The story of transmitting information from ancient times to the present

Painting and photography were both visual arts, and this was one of their connections. Both of them used composition, space, and color to record the feelings of objective objects. They were both in the aesthetic category and could improve aesthetic taste and ability. They had similar elements and criteria in the creation of planar art. For example, according to the visual effect of beauty, they were arranged and combined in a rational and logical way, involving color composition, planar composition, and three-dimensional composition. However, there were differences between painting and photography. The history of painting can be traced back to the primitive Stone Age, while the history of photography can be traced back to the mid-19th century when photography was introduced to China. Painting required pen, ink, paper, inkstone, and other equipment, while photography required cameras, flashlights, mirrors, and other equipment. In the process of creation, the painter could freely create, while the object faced by the photographer was usually fleeting. This made the photography work sometimes seem rigid and simple. In addition to the two-dimensional, color, and three-dimensional composition of excellent photography works, the composition of thinking was also very important. Drawing allowed the artist to observe the world through the eyes of the artist, but drawing from a photograph might be a little dull because it was difficult to perceive the volume of the object in reality, as well as the movement and power of the object's form. These differences and connections were also applicable to the paintings and photographs of contemporary primary school students. Primary school students could use more imagination to create when painting, while photography relied more on the actual scenes and moments captured. But whether it was painting or photography, it could show the primary school students 'observation and understanding of the world. It was their way of expressing themselves and showing their creativity. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

For npn-type triode, the current flowing from the base to the transmitter is positively biased (the transmitter junction is positively biased), and the current flowing from the collector to the transmitter is a large current, and the collector is reversed at this time; For pnb-type triode, the current flowing from the transmitter to the base is positively biased (the transmitter junction is positively biased), and the current flowing from the transmitter to the collector is a large current, and the collector is reversed at this time. In the circuit design, it was achieved by reasonably setting the voltage of each pole. The positive bias was that the voltage of P was higher than the voltage of N, and the reverse bias was that the voltage of P was lower than the voltage of N. When the triode was in the amplifying circuit, it could ensure that the positive bias of the emitting pole could be achieved while the reverse bias of the collector could be achieved. For example, when the voltage applied to the emitting junction of the triode was greater than the on-state voltage of the P-N junction, and it was at a certain appropriate value, the emitting junction of the triode would be biased forward, the collector junction would be biased backward, and the collector would be biased backward. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a model biosafety emergency drill plan: I. General principles This plan is specially formulated to strengthen biosafety management, improve the emergency response ability to deal with sudden biosafety incidents, and ensure the safety of personnel and the surrounding environment. Second, the scope of application This protocol is applicable to all kinds of biosafety incidents that occur in the laboratory (or unit), including but not limited to biosafety related incidents such as spilling of infectious materials, failure of biosafety cabinets, infection of personnel, laboratory fires, etc. III. Organization and responsibilities 1. emergency headquarters The person in charge of the laboratory (or unit) shall act as the chief commander, responsible for overall coordination and command of the emergency drill, including the formulation of the drill plan, the determination of the drill target, and the command of emergency response actions. 2. emergency response team It was composed of biosafety specialists, relevant technical personnel, and department heads. Be responsible for the specific implementation of emergency drills and emergency response work, such as on-site handling of biosafety incidents, operation of emergency equipment, etc. 3. Emergency Contact Group He was responsible for communicating with the higher authorities, surrounding communities, and relevant cooperative departments, and timely conveying information, needs, and instructions. 4. emergency support group Be responsible for the preparation, allocation, and guarantee of emergency supplies, and ensure the adequate supply of protective articles, disinfection articles, emergency equipment, and other materials required for emergency. IV. Emergency response procedures 1. event report After a biosafety incident occurs, relevant personnel at the scene should immediately report the incident to the emergency command center. The report should cover key information such as the time and place of the incident, the biological substances involved, casualties or exposure. 2.应急响应 After receiving the report, the emergency command center quickly activated the emergency plan and informed the emergency team, emergency contact group, and other relevant personnel. 5. Drill content 1. Biosafety training Before the drill, arrange for biosafety experts or senior personnel to conduct biosafety knowledge training for all personnel participating in the drill. The training content included the basic knowledge of biosafety, the biosafety operation procedures of the unit, the prevention of biosafety accidents, and the handling of common accidents. 2. Simulate the biosafety incident handling drill (1) Spilling of infectious materials For example, the simulation of the spilling of the culture fluid for the cultivation of bacteria. After the staff found the overflow, they immediately carried out preliminary treatment on the spot, such as covering the overflow with disinfectant paper towels, pouring an appropriate amount of disinfectant (such as disinfectant containing disinfectant) from the periphery to the center, and expanding the disinfection area, while avoiding contact with the overflow. The rest of the personnel evacuated according to the emergency plan and set up a warning area to prevent unrelated personnel from entering. After that, cleaning and disinfection personnel wearing protective equipment (such as protective clothing, masks, goggles, gloves, shoe covers, etc.) would enter the site, collect the spilled and absorbed substances into special medical waste garbage bags, seal and mark them properly, and thoroughly clean and disinfect the site again. (2) Personal injury (exposure to biohazard) incidents Simulate the situation where a person is injured or exposed while operating a biohazard. The injured personnel should stop working immediately and carry out preliminary self-protection treatment on the spot (such as taking off contaminated clothes, washing exposed skin, etc.), and report to colleagues or superiors at the same time. The emergency response team responded quickly, providing further medical assistance, risk assessment, and recording and follow-up of exposure incidents according to the prescribed procedures. (3) Biosafety Cabinet Malfunction Event Simulate the failure of the biosafety cabinet during use, such as abnormal airflow. After the operator discovered it, he immediately stopped the operation and placed the biological materials that were being processed properly away from the faulty equipment. Then, it would be reported to the emergency command center, and professional technicians would assess and repair the fault. Before the fault was eliminated, the use of relevant areas or equipment would be restricted. 6. Drill Flow 1. preparatory phase (1) Decide the time, location, and participants of the drill. (2) Prepare the materials and equipment needed for the drill, such as simulated biohazard, protective equipment, disinfection equipment, emergency equipment, etc. (3) Train the participants in advance to familiarize them with the drill process and their respective responsibilities. 2. Drill implementation stage (1) Carry out the drill operation according to the set biosafety incident scene, and each emergency team and personnel will carry out the work according to the division of responsibilities. (2) During the drill, observe and record the implementation of each link, including the operation specifications of the personnel, the timely response to the emergency, and the coordination between the teams. 3.
