Abstract This research concentrates on the use of color Doppler sonography when diagnosing endometrial malignancies. The writer looks at how color Doppler sonography is the most effective method of identifying malignancies within the reproductive organs including the uterus.
The writer explains that this is because color Doppler sonography allows physicians to distinguish benign masses from malignant masses more easily than do traditional ultrasound, endovaginal ultrasound and transvaginal sonography techniques. T

From the Paper "As with many malignancies or cancers of the genital tract or reproductive system, manifestation or symptoms of endometrial malignancies often are mistaken for symptoms of other common problems. Women with endometrial malignancies often do not seek treatment immediately because they believe their symptoms to be the result of some other ailment, even common problems like yeast infections (Birnbaum, 1991). Unfortunately such assumptions on behalf of the patient or by doctors can be deadly. This is one reason all symptoms, regardless of their severity, should be reported to a professional as soon as possible for evaluation and treatment recommendations.
"Symptoms of endometrial malignancies may include changes in vaginal discharge, discharge accompanied by strong odors, pain in the abdomen or pelvis and other symptoms, symptoms that often mimic those of other diseases."
Abstract This paper explains that, in order to battle effectively criminal scum in Hell's Kitchen, blind superhero Daredevil, from the film "Daredevil", must use the Doppler effect to dodge bullets and to envision his surroundings. The author points out that a radioactive accident left Daredevil blind as a child but intensely amplified his remaining four senses. The paper relates that, to understand how Daredevil uses the Doppler effect, the viewer must know that sound waves are the result of vibrating particles in any material. The author continues that the Doppler effect is the frequency change of a moving sound source. The paper describes two instances, in the film, where Daredevil knew where the bullet was without seeing it by using the Doppler effect.
From the Paper "Daredevil uses sonar by listening to the water droplets echo from hitting the ground around him as it reflects or bounces off an object. He can envision his surroundings by establishing that the longer it takes for the echo of the water droplet to come back, the further away the object is. Recall that when he uses the Doppler Effect he learns if the object is moving toward or away from him. With his super hearing abilities, he can tell if the object that the sound waves are bouncing off of is as small as a grain of rice or as big as a truck."
Abstract The paper reveals that tornadoes are one of nature's most powerful forces. The writer explores the strengths of a tornado, the type of damage it does and the steps that can be taken to warn communities of its possible arrival. The paper discusses the Doppler radar system that can detect a tornado while it is still in the sky, the tornado siren system and trained human storm chasers and spotters. The paper explains that one of the problems with tornadoes is their unpredictability, but as emergency management teams nation wide continue to improve, the public will become increasingly safer.

Conclusion
From the Paper "Out of all the natural disasters that can occur, tornadoes are often considered the most damaging and the most dangerous. While earthquakes are unpredictable, they have not developed a history in the United States of frequent occurrence or many deaths. Hurricanes, with the exception of Katrina usually provide enough advanced warning that the emergency management coordinators can provide notice to evacuate. Tornadoes, however, often strike with little or no warning and they can come in "swarms" during optimum weather conditions(Gugliotta, 2003)."
Abstract This report is designed to introduce the future officer to traffic radar. It explains to the future police officer the kind of radar units he/she may encounter on a job, how they work, public opinion of them and touches on the potential health hazards that radar units can present.
From the Paper "Since its introduction to traffic law enforcement in 1948, radar has been an integral component of vehicular speed measurement. Each year hundreds of thousands of dollars are collected in courts throughout the nation from motorists whose speed was monitored with the aid of this electronic instrument. Today, radars overall efficiency and effectiveness have been greatly enhanced. In spite of its great improvements, radar is currently being scrutinized, questioned, and challenged, not only for its reliability but also for the quality of operator training. "
Abstract This paper deals with the two different kinds of sonar techniques employed by bats throughout the world. The author further discusses bats that don?t use echolocation at all. The author then examines the conflicting studies that have been done on this biological phenomenon and explains how the process works.
From the Paper "Burton (1982) states that the majority of the Microchiroptera utilize FM based echolocation. In this type of echolocation the pulses of sound, or calls, last no longer than a few thousandths of a second and drop through nearly an octave. The few species that do not use FM echolocation utilize the CF based echolocation. With CF echolocation the calls last up to ten times longer than those of the bats that use the FM method, explains Burton. "
A discussion on peripheral arterial disease, also known as PAD, a chronic condition in which arteries that supply blood to the legs become blocked by a buildup of plaque.
Abstract The following paper examines the symptoms, diagnosis and treatment of PAD, a form of atherosclerosis, a progressive disease characterized by fatty deposits in the inner layer of the arteries, which gradually narrows the artery. The writer particularly focus on 'Raynaud?s' one of the forms of PAD which causes fingers and toes to turn blue and white with cold .
From the Paper \"It's important to remember that many people have PAD without having any symptoms. Such individuals are at higher risk for a stroke or heart attack. Research indicates that the risk for dying from heart disease is six times higher for people who have PAD, and PAD patients have a 30 percent risk of dying from a cardiovascular-related problem within five years after the initial diagnosis of PAD (University of Penn Health System). It is essential that anyone who has health problems or a lifestyle that could lead to PAD be aware of the symptoms of this potentially life-threatening disease, as see a doctor for any problems. Peripheral arterial disease can be controlled in most cases. People only need to be aware of the signs.\"
Abstract Echocardiography uses sound waves to examine the size, shape, and motion of various structures within the heart and is used to diagnose abnormalities of the heart valves and to assess cardiac function. The paper explains that this is a noninvasive test in which a microphone-like transducer directs towards the heart extremely high-pitched sound waves (which cannot be heard by the human ear), which reflects these waves thus producing echoes. This paper looks at the use of echocardiography in detecting congenital heart disease, especially in fetuses.
From the Paper "Fetal cardiac abnormalities are usually not diagnosed by routine ultrasonography, but detailed fetal echocardiography is a costly procedure and is usually performed only in high risk cases (5). However, Stumpflen, Stumpflen, Wimmer and Bernaschek found that cardiac abnormalities could be detected in a high proportion of low-risk fetuses. They offered detailed fetal echocardiography at 18-26 weeks of gestation to all women who attended an antenatal clinic. The study included 2181 women with no known risk factors, 540 with maternal risk factors of congenital heart disease, and 364 with sonographically detected abnormalities (5:854)."
Abstract This paper examines and analyzes the process of predicting tornadoes. The use of technologies such as Doppler radar and Optical Transient Detectors is discussed, as are meteorological indicators of tornado formation in supercell storms.
Abstract The paper discusses how current portable devices are changing imaging diagnostics. The paper focuses on GE's Logiq Book XP Ultrasound System and shows how it fulfills the market need for a relatively low cost, mobile and flexible ultrasound device. The paper looks at its advantages over existing systems and stresses how the GE Logiq Book XP is an important addition to the growing field of portable ultrasound devices.

Conclusions
From the Paper "Ultrasound technology bounces acoustic waves off samples, extracting images and data from the reflected signals by using relatively inexpensive electronics that switch between transmitting and receiving (Rollins, 2005). Ultrasound technology exists in a variety of forms from analog to digital, from pulsed to continuous wave, and from 2D to 3D to 4D images. One of the most advanced ultrasound systems is a continuous wave (CW) Doppler ultrasound that colorizes time-controlled images to calculate fluid velocities within the body (Allan, 2006; Tuite, 2005). Unfortunately, ultrasound technology isn't traditionally considered portable. CW Doppler ultrasound devices, in particular, require large computer boards to function (Allan, 2006). The end result is that most ultrasound equipment is large, ungainly, and expensive."
