Assessment of Different Production Systems for Macro and Micronutrient Concentration in Selected kharif Crops in Low Hills of Himachal Pradesh

A field experiment was conducted to assess the effect of different crop production systems on major kharif crops at Choudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya, Hill Agriculture Research and Extension Center, Dhualakuan (Himachal Pradesh) India. The experiment comprised of fifteen treatments involving three crop production systems (organic, natural and conventional) in subplot with five crops (maize, okra, sesame, black gram and rice) in the main plot replicated thrice in split-plot design during kharif season (July-October) of 2020. Among different production systems, macronutrient contents were found highest under conventional system followed by organic system and lowest in Subhas Palekar Natural Farming system. Sulfur and micronutrient content was recorded highest in organic farming system followed by Subhas Palekar Natural Farming system and lowest in conventional system. Among crops, black gram and sesame grain macro and micro nutrient content was found to be highest and lowest in okra among all crops.

Impacts of feeding milk replacer supplemented with increasing concentrations of choline on feed intake, growth, and scouring incidence for 7 weeks preweaning and 1-week postweaning.

The objective of this study was to evaluate the effect of increasing choline supplementation on the intake of milk replacer (MR) and calf starter (CS), growth performance, and fecal scores of calves over 8 weeks. One hundred calves from commercial herds were transported to the University of Minnesota Southern Research and Outreach Center (SROC) calf facility randomized to one of 4 treatments differing in choline supplementation within MR including: 0 (C0; n = 24), 700 (C700; n = 26), 1400 (C1400; n = 25), and 2100 mg/kg choline (C2100; n = 25). MR contained a basal concentration of 1650 mg/kg MR resulting in total choline concentrations in the MR of 1650 mg/kg for C0 was, 2350 mg/kg for C700 was, 3050 mg/kg for C1400, and 3750 mg/kg for C2100. Calves were weaned at 49 d, and the trial ended at 56 d. Body weight (BW) was measured at d 0, 14, 28, 42, 49 and 56. Fecal scores were measured weekly. Feed intake was measured daily and calculated bi-weekly. All feeding, body weight measurements, and fecal scoring were conducted by the research staff at the University of Minnesota SROC. Growth, feed intake, and gain to feed ratio were analyzed using a linear mixed effects model with choline concentration as a fixed effect and source herd and room as random effects. Initial body weight was included as a covariate for average daily gain. Fecal scores were analyzed as a chi-squared test of significance. Feeding 700 mg/kg supplemental choline increased MR intake throughout the preweaning period and increased ADG in both the preweaning and postweaning periods compared with the other treatments. No differences were observed for fecal scores across treatments. Results suggest that calf performance can be improved with MR containing 2350 mg/kg choline, contrasting with current NASEM (2021) requirements of 1000 mg/kg.

Risk Evaluation in Occupational Safety and Health Research: Results From a Benchmarking Exercise of Federal and Academic IRBs.

Research involving working populations can pose unique ethical and risk evaluation challenges. The purpose of this benchmarking project was to assess how federal agencies and academic institutions approach the interpretation and application of key risk evaluation concepts in research involving workers in their places of employment. Key informant interviews were conducted to ascertain current practices related to assessing soundness of research design, determining risk reasonableness and research relatedness of risks, and evaluating the risk of noninvasive clinical tests in occupational settings. There were noteworthy commonalities among the approaches described to review and address critical aspects of risk evaluation for occupational safety and health research involving human participants. The insights gleaned may help guide institutional review boards and Human Research Protection Programs as they consider the ethical issues of human subjects research in occupational settings.

Dynamic Cognitive-Motor Training versus Cognitive Computer-Based Training in People with Multiple Sclerosis: A Preliminary Randomized Controlled Trial with 2-Month Follow-Up.

Background: Recent studies underscore the intricate relationship between cognitive and motor impairments in Multiple Sclerosis (MS), often exacerbated by CNS damage compromising neural connections. These cognitive-motor deficits contribute to reduced efficiency in daily activities and heightened risks of falls and accidents. The combination of challenging cognitive-motor training in a more ecological setting could improve cognitive functions in people with MS (PwMS). Objective: This study aims to compare the impact of dynamic cognitive-motor training versus computer-based cognitive training on overall cognitive efficiency in PwMS. Methods: Thirty-eight PwMS were recruited through the neurorehabilitation services of an Institute of research and health. Twenty-four participants were randomly assigned to the Cognitive-Motor group (CMg) and Cognitive Therapy group (CTg). Participants underwent three training sessions per week for four weeks, each lasting 50 min. The primary outcome was a comprehensive cognitive assessment using the Cognitive Impairment Index (CII), and the secondary outcomes were the Multiple Sclerosis Quality of Life Questionnaire MSQOL-54 and the Stroop Color Word Interference Test (SCWT). Results: Significant differences in the CII scores across T0, T1, and T2, as indicated by Friedman's test (χ2(2) = 14.558, p = .001), were found in the CMg. A significant difference in the change in health subscale of the MSQOL-54 was observed when comparing the groups across T0, T1, and T2 (χ2(2) = 6.059, p = .048). There were also statistically significant differences for the emotional well-being (χ2(2) = 7.581, p = .023) and health distress (χ2(2) = 11.902, p = .003) subscales. Post hoc analysis showed a statistically significant improvement in health-related quality of life (HRQOL) for the former at T1 vs. T0 (Z = -2.502, p = .012 and for the latter at T2 vs. T0 (Z = -2.670, p = .008), respectively. Conclusions: Our results support the combination of cognitive-motor training to enhance cognitive functional outcomes and quality of life compared to computer-based cognitive training in PwMS.

The effects of climate extreme events on selected food crop yields in Sub-Saharan Africa

The agricultural sector is essential for economic growth. However, agricultural performance can be limited by factors such as climatic risks. This paper aims to analyse the effect of climate extreme events on selected food crop yield in sub-Saharan Africa (SSA). The study uses data from the Food and Agriculture Organisation (FAO) database for maize, rice, and sorghum yields. Also, we used data obtained from the International Disaster Database of the Centre for Research on the Epidemiology of Disasters (CRED) for floods and droughts over the period 1990–2020. The data were analysed based on the Fully Modified Ordinary Least Squares (FMOLS). The results showed that climate extreme events negatively affected maize, rice and sorghum yields. Also, the findings showed that floods and droughts in past years negatively influence current yields of maize, rice and sorghum. Moreover, agricultural labour force, fertilizer and financial development are the main transmission channels through which floods and droughts can affect maize, rice and sorghum yields. The study concludes by recommending that policies aimed at promoting climate change adaptation measures as well as agricultural insurance could make the agriculture sector more resilient to climate extreme events and in turn that could improve agricultural productivity and reduce food insecurity.

Predicting skin cancer risk from facial images with an explainable artificial intelligence (XAI) based approach: a proof-of-concept study

Efficient identification of individuals at high risk of skin cancer is crucial for implementing personalized screening strategies and subsequent care. While Artificial Intelligence holds promising potential for predictive analysis using image data, its application for skin cancer risk prediction utilizing facial images remains unexplored. We present a neural network-based explainable artificial intelligence (XAI) approach for skin cancer risk prediction based on 2D facial images and compare its efficacy to 18 established skin cancer risk factors using data from the Rotterdam Study. The study employed data from the Rotterdam population-based study in which both skin cancer risk factors and 2D facial images and the occurrence of skin cancer were collected from 2010 to 2018. We conducted a deep-learning survival analysis based on 2D facial images using our developed XAI approach. We subsequently compared these results with survival analysis based on skin cancer risk factors using cox proportional hazard regression. Among the 2810 participants (mean Age=68.5±9.3 years, average Follow-up=5.0 years), 228 participants were diagnosed with skin cancer after photo acquisition. Our XAI approach achieved superior predictive accuracy based on 2D facial images (c-index=0.72, 95% CI: 0.70-0.74), outperforming that of the known risk factors (c-index=0.59, 95% CI 0.57-0.61). This proof-of-concept study underscores the high potential of harnessing facial images and a tailored XAI approach as an easily accessible alternative over known risk factors for identifying individuals at high risk of skin cancer. The Rotterdam Study is funded through unrestricted research grants from Erasmus Medical Center and Erasmus University, Rotterdam, Netherlands Organization for the Health Research and Development (ZonMw), the Research Institute for Diseases in the Elderly (RIDE), the Ministry of Education, Culture and Science, the Ministry for Health, Welfare and Sports, the European Commission (DG XII), and the Municipality of Rotterdam.

Preliminary design of an AXUV photodiode-based bolometer camera for MT-I spherical tokamak

The MT-I is a spherical tokamak at the Pakistan Tokamak Plasma Research Institute, and has a major radius of 15 cm and a minor radius of 9 cm. This paper presents the design and computational analysis of the Absolute eXtreme Ultra-Violet (AXUV) photodiode-based bolometer camera, which will be used for the first time in the MT-I tokamak. The bolometer camera contains a single array of 16 AXUV photodiodes placed behind an aperture to compute the line of sight (LOS) and field of view (FOV) of the system. This array is located at the midplane of the vessel, which provides a radial resolution of about 16 mm. The individual FOV of each photodiode and the collective FOV of the array are 4.1° and ±34.5°, respectively. The impurity densities and their cooling rates for elements like carbon, oxygen, and iron are used to compute the plasma emissivity distribution, the power incident on the photodiode array, and signal-to-noise ratio (SNR) analysis. The analysis reveals that the radiated power loss is about 10 % of the ohmic heating input power. The geometrical etendue falls within the range of 2.2 × 10−5 to 3.2 × 10−5 Sr cm2. The bolometer exhibits a frequency response bandwidth of 10 kHz, and its temporal resolution is around 0.1 milliseconds.

Physico-chemical, functional, pasting and structural characteristics of two malted maize flours produce under optimal conditions

Maize is a popular gluten-free grain, used in many dishes in Africa and elsewhere. It provides numerous nutrients (especially starch) and contains antinutritional factors (phytates). To reduce these factors and improve the nutritional and physical potential of maize, a number of treatments are required, including malting. This study therefore investigated the physicochemical, functional, structural, and pasting properties of two malted maize varieties (Atp-Y and Coca-sr) produce under optimal conditions. After receiving the two maize varieties from the Agricultural Research Institute for development, the Atp-Y variety was soaked for 30 h at 18.66 °C with 0.37% plant salt, followed by germination at 30 °C for 218.58 h and a ripening period of 40 h, while the Coca-sr variety was soaked for 3.90 h at 20.57 °C with 0.0219% plant salt, followed by germination at 30 °C for 251.55 h and a ripening period of 58.73 h. The flours obtained were subjected to physicochemical, structural, pasting and functional analysis. These analyses showed that the protein, fibre, ash, carbohydrate, starch and energy density content were significantly influenced by the variety. The Atp-Y variety had the highest contents of Ca (855.00 mg/100 g), Na (125.36 mg/100 g) and Cu (0.53 mg/100 g). The availability of Ca, Na and divalent cations was significantly higher in the Atp-Y variety. The Coca-sr variety contributed the most to achieving the protein (40.02 to 73.88%) and lipid (27.30 to 38.08%) requirements of children aged 0 to 59 months. The contents of phytates, cyanides and condensed tannins were similar in both varieties, while oxalates (7.88 mg/100 g), trypsin inhibitors (2.07 mg/100 g) and hydrolyzed tannins (15.02 mg EC/g) were more abundant in the Coca-sr variety. Phenols, flavonoids and saponins ranged between 45.96 and 68.39 mg GAE/g, 32.13 and 39.27 mg CE/g and 0.45 mg/100 g, respectively. No significant differences were found in the physical and functional properties, although the Atp-Y variety had a higher water retention and swelling capacity. Malting variety and conditions had no significant effect on Pasting Time, Setback, Setback ratio and Stability ratio in contrast to Pasting Temperature, Peak viscosity, Holding viscosity, Breakdown and Final viscosity. The Atp-Y grade exhibited the highest pasting parameters when pasting temperature was excluded. Scanning electron microscopy showed that the microscopic structure varied from one variety to another, although the grains had similar sizes. The Microscopic dispersions of grains testifies to the enzymatic activity in the Coca-sr variety, the compact surface layer with protruding grains testifies to the fiber richness of the Atp-Y variety. The grain distribution of the particles showed that more than 50% of the grains in both types were 400 µm in size. X-ray diffraction (XRD) showed that the degradation of the crystalline structure of the starch depended on the variety and the physiological phenomena taking place there. These results clearly show that these flours are well suited for the formulation of foods with high energy and nutritional value. However, they could also be used as sweeteners in panification or as raw materials in the brewing industry.

Seedlings growth from different age of rubber trees (Hevea brasiliensis Muell. Arg.) experiencing repeated leaf fall

The budding technique propagation requires rootstock, which are raised from rubber seeds. Due to repeated leaf fall disease since 2015, seed production dropped and threatened the rubber-replanting program. Amid this situation, young trees may be a temporary source of the seeds for rootstocks, which under normal conditions is not recommended. To test this hypothesis, a comparison of germination rate, seedling growth, and biomass accumulation of the seeds from young and mature PB 260 rubber trees was carried out at Sungei Putih Research Unit, Indonesian Rubber Research Institute, North Sumatra, Indonesia. The study showed that the germination rate of the seeds was low i.e. 7.23 + 2.96 % of young plants and 21.96 + 13.51 % of mature plants respectively, both were below normal values around 70 – 80%. After germination, no significant difference was found in the growth of seedlings from young trees and their mature counterparts. The root/shoot ratio exhibited no significant difference between the two types of seedlings observed, indicating a similar biomass accumulation capability. In the condition when seed supply was limited due to leaf fall disease, the seeds of young trees might be used as a temporary source with standard selection protocols should be implied.

Orchestration for quantum services: The power of load balancing across multiple service providers

Quantum computing plays a crucial role in solving complex problems for which classical supercomputers require an impractical amount of time. This emerging paradigm has the potential to revolutionize various fields such as cryptography, chemistry, and finance, making it a highly relevant area of research and development. Major companies such as Google, Amazon, IBM, and Microsoft, along with prestigious research institutions such as Oxford and MIT, are investing significant efforts into advancing this technology. However, the lack of a standardized approach among different providers poses challenges for developers to effectively access and utilize quantum computing resources. In this study, we propose a quantum orchestrator that is designed to facilitate the orchestration and execution of quantum circuits across multiple quantum service providers. The proposed solution aims to simplify the process for developers and facilitate the execution of quantum tasks using resources offered by different providers. The proposal is validated with the implementation of the proposed orchestrator for Amazon Braket and IBM Quantum. It can support both quantum and classical developers in defining, configuring, and executing circuits independently of the selected provider.

Study revealed that three spray of fipronil 5 SC @ 1 ml/l or emamectin benzoate 5 SG @ 0.4 g/l can be suggested to the farmers for the management of pest complex on capsicum under shade net house conditions during summer for off season production.

MAPT H2 haplotype and risk of Pick's disease in the Pick's disease International Consortium: a genetic association study

Pick's disease is a rare and predominantly sporadic form of frontotemporal dementia that is classified as a primary tauopathy. Pick's disease is pathologically defined by the presence in the frontal and temporal lobes of Pick bodies, composed of hyperphosphorylated, three-repeat tau protein, encoded by the MAPT gene. MAPT has two distinct haplotypes, H1 and H2; the MAPT H1 haplotype is the major genetic risk factor for four-repeat tauopathies (eg, progressive supranuclear palsy and corticobasal degeneration), and the MAPT H2 haplotype is protective for these disorders. The primary aim of this study was to evaluate the association of MAPT H2 with Pick's disease risk, age at onset, and disease duration. In this genetic association study, we used data from the Pick's disease International Consortium, which we established to enable collection of data from individuals with pathologically confirmed Pick's disease worldwide. For this analysis, we collected brain samples from individuals with pathologically confirmed Pick's disease from 35 sites (brainbanks and hospitals) in North America, Europe, and Australia between Jan 1, 2020, and Jan 31, 2023. Neurologically healthy controls were recruited from the Mayo Clinic (FL, USA, or MN, USA between March 1, 1998, and Sept 1, 2019). For the primary analysis, individuals were directly genotyped for the MAPT H1-H2 haplotype-defining variant rs8070723. In a secondary analysis, we genotyped and constructed the six-variant-defined (rs1467967-rs242557-rs3785883-rs2471738-rs8070723-rs7521) MAPT H1 subhaplotypes. Associations of MAPT variants and MAPT haplotypes with Pick's disease risk, age at onset, and disease duration were examined using logistic and linear regression models; odds ratios (ORs) and β coefficients were estimated and correspond to each additional minor allele or each additional copy of the given haplotype. We obtained brain samples from 338 people with pathologically confirmed Pick's disease (205 [61%] male and 133 [39%] female; 338 [100%] White) and 1312 neurologically healthy controls (611 [47%] male and 701 [53%] female; 1312 [100%] White). The MAPT H2 haplotype was associated with increased risk of Pick's disease compared with the H1 haplotype (OR 1·35 [95% CI 1·12 to 1·64], p=0·0021). MAPT H2 was not associated with age at onset (β -0·54 [95% CI -1·94 to 0·87], p=0·45) or disease duration (β 0·05 [-0·06 to 0·16], p=0·35). Although not significant after correcting for multiple testing, associations were observed at p less than 0·05: with risk of Pick's disease for the H1f subhaplotype (OR 0·11 [0·01 to 0·99], p=0·049); with age at onset for H1b (β 2·66 [0·63 to 4·70], p=0·011), H1i (β -3·66 [-6·83 to -0·48], p=0·025), and H1u (β -5·25 [-10·42 to -0·07], p=0·048); and with disease duration for H1x (β -0·57 [-1·07 to -0·07], p=0·026). The Pick's disease International Consortium provides an opportunity to do large studies to enhance our understanding of the pathobiology of Pick's disease. This study shows that, in contrast to the decreased risk of four-repeat tauopathies, the MAPT H2 haplotype is associated with an increased risk of Pick's disease in people of European ancestry. This finding could inform development of isoform-related therapeutics for tauopathies.

Adiposity, immunity, and inflammation: interrelationships in health and disease: A report from 24th annual Harvard nutrition obesity symposium, June 2023

The rapidly evolving field of immunometabolism explores how changes in local immune environments may affect the key metabolic and cellular processes, including that of adipose tissue. Importantly, these changes may contribute to low-grade systemic inflammation. In turn, chronic low-grade inflammation affecting adipose tissue may exacerbate the outcome of metabolic diseases. Novel advances in our understanding of immune-metabolic processes may critically lead to interventions to reduce disease severity and progression. An important example in this regard relates to obesity, which has a multifaceted effect on immunity activating the pro-inflammatory pathways such as inflammasome and disrupting cellular homeostasis. This multifaceted effect of obesity can be investigated through study of downstream conditions using cellular and systemic investigative techniques. To further explore this field, the NIH P30 Nutrition Obesity Research Center at Harvard in partnership with the Harvard Medical School assembled experts to present at its 24th annual Symposium entitled “Adiposity, Immunity, and Inflammation: Interrelationships in Health and Disease on June 07, 2023. This manuscript seeks to synthesize and present key findings from the symposium highlighting new research and novel disease-specific advances in the field. Better understanding the interaction between metabolism and immunity offers promising preventative and treatment therapies for obesity-related immunometabolic diseases.

PEDAGOGICAL REGIONAL STUDIES AS INTERDISCIPLINARY SCIENTIFIC KNOWLEDGE

The article reveals the peculiarities and prospects for the development of pedagogical regional studies as interdisciplinary scientific knowledge and a multidimensional phenomenon of education, culture, and science. It was established that in the conditions of modern social changes, the need for the crystallization of national identity as the basis of Ukrainian statehood, the historical and cultural approach plays an important role in the training of future specialists – citizens of Ukraine. Among the modern trends in the development of Ukrainian education and pedagogy is the actualization of regional research, which is manifested in the appeal of scientists to various aspects of pedagogical local history, microhistory, etc. The regional approach is based on highlighting the patterns of development of national education and pedagogical thought on little-known, unique regional materials. One of the aspects of such a regional approach is the subject of research in pedagogical regional studies – interdisciplinary knowledge about the peculiarities of the development of education, science, pedagogical thought, the culture of the region, the study, preservation and creative use of regional pedagogical experience in the theory and practice of modern educational institutions, scientific institutions, institutions of the social sphere . The authors analyzed the experience of the Scientific and Research Center of Pedagogical Local Studies operating at the Pavlo Tychyna Uman State Pedagogical University. In 2022, with the aim of updating regional scientific problems, studying little-known pages of pedagogical local history, scientists of the Pavlo Tychyna Uman State Pedagogical University launched a new research project – «Education, schooling and pedagogical thought of Cherkasy region». The purpose of the project is to present to the public the achievements of Ukrainian and foreign pedagogical science and of education, consolidating biographical and bibliographic information about teachers, educators, teachers in the form of an informational and bibliographic electronic resource «Pedagogical Cherkasy» and a popular science reference book. It has been established that the relevance of regional scientific issues is enhanced by the multidimensionality and interdisciplinary nature of pedagogical regional studies as a pedagogical, historical, and social phenomenon that requires a thorough study in order to present it representatively in the modern interdisciplinary historical and cultural discourse – educational, social-pedagogical, historical-pedagogical, etc.
