Laboratory Techniques and Measurements Lab 1 (Labpaq) free essay sample

Throughout lab one we were introduced to many different forms of measurement, whether its using a ruler too measure length, a digital scale to measure weight, and also many different sized and shaped flasks to measure different volumes. Another key measurement of this lab was to teach the student about density and how to measure it. Density tells us that it is defined as the mass per unit measure, in which as we know is most oven referred to as volume and is also used to describe how heavy something is. We were also required to calculate many different measurements do to the number of moles that one substance might have due to the amount of material/solution we are currently working with. Along with all the measurements and how to use them correctly that Lab 1 teaches us, it also presents to use how to record our data correctly using Significant Figures. We will write a custom essay sample on Laboratory Techniques and Measurements Lab 1 (Labpaq) or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Significant figures are the number of digits that we may use including or excluding the zeros that we may be given with any number or solution. There are many different rules in determining the proper number of significant figure in an answer. For example; â€Å"All zeros to the right of the decimal place and to the right of a non zero digit are consider significant†. So we were given the number 45. 000, we know from the rule above that this figure has 5 significant figures because the zeros following he unit are behind the decimal place and are considered significant. My Hypothesis for this lab was simple, can I or can I not make the proper measurements using the provided materials and measuring devices included for this lab. Along with making the appropriate measurements, will I be able to use the rules I was taught and record my data with the correct significant figures? This lab is all about measurements and recording them properly. The lab first introduces to use the measurement of centimeters, millimeters, and meters to measure different household objects in our everyday life. We were given the task to use the provided ruler and measure a CD, key, spoon, and a fork in centimeters and then convert our findings to give us the appropriate units of millimeters and meters for each object required in the exercise. Data Table 1: Length measurements. | Object| Length (cm)| Length (mm)| Length (m)| CD or DVD| 12cm| 120mm| . .12m| Key| 5. 5cm| 55mm| 0. 055m| Spoon| 15cm | 150mm| . 15m| Fork| 18cm| 180mm| . 18m| Lab 1 also teaches us the importance of molecular weight of a substance and how to use that to find the amount of moles of that substance in a solution. For example; in exercise 3 we were asked to weigh 8 grams of sugar and then calculate how many moles of sugar it really was. Using the molecular weight of sugar (C = 12. 01 grams/mol, H = 1. 008 grams/mole, O = 15. 00 grams/mole). We were then able to use this molecular mass of the sugar that we then had to use to calculate and determine the molarity of the sugar solution that we were working on for exercise three. Data Table 8: Initial Concentration. | Chemical| Mass(g)| Molecular Weight (g)| Moles in Volumetric Flask| Total Volume (L)| Molarity(mol/L)| Sugar(C12H22O11)| 8. g8. | 28. 018g| 0. 29 | . 0025L| 116 mol/L| My analyses of this lab is like so. The lab presented itself with great learning options for teaching us how to use and proper measure the different units of the Si system, but as easy as they are to learn there are many of possible solutions for error. Since this was the first lab the many of the students have probably done in a couple years, I see plenty of room for h uman error do to the lack of training or experience with most of the lab equipment required to compete this lab to the full. Not only is there room for human error but there are also the possibilities of error with the lab equipment whether it is the student’s fault or just default equipment. For example, if the digital scale, required for most of the lab, is not tarred right, your numbers from your experiment are going to be way off. One wrong calculation or measurement could ruin a whole exercise if not whole entire lab itself. In my conclusion for this lab was pretty accurate to my hypothesis. I was able to make most of the appropriate measurements with little to no error at all. I had trouble with the density at first seeing I have never used the method for calculating density. After a few tries I was able to succeed in calculating all the appropriate calculation required for this lab as well as using the appropriate significant figures for all my answers in my lab right up. Measurements are all around us in our daily life. We use some sort of measurement on a daily bases whether we know it or not. Without measurement or the SI units we would have no since of idea of how much something may way or weather or not the water was going to fit into a single are or space (density). The unit of measure is used so much throughout the world everyday that without it, the world would have no since of weight, mass, height, width, or any other unit from the Si family. We use this form of description for almost everything living and non-living in our world today.

Dental Office Network Systems Case Study Example | Topics and Well Written Essays - 750 words

Dental Office Network Systems - Case Study Example Despite the robustness of the proposed network, the report will details its risks along with its benefits. Network Requirements The entire organization, which has five offices, must connect to a central repository where all data will be stored. Because of this reason, proposed network must have a server to store all files for the five offices. In addition, the need for a fast and reliable network calls for a fast network connection that supports high throughput such as T1 lines. In the new organization, four dentists are mobile, which calls for a provision of remote connectivity such as VPN along with switching services using routers and layer three switches. With the network responsible for securing patient’s data as per HIPPA laws, the network must allow data encryption and authentication of users who access the network. Safety of Information Safety of patient’s data is an paramount goal the proposed network must address effectively. Since the organization will be dea ling with crucial information about patients, all information about patients including admission and treatment records be safe and secure. This will be possible if the files server will encrypt data using encryption such as EAS. Moreover, the network must protect data during transmission using encryption techniques and technologies such as VPN. Among the five offices, the network must allow senders and recipients of data to authenticate before transmission of data. The VPN technologies will mobile workers to connect to the central file server securely without compromising on safety of data (Baldauf & Stair, 2011). The network must also have a firewall and intrusion detection system to prevent any unauthorized access to the organization’s data. Users will also need to authenticate their devices before using the network especially wireless access points due to security concerns. Network Type, Components, Devices, and Equipment for the Network A metropolitan network (MAN) system is the best network type that will match the requirement of the new organization. A MAN network has the capacity to span several cities and capable of delivering high bandwidth connections using existing telecommunication lines (Morley & Parker, 2009). The proposed network will have several components to link the five offices and the remote workers. Consequently, the proposed network will have five routers connected with serial cables in a mesh topology. These routers connect to layer three switches to enable packet switching and separation of departments using VLANS. The switches must have at least enough number of ports and support security protocols such as IPSEC. For remote workers, each will have a laptop and a VPN enabled dongle that will allow them establish a secure connection to the central database. With security being a vital issue, devices such as firewalls and backups devices must be located within the network to improve security and recovery process. Most important, t he network must have a network server that will store all data and identifiable using a static IP address and a secondary backup in the cloud to provide continuity during an outage. The servers must have power backup and standby power generators not to mention hot swap features to avoid taking the server offline during service.

Research Article Analysis - Essay Example The narrators would give a precise description of a child/ children with SLCN and give their concerns on the same. The researchers aimed at resolving a question about the knowledge and understanding of the professionals in their early years of developing children’s language and speech. The correspondents were chosen according to their confidence levels, quality of training, the need for further training and their employment of strategies to assess for SLCN (Mroz & Hall, 2003, 126). These led to a selection criteria in which the interview sample were chosen. It includes the type of setting, the level of confidence, and the role /job title of the correspondent and the regional authority of the respondent. Questions were then shared with the interviewee prior to the interviews that were audio-taped. The question was structured in a manner that it had a focus on a single child and least interference from the interviewer. The study used a research methodology for developing a theory that is grounded in data collection and analysis (Strauss & Corbin, 1990, 10). Analysis of data obtained from the fifty interviews was done using the Non-numerical Unstructured Data Indexing, Research and Theorizing (NUD*IST) software (Richards and Richards, 1993, 2). This software allows the user to store and classify data and then search for patterns quickly and in an efficient manner. Coding of transcripts was done to ensure coherence and consistency of patterns in responses obtained from the interviewees. The results obtained indicated that practitioners with medium confidence levels were less likely to volunteer for the interview compared to those with high confidence levels. According to Mroz and Letts (2008, 86), such occurrences is owed to the fact the people with little faith feel in need of help and information compared to those with high confidence who believe

Communication Skills Test Report (Testyourself.psychtests.com, 2013) The report displays strengths, potential strengths, and limitations. As a C/S type personality, I tend to be passive in my approaches to people. According to Carbonell, â€Å"you are one the most passive types, but you tend to be reserved in the ways others like† (Carbonell, 2008, p. 77). This passive approach reveals my passion to help people on a personal level. (Uniquely You, 2013) Who is the â€Å"Me I See†? The â€Å"Me I See† has a C/S personality type. Passive by nature, I tend to give an impression of being disinterested in people or their issues. One of my motivating factors is being sure of other’s expectations before proceeding (Axiomsoftware.com, 2013). I see me as a person who has solid strengths but noticeable weaknesses as well. I am precise when it comes to details and facts. However, if not presented with a question, I tend to withhold my opinions until asked. This speaks of my hesitancy to take any risks. I do tend to remain to myself and not be as outgoing as possible. Thinking more positively and not being afraid of failure can beneficial in  controlling my behavioral tendencies (Uniquely You, 2013) As I review my 360 Interview Survey Results from individuals that know me, both seem to express similar concerns. I am looked at as a person who procrastinates at times, taking time to feel out and get comfortable in situations. With these patterns, it is wise for me to come out of my comfort zone and be more decisive (Carbonell, 2008). I value support, stability, and accuracy. I rely on data before making decisions and more than likely, take an objective approach (Resources Unlimited, 2013). These attributes describe the â€Å"rocking the boat† mentality. No one desires to be the person who rocks the boat or causes it to sink. My personality profile depicts this kind of mentality. According to Peterson, â€Å"when flat-brained, we say crazy things that seem reasonable to us at the time† (Petersen, 2007, p. 26). As a C/S Type Personality, my firm and strong personality can at times become damaging. One way to counter the flat-brain syndrome is to have goals that reduce emotional disturbance, clarify thinking, increase self-confidence, and build supportive friendships (Petersen, 2007). Thinking clearly can help me see different options and make decisive decisions. Hallmark Purpose I am committed to having the mindset Christ had toward His Father, seeking to glorify God in every area of my life. God did not intend for me to be passive and non-decisive in life. I am an overcomer and will conquer my fears. For whoever wants to save his life will lose it, but whoever loses his life for me will find it. (Matthew 16:25, King James Version). My desire in life is to work full time in ministry. I seek to serve God and others. My rationale for having the mindset of Christ is to simply reflect and embrace the true Christian lifestyle. â€Å"Me I Want To See†. The person I want to see in me is transforming from a passive person to a purpose driven person. I do not desire to just simply get by in life in my relationships with others. Hesitancy is not productive. The courses in PAC500 are challenging me personally. Developing superior listening skills and solving the people puzzle is not just for my counselees. I am beginning to look at myself now before even considering anyone’s problems. My purpose lies in  developing the whole man, inside and out. This first begins at home and spread abroad. My hallmark is now a solid foundation to build upon. I am currently looked upon as helpful and considerate. I have a servant mentality. The â€Å"me I want to see†, is adding the qualities of boldness and decisiveness in the continual process of developing the whole man. References Axiomsoftware.com. 1994.
