World Population Prospects - Population Division - United Nations

The 2019 Revision of World Population Prospects is the twenty-sixth round of official United Nations population estimates and projections that have been prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat. The main results are presented in a series of Excel files displaying key demographic indicators for each UN development group, World Bank income group, geographic region, Sustainable Development Goals (SDGs) region, subregion and country or area for selected periods or dates within 1950-2100. For advanced users who need to use these data in a database form or statistical software, we recommend to use the CSV format for bulk download. Special Aggregates also provide additional groupings of countries. Quick Navigation Disclaimer: This web site contains data tables, figures, maps, analyses and technical notes from the current revision of the World Population Prospects.

Chapter 7. Coding aloud: Readability - Seriously Good Software: Code that works, survives, and wins Writing readable code Documenting contracts using Javadoc comments Replacing implementation comments with self-documenting code Source code serves two very different kinds of users: programmers and computers. Computers are as happy with messy code as they are with clean, well-structured systems. On the other hand, we programmers are utterly sensitive to the shape of the program. L’Afrique, énigme démographique, par Henri Leridon (Le Monde diplomatique, novembre 2015) D’ici à 2050, la population de l’Afrique pourrait doubler, atteignant ainsi 2,4 milliards de personnes, avant de s’établir à 4 milliards vers 2100. Inattendues, ces projections démographiques établies par l’Organisation des Nations unies (1) bouleversent les perspectives de développement du continent, en particulier si on les met en rapport avec les chiffres de la croissance économique. Le dernier rapport de la Banque africaine de développement, de l’Organisation de coopération et de développement économiques (OCDE) et du Programme des Nations unies pour le développement (PNUD) sur l’avenir économique de l’Afrique (2) prévoit en effet que le taux de croissance moyen du produit intérieur brut (PIB) de 4,5 % observé au cours des quatre dernières années se maintiendra en 2015 et 2016. Actuellement, la population africaine croît de 2,5 % par an, pour une moyenne mondiale de 1,2 %. Cette situation résulte du maintien d’une forte fécondité. Indifférence des responsables sanitaires

Euthanasia allowed by Dutch court in cases of advanced dementia In the landmark decision, the court said that a physician may respond to a written request for euthanasia made before someone develops advanced dementia, provided certain legal requirements are met -- even if the patient's condition means they become unable to confirm that request. Euthanasia is legal in the Netherlands if the relevant criteria are met, which include a voluntary and well-considered request from the patient, "unbearable suffering without any prospect of improvement," and the lack of a "reasonable alternative," according to the Royal Dutch Medical Association. If those conditions are not met, the practice is still a punishable offense. In 2002, the Netherlands became the first country in the world to legalize euthanasia. Tuesday's ruling follows the criminal and disciplinary case against a nursing home doctor who in 2016 ended the life of a 74-year-old woman suffering from dementia. In its judgment Tuesday, the Supreme Court sought "to give direction to euthanasia lawmaking."

8 Shell Commands For Data Scientists There are many scenarios where you need to quickly analyze, modify and process large files, both in number and size. However, files are often text-based Comma Separated Values (CSV) files. Opening them with standard spreadsheet applications, such as Excel, LibreOffice or OpenOffice, overloads a machine's memory. Also, processing a large number of files in one batch often fails after a few hours because of some unexpected file anomaly. You inevitably spend a lot of time in frozen screens, restarts and long waits. However, most of these tasks could be carried out with a few lines of code.

Wood Fibrous material from trees or other plants Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material – a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees,[1] or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs.[citation needed] In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Fitbit Versa 2 Review: You'll Like The Watch, But Not The Subscription “The Fitbit Versa 2 has excellent battery life, but important fitness insights are locked behind a subscription.” Affordable Multi-day battery life Native sleep tracking On-device music storage Intuitive interface Offers few insights (without paying extra) Can’t stream from Spotify Looks like an Apple Watch knock-off Alexa is largely useless When the Fitbit Versa debuted, it filled a niche for people who wanted smartphone notifications but championed wellness first. It was a good compromise between the two, but didn’t deliver fully in either regard.

The School of Life presents: Forget finding happiness, instead find peace with anxiety It's therefore worth trying to understand why happiness 'ever after' should be congenitally so impossible. It isn't that we can't ever have a good relationship, a house or a pension. We may well have all this -- and more. It's simply that these won't be able to deliver what we hope for from them. We will still worry in the arms of a kind and interesting partner, we will still fret in a well-appointed kitchen, our terrors won't cease whatever income we have. It sounds implausible -- especially when these goods are still far out of our grasp -- but we should trust this fundamental truth in order to make an honest peace with the forbidding facts of the human condition.

'The big show': US poised to return to human spaceflight with historic launch In a historic moment a decade in the making, the skies above Florida will light up on Wednesday when the launch of a rocket born from a groundbreaking public-private partnership returns the United States to the business of human spaceflight. Not since the retirement of Nasa’s space shuttle fleet in 2011 has the US possessed the capability to send its own astronauts into orbit, and the success of this week’s mission, formally known as SpaceX Demo-2, is likely to shape the direction of the space agency’s near-Earth ambitions for a generation. At 4.33pm, a Dragon crew capsule attached to a Falcon 9 rocket is set to take flight from the Kennedy Space Center at Cape Canaveral, bound for the international space station (ISS).

Why Editas Medicine Is Now the CRISPR Stock to Really Watch Based on market cap, CRISPR Therapeutics (NASDAQ:CRSP) ranks as the top biotech focused on developing CRISPR gene-editing therapies. It's more than 2 1/2 times the size of Editas Medicine (NASDAQ:EDIT) and nearly four times larger than Intellia Therapeutics (NASDAQ:NTLA). But based on stock performance so far in 2020, Intellia wins the prize as the hottest CRISPR biotech stock. Its shares have soared more than 40%, thanks in large part to the expansion of its partnership with Regeneron.

The Parsemus Foundation sponsored a study by Dr. Raffaella Leoci to investigate a non-invasive treatment in dogs with benign prostatic hyperplasia (BPH). The pulsed electromagnetic frequency (PEMF) therapy was very effective at reducing the size of the prostate gland with only a few minutes of treatment each day. The foundation then supported a small clinical trial in men to see if the positive results translated to humans.

Early Detection: Digital Rectal Exam & PSA Test The earlier cancer is detected, the greater the chance that it can be treated successfully. Prostate cancer can be detected early, before symptoms develop, with a digital rectal exam (DRE) and the prostate-specific antigen (PSA) blood test. Digital Rectal Exam (DRE) The digital rectal exam enables your doctor to feel anything abnormal in the posterior (rear) area of your prostate, where most prostate cancers develop. Wearing a lubricated glove, the doctor will gently insert a finger into your rectum and check for any lumps or other irregularities that might be signs of prostate cancer.
