The IPPC Secretariat provides support for the International Plant Protection Convention (IPPC) and coordinates the annual work programme put in place by the Interim Commission on Phytosanitary Measures. The three key activities of the Secretariat are: standard setting, technical assistance and information exchange. To facilitate the information exchange obligations laid out in the IPPC, the Secretariat adapted an existing Web-based environment to allow users to be able to both deposit and retrieve data from various sources. This Web site was named the “International Phytosanitary Portal” (IPP). As the IPP continues to evolve every effort are being made to ensure that specific issues necessary for the management of invasive alien species are addressed.

This chapter describes various multivariate techniques which are useful in animal breeding. The genetic correlation with multiple response variables is already explained in the chapters on Correlation and Genetic Parameters. The other techniques including MANOVA, Principal Component Analysis, Factor Analysis, Cluster Analysis and Discriminant Analysis are explained.

Multivariate analysis is referred to a set of data with multiple response variables in general and such data is encountered often in animal breeding analysis. The simplest form of multivariate analysis is the genetic correlation where two or more traits are analysed together as response variables with factors affecting them on the right-hand side (RHS) and details of these are already explained in earlier chapters.

1. Introduction Millets have gained popularity as staple foods worldwide, particularly in regions with hot and humid climates. These crops are often cultivated in marginal areas where major grains struggle to yield significant harvests (Thapliyal and Singh, 2015). One such millet is finger millet (Eleusine coracana), native to Ethiopia, and widely grown in Africa and India, where it is known by various names, including ragi and mandua (Table 1). In many developing countries, finger millet serves as a staple for a substantial portion of the population, especially those belonging to lower economic strata, providing essential nutrients (Chandra et al., 2016).

Hydroponics is a technique of growing plants using mineral nutrient solutions with or without the use of an inert medium such as gravel, soil, vermiculite, rock wool, peat moss, saw dust, coir dust and coconut fibre-provide mechanical support. The term Hydroponics was derived from the Greek words ‘hydro’ means water and ‘ponos’ means labour and means water work. The word hydroponics was coined by Professor William Gericke in the early 1930s; describe the growing of plants with their roots suspended in water containing mineral nutrients. Researchers at Purdue University developed the nutriculture system in 1940. During 1960s and 70s, commercial hydroponics farms were developed in Arizona, Abu Dhabi, Belgium, California, Denmark, German, Holland, Iran, Italy, Japan, Russian Federation and other countries.

Summary

The huge accumulation of agro-industrial waste-materials generated by the milling, brewing and various agriculture and food based industries which in total amount to be about 500 million tones per year in India. Most of these by-products contain three major structural polymers such as cellulose, hemicellulose and lignin. These are also the main source of feed for domestic animals. A high proportion of this waste material is carbohydrate and phenolic compounds. Accumulation of this kind of biomass not only results in the deterioration of the environment, but also loss of potentially important materials. Biological degradation, now-a-days, has become an increasingly popular alternative for the treatment of agricultural, industrial, organic as well as toxic wastes. Cellulose and hemicellulose being the major constituents of these materials can be referred to as valuable resources for a number of reasons, mainly due to the fact that they can be bio-converted easily into valuable products. These wastes can be processed to yield a number of value added products, such as biofuels like biohydrogen, bioethanol along with a variety of chemicals. Various treatment methods such as physical, chemical, biological are employed for the production of value-added compounds. Various phenolics like ferulic acid and vanillin are world’s most prized flavor compound mostly obtained through microbial treatment of agro-wastes.

Introduction

Climate resilience is the capacity of a system, community, or person to foresee, prepare for, react to, and recover from the consequences of climate change while simultaneously preserving critical functions and minimising long-term harm. This ability is described as the ability to adapt to climate change. In order to handle the issues that are brought about by a changing climate, which include increasing temperatures, severe weather events, rising sea levels, and altering weather patterns, it is necessary to take a proactive approach.

Introduction

Ornamental plants, prized for their aesthetic appeal and vital role in horticulture and landscaping, enhance both private and public spaces with their beauty, contributing significantly to mental well-being and environmental health. These plants, encompassing a diverse array of species and varieties are cultivated not just for their visual splendour but also for their aromatic, structural and ecological benefits. The successful cultivation and maintenance of ornamental plants however require meticulous care and expertise, especially in managing their growth and development. This is where plant growth regulators (PGRs) become indispensable tools in ornamental horticulture Plant growth regulators (PGRs) are a class of naturally occurring and synthetic compounds that play a crucial role in the regulation of plant growth and development. These substances, even when applied in minute concentrations, can have profound effects on various physiological processes within plants, including cell division, elongation, differentiation, flowering, fruiting and senescence. The primary categories of PGRs include auxins, cytokinins, gibberellins, ethylene and abscisic acid, each contributing uniquely to plant development and stress responses. Auxins, such as indole-3-acetic acid (IAA), are pivotal in cell elongation, apical dominance and root initiation, making them indispensable in rooting cuttings and maintaining plant structure. Cytokinins, including kinetin and benzyladenine, promote cell division and shoot formation, thus enhancing branching and delaying leaf senescence.

Bulb crops include onion, garlic, leek, shallot, welsh onion and chive all belonging to the genus Allium.  This genus was earlier included in the family Liliaceae due to its superior ovary.  It was later shifted to Amaryllidaceae as flowers are born in a bracted umbel on top of a scape.  Being the typical genus in the family Amaryllidaceae, a new separate family status was given to all the specious under Allium as Alliaceae.

Preserving plant materials in a dried form is not a new idea. It has been considered as an art for hundreds of years. Fragrant dried herbs were placed in Egyptian pyramids. Dry flower arrangements have been popular in Europe for several centuries. During 1700 A.D, the early American settlers used dry flowers to brighten their homes. Any plant material can be preserved for use as dry flowers (Al Pertuit, 2004). Though enormous work is being done in this field, most of the literature is published by horticulture amateurs. Scientific work in this area is less. However, a review of the research work done in dry flower technology is discussed in detail.

1.1 Introduction

The word ‘computer’comes from the word ‘compute’, which means to calculate or perform a sequence of operations. Hence, a computer is normally considered to be a calculating device, which can perform arithmetic operations at enormous speed.

In other words, a computer takes information (or input), processes it according to a set of instructions (or process), and gives back a result (or output). In this respect, it is very similar to a calculator, but obviously somewhat more complex.

A computer is a multi-function platform. The same machine can perform many different tasks by using different programs. The programs (also termed as applications) are written to do everything imaginable. In other words, we can say that a program is a set of instructions issued to a computer in order to get the desired output.

Definition

A Computer can defined as an electronic device that takes input from its user, stores, processes data and generates the required output as per the processing instructions given to it by the user.

22.1 INTRODUCTION

The life-styles, economic conditions and food habits have a great effect on food marketing. There is an increasing demand for fresh fruits and vegetables and their processed products. Fruits and vegetables are processed into a variety of products and it is required to be picked at its right stage. For making juice, fruits should be picked at ripe and soft stage, for canning purpose it should be picked at fully mature but firm just before ripe stage. Fruits and vegetables are passed through a long channel before their consumption; which may lead to a number of undesirable changes in their composition. Thus effective post harvest management of fruits and vegetables is essential to provide their acceptable quantity and quality worth consumption. In this regard handling, processing and preservation and value additions form important loci.

Abstract

This research has analyzed the “Factors Affecting Shoes ‘Consumer Preference In Nekemte Town:-An Econometric Analysis” considering different age level, income level high grade completed, social status, and sex with an objectives of identifying determinants of preference of consumers between domestic goods and import close substitute goods. The study was under taken on the consumer goods that are produced in domestic industrial and imported from abroad because of international trade. The goods in this study are only shoes. The data is collected from 100 respondents with different age, income level, educational level and sex through both questionnaire and interview. More than half (51%) of respondents prefer to use locally substituted foreign products that were allowed to choose either foreign or domestic shoes. Proud of and conformity to one’s life styles have statistical significant positive association with preference of buying locally produced shoes. Youth especially youth females have strong attachment with foreign products. People considering the quality have preferred the current generation.

2.1 Introduction

Topographic expression is the replica of geological structures present within the earths surface. When various types of rocks of an area are displayed on a map (sheet of paper), it is known as Geological Map. Normally geological maps prepared on topographic maps. Surface topography is best presented by contour lines on a plain paper.

The importance of geological maps is to understand the nature of structure and distribution of surface outcrops with their relation to contour lines. Horizontal and dipping beds are easily identified on map because, horizontal beds runs parallel to contour lines while inclined beds cut through different contours. The angle and direction of dip can be calculated from geological maps. Geological maps are of great importance to civil engineers, after studying geological maps and consultation with geologists, civil engineers can advice for construction of engineering structures like excavation of road cuttings and construction of canal, bridges, dams and tunnels etc. Geologists get vital clues about the geological history of an area, and can draw a cross section of an area and know the structure present underground.

3.1. INTRODUCTION

In this chapter, we will study the measures of central tendency which is a numerical method to explain the data in brief. We can see examples of summarizing a large set of data in day to day life like average marks obtained by students of a class in a test, average rainfall in an area, average production in a factory, average income of persons living in a locality or working in a firm etc.

One of the most important objectives of statistical analysis is to get one single value that describes the characteristic of the entire mass of data. Such a value is called the central value or an ‘average’ or the expected value of the variable. This single value is the point of location around which individual values cluster and, therefore, called the measure of location. Since this single value has a tendency to be somewhere at the center and within the range of all values it is also known as the measure of central tendency. The purpose of computing an average value for a set of observations is to obtain a single value which is representative of all the items.

Agriculture has been the base of subsistence for human settlements on the planet earth. According to the Food and Agricultural Organization (FAO), people in the developing world where the population increase is very rapid, may face hunger if the global food production does not increase by 50–60%. Contribution from developing countries and developed countries to world production in 1975 was about 38% and 62%, respectively. If yield increase is keeping pace with increasing population, mass hunger can escape. In the preindependence period, Indian agriculture was usually described as a gamble with monsoons and their failures resulted in widespread famine and misery. In the last few decades, Indian agriculture has made a remarkable progress even with increased population and decreased per capita availability of agricultural land. World population is projected to be over 8 billion by 2025 and nearly 10.5 billion by the end of next century. To maintain the status quo, food production needs to be doubled. Estimates by the FAO and WHO (1992) and the Hunger Project (1991) suggest that around 1 billion people in the world have diets that are ‘too poor to abstain the energy required for healthy growth of children and minimal activity of adults’. The causes are complex and it is not entirely the fault of overall availability of food. Modern agriculture begins on the research farm, where researchers have access to all types of inputs for crops at all the appropriate times. But, even the best performing farms cannot match the yields of researchers. For high productivity, farmers need to have access to the whole package – improved seeds, water, labour, capital or credit, fertilizers, pesticides and other developed technology. Many poorer farming households simply cannot adopt the whole package. Very often delivery systems are unable to supply them on time.

2.1 Definition and Concept

An operating system (abbreviated as ‘OS’) is the program that, manages all the other programs in a computer. Every general-purpose computer must have an operating system. It provides support for the loading and execution of other programs which are known as Application Programs.

Introduction

Instead of using soil, the unique technique of hydroponics grows plants in a nutrient-rich water solution. Using a tightly controlled environment, gardeners may optimise factors including sunlight, pH balance, and nutrient levels to maximise plant development in this agricultural approach. Hydroponics allows plants to grow more quickly and produce more by delivering nutrients straight to their roots. Water efficiency, less soil-borne disease risk, and the capacity to grow crops in non-arable or urban areas are just a few of the benefits of this technology. More and more people are turning to hydroponics as a means to grow their own food in a more regulated and efficient manner, all while reducing their impact on the environment.

1.1 Introduction

Gender permeates every facet of society, influencing power dynamics, access to resources, and opportunities. Understanding gender requires not only defining its conceptual framework but also acknowledging how these concepts manifest in everyday life, often creating deep divisions. Gender divides whether in education, employment, health, or political participation are enduring realities that reflect the unequal distribution of opportunities and rights between men and women, as well as between those who identify beyond the binary. These divides are more than social phenomena; they have concrete economic, political, and developmental impacts. Recognizing the persistent gaps in access and outcomes between genders has led to the development of gender-sensitive policies, such as gender budgeting. Gender budgeting is a critical tool for addressing these divides by ensuring that public resources are allocated equitably to benefit all genders. By focusing on the differential impacts of policies and budgets on women, men, and gender minorities, governments and organizations can work toward creating more inclusive and fair societies.

This chapter will introduce key gender-related concepts that form the foundation for understanding how gender influences social, economic, and political life. It will explore the roots and ramifications of gender divides across various sectors and explain how gender budgeting is employed as a strategic approach to reduce these disparities. Through this exploration, we will highlight the importance of integrating gender perspectives into policy and resource distribution to foster equity and social justice.

1. Introduction

Climate change includes higher temperatures, changes in rainfall patterns, alterations in the frequency and distribution of weather events such as droughts, storms, floods, and heatwaves, sea-level rise, and the consequent impacts on human and natural systems (Riedy, 2018). Climate is the average weather in a given area over a longer time. A description of climate includes information on, for example, “the average temperature in different seasons, rainfall, and sunshine. Also, a description of the chance of experiencing extremes is often included. Climate change is any systematic change in the long-term statistics of climate variables such as temperature, precipitation, pressure, or wind sustained over several decades or longer. Climate change can be due to natural external forcings (changes in solar emission or changes in the Earth’s orbit, natural internal processes of the climate system), or it can be human-induced” (Buonocore, 2022).

INTRODUCTION

By the turn of the century, consumers have been more demanding, sophisticated and discretionary. They want much safer, higher quality, and more convenient to foods. The food processor need to get the best from their existing processing technology in addition to looking for newer ones. New and alternative food processing methods and/or novel combinations of existing methods are continually being investigated by the industry in pursuit of producing better quality foods more economically. Thermal processing is one of the most important food preservation techniques that was first introduced at the beginning of 1800 and has evolved itself in to one of the most scientific mature food processing techniques of recent times. Both science and technology have gone through tremendous transformation in the last two centuries and today it is the most reliable method to assure food safety and stability. Developments in thermal processing and evolution of non-thermal processing technologies like high pressure processing, pulsed electric field, pulsed light etc. have enhanced the utility of thermal processing principles and increased the awareness of possible alternative processing technologies.
