美本转学申请

学生：F同学

GPA：3.8+

TOEFL：98

申请专业：数学

录取学校：约翰霍普金斯大学、密歇根大学安娜堡分校、纽约大学等

求真案例

F同学刚在美国入读大一，他的爸爸就找到了求真教育咨询美本转学申请，因为听说孩子入读的排名60名左右的大学是一所party school，担心他荒废了学业。老师十分理解家长的担忧，学校大环境对孩子的影响确实非常大。在和F同学深入交流之后，老师发现他是个遇强则强的孩子，虽然在美本申请时条件平平，但是潜力很大，如果能从玩着学转变到认真学，这其中的飞越可能会让我们刮目相看。于是建议他们开始着手准备大三转学。

求真助力

大一期末考试结束后，F同学给申请老师的反馈是学校的课程难度一般，想拿A也不是太难。因此老师对他提出了更高的要求，课不能选水课，GPA不能低于3.8。基本的要求和选课谈妥后，老师们就开始着手另外一项重大工程：背景提升。在挖掘了F同学的家庭背景和实践经历后，老师给他安排了两个课外活动，一是社科类的，体现他对弱势群体的关注，通过调查研究并付诸实践，体现了他的思辨和行动能力；二是科研类的，跟着学校教授在国家重点实验室做了两个月研究，体现他的学习能力和科研素养。

有了一系列的铺垫，文书写作的过程可谓非常顺利。求真教育对于文书创作有着自己的原则，不深入挖掘不写文书，不做背景提升不写文书，不了解孩子不写文书。当做到了这三点后，文书就水到渠成了。文书老师把孩子对专业的理解和丰富的实践经历通通融入了主文书当中，呈现了F同学真实的想法和绝对的实力。

求真寄语

不出老师意料，在三月份时，F同学就收到了密歇根大学录取，但是大家心里都在期待着收到更好的消息。终于功夫不负有心人，半个多月后，我们收到了约翰霍普金斯大学抛来的橄榄枝。在众多申请的学校中，这算是F同学和他的父亲最最心仪的结果了。求真教育的老师们也由衷地为他们感到高兴！求真教育有多年美本转学申请的经验，越早进入服务能为申请收获更好的结果。文章来源：https://indeededu.com

Operation method of the staples used in surgery: An intestinal anastomosis is used to illustrate the use of the stapler. The anastomosis is sutured in the proximal intestine, placed in the staple holder and tightened. The stapler is inserted from the distal end, the central piercer of the stapler is threaded out and articulated with the central rod of the proximal stapler against the staple holder, and rotated close to the distal and proximal bowel walls. Adjust the distance between the staple holder and the base according to the thickness of the intestinal wall, generally by turning the hand tighter (with a tightness indicator pin on the handle).

Squeeze the closing anastomosis wrench to tighten the anastomosis, and the sound of the sound indicates that the cutting anastomosis is complete. Do not withdraw the anastomosis and check to see if the anastomosis is satisfactory and if other tissues, such as the mesentery, are embedded. After being dealt with accordingly, the anastomosis was unscrewed and gently pulled from the distal end to check for the integrity of the distal and proximal bowel resection rings.

Precautions for use of the stapler

(1) Before the operation, check whether the ruler and 0 scales are aligned, whether the assembly is correct, and whether the push-piece and tantalum nail are missing. A plastic washer should be installed in the resistor.

(2) The broken end of the intestine to be anastomosed should be fully free and stripped at least 2cm.

(3) The distance between the stitches of the purse suture should not exceed 0.5cm, and the margin should be 2~3mm so that too much tissue is easy to embed in the anastomosis and hinder the anastomosis. Be careful not to omit the mucosa.

(4) Adjust the spacing according to the thickness of the intestinal wall, with 1 to 2 cm being appropriate.

(5) Check the stomach, esophagus, and other adjacent tissues before hitting to prevent clamping into the anastomosis.

(6) The cut should be made quickly, and pressure should be applied at the end to make the staple into a "B" shape.

(7) Exit the surgical stapler gently and check whether the incised tissue is a complete ring.

Victor Medical Instruments Co., Ltd is a professional firm of auto surgical staplers and minimally invasive surgery equipment, we provide open surgical instruments.

DMF-Z Right Angle Electromagnetic Pulse Valve Product introduction:

The electromagnetic pulse valve is imported from abroad (also known as the diaphragm valve) is the compressed air "switch" of the pulse bag filter dust cleaning system is controlled by the output signal of the pulse injection controller, and the filter bag is cleaned by the row (chamber). Ash, so that the dust collector's resistance is maintained within the set range, in order to ensure that the dust collector processing capacity and vacuum efficiency.

DMF-Z Right Angle Electromagnetic Pulse Valve Features:

The DMF-Z electromagnetic pulse valve is a right-angle valve. The angle between the inlet and outlet is 90°. It is suitable for the mounting connection between the helium cylinder and the dust blower tube. The gas flow is unobstructed, and it can provide the turbulent gas flow that meets the requirements.

DMF-Z Right Angle Electromagnetic Pulse Valve working principle:

The diaphragm divides the electromagnetic pulse valve into two air chambers, front and rear. When the compressed air is turned on, the compressed air enters the rear air chamber through the throttle hole. At this time, the pressure of the air chamber presses the diaphragm against the output of the valve. The pulse valve is in the "closed" state.

The electric signal of the pulse injection controller causes the electromagnetic pulse valve armature to move, the air chamber vent hole opens after the valve, the rear chamber quickly loses pressure, the diaphragm moves back, the compressed air is blown through the valve outlet, and the electromagnetic pulse valve is "opened" status.

Pulse injection control instrument electrical signal disappeared, electromagnetic pulse valve armature reset, after the air chamber vent hole closed, the rear chamber pressure increased so that the diaphragm close to the valve output, the electromagnetic pulse valve is in the "closed" state.

If you are looking for diaphragm valve manufacturers, Senotay can be a competitable one among those diaphragm valve suppliers. Contact us to get more information about our products!

Design principles for the runner system:

1. For the single plastic part and multiple cavities, the balanced runner (except special) should be used, that is, the position of each cavity gate and the size of the gate point are the same and the length of the runner is the same. To ensure uniform molding conditions in each cavity.

2. For multi products and multi cavities use non-equilibrium runner and gate point, the size of the nozzle or runner should be adjusted according to the distance of the flow to ensure that the cavities are filled as much as possible.

3. In order to reduce heat and pressure loss, the runner should be as short and straight as possible, and the radius should be added at the corner to ensure smooth flow. The surface of the runner must be polished with more than 600# sandpaper. If the part is mirrored, the runner must be polished with 1000# sandpaper.

4. The gate system should be designed cold slug well to prevent cold material entry into the cavity and affect the quality and appearance of the parts.

5. The gate system must be vented to ensure that the plastic melt fills all corners of the cavity, so that the cavity gas can be discharged smoothly.

6. The gate system should be able to prevent the plastic parts from shrinking mark, deformation, dimensional deviation and other defects. The gates are convenient to cutoff or cut automatically and do not affect the appearance of the product.

7. In order to improve the mass production efficiency, it is necessary to minimize the subsequent processing of the plastic parts when designing the gate. Automated mass production, when the gate is taken out, the robot is used as much as possible to shorten the cycle time.

8. For the plastic injection molding gate design, the diameter of the root should be no smaller than the runner. For materials with high brittleness such as PS, a double-sided 3° draft angle should be used. Preventing the breakage of the sprue and runner, while the runner breakage will cause trouble for mass production.

9. Making runner into a circular or U-shaped that is easy to process.

10. The design of the gate system should take into account the amount of runner material. To save costs and eliminate waste, the weight of the runner is controlled below 25% and cannot exceed 50% (special consideration for special parts).

11. When there are multiple injection points on a product, the influence of the size and position of the welding line on the strength and appearance of the product should be considered.

12. For a multi-cavity plastic mould, reasonable, symmetry and compact positioning is able to prevent the eccentric load, reduce the mold base dimension and the tonnage of the molding machine.

13. For a multiple products mould which is also called family mold, the size of the gate must be adjusted according to the plastic parts dimension to ensure that each product is filled simultaneously.

14. For the complicate product, it's necessary to make mold-flow analysis to help design a good runner system and gate position.

Design standard for Sprue:

1.Injection molding machine nozzle and sprue matching

The spherical surface SR of the mold sprue should be 1-2MM larger than the nozzle SR of the injection molding machine. The SR of the nozzle can be found in the specifications of the injection molding machine.

Attention: When designing the mold, check the length of the nozzle of the molding machine that can be inserted into the mold. Should make proposal if have to use the extended nozzle.

2.Sprue diameter ⌀D setting

The sprue D should be 0.5mm larger than the the nozzle of the injection molding machine.

3.To shorten the sprue, we have to:

A.For two plate mould, sprue should be sunk in to the A plate (except for special customer requirements).

B.For three plate mould, big spue bush is must if the sprue length is 25mm or more.

C.Plastic parts with appearance requirements and other special requirements use hot sprue.

Design standard for Runner:

1.Type of runner.

A.Round runner.

B.U shape runner.

2.D series: 2 2.5 3 3.5 4 4.5 5 6 7 8 (10 12 reference use)

3.The runner diameter setting

For PE, PA, the diameter can be small. For PC, PMMA, the diameter value can be a large value.

Estimation diameter according to experience

4.Precautions

A.In the U-shaped runner, the size of the runner can be changed by

adjusting the H value.

B.Use round runner whenever possible

C.The runner must be thicker than the section of the subordinate

runner (see table below), if the secondary runner increases,

D1 diameter can be reduced according to the actual situation.

Design principles for common gates:

The form, position, size and number of nozzles should fully meet the requirements of mold processing and parts production.

1.Direct gate

1. Low pressure loss, easy to fill
2. The pressure at the gate is large, which will cause deformation.
3. It is difficult to remove the nozzle
4. Common gate
5. Easy mold processing
6. Correction is easy
7. Thin and long barrel products should not be used.
8. It is necessary to take care that whether the subsequent processing of the nozzle is convenient and whether the residue after processing will affect the appearance and function of the product.
9. Pin point gate
10. Flexible to select the gate location.
11. Small residual stress near the gate
12. After the mold is opened, the gate can be pulled off by itself. The traces left on the plastic part are not obvious, and the appearance of the surface of the plastic part is not affected.
13. The flow rate of the molten plastic flow through the gate is increased, and the frictional force acts to increase the temperature of the plastic stream. In this way, a plastic part with a clear shape and a glossy surface can be obtained.
14. Injection pressure loss is large, which is not good for plastic molding.
15. The mold structure is more complicated, and the double parting line mold (three plate mold) is generally used to remove the sprue.
16. Because the high flow velocity near the gate, the molecules are highly oriented, and local stress is increased, which may cause cracking. Therefore, without affecting the function of the plastic part, increase the wall thickness of the plastic part opposite the gate.

H.Warpage wil occur when a large plastic part adopts a point gate, so multiple point gates should be used at

the same time.

4. Sub-gate
5. Gate can be located inside or outside of the plastic product, the gate is usually located at the bone position of the injection molded product, the gate is concealed and does not affect the appearance of the injection molded part.
6. Small gate mark.
7. Gate is cut automatically.
8. There is a problem of large pressure loss.
9. Large flow resistance.
10. Fan gate
11. Good liquidity.
12. Can be evenly filled to prevent deformation of plastic parts.
13. The plastic parts look good.
14. Gate is not easy separate.
15. Large gate residue
16. Suitable for large and thin-walled plastic parts.

Slug well design

The location of the slug well is generally designed at the end of the sprue and runner.

That is, the first place where the melt plastic arrives, and venting is must added.

The design of the slug well varies depending on the different gate type.

Ejection of sprue

Normally, designer should have a thorough understanding of material properties, choose the most suitable solution.

The Principles of parting line plastic injection molding Design

1. The part with coaxiality requirement should be formed on the core side. If it is formed in the cavity and core side, it will be difficult to ensure the coaxiality due to the inaccurate clamping.

2. When selecting the parting surface, the dimension difference between the ends of the plastic part due to the draft angle should be reduced. The parting surface should be selected as much as possible without affecting the appearance of the plastic part and is able to meet the requirement of appearance. The split line and miss-match shall be submitted to the customer for confirmation;

3. The distance between the plates: the determination of the parting line should ensure that the mould cavity and core opening strokes are the shortest;

4. Should avoid the core pulling mechanism as much as possible, if it is impossible to avoid the core pulling, the pulling distance should be as short as possible, and try to make the slider all in core side;

5. Since the locking force is small when the inclined slider is closed, for a large plastic part with a large projection area, the parting line of the large projection area can be placed on the main plane after the cavity and core clamped, and the smaller projected area as the lateral parting surface, otherwise the locking mechanism of the inclined slider must be very large, otherwise, the burr is occurred due to non-tight lock.

6. The determination of the parting surface does not affect the normal opening of the injection gate system, especially the two plate mold with the multi-cavity parting surface.

7. In order to help the venting of the mold, the parting surface is as close as possible to the end of the plastic material stream.

8. The overall structure of the injection mould should be simplified, the number of parting line in mouldis minimized, and a straight parting line is used as much as possible. Should also consider whether the mold is easy to machining and process, easy to take out the finished plastic part, the parting surface should be selected as much as possible on the ridge of the plastic part.

9. Convenient installation of metal inserts.

10. Keep the product in the core side as much as possible and make sure there is enough position.

11. Sharp corners should be avoided in the parting line, as sharp corners will affect the life of the plastic injection mould. Therefore, parting line in plastic designshould check very carefully. If it cannot be avoided, send a proposal to the customer whether the product can be modified.

Types of Worm Gear Slewing Drive

According to the form of the variable speed transmission of the slewing drive, it can be divided into a tooth type slewing drive and a worm drive slewing gear, inheriting the respective characteristics of the slewing gear drive and the worm gear drive, and the two slewing drives can be adapted to medium and high speed and low speed applications respectively. In terms of carrying capacity, the worm-and-worm type performs better than the gear type, and its load carrying capacity, deformation resistance and transmission rigidity are further improved when using an envelope worm drive, but the efficiency of the worm-gear type slewing drive is Inferior to the toothed rotary drive. According to the openness of the slewing drive transmission mechanism, the slewing drive can be divided into open type and closed type. Generally, the open structure is mostly used in applications where the environment is too harsh, the maintenance and maintenance cycle is short, and the open structure is more convenient for the machine. Inspection, maintenance and maintenance are also easier to replace. Closed structures provide a longer maintenance lifecycle where environmental conditions do not change much and are below the level of environmental pollution below medium.

The built-in OLED screen can display a variety of adjustable parameters such as: Motor Strength, Follow Speed, Smoothness, and Deadband (helps prevent unwanted gimbal movements). These adjustments can be made directly on the WEEBILL-S without using the downloadable app. A built-in auto-tune function will tune the WEEBILL-S to mounted camera, providing the most efficient use of power and allowing your WEEBILL-S to run up to 14 hours on a set of interchangeable 18650 batteries, and the WEEBILL-S can power select cameras. Your camera mounts via the two-in-one Manfrotto/Arca-Swiss quick-release plate, while newly designed axis locks make balancing your camera faster and easier. The gimbal supports a full-range POV mode, Vortex mode (for 360-degree barrel rolls), Go mode for extremely fast action, PF mode (pan follower), F mode (follower), which has all axes follow your movements, and L mode, which allows you to mimic jib shots. Additionally, the Zhiyun ZY Play iOS/Android mobile app enables Panorama, Timelapse, Motion Timelapse, and Long Exposure Timelapse shooting.

An optional Image Transmission module mounts directly under the quick-release plate and transmits video signals up to 1080p30, allowing you to livestream from your gimbal. It works not only as a transmitter, but, incorporating a motion sensor, it allows for precision control. The second supported mobile app, ViaTouch 2.0, takes advantage of this, allowing you to connect with your smartphone, camera, and gimbal together electronically so you can adjust settings and control your set up from a smartphone. When coupled with the SmartFollow 2.0 module, sold separately, you can track objects precisely from your smartphone, without needing to mount your smartphone on your gimbal. The WEEBILL-S supports up to three devices wirelessly, including smartphones, tablets, and monitors. A third app, Sync Motion, interfaces with the Image Transmission module and allows real-time monitoring plus synchronous motion control for an immersive FPV experience.

Aquarium landscaping is an art. It creates a mini-world, a living ecosystem. Regardless of whether it is from moss on rocks, flowers from the shore, or algae and fish from the water, you need to consider it during the landscaping process. If you want to make a fish tank, you need to know the methods of aquarium landscaping. So what are the common methods of aquarium landscaping? Let’s take a look together.

What are the common aquarium landscaping methods

1. Ladder aquarium landscaping

This method is suitable for wall-mounted fish tanks. The basic shape is a step-by-step setting method from the background water plants to the foreground.

Critical notes: Put matching elements first, such as stone or driftwood. Pay attention to the texture of the material when placing it, and present a regular rhythm on the irregular material. The same pieces of wood and stone can produce different effects at different angles. The matching elements and water plants must be connected together without interruption to have a continuous overall sense. In the beginning, some plants with a faster growth rate can be planted in the foreground, and plants with a slower growth can be planted in the front and middle scenes. Except for the foreground grass, each kind of water weed is planted in clumps as much as possible. It is best to have only one clump of the same kind in the aquarium. The size and arrangement of each clump of plants are as irregular as possible, so as not to make the landscape too rigid. In principle, the ladder aquarium landscaping method gradually increases from the foreground to the background, but it can also be decorated with a few tall but less dense water weeds as the foreground, which can better show the three-dimensional effect of the landscape. You may need a set of tools for aquascaping.

2.Double-sided set method of aquascaping

Most of them are set techniques that can be viewed on both sides in the aquarium with compartment-style landscaping.

Critical notes: The principle of this method is the same as that of the ladder landscape method, but because both sides of the ornamental are taken into account, both sides must have beauty during landscaping. The middle line of the fish tank can be used as the location of the background grass, and the middle and foreground grass is planted on both sides, so that the layering and three-dimensional sense of the landscape can be more prominent, especially in fish tanks that are not very wide. The technique can more show the interestingness of double-sided aquarium landscaping.

3.Aquascaping with a three-dimensional fish tank

In addition to enjoying the scenery under the water, there must be scenery on the water surface.

Critical notes: Usually, an open-type fish tank is used together with a ceiling-mounted hanging lamp to better show the growth aesthetics of a three-dimensional aquatic landscape. When setting the scene, you can use more watery and floating water weeds, so that you can better enjoy the pleasure of changing the landscape in and out of the water. The three-dimensional aquatic landscaping fish tank is a more difficult landscaping method because it requires a higher level of configuration and there are more problems to consider when landscaping.

Precautions for fish tank landscaping

In the landscape design of aquatic fish tanks, sunken wood or aquarium landscape rock is often used as the accompanying scene. If there are no sunken wood or stones in the small plants, the scenery of the plants will appear stiff and rigid; with them, the scenery of the plants will become more natural and attractive. Therefore, sunken wood and stones have become indispensable companion elements to water plants.

Sunken wood and stubble in forests, mountains or swamps are slowly weathered through long-term sun exposure and wind and rain. Common sunken wood from Brazil is collected from moist or swamp areas. The surface of the material is beautiful, but the texture is relatively soft. The sunken wood made in the Philippines is very hard. Because it is heavier than water, it soon sinks to the bottom. The internal material also does not decay, which is one of the most ideal landscape materials.

The sunken wood set off the water and grass scenery. Although it has played a great role, it has its shortcomings. The reason is that when put into water, it changes the pH of the water, which is bad for the growth of water plants. Stone is also an ideal companion element. It is much more convenient to collect than sunken wood, but it also has disadvantages. It continuously releases alkaline substances into the water and changes the pH of the water. However, it is suitable to be used as companion material for banyan aquatic plants, because banyan aquatic plants are adapted to live in a limestone water environment.

Round concave mirrors are catoptric imaging. Mirrors( including convex) are reflecting back for imaging rather than get through the light, ray of light follows the law of reflection, that is what we called convergence. They always gather the light that shoot to the surface, ray of light that is entered parallelly will be focus on the spot again, ray of light is reflected from different angles because of different directions of surface normal. Round concave mirrors can not only focus parallel ray of light on the spot but also reflect parallel light from spot.

The diagram of a round concave mirror shows focus, focal length, centre of curvature and principal axis. Concave mirrors or gathering mirrors will deflect reflected ray of light. Concave mirrors will have different images because of the different distance between objects and mirrors, which is different from convex mirrors.

Round concave mirrors don’t have chromatic aberration because they are catoptric imaging, this advantage is can’t be compared with any lens. The resolution ratio is in direct proportion to the clear aperture of objective, it is difficult for the production of large aperture lens while concave mirrors that made according to reflection principal are easier. Therefore, round concave mirrors are always used for producing telescope.

The existing laser technology has always had a short board, which can only emit light of a single wavelength or narrow band. How to expand the frequency of the laser forming ultra broadband, super straight, ultraviolet, visible and infrared wavelengths of coherent white light laser, is still a human unfulfilled dream, it is a worldwide problem of science and technology. This is because the laser optics is composed of optical resonator, gain medium and pump source. The wavelength of the laser is determined by the energy level structure of the atoms, molecules or ions in the gain substance.

Because the natural laser crystal material has a great limitation on the gain frequency range and gain bandwidth, the laser can't produce any wavelength of laser.

Will the perfect white laser be created? What changes and developments could it bring to the application of lasers?

1. The sun light

It is known to all that all things grow by the sun, and the sunlight brings light and heat to the earth. The familiar sunlight is a kind of white light, and its spectrum covers ultraviolet - visible - near infrared - mid-infrared bands, as shown in figure 1, In the visible light band (400-700 nm), the radiation energy is strongest, covering seven colors of red, orange, yellow, green and blue, and continuous distribution and transition in the spectrum. Because the sun is white, rainbows are often seen in the sky after rain, or the sunlight passes through a glass prism through seven colors of light (figure 2). This is a common experience in everyday life.

One of the things that people are less familiar with is that sunlight is a completely incoherent light. In terms of spatial coherence, the sunlight cannot be straight and highly divergent. In terms of temporal coherence, there is no phase correlation and locking between different colors of sunlight. So sunlight can only be used to generate energy for heating, water heaters, solar cells and so on.

But the use of modern science and technology, such as the use of sunlight to transmit information, seems to be out of the question.

laser

The spectral distribution of sunlight. The spectrum of solar radiation including the sun itself, the spectrum of sunlight entering the earth, and the spectrum of sunlight reaching the sea level due to the absorption of atmospheric water and carbon dioxide.

2. The advantages of light and its application

White light laser light source, short wave laser light sources and continuous laser light compared with the ordinary white light, such as sunlight, incandescent lamp, white LED lamp, etc.), it has the advantages of high brightness, high peak power, wide frequency range etc. In the fields of scientific research, defense military, lighting, communication technology, information technology, industrial production, biomedicine, environmental detection, etc.it got a lot of attention.

White light, as a kind of new laser light source, it has a variety of advantages of good directionality, high energy density, super continuous spectrum, great bandwidth, the center of the flexible wavelength, high degree of coherence time and space. This will greatly expand the function and application scope of laser technology. The white light laser or the solar laser is the completely coherent light, not only the height of the laser beam, but also the very small region. Different color between amplitude and phase locking completely, by regulating the amplitude and phase, it can change the time of laser pulse shape follow one's inclinationsly, and produce very short pulse width (femtosecond and the femtosecond laser pulses. Such a solar laser will have the potential to realize the focus and convergence of light energy in space and time. It releases energy in small areas and very short periods of time to form extremely high instantaneous power density.

Our client base spans across defense, security, bioengineering, pharmaceutical, institutional, industrial, and research industries worldwide. We specialize in DFM (optical design manufacturing) input from rapid prototyping to volume production. Our comprehensive metrology coupled with cost-effective philosophy can help Hyperion customers obtain a competitive edge in the global market.
