This was a reference to the more than fifteen bars on Main Street and their associated rowdiness and gunfights. The town was nicknamed “one Mile of Hell” because it had “a church on each end, with one mile of hell in between”. The hotel was a favorite spot for Sunday diners and a rendezvous for mining, timbering, and railroad men active in the area.

But only during the past 40 years have they come to be viewed as family. For thousands of years, humans have kept animals as pets. These two stories illustrate the drastic change in how animals have been perceived. Afterwards, the hospital’s counselors felt compelled to find the bikers a motel room: their level of grief was so profound that the staff didn’t think it was safe for them to be riding their motorcycles. The dog was intractably ill, and required euthanasia to prevent further suffering. Two decades later, I was working at Colorado State’s veterinary hospital when a group of distraught bikers on Harley-Davidsons pulled up carrying a sick chihuahua. They reasoned that it was cheaper to have a dog euthanized – and buy a new one upon returning – than pay a kennel fee.

Think of friction as a resistance to motion that slows things down.Ĭonsider an air hockey table. Drag opposes and slows the motion of an object through a fluid (see Figure 4.3). Rolling resistance impedes the rolling of a wheel. When the friction prevents the object from sliding, it is called static friction. Kinetic friction is a force by a surface parallel to the surface that opposes the motion of a sliding object and causes it to slow down. We further identify different types of friction. ![]() Generally, friction is an external force that acts opposite to the direction of relative motion or to prevent slipping. What force acts on the box to slow it down? This force is called friction. ![]() Without this net external force, the box would continue to slide at a constant velocity (as stated in Newton’s first law of motion). The key to understanding why, for example, a sliding box slows down (seemingly on its own) is to first understand that a net external force acts on the box to make the box slow down. You have probably noticed that a moving object will usually slow down and stop unless some effort is made to keep it moving. (Recall that constant velocity means that the body moves in a straight line and at a constant speed.)Īt first glance, this law may seem to contradict your everyday experience. A body in motion tends to remain in motion at a constant velocity unless acted on by a net external force.A body at rest tends to remain at rest.Newton’s first law of motion states the following: Emphasize the direction of the force of friction. Ask students to give different examples of systems where multiple forces occur.

The frame is durable the ComfortMAX seat lets you sit for hours in total comfort, and the seat’s 360-degree silent swivel allows you to take full advantage of your hunt area. If your primary goal is to bow hunt from this tripod, I recommend adding the extension. The four-foot extension is handy for those areas where cover is sparse, and the hunter wants to gain extra elevation. The 10-foot height is perfect for backing the stand into the brush so the hunter can disappear in a vegetated backdrop. The total stand weight is 36 pounds, and the setup time, if you read the owner’s manual, is less than a minute.

My intuition strongly suggests to me that $value should go out of scope after the first foreach loop, but apparently my intuition is wrong. It is recommended to destroy it by unset().” As the PHP documentation states, “Reference of a $value and the last array element remain even after the foreach loop. The reason is that the first foreach loop passes values by reference ( &$value) while the second passes them by value ( $value). ![]() Okay, so it’s not really inexplicable, just very unexpected. Yes, that’s right, the final key inexplicably appears to have the same value as the previous key, despite print_r suggesting otherwise. If you also expected that, you would be wrong. Now, call me crazy, but I expect both the print_r call and the second foreach loop to return pretty much the same information: the keys, a to f, and their corresponding values, 1 to 6. Consider this slightly contrived example code: I just spent a couple of hours debugging something really counterintuitive, where PHP’s print_r seemingly told me that an array had different content to the content that the same array contained according to a foreach loop. You can also use the arraysplice() method to remove. * string $fields The names of the keys or properties to remove.įunction deep_unset_all( array|object &$data. The short answer is to use the unset() function of PHP that takes array variable with key as an argument. You can not unset a numeric key of an array, if key is a string. * Unsets all array keys and object properties of the given names. This function lets you specify a variable number of fields to remove altogether! /** Deep Unset Multiple FieldsĪdditionally, you may want to recursively unset multiple fields at once. * string $prop The name of the property to remove.įunction deep_unset_prop( array|object &$data, string $prop ) Example Usage deep_unset( $employees, 'id' ) // Remove all "id" properties and keys. * array|object $data An iterable object or array to modify. * Unsets object properties of the given name. Use this function when you want to only unset a specific property in every object instance. This means the following functions may be safely called without preliminary deep checks. Note that PHP’s unset() function doesn’t throw an error or warning when given non-existent fields. Unsetting array values in a foreach loop duplicate Ask Question Asked 13 years, 4 months ago Modified 2 years, 3 months ago Viewed 152k times 77 This question already has answers here: How do you remove an array element in a foreach loop (7 answers) Closed 6 years ago. After going through the first foreach loop, array remains unchanged but, as explained above, value is left as a dangling reference to the last element in. This makes the functions much more efficient! By passing a variable by reference, the function makes direct modifications to that variable’s value rather than returning a modified copy. ![]() This is how to pass variables by reference in PHP. Notice that an ampersand (&) precedes the first parameter in each of the following functions. ![]() To cover all cases, I’ve written the four different functions (plus a bonus, fifth function) that you need to recursively unset data fields. Sometimes SDKs will parse data into objects while other SDKs will return data as associative arrays. Now, there are two different ways to represent maps (key-value pairs) in PHP: objects and arrays. That’s why I wrote some functions to recursively unset fields in my multi-dimensional datasets! Since the frontend didn’t need these IDs, I wanted to strip them before passing the dataset back to the frontend. This function also returns the removed element of the array and returns. The server-side requests to the API return nested records, each with their own resource IDs. To remove the first element or value from an array, arrayshift() function is used. Recently, I implemented a frontend UX that asynchronously loads data from an API. ![]() ![]() ![]() To the best of the authors’ knowledge, this study is the first of its kind in the region to study the pattern of troponin testing in the ED of a large tertiary care centre. A Mann-Whitney test was used to compare associations with LOS.Įthical approval for this study was obtained from the Medical Ethics & Research Committee of the College of Medicine & Health Sciences, Sultan Qaboos University (MREC #1122). A Chi-squared test was used to compare categorical variables between groups and a t-test was used to compare mean ages. Means and standard deviations were used to describe continuous normally distributed variables, while non-normally distributed variables were described as medians and interquartile ranges. All categorical variables were presented as frequencies and percentages. A P value of <0.050 was considered statistically significant. 7 The final diagnosis of each patient was categorised as either cardiac or non-cardiac, with cardiac diagnoses including heart failure, an ACS, atrial fibrillation or other forms of arrhythmia.Īll statistical analyses were performed using the Statistical Package for the Social Science (SPSS), Version 21.0 (IBM Corp., Armonk, New York, USA). Epigastric pain was included as a cardiac symptom as it is potentially indicative of an atypical presentation of angina furthermore, it is often difficult to distinguish between epigastric and retrosternal discomfort. The presenting complaints of the patients were classified as either cardiac or non-cardiac, with presenting cardiac complaints including chest pain, palpitations, breathlessness and epigastric pain. Troponin levels were considered positive at ≥0.04 μg/mL and negative at <0.04 μg/mL, as per the reference levels recommended by the manufacturer of the assay kit (AccuTnl+3 Reagent Kit, Beckman Coulter Inc., Brea, California, USA). Patient data were obtained from the hospital’s electronic records. The month of July was chosen at random for the study period. Patients who presented with a ST-elevation MI (STEMI) were excluded. This retrospective study included all adult patients ≥18 years old undergoing cTn-I testing following their admission to the ED of SQUH during July 2015. 5, 6 This study therefore aimed to review patterns of troponin testing among patients attending the ED of the Sultan Qaboos University Hospital (SQUH) in Muscat, Oman, and to examine whether initial troponin test results had an effect on patient management, especially length of hospital stay (LOS). 4 As the main reason for testing cardiac troponin is to rule out an acute coronary syndrome (ACS), it is thus essential that troponin is only checked in circumstances where the probability of ischaemic heart disease is high and an ACS is suspected, especially as indiscriminate troponin testing can lead to unnecessary investigations or a misdiagnosis. However, because the troponin test is very sensitive, an inevitable number of false-positive results is to be expected. Of these, the most widely used and extensively validated biomarkers for detecting cardiac cellular injury are cardiac troponins T and I (cTn-I) as they have a high sensitivity to and specificity for myocardial damage. Necessary diagnostic investigations include a thorough patient history and physical examination, chest X-rays, 12-lead electrocardiography (ECG) and blood tests for myocardial injury biomarkers. 1 As there are many causes of chest pain, the emergency physician has the responsibility of ruling out potentially life-threatening and serious conditions, such as a myocardial infarction (MI), aortic dissection or pulmonary embolism. Accordingly, a thoroughly clinical evaluation should be conducted prior to a test request.Ĭhest pain is one of the most common reasons for emergency department (ED) attendance. The findings of this study highlight the need for protocols to guide troponin testing as, unless indicated, it can lead to unnecessary investigations and delayed patient discharge. ![]() |
