Rancang Bangun Prototipe Sistem Monitoring Suhu serta Penyemprot Hand Sanitizer Otomatis Berbasis Internet of Things
Authors: Hidayanto Mochammad Wahyu , Noni Juliasari  
Published: August 2024

Tempat pelayanan publik merupakan tempat dimana aktivitas manusia banyak terjadi sehingga sering terjadi kontak antar manusia, baik kontak langsung maupun kontak tidak langsung. Kontak langsung dapat terjadi ketika berjabat tangan dan kontak tidak langsung terjadi ketika menggunakan benda atau fasilitas umum secara bergantian. Kontak langsung atau tidak langsung menjadi sarana yang efektif untuk penyebaran virus atau bakteri sehingga hal ini menjadikan tempat pelayanan publik menjadi area yang kondusif bagi penyebaran virus atau bakteri. Oleh karena itu diperlukan cara untuk mencegah menyebarnya virus atau bakteri pada tempat pelayanan publik yaitu minimal tersedianya tempat pencuci tangan yang mudah dijangkau dan mudah digunakan. Maka dirancanglah sebuah sistem Monitoring Suhu Serta Penyemprot Hand Sanitizer Otomatis berbasis IoT. Alat ini menggunakan mikrokontroller nodeMCU sebagai alat pengendali untuk menggerakan sistem secara keseluruhan. Pada alat ini menggunakan sensor suhu MLX9014 untuk mengukur suhu dari pengguna, sensor ultrasonic hc-sr04 untuk mendeteksi keberadaan tangan dari pengguna, motor servo untuk menggerakkan tuas dari botol handsanitizer, sensor IR-Obstacle untuk memonitoring isi dari handsanitizer. Semua data sensor yang masuk ke NodeMCU akan dikirim ke database mysql dan ditampilkan di aplikasi berbasis web. Penyemprotran hand sanitizer dilakukan pada saat ada pengguna mendekatkan tangan ke sensor suhu dan terdeteksi oleh sensor ultrasonik. Pada saat suhu pengguna diatas 370C maka buzzer akan berbunyi sebagai alarm dan pada saat isi handsanitizer akan habis akan terkirim notitikasi ke web server dan ditampilkan di halaman web. Monitoring suhu dan isi handsanitizer dapat dilihat melalui aplikasi web.

« Nous pouvons parler pour nous-mêmes » : un atelier de théâtre appliqué sur la décolonisation, à l’intention des juges
Authors: Jerke Lauren , Arcand Rupert , Ward Rocky 
Published: August 2024

Cet article explique comment nous avons développé et animé un atelier de théâtre appliqué d’une journée sur la décolonisation, pour des juges. L’atelier a d’abord fourni aux juges un cadre pour prendre en compte l’histoire coloniale du Canada et les idées coloniales actuelles qui se manifestent en nous. Ensuite, l’atelier a donné aux juges l’occasion de sortir de leur rôle professionnel habituel et d’examiner comment les besoins des jeunes autochtones sont abordés au tribunal du point de vue d’une jeune personne et de sa grand-mère. L’objectif de notre atelier était de réfléchir collectivement à ce que signifie notre propre décolonisation et celle de notre système judiciaire. Cette étude de cas démontre que les « règles d’engagement » sont flexibles, mais qu’elles doivent être soutenues par les connaissances culturelles, le respect des protocoles culturels, la réflexion, le respect de l’expérience vécue et l’ouverture à l’apprentissage pour toustes.
Risk Factors for Very Long ICU Stay after Cardiac Surgery and Effects on the Quality of Life
Authors: Abedinov Fillip 
Published: August 2024

Risk factors for long stay in Intensive Care Unit (ICU) and the effect on the quality of life following cardiac surgery are of interest as the recourses for patient recuperation increase. The aim of the study was to assess risk factors inducing very long stay in a ICU after cardiac surgery and the quality of life a year later and more. This is a three years prospective and retrospective study at a university hospital ICU with 17 beds. Eighty out of 3619 patients undergoing cardiac surgery under extracorporal circulation and necessitating more than nine days ICU, are included in the study group. Patients with ICU stay more than 14 days out of same group - very long stay - are subject to additional risk factors study. Eighty-three of the operated patients with up to three days ICU stay represent the control group. Generic NHP questionnaire is used [1]. Multifactorial analysis determines as risk factor dopamine infusion >13 days (P<0.001) (ODD=167.5). Patients who experienced sepsis have affected physical ability (P=0.014), those with low cardiac output syndrome, social isolation (P=0.023) and affected physical ability (P=0.011) and emotional reaction (P=0.001) Very long stay in ICU following cardiac surgery is caused by persistent heart failure complicated by respiratory and renal one, as well as need of massive blood transfusion. Patients with long ICU stay and surviving sepsis and/or LCOS experience long term effects on the quality of life.

Published: August 2024

The goals of the study were to assess the diversity and structure of the bacterial communities within the soil depth along a gradient of heavy metal (HM) contamination and to identify indigenous bacterial species in the agricultural area of a non-ferrous metal plant KCM 2000 Group (Plovdiv) by using 16S rRNA gene retrieval. 16S rRNA gene clone libraries were constructed for nine samples, which were collected from two soil depths in June 2020. From each library, up to 100 clones were analysed and grouped into operational taxonomic units (OTUs) by restriction fragment length polymorphism (RFLP). The representatives of the OTUs were sequenced, followed by phylogenetic analysis. The results revealed that phyla Proteobacteria (11.11–71.43%) and Actinomycetota (3.57–33%) were the most abundant. Surface soils (12 phyla and 15 classes) were more diverse than subsurface ones (7 phyla and 12 classes). The lowest diversity at both phylum and class levels was calculated for the moderately contaminated soils from the two studied depths. Thirteen 16S rDNA sequences were identified to a species level, and they belonged to Proteobacteria, Actinomycetota and Firmicutes. This study highlighted that both HM contamination and soil depth caused shifts in diversity and structure of soil bacterial communities.
Intraplate volcanism of the western Pacific: New insights from geological and geophysical observations in the Pigafetta Basin
Authors: Stadler Timothy J. , Tominaga Masako 
Published: September 2015

AbstractUnderstanding intraplate volcanism is a key to deciphering the Earth's magmatic history. One of the largest intraplate volcanic events occurred during the mid‐Cretaceous, roughly 75–125 Ma in the western Pacific. To investigate the origin of this volcanism we present the first comprehensive study of volcanism in the Pigafetta Basin using seismic surveys, magnetic and gravity modeling, and Ocean Drilling Program (ODP) drill core and well log data from Site 801. Our results show that intraplate volcanism in the Pigafetta Basin coincides with the rest of the western Pacific seamount provinces, supporting the previously suggested plumelets scenario for the origin of intraplate volcanism during the mid‐Cretaceous volcanic events. Our magnetic modeling suggests that the late‐stage volcanism does not overprint the remanant magnetization acquired by the Jurassic ocean crust in the Pigafetta Basin, and hence, marine magnetic anomalies recorded in the Jurassic basement are preserved. Also, the formerly identified Rough‐Smooth Boundary (RSB) is indistinguishable from any other rough‐smooth topographic boundaries throughout the survey area suggesting that the RSB is unlikely to be a Cretaceous sill‐Jurassic basement boundary. Lastly, the apparent ages and spatial distribution of volcanic features suggests a dynamic history of hydrothermal circulation in the Pigafetta Basin, indicating that hydrothermal circulation was ongoing well past 100 Ma.
Studying the Structural and Folding Features of Long‐Sequence Trichobrachin Peptides
Authors: Násztor Zoltán , Horváth János , Leitgeb Balázs 
Published: September 2015

AbstractIn this theoretical study, the folding processes of long‐sequence trichobrachin peptides (i.e., TB IIb peptides) were investigated by molecular dynamics methods. The formation of various helical structures (i.e., 310‐, α‐, and left‐handed α‐helices) was studied with regard to the entire sequence of peptides, as well as to each amino acid. The results pointed out that TB IIb molecules showed a propensity to form helical conformations, and they could be characterized by 310‐helical structure rather than by α‐helical structure. The formation of local (i.e., i←i+3 and i←i+4) as well as of non‐local (i.e., i←i+n, where n>4; and all i→i+n) H‐bonds was also examined. The results revealed that the occurrence of local, helix‐stabilizing H‐bonds was in agreement with the appearance of helical conformations, and the non‐local H‐bonds did not produce relevant effects on the evolution of helical structures. Based on the data obtained by our structural investigation, differences were observed between the TB IIb peptides, according to the type of amino acid located in the 17th position of their sequences. In summary, the folding processes were explored for TB IIb molecules, and our theoretical study led to the conclusion that these long‐sequence peptaibols showed characteristic structural and folding features.

AbstractDetailed GC and GC‐MS analyses of the essential oils and Et2O extracts of two Xeranthemum species – X. cylindraceum and X. annum – resulted in the identification of 254 components, in total. Terpenoids constituted the major part of both X. cylindraceum and X. annum essential oils and extracts (51.8–65.7%, and 50.7%, resp.). Among the sesquiterpenoids, the extracts of both investigated taxa contained the guaianolide xerantholide, its 11,13‐dihydro derivatives, and two additional sesquiterpene lactones: an eudesmanolide, 11,13‐dihydroisoalantolactone, and a pseudoguaianolide, confertin. The last two lactones and both isomers of 11,13‐dihydroxerantholide have not been previously detected in Xeranthemum species. The isolated extracts of X. cylindraceum and X. annum were tested in a broth microdilution assay against a panel of microorganisms. The tested extracts demonstrated significant antimicrobial inhibitory activity, ranging from 30 to 260 μg/ml, being most active against Bacillus cereus and Staphylococcus aureus, an important human pathogen, with MIC close in value to those of chloramphenicol. Chemotaxonomic significance of the sesquiterpene lactones' distribution in the taxa investigated in this study and those detected earlier in phylogenetically close species (up to the level of the tribe Cardueae) was also discussed.

AbstractBaccharis is a widespread genus belonging to the Asteraceae family that includes almost 400 species exclusively from the Americas. Even when studied in detail, the taxonomic classification among species from this genus is not yet fully defined. Within the framework of our study of the volatile composition of the Baccharis genus, four species (B. trimera, B. milleflora, B. tridentata, and B. uncinella) were collected from the ‘Campos de Cima da Serra’ highlands of the Brazilian state of Rio Grande do Sul. The aerial parts were dried and extracted by the simultaneous distillation extraction (SDE) procedure. This is the first time that SDE has been applied to obtain and compare the volatile‐extract composition in the Baccharis genus. Characterization of the volatile extracts allowed the identification of 180 peaks with many coeluting components; these latter being detailed for the first time for this genus. The multivariate statistical analyses allowed separating the volatile extracts of the four populations of Baccharis into two separate groups. The first one included the B. milleflora, B. trimera, and B. uncinella volatile extracts. The three species showed a high degree of similarity in their volatile composition, which was characterized by the presence of high contents of sesquiterpene compounds, in particular of spathulenol. The second group comprised the extract of B. tridentata, which contained α‐pinene, β‐pinene, limonene, and (E)‐β‐ocimene in high amounts.

Published: September 2015

AbstractThe five studied bacterial strains could produce volatile organic compounds (VOCs) that kill nematodes. Based on their 16S rRNA sequences, these strains were identified as Pseudochrobactrum saccharolyticum, Wautersiella falsenii, Proteus hauseri, Arthrobacter nicotianae, and Achromobacter xylosoxidans. The bacterial VOCs were extracted using solid‐phase micro‐extraction (SPME) and subsequently identified by GC/MS analysis. The VOCs covered a wide range of aldehydes, ketones, alkyls, alcohols, alkenes, esters, alkynes, acids, ethers, as well as heterocyclic and phenolic compounds. Among the 53 VOCs identified, 19 candidates, produced by different bacteria, were selected to test their nematicidal activity (NA) against Caenorhabditis elegans and Meloidogyne incognita. The seven compounds with the highest NAs were acetophenone, S‐methyl thiobutyrate, dimethyl disulfide, ethyl 3,3‐dimethylacrylate, nonan‐2‐one, 1‐methoxy‐4‐methylbenzene, and butyl isovalerate. Among them, S‐methyl thiobutyrate showed a stronger NA than the commercial insecticide dimethyl disulfide. It was reported for the first time here that the five bacterial strains as well as S‐methyl thiobutyrate, ethyl 3,3‐dimethylacrylate, 1‐methoxy‐4‐methylbenzene, and butyl isovalerate possess NA. These strains and compounds might provide new insights in the search for novel nematicides.

Published: September 2015

AbstractCarbene transfer to appropriate substrates is a highly versatile tool for the construction of carbon frameworks with increased functional and structural complexity. In this study, some novel cyclopropane derivatives were synthesized via carbenoid reactions and their further reactivities were investigated. (1E)‐Buta‐1,3‐dien‐1‐yl acetate was reacted with four different diazocarbonyl compounds, ethyl diazoacetate, dimethyl diazomalonate, 1‐diazo‐1‐phenylpropan‐2‐one, and methyl (3E)‐2‐diazo‐4‐phenylbut‐3‐enoate, in the presence of two catalysts. All synthesized substituted cyclopropanes were obtained chemoselectively with respect to less‐hindered CC bonds. Under the applied conditions, while cyclopropanes 7a and 7d underwent further reactions, cyclopropanes 7b and 7c were stable enough. Cyclopropanes 7a and an additional equivalent of ethyl diazoacetate yielded polyfunctionalized cyclohexenes. Cyclopropanes from methyl (3E)‐2‐diazo‐4‐phenylbut‐3‐enoate yielded polyfunctionalyzed cycloheptadiene isomers by Cope rearrangement.

Published: September 2015

AbstractThe first concise synthesis of the bidesmosidic oleanolic acid saponins 1–3 isolated from Fadogia ancylantha (Makoni tea) have been accomplished through a ‘one‐pot sequential glycosylation’ strategy with two glycosyl 1‐(trichloroacetimidate)s as glycosyl donors. The synthesized natural products 1–3 were then evaluated for their inhibitory activities against α‐glucosidase, α‐amylase, and lipase. Among the assayed compounds 1–3, compound 1 showed strong α‐glucosidase and α‐amylase inhibition, with IC50 values of 160 and 180 μM, respectively. Moreover, compounds 2 and 3 showed strong inhibition against α‐glucosidase and lipase, with the respective IC50 values of 170 and 190 μM, and 190 and 200 μM.

Factors influencing emigration of Ross's and snow geese from an Arctic breeding area
Authors: Wilson Scott , Alisauskas Ray T. , Kellett Dana K. 
Published: September 2015

ABSTRACTEmigration is one of the most difficult demographic rates to estimate, yet understanding movement among populations has important consequences for wildlife conservation. We studied factors that affected emigration by adult Ross's geese (Chen rossii) and lesser snow geese (C. caerulescens caerulescens) during a demographic study from 1997 to 2013 of nesting geese at the Karrak Lake colony south of Queen Maud Gulf in the Central Canadian Arctic. Rising abundance of both species in recent decades has led to concerns about their impacts on Arctic ecosystems. We used Burnham's model to estimate true survival and fidelity (i.e., the complement of emigration). Mean estimates of fidelity were higher for Ross's geese (male = 0.91 ± 0.02, female = 0.95 ± 0.01) than for snow geese (male = 0.76 ± 0.02, female = 0.90 ± 0.02). Fidelity declined with prior nesting season abundance in both species with evidence that a reduction in population size led to greater fidelity in the following year. Fidelity was positively influenced by mean nest success in the previous year with similar responses by both species. However, years of low nest success were more frequent for snow geese resulting in higher emigration. We expected that deeper snow before nesting would motivate greater emigration but found the opposite effect in both species, suggesting that individuals may be discouraged from dispersing in snow‐covered landscapes. We also tested whether a large decline in the number of snow geese nesting at Karrak Lake in 2007–2008 was related to a mass emigration event but found no evidence for a change in fidelity in these years. Moreover, survival of both species showed an increasing trend from 1997 to 2013 so the decline in nesting snow geese likely was an outcome of temporary non‐breeding, rather than emigration or death. The destination of emigrants remains unknown, but we expect this movement has broader consequences for metapopulation dynamics of light geese across the central Arctic. © 2015 Her Majesty the Queen in Right of Canada published on behalf of The Journal of Wildlife Management.
