Published: December 2022

Several methods for non-destructive mass measurements on single, trapped nanoparticles in the megadalton(MDa) to gigadalton (GDa) mass ranges are demonstrated, and the trade-offs between speed, precision, and ease of use are discussed. Charged nanoparticles are introduced into vacuum by electrospray ionization, and trapped in a quadrupole ion (Paul) trap, with detection by light scattering. Four different methods for measuring the mass/charge ratios of trapped particles are discussed, all based on measuring the secular frequency for motion of the particle in the trap, working in either the time or frequency domains. The charge is then measured by driving single electron charge changes using either a discharge or vacuum ultraviolet lamp. Several related topics such as the effects of pressure on secular resonance width and the spectrum of simultaneously trapped particles are also discussed.
Towards uncoding hepatotoxicity of approved drugs through navigation of multiverse and consensus chemical spaces
Authors: López-López Edgar , Medina-Franco José L.
Published: December 2022

Drug-induced liver injury (DILI) is the principal reason for failure in developing drug candidates. It is the most common reason to withdraw from the market after a drug has been approved for clinical use. Therefore, a current challenge is enhancing the accuracy of DILI events' predictive models. In this context, data from animal models, liver function tests, and chemical properties could complement each other to understand DILI events better and prevent them. Since the chemical space concept improves decision-making drug design related to the prediction of structure-property relationships, side effects, and polypharmacology drug activity (uniquely mentioning the most recent advances), it is an attractive approach to combining different phenomena influencing DILI events (e.g., individual “chemical spaces”) and exploring all events simultaneously in an integrated analysis of the DILI-relevant chemical space. However, currently, no systematic methods allow the fusion of a collection of different chemical spaces to collect different types of data on a unique chemical space representation, namely "consensus chemical space." This study is the first report that uses the data fusion concept to combine different chemical spaces to facilitate the analysis and prediction of DILIrelated events. The present work remarks the importance of analyzing together in vitro and chemical data (e.g., topology, bond order, atom types, presence of rings, ring sizes, and aromaticity of compounds encoded on RDKIT fingerprints). These properties could be aimed at improving the understanding of DILI events.

Published: December 2022

В рамках электронно-статистического метода проведены вычисления межфазной энергии низкотемпературной модификации титана на границе с неполярными органическими жидкостями, получены поправки к межфазной энергии на дисперсионное взаимодействие ячеек Вигнера-Зейтца и осцилляцию электронной плотности в переходном слое, поляризацию поверхностных ионов металла и органической жидкости в поле полубесконечного металла. При расчете межфазной энергии рассматриваются изменения всех компонентов энергии металлической связи в переходном слое - собственные энергии электронного газа, энергии взаимодействия электронного газа с ионами. Установлено влияние органической жидкости на ориентационную зависимость межфазной энергии альфа-титана и поправок к межфазной энергии с учетом диэлектрической проницаемости органической жидкости. Показано, что дисперсионная и осцилляционная поправки увеличивают межфазную энергию, а поляризационная поправка снижает межфазную энергию. Для этой структуры титана получена резкая анизотропия межфазной энергии и поправок.

Calculations of the interphase energy of low-temperature modification of titanium at the boundary with nonpolar organic liquids are carried out within the framework of the electron-statistical method, corrections to the interphase energy for the dispersion interaction of Wigner-Seitz cells and the electron density oscillation in the transition layer, the polarization of surface metal ions and organic liquid in the field of a semi-infinite metal are obtained. When calculating the interphase energy, changes in all components of the metal bond energy in the transition layer are considered - the eigenenergies of the electron gas, the energies of the interaction of the electron gas with ions. The effect of an organic liquid on the orientational dependence of the interphase energy of alpha-titanium and the corrections to the interphase energy taking into account the permittivity of the organic liquid is established. It is shown that the dispersion and oscillation corrections increase the interphase energy, and the polarization correction reduces the interphase energy. A sharp anisotropy of the interphase energy and corrections is obtained for this titanium structure.
ON THE POSSIBILITY OF CONTROLLING THE BAND GAP IN GRAPHENE
Authors: Ахматов Зейтун Ануарович , Ахматов Зариф Ануарович
Published: December 2022

Используя расчеты из первых принципов была исследована возможность управления электронной зонной структурой однослойного графена. Показано, что при адсорбции атомов калия на поверхность графена в его электронном спектре появляется энергетическая щель. Также замечено, что величина запрещенной зоны сильно зависит от количества адсорбированных атомов, а именно, при увеличении количества адсорбируемых атомов запрещенная зона в графене может как увеличиваться, так и исчезать. Так, например, когда на 32 атома углерода в решетке графена приходится один атом калия, величина запрещенной зоны составляет ΔE = 0,1 эВ. Увеличение числа атомов калия до двух приводит к исчезновению энергетической щели, тогда как для трех атомов калия она составляет ΔE = 0,22 эВ. Следует также отметить, что появление запрещенной зоны при адсорбции не приводит к нарушению симметрии графеновых подрешеток. Данное наблюдение представляется нам интересным, так как по мнению многих авторов, именно нарушение симметрии подрешеток является основной причиной появления запрещенной зоны в графене.

Using first principles calculations, the possibility of controlling the electronic band structure of the single-layer graphene was investigated. It is shown that when potassium atoms are adsorbed on the graphene surface, an energy gap appears in its electronic spectrum. It was also observed that the band gap strongly depends on the number of adsorbed atoms, namely, with an increase in the number of adsorbed atoms, the band gap in graphene can either increase or disappear. For example, when there is one potassium atom per 32 carbon atoms in the graphene lattice, the band gap is ΔE = 0,1 eV. An increase in the number of potassium atoms to two leads to disappearance of the energy gap, while for three potassium atoms ΔE = 0,22 eV. It should also be noted that the appearance of a band gap during adsorption does not break the symmetry of the graphene sublattices. This observation seems interesting to us, since according to many authors, it is the break of the sublattices symmetry that is the main reason for the appearance of a band gap in graphene.

Методом горения нитрат-органических прекурсоров разного состава были синтезированы образцы манганита лантана, допированного стронцием. Процесс горения реализовали в условиях воздействия внешнего переменного электромагнитного поля и в его отсутствие. Обнаружено, что в ходе горения прекурсоров происходит термохимическое генерирование зарядов, зафиксированное как разность потенциалов прекурсор-земля. Показано, что состав исходного прекурсора (органический компонент и его количество), а так же присутствие внешнего переменного электромагнитного поля оказывают влияние на величину возникающей разности потенциалов, варьировавшейся от -7 до 125 B. Наличие внешнего поля приводило к сдвигу возникающей разности потенциалов в сторону положительных значений. Показана взаимосвязь между изученными электромагнитными свойствами (намагниченность насыщения, коэрцитивная сила, температура Кюри) полученных образцов и разностью потенциала прекурсор - земля, возникающей в ходе синтеза. Значения температуры Кюри варьировались в области 38-79°C для образцов, полученных под влиянием переменного электро-магнитного поля, и 49-104°C - в его отсутствие.

Lanthanum manganite doped with strontium samples were synthesized by the combustion method of nitrate-organic precursors of different composition. The combustion process was realized under the influence of an external alternating electromagnetic field and in its absence. It was found that thermochemical generation of charges occurs during precursor’s combustion, recorded as a potential difference of precursor-earth. It is shown that the composition of the initial precursor (organic component and its quantity), as well as the presence of an external alternating electromagnetic field, affect the magnitude of the potential difference that occurs, varying from -7 to 125 V. The relationship between the studied electromagnetic properties (saturation magnetization, coercive force, Curie temperature) of the obtained samples and the precursor-earth potential difference arising during synthesis is shown. The Curie temperature values varied in the range of 38-79°C for samples obtained under the influence of an alternating electro-magnetic field, and 49-104°C in its absence.

Authors: Giao Nguyen Thanh , Thien Tran Tu
Published: December 2022

The characteristics of waste composition and community behavior are important data for making an appropriate domestic solid waste management plan. However, these data are lacking or not studied in Bac Lieu, especially in rural areas. Therefore, the study was conducted to determine the domestic waste composition and evaluate the factors related to the knowledge, attitude and practice (KAP) level of the community in domestic solid waste management in Phuoc Long district, Bac Lieu province, Vietnam. The results of domestic solid waste samples collected at households showed that the waste was composed of organic (73.8%), recyclables (15.7%), hazardous waste (0.7%), and others (9.9%). Plastic bags (42.7%) and papers (30.5%) were predominant in the recyclables. The interview of 150 households indicated that the majority of respondents had an average level of knowledge (46%), and attitude (49.3%). However, 46% of respondents had an inadequate level of practice. In addition, the study observed that respondents have a good level of knowledge and attitude that leads to good practice. The Chi-square test showed that the KAP level of the respondents is influenced by demographic factors including age, education, occupation and income (p<0.05). In which, education level and age were the significant influencing factors. The results indicated that education for improving the community’s knowledge and attitudes in domestic solid management should pay more attention on the population aged over 60 years and those with occupations belonging to agriculture and housework.

Investigating the Role of Salicylic Acid in Determining the Lifespan of Short-Lived and Long-Lived Flax Species and Lines
Authors: Kothari Sajani S. , Brown Jason C. L.
Published: December 2022

Introduction: Reactive oxygen species (ROS) accumulation has been related to aging in both plant and human physiology. Leaked electrons from the electron transport system (ETS) react with molecular oxygen producing ROS, such as hydrogen peroxide (H2O2) and superoxide anions. There are numerous antioxidative mechanisms present in plants that aid in redox balance, one of which is the mild uncoupling of mitochondria. Uncoupling agents, such as salicylic acid (SA), can abolish the connection between oxidation and phosphorylation allowing electron transport to take place without the need for parallel ATP synthesis. “Uncoupling to Survive” Hypothesis states that uncoupling activity should be greater in long-lived species since uncoupled mitochondria result in reduced ROS production thereby increasing lifespan. Since ROS accumulation has been linked to lifespan in the Oxidative Stress Theory of Aging, the idea that long-lived species should exhibit greater antioxidative capacity than short-lived species is the foundation upon which this hypothesis is established. We tested this hypothesis in various flax species and lines differing in lifespan.
Methods: Spectrophotometry was used to determine SA levels in plant tissue while respiration rates were measured using a dissolving oxygen electrode.
Results: The “Uncoupling to Survive” Hypothesis does not seem to hold for flax since long-lived and short-lived species did not exhibit significant differences in oxygen consumption rates that would indicate differences in the uncoupling activity of their mitochondria.
Discussion: However, early flowering lines exhibited lower levels of SA suggesting that flax plants do not require elevated SA expression to display the early flowering phenotype as seen in Arabidopsis species. In addition, SA significantly increased the oxygen consumption rates in wild-type and early flowering plants which further provides evidence for its role as an uncoupling agent.
Conclusion: Our findings add to our understanding of the many roles that SA plays in plant physiology. Advantages of SA are well established in the cosmetic and medical communities and investigating its effects on plants can be beneficial. We also looked at the "Uncoupling to Survive Hypothesis" in plants, which helped us get a better grasp of the antioxidant mechanisms that may eventually reduce oxidative stress and lead to senescence.

Medicinal plant Fagonia cretica L., is well known in traditional medicines for curing various complaints of human beings from ancient times and is locally known as Dhamasa. Previous many studies have reported the presence of many phytochemicals, antimicrobial, and antioxidant properties in the various parts of this plant. Therefore, here in this study, we have presented a comprehensive study on the presence of similar medicinal and chemical properties of Dhamsa found in Jamshoro District, Pakistan. For this study, extracts of the root, stem, leaf, and pod of the plant were prepared separately from three different solvents, water, ethanol, and methanol. Then the amount and presence of various phytochemicals, antimicrobial, antioxidant properties, and allelopathic effects were determined in all the extracts. The obtained results of this study confirm the presence of medicinal important phytochemicals in the plant extracts. The antimicrobial testing of this plant proved its highest activity against E. coli (16 ±1.4mm), Salmonella typhi (18±0.7mm), and Pseudomonas aeruginosa (15±1.4mm) in methanol, water, and ethanol extracts respectively. The presence of antioxidant activities was also observed in the ethanolic extract of the leaf at about 0.98 mg/ml. While this plant showed allelopathic effects on the growth of radish and spinach plants. So, we have concluded this study that Fagonia cretica L., collected from Jamshoro has the same or more important properties compared to the same plant from other regions, which proves the similar significant value of the Fagonia cretica plant of Jamshoro in various fields of medicinal sciences.

The study assessed the variabilities in climate and key factors of rice production in southeastern Nigeria. Trend analysis and spatial interpolation expressed the spatiotemporal variabilities in the climate and rice yield. Copies of the questionnaire were used to assess four hundred and eighty farm households from 12 local government areas. Other analyses included descriptive statistics, logistic regression, and Productivity Index. The farmers’ socioeconomic characteristics show that the majority (62% of them are young males aged between 30-39 years. Over 80% of them were married while about 72% has household sizes between 5-9 persons. A greater proportion (54%) of them generate between N240,000.00 (578 USD) to N480,000.00 (1156 USD) annually. About 96 % have a farming experience above 10 years, while 50% have basic education (primary education). Logistic regression shows that sex (0.02), category of the farmer (0.00), age (0.03) (0.00), educational qualification (0.02) (0.00), membership of cooperative society (0.00), extension workers’ visit (0.03) were the statistically significant determinants of rice productivity in the area. The area experiences significant rising temperatures and declining rainfall. This trend is more obvious in Ebonyi state.

In modern digital agricultural applications, automatic identification and diagnosis of plant diseases using artificial intelligence is becoming popular and widespread. Deep learning is a promising tool in pattern recognition and machine learning and it can be used to identify and classify diseases in paddy rice. In this study, 2 different paddy rice diseases, including rice blast and brown spot, were investigated in the district of İpsala in the province of Edirne between the 2020 and 2021 production seasons by collecting 1569 images. These diseases are very common and important in Edirne province and surrounding rice production areas. Therefore, practical methods are needed to identify and classify these two diseases. A Convolutional Neural Network (CNN) model was created by applying pre-processing techniques such as rescaling, rotation, and data augmentation to the paddy rice disease images. The classification model was created in Google Colab, which is a web-based Python editor using Tensorflow and Keras libraries. The CNN model was able to classify rice blast and brown spot diseases with high accuracy of 91.70%.

Abstract: Due to the fact that they can be preserved for extended periods of time and are utilized in virtually all cuisines, wheat and wheat products are the most popular grains to grow and produce. Beyond the current climate change impacts, closed national borders and growing limits for import-export products throughout the pandemic phase have caused governments to question their ability to produce enough food to meet their own needs in the short term. One of the objectives of this research is to determine what variables affect wheat self-sufficiency in Türkiye, which is one of the world's major wheat suppliers, and to develop recommendations for wheat production areas in the face of climate change's predicted impacts. With respect to Türkiye, wheat self-sufficiency data from the Turkish Statistical Institute (2000 to 2020) and regional climate change projections data from the General Directorate of Meteorology for the years 2050 and 2080 were used to identify the most significant variables, as well as the relationship between those variables and self-sufficiency. The findings indicate that wheat production is the most essential component in achieving wheat self-sufficiency and that climate change has a significant impact on wheat productivity and the areas where wheat is grown. Following this, the study concludes by detailing prospective wheat production regions in current great plain areas in the context of regional climate change projections, as well as critical policies for sustainable wheat cultivation.

Fluorescent pseudomonad is one of the biocontrol agents against plant pathogens. Various compounds reportedly can be produced by fluorescent pseudomonad, including chitinase, β-1,3-glucanase, HCN, siderophore, antibiotics, Indole Acetic Acid (IAA), phosphate solvent compounds, and 2,4-diacetylphloroglucinol (DAPG). In this study, it was identified and characterized six isolates of fluorescent pseudomonad (PfPj1, PfPj2, PfKd7, PfCas, PfCas3, and LAHp2). All isolates were isolated from the rhizosphere of various types of plants. The results showed that six isolates were identical to Pseudomonas aeruginosa (93-94%). All bacterial isolates tested were able to produce siderophore, HCN, and solubilize phosphates. The highest siderophore was produced by isolate PfPj2. Whereas isolate PfKd7 had the highest at HCN production and the ability to dissolve phosphates.

Published: December 2022

Traditional rice (Oryza sativa L.) landraces provide many essential genes for improving yield, disease resistance, abiotic stress tolerance, and other parameters for future rice breeding. This study aimed to analyze the genetic diversity and determine the phylogenetic position of the traditional rice landraces from the tidal swamp areas of South Kalimantan, Indonesia, compared to other rice germplasm, including wild relatives, obtained from the GenBank database, using a cpDNA-rbcL marker. In this case, six traditional rice landraces from this region were collected and analyzed molecularly using the rbcL marker and compared with 16 similar others and 25 wild relatives from the GenBank database. The genetic diversity of this germplasm was determined using the nucleotide diversity index (π), whereas the phylogenetic analysis by maximum likelihood with bootstrap for 1 000 replicates. The principal component analysis (PCA) was employed to confirm this grouping. Based on this marker, the traditional rice landraces have a genetic diversity of 0.38, lower than intra-species and inter-species levels, i.e., 0.44 and 0.83, respectively. The phylogenetic analysis shows that this germplasm has separated from most O. sativa rice cultivars and their wild relatives, except for the ‘GBVN’ and ‘NARC’ (comparison cultivars obtained from GenBank). This information has substantial implications for future rice breeding and conservation efforts, locally and globally.

The correlation of agromorphological traits can be useful for breeders in the selection of plant genotypes. In this study, the rosette period (days), days of maturity, plant height (cm), 1000-seed weight (g), and seed yield (kg ha–1) characteristics of 42 different Camelina genotypes that grown in Ankara (middle Anatolia) and Şanlıurfa (southeastern Anatolia), and their correlations with each other, were investigated. The accessions showed different results depending on the location in terms of the studied characters in both locations under rainfed conditions. The results showed that the highest seed yield was obtained from the PI 311735 accession (3151.8 kg ha–1) in Ankara and the PI 650142 accession (3056.0 kg ha–1) in Şanlıurfa. While the rosette period (days), days of maturity, plant height (cm), and 1000-seed weight (g), in Ankara were between 152.3 and 132.3 days, 274 and 247 days, 103.8 and 59.5 cm, and 1.50 and 0.84 g, while there were between 108.8 and 88.8 days, 202.1 and 180.1 days, 115.4 and 59.2 cm, and 1.40 and 0.50 g, in Şanlıurfa, respectively. Results showed significant differences among the genotypes in all of the studied parameters. Correlation analysis of the genotypes in both locations on the mentioned parameters was also performed. Since climate and environment affect each agromorphological parameter differently, it was observed that a genotypic correlation independent of the climate and environment could not be explained in the Camelina sativa genotypes.

Since Covid 19 was officially confirmed as a pandemic in early March 2020, the world has taken an initiative efficiency as one of their adjustment strategies towards business continuity. The Indonesian government then launched the Large-Scale Social Restrictions (PSBB) regulation.

Due to the implementation of this regulation, most of companies are forced to find a strategy to maintain the company's sustainability immediately. PSBB has had a major impact on many companies.  Several surviving companies have to apply work-from-home policy as well as several other attributes such as online meetings and the use of Kanban as their important medium to maintain productivity and performance.

This research attempts to analyze and tests the result of employee performance at PT. XYZ when working from home (WFH), using Kanban projects, online meetings and the impacts towards their performance. There are three independent variables here; work from home policy, implementation of Kanban project, and Online meeting. Meanwhile, the dependent variable is employee performance. The research instrument uses multiple linear regression methods. The result showed that there was an effect of Working-From-Home policy on performance which was 0.76, 0.05 for Kanban implementation and Online meeting was 0.06, where the simultaneous effect on employee performance was 78.39.
