Optimization of Vacuum Freeze-Drying Process and Quality Evaluation of Stropharia rugosoannulata

Stropharia rugosoannulata is a valuable medicinal and food fungus with high nutritive value. Freeze-drying addresses the storage and transportation challenges of fresh Stropharia rugosoannulata, expanding its market while preserving its flavor and quality more effectively than other drying methods. This study optimizes the vacuum freeze-drying process for Stropharia rugosoannulata using an orthogonal experiment method. The process parameters were optimized to determine their effects on the quality of the vacuum freeze-dried product, including pre-freezing temperature, pre-freezing time, and freeze-drying time. The optimal conditions were identified as a pre-freezing time of 60 h, a pre-freezing temperature of −80 °C, and a freeze-drying time of 72 h. The optimal product exhibited a bright color close to its natural state, with minimal browning and its natural white color maintained post-drying. During the drying process, the internal structure of the raw materials remained intact. After drying, the finished product retained its natural form, making it suitable for sale on the market. The soluble protein content of the vacuum freeze-dried Stropharia rugosoannulata reached 68 mg/g. Optimizing the freeze-drying process can better preserve the tissue structure and bioactive substances of Stropharia rugosoannulata, providing a reference for high-quality food processing and showing potential for sustainable development.

Evaluation of clarification process of Indonesia’s sweet sorghum juice by ultrafiltration membrane and the physicochemical and sensorial properties of the sugar product

The juice derived from Sorghum bicolor L. exhibits a notable sugar content, rendering it a promising candidate for use as a sweetening agent. The presence of impurities in sorghum juice encompasses several substances such as non-sugar molecules, non-fermentable reducing agents, starch, and minerals like salt, magnesium, and calcium. The objective of this study was to investigate the impact of ultrafiltration (UF) membranes on the physicochemical properties of sorghum juice and sugar granules, as well as to identify customer preferences for these products. The study consisted of three primary phases. The first phase involved investigating the impact of 0–3 cycles of UF treatment on the physicochemical properties of the sorghum juice. The second stage involved comparing the characteristics of sugar granules obtained through UF and non-ultrafiltration (non-UF) methods. The third one focused on examining the preference of sorghum sugar granules in their natural state and as a sweetener for steeped black tea. A 5% significance level was employed in this work to conduct multivariate methodology of variance and the Friedman nonparametric test. The findings of the study indicate that the use of UF treatment has a simultaneous impact on the turbidity and color of sorghum juice. Non-UF sorghum sugar granules exhibit a superior aroma in comparison to UF granules while maintaining identical color, taste, and texture. Consumers exhibited a preference for steeped black tea sweetened with palm sugar, followed by rock sugar, granulated sugar, UF sorghum sugar granules, and non-UF.

Why are the Category of "Unnecessary" Borrowings or Parallel Lexical Units Still Present in Standard Albanian Language?

Language, as a complete system of units and rules and at the same time a system not isolated, but open to changes, is the property of the society that uses it. Linguistic development and social development are accompanied by a mutual relationship between them, it would even be right to express the well-known definition that: there is no development that takes place in a society that does not leave its traces in the language system, especially in the system its lexicon. The developments that Albanian society has undergone in recent decades have made it possible for a relatively large number of borrowings to enter the Albanian language, mainly anglicisms. This phenomenon has caused a good part of Albanian linguists to be involved in the so-called cleaning process of relatively new borrowings or borrowings of the last decades in the Albanian language. Although discussions about the category of borrowed in the Albanian language constitute a very early linguistic reality, it should be noted that in the publications and scientific conferences of recent years it still continues to be treated as a matter of primary importance and as a growing phenomenon of continuous. Naturally, the perspectives of Albanian linguists on this field of study are different: some see the issue of borrowings as a very big damage done to the Albanian language, others see it as a natural state of language development, but not dangerous. for her. Despite the sometimes similar and approximate attitudes, but sometimes even contradictory, the aspect that unites most of the linguists who have dealt with this issue is related to the context in which the borrowed word is used, while the Albanian language has her answer. The questions we would raise in this context are: Should we call the phenomenon of the presence of "unnecessary borrowings" common in the Albanian language? The deep penetration into Albanian of these "parallel lexical units" or "synonyms" with the Albanian word should be seen and accepted as a natural development of the language and as a result of linguistic interaction in the conditions of global development, or should it be considered as a phenomenon that should be observed, even monitored, to some extent controlling its trends and developments?The aim of the paper is to create a description and reflection of the real situation of borrowings in Albanian, the place they have occupied in relation to the Albanian word and the approach of Albanian linguists and linguistics to this phenomenon. In another perspective, the paper aims to emphasize the irreplaceable role of the state and propose the creation of the missing law for the Albanian language in the Albanian legislation, with the aim of preserving the language from unnecessary linguistic elements that overlap the linguistic elements of its substratum autochthonous.

Photo-fenton catalysis degradation of 4-dodecylmorpholine by heterogeneous microprocessor Cu2O/SnO2

The increasing demand for potash has led to the increased use of 4-dodecyl morpholine (DMP), an important froth flotation agent for the extraction for potash extraction by “reverse flotation-cold crystallization”. As it is not easy to be stable and decompose in its natural state, it has seriously endangered the environment of salt lakes and the development of salt lake resources. The development of a safe and harmless catalytic system to accomplish the degradation and removal of DMP is urgent. Herein, A Cu2O/SnO2/PDA (CSP) nanoparticle with a synergistic effect of photocatalysis and Fenton-like catalysis was developed, and the CSP had a good photothermal conversion efficiency. Under 808 nm NIR irradiation, not only the catalyst activity was enhanced, but also the complexation rate of electron-hole pairs was reduced, which effectively increased the degradation efficiency of DMP (an increase of about 31.56 %). In addition, by analyzing the degradation products of DMP, the possible pathways of the DMP degradation process were proposed and, at the same time, the degradation catalytic system we used was proved to be safe and harmless. A new pathway is provided for the degradation and removal of DMP in the salt lake environment.

Numerical simulation study on the force of overwintering foundation support structure of unsaturated seasonal permafrost under indoor experiments.

When analysing the effect of negative temperature on overwintering pit constructions of unsaturated soil, using the mechanical parameter of saturated soil at room temperature leads to an inaccuracy in the research findings. The strength parameters are obtained through indoor experiments. The foundation pit model is created using FLAC3D numerical simulation software based on the indoor experimental data. The influence of different parameters on the stress and deformation of the overwintering deep foundation pit supporting structure is analysed. The numerical simulation results obtained are compared with the actual monitoring data. According to research, the matric suction of the silty clay in its natural state in the Changchun area is 70 kPa. As the temperature decreases, the total cohesion of the unsaturated soil increases, and the internal friction angle tends to decrease. The numerical simulation results are consistent with the actual monitoring data changes. With the excavation, the horizontal displacement of the supporting structure increases first and then decreases, reaching the maximum displacement at two-thirds of the foundation pit. Compared with room temperature, the deformation of the supporting structure is larger under a negative temperature condition. The deformation of the supporting structure simulated by the actual temperature mechanical parameters is larger than that under the condition of normal temperature mechanical parameters. The frost-heaving force increases with the overall excavation, and a surge occurs at the bottom of the pit. The frost-heaving force changes most significantly under the condition of freezing at -20°C for 30 days.

Role of aromatic and non-protonated aromatic carbon in the stability of soil organic matter

Research on soil organic matter (SOM) in its natural state is vital for comprehending the mechanisms governing soil stability and carbon cycling, crucial in addressing global climate change. We utilized solid-state 13C nuclear magnetic resonance (NMR) spectroscopy on HF treated samples, along with a 260-day laboratory mineralization experiment and thermal analysis-programmed pyrolysis (PP) to evaluate SOM biodegradability and thermal stability. To cover the potential range of organic carbon variability, we selected samples from three land uses and soil types, featuring total organic carbon levels from 1% to 39%. Our analysis confirmed the substantial contribution of non-protonated aromatic-carbon not bonded to oxygen to SOM’s biological and thermal stability, constituting approximately 14–21% of soil organic carbon. These components exhibited a strong correlation with SOM stability matrices, such as thermal stability and oxygen index determined by PP. Samples with a higher prevalence of these components also displayed the lowest cumulative carbon mineralization. These findings enhance our understanding of the stable SOM pool, aiding in the identification of sustainable soil management practices to mitigate climate change impacts on soil health and carbon dynamics.

Practice by Unpractice: Taizhou Moral Philosophy Reconsidered

As followers of Wang Yangming, the Taizhou school places significant emphasis on the body, which has led to challenges concerning the potential dissipation of natural desires. Critics argue that Taizhou philosophy, while acknowledging human’s natural state, fails to adequately address the existence of evil and tends to overlook the role of deliberate moral practice by idealizing the natural as morally perfect. This article employs the framework of embodied cognition to present a novel interpretation of Taizhou moral philosophy and to address critiques regarding its views on evil and moral practice. It explores Taizhou’s holistic approach, integrating mind and body, self and others, to offer fresh insights into the balance between deliberation and spontaneity in moral practice. As a comparative and interdisciplinary endeavor, this article bridges Eastern and Western philosophies, connecting moral philosophy with empirical science. It aims to deepen understanding of Taizhou philosophy while highlighting its broader relevance for ethical behavior and moral reasoning in a global context.

Case Study Analysis on the Flood Mitigation Effects of Improving a Drainage System Using Low Impact Development Techniques

Low-impact development (LID) techniques aim to minimize the hydrological and environmental impacts associated with watershed development by preserving the natural state as much as possible, reducing impervious surfaces, managing stormwater on a small scale at the point of generation, and promoting decentralized stormwater management. In this study, the flood reduction effects of LID techniques were analyzed using PCSWMM by comparing traditional development methods in the Songsan Green City development project. In this process, the LID technique considers nonstructural methods of diversifying drainage directions and structural methods of introducing vegetated swales to improve the drainage system. The results showed that the LID approach, introduced to improve the drainage system, had a significant effect on reducing floods and inundation compared to traditional development methods. The results of this study suggest the potential of using LID techniques in structural and nonstructural approaches to improve urban flooding and inundation problems.

Planning literature education in schools based on literary ecology

This study aims to describe how ecological values that emphasize environmental awareness can be incorporated into literature education in schools. This research is qualitative, using an ecocritical and collaborative approach. The results show that literature serves not only to entertain but also to educate and can be used to raise awareness among students by integrating ecological values into literature learning. The application of these values can be observed through the teaching of reading and writing literary works with themes about the current state of nature, the beauty of nature if undisturbed by human activity, how humans can protect the universe, and the consequences of environmental destruction for the survival of humanity and all it encompasses. This application can be implemented by adapting reading and writing materials to literary ecology within the Learning Objectives Flow, which will be developed in the Lesson Plan (RPP). It includes the use of learning resources aligned with the materials in the RPP, employing relevant learning media based on literature-based ecological reading and writing materials, and designing effective teaching methods suited to the material. By incorporating ecological values into literature education in schools, it is hoped that students will gain ecological awareness to contribute to saving the earth from further degradation.

Forest Enclave Potential Assessment for Nature Conservation and Recreation in City with Dysfunctional Natural System

Forests are an important component of the natural systems of large cities. Their deficiency limits the proper functioning of these systems and creates a shortage of recreational places for residents needing contact with nature. This can be encountered in Rzeszów, a city in southern Poland with 200,000 inhabitants, which is characterised by the smallest forest area (2.8%) of all province capitals in the country. The natural state of small forest enclaves in this city has not been fully investigated. This has led to incorrect management and nature conservation policies. Therefore, the aim of this research conducted since 2015 was to recognise the potential for conservation and recreational functions using the concept of ecosystem services (ES) and ecosystem disservices (EDS), and to develop recommendations for the optimal use of these areas. This article analyses and compares 14 indicators related to ES and EDS of three out of five larger forest patches in the city. The results of this analysis indicate that the current method for protecting these valuable elements of the natural system does not correspond with their actual conservation potential. The application of the ES and EDS concepts to assess the nature conservation potential allowed us to determine it as high in two forest enclaves where such potential had not been indicated so far, and to identify the highest recreational potential in one of the investigated sites.

A novel multi-model feature generation technique for suicide detection

Automated expert systems (AES) analyzing depression-related content on social media have piqued the interest of researchers. Depression, often linked to suicide, requires early prediction for potential life-saving interventions. In the conventional approach, psychologists conduct patient interviews or administer questionnaires to assess depression levels. However, this traditional method is plagued by limitations. Patients might not feel comfortable disclosing their true feelings to psychologists, and counselors may struggle to accurately predict situations due to limited data. In this context, social media emerges as a potentially valuable resource. Given the widespread use of social media in daily life, individuals often express their nature and mental state through their online posts. AES can efficiently analyze vast amounts of social media content to predict depression levels in individuals at an early stage. This study contributes to this endeavor by proposing an innovative approach for predicting suicide risks using social media content and machine learning techniques. A novel multi-model feature generation technique is employed to enhance the performance of machine learning models. This technique involves the use of a feature extraction method known as term frequency-inverse document frequency (TF-IDF), combined with two machine learning models: logistic regression (LR) and support vector machine (SVM). The proposed technique calculates probabilities for each sample in the dataset, resulting in a new feature set referred to as the probability-based feature set (ProBFS). This ProBFS is compact yet highly correlated with the target classes in the dataset. The utilization of concise and correlated features yields significant outcomes. The SVM model achieves an impressive accuracy score of 0.96 using ProBFS while maintaining a low computational time of 5.63 seconds even when dealing with extensive datasets. Furthermore, a comparison with state-of-the-art approaches is conducted to demonstrate the significance of the proposed method.

Theory of Thomas Hobbes on the neccessity to move from the state of nature and form a state

This study demonstrated the theory of Thomas Hobbes on the necessity to move from the state of nature and form a state. Law is a prerequisite for ensuring peace, tranquillity and effective governance in a society. When law is in place, it fosters human beings' interaction with each other and creates a conducive environment for socio-economic empowerment. In the state of nature, according to Thomas Hobbes, there existed no government, no law, and nobody was above the other. There was no law, industry, civilisation, social life, economic and political order. If there was no law in place, then there was no morality. If there was no morality, then there was no justice or injustice. Life here was characterised by brutality, selfishness, and solitude and hence was short. The study was guided by Thomas Hobbes's political theory, which emphasises consent and consensus in the formation of government so as to move from the state of nature where life was unbearable. The study was library-based, and the researcher used a purposive sampling method to purposely sample three books that are inclined to materials related to Thomas Hobbes's political theory on the state of nature. The data was collected through reading texts, both published and unpublished. The location of the study was Chuka University Library. The study adopted a descriptive design and used a critical method that questions assumptions, examines the evidence, identifies biases, and strives for a deeper understanding of the state of nature and the necessity of forming a society. The study found that there is a need to have an organised society guided by law. The study recommended the need for equal distribution of resources.

Relevance of Thomas Hobbes's political theory in addressing the challenges facing the principle of public participation in Kenyan governance

This study sought to address the relevance of Thomas Hobbes's political theory in addressing the challenges facing the principle of public participation in Kenyan governance. Law brings order in the society, and it is a prerequisite for ensuring peace, tranquillity and effective governance in a society. Despite the principle of public participation being enshrined in the constitution, political leaders have not fully embraced it. The study was guided by Thomas Hobbes's political theory. This theory emphasises consent and consensus in the formation of government so as to move from the state of nature where life was unbearable. The study was library-based, and the researcher used a purposive sampling method to purposely sample four books that are inclined to materials related to Thomas Hobbes's political theory on the state of nature. The data was collected through reading texts, both published and unpublished. The location of the study was Chuka University Library. The study adopted a descriptive design and used a critical method that questions assumptions, examines evidence, identifies biases, and strives for a deeper understanding of the principle of Public participation under the constitution of Kenya. The study found that there is a need to have an organised society guided by law. The study recommended the need for the government to engage people in public participation so as to get their consent in developments and governance policies.

Application of SWAT to assess peatland forestry impacts on water quality

ABSTRACT Peatland drainage can affect the natural state of hydrological conditions and nutrient loading but is rarely included in catchment-scale models. To understand the gap, we aimed to use the soil and water assessment tool (SWAT) model to observe drained peatlands and their properties to predict nutrients and suspended solids (SS) in the peatland-dominated Simojoki catchment. We integrated drainage networks in SWAT to (i) identify the parameters for the drainage; (ii) determine annual loads and mean concentrations of SS, organic phosphorus (Org-P), total phosphorus (TP), organic nitrogen (Org-N), and total nitrogen (TN); (iii) understand spatial variation of nutrients and SS; and (iv) investigate the uncertainty ranges for the estimates. The calibrated SWAT model showed a 9.6% PBIAS between the simulated flow and the observations with low to medium loading variations for the water quality parameters. For Org-N and TN, the highest loading per year was at the downstream outlet, whereas for SS, Org-P, and TP, it was higher at the upstream outlet of the catchment. This approach of representing the drained peatland in SWAT indicated a maximum spatial distributed load in the peat soil in the clear-cut area and it can be beneficial in future hydrological modelling efforts in identifying the status of nutrients or SS.

Institutional Logic of Fragile States: Afghanistan and South Sudan in Comparative Perspective

ABSTRACT In the violence trap framework, ruling elites use rents to control contending elites who pose a violent threat. Political development results in transitions from a fragile state, wherein rents are tentative and personalized, to a basic natural state, and then a mature natural state, through standardization of elite privileges, consolidated state control of the political-military apparatus, and the enactment of a credible contracts regime. Accordingly, the institutional logic of fragile states is rooted in the incentives that undergird elite bounded rationality, transacting under highly personalized, tentative patronage networks. The paper addresses the question of why fragile states fail to develop into basic natural states. In doing so, it applies the violence trap analytical framework to illustrate the logic of the fragile state through a most different systems (MDS) comparison of Afghanistan and South Sudan. The main finding is that the institutional logic of the fragile state in the two cases is rooted in a lack of three necessary conditions: institutional incentives for broadening elite consensus, credible patronage agreements among different elite groups, and a consolidated state with specialized political and military functions.

Model-based estimation of heart movements using microwave Doppler radar sensor.

Heart rate is one of the most crucial vital signs and can be measured remotely using microwave Doppler radar. As the distance between the body and the Doppler radar sensor increases, the output signal weakens, making it difficult to extract heartbeat waveforms. In this study, we propose a new template-matching method that addresses this issue by simulating Doppler radar signals. This method extracts the heartbeat waveform with higher accuracy while the participant is naturally sitting in a chair. An extended triangular wave model was created as a mathematical representation of cardiac physiology, taking into account heart movements. The Doppler radar output signal was then simulated based on this model to automatically obtain a template for one cycle. The validity of the proposed method was confirmed by calculating the PPIs using the template and comparing their accuracy to the R-R intervals (RRIs) of the electrocardiogram for five participants and by analyzing the signals of eight participants in their natural state using the mathematical model of heart movements. All measurements were conducted from a distance of 500 mm. The correlation coefficients between the RRIs of the electrocardiogram and the PPIs using the proposed method were examined for five participants. The correlation coefficients were 0.93 without breathing and 0.70 with breathing. This demonstrates a higher correlation considering the long distance of 500 mm, and the fact that body movements were not specifically restricted, suggesting that the proposed method can successfully estimate RRI. The average correlation coefficients, calculated between the Doppler output signals and the templates for each of the eight participants, exceeded 0.95. Overall, the proposed method showed higher correlation coefficients than those reported in previous studies, indicating that our method performed well in extracting heartbeat waveforms. Our results indicate that the proposed method of remote heart monitoring using microwave Doppler radar demonstrates higher accuracy in estimating the RRI of the electrocardiogram while at rest sitting in a chair, and the ability to extract the heartbeat waveforms from the measured Doppler output signal, eliminating the need to create templates in advance as required by conventional template matching methods. This approach offers more flexibility in the measurement environment than conventional methods.

Выбор аналитической модели и количественных показателей для геоинформационного анализа устойчивого развития территориальных образований

Currently, there are no generally accepted algorithms for assessing, analyzing and forecasting the sustainable development of administrative-territorial units. The authors introduce the definition of this term, which implies the successful functioning of a human community over time carrying out economic activities without threats to its environment. Also, an analytical model for representation of its regional integrated indicator in the form of a vector with differential components, which characterize economic growth, environmental and social metrics, in a three-dimensional affine space, is proposed. Furthermore, we present a multiplicative criterion for assessing partial criteria of sustainable development efficiency and the basic expression for its parameters computation based on the set of economic, environmental and social ones, including such as the availability and quality of natural resources, regional labour resources, eco-factors, etc. The proposed vector model is based on the geoinformation approach and can be deployed within the framework of GIS of sustainable development for geo-analysis, modeling and mapping of natural resource potential and ecological state of intensively advancing territories, considering the dynamics of this process. Important properties of the geoinformation approach to assessing territorial entities’ forward growth, spatial and semantic scalability, are noted. In addition, the functional requirements and preliminary architecture of the core, modules, clients and layers of the related thematic geographic information system for the management, planning and forecasting the said indicator within the framework of digital economy are described

State Forests’ “Spend the Night in the Forest” Program in the Context of Education for Responsible Tourism in Poland

The aim of the article is to present the key elements of the State Forests’ “Spend the Night in the Forest” program as well as the selected results of its evaluation in the view of education for responsible tourism. The article is divided into two parts. The first, theoretical part, presents the assumptions of the idea of Leave No Trace outdoor ethics, which tally with the paradigm of education for responsible tourism. Its task is to develop the skills, knowledge and competences in the field of rational and responsible use of natural resources. At the same time, it lays the grounds for the “Spend the Night in the Forest” program. In the second, empirical part, the author presents selected results of the evaluation of the “Spend the Night in the Forest” program including demographic characteristics of its participants, their motivations, preferences regarding the choice of area, the way of organizing the camping, types of activities undertaken as well as assessment of the principles corresponding to the Leave No Trace idea. In addition, the article presents suggestions regarding the division of respondents into user groups. The cited results indicate that the respondents declared their willingness to take care of the forest as a common good and tried to educate and influence other tourists camping in a way inconsistent with the Leave No Trace principles. It can be concluded that the “Spend the Night in the Forest” program supports education for responsible tourism. By enabling the participants to experience nature in its natural state, it helps rebuild human relationship with nature. Moreover, the program serves the purpose of shaping public awareness that we all influence the environment and that we all are responsible for its current and future state.

Choosing reference land use for carbon and biodiversity footprints

Abstract Purpose Carbon and biodiversity footprints are increasingly calculated. However, little attention has been paid to the coherency of methodological choices and interpretation of the footprint results. This paper aims to clarify the coherency between the choice of reference land use and carbon and biodiversity footprints and discuss the challenges encountered. Methods First, we analyse features of reference land use options proposed in ISO 14067 (2018) i.e. business as usual, projected future, target, potential natural regeneration and historic baseline. Second, we discuss the connection between temporal scope and life cycle of land use. Third, we provide guidance on how to choose reference land use coherently. Fourth, we discuss specific issues related to carbon and biodiversity footprints and their relationship to reference land use. Finally, we provide conclusions and recommendations for further conceptual development. Results and discussion Choice of reference land use and determination of temporal scope of a study may significantly influence the assessment of carbon or biodiversity footprints. If the aim of a footprint study is to assess the effects of land use, reference land use should describe dynamically non-use of land. Thus, potential natural regeneration or continuation of natural state (if it is the starting point) of land is the coherent reference land use in this case. If the aim of a footprint study is to assess the effects of a decision to change land use or its management, reference land use should describe dynamically alternative use of land expected without the studied decision. Business as usual or projected future is a coherent reference land use in this case. Historic baseline or target reference land use may be useful in comparing the ecosystem value of the studied land use with a pre-set historic baseline or (policy) target. Conclusions We conclude that coherent choice of reference land use for carbon or biodiversity footprints depends on the goal and scope of a study. Beyond methodological coherency, issues related to the reliability and availability of appropriate data are relevant and vary between reference land use choices. However, difficulties in the assessment should not justify incoherent choices. We recommend that uncertainties are not overlooked but incorporated in the assessment and considered in the interpretation of the results. In addition, we recommend that key methodological choices, including the definition of the purpose of a study, chosen temporal scope and applied reference land use, should be clearly and transparently presented.

Label-free quantitative phase imaging and analysis of airborne pollen

Abstract Pollen morphology, involving the physical characteristics of pollen grains from seed plants during reproduction, plays an important role in plant biology, ecology, and evolution. High pollen concentrations in the air can degrade air quality and exacerbate respiratory conditions such as asthma. Understanding pollen morphology and its implications for air quality is significant for mitigating respiratory health risks. Conventionally, fluorescence microscopy is used for pollen imaging, but photobleaching, quenching, and phototoxicity affect the surface morphology and do not provide quantitative data on the pollen grains. For this study, we used bright field (BF) imaging and quantitative phase imaging (QPI), a label-free interferometric microscopy method, to look at differences in the shape of pollen. BF imaging provides information about the shape and size of the different pollens but has a limitation of low contrast. To obtain high-contrast images and quantitative data on the pollen grains without any exogenous agents, we employed QPI and BF imaging in the present study. QPI enables the extraction of detailed information regarding the cell wall, aperture, and thickness of pollen while also maintaining their natural state without the need for chemical treatments. In the present work, we sampled the ambient air from May 2023 to January 2024 on the IIT Delhi campus. Subsequently, QPI and BF imaging have been done for pollen identification and phase analysis of arboreal and non-arboreal pollen. Further, by utilizing the information obtained from BF microscopy and QPI, different species of pollen have been identified, and a pollen calendar has been prepared for exhibiting pollen season throughout the year. To the best of the authors’ knowledge, they have conducted the QPI of airborne pollen grains for the first time; this technique holds great potential for characterizing airborne pollens without the need for staining or sample preparation.
