...April Bacigalupi Antanina Walkowiak Report Sheet 1. In molecular series 1, 2, and 3, the intermolecular forces that are present include LDF, dipole-dipole, and hydrogen bonding since all are part of the alcohol group and all contain an OH group. 2. The IMFs that are present in the molecular series 4 include only LDFs because they are part of the alkaline group and are hydrocarbons that contain only carbon(C) and hydrogen (H) single bonds. 3. A. The factor that is affecting IMF strength from one molecule to the next is London Dispersion Forces. B. As we go from methanol→ ethanol→1-propanol→ 1-butanol, the dispersion force increases. C.. As we see on the attached Evaporative Cooling Data chart on Appendix A1, the ∆T increases in the following order, from methanol→ethanol→ 1-propanol, and finally to 1-butanol having the highest ∆T. The strength of IMF is affected by ∆T, thus, the greater the negative ∆T is, the weaker the intermolecular force will be and the less negative ∆T will result in a stronger intermolecular force. D. If we look at the Spartan Data on Table 4 on pg. L119, we can see that the surface area of each molecule is increasing from methanol→ ethanol→ 1-propanol, and finally to 1-butanol. Increasing molecular surface area will increase dispersion forces. Finally, if we go back to Appendix A1, we see that the molar mass is increasing from methanol, to ethanol→ 1-propanol→1-butanol. When the molar mass in a molecule is increased, it leads to an increase...

...best by a given modality (Cherry, 2014). Individuals typically display diverse modes of learning with multiple and varied talents with differing modalities of learning (Kumar, Smriti, Pratap, & Krishnee, 2012). The VAK instrument was expanded by Fleming and Mills in 1992 into the VARK. The original VAK founded in 1970 was original Visual, Aural, and Kinesthetic learning (Bernardes & Hannah, 2009, p. 1-12). The Read-Write method was added to comprise of the VARK and the questionnaire was created with 16 multiple choice questions with four items each corresponding to the four sensory modalities V for visual, A for aural, R for read-write, and K for Kinesthetic (Bernardes & Hannah, 2009). The questionnaire, which is accessible online, is very easy to complete. The VARK instrument can help the student determine their learning style and enable them to apply specific strategies that fit into their preferred learning style and modality. An individual taking the VARK questionnaire with scores of Visual 11, Aural 7, Read-Write 14, and Kinetic 10 would indicate that the preferred or primary method of learning would be the Read-Write method or modality. The Scores of Visual 11 and Kinesthetic of 10 could indicate that the individual could also possibly be a multi-modal learner. A multi-modal learner is someone who uses several different types of modalities to learn and incorporates each one to a specific need or situation to enhance their knowledge. A multi-modal learner would put that individual...

...INTRODUCTION A supernumerary or hyperdontia tooth describes an excess in teeth number which can occur in both primary and permanent dentition. Mesiodens was a term coined by Bolk in 1917 to denote the supernumerary tooth present in the maxillary central incisors. By definition mesiodens refers to a supernumerary tooth/teeth present in the premaxilla placed palatally, labially or in between the two central incisors.[1,2,3] The exact etiology of supernumerary teeth is unknown; however, several theories have been proposed to explain its presence. Out of all the theories only two have been widely accepted. First is the phylogenetic theory as a regression of the anthropoids whose dentition had more teeth and second is the autonomic recessive inheritance or linked to the x chromosome, an abnormal reaction to the local traumatic episode, environmental factors, dichotomy of the tooth germ and the theory of hyperactivity of the dental lamina. [4] Mesiodens can be classified into 2 subclasses, according to...

(ii)A base may be defined as a substance that turn litmus blue. Litmus is a lichen found mainly in West Africa. It changes its colour depending on whether the solution it is in, is basic/alkaline or acidic. It is thus able to identify/show whether another substance is an acid, base or neutral. (iii)An indicator is a substance that shows whether another substance is a base/alkaline,acid or neutral. 2.Common naturally occurring acids include: Name of acid | Occurrence | 1.Citric acid | Found in ripe citrus fruits like passion fruit/oranges/lemon | 2.Tartaric acid | Found in grapes/baking powder/health salts | 3.Lactic acid | Found in sour milk | 4.Ethanoic acid | Found in vinegar | 5.Methanoic acid | Present in ants, bees stings | 6.Carbonic acid | Used in preservation of fizzy drinks like coke, Lemonade, Fanta | 7.Butanoic acid | Present in cheese | 8.Tannic acid | Present in tea | 3.Most commonly used acids found in a school laboratory are not naturally occurring.

They have a basic Microsoft shop that uses a Visual Studio Team Foundation Service to host the image repository as well as Visual Studio to design, QA and develop their site. They are also utilizing Microsoft SQL Server and Microsoft Exchange. Security Vulnerabilities The two Security vulnerabilities that I am going to document are VPN Tunnel potential security breaches as well as SQL Injection attacks. These are the two areas that I believe the organization has not looked at as potential risks for issues. Security Vulnerabilities The first threat that I want to elaborate on is a hardware vulnerability that is inherent in the use of VPN Tunnels. The main threat mostly lies with users not utilizing the same security precautions that are used in the office. Often users are unaware that they have a direct link straight...

Geodesics and Lagrangians ............................................................. 21 ******************************************************************************** I. Basic Principles We shall treat only the basic ideas, which will suffice for much of physics. The objective is to analyze problems in any coordinate system, the variables of which are expressed as qj(xi) or q'j(qi) where xi : Cartesian coordinates, i = 1,2,3, ....N for any dimension N. Often N=3, but in special relativity, N=4, and the results apply in any dimension. Any well-defined set of qj will do. Some explicit requirements will be specified later. An invariant is the same in any system of coordinates. A vector, however, has components which depend upon the system chosen. To determine how the components change (transform) with system, we choose a prototypical vector, a small displacement dx i. (Of course, a vector is a geometrical object which is, in some sense, independent of coordinate system, but since it can be prescribed or quantified only as components in each particular coordinate system, the approach here is the most straightforward.) By the chain rule, dqi = ( ∂qi / ∂xj ) dxj...

...Meghan Marshall 3rd hour It was always so difficult to wake up in the morning for school, but never hard to wake up early on the weekends to step into the brisk air in preparation to show her horse, Cowboy. Amy was an equestrian, and that meant early mornings and late nights were the inevitable. Today was the first morning of the APHA World show in Fort-worth, Texas. Amy Smith never thought that she would compete on the American Paint Horse Circuit due to the level of difficulty but she also knew these were the steps she had to take to be a World Champion. This year was different for Amy and Cowboy, It was their last year of Youth 14-18 before she went on to be a Amateur. Amy knew that after this she could no longer compete with cowboy because Amateur level was too competitive. All the handwork was paying off as her and Cowboy moved to the top of the list in points on the circuit. This morning she knew she had to do good to keep up the points and qualify for the High Point. Amy walked towards the barn and thought about how hard her and Cowboy worked everyday to get where they were. "Amy! Good Morning! Are you ready for today?" Amy's trainer Heather hollered across the isle way of the barn. "I'm very ready, its just a matter of getting Cowboy ready. He seems pretty into his morning hay" Amy smiled while she spoke about cowboy Cowboy was in his blanket munching on his hay. Amy loved him, he was her boy and the best horse she had ever owned. Cowboy was the Hunter Under...
