACh, whereas oxotremorine and arecoline were much less effective. The facilitating effect of Ach was potently blocked by ...
The musearlnie receptors are currently divided into at least three subtypes: M1, M 2a and M 2ß (for recent reviews, see Eglen and Whiting, 1986; Mutschier et al., 1987; 1988). M1-Receptors are found in high density in neuronal tissues such as autonomic ganglia, cerebral cortex and hippocampus, whereas M 2-receptors are mainly present in lower brain areas and in peripheral effector organs such a...
The Streptococcus Invasion Locus (Sil) was first described in Streptococcus pyogenes and Streptococcus pneumoniae, where it has been implicated in virulence. The two-component peptide signaling system consists of the SilA response regulator and SilB histidine kinase along with the SilCR signaling peptide and SilD/E export/processing proteins. The presence of an associated bacteriocin region sug...

Two transferable physical parameters are incorporated into the Su-Schrieffer-Heeger Hamiltonian to model conducting polymers beyond polyacetylene: the parameter γ scales the electron-phonon coupling strength in aromatic rings and the other parameter ε specifies the heterogeneous core charges. This generic Hamiltonian predicts the fundamental band gaps of polythiophene, polypyrrole, polyfuran, p...
Novel poly(arylene ethynylene)s comprising a cinnoline core were prepared in high yields via a three-step methodology. A Richter-type cyclization of 2-ethynyl- and 2-(buta-1,3-diynyl)aryltriazenes was used for cinnoline ring formation, followed by a Sonogashira coupling for the introduction of trimethylsilylethynyl moieties and a sila-Sonogashira coupling as the polycondensation technique. The ...
Stereoselective synthesis of vinylsilanes by a gold(I)-catalyzed acetylenic sila-cope rearrangement.
Cationic tri-tert-butylphosphinegold(I) serves as a catalyst in the sila-Cope rearrangement of acetylenic allylsilanes. When phenol is employed as a nucleophile, the reaction allows for the stereoselective synthesis of vinylsilanes. Alternatively, use of methanol as a nucleophile leads to cyclic vinylsilanes, which can be viewed as latent vinylsilanes that are revealed on treatment with a mild ...
Demokrasi pancasila adalah demokrasi yang dihayati oleh bangsa dan Negara Indonesia dijiwai diintegrasikan sila-sila Pancasila atau nilai-nilai luhur Pancasila. Secara luas berarti kedaulatan rakyat berdasarkan pada bidang politik, ekonomi, sosial.
