ABSTRACT

The totipotency of triploid endosperm tissue is exploited in many vegetatively propagated crops. Hevea brasiliensis, the most important commercial source of natural rubber, is a highly heterozygous perennial tree with a long breeding cycle. Conventional method of triploid production by crossing a diploid with an artificially induced tetraploid is a lengthy and laborious process. Hence in vitro regeneration of plants from endosperm tissue provides an easy and direct approach for the production of large number of triploids. Hevea fruits at different developmental stages were collected and sterilized using 0.1% HgCl₂ for 15 minutes. Seeds were dissected out and the embryos and inner integuments were removed. Endosperm is cut into small pieces and cultured over MS medium supplemented with various levels of sucrose, phytagel and growth regulators viz BA, Kin thidiazuron, 2,4-D, IBA, NAA, zeatin & GA. Organic supplements viz. yeast extract, casein hydrolysate, coconut milk and banana powder were used for callus and embryo induction. Optimum callus induction was obtained in media supplemented with 2,4-D (2.0 mg ^-1) and Kinetin (3.0 mg^-1). On further subculture of the primary calli to medium containing zeatin (1.0 mg ^-1), embryogenic calli could be obtained. Embryos were induced in MS medium supplemented with ABA (0.3 mg ^-1) , Kin (0.3 mg ^-1) and GA (0.5 mg ^-1). Maturation, germination and bipolar differentiation of the embryos were achieved in MS medium devoid of growth regulators. Root tips from the germinating embryos were subjected to cytological analysis and found to be triploids (3n=54). Regeneration from Hevea endosperm is being reported for the first time. The results indicates that like many other crops, Hevea endosperm responds well under in vitro conditions and endosperm culture could be utilized as a viable technique for triploid plant production.

Endotracheal intubation is the placement of a tube in the trachea to provide a patent airway.

It is a valuable technique that enables to attach an animal to a breathing circuit or, just as importantly, to secure an airway during an emergency such as respiratory or cardiac arrest.

It is important that time be taken to learn the anatomy of the laryngeal area and the skill of intubation so that intubation may be performed quickly and with little chance of misplacement.

Abstract

In its natural environment, a plant faces various types of stressors. In fact, stress in moderation is a welcome event in plants. Only when it is in excess, would it compromise the productivity of plants. Beyond a threshold, stress (biotic and abiotic) has a detrimental effect on plant growth causing extensive yield losses in crop plants worldwide. Plants being sessile, have evolved a complex set of mechanisms to perceive the changes in the environment. Plants respond to minimize the potential damage due to stress while simultaneously preserving resources vital for their growth and development. The chapter presents an overview of various types of biotic and abiotic factors that act as plant stressors and the mechanisms by which plants respond to these stresses. The chapter concludes with a perspective on how the plant’s innate stress response machinery can be exploited for achieving higher tolerance to stress in crop plants.

Over the period of time, the dairy sector has added distinct significance to growing Indian economy. India contributes nearly 19.54% to the global annual milk production with an impressive upliftment of 3.6% in yearly production rate as per the latest available data from FAO International.

1. Introduction

Energy balance means keeping an account of how the flow of energy is taking place in and out of any system or process. It helps the engineers to estimate the total energy requirement and identify the area for conservation of energy in any process. In food processing the concept of energy balance is applicable in unit operation such as blanching, drying, evaporation, freezing, refrigeration, distillation, crystallization. The scopes of energy balance in food industry are:

i) Streamlining and reduction of energy consumption in the existing process.

ii) Selection and sizing of any equipment and process.

iii) Economic analysis of alternate process/technology.

iv) Designing new economically viable process/technology

Introduction

Over the years, processed food industry has become the largest growing industry in the world. The convenience food industry with the state of the art technology has been proved very successful in reaching every household and have started replacing fresh and healthy foods with the processed ones (Srinivasan and Shende, 2016).

Demand for processed and convenience foods are constantly on rise and convenience food segment is rising by leaps and bounds. Changing life style, food habits, displacement of rural population to urban centres, insufficient time to prepare healthy food and changing socio economic needs have led to the industrialization of the food supply and resulted in the development of convenience foods and today a great variety of the same are available for sale to the consumer throughout the world (Tillotson, 2003).

These convenience foods are available readily, convenient, inexpensive with pleasing organoleptic quality, requires minimal or no preparation before consumption. Varieties of convenience foods which are available in the market play a prominent role in the food choice of today’s consumer, and they include frozen and canned vegetables, bakery products, soups, sauces, prepared meat and fish, chilled and frozen dairy products as well as ready to eat and shelf stable products (Tillotson, 2003).

Rapid switchover of the consumer from the traditional dining practices to fast food centres, generally feed on quick and easily made products called fast foods, often termed as unhealthy junk foods. These foods are rich in saturated fatty acids, several refined components, high carbohydrates etc., which ultimately lead to the negative impact on physical and mental health of the consumer, contributing to several chronic diseases such as cardiovascular complications, cancer, atherosclerosis, liver disease, type 11 diabetes (Veggie et al., 2018) etc.

Therefore, focussing much about the health of the consumer, there is a great need for a healthy and a balanced diet to meet the basic needs of the human body (Mendes et al 2013) with an appealing organoleptic properties and appearance.

Introduction

The basic needs of life are food, clothing and shelter. In the 21^st century a fourth need added to mankind is energy. According to the laws of physics, energy is defined as capacity to do work. Energy, economics and the environment are mutually dependent. Also, there is very close relationship between agriculture and energy. The level and pattern of energy use in agricultural production system depends on variety of agronomic and socio-economic factors. Energy use in agriculture encouraged maximization of yields from limited available arable land, minimization of labour intensive operations and improving standard of living. Efficient and effective energy use in agriculture is one of the conditions for sustainable agricultural production, since it provides financial savings.

Abstract

Design, operation and optimization of dryers demands the calculation of energy consumption, in most cases in the form of thermal energy, equipment sizing, temperature and moisture distribution of solids as well as temperature and humidity distribution of drying air. Energy calculations are very important as drying is a widespread process in a variety of industries and is highly energy demanding. In the energy analysis of the process the first step is the estimation of the minimum energy requirement followed by the estimation of energy rejection through solids stream and especially through drying air. Increase of thermal efficiency is always willing and the two most common ways for its achievement is the application of heat exchange between cold feeding air and relatively hot rejecting drying air and hot air recirculation. The later is also employed for the adjustment of air temperature and humidity gradient through the dryer. The combination of a heat pump with the dryer decreases considerably the thermal energy consumption but demands electricity and the method can be beneficial in cases of excess electricity production in the process plant, e.g. by cogeneration. Utilization of exhaust hot air from the main drying unit for the predrying of wet solids can also decrease the total energy requirement. The application of humidity adsorption from the feed air increases its drying potential, but regeneration of adsorbent is required. Grand composite curve of the process plant can reveal potential heat sources from different unit operations.

7.1. What is Energy Conservation?

In order to protect resources for future use and to lessen environmental degradation, energy conservation refers to actions performed to limit energy use.

.2. What is Energy Efficiency?

The definition of energy efficiency is the use of less energy to carry out a task or achieve a goal. Homes, buildings, and manufacturing facilities that use less energy to manufacture things require less energy to heat, cool, and operate appliances and electronics.

13.1 Introduction

At a national level, the agricultural sector is one of the major potential users of energy in the Indian context. Further, it is often highly dependent on the supply of electricity and fuel in order to function properly. The term “agriculture” refers to all on-farm activities required for farming, raising animals, and associated activities associated with farmers, growers, and entrepreneurs. Fuels such as petroleum and electricity are primarily used for the operation of pump sets and other operations. In the future, this may result in problems with supply and price. Moreover, India has relatively small reserves of crude oil and will eventually be forced to import more crude oil to make up for the lack of reserves. In order to save energy and money on the farm, farmers must identify opportunities for energy conservation on the farm in order to maximize energy efficiency. 

Introduction

Energy Consumption is considered as the energy used to do any task in any kind of a simple domestic building to a complicated manufacturing industry. For instance, in a household, energy is consumed in the form of electricity used to run an Air Conditioner to make a room cool, gas used to cook a dish etc. In a car industry, energy is consumed in the form of electricity to manufacture a car part. In the transport sector, petrol or diesel or gasoline is used as a run a car or bike or other vehicles.

2.1 Time and Energy Requirements of Work
The time and energy requirements of work can vary significantly depending on several factors related to the nature of the work, the worker’s capabilities and motivation, and the workplace environment. Let’s explore each aspect:
1. Nature of the Work
Complexity: work that requires high levels of skill, expertise, and problemsolving will generally demand more time and energy.
Physical demands: jobs that involve manual labor or physically strenuous activities can be more energy-intensive.
Cognitive demands: intellectual or creative work can be mentally taxing, requiring concentration and focus for extended periods.
2. Worker Factors
Physical health: a worker’s overall health and fitness level can impact how much time and energy they can dedicate to their job.
Skill set and experience: experienced workers might complete tasks more efficiently, reducing time requirements.
Motivation: highly motivated individuals tend to invest more energy and time into their work.
Work-life balance: if a worker is dealing with excessive stress or personal issues, it can affect their ability to concentration and perform optimally.
3. Workplace Factors
Work environment: a comfortable, well-designed workspace can contribute to increased productivity and reduced fatigue.
Technology and tools: access to advanced tools and technology can streamline tasks and save time and energy.
Support and collaboration: a positive work culture and supportive colleagues can enhance job satisfaction and productivity.
Workload and deadlines: unrealistic workloads and tight deadlines can lead to stress and exhaustion.

The rapid growth of Large Language Models has produced remarkable advances in artificial intelligence but has also increased computational requirements, energy consumption and environmental impact. This chapter examines the relationship between large-scale AI development, energy efficiency and sustainable computing. Modern AI models may contain billions or even trillions of parameters and require extensive datasets, powerful accelerators and energy-intensive data-centre infrastructure for training and inference. The chapter investigates the environmental consequences associated with model development, including energy consumption, carbon emissions, cooling requirements and resource utilization. It examines model-level optimization techniques such as pruning, quantization and knowledge distillation as methods for reducing computational demands. System-level approaches, including specialized hardware accelerators, energy-efficient data centres, improved cooling systems, renewable energy and intelligent workload scheduling, are also considered. The distinction between energy efficiency and broader sustainability is emphasized, with attention to metrics such as energy per inference, total energy consumption, carbon emissions and hardware lifecycle impacts. The chapter further highlights the importance of transparent sustainability reporting, green computing and governance policies. Sustainable AI development requires balancing model performance and innovation with responsible resource use and long-term environmental objectives

5.1. Introduction

The energy equivalent can be considered to be an alternate energy unit, precisely related to units such as the joule, calorie, or Btu. In energy talks, many units are employed. They are divided into two categories: (a) basic units and (b) source-based units.

Introduction
The study of energy flow through the ecosystem is known as Ecological Energetic. Ecological Energetic is the scientific discipline that investigates the movement ofenergy within an ecosystem. The process of energy transfer that takes place within a food chain is referred to as energy flow. The functioning of all species in an ecosystem is dependent on the energy they derive from the energy flow. The ecosystemsustains itself and achieves stability through the process of energy transfer.
Energy Transfer/Flow
Solar energy is the primary source of energy that enters the food chain at the level ofproducers, which are plants. Through the process of  photosynthesis, plants utilize solar energy to transform it into chemical energy, which is then used to produce various components of plants such as leaves, flowers, fruit, branches, trunks, and roots. Plants are referred to as producers in the ecosystem because they have the ability to transformthe sun’s energy directly into their tissues, allowing them to thrive. Herbivores consume the plants as nourishment, so obtaining energy. A significant portion of this energy is expended on the metabolic processes of these organisms, including respiration, digestion, tissue growth, blood circulation, and body temperature regulation. Energy is also expended in activities such as foraging, seeking refuge,reproducing, and nurturing offspring. The predators rely on the herbivores as their source of food.

6.1 Introduction

Energy planning is possible only with knowledge of past and present energy consumption and future energy demand. There are number of factor which affects the energy consumption pattern significantly. These include energy prices, availability, reliability of supply, uniformity of quality, convenience in use, technical and economic characteristics of energy using equipment & appliances, population growth, income rate of urbanization, educational status, social acceptance, social habit, present knowledge of beneficiary etc.

The energy planning differ in planning sectral wise and planning sources wise. For sector planning purposes, estimates are needed of the short and long run price elasticity for every specific energy resource. Where as in planning sources wise, one must consider its long term availability & its costs.

In general, to cope up future risk and uncertainty, we need to predict the future event. The likely future event has to be given from and content in terms of projected course of variables i.e. the forecasting. Projection is of two types – forward & backward. It is the forward projection of data variable, which is named as forecasting.

10.1 General

The term “biomass” generally refers to renewable organic matter generated by plants through photosynthesis. Materials having organic combustible matter is also referred under biomass.

Biomass is an important fuel source in our overall energy scenario. Biomass is produced through chemical storage of solar energy in plants and other organic matter as a result of photosynthesis. During this process conversion of solar energy in sugar and starch, which are energy rich compounds takes place. The chemical reaction of photosynthesis can be written as:

Our animal companions are our family members. We want the best for them and want them to be healthy and happy. However, just as it is with everyone else, our companion animals can also fall ill and suffer from emotions such as grief, fear, and anxiety. And while we follow all expert medical advice, sometimes we may wish for something more – something that will make life easier for them as well as us. This is where the concept of energy healing for animals comes in – to comfort and support our animal companions. With joy, we watch them relax with a sigh; we see our nervous dogs calm down, and those recovering from an acute illness get back on their paws in no time. Energy healing for animals involves a holistic approach to ensure the physical, emotional, and spiritual well-being of our animal friends. It is based on the fundamental concept that just like us, our animal companions too have a subtle energy layer, and they too have vital life-force energies or Prana or Qi. And just like us, they, too, have chakras and meridians through which the Qi flows. Energy healing is a set of powerful techniques practiced to calm and restore the balance of the body. This system is largely based on the removal of energetic blocks and helps restore the body’s energy levels. It is crucial for those living with companion animals to understand the importance of energy healing for their animal companions, as it encompasses a broad range of alternative and complementary therapies designed to support the natural healing process of animals. Here are some proven, popular, non-invasive energy healing techniques that bring relief and comfort to companion animals.
1. Animal Reiki: The word Reiki means “mystical energy.” The system of Reiki for healing was revealed by Japanese Buddhist practitioner Mikao Usui in the early 1900s. And while it was initially meant for humans, practitioners soon discovered that animals responded much more swiftly and effectively to this gentle, non-invasive energy work.
2. EFT Tapping: This involves tapping on specific points on the body to free up emotional blocks. EFT Tapping for animals brings powerful transformations when an animal is struggling with emotional distress, such as grief over the loss of a loved human or animal.
3. Scalar Wave Healing: Scalar Wave was discovered in the 1900s by James Maxwell and later Nicolas Tesla. Scalar Wave harnesses the healing power of high vibrational frequencies meeting to create a standing wave, and practitioners use this to bring about healing at a cellular level.
4. Shamanic Healing: In this ancient technique, practitioners work with the elements of nature, such as plants, trees, and stones, as well as beings in other dimensions, to bring about healing. Shamanic healing can reach beyond space and time and has been very effective in releasing old trauma or emotions that are often hidden beneath layers of survival mechanisms.
5. Healing Mantra: Ayurveda, the Indian system of medicine, advocates about different types of Chikitsa. Daivavyapashraya Chikitsa is one of the treatment approaches concerned with Spiritual way of treatment. It includes so many approaches, amongst all Mantra Chikitsa is described in Ayurveda at various places as a potent approach. It is discussed for both the healthy and unhealthy conditions. Mantra comes from Sanskrit word which means sacred message or text, spell. The word Mantra is derived from Man+Tra, man—mananaat---just by chanting and tra—trayate---- we can protect ourselves. Means, just by chanting one can save himself in the universe. i.e. it is saved from onset of disturbances. Mantras are the words loaded with power and sounds capable of penetrating our body into deep levels. Mantra chikitsa is the ancient science originated from Vedas, this is a parallel science to Ayurveda also called alternative medicine system.Mantra Chikitsa is one among the Daivavyapashraya Chikitsa highlights the importance of concept of Mantra. In Atharva Veda and Kaushikasutra, the two most ancient and authentic sources of Daivavyapashraya. Mantra Chikitsa is mainly used for both preventive and curative aspect. It is also used for the enhancement of the Gunas of Aushadhi. Effect of Mantra is described as Prabhavajanya action. Prabhava means the specific and characteristic action of substances, it is called as Acintya. Mantra Chikitsa cure the Karmaja Vyadhi and Agantuja Vyadhi. In the Vedic period, Daivavyapashraya Chikitsa was followed in various rituals.
