Antihyperglycaemic effect of hydroalcoholic extract from Punica granatum L. peels in normal and streptozotocin-induced diabetic rats and its potent α-amylase inhibitory.

This study was designed to evaluate the antidiabetic effect of hydroalcoholic extract from Punica granatum peels in normal and streptozotocin-induced diabetic rats and its potent a-amylase inhibitory. Antidiabetic effect of this extract was investigated after oral administration at dose of 400 mg/kg b.w. In normal fasted rats, the test drug extract showed no hypoglycaemic effect but were found to be depressing the peak value of blood glucose after oral glucose tolerance (glucose 2.5 g/kg b.w.). After 2-weeks of daily treatment in streptozotocin-induced diabetic rats, plasma glucose levels were decreased after oral administration of hydroalcoholic extract from Punica granatum peels by 56% in the first week and 32.92% in the second week. However, this extract showed hypolipidemic effect (Total cholesterol and triglycerides) in streptozotocin-induced diabetic rats. In vitro, Punica granatum peels extract demonstrate a potent inhibitory effect on a- amylase activity (IC50=3.65 g/L) these finding strongly suggest that PGP extract improves postprandial hyperglycaemia, at least in part, by inhibiting alpha amylase activity.
Context and Technological Pedagogical Content Knowledge (TPACK): A Systematic Review

Abstract Context is an important aspect of educational research and the technological pedagogical content knowledge (TPACK) framework, but is often missing from TPACK research, or its specific meaning is not clear. To provide a systematic and comprehensive view of the extent to which context is included in such research, and to understand the meaning of context when it is included, we conducted a systematic review of publications about TPACK. Context was included in descriptions, explanations, or operationalizations of TPACK among 36% of the 193 empirical journal articles we examined. When context was included, classroom and school factors and those related to teachers were more likely to be included than those related to students and society. The grounds for context being included among around one-third of the articles and why some contextual factors are examined more than others are discussed. Implications for practice and recommendations for future research focus on investigating the complexity of practice, the development of measures that include context, and aligning TPACK and educational technology research with other disciplines through greater attention to context.

Density of juvenile and mature wood of selected coniferous species

The objective of research was to determine the density of juvenile (JW) and mature wood (MW) of selected coniferous species growing in the Czech Republic. The research included the wood of Norway spruce (Picea abies (L.) Karst. ), Scots pine (Pinus sylvestris L.) and European larch (Larix decidua Mill.). The juvenile wood density close to the pith was 410 kg·m for spruce, 391 kg·m for pine and 573 kg·m for larch with 12% water content. Mature wood in the peripheral parts had the higher density in all species – spruce 516 kg·m, pine 552 kg·m and larch 652 kg·m. The highest difference, the difference of 161 kg·m, between juvenile and mature wood was found out in Scots pine. The large difference in the wood density of pine is caused by a considerable difference in the mean ring width of its juvenile and mature wood. Further, it was proved that wood density decreases with the increasing ring width while wood density increases with the increasing proportion of latewood.
IDENTIFYING BOUNDARIES FOR THE APPLICATION OF REAL OPTIONS TO BUSINESS STRATEGY

The concept of real options has generated considerable interest within the management literature in recent years. The appeal of the framework is natural given the high degree of uncertainty that firms face in their investment decisions. Little attention, however, has been paid to what distinguishes a real option from other path-dependent investment processes. We argue that the critical distinctions stem from the degree to which the criteria for whether or not to continue with a course of action (i.e., a option) can be specified ex-ante. While the real option framework is designed to address uncertainty, options are structured around particular sets of possible actions. To the extent that choice sets (not only outcome values) evolve as a consequence of prior actions, the real option framework is less applicable. A common violation of this boundary condition occurs when initial efforts that prove unsuccessful with regard to the intended market or technical agenda raise the possibility of success in the context of other markets or different technical agendas. The flexibility associated with the notion of real options stems from the possibility of abandonment. As a result, the boundaries of applicability of real options to business strategy are, in important respects, a function of organizational design and project management. We argue that maintaining this flexibility requires an off-setting rigidity in the boundaries of search processes. However, preserving the applicability of real options by imposing rigid criteria for abandonment may result in the underutilization of discoveries made in the course of initial investments and search efforts. The organizational rigidity required to maintain the flexibility of abandonment may therefore cause real options to be an inferior mechanism of resource allocation relative to other search processes (e.g., March and Simon, 1958; Burgelman, 1983; Kanter, 1988; Lynn, Morone, Paulson, 1996) in many strategic settings.
Bivariate density estimation in an Oriented Cylinder Model

The microstructure of an object of dual phase steel is modelled with an Oriented Cylinder Model, where the martensite grains in the steel object are modelled as oriented cylinders that are randomly distributed within a big block. By cutting this block parallel to the cylinder axes, rectangular visible profiles of the cut cylinders can be observed from the cut-plane. To translate the two-dimensional information about the rectangles to three-dimensional information about the cylinders, an inverse relationship between the bivariate probability density function of the height and squared half-width of a rectangle and the bivariate density of the height and squared radius of a cylinder is established. The former density is estimated by a bivariate modified Gamma kernel density estimator, and the relationship between the two densities is used to numerically transform this estimator into an estimator for the latter density. For the selection of the bandwidth parameters of the kernel density estimator, both a method based on the Integrated Squared Error of the kernel density estimator and a method based on the Integrated Squared Error of the transformed estimator are considered. The estimator for the height and squared radius of a cylinder is constructed for the underlying density of an example data set as well as for the underlying density of an experimental data set. These bivariate estimators are used to construct an estimator for the marginal density of the squared radius of a cylinder and the density of the volume of a cylinder.
Climate mitigating information to consumers by food retailers

Human food consumption contributes to climate change and changing consumption patterns towards a more vegetable-based diet could decrease GHG emissions. However, such change is difficult to achieve due to ingrained habits, cultural and social norms and culinary preferences, highlighting a need to understand consumer behaviour and find efficient strategies for communicating the issue within supermarkets. To encourage a change to a more vegetable-based diet, product development is necessary for vegetables to be perceived as tasty, convenient and easy to use. However consumers revealed strong negative environmental associations to packaging of potato, which highlights the present challenges for producers wishing to use packaging to communicate positive benefits and thus increase the perceived convenience of such products. An initial analysis of actual availability of climate-mitigating information on food in supermarkets, showed that it was poorly communicated by retailers. A further investigation on information (climate friendly and organic) and atmospherics (nature sounds) revealed that nature sounds only influenced male participants’ willingness to buy (WTB) organic. It also revealed that depending on their connectedness to nature (CtN), information either raised or lowered male participants’ WTB organic or climate-friendly products. Finally, tests were performed on an informative tool, the Swedish Meat Guide, which aims to communicate the link between food and climate and to help direct food choice towards less environmentally damaging alternatives, such as vegetables. The complex concept of climate mitigating information means that the knowledge and understanding, as well as suggested actions, have to be communicated on multiple levels and by multiple stakeholders, taking into consideration the great difference in knowledge levels and motives between consumers. Climate mitigating information needs to be better promoted among food retailers and consumers. Also, other attempts to increase vegetable consumption - product development, nudging, promotional efforts - may indirectly support a climate mitigating food consumption.
A research on civil engineering students' past video game playing experiences

Within the scope of this paper, past video game playing experiences of civil engineering students is investigated in order to identify the most preferred video game classifications that were played as an engineer candidate and its contribution to their education. A questionnaire practice is chosen and questions are randomly distributed to the civil engineering students. This technique is applied to 200 civil engineer candidates to figure out their past video game preferences before becoming a member of civil engineering department. The analysis of the questionnaire results indicates that the top three game classes in the interest of civil engineering students are: Strategy, Sports and Simulation. On the other hand, it is also observed that the less played genres are: Art Games, Action – Adventure and music games. Furthermore, results of the analysis are compared with the students weighted points. Outcomes are striking that there is a stable correlation between the students playing strategy games and their success points.
Adjusting Minimal Maintenance Margin Requirement When Price Limits Widening

This study aims at to investigate whether the minimal maintenance margin requirement (MMMR) need to adjust considering sufficient safety of the credit trading when the regulators in Taiwan Stock Exchange widen the price limits. Based on different confidence interval, risks, and multiple simulations of portfolios, we estimate Value-at-Risk (VaR) by GARJI model to derive the MMMR threshold according to the upper bound of MMMR. Furthermore, as a key reference of index future in TAlFEX, we establish a credit security degree for standardizing to compare the difference between maintenance margin requirement in spots and future market. Our empirical results show that the MMMR at 120% could be slightly insufficient to secure claims under widening to reach 10% price limits. On the other hand, the credit security degree of instantaneous maintenance margin in spots market might approximate to futures market. This study provides the critical economical implicate for policy makers to set the optimal MMMR when the price limits widen.
Cyclic Proofs for Linear Temporal Logic

Annotated sequents provide an elegant approach for the design of deductive systems for temporal logics. Their proof theory, however, is notoriously difficult. It is not even clear how to syntactically show the admissibility of weakening. In this paper, we establish weakening by purely proof-theoretic methods, thus solving an open problem by Brünnler and Lange. We also investigate the role of cut in annotated sequent systems.
Efficacy safety and patient acceptability of the combined chlormadinone acetate-ethinylestradiol oral contraceptive.

Emergence and evolution of sophisticated chemical scaffolds of lignin polymers providing mechanical support for plant tissues, protecting the plant from pathogen invasion and damaging UV, and enhancing the hydrophobicity of the plant vasculature was of paramount importance to land plant evolution and their adaptation to the local ecosystems. Recruitment of enzymes from primary metabolism and their evolutional modification led to biosynthesis of H and G lignin in early terrestrial plants. Evolutional advantage of S lignin in adaptation to environment was a result of the selective structural alterations of the ring modification enzymes such as ferulate 5-hydroxylase and caffeic acid/5-hydroxyferulic acid O-methyltransferase at later stages of evolution. Lignification consequently transformed phenylpropanoid metabolism into a major sink for carbon in plants estimated to represent as much as 30% of the total biomass produced in the biosphere. Significant progress in plant genomics and in sequencing of the plant species that occupy important positions within the evolutionary history of plants along with functional studies of the families of lignin-specific genes in these plants allowed us in-depth understand how lignin biosynthesis was originated and evolved. Accumulated knoweledge also triggered new strategies for targeted re-programming lignin biosynthesis to improve agricultural and economic values of the crops as the great sugar sources for animal feed and biofuels production. Here we review the current knowledge about different aspects of lignin biosynthesis including its evolution, regulation and targeted modification to improve plant cell wall composition for animal health and for biofuel production.
A pedagogy of Multiliteracies Designing Social Futures

THE NEW LONDON GROUP 1 In this article, the New London Group presents a theoretical overoiew of the connec­ tions between the changing social environment facing students and teachers and a new approach to literacy pedagogy that they call "multiliteracies. " The authors argue that the multiplicity of communications channels and increasing cultural and lin­ guistic diversity in the world today call for a much broader view of literacy than portrayed by traditional language-based approaches. Multiliteracies, according to the authors, overcomes the limitations of traditional approaches by emphasizing how ne­ gotiating the multiple lingustic and cultural differences in our society is central to the pragmatics of the working, civic, and private lives of students. The authors maintain that the use of multiliteracies approaches to pedagogy will enable students to achieve the authors' twin goals for literacy learning: creating access to the evolving language of work, power, and community, and fostering the critical engagement necessary for them to design their social futures and achieve success through fulfilling employment. If it were possible to define generally the mission of education, one could say that its fundamental purpose is to ensure that all students benefit from learning in ways that allow them to participate fully in public, community, and economic life. Literacy pedagogy is expected to play a particularly important role in ful­ filling this mission. Pedagogy is a teaching and learning relationship that creates the potential for building learning conditions leading to full and equitable social participation. Literacy pedagogy has traditionally meant teaching and learning
Transformation d ’ Escherichia coli et sélection des clones recombinés

Lactic acid bacteria isolated from local raw cow’s milk are still not well known about their potentialities and genetic performances. Many research group are interested by the different biologicals properties carried by plasmids of these bacteria. Extraction and purification of a 5,3 Kb cryptic plasmid was established in Lactobacillus casei. This plasmid, designed pSU100, has been cloned in the vector of transformation pUC18 localized in the EcoRI site of E. coli JM103. Electrophoretic properties of restriction which has been obtained by simple, double and treple digestions with 33 endonucleases, those digestions permitted the construction of a restriction map of this plasmid. Five single sites have been identified, as well as double and many other sites. A preliminary examination of the physiological properties permitted to identify an antibiotic resistance for Kanamycine.
Amino acids digestibility of pelleted microparticle protein of fish meal and soybean meal in broiler chickens

Commom protein sources for poultry, fish meal and soybean meal, were ground to obtain reduced particle size. The particle was then dissolved in distilled water (1 : 4 w/v), and added with 2 mL virgin coconut oil for every 500 mL solution prior to ultrasound transducer (ultrasonic bath) treatment to obtain protein microparticle. Reducing particle size is one possible way to increase protein utilization. 180 birds were used for forced feeding and 10 other birds were plotted for endogenous correction, when they were one month and a half old. Microparticle protein of both ingredients were tested separately in either mash or pelleted forms and compared to intact protein. Completely randomized design with 3 treatments (intact, mash, and pellet) and 6 replications (10 bidrs each) was arranged for the respective ingredient. Protein and essential amino acid digestibilities, and calcium retention were the parameters measured. Analysis of variance continued to Duncan test were applied to statistically evaluate the data. Pelleted microparticle protein of fish meal and soybean meal, respectively, resulted in significantly (P<0.05) highest protein and amino acids digestibilities, and Ca retention although lower disgestibility of fewer amino acids was found in mash form. In conclusion, pelleted form of microparticle protein of either fish meal or soybean meal improve protein and mostly amino acids digestibilities, and calcium retention in broiler.
Segmental Modification of the Mualem Model by Remolded Loess

The measured diffusion coefficient and soil-water characteristic curve (SWCC) of remolded loess were used to modify the Mualem model for increasing its accuracy. The obtained results show that the goodness of fit between the Mualem model and the variable parameter-modified Mualem method comparing with the test results was not high. The saturation of 0.65 was introduced as the boundary to divide the curve of the measured diffusion coefficient into two segments. When the segmentation method combined with the variable parameter method was used to modify the Mualem model, the fitting correlation coefficient was increased to 0.921–0.998. The modified parameters and corresponding to remolded loess were calculated for different dry densities. Based on the exponential function between and dry density and the linear relation between and dry density, the segmentally modified Mualem model was established for remolded loess by considering variation in dry density. The results of the study can be used for directly determining the unsaturated infiltration coefficient and for indirectly determining the SWCC through diffusion coefficient.
Title How do singularities move in potential flow ?

The equations of motion of point vortices embedded in incompressible flow go back to Kirchhoff. They are a paradigm of reduction of an infinite-dimensional dynamical system, namely the incompressible Euler equation, to a finite-dimensional system, and have been called a “classical applied mathematical playground”. The equation of motion for a point vortex can be viewed as the statement that the translational velocity of the point vortex is obtained by removing the leading-order singularity due to the point vortex when computing its velocity. The approaches used to obtain this result are reviewed, along with their history and limitations. A formulation that can be extended to study the motion of higher singularities (e.g. dipoles) is then presented. Extensions to more complex physical situations are also discussed.
Scientific knowledge of biological processes potentially useful in fish stock predictions

Based on an extensive review of available knowledge, several sources of information have been identified as potentially useful in fish stock predictions. They refer to a variety of biological processes of importance for stock dynamics, e.g. growth, maturation and egg production as well as early and juvenile life stage survival and subsequent recruitment, for which examples are given. Environmental variables impacting these processes were derived, ranging from simple statistical exploratory analyses to complex process studies for various stocks in different sea areas. Causal relationships are understood to varying degrees and in several cases the identified variables may only be taken as proxies for processes not investigated in detail yet. Besides the explanatory power of relevant variables, their predictability and related predictive time frames are of major importance for a potential application in stock predictions. These criteria in particular may hamper implementation in the foreseeable future in several cases. However, the information may still be highly relevant for a) hindcasting stock developments that are so far not fully understood, b) defining stock projection scenarios for simulation of different fishery management strategies under varying environmental conditions and considering species interactions and c) elucidating areas of future research to further enhance our predictive capabilities.
Effects Of Street Tree Shade On Asphalt Concrete Pavement Performance

Forty-eight street segments were paired into 24 high- and low-shade pairs in Modesto, California, U.S. Field data were collected to calculate a Pavement Condition Index (PCI) and Tree Shade Index (TSI) for each segment. Statistical analyses found that greater PCI was associated with greater TSI, indicating that tree shade was partially responsible for reduced pavement fatigue cracking, rutting, shoving, and other distress. Using observed relations between PCI and TSI, an unshaded street segment required 6 slurry seals over 30 years, while an identical one planted with 12 crape myrtles (Lagerstroemia indica, 4.4 m [14 ft] crown diameter) required 5 slurry seals, and one with 6 Chinese hackberry (Celtis sinensis, 13.7 m [45 ft] crown diameter) required 2.5 slurry seals. Shade from the large hackberries was projected to save $7.13/m2 ($0.66/ft2) over the 30-year period compared to the unshaded street.
