Today, in the energy sector, a promising direction for the use of renewable energy sources. A variety of enterprises often have production waste that can be used as renewable secondary energy resources. The concept of lean manufacturing goes hand in hand with increased environmental sustainability. Reducing production waste to a minimum by recycling it increases the energy-saving potential of production, on the one hand, and the indicator of environmental safety, on the other. Currently, the problem of utilization and further use of animal manure is relevant. One of the options for efficient processing of manure and obtaining valuable products from it is the production of biogas. Biogas technologies make it possible to most rationally convert the energy of chemical bonds of organic waste into the energy of gaseous fuel. Therefore, the search for new technologies for producing biogas is relevant in our time. Attention is paid to the processes of co-fermentation of animal waste with vegetable raw materials, the effects of increasing the yield of biogas are indicated.

Robotic co-workers are an emerging generation of physical robots promises to transform manufacturing with its ability to communicate and collaborate, both robot-to-robot and robot-to-human, opening the way to greater innovation and productivity. We designed a welding robotic co-worker which observes industrial part, searches welding seams, plans welding trajectory, and simulates welding result automatically. It largely benefits small and medium-sized manufacturing enterprises (SMEs) by allowing manufacturers handle low-volume orders without re-programming. As a co-worker, the robot communicates with its operator though brain computer interface (BCI) as well as guarantees the operator’s safety. We demonstrated the performance of this robot using a human subject study in welding simulation environment.

The sealing of moving parts under high pressure is one of the most demanding tasks in high pressure technology. For the design of the sealing elements all influencing factors such as mechanical deflections, motion speeds and fluid properties under high pressure must be fully understood and considered. Developments in both materials and manufacturing methods provide new possibilities for the design of sealing systems. This technical paper describes typical sealing issues of dynamic seals at pressures in excess of 35 kpsi with emphasis on plunger seals of high pressure reciprocating pumps. Different plunger sealing concepts are compared and their technical characteristics are analyzed. A new friction-free metallic sealing system is presented and the performance of the sealing system is illustrated by means of numerical simulations considering the fluid-structure interaction and operational experience. The paper further summarizes investigations carried out on changes of fluid properties due to high pressure and shows how this influences the sealing system and the performance of high pressure pumps. Based on this data recommendations are given to prevent problems due to crystallization or polymerization which typically arises in high pressure co-monomer feed systems. The progress in sealing technology reveals new perspectives for high pressure applications in LDPE production plants.

Abstract Solid oxide fuel cells (SOFCs) are typically operated in a dual-chamber setup, where the fuel and oxidant flows are separated by the fuel cell. However, dual-chamber SOFCs (DCSOFCs) require sealant to keep the flows separate, meaning that rapid heating and cooling cycling could break the seal. The initial answer to this problem was a single-chamber SOFC (SC-SOFC). The SC-SOFC is simply a planar fuel cell mounted parallel to a mixed fuel and oxidant flow. This system operates through the catalytic reactions of the anode and cathode with the fuel and oxidant, respectively. The drawback of this design comes from the requirement of fuel rich flow. A fuel lean flow leads to the oxidation of the anode and failure of the cell. On the other end, a fuel rich flow will greatly decrease system efficiency as much fuel will pass the cell and be wasted, making SC-SOFCs a difficult technology to implement. This issue led to the development of a porous SOFC (PSOFC), as a variant on the SC-SOFC. The PSOFC incorporates a similar mixed flow but is mounted perpendicular to the flow with cathode upstream of anode, and a catalyst downstream of the anode with the goal of reforming exhaust into syngas for a zero-emission fuel cell. Pores through the entire cell allow the flow to reach the anode, from the cathode side of the cell. The zero-emission condition is realized with the use of hydrocarbon fuels in the mixed flow. Reactions of fuel and air in the cell result in products of CO2 and H2O, which are then reformed by the catalyst into syngas (H2 and CO). Exhaust reformation by the catalyst is possible due to the high operating temperature of SOFCs. Syngas from the cell may be used immediately for further electricity generation or stored for later use. Manufacturing of a PSOFC is carried out with additive manufacturing (3D printing). Techniques of manufacturing PSOFCs will be discussed. The catalyst layer has been omitted from cell production until electricity generation performance of the cell improves. PSOFCs tested thus far have produced under 100 mW/cm2 with an open circuit voltage (OCV) of 0.60 V. This performance is not enough to begin implementing PSOFCs in industry. However, it does set a solid base for future PSOFCs and shows that they are a viable source of power generation. With further improvement of manufacturing methods and implementation of a catalyst, PSOFCs will become an important tool in zero-emission power production.

Abstract Driven by the search for an optimum combination of particle velocity and process temperature to achieve dense hard metal coatings at high deposition efficiencies and powder feed rates, the high velocity air-fuel spraying process (HVAF) was developed. In terms of achievable particle velocities and temperatures, this process can be classified between high velocity oxy-fuel spraying (HVOF) and cold gas spraying (CGS). The particular advantages of HVAF regarding moderate process temperatures, high particle velocities as well as high productivity and efficiency suggest that the application of HVAF should be also investigated for the manufacture of MCrAlY (M = Co and/or Ni) bond coats (BCs) in thermal barrier coating (TBC) systems. In this work, corresponding HVAF spray parameters were developed based on detailed process analyses. Different diagnostics were carried out to characterize the working gas jet and the particles in flight. The coatings were investigated with respect to their microstructure, surface roughness and oxygen content. The spray process was assessed for its effectiveness. Process diagnostics as well as calculations of the gas flow in the jet and the particle acceleration and heating were applied to explain the governing mechanisms on the coating characteristics. The results show that HVAF is a promising alternative manufacturing process.

<div class="section abstract"><div class="htmlview paragraph">The search for a new renewable biofuel and aiming to make the environment clean is always a challenge for a researcher in developing a sustainable fuel for future mobility. In this context, vegetable oils were found as good alternative biofuels for diesel engines as they are biodegradable and renewable in nature. Most of the physio-chemical properties of vegetable oils are very closer to diesel. However, pure vegetable oils are expensive and using them to operate the diesel engine may affect the food supply chain. In view of this limitation, Waste Cooking Oil Biodiesel (WCOB) derived from waste cooking oil (WCO) was found to be very attractive solution for the above said constraints as they are easily available, renewable, economically and environmentally viable. This research aims at studying the effect of hybrid nano additives (i.e. Copper Oxide with Zinc Oxide) on performance and emission characteristics of a diesel engine fueled with Waste Cooking Oil Biodiesel. The Copper oxide with Zinc oxide hybrid nano fluids were prepared by a novel wet chemical method. These nano fluids were prepared in two mass fractions (i.e. 50ppm and 100ppm) and blended with WCOB and considered as test fuels such as WCOBCZ50 and WCOBCZ100. The stability of hybrid nano fluids prepared by wet chemical method and blended with WCOB was found good. The fuels diesel, WCOB, WCOBCZ50 and WCOBCZ100 were tested in the test engine at different loading conditions to evaluate the engine performance and emission parameters. The experimental results revealed that the addition of hybrid nano additives in WCOB improved the fuel properties which were reflected in terms of increased brake thermal efficiency and reduced brake specific fuel consumption compared to neat WCOB. It was also observed that HC, CO, NOx and smoke emissions were reduced with the addition of hybrid nano additives as compared to neat WCOB. Thus, it can be concluded that inclusion of hybrid nano additives pave way for effective utilization of WCOB in an unmodified diesel engine over a period of time.</div></div>

Kashiwazaki-Kariwa Nuclear Power Station Unit 6 and Unit 7 (K6 & K7) are the first advanced boiling water reactors (ABWR) in the world. Toshiba has been engaged in the design and construction of boiling water reactors (BWR) for Hamaoka Nuclear Power Station Unit 5 (H5) of Chubu Electric Power Co., Inc. and Higashidori Nuclear Power Station Unit 1 of Tohoku Electric Power Co., Inc. H5 has features of the simplified reactor coolant recirculation system including a reactor internal pump (RIP) and reduction in plant startup time using a fine-motion control rod drive (FMCRD). The H5 has been improved through additional modifications such as a reduction in the number of adjustable speed drives (ASDs) required by RIPs. This was managed through multi drive and the elimination of a shaft seal from FMCRDs by applying magnetic coupling. The basic performance of the modified FMCRD (S-FMCRD) has been verified by the joint study of Japanese operating utilities and vendors. In addition, various other tests are performed on the H5 to validate its actual component design during the manufacturing stage and pre-operation stage. Construction of H5 began in March 1999. Bedrock inspection was completed in May 2000, the reactor pressure vessel (RPV) installation was finished in July 2002, and power receiving was completed in December 2002. Currently, H5 is scheduled to start commercial operation in January 2005. Pre-operating tests began at the end of 2002. The utility systems test, like the MUWP (makeup water system), HVAC (heating, ventilation and air conditioning), etc, began two months prior to power-receiving, followed by both the RCCW (reactor building closed cooling water system) and RCWS (reactor building cooling sea water system) tests. The primary system pre-operating test, which is usually performed at the peak of the pre-operating test period, was completed by mid-February, 2004. Each test schedule was controlled and each test followed the predefined test plan. On the other hand, S-FMCRDs and control rods (CRs) were installed, followed by an RPV overpressure integrity inspection test conducted in September 2003. Following this test, RIPs and related control system confirmation tests was performed Subsequently, FMCRDs pre-operation test was planned to confirm performance levels. The modified design concepts, such as S-FMCRDs and multi drive ASDs for RIPs etc, were scheduled for verification during this phase.

"Diagnosing infections with SARS-CoV-2 is still of great interest due to the health and economic impact of COVID pandemic. The 4th wave of the COVID-19 pandemic is expected and is considered to be stronger and faster due to the dominance of Delta variant which is highly contagious [1]. SARS-CoV-2 also known as 2019-nCoV is one of the three coronaviruses (together with SARS-CoV or SARS-CoV1/Severe acute respiratory syndrome coronavirus), MERS-CoV /Middle East Respiratory Syndrome coronavirus) which can cause severe respiratory tract infections in humans [2]. Early diagnosis in COVID 19 infection is the key for preventing infection transmission in collectivity and proper medical care for the ill patients. Gold standard for diagnosing SARS-Co-V-2 infection according to WHO recommendation is using nucleic acid amplification tests (NAAT)/ reverse transcription polymerase chain reaction (RT-PCR). The search is on to develop reliable but less expensive and faster diagnostic tests that detect antigens specific for SARS-CoV-2 infection. Antigen-detection diagnostic tests are designed to directly detect SARSCoV-2 proteins produced by replicating virus in respiratory secretions so-called rapid diagnostic tests, or RDTs. The diagnostic development landscape is dynamic, with nearly a hundred companies developing or manufacturing rapid tests for SARS-CoV-2 antigen detection [3]. In the last 3 months our hospital introduced the antigen test or Rapid diagnostic tests (RDT) which detects the presence of viral proteins (antigens) expressed by the COVID-19 virus in a sample from the respiratory tract of a person. All RDT were confirmed next day with a RT-PCR. The number of positive cases detected during 3 months in our laboratory was 425. There were 326 positive tests in April, 106 positive tests in May and 7 positive tests in June. Compared with the number of positive tests in the 1st semester of 2021, the positive tests have significantly declined."
