Published: December 2021

Este artigo expõe uma investigação realizada em um curso de formação continuada sobre a temática Letramento Estatístico desenvolvido na modalidade a distância. O tema “Letramento Estatístico” se constitui cada vez mais uma demanda social, independentemente da área de formação e de atuação das pessoas. Estudiosos como Freire (1994), Gal (2005), Skovsmose (2008) e D’Ambrósio (2014) enfatizam a necessidade de formar cidadãos capazes de ler criticamente o mundo. Desse modo, a formação supracitada foi destinada aos profissionais de uma instituição de ensino superior privada que atuam na tutoria on-line de diferentes cursos de graduação. Este estudo teve por objetivo compreender as estratégias de intervenção de dois mediadores a partir das resoluções de uma situação de aprendizagem elaboradas pelos grupos de cursistas de uma das turmas. A metodologia, de caráter qualitativo, utilizou as respostas dos grupos disponíveis no Ambiente Virtual de Aprendizagem (AVA) do curso. Diante das soluções apresentadas, os dois mediadores relataram suas estratégias de intervenção, as quais foram descritas e analisadas à luz das teorias sobre a mediação e o ensino de representações gráficas. Por fim, esta investigação revelou que as estratégias em comum utilizadas pelos dois mediadores focaram em inserir os cursistas em uma postura ativa e reflexiva no processo de aprendizagem. Ressalta-se a importância de estratégias mediadoras voltadas à problematização, novos desafios e questionamentos que instiguem o cursista a conjecturar sobre suas ideias e a explicitar seu pensamento, favorecendo o desenvolvimento da autonomia para aprender no contexto da Educação a Distância (EaD).

The problem of religious unity in modern Kazakhstan
Authors: Vasic Bibigul , Begimbayeva Zhibek , Khibina Zada 
Published: December 2021

The respect for religious diversity that Kazakhstan promotes appears to be under strain at home. Kazakhstan’s legislation guarantees equal treatment of all religions, but acknowledges the historical role of Hanafi Islam and the Russian Orthodox Church. The purpose of the article is to highlight the results of an analytical and comparative study of religious communities operating in the territory of modern Kazakhstan. A comparative method is used as the main method in the classification, typology, assessment and generalisation of religious communities. In general, the presented analytical data should be related to comparative religious studies. Both are so-called traditional religions that have been present in the Kazakh territory for many centuries. Authorities seem unwelcoming of ‘new’ religious movements that have gained followers in Kazakhstan in recent years. However, due to the rise of religious extremism and terrorism around the world, religious tensions were found here. The study concluded that since gaining independence, religious activity in Kazakhstan has increased.

Published: December 2021

The study of the properties of blast-furnace slags requires an integrated approach, including various research methods. The purpose of the work is to substantiate the resource value of the Zaporizhstal dump blast furnace slag. The research methods were used: X-ray phase, petrographic, gamma-spectrometric analysis and electron probe microanalysis. The slag is dispersed into fractions, since the slag minerals have different hardness. Fractions (mm) were investigated in the work: >20 2.5–5, <0.63. X-ray phase analysis made it possible to reveal in the crystalline part of blast-furnace slag minerals that are technically valuable in the production of binders: 3CaO∙2SiO2, SiO2, 2CaO∙Al2O3∙SiO2, α-2CaO∙SiO2, 2CaO∙MgO∙2SiO2, α-CaO∙SiO2. Minerals akermanite, bredigite, pseudo-wollastonite have hydraulic activity. It is shown that the mass fraction of the amorphous component is half the mass of the blast furnace slag. The high content of substances in the amorphous state confirms the possibility of sorption of extraneous ions and compounds. The found elements Potassium, Sodium, Sulfur, Chlorine, Cuprum and Titanium are not part of the minerals. Slag contains less than 1% of the total amount of Fe, Ti and Cu, belonging to the 3rd class of hazardous substances. The maximum content of Potassium, Sodium and Titanium is typical for the fraction 2.5–5 mm. The most basic is the fraction <0.63 mm (pH 9.7), for the 2.5–5 mm fraction pH 9.1, the most acidic fraction >20 (pH 8.2). By the value of the toxicity index (4.3–5.4) and the III hazard class, dump blast furnace slag «Zaporizhstal» as a moderately hazardous waste can be used as a secondary raw material in the construction industry. The database on the content of natural radionuclides in technogenic raw materials has been updated. It has been proven that slag and its individual fractions contain natural radionuclides 40К, 226Ra, 232Th. The main contribution to the value of Сef is made by the 226Ra radionuclide, then by 232Th. The excess of specific activity is expressed for the 2.5–5 mm fraction. The I class of radiation hazard is defined, which allows the use of slag in construction without restrictions. Dump blast furnace slag «Zaporizhstal can be recommended in the production of inorganic binders « by the totality of chemical indicators.
DEVELOPMENT OF RESOURCE-SAVING TECHNOLOGY OF POROUS-HOLLOW CERAMIC STONES

Published: December 2021

A resource-saving technology of porous ceramic materials using low-quality non-sintering sandy loam as a basic raw material has been developed. Based on the analysis of the plastic properties of two- and three-component ceramic masses, including sandy loam, expanded clay and fuel slag in various ratios, it was found that the required level of their plasticity provides the content of the main raw material in the following range (wt%): fuel slag – 15 – 20; sandy loam – 50 – 65; expanded clay – 20 – 30. By the method of planning the experiment, the rational composition of the three-component ceramic mass was substantiated. This which contains: 62.5 wt. % sandy loam, 20 wt. % medium-sintering plastic clay as a plasticizer and 17.5 wt. % fuel slag of TPP as a porous agent. For the developed mass, the main technological properties were investigated, which made it possible to recommend the drying mode of the raw material – 60 hours, the optimal firing temperature – 950 °С. Such conditions ensure that samples are obtained without drying cracks and signs of deformation. Оn the results of dilatometric analysis of mass the rational mode of firing high-hollow semifinished products was designed. The firing mode provides for a 44-hour firing and a decrease in the heating rates in the areas of dehydration of clay minerals, direct quartz transition and intensive sintering of the mass, as well as a decrease in the cooling rate in the area of the reverse quartz transition. The proposed firing mode provides the degree of sintering and their properties necessary for ceramic materials. Based on the developed mass under the recommended drying and firing modes, porous ceramic materials with an apparent density of 1.48 g/cm3, a compressive strength of 18.2 MPa and frost resistance of 30 cycles were obtained. The developed materials belong to the group of conditionally effective, and if 50% of the voids are organized, they can be classified as effective.
Structural‑phase composition of a gas‑thermal coating of Fe‑Cr‑Ni‑Al pseudo alloy subjected to annealing

Published: December 2021

The structural‑phase state of the gas‑thermal coating made of Fe‑Cr‑Ni‑Al pseudo‑alloy in the initial state, as well as after annealing in the temperature range 550–650 °C for 20–60 minutes, has been investigated. It has been established that the phase composition of the Fe‑Cr‑Ni‑Al pseudo‑alloy in the initial state includes mainly Al and α‑Fe, and its porosity does not exceed 3–5 vol.%. Annealing of a thermal spray coating from a pseudo‑alloy at temperatures of 550–650˚C for 20–60 minutes leads to the release of iron‑aluminum intermetallic compounds Fe3Al, Al13Fe4 and Al5Fe2, an increase in hardness and porosity.
Shell Rounds the Corner on a Whale of a Task
Authors: Wright Blake 
Published: December 2021

Shell had a problem. It had just spent billions to bring its Appomattox find on line in the deepwater Gulf of Mexico (GOM). That development featured the oil giant’s eighth and largest floating platform in the region. The host semisubmersible weighed 125,000 metric tons—more than the largest aircraft carrier.
Shell lauded its ability to reduce project cost by 40%, based on experience gained from the development of its previous four-column production platforms in the US Gulf, including the Olympus tension-leg platform. It would transfer these learnings to its next project—the Vito find in about 4,000 ft of water, 150 miles southeast of New Orleans. The field could hold up to 300 million BOE.
At the same time the plans for Vito were being laid out, shale projects leapt to the forefront in the competition for capex dollars, and due to the comparative investment, they were winning. Industry success across the nation’s shale plays helped flood the market with oil, forcing the price per barrel down. Suddenly, spending big money on megaprojects offshore had lost much of its luster. For the US Gulf to reclaim at least some of its competitive advantage, fields could no longer be developed with massive, high-dollar facilities. A management mandate dictated that a new minimal, repeatable solution be found. After several years of study, a favorite emerged.
“The original concept of Vito was much larger,” said Kurt Shallenberger, Vito project manager for Shell. “The development was probably similar in size to the Appomattox project that Shell recently completed—a 40,000-ton topsides, and a 50-year field life with a sizable gas-reinjection component to it.”
Shell’s method for arriving at the new development scheme was dubbed “Minimal Technical Scoping”—the company would start with the absolute minimum scope and then justify additions upward. The project mantra was “Simpler is safer.” The results were a simplified topsides design as well as streamlined mooring systems for the host facility.
“The redesign took it down to what I call the sweet spot of semisubmersibles—around a 10,000-ton deck,” said Shallenberger. “You had seen examples of that with LLOG’s Delta House, Independence Hub, and others like that. That was the sweet spot to where multiple fabricators can build it, multiple yards can integrate it, multiple companies can install it—and you can generally get 100,000 bbl a day through it. Now you’re in a competitive environment for all the vendors rather than just the one guy in the world who can do this. That’s what really created the opportunity for Vito. We shrunk the size and scope down to a point where it could get to a breakeven price that is competitive with the onshore folks.”
According to Shell, the breakeven price for their minimal floater design is less than $35/bbl.
Shell locked up key vendors for Vito. Jacobs Engineering Group carried out the detailed engineering and front-end engineering design studies for the Vito topsides. Sembcorp would build the host and integrate the topsides and hull at its Tuas Boulevard yard in Singapore.
A New Recipe for Friction-Reducer Suppliers: Polymer Plus Frac Water, Minus the Cost
Authors: Rassenfoss Stephen 
Published: December 2021

The argument for making friction reducer on site is simple: only one truck is required to deliver dry polymer vs. three loads required for the same amount of liquid additive.
For Downhole Chemical Solutions (DCS), reducing the number of trips and the amount of chemicals needed to create a stable liquid by mixing it as needed on site reduces the average cost of a gallon of friction reducer by around 30%, said Mark Van Domelen, vice president of technology for DCS.
“The business is very cutthroat and competitive on the pricing of polyacrylamide. We can reduce the cost further on friction reducer,” using dry polymer, he said.
Polyacrylamide is generally described as the key component in friction reducers. Suppliers also add some ingredients to create a stable liquid and others that are supposed to improve performance. When DCS delivers dry polymer to a well pad to mix it on-site, the only other ingredient is water provided by the customer.
It has been a winning strategy change for the private company; it has grown rapidly, even during last year’s slump. DCS increased the number of mixing units from one to 16, and dry polymer sales have grown from 10% to 90%, Van Domelen said.
One of the company’s customers is John Blevins, the chief operating officer for Houston-based Hibernia Resources III and an early adopter who was a lead author of a paper on making friction reducer on site while fracturing (SPE 204176).
Blevin, who uses the words “friction reducer” and “polymer” interchangeably, is the rare C-level executive who likes to manage operations from a frac van at a company that normally completes one pad at a time.
The polymer is polyacrylamide. When Blevin works with DCS on a well, he purchases it directly from one of the few chemical companies that will produce the polymer based on his specifications. The price on the DCS invoice will be a price per pound that covers the cost of the polymer and the service.
At Hibernia, a small private-equity and employee-owned company, there is a powerful incentive to pay close attention to the details.
“When we spend a nickel, that nickel is divided among us at some point in time. If we are efficiently frugal, we are going to be better off in the long run,” Blevins said.
The paper, which was presented at the Unconventional Resources Technology Conference (URTeC), included a chart showing stage-by-stage costs, with the average cost for dry stages ranging from 27% to 31% lower than similar stages that were fractured using liquids.
The simplicity of the mix is a plus for Blevins whose company is especially focused on how chemicals are likely to react downhole.
“We did a 6-month study before we pumped anything in the ground to make sure we had the right combination” of fracturing additives, he said. “We do study nearly every well and every landing zone to ensure the chemicals used are compatible.”
