moistened the flour.The flour and corn starch were both visible, even after being mechanically agitated. Heterogeneous mixture. Incorrect Conclusion The hypotheses about the solutions using water as a solvent were correct. The hypothesis was that the solutes would all dissolve in the water. This was correct, because water is the universal solvent. It is capable of dissolving more substances than any other solvent in the world. The hypotheses were wrong for the last two mixtures. It was…

because it contains a pigment molecule known as flavin. This means that it changes colours depending on the quantity of hydrogen ions in the solution. The red cabbage can produce red, purple or blue juice. The colour it produces depends on the pH of the water it has been mixed with.…

2015). The finding of optimum salinity conditions for each species will increase fish productions and brackish water areas will be used more efficiently. Several studies indicate that marine fish grow rapidly on isosmotic water salinity of 10 to 15 (Imsland et al., 2008; Arjona et al., 2009;…

considerable amount of water which is commonly called sap. Water is contained in wood as either bound water or free water. The bound water is held within cell walls by bonding forces between water and cellulose molecules, while the free water is contained in the cell cavities and is not held by these forces. The amount of water in wood can be calculated and expressed as a percent of the dry weight is called the “Moisture Content” (MC). The hygroscopic nature of wood cause the water movement,…

Chitin is the second most abundant natural polysaccharide consisting of β(1→ 4)-linked N-acetyl-D-glucosamine (GlcNAc) units in a linear form. Chitin is insoluble in water and mainly exists in two crystalline (α- and β-) forms. The α-chitin consists of sheets of tightly packed alternating parallel and antiparallel chains (1) and is abundant in the exoskeleton of arthropods, insects, fungi, and yeast cell walls. The chains are arranged in parallel orientation in β-chitin (2), which occurs less…

An absorbable suture is defined as a surgical suture material prepared from a substance that can be dissolved by body tissues and is therefore not permanent [1]. Any suture, which loses its tensile strength within 60 days, is considered an absorbable suture. The ideal absorbable suture has high tensile strength, low reactivity, good security and delayed absorption time. They can be classified as natural absorbable sutures or synthetic absorbable sutures. The only natural absorbable suture is…

organic Tb3+ co activated sulfamic acid single crystals are grown in unidirectional (100) from aqueous solution by a slow evaporation technique. Single crystal X-ray diffraction studies confirm that the grown crystal belongs to orthorhombic crystal system with space group Pbca. The grown crystals of single crystal XRD and…

Hohn et al. (1986) described a water column up to 1.70 m. In the present study, there was a greater tendency of accumulation of fine material, with little concentration of carbonates, at the highest depths. As expected, the accumulation of fine sediment was also associated with higher concentrations of organic matter. The results obtained in the bathymetric survey showed occurrence of a sedimentation process in this lagoon. Some physico-chemical parameters of the water column were determined by…

BSE, the E-coli virus were not confined to a single region or country, nor do they spread out to certain social groups in society exclusively. It is widely known fact that, environmental hazards have no boundaries and are universalized by water, air, food chains and winds. Therefore, the question is who is not worried about the environment? It is obvious that everyone should be concerned of the environment in which we live, whether rich or poor, developed or developing nations. This knowledge of…

mustard seeds. Mustard oil is obtained by cold compression of the mustard seeds and by infusing this extracted oil with other oils to get the final product. Essential mustard oil is obtained by grinding the mustard seeds. These are then mixed with water and oil is obtained by the process of distillation. All varieties of mustard oil are yellow in color and have a distinct aroma and a pungent smell. What does mustard oil contain? Mustard…
