Methods: One commodity future from each group of futures is chosen for the analysis. The select commodities are potato, gold, crude oil, and mentha oil. The data are collected from MCX India over the period 2004–2012. This study uses several econometric techniques for the analysis. The GARCH model is introduced for examining the volatility of commodity futures. One of the key contributions of t...

Almost from the inception of Hilbert’s program, foundational and structural efforts in proof theory have been directed towards the goal of clarifying the computational content of modern mathematical methods. This essay surveys various methods of extracting computational information from proofs in classical first-order arithmetic, and reflects on some of the relationships between them. Variants ...

Analyses of 71 Roman provincial silver coins of the Julio-Claudian emperors (27 BC–AD 68) minted at Caesarea in Cappadocia and Antioch and Tyre in Syria are discussed in this paper. The finenesses of the alloys are presented and it is proposed that there was a logical relationship between the standards used for Caesarea and Antioch. Trace element profiles and selected lead isotope analyses help...

This research evaluated the effects of biosolid levels on yield and chemical composition of Mentha piperita L. essential oil. Mint plants were grown in a greenhouse in pots containing the equivalent to 0, 28, 56, and 112 t.ha-1 biosolid. Three evaluations were made at 90, 110, and 120 days after planting (DAP). The oil was extracted from the dry matter of shoots by hydrodistillation, and compos...

trichomoniasis is one of the most common urinary-genital tract disease. the causal agent of trichomoniasis is flagellate protozoan called trichomonas vaginalis. metronidazole and tinidazole are the drug of choice for treatment. carcinogenic and embryo-teratogenic effects of the mentioned drugs and resistance to metronidazole has been reported. according to cytotoxic effects of medicinal herbs i...

The insecticidal effects of 20 essential oils derived from herbs, were tested against the housefly species Musca domestica L. using a susceptibility test. Each was applied in ethyl alcohol at concentrations of 1, 5 and 10% (v/v). Ten percent concentrations of Cymbopogon citratus (lemongrass), Mentha piperita (peppermint) and Lavandula angustifolia (lavender) oils were the most effective, showin...

Six essential oils: asteraceae oil, rutaceae oil, mentha piperta oil, carvacryl oil, citronella oil, and eucalyptus oil were tested for evaluation of their repellent effects against Aedes albopictus mosquitoes under laboratory conditions. Only citronella oil and eucalyptus oil were tested with human beings. There was considerable protection for mice. Carvacryl oil (7%) provided 100% protection ...

* Author for correspondence and reprint requests Z. Naturforsch. 64c, 809-812 (2009); received May 7/July 23, 2009 Menthalactone, a new long-chain alkene with a bicyclic lactone moiety, was isolated as an analgesic constituent from the leaves of Mentha cordifolia Opiz. At a dosage of 100 mg/ kg mouse, it decreased the number of squirms induced by acetic acid by 67.3%. Statistical analysis using...

Interactions between herbivorous insects and plants storing terpenoids are poorly understood. This study describes the ability of Chrysolina herbacea to use volatiles emitted by undamaged Mentha aquatica plants as attractants and the plant's response to herbivory, which involves the production of deterrent molecules. Emitted plant volatiles were analyzed by GC-MS. The insect's response to plant...
