  • Meningitis L. monocytogenes causes ~5–10% of all cases of community-acquired bacterial meningitis in adults in the United States. Case-fatality rates are reported to be 15–26% and do not appear to have changed over time. This diagnosis should be considered in all older or chronically ill adults with "aseptic" meningitis. The presentation is more frequently subacute (with illness developing over several days) than in meningitis of other bacterial etiologies, and nuchal rigidity and meningeal signs are less common. Photophobia is infrequent.

  • This study investigates impacts of climate change on water resource in the Huong River basin in the Central Vietnam. Hydrological responses of six climate change scenarios were calculated. Results reveal that climate change would cause significant increase in rainfall in wet season resulting in an increase in river flow. By contrast, the decreasing trend of river flow in dry season is a consequence of the decline of rainfall and increase of evapotranspiration under most scenarios. Sea level rise coupled with the lowering of river stages may exacerbate salinity intrusion.

  • Climate change (CC) is one of the most significant challenges facing human beings in the 21st century. CC will seriously affect lives, production and environment worldwide. It also leads to the increasing temperature and one of its consequences is sea level rise, resulting in unpredicted changes of the river flow. This may cause more severe floods, serious drought and water shortage, further to continent of the salinity intrusions and negatively effect on the human’s lives, socio-economic development.

  • Greenhouse gases are accumulating in Earth’s atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. Temperatures are, in fact, rising. The changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability. Human-induced warming and associated sea level rises are expected to continue through the 21st century.

  • Testosterone also affects various other tissues in the male. Testosterone causes pubic and underarm hair growth, causes changes in body propor- tions, increases muscle tissue, and deepens the voice. Testosterone may influence the development of acne and the beginning of body odors from bacteria attracted to sweat glands. Because none of these characteristics are directly related to sexual reproduction, they are called secondary sex characteristics. In males, the level of testosterone in the body remains much the same for about 40 years after puberty.

  • In recent years, Nhat Le estuary has been accreted due to the development of a spit bar in the south bank, which obstructs the waterway navigation, the flood drainage and causes erosion in the north bank endangering the infrastructures of Dong Hoi city. This study shows the simulation of short-term and long term bed level changes in 10, 50 and 100 years of the estuary and the impacts of applied structural solutions using Delft3D, a model developed by Delft Hydraulics.

  • Global warming is the rising average temperature of Earth's atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century, Earth's average surface temperature has increased by about 0.8 °C, with about two thirds of the increase occurring since 1980. Warming of the climate system is unequivocal, and scientists are more than 90% certain that most of it is caused by increasing concentrations of greenhouse gases produced by human activities such as deforestation and the burning of fossil fuels.

  • Climate change is a very real and urgent global issue. Its consequences are being experienced every day. We read about it in newspapers, hear it debated in Parliament and our children learn about it in school. It’s a problem we all share, because every single country will be affected. Together, today, we must take action to adapt to it and stop it — or, at least, slow it down. your essential guide It’s now clear that the emission of man-made greenhouse gases is causing climate change. The rate of change began as significant, has become alarming and is simply unsustainable in the...

  • Thus, in living cells, the rates of anterograde and retrograde transport between the two organelles appear to have a substantial effect on the morphology of the Golgi. The effect of the balance between anterograde and retrograde transport on the morphology of the ER remains to be explored. Recently, increasing evidence has suggested that alteration in Golgi morphology during mitosis is not a passive process but rather an active one, which is highly coordinated with entry into mitosis and its progression.

  • 7 Exotic Species and Their Control The invasion of ecosystems by exotic species is a major environmental problem that has become widely recognized (Culotta, 1991; Mack et al., 2000; Malakoff, 1999). This phenomenon is occurring globally and causing changes to ecosystems, along with associated economic impacts.

  • Impoverishing the local resource base can impoverish wider areas: deforestation by highland farmers causes flooding on lowland farms; factory pollution robs local fishermen of their catch. Such grim local cycles now operate nationally and regionally. Dryland degradation sends environmental refugees in their millions across national borders. Deforestation in Latin America and Asia is causing more floods, and more destructive floods, in downhill, downstream nations. Acid precipitation and nuclear fallout have spread across the borders of Europe.

  • The ocean absorbs a significant portion of carbon dioxide (CO2) emissions from human activities, equivalent to about one-third of the total emissions for the past 200 years from fossil fuel combustion, cement production and land use change (Sabine et al., 2004). Uptake of CO2 by the ocean benefits society by moderating the rate of climate change but also causes unprecedented changes to ocean chemistry, decreasing the pH of the water and leading to a suite of chemical changes collectively known as ocean acidification.

  • The medical consequences of operating outside of the normal boundaries of a well tuned musculo-tendinous system are also poorly understood, although clearly recognized in the persistent atrophy experienced in microgravity despite rigorous exercise programs. Muscle force generation is length and velocity sensitive. The process is repetitive in the sense that muscles will always generate force based on their length-tension and forcevelocity properties, causing tendon deformation.

  • Climate change is happening now. Climate-induced disasters are occurring in the Asia Pacific region, where a distinctly increasing trend has been observed in recent decades. This shows that the region is the most disaster prone, compared with other parts of the world. Studies on the causes of disaster in many affected regions suggest that in a typical disaster, cities with high population density see increases in mortality and number of people affected. Increased economic losses within the region are also inevitable.

  • Popular American films penetrate nearly every aspect of contemporaryWestern life, and to an only somewhat lesser degreemost all cultures of the world. Historically, there are powerful sociological, cultural, economic, and even political reasons for this, but we would also argue thatHollywood-style filmhas evolved so that filmmakers havemore control over the attention of filmgoers (Smith 2006) and, in essence, the humanmind. One source of evidence concerns the changing pattern of shot lengths.
