Saito says that Marx’s major achievement, Capital, is “a theory of metabolism.” Any emphasis on rifts or ruptures has the risk of assuming that nature is in harmony or in balance until capitalism disturbs it. But nature is never in balance, even without humans. It is always changing, evolving, but with “punctuated equilibriums,” such as the Cambrian explosion, with many species evolving as others go extinct. The rule of the dinosaurs and their eventual extinction had nothing to do with humans (despite what movies may depict). Nature, like society, is a dialectical process full of change and contradiction, as Engels brilliantly shows in his Dialectics of Nature, a book frowned on by many, yet still pertinent.

This paper builds a dynamic industry model with heterogeneous firms that explains why international trade induces reallocations of resources among firms in an industry. The paper shows how the exposure to trade will induce only the more productive firms to enter the export market (while some less productive firms continue to produce only for the domestic market) and will simultaneously force the least productive firms to exit. It then shows how further increases in the industry's exposure to trade lead to additional inter-firm reallocations towards more productive firms. These phenomena have been empirically documented but can not be explained by current general equilibrium trade models, because they rely on a representative firm framework. The paper also shows how the aggregate industry productivity growth generated by the reallocations contributes to a welfare gain, thus highlighting a benefit from trade that has not been examined theoretically before. The paper adapts dynamic industry model to monopolistic competition in a general equilibrium setting. In so doing, the paper provides an extension of Krugman's (1980) trade model that incorporates firm level productivity differences. Firms with different productivity levels coexist in an industry because each firm faces initial uncertainty concerning its productivity before making an irreversible investment to enter the industry.

The importance of virtue to St. Thomas' moral theology is well-known, but his stress on the need to grow the virtues has received less attention. Led by charity, the infused theological and cardinal virtues grow through a further influx of grace given by God as a reward for virtuous acts or "merits" performed through cooperative grace. While this takes steady application, Aquinas' early work does not suggest that it is especially difficult. But following his mid-career discovery of the late works of St. Augustine, a stress on human frailty and need for divine dependency come into sharper focus. Sin's effects are viewed as more damaging and moral struggle as more of a problem. Increasingly the question "how does infused virtue grow?" involves the further question "and how does infused virtue survive?"

SOME REMARKS ON THE UNTOLD MARITIME HISTORY OF THE ALBANIANS Although the Albanians are one of the peoples that have been living on the Mediterranean for thousands of years, we are probably the only Mediterraneans that have almost never given any importance to the developement of maritime history studies. It seems in fact unbelievable how few studies about the sea are undertaken by Albanian scientis in general and from historians in the particular. The Albanians are a Mediterranean people that enjoy a key strategic position in the Central Mediterranean, bordering two of the most important maritime spaces of this great sea, i.e. the Adriatic and the Ionian sea, they have had a limited role in the naval history of the Middle Ages. Until the 15th century, the Adriatic Sea was a maritime space dominated exclusively by the Venetians. The Hungarian influence in Dalmatia and the Ottoman presence in Albania eventually ended the Venetian monopoly on the Adriatic Sea. The new situation that would last for four centuries gave new opportunities to the Croats and the Albanians, but also to the Anconitans on the Italian coast. The growth of maritime trade in the Adriatic sparked the developement of the economy of the eastern Adriatic coast and the interaction of Albanians with the sea and the Mediterranean world reached the highest levels in our entire history during this period, namely the central centuries of Ottoman rule (16th - 18th centuries) when the Adriatic was transformed from a Venetian “lake” into a sea exploited by various actors also, such as Croats, Albanians, and Spaniards. In the comparative aspect, the sixteenth century is not only the golden age of the Ottomans, but also of the Spaniards, the Portuguese, the Algerians, the Venetians, the Ragusans, and the French. In general, it is the golden age of the Mediterranean. Thus, the participation and involvement of the Albanians in this Mediterranean civilization awakening, in this revival of the Mediterranean, is neither shameful nor unnatural. It is the expected and inherent consequence of a comprehensive, panMediterranean trend.

A tanulmány egy Makó határában 2009 során elvégzett, több korszak emlékanyagát eredményező próbafeltárás alkalmával előkerült 4. századi szarmata temetkezést mutat be. A kutatóárokban előkerült sír vélhetőleg egy nagyobb kiterjedésű temető részét képezhette. A tanulmány röviden kitér a környéken található további szarmata temetőkre.

This paper, an overview • of research pursued at NML towards sustainable alumina production, ',deals with: (a) a chemical beneficiation of red mud to recover all its constituents, and (b) a novel process to reduce the alumina and soda content of red mud using mechanochemical activation (MA) of bauxite. As a part of the study on chemical-beneficiation of red mud, phase stability in the system Fe203-A1203-Na2CO3-C has been investigated using free energy minimization. Using these results, a process involving solid-state carbothermic reduction of red mud in the presence of soda, water leaching for alumina recovery and magnetic separation of leach residue for the separation of iron and TiO2 rich _fraction has been evaluated. Experimental results are explained using extensive X-ray diffraction and SEM-EDS studies on various solid residues generated in the different stages of the process. Mechanical activation of bauxite is investigated: (a) as pre-treatment to the Bayer process; and (b) mechanochemical leaching of bauxite, i.e. simultaneous milling and leaching of bauxite. The superiority of mechanochemical leaching over the existing Bayer 1. process practice and MA as pretreatment has been established. Using the novel process the approach of mechanochemical leaching, reduction in soda content of red mud to less than 1% and alumina content to less than half is possible with additional benefits in terms of moderation in process condition, simplicity of the process and efficient utilization of energy. Merits of the investigated processes have been highlighted vis-à-vis previous studies on red mud utilization and minimization of its environmental impact.
