Latina Educators and School Discourse: Dealing With Tension on the Path to Success

The disparity in racial and ethnic identity between students and teachers highlights the need for successful Latina/os to enter the teaching profession. This study aimed toward understanding the effects of schooling for successful Latina/os. Five beginning bilingual and biliterate Latina teachers were interviewed multiple times regarding their schooling experiences. Our analyses of these data led us to conclude that significant conflicts between home and school discourses were experienced throughout schooling. Participants described strategies of ongoing, sometimes difficult, negotiation between discourses. We contend that dialogue among teachers regarding conflicting discourses can develop critical awareness and systems of mutual support.
Anatomy of Mahakala omnogovae (Theropoda: Dromaeosauridae), Tögrögiin Shiree, Mongolia

ABSTRACT The dromaeosaurid Mahakala omnogovae is known from a unique specimen from the Late Cretaceous deposits of the Djadokhta Formation at Tögrögiin Shiree, Ömnögov Aimag, Mongolia. The holotype specimen is comprised of a well-preserved but partial skull and a nearly complete postcranial skeleton. Mahakala omnogovae is included in a comprehensive phylogenetic analysis of Coelurosauria using a dataset, which reflects a greatly expanded character set and taxon-sampling regime. Several interesting features of Mahakala omnogovae have implications for deinonychosaurian and avialan character evolution and for understanding patterns of size variation and size change within paravian theropods. These morphologies include the shape of the iliac blade, the triangular obturator process of the ischium, and the evolution of the subarctometatarsalian condition. We present an expanded diagnosis of Mahakala omnogovae, which included following unique combination of characters (autapomorphies noted by *): a ledgelike depression at the confluence of metotic strut and posterior tympanic recess on the anterior face of the paroccipital process*, a posteriorly tapering scapula; a shortened forelimb (humerus 50% femur length); a strongly compressed and anteroposteriorly broad ulna tapering posteriorly to a narrow edge*; elongate lateral crest on the posterodistal femur*; anterior caudal vertebrae with subhorizontal, laterally directed prezygapophyses*; a prominent supratrochanteric process; and the absence of a cuppedicus fossa.
Effect of hardening method and structure of linking bridges on strength of water glass moulding sands

The paper presents examination results of the effect of four hardening methods on structure of linking bridges in sandmixes containing hydrated sodium silicate. Test pieces prepared of the moulding sands containing 2.5 % of a binder with molar module between 2.4 and 2.6 were hardened with carbon dioxide, dried traditionally in an oven and hardened with microwaves at 2.54 GHz or using a combination of the CO2 process and microwave heating. It was revealed that the hardening method influences structure of linking bridges and is correlated with mechanical properties of the hardened moulding sands. It was found that strength of the moulding sands microwave-heated for 240 s is approximate to that measured after traditional drying for 120 min at 110 °C. So, the microwave hardening permits significant reduction of the process time, comparable to the CO2 hardening, at the same time guaranteeing over 10 times higher mechanical properties. Analysis of SEM photographs of the moulding sands hardened with the mentioned methods allow explaining differences in qualitative parameters of the moulding sands and their relation to structures of the created linking bridges.
FOOTPRINT MAP PARTITIONING USING AIRBORNE LASER SCANNING DATA

Abstract. Nowadays many cities and countries are creating their 3D building models for a better daily management and smarter decision making. The newly created 3D models are required to be consistent with existing 2D footprint maps. Thereby the 2D maps are usually combined with height data for the task of 3D reconstruction. Many buildings are often composed by parts that are discontinuous over height. Building parts can be reconstructed independently and combined into a complete building. Therefore, most of the state-of-the-art work on 3D building reconstruction first decomposes a footprint map into parts. However, those works usually change the footprint maps for easier partitioning and cannot detect building parts that are fully inside the footprint polygon. In order to solve those problems, we introduce two methodologies, one more dependent on height data, and the other one more dependent on footprints. We also experimentally evaluate the two methodologies and compare their advantages and disadvantages. The experiments use Airborne Laser Scanning (ALS) data and two vector maps, one with 1:10,000 scale and another one with 1:500 scale.
A Projection Neural Network for Circular Cone Programming

A projection neural network method for circular cone programming is proposed. In the KKT condition for the circular cone programming, the complementary slack equation is transformed into an equivalent projection equation. The energy function is constructed by the distance function and the dynamic differential equation is given by the descent direction of the energy function. Since the projection on the circular cone is simple and costs less computation time, the proposed neural network requires less state variables and leads to low complexity. We prove that the proposed neural network is stable in the sense of Lyapunov and globally convergent. The simulation experiments show our method is efficient and effective.
New Halo White Dwarf Candidates in the Sloan Digital Sky Survey

We present optical spectroscopy and near-infrared photometry of 57 faint ($g= 19-22$) high proper motion white dwarfs identified through repeat imaging of $\approx3100$ square degrees of the Sloan Digital Sky Survey footprint by Munn et al. (2014). We use $ugriz$ and $JH$ photometry to perform a model atmosphere analysis, and identify ten ultracool white dwarfs with $T_{\rm eff} 120$ km $s^{-1}$) and UVW velocities that are more consistent with the halo than the Galactic disc. For typical $0.6 M_{\odot}$ white dwarfs, the cooling ages for these halo candidates range from 2.3 to 8.5 Gyr. However, the total main-sequence + white dwarf cooling ages of these stars would be consistent with the Galactic halo if they are slightly undermassive. Given the magnitude limits of the current large scale surveys, many of the coolest and oldest white dwarfs remain undiscovered in the solar neighborhood, but upcoming surveys such as GAIA and the Large Synoptic Survey Telescope (LSST) should find many of these elusive thick disc and halo white dwarfs.
Overview of the EU FP 7-project HISTORIC

HISTORIC aims to develop and test complex photonic integrated circuits containing a relatively large number of digital photonic elements for use in e.g. all-optical packet switching. These photonic digital units are all-optical flip-flops based on ultra compact laser diodes, such as microdisk lasers and photonic crystal lasers. These lasers are fabricated making use of the heterogeneous integration of InP membranes on top of silicon on insulator (SOI) passive optical circuits. The very small dimensions of the lasers are, at least for some approaches, possible because of the high index contrast of the InP membranes and by making use of the extreme accuracy of CMOS processing. All-optical flip-flops based on heterogeneously integrated microdisk lasers with diameter of 7. 5μm have already been demonstrated. They operate with a CW power consumption of a few mW and can switch in 60ps with switching energies as low as 1.8 fJ. Their operation as all-optical gate has also been demonstrated. Work is also on-going to fabricate heterogeneously integrated photonic crystal lasers and all-optical flip-flops based on such lasers. A lot of attention is given to the electrical pumping of the membrane InP-based photonic crystal lasers and to the coupling to SOI wire waveguides. Optically pumped photonic crystal lasers coupled to SOI wires have been demonstrated already. The all-optical flip-flops and gates will be combined into more complex photonic integrated circuits, implementing all-optical shift registers, D flip-flops, and other all-optical switching building blocks. The possibility to integrate a large number of photonic digital units together, but also to integrate them with compact passive optical routers such as AWGs, opens new perspectives for the design of integrated optical processors or optical buffers. The project therefore also focuses on designing new architectures for such optical processing or buffer chips.
Evaluation of Antidiabetic Activity From the Root Extracts of Pavonia Odorata Wild in Alloxan Induced Diabetic Rates

Pavonia odorata wild belongs to the family Malvaceae. It is a herb. Its roots have musk like aromatic odour. The roots yield an essential oil that contains isovaleric acid, isovaleraldehyde, aromadendrene, pavonene, a-terpinene, azulene and pavonenol. The roots are aromatic, and possess refrigerant, antipyretic, stomachic and astringent properties. Based on ethno pharmacological information , Pavonia Odorata Wild has been used to treat diabetes by the tribals in and around tropical and subtropical areas. But there are no more scientific reports available about the antidiabetic activity of this plant. Hence the study was carried out to ascertain the activity. The toxic effect of MeOH extract of Pavonia odorata root was studied at a dose level up to 2000 mg/kg b.w. The plant extracts were also evaluated for antidiabetic activity at a dose levels of 100 mg/kg of CHCl3 , 100 mg/kg of EtOAc and 200 mg/kg of MeOH in Alloxan induced diabetic rats. The plant extracts have not produced any toxic symptoms within the treated animals. In the high light of the results, our study indicates that Pavonia odorata root extracts have antidiabetic activity.The lowest blood glucose(157.00±4.36) levels was observed at 15 th day after oral administration of 100 mg/kg of CHCl3 extract of Pavonia odorata root . From the observations, it was concluded that the reduction of blood glucose levels in diabetic rats were found to be dose dependent and also dependent on duration of action. So it might be useful in the treatment of diabetes without toxicity.
Modificación estructural de ácido trans-cinámico empleando Colletotrichum acutatum

Se estudio la biotransformacion de acido trans-cinamico mediante celulas completas del hongo fitopatogeno nativo colombiano Colletotrichum acutatum. Inicialmente, se evaluo la fungitoxicidad de este compuesto contra C. acutatum; el acido trans- inamico exhibio una toxicidad moderada a debil contra el microorganismo y aparentemente se presento un mecanismo de detoxificacion. Luego, para estudiar tal mecanismo y explorar la capacidad de este hongo para biotransformar el acido trans- inamico en productos con valor agregado, el microorganismo se incubo con el sustrato usando tres medios de cultivo diferentes (Czapeck-Dox, Sabouraud y PDB) a condiciones ambientales. Usando el medio Czapeck-Dox, los cultivos completos de C. acutatum redujeron el acido trans-cinamico, primero a aldehidos (transcinamaldehido y 3-fenilpropanal), luego a alcoholes (alcohol cinamilico y 3-fenil-1-propanol). Posteriormente, estos alcoholes fueron transformados a los correspondientes esteres de acetilo. Sin embargo, algunos de estos productos estuvieron ausentes o presentes a una concentracion diferente cuando se cambio el medio de cultivo. Los resultados sugieren un mecanismo de detoxificacion en el cual el sistema carbonilico α,β-insaturado es afectado. Por otra parte, los productos metabolicos formados son compuestos utiles usados como fragancias y sabores. Por consiguiente, el metabolismo del acido trans-cinamico usando C. acutatum puede proporcionar nuevos blancos metabolicos para controlar C. acutatum asi como tambien una forma simple y eficiente para obtener sabores y perfumes, tales como el alcohol cinamilico y el 3-fenil-1-propanol, y sus esteres de acetilo.
Analysis of PassivelyQ-Switched Lasers With Simultaneous Modelocking

Simultaneous Q-switching and modelocking in a diode-pumped Nd : YAG/Cr : YAG laser is experimentally demonstrated. A general recurrence is derived for the analysis of the temporal shape of a singleQ-switched envelope with modelocked pulse trains. With the developed model, the modelocked pulse energy and the totalQ-switched pulse energy can be calculated. Excellent agreement was found between the present results and detailed theoretical computations.
Middle School Students’ Free-living Physical Activity on Physical Education Days, Non-physical Education Days, and Weekends

This study measured students’ free-living Physical Activity (PA) in order to examine activity patterns of youth. Students (N=221) in 12-classes wore accelerometers to measure their PA over six weeks in and out-of-school while participating in a fitness unit. PA was significantly higher during Non-PE-Days and PE-Days than on Sundays. PA was significantly higher during baseline than weeks five and six. There were no significant differences between boys and girls in the number steps taken. Eighth-grade students had the lowest PA levels. On average, the students were attaining 60 minutes of MVPA. Students, however, did not often reach national recommendations. Girls reached their national recommendations five out of six weeks on days that they participated in PE. The results suggest that specific subgroups, such as adolescent girls, are getting the recommended PA but only when the PA is structured. A spike in PA during the first week suggested a possible motivational effect of the accelerometer.
LIE-TRANSFORM DERIVATION OF THE GYROKINETIC HAMILTONIAN SYSTEM

LIE-TRANSFORM DERIVATION OF THE GYROKINETIC HAMILTONIAN SYSTEM LBL-16962 Allan N. Kaufman* and Bruce M. Boghosian** The Hamiltonian structures of the self-consistent gyrokinetic equations, and of the cold guiding-center plasma, are derived from first principles. The Vlasov system is first formulated as an action principle, and is then subjected to a single-particle Lie transform. The resulting expression then yields the Poisson structure, on functionals of the guiding-center distribution, and the system Hamiltonian. The self-consistent field is eliminated by a subsidiary conditi.on. The Lie transform [1,3,4,11] has proved to be a very successful tool for systematically reducing the Hamiltonian description of single-particle motion. In the area of plasma physiCS, the. chief applications have been to the concepts of oscillation-center motion [2,6,7] and guiding-center motion [10,12]. This method transforms to higher order the ·effects of oscillatorj motion and gyration, respectively. These higher order terms then contribute, for example, to ponderomotive effects [2,6] and to wave coupling [7]. In order to obtain a (self-consistent) system Hamiltonian corresponding to this reduced description, it is necessarY to imbed the single-particle Lie transform in a many-particle or continuum framework which includes the self-consistent fields. In the companion paper (9], a Lagrangian prinCiple is presented for the Vlasov equation with Coulomb interaction, which leads to the accepted Hamiltonian structure of the Vlasov equation. However, that principle utilizes particle orbits in configuration space, and thus is of no help for the Lie transform, which operates in particle phase space. In this paper, the action principle for the Vlasov system is first fontiulated in particle phase space. The invariance of the particle action integral under canonical transformations then enables us to effect the Lie 1980 Mathematics Subject Classification 76XOS, 70H05, SaFOS.

Participation of Women in Rural Cooperatives: Evidence from Gewane and Fentale Districts of Afar Region, Ethiopia

The study was conducted in Fentale and Gewane districts of Afar, in north eastern Ethiopia with the objectives: to assess the extent of women’s’ participation in rural cooperatives and to examine major factors influencing women’s participation in rural cooperatives. Data for the study were derived from 10 purposively selected cooperatives. All women members were considered. The primary data necessary for the quantitative study were collected through personal interviews from 90 women drawn purposefully from 10 cooperatives by conducting formal survey using structured interview schedule. Qualitative data were collected through focus group discussion, observations, and informal discussion with key informants. Descriptive statistics with appropriate statistical tests, T test for significant and Karl Pearson’s Correlation were used to analyse the data. The findings showed that women are conspicuously under-represented in decision making, implementing decisions, shouldering responsibility, attending general meeting, involvement in share purchasing and leadership. The survey result showed that the majority of the respondents were not aware of the rules, the by-laws, principles, values, rights and obligation of members and how income is distributed. The output of Pearson correlation analysis indicated that age, duration of membership, livestock ownership, total income, distance, awareness about cooperative, training access, position of women, shows a significant relationship with participation. Lack of awareness, culture, lack of access to information, work load in the house, lack of education, lack of capital, the negative attitude of the society towards women and mobility were the most important factors contributing to the inactive participation of women in cooperatives in the study area. Therefore, cooperatives should focus on creating awareness, educating women, increasing training access to women and educating the society to bring attitudinal change on gender issue. Keywords : women, participation, cooperative.
Estimating the willingness to pay for improved municipal solid waste management in Nairobi, Kenya

The rapid accumulation of municipal solid waste in many developing countries has been linked to urbanization, population growth and low budgetary allocation for urban solid waste management. This study aims at determining the households’ willingness to pay for improved solid waste management to reduce air pollution in Nairobi, Kenya. In order to undertake the study, the sample of 114 households around the Dandora dumpsite in Nairobi was randomly selected from Dandora, Babadogo, Kariobangi North and Korogocho residential areas that were purposively selected. The technique employed in the assessment is a stated preference approach called contingent valuation method. Double-bounded model was used to identify the factors that influence the households’ willingness to pay for improved solid waste management. The results from this study show that the willingness to pay for households is significantly related to monthly income, gender of the household head, household size and education level of the household head. In addition, the results also reveal that gender of household head is negatively correlated with willingness to pay while monthly income, size of the household and education level of the household head are positively correlated with willingness to pay for improved solid waste management. The results of contingent valuation further reveal that the mean willingness to pay for improved solid waste management per household in order to reduce air pollution is Kshs. 237.14 per month. Therefore, there is need for policy makers to involve the urban households in managing municipal solid waste for sustainable environmental protection in the developing countries

Refer to this research, a position parallel error-based fuzzy inverse dynamic plus gravity controller is proposed for continuum robot manipulator. The main problem of the pure inverse dynamic controller was equivalent dynamic formulation in certain and uncertain systems. The nonlinear equivalent dynamic problem in uncertain system is solved by using fuzzy logic theory. To estimate the continuum robot manipulator system's dynamic, 49 rules Mamdani inference system is design and applied to inverse dynamic plus gravity methodology. This methodology is based on applied fuzzy logic in equivalent nonlinear dynamic part to estimate unknown parameters. The results demonstrate that the error-based parallel fuzzy inverse dynamic plus gravity controller is a partly model-free controllers which works well in certain and partly uncertain system.
Screening of Marine Bacteria Capable of Degrading Various Polyaromatic Hydrocarbons

This research aims to screen and to identify marine bacteria able to degrade Polyaromatic Hydrocarbons (PAHs). 7 bacterial isolates were screened for the ability to degrade 6 PAHs (phenanthrene, naphthalene, dibenzothiophene, fluorene, phenothiazine, and pyrene). This screening step was conducted by sublimation method, in which the color change or clear zone appearance was used as an qualitative indicator to show the capability of the selected isolate to degrade PAHs. Two bacterial isolates, designated as LBF-1-0102 and LBF1-0103, showed capability in degradating the PAHs tested. In particular, the isolate LBF-1-102 was potential in degrading phenanthrene, naphthalene, dibenzothiphene, fluorene, phenothiazine, and pyrene.The isolate LBF-1-0103 showed the ability in degrading 2 (two) PAHs, i.e. dibenzothiophene and fluorene. Based on partial 16S rDNA analysis, LBF-1-0102 and LBF-1-0103 were identified as Pseudomonas balerica and Brachybacterium sp. , respectively.
Effect of a concurrent training session with different intensities in post-exercise blood pressure responses in normotensive adults

Effect of a concurrent training session with different intensities in post-exercise blood pressure responses in normotensive adults. The purpose of this study was to analyze the effect of a concurrent training session (CT) with different intensities in post-exercise blood pressure responses in normotensive adults. Ten normotensive adult males participated in this study, they performed four experimental protocols: a) Strength Training (ST) at 50% of 1RM and aerobic training (AT) between 50-60% of the Working Heart Rate (WHR), b) ST at 50% of 1RM and AT between 80-90% of the WHR, c) ST at 85% of 1RM and AT between 50-60% of the WHR, d) ST at 85% of 1RM and AT between 80-90% of the WHR. Every protocol presented a decrease in the systolic blood pressure 1 minute after finishing the training session, however, only the protocol with the intensity of 50% 1RM and 80-90% WHR presented a significant hypotensive effect (p ≤ 0,05). None of the protocols presented a significant decrease in the diastolic blood pressure. We came to the conclusion that the hypotensive effect in the SBP can be observed when the CT is performed at the intensity of 50% of 1RM and of 80-90% of the WHR.
