Winemakers use technical enzymes to assist with clarification, extraction, and other processes in winemaking. In some cases, enzyme mixes are found be ineffective for a variety of reasons. This study characterizes difficult-to-clarify juices from the Muscat family, examines effects pasteurization, classifies these based on cultivar, harvest date, geographical location, harvesting technique. add...

A connection graph represents resolvability in a set of clauses explicitly. The corresponding connection graph proof procedure has the deeciency that the graphs may grow, becoming impractical to handle. We present a novel proof procedure for condition graphs, which is a reenement of connection graphs. Our idea is to control the growth of the graph by recognizing tests in clauses and translating...

Gas chromatography-olfactometry-mass spectrometry (GC-O-MS) has been very useful in identifying aroma compounds from within the complex matrix of wine. Supplementary separation can be required to overcome co-elution volatiles or other sensory-directed chromatographic strategies are needed, including multidimensional chromatography and preparative fraction collection coupled GC. Studies investig...

A goal in insect–microbe ecology is to understand the mechanisms regulating species associations and mutualistic interactions. The spotted wing drosophila Drosophila suzukii develops ripening fruit, unlike other drosophilids that typically feed on overripe associated with yeast Hanseniaspora uvarum. We hypothesized D. H. uvarum engage niche construction leading a relation, facilitating exploita...

Laan in (Ph.D Thesis, Tartu. 1999) introduced the principal weak form of Condition $(P)$ as Condition $(PWP)$ and gave some characterization of monoids by this condition of their acts. In this paper first we introduce Condition (G-PWP), a generalization of Condition $(PWP)$ of acts over monoids and then will give a characterization of monoids when all right acts satisfy this condition. We also ...

In this paper we introduce condition (E?P) a generalization of Conditions (E?), (E) and (P) of acts over monoids and will give a classification of monoids by comparing this condition of their (Rees factor) acts with other properties. We give also a criterion of cyclic acts to satisfy Condition (E?P).

this paper is devoted to the study of products of classes of right $s$-posets possessing one of the flatness properties and preservation of such properties under products. specifically, we characterize a pomonoid $s$ over which its nonempty products as right $s$-posets satisfy some known flatness properties. generalizing this results, we investigate products of right $s$-posets satisfying condi...
