Evidencia de un cambio de uso de suelo anunciado. La ocupación mixta no prevista en las vialidades primarias. Zona metropolitana de Xalapa

ResumenLa lectura de la ciudad a través del tiempo permite mostrar una dinámica vinculada a los intereses vocacionales de usos de suelo; destacando el cambio generado en las vialidades principales. La investigación que se realiza sobre una vialidad primaria en un fraccionamiento, muestra el registro de los cambios experimentados en ese eje vial que originariamente fue producto de un proyecto urbano con uso generalizado habitacional, evidenciando ahora la incontrolable inercia provocada por el ímpetu comercial y de servicios coexistiendo con agonizantes viviendas esporádicas subsistentes en un paisaje lineal modificado, agregándose la conflictualidad vecinal entre la lucha por la permanencia del uso habitacional y el nuevo uso comercial. Como un referente de la creación de fraccionamientos similares, se trata de demostrar el imprevisible cambio de uso de suelo para fines comerciales, por lo que se concluye en la propuesta previsora de mezcla de usos, acorde a los actuales requerimientos urbanos.Palabras clave: Cambio de uso de suelo; corredor comercial; uso mixto; vialidad primaria; residentes. AbstractObserving the city over time allows present a dynamic linked to the vocational interests of land uses; highlighting the change generated along main roads. This research carried out on a primary road in a housing development, records the changes experienced in that road that originally was the product of an urban project with exclusively residential use, showing the uncontrollable inertia caused by the commercial activities momentum coexisting with dying sporadic dwellings subsisting in a modified linear landscape, adding a conflict between neighbours for the permanence of residential use and the new commercial uses. As a benchmark for the creation of similar developments, it demonstrates the unpredictable change in land use for commercial purposes, which is why it is proposed a mix of uses, according to current urban requirements.Key words: Land use Change; Commercial Corridors; Mixed use; Primary Roads, Residents.
Effect of Purple Sweet Potato (Ipomoea Batatas L.) on Reducing Renal Tissue Damage of House Mice (Mus Musculus L.) After Excessive Physical Exercise

Background: Heavy physical exercise can reduce blood flow and metabolism in kidney that eventually release free radicals. The free radicals can form oxydative stress and damage renal tissue. Exogenous antioxydant administration is usually recommended to minimize the renal tissue damage. This study aimed to examined the effect of purple sweet potato (Ipomoiea batatas L.) extract on renal tissue damage in mice (mus musculus L.) after heavy physical exercise.Subjects and Method: This was a randomized controlled trial with post test only control design. The study subjects included twenty four male white mice with DD Webster strain. These mice were divided into six groups. After undergoing excessive swimming exercises that lasted forteen days, purple sweet potato extract was given to the experimental group. There were three experimental groups receiving three different doses of purple sweet potato. The mice kidney was taken as sample for microscopic examination to determine the extent of tissue damage. Difference in renal tissue damage was tested by Kruskal-Wallis.Results: Microscopic examination showed statistically significant difference in tissue damage both in right (p=0.001) and left (p=0.036) kidneys, between study groups. The experimental groups showed less damaged than control group. Conclusion: Purple sweet potato (Ipomoiea batatas L) can lessen renal damage in male white mice (Mus musculus L) undergoing excessive physical exercise. Keywords: purple sweet potato (Ipomoiea batatas L), renal tissue damage mice. Corespondance: Rika Nailuvar Sinaga. Faculty of Sport Science, Medan University.

Targeted workplace incivility: The roles of belongingness, embarrassment, and power

Summary Research to date has largely been unclear about whether a single perpetrator is sufficient to instigate the well-documented negative consequences of workplace incivility. In the current research, we examine the extent to which perceived belongingness and embarrassment mediate the relationship between incivility from a single perpetrator and two important outcomes (job insecurity and somatic symptoms), and the extent to which the perpetrator's power moderates these relationships. Across two studies using different methods, we find that incidents of single perpetrator incivility are associated with target feelings of isolation and embarrassment, which in turn relate to targets' perceived job insecurity and somatic symptoms (Studies 1 and 2) both the same day and three days later (Study 2). Moreover, we find that perpetrator power moderates the relationship between incivility and embarrassment, such that targets are more embarrassed when the perpetrator is powerful. Implications for theory and practice are discussed. Copyright © 2017 John Wiley & Sons, Ltd.
CORRELATION BETWEEN BODY MASS INDEX AND BLOOD PRESSURE IN URBAN SCHOOL-GOING CHILDREN OF AGE 6–14 YEARS

Background: Obesity and hypertension (HT) have been on a rise in children. Both are associated with the increased cardiovascular disease risk and related morbidity and mortality in adulthood. Objectives: The objectives of the study were to determine the body mass index (BMI) and blood pressure (BP) of school-going urban children and to find out the correlation between BMI and BP. Materials and Methods: This study was performed on 1000 healthy school-going children (492 males and 508 females). BMI and BP were determined and recorded. Relevant statistical analysis was performed to divulge the relationship. Results: A significant (p<0.001) and positive correlation was observed between BMI and BP irrespective of gender. HT and prehypertension were observed in a higher proportion of obese and overweight study subjects. Conclusion: Control of obesity is one of the most important preventive aspects of HT in children.
Performance Analysis of FD-NOMA-Based Decentralized V2X Systems

In order to meet the requirements of massively connected devices, different quality of services (QoS), various transmit rates, and ultra-reliable and low latency communications (URLLC) in vehicle-to-everything (V2X) communications, we introduce a full duplex non-orthogonal multiple access (FD-NOMA)-based decentralized V2X system model. We, then, classify the V2X communications into two scenarios and give their exact capacity expressions. To solve the computation complicated problems of the involved exponential integral functions, we give the approximate closed-form expressions with arbitrary small errors. Numerical results indicate the validness of our derivations. Our analysis has that the accuracy of our approximate expressions is controlled by the division of <inline-formula> <tex-math notation="LaTeX">$\frac {\pi }{2}$ </tex-math></inline-formula> in the urban and crowded scenarios, and the truncation point <inline-formula> <tex-math notation="LaTeX">${T}$ </tex-math></inline-formula> in the suburban and remote scenarios. Numerical results manifest that: 1) increasing the number of V2X device, NOMA power, and Rician factor value yields a better capacity performance; 2) effect of FD-NOMA is determined by the FD self-interference and the channel noise; and 3) FD-NOMA has a better latency performance compared with other schemes.

Corpus-based Topic Derivation and Timestamp-based Popular Hashtag Prediction in Twitter

With the use of the Internet, mobile platforms, online commerce, and social media services, the footprints of human behavior can be easily recorded in the digital world, which generates data on an extremely large scale. Twitter as a big data social network becomes one of the most important sources for capturing up-to-date events happened in the world. Deriving topics from Twitter is important for various applications, such as situation awareness, market analysis, content filtering, and recommendations. However, topic derivation with high purity in Twitter is hard to achieve because tweets are limited to 140 characters. Previous works on topic derivation in Twitter suffer from low purity. In this paper, we propose corpus-based topic derivation (CTD) approach that combines a Twitter corpus and LF-LDA, which is a text processing model to identify topics and clusters of similar hashtags. We use asymmetric topic LF-LDA to obtain better purity of topics. Compared to intJNMF, a representative related work, the purity (F-measure) of our proposed CTD increases from 5.26% (27.81%) to 11.32% (34.28%) for 20 to 100 topics. We also propose a timestamp-based popular hashtags prediction (TPHP) approach by creating trending hashtags lists (THLs), which are lists of hashtags used by many users and make use of timestamps in tweets. We use the edit distance to find the difference between consecutive THLs. Then the difference can be used to calculate volatility to find how people react to real world events. Compared to Hybrid+, a representative related work, the mean average precision (MAP) of our TPHP increases by 19.45% (week-day), 15.08% (week-week) and 16.95% (month-week).
Are all data types and connectivity models created equal? Validating common connectivity approaches with dispersal data

There is enormous interest in applying connectivity modelling to resistance surfaces for identifying corridors for conservation action. However, the multiple analytical approaches used to estimate resistance surfaces and predict connectivity across resistance surfaces have not been rigorously compared, and it is unclear what methods provide the best inferences about population connectivity. Using a large empirical data set on puma (Puma concolor), we are the first to compare several of the most common approaches for estimating resistance and modelling connectivity and validate them with dispersal data.
PERFECTING YOUR PITCH

The objective of the present study was to examine the magnitude and timing of peak pelvis and thorax rotations in achieving high throwing velocities in pitching fastballs. During the preseason (Test 1 or T1) and four months later (Test 2 or T2), kinematic analysis was performed on eight elite youth pitchers throwing fastballs. Peak rotation velocities of the pelvis and thorax were determined and separation time, defined as the time between the maximal rotation velocities of the pelvis and thorax, was calculated. Peak thorax rotation velocity was not associated with throwing velocity. However, separation time appeared to be significantly and positively associated with throwing velocity. Also, the changes in separation time from T1 to T2 were significantly and positively associated with the observed increase in throwing velocity from T1 to T2. There was no significant association between the changes in pelvis or thorax peak rotation velocities from T1 to T2 and the change in throwing velocity. Results indicate that the relative timing of pelvis and thorax peak rotation velocity in pitching fastballs in baseball is likely to be a determinant of throwing velocity in skilled pitchers.
On relations between BLUPs under two transformed linear random-effects models

Abstract A general linear random-effects model with that includes both fixed and random effects and its two transformed models and are considered without making any restrictions on correlation of random effects and any full rank assumptions. Predictors of joint unknown parameter vectors under the transformed models and have different algebraic expressions and different properties in the contexts of the two transformed models. In this situation, establishing results on relations and making comparisons in between predictors under the two models are the main focuses. We first investigate relationships of best linear unbiased predictors (BLUPs) of general linear functions of fixed and random effects under the models and and construct several equalities for the BLUPs. Then, the comparison problem of covariance matrices of BLUPs under the models is considered. We derive from matrix rank and inertia formulas the necessary and sufficient conditions for variety of equalities and inequalities of covariance matrices’ comparisons under the models and
Community and International Nutrition Supplementing Lactating Women with Puréed Papaya and Grated Carrots Improved Vitamin A Status in a Placebo-Controlled Trial 1

Doubts have been raised about the effectiveness of carotene-containing foods in improving the vitamin A status of populations at risk. We investigated the effect of papaya and carrots on the vitamin A status of lactating women with 2to 12-mo-old infants in Zimbabwe. The women were randomly assigned to three supplementation groups and a placebo group, and received 6 mg of b-carotene capsules, 650 g puréed papaya, 100 g grated carrots or a placebo, daily for 60 d. All groups were given a meal containing 10 g of vegetable oil daily. Serum retinol, relative dose response, serum ferritin, hemoglobin and C-reactive protein were measured before and after the supplementation period. Mean serum retinol increased significantly after supplementation in the b-carotene group (P , 0.001), the papaya group (P , 0.001) and the carrot group (P , 0.001), but not in the placebo group (P . 0.05). The relative dose response decreased significantly (P , 0.05) in the b-carotene and papaya groups, but not in the carrot or placebo groups (P . 0.05). There was an increase in mean serum ferritin in all groups but the increase did not differ among groups. The hemoglobin increases in the b-carotene and papaya groups were greater than that in the placebo group. We conclude that puréed papaya and grated carrots can improve the vitamin A and iron nutriture of lactating women. These findings reinforce the importance of plant food–based approaches in the control of vitamin A deficiency in low income countries. J. Nutr. 131: 1497–1502,
Fully Quantum String Representation of a Wilson Loop in the Finite-Temperature 3D Yang-Mills Theory

We demonstrate the emergence of the Polchinski–Strominger term in the string representation of a Wilson loop in the confinement phase of the finite-temperature 3D Yang–Mills theory. At a temperature which is roughly twice smaller than the deconfinement critical temperature, the value of the coupling of that term becomes such that the string conformal anomaly cancels out, thereby admitting a fully quantum description of the quark–antiquark string in 3D rather than 26D.
Human Smuggling and Intentions to Migrate: Global Evidence from a Supply Shock Along Africa-to-Europe Migration Routes

Africa-to-Europe irregular migration depends heavily on human smuggling services. The demise of the Gaddafi regime in 2011 marked the end of a bilateral agreement between Italy and Libya and opened the Central Mediterranean Route for irregular border crossing. How did this remarkable increase in human smuggling services affect migration intentions in the rest of the region? This paper isolates a causal impact by exploiting the spatial dimension of the smuggling network and its change over time, which produced a heterogeneous decrease in bilateral migration distances between countries in Africa and Europe. We use this source of variation and a novel dataset of bilateral distances along irregular land and sea routes, combined with cross-country survey data on individual intentions to move from Africa to Europe between 2010 and 2012. Netting out pair- and country-by-time-specific fixed effects, we find a large negative effect of distance along smuggling routes on individual migration intentions. Shorter distances increase the willingness to migrate especially for youth, (medium) skilled individuals and those with a network abroad. The effect is stronger in origin countries not too far from Libya and with weak rule of law.
The Impact of Soda Taxes: Pass-Through, Tax Avoidance, and Nutritional Effects

The authors analyze the impact of a tax on sweetened beverages using a unique data set of prices, quantities sold, and nutritional information across several thousand taxed and untaxed beverages for a large set of stores in Philadelphia and its surrounding area. The tax is passed through at an average rate of 97%, leading to a 34% price increase. Demand in the taxed area decreases by 46% in response to the tax. Cross-shopping to stores outside of Philadelphia offsets more than half of the reduction in sales in the city and decreases the net reduction in sales of taxed beverages to only 22%. There is no significant substitution to bottled water and modest substitution to untaxed natural juices. The authors show that tax avoidance through cross-shopping severely constrains revenue generation and nutritional improvement, thus making geographic coverage an important policy decision.
A novel numerical radius upper bounds for 2 × 2 operator matrices

ABSTRACT In this paper, we establish some numerical radius inequalities for bounded linear operator defined on a complex Hilbert space. As a natural application, the existence of the all polynomial zeros is identified in a specific small disk. Moreover, we provide a refinement of an earlier numerical radius inequality due to Herzallah et al. [Numerical radius inequalities for certain operator matrices. Integr Equ Oper Theory. 2011;71:129–147] and a generalization of Shebrawi's inequality [Numerical radius inequalities for certain operator matrices II. Linear Algebra Appl. 2017;523:1–12].
Managing Harmonics in Wind Power Plants Using the Control of Wind Turbines

The integration of wind power in electricity generation introduces challenges on power quality issues. This paper proposes an algorithm to mitigate the harmonic distortion at the point of connection (PoC) of a wind power plant (WPP). Instead of opting to conventional method using passive filters to mitigate harmonics, this method only upgrades the control functions of the existing control systems of a WPP without additional investment. The mitigation algorithm performs the measurements at the PoC for a time window, which is transformed and analysed in frequency-domain. Then, it calculates the required harmonic current injections for selected wind turbine(s) to cancel the harmonics at PoC based on the frequency-dependent nodal analysis. To validate the algorithm, a generic WPP layout with multiple strings and field measurements of harmonic emission provided by Vestas Wind System A/S is used to simulate the harmonic propagation in the WPP using the MATLAB/Simulink along with PLECS Toolbox.
The Complexity of Finding S-factors in Regular Graphs

A graph G has an S-factor if there exists a spanning subgraph F of G such that for all v ∈ V : degF (v) ∈ S. The simplest example of such factor is a 1-factor, which corresponds to a perfect matching in a graph. In this paper we study the computational complexity of finding S-factors in regular graphs. Our techniques combine some classical as well as recent tools from graph theory. 2012 ACM Subject Classification Mathematics of computing → Matchings and factors; Theory of computation → Problems, reductions and completeness
Clumpy jets from black hole–massive star binaries as engines of fast radio bursts

We propose a new model of Fast Radio Bursts (FRBs) based on stellar mass black hole-massive star binaries. We argue that the inhomogeneity of the circumstellar materials or/and the time varying wind activities of the stellar companion will cause the black hole to accrete at a transient super-Eddington rate. The collision among the clumpy ejecta in the resulted jet could trigger plasma instability. As a result, the plasma in the jet will emit coherent curvature radiation. When the jet cone aims toward the observer, the apparent luminosity can be $10^{41}-10^{42}$\,erg/s. The duration of the resulted flare is $\sim$ millisecond. The high event rate of the observed non-repeating FRBs can be explained. A similar scenario in the vicinity of a supermassive black hole can be used to explain the interval distribution of the repeating source FRB121102 qualitatively.
Accuracy of automated urine dipstick test as a screening tool for proteinuria in hypertensive disorders of pregnancy

Background: Progressive proteinuria implies worsening of the condition in hypertensive disorders of pregnancy and hence its quantification guides clinician in making decision and planning treatment. The gold standard is 24 hour urine protein estimation. Urine sediment cytology, also known as ‘liquid renal biopsy’ identifies and analyses the extent of renal damage. Methods: Objectives of the study were to compare the efficacy of urine dipstick test to 24 hour urine protein estimation in detecting proteinuria in pre-eclampsic patients and to describe the findings in urine sediment examination in assessing proteinuria in above patients. Urine dipstick test and sediment cytology were performed on the urinary samples of 242 pregnant women with high BP recordings (BP>140/90 mm Hg) which were collected and tested in Department of Pathology, Government Medical College, Kottayam during the study period of 18 months. This was compared with 24 hour urine protein values (gold standard). Results: About 154 patients (63.63%) had significant proteinuria of more than 300mg/24hr. Dipstick method showed 78.57% sensitivity and 81.82% specificity for prediction of significant proteinuria. Positive predictive value and negative predictive value of urine dipstick test were 88.32% and 68.57% respectively. Urine sediment examination revealed the presence of casts only in 11.98% of study population. Conclusions: Diagnostic accuracy of automated urine dipstick test in assessing proteinuria was 79.75%. For grade 1 proteinuria, diagnostic accuracy was 79.81%, for Grade 2 it increased to 93.14% and for grade 3 & 4, accuracy was 98.68%. Urine sediment examination didn’t correlate with proteinuria and hence the extent of renal damage in preeclampsia.
