Published: August 2024

Kegagalan dalam masa panen tentunya bukan hal yang diinginkan oleh para pembudidaya, salah satu faktor yang menyebabkan gagal panen ialah kekurangan air. Maka dibuatlah alat penyiram tanaman otomatis berbasis ESP8266 agar tanaman mendapatkan perhatian khusus, salah satunya yaitu mendapat asupan air yang cukup. Alat penyiram tanaman otomatis berbasis ESP8266 ini dibuat dengan metode prototype dan diuji dengan metode BlackBox menggunakan sensor kelembaban tanah dan sensor suhu, sensor kelembaban tanah dapat membaca kelembaban dengan nilai antara 0-1024 dan sensor suhu dapat membaca 0-100℃. Dimana semakin tinggai nilainya maka kondisi tanah akan semakin kering begitupun sebaliknya. Kelembaban tanah yang baik untuk tanaman bayam ialah sekitar 409-614 dan suhu udara kurang dari 28℃. Maka dapat diambil angka 512-614 dengan nilai maksimal 409, dimana jika angka yang ditampilkan lebih dari 614 pompa air akan menyala dan berhenti jika angka yang ditampilkan kurang dari 512 dengan tambahan tombol ON/OFF untuk mematikan atau menyalakan pompa air pada saat suhu udara terlalu panas (suhu udara diatas 28℃) sehingga tanaman bayam bisa mendapatkan nilai kelembaban tanah maksimal yaitu 409. Hasil dari pengujian alat dan aplikasi ini ialah sensor dapat membaca nilai kelembaban tanah yaitu nilai minimal 387 dan nilai maksimal 724, sedangkan suhu udara minimal 25℃ dan suhu udara maksimal 32℃.

Ktahkomiq: Language as a Territory
Authors: Burelle Julie 
Published: August 2024

This article discusses the performance Ktahkomiq (“Territory”) created in 2017 by Dave Jenniss and Ivanie Aubin-Malo with the dramaturgical support of Catherine Joncas. I examine the creative process developed by the artists to explore a long-standing conflict dividing their community without minimizing its irreconcilable dimensions. In particular, I attend to the moments of refusal and reconciliation that shape the performance as well as the role that the Wolastoqey language played in creating a shared territory for the artists.

Published: August 2024

The paper evaluates the prevalence of psychoactive substance use in a non-clinical sample of university students and examines its relation to childhood traumatic experiences and common mental health problems. An anonymous online survey was conducted between September 2022 and May 2023 in two major universities in Bulgaria using opportunity sampling. The study has a cross-sectional, observational, and retrospective design, using self-rating scales for depression, anxiety, alexithymia, empathy, quality of life, and lifetime history of substance use. One hundred and forty-six university students completed the survey, with a mean age of 23 years (SD=2), 66% females. Ninety-eight percent of the participants have used caffeine, 90% alcohol, 62% tobacco, 50% cannabis, 26% sedatives, 19% amphetamines, 12% inhalants, 8% hallucinogens, 4% opiates, and 9% other/unknown substances. The mean number of psychoactive substances used within a lifetime is 4 (SD=2). Forty-two (29%) participants have a history of use of multiple (≥ 5) types of psychoactive substances. Statistically significant differences from the rest of the sample include lower empathy (p=.016), higher scores on the childhood trauma scale (p=.001), and a higher percentage of dissociative symptoms (47.6%, p=.012). The binary logistic regression model revealed that higher scores on the childhood trauma scale (p=.003) and lower empathy (p=.004) are statistically significant predictors of multiple substance use. In conclusion, the lifetime use of multiple psychoactive substances in non-clinical settings is related to underlying childhood traumatic experiences and lower empathy.

Background
Next-generation sequencing of Mycobacterium tuberculosis, the infectious agent causing tuberculosis, is improving the understanding of genomic diversity of circulating lineages and strain-types, and informing knowledge of drug resistance mutations. An increasingly popular approach to characterizing M. tuberculosis genomes (size: 4.4 Mbp) and variants (e.g., single nucleotide polymorphisms (SNPs)) involves the de novo assembly of sequence data.

Methods
We compared the performance of genome assembly tools (Unicycler, RagOut, and RagTag) on sequence data from nine drug resistant M. tuberculosis isolates (multi-drug (MDR) n = 1; pre-extensively-drug (pre-XDR) n = 8) generated using Illumina HiSeq, Oxford Nanopore Technology (ONT) PromethION, and PacBio platforms.

Results
Our investigation found that Unicycler-based assemblies had significantly higher genome completeness (~98.7%; p values = 0.01) compared to other assembler tools (RagOut = 98.6%, and RagTag = 98.6%). The genome assembly sizes (bp) across isolates and sequencers based on RagOut was significantly longer (p values < 0.001) (4,418,574 ± 8,824 bp) than Unicycler and RagTag assemblies (Unicycler = 4,377,642 ± 55,257 bp, and RagTag = 4,380,711 ± 51,164 bp). RagOut-based assemblies had the fewest contigs (~32) and the longest genome size (4,418,574 bp; vs. H37Rv reference size 4,411,532 bp) and therefore were chosen for downstream analysis. Pan-genome analysis of Illumina and PacBio hybrid assemblies revealed the greatest number of detected genes (4,639 genes; H37Rv reference contains 3,976 genes), while Illumina and ONT hybrid assemblies produced the highest number of SNPs. The number of genes from hybrid assemblies with ONT and PacBio long-reads (mean: 4,620 genes) was greater than short-read assembly alone (4,478 genes). All nine RagOut hybrid genome assemblies detected known mutations in genes associated with MDR-TB and pre-XDR-TB.

Conclusions
Unicycler software performed the best in terms of achieving contiguous genomes, whereas RagOut improved the quality of Unicycler’s genome assemblies by providing a longer genome size. Overall, our approach has demonstrated that short-read and long-read hybrid assembly can provide a more complete genome assembly than short-read assembly alone by detecting pan-genomes and more genes, including IS6110, and SNPs.
Temporal observations of a linear sand dune in the Simpson Desert, central Australia: Testing models for dune formation on planetary surfaces

Published: October 2015

AbstractLinear dunes are the most common dune form found on planetary surfaces, yet questions remain about their formation. Temporal observations of a linear dune located in the Simpson Desert of central Australia were made to monitor dune movement and to test competing hypotheses regarding linear dune formation. Our observations were collected on three separate occasions from 2006 to 2014. Rebar stakes were placed in a gridded pattern so that multiple measurements of sand thickness, GPS surveys, and photographs could be taken at the same locations over time. We observed widespread reworking of sand on and around the dune crest, with sand accumulation locally exceeding a meter between surveys. Overall, the height of the dune crest increased by several centimeters. We also observed fluctuations in the sand cover in the adjacent swales that often exceeded 2–3 cm between surveys, yet we did not observe any appreciable changes in the position of the dune's downwind terminus. Weather data indicate that the effective sand‐transporting winds in the Simpson are widely unimodal. Net sediment flux (resultant drift direction) is toward the north‐northwest, locally at an oblique angle to dune orientation. Collectively, our results suggest that the linear dune is actively maintained by vertical accretion. The implications from our observations are that linear dunes on other planetary surfaces could form in wind regimes that are widely unimodal, even where the resultant drift direction is locally oblique to dune orientation. In particular, such findings may provide support for global circulation models of Titan.
Synthesis and application of a real‐time model‐free behavioral controller with bumpless switching mechanism
Authors: Jain Tushar , Yamé Joseph J. 
Published: October 2015

SummaryThe aims of this paper are twofold. Firstly, we present a model‐free algorithm for synthesizing an online controller. Secondly, this algorithm also addresses the issue of switching this controller in a closed loop with a bumpless interconnection mechanism. The novelty of this algorithm lies in the fact that we do not use any a priori knowledge of the model of the plant in real time. We use the mathematical framework of behavioral system theory to demonstrate the online controller synthesis and its implementation mechanism. The effectiveness of the proposed algorithm is demonstrated on the experimental three‐tank system. Copyright © 2015 John Wiley & Sons, Ltd.

Published: October 2015

AbstractA crystallographically characterized three‐coordinate, formally 14 electron PtII complex 1 featuring terminal amido ligation is reported. Computational analysis revealed relatively weak π donation from the amide lone pair to platinum and supports a 14‐electron assignment for 1. Stoichiometric reactivity studies confirmed the viability of net OH and CH addition across, as well as isonitrile insertion into, the terminal platinum–amido linkage of 1.

Authors: Nairoukh Zackaria , Marek Ilan 
Published: October 2015

AbstractThe regio‐ and stereoselective formation of stereodefined polysubstituted silyl ketene aminals is easily achieved through selective combined carbometalation–oxidation–silylation reactions. These substrates are ideal candidates for Mukaiyama aldol reactions with aliphatic aldehydes as they give the aldol products with a quaternary carbon stereocenter α to the carbonyl groups in outstanding diastereoselectivities.

Published: October 2015

AbstractSilica aerogels are excellent thermal insulators, but their brittle nature has prevented widespread application. To overcome these mechanical limitations, silica–biopolymer hybrids are a promising alternative. A one‐pot process to monolithic, superinsulating pectin–silica hybrid aerogels is presented. Their structural and physical properties can be tuned by adjusting the gelation pH and pectin concentration. Hybrid aerogels made at pH 1.5 exhibit minimal dust release and vastly improved mechanical properties while remaining excellent thermal insulators. The change in the mechanical properties is directly linked to the observed “neck‐free” nanoscale network structure with thicker struts. Such a design is superior to “neck‐limited”, classical inorganic aerogels. This new class of materials opens up new perspectives for novel silica–biopolymer nanocomposite aerogels.
Controlled Handedness of Twisted Lamellae in Banded Spherulites of Isotactic Poly(2‐vinylpyridine) as Induced by Chiral Dopants

Published: October 2015

AbstractHerein, we suggest a unique approach to control the handedness of twisted lamellae in banded spherulites of a stereoregular polymer, isotactic poly(2‐vinylpyridine) (iP2VP). When (R)‐ or (S)‐hexahydromandelic acid (HMA), which can associate with iP2VP, was introduced as a chiral dopant, mirror‐image CD spectra in the complex systems showed induced circular dichroism (ICD) of the iP2VP by chiral HMA. Banded spherulites resulting from lamellar twisting due to the imbalanced stresses at the opposite folding surfaces could be formed by crystallization of the iP2VP/HMA complexes, which had a crystalline structure similar to that of neat iP2VP. A preferential sense of the twisted crystalline lamellae was found in the iP2VP/HMA complex, thus suggesting homochiral evolution from conformational to hierarchical chirality.

Published: October 2015

AbstractDiffusion in nanoporous host–guest systems is often considered to be too complicated to comply with such “simple” relationships as Fick’s first and second law of diffusion. However, it is shown herein that the microscopic techniques of diffusion measurement, notably the pulsed field gradient (PFG) technique of NMR spectroscopy and microimaging by interference microscopy (IFM) and IR microscopy (IRM), provide direct experimental evidence of the applicability of Fick’s laws to such systems. This remains true in many situations, even when the detailed mechanism is complex. The limitations of the diffusion model are also discussed with reference to the extensive literature on this subject.
Highly Charged Ruthenium(II) Polypyridyl Complexes as Lysosome‐Localized Photosensitizers for Two‐Photon Photodynamic Therapy
Authors: Huang Huaiyi , Yu Bole , Zhang Pingyu , Huang Juanjuan , Chen Yu , Gasser Gilles , Ji Liangnian , Chao Hui 
Published: October 2015

AbstractPhotodynamic therapy (PDT) is a noninvasive medical technique that has received increasing attention over the last years and been applied for the treatment of certain types of cancer. However, the currently clinically used PDT agents have several limitations, such as low water solubility, poor photostability, and limited selectivity towards cancer cells, aside from having very low two‐photon cross‐sections around 800 nm, which limits their potential use in TP‐PDT. To tackle these drawbacks, three highly positively charged ruthenium(II) polypyridyl complexes were synthesized. These complexes selectively localize in the lysosomes, an ideal localization for PDT purposes. One of these complexes showed an impressive phototoxicity index upon irradiation at 800 nm in 3D HeLa multicellular tumor spheroids and thus holds great promise for applications in two‐photon photodynamic therapy.
Synthesis and properties of gradient copolymers of butyl methacrylate and fluorinated acrylate via RAFT miniemulsion copolymerizations
Authors: Zhang Guangfa , Zhang Qinghua , Wang Qiongyan , Zhan Xiaoli , Chen Fengqiu 
Published: October 2015

ABSTRACTA series of gradient fluorinated copolymers with a broad variation of the monomer units in the polymer chain were synthesized via semibatch CPDB‐mediated RAFT miniemulsion polymerization technique. In the presence of RAFT agent 2‐cyanoprop‐2‐yl dithiobenzoate (CPDB), the copolymerization of BMA and FMA in miniemulsion exhibited typical features of a controlled molecular weights and narrow polydispersities. The macromolecular structure and thermal behavior of the synthesized fluorinated copolymers were investigated in detail. The DSC analyses show that the gradient copolymers showed a unique thermal behavior with broad range of transition temperature. It was also confirmed that the fluorinated gradient copolymer exhibited obvious surface segregation structure and ultra‐low surface energy between 16.8 and 20.3 mN/m. © 2015 Wiley Periodicals, Inc.

Published: October 2015

ABSTRACTA simple and environmental friendly oxoacetohydrazide functionalization method is developed to convert the straw cellulose into high performance adsorbents for effective Pb(II) removal. The adsorption experimental results demonstrated that the resultant oxoacetohydrazide‐modified cellulose (OMC) possesses a dramatically improved Pb(II) adsorption capacity (82.9 mg/g), which is over six times of that for the unmodified celluloses (13.6 mg/g). The mechanistic studies confirm that the markedly enhanced Pb(II) adsorption capability of OMC can be attributed to the formation of N‐Pb‐N bonds resulting from the strong chelating interactions of Pb(II) with oxoacetohydrazide. Also, the OMC shows an excellent reusability, capable of retain 95% of its original Pb(II) adsorption capacity after three consecutive adsorption cycles. The findings of this work pave a way to transform the agricultural byproducts into high performance functional materials. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 42950.
