Chemical Stabilization of Amorphous Peat Using Cement and Fly Ash at Different Water Additive Ratios

Field: Engineering (Physical Sciences)

Peat is a very problematic soil as it is poor in strength. However, previous researchers have proven that the compressive strength of peat can be improved by using various methods of soil improvement including chemical stabilization method. In this study, cement and fly ash and lime were additives used and were mixed with amorphous peat at various water additive ratios. To replicate actual stabilization on site, water additive ratio is proposed as to allow stabilization to be performed at natural water content of the peat. Peat samples were collected from Kampung Endap, Samarahan and mixed at its natural moisture content with cement and with fly ash and lime at different water additive ratios of 3.0, 3.5, 4.0, 4.5 and 5.0. The compressive and bearing strengths of the samples were obtained by the unconfined compressive strength (UCS) test and California Bearing Ratio (CBR) test respectively. The results of the study have shown that there is marginal strength gained after 28 and 56 days of air curing period. The peat samples stabilized with cement at 3.5 water additive ratio recorded the highest value with UCS value of 69.48 kPa after 56 days of curing and 0.52 % for CBR test after 28 days curing period. These strength values obtained are lower compared to published data from previous studies. Different technique of mixing in the laboratory that is mixing peat at its natural water content with varied amount of additives at selected water additive ratio as opposed to mixing at maximum dry density and optimum moisture content that is mostly performed in laboratory contributes to the outcome. However, this study has proven that there is an increase in compressive and bearing strengths of stabilized peat in its natural water content compared to original peat without stabilizer.

Field: Social Sciences (Social Sciences)

This study aims to analyze the implementation of SKUA program management in shaping the religious character of students at MA Ummul Quro Putri Pamekasan. The method used is a qualitative approach with descriptive analysis type. Data collection techniques were obtained through observation, interviews and documentation. Then the data collected was analyzed with the stages of data condensation activities, data presentation, and drawing conclusions or verification. The results of the research that have been conducted show that: First, the process of implementing the SKUA program management in shaping the religious character of students at MA Ummul Quro Putri consists of five stages, planning, organizing, implementing, monitoring and evaluating. Second, the impact obtained is to deepen students scientific treasures, slowly students begin to learn daily practices with discipline, each student begins ti be directed ti have a religious character and students begin to get used ti religius attitudes and traits. Third, the inhibiting factor is the lack of awareness of students how important the SKUA program is in daily life, student personal differences and different environmental factors have a negative impact on the formation of students religious character. Solution that can be done to overcome these inhibiting factors are by firt identifying the problems faced by students and then looking for solutions, providing sanctions related to religion, and providing special guidance to overcome problems that cannot be solved by sanctions.
Ionization energies of multicharged fullerenes: Application and validity of an electrostatic model

Field: Chemistry (Physical Sciences)

A simple relation between the successive ionization energies of polycyclic aromatic hydrocarbons obtained in 1961 by Smith from a calculation of the work required to remove electrons in small particles, is extended here to the fullerene species C n z+ , n = 5070, z = 15, and in some cases up to z = 8. Tests of the validity of the effective values of the parameters of the model, the work function and molecular capacitance, are given. The predicted ionization appearance energies are in excellent agreement with experimental values. A comparison is made between our model and other theoretical approaches to the calculation of the ionization energies of fullerenes. PACS Nos.: 31.20W, 33.80E, 35.20V

Linear mixed model vs two-stage methods: Developing prognostic models of diabetic kidney disease progression

Field: Medicine (Health Sciences)

Identifying prognostic factors for disease progression is a cornerstone of medical research. Repeated assessments of a marker outcome are often used to evaluate disease progression, and the primary research question is to identify factors associated with the longitudinal trajectory of this marker. Our work is motivated by diabetic kidney disease (DKD), where serial measures of estimated glomerular filtration rate (eGFR) are the longitudinal measure of kidney function, and there is notable interest in identifying factors, such as metabolites, that are prognostic for DKD progression. Linear mixed models (LMM) with serial marker outcomes (e.g., eGFR) are a standard approach for prognostic model development, namely by evaluating the time and prognostic factor (e.g., metabolite) interaction. However, two-stage methods that first estimate individual-specific eGFR slopes, and then use these as outcomes in a regression framework with metabolites as predictors are easy to interpret and implement for applied researchers. Herein, we compared the LMM and two-stage methods, in terms of bias and mean squared error via analytic methods and simulations, allowing for irregularly spaced measures and missingness. Our findings provide novel insights into when two-stage methods are suitable longitudinal prognostic modeling alternatives to the LMM. Notably, our findings generalize to other disease studies.
Nonlinear P-Δ analysis of steel frames with semi-rigid connections

Field: Engineering (Physical Sciences)

This paper presents the formulation for a novel force-based 1-D compound-element that captures both material and second order P-${\Delta}$ nonlinearities in steel frames. At the nodal points, the element is attached to nonlinear rotational and a translational springs which represent the flexural and axial stiffness of the connections respectively. By decomposing the total strain in the material as well as the generalised displacements of the flexible connections to their elastic and inelastic components, a secant solution strategy based on a direct iterative scheme is introduced and the corresponding solution strategy is outlined. The strain and slope of the deformed element are assumed to be small; however the equilibrium equations are satisfied for the deformed element taking account of P-${\Delta}$ effects. The formulation accuracy and efficiency is verified by some numerical examples on the nonlinear static, cyclic and dynamic analysis of steel frames.

The Relationship Between Pilot Experience and Aviation Safety Attitudes

Field: Psychology (Social Sciences)

Although the influence of safety attitudes on pilot performance has been documented and research has been conducted on how training can increase safety attitudes, little research has been conducted to understand the relationship between experience and a pilot's safety attitudes. The purpose of this study was to determine whether there is a relationship between pilot experience and pilot attitudes toward safety issues. Pilot attitudes towards safety issues were measured using Hunter's Aviation Safety Attitudes Scale (ASAS). A survey was distributed that included both ASAS and demographic questions. The relationship between flight hours (pilot experience) and the ASAS score was examined.

Synthesis of Size-Controllable Self-Assembled CsPbBr3 Perovskite Nanowires: Implications for Photoemission with Less Recombination

Field: Materials Science (Physical Sciences)

CsPbBr3 perovskite nanowires (NWs) with various lengths and widths have attracted much attention because of their attractive optoelectronic properties in optoelectronic devices. This study provides an effective approach to get size-controllable CsPbBr3 perovskite NWs based on the hot injection method. Oleylamine was used as the solvent to control the reaction speed, and CsPbBr3 perovskite NWs with adjustable widths and lengths were obtained by controlling the reaction time at 180 °C. X-ray diffraction, transmission electron microscopy (TEM), high-resolution transmission electronic microscopy, optical absorption, and photoluminescence (PL) spectra were carried out to investigate the structural evolution and growth mechanism. The results show that Cs4PbBr6 nanocrystals precipitated within 10 min and their amount reduced, and α-CsPbBr3 nanocrystals appeared and grew with the reaction time extending to 30 min. Cs4PbBr6 nanocrystals disappeared, and α-CsPbBr3 NWs with a width of ∼20 nm and a length of ∼1 μm were obtained when the reaction reached 60 min. Further extending the reaction time resulted in self-assembling and growth of CsPbBr3 NWs, the width of CsPbBr3 wires reached ∼1 μm, and the length reached ∼100 μm when the reaction time was 24 h. TEM images clearly showed that CsPbBr3 NWs become wider and longer by self-assembly of CsPbBr3 nanocubes and NWs. A statistics study revealed that there is a linear relationship between the width and the reciprocal of time. The self-assembly CsPbBr3 perovskite NWs presented a high-intensity green PL around 519 nm and high PL quantum yield, which was 71.7, 76.9, 64.9, and 39.5% for the samples reacted for 10, 30, 60, and 180 min, respectively, under 375 nm laser irradiation, and the photocarrier lifetime for the sample with 180 min can reach 25.79 ns. The obtained CsPbBr3 NWs have few defects and produce less recombination during the photoemission process, which is promising for applications in the fields of optoelectronic devices, especially photodetectors, lasers, and solar cells devices.
User Preferences between Keyboards while Performing “Real” Work: A Comparison of “Alternative” and Standard Keyboards

Field: Health Professions (Health Sciences)

The proliferation of varying computer keyboard designs may pose problems to those who specify, purchase and ultimately use such devices. Are any of them “best” for my work? Will actual users derive any benefit from them? To assist in addressing such issues, we explored an approach to determining if any of three “alternative” keyboards provided a benefit to employees by increasing user comfort. A total of 34 employees participated in this study, each using an “alternative” keyboard for one week at a time while performing their actual work. After using each keyboard, including their standard “101” keyboard, subjects completed a questionnaire of seven psychophysical measures relating to the comfort and use of the keyboard. Questionnaire responses were tabulated and a Repeated Measures Analysis of variance conducted. Statistically significant differences were found among and between the four keyboards on four of the seven psychophysical measures. Overall results showed little differences in user assessments between three of the keyboards, with the fourth keyboard assessed less favorably when significant differences were found. The results suggest that user assessments can produce significant results between keyboards, and that no one “best” keyboard exists for any given set of tasks and group of users.
Validated Method for Strigolactone Quantification by Ultra High‐Performance Liquid Chromatography – Electrospray Ionisation Tandem Mass Spectrometry Using Novel Deuterium Labelled Standards

Field: Agricultural and Biological Sciences (Life Sciences)

Abstract Introduction Strigolactones (SLs) are important plant hormones. They are difficult to analyse because they occur in very small concentrations especially in comparison with other plant hormones and other substances can interfere with their detection. Objective To develop a procedure for the extraction, purification and quantification of SLs from plant roots. Methodology Samples were prepared by extraction of plant root tissues with ethyl acetate. Then the extracts were further purified with silica column chromatography. The natural SLs in the final extracts were quantified using novel deuterium labelled SLs. The results of the methodology were compared with those of the procedure of Yoneyama and coworkers. Results This procedure required about 1‐g root samples to detect and quantify simultaneously the SLs (orobanchyl acetate and fabacyl acetate) concentration with high reliability. Conclusion A method was developed for determining endogenous fabacyl acetate and orobanchyl acetate in plant tissue based on novel deuterium labelled standards. A method of orobanchol quantification using a synthetic SL GR24 as internal standard was proposed. Copyright © 2017 John Wiley & Sons, Ltd.
Ustekinumab in the therapy of chronic plaque psoriasis

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Psoriasis is a chronic inflammatory disorder characterized by T cell dysregulation and a chronic inflammatory infiltrate within the epidermis. Several cytokines play an important role in the pathogenesis of psoriasis, including interleukin-12 (IL-12) and IL-23. These cytokines act via induction of pro-inflammatory cytokines which promote chronic inflammation and auto-reactivity. Ustekinumab is a fully human monoclonal antibody against the common p40 subunit of IL-12 and IL-23. Two randomized, double-blind, placebo-controlled trials of ustekinumab have demonstrated significant and prolonged efficacy in the treatment of plaque psoriasis. Adverse events were generally similar across treatment and control groups. Studies are ongoing to assess the long term safety and efficacy profiles of ustekinumab.

Numerical investigation of transient responses of triangular fins having linear and power law property variation under step changes in base temperature and base heat flux using lattice Boltzmann method

Field: Engineering (Physical Sciences)

In this article, transient response of triangular longitudinal fin with internal heat generation under step change in (i) base temperature and (ii) base heat flux assuming is reported. The convection coefficient is assumed to be power law function of temperature, accounting for different practical application. Moreover, thermal conductivity and heat generation coefficient are assumed as linear and power law functions of temperature. The nonlinear differential equation of triangular fins is solved using Lattice Boltzmann method (LBM) with the aid of in-house MATLAB code. Till date, transient response of triangular fins with linear temperature dependence are only reported, under the step change in base temperature. Further, internal heat generation under the step change in base heat flux with power law temperature dependent properties for fins have been rarely reported. The results are first validated with available benchmarks and subsequently results for different thermal and geometry parameter are reported in graphical form.
A* Based Routing and Scheduling Modules for Multiple AGVs in an Industrial Scenario

Field: Computer Science (Physical Sciences)

A multi-AGV based logistic system is typically associated with two fundamental problems, critical for its overall performance: the AGV’s route planning for collision and deadlock avoidance; and the task scheduling to determine which vehicle should transport which load. Several heuristic functions can be used according to the application. This paper proposes a time-based algorithm to dynamically control a fleet of Autonomous Guided Vehicles (AGVs) in an automatic warehouse scenario. Our approach includes a routing algorithm based on the A* heuristic search (TEA*—Time Enhanced A*) to generate free-collisions paths and a scheduling module to improve the results of the routing algorithm. These modules work cooperatively to provide an efficient task execution time considering as basis the routing algorithm information. Simulation experiments are presented using a typical industrial layout for 10 and 20 AGVs. Moreover, a comparison with an alternative approach from the state-of-the-art is also presented.

Effect of Incarcerated HF on the Chemical Reactivity of Endohedral HF@C60

Field: Chemistry (Physical Sciences)

The first chemical modification on the endohedral HF@C60 is reported. In particular, the isomerization from optically pure (2S,5S)-cis-pyrrolidinofullerene 2b to (2S,5R)-trans-pyrrolidinofullerene 2b has been studied and compared with empty C60 (2a) and endo-hedral H2O@C60 (3). Interestingly, the incarcerated HF molecule contributes to increase the isomerization rate through a H-bonding assistance involving weak hydrogen bonding without affecting the final cis-trans ratio or promoting the loss of enantioselective control through the retro-cycloaddition reaction. The comparative study shows a kinetic order for the isomerization process of H2O@C60 ˃ HF@C60 ˃ C60, thus confirming the effect of the incarcerated species on the zwitterionic intermediate stability
Music in Early Twentieth-Century Istanbul

Field: Arts and Humanities (Social Sciences)

This study addresses the social history of music in early twentieth-century Ottoman Istanbul. The paper argues that private music schools were at the center of transformations in music and that their history is profoundly related to the political crises the Ottoman state experienced after the turn of the twentieth century. More precisely, by approaching the Ottoman bureaucracy from a musical perspective, the paper tries to link the reorganization of the Ottoman bureaucracy in 1909 with the emergence of private music schools in Istanbul. To explore the process, the paper follows some official functionaries’ career paths to explain their concentration in these schools. In contrast to conventional historiography, the aim is to emphasise that out of the political crises, private music schools emerged as a new ground in music. By paying limited attention to musical aspects, the study will mainly address the social roles these schools occupied in Ottoman urban life. They were practically social organizations, whose members pursued common goals. Collective action, such a fundamental shift of mindset on the part of the musicians, facilitated the advancement of the status of musicians in Ottoman urban society and decreased uncertainty about the future of the profession. Moreover, the institutional identity provided by the schools changed the place of women in music by increasing their visibility as music teachers and performers.
