Lung conditions, Brain conditions, Liver disease. Zebra-imaging Med's analytics engine can be used to identify conditions that may be present in CT scans for the liver, the brain, or the lungs.

A computed tomography scan, often known as a CAT scan or computed axial tomography scan, is a medical imaging procedure that produces precise inside images of the body. The individuals who perform CT scans are known as radiologists or radiography technologists. To measure the attenuations of X-rays by various tissues inside the body, CT scanners use a revolving X-ray tube and a row of detectors arranged in a gantry. Tomographic reconstruction procedures are then used to process the many X-ray data acquired from various angles on a computer to create tomographic (cross-sectional) images (virtual "slices") of a body. Patients who need a CT scan but cannot undergo an MRI do so because they have metallic implants or pacemakers.

The theoretical density of diamond given that the C-C distance and bond angle are 0.154 nm and 109.5° respectively is; 3.54 g/cm³

The first thing we will do is to get the unit cell edge length from the given C - C distance.

From the structure of diamond;

Φ = ¹/₂ * bond angle

Φ = ¹/₂ * 109.5°

Φ = 54.75°

Thus;

θ = 90° - 54.75°

θ = 35.25°

Let the height from a point to the base of the cube of the structure be x. Thus;

x = a/4 = y sin θ

where a is unit cell edge length and y is C -C length. Thus;

a = 4y sin θ

a = 4 * (0.154 * 10⁻⁹) * sin 35.25°

a = 3.56 * 10⁻⁸ cm

The unit cell volume is;

V_c = a³

Thus; V_c = (3.56 * 10⁻⁸)³

V_c = 4.51 * 10⁻²³ cm³

Now, there are 8 equivalent atoms per unit cell and as such density is calculated from;

ρ = (n * A_c)/(V_c * N_a)

A_c is atomic weight of diamond = 12.01 g/mol

N_a is avogadro's number = 6.022 * 10²² atoms/g

Thus;

ρ = (8 * 12.01)/(4.51 * 10⁻²³ * 6.022 * 10²²)

ρ = 3.54 g/cm³

Flash gas is a phenomenon that occurs when a liquid is suddenly released from a high-pressure vessel, causing some of it to rapidly vaporize into a gas. This sudden vaporization is caused by the decrease in pressure as the liquid is released into a lower-pressure environment.

Flash gas could be applicable in a variety of industries, such as oil and gas, where it can occur during the transportation of crude oil or natural gas. It can also occur in refrigeration systems, where it can cause a drop in efficiency and increased energy costs. To mitigate the effects of flash gas, various methods can be employed, such as using separators to remove the gas from the liquid stream or designing systems with lower pressure drops. Overall, understanding the phenomenon of flash gas is important in ensuring the safe and efficient operation of various industrial processes.

The correct answer is A. Total slack

Explanation:

Projects include multiple tasks or activities; moreover, each activity and the project itself have a specific due date. Besides this, activities can be delayed and this might affect or not the due date of the project. Indeed, some activities can have extra time without any effect on the date of the project, which is known as total slack or total float (delay in activities that does not delay the project.) Additionally, total slack is possible if activities or tasks are flexible, for example, if each task in a project should take 1 day and one of the tasks takes one day and a half, this can be compensated if another task takes less time. According to this, the correct answer is A.

Answer:

 So its area A = 4 * 4sqrt(2) = 16sqrt(2) inches^2

Explanation:

In order to find the area of the section, we need to find the length of one of the diagonals.

Using the Pythagorean Theorem, a^2 + b^2 = c^2, we pick any side of the cube which in

itself is a square with sides 4 inches each.  The length of the diagonal of the square is

2(4^2) = c^2  or c = 4sqrt(2).

To calculate the area of the section, we must first determine the length of one of the diagonals. Using the Pythagorean Theorem, \(\bold{a^2 + b^2 = c^2}\), one selects any side of the cube which in its a square with four-inch sides.

           \(\to 2(4^2) = c^2 \\\\ \to c = 4\sqrt{(2)}\)

      \(\to A = 4 \times 4\sqrt{(2)} = 16\sqrt{(2)}\ inches^2\)

Therefore, the answer is "\(\bold{ 16\sqrt{(2)}\ inches^2}\)".

Answer:

(c) member function

Explanation:

Polymorphism is when member functions in a class hierarchy perform differently, depending upon which object performs the call.

Polymorphism refers to the ability of different objects to respond to the same method call in different ways. In a class hierarchy, member functions (also known as methods) are defined in the base class and can be overridden or re-implemented in derived classes. When an object of a derived class is created, it can override the implementation of a method defined in the base class and provide its own version of that method.

For example, consider a class hierarchy in which the base class is "Shape" and there are derived classes called "Circle" and "Rectangle." The "Shape" class may define a method called "area()" that calculates the area of the shape. The "Circle" class may override the "area()" method and provide its own implementation that calculates the area of a circle using the radius of the circle, while the "Rectangle" class may override the "area()" method and provide its own implementation that calculates the area of a rectangle using its length and width.

When a method is called on an object of the "Circle" class, the object will use the implementation of the "area()" method provided in the "Circle" class to calculate the area. Similarly, when a method is called on an object of the "Rectangle" class, the object will use the implementation of the "area()" method provided in the "Rectangle" class to calculate the area. This is an example of polymorphism, as the same method call is being performed differently depending on the type of object that is performing the call.

In this context, the correct answer is (c) member functions.

2.) 126.96 degree centigrade

Explanation:

Given that a transparent film is to be bonded onto the top surface of a solid plate inside a heated chamber. For the bond to cure properly, a temperature of 70°C is to be maintained at the bond, between the film and the solid plate. The transparent film has a thickness of 1 mm and thermal conductivity of 0.05 W/m·K, while the solid plate is 13 mm thick and has a thermal conductivity of 1.2 W/m·K. Inside the heated chamber, the convection heat transfer coefficient is 70 W/m2·K. If the bottom surface of the solid plate is maintained at 52°C.

To determine the temperature inside the heated Chamber, let us first calculate the heat transfer rate per unit area through the plate by using the formula

Heat transfer rate R = k( Tb - T2)/L

Where

k = 1.2 W/mA.K

Tb = 70 degree

T2 = 52 degree

L = 13mm = 13/1000 = 0.013m

substitute all the parameters into the formula above.

R = 1.2 x ( 70 - 52 )/ 0.013

R = 1.2 x (18/0.013)

R = 1661. 5 W/m^2

the surface temperature of the transparent film will be

Ts = Tb + (RLf/Kf)

Ts = 70 + (1661.5 x 0.001)/0.05

Ts = 70 + (1.6615)/0.05

Ts = 70 + 33.23

Ts = 103.23 degree centigrade

the temperature inside the heated Chamber will be calculated by using the formula

Ti = Ts + (R/h)

Ti = 103.23 + (1661.5/70)

Ti = 103.23 + 23.74

Ti = 126.97 degree centigrade

Answer:

(a) the reversible power output of turbine is 5810 kw

(b) The second-law efficiency of he turbine = 86.05%

Explanation:

In state 1: the steam has a pressure of 6 MPa and 600°C. Obtain the enthalpy and entropy at this state.

h1 = 3658 kJ/kg s1=7.167 kJ/kgK

In state 2: the steam has a pressure of 50 kPa and 100°C. Obtain the enthalpy and entropy at this state

h2 = 2682kl/kg S2= 7.694 kJ/kg

Assuming that the energy balance equation given  

Wout=m [h1-h2+(v1²-v2²) /2]

Let

W =5 MW

V1= 80 m/s  V2= 140 m/s

h1 = 3658kJ/kg  h2 = 2682 kJ/kg

∴5 MW x1000 kW/ 1 MW =m [(3658-2682)+ ((80m/s)²-(140m/s)²)/2](1N /1kg m/ s²) *(1KJ/1000 Nm)

m = 5.158kg/s

Consider the energy balance equation given  

Wrev,out =Wout-mT0(s1-s2)

Substitute Wout =5 MW m = 5.158kg/s 7

s1=  7.167 kJ/kg-K            s2= 7.694kJ/kg-K and 25°C .

Wrev,out=(5 MW x 1000 kW /1 MW) -5.158x(273+25) Kx(7.167-7.694)

= 5810 kW

(a) Therefore, the reversible power output of turbine is 5810 kw.

The given values of quantities were substituted and the reversible power output are calculated.

(b) Calculating the second law efficiency of the turbine:  

η=Wout/W rev,out

Let Wout =  5 MW and Wrev,out = 5810 kW  

η=(5 MW x 1000 kW)/(1 MW *5810)  

η= 86.05%
