Where is the difference between vacuum cleaners that sell for more than a hundred dollars and those that sell for thousands of dollars?


For many of you, the most important factor to consider when purchasing a vacuum cleaner for the first time is the price.

I struggled with this problem before I used a best vacuum for thick carpetvacuum cleaner; the price of vacuum cleaners on the market varies, from cheap 100 to expensive 4,000 to 5,000; what is the difference?

As a fan of home appliances, I've purchased several vacuum cleaners in the last two years, ranging in price from more than $100 to more than 2,000. Today, we'll go over the differences between these vacuum cleaners at various price points!

Motor

My family's first vacuum cleaner, which cost less than $200, felt good at first because it was easier to use than a broom for hygiene.

However, this seemingly inexpensive vacuum cleaner broke after less than a year, the company does not provide warranty, and I can only replace it with another one.

Later, I discovered that vacuum cleaners in the hundred dollar range use brushed motors, which are extremely inexpensive, costing about twenty dollars for a cheap one.

The brush motor is easily overheated during the working process, reducing the life of the vacuum cleaner and, over time, the natural "strike"!

The thousand dollar grade vacuum cleaner, which typically uses a brushless motor, not only has the advantages of low wear and tear, low energy consumption, durability, and reduced noise.

Suction strength

Suction power is the most important feature of a vacuum cleaner.

In general, if you want to meet the needs of daily household cleaning, the suction power of the vacuum cleaner should be greater than 100AW; however, some vacuum cleaners fall short of this requirement.

However, many businesses will use vacuum (pa) to confuse the concept; in the product details, the suction power is not mentioned, and many partners see tens of thousands of pa who believe the suction power is very strong when, in fact, it is not.

Filtering technology

Some vacuum cleaner filtration devices use sponge filters, which allow dust and hair to accumulate on top of the filter and cause secondary pollution.

I used to use this type of vacuum cleaner with a filter, and every time I cleaned the garbage in the dust bin, I could feel the dust floating in the air, which was a very unpleasant experience.

Functionality

Some vacuum cleaners not only have low suction power, but they also only have a single function, usually only 1-2 brush heads that can only clean the ground waste.

Furthermore, their brush head design is very rough, with some having a large opening at the bottom and no roller brush.

Do a comprehensive medical examination, these 6 check-up items must be done, one can not be saved


What items are necessary to do a comprehensive physical examination?

1, to do a comprehensive physical examination, we need to check the endocrine system, through the endocrine system design can fully reflect the of students' physical and mental health. The endocrine system can be checked, including the three items of blood sugar, glycated hemoglobin and bone density. The normal blood glucose concentration is 80-120 mg%, and if it is not exceeded or below this value, the teacher needs to study the next examination. In addition, glycosylated hemoglobin can effectively reflect the level of blood glucose control management and is used to analyze the ability to determine whether diabetes is present. The middle-aged and elderly society needs to judge the degree of physical health education based on the detection of bone density.

2. Comprehensive examination includes blood system examination, which is generally routine blood examination. The routine blood test can be used to know whether there are blood diseases and to grasp the internal situation in the blood. In addition, changes in the number and morphology of red blood cells, white blood cells, and platelets can help determine the health status of the body.

Digestive system examinations are also essential. Gastroscopy, colonoscopy, abdominal ultrasound, liver function tests, and Helicobacter pylori tests can be performed to understand the health of the digestive system. Colonoscopy, gastroscopy and abdominal ultrasound are best for middle-aged and elderly people, through which they can determine whether there are problems in the stomach. In addition, liver function tests are routinely performed, mainly by the values of glutamic oxalacetic transaminase and glutamic alanine transaminase.

Figure 4. The cardiovascular system is subject to a thorough physical examination, and the health of the heart can be understood through an electrocardiogram. Generally speaking, if you live with frequent symptoms of chest discomfort, dizziness and sometimes discomfort in the precordial region, you need to have a timely ECG examination. ECG examination is an important test for cardiovascular health examination and diagnosis of various cardiac diseases.

5. A comprehensive physical examination needs to involve urinary system examination to understand the health status of the urinary system through routine urine and kidney function tests. The item that needs to be performed for middle-aged and elderly people is urine routine. By analyzing the composition of urine, we can know whether there are diseases in body organs. In addition, kidney function test is mainly through creatinine, uric acid and other values to know. If you have gout symptoms, you need to check the kidney function regularly.

6, respiratory management system is one of the must-check project techniques, through chest X-ray, lung CT, etc., to understand the patient's lung function analysis and other lung health development status, can detect early lung lesions or airway lesions. Especially we frequent smokers need a check respiratory control system to prevent respiratory research diseases.

In order to prolong your life, you need to have regular physical examinations and any physical abnormalities can be treated immediately. Since many diseases are easily treated in the early stages, they are usually difficult to cure in the advanced stages. Therefore, it is recommended to develop a good habit of regular medical check-ups in your life to protect your health.

Hair loss is terrible when you a...

Emotion is an important factor leading to hair loss:

Many people think that good or bad mood is not important, so you are wrong. You must know that keeping a happy mood every day is the basis of good health. Instead, if you leave yourself in negative emotions for a long time, it will increase hair loss, especially common alopecia areata.

What is alopecia areata? Alopecia areata is more common in adolescents, both in men and women. According to the condition of alopecia areata, if all the hair has fallen off, it is called total baldness, and if only the whole body has fallen off, it is called general baldness.

If the hair is on the scalp, some areas are hair loss, loose hair, and mood is an important factor leading to alopecia areata.

So, if everyone wants to avoid hair loss, it is important to keep a happy mood every day.

Frequent scratching of hair is an important factor leading to hair loss:

Among the important factors that cause hair loss, scratching also requires special attention, especially women who like to wear a lot of braids, high ponytails, nails are too sharp when washing hair, it is easy to irritate the scalp, cause the scalp to become fragile, and 脂溢性脫髮.

It is recommended that when protecting the scalp, it is recommended that you try to protect the barrier tissue of the scalp. When choosing a comb, you can use a wooden comb to reduce the irritation to the scalp; the hair should be in a distributed state to avoid binding the scalp and causing unnecessary hair loss. ; Use non-irritating hair care products.

Malnutrition is an important cause of hair loss

Some people don’t understand why malnutrition is also a factor in hair loss. In fact, the reason is very simple, because hair is also a sign of physical health. For example, dry hair, irritability, and yellowing may indicate insufficient nutrition in the body.

Instead, a balanced diet and reasonable supplementation of nutrients, such as high-quality protein, dietary fiber, vitamin B, and a variety of minerals needed by hair, can promote the production of melanin particles in the hair follicle to a certain extent, which is beneficial to the black hair. form.

Is only 20 platelets life-threat...


The normal platelet count is between (125-350)×109/L. Is it serious when the blood routine report reduces the single platelet to only 20? Will it be life-threatening...

The consequences of platelets as low as 20

The main function of platelets is to stop bleeding and normal platelet count blood. When the platelet value is lower than 100, it means thrombocytopenia, and when the platelet value is lower than 50, there is a risk of bleeding. Therefore, when the platelet value is as low as 20, it means that platelets are severely reduced, and severe bleeding symptoms such as skin and mucosal bleeding, hematuria, and hemoptysis will occur. patients cannot work and live normally, and severe cases may even cause cerebral hemorrhage and endanger their lives.

How long can platelets be as low as 20?

There are many reasons for a low platelet count, and the number of platelets depends on the underlying disease that caused the low platelet count.

Simple thrombocytopenia: platelets as low as 20, increase the risk of bleeding. Long-term survival can be achieved through treatment.

It is also called primary thrombocytopenic purpura or idiopathic thrombocytopenic purpura. As long as the patient is given timely and effective treatment and the patient's condition is effectively controlled, he can work and live like normal people and survive for a long time.

Aplastic anemia: The platelets caused by aplastic anemia can be reduced, and timely and effective treatment is very important. The survival period of patients with aplastic anemia will continue to increase. If our treatment effect is not good, the patient's survival period will be shortened. .

â‘£Acute leukemia or other malignant tumors: This type of disease has a rapid onset and obvious symptoms. The average survival period is only about three months. If the treatment effect is not good, the patient's survival period is relatively short.

Hyperactivity of the spleen function: The platelets caused by the hyperactivity of the splenic system can be reduced. After the spleenectomy is performed, the platelet passing value will be restored after the body is healthy and recovered.

Whether the number of platelets is as low as 20 can not be cured is mainly due to the primary disease that causes thrombocytopenia. Therefore, patients with thrombocytopenia should go to the hematology department of a regular hospital for treatment in time. Definitely diagnose the development of the primary disease that causes thrombocytopenia and its important reasons, and carry out an active and effective treatment to improve the platelets rationally and effectively, and the patient can achieve long-term survival.

How to treat platelets as low as 20?

Low platelet count is guided by Chinese medicine and supported by Western medicine. Special preparations are combined with Chinese medicine decoctions, and a diagnosis and treatment plan is formulated according to the patient's course of illness.

For patients with severe thrombocytopenia such as thrombocytopenia to 20 and severe bleeding, emergency treatment measures such as hormone, immunoglobulin infusion, and platelet suspension infusion are taken, and then traditional Chinese medicine is the main treatment.

The test strategy for electric v...


1. Application conditions

Owners of electric vehicles with over-standard licenses must meet the relevant conditions and carry relevant materials before they can enter the test.

The application requirements are: 18 years old but less than 70 years old, in line with the physical conditions and requirements motorcycle cub 125cc by the law;

For the initial application, you need to submit the medical examination form, the applicant's identity certificate, 6 one-inch white photos and other materials.

2. How to test?

Car owners need to train at the designated driving school; after the training, go to the local car management office to make an appointment for an exam. There are three subjects, and the examination fee is 335 yuan, of which training fee is 100 yuan (collected by the driving school), the examination fee is 225 yuan, and the cost of production is 10 yuan. Citizens can apply for a three-month test at a driving school with training qualifications. If they pass the exam, they can get a moped driver's license (F certificate).

In addition, holders of D, E, F certificates do not need to take an exam. Drivers who already hold a three-wheeled motorcycle driver's license (d certificate), an ordinary two-wheeled motorcycle driver's license (e license), and a moped driver's license (f license) do not need to apply for the test, but they can drive electric bicycles beyond the standard. However, a driver with a moped driver's license (F license) cannot drive ordinary two-wheeled motorcycles and three-wheeled motorcycles.

Citizens who hold D, E, and F certificates but have not had an annual review for more than three years and have their driver's license cancelled need to take a test. If the holder of the certificate is not sure whether the certificate is valid, he can go to the vehicle management office for inquiries. If the system displays "Normal", there is no need to take the exam again; if it displays "Logout", you can resume, and you only need to take the subject one exam; if it displays "Cancel", you will take the exam again.

Three, what to test?

Subject 1: Road safety laws and regulations and related knowledge. paper test paper, 50 questions, 45 minutes, full score of 100 points, 90 points qualified.

Subject 2: Field Skills Test (pile test, ramp fixed-point parking and start, passing a unilateral bridge), with a full score of 100, and a score of 80 is considered a pass.

How to get a scholarship in coll...


Many people are very concerned about university scholarshipss in college. Today, I will also talk to you about scholarships in college!

Generally, people who have just entered college are more confused about their future school life and have no set goals. If you really have no goals, then take the scholarship as the overall goal! It is likely that the scholarship will become the first bucket of gold in your life path!

First of all, to get a scholarship there is a most most basic criteria, that is, must not fail the subject. If you fail, then you have to get a scholarship in that one academic year is only a matter of thought. The most important thing is to make sure that you don't fail a class, so I can talk to you about how you can get a scholarship.

Scholarships are divided into national and university level. The national level has national scholarship and national classic inspirational scholarship, the amount of national scholarship is 8000 yuan, the amount of national classic inspirational scholarship is 5000 yuan. At the school level, it depends on the amount set by each institution, like our school, the first-class scholarship is 2000 yuan, the second-class scholarship is 1000 yuan, and the third-class scholarship is 600 yuan, the amount is still able to count. So how can we get this kind of scholarship?

Today, we will talk about school-level scholarships with the guys!

The first thing you should do is to get to know the criteria for school-level scholarships. The standard of each institution will be established in the student handbook, but most of them will be similar, that is, based on the comprehensive assessment of each student to identify. The most important thing is that you will be able to get a scholarship if you rank in the top 30% of your class in the comprehensive assessment.

If the scholarship is based on the comprehensive assessment, then how can we improve our own comprehensive assessment scores?

There are two main levels of achievement here.

First, hard work and learning. Do not fall behind in the professional knowledge of the textbook, and strive to get a higher grade in each subject. In college, it is easier to get higher grades than in a normal high school. Because in college, you do not need to brush a lot of questions, if you lecture listen attentively, after class practice to write a practice problem in the book. Exam before and then prepare for the exam preparation, write a previous year's exam questions, then your final results are not easy exams can pass very poorly, because you will find the final exam topics and books are very similar, and even can test the real questions oh!

Second, more participation in some of the more highly recognized competitions, such as subject competitions, independent entrepreneurship innovation competition, Challenge Cup these. This kind of high recognition competition in your final identification scholarship is also able to add many points. And, if you have been in this kind of competition to get better results, is also able to have reward money Oh! Therefore, it is necessary to learn more professional skills when you have nothing to do during practice hours after school!

So to get a school-level scholarship, either you have a good technical major, or you have participated in more competitions, or you are better at both levels. See if this has the feeling that it is actually easier to get a scholarship or not!

Wearable work pressure sensitive...


In recent years, the use of wearable sensor devices has become a part of everyone's daily life. For example, devices such as smart bracelets can be used to monitor the body's movement and fitness effects, such as heart rate, sleep quality and fitness exercises.

But technological developments have opened up a lot of possibilities for monitoring the physical and mental health of patients. Sensors can now be applied to wearable or portable devices to accurately measure key health indicators in the blood night, such as metabolic substances, O2 or the level of healing drugs. This gives patients a simple way to perform continuous, less invasive, instant tests at home for diagnostic or therapeutic purposes. Having that kind of system software would greatly jeopardize patient and provider requirements, thereby reducing the need for frequent hospital visits and incentivizing compliance with medical treatment.

One such sensing device is designed to respond to small shifts in body pressure, allowing for more sensitive and continuous detection of physical effects such as pulse rate, blood pressure values, respiratory rate, and even small shifts in vocal cord polyp vibration in a high aspect ratio. The pressure-sensitive device is made into an adhesive tape and subsequently added to the skin at a single pulse point on the wrist or head and neck. The precise measurement of this physics can be as simple as applying the sensor to the skin and then submitting the collected data information for remote connection by the physician.

The pressure-sensitive device should be made of a material that has excellent ductility and physical properties. The material should also be compatible with the skin surface and conform very well to the skin surface. Over the past decade, a variety of natural and composite materials have been tested, but their physical properties have not been found to be the best.

H50

The different types of gel-like raw materials, called hydrogels, give exceptional process performance for pressure-sensitive devices, but present a number of challenges: water evaporation, lack of structure and lack of scale, and economic development of efficient manufacturing methods.

A collaborative team consisting of an elite team from Terasaki's Biomedical Engineering Innovation Laboratory has already devised solutions to the challenges that occur when building wearable pressure-sensitive sensors. The team selected a hydrogel based on pectin because of its excellent malleability, skin compatibility and low cost. It also gives a way to adjust its malleability, constructional properties and working pressure sensitivity by changing its production method and concentration values of its components. These hydrogels have the added benefit of being light-transmissive when dry and solid, making them attractive as wearable microbial sensors.

The elite team conducted general experiments to raise the bar on what was needed to make a hydrogel with the desired properties. They then assembled it together with fully transparent electrical device components into a completely transparent strip, including the hydrogel layer embedded in it.

"The development we have obtained at the hydrogel sensor level allows everyone to succeed in getting rid of the challenges generated by previous diligence," said Dr. Seiming Zhang, a doctoral student who is part of the elite team of scientific research at Terasaki Research Laboratory."" This will enhance the application of pressure-sensitive devices in many likely diagnostic and therapeutic applications, which include not only the continuous detection of blood pressure values, pulse rate and heartbeat counts, but also the precise measurement of vocal fold polyp vibrations and their early detection of rattling and swallowing difficulties."

To improve the overall durability of the final product and to avoid water evaporation from the hydrogel layer, the elite team enhanced other processes throughout the manufacturing process: organic chemical solutions for the components to improve compressive strength, and strategic dry fixing of the hydrogel layer to best integrate with the surrounding electrical components.

wearable medical products

In another distinctive process in the manufacturing process, a surface of the hydrogel layer was molded into a grid pattern consisting of pyramidal protrusions, which facilitated the working pressure sensitivity of the finished sensor. According to the experiments the size and spacing of such projections to obtain the best results were able to enhance this effect.

The working group carried out general tests on the sensor and the results showed that the whole manufacturing process successfully solved the difficulties of water evaporation and lack of structure in a solid way. In addition, the sensor can accurately measure the working pressure shift with higher sensitivity and consistency, and can be manufactured with higher cost effectiveness and scalability compared to previously observed sensors.

Sad to say, you can’t listen to it as early while you can by having an fetal doppler. Which has a stethoscope, a baby’s heartbeat is commonly detectable in between the 18th and twentieth 7 days.

Stethoscopes are developed to amplify small sounds. It's a upper body piece that connects to some tube. The chest piece captures the audio, and then the audio travels up the tube to your earpiece.

The place do you obtain a stethoscope?

Stethoscopes are extensively obtainable, and that means you never have to function inside the clinical field to acquire one particular. They’re sold at healthcare supply retailers, drug retailers, and on the web.

Nonetheless, have in mind that not all stethoscopes are produced equal. When buying for one, study assessments and solution descriptions to be sure you receive a product that actually works for you.

You'd like a stethoscope with great acoustic and audibility quality, also as a single that’s lightweight to ensure it’s cozy all-around your neck. The scale with the tube also matters. Usually, the larger the tube, the more quickly the seem can vacation to the earpiece.

2. Endocrine disorder.

Many women will have vaginal dryness at the age of thirty or ten, which is very annoying. In fact, it may be caused by endocrine disorder. It is important to know that human functions will keep declining after the age of 35. Women experience vaginal dryness due to insufficient vaginal secretion or estrogen secretion, and their ovarian function and endocrine function will also decrease.

Third, excessive cleaning.

Why does it cause vaginal dryness? In fact, it may be that you are over-cleaning. Many women listen to TV commercials for many reasons and are too gullible, so they frequently use various vaginal washes for cleaning and even irrigation. However, when you over-clean, the vaginal flora is destroyed and the acid-base imbalance leads to vaginal infection and vaginal dryness.

Four months after childbirth

Many women suffer from vaginal dryness after childbirth, which is caused by physical fatigue, their lack of desire to live their lives, and breastfeeding. The increased secretion of prolactin affects the secretion of estrogen, which leads to a decrease in estrogen levels and leads to vaginal dryness.

These are some of the causes of vaginal dryness, do you belong to this condition? It is not difficult to improve vaginal dryness. If it is not due to disease, pay more attention to the hygiene of your private parts in daily life, use warm water to wash and do not use various gynecological lotions. You can also take some endocrine-regulating foods. If the vaginal dryness is caused by disease, you should actively treat it!

Password identification access control system

By verifying that the password entered is correct to identify access rights. This type of product is divided into two categories, one is the general type, a type of chaotic keypad type (keypad number is not fixed, not regularly changing automatically). The advantages of password 門禁 recognition are ease of operation, no need to carry cards, and low cost. The disadvantage is that security is poor, easy to leak, only unidirectional control, no open records, the key is easy to damage, failure.

Swipe card identification access control system

According to the type of card, can be divided into contact card access control system (magnetic stripe cards and barcode cards) and non-contact card access control system (also known as induction cards and radio frequency cards). Contact products used in the card is easy to wear, information is easy to copy, susceptible to external magnetic field interference, the use of scenarios less, generally only in the bank card (magnetic stripe card) related to the occasion to use. Contactless cards have the advantages of ease of use, durability, fast reading speed, and high security.

Biometric Access Control System

Access is identified by examining staff and biometric features. There are fingerprint type, palm type, iris type, facial recognition type, finger vein type, etc.. Its advantages are not lost, will not be stolen, no memory password burden, security provides convenience. However, the stability and accuracy of our country's biological risk identification is still developing to further enhance the product market price is also higher than the previous two types, applicable to different scenarios design also has its own certain limitations.

After more than 20 years of development, the access control system has gradually become a complete access control management system. With the continuous development of the security industry, the traditional password identification and card identification has been difficult to meet market demand. The development and rise of the Internet of things, cloud computing and smart mobile devices, prompting companies to develop new products and technologies to obtain greater market space and product profitability.

The purpose and performance of reflow soldering device, comprehend


The reflow soldering equipment is usually a soldering tools used for full-surface assembly. From the reflow soldering device, the conveyor belt transports the solution spherical and spherical for reflow soldering. The reflow soldering machine consists of a heater element, a transmission element, and also a temperature handle part. So...

smt reflow oven

one. The purpose of reflow soldering equipment

The purpose of reflow soldering is always to send the mounted circuit board from the SMT elements to the SMT reflow soldering chamber. Soon after high temperature, the solder paste used to solder the SMD components is melted because of the procedure of substantial temperature scorching air to type a reflow temperature change, in order that the SMD components and the pads within the circuit board are put together and after that cooled jointly.

Next, the perform from the reflow soldering equipment

1. According to the development of engineering, the reflow soldering machine is split into: fuel stage reflow soldering, infrared reflow soldering, much infrared reflow soldering, infrared heating air reflow soldering, whole hot air reflow soldering, and water-cooled reflow soldering. It is actually a welding technologies developed using the emergence of miniaturized electronic solutions, and it is primarily employed for welding numerous surface mount parts. The solder for this soldering technique is solder paste. You will find a heating circuit within the reflow soldering device, which heats air or nitrogen to the substantial more than enough temperature and blows it for the circuit board where by the component has actually been attached, to make sure that the molten material on equally sides on the element is melted and bonded along with the motherboard.

two. The benefit of reflow soldering device is the temperature is simple to manage, oxidation could be averted through the soldering system, along with the manufacturing value is less complicated to control. Use a proper volume and proper type of solder paste over the pads of your circuit board beforehand, after which paste the SMT components into the corresponding positions; the solder paste includes a selected viscosity to fix the elements; then let the parts be mounted The circuit board enters the reflow soldering equipment.

three. The main utilization of reflow soldering is within the SMT approach. Inside the SMT approach, the primary result of reflow soldering will be to set the PCB board along with the factors inside the track from the reflow soldering device, and then warmth up, heat up, solder, cool, etcetera. During the hyperlink, the solder paste is changed from a paste to some liquid at a significant temperature, and after that cooled into a stable, and afterwards the impact of soldering the chip digital elements plus the PCB board is completed. The main a part of the reflow soldering equipment would be to use an external heat supply to warmth, to ensure that the solder melts and flows and infiltrates once again to finish the soldering method of your circuit board.

How to calculate house mortgage interest


Nowadays, more and more people are buying houses, and banks’ loan companies are becoming more and more popular. However, many of them are not very clear about the interest calculation ability of Bank of China’s bad loans. How should the mortgage interest be calculated? Let me give you a specific calculation.

供樓利息

1. Mortgage down payment: When buying a house for the first time, banks generally require a down payment of 30% of the house price; if buying a second house, the down payment ratio is higher. The specific standard should refer to the prevailing standards in this city.

2. Bank loan interest rate: interest rate item annual interest rate (%), if the loan needs to estimate some daily interest, you can use annual interest rate/365 to convert to daily interest rate.

86 people within 6 months (including 6 months);

6 months to 1 year (including 1 year) loan 5.31;

1-3 years (including 3 years) loan 5.40;

3-5 years (including 5 years) loan 5.76;

Loans over five years 5.94

There are two ways to calculate mortgage interest:

1. Equal principal repayment method: The loan amount is divided into n equal periods according to the number of repayment periods, and the loan interest rate is multiplied by the outstanding principal in each period until the current interest is repaid;

2. Equivalent principal and interest repayment method: The principal and interest are annualized during the loan period, and the sum of the principal and interest returned in each period is equal. The first instalment interest is the amount of the principal occupied by the loan interest rate. The equal annuity paid in each period minus the first instalment is the principal repaid in the first instalment; the second instalment is calculated to repay the principal in the first The money is subtracted from the total loan principal to obtain the principal amount of the second period, and then multiplied by the loan interest rate to obtain the interest payable in the second period, and so on to subsequent periods.

The level of the loan interest rate can directly affect the profit distribution ratio between the bank and the development of the borrowing enterprise, and therefore affect the economic and social interests of both parties. Loan market interest rates vary with the types and maturities of online loan products, and are closely related to the scarcity of loan funds.
