COVID 19 Analytical Test

The PCR analytical test (Polymerase Chain Reaction or Polymerase Chain Reaction) has become a fundamental tool to rigorously establish the scope of the SARS-CoV-2 virus pandemic, due to its reliability and high sensitivity, where to purchase lateral flow tests for travel.

It is a molecular biology laboratory tenique that allows us to detect a fragment of the genetic material of the DNA or RNA of a pathogen.

Using this tenique a fragment of the genetic material (RNA nucleic acids) is amified, whi allows detection of the presence of the virus.

The PCR test allows us to determine if a person has the virus or not at a specific time.

It is a very sensitive tenique with a very high specificity.

The PCR test is a tenique created by Kay Mullis in the 1980s, who would later win the Nobel Prize. This tenique makes it possible to reicate the genetic material extracted from a patient's same up to millions of copies, to obtain enough to analyze and aieve a highly reliable result. This quality of amification means that it is also used in obtaining a diagnosis, paternity test, forensic analysis, etc.

The cycle of a PCR test consists of 4 steps:

1. Obtain the same from the patient. It consists of inserting a swab (stick) through the patient's nasopharyngeal route to take the same, in the case of coronavirus. This swab is inserted into a tube with its corresponding code. Saliva extraction can also be done.

2. Extract the genetic material. Through various specific teniques, in this case RNA. Viruses inject their genetic material into cells. For this reason, the RNA of the virus must be released from the infected cell and from the rest of the cellular components.

3. Performance of the PCR tenique. It is the polymerase protein and consists of making an enlargement of millions of copies to detect if the virus is present.

4. Identify the virus by amifying specifically. Specific oligonucleotides for SARS-CoV-2 genome sequences are used to determine the presence of the genes. Specific fluorescent probes for the amified regions are included in the same reaction. The emitted fluorescence is detected at the same time the test is performed thanks to more sophisticated PCR equipment known as real-time PCR equipment. If fluorescence emission from all three fluororomes is detected in the same, it is positive. Otherwise, it shows it as negative.

Расчет высокопрочных болтов на растяжение

Особенности расчета на прочность элементов, ослабленных отверстиями под высокопрочные болты:
При статической нагрузке, если ослабление менее 15 °/о, расчет ведется по площади брутто А, а если ослабление больше 15 %—по условной площади Лусл = 1,18 Ап.

Монтажные стыки

Монтажные стыки делают при невозможности транспортирования элементов в целом виде.
Монтажные стыки для удобства сборки устраивают универсальными: все прокатные элементы балки соединяют в одном сечении.

Проверка прочности

Проверка прочности сечения на опоре балки по касательным напряжениям:
Балочной клеткой называется система перекрестных балок, предназначенная для опирания настила при устройстве перекрытия над какой-либо площадью.
