Principle

The use of boric acid as an ammonia absorbent was first introduced by winkle  (1913-15). Conway and O’Malley (1942) used boric acid for ammonia absorption in their original micro diffusion technique.

The ammonia liberated in the outer chamber by alkali addition in the usual way is absorbed in boric acid mixture plus indicator in the central chamber (slightly reddish), the pH of this mixture being approximately 5 before absorption. During the ammonia absorption the pH of the mixture rises, and to upwards of 8.0 (the strength of the mixture being such as to prevent it rising further). After the required period, the fluid in the central chamber is titrated to a faint permanent reddish tint with standard acid. A mixture of methyl red and bromocresol green was found satisfactory  to work as an indicator to assist in titration job.

ABSTRACT

The improper disposal of food waste poses an environmental threat. The management of food waste in a sustainable way is always a challenge. Food waste is generated at various stages starting from food production till consumption. The cooked food waste generated due to various reasons leads not only to a loss of the food produced but also the water and energy used to cook it. This cooked food leftover can be served to the needy people or if not possible, can be processed further. This chapter focuses on various technological options for the management of cooked food waste in a sustainable way.

INTRODUCTION
In an internal combustion engine, fuel is combusted within the cylinder to generate power. During the power stroke, the temperature can reach up to 1600 ºC, which exceeds the melting point of engine components. The optimal operating temperature for internal combustion engines ranges between 140 ºF and 200 ºF, making cooling a crucial aspect of engine operation. It is estimated that approximately 40% of the total heat generated is released into the atmosphere through the exhaust, 30% is dissipated through the cooling system, and the remaining 30% is used to produce power.
The cooling system in internal combustion engines plays a vital role in ensuring the engine operates efficiently and reliably. It is responsible for maintaining the engine’s temperature within the optimal range, preventing overheating that can lead to engine damage. The engine generates substantial amounts of heat during combustion, and without proper cooling, these temperatures can rise to levels that exceed the melting point of engine components. This can result in engine failure, reduced performance, and significantly shortened engine life. The primary function of the cooling system is to absorb excess heat from the engine and dissipate it into the atmosphere, keeping the engine temperature within safe limits. This allows the engine to perform at its best while avoiding costly repairs and downtime.
The cooling system works by circulating coolant through the engine block, where it absorbs heat, and then transferring this heat to the radiator, where it is cooled by airflow or a fan. There are various types of cooling systems, including air-cooled and liquid-cooled systems, each offering distinct advantages depending on the engine’s design and application. Liquid cooling systems, which are more

Cooling systems play a vital role in cold chain logistics, serving as essential components that regulate temperature for storage, processing, and transportation. An efficient cooling system ensures that food and other perishable products remain fresh for extended periods, even before they begin their journey. Various cold chain products require specific temperature settings to maintain their quality and integrity until they reach their final destination.
For instance, tropical fruits such as bananas and pineapples must be stored at a consistent temperature between 12°C and 14°C. If the temperature exceeds this range, the fruits may ripen prematurely, compromising their quality. Likewise, food items like milk, vegetables, and other perishable fruits should be cooled within the range of 2°C to 4°C. This temperature effectively eliminates harmful pathogens and prevents bacterial growth, preserving the freshness of the produce.
For businesses dealing with frozen food, seafood, or ice cream, a more advanced cooling system is necessary—one that can maintain temperatures as low as -30°C. Such systems are essential to prevent thawing and spoilage, ensuring that frozen goods remain in optimal condition throughout their transportation and storage.

Coordinate Reference System (CRS) is a framework of coordinate based local, regional or global reference system used to represent the locations of geographic features. Coordinate Reference Systems (CRS) provide a standardized way to define the real-world geographic locations which further enable us to use common locations of geographic datasets for integration. The datasets from different sources and CRS are transformed to a common CRS in order to perform various integrated analytical operations like overlaying of data layers. Coordinate Reference Systems are mainly of two types:

1. Geographic Coordinate System: This is global or spherical coordinate system in which locations of features on earth are defined in terms of latitude and longitude values. Latitude and longitude are angles based on a point at the centre of the earth. In this system, locations are defined by degrees, therefore, distances cannot be measured accurately. The most common geographic coordinate system is the World Geodetic System 84 (WGS84).
2. Projected Coordinate System: In this system, locations of features are defined using cartesian x, y coordinates on a flat, two – dimensional surface. This system is based on sphere or ellipsoid projected on flat surface. Projected Coordinate System are generally referred as projec- tion. It is required for preparing maps on paper or computer screen. Un- like Geographic Coordinate System, projected coordinate system has ac- curate measurements of distance, angles and areas across the two dimen- sions. However, there is alwaystrade-offs between area, direction, shape, and distance in this system due to distortions created while representing ellipsoid or spheroid on a flat map. So, the projection type is selected based on its application. Most common projections are Universal Trans- verse Mercator (UTM), Lambert Conformal Conic and Albers Equal Area.

In the semi-arid tropics, where small farmers depend heavily on rain-fed agricultural systems, variability in precipitation has a dramatic impact on crop production and livelihoods. Because small-scale agriculture depends on rain-fed cultivation, it is vulnerable to factors such as flooding and drought. Unfortunately, the frequency of unexpected heavy rainfall or flood events has increased in many areas of Africa, including Southern Zambia. About 75% of farmers in Zambia engage in small-scale farming, with an average farm size of 2 ha (VAM Steering Committee Zambia, 1998). Most of these farmers cultivate maize, which is a staple food in Zambia, and stable maize production and increased productivity are important both for food security and to provide a livelihood to farmers.

In spite of its importance, little has been done to assess interactions of climatic variability with productivity performance of different livestock species, sustainability of livestock production systems, livestock based livelihoods and application of science of climate change on small holder and subsistence livelihoods. The climate and its change affect all productive traits and physiological functions of farm livestock and related livelihoods. Heat stress is the most detrimental constraint to livestock production, particularly in mountainous regions. Introduction and selection for highly productive animals and breeds has increased their susceptibility to adverse impacts of climate change. It is necessary to incorporate resilience through selection and breeding for thermo-tolerance and development of adaptable breeds. Modifications in shelter designs and management of production facilities will also be helpful in mitigating adverse climate impacts on animal production and health. Modern animal husbandry practices that target increased per animal productivity allow efficient utilization of feed nutrients and increase returns from fewer animals. Livestock need to be looked for their immense contribution to nutritional security and livelihoods. A well designed livestock production system is among the best ways for sustaining and improving livelihoods and this chapter details the possible options.

Introduction to Copyright Law
Copyright law is a fundamental mechanism for safeguarding intellectual property (IP). It provides creators exclusive rights to their work and controls its reproduction, distribution, and use. As creative industries expand globally, copyright law has become integral to protecting creators’ rights and enabling innovation. Originally stemming from the need to protect books, copyright now covers diverse mediums, including music, films, software, and digital content.
The Copyright Act is legislation that formalizes these protections and establishes rules regarding ownership, rights, duration, and infringement of copyrighted materials. Each country may have its own version of the Copyright Act, yet the overarching principles are largely similar due to international agreements such as the Berne Convention for the Protection of Literary and Artistic Works and the World Intellectual Property Organization (WIPO) Copyright Treaty.
Historical Development and Global Influence
The foundation of copyright law can be traced to early European statutes. The Statute of Anne (1710) in Britain is often considered the first formal copyright legislation, setting a precedent for other jurisdictions. The Statute of Anne aimed to promote learning by granting authors the right to control and profit from their work, forming the concept of authorial rights.
In the 19th and 20th centuries, as cross-border trade expanded, nations recognized the need for standardized copyright protection. The Berne Convention for the Protection of Literary and Artistic Works (1886) marked a pivotal moment, providing a framework for copyright on an international scale. The Universal Copyright Convention (UCC) (1952) and Trade-Related Aspects of Intellectual Property Rights (TRIPS) agreement further unified copyright standards, ensuring fair treatment of copyrighted works across borders.

Abstract

Intellectual property right (IPR) is the most serious, new branch of law and a legal right conferred by federal government in accordance with International conventions and treaties. IPR protects some of the finer manifestations of human achievement. IPR safeguards the application of ideas and information that are of commercial value. The exploitable ideas become more sophisticated and hope for a successful economic future depends increasingly upon the superior corpus of new knowledge and fashionable conceits.  Copyright law is one of the effective tools of IPR. Copyright law provides an incentive to creative activity of author and permits the society to benefit from those inventions. However, the technological advancement has made violation of copyright very easy and regulation very difficult. This paper aims at familiarizing  copyright laws and the powers enshrined in copyright laws.

I. INTRODUCTION

The Websites are soaked in information, much of it with varying degrees of copyright protection. In fact, the reality is that almost everything on the Net is protected by copyright law. E-business Websites are a composition of materials, often consisting of words, graphics, audio, and video that are expressed to the consumer as information content. The owners and Website developers carefully select the content to sell the company’s product or service. The subject matter expressed in the site is an electronic publication of this content. Since, designing, producing, and maintaining a sophisticated Website is very expensive, protecting content ownership is extremely important. Electronic commerce will continue to be highly competitive. As Websites become more and more interactive with consumers, their creation, design, and maintenance place enormous demands on innovative marketing techniques that should be legally protected.

Never before has it been so easy to violate a copyright owner’s exclusive right to copy the material. Everyone with a computer and an Internet connection creates his own Web pages and thus become a publisher. Hence the rules that once applied to only a few companies bind million of people now. Imagine having paid a Website developer hundreds of thousands of rupees to launch a killer application and acquiring millions of Rupees from a venture capitalist firm, only to discover that another e—business is using your online material. Or consider a scenario where your Website is linked to an e-business that displayed copyrighted material without the owner’s consent. Could your company be liable under a theory of copyright infringement? This paper highlights the scenario when contents of your Website are exploited by others without your permission or knowledge. The discussion is centered on copyright issues involved in the practices of linking, inlining and framing technologies which are normally being used on the Internet.

Copyright is a legal entitlement granted to creators of literary, dramatic, musical, and artistic works, as well as producers of cinematographic films and sound recordings. This legal right encompasses various privileges, including the reproduction, adaptation, translation, and communication to the public of the work. The composition of these rights may vary slightly, depending on the nature of the work. Along with Intellectual Property (IP), Copyright is a legal concept that safeguards the rights of creators and inventors. Copyright confers upon creators the exclusive legal right to reproduce, distribute, and exhibit their work, while IP comprises other legal rights such as patents, trademarks, and trade secrets. Copyright applies to a diverse range of creative works, including literary, dramatic, musical, and artistic works, as well as sound recordings and cinematographic films. Piracy is a worldwide issue that adversely affects various content industries, such as software, television, recording, and movies.

Copyright and IP laws play a crucial role in promoting creativity and innovation by safeguarding the rights of creators and inventors. These laws grant exclusive rights to creators and inventors, allowing them to financially benefit from their work. This encourages investment in research and development, leading to the creation of new ideas, products, and services. Without copyright and IP protection, creators and inventors may be discouraged from investing their time and resources into creating new works, resulting in a decline in innovation and economic growth. These laws also protect consumers by ensuring that they receive original, high-quality products and services instead of counterfeit or low-quality imitations.

Arid regions lie under the category of wastelands which are not being used to their fullest potential therefore, it almost barren. Hot arid regions are sparsely populated with human and animal population and experiences various biotic exploitation of the already very poor resources base. The scarcity of water poses biggest hindrance in limits the crop productivity as climatic factor. Yet, nature has bestowed the arid region fruits with characteristic qualities. Some fruit crops can grow successfully in such type of regions. Among these crops, cardia most suitable crop for cultivation under such type of arid climate. Some regional names of cordia are Pidar, Ponugeri, Maruvilli, Geduri, Spistan, Bhakar, Borla, Kalo Bohori (Nepali) etc. It is growing not only all over Asia but also nearly whole of the globe especially in tropical environment. In Indian sub-continent, it is growing from east Myanmar to west Afghanistan. It is grown in arid region and having numerous utilities. It is found in a variety of the forest of Rajasthan to moist deciduous forests of the Western Ghats and Tidal forest of Myanmar. In Maharashtra, it grows in moist monsoon forests also. In Rajasthan, its commercial plantations are being done in Pali, Sirohi, Udaipur, Jodhpur and Jalore districts.

Now, it is becoming popular as monoculture cultivation as well as under agroforestry system in arid region. It does not grow gregariously but is found growing singly in moist shady ravines and valleys. In areas with annual rainfall less than 500mm, it thrives along streams and depressions where moisture is available. The hot arid zone stretch 32 M ha or 0.32 million square kilometer long covering Rajasthan (62%), Gujrat (20%), Andra Pradesh (7%), Punjab (5%), Haryana (4%), Karnataka (3%) and Maharastra (0.4%). In these area fruits selection for cultivation must be cope up that their maximal growth period coincides with the period of water availability in the soil. Few of the xerophytes characteristics are: deeper root system, deciduous nature, reduced foliage, sunken of covered stomata, waxy coating or hairiness on leaf surface which minimize the evapotranspiration and makes plant adaptive to the hostile climate. These qualities are found in cordia plant which can grow in this area without any problem after management of some agro-techniques.

“Small is beautiful”, today we know that small is not only beautiful but also powerful. With the range of applications that nanoparticles find in varied fields of engineering and science, nanoparticles seem a promising option when compared to the conventional materials used. Nanoparticles are particles that have at least one dimension in less than 100nm range. They have a high surface to volume ratio and thus mass transfer and heat transfer properties are better than bulk materials. Recently; core/shell nanoparticles are finding widespread application. There is a class of core/shell nanoparticle that has its entire constituent in the nanometer range. Core/shell nanoparticles are nanostructures that have core made of a material coated with another material. They are in the size range of 20nm-200nm. Also, composite structures with these core/shell particles embedded in a matrix material are in use. The necessity to shift to core/shell nanoparticles is the improvement in the properties. Taking into consideration the size of the nanoparticles, the shell material can be chosen such that the agglomeration of particle can be prevented. This implies that the monodispersity of the particles can be improved. The core/shell structure enhances the thermal and chemical stability of the nanoparticles, improves solubility, makes them less cytotoxic and allows conjugation of other molecules to these particles. The shell can also prevent the oxidation of the core material. “When a core nanoparticle is coated with a polymeric layer or an inorganic layer like silicabecausethe polymeric orinorganiclayerwould endow the hybrid structure with an additional function/property on top of the function/property of the core hence synergistically emerged functions can be envisioned”.

Coriander aphid: Hyadaphis coriandri: Aphididae

Coriander aphids are yellow-green in color, dusted with grayish wax. They have short, dusky, slightly swollen, siphunculi (or cornicles). The Aphids form dense, damaging colonies on leaves, heads, and stems of their host plants.

In its native land, Florida, USA, the life cycle of the coriander aphid is similar to that of other host-alternating aphids. Overwintering eggs occur on other hosts.  A fundatrix (or stem mother) hatches from the egg in the spring. Her offspring are parthenogenetic, and the winged-females are spring migrants. They colonize summer host plants in the family Umbelliferae.
