impermeable to water. Then, water can move out of the collecting duct and be reabsorbed into the interstitial fluids. ADH secretion is regulated by both osmoreceptors in the hypothalamus and atrial stretch receptors, invoking a negative feedback loop to control osmolarity of the blood plasma as well as vascular volume. If there is a decrease in plasma osmolarity, the osmoreceptors in the hypothalamus will signal for a decrease the secretion of ADH form the posterior pituitary. This means there…

Using the data obtained through the Labquest2 computer system, my group and I calculated exactly the initial momentum and kinetic energy, final momentum and kinetic energy, and percent of momentum and kinetic energy that was lost through these collisions. To calculate momentum we used the equation p_i=p_f which expands to m_1 v_1i+m_2 v_2i=m_1 v_1f+m_2 v_2f. We can say that our first hypothesis was accepted since in collisions 1 and 2 the total initial and final momentum was similar values.…

1762-IF4 is an Allen Bradley MicroLogix 1200 System with 4 Channel Current/Voltage Analog Input Module. It has a dimension of 90 x 87 x 40.4 mm. It has Delta-Sigma converter and 4 differential (bipolar) inputs. It’s analog operating voltage range is -10 – 10 V DC normal and -10.5 – 10.5 V DC full scale. It’s analog operating current range is 4 – 20 mA normal and -21 – 21 mA full scale. It converts the analog input up to the full-scale range. It enhances the functionality of MicroLogix 1200…

A great alternative to the Tech 21 Bass Driver is the MXR M80 BASS D.I.+. Although the basic concept is similar to the Tech 21 offering, MXR does include a gate to help keep processed signals quiet. Controls for shaping your tone include: bass, mid, treble, clean volume, distortion volume, gain, blend and a trigger adjustment for the included gate. This box is powered by phantom power, nine volt battery or wall wart. Patching capabilities include XLR , line level, and parallel outputs. All of…

produced so that it can be dissolved into the moisture in the body is excreted. Tadpoles already live in water so this is not a problem for the ammonia is diluted right away. (The Ecology and Behavior of Amphibians, 2010) Case Study 3: Diabetes in Australia Diabetes is a complex disease that affects the pancreas’s ability to produce insulin. Insulin is the hormone that regulates blood sugar, and without it leads serious damage to the body (WHO, 2015). It is a growing issue in Australia, and…

eliminate the current frustration at Goldman Sachs. Segarra is extremely knowledge and skilled in what she does so if she was moved to another bank she would be able to still use her tools there. The conflict of interest currently at Goldman is out of control and being able to allow her to continue her role or a similar role elsewhere would be in her best interest as well as for Goldman. If she is able to go to another bank and success she will be much better off. She probably still will have to…

Abstract:It is very important to control the speed of induction motors in industrial and engineering applications. Efficient control strategies are used for reducing operation cost too.This paper presents a direct flux and torque control of three phase induction motor drive using PI and Fuzzy logic controller. The Direct Flux and Torque Control (DTC) is one of the most excellent direct control strategies of stator flux and torque ripple of Induction Motor Drive(IMD). The conventional method of…

II. DERIVATION OF THE CONVERTER STRUCTURE The new generated topology is called Full-Bridge Hybrid Switched Capacitor (FBHSC) Inverter. A Half-Bridge version was previously presented [30]. The new topology was generated initially by differential connection [31]–[33] between two HSC dc-dc converter [16] (cf. Fig. 2a), which was generated as a bidirectional version of the HSC boost dc-dc converter [34], [35]. The unidirectional dc-dc version can be seen as an integration between a conventional…

Power wheelchairs have two main modules: the base (formed by the batteries, the controller, the wheels and the motors) and the seating system. The wheels configuration will have a direct effect on the wheelchair’s performance in different situations. As we have two types of wheels (drive wheels and castors), depending on how they are positioned and how the weight is distributed, they will be more or less efficient in different situations, environments, terrains, etc. The first critical…

Zero voltage switching can best be defined as conventional square wave power conversion during the switch’s on-time with “resonant” switching transitions. For the most part, it can be considered as square wave power utilizing a constant off-time control which varies the conversion frequency, or on-time to maintain regulation of the output voltage. For a given unit of time, this method is similar to fixed frequency conversion which uses an adjustable duty cycle, as shown in Fig. 1.…
