Production and quality evaluation of garri-like product from sweet potatoes

The potential of sweet potato as a source of producing a Garri-like product using the conventional cassava Garri processing Technology was examined. Four (4) samples were produced with varied fermentation periods; SPF–1 (24 hours), SPF-2 (48 hours), SPF-3 (72hours), while SPNF was not fermented. The proximate composition shows that the three (3) days fermentation sample (SPF-3) has a higher protein content of 3.58%. The ash content was observed to increase with fermentation period of a day (24hours) and subsequently decreased with increase in fermentation period from 1.82% (SPF-2) to 1.41% (SPF-3) respectively. The water absorption capacity increased directly with the length of fermentation period from 7.70% (SPNF) to 8.16% for SPF–3. PH decreased from 7.18 to 6.16 and TTA increased from 0.12% to 0.27% respectively, with increased fermentation period. There was significant difference in all the sensory attributes of the four (4) sweet potato Garri samples. However, sample SPF- 3 is most preferred in terms of taste. Sensory attributes of SPNF and SPF-1 were not significantly different.
Morphological plasticity in Zostera muelleri across light, sediment, and nutrient gradients in Australian temperate coastal lakes

Biomass and morphometrics of Zostera muelleri were monitored across depth, sediment type, and nutrient gradients in 2 coastal lakes (Tuggerah Lakes and Lake Macquarie) on the east coast of Australia. Tuggerah Lakes had significantly higher nutrient, chlorophyll a, and suspended sediment concentrations in the water column and significantly higher fine sediment fraction and sediment organic matter content. Seagrass above-ground biomass (AGB) was significantly greater in the mesotrophic Tuggerah Lakes, while below-ground biomass (BGB) was significantly greater in the oligotrophic Lake Macquarie, most likely reflecting the different nutrient status of the lakes. Light gradients were the primary control over total biomass, BGB, and shoot density across the study area. Although no general trends between light and AGB were found in this study, lakeand site-specific relationships between light, AGB:BGB ratios, and leaf area index were seen to vary along gradients in nutrient status and sediment quality. These trends are thought to be driven by morphological acclimation that allows seagrass to maintain favourable plant carbon and net community metabolism balances while minimising sulphide exposure. Seagrass depth limits were best predicted by a multilinear model including Secchi depth, fine sediment fraction, and organic matter content, suggesting that negative feedbacks associated with sulphide exposure in the rhizosphere increased the minimum light requirements of this species. Our results support an emerging view that sediment quality and nutrient status are important controls over minimum light requirements in seagrasses. Morphological plasticity can moderate but not completely compensate for the negative impacts of sediment properties on minimum light requirements.
Dynamics of the Yellowstone hydrothermal system

The Yellowstone Plateau Volcanic Field is characterized by extensive seismicity, episodes of uplift and subsidence, and a hydrothermal system that comprises more than 10,000 thermal features, including geysers, fumaroles, mud pots, thermal springs, and hydrothermal explosion craters. The diverse chemical and isotopic compositions of waters and gases derive from mantle, crustal, and meteoric sources and extensive water‐gas‐rock interaction at variable pressures and temperatures. The thermal features are host to all domains of life that utilize diverse inorganic sources of energy for metabolism. The unique and exceptional features of the hydrothermal system have attracted numerous researchers to Yellowstone beginning with the Washburn and Hayden expeditions in the 1870s. Since a seminal review published a quarter of a century ago, research in many fields has greatly advanced our understanding of the many coupled processes operating in and on the hydrothermal system. Specific advances include more refined geophysical images of the magmatic system, better constraints on the time scale of magmatic processes, characterization of fluid sources and water‐rock interactions, quantitative estimates of heat and magmatic volatile fluxes, discovering and quantifying the role of thermophile microorganisms in the geochemical cycle, defining the chronology of hydrothermal explosions and their relation to glacial cycles, defining possible links between hydrothermal activity, deformation, and seismicity; quantifying geyser dynamics; and the discovery of extensive hydrothermal activity in Yellowstone Lake. Discussion of these many advances forms the basis of this review.
CONDITIONS FOR THE PROPAGATION OF MEMORY PARAMETER FROM DURATIONS TO COUNTS AND REALIZED VOLATILITY

We establish sufficient conditions on durations that are stationary with finite variance and memory parameter $d \in [0,{\textstyle{1 \over 2}})$ to ensure that the corresponding counting process N(t) satisfies Var N(t) ~ Ct2d+1 (C > 0) as t → ∞, with the same memory parameter $d \in [0,{\textstyle{1 \over 2}})$ that was assumed for the durations. Thus, these conditions ensure that the memory parameter in durations propagates to the same memory parameter in the counts. We then show that any autoregressive conditional duration ACD(1,1) model with a sufficient number of finite moments yields short memory in counts, whereas any long memory stochastic duration model with d > 0 and all finite moments yields long memory in counts, with the same d. Finally, we provide some results about the propagation of long memory to the empirically relevant case of realized variance estimates affected by market microstructure noise contamination.
Coral reproduction at Hall Bank, a high latitude coral assemblage in Western Australia

Research on coral reproduction has increased dramatically in recent times; however, there remain significant regions, in particular high latitude reefs, where research is limited. For example, the reproductive biology of species in the coral assemblage at Hall Bank, a high latitude site (32 degrees S) in southern Western Australia, remain unknown. Here, reproductive traits and the likely time of spawning for 12 of the approximately 16 species that occur at Hall Bank were established using histology between March 2009 and March 2011 at 7 discrete time points. Peak reproductive activity most likely occurs in February, as 7 of the 10 species sampled in this month had colonies with mature gametes. The sexuality, mode of larval development and transmission of symbionts were, as expected, consistent with previous work. The reproductive biology of the corals at Hall Bank is consistent with other regions of the Indo-Pacific, supporting the hypo thesis that reproductive traits such as sexuality and mode of larval development are evolutionarily conserved and do not vary biogeographically.
Thermoelastohydrodynamics of grease-lubricated concentrated point contacts

Abstract Isothermal and thermoelastohydrodynamic lubrication (TEHL) analyses of grease lubricated bearings are presented. A grease plug flow is formed in the conjunction that, with no shear at the boundaries with the solid surfaces, adheres to them in the region of high pressures under isothermal conditions. The elastohydrodynamic lubrication grease pressure distribution conforms fairly closely to that of its base oil alone, with the exception of inlet trail and pressure spike regions. The dependency of film thickness on speed (rolling viscosity) and load parameters for the base oil agrees with previously reported findings of the research community. For grease there are subtle differences with the base oil film thickness load and speed dependencies. However, it is clear that extrapolated oil film thickness formulae for oils can be used reasonably for the prediction of grease films, at least as a first approximation. The results presented agree well with optical interferometric measurements reported in the literature for grease-lubricated contacts at low temperatures and low surface velocities. TEHL analysis shows breakdown of the plug flow and significant reduction in film thickness, which can lead to changes in the regime of lubrication to mixed or boundary conditions.
Android Application Install-time Permission Validation and Run-time Malicious Pattern Detection

The open source structure of Android applications introduces security vulnerabilities that can be readily exploited by third-party applications. We address certain vulnerabilities at both installation and runtime using machine learning. Effective classification techniques with neural networks can be used to verify the application categories on installation. We devise a novel application category verification methodology that involves machine learning the application permissions and estimating the likelihoods of different categories. To detect malicious patterns in runtime, we present a Hidden Markov Model (HMM) method to analyze the activity usage by tracking Intent log information. After applying our technique to nearly 1,700 popular third-party Android applications and malware, we report that a major portion of the category declarations were judged correctly. This demonstrates the effectiveness of neural network decision engines in validating Android application categories. The approach, using HMM to analyze the Intent log for the detection of malicious runtime behavior, is new. The test results show promise with a limited input dataset (69.7% accuracy). To improve the performance, further work will be carried out to: increase the dataset size by adding game applications, to optimize Baum-Welch algorithm parameters, and to balance the size of the Intent sequence. To better emulate the participant's usage, some popular applications can be selected in advance, and the remainder can be randomly chosen.

Bilingual Colombia: What does It Mean to Be Bilingual within the Framework of the National Plan of Bilingualism? Colombia Bilingüe: ¿Qué significa ser bilingüe en el marco del Plan Nacional de Bilingüismo?

This article is a partial research report of a critical discourse analysis of the document “Estandares basicos de competencias en lenguas extranjeras: ingles. Formar en lenguas extranjeras: iel reto! ” (Basic standards for competences in foreign languages: English. Teaching in foreign languages: The challenge! ). The analysis was informed by theory on critical discourse analysis (CDA) and on symbolic power (particularly language as symbolic power). In an attempt to interpret what it means to be bilingual in Colombia according to this document, the data show that 1) Being bilingual means speaking English; and 2) Bilingualism is constructed as a packed, monolithic and homogeneous concept.
Characterization of six microsatellite loci in the African wild silk moth (Gonometa postica, Lasiocampidae)

Six microsatellite markers were developed for the African wild silk moth, Gonometa postica (Lasiocampidae), using an enrichment protocol. The total number of alleles ranged from three to 17 for a sample of 130 individuals across the distribution of the species. Observed levels of heterozygosity ranged from 0.17 to 0.78. Deviation from Hardy–Weinberg equilibrium detected in some loci is probably the result of large interannual population size fluctuations characteristic of this species. No evidence of linkage disequilibrium was detected among loci. These loci will be useful for the inference of demographic processes in a moth species that is of potential economic importance.
Prevalence and economic significance of bovine fasciolosis in Nekemte Municipal abattoir

A cross-sectional study was carried out from November, 2011 to March, 2012 at Nekemte municipal abattoir to assess prevalence and economic significance of bovine fasciolosis. Out of 384 cattle examined at post mortem, 21.9% (84) were positive for fasciolosis. The prevalence of bovine fasciolosis was found to be significantly affected (P 0.05) affecting the prevalence of disease. The prevalence of Fasciola hepatica was 14.1% (54), which was predominant among Fasciola species, causing bovine fasciolosis in the study areas. Whereas, the prevalence of Fasciola gigantica was 5.2% (20), and 2.6% (10) animals were mixed infected. The economic significance of bovine fasciolosis was also assessed based on condemned livers. Thus, based on retail value of bovine liver, the direct economic loss from fasciolosis during the study time was estimated to be 63072 ETB annually. Key words: Cattle, economic significance, Fasciola gigantica, Fasciola hepatica, prevalence, post mortem examination.
Soyfood Consumption Patterns: Effects of Product Attributes and Household Characteristics

Effects of perceived attributes of soyfoods on the consumption patterns for six different soyfood products are evaluated. Perceived attributes include convenience, health benefits, and taste. The soyfood products are tofu, vegetable burgers, soy milk, soy supplements, meat substitutes, and soy cheese. This study uses a conceptual model that highlights the role of perceived attributes in a demand model by combining Lancaster’s characteristics model with Fishbein’s multi-attribute model. A binary-choice model and a zero-inflated negative binomial model (ZINB) are used as empirical specifications to address the zero consumption of soyfood products. Results show that perceived health attributes of soyfood have differential effects across the six soyfood products. Convenience of preparation and consumption as well as taste have strong effects across soyfood products. The study identifies several socio-economic characteristics of consumers that have a significant influence on soyfood consumption patterns. Implications for the food industry are discussed in relation to the differential effects of health attributes and socio-demographic variables.
Trade Liberalisation Does Not Always Raise Wage Premia: Evidence from Ugandan Districts

The process of economic integration over the past two decades has been accompanied by an expanding income wedge between skilled and unskilled workers in many developing countries. This was also the case for Ugandan wage employees during the 1990s, which was a period of abrupt trade opening and market reforms. This is a surprising result for an unskilled labour abundant country like Uganda in light of a standard Heckscher-Ohlin (H-O) framework. But was the trade opening responsible for the increase in wage premia? By using a novel district-level analysis, I find that in fact increased trade reduced the returns to schooling in line with the H-O predictions. On the other hand, the intensification of domestic trade across districts during the period was associated with higher returns in those districts relatively endowed with skilled employees. This effect appears to be responsible for at least some of the rising returns to schooling among wage employees in Uganda.
A Convexity Theorem For Symplectomorphism Groups

In this thesis, the topological, algebraic and geometric properties of the subgroup of equivariant symplectomorphisms of a symplectic toric manifold are studied. It is shown that this subgroup is a maximal Abelian and path connected “Lie subgroup” of the full symplectomorphism group which is flat and totally geodesic with respect to the canonical weak metric induced by the canonical Kaehler metric. Moreover, an infinite-dimensional version of the Schur-Horn-Kostant convexity theorem is presented which is obtained after an appropriate completion of algebras.
Lysekil Research Site, Sweden : A status update

Ocean wave energy can be harnessed and converted into electric energy nowadays. This provides a possibility for populations that live on islands or along coastlines to utilize the renewable and safe power produced by ocean waves. Point absorbing wave energy converter (WEC) is one example of such devices for electrical power production from ocean waves. It is composed of a floating buoy on the water surface, and a linear generator that sits on seabed and is connected with the buoy via a line. Electricity is generated when the buoy moves up and down in the waves.The geometry and dimensions of the floating buoy have dominant influences on the energy absorption. This thesis introduces an equivalent electric circuit for modelling the hydrodynamic interaction between the wave and a cylindrical buoy. The model allows a rapid assessment of the velocity, force in the connection line and output power, by which the system design and optimization can be performed faster and easier.The electric circuit model is based on the WEC's dynamic force analysis, and the electric components' parameters are determined from analytical approximations of the hydrodynamic coefficients. The simulation results of the equivalent circuit for one typical wave climate in Lysekil has been presented, and the results indicate a good fitting with former experimental results.The thesis also includes a hydrodynamic study for a torus shaped buoy, which aims at applying a theoretical background for a force measurement experiment. A comparison has been conducted between the torus buoy and two similar cylindrical buoys. Preliminary WAMIT simulation results demonstrate that the force in the connection line will be 5% bigger by using the torus buoy. It is also found that the torus buoy is advantageous for its larger excitation force and smaller added mass. A brief introduction of the 500kN force measurement system and the communication test have been introduced as well.
The Application of Good Agriculture Practices(GAP) of Shallot in Bantul Regency

Bantul Regency is one of the center of shallots in Indonesia, but its productivity is low. In 2015, the productivity of shallots in Bantul Regency was 7.66 tons/ha. The application of Good Agriculture Practices (GAP) is a form of technology adoption aiming to improve the shallot productivity.The purposes of this study are to determine the level of application of shallots GAP in Bantul Regency and to find out the factors influencing the application such as land area, farmers’ age, farmers’ education, farming experience, availability of farm inputs, and extension service frequency. Purposive technique was used to determine the research location. Sanden and Kretek districts were discovered since these areas are the production centers of shallots in Bantul Regency. The study involved the respondents consisting of sixty shallot farmers, thirty people from Kretek District and the other thirty people from Sanden District who were determined by simple random sampling. This research used scoring technique with Likert scale to measure the application level of GAP. Multiple linear regression analysis was used to understand the factors affecting the application of GAP of shallots. Result showed that the application of GAP of shallots in Bantul Regency is low. The factors of land area, farmers’ education, farming experience, and availability of farm inputs means infl uence the application level of GAP of shallots significantly.
Salt stress enhancement of antioxidant and antiviral efficiency of Spirulina platensis.

Cultivation of Spirulina platensis under salt stress conditions (0.02 M as control), 0.04 and 0.08 M NaCl led to a remarkable alteration of algal metabolism as well as an enhancement or induction of biologically active compounds. Concerning algal growth, salt stress caused a decrease in dry weight, chlorophyll a content as well as certain xanthophylls (neoxanthin and violaxanthin) while β-carotene production was stimulated especially at higher salt concentrations. Biochemical analysis of salt stressed algal revealed that lipid content was slightly increased together with certain saturated and unsaturated fatty acids especially the polyunsaturated ones (γ-inolenic acid, omega 3 fatty acid). Electrophoretic analysis of soluble protein pointed out that certain high molecular weight protein bands were not detected comparing with the protein marker. Five new protein bands of molecular weights 190, 158, 113, 77 and 28 KDa were recorded, in addition to an increase in the intensity of 6 already existing bands. Phosphate buffer and water extracts of the algal exhibited antiviral activities against both Hepatitis-A-virus-type-MBB (HAV-MBB strain, RNA virus) and Herpes simplex-virus-type-1 (HSV-1, DNA virus). Water extracts were found to be more effective than phosphate buffer extracts in inducing antiviral activities (98%) especially against HSV-1 virus. The same water extract of the salt stressed algal demonstrated higher anticoagulating activity compared with those of heparin and the positive control measured by clotting time assay. Antioxidant activity of the algal successive extracts against 2, 2 diphenyl-1-picrylhydrazyl and 2,2'- azino-bis (ethylbenzthiazoline-6- sulfonic acid) radical methods revealed moderate antioxidant activity of the non-polar algal extracts (petroleum ether) which were doubled with increasing extract concentration. The lowest activity was recorded by the partially polar (ethyl acetate) algal extract of both concentrations at all salinity levels. While the polar extracts (ethanol and water) showed higher antioxidant activities which were doubled with increasing extract concentration. Ethanolic algal extract (100 µg/ ml at 0.08 M NaCl) exhibited the highest antioxidant activity compared with those of the synthetic antioxidant butylated hydroxy anisol as standard (85.0, 89.9 and 86.0, 91.8% respectively). Key words: Spirulina platensis, antioxidant-antivirus, biochemical studies, salt stress.
The disruptive behavior disorders and the coexisting deficits in the context of theories describing family relations

Summary Aim. The aim of the study is to understand behavior disturbances and widely comprehended deficits at- tached to it, with regards to quality of family relations. Method. To explain the etiology and the consequences of the diagnosis of disruptive behavior disorder the authors analyzed literature which allowed combining the theory of attachment and the theory of def- icits. In the first part of the script the authors described Bowlby's theory of attachment, which arranges attachment behaviors in behavioral attachment system. To expand comprehension of the subject they mentioned psychoanalytic and system concepts. The second part of the paper is devoted to the defini- tion of deficit phenomenon and determining its different areas on the basis of observations made by the researchers dealing with this matter. Conclusion. In authors' opinion the deficits occurring in children suffering from disruptive behavior disor- der are connected with improper family relations. The disruptive behavior disorders may be a way of de- fense against narcissistic injury as well as motor discharging of the emotional difficulties. attachment theory / disruptive behavior disorders in children and adolescents / deficit
