    Objectives: This study investigated parental attitudes towards psychotropic drugs for children's mental disorders. Methods: A questionnaire was distributed to parents of children attending a child psychiatry clinic at a tertiary hospital in Muscat, Oman. Similarly, in a small proportion, other caregivers filled out the questionnaire in case the child attended with them. The questionnaire comprised questions regarding parents' opinions, and attitudes about psychotropic medications use. The logistic regression model was used to identify the risk factors associated with parents who prefer to consult a folk healer (FH) for children with mental disorders. Results: A total of 299 parents agreed to participate in the study. The majority of them (81.6%, n=244) agreed that they would give their child psychotropic medications if necessary, but 25.4% of them (n=76) would consult a FH before consulting a psychiatrist if their child experienced psychiatric symptoms. Married parents were 14 times (OR=14.5, p=0.011) more likely to consult a FH than were separated or divorced parents. Caregivers with a monthly income below 500 OMR and between 500-1,000 OMR were two times (OR=2.5, p=0.016) and three times (OR=3.2, p<.001), respectively, more likely to consult a FH than those with a monthly income of more than 1,000 OMR. Parents who disagreed with giving psychotropic medications to their children were three times (OR=3.7, p<.001) more likely to consult a FH than were parents who agreed to give psychotropic medications to their children if necessary. Conclusion: Most parents agreed to give their children psychotropic medications if it were deemed necessary. However, a sizeable proportion of parents and caregivers preferred to consult a FH before accessing mental health services. Keywords: Parents; Children; Attitudes; Psychotropic Drugs; Oma

    Potential Solutions for the Short to Medium-Term Natural Gas Shortage Issues of Europe: What Can Qatar Do?

    European countries are required to look for alternative gas suppliers to deliver energy security for Europe. Qatar has been proposed to be an alternative gas supplier; however, there are problems that limit Qatar from exporting more gas to Europe, namely: the limited LNG quantities available for export, the long-term fixed contracting strategy, and the lack of room to receive additional gas in European LNG terminals. As these problems are critical and limit Qatar from exporting more gas to Europe, this research aims to propose potential solutions to overcome them. The results show that to solve the issue of the limited LNG quantities available for export, Qatar can produce electricity from renewable sources and export the gas consumed for power production, and can produce renewable natural gas (RNG) from green hydrogen and captured carbon dioxide. Two BCM of natural gas can be exported if 15% of the electricity required is produced from renewables in Qatar. In addition, 0.45 BCM of RNG can be exported if Qatar uses its natural resources to produce 5000 MW of renewable power. Redirecting contracts coming to an end and increasing dependence on spot markets can resolve the issue of a long-term fixed contracting strategy. Finally, using floating import terminals may alleviate the problem of European LNG terminals running out of room to receive more gas

    Thermodynamic analysis of theoretical dolomite formation from seawater and captured carbon dioxide

    In this study, an integrated system is proposed to form dolomite chemically from seawater and carbon dioxide. The system contains three main chemical processes: formation of magnesium hydroxide and calcium hydroxide, the reaction of magnesium hydroxide and calcium hydroxide with carbon dioxide, and the formation of dolomite. Based on the fundamental thermodynamic laws, energy and exergy analyses, and performance assessment of the proposed system is carried out. Furthermore, the effects of varying temperatures of each process on various energy and exergy efficiencies are assessed through parametric studies. The results show that formation of dolomite is favorable at temperature ranges of 313–470 K based on the thermodynamic study. The exergy efficiency of dolomite formation is found to be about 23.8% and the results reveal that the dolomite formation process has the specific exergy destruction value of 29.6 kJ/mol among other sub-processes. The results suggest that the proposed system may provide enhanced options for low-temperature dolomite formation using seawater and captured carbon dioxide once the reaction kinetics is favored.Other Information Published in: SN Applied Sciences License: https://creativecommons.org/licenses/by/4.0See article on publisher's website: http://dx.doi.org/10.1007/s42452-019-1313-7</p

    Evaluating LNG Supply Chain Resilience Using SWOT Analysis: The Case of Qatar

    No full text
    The demand for liquefied natural gas (LNG) as an energy commodity is increasing, although its respective supply chain is subjected to risks, uncertainties, and disturbances. An analysis of experiences from the global LNG supply chain highlights many of these risks. As such, there is an incumbent need to develop resilient LNG supply chains. In this study, the risks associated with the LNG supply chain are categorized into four dimensions: Political and regulatory, safety and security, environmental effects, and reliability of new technologies. A SWOT method is then implemented to identify strengths, weaknesses, opportunities, and threats within the LNG supply chain, where the LNG supply chain of Qatar is considered as a case study. Relevant strategies are then recommended using a SWOT matrix to maximize strengths and opportunities, while avoiding or minimizing weaknesses and threats within the LNG supply chain. Finally, major parameters to be considered to develop a resilient LNG management model are listed based on the level of priority from LNG producer and receiver perspectives. Thus, as part of creating a robust LNG supply chain, decision-makers and stakeholders are urged to use the learnings from the SWOT analysis and experiences from LNG supply chain management

    Genome-wide SNP analyses reveal high gene flow and signatures of local adaptation among the scalloped spiny lobster (Panulirus homarus) along the Omani coastline

    Background: The scalloped spiny lobster (Panulirus homarus) is a popular seafood commodity worldwide and an important export item from Oman. Annual catches in commercial fisheries are in serious decline, which has resulted in calls for the development of an integrated stock management approach. In Oman, the scalloped spiny lobster is currently treated as a single management unit (MU) or stock and there is an absence of information on the genetic population structure of the species that can inform management decisions, particularly at a fine-scale level. This work is the first to identify genome-wide single nucleotide polymorphisms (SNPs) for P. homarus using Diversity Arrays Technology sequencing (DArT-seq) and to elucidate any stock structure in the species. Results: After stringent filtering, 7988 high utility SNPs were discovered and used to assess the genetic diversity, connectivity and structure of P. homarus populations from Al Ashkharah, Masirah Island, Duqm, Ras Madrakah, Haitam, Ashuwaymiyah, Mirbat and Dhalkut landing sites. Pairwise F-ST estimates revealed low differentiation among populations (pairwise F-ST range = - 0.0008 - 0.0021). Analysis of genetic variation using putatively directional F-ST outliers (504 SNPs) revealed higher and significant pairwise differentiation (p < 0.01) for all locations, with Ashuwaymiyah being the most diverged population (Ashuwaymiyah pairwise FST range = 0.0288-0.0736). Analysis of population structure using Discriminant Analysis of Principal Components (DAPC) revealed a broad admixture among P. homarus, however, Ashuwaymiyah stock appeared to be potentially under local adaptive pressures. Fine scale analysis using Netview R provided further support for the general admixture of P. homarus. Conclusions: Findings here suggested that stocks of P. homarus along the Omani coastline are admixed. Yet, fishery managers need to treat the lobster stock from Ashuwaymiyah with caution as it might be subject to local adaptive pressures. We emphasize further study with larger number of samples to confirm the genetic status of the Ashuwaymiyah stock. The approach utilised in this study has high transferability in conservation and management of other marine stocks with similar biological and ecological attributes
