Silicosis is the most common occupational lung disease worldwide. It leads to respiratory impairment and may have associated infections that decrease pulmonary function. We describe the case of a 55-year-old man with chronic silicosis who presented with hemoptysis and a cavitated conglomerate mass. The final diagnosis was silicotuberculosis.

The first bent-core molecules comprising 4-iodoresorcinol as the central core unit and incorporating azobenzene units have been synthesized. A new type of dark conglomerate phase (DC phase) is observed, which remains over a wide temperature range down to room temperature without crystallization.

The racemic title compound, C(24)H(20)N(2), gives spontaneous resolution with the formation of conglomerate crystals in the space group P2(1)2(1)2(1) when crystallized from ethyl acetate. The twisted mol-ecules pack in parallel regions (ab plane) which then form a herringbone pattern along c.

In the pair of helical conformational polymorphs of the coordination polymer {[AgL](CF3SO3)}infinity(L=2-pyridinyl-3-pyridinylmethanone), the 2(1) helices of opposite chirality in one supramolecular isomer are stacked alternately to form a racemate, while the 4(1) helices in the other are assembled homochirally by inter-chain argentophilic interaction to generate a conglomerate.

We demonstrate that limited market participation can arise endogenously in the presence of model uncertainty. Our model generates novel predictions on the relation between limited market participation, the equity premium, and the diversification discount. When the dispersion in investors’ model uncertainty is small, full market participation prevails in equilibrium. In this case, the equity pre...

This paper examines the problem of relative attitude observability for formations of three, four and five vehicle formations. The analysis is rooted in within the principles of maximum likelihood estimation insomuch as the metric for observability is the resulting Fisher information matrix for the small attitude errors. For formations of three and four vehicles it is shown that the relative att...

Simulating fluid flow in geological formations requires mesh generation, lithology mapping to the cells, and computing geometric properties such as normal vectors and volume of cells. The purpose of this research work is to compute and process the geometrical information required for performing numerical simulations in geological formations. We present algebraic techniques, named Transfinite In...

A thin (3–25 cm), persistent conglomerate-sandstone unit occurs at the base of the transgressive systems tract of an Upper Pennsylvanian cyclothem below a transgressive limestone in outcrop and subsurface in SE Kansas and NE Oklahoma. It has an erosional base and a sharp top, and is composed of calcitic clasts, some shell fragments and quartz sand, and rare coal fragments. Clasts are rounded, e...

OBJECTIVES/HYPOTHESIS Knowledge of histopathological factors, such as perineural invasion (PNI), extracapsular spread (ECS), angiolymphatic vessel invasion, and conglomerate lymph nodes, in patients with head and neck squamous cell carcinoma is important for appropriate treatment decisions. Given the availability of aggressive therapeutic options with known side effects and burdens for the pati...

A rigorous control technique for such an agent-based robotic system may encounter problems of singularity, parameter sensitivity and inter-robot collision. Our proposed approach focuses on the enhancement of robustness as well as collision-free establishment of formations even in the case of singul...
