Though, in the literature, many heuristic approaches were developed in getting an initial solution, VAM (Vogel’s approximation method) is considered to be a better efficient heuristic approach since it often provides an optimal or near optimal solution to the transportation problem. In general, transportation problems involved in supply-chain management fields are unbalanced (total supply > tot...

The Vienna Abstract Machine (VAM) is an abstract machine which has been designed to eliminate some weaknesses of the Warren Abstract Machine (WAM). Diierent versions of the VAM are used for diierent purposes. The VAM 2P is well suited for interpretation, the VAM 1P is aimed for native code generation. The VAM 2P has been modiied to the VAM AI , a concept suited for abstract interpretation. Anal...

Soybean (Glycine max [L.] Merr.) plants were nodulated (Bradyrhizobium japonicum) and either inoculated with the vesicular-arbuscular mycorrhizal (VAM) fungus Glomus mosseae (Nicol. & Gerd.) Gerd. and Trappe or left uncolonized. All plants were grown unstressed for 21 days initially. After this period, some VAM and non-VAM plants were exposed to four 8-day drought cycles while others were kept ...

It has been noted previously that nutrient-stressed plants generally release more soluble carbohydrate in root exudates and consequently support more mycorrhizae than plants supplied with ample nutrients. Fertilization may select strains of vesicular-arbuscular mycorrhizal (VAM) fungi that are inferior mutualists if the same characteristics that make a VAM fungus successful in roots with a lowe...

Eucalyptus species are considered to have ectomycorrhizas (ECM), but many also have vesicular–arbuscular mycorrhizas (VAM) and their relative importance is unclear. Interactions between ECM and VAM fungi colonizing roots of Eucalyptus species were examined in a glasshouse experiment. This experiment investigated competition between these two types of fungi and compared benefits provided to Euca...

In mycorrhizal symbioses, susceptibility of a host plant to infection by fungi is influenced by environmental factors, especially the availability of soil phosphorus. This study describes morphological and biochemical details of interactions between a vesicular-arbuscular mycorrhizal (VAM) fungus and potato (Solanum tuberosum L. cv Russet Burbank) plants, with a particular focus on the physiolo...

In this study, silver nanoparticles (AgNPs) were synthesized by the citrate reduction process and, with the assistance of n-hydroxysuccinimide and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide, were successfully loaded with the macromolecular drug vancomycin (VAM) to form AgNP-VAM bioconjugates. The synthesized AgNPs, VAM, and AgNP-VAM conjugate were characterized by UV-visible spectroscopy, z...

Monoclonal antibodies (MAbs) against Pseudorabies virus (PrV) were obtained by the fusion of P3x-Ag8.653 myeloma and spleen cells from immunized BALB/c mice with a suspension of Pseudorabies (PrV) virus strains: MAVE (Morbus Aujeszk'y virus Ercegovac) and NS 257 (Novosadski virus strain). A total of 95 antibody-secreting hybridoma cells against the virus strain (MAVE and NS 257) of Pseudorabies...

The programming language Prolog has built-in predicates which enable the modiication of a program at runtime. This makes the global compilation of Pro-log programs a complex task. This paper presents an intermediate representation which enables fast incre-mental global compilation of Prolog. This intermediate representation is based on the Vienna Abstract Machine (VAM) with its two versions, th...
