Abstract. The paper examines the process of creating and publishing an Arabic Linked Drug Dataset based on open drug datasets from selected Arabic countries and discusses quality issues considered in the linked data lifecycle when establishing a semantic Data Lake in the pharmaceutical domain. Through representation of the data in an open machine-readable format, the approach provides an optimum solution for information and dissemination of data and for building specialized applications. Authors contribute to opening the drug datasets from Arabic countries, interlinking the data with diverse repositories such as DrugBank, and DBpedia, and publishing it in a standard open manner that allows further integration and building different business services on top of the integrated data. This paper showcases how drug industry can take full advantage of the emerging trends for building competitive advantages. However, as is elaborated in this paper, better understanding of the specifics of the Arabic language is needed in order to extend the usage of linked data technologies in Arabic companies.

Libya is a lower middle-income country with no national surveillance system for hospital-acquired infections (HAIs). We assessed the prevalence of hospital-acquired infections and antimicrobial use in adult intensive care units (ICUs) in Libya. Objective: Evaluate drug resistance of bacteria isolated from equipment placed close to patients in an Intensive Care Unit of a Central hospital in Gharian.

In this paper, of primary interest is to synthesis 8-(1H-indol-3-ylazo)-naphthalene-2-sulfonic acid (INSA) and to evaluate the main parameters of Au/INSA/n-Si/Al diode in dark and under illumination. Different techniques are used for interpreting the proposed INSA chemical structure. The dark current-voltage measurements were achieved in the temperature range of 293−413 K. It is noticed that INSA films modify the interfacial barrier height of classical Au/n-Si junction. At low applied voltages, the I–V relation shows exponential behavior. The values ideality factor, n, and the barrier height, φ, are improved by heating. The abnormal trend of n and φ is discussed, and a homogenous barrier height of 1.45 eV is evaluated. The series resistance is also calculated using Norde's function and it changes inversely with temperature. The space charge limited current ruled with exponential trap distribution dominates at relatively high potentials, trap concentration and carriers mobility are extracted. The reverse current of the diode has illumination intensity dependence with a good photosensitivity indicating that the device is promising for photodiode applications.

Linked Open Data illustrates the concept that provides an optimum solution for information and dissemination of data, through the representation of the

data in an open machine readable format and to interlink it from diverse repositories to enable diverse usage scenarios for both humans and machines.

The pharmaceutical/drug industry was among the first that validated the applicability of the approach for interlinking and publishing open linked data. Yet, open issues arose clearly when trying to apply the approach to datasets coded in languages other than English, for instance, in Arabic languages. Author’s objective is to examine in detail the requirements specification process for building Linked Data application taking into consideration the possibility of reusing recently published datasets and tools. Main conclusions derived from this study are that making drug datasets accessible and publish it in an open manner in linkable format adds great value by integration to other notable datasets. Author’s main contribution is the enhancement of Arabic knowledge graph based on drug data from selected Arabic countries and the novel methodology for building Linked Data applications.

Wireworm has become a major problem causing extensive crop loss in many potato production areas in Canada. Wireworm control methods includes the use of chemical pesticides. However, pesticides can affect human health and the environment, and their use has consequently been questioned and prohibited in many countries. Therefore, the use of environmentally friendly plant protection techniques, including crop rotation as an alternative to chemical control measures have been promoted to minimize crop damage. In that context, buckwheat is used as a rotation crop to mitigate wireworm damage in potatoes. But so far, less is known about how buckwheat contributes to mitigate disease. This study was designed in a context of integrated pest management, with primary objectives to:(1) determine the microbial diversity in the buckwheat rhizosphere in comparison with other rotation crops; and (2) determine the correlation between the buckwheat rhizosphere microbiome structure and wireworm density. To achieve these objectives, 16S rRNA metagenomic sequencing was performed to determine the microbial diversity in bulk and rhizosphere soils of buckwheat and barley grown at two locations during two growing seasons. A pilot wireworm trapping study was also performed to assess the wireworm population following buckwheat and barley as rotation crops. The study identified 27 phyla in the two crops of which Proteobacteria, Bacteroidetes, Actinobacteria were the most abundant and species identification was confidently achieved in 7 phyla including Proteobacteria, Actinobacteria, Acidobacteria, Bacteroidetes, Firmicutes, Deinococcus-Thermus and Crenarchaeota. Interestingly, Methylophilus flavus, Saccharopolyspora tripterygii and Deinococcus yunweiensis were three operational taxonomic units (OTUs) found at the species level to be unique to the buckwheat rhizosphere soil at both locations and purported as non-pathogenic entophytic bacteria and beneficial for sustainable agriculture. Moreover, after two years, a reduction in wireworm density was observed in both crops although, the direct link associating the reduced wireworm density and the observed microbial diversity and the operating mechanisms in each crop remain to be elucidated. Taken together, changes were observed in the soil microbial communities associated with specific rotation crops and a reduction in wireworm density was correlatively observed. Thus, our study showed that the root system of buckwheat influences the structure of the microbiome in the rhizosphere as .hypothesized
