Understanding the drivers of diversity patterns in ecological communities remains a major challenge ecology. Moreover, few studies have considered invertebrate or subterranean and little is known about which factors are responsible for structuring arthropod caves. In this study we: assessed abundance, richness, composition from eight caves located Banat Mehedinti region, Romania; determined whe...

Salah satu kemampuan dasar wahana terbang type fixedwing adalah dapat lepas landas pada area yang terbatas, cepat mencapai lokasi diinginkan secara aman, akurat lintasan dan kembali ke base untuk mendarat dengan selamat. Misi khusus seperti pertolongan pertahanan membutuhkan mampu akurat, tetapi performa tersebut juga konsumsi energi besar. Untuk mendapatkan cepat, namun efisien, didesain model...

this paper deals with the basic notions of k-tautimmersions . these notions come from two special cases; that is, tight and taut immersions. tight and taut based on high and distance functions respectively and their basic notions are normal bundle, endpoint map, focal point, critical normal. we generalize hight and distance functions to cylindrical function and define basic notions of k-taut im...

Superconductivity is described by the well-known Bardeen-Cooper-Schrieffer (BCS) theory, which is a symmetry breaking approximation. Color superconductivity shows up in extremely high density matter and temperature, which is here investigated and compared to the other end of the scale of low energy/temperature of organic superconductors. An approach to color superconductivity conciliating the B...

Educators are encouraged to develop their technology integration abilities as information and communication (ICT) advances in the field of education. This has ramifications for school curriculum, which must be able adapt changing circumstances order satisfy educational demands pupils during industrial revolution. 4.0. Training on construction digital learning materials utilizing whiteboard anim...

In the current study, this way was adopted numerically in order to optimize performance of a HEC through use extended solid sections form 'W' (W-baffles: WBs). All limit conditions channel have been defined, with all thermo-physical properties HTF (heat transfer fluid) used. The FVM (Finite-Volume-Method) has some necessary numerical schemes give solution, which allows us visualize dynamically ...

4 Allee effects and parasitism are common biological phenomena observed in nature, which are believed to have significant impacts in ecological conservation programs. In this article, we investigate the population dynamics of host-parasitoid systems with Allee effects induced by predation satiation in host to study the effects of Allee effects and parasitism as well as the timing of parasite’s ...

We say that a graph G = (V,E) on n vertices is a β-expander for some constant β > 0 if every U ⊆ V of cardinality |U | ≤ n 2 satisfies |NG(U)| ≥ β|U | where NG(U) denotes the neighborhood of U . We explore the process of uniformly at random deleting vertices of a β-expander with probability n for some constant α > 0. Our main result implies that as n tends to infinity, the deletion process perf...
