Development, Nutrient Composition and Sensory Properties of Biscuits Produced from Composite Flour of Wheat and African Yam Bean

The aim of the study was to improve the protein content of biscuit; a low protein but widely consumed snack by school-aged children. The study was carried out at the Department of Crop Utilization; International Institute of Tropical Agriculture (IITA), Ibadan between March, 2012 and December, 2012. Composite flour was produced from African yam bean (a nutrient-dense but underutilized legume) flour (AYBF) and wheat flour (WF). The composite flour was prepared at various ratios WF/AYBF 100:0, 80:20, 70:30 and 60:40.and used to produce biscuits. These biscuits samples were analysed and the 100/0 WF: AYBF biscuit served as control. Proximate analysis, crispness (breaking force) and sensory evaluation of the biscuit samples were determined using standard methods. Proximate analysis showed significant increase (P=.05) in protein (9.6114.71%), ash (1.37-2.42%) and sugar (14.11-21.29%) and significant decrease in starch (76.66-51.15%) and fat (12.53-8.13%) contents with increase in AYBF in the biscuits. There was no significant difference in the moisture contents of the test samples. Crispness of the biscuit increased with increase in percentage of AYBF in the flour blend. The breaking force values reduced from 8.5kg (for 100/0 WF: AYBF biscuits) to 3.0kg (60/40 WF: AYBF biscuits). Lower breaking force was found to correspond with higher crispness. Sensory evaluation results showed that all biscuit samples had high rating for Original Research Article British Journal of Applied Science & Technology, 4(13): 1925-1933, 2014 1926 all evaluated attributes. The closeness of values obtained for all biscuit samples to the control sample indicate a high level of acceptance of the AYBF-WF biscuits. Hence, suggesting a way of obtaining biscuits with higher protein content.
Effects of Air Pollution on Citrus Trees

Agricultural crops can be injured when exposed to concentrations of various air pollutants. Injury ranges from visible markings on the foliage, to reduced growth and yield, to premature death of the plant. The development and severity of the injury depends not only on the concentration of the particular pollutant, but also on a number of other factors. These include the length of exposure to the pollutant, the plant species as well as the environmental factors conducive to a build-up of the pollutant. Effects on vegetation vary and can appear just after short periods of exposure to high concentrations of air pollutants resulting in acute effects, or chronic effects after long exposure periods to low concentrations. This review describes documented effects of air pollutants, such as ozone, fluoride, sulfur dioxide, acidic precipitation and other pollutants on citrus trees, describes the mechanisms of injury and damage of the air pollutants to the plant, discusses the suitability of using dose vs. exposure to define the air pollutant uptake and analyses the past trends and future research needs in the field of effects of air pollutants on citrus trees. _____________________________________________________________________________________________________________
The Smagorinsky turbulence model

This bachelor thesis considers the Smagorinsky turbulence model and its derivation. The model is used to simulate turbulent flows around a surface mounted cube in a rectangular channel with the code MooNMD. Emphasis is placed on the lift and drag force on the cube and the respective coefficients. The numerical results of the mean drag coefficients for different choices of the turbulent viscosity constant are compared to some other studies that consider this benchmark problem. ∗https://www.wias-berlin.de/people/john/ †https://www.wias-berlin.de/~ahmed/ Author’s Declaration of Originality I hereby declare that this thesis is my original work and it has been written by me in its entirety.

Entropy Generation in MHD Conjugate Flow with Wall Shear Stress over an Infinite Plate: Exact Analysis

The current work will describe the entropy generation in an unsteady magnetohydrodynamic (MHD) flow with a combined influence of mass and heat transfer through a porous medium. It will consider the flow in the XY plane and the plate with isothermal and ramped wall temperature. The wall shear stress is also considered. The influences of different pertinent parameters on velocity, the Bejan number and on the total entropy generation number are reported graphically. Entropy generation in the fluid is controlled and reduced on the boundary by using wall shear stress. It is observed in this paper that by taking suitable values of pertinent parameters, the energy losses in the system can be minimized. These parameters are the Schmitt number, mass diffusion parameter, Prandtl number, Grashof number, magnetic parameter and modified Grashof number. These results will play an important role in the heat flow of uncertainty and must, therefore, be controlled and managed effectively.

This process consists of three phases: (I) inflammation, (II) formation of new tissue with deposition of extracellular matrix, and (III) tissue remodeling. Tissue repair shows a specific signaling network involving different cells and can be modulated by fatty acids. Several studies have demonstrated the benefits of treating wounds topically with fatty acids, e.g., (a) fatty acids cost little and are widely used by the population in several countries; (b) oily damp dressings offer a natural barrier against microorganisms, preventing tissue dehydration, maintaining body temperature and diminishing trauma when dressings are changed; (c) studies about the functions of fatty acids and immune cells have shown the important immunomodulatory character of fatty acids; and (d) a nutritional deficiency of fatty acids may impair tissue r epair, prolonging the wound healing process. This review focuses on the physiological mechanisms involved in the wound healing process and on the effects of fatty acids as potential of this process.

Herschel/PACS far-IR spectral imaging of a jet from an intermediate mass protostar in the OMC-2 region

We present the first detection of a jet in the far-IR [O I] lines from an intermediate mass protostar. We have carried out a Herschel/PACS spectral mapping study in the [O I] lines of OMC-2 FIR 3 and FIR 4, two of the most luminous protostars in Orion outside of the Orion Nebula. The spatial morphology of the fine structure line emission reveals the presence of an extended photodissociation region (PDR) and a narrow, but intense jet connecting the two protostars. The jet seen in [O I] emission is spatially aligned with the Spitzer/IRAC 4.5 micron jet and the CO (6-5) molecular outflow centered on FIR 3. The mass loss rate derived from the total [O I] 63 micron line luminosity of the jet is 7.7 x 10^-6 M_sun/yr, more than an order of magnitude higher than that measured for typical low mass class 0 protostars. The implied accretion luminosity is significantly higher than the observed bolometric luminosity of FIR 4, indicating that the [O I] jet is unlikely to be associated with FIR 4. We argue that the peak line emission seen toward FIR 4 originates in the terminal shock produced by the jet driven by FIR 3. The higher mass-loss rate that we find for FIR 3 is consistent with the idea that intermediate mass protostars drive more powerful jets than their low-mass counterparts. Our results also call into question the nature of FIR 4.
The influence of the global photochemical composition of the troposphere on European summer smog, Part I: Application of a global to mesoscale model chain

Elevated mixing ratios of ozone in the lower troposphere are a major summer time air pollution issue in Europe. Photochemical in-situ production is the most important source of ozone in the planetary boundary layer and has been studied extensively. However, the contributions of background ozone due to stratospheric intrusions, lightning nitrogen oxide followed by ozone production, convective mixing and intercontinental transport are still poorly quantified. We analyze in this paper the influence of the large-scale ozone background on near-surface ozone throughout a summer smog period in July 1994 over Europe. For this purpose a chain of global to mesoscale models is applied with a nesting procedure coupling the individual model simulations. It is found that background ozone as determined by the global model dominates the results of the higher resolution limited area models increasingly with height. But improvements of limited area model results are not only restricted to the free troposphere. Strong convective events like thunderstorms couple free tropospheric and planetary boundary layer air masses so that ozone from above is injected into the planetary boundary layer contributing an amount of 5–10 ppbv to nearsurface ozone in the afternoon hours. A decrease in the same range of 5–10 ppbv in maximum near-surface ozone over Central Europe is found in a model simulation where European anthropogenic emissions are reduced by 25%, an amount equal to the reported emission trends in Germany from 1994 to 2000. We conclude that intercontinental transport of pollution can obscure the results of local efforts to reduce critical exposure levels of ozone.
How to Detect and Remove Temporal Autocorrelation in Vehicular Crash Data

Temporal autocorrelation (also called serial correlation) refers to the relationship between successive values (i.e. lags) of the same variable. Although it has long been a major concern in time series models, however, in-depth treatments of temporal autocorrelation in modeling vehicle crash data are lacking. This paper presents several test statistics to detect the amount of temporal autocorrelation and its level of significance in crash data. The tests employed are: 1) the Durbin-Watson (DW); 2) the Breusch-Godfrey (LM); and 3) the Ljung-Box Q (LBQ). When temporal autocorrelation is statistically significant in crash data, it could adversely bias the parameter estimates. As such, if present, temporal autocorrelation should be removed prior to use the data in crash modeling. Two procedures are presented in this paper to remove the temporal autocorrelation: 1) Differencing; and 2) the Cochrane-Orcutt method.
A COMPACT FINITE DIFFERENCE SCHEME FOR SPACE-TIME FRACTIONAL DIFFUSION EQUATIONS WITH TIME DISTRIBUTED-ORDER DERIVATIVE

In this paper, we present a compact finite difference scheme for the Dirichlet problem of a class of space-time fractional diffusion equations with time distributedorder derivative, where the time fractional derivative is defined in the sense of Caputo derivative, and the space fractional derivative is defined by the Riesz derivative. The term involving time distributed-order derivative is discretized by use of the compound Simpson formula, and the Caputo fractional derivative is approximated by the Lagrange interpolation formula, while the Riesz space fractional derivative is approximated by the compact fractional center difference formula. The proposed difference scheme is proved to be uniquely solvable, unconditionally stable and convergent with accuracy of fourth order in both space and time directions. Numerical experiments for supporting the theoretical analysis are given.
Online IMU Self-Calibration for Visual-Inertial Systems

Low-cost microelectro mechanical systems (MEMS)-based inertial measurement unit (IMU) measurements are usually affected by inaccurate scale factors, axis misalignments, and g-sensitivity errors. These errors may significantly influence the performance of visual-inertial methods. In this paper, we propose an online IMU self-calibration method for visual-inertial systems equipped with a low-cost inertial sensor. The goal of our method is to concurrently perform 3D pose estimation and online IMU calibration based on optimization methods in unknown environments without any external equipment. To achieve this goal, we firstly develop a novel preintegration method that can handle the IMU intrinsic parameters error propagation. Then, we frame IMU calibration problem into general factors so that we can easily integrate the factors into the current graph-based visual-inertial frameworks and jointly optimize the IMU intrinsic parameters as well as the system states in a big bundle. We evaluate the proposed method with a publicly available dataset. Experimental results verify that the proposed approach is able to accurately calibrate all the considered parameters in real time, leading to significant improvement of estimation precision of visual-inertial system (VINS) compared with the estimation results with offline precalibrated IMU measurements.
Social Network Analysis on Location-Based Recommender Systems written by Bardia Khalesi Supervisors :

The growth of social networks in the last few years and their importance in societies lead to directing a large amount of attention to social network analysis on the one hand, and personalized recommendation systems on the other hand. However, most of recommender systems focus on personal profiles of users to estimate the recommendations and do not consider social groups to which users can be related. In this thesis, we aim to investigate the impact of social groups on preference of individuals in social networks, and consequently on the effectiveness of recommender systems. Therefore, we propose a unified framework to incorporate a number of collaborative filtering systems based on different social groups to assess the social influence of each of them on the behavior of users. Experimental results show that social groups play an effective role in making relevant suggestions. Furthermore, people share their information about venues via their comments. This information is spread through the network and used by other users to decide to attend any of available venues or not. Thus, to benefit from this flow of information in social networks, we try to utilize natural language processing methods to extract users’ opinion from their comments. In this manner, our informed recommender illustrates the influence of information cascading and also an admissible evidence of positive/negative relationships’ impact in making more accurate recommendations.
Ultrafast laser inscribed 3D integrated photonics

Since the discovery, that a tightly focused femtosecond laser beam can induce a highly localized and permanent refractive index change in a wide range of dielectrics, ultrafast laser inscription has found applications in many elds due to its unique 3D and rapid prototyping capabilities. These ultrafast laser inscribed waveguide devices are compact and lightweight as well as inherently robust since the waveguides are embedded within the bulk material. In this presentation we will review our current understanding of ultrafast laser - glass lattice interactions and its application to the fabrication of inherently stable, compact waveguide lasers and astronomical 3D integrated photonic circuits.
Unravelling the Factors Influencing Construction Organisations’ Intention to Adopt Big Data Analytics in South Africa

The construction industry has been producing massive data that can be transformed for improved decision-making and better construction project delivery. However, the industry has been adjudged as a slow adopter of digital technologies such as big data analytics (BDA) to improve its service delivery. The implication of this slow adoption is the lack of innovativeness and unsustainable project delivery that has characterised the industry in most countries, particularly in developing ones like South Africa. Therefore, this study assessed the intention to adopt BDA by construction organisations using the unified theory of technology adoption and use of technology (UTAUT) model. A post-positivism philosophical stance was employed, which informed the use of quantitative research with a questionnaire designed to solicit information from construction organisations in South Africa. Data analysis was done using Cronbach alpha to test for reliability and Fuzzy Synthetic Evaluation to evaluate the impact of the different constructs of the UTAUT on the adoption of BDA by construction organisations in South Africa. The study found that variables relating to facilitating conditions, performance expectancy, and social influence will significantly impact an organisation’s intention to adopt BDA. However, issues surrounding effort expectancy, resistance to use, and perceived risk cannot be overlooked as they also have high impact levels. The study provides an excellent theoretical and practical contribution to the existing discourse on construction digitalisation.
Maybe Eventually? Towards Combining Temporal and Probabilistic Description Logics and Queries

We present some initial results on ontology-based query answering with description logic ontologies that may employ temporal and probabilistic operators on concepts and axioms. Speci_cally, we consider description logics extended with operators from linear temporal logic (LTL), as well as subjective probability operators, and an extended query language in which conjunctive queries can be combined using these operators. We first show some complexity results for the setting in which either only temporal operators or only probabilistic operators may be used, both in the ontology and in the query, and then show a 2ExpSpace lower bound for the setting in which both types of operators can be used together.
Full polarization structure of the OH main‐line maser envelopes of W Hydrae

Simultaneous MERLIN observations of the OH 1665- and 1667-MHz maser lines in the circumstellar envelope of the semiregular star W Hya have been taken in all Stokes parameters. The 1665-MHz emission comes from two elongated clusters located 80 au from the star. The 1667-MHz emission arises in an incomplete shell of radius 130 au, with the blueshifted features located in the northern part of the envelope and the redshifted components clustered south of the centre. The circularly polarized maser components exhibit spatial separation along the north–south direction. The linearly polarized components were found from the near side of the envelope. Their polarization position angles indicate that the projected axis of the magnetic field at PA ≃ −20° is consistent with spatial segregation of circular polarization. The intensity of the magnetic field, estimated from a tentative measurement of Zeeman splitting, is about 0.6 mG at the location of the 1667-MHz emission, with the field pointing away from the observer. A small change of position angles of linear polarization observed in both maser lines is interpreted as a weak Faraday effect in the maser regions with an electron density of about 2 cm−3. The overall polarization structure of the envelope suggests an ellipsoidal or weak bipolar geometry. In such a configuration, the circumstellar magnetic field may exert a non-negligible influence on mass loss. The velocity field in the circumstellar envelope recovered from observations of SiO, H2O, OH and CO lines at five radial distances reveals a logarithmic velocity gradient of 0.25 and 0.21 in the 1665- and 1667-MHz maser regions respectively. The acceleration within tens of stellar radii cannot be explained by the classical model of radiation pressure on dust.

Thermal Decomposition and the Non-Isoththermal Decomposition Kinetics of DL-2-Naproxen

The thermal decomposition process and non-isothermal decomposition kinetic of DL-2-naproxen were studied by the Differential Thermal Analysis(DTA) and Thermogravimetric Analysis(TGA). The results show that the thermal decomposition temperature of DL-2-naproxen is in the range of((250.72~296.87)±4.88)℃. The melting point and the melting enthalpy of DL-2-naproxen were measured to be(158.16±0.6)℃ and(140.57±2.10) J·g-1,respectively,by Differential Scanning Calorimetry(DSC). The mechanism function and kinetic parameters of non-isothermal decomposition of DL-2-naproxen were obtained from the analysis of DTA-TGA curves by both Achar and COATS-Redfern methods.The kinetic equation of DL-2-naproxen decomposition obtained shows that the decomposition reaction is a second order reaction,its activation energy and preexponential factor obtained are 201.558 kJ·mol-1 and 7.52×1024 s-1,respectively.The basic data obtained are available for the application,engineering design and industry production of DL-2-naproxen.
Integration of Smart Grid Technologies in Households: How Electric Vehicles and Dynamic Pricing change Social Practices in the Everyday Life?

This article considers the interplay between new smart grid technologies and households’ everyday practices. The research focuses on how Electric Vehicles and Dynamic Pricing influence Danish households’ everyday life and how these technologies constitute and change routines and practices of consumption. The basic assumption is that new technologies influence social practices in households’ everyday life. The empirical material, mainly consist of qualitative interviews with Danish households who had test-driven Electric Vehicles and participated in Project Dynamic Pricing, is analysed with the analytical concept offered by the Social Practice Theory. Overall, the case-study demonstrates that the smart grid technologies influence the ‘way of driving’ and changed the temporal patterns of consumption in the families during the test period. The investigation contribute to a more complex and multi-facetted consideration of the interplay between households’ social practices and new smart-grid technologies and thereby helping to fill out the lack of research on the integration of peak-shaving technologies in the end-user design.
