...Field exercises 1 In the given figure the organization has got three departments which are orders department, accounting department and payroll department. The activities which play a major role are order filling, invoicing, accounts receivable, inventory control, accounts payable, payroll and general ledger. Given a project manager the responsibilities of the manager would be mainly concerned with orders department which include order filing system which in turn has customer master file, inventory master file and back order file. The manager is responsible for the team work, initiation plan and design, work flow and order delivery. The manager should also maintain a good customer relation, which is not a major key role but also a challenging responsibility. Product delivery, project status, inventory control are the other major challenging responsibilities. The responsibilities which do not come under manager are payroll department, inventory pricing, invoicing system. These are handled by the accounts department and management department, the manager duty is to only handle his team and deliver the project on given time. 2 The steps involved in project planning: Describing the project scope, alternatives and feasibility is the first stage of project planning where the reasonability of the manager is to give a brief idea of the project scope and its feasibility. The second stage is dividing the project into manageable tasks which helps the team members to allot the work among...

...Aaron Mikles 1/6/13 3rd Demiter They say bull riding is the most dangerous sport on dirt. In a lot of ways they are right a lot of people are injured and even killed. In bull riding they say its not if you get hurt its when and how bad. Bull riding has been around for a long time for a few hundred years. Bull riding is an exciting and an adrenaline pumping sport because of the history of bull riding, the way you are scored, and the safety of the rider and the bull. Bull riding has a long rich history, it can be traced back all the way to the early 1800’s. Cowboys would get together and have contests in things they normally do on a ranch like roping and trying to break horses, but you didn’t have to get on the back of a bull for no reason they just wanted to see who could do it and so began bull riding. The first formal rodeo was held in Cheyenne, Wyoming in 1872. Bull riding quickly became the most watched and anticipated event at the rodeos. Cowboys were not organized the first union was called cowboys turtle association (CTA), in 1975 it became rodeo cowboys association (RCA) it later became Professional Rodeo Cowboys Association (PRCA), which is what it is known as today. Before 1992 bull riding was just one of the nine traditional events that took place on the PRCA circuit. In 1992 twenty of the top professional bull riders put up $1,000 each to launch the Professional Bull Riders (PBR) circuit. Bull ridings first widely recognized stat was Dick Griffith...

...Claro Garcia NT1110 CS & L April 9, 2014 Chapter 3 Summary In the world of computers, input/output (I/O) devices are utilized to enhance, configure and control data transfer between the computer and external devices in a variety of ways. These devices use ‘ports’ to connect to either internal or external hardware to and from the computer. The ports are then linked to copper circuits and memory that communicate to the computer CPU, RAM and ports. This enables data transfer between these I/O devices and the computer. Nowadays, the Universal Serial Bus (USB) port is considered to be the most important I/O port among all other I/O ports because it has replaced PS/2 (mini DIN) mouse and keyboard, serial (COM), and parallel (LPT) ports in recent computer systems and providing greater speed. A recent computer desktop system has at least four USB ports and can support up to eight front-and-rear mounted USB ports. The three standard types of USB ports are (1) USB 1.1, (2) USB 2.0 a.k.a Hi-Speed USB -and (3) USB 3.0 a.k.a Superspeed USB and use either Series A a.k.a Type A or Series B a.k.a Type B types of connectors. Adding more USB ports can be done by using motherboard connectors for USB header cables, hubs and add-on cards. Serial (COM) I/O ports also known as RS-232 ports are used for external modems, serial mouse, plotters, label printers, serial printers, PDA docking stations, digital cameras and PC-to-PC connections used by file transfer programs such as DirectCable...

...Chapter 1,2,4 Homework Jake Fischer BUS- 340 Mr. Ryan Kelly Jake Fischer BUS-340 Oct 2, 2013 Ryan Kelly Chapter 1,2,4 Online Research: Common Law Common law, system of law that prevails in England and in countries colonized by England. The name is derived from the medieval theory that the law administered by the king's courts represented the common custom of the realm, as opposed to the custom of local jurisdiction that was applied in local or manorial courts. In its early development common law was largely a product of three English courts—King's Bench, Exchequer, and the Court of Common Pleas—which competed successfully against other courts for jurisdiction and developed a distinctive body of doctrine. The term "common law" is also used to mean the traditional, precedent-based element in the law of any common-law jurisdiction, as opposed to its statutory law or legislation (see statute), and also to signify that part of the legal system that did not develop out of equity, maritime law, or other special branches of practice.

...CHAPTER III METHODOLOGY Research Design The descriptive design of research was used for this study. The descriptive method of research is used to gather information about the present existing condition. The emphasis is on describing rather than on judging or interpreting. The aim of descriptive research is to verify formulated hypotheses that refer to the present situation in order to elucidate it. The descriptive approach is quick and practical in terms of the financial aspect. Moreover, this method allows a flexible approach, thus, when important new issues and questions arise during the duration of the study, further investigation may be conducted. Sampling Design The method of sampling design used in the study is purposive sampling. Purposive sampling is a sampling method in which students are chosen based on purpose of the study. In this method the researcher will attempt to zero in on the target group, the researcher asking or interviewing the students whomever who have teacher parent or relative. After getting the respondents the researcher will have the students answering the questionnaire. The researchers used the questionnaire method for all the students of Benedictine Institute of Learning. Purposive sampling is popular in qualitative research. Purposive sampling does not produce a sample that is representative of a larger population, but it can be exactly what is needed in some cases. The general theme here is that the biggest question any researcher needs...

...add 0.05 M NaOH drop-by-drop to back-titrate the solution until the pH is neutral. What this means is that, the stronger the antacid tablet, the less NaOH it will take to help bring the acid to neutral. (In other words, the stronger antacid tablets counteract more of the original HCl, leaving the solution closer to neutral before the NaOH is added.) Here are your results: Maalox Mass of one dose antacid mL NaOH used in backtitration 20.0 g Tums 21.0 g Mylanta 18.0 g CVS brand 18.3 g Rennies 17.5 g 24.1 mL 22.4 mL 20.0 mL 19.9 mL 24.4 mL 1.

When people do back titrations, they usually watch the solution for a color change when the solution becomes neutral. What might you have used in the above experiment to get this color change to happen in the solution? At what pH would the solution have been neutral? 4. If you had walked into the lab, only to discover that you only had 0.1 M sulfuric acid available to run your tests, how might this have affected your calculations? Why? 5. In...
