The performance of an anaerobic baffled reactor (ABR) was evaluated in the treatment of cassava wastewater, a pollutant residue. An ABR divided in four equal volume compartments (total volume 4L) and operated at 35ºC was used in cassava wastewater treatment. Feed tank chemical oxygen demand (COD) was varied from 2000 to 7000 mg L(-1) and it was evaluated the most appropriated hydraulic retentio...

Aegle marmelos Linn is a common plant used to treat many disease Conditions in Indian traditional systems of medicine. The present study was undertaken to findout a scientific validation for the efficacy of Aegle marmelos against gastric ulcer. Aqueous extract of Aegle marmelos leaves was prepared and used for investigation. A daily does of 1 gm/kg body weight of the extract administered orally...

The sensitivity of the cortex to variations of its pH within the physiological range is striking.' It is highly probable that the activity of other organs is similarly affected by their acidity. The intimate relation of the blood and its capacity to condition these reacting systems is obvious. However, very little is known of the actual moment-to-moment fluctuations of the hydrogen concentratio...

A study was conducted to determine the effects of packaging materials, seasonality, storage temperature and time on physiochemical and antioxidant properties of roselle-mango juice blends. Roselle extract (20%, 40%, 60%, and 80%) was mixed with mango juice and stored in glass and plastic bottles at 4°C and 28°C. Total soluble solids, pH, titratable acidity, reducing sugar, color, vitamin C, tot...

Measurements of extracellular pH (pHe) in vivo have shown that the microenvironment in tumours is more acidic than in normal tissue. However, both human and animal tumour cells have been shown to have an intracellular pH (pHi) on the alkaline side of neutrality (pH 7.1-7.2). This gives rise to a reversed pH gradient between tumours and normal tissue which implies that cells within solid tumours...

At present, acid rain or snow is falling on most of the northeastern United States. The annual acidity value averages about pH 4, but values between pH 2.1 and 5 have been recorded for individual storms. The acidity of precipitation in this region apparently increased about 20 years ago, and the increase may have been associated with the augmented use of natural gas and with the installation of...

The quality of floral honey produced in Saudi Arabia was evaluated. All samples were analyzed for common physicochemical parameters like moisture contents, acidity, ash, pH, conductivity and heavy metal contents. All samples showed proper maturity, considering the low moisture percentage. The total acidity, below 50 meq/kg, in all the samples indicated the absence of undesirable fermentation. A...

Palm sap tapped from three varieties of date palm Phoenix dactylifera was analyzed during two tapping periods: winter and springtime. These samples were collected once-a-week during 14 weeks for each tapping period. Total soluble solids decreased during tapping period; however no significant variation was noted for pH and titrable acidity. The microbial count indicated that after an initial hig...

ABSTRACT: Acidophilus milk after preparation, with the defined characteristics of pH, titratable acidity and viable counts of Lb. acidophilus, was kept at the refrigerator (5 °C) and changes of above mentioned parameters were evaluated during 21 days at 7-day intervals. The obtained results showed that the titratable acidity of product significantly (p≤0.05) increased over storage period, demon...

Soil acidity is a major constraint on plant productivity. Arbuscular mycorrhizal (AM) fungi support plant colonization in acidic soil, but soil acidity also constrains fungal growth and diversity. Fungi in extreme environments generally evolve towards specialists, suggesting that AM fungi in acidic soil are acidic-soil specialists. In our previous surveys, however, some AM fungi detected in str...
