We present our investigation on the effect of warps on the extraction of rotation curves in edge-on galaxies. The method to derive the rotation curve from the position-velocity diagram in warped edge-on systems yields underestimated velocities, and the tilted-ring model is not reliable in highly inclined, poorly resolved galaxies. In a warped system the kinematical major axis is different from ...

Transitive closure operation is one of the most useful new operations in deductive database systems. When it is added to conventional relational database systems, most practical problems with recursion can be coped with. Therefore, efficient processing of transitive closure is an important task in deductive database systems. Transitive closure operation can be divided into total closure and que...

Our aim was to optimize a SOA control system by evolving the architecture of the service component that transforms system models into task trees, which are then executed by the runtime library called the Task Tree Executor, TTE. In the paper we present the two novel TTE architectures that evolved from the previous TTE architecture and introduced finer grained parallelism. The novel architecture...

Inhibitors of CK2 kinase inhibit cell proliferation and induce apoptosis in numerous cancer cell lines. Due to these properties, they are considered potentially useful in anticancer therapy. In this study, we show that the exact effect of the specific CK2 inhibitor TBB on PC-3 human prostate cancer cell viability depends on the time schedule of ad...

Python is popular among numeric communities that value it for easy to use number crunching modules like [NumPy], [SciPy], [Dask], [Numba], and many others. These modules often use multi-threading for efficient multi-core parallelism in order to utilize all the available CPU cores. Nevertheless, their threads can interfere with each other leading to overhead and inefficiency if used together in ...

Essential oils (EOs) from Cymbopogon citratus (CC), Eucalyptus citriodora (EC), Eucalyptus camaldulensis (ED), and Citrus sinensis (CS) were obtained by hydrodistillation process. The EOs were evaluated in vitro for activity against Trypanosoma brucei brucei (Tbb) and Trypanosoma evansi (T. evansi). The EOs were found to possess antitrypanosomal activity in vitro in a dose-dependent pattern in ...

In Wireless Sensor Networks, recent studies reveal mobility of the sink nodes as a solution for collecting the data from the sensor nodes. The mobile element acts as a mechanical carrier for collecting the data from the sensor nodes. Each sensor node is assigned a buffer for accumulating the sensed data and data loss occurs if the buffer overflows. Therefore, scheduling the mobile element such ...

Riparian buffers can influence water quality in downstream lakes or rivers by buffering non-point source pollution in upstream agricultural fields. With increasing nitrogen (N) pollution in small agricultural watersheds, a major function of riparian buffers is to retain N in the soil. A series of field experiments were conducted to monitor pollutant transport in riparian buffers of small waters...

Fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) and transbronchial biopsy (TBB) was performed in 40 patients suspected to have pulmonary tuberculosis, in whom chest roentgenogram revealed minimal infiltration and sputum smears were negative for acid-fast bacilli. Bronchoscopic procedures provided overall diagnostic yields in 47.5% (19/40) of patients. The diagnostic yield of overall b...
