Organoleptic Characteristics of Cookies from Sorghum Composites Flour

Application of wheat flour in various food products has increased the import of wheat flour over years. The use of domestically grown crops like Sorghum (Sorghum bicolor L. Moench) could reduce the demand of wheat. Sorghum flour can be used in partial substitution with wheat flour for many food products, like cookies. The use of sorghum as cookies ingredient could be combined with other flours to get a composite flour. The purpose of this research was to obtain proportion of sorghum flour, sweet potato flour and soyabean flour that produce cookies with good organoleptic characteristics. The proportion of composite flour adequacy was calculated using a list of foodstuffs (DKBM).The research method was based on Experimental Method with Randomized Block Design (RBD) in twelve treatments and two repetitions. The treatments were proportion of sorghum flour (6 minutes, 8 minutes, 10 minutes of dehulling time), sweet potato flour, and soyabean flour. The results showed that cookies made with proportion of sorghum flour, sweet potato flour, and soyabean flour gave no significant difference in organoleptic characteristics (Overall, color, taste, aroma, and hardness).  The result also showed that the characteristics of the cookies were not affected by dehulling of sorghum grains but influenced by other ingredient than flour. Keywords: Sorghum, Sweet Potato Flour,  Soyabean Flour, Cookies, Sensory Propertie

A portable platform for accelerated PIC codes and its application to GPUs using OpenACC

We present a portable platform, called PIC_ENGINE, for accelerating Particle-In-Cell (PIC) codes on heterogeneous many-core architectures such as Graphic Processing Units (GPUs). The aim of this development is efficient simulations on future exascale systems by allowing different parallelization strategies depending on the application problem and the specific architecture. To this end, this platform contains the basic steps of the PIC algorithm and has been designed as a test bed for different algorithmic options and data structures. Among the architectures that this engine can explore, particular attention is given here to systems equipped with GPUs. The study demonstrates that our portable PIC implementation based on the OpenACC programming model can achieve performance closely matching theoretical predictions. Using the Cray XC30 system, Piz Daint, at the Swiss National Supercomputing Centre (CSCS), we show that PIC_ENGINE running on an NVIDIA Kepler K20X GPU can outperform the one on an Intel Sandybridge 8-core CPU by a factor of 3.4

The Effect of Self Help Group on Knowledge and Attitude in Decision Making Among Household Head of Patients with Depression in YOGYAKARTA

Background: Treatment of patients with mental health problem at home and hospital has been so variable and unsatisfactory. An often assumed causal factor of this problem is lack of knowledge among household heads of patients with mental health problem. This study aimed to determine the effect of self help group on knowledge and attitude in decision making among household heads of patients with depression in Yogyakarta.Subjects and Method: This was an analytic experimental study with RCT (Randomized Control Trial). This study was conducted at Jetis, Sleman, Yogyakarta. Study subjects included household heads and 60 patients with depression. The dependent variables were knowldege and attitude in decision making. The independent variable was self health group. The data were collected by use of a set of questionnaire. The data were analyzed by logistic regression.Results: There was positive relationship between engaged in self help group and knowledge (OR= 1.46, 95% CI= 1.33-14.02, p= 0.015) among household heads of patients with depression. There was positive relationship between being engaged in self help group and attitude, but it was statistically non-significant (OR= 1.46, 95% CI= 0.74-25.41, p= 0.105).Conclusion: Self help group has positive significant effect on household head's knowledge, as well as attitude in decision making among household heads.Keywords: self help group, knowledge, attitudeCorrespondence: Endang Tri Sulistyowati.

Flexión compuesta esviada en secciones de hormigón armado doblemente simétricas. Dirección de capacidad máxima

The use of simplified stress-strain relationship to describe the behavior of the concrete in compression (rectangular parabola, rectangular block), leads to find that the maximum capacity of a double symmetric reinforced concrete section under axial load an biaxial bending in the main symmetrical axis of the section. For the same section, the use of hyperbolic stress-strain relationship to describe the concrete behavior is found that the maximum capacity of the section under elevated compression level and biaxial bending does not lay in the symmetry axis direction but in an arbitrary one. A collection of interaction diagrams, biaxial bending an axial load, (Mx, My) of two sections with different amount of steel and two different axial loads are calculated in this research for two different stress-strain relationship for concrete (rectangular parabola, and hyperbolic), in order to find the direction of maximum resistance of the section under axial load and biaxial bending.El uso de modelos constitutivos simplificados para caracterizar el comportamiento del hormigón, (parábola rectángulo, bloque rectangular), conduce a que la capacidad de agotamiento de una sección doblemente simétrica solicitada por un axil excéntrico se encuentre en la dirección de simetría principal. Si se evalúa la capacidad de la sección empleando un modelo hiperbólico para la descripción del hormigón se obtiene que para axiles elevados, la dirección de resistencia máxima presenta un cierto desvío respecto a la dirección de simetría principal tal como se obtiene con el uso de modelos simplificados. En este trabajo se determinan y comparan una serie de diagramas de interacción en flexión compuesta esviada (Mx, My) de dos secciones con cuantías y axiles crecientes y dos modelos constitutivos de hormigón (parábola rectángulo e hiperbólico) a fin de determinar la dirección en la que se encuentra la resistencia máxima de las secciones en los casos analizados

ORB5: a global electromagnetic gyrokinetic code using the PIC approach in toroidal geometry

This paper presents the current state of the global gyrokinetic code ORB5 as an update of the previous reference [Jolliet et al., Comp. Phys. Commun. 177 409 (2007)]. The ORB5 code solves the electromagnetic Vlasov-Maxwell system of equations using a PIC scheme and also includes collisions and strong flows. The code assumes multiple gyrokinetic ion species at all wavelengths for the polarization density and drift-kinetic electrons. Variants of the physical model can be selected for electrons such as assuming an adiabatic response or a ``hybrid'' model in which passing electrons are assumed adiabatic and trapped electrons are drift-kinetic. A Fourier filter as well as various control variates and noise reduction techniques enable simulations with good signal-to-noise ratios at a limited numerical cost. They are completed with different momentum and zonal flow-conserving heat sources allowing for temperature-gradient and flux-driven simulations. The code, which runs on both CPUs and GPUs, is well benchmarked against other similar codes and analytical predictions, and shows good scalability up to thousands of nodes

Optique: Zooming in on Big Data

Despite the dramatic growth of data accumulated by enterprises, obtaining value out of it is extremely challenging. In particular, the data access bottleneck prevents domain experts from getting the right piece of data within a constrained time frame. The Optique Platform unlocks the access to Big Data by providing end users support for directly formulating their information needs through an intuitive visual query interface. The submitted query is then transformed into highly optimized queries over the data sources, which may include streaming data, and exploiting massive parallelism in the backend whenever possible. The Optique Platform thus responds to one major challenge posed by Big Data in data-intensive industrial settings

Ontology Based Data Access in Statoil

Ontology Based Data Access (OBDA) is a prominent approach to query databases which uses an ontology to expose data in a conceptually clear manner by abstracting away from the technical schema-level details of the underlying data. The ontology is ‘connected’ to the data via mappings that allow to automatically translate queries posed over the ontology into data-level queries that can be executed by the underlying database management system. Despite a lot of attention from the research community, there are still few instances of real world industrial use of OBDA systems. In this work we present data access challenges in the data-intensive petroleum company Statoil and our experience in addressing these challenges with OBDA technology. In particular, we have developed a deployment module to create ontologies and mappings from relational databases in a semi-automatic fashion; a query processing module to perform and optimise the process of translating ontological queries into data queries and their execution over either a single DB of federated DBs; and a query formulation module to support query construction for engineers with a limited IT background. Our modules have been integrated in one OBDA system, deployed at Statoil, integrated with Statoil’s infrastructure, and evaluated with Statoil’s engineers and data

Global turbulence features across marginality and non-local pedestal-core interactions

Spatially non-local aspects of turbulent transport in tokamak plasmas are examined with global gyrokinetic simulations using the ORB5 code. Inspired by very accurate measurements in the TCV tokamak in L-mode, we initialise plasma profiles with constant logarithmic gradients in the core and constant linear gradients in the 'pedestal' ($\rho \in [0.8,\,1]$). The main finding is that transport in the core is strongly affected by the presence of pedestal gradients. This non-local pedestal-core coupling appears to be correlated with the appearance of repetitive avalanches that propagate across both pedestal and core regions. Below a certain threshold value in pedestal gradient, no well-defined frequency is found for avalanches. Above this threshold, a well-defined frequency shows up, which roughly matches that of the local geodesic acoustic mode (GAM) frequency near the plasma edge and is thus well below the local GAM frequency in the core: this behaviour is very similar to the global coherent mode structure observed in TCV. Above this threshold in pedestal gradient, the core transport increases sharply: there is therefore a non-locality in marginality. The probability density functions (PDFs) of density, temperature, temperature gradient and potential are found to have nearly Gaussian distributions, whereas the heat flux can have, in the presence of avalanches, a more or less strongly positively skewed PDF, which could be fitted by a log-normal distribution. The skewness of the heat flux is found to be radially and non-locally dependent: its value in the plasma core critically depends on the presence of gradients in the pedestal. The relation flux versus gradient is examined in detail. The local instantaneous flux versus gradient relation shows a hysteresis behaviour during an avalanche but no clear correlation, unlike the flux and zonal flow (ZF) shearing rate, which are anti-correlated: flux is higher when shearing rate is lower. This leads to corrugated time-averaged radial profiles of transport, heat and temperature gradient, with heat diffusivity having local maxima where the ZF shearing rate goes to zero and temperature gradient has local minima. Finally, we show how the flux versus gradient relation can be analysed locally for series of simulations with different averaged gradients
