Alkali metal complexes of two types of ansa-tris(allyl) ligand are reported; a monoanionic ansa-tris(allyl) ligand containing tin(II) is formally valence isoelectronic to the cyclopentadienyl ligand and a trianionic ansa-tris(allyl) ligand containing silicon(IV) is formally valence isoelectronic to an ansa-metallocene ligand; the potential wider use of these tripodal ligands in coordination che...

Noteworthy, both European agencies most recently have started a discussion toward strategic planning including the tools and ways safety assessments should be done. This represents a major change from their former more receiving and executing roles. It is not clear how much of this change is harmonized and coordinated, e.g., by the Agency Network Scientific Advice54 (ANSA), but they appear rath...

This paper describes the ANSA work-in-progress on an open distributed real-time systems architecture. It examines the problem space and technology bases of open distributed real-time processing. An integrated system architecture is suggested and the benefits of the architecture are presented. It then goes on to outline the important progress of the ANSA phase 3 project to extend the ANSA archit...

Cervical Root Syndrome (CRS) adalah suatu kondisi yang disebabkan oleh iritasi atau kompresi radikulopati servikal tonjolan diskus invertebralis dengan hilangnya sensorik motoric. Telah dilaporkan satu kasus cervical root syndrome pada seorang laki-laki berusia 69 tahun ditegakkan diagnosisnya berdasarkan anamnesis didapatkan nyeri leher berdenyut menjalar ke tangan kiri. Pemeriksaan reflex fis...

Upper airway (UA) muscle activity is stimulated by changes in UA transmural pressure and by asphyxia. These responses are reduced by muscle relaxation. We hypothesized that this is due to a change in afferent feedback in the ansa hypoglossi and/or superior laryngeal nerve (SLN). We examined 1) the glossopharyngeal motor responses to UA transmural pressure and asphyxia and 2) how these responses...

We describe the macroscopic anatomy of the intestine of the giraffe (Giraffa camelopardalis). The small intestine was divided into duodenum, jejunum and ileum as usual. The caecum was attached to the ileum by a long ileocaecal fold, and to the proximal ansa of the ascending colon by a caecocolic fold. The ascending colon was the most developed portion of the gross intestine and had the most com...

We report the synthesis of cyclic cobaltocenium olefins (cationic cobaltocenophane or ansa-cobaltocenium). This is prepared by ring-closing metathesis (RCM) diallyl cobaltocenium, which isomerizes into two different dienes. The isomerization terminal alkene at higher temperature results in thermodynamically more stable internal alkene, supported computational calculation. RCM these isomers prod...

The vagal nerves modulate adrenergic effects on sinus cycle length, atrioventricular (AV) nodal conduction, and refractoriness of atria and ventricles. We tested whether varying levels of vagal-sympathetic input could yield the same spontaneous sinus cycle length but also alter effective refractory periods of the right atrium, right ventricle, and left ventricle and AV nodal conduction times. D...
