accuracy of the test data.Easy to operateBecause professional preparations such as "Reagent preparation", "specimen centrifugation", and "System Quality Control" are saved, general staff can operate the instrument.Low Temperature EnvironmentBecause the reagent has a short reaction time (25 seconds) with serum and the system adopts solid phase enzymatic method, the instrument can be used normally in a low t

3140: [Hnoi2013] DisinfectionDescriptionLittle T, who recently worked in a biology lab, is in big trouble.Due to the recent upgrade of the laboratory, his sub-test dish is a cuboid with a size of A*b*c,a, B, and C as positive integers. For the convenience of the experiment, it is divided into a*b*c units of cube area, each unit cube sizeFor 1*1*1. Use (i,j,k) to identify a unit cube, 1≤i≤a,1≤j≤b,1≤k≤c. The experiment dish has been out of use for a long time, and now little T is being asked by th

Xiao Hong once bought n (n 2. there are 16 solutions, and only one of them is toxic. This toxic solution will change color when mixed with another reagent A, while other non-toxic solutions will not change color when mixed with. It is known that an experim

The higher the temperature, the greater the volatility, the World Health Organization under the International Agency for Cancer research as a kind of human carcinogens."Experiment Two"Does the cell phone shell emit pungent odor is formaldehyde?Myth: Some of the phone shells purchased on the market do emit a strong pungent odor.

fully following the previous procedure. PCR is a devil! Many people feel this way. This is just a simple example. If a reagent only reduces the effective amount, you need to increase the dosage. If harmful substances are generated after deterioration, I am afraid it is time to change the reagent. If the device reading is drifting, you must correct it. In short, if a problem occurs, find the cause. "exact"

adopted. In addition, S3C2410A is in the electromagnetic flow meter system.As a high-end application research, the system adopts modular design method in hardware, which improves the Application and Research Level of electromagnetic flow meter and reduces the design difficulty. Through system testing, this intelligent meter can be connected with industrial automation sensors to form a flow measurement control system, which can be widely used for the Flow Measurement and Control of various indus

The reason is that when initializing the Comboboxcell binding a series of values, but the real assignment is given a value that is not in that range of values, so I reported this errorIn the development of the problem will inevitably be due to the problem of data, in order not to let the system collapse, it is necessary to deal with this error messageBut how do you catch and handle this anomaly?I don't know how to capture it, but I know DataGridView already has an event that handles data errors,

Children's Vaccine is renamed againLw56102Http://www.jkzgr.net/jiankangqianyan/864.html Since Andrew Wakefield published an article in the Journal of the journal, in 1998, that the vaccination against children may cause autism and enteritis, it has been continuously affected throughout the world. Although Andrew Wakefield himself and the notorious Article have been repeatedly proved to be forged, the article published by Wakefield himself has commercial interests, it is to promote a

Pesticide Residues on fruits and vegetables have always been a problem for consumers. Traditional methods to remove pesticide residues are nothing more than water, rice washing water, and water cleaning. Later, there were some fruit and vegetable cleaning agents similar to detergent on the market, one or two drops of water can also be used to remove pesticides during dish washing. Using ultrasound to clean fruits and vegetables is another method. In some professional food processing enterprises,

/*Test Instructions: There are n chemical agents, the capacity of the AI, given N and their capacity. There are two types of operations available: 1. Choose a potion to change its capacity to 2*ai 2. Select a medicament to change its capacity to AI/2 the minimum number of operands makes each reagent equal in capacity. Problem solving: Find out the number of each number that can be changed by the two operations, using the F array to record the number o

the toxin is detected, no matter how clear your water is, it is not good for fish.the existence of the toxin indicates that the nitrification system has not been established and sound, water has not been raised, the real good water toxin of fish farming indicators should be zero. The determination of the toxin index of water with the naked eye is not visible, it must be detected using a test fluid. Water quality toxin detection reagent I think it is

phosphoric acid ( English:phosphoric acid) or called orthophosphoric acid (orthophosphoric acid), chemical type H3PO4 , is a common inorganic acid, non-volatile, easy decomposition, almost no oxidation. With acid, is ternary medium acid, its acidity than hydrochloric acid, sulfuric acid, nitric acid is weak, but than acetic acid, boric acid and other strong. It can be obtained by dissolving the phosphorus pentoxide in hot water. The orthophosphoric acid industry uses sulfuric acid to treat apati

fruit sugar has been removed.Vi. "Examples" of false positivesThe second example is a medical FAQ that is closely related to real life.The incidence of a disease is known to be 0.001, which means that 1 of the 1000 people are ill. A reagent can be used to test whether a patient is ill, its accuracy is 0.99, that is, in cases where the patient does get sick, 99% of it may appear positive. Its false positive rate is 5%, that is, in cases where the pati
