Egg shells increase body price

In daily life, chickens, ducks, geese, quails, and other poultry or rare bird eggshells are generally discarded by people as waste products. If they are collected and processed into handicrafts, they are worth a hundredfold. Now introduce three eggshell crafts production methods: First, the ordinary egg: choose bright and clean, Zhou Zheng, crack-free eggs, with a cone needle in the egg shell tie a hole, the hole is located in the more rounded end, or selected in the painting covered Parts. Use a syringe to slowly inject air into the shell, pull out the syringe, and remove the egg white and egg yolk. Repeat this until it is exhausted. Use a syringe to inject water into the eggshell, then drain it, repeatedly, and wash the eggshell. Wash and dry the shell, take a little gypsum powder to block the hole, dry and use a fine sandpaper to polish. Then paints on the surface of egg shells with landscapes, animals, flowers, and the like. This is roughly the same as painting on paper. It means the tip of a pen and practice makes perfect. Then add a mahogany seat and place the egg on the shelf. Serve. Second, the egg pendant: egg pendant is one of the popular Christmas gifts in Western countries. The processing method is similar to the general egg processing method. The difference is that when the evacuation, two symmetrical holes are drilled, air is injected from one hole, and the egg liquid flows out from the other hole. After the drawing is completed, a small stick and a white latex are affixed with silk thread, and the large head of the egg shell is pulled in from the hole, and the thread is straightened, and the thin stick naturally traverses inside the egg shell. Then string a small bead on the thread. Another eyelet is threaded on the same string and the pendant in the egg is made. It's even more interesting if you're strung together with a few pendants and made into a string. Third, the carved egg: Select, evacuation, cleaning, blocking the hole with the law, and then made in accordance with the following process: the paraffin melting on the melting paraffin, depicting a pattern on the egg shell, pay attention to the need to retain the eggshell where the wax coating, Leave blanks where you do not want to keep. After the wax is cooled, the eggshell is immersed in rice vinegar for 6-8 hours. The non-waxed portion is dissolved in rice vinegar, and the waxed portion remains as it is. Remove the eggshell from rice vinegar, rinse with water, and dissolve the paraffin in warm water at 60Â°C. The pattern on the eggshell is revealed. Carved eggshells, and then put on color, it has become beautiful, do not have fun carving eggs. China Agricultural Network Editor
Urine Analyzer
Urine analyzer is an automated instrument for determining certain chemical components in urine. It is an important tool for automated urine inspection in medical laboratories. This instrument has the advantages of simple and fast operation. However, improper use of urine analyzers and many intermediate links and influencing factors directly affect the accuracy of automated analysis results, which will not only cause errors in experimental results, but even delay diagnosis. Therefore, operators are required to understand the principles, performance and precautions of automated instruments. And the knowledge of influencing factors and other aspects are fully understood, and the correct use of automated instruments can make the results obtained by the urine analyzer more reliable and accurate.
application
In the 1950s, a single dry chemical test strip method was used to measure protein and glucose in urine, and the changes in the color of the test strip were observed with the naked eye and compared with the standard plate to obtain the corresponding values. In the 1980s, due to the high development and widespread use of computer technology, automated urine analyzers also developed rapidly, gradually developing from semi-automatic to fully-automated. Urine analyzers are often divided into two categories according to the test items: â‘ 8-11 screening combined urine test strips mainly used for newly diagnosed patients and health examinations. The eight test items included protein, glucose, PH, ketone bodies, bilirubin, urobilinogen, red blood cells (occult blood) and nitrite; in addition to the above eight tests, urine leukocyte test was added to the nine test items. On the basis of 9 of the 10 urine analyzer testing items, the urine specific density test was added. 11 testing items have added vitamin C testing. â‘¡It is mainly used for the observation of the curative effect of the diagnosed diseases, such as the combination test strip of PH, protein and occult blood (red blood cells) for kidney disease; the combination test strip of PH, sugar and ketone body for diabetes; the combination of bilirubin and urobilinogen for liver disease test tape.
principle
This type of instrument is generally controlled by a microcomputer, and the color change on the test strip is measured semi-quantitatively by using a spherical integrator to receive dual-wavelength reflected light. There are several reagent pads containing various reagents on the reagent strip, each of which reacts independently with the corresponding components in the urine, and displays different colors. The depth of the color is proportional to a certain component in the urine, and there is another in the reagent strip" Compensation pad", as the urine background color, compensates for the errors caused by colored urine and instrument changes.
Put the reagent strip with urine adsorbed in the colorimetric tank of the instrument, and the various reagent pads that have produced chemical reactions on the reagent strip are illuminated by the light source, and the reflected light is received by the spherical analyzer, and the photocell of the spherical analyzer is reflected. Irradiate with dual-wavelength light (measurement light passing through the filter and a reference light), and the selection of each wavelength is determined by the detection item.
The instrument automatically calculates the reflectance according to the following formula, and then compares it with the standard curve, and automatically finds and prints the corresponding results of various components. If the content of a certain component in the urine is high, the reflected light of the corresponding reagent pad is dark, otherwise it is strong.
Reflectance fraction: R(%)=Tm.Cs/TsCmÃ—100%
In the formula, R(%) is the reflectivity; Tm is the reflection intensity of the reagent pad to the measurement wavelength; Ts is the reflection intensity of the reagent pad to the reference wavelength; Cm is the reflection intensity of the calibration pad to the measurement defect length; Cs is the calibration pair. Reflection intensity at the reference wavelength.
