美国背景提升

近年来，美国背景提升这一块的背景提升内容一直是准留学生们的热门选择。美国夏校、美国当地的科研项目、各种竞赛一直都是暑期的热门项目。每到暑期很多准留学生都会选择前往美国夏校进行短期的学习，提前感受美国高等院校课堂的学术氛围；也有不少准留学生选择跟教授做一个含金量高的项目或者前往参加国际性的赛事，这些都是美国背景提升的范畴，不仅能够让自己的假期变得更加丰富多彩，也能提升自己的学习能力，还能为自己的大学申请起到锦上添花的作用。

疫情下，美国背景提升该何去何从

近日已经是美国夏校的申请高峰了，然而无情的新冠病毒席卷世界各地，美国高校也纷纷停课或者转为线上课程了。这场无法估量的疫情将准留学生们的暑期安排计划彻底打乱，例如夏校申请之路变得异常曲折，一方面无法预测疫情接下来会如何发展，暑假期间是否足够安全前往美国参加夏校项目，另一方面也担心国内所就读的高中会在暑期做出补课安排。太多的不确定因素令众多学生产生了各种各样的担忧，也在一定程度上耽误了准留学生背景提升规划。

求真教育再次建议各位学子，不要因为受新冠疫情影响而停滞自己的背景提升计划。美国高校的招生并不会因为疫情而降低要求，我们不断地提高自己的综合竞争力才是良策。线下的活动受影响的话，不妨考虑线上的美国背景提升项目。美国众多高校都开设有在线夏校课程，学生们可以在家通过互联网来进行学习、与教授交流，与同学合作分享。

线上模式可以让学生打破时间、空间的限制来进行学习，继而提高自己的背景软实力，在接下来的美本申请中体现自己的超强背景实力，赢得招生官的青睐，获得梦校的橄榄枝。

Where are we talking from today?

New Orleans, Louisiana.

Where did you get your artist's name from?

So, our artist's name was partially inspired by the experience of going through the songwriting mentorship process with our mentor, Loren Israel. We feel like the whole experience helped us delve deeper and be more honest and vulnerable in our songs and writing. Deeper into the “Blue” as it were. Blue is also a power color for both of us, so with some creative thinking, we came up with N2BLÜ.

Music-wise what are you working on right now?

We have actually finished our first album, titled “Phoenix Heart," which will be releasing this summer and we have already started our next album.

Are you currently promoting a single or album?

We are currently promoting our latest single, Kiss Me Like the Devil, which is available on every online music platform along with the lyric video on our YouTube channel. We will actually be releasing our next single, “Again”, and lyric video on April 21, 2020.

Who or what were the most significant influences on your musical life and career?

For me (Jonathan), my biggest influences growing up were Better Than Ezra, Duncan Sheik, and Savage Garden. For Kosta, his biggest influence growing up was DC Talk.

As a musician, what is your definition of success?

I’d say our definition of success is being able to do what we love (making music), being able to share it with the world, and helping other people through our music.

Mud pump parts are used on drilling rigs for the circulation of mud. These reciprocating pumps are suited for the process of drilling oil wells. We, at Saigao offer a wide selection of remanufactured, used and new drilling equipment for domestic and international drilling companies. We understand the needs of our clients and hence are better equipped to offer you the best drilling mud pump parts.

A Few Facts of Mud Pump Parts

There are three basic different types of drilling mud pumps each with their own unique set of components and parts.

Triplex: This mud pump is used for drilling applications needing high pump pressure. This model works by decreasing the working fluid volume being discharged to generate pressure for producing the flow. There are three pistons in the triplex pump, with the middle piston generating more pressure to the crankshaft. High piston load can lead to excessive pressure and crankshaft failure, if the components are not properly sourced.

Quintuplex: These pumps are perfect for pumping fluid at the time of drilling operations. It works as a continuous duty return piston. This is used in terms of its external bearings to provide crankshaft support to ensure proper functioning of the sheaves.

Duplex: These mud pumps ensure that the mud circulation reaches the well’s bottom from the mud cleaning system. Duplex pumps have binocular floating seals as well as safety valves.

Saigao offers high quality OEM mud pump spares, consumables, expendables and spare parts. Our mud pump parts are made with the highest standards of quality, offering competitive pricing and exceptional durability.

Features of china mud pump parts

These pumps can be differentiated into single and double acting pumps as per completion time of the suction and drainage action in a cycle of the reciprocal motion of the piston. Mud pumps are available in a variety of sizes, in addition to the types, viz., triplex, duplex or quintuplex. The latest developments are hex pumps with 6 vertical pistons and quintuplex with 5 horizontal plungers.

Parts of a mud pump crankshaft

The fluid end provides valves, liners and pistons for the pumping process. These are high wear items requiring frequent replacement of parts. Severe vibrations caused by the pumping process necessitates a suction and discharge pulsation dampening component. Power end of the mud pump transitions the power of the drive shaft to the piston’s reciprocating motion. Parts of the mud pump include the plunger, piston, modules, housing, cover plus packing, piston rod, suction and discharge valves with their seats, stuffing box, pulsation dampener and glands.

Smooth operations will be possible when the right quality mud pump parts are sourced. Saigao offer a wide range of mud pump parts that will partner the operations of rugged mud pumps for extended periods.

ERW pipe(electric welded pipe) means electric resistance welded pipe, and it is a resistance welding by 10-500 kHz of high-frequency current. The raw material of electric resistance welded steel pipe is hot rolled steel coil which is made of steel billet, and the usual erw pipe grade is Q195, Q215, Q235, Q355 in China steel grade, which are same material with S195, S235, S355 in Europe, and SS400 in Japan. Steel coil firstly will be cut into strip, the strip width is according to the perimeter of pipe, and then shaped by mold, welding, cutting, straightening, inspecting, end smoothing, packing, and final storage or dispatch. The pipes are used widely in construction and infrastructure, such as scaffolding, water and gas delivery, fire control system, oil and heat delivery, and other low-pressure liquid delivery. Generally speaking, the length of pipes produced by the erw steel pipe suppliers are 6m, which can be determined according to the requirements of the buyer.

Safely protect your valuable fruit. These plant support netting will effectively shield your ripening fruit from preying birds and insects. Date palm bags are also great for placing over entire plant (depending on size), placing over clusters of fruit, or individual piece of fruit. These bags are typically applied one time before fruits maturity, and then remove during harvest. These bags can assist in controlled pollination. Protection Bags offer exclusion in a simple organic strategy that relies on preventing access to pest, their derived viruses and disease. These bags will simply catch ripening dates and other fruit from falling onto the ground now contributed to a higher yield.

Unique opening and bottom design help farmers achieve higher yields.

The size of space

The size of the space is the size of the living room, movie room, etc. where you use the   mini home projector. If your living room area is more than 20 square meters, you can consider buying a projector; if not enough, it is not recommended.

Price

The price gap of projectors is large, generally from a few thousand yuan to about 50,000, or even higher. The prices of foreign brands are higher than domestic prices. Domestic projection prices are lower. The reason is not explained in detail. For most consumers, products below 30,000 yuan can meet household needs.

Brightness

Brightness is one of the most important indicators for purchasing a projector.

Noise

Those who have never used a projector do not know that the projector will make noise when used. The noise of some projectors can severely affect viewing and is unbearable. When purchasing a projector, considering low noise should be an important part of the purchase. At present, many manufacturers have launched low-noise projectors, and the price is not expensive. Generally speaking, products with a noise level below 40dB are acceptable, but when buying, you should listen and compare yourself in a quieter environment to see if it will interfere with yourself.

Choose DLP or LCD

Whether it is LCD or DLP is actually not so important. What we need to see is the effect of the projector. And the effect of a projector is inseparable from many things such as lenses, light bulbs, and circuits. In principle, LCD projectors are the most common and their prices are relatively low. The biggest advantage of LCD projectors is that the colors are great. The three primary colors of red, green and blue are completed by three separate LCD panels. The brightness and contrast of each color can be controlled individually. And three colors of light can reach the screen almost simultaneously, so various colors can be reproduced realistically. Although the color reproduction of DLP projectors is slightly worse, the three-color light of a single-chip DLP projector is reflected by the same micromirror to the same pixel, and there is no convergence problem, so the black area is truly black, and the edge of the pixel will not appear Some burrs and shadows in the LCD. Therefore, when showing some thin lines, DLP projectors are clearer and sharper than LCD projectors, black and white are more pure, and gray levels are richer. Of course, the biggest advantage of a single-chip DLP projector is its small size and light weight. Many products even have only 1-2 kg. Generally speaking, DLP projectors are slightly more expensive. Seeing is believing. Whether it is LCD or DLP, it is recommended to compare carefully at the time of purchase.

Trapezoidal correction

In the use of the projector, the position of the projector must be at right angles to the projection screen as far as possible to ensure the projection effect. If the verticality of the two cannot be guaranteed, the picture will be trapezoidal. If it is not on the ceiling, but on the table, it is difficult for us to guarantee "vertical". In this case, we need to use the "keystone correction function" to correct the keystone to ensure that the picture has a standard rectangle. Keystone correction usually has two methods: optical keystone correction and digital keystone correction. Optical keystone correction refers to adjusting the keystone by adjusting the physical position of the lens; another type of digital keystone correction is software to achieve keystone correction. At present, almost all projector manufacturers have adopted digital keystone correction technology, and most of the projectors using digital keystone correction support vertical keystone correction function, that is, the projector can adjust its height in the vertical direction. The resulting trapezoidal is trapezoidally corrected in the vertical direction by the projector. The picture can be made rectangular, which is convenient for users.

1. Try to be generous
   The first time you go to a man's house, don't be too deliberate, be easy-going and show your natural side. Of course, as a girl, help his mother do housework together. If his mother is cooking, you can go to the kitchen to help do it together. Even if you are not very good at, you can choose dishes and wash vegetables. The simple housework is good, so that the man's family feel you are very sensible and diligent, why not? Preservation is a girl's characteristic, but when it's natural and generous, can't twist and pinch, too shy to let go may not be a good phenomenon.
   II. Be punctual
   It's better to go in the morning of the day. Never go in the evening. It's the basic etiquette to show respect and to imply that you are a hard worker.
2. Gifts are indispensable
   The first time you go to a man's house, you can't leave empty-handed. You always want to buy some gifts, but you can't decide what to buy. This gift is not too much, but it must be bought. It is not necessarily practical but to buy good-looking and handy ones (because you are still an outsider after all in their psychology, so you must be decent).you can give his mother dark red quinceanera dresses.
   Pay attention to courtesy
   The people of the previous generation are more serious about this. Before going to the man's house for the first time, you can ask your boyfriend if they have any special etiquette. If there is no special, keep in contact with the elders. Modest attitude can be described as the biggest etiquette. When entering the man's door, the woman's mouth must be sweet, such as smiling and asking uncle and aunt, this is the first impression of the first time (very critical).
   V. Dress generously and appropriately
   Don't be stupid too exposed. if you are unconventional, who dares to give their son to you? They expect you to take care of their baby son's diet and living after marriage. It is necessary to be generous and decent and virtuous. It's important to remember that beauty is only shown in a safe range, otherwise it will arouse the jealousy of future mothers-in-law, and you will suffer in the future,sucn as light purple sweet 15 dresses
   VI. Be clever and sincere in speaking
   To chat with future parents-in-law, talk about the physical condition of them, the usual habits, but also ask the future husband's previous achievements, children's interesting things. If the future parents-in-law asks about your family situation, you should also answer frankly and give a good answer - not to tell you to brag, but to show your concern and love for your family, and those unhappy and unhappy things should be put aside for the time being.

Your boss is finally convinced by you to replace the ergonomic chair for computer users. After working in the new chair for a day, you feel much better than before and can focus on work for longer time. After working for a while, your back pain also starts to improve. Your colleagues can also notice that you are more engaged and productive than in the past few months.

The ergonomic chair for computer users is designed to help you sit comfortably for long periods of time at work. They are more adjustable than standard office chairs and allow you to adjust to your body or seating preferences.

We provide ergonomic office chairs online sale,those chiars increase your productivity and increase your job satisfaction, and they also reduce the risk of musculoskeletal injuries. Here are five specific reasons why an ergonomic chair can relieve your waist and back pain.

1.Support proper posture when sitting on ergonomic chairs

The most important reason that ergonomic chair for computer users can improve waist and back pain is that they are designed to support your natural posture and reduce stress on your body. The seat back usually extends from the shoulder to the seat position. The lower back forms a slightly curved forward structure to match the natural curve of the lumbar spine. This is often called lumbar support because it helps protect the lumbar spine.

The adjustable armrest of the ergonomic chair supports your elbows and forearms as your arms naturally hang next to your body. This allows you to use your keyboard and mouse without causing fatigue in your shoulder and arm muscles. Adjusting the seat height allows you to lay your feet flat on the floor with your hips and knees bent to about 90 degrees.

Some ergonomic chairs have backs that can be moved forward or backward to reduce the depth of the seat and prevent the front edge from cutting into the back of the knee.

2. Proper hip and pelvis alignment when sitting on ergonomic chairs

A common cause of back pain caused by incorrect sitting is improper alignment of the hips and pelvis. The top of the pelvis should be level to prevent tilting forward or backward. When the computer chair you sit in a correct posture, the pelvis bone structure known as a bone to be flush with each other, are located in the front and rear portions of the pelvic bone. When these bony structures are horizontal, your waist should be slightly arched with the raised parts facing forward.

If you sway from side to side, you should feel the pressure on the bone structure called the ischial tuberosity. These are also called ischias because they should be the weight-bearing part of the pelvis when sitting. If you've ever sat on a hard bench, you will most likely feel your ischial tuberosity press into a hard surface.

3. Prevent shaking and lean forward head posture when sitting on ergonomic chairs

When you sit down, the lumbar spine bends and your shoulders roll forward to create a slack posture. In this position, your scapula is away from the thoracic spine and your head is moved forward or extended. When you look up at your computer monitor, your neck moves to an extended position. If you continue working in this position, this can cause muscle strain, pain, and headaches.

Internal and external factors can cause slackness. Internal factors include limited hip flexion range, tight hamstrings, obesity, and weak torso (core) muscles that fail to keep the spine upright against gravity. External factors are factors outside the body, such as limitations of chair design. These include seat lengths that are too long or too short, seat backs that are too vertical, and armrests that are too low.

Ergonomic chair for computer users may not change your internal constraints, but they are specifically designed to correct external factors. Adjustable seat depth and contours of the seat back support the waist, prevent lazy body states, and promote you to sit in place. Some chairs also allow you to adjust the angle or tilt of the seat back. Use a properly adjusted ergonomic chair to prevent looseness and forward head posture.

4. Reduce repeated bending of the body on ergonomic chairs for computer users

A side effect of sitting poorly on a standard chair is that it requires repetitive bending of the body to ease it. This is likely to happen several times a day and can cause pain in your waist. Sitting on an ergonomic chair with good back support will allow you to sit more straight.
