the selection of a growing medium is one of the most important decisions in the culture of hydroponic crops. in order to select a suitable medium for hydroponic cucumber (cucumis sativus l. cv. negin), an experiment was carried out on growing media containing different particle sizes of perlite and organic substrates in a run-to-waste system in a greenhouse experiment. the growing media tested ...

We studied nine solid and two liquid media for their suitability to select Aeromonas and Plesiomonas spp. from human stools, using artificially contaminated samples as well as 254 samples from outpatients with and without diarrhea. Media with optimal sensitivity and specificity for Aeromonas spp. were alkaline peptone-water, Trypticase soy broth with ampicillin, inositol-brilliant green-bile sa...

Research indicates employers use social media, such as Facebook and LinkedIn, to make decision regarding would-be employees. A scarce amount of academic research specifically examines the decision-making processes employers use when using social media to select the best job applicant for the job. This study focuses on how social media impacts hiring processes, investigating the impact of politi...

Feature selection is widely used in preparing highdimensional data for effective data mining. Attributevalue data in traditional feature selection differs from social media data, although both can be large-scale. Social media data is inherently not independent and identically distributed (i.i.d.), but linked. Furthermore, there is a lot of noise. The quality of social media data can vary drasti...

In adaptive HTTP streaming model, the HTTP server stores multiple representations of media content, encoded at different rates. It is the function of a streaming client to select and retrieve segments of appropriate representations to enable continuous media playback under varying network conditions. In this paper we describe design of a control mechanism enabling such a selection and retrieval...

Migration of neurons is crucial for brain development. Equally essential to this developmental process is the specific transport of proteins within the neuron for axonal and dendritic specification. This Neurobiology Select highlights new findings that shed light on the mechanisms regulating both the movement of proteins within neurons and the movement of neuronal cells themselves within the de...

The explosive popularity of social media produces mountains of high-dimensional data and the nature of social media also determines that its data is often unlabelled, noisy and partial, presenting new challenges to feature selection. Social media data can be represented by heterogeneous feature spaces in the form of multiple views. In general, multiple views can be complementary and, when used ...

Semen samples collected from 28 male partners of infertile couples were divided into three equal aliquots and prepared with three selected media, such as PureSperm (Nidacon, Gothenburg, Sweden), Sil-Select Plus (Fertipro, Beernem, Belgium) and SpermGrad (Vitrolife, Gothenburg, Sweden). The differences in mean percentages of semen parameters were assessed by repeated measures analysis. Correlati...

Expression of the Bacillus subtilis or Bacillus amyloliquefaciens sacB gene in the presence of sucrose is lethal for a variety of bacteria. Sucrose-induced lethality can be used to select for inactivation of sacB by insertion of heterologous DNA in sensitive bacteria. This procedure has not been applicable to B. subtilis heretofore because expression of wild-type sacB is not detrimental to B. s...
