F1 style MGU-H applied to the turbocharger of a gasoline hybrid electric passenger car
Authors: Boretti Albert 
Published: June 2017

AbstractWe consider a turbocharged gasoline direct injection (DI) engine featuring a motor-generator-unit (MGU-H) fitted on the turbocharger shaft. The MGU-H receives or delivers energy to the same energy storage (ES) of the hybrid power unit that comprises a motor-generator unit on the driveline (MGU-K) in addition to the internal combustion engine (ICE). The energy supply from the ES is mostly needed during sharp accelerations to avoid turbo-lag, and to boost torque at low speeds. At low speeds, it also improves the ratio of engine crankshaft power to fuel flow power, as well as the ratio of engine crankshaft plus turbocharger shaft power to fuel flow power. The energy supply to the ES is possible at high speeds and loads, where otherwise the turbine could have been waste gated, and during decelerations. This improves the ratio of engine crankshaft plus turbocharger shaft power to fuel flow power.

Published: June 2017

Abstract
Smallholders in Eastern and Southern Africa(ESA) have limited access to timely availability of quality sweetpotato seed which contributes to sub-optimal root yields. To enhance availability and access to quality seed it is necessary to link formal plant breeding efforts to a sustainable seed supply system by means of identifying business opportunities for sweetpotato Early Generation Seed (EGS) producers. In most ESA countries, public institutions have the sole mandate for EGS production, but have not adopted an explicit business orientation. The study used primary information collected from business plans prepared by eight National Agricultural Research Institutions(NARIs) in seven countries in ESA. This study first analyzed the overall business opportunities for public institutions using a Strengths, Weaknesses Opportunities, and Threats(SWOT) tool and then a Threats, Opportunities, Weaknesses and Strengths (TOWS) approach was used to transform the SWOT results into strategies for the further development of the early generation seed sector. It was concluded that over a five to ten year period, the NARIs do have a business case for production of sweetpotato EGS. However, to capitalise on this NARIs and policy makers need to take up there commendations from the TOWS analysis to refine strategies for exploiting opportunities in the business environment and for mitigating weaknesses to reduce vulnerability to any identified threats to the potential business in EGS.
Blending type approximation by Stancu-Kantorovich operators based on Pólya-Eggenberger distribution
Authors: Kajla Arun , Araci Serkan 
Published: June 2017

Abstract
In the paper the authors introduce the Kantorovich variant of Stancu operators based on Pólya-Eggenberger distribution. By making use of this new operator, we obtain some indispensable auxiliary results. We also deal with a Voronovskaja type asymptotic formula and some estimates of the rate of approximation involving modulus of smoothness, such as Ditzian-Totik modulus of smoothness. The rate of convergence for differential functions whose derivatives are bounded is also obtained.

Abstract
A volumetric ablation model for EPDM (ethylene- propylene-diene monomer) is established in this paper. This model considers the complex physicochemical process in the porous structure of a char layer. An ablation physics model based on a porous structure of a char layer and another model of heterogeneous volumetric ablation char layer physics are then built. In the model, porosity is used to describe the porous structure of a char layer. Gas diffusion and chemical reactions are introduced to the entire porous structure. Through detailed formation analysis, the causes of the compact or loose structure in the char layer and chemical vapor deposition (CVD) reaction between pyrolysis gas and char layer skeleton are introduced. The Arrhenius formula is adopted to determine the methods for calculating carbon deposition rate C which is the consumption rate caused by thermochemical reactions in the char layer, and porosity evolution. The critical porosity value is used as a criterion for char layer porous structure failure under gas flow and particle erosion. This critical porosity value is obtained by fitting experimental parameters and surface porosity of the char layer. Linear ablation and mass ablation rates are confirmed with the critical porosity value. Results of linear ablation and mass ablation rate calculations generally coincide with experimental results, suggesting that the ablation analysis proposed in this paper can accurately reflect practical situations and that the physics and mathematics models built are accurate and reasonable.
Preconcentration of nickel in waters by vortex assisted dispersive liquid-liquid microextraction
Authors: Sánchez-Rojas F. , Bosch-Ojeda C. 
Published: June 2017

AbstractThe present work describes the attempt for the preconcentration of nickel ions by using vortex assisted dispersive liquid-liquid microextraction from aqueous samples. In this method, a small amount of chloroform is rapidly injected by syringe into the water sample containing nickel ions complexed by diethyldithiocarbamate (DDTC).This forms a cloudy solution. The cloudy state is the result of chloroform fine droplets formation, which are dispersed in bulk aqueous sample. Therefore, Ni-DDTC complex is extracted into the fine chloroform droplets and vortex agitation takes place during six minutes. After optimization of experimental variables and determination of analytical characteristics, the method is evaluated for application in real samples. HPLC is used as separation and detection system.
Das gesellschaftlich verantwortliche Agieren von Genossenschaften als Komponente des Membership-Value
Authors: Rößl Dietmar 
Published: June 2017

Abstract
Cooperative banks do not easily generate immediate economic benefit for their members through business relations with them. They try to create meta-economic members’ benefits and to accomplish their mission by acting socially responsible, mostly with regional aspects. The question arises, whether members view these efforts as a part of their benefit. In this article, we answer this question by using a marketing oriented argumentation and an analysis of a cooperative which presents itself as socially responsible.
Zwischen Heteronomie und Autonomie
Authors: Grube Klemens 
Published: June 2017

AbstractNowadays, cooperative banks in Estonia and Latvia are a marginal phenomenon. During the both countries’ first autonomy and before, they figured prominently and were fixed firmly in all classes of population. There were three development phases. We conclude that genesis, prosperity and demise of cooperative banks are linked closely to the political and economic situation of the respective country. The development proceeded similarly in both countries, however the Latvian institutions performed more effectively.

“We Can Make Something Out of Anything”: Sally Potter's Thriller and London's History of Queer Feminist Film Spaces
Authors: Mayer Sophie , Robertson Selina 
Published: June 2017

The National Trust, a British charity founded in 1895 that manages heritage buildings and open spaces for the UK, is now running daytime tours of London's queer club culture from 1918 to 1967 (when the Sexual Offences Act decriminalized private homosexual acts between men over the age of 21), ending at a version of the Caravan, a queer-friendly members' club from 1934 recreated from police records and court reports. Further, the queer activists Sexual Avengers marked 2017's LGBT History month by placing unofficial “Queer Heritage” blue plaques on London landmarks, including one that commemorated the 1988 action against Section 28 in which four lesbians rappelled into the second chamber of the UK Parliament, the House of Lords.
The fiftieth anniversary of the passing of the Sexual Offences Act is being marked this summer by programming at the British Film Institute and other UK cultural institutions. With the National Trust also showcasing the portrait of the Lord Orlando, it is a time when queer histories are clearly entering the mainstream curatorial and cultural spaces and interpretations, making 2017 a productive time to offer a thick description of the complexities of labor, politics, and creative practice that may be smoothed over by this move. At the same time, current queer and feminist spaces in London (as elsewhere in the overdeveloped world) are encountering a recapitulation and intensification of the 1970s version of austerity and precarity that formed both the pretext and subtext of Potter's first film, Thriller (1979), making it an ideal text through which to examine these issues.
Baldwin's Rendezvous with the Twenty-First Century: I Am Not Your Negro
Authors: Crichlow Warren 
Published: June 2017

Thirty years after James Baldwin's untimely death at the age of 63, Haitian-born Raoul Peck makes good on Baldwin's spirited prophecy through his timely and intrepidly titled I Am Not Your Negro (2016). In his rendezvous with Baldwin, Peck carries Baldwin's prescient voice into the twenty-first century, where his rhetorical practice of “telling it like it is” resonates anew in this perilous political moment. Drawing on his signature practice of reanimating the archive through bricolage, Peck not only represents but also remobilizes Baldwin's image repertoire, helping to conjugate the very idea of this revered—and often criticized—novelist and essayist to renewed effect. Like audiences of an earlier era, today's viewers become spellbound by this critical witness's fervent idiomatic eloquence and uncompromising vision.
Crichlow argues that Baldwin's journey is palpably not over—perhaps just beginning. The film makes certain his illuminating prose and penetrating critique continue to assume new meanings in the present, which in turn creates new imaginaries for the future. I Am Not Your Negro augers a significant pedagogical intervention, set to revive knowledge of Baldwin through multifarious viewings, but equally to jump-start the art of reading in schools and communities where a new generation may have little access otherwise to Baldwin's texts. Baldwin had a prophetic sense of his “appointment with the twenty-first century.” In innumerable ways, Raoul Peck's superbly realized I Am Not Your Negro has helped him honor that date.
A rare case of an ACTH/CRH co-secreting midgut neuroendocrine tumor mimicking Cushing's disease

Summary
Ectopic ACTH/CRH co-secreting tumors are a very rare cause of Cushing’s syndrome and only a few cases have been reported in the literature. Differentiating between Cushing’s disease and ectopic Cushing’s syndrome may be particularly difficult if predominant ectopic CRH secretion leads to pituitary corticotroph hyperplasia that may mimic Cushing’s disease during dynamic testing with both dexamethasone and CRH as well as bilateral inferior petrosal sinus sampling (BIPSS). We present the case of a 24-year-old man diagnosed with ACTH-dependent Cushing’s syndrome caused by an ACTH/CRH co-secreting midgut NET. Both high-dose dexamethasone testing and BIPSS suggested Cushing’s disease. However, the clinical presentation with a rather rapid onset of cushingoid features, hyperpigmentation and hypokalemia led to the consideration of ectopic ACTH/CRH-secretion and prompted a further workup. Computed tomography (CT) of the abdomen revealed a cecal mass which was identified as a predominantly CRH-secreting neuroendocrine tumor. To the best of our knowledge, this is the first reported case of an ACTH/CRH co-secreting tumor of the cecum presenting with biochemical features suggestive of Cushing’s disease.

Learning points:

The discrimination between a Cushing’s disease and ectopic Cushing’s syndrome is challenging and has many caveats.

Ectopic ACTH/CRH co-secreting tumors are very rare.

Dynamic tests as well as BIPSS may be compatible with Cushing’s disease in ectopic CRH-secretion.

High levels of CRH may induce hyperplasia of the corticotroph cells in the pituitary. This could be the cause of a preserved pituitary response to dexamethasone and CRH.

Clinical features of ACTH-dependent hypercortisolism with rapid development of Cushing’s syndrome, hyperpigmentation, high circulating levels of cortisol with associated hypokalemia, peripheral edema and proximal myopathy should be a warning flag of ectopic Cushing’s syndrome and lead to further investigations.

Abstract
Epilepsy has many causes and comorbidities affecting as many as 4% of people in their lifetime. Both idiopathic and symptomatic epilepsies are highly heritable, but genetic factors are difficult to characterize among humans due to complex disease etiologies. Rodent genetic studies have been critical to the discovery of seizure susceptibility loci, including Kcnj10 mutations identified in both mouse and human cohorts. However, genetic analyses of epilepsy phenotypes in mice to date have been carried out as acute studies in seizure-naive animals or in Mendelian models of epilepsy, while humans with epilepsy have a history of recurrent seizures that also modify brain physiology. We have applied a repeated seizure model to a genetic reference population, following seizure susceptibility over a 36-d period. Initial differences in generalized seizure threshold among the Hybrid Mouse Diversity Panel (HMDP) were associated with a well-characterized seizure susceptibility locus found in mice: Seizure susceptibility 1. Remarkably, Szs1 influence diminished as subsequent induced seizures had diminishing latencies in certain HMDP strains. Administration of eight seizures, followed by an incubation period and an induced retest seizure, revealed novel associations within the calmodulin-binding transcription activator 1, Camta1. Using systems genetics, we have identified four candidate genes that are differentially expressed between seizure-sensitive and -resistant strains close to our novel Epileptogenesis susceptibility factor 1 (Esf1) locus that may act individually or as a coordinated response to the neuronal stress of seizures.
A Genetic Screen Reveals an Unexpected Role for Yorkie Signaling in JAK/STAT-Dependent Hematopoietic Malignancies inDrosophila melanogaster

Published: June 2017

AbstractA gain-of-function mutation in the tyrosine kinase JAK2 (JAK2V617F) causes human myeloproliferative neoplasms (MPNs). These patients present with high numbers of myeloid lineage cells and have numerous complications. Since current MPN therapies are not curative, there is a need to find new regulators and targets of Janus kinase/Signal transducer and activator of transcription (JAK/STAT) signaling that may represent additional clinical interventions . Drosophila melanogaster offers a low complexity model to study MPNs as JAK/STAT signaling is simplified with only one JAK [Hopscotch (Hop)] and one STAT (Stat92E). hopTumorous-lethal(Tum-l) is a gain-of-function mutation that causes dramatic expansion of myeloid cells, which then form lethal melanotic tumors. Through an F1 deficiency (Df) screen, we identified 11 suppressors and 35 enhancers of melanotic tumors in hopTum-l animals. Dfs that uncover the Hippo (Hpo) pathway genes expanded (ex) and warts (wts) strongly enhanced the hopTum-l tumor burden, as did mutations in ex, wts, and other Hpo pathway genes. Target genes of the Hpo pathway effector Yorkie (Yki) were significantly upregulated in hopTum-l blood cells, indicating that Yki signaling was increased. Ectopic hematopoietic activation of Yki in otherwise wild-type animals increased hemocyte proliferation but did not induce melanotic tumors. However, hematopoietic depletion of Yki significantly reduced the hopTum-l tumor burden, demonstrating that Yki is required for melanotic tumors in this background. These results support a model in which elevated Yki signaling increases the number of hemocytes, which become melanotic tumors as a result of elevated JAK/STAT signaling.
Genome sequencing of two Bell pepper endornavirus (BPEV) variants infecting Capsicum annuum in Colombia
Authors: Muñoz-Baena Laura , Marín-Montoya Mauricio , Gutiérrez Pablo A. 
Published: June 2017

Transcriptome analysis of chili and bell pepper samples from commercial plots in the municipalities of Santa Fe de Antioquia and El Peñol in the province of Antioquia revealed the presence of viral sequences with significant similarity to genomes of members of the genus Endornavirus. Assembly of the chili and bell pepper transcriptomes resulted in consensus sequences of 14,727 nt and 14,714 nt that were identified as Bell pepper endornavirus (BPEV). Both sequences were nearly identical by 99.9 % at both nucleotide and amino acid levels. The presence of BPEV was confirmed by RT-qPCR, RT-PCR and Sanger sequencing using RdRp-specific primers designed from the assembled sequences in ten independent random samples taken from the investigated bell pepper stands. The phylogenetic analysis of both BPEV variants and their affiliation within the genus Endornavirus is discussed. For our knowledge, this is the first study on this group of viruses in Colombia.

Published: June 2017

The relationship between tuber growth and demand for NPK in andigena group of potato (Solanum tuberosum L. ssp. andigena) is poorly documented under conditions of the Andean region of Colombia. It is necessary to establish a specific nutrient management for high yields to changes in edaphic-environmental supply and improve the production of Capiro and Supreme cultivars. Twelve treatments were evaluated at different stages (75-100-125-150 days after planting) of tuber growth using a repeated measures design with three factors: two cultivars (Capiro, Suprema); three locations with contrasting soils (Subachoque, Facatativá, and Choconta) and two levels of fertilization, F0 (unfertilized) and F1 (fertilized) of incomplete nature by differential fertilization by soil type. A positive correlation between fresh weight, dry weight and extraction of N, P and K (kg ha-1) by the tubers, beside harvest extraction index (HEI) was determined. Under optimal conditions of fertilization significant differences (P<0.001) between factor interactions cultivar x phenology x location for accumulation of N and P were detected, where Suprema was less demanding in the HEI of N (1,92 kg t-1 harvest) and HEI of P (0.38 kg t-1 harvest) than Capiro and was better adapted to acid soils of low fertility, in contrast the HEI of K Between 5.28 and 5.34 kg t-1 harvest did not show differences between cultivars due to the genotypic characteristics in the accumulation of dry biomass and starch that make them suitable for industrial use, in addition it was verified that the nutritional extraction depends on the genetic potential determined by the interaction with the environmental and edaphic supply.

Published: June 2017

En este trabajo, se desarrolló un sistema económico de escaneo tridimensional (3D) que permite obtener información de la estructura física de un determinado objeto a partir de la cual, se genera un modelo digital. Este sistema opera proyectando un haz de luz láser en forma de línea sobre el objeto, mientras rota sobre su propio eje (eje z), el haz de luz crea un perfil del objeto, el cual es capturado mediante vídeo de alta definición (HD) por una cámara. A través del procesamiento digital de las imágenes capturadas se obtienen los vértices del objeto y se construye el modelo tridimensional. Para llevar a cabo esta tarea, el escáner 3D está formado por un conjunto de elementos de hardware y software libre como lo son: la plataforma Arduino, que permite realizar el control del hardware de escaneo, y un software desarrollado en C++ que implementando las librerías OpenCv y OpenGl, permite la realización de las tareas de procesamiento y análisis de imágenes. Estos elementos hacen que este desarrollo, se constituya como incursión económica en la tecnología de escaneo laser tridimensional.

Los espectros Mössbauer (EM) fueron ajustados con sextetos, dobletes, singletes y distribuciones de campo hiperfino lo que señala que el orden magnético se ve alterado al sustituir el Tb por el Gd en la composición. Las propiedades magnéticas extrínsecas de la composición en estudio, la caracterizan como materiales magnéticamente semiduros.
