    Abstract This study investigates the constitutional and conceptual underpinnings of Kuwait’s system of government. The Constitution of Kuwait, which was ratified in 1962, promulgated democracy as its government system; yet curiously, the Constitution lacked any actual explanation of the concept of democracy. Instead, it merely identified the system of government as ‘democratic’, with ‘the people of Kuwait’ as the source of all powers. To explain what Kuwaiti democracy and its government system truly involve, the study has traced its roots and origins: first, by shedding light on the ruling traditions since Kuwait emerged and flourished as a small city state in the seventeenth century. Second, by demonstrating how the Constitution and its Explanatory Memorandum explain Kuwait’s system of government. Third, by narrating the tale of the Constitution and its ratification in 1962 by the elected members of the Constituent Council. The study also focuses on the controversial history of the Islamic Sharia clause in the Arab world, reflected in the Minutes of Proceedings of both the Constituent Council and Constitution Committee. In addition, it highlights the evolution of representative councils, encompassing the 1921 Shura Council, the 1938 Legislative Council, and the 1961 Constituent Council; and applies David Held’s classical models of democracy to the theoretical model adopted by scholars of Kuwait constitutional law. Historical, constitutional and conceptual narratives on democracy lead the research to conclude that Kuwait’s political experience is rich and unique. In the early 1960s, Kuwait successfully withstood all regional challenges to become the first independent, democratic state in a region known for its autocratic regimes. Yet for over half a century since, it has never tackled the constitutional and conceptual shortcomings inherent in its adoption of a hybrid system. Accordingly, the study finds that the system of government in Kuwait is mixed; with its political system infused with rudimentary features of hereditary, representative, parliamentary and presidential systems, and profoundly influenced by its Arab-Islamic roots

    A modified route to unsymmetrically substituted triphenylenes, new functionalised derivatives and twins, and the smallest reported triphenylene mesogen

    We report the unexpected observation of columnar mesophase formation in a simple 2,7-dibromotetramethoxytriphenylene – by far the most lightly substituted discotic mesogen in this class. This derivative was prepared alongside the 3,6-dibromotriphenylene isomer to demonstrate an alternative, modified synthetic strategy that permits late-stage interchange of alkyl chain substituents. The new method is employed alongside the original route to deliver several new materials, including a conjugated ferrocene-triphenylene-ferrocene triad, a BODIPY-triphenylene-BODIPY triad and a new nematic twin linked through imine bridges

    Hypothalamo-pituitary axis and puberty

    Get PDF
    Puberty is a complex process that culminates in the acquisition of psychophysical maturity and reproductive capacity. This elaborate and fascinating process marks the end of childhood. Behind it lies a complex, genetically mediated neuroendocrine mechanism through which the gonads are activated thanks to the fine balance between central inhibitory and stimulating neuromodulators and hormones with both central and peripheral action. The onset of puberty involves the reactivation of the hypothalamic-pituitary-gonadal (HPG) axis, supported by the initial “kiss” between kisspeptin and the hypothalamic neurons that secrete GnRH (the GnRH “pulse generator”). This pulsatile production of GnRH is followed by a rise in LH and, consequently, in gonadal steroids. The onset of puberty varies naturally between individuals, and especially between males and females, in the latter of whom it is typically earlier. However, pathological variations, namely precocious and delayed puberty, are also possible. This article reviews the scientific literature on the physiological mechanisms of puberty and the main pathophysiological aspects of its onset

    Purpose: To assess the knowledge, attitude and magnitude of self-medication among medical students of Jazan University, Jazan, Saudi Arabia.Methods: A cross-sectional, self-administered questionnaire-based study was conducted among undergraduate medical students of Jazan University, Jazan, Saudi Arabia. A total of 300 students were selected by random sampling.Results: Self-medication practice was highly prevalent among the medical students, with 87 % reporting that they indulge in it. Self-medication was more prevalent among female students than male. Sedatives were the most common drugs used by students for self-medication (58 %). The most common reason adduced for self-medication practice was their belief that they have sufficient information, previous experience, and the experience of others, such as family members and colleagues, with regard to the drugs. A huge proportion (84.5 %) of the respondents agreed that selfmedication could be harmful and is associated with adverse effects, while 52.6 % stated that they would not advise other persons to indulge in self-medication.Conclusion: Self-medication is prevalent among third-year medical students of Jazan University in Saudi Arabia. Although the students exhibited sufficient awareness of self-medication, the findings highlight the need for intervention programmes regarding the practice of self-medication.Keywords: Self-medication, Prevalence, Awareness, Sedatives, Medical student

    The lipid composition of the seeds from two soft wheat varieties (Triticum aestivum, cv. Marchouche and Mahdia) were analyzed before and after accelerated aging. Eight days of accelerated aging resulted in a total inhibition of seed germinability as well as a decrease in their total and especially unsaturated fatty acid contents. Oleic and linoleic acid contents decreased particularly in the phosphatidylcholine of the seeds from both varieties. The proportion of polar lipids also decreased after aging as compared to neutral lipids: a 5.8% and 7.2% decrease in polar lipids was e observed in Mahdia and Marchouche cultivars, respectively. In the neutral lipids of the seeds from the Marchouche variety, the percentage of free fatty acids increased whereas the triacylglycerols decreased. After aging, the fatty acid compositions of all lipid classes were modified in the same manner as total fatty acid compositions. Among polar lipids, phospholipid proportions were particularly small, especially the phosphatidylcholine percentages with an 18.1% and 19.1% decrease in Mahdia and Marchouche varieties, respectively. In contrast, MGDG percentages increased, especially in the seeds from the Marchouche variety. A 15.5% increase was noticed when compared with seeds which were not aged. At the same time, the DGDG percentage showed a 16.6% decrease after accelerated aging of the seeds from the Marchouche variety. From these results we concluded that the lipid content decrease observed in seeds after accelerated aging could be linked to a loss in the germination and vigor of wheat seeds.La composición lipídica de semillas de dos variedades de trigo blando (Triticum aestivum, cv. Marchouche and Mahdia) fueron analizadas antes y después del envejecimiento acelerado. Ocho días de envejecimiento acelerado provoco una inhibición total de la geminabilidad, así como un descenso en el contenido total de ácidos grasos, en especial de los ácidos grasos insaturados. Los contenidos del ácido oleico y linoleico disminuyeron particularmente, en la fosfatidilcolina de las semillas de ambas variedades. La proporción de lípidos polares también decreció después del envejecimiento en comparación con los lípidos neutros: un descenso del 5.8% y 7.2% de los lípidos polares fueron observados en los cultivos de Mahdia y Marchouche, respectivamente. En los lípidos de las semillas de la variedad Marchouche, el porcentaje de ácidos grasos libres aumento, mientras que los triglicéridos decrecieron. Después del envejecimiento, la composición de los ácidos grasos de todas las clases de lípidos fue modificada de la misma manera que la composición de los ácidos grasos totales. Entre los lípidos polares, la proporción de fosfolípidos fue la que disminuyo principalmente, en especial el porcentaje de fosfatidilcolina: un 18.1% y 19.1% para las variedades Mahdia y Marchouche, respectivamente. Por otra parte, los porcentajes de MGDG aumentaron, en especial en las semillas de la variedad Marchouche: un 15.5% en comparación con las semillas no envejecidas. Al mismo tiempo, los porcentajes de DGDG mostraron un descenso del 16.6% después del envejecimiento acelerado de semillas de la variedad Marchouche. De todos estos resultados, se concluye que el descenso del contenido lipídico observado en semillas después del envejecimiento acelerado podría estar relacionado con una pérdida de germinación y de vigor de semillas de trigo

    Fuzzy integral for rule aggregation in fuzzy inference systems

    Get PDF
    The fuzzy inference system (FIS) has been tuned and re-vamped many times over and applied to numerous domains. New and improved techniques have been presented for fuzzification, implication, rule composition and defuzzification, leaving one key component relatively underrepresented, rule aggregation. Current FIS aggregation operators are relatively simple and have remained more-or-less unchanged over the years. For many problems, these simple aggregation operators produce intuitive, useful and meaningful results. However, there exists a wide class of problems for which quality aggregation requires non- additivity and exploitation of interactions between rules. Herein, we show how the fuzzy integral, a parametric non-linear aggregation operator, can be used to fill this gap. Specifically, recent advancements in extensions of the fuzzy integral to \unrestricted" fuzzy sets, i.e., subnormal and non- convex, makes this now possible. We explore the role of two extensions, the gFI and the NDFI, discuss when and where to apply these aggregations, and present efficient algorithms to approximate their solutions

    Boronic Acid Transition State Inhibitors as Potent Inactivators of KPC and CTX-M β-Lactamases: Biochemical and Structural Analyses

    Design of novel beta-lactamase inhibitors (BLIs) is one of the currently accepted strategies to combat the threat of cephalosporin and carbapenem resistance in Gram-negative bacteria. Boronic acid transition state inhibitors (BATSIs) are competitive, reversible BLIs that offer promise as novel therapeutic agents. In this study, the activities of two alpha-amido-beta-triazolylethaneboronic acid transition state inhibitors (S02030 and MB_076) targeting representative KPC (KPC-2) and CTX-M (CTX-M-96, a CTX-M-15-type extended-spectrum beta-lactamase [ESBL]) beta-lactamases were evaluated. The 50% inhibitory concentrations (IC(50)s) for both inhibitors were measured in the nanomolar range (2 to 135 nM). For S02030, the k(2)/K for CTX-M-96 (24,000 M-1 s(-1)) was twice the reported value for KPC-2 (12,000 M-1 s(-1)); for MB_076, the k(2)/K values ranged from 1,200 M-1 s(-1) (KPC-2) to 3,900 M-1 s(-1) (CTX-M-96). Crystal structures of KPC-2 with MB_076 (1.38-& ANGS; resolution) and S02030 and the in silico models of CTX-M-96 with these two BATSIs show that interaction in the CTX-M-96-S02030 and CTX-M-96-MB_076 complexes were overall equivalent to that observed for the crystallographic structure of KPC-2-S02030 and KPC-2-MB_076. The tetrahedral interaction surrounding the boron atom from S02030 and MB_076 creates a favorable hydrogen bonding network with S70, S130, N132, N170, and S237. However, the changes from W105 in KPC-2 to Y105 in CTX-M-96 and the missing residue R220 in CTX-M-96 alter the arrangement of the inhibitors in the active site of CTX-M-96, partially explaining the difference in kinetic parameters. The novel BATSI scaffolds studied here advance our understanding of structure-activity relationships (SARs) and illustrate the importance of new approaches to beta-lactamase inhibitor design

    Obsessive-Compulsive Disorder in Primary Care: Overview on Diagnosis and Management

    Get PDF
    Background: Obsessive-Compulsive Disorder (OCD) is a debilitating condition marked by the presence of intrusive obsessions and repetitive compulsions. The primary care setting often serves as the first line of contact for individuals grappling with mental health issues, making it a crucial frontier in the early detection and management of OCD. Therefore, the accurate diagnosis of OCD in such settings is essential for effective management. Objective: This review article aims to provide a comprehensive overview of the diagnostic process for OCD, emphasizing the clinical presentation, differential diagnosis, and various diagnostic tools available. Additionally, it explores current strategies for managing OCD, including pharmacological and psychotherapeutic interventions. Methodology: For this review, a comprehensive literature search was conducted using Google Scholar and PubMed databases. Keywords such as "Diagnosis," "obsessive compulsive disorder," and "management" were employed to narrow down relevant studies. Both qualitative and quantitative research papers were included, while non-English publications and those lacking peer-review were excluded. Results: Core symptoms of OCD include obsessions and compulsions, with the Y-BOCS being a standard measure for diagnosis. Differential diagnosis is essential to distinguish OCD from other conditions. SSRIs have been recognized as first-line pharmacological treatments. CBT, particularly Exposure and Response Prevention, remains a potent psychotherapeutic intervention. Emerging treatments like DBS and TMS offer hope for those unresponsive to conventional treatments. Combination therapies have shown enhanced efficacy in certain cases. Conclusion: The meticulous diagnosis of OCD requires recognizing its core symptoms, ruling out other conditions, and leveraging validated clinical tools. A multi-faceted management approach combining pharmacological and psychological treatments ensures optimal patient outcomes, with ongoing research introducing promising new interventions
