The Potential of Microbial Mediated Fermentation Products of Herbal Material in Anti-Aging Cosmetics
Namrita Lall in Medicinal Plants for Cosmetics, Health and Diseases, 2022
Biotransformation of phytochemicals as a result of fermentation may result in various changes to the structure and function of these compounds. For example, this biotransformation may cause the conversion of an active compound to a less active metabolite, also referred to as inactivation or detoxification. 1,1,1-Trichloro-2,2-bis (p-chlorophenyl) ethane (DDT) has been used for the control of agricultural pests, and for protection against malaria and typhus. Due to its adverse environmental effects and potential risks to human health, it was subsequently banned in many parts of the world. DDT and its metabolites persist in soils for extended periods, and this is exasperated by the continued use of dicofol. Physical and chemical remediation offer disadvantages including that they are costly an often result in secondary pollution. Microbial mediated remediation offers a more economic and safer alternative as a few strains have been shown to utilize DDT as a carbon source, including Alcaligenes eutrophus A5, Alcaligenes sp. KK, Alcaligenes sp. DG-5, Chryseobacterium sp. PYR2, Rhodococcus sp. IITR03 Aeromonas hydrophila HS01, Pseudomonas putida T5, Pseudomonas aeruginosa, Flavimonas oryzihabitans and Sphingobacterium sp. D-6 (Barragán-Huerta et al., 2007; Hsu and Chiang, 2009; Gao et al., 2011; Xie et al., 2011; Cao et al., 2012; Rangachary et al., 2012; Bajaj et al., 2014; Qu et al., 2015; Erdem and Cutright, 2016).
Developmental disorders, Part 4: Motor development 1
Quentin Spender, Judith Barnsley, Alison Davies, Jenny Murphy in Primary Child and Adolescent Mental Health, 2018
Paediatric occupational therapists may be able to provide direct remedial treatment on a group or individual basis, in school or in a health setting; or indirectly via school staff. As well as improving skills, they are concerned with maintaining any skills the child may have. Group interventions (in either school or clinic) may take a sensori-motor approach, which means improving sensory processing in order to develop motor skills. Remediation may focus on: muscle strengthbody posture (often crouched and awkward)body image (usually distorted)sensory issuesfine motor dysfunction, including for instance: pencil griptying shoe laceseating properly. Improving skills in these areas may provide the child with a much-needed boost to his self-esteem.
Radioactive waste and the decommissioning of radioactive facilities
Alan Martin, Sam Harbison, Karen Beach, Peter Cole in An Introduction to Radiation Protection, 2018
At the end of decommissioning, it is important to decide whether the land on which the nuclear facility was sited can be released. Even after the plant and structures have been removed, there is always the possibility that low levels of radioactivity will remain on or under the surface of the site. Before such a site can be released for other use, it is necessary to go through a formal monitoring and clearance process. The monitoring involves a detailed programme of both direct radiation monitoring and soil sampling for laboratory analysis. When significant levels of site contamination are detected, a programme of site remediation must be undertaken. This might entail the excavation of areas of the site and removal of the soil to a suitable approved landfill site. In other cases, depending on the levels and extent of the contamination, the radionuclides present and the planned use of the site, it may be acceptable to bury the contaminated soil directly on the site, ensuring that there is an adequate thickness of cover. The criteria for clearance of sites vary to some extent from country to country. For clearance of nuclear sites in the United Kingdom, the regulatory authority considers that any residual radioactivity above the natural background that can be demonstrated to pose a risk to any person of less than one in a million per year would be broadly acceptable. This corresponds to an average radiation dose rate above that from natural background of about 20 μSv/y.
Twelve tips for providing academic remediation to widening access learners in medical education
Published in Medical Teacher, 2023
Ashley Selva-Rodriguez, John Sandars
Adopting a holistic approach to remediation requires using several theoretical lenses that account for the inherent complexity of the remediation process. A holistic approach is underpinned by humanistic psychology theory that emphasizes looking at the whole person and the ecological theory that accounts for the academic macrosystems and microsystems that impact a learner’s experience (Bronfenbrenner and Evans 2000). With this overarching framework at the center of the remediation process, providers of academic support staff can identify concerns and situate them within the interrelated dimensions that can impact success: intrapersonal (cognitive, motivational and affective), interpersonal (relationship with peers and faculty) and structural (medical school systems and societal influences, such as financial support) (Sandars et al. 2014). For example, providers of academic support may discover that in addition to difficulties with time management the learner has anxiety and would benefit from a referral to a counselor.
Differences between high- and low-achieving pre-clinical medical students: a qualitative instrumental case study from a theory of action perspective

More specifically, this study proposes governing variable-based remediation. Per Figure 3, this remediation is intended to guide low-achieving students to shift from a Negative Enabling Pathway to a Positive Enabling Pathway. It is imperative that the Negative Enabling Pathway be identified and eliminated. By replacing negative governing variables with positive governing variables, students will be empowered to act proactively and identify positive actions to achieve an intended outcome. Indeed, the appropriate learning approach has been shown to require less effort and lead to better results [24,25], making the proposed remediation more effective. For instance, if possessing positive governing variables, students will actively seek remediation, rather than passively waiting for remediation to be offered. This observation corresponds with the findings of Yip et al. [39] that developing a self-motivated attitude is essential for academic success.
An investigation of instructional practices which promote occupational safety and health

The modern workplace favors those with transferable skills that are provided in CTE [24]. Since CTE programs are a training ground for the workforce, CTE educators have a major responsibility to utilize instructional practices that promote proper safety and health skill development in students. Our analysis of the results from the first research question suggests that safety is a critical component in the CTE curriculum for a majority of the participants in this study. This is a positive finding, and the instructors should be commended for their efforts to consistently teach OSH during the academic year. However, there are some areas that require remediation. The instructors indicated that very little OSH training is dedicated to hearing protection. This limited training on hearing protection means that students may develop improper safety and health practices. The students may well transfer these practices to their careers.
