Application of Phosphogypsum in Road Construction

Currently the Republic of Belarus is solving the problem of processing a by-product – phosphogypsum, formed in the process of phosphorric acid production. The issue of utilization of phosphogypsum is becoming more and more relevant, and there are several reasons for this: transportation of phosphogypsum to dumps and its storage require large capital investments and operating costs; when creating phosphogypsum dumps, it is necessary to alienate large areas, sometimes even cultivated land; storage of this material in dumps, even with the neutralization of soluble impurities and with the observance of dump operational rules causes irreparable harm to the environment. There are known studies of scientists on the use of phosphogypsum for road construction as a binder for strengthening soils, foundations and repair work. The paper presents the results of experiments on obtaining road-building materials from this waste without converting it into a binder. Based on the research, a technology for the preparation of asphalt concrete mixtures with the use of mineral powder in the form of phosphogypsum dihydrate has been developed.

“We’ve all Lost so Much”: The Experiences of Essential Family Caregivers’ Long Term Care Visitations During COVID-19

Family caregivers are integral to the care of long-term care (LTC) residents. COVID-19 public health policies initially restricted all essential caregivers from visiting LTC homes. In lieu of in-person visitations, caregivers were allowed technology-based visits then restrictive outdoor visits, followed by indoor visitations. This study aims to illuminate the experiences of essential caregivers’ as they visited their loved ones in LTC during COVID-19’s restrictive policies. We conducted seven caregiver focus groups (N=30) from Ontario and British Columbia, Canada. Thematic analysis and line-by-line coding were completed using NVivo. We found six themes that were common to all the visitation types: 1) “LTC Home disorganization” to facilitate visits and poor communication; 2) “Lack of staffing and resources”; 3) “Mistreatment from staff and management” as caregivers were seen as inconveniences; 4) “Shock and disbelief” when family members first saw their loved ones; 5) “Significant lack of person-centered or family-centered ethos” for example the residents’ needs were ignored such that their cognitive and physical impairments sometimes made visitations impossible, as well as the burden of multiple weekly COVID-19 tests; and, 6) “Collateral damage” in the form of trauma and irreparable harm to the relationships between residents and families. These results emphasized caregivers who ultimately felt betrayed and ignored by the broader healthcare system. Our findings provide an in-depth understanding of how COVID-19 public health policies have impacted the essential caregivers and the long-lasting impacts on residents and caregivers alike. Understanding caregiver’s experiences can inform future pandemic response policies and encourage more person-centered protocols.

Socially acceptable behaviour

In an age where organisations must have an online presence to compete and social media is virtually ubiquitous, it is essential that they have a policy on employees' social media use. Whether in the workplace or at home, a single post—even if it is not intended to be malicious—can cause irreparable harm

Theoretical and experimental study of interaction of macroheterocyclic compounds with ORF3a of SARS-CoV-2

The pandemic infectious disease (Covid-19) caused by the coronavirus (SARS-CoV2) is spreading rapidly around the world. Covid-19 does an irreparable harm to the health and life of people. It also has a negative financial impact on the economies of most countries of the world. In this regard, the issue of creating drugs aimed at combating this disease is especially acute. In this work, molecular docking was used to study the docking of 23 compounds with QRF3a SARS-CoV2. The performed in silico modeling made it possible to identify leading compounds capable of exerting a potential inhibitory and virucidal effect. The leading compounds include chlorin (a drug used in PDT), iron(III)protoporphyrin (endogenous porphyrin), and tetraanthraquinone porphyrazine (an exogenous substance). Having taken into consideration the localization of ligands in the QRF3a SARS-CoV2, we have made an assumption about their influence on the pathogenesis of Covid-19. The interaction of chlorin, iron(III)protoporphyrin and protoporphyrin with the viral protein ORF3a were studied by fluorescence and UV–Vis spectroscopy. The obtained experimental results confirm the data of molecular docking. The results showed that a viral protein binds to endogenous porphyrins and chlorins, moreover, chlorin is a competitive ligand for endogenous porphyrins. Chlorin should be considered as a promising drug for repurposing.

The Cultural Defence

This chapter considers how arguments based on cultural traditions and customary law influence the reasoning of judges in various jurisdictions through the use of cultural defences. A survey of cases reveals that judges consistently refuse to allow the introduction of evidence concerning litigants’ cultural backgrounds in legal proceedings. As explained here, the prescriptive version of cultural relativism calls attention to the context in which individuals act under cultural imperatives. It is the underlying theory that justifies culturally specific notions of reasonableness in criminal law and civil litigation. Although the defence is sometimes understood as limited to criminal cases, the chapter demonstrates how cultural factors also figure in cases involving exemptions and calculating damages in civil litigation. The chapter identifies several types of culture conflict, considers a theoretical framework for analysing cultural defences, and discusses practical difficulties associated with the implementation of the cultural defence policy. Anthropologists are often asked to serve as expert witnesses in these cases. How their involvement in the justice system may affect their professional reputations is also assessed. The final section offers suggestions as to likely new areas where cultural defences will be raised, such as military tribunals and educational systems. While proponents of the strategy contend that the courtroom door should be open to cultural argumentation, this does not mean the cultural factors should necessarily influence the disposition of the cases, particularly if the customs central to the dispute involve irreparable harm.

The Right to Protection of Forcibly Displaced Persons During the Covid-19 Pandemic

The unprecedented shutdown of borders and restrictions on migration in response to the Covid-19 pandemic have put the core principles of refugee protection to test and resulted in the erosion of the right to asylum and violations of the principle of non-refoulment (no one should be returned to a country where they would face torture; cruel, inhuman or degrading treatment; or punishment and other irreparable harm). Covid-19 is being used by some governments as an excuse to block people from the right to seek asylum and implement their nationalist agendas of border closures and anti-immigration policies.

One of the biggest challenges that the world is currently facing is that of environmental pollution, which is causing grave and irreparable harm to the natural world and human civilization. Worldwide innumerable deaths are being caused by water, air and soil pollution. Every nation is finding its permanent solution. The permanent solution is present in Islam which is a religion of purity and likes purification. It declares purification as half of Faith. It demands purification in every aspect related to human life. This article will highlight all the fields which require purification and the methods of implementation in daily life. If these teachings of Prophet Muhammad (PBUH) are applied the whole world can easily get rid of environment pollution.

Post-Truth (Mis)communication as Enigmatic Mystification and Misuse of Language

It would be erroneous to assume that language can only be used in positive sense and that it cannot be misused to cause instability and unrest in our professional as well as personal lives. On the contrary, language can be weaponised to cause irreparable harm/damage to vulnerable communities, ethnicities, marginalized populations, and deprived chunks of humanity. Language has innumerable forms such as genuine and authentic language, truthful and honest language, ingenuine and false language, and fake and deceptive language. Be that negative or positive aspect of language, it can be tilted either way as per one's will and choice; nevertheless, inauthentic and manipulative language can seldom have acceptability among the masses. The term ‘post-truth' stems from fabrication of truth and it has a deep connection with politics. Post-truth may be understood as a situation wherein the objective facts are less influential in shaping opinion, and emotions and personal beliefs are important to connect people. In this chapter, the authors have analyzed language in the age of post-truth.

Interim Measures in Antitrust Investigations: An Economic Discussion

After a period of dormancy, the topic of interim measures (IMs) in antitrust investigations has been brought back into the spotlight in the context of fast-moving digital markets. We analyze historical practices and criteria surrounding IMs in the United States and Europe. Then we present an economic model of the parameters underlying IMs, which can inform the decision of whether to pursue them. The two key parameters needed to determine the benefits of taking an IM are the relative magnitudes of irreparable harm to each party and the probability that the conduct is found to be anticompetitive. A resulting insight is that the overall size of the irreparable harms is not as relevant as their relative size (that is, asymmetry). Increasing both types of harm in the same proportion would not change the decision to use an IM. However, an increase in the overall size of irreparable harms increases the expected benefit from IMs as a tool, if they are used optimally. Finally, we examine the characteristics of the digital economy, finding that while such characteristics are likely to increase the benefits of IMs as a general tool, there is a need to carefully assess IM decisions on a case-by-case basis.
