Attribute Based Encryption Techniques of Cloud Computing Access Control
Authors: - Deepali Madan Adhav , - Mallikarjun M. Math
Published: March 2024

Cloud computing has emerged as a transformative development in the realm of Information Technology. The advent of services like "on-demand" and "pay-as-you-go" has led to the migration of both government and industrial IT infrastructures up in the clouds. With data and business logic being stored on remote cloud servers, the security concerns connecting to the cloud environment differ from those of traditional computing. In the domain inside cloud computing, data security is administered by Cloud Service Providers (CSPs), leaving owner of the data with limited control over the security policies governing their own data. Privacy and saftey stand out as two critical factors that discourage users from transitioning to untrusted cloud environments. Despite the substantial savings in costs associated with cloud adoption, ensuring secured data sharing consistently remains a top priority for data owners. As a result, these two aspects demand heightened attention to facilitate securely sharing data within the cloud computing landscape. This paper undertakes a comprehensive review and comparison of various attribute-based encryption schemes within the context of cloud computing.

Published: March 2024

The geochemical distribution of several trace metals (lead (Pb), cadmium (Cd), copper (Cu), zinc (Zn), nickel (Ni), chrome (Cr), cobalt (Co) and iron (Fe)) was investigated using five sequential extraction procedures to provide information on their distribution and environmental impacts on the Iraqi coastal sediments. Sediment samples were collected from 16 sites along the coast to determine the concentrations of the above metals. The concentration and ratios of these metals were estimated in the sediment extract (concentration on the exchange surfaces, carbonates, manganese oxides and iron oxides, organic matter and those associated with the remainder) using extraction methods (magnesium chloride, 1 molar of sodium acetate, 0.5 molar of hydroxylamine hydrochloride, 0.2 molar of ammonium oxalate, concentrated nitric acid and 25% of hydrofluoric acid) to extract and separate the above fractions in order. The results indicated that the total sediment content of Pb and Cd were higher than their rate of occurrence in the crust, while copper, zinc, nickel, chrome, cobalt and iron were within those limits. According to the I-geo the metals Cr, Cu and Zn are considered at unpolluted class while Ni and Pb were ranged from moderately to strongly level. On the other had Cd was found at extremely level as its I-geo exceeded the highest-class value. These metals are bonded to different power bonds. Pb, Cr and Co have dominant in exchangeable and carbonates fraction. Iraqi tidal flats is characterized by very high risk considering Cr, Pb, Co and Cu which represented by RAC values, so they can move to the solution to become available for living.

Dietary intake of contaminated food with heavy metals may cause severe risk for the human health. Heavy metals affect adversely a human health. The current study assessed the concentrations of heavy metals including Cu, Zn, Pb and Ni in eggplant (Solanum melongena L.) of urban and rural areas in Bangladesh. The experimental samples of fresh eggplant fruits were collected from six local markets in Jashore, Bangladesh, and the tissues were extracted with nitric acid and hydrogen peroxide. Trace elements in eggplant fruits were estimated with atomic absorption spectrophotometer. Obtained result show that Heavy metal concentrations were high in the urban areas compared to rural areas.  Heavy metals in the eggplant fruits of rural and urban areas were: Pb (2.74-18.64), Cu (10.20-67.16), Ni (46.63-148.46), and Zn (86.65-148.73) mg.kg-1 respectively. The concentrations of Pb, Ni and Zn in eggplant were at an excess of safe limits according to the Food and Agriculture and World Health Organizations. While, Cu was lower than the maximum safe limit. The present study concluded that growing eggplants in Jashore areas are heavily contaminated with Pb, Ni and Zn that would be hazardous for consumer’s health. The result of this study will be beneficial for the agricultural policy makers in Bangladesh to take appropriate action and reduce the heavy metal toxicity among fresh food products.

Published: March 2024

Cucumis melo var inodorus cv. Manis Terengganu is known as Terengganu’s iconic fruits. However, MMT production is still insufficient to satisfy local demand. Over-reliance on chemical fertilizers to MMT has reduced soil fertility, degraded soil quality resistance, and negatively affected the environment. As a result, efficient microorganisms such as Paenibacillus alvei and Bacillus toyonensis were investigated as possible ecologically compatible biofertilisers for MMT. In this study, B. toyonensis and P. alvei produced indole-3-acetic acid (IAA) at concentrations of 20.49 µg.mL-1 and 19.18 µg.mL-1, respectively. hen, the greenhouse testing was conducted to evaluate the potentiality of effective microbes as plant growth promoter rhizobacteria by introducing the soil with B. toyonensis, P. alvei, and consortium. The experiment was laid out in a randomized complete block design (RCBD) with three groups of bacteria plus the control and each treatment replicated 15 times. Data were analyzed according to ANOVA procedure. As a result, B. toyonensis, P. alvei, and consortium significantly increased in all experimental growth parameters such as plant height, leaves, chlorophyll content, root mass, root length, leaf area, fruit weight, macronutrients, and micronutrients compared to control. Overall, the results showed that the effective single microbial strains promoted the development of MMT more effectively than the consortium

Published: March 2024

A field experiment was conducted at the University of Baghdad, Al-Jadriya in the spring season of 2021 for the potato crop under the influence of organic biofertilizers and water stress. Three levels of bio-organic fertilizers were used 0 (OM0), 1 (OM1) and 1.5 (OM2) ton ha-1 and three levels of irrigation 30 (I-30), 50 (I-50) and 75 (I-75) % water depletion were available to evaluate the role of bio-organic fertilizer and water stress in production functions and water use efficiency. I-30 treatment showed the highest water consumption ranging between 468 and 486 mm season-1 and decreased to 355-436 mm with water stress treatments I-75. The values of water consumption varied according to the levels of bio-organic fertilizer. The percentage of decrease in water consumption was 1.49 and 3.66% at low stress and reached 6.37% at high stress (I-75) compared to OM0. Both treatments I-30 and I-50 gave the same yield. Bio-organic fertilization led to an increase in the average yield of tubers 32.8 and 41.9% for both OM1 and OM2 compared to OM0. The production functions indicate that the yield increases by 0.057 ton ha-1 mm-1 of added water, and the water depth must be greater than 64.2 mm to obtain a yield that is 1.96 ton ha-1 more (significant limit) than the treatments in the experiment (1.96=0.057(Irr.). )-1.70). Fertilizer levels are higher than 1.9 ton ha-1 to obtain a higher yield of tubers by 26.29 tons/ha and the efficiency of water use is nil according to the water use function when the water consumption is higher than 692.7 mm. The response factor decreased when adding bio-organic fertilizer compared to OM0, which means that plants were not affected significantly under water stress conditions.

Published: March 2024

In recent years, nanotechnology has emerged as one of the promising new technologies for pest control. In this study, a screening program was conducted to evaluate the impact of silicon nanoparticles (SiNPs) and silver nanoparticles (AgNPs) on the mortality of the adult stage of Tribolium castanium on wheat grains. The nanoparticles were synthesized using a laser ablation process, and their characterization was performed using Zeta-sizer, UV-visible spectroscopy, X-ray Diffraction, and Transmission Electron Microscopy. Different concentration levels of SiNPs and AgNPs (100 ppm, 200 ppm, 300 ppm, and 400 ppm) were tested to assess their effects on T. castaneum mortality. The LC50 value for SiNPs and AgNPs were calculated at 438.3 and 657.4 ppm NPs, respectively. The feeding method revealed that AgNPs resulted in 40% mortality, while SiNPs resulted in 70% mortality. These findings suggest that the synthesized SiNPs have a greater potential as an alternative option in managing pests in stored products compared to AgNPs at the same exposure time (four days). The results showed that both SiNPs and AgNPs were having a potential effect on adult stage of T. castaneum. This study demonstrated the utility of AgNPs and SiNPs in T.castaneum pest management programs.

This study aimed to investigate the tolerance level and the use of primers (H2O, KNO3, ascorbic acid and salicylic acid), in mitigating stress in maize in the newly released cultivars (SWAN-LSR-Y, BR9928-OMR-SR-Y and OMR-LSR-SY). Activities of SOD, APX, CAT and GSH and lipid peroxidation were investigated, to measure the biochemical response of the primed maize seeds. Maize seeds primed with KNO3 and ascorbic acid improved germination and anti-oxidative potential against ROS in ameliorating the salinity stress, while salicylic acid slowed germination. The same trend was followed in the seed vigour index and radicle length of seeds primed with ascorbic acid, which recorded the highest values. The control was observed to have the highest seed vigour index, while seeds primed with salicylic acid showed the least vigour index in the maize seeds.  Increased salinity stress showed adverse effects on all growth parameters. Of the maize cultivars tested, SWAN-LSR-Y showed the most tolerance to salinity stress, in terms of germination. Significant high enzymatic activities and lipid peroxidation were recorded in seeds primed with ascorbic acid and KNO3 show their importance in plant metabolic activities.

Published: March 2024

A laboratory experiment was conducted to study zinc adsorption at eight concentrations (0, 25, 50, 100, 150, 200, 250 and 300 mg L-1) by using ZnSO4.7H2O. with two replicates were used for each concentration, where 20 mL of zinc solution was added to 1 gram of natural zeolite, synthetic zeolite, soil 1, and soil 2. Langmuir equation was used to describe the relationship between zinc adsorption and its concentration. Additionally, the Freundlich equation was used to describe adsorption of ions. Freundlich equation was found to be more important than Langmuir equation, as the values of k and b in Freundlich equation and the R2 values for natural and synthetic zeolites were higher in both soils. The second experiment involved kinetics. Zeolite and soil were kept moist at field capacity throughout the incubation period. Zinc was extracted using DTPA after each incubation period, with two replicates to study the rate of zinc release from zeolite and soil over time and its concentration in the solution. results showed a decrease in the availability of added zinc with increasing incubation time. The highest concentration of available zinc was found when zinc was added to synthetic zeolite, reaching 346 µg Zn+2 ml-1 at the end of the incubation period. The second-order equation was the most effective in describing the behavior of zinc and its reaction rate during the incubation period, representing the period of crop growth.

An outdoor pots experiment was conducted at agricultural research station, University of Basrah, southern Iraq (30°34'4.80" N 47°44'56.40" E) during winter season of 2021-2022. The study was carried to reveal the effect of Nano phosphate fertilizer compared to superphosphate fertilizer on growth parameters of two wheat cultivars (Triticum aestivum L.). Superphosphate fertilizer was added at rates of 0, 30, 60 and 90 kg p ha-1, while, Nano phosphate source was applied at 0, 3, and 6 kg P. ha-1. Two wheat cultivars (Jad and Adina) were used. Both P sources were mixed with pot soils at planting time. Wheat plants were grown for 70 days period. Plant parameters: tillers numbers, plant high, leaves number, flag leaf area, dry weight, P concentration were obtained at harvest time. Phosphorus uptake was calculated at same time. Results of the study showed that there was no significant differences in all studied growth parameters between superphosphate and Nano phosphate sources, even though the rate of applied Nano phosphate source were much lower than that of superphosphate source. The results also indicated that, irrespective of the origin of phosphorus, higher rates of applied phosphorus led to an increase in all the growth parameters examined. When comparing the two phosphorus sources and their application rates, most growth parameters for the Adina cultivar exceeded those of the Jad cultivar at both phosphorus sources applied rates. Additionally, the results highlighted a significant interaction among treatments for all the investigated growth parameters.

Local black goat are raised for the purpose of milk production. The goal of the current study was to identify the growth hormone gene's single nucleotide polymorphism (SNPS). Additionally, the effect of the GH gene SNP on the milk qualities of Iraqi black goat was evaluated.  DNA was extracted from blood samples of 28 goat. A segment with a length of 330 bp in the third intron and the fourth exon of the GH gene was analyzed. Bioinformatics software was used to analyze the results. The results showed the presence of three genotypes (TT, TC, CC) at position 263 of the studied plot with a frequency of 0.36, 0.21, and 0.43, respectively. The local breed was characterized by a decrease in observed heterozygosity (21.43%). However, the expected heterozygosity was 50.65%. Low heterozygosity may indicate the presence of inbreeding within the same herd. Haplotypes network revealed a genetic relationship between the local Iraqi goat and the Egyptian goat. As well as the existence of a genetic relationship at a lower level with the Indian goats. From Tajima's D test and Fu's Fs (1.547 and 1.428), the results led to a rise in inbreeding. In milk production, energy, and the amounts of protein. The analysis of the data using bioinformatics tools predicted the effects of identified the genotypes in which the amino acid was not altered, and this is where the mutation was found. There is a relationship between the genetic polymorphism of the growth hormone gene and the production of milk and its components. The CC genotype was superior in milk production, energy, and the amounts of protein and fat over the TC and CC combinations.
