Reaction Yield

Reaction Yield

The theoretical yield of a reaction is the amount of product estimated to form based on the stoichiometry of the balanced chemical equation. The theoretical yield assumes the complete conversion of the limiting reactant into the desired product. The amount of product that is obtained by performing the reaction is called the actual yield, and it may be less than or (very rarely) equal to the theoretical yield.

ATP Yield

ATP Yield

Cellular respiration produces 30 - 32 ATP per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport chain (ETC), 4 ATP are gained beforehand (2 from glycolysis and 2 from the citric acid cycle).
The ETC is embedded in the inner mitochondrial membrane and is comprised of four main protein complexes and an ATP synthase. NADH and FADH2 pass electrons to these complexes, which pump protons into the intermembrane space. This distribution of...

Yield Criteria for Ductile Materials under Plane Stress

Yield Criteria for Ductile Materials under Plane Stress

In designing structural elements and machine parts using ductile materials, it is crucial to ensure that these components withstand applied stresses without yielding. Yielding is initially determined through a tensile test, which evaluates the material's response to uniaxial stress. However, tensile stress is insufficient when components face biaxial or plane stress conditions This condition requires advanced criteria to predict failure.
The Maximum Shearing Stress Criterion, also known as...

Non-ohmic Devices

Non-ohmic Devices

In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.
Consider a simple circuit consisting of a battery, a diode, and a resistor. A...

Mnemonic Devices

Mnemonic Devices

Mnemonic devices are cognitive tools that facilitate memory retention by linking new information to familiar patterns or organizational strategies. These techniques are beneficial for remembering complex or lengthy sets of information by simplifying and structuring them in easily retrievable ways.
Acronyms
Acronyms are created by using the initial letters of a series of words to form a new word or phrase. This approach condenses complex information into a single, memorable entity. For example,...

Measures of Central Tendency

Measures of Central Tendency

The "center" of a data set is also a way of describing location. The two most widely used measures of the "center" of the data are the mean (average) and the median. The words "mean" and "average" are often used interchangeably. The substitution of one word for the other is common practice. The technical term is "arithmetic mean" and "average" is technically a center location. However, in practice among non-statisticians,...

Background:

Understanding spatial variation in crop yield is crucial for optimizing greenhouse management.
Traditional methods for monitoring plant status and yield can be labor-intensive and lack spatial detail.

Purpose of the Study:

To develop a novel method for visualizing spatial variations in plant status within a tomato greenhouse.
To leverage farm laborer activity data for creating detailed yield distribution maps.

Main Methods:

Estimating farm laborer position using smartphone radio wave strength and Bluetooth beacons.
Recognizing farm laborer actions through smartwatch motion data.
Visualizing spatial yield distribution as a 'harvesting map' based on collected data.

Main Results:

The system successfully visualized the spatial distribution of tomato yields.
The mean absolute error in harvested tomato counts per section was 0.35.
Farm managers found the harvesting map intuitive for understanding greenhouse conditions.

Conclusions:

The proposed approach effectively visualizes spatial yield variations in greenhouses.
Farm work information, when analyzed, provides valuable insights for agricultural management.
This technology offers a practical tool for enhancing greenhouse operational efficiency and yield monitoring.
