Use of Drones in Aerospace/Defense

April 25, 2017

The development of unmanned aerial systems, or drones was initially for military purposes. As these aerial systems did not require an onboard pilot, they were seen as a useful weapon on the battlefield. Not only does a drone decrease the mortality rate of the soldiers, it also provides the military a chance to spy on the enemy in a discrete manner.Drones have become an important component of national defense for the following reasons.· A drone is an unmanned vehicle, that is, it does not require any one to be on it to be controlled. This is possible because it can be controlled using a remote control. Though it is mandatory that it is still controlled by a trained pilot, it does not require the pilot to go with it.

· The US military has been using drones to search for terrorists in Afghanistan and have proved how useful they are for conducting covert military operations.· Drones can be used for various purposes such as searching for hidden terrorists, gunning the terrorists down in their own areas and searching for the hidden landmines using hyperspectral imaging sensors.· Keeping an eye on the air space of the country.· Keeping a check on the borders of the country without threatening the lives of the most precious soldiers.The use of the US Army’s Global Hawk in the combat field of Afghanistan has already made news. This has triggered a race between countries to own and develop this technology as soon as possible. Countries like UK and China and India are already way ahead in the research and development of drones for their respective defense forces.The use of drones even by the army is not only for combat and espionage purposes. This technology is largely being developed for the times when a crisis hits the nation. The military is trying to use drones in areas that have suffered fire or earthquake where the military and air force is called in to rescue people. This is the humanitarian aspect of the use of drones. Drones are sent in difficult to reach places to search for survivors. When the images from a drone shows the presence of any survivor, special teams are sent in to carry out rescue operation. This has saved many lives and is sure to save a number of lives in future too.

The countries that are trying to be the controlling factors in the world need to have this technology soon. UK has started by bringing together all of its top engineers to develop homemade UAVs and there were news about the flight of their first UAV named Taranis.The use of UAVs cannot replace the fighter jets or the satellites, however, they can be used for surveillance missions that can’t be performed by fighter jets as they are too big and therefore can be spotted quite easily by radar. Drones are definitely one of the “must haves” for any good army in the future.

How Effective Is Weight Loss Surgery?

April 24, 2017

For severely overweight individuals that have failed to see results from diet and exercise alone, weight-loss surgery has become the safest and most effective means of achieving significant weight loss. In fact, studies have shown that with diet and exercise alone, nearly 95% of obese patients will gain all the lost weight back within 5 years. On the other hand, long-term success rates for weight-loss surgery – including the LAP-BAND procedure – are remarkably high, allowing patients to maintain a loss of between 50-70% of their excess body weight. Though there are many factors that can impact an individual patient’s weight-loss success, weight-loss surgery is simply the most effective long-term weight loss and healthy lifestyle solution for severely obese patients.Studies show that most patients that undergo weight-loss surgery will lose between 50-70% of their excess body weight within the first three years following their procedure. Those that undergo gastric bypass surgery will lose excess body weight more rapidly in the first 12 months than those that choose LAP-BAND surgery. However, gastric bypass patients typically experience a greater number of complications and side effects than LAP-BAND patients, as the LAP-BAND procedure allows for more gradual and natural long-term weight loss.From a clinical perspective, a weight-loss surgery is considered successful when the patient loses at least 50% of their excess body weight and keeps the weight off for at least five years. While important lifestyle changes need to be made to ensure that the weight loss is maintained in the long term, studies have shown that most weight loss surgery patients are able to maintain a 50-60% loss of excess body weight 10 years after the surgical procedure. However, it is important to note that a weight loss of just 10% of total body weight can begin to have positive health effects in resolution of obesity-related condition like asthma, gastric reflux (GERD), and diabetes. As weight-loss surgery is usually performed on patients that are at least 75-100 pounds overweight or have a Body Mass Index (BMI) of at least 35 with a health condition, overall weight loss can range anywhere from 40 pounds to over 100 pounds. But the patient is really the leader behind achieving these results.

While patients will certainly look and feel better after weight-loss surgery, there are also numerous health benefits associated with successful weight loss. In most cases, health conditions that develop as a result of excessive body weight or are worsened by obesity can be improved upon or, in some cases, remedied by weight-loss surgery.But there are other ways to measuring success with weight-loss surgery, like the LAP-BAND System. For instance, many weight loss surgery patients take great pride in being able to perform certain activities that may not have been possible for a number of years, like crossing their legs, bending over to tie a show, walking up stairs without being easily winded or sitting comfortably in an airplane seat.While most patients that undergo weight-loss surgery experience incredibly positive results, there are many factors that can impact the overall success of an individual patient’s procedure and follow-up treatment. Here are some important factors to consider as you try to determine whether weight loss surgery is right for you.Pre-surgery WeightGenerally speaking, the higher a patient’s pre-surgery weight or BMI, the more excess weight the patient can lose after surgery. However, recipients of weight-loss surgery with less excess body weight will eventually come closer to their ideal weight when committed to long-term diet and exercise. Also, resolution or improvement in obesity-related diseases can occur with even moderate amounts of weight. Often many diseases can become closer to cured than improved with earlier intervention at a lower weight.Overall HealthWhile pre-existing health conditions can impact the overall success of weight-loss surgery (for instance, patients with type 2 Diabetes typically lose less excess body weight after surgery), studies have shown that many ailments linked to obesity are either improved upon or fall into remission after a successful procedure. For instance, a 2000 study performed on 500 weight loss surgery patients showed that nearly 96% of health conditions associated with obesity – such as high blood pressure, depression, sleep apnea, back pain and diabetes – improved greatly following loss of excess weight and long-term commitment to diet and exercise.Surgical ProcedureAs there are potential risks and complications associated with any surgical procedure, potential patients should always seek to have their weight-loss surgery performed by a trusted medical staff. Prospective patients should inquire about their surgeon’s success rates with weight-loss surgery and listen to the experiences of former patients. Additionally, a patient’s weight-loss success may also be impacted by the quality of post-surgery care and counseling provided by their bariatric outpatient facility.Diet and ExerciseAs diet and exercise are two of the most important factors in any weight loss plan, patients with the physical ability to exercise after weight-loss surgery have increased chances of meeting their goals. To maintain the weight loss achieved by surgery, both exercise and healthy eating habits must become integral parts of a patient’s lifestyle.

CommitmentThe ability to remain committed to suggested dietary guidelines, exercise regimens and any follow-up care recommended by the bariatric outpatient facility is important for both short-term weight loss and long-term weight management.MotivationPatients that are motivated to lose weight and willing to follow through with diet and exercise prior to receiving weight loss surgery may experience greater levels of success immediately following the procedure and in the long term. Most people did not find themselves severely obese overnight. It took years to reach that weight and therefore patients should be patient with the weight-loss process, which will also not occur overnight. Successful patients find small victories along the way to celebrate and stay motivated.SupportAs weight-loss surgery will require some time away from everyday activities, it is important to have the support of family, friends and coworkers before undergoing any surgical procedure. Furthermore, as the ongoing weight-loss process following bariatric surgery may require a certain level of emotional support, prospective patients may want to establish a support network – including friends and family members that can join in on exercise and healthy eating.Considering that significant weight loss can not only remedy many health concerns, but also improve an individual’s quality of life, the potential benefits of weight-loss surgery are plentiful. For severely overweight individuals that are unable to lose weight via diet and exercise alone, weight-loss surgery is the most effective method of losing weight – and keeping the weight off.
