Published: May 2023

In this paper, based on the pseudo-totem pole (PTP) circuit, a family of five-level PTP dual boost converters (PDBC) is proposed. Dual boost converter has some unique advantages such as no bridge arm shoot-through risk and no switch body diode reverse recovery problem, so that it has a good application prospect. Compared with conventional three-level PTP converters, PDBCs has higher power density, higher efficiency, and low voltage and current stress. The topological derivation process, working principle, modulation and strategy of the topology are analyzed firstly. Further, the number of power devices, the switches voltage and current stress of the proposed topology is analyzed. Finally, a representative five-level PDBC experimental prototype is designed with AC input 220V/50Hz, DC output 400V/1kW, and peak efficiency of 98.27%. The experimental results show that the five-level PDBC proposed in this paper has higher efficiency and verify the correctness of the topology.

Published: May 2023

Automatic milking systems (AMSs) are among the earliest Precision Livestock Farming developments that have transformed dairy farming worldwide. This review aims to gather, evaluate, and summarize papers that focus on the use of modeling approaches in the context of AMS. We provided a review of 60 articles with a specific focus on cows’ health, production, and behavior/management. The most used modeling approach was Machine Learning (ML, present in 63% of the studies), followed by statistical analysis (14%), fuzzy algorithms (9%), deterministic mod-els (7%), and detection algorithms (7%). Most of the reviewed studies (82%) focused on the detection of cows' health, specifically mastitis, while only 11% were concerned with milk production. Accurate forecasting of dairy cow milk yield and knowledge on the deviation between expected and observed milk yields of individual cows would be beneficial in dairy cow management. Likewise, the study of cows’ behavior and the herd management in AMSs is under-explored (7%). Despite the increasing use of ML techniques in this field there is still a lack of a robust methodology for their application. In particular, we identified a significant gap in the systematic balancing of positive and negative classes for health prediction models.

Published: May 2023

This cross-sectional study was aimed to investigate the relationship between gratitude and life satisfaction, and the mediation role of social support and enjoyment of life among older individuals. The Gratitude Resentment and Appreciation Test, the Enjoyment of Life Scale, the Satisfaction with Life Scale, and the Multidimensional Scale of Perceived Social Support Scale were administered to a sample of 260 older individuals aged between 60 and 80. The main findings revealed a positive association between gratitude and life satisfaction, and social support was a partial mediator in this relationship. Although enjoyment of life was not a direct mediator in the relationship between gratitude and life satisfaction, the final model indicated a significant serial pathway from gratitude to social support and then through enjoyment of life-to-life satisfaction. In conclusion, enhancing gratitude, promoting enjoyment of life, and social support in older individuals might increase their life satisfaction, which in turn might contribute to their successful aging

Published: May 2023

Dementia is a rising public health concern. Feeding and nutritional problems increase as the disease progresses, affecting clinical course and caregiver burden. While some guidelines advise against percutaneous endoscopic gastrostomy (PEG) and tube feeding in advanced dementia, conflicting evidence exists. This study aims evaluating nutritional status and the influence of PEG-feeding on outcome and evolution of nutritional/progonosis markers of patients with severe dementia (PWSD) who underwent gastrostomy for nutritional support. We conducted a 16-year rectrospective study on 100 PEG-fed PWSD with strong familiar support. We evaluated survival PEG-feeding period, safety, and objective nutritional/progonosis data at the gastrostomy day and after 3 months: Body Mass Index (BMI), Mid Upper Arm Circumference, Tricipital Skinfold, Mid-Arm Muscle Circumference, albumin, transferrin, total cholesterol and hemoglobin. Most patients presented low values in these nutritional/progonosis parameters. No major life-threatening PEG complications were reported. The mean survival time after gastrostomy was 27.9 months (median of 17 months). Female sex, BMI recovery at 3 months, and higher baseline hemoglobin levels were associated with a reduced risk of death and increased survival time. The study concluded that, in carefully selected PWSD with strong familiar support, PEG feeding can improve nutritional status and have a positive impact on survival.

Published: May 2023

Neonatal apnoea has been treated with caffeine, affecting the central nervous and the cardiovascular system. Heart rate variability (HRV) reflects the activity of the autonomic nervous system (ANS) and might be used as a measure of ANS maturation in newborns. We aimed to establish the effect of caffeine on HRV in newborns and sought for a potential correlation between HRV and the postmenstrual age. In 25 newborns hospitalized due to apnoea and treated with caffeine (2.5 mg/kg), we assessed breathing frequency, arterial oxygen saturation, body temperature, and the heart rate, while they were sleeping. We assessed HRV by spectral analysis using fast Fourier transformation. The same protocol was reapplied 100 hours after caffeine withdrawal to assess control parameters. Caffeine increased breathing frequency (p=0.023) but did not affect any other parameter assessed including HRV. We established a positive correlation between postmenstrual age and HRV during treatment with caffeine as well as after caffeine had been withdrawn (total power: p=0.044; low-frequency band: p=0.039). Apparently, the maintenance dose of caffeine is too low to affect the heart rate and the HRV. A positive correlation between postmenstrual age and HRV might reflect maturation of ANS, irrespective of caffeine treatment.

Authors: Bohdanowicz Michal , Bradshaw Scott H
Published: May 2023

Perforating dermatoses are dermatologic disorders with transepidermal elimination (TE) of dermal substances. While TE is typically associated with collagen and elastin, it can also occur as a secondary event in other processes, and it is important to keep a broad differential. We present a case of perforating tophaceous gout, which underscores the need for a thoughtful approach to perforating disorders. An updated review of recent literature is also presented.

Published: May 2023

Improper lifting measures of long-span spatial steel structures during construction process may delay the construction period and even cause safety accidents. Few studies on long-span spatial steel structures considered time-varying mechanical characteristic during construction process. In order to achieve safe and efficient installation in a long-span spatial steel structure, this research presents a time-varying mechanical analysis of the synchronous and asynchronous integral lifting and a single and interlaced point’s asynchronous integral lifting analysis method of a long-span spatial steel structure. The results showed that in the case of asynchronous lifting of single point, the displacement influence on other members is related to the distance. The closer the distance from the lifting point, the greater the influence. In asynchronous integral lifting, the lifting point with large lifting force is first installed to the specified position, and the lifting point with small lifting force is installed to the specified position.

Published: May 2023

In this study, Ni50Ti50 powder was coated on the surface of graphite substrate (C) by plasma spraying process using a radio frequency inductively coupled plasma reactor. The coating was carried out by using 12- and 9-kW power under Ar atmosphere. The cross-section of coating layers and the surface were examined with SEM, EDX, XRD analysis and microhardness test. The thickness and quality of the coating increased with input power. Many pores were detected in the cross-sectional surface areas. Higher input power caused a better coating layer in NiTi alloy. The hardness of the coating layer decreases with higher input power.

Published: May 2023

The coronavirus disease 2019 (COVID-19) pandemic has disrupted health care worldwide. As the pandemic has been prolonged, quarantine restrictions have been lightened gradu-ally, which can influence outcomes of pediatric patients with chronic disease such as epi-lepsy by increase of susceptibility of the COVID-19 infection. The aim of this study was to determine impacts of COVID-19 pandemic on seizure control and identify potential risk factors that might worsen seizure attacks during the pandemic in children with epilepsy. We performed a retrospective chart review of 48 pediatric patients with epilepsy during the COVID-19 pandemic from January 2016 to July 2022.
During the COVID-19 pandemic period, 25% of pediatric patients experienced sei-zure worsening, showing an increase in seizure frequency or duration or both.
Factors associated with worsening seizures during pandemic were: diagnosis of epi-lepsy less than one year, comorbid conditions with cerebral palsy or having a tracheosto-my or a PEG, and infection with other viruses (respiratory syncytial virus, influenza virus A, influenza virus B) rather than COVID-19 infection.
Our finding highlights the need to proactively monitor and regularly follow up (es-pecially short period of time) patients after they are diagnosed with epilepsy. It is also important to properly manage those who are susceptible to serious illness and keep sea-sonal viral infections under surveillance to manage exacerbated seizure in children with epilepsy. Furthermore, pediatric physicians should not overlook surveillance of seasonal respiratory viruses since quarantine restrictions are getting eased.

Published: May 2023

The performance of two bio inoculants either in single or in combined applications with organic fertilizer was tested to determine their effect on plant growth and yield under normal and unfavorable field conditions such as low pH value and low content of P. Arbuscular Mycorrhiza Fungi ((AMF; three species of Glomus) and the plant growth-promoting bacterial strain Kosakonia radicincitans DSM16656 were applied to barley in two years field experiment with different soil pH levels and available nutrients. Grain yield, content of P, N, K, Mg, and soil microbial parameters were measured. Grain yield and content of nutrients were significantly increased by the applications of mineral fertilizer, organic fertilizer, AMF, K. radicincitans, and combined application of organic fertilizer with AMF and with K. radicincitans over the control under normal growth conditions. Under low pH and low P conditions, only the combined application of the organic fertilizer with K. radicincitans and organic fertilizer with AMF could increase grain yield and content of nutrients of barley over the control.

Published: May 2023

The objective of this work is to study the physical and mechanical behavior of concrete with the addition of 0.5% and 1.0% of coconut fibers subjected to two chemical treatments in order to reduce their degradation and optimize their use in the elaboration of concrete specimens, which must comply with the standards of the American Society for Testing of Materials (ASTM), the American Concrete Institute (ACI) and the Instituto Ecuatoriano de Normalización (INEN). The coconut fibers were obtained from the raw material by hand and cut to a length of 4 cm. Subsequently, the coconut fibers were subjected to two chemical treatments: The first treatment is the immersion of the coconut fibers in 4% sodium hydroxide (NaOH) solution and the second treatment, the coconut fibers were immersed in gum arabic to consequently coat them with silica fume. A particular dosage was carried out with a proportion of 0.5% and 1.0% volume of coconut fiber for the two chemical treatments, replacing the volume of coarse aggregate. Simple concrete joists were made without fiber and with the post-treatment coconut fibers, which were subjected to flexural tests. The results indicated that the best chemical treatment is sodium hydroxide with a concentration of 4% and 1.0% coconut fiber for strengths of 210 kg/cm² and 240 kg/cm². In general, the joists with coconut fiber treated with sodium hydroxide outperformed the fibers treated with gum arabic and silica fume.

Published: May 2023

The variation of river hydrologic process can not only reflect the impact of natural factors, but also the impact of human activities. The purpose of this study is to reveal the change trend of the hydrologic regime of the Yellow River and its response to ecological protection in the river basin. Based on the daily water and sediment observation data of representative gauging stations in the middle and lower reaches of the Yellow River, it was analyzed the variation trend of the annual and monthly runoff and suspended sediment load (SSL), and monthly mean runoff, suspended sediment transport rate (SSTR), sediment inflow coefficient, and hydrological regime in decadal average of the gauging stations during the period 1960-2019. The results show that the variation of annual runoff and SSL, as well as the monthly mean runoff and SSTR in decadal average, has a significant decreasing trend in the 1960’s-1990’s, which was mainly in response to the gradual implementation of ecological protection measures such as afforestation, grass planting, terrace construction, and check dam construction, etc. in the basin. In 2000’s and 2010’s, the annual runoff increased, while the SSL increased slightly. This was a response to the implementation of new river management measures such as ensuring the ecological water demand of the lower reaches and scouring the riverbed by manually regulated clear water discharged from the Xiaolangdi Reservoir. In the same time, the monthly mean runoff and SSTR for the flood season (Jun.-Oct.) decreased remarkably, while the process curve of the monthly mean discharge and sediment concentration, changed from a clockwise loop to a counterclockwise loop in the river reach below the Xiaolangdi dam. This was a comprehensive response to the environmental protection measures in the Yellow River basin, in which the construction and operation of the Xiaolangdi Reservoir played a key role. This study can provide reference for river basin management.

This study evaluated the effectiveness of an electronic system for managing drug-sensitive pulmonary tuberculosis patients in the Kyrgyz Republic. This was a cohort study using programmatic data. The study included patients registered on the paper-based system in 2019 and the electronic system between June 2021 and May 2022. Data was taken from 302 individuals from the electronic system for completeness and concordance in comparison with the paper-based system. The study showed that for most variables the completeness and concordance was 85.3%-93.0% and was lowest for non-mandatory fields such as medication side effects (26.8% vs 13.6%). No significant difference was observed in time taken from symptom onset to diagnosis and treatment initiation between the two systems. However, the electronic system had a significantly higher percentage of patients who initiated treatment on the same day of diagnosis (80.3% vs. 57.1%). The proportion with successful outcomes was similar in both groups, but the electronic system had a significantly lower proportion of patients with outcomes that were not evaluated or recorded (4.8% vs. 14.3%, p < 0.001). The study highlights the potential advantages of implementing an electronic TB register system for improving records. We advocate for similar studies in other regions in Kyrgyz Republic.
Neutrophil Depletion Attenuates Acute Renal Injury after Exhaustive Exercise in Mice
Authors: Mizokami Tsubasa , Shimada Michikio , Suzuki Katsuhiko
Published: May 2023

Prolonged exercise induces acute renal injury; however, the precise mechanism remains unclear. We investigated the effects of neutrophil depletion in male C57BL/6J mice. Male C57BL/6J mice were divided into four groups: sedentary with control antibody, sedentary with antineutrophil antibody, exhaustive exercise with control antibody, and exhaustive exercise with antineutrophil antibody. Antineutrophil (1A8) or control antibody was administered intraperitoneally to the mice prior to their running on a treadmill. Renal histology was assessed 24 h after exhaustive exercise, and the concentration of kidney injury molecule (KIM)-1 was measured using enzyme-linked immunosorbent assay. The expression levels of inflammatory cytokines were measured using quantitative reverse transcriptase-polymerase chain reaction. Furthermore, nicotinamide adenine dinucleotide phosphate oxidase activity and hydrogen peroxide concentration in the kidneys were measured. The pathologic changes were manifested as congested and swollen glomeruli, tubular dilatation, and nuclear infiltration after exhaustive exercise. These changes were suppressed by the administration of the 1A8 antibodies. KIM-1 concentration increased after exhaustive exercise but were reduced by the 1A8 antibodies. Treatment with the 1A8 antibody also decreased exhaustive exercise-induced inflammation and reactive oxygen species levels in the kidney. These results suggest that neutrophils contribute to exercise-induced acute renal injury by regulating inflammation and reactive oxygen species levels.

Published: May 2023

Promoting diet and physical activity is important for women with recent gestational diabetes mellitus (GDM) and their partners to reduce the risk of future type 2 diabetes (T2D). The study aimed to understand how motivation for changing diet and physical activity behaviors among women with recent GDM and their partners was experienced after participation in the Danish Face-it intervention. Fourteen couple interviews were conducted. Data analysis followed reflexive thematic analysis. Guided by self-determination theory and interdependence theory, we identified four themes affecting couples’ motivation for health behavior change: 1) The need for relatedness after delivery, 2) Promoting competence and autonomy for health behavior change, 3) Individual and mutual preferences for health behaviors, and 4) The health threat of future T2D as a cue to action. We found that the couples in general perceived the Face-it intervention as useful and motivating. Using couple interviews increased our understanding of how the women and partners influenced each other’s perspectives after a GDM-affected pregnancy and thus how targeting couples as opposed to women alone may motivate health behavior change.

Practical factors that influence physical activity in women living with metastatic breast cancer: a qualitative interview study
Authors: Liu Mark , Kilbreath Sharon , Yee Jasmine , Beith Jane , McNab Justin , Dylke Elizabeth
Published: May 2023

Background: Women living with metastatic breast cancer can benefit from physical activity. To enable effective physical activity advice and services, it is important to understand the practical factors that may facilitate or prevent engagement. For women living with metastatic breast cancer, we explored: i) practical and behavioural factors that influenced physical activity, and ii) the role of healthcare services in influencing engagement in being physically active.
Methods: Recruitment took place at a metropolitan cancer centre. Women living with metastatic breast cancer were asked to participate in semi-structured interviews about physical activity, covering health-specific factors, goals, barriers, enablers, and interests. Interviews were recorded, transcribed and thematically analysed.
Results: Twenty-three women completed the interview, with a median age of 60 years (IQR: 20) and median time since metastatic diagnosis of 3.3 years (IQR: 3.0). Physical activity levels ranged from regular participation in structured exercise to simple incidental activity. Seven themes organised into three categories were identified. The category ‘personal context’ incorporated themes on: 1) both cancer and non-cancer related health factors; 2) time, work and family factors; and 3) exercise history and preferences. The category ‘strategies for physical activity’ incorporated themes on: 4) self-efficacy, and 5) routine and incidental activity. The category ‘role of health and physical activity services’ incorporated themes on: 6) tailored education and services, and 7) specific metastatic cancer services and considerations.
Conclusions: Participants expressed diverse experiences with physical activity, with common notions on how physical activity is beneficial but difficult in which to adhere. Whilst some barriers to engagement in physical activity were unique to having cancer, many were not specific to metastatic breast cancer. A patient-centred approach tailored to this group’s health and behavioural context may be effective for women who are currently inactive to engage in physical activity.
A new algorithm for investigating strongly correlated systems using Hubbard model
Authors: Rabi-‌‌beigi Poorya , Moradian Rostam
Published: May 2023

In this work for an interacting electrons system that obeys the Hubbard model, a new quantum Monte Carlo algorithm introduces for calculation of average Green function. This algorithm is applied to investigate the effects of electrons onsite Coulomb repulsion on the band structure of a square lattice in both single-site approximations such as dynamical mean field theory (DMFT) and multi-site approximations such as effective medium supercell approximation (EMSCA). The advantages of our algorithm in comparison to the Hirsch-Fye algorithm and also the Blankenbecler, Scalapino, and Sugar (BSS) algorithm are the elimination of instabilities resulting from the Metropolis algorithm in the accepting and rejecting configurations, stability at low temperatures, the elimination of systematic errors resulting from the update of the Green's function in the quantum Monte Carlo process, and considering different probabilities for each possible configuration. Finally, by using our algorithm, it is possible to calculate the interacting three-dimensional system's band structure and the density of states that obey the Hubbard model. We have applied our algorithm to an interactive two-dimensional square lattice. As a result, phase transition boundaries can be easily recognized through calculated bands for different repulsions. Our results show that critical Coulomb repulsion values for Mott transition are uc=9.05t and uc=2.4t for DMFT and BEMSCA respectively. This means that DMFT significantly overestimates band splitting due to electrons' Coulomb repulsion. We found by starting at low repulsions and then increasing electrons' Coulomb repulsion, a partially flatted valance band around the center of the first Brillouin zone appears, but disappears at high repulsions.

To enhance the level of refined load decomposition of the power system and make full use of seasonal change information to improve the prediction performance further, this paper proposes a seasonal short-term load combination prediction model of the power system based on modal decomposition and feature fusion multi-algorithm hybrid neural network model, i.e., the characteristics of load components are analysed for different seasons, and the corresponding models are established respectively. Firstly, The ICEEMDAN (Improved complete ensemble EMD) method decomposes the four-season load, and a new sequence is obtained based on the RCMFE (refined composite multiscale fuzzy entropy) reconstruction of each decomposition component. Secondly, the correlation between different decomposition components and different features is measured using the mRMR (Max-Relevance and Min-Redundancy) method to filter out the subset of features with high correlation and low redundancy. Finally, the BiLSTM (Bi-directional Long Short-Term Memory) model based on the Bayesian optimisation algorithm is used to predict different components of different seasonal loads separately, and the predicted values are accumulated to obtain the final results. According to the experimental findings, the proposed method can successfully balance the issues of prediction accuracy and prediction time while having a higher level of prediction accuracy than the current prediction methods. It is confirmed that the proposed method can effectively address the load power variation brought on by seasonal differences in different regions.

Purpose
Non-invasive biomarkers are useful in determining treatment strategies for elderly patients with early gastric cancer (EGC). The systemic inflammatory or nutrition-based index including neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) lymphocyte to monocyte ratio (LMR), and prognostic nutritional index (PNI) are useful for the assessment of prognosis for various cancers. The aim of this study was to investigate the significance of these index for predicting the long-term survival of EGC patients who were 80 years old or older.
Methods
This study included 80 elderly EGC patients with pStage IA after gastrectomy. The optimal cutoff value for the PNI, NLR, PLR and LMR were set by using a receiver operating curve analysis. The long-term outcomes after gastrectomy were analyzed by univariate and multivariate Cox regression analyses.
Results
The cutoff value for the PNI, NLR, PLR and LMR was set at 46.5, 2.8, 210 and 4.6, respectively. By univariate analyses, the low PNI, high NLR, high PLR and low LMR were significantly associated with worse OS. By multivariate analysis, only low PNI was confirmed as an independent prognostic factor for OS after gastrectomy (HR 0.17; 95% CI 0.03–0.91; P = 0.04). The 5-year overall survival rate of patients with the low PNI (≤ 46.5) were only 52.4%.
Conclusion
The low PNI (≤ 46.5) is a significant worse prognostic factor after gastrectomy for the elderly EGC patients with pStage IA. Gastrectomy for the elderly EGC patients with the low PNI might need to be carefully considered for its indications.

Background
Liver tumors are commonly encountered in Oncology. The study aimed to assess the impact of MRI-guided SBRT (MRgSBRT) on disease-related outcomes and the toxicity profile.
Methodology
Patients who received MRgSBRT from 2019 to 2021 for primary and metastatic liver tumors were included in this analysis. The protocol for treatment simulation included Gadoxetate disodium injection followed by a single-dimensional post-exhale MRI(0.35 T MRI linear accelerator) and CT simulation. The patient demographics and treatment-related outcomes were assessed. The time-to-event curves were analyzed for freedom from local progression (FFLP) and overall survival (OS).
Results
A total of 35 patients were eligible for analysis with a median age of 70 years (range 25–95). The median follow-up was 19.4 months (range 1–37 months). The one-year OS was 77.7%, with an estimated 3 years of 47.9%. Patients with locally controlled disease had better median overall survival of 27.8 months [95%CI (23.8–31.6)] compared to 13.5 months [95%CI (5.6–21.3), p = 0.007] in patients with local disease progression. The one-year FFLP was 95.6%, and three year estimated FFLP was 87.1%. Patients who received a radiation dose of BED ≥ 100Gy had FFLP of 30.9 months [95%CI (28.7–33.1)] compared to 13.3 months [95%CI (5.3–21.3), p value = 0.004] in patients who received < 100Gy BED.
Conclusion
MRI-guided SBRT provides optimal local control, associated with improved overall survival in a heavily morbid, pretreated older cohort of patients with reasonable safety profiles.

Soil carbon (C) responses to environmental change represent a major source of uncertainty in the global carbon cycle. Feedbacks between soil C stocks and climate drivers could impact atmospheric CO2 levels, further altering the climate. Here, we analyzed and intercompared the soil C change in multiple Earth system models (ESMs) of the Coupled Model Intercomparison Project phases 5 and 6 (CMIP5 and CMIP6). Earth system models predicted global soil C gains under the high emission scenario, with soils taking up 43.9 Pg [95%CI: 9.2–78.5 Pg] C on average during the 21st century. The variation in global soil C change declined significantly from CMIP5 to CMIP6 models. Dominant processes underlying soil C change at global or biome scales differed among models and in many cases between the two phases for the same models. Model structure accounted for more than 60% variation of the global soil C change predicted by CMIP5 ESMs, but only 36% for CMIP6 models. Although current Earth system model predictions were converging on increased soil C storage during the 21st century, this consensus obscured substantial model disagreement on the mechanisms and spatial variation of soil C response to climate change.

Phosphorus (P) is the second most important nutritional element for plant growth and improves the balance of forest soil ecology. In this study, nutrient elements were comparatively evaluated as phosphorus fractions in soil using sequential extraction using a UV-VIS spectrophotometer from typically degraded Hustai and naturally regenerated Udleg, Batsumber. The objective of this study was to assess the effects of different land-use and slope aspects on soil inorganic phosphorus (Pi) and organic phosphorus (Po) fractions with different availabilities. In this study, labile P decreased with decreasing slope in the Udleg plots, whereas nonlabile P and calcium-bound phosphorus (Ca-P) increased with decreasing slope in the Udleg plots. Furthermore, aluminum-bound phosphorus (Al-P) and Ca-P showed no changes by the slopes in the Hustai plots. The contents of nonlabile Po and moderately labile Po in Hustai and Udleg were higher than those of labile Po. The content of nonlabile Po in Udleg soil was significantly higher (t-test, p < 0.001) than in Hustai, which indicates that humic acid-bound P (humic-P) was derived from plants. A high Ca-P content was recorded at the lower forest edge of Hustai.Low-labile Po was derived from organic residues in Hustai and plant residues in Udleg, which were easily mineralized by soil microbes. The incorporation of organic and plant residues in Hustai and Udleg, respectively, increased soil pH, contributing to P availability for plant uptake. Further studies are needed to determine the nutritional elements in plants, evaluate their relationship with the soil, and evaluate their ecological significance.
