Abstract

The electromagnetic processing instruments such as microwave is very commonly used at house hold level, hence understanding the behavior of food as well as factors affecting its dielectric properties becomes important. Dielectric properties (DEP) play an important in electromagnetic processing of food products and mainly depend upon the moisture content, physical properties, composition, temperature and power applied. Different methods have been used to determine the DEP of food material including parallel plate, coaxial probe, resonance cavity, transmission line and free space method. The selection of these methods is again based on several factors such as type of materials, accuracy of measurement, the scope of the research, frequency range, availability of equipments and resources. Present study thus summarizes the importance of DEP of food, influencing factors and the different measurement techniques.

Ornamental Plants are a real attraction to the aquarium tank. While some plants are both ornamental and functional, people usually use the term “ornamental plants” to refer to plants which have no value beyond being attractive, although many people feel that the attractive value itself is quite enough. They provide optimal habitat for the fishes especially for the fry (baby fishes). It maintains the ecosystem of the aquarium tanks by providing good oxygen, food and also acts as a good hiding place for the baby fish. Mostly all aquatic plants are very easy to grow and care. They are always good for gold fish and other similar fishes. There is a huge variety of plants. Ornamental plants are grown for decoration, rather than food or raw materials. They are most often intentionally planted for aesthetic appeal. However, ornamental plants also serve some less obvious uses such as for the purpose of fragrance, for attracting wildlife and for cleaning the air. Ornamentals encompass a wide array of plants. Commonly, ornamental plants are grown for the display of aesthetic features including: flowers, leaves, scent, overall foliage texture, fruit, stem and bark, and aesthetic form. The concept of ornamental plants is used for decorative purposes in aquariums, gardens, home gardens, landscape design projects, squares, parks etc.

Aquatic plants predominantly grow in water. They vary greatly in type, with some being quite similar to common land plants while others are quite different. Aquatic plants can be commonly classified into four types: algae, floating plants, submerged plants and emerged plants. Aquatic plants live in water. This means that they require being submersed to survive or that they can only grow and thrive in water. Many aquatic plants can tolerate being emerged, meaning they’re out of the water for short periods of time, but require immersion in water for long-term survival.

There are some plants that simply can’t tolerate being emerged at all, but this is rare. These plants can only live when fully immersed in water. Most macro- algae require total submersion in water for the span of its entire life. Most aquatic plants, however, have roots underwater but can only grow or flower in a partially emerged state. All plants, aquatic and otherwise, require sunlight, soil, gases and water to survive. Plants make their own food via the process of photosynthesis; this means that they need a source of energy to drive this biochemical process, and the sun provides a perfect one. Plants can carry on for periods without sunlight, just as animals can live on stored fuel for a while in times of need. The soil offers a place for the plant’s roots to take hold.

Air contains large amounts of the carbon dioxide gas (CO2), plants need to power photosynthesis, but aquatic plants have evolved to draw in CO₂ that is dissolved in water in relatively small amounts. Finally, plants need water to combine with the CO2 to complete photosynthesis by generating oxygen and glucose.

1. Introduction
Omega-3 fatty acids are a vital group of polyunsaturated fatty acids (PUFAs) recognized for their complex chemical structure, which is characterized by multiple double bonds within their hydrocarbon chains. This unique arrangement not only influences their physical and biochemical properties but also underpins their essential roles in various biological processes across a wide range of organisms. Omega-3 fatty acids are categorized into three primary types: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). While ALA is predominantly found in plant sources, such as flaxseeds, chia seeds, and walnuts, EPA and DHA are primarily sourced from marine organisms, particularly fish and algae.
1.1 Importance of Omega-3 Fatty Acids
1.1.1 Nutritional Significance in Aquatic Organisms
In fish nutrition, omega-3 fatty acids are indispensable for promoting optimal growth, development, and overall health. These essential nutrients contribute to a multitude of physiological processes, including:
1. Cellular Structure and Function: Omega-3 fatty acids are integral components of cell membranes, influencing their fluidity and permeability. This is crucial for maintaining cellular integrity and facilitating the transport of nutrients and signaling molecules across membranes.

Introduction

Sugarcane based production system has to go a long way to turn hightech because of the existing technological gap in the irrigated agroecosystem. This has been realized more in the recent studies undertaken by social scientists. All the crops associated with the sugarcane based production need varietal introduction as well as the adoption of relevant crop management practices. Since the possibility of increasing area under sugarcane is remote in view of emerging low input high value crops, the projected target of 420 million tonnes by 2020 AD has to be achieved by enhancing the cane productivity and sugar recovery concurrently. The full exploitation of the existing improved sugarcane production technologies and development of a package of agro-techniques in the changing scenario of sugarcane based production system suiting to the socio-economic conditions of the farmers is as such the only master key to unlock the yield potential of sugarcane.

Meat cutting and fabrication is a skilled process in which separation of carcass into wholesale primal cuts is done to facilitate meat trade requirements, consumer preference and easy handling to the butchers. The person engaged in cutting and fabrication of carcass cuts must be skilled and expert in their job. He/she must have the expert knowledge of carcass configurations and location of retail cuts in animal carcasses. To obtain good quality retail cuts, carcass should be essentially chilled and temperature of meat cutting room should be 15-20oC with relative humidity of about 80%.

Meristematic Tissues

These are composed of cells that are in state of division or retain the power of dividing. These cells are essentially alike and isodiametric. They may be spherical, oval or polygonal and their walls thin and homogeneous; the protoplasm in them abundant and active with large nuclei, and the vacuoles small or absent.

Classification of Meristems

Meristems are classified in different ways on the basis of certain factors.

A) According to their origin and development

1. Promeristem or primordial meristem

2. Primary meristem and

3. Secondary meristem.

Red Rot
Diagnostic Symptoms
• Practically all above ground parts are affected, but stalks are the main targets of stack.
• Spindle leaves (third or fourth)starts drying.
• Further stalks becomes discolored and hollow.
• Diagnostic symptom is th formation of red streaks, interrupted by white patches , inside the stalk.This can be seen by splitting the stalks longitudinally.
• White patches are characteristics of disease, not found in other stalk rots.
• After splitting opened the diseased stalk, a sour smell due to conversion of glucose to alcohol.
• Red longitudinal lesions are also seen on the mid ribs of the leaves on which black color fruiting body (Acervuli) are formed (Fig.1).

Guava, Psidium guajava L., belongs to the family Myrtaceae, which comprises 3,000 species under 80 genera. It is well-distributed in the tropical and subtropical regions of the world, especially in South America, Asia and Australia. The genus Psidium has about 150 shrubs and P. guajava is wellknown and grown worldwide. The flower of guava is self-pollinated; cross pollination, however, is estimated to be around 35% and pollination mainly carried-out of by bees and other insects. Therefore, seed multiplication will result in genetic heterogeneity that can be observed in orchards and plants in the same orchard. Therefore, seed propagation in commercial orchards to increase productivity is not recommended. The methods of vegetative propagation have been studied for the purpose of the production chain. In addition to the propagation structure, the costs of new technologies must also be taken into account.
Progress in guava propagation has taken place in the last 100 years. It is important to know how to use the same methods of graftings and cutting. Detection of growth regulators, information on role of the juvenile stage in reproduction, advances in knowledge of chimeras, micro-propagation and application of vegetative propagation to prevent diseases caused by viruses and other pathogens. One can propagate guava by buddings, air layering, stoolings and inarching are not yet commercially feasible due to different success rates, the lack of a tap root system and burdensome processes. The purpose of this review is to discuss the diverse methods of propagating guava which are used commercially and the advancement made in recently.

1. Introduction
Green chemistry represents a transformative approach to chemical research and industrial practice, emphasizing the design of products and processes that minimize environmental impact and enhance sustainability. Introduced by Paul Anastas and John Warner in 1998, the field is grounded in the Twelve Principles of Green Chemistry, which provide a framework for reducing waste, improving energy efficiency, and minimizing the use of hazardous substances. These principles guide chemists in creating safer, more sustainable processes across various industries (Dichiarante et al., 2010).
1.1. Green Chemistry Defined
At its core, green chemistry seeks to reduce or eliminate the generation of hazardous substances in the design, manufacture, and application of chemical products. Unlike traditional environmental protection strategies, which often focus on managing waste and emissions after they have been created, green chemistry aims to prevent pollution at the source. This preventive approach is not only environmentally beneficial but also economically advantageous, as it can lead to cost savings through more efficient use of resources (Basics of Green Chemistry, 2013).
1.2. The Twelve Principles of Green Chemistry
The Twelve Principles, which include waste prevention, atom economy, the use of safer solvents, and the design for energy efficiency, serve as the foundation for green chemistry practices. These principles encourage chemists to rethink traditional methods and to innovate in ways that reduce the environmental footprint of chemical processes. For example, the principle of atom economy focuses on designing reactions that incorporate all reactants into the final product, minimizing waste and maximizing efficiency (12 Principles of Green Chemistry, 2021).

Abstract

Sabatayn basin is one of the two mature basins producing oil and gas in Yemen. Due to the recent decline in oil production, the exploration activities have been extensively concentrated mainly on these two basins (Sabatayn and Sayun-Masilah). So, this present study has been conducted to evaluate the exploration potential of the remaining trap areas within these mature basins. Fractured basement of reservoir becomes very attractive exploration target in Yemen recently, after the recent discoveries of basement fractured oil fields. As the evaluation of basement traps needs time and fund, to reduce the same, this research study uses a new technique which was devised with the help of Geoinformatics by analyzing the surface and subsurface lineaments effectively. In this study, a satellite image Enhanced Thematic Mapper (ETM+7) based analysis was conducted for extracting surface lineaments, and for the subsurface lineaments, the basement lineaments were extracted from seismic, magnetic and gravity data. An orientation analysis of these surface and subsurface linear features was performed to detect the basic structural grains of the study area. The correlation between these structural grains and subsurface oil and gas traps was performed to understand the connectivity to the reservoirs. This paper discusses in detail about the same and the importance of using surface and subsurface lineament analysis for delineating hydrocarbon reservoirs in the study area.

Semen collection is the most important component of any frozen semen production programme as a high quality end product is not possible unless the raw material is of excellent quality. Therefore, all care should be taken to collect semen aseptically with the aim to harvest the best quality neat semen for processing. The person collecting semen should understand bull’s behaviour and should be friendly with him. Professional bull management results in increasing sperm output and enhancing productive life of the bulls. One must know potentials and limitations of the reproductive capacity of bulls. A highly professional and dedicated team of bull handlers and semen collectors is required for this purpose. The persons involved in bull management should be familiar with bull’s sexual behavior and male reproductive physiology. Preferably a veterinarian should collect semen.

The UN designation of 2013 as the International Year of Water Cooperation aptly demonstrates growing gap between water supply and demand. These symptoms, which are already visible in a few regions around India, are soon to assume a national proportion and may become permanent feature of the water sector in the country, unless suitable policies are adopted quickly to manage water demand and supply at different levels. Water demand is growing fast due to a rapid population growth and economic activity, but water supply is not growing at the same rate because of serious ûnancial and physical limits for supply augmentation. Water resources developed at present amount to about 680 km³, which constitutes 61% of the utilizable potential of 1122 km³. However, it is difficult to add supply beyond this level due to heavy costs, environmental concerns and interstate water conûicts. In contrast, the total demand for water is projected to reach 784–843 km3 by 2025 and 973–1180 km³ by 2050 (Ministry of Water Resources, 2000). Recent research studies predict that, if the demand– supply gap continues to increase, nine basins that have over four-ûfths of the total water use in India will face physical water scarcity by 2050 (see Amarasinghe et al., 2007). For a heavily populated, monsoon-dependent and rural-based country, such as India, water scarcity of this magnitude will not only lead to serious water conûicts among sectors and regions, but also have a devastating effect on the food and livelihood fronts.

5.1 INTRODUCTION

A GIS database without single error is reliable for decision making. There are various possible sources of errors in GIS. If an error is not removed during scanning, the final output will also have that error. Besides whatever the work has been carried on wrongly scanned map it will add to errors because the source map itself's erroneous. This is like garbage in garbage out proverb. If wrong data is taken for analysis it will only result in wrong output. Hence it is important to remove error at every stage of GIS work. It is important to locate the sources of errors so that due care may be taken while handling a project.

5.2 ORIGINAL SOURCES OF ERRORS

All the equipments which give attributed data and spatial data will give errors. Before going to field or before collecting data all the related instruments should be calibrated properly. Also the instrument should not cross the permissible error. Besides these while using data from diversified sources errors pertaining to those instruments are mixed to give a different result. When very good accuracy is desired data should be collected from high end equipments. Even if one adds the data from a comparbly less accurate instrument to the data of many accurate instrument is then the result obtained finally will not reliable enough. Global Positioning System (GPS) is available with mm accuracy to meters accuracy. Also surveying with suitable map projection and datum is important; otherwise the result will be wrong. Survey instruments posses some inaccuracy and when a person is using it he should have the accuracy over the instrumental like rain gauge, water level recorders which give attributed data which should be checked for instrumental inaccuracies and method of data collection before using it. Likewise satellite and aerial sensors miss some data and some error are inherent. Such errors should be removed before moving ahead. Errors are resulted due to map reduction, enlargement, data editing and computation method adopted. At the same mapping instruments also possess inaccuracies. When after certain interval a person is going for survey, the registered object may have been changed. Many new features might have come up. Hence the established control points are changed and if the wrongly placed control points are taken for survey then the result itself will be wrong. If proper resolution is not available in the instruments, then the instruments may not capture the minute details which are required.
