Principle of ICP Optical Emission Spectrometry

The ICP is a partially ionized gas (mostly Ar) plasma produced in a quartz torch using a 1–2.5 kW radio frequency power supply. Samples are typically introduced into the center of the plasma as aerosols. Compared to the atomic absorption spectrophotometers, in which the excitation temperature of the air acetylene flame measures 2000–3000 “K, the excitation temperature of the argon ICP is 7000–10,000 K, which efficiently excites many elements. The solution for analysis is carried by a peristaltic pump through a nebulizer into a spray chamber, where aerosol is produced by the argon gas. The aerosol thus generated is directed into the central channel of the plasma. The plasma in ICP is generated at the end of a quartz torch by a water-cooled induction coil through which a high-frequency alternate current flows. Consequently, an alternate magnetic field is induced, which accelerates electrons into a circular trajectory. Due to the collision between the argon atoms and the electrons, ionization occurs, giving rise to stable plasma. At the core of argon plasma, the temperature is sustained at approximately 10,000 K, where aerosols are quickly vaporized. Subsequently, atomization and ionization of the sample analyte elements take place. Due to the thermic energy taken up by the electrons, they reach a higher “excited” state. When the electrons drop back to ground level, energy is liberated as light (photons). Each element has its own characteristic emission spectrum. By means of an Echelle grating, a prism, and a focusing mirror, these emitted photons at various frequencies are captured simultaneously by the suitable detectors. The wavelength of the photons can be used to identify the elements from which they originate.

Increased importance of research publications, impact factor and citations as metrics in evaluating science and assessing the quality of research is driving unethical practices too in research and publications. Adding to that, limited access to research publications, exuberant subscription charges, heavy article processing charges and several other transboundary science and technology issues are further dividing the scientific community which is severely impacting the progress of the Nation (Pathak, 2025). The National Academy of Agricultural Sciences (NAAS) journal rating system serves as a cornerstone for researchers in India, particularly in the domain of agricultural sciences. Its significance lies in providing an accessible and systematic framework for evaluating the quality and relevance of academic journals. This chapter explores avenues for enhancing the NAAS journal rating methodologies to ensure greater accuracy, inclusivity, and ethical rigor in the assessment process. By integrating global best practices, incorporating diverse metrics, and addressing emerging challenges in the academic publishing landscape, the proposed framework aims to make NAAS ratings more robust and globally competitive. To enable universal access to scholarly scientific literature, under Aatmanirbhar Bharat it would be appropriate to strengthen our own Indian Journals to compete globally in the long run. In this regard, NAAS rating of Agri-journals has been a progressive step and NAAS should continue to upgrade its evaluation mechanism. The Professional Association of Agricultural Societies (PAAS) and NAAS partnership in upgrading of publications in Indian society journals should be encouraged.

Introduction

Non-coding RNAs (ncRNAs) are RNA molecules that do not code for proteins. They are transcribed from DNA and can be categorized into two main types: long non-coding RNAs (lncRNAs) and small non-coding RNAs (sncRNAs). While sncRNAs are shorter than 200 nucleotides, lncRNAs are usually longer than 200 nucleotides. Non-coding RNAs have been found to play important roles in a variety of cellular processes, including gene expression, cell differentiation, and development.

Whole blood, plasma, serum, and blood transfusions are critical life-saving therapies in veterinary medicine. They are used to restore blood volume, correct anemia, provide clotting factors, and address protein deficiencies in various disease conditions. This chapter discusses their administration doses, species-specific considerations, and disease conditions where these fluids are essential.
Key components of blood therapy
1. Whole blood: Contains red blood cells (RBCs), plasma, clotting factors, and platelets.
2. Plasma: The liquid portion of blood with clotting factors, albumin, and immunoglobulins but without RBCs and platelets.
3. Serum: Plasma without clotting factors.
4. Packed red blood cells (pRBCs): Concentrated RBCs used to treat anemia without volume overload.

Materials and Reagents Required
1. Fixative- cold acetone or methanol
2. Ethanol – 70%, 90% and 100% for rehydration and dehydration
3. Xylene for clearing
4. Washing buffer (phosphate buffer saline)- PBS
5. Hydrogen peroxide – for endogenous peroxidase blocking
6. Normal horse serum or any other serum: 2.5% horse serum or any other serum can be used to block non-specific epitopes.

9. Peroxide substrate kit—Immpact NovaRed (cat no. SK-4850; Vector Laboratories, NY, USA) for developing a red color signal (Figure 22; right panel).

In the world of academic publishing, Article Processing Charges (APCs) have emerged as a significant barrier, particularly for researchers from countries with limited resources like India. These charges, often levied by open-access journals to cover the costs of peer review, editing, and dissemination, have created a financial divide that impedes equitable access to scholarly communication. This chapter delves into the multifaceted challenges posed by APCs and outlines potential solutions to address the inequities they perpetuate (Fig. 6.1).
6.1. The Burden of Article Processing Charges
The financial burden of APCs is disproportionately felt by researchers in developing nations. Many prestigious open-access journals charge APCs ranging from $1,000 to $5,000 or more per article. For researchers in high-income countries, these charges might be manageable, supported by robust institutional funding or grants. However, for their counterparts in countries like India, where research funding is limited and often tied to modest institutional budgets, such costs are prohibitive. The disparity in income and currency exchange rates further amplifies this challenge. A charge of $2,000, for instance, could equate to several months’ salary for a researcher in India, compared to a fraction of that amount for a researcher in the United States or Europe.

The term available phosphorus (P) refers to the inorganic form, occurring in soil solution, which is almost exclusively ‘orthophosphate’. The available P is considered to be a fairly good indicator/measure of the P supplying capacity of a soil. A knowledge of available P content of soils is important for determining its critical limit , based on soil-test-crop response calibration study.

Principle

In soil, phosphorus exists in the form of various types of orthophosphates. A very small fraction of these is available to plants at a given time. Available phosphorus content of soil consists mainly of Ca-P, Al-P and Fe-P. In the neutral and alkaline soils particularly, Ca-P is the dominant fraction. Organic –P fraction is also considerable amount, but is usually not include in the determination of available phosphorus. A large number of extractions, buffer solutions, acids and chelating agents have been suggested for available phosphorus from time to time. However, no single extractant appears to be suitable for all types of soils. Two types of extraction methods are more popularly adopted. Under acidic soil conditions, Bray No.1, which involves soil extraction with a solution consisting of 0.003 N NH₄F and 0.025 N HCl is widely followed. The fluoride complexes Al and Fe in soil, thus releasing some bound p besides the easily acid soluble P (largely Ca-P). This extraction is suitable for soils containing less than 2% calcite or dolomite because in calcareous soils, carbonates quickly neutralize the acid, resulting in less extraction of P.

Fishing is the most energy-intensive food production method in the world today and depends almost completely on internal combustion engines based on oil fuels. Energy is spent during the design, construction and operation of vessels. Energy loss can take place during different stages such as design, construction, operation and maintenance of boats and at harbor.

The energy costs for a particular fishery is determined principally by the technology in use, the local economic conditions, including taxes, subsidies, labour cost and operational cost. (O. Gulbrandson, FAO, 2012)

Only about one-third of the energy generated by the engine reaches the propeller and, in the case of a small trawler, only one-third of this is actually spent on useful work such as pulling the net.

The approximate distribution of energy created from the burning of fuel.

Amaranthus is an important leafy vegetable and is grown all over the Indian subcontinent. Amaranthus tricolor Linn and A. blittum Linn. are the common varieties cultivated. These herbaceous annuals are a rich source of proteins, vitamins A and C, and iron. The foliage is a good source of calcium, iron, and vitamins A, B, and C. In contrast, grains are good sources of important amino acids, particularly lysine, and are rich in dietary fibre, calcium, and minerals such as iron, magnesium, phosphorus, copper, and manganese. It enhances the body’s immune system and antioxidant status while lowering blood pressure and cholesterol. Fresh leaves and tender stems are used as vegetables. Production of amaranthus is affected by the incidence of pests. Cultivated amaranth is currently infested by a total of 92 different insect pests. (Rajeshkanna et al., 2017) among which the leaf webbers and amaranthus stem weevil are the most important pests.
Biology: Black moth with dark brown wings bearing white wavy markings on wings. Eggs are laid singly on leaves. Egg period 3 to 4 days. Larval duration will be completed within a period of 2 weeks. Pupation occurs among the leaf webbings and pupal duration lasts for 10 days. Several larvae can be seen inside each leaf web.

Obesity in pets is a growing concern and can lead to several health issues, including diabetes, arthritis, cardiovascular problems, and decreased lifespan. Preventing obesity in dogs, cats, and horses requires a balanced dietary regimen, regular exercise, and monitoring of body weight. Here is a comprehensive guide to recommended dietary regimens and formulated diets, along with the proportion of ingredients suitable for each species.
Prevention of obesity in dogs
Dietary regimen
Caloric control
Dogs require a controlled-calorie diet to prevent excess weight gain. The number of calories should be adjusted based on the dog’s age, breed, activity level, and current body weight.
Meal frequency
Feeding dogs smaller, more frequent meals instead of free-feeding helps manage portion control and prevents overeating.
High fibre diet
Fibre promotes satiety without adding significant calories. Including adequate amounts of fibre helps prevent obesity.
Low-fat diet
High-fat diets can lead to quick weight gain. A diet lower in fat content but with sufficient essential fatty acids helps prevent obesity while maintaining overall health.

Background
Cells are the basic unit of life. The morphology of cells describes their structural framework. It refers to the morphological features of the cell(s). It comprehends the various shapes and sizes in which cells function. Thus, the shape and size of the cell and the number of cells indicate their functional status. Hematological diagnostics requires the proper assessment and valid classification of cells for final diagnosis and prognosis. Clinicians, patients, and diagnosticians are all concerned with achieving a definitive specific diagnosis employing a single investigative test. The utilization of different cytological examinations from different organs gives adequate indicative data that leads to treatment outcomes.

21.1 Introduction
Khoa, as well as mawa or khava, is a partially dehydrated whole milk product that is produced by perpetually heating milk in a karahi over a direct fire while stirring and scraping it with a khunti until it reaches a semi-solid consistency. The pan is removed from the fire once the desired consistency is obtained, and the contents are transformed into a solid mass known as khoa pat. “Khoa is produced by rapid drying cow, buffalo, goat, or sheep milk, or a combination thereof, and must contain a minimum of 20% milk fat.The product is produced by heat desiccating milk to 65–69% solids in an open pan. Khoa has been utilised as a foundation for Indian desserts for centuries. Milk traders and halwais prepare it according to the conventional procedure. You typically require five times the amount of milk content.

21.2 Classification
There are three primary varieties: “pindi” for burfi, “dhap” for gulab jamun, pantooa, and other delicacies, and “danedar” for kalakand. Khoa production has been the most straightforward technique of preserving milk produced in rural areas during the flood season. Pindi, dhap, and Danedar are the three primary varieties of khoa that are prepared throughout the country. Khoa is the foundation for a diverse array of Indian delicacies, such as gulab jamun and other dishes.

The Tea mosquito bug : Helopeltis antonii : Miridae

The host range of this bug also includes tea, neem, moringa and guava. The attack can cause inflorescence blight, terminal drying of young shoots and heavy yield loss. The adult is a reddish brown bug with black head, red thorax, and black and white abdomen. The easiest identifying character for this pest is a pin like process on the scutellum mid dorsally on the thorax. It is reddish brown, erect and knobbed, and would seem as a pin inserted into the scutellum.

ABSTRACT

The coastal zone is environmentally sensitive and economically valuable, which has great attention from researchers especially from geoscientists. Coastal zone has great threat from pollution and natural calamities like cyclones, flood and tsunami. Natural calamity is a frequent phenomenon over coast. Therefore, it is very essential to monitor the changes over coastal ecosystem and geomorphic features like beach, shoreline and sand dunes. In this case, one of the basic requirements in managing and monitoring these features is the topographic data. The recently emerged technique of Airborne Altimetric LiDAR provides accurate topographic data. It is in preparatory stage in India. By this technique, we can collect the data at high speed when disaster happens. This paper attempts to provide a general overview of the role of LiDAR in coastal management.

The term nanotechnology was coined by Prof Taniguchi, Japan in 1974 during conference of the Japanese Society of Precision Engineering. Nano technology is a domain of scientific activity oriented on synthesis, characterization, application of devices and materials and technical systems which functions at nano structures having 1 to 100 nm size. Prof R. Feynman American Physicist and Nobel Prize winner was the first person pointed out the importance and promising outlook for nano particles during his lecture entitled “There’s Plenty of Room at the Bottom. An Invitation to Enter a New Field of Physics,” delivered on December 29th 1959 at the California Institute of Technology. He pointed out that “... when we have some control of the arrangement of things on a small scale we will get an enormously greater range of possible properties that substances can have, and of different things that we can do ... The problems of chemistry and biologycan be greatly helped if our ability to see what we are doing, and to do things on an atomic level, is ultimately developed”. Later scientists realized the potential of nano particulate materials during the last decade has tremendous advancement in nano research. Governments and private sectors of the world invested huge sums to reap the benefits from novel applications of nano materials.

Nanotechnology: The principle of nano technology is that the material with known properties and functions at normal size exhibit different behaviour and functions at nano scale. By decreasing the size of the material the surface area per unit material will increase enormously and this helps greater interactions with reactive sites. Nano technology implied that the process of fabricating and/ or controlling the material sized between 1 to 100nm.
