PEMANFAATAN JAMUR MIKORIZA UNTUK MENINGKATKAN PERTUMBUHAN DAN PRODUKSI TANAMAN JAGUNG (Zea mays L.)
Authors: Putri Wina Dewi , Susiawan Eddy 
Published: August 2021

Jagung (Zea mays L.) merupakan komoditas pangan sumber karbohidrat kedua setelah beras yang sangat penting untuk ketahanan pangan. Jagung juga berperan penting dalam industri pakan ternak dan industri pangan. Dalam kurun lima tahun terakhir, kebutuhan jagung nasional untuk bahan industri pakan, makanan dan minuman meningkat 10% —15% pertahun. Salah satu teknologi yang dapat meningkatkan produksi tanaman jagung adalah penggunaan jamur mikoriza. Tanaman yang bermikoriza tumbuh lebih baik dari tanaman tanpa mikoriza. Penyebab utama adalah mikoriza secara efektif dapat meningkatkan penyerapan unsur hara baik unsur hara makro maupun mikro. Selain daripada itu akar yang bermikoriza dapat menyerap unsur hara yang belum tersedia bagi tanaman. Pelaksanaan kegiatan budidaya ini dilakukan di lahan praktek Politeknik Pertanian Negeri Payakumbuh, Tanjung Pati, Kecamatan Harau, Kabupaten Limapuluh Kota, Sumatera Barat. Waktu pelaksanaan dimulai pada bulan September 2015 sampai bulan Januari 2016. Budidaya tanaman jagung dilakukan pada luas lahan 300 m2. Luas lahan yang digunakan untuk teknologi adalah 250 m2 dan tanpa teknologi seluas 50 m2. Berdasarkan hasil pengamatan dan uji statistik, penggunaan jamur mikoriza dapat meningkatkan pertumbuhan vegetatif yaitu tinggi tanaman dan generatif yaitu jumlah biji perbaris dan jumlah bobot 100 biji. Pada lahan teknologi diperoleh produksi sebanyak 132 kg/300 m2 (4,4 ton/ha), meningkat 22,85% dibandingkan produksi tanpa teknologi yaitu 108 kg/300 m2 (3,6 ton/ha).

Budidaya tanaman jagung dengan menggunakan kompos jerami merupakan suatu kegiatan yang mendasarkan kepada tingginya permintaan akan jagung yang ada di Kabupaten Limapuluh Kota. Hal lain yang menjadi dasar menerapkan teknologi ini adalah karena banyaknya jumlah petani padi di Kabupaten Limapuluh Kota tapi pemanfaatan limbah organik masih sangat rendah dan lebih banyak dibakar, yang dilakukan dalam luasan lahan 300 m2. Dilakukan di lahan Proyek Mahasiswa Wirausaha pada bulan septermber 2015 sampai bulan Januari 2016. Dari sumber yang didapat kandungan dalam jerami diantarnya yang paling menonjol adalah kandungan unsur N yang ada yaitu 1,57%. Hal ini menjadi salah satu langkah penting untuk melakukan budidaya yang efeisien dan hemat. Pelaksanaan kegiatan menunjukkan tanaman jagung yang diberi perlakuan teknologi kompos jerami memebrikan hasil yang rendah. Berdasakan kegiatan yang telah dilakukan, terdapat 2 fase pengamatan dari penggunaan kompos jerami dimana pada fase vegetatif (sebelum berbunga) pemberian kompos memberikan pengaruh yang nyata dimana pengamatan yang dilakukan adalah jumlah daun, lebar daun, panjang daun terpanjang. Pada fase generatif hasil pengamatan menunjukkan pemberian kompos jerami memberikan pengaruh yang tidak nyata terhadap jumlah baris per tongkol, biji per baris, berat 100 biji, dan hasil produksi yang didapat untuk pemberian kompos jerami adalah 264 kg/300 m2 (8,74 ton/ha) dan untuk lahan tanpa kompos jerami 234 kg/300 m2 (7,4 ton/ha).

Published: August 2021

Information technology can help older persons continue living independently and keep them active for many years. The aim of the present study is to understand the expectations of older people regarding information technology, how they perceive it, how useful they find it and how significant it is in their life. For this purpose, we interviewed 40 older people aged 65-93 who were attending day centers.
The findings, which were examined in light of the continuity theory presented by Atchley (1989), reveal different levels of resistance to technology that range from rejection and tendency to preserve previous familiar patterns to acceptance of the technology. Findings indicate cracks in the continuity strategy. The discourse about information technology among the older persons is ambivalent, incoherent, and laden with internal contradictions. Older people are immigrants to the new digital world; they do not speak its language and feel alienated from it, simultaneously accepting and rejecting it.

Published: August 2021

Background: Failure of the native aortic valve and degenerative anatomy of ascending aorta in patients with previous Tirone-David operation may represent a clinical challenge, because sometimes the risk of reoperation is prohibitive.Case: We described the case of a patient suffering from severe aortic valve regurgitation and pseudoaneurysm of the aortic arch, 6 years after cardiac surgery operation. The aim of this clinical case was to assess if the complex anatomy of aortic pseudoaneurysm and aortic root geometry can be accurately reproduced from contrast-enhanced computed tomography scan into a three-dimensional (3D) printed model. Based on this procedural method, with the aid of transesophageal 3D ultrasound, we efficaciously treated the patient percutaneously with a combination of transcatheter occluder device plus microcoil embolization and transfemoral aortic valve implantation. The patient was free from complications and the need to redo cardiac surgery.Conclusion: To the best of our knowledge, this is the first description of two simultaneous complications and their staged treatment in a patient with previous aortic valve-sparing operation. This is a useful report in a single 3D model applying such specific technology to these two simultaneous clinical settings.

Published: August 2021

Objective: The objective of the study was to develop an automatic quantitative approach to identify infants with abnormal movements of the limbs at term equivalent age (TEA) compared with general movement assessment (GMA).Methods: GMA was performed at TEA by a trained operator in neonates with neurological risk. GMs were classified as normal (N) or abnormal (Ab), which included poor repertoire and cramped synchronized movements. The signals from four micro-accelerometers placed on all limbs were recorded for 10 min simultaneously. A global index (KC_index), quantifying the characteristics of individual limb movements and the coordination among the limbs, was obtained by adding normalized kurtosis of the distribution of the first principal component of the acceleration signals to the cross-correlation of the jerk for the upper and lower limbs.Results: Sixty-eight infants were studied. A KC_index cut-off of 201.5 (95% CI: 199.9–205.0) provided specificity = 0.86 and sensitivity = 0.88 in identifying infants with Ab movements.Conclusions: KC_index provides an automatic and quantitative measure that may allow the identification of infants who require further neurological evaluation.

Published: August 2021

Background:Brief episodes of atrial fibrillation (AF) may evolve into longer AF episodes increasing the chances of thrombus formation, stroke, and death. Classical methods for AF detection investigate rhythm irregularity or P-wave absence in the ECG, while deep learning approaches profit from the availability of annotated ECG databases to learn discriminatory features linked to different diagnosis. However, some deep learning approaches do not provide analysis of the features used for classification. This paper introduces a convolutional neural network (CNN) approach for automatic detection of brief AF episodes based on electrocardiomatrix-images (ECM-images) aiming to link deep learning to features with clinical meaning.Materials and Methods:The CNN is trained using two databases: the Long-Term Atrial Fibrillation and the MIT-BIH Normal Sinus Rhythm, and tested on three databases: the MIT-BIH Atrial Fibrillation, the MIT-BIH Arrhythmia, and the Monzino-AF. Detection of AF is done using a sliding window of 10 beats plus 3 s. Performance is quantified using both standard classification metrics and the EC57 standard for arrhythmia detection. Layer-wise relevance propagation analysis was applied to link the decisions made by the CNN to clinical characteristics in the ECG.Results:For all three testing databases, episode sensitivity was greater than 80.22, 89.66, and 97.45% for AF episodes shorter than 15, 30 s, and for all episodes, respectively.Conclusions:Rhythm and morphological characteristics of the electrocardiogram can be learned by a CNN from ECM-images for the detection of brief episodes of AF.

Published: August 2021

Introduction: Healthcare workers are the critical frontline workforce of the COVD-19 pandemic and are considered a target group for vaccination. Hesitancy to vaccinate is a major concern that can jeopardize the vaccination programme. The hesitancy rates in the general population and healthcare workers (HCWs) vary globally, and more importantly, hesitancy in HCWs is of particular concern, as it can influence the wider population.Materials and Methods: The present study evaluated the vaccine hesitancy rate and its sociodemographic and attitudinal factors among the HCWs in the state of Qatar. We conducted a national cross-sectional survey using a validated hesitancy measurement tool between October 15 and November 15, 2020. A total of 7,821 adults above the age of 18 years out of the 2.3 million adult Qatari residents completed the survey. While majority of the participants were from the general public, 1,546 participants were HCWs. Sociodemographic data, along with attitudes and beliefs around COVID-19 vaccination, were collected from the respondents.Results: We found that 12.9% of the study participants showed vaccine hesitancy, defined as definitely or probably will not take the vaccine if offered, and 25.31% reported that they were unsure about the uptake of the COVID-19 vaccine. Female respondents were more hesitant toward the vaccine. Safety and efficacy concerns of vaccine were the significant predictors of vaccine hesitancy. The primary predictor for vaccine acceptance was a better understanding of the disease and vaccine.Discussion: Overall, 1 in 8 HCWs were reluctant to get vaccinated against COVID-19, mainly due to concerns about the vaccine's efficacy and safety. Education about the vaccine's safety and efficacy can potentially improve acceptance among healthcare workers.

Published: August 2021

Verticillium wilt (VW) is a typical fungal disease affecting the yield and quality of cotton. The Trichome Birefringence-Like protein (TBL) is an acetyltransferase involved in the acetylation process of cell wall polysaccharides. Up to now, there are no reports on whether the TBL gene is related to disease resistance in cotton. In this study, we cloned a cotton TBL34 gene located in the confidence interval of a major VW resistance quantitative trait loci and demonstrated its relationship with VW resistance in cotton. Analyzing the sequence variations in resistant and susceptible accessions detected two elite alleles GhTBL34-2 and GhTBL34-3, mainly presented in resistant cotton lines whose disease index was significantly lower than that of susceptible lines carrying the allele GhTBL34-1. Comparing the TBL34 protein sequences showed that two amino acid differences in the TBL (PMR5N) domain changed the susceptible allele GhTBL34-1 into the resistant allele GhTBL34-2 (GhTBL34-3). Expression analysis showed that the TBL34 was obviously up-regulated by infection of Verticillium dahliae and exogenous treatment of ethylene (ET), and salicylic acid (SA) and jasmonate (JA) in cotton. VIGS experiments demonstrated that silencing of TBL34 reduced VW resistance in cotton. We deduced that the TBL34 gene mediating acetylation of cell wall polysaccharides might be involved in the regulation of resistance to VW in cotton.

Published: August 2021

Various factors are responsible for injuries that occur in the U.S. Army soldiers. In particular, rucksack load carriage equipment influences the stability of the lower extremities and possibly affects gait balance. The objective of this investigation was to assess the gait and local dynamic stability of the lower extremity of five subjects as they performed a simulated rucksack march on a treadmill. The Motek Gait Real-time Interactive Laboratory (GRAIL) was utilized to replicate the environment of the rucksack march. The first walking trial was without a rucksack and the second set was executed with the All-Purpose Lightweight Individual Carrying Equipment (ALICE), an older version of the rucksack, and the third set was executed with the newer rucksack version, Modular Lightweight Load Carrying Equipment (MOLLE). In this experiment, the Inertial Measurement Unit (IMU) system, Dynaport was used to measure the ambulatory data of the subject. This experiment required subjects to walk continuously for 200 seconds with a 20kg rucksack, which simulates the real rucksack march training. To determine the dynamic stability of different load carriage and normal walking condition, Local Dynamic Stability (LDS) was calculated to quantify its stability. The results presented that comparing Maximum Lyapunov Exponent (LyE) of normal walking was significantly lower compared to ALICE (P=0.000007) and MOLLE (P=0.00003), however, between ALICE and MOLLE rucksack walking showed no significant difference (P=0.441). The five subjects showed significantly improved dynamic stability when walking without a rucksack in comparison with wearing the equipment. In conclusion, we discovered wearing a rucksack result in a significant (P < 0.0001) reduction in dynamic stability.

Published: August 2021

Goal. To determine the number and harmfulness of the main phytophages on peach cultivars of different ripening terms in order to plan measures to protect the crop from pest damage.
Methods. Laboratory-field. The research was carried out in peach orchards of the Scientific and Production Site «Naukova» of Melitopol Fruit Growing Research Station named after M.F. Sydorenka of Institute of Horticulture of NAAS according to generally accepted methods. Monitoring of the number of phytophages was performed on peach cultivars of different ripening terms: Iiun`s`kyi rannii, Melіtopol’s’kyi iasnyi, Charivnyk, Zlatodar, Vireneia, Redhaven, Spokusa, Zolotystii, Mriia and Yuvileinyi Sydorenka during bud swelling, inflorescence opening (pink tip), flowering, growth and maturations of the fruits.
Results. Entomoacarocenosis of peach plantations has 15 species of insects pests and 2 species of mites. During the flowering period, the main harmful species was Epicometis hirta Poda., the number of imagoes in different cultivars was 0.3—5.8 specimens/100 flowers. Population intensity of peach trees with green peach aphids (Myzodes persicae Sulz.) for certain cultivars reached the level of 1.9 points, mealy plum aphid (Hyalopterus pruni Geoffr.) — did not exceed 0.8 points. Density of mites, Thrips fuscipennis Haliche and Typhlocyba rosae L. varied in the range of 0.4—2.5; 0.8—2.4; 0.5—1.6 specimen/leaf, respectively. The main fruit-damaging pests in peach orchards were oriental fruit moth (Grapholitha molesta Busck.) and peach twig borer (Anarsia lineatella Zell.). The degree of fruit damage by Lepidoptera pest oriental fruit moth on early-ripening peach cultivars was 3.0—4.0%, increased on medium- and late-ripening cultivars to 6.8% and 11.7%, respectively. The level of fruit damage by peach twig borer compared to the eastern fruit moth was 2.8—10.7 times lower, depending on the cultivar.
Conclusions. In the conditions of the South of Ukraine, 15 insect pests and 2 species of mites were recorded in peach orchards. During the growing season, the number of most species of phytophagous, including weevils, leafroller moths, mites, thrips, Typhlocyba rosae on different peach cultivars did not exceed the economic threshold of harmfulness. During the flowering period, Epicometis hirta was the threat to peach orchards. In the summer of 2019, the harmful effects of sucking phytophages, in particular aphids, led to delayed growth and development of shoots, deformation of leaves. The main species of pests that reduced the yield and fruit quality were oriental fruit moth and peach twig borer.
L’avenir de l’intermédiation financière en Europe
Authors: Beau Denis 
Published: August 2021

L’intermédiation financière européenne et la monnaie sortiront profondément remodelées des transformations en cours, dont la crise de la Covid-19 constitue un facteur d’accélération. Au lieu d’éliminer un modèle d’intermédiation centré sur les banques, ces transformations peuvent conduire à rebattre les cartes autour de quatre grands modèles, au bénéfice de meilleures expériences utilisateurs, d’un financement plus diversifié de l’économie et d’une plus grande efficience du système financier. Cependant, ces transformations sont aussi porteuses de perturbations et de risques d’ampleur potentiellement systémique. Dans ce contexte, le rôle des régulateurs, des superviseurs et des banques centrales est de contribuer à maintenir la confiance et d’encourager l’innovation en adaptant leurs actions pour garantir une bonne maîtrise de ces risques.

Published: August 2021

Après une décennie durant laquelle la collecte de l’assurance vie avait bien résisté à la baisse continue des taux d’intérêt, leur entrée en territoire négatif en 2019 a révélé quelques limites de son modèle d’affaires. En effet, l’apparition de taux d’intérêt nominaux négatifs accroît la baisse du taux de rendement de l’actif des assureurs vie ; les engagements passés pris en matière de taux techniques limitent les baisses du taux de revalorisation ; la rémunération annuelle de ces contrats d’assurance vie est un facteur d’attractivité de la clientèle et de concurrence, ce qui réduit, toutes choses égales par ailleurs, le potentiel de baisse du taux de revalorisation. Dans cet article, nous analysons les mécanismes, par lesquels la baisse et l’environnement durable de bas taux d’intérêt ont affecté le bilan des assureurs vie, affectent la viabilité de leur modèle d’affaires, et les défis auxquels ils sont confrontés pour le faire évoluer.
