Aerated Concrete Produced Using Locally Available Raw Materials

Aerated concrete materials were developed with abundant natural materials. Aerated concrete can provide insulating qualities complemented with secondary structural attributes when used as core in sandwich composites for building construction. A hybrid binder that comprised lime and gypsum was used. Different foaming agents were considered for production of aerated concrete, including saponin that is found abundantly in different plants. Different formulations were considered, and the stability of the foam structure as well as the density and early-age compressive strength of the resulting aerated concrete were evaluated. One formulation comprising lime-gypsum binder with saponin foaming agent, with a density of 0.53 g/cm3, was further characterized through performance of thermal conductivity, split tension, flexure, elastic and shear modulus and sorptivity tests. The results pointed at the satisfactory balance of qualities provided by the aerated concrete when compared with alternative aerated concrete materials.
Sowing Resilience and Contestation in Times of Crises: The Case of Urban Gardening Movements in Barcelona

Urban gardens have been observed to multiply in response to crises. However, the meaning and motivations behind the emergence of gardening movements varies greatly over space and time. In this paper we argue that bottom up urban gardening initiatives taking place in Southern European countries in form of land occupation and communalization represent forms of resistance that enhance social cohesion and collective action in times of need. Specifically, this research examines the role of urban gardens in (i) building community resilience and (ii) articulating forms of resistance and contestation to development pressure and commodified urban lifestyles. Our research is based on data collected among 27 urban gardening initiatives in Barcelona, Spain, including 13 self-governed community gardens and 14 public gardens. Data were collected from semi-structured interviews with gardeners and with staff from the Barcelona City Council. Our results show mechanisms through which urban gardens can contribute to build resilience by nurturing social and ecological diversity, generating and transmitting local ecological knowledge, and by creating opportunities for collective action and self-organization. We further examine collectively managed gardens as urban commons that emerge as a form of resistance to the privatization of public urban space, and that offer opportunities to experiment with new models of urban lifestyles. We show how gardening initiatives can be seen to represent an emerging form of urban green commons that provides a suitable ground to ‘sow’ resilience and contestation in times of crises and socio-ecological deterioration.
Wh-questions in agrammatism: a movement deficit?

Agrammatic Broca patients suffer from a language deficit related to syntactic movement. These patients have difficulties producing and comprehending sentences derived through syntactic movement. However, patients’ performance on wh-questions shows an intriguing pattern. These constructions involve movement of the wh-word. Still, patients’ comprehension of wh-questions seems to be intact, whereas their production is severely impaired. This raises the question whether the operation of wh-movement is only impaired in patients’ production and does not affect patients’ comprehension. This question is examined in several experiments on French-speaking Broca patients. French allows the wh-word either to remain in its base position or to move. Therefore, French forms a unique environment to examine the effect of wh-movement. The results show that wh-movement affects both the production and comprehension abilities of Broca patients. These results are discussed in light of therapy studies on wh-questions in Broca’s aphasia.
Effect of ethylene diamine tetra acetic acid chelator in the presence of chromium on growth and some physiological characteristics of sunflower.

Chromium is a heavy metal toxic for plants that due extensive industrial applications over the last decade, has become a serious environmental pollution. On the other hand, chelator dissolution and absorption of metal by the plant increase and their use in phytoremediation is important. The aim of this study was to evaluate the effect of different concentrations of chromium and ethylene diamine tetra acetic acid (EDTA) chelator on sunflower (Heliantus annuus L.) through the study of growth parameters, chlorophyll, and soluble sugar amounts and Cr accumulation in plants under hydroponic culture. In order to plant sunflower were treated with different concentrations of Cr (1, 2, 4 and 6 ppm) and EDTA (0, 1 and 3 mg/L) in the medium Hoagland. The results showed that the use of chromium reduced the length of shoots and roots, and chlorophyll, while it increased soluble sugars. Addition of EDTA to the metal increased the shoot and root length and chlorophyll content while it reduced soluble sugars. According to the results, the use of chromium heavy metal in medium increased the amount of it in shoot and root. EDTA application, particularly with higher levels of chromium led to its accumulation in shoot and root. This research suggested positive role of application of EDTA in the presence of chromium heavy metal in increasing the power of phytoremediation of sunflower.
The Comparison of the Results between Single Casting and Splint in the Treatment of displaced Distal Radius Fracture in Pediatrics

Background: Distal radius fracture is one of the most prevalent fractures, which there is disagreement about its treatment and it is one of the most controversial issues of pediatric fractures. Methods: In this clinical trial, 152 children with distal radius fractures were randomly treated by the cast or splint based on the random number table. Therapeutic outputs of these patients were evaluated six weeks after treatment. Results: The results of our study show that the mean Mayo Wrist Score in the group under treatment by cast was 92.9 and in the group under treatment by splint were 90.8. Therefore, there was not a considerable difference in the physical function of the patients, statistically. According to Face Pain scale – revised and its achieved score, the two groups did not have a considerable difference from the viewpoint of wrist pain. In addition, statistically, no difference was found in the range of motion of the wrist between two groups. Therefore, the therapeutic output of the fracture without displacement or with minimal displacement of the distal radius by splint is as effective as casting. Conclusions: Considering the results of treatment by splint or cast and in addition the cost of the treatment and the complications of each, splints can be used instead of short arm cast in the fractures without displacement or with minimal displacement of the distal radius in children.
Pelvic Movement in Aging Individuals and Stroke Patients

The mobility of the lumbar spine (anteversion and retroversion) may be reflected in seated pelvic mobility. When sitting with the soles of the feet in contact with the floor, friction may restrict the flexion of the knees and, consequently, the pelvic anteversion. In general, joint mobility declines with advancing age. Lumbar spine mobility in anteversion and retroversion also decreases with advancing age. The first half of this chapter is based on a study that investigated the relationship between age and the maximum pelvic anteversion and the retroversion angles in healthy volunteers. The measurements were performed with the subject in a sitting position with free knee movement. On the other hand, the sit-to-stand movement is one of the most mechanically demanding tasks undertaken during daily activity. The sacral sitting posture, which is a characteristic posture of stroke patients, is not ideal for smoothly executing the sit-to-stand movement. Stroke patients may adopt this posture due to the need to increase sitting stability. The second half of this chapter discusses a study that investigated the relationship between the pelvic anteversion and retroversion angles and the ability of stroke patients to perform the sit-to-stand movement.
Protocol to Manage Heritage-Building Interventions Using Heritage Building Information Modelling (HBIM)

The workflow in historic architecture projects presents problems related to the lack of clarity of processes, dispersion of information and the use of outdated tools. Different heritage organisations have showed interest in innovative methods to resolve those problems and improve cultural tourism for sustainable economic development. Building Information Modelling (BIM) has emerged as a suitable computerised system for improving heritage management. Its application to historic buildings is named Historic BIM (HBIM). HBIM literature highlights the need for further research in terms of the overall processes of heritage projects, its practical implementation and a need for better cultural documentation. This work uses Design Science Research to develop a protocol to improve the workflow in heritage interdisciplinary projects. Research techniques used include documentary analysis, semi-structured interviews and focus groups. HBIM is proposed as a virtual model that will hold heritage data and will articulate processes. As a result, a simple and visual HBIM protocol was developed and applied in a real case study. The protocol was named BIMlegacy and it is divided into eight phases: building registration, determine intervention options, develop design for intervention, planning the physical intervention, physical intervention, handover, maintenance and culture dissemination. It contemplates all the stakeholders involved.
Breeding success of raft-nesting divers in Scotland

A study in 1972-78 showed that Red-throated Gavia stellata and Black-throated Divers G arctica nesting in an area of south Argyll, Scotland, where there was a shortage of island nest sites, suffered very low breeding success compared with other parts of Scotland. During 1976-80, eight artificial floating nest rafts were installed on lochs, and by 1993 breeding success had improved markedly, the productivity of Red-throated Divers being raised above the long-term average for Scotland. Nest rafts in sheltered locations were more successful and lasted longer. During 1972-78, a study of the distribution and breeding success of Red-throated Gavia stellata and Black-throated Divers G arctka in many areas of Scotland showed that the density of pairs was related to the area of suitable fishing water within a range of about 8 km of the nest site (Merrie 1978). Both species had a greater chance of success if they nested on an island (Merrie 1979), but fluctuating water levels could still cause extensive flooding of nests. A total of 114 summering pairs of Red-throated Divers produced an average of 0.33 young per pair, the average for 37 summering pairs of Black-throated Divers being 0.21. In south ArgyE, there was a shortage of island nest sites in an area with a regular population of four to six pairs of Red-throated and two of Black-throated Divers; both species suffered very low breeding success compared with other parts of Scotland. In 1976, two artificial floating nest rafts were installed at lochs in this area (Merrie 1979), although one of these disintegrated after two years. In 1979, with sponsorship from BP Petroleum Development Ltd, the lost raft was replaced and six more were installed, making a total of eight rafts, all on lochs where previous breeding attempts had been noted. In most cases, they were
Influence of Trichoderma species on seed germination in okra

Trichoderma species were evaluated for their potential regulatory effect. Okra (Abelmoschus esculentus (L) Moench) seeds were coated with spore suspension of each test species of Thichoderma supplemented with 2% of starch (w/v) as an adhesive. For each treatment, ten seeds were placed in each Petri plate and incubated at 25 °C under dark. Germination of seeds was recorded daily for 10 days. Among the three species, T. harzianum was found to be highly effective to enhance the germination percentage in okra seeds. However the species T. viridi and T. koningii were also significantly effective as compared to control. Okra seeds also gave the highest germination index values with T. harzianum which confined to better germination. Seed treatment with T. harziamun can be useful to enhance the germination percentage of okra seeds as well as reduce lose due to delayed germination. Further investigations however are required to study in vivo effect of Trichoderma spp. on germination as well as morphological and physiological characteristics in okra plant and fruit production.
Low-frequency variations of unknown origin in the Kepler δ Scuti star KIC 5988140 = HD 188774

Context. The NASA exoplanet search mission Kepler is currently providing a wealth of light curves of ultra-high quality from space. Aims. We used high-quality Kepler photometry and spectroscopic data to investigate the Kepler target and binary candidate KIC 5988140. We aim to interpret the observed variations of KIC 5988140 considering three possible scenarios: binarity, co-existence of δ Sct- and γ Dor-type oscillations, and rotational modulation caused by an asymmetric surface intensity distribution. Methods. We used the spectrum synthesis method to derive the fundamental parameters T eff , log g, [M/H], and v sin i from the newly obtained high-resolution, high S/N spectra. Frequency analyses of both the photometric and the spectroscopic data were performed. Results. The star has a spectral type of A7.5 IV-III and a metallicity slightly lower than that of the Sun. Both Fourier analyses reveal the same two dominant frequencies F 1 = 2F 2 = 0.688 and F 2 = 0.344 d −1 . We also detected in the photometry the signal of nine more, significant frequencies located in the typical range of δ Sct pulsation. The light and radial velocity curves follow a similar, stable double-wave pattern which are not exactly in anti-phase but show a relative phase shift of about 0.1 period between the moment of minimum velocity and that of maximum light. Conclusions. Such findings are incompatible with the star being a binary system. We next show that, for all possible (limit) con- figurations of a spotted surface, the predicted light-to-velocity amplitude ratio is almost two orders larger than the observed value, which pleads against rotational modulation. The same argument also invalidates the explanation in terms of pulsations of type γ Dor (i.e. hybrid pulsations). We confirm the occurrence of various independent δ Sct-type pressure modes in the Kepler light curve. With respect to the low-frequency content, however, we argue that the physical cause of the remaining light and radial velocity variations of this late A-type star remains unexplained by any of the presently considered scenarios.
Do Competing Suppliers Maximize Profits as Theory Suggests? An Empirical Evaluation

This research compares results from laboratory experiments with predictions from theory for decisions made by competing suppliers. We consider a supply chain in which a single buyer outsources the manufacture of a commodity product to suppliers not on the basis of price, but rather on service. Three different criteria on which suppliers compete are evaluated: 1) a guaranteed specific inventory fill-rate, 2) guaranteed level of base-stock, and 3) a parameter optimizing the supply chain in the buyer’s favor. Our results show that in most cases, suppliers’ decisions are significantly different than the Nash equilibrium, meaning that they do not maximize profit. We examine loss aversion as an influence that might offer an explanation for this behavior
Biometric relations of freshwater fishes of the Suaza River (Huila Department, Colombia)

The knowledge of freshwater fi shes in remote Andean mountains is scarce and restricted to changes of occurrence distribution along a specifi c gradient. The high number of endemic fi sh species requires further studies regarding their biology and their conservation status. The present study aims to estimate the length–weight, length– length, and length–girth relations for nine native freshwater fi sh species representing fi ve families (Loricariidae, Characidae, Heptapteridae, Crenuchidae, and Parodontidae): Chaetostoma thomsoni Regan, 1904; Lasiancistrus caucanus Eigenmann, 1912; Rineloricaria jubata (Boulenger, 1902); Bryconamericus huilae RománValencia, 2003; Gephyrocharax melanocheir Eigenmann, 1912; Pimelodella chagresi (Steindachner, 1876); Rhamdia guatemalensis (Quoy et Gaimard, 1824); Characidium fasciatum Reinhardt, 1867; Parodon suborbitalis Valenciennes, 1850. The fi shes were collected in the Suaza River (Huila, Colombia). These are the fi rst length–weight relations reported for all these species, mostly endemic to the Colombian Andes. The report also provides the new maximum size for four species.
The effect of sublethal concentrations of crude oil on the metabolism of Jojoba (Simmodsia chinensis) seedlings

The effect of crude oil contaminated soil at various sublethal concentrations (1%, 2%, and 3% v/w) on the metabolism of Jojoba (Simmodsia chinensis) seedlings was studied. The results showed that crude oil induced environmental stress in the seedlings. This is indicated by the increase in total carbohydrates, total proteins, amino acids and proline in shoot and a decrease in chlorophyll contents of the leaves of 85-days-old seedlings. Meanwhile, there were decreases in total carbohydrates in roots. Antioxidant enzyme activities were assessed in leaves. Increased the activities of peroxidase, ascorbate peroxidase and super oxide dismutase may contribute to limiting stress tolerance at the early stages of development in Jojoba leaves. Catalase activity was inhibited by the various concentrations except at 1%, which showed stimulation relative to the control treatment. In general, the application of inorganic fertilizers (NPK) had more or less significant changes in the metabolic activities of Jojoba at all concentrations (1-3%).
Effects of art therapy on stress and anxiety of employees

Effects of art therapy on stress and anxiety of employees The study was designed to determine if art therapy has any effect on the stress and anxiety of employees. The results demonstrated that before and after art therapy in the study group, the level of the stress indicator (cortisol) over twenty-four hours and also the state of anxiety decreased significantly (P < 0.05). The mean final stress level and situational anxiety for the study group were significantly lower (P < 0.05) than those for the control group. No significant changes were found for trait anxiety in any of the groups. These findings suggest that art therapy for employees is a preventive measure for a person to understand stress situations and to be capable to manage their anxiety, react adequately and to cope with stress, thus improving the quality of life by creative means.

Stock Prices and Resignation of Members of the Board: The Case of the Warsaw Stock Exchange

In this paper we provide an empirical analysis of announcements of resignation of board members using data which comes from the Warsaw Stock Exchange. The market reaction to this information is tested at different time horizons by means of event study methodology. The results show that market reaction is rather positive immediately before the announcement release and negative over the following six-day-period starting on the event day. A possible explanation for this phenomenon is suggested. Besides the traditional examination of abnormal return behaviour, we also check whether or not resignation announcements induce increases in the variance of stock returns over the period under consideration. It turns out that a tendency towards increased stock return volatility can be observed in the whole period prior to the announcement release.
Motion planning in real flag manifolds

Starting from Borel's description of the mod-2 cohomology of real flag manifolds, we give a minimal presentation of the cohomology ring for semi complete flag manifolds $F_{k,m}:=F(1,\ldots,1,m)$ where $1$ is repeated $k$ times. The information is used in order to estimate Farber's topological complexity of these spaces when $m$ approaches (from below) a 2-power. In particular, we get almost sharp estimates for $F_{2,2^e-1}$ which resemble the known situation for the real projective spaces $F_{1,2^e}$. Our results indicate that the agreement between the topological complexity and the immersion dimension of real projective spaces no longer holds for other flag manifolds. More interestingly, we also get corresponding results for the $s$-th (higher) topological complexity of these spaces. Actually, we prove the surprising fact that, as $s$ increases, the estimates become stronger. Indeed, we get several full computations of the higher motion planning problem of these manifolds. This property is also shown to hold for surfaces: we get a complete computation of the higher topological complexity of all closed surfaces (orientable or not). A homotopy-obstruction explanation is included for the phenomenon of having a cohomologically accessible higher topological complexity even when the regular topological complexity is not so accessible.
Classroom Procedure for Explicit Instruction in Conversational Implicature

JALT2002 AT SHIZUOKA 142 CONFERENCE PROCEEDINGS interactions according to Verschueren’s framework for two types of conversational implicature. In each situation, a variety of interpretations are considered and discussed in light of adherence or non-adherence to the maxims. The resulting procedure helps learners to understand areas of cultural difference and similarity, and promotes the development of more effective communication skills.
