how permit to work is used and its importance in adhering
to the principles of HSE in an oil and gas environment
Answer:
These formal systems state exactly what work is to be done, where and when. In many organisations, people doing the actual work are required to sign a permit to work document to confirm that they have understood all processes and guidelines of the system. Permits also serve as a means of communication between site workers and the organisation’s management.
However, they should not be mistaken as a replacement for robust risk assessment, which should happen simultaneously. Having a permit to work systems as part of organisational operations reduces the risks of losses or damage due to unsafe activities in a non-trivial work atmosphere.
These systems ensure that the correct jobs are entrusted to appropriate individuals and review or audit of conditions are also undertaken by experts or authorised personnel who have proven capabilities of undertaking the respective responsibilities. Permit to work systems also confirms that work is completed safely and the workplace is restored to its safe, original form for normal operations to commence.

deduce the relationship between e.m.u and e.s.u in technology .
In the CGS system, the unit of charge is the charging unit (ESU). Also known as "Statistical Pendant" (StatC). In the CGS system, the load unit is the electromagnetic unit (E.M.E.).
The e.s.u. of charge, also known as franklin or statcoulomb, is the charge such that two similar q=1statC charges at a space of 1cm from each other exert an electrostatic force of 1dyn on each other.
The e.m.u. of current, also called the biot or abampere, is the current such that two infinitely-long straight, parallel conductors carrying 1abA of current and separated by 1cm exert a magnetostatic force of 2dyn on each other.
The relations between these units are such that
\(\frac{1 statC}{1 abA * 1s} = \frac{1 statC}{1abC} = \frac{1}{C} = \frac{1 statA}{1abA} = \frac{\frac{1 statC}{s} } {1 abA}\)
where c is the speed of light.
The ESU and EMU systems of electromagnetic units are different and they should generally be considered separate and independent (if relatively similar), and they do not coincide with the gaussian set of electromagnetic units.
For example, since the electrical displacement vector D is defined as \(E + 4\pi P\) in the ESU system and \(\frac{1}{c^{2} } E + 4\pi P\) the EMU system, it is not possible to exchange the formulas of one system for another without using a formula dictionary like the one at Jackson's end.

what divides the engineering stress-strain curve into two regions, namely, the elastic and plastic regions?
The engineering stress-strain curve is divided into two regions, the elastic and plastic regions, by a yield point.
The stress-strain curve is a graph that shows how materials react to stress. The material's physical and chemical properties are used to identify the stress-strain curve. Stress and strain are the two variables used in this model. Stress is a measure of the internal forces acting on a material, while strain is a measure of the material's deformation in response to the stress.
The linear portion of the stress-strain curve is referred to as the elastic region. The material returns to its original shape when the load is removed from this area of the curve. Young's modulus is the slope of this line, which represents the material's stiffness. If the stress is increased beyond the yield point, the material will deform in the plastic region.
The plastic region is the non-linear portion of the stress-strain curve. The material deforms in this region, and it will not return to its original shape if the load is removed. The strain-hardening slope, which represents the rate at which the material's strength increases as it deforms, is the slope of this region.

charging method .Constant current method
Answer:
There are three common methods of charging a battery; constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit.
Constant voltage allows the full current of the charger to flow into the battery until the power supply reaches its pre-set voltage. The current will then taper down to a minimum value once that voltage level is reached. The battery can be left connected to the charger until ready for use and will remain at that “float voltage”, trickle charging to compensate for normal battery self-discharge.
Constant current is a simple form of charging batteries, with the current level set at approximately 10% of the maximum battery rating. Charge times are relatively long with the disadvantage that the battery may overheat if it is over-charged, leading to premature battery replacement. This method is suitable for Ni-MH type of batteries. The battery must be disconnected, or a timer function used once charged.
Constant voltage / constant current (CVCC) is a combination of the above two methods. The charger limits the amount of current to a pre-set level until the battery reaches a pre-set voltage level. The current then reduces as the battery becomes fully charged. The lead acid battery uses the constant current constant voltage (CC/CV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation.

The given statement "each type of language sample requires different transcription codes and conventions" is true. Different transcription codes and conventions are necessary to effectively and accurately represent the specific aspects of each type of language sample.
Different types of language samples, such as spoken language, written language, sign language, or nonverbal communication, often require different transcription codes and conventions. Transcription is the process of converting spoken or signed language into written form, and it varies depending on the specific characteristics and features of the language being transcribed.
For example, when transcribing spoken language, conventions may include using specific symbols or notations to represent speech sounds, intonation patterns, pauses, or other phonetic or phonological features. On the other hand, transcribing sign language would require a different set of conventions, such as representing handshapes, movements, facial expressions, and body movements.
Similarly, transcribing written language may involve different considerations, such as punctuation, capitalization, and paragraph breaks. Nonverbal communication, which includes gestures, facial expressions, or body language, may require a different approach altogether, possibly using descriptions or visual representations to capture the intended meaning.
Each type of language sample has unique characteristics and features that need to be accurately captured in the transcription process.

(a) (6 points) Find the integer a in {0, 1,..., 26} such that a = -15 (mod 27). Explain. (b) (6 points) Which positive integers less than 12 are relatively prime to 12?
a. a = 12 is the solution to the given congruence relation. b. the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.
(a) The main answer: The integer a that satisfies a ≡ -15 (mod 27) is 12.
To find the value of a, we need to consider the congruence relation a ≡ -15 (mod 27). This means that a and -15 have the same remainder when divided by 27.
To determine the value of a, we can add multiples of 27 to -15 until we find a number that falls within the range of {0, 1,..., 26}. By adding 27 to -15, we get 12. Therefore, a = 12 is the solution to the given congruence relation.
(b) The main answer: The positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.
Supporting explanation: Two integers are relatively prime if their greatest common divisor (GCD) is 1. In this case, we are looking for positive integers that have no common factors with 12 other than 1.
To determine which numbers satisfy this condition, we can examine each positive integer less than 12 and calculate its GCD with 12.
For 1, the GCD(1, 12) = 1, which means it is relatively prime to 12.
For 2, the GCD(2, 12) = 2, so it is not relatively prime to 12.
For 3, the GCD(3, 12) = 3, so it is not relatively prime to 12.
For 4, the GCD(4, 12) = 4, so it is not relatively prime to 12.
For 5, the GCD(5, 12) = 1, which means it is relatively prime to 12.
For 6, the GCD(6, 12) = 6, so it is not relatively prime to 12.
For 7, the GCD(7, 12) = 1, which means it is relatively prime to 12.
For 8, the GCD(8, 12) = 4, so it is not relatively prime to 12.
For 9, the GCD(9, 12) = 3, so it is not relatively prime to 12.
For 10, the GCD(10, 12) = 2, so it is not relatively prime to 12.
For 11, the GCD(11, 12) = 1, which means it is relatively prime to 12.
Therefore, the positive integers less than 12 that are relatively prime to 12 are 1, 5, 7, and 11.
