Two Bodies

Within the Western slope of the Southern Urals, there are plenty of basite dyke complexes of Riphean to Vendian among Precambrian terrigenous-carbonate formations. In metamorphic formations of the Taratash complex (Archean to Early Proterozoic, the northern closure of the Bashkirian meganticlinorium) there was observed the andesitic dyke with isotopic age of 71±1 Ma (U-Pb SHRIMP II on zircons) and near Bakal two bodies of gabbroids with zircons of similar ages were found. These are the first evidence of possible Mezozoic magmatism in this region.

Kinetic Moment

The controlled motion of a body in a central gravitational field without mass flow is considered. The possibility of moving the body in the radial direction from the center of attraction due to changes in the kinetic moment relative to the center of mass of the body is shown. A scheme for moving the body using a system of flywheels located in the same plane in near-circular orbits with different heights is proposed. The use of the spin of elementary particles is considered as flywheels. It is proved that using the spin of elementary particles with a Compton wavelength exceeding the distance to the attracting center is energetically more profitable than using the momentum of these particles to move the body. The calculation of motion using hypothetical particles (gravitons) is presented. A hypothesis has been put forward about the radiation of bodies during accelerated motion, which finds indirect confirmation in stellar dynamics and in an experiment with the fall of two bodies in a vacuum. The results can be used in experiments to search for elementary particles with low energy, explain cosmic phenomena and to develop transport objects on new physical principles.

Two Bodies

This chapter embarks on a study of the two-body problem in general relativity. In other words, it seeks to describe the motion of two compact, self-gravitating bodies which are far-separated and moving slowly. It limits the discussion to corrections proportional to v2 ~ m/R, the so-called post-Newtonian or 1PN corrections to Newton’s universal law of attraction. The chapter first examines the gravitational field, that is, the metric, created by the two bodies. It then derives the equations of motion, and finally the actual motion, that is, the post-Keplerian trajectories, which generalize the post-Keplerian geodesics obtained earlier in the chapter.

Two Bodies

This chapter presents an overview of the adjudicative bodies of the Council of Europe—namely, the European Court of Human Rights (established by the European Convention on Human Rights and Fundamental Freedoms (ECHR)) and the European Committee of Social Rights—and outlines their mandates with regard to integrating UN human rights treaties. It analyses how these two bodies have cited the Convention on the Rights of Persons with Disabilities (CRPD). The dataset was forty-five cases dealt with by the Court and two collective complaints decided by the Committee that cite the CRPD up to 2016. Notwithstanding the relatively small size of the dataset, the conclusions are that the Council of Europe system has yet to engage seriously in the CRPD’s jurisprudential opportunities. The reasons for this cannot be ascertained from a desk-based methodology, and further research is required.

Shed Light

By the late second century, early Christian gospels had been divided into two groups by a canonical boundary that assigned normative status to four of them while consigning their competitors to the margins. The project of this volume is to find ways to reconnect these divided texts. The primary aim is not to address the question whether the canonical/non-canonical distinction reflects substantive and objectively verifiable differences between the two bodies of texts—although that issue may arise at various points. Starting from the assumption that, in spite of their differences, all early gospels express a common belief in the absolute significance of Jesus and his earthly career, the intention is to make their interconnectedness fruitful for interpretation. The approach taken is thematic and comparative: a selected theme or topic is traced across two or more gospels on either side of the canonical boundary, and the resulting convergences and divergences shed light not least on the canonical texts themselves as they are read from new and unfamiliar vantage points. The outcome is to demonstrate that early gospel literature can be regarded as a single field of study, in contrast to the overwhelming predominance of the canonical four characteristic of traditional gospels scholarship.

Two Bodies

In modern democracies, the legislative power is vested in parliaments with diverse organizational structures. Bicameral legislatures, requiring concurrent deliberation by two bodies, are present in about one-third of the world’s countries. Bicameralism typically serves the important purpose of accommodating the representation of heterogeneous interests from distinct social cleavages or geographic entities, but it is also associated with advantages such as greater stability of policies, increased accountability, and better quality of legislation. These benefits, however, only arise under specific circumstances, and the greater procedural complexity brought about by two chambers is not without costs. Disagreement between the two chambers often leads to costly legislative gridlock. Bicameralism can also open the door to pressure groups advancing their requests for favorable legislation when the chambers do not have time to carefully consider its consequences. The constitutional choice of bicameralism and its optimality ultimately rest on the subtle balance between its costs and benefits.

Significant Question

This chapter explores the interaction between domestic and international law in relation to the state’s engagement with treaties. Treaty engagements are important mechanisms through which states conduct their foreign relations. The domestic allocation of responsibility for the making and unmaking of treaties is therefore a significant question of the constitutional separation of powers in the realm of foreign relations law. Treaties are also international legal instruments, facilitating the development of international law and international institutions. The domestic and international law of treaties therefore both concurrently regulate the state’s power to join and leave treaties. This chapter examines the relationship between these two bodies of law in this regard, setting out developments in domestic jurisdictions establishing constitutional limits on the executive’s power to enter and exit treaties, and addresses the possible impact of these constitutional developments in the international law of treaties.

Two Bodies

About 10 X-ray binaries in our Galaxy and LMC/SMC are considered to contain black hole candidates (BHCs). Among these objects, Cyg X-1 was identified as the first BHC, and it has led BHCs for more than 25 years(Oda 1977, Liang and Nolan 1984). It is a binary system composed of normal blue supergiant star and the X-ray emitting compact object. The orbital kinematics derived from optical observations indicates that the compact object is heavier than ~ 4.8 M⊙ (Herrero 1995), which well exceeds the upper limit mass for a neutron star(Kalogora 1996), where we assume the system consists of only two bodies. This has been the basis for BHC of Cyg X-1.
