To improve network communications between stores, head offices. Combine all stock databases into a single system on head office server, so staff can view the amount of stock and access most recent up to date data. This would drastically improve the communications between the several stores. To achieve this, all the individual LANS (Local area Network) from the stores must be connected to create a Wide area network, thus this WAN can be accessed through Telecommunications lease lines across the internet. Though for PVMS this type of method is expensive, but will significantly benefit from this change.

Rainbow table: It is a pre computed table for reversing cryptographic hash functions, usually for cracking password hashes. Tables are usually used in recovering a plaintext password up to a certain length consisting of a limited set of characters. Ransaomware: The system that doesn’t allows users to proceed until the payment is done is generally known as Ransaomware. RAT programmes: RAT stands for ¨Remote Administrative Tool¨, it is a malware software, that allows a remote operator to control a system.

1. If there is poor communication in the workplace for example, schedule face-to-face meeting weekly. 2. If there is poor communication with friends, ask them what they do not understand and then broadly explain it again. 3.

Atom are composed of tiny pieces of matter composed of constituent parts A: Protons. Neutrons and Electrons 1. Protons (positive charge) combined to form an atom 2. Neutron (no charge) combined to form an atom 3.

Lone Pairs ADI Lone pairs, the electrons that the central atom does not share during a covalent bond, can and will affect the shape of a molecule in various ways. During this lab, the goal was to answer the guiding question of, “How does the number of lone pairs affect the shape of the molecule?” Answering this question served to cement in those participating in the lab an understanding of the affect a central atom’s number of lone pairs will have on the shape of the molecule, and be able to identify a pattern of molecular shapes and their central atom’s lone pairs. We conducted this lab by first experimenting with 3-D molecular structures on a website, becoming familiar with the geometry of molecules and what exactly lone pairs were.

Plutonium is in the transitional metals section of the periodic table. Plutonium has the atomic number 94 and a molar mass of 244, which implies that it has 94 protons, 94 electrons, and 150 neutrons ("It 's Elemental."). You can tell how many protons and electrons there are by the atomic number of the element since it is the same number. A person can also tell how many

The atomic number of polonium is 84. The average atomic weight is 209. Polonium has 84 protons, 84 electrons, and 125 neutrons.

Other then being an important aspect in humanity Fe, one of the three magnetic elements, the other two being cobalt and nickel, is also the fourth of Earth’s most abundant mineral, by mass (Royal Society of Chemistry, Iron). The source of this iron comes naturally from ores deep in the earth’s crust in sedimentary crusts, since iron oxidizes remarkably fast on the Earth’s surface. For commercial use, pure Iron can transform into steel or an alloy by adding other impurities and elements, making it an

Delocalization of electron density between the filled (bond or lone pair) Lewis type NBOs and empty anti-bonding non-Lewis NBOs calculated by NBO (Natural Bond Orbital) analyzing by B3LYP/3-21G*

Plot the energy values En in the vertical direction for n = 1, 2,3,4,5. Plot the orbital angular momentum quantum number in the horizontal direction for l = 0,1,2,3,4. For each n, show every allowed value of l. Label every energy level spectroscopically (1s, 2s, 2p, ...). Indicate the m degeneracy of each l level. Show that the total degeneracy of each En is n2.

The EB cross section for these compounds is evaluated using Lagrange’s interpolation technique, Seltzer-Berger’s [10] theoretical EB cross section data given for elements and the evaluated results of Zmod using the following expression ------- (3) Where lower case z is the atomic number of the element of known EB cross section z adjacent to the modified atomic number (Zmod) of the compound whose EB cross section is desired and upper case Z are atomic numbers of other elements of known EB cross section adjacent to Zmod. Seltzer-Berger’s [10] theoretical EB cross section data is based on Tseng-Pratt theory[11]. The number of EB photons of energy k when all of the incident electron energy T completely absorbed in thick target is given by Bethe and Heitler [12]

Similarly, carbon dioxide diffuses in the opposite direction. This process of gas exchange is so rapid as to be thought of as instantaneous . Control of

Since Dalton’s atomic theory was created in the early 1800’s people were fixed that this was in fact the correct structure of an atom. Recent discoveries however, have been led to disprove the original theory. In part one, although Dalton originally stated that atoms are indivisible, it is now known that atoms can be divisible due to them being made up of protons, neutrons and electrons. Other experiments by Ernest Rutherford, Hans Geiger and Ernest Marsden show that rather than an atom being a “solid, massy” particle they are in fact mostly made up of empty space. Part two of Dalton’s theory has also had to be modified after it was also proven that atoms of the same element may have different masses due to different isotopes of the same element being able to have varied numbers of neutrons.

Next, there is mass this contains 5 sections in it these are: • challenge
