Microstructure and Mechanical Properties of Inverse Nanocomposite Made from Polylactide and Hydroxyapatite Nanoparticles

Polymer nanocomposites have been extensively researched for a variety of applications, including medical osteoregenerative implants. However, no satisfactory solution has yet been found for regeneration of big, and so-called critical, bone losses. The requirement is to create a resorbable material which is characterised by optimum porosity, sufficient strength, and elastic modulus matching that of the bone, thus stimulating tissue regrowth. Inverse nanocomposites, where the ceramic content is larger than the polymer content, are a recent development. Due to their high ceramic content, they may offer the required properties for bone implants, currently not met by polymer nanocomposites with a small number of nanoparticles. This paper presents inverse nanocomposites composed of bioresorbable nano crystalline hydroxyapatite (HAP NPs) and polylactide (PLLA), produced by cryomilling and a warm isostatic pressing method. The following compositions were studied: 25%, 50%, and 75% of HAP NPs by volume. The mechanical properties and structure of these composites were examined. It was discovered that 50% volume content was optimal as far as compressive strength and porosity are concerned. The inverse nanocomposite with 50% nanoceramics volume displayed a compressive strength of 99 ± 4 MPa, a contact angle of 50°, and 25% porosity, which make this material a candidate for further studies as a bioresorbable bone implant.

Attention, Consciousness, and Linguistic Cooperation with AI

Contemporary debates on Artificial General Intelligence (AGI) center on what philosophers classify as descriptive issues. These issues concern the architecture and style of information processing required for multiple kinds of optimal problem-solving. This paper focuses on two topics that are central to developing AGI regarding normative, rather than descriptive, requirements for AGIs epistemic agency and responsibility. The first is that a collective kind of epistemic agency may be the best way to model AGI. This collective approach is possible only if solipsistic considerations concerning phenomenal consciousness are ignored, thereby focusing on the cognitive foundation that attention and access consciousness provide for collective rationality and intelligence. The second is that joint attention and motivation are essential for AGI in the context of linguistic artificial intelligence. Focusing on GPT-3, this paper argues that without a satisfactory solution to this second normative issue regarding joint attention and motivation, there cannot be genuine AGI, particularly in conversational settings.

Analysis of changes in regulatory framework of the russian federation on examination of relationship between diseases and profession for 40 years

The evolution of the national regulatory framework in the field of examination of connection between the disease and the profession for the period from the 80s of the twentieth century to the present is analyzed. Materials and methods. The regulatory framework of domestic professional pathology regarding examination of relationship between diseases and profession is evaluated Results. It was noted that for the specified period, in the normative acts the organizational issues of the examination of the connection between the disease and the profession did not have a satisfactory solution. A feature of most regulatory documents in the field under consideration, issued recently, is a certain logical inconsistency. Conclusions. To radically improve the current situation, it is necessary to immediately adopt for practical application the mandatory criteria, which prove the occupational origin of health disorders in workers.

CRIMINAL VICTIMIZATION ON LARGE-SCALE INVESTMENT SCAM IN INDONESIA

Mass scale investment fraud (Ponzi) schemes result in protracted suffering for the victims. In this article the author investigates this crime from a juridical normative, case, and conceptual approach. From the very start potential victims may fall to promises of lucrative and safe investment schemes. In the eyes of the more prudent, it would or should be obvious that the collaborative business offers as presented contains logical flaws, running against common sense and is at the outset illegal. Notwithstanding, victims seems to fall easily into this trap, lured by the promise of getting easy, quick, and huge investment returns. In the end, even when this fraudulent investment scheme unravels, the government of law enforcement seems to be unable to act decisively and offer a satisfactory solution. Slow and ineffective government response in the end exacerbate economic loss and victims suffering.

Factive inferentialism and the puzzle of model-based explanation

Highly idealized models may serve various epistemic functions, notably explanation, in virtue of representing the world. Inferentialism provides a prima facie compelling characterization of what constitutes the representation relation. In this paper, I argue that what I call factive inferentialism does not provide a satisfactory solution to the puzzle of model-based—factive—explanation. In particular, I show that making explanatory counterfactual inferences is not a sufficient guide for accurate representation, factivity, or realism. I conclude by calling for a more explicit specification of model-world mismatches and properties imputation.

OPTIMIZATION OF DAYLIGHT IN MUSUEMS AND ART GALLERIES

The aim of research is to identify the connection between daylight and museums. A museum may be a place where individuals will explore and learn the past, present and future of history, culture and science. Nowadays museum architecture emphasizes the museum for public interaction and best for education approach. The museum lighting is a challenge with daylight openings. This paper analyses the lighting environment of museum and art galleries with a satisfactory solution of daylight by using different passive design strategies without avoiding the harm to the artifacts and these parameters are good lighting solutions for existing as well as proposed building in terms of sustainability, energy consumption and perseveration. By using these parameters, we can also manage the artificial light and provide an advance solution in LED technologies and lighting solutions can be effectively used to retrofit a museum lighting environment and affecting the connection to the environment. Considering the benefits and challenges of introducing the daylight in museums and galleries. The typology of building and daylight parameters have directly impact on environment and create a visual shape in visitor’s mind. This study is based on majority of heritage buildings current deterioration state prevents those buildings from performing efficiently. A sustainable reuse approach for heritage buildings is considered essential. Old palaces that are usually reused with different functions mostly like museums for their considered interior beauty and unique rich designs. Function alteration along with a deteriorated state augments the energy consumption problem. The optimization of various skylight parameters is evaluated for their combined performance. The results disclose an improved performance which indicates the effectiveness of the energy and day lighting optimized strategies and techniques for heritage reuse. Daylight will help to create building more live, and a step to reducing the climate change and save our environment with global warming.

Two asymmetries in population and general normative ethics

This paper examines a dilemma in reproductive and population ethics that can illuminate broader questions in axiology and normative ethics. This dilemma emerges because most people have conflicting intuitions concerning whether the interests of non-existent beings can outweigh the interests of existing beings when those merely potential beings are expected to have overall net-good or overall net-bad lives. The paper claims that the standard approach to this issue, in terms of exemplifying the conflict between Narrow Person-Affecting Views and Impersonal Views, is not correct. It argues that, instead, we can approach the issue through the distinction between Symmetrical and Asymmetrical Views about the relative importance of positive and negative value. The paper also claims that Asymmetrical Views provide the most intuitively satisfactory solution to the dilemma and can in addition be defended independently on further grounds. Keywords: person-affecting views, impersonal views, symmetry, asymmetry

Perceptual Idealism and Phenomenal Geometry

My account of 3D vision attempts to preserve many of the traditional commitments of naïve realism, whilst rejecting its central tenet of mind-independence. In this fourth post I explain why this provides a more satisfactory solution to variations in scene geometry with viewing conditions than recent ‘four-dimensional’ accounts.

Well-being capital and government’s intervention to dam’s affected residents: Pak Mun Dam, Thailand

Government plays an important role as a well-being capital provider through policies, strategies, or even direct provision to local residents to improve their livelihoods. Pak Mun Dam is one of the most controversial dams in Thailand, and government intervention is needed to solve the issues the dam has created. This study tests the premise that government intervention will impact overall well-being only through structural means by providing strategy and policies related to social and economic well-being. Government training programs and government services will impact over all well-being through social well-being. A satisfactory solution to the Pak Mun Dam situation will impact overall well-being through economic well-being. In this study a number of items, related to different well-being dimensions, were examined. The findings suggest that appropriate policy must address the four significant items which surfaced in the economic well-being measure and ten items in the social well-being dimension.

Reimagining academic conferences: Toward a federated model of conferencing

What should the post-COVID conference look like? In our attempt to answer this question, we first describe the primary functions and affordances of conferences. Our frank appraisal reveals the breadth of reasons why academics attend conferences, and how conference attendance often blends personal and professional motivations. We also elaborate some of the shortcomings of in-person conferences, spanning personal, professional, and societal concerns. Recent alternative (virtual) formats for convening scholars provide means for alleviating some of these shortcomings, but do not seem entirely up to the task of providing a fully satisfactory solution to all that conferencing can be. Moreover, we extrapolate from prior history and ongoing trends to predict that technological solutionism to conferencing is likely to unleash both positive and negative dynamics, some of which will exacerbate current ills in our profession. We then sketch out a values-based approach that can serve as a basis for reimagining academic conferences. This vision promotes a federated model of conferencing, grounded in principles of inclusion, diversity, community, and environmental stewardship.
