The Effect of an Active Thermal Coating on Efficiency and Emissions from a High Speed Direct Injection Diesel Engine

This study looked into the application of active thermal coatings on the surfaces of the combustion chamber as a method of improving the thermal efficiency of internal combustion engines. The active thermal coating was applied to a production aluminium piston and its performance was compared against a reference aluminium piston on a single-cylinder diesel engine. The two pistons were tested over a wide range of speed/load conditions and the effects of EGR and combustion phasing on engine performance and tailpipe emissions were also investigated. A detailed energy balance approach was employed to study the thermal behaviour of the active thermal coating. In general, improvements in indicated specific fuel consumption were not statistically significant for the coated piston over the whole test matrix. Mean exhaust temperature showed a marginal increase with the coated piston of up to 6 °C. However, the normalised exhaust enthalpy showed a reduction (apart from the higher speed/load conditions when no EGR was applied). Energy transfer to the coolant was reduced by as much as 1.5 percentage points, in agreement with the expected reduction in piston heat transfer, across all operating conditions. Finally, soot emissions were increased with the coated piston, with the biggest differences between the coated and non-coated pistons observed at the lower speed/load conditions.
Are corporate social responsibility disclosures relevant for lenders? Empirical evidence from France

The purpose of this paper is to test whether or not CSR disclosure (i.e. aggregate as well as its three sub-indicators) reduces the cost of debt for French corporations listed in the SBF 120 index between 2010 and 2015. ,CSR disclosure ratings of firms were collected from the Bloomberg database under three dimensions such as environmental, social and governance (ESG). Then, a pooled regression analysis was run. ,The results indicate that overall CSR disclosure score as a combination of ESG disclosure scores has a negative effect on the cost of debt (i.e. lowers the cost of debt). While environmental disclosure is negatively associated with the cost of debt, social disclosure is unexpectedly positively associated, and governance disclosure has an insignificant association with the cost of debt. ,The study has two main limitations. First, the analysis does not consider contractual constraints and obligations that might exist in debt contracts (Jung et al., 2018). Second, the analyses cover a specific time period (i.e. between 2010 and 2015) for a specific country (i.e. France) excluding utilities and the financial sector. ,Overall, it is inferred from the results that financial markets for lenders take into account CSR disclosure when assessing the creditworthiness of borrowers. Specifically, environmental disclosure is the only subdimension of CSR that is influential on creditors’ decisions to offer favorable interest rates. In line with this outcome, companies can assess their processes and be more aligned with eco-friendly practices, and investors are particularly advised to invest in those types of firms. ,This study extends scant literature on the association between CSR and the cost of debt by exploring how creditors treat CSR dimensions dissimilarly in granting loans to firms. The findings of this study have particular importance as financial debt is one of the most predominant forms of external financing.
Durability of fiber boards made of jabon and andong bamboo with additional activated carbon additives against dry wood termites and subterranean termites

Utilization of wood waste as material to produce medium density fiber-board (MDF) will help to reduce the rate of deforestation. Jabon waste (Anthocephalus cadamba Miq.) combined with andong (Gigantochloa pseudoarundinacea (Steudel) Widjaja) bamboo waste with 50%:50% ratio were made into MDF with the size of 30 cm x 30 cm x 1.2 cm and density 0.45 kg/m3 and 0.55 kg/m3. Activated carbon additive 4% were then added in the process. MDF durability test towards attack from Cryptotermes cynocephalus Light dry wood termite and Coptotermes curvignathus Holmgrem subterranean termites were done according to SNI 01-7207-2014. Result shows that the addition of activated carbon powder increased the MDF’s dry wood termites-durability level from IV (not-durable) to III (moderately durable). Meanwhile, adding activated carbon powder additive in MDF had not increase its durability to subterranean termites attack. The MDF durability level against soil termite stood at the same level of IV (not-durable). Improvement needs to be done for MDF made of jabon and andong bamboo mix using preservatives to increase the MDF durability level.
Circular Dichroism in Low-Cost Plasmonics: 2D Arrays of Nanoholes in Silver

Arrays of nanoholes in metal are important plasmonic devices, proposed for applications spanning from biosensing to communications. In this work, we show that in such arrays the symmetry can be broken by means of the elliptical shape of the nanoholes, combined with the in-plane tilt of the ellipse axes away from the array symmetry lines. The array then differently interacts with circular polarizations of opposite handedness at normal incidence, i.e., it becomes intrinsically chiral. The measure of this difference is called circular dichroism (CD). The nanosphere lithography combined with tilted silver evaporation was employed as a low-cost fabrication technique. In this paper, we demonstrate intrinsic chirality and CD by measuring the extinction in the near-infrared range. We further employ numerical analysis to visualize the circular polarization coupling with the nanostructure. We find a good agreement between simulations and the experiment, meaning that the optimization can be used to further increase CD.
KEYNOTE-062: Phase III study of pembrolizumab (MK-3475) alone or in combination with chemotherapy versus chemotherapy alone as first-line therapy for advanced gastric or gastroesophageal junction (GEJ) adenocarcinoma.

TPS185 Background: Pembrolizumab (pembro) is a monoclonal antibody against PD-1 designed to block its interaction with PD-L1 and PD-L2 and permit an antitumor immune response. In KEYNOTE-012, pembro showed a 22% ORR (RECIST v1.1, central review) and a manageable safety profile in patients (pts) with advanced gastric cancer. The randomized, phase 3 KEYNOTE-062 study (NCT02494583) is designed to compare the efficacy and safety of pembro alone or in combination with cisplatin + a fluoropyrimidine with those of cisplatin + a fluoropyrimidine as first-line therapy for PD-L1+/HER2– advanced gastric or GEJ adenocarcinoma. Methods: Key eligibility criteria include age ≥ 18 y, locally advanced or metastatic PD-L1+/HER2– gastric or GEJ adenocarcinoma, ECOG PS 0-1, no active autoimmune disease or brain metastases, and no prior therapy for advanced disease. Pts are randomized 1:1:1 to pembro 200 mg Q3W (arm 1), pembro + cisplatin 80 mg/m2 Q3W + 5-fluorouracil (5-FU) 800 mg/m2 on days 1-5 of each Q3W cycle (arm 2), or.
Recommendations for Implementing the Distribution Policy, Price and Fertilizer Use Application

The government has a policy on subsidized fertilizer for farmers in Indonesia aimed at a more prosperous farmer's life. Government Regulation Number 77 of 2005 is the basis for determining that subsidized fertilizers are goods under supervision and then refined into Government Regulation No. 15 of 2011 contains the importance of regulations to regulate the issue of procurement and distribution of subsidized fertilizer to farmers because of irresponsible parties who misuse the distribution of fertilizers[1][2]. Currently there are many irregularities even though there are already so it is necessary to conduct strict supervision for the distribution of subsidized fertilizer. Currently there are many irregularities even though there are already so it is necessary to conduct strict supervision for the distribution of subsidized fertilizer. Application is one that can be a solution to the occurrence of abuse, with the application that handles the distribution of subsidized fertilizers in accordance with government policy to reporting the distribution of fertilizers[3][4]. The purpose of this research is to equalize subsidized fertilizer and to minimize the scarcity of subsidized fertilizer and improve farmers' welfare[5]. Model V is the method used in this study, because Model V has advantages in representing concepts using formal language and the development of the waterfall method. This research was developed using the Object Oriented Programming (OOP) programming language, while the design uses Unified Modeling Language (UML)[6][7][8][9]. The research conducted resulted in the application of distribution and financial reporting, so that it can be used as a recommendation for policies in the distribution of subsidized fertilizers so that fraud and misuse in the distribution of fertilizers that occur can be minimized[10][11].

300-GHz InP HBT Quadrature VCO With Integrated Mixer

A 300-GHz quadrature voltage-controlled oscillator (QVCO) integrated with a pair of mixers based on an InP heterojunction bipolar transistor (HBT) technology has been developed. A super-harmonic coupling technique was applied to generate the quadrature signal in the QVCO. The oscillation frequency tuning range is 24.8 GHz (from 286.1 to 310.9 GHz), and the frequency range maintaining the quadrature operation (within ±10°) is 4.8 GHz (297.2–302.0 GHz). The maximum output power of the QVCO was measured as 0.46 dBm at 286.3 GHz. The measured phase noise is −91.4 dBc/Hz with 10 MHz offset at 294.2 GHz. The integrated QVCO-mixer consumes a dc power of 167.5 mW.
Modélisation numérique et rhéologie des milieux granulaires à particules fragmentables en vue d'application aux broyeurs à boulets

Une etape cruciale de la fabrication des combustibles nucleaires est le co-broyage des oxydes d'uranium et de plutonium pour obtenir une taille ciblee et un melange homogene de particules. Cependant, le changement de l'echelle du laboratoire a celle de la production reste essentiellement empirique. Le but de cette these de doctorat est de modeliser et caracteriser les ecoulements granulaires dans des tambours rotatifs et d'elucider les mecanismes de broyage de l'echelle des particules a celle du procede. A l'aide de simulations granulaires, et d'un critere de decohesion dynamique base sur la mecanique de la rupture, on etudie la fragmentation de partic- ules sous impact. La dissociation de ces particules se fait au niveau d'une tessellation en cellules sous-jacentes fragmentables. Les analyses developpees portent notamment sur : les proprietes d'ecoulements granulaires dans le regime de cascade en fonction des parametres du systeme; l'effet de la taille et du nombre de corps broyants sur le processus de broyage; l'evolution de la frag- mentation dans les ecoulements en tambour rotatif. Nos simulations revelent plusieurs relations bien definies entre differentes variables caracterisant l'ecoulement (profil de surface, epaisseur d'ecoulement, fluctuations de force, glissement aux parois), l'evolution de la taille des particules et les parametres du systeme (vitesse de rotation, taille du tambour, taux de remplissage). Ces travaux conduisent a la definition d'un parametre sans dimension qui peut etre utilise pour la mise a l'echelle des ecoulements dans les tambours tournants et les broyeurs a boulets.
R&D in Europe: Sector Decomposition of Sources of (in)Efficiency

Measuring the efficiency of research and development (RD the decomposition of the efficiency is done by separating the main variables of interest into the private, higher education, and government sectors; and the robustness of the results is evaluated, which is often ignored in the literature. The results of the analysis are discussed with possible directions for inefficient countries. The rankings provided in the empirical part of the study confirm previous findings on disparities between the European countries with respect to innovation and the R&D sector.
Improved Learning Design for Pre-Service Teacher in a Character Education Course

This study aimed to develop pre-service teachers' engagement in a character education course through new learning design of a RECE (Reflect, Engage, Collaborate and Elaborate) teaching model, in the Pancasila and Citizenship Education department of a university. RECE involve self-reflections and collaborative learning. The RECE active learning and teaching model was implemented to engage pre-service teachers in challenging classroom environments. The study was conducted with 65 pre-service teachers in their first year of study in a one semester character education course. Pre-service teachers in the study are prepared to become teachers of Pancasila and Citizenship lesson in high schools in Indonesia. The course aims to prepare pre-service teachers for future challenges they may have to deal with in relation to religion, nationalism, independence, working together, and integrity. This research used a qualitative method with the data collection of interviews, observations and document analysis. This research was divided into two phases: first, teaching model development and second, student engagement. The teaching model engaged pre-service teachers in current issues through collaboration and reflection. The results indicate that participants were motivated to engage in the course by reflecting on their learning, by using the higher-order thinking skills of critical and creative thinking, and by using collaboration and communication skills. The pre-service teachers were challenged to deliberate about critical issues and to solve problems that may impact positively on their role as future teachers.
PREVALENCE AND SEVERITY OF DYSMENORRHOEA AMONG SOME ADOLESCENT GIRLS IN A SECONDARY SCHOOL IN ACCRA, GHANA

Background Dysmenorrhoea is a common problem among the adolescent but it is unclear the extent to which adolescent girls in Ghana are incapacitated each month due to the severity of dysmenorrhoea. Objective The objective of this study was to determine the prevalence and severity of dysmenorrhoea in adolescent girls and its effect on class attendance. Setting: St Mary’s Senior Secondary School, Accra Methodology: Cross-sectional descriptive study using selfadministered questionnaire Results: The prevalence of dysmenorrhoea in 453 adolescent girls in this study was 74.4% (CI 95%, 72.5%76.3%). Primary dysmenorrhoea is usually the type of dysmenorrhoea suffered by adolescent girls, a characteristic age group 14-19 years of respondents in the study. The percentage distribution for the various degrees of severity of dysmenorrhoea in 453 adolescent girls was 18.1%, 37.5%, and 18.8% for mild, moderate and severe dysmenorrhoea respectively. About 9.5% of respondents with dysmenorrhoea had absented themselves from class at some time. Among those who had severe dysmenorrhoea, 35.3% had absented themselves from class at some time (p<0.0001). Conclusions: This study shows that dysmenorrhoea is common among girls of this Senior Secondary School in Accra, Ghana. The correct approach to management of adolescent girls with dysmenorrhoea can reduce the adverse impact of severe dysmenorrhoea on academic activities in the form of class absenteeism.
Recent Trends in the Daily Rainfall Regime in Southern West Africa

Extreme climate events, either being linked to dry spells or extreme precipitation, are of major concern in Africa, a region in which the economy and population are highly vulnerable to climate hazards. However, recent trends in climate events are not often documented in this poorly surveyed continent. This study makes use of a large set of daily rain gauge data covering Southern West Africa (extending from 10° W to 10° E and from 4° N to 12° N) from 1950 to 2014. The evolution of the number and the intensity of daily rainfall events, especially the most extremes, were analyzed at the annual and seasonal scales. During the first rainy season (April–July), mean annual rainfall is observed to have a minor trend due to less frequent but more intense rainfall mainly along the coast of Southern West Africa (SWA) over the last two decades. The north–south seasonal changes exhibit an increase in mean annual rainfall over the last decade during the second rainy season (September–November) linked by both an increase in the frequency of occurrence of rainy days as well as an increase in the mean intensity and extreme events over the last decade. The study also provides evidence of a disparity that exists between the west and east of SWA, with the east recording a stronger increase in the mean intensity of wet days and extreme rainfall during the second rainy season (September–November).
Urgent Need of Nutritional Strategy and Innovated Functional Foods for Athletes Health and Fitness

It is generally accepted that sports lead to both healthy bodies and minds, but what to eat is a problematic. The majority of young men and college students like to practice gymnastic and related sports for building their bodies. However they do not aware about the proper nutrition required to increase muscle mass without inducing negative health effect. In addition, athletes practicing different types of sports need special nutrition before, during and after training to be in a healthy state together with complete fitness and performance. Supplementation of special food products formulated by nutritionists may be the solution.
Extreme Stress and Investor Behavior: Evidence from a Natural Experiment

We use the 2008 Mumbai terrorist attacks as a natural experiment to examine how exposure to extreme stress affects financial decision making, as measured by investors’ stock trading activity and performance. We find that Mumbai investors trade less, perform worse, take longer time to react to corporate news announcement, are less likely to initiate trades on new stocks, and perform worse on familiar stocks compared with other traders. Collectively, our findings are most consistent with impairment of cognitive ability after exposure to prolonged and extreme stress.

English Learning and its Relationship with Homework in Primary Education

En el aprendizaje de un idioma intervienen muchos factores y los deberes para casa son una herramienta a tener en cuenta. Esta investigacion de caracter descriptivo y co- rrelacional tiene como objetivo estudiar y analizar variables que pueden tener relacion entre los deberes y el aprendizaje del Ingles en Educacion Primaria, para conocer y analizar la situacion y ofrecer propuestas de mejora. La muestra de estudio ha estado compuesta por 747 alumnos, 679 familias y 57 docentes de 4o, 5o y 6o de Educacion Primaria. Los informantes han respondido a tres cuestionarios construidos ad hoc. Entre las variables analizadas estan la dificultad percibida de los deberes, si hay necesidad de ayuda, la frecuencia, las califica - ciones y el esfuerzo empleado en los deberes. Entre los principales resultados se ha obtenido que a los deberes de Ingles se les dedica mas tiempo y son los mas dificiles para los alumnos, concluyendose que requieren de mas esfuerzo y ayuda. Esto se correlaciona con la dificultad que encuentran las familias para ayudar, haciendose necesarias orientaciones sobre los debe- res por parte de los docentes para reducir esta situacion de dificultad y en consonancia con otros estudios. Se concluye que es crucial como los deberes esten disenados para su optimo desarrollo de forma autonoma.
Nonthermal Motions in a Polar Coronal Hole Measured with Hinode/EIS during an on-Orbit Partial Solar Eclipse on 2017 August 21

We have performed a spectroscopic observation over the south polar coronal hole (PCH) with the Hinode Extreme-ultraviolet (EUV) Imaging Spectrometer (EIS) during an on-orbit partial solar eclipse. In this partial eclipse, the Moon passed through the EIS observing area that was set in the south PCH at the height of 0.9–1.4 solar radii. Using the lunar occultation, we have corrected for the scattered light contamination from bright regions of the Sun that is present in the dark PCH emission line profiles. The nonthermal width of the corrected emission line profile in the PCH increases from the limb toward the high-altitude corona. It has also been confirmed that the nonthermal width tends to decrease beyond ∼1.2 solar radii. These results are consistent with the model in which outward-propagating Alfvén waves start being dissipated at ∼1.2 solar radii, as previously reported. The reduced energy within ∼1.4 solar radii contributes to atmospheric heating and the initial acceleration for the solar wind in the low corona. The remaining energy flux at 1.4 solar radii may be dissipated in the distant corona and is sufficient to provide the additional acceleration required to drive the fast solar wind.
Analysis of Worker's Compensation Claims for the Cerebrovascular and Cardiovascular Diseases.

Objectives: This study was performed to provide fundamental data to judge whether or not cerebro and cardiovascular diseases are work-related, by comparing the characteristics between approved and non-approved cases among the worker’s compensation claims. Methods: We collected 12,309 cerebro and cardiovascular disease claims based on the worker’s compensation records of the Labor Welfare Corporation from 2000 to 2004. The approved and non-approved cases were analyzed according to factors such as the calendar year, industry, company size, occupation, gender, age group, classification of cerebro and cardiovascular diseases, fatality and underlying diseases. We used χ 2 -test and multivariate logistic regression for the analysis. Results: According to multivariate logistic regression, electricity gas and water supply (OR=4.18, 95% CI=1.43~12.17), construction (OR=2.39, 95% CI=1.22~4.69) and manufacturing (OR=2.10, 95% CI=1.08~4.07) industries had a higher approval rate than mining and quarrying industries. Service workers and sales & marketing department workers (OR=1.90, 95% CI=1.47~2.47), professionals (OR=1.83, 95% CI=1.50~2.23), technicians and associate professionals (OR=1.63, 95% CI=1.35~1.97) and legisla-tors and senior officials and managers (OR=1.62, 95% CI=1.24~2.12) had a higher approval rate than plant and machine operators and assemblers. Female workers had a higher approval rate (OR=1.31, 95% CI=1.13~1.53) than male workers. Cerebrovascular diseases had a higher approval rate (OR=2.75, 95% CI=2.42~3.13) than cardiovascular diseases. Fatal cases had a higher approval rate (OR=6.01, 95% CI=4.89~7.38) than surviving cases. The approval rate for intracerebral hemorrhage arising in the course of employment (COE) was signifi-cantly higher than that arising out of employment (AOE), suggesting the need to correct the approval criteria.
