Published: September 2022

Inevitable mistuning in cyclic bladed disk structures would cause vibration amplification phenomena that seriously reduce the reliability of the bladed disk. The ability to accurately and quickly predict the dynamic responses is critical to investigating the dynamic behavior of the mistuned system. However, it is still challenging because the mistuned responses are extremely sensitive to the random mistuning parameters. In this work, a novel mistuned system deep neural network model (MS-DNN) is presented to predict the dynamic responses of mistuned bladed disks through the mistuning parameters for both the lumped parameter model and the large-scale finite element (FE) model, which decouples the vibration equations of the mistuned system and uses a neural network to replace the coupling process. MS-DNN is divided into two levels, namely, the blade and the disk. The blade-level neural networks are used for forward and backward propagation of mistuning parameters in the different blades, and the disk-level neural network is used to replace the physical coupling process in the disk of multiple mistuning parameters from individual blades, with data transmission between the neural networks via blade–disk boundary nodes. The expected physical response of the blade tip is predicted through MS-DNN. All neural networks in MS-DNN show high prediction accuracy on both training sets and unknown test sets. For the FE model of the industrial bladed disk, the effect of the number of boundary nodes selected as the data interface between neural networks on the prediction accuracy is also investigated. The results show that, for unknown test data, the predicted response has an [Formula: see text] value of 0.998 versus the actual response with an amplification factor error of less than 0.388%.

Flatfoot is a foot deformity characterized by a collapsed medial arch, plantar flexion and medial rotation of the talus, eversion of the calcaneus, and forefoot abduction. The flatfoot prevalence and causes are not well known despite its correlation with multiple factors. This study aimed to systematically review all studies that estimated the flatfoot prevalence among Saudi population and list the associated factors. Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines and Joanna Briggs Institute reviewer’s manual were followed to perform this systematic review. Data collection was through several databases using terms including prevalence, Saudi, and flatfoot with their synonyms. The inclusion criteria were both adults and children’s studies that were carried out in Saudi Arabia (Saudi and non-Saudi), with the exclusion of secondary flatfoot (due to traumatic or pathological causes) studies. A total of 361 published studies before July 2021 which involved 6190 participants were reviewed, and only six studies were included in the study. The participants’ age ranged from 4.2 ± 3.6 to 37 ± 11.26 years. There was male predominance, with body mass index (BMI), age, and gender being common factors studied in the articles. Flatfoot prevalence in Saudi Arabia differed according to multiple factors as reported by different authors. This review revealed a wide range of flatfoot prevalence among the Saudi population. Most of the included studies reported that BMI, age, gender, residence, family history of flatfoot, footwear type during childhood, hypermobility, functional mobility, balance, and flexibility of the whole body had a significant impact on flatfoot prevalence.
AROPS: A Framework of Automated Reaction Optimization with Parallelized Scheduling

Published: September 2022

With the development of automated experimental platforms and optimization algorithms, chemists can easily optimize chemical reactions in an automated and high-throughput fashion. However, the modules in existing automated experimental platforms are operated in a predefined way without orchestrating with the optimization algorithm, thus leaving room for further efficiency improvement. Here, we introduced a framework of automated reaction optimization with parallelized scheduling (AROPS) to realize the integration of optimization algorithm and module scheduling. AROPS relies on a customized Bayesian optimizer to solve multi-reactor/analyzer reaction optimization problems with three different scheduling modes to arrange tasks for various experimental modules. In addition, a mechanism based on probability of improvement (PI) for discarding unpromising on-going experiments was developed to facilitate freeing-up valuable experimental resources in parallelized optimization. We tested the performance of AROPS using a hardware emulator on three typical benchmark reactions encountered in organic synthesis, illustrating that AROPS can trade off optimization time and cost according to the chemists’ preference.

Published: September 2022

To figure out the reason for the drawback of the SWIFT waveform and realize the high-resolution ion isolation on the miniaturized linear ion trap mass spectrometer, we studied the efficiency that ions can be excited under different excitation periods and amplitudes at different frequencies and compared the overlap rates of the effective excitation bandwidths of the adjacent ions. According to this, we purposed a new coarse-to-fine isolation waveform named SWIFTSIN. By superposing one or more sinusoidal waveforms on the SWIFT waveform and modulating the phases of the superposed sinusoidal waveforms, the generated SWIFTSIN waveform achieved unit mass isolation on the miniaturized linear ion trap mass spectrometer without reducing the intensity of the target ion. The isolation ability of the SWIFTSIN waveform was verified by isolating a single isotope peak in the mixed samples.

Published: September 2022

Infectious microbial diseases can easily be transferred from person to person in the air or via high contact surfaces. As a result, researchers must aspire to create materials that can be implemented in surface contact applications to disrupt pathogen growth and transmission. Silver (Ag) is known to possess antimicrobial activity and has been used in the past in various pharmaceutical applications. Herein, we examine the antimicrobial properties of polyacrylonitrile (PAN) nanofibers coated with different concentrations of silver nanoparticles (AgNPs). Polyacrylonitrile (PAN) was homogenized with varied weight concentrations of silver nitrate (AgNO3) in N,N-Dimethylformamide (DMF) solution, a common organic solvent that serves as both an electrospinning solvent and as a reducing agent that forms AgNPs. The subsequent colloids were electrospun into nanofibers, which were then characterized via various analysis techniques, including Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-Ray (EDX) Analysis, Dynamic Light Scattering (DLS), and X-Ray Photoelectron Spectroscopy (XPS). 10 microbes, including 7 strains of Gram-positive bacteria, 2 strains of Gram-negative bacteria, and Candida albicans were incubated with cutouts of various PAN-AgNP nanocomposites using disk diffusion methods to test for the nanocomposites’ antimicrobial efficiency. We report that PAN-AgNP nanocomposites retain a certain degree of antimicrobial longevity; samples stored for approximately 90 days demonstrate similar antimicrobial activity against Escherichia coli (E. coli) and Lactobacillus crispatus (L. crispatus) when compared to their newly electrospun counterparts. Moreover, our results indicate that PAN-AgNP nanocomposites successfully display antimicrobial activity against various bacteria and fungi strains regardless of their resistance to conventional antibiotics. Our study demonstrates that PAN-AgNP nanocomposites can potentially be applied to surfaces at risk of contracting microbial infections.
Variable Kinetic Isotope Effect Reveals Multi-step Pathway for Protonolysis of a Pt–Me Bond

Published: September 2022

The reaction of (cod)PtMe2 (cod = 1,5-cyclooctadiene) with trifluoroacetic acid (TFAH) to release methane is an important system because it represents the microscopic reverse of desirable methane activation, and because it has an unusually large kinetic isotope effect (KIE) that has been tentatively attributed to proton tunneling. A detailed kinetic and mechanistic inves-tigation of this system was conducted using stopped-flow and traditional time-dependent UV-vis spectroscopy, supported by NMR and DFT studies. Consistently large KIE values (~14) in line with previous reports were obtained over a large range of reactant concentrations (0.1 – 1.6 mM (cod)PtMe2 and 3.2 mM to 6.0 M acid). At lower concentrations of acid, the KIE decreased significantly (KIE = ~6 for 0.1 mM (cod)PtMe2 and 0.2 mM acid). This concentration-dependent KIE suggests a multi-step reaction mechanism, eliminating the need to invoke proton tunneling. The reaction exhibits first-order dependence on (cod)PtMe2 and approximately second-order dependence on acid, with at least 2 equivalents of acid required for complete conversion. Overall, the kinetic data indicate a multi-molecular, multi-step reaction mechanism for the protonolysis of (cod)PtMe2, thus ruling out the previously accepted bimolecular single-step mechanism. A mechanistic alternative consistent with the kinetic data is proposed, in which sequential oxidative addition and reductive elimination occur, and the second equivalent of acid serves to stabilize trifluoroacetate anion in solution.

Over recent decades, the pipeline of antibiotics acting against Gram-negative bacteria is running dry, as most discovered candidate antibiotics suffer from insufficient potency, pharmacokinetic properties, or toxicity. The darobactins, a promising new small peptide class of drug candidates, bind to novel antibiotic target BamA, an outer membrane protein. Previously, we reported that biosynthetic engineering in a heterologous host generated non-natural darobactins with significantly enhanced antibacterial activity. Here we utilise an optimised purification procedure and present cryo-EM structures of the Bam-complex with darobactin 9 (D9), which served as a blueprint to further the biotechnological generation of twenty novel darobactins including halogenated analogues. The newly engineered darobactin 22 binds more tightly to BamA and outperforms the favorable activity profile of D9 against clinically relevant pathogens such as carbapenem-resistant Acinetobacter baumannii up to 32-fold, while toxic effects were not observed in human cells and zebrafish embryos up to 500 µg/mL.

Background. Due to the increasing prevalence of abnormal uterine bleeding (AUB) among obese adolescent girls, a factorial analysis of the probable causes of this pathology is highly relevant.
Aim. To analyze and characterize clinical, hormonal, metabolic features and parameters relevant to the assessment of ovarian reserve in adolescent girls with obesity and AUB.
Materials and methods. The study included 2 groups of obese adolescent girls who have passed at least 12 months from the start of menarche, who do not have endocrine and severe somatic diseases; main group: adolescent girls with obesity (SDS BMI more than 2) and abnormal uterine bleeding of the type of opso-oligomenorrhea and secondary amenorrhea; comparison group: adolescent girls with obesity (SDS BMI more than 2) and absence of menstrual cycle disorders.
Results. Among adolescent girls without AUB, severe forms of obesity (34 art.) were more common than in the group with AUB. According to the metabolic status, plasma triglyceride and cholesterol levels were significantly higher in the AUB group compared with adolescent girls without menstrual disorders (p=0.035 and 0.043, respectively).When assessing carbohydrate metabolism, no significant differences between the groups were obtained (p=1.000). According to the results of the study of the hormonal status, no significant differences between the groups were obtained. The hirsute number had no significant differences in the groups. The correlation analysis revealed a positive correlation between the severity of obesity with the HOMA index (p=0.034), a positive correlation of the prolactin level with the hirsute number (p=0.021) and estradiol (p=0.04). The median level of anti-muller hormone in the group with AUB was significantly higher compared to the group without AUB (6.13 ng/ml vs 2.09 ng/ml, p0.05). When analyzing the follicular apparatus of the ovaries, it was found that the median volume of both the right and left ovaries in girls of group 1 with obesity and the AUB was larger than in the comparison group. The median number of follicles in the section in group 1 also indicated a greater number of them compared to the comparison group.
Conclusion. In the studied groups, girls with a more severe degree of obesity were more often associated with the absence of AUB, but metabolic disorders were more common in the group of girls with AUB. When assessing the ovarian reserve, a direct correlation was obtained between the level of anti-muller hormone and the number of antral follicles in the ovary.

Published: September 2022

Coffee is a major plantation cash crop of hills of Nepal. Gulmi is one of the popular districts for coffee production and export in Nepal. This research is an attempt to assess the production potentiality and profitability of coffee in Gulmi district. This study was carried out in four rural municipalities of Gulmi district namely Ruru rural municipality, Dhurkot rural municipality, Satyawoti rural municipality and Musikot municipality. A total of 100 samples (25 from each rural municipality) were selected using simple random sampling technique. Face to face (FtF) interview method was used to collect primary data using pretested semi-structured questionnaire. The economic indicators of coffee production like gross revenue, gross margin, benefit-cost ratio (BCR) and profitability index (PI) were calculated. BCR and PI were found to be 2.84± 0.59 and 2.50± 1.25, respectively. Gross margin per ropani was calculated to be NRs. 15675.29 ± 7189.72. The contribution of coffee in total household income was 12% in Gulmi showing it to be one of the major influencing commodities. The major production problem was found to be insect attack in the district while the major marketing problem was the low market price. The insights of this research were that coffee has the potentiality to uplift the rural income of Gulmi but at the same time there were poor extension services for coffee growers such that farmers had shown dissatisfaction towards coffee enterprise. Therefore, effective package of production and value chain monitoring should be introduced by the Nepal government in order to address the production and marketing constraints of coffee producers.

The study was conducted at the Postharvest and plant Biotechnology laboratory, Department of Horticulture, Patuakhali Science and Technology University, Patuakhali, Bangladesh during the period from January to July 2017 to isolate, screening and molecular identification of antagonistic bacteria against anthracnose of mango. All treatments were arranged in a completely randomized design (CRD) with replications and repeated twice. Epiphytic bacteria, isolated from leaf and fruit surfaces of mango, were tested as biocontrol agent against anthracnose disease caused by Colletotrichum gloeosporioides wherein 20 strains were confirmed as antagonistic. Molecular characterization of the three potential strains of bacteria were done by the amplification of 16S rDNA gene following the extraction of genomic DNA, polymerase chain reaction (PCR) amplification, gel electrophoresis and gel documentation. The PCR amplified products and the genomic DNA samples were sent to the Macrogen Company through Sunchon National University, Seoul, South Korea for molecular identification by sequence analysis. Among the 20 antagonistic bacteria screened in vitro by dual and concomitant tests, two isolates, namely GB6 (PSTU-Hort-8), and GB19 (PSTU-Hort-14) were recognized as antagonistics to the test fungus. Using the molecular identification systems, isolated bacterial strains PSTU-Hort-8 was identified as B. subtilis with National Center for Biotechnology Information (NCBI) accession numbers MW659188; on the other hand, strain PSTU-Hort-14 was identified as Stenotrophomonas rhizophila with NCBI accession number MW659190.

Published: September 2022

Purple rice has become a fascinating source of nutritional value among healthy cereal grains. A field experiment was conducted at Bangladesh Agricultural University during the Rabi season (February to May) of 2021 to evaluate the effect of number of seedlings/hill on growth, yield attributes and yield of Purple rice. Three seedling densities, viz. 1, 2 and 3 seedlings/hill, and three rice cultivars, viz. Purple rice, Pahari rice and a check BRRI dhan67 were experimental treatments and the experiment was laid out in a split-plot design with three replications. Results revealed that seedling number/hill had significant effects on the growth, yield and yield attributes of rice cultivars. The tallest plant (136.31 cm) was observed from the transplanting of 1 seedling/hill followed by 2 seedlings/hill (133.35 cm) in Pahari rice. The maximum values of the number of effective tillers (13.47; Purple rice), flag leaf length and width (41.36 and 1.24 cm; Pahari rice) were recorded from the treatment 2 seedlings/hill. The longest panicle (26.58 cm; Pahari rice) was observed in 1 seedling/hill, statistically, a similar value was found with 2 seedlings/hill (24.44 cm). Among rice cultivars, BRRI dhan67 produced the heaviest grains (1000-seed weight 23.96 g) with 2 seedlings/hill and maximum grain yield (6.35 t/ha) with 1 seedling/hill. Single seedling/hill was found to be the best management practice to get a higher yield per unit area for Purple rice and other rice cultivars also.

Tripolar fuzzy sets are a concept that deals with tripolar information. This idea is a generalization of bipolar and intuitionistic fuzzy sets. In this paper, the notions of tripolar fuzzy pure ideals in ordered semigroups are introduced, and some algebraic properties of tripolar fuzzy pure ideals are studied. We obtain some characterizations of weakly regular ordered semigroups in terms of tripolar fuzzy pure ideals. Finally, we introduce the concepts of tripolar weakly pure ideals and prove that the tripolar fuzzy ideals are tripolar weakly pure ideals if such tripolar fuzzy ideals satisfy the idempotent property.

The green seaweed Caulerpa can be found in almost every coastal area of Indonesia, and it is one of the seaweeds with immense potential to be developed in the future. The chemical factors, especially water nutrients (nitrate, nitrite, phosphate, and ammonia), play an essential role in the distribution and diversity of seaweed. This study aimed to identify the abundance, ecological index, and relationship between the water column nutrients concentration and the biodiversity of Caulerpa from three different locations (Bintan Island, Jepara, and Osi Island). There were 12 points of observation at each site. The result showed a correlation between the nutrient levels and the abundance and diversity of Caulerpa in three locations. The nitrate, ammonia, and DIN:P ratio values were significantly different between areas. In contrast, there were insignificant differences in nitrite and phosphate concentrations between sites. The highest nitrate and phosphate concentrations were observed on Osi Island. The nitrite and ammonia values were identical for the condition on Bintan Island. The nitrate value was the main characteristic that distinguished the water nutrient at all sites. The Caulerpa species found in this research were Caulerpa racemosa, Caulerpa lentilifera, Caulerpa serrulata, Caulerpa sertularoides, and Caulerpa cupresoides. The nitrate and phosphate values influenced the growth factor of the green seaweed Caulerpa lentilifera. Caulerpa racemosa and Caulerpa serrulata, on the other hand, grew in response to ammonia levels. Caulerpa cupresoides diversity and abundance were impacted by the nitrite value. The results of the canonical correspondence analysis revealed that nitrate, phosphate, and ammonia were the most important factors influencing Caulerpa distribution in three locations.

The accuracy of calculation methods for determining the evapotranspiration (ET) of corn for grain under drip irrigation in the steppe of Ukraine was established. A comprehensive assessment of calculation methods for soil optimal water regime formation during different growth phases of maize plants was carried out. The accuracy of the estimated value of evapotranspiration was determined by the mean absolute percentage error (MAPE). It has been proven that the use of calculation methods without taking into account the climatic conditions of Southern Ukraine leads to a significant error in determining the actual evapotranspiration. By the Penman-Monteith method, the MAPE of 16.3-26.9% corresponds to the good and satisfactory accuracy of the chosen calculation model. Using the methods of A.M. and S.M. Alpatyev as well as D.A. Stoyko the MAPE increased to 22.2-39.7% and 20.8-29.1%, respectively, which proved their satisfactory accuracy. The calculation method of M.M. Ivanov ensured the MAPE of 48,7-76,8%; that is unsatisfactory calculation accuracy. Adapted crop coefficients Kc for the conditions of the South of Ukraine increased the accuracy of calculating ET by the Penman-Monteith method by an average of 2,2 times, D.A. Shtoyko and A.M. and S.M. Alpatiev by 1,9 and 2,2 times, and M.M. Ivanov by 4,4 times. An analysis of the MAPE using various calculation methods for determining the evapotranspiration of corn for grain under drip irrigation showed that the Penman-Monteith method provides the smallest error (MAPE = 9.1%), which corresponds to high prediction accuracy. In a wet year, the accuracy of ET determination decreases by all methods, which indicates an increase in the MAPE: by Penman-Monteith and D.A. Shtoyko - up to 11.9% and 18.7%, respectively, and the determination accuracy decreases to category “good”. When calculating using the methods of A.M. and S.M. Alpatiev and M.M. Ivanov the MAPE increased to 23,3% and 21,5%, respectively, and the accuracy of ET determination was satisfactory.
Reforming Public Administration in South Africa: A Path to Professionalisation
Authors: Klaaren Jonathan , Brunette Ryan , Belvedere Florencia
Published: September 2022

This short book analyses three distinct and key features of the state: the system of appointment and removal in the public service and municipalities, high-level appointments and removals within the criminal justice sector, and public procurement. A state’s politics and its capacities are constituted in important ways by how it fills its public administrative offices (including its prosecution service) and purchases its necessities. The book, considering outcomes in South Africa, advocates for specific reforms in each area. It argues that the timely consideration and adoption of reforms along these lines is an urgent task. With that in mind, the book has been written chiefly for two audiences: both for activists keen to build a state which can play its role in advancing the progressive transformation of South African society, and for scholars who are interested in understanding the character and possibilities of the evolving South African public administration.

New methods, persistent issues, and one solution: Gene-environment interaction studies of childhood cognitive development
Authors: von Stumm Sophie , Lyon Kieran , Nancarrow Alexandra Failor
Published: September 2022

Children’s differences in cognitive development stem from the complex interplay of genetic and environmental factors. Identifying gene-environment interactions in cognitive development is key for effectively targeting interventions that improve children’s life chances. The advent of polygenic scores, which aggregate DNA variants to index a person’s genetic propensities for phenotypic development, has created unprecedented opportunities for pinpointing gene-environment interactions. Yet, the issue of statistical power -- the probability of detecting a true effect – prevails, and no replicable gene-environment interactions in child cognitive development have been reported. The solution is simple and daunting at the same time: Gathering larger samples will be the key to ushering a new era of replicable gene-environment interaction findings.
