Pilot Study to Improve Nanofluid Heat Transfer Characteristics SciReports carbonnanotubes nanomaterials nanoanalysis
By Hussain AhmedSep 10 2022Reviewed by Megan Craig, M.Sc. Nanofluid is regarded as the heat transfer fluid of the future in a variety of heat transfer applications. A nanofluid provides higher thermal performance than normal fluids due to dispersed nanoparticles with high thermal conductance.
A nanofluid can greatly improve heat transmission and thermophysical properties such as viscoelasticity, flash point, heat capacity, and cooling rate. Metals, metallic oxides, and carbon-based nanostructures are some of the nano additives utilized in creating nanofluids. MWCNTs can considerably improve the thermophysical characteristics of a nanofluid because MWCNTs have about five times the thermal conductance of other common materials. As a result, MWCNTs nanofluid's increased thermal conductivity provides a better heat transfer efficiency in the applied systems.
Until now, most studies on cooling systems have concentrated on enhancing cooling tower effectiveness by taking into account various factors such as environmental scenarios, physical elements, and operational parameters. Nevertheless, the impact of employing nanoparticles, such as TiO2 nanoparticles, on producing a system's working fluid is not entirely understood.
During the investigation, the efficiency, Merkel numbers, and cooling range of MWCNTs and TiO2 nanofluids were also examined. In addition, the optimal and economic optimization for different parameters were shown. The researchers' earlier halfway investigation on the impacts of employing MWCNT nanofluid was resumed and finished in this research. Prior findings were analyzed with the contemporary data of TiO2 nanofluid.

What you don’t know can still hurt you - underreporting in EU pesticide regulation - Environmental HealthThe safety evaluation of pesticides in the European Union (EU) relies to a large extent on toxicity studies commissioned and funded by the industry. The herbicide glyphosate and four of its salts are currently under evaluation for renewed market approval in the EU. The safety documentation submitted by the applicant companies does not include any animal study regarding developmental neurotoxicity (DNT) that is compliant with test guidelines. For a fifth salt, not included in the present application for re-approval, such a DNT study was sponsored by one of the applicant companies in 2001. That study shows an effect of that form of glyphosate on a neurobehavioural function, motor activity, in rat offspring at a dose previously not known to cause adverse effects. Counter to regulatory requirements, these effects were apparently not communicated to authorities in EU countries where that form of glyphosate was authorised at that time. That DNT study may also be relevant for the ongoing assessment of glyphosate but was not included in the present or previous applications for re-approval.In this commentary, we highlight that it is the responsibility of the industry to evaluate and ensure the safety of their products, taking all available scientific knowledge into account. We argue that the legal obligation for industry to submit all potentially relevant data to EU authorities is clear and far-reaching, but that these obligations were not fulfilled in this case. We claim that authorities cannot reliably pursue a high level of protection of human health, if potentially relevant evidence is withheld from them. We suggest that a retrospective cross-check of lists of studies performed by test laboratories against studies submitted to regulatory authorities should be performed, in order to investigate the completeness of data submitted to authorities. We further suggest that future toxicity studies should be commissioned by authorities rather than by companies, to improve the au

Bullying at 8 years and violent offenses by 31 years: the Finnish nationwide 1981 birth cohort study - European Child & Adolescent PsychiatryThis study explored the associations between bullying perpetration and victimization at 8 years of age and violent offenses by the age of 31. Data were obtained for subjects enrolled in a population-based longitudinal birth cohort study. In 1989, 5813 8-year-old children (attrition 3.4%), and their parents and teachers, were surveyed about bullying. When 5405 subjects (attrition 10.2%) were 15–31 years of age, violent offenses were extracted from the Finnish National Police Register. We analyzed the data by sex and categorized bullying perpetration and victimization by frequency. Violent offenses were categorized by severity. Cox regression analyses estimated the hazard ratios (HRs) and 95% confidence intervals (95% CIs). When they were compared to males who had not been bullies at 8 years of age, frequent male bullies had an increased hazard for violent offenses (adjusted HR 3.01, 95% CI 2.11–4.33) and severe violent offenses (adjusted HR 2.86, 95% CI 1.07–7.59) as adults, even when the data were controlled for them being victims, parental education level, family structure and child psychopathology. Frequent female bullies also had an increased hazard for violent offenses, compared to those who had not bullied others (adjusted HR 5.27, 95% CI 1.51–18.40). Frequent male bullying was associated with higher odds for violent offenses compared to only bullying sometimes. Being a victim was not associated with violent offenses. Preventing childhood bullying could reduce violent offenses by both sexes.
