A study on the interaction parameters of charged and uncharged radiation types with some indoor plants

This study investigates how gamma rays, neutrons, and electrons interact with five commonly found indoor plants: Spathiphyllum wallisii (SW), Ficus elastica (FE), Dieffenbachia camilla (DC), Schefflera arboricola (SA), and Ficus benjamina (FB). Utilizing experimental measurements (with HPGe detector), Monte Carlo simulations (GEANT4 and FLUKA), and theoretical calculations (ESTAR and WinXCOM), some radiation interaction parameters for gamma rays, fast neutrons, thermal neutrons, and electrons were determined. Secondary particle generation was also analyzed to provide a comprehensive assessment. The determined linear attenuation coefficients with the help of the WinXCOM are 0.1376, 0.1662, 0.1385, 0.1651 and 0.1698 cm−1 for SW, FE, DC, SA and FB, respectively. The calculated total macroscopic cross sections for indoor plants in the same sample order are 2.0290, 2.0350, 2.0285, 2.0363 and 2.0362 cm−1. Among the investigated plants, FB exhibited the highest gamma ray interaction, while SA and FB showed superior interaction against fast neutrons compared to SW and DC. The findings reveal significant variations in interaction effectiveness and secondary radiation production across these plants, offering valuable insights for radiation safety and environmental health evaluations.

Evaluation of plant growth and spacing effects on bioengineered slopes subjected to rainfall

Shallow landslides can be mitigated through the hydro-mechanical reinforcement provided by vegetation. Several critical parameters, such as plant spacing and plant age, play a significant role in influencing bioengineered slope stability facilitated by vegetation. However, the coupling of these effects on the stability of vegetated slope has been ignored. The objective of this study is to investigate the hydro-mechanical impact of vegetation growth and spacing on the stability of bioengineered slopes based on the predictions of a calibrated numerical model against field measurements. The impact of vegetation is investigated, with specific attention given to different plant spacing and growth stages, utilizing Schefflera arboricola. In the context of rainfall, it was observed that younger vegetation demonstrated more effective matric suction retention and recovery up to 25 kPa compared to the aged vegetation. Vegetation was revealed to substantially enhance the factor of safety up to 0.3 compared to the bare slope. Plant growth and reducing plant spacing increased the impact of root systems on both hydraulic and mechanical stability, primarily attributable to the influence of root cohesion rather than transpiration rates. The results revealed that the mechanical contribution to the factor of safety enhancement was raised from one-third to two-thirds because of the vegetation-induced cohesion within the growing rooted zone.

Schefflera arboricola Tablets Relieve Diabetic Neuropathic Pain: Involvement of Oxidative Stress and Inflammation

Background Diabetic neuropathic pain (DNP) is a serious chronic complication of diabetes mellitus. Oxidative stress and inflammation are considered the central mechanisms of its pathogenesis. Schefflera arboricola (SA) is a Schefflera plant of the Araliaceae family that has the effect of pain relief. In this study, the effect of SA on DNP was first investigated. Materials and Methods Diabetic neuropathy in rats was induced by a single injection of streptozotocin (60 mg/kg). Three weeks later, SA (100 mg/kg, 300 mg/kg) or gabapentin (100 mg/kg) was given once a day for a week. Blood glucose, body weight, and thermal withdrawal latency in DNP rats were measured. The morphology of the sciatic nerve was observed by light microscopy and toluidine blue staining. Semiquantitative analysis of myelin basic protein (MBP) of the sciatic nerve was performed by immunohistochemistry. IL-1β, tumor necrosis factor-alpha (TNF-α), and IL-6 were detected by enzyme-linked immunosorbent assay. Commercial reagent kits were used to detect inducible nitric oxide synthase, superoxide dismutase (SOD), and malondialdehyde (MDA). The expression levels of nuclear factor erythroid-2-related factor 2 (Nrf2) and nuclear factor-kappa B (NF-κB) were detected by Western blot. Results DNP rat model was successfully constructed. SA and gabapentin could alleviate the thermal sting pain of DNP rats, increase the expression of MBP and SOD, and decrease the expression of proinflammatory agents and MDA. Moreover, SA could reverse the upregulation of NF-κB and the downregulation of Nrf2. Conclusion SA has a significant protective effect on DNP, manifesting in the improvement of allodynia and sciatic nerve pathology, inhibition of neuroinflammation, reduction of oxidative stress, enhancement of Nrf2, and inhibition of NF-κB.

Constrained temperature and relative humidity predictive control: Agricultural greenhouse case of study

The importance of Model Predictive Control (MPC) has significant applications in the agricultural industry, more specifically for greenhouse’s control tasks. However, the complexity of the greenhouse and its limited prior knowledge prevent an exact mathematical description of the system. Subspace methods provide a promising solution to this issue through their capacity to identify the system’s comportment using the fit between model output and observed data. In this paper, we introduce an application of Constrained Model Predictive Control (CMPC) for a greenhouse temperature and relative humidity. For this purpose, two Multi Input Single Output (MISO) systems, using Numerical Subspace State Space System Identification (N4SID) algorithm, are firstly suggested to identify the temperature and the relative humidity comportment to heating and ventilation actions. In this sense, linear state space models were adopted in order to evaluate the robustness of the control strategy. Once the system is identified, the MPC technique is applied for the temperature and the humidity regulation. Simulation results show that the regulation of the temperature and the relative humidity under constraints was guaranteed, both parameters respect the ranges 15 °C ≤ Tint ≤ 30 °C and 50 % ≤ Hint ≤ 70 % respectively. On the other hand, the control signals uf and uh applied to the fan and the heater, respect the hard constraints notion, the control signals for the fan and the heater did not exceed 0 ≤ uf ≤ 4.3 Volts and 0 ≤ uh ≤ 5 Volts, respectively, which proves the effectiveness of the MPC and the tracking tasks. Moreover, we show that with the proposed technique, using a new optimization toolbox, the computational complexity has been significantly reduced. The greenhouse in question is devoted to Schefflera Arboricola cultivation.

Fruit Peel Soil Supplementation Induces Physiological and Biochemical Tolerance in Schefflera arboricola L. Grown Under Heat Conditions

Schefflera plant is propagated and grown under greenhouse cultivation, and most of these greenhouses are low-cost. In the summer, the heat generated in greenhouses becomes a limiting factor for plant growth and, subsequently, limits the production of high-quality species under greenhouse conditions. The powder of banana (B), orange (O), and pomegranate (P) peels and their combinations were added as soil supplementation at rates of 8 and 16 g/pot to the pots of Schefflera plants, which were grown during the summer season under a low-cost greenhouse. The growth analysis was estimated after 150 and 180 days from planting. Heat conditions significantly inhibited the relative growth rate, crop growth rate, and absolute growth rate (AGR) of Schefflera plants, but fruit peel applications were shown to markedly mitigate its negative impact. Fruit peel applications augmented the shoot and root growth rates and leaf pigments, decreased AGR reduction, promoted relative water content, increased membrane stability index (MSI), and alternated the phenotypic plasticity index (PPI). Fruit peels significantly increased total phenol and flavonoid levels as well as the antioxidant activity (DPPH), which positively alleviated the oxidative damage (decreased H2O2 and MDA contents) that occurred in plant leaves, and induced heat-shock protein synthesis, leading to plants with greater heat tolerance. Orange peel application at the rate of 16 g/pot to the potting soil is more beneficial for root initiation and development during the early phases of Schefflera plant life, as well as more effective in increasing the aerial portions and inducing resistance to heat conditions in low-cost polyethylene greenhouses.

Seasonal variations of dustfall fluxes and biochemical parameters in the foliage of selected indoor plants in Delhi, India

This study reports the seasonal variations in dry deposition of coarse and fine particles on the foliar surfaces of common indoor plants viz. Ficus elastica, Ficus lyrata, and Schefflera arboricola along with their biochemical changes in the urban households of metropolitan Delhi. The dustfall fluxes were significantly higher at the industrial site as compared to residential site and temporal variations indicated higher dustfall fluxes during the winter months as compared to other seasons. Seasonal concentrations of chlorophylls, pH, and soluble sugars were higher during monsoon season for the indoor plants whereas ascorbic acid content was higher in the winter season indicating more stress. The results of correlation plots revealed that the variations observed in the biochemical traits were interlinked with the changes in dustfall fluxes during different seasons, thereby reflecting the changes in air pollution stress faced by plant foliage. The air pollution tolerance index and anticipated performance index were evaluated to understand the overall tolerance of indoor plants toward air pollution which can be utilized in phytoremediation techniques. It was concluded that among the studied indoor plants, Ficus elastica and Ficus lyrata are better plant species than Schefflera arboricola for improving indoor air quality.

Effect of different hormones on rooting development of Schefflera arboricola plants

The use of rooting hormones is important and appropriate for the rooting of Schefflera arboricola. This study was conducted at Palestine Technical University, Kadoorie (PTUK) in 2020 to find out the optimum hormone rooting on the cuttings of Schefflera arboricola. Three treatments with four replicates were used in a fully randomized system. Compared to the regulated cuttings, all the used hormones improved rooting. In most cases best rooting results were obtained with Schefflera arboricola cutting treated with T8 powder as follows: the effect of T8 hormone average values for the three stages (i.e., after 15, 23 and 30 days) were 8.5, 12.5 and 18.1 g, respectively, while for CFP gel hormone values were 3.3, 6.1 and 9.6 g, compared to the control values 1, 1.8 and 3.7 g. It could be concluded that the powder hormones were more efficient than the liquid ones.

GROWTH RESPONSE OF INDOOR ORNAMENTAL PLANT SPECIES TO VARIOUS ARTIFICIAL LIGHT INTENSITIES (LED) IN AN INDOOR VERTICAL GARDEN

Urban population spends most of their time indoors leading to multiple problems. Making an indoor vertical garden and associating people to this new concept will help build the indoor environment with improved energy efficiency, indoor air quality, their improved health and well-being. Of all of the factors affecting plant growth in interiors, adequate light is by far the most important. LED is an efficient, energy-saving light source widely used in artificial light plant production systems. Lack of scientific information regarding the light intensity requirement for optimum growth of the indoor ornamental plant species under Indian conditions makes the study of utmost importance. Five indoor ornamental plant species namely, Schefflera arboricola, Dracaena godseffiana, Philodendron salloum, Syngonium podophyllum and Scindapsis aureus were planted in pots (5”) with soil less media arranged as vertical structures (6?11”x4?3”) aligned to interiors walls of a room. Four such structures/frames were fabricated, fertigated with 100 % of the Hoagland solution and artificially illuminated using LED lighting system (PWM controlled) with different light intensities i.e. 700-1100 lux (LI I), 1100-1500 lux (LI II), 1500- 1900 lux (LI III) and LI IV had no artificial light illumination (control). From the most effective positive response of plant species under study on the basis of their growth response towards different light intensities, it was concluded that Philodendron salloum responded best to LI I (700-1100 lux), Scindapsis aureus to LI II (1100-1500 lux), Dracaena godseffiana, Schefflera arboricola and Syngonium podophyllum to LI III (1500-1900 lux).

Relationship between matric suction and leaf indices of Schefflera arboricola in biochar amended soil

Stomatal conductance (SC) and chlorophyll concentration (CC) are sensitive to soil matric suction (ψ). The relationship between these two plant parameters and ψ in the root zone can help understand the water uptake efficiency and photosynthetic capacity of a plant. This paper aims to quantify the relationships between SC and CC with ψ, for Schefflera arboricola grown in compacted bare silty sand and biochar amended soil (BAS). Plant parameters (SC, CC, leaf area (LA), root length (RL)) and ψ were regularly monitored in an atmospheric controlled room. The maximum recorded SC was greater in BAS than that in bare soil due to the higher water demand of LA. Based on measured data upon evapotranspiration, two equations are proposed to interpret the effects of ψ on plant water uptake and photosynthesis. A fitting equation is established to relate normalized SC with ψ to identify a threshold suction ([Formula: see text]; indicator of drought stress resistance). The magnitude of [Formula: see text] is found to be mainly dependent on LA/RL ratio and root ends. Furthermore, a new relationship between CC and ψ is observed and developed. A decrease in CC at higher ψ is attributed to leaf senescence and stomatal closure, restricting plant to produce more chlorophyll.

Artificial neural network classification of foliage targets from spectrograms of sequential echoes using a biomimetic audible sonar

Classifying foliage targets using echolocation is important for recognizing landmarks by bats using ultrasonic emissions and blind human echolocators (BEs) using palatal clicks. Previous attempts to classify foliage used ultrasonic frequencies and single sensor (monaural) detection. Motivated by the echolocation capabilities of BEs, a biomimetic sonar emitting audible clicks acquired 5600 binaural echoes from five sequential emissions that probed two foliage targets at aspect angles separated by 18°. Echo spectrograms formed feature vector inputs to artificial neural networks (ANNs) for classifying two targets, Ficus benjamina and Schefflera arboricola, with leaf areas that differ by a factor of four. Classification performances of ANNs without and with hidden layers were analyzed using tenfold cross-validation. Performance improved with input feature size, with binaural echo classification outperforming that using monaural echoes for the same number of emissions and for the same number of echoes. Linear classification accuracy was comparable to that using nonlinear classification with both achieving fewer than 1% errors with binaural spectrogram features from five sequential emissions. This result was better by a factor of 20 compared to previous classification of these targets using only the time envelopes of the same echoes.

GC-MS analysis of chemical constituents of volatile oil from stems and leaves of Schefflera arboricola Hagata

GC-MS analysis of chemical constituents of volatile oil from stems and leaves of Schefflera arboricola Hagata

Artificial neural network classification of surface reflectors and volume scatterers using sequential echoes acquired with a biomimetic audible sonar.

This paper investigates classifying two target groups, surface reflectors (SR) and volume scatterers (VS), using echo envelope features. SR targets have convex surface patches that exhibit echo persistence over aspect angle, while VS targets are composed of random range-distributed and oriented reflectors producing echoes that become uncorrelated with small changes in aspect angle. The SR target group contains single-post (P1) and multiple-post (PM) types and the VS group contains Ficus benjamina (F) and Schefflera arboricola (S) foliage types with leaf areas that differ by a factor of 4. A biomimetic sonar emitting audible clicks acquired sequences of up to three binaural echoes from target views separated by 18°. Two artificial neural networks performing linear and nonlinear classification first differentiated SR/VS target groups and then P1/PM and F/S types. Classification performance improved with echo number, from a single monaural echo to three pairs of binaural echoes, demonstrating the benefit of sequential echoes. Linear and nonlinear classification of SR/VS targets achieved a minimum generalization error probability PEG = 0.003. Nonlinear P1/PM classification achieved PEG = 0.009 that was four times smaller than linear classification. Nonlinear F/S classification achieved PEG = 0.220, indicating that envelope features by themselves are inadequate to accurately differentiate foliage targets.
