  • Biodigesteur domestique  + (Un biodigesteur est une solution techniqueUn biodigesteur est une solution technique de valorisation des déchets organiques utilisée pour produire un gaz combustible (le biogaz) et un fertilisant (le digestat). La particularité du biodigesteur est que la dégradation est réalisé par des bactéries dans un milieu privé d’oxygène, on parle de fermentation anaérobique. Le biogaz est un mélange de gaz contenant principalement du méthane, il peut être utilisé pour alimenter un bruleur de gazinière ou de chaudière ou bien comme combustible pour des moteurs. La fermentation méthanogène qui se produit dans le biodigesteur existe dans la nature. C’est par exemple ce qui se produit dans les marais lorsque de la matière organique se décompose sous l’eau. Les feu-follets sont de petites torchères de biogaz. La domestication du biogaz remonte au début du XIXe siècle et le nombre et la variété de biodigesteurs n’ont cessé de croitre depuis. Ils sont particulièrement présents dans les pays en développement de la ceinture tropicale où la petite paysannerie s’autonomise en énergie grâce à leur production de gaz avec leurs déchets organiques. La chaleur étant un catalyseur important de la fermentation, sous ces latitudes, de petites unités sont économiquement intéressantes. En France et dans les pays développés, le coût de l’énergie étant très faible par rapport à celui de la main d’œuvre, peu de petits digesteurs existent. Cependant de nombreuses installations industrielles équipent les stations d’épurations et les grands élevages agricoles. Il existe plusieurs types de biodigesteurs, continus ou discontinus, et avec des plages de production selon la température (psychrophile : 15-25°C, mésophile : 25-45°C ou thermophile : 45 – 65°C). Nous allons étudier les biodigesteurs continus mésophiles à 38°C, solutions les plus utilisées en zone tempérée. La caractéristique principale de ce système est sa ressemblance avec un système digestif. Tout comme lui, il cultive des bactéries, a besoin d’une certaine température pour être efficace et reçoit une alimentation régulièrement. Dans un compost, en milieu aérobie, la décomposition des matières organiques conduit à la formation de gaz (H2S, H2, NH3) et à une production de chaleur importante. Seule la décomposition à l’abri de l’air conduit à la formation du méthane. C’est une des raisons pour laquelle la fermentation a lieu dans une cuve étanche. Dans ce tutoriel nous allons étudier les différents éléments constituants un biodigesteur (circuit matière et circuit gaz) et comment l’utiliser. Cette documentation réalisée avec l’association Picojoule retrace la fabrication d’un de leurs prototypes de micro-méthanisation, il ne permet pas l'autonomie en gaz de cuisson mais est une bonne introduction à la biodigestion. Le digesteur semi-enterré d'Hélie Marchand à Madagascar est de plus grande capacité : [https://lowtechlab.org/wiki/Biodigesteur Biodigesteur] Les explications sont largement inspirées du travail de Bernard LAGRANGE dans ses ouvrages Biométhane 1 et 2, que nous vous recommandons vivement !

  • Mood Box, Sons et Lumières/fr  + (Vous trouverez dans ce paragraphe le projeVous trouverez dans ce paragraphe le projet décrit un peu plus en détail. === Préambule === Ce projet est un projet de groupe (FaB team) réalisé dans le cadre de la formation hybride "Fabrication Numérique", promotion juillet 2018. Ce projet de fin de parcours met en œuvre une partie des savoir-faire acquis au cours de celle-ci et scelle la formation. Il vient donc en complément du projet "bentolux" qui sera bientôt documenté et référencé sur wikifab.org . Les instructions de base étaient les suivantes : * concevoir un nouvel étage sur une boîte existante conçue au fil de la formation (3 étages possibles à disposition : 1 socle, 1 en plexiglas, 1 pour l'écran LCD) ; * utiliser pour ce nouvel étage les connaissances acquises : impression 3D, découpe laser, etc ; * programmer via Arduino au moins une interaction avec l'utilisateur (à nous de choisir cette dernière). === Spécifications générales === Après réflexion, notre groupe a décidé de créer l'étage musical "Mood Box" qui viendrait compléter la station météo déjà prévue avec l'étage socle et l'étage écran LCD. Le comportement prévu est décrit dans les paragraphes ci-dessous. ==== Démarrage de la boîte ==== Une fois le bloc d'alimentation correctement branché, le démarrage de la boîte est réalisé par le biais de l'interrupteur en façade. Ce démarrage déclenche les événements suivants : * la figurine au sommet de la boîte tourne sur son support ; * cette "danse" est agrémentée d'une animation lumineuse via l'anneau de LEDs situé sous le support de la figurine ; * l'écran LCD affiche un message de bienvenue. S'il n'y a aucune autre action dans la foulée, la boîte passe en mode "veille". Dans ce mode, l'écran LCD affiche la température et le taux d'humidité accompagnés d'un message. Ces messages comme la couleur appliquée à l'anneau de Leds et au fond de l'écran LCD dépendent de la température détectée, à savoir : * la couleur (LCD/Led-ring) varie du bleu au rouge proportionnellement à la température ; * le led-ring scintille à une fréquence aléatoire pour donner de l'animation ; * un message variable par tranche est affiché sur l'écran LCD. ==== Activation de la Mood Box et comportement ==== La Mood Box est activée lorsque l'utilisateur appuie sur la barre de laiton située au sommet de la boîte (cette barre est une extension de la touche capacitive installée à l'intérieur de la boîte). Cette activation est accompagnée d'une animation conjointe de la figurine, de l'anneau de LEDs et de l'écran LCD.
    Si aucun autre appui n'est effectué sur la barre dans les 5 secondes suivant l'activation, la Mood Box est désactivée et le mode veille reprend.
    Un nouvel appui déclenche le mode lecture.
    Pour faciliter l'utilisation de la barre, un affichage itératif de leds permet un comptage visuel direct des "clics" effectués.
    La première fois, la lecture de la musique démarre au tout début de la liste de lecture. Le bouton du potentiomètre est alors actif et permet de régler le volume de la musique jouée. La barre reste quant à elle disponible pour agir sur la musique jouée. Pendant la lecture, si la barre est touchée : *  1 fois : "pause/play", i.e. la musique est mise en pause ou en lecture suivant l'état précédent, avec un affichage spécifique sur l'écran LCD ; *  2 fois : "next", i.e. la lecture passe au titre suivant de la liste de lecture ; *  3 fois : "previous", i.e. la lecture repasse au titre précédent de la liste de lecture ; *  4 fois ou plus : retour au mode "veille", avec une animation conjointe de l'anneau de LEDs, de la figurine et de l'écran LCD. Remarque : chacune des actions pause/play/next/previous génère un changement de rotation de la figurine. Pendant la lecture, l'anneau de LEDs est en mode "arc-en-ciel" et la figurine tourne sur elle-même. ==== Désactivation de la Mood Box ==== Après activation de la Mood Box ou après l'arrêt volontaire de la musique, si aucun appui n'est effectué dans les 5 secondes, le mode veille reprend et la Mood Box est désactivée. Il est à noter que si l'on relance la lecture depuis le mode "veille", celle-ci va reprendre exactement là où on l'avait interrompue.

  • Heat Pump vs. Air Conditioner  + (When it comes to heating and cooling your When it comes to heating and cooling your home, the choice between a heat pump from [https://zealux.com heat pump manufacturer] and an air conditioner (AC) depends on various factors, including climate, energy efficiency, installation costs, and personal preferences. Both systems offer distinct advantages and disadvantages, making it essential to understand their differences to determine which option is better suited to your needs. === Heat Pump vs. Air Conditioner: Understanding the Differences === '''1. Heating and Cooling Capability:''' * '''Heat Pump:''' Unlike air conditioners, heat pumps can provide both heating and cooling functions. During the warmer months, heat pumps operate like traditional AC units, extracting heat from indoor spaces and transferring it outside to cool the air. In colder months, however, heat pumps reverse this process, extracting heat from outdoor air (even in cold temperatures) and transferring it indoors to warm the home. * '''Air Conditioner:''' Air conditioners are designed solely for cooling purposes. They remove heat from indoor air and transfer it outside, resulting in a cooler indoor environment. Unlike heat pumps, air conditioners cannot provide heating during colder months. '''2. Energy Efficiency:''' * '''Heat Pump:''' Heat pumps are known for their energy efficiency, as they utilize electricity to transfer heat rather than generate it. By moving heat rather than creating it through combustion, heat pumps can provide efficient heating and cooling, resulting in potential energy savings on utility bills. * '''Air Conditioner:''' While modern air conditioners have become more energy-efficient over the years, they typically consume more electricity than heat pumps, especially during the cooling season. Air conditioners rely on electricity to power compressors and fans to cool indoor spaces. '''3. Climate Considerations:''' * '''Heat Pump:''' Heat pumps are most effective in moderate climates where temperatures rarely drop below freezing. In regions with mild winters, heat pumps can efficiently provide both heating and cooling, offering year-round comfort. However, in areas with extremely cold temperatures, the efficiency of heat pumps may decrease, requiring supplemental heating sources or backup systems. * '''Air Conditioner:''' Air conditioners are well-suited for cooling in all climates, regardless of temperature variations. They perform efficiently in hot and humid climates, where cooling demands are high during the summer months. '''4. Installation and Initial Costs:''' * '''Heat Pump:''' The installation costs of heat pumps are typically higher than those of air conditioners, primarily due to their dual heating and cooling capabilities. Heat pump systems require additional components, such as reversing valves and supplementary heating elements, which can increase upfront expenses. * '''Air Conditioner:''' Air conditioners are generally more affordable to purchase and install compared to heat pumps. Since they only provide cooling, air conditioning systems are simpler in design and require fewer components, resulting in lower installation costs. '''5. Long-Term Maintenance:''' * '''Heat Pump:''' Heat pumps require regular maintenance to ensure optimal performance and efficiency. Routine tasks include filter replacement, coil cleaning, refrigerant checks, and system inspections. Neglecting maintenance can lead to reduced efficiency and increased energy consumption. * '''Air Conditioner:''' Like heat pumps, air conditioners also require regular maintenance to ensure proper operation. Routine tasks include filter replacement, coil cleaning, refrigerant checks, and system inspections. Proper maintenance can prolong the lifespan of the air conditioning system and prevent costly repairs. === Conclusion: === Choosing between a heat pump and an air conditioner depends on various factors, including climate, energy efficiency, installation costs, and personal preferences. Heat pumps offer the advantage of providing both heating and cooling functions, making them suitable for moderate climates. They are energy-efficient and can result in potential energy savings on utility bills. However, in regions with extremely cold temperatures, the efficiency of heat pumps may decrease, requiring supplemental heating sources. On the other hand, air conditioners are specifically designed for cooling and are well-suited for all climates. They are generally more affordable to purchase and install compared to heat pumps. While air conditioners consume more electricity than heat pumps, modern models have become increasingly energy-efficient. Ultimately, the decision between a heat pump like [https://zealux.com/product-category/inverboost-pool-heat-pump/ pool heat pump] and an air conditioner depends on your specific heating and cooling needs, budget considerations, and regional climate conditions.

  • Hot Water Systems and Maintenance  + (With the summer just around the corner, itWith the summer just around the corner, it's time to prepare your Hot Water System for the hot season ahead. Although summers aren't as stressful as winters on your [https://en.wikipedia.org/wiki/Water_heating Hot Water System,] the hot and humid season comes with its own unique problems. Today Budget Plumbing will discuss the top 4 most common problems (and maintenance you can do) for Hot Water Systems! == Common Hot Water System Problems You Can Face In Summer == Sometimes our Hot Water Systems are can be overly problematic and just too far gone, if you are looking for a quality electric or gas hot water system, check out our collection of [https://www.budgetplumbingcentre.com.au/product-category/hot-water-systems/ storage and instant hot water systems] from the best bathroom suppliers Perth. [https://www.budgetplumbingcentre.com.au/product-category/hot-water-systems/gas/ Gas] and [https://www.budgetplumbingcentre.com.au/product-category/hot-water-systems/electric/ Electric] hot water systems require equal care in summer as they do in winter to continue to provide warm water despite the increasing temperatures, as we come into the Perth summer, here are a few Hot Water System maintenance tips. === 1. Adjusting Temperature Settings === The Perth cold winters sometimes require us to turn the temperature settings of the Hot Water System higher by a few degrees. After all, your Hot Water System has to fight off the West Australian cold snaps and work harder to produce hot water in the winter; this is especially true if you have a [https://www.budgetplumbingcentre.com.au/product-category/hot-water-systems/gas/gas-storage/ storage system]. Conversely in the hot Perth summer heating water doesn’t require extra effort to overcome scorching temperature differences. This can lead your heater to produce scalding hot water. Adjusting the temperature of your water heater lower will reduce the risk of burns and also decrease your utility bills.  Budget Plumbing Centre has many options for hot water systems in your home. === 2. Excess Mineral Build-up === Summers often lead to a massive rise in overall water usage. If you are like my family who needs scalding hot water even during summers, then potentially your Hot Water System will be under a lot of pressure. Frequent and increased usage will naturally increase the mineral build-up in the Hot Water System pipes (especially if you’re in a “hard water” area). This can reduce the flow of hot water, contaminate the water flowing out and negatively affect its functioning if left unattended for long periods of time. A very easy solution is to frequently run maintenance on your Hot Water System and clear out the sediments/Mineral build up.   This all can be done by simply opening the pressure relief valve on your hot water system (usually you will have two of them to open). === 3. Shortage of Warm Water === Did you know that summer increases the need for water in your household?  It sometimes seems counter intuitive, but summer brings with it more sweaty laundry and more frequent showers.  I have a storage system, two daughters and if your family is like mine we get 2-3 continuous showers and there is no more hot water left.

  • My Lil' Pumpkin  + (" Economic and social progress over the la" Economic and social progress over the last century has been accompanied by environmental degradation that is endangering the very systems on which our future development — indeed, our very survival — depends. Each year, an estimated one third of all food produced – equivalent to 1.3 billion tonnes worth around $1 trillion – ends up rotting in the bins of consumers and retailers, or spoiling due to poor transportation and harvesting practices." - United Nations, Sustainable Development Goals Social progress has been stunted in disadvantaged communities which has contributed to the underdevelopment of the citizenstin these communities. As a human race, we can argue that environmental degradation is a result of the unethical production methods used to over-produce goods that we want but don't need. As a human race we even go as far as arguing thag we have to move towards more sustainable methods of producing goods however this "new and more sustainable" knowledge of doing things is only shared with the privileged few. The marginalized and impoverished majority of the human race is not empowered with the knowledge of how they can improve their lives and also be key players in the adoption of new and improved sustainable practices and principles that need to be adopted in order to leave the world that we live in as a better place for future generations to come. To ensure that the concept of sustainable living is adopted across all social classes; equal access to sustainable principals and practices as a knowledge base and complimentary skillsets must be available to all. Urban farming specialist, UFarm KZN Agro, and agri-education expert, The AgriCUL Institute, have paired up as the My Lil' Pumpkin team to answer the Sustainable Development Goal 12 - Sustainable Production & Consumption. We have used recycled PVC pipes, plastic bottles and disposable cups to create a Hydroponics System that can be easily recreated by the youth living in a disadvantaged communities. Having this hydroponic knowledge and skillset will empower the youth to be able to grow their own food, change their perspective of what they understand to be waste/scrap and begin to understand its potential value, understand that it is possible to grow food without harming using soil and thereby degrading our natural soil, how to grow food without using vat amounts of water as well as the importance of water harvesting as a method of water conservation. Introduction to Water Hydroponics '''WHAT:''' “Hydro” is the Greek word for water, and “ponos” means work. In hydroponic gardening, the water does the work—in this case, the work of delivering nutrients to the plant roots. Simply put, hydroponic gardening is a method of growing plants without soil. '''WHY:''' Many experts in agriculture consider hydroponic gardening to be much more than just a cool way for home gardeners to grow a few plants. They see it as the future of food production, because hydroponic gardens can be made to fit just about anywhere and allow even un-farmable areas to grow nourishing food. Because the food is dissolved in water, it goes directly to the roots. Plants grow faster and are ready for harvest sooner. You can grow more plants in the same space as you can with a soil garden, and since there’s no soil, there’s no worry about soil-borne diseases or pests – and no weeding. '''HOW:''' The water culture system is the simplest of all active hydroponic systems. The platform that holds the plants is usually made of Styrofoam and floats directly on the nutrient solution. An air pump supplies air to the air stone that bubbles the nutrient solution and supplies oxygen to the roots of the plants. Water culture is the system of choice for growing leaf lettuce, which are fast growing water loving plants, making them an ideal choice for this type of hydroponic system. Very few plants other than lettuce will do well in this type of system. This type of hydroponic system is great for the classroom and is popular with teachers. A very inexpensive system can be made out of an old aquarium or other water tight container.n old aquarium or other water tight container.)

    Mais en boucle ouverte, il n'a pas de régulation de courant, pour ne pas avoir de dépassement du courant maximum, une rampe du rapport cyclique sera utilisé.

    Une routine d'interruption de 0.1 seconde sera utilisé pour faire la mesure de la tension est du courant (échantillon de mesure, sample ). Ce temps de sampler est arbitraire, mais ne permet pas d'être plus rapide que le temps de montée du courant car la constante de temps électrique du moteur étant de  L/R= 1.5ms.

    Le fonctionnement en boucle ouverte avec une rampe de 25.5s (8bit et routine d'interruption de 0.1s) permet de bien comprendre la problématique du fonctionnement d'une commande à moteur DC.

    l'affichage se fera seulement tous les 0.2s pour avoir une stabilité des chiffres à l’écran. De plus, un filtrage numérique, se fera sur le courant et la tension sur 4 valeurs donc sur 0.4s.

  • What is Bonus Shares  + ('''Bonus shares''' are free additional sha'''Bonus shares''' are free additional shares that are issued to existing shareholders based on the amount of shares they own. Rather than being given as dividends, the company's cumulative earnings are turned into free shares. For instance, if a firm offers one bonus share for two shares, an existing shareholder will receive one more shares for two existing share. Let’s assume that a shareholder owns 1,000 shares in the company. He will receive 500 bonus shares when the firm releases bonus shares, i.e. (1000 * 1/2 = 500). The terms '''"record date"''' and '''"ex-date"''' are used when the corporation issues bonus shares to its shareholders. Let's look at what the terms "record date" and "ex-date" mean: == What is the record date of bonus shares? == The record date is the cut-off date set by the corporation for bonus shares eligibility. The corporation will issue bonus shares to all shareholders who have shares in their '''Demat account''' on the record date. == What is Ex-Date of bonus shares? == The record date is one day prior than the ex-date. To be eligible for bonus shares, an investor must purchase the shares at least one day before the ex-date. == The following are the two different types of bonus shares: == 1) Bonus shares that are fully paid 2) Bonus shares that are partly paid === Bonus Shares that are fully paid === Fully paid bonus shares are those that are distributed at no additional expense in proportion to the amount of stock held by investors. Bonus shares of this type can be obtained from the following sources: 1)      Profit and loss account 2)      Security Premium Account 3)      Capital Reserves 4)      Capital redemption reserves === Bonus Shares that are paid partly === Let's start with a definition of a partly-paid share before moving on to party-paid up bonus shares. A partly paid share is one that has only been partially paid in comparison to the full issue price. It means that an investor can purchase partially paid shares without having to pay the entire issue price. However, when the corporation makes calls, the remaining sum for partially paid shares can be paid in installments. When a bonus is applied to partly-paid shares and changed into fully paid shares without calling out the uncalled amount through profit capitalization, partially-paid up bonus shares are generated. Partly paid-up bonus shares, on the other hand, cannot be issued through a capital redemption reserve account or a security account, unlike fully paid-up bonus shares. == Advantages of Bonus Shares == '''From the viewpoint of the Investor's''' 1) When investors receive bonus shares from the corporation, they are not required to pay any taxes. 2) Bonus shares are useful to long-term shareholders who want to increase the value of their investment. 3) Bonus shares are issued by the company at no cost to shareholders, increasing the number of outstanding shares of an investment in the company and increasing the stock's liquidity. 4) Bonus shares contribute to an investor's trust in the firm's business and operations by allowing the investor to participate in the company and receive capital in return. Find [https://www.indiratrade.com/ India's Best Stock Broker] because its one of the major part for successful [https://www.indiratrade.com/algo-trading algo trading]. '''From the viewpoint of the company''' 1) The issuance of bonus shares boosts the company's worth and improves its market position and image, earning the trust of existing shareholders and attracting a number of small investors to the '''stock market'''. 2) With the issuance of bonus shares on the market, the companies have more free-floating shares. 3) The issuance of bonus shares helps corporations get out of situations where they are unable or unwilling to pay cash dividends to their shareholders. === How to Invest in Equities & Commodities === Find the best commodity and '''[https://www.indiratrade.com/equity best equity broker in india]''' Both '''commodity''' and '''equity markets''' are different ways for investors to make money and get a decent return on their investments.

What is the author's scientific background and orientation? Is he/she a specialist in the field or new to the field? When cross-reading, always keep your question for the text in mind and critically examine whether and for what you can and would like to use the text. Have the "courage to leave gaps": When you first read the text, leave out chapters or passages that lead you too far away from your question! Note down ideas, associations and cross-references already during the first reading: Even if you are sure that this or that thought is obvious - it often does not come a second time ... Various institutions offer courses in speed reading, which train you to quickly grasp the content of texts without reading word for word. If you are interested in this: Acquire this technique in advance so that you are prepared for the emergency! '''Structuring the material''' Reading and editing your sources in a structuring way is a necessary endeavor, and it also has many benefits: It makes the content of the text clearer; books don't have to be read repeatedly; you create "material" for yourself that you can work with further without problems. With the systematic reading, editing and excerpting of readings, you create material for yourself with which you can continue to work in a well-founded manner. The excerpted material is a first text form that you have created in keywords. The next step is the first formulation of your keywords in complete sentences.
