...Biology REN Stage 1 DeArne Holmes SACE: 976199G Assessment task 4 Issues Investigation: Reproduction: Contraceptive Methods The Pill and Implanon (REFERENCES) Knowing how contraceptive methods work is essential to using them properly and increasing the reliability so pregnancy doesn’t occur. The pill is an orally taken pill which is a combination of the hormones estrogen and progesterone to prevent ovulation (2). You can not get pregnant if you don’t ovulate because there in no egg to be fertilized. The pill also works by thickening the mucus around the cervix, which makes it difficult for the sperm to enter the uterus (2). If you use the pill you need to take it everyday at a certain time to receive optimum reliability because it could leave you unprotected and possibly become...

...3a) Refer to Appendix C of block diagram showing how AM DSB FC demodulation can be performed using a receiving USRP. 3b) Using GNURadio Companion and a transmitting USRP, AM DSB FC modulation can be performed on a message signal with frequency 1 kHz and amplitude of one unit. The following code in Fig. 6 has been used to perform such a modulation with a transmitting USRP. Fig. 6 GNURadio Companion code to perform AM DSB FC modulation on a cosinusoidal message signal using a transmitting USRP. The modulated signal from the transmitting USRP is then received by a second USRP, which demodulates the signal, to obtain a signal whose waveform is comparable to that of the original message signal. Fig. 7 shows the code used on a receiving USRP to...

...• Where has it traveled, and where was it ultimately stored? 6. Why is it important to include a time/date stamp in the security incident response form? Stamping the time and date on the security incident form make it hard to manipulate or modify the file and therefore make it indisputable. It also improves accuracy of the occurrence of activities. It also holds those who come in contact with the evidence accountable. Lab Report File Define the phrase chain of custody. Chain of custody: Documentation that describes how evidence is collected, used, and handled during the duration of the case. Paraphrase what you found for your search of Chain of Custody for Digital Evidence. As I read the link below, I found that maintaining digital evidence is more than just securing the true copy. The perseverance of the hardware is just as important when it comes to maintaining the accuracy of the evidence on the hardware. The durability of the hardware that stores the evidence could become an issue if it alters the evidence over a period of time. It is very important that the longevity of hardware that stores evidence be checked and confirmed to ensure that the true copy...

...Cesium iodide and Alkyl metals salt clusters (Na, K, Rb…. Acetates,), with wide m/e range are commonly used for calibration of mass spectrometers. Polymers as poly ethylene oxide or polypropylene oxide are other excellent calibrators. Dish washing compound lauryl sulfate ethoxylorte, is a good calibrator for the compound for negative ion ESI. Water cluster is another good reference standard, with closely spaced reference peaks the other reference compound used are cesium salt of mono butyl phthalate, perfluyorinated acids, aminomethylphosphonic acid etc. In general a compound is used as a reference, depending upon the calibration required in the lower or higher scale of spectrometer and a with the stable molecular ion with exact m/e value. Nominal Mass. Mass of C12 is taken as 12, is a nominal mass and is a whole number. 1/12 of carbon C12 is 1.nominal mass or µ (a.m.u). In the spectrum it is nominal mass of a sample which is recorded against their relative abundances. Nominal mass for CO2 is 44 and for CH3OH is 32. It is an integer, and is sum of integer masses of elements present in sample compound. Isotopic mass is the exact mass of an isotope of an element, and it is 12 for C12, it is only integer mass. For all other isotopic atoms mass is determined with reference to C12, 1/12 of carbon is µ, is equal to 1.66055x10-27 kg, is taken as standard mass since 1961. Isotopic mass is the mass of that particular atom of an element with reference to C12, 12.000000, For C13; it...

...Discussion: The method by which the mass of a single object was calculated in part 1, is similar in many ways to the method by which the elementary charge was calculated in part 2. Once the relevant data set was either collected or calculated it was first ordered from greatest to least. Next, the first differences between consecutively ordered masses/charges were determined. Thirdly, first differences that were significantly closer to zero than the rest were removed from the data set. Fourthly, first differences that were the multiples of other first differences were removed from the data set. Finally the remaining first differences were averaged in order to determine a mean value for the mass/elementary charge. In order for this method for determining elementary charges to be valid, several traits of elementary charges must be true. Firstly, to determine the elementary charge, it must be true that charge is quantized. This means that the values of charge are discrete, not continuous. If this were not the case, ten this method would not be able to determine the elementary charge because an elementary charge would not exist. Secondly, to determine the elementary charge using this method, the mass and charge of the elementary charge must be constant, and it must maintain this consistency regardless of the temperature, the material that the elementary charges are present in, or any other factor. Finally, all charges, and their composite elementary charges must behave...

...Exercise One Nt1310 Week 1 In: Computers and Technology Exercise One Nt1310 Week 1 NT1310:Week 1 Telecommunications By: Kenneth Martin You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week. 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. b. Central Office In telephone communication in the United States, a central office (CO) is an office in a locality...

But Best Practice dictates to move some of theese Flexible Single Master of Operation (FSMO) roles to seperate servers. If you only have one domain controller (not recommended), there is nothing to do since all roles must be on this server, but if you have multiple servers you should move some of theese roles on to more servers. It is also important to be aware of what servers are Global Catalog servers, especially if you have more than one domain and even if only one domain, they will be prefered by applications like Exchange server. It is recommended to place the forest roles on one Domain Controller (DC) and the domain roles on another server. If not all Domain Controllers are Global Catalog servers, it is also important to place the infrastructure master on a server that is NOT a Global Catalog server.
