1, The full form of PTM is Pulse Time Modulation. It’s used on Academic & Science ,Electronics in Worldwide

Pulse Time Modulation (PTM) is a class of signaling technique that encodes the sample values of an analog signal onto the time axis of a digital signal.

The two main types of pulse time modulation are:
1. Pulse Width Modulation (PWM)
2. Pulse Position Modulation (PPM)

In PWM the sample values of the analog waveform are used to determine  the width of the pulse signal. Either instantaneous or natural sampling can be used.
In PPM the analog sample values determine the position of a narrow pulse relative to the clocking time. It is possible to obtain PPM from PWM by using a mono-stable multivibrator circuit.

2, The full form of PTM is Post-Translational Modification. It’s used on Medical ,Biochemistry in Worldwide

Post translational modifications refer to any alteration in the amino acid sequence of the protein after its synthesis.

It may involve the modification of the amino acid side chain, terminal amino or carboxyl group by means of covalent or enzymatic means following protein biosynthesis.

Generally, these modifications influence the structure, stability, activity, cellular localization or substrate specificity of the protein.

Post translational modification provides complexity to proteome for diverse function with limited number of genes.

Posttranslational modifications (PTMs) of proteins such as phosphorylation and ubiquitination are crucial for controlling protein stability, localization, and conformation. Genetic information encoded in DNA is transcribed, translated, and increases its complexity by multiple PTMs. Conformational change introduced by PTMs affects interacting partners of each proteins and their downstream signaling; therefore, PTMs are the major level of modulations of total outcome of living cells. Plants are living in harsh environment that requires unremitting physiological modulation to survive, and the plant response to various environment stresses is regulated by PTMs of proteins. This review deals with the novel knowledge of PTM-focused proteomic studies on various life conditions. PTMs are focused that mediate plant–environment interaction such as stress perception, protein homeostasis, control of energy shift, and defense by immune system. Integration of diverse signals on a protein via multiple PTMs is discussed as well, considering current situation where signal integration became an emerging area approached by systems biology into account.

3, The full form of PTM is Portugal. The Man. It’s used on News & Entertainment ,Music in United States

Portugal. The Man is an American rock band from Wasilla, Alaska, currently based in Portland, Oregon. The group consists of John Baldwin Gourley, Zach Carothers, Kyle O’Quin, Jason Sechrist, Eric Howk and Zoe Manville. Gourley and Carothers met and began playing music together in 2001 at Wasilla High School.

4, The full form of PTM is Parent Teacher Meetings . It’s used on Academic & Science ,Universities & Institutions in Worldwide

Parent-teacher conferences are usually once or twice a year at progress reporting periods. They are brief meetings, lasting about 10-30 minutes. Conferences are typically scheduled 1 to 2 months in advance. Some middle and high schools only request parent conferences to discuss problems. Most schools set aside specific dates and times for conferences, but if school schedules conflict with family schedules, it’s worth the effort to find a mutually convenient time, or even schedule a phone or video conference. Be mindful of special situations, such as divorced parents, single parents, or guardianships. Some divorced parents, for example, may prefer separate conferences.

While the main focus of parent-teacher conferences should be learning, it’s also important to discuss factors that can affect learning, such as students’ behavioral and social development. Other topics might include standardized test results, individualized education programs (IEPs), 504 education plans, peer relationships, classroom behavior, motivation and work habits, as well as students’ strengths and challenges.
