Frequently Asked Questions

For students

If I order a paper sample does that mean I'm cheating?

Not at all! There is nothing wrong with learning from samples. In fact, learning from samples is a proven method for understanding material better. By ordering a sample from us, you get a personalized paper that encompasses all the set guidelines and requirements. We encourage you to use these samples as a source of inspiration!

Why am I asked to pay a deposit in advance?

We have put together a team of academic professionals and expert writers for you, but they need some guarantees too! The deposit gives them confidence that they will be paid for their work. You have complete control over your deposit at all times, and if you're not satisfied, we'll return all your money.

How should I use my paper sample?

We value the honor code and believe in academic integrity. Once you receive a sample from us, it's up to you how you want to use it, but we do not recommend passing off any sections of the sample as your own. Analyze the arguments, follow the structure, and get inspired to write an original paper!

For teachers & parents

Are you a regular online paper writing service?

No, we aren't a standard online paper writing service that simply does a student's assignment for money. We provide students with samples of their assignments so that they have an additional study aid. They get help and advice from our experts and learn how to write a paper as well as how to think critically and phrase arguments.

How can I get use of your free tools?

Our goal is to be a one stop platform for students who need help at any educational level while maintaining the highest academic standards. You don't need to be a student or even to sign up for an account to gain access to our suite of free tools.

How can I be sure that my student did not copy paste a sample ordered here?

Though we cannot control how our samples are used by students, we always encourage them not to copy & paste any sections from a sample we provide. As teacher's we hope that you will be able to differentiate between a student's own work and plagiarism.

The role of Type I and Type II supernovae in nucleosynthesis is treated in some detail. It is concluded that e-process formation of the iron-group elements takes place in Type II supernovae, while r-process formation of the neutron-rich isotopes of the Cited by: Supernovae have long been the prime suspects. The earliest studies 1 suggested that the edge of the collapsing core of a type II supernova, ejecting a rich flux of neutrons, might be the site of the r-process.

For example, most of the iron and manganese in the sun and its planetary system were produced in thermonuclear supernovae. Apr 13,  · Supernova nucleosynthesis within exploding stars is largely responsible for the elements between oxygen and rubidium: from the ejection of elements produced during stellar nucleosynthesis; through explosive nucleosynthesis during the supernova explosion; and from the r-process (absorption of multiple neutrons) during the explosion. We summarize various explosion models of Type la supernovae and their nucleosynthesis features for both Chandrasekhar and sub-Chandrasekhar mass white dwarf models. These models provide different predictions of the photometric and spectroscopic variations among Type la supernovae, which are compared with observations. ib english essay structure

argumentative persuasive essay on homelessness - Nucleosynthesis in massive stars and in the supernova explosions, with subsequent distribution to the diffuse interstellar medium, may have occurred at variable rates, perhaps much more frequently in the early stages of galaxy formation than now. Studies of interstellar media in other galaxies can shed light on these subjects. May 30,  · Stellar nucleosynthesis is the process by which elements are created within stars by combining the protons and neutrons together from the nuclei of lighter elements. All of the atoms in the universe began as hydrogen. Feb 01,  · Elements heavier than helium are produced in the lives and deaths of stars.

essay on unity for kids - This included nucleosynthesis in the big bang, in supermassive population III stars, during late stellar evolution (AGB stars), and explosive nucleosynthesis on accreting white dwarfs (novae), accreting neutron stars (X-ray bursts), and supernovae. The nucleosynthesis is simulated using complex nuclear reaction network models for stellar. Careful input of such reaction rates in supernova simulations is especially crucial to assess the possibility of core-collapse supernovae as a site of the r-process nucleosynthesis [11,25].Because of their charged-current interaction electron neutrinos may play a role in reheating the stalled shock as well as regulating the neutron-to-proton ratio.
