Iranian Knowledge-Based Company Produces Computer Power Supply Unit (PSU) with 7-Year Warranty

A group of engineers at a knowledge-based company in Iran have launched production of computer parts and equipment such as power supply unit (PSU) which are offered to the market with seven years of warranty.

“Case, power, mouse, keyboard, all-in-one personal computers (AIO PC) or desktop computers and motherboard are some the products of this company,” Kavan Morovati, one of the technicians in the knowledge-based company that manufactures computer parts in Iran said in an interview with local Iranian media.

Saying that their products have been produced in three categories of office, gaming and economical, the company’s technician added, “The motherboard produced in this company was designed after studying weaknesses of the existing products in the market. Among its disadvantages, we can mention the number of its MOSFETs. The MOSFET supplies power to the CPU and the higher their number, the higher the CPU output.”

Morovati described H510 mk, H610 mk, B560 md and B620 md among the models of motherboards produced in their company and pointed out, “These motherboards support 10th to 14th generation for users. The company's H510 mk model, which is lowest model of produced motherboards, has obtained the first ranking of the benchmark and is higher than Asus.”

Emphasizing that the motherboards produced by their company have been commercialized in the country, he said, "The warranty of our products is a replacement. Also in case that any part or any of our products that has reached the customers and has a problem is 24 months to 7 years will be replaced with no excuse."

“For example, with respect to displays, less than 5 burned pixels will not be replaced, but even with one burnt pixel in our displays, the replacement will be done,” Morovati added.

“The power supplies units (PSU) produced by this company are made in a way that if the system encounters a problem in terms of hardware or software in overload mode, it will detect the system temperature and turns off the system according to the system temperature and power operation until the system temperature increase does not occur,” he said, adding, “This feature does not exist in other power supplies units and causes the power to burn.”

Iran, WHO to Cooperate to Eliminate Hepatitis C

Iran and the World Health Organization (WHO) are due to set up a joint working group and cooperate in elimination of hepatitis C.

Iranian Deputy Health Minister Hassan Farshidi, in a meeting with WHO’s Assistant Director General for Communicable and Noncommunicable Diseases Jerome Salomon,  underscored the establishment of a joint working group to eliminate hepatitis C.

The officials met on the sidelines of the 77th World Health Assembly (WHA) held in Geneva, Switzerland, from May 27 to June 1.

During the meeting, Farshidi presented a report on the measures taken in Iran to control and prevent hepatitis C and stressed the key strengths of Iran's national program, including the strong primary health care services (PHC) and the integration of the programs to fight and manage hepatitis.

Salomon, for his part, lauded Iran for its commitment and strong will in the elimination of hepatitis C and announced WHO’s readiness to support Iran's plans in this area.

He also called Iran a role model for other regional countries in the elimination and control of hepatitis C.

Iranian Researchers Offer Innovative Way to Desalinate Sea Water for Remote Areas

Researchers at the Faculty of Mechanical Engineering, University of Tehran have designed and offered an innovative environmentally-friendly system for supplying freshwater from the sea water to remote areas.

Ehsan Hooshfar, an Associate Professor of Energy Conversion at the University of Tehran (UT), was the executive director of the project to desalinate sea water and supply drinking water to remote areas.

“In this research, a new solution for desalination of sea water has been proposed, which is called Humidification-dehumidification or HDH for short, and is inspired by the process of rain production. In fact, the use of desalination systems for desalination of sea water, which is one of the conventional ways of supplying fresh water, is done in many ways each of which comes with pros and cons,” Hooshfar said.

“The advantage of the method introduced in this research is less energy consumption than other methods. It uses the waste heat produced by other systems,” the UT researcher said, adding, “In this research, an independent desalination unit using HDH, solar panels for simultaneous production of electricity and heat or hotovoltaic/thermal (PVT) solar hybrid system and compression chiller is proposed to provide stable water to remote areas that have access to sea water. The system operates in a way that is that the solar panel provides the electricity required for the chiller and the heat required for the HDH, and the incoming seawater is preheated by the condenser of the chiller. This way, the overall performance of the system in fresh water production is significantly improved.”

“Modeling of this system was done by using an artificial neural network trained for tri-objective optimization by employing a genetic algorithm. The goals of this optimization included maximizing fresh water production, minimizing costs, and maximizing system efficiency,” Hooshfar added.

“The results showed that this system is technically and economically competitive in producing fresh water with other desalination units for remote areas. Also, due to the correct choice of refrigerant and the use of renewable energy, it is environmentally friendly,” the UT professor added.

Iranian Knowledge-Based Firm Produces Shrimp Larvae Counting Machine

Experts at a knowledge-based company based in the Science and Technology Park of Markazi Province in Iran have managed to design and produce a shrimp larva counting machine using locally developed know-how and technology.

“Our product, the shrimp larva counting machine, is considered as one of the important needs of the fisheries industry. This product had been requested by the shrimp farmers to the fisheries organization for years,” said Farzin Nadi, the Managing Director of Pishtaz Pardezesh Saray Jonoub Rooz, knowledge-based company told ANA in an interview.

“Due to the challenges and complexities of this device as well as the high prices of its foreign-made counterparts, its domestic model was designed and produced by our company's experts,” he added.

He added that because in the fishery market, buying and selling shrimp larvae is done through counting the number of larvae, therefore counting the larvae is of great importance.

Nadi also said that knowing the number of available aquatics is one of the most important information that a shrimp and aquatic animals breeder should have access to, because it is based on that the amount of feeding, control of water parameters, payment of purchase and sale fees is determined.

Irrigation Hardware, Software System Unveiled on Last Day of AbadIran Exhibition

A hardware and software system for irrigation , which has been designed and produced by one of the knowledge-based companies in Iran, was unveiled on the last day of the AbadIran exhibition in the Northern part of the capital city of Tehran.

During a ceremony on the last day of the second edition of AbadIran exhibition, held on June 11-14 at Tehran's Mossalla (Grand Mosque) which was attended by a number of Iranian officials, Ryan Arvin Algorithm knowledge-based company unveiled its hardware and software tools for irrigation.

“This product is a special hardware and software system for irrigation on farms. It does a systematic integration for farmers and they can see all the fields in one panel,” Mohammad Javad Motahari Sharif, the founder of the knowledge base company said about their product.

Pointing out that the system notifies the farmer of the best watering time and the exact amount of water to the plants, he added, “This will reduce the water consumption rate and water stress of the plant.”

“Also, this system optimizes fertilizer use, meaning that usually during fertilizing, due to high water consumption, the fertilizer leaves the root area, but with this system 40% less water consumption happens therefore the fertilizer could be used optimally. Moreover, with prevention of water stress, the crops performance and quality would enhance,” Motahari Sharif explained.

Iranian Researchers Design, Produce New Nano Insulator to Assist Under-Developed Areas

Researchers at one of the companies located in the Science and Technology Park of Markazi Province have designed and produced reasonably-priced nano insulators that can replace bituminous waterproofing.

“Nano insulators are a suitable substitute for bituminous waterproofing. These insulators last for a long time and are very easy to use. They do not need a flame or any special conductor and are highly resistant against humidity. Ordinary people, even women, can use it simply and without any expertise by studying the manual of the products. Our product, which has a long shelf life, is also resistant against the sunlight and reasonably priced,” said Ali Jamshidi, the managing director of the company.

“This insulator is milky in color and becomes colorless after use. It can also be used to build swimming pools, fountains, ponds, roofs, toilets, building facades, stone, brick, mosaic, straw, plaster, cement, wood and fabric,” he added.

“Currently, the country's low-income people cannot afford expensive insulators. One liter of this product is available for sale in the market at the price of 60,000 to 70,000 Tomans,” the researcher said, adding, “The price of this product is almost one euro per liter which in comparison with the imported materials, is almost six euros cheaper." 

“Currently, by exporting this product to countries like Iraq and Armenia, we have been able to generate good amount of revenues for the country. This year, we were able to sell as much as five billion Tomans of these products to foreign markets,” Jamshidi added.

“We intend to increase our production line and the amount of production of equipment as well as exports,” the managing director of the company concluded.

Iranian Company Indigenizes 3-Phase 500-MVA Supertransformer

The Iranian experts at a knowledge-based company succeeded in manufacturing a three-phase integrated 500MVA (Megavolt Ampere) supertransformer for the country’s power grid.

“This giant supertransformer is about 14 meters long, 9 meters wide, and 10 meters high, and weighs over 335 tons, and it replaces three single-phase transformers which saves about 60% of the space required for placing transformers in the substation and prevents 70% of network no-load losses,” said Mehdi Sadeqi, the managing director of the knowledge-based company.

He added that the knowledge-based product will also reduce post construction costs and facilitate the operation and monitoring process.

Sadeqi underlined that construction of the transformer started in the presence of the Iranian Energy Minister during the 23rd International Electricity Industry Exhibition in Tehran last year.

“Despite the significant complications in calculations and design of this supertransformer, we reached the testing and unveiling state within six months,” he noted.

Iranian Researchers Recycle Wastewater for Fish Farming, Poultry Breeding, Greenhouse Products

The water recycling system and the use of wastewater in the three fields of fish breeding, greenhouse products and poultry breeding is the achievement of one of the knowledge-based companies.

At present, the company produces 12 tons of fish, 20 tons of tomatoes, 3 tons of quail meat, and 9 tons of quail eggs with a 95% reduction in annual water consumption.

By recirculating water and reusing the effluents of the three areas of fish breeding, greenhouse products and poultry, the problems of all three areas like mechanical equipment, food supplements and reinforcing fertilizers are settled.

In this project, the amount of consumed water is reduced by 95%, but the amount of fish production will be equal to similar ponds. In this method, the pool water will return to the hydroponic greenhouse culture bed, and the cost of greenhouse production will be reduced by a third before operation and during operation.

In this cycle, water is oxygenated, and since chemical fertilizers cannot be used to grow plants, they use animal manure and quail excrement. In fact, animal excrement supplies the level of chemical deficiencies of water, and the excrement solution is regulated based on the nutrition of quails.
