Sustainable agriculture can increase the efficiency of resource utilization, provide longer productivity and create a balance in the environment. A field experiment was conducted to study the use of organic and chemical fertilizers on biomass, essential oil content and essential oil yield as well as chemical compositions of Dracocephalum polychaetum Burnm in the first and second cutting. The tr...

This study examines the role of enterprise information systems in fostering collaboration between the Purchasing, Production, and Outbound Logistics functions of manufacturing facilities. These forms of integrative information technology are considered key facilitators of supply chain management. The research model embeds these systems within a broader model of facilitators of interfunctional i...

agent, which has been on the market since 1984 in Japan for the prevention of rejection in renal transplantation. In contrast to other immunosuppressive agents (e.g., azathioprine), mizoribine has been shown in animal experiments to lack oncogenicity and has shown clinically a low incidence of severe adverse drug reactions (such as myelosuppression and hepatotoxicity), making it useful in long-...

A method for the analysis of several volatiles compounds responsible for orange juice flavour (ethyl butanoate, limonene, linalool, alpha-pinene, geranial, neral and alpha-terpineol) has been developed. The isolation of this compounds was carried out by pervaporation (PV) followed by on-line gas chromatography-mass spectrometry (GC-MS). The coupling PV-GC-MS has been successfully applied to fre...

in this study, aerial parts of lippia citriodora kunth were harvested at three phenological stages (i.e. vegetative, full flowering and fruit set). the essential oil isolated by hydro distillation for 3 h using a clevenger-type apparatus and the oil was analyzed by gc and gc-ms. the yields of oils (w/w%) in different stages was in the order of: full flowering (0.9%), vegetative (0.48%) and frui...

The volatile constituents of the aerial parts of vervain (Verbena officinalis L.) cultivated locally were investigated. Analysis of the volatile fraction by GC and GC-MS is described. Compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).
