Carter County, Oklahoma

Carter County is a county in the U. S. state of Oklahoma. As of the 2010 census, the population was 47,557, its county seat is Ardmore. The county was named for a Cherokee who lived among the Chickasaw. Carter County is part of the Ardmore Micropolitan Statistical Area, it is a part of the Texoma region. Prior to statehood, the present Carter County, was part of Pickens County in the Chickasaw Nation of Indian Territory. After the Civil War, the government of the United States forced the Chickasaw government to allow railroads built across its territory; the Gulf and Santa Fe Railway built a line north from Texas to Purcell. In 1901-1903 the Arkansas and Choctaw Railway built a line from Arkansas to Ardmore. Oil production spurred further railroad development. In 1913-14, the Oklahoma, New Mexico and Pacific Railway constructed a line from Ardmore west to Ringling. In 1916, the Ringling and Oil Fields Railway laid tracks north from Ringling Junction to Healdton; these last two rail lines were abandoned in 1976.

Oil and gas production began early in the 20th century. The Healdton field opened in 1913, led to the development of Ardmore as a major oil production center. However, a disastrous fire occurred in Ardmore in 1915, when a railroad car exploded, killing 43 people and destroying much of the downtown. Ardmore and the local oil industry recovered, the city became a manufacturing center. Akron Tire and Rubber Company built and operated a plant in Ardmore as early as 1915. In 1970, Uniroyal built a tire plant there, it was acquired by Michelin North America in 1990. By the start of the 21st century, manufacturing was the largest component of the county economy. According to the U. S. Census Bureau, the county has a total area of 834 square miles, of which 822 square miles is land and 12 square miles is water; the county contains parts of several physiographic regions, including the Arbuckle Mountains, the Coastal Plains, the Red Bed plains and the Cross Timbers. The northern part of the county drains to the Washita River, while several creeks drain the southern part directly to the Red River.

The Healdton Field, encompassing Healdton and located in the western portion of Carter County, produces from the Pennsylvanian Healdton sands of the Hoxbar Group and the Ordovician massive carbonate Arbuckle Group. The field is located on the "Healdton uplift", a northwest-southeast trending anticline, which formed with the Wichita Orogeny, is 8 miles long and up to 3 miles wide; this was followed by deposition of the Healdton sandstones and shales on pre-Pennsylvanian eroded rocks and subsequent folding during the Arbuckle Orogeny. A prospector named Palmer drilled a shallow well, 425 feet, near an oil seep in the 1890s but Federal Law prohibited oil development on "Indian lands" until the early 1900s. Therefore, the discovery of the field is credited to the drilling of No. 1 Wirt Franklin in 1913.

Functional neurological symptom disorder

A functional neurological disorder is a condition in which patients experience neurological symptoms such as weakness, movement disorders, sensory symptoms and blackouts. In the past, the brain of a patient with functional neurological symptom disorder was believed to be structurally normal, but functioning incorrectly. Patients with FND were marginalized for much of the 20th century, with limited clinical and neuroscientific interest. Converging evidence from several studies using different techniques and paradigms has now demonstrated distinctive brain activation patterns associated with functional deficits, unlike those seen in actors simulating similar deficits. New research has uncovered pathways in the brain’s white matter that may be altered in patients with functional neurological disorder; the new findings advance current understanding of the mechanisms involved in this disease, offer the possibility of identifying markers of the condition and patients’ prognosis. Other terms have been used to describe these symptoms.

Symptoms of functional neurological disorders are clinically recognisable, but are not categorically associated with a definable organic disease. The intended contrast is with an organic brain syndrome, although the terms imply a level of certainty about causation, clinically unconfirmed. Subsets of functional neurological disorders include functional neurological symptom disorder, conversion disorder, psychogenic movement disorder/non-epileptic seizures. Functional neurological disorders are common in neurological services, accounting for up to one third of outpatient neurology clinic attendances, associated with as much physical disability and distress as other neurological disorders; the diagnosis is made based on positive signs and symptoms in the history and examination during consultation of a neurologist. Physiotherapy is helpful for patients with motor symptoms and tailored cognitive behavioural therapy has the best evidence in patients with dissociative attacks. There are a great number of symptoms experienced by those with a functional neurological disorder.

It is important to note that the symptoms experienced by those with an FND are real. At the same time, the origin of symptoms is complex since it can be associated with physical injury, severe psychological trauma, idiopathic neurological dysfunction; the core symptoms are those of motor or sensory function or episodes of altered awareness: Limb weakness or paralysis Blackouts – these may look like epileptic seizures or faints Movement disorders including tremors, myoclonus Visual symptoms including loss of vision or double vision Speech symptoms including dysphonia, slurred or stuttering speech Sensory disturbance including hemisensory syndrome Epidemiological studies and meta-analysis have shown higher rates of depression and anxiety in patients with FND compared to the general population, but rates are similar to patients with other neurological disorders such as epilepsy or Parkinson's disease. This is the case because of years of misdiagnosis and accusations of malingering. A systematic review found that stressful life events and childhood neglect were more common in patients with FND than the general population, although many patients report no stressors.

A diagnosis of a functional neurological disorder is dependent on positive features from the history and examination. Positive features of functional weakness on examination include Hoover’s sign, when there is weakness of hip extension which normalises with contralateral hip flexion, thigh abductor sign, weakness of thigh abduction which normalises with contralateral thigh abduction. Signs of functional tremor include distractibility; the patient with tremor should be asked to copy rhythmical movements with foot. If the tremor of the other hand entrains to the same rhythm, stops, or if the patient has trouble copying a simple movement this may indicate a functional tremor. Functional dystonia presents with an inverted ankle posture or clenched fist. Positive features of dissociative or non-epileptic attacks include prolonged motionless unresponsiveness, long duration episodes and symptoms of dissociation prior to the attack; these signs can be usefully discussed with patients. Patients with functional movement disorders and limb weakness may experience symptom onset triggered by an episode of acute pain, a physical injury or physical trauma.

They may experience symptoms when faced with a psychological stressor, but this isn't the case for most patients. Patients with functional neurological disorders are more to have a history of another illness such as irritable bowel syndrome, chronic pelvic pain or fibromyalgia but this cannot be used to make a diagnosis. FND does not show up on structural brain imaging such as MRI or CT scanning. However, this is the case for many other neurological conditions so negative investigations should not be used alone to make the diagnosis. FND can, occur alongside other neurological diseases and tests may show non-specific abnormalities which cause confusion for doctors and patients; the International Classification of Disease, due to be finalised in 2017 will have functional disorders within the neurology section for the first time. Functional neurological symptom disorder can rarely mimic many other conditions; some alternative diagnoses for FND that are considered include: Hemiplegic migraine Mul

Dynamic scraped surface heat exchanger

The dynamic scraped surface heat exchanger was designed to face some problems found in other types of heat exchangers. They increase heat transfer by: removing the fouling layers, increasing turbulence in case of high viscosity flow, avoiding the generation of ice and other process by-products. DSSHEs incorporate an internal mechanism which periodically removes the product from the heat transfer wall; the most important technologies for indirect heat transfer use flat surfaces. Their goal is to exchange the maximum amount of heat per unit area by generating as much turbulence as possible below given pumping power limits. Typical approaches to achieve this consist of corrugating the tubes or plates or extending their surface with fins. However, these geometry conformation technologies, the calculation of optimum mass flows and other turbulence related factors become diminished when fouling appears, obliging designers to fit larger heat transfer areas. There are several types of fouling, including particulate accumulation, sedimentation, generation of ice layers, etc.

Another factor posing difficulties to heat transfer is viscosity. Viscous fluids tend to generate deep laminar flow, a condition with poor heat transfer rates and high pressure losses involving a considerable pumping power exceeding the exchanger design limits; this problem becomes worsened when processing non-newtonian fluids. The dynamic scraped surface heat exchangers have been designed to face the above-mentioned problems, they increase heat transfer by: removing the fouling layers, increasing turbulence in case of high viscosity flow, avoiding the generation of ice and other process by-products. The dynamic scraped surface heat exchangers incorporate an internal mechanism which periodically removes the product from the heat transfer wall; the product side is scraped by blades attached to frame. The blades are made of a rigid plastic material to prevent damage to the scraped surface; this material is FDA approved in the case of food applications. There are three types of DSSHEs depending on the arrangement of the blades: Rotating, tubular DSSHEs.

The shaft is placed parallel to the tube axis, not coincident, spins at various frequencies, from a few dozen rpm to more than 1000 rpm. The number of blades oscillates between 1 and 4 and may take advantage of centrifugal forces to scrape the inner surface of the tube. Examples are the Waukesha Cherry-Burrell Votator II, Alfa Laval Contherm, Terlet Terlotherm and Kelstream's scraped surface heat exchanger. Another example is the HRS Heat Exchangers R Series. Reciprocating, tubular DSSHEs; the shaft is concentric to moves longitudinally without rotating. The frequency spans between 60 strokes per minute; the blades may vary in number and shape, from baffle-like arrangements to perforated disk configurations. An example is the HRS Heat Exchangers Unicus. Rotating, plate DSSHEs; the blades wipe the external surface of circular plates arranged in series inside a shell. The heating/cooling fluid runs inside the plates; the frequency is about several dozen rpm. An example is the HRS Spiratube T-Sensation.

Computational fluid dynamics techniques are the standard tools to analyse and evaluate heat exchangers and similar equipment. However, for quick calculation purposes, the evaluation of DSSHEs are carried out with the help of ad hoc empirical correlations based on the Buckingham π theorem: Fa = Fafor pressure loss and Nu = Nufor heat transfer, where Nu is the Nusselt number, Re is the standard Reynolds number based on the inner diameter of the tube, Re' is the specific Reynolds number based on the wiping frequency, Pr is the Prandtl number, Fa is the Fanning friction factor, L is the length of the tube, D is the inner diameter of the tube, n is the number of blades and the dots account for any other relevant dimensionless parameters; the range of applications covers a number of industries, including food, chemical and pharmaceutical. The DSSHEs are appropriate whenever products are prone to fouling viscous, heat sensitive or crystallizing. Pumpable ice technology Bott, T. R.. Design of Scraped Surface Heat Exchangers.

Fire HD

The Fire HD known as Kindle Fire HD, is a member of the Amazon Fire family of tablet computers. The eight generation family consists of: 7", 8.9", 7", 6" & 7", 8" & 10.1", 8", 8" & 10.1", 8" and 10.1". The first model was announced on September 6, 2012 and was available in two versions, 7" and 8.9". The 7" model was released in United States on September 14 France, Italy, United Kingdom on October 25 and in Japan on December 18; the 8.9" model was released on November 20 in United States, in Japan on March 12, 2013 in Germany on March 13, in India on June 27. On September 25, 2013, the Fire HD second generation was released; the price of the Fire HD 7" was reduced to $139, the processor speed was upgraded to 1.5 GHz, upgraded from "Android based" OS to a compatible proprietary fork of Android named Fire OS 3, removed the front camera, used a new form factor and decreased the available storage options. In addition, the Fire HD's successor the Kindle Fire HDX was introduced. On October 2, 2014, the Fire HD third generation was released, part of the Fire Tablet's fourth generation, with 6-inch and 7-inch touchscreen sizes.

In addition, the Fire HD Kids Edition was released, the same device as the Fire HD 6 except it comes with a case and one-year subscription to Kindle Freetime apps. In addition, the name "Kindle" was removed from the tablets' name. In September 2015, Amazon released a new range of Fire tablets with 7, 8, 10.1 inch sizes. The 7 inch was called the Fire 7, while the 8" and 10.1" were called Fire HD 8 and Fire HD 10 respectively. The Fire 7 is unique as it is, thus far, the lowest priced Fire tablet at $50. In September 2016, Amazon announced the new Fire HD 8 with Alexa starting at $90. In 2017, the seventh Generation Fire 7 Fire HD 8 were released; some differences between the 6th and 7th Generation HD 8 models were the price, the gyroscope removal, the increase of maximum SD card expansion, the better graphics chip. In September 2018, Amazon refreshed their Fire tablet line with the release of eighth Generation Fire HD 8/Kids Edition and HD 10; the price remained the same as last year's model with minor upgrade on the hardware where the external storage is expandable to 400GB.

On the software side, the 2018 model is preinstalled with Fire OS 6 that allows hands-free Alexa control. On October 7, 2019 Amazon announced an update to the Fire HD 10 which will be released on October 30, 2019; the major hardware differences compared to the previous version were replacement of microUSB with USB-C, a faster processor and battery life, 2 hours longer than the previous generation. The screen size and price remained unchanged. A new color option, has been added; the Fire tablets feature multi-touch touchscreen LCD screens. The first generation 7" model contains a Texas Instruments OMAP 4460 processor, while the 8.9" model uses an OMAP 4470 processor. All three models feature Dolby stereo speakers; the 7" model's speakers are dual-driver. The device has two Wi-Fi antennas on the 2.4 GHz and 5 GHz bands which utilize MIMO to improve reception. The Fire HD added Bluetooth connectivity allowing users to connect an array of wireless accessories including keyboards; the first generation models have an HDMI port.

In June 2016, Amazon released a version of the Fire HD 10 that has an aluminum exterior instead of plastic like the other Fire tablets, is available at the same price as the plastic version. The 2012 models use software that introduced user profiles for sharing among family members and the ability to place absolute limits on total usage or usage of individual features, called FreeTime, tracks the user's reading speed to predict when the user will finish a chapter or book; the OS is based on a version of Android 4.0.3 "Ice Cream Sandwich". This does not allow use of Google Play, limiting the number of apps accessible for the Fire HD. Fire HD software updates can be received OTA or from the support websites; the Fire HD 7" second generation used Fire OS 3. Note that although this version is called the Fire HD 7", it is not the successor to the original Fire HD; this model is the successor to the Fire second generation. The Fire HD models second generation were updated to FireOS 4.1.1, based on Android 4.4.4, in Q3 2014.

The Fire HD 6" and 7" third generation uses Fire OS 4 "Sangria", which features profiles so each user on the tablet can have their own settings and apps. The Fire HD 8 and 10 fifth generation uses Fire OS 5 "Bellini" and was released in late 2015. In September 2016, Amazon released virtual assistant Alexa for the sixth generation Fire tablets; the 2018 model of the Fire HD 8 has Fire OS 6 preinstalled, based on Android 7.1 "Nougat". It includes Alexa Hands-Free and the new "Show Mode", in which the tablet acts like an Amazon Echo Show; the 2019 model of the Fire HD 10 has Fire OS 7 preinstalled, based on Android 9 "Pie". *table above only includes data on "HD"-branded tablets Comparison of: Tablet computers E-book readers Official site for Fire Tablets Kindle Fire HD Press Event Article at Ars Technica
