The notion of partial plans has existed ever since the early days of planning research. However, plans can be partial in many different ways, and for many different reasons. This paper presents a characterization of partial plans and discusses the use of partial plans in incremental planning under computational and informational constraints. A heuristic for guiding the generation of plausible p...

background: organic acids refer to a family of compounds that are intermediates in a variety of metabolic pathways. many organic acids are present in urine from clinically normal individuals. elevated levels of urine organic acids cause to the organic acidurias, disorders in which some metabolic pathways in organic acid metabolism are blocked. the present work identified major and minor urinary...

The diversity of immunoglobulin (Ig) functions may be explained by the peculiar structure of these flexible molecules. Heavy and light Ig chains are composed from compact stable immunoglobulin folds (IgF), or domains belonging to a large protein super family. Proteins composed from IgF have been found in various representatives of animal kingdom even those appeared during the very early stages ...

In this note we settle a question posed by Hobby and McKenzie in [2] on the nature of locally finite equational classes which satisfy some nontrivial congruence identity. We settle problem #14 from [2] by exhibiting a locally finite equational class V which omits types 1 and 5 and which satisfies some non-trivial congruence identity, but which contains a finite algebra having a type 4 minimal s...

Introduction The word brachydactyly is used to describe the hands and feet with shortened digits (brachy, meaning “short,” and daktylos, meaning “digit”) [1]. The digits themselves may be shorter than normal or they may appear small because of shortening of metacarpal and metatarsal bones in the hands or feet [1]. Most of the patients with brachydactyly do not require any specific treatment. Wh...

A collection of n distinct hyperplanes Li = {li = 0} ⊂ P , the (n − 1)-dimensional projective space over an algebraically closed field of characteristic not equal to 2, is a polar simplex of a smooth quadric Q = {q = 0}, if each Li is the polar hyperplane of the point pi = ⋂ j 6=i Lj , equivalently, if q = l 2 1 + . . .+ l 2 n for suitable choices of the linear forms li. In this paper we study ...

Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining yield and improving flour quality. A field experiment was conducted to examine the responses of three spring wheat varieties in pure variety and in variety mixtures under continuous cropping in Northeast China. Three modern spring wheat varieties, along with a three-variety mixture and a t...
