Various extracts of Sarcostemma viminale were screened for central analgesic activity by hot plate test, peripheral analgesic activity by acetic acid-induced writhings, CNS depressant activity by pentobarbitone-induced sleep and locomotor activity testing methods and anthelmintic activity on the earthworms Pheretima posthuma . Results showed that petroleum ether and ethyl acetate extracts h...

The ethanol extract of the flowering top of Rosa damascena (Rosaceae) was assessed for neuropharmacological activities in mice using a number of experimental models. It significantly prolonged the pentobarbitone-induced sleeping time in mice, and showed mild to moderate central nervous system depressant activity when assessed by the hole cross and the open field tests in mice model when given...

The majority artificial lift used in MPA Field use PCTGL (Permanent coil tubing gas lift). is installed on several monobore well or dual well. Some wells the have waxy HPPO oil character with pour point between 85-100oF API 30-35. "MM-1" has a 95oF. high Pour of will be problem to solved. MM-1 produced PCTGL. From simulation, design was obtained at depth 2250 ft. With oil, depressant injection ...

For the past 5 years, Montana Tech has coordinated eff orts with Chevron Phillips Chemical to determine how organic depressant, disodium carboxymethyl trithiocarbonate (Orfom® D8 depressant), works separate chalcopyrite from molybdenite during cleaner flotation of a bulk sulfide concentrate. Pure minerals were studied by cyclic voltammetry, X-ray photoelectron spectroscopy, Fourier transform in...

Penggunaan pengurangan kertas merupakan salah satu upaya dalam mengimplementasikan kebijakan green campus. Pada proses pembuatan baja, terdapat fenomena slag foam, namun diperlukan depressant untuk mengurangi jumlah foam. Slag terbuat dari bahan organik, satunya adalah kertas. Oleh karena itu, limbah dimanfaatkan membuat depressant. foam pada basic oxygen furnace gelembung busa atau gas yang te...

In this paper, the potential of sulfonated naphthalene formaldehyde (SNF) condensate as a depressant in flotation separation scheelite from calcite was verified and investigated. The results microflotation experiments showed that SNF had stronger performance on than conventional depressant—water glass an excellent fine-grained particles (−0.037 mm) treatment. Adsorption tests were conducted to ...

This paper is one of a study that implements reverse flotation methods as an alternative beneficiation on bauxite processing. aimed at decrease silica content and increase alumina in so its qualified feed Bayer Process. The experiments were carried out 1375 mL cell tank. Dodecylamine (DDA) AERO 3000C used the collector, starch depressant, Dowfroth 1012 frother. overall conducted solid to soluti...

Background: Synedrella nodiflora (L) Gaertn. belonging to the family Asteraceae contains steroids, reducing sugars, phenolic, flavonoids, saponins, tannins and triterpenoids. Therefore, this study is designed to investigate its antioxidant, analgesic and CNS depressant effects. Materials and Methods: The antioxidant activity of methanolic extract of S. nodiflora (SN) was determined using Folin ...
