![]() Additionally, it’s important to nurture an environment of collaboration among team members in order to create accountability within the group. Setting clear expectations and involving the team in decisions regarding their work can give them an increased sense of motivation, as they will have ownership over their tasks and objectives. This can be a challenge, but there are many strategies you can use to help your team stay focused and on-task. When teams are under pressure, it’s essential to maintain high productivity and motivation in order to meet deadlines. If your team finds itself in a crunch, here are some tips to help them stay productive and motivated With these measures in place, it will be easier to avoid crunch time and still get the job done on-time. Be realistic about how much can be accomplished in a certain amount of time, communicate regularly with those you are working with, and take the necessary steps to ensure everyone’s needs are met without inviting undue stress. Managing expectations also plays an important role in avoiding crunch time. By planning ahead and accounting for unexpected delays and difficulties, you can set achievable goals that prevent a last-minute scramble to complete tasks. Setting realistic deadlines is essential for avoiding crunch time. ![]() To avoid crunch time, try to set realistic deadlines, plan ahead, and manage expectations When left unchecked these issues can have serious effects on the bottom line of an organization, so companies should be careful to not make crunch periods more lengthy than necessary and ensure their employees feel supported even during this challenging time. Symptoms of burnout include lost enthusiasm in the workplace, unhealthy levels of cynicism, and difficulty concentrating. Unfortunately, when stress becomes excessive or continuous, it can lead to burnout and job dissatisfaction among employees. If it happens too often, it can lead to burnout and job dissatisfactionĬrunch time is always a difficult period for workers, as it often involves long hours and a great deal of stress. ![]() On the other hand, good planning which takes into account available resources and realistic objectives helps keep teams on track to meet their goals. Unrealistic deadlines can cause unnecessary stress and strain on team members who can struggle to meet them without sacrificing quality. Scope creep is a common issue that happens when the scope of the project expands beyond its original intention without consideration for additional resources or budget needed to complete it. Without careful management of these components, tasks can become pushed back and the end result will lack quality or may not even be achieved at all. Unmet deadlines, poor planning, and scope creep can be serious issues in any project. It can be caused by unrealistic deadlines, poor planning, or scope creep Although crunch times are challenging, they can also be rewarding as it can motivate workers to bring projects to completion effectively and efficiently. This intensive period often entails long hours and cutting the number of breaks available for employees. ![]() The duration and intensity of crunch times may vary from project to project but generally crunch times refer to those final weeks of intense preparation for a deadline. ![]() “Crunch time” is a term used to describe the intense period of work leading up to a deadline, typically found in software development. “Crunch time” is a term used to describe the period of intense work leading up to a deadline Does your team ever hit a point where you’re working around the clock to meet a deadline? This is commonly referred to as “crunch time.” But what does that term really mean, and how can you tell if your team is truly in a crunch? Let’s take a closer look. ![]() ![]() ![]() There are some treasure troves of medieval music. (For more detail on this question, see the article here.) It is extremely rare for us to have any idea what the intended instrument was to accompany a voice (if at all) or to play for dances, so we have to make our own choices from the scant available information and our own sense of what sounds right. At times, though, it wasn’t written very accurately, or was written with a poor pen and so had vague or indecipherable note values, which is adequate if you know what it’s supposed to sound like, which they did, but we don’t. Square notation is now the best known system developed in this period, and once you know square notation some of the music is easy to read. There were different systems of musical notation, none of which indicated precise rhythm until the 12 th century. ![]() Medieval music is not immediately accessible for a modern musician. This ecclesiastical music is important in itself, but its predominance in surviving manuscripts gives a partial view of music-making. ![]() The music that was written down was most often church music as it was largely clergy who could write. Most people were illiterate, therefore most music was not written down but passed on and learned by ear and so, of course, we’ve lost it. Much of medieval secular music is a mystery. This gradual broadening of the idea makes it impossible to give a precise date for the end of the middle ages and the beginning of the renaissance, so a nominal latest date of around 1470 is often given. The idea of this alleged rediscovery of classical Roman and Greek art and wisdom (in reality, surviving manuscripts show that writers of the ‘middle ages’ were very well aware of classical Rome and Greece) spread steadily through the nation before then spreading internationally through Europe. Thus, for the people of the self-defined Italian renaissance who delineated the ‘middle ages’, the term meant precisely and explicitly the same as the ‘dark ages’: it was a whole millennium of cultural darkness in the middle period between the fall of the Roman Empire and Italian culture’s rediscovery of its treasures. It was Italians of the 14 th and 15 th century, primarily Francesco Petrarca or Petrarch, Leonardo Bruni and Flavio Biondo, who defined themselves and their generation as bringing about a renaissance (rebirth) of classical Roman and Greek wisdom. This split is an ahistorical view which ignores how the term ‘middle ages’ was originally conceived by those who minted it. Some historians have taken to splitting the mediaeval period in two: the ‘dark ages’ until the 10 th century (from an anglocentric view, that’s before the Norman invasion of 1066, when the language in England was Old English) and the ‘middle ages’ from the 11 th century (between the Norman conquest and the renaissance, during which the language evolved into Middle English). ![]() One of the creators, possibly the original creator, Francesco Petrarcha or Petrarch, 1304–1374, 476, following the fall of the Roman Empire, to the start of the renaissance in the 14 th and 15 th centuries, so that’s around a thousand years. The mediaeval or medieval period, or the middle ages, covers a huge stretch of time, from A.D. This article features 4 illustrative videos of medieval music and several links to further articles (click on blue text). When were the middle ages? How do we know what the music sounded like? What were the earliest surviving songs? What was its dance music like? Why does medieval music sound so different to today’s? How did medieval musicians harmonise? We’re not completely in the dark, though, so the aim of this article is to give a broad beginner’s guide to the principles of secular medieval music. The middle ages covers a period of a thousand years – and yet much of its music-making is a mystery to us. ![]() ![]() ![]() The AHB outdoor folding camping table offers huge storage bags and the capacity to hold things.

The standard atomic weight of aluminium is low in comparison with many other metals. This makes aluminium very useful in nuclear magnetic resonance (NMR), as its single stable isotope has a high NMR sensitivity. Nearly all aluminium on Earth is present as this isotope, which makes it a mononuclidic element and means that its standard atomic weight is virtually the same as that of the isotope. the only one that has existed on Earth in its current form since the formation of the planet. ![]() It is the only primordial aluminium isotope, i.e. This situation is common for elements with an odd atomic number. Because of the abundance of these salts, the potential for a biological role for them is of interest, and studies continue. In the 21st century, most aluminium was consumed in transportation, engineering, construction, and packaging in the United States, Western Europe, and Japan.ĭespite its prevalence in the environment, no living organism is known to use aluminium salts for metabolism, but aluminium is well tolerated by plants and animals. In 1954, aluminium became the most produced non-ferrous metal, surpassing copper. In World Wars I and II, aluminium was a crucial strategic resource for aviation. Aluminium became much more available to the public with the Hall–Héroult process developed independently by French engineer Paul Héroult and American engineer Charles Martin Hall in 1886, and the mass production of aluminium led to its extensive use in industry and everyday life. The first industrial production of aluminium was initiated by French chemist Henri Étienne Sainte-Claire Deville in 1856. The discovery of aluminium was announced in 1825 by Danish physicist Hans Christian Ørsted. It is obtained industrially by mining bauxite, a sedimentary rock rich in aluminium minerals. The strong affinity towards oxygen leads to aluminium's common association with oxygen in nature in the form of oxides for this reason, aluminium is found on Earth primarily in rocks in the crust, where it is the third-most abundant element, after oxygen and silicon, rather than in the mantle, and virtually never as the free metal. The aluminium cation Al 3+ is small and highly charged as such, it is polarizing, and bonds aluminium forms tend towards covalency. The radioactivity of 26Al is used in radiometric dating.Ĭhemically, aluminium is a post-transition metal in the boron group as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. It has one stable isotope: 27Al, which is highly abundant, making aluminium the twelfth-most common element in the universe.
