The Minang Bangkit Merbabu Farmer Group use organic materials and produce their own liquid fertilizer. This fertilizer is made of varied ingredients: rabbit urine, cow's milk, free-range chicken eggs, palm sugar, coconut water, pineapple, shrimp paste, bamboo roots, ginger, turmeric. Composting strongly affected by pH aeration method. Liquid farmers usually have an initial around 3.7. mixture w...

To investigate the role of placental transport of bile acids in fetal bile acid metabolism, such as with regard to synthesis of the unusual bile acids (1 beta- and 6 alpha-hydroxylated and unsaturated bile acids), we measured the concentrations of bile acids in umbilical cord blood, amniotic fluid, maternal serum and maternal urine at delivery by means of gas chromatography-mass spectrometry. S...

Sorption of organic molecules to mineral surfaces is an important control upon the aquatic carbon (C) cycle. Organo-mineral interactions are known to regulate the transport and burial of C within inland waters, yet the mechanisms that underlie these processes are poorly constrained. Streamwater contains a complex and dynamic mix of dissolved organic compounds that coexists with a range of organ...

This review will be concerned primarily with a practical yet comprehensive diagnostic procedure for the diagnosis or even mass screening of a variety of metabolic disorders. This rapid, highly sensitive procedure offers possibilities for clinical chemistry laboratories to extend their diagnostic capacity to new areas of metabolic disorders. The diagnostic procedure consists of the use of urine ...

fateme derakhshan-panah was born in hamedan (iran) in 1987. she received her b.s. in pure chemistry (2009) and m.s. in organic chemistry (2011) from bu-ali sina university, iran. she is currently working towards her ph.d. under the supervision of professor m. a. zolfigol. her research interest is organic methodology especially the application of solid acids and ionic liquids in organic synthesis.

background: determination of organic pollutants usually requires extraction of the pollutants from samples, using hazard­ous solvent. solid phase micro-extraction (spme) is a solvent-free equilibrium extraction method, in which, proper calibra­tion can allow quantitative measurements of organic pollutants at a very good sensitivity without the use of any organic sol­vent. because individual voc...

Certain organic carbon moieties in drinking source waters of the Sacramento-San Joaquin Delta can react with chlorine during disinfection to form potentially carcinogenic and mutagenic trihalomethanes. The properties of reactive organic carbon in Delta waters, particularly those of soil origin, have been poorly understood. This study attempts to characterize trihalomethane reactivity of soil or...

A main reason for the rapid increase in organic food consumption is the perception that organic foods have a superior nutritional composition and/or convey health benefits. However, there is currently limited scientific knowledge about the effect of production systems on food composition. The study reported here compared fatty acid profiles and levels of fat soluble antioxidants in milk from or...

Volatile fatty acids (VFA) are short chain aliphatic monocarboxylic acids containing from 2 to 8 carbon atoms in a molecule. They are formed in the process of anaerobic biodegradation of larger organic molecules and therefore are commonly present in municipal wastewater, effluents of food industry, livestock farm wastewater, sewage sludge, landfill leachate, feces, urine, etc. and are emitted b...
