A field experiment was conducted under rainfed conditions in western Sudan at El-Obeid Research Farm and Eldemokeya Forest Reserve, North Kordofan State, during the growing seasons 2004/05 and 2005/06. The main objective was to investigate the soil physical and chemical properties and yield of groundnut (Arachis hypogea), sesame (Sesamum indicum) and roselle (Hibiscus sabdariffa) of an Acacia senegal agroforestry system in comparison with the sole cropping system. Data were recorded for soil physical and chemical properties, soil moisture content, number of pods per plant, fresh weight (kg ha^−1) and crop yield (kg ha^−1). The treatments were arranged in Randomized Complete Block Design (RCBD) and replicated four times. Significant differences (P < 0.05) were obtained for sand and silt content on both sites, while clay content was not significantly different on both sites. The nitrogen (N) and organic carbon were significantly (P < 0.05) higher in the intercropping system in Eldemokeya Forest Reserve compared with sole cropping. Soil organic carbon, N and pH were not significant on El-Obeid site. Yet the level of organic carbon, N, P and pH was higher in the intercropping system. Fresh weight was significantly different on both sites. The highest fresh weight was found in the intercropping system. Dry weights were significantly different for sesame and roselle on both sites, while groundnut was not significantly different. On both sites intercropping systems reduced groundnut, sesame and roselle yields by 26.3, 12 and 20.2%, respectively. The reduction in yield in intercropping plots could be attributed to high tree density, which resulted in water and light competition between trees and the associated crops.

Brushy Creek is a tributary of the Raccoon River, which is a regular source of drinking water for over 400,000 Iowans. Regular monitoring by Des Moines Water Works (DMWW) and Agriculture’s Clean Water Alliance (ACWA) over the last eight years has shown the stream to be highly impaired for coliform bacteria and nitrate. Both Brushy Creek and the Raccoon River are on the 303(d) impaired waterbody list. A December 2005 fish kill in Brushy Creek resulted in administrative actions against seven livestock producers. Several open feed lots exist in the watershed. The community of Roselle (in the Brushy Creek watershed) has been identified by IDNR as unsewered, and many dwellings throughout the watershed discharge untreated human waste. No Watershed Improvement Association (WIA) exists in this sparsely-populated area. This outcome-based project will: • Enhance nutrient and manure management to reduce agricultural inputs to the stream. • Assess the amount of human waste reaching the stream from Roselle. • Engage and inform local residents so a WIA can be formed. • Monitor performance through a rigorous water and soil testing program. This project embraces a concept of participation from all levels of government, commodity organizations, and the private sector. The largest drinking water utility in the state will lead and administer this effort. The participating parties will work to establish a functioning WIA so that progress achieved through this project will be robust and long-lasting. The participants believe this will be the most effective approach to correct the situation, and will serve as a model for other problem watersheds throughout the state.

The calyxes of Hibiscus sabdariffa are used in traditional medicine around the world. However, quality assurance protocols and chemical variability have not been previously analyzed. In the present study, chemical characterization of a set of samples of H. sabdariffa calyxes commercialized in Colombia was accomplished with the aim to explore the chemical variability among them. Chemometrics-based analyses on the data obtained from the HPLC-UV-DAD-derived profiles were then performed. Thus, the pre-processed single-wavelength data were subjected to principal component analysis (PCA). The PCA-derived results evidenced different groups which were well-correlated to the corresponding total phenolic and total anthocyanin contents. Multi-wavelength chromatographic (HPLC-UV-DAD surfaces) data were additionally examined via parallel factor analysis (PARAFAC) as data reduction method and the obtained loadings were subsequently submitted to PCA and orthogonal partial least squares discriminant analysis (OPLS-DA). Results were thus consistent with those from single-wavelength data. PCA loadings were employed to determine those chemical components responsible for the data variance and OPLS-DA model, constructed from PARAFAC loadings, and indicated differentiation according total anthocyanin contents among samples. The present chemometric analysis therefore demonstrated to be an excellent tool for differentiation of H. sabdariffacalyxes according to their chemical composition.

Tässä tutkielmassa käsittelen ateismia ihmisoikeusaktivisti Ernestine L. Rosen (1810–1892) ajattelussa. Ernestine Rose syntyi ja varttui nykyisen Puolan alueella juutalaisghetossa. Varakkaan rabin tyttärenä hän sai juutalaistytöksi poikkeuksellisen laajan koulutuksen, mutta jo varhain hän luopui uskostaan ja myöhemmin julistautui eksplisiittisesti ateistiksi. Lähdettyään kotimaastaan hän matkusti ympäri valistuksen tuulien muovaamaa Eurooppaa, opiskeli ja päätyi lopulta Englantiin, jossa hän tutustui utopistisosialisti Robert Oweniin ja liittyi tämän seuraajiin owenisteihin. Englannista hän muutti vuonna 1836 Yhdysvaltoihin, missä hän teki pääasiallisen uransa universaalien ihmisoikeuksien puolestapuhujana. Hän toimi orjuuden vastaisessa liikkeessä ja taisteli sekä naisten oikeuksien että uskonnottomuuden puolesta. Lähestyn tutkimuskysymystäni ateismin merkityksestä pääasiassa Ernestine Rosen julkisten puheiden ja lehtikirjoitusten kautta. Rosen julkista elämää lukemalla ja kontekstualisoimalla pyrin ymmärtämään sitä, mitä ateismi merkitsi Roselle ja hänen ihmisoikeusajattelulleen. Määrittelen työni uskonnottomuuden kulttuurihistoriaksi. Tarkastelen ateismia elettynä kokemuksena, tapana ymmärtää, jäsentää ja olla osa ympäröivää todellisuutta. Keskeisessä roolissa tutkimuksessani on myös sukupuoli, joka määritti 1800-luvulla Rosen valtaaman julkisen tilan vahvasti maskuliiniseksi tilaksi, kun naisen alueeksi määrittyi yksityisen piiri, koti. Uskonnon ja uskonnottomuuden suhde osoittautui työssäni moniulotteiseksi. Erottautumalla sanoin ja teoin juutalaisuudesta Rose rakensi itselleen ateistin identiteetin, mutta hänen ymmärryksensä juutalaisuudesta erosi kuitenkin protestanttitaustaisten vapaa-ajattelijoiden käsityksestä ja muovasi hänen uskontokritiikkiään omaan suuntaansa. Vahvasti antiklerikaaliseen, mutta uskonnolliseen retoriikkaan nojanneissa reformiliikkeissä hänen retoriikkaansa näyttäytyi myös poikkeuksellisena. Ateismi toi haasteita hänen uralleen, koska naiseuteen kytkeytyi vahvasti ajatus uskonnollisuudesta: uskonnoton nainen oli luonnonoikku ja uhka yhteiskunnalliselle järjestykselle. Samalla ateismista kummunnut näkökulma oli Roselle vahvuus, joka loi uudenlaisia ajattelumahdollisuuksia, jotka kuitenkin kytkeytyivät vahvasti ajan kulttuuriin ja käsityksiin.

Bien que le changement dans le choix des substrats énergétiques des acides gras (AGs) vers les glucides soit considéré comme bénéfique pour le cœur insuffisant, il n’est pas clair à savoir pourquoi les patients atteints de désordres de la β-oxydation (β-OX) des AGs à chaîne longue (AGCLs) développent des troubles du rythme et des cardiomyopathies. De plus, le traitement actuel ne permet pas de prévenir l’apparition du phénotype clinique chez tous les patients, spécifiquement en condition de jeûne ou de stress. Ainsi, plusieurs modèles de souris déficientes pour des enzymes impliquées dans l’oxydation des acides gras ont été développés de manière à améliorer les connaissances de la maladie ainsi que les traitements offerts aux patients. À cet égard, cette étude vise à évaluer le phénotype métabolique et fonctionnel des cœurs de souris déficientes pour le récepteur activé de la prolifération des peroxysomes-α (PPARα), un facteur de transcription des gènes impliqués notamment dans la β-OX des AGs, et pour la déshydrogénase des acyl-CoA à très longue chaîne (very-long chain acyl-CoA dehydrogenase, VLCAD), le déficit de l’oxydation des AGCLs le plus commun chez l’humain. L’approche expérimentale utilisée comprend plusieurs techniques dont (i) la perfusion ex vivo de cœur de souris au travail combinée à l’utilisation de substrats marqués au carbone 13 (13C) et à l’analyse par chromatographie gazeuse-spectrométrie de masse (GCMS), (ii) l’analyse de l’expression génique par qPCR et (iii) l’analyse de l’activité électrique du cœur in vivo par télémétrie. De manière inattendue, les résultats de cette étude menée chez la souris ont permis de mettre en évidence que des déficits pour des protéines impliquées dans l’oxydation des AGCLs sont associés à des altérations du métabolisme (i) des glucides, (ii) des AGs polyinsaturés (AGPIs), et (iii) mitochondrial, incluant l’anaplérose, en plus d’être liés à des désordres de la fonction électrique du cœur, à savoir une prolongation du segment QTc. Pris dans leur ensemble, les résultats de cette thèse pourraient servir à l’élaboration de nouvelles interventions métaboliques destinées à améliorer les traitements possibles et donc, la qualité de vie des patients atteints de désordres héréditaires de la β-OX des AGCLs.

La presente monografía pretende explorar la cooperación Sur-Sur en el marco de los BRICS como una estrategia de soft power de estos Estados para aumentar su liderazgo global. Lo anterior se constituye como un elemento fundamental en la consolidación de los BRICS como un foro político y ha permitido el inicio de un proceso de cohesión identitaria dentro del grupo, lo que a su vez ha generado que actúen conjuntamente en diferentes espacios. El análisis se hace a través de la aproximación teórica de la hegemonía cooperativa de Thomas Pedersen y el concepto de soft power desarrollado por Joseph Nye, lo que permite no solo caracterizar a los miembros del grupo BRICS sino que también da lugar a identificar sus aspiraciones en el foro y en torno a qué temas u objetivos se unen.

Transduction of energetic signals into membrane electrical events governs vital cellular functions, ranging from hormone secretion and cytoprotection to appetite control and hair growth. Central to the regulation of such diverse cellular processes are the metabolism sensing ATP-sensitive K+ (KATP) channels. However, the mechanism that communicates metabolic signals and integrates cellular energetics with KATP channel-dependent membrane excitability remains elusive. Here, we identify that the response of KATP channels to metabolic challenge is regulated by adenylate kinase phosphotransfer. Adenylate kinase associates with the KATP channel complex, anchoring cellular phosphotransfer networks and facilitating delivery of mitochondrial signals to the membrane environment. Deletion of the adenylate kinase gene compromised nucleotide exchange at the channel site and impeded communication between mitochondria and KATP channels, rendering cellular metabolic sensing defective. Assigning a signal processing role to adenylate kinase identifies a phosphorelay mechanism essential for efficient coupling of cellular energetics with KATP channels and associated functions.
