Introduction

Use of acid/base is common in laboratories for experiments like titration and proper safety in their handling laboratory is necessary. In this chapter we will briefly discuss about the safety measures necessary to be adopted while using acids/bases in laboratory for any experiment.

Handling of Strong Acid/Base

There are four major points that need to be taken care of while working with strong acids or bases that might be quite harmful if any accident happens.

1. Protect Yourself

Wear a lab-coat and acid-resistant gloves: Always use lab-coat/apron and make it sure that the sleeves properly cover your arms. More importantly, use gloves made of acid-resistant materials and also wear shoes to protect your feet while wearing long-pants/jeans. Female with long hair, must tie her hair properly (with rubber band) to avoid any disturbance caused by appearance in between.

Wear safety goggles: It is important to wear safety goggles to protect your eyes using larger and fitting goggles that cover front as well as sides of your eyes. Always use properly fitting and adjustable goggles because smaller/ loose goggles may not protect the areas around your eyes against accidental acid spills and it may fall down from your face, if it is too loose.

Locate emergency wash area: There must be an emergency washing area nearby the work place or laboratory containing lab spill management kits. All the workers in the laboratory must be aware of using the kits and emergency plans.

Neutralize acid: Don’t panic even if an acid or chemical spill happens. Stay calm and act as quickly as possible. In case an acid spills, neutralize it by using sodium bicarbonate so that they can be cleaned and disposed safely. If acid comes in contact of skin, wash it off under running tap water but do not use/ apply sodium bicarbonate on skin.

Introduction

Measurement of pH of a solution and preparation of different types/strength of buffers are common practices in a laboratory, particularly in the Biochemistry and Molecular Biology laboratories. Therefore, in this chapter you will be acquainted with the procedures of measuring pH of a solution as well as preparation of some of the commonly used buffers in a laboratory.

Potential or Power of Hydrogen Ion (pH)

Measurement of pH of a solution is measuring the molar concentration of hydrogen ion [H+] in the solution, which is an indication of the acidity or basicity of the solution. The symbol pH stands for “power of hydrogen” and numerical value for pH is just the negative logarithm of the molar concentration of hydrogen ions [H+]. The ionic product of water (Kw ) is the basis for the pH scale. The total hydrogen ion concentration from all the sources and it can be experimentally measured.

The pH scale designates the concentration of H+ (and thus of OH−) in an aqueous solution, which ranges between 1.0 M H+ and 1.0 M OH−. The term pH is defined by the expression

Thus, the ionic product of water makes it possible to calculate the concentration of H+, with given concentration of OH−, and vice versa. The value of 7 for pH of a neutral solution is not an arbitrarily chosen figure; it is derived from the absolute value of the ionic product of water. A solution having pH greater than 7 is basic, and the concentration of OH− is greater than that of H+. A solution having a pH less than 7 is acidic.

Introduction

For agricultural applications as well as for research work, often we need to prepare solutions of different agrochemicals of varying strength, as per the requirements. Agrochemicals are used to help crop plants grow, produce, and protect them from biotic/abiotic stresses. Many of the agrochemicals (insecticides, herbicides, fungicides, rodenticides, molluscicides, nematicides, etc.) are used to protect the crop from insect pests and diseases. However, some of them (fertilizers and soil conditioners) are used to augment crop yield. While in the previous chapter (Chapter 8) we discussed about preparation of laboratory solutions, in this chapter we will briefly discuss about the preparation of different agrochemicals.

Agrochemical/agrichemical is a generalized term used for the chemicals applied in agriculture. In general, it also includes the feed-supplements used in f isheries and animal husbandry.

Agrochemicals

Fertilizers

Fertilizers are used to augment growth of crop plants and to mitigate nutrient deficiency in the soil. Fertilisers can be organic (containing natural substances, prepared through natural processes) and inorganic fertilisers (synthetic fertilizers, manufactured artificially using chemical processes using natural deposits, by chemical alterations).

Soil Conditioners

Soil conditioners include manure, livestock and leaf compost, peat that help making the soil in good condition. They are laid on the top soil and then mixed properly. They not only increase nutrient contents in the soil but also improve aeration and water holding capacity.

Introduction

In a research laboratory, we frequently need weigh chemicals and prepare different solutions of varying strength, as per the requirements. Accuracy in weighing and preparation of solution, with respect to weight/volume and strength, determines the success of experiment. In turn, the accuracy depends on weighing of solid chemical and/or measuring the volume of liquid chemical/making up the volume. In this Chapter, weighing of chemicals using appropriate weighing balance, preparation of solutions of different strength, their dilution, and precautions while preparing will be discuss in brief.

Weighing of Chemical

The primary method to determine the amount of chemicals to be used is weighing the chemical by using a balance.

In general, there are two types of balances to weigh chemicals in a laboratory:

1. Standard laboratory balance

2. Analytical balance

Standard Laboratory Balance

Generally, a standard laboratory balance is used for weighing a chemical when an error of ±0.02 g is acceptable. It is also used for pre-weighing, where approximate mass needs to be determined. Precise mass of the chemical is then determined using an analytical balance. Following are the steps in using a weighing balance in a laboratory.

Introduction

To accomplish experimentations in laboratories, sometimes we need microscope to test/validate our ideas/findings. A microscope is needed to examine objects which are very small which cannot be visualised by naked eyes. However, microscopic study requires some expertise in operating the microscope, particularly the sophisticated microscopes, as well as to prepare (peeling, sections, cutting, fixation, staining, dehydration, mounting, etc.) the sample, so that it can be appropriately examined for the anticipated details.

According to the scientific requirements different types of microscopes are used in the laboratories for research purpose. In this chapter, our aim is to acquaint you with the basics of using and handling of microscopes, particularly a compound microscope that is commonly used by the graduate and post graduate students for basic research.

Microscopy is often designated as the scientific investigation that is employed to review and analyse minute structures and objects using a microscope. The term “microscope” has been derived from ancient Greek words “micros” meaning “small” and “skopeîn” meaning “to look at or see,”.

Microscope

A microscope is a laboratory instrument used to examine objects (biological specimens) which are too small to be seen by the naked eye. The microscope must accomplish three tasks:

• Magnification- to provide a magnified image of the specimen.

• Resolution- to separate the details in the image.

• Contrast- to render the details clearly visible to the eyes.

Although we will tnroduce to you the different types of microscopes used for different speciments, our main focus is to discuss about compound microscope, which is commonly used in the laboratories. Compound microscope was developed around the beginning of 17th century.

Since mouth pipetting of liquid reagents in a laboratory is not advisable, different tools are needed for safe, easier, and precise dispensing of liquid reagents. This chapter is devoted to make you aware of the tools like vacupette and micropipette which can be used for the handling of liquid reagents in a safe and precise way.

Vacupette

Glass pipettes have been traditionally used by sucking liquid solvent/solution directly using mouth. For safety reasons, mouth pipetting is no longer permitted in a laboratory. Hence, to fill a pipette vacupette is used by placing it on the top of glass or plastic pipette. It acts as a device to create vacuum for filling reagent in the pipette as well as for releasing the reagent with mechanical regulation on the flow out of the liquid. Vacupette can be of different types.

1. Rubber Bulb Vacupette

Rubber bulb vacupette is often used to transfer (pump up and discharge) liquid using a pipette when a larger quantity of chemicals is to be transferred. Small/tiny rubber bulb is attached to glass/plastic pipette for drawing little amount of reagents. Small vacupette is used to precisely discharge smaller volume/ drops.

Handling of Vacupette

• Insert the top of a pipette in the bottom of the rubber bulb vacupette (Figure 6.1).

• Remove air from the pipette by squeezing valve “A” at the top of the vacupette while simultaneously squeezing the rubber bulb. The amount of air released depends on the size of the rubber bulb.

Different basic as well as advanced laboratory equipment need to be used in a laboratory while conducting experiments. Many of them like pH meter, laminar air-flow hood, viscometer, thermometer, magnetic stirrer, microwave ovens, incubators, sand-bath, water-bath, oil-bath, etc. are the basic and simple equipment which require to be used routinely while conducting experiments in a laboratory. However, basic knowledge of their operation, handling procedure, when to be used, how to be used, and more importantly what not to be done with it, etc. are essential for keeping them in serviceable condition as well as for the accuracy/precision in their operation. In this chapter, we will discuss about some of the routinely used laboratory equipment along, while some other sophisticated equipment will be discussed in other chapters.

pH Meter

A pH meter measures exactly the H+ concentration of a solution; thus indicates acidity or alkalinity of a solution with greater precision. Actually, it measures the difference in electrical potential between a pH electrode and a reference electrode, and display the results converted into the corresponding pH value. Electrode is the key part (rod-like structure, usually made of glass) of a pH meter, having a bulb at the bottom containing a sensor. The pH meters range from simple and inexpensive pen-like devices (portable/pocket pH meter) to complex and expensive laboratory instruments with computer interface (Figure 5.1).

Frequent calibration of a pH meter using the solutions of known pH (standard solution of pH 4.01, 7.00, 10.01, Figure 5.2), generally before each use, ensures the accuracy of the instrument. For very precise work the pH meter should be calibrated before each measurement. For normal use calibration should be performed at the beginning of each day. This is necessary because the glass electrode does not give a reproducible measurement over a longer period of time.

A variety of glassware like burettes, pipettes, measuring cylinders, flasks, separating funnel etc. are used for experimental purposes in a laboratory. All of these need to be used and handled correctly, otherwise the chances of experimental error and damage to the glassware increase significantly. Being made of glass, they need special care while washing and using in experiments because even a minor mistake in handling of glassware may result in breakage of the apparatus. With this precautionary note, let us discuss about some of the specific glassware used in the laboratories.

Burette

Burette is a long graduated glass tube with a stopcock at one end for delivering a known/desired volume of a liquid, especially in titration experiments. It contains a stopcock at the lower end and a tapered capillary tube as the stopcock’s outlet. The flow rate of liquid from the tub stopcock’s outlet can be controlled with the help of stopcock valve. Burette is used for measuring the volume of a solution/chemical added in a quantitative (titrimetric) estimation experiment.

Procedure of using a Burette

The burette reading must be noted before and after delivering the chemical/ solution from the burette. The difference in these two readings is the volume of the chemical/solution released out of the burette. The solution should be released slowly/drop-by-drop to avoid any experimental error/mistake. If the solution/chemical is allowed to pour out too fast, the wall of the burette will not drain properly and some liquid may remain sticking to the surface of the walls. Moreover, excessive amount of chemical may be released/dropped during the experiment, particularly during the titration experiment wherein we need to know the exact amount of acid/base needed to get neutralization point. Thus, any minor mistake may lead to get a faulty reading. The measuring capacity of a burette usually used in a laboratory is 50 mL.

Introduction

A variety of glassware, plasticware, and other apparatus are used for experimental purposes in a laboratory. They need to be washed, cleaned, dried, and sometimes sterilized before they can be used in the next set of experiments. Glassware needs special care of handling during washing, drying, sterilization, etc. because even a minor mistake in handling of glassware may result in its cracking/breakage and it may become unserviceable. All of these may result in a delay in experimentation if spare piece of the glassware is not available or it may affect serviceability of the associated apparatus.

A large number of glassware such as beaker, flask, measuring cylinder, burette, test tube, etc. are regularly used in a laboratory, which requires careful handling during the different stages of experiment as well as after completion of the experiment while preparing them for another set of experimentation.

Glass being a complex silicate, its properties depends on the type of silicate anions in the structure and the cations formed. Thermal properties of glass changes by the addition of boron oxide (B2 O3 ); hence, borosilicate glass is extensively used in the laboratories. With this brief background information, let us discuss about the necessity, procedures, and precautions during washing, cleaning, drying and sterilization of laboratory-wares. Figure 3.1 shows various advantages of using borosilicate glass in a laboratory.

Good laboratory practices require clean glassware, because an experiment may give erroneous result if dirty glassware is used at any step of the experiment. Hence, the glassware must be physically and chemically clean; and in many cases, it must be microbiologically clean or sterile. The commonly used glassware in a laboratory include test tube, measuring cylinder, pipettes, beakers, flasks, microscopic slides, etc.

Introduction

While experimenting with chemicals, sometimes we need to dry the chemical/ solution (solid, liquid or gas) using a process like evaporation or distillation, mainly to remove water or different solvents. Drying is the process of evaporation or distillation to remove water/solvent from a solution, solid or even from gas. Generally, a drying agent (usually an anhydrous inorganic salt) is used for this process, which reacts with the water (present in the chemical/ solvent to be dried) to form a hydrate. For example, anhydrous MgSO4 is one of the drying agents. The drying agents are recognized by their capacity (the rate at which they absorb water) and their intensity (the amount of water left behind in the solvent at equilibrium). No chemical reaction or change in phase occurs during the drying process.

Type of Solvents

Apart from water (a universal solvent), there are three families of organic solvents used in laboratories.

1) Oxygenated solvents: Alcohols, Ketones, Glycol ethers, Glycol esters, etc.

2) Hydrocarbon solvents: Aliphatic and Aromatic hydrocarbons.

3) Halogenated solvents: Chlorinated hydrocarbons.

Introduction

For proper and efficient experiment to be conducted, experimenters need so many chemicals to deal with. This includes different acids, base, salt, different kind of indicators and so on. Some of these chemicals are safe for health, but some of them are dangerous to health when come in close proximity to our body while some of the chemicals cause health issues on inhaling. These may cause improper functioning of some of our physiological activities. Acids and bases are very dangerous for our tissues when come in our contact. These may cause serious respiratory problem in addition to injuries on coming to our contact. Some chemicals are exploratory yet they may cause even death of the person working with them in laboratory. Therefore, mere use of the chemicals in laboratory is not only the objective of the experimenter. The person working in laboratory should also be concerned about the proper use and handing of the chemical while working with it. Thus, every researcher of an institution who has to work with chemicals in a laboratory should be made aware about the chemicals to be used in the laboratory and the consequences if any mishandling of a laboratory chemical occurs. Not only these, suitable precautionary measures should also be known to the researcher along with ensuring the availability of the required safety equipment/installations. Hence, a proper understanding of the ways of handling of chemicals in a laboratory is of prime importance for the personals like you who are working or have to work in laboratory.

Safe Handling of Chemicals in Laboratory

Safe use/handling of chemicals in laboratory include minimized exposure to chemicals, maintaining safety data sheets, proper labelling, storage, segregation, and transport of chemicals for personal hygiene.

As the present study draws to a close, it opens up a myriad of possibilities for future research and exploration in the field of the present study. The insights gained and the findings presented in this thesis may provide a foundation for building upon and extending the existing body of knowledge. By identifying key areas that require additional attention and offering suggestions for future studies, this section of the chapter aims to inspire and guide researchers in their pursuit of enhancing our understanding and driving progress in this dynamic and evolving field.

The present study leaves behind the following domains which may be researched out in future:

1) The present research can be replicated with varied geo-spatial situations viz., in different locations and settings, with different respondents, with spatio-temporal expansion and methodological innovation.

Despite the meticulous methodology and extensive analysis employed throughout this research project, it is crucial to acknowledge and address the limitations that arose during the study. By recognizing these limitations, we not only ensure a transparent evaluation of the research process but also shed light on potential areas for future investigations to refine and expand upon the findings.

In this section of the chapter, the limitations encountered in this thesis are highlighted as follows:

7.1 Summary

Climate change is a complex global phenomenon that poses significant challenges for agriculture including uncertainty about future weather patterns, soil conditions, and other environmental factors. Farmers are facing the difficult task of interpreting and responding to these changes in order to maintain their livelihoods and ensure food security for growing populations. In this context, mental modelling has emerged as a useful approach for understanding how farmers interpret and respond to climate change. Mental models are cognitive representations of how individuals understand and make decisions about complex systems, and can be used to identify key drivers of behaviour and decision-making.

The present study has explored the social, ecological, and economic factors that influence farmers’ mental models on perception of climate change, level of uncertainty and trend of agricultural change in the selected study area. It argues that farmers’ mental models are shaped by a range of factors, including their own experiences and observations, social networks and interactions, access to information and resources, and broader economic and political contexts. The present study has also highlighted the role of uncertainty in shaping farmers’ mental models and decision-making. Uncertainty about the future impacts of climate change can create significant challenges for farmers, as they must make decisions based on incomplete information and uncertain predictions.

The current research work was carried out in the new alluvial zone which is one of the agro-ecological regions in the state of West Bengal. To conduct the study, three villages located in the Haringhata block of Nadia district were chosen randomly. A total of 90 farmers were selected with 30 respondents each from the villages of Kastadanga, JalkarBhomra and Subuddipur. Initially a list of contact farmers was collected from the Kastadanga SKUS and few contact farmers were selected randomly from the list. Afterwards Snowball sampling method was followed to select respondents.

This chapter focuses on presenting empirical findings from data analysis to provide sufficient interpretation so to draw reliable conclusions. To enhance and complement the textual contents of the study, tables and models are frequently utilized. Additionally, the discussion serves to contextualize the study’s findings and establish connections with the research work.

The research methodology constitutes a comprehensive and well-structured plan of action for conducting the investigation and serves as a blueprint for the research process. Its purpose is to gain an understanding of the underlying concepts, methods, and techniques employed to define the study, gather relevant information, analyse data, and interpret the findings, thereby revealing concrete evidence and formulating theories.

In this chapter, an in-depth exploration of the research methodology is undertaken 
to comprehend the concepts, methods, and techniques employed for designing the 
study, gathering data, conducting data analysis, and interpreting the results. To 
facilitate clarity and ease of comprehension, the chapter has been divided into the 
following sub-headings:
 1. Research Design
 2. Locale of research
 3. Pilot study
 4. Sampling Design
 5. Variables and their Empirical measurement
 6. Methods of Data collection
 7. Preparation of Interview Schedule
 8. Item analysis and Expert’s rating for devising scoring technique for variables
 9. Pre-testing of Interview Schedule
 10. Data Processing and Analysis for FCM
 11. Statistical Tools used for Data Analysis
 12. Software used for Data Analysis 5.1. Research Design
A research design provides a structured approach for researchers to answer their research questions in an unbiased, precise, and cost-effective way. It establishes 
a framework for testing relationships between variables and ensures that the 
research is going on right direction. There are various types of research designs available, and the current study uses the descriptive and diagnostic research design. 
Descriptive research design is used to collect accurate and relevant information 
about the current state of a phenomenon, and to draw valid and generalized 
conclusions wherever possible. 

The research setting provides specific details about the location where a study is conducted. This study area typically encompasses a particular geographical region, such as a state, district, block, or gram panchayat, chosen according to the research requirements. The researcher must have a thorough understanding of the locality, including its communication methods, in order to effectively access all parts of the region for data collection.

In social science research, a clear comprehension of the characteristics, attitudes, and behaviours of the individuals within the study area is essential. Without this understanding, accurately conceptualizing, perceiving, and interpreting data becomes challenging. To obtain a comprehensive understanding of the implications and behavioural intricacies of the local people representing a broader community in the referenced study area, researchers must have a solid grasp of these factors. Therefore, this chapter critically analyses the socio-demographic background of the residents in a rural setting.

The term “research setting” denotes the context in which research inputs and elements are absorbed, interacted with, and mutually contribute to the system’s overall performance.

The research setting is crucial because it shapes and influences the interactions of various factors and components. Therefore, conducting a study on how farmers perceive persuasive issues and other topics requires a local context that takes into account the unique natural environment, demographics, crop ecology, institutional framework, and socio-cultural factors. For example, when writing a paper about the social behaviour of chimpanzees, it is important to include details about the research setting. This may include information such as where the chimpanzees were studied (in the wild or in captivity), the number of chimpanzees that were observed, whether they were part of the same social group, the geographic location, the time of the study, the season/weather conditions, the availability of resources such as food, water, and shelter, and any environmental factors that were present. There are two types of research settings: macro and micro. The macro research setting encompasses the entire state, while the micro research setting focuses on specific districts, blocks, or village peripheries. The aim of this approach is to understand the study environment from broader perspectives using the state as a reference frame and the district and block profiles as units of in-depth analysis.

The Review of literature is a systematic, explicit and reproducible method of identifying, evaluating and synthesizing the existing body of a completed and a recorded work produced by researchers, scholars and practitioners. The Review of literature is also a resource paper which includes the current knowledge including substantive findings as well as the theoretical and the methodological contributions to a particular topic. These are available mostly in academic and scholastic journals.

Review of literature provide the basics for research in nearly every academic f ield. This chapter is an extensive survey of all past studies relevant to the field of investigation which gives knowledge of what others have found out in the related field of study. In any scientific investigation or research, a comprehensive presentation of the review of literature is a statutory requirement.

The aim of review of literature is to highlight what has been done so far in the field of interest and how our findings are related to earlier research.

Its main functions are to develop a better understanding of the problem to be investigated, delineate a new area of study and avoid unnecessary duplication, decide on the tools and techniques to be adopted including developing some new ones and also to relate the present study with the previous ones by finding out the areas of agreement and disagreement.

The review of literature may

(a) Indicate the following by providing referential inputs – Approaches, Methods, Variables used, Statistical procedure, Expected results.

(b) Provide theoretical background to the study.

(c) Help to justify how the findings are related to the body of knowledge in the f ield of research.

(d) Establish a link between what we have proposed to study and what has already been found. It helps us to refine the research methodology.

In the context of a thesis, theoretical orientation refers to the conceptual or theoretical framework or perspective that informs and shapes the overall approach and analysis of the research (Natalie, 2022). It involves selecting and adopting a specific set of theories, concepts, or models that provide a foundation for understanding and interpreting the research topic. The theoretical orientation helps to guide the methodology, and provide a coherent framework for organizing and analysing the data.

Theoretical orientation in a thesis serves several purposes. It helps to establish a theoretical basis for the study, providing a context for the research and connecting it to existing knowledge and theories in the field. It also helps to guide the selection of appropriate research methods and data analysis techniques. The theoretical orientation shapes the overall structure and content of the thesis, ensuring that the study is grounded in relevant theories and concepts and contributes to the existing body of knowledge. By adopting a specific theoretical orientation, the researcher can provide a clear and systematic framework for understanding and interpreting the findings of the study. This orientation also helps to establish credibility and validity for the research, as it demonstrates the researcher’s awareness of and engagement with the existing theoretical perspectives in the field.

This chapter addresses crucial terminology and concepts essential for effectively communicating the ideas of the current study. It lays the groundwork for empirical investigation and aids in the selection of predictor variables. Additionally, this section involves a scholarly and theoretical exercise that influences the operational definition and content of the research. It combines conceptual inputs, axiomatic inputs, logical discussions, and the pursuit of knowledge to construct a theory that aligns with the research objectives and designs.

Climate change is a complex and dynamic phenomenon that has significant impacts on agriculture, especially in terms of uncertainty and variability. Agricultural dynamics refer to the various factors that affect agricultural production, including climate, soil, water availability, pests, and diseases, as well as market forces and government policies. Climate change has significant impacts on agricultural dynamics. Variations in temperature, patterns of rainfall, and occurrences of extreme weather can influence crop yields and livestock production in both beneficial and detrimental ways (UCAR, 2021). The effects of climate change on farming can differ based on the geographical location and the specific agricultural practices employed (Wikipedia Contributors, 2019). For example, in some areas, increased rainfall may lead to increased crop yields, while in other areas, droughts may lead to crop failures and loss of income for farmers. Additionally, rising temperatures can cause reduced crop yields and decreased quality of some crops.

Uncertainty is a term used to describe a situation where there is a lack of information, knowledge, or predictability about a particular outcome or event. In agricultural dynamics, uncertainty can refer to a range of factors that can affect the production, distribution, and consumption of agricultural products. One of the most significant sources of uncertainty in agriculture is the weather. The productivity of crops can be significantly influenced by weather conditions, including rainfall and temperature and farmers need to effectively adjust their agricultural practices to adapt to these changing weather patterns (Guntukulaand Goyari, 2020). For example, droughts or floods can reduce crop yields, while frost or hail can damage crops(Lamaoui et al., 2018).

The social, ecological and economic interpretation of climate change by farmers involves understanding the interactions between the natural environment, social systems, and economic factors (Spash, Clive L, 2011). Farmers need to consider these interactions when making decisions about their farming practices. For example, changes in climate can affect the availability of water, soil fertility, and crop yields, which can in turn affect social and economic factors such as food security and income. Farmers need to take into account the wider consequences of their agricultural practices on society and the environment which includes considering the impacts on biodiversity, ecosystems, and human well-being (Warsaw et al., 2021).
