Good Initiatives: Which Socially Oriented NGO Projects Won the Moscow Mayor's Grant Competition?

Translation. Region: Russian Federation –

Source: Moscow Government – Moscow Government –

An important disclaimer is at the bottom of this article.

To discover talents, promote a healthy lifestyle, and preserve the memory of generations—the capital's non-profit organizations (NPOs) care for children and adolescents, people with disabilities, special military operation (SMO) participants, and their families. They host creative events and sporting activities, and share stories about our country's achievements and family values.

Such projects receive support annually Moscow Mayor's grant competition for socially oriented non-profit organizations.

"Over the past five years alone, the competition has received more than 4,300 applications. The authors of 1,135 initiatives have won. The most popular categories are 'Youth of Moscow,' 'Our Heritage,' and 'Healthy Lifestyle and Sports,'" she noted.

Natalia Sergunina, Deputy Mayor of Moscow.

Just recently, at the end of September, it was announced results for 2025: 229 of the best were selected from more than 700 applications. Almost a third of the winners received grants for the first time.

After the competition results were announced, a mos.ru correspondent spoke with the project authors and learned what ideas they will bring to life.

Football in every yard

The autonomous non-profit organization (ANO) "Youth Initiative" will use a grant to give Moscow residents the opportunity to make their everyday lives more active. This year, it won the "Healthy Lifestyle and Sports" category with its "Football in Every Yard" project and will begin hosting open matches as early as spring 2026. Muscovites aged 16 to 35 are invited to participate.

From April to June, we will hold matches at district stadiums and courtyard football fields, and at the end of all the games, we will organize a final tournament. Our main goal is to show Muscovites that sport is accessible to everyone, and thanks to the capital's well-developed infrastructure, it's possible to play close to home. The tournaments will also allow you to master the ball game, spend time outdoors, make friends, and perhaps even make sport a regular part of your life and pursue it professionally. Denis Uvarkin, CEO of the ANO "Youth Initiative"

Pre-registration will be available for participation in the competition. Registration will open on the project's social media in March 2026. The competition will be held in seven administrative districts of the capital. Invited referees will explain the rules of the game to participants and monitor their compliance. The grant will be used to purchase sports uniforms, protective equipment, balls, and bibs—bright vests that allow players from different teams to be identified by color on the field. The grant will also be used to purchase gift sets and souvenirs for future match winners.

"Thanks to grants from the Moscow Mayor, even the most charitable projects can be made more vibrant and ambitious, attracting more participants. This is a tremendous support. At the same time, the capital has created all the conditions for the development of public initiatives. NGOs receive financial support from the city, space for work, and assistance in creating platforms for sharing experiences—coworking spaces," Denis Uvarkin emphasizes.

Bringing generations together

The "Cultural Codes of Young Moscow" project, run by the "Happy Family" counseling center, also received a grant. The funds will be used to organize events commemorating memorable dates and supporting family values.

In 2025, our center will celebrate its 25th anniversary. Throughout this time, we've regularly participated in competitions and have won several, which motivates and inspires us, giving us the strength to invent and create. Without grants, we wouldn't have achieved such a scale and been able to realize all our ideas. This year, we won in the "Youth of Moscow" category, and as part of the "Cultural Codes of Young Moscow" project, we'll be holding online lectures, quizzes, and quests, inviting young Moscow residents to talk about their libraries, schools, and courtyards—the little corners of the great capital they know. This will allow others to learn something new about the city. Irina Korchagina, Creative Director of the "Happy Family" Consulting Center

For example, a major event awaits project participants this summer. For Russian National Flag Day, celebrated on August 22, online lectures will be prepared for them about statesmen who influenced the course of history. To participate, please contact the organizers atthe project's social networks.

"People of all ages will be able to participate in the events. This will bring together generations, introduce children and adults to our country's culture and folk traditions, and help them delve deeper into history," adds the mos.ru source.

How teaching experience helps create and work in NGOsRaces, film screenings, and exhibitions: NGOs invite residents to autumn eventsSince the beginning of the year, more than 660 events have been held in district NGO coworking centers.

About the heroes of the SVO

Another winner of this year's competition is the ANO "Directorate of Sports and Entertainment Events 'Vsport'." The team will use the grant funds to implement the project "Moscow Remembers: Stories of the Heroes of the SVO."

We won the "Our Heritage" category. We want to preserve the memory of the defenders and support their families, so we decided to create a digital platform featuring video interviews, biographies, and photographs of SVO participants from Moscow. To do this, we'll interview them and their loved ones: we'll learn about the childhood and development of our heroes, their character and qualities, and how they distinguished themselves in battle. Alina Vorobyova, Director of the ANO "Directorate of Sports and Entertainment Events 'Vsport'"

Volunteers—schoolchildren in grades 8–11, and university and college students—will interview the subjects and their families. A preparatory course will be organized to teach the students how to conduct interviews.

"Over 500 volunteers will participate in the project. Thanks to the grant, we'll purchase voice recorders and microphones, branded folders, and badges for them. We'll also organize meetings where we'll explain how to conduct interviews, take high-quality photos, and digitize photographs from the subjects' family archives. After each interview, a video version, along with photographs and the subject's biography, will be uploaded to the platform," emphasizes Alina Vorobyova.

In addition to the digital archive, the project's creators will create paper albums and half-meter-long plasterboard panels. They will feature photographs and biographies of Moscow soldiers who defended their homeland with their lives and never returned home. The albums will be given to the families of the fallen, and the panels will be donated to Moscow school museums.

Find support in creativity

The "Gift of Sunlight" charitable foundation is implementing a project to support the families of SVO participants. It won a grant competition in the "Family Moscow" category.

Thanks to the grant, we're implementing an educational project for the wives of SVO participants, "Workshop for Development and Growth." We've already run programs for the families of our defenders. While speaking with mothers—the spouses of special operations soldiers—we learned that they wanted to learn new skills. We decided to create a creative handicraft course for women, where they can learn sewing and knitting. The grant funds will be used to purchase modern sewing machines and steamers, mannequins, thread, fabric, and other materials. Svetlana Myshkina, project coordinator at the "Give Sunlight" charitable foundation.

The team plans to launch the project in March. Free classes will be held on weekends at the charity's family center on Otkrytoye Shosse (Building 23, Block 5) until the end of December. The final event will be a fashion show: the project participants will walk the red carpet in outfits they sewed during the classes.

The handicraft course will be complemented by short lectures from invited speakers on a variety of topics. Experts will reveal makeup and self-care secrets and explain how to monetize a hobby. Our goal is to create a space for participants where they can learn new things, unleash their creative potential, and take a break from worries and anxieties. We are grateful to the city for its support. Grants are a great help to charitable foundations. They allow us to grow and help those in need. Gulnara Shvedova, Vice President of the "Gift of Sunlight" charitable foundation and project curator

Support the work of the fund Give me some sunshine Any user of the charity service canmos.ruAnyone can also make a donation and help those in need: select one or more nonprofits and make a transfer.

Los Angeles, Oct. 13 (Xinhua) — American company SpaceX launched a rocket carrying a prototype of the Starship spacecraft on Monday for its 11th test flight.

The rocket lifted off from the Starbase launch site in Texas at around 6:23 p.m. Central Time (11:23 p.m. GMT).

Shortly after liftoff, the Raptor engines ignited during hot stage separation. The Super Heavy booster made its planned splashdown in the Gulf of Mexico, and the Starship upper stage completed its climb and entered its planned passive flight phase.

During the launch, the spacecraft released eight simulated Starlink communications satellites from its cargo bay, which are following the same suborbital trajectory and are scheduled to burn up upon reentry.

After just over an hour of flight, Starship splashed down in the Indian Ocean.

SpaceX said the flight test aims to gather data for the next-generation Super Heavy launch vehicle, intensively test the vehicle's heat shield, and practice maneuvers that simulate the upper stage's approach to landing for future pad-return missions.

A designer of nonlinear models of composite materials has been developed at NSU

Translation. Region: Russian Federation –

Source: Novosibirsk State University –

An important disclaimer is at the bottom of this article.

Scientists at the National Technology Initiative (NTI) Competence Center for Modeling and Development of New Functional Materials with Predetermined Properties (CNFM) at NSU have developed a Nonlinear Modeling Tool for Composite Materials. A mockup of the tool and prototypes of its individual modules are currently being tested.

The new software will enable engineers to build highly accurate models that account for nonlinear material behaviors such as viscoelasticity, elastic-plasticity, damage accumulation, and induced anisotropy. The computer models generated by the Designer will enable more efficient use of the strength reserves of functional materials. The development will find application in the aircraft and engine manufacturing industries, the oil industry, and medicine. The Designer was developed with financial support from the NTI Foundation.

"When computer modeling the deformation and failure of a complex component or mechanism, it's not enough to simply create a geometric model. It's also necessary to 'explain' to the computer program the materials used to construct the structure being modeled and the properties of these materials. For a long time, engineers calculated processes using simple linear models, as nonlinear models are a much more complex, yet more modern, approach. Importantly, nonlinear models are significantly more accurate than linear ones. They allow for more efficient use of the material's strength reserves, thereby reducing the cost and weight of the product and increasing its competitiveness," said Alexey Shutov, Doctor of Physical and Mathematical Sciences (Dr. habil.), a leading researcher at the NSU Center for New Functional Materials, regarding the relevance of this development.

An example of a linear model is Hooke's law, which everyone knows from school. Hooke's law states that the deformation occurring in an elastic body is directly proportional to the load applied to it. In other words, the harder we pull a spring, the more it elongates. The problem is that highly loaded materials behave nonlinearly: they can plasticize, creep, harden, or, conversely, accumulate damage; materials seem to remember what happened to them in the past. These are more complex effects that are poorly covered in standard engineering courses and that cannot be described within the framework of linear models. However, full-fledged nonlinear strength calculations are the prerogative of scientists studying solid mechanics—an interdisciplinary field at the intersection of materials science, mechanics, and computational methods.

"The idea behind our software is to make these competencies accessible to engineers so that the processes and technological steps required to build, configure, and implement a nonlinear model are automated. First, our Designer creates a nonlinear model signature—its fundamental description. Next, the Designer allows for the integration of experimental data, which is used to configure the model and test its predictive ability. After calibration, a computational algorithm is generated that implements the model in C. The resulting algorithm, in turn, is integrated into computational systems used to analyze the strength of products at the executable code level. Such systems include Ansys, MSC.Marc, Abaqus, and Logos," Alexey Shutov explained the development concept.

The model builder developed at NSU also addresses educational challenges, raising the level of competencies and culture in the field of nonlinear modeling.

"Our Designer includes an interactive model reference. The user can specify the task parameters, and the interactive reference will suggest which class of models to use to solve a specific problem, what experimental data is needed for calibration, and what the engineer can expect when applying such a model," added Alexey Shutov.

In construction and mechanical engineering, there are acceptable safety factors incorporated into structural design. A large safety factor is the price paid for ignoring the factors that influence a structure's performance. Nonlinear models generated by the Designer allow for more accurate calculations, and as a result, products can be designed with smaller safety factors. This is especially important for the aerospace industry, where structural weight is a key consideration.

The development of more accurate nonlinear models is also relevant for aircraft engine manufacturers (designing turbine blades and other highly loaded components), since in a competitive environment, the main focus is on reducing weight while simultaneously increasing efficiency, reliability, and engine power.

"Engineers have little experience working with modern, advanced materials, and they often lack sufficient experimental data. Gaining such experience through physical testing and experiments is an expensive and time-consuming process. For example, to implement a silicon carbide-based composite, it's necessary to understand how it will behave at a given temperature under a wide variety of loading scenarios, its service life, and how quickly it will degrade when a nick or crack appears. Solving these problems requires computer modeling and digital twins, which means high-precision nonlinear models are also needed," explained Alexey Shutov.

The designer developed at NSU can be used not only to simulate processes that will occur with existing materials but also to design new ones. For this purpose, the designer has a submodule—so-called surrogate models of representative volumetric elements. Essentially, it allows for the construction of complete digital twins that explicitly account for the microstructure of a composite material. Representative volumetric elements make it possible to predict the mechanical properties of new materials that have not yet been developed and tested based on the properties of individual phases, while surrogate models speed up calculations by hundreds of thousands of times.

"We also see great potential in the field of biomechanics. For example, Pavel Petrovich Loktionov's group is actively developing blood vessel prostheses at the Institute of Chemical Biology and Fundamental Medicine of the Siberian Branch of the Russian Academy of Sciences. From a mechanical standpoint, these are high-tech products made from functionally graded materials. It's important to calculate the mechanical properties of a prosthesis: on the one hand, it shouldn't be too rigid, otherwise there will be problems with implantation, and on the other, the prosthesis can't be too flexible, otherwise it will lose stability and cause an aneurysm. Therefore, it's necessary to select the optimal properties of the prosthesis, for which a mathematical model of the composite material from which the prosthesis is made is useful. Our Designer was created with an eye toward solving such important applied problems," added Alexey Shutov.
