AbstractBoth from the perspective of the individual and from a socioeconomic point of view (e.g., return to work), it is important to have an insight into the potential differences in recovery between posterior cruciate ligament retaining (PCR) and posterior stabilized (PS) total knee arthroplasty (TKA) implants. The primary aim of this study was to compare the speed of recovery of patient-reported outcome between patients with a PCR and PS TKA during the first postoperative year. The secondary aim was to compare the effect on range of motion (ROM). In a randomized, double-blind, controlled, single-center trial, 120 adults diagnosed with osteoarthritis of the knee were randomized into either the PCR or PS group. Primary outcome was speed of recovery of patient-reported pain and function, measured with the Western Ontario and McMaster Universities osteoarthritis index (WOMAC), with a follow-up of 1 year. Main secondary outcome measure was ROM. A generalized estimating equations (GEE) analysis was used to assess whether there was a difference over time between groups (“p-value for interaction”). Between 2008 and 2011, 59 participants received a PCR TKA (mean age, 70.3 years [SD = 7.7]; mean body mass index [BMI], 30.5 kg/m2 [SD = 5.4]) and 55 participants a PS TKA (mean age, 73.5 years [SD = 7.0]; mean BMI, 29.2 kg/m2 [SD = 4.4]). Six patients (two PCR and four PS) were excluded because of early drop-out, so 114 patients (95%) were available for analysis. In between group difference for total WOMAC score was −1.3 (95% confidence interval [CI]: −5.6 to 3.1); p-value for interaction was 0.698. For ROM, in between group difference was 1.1 (95% CI: −2.6 to 4.7); p-value for interaction was 0.379. These results demonstrated that there are no differences in speed of recovery of WOMAC or ROM during the first postoperative year after PCR or PS TKA.
A review of the major drivers of the terrestrial carbon uptake: model-based assessments, consensus, and uncertainties

Abstract
Terrestrial and oceanic carbon sinks together sequester >50% of the anthropogenic emissions, and the major uncertainty in the global carbon budget is related to the terrestrial carbon cycle. Hence, it is important to understand the major drivers of the land carbon uptake to make informed decisions on climate change mitigation policies. In this paper, we assess the major drivers of the land carbon uptake—CO2 fertilization, nitrogen deposition, climate change, and land use/land cover changes (LULCC)—from existing literature for the historical period and future scenarios, focusing on the results from fifth Coupled Models Intercomparison Project (CMIP5). The existing literature shows that the LULCC fluxes have led to a decline in the terrestrial carbon stocks during the historical period, despite positive contributions from CO2 fertilization and nitrogen deposition. However, several studies find increases in the land carbon sink in recent decades and suggest that CO2 fertilization is the primary driver (up to 85%) of this increase followed by nitrogen deposition (∼10%–20%). For the 21st century, terrestrial carbon stocks are projected to increase in the majority of CMIP5 simulations under the representative concentration pathway 2.6 (RCP2.6), RCP4.5, and RCP8.5 scenarios, mainly due to CO2 fertilization. These projections indicate that the effects of nitrogen deposition in future scenarios are small (∼2%–10%), and climate warming would lead to a loss of land carbon. The vast majority of the studies consider the effects of only one or two of the drivers, impairing comprehensive assessments of the relative contributions of the drivers. Further, the broad range in magnitudes and scenario/model dependence of the sensitivity factors pose challenges in unambiguous projections of land carbon uptake. Improved representation of processes such as LULCC, fires, nutrient limitation and permafrost thawing in the models are necessary to constrain the present-day carbon cycle and for more accurate future projections.
Generalized additive models fitting with autocorrelation for sea surface temperature anomaly data
Authors: Ananda S , Miftahuddin  
Published: July 2019

Abstract
Climatic conditions in Sumatra Island are affected by Sea Surface Temperature Anomaly (SSTA) in the Indian Ocean or more commonly referred to as Indian Ocean Dipole (IOD). Extreme climate events also closely related to SSTA. Several climate features that affect SSTA such as air temperature, precipitation rain, relative humidity, wind speed, and solar radiation. SSTA is an increase or decrease in the mean of Sea Surface Temperature so required the analysis to assess extreme climatic events to the risk due to the occurrence of anomalies. Generalized Additive Models (GAM) with autocorrelation can be used to model this phenomenon. GAM method accommodates the nonlinear influence between response variables and predictor variables. The data used in this research is the time series data, daily data from 2006-2017 and there are gaps in it, where there is an autocorrelation value. The purpose of this research is to get a representative model and to know the factors that influence to SSTA. The results show that GAM’s best model with autocorrelation is GAM model by including month and year variables with the monthly autocorrelation structure. Factors that affecting SSTA are the air temperature, month and year as time covariates.

Abstract
Agricultural and industrial products need a high performance of packaging that can preserve its properties in a long period. A high-performance bioplastic was developed in this study from wheat Janeng starch. The bioplastics were prepared by casting on the glass plate and formed by phase inversion method. Bioplastics are made from a mixture of starch and glycerol provides transparent films with high tensile strength and elongation value. The optimum bioplastics compositions were 12 % (w/w) of starch and 5 % (w/w) of glycerol as plasticizer. Glycerol was used as a plasticizer to modify its mechanical properties. The addition of glycerol with the concentration of 5 % (w/w) produced a bioplastic with a high tensile strength of 20.95 kgf/mm2 and 42.69 % of elongation. The bioplastics are made from janeng starch can be used for packaging apples and tomatoes slice with a high protective barrier.

Abstract
Aceh is the richest province in Indonesia in the context of diversity with the local rice varieties. Therefore, it requires conservation efforts within this issue. The weakness parameters of local rice are long-lived and low production. One of the technologies that are been used to obtain the characteristics of short-lived local rice and high production is by using gamma-ray irradiation technology. This research aims to know the quality of sensory evaluation with descriptive method on Aceh local rice Mutant M6 by gamma-ray irradiation. The Aceh local rice Mutant M6 that has been used in this study were I-CKU-6, UF1 B4-9-2017, O-SGP, O-10D, S-103, S-97, S-01 (conventional and organic cultivation), O-39 e, O-10 d, O-57 e (organic cultivation), S-97, S-84 dan UFi-B (conventional cultivation). The approach that has been used in this research was using Completely Randomized Design (CRD) non factorial with three replicates. The result showed that local rice with irradiated gamma-ray (M6) had a very significant effect on the flavour, color, texture, shape, and overall acceptance of rice by conventional and organic cultivation. The local rice O-SGP (5.82) is the local rice that has been received by panelists, followed by local rice S-103 (5.75), O-10D (4.95) and S-97 (4.70), while the aroma was favored by panelists is O-SGP (4.92). The S-84 local rice which was grown conventionally was preferred by panelists with a value of 9.85.

Published: July 2019

Abstract
The unit price of work is the price required to complete each unit of quantity of work that consists of the unit price for the wage of labour, materials, and equipment used. Changes in unit prices are possibly determined by the different sites in which a building is constructed. For budget planners or construction executors, a good understanding of the changes in the unit price of work is required to identify the reasonable amount of budget needed. Given these circumstances, this study was conducted to analyse and identify the pattern of changes in the unit price of work based on the locations of a building in the Province of Aceh. This research focuses on the unit price of reinforced concrete work for the building structure components, as the work that has the most significant proportion of cost in building construction. The pattern of change is described in the form of price indexes by applying the price in Banda Aceh City as a reference for other cities/districts. The analysis results in two patterns of the unit price index, which is below or above of the reference index. This condition follows the pattern of the unit price of materials and wages. The ease of access to a region also determine the changes in the price index.
The potential utilization of natural materials as a wall covering of the building in heat reduction
Authors: Jeumpa K 
Published: July 2019

Abstract
This paper aims to examine the potential of natural coco fibre to be utilized as a wall covering in building construction for sun radiation protection. Engineering innovation in building construction to control the building’s temperature is important. Lowering the building’s room temperature can be carried out by modifying the wall construction materials. Thus, the usage of an air conditioner which is not environmentally friendly can be reduced. The wall modification can give more protection and dampen the sun’s heat, hence the thermal comfort can be obtained. Natural materials, moreover, can be used in the wall modification to reduce the room temperature. In this study, a comparative analysis was carried out between two materials: (1) the coco fibre coated with cement mixture; (2) the mixture of cement and sand, both were used as materials to plaster the wall. The cement mixture acted to bind the compacted coco fibre sheets. The material was evaluated after the cement mixture had been hardened. The test was carried out by providing heat on one side and measuring the temperature on the other side of the material. The results were significant between the two materials. This indicates the potential of coco fibre as a heat insulation in the wall construction materials that can minimize solar thermal radiation into the room.

Abstract
Land transportation still becomes a vital role in human and material mobility to date. In developing countries, like Indonesia, the development of land transportation infrastructure is growing very fast, but the level of road damage is also still quite high. Therefore, road users need information on road conditions that will be passed. This research proposes the use of openstreetmap data to develop spatial data of road conditions dynamically and inexpensively, because it is open access and free editable. The focus is to design spatial data of road conditions and to present a visualization of road condition maps based on Openstreetmap. The raw data will be exported to the Spatial Database Management Systems (SDBMS) and then redesigned the data so that the system can add the status of road condition on each road segments. The result is a system design that can store spatial data and present a visualization of the road condition map. With this system, anyone can update the condition data of a road and can access the road condition map through the web and mobile applications.

Published: July 2019

Abstract
As a major tourist destination in Indonesia, Bali possesses hospitality industries that are competing to present the best experience for guests. One of the hotels, Katamama, offers a specific spatial experience through the use of Bata Pejaten, handmade bricks traditionally made from mixtures of clay and paras sand—a fine stone powder of volcanic material sourced locally in Bali. Meticulous selection of Bata Pejaten applied on the 5-star quality hotel became its own uniqueness as these bricks are generally seen as a simple inexpensive material and mainly used for temples construction. As an interior space, it should be recognized not only related to the usability to meet human needs, but also the emotional effect of giving experience. Those spatial experiences are the atmosphere of space that exists between human and their built environment. It is understood through the senses of human, creating an impression and significant meaning to the person. In this case, the material becomes one of the important aspects of spatial atmosphere production. For Bata Pejaten, it is their craftsmanship, composition, and organic transformation. The paper aims to explore how Bata Pejaten and its properties and qualities generate atmosphere of space. This paper presents a case study analysis on interior spaces characterized by its specific material and authentic substances from volcanic eruptions as the core investigation. This paper demonstrates a design approach from the material perspective. In particular, this study introduces the concept of using materials attentively in creating spatial atmosphere characterized by modest material yet rich in its values.

Published: July 2019

Abstract
The purpose of this study is to investigate the relationship between data skewness in the output variable and the accuracy of artificial neural network predictive model. The artificial neural network predictive model is built using multilayer perceptron and consist of one output variable and six input variable, and the algorithm used is back propagation. Data used in this study is generated by conducting the simulations in 1000 cycles. Three categories of skewness used in the output variables are positive skewness, neutral, and negative skewness. The results show that data skewness does not have a significant effect on the accuracy of the artificial neural network predictive model. These results imply that artificial neural network predictive model has a higher capability to cope with skewed data due to its complexity in the hidden layer.

Published: July 2019

Abstract
Nowadays, Energy is an essential requirement for daily activities. Indonesians use solar energy for various activities such as electricity, water heaters, and dryers. Solar collectors are devices that absorb solar energy and convert it into heat energy. Solar energy heats copper pipes and water passes through heat tubes induces an increase in water temperature. The increase in heating capacity in this experiment was carried out by adding paraffin (as thermal storage material) into a tube in a solar collector. Solar water heaters equipped with solar collectors (called cylindrical trough collectors) have been developed in this experiment. Paraffin placed in the copper tube with two conditions. They are called Collector A and Collector B. The effect of two conditions of placing paraffin in copper tubes on the water-out temperature has been studied in this experiment. The result shows that the highest water temperature found with 56°C in collector A. It is due to the highest solar radiation intensity also record at 1,289 W/m2 (1:00 PM). While Collector B only produces the water-out temperature of 52°C at 1:00 PM. The conclusion shows that the position of paraffin in tubes with Collector A can increase the water-out temperature in the solar water heating system if compared with the collector.

Published: July 2019

Abstract
Photoluminescence (PL) measurements were carried out on 0.5-μm thick BaSi2 epitaxial films grown on Si(111) substrates with various Ba-to-Si deposition rate ratios (R
Ba/R
Si) in the range of 1.7–5.1. The samples were excited from both the frontside (BaSi2) and the backside (Si substrate), at temperatures in the range of 8–50 K. These measurements have highlighted the existence of localized states within the bandgap that result from defects in the BaSi2 films. The PL intensity is highly dependent on the excitation power, temperature, and R
Ba/R
Si. Of those studied, the BaSi2 film at R
Ba/R
Si = 4.0 showed the most intense PL and weak photoresponsivity, whereas the PL intensity was weaker for the other samples. Therefore, we chose this sample for a detailed PL investigation. Based on the results we determined the energy separation between localized states, corresponding to PL peak energies. The difference in PL spectra excited from the BaSi2-side and Si-side is attributed to the difference in kinds of defects emitting PL. The photoresponsivity of the BaSi2 was drastically enhanced by atomic hydrogen passivation, and the PL intensity of the sample decreased accordingly.
The Unspeakable Speculative, Spoken
Authors: Wanzo Rebecca 
Published: July 2019

AbstractExploring various absences—what is or should not be represented in addition to the unspeakable in terms of racial representations—is the through line of three recent books about race and speculative fictions. Mark C. Jerng’s Racial Worldmaking: The Power of Popular Fiction (2018) argues racial worldmaking has been at the center of speculative fictions in the US. In Posthuman Blackness and the Black Female Imagination (2017), Kristen Lillvis takes one of the primary thematic concerns of black speculative fictions—the posthuman—and rereads some of the most canonical works in the black feminist literary canon through that lens. Lillvis addresses a traditional problem in the turn to discussions of the posthuman and nonhuman, namely, what does it mean to rethink black people’s humanity when they have traditionally been categorized as nonhuman? Sami Schalk’s Bodyminds Reimagined: (Dis)ability, Race, and Gender in Black Women’s Speculative Fiction (2018) speaks to the absence of a framework of disability in African American literature and cultural criticism. In addressing absence—or, perhaps silence—Schalk offers the most paradigm-shifting challenge to what is speakable and unspeakable: the problem of linking blackness with disability and how to reframe our treatment of these categories.
Lyric Reading Revisited: Passion, Address, and Form in Citizen
Authors: Skillman Nikki 
Published: July 2019

AbstractThis article makes the case for a revised model of lyric reading. While theorists have thus far identified lyric reading with a monolithic, expressive model of lyric, the more capacious model I propose involves bringing the signature entanglements that have endowed the term lyric with historical freight and analytical richness to bear on the analysis of literary works—particularly on generically ambiguous contemporary works written during the era of what Virginia Jackson and Yopie Prins have called “lyricization.” The essay presents three recurring sites of debate in lyric theory, using each to bring distinct aesthetic and political dimensions of Claudia Rankine’s Citizen: An American Lyric (2014) into focus. Meditating on contested, rather than putatively universal, features of lyric and their imprint upon Rankine’s “American lyric” reveals the urgent matters of value that such features comprehend. To explore them is to explore the racial subconscious of the lyric tradition and recover how lyric has been multiply and alternatively conceived.

Abstract

Background
Standardization of performance-based physical function measures that are reliable and responsive to intervention is necessary for efficacy trials of function promoting anabolic therapies (FPTs). Herein, we describe a standardized method of measuring stair climbing power (SCP) and evaluate its ability to assess improvements in physical function in response to an FPT (testosterone) compared to gait speed.

Methods
We used a 12-step SCP test with and without carrying a load (loaded, LSCP or unloaded, USCP) in two testosterone trials in older men. SCP was determined from mass, total step-rise, and time of ascent measured with an electronic timing system. Associations between SCP and leg press performance (strength and power), testosterone levels, and gait speed were assessed. Test–retest reliability was evaluated using interclass correlation and Bland–Altman analyses.

Results
Baseline SCP was negatively associated with age and positively with leg strength and power and gait speed. Both tests of SCP were safe and showed excellent reliability (intra-class correlation 0.91–0.97 in both cohorts). Changes in testosterone concentrations were associated with changes in USCP and LSCP, but not gait speed in mobility-limited men. Changes in leg press performance were associated with SCP in both trials.

Conclusions
Both USCP and LSCP are safe and have high test–retest reliability. Compared to gait speed, SCP is associated more robustly with leg press performance and is sensitive to testosterone therapy. The LSCP might be a more responsive outcome than gait speed to evaluate the efficacy of FPT in randomized trials.
