Utilization of the Alkaline White Mud as Cement-Based Materials for the Production of Cement

The effects of using alkaline white mud as substitutes for cement property in the process of clinker burning were investigated in this paper. Samples were prepared with adding 0.5-5.0% of alkaline white mud as substitutes for unit raw meal and then these mixtures were burned at 1450°C for 2 hrs. The results showed that the compressive strength and flexibility strength of the pastes were a little better than the plain sample. The concentrations of MgO, SO3 and chloride ions in clinkers were far below the limits in the standards when the addition of alkaline white mud was below the content of 5.0%. The Results also showed that the concentrations of free lime were in a growing tendency with the increasing of alkaline white mud. Moreover, the addition of AWM in raw meal increased the content of C3S phase in the clinker, something leading the increase of the setting times and enhances the strengths of the cement pastes in the early curing ages.
Impact of Job Characteristics on Employees Emotions & Work-Related Outcomes in Pakistan

The impact of job characteristics on organizational success and its members’ work attitudes and behaviors is not new in the field of organizational behavior. However, the empirical work on gauging the influence of job features on affective states of employees and its subsequent impact on work outcomes is rather marginal. The study intends to validate the relationship amid job characteristics, employees’ affective states and their attitudes and behaviors. The five core job dimensions of Job Characteristics Model i.e. skill variety, task identity, task significance, autonomy and feedback have been adopted to determine the characteristics of the job undertaken. Affective Events Theory has been used to examine the hypothesized relationships between the antecedent (i.e. job characteristics) and consequents of affective experiences (i.e. attitudes: job satisfaction, commitment to organization; and behaviors: organizational citizenship behavior and counterproductive work behavior) of the employees while at work. Regression analysis of the survey data from 215 organizational members from private and public organizations in Pakistan, identified the significant impact of job autonomy, skill variety and task significance on the affective states of employees impacting their satisfaction level towards the job. However, the emotional experiences due to job characteristics showed no influence on employee’s commitment towards the organization as well their citizenship and counterproductive work behavior.
Influence of mixing methods on the properties of high density polyethylene nanocomposites with different carbon nanoparticles

In this paper, nanocomposites with multiwalled carbon nanotubes (MWCNT) or graphene nanosheets were prepared using a high density polyethylene (HDPE) matrix. Two different processes were employed: a solution method and a melt mixing method. The crystallinity index of the HDPE showed similar levels in nanocomposites after the addition of carbon nanotubes. It can be seen that the preparation process modified the degree of crystallinity of the HDPE matrix with graphene nanosheets. Nanocomposites prepared by the solution method showed a decrease in the crystallinity index. The addition of carbon nanotubes led to an increase of YoungÂ´s Modulus with an increase in the MWCNT quantity, regardless of the preparation process used, with a 22.8 % increase for composites with 0.5 wt% of CNTs. The nanocomposites with graphene nanosheets exhibited a different behavior with each mixing method. Nanocomposites prepared by the solution method showed a higher YoungÂ´s Modulus than those prepared by melt mixing. Results of transmission electronic microscopy and field emission scanning electronic microscopy indicated homogeneous dispersion for carbon nanotubes in melt mixing. Graphene nanocomposites showed some agglomerates, with smaller platelets in the nanocomposites prepared by solution mixing compared to that prepared by the melt mixing. Keywords: nanocomposites, high density polyethylene, graphene, carbon nanotube, mixing methods
Distribution and breeding biology of the red-fronted macaw

ABsTRAC-r. -The Red-fronted Macaw (Ara rubrogenys), endemic to Bolivia with a restricted range and a small population, was observed regularly between late December 1981 and early March 1982. Individuals were found at elevations between 1300 and 2400 m in the arid intermontane valleys of south central Bolivia in southeastern Cochabamba and western Santa Cruz departments, where they had been reported previously, and in northwestern Chuquisaca and northeastern Potosi departments. Seven nests were located in cavities in cliffs 15 to 50 m tall. Courtship and incubation activities took place during December and January. Nestlings were present during February and March. Received 10 Dec. 1990, accepted 28 March 1991.
Can theory disempower? Making space for agency in theories of Indigenous issues

Aboriginal and Torres Strait Islander people are often presented by the media and academics as marginalised, dispossessed, and downtrodden. Historical narratives and statistics are used to strengthen this position. While this historical and ongoing reality must be acknowledged in order for meaningful reconciliation to occur, it must not come at the expense of Indigenous agency. Many Aboriginal and Torres Strait Islander people exercise considerable control over their own circumstances. Activists and other advocates for Aboriginal rights exercise agency "as resistance", demanding changes to current structures. Other people engage in agency "as project", adopting different tactics to achieve their goals. These tactics are often productive – creating Aboriginal services, for example – but agency is sometimes expressed in more 'repugnant' ways, such as crime or riots, such as the event following the Palm Island death in custody in 2004. This paper argues that a sociology of Indigenous issues must incorporate agency to ensure that our theories do not deny Aboriginal people a voice. Aboriginal people have the ability to make changes and resist norms, and this should not be ignored in favour of structural causes of dysfunction. Drawing on the work of social movement theory, supplemented by Giddens, Ortner, Cowlishaw, and Scott, I explore the "two faces" of agency and suggest that research which privileges agency should be a key feature in a sociology of Indigenous issues.
Kinematics of Magnetic Bright Features in the Solar Photosphere

Convective flows are known as the prime means of transporting magnetic fields on the solar surface. Thus, small magnetic structures are good tracers of turbulent flows. We study the migration and dispersal of magnetic bright features (MBFs) in intergranular areas observed at high spatial resolution with Sunrise/IMaX. We describe the flux dispersal of individual MBFs as a diffusion process whose parameters are computed for various areas in the quiet-Sun and the vicinity of active regions from seeing-free data. We find that magnetic concentrations are best described as random walkers close to network areas (diffusion index, ), travelers with constant speeds over a supergranule ( ), and decelerating movers in the vicinity of flux emergence and/or within active regions ( ). The three types of regions host MBFs with mean diffusion coefficients of 130 km2 s−1, 80–90 km2 s−1, and 25–70 km2 s−1, respectively. The MBFs in these three types of regions are found to display a distinct kinematic behavior at a confidence level in excess of 95%.
Space Invaders: The Negotiation of Teenage Boundaries through the Mobile Phone

Drawing on interview data, this paper explores the area of child/parent negotiation. Specifically, we examine the increasing significance of the mobile phone in the way teenagers negotiate spatial boundaries with their parents. Utilising theories of time and space, especially Giddens’ concept of ‘distanciation’, we show how parents and their children use the mobile phone as a tool for negotiating curfews in public space, thus extending household discussion and negotiation outside of the home. We point out that parents are using the mobile phone to enter their children's time and space as an ‘absent Other’, and see this as a means of extending parental authority and control. Children, conversely, see themselves gaining a degree of empowerment from the mobile phone, as parents are more lenient with curfews if they posses one. The mobile phone, then, has become an important facilitator of negotiations between parents and teenagers regarding boundary setting. We conclude that the mobile phone has enabled teenagers to gain increased leverage in their negotiations with their parents, but underline that parents still hold control and authority by ‘invading’ their children's space.
Music-Based Procedural Content Generation for Games

A geracao procedimental e algo ainda recente no mundo academico, que se entende como a criacao de conteudos automaticamente via algoritmos. Ha varias razoes para o desenvolvimento desta tecnica, mas a principal e a reducao da memoria consumida, pois os algoritmos de geracao procedimentais sao capazes de gerar conteudo em massa, ocupando ordens de magnitude menores em disco. Este procedimento e, normalmente, utilizado em jogos para gerar niveis, mapas, vegetacao, missoes, sendo menos comum para gerar ou alterar o motor de jogo ou o comportamento de NPCs (Non-Player Character). Apesar de a maioria dos jogos possuirem musica, e frequente este elemento apenas servir como suporte ao jogo e ajudar a criar o ambiente necessario. Os jogos que utilizam a musica como fonte de informacao para criar conteudo jogavel ainda sao raros e mesmo nestes o conteudo gerado e, muitas vezes, gerado previamente e estatico. Nesse sentido, novos jogos tem vindo a diferenciar-se neste processo, nos quais a musica escolhida ira gerar conteudos automaticamente e de forma diversa. O objetivo desta dissertacao e desenvolver um jogo, de forma completamente procedimental a partir de segmentos de musica, com o intuito de ser possivel diferenciar de forma significativa os diferentes niveis criados e ser capaz de tirar conclusoes referentes a utilizacao de musica como gerador procedimental de conteudos. Jogo este que sera composto por missoes de stealth onde e necessario ao jogador atravessar todo o nivel com os recursos que encontrar e sem ser visto/apanhado pelos inimigos. O jogo consistira, entao, em receber uma musica ou segmento de musica como input e atraves de uma analise individual poder recolher algumas caracteristicas importantes que o irao distinguir de outros. Apos este processo, cada nivel sera criado consoante estes, permitindo diversidade em cada missao, principalmente de forma a condicionar o modo como esta sera jogada.
Characterization of diarrheagenic Escherichia coli strains associated with diarrhea in children, Khouzestan, Iran.

INTRODUCTION Diarrheagenic Escherichia coli (DEC) is a major etiologic agent among the pathogens that cause diarrhea in children. METHODOLOGY To investigate the presence and pathotypes of DEC in children under five years of age, living in the province of Khouzestan, Iran. 208 diarrhea stool samples were screened by multiplex-PCR. The isolated DEC isolates were investigated for resistance to various antimicrobials including the production of extended-spectrum beta-lactamases (ESBLs) and phylogenetic groups were determined. RESULTS DEC isolates were identified in 54 (26%) diarrhea samples, and 4 (7%) cases contained two DEC pathotypes. DEC isolated included 35 (16.8%) enteroaggregative E. coli (EAEC), ten (4.8%) enteropathogenic E. coli (EPEC), six (2.9%) enteroinvasive E. coli (EIEC), six (2.9%) enterotoxigenic E. coli (ETEC) and one (0.48%) LEE-positive EAEC. Shiga-toxin producing E. coli (STEC) was not identified in any diarrheal samples. The most prevalent resistance was observed with ceftazidime (88%), followed by ceftizoxime (83%) and ceftriaxone (71%). The majority of isolates (> 75%) were sensitive to Imipenem, ciprofloxacin, and amikacin. More than 65% of the pathogenic isolates showed a multidrug-resistant phenotype. ESBL-producing strains was observed in 79.3% of all DEC isolates. Phylogenetic group B2 was the most predominant group with a frequency of 44.8%. A significant association was observed between the B2 phylogenetic group and the DEC isolates (P < 0.05). CONCLUSIONS Overall, our findings highlight the importance of the role of DEC isolates in the etiology of diarrhea in children in Iran. The progressive increase in antimicrobial resistance among DEC isolates makes it imperative to implement policies to control the spread of resistant bacteria.
Teachers as Designers: Multimodal Immersion and Strategic Reading on the Internet

Multimodal literacy and learning on the Internet are core components of 21st century literacies, as promulgated in the Common Core State Standards Initiative (2011) and position papers of the International Reading Association (2009) and National Council of Teachers of English (2008). Technology is assumed to be part of the solution to “transforming American education” to achieve highquality education for all students (National Education Technology Plan, 2010, p. ix). It is expected that teachers will be able to integrate technology effectively into instruction and prepare their students to be creative producers and critical consumers of digital media, resources, and tools. Much of this learning and interaction is taking place on the Internet, a new literacies learning environment that offers affordances and challenges for reading and learning (Coiro, 2011; Dalton & Proctor, 2008; Leu, Kinzer, Coiro, & Cammack, 2004). Although there is general consensus amongst stakeholders concerning the necessity of teaching digital literacies, there are wide gaps between the standards and teachers’ actual practices (Lankshear & Knobel, 2007), and between adolescents’ experience with technology in and outside of school (Ito et al., 2009). Many teachers lack the skills and knowledge to integrate technology successfully (e.g., Koehler, Mishra, & Yahya, 2007; NEA/AFT, 2008) and report feeling ill-prepared to develop the new literacies endemic to the Internet or to support students who struggle to comprehend and apply its sophisticated, complex information (Grunwald Associates LLC, 2009; Mallette & Karchmer, 2002). Further, teachers’ technology integration often promotes traditional approaches to instruction and literacy (Wallace, 2004). This study examined teachers’ literacy and technology integration in their design of Internet-based lessons for Grade 1-6 students using a tool that scaffolds the design process to focus on Internet resources and reading strategies. Twenty-six teachers’ lessons on a public database were analyzed for design orientation, goals, curricular integration, linked web site characteristics, reading strategies, and student response. Findings suggested that the tool shaped teachers’ designs, supporting embedding of Internet multimodal resources and comprehension strategies in online lessons. Teachers’ dominant design orientation was to provide students with a multimodal immersion experience to enhance understanding and engagement with literature or other subject-matter. The majority of teachers took advantage of reading strategies support, with more than one half customizing pedagogical agents. Few teachers used web evaluation or media literacies support. The potential for educative design tools is discussed.

Elemental ratios in stars vs planets (Research Note)

Context. The chemical composition of planets is an important constraint for planet formation and subsequent differentiation. While theoretical studies try to derive the compositions of planets from planet formation models in order to link the composition and formation process of planets, other studies assume that the elemental ratios in the formed planet and in the host star are the same. Aims. Using a chemical model combined with a planet formation model, we aim to link the composition of stars with solar mass and luminosity with the composition of the hosted planets. For this purpose, we study the three most important elemental ratios that control the internal structure of a planet: Fe/Si, Mg/Si, and C/O. Methods. A set of 18 different observed stellar compositions was used to cover a wide range of these elemental ratios. The Gibbs energy minimization assumption was used to derive the composition of planets, taking stellar abundances as proxies for nebular abundances, and to generate planets in a self-consistent planet formation model. We computed the elemental ratios Fe/Si, Mg/Si and C/O in three types of planets (rocky, icy, and giant planets) formed in different protoplanetary discs, and compared them to stellar abundances. Results. We show that the elemental ratios Mg/Si and Fe/Si in planets are essentially identical to those in the star. Some deviations are shown for planets that formed in specific regions of the disc, but the relationship remains valid within the ranges encompassed in our study. The C/O ratio shows only a very weak dependence on the stellar value.
In - vitro biological activities of Emericella nidulans, a new fungal antagonist, against Fusarium oxysporum f. sp. lycopersici

Biculture test for antagonism showed that E. nidulans exerted inhibitory activity against F. oxysporum f. sp. lycopersici. In slide biculture, the conidia and hyphae of the pathogen were deformed, abnormal in shape and showed protoplast plugs inside. The crude extract of E. nidulans applied at the rate of 1000 ug/ml gave significantly higher inhibition of mycelial growth and spore formation while 10 ug/ml gave the largest mycelial diameter and lowest growth inhibition (p<0.01). Hexane and ethyl acetate extract registered significantly higher mycelial diameter and spore formation and lower mycelial growth and spore production inhibition while methanol extract produced significantly lower mycelial growth and spore production but higher mycelial growth and spore inhibition (p<0.01).
Statistical Analysis of Relationship between Daytime Lidar-Derived Planetary Boundary Layer Height and Relevant Atmospheric Variables in the Semiarid Region in Northwest China

Accurate identification of key parameters for data assimilation is important in simulating the planetary boundary layer height (PBLH) and structure evolution in numerical weather prediction models. In this study, surface observational data and lidar-derived PBLH on 42 cloudless days from June 2007 to May 2008 are used to quantify the statistical relationships between surface parameters and the PBLH at a semiarid climate observational site in Northwest China. The results indicate that surface upward long wave radiation, surface temperature, and surface sensible heat fluxes show strong correlations with the PBLH with correlation coefficients at a range of 0.63–0.72. But these parameters show varying correlation response time to the different stages of PBL development. Furthermore, the air temperature shows the highest correlation with the PBLH near the surface and the correlation decreases with increasing height.
Feeding Polyunsaturated Supplements to Grazing Dairy Cows Improve the Healthy Value of Milk Fatty Acids

The objective of the experiment was to improve the healthy value of milk fatty acids (FA) by feeding sunflower oil (SO) or sunflower seed (SS) combined or not with fish oil (FO) to grazing dairy cows. Four Holstein cows (515 ± 80 kg liveweight) in late lactation (230 days postpartum) fitted with ruminal cannulae were allotted to a 4 × 4 Latin square design with factorial arrangement of treatments: SS = 1.9 kg dry matter (DM)/cow/d of SS; SO = 0.8 kg/cow/d of SO; SS-FO = SS + 0.24 kg/cow/d FO and SO-FO = SO + 0.24 kg/FO. Cows grazed a high quality pasture offered at 11 kg DM/cow/day. After the afternoon milking cows also received 5.6 kg DM/cow of corn silage and during each milking time cracked corn grain (1.3 kg DM/cow) mixed with a mineral-vitamin premix was fed. Oils and SS were introduced via ruminal cannulae and SS was fed roughly grounded. Milk yield tended (p < 0.07) to increase in SO treatments (9.9 vs 8.7 kg/d). Yields (kg/d) of fat corrected milk (FCM) (8.01 vs 6.37) and milk fat (0.27 vs 0.191) increased (p < 0.05) in SO diets and milk fat content was not affected. Milk protein concentration (40.5 vs 37.0 g/kg) and yield (0.397 vs 0.322 kg/d) were higher (p < 0.05) in SO without effects of FO or their interaction. Milk cholesterol content did not differ. The reduction in the atherogenic saturated FA of milk averaged 63% for C12:0, 51% for C14:0 and 29% for C16:0. Atherogenicity index (AI) of milk was reduced particularly in SS-FO. Basal concentration of cis-9, trans-11 C18:2 (CLA) in milk was 1.39 g/100g FA and increased (p < 0.05) by 144% across treatments without differences between SS or SO. Feeding FO increased (p < 0.05) milk contents of CLA (2.86 to 3.92 g/100g FA) and linolenic acid. Comparing SO or SS with or without FO showed no changes for neutral detergent fiber (NDF) and crude protein (CP) degradation of pasture. Polyunsaturated fatty acid (PUFA) fed to grazing dairy cows had a marked effect on milk FA profile putatively enhancing its healthy value.
