Pavimentos de hormigón de la ciudad de Bahía Blanca

Se relevaron pavimentos en los diferentes ambientes geomorfologicos de la ciudad de Bahia Blanca, cubriendose una extension de 98 km 2 . Se evaluo el estado de conservacion de las losas y, donde fue posible, se tomaron muestras para realizar ensayos de porosidad, absorcion, densidad y estudios petrograficos. Se detemino que de la superficie total el 19,2% de los pavimentos son de hormigon, 36,1% flexibles, 0,6% articulados, 0,1% empedrados y el 44% esta sin pavimentar. Es frecuente observar lavado superficial, en especial en las esquinas, debido al efecto del transito y al inadecuado drenaje del agua de lluvia. Las principales causas de deterioro de las losas estanvinculadas con fallas estructurales y falta de mantenimiento de las juntas de contraccion. Por otro lado, se estudio el comportamiento hidrodinamico de la zona no saturada (ZNS) para determinar si la misma se relaciona con el estado de deterioro de los pavimentos. Se determino que la influencia de la franja capilar (FC) sobre el contenido volumetrico del suelo superficial es nula en las zonas: peniplanicie y aluvio-coluvio y nula a minima en el abanico aluvial. En la llanura de marea, la FC mantiene espesores medios de 70 cm en condiciones estaticas y de hasta 110 cm en periodos humedos, vinculado a la presencia de sedimentos finos y un acuifero freatico somero. Los niveles superficiales de la ZNS presentan altos contenidos de humedad durante la mayor parte del ano, siendo factible la influencia de las condiciones hidrodinamicas sobre el estado de las obras viales.
Goal Content for the Practice of Physical Activity

Goal content, represented by intrinsic and extrinsic goals, regulates motivation. The present study was undertaken to analyze the impact of goal content leading to physical activity in older adults (60 to 90 years), on the subjective well-being variables and to evaluate the differences between such variables according to the physical activity level practiced. Structural equation models (SEM) constituted by the principles of both regression and factorial analysis was used for analyzing the data obtained from The Goal Content for Exercise Questionnaire (GCEQ), The Positive and Negative Affect Schedule (PANAS) and The International Physical Activity Questionnaire (IPAQ-short form). A substantial positive effect of extrinsic goal content on satisfaction with life (β.24) and negative affect (β.27) and a substantial positive effect of intrinsic objectives on positive affect (β.35) were observed. Health (6.03 ± 0.74) was the most important motive whereas social recognition (3.77 ± 1.36) was the least important one. Individuals with higher physical activity had greater positive effect and satisfaction with life and lower levels of negative affect. This study is of significance in comprehending the role of physical activity and well-being among older adults.
Anti-Windup Scheme for Practical Control of Positioning Systems

Positioning systems generally need a good controller to achieve high accuracy, fast response and robustness. In addition, ease of controller design and simplicity of controller structure are very important for practical application. For satisfying these requirements, nominal characteristic trajectory following controller (NCTF) has been proposed as a practical point-to-point (PTP) positioning control. However, the effect of actuator saturation can not be completely compensated for due to the integrator windup as the plant parameters vary. This paper presents a method to improve the NCTF controller for overcoming the problem of integrator windup using simple and classical tracking anti-windup scheme. The improved NCTF controller is evaluated through simulation using a rotary positioning system. The results show that the improved NCTF controller is adequate to compensate for the effect of integrator windup. Keywords: Positioning, point-to-point, integrator windup, compensation, controller, robustness.
The curious case of Indian agriculture

This paper examines association between the cyclical component of agricultural output and rainfall in India. When the cause of food inflation is because of supply shortage driven by inadequate rainfall and poor irrigation facilities, then a contractionary monetary policy may lead to stagflation. Considering agricultural output and rainfall data from four states in India we find evidence in favor of association.
Current Status of Asian Elephants in Vietnam

Elephants have an enormous cultural and religious significance in Vietnam. Historically, images of elephants and of national heroes were often associated. During the Nguyen Dynasty from 1802 – 1945, domestic elephants graced the Royal Courts and were revered by some of Vietnam’s ethnic minorities. The Vietnam people are proud of this big animal. Images of elephants are still inherent in traditional cultures of ethnic minorities in the Central Highlands, especially in Buon Don district, Daklak province.
Creation Narratives of Mahinga Kai: Māori customary food gathering sites and practices

Mahinga kai, Mäori customary foodgathering sites and practices, emerged at the beginning of the creation narratives when the Mäori world was fi rst formed and atua roamed upon the face of the land. This paper critically evaluates the emergent discourses of mahinga kai within key Mäori creation narratives that stem from the Mäori worldview. The narratives selected for analysis were the following three creation narratives: the separation of Ranginui and Papatüänuku, the retribution of Tümatauenga and the creation of humanity. The multiple discourses that emerge from these narratives involved mahinga kai as whakapapa, whanaungatanga, tikanga with the subsequent discourse of tapu, kaitiakitanga with the subsequent discourse of mauri and mätauranga. A discursive analysis of mahinga kai in Mäori creation narratives confi rms mahinga kai as an expression of Mäori worldview and reveals a myriad of understandings.
Management strategies for the fishery of the red shrimp Aristeus antennatus in Catalonia (NE Spain)

Red shrimp (Aristeus antennatus) is the most important demersal resource in the Northwest Mediterranean. In Northeast Spain it is fished by bottom trawling and constitutes a large part of the income for local fishermen’s associations. In Palamos, the most important harbour for this fishery in the area, a management plan regulating this fishery was established in May 2013, aiming to reduce fishing effort and protect juveniles. We investigate whether the management strategy adopted in Palamos is appropriate and how it could be improved according to the stock status and fishery characteristics. For this purpose we analyze the trends of several historical series of data including fishing effort, landings, catch per unit effort (CPUE) and size frequencies in the catches. We found that fishing effort directed to this species has increased massively starting form the second half of the last century, accompanied by a marked decline in CPUE. Overfishing of the stock has been evident since 1984. Given the results obtained in this work, we consider the management strategy recently established in Palamos will be appropriate to achieve the aim of sustainability for the red shrimp fishery.

Tools for dialect syntax: the case of CORDIAL-SIN (an annotated corpus of Portuguese dialects)

This paper addresses methodological issues of concern to the study of morphosyntactic variation. While the empirical basis of dialect syntax is still a matter of elaboration, the focus will be here on the role of dialect corpora as tools for the study of linguistic variation in this particular domain. The case of CORDIAL-SIN, an annotated corpus of Portuguese dialects, will be presented along with some initial advances in Portuguese dialect syntax. Two levels of tools for the study of linguistic variation will thus be addressed here: (i) corpora as general tools for dialect syntax; and (ii) tagging and syntactic annotation within a dialect corpus as tools that ease the way how variation in morphosyntax can be studied. Section 1 introduces methodological remarks concerning the empirical ground for dialect syntax; the CORDIAL-SIN is presented in section 2; section 3 briefly illustrates how this tool has enhanced the development of Portuguese dialect syntax.
Distribution and Genotyping of Aquatic Acinetobacter baumannii Strains Isolated from the Puzi River and Its Tributaries Near Areas of Livestock Farming

Acinetobacter baumannii is an important health care-associated bacterium and a common multidrug-resistant pathogen. The use of antibiotics in the husbandry industry has raised concerns about drug-resistant A. baumannii strains, which may affect humans. This study aimed to investigate the seasonal distribution of A. baumannii in aquatic environments near areas of livestock farming. The geographic distribution, antibiotic resistance characteristic, and DNA fingerprinting genotype of A. baumannii were also studied. The results showed that environmental A. baumannii was prevalent during the summer and autumn. The hotspots for A. baumannii were found at the sampling sites of livestock wastewater channels (21.4%; 3/14) and the tributaries adjacent to livestock farms (15.4%; 2/13). The prevalence of A. baumannii at these locations was significantly higher than those adjacent to the Puzi River. Multidrug-resistant strain of A. baumannii was not found in this study, with only one strain (5%; 1/20) being resistant to tetracycline. Of the isolates that were obtained, 10% (2/20) and 20% (4/20) were found to be intermediately resistant to tetracycline and sulphamethoxazole/trimethoprim, respectively. The genotyping patterns and clustering analysis indicated that enterobacterial repetitive intergenic consensus sequence polymerase chain reaction (ERIC-PCR) differentiated A. baumannii strains effectively. There were two major clusters that could then be subtyped into 20 A. baumannii strains with 15 profiles. The A. baumannii strains that were isolated from upstream of the Puzi River and livestock wastewater channels were composed of Cluster I. Cluster II only contained isolates from downstream of the Puzi River area. Furthermore, isolates from adjacent sites were shown to have identical profiles (100%). These results suggest that A. baumannii may have spread through free-flowing water in this study. Therefore, we propose that livestock wastewater is one of the sources that contribute to A. baumannii pollution in water bodies. In summary, continuous monitoring of antibiotic pollution in livestock wastewater is required.
Magnetic resonance imaging of the static magnetic fi eld distortion caused by magnetic nanoparticles : Simulation and experimental veri fi cation

Magnetic nanoparticles are widely used as a contrast agent in magnetic resonance imaging (MRI). Nanoparticles in contrast agents possess a magnetic moment which generates local inhomogeneities in the static magnetic field of the MR scanner. These inhomogeneities cause a rapid loss of phase coherence which leads to the fast decay of the MR signal and thus produce a negative contrast in MR images. This article is focused on the interaction of magnetic nanoparticles aligned in a thin layer with the external homogeneous magnetic field, which changes the uniform distribution of magnetic nanoparticles in the carrier liquid. The goal of this study is to investigate the influence of the arrangement of magnetic nanoparticles on the final image contrast during MRI. & 2014 Elsevier B.V. All rights reserved.

Method for identification the effects of dynamic overload affecting the people, which may occur in the emergency state of suspended monorail is presented in the paper. The braking curve using MBS (Multi-Body System) simulation was determined. For this purpose a computational model (MBS) of suspended monorail was developed and two different variants of numerical calculations were carried out. An algorithm of conducting numerical simulations to assess the effects of dynamic overload acting on the suspended monorails’ users is also posted in the paper. An example of computational model FEM (Finite Element Method) composed of technical mean and the anthropometrical model ATB (Articulated Total Body) is shown. The simulation results are presented: graph of HIC (Head Injury Criterion) parameter and successive phases of dislocation of ATB model. Generator of computational models for safety criterion, which enables preparation of input data and remote starting the simulation, is proposed.
Relative humidity-dependent viscosities of isoprene-derived secondary organic material and atmospheric implications for isoprene-dominant forests

Abstract. Oxidation of isoprene is an important source of secondary organic material (SOM) in atmospheric particles, especially in areas such as the Amazon Basin. Information on the viscosities, diffusion rates, and mixing times within isoprene-derived SOM is needed for accurate predictions of air quality, visibility, and climate. Currently, however, this information is not available. Using a bead-mobility technique and a poke-flow technique combined with fluid simulations, the relative humidity (RH)-dependent viscosities of SOM produced from isoprene photo-oxidation were quantified for 20–60 μm particles at 295 ± 1 K. From 84.5 to 0% RH, the viscosities for isoprene-derived SOM varied from ~ 2 × 10−1 to ~ 3 × 105 Pa s, implying that isoprene-derived SOM ranges from a liquid to a semisolid over this RH range. These viscosities correspond to diffusion coefficients of ~ 2 × 10−8 to ~ 2 × 10−14 cm2 s−1 for large organic molecules that follow the Stokes–Einstein relation. Based on the diffusion coefficients, the mixing time of large organic molecules within 200 nm isoprene-derived SOM particles ranges from approximately 0.1 h to less than 1 s. To illustrate the atmospheric implications of this study's results, the Amazon Basin is used as a case study for an isoprene-dominant forest. Considering the RH and temperature range observed in the Amazon Basin and with some assumptions about the dominant chemical compositions of SOM particles in the region, it is likely that SOM particles in this area are liquid and reach equilibrium with large gas-phase organic molecules on short time scales, less than or equal to approximately 0.1 h.
Adsorption-solubility equilibria and speciation of Pb, Cd, and Zn in a savanna soil

Emission of contaminants into the environment is a common feature of industrialization. The danger of these substances has generated interest in their solubility and speciation. In this study, the nature of adsorption, solubility and speciation of Pb, Cd and Zn under high levels of accumulation were evaluated through a model sorption-solubility experiment. Equilibrium concentrations of metals and other soil characteristics were used as input parameters in a metal speciation model. The solubility controls of metal activities were evaluated through the use of activity/stability diagrams. The solubility of Pb, Cd and Zn was enhanced between pH 4.8 and 6.6. Increased solubility at this pH range indicates higher bioavailability and toxicity. Speciation results showed a predominance of free metal species in the soil solution. The activity diagrams used to test the stability of possible mineral bearing compounds in the soils did not show any particular solid phase as possible control of the activities of Pb, Cd and Zn in solution. This suggests that solubility controls might be due to the formation of metastable minerals which are not well crystallized.
Motivating Energy Conservation among Non-rate Paying Households with Feedback and Social Nudges: A Cautionary Tale

Non-price interventions have been shown to be valuable instruments in reducing energy use among rate paying customers, but their effect on non-ratepayers have received less attention. This study uses a randomized controlled trial research design to examine the effect of feedback and a social nudge on energy consumption of non-rate paying households. Empirical findings are based on 218,387 hourly observations from 62 households gathered over a period of 21 weeks. Our results suggest that neither feedback on energy use or a social nudge in the form of peer comparison are effective instruments to reduce the energy usage of non-rate paying households. The average treatment effect masks heterogeneous effects among households that are low and high users of energy in the pre-treatment period: both interventions increase energy use for high users while feedback decreases usage among low users. The effect of the social nudge among low users depends on their relative usage in the previous period, with above-average users decreasing consumption, and vice versa. We discuss these empirical results in the context of a model of utility that incorporates moral utility and preferences for conformity.
Geotechnical Challenges with Malaysian Peat

Malaysian peat is a tropical peat (Andriesse, 1988). This peat has unique characteristics, which makes it significantly different from other peat. In its natural state, this soil is normally dark reddish brown to black in colour and consists of partly decomposed leaves, branches, twigs and tree trunks with a low mineral content. These are formed through accumulation of disintegrated plant remains, which have been preserved under conditions of incomplete aeration and high water content. Hobbs (1986) stated that it was important to include and recognise the peat by not only its morphology but also by its basic engineering properties. The “special” characteristics for this soil are a high water content (>200%), high compressibility, high organic content (>75%), low shear strength (5-20kPa) and low bearing capacity (<8 kN/m2). These geotechnical characteristics make any form of construction on this soil very challenging in Malaysia (Zainorabidin and Bakar, 2003). This paper presents an overview of previous research carried out on peat soils (Mutalib et al, 1991; Jarrett, 1997; Bujang, 2004; Zainorabidin and Bakar, 2003). Edil (2003) demonstrated the variability of the peat properties even within a single sample, leading to it being far from homogeneous, which is a prime requirement in engineering soil mechanics. The compressibility of the individual peat particles invalidates one of the prime assumptions of particle incompressibility adopted in soil mechanics This paper also discusses the challenges that geotechnical engineers have faced in Malaysia when designing and managing construction on this soil.

In this paper, it takes the overview of O2O business model as the starting point, with the analysis on the application of electronic commerce in agricultural products market, as well as the analysis on the online and offline interactive marketing, discussing the framework of O2O system, which is based on the integration of online and offline agricultural products, so as to solve the problems existed in the circulation of agricultural products.
From Waste to Employment Opportunities and Wealth Creation: A CaseStudy of Utilization of Livestock By-Products in Hargeisa, Somaliland

The objective of the study was to establish the involvement of vulnerable women and youths in innovative livestock by-products value addition to create alternative employment opportunities and diversify wealth creation livelihood activities through DFID funded SEED programme being implemented by FAO Somalia in the security fragile state of Somaliland that has few options of formal employment opportunities. The study focused on the processes and achievements of the SEED programme towards deriving maximum benefits from livestock by-products instead of concentrating on meat production and consumption only. During the programme intervention, an initial forty (40) beneficiaries of various trade skills and academic levels were selected through SOMDA for capacity development with Competency Based Training (CBT) skills. One of the primary advantages of CBT was that it focused on the success of each participant. The training focused on each trainee attaining a small number of specific and job-related competencies in bone-craft trinkets and laundry soap production. By the end of SEED phase I, the intervention created a total of 120 direct jobs who were involved in soap and bone-crafts production giving the impetus of making full use of the meat value chain and creating a viable source of employment and income for women and youths in Somaliland contributing to increased Somali economy from the main lifeline of Somalia population that is anchored on livestock production and trade.
Women in Politics: A New Instrument for Studying the Impact of Education on Growth

This paper tests the growth model of distance to the technological frontier, which states that the closer an economy is to the frontier, the higher the relative importance of innovation relative to imitation as a source of productivity growth. Hence, an economy closer to the technological frontier should invest more in skilled labor since innovation is a skill-intensive activity. I use the proportion of female legislators as an instrument for skilled labor, in contrast to Vandenbussche, Aghion, and Meghir (2006) who used lagged educational expenditures. The results with the new instrument are consistent with the theoretical prediction and the previous results of Vandenbussche, Aghion, and Meghir (2006).
