Common central air conditioning problems occur when rooms are closed off and air flow through the home is disrupted. On the other hand, if you have a room air conditioner, the opposite is true. And are is improper operation. Be sure to close your home's windows and outside doors to isolate the room or a group of connected rooms as much as possible from the rest of your home. For a list of common air conditioner problems and what to look for, check out our Energy Saver 101 infographic on home cooling.

Other common problems with existing air conditioners result from faulty installation, poor service procedures, and inadequate maintenance. Improper installation of a central air conditioner can result in leaky ducts and low airflow. Many times, the refrigerant charge (the amount of refrigerant in the system) does not match the manufacturer's specifications. If proper refrigerant charging is not performed during installation, the performance and efficiency of the unit is impaired. Unqualified service technicians often fail to find refrigerant charging problems or even worsen existing problems by adding refrigerant to a system that is already full. Learn what to ask for when hiring a technician to maintain your air conditioner.

Talk with a doctor if you are experiencing noticeable changes in your memory. A doctor can perform tests and assessments to help determine the source of memory problems. Your health care provider may also recommend that you see a neurologist, a doctor who specializes in treating diseases of the brain and nervous system.

Major, traumatic, or stressful life events can also cause memory problems. For example, someone who has recently retired or who is coping with the death of a spouse may feel sad, lonely, worried, or bored. Stress and negative emotions are powerful. Trying to deal with such life changes and emotions leaves some people confused or forgetful.

These memory problems from negative emotions are usually temporary and will improve as the stress and emotions fade. Being active, socially engaged, and experiencing a sense of accomplishment by learning new skills can help with both memory and improving mood. If memory problems persist after a few weeks, talk with your doctor as this may be a sign of something more serious.

Finding the cause of memory problems is important for determining the best course of action. Once the cause is diagnosed, you and your doctor can determine the best treatment plan. People with memory problems should make a follow-up appointment to check their memory every six to 12 months.

This guide and the associated package of online materials provides a reference point for planning or delivering health and social responses to drug problems in Europe. The most appropriate responses will depend on the specific drug problems, the contexts in which these occur and the types of intervention that are possible and socially acceptable. By providing key information on some of the most important drug issues for Europe and the responses available, this guide aims to assist those involved in tackling these challenges to develop new programmes and improve existing ones.

Findings In this cohort study of 6595 US adolescents, increased time spent using social media per day was prospectively associated with increased odds of reporting high levels of internalizing and comorbid internalizing and externalizing problems, even after adjusting for history of mental health problems.

Importance Social media use may be a risk factor for mental health problems in adolescents. However, few longitudinal studies have investigated this association, and none have quantified the proportion of mental health problems among adolescents attributable to social media use.

Conclusions and Relevance Adolescents who spend more than 3 hours per day using social media may be at heightened risk for mental health problems, particularly internalizing problems. Future research should determine whether setting limits on daily social media use, increasing media literacy, and redesigning social media platforms are effective means of reducing the burden of mental health problems in this population.

For example, it is now well-known that tobacco smoke can cause many cancers, methamphetamine can cause severe dental problems, known as meth mouth, and that opioids can lead to overdose and death. In addition, some drugs, such as inhalants, may damage or destroy nerve cells, either in the brain or the peripheral nervous system (the nervous system outside the brain and spinal cord).

In order to celebrate mathematics in the new millennium, The Clay Mathematics Institute of Cambridge, Massachusetts (CMI) established seven Prize Problems. The Prizes were conceived to record some of the most difficult problems with which mathematicians were grappling at the turn of the second millennium; to elevate in the consciousness of the general public the fact that in mathematics, the frontier is still open and abounds in important unsolved problems; to emphasize the importance of working towards a solution of the deepest, most difficult problems; and to recognize achievement in mathematics of historical magnitude.

The prizes were announced at a meeting in Paris, held on May 24, 2000 at the Collge de France. Three lectures were presented: Timothy Gowers spoke on The Importance of Mathematics; Michael Atiyah and John Tate spoke on the problems themselves.

Following the decision of the Scientific Advisory Board, the Board of Directors of CMI designated a $7 million prize fund for the solutions to these problems, with $1 million allocated to the solution of each problem.

It is of note that one of the seven Millennium Prize Problems, the Riemann hypothesis, formulated in 1859, also appears in the list of twenty-three problems discussed in the address given in Paris by David Hilbert on August 9, 1900.

If it is easy to check that a solution to a problem is correct, is it also easy to solve the problem? This is the essence of the P vs NP question. Typical of the NP problems is that of the Hamiltonian Path Problem: given N cities to visit, how can one do this without visiting a city twice? If you give me a solution, I can easily check that it is correct. But I cannot so easily find a solution.

Climate change, like problems in education policy and public health, is a wicked problem. It avoids straightforward articulation and is impossible to solve in a way that is simple or final. Our changing conversations around climate science and conservation, the unique regional factors that determine the local consequences of climate change, and our ability to present endless possible solutions (as well as the irreversibility of these solutions) require we approach climate change with holistic and collaborative reasoning in search of long-term, future focused solutions.

The Adobe Creative Cloud Cleaner tool is intended for advanced computer users and can fix many common problems (such as removing old Adobe software, cleaning corrupt installation files, and fixing your host files to establish a connection with Adobe servers).

The mission of the Center for Problem-Oriented Policing is to advance the concept and practice of problem-oriented policing in open and democratic societies. It does so by making readily accessible information about ways in which police can effectively and equitably address specific crime and disorder problems.

Background:Ā  Cross-sectional studies indicate a high prevalence of mental health problems among college students, but there are fewer longitudinal data on these problems and related help-seeking behavior.

Methods:Ā  We conducted a baseline web-based survey of students attending a large public university in fall 2005 and a two-year follow-up survey in fall 2007. We used brief screening instruments to measure symptoms of mental disorders (anxiety, depression, eating disorders), as well as self-injury and suicidal ideation. We estimated the persistence of these mental health problems between the two time points, and determined to what extent students with mental health problems perceived a need for or used mental health services (medication or therapy). We conducted logistic regression analyses examining how baseline predictors were associated with mental health and help-seeking two years later.

This report provides an overview of the health problems in Arkansas. The health problems discussed are life expectancy, infant mortality and health literacy. Other chapters address important issues that affect our health such as living in rural Arkansas, having unequal opportunities and growing factors that may affect how our health problems are solved. Also, the report meets two of the three prerequisites for applying for public health accreditation through the Public Health Accreditation Board.

Encountering wild animals usually fills people with excitement and wonder. However, there are times when being face-to-face with nature poses a new set of problems. Below, we have provided links to information on how to deal with nuisance wildlife and sick, injured or orphaned wildlife. 0852c4b9a8
