A field experiment was conducted to evaluate the influence of foliar nutrition and growth regulators on the yield and economics of greengram during summer at Tamil Nadu Agricultural University farm, Coimbatore. The experiment was laid out in a randomized block design with ten treatments in which urea, DAP, salicylic acid and sodium molybdate were applied either alone or in combination and replicated thrice. The results revealed that foliar applications of 2% DAP+100 ppm salicylic acid + 0.05% sodium molybdate twice at vegetative and flowering stages of crop growth recorded better yield parameters and economics. However, all the yield attributing parameters recorded under 2% urea+100 ppm salicylic acid + 0.05% sodium molybdate twice were on par with 2% DAP+100 ppm salicylic acid + 0.05% sodium molybdate twice.

Heterosis and inbreeding depression in 10 crosses derived from 7 diverse parents and genetic variability studies in safflower was carried out during rabi 2009-10. The experimental material comprising of 20 populations and 7 parents for eight different quantitative characters revealed considerable amount of genetic variation for all the characters studied. Most of the characters were less influenced by the environment as minor differences were recorded between genotypic and phenotypic coefficients of variation. High heritability with high genetic advance was observed for number of capsules per plant, number of seeds per capitulum, test weight and seed yield which might be due to additive gene effects. Heterosis and inbreeding depression was observed positive in direction for most of the characters studied. Maximum heterosis was recorded for number of seeds per capitulum followed by number of capitula per plant and seed yield.

Sea ice age is a proxy for thickness, which can be obtained through the use of satellite data. The paper presents the results of comparison of CryoSat-2, SMOS and CryoSat-2 & SMOS fusion data with detailed ice charts (October–April, 2010–2018). The AARI ice charts were chosen as references for comparison because they integrate knowledge and data from various sources, including expert analysis of operational satellite information, in-situ measurements at coastal stations, data on ice conditions from ships of the Northern Sea Route (NSR). The division of satellite data elements into classes (stages of development) was performed according to the maximum likelihood classifier. The recognition result for each stage of development was evaluated by means of three criteria, in accordance with the class value ofMode,MedianandMean. The effectiveness of satellite data in determining the Kara Sea ice thickness varies depending on the sea ice stage of development and winter season time. Four stages of development (old ice, thick first-year ice, medium first-year ice, nilas) showed the best recognition results. Although the CryoSat-2 mission was designed primarily to detect climate-dependent variations of the thickness of floating ice, in terms of statistical recognition of the Kara Sea ice stages of development, CryoSat-2 data can also be used to retrieve the thickness of thick first-year ice (January–April) and the thickness of medium first-year ice (January–February). For the remaining stages within the study area, the altimetry method shows a significant uncertainty, which can be resolved for nilas, thin first-year ice and medium first-year ice (March) by using SMOS data and CryoSat-2 & SMOS fusion data. In general, altimetric data, radiometric data and combination thereof can be applied in the complex analysis of all available information to ensure hydrometeorological and navigation support. Also, it is proposed to use the data of the ICESat-2 laser altimeter and to make a general comparison with in-situ measurements.

The History of Philosophy and the Problem of Internal Continuity in National Philosophy
Authors:   Hryhoriy Skovoroda Institute of Philosophy of the National Academy of Sciences of Ukraine, Yosypenko Serhii
Published: May 2023

The problem of internal continuity in national philosophy is one of the most popular topoi in thinking about the identity and originality of national philosophical schools in East-Central Europe. This article looks at the role that history of philosophy (as a discipline and field of scholarly inquiry) might play in establishing and ensuring internal continuity in national philosophical traditions. In particular, the early twentieth century debate between Polish philosophers Henryk Struwe (1840–1912) and Kazimierz Twardowski (1866– 1938), emphasized a self-aware national reception of world philosophy, and the importance of addressing one’s own predecessors in national philosophy, as key factors in ensuring internal continuity. This article offers an analysis of the modern-day perception of this discussion, and the principles it offers, by Ukrainian philosophers. It also looks into the productivity of these factors, and the level to which they’re assimilated and used by Ukrainian philosophers. Acknowledging that the history of Ukrainian philosophy as a discipline and field of scholarly research in today’s Ukraine has turned into a sort of historical consciousness of Ukrainian philosophy, and leaning on the work of Vilen Horskyi (1931–2007), the author analyzes the conditions in which this discipline might become a factor in moulding a Ukrainian national tradition.

Thermo-hydrodynamic Analysis of Misaligned Journal Bearing Considering Surface Roughness and Non-Newtonian Effects
Authors: Abass Basim Ajeel , Kadhim Mustafa Mohammed
Published: May 2023

This paper presents a numerical simulation for the combined effect of surface roughness and non-Newtonian behavior of the lubricant on the performance of misaligned journal bearing. The modified Reynolds equation to include the effect of non-Newtonian lubricant and bearing surface roughness has been formulated. The model accounts for the lubricant viscosity dependence on temperature and shear rate. In order to make a complete thermo-hydrodynamic analysis (THD) of rough surface misaligned journal bearing lubricated with non-Newtonian lubricant, the modified Reynolds equation coupled with the energy, heat conduction equations, the equation related the viscosity and temperature with appropriate boundary conditions have been solved simultaneously. The performance characteristics of the bearing were presented with different roughness parameter for the pressure, temperature, load carrying capacity, misalignment moment and friction force. The computer program prepared to solve the governing equations of the problem has been verified by comparing the results obtained through this work with that published by different workers. It has been foundthat the results are in a good agreement .The results obtained in the present work showed that the surface roughness characteristics of opposing surfaces and its orientation play an important role in affecting the performance parameters of the bearing. It has been shown that the load in rough aligned journal bearing is higher than that in rough misaligned journal bearing for all surface roughness patterns (γ). An increase in load has been calculated and found to be 29.5% for the bearing with moving roughness while it becomes32% for the bearing with stationary roughness.
Neuroimaging workflows in the cloud
Authors: Madhyastha Tara
Published: May 2023

Analysis of large neuroimaging datasets requires scalable computing power and storage, plus methods for secure collaboration and for reproducibility. The application of cloud computing can address many of these requirements, providing a very flexible model that is generally far less expensive than a lab trying to purchase the most computer equipment they would ever need. This chapter describes how researchers can change the way that they traditionally run neuroimaging workflows in order to leverage cloud-computing capabilities. It describes various considerations and options related to cloud-based neuroimaging analyses, including cost models and architectures. Next, using data from the AOMIC-PIOP2 project hosted on OpenNEURO, it shows how to use NextFlow to create a very simple skull stripping and tissue segmentation workflow using FSL’s bet and fast programs installed on a local computer. Nextflow allows scalability from a laptop to a cluster to cloud-native services with no code changes.
Wigner's Puzzle on Applicability of Mathematics: On What Table to Assemble It?
Authors: Barboianu Catalin
Published: May 2023

Attempts at solving what has been labeled as Eugene Wigner’s puzzle of applicability of mathematics are still far from arriving at an acceptable solution. The accounts developed to explain the “miracle” of applied mathematics vary in nature, foundation, and solution, from denying the existence of a genuine problem to designing structural theories based on mathematical formalism. Despite this variation, all investigations treated the problem in a unitary way with respect to the target, pointing to one or two ‘why’ or ‘how’ questions to be answered. In this paper, I argue that two analyses, a semantic analysis ab initio and a metatheoretical analysis starting from the types of unreasonableness involved in this problem, will establish the interdisciplinary character of the problem and reveal many more targets, which may be addressed with different methodologies. In order to address objectively the philosophical problem of applicability of mathematics, a foundational revision of the problem is needed.
A Tale of Two Tweets: What Factors Predict Forgiveness of Past Transgressions on Social Media?
Authors: Dawson Andrew , Wilson Anne E
Published: May 2023

As more of our lives take place online, it is increasingly common for public figures to have their current image tarnished by their mistakes and transgressions in what is often the distant past. Three experiments (N = 2,296) found that judgements of a public figure who tweeted racist statements in the past were less harsh when more time had passed and when the public figure was younger at the time of the tweet. However, politics also played a powerful role. Independent of time and age, liberals allowed less possibility of redemption for anti-Black tweets, while conservatives were less forgiving for anti-White tweets. Such partisan differences extended not only to moral judgements of the individual, but also general moral principles and participants’ subjective perceptions of the situation itself, including subjective temporal distance from the tweet, the subjective age of the public figure, and the current relevance of the past statements.
Reduction of aversive learning rates in Pavlovian conditioning by angiotensin II antagonist losartan: a randomised controlled trial
Authors: Zika Ondrej , Appel Judith Elisabeth , Klinge Corinna , Shkreli Lorika , Browning Michael , Wiech Katja , Reinecke Andrea
Published: May 2023

Background: Angiotensin receptor blockade (ARB) has been linked to aspects of aversive learning and memory formation, and to the prevention of post-traumatic stress disorder symptom development. Methods: We investigate the influence of the ARB losartan on aversive Pavlovian conditioning using a probabilistic learning paradigm. In a double-blind, randomised placebo-controlled design, we tested 45 (18 female) healthy volunteers during a Baseline session, after application of losartan or placebo (Drug session) and during a Follow-up session. On each session, participants engaged in a task where they had to predict the probability of an electrical stimulation on every trial while the true shock contingencies repeatedly switched between phases of high and low shock threat. Computational reinforcement learning models were used to investigate learning dynamics. Results: Acute administration of losartan significantly reduced participants’ adjustment during both low-to-high and high-to-low threat changes. This was driven by reduced aversive learning rates in the losartan group on the drug session compared to baseline. The 50mg drug dose did not induce reduction of blood pressure or change in reaction times, ruling out general reduction in attention and engagement. Decreased adjustment of aversive expectations was maintained on a follow up session 24hrs later.Conclusions: This study shows that losartan acutely reduces Pavlovian learning in aversive environments. Such decreased learning may explain a previously reported preventive role of ARB in the development of anxiety symptoms.
Call to Action: Strategic Spatial Intervention Program (SSIP) for Improving the Spatial Reasoning and Navigational Skills of Older Adults
Authors: Zhong Jimmy Y.
Published: May 2023

Aging is a global phenomenon, with the world's population getting older as a whole. According to the World Health Organization (WHO), the number of people aged 60 years and older is expected to double by 2050, and by 2100, it is projected to triple (WHO, 2022). This trend is also reflected in the demographics of Singapore. Which has seen a steady increase in the proportion of older adults in its population over the past few decades. If this aging trend continues, a quarter of Singapore citizens is expected to be 65 years and older by the year 2050 (Malhotra et al., 2019). A major inconvenience that comes with normal biological aging relates to the noticeable declines in spatial navigation in the general subpopulation of older adults aged 60 years and older. Spatial navigation, by definition, refers to one’s innate ability to navigate and find destinations in his/her everyday physical environments. Over the past decade, a series of important research studies by Zhong (me) and colleagues provided some rigorous and reliable findings showing that spatial navigation abilities decline with increasing age, impairing cognitive functions that are crucial for daily living, such as attention, executive functioning, fluid intelligence, long-term and working memories (Mollusky…Zhong, Magnusson, 2023; Reynolds, Zhong, et al., 2019; Zhong et al., 2017; Zhong & Moffat, 2016, 2018). For many years, I have stressed the importance of understanding the neurocognitive mechanisms subserving these age-related declines in spatial navigation out of my personal convictions that such an understanding can engender significant applied implications for older adults' well-being and quality of life (Mollusky et al., 2023; Zhong, 2022; Zhong & Moffat, 2018). Thence, in this proposal, I argue for the urgency of designing strategic training or intervention methods to attenuate declines in spatial navigation among the elderly, an effort which I hope can bring about significant improvements in older adults' overall independence of movement and psychological well-being (see also Zhong, 2022, for a detailed discussion).

BackgroundRecovery Colleges (RCs) support the recovery of individuals who have mental health issues, using the principles of coproduction and adult learning. There has been little international research on RCs and none investigating costs, staffing, or fidelity to these and other principles. We aimed to characterise RCs internationally. MethodsWe conducted an observational study integrating two equivalent cross-sectional surveys, one conducted within England in 2021 and one in all other countries in 2022. We included all RCs meeting recovery orientation, coproduction and adult learning criteria. Managers completed a survey capturing organisational and student characteristics, fidelity and budget. RCs were grouped by country and continent to allow for regression models exploring continental differences in fidelity.OutcomesWe identified 221 RCs operating across 28 countries, spanning five continents. Overall, 174 (79%) RCs participated in the survey. Most scored high on fidelity. Compared with England, RCs in Asia scored lower on overall fidelity, ‘coproduction’ and ‘tailored to the student’. Annual budgets in the 133 (60%) colleges providing economic data were €0-2,550,000, varying extensively within and between continents. Among the RCs who provided data, annual budgets totalled €30m, providing 19,864 courses for 55,161 students. InterpretationRCs exist in many countries. There is an international consensus on key operating principles, especially equality and a commitment to recovery, and most RCs achieve moderate to high fidelity, irrespective of the income band of their country. Cultural differences need to be considered in assessing coproduction and approaches to individualising support.

The purpose of the study is to improve the process of roof management in the face, by upgrading the power element of the mechanized fastening. Scientific novelty and practical significance. Existing research on this topic, related to improving the performance of the fastener, refers to the fact that the normal operation of mechanized fastening, under given conditions, depends on the parameters of the array, the correct choice of mechanized fastening for this face and measures to adapt mechanized fastening to load conditions. However, in all modern research there is no single approach and systematicity, which is proved in particular by the impossibility of widespread use of criteria for assessing interaction, and a large number of theories of stress-strain state of the array, which are valid within certain limits. Therefore, this work, devoted to increasing the service life of mechanized fasteners in the Donbass, by reducing the critical loads in the main fastening units, is relevant because it solves an important scientific and technical problem of analysis and adaptation of mechanized fastening to load conditions, due to statistical analysis of fastening operation in given conditions, modeling of mechanized fastening and load conditions in SolidWorks, calculations for load and fatigue under the action of variable load on fastening model, for rigid rack design, and hydraulic resistance, development of fundamentally new structure of power element of mechanized fastening for given conditions in SolidWorks software environment, methods of modeling load conditions in SolidWorks software environment. Method. Statistical analysis of malfunctions and analytical calculations of parameters are used. Results of the research. Based on the collected data on the operation of mechanized complexes we identified and characterized the shortcomings in the work and the reason for their occurrence, determined the algorithm for pressure jumps at dynamic loads and the criteria of the required initial spacing, made a histogram of the final pressure in hydraulic racks at dynamic load.

Purpose to work: to study the dynamic process of drilling with step drills in difficult-to-machine body parts of complex shape. The effective ways to improve the processing are suggested. Methodology: to create a mathematical model of drilling a hole in the part by the finite element method and to analyze the machining process by varying the different parameters of the cutting modes. Results: the analysis of the factors influencing cutting process is done. The advantages of using a step drill when machining holes in complex, difficult-to-machine parts are substantiated. A mathematical model of the finite element drilling process has been developed. The dynamic drilling process according to different variation of cutting mode parameters is investigated and the data on tool movement and stresses arising in the process of work piece processing are obtained. The results obtained indicate that as the cutting speed increases due to the increase in forces, the forces acting on the drill in the axial direction increase. Thus, due to the properties of the feed drive, increasing the feed rate of the tool, it also increases the cutting forces, as well as the thermodynamic loading of the drill, which reduces its stability. The locations of the largest stresses on the cutting edges of the drill have been identified, which can affect the quality of the resulting hole, the strength and stability of the drill. Scientific novelty: the mathematical model of processing of a difficult detail by a step drill is developed. Practical significance: recommendations on the use of step drills and the possibility of increasing the stability of the tool and the accuracy of processing.
