- What policy drivers could states and the federal government use to bring quality up and cost down? Are the
current efforts effective?
2.Go to the World Press Review online (www.worldpress.org (Links to an external site.)) and pick a
controversial news topic discussed by several newspapers. Identify characteristics of those newspapers (such
as political leaning, region) that might explain the different points of view expressed on the topic.
3..For this week’s question, I want you to explore a current public health issue that is threatening our nation at
large. A few DQs ago, I mentioned climate change as being a public issue of concern for the nation. Two other
issues of concern are gun violence and immigrant health. In fact, former presidential candidate Elizabeth
Warren addressed the latter as part of her health reform platform in her presentations. Please select one of the
three issues and concisely summarize the issue with some facts/figures, the interest groups
supporting/opposing it and the ethical principles to consider in any reform. I.e. The NRA and the right to bodily
defend yourself (autonomy) as well as written in the Constitution.
he dynamic rheological measurements were carried out at the linear viscoelastic region of the processed cheese samples. The frequency sweep test of the processed cheeses showed that all samples had Gʹ > Gʺ, indicating that solid-type structures were present and both parameters increased with frequency (Fig 2). Gʹ and Gʺ of PCT samples were lower than Gʹ and Gʺ of control sample. However, there were no significant difference (p>0.05) between the Gʹ and Gʺ values of PCT samples (Fig 6). These results showed that tomato powder decreased the solid like behavior of PC. One of reasons for this effect of tomato powder could be the effect of stirring and heating of PC while making the samples. On the other hand, Gʹ and Gʺ of PCA increased with increasing of frequency and were higher than those of control sample. However, the changes in Gʺ were not as large as changes in Gʹ (Fig 3). It means that asparagus powder led to a more elastic structure in the PC. One explanation for this behavior of asparagus could be existence of dietary fiber. Dietary fiber consists primarily of carbohydrate polymers (non-starch polysaccharides) that are components of plant cell walls, including cellulose, hemicelluloses and pectins, as well as other polysaccharides of plant or algal origin, such as gums and mucilages and oligosaccharides such as inulin36. Asparagus is a natural sources of fructo-oligosaccharides and inulin37. Dietary fibers have some special properties such as water holding capacity and viscosity, or gel-forming capacity. Water holding capacity is the amount of water that is retained by known weight of dry fibers under specified conditions. In general, the polysaccharide constituents of dietary fibers are strongly hydrophilic. Water is held on the hydrophilic sites of the fiber itself or within void spaces in the molecular structure. Viscosity is a physicochemical property associated with dietary fibers especially soluble dietary fibers such as gums, pectins, psyllium, and β-glucans. Viscosity, or gel-forming capacity, is related to a fiber’s ability to absorb water and form a gelatinous mass. Water soluble fibers are the major component that would increase the viscosity of a solution38. Thus, there is two way for asparagus powder to increase the elastic behavior of PC. One way is by absorbing the moisture of PC and forming a gel like solution and second way could be attributed to the formation of polysaccharide network throughout the casein matrix. With increasing concentration of asparagus, more intensive interactions between its fiber chains take place, leading to the formation of a denser network structure. Similar results were reported with k-carrageenan and ι-carrageenan39. Also, Ribeiro et al.40 reached similar conclusions, i.e>GET ANSWER
