Abstract In this study, a numerical framework for joint rotation configuration models of a finger is proposed. The basic idea is to replicate the finger’s geometric posture observed when the human hand grasps a cylindrical object with various cross sections. In the model development, objects with the cross section adopted from the curves of order two (the family of conic sections) are taken into consideration to realize various finger postures. In addition, four different grasp styles, which simulate the individual-specific contact pattern between the surfaces of object and finger, are modeled and applied for the formulation of numerical models. An idea on how to change flexion/extension patterns in the middle of excursion of movement is proposed and discussed. Series of numerical studies have been conducted and analyzed to evaluate the proposed models. From the results, one can see the models’ feasibility and viability as a solution to describing finger’s flexion/extension movements (FEMs) for grasping patterns.

Values are like seeds that sprout, become saplings, grow into trees and spread their branches all around. To be able to think right, to feel the right kind of emotions and to act in the desirable manner are the prime phases of personality development. Building up of values system starts with the individual, moves on to the family and community, reorienting systems, structures and institutions, spreading throughout the land and ultimately embracing the planet as a whole. The culture of inclusivity is particularly relevant and important in the context of our society, nation and making education a right for all children.

The existing legislation determines the education as "an integral and focused process of teaching and upbringing, which represents a socially important value and shall be implemented so as to meet the interests of the individual, the family, the society and the state". However, even in this part, the meaning of the notion ‘socially significant benefit is not specified and allows for a wide range of interpretation [2]. Yet the more inconcrete is the answer to the question – "who and how should determine the interests of the individual, the family and even the state?" The national doctrine of education in the Russian Federation, which determined the goals of teaching and upbringing, the ways to attain them by means of the state policy regulating the field of education, the target achievements of the development of the educational system for the period up to 2025, approved by the Decree of the Government of the Russian Federation of October 4, 2000 #751, was abrogated by the Decree of the Government of the Russian Federation of March 29, 2014 #245 [7]. The new doctrine has not been developed so far. The RAE Academician A.B. Khutorsky believes that the absence of the national doctrine of education presents a threat to national security and a violation of the right of citizens to quality education. Accordingly, the teacher has to solve the problem of achieving the harmony of interests of the individual, the family, the society and the government on their own, which, however, judging by the officially published results, is the task that exceeds the abilities of the participants of the educational process.  The particular concern about the results of the patriotic upbringing served as a basis for the legislative initiative of the RF President V. V. Putin, who introduced the project of an amendment to the Law of RF "About Education of the Russian Federation" to the State Duma in 2020, regarding the quality of patriotic upbringing [3]. Patriotism, considered by the President of RF V. V. Putin as the only possible idea to unite the nation is "THE FEELING OF LOVE OF THE MOTHERLAND" and the readiness for every sacrifice and heroic deed for the sake of the interests of your Motherland. However, the practicing educators experience shortfalls in efficient methodologies of patriotic upbringing, which should let them bring up citizens, loving their Motherland more than themselves. The article is dedicated to solution to this problem based on the Value-sense paradigm of upbringing educational dynasty of the Kurbatovs [15].

Airborne LiDAR data: relevance of visual interpretation for forestry Airborne LiDAR surveys are particularly well adapted to map, study and manage large forest extents. Products derived from this technology are increasingly used by managers to establish a general diagnosis of the condition of forests. Less common is the use of these products to conduct detailed analyses on small areas; for example creating detailed reference maps like inventories or timber marking to support field operations. In this context, the use of direct visual interpretation is interesting, because it is much easier to implement than automatic algorithms and allows a quick and reliable identification of zonal (e.g. forest edge, deciduous/persistent ratio), structural (stratification) and point (e.g. tree/stem position and height) features. This article examines three important points which determine the relevance of visual interpretation: acquisition parameters, interactive representation and identification of forest characteristics. It is shown that the use of thematic color maps within interactive 3D point cloud and/or cross-sections makes it possible to establish (for all strata) detailed and accurate maps of a parcel at the individual tree scale.

The article raises the issue of the relationship of parent-child relationships and professional preferences in pedagogical dynasties. Particular attention is paid to the role of the family in the professional development of the individual. It has been suggested that there is a relationship between parent-child relationships and professional preferences.

This work represents a combination of different genres: cultural history, philosophical anthropology, and textbook. It follows a handful of different but interrelated themes through more than a dozen texts that were written over a period of several millennia. By means of an analysis of these texts, this work presents a theory about the development of Western Civilization from antiquity to the Middle Ages. The main line of argument traces the various self-conceptions of the different cultures as they developed historically. These self-conceptions reflect different views of what it is to be human. The thesis is that in these we can discern the gradual emergence of what we today call inwardness, subjectivity and individual freedom. As human civilization took its first tenuous steps, it had a very limited conception of the individual. Instead, the dominant principle was that of the wider group: the family, clan or people. Only in the course of history did the idea of what we know as individuality begin to emerge. It took millennia for this idea to be fully recognized and developed. The conception of human beings as having a sphere of inwardness and subjectivity subsequently had a sweeping impact on all aspects of culture, such as philosophy, religion, law, and art. Indeed, this conception largely constitutes what is today referred to as modernity. It is easy to lose sight of the fact that this modern conception of human subjectivity was not simply something given but rather the result of a long process of historical and cultural development.

We frequently speak of certain things or phenomena being built out of or based in others. This soda can is made of molecules, which are in turn made of atoms, which are in turn made of subatomic particles. The behavior of a crowd is based in the behaviors of and interactions between individual people—it behaves as it does in virtue of the individual behaviors and interactions. Making Things Up concerns the family of relations that such talk appeals to, which Karen Bennett calls “building relations.” Grounding is one currently popular such relation; so too are composition, property realization, and—controversially—causation. Building relations connect more fundamental things (like atoms) to less fundamental things (like soda cans). But what are we even talking about when we say that something is more fundamental than something else? This book illuminates the ideas of building and fundamentality, as they are deployed in metaphysics and elsewhere in philosophy. Bennett paints a picture of a hierarchically structured world, and makes good sense of otherwise somewhat cryptic talk of “in virtue of” and fundamentality.

Chemiluminescence cross sections for reaction of the individual spin–orbit states of metastable Ca(PJ03) with CH3I, CH2I2, and SF6 have been determined by the use of optical pumping state selection. This technique was also used to separate the chemiluminescence arising from the two excited metastable Ca 3P0 and 1D states. The spin–orbit dependence of the chemiluminescence pathway was found to be substantial for the CH3I and CH2I2 reactions and similar to that previously observed for halogen diatom and alkyl bromide reagents. By contrast, no spin–orbit effect was observed for Ca(3P0)+SF6. These results are discussed in terms of our previously presented model for the origin of spin–orbit effects in chemical reactions.

This paper makes an important, interdisciplinary contribution, to the ongoing debate on the transition from clanship to capitalism. Integral to this contribution is the important distinction between capitalism as an individualist ideology and capitalist societies where individualism is a widespread but not necessarily a universal ideology. His concern is not with the bipolar opposition of landlord and people which tends to dominate debates on the land issue in the Highlands. Instead, he focuses on material culture change in relation to landscape organisation, settlement patterns and morphology in order to examine how social relationships were structured during the critical period of estate re-orientation often depicted progressively as Improvement but regressively as clearance through the removal and relocation of population. His case study on Kintyre is particularly valuable. By scrutinising spatial as well as social relationships Dalglish demonstrates that clanship was based as much on daily practices of living as on an patrimonial ideology of kinship, practices which led the House of Argyll to attempt the reinvention of concepts of occupancy in order to emphasise the importance of the individual over the family through partitioned space.

It has long been suggested that in skeletal muscle, the ATP-sensitive K+ channel (KATP) channel is important in protecting energy levels and that abolishing its activity causes fiber damage and severely impairs function. The responses to a lack of KATP channel activity vary between muscles and fibers, with the severity of the impairment being the highest in the most glycolytic muscle fibers. Furthermore, glycolytic muscle fibers are also expected to face metabolic stress more often than oxidative ones. The objective of this study was to determine whether the t-tubular KATP channel content differs between muscles and fiber types. KATP channel content was estimated using a semiquantitative immunofluorescence approach by staining cross sections from soleus, extensor digitorum longus (EDL), and flexor digitorum brevis (FDB) muscles with anti-Kir6.2 antibody. Fiber types were determined using serial cross sections stained with specific antimyosin I, IIA, IIB, and IIX antibodies. Changes in Kir6.2 content were compared with changes in CaV1.1 content, as this Ca2+ channel is responsible for triggering Ca2+ release from sarcoplasmic reticulum. The Kir6.2 content was the lowest in the oxidative soleus and the highest in the glycolytic EDL and FDB. At the individual fiber level, the Kir6.2 content within a muscle was in the order of type IIB > IIX > IIA ≥ I. Interestingly, the Kir6.2 content for a given fiber type was significantly different between soleus, EDL, and FDB, and highest in FDB. Correlations of relative fluorescence intensities from the Kir6.2 and CaV1.1 antibodies were significant for all three muscles. However, the variability in content between the three muscles or individual fibers was much greater for Kir6.2 than for CaV1.1. It is suggested that the t-tubular KATP channel content increases as the glycolytic capacity increases and as the oxidative capacity decreases and that the expression of KATP channels may be linked to how often muscles/fibers face metabolic stress.
