    Effective space ordering, characterize by small varies spaces, is very crucial on apartement design. Apartement design which has huge numbers of floors will eventually reconsider how to choose structures types to achieve the most effective solution on space ordering. Therefore, shearwall structure is one of the alternatives on apartement design. Shearwall sructure study main pupose is to analyze the effective values of apartement small space which has been presented in the architecture seminar subject. Writer choose Nirvana apartement of Kemang, Jakarta, due to its shearwall structure system. The study mainly done by analyzing effective values (standard furniture, adaftive, space layout) as parameters to acknowledge the effective values of small spaces. Nirvana apartement has a long croos sectional area which makes the building slim with 14 levels of floors. Shearwall structure has been planted as the base structure due its supporting values and safety reason local earthquake

    Kerupuk is one of complementary food almost in all Indonesia\u27s food. Kerupuk has function to increase taste because its delicious and consist of many variation. On of kerupuk producen is Mrs.Muayanah. Mrs.Muayanah has produced kerupuk for ten years. However, her business is stagnant because limited stuffs and her stuffs still simple so can\u27t produce in big number especially drying process which take longest time of all production process. From that description, we try to give solution designing solar oven to increase kerupuk productivity. APKOSTRIK is dryer which use solar and reflect it to the object (kerupuk) to help drying process by using solar collector. By reflecting and focusing solar sun, it will increase received hot energy till maximal and less time needed. Another that, solar also absosrbed by copper plate and temperature will keep increasing because copper plate absorb hot energy from direct solar and reflected one to increase drying speed. Room also affect drying process because room is isolated by alumunium. This simple functional oven can help increasing kerupuk productivity and profit because without any complicated knowledge or experiences everyone can use it. This oven also need not any electricity and production cost so low economic citizen or micro business can be prosperous especially in kerupuk business

    There are few studies in Spain which analyze the influence of individual, motivational and contextual variables, which might be different between underachieving, normally achieving and overachieving students. Method: A total of 1,398 Spanish high school students participated. Mixed-effects models were used to analyze data. Results: The results showed some evidence of: (a) Partial mediational effect of self-concept on the association between cognitive ability and academic achievement. (b) Higher levels of learning goals in the overachieving group than in the underachieving group, but no differences in achievement and reinforcement goals between groups. (c) Positive effect of learning strategies on attainment, both in the underachieving and the non-underachieving students. (d) Little effect of context variables on academic achievement, both in the underachieving and non-underachieving students. Conclusions: Underachieving students seem to employ all the learning strategies considered to a lesser extent than normally and overachieving students. They also have a lower level of learning goals. On the contrary, overachieving students score more highly than under and normally achieving students in almost all of the above factors.Antecedentes: apenas existen estudios en España que analicen la influencia de variables cognitivas, motivacionales y contextuales capaces de establecer diferencias entre los estudiantes con rendimiento menor, igual y mayor al esperado. Método: participaron 1.398 estudiantes españoles de Educación Secundaria Obligatoria. Se emplearon modelos de efectos mixtos para el análisis de datos. Resultados: los resultados mostraron evidencia de: (a) efecto mediacional parcial del auto-concepto en la asociación de la habilidad cognitiva y el rendimiento académico; (b) mayores niveles de metas de aprendizaje en el grupo de estudiantes con rendimiento mayor al esperado; (c) efecto positivo de las estrategias de aprendizaje sobre el rendimiento en todos los grupos; (d) efecto pequeño de las variables contextuales sobre el rendimiento en todos los grupos. Conclusiones: los estudiantes con rendimiento menor al esperado emplean en menor medida las estrategias de aprendizaje y las metas orientadas al aprendizaje. Por el contrario, los estudiantes con rendimiento mayor al esperado muestran niveles superiores que el resto de grupos en la mayor parte de variables.The present work was supported by the Spanish Ministry of Economy and Competitiveness (Award number: EDU2012-32156) and the Vice Chancellor for Research of the University of Alicante (Award number: GRE11-15).

    Hydrophilic interaction liquid chromatography (HILIC) in proteomics

    Get PDF
    In proteomics, nanoflow multidimensional chromatography is now the gold standard for the separation of complex mixtures of peptides as generated by in-solution digestion of whole-cell lysates. Ideally, the different stationary phases used in multidimensional chromatography should provide orthogonal separation characteristics. For this reason, the combination of strong cation exchange chromatography (SCX) and reversed-phase (RP) chromatography is the most widely used combination for the separation of peptides. Here, we review the potential of hydrophilic interaction liquid chromatography (HILIC) as a separation tool in the multidimensional separation of peptides in proteomics applications. Recent work has revealed that HILIC may provide an excellent alternative to SCX, possessing several advantages in the area of separation power and targeted analysis of protein post-translational modifications

    Hydrophilic interaction liquid chromatography (HILIC)—a powerful separation technique

    Get PDF
    Hydrophilic interaction liquid chromatography (HILIC) provides an alternative approach to effectively separate small polar compounds on polar stationary phases. The purpose of this work was to review the options for the characterization of HILIC stationary phases and their applications for separations of polar compounds in complex matrices. The characteristics of the hydrophilic stationary phase may affect and in some cases limit the choices of mobile phase composition, ion strength or buffer pH value available, since mechanisms other than hydrophilic partitioning could potentially occur. Enhancing our understanding of retention behavior in HILIC increases the scope of possible applications of liquid chromatography. One interesting option may also be to use HILIC in orthogonal and/or two-dimensional separations. Bioapplications of HILIC systems are also presented

    Emotional intelligence training intervention among trainee teachers: a quasi-experimental study

    Get PDF
    Background: Emotional intelligence (EI) has often been linked to improvements in professional performance. Indeed, generic competencies related to EI have been included in university curricula. However, learning EI involves significant time and effort on the part of students, and this may hinder the acquisition of specific content for each degree. In this study, an intervention to develop EI in higher education students is described and evaluated. Methods: The intervention consisted of eight group sessions performed in a regular course aiming to increase EI. The sessions included strategies and training on perceiving and understanding one’s own emotions and others’ emotions, identifying and understanding the impact one’s own feelings in adopting decisions, expressing one’s own emotions and the stress experienced, and managing both one’s own emotions and emotions of others. Participants were 192 students studying for a Master of Primary Education degree. A quasi-experimental nonequivalent control group pretest-posttest design was adopted. The effectiveness of the intervention was evaluated using multi-level analyses. Results: The results showed a significant improvement in the EI of students in the experimental group compared with the control group. Conclusions: This research demonstrates that it is possible to develop EI in higher education students, without hindering the acquisition of specific content competencies and, therefore, without interfering with their academic performance and without overburdening students with work outside the classroom. Trial registration: The experiment has been registered in the Initial Deposit of the Spanish Center for Sociological Research (CIS). 7/6/2015. http://www.cis.es/cis/opencms/ES/index.html.This research was supported by the Spanish Ministry of Economy and Competitiveness under Grant number EDU2015-64562-R

    Selective Removal of Alkali Metal Cations from Multiply-Charged Ions via Gas-Phase Ion/Ion Reactions Using Weakly Coordinating Anions

    Full text link
    Selective removal of alkali metal cations from mixed cation multiply-charged peptide ions is demonstrated here using gas-phase ion/ion reactions with a series of weakly coordinating anions (WCAs), including hexafluorophosphate (PF6 (-)), tetrakis[3,5-bis(trifluoromethyl)phenyl]borate (BARF), tetrakis(pentafluorophenyl)borate (TPPB), and carborane (CHB11Cl11 (-)). In all cases, a long-lived complex is generated by dication/anion condensation followed by ion activation to compare proton transfer with alkali ion transfer from the peptide to the anion. The carborane anion was the only anion studied to undergo dissociation exclusively through loss of the metallated anion, regardless of the studied metal adduct. All other anions studied yield varying abundances of protonated and metallated peptide depending on the peptide sequence and the metal identity. Density functional theory calculations suggest that for the WCAs studied, metal ion transfer is most strongly favored thermodynamically, which is consistent with the experimental results. The carborane anion is demonstrated to be a robust reagent for the selective removal of alkali metal cations from peptide cations with mixtures of excess protons and metal cations
