Off-road motorcycles include many types designed for dirt-oriented racing, including many series, such as B series, K series, G series and H series, which are not legal on the street in most areas. Dual purpose machines like the dual-sport style are made to go off-road but include features to make them legal and comfortable on the street as well. Each configuration offers either specialised advantage or broad capability, and each design creates a different riding posture. http://www.bnkmoto.com/k-series/

Slippers are a kind of shoes. The heel is empty, and only the front has a toe. Most of them are flat bottoms. The material is often quite light and soft leather, plastic, cloth and so on. The types of slippers are distinguished according to the wearing occasion and performance purpose. For example, beach slippers are not made of cloth, but plastic. This is for the sake of being waterproof and easy to clean. The toe type is also specially designed. It is often called pinch slippers, which is what we call flip flops. http://www.jerryfootprint.com/slipper/

In construction, there are three main types of compactor: the plate, the rammer, and the road roller. The roller type compactors are used for compacting crushed rock as the base layer underneath concrete or stone foundations or slabs. The plate compactor, vibrating plate, or tamper, has a large vibrating baseplate and is suited for creating a level grade, while the rammer compactor has a smaller foot. The rammer, or trench rammer, is mainly used to compact the backfill in narrow trenches for water or gas supply pipes etc. http://www.jianermachine.com/road-construction-machinery/plate-compactor/

Because of its good plasticity, it can better meet the requirements of various architectural shapes, but compared with the performance of service life, beauty and durability, color steel corrugated board is better. Corrugated machine is a machine that presses the base paper into corrugated shape through the corrugated wheel on it. It is an important part of corrugated board production line. http://www.justucorrugator.com/corrugated-machine/

In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Dredging is carried out in many different locations and for many different purposes, but the main objectives are usually to recover material of value or use, or to create a greater depth of water. Dredges have been classified as suction or mechanical. Dredging has significant environmental impacts http://www.kedadredger.com/dredger/

Very high speed centrifuges and ultracentrifuges able to provide very high accelerations can separate fine particles down to the nano-scale, and molecules of different masses. Large centrifuges are used to simulate high gravity or acceleration environments (for example, high-G training for test pilots). Medium-sized centrifuges are used in washing machines and at some swimming pools to draw water out of fabrics. Gas centrifuges are used for isotope separation, such as to enrich nuclear fuel for fissile isotopes. http://www.laboratory-centrifuge.com/high-speed-centrifuge/

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. http://www.lxheattransfer.com/heat-exchanger/

The first known case was identified in Wuhan, China, in December 2019. The disease has since spread worldwide, leading to the ongoing COVID-19 pandemic. Symptoms of COVID‑19 are variable, but often include fever, cough, headache, fatigue, breathing difficulties, loss of smell, and loss of taste.
