the relationships between topography and crop yield. Graveel et al. (1989) observed that corn yields were The purpose of this study was to relate the temporal and spatial more variable on steep slopes but found no significant variability of corn (Zea mays L.) grain yield on a Typic Fragiochrept soil on a hillslope to soil properties and topographic features. Corn differences for degree of slope...

The new species is a member of an apparently monophyletic group within the genus that includes R. flexile, R. walga, R. himanturi, R. burgeri, R. euzeti, R. hawaiiensis, R. urobatidium, R. paratrygoni, R. ditesticulum, R. tetralobatum, R. margaritense, R. biorchidum, and R. spinicephalum. All of these species have bothridia with medial longitudinal septa, a constriction at mid-bothridium, and, ...

In the present work, the author determines some coefficient bounds for functions in a new class of analytic and bi-univalent functions, which are introduced by using of polylogarithmic functions. The presented results in this paper one the generalization of the recent works of Srivastava et al. [26], Frasin and Aouf [13] and Siregar and Darus [25].

Haptic interfaces are devices that allow human-machine interaction through force and touch. Combined haptic and visual interfaces have been around for decades. Yet, despite an enormous increase in research activity in the last few years, the science of haptics is still a technology in its infancy. The majority of commercially available haptic devices operate based on a principle of point intera...

2000, Simpson et al., 2001). A more comprehensive model proposes fl owering as a part of shoot maturation process (Schultz and Haughn, 1991). Current research aims at clarifying the relationship among the various genes and group them into different, yet overlapping, signaling pathways, and deciphering the molecular mechanism of how the repressors work, e.g., what genes they repress, and how the...

β-catenin was originally identified complexed with the cell adhesion molecule (CAM) E-cadherin (Vestweber and Kemler, 1984; Ozawa et al., 1989; Nagafuchi and Takeichi, 1989). Subsequently, β-catenin was found to bind directly to the cytoplasmic domain of E-cadherin and to α-catenin, linking this adhesion complex to the actin cytoskeleton (Aberle et al., 1994; Aberle et al., 1996a; Hülsken et al...

This paper contrasts two types of educational tools: a route-type series of so-called statistical minitools (Cobb et al., 1997) and a landscape-type construction tool, named Tinkerplots (Konold & Miller, 2001). The design of the minitools is based on a hypothetical learning trajectory (Simon, 1995). Tinkerplots is being designed in collaboration with five mathematics curricula and is open to di...

Importance of Beef Tenderness Beef palatability is affected by many factors and tenderness is cited as one of the most important. Consumers are willing to pay a premium for a guaranteed tender product with the potential to increase the value of the middle meats over $60 per carcass (Miller et al., 2001). Consequently, the meat industry is in a continual search for methods to improve the tendern...
