The high-confinement mode (H-mode) significantly enhances the energy and particle confinement in fusion plasma compared with the low-confinement mode (L-mode), and it is the basic operation scenario for ITER and CFETR. Edge localized mode (ELM) often appears in H-mode, helping to expel impurities to maintain a longer stable state. However, the particle burst and energy burst from ELM eruptions can severely damage the first wall of fusion device, so, it is necessary to control the ELM. Experiments on EAST tokamak and HL-2A tokamak have been conducted with ELM mitigation by lower hybrid wave (LHW), confirming the effect of LHW on ELMs, but the physical mechanism of ELM mitigation by LHW is still not fully understood. In this paper, the influences of LHW injection on the linear and nonlinear characteristics of peeling-ballooning mode (P-B mode) are investigated in the edge pedestal region of H-mode plasma in tokamak by using the BOUT++ code. The simulations take into consideration both the conventional main plasma current driven by LHW and the three-dimensional perturbed magnetic field generated by the scrape-off layer helical current filament (HCF) on the P-B mode. The linear results show that the core plasma current driven by LHW moves the linear toroidal mode spectrum towards higher mode numbers and lower growth rates by reducing the normalized pressure gradient and magnetic shear of the equilibrium. Nonlinear simulations indicate that due to the broadening of the linear mode spectrum, the core current driven by LHW can reduce the pedestal energy loss caused by ELM through globally suppressing different toroidal modes of the P-B mode, and the three-dimensional perturbed magnetic field generated by LHW-driven HCF can reduce the energy loss caused by ELMs through promoting the growth of modes other than the main mode and enhancing the coupling between different modes. It is found in the study that the P-B mode promoted by the three-dimensional perturbed magnetic field generated by HCF has a mode number threshold, and when the dominant mode of the P-B mode is far from the mode number threshold driven by the three-dimensional perturbed magnetic field, the energy loss due to ELMs is more significantly reduced. These results contribute to a more in-depth understanding of the physical mechanism in ELM control experiment by LHW.

Published: March 2024

Many successful researchers in the biomedical sciences have benefitted from mentors and networks earlier in their career. However, early-career researchers from minoritized and underrepresented groups do not have the same access to potential mentors and networks as many of their peers. In this article we describe how ‘cold emails’ and social media platforms – notably Twitter/X and LinkedIn – can be used to build virtual networks, and stress the need to invest in maintaining networks once they have been established.
The experience of a tele-operated avatar being touched increases operator’s sense of discomfort
Authors: Kimoto Mitsuhiko , Shiomi Masahiro
Published: March 2024

Recent advancements in tele-operated avatars, both on-screen and robotic, have expanded opportunities for human interaction that exceed spatial and physical limitations. While numerous studies have enhanced operator control and improved the impression left on remote users, one area remains underexplored: the experience of operators during touch interactions between an avatar and a remote interlocutor. Touch interactions have become commonplace with avatars, especially those displayed on or integrated with touchscreen interfaces. Although the need for avatars to exhibit human-like touch responses has been recognized as beneficial for maintaining positive impressions on remote users, the sensations and experiences of the operators behind these avatars during such interactions remain largely uninvestigated. This study examines the sensations felt by an operator when their tele-operated avatar is touched remotely. Our findings reveal that operators can perceive a sensation of discomfort when their on-screen avatar is touched. This feeling is intensified when the touch is visualized and the avatar reacts to it. Although these autonomous responses may enhance the human-like perceptions of remote users, they might also lead to operator discomfort. This situation underscores the importance of designing avatars that address the experiences of both remote users and operators. We address this issue by proposing a tele-operated avatar system that minimizes unwarranted touch interactions from unfamiliar interlocutors based on social intimacy.
Beliefs, barriers, and promotion practices of Indian nurses’ regarding healthy eating for cancer survivors in a tertiary care hospital—A cross sectional survey

Published: March 2024

Purpose

To describe the beliefs, barriers and promotion practices of Indian nurses’ regarding healthy eating (HE) behaviours amongst cancer survivors, and to gain insights into whether their educational qualifications might affect the promotion of HE.

Methods

Data was gathered using a validated questionnaire, 388 of the approached 400 nurses who worked at a tertiary care hospital in India gave informed consent to participate in the study. The Mann-Whitney U test and the Chi square analysis (for continuous and categorical variables respectively) were performed to carry out sub-group comparisons based on the qualification of the nurses i.e., Bachelor of Science in Nursing (BSc) and General Nursing and Midwifery (GNM).

Results

The nurses believed that dieticians/nutritionists were primarily responsible for educating the cancer survivors regarding HE. HE was promoted by nurses’ relatively equally across multiple treatment stages (“during” treatment 24.4%, “post” treatment 23.1%; and “pre” treatment 22.3%). Nurses’ believed HE practices had numerous benefits, with improved health-related quality of life (HRQoL) (75.7%), and mental health (73.9%) being the most frequent responses. The most frequently cited barriers by the nurses in promoting HE were lack of time (22.2%), and lack of adequate support structure (19.9%). Sub-group comparisons generally revealed no significant difference between the BSc and GNM nurses in their perceptions regarding HE promotion to cancer survivors. Exceptions were how the GNM group had significantly greater beliefs regarding whether HE can “reduce risk of cancer occurrence” (p = 0.004) and “whether or not I promote HE is entirely up to me” (p = 0.002).

Conclusion

The nurses in India believe in the promotion of HE practices among cancer survivors across various stages of cancer treatments. However, they do face a range of barriers in their attempt to promote HE. Overcoming these barriers might facilitate effective promotion of HE among cancer survivors and help improve survivorship outcomes.

Implications for cancer survivors

Indian nurses employed in the two tertiary care hospitals wish to promote HE among cancer survivors, but require further knowledge and support services for more effective promotion of HE.
Superconductivity in a topological weyl semimetal
Authors:   , Esparza Urrutia Juan Pablo
Published: March 2024

In this work, we determine the possible superconducting states produced in a type-I Weyl semimetal under a generic interaction, according to the topological nature of the Cooper pair. Once identified, we study the competition and coexistence between those states. At finite temperature, we find a set of conditions, in terms of the quantum numbers and the angular distribution of the pairing gaps, that needs to be fulfilled in order to produce coexistence of the phases. We also characterize the specific heat, finding the typical lambda transition at each phase transition, in concordance with the literature. At zero temperature, we find generic self-consistent equations for the pairing gaps, written exclusively in terms of the value of its quantum numbers and its angular distribution. Using the examples that our model predicted, we show that in general the phases with different topology coexist in a certain zone of the phase space, in the vicinity of the curve along which the effective couplings for each channels are equal. Finally, in what refers to the topological repulsion mechanism proposed in previous work on the topic, we conclude that a feature needed in order to produce such phenomena is the asymmetry in the position of the Weyl points, codified in the different values of chemical potential at each node.

The silkworm Bombyx mori.L. is infected by various diseases viz; grasserie, flacherie, muscardine, and pebrine. Among all these diseases the grasserie causes major economic loss to the industry and is one of the main reasons for low silk productivity. It is caused by a virus known as Bombyx mori nucleopolyhedro virus (BmNPV). The impact of grasserie disease on silkworms is significant as it leads to reduced silk production and can result in economic losses for sericulture farmers. In India greater than 50% of silk cocoon crop loss is due to BmNPV [1] and in Kashmir valley, the loss is about 28-32% [2]. Silk obtained from the cocoons of silkworm Bombyx mori L. is a natural fibrous protein well known for being lightweight, having high mechanical strength, good flexibility, and luster making it ideal for the textile industry. In addition, fibroin extracted from the cocoons of domesticated silkworm Bombyx mori L. has gained growingly interest due to its excellent mechanical properties and high biocompatibility, biodegradability, inexpensiveness, and preparation flexibility [3]. These properties of silk fibroin lead to the formulation of fibroin nanoparticles (FNP’-s) which can be used to encapsulate different types of therapeutic compounds like proteins, vaccines, enzymes, etc. Fibroin has been approved as a biomaterial by the Food and Drug Administration (FDA) and has been popularly used in numerous medical applications such as sutures, tissue regeneration, coating devices, and drug delivery systems [4]. It has been studied that SF-derived curcumin nanoparticles show higher efficacy against breast cancer cells and have the potential to treat in vivo breast tumors by local, sustained, and long-term therapeutic delivery as a biodegradable system [5]. Therefore, fibroin-coated nanoparticles can be used effectively for disease management.

Authors: Robinson Ebbi Donald , Ononugbo Chinyere Philomena , Gbarato Oliver
Published: March 2024

Aim: Computed tomography (CT) is an innovation that has contributed immensely to modern medicine. CT uses ionising radiation in the form of x-rays which has become a source of concern. The study is to evaluate patients’ doses during 2 and 16 slices CT scan procedure in adults.

Study Design:  The study was an empirical study.

Place and Duration of Study: It was carried out with 50 patients referred for brain CT in two separate radiology facilities having 2 and 16 slices CT scans in Port Harcourt over 6months duration.

Methodology: The examination was done in accordance with standard protocols for brain CT. Radiation dose was measured with a coded themoluminiscent dosimeter (TLD) chip, placed on the glabella and held in position with a transparent adhesive tape before the exposures and removed immediately after the investigation, labeled and sent to the Radiation Dosimetric Laboratory of the Regional Centre for Energy Research and Training (CERT), Zaria for reading. The effective dose was obtained from the absorbed dose by multiplying the absorbed dose with tissue weighting factor of 0.01 for the brain. The cancer and hereditary effects per investigation were obtained by using the cancer risk coefficients (FCR = 5.5X10−2 Sv−1) and hereditary risk coefficients (FGE = 0.2X10−2 Sv−1) obtained from ICRP 103 publication. All variables collated were tabulated into a data sheet and analyzed using Statistical Package for Social Sciences (SPSS) windows version 22.30 statistical software (SPSS Inc, Chicago, Illionois, USA). The results were presented on tables, charts and graphs. A descriptive statistical tool was used to - determine central tendencies while Pearson correlation and linear regression analysis model was used to evaluate correlation between variables.

Results: The mean absorbed dose (±SD) was 51.37(±8.07)mSv and 89.97±13.25mSv during 2 and 16 slices CT procedures respectively. The Lifetime Attributable Risk is approximately 3 and 5 per 105 CT procedures during 2 and 16 slice CT procedures while the Hereditary Risks was 1 and 2 per 106 CT procedures for 2 and 16 slice CT procedures respectively. There was a weak correlation between BMI and cancer risk with a Pearson Correlation coefficient (r) of 0.130 but no association between cancer risk and age during 2 slice CT scanner.

Conclusion: Absorbed dose increases with increase on the CT slices, likewise cancer and hereditary risk increases with increase in CT slices. Thus, notwithstanding how low a radiation exposure could be it can still necessitate malignant risk.

Sub-Saharan Africa faces significant challenges as a net importer of rice, with self-sufficiency rates plummeting to as low as 14% in countries like Kenya. The Mwea irrigation scheme shoulders the bulk of rice cultivation, contributing over 80% of the country’s production. However, productivity within the scheme has seen a concerning decline, dropping from 5.6 ─ 6.0 t ha-1 to 1.3 ─ 4.6 t ha-1 between 1977 and 2018. This decline could be attributed to site-specific nutritional deficiencies and/or toxicities, rendering generalized agronomic recommendations ineffective in certain areas. To address this problem, our study aimed to assess soil chemical properties variability within the Mwea irrigation scheme, identify clusters with similar nutritional status, and tailor area-specific agronomic recommendations. During May to September 2020, we collected and analyzed four hundred samples from five sections of the scheme for total organic carbon, soil pH, macro and micronutrients, and exchangeable cations. Principal component analysis was conducted on the mean values of the soil chemical properties to identify significant contributors to variation and establish zones with similar patterns. Principal components 1 to 4 collectively explained 72.2% of the total variability. Cluster analysis revealed four distinct clusters, namely MW, TB, KT, and MU. Within cluster MW, soil pH was below the optimum range for rice cultivation, suggesting a need for liming. Potassium deficiency was observed across all clusters, with rice straw incorporation recommended as a long-term solution. Furthermore, zinc deficiency was noted in cluster WU, necessitating zinc fertilizer application. Conversely, iron toxicity was a concern in cluster MW, suggesting the adoption of alternating wetting and drying techniques and cultivating tolerant varieties. By proving tailored recommendations based on localized soil conditions, we aim to bolster rice productivity within the Mwea irrigation scheme and contribute to regional food security efforts.

Published: March 2024

Assessing genetic variability makes it easier to identify stronger genotypes, allowing to produce high-yielding crops that are climatically resilient and promote efficient crop improvement. The present study aimed to assesses the genetic variability, association study & path analysis of 51 chickpea [Cicer arietinum (L.)] genotypes on 12 characteristics. The experiment utilized Randomized complete block design with three replications conducted in Phagwara, Punjab. The ANOVA recorded significant variance at the 1% level for all traits, indicating considerable variability amongst germplasm. SY expressed comparatively high Genotypic coefficient of variance and heritability with other traits, indicating that it is the most heritable trait and has the highest potential for improvement through selective breeding. Positive correlation with SY was revealed by PH, NPB, NSB, NPP, NFP, TW, BY, HI. Path analysis revealed that NFP had highest positive effect on SY followed by NUFP, HI, BY, NSB, TW, DFF & DM suggesting selection from any of these traits would be beneficial. When selecting traits to improve yield in chickpea through breeding, it is essential to focus on specific characteristics that directly contribute to higher production. This research will help understand yield-influencing factors for resilient chickpea varieties in Punjab environmental conditions.

Body size and scaling of the hands and feet of prosimian primates
Authors: Lemelin Pierre , Jungers William L.
Published: March 2007

The hands and feet of primates fulfill a variety of biological roles linked with food acquisition and positional behavior. Current explanations of shape differences in cheiridial morphology among prosimians are closely tied to body size differences. Although numerous studies have examined the relationships between body mass and limb morphology in prosimians, no scaling analysis has specifically considered hand and foot dimensions and intrinsic proportions. In this study, we present such an analysis for a sample of 270 skeletal specimens distributed over eight prosimian families. The degree of association between size and shape was assessed using nonparametric correlational techniques, while the relationship between each ray element length and body mass (from published data and a body mass surrogate) was tested for allometric scaling. Since tarsiers and strepsirrhines encompass many taxa of varying degrees of phylogenetic relatedness, effective degrees of freedom were calculated, and comparisons between families were performed to partially address the problem of statistical nonindependence and “phylogenetic inertia.” Correlational analyses indicate negative allometry between relative phalangeal length (as reflected by phalangeal indices) and body mass, except for the pollex and hallux. Thus, as size increases, there is a significant decrease in the relative length of the digits when considering all prosimian taxa sampled. Regression analyses show that while the digital portion of the rays scales isometrically with body mass, the palmar/plantar portion of the rays often scales with positive allometry. Some but not all of these broadly interspecific allometric patterns remain statistically significant when effective degrees of freedom are taken into account. As is often the case in interspecific scaling, comparisons within families show different scaling trends in the cheiridia than those seen across families (i.e., lorisids, indriids, and lemurids exhibit rather different allometries). The interspecific pattern of positive allometry that appears to best characterize the metapodials of prosimians, especially those of the foot, parallels differences found in the morphology of the volar skin. Indeed, relatively longer metapodials appear to covary with flatter and more coalesced volar pads, which in turn slightly improve frictional force for animals that are at a comparative disadvantage while climbing because of their larger mass. Despite the essentially isometric relationship found between digit length and body mass across prosimians, examination of the residual variation reveals that tarsiers andDaubentoniapossess, relative to their body sizes, remarkably long fingers. Such marked departures between body size and finger length observed in these particular primates are closely linked with specialized modes of prey acquisition and manipulation involving the hands.

Reactive blending of polyamides with epoxidized elastomers
Authors: Steller Ryszard T. , Micewicz Ewa , Meissner Wanda
Published: March 2007

Melt blending of aliphatic polyamides (PA6, PA66, PA12) with epoxidized and nonepoxidized elastomers (SBS, BS, PB) was investigated. IR and rheological studies have shown that epoxidized elastomers can simultaneously react both with polyamides and within their own phases during melt blending. Relative intensity of both processes is the main factor, which determines structure and properties of blends. SEM observations indicated that use of epoxidized elastomers improves blend homogeneity and decreases mean size of dispersed elastomer phase in comparison with nonepoxidized elastomers. Mechanical properties of epoxidized elastomers based blends are generally better with respect to similar blends with nonepoxidized elastomers. They depend on blend composition and type of polyamide and elastomer. Elastomer addition decreases tensile strength of all systems but in some cases, a considerable rise of impact strength was measured. Epoxidized SBS block copolymer was found to be the most effective modifier, especially with respect to PA6 and PA12. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007

Dibutylamine‐terminated ε‐caprolactone oligomers (CLOs: CLOL, CLOM, and CLOH) with number–averaged molecular weight (Mn), 500, 1300, and 2200, respectively, were synthesized by the ring‐opening polymerization of ε‐caprolactone initiated by 2‐(dibutylamino)ethanol in the presence of tin(II) 2‐ethylhexanoate. Nanocomposites based on poly(ε‐caploractone) (PCL) and the caprolactone oligomer‐treated montmorillonites (CLO‐Ms: CLOL‐M, CLOM‐M, and CLOH‐M) were prepared by melt intercalation method. The XRD and TEM analyses of the PCL composites revealed that the extent of exfoliation of the clay platelets increased with increasing molecular weight of the used CLOs. Tensile strength and modulus of the PCL/CLO‐M composites increased with increasing molecular weight of the CLO and increasing inorganic content. The tensile modulus of the PCL/CLOH‐M nanocomposite with inorganic content 5.0 wt % was three times higher than that of control PCL. Among the PCL/CLO‐M composites, the PCL/CLOM‐M composite had the highest crystallization temperature and melting temperature. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007

Published: March 2007

By using laser light scattering (LS) and size exclusion chromatography combined LS, we have investigated the molecular weight and chain conformation of amylopectin from rice of India (II‐b), japonica (IJ‐b), and glutinous (IG‐b) in dimethyl sulfoxide (DMSO) solution. The weight‐average molecular weight (Mw) and radius of gyration (〈S2〉½) of amylopectin were determined to be 4.06 × 107 and 128.5 nm for India rice, 7.41 × 107 and 169.6 nm for japonica rice, 2.72 × 108 and 252.3 nm for glutinous rice, respectively. The 〈S2〉½ values were much lower than that of normal polymers, indicating a small molecular volume of amylopectin, as a result of highly branched structure. Ignoring the difference of degree of branching, approximated dependences of 〈S2〉½ and intrinsic viscosity ([η]) on Mw for amylopectin in DMSO at 25°C were estimated to be 〈S2〉½ = 0.30Mw0.35 (nm) and [η] = 0.331Mw0.41 (mL g−1) in the Mw range studied. Moreover, from the 〈S2〉½ values of numberless fractions obtained from many experimental points in the SEC chromatogram detected with LS, the dependence of 〈S2〉½ on Mw for the II‐b sample was estimated also to be 〈S2〉½ = 0.34 Mw0.347, coinciding with the above results. © 2007 Wiley Periodicals, Inc.

Published: March 2007

The tri‐n‐butyl phosphate‐nitric acid (TBP‐HNO3) complex prepared by contacting the pure TBP with the concentrated HNO3 can be used for direct dissolution of lanthanide and actinide oxides in the supercritical fluid carbon dioxide (SCF‐CO2). Properties of the TBP‐HNO3 complex have been studied. Experimental results showed that when the initial HNO3/TBP volume ratio was varied from 1:7 to 5:1, the concentration of HNO3 in the TBP‐HNO3 complex changed from 1.95 to 5.89 mol/L, the [HNO3]/[TBP] ratio of the TBP‐HNO3 complex changed from 0.61 to 2.22, and the content of H2O in the TBP‐HNO3 complex changed from 2.02% to 4.19%. All of the density, viscosity and surface tension of the TBP‐HNO3 complex changed with the concentration of HNO3 in the complex, and were higher than those of the pure TBP. The protons of HNO3 and H2O in the complex underwent rapid exchange to exhibit a singlet resonance peak in nuclear magnetic resonance spectra. When the TBP‐HNO3 complex was dissolved in a low dielectric constant solvent, small droplets of HNO3 were formed that can be detected by NMR.

Published: March 2007

The first histidine catalyzed direct aldol reactions of ketones with nitrobenzaldehydes in water and in poly(ethylene glycol) (PEG) were reported. It reveals that histidine is a good aldol catalyst for synthesis of β‐hydroxylketones in water and in PEG, giving good to excellent yields of the respective products. Better enantio‐ and regioselectivity were achieved using low molecular weight PEG as the media. The results show that histidine and PEG‐200 or ‐300 may constitute a promising environmentally benign system for asymmetric synthesis of β‐hydroxylketones.
