The efficacy and function of mushrooms and edible methods

The role and efficacy of mushrooms

Shiitake mushrooms have high protein, low fat, polysaccharides, a variety of amino acids and a variety of vitamins.

1. Improve the body's immune function: lentinan can increase the phagocytic function of mouse peritoneal macrophages, can also promote the production of T lymphocytes, and increase the killing activity of T lymphocytes;

2. Anti-aging: The water extract of shiitake mushroom has a scavenging effect on hydrogen peroxide and a certain elimination effect on hydrogen peroxide in the body;

3. Anti-cancer and anti-cancer: The mushroom caps contain ribonucleic acid with a double-stranded structure. After entering the human body, they will produce interferons with anti-cancer effects.

4. Lower blood pressure, blood fat, cholesterol: mushrooms contain purine, choline, tyrosine, oxidase and certain nucleic acid substances, can play a role in lowering blood pressure, cholesterol, blood fat, but also to prevent atherosclerosis Cirrhosis and other diseases.

5. Mushrooms also play a therapeutic role in diabetes, tuberculosis, infectious hepatitis, neuritis, etc., and can also be used for indigestion, constipation and so on.

The practice of mushrooms

First, the practice of mushrooms stuffed with tofu

Ingredients: 300 grams of tofu, 3 mushrooms, proper amount of starch: proper amount of soy sauce, amount of sugar, amount of sesame oil

practice:

1 Cut the tofu into small cubes and hollow out in the middle;

2 Wash the shredded mushrooms, chop the mustard, add the seasonings and mix the starch to make the filling;

3 Fill the tofu center with the stuffing, place it on a saucer, steam it, and topped with soy sauce and sesame oil.

Sodium Hyaluronate

Sodium Hyaluronate is very important for skin because it improves moisturization, maintains skin resilience, and reduces damage in the lower part of skin when the skin is damaged. It also acts like lubricant by causing collagen, a main constituent of skin, to move smoothly in between cells. 


 

But from the age of 25, Sodium Hyaluronate in human body will lose gradually, only remaining 65% of young skin at the age of 30, only 25% of young skin at the age of 50. 


 

With the increase of the age and the loss of Sodium Hyaluronate, the skin will lose elasticity and luster, aging, wrinkles and relaxation will be generated gradually. 

Sodium HyaluronateHA powder CAS NO. 9004-90-1

 

Sodium Hyaluronate is so water-friendly and it has functions of the best moisturizing factor and prevents diseases such as skin infections by preventing the penetration of external substances such as bacteria.

Therefore, it is regarded as an ideal "natural moisturizer" factor and widely used in غير مجاز مي باشدmetics that suitable for different skins, climates and environments.

High molecular Sodium Hyaluronate can be formed breathable film on the surface of the skin, help the skin to lock moisture, and to prevent the invasion of bacteria, dust and ultraviolet, so that to protect the skin from damage.

Low molecular Sodium Hyaluronate, which is designed for better skin penetration, can penetrate into the dermis quickly, dilated capillaries slightly, promote blood circulation and metabolism, and so it has function of eliminating wrinkles, increasing skin elasticity and preventing skin aging.

The story of Li Shizhen and pangolins

According to Tao Hongjing’s record in the book “Ben Cao Jing Ji”, pangolin is a kind of anteater. It can “land energy”, make a landing in the middle of the day, open the scales like a dead animal, and attract ants into A, that is, close into the water and open a ant. All of them floated, surrounded and eaten.” Is the pangolin's habits really the way? To clarify this issue, Li Shizhen followed the hunter into the deep forests and old forests, performed pangolin dissection, and found that the stomach of the animal was indeed full of undigested Ants proved that the book was correct. However, Li Shizhen found that pangolins were not scavenged by ants, but "usually tempted by insects to eat ants." He revised the misstatement of this point in this cursive. At the same time, he collected the medicinal value of the pangolins in the private sector and recorded a jingle of "Pangolin, the king does not stay, the woman eats a long milk flow."

Analysis of Misunderstanding of Centrifugal Pumps in Use

1. High lift pump for pumping with low lift Many operators think that the lower the pumping head, the smaller the motor load. In the misunderstanding of this misunderstanding, when choosing a water pump, the head of the pump is often selected very high. In fact, for the centrifugal pump, when the pump model is determined, the power consumption is proportional to the actual flow of the pump. The flow of the pump will decrease with the increase of the head, so the higher the lift, the smaller the flow and the smaller the power consumption. Conversely, the lower the head, the greater the flow and the greater the power consumed. Therefore, in order to prevent motor overload, it is generally required that the pump's actual pumping head should not be less than 60% of the nominal head. Therefore, when the high head is used for pumping the pump with too low lift, the motor is easily overloaded and generates heat. In severe cases, the motor can be burned. If it is used in emergency, it must be installed on the outlet pipe to adjust the amount of water out of the gate valve (or a small outlet with a small object such as wood) to reduce the flow and prevent the motor from overloading. Pay attention to the temperature rise of the motor. If the motor is found to be overheated, turn off the flow at the outlet or turn off the power immediately. This is also easy to misunderstand. Some operators think that blocking the outlet and forcing a reduction in traffic will increase the motor load. In fact, on the contrary, regular high-power centrifugal pump irrigation units are equipped with gate valves on the outlet pipe. In order to reduce the motor load when the unit is started, the gate valve should be closed first. This is the reason for gradually opening the gate valve after the motor is started.

2. Large-diameter pump with small water pumping Many operators think that this can increase the actual head, in fact, the actual head of the pump = total head ~ loss head. When the pump model is determined, the total head is constant; the loss head mainly comes from the pipe resistance, the smaller the pipe diameter, the greater the resistance is, so the greater the loss head, so after reducing the pipe diameter, the actual lift of the pump can not be increased. Instead, it will decrease, leading to a drop in pump efficiency. Similarly, when a small-diameter pump uses a large pipe to pump water, it will not reduce the actual head of the pump. Instead, it will reduce the loss head due to a reduction in the resistance of the pipe, which will increase the actual lift. It is also considered that the small-diameter pumps will inevitably greatly increase the motor load when they pump water. They believe that after the pipe diameter is increased, the water in the outlet pipe will have a large pressure on the pump impeller, which will greatly increase the motor load. As everyone knows, the size of the liquid pressure is only related to the height of the head, and has nothing to do with the size of the cross-sectional area of ​​the water pipe. As long as the head is constant, the impeller size of the water pump is constant. Regardless of the diameter, the pressure acting on the impeller is constant. Only after the pipe diameter increases, the flow resistance will decrease, and the flow will increase, and the power consumption will also increase appropriately. But as long as the rated head range, regardless of how to increase the diameter of the pump can work properly, but also can reduce the loss of pipelines, improve the pump efficiency.

3. When installing the water inlet pipe, the horizontal section may be horizontal or upward. This will cause air to collect in the water inlet pipe, reduce the degree of vacuum of the water pipe and the water pump, reduce the water absorption of the pump, and reduce the water output. The correct approach is: The horizontal section should be slightly inclined to the direction of the water source, should not be horizontal, but not upturned.

4. The elbows used in the inlet pipe are many if there are many elbows used in the inlet pipe, which will increase the local flow resistance. And the elbow should be turned in the vertical direction, not allowed to turn in the horizontal direction, so as not to gather air.

5. The water pump inlet is directly connected to the elbow, which causes uneven distribution of the water flow through the elbow into the impeller. When the diameter of the inlet pipe is larger than the inlet of the pump, an eccentric reducer should be installed. Eccentric reducer tube is to be mounted on the flat surface, and the inclined surface is mounted on the bottom. Otherwise, the air will gather, the amount of water will be reduced or the water will not be able to be pumped, and there will be a crash. If the inlet pipe and the water pump inlet diameter are equal, a straight pipe shall be added between the inlet of the pump and the elbow. The length of the straight pipe shall not be less than 2 to 3 times the diameter of the water pipe.

6. The bottom section of the water inlet pipe with bottom valve is not vertical. If it is installed in this way, the valve cannot be closed by itself, causing water leakage. The correct installation method is: The inlet pipe is equipped with a bottom valve, and the bottom section is preferably vertical. If it cannot be installed vertically due to topographic conditions, the angle between the axis of the water pipe and the horizontal plane should be above 60°.

7. The inlet of the inlet pipe is not in the correct position. (1) The inlet of the inlet pipe is less than the diameter of the inlet of the inlet and the bottom of the pool. If there is sediment and other dirt at the bottom of the tank, when the distance from the water inlet to the bottom of the tank is less than 1.5 times of the diameter, it will cause poor water intake or infiltration of muddy debris and block the water inlet.

(2) When the depth of the inlet of the inlet pipe is insufficient, this will cause vortexes on the water surface around the inlet pipe, affecting the inlet water and reducing the amount of water discharged. The correct installation method is: the water depth of small and medium-sized pumps shall not be less than 300-600mm, and the large-sized water pumps shall not be less than 600-1000mm.

8. The outlet pipe outlet is above the normal water level in the outlet basin. If the outlet outlet is above the normal water level in the outlet basin, although the lift of the pump is increased, the flow rate is reduced. If due to topographic conditions, the water outlet must be higher than the water level of the water tank, then elbows and short pipes should be installed at the nozzle to make the water pipe a siphon type and reduce the outlet height.

Door and window hardware is the core of the entire door and window

Door and window hardware is the core of the entire door and window

At present, most consumers lack knowledge of door and window hardware when purchasing doors and windows, lacking accurate judgment and satisfaction. However, in the doors and windows, the role of hardware and accessories is an indispensable key component. It can be said that hardware and accessories are the most used door and window components. Its quality is related to the service life of doors and windows and has a direct impact. Induction quality of doors and windows.

It can be said that the door and window hardware is the core of the entire door and window, including handles, locks, hinges, etc., each component has a major role.

The key to the service life of doors and windows lies in the maintenance of 'hardware'. The key to the maintenance of door and window hardware lies in the following four points: 1. Stainless steel handles and stainless steel other 'hardware' can be scrubbed with brighteners to increase light.

2, hinges, hanging wheels, casters and other moving parts in the long-term movement may be due to the adhesion of dust and reduce the function, every one and a half months to place one or two drops of oil can adhere to its smooth.

3, pay special attention to handle the direction of rotation and avoid using dead force. In particular, children should be taught not to hung on the doorknobs, which is both prone to danger and may endanger the inner door.

4. When the lock cylinder is not sensitive to rotation, a small amount of black powder may be scraped from the pencil lead and lightly blown into the lock hole. This is because the graphite component between them is an excellent solid lubricant. Do not instill lubricating oil, because it will be easier to adhere dust.

Split electromagnetic flow meter daily inspection guide

The purpose of daily inspection of split electromagnetic flowmeters is to ensure or prove that they are operating under controlled conditions. There are two types of routine inspections, on-line inspection and off-line inspection, mainly to verify whether the flow measurement of the electromagnetic flowmeter meets and maintains the expected measurement requirements.

The electromagnetic flow meter is mainly used in industrial applications for flow control, and the measured fluids are mostly corrosive and abrasive. In practical applications, the failure of the electromagnetic flowmeter is mostly caused by corrosion leakage, insulation degradation, electrode fouling or adhesion of foreign substances.

The traditional periodic maintenance check of the electromagnetic flowmeter is to sweep and inspect the flow sensor discharge line and then perform flow calibration. In order to reduce the flow sensor unloading the damage lining from the pipeline, first determine whether the insulation resistance is abnormal in the pipeline or not, and then decide whether to remove the pipeline inspection or real flow flow calibration in the next step. General conditions (real implementation of ISO9001 quality management system) The general inspection methods of the company are: (1) 1/3 for on-line inspections; (2) 1/3 for removing pipelines for inspection after cleaning parts; (3) ), 1/3 off-line for flow calibration.

One of the specific operating modes of split magnetic flowmeters can be a comprehensive inspection of electromagnetic flowmeters every year. The inspection contents are: appearance inspection, converter characteristic test, calibration of measured values, measurement of voltage of each part, measurement of insulation resistance, confirmation of circuits, etc. When measuring and adjusting the instrument, due to the zero drift, it is very important to adjust the zero point (“On-line zero adjustment” must stop the measured medium from flowing, which is not easy to do). Therefore, the online inspection often omits the inspection including the operation of the sensor, and only the calibration of the converter is performed, so that the comparison of the on-line inspection result with the historical data confirms whether the instrument continues to be used, repaired or updated, and the sensor is measured according to the measured insulation resistance of the excitation coil. The degree of deterioration is determined to be updated or not.

Split-type electromagnetic flowmeter specific operation of the second through online inspection to verify whether the electromagnetic flowmeter abnormal phenomenon. Check the flow sensor and converter individually for pipelines that cannot stop the flow of media, test the converter with analog signal and other general-purpose instruments with high calibration accuracy (this depends on the accuracy of the analog signal), and the sensor check with the test electrode. Wetted resistance, check the excitation coil including the insulation resistance and copper resistance of the excitation connection cable, as well as the indirect method of checking the excitation current output by the converter and checking the strength of the magnetic field. For pipelines that can stop the flow conditions of the media, they can be accessed from the entry holes that are preset near the sensors, checking the levels and lining dirt/deposition conditions and cleaning.

Split-type electromagnetic flowmeter Check contents Check the electromagnetic flowmeter. In addition to the zero-point check, separate the flow sensor, transducer, and connection cable.

1. Zero check of the whole machine The technical requirement of the zero check is that the measuring tube of the flow sensor is full of liquid and there is no flow. This would give up the zero check and adjustment of the whole machine at the site of many enterprises, but it can be turned to the converter. Make a separate zero check and adjustment. Technically speaking, this must have practical significance after the sensor is inspected and the insulation resistance of the sensor's excitation circuit and signal circuit is normal (including cables). Otherwise, the whole machine cannot operate normally. Usually the converter's single zero is negative and the value is very small; if its absolute value is greater than 5% of full scale, it needs to be checked first, and then adjusted after confirming the reason. Under normal circumstances, the zero point of the electromagnetic flowmeter and the individual zero difference of the converter is less than 1%. Many of the zero difference values ​​above 5% are caused by incorrect zeroing operations by the user in the event of a poorly closed pipe valve.

2. Checking the Connection Cable This check is to check the conduction and insulation resistance of each core of the signal line and the excitation line, and check whether the grounding of each shielding layer is in good condition.

3, converter check The inspection content is to use the general instrument and the flow meter model matching analog signal device instead of the sensor to provide the flow signal for zero adjustment and calibration. Calibration includes zero check and adjustment, set value check, excitation current measurement, current/frequency output check, etc. It should be noted that the inspection item must be compared with the previous inspection value (or factory value) and whether there is any change or change in the original metering requirement.

4. Flow sensor inspection The inspection content is: indirect evaluation of whether the magnetic field strength is changed by checking the excitation coil and checking the excitation current measured by the converter; measuring the electrode resistance to evaluate the contamination of the electrode surface and the lining adhesion layer Condition; Check the insulation resistance of each part to determine the degree of component degradation to assess whether it will introduce interference. For pipelines that can stop media flow conditions, the thickness of the electrode and liner adhering layer can be observed and measured to estimate the change in flow values ​​introduced by the change in flow area before and after cleaning the adhering layer.

(1) Measure the coil resistance of the excitation coil. Measure the coil resistance with a high-accuracy digital multimeter or Wheatstone bridge. If necessary, make a temperature coefficient correction and compare it with the instrument file value. Verify that the coil is conducting well and there is no short circuit between the turns.

(2) Checking the Insulation Resistance of the Excitation Coil The insulation coil of the excitation coil and its connection terminals are dampened after the dampening of the excitation circuit to the ground. It is possible to introduce the excitation signal into the flow signal transmission circuit so that the electrode adds a large insulation resistance and signal resistance to the excitation voltage. The partial pressure, forming a large common-mode interference signal. When this disturbing signal exceeds the suppressing ability of the converter preamplifier, the zero point of the converter is shifted. When the drop in insulation resistance is not very serious, this phenomenon is not easily noticeable when the instrument is running. Except for IP68 terminal box, due to carelessness in practice, the terminal box is not sealed into the moisture, and the terminal insulation resistance drops below 5-6 MΩ, which is likely to cause failure. Blow dry the terminal, usually the fault can be eliminated.

(3) Checking the Electrode Resistance The flow resistance of the electrode flow sensor should be measured immediately after the new instrument is commissioned and recorded. After each maintenance measurement once, analysis and comparison of these data can help determine the cause of the instrument failure.

The contact resistance of the electrode with the liquid depends on the measured liquid conductivity of the contact surface. There are significant differences in the measured resistance of different media. The electrode contact resistance can be measured by the pointer multimeter when the measuring tube is filled with liquid and the resistance between each electrode terminal and ground is measured. Experience has shown that the difference between the contact resistance values ​​of the two electrodes should be less than 10% to 20%, otherwise it indicates a fault.

If there is a difference between the measured resistance of the electrode solution and the original measurement, the reasons are: a. The coverage of the two-electrode insulating adhesion layer is inconsistent or the insulation resistance of one of the electrode signal loops decreases; b. The increase of the resistance value is the insulation of the electrode surface. Layer coverage; c, reduced resistance value is a conductive deposition layer attached to the surface of the electrode near the electrode or electrode assembly (such as insulation ring) insulation down. Although failures are not sometimes formed, measures should be taken as a precursor to failure.

(4) Measure Polarization Voltage Between Electrode/Liquid The measurement of this voltage will help determine if the electrode is dirty or covered. This may cause a zero-point instability or output-sloshing failure.

(5) Checking insulation between the signal circuit insulation and the excitation circuit/signal circuit The purpose of this check is to evaluate whether or not to introduce interference due to a drop in insulation. When checking the signal circuit, the signal line should be temporarily disconnected from the electrode. Caused by the decrease in insulation, the junction box is not sealed and moisture is entered, and the protective sensor cable is cut off and then moisture-proof.

(6) Check the electrode insulation resistance and lining condition. This inspection is to remove the small-caliber instrument from the pipeline. For the large-caliber instrument, the effusion can be vented and then enter the pipe from the inlet hole. Observe: Dry the lining inner surface with megohmmeter. Test the insulation resistance of the two electrodes to the ground; if the liner has an adhesion layer, it shall be removed and the cleaning cycle shall be determined according to the thickness of the laminate; if the adhesion layer is not thick and the conductivity is the same as the liquid, the additional error of the area change may be ignored; if the adhesion layer conductivity Less than the liquid will produce a positive additional error, and vice versa will produce a negative additional error.

The electrode insulation resistance is generally required to be greater than 100MΩ, and the insulation declines due to the external electrodes and bushes being affected by the external immersion and dampness (using a hot air blower to remove moisture); if the insulation is damaged (such as the intrusion of the etching liquid from the seal), the sensor must be replaced or Return to factory for repair.

Suggestions for the routine inspection of separate electromagnetic flowmeters 1. Formulation of daily inspection specification documents The company shall formulate its own daily inspection work instructions on the basis of implementing the ISO9001 standard and establish a quality management system. Large-scale enterprises may formulate "magnetic flowmeters" Online calibration method "or" electromagnetic flowmeter online calibration specification "to ensure that the use of electromagnetic flowmeter controlled effective.

2. Promotion and application of daily inspection instruments Domestic and foreign special equipments for electromagnetic flowmeter testing and inspection have been developed at home and abroad. The application places of such special instruments have been applied in the water industry and metallurgical and chemical industry, and other conditions. Enterprises with favorable conditions should actively promote their application. . Its development will be dedicated test equipment and portable PC, with the use of: on-site or calibration chamber, a special instrument terminating the other end of the electromagnetic flow converter PC, complete daily inspection test and inspection operations

Analysis of common problems in IHC/ICC experiments

Technically speaking, IHC and ICC experiments are not difficult, however, there are so many variables in each experiment that need to be identified and optimized. If the bad luck, the experimental results are not very good, then we may have to do troubleshooting to see where the problem lies. The following table lists the common problems of the IHC/ICC experiment analyzed by Shanghai Yuan Mu senior technology, and the corresponding countermeasures.

Problem 1: lack of staining Possible Cause Countermeasure Lack of antigen Check protein expression by in situ hybridization.

Due to improper storage, antibodies do not work as stored in the instruction manual. In general, the antibody is aliquoted in small portions, sufficient for a single experiment. Store these antibodies in a manually defrosted refrigerator (-20 to -70 °C) to avoid repeated freezing and thawing.

Primary or secondary antibody inactivation independent test reporting system to assess the usefulness of the reagent.

Insufficient fixation of the tissue Try to increase the fixed time or change the fixative.

Over-fixation of tissue reduces the duration of steps after infiltration or fixation. If infiltration is unavoidable, the antigen is not masked by the antigen retrieval agent.

Primary and secondary antibodies are not compatible with secondary antibodies that interact with primary antibodies. For example, if the primary antibody is from a rabbit, use an anti-rabbit secondary antibody.

The epitope has been altered during fixation or embedding attempts to restore immunoreactivity by various antigen retrieval techniques.

Tissues are embedded at 58°C or below.

Antigen repair does not work to increase the processing time or change the treatment solution.

The reagents are missing or in an incorrect order. Repeat the staining process. Confirm that the correct reagents are used and add them in the correct order.

Question 2: High Background Probable Causes Countermeasures High-titration of antibodies at the concentration of primary or secondary antibodies to determine the concentration of zuijia required to promote the specific responses of primary and secondary antibodies. .

Hydrophobic interactions of antibodies and proteins in tissues reduce the ionic strength (especially monoclonal antibodies) of antibody dilutions.

Non-specific binding of primary or secondary antibodies to tissue uses a blocking step (typically using 1% BSA and 10% normal donkey serum) prior to incubation with the primary antibody. Skim milk powder is also an option.

Nonspecific binding of the secondary antibody uses antibodies with cross-reactive IgG removed.

The tissue dries during the staining process to avoid drying out the tissue.

The background caused by the ionic interaction increases the ionic strength of the diluent.

Question 3: Cell/tissue morphology is destroyed Possible causes Countermeasures Antigen repair methods are too rigorous Experimental conditions are determined based on experience. Immunoreactive tissue sections that can retain tissue morphology and restore antigen are detached from the slide for a fixed period of time. Another fixative is determined empirically.

The tissue section is torn or folded. Re-slice the bubbles under the slice, or ignore the damaged area when analyzing the results.

The difference in resolution of the tissue morphology cuts out thinner tissue sections. Ice crystals may destroy the shape of frozen sections.

Insufficient fixation can cause tissue or cells to be damaged for a fixed period of time during staining. Increase the fixative/tissue ratio. Cut out smaller tissues for more thorough infiltration.

Tissue autolysis leads to staining of necrotic debris for a prolonged period of time and proportion. Consider using crosslinked fixatives.

Problem 4: Improper dyeing Possible cause Countermeasures Improper fixing method Try another fixing agent, or extend the fixing time.

Antigen remediation may improperly try another antigen retrieval condition.

The electrostatic charge of the antigen is changed to try to adjust the pH or cation concentration of the antibody dilution.

Fixed delays cause antigen diffusion to quickly fix tissue. Try cross-linking fixatives instead of organic fixatives.

What are the features of the smart PDU?

Sockets are an indispensable necessities in life nowadays, but people who speak intelligent PDUs are relatively few, let alone their use materials, load power, and service life. Smart people alone are also ignorant of this feature. Understand, then how intelligent PDU embodies intelligence?


First, outside the remote:

The management control information and data information are transmitted through different physical channels, which are independent of each other and do not interfere with each other, and the remote power supply management of the equipment is easily realized. Provides common network tools for the TCP/IP protocol. You can remotely inquire, switch, or restart the power supply of the controlled device through the web interface at any time and anywhere, and reduce the possibility of shutting down the target device due to unexpected errors.

Second, independent control:
