The last few days have been hectic for @irelandscape and, as a result, there has been little software development activity. There are a couple of known issues with the StemQ web site which are affecting the ranking of questions and answers on the home page. These will be looked at in priority in the coming days. Meanwhile, submissions of new Q&As is ongoing on the [web site](https://www.stemq.io). Read on for a sample of some of the best content published last week. An issue was reported which prevented some users to access StemQ from within their organization. This problem has now been fixed. ## What is StemQ? StemQ is a questions and answers (Q&A) application focusing on Science, Technology, Engineering and Mathematics (ST

Continuando con el tema del Cálculo Matricial, en esta oportunidad tocaremos algunos aspectos de las operaciones matriciales, en específico trataremos de ilustrar la multiplicación de una matriz por un vector, y la multiplicación entre matrices, dejando para el final una sección acerca de la eficiencia de estas operaciones a través de diversas normas o medidas de distancias, vista desde un punto de vista geométrico, y el error al medirlas. Es bueno mencionar, que el interés al desarrollar este tema, más que mostrar la teoría envuelta en el mismo, es recalcar de que manera podemos implementar estas operaciones con el uso de un computador con un software matemático como GNU Octave, el cuál es un Software Libre, o para aquellos que posean una Licencia de un Software súper conocido y usado por m

***The Egyptian god of chaos created a hellish binary Wolf-Rayet star. One of them will soon explode as a supernova. If any planets are going to be in its way, God save them.*** ![cassiopeia-a-11180_1920.jpg](https://cdn.steemitimages.com/DQmZdxM4bYkzGsSPg1iTNuwsBftm3Sgm6fqNbmwLy8RoyvF/cassiopeia-a-11180_1920.jpg) We already found many things in space. But the Apop star system is something else. If you know anything about Egyptian mythology you will know what I’m talking about as we gave it its name after the Egyptian god of chaos. About eight thousand light years away from us – luckily quite far away – two giant, bright and incredibly volatile Wolf-Rayet stars are orbiting each other. And if there is anything in space that could be classified as a demon it is a Wolf-Rayet star. And here we have two in one place! Astronomer Joe Callingham from the Australian University of Sydney and an international team are saying we haven’t seen anything like this in our galaxy. They say that one of the hellish

![DSC_0170.jpg](https://ipfs.busy.org/ipfs/QmTPFtZdwj3VsABrXXGp98yuHLZxhhrs4TTWH3BBWgW4Sz) One of the most spectacular butterflies is undoubtedly the majestic Macaon (Papilio Machaon) This butterfly is widespread in Europe, Asia, America and can also be found in city parks, in the countryside or in the woods. In India this butterfly is a protected species. Quite simple to recognize due to its size, design and color of its wings. The wings of Papilio Machaon are characterized by the yellow color with black veins and the characteristic presence of a blue crown and a red spot and, above all, by the typical tails. ![DSC_0172 (2).JPG](https://ipfs.busy.org/ipfs/QmaVxqNVvwjPru43bpqQqxLSrxngQ9hHPU7WERG9aaBMGE) The swallowtail butterflies fly from March to September. It is one of the largest daytime butterflies in Italy, in fact its wingspan can reach up to 10 cm. Papilio machaon feeds on the following nectarine plants such as Lantana Camara, Buddleja, Lonicera, Verbena. ![7ohP4GDMGPrUMp8dW6yuJTR9MKNu8P8DCXDU9qmmk

<div class="text-justify"> Hello Stemmians, I am delighted to write here; it feels really good. My name is Akinsiwaju Sanya, and I`m a writer and teacher. I studied English Education from the Lagos State University. I currently work as a writer for some prestigious organizations and I am a teacher of English. I love to meet new people, learn new things, travel, and I also do some reading. --- If there is one thing I am passionate about, it is eating healthy. So, I would like to share some knowledge on one of the important nutrients the body needs to stay healthy. Let's talk about zinc! I was such a playful child when I was younger, more like the life of the party in secondary school. I had many acquaintances and a few friends, however, I had a clique, and we were like brothers. Life was good until Ben, my best friend, who was also in that clique began to fall ill repeatedly. He would fall ill and recover, only to fall ill again. This was quite disturbing. We later got to know that he was zinc deficient, h

This has led many to try intermittent fasting, which combines the benefits of fasting with a more convenient lifestyle. Here I talk about the benefits of intermittent fasting, how it works, and my own personal experience with it.

<div class="text-justify">A couple of days ago, the temperature was around 20°C. I woke up this morning to see it is snowing outside. I guess the temperature at my place is dropping as fast as crypto is. There is, however, one thing that makes any morning just a bit better. It is a cup of hot black coffee. Liquid love. There were times when I had to drink tea instead of coffee and while it was nice, it just wasn't what it needed to be. Something was missing. I guess I am a coffee person and tea just won't do the job for me. How about you?

The definition of the word capital is private ownership of the means of production. The means of production do exist under every system, that is true. Private ownership, on the other hand, does not exist under every system. The basis of private property is control of something that you intend to extract profit from, and do not intend to use yourself. Your car and your computer are not private property. The same factory may be private property one day, and not be the next. You could say anything has the potential to be capital, but that's a pretty useless statement.

For those who are now doctors, surgeons and medical lecturers, I'm sure 5 to 20 years ago, you are a medical student yourself; I know I am and 1 year ago, I have graduated from being a ghost, crossing through the dimensional barrier and finally, a houseman which is equivalent to a foot soldier.

The world is divided into different types of climate. They are •polar • temperate • subtropical • tropical ![image](https://img.esteem.ws/dg5mwcxunl.jpg) • polar constantly cold; the land and sea are covered by thick ice sheets. • Temperate changeable weather, with warm dry summers and mild winters. • subtropical warm, with alternate dry and rainy seasons. •Tropical constant hot temperatures and daily rain showers Never any seasonal changes. Seasons : The season are caused by the Earth's orbits. For a few months each year half the Earth is tilted towards. the sun and gets strong heat rays, whilst the other half is tilted away and gets weak rays. The position is gradually reversed through the year. When it is summer in one hemisphere it is winter in the other. In autumn and spring the two hemispheres are an equal distance from the rays
