The Famished Road: Ben Okri's Family Romance?

2013

International audience; This article suggests that by breaking the cycle of the abiku in The Famished Road, Okri inserts Azaro into a lineage that turns him into a storyteller. It explores the nature of parent-child relationships in the novel from this perspective, using the concept of family romance to show how the association of family with storytelling reverberates in Okri’s writing.

Los i magia - determinanty działania baśniowych postaci

2018

Artykuł poświęcony jest analizie wybranych tekstów baśni braci Grimm pod kątem występowania w nich konkretnych faktorów: losu oraz magii. Rozważania pokazują, pod jakimi względami los determinuje zachowanie bohaterów baśni. Jednocześnie artykuł omawia, w jakim stopniu to magia wpływa na życie postaci we wspomnianych historiach. Całość zmierza do wyznaczenia pewnych typów baśni, w których to los, rozumiany jako nagły obrót wypadków na drodze życiowej bohatera, bądź ciążące nad nim fatum odgrywają zasadnicze znaczenie.

The Future of Antibiotic: From the Magic Bullet to the Smart Bullet

2014

New cerebral protection strategies.

2005

PURPOSE OF REVIEW This article presents an overview of the most recent and important strategies to reduce secondary brain damage. RECENT FINDING There is currently no magic bullet available to protect the brain after neuronal injury. This is related to the complex pathophysiology of cerebral ischemia, which makes it unlikely that a single pharmacological intervention results in sustained neuroprotection. Analyses of clinical studies reveal that acute physiologic derangements (e.g. fever, hypertension and hypotension, hypoxemia, hypercapnia, hyperglycemia) are the most important predictors of unfavorable outcome after brain injury and have to be treated. The effectiveness of anesthetic agent…

A Wasted Inheritance

2012

We all know how Aladdin escapes when the sorcerer traps him in the magic cave. He finds a lamp, rubs it, and a powerful genie appears, who will grant him all his wishes. To start with, he takes him home swiftly, though perhaps not as fast as if he had boarded an Airbus or a high-speed train. Then he loads his table with delicious food, almost as plentiful and varied as can be found in our refrigerators. Finally, he dresses him in luxurious silk clothes, like the ones you can get at the sales in Macy’s. The young boy grows confident and relishes in his pleasant life, taking it for granted that he deserves everything he is profiting from.

Multi-layered, covalently supported ionic liquid phase (mlc-SILP) as highly cross-linked support for recyclable palladium catalysts for the suzuki re…

2011

The reaction between an excess of 1,4-bis(3-vinylimidazolium-1-yl) bromide and a mercaptopropyl-modified amorphous silica gel or ordered mesoporous silica SBA-15 in the presence of azobisisobutyronitrile (AIBN) afforded new materials, which have a high loading of imidazolium moieties. These materials, which contain a highly cross-linked polymeric network, have been denoted as multi-layered, covalently supported ionic liquid phase (mlc-SILP) and have been used as support for palladium catalysts containing a high loading of the metal (10 wt%). Such materials were characterized by several techniques (13C magic angle spinning nuclear magnetic resonance, the Brunauer–Emmett–Teller technique, sma…

Dynamics of cross polarization in solid state nuclear magnetic resonance experiments of amorphous and heterogeneous natural organic substances

2008

Nuclear magnetic resonance (NMR) experiments on carbon-13 in the solid state were done with cross polarization (CP) and magic angle spinning (MAS) in order to overcome the low NMR sensitivity of (13)C and the chemical shift anisotropy, respectively. In the present research, CPMAS (13)C-NMR spectra were collected by modulating the contact time needed for cross polarization (variable contact times experiments, VCT) on two different humic acids (a soil-HA and a coal-HA). VCT data were fitted by a model containing either a monotonic or a non-monotonic cross polarization term. The non-monotonic model, which fitted the experimental results better than the monotonic one, provided two cross-polariz…

Advanced CPMAS-13C NMR techniques for molecular characterization of size-separated fractions from a soil humic acid

2006

A humic acid extracted from a volcanic soil was subjected to preparative high-performance size-exclusion chromatography (HPSEC) to reduce its molecular complexity and eleven different size fractions were obtained. Cross-polarization magic-angle spinning 13C NMR (CPMAS 13C NMR) analysis performed with variable contact-time (VCT) pulse sequences showed that the largest molecular-size fractions contained aromatic, alkyl, and carbohydrate-like components. The carbohydrate-like content and the alkyl chain length seemed to decrease with decreasing molecular size. Progressive reduction of aromatic carbon atoms was also observed with decreasing molecular size of the separated fractions. Mathematica…

Effect of Heating Time and Temperature on the Chemical Characteristics of Biochar from Poultry Manure

2014

Poultry manure (PM) chars were obtained at different temperatures and charring times. Chemical-physical characterization of the different PM chars was conducted by cross-polarization magic angle spinning (CPMAS) (13)C NMR spectroscopy and thermal analysis. CPMAS (13)C NMR spectra showed that the chemical composition of PM char is dependent on production temperature rather than on production duration. Aromatic and alkyl domains in the PM chars obtained at the lowest temperatures remained unchanged at all heating times applied for their production. The PM char obtained at the highest temperature consisted only of aromatic structures having chemical nature that also appeared invariant with hea…
