Factors determining the public receptivity regarding waste sorting: a case study in Surabaya city, Indonesia
Authors: Setiawan Rulli Pratiwi 
Published: January 2020

AbstractWaste sorting at the source has been enforced by the Government of Indonesia since the implementation of the Waste Management Law No. 18 Year 2008. However, waste sorting is still not a popular practice in households. We present the findings of a survey conducted for 900 households’ receptivity regarding waste sorting at the source. A logistic regression model allowed us to examine the socio-economic characteristics determining the public receptivity regarding waste sorting at the source. The results show that household heads’ years of education, family members, current sorting practices and understanding of sorting obligations, are the factors determining the public receptivity regarding waste sorting at the source. Moreover, we also assessed the main reasons why households have not practiced waste sorting at the source yet. The three main reasons are mixed collection and transport (26%), lack of sorting facilities (23%), and lack of time (22%). The findings provide useful insight for the local government in developing mechanisms for the implementation of waste sorting at the source on larger scales as a part of the waste reduction program.

PURPOSE The aim of the current study was to determine patient-reported functional outcomes in men with prostate cancer (PCa) undergoing moderately hypofractionated (H-RT) or conventionally fractionated radiation therapy (C-RT) in a national cohort study. PATIENDS AND METHODS All men diagnosed with PCa between April 2014 and September 2016 in the English National Health Service undergoing C-RT or H-RT were identified in the National Prostate Cancer Audit and mailed a questionnaire at least 18 months after diagnosis. We estimated differences in patient-reported urinary, bowel, sexual, and hormonal function—Expanded Prostate Cancer Index Composite short-form 26 domain scores on a 0 to 100 scale—and health-related quality of life—EQ-5D-5L on a 0 to 1 scale—using linear regression with adjustment for patient, tumor, and treatment-related factors in addition to GI and genitourinary baseline function, with higher scores representing better outcomes. RESULTS Of the 17,058 men in the cohort, 77% responded: 8,432 men received C-RT (64.2%) and 4,699 H-RT (35.8%). Men in the H-RT group were older (age ≥ 70 years: 67.5% v 60.9%), fewer men had locally advanced disease (56.5% v 71.3%), were less likely to receive androgen-deprivation therapy (79.5% v 87.8%), and slightly more men had pretreatment genitourinary procedures (24.2% v 21.2%). H-RT was associated with small increases in adjusted mean Expanded Prostate Cancer Index Composite short-form 26 sexual (3.3 points; 95% CI, 2.1 to 4.5; P < .001) and hormonal function scores (3.2 points; 95% CI, 1.8 to 4.6; P < .001). These differences failed to meet established thresholds for a clinically meaningful change. There were no statistically significant differences in urinary or bowel function and quality of life. CONCLUSION This is the first national cohort study comparing functional outcomes after H-RT and C-RT reported by patients. These real-world results further support the use of H-RT as the standard for radiation therapy in men with nonmetastatic PCa.

Published: January 2020

Abstract

Context
Severe energy deprivation markedly inhibits erythropoiesis by restricting iron availability for hemoglobin synthesis.

Objective
The objective of this study was to determine whether testosterone supplementation during energy deficit increased indicators of iron turnover and attenuated the decline in erythropoiesis compared to placebo.

Design
This was a 3-phase, randomized, double-blind, placebo-controlled trial.

Setting
The study was conducted at the Pennington Biomedical Research Center.

Patients or Other Participants
Fifty healthy young males.

Intervention(s)
Phase 1 was a 14-day free-living eucaloric controlled-feeding phase; phase 2 was a 28-day inpatient phase where participants were randomized to 200 mg testosterone enanthate/week or an isovolumetric placebo/week during an energy deficit of 55% of total daily energy expenditure; phase 3 was a 14-day free-living, ad libitum recovery period.

Main Outcome Measure(s)
Indices of erythropoiesis, iron status, and hepcidin and erythroferrone were determined.

Results
Hepcidin declined by 41%, indicators of iron turnover increased, and functional iron stores were reduced with testosterone administration during energy deficit compared to placebo. Testosterone administration during energy deficit increased circulating concentrations of erythropoietin and maintained erythropoiesis, as indicated by an attenuation in the decline in hemoglobin and hematocrit with placebo. Erythroferrone did not differ between groups, suggesting that the reduction in hepcidin with testosterone occurs through an erythroferrone-independent mechanism.

Conclusion
These findings indicate that testosterone suppresses hepcidin, through either direct or indirect mechanisms, to increase iron turnover and maintain erythropoiesis during severe energy deficit. This trial was registered at www.clinicaltrials.gov as #NCT02734238.

Published: January 2020

Abstract

Context
Discontinuation of denosumab leads to a rapid reversal of its therapeutic effect. However, there are no data regarding how unintended delays or missed injections of denosumab impact bone mineral density (BMD) response.

Objective
We examined the association of delays in injections of denosumab with BMD change.

Design
We used electronic medical records from two academic hospitals from 2010 to 2017.

Participants
Patients older than 45 years of age and used at least 2 doses of 60 mg denosumab. Denosumab adherence was evaluated by the medication coverage ratio (MCR). Good adherence corresponds to a dosing interval ≤7 months (defined by MCR ≥93%), moderate adherence corresponds to an interval of 7 to 10 months (MCR 75%–93%), and poor adherence corresponds to an interval ≥10 months (MCR ≤75%).

Outcome Measures
Annualized percent BMD change from baseline at the lumbar spine, total hip, and femoral neck.

Results
We identified 938 denosumab injections among 151 patients; the mean (SD) age was 69 (10) years, and 95% were female. Patients with good adherence had an annualized BMD increase of 3.9% at the lumbar spine, compared with patients with moderate (3.0%) or poor adherence (1.4%, P for trend .002). Patients with good adherence had an annualized BMD increase of 2.1% at the total hip, compared with patients with moderate (1.3%) or poor adherence (0.6%, P for trend .002).

Conclusions
A longer interval between denosumab injections is associated with suboptimal BMD response at both spine and total hip. Strategies to improve the timely administration of denosumab in real-world settings are needed.
Frequency tracking out-of-lock control in a resonator fiber-optic gyro

Published: January 2020

A resonator fiber-optic gyro (RFOG) is being pursued because of its theoretical potential to meet navigation-grade performance with small size, high precision, and lower cost. The stability of the RFOG operation is based on the synchronization of laser frequency to the fiber ring resonator (FRR) resonance frequency. Frequency tracking out-of-lock will lead to peak pulse and zero-bias change at the output of the RFOG, which seriously degrades the performance. First, the influence mechanism of frequency tracking out-of-lock is analyzed. The change of current and temperature in frequency tracking and the symmetry change caused by backscatter and polarization are the main reasons for the peak pulse and zero-bias error. Second, a scheme of out-of-lock control of the RFOG based on temperature closed-loop operation using digital signal processing is proposed. The improved scheme, signal processing, and implementation method are investigated in detail. Finally, a RFOG prototype is assembled and tested, and 10 min tracking of the laser frequency to the FRR’s single-resonance frequency is realized by temperature closed-loop operation. The static performance of the RFOG over 1 h shows that the RFOG output errors caused by frequency tracking out-of-lock are successfully eliminated. The output peak pulse is reduced from 3000 to 200 deg/h, the zero bias is eliminated from 50 to 600 deg/h to 0, and the bias stability of the RFOG is improved from 15.2 to 1.85 deg/h, which indicates a remarkable advance in the performance of the RFOG to satisfy civil navigation application requirements.
Designing a multi-quantum-dot-doped wavelength down-shifting model of c-Si solar cells by using machine learning
Authors: Ren Binjie , Jiang Chun 
Published: January 2020

The efficiency of solar cell energy conversion may be significantly improved by better exploitation of the original solar spectrum. In this paper, we propose a multi-quantum-dot-doped wavelength down-shifting (WDS) model that can reduce the energy loss resulting from the mismatch between the solar spectrum and the solar cell material’s responsivity. The WDS layer can nearly perfectly absorb the photons in the range of 300 to 700 nm and then re-emit them at a longer wavelength. The distribution of quantum dots in the WDS layer is provided based on analysis of its spectral properties with a machine learning regression algorithm. Finally, the relationship between the optimizing ability of the model and the Stokes shift of the quantum dots is also discussed. Ideally, our model can provide up to 29% improvement to the external quantum efficiency of c-Si solar cells, which fully demonstrates the potential of our model.
Pore size assessment using gas in scattering media absorption spectroscopy and gas adsorption

Published: January 2020

Here, we investigate effects of the size of pores in porous alumina powders on the broadening of the oxygen gas absorption line. The line broadening is caused by collisions of oxygen molecules with the pore walls and is extracted using gas in scattering media absorption spectroscopy (GASMAS), while the average pore size is determined using the gas adsorption technique. The average pore size of the samples studied lies within the range 10–40 nm. In this range, the contribution of the wall collision broadening is found to be approximately inversely related to the average pore diameter. Furthermore, the confined oxygen gas absorbance measured by GASMAS is found to be linearly correlated with the effective porosity evaluated by the saturation method.

Authors: Lin Jing , Wu Su , Yu Lei 
Published: January 2020

An advanced optical design has been proposed for an astigmatism-free Offner imaging spectrometer with high resolution in the broadband spectrum. The anastigmatic theory is thoroughly analyzed. Astigmatism is corrected by two pairs of lens-mirror combinations. On the basis of the concentric structure, the lens is used to make the meridional image distance equal to sagittal image distance. An example of the design has been presented with f-number of 3 working in 400–1000 nm according to the optimized theory. By the ray-tracing results, the spectral sampling is 0.6nm/pixel, and the RMS spots radii in all fields of view are less than 5 µm. The spectral keystone distortion and smile distortion are less than 0.1%. The prototype is manufactured based on theory and tolerance analysis. The achieved prototype has advantages of high spectral resolution (3 nm) and compact configuration.

Published: January 2020

In this paper, we propose and demonstrate ultrafast Te nanorods as a saturable absorber (SA) for producing mode locking from an erbium-doped fiber laser for the first time, to the best of our knowledge. The Te nanorods were fabricated by a simple green chemical method with energy conservation and without a purification process. The morphology and structure measurements confirm uniform Te nanorods with a constant aspect ratio. The synthesized SA has a saturation intensity and modulation depth of

Published: January 2020

Monitoring energy in buildings can ease us to have a better understanding of electricity consumption patterns to support efficiency and avoid potential damages. However, indoor installations are mostly unmonitored because their panel meters are usually difficult to access. Yet, indoor maintenance tends to be more difficult since the cables are inside the wall, ceiling, or concrete. Internet of Things and big data analytics can be used to track electricity usage either in residential, commercial, or industrial buildings. This paper presents how a simple real-time energy data analytics was built at a low cost and high accuracy to inspect energy fluctuations, anomaly, and its significant pattern. We proposed 3 layers of architecture namely acquisition, transportation, and application management. An electronic module named PZEM004T was used to sense voltage, current, and other electrical parameters. Through a microcontroller ESP8266, the data was processed and sent it to an application layer via an existing wireless network. The actual and historical data of electricity were visualized on high-resolution graphs. The experiment was conducted at our office building. The experimental results showed that data of electrical energy usage can be captured close to realtime and power anomaly and pattern can be figured. Performance and functionality testing showed acceptable use of this system with more than 99% accuracy. This system is intended to empower building managers in evaluating the electrical network balance as well as anticipating damage due to overload, overvoltage, and voltage drop. If this model is widely implemented it will produce big data that is useful for advanced analysis.

Appropriate Pedagogy to Teach English: Contemporary Tendency Focusing on Non-Native
Authors: Dos Anjos Flávius Almeida 
Published: January 2020

This paper is about the teaching of English. It takes into account the global role this language gains today, to reflect on how it should be taught. The main objective of it is to defend a current tendency concerning the teaching of English. In the pursuit of an appropriate pedagogy to teach English, I propose the focus on non-native speaker, since we undestand that English is a world language, spoken by a great number of people, from different cultures, what has recreated this language in many aspects. That is why this language should not be only taught based on the hegemonic cultures. The reflection proposed here is, especially, anchored on Freire´s (1996) ideas on education, mainly when he defends learner’s autonomy. Thus, to teach English through an apropriate pedagogy, teachers should allow students to have ownership of it as well, but starting from a local perspective, avoiding, this way, bad feelings on the part of students.

Published: January 2020

Considering the vital role of comprehensible input, this study attempted to compare the effects of input with various difficulty levels on Iranian EFL learners’ reading comprehension and reading motivation. To fulfil this objective, 54 Iranian pre-intermediate EFL learners were selected from two intact classes (n = 27 each). The selected participants were randomly assigned to two equal groups, namely “i+1” (n=27) and “i-1” group (n=27). Then, the groups were pretested by a researcher-made reading comprehension test. After carrying out the pre-test, the treatment (i.e., extensive reading at different levels of difficulty) was practiced on the both groups. The participants in “i+1” group received reading passages beyond the current level, on the other hand, the “i-1” group received those reading passages which were below their current level. After the instruction ended, a modified version of pre-test was conducted as posttest to determine the impacts of the treatment on the students’ reading comprehension. The obtained results indicated that there was a significant difference between the post-tests of “i+1” and “i-1” groups. The findings showed that the “i+1” group significantly outperformed the “i-1” group (p < .05) on the post-test. Moreover, the findings indicated that “i+1” group’s motivation increased after the treatment. The implications of the study suggest that interactive type of input is beneficial to develop students’ language skills.
