Selection of sesame mutants for higher yield and yield contributing traits through gamma ray irradiation

The experiment was conducted to observe their performance regarding seed yield and yield attributes, and to select promising mutant(s) having higher seed yield with shorter maturity periods. Five mutants along with the mother variety and one check variety were evaluated following a randomized complete block design with three replications at three sesame growing areas of Bangladesh during Kharif-I, 2017. Analysis of variance showed highly significant variations among the mutants and checks for most of the characters in individual locations and combined over locations. The mutant SM-07 produced the highest seed yield (1522 kg ha-1) at each location with taller plants and the shortest maturity period. The heatmap and correlation matrix showed a significant positive correlation among the no. of branch plant-1, no. of pod plant-1, and the seed yield. Considering mean seed yield over locations, three mutants viz., SM-07, SM-06 and SM-04 produced higher seed yield (1522, 1483 ,and 1461 kg ha-1, respectively) with took short days (83-85 days) to maturity. These three mutants need to be further zonal evaluation for conformity of their performance. Bangladesh J. Nuclear Agric, 37(1): 91-100, 2023

Promising salt tolerant soybean mutants developed through gamma ray irradiation

An experiment was conducted to evaluate the performance of three promising lines along with two check varieties of soybean in respect of plant height, branches per plant, pods per plant, seeds per pod, days to maturity and seed yield, at five different locations during January to April 2022. Significant variations were observed both in individual location and combined over locations for all traits. Among the mutants, average days to maturity ranged from 109-114 days. It indicated that, all the mutant lines as well as check varieties had prolonged days to maturity, which eventually reflected significantly higher grain yield at all locations. Plant height ranged from 34-62 cm and number of branches plant-1 from 2.9 to 3.6. Mutant SBM-22 produced highest pods plant-1 (76); whereas, the check varieties Binasoybean-2 and Binasoybean-6 produced 43 Hundred seed weight was higher in Binasoybean-2 (13.4g) and lower hundred seed weight was obtained from SBM-26 (11.1g). Seed yield obtain from the mutants and checks significantly differs from each other. Mutant SBM-25 produced the highest seed yield of 2836 kg ha-1. Among the locations, all mutants as well as check varieties gave the highest seed yield at Satkhira. Comparing with imposed salinity level and time, plant height as well as leaf was decreased. All the germinated genotypes were survived at initial salinity 4 dS m-1 (though 4 dS m-1 is not at all a problem for salinity) up to 21 days. All the mutants showed moderately tolerant at same treatment up to 7 days after sowing. Binasoybean-2, Binasoybean-6 and Lokon performed well with the advancement of time. Among the mutants SBM-22 and SBM-26 will be selected on the basis of yield contributed characters for further trials. Bangladesh J. Nuclear Agric, 37(1): 101-109, 2023

Morphological Appearance of M3 Generation Mutant Strains of Brown Rice (G16) to Support Rice Seedingi in Upland

Brown rice local cultivars are found in West Nusa Tenggara, but brown rice is still very rare to be used as a source of genetic diversity and its improvement is also lacking to be considered. This research aims to determine the effect of 300 Gy gamma ray irradiation on the quantitative properties of third generation G16 brown rice (M3) in the uplands. In this research, an experimental method was used with field experiments from May to December 2022 in Tatar Hamlet, Nyurlembang Village, Narmada District, West Lombok Regency. This research used Randomized Block Design (RBD) in an Augmented design with 18 treatments consisting of 15 G16 mutant strains and 3 comparison plants. The data obtained were analyzed using Analysis of Variance (Anova) with a level of 5%, then the real different treatment was further tested using the Least Significance Different (LSD) test. Based on the results of the research, it was obtained that some of the quantitative traits observed did not have differences in the properties of the elders and their comparators. The morphological apperance of mutant plants is the same as that of both the elders and the comparison varieties. However, it can be said that all strains based on their morphological appearance have the potential to be developed on dry land, because all strains tested show the same results compared to their elders and peers.

Antibacterial Activity against Escherichia coli and Cytotoxicity of Maillard Reaction Product of Chitosan and Glucosamine Prepared by Gamma Co-60 Ray Irradiation.

In this study, the gamma ray-induced Maillard reaction method was carried out for chitosan (CTS) and glucosamine (GA) to improve the water solubility and antibacterial activity. The mixture solution of CTS and GA was exposed to gamma rays at a dose of 25 kGy and freeze-dried to obtain a Maillard reaction product (MRP) powder. The physicochemical and biological properties of the CTS-GA MRP powder were investigated. The CTS-GA MRP powder expressed good solubility at a concentration of 0.05 g/mL. In addition, the result of the antibacterial activity test against Escherichia coli revealed that the CTS-GA MRP powder exhibited highly antibacterial activity at pH 7; in particular, bacterial density was reduced by over 4 logs. Furthermore, the cytotoxicity test of the CTS-GA MRP powder on mouse fibroblast cells (L929) showed non-cytotoxicity with high cell viability (>90%) at concentrations of 0.1-1 mg/mL. Owing to the high antibacterial activity and low cytotoxicity, the water-soluble CTS-GA MRP powder can be used as a favorable natural preservative for food and cosmetics.

Employment of collective physical pretreatment and immobilization of Actinomucor biomass for prospective crystal violet remediation efficiency

AbstractIndustrialization and urbanization have increased the number of industries that utilize colors and their wastewater, contributing to the global pollution catastrophe. Recently, wastewater treatment has relied on expensive, energy-inefficient, and limited-flexibility physico-chemical processes. This study sought a low-cost, efficient method of removing crystal violet (CVD). We created a statistical approach to choose the best practice by immobilizing physically prepared Actinomucor elegans AUMC15946 biomass. The immobilized cells displayed an enhanced CVD removal (80.3%) than the free cells (66.2%). The Box-Behnken design (BBD) was utilized at three physical pretreatment parameters (heat, UV radiation, and gamma ray) for the first time to explore and maximize the positive impact of physical parameters on the immobilized fungus efficiency for potent crystal violet removal. The maximum CVD removal (96.4%) was achieved at the following optimum conditions (45 °C of heat treatment, 20 min of UV exposure, and 300 Gy of gamma irradiation). The toxicity of the treated CVD compared to the untreated one was also evaluated via three different protocols (phytotoxicity, microbial toxicity, and cytotoxicity). The treated CVD has no any adverse effect on seed germination. Similarly, the treated dye revitalized the growth of Escherichia coli cells and two normal cell lines, epithelial breast MCF-12F and fibroblast BJ-1, compared to the untreated dye. Thus, the physically pretreated and immobilized biomass of Actinomucor is a new and potent candidate that could be applied in dye bioremediation practices.

Aqueous-Based Inorganic Colloidal Halide Perovskites Customizing Liquid Scintillators.

Compared to solid scintillators and organic liquid scintillators, aqueous-based liquid scintillators (AbLS) have more superiority in highly flexible scalability, yet are now limited by their low light yield (≈100 photons MeV-1 ). Here, aqueous-based inorganic colloidal halide perovskites with high photoluminescence quantum yield (PLQY) of three primary color luminescence up to 88.1% (red), 96% (green), and 81.8% (blue) are respectively synthesized, and a new generation of colloidal perovskite-mediated AbLS (PAbLS) with light yield increased in comparison with the commercial scintillator AbLS is fabricated. This paper exhibits that the excellent PLQY and colloidal dispersion of halide perovskites benefit from poly(ethylene glycol) modification and this modification ensures the vacancy inhibition and formation of defect-free surfaces in an aqueous solution. Moreover, their high luminescent emission can be maintained for 100 days at low temperatures, and such modification also promises the heat-to-cold customization of operating temperature even in ice below 0 °C. Finally, depending on the light yield of around 3058 and 8037 photons MeV-1 at room temperature and low temperature, PAbLS with shape/size scalability exhibit their robust radiation hardness (dose rate as high as 23 mGy s-1 ) and conceptual application potential in high-energy ray radiation detection from every angle of 360°.

Formula omitted] leaves extract mediated synthesis of reduced graphene oxide decorated nanoferrites: Structural, X-ray/gamma ray radiation shielding and optical properties

The reduced graphene oxide decorated nanoferrites (MgFe2O4, MnFe2O4, CoFe2O4, NiFe2O4, CuFe2O4, ZnFe2O4 and BaFe2O4) are synthesized via green solution combustion method using Spinach leaves as a reducing agent. The synthesized sample was characterized with different techniques. All the rGO/nanoferrites shows the planes corresponding to rGO which confirms the presence of rGO in the NCs. Except BaFe2O/rGO NCs all the nanoferrites/rGO shows the Bragg reflections corresponding to spinel cubic structure. However, BaFe2O/rGO NCs shows the orthorhombic phase with peaks corresponding to Fe2O3 and BaFe12O19. The crystallite size and other structural parameters are discussed in detail. The surface morphology consists of irregular shaped NPs on the rGO sheet. The energy band gap was determined by using Wood and Tauc’s relation. The Photoluminescence, CIE and CCT analysis clearly shows rGO/nanoferrites might be potential candidate as a blue phosphor in warm/cool Light Emitting Diodes and meet the needs of illumination devices. Further, X-ray/gamma ray interaction parameters are discussed in detail.

Effect of ultraviolet irradiation on the optical properties and biological activity of silver nanoparticles prepared by pulsed laser ablation

Silver nanoparticles (AgNPs) are vital components in nanoscience and nanotechnology, principally in nano-antibiotics and nanomedicine. This work investigates the role of ultraviolet ray irradiation on the optical properties of AgNPs prepared by the pulsed laser ablation in liquid (PLAL) technique. In this framework, Q-switched Nd:YAG laser was utilized with different laser energies (200 and 400) mJ at different numbers of pulses (100, 200, 300, 400, and 500) to generate Ag nanoparticles. UV–visible spectrometer, transmission electron microscope (TEM), and field emission scanning electron microscopy (FE-SEM) measurements were all used to characterize the samples. The UV–visible spectroscopy showed a decrease in the surface plasmon resonance (SPR) peak position and an increase in the optical band gap of AgNPs with the increase in the number of laser pulses before irradiation with UVC. TEM and FE-SEM images revealed spherical-like shapes with an average diameter range of 33–51 nm. Beyond this, antibacterial tests of both Staphylococcus aureus and Escherichia coli by AgNPs showed a slight inhibition. After UVC-irradiation times, the absorbance intensity of AgNPs and the SPR peak (411–413) nm increased; the optical band gap, however, decreased. The results of our study showed a significant inhibitory effect against both Gram (+ve) and Gram (-ve) bacteria when AgNPs were irradiated by UVC.

Effects of Gamma-Ray Irradiation of Bacteria Colonies in Animal Feeds and on Growth and Gut Health of Weaning Piglets

Animal feeds contain a substantial number and diversity of microorganisms, and some of them have pathogenic potential. The objectives of this study were to investigate the effects of different doses of gamma (γ)-ray irradiation on the bacteria count in different types of feed and then to test the effect of γ-ray-irradiation-treated fishmeal on the gut health and growth performance of weaning piglets. In trial 1, three fishmeal samples, two feather meal samples, three meat meal samples, three soybean meal samples, and three vitamin complexes were treated with γ-ray irradiation doses of 0, 3, 6, or 9 kGy. The 6 and 9 kGy doses eliminated most of the bacteria in the feed but also resulted in a loss of vitamin C and B1. In trial 2, 96 weaning piglets were fed one of the following three diets with eight replicates (pens) per group over a 14-day period: (1) the control diet—the basal diet supplemented with 6% fishmeal with a low bacteria count (40 CFU/g) and no E. coli; (2) the fishmeal-contaminated diet (FM-contaminated) diet—the basal diet supplemented with 6% fishmeal with a high bacteria count (91,500 CFU/g) and E. coli contamination; and (3) the irradiated fishmeal (irradiated FM) diet—the basal diet supplemented with γ-ray-irradiation-treated E. coli-contaminated fishmeal. The piglets that received the FM-contaminated diet had significantly lower average daily gain and a greater diarrhea index compared to those fed the control diet, whereas γ-ray irradiation treatment abrogated the negative effect of the E. coli-contaminated fishmeal. Collectively, γ-ray irradiation at a dose of 6–9 kGy was sufficient to eliminate the microorganisms in the feed, thereby benefitting the growth performance and gut health of the weaning piglets.

Meiotic analysis of induced translocation heterozygotes in Lepidium sativum Linn.

Aim: To assess the cytological effects of Gamma rays on the pollen mother cells and post meiotic products of Lepidium sativum Linn. which resulted in isolation of translocation heterozygote and aneuploid gametes. Methodology: During the experiment, parameters such as Meiotic stages, chromosomal structure, and pollen fertility were studied. Fresh seeds of Garden cress were orderly arranged in plastic and divided into four groups. The fresh seeds of each group were individually irradiated with 60Gy, 150Gy, 300Gy, 450Gy and 600Gy @ 7.247KGyh-1 in the Floriculture Laboratory of National Botanical Research Institute (NBRI), Lucknow (India). The source for gamma ray irradiation was Cobalt-60. The irradiated seeds were sown in triplicates along with their respective controls. Results: Meiotic analysis of pollen mother cells (PMCs) at 300Gy showed translocation heterozygotes, however, in the control sets, the rate was negligible and phenotypically the plants were weak and short heighted. The cytological illustration of chromosomal configuration at diakinesis and metaphase I exhibited the superiority of tetravalents, bivalent and other forms of chromosomal associations such as multivalents. The induced translocation heterozygotes resulted in stickiness at metaphase and anaphase states along with the formation of bridges at anaphase stage. Due to chromosomal anomalies, the pollen fertility was reduced to 37.54±0.25% in contrast to control plants (98.20±0.16%). Interpretation: The current research work would be of paramount interest as translocation heterozygote serves as a source for raising aneuploid offspring having novel genetic combinations. Key words: Chromosomal anomalies, Heterozygotes, Lepidium sativum Linn, Meiosis, Pollen fertility

Study of gamma radiation shielding on tellurite glass containing TiO2 and Al2O3 nanoparticles

Radiation shielding incorporates material between the radioactive source and environment to decrease exposure to hazardous radiation. It remains to be seen whether the addition of nanoparticles effectively increases the protection of tellurite glass system from further degradation under irradiation conditions. This study revealed the gamma radiation effects on tellurite glass. The tellurite glass samples were irradiated with 50 kGy and 100 kGy gamma ray, and subsequently analysed using X-ray diffractometer (XRD), atomic force microscopy (AFM), and ultraviolet–visible spectroscopy (UV–Vis). Gamma radiation increased the creation of non-bridging oxygen (NBO) and caused colour change on TZNETi and TZNETiAl glasses. Consequently, the addition of aluminium oxides (Al2O3) was found to lower the density of glass systems. The glass samples surface roughness increased, while the optical transmission spectra decreased after 50 kGy of gamma ray irradiation. Nevertheless, the glass system maintained its transparency even after irradiation. The mass attenuation coefficient (MAC) values represented the shielding effectiveness demonstrated by the investigated glass with the addition of Al2O3. The physical, structural, optical, and radiation shielding properties showed that 69.1TeO2–20ZnO–9Na2O–1Er2O3–0.3TiO2–0.6Al2O3 (TZNETiAl) sample exhibited strong shielding properties amongst the fabricated tellurite samples.

Non-gravitational Mechanism of Comets’ Ejection from the Oort Cloud Due to Cometary Outbursts

Cometary nuclei located in the Oort cloud accumulate high concentration of radicals in surface layers under cosmic ray irradiation at low temperatures. Recombination of radicals induced by an increase in the surface temperature of a comet by a close passing star, O/B stars, or nearby supernovae leads to the heating of the ice layer with the releasing of volatiles from the amorphous ice. When high gas pressure builds up beneath the cometary surface, dust and gas are ejected. The resulting jet of gas and dust can change the comet’s orbit in the Oort cloud. The studied non-gravitational mechanism can effectively expel comets with a radius of ≤1 km from the Oort cloud into the inner part of the Solar system. The total effect of cometary outbursts on the stability of cometary orbits during the evolution of Solar system can result in a decrease in the number of long-period small-radius comets.

Improvement Of The Structural And Chemical Properties Of An Activated Carbon Derived From Date Stems By KOH-Activation Using Gamma Ray Irradiation

Radiation-Induced De Novo Defects in Metal-Organic Frameworks Boost CO2 Sorption.

Defects in metal-organic frameworks (MOFs) can significantly change their local microstructures, thus notably leading to an alteration-induced performance in sorption or catalysis. However, achieving de novo defect engineering in MOFs under ambient conditions without the scarification of their crystallinity remains a challenge. Herein, we successfully synthesize defective ZIF-7 through 60Co gamma ray radiation under ambient conditions. The obtained ZIF-7 is defect-rich but also has excellent crystallinity, enhanced BET surface area, and hierarchical pore structure. Moreover, the amount and structure of these defects within ZIF-7 were determined from the two-dimensional (2D) 13C-1H frequency-switched Lee-Goldburg heteronuclear correlation (FSLG-HETCOR) spectra, continuous rotation electron diffraction (cRED), and high-resolution transmission electron microscopy (HRTEM). Interestingly, the defects in ZIF-7 all strongly bind to CO2, leading to a remarkable enhancement of the CO2 sorption capability compared with that synthesized by the solvothermal method.

Katokkon chili is local horticultural commodity originating from Toraja and is often called katokkon pepper. This chili has good adaptation with a fairly high yield. The people of Toraja and the surrounding area really like this type of chili because it has one of the advantages of a production period that is not too long, around 3-4 months after transplanting. The purpose of this study was to determine the effect of giving a dose of gamma ray irradiation on the genetic parameters of katokkon chili plants. The use of this research as a basis for developing and improving genetics in breeding katokkon chili plants eith a dose of gamma irradiation. The implementation of the research was carried out at BTP. Tamalanrea, Tamalanrea District, Makassar City, South Sulawesi and the Integrated Farming System Education Garden, on Jl. Raya Poros Sappaya, Bontoramba Village, Pallangga District, Gowa Regency, from March to July 2023. The plants came from the control treatment (D0) and 200 Gray (D1) consisted of 3 replicates for each treatment and each experiment consisted of 15 plants, so that the total number of plants in this study was 90 plants. The research was carried out in the form of a randomized block design (RBD) with a dose of gamma irradiation as the main factor. The results showed that gamma irradiation at doses of 200 Gray could have a genetic effect compared to D0 on flowering age, number of fruit planted, fruit diameter, fruit weight, fruit stalk diameter, fruit length and fruit flesh thickness.

Comparative study of electron beam and gamma ray irradiation effects in RPC glass detector materials by positron lifetime spectroscopy

This work is intended to compare the electron beam and gamma ray irradiation induced microstructural effects and electrical conductivity in glass Resistive Plate Chamber (RPC) detector materials with different doses. Positron annihilation lifetime spectroscopic (PALS) technique was used to analyze the irradiation induced structural modifications in the RPC detector materials. PALS analysis at lower doses indicates the increased void size with the creation of additional sites in the glass network upon both the irradiation sources. At higher irradiation doses, the reduced void size shows the enhanced chemical bonding between the tetrahedral sites of Si-O-Si and hence increases the short range order in the silica glass. The variation of DC conductivity upon both the irradiation techniques correlates well with the measured void size. Gamma ray irradiation produced more structural changes in the glass samples as compared to the electron beam irradiation.

Gamma irradiation of eggplant seeds influences plant growth, yield and nutritional profile in M1 generation

The study examines agromorphological traits and nutrient compositions in three genotypes of eggplants (Solanum melongena ‘African Beauty F1’ and ‘Melina F1’ and S. aethiopicum ‘Kotobi’) grown from seeds irradiated by gamma rays (γ-ray) with 100 Gy. Experiments were carried out in the screenhouse and experimental field of Crop Science Department, University of Calabar, Nigeria. Completely randomised design with four replications and randomised complete block design with three replications was used in the screenhouse and field experiments respectively. Eggplant × γ-ray effect reduced (p ≤ 0.05) seedling emergence, plant height and number of leaves in the nursery at 2 and 4 weeks after sowing. In the field, these traits were consistently lower for irradiated Melina F1 and Kotobi (p > 0.05) at ten weeks after transplanting. Irradiated African Beauty F1 had the highest (p ≤ 0.05) upper canopy leaf area (429.54 cm2), higher (p > 0.05) plant height and stem width; lower (p > 0.05) number of branches and leaves. Un-irradiated and irradiated Kotobi had the highest (p ≤ 0.05) fruit load, lower (p ≤ 0.05) fruit volume, weight and yields over four harvest intervals. Carbohydrate and energy contents of Kotobi fruits grown from 100 Gy gamma-ray irradiated seeds were concurrently improved (p ≤ 0.05). Gamma ray irradiation had both positive and negative influences on the agromorphological traits, mineral composition and nutrient profile of eggplants. However, 100 Gy dose of irradiation had a negative effect on fruit characteristics in general. From the results of this study, inconsistent variations in the agromorphological traits of the irradiated eggplants of the three varieties were reported. Therefore, the goal of mutation breeding in eggplant should not undermine the importance of the eggplant genotype as well as the actual radiation dose.

A comparative study of UVA and UVB radiation: Mechanisms of DNA damage and repair

Ultraviolet (UV) radiation, comprising UVA and UVB rays, poses a significant threat to human health. This review aims to elucidate the differences between UVA and UVB radiation in their ability to induce DNA damage, shedding light on the underlying molecular mechanisms involved. Understanding these mechanisms is crucial for developing strategies to mitigate the harmful effects of UV radiation. The study analyzed histological changes in UVA and UVB-exposed skin and explored matrix metalloproteinases (MMPs) and reactive oxygen species (ROS) in UV-induced skin damage. It examined DNA lesions caused by UVA and UVB radiation. UVA radiation led to dermal integrity loss, collagen breakdown, and inflammatory infiltration, while UVB radiation primarily resulted in keratinocyte proliferation. UVA-induced MMP activation accelerated collagen breakdown, whereas UVB exposure moderately increased MMP activity. UVA caused more DNA and protein oxidation, while UVB primarily induced oxidative protein modification and endoplasmic reticulum (ER) stress. UVA-induced oxidative stress and DNA damage were associated with skin cancer, premature aging, and immune suppression. UVB radiation directly interacted with DNA, forming cyclobutane pyrimidine dimers (CPDs) and pyrimidine (6-4) pyrimidone photoproducts (6-4PPs), which are strongly associated with skin cancer development. UVA and UVB radiation have distinct characteristics and induce different DNA lesions. Repair mechanisms, such as nucleotide excision repair (NER) and base excision repair (BER), play crucial roles in maintaining genomic integrity. Understanding the mechanisms underlying UVA and UVB-induced DNA damage and repair is essential for developing targeted prevention and therapeutic approaches to combat the harmful effects of UV radiation.

Effect of gamma rays irradiation in the structure, optical, and electrical properties of samarium doped bismuth titanate ceramics

AbstractCeramics have enormous potential in several emerging technologies, including nuclear reactors. Materials with chemical inertness, high-temperature operation, and physical properties stability under applied radiation with high energy are all desired in this field of technology. Given these broad specifications, bismuth titanate ceramics may prove to be a valuable material. Regarding this task, the effect of gamma rays on the structural, optical, and ferroelectric properties of samarium-modified bismuth titanate ceramics was investigated. The Bi3.15Sm0.85Ti3O12(BSmT) compound was irradiated for 0, 50, 100, and 200 kGy using a60Co gamma source at a dose rate of 10 kGy h−1. The phase structure confirmed the orthorhombic, single-phase nature even after gamma irradiation. The results show that the unit cell volume decreases from 966.39 to 962.38 Å3with an increase in gamma dose from 0 to 200 kGy. The X-ray photoelectron spectroscopy study shows an irradiation-induced defect in the host matrix. The results show that the bandgap energy, dielectric constant, Curie temperatures, and remnant polarization slightly decreased with an increase in gamma irradiation. According to the findings of this study, the BSmT exhibits adequate stability against gamma irradiation, which offers tremendous promise in their utilization in nuclear reactor technology.
