Antioxidant content in guava (Psidium guajava) and araçá (Psidium spp.) germplasm from different Brazilian regions

Guava (Psidium guajava) and araçá (Psidium spp.) plants are important for the Brazilian economy, as their fruit is both accepted by the consumers, and makes a beneficial contribution to the human diet thanks to their content in vitamin C, carotenoids and phenolic compounds. Here, we report the content in the fruit of free ascorbic acid, lycopene, β-carotene, flavonoids and phenolic compounds, and the total antioxidant activity present in a collection of guava and araçá accessions curated at the Embrapa Semiarido germplasm bank. Guava fruits with a red-coloured pulp flesh contained a significant amount of carotenoids, especially lycopene, and a high concentration of phenolic compounds. These compounds were largely responsible for the antioxidant activity of the araçá accessions. Among the guava accessions, phenolic compounds were also responsible for the antioxidant activity. High levels of free ascorbic acid were present in most accessions. In both guava and araçá, there is substantial potential to develop cultivars with a good level of consumer acceptability.
Spatial patterns of woody plant regeneration in two California Central Valley floodplain forests

Because flooding is a frequent and predictable disturbance in riparian plant communities, many studies have focused on the influence of abiotic factors on woody plant regeneration in these communities. However, biotic factors may also affect patterns of plant regeneration in riparian communities, especially in portions of the floodplain subject to less frequent and intense flood disturbances. I examined the correlation between woody seedlings and groundcover and overstory composition at two sites with low flood recurrence intervals in the floodplain of the Sacramento River, California. Seedlings were distributed nonrandomly among both groundcover and overstory classes at both study sites. Seedlings of all species examined were negatively spatially associated with forb and liana cover and positively spatially associated with litter-covered substrate. Additionally, seedling densities were lower in forb and liana cover than in more open groundcover types for several species as well as all species combined. Seedling distribution among overstory cover types was strongly species specific. My results imply that plant-plant interactions may constrain the regeneration o f woody species at these sites.
Cyber Notary System in the Order of Norms in Indonesia and Australia (Comparative Study in Notary Service Improvement Strategies)

The purpose of this study was to determine the setting of norms about the Cyber ​​Notary system in Indonesia and Australia and to find out the differences and similarities in the Cyber ​​Notary regulatory system in both countries. This study uses a type of normative research; the theories used in this study are the theory of justice, the theory of legal certainty and comparative law theory. The approach method used is the conceptual approach, the legislative approach, and the comparative approach. Analysis of this study, using comparative analysis is to collect material according to the appropriate legal material about the problem being studied, and then compare it. Based on the results of the study that, the regulation of the norms regarding the Cyber ​​Notary system in Indonesia is in the Law, namely a. Law No. 2 of 2014 concerning changes to Law No. 30 of 2004 concerning Notary Position. b. Law No. 11 of 2008 concerning Information and Electronic Transactions (ITE Law), c. Law No 40 of 2007 concerning Limited Liability Companies, and for Australian Countries, how many Cyber ​​Notary Arrangements are explained in the 1999 / Electronic Electronic Transaction Act Transactions Act 1999 / ETA (Australia). The difference lies in Indonesia having its own rules in which there is clearly stated authority in carrying out the profession of notaries including in connection with the identification of transactions electronically (Cyber ​​Notary), while Australia does not have its own specific rules that explain explicitly the authority of notaries in serving Cyber ​​systems. Notary, because the service mechanism is part of the form of electronic transactions that are regulated in the 1999 Electronic Transaction Act / Electronic Transaction Act 1999 / ETA. The equation is seen in the Function, the Cyber ​​Notary System is equally a government regulation in the form of public servants quickly, concisely, and has the value of legal protection on all parties. in Indonesia with the Registration of Online Companies, through the Legal Entity Administration System or abbreviated as SABH, and in Australia with the e-apostille system. In terms of its objectives, namely the implementation of the Cyber ​​Notary system in the two countries, which are both aimed at raising the potential of the economy and trade inside and outside the country.
Manufacturing Double Curved Precast Concrete Panels using a Flexible Mould

Free form architecture with complex geometry brings along new challenges for manufacturers of building components. This paper describes the application of structural mechanics to predict the behaviour of an elastic mould surface, used as formwork for the manufacturing of double curved panels in precast concrete. Results are presented of laboratory experiments with a formwork to validate the model. The authors demonstrate that the model together with the mould prototype enable a flexible yet straightforward production method for curved concrete products that is applicable in many free form architecture projects nowadays.
Infrared thermography for laser-based powder bed fusion additive manufacturing processes

Additive manufacturing (AM) has the potential to revolutionize discrete part manufacturing, but improvements in processing of metallic materials are necessary before AM will see widespread adoption. A better understanding of AM processes, resulting from physics-based modeling as well as direct process metrology, will form the basis for these improvements. Infrared (IR) thermography of AM processes can provide direct process metrology, as well as data necessary for the verification of physics-based models. We review selected works examining how IR thermography was implemented and used in various powder-bed AM processes. This previous work, as well as significant experience at the National Institute of Standards and Technology in temperature measurement and IR thermography for machining processes, shapes our own research in AM process metrology with IR thermography. We discuss our experimental design, as well as plans for future IR measurements of a laser-based powder bed fusion AM process.
Asymmetry and Persistence of Energy Price Volatility

Th is study estimates and compares the asymmetry and persistence of volatility of crude oil, natural gas and coal- three main sources of energy. This study also evaluates the effect of recent Global Financial Crisis (GFC) on the return and volatility of these energy prices. Threshold GA RCH (TGA RCH) and fract ionally integrated GA RCH (FIGA RCH) model are employed to facilitate the study. The estimated results show that coal return volatility exhib its strong mean reversion whereas crude oil and natural gas return volatility endures shocks for relatively higher period. The estimated results also confirm that volatility of crude oil and natural gas increases after positive shocks in prices.
A review, map and research agenda

Purpose – The purpose of this paper is to re-map the neglected phenomenon of organisational misbehaviour (misbehaviour) by reflecting the many approaches taken on this emergent field of study, and articulate a revised research agenda. Design/methodology/approach – Both preceding and recent empirical and theoretical research papers are discussed and possible overlap and convergence of findings are examined. The discussions mainly surround studies from industrial sociology and organisational behaviour, yet studies from industrial relations and gender studies are also considered. From the re-assessment, a revised map and research agenda for misbehaviour is produced. Findings – More research should be directed towards humour and its uses in contemporary organisations, why managers break the rules, the internet as a tool and framework for defiant activities, informal and hidden employee identities as a framework for self-organised misbehaviour, functional misbehaviour and informal strategies used by employees to survive work. Further work is required to unify the field and suggestions are made on how this may be achieved. Research limitations/implications – The paper is based on a re-assessment of the extant literature and the findings reflect the broadly problematic matter of reconciling incongruous paradigms. Practical implications – The paper puts forward a revised and updated map of organisational misbehaviour. It also offers insights which managers can use to deal with a broad range of misbehaviour conducted within and outwith the workplace. Originality/value – The paper provides a new map that goes beyond previous articulations of misbehaviour. The revised research agenda attempts to guide future research on the subject of misbehaviour in a more balanced direction.
The Effect of Polylactic Acid Packaging Modified with Clay Nanoparticles on Quality and Shelf life of Mushroom

One of the newest technologies for storing agricultural products is the biodegradable packagingmethod, in which certain materials are utilized on a nano scale. Edible mushroom is a nutritious agriculturalproduct which can be considered a food source as well as having medicinal applications while having a shortshelf life after harvesting. In this study, the mushroom was packaged in polylactic acid packages containingnanoparticles of clay and the effect of the packaging on the quality characteristics and shelf life of mushroomwere determined. Aiming at determining the most optimal conditions for the packaging of the mushroom, theeffects of the weight percent of nano clay (0, 3 and 6 wt%), time of storage (4, 8 and 12 day), and three differenttemperatures (4, 14, and 24 0C) on the quality characteristics and the shelf life of mushroom have beeninvestigated. Different regression models were adopted to correlate the empirical results of dependent variables,and through statistical analyses the most reliable regression model was selected.
Bayesian Reconstruction of Missing Observations

We focus on an interpolation method referred to Bayesian reconstruction in this paper. Whereas in standard interpolation methods missing data are interpolated deterministically, in Bayesian reconstruction, missing data are interpolated probabilistically using a Bayesian treatment. In this paper, we address the framework of Bayesian reconstruction and its application to the traffic data reconstruction problem in the field of traffic engineering. In the latter part of this paper, we describe the evaluation of the statistical performance of our Bayesian traffic reconstruction model using a statistical mechanical approach and clarify its statistical behavior.
Yeast as a Versatile Tool in Biotechnology

Yeasts represent a very diverse group of microorganisms, and even strains that are clas- sified as the same species often show a high level of genetic divergence. Yeasts biodi versity is closely related to their applicability. Biotechnological importance of yeast is almost immeasurable. For centuries, people have exploited its enzymatic potential to produce fermented food as bread or alcoholic beverages. Admittedly, yeasts application was initially instinctual, but with science and technology development, these microor ganisms got the object of thorough scientific investigations. It must be recognized that yeast represents an excellent scientific model because of its eukaryotic origin and knowl edge of genetics of yeast cells as well as metabolism examined in detail. In 1996, the genome of baker yeast Saccharomyces cerevisiae has been elucidated, what opened the opportunity for the global study of the expression and functioning of the eukaryotic genome. Also, currently, an international team is working on the synthesis of the 16 yeast chromosomes by synthetic biology tools, and the results are expected till the end of the year. Nowadays, yeast is regarded as a versatile tool for biotechnological purposes.

A Study on Knowledge Gain and Retention when Using Multimedia Learning Materials of Different Quality

The usage of multimedia has proven to foster meaningful learning, but not every multimedia resource will necessarily contribute to the teaching-learning process. Since for the development of multimedia learning materials (MLMs) additional time and effort is required for everyone involved in the development process to pay proper attention to its quality in order to achieve desired learning effects. The paper deals with issues regarding the quality of multimedia learning materials (MLMs) as well as the relationship between MLM quality and knowledge retention. The results of an experimental study that involves low-quality and high-quality MLMs for two different topics and their effects on knowledge gain and retention of the polytechnic school students are presented. For the purpose of the research the LORI assessment tool was used to evaluate the quality of MLMs. The analysis of research data shows that MLMs developed according to the principles of multimedia learning and principles for reducing cognitive load were perceived as being of higher quality than those that were not developed using multimedia principles. Furthermore, the students’ usage of high-quality MLMs during treatment resulted in better knowledge acquisition and retention indicated by significantly higher scores in the three knowledge assessments.
A New Scheme for Keypoint Detection and Description

The keypoint detection and its description are two critical aspects of local keypoints matching which is vital in some computer vision and pattern recognition applications. This paper presents a new scale-invariant and rotation-invariant detector and descriptor, coined, respectively, DDoG and FBRK. At first the Hilbert curve scanning is applied to converting a two-dimensional (2D) digital image into a one-dimensional (1D) gray-level sequence. Then, based on the 1D image sequence, an approximation of DoG detector using second-order difference-of-Gaussian function is proposed. Finally, a new fast binary ratio-based keypoint descriptor is proposed. That is achieved by using the ratio-relationships of the keypoint pixel value with other pixel of values around the keypoint in scale space. Experimental results show that the proposed methods can be computed much faster and approximate or even outperform the existing methods with respect to performance.
Composition of zooplankton assemblages along the Zagyva River

The species composition, longitudinal distribution and seasonal dynamics of zooplankton were studied in the Zagyva River, Hungary. A total of 108 taxa was recorded from which 61 were new for the river. Rotatoria was the most abundant group, microcrustaceans were less important, only nauplii and copepodites were represented in similar individual numbers. Frequent species included Anuraeopsis fissa, Pompholyx spp. , Keratella cochlearis, Brachionus angularis, Bdelloida sp. , Bosmina longirostris. Dominance of cosmopolitan species was observed both in the river and its reservoir, and species characteristic of eutrophic waters were of major importance in the latter. There was a downstream decrease in zooplankton densities, which was explained by modified conditions. The relatively large number of individuals in autumn months, and the characteristic large number of individuals in the upper section contrasted general findings of potamoplankton dynamics. On the basis of the species abundance matrix, three river sections can be distinguished (upper, middle, lower section). Due to waste water discharges - received from the Tarjan Stream - we found extremely high number of individuals and the lowest diversity at the sampling site Nagybatony (148 rkm).

The Patent Controversy in the Nineteenth Century

T HE patent system has lately been subjected to investigations by committees of Congress, and reforms have been proposed to meet some of the most serious criticisms. In recent publications commenting on these discussions it has been suggested that opposition to the patent system is a new development. A writer of a "history of the patent monopoly" asserted that "there never has been, until the present time, any criticism of this type of exclusive privilege,"1 and he attributed the allegedly new attitude to "modern witch-hunters," hungry aspirants to public office," and, by innuendo, to enemies of all private property.2 In actual fact, the controversy about the patent of invention is very old, and the chief opponents of the system have been among the chief proponents of free enterprise. Measured by number of publications and by its political repercussions chiefly in England, France, Germany, Holland, and Switzerland the controversy was at its height between i850 and i875. The opposition demanded not merely reform but abolition of the patent system. And for a few years it looked as if the abolitionist movement was going to be victorious.3 The patent controversy, as most seesaw battles, attracted at the time the widest public interest; frequent reports appeared in the daily press and in weekly magazines. That the whole story was later forgotten and now seems to be unknown even to experts in this field is probably due to
Face-to-Face or Cyberspace? Choosing the Internet as an Intermediary in the Israeli Travel Market

Existing studies of the trend towards electronic provision of travel services tend to be highly bifurcated. They focus either on the supply-side characteristics of this change (new technologies and mediation platforms) or on the demand-side attributes, such as the socio-economic profile of the Internet user and attitudes towards electronic purchasing in the travel market. The latter approach, however, can lead to sample selectivity bias and misleading parameter estimates. It fails to recognize that actual Internet travel purchases are observable only for individuals who have made the prior decision to use the Internet as a market intermediary. This paper addresses this drawback by modelling the decision to purchase travel products on the Internet in a bivariate probit framework. The choice of travel service intermediary, travel agent (face-to-face) or Internet (cyberspace), is determined by the joint probabilities of general Internet purchasing and specific Internet travel purchasing. Using unique survey evidence of actual Internet transactions, the discrepancies between preferences for Internet travel purchasing and actual travel purchases are highlighted. The results suggest that demand for the latter is more closely related to previous Internet purchasing experience than to the socio-economic attributes of the purchaser.
Identification of Internet Usage and Dependency Level of Physical Education and Sport Teaching Students

The excessive internet usage that interrupts social relations, physical characteristics and mental conditions of individuals is called as internet addiction. At the previous studies, it is reported that university students are at risk of Internet addiction due to their uncontrolled lives without families and killing their time surfing the internet. The objective of this study is to identify the addiction level of university students’ internet usage within the framework of some variables. A total of 463 students, 194 girls and 269 boys, who study at different 7 Departments of Physical Education and Sport Teaching within School of Physical Education and Sports and Faculties of Sport Sciences, attended this study in 2016-2017 Academic Years. “Personal Information Form” is used to determine the internet addiction of students “Internet Addiction Scale” developed by Young (1998) and to determine the demographic features and the data regarding the internet usage. In this study, the risk average for internet addiction of students is determined 2.55. It has been observed that the individuals who addict the internet constitute 3.9% of my samples. It is confirmed that internet addiction of male students is considerably higher than female students. It is ascertained that students who have Internet and a social media account are under higher risk of internet addiction. It has been emerged that there is no significant relation between the age/ monthly income of the family and the internet addiction level.
