Introduction . Keywords, reflecting the main content of article, play an extremely important role in search for scientific papers databases. Together with title and abstract, keywords provide primary information about study. Selecting extracting effective is a time-consuming process, so its optimization requires further studying. Purpose. The article aimed at acquainting authors journal methods...

Acta Academica is an accredited, open access South African journal dedicated to scholarship in the humanities. The publishes independently refereed research articles It promotes perspectives of critical social theory and engagements with postcolonial post-developmental debates special references (Southern) Africa. thereby support scholarly work that examines how humanities twenty-first century ...

A new layout of the U-shaped automated terminal is more convenient to connect between and railway. In this study, a sort cluster scheduling method for multiple equipment yard railway proposed. The innovation points are as follows: (1) Considering that rail gantry crane (RGC), intelligent guided vehicle (IGV), double cantilever (DCRC) usually work in groups, they grouped cluster-scheduled. (2) h...

A capability to determine the availability of nitrogen in organic amendments is necessary to ensure that such materials will provide sufficient nitrogen to the growing crop and cause minimal environmental degradation. Greenhouse bioassays were used to evaluate N availability of organic by-products, including several employed in the field study of this research. Tall fescue was grown in greenhou...

OBJECTIVE We investigated the effectiveness of a theoretically motivated intervention at reducing procedural errors in train yard operations, where making these errors could be costly or life-threatening. BACKGROUND A widespread and persistent memory error that people commit on a daily basis is the postcompletion error (PCE), that is, forgetting to complete the final step of a procedural task...

Many cities in the Global South are structurally different from Northern, particularly American, on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them terms a standard vocabulary risks imposing an inappropriate way seeing. We need that is able to accommodate their experience. This special issue contributes work building vocabulary. select five keywords soc...

We propose a dynamic model for optimizing the ows of atcars that considers explicitly the broad range of complex constraints that govern the assignment of trailers and containers to a atcar. The problem is formulated as a logistics queueing network which can handle a wide range of equipment types and complex operating rules. The complexity of the problem prevents a practical implementation of a...

Fix an odd integer d ≥ 1 and let Fd ⊂ R2 denote the real Fermat curve defined by the equation xd + yd = 1. Here we prove that Fd has the following property: Let X ⊆ Rn be any real algebraic variety. Then there exists a “one-parameter isotopic Nash modification” X̃t of X such that X̃0 = X and each real algebraic variety X̃t, t = 0 may be biregularly embedded into (Fd).
