A bathroom or washroom is a room, typically in a home or other residential building, that contains either a bathtub or a shower (or both) ， The inclusion of a wash basin is common. In some parts of the world e.g. India, a toilet is typically included in the bathroom; in others, the toilet is typically given a dedicated room separate from the one allocated for personal hygiene activities. In North American English the word 'bathroom' is sometimes used to refer to any room in a residence that contains a toilet, regardless of the inclusion of a bath or shower.   Historically, bathing was often a collective activity, which took place in public baths. In some countries the shared social aspect of cleansing the body is still important, as for example with sento in Japan and the "Turkish bath" (also known by other names) throughout the Islamic world. The term for the place used to clean the body varies around the English-speaking world, as does the design of the room itself.

  Free water bottles are a thing now. It seems like someone at every conference, fitness class, or speaker series is handing you a bottle the second you walk in. Sure, it’s a nice perk, and you get something to drink while you’re dozing off in your chair. But have you ever considered what on Earth (literally) happens to these bottles once you’re done guzzling that water?   Chances are, those free water bottles are made of polyethylene terephthalate (PET), a type of polyester fabric. While PET isn’t great for the environment--it’s costly to produce, made from crude oil, and uses up a lot of energy to manufacture--it does have one great quality: it’s highly recyclable. rPET is the recycled version of your average water bottle, and, like a new iOS, it’s incredibly better than its PET predecessor in a multitude of ways.   Way more eco-friendly, rPET is like a second chance for synthetic materials. A second chance toward reducing landfills, lowering PET’s carbon footprint, and making a sust

  Yeast is a kind of fungus with simple morphological structure, rich in protein, vitamins, growth factors and other nutrients, and can produce single-cell protein. Yeast has unique efficacy and value in the treatment of organic wastewater. In addition, yeast also has the functions of preparing vaccines and removing fishy smell. The article summarizes and summarizes the application of various functions of yeast in aquaculture. The role of yeast in aquaculture Yeast cells are rich in protein, vitamins, growth factors and other nutrients, and have good palatability, and most of the yeast are non-toxic and can be eaten. In addition, yeast can produce various active extracellular enzymes such as cellulase, alkaline protease, amylase, lipase, phytase and other active extracellular enzymes and killing factors, which can be used as feed additives. Yeast is mainly used as a bait additive in aquaculture, and the yeast hydrolyzate product produced can partially replace fish meal. In recent years

  Pipe fittings are components used to join pipe sections to each other or other fluid control components (e.g., pumps and valves) to construct pipelines. Pipe valves are a type of pipe fitting designed to control the flow of fluid through a pipeline. Both are essential elements of piping systems across a wide range of industries.  At Seal Fast, we are a premier manufacturer and distributor of pipe valves and fittings. We offer a broad selection of quality products to customers in industries worldwide, including the agriculture, construction, mining, and marine sectors.  PIPE FITTINGS & VALVES FROM SEAL FAST At Seal Fast, our pipe fitting and valve offerings include:  Combination nipples  —  Combination nipples are cylindrical connectors used to join two sections of pipe. They can serve as reducing solutions if the pipes have different IDs. King Combination (KC) nipples  –  Similar to combination nipples, KC nipples connect two sections of piping. However, they are used when the pi

  A rectifier is a rectifying device, which in simple terms is a device that converts alternating current (AC) into direct current (DC). It has two main functions: first, to convert alternating current (AC) into direct current (DC), which is filtered and supplied to the load, or to the inverter; second, to provide charging voltage to the battery. Therefore, it also acts as a charger at the same time. The alternating current generated by the automobile generator is converted into direct current after being rectified by the rectifier, but its waveform still has irregular fluctuations, which directly affects the accuracy of vehicle ignition; the output voltage cannot be kept relatively constant, resulting in the energy difference of each spark plug ignition, which is easy to The engine of the vehicle is shaken, the gear shift is stuttered, the acceleration is slow and weak, the idle speed is unstable, and the efficiency of the vehicle air conditioner is low. As a result, the performance a

    Due to the sudden outbreak of the new crown pneumonia epidemic, the demand for protective equipment such as masks and protective clothing has increased sharply. The following is a summary of the  medical supplies  needed to deal with the epidemic. (1) Protective products Personal protective equipment refers to the personal protective equipment provided to protect workers from or reduce the injury of accidents and occupational hazards in the process of labor production, and directly protect the human body. According to the purpose, personal protective equipment can be classified into household personal protective equipment, recreational personal protective equipment and medical personal protective equipment, among which medical personal protective equipment such as  medical masks ,  medical protective clothing , medical goggles, etc. Pneumonia is important. The medical protective mask has a good fit with the wearer's face, can filter particles in the air, block pollutants such a
