The aim of this study was to determine the effect botanical biopesticide extracts and concentrations on soil termite mortality Coptotermes curvignathus, Holmgren. This research an experimental using a fully randomized design (CRD) consisting 2 3-level treatments that were repeated three times. Treatment type levels, namely are A1 (papaya leaf), A2 (soursop A3 (lemongrass leaf). In comparison, c...

The concept of semicopula plays a fundamental role in the definition of a universal integral. We present an extension of semicopula to the case of symmetric interval [−1,1]. We call this extension bipolar semicopula. The last definition can be used to obtain a simplified definition of the bipolar universal integral. Moreover bipolar semicopulas allow for extension of theory of copulas to the in...

Abiotic global change drivers affect ecosystem structure and function, but how they interact with biotic factors such as invasive plants is understudied. Such interactions may be additive, synergistic, or offsetting, and difficult to predict. We present methods to test the individual and interactive effects of drought and plant invasion on native ecosystems. We coupled a factorial common garden...

echis carinatus (saw-scale viper) is one of the most venomous snakes in asia and some parts of the africa with deadly hemotoxic venom. it has been reported that suramin, an antitrypansomiasis drug, can inhibits the toxic effects of some snake venoms. this study was conducted to evaluate the antagonistic effects of suramin against the venom of the iranian snake echis carinatus. adult albino mice...

Introduction. The purpose of this article is to introduce to information science in a coherent fashion the core premises of contemporary practice theory, and thus to engage the information research community in further debate and discussion. Method. Contemporary practice-based approaches are summarised in an ensemble of five core premises by means of a broad conceptual analysis of the relevant ...

Received 12 September 2003 Accepted 10 October 2003 Hepatitis B virus (HBV) X antigen (HBxAg) may contribute to the development of hepatocellular carcinoma (HCC) by activation of signalling pathways such as NF-kB. To identify NF-kB target genes differentially expressed in HBxAg-positive compared to -negative cells, HepG2 cells consistently expressing HBxAg (HepG2X cells) were stably transfected...

This study aims at specifying cultural words in teaching Turkish as a foreign language according to their proficiency levels (A1/2, B1/2, and C1/2) analyzing the difference between of these terms frequency. For this purpose, corpus 112.350 tokens total has been created based on written oral texts. In corpus, nouns verbs first 2000 frequency have compared with most common words, that are not mar...

Restoration of wet prairie in the central midwestern United States should include Prairie cordgrass (Spartina pectinata), but historic densities of this once dominant species are not easily achieved. Spartina pectinata was transplanted into a former agricultural field in three planting strategies: 20 small plugs, 4 medium-sized plugs, and a single large plug, with each treatment area totaling 0...

Autoantibodies directed against spliceosomal heterogeneous nuclear ribonucleoproteins (hnRNPs) are a typical feature of rheumatoid arthritis, systemic lupus erythematosus, and mixed-connective tissue disease. With the aim of investigating a potential pathogenic role of these Abs, we have studied the Ab response to A2/B1 hnRNPs in different murine models of lupus. The specificity of anti-A2/B1 A...

Following [2], we say a family, H , of subsets of a n-element set is cancellative if A∪B = A∪C implies B = C when A,B,C ∈ H . We show how to construct cancellative families of sets with c2 elements. This improves the previous best bound c2 and falsifies conjectures of Erdös and Katona [3] and Bollobas [1]. AMS Subject Classification. 05C65 We will look at families of subsets of a n-set with the...
