...distinct layers: 1. The epidermis connective tissue 2. Dermis connective tissue Beneath the 2nd layer is loose connective/adipose tissue called hypodermis epidermis The epidermis has five layers: 1. Stratum Germinativum (deepest) 2. Stratum Spinosum 3. Stratum Granulosum 4. Stratum Lucidum 5. Stratum Corneum (most superficial) The two deepest layers are called the Germinative Zone or Basal Zone The other layers are called the Horny Zone Epithelial cells in the skin undergo a process called keratinisation, which means the cytoplasm is replaced with keratin. Keratin contains nitrogen, amino acids and varying propotions of sulphur. Hard Keratin contains 4-5 % and is found in nails and hair. Soft Keratin contains 2 % and is found in skin. Cells found in epidermis are 1. Epithelial cells 2. Melanocytes Features of: Stratum germinativum: consists of a single layer of columnar shaped cells with nuclei. These cells have tiny processes on their lower surfaces, which seem to anchor them to the underlying dermis. Stratum spinosom is several layers thick, and is composed of irregular cells, slightly separated from each other. There are intercellular bridges between these cells, which appear as spiny processes. Stratum granulosum is a layer consisting of three or five rows of flattened cells,lying parallel to the skin surface, Stratum lucidum is a clear, translucent layer of three or five...

...a useful tool for learning about networks. The OSI Reference Model is where the communication system (network) is broken down into seven layers, where each layer serves a purpose. The OSI Reference Model defines what each layer’s function is but does not specify actual services in the layers. So that the vendors can write device drivers for a device; and not be concerned about the higher layers, this speeds up the process. The seven layers are divided into three groups: 1) Application (upper) layer, 2) Intermediate layer, 3) and Network oriented (lower) layer. With this system the OSI Reference Model is convenient because you’re able to communicate with a different computer network. The WAN Network operates on the Physical and data link layer of the OSI Reference Model. What are some Protocols? The purpose of the OSI Reference Model is to determine how data should be transmitted between two points in a network. Its job is to consistently work with other products. On which layer do switches and routers operate? Layer two, three, and four the Presentation layer, Session, and Transport Layer is where the witches and routers will operate. If Routers operate on more than one layer, what is the difference? Routers operate on layer three then apply on layer two and the switch the packets. Layer two would be Ethernet and layer three is the operating systems...

...acid than in base, elemental chlorine is presumably the oxidant, and hypochlorous acid must be present. It may form an intermediate alkyl hypochlorite ester, which by an E2 elimination gives the ketone and chloride ion. The purpose of this experiment is to oxidize an alcohol to a ketone with household bleach. The product is isolated by steam distillation and is extracted into the distillate with ether that is dried in a column of drying agents. Removal of the ether leaves the product cychohexanone. Theory Cyclohexanone is used as a precursor for nylon. This makes it one of the largest mass produced chemicals in the industry. Billions of kilograms of cyclohexanone are produced each year for the making of nylon. The synthesis of cyclohexanone is simple. First, sodium hypochlorite and acetic acid are reacted to yield hypochlorous acid. Second, hypochlorous acid is added to cyclohexanol to synthesize cyclohexanone. After cyclohexanone is synthesized, it must be separated out from by-products. In order for it to be separated out, sodium chloride is added to the mixture. The sodium chloride will salt out the cyclohexanone from the aqueous layer. Now the aqueous layer and the cyclohexanone must be separated. Dichloromethane is added to the mixture. Next, the cyclohexanone and dichloromethane are separated from the...

Students should also be advised about the online resources that are available to supplement the text. The resources for Instructors are also helpful. The PowerPoint presentation and Web resources can be easily incorporated into class. The testbank is also valuable. War Stories Microsoft Internet Explorer and HTML Standards (Objective: illustrate the importance of standards) In early 1996, when we were developing our Web-groupware software (now a commercial product called Consensus @nyWARE (www.softbicycle.com)) we discovered that Microsoft’s IE would not work with our software. IE did not support the full HTML 3.0 standard in forms processing. All the form information was returned in reverse order from the standard. Since IE was a marginal product at the time and since our project was a research project, we decided not to bother rewriting our software to support IE. I received an email message from an IE user mentioning that they had discovered that IE would not work with our software and asking if we knew why. I didn’t really read the note very carefully. I explained the problem and told them they should use...

...our network. Devices are shown for reference on the bottom row. The next row up is our Access layer, we can see that we are hoping to utilize eight switches for this network, all with at least one route that has logical bandwidth aggregation for backup and redundancy. In the second layer of switches we have our distribution layer, made up of 5 switches, also with physical and logical redundancies. In the very top layer we have our core layer, made up of three switches. (Network Topology of Visio Document Attached to lab also.) Network Segmentation Our network segmentation will be handled via VLAN (Virtual Local Area networks) that we will manage in future design requirements. This should handle our properly segmenting our cameras from our different departments/workgroups. (Printers, Servers, Users, etc.). Network Size and Scope Devry is looking to setup a network that can handle 150 cameras and provide connectivity for 120 existing users, printers, and servers, with 20% expansion. With that, we took into assumption that that would mean 150 cameras would be connected immediately, with the ability to handle another 30 in the future, totaling 180 cameras. Then we would need to handle 120 existing devices with enough to handle an additional 24 for future expansion. Our Total network will need to handle 324 devices. Our Infrastructure Support Access Layer: When looking at our 324 devices, we could see that we may be able to accommodate this many...

...a reaction to completion because the starting reagent has a slow reaction time. The purpose of reflux is to increase the reaction rate by boiling, but not to vaporize the products due to the low boiling points. The mixture of the starting material were heated first under reflux by increasing the rate of reaction through heating with a condenser attached because the temperature can be controlled while the condenser preserves the reagent by chilling the vapors. At the end of reflux, the mixture contained the products of each starting material. The mixture goes through reflux first because simple distillation does not allow enough time for the reaction to reach completion before separation. The solution goes through simple distillation after reflux to separate the products using the boiling points. For 1-propanol, the boiling point is around 97°C. Boiling point for 1-propanol is higher than the product produced, 1-bromopropane, which boils at around 72°C. The distillate should form around 72°C and should drop into the receiver at around 116°C, which creates the desired product of 1-bromopropane. The temperature range of...

...DATA WAREHOUSE ARCHITECTURE Albina Yusupova Data Warehouse Architecture The main difference between the database architecture in a standard, on-line transaction processing oriented system (usually ERP or CRM system) and a Data Warehouse is that the system’s relational model is usually de-normalized into dimension and fact tables which are typical to a data warehouse database design. The differences in the database architectures are caused by different purposes of their existence. In a typical OLTP system the database performance is crucial, as end-user interface responsiveness is one of the most important factors determining usefulness of the application. That kind of a database needs to handle inserting thousands of new records every hour. To achieve this usually the database is optimized for speed of Inserts, Updates and Deletes and for holding as few records as possible. So from a technical point of view most of the SQL queries issued will be INSERT, UPDATE and DELETE. Opposite to OLTP systems, a Data Warehouse is a system that should give response to almost any question regarding company performance measure. Usually the information delivered from a data warehouse is used by people who are in charge of making decisions. So the information should be accessible quickly and easily but it doesn't need to be the most recent possible and in the lowest detail level. Usually the data warehouses are refreshed on a daily basis (very...

...equilibrium equation of the iodine species is as follows: I2+I_=I3- (1) The equilibrium constant is calculated as: KC=(I3-)I2I- (2) Where the equilibrium constant KC is calculated from the concentrations of the species and does not take into consideration the activities of the species. Knowing Kc will indicate if the reaction favors products (if Kc>1) or if it favors products (Kc<1). Sodium thiosulfate is used to determine the concentration of Iodine in solution via titration in the following reaction: 2S2O32-+ I3- → S4O62-+ 3I- Before titration excess KI is added to each solution to ensure that I2 is converted completely to I3-. This is done to ensure that molecular iodine is not loss to evaporation while in the aqueous phase (I3- is non-volatile). However, this method only exposes the total amount of iodine dissolved in the aqueous solution and not the concentrations of individual species. That determination can be aided by examination of the heterogeneous equilibrium existing between the aqueous layer and an organic layer comprised of dichloromethane. The distribution of molecular iodine between the two immiscible layers can be related by a...

...making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object. How does 3D printing work? It all starts with making a virtual design of the object you want to create. This virtual design is made in a CAD (Computer Aided Design) file using a 3D modeling program (for the creation of a totally new object) or with the use of a 3D scanner (to copy an existing object). A 3D scanner makes a 3D digital copy of an object. 3d scanners use different technologies to generate a 3d model such as time-of-flight, structured / modulated light, volumetric scanning and many more. Recently, many IT companies like Microsoft and Google enabled their hardware to perform 3d scanning, a great example is Microsoft’s Kinect. This is a clear sign that future hand-held devices like smartphones will have integrated 3d scanners. Digitizing real objects into 3d models will become as easy as taking a picture. Prices of 3d scanners range from very expensive professional industrial devices to 30 USD DIY devices anyone can make at home. Processes and technologies Not all 3D printers use the same technology. There are several ways to print and all those available are additive, differing mainly in the way layers are build...

...is on the rise is three dimensional printing. Three dimensional printers are machines that can take a shapefile or design created in a computer-aided design software, CAD, and produce the custom designed image into a working test product. Three dimensional printing has taken manufacturing to a new level due to the ease of producing prototypes. Companies have harnessed this technology and used it to produce actual size prototypes that can be physically held and interpreted before producing. These prototypes can also benefit by being a “dummy” for creating injection molds. Indeed this technological advance is a great hype and improvement in the world of production saving time and money in the long run; however, the question is raised, can this epidemic be harnessed by everyday users in their home? There are both pros and cons to the use of three dimensional printers that need to be addressed before the decision can be made of whether this advancement is sensible or not. Nick Allen from Gizmodo.com is very strong on his article expressing the cons to the issue. On the other hand, Christopher Barnatt, from his website Explainingthefuture.com, takes more of a liberal stand to the issue at hand. Three dimensional printer pose numerous negative effects to the world. While this technology may seem cool, new, and intuitive, the idea of owning such printer at home may actually be a far cry from reality. The printers with the capability of printing in three dimensions use a mass...

...the placement of the products going to influence their price? Minjun Yu ECON 4980 Introduction In today’s commodity economy, it is no longer only about manufacturing, transportation, cost, profit, supply, demand, etc. There are many other factors that matters in the sales of the commodity. For many years, retailers have been searching for methods to help them identify ways to improve their merchandise presentation (Ron Larson).One of the methods that retailers used to improve the sales is the display of the products in the aisles. Bezawada has said in his reach that “retailers can benefit substantially by having better placement of items in their aisles,” (Ram Bezawada). Bezawada’s research shows that aisle placements can influence sales across product categories as much as other marketing variables, such as price or how an item is displayed (Jacqueline Ghosen, 2009). According to some researches, changing the allocation of the products will increase the weekly sales by more than 9% (Jacqueline Ghosen, 2009). From all these research, we can see that products placement is one of the most important factor that going to influence retailer’s profits. Putting products in the right place will bring more benefits. In marketing field, there are also some important theories about placement of products. It is called marketing mix which is usually refers to E. Jerome McCarthy's 4P classification for developing an effective marketing strategy. It encompasses product, price, placement...
