A Nocardia sp.was found during an initial transmission electron microscopic (TEM) examination to have unusual intracellular bodies (ICB's) which do not appear to have been described previously in the literature. Most intracellular structures within bacteria have been classified as storage granules, a product of membrane invagination (i.e. mesosomes), or vacuoles. In bacteria there are no known intracellular membrane-bound organelles, and all internal membranes are invaginations of the unit membrane. Several microscopic-level examinations of the Nocardia sp. ICB's were initiated in order to determine their overall structure, classification, and internal constitution.Different TEM staining procedures were performed to determine possible molecular components of the ICB. In all of the staining protocols the ICB's showed a lack of electron density similar to the cell wall. Because the ICB's showed no affinity to any stain, it appeared they do not have strong positive charge (phosphotungstic acid), are not protein rich (en bloc uranyl acetate), lack glycogen and are not phosphate or sulphur rich (lead citrate), nor do they contain lipids or ribonucleic acids (osmium tetroxide).

Fundamental Insight

Hegelian speculative thought structures its movement through immediately reflected change of opposites. This exchange within elements isn’t merely shifting heterogeneous objects as it doesn’t concern objects’ ontological condition either. The speculative is the opening where the internal constitution and effectiveness of any element is questioned and revealed as simultaneous and immediate overcome of subject and object since the horizon of this opening concerns the absolute conditions of content and form and where the method self-reflected within premises is questioned too. For the true Concept of philosophy, Hegel shows, immediate beginning of knowledge is immediate beginning of Being; and advancement from pure indeterminateness to determinate being’s development supposes self-mediation of the same absolute immediacy, since ineluctably the speculative can’t admit suppositions’ arbitrariness. But such radical endeavor is accomplishable if the ultimate truth of Being (Wesen) is absolutely mediated immediacy — namely Actuality (Wirklichkeit) is the expression of absolutely self-mediated absolute immediate Identity. This fundamental principle is mirrored in the Trinitarian ground of the Hegelian speculative philosophy which is the main doctrinal postulate that permeates the entire metaphysical endeavor of the German thinker. In this, Hegel was singular, although the initiative of rebuilding philosophy without any prior supposition is not exclusively Hegelian. We can think about the Husserlian epoché as a project of redefining the limits of apodictic philosophy and the eidetic variation as the grounds for his fundamental insight (Einsicht). However, we have found that Husserlian phenomenology is yet deriving its entire structure within the realm of determinacy where the principle of determinate, and thus of formal identity, dominates. Hegelian identity is established precisely by an absolute rupture from formal relations and is an eminent case of a speculative opening towards the premises of a transcendent thinking whose eminence would ground the ultimate sight of genuine identity of appearance and essence, of thought and being. Keywords: Hegel, Husserl, Maldiney, speculative logic, absolute identity, immediacy, mediation, phenomenology.

The study of the earth's internal heat plays an important role in understanding the Earth's origin, internal constitution, and plate tectonics. The outflow of heat from the Earth's interior is, energy-wise, the most impressive terrestrial phenomenon. The present rate of heat loss is estimated to be about 1021 joules per year, which is orders of magnitude greater than the energy dissipation of earthquakes or heat loss from volcanic eruptions. Knowledge of terrestrial heat flow is essential in investigating the internal thermal field of the Earth. Initially focus has been on measurements of underground temperatures and thermal properties of geologic materials, assessment of sources and sinks of heat, institution of global data base, development of thermal models of crust and qualification of geothermal energy resources. During later stages, other implications of heat flow studies has also been recognized in fields such as paleoclimatology, global warming, exploration geophysics and hydrogeology. The International Heat Flow Commission – IHFC plays a guiding role in development of such investigations.

The Eu

This chapter examines the normative principles underlying the European Union's foreign policy and whether there are inconsistencies therein. Drawing on a distinction between the principles of sovereignty, human rights, and a common good, the chapter challenges the notion that the EU is a distinctive foreign policy actor. Each of these principles points to a different perspective on how international politics should be organized, and each would take the EU's foreign policy in different directions. The chapter shows that the unresolved tensions in the EU's internal constitution, between its cosmopolitan vocation and the ambition of (EU) nation building, are also reflected in the EU foreign policy.

The study of the internal constitution of the stars has advanced rapidly in the past few years, especially for those of the main sequence. The present summary is necessarily brief.For a star of uniform composition, whose interior is in radiative equilibrium, with or without a convective core, the constitution can be completely determined by successive approximations by quadratures, if there are given(a)the atomic composition(b)the equation of state, defining the mean molecular weight μ(c)the equation defining the opacity for the outflowing radiation(d)the equation defining the rate of liberation of energy per gram.
