...troubling most of the countries. China ranked 129 among the 142 environmental suspensibility evaluated countries; one of the reasons is the serious soil erosion. 19% of China's land is affected by soil erosion, which is one of the highest rates (Liu& Diamond, 2005: 1181). The statistics are thought-provoking, and the effects of soil erosion are significant. In fact, soil erosion is a part of a vicious circle. Scientists and technicians around the world are working hard to find out the better and more efficient ways to monitor and control soil erosion. Soil erosion is a progress in which soil particles are carried away by force such as water ,wind and gravity. Water and wind erosion are the most important erosion types classified by the erosive agents (Toy, Foster, and Renard, 2002: 55). In this report, the vicious circle of soil erosion, reduction of vegetations and sediments in river is discussed. Among the technologies applied in soil management, the one suitable for local condition is the best. Discussion Soil Erosion and Vegetation Soil Erosion's effects on Vegetation Plants absorb what they need from soil with roots. The topsoil provides the best environment for plants' roots with loose structure, enough air, and rich organisms, but it is removed firstly through soil erosion (Plaster, 1992: 413 ). First, soil erosion takes away the nutritions such as Nitrogen, phosphorus, and Potassium, which are essential to plants' health. If any of the essential nutritions is...

...Should You Get A Partial Denture For That Missing Tooth? Losing even one of your teeth can cause problems when it comes to speaking and chewing, as well as potentially causing other teeth to shift around in your mouth. It is important that you find a way to correct this missing tooth, for both health and cosmetic reasons. A partial denture is an affordable option that is completely removable. Here is what you need to know about each form of partial dentures. Immediate Dentures A temporary denture, also call an immediate denture, is a denture designed to not be used for very long. It’s typically for people that have an extracted tooth and are waiting to have another dental procedure performed to fix it. Until then, the immediate denture is used...

...This degeneration of the articular cartilage and joint can then cause bone-on-bone contact allowing for remodeling, thickening, and hardening of the subchondral bone and the formation of osteophytes, bony extrusions produced when bone is stressed or in contact with other bone (3). Several primary causes of osteoarthritis include aging, and the wear and tear of the cartilage involved in everyday activities. Also, any other specific degenerative or erosive joint diseases may bring upon osteoarthritis. Secondary causes of osteoarthritis can include mechanical stress, trauma, infection localized in the joint, or congenital abnormalities of the joint (2). The most affected areas are the knees, hips, spine, and hands with symptoms that include pain, stiffness, and loss of normal function of that area (4). While current treatments mentioned above adequately treat and help with the symptoms of osteoarthritis, they are not a cure. They do not stop the progression of OA, which means that a patient will always have the disease and will be affected by it unless surgical intervention is taken, like fusion, osteotomy, arthroscopy, or arthroplasty, to remove the affected joint (2). Platelet-rich plasma...

...culture, black identity, black institutions-have been distorted, remixed, and undermined by the logic of the current global economy. At stake is the preservation of a “modern” blackness—that blackness which was posited and circulated as a buffer against white supremacy, political disenfranchisement, slavery, Jim Crow segregation and the collusion of racist imaginations and commercial culture in the early 20th century. In many sectors,“blackness” is literally under siege. It is in this context that many of the contemporary tropes of “blackness” that circulate in commercial popular culture (niggas, hip-hop, the underclass, queers, etc.), particularly in popular music, film, and music video are perceived as threats to blackness—as tropes of an erosive and authentic blackness that is as threatening to the Black Public proper as “death” itself. Hip-hop has documented all of this, and more. There has not been a time since when N.W.A was as popular as a Public Enemy, or where the storytelling of a Slick Rick could fall alongside the pimp strolls of a Too Short, or Roxanne Shante was just as necessary as a Salt 'N Pepa or Queen Latifah.

...Explain your answer. Answer: I couldn’t make a good prediction about the average % dividing cells without any data or samples of breast tissue. However, if it’s anything like the cancerous tissues in my data tables above then it would probably be around 32.5% on the mitotic index. I got this number by finding the average of all the mitotic index percentages in table 4. 6. Consider the % dividing cells in normal lung, normal stomach, and normal ovarian tissue. Why do you think there are more cells dividing in the stomach and ovary tissue than in the lung tissue? Answer: In my opinion, the reason why stomach and ovary tissue has more cells dividing within them than the lung tissue is because the stomach and ovary tissue have a more erosive function then the lung tissue. For instance, the menstrual cycle is when the uterus sheds its lining once a month and then grows a new lining. Therefore, the ovary tissue will need enough cell division to replace the lining quickly. The stomach tissue also needs a good amount of cell division because it has to replace the stomach lining every five days. In conclusion, the reason why stomach and ovary tissue have more cell division is because they require a significantly faster generation of cells than the lung tissue needs to work properly. 7. This lab explores three common cancers. An additional form of cancer – Skin Cancer – used to be seen only in older individuals but is now seen in younger individuals, many in their early 20s...

... Basin area is the area from which water drains to a common stream and boundary determined by opposite ridges. 3.2.11 Drainage density (Dd) Drainage density is defined as the quotient of the cumulative length of the streams to the total drainage area and is expressed in length per unit area (Choubey and Jain, 1992). (3) Drainage density is a measure of how frequently streams occur on the land surface. It indicates the closeness of spacing between channels and is a measure of the total length of the stream segment of all orders per unit area. It reflects a balance between erosive forces and the resistance of the ground surface, and is therefore related closely to climate, lithology, and vegetation. Drainage densities can range from less than 5 km/km2 when slopes are gentle, rainfall low, and bedrock permeable, to much larger values of more than 500 km/km2 in upland areas where rocks are impermeable, slopes are steep, and rainfall totals are high (Huggett, 2007). (2) 3.2.12 Drainage frequency (Fs) It is also called channel frequency or stream frequency. It mainly depends on the lithology of the basin and reflects the texture of the drainage network. It is an index of the various stages of landscape evolution. The stream...

...Lupus Erythematous: The Butterfly Effect Lupus erythematosus (LE) first originated in 1833 by many physicians throughout the historical periods of; the classical period, the neoclassical period, and the modern period. During the classical period of the 1800s, lupus was first coined. It comes from the Latin word ‘wolf’ that attributed to the thirteenth century by physician Rogerius who used the word to describe erosive facial lesions that manifested from a wolf’s bite (Lupus Foundation of America, n.d.). In the neoclassical period of the 1900s, scientists discovered that there are many sub forms of lupus, the most common type known as systemic lupus erythematosus (SLE). SLE has many other forms of names such as discoid and disseminated lupus....

...Should sugary beverages be banned to sale? While some Americans today love to consume large sugary drinks, it does represent a national problem related to health issues. On the other side, restaurants, coffee companies, and consumers are worried about the Government proposal that might affect the companies’ business and the consumer’s freedom to choose any type of drink they want. The proposal prohibits the sale of any cup or bottle of sweetened drink larger than 16 fluid ounces. There are many reasons for restricting the sale and quantity of sodas in New York and this regulation is really just a wise decision that made public health one of the priorities in the City of New York. One reason we should ban selling the popular sugary drinks is that the consumption of big amounts cause obesity and other health diseases. Research has demonstrated a direct relationship between consumption of sugary drinks and an increase in the risk of overweight and obesity, which in turn promote many health conditions including: hypertension, coronary heart disease, type 2 diabetes, stroke, gall bladder disease, osteoarthritis, sleep apnea, respiratory problems, some cancers (endometrial, breast, and colon), and dyslipidemia (CDC, 2006). Although one of the national health objectives is to reduce the prevalence of obesity among adults, current data indicate that the circumstances are worsening (MMWR, 2006). This is particularly problematic because most of the daily calories come from sodas, energy...

Water quality administration should be procedure in system, there are plenty of system elements which have interrelationship with fluctuate uncertainties. The management of water quality should consider into two main influence factors. First, pollutants discharge from point and non-point source and human driven force. Second, indeterminate role of natural change to water quality, there are climate change and hydrology. In principal, a purpose of management for water quality is manufacturing of relationship between ecological capacity factors with socio-politico-economical level (Li, 2009), but the management has limitation by uncertainty of pollutants discharge quantity, soil erosive evaluation, the available of resources capacity, requirements stabilization of environment and policy regulation in all stakeholder.
