Handphone (HP) bagi siswa dapat dimanfaatkan sebagai media pembelajaran. Namun, penggunaan HP yang salah juga menyebabkan dampak negatif. Siswa di kota Yogyakarta yang dikenal memiliki kualitas pendidikan baik, juga rentan mengalami dampak negatif. Hal ini terutama bagi siswa SMP yang berada pada usia remaja awal. Terlebih adanya pandemi COVID-19 menyebabkan frekuensi penggunaan HP pada siswa meningkat karena adanya pembelajaran daring. Saat ini tiap sekolah memiliki kebijakan yang berbeda berkaitan dengan penggunaan HP oleh siswa di sekolah. Belum adanya forum yang mempertemukan perwakilan dari SMP di kota Yogyakarta menyebabkan belum diketahui secara detail berkaitan aturan tersebut. Untuk itu penelitian ini bertujuan untuk mengetahui gambaran aturan penggunaan HP saat ini dan memberikan usulan kebijakan berkaitan pemanfaatan teknologi dan penggunaan HP di sekolah oleh siswa SMP di kota Yogyakarta. Metode yang digunakan dalam penelitian ini yaitu kombinasi kuantitatif-kualitatif, dengan menggunakan analisis deskriptif dan transkrip dan koding. Sampel yang digunakan yaitu 14 SMP di kota Yogyakarta yang mewakili setiap cluster sekolah. Analisis deskriptif dilakukan berdasarkan hasil kuesioner yang dibagikan kepada responden siswa, sedangkan teknik transkrip dan koding digunakan berdasarkan hasil wawancara dengan kepala sekolah, guru, siswa, orangtua siswa, dan UPT Layanan Disabilitas (ULD). Hasil wawancara menjadi acuan untuk rumusan kebijakan berkaitan aturan penggunaan HP untuk siswa SMP. Focus Group Discussion (FGD) dengan kepala sekolah dan ULD juga dilakukan untuk mengkonfirmasi hasil sementara peelitian dan menerima masukan. Hasil menunjukkan, SMP di kota Yogyakarta saat ini memiliki 2 jenis aturan yang diterapkan. Aturan tersebut yaitu: 1) siswa dilarang membawa HP ke sekolah; 2) siswa dibolehkan membawa HP ke sekolah tetapi harus dikumpulkan di loker kelas ataupun dititipkan untuk disimpan guru atau TU. Namun, kedua aturan tersebut mengizinkan siswa membawa HP ke kelas apabila guru meminta penggunaan HP sebagai media pembelajaran. Akibatnya terjadi penyalahgunaan HP untuk keperluan di luar pembelajaran. Untuk itu rancangan usulan kebijakan yang dibuat bagi sekolah terdiri dari 3 hal, yaitu: 1). Sosialisasi pada guru, siswa, dan orangtua siswa tentang pentingnya mendampingi siswa dalam penggunaan HP dan aturan sekolah tentang penggunaan HP; 2) Aturan penggunaan HP bagi siswa SMP di sekolah, yaitu siswa dibolehkan membawa HP ke sekolah tetapi harus dikumpulkan di loker kelas ataupun dititipkan untuk disimpan guru atau TU dalam keadaan mati dan dapat diambil kembali setelah jam pelajaran pada hari tersebut selesai; 3) HP tidak boleh digunakan sebagai media pembelajaran di dalam kelas. Namun, HP dapat dimanfaatkan sebagai media pembelajaran di luar sekolah.

Inventaire de papillons de jour (Papilionoidea) au bois de Brossard : portrait et tendances
Authors: Drapeau Picard André-Philippe 
Published: September 2024

Dans les paysages anthropisés, les milieux naturels constituent des refuges pour la biodiversité. Le bois de Brossard fait partie de l’un des derniers grands habitats forestiers en Montérégie, au Québec. Cet article vise à brosser un portrait de la communauté de papillons de jour de ce site, puis à évaluer la contribution des milieux fermés et ouverts à la biodiversité du site. Les papillons de jour (Lepidoptera : Papilionoidea) du bois de Brossard ont été inventoriés de 2018 à 2022. Trente-six espèces ont été répertoriées. Le nombre d’espèces était comparable dans les 2 types de milieux, mais les courbes d’accumulation d’espèces et les indices de biodiversité laissent penser que le milieu ouvert est plus diversifié. De plus, 65 % des espèces étaient communes aux 2 types de milieux. Les données présentées dans cet article fourniront une base de référence pour documenter les changements futurs dans la composition des communautés des 2 types de milieux.
Toward “all weather,” long record, and real‐time land surface temperature retrievals from microwave satellite observations
Authors: Prigent C. , Jimenez C. , Aires F. 
Published: May 2016

AbstractThe land surface temperature can be estimated from satellite passive microwave observations, with limited contamination from the clouds as compared to the infrared satellite retrievals. With ∼60% cloud cover in average over the globe, there is a need for “all weather,” long record, and real‐time estimates of land surface temperature (Ts) from microwaves. A simple yet accurate methodology is developed to derive the land surface temperature from microwave conical scanner observations, with the help of precalculated land surface microwave emissivities. Different tests are conducted to optimize the algorithms. The method is applied to the Special Sensor Microwave/Imagers (SSM/I) observations over 2 years, regardless of the cloud cover. The results are compared to infrared estimates from International Satellite Cloud Climatology Project (ISCCP) and from Advanced Along Track Scanning Radiometer (AATSR), under clear‐sky conditions. Limited biases are observed (∼0.5 K for both comparisons) with a root‐mean‐square error (RMSE) of ∼5 K, to be compared to the RMSE of ∼3.5 K between ISCCP et AATSR. Cloud contamination in the AATSR estimates have been evidenced, and a simple filtering has been proposed. The microwave surface temperatures have also been carefully compared to in situ Ts time series from a collection of more than 20 stations over a large range of environments. Very good agreement is obtained for well‐controlled stations in vegetated environments (down to RMSE of ∼2.5 K for several stations), but the methodology encounter difficulties under cold conditions due to the large variability of snow and ice surface emissivities.

Published: May 2016

AbstractExploration of biodegradable and renewable composites ingredients is of great importance. Up to now, roots extract of Glycyrrhiza glabra has been used for different medicinal purposes but remaining cellulose‐rich residues have not been evaluated for isolation of any green materials like cellulose. Here in this study, cellulose was successfully isolated from the roots of G. glabra by using conventional cellulose extraction method. The obtained product was characterized using FT‐IR, XRD, and SEM. FT‐IR and XRD analyses confirmed the identity of the product. The crystallinity index of cellulose isolates was calculated from XRD data as 70%. The cellulose content of the roots on dry basis was recorded as 48.5%. Three types of surface morphologies were observed: smooth non‐porous surface, surface with fibril bundles, and porous surface having thin cellulose fibrils. In addition, bovine serum albumin (BSA) adsorption capacity of G. glabra cellulose was determined and compared with that of commercial cellulose. Newly obtained cellulose from the roots of G. glabra exhibited a higher affinity for BSA protein at neutral pH.

Water Oxidation by Ruthenium Complexes Incorporating Multifunctional Bipyridyl Diphosphonate Ligands
Authors: Xie Yan , Shaffer David W. , Lewandowska‐Andralojc Anna , Szalda David J. , Concepcion Javier J. 
Published: May 2016

AbstractWe describe herein the synthesis and characterization of ruthenium complexes with multifunctional bipyridyl diphosphonate ligands as well as initial water oxidation studies. In these complexes, the phosphonate groups provide redox‐potential leveling through charge compensation and σ donation to allow facile access to high oxidation states. These complexes display unique pH‐dependent electrochemistry associated with deprotonation of the phosphonic acid groups. The position of these groups allows them to shuttle protons in and out of the catalytic site and reduce activation barriers. A mechanism for water oxidation by these catalysts is proposed on the basis of experimental results and DFT calculations. The unprecedented attack of water at a neutral six‐coordinate [RuIV] center to yield an anionic seven‐coordinate [RuIV−OH]− intermediate is one of the key steps of a single‐site mechanism in which all species are anionic or neutral. These complexes are among the fastest single‐site catalysts reported to date.
ABS/HIPS blends obtained from WEEE: Influence of processing conditions and composition

Published: May 2016

ABSTRACTThe recycling of acrylonitrile–butadiene–styrene (ABS) and high‐impact polystyrene (HIPS) from postconsumer electronic equipment housing was investigated. A preliminary study of shot size and particle size effects on the mechanical properties of ABS/HIPS (50/50) blends obtained directly via injection molding was conducted. Injection‐molded specimens of ABS/HIPS blends, obtained at different compositions with or without previous extrusion, were subjected to mechanical, thermal, and morphological testing. Preliminary studies showed that a smaller particle size resulted in higher tensile and impact strength, regardless of the shot size used during injection molding. ABS/HIPS blends obtained using previous extrusion presented a slight increase in Young's modulus and a decrease in elongation at break and impact strength. The increase in glass‐transition temperature related to the Polybutadiene (PB) phases of these blends indicated a possible increase in crosslinking structures during extrusion. In addition, these blends showed a coarse and heterogeneous morphology, suggesting that ABS did not completely mix with HIPS. Compared to processing conditions, the blend composition appeared to have a much stronger effect on the mechanical properties. The results obtained suggest the possibility of obtaining ABS/HIPS blends directly via injection molding as long as small ground particles are used. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Published: May 2016

ABSTRACTPhotochemically mediated controlled/“living” polymerization of methyl methacrylate (MMA) triggered by flavone was studied. The polymerization was performed in ethanol at ambient temperature with CuBr2/Tris(2‐dimethylaminoethyl)amine (Me6TREN) as complex catalyst and ethyl 2‐bromoisobutyrate (EBiB) as initiator. The molar mass of poly(methyl methacrylate) (PMMA) was obtained and exhibited relatively narrow molecular weight distribution (Mw/Mn) which was characterized by gel permeation chromatography (GPC). Chain extension further indicated that the living nature was maintained in the photopolymerization system. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43845.

Published: May 2016

BackgroundAfter years of periconceptional folic acid supplementation, the prevalence of neural tube defects (NTDs) remains stable following the remarkable reduction observed immediately after the fortification practice. There is accumulating evidence that folate receptor (FR) autoimmunity may play a role in the etiology of folate‐sensitive NTDs.MethodsFrom 2011 to 2013, 118 NTD cases and 242 healthy controls were recruited from a population‐based birth defects surveillance system in Northern China. Enzyme‐linked immunosorbent assay was used to measure FR autoantibodies in maternal and cord blood. Logistic regression models were used to estimate the odds ratios (OR) and 95% confidence intervals (95% CI).ResultsPlasma FR autoantibodies levels were significantly elevated in mothers of infants with NTDs compared with mothers of healthy controls. Using the lowest tertile as the referent group, 2.20‐fold (95% CI, 0.71–6.80) and 5.53‐fold increased odds (95% CI, 1.90–16.08) of NTDs were observed for the second and third tertile of immunoglobulin G (IgG), respectively, and the odds of NTDs for each successive tertile of IgM was 0.98 (95% CI, 0.35–2.75) and 3.49 (95% CI, 1.45–8.39), respectively. A dose–response relationship was found between FR autoantibodies levels and risk of NTDs (P< 0.001 for IgG,P= 0.002 for IgM). The same pattern was observed in both subtypes of spina bifida and anencephaly. No significant difference in levels of cord blood FR autoantibodies was observed.ConclusionHigher levels of FR autoimmunity in maternal plasma are associated with elevated risk of NTDs in a dose–response manner.

Quantification of total phosphorothioate in bacterial DNA by a bromoimane‐based fluorescent method
Authors: Xiao Lu , Xiang Yu 
Published: May 2016

AbstractThe discovery of phosphorothioate (PT) modifications in bacterial DNA has challenged our understanding of conserved phosphodiester backbone structure of cellular DNA. This exclusive DNA modification in bacteria is not found in animal cells yet, and its biological function in bacteria is still poorly understood. Quantitative information about the bacterial PT modifications is thus important for the investigation of their possible biological functions. In this study, we have developed a simple fluorescence method for selective quantification of total PTs in bacterial DNA, based on fluorescent labeling of PTs and subsequent release of the labeled fluorophores for absolute quantification. The method was highly selective to PTs and not interfered by the presence of reactive small molecules or proteins. The quantification of PTs in an E. coli DNA sample was successfully achieved using our method and gave a result of about 455 PTs per million DNA nucleotides, while almost no detectable PTs were found in a mammalian calf thymus DNA. With this new method, the content of phosphorothioate in bacterial DNA could be successfully quantified, serving as a simple method suitable for routine use in biological phosphorothioate related studies.

Published: May 2016

AbstractPostharvest herbal product contamination with mycotoxins and mycotoxin‐producing fungi represents a potentially carcinogenic hazard. Aspergillus flavus is a major cause of this issue. Available mold detection methods are PCR‐based and rely heavily on laboratories; thus, they are unsuitable for on‐site monitoring. In this study, a bendable, paper‐based lab‐on‐a‐chip platform was developed to rapidly detect toxigenic Aspergillus spp. DNA. The 3.0‐4.0 cm2 chip is fabricated using Whatman™ filter paper, fishing line and a simple plastic lamination process and has nucleic acid amplification and signal detection components. The Aspergillus assay specifically amplifies the aflatoxin biosynthesis gene, aflR, using loop‐mediated isothermal amplification (LAMP); hybridization between target DNA and probes on blue silvernanoplates (AgNPls) yields colorimetric results. Positive results are indicated by the detection pad appearing blue due to dispersed blue AgNPls; negative results are indicated by the detection pad appearing colorless or pale yellow due to probe/target DNA hybridization and AgNPls aggregation. Assay completion requires less than 40 min, has a limit of detection (LOD) of 100 aflR copies, and has high specificity (94.47%)and sensitivity (100%). Contamination was identified in 14 of 32 herbal samples tested (43.75%). This work demonstrates the fabrication of a simple, low‐cost, paper‐based lab‐on‐a‐chip platform suitable for rapid‐detection applications.
