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…

[53]. The direct band gap energy (Eg) of Tb3+: SA crystals grown by SEST and SR methods are found to be 4.20 eV, 4.10 eV respectively, which is in good accordance with the reported values [54]. The value of band gap of Sulfamic acid was found to decrease with increase in impurity concentration and it is found between 4 and 5 [54, 55]. Fig(7). Plot of α vs. photon energy. 3.6 Thermogravimetry (TG) and differential thermal analysis (DTA) Thermogravimetry (TG) and differential thermal…

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…

Distillation is the most widely used separation process in the chemical industries. The separation of mixtures by distillation depends on the relative volatilities between the components. The greater the relative volatilities, the easier the separation. DME can be used as an alternative raw material when it is converted to gasoline. The DME is converted to gasoline range hydrocarbons over a zeolite catalyst. In the gasoline production reaction, some reactions cause unwanted components which may…

Nowadays, air pollution has become one of the most impactful environmental problems. The quality of the air we breathe is in the decline for some decades now and its impacts are becoming more apparent year after year. The most major impact is the one it has on human health, from deteriorating the quality of our everyday life quality to being the root cause for a long list of health problems. The second big impact is the huge amount of money we need to spend on health care to treat all the health…

puncture so you'll either want to be a very strong swimmer or at least one that can hold their own if thrown into the water with a life jacket on. Someone that is more afraid of the water simply shouldn't be climbing into any type of inflatable boat. How to clean your kayak Most stores that carry inflatable boats also have a special cleaning agent available for them that may be used to clean harder types of stains like ground-in dirt, grass and oil. You can also use a mild cleaner on your boat…

Biofloc technology ensures sustainable aquaculture and protecting fish from variety of disorders and infections. Microbial flocs developed under the biofloc technology function as potential food sources for fish. Improved fish production, minimal water exchange and recycling of feed…
