The Impact

The impact of mixing on the promotion of microorganism growth rate has been analyzed using a multiphase forced-circulation pipe-loop reactor model capable of identifying conditions under which it is possible to convert natural gas into Single-Cell Protein. The impact of mixing in the interphase mass transfer was found to exert a critical role in determining the overall productivity of the bioreactor, particularly at the high cell loadings needed to reduce the capital costs associated with the large-scale production needed for the production of relatively low-value SCP in a sustainable manner.

Whilst agricultural research world-wide pursues yield improvement in food and forage crops in an attempt to keep pace with growing demand, alternative ‘non-crop’ protein sources have also been sought. Bacteria and yeasts have been shown to have the characteristics necessary for large-scale production of what has come to be known as single-cell protein. ICI's ‘Pruteen’, using a unique continuous fermentation system, compares favourably with conventional protein feedstuffs.

Archival Processing

Introduction Few writings within the realms of archives and special collections have reverberated throughout the field to the degree of Mark A. Greene and Dennis Meissner’s 2005 article “More Product, Less Process: Revamping Traditional Archival Processing.”1 Its clarion call to shift archival arrangement and description away from time-consuming, detailed processes toward rapid, minimalist strategies was met with both cheers and groans that continue unabated. In a sign of its ubiquity, the approach advocated by Greene and Meissner is now simply referred to as “MPLP,” and its implementation is the subject of ongoing discussion in numerous venues, including professional journals, conference . . .

The Impact

The SARS-CoV-2 pandemic has brought about the unprecedented expansion of highly sensitive molecular diagnostics as a primary infection control strategy. At the same time, many laboratories have shifted focus to SARS-CoV-2 research and diagnostic development, leading to large-scale production of nucleic acids that can interfere with these tests. We have identified multiple instances, in independent laboratories, in which nucleic acids generated in research settings are suspected to have caused researchers to test positive for SARS-CoV-2 in surveillance testing. In some cases, the affected individuals did not work directly with these nucleic acids, but were exposed via a contaminated surface or object. Though researchers have long been vigilant of DNA contaminants, the transfer of these contaminants in SARS-CoV-2 testing samples results in anomalous test results. The impact of these stretches into the public sphere, placing additional burdens on public health resources, placing affected researchers and their contacts in quarantine, and carrying the potential to trigger shutdowns of classrooms and workplaces. We report our observations as a call for increased stewardship over nucleic acids with the potential to impact both use and development of diagnostics. These experiences highlight a neglected aspect of the test, trace, isolate public health strategy for managing COVID-19: we cannot easily identify and diagnose an erroneous test result. To prevent undue personal and economic strain and maintain faith in the testing process, we propose: a test, isolate, verify, and trace approach to COVID-19 diagnosis in research and clinical diagnostic workplaces.

The study evaluated the impact of fermentation with Bacillus sp. on the nutritional quality of soybean meal (SBM) and the changes of bacterial community structure during fermentation. High protease-producing strains were screened to degrade SBM macromolecular protein and anti-nutritional factors (ANFs). Unsterilized SBM then underwent an anaerobic solid-state fermentation method to evaluate the effects of fermentation. Results showed that for the nine high-producing protease strains that were screened, acid-soluble protein (ASP) contents in fermented SBM increased, with the highest value found to be 13.48%, which was fermented using strain N-11. N-11 was identified as Bacillus subtilis. N-11 fermentation reduced ANFs such as glycinin and β-conglycinin by 82.38 and 88.32%, respectively. During N-11 fermentation, the bacterial richness and diversity in SBM increased but not significantly. The high-yield protease strain B. subtilis N-11 selected in this experiment improved the nutritional quality of SBM through fermentation, and it can be used for industrial large-scale production.

Diabetes Mellitus is one of the World Health Organization's priority diseases under research by the first and second programmes of Innovative Medicines Initiative, with the acronyms IMI1 and IMI2, respectively. Up to October of 2019, 13 projects were funded by IMI for Diabetes & Metabolic disorders, namely SUMMIT, IMIDIA, DIRECT, StemBANCC, EMIF, EBiSC, INNODIA, RHAPSODY, BEAT-DKD, LITMUS, Hypo-RESOLVE, IM2PACT, and CARDIATEAM. In general, a total of €447 249 438 was spent by IMI in the area of Diabetes. In order to prompt a better integration of achievements between the different projects, we perform a literature review and used three data sources, namely the official project's websites, the contact with the project's coordinators and co-coordinator, and the CORDIS database. From the 662 citations identified, 185 were included. The data collected were integrated into the objectives proposed for the four IMI2 program research axes: (1) target and biomarker identification, (2) innovative clinical trials paradigms, (3) innovative medicines, and (4) patient-tailored adherence programmes. The IMI funded projects identified new biomarkers, medical and research tools, determinants of inter-individual variability, relevant pathways, clinical trial designs, clinical endpoints, therapeutic targets and concepts, pharmacologic agents, large-scale production strategies, and patient-centered predictive models for diabetes and its complications. Taking into account the scientific data produced, we provided a joint vision with strategies for integrating personalized medicine into healthcare practice. The major limitations of this article were the large gap of data in the libraries on the official project websites and even the Cordis database was not complete and up to date.

The Impact

We have had high expectations for using algae biodiesel for many years, but the quantities of biodiesel currently produced from algae are tiny compared to the quantities of conventional diesel oil. Furthermore, no comprehensive analysis of the impact of all factors on the market production of algal biodiesel has been made so far. This paper aims to analyze the strengths, weaknesses, opportunities, and threats associated with algal biodiesel, to evaluate its production prospects for the biofuels market. The results of the analysis show that it is possible to increase the efficiency of algae biomass production further. However, because the production of this biodiesel is an energy-intensive process, the price of biodiesel is high. Opportunities for more economical production of algal biodiesel are seen in integration with other processes, such as wastewater treatment, but this does not ensure large-scale production. The impact of state policies and laws is significant in the future of algal biodiesel production. With increasingly stringent environmental requirements, electric cars are a significant threat to biodiesel production. By considering all the influencing factors, it is not expected that algal biodiesel will gain an essential place in the fuel market.

Abstract In engineering industry the production of components begins with separation of the base material and this technological operation can be time consuming, especially in large-scale production. Such production can be made more efficient by means of laser technology focusing on material cutting. Efficiency of cutting is determined not only by shortening of working time or energy saving, but also by the required cutting quality. In the paper we compare the impact of cutting speed changing and laser beam performance on the cutting edge quality. Based on requirements of dimensional accuracy and preset roughness of the cutting edge, we evaluated the cutting quality of laser in samples of different materials. Measured values of sample dimensions and roughness are compared in conclusions of the paper, where we estimate whether the samples meet specified requirements of dimensional accuracy and roughness of the cutting edge in order to make the production process more efficient.

The literature on female labour in Third World countries has become quite extensive. India, being comparatively more advanced industrially, and in view of its size and population, presents a pictures of multiplicity of problems which face the female labour market. However, the author has also included Mexico in this analytical study. It is interesting to see the characteristics of developing industrialisation in two different societies: the Indian society, which is conservative, and the Mexican society, which is progressive. In the first chapter of the book, the author explains that he is not concerned with the process of industrialisation and female labour employed at different levels of work, but that he is interested in forms of production and women's employment in large-scale production, petty commodity production, marginal small production, and self-employment in the informal sector. It is only by analysis of these forms that the picture of females having a lower status is understood in its social and political setting.
