Adult horned beetles (Coleoptera, Scarabaeidae, Dynastinae) such as Trypoxylusdichotomus (Linnaeus, 1771) exhibit bark-carving behaviors to feed on tree sap, in part by using small projections of the clypeus. However, in the present experiments, adult horned beetles (T.dichotomus and Dynasteshercules (Linnaeus, 1758)) used their mandibles and not the projections of the clypeus to carve bark. Our findings show the presence of completely engaged mandibular interlocking, gear-like surface structures in molar areas that guide mandible opening and closure, and lead to completely synchronous movements of adult horned beetle mandibles. Three-dimensional shapes of these mandibular gear-like structures are complex and remained in contact after the death of a beetle. Moreover, adult horned beetles often performed bark-carving behaviors using only the mandible of one side, suggesting that the primary role of the mandibular gear-like structure is to prevent breakage of the mandible by transmitting load from one mandible to the other. Among the 22 Dynastinae and 16 other beetle species examined (not Dynastinae), the gear-like structure was found in all the Dynastinae species and in no other species.

Fourth Rib

To assess the relative contributions of the different groups of inspiratory intercostal muscles to the cranial motion of the ribs in the dog, we have measured the axial displacement of the fourth rib and recorded the electromyograms of the parasternal intercostal, external intercostal, and levator costae in the third interspace in 15 anesthetized animals breathing at rest. In eight animals, the parasternal intercostals were denervated in interspaces 1-5. This procedure caused a marked increase in the amount of external intercostal and levator costae inspiratory activity, and yet the inspiratory cranial motion of the rib was reduced by 55%. On the other hand, the external intercostals in interspaces 1-5 were sectioned in seven animals, and the reduction in the cranial rib motion was only 22%; the amount of parasternal and levator costae activity, however, was unchanged. When the parasternals in these animals were subsequently denervated, the levator costae inspiratory activity increased markedly, but the inspiratory cranial motion of the rib was abolished or reversed into an inspiratory caudal motion. These studies thus confirm that, in the dog breathing at rest, the parasternal intercostals have a larger role than the external intercostals and levator costae in causing the cranial motion of the ribs during inspiration. A quantitative analysis suggests that the parasternal contribution is approximately 80%.

Important Basis

Over the past few decades, two-factor models of social cognition have emerged as the dominant framework for understanding impression formation. Despite the differences in the labels, there is wide agreement that one dimension reflects sociability potential, and the other, competence. One way in which the various two-factor models do clearly differ, however, is in the way the dimensions incorporate or produce evaluations of morality. Aristotle saw morality as the most important basis on which to form positive evaluations, because competence and sociability could only be virtuous, sincere, and trustworthy if expressed through a moral character. This chapter highlights research demonstrating the unique and possibly primary role of morality in social cognition. We clarify the dynamic, interactive, and conjoint effects of morality on social perception, and argue morality, competence, and sociability are three influential and interactive dimensions of social perception.

Bacteria and mammals have co-evolved with one another over millennia, and it has become impossible to interpret mucosal immunity without taking the microbiota into consideration. In fact, the primary role of the mucosal immune system is regulating homeostasis and the host relationship with the microbiota. Bacteria are no longer seen as simply invading pathogens, but rather a necessary component to one’s own immune response. On the one hand, the microbiota is a vital educator of immune cells and initiator of beneficial responses; but, on the other, dysbiosis of microbiota constituents are associated with inflammation and autoimmune disorders. In this review, we will consider recent advances in the understanding of how the microbiota influences host mucosal immunity, particularly the initial development of the immune response and its implications.

The Relationship

The position of women in society is often regarded as second-class, making the backward condition and used as scapegoats for the backwardness of a society and nation. And even worse, the treatment of women by putting it as second-class communities are often mentioned as religious injunctions of Islam. On the other hand, there are those who want to empower women by giving women the freedom to freely, by demanding their equality with men in all aspects, without considering the differences that have been given by God to men and women. So what happens is the increasing number of family breakdown leading to divorce and loss of sosial community building. Hence<br />the need for reconstruction of a fair idea about the position of women, both on the relationship of women with men, as well as the position and role of women in family and society. Based on observations of the hadiths of the Messenger of Allah, it was shown that a Muslim woman at the time (shahabiyah) has had a very complex role in the community. Nevertheless, they do not leave their primary role in the family and still uphold the ethics<br />of religion in the publik domain.

The surface structures of music and speech should coincide in musical prosody. Two processing systems have thus to be integrated, one devoted to the surface structure of speech, the other to that of music. This article is in two parts: a review of data on speech and music production and hearing, and two experimental studies on the synchronization between a rhythm and spoken sounds. In the first part, a comparison between some intensity and timing parameters that characterize the unfolding of spoken strings and of musical sequences is presented. Data from studies on performers (speakers, musicians) and listeners are compared with regard to spontaneous rates, location and duration of pauses, duration of sounds, and periodic occurrence of accents. In the second part, the ability to control the correspondence between taps and words is examined. Two experimental studies on 6-year-old children focus on the role of musical training. The reproductions of simple rhythms and simple sentences or onomatopoeias were analyzed as well as the coordination between a rhythmic sequence of taps and a spoken string. Young musicians succeeded better than nonmusicians of the same age in the synchronization between their verbal production and their motor accompaniment, mainly because they more markedly anticipated the musical string in which they integrated the spoken sounds subsequently. The results are discussed in relation to the acoustic, motor, and cognitive processes involved in the coordination of the two temporal strings.

The attractiveness of colored spheres was compared in the field for several tabanid species. Black and red spheres were highly attractive to all the species. Tabanus illotus was attracted nearly equally to black, gray, and white silhouettes. The attractiveness of gray and white spheres for the other species decreased rapidly with increasing reflectance. Green and yellow spheres were unattractive for all species. Two-dimensional black silhouettes attracted only a small number of tabanids. Three-dimensional black silhouettes with plane surfaces attracted larger numbers of flies. Glossy black silhouettes with convex curvature in the vertical plane were much more attractive than other silhouettes. Interpretations of these results are presented.

This study examined the structure of professional women's attitudes toward the dual roles encompassed in motherhood and occupational career. A dual-role scale of 19 items was constructed and with other scales given female faculty members each with at least one child at home. Factor analytical techniques produced a three-dimensional attitudinal model: the career as enriching family life, role equality, and primary role priority. Relationships between these anitudinal components and other measures of feminine involvement and demographic variables are presented.

Abstract In the In(1LR)pn2a rearrangement, the 1A-2E euchromatic segment is transposed to the vicinity of X heterochromatin (Xh), resulting in position effect variegation (PEV) of the genes in the 2BE region. Practically the whole X-linked heterochromatin is situated adjacent to variegated euchromatic genes. Secondary rearrangements showing weakening or reversion of PEV were obtained by irradiation of the In(1LR)pn2a. These rearrangements demonstrate a positive correlation between the strength of PEV of the wapl locus and the sizes of the adjacent heterochromatic blocks carrying the centromere. The smallest PEV-inducing fragment consists of a block corresponding to ~10% of Xh and containing the entire XR, the centromere, and a very proximal portion of XL heterochromatin. Heterochromatic blocks retaining the entire XR near the 2E region, but lacking the centromere, show no PEV. Reversion of PEV was also observed as a result of an internal rearrangement of the Xh blocks where the centromere is moved away from the eu-heterochromatin boundary but the amount of X heterochromatin remaining adjacent to 2E is unchanged. We propose a primary role of the X pericentromeric region in PEV induction and an enhancing effect of the other blocks, positively correlated with their size.
