Authors: KAPLAN Hatice Elanur , GÜRBÜZ Esen
Published: December 2020

There are different theoretical models regarding the determinants of consumers’ intention to use technology and their use behavior. The Unified theory of acceptance and use of technology-2 (UTAUT-2) model explains the variance in behavioral intention and technology use variables in pursuit of a consumer-centric model. This research study aims to figure out the determinants and impacts of individuals’ intention to use mobile banking and their use behaviors within the context of Turkey. The data of the study was obtained from 684 participants aged 18 years or older in April-June 2018 via an online survey method. Findings of the research study reveal that the behavioral intention of using mobile banking is influenced by trust, social influence, price value, facilitating conditions, performance expectancy, and habit; whereas habit and trust affect both use behavior and behavioral intention. Furthermore, moderator impacts of trust and age as well as hedonic motivation and age on behavioral intention, whereas moderator impacts of habits and age on use behavior are determined. No significant relationship is found between the behavioral intention of using mobile banking and the use behavior.

Authors: Zhu Jian , Huang Jing
Published: December 2020

Methylguanidinium is an important molecular ion which also serves as the model compound for arginine side chain. We studied the structure and dynamics of methylguanidium ion at the air/water interface by molecular dynamics simulations employing the Drude polarizable force field. We found out that methylguanidinium accumulate on the interface with a majority adopting tilted conformations. We also demonstrated that methylguanidinium and guanidinium ions have different preference towards the air/water interface. Our results illustrate the importance to explicitly include the electronic polarization effects in modeling interfacial properties.

Published: December 2020

Silicon has been investigated as promising anode materials in lithium-ion batteries due to its high theoretical specific capacity. Nonetheless, high-capacity Si nanoparticles succumb to limited electrical conductivity, drastic volume change, and harsh aggregation upon cycling. In this paper, a unique multicoated composite is fabricated through innovative, simple, atmospheric pressure, and cost-effective atmospheric pressure aerosol-assisted vapor deposition (APAAVD). The fabrication method is reported for the first time with a well-distributed graphene nanoplatelets/nano-silicon composite layer through the processing with an organic solvent. The plane of the layers facilitates high rate capability, whereas the voids between the layers buffer volume expansion of silicon for good cycling performance. The multicoated composite anode (10 wt.% Si) presents a specific capacity of ~500 mAh g-1 at 0.17 A/g and capacity retention of 85.8 % after 500 discharge/charge cycles. The facile method preserves the combined advantages of atmospheric pressure chemical vapor deposition and aerosol-assisted chemical vapor deposition, offering an encouraging research arena for initial laboratory tests in rechargeable Li-ion batteries. Besides, two approaches for the presentation of cyclic discharge/charge patterns are proposed with generalized algorithms through linear algebra.

Organic-inorganic hybrid materials are nowadays intensely studied for potential applications in heterogeneous catalysis because their properties and catalytic behavior differ from pristine inorganic counterparts. The organic groups at the catalyst surface can modify not only its hydrophilicity, but also acidity, hydrothermal stability, porosity, etc. In some cases, such properties alteration leads to improved catalytic performance in terms of activity, selectivity, or stability. However, the choice of organic groups stays relatively narrow, as most reports focus on pendant methyl groups. Here, a series of mesoporous hybrid aluminosilicate materials containing various organic groups was prepared in one pot by non-hydrolytic sol-gel (NHSG). Both aromatic and aliphatic, pendant and bridging organic groups were incorporated. The presence of the organic groups in the bulk and at the outermost surface of the materials was verified by solid-state NMR and ToF-SIMS, respectively. Aluminum is mostly incorporated in tetrahedral coordination in the hybrid silica matrix. The organically modified mesoporous aluminosilicate samples were tested as catalysts in the gas phase ethanol dehydration (which relies on solid acids) and most of them outperformed the purely inorganic catalyst benchmark. While a direct influence of surface hydrophilicity or hydrophobicity (as probed by water sorption and water contact angle measurements) appeared unlikely, characterization of acidity (IR-pyridine) revealed that the improved performance for hybrid catalysts can be correlated with a modification of the acidic properties. In turn, acidity is determined by the quality of the dispersion of Al centers in the form of isolated sites in the hybrid silica matrix. All in all, this study establishes a "ranking" for a variety of organic groups in terms of their effect on gas-phase ethanol dehydration to ethylene; ethylene yield decreases in this order: bridging xylylene ≈ pendant methyl > pendant benzyl > bridging methylene ≈ inorganic benchmark (no organic groups) > bridging ethylene.

Severe cases of coronavirus disease 2019 (COVID-19), caused by infection with SARS-Cov-2, are characterized by a hyperinflammatory immune response that leads to numerous complications. Production of proinflammatory neutrophil extracellular traps (NETs) has been suggested to be a key factor in inducing a hyperinflammatory signaling cascade, allegedly causing both pulmonary tissue damage and peripheral inflammation. Accordingly, therapeutic blockage of neutrophil activation and NETosis, the cell death pathway accompanying NET formation, could limit respiratory damage and death from severe COVID-19. Here, we demonstrate that synthetic glycopolymers that activate the neutrophil checkpoint receptor Siglec-9 suppress NETosis induced by agonists of viral toll-like receptors (TLRs) and plasma from patients with severe COVID-19. Thus, Siglec-9 agonism is a promising therapeutic strategy to curb neutrophilic hyperinflammation in COVID-19.

Published: December 2020

The conventional method of assigning formal oxidation states (FOS) to metals and ligands is an important tool for understanding and predicting chemical reactivity, in particular in catalysis research. For complexes containing redox-noninnocent ligands, the oxidation state of the ligand can be ambiguous (i.e. their spectroscopic oxidation state can differ from the formal oxidation state), and thus frustrates the assignment of the oxidation state of the metal. A quantitative correlation between empirical metric data of redox active ligands and their oxidation states using a metrical oxidation state (MOS) model has been developed for catecholate and aminophenolate derived ligands by Brown. In the present work, we present a MOS model for 1,4-diazabutadiene (DADn) ligands. The model is based on a similar approach as reported by Brown, correlating the intra-ligand bond lengths of the DADn moiety in a quantitative manner to the MOS using geometrical information from X-ray structures in the Cambridge Crystallographic Data Center (CCDC) database. However, accurate determination of the MOS of these ligands turned-out to be dependent the coordination mode of the DAD2- moiety, which can adopt both a planar κ2-N2-geometry and a η4-N2-C2 π-coordination mode in (transition) metal complexes in its doubly reduced, dianionic enediamide oxidation state. A reliable MOS model was developed taking the intrinsic differences in intra-ligand bond distances between these coordination modes of the DAD2‒ ligand into account. Three different models were defined and tested using different geometric parameters (C=C→M distance, M-N-C angle, M-N-C-C torsion angle) to describe the C=C backbone coordination to the metal in the η4-N2-C2 π-coordination mode of the DAD2‒ ligand. Statistical analysis revealed that the C=C→M distance best describes the η4-N2-C2 coordination mode, using a cut-off value of 2.46 Å for π-coordination. The developed MOS model was used to validate the oxidation state assignment of elements not contained within the training set (Sr, Yb and Ho), thus demonstrating the applicability of the MOS model to a wide range of complexes. Chromium complexes with complex electronic structures were also shown to be accurately described by MOS analysis. Furthermore, it is shown that a combination of MOS analysis and FOD calculations provide an inexpensive method to gain insight into the electronic structure of singlet spin state (S = 0) [M(trop2dad)] transition metal complexes showing multireference character.

Published: December 2020

Proteolysis is one of the most important protein post-translational modifications (PTMs) that influences the functions, activities, and structures of nearly all proteins during their lifetime. This irreversible PTM is regulated and catalyzed by proteases through hydrolysis reaction in the process of protein maturation or degradation. The identification of proteolytic substrates is pivotal in understanding the specificity of proteases and the physiological role of proteolytic process. However, tracking these biological phenomena in native cells is very difficult due to their low abundances. Currently, no efficient methods are available to identify proteolytic products from large-scale samples. To facilitate the targeted identification of low-abundant proteolytic products, we devise a strategy incorporating a novel biotinylated reagent PFP (pentafluorophenyl)-Rink-biotin to specifically target, enrich and identify proteolytic N-terminus. Within the PFP-Rink-biotin reagent, an MS-cleavable feature is designed to assist in the unambiguous confirmation of the enriched proteolytic N-termini. This is the first reported study of identifying proteolytic N-terminus by MS-cleavable feature widely adopted in studying low-abundant protein PTMs and cross-linking/MS. The proof-of-concept study was performed with multiple standard proteins whose N-terminus were successfully modified, enriched and identified by a signature ion (SI) in the MS/MS fragmentation, along with the determination of N-terminal peptide sequences by multistage tandem MS of the complementary fragment generated after the cleavage of MS-cleavable bond. For large-scale application, the enrichment and identification of protein N-termini from Escherichia.coli cells were demonstrated along with a bioinformatics workflow. We believe this method can be very useful to locate proteolytic products in native cellular environment with high confidence.

Published: December 2020

In Algeria, soil erosion has experienced a spectacular extension, it is therefore imperative to assess the effects of this phenomenon. The purpose of this study is to assess soil loss rate using a GIS/USLE approach at the Mellegue watershed, northeast of Algeria. Geographic Information System techniques have been adopted to process data obtained at the study watershed, of reasonable spatial mapping, for the application of the RUSLE model. The model is a multiplication of the five erosion factors, namely rainfall erosivity, soil erodibility, slope and length of slope, plant cover and anti-erosion practices. Each of these factors has been expressed as a thematic map. The resulting soil loss map, with mean erosion rate of 20.40 T/ha/year, shows very low erosion (≤ 7 T/ha/year) which covers 64.60% of the total area of the basin, and very high erosion (> 60 T/ha/year) which does not exceed 4.80% of the basin area. The results indicate that Chabro and downstream Mellegue sub-watersheds face the greatest risk of soil erosion compared to Meskiana sub-basin, with contributions of 14.20 % and 12.90 % of their basin areas respectively. This is mainly due to natural factors and anthropogenic activities without appropriate conservation practices of agricultural land.

Identification and mapping of landslide is essential for landslide risk and hazard assessment. This paper gives information on the uses of landsat imagery for mapping landslide areas ranging in size from safe area to highly prone areas. Landslide mitigation largely depends on the understanding of the nature of the factors namely: slope, soil type, lineament, lineament density, elevation, rainfall and vegetation. These factors have direct bearing on the occurrence of landslide. Identification of these factors is of paramount importance in setting out appropriate and strategic landslides control measures. Images for this study was downloaded by using remote sensing with landsat 8 ETM and aerial photos using ArcGIS 10.7 and Surfer 8 software, while Digital Elevation Model (DEM) and Google EarthPro TM were used to produce slope, drainage, lineament and elevation. From the processed landsat 8 imagery, landslide susceptibility map was produced, and landslide was category into various class; low, medium and high. From the study, it was observed that Enugu and Anambra state ranges from high to medium in terms of landslide susceptibility, Imo state ranges from medium to low.

Posyandu Model for Children Based on Stimulus Growth using the UCIL Method Influences on the Level of Mother's Knowledge
Authors: Taukhit Taukhit , Haryono Rudi
Published: December 2020

One of the problems with children's health is the relatively high development delay. The delay in child development is influenced by the growth and development stimulus of the parent's child. Efforts to reduce child developmental disorders can be increased through the Posyandu program. The existing Posyandu needs to be remodeling so that it can be an approach to optimizing children's growth and development. The approach to optimizing the achievement of child development tasks through the Posyandu program that emphasizes UCIL activities is expected to be one way to overcome the problem of delayed child development. The purpose of this study was to determine the effect of the growth and development stimulus-based posyandu for toddlers with the UCIL method on increasing maternal knowledge in child development. This study used a quasi-experimental design in the form of a pretest - post test intervention with a control group. The study population was mothers with toddlers who actively attended Posyandu.

One of the most important food crops in the world, the potato (Solanum tuberosum L.) is infected with many viruses, of which the y virus (Potato virus Y, PVY) is the most important economically, causing significant crop losses. Several alternative methods of dsRNA delivery have been tested, with the most promising being spray - induced gene silencing (SIGS). The results showed a high effect of preventive use of dsRNA. Treatment with the initial working concentration of dsRNA protected 100% and 65% of plants from virus propagation for 14 and 21 days, respectively, and 65% of plants were protected by the minimum tested concentration (10 ng/MCL) for 14 days. Therapeutic use of dsRNA 3 days after inoculation did not significantly affect the dynamics of virus accumulation in the plant. Thus, in the course of the experiment, a high biological antiviral effectiveness of dsRNA was demonstrated in the preventive treatment of potato plants against the background of artificial infection of plants with the PVY virus.

Soybean has an ecological adaptability due to the deep selectivity of this crop in relation to the specific features of the growing zone. At the same time, it makes increased demands on heat and moisture, especially during certain "critical" periods of growth and development. The lower threshold of active average daily temperatures is 15–17oC, and for full maturation of ultra-ripe and early-maturing varieties, the sum of active temperatures of 1700–2100oС is required. Assessment of the agro-climatic resources of the Ryazan region indicates the possibility of growing precocious soybean varieties here. The limiting indicator in some critical periods may be insufficient moisture. As a result of the conducted research, it was found that soybean varieties of the Northern ecotype are able to form a stable yield in the conditions of the Ryazan region. At the same time, the lesser response to changes in agroclimatic conditions was shown by the Kasatka variety, which showed the shortest growing season and yield at the level of 1.00 t / ha. The Georgiya variety reacted more than any other to changes in weather conditions, its yield was from 1.24 to 1.72 t/ha over the years of research.
