The Human Heart: A General Description The heart is the main organ of the cardiovascular system in the human body. Its primary function is to pump oxygen- and nutrient-rich blood throughout the 60,000 miles of blood vessels that make up this system ("Heart, 2015"). About the size of a clenched fist, the heart is located in the middle of the chest, between the lungs and nestled behind the ribcage. It lies a little to the left of the sternum. The shape of the heart is reminiscent of an upside…
higher levels of your full potential and increase your overall body efficiency. Many products have been produced and their production has greatly increased over the years due to continuous exploitation of new research techniques and needs in every field of life. Irrespective of the products and ideas born, the human needs of 21st century are endless and cardinal. It’s the creativity and ultimate needs which go hand in hand…
T-tubule membrane. DHPR plays a role in excitation-contraction coupling in both skeletal and cardiac muscle, it specifically facilitates the release of Ca++ during muscle contraction. Even though DHPR is present in both skeletal and cardiac muscle, it functions differently in the two muscle types. DHPR in skeletal muscle is physically connected to the ryanodine receptor (RyR), thus, Ca++ release in skeletal muscle is due to the conformational change in DHRP (electromechanical coupling). However,…
Electrical and mechanical functions integrated in the nanoscale range led to the development of the new age devices, Nanoelectromechanical systems (NEMS). These devices because of their size, they come with properties such as reduced mass, high quality factor (Q factor) and very high fundamental resonance frequencies. These qualities of NEMS makes them desirable for numerable applications such as components of signal processing devices, actuators and high speed sensors. NEMS can be used to…
leading people towards success. The effective management and leadership processes applied at the company make it manage three principle businesses in Australia, Asia, and New Zealand. On the other hand, the application of both management and leadership function makes it easier the organization to combine different activities that ensure high productivity and adherence to the company’s rules and…
Inhalation of fuel vapor along with dust may lead to significant impairment of lung and other body functions. Traffic police personnel, due to their continuous and prolonged exposure are likely to be the worst affected group in this regard. Duration of exposure, aging, concurrent smoking may influence the pulmonary function in these populations. Many studies in the past have documented impaired respiratory function among traffic policemen, attributable to their long term exposure for vehicular…
The shape of the system at point 1 and 2 are labeled and shown below (Figure 5.12). The moment of the system was solved for in ABAQUS and superimposed in red over the shape of the column. It can be seen that the system moment is zero in a variety of places over the course of the loading. One place the moment it zero here is at L/2. The moment at L/2 is only zero during line-contact. Due to the symmetric nature of the buckling sequence, line-contact repeats here throughout the course of…
Paul V. and Joseph E. Galvin which sold battery-eliminators as their first product but due to organization failure, it ended on October 30, 2014 (Motorola 2006). The essay below will compare and contrast these two companies by using the Fayol’s four function namely, planning, organising, leading and controlling. (Waddell, Jones, and George 2013). “Planning” is to choose suitable organisational goals and ways of action to achieve the goals. (Waddell, Jones, and George 2013) Planning means…
The functions of FGFR3 are dependent on ligands, specifically fibroblast growth factor (FGF) and heparin sulfate proteoglycans (6). These ligands bind to the D2, and D3 immunoglobulin subdomains of FGFR3 to stabilize the dimer complex as well as augment the functions of FGFR3. Conversely, D1 functions to inhibit FGFR3. Although the D2 and D3 immunoglobulins trigger the functions of FGFR3. FGFR3 can phosphorylate marginally without the ligation…
