During embryonic life, individuals should adjust their phenotype to the conditions that they will encounter after birth, including the social environment, if they have access to (social) cues that allow them to forecast future conditions. In birds, evidence indicates that embryos are sensitive to cues from clutch mates, but whether embryos adjust their development to cope with the expected level of sibling competition has not hitherto been investigated. To tackle this question, we performed a ‘match versus mismatch' experimental design where we manipulated the presence of clutch mates (i.e. clutch size manipulation) and the real (postnatal) level of sibling competition (i.e. brood size manipulation) in the yellow-legged gull ( Larus michahellis) . We provide evidence that the prenatal cues of sibling presence induced developmental changes (such as epigenetic profiles) that had programming effects on chick begging behaviour and growth trajectories after hatching. While receiving mismatching information favoured chick begging and growth, this came at the cost of reduced antioxidant defences and a premature loss of telomeres. Our findings highlight the role of the prenatal social environment in developmental plasticity and suggest that telomere attrition may be an important physiological cost of phenotype–environment mismatch.

Abstract Groups of pastors in Siebenbürgen issued three confessions of faith between 1557 and 1572 – the Consensus Doctrinae (1557), the Brevis Confessio (1561), and the Formula pii consensus (1572) – in which they defended their view of the Lord’s Supper in line with Wittenberg teaching against medieval teaching and against challenges from Swiss Reformed theologians. These documents reflect both conditions in Siebenbürgen and the streams of thinking in the wider environment of Luther’s and Melanchthon’s followers. The Brevis Confessio was published with memoranda from four German universities and letters from several theologians supporting its formulations. The first two documents largely tend toward Luther’s expression of the doctrine of the real presence, while the third uses language employed by both Wittenberg teachers, avoiding controversial expressions. This last confession strives toward consensus among the followers of the Wittenberg preceptors.

The purpose of this project is to build a prototype of compact flexural fatigue testing machine and to strive for an easy working-environment as required by the users besides cutting the cost of the machining. This particular project is about to build the prototype of compact flexural fatigue testing machine in compact mode. In this project, the prototype will be functioning 60% similar to the real fatigue machine which is Dynamic Fatigue Testing Machine (INSTRON) due to timer counter, frequency and load applied. But the new invention is this prototype was using the concept of electromagnetic force relay that will apply to the specimen using the application of basic electronics. The motion sensor also being applied to this prototype to achieve accurate results when the specimen breaks up after undergoes a fatigue failure.

In a recent article on the medieval dogma of transubstantiation, Gary Macy builds upon the works of Hans Jorissen and James F. McCue to question the validity of Jaroslav Pelikan's claim that “at the Fourth Lateran Council in 1215, the doctrine of the real presence of the body and blood of Christ in the Eucharist achieved its definitive formulation in the dogma of transubstantiation.” Macy demonstrates that through most of the thirteenth century, the majority of theologians did not, in fact, consider Lateran IV's decree the final word on eucharistic theology. The debate over precisely how the real presence of Christ occurred in the eucharist was far from closed.


The study examined the arguments and counterarguments within the scientific discussion on commercial banks credit and the performance of real sector in Nigeria. The main objective of the study is to examine the effect of commercial banks credit on the performance of the real sector in Nigeria.Data was sourced from Central Bank of Nigeria Statistical Bulletin. A systematization literary approach for data analysis was Regression Analysis. Findings revealed that bank credit and bank lending rate does not have significant impact on real sector performance in Nigeria. It was showed that there was a positive and significant relationship between agricultural credit guarantee scheme fund and agricultural production in Nigeria. The study therefore recommends that banks should be directed to channel their credits towards the real sector to facilitate overall economic growth and development in Nigeria. It was recommended that there is the need policies that will favor the revamp of the agricultural sector in Nigeria should be given pride of place. Also, monetary authority through the Central Bank of Nigeria should create adequate policies and strategies towards deepening of the financial sector and reducing the cost of credit/loans so as to enhance productivity and consequently enhance the growth of the key sectors of economy such as manufacturing sector.

The article presents St. Augustine’s concept of the Eucharist, relating it to the ecclesiological dimension that the concept of corpus Christi can have, showing its link with the paupers, since the Incarnate Word became pauper when assuming the human condition. Reference is also made to the charitable work of Giacomo Cusmano (1804-1885), as well as medieval controversies about the real presence of Christ in the Eucharist, and its evolution until the Second Vatican Council.

Haun saussy opens his influential discussion of past and present conceptions of comparative literature, “exquisite cadavers Stitched from Fresh Nightmares,” by linking them in an apparently historic claim to victory: “Comparative literature has, in a sense, won its battles” (3). The ambiguous nature of that claim, and the real subject of Saussy's ensuing discussion, is indicated, however, by the qualifying phrase “in a sense.” In another sense, Saussy implies, the achievements of comparative literature remain open to debate. For, despite the widespread adoption by national-literature departments of comparative literature's theoretical methods of inquiry, comparative approaches to literature continue to be considered inessential or secondary to the defining aim of national-literature departments—investigating and describing the reality of historically grounded national traditions and identities. Saussy's “sense” of victory is thus snatched from the jaws of an unapologetic sense of defeat:What needs propagating is the comparative reflex, the comparative way of thinking, not the departmental name; and if those are to spread at the cost of identity and institutional reward, so much the worse for identity.—It so happens that identity is the pivot of our triumph—and our wraithlikeness.

Both “animals” and “religion” are contentious concepts, with many possible meanings and associations. This chapter takes animals to be eukaryotes distinct from protists, plants and fungi, and “religion” as the attempt to “live a dream.” I describe four principal ways of dreaming animals: triumphalist humanism (for which only “human” beings are of any interest); traditional notions of good husbandry (which requires “human” beings to care for the non-human, within limits set by human interests); notions of metempsychosis and transformation (where “human” and “non-human” are constantly shifting characters); and awakening to the real presence of others, and so—paradoxically—evacuating them of merely “religious” meaning.
