Textural properties, water-holding capacity, and color characteristics of alkali-extracted chicken dark meat have been studied. Alkali extraction was carried out at 4 different pH values (10.5, 11.0, 11.5, and 12.0). At higher pH of extraction, cooking loss and water loss were found to be significantly decreased (P < 0.05). The lightness (L* value) of the recovered samples treated at higher pH ...

BACKGROUND AND AIMS The use of sugar by dental plaque microorganisms leads to acid formation from the bacteria metabolism, which determines a decrease of pH onto teeth surfaces. The value of the critical pH is 5.2-5.5. We aimed to evaluate the capacity of patients to change their diet towards caries prevention after acknowledging the values of saliva parameters (pH, buffer capacity). MATERIAL...

BACKGROUND Due to the extensive use of phosphates in industry, agriculture and households, the phosphate - γ-alumina interactions are important for understanding its detrimental contribution to eutrophication in lakes and rivers. In situ Fourier transform infrared (FTIR) spectroscopy can provide more detailed information on the adsorbate-adsorbent interaction and the formation of hydrogen bonds...

The effect of different pH values on rumen lipolysis and biohydrogenation was investigated during incubations of the rumen contents with 40 or 80 mg of soybean oil as the sole substrate. Mean pH values studied were 6.8, 6.3, 6.0, 5.6 and 5.2. Lipolysis was calculated from the decrease in fatty acids present in triacylglycerols (TAG), as well as from the accumulation of free fatty acids (FFA) du...

Pleural fluid pH is of greatest value for the assessment of patients whose pleural effusion is due to respiratory infection (pneumonia), but that is not the limit of the test’s utility. In addition to the clinical value of measuring pleural fluid pH, the article includes consideration of measuring method and sample collection; it begins, however, with a brief discussion of some relevant anatomy...

The synthesis of pure and well dispersed lutetium aluminum garnet (LuAG) powder is crucial and important for the preparation of LuAG transparent ceramics. In this paper, high purity and well dispersed LuAG powders have been synthesized via co-precipitation method with lutetium nitrate and aluminum nitrate as raw materials. Ammonium hydrogen carbonate (AHC) was used as the precipitant. The influ...

Acid mine drainage (AMD) is the outflow of acidic water from metal mines or coal mines. When exposed to air and water, metal sulfides from the deposits of the mines are oxidized and produce acid, metal ions and sulfate, which lower the pH value of the water. An open limestone channel (OLC) is a passive and low cost way to neutralize AMD. The dissolution of calcium into the water increases the p...

In this research, nanocrystalline Co-Fe coatings were electrodeposited on copper substrate. The influence of current density on different properties of the films at two pH levels was investigated. All the coatings showed nodular structure with rougher morphology at higher current densities. Due to anomalous deposition at higher current density, the amount of iron content increased and reached i...

In this work, the weak polyelectrolyte (PE) adsorption on a strong cationic surface is studied with constant pH Monte Carlo simulations using coarse-grained model. When large number of PE chains added to system, adsorbed amount vs curve exhibits non-monotonic behavior, appearance maximum close intrinsic pKa0-value titratable groups. The apparent pKa-value shows non-trivial tendency depending pH...
