This paper focuses on the Bahraini regime’s usage of sectarianism as a survival *** argument herein has adopted a modernist approach,where sectarian identities are not viewed as fixed and as causes of an ancient hatred struggle,but are instead viewed as a modern construction that are securitised and *** examines how this particular struggle was framed in a sectarian context through the analysis of three pivotal stages of the 2011 uprising and its *** stages are broken down as follows:(1)the first stage of the uprising,which includes the first month of the uprising and the period prior to the regional military intervention,a period which was characterised by negotiations and dialogue;(2)the period of fragmentation within Bahraini society in which this paper explores the various reasons behind the failed reforms and the failure/ending of dialogue between the regime and the oppositions;and(3)the period of military intervention and the uprising’s aftermath,which reflected a time of securitisation and de-securitisation of the uprising’s space,image and *** three stages showcase overriding factors such as fear,lack of inclusion of alternatives,divided opposition,and limited regime reform which contributed to the Bahraini regime’s brutal reaction to protesters in 2011 and the Qatar-Gulf crisis which emerged in *** three stages reflect the regime’s pragmatism in dealing with the clashes,and its security narrative adjustment to the regional alliance *** Bahraini regime was able to survive the challenges posed by the uprising in the short-term,but its short-term solutions such as the naturalisation process,would have damaging effects on society in the long-run.

We tested the effect of three types of soil inSaudi Arabiaon SABIC carbon steel grade X60 (SCSX60) specimens. The results showed that the environment effect of different condition was very clear, indicating that the studied soils were very corrosive SCSX60 specimens. The composition and morphology of corrosion were different in the tested soil based on moisture content and immersion period. In addition, the results showed that bacteria play an important role in the corrosion of SCSX60. The morphologies of corrosion products were analyzed using scanning electron microscopy to further elucidate the complex systems found in the studied soil.

以8个代表性品种为材料,分析低氮胁迫下青稞苗期的农艺性状和耐低氮能力。结果表明:低氮胁迫下各青稞农艺性状都出现显著差异。所有青稞中株高、植株鲜质量、植株干质量都明显下降,根长、根鲜质量、根干质量都明显上升。但不同品种的根冠比变化差异不同,通过对各农艺性状分析发现,植株和根的鲜质量和干质量更能反映青稞的耐低氮能力,其中根干质量是筛选耐低氮青稞的最重要农艺性状,可以作为青稞耐低氮资源筛选的重要指标。多指标综合分析结果表明,各青稞耐低氮能力为‘昆仑15’>‘黄青1号’>‘肚里黄’>‘昆仑14’>‘昆仑18’>‘二道眉白青稞’>‘洛隆宗’>‘特邬’。

Open Journal of Nursing 2019年第8期9卷 795-800页

Family-centered care is commonly used to describe optimal health care as experienced by families. The main aim of this paper is to recognize the obstacles associated with considering family as client in Saudi Arabia. It is clear that the elements “Recognition of family individuality”, “Developmental needs”, “Parent/professional collaboration”, “Design of the health care system” and “Emotional support for staff” were strongly present in Saudi participants’ practice of family-centered care. The major obstacles of considering family as client are: Lack of staff, limited time to build trust and form relationships, and limited time to negotiate care. Moreover, Saudi participants said that language barriers limited their abilities to communicate with families, which in turn hindered their ability to practice family-centered care. This paper recommends that the approach of family-centered care within the context of nursing education in Saudi Arabia should be included.
