Published: November 2021

Kabupaten Malang adalah daerah yang ikut serta dalam pemasok produksi padi di Negeri ini. Kabupaten Malang sendiri memiliki 33 Kecamatan yang sebagian besar penduduk nya bekerja sebagai petani padi. Dalam bertani padi ada kalanya di tiap-tiap kecamatan tersebut mengalami kenaikan ataupun penurunan produksi. Dalam pengolahan hasil produksi padi tersebut petani sendiri kadang tidak mengetahui hasil produksi padi di daerahnya. Dalam kondisi saat ini informasi sangat mendukung program ketahanan pangan dalam bidang pertanian. Pengumpulan informasi data produksi pertanian yang cepat dan akurat memudahkan dalam pengelolaan data. Dengan dibuatnya Sistem Informasi Geografis sangat membantu dalam pengolahan data produksi padi di Kabupaten Malang. Dengan adanya permasalahan tersebut maka dibuat sistem informasi geografis pemetaan hasil produksi padi di kabupaten malang dengan harapan dinas paertanian dapat mengelompokkan hasil produksi padi tiap kecamatan di kabupaten malang menggunakan metode clustering. Salah satu metode clustering yang digunakan pada sistem ini adalah metode k-means. Data yang diolah dalam penelitian ini yaitu data produksi padi tahun 2018-2020 dinas pertanian Kabupaten Malang. Sistem dibuat menggunakan website dengan framework Codeigniter, sedangkan untuk pemetaan produksi padi pada penelitian ini menggunakan Leaflet. Dari hasil pengujian sistem informasi geografis menggunakan K-Means Clustering dengan 3 cluster untuk pengelompokan hasil produksi padi di Kabupaten Malang, dengan menggunakan 99 sampel data, terdapat hasil pengelompokan sebanyak 44 (45%) masuk dalam kategori produksi banyak, 40 (40%) kategori produksi sedang dan 15 (15%) produksi kurang memuaskan. Berdasarkan hasil pengujian kinerja sistem dengan membandingkan pengelompokan secara manual atau data lama dengan pengelompokan pada sistem, sistem ini cukup baik dalam mengklasifikasi warga kurang mampu dengan tingkat akurasi 100%.

Taro and new cocoyam are root and leaf crops commonly grown in tropical to warm temperate regions. In Togo, they are neglected and underutilised. Here we report the genetic diversity of 26 accessions of taro and 101 accessions of new cocoyam. Analysis of simple sequence repeats revealed low polymorphic information content of 0.43 and 0.25 in taro and new cocoyam, respectively. PCA scatterplots and Neighbour Joining dendrograms based on the SSR data clustered accessions into groups that more-or-less correspond to morphological diversity in both species. AMOVA within and between morphological groups revealed greater variances within groups than between. This indicates weak genetic differentiation between morphological groups, particularly for taro. Genetic diversity was greater among taro cultivars. Taro has a longer history of introduction and dispersal in Africa, and has had more opportunity for multiple introduction and local cultivar development. Different strategies are suggested for future development of these crops in Togo and Africa. For taro, further studies of existing diversity and recent experimental introduction, has spread widely in Africa with little genetic diversity. For this crop, international collaboration is needed to clarify taxonomy, and to introduced further cultivars for evaluation under local conditions in Africa.

Two decades after the first record of the invasive mussel Corbicula fluminea (Müller, 1774) in Bulgaria in 2001, it has been found in many surface lotic and standing waters in the Bulgarian Danube River Basin.
The aim of the current study is to report the finding of C. fluminea in lotic environment of the East Aegean water basin in Bulgaria. Six new localities of the mussel, all situated in the lower stretches of the Tundzha (two) and Maritsa (four) River were registered. The distributional patterns of the mussel and the abundance of its populations in relation to the environmental conditions were analyzed. The adaptive character of the Corbicula, the possible path for invasion as well as the probability of rapid spread of the mussel in the largest rivers and their tributary systems in south-eastern part of Balkan Peninsula was discussed.
Long-term Spectroscopic Survey of the Pleiades Cluster: The Binary Population
Authors: Torres Guillermo , Latham David W. , Quinn Samuel N. 
Published: November 2021

Abstract
We present the results of a spectroscopic monitoring program of the Pleiades region aimed at completing the census of spectroscopic binaries in the cluster, extending it to longer periods than previously reachable. We gathered 6104 spectra of 377 stars between 1981 and 2021, and merged our radial velocities with 1151 measurements from an independent survey by others started three years earlier. With the combined data spanning more than 43 yr, we have determined orbits for some 30 new binary and multiple systems, more than doubling the number previously known in the Pleiades. The longest period is 36.5 yr. A dozen additional objects display long-term trends in their velocities, implying even longer periods. We examine the collection of orbital elements for cluster members, and find that the shape of the incompleteness-corrected distribution of periods (up to 104 days) is similar to that of solar-type binaries in the field, while that of the eccentricities is different. The mass-ratio distribution is consistent with being flat. The binary frequency in the Pleiades for periods up to 104 days is 25% ± 3% after corrections for undetected binaries, which is nearly double that of the field up to the same period. The total binary frequency including known astrometric binaries is at least 57%. We estimate the internal radial velocity dispersion in the cluster to be 0.48 ± 0.04 km s−1. We revisit the determination of the tidal circularization period, and confirm its value to be 7.2 ± 1.0 days, with an improved precision compared to an earlier estimate.

Abstract
In order to investigate the relation between magnetic structures and the signatures of heating in plage regions, we observed a plage region with the He i 1083.0 nm and Si i 1082.7 nm lines on 2018 October 3 using the integral field unit mode of the GREGOR Infrared Spectrograph (GRIS) installed at the GREGOR telescope. During the GRIS observation, the Interface Region Imaging Spectrograph obtained spectra of the ultraviolet Mg ii doublet emitted from the same region. In the periphery of the plage region, within the limited field of view seen by GRIS, we find that the Mg ii radiative flux increases with the magnetic field in the chromosphere with a factor of proportionality of 2.38 × 104 erg cm−2 s−1 G−1. The positive correlation implies that magnetic flux tubes can be heated by Alfvén wave turbulence or by collisions between ions and neutral atoms relating to Alfvén waves. Within the plage region itself, the radiative flux was large between patches of strong magnetic field strength in the photosphere or at the edges of magnetic patches. On the other hand, we do not find any significant spatial correlation between the enhanced radiative flux and the chromospheric magnetic field strength or the electric current. In addition to the Alfvén wave turbulence or collisions between ions and neutral atoms relating to Alfvén waves, other heating mechanisms related to magnetic field perturbations produced by interactions of magnetic flux tubes could be at work in the plage chromosphere.
Un marché très exclusif
Authors: Lepont Ulrike 
Published: November 2021

Cet article explore la question du pouvoir que peut conférer la maîtrise des modèles budgétaires à des experts qui cherchent à s’impliquer dans le processus d’élaboration de politiques publiques. Il montre que, dans le cas des réformes de la protection maladie menées aux États-Unis entre 1993 et 2010, cette compétence fut une ressource importante du fait de la centralité qu’ont acquise les enjeux budgétaires dans le processus législatif, mais aussi de la rareté des acteurs à qui est confiée la charge de la modélisation. Cette rareté est expliquée par l’hyper technicité de ces outils qui rend les compétences peu répandues, mais aussi par leur opacité qui, conformément à ce que Lucien Karpik décrit comme un marché « des singularités », conduit les commanditaires à s’en remettre à la réputation des prestataires. Les producteurs de modèles peuvent alors se servir de leur autorité pour promouvoir des programmes de réforme qui correspondent à leurs préférences politiques, outrepassant ainsi la mission purement technique à laquelle on associe généralement les modèles. Ces résultats sont tirés d’une enquête principalement qualitative, combinant entretiens et sources écrites (CV des experts, littérature grise, articles de presse).
Le modèle qui cache la forêt
Authors: Dolez Antoine 
Published: November 2021

Cet article analyse comment la mise à l’agenda du changement climatique modifie la recherche française sur les forêts. Historiquement structurée autour de deux communautés – sylvicole et écologique –, la recherche forestière s’oriente, sous l’égide du Groupe d’experts intergouvernemental sur l’évolution du climat (GIEC), vers le développement de modèles qui anticipent les dynamiques des forêts dans les climats futurs. Cet impératif modélisateur est porté par de nouveaux acteurs – statisticiens et modélisateurs – dont les modèles complexes occupent une place centrale dans l’organisation et le financement de la recherche, et bouleversent les territoires d’expertise des communautés de recherche forestière. Pour préserver leur juridiction, les communautés sylvicole et écologique critiquent la pertinence scientifique de ces modèles pour éclairer l’évolution des forêts à l’horizon 2100. Elles cherchent alors à imposer un autre agenda de recherche : un retour au terrain, à l’expérimentation et aux données anciennes. Cet article montre comment le statut de la modélisation et la nature des pratiques modélisatrices peuvent devenir un enjeu déterminant de démarcation entre des communautés de recherche concurrentes.

Abstract
Due to limited access to vaccines, many countries have only administered a single dose of the AZD1222, whereas the dosage intervals have increased ≥4 wk. We sought to investigate the immunogenicity of a single dose of vaccine at ≥16 wk postimmunization. Severe acute respiratory syndrome coronavirus 2–specific Abs in 553 individuals and Abs to the receptor-binding domain of the Wuhan virus (wild-type) and the variants of concern, angiotensin-converting enzyme 2 receptor blocking Abs ex vivo and cultured IFN-γ T cell (Homo sapiens) responses and B cell (H. sapiens) ELISPOT responses, were investigated in a subcohort. The seropositivity rates in those &gt;70 y of age (93.7%) was not significantly different compared with other age groups (97.7–98.2; Pearson χ2 = 7.8; p = 0.05). The Ab titers (Ab index) significantly declined (p &lt; 0.0001) with increase in age. A total of 18 of 69 (26.1%) of individuals did not have angiotensin-converting enzyme 2 receptor–blocking Abs, whereas responses to the receptor-binding domain of wild-type (p = 0.03), B.1.1.7 (p = 0.04), and B.1.617.2 (p = 0.02) were significantly lower in those who were &gt;60 y. Ex vivo IFN-γ T cell ELISPOT responses were seen in 10 of 66 (15.1%), whereas only a few expressed CD107a. However, &gt;85% had a high frequency of cultured IFN-γ T cell ELISPOT responses and B cell ELISPOTs. Virus-specific Abs were maintained at ≥16 wk after receiving a single dose of AZD1222, although levels were lower to variants of concern, especially in older individuals. A single dose induced a high frequency of memory T and B cell responses.

Background and purpose:
The preponderance of microbial infections remains a global challenge. In the present study, synthesis of novel cysteine-based antimicrobial agents and their biological evaluation is reported.

Experimental approach:
The reaction of p-toluenesulphonyl chloride with cysteine afforded 2-{[(4-methylphenyl)sulphonyl]amino}-3-sulphanylpropanoic acid (3) which was acetylated based on Lumiere-Barbier method using acetic anhydride. The ammonolysis of the acetylated compound (4) gave the carboxamide derivative (5) which reacted with aniline, aminopyridine and diaminopyrimidine via nickel catalyzed Buchwald-Hartwig amidation reaction to afford compounds 6a, 6b, and 6c, respectively. The compounds were characterized using FTIR, 1H-NMR, 13C-NMR, and elemental analysis. The in vitro antimicrobial activities were determined. Their physicochemical properties were generated in silico and the molecular docking studied bacterial and fungal infections.

Findings/Results:
Compounds 4, 6b, and 6c exhibited excellent in vitro antibacterial activities while compound 4 had the best antifungal activities. From the in silico antimicrobial results, compound 3 had a better binding affinity (-10.95 kcal/mol) than penicillin (-10.89 kcal/mol) while compounds 3 and 4 had binding affinities (-10.07 and -10.62kcal/mol) comparable to ketoconazole (-10.85 kcal/mol).

Conclusion and implication:
All the synthesized compounds exhibited significant antibacterial and antifungal activities and were confirmed to be potential antimicrobial agents.
An Application of the Integrated Behavioral Model for Water, Sanitation and Hygiene to Assess Perceived Community Acceptability and Feasibility of the Biosand Filter among Maasai Pastoralists in Rural Tanzania

ABSTRACT.
In addition to diarrheal disease risk, lack of access to safe water may have other indirect effects throughout one’s life, such as school and workplace absenteeism, leading to less economic productivity. In contexts with scarce resources and unsafe drinking water, household water treatment and safe storage options such as the Biosand filter (BSF) allows households to directly reduce contamination and increase the quality of their drinking water. This study aimed to develop an understanding of perceived community acceptability and feasibility related to pre- and post-implementation of a BSF pilot project in rural Maasai households in the Ngorongoro Conservation Area (NCA), Tanzania. The study was guided by the Integrated Behavioral Model for Water Sanitation and Hygiene interventions (IBM-WASH) to understand the various factors influencing end-user perceptions of the BSF. In-depth interviews, group discussions and think tanks were conducted among a cross-section of community members, stakeholders, and other actors from May 2016 to September 2017. The data were analyzed using a thematic content analysis approach. A range of perceived contextual, technological, and psychosocial factors were found to potentially affect the acceptability and feasibility of BSF adoption in the NCA, highlighting the complex layers of influences in the setting. Whilst the BSF is seemingly an accepted option to treat water within the NCA, the community identified key barriers that may lower BSF adoption. The application of the IBM-WASH model served as a useful framework for evaluating the introduction of the BSF, identifying insights into contextual, technological, and psychosocial community factors.

Published: November 2021

ABSTRACT.
Transovarial transmission (TOT) of dengue virus (DENV) in Aedes spp. is an important mechanism for DENV maintenance in nature and may be important in initiating outbreaks. The objective of this study was to explore the occurrence of TOT in wild Aedes albopictus populations in Cuba. Mosquito larvae were collected in Cotorro municipality, Havana, Cuba, and identified to species. Fifteen pools of Ae. albopictus each containing 30 larvae were processed for DENV detection by using conventional reverse transcription polymerase chain reaction (RT-PCR) and nested PCR. Four out of 15 pools processed were positive for DENV-3, but no other DENV serotype was detected. This is the first time TOT of DENV detected in Cuban field populations of Ae. albopictus, and this suggests that this species may be an important vector of DENV in Cuba.

ABSTRACT.
Quantitative polymerase chain reaction (qPCR) of dried blood spots (DBS) for pathogen detection is a potentially convenient method for infectious disease diagnosis. This study tested 115 DBS samples paired with whole blood specimens of children and adolescent from Burkina Faso, Sudan, and Madagascar by qPCR for a wide range of pathogens, including protozoans, helminths, fungi, bacteria, and viruses. Plasmodium spp. was consistently detected from DBS but yielded a mean cycle threshold (Ct) 5.7 ± 1.6 higher than that from whole blood samples. A DBS qPCR Ct cutoff of 27 yielded 94.1% sensitivity and 95.1% specificity against the whole blood qPCR cutoff of 21 that has been previously suggested for malaria diagnosis. For other pathogens investigated, DBS testing yielded a sensitivity of only 8.5% but a specificity of 98.6% compared with whole blood qPCR. In sum, direct PCR of DBS had reasonable performance for Plasmodium but requires further investigation for the other pathogens assessed in this study.
Femine Body in the Mass Culture of Iran: between Nudity and Marginalization
Authors: Kyrchanoff Maksym W. 
Published: November 2021

The author analyses the problems of visualisation and marginalisation of female corporeality in developments of Iranian political and cultural identity from the early modernisation project of the 19th century and the radical modernisation of the 1920s – 1970s to the Islamic Revolution of 1979, which changed significantly the vectors and trajectories of the visualisation of the female body in public spaces and the discourse of Iranian culture. The author believes that Iran / Persia in the 19th century belonged to the number of Muslim countries that were under stable European influences. Russia and Great Britain became the main sources of cultural changes. Cultural exchange with these countries stimulated changes in Persian identity. The author analyses the features of corporeality in the visual art of Iran from the Qajars to the Islamic revolution and its mutations during the process of radical Islamisation of the social life inspired by it. The author believes that the early modern project of the Qajars was the first attempt to visualise female corporeality and map in the centre of cultural coordinates which in fact simulated European discourse. The identity project of the Pahlavi period became an attempt to transform and adopt Western concepts to the Iranian national canon. The Islamic Revolution of 1979 marginalised the visual and visible forms of female corporeality, presented earlier in public and cultural spaces. The project of Islamisation inspired subordination of the female body, marginalising attempts to visualise in ways Western intellectuals did it. Modern feminine corporeality in Iranian culture develops as a dichotomy of official religious identity and its secular alternative, represented by the “high” cultural segments of the consumer society. The author analyses how and why Western strategies of visualisation of female corporeality coexist with its religious rejection. It is assumed that the Iranian mass culture assimilated Western practices of visualising femininity, although the official cultural discourse continues to reproduce the canon of the body imagined as predominantly religious construct.

Authors: Ramadhan Dimas Akbar 
Published: November 2021

The use of water reservoirs is increasingly diverse but the aims still to save clean water, making the competition between water reservoir producers in Indonesia more competitive. That is added with the emergence of various brands of new water reservoirs that are produced and circulated throughout Indonesia. Moreover, the types of water reservoirs that appear are also increasingly varied. The number of brands of water reservoirs in Indonesia with various types of marketing affects consumer buying interest in the water reservoir itself. This study aims to determine the effect of Electronic Word of Mouth and Brand Image on Buying Interest. By using associative methodology and in taking the sample using purposive sampling technique. The results of this study note that Electronic Word of Mouth and Brand Image simultaneously and partially affect Purchase Interest. The company should maintain and further improve the supporting factors in order to form a Brand Image that has a positive influence on buying interest from consumers.
