The genus Dicranostomus belongs to the very few Orthoptera with elongated mandibular processes, here called tusks. However, it is also one of the least studied genera from whose two species only one female and two males have been known so far. We present additional material from both species and sexes that confirms that the males have the relatively longest (2–2.8 times pronotal length) tusks of all Orthoptera. Surprisingly, the females of both species differ in this character: females of D. monoceros have tusks and those of D. nitidus do not. Based on a comparison with other species, we hypothesize that the species use holes that males can defend and use to monopolize the females.

This chapter includes some additional material on homotopies. In particular, for a smooth variety V, there exists an “inflation” homotopy, taking a simple point to the generic type of a small neighborhood of that point. This homotopy has an image that is properly a subset of unit vector V, and cannot be understood directly in terms of definable subsets of V. The image of this homotopy retraction has the merit of being contained in unit vector U for any dense Zariski open subset U of V. The chapter also proves the continuity of functions and homotopies using continuity criteria and constructs inflation homotopies before proving GAGA type results for connectedness. Additional results regarding the Zariski topology are given.

In this article, the author highlights the worthy contribution of the people of Uzbekistan, along with other peoples, to the victory over fascism in World War II in a historical aspect. This approach to this issue will serve as additional material to previously published works in international scientific circles

The architecture of the kidney of birds (and also reptiles) is, unlike in mammalians, mainly determined by the organization of the blood vascular system. Besides arterial supply and venous drainage, the renal portal system forms a main structural component. While the latter was often regarded as a “primitive” feature in the literature, morphological and physiological data reveal its great functional importance.Microvascular corrosion casts studied in the scanning electron microscope permit the visualization of minute vessels, retaining their 3D-arrangement. Additionally, when compared with graphical reconstructions of serial sections, this method avoids several inherent artifacts like fixation and dehydration shrinkage as well as the compression of the object by the sectioning blade. Most of the studies on avian kidneys with this technique used the domestic chicken as a model. In order to provide additional material for comparative and functional studies, data on the intrarenal vascular structure of other species are required.

Perioperative visual loss is a rare but severe complication after surgery in prone position. One of several mechanisms is direct ophthalmic compression. This can be avoided through optimal positioning and padding of the head, but position and integrity of the eyes need to be checked at regular intervals. We describe the use of a conventional video laryngoscope during vascular surgery in prone position as a simple solution for intermittent monitoring of external integrity of the eyes and size of the pupils. This requires no additional material and allows documentation of the findings. Our method might reduce complications and improve patient outcome.

ABSTRACT Background Behavioral change communication (BCC) promotes skills and knowledge to improve infant and young child feeding, but without additional material inputs, recipients must develop strategies to translate knowledge into action. Using data from the Alive & Thrive initiative in Bangladesh (2010–2014), we aimed to test whether households receiving the intensive intervention (opposed to the nonintensive intervention) increased expenditures on key foods for mothers and children (e.g., foods that were promoted by the intervention and also changed in maternal and child diets). Methods The intensive intervention provided interpersonal counseling, community mobilization, and mass media campaigns to promote breastfeeding and complementary feeding. A cluster-randomized design compared 20 subdistricts randomly assigned to the intensive (4281 households) or nonintensive (4284 households) intervention. Measures included food and nonfood expenditures, dietary diversity, and women's economic resources. Linear and logistic regression tested difference-in-differences (DD) in expenditures and dietary diversity, accounting for subdistricts as clusters, and the association between maternal and child consumption of specific food groups and corresponding food expenditures. Results Expenditures on eggs and flesh foods increased more in intensive areas than in nonintensive areas by 53 (P < 0.01) and 471 (P < 0.01) taka/mo, respectively. Household food expenditures increased more in intensive areas by 832 taka (P = 0.02), whereas changes in nonfood expenditures did not differ. Women's employment and control of income increased more in intensive areas by 12 (P = 0.03) and 13 (P < 0.01) percentage points, respectively, while jewelry ownership decreased more by 23 percentage points (P < 0.01). Higher expenditures on food groups were reflected in higher consumption by women and children. Conclusions Recipients in the intensive intervention mobilized additional resources to improve diets, reflected in increased expenditures and consumption of promoted foods. BCC interventions should document how recipients produce desired results without additional material inputs, particularly for behaviors that likely require additional resources. This trial was registered at clinicaltrials.gov as NCT01678716.

In a departure from car-centered analyses of the automobility systems, this article highlights the importance of motorcycles and motorcycling in the mobility practices of socialist countries. For at least half of the existence of socialist mobility systems, and especially during the 1950s and 1960s, there were more motorcycles on the roads than cars. Motorcycling was important in commuting, for the mobility of lower-ranking administrative personnel in the countryside, and for mass tourism and leisure. Although in that era maintenance and repair practices were equally central to motorcycling and car-driving, the distinction between user-owner and mechanic was much more fluid in the case of motorcyclists. As a result, the centrality of maintenance and repair to socialist-era motorcycling offers an ideal opportunity to enrich current interdisciplinary conversations about breakdown, maintenance, and repair. Building on the car-centered research into maintenance and repair activities, I add additional material on the nature, types, and complexity of such practices for motorcycling. I outline nine forms of material engagement with motorcycles that reference, but transcend, the current dichotomies between necessity and pleasure, the formal and the informal, the technical and the aesthetic, and the repair of existing objects and the creation of new ones.

Textual evidence preserved in two still unpublished manuscripts strongly suggests that there once existed an alternative version of Miskawayh’s Fawz al-aṣghar, the Minor Book of Triumph. The article discusses possible explanations for why Miskawayh may have composed two recensions of his Fawz and compares structure and content of the alternative version with the edited standard version. The one passage which is contained in the alternative Fawz only is presented in Arabic with an English translation. Part of this additional material is parallel to al-Fārābī’s Iḥṣā’ al-‘ulūm, namely its division of natural sciences, and may ultimately derive from a no longer extant treatise by Paul the Persian. An appendix provides the Arabic text and English translation of a hitherto unknown fragment of al-Balkhī in which he discusses Plato’s saying that the world has a causative, but no temporal beginning.

The development and numerical implementation of a constitutive model for jointed rock media is the subject of investigation in this paper. The constitutive model is based on the continuum assumption of strain-partitioning among the elastic rock matrix and joint sets with nonlinear normal and shear responses. Rate equations for the stress-strain response of the jointed media have been formulated. A numerical incremental solution scheme to these equations has been developed. It has been implemented into the finite element code JAC as an additional material model. Several sample problems have been solved for demonstration purposes. Interpretation and discussion of these results are presented.
