Anti-nutritional factors and “in vitro” digestibility of leaves of Pereskia aculeata Miller

Humans need amino acids, especially the essential ones, which are obtained from the proteins ingested in the diet. With the rampant growth of the world population, it is necessary to increase the protein supplies, especially those of plant origin, which now play a major role as a food source. Leaves of ora-pronobis (Pereskia aculeata Miller) are a high quality protein source and have been used in the traditional cuisine of Minas Gerais for decades. However, it is important to analyze the anti-nutritional and/or toxic factors to consider the use of the plant leaves as an alternative source of nutrients. This work aimed to study the presence of proteic anti-nutritional factors, such as protease inhibitors and lectins, and to evaluate the “in vitro” digestibility throughout Tricine SDS-PAGE of these factors extracted from ora-pro-nobis (Pereskia aculeata Miller) leaves. The extraction of protease inhibitors and lectins from ora-pro-nobis leaves was performed in phosphate buffer. The partial purification of the fractions presenting activity of trypsin inhibitor and lectins was performed by ammonium sulfate precipitation and gel-filtration chromatography. The “in vitro” activity of the fractions with protease inhibitor and lectins, with or without heat treatment in the presence of digestive enzymes, showed that the cooking time of 1 minute was sufficient for protease inhibitors degradation. However, this time was not satisfactory for lectins, which remained resistant even after heating. This work shows that with proper cooking, ora-pro-nobis leaves can be used in the diet as a source of aminoacids
Dredging Up the Past: Lifelogging, Memory and Surveillance

The term "lifelog" refers to a comprehensive archive of an individual's quotidian existence, created with the help of pervasive computing technologies. Lifelog technologies would record and store everyday conversations, actions, and experiences of their users, enabling future replay and aiding remembrance. Products to assist lifelogging are already on the market; but the technology that will enable people fully and continuously to document their entire lives is still in the research and development phase. For generals, edgy artists and sentimental grandmothers alike, lifelogging could someday replace or complement, existing memory preservation practices. Like a traditional diary, journal or day-book, the lifelog could preserve subjectively noteworthy facts and impressions. Like an old-fashioned photo album, scrapbook or home video, it could retain images of childhood, loved-ones and travels. Like a cardboard box time capsule or filing cabinet it could store correspondence and documents. Like personal computing software, it could record communications data, keystrokes and internet trails. The lifelog could easily store data pertaining to purely biological states derived from continuous self-monitoring of, for example, heart rate, respiration, blood sugar, blood pressure and arousal. To the extent that it preserves personal experience for voluntary private consumption, electronic lifelogging looks innocent enough, as innocent as Blackberries, home movies, and snapshots in silver picture frames. But lifelogging could fuel excessive self-absorption, since users would be engaged in making multimedia presentations about themselves all the time. The availability of lifelogging technology might lead individuals to overvalue the otherwise transient details of their lives. Furthermore, the potential would be great for incivility, emotional blackmail, exploitation, prosecution and social control by government surrounding lifelog creation, content and accessibility. Existing privacy law and policy do not suggest meaningful limits on unwanted uses of lifelogging data. This parry of the costs and benefits commences a fuller discussion of lifelogging's ethical and legal implications.
Homeostasis of blood parameters and inflammatory markers analysis during bone defect healing after scaffolds implantation in mice calvaria defects

Implantation of a biomaterial can trigger an inflammatory reaction, which influences the differentiation pattern of cell populations involvedin the regenerative process, determining implant success or rejection.Five groups of chitosan (CH) – graphene oxide (GO) scaffolds were implanted in mice calvarial defects for different intervals (72 h, 2 w, 4w, 6w, 8w). The defects were randomly filled with CH or CH 0.5% -3% GO. Heparinized blood was used for the complete blood count: Red Blood Cell Count (RBC), White Blood Cell Count (WBC), Platelet Count (PLT), Hemoglobin (HGB), Hematocrit value (HCT). Blood samples were also analyzed for C-reactive protein (CRP) levels.Histopathological analysis showed that the chitosan-based scaffolds improved with 0.5-3 wt. % GO were quickly infiltrated upon implantation. Chitosan scaffolds improved with 3% GO strongly stimulated the production of TNF-α, correlated with an increase in the metabolic activity.Within the first 8 weeks, the chitosan (CH) – graphene oxide (GO) scaffolds were well tolerated by the mice and no abnormal conditions were observed. The inflammatory response was present at early stages post-implantation and it decreased after 2 weeks. Chitosan scaffolds improved with 3% GO proved to be the best tolerated biomaterial, which renders it an important candidate for the studies of bone regeneration.
O ct 2 01 8 O ( θ ) Feynman rules for quadrilinear gauge boson couplings in noncommutative standard model

Abstract We examine the electroweak gauge sector of noncommutative standard model and in particular, obtain the O (θ) Feynman rules for all quadrilinear gauge boson couplings. Surprisingly, an electroweak-chromodynamics mixing appears in the gauge sector of noncommutative standard model, where photon as well as the neutral weak boson are coupled directly to three gluons. The phenomenological perspectives of the model inW−W+ → ZZ scattering are studied and it is shown that there is a characteristic oscillatory behaviour in azimuthal distribution of scattering cross sections which can be interpreted as a direct signal of noncommutative standard model. Assuming the integrated luminosity 100 fb−1, the number of W−W+ → ZZ subprocesses are estimated for some values of noncommutative scale ΛNC at different center of mass energies and the results are compared with predictions of the standard model.
Identifiability of Normal and Normal Mixture Models with Nonignorable Missing Data

ABSTRACT Missing data problems arise in many applied research studies. They may jeopardize statistical inference of the model of interest, if the missing mechanism is nonignorable, that is, the missing mechanism depends on the missing values themselves even conditional on the observed data. With a nonignorable missing mechanism, the model of interest is often not identifiable without imposing further assumptions. We find that even if the missing mechanism has a known parametric form, the model is not identifiable without specifying a parametric outcome distribution. Although it is fundamental for valid statistical inference, identifiability under nonignorable missing mechanisms is not established for many commonly used models. In this article, we first demonstrate identifiability of the normal distribution under monotone missing mechanisms. We then extend it to the normal mixture and t mixture models with nonmonotone missing mechanisms. We discover that models under the Logistic missing mechanism are less identifiable than those under the Probit missing mechanism. We give necessary and sufficient conditions for identifiability of models under the Logistic missing mechanism, which sometimes can be checked in real data analysis. We illustrate our methods using a series of simulations, and apply them to a real-life dataset. Supplementary materials for this article are available online.
Catching Waves: Making Wave Prints to Introduce Wave Properties

a breaking ocean wave or a ripple in a pond. Physical-science courses, however, usually examine more abstract waves, such as sound and electromagnetic waves. Water waves may be more relatable to students than typical periodic motion models like springs, strings, or pendulums. This activity uses water waves as an engaging hook, provides a kinesthetic experience for students, and incorporates modeling, measurement, and mathematics into understanding wave properties. The activity also aligns with a range of practices and concepts in the Next Generation Science Standards (NGSS), the Common Core State Standards, and the Ocean Literacy Principles (Figure 1). by Lauren Kaupp, Joanna Philippoff, Kanesa Duncan Seraphin, and Matthew Lurie
Suppression of boron penetration in BF/sub 2/-implanted p-type gate MOSFET by trapping of fluorines in amorphous gate

This paper reports the use of amorphous/polysilicon gate electrode in BF/sub 2/-implanted poly-gated P-MOSFETs to suppress the boron penetration. SIMS analysis clearly illustrates that fluorine prefers to accumulate in the layer of amorphous silicon. The retardation of boron diffusion is therefore achieved by the trapping of fluorine in the amorphous layer of stacked amorphous/polysilicon (SAP) p-type gate due to a lower diffusion rate of fluorine in the amorphous silicon layer. Polysilicon depletion effect did not become more severe by introducing the amorphous silicon. In addition, gate oxide reliability is not degraded by using this gate structure. Results show that the structure is a promising gate electrode for future dual-poly gate CMOS technology development. >
Energy and poverty: myths, links, and policy issues

Bringing modern energy services to the poor is an enormous challenge. Today 1.6 billion people lack access to electricity, and 2.4 billion rely on traditional biomass fuels for cooking and heating. By 2030, if present trends continue, 1.4 billion people will still lack access to electricity-only 200 million fewer than today. And more than 2.6 billion will still rely on traditional biomass fuels-an even larger number than today.
Radio sources with ultrahigh polarization

A sample of 129 unresolved radio sources with ultrahigh linear polarization (> 30 per cent) has been selected from the NRAO VLA Sky Survey. Such high average linear polarization is unusual i n extragalactic sources. Higher resolution Australia Telescope Compact Array and Very Large Array observations confirm the high average polarization but find that most of these sources are extended. The Sloan Digital Sky Survey spectroscopy, where available, shows that the optical counterparts are elliptical galaxies with no detectable emission lines. The optical spectra, radio luminosity, linear size and spectral index of these sources are typical of radio-loud active galactic nuclei. Galaxy counts within a 1 M p c radius of the radio sources show that these highly polarized sources are in environments similar to their low polarization (< 2 per cent) counterparts. Similarly, the line-of-sight environments of the ultrahigh polarization sources are on average indistinguishable from those of the low-polarization sources. We conclude that the extraordinarily high average polarization must be due to intrinsic properties of the sources, such as an extremely ordered source magnetic field, low internal thermal plasma density or a preferential orientation of the source magnetic field perpendicular to the line of sight.
Studies relating to an electrochemically assisted coagulation for the removal of chromium from water using zinc anode

In this work, an electrochemically assisted coagulation for the removal of chromium from water has been studied using zinc as anode and galvanized iron as cathode. The effects of pH, current density, concentration of chromium, temperature, adsorption kinetics and isotherms on the removal of chromium were investigated. The results showed that the optimum removal efficiency of 96.5% was achieved at a current density of 0.2 A/dm 2 , at a pH of 7.0. First- and second-order rate equations, Elovich and intraparticle diffusion models were applied to study adsorption kinetics. The adsorption process follows second-order kinetics model with good correlation. An equilibrium isotherm was measured experimentally and the results were analyzed by the Langmuir, Freundlich and Dubinin-Redushkevich model using linearized correlation co-efficient. The Langmuir adsorption isotherm was found to fit the equilibrium data for chromium adsorption. Temperature studies showed that the adsorption was endothermic and spontaneous in nature.
Final Report : Network-Theoretic Modeling of Fluid Flow Report Title

Number of Papers published in peer-reviewed journals: Number of Papers published in non peer-reviewed journals: Final Report: Network-Theoretic Modeling of Fluid Flow Report Title A network-theoretic framework has been developed to model unsteady flows. Network analysis has been utilized to examine a wide variety of large-scale problems, including control of disease transmission, robust operation of power grids/internet, and uncovering brain functionality. The present investigation extends the network-theoretic approaches to describe the complex nonlinear behavior of unsteady fluid flows with particular focus on vortex interaction and modal energy transfer. Three canonical unsteady fluid flow problems are examined with network analysis: (1) discrete vortex dynamics, (2) modal interaction during wake formation in cylinder flow, and (3) twodimensional isotropic homogeneous turbulence. Graph theory is utilized to extract important fluid flow interactions, which enabled the development of a sparsified vortex dynamics model. The network-based approach to examine the energy transfer between modal fluid flow structures has allowed for intuitive understanding of how perturbation or control input can alter the dynamics of the global fluid flow. At last, it was revealed that two-dimensional turbulence has an underlying scale-free network structure. The findings from the present study lay out a foundation to perform further network-based characterization and control to modify the collective behavior of unsteady fluid flows.

A relação humana no cuidado de enfermagem junto ao cliente com câncer submetido à terapêutica antineoplásica

Objectives: To describe the relationship between nurses and cancer patients, in the context of chemotherapy, according to the client’s perception; to analyze nursing practice in oncology, based on human healthcare principles. Methods: This is a qualitative, exploratory and descriptive research. Ten clients undergoing chemotherapy treatment took part in the study. The “Almanac” techniques of creativity and sensitivity were associated to semi-structured interviews. Results: The subjects’ discourses revealed that nursing care is supported on principles that are proper of human relations, such as friendship, affection, attention, tolerance and solidarity. It was also highlighted that the nurse’s actions join technical and human attributes together, considering life as a fundamental ethical value in relation to human dignity as the main interaction element in healthcare. Conclusions: The results contributed for the reflection about nursing care within chemotherapy, collaborating with possible changes in the nurse’s oncology healthcare practice with this client, who already is very stigmatized by the social construction of the disease.
Cross‐cultural differences in consumer decision‐making styles

This article compares consumer decision‐making styles between Singaporeans and Australians. Utilising Hofstede’s framework, the paper argues that cultural dimensions influence consumer decision making styles. It is essential that managers understand cross‐cultural consumer decision‐making styles to make strategic decisions or effectively handle members of these nationalities. Marked differences were found between the two populations for: brand consciousness, innovativeness and overchoice confusion. The results suggest that some consumer decision‐making styles differ due to consumers’ cultural values. Managerial implications and future research directions are discussed.
Two Generalizations of the Wedderburn-Artin Theorem with Applications

We say that an $R$-module $M$ is {\it virtually simple} if $M\neq (0)$ and $N\cong M$ for every non-zero submodule $N$ of $M$, and {\it virtually semisimple} if each submodule of $M$ is isomorphic to a direct summand of $M$. We carry out a study of virtually semisimple modules and modules which are direct sums of virtually simple modules. Our theory provides two natural generalizations of the Wedderburn-Artin Theorem and an analogous to the classical Krull-Schmidt Theorem. Some applications of these theorems are indicated. For instance, it is shown that the following statements are equivalent for a ring $R$: (i) Every finitely generated left (right) $R$-modules is virtually semisimple; (ii) Every finitely generated left (right) $R$-modules is a direct sum of virtually simple modules; (iii) $R\cong\prod_{i=1}^{k} M_{n_i}(D_i)$ where $k, n_1,\ldots,n_k\in \Bbb{N}$ and each $D_i$ is a principal ideal V-domain; and {\rm (iv)} Every non-zero finitely generated left $R$-module can be written uniquely (up to isomorphism and order of the factors) in the form $ Rm_1 \oplus\ldots\oplus Rm_k$ where each $Rm_i$ is either a simple $R$-module or a left virtually simple direct summand of $R$.
Equity Portfolio Diversification: How Many Stocks are Enough? Evidence from Five Developed Markets

In this study of five developed markets we analyse the sizes of portfolios required for achieving most diversication benefits. Using daily data, we trace the year-to-year dynamic of these sizes between 1975 and 2011. We compute several widely-accepted measures of risk and use an extreme risk measure to account for black swan events. In addition to providing portfolio size recommendations for an average investor, we estimate confidence bands around central measures of risk and offer recommendations for attaining most diversification benefits 90 percent of the time instead of on average. We find that investors concerned with extreme risk can achieve diversification benefits with a relatively small number of stocks.

Striking The Balance: Privacy And Spatial Pattern Preservation In Masked Gps Data

OF THE THESIS Striking the Balance: Privacy and Spatial Pattern Preservation in Masked GPS Data by Dara E. Seidl Master of Science in Geographic Information Science San Diego State University, 2014 Volunteered location and trajectory data are increasingly collected and applied in analysis for a variety of academic fields and recreational pursuits. As access to personal location data increases, issues of privacy arise as individuals become identifiable and linked to other repositories of information. While the quality and precision of data are essential to accurate analysis, there is a tradeoff between privacy and access to data. Obfuscation of point data is a solution that aims to protect privacy and maximize preservation of spatial pattern. This study explores two methods of location obfuscation for volunteered GPS data: grid masking and random perturbation. These methods are applied to travel survey GPS data in the greater metropolitan regions of Chicago and Atlanta in the first large-scale GPS masking study of its kind.
Temporal changes in benthic assemblages on Florida Keys reefs 11 years after the 1997/1998 El Niño

Disturbances that result in the mass mortality of reef-building corals are changing the appearance of reefs worldwide. Many reefs are transitioning away from scleractinian-coral- dominated assemblages to benthic communities composed primarily of non-scleractinian taxa. This study evaluated recovery patterns of reef communities in the Florida Keys following the mortality associated with the 1997/1998 El Nino. We examined temporal trends among the 5 most spatially abundant reef taxa and stony coral species from 1999 to 2009 at 3 spatial scales, and applied a Principal Coordinate Analysis (PCoA) to determine whether changes in their cover resulted in a shift in community structure. Trends of decreasing stony coral cover were not identi- fied Keys-wide between 1999 and 2009, but 2 of the 3 habitats examined—shallow and deep for- ereefs—did show a significant decline in cover. Concomitantly, octocoral cover significantly increased Keys-wide and in all 3 habitats. The transition to octocorals was most evident on shallow forereefs, where octocoral cover significantly increased at 9 of 12 reefs and overwhelmingly influ- enced the PCoA. On deep forereefs, octocoral and sponge cover did significantly increase, but did not impart a clearly defined shift in community structure like that observed on shallow forereefs. Community composition at patch reefs was relatively consistent during the study, but the increase in octocoral cover may accelerate further following a cold-water mortality event in 2010. These results demonstrate that octocorals are emerging as the predominant benthic taxa in the Florida Keys. Although the transition to octocorals may have started long ago, their apparent resilience to present-day stressors will likely allow this shift to continue into the foreseeable future.
A reconsideration of the structure of datolite, CaBSiO4(OH)

The crystal structure of datolite, CaBSi04 (OH), has been refined by the method of least squares with allowance for anisotropic vibrations using ITO and MaRl's (1953) three-dimensional data. Refinement to an R of 12.8% with 525 reflections has led to the mean dimensions: Si-O(br) = 1.668 ::i 0.007, Si-O(per) = 1.563 ::i 0.012 A and Si-O(br)-B = 1250; bond lengths in the boron tetrahedra vary from 1.449 ::i 0.022 to 1.561 ::i 0.027 A. The Ca'" 0 links playa significant role in the structure. The Pauling-Zachariasen method of the balancing of valences gives an excellent qualitative description of the variations in the Si-O, B-O and Ca'" 0 lengths. n bonding may be the mechanism for the variations in the Si-O lengths. The structures of herderite, CaBeP04F which is isotypic with datolite, and gadolinite are also discussed on the basis of the balancing of valences.
