Arabica coffee (Coffea arabica) is one of the most popular coffees among Acehnese, an ethnic group from Aceh, Indonesia. The amount consumed directly proportional to waste produced. Spent grounds are residue obtained during brewing process. can be utilized by converting them into active charcoal adsorbents. This study aimed produce activated spent arabica (SACG), utilize it as ingredient in liq...

Finally in the project work Atenolol is an anti-hypertensive drug. It has been formulated into fast dissolving tablets by direct compression method using Excipients like lactose, sucrose magnesium stearate, sodium lauryl and sulphate many type super disintegrates such as crosscarmellose starch glycolate prepared were evaluated for pre-compression parameter angle of repose, bulk density, tapped ...

Tests based on the polymerase chain reaction (PCR) for the detection of the Mycobacterium tuberculosis complex in clinical samples have a lower sensitivity when compared to culture. This has been attributed to the presence of inhibitors to Taq polymerase and/or suboptimal DNA extraction procedures. We tested different methods of processing smear negative culture positive sputum (n = 52) using d...

Fullerene (C(60)), the third carbon allotrope, is a classical engineered material with the potential application in biomedicine. However, extremely high hydrophobicity of fullerene hampers its direct biomedical evaluation and application. In this work, we investigated the solubilization of fullerene using 9 different solubility enhancers: Tween 20, Tween 60, Tween 80, Triton X-100, PVP, polyoxy...

For the investigation of the skin irritancy potential of chemicals in an in vitro model, it is necessary to have sensitive end-points that predict the effects on native human skin. Our aim was to investigate whether the induction of the proteinase inhibitor SKALP in reconstructed epidermis can be used as a marker. The influence of culture conditions and the effect of topical application of sodi...

Concentrated aqueous solutions of surfactants pastes are widely used in industrial productions. The dissolution phenomena these fluids water is difficult to optimize, given the thermodynamic complexity system, that adds further resistance mass transport efficiency. One most common anionic Sodium Lauryl Ether Sulphate (SLE 3 S). Depending on SLE S-water composition, surfactant nano-molecules can...

Five broth media and two solid media were compared for their ability to quantitatively recover total coliform bacteria from chemically treated water. M-Endo LES and mT7 media were used in the membrane filter technique. Lauryl tryptose broth, lactose broth, presence-absence broth, lactose broth with twice the amount of lactose, and lauryl tryptose broth with twice the amount of sodium lauryl sul...

Coalescence frequency and lifetimes of thin aqueous films formed between nitrogen bubbles were measured in dilute solutions of sodium lauryl suitate, «-amyl alcohol, and 1-butanol. The bubble pairs were formed on two adjacent capillary tubes by use of a microprocessor-controlled stepping motor, and the coalescence time was determined by an optical sensing method. For low-molecular weight alcoho...

The effect of 3 protective creams and petrolatum was tested in a repetitive irritation test. On 15 healthy volunteers, the irritants (sodium lauryl sulfate 10%, sodium hydroxide 0.5%, lactic acid 15%, and toluene undiluted) were applied on the paravertebral skin of the mid-back after 30 min pretreatment with the products tested. The volunteers were treated for 9 days. The irritant cutaneous rea...
