The effect of social skills-based blended education on social adjustment, self-esteem and social skills among new nursing students: An experimental study

IntroductionSocial adjustment, self-esteem and social skills may influence students' professionalization and academic success. The aim of this study was to determine the effect of a social skills-based blended education on the social adjustment, self-esteem and social skills of new nursing students. MethodsFirst-year undergraduate nursing students in Tehran, Iran, participated in this experimental study in 2023. Participants were selected from two classrooms, one as a control group (26 people) and the other as an intervention group (26 people). The study instruments included the California Personality Test, the Coopersmith Self-Esteem Inventory and the Teenage Inventory of Social Skills. The social skills-based blended education was delivered in 10 sessions of blended education (traditional and virtual education). Data were collected at three stages including baseline, immediately and one month after the intervention. A significance level of 0.05 was used. ResultsAccording to the results, the average score of social adjustment and social skills of the students in the intervention group increased significantly from baseline to one month after the intervention (P < 0.001). In the control group, this variable did not increase significantly. The results of the two-way repeated measures ANOVA (comparing the effect of time and group) showed that social skills-based blended education can improve the overall average score of students' social adjustment and social skills (P < 0.001 and P = 0.01 respectively), but it had no significant effect on their self-esteem. ConclusionThe findings can be used by managers and educational planners to design and implement social skills-based blended education in order to improve the social adjustment and social skills of new nursing students.

Statistical inference on nonparametric regression model with approximation of Fourier series function: Estimation and hypothesis testing

Nonparametric regression is an approximation method in regression analysis that is not constrained by the assumption of knowing the regression curve. One of the functions to approximate the curve is a Fourier series function. The nonparametric regression model with approximation of a Fourier series function has been widely discussed by several researchers. However, discussions on statistical inference, particularly in partial hypothesis testing, has not been carried out previously. Therefore, the purpose of this research is to discuss the statistical inference on nonparametric regression model with approximation of a Fourier series function. The discussion includes parameter and model estimations, simultaneous and partial hypotheses testing. In the application, we use life expectancy data from East Java Province during 2022. Based on data analysis, we obtain a model estimation with an R-square value of 96.24 %. At a 5 % significance level, the parameters simultaneously have a significant influence on the model. Partially, four parameters are not significant. However, overall, the predictor variables significantly influence the life expectancy data.•The Fourier series function used is a Fourier series function introduced by Bilodeau (1992).•The model estimation is obtained by selecting the optimal number of oscillation parameters.•The statistical test is obtained using the LRT method.

Addressing maximization bias in reinforcement learning with two-sample testing

Value-based reinforcement-learning algorithms have shown strong results in games, robotics, and other real-world applications. Overestimation bias is a known threat to those algorithms and can sometimes lead to dramatic performance decreases or even complete algorithmic failure. We frame the bias problem statistically and consider it an instance of estimating the maximum expected value (MEV) of a set of random variables. We propose the T-Estimator (TE) based on two-sample testing for the mean, that flexibly interpolates between over- and underestimation by adjusting the significance level of the underlying hypothesis tests. We also introduce a generalization, termed K-Estimator (KE), that obeys the same bias and variance bounds as the TE and relies on a nearly arbitrary kernel function. We introduce modifications of Q-Learning and the Bootstrapped Deep Q-Network (BDQN) using the TE and the KE, and prove convergence in the tabular setting. Furthermore, we propose an adaptive variant of the TE-based BDQN that dynamically adjusts the significance level to minimize the absolute estimation bias. All proposed estimators and algorithms are thoroughly tested and validated on diverse tasks and environments, illustrating the bias control and performance potential of the TE and KE.

An Insight into Practices Associated with the Control of Internal Parasites in the Dairy Goat Herds of Romania: A Questionnaire Survey.

The widespread and uncontrolled use of anthelmintic products has contributed to the emergence of anthelmintic resistance (AR). This phenomenon globally threatens the productivity and welfare of small ruminants. A questionnaire consisting of 34 questions was handed to 234 goat farmers across Romania to gain insight into control practices against internal parasites and the farmers' perception of the parasitic infections present in their herds and the efficacy of anthelmintic treatments. The majority of farmers (88.5%) admitted they had never submitted fecal samples for parasitological laboratory analysis, and 77.4% had treated the animals on their own. In general, the farmers dewormed their goats based on visual body weight estimation. Prophylactic anthelmintic treatment was practiced by more than 85% of the farmers. A traditional control approach based on treating the entire herd at fixed time intervals is widespread among Romanian goat and sheep farmers. The most commonly used anthelmintic drugs in the previous 3 years (2021-2023) were benzimidazoles (85.5%) and macrocyclic lactones (81.6%). Poor anthelmintic efficacy was suspected by 14.5% of farmers, and the minority (18.0%) considered internal parasites as a problem in their herds. Regarding the farmers' perception of the presence of parasites, there was a significant level of uncertainty. This is the first survey carried out in Romanian goat herds, and it provides up-to-date information on practices aimed at controlling internal parasites.

Evaluation of GHG Emissions on Climate of the Braced States in the Niger Delta

This study evaluates greenhouse gas emissions on the climate in the BRACED States of the Niger Delta. The emission of greenhouse gases leads to deforestation, reduced vegetation, and a decline in biodiversity. To achieve the study, an ex post facto research design was used. The study utilised field measurements and historical data to assess these factors. Data were collected and monitored from twelve distinct locations between September 2022 and February 2023. The findings indicate that Akwa Ibom had the lowest concentrations of greenhouse gas and climate variables. The concentrations of greenhouse gases and climate variables were found to be lowest in Akwa Ibom and Rivers States. Similarly, Rivers, Cross Rivers, and Edo States exhibited comparatively lower quantities of carbon dioxide emissions and low rainfall. The study's findings observed a strong correlation between climate (temperature and rainfall) and greenhouse gas emissions in the BRACED states. Statistical analysis at the P&lt;0.05 level of significance indicates that greenhouse gas emissions account for around 32.5% of the observed variations. This analysis offers a method for determining the climate impact of GHG emissions. It is recommended that law on gas flaring activities should be brought to actions.

Transforming discarded walnut green husk into a resource of valuable compounds for colored bioactive textiles with a focus on circular economy concept

This study takes a new look at a circular economy concept for discarded walnut green husks. Their ethanol extract was prepared and characterized using RP-HPLC, then diluted with water and employed for dyeing and/or functionalizing different fabrics. A diluted extract can dye wool (WO), cotton (CO), cellulose acetate (CA), and polyamide (PA) at pH 4.5. Extract:water ratio of 10:40, 65 °C and 75 min and extract:water ratio of 15:35, 45 °C, and 60 min were found suitable for dyeing WO and CA, respectively. Dyed WO and CA exhibited color strength values of 29.0 and 9.2, and excellent antioxidant activity (>97 %) before and after washing, and a significant level of efficacy against S. aureus. CA possessed excellent (5) and very good (4) color fastness to rubbing in a dry and wet state, respectively. WO showed very good (4) and good to very good (3–4) color fastness to rubbing in a dry and wet state, respectively. CO and PA displayed excellent antioxidant activity, with CO also exhibiting significant antibacterial activity against S. aureus even after washing. Moreover, the same dyebath can be reused for up to four dyeing cycles, enabling obtaining bioactive WO and CA fabrics in various brown shades suitable for different applications. Cytotoxicity assay confirmed the non-cytotoxic nature of dyed and washed CA, PA, and CO fabrics. Bioactive WO, CO, CA, and PA fabrics can be considered for the production of wound dressing, performance clothes, and tights for people with sensitive skin. Finally, this paper sheds new light on a novel circular economy concept since collected husks’ solid parts that remained after extraction were converted into activated carbon, which was then used for the preparation of supercapacitor having a specific capacitance of 144–275 F/g at current densities 0.1–2.0 A/g.

Acute lead (Pb2+) exposure increases calcium oxalate crystallization in the inner medullary collecting duct, and is ameliorated by Ca2+/Mg2+-ATPase inhibition, as well as Capa receptor and SPoCk C knockdown in a Drosophila melanogaster model of nephrolithiasis

Calcium oxalate (CaOx) kidney stones accumulate within the renal tubule due to high concentrations of insoluble deposits in the urine. Pb2+-induced Ca2+ mobilization along with Pb2+-induced nephrotoxic effects within the proximal tubule have been well established; however, Pb2+ mediated effects within the collecting duct remains insufficiently studied. Thus in vitro and ex vivo model systems were treated with increasing concentrations of lead (II) acetate (PbAc) ± sodium oxalate (Na2C2O4) for 1 h, both individually and in combination. Pb2+-mediated solution turbidity increased 2 to 5 times greater post-exposure to 75, 100 and 200 μM Pb2+ with the additional co-treatment of 10 mM oxalate in mouse inner medullary collecting duct (mIMCD-3) cells. Additionally, 100 μM and 200 μM Pb2+ alone induced significant levels of intracellular Ca2+ release. To validate Pb2+-mediated effects on the formation of CaOx crystals, alizarin red staining confirmed the presence of CaOx crystallization. Pb2+-induced intracellular Ca2+ was also observed ex vivo in fly Malpighian tubules with significant increases in CaOx crystal formation via Pb2+-induced intracellular Ca2+ release significantly increasing the average crystal number, size, and total area of crystal formation, which was ameliorated by tissue-specific SPoCk C transporter and Capa receptor knockdown. These studies demonstrate Pb2+-induced Ca2+ release likely increases the formation of CaOx crystals, which is modulated by a Gq-linked mechanism with concurrent Ca2+ extracellular mobilization.

The Immediate Effects of a Standardized Kettlebell Swing Protocol on Lumbar Paraspinal Muscle Function: A Randomized Controlled Trial.

Hanney, WJ, Perez, A, Collado, G, Palmer, AC, Wilson, AT, Richardson, RM, and Kolber, MJ. J Strength Cond Res XX(X): 000-000, 2024-Kettlebell swings (KBSs) are commonly used to target the lumbar erector spinae and lower body musculature. This exercise exhibits distinct loading properties that requires cyclical contraction of the trunk extensors and posterior chain, potentially explaining its novel influence on muscle contractility. Tensiomyography (TMG) is a reliable, noninvasive, passive technique that may be used to examine muscular fatigue produced by exercises such as KBSs. The purpose of this randomized control trial was to determine the extent of muscle fatigue in the lumbar erector spinae musculature following the performance of a previously published high-intensity interval KBS protocol. Forty-one adults between the ages of 18 and 45 years were recruited. Inclusion criteria included subjects with no recent history of low back pain and clearance by the physical activity readiness questionnaire. Subjects were randomly allocated to either a KBS group (n = 21) or a control group (CON; n = 20) who only performed the unloaded warm-up. Subjects were assessed at baseline, postintervention, and 24-hours postintervention for bilateral erector spinae fatigue, measured by 5 TMG parameters (Dm, Tc, Tr, Td, and Ts). The results were evaluated through a 2 × 3 (group × time) repeated-measures analysis of variance. The level of significance was set at p ≤ 0.05. There was no significant difference in lumbar erector spinae fatigue, measured by the 5 TMG parameters (p ≥ 0.079), following the interval KBS protocol in comparison with the CON group at 3 assessment periods. A high-intensity interval KBS protocol failed to produce significant differences in erector spinae fatigue compared with the control group that did not perform a KBS. These findings warrant further investigation into muscle fatigue produced with higher intensity protocols and possibly suggest, depending on the programming goals, the need for an alternate KBS training parameters.

SIGNIFIKANSI PENGUASAAN MUFRADAT TERHADAP KEMAMPUAN BERBICARA BAHASA ARAB DI PONDOK PESANTREN AL-KAUTSAR TANJUNGPINANG

Arabic is one of the international languages that students must master to face the increasingly advanced era of globalization. This research aims to provide an overview of the mastery of vocabulary (mufradat) and Arabic speaking patterns by the students. Whether the two have a significant relationship or influence or not. The results of the research show that the students of Al-Kautsar Islamic boarding school have good mastery of mufradat with a percentage of 74.95 and the ability to speak Arabic also shows good results with a percentage of 68.08%. Then, it is known that rxy: 0.939 &gt; r-table at the 5% and 1% significance levels (0.939&gt;0.203&gt;0.264). Thus, between the mastery of mufradat and the ability to speak Arabic of the students of the al-Kautsar Islamic Boarding School, Tanjungpinang, there is a very strong significant influence.

Post-activation performance enhancement (PAPE) protocols do not further increase jumping performance beyond warm-up effects: findings from three acute randomized crossover trials.

Introduction: Post-activation performance enhancement (PAPE) cannot be clearly distinguished from and may be explained in large by warm-up effects. To disentangle PAPE from a systemic warm-up effect, we conducted three randomized crossover trials (RCT). Methods: Each RCT consisted of a familiarization/one-repetition-maximum (1RM) assessment session followed by two interventional sessions (random order). In Study I, 18 participants (age: 26 ± 4years; height: 1.84 ± 0.06m; mass: 83.7 ± 8.7kg; Squat-1RM: 146 ± 19kg) performed either a 3-s isometric squat at 130%1RM or a 6-s isometric squat at 65%1RM. In Study II, 28 participants (11 female; age: 23 ± 3 years; height: 1.77 ± 0.08m; mass: 76.5 ± 10.4kg; Squat-1RM: 109 ± 38kg) completed either Squat (3 × 3 repetitions, 85%1RM) or local electromyostimulation of the quadriceps muscle (85% of individual pain threshold). In Study III, 20 participants (6 female, age: 25.0 ± 3.5 years, mass: 78.5 ± 15.8kg, height: 1.75 ± 0.08m; SQ-1RM: 114 ± 33kg, chest-press-1RM: 74 ± 29kg) performed either squats or chest press (4 repetitions, 80%1RM). Counter-Movement-Jump height (CMJ) was assessed after a general (PRE) and/or muscle-specific warm-up (POST_WU) and for up to 11min after the PAPE protocols. To identify possible differences in CMJ between the experimental conditions, mixed-design ANOVA models were used for each study individually, with condition and time modelled as fixed effects, while participants were included as a random effect blocking factor. The level of statistical significance was set at α = 5%. Results: In studies I and II, significant effects for time (p < 0.05, ωp 2 = 0.06 and p < 0.001, ωp 2 = 0.43) were found with the highest CMJ compared to all other time points at PRE (≤8.2 ± 4.6%, standardized mean difference: ≤0.39), regardless of condition. In study III, no significant effects were observed. Discussion: Thus, PAPE protocols do not further improve jumping performance compared to a general and muscle-specific traditional warm-up. Prior to tasks requiring explosive strength, general and sport-specific warm-up strategies should be used.

Vascular smooth muscle cell-derived exosomes promote osteoblast-to-osteocyte transition via β-catenin signaling

Blood vessel growth and osteogenesis in the skeletal system are coupled; however, fundamental aspects of vascular function in osteoblast-to-osteocyte transition remain unclear. Our study demonstrates that vascular smooth muscle cells (VSMCs), but not endothelial cells, are sufficient to drive bone marrow mesenchymal stromal cell-derived osteoblast-to-osteocyte transition via β-catenin signaling and exosome-mediated communication. We found that VSMC-derived exosomes are loaded with transcripts encoding proteins associated with the osteocyte phenotype and members of the WNT/β-catenin signaling pathway. In contrast, endothelial cell-derived exosomes facilitated mature osteoblast differentiation by reprogramming the TGFB1 gene family and osteogenic transcription factors osterix (SP7) and RUNX2. Notably, VSMCs express significant levels of tetraspanins (CD9, CD63, and CD81) and drive the intracellular trafficking of exosomes with a lower membrane zeta potential than those from other cells. Additionally, the high ATP content within these exosomes supports mineralization mechanisms, as ATP is a substrate for alkaline phosphatase. Osteocyte function was further validated by RNA sequencing, revealing activity in genes related to intermittent mineralization and sonic hedgehog signaling, alongside a significant increase in TNFSF11 levels. Our findings unveil a novel role of VSMCs in promoting osteoblast-to-osteocyte transition, thus offering new insights into bone biology and homeostasis, as well as in bone-related diseases. Clinically, these insights could pave the way for innovative therapeutic strategies targeting VSMC-derived exosome pathways to treat bone-related disorders such as osteoporosis. By manipulating these signaling pathways, it may be possible to enhance bone regeneration and improve skeletal health in patients with compromised bone structure and function.

A retrospective study of tracheal collapse in small-breed dogs: 110 cases (2022-2024).

The grade of tracheal collapse (TC) is assessed by the diameter of the narrowed lumen. However, studies on the relationship between TC grade and clinical symptom severity are lacking. To investigate the clinical characteristics of small-breed dogs diagnosed with TC and determine if fluoroscopic grading correlates with cough severity. We retrospectively reviewed medical records from 2022 to 2024. TC diagnosis was confirmed using fluoroscopic examination. Multiple linear regression was employed to investigate factors influencing cough severity, with a significance level set at p < 0.05. A total of 132 dogs with TC were identified, of which 22 were excluded. The final cohort consisted of 110 dogs, aged between 2-19 years, with no significant sex differences. The majority (97.2%) of dogs had a BCS of ≥4. Among the top four breeds (Maltese, Pomeranian, Poodle, and Chihuahua), the most severe collapse was observed in the carinal region. The grade of collapse on fluoroscopy was mostly related to high BCS (p < 0.007) and low body weight (p < 0.001). However, interestingly, fluoroscopic findings of collapse location and grade did not correlate with cough severity (p = 0.350). Notably, clinical symptoms improved in 86.6% of cases following interventions such as weight reduction, environmental changes, and pharmacotherapy. In small-breed dogs, the severity of cough was not associated with the region or grade of TC diagnosed by fluoroscopy.

Undernutrition, socio-demographic characteristics and eating habits of the elderly

Ageing is often accompanied by a decrease of food consumption, possibly leading to undernutrition. A single nutritional study was conducted in 2011 in the general population, showing that 5.5% of people aged >65 years were undernourished. The aim of our study was to assess the prevalence of undernutrition in the elderly and its relationship with sociodemographic characteristics and dietary habits. A cross-sectional study was conducted on a representative sample of subjects aged ≥60 years in urban and rural areas of the country's eight administrative regions. A questionnaire including socio-demographic data, food consumption frequencies and anthropometric measurements was used. Student's t-test and Man Whitney test were used with a significance level of 5%. A multivariate analysis was performed between undernutrition and the other factors collected. 1698 older adults were included (male: 63.5%, sex ratio M/F=1.7), with a mean age of 71.6±9.4 years and a BMI of 22.6±4.4kg/m2. The prevalence of undernutrition was 14.4%. Undernutrition was significantly associated with age 80-89 years and ≥90 years, (p=0.0001 and p=0.0001 respectively), male sex (p=0.006), rural areas (p=0.002), being in activity (p=0.009) and fish consumption (p=0.039). Breakfast was consumed every day in 87.2% of cases, lunch in 74.3% and dinner in 83.2%. Rice and bread were the most consumed food. Early detection of nutritional disorders, nutritional education and promotion of a balanced diet could help improve the health of the elderly.

COVID-19 vaccination and concerns regarding vaccine hesitancy after the termination of the zero-COVID policy in China: A nationwide cross-sectional study

ABSTRACT COVID-19 vaccine hesitancy remains prevalent globally. However, national data on this issue in the general population after the termination of the zero-COVID policy in China are limited. In March 2023, we conducted a nationwide cross-sectional survey among Chinese adults using a self-administered questionnaire. Descriptive statistics and multivariate logistic regressions were employed. Among 4,966 participants, 43.8% reported COVID-19 vaccine hesitancy following the end of the zero-COVID policy in China. Higher rates of vaccine hesitancy were associated with being married (married: OR 1.36, 95%CI 1.17–1.57; other marital status: OR 1.86, 95%CI 1.36–2.55), working in healthcare (OR 1.64, 95%CI 1.38–1.96), having both minors and older adults in the household (OR 1.45, 95%CI 1.20–1.75), having no minors and older adults in the household (OR 1.44, 95%CI 1.17–1.77), having chronic diseases (OR 1.42, 95%CI 1.23–1.64), experiencing adverse events post-vaccination (OR 1.39, 95%CI 1.19–1.61), and uncertainty about previous COVID-19 infection (OR 1.45, 95%CI 1.13–1.86). Conversely, participants who had received the influenza vaccine in the past three years (OR 0.62, 95%CI 0.54–0.72), had previously taken the COVID-19 vaccine (OR 0.44, 95%CI 0.32–0.59), and had higher confidence in vaccines (OR 0.63, 95%CI 0.60–0.67) were less likely to exhibit hesitancy. Our findings indicate a significant level of vaccine hesitancy, underscoring the urgent need for tailored public health strategies to address vaccine hesitancy and improve uptake post-zero-COVID policy in China. A comprehensive understanding of public concerns and related factors is essential for developing effective vaccine communication strategies.

Bilateral hip stability variation in the functional ambulation and kinetic parameters after total hip arthroplasty during leveled walking.

This study determines gender variation, comparing the significance level between men and women related to functional ambulation characteristics after hip arthroplasty. The study focuses on the broader female pelvis and how it affects the rehabilitation regimen following total hip arthroplasty. In this cross-sectional study, 20 cases of right hip arthroplasty were divided into 10 male and 10 female cases, aged 40-65years. The functional ambulation parameters (walking cadence, gait speed, stride length, and gait cycle time) were acquired from the GAITRite device, as well as kinematic values for hip frontal plane displacement and kinetic parameters for ground response force in the medial-lateral direction. An independent t-test showed a significant difference in the kinematic parameter variables for the anterior superior iliac spine, more significant trochanter displacement, and hip abduction angle between the operated and non-operated limbs for each group separately. Regarding the functional ambulation parameters, there was a significant difference in the walking cadence between the operated and non-operated limbs of both male and female groups. Moreover, the output variables of ground reaction force measures revealed significant differences between their operated and non-operated limbs. The linear regression model used was consistent with the current results, demonstrating a weak negative correlation between the abduction angle of the operated hip and gait speed for both male and female groups. Based on the findings, we draw the conclusion that improving a rehabilitated physical therapy program for the abductors of both male and female patients' operated and non-operated limbs is essential for normalizing the ground reaction force value, avoiding focus on the operated hip, and reducing the amount of time that the operated hip's abductors must perform. This involves exposing the surgically repaired limb to the risk of post-operative displacement or dislocation, particularly in female patients.

The Food Additive Benzaldehyde Confers a Broad Antibiotic Tolerance by Modulating Bacterial Metabolism and Inhibiting the Formation of Bacterial Flagella.

The rise of antibiotic tolerance in bacteria harboring genetic elements conferring resistance to antibiotics poses an increasing threat to public health. However, the primary factors responsible for the emergence of antibiotic tolerance and the fundamental molecular mechanisms involved remain poorly comprehended. Here, we demonstrate that the commonly utilized food additive Benzaldehyde (BZH) possesses the capacity to induce a significant level of fluoroquinolone tolerance in vitro among resistant Escherichia coli. Our findings from animal models reveal that the pre-administration of BZH results in an ineffective eradication of bacteria through ciprofloxacin treatment, leading to similar survival rates and bacterial loads as observed in the control group. These results strongly indicate that BZH elicits in vivo tolerance. Mechanistic investigations reveal several key factors: BZH inhibits the formation of bacterial flagella and releases proton motive force (PMF), which aids in expelling antibiotics from within cells to reducing their accumulation inside. In addition, BZH suppresses bacterial respiration and inhibits the production of reactive oxygen species (ROS). Moreover, exogenous pyruvate successfully reverses BZH-induced tolerance and restores the effectiveness of antibiotics, highlighting how crucial the pyruvate cycle is in combating antibiotic tolerance. The present findings elucidate the underlying mechanisms of BZH-induced tolerance and highlight potential hazards associated with the utilization of BZH.

Soil solarisation delivers near zero levels of Fusarium pseudograminearum in cereal crown rot reference sites

The development of commercial varieties that are resistant or tolerant to crown rot caused by Fusarium species is an important goal for cereal breeding programs internationally. Ideally, this research requires experimental sites that are initially free from Fusarium in order to establish treatment plots that compare growth in the presence and absence of these soil- and stubble-borne pathogens. Specifically, the assessment of tolerance requires control plots free of disease to determine the reduction in crop yield in plots where the disease is present. The ability of soil solarisation to reduce the background Fusarium pseudograminearum level occurring at experimental sites in comparison to current stubble management techniques was investigated across three field trials at Wellcamp in Queensland. Stubble from a susceptible durum (Triticum turgidum ssp. durum) cultivar inoculated with F. pseudograminearum was incorporated by cultivation into the trial sites to establish a significant background level of inoculum prior to the application of all subsequent treatment plots. In these trials, solarisation over a period of twelve weeks reduced the presence of F. pseudograminearum to low detection levels when compared to the traditional crown rot management techniques of cultivation or growth of the non-host cover crops mungbean (Vigna radiata) and soybean (Glycine max). No negative effects of solarisation were observed on a subsequent crop of bread wheat (Triticum aestivum), with significantly higher yields observed in the solarised treatments. Solarisation has the potential to deliver near zero level crown rot reference sites for experimental purposes in one short application between cropping seasons.
