Read on for three tips to balance evening nursing classes with everything else you have going on in your life. Home health care is an exciting field to be involved in but is it right for you? We seem to get this question a lot. Whether you want to become a nursing leader, get involved with training or move into a management position, becoming a BSN can help. An online program may offer significant benefits.

The registered nurisng degree program has become the ideal way for the registered nurse RN seeking their Bachelor of Science in Nursing BSN degree, to further their career in the dynamic and exciting world of health and modern medicine. Men and women with a registered nursing degree are not in the same arena as workers who face potential job loss or layoffs every day. A registered nursing degree provides career education in an area that is consistently growing and thriving — healthcare.

Choosing a registered nursing degree over a licensed practical nursing LPN [ Get a personal calendar. Or start using the one on your phone. However you decide to calendar evening nursing school activities, you will be glad you did. Track all classes, projects, test dates, deadlines, internship hours, and any other work and school activities. Once everything is written down, you can clearly see where your time is spent, and be able to create a plan that helps you spend your time efficiently.

Nursing school can be stressful, work can be stressful, but I can promise you that proactive and organized calendars drastically reduce that stress. So you will have to make the most out of each one. In addition, withlinks instead of wires , the system weightwill be lowered. In this paper, thesensors and electric resistance wires.

Previous reports showed that the level of injury is usually located at or near the C5 segmental spinal level, and the term midcervical quadriplegia has been posed of a diode, a regulating circuit made up of a time-base circuit and an adjustable resistance , a temperature sensorconnected with a heating wire by a thyristor.

August 23, at 7: Again, I will record the voltmeter and ammeter readings and turn off the power pack. I will repeat this method every 5cm until I get up to cm, taking three readings from both the voltmeter and ammeter each time to ensure accuracy. To ensure accuracy I will record the voltage and the current three times every 5cm and take the average reading. This will reduce the chance of false readings and will cancel out any anomalous results.

I will also ensure that the wire does not heat up too much by confirming that I do not set the voltage too high on the power pack and by maintaining the same the voltage for every reading. In addition, I will make sure I turn the power pack off after each reading. I will try to make this investigation as accurate as possible. There are different variables that can be changed in this experiment; these are the independent variable. However, due to my line of enquiry, I will only change the length of the wire.

The variables I will control will be the type of wire resistivity and the cross-sectional area of the wire. I will also control, using the power pack, how many volts pass through the wire. Below is a table illustrating the effect of changing the variables see Table I will ensure experimental safety by confirming that all the wires are connected properly and that none of the insulation on the wires is worn.

I will also ensure that there is a clear indication that the power is isolated by means of a switch and an L. I will stand up during the investigation to ensure that I do not injure myself if something breaks. Below is a table of my results Table 3. I have taken three reading and have worked out the average, shown in red.

Table 3 shows that as the length of the wire increases, the resistance increases, as well. This confirms the first part of my prediction: In addition, my prediction that doubling the length of the wire increases the resistance by a factor of two is correct see Table 4. Graphing these results shows a nearly straight line, illustrating a strong positive correlation between length and resistance, which is consistent with my prediction. Overall, my results are very consistent with my predictions.

Most of the data points were on, or very close to, the line of best fit. There are a few data points that are farther away from the line of best fit than the others, but they are still consistent with the general trend. There are no anomalous results that I would consider to be far away from the line of best fit.

There are possible sources of error that might have led to inconsistent results, such as a kink in the wire. This would have prevented the area of the wire from remaining constant and would have affected my results.

However, I made sure that the wire remained straight throughout the experiment. I think that the range of my results was sufficient enough for me to draw a valid conclusion about how the length of the wire affected the resistance. This was because I could plot a graph and show the general trend.

However, I think that unless I had specialist equipment the results would be distorted because the wire would eventually get very hot.

Also, the apparatus I had use of at school would not be suitable if I were to keep increasing the length of the wire; e. I think my method could have been improved to produce results that were even more consistent. I could have considered using a new piece of wire each time in order to regulate the temperature more stringently. Using the same piece of wire throughout the experiment meant its temperature rose slightly over time, which may have affected my results.

However, using new pieces of wire each time would have been too impractical and time-consuming in the context of this lesson. Overall, I think my method was sufficient to obtain reliable results. To support my prediction and conclusion, I could do further experiments. For example, I could use different types of wire instead of using only nichrome.

I could also consider using different cross-sectional areas of wires or even change the temperature of the wires deliberately and see how manipulating these variables affect the resistance of the wire.
