...Kaitlyn Hainline Biology-4 The Cell Cycle Lab I. Design A. Problem/Research Questions 1. What is the relative time it takes for a cell to go through each phase? B. Variables 1. Independent Variable- The independent variable is the different cell phases (Interphase, Prophase, Anaphase, and Telophase/Cytokinesis). 2. Dependent Variable-The dependent variable is the percentage of cells that are each cell phase. C. Controlled Factors- The magnification is a control factor because I was able to decide what magnification the microscope was on and mine was at (400x). Another control factor was the temperature because it stayed at room temperature throughout the whole experiment. D. Apparatus/Materials Needed * 2 pre stained onion root slides * A microscope at 400x magnification * Calculator * writing utensil * paper E. Procedure 1. Observe every cell in one high-power field of view and determine which phase of the cell cycle the cell is in. 2. Count at least two full fields of view.

Without change, organizations would likely lose competitive edge and fail to meet the needs of what most optimism to be a growing base of loyal customers. In order for an organization to complete a successful change, organization need to able define a change and what specific change is necessary. The next step understands a cycle of change, and compare and contract of the two change agents. Finally is to select, which change agent is best suitable for the change that organization plan to complete. Frist define a change, it is something that presses people out of their comfort zone, it is inevitable, and it is better or for the worst, depending on where, and how people may view it. Change does have a necessary aspect of life and work. The world is changing more rapidly than ever. It is probable that people will have to cope with a variety of changes in the near future. The cycle of change begins when someone sees the challenge, and this challenge can be a threat to people within the organization, but it can also be an opportunity for growth and expansion. Either way, seeing the challenge awakens the need to change. There are...

...will gather more ideas about my topic. Doubtless, I am sure I will make it easier to work with it. One question was bothering me and makes me persevere on doing this Research Paper. “Is it entrainable or not?”, one question with different ideas and information’s sticking with it. No specific and particular reviews I need to provide about it, I just need to gather information by means of researching just to know if Circadian Rhythm is entrainable or not. Although the process is not easy, as people who have suffered from a jetlag, because the more time you did not sleep, the more you will suffer Circadian Rhythm. Sleep and waking, for instance, occur naturally to the beat of an internal pacemaker, which works on a cycle of about twenty-four-hours. My purpose on making and researching is to have broad ideas and I need to answer the question bothering me if it is entrainale or not. I need to defend my title against myself to be proudly to present it and defend it easily.In my title, I used the questioning type because I want to know if Circadian Rhythm is truly entrainable or not.

...OPERATIONS MANAGEMENT EXECUTIVE SHIRT COMPANY CASE Q.1) Compute the following quantities for the current production process as well as for Mike’s and Ike’s plans, assuming the plans are implemented as described in the case. Solution: Current batch processing Sales for the Executive Shirt Company are constituted of only a few basic styles and colours. Hence the company has a limited number of varieties to produce. So, it has large batches of each kind of shirt (size and color). It has only one cutting machine, which is computer-controlled and can cut up to 60 layers of cloth at the same time. Also up to 8 patterns can be cut simultaneously. The cutting process by the machine takes 30 minutes irrespective of the number of patterns and number of layers. But, the set up time is quite significant. It takes 1.5 minutes to roll out a layer of cloth and so for 60 layers; it takes 90 minutes setup time. The machine is being operated by 4 operators and the company is using its maximum capacity, i.e. 60 layers and 8 patterns at a time. So, Total number of shirts cut in one run = 60*8 = 480 Total time taken by one run = setup time + runtime = 90 + 30 = 120 minutes Regular shirts labor content (minutes per shirt) for cutting = 120 / 480 = 0.25 min per shirt Number of workers = 4 |Operation |Regular Shirts Labor Content (minutes |Number of |Time taken per |Time taken...

Average Hourly Demand divided by 24 hours in a day AHD = 1291.29 specimen per day DIVIDED BY 24 hours per day = 53.80 specimen per hour 4. A. Once the specimens arrive at the lab, they are processed. Depending on what kind of specimen test they are undergoing determines which process of the two they will be put through. B. As shown above the all specimens are unwrapped, and then they undergo which ever process they are being tested under. For each of the two processes after the unwrapping they are typed up and then labeled. C. After the process at the LCRA is complete the specimens are delivered to the lab. 5. The bottlenecking occurs in the CRA in the typing processes. It takes a much longer time for the typing process to be complete. With a more efficient typing process this may not be as much of an issue. Also, when specimens are untouched for long periods of time. This is because leaving them untouched for a long time spoils them and then new specimens need to be taken in order to accurately diagnose the patient. 6.

...inventories and low inventory turnover. We have found a way to potentially shrink inventories and decrease plant costs substantially by changing the production cycle times using a well-known production model. Growth in the thick-walled tubing market is also making VBF question its plant capacity requirements. We also address a number of other issues that could help VBF efficiency throughout the plant. Analysis We analyzed VBF production using the economic order quantity model (EOQ) for shared facilities and found a lower cost production cycle schedule that we believe will greatly help VBF to be more responsive to customer needs, reduce inventories and working capital, as well as increase efficiency within the plant. We focus on the EOQ model and its implications for the firm. Exhibit 3A shows the spreadsheet calculations we used to arrive at the shared facility economic order quantity that we are recommending. We compiled costs associated with setting up for products and for carrying the required level of inventory. Setup costs were given as $800 per hour and accounted for the loss in contribution due to changeovers. The cost of carrying inventory was represented as a 24% variable cost. It is given that tubing costs $400 per metric ton; therefore, we use $96 ($400/ton*24%) per ton per year as our carrying cost. The cycle schedule arrived at is just over 38 runs per year given the assumptions of costs and the EOQ model (compare this to the approximately nine runs per year...

...Microbiology in the News Rashaunda McIntyre ITT Technical Institute SC2730 Microbiology in the News Nausea and vomiting are among the most frequently experienced toxic side effects associated with chemotherapy. Chemotherapy is the treatment of disease by the use of chemical substances, especially the treatment of cancer by cytotoxic and other drugs. Chemotherapy is an important part when treating cancer and it is almost impossible for a patient to not experience any type of nausea and vomiting. Chemotherapy induced nausea and vomiting, also known as CINV has 5 syndromes: acute, delayed, anticipatory, breakthrough, and refractory. Acute CINV is known for nausea and vomiting within the first 24 hours after treatment. Delayed is nausea and vomiting that begins after the first 24 hours of treatment and may last for up to 5-7 days. Anticipatory CINV nausea and vomiting often occurs prior to the second or subsequent administration of chemotherapy in patients who have experienced poorly controlled nausea and vomiting during previous courses of chemotherapy. Breakthrough CINV can be defined as nausea and vomiting during any phase of the chemotherapy cycle. Refractory CINV is also described as a failure to respond to prevention and/or intervention during a previous cycle of treatment. Nausea and vomiting affects cancer patients differently. Some are affected physically, some are affected psychologically, and some are affected emotionally. Some anti-nausea...

...Marketing Plan for Cintas and the Healthcare Industry Introduction The purpose of this paper is to describe the business of laundry and the rental uniform plan for the healthcare industry through Cintas Corporation. Product life cycle in the case of Cintas is slightly different. There is not a new product when we are speaking of laundry and the rental uniform. Cintas has been providing this service for a number of years when Doc Farmer started the business known as Acme towels. A product life cycle "describes the stages a really new product idea goes through from beginning to end so for Cintas its finding new customer’s to service that they have not focused on in the past. The product life cycle is divided into four major stages: (1) market introduction, (2) market growth, (3) market maturity, and (4) sales decline. The product life cycle is concerned with new types (or categories) of products in the market, not just what happens to an individual brand." (Perreault, McCarthy, 2010). Market Introduction The 4 P's are used in the introduction stage. The product, laundry service to hospitals, surgical centers and health care providers, is being introduced. During this time branding and quality is established; Cintas has their brand and quality out in the uniform rental market, but they will need to show they can provide a sanitary environment when they also launder for meat processing plants, utility workers, trash companies and pet food producers. Cintas will need...

...organic substances for nutrition. Yeasts require oxygen for aerobic cellular respiration but some are also anaerobic with alternative aerobic methods for producing energy. They do not require light to grow and their temperature range varies which means they can survive in a multitude of different environments. Very common, they can be found anywhere, from occurring on the skins of fruits to residing in the intestinal tracts of animals as parasites. The most common method of reproduction for yeasts is asexual reproduction through budding. In this process, the parent cell’s nucleus splits and forms a daughter nucleus. The daughter cell grows on the parent cell until it is large enough to separate. Through cytokinesis, this ‘bud’ then forms a new cell. Less common is the method of sexual reproduction in which spores are formed. In this lab, I will be culturing four yeast samples under different conditions. The goal is to study the effects of limited reproduction, additional resources (nutrition) and predation on the yeast population. Yeasts play a very important role not only by serving as nutrient recyclers in nature, but by also being important for the food industry because they can convert carbohydrates to carbon dioxide and alcohols through fermentation. They are also used in cell biology research and produce ethanol. 2. When ammonia, which limits reproduction, and a microbe (predation) are added to the culture, the yeast population will decrease. And when additional food is introduced...
