We present a density functional theory (DFT) calculation in the generalized gradient approximation to study the possibility for the existence of Jahn-Teller (JT) or pseudo Jahn-Teller (PJT) type local distortions in the La-Ba-Cu-O superconducting system. We performed the calculation and correspondingly group theory classification of the electronic ground state of the CuO6 elongated octahedra cl...

Dark matter pair-production in b → s transitions. The flavour-changing neutral current transition b → s can serve as a sensitive probe of WIMP dark matter models, if the WIMP mass is under 2 GeV. In this work we extend our earlier analysis to a generic class of models where the interaction between the dark matter sector and the Standard Model matter sector is mediated by the Higgs boson(s). We ...

Elevated plasma homocysteine level promotes atherosclerosis in blood vessels due to, among others, generation of reactive oxygen species and reduction of nitric oxide bioavailability. The aim of this study was to investigate whether melatonin administration reduces plasma homocysteine level in rats consuming increased doses of methionine in the diet. The trial lasted for two months. The rats we...

The catfish wastewater is directly discharged into the environment, it will disrupt lives of both humans and other organisms. This study aims to determine amount macronutrients nitrogen, phosphate, potassium from farming waste as liquid organic fertilizer (LOF) through fermentation process at different times, potential economic value, by determining cost production selling price products. Culti...

Turmeric is a medicinal plant that has many benefits. There are more turmeric production centers in Indonesia Java and Sumatra, it does not rule out the possibility of Aceh Province, one which Seulimum District. The limited knowledge possessed by farmers, both technology market, makes farmers prefer to sell directly their harvests rather than processing them first into other products. purpose t...
