Karst collapse columns, as a potential water passageway for mine water inrush, are always considered a critical problem for the development of deep mining techniques. This study aims to identify the mixing process of groundwater deriving two different limestone karst-fissure aquifer systems. Based on analysis of mining groundwater hydrogeochemical properties, hydraulic connection between the ka...

If F is a geometry for this rank 3 diagram and F' is its shadow geometry with respect to the central node of the diagram, then f satisfies the Intersection Property (IP), it belongs to the following diagram where L and L* denote the classes of linear spaces and dual linear spaces, respectively. According to a well established habit, we only consider residually connected and firm geometries. Tha...

It is known that, in vitro, PIPER (N,N'-bis [2-(1-piperidino)ethyl]-3,4,9,10-tetracarboxylic diimide) induces the formation of the Hoogsteen quadruplex structure in telomere DNA, thus inhibiting the polymerisation of telomeric repeats. Since the action of PIPER in vivo has been scarcely investigated, this study was addressed to gain some insight into the effects of this drug on cultured HeLa ce...

Abstract The chief source of the oilfield scale is mixing incompatible waters. This study demonstrated that reservoir Mishrif formation (Halfaya oilfield) with six types injection water sources, including Tigris River water, producing formation, Gulf seawater, Marshes Middle Kirkuk and Main Outfall Drain (AL-Masab AL-Aam Channel), leads to salt crusts cause reduction rock permeability. Accordin...

Abstract Wetlands deliver many ecosystem services but are under continuous threat due to various anthropogenic activities. The present study has been carried out examine the suitability of Kusheshwar-Asthan wetland's water for agriculture. A total 57 samples were analyzed quality parameters like electrical conductivity, pH, temperature, dissolved oxygen (DO), major cations (Ca2+, Mg2+, Na+, K+)...

Human body models (HBMs) have the potential to provide significant insights into the pediatric response to impact. This study describes a scalable/posable approach to perform child accident reconstructions using the Position and Personalize Advanced Human Body Models for Injury Prediction (PIPER) scalable child HBM of different ages and in different positions obtained by the PIPER tool. Overall...

In Flora Costaricensis, William Burger of the Field Museum in Chicago considered eight of the Piper species that occur in Costa Rica to make up the P. obliquum complex, and six additional species to be closely allied to it (Fig. 9.1; Burger 1971). Piper calcariformis, an additional species assignable to the P. obliquum complex, was later described by Tebbs (1989). Although Burger did not apply ...

The genus Piper is an important component of tropical forests worldwide. Many Piper species have been reported as self-compatible (Figueiredo & Sazima 2000), and many have the ability to reproduce asexually, forming clonal aggregations (Grieg 1993). Furthermore, the main dispersers of Piper (bats) transport whole infructescences to feeding roosts (Fleming & Heithaus 1981), tending to disperse c...
