ENGKLEK GEN 4.0 (Studi Etnomatematika : Permainan Tradisional Engklek sebagai Media Pembelajaran Matematika)

Apabila kita mendengar kata tradisional pastilah kita membayangkan masa lalu, kebanyakan orang jaman sekarang yaitu generasi 4.0 (sebuah masa dimana semua orang sudah mulai tergantung dengan teknologi) mudah melupakan adat istiadat atau kebiasaan dan budaya dari masa lalu atau masa kecil kita. Semakin berkembanganya teknologi di masa sekarang sangat berpengaruh menghilangkan nilai-nilai terhadap kebiasaan atau budaya yang sudah ada sejak dahulu. Padahal, tidak semua hal yang berhubungan dengan masa lalu tidak berguna untuk masa sekarang. Dalam proses pembelajaran matematika kita dapat menhubungkan matematika dengan seni atau biasa disebut dengan etnomatematika. Dalam etnomatematika kita dapat menggunakan media pembelajaran yang berasal dari budaya jaman tradisional, seperti permainan tradisonal dalam menunjang kegiatan pembelajaran yang bersifat edukatif, menyenangkan dan menarik perhatian siswa. Salah satu contoh permainan tradisional yang dapat diterapkan pada generasi 4.0 adalah permainan tradisional engklek. Karena, didalam permainan tradisional engklek mengandung nilai-nilai yang positif dan bermanfaat, salah satunya sebagai pengembangan media pembelajaran. Dengan kita menggunakan permainan tradisional sebagai media pembelajaran masa sekarang, itu berarti kita secara tidak langsung juga ikut melestarikan budaya tradisional bangsa Indonesia.
Recommendations for Healthy Daytime, Evening, and Night-Time Indoor Light Exposure

Ocular light exposure has important influences on human health and well-being through modulation of circadian rhythms and sleep, as well as neuroendocrine and cognitive functions. Current patterns of light exposure do not optimally engage these actions for many individuals, but advances in our understanding of the underpinning mechanisms and emerging lighting technologies now present opportunities to adjust lighting to promote optimal physical and mental health and performance. A newly developed, SI-compliant standard provides a way of quantifying the influence of light on the intrinsically photosensitive, melanopsin-expressing, retinal neurons that mediate these effects. The present report provides recommendations for lighting, based on an expert-scientific consensus and expressed according to this new measurement standard. These recommendations are supported by a comprehensive analysis of the sensitivity of human ‘non-visual’ responses to ocular light, are centred on an easily measured quantity (melanopic equivalent daylight (D65) illuminance), and provide a straightforward framework to inform lighting design and practice.
Iron Age peat cutting and ritual depositions in bogs – new evidence from Fuglsøgaard Mose, Denmark

With the discovery of peat and gyttja deposits containing archaeological remains, sealed below colluvium, at Fuglsøgaard in eastern Jutland came a rare opportunity to investigate an Iron Age votive bog with abundant traces of peat cutting and subsequent ritual deposition. Pollen analyses show that before, during and after the votive phase, the bog lay in an open cultural landscape surrounded by arable fields and pastures. Around 180 BC, extensive peat extraction commenced in the bog, targeting the well-humified wood peat that could be found in the deeper layers. It is estimated that 250-500 m2 of peat was removed, leaving the bog with numerous small water-filled pits, i.e. peat cuts. These water-filled peat cuts then had a secondary role as elements in votive activities in which ritual depositions were made of pottery vessels, parts of domestic animals, wooden objects, bundles of flax, quantities of white/light-coloured stones etc. More than 130 pottery vessels from period II of the Pre-Roman Iron Age (250-1 BC) have been excavated at the site. All the depositions included white/light-coloured stones, and these appear to have been a general feature of many ritual depositions in votive bogs at this time.
Adaption of COBRA Method for The Investigation of Nutrition-Based DNA Methylation Mechanism in Escherichia coli

Epigenetics are changes that occur in the DNA sequence due to environmental conditions. In last few decades epigenetics has been one of the most important advances in biology and related fields. It is very important in that it offers a new approach to all relevant disciplines, especially biology, to explain how DNA sequencing in an epigenetic organism is affected by environmental conditions and phenotype changes that may result from this interaction. Although there are many environmental factors affecting organisms, starvation is one of the most important factors. In our study, epigenetic changes in Escherichia coli due to carbon starvation in the sprE (rssB) gene region were investigated by COBRA (Combined Bisulfite Restriction Analysis) technique, which is one of the quantitative methylation analyzes. As a result of the current results, it has been shown that the methylation status of the 16th CpG islet located in the sprE gene region does not play a role in the regulation of fasting metabolism in E. coli due to the restriction of the carbon level.
Morphology and Thermal Behavior of MCPA6/SAN Blends Prepared by Anionic Ring-Opening Polymerization of ε-caprolactam

SummaryIn this article, a series of blends of monomer casting polyamide 6 and styrene-co-acrylonitrile (MCPA6/SAN) were prepared by in situ anionic ring-opening polymerization of ε-caprolactam (CL). Their morphology and thermal behaviors were investigated by means of scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and wide-angle x-ray diffraction (WAXD), respectively. The SAN phase had much finer domain in MCPA6/SAN than that in the polyamide6/SAN (PA6/SAN) blends prepared by melt blending of PA6 and SAN. All the melting and crystallization parameters of MCPA6/SAN blends decreased gradually with the increase of SAN content, while the melting temperature was almost unchanged. These results were due to the hydrolysis reaction of SAN occurred during the anionic polymerization of ε-caprolactam (CL). In addition, WAXD results showed that only α crystal forms existed in the MCPA6/SAN blends.
Synthesis of porous In2O3 microspheres as a sensitive material for early warning of hydrocarbon explosions

Efficient detection/monitoring of low-concentration C1–C3 aliphatic hydrocarbons (e.g., methane) is a challenging task, mainly due to their intrinsically low chemical reactivity and thereby weak sensing response. Herein we report the template-free synthesis of porous nanoparticle-assembled In2O3 microspheres that can serve as a highly sensitive material for C1–C3 detection. In particular, porous In2O3 microspheres with a BET surface area of 57 m2 g−1 are prepared through simple thermal treatment of an indium glycerolate precursor. The gas-sensing properties of the porous In2O3 material are evaluated by a series of C1–C3 hydrocarbons including methane (CH4), ethane (C2H6), propane (C3H8), ethylene (C2H4) and acetylene (C2H2). The porous In2O3 material has the ability to detect these gases with a rapid response (<10 s) in a wide concentration range from 200 ppm to 50 000 ppm (the lower explosion limit of methane). In the testing range, the logarithm of response shows a good linear dependency on the logarithm of gas concentration, demonstrating that the porous In2O3 material may be used for quantitative detection of C1–C3 hydrocarbons. Given the rapid response and high sensitivity below the explosion limit, this porous In2O3 material is promising to provide earlier warning against the explosion risk of hydrocarbon compounds.
Balancing the carbon budget. Implications for projections of future carbon dioxide concentration changes

A carbon cycle model is described incorporating CO 2 fertilization feedback and a convolution ocean model that allows the atmosphere-to-ocean flux to be varied. The main parameters controlling the model's behaviour are a fertilization feedback parameter (r) and an ocean flux scaling factor (characterized by the mean carbon flux into the ocean over the 1980s, F (1980s)). Since the model's 1980s-mean net land-use-change flux ( D n (1980s)) is a unique function of r and F (1980s), the model's behaviour can also be characterized by specifying D n (1980s) (instead of r) and F (1980s). The history of past land-use fluxes, D n (t), is derived by inverse modelling for a range of values of F (1980s) (1.0–3.0 GtC/yr) and D n (1980s) (0.6–2.6 GtC/yr). Even with this flexibility, the resultant D n (t) differs markedly from the observationally-based record of Houghton, particularly before 1950. The inverse calculations are used to determine the history of the so-called “missing sink”, as implied directly by the model and by the observationally-based record of D n (t), for a range of ocean uptake efficiencies as defined by F (1980s). Projections of future CO 2 concentration changes are made for the 6 emissions scenarios recently produced by the Intergovernmental Panel on Climate Change (IS92a–f). The ability to specify F (1980s) and D n (1980s) allows one to account for the missing sink in a variety of ways, and to account for uncertainties in the amount of missing carbon. This leads to a range of projections and provides some insights into the uncertainties surrounding these projections. DOI: 10.1034/j.1600-0889.1993. t01-4-00002.x
Effect of Fibers Configuration on Nonlinear Vibration of Anisotropic Dielectric Elastomer Membrane

To describe the specific behavior of soft biological tissues that can be regarded as incompressible, a strain energy function for fiber-reinforcement materials based on two isotropic and anisotropic deformation invariants is developed and investigated. The anisotropic properties of simple composite materials were initially studied and now extensive hyperelastic modeling is used to analyze the dynamic characteristics of a dielectric elastomer membrane that experiences finite strains and is reinforced by one family of fiber. It should be noted that the presence of fibers in the rubber matrix will strengthen the structure, but here the presence of fibers will greatly reduce the electric field required to activate the dielectric elastomer and thus be stimulated with a lower voltage. It even helps to reduce the issue of instability that is a common thing in dielectric elastomers. Therefore, the effect of fiber angle orientation in an anisotropic dielectric elastomer under combined loads of biaxial tensile forces and an electric field with a focus on the damping effects is completely studied for different cases. Based on the Gent model, phase diagrams, dynamic response diagrams, and resonance frequency diagrams are also plotted for several values of fibers directions and damping coefficients.
Phase stability and compression study of (Fe0.89,Ni0.11)3S up to pressure of the Earth’s core

Abstract An in situ synchrotron powder X‑ray diffraction study on (Fe0.89,Ni0.11)3S was conducted up to 141 GPa and 1590 K. (Fe0.89,Ni0.11)3S has a tetragonal structure, which is the same structure as Ni-free Fe3S. Fitting a third-order Birch-Murnaghan equation of state to data at ambient temperature yielded a bulk modulus of K0 = 138.1(7.2) GPa and its pressure derivative K0′ = 4.5(3) with a zero pressure volume V0 = 375.67(4) Å3. The density of (Fe0.89,Ni0.11)3S under the core-mantle boundary condition is 1.7% greater than that of Fe3S. The axial ratio (c/a) of (Fe0.89,Ni0.11)3S decreases with increasing pressure. The addition of nickel to Fe3S leads to a softening of the c-axis. Assuming that the nickel content of the outer core is about 5 at%, we estimated 12.3-20.8 at% sulfur in the outer core for the given 6-10% density deficit between the outer core and pure iron at 136 GPa.
Estimation of Synaptic Activity during Neuronal Oscillations

In the study of brain connectivity, an accessible and convenient way to unveil local functional structures is to infer the time trace of synaptic conductances received by a neuron by using exclusively information about its membrane potential (or voltage). Mathematically speaking, it constitutes a challenging inverse problem: it consists in inferring time-dependent parameters (synaptic conductances) departing from the solutions of a dynamical system that models the neuron’s membrane voltage. Several solutions have been proposed to perform these estimations when the neuron fluctuates mildly within the subthreshold regime, but very few methods exist for the spiking regime as large amplitude oscillations (revealing the activation of complex nonlinear dynamics) hinder the adaptability of subthreshold-based computational strategies (mostly linear). In a previous work, we presented a mathematical proof-of-concept that exploits the analytical knowledge of the period function of the model. Inspired by the relevance of the period function, in this paper we generalize it by providing a computational strategy that can potentially adapt to a variety of models as well as to experimental data. We base our proposal on the frequency versus synaptic conductance curve (f−gsyn), derived from an analytical study of a base model, to infer the actual synaptic conductance from the interspike intervals of the recorded voltage trace. Our results show that, when the conductances do not change abruptly on a time-scale smaller than the mean interspike interval, the time course of the synaptic conductances is well estimated. When no base model can be cast to the data, our strategy can be applied provided that a suitable f−gsyn table can be experimentally constructed. Altogether, this work opens new avenues to unveil local brain connectivity in spiking (nonlinear) regimes.
Who are American evangelical Protestants and why do they matter for US climate policy?

White evangelical Protestants are the most skeptical major religious group in the United States regarding climate change. While their position of political influence in the Republican coalition is widely recognised, the full range of effects of this position on evangelicals' climate opinions is not. To move research on evangelicals from the margins of climate change opinion research, we review and integrate the interdisciplinary literature on US evangelicals, climate change, and politics. In assessing this literature, we identify three areas in need of further research. First, there is a critical need for more research on the climate attitudes of evangelicals of color, who comprise a growing share of the evangelical tradition in the US. Second, highlighting the Christian Right's active engagement in the climate debate, we identify a need for more experimental work examining how cues from religious elites may shape evangelicals' opinions. Finally, we suggest that to better harness insights across disciplines, researchers must become more explicitly aware of how different disciplines conceptualize temporality. Attending to temporal scale suggests that a new approach is needed to test how dominion beliefs, which are widely thought to be an important theological driver of climate skepticism, operate. We also suggest that two factors that appear to play a weak or limited role in driving climate skepticism over the short term (anti‐science attitudes and evangelical religiosity) may in fact play a significant role in driving skepticism over the medium term.
Body Appreciation in Light of Psychological, Health- and Weight-Related Variables Among Female Adolescents

Recent research has begun to focus on positive body image and how this can be supported in adolescence. Body appreciation is a key element of positive body image, and has been associated with self-reported health status, weight-related concern, family factors and psychological variables such as self-esteem. In this study we explored these associations among Hungarian adolescent females. Female high school students from two major towns in Csongrád county, Hungary (N = 454; age range from 14 to 20; M = 16.3 years, SD = 1.2) completed questionnaires assessing body appreciation, self-esteem, optimism, life satisfaction and health- and weight-related variables. Analyses revealed that body appreciation was most strongly related to self-esteem, as well as being positively associated with life satisfaction, self-perceived health, being in control of diet, and engagement in sport. Conversely, binge drinking, engaging in slimming behaviors and having eating disorders in the family were negatively associated with body appreciation. These findings provide some indications of factors that might be targetted in health education programs aiming to promote positive body image and to develop resilience against body dissatisfaction in this demographic group. Such programs should also include information of nutrition and media literacy.
Experimental Research on the Impact of Temperature on the Adhesion Characteristics of Soil-Structure Interface

Under the working condition of mud cake, the continuous action between the shield cutter head and the soil on the excavation surface can generate high temperature in the process of shield tunneling and excavation, which changes the characteristic of the adhesion between the soil and the cutter head to intensify the phenomenon of making a mud cake on cutter, finally leading to a vicious circle. To study the effect of temperature on the characteristics of the adhesion of the soil on the surface of the structure, the soil adhesive situation and adhesion force at different interface temperatures were tested through a self-made experiment device. According to the result, it was indicated that the moisture content has a significant effect on the adhesion force of the soil, and the adhesion force firstly increased and then decreased with the increased of the moisture content and reached the maximum value near the plastic limit moisture content. The adhesion force changes very gently when the interface temperature is low. When the temperature reached 50°C, the adhesion force continues to increase as the interface temperature continuously increases except for the soils with high moisture content; moreover, the interface temperature has a great influence on the content of soil adhered on the structure surface. As for the soil with moderate moisture content ( ω = 21.21 ~ 31 %), this content of the adhered soil increased exponentially with the increase of interface temperature; this content firstly decreased and then increased when the moisture content was high. When the soil was dry, there was almost no adhered soil on the surface and the interface temperature had no effect on the adhesive situation. By comparing and analyzing the adhesion state of the soil on the surface of the structure, the influence of temperature on the adhesion characteristics is mainly reflected on the variation of the soil moisture content within the influence range of the interface, the variation of the energy required for the destruction of the adhesion interface, and the change of the location of the weakest antistripping plane induced by both before. This research can better understand the law of formation and development of mud cakes and provided a new idea of solving the problem of mud cakes on the cutter head.
A NOVEL COMPACT WEARABLE ANTENNA DESIGN FOR ISM BAND

A compact wearable antenna operating at 2.45 GHz with a novel Electromagnetic Band Gap (EBG) structure as a reflector is proposed. The broadband monopole is used as the main radiator of the antenna, and the gradient feeder structure and etched slot on the ground are used to adjust the matching effect of the antenna port. The current path is extended, and the structure is made more compact by slotting the surface of the EBG cell. Then, a 3 × 3 EBG reflector is constructed and loaded to the bottom of the antenna to improve the antenna gain performance and reduces the specific absorptivity (SAR). A three-layer human model (skin-fat-muscle) has been built in High Frequency Structure Simulator (HFSS) to analyse the influence of human tissue on the wearable antenna system. Combined with the practical application background, the radiation performance of the system under bending is also explored. The simulation results show that the application of EBG reflector can increase the antenna gain by about 4.77 dBi and the front-to-back ratio by 17 dB, reduce SAR by more than 95%, and the overall size of the system is only 60.3 × 60.3 × 3.5 mm3 (0.49λ). The antenna system has the characteristics of simple structure, small size, high gain, and low SAR value, which is of certain reference value for the research on the wearable antenna.
The New Matrix Model of Computation Based Purely on Quite a New Concept of the Matrix Computations for Extremely Quick Web Pages Loading

We all dream of quick loading. Quicker than it is now. So that it loads immediately. What is needed for this? There are a lot of things to do. The most important things in it are computations. To speed up loading, we need to speed up computations. If we will find the way to multiply large numbers quicker than we have, the loading will be much quicker. How to do that? We need to multiply large numbers in time O(log n). How is that possible? A new model of computation may solve this problem. These are the algorithms that require considerably less amount of resources to perform them. The time complexity of the algorithm is the main (key) resource that we need to reduce to get the desired complexity. It seems incredible, but it is possible. We will get this through the sorting array. Best, worst, and average cases of a given algorithm could be considered for each particular input instance of the problem when analyzing algorithms. The worst-case complexity is the most used in algorithm analysis, it gives an upper bound on the resources required by the algorithm. Thus, the discovery of better algorithms brings the upper bound on the worst-case running time down. This paper presents the new matrix model of computation, which is based on the concept of the new matrix computations for advanced computing. The paper intends to prove the existence of better algorithms for any given input instance of the worst-case time complexity M(n) = O(n2) that take O(log n) and provide extremely quick web pages loading and create a new topic in complexity.
Establishing the South Australian Macrobenthic Traits (SAMT) database: A trait classification for functional assessments

Abstract Trait‐based approaches are increasingly used as a proxy for understanding the relationship between biodiversity and ecosystem functioning. Macrobenthic fauna are considered one of the major providers of ecosystem functions in marine soft sediments; however, several gaps persist in the knowledge of their trait classification, limiting the potential use of functional assessments. While trait databases are available for the well‐studied North Atlantic benthic fauna, no such trait classification system exists for Australia. Here, we present the South Australian Macrobenthic Traits (SAMT) database, the first comprehensive assessment of macrobenthic fauna traits in temperate Australian waters. The SAMT database includes 13 traits and 54 trait‐modalities (e.g., life history, morphology, physiology, and behavior), and is based on records of macrobenthic fauna from South Australia. We provide trait information for more than 250 macrobenthic taxa, including outcomes from a fuzzy coding procedure, as well as an R package for using and analyzing the SAMT database. The establishment of the SAMT constitutes the foundation for a comprehensive macrobenthic trait database for the wider southern Australian region that could facilitate future research on functional perspectives, such as assessments of functional diversity and changes to ecosystem functioning.
