Due to the Green Deal's strictures, the circular economy has become a crucial issue within the European Union. The purpose of the study is to determine the most efficient functioning of CEs at the macro level by the selection of the most suitable potential requirements for small and medium businesses, as an extension of a voluntary environmental management toolu2014ISO 14001. According to the widely conducted Delphi report, the main conclusion is that a more circular management framework is both feasible and required in SME companies.

Over the past few years, demand for Liquefied natural gas has skyrocketed. LNG is one of the clean energy sources that has attracted a lot of attention. The fatigue damage factor for all of the test cases was much lower than 1. The maximum principal strain in the 40 ft LNG ISO tank container exceeded the calculated value, despite the calculated yield strength. With low-cycle and high-cycle analysis, respectively, a maximum principal stress of 123. 2 MPa and 107. 61 MPa was obtained, which is 50. 8 percent less than carbon steel's yield strength. The total number of cycles was greater than the total number of design cycles, and the 40 ft LNG ISO tank container was used with a fatigue life of 20 years, and the total number of cycles was more than doubled over.

Sharka disease, caused by the Plum pox virus, is one of the most infectious, quarantine viral diseases that affect stone fruit crops. Natural resistance to the virus in stone fruits has been a determining factor in the use of genetic transformation techniques to obtain stable forms. The eIF4G and eIF4E genes encode translation initiation factors used in the PPV life cycle. The vulnerability of sour cherry rootstock 146-2 plants to the sharka disease was investigated in the present study. Plants that cannot be found intragenic marker-free plants were produced using the pMF1 vector containing recombinase R and a codA-nptII gene. The AGL0 strain of A. tumefaciens is responsible for a successful genetic transformation. The quantitative PCR revealed that quantitative PCR had confirmed the silencing of the eIF4G and eIF4E genes in transgenic plants. PPV plants of all transgenic rootstock lines were infected with PPV by the process of grafting with infected buds. After infecting, two years after infecting, the ELISA findings revealed that silencing the eIF4G gene did not result in increased resistance, but silencing the eIF4G gene resulted in increased resistance to the PPV. The study shows how a mosaic technique can be used to produce stone cultures resistant to the plum pox virus by suppressing the genes of translation initiation factors in clonal rootstocks.

The minimum dimension of a gamma radiation reference field in the most recent version of ISO 4037-1:2019 is not clearly specified, causing the construction of a minitype gamma reference radiation field lacking scientific credibility. This paper reported on the relationship between the scattering contribution and physical characteristics of the reference radiation tightly controlled by ISO 4037-1. By PSO's algorithm, the minimum dimension of collimated reference radiation field can be determined. The minimum size of the radiation field obtained by Cs-137 is 153 cm. /u00d747 cm.

Risk assessment and the areas that will be the focus of risk management are two of the areas that will be the subject of risk management's attention. The stages of the investigation process that are by design method include gathering the risks faced by the company, determining the risk profile, and using a risk matrix for risk management priority exposure. The findings of the risk management investigation revealed in the form of the basic rules of implementing risk management with the ISO 31000 standard, which is a suggestion to the organization in assessing risk by using applicable standards.

This gives data librarians an opportunity to assist with formatting dates, but there are frequent examples of data librarians using diverse tactics for this purpose. Data librarians must adopt ISO 8601 and push for its use as a data management best practice as regular advocates for standardization in research results.

The present paper seeks to determine the effect of Food System Management ISO 22000 on Coca-Cola's loyalty in Algeria by satisfaction as an intermediate variable. The findings also showed a poor indirect correlation between food safety management techniques and customer loyalty, as shown by a correlation coefficient, which was estimated at 0. 23 percent. In fact, the implementation of a food safety management system contributes directly to customer satisfaction and even loyalty.

The minimum dimension of a gamma radiation reference field in the new ISO 4037:2019 version was not clearly stated, which makes the design of a minitype gamma reference radiation field lacking scientific credibility. Based on the Monte Carlo simulation results, LS-SVM was used to build the relational model based on the Monte Carlo method's simulations. By the PSO algorithm, the minimum dimension of collimated reference radiation field can be obtained. The minimum size of the radiation field obtained for Cs-137 is 153 cm/u00d747 cm u00d747 cm.
Solid oxide fuel cells directly fed with iso-octane are expected to be power sources for cellphones and automobiles. The anode includes a Ni-CeO2 catalyst layer as the top layer, an Ni catalyst layer as the second layer, and a Ni-YSZ catalyst layer as the third layer on top of the electrolyte. The three-layer anode's idea is as follows: fuel reforming occurs in the Ni-CeO2 layer, the newly formed H2 or CO layer is electrochemically oxidized in the Ni-YSZ catalyst layer, and the Ni catalyst middle layer prevents the reaction between YSZ and CeO2:.
