The biosorption of three reactive azo dyes (red, black and orange II) found in textile effluents by inactive mycelium of Cunninghamella elegans has been investigated. It was found that after 120 hours of contact the adsorption led to 70%, 85%, 93% and 88% removal of reactive orange II, reactive black, reactive red and a mixture of them, respectively. The mycelium surface was found to be selecti...

This study underlines the development of orange-colored spectrum tracer material based on Fe/CaCO3/PVC compound. The optimum composition compound was determined by comparing three different ratios Fe-CaCO3-PVC. sample with highest CaCO3 content decomposed earlier than that other samples. also produced lowest calorific energy around 275.61 cal/g and emitted a medium-dark orange spectrum. color b...

with Acridine Orange By DAvID M. JOHNSON, PEYTON T. PIiArr AND PEnnY G. RuGBY I HE IMPORTANCE OF lymphocytic RNA in immune function has received widespread attention in recent years.’ A case in point is the work of Mannick and Egdahl showing that adoptive immunity can be transferred from one animal to another by means of lymphocytic RNA.2 The RNA of the lymphocyte can be evaluated and compared ...

that achieved by TLC with numerous buffers (1,2,5) or by HV-TLE protocols (2) when multiple samples are analyzed. We have found that when 1 μL of a dye solution (1% orange G, 1% phenol red in pH 3.5 buffer) was electrophoresed in parallel with the phosphoamino acid standards, orange G migrated slightly ahead of pSer and phenol red migrated with pTyr, providing useful visible markers for electro...

Acaudina rosettis is one of the commercial sea cucumber species that widely consumed on east coast Surabaya, East Java, Indonesia. Although its abundance in nature has begun to show signs decreasing, studies this are still very limited. This study aimed examine indicators can be used determine sex A. individuals. samples were collected from Madura strait mid Hijri month for three months. The th...

OBJECTIVE In this study, we compared the antimicrobial activity of identical toothpastes differing only in silver or gold nanoparticles against the activity of one of the common toothpastes containing a chemical active ingredient. We also compared the active concentrations of the toothpastes. METHODS For this study, we selected "Royal Denta" toothpastes containing silver and gold particles, a...

Levels of polychlorinated dioxins/furans (PCDD/PCDF) in selected environmental samples (soils, sediments, fish, and farm animals) were analyzed from the area of Phong My commune (Thua Thien-Hue province, Vietnam). This area was affected by Agent Orange spraying during the Vietnam war (1968-1971). Whereas PCDD/PCDF content in soil and sediment samples is relatively low and ranges between 0.05 an...

Dark green leafy vegetables (DGLVs) are considered as important sources of iron and vitamin A. However, iron concentration may not indicate bioaccessibility. The objectives of this study were to compare the nutrient content and iron bioaccessibility of five sweet potato cultivars, including three orange-fleshed types, with other commonly consumed DGLVs in Ghana: cocoyam, corchorus, baobab, kena...

The effect of light conditions on the growth of green algae Chlorella vulgaris and cyanobacteria Gloeothece membranacea was investigated by filtering different wavelengths of visible light and comparing against a model daylight source as a control. Luminescent acrylic sheets containing violet, green, orange or red dyes illuminated by a solar simulator produced the desired wavelengths of light f...

Orange (Citrus sinensis) and grapefruit (Citrus paradise) peels were used as a source of pectin, which was extracted under different conditions. The peels are used under two states: fresh and residual (after essential oil extraction). Organic acid (citric acid) and mineral acid (sulfuric acid) were used in the pectin extraction. The aim of this study is the evaluation the effect of extraction c...
