Ancient China’s Tiger Queen

Archaeologist Sarah Milledge Nelson, alumna of the University of Michigan, distinguished university professor emerita at the University of Denver, and award-winning author of scholarly works, has just published Ancient China’s Tiger Queen, her third novel. In it, Nelson tells the story of a real queen of the Shang dynasty in ancient China, who was also a general, a shaman, a landowner, and the mother of three children. Nelson talked with UMMAA about the whys and hows of writing fiction as an archaeologist, and what novels can accomplish that archaeology cannot.

Nelson’s first and second novels are Spirit Bird Journey and Jade Dragon. Although the three books are not a trilogy, they are connected, explained Nelson.

“The theme that relates them is strong women leaders,” she explained. “And they go in chronological order: Early Neolithic, Late Neolithic, and Bronze Age." Tiger Queen takes place in the Shang Dynasty, which was during the second millennium BCE.

Though they are fictional tales, her novels all have unassailable foundations in archaeology.

“I have invented as little as possible,” she said. “I made use of both archaeological and written materials. I wanted to be able to reply to those skeptical of the women leaders in the stories. To those who have asked, “How do you know the chief was a woman?” my reply is simply, how do you know it’s not so? Using the archaeological evidence, a story with a woman chief is just as plausible as a story with a male chief.”

Nelson’s first two novels are based on excavations she participated in. Spirit Bird Journey is based on her work at Osanni on the west coast of Korea. That novel was translated into Korean, and for those who want to visit it, there is a museum at the small village nearby. The second novel takes place in northeast China, at Niuheliang, which is called the Goddess Temple for a sculpture fragment made of unbaked clay: a female face inset with green jade eyes.

Ancient China’s Tiger Queen is based on the first readable Chinese writing—that of the oracle bones—and the grave of Fu Hao, a consort of King Wu Ding of the Shang Dynasty. Although Nelson was not part of the crew at this site, she visited it three times and spoke with Dr. Zheng Zhen Xiang, the director of the first excavation of Fu Hao’s tomb, and two Anyang archaeologists still working there, Jing Zhi Cheng and Tang Ji Gen.

Nelson read and taught for years about the Shang dynasty and King Wu Ding’s most important queen, and she wrote and rewrote the novel over a decade.

The main character of Ancient China’s Tiger Queen is Lady Hao (fu is the Chinese word for lady, Nelson explains), who (in the story) introduces horses and chariots to Shang from her homeland to the north, and thus allows her husband, King Wu Ding, to establish an empire.

To help guide readers who are not familiar with the history of Shang, each chapter begins with a quote to situate the story in the archaeological discourse about the site. Author’s notes are added at the end to explain some debatable interpretations of the evidence and to allow students to critique those choices. For example, nobody knows why or how horses suddenly appear in Shang.

“The origins of horseback riding in China are still in dispute,” Nelson wrote. “In fact, there is still controversy over the earliest horse riding in Central Asia, which presumably antedated that of China by thousands of years… Horse bones are found in several sites in the Chinese Neolithic, especially the north and west, regions that would have been in touch with horse breeders on the steppes. This is the region where I have imagined Lady Hao to have been born and raised. But no one has yet studied how Neolithic horses were used, or even whether they were wild or domesticated.”

It’s not hard to see the dominant theme in Nelson’s work. In addition to three novels, Nelson has published ten scholarly books—including the classic Gender in Archaeology: Analyzing Power and Prestige, which is still selling and still cited after more than twenty years—and edited eight other volumes.

Nelson believes that archaeological explanations will always be about males until archaeologists are able to show that women were an important part of cultural evolution, and the agency of women is established and taken for granted. For the most part, when you say “the leader,” people think of a male, Nelson points out. She wants to put a dent in that assumption.

But despite her efforts, and those of fellow archaeologists, the rate of change has been slow.

“In terms of archaeology, I don’t think [gender] has been taken seriously by those who write grand theory,” Nelson said. “Very few women have made an impact on the field in terms of theory. Feminist/gender archaeology is still considered a fringe endeavor in many places.”

Frustrated with the lack of progress in gender archaeology, Nelson decided to try a different tack: try to connect with the public through novels about women in archaeology.

Best Free Drawing Software 2023

Drawing is fun. But drawing is also part of business. Today’s brands need recognizable aesthetics and icons. So, many artists turn to graphic design in their professional lives. To get more news about 2d construction drawing software, you can visit shine news official website.

Meanwhile, new and budding digital designers are hitting the scene all the time. If you’re one of them, you are looking to get started with free drawing software.This article will go over the kinds of drawing tools out there. Then we’ll compare the 12 best open-source or free drawing software, and even give a shout out to some premium versions with free trials.

Drawing software is divided into two main kinds. One of them is all about points, lines and shapes. That’s called vector graphics. The other is about pixels. That’s called raster images. Most industry-standard drawing software combines a bit of both.

Vector graphics
Vector graphics let you instruct the program about the relationship between points, lines and shapes on a canvas. The program knows the digital information connecting these things. This lets you enlarge up a vector image without losing quality. That’s because the program can just accordingly scale up the data between vector assets.

Vector drawing software often also includes a freehand drawing tool. This gives artists more freedom than with just points, lines and shapes. It lets artists be more expressive and creative.

Vector graphics are great for logos, icons and other symbols. It’s useful for designing websites and mobile apps too.

Raster images
Raster images are images broken down into individual square units called pixels. The individual pixel can only be changed as a whole. The smaller the pixels, the finer the detail of the image. The proof is that when you zoom in enough on a raster image, you can see the individual pixels, lines become jagged, and the image becomes blurry.

Raster drawing is a more common tool to begin with if the artist wants to create totally original drawings. In other words, it is more common for freehand illustrators. But as some vector software can include some freehand drawing options, raster software can include some vector tools.

Raster editing is also the main method of photo retouching. Photos are captured by software as they are. You can not change the underlying data that describes the image as you can with vector assets. But you can zoom in and edit or touch up large swathes of pixels at once.

Just How Tolerances Influence Injection Molded Plastics?

The tolerance stated in the plastic injection mold is an engineering requirement. In basic terms, they are allowable variants to the initial dimensions of the parts or the base dimension. As it is impossible to generate a product that purely abides by the base measurements, some leeway obtains factored into the design of items.To get more news about 2k injection molding, you can visit asm-mold.com official website.

This margin ensures that all measurements for molded products fit the setting up demands. For example, you may wish to produce products with a size of 2.8 mm. Nevertheless, attempting to produce them might end up with some of them gauging 2.6 mm.

What tolerances do is to establish minimum as well as optimum values for the production process in a way that ensures the product fits. In this case, the reduced limit can be evaluated 0mm while the ceiling is readied to 0.3 mm. By doing this, you are assured products whose diameters range between 2.8 mm and also 3.1 mm.

The important of tolerances
Generating plastic parts for your products calls for that their measurements fit perfectly. It’s very easy to offer dimensions for the type of components you want; obtaining them to have similar measurements to your requirements is a virtually impossible venture to achieve.

The type of making procedure you go for also has a terrific bearing on the high quality of completion product. Injection molding is among the most effective processes you can experience with standards like hubbub 16901 to name a few, but it’s still unable to produce parts with the right fit.

The only escape of such a scenario where it’s impossible to get an exact suit is to leave area for some distinctions in dimension. They don’t need to be major; they simply require not interfere with the item style. This is where tolerances are available in.

What Influences Tolerance?
The kind of polymer utilized throughout the creation of your items substantially identifies whether the tolerances are within acceptable limitations. As distinct polymers obtain injected into the plastic mold, they cool as well as shrink at different prices.

Despite the fact that these shrinkage rates can be quickly represented, completion product will certainly have different tolerance ranges and also discrepancies from the acceptable varieties. The array is a dimension of the difference between the biggest as well as tiniest measurements of measurements in the created batch.

Various other aspects that figure out tolerance consist of the style of the product, the intricacy of the style along with the atmosphere the injection molded parts will certainly be running in.

Minimum/Good Tolerances for Plastic molds
The great, or rather, minimal tolerances are established by the plastic polymer you choose to use for your products. These tolerances also can be found in various forms. For one, there are dimensional, straightness/flatness, and also hole diameter tolerances. They are also divided right into business tolerances and precision tolerances, which are greater in price.

Considered that an injection-molded physical tightening is a result of the cooling, the facet of temperature level decrease is influenced by various other aspects as well. They include the thaw thermal reading, the cooling price, the thickness of the part, the dimensions of eviction, as well as much more.

Furthermore, a section of the molded product that is thicker than an additional will certainly experience even more shrinking. All these variables are since even though it is possible to forecast the behavior of the plastic polymer you wish to be molded; the material will never ever act as anticipated 100% of the time.

The polymer concerned might likewise experience warpage. This is particularly real with parts that are non-uniform as they shrink at various rates in comparison to components that have uniform wall surface thickness. These non-uniform components can happen whenever the part’s design has a concern.

UFI Filters for Hyundai Tucson, the best-selling C-SUV in Europe

UFI Filters filtration technologies are once again confirmed as the winning choice of car manufacturers, Hyundai Tucson indeed mounts the UFI fuel filter as original equipment and was the best-selling C-segment SUV in Europe in 2022.Get more news about hyundai filter,you can vist our website!

According to data published by JATO Dynamics, a company specializing in the automotive business intelligence sector, 150,803 Tucson were registered in the old continent last year. Now in its fourth edition, the car from the Korean brand has confirmed itself as the most popular mid-segment sport utility vehicle over time. Thanks to the design of its lines and the reliability of the engine, it can count on the protection guaranteed by UFI Filters filtration systems, not only for the latest series, but from the second generation yet.

NEW GENERATION DIESEL FUEL FILTER: ECOFRIENDLY AND INTEGRATED WITH MULTIPLE FUNCTIONS
UFI Filters supply as original equipment the diesel filtration system for the 1.6 CRDi engine of the new Tucson, also for the mild hybrid version (MHEV). Compared to the previous version, the advantages of this new module are the integration of multiple functions and the lightness of the element given by the plastic materials and the cartridge in ecological material. Water presence sensor, ceramic material heater and pressure sensor are located within the same group sensor unit, located on the top of the filter. This allows for greater efficiency of the heat exchange.

The filter cartridge has high water separation capacity, produced according to the exclusive material in FormulaUFI.Stratiflex which separates the water particles based on the coalescence principle. Reinforced with an internal hydrophobic mesh, the filter blocks the water droplets marking them fall to the bottom of the module tank, where there is a draining plug. The water presence sensor signals precisely when it is time to empty the tank.

UFI FILTERS FUEL FILTRATION TECHNOLOGY
Thanks to its industrial site in Korea, UFI Filters can boast an historical partnership with Hyundai, since its second generation, Tucson in diesel version was equipped with the complete fuel filter made with the exclusive filter media in FormulaUFI.Stratiflex.

UFI module for Tucson model year 2015-2021 comprises an aluminum head with pressure sensor and a heater, while the filter body is equipped with a water presence sensor. This is all supplied inside a retainer to protect the system in an impact. The steel filter element encloses a dual-stage filtration system, made of FormulaUFI.Stratiflex: a first barrier for impurities and water formed by a cellulose-based media, a second made of hydrophobic mesh to eliminate residual water particles.

The guaranteed filtering efficiency is greater than 99% at 4 μm, while the water separation exceeds 90% according to ISO 16332 and the water presence sensor signals when it is necessary to purge the liquid collected on the bottom of the filter tank.

THE QUALITY OF THE ORIGINAL FOR THE AFTERMARKET.
UFI Filters thus confirms itself as the preferred brand of car manufacturers, chosen by 95% of vehicle manufacturers in the world. This know-how developed for the original equipment turns out to be one of the main advantages also for the aftermarket. In fact, the quality of the original product is also guaranteed by the independent spare parts network. The diesel filter for Hyundai Tucson second generation is available in the aftermarket catalogue with the UFI brand, under the code 24.123.00 and with the brand SOFIMA, under the code S 4123 NR. While the introduction of the eco-cartridge for Tucson last generation is under development.

The OWL Fishing Tool: How Low Can You Go?

While many diamond drillers enjoy fishing in their spare time, no one wants to go fishing on the job. Fishing is the process of removing down-hole equipment that has become stuck, lost, or broken off in the hole. It means that operations have ground to a stop and your productivity is being affected.Get more news about Bq Rod Shoe,you can vist our website!

There are a lot of reasons why a rod string can break. Often, the type of ground is the culprit and can cause your equipment to jam. Clay can swell when water is introduced, squeezing the drill string and barrel. Sand can collapse around the drilling equipment, causing high torque and stuck rods. Sometimes a drill rod can be dropped or the bit can melt and fuse to the rock. Whatever the cause, you will need to try and retrieve the rod, or fish for it. If your hole is deep, you will want to try to get whatever equipment you can from the hole so you don’t have to start over drilling a new hole.
There are different tools you can use but let’s focus on the OWL fishing tool. It is reasonably priced and effective. To use a fishing tool, you lower it into the rod string, well past the broken end. Once inserted into the fish, water is pumped into the rods. The pressure of the water on the internal piston of the tool forces the attached hardened keys down and outwards on the taper of the tool body, to positively engage the fish. The rods are then pulled back, further engaging the keys. Once rod weight is felt on the tool, water pressure can be released. The weight of the rods will now keep the jaws engaged.

Many drillers use a fishing tool but often wonder just how much rod can it pull up out of a hole. That question is hard to answer but a recent case illustrates just how durable and reliable the OWL fishing tool is when it comes to deep holes.

A customer was drilling for nickel in the Sudbury basin and had a borehole that was 2,300 meters in depth when the drill rod broke off at 1,800 meters. No one was sure whether the Owl fishing tool would be able to retrieve that much rod so deep in a hole but it is extremely durable and can fish out much more than you think possible. They figured they had nothing to lose because the fishing tool can be released if you’re not successful. That is a huge bonus.

Think for a moment how much weight that represents. It was a BQ rod. The weight of a 3 meter long BQ rod is about 40 lbs. and we had about 600 of those. So that would make 24,000 lbs. Then you need to calculate how much water was in the rods. There is 13.4 gallons of water per 30 meters, so about 800 gallons of water. A gallon of water weighs about 8 lbs. so another 6,400 lbs. for a total of about 30,400 lbs. That’s a lot of weight for a fishing tool to pull but it worked, and they ended up using the tool again afterwards.

The point of this story is that when tools are made well with quality materials they can do much more than you expect them to be able to do. Our technical team sees innovative solutions to problems on the drill site every day. They can be a very valuable resource when you encounter a drilling challenge so make sure you contact them if you need some creative thinking or advice. Remember our goal is to make drillers’ lives easier.
