Introduction
In the era of digital media consumption, smartphones have emerged as powerful tools for video creation and editing making it accessible to everyone, from casual users to professional creators. With advancements in mobile technology, users can capture high-quality video and audio and edit them seamlessly within mobile applications. However, one of the significant challenges in video production is achieving proper synchronization between audio and video tracks. This chapter explores the principles of audio synchronization, the importance of this process in video editing, and practical techniques for
achieving perfect alignment using smartphone applications.
Understanding Audio Synchronization in Mobile Video Editing
Audio synchronization, or “lip-syncing,” is particularly vital in videos where
dialogue, music, or sound effects are synchronized with visual cues. Accurate synchronization can help convey emotions, emphasize actions, and create an immersive experience. On smartphones, achieving perfect synchronization requires both intuitive tools and practical techniques to account for various factors, such as audio drift, frame rates, and video quality.
Smartphone applications for video editing typically support audio synchronization through visual audio waveform displays, alignment tools, and timing adjustments. These features empower users to manually or automatically adjust and align audio with visual footage.

Feeding standards are vital guidelines that specify the necessary nutrient amounts for animals’ growth, health, and production. These standards have evolved since the nineteenth century and are classified into three types: comparative, digestible nutrient, and production value. They provide daily nutrient requirements or percentages of the diet, depending on the feeding method. Precise feeding uses daily requirements, while ad libitum feeding employs percentages.
A. Comparative type
1. Hay standard: In 1810, German scientist Thaer revolutionized the practice of animal feeding by introducing a standard for comparing different types of feed. This standard used meadow hay as the reference unit and considered it equivalent to 91 lbs. of clover hay, 200 lbs. of potatoes, or 625 lbs. of mangels. This allowed for a more accurate measurement and comparison of feed options, aiding farmers in their feeding decisions. Prior to this, feeding practices relied on practical experience due to limited knowledge of feed composition and animal needs. However, with Thaer’s new standard, farmers were able to make more informed choices when it came to providing proper nutrition for their animals. This marked an important advancement in the field of animal husbandry and laid the foundation for further research and understanding in the years to come.
2. Scandinavian “feed unit” standard: In 1884, Professor Fjord introduced the Scandinavian feeding standard, which focuses on the feed unit. One pound of common grains like corn, barley, or wheat is considered one unit, with other foods valued relative to this. The standard recommends one feed unit per 150 lbs. of body weight, with an additional unit for every three pounds of milk produced.

Galangal is the dried rhizome or root of a plant, Alpinia galanga Linn. Willd. which grows mainly in the Eastern Himalayas and South-Western India. The plant is 1.8-2.1 meters high, and bears perennial rhizomes which are deep, orange-brown in color, aromatic, pungent and bitter. The fruits are about 13 mm long, constricted in the middle, and contains 3-6 seeds. The seeds are slightly pungent, with an aroma similar to that of the rhizome. Cut pieces of the rhizomes of this species are known as “Greater Galangal”. The rhizome of “Lesser Galangal” is smaller and reddish brown in color, and, has a stronger odor ansd taste. According to Guenther (1973) Galangal root is also known under the names of “Smaller Galangal” and “Radix galangal minoris”. The earliest reference to this spice is that of an Arabian geographer Ibn Khurdabah (869-895 AD), who included Galangal in a list of products from a country he refers to as Sila (which was undoubtedly China). Sometimes later, Plutarch made reference to the use of Galangal as a fumigating spice by the early Egyptians. In 1153, it was mentioned by Edrisi as an incoming spice into Ade, which was then the port used by the Egyptians for all Asiatic products. In his travels, Marco Polo mentions that it was produced fairly extensively in Kachanfu and Kinsai (Tonkin). Galangal is one of the spices which reached European markets relatively early, for it is mentioned along with Black pepper in the literature of the Middle Ages, where it received praise in various writings dealing with drugs, medicines etc. The source of the spice which was reaching the European market remained almost unknown until the last century, when in 1867, a plant of unknown botanical origin was discovered in the extreme south of China. The following year, Hance examined both dried and living specimens of the plant and was able to conclude that it was the same as the “Lesser Galangal” known to the pharmacists.

Abstract

Crop cultivation is a complex process and involves a set of activities like land preparation, planting, pest control, irrigation, nutrient management, harvesting, marketing, etc. Entire cycle of crop production requires multitude of information by the farmers. Despite many efforts over the years to disseminate and transfer agriculture knowledge to the stakeholders, large amounts of expertise and knowledge are still out of reach to most of them. Agriculture knowledge may be contained in the corporate database, or it may reside undocumented inside the brain of the researchers or even stored in locations unknown to the majority of the people in the organization. Large sections of the farming community, particularly the rural folk, do not have access to the huge knowledge base acquired by agricultural universities, extension-centers and businesses. In this respect the main challenge is to find this knowledge and apply it to the decision making process involved in agriculture development.

Abstract

Buffaloes are considered to be the principle milk producing livestock species in India and Surti is one of the well-defined buffalo breeds of India. The study on lactation curve and persistency is very much helpful to know the sustainability of the lactation. The present study is based on daily milk production records for 298 lactations from 130 buffaloes belonging to 15 sires. Lactation curve was prepared through Statistical Packages for Social Sciences programme. Two functions, i.e. gamma function and inverse polynomial functions were fitted to the daily milk yield records. Persistency was calculated through simple analysis in Microsoft Excel 2000 on the weekly records of the milk yield. Gamma function was found to be more effective as compared to inverse polynomial function with higher R2 value for all the four lactations, which indicated that gamma function can be effectively used to establish lactation curve and predict milk yield of animals on any day of lactation. The value of persistency ranged from 97.94% in fourth lactation to 98.56 % in first lactation, indicating Surti buffaloes as fairly persistent in milk production throughout the lactation.

Origin and history: Papaya has long been known as wonder fruit of the tropics and is one of the five major fruit crops of tropical world, papaya fruits throughout the year and a remunerative fruit crop which is grown in almost every part of the country. It gives maximum yield per unit and income next to banana. It is generally grown as fruit plant in kitchen garden, home garden or nutrition garden and later as commercial fruit. It is also planted as a filler plant in a fruit orchard. India is the second largest producer of papaya in the world after Brazil. It is a fruit native to tropical America and commercially grown in many parts of the world viz., Australia, Hawaii, Taiwan, Puerto Rico, Peru, Florida, Texas, California, South Africa, Pakistan, Bangladesh and India. In India, it was introduced by Portuguese in 1611. It is grown in Karnataka, Bihar, Kerala, Tamil Nadu, Assam, Gujarat, Maharastra, Andhra Pradesh, Madhya Pradesh etc.

The Genetic Basis for Protein Synthesis

Archibald Garrod proposed that some genes code for the production of a single enzyme

Beadle and Tatum’s experiments with Neurospora led them to propose the one gene-one enzyme hypothesis

During translation, the genetic code within mRNA is used to make a polypeptide with a specific amino acid sequence

Exceptions to the genetic code are known to occur, which include the incorporation of selenocysteine and pyrrolysine into polypeptides

Synthetic RNA helped to decipher the genetic code

The use of RNA copolymers and the triplet binding assay also helped to crack the genetic code

A polypeptide chain has directionality from its amino terminal to its carboxyl terminal end

The amino acid sequences of polypeptides determine the structure and function of proteins

Cellular proteins are primarily responsible for the characteristics of living cells and an organism’s traits

Introduction

The term, “non-governmental organization” or NGO, came into use in 1945 because of the need for the UN to differentiate in its Charter between participation rights for intergovernmental specialized agencies and those for international private organizations. At the UN, virtually all types of private bodies can be recognized as NGOs .They only have to be independent from government control, not seeking to challenge governments either as a political party or by a narrow focus on human rights, non-profit-making and non-criminal (Ali Mostashari, 2005). On the contrary India is one the poorest countries housing one third of the total world poor population. 43% of Indian children are malnourished, a third ofthe world’s total. Over 25% of Indians are illiterate, and more than 20 million children are out of school (Asheesh Bisht et al., 2013). India is a highly populated and predominantly rural country. It is classified as a country of medium human development, ranked 128th in the United Nations Development Programme’s Human Development Index 2007. Life expectancy is 63.7 years at birth, and four fifths of the population lives on less than $2/day. The adult literacy rate is 61 percentages. India has a long history of civil society based on the concepts of daana (giving) and seva (service). Numerous organizations were established during this period, including the Friend-in-Need Society (1858), Prathana Samaj (1864), Satya Shodhan Samaj (1873), Arya Samaj (1875), the National Council for Women in India (1875), and the Indian National Conference (1887). Mahatma Gandhi’s return to India in 1916 shifted the focus of development activities to economic self sufficiency.

Clouds play very important role on weather and climate. The formation of clouds takes place when water condenses in the sky. Clouds are visible accumulation of tiny water droplets and ice crystals in the Earth’s atmosphere. The moisture is always present in the atmosphere though it may not be visible. Clouds form when air becomes cooler until the water vapour present in it condenses to liquid form. The condensation over oceans occurs around solid particles like salt, dust, smoke etc. suspended in the atmosphere. The type of clouds depends upon temperature and wind. The clouds are classified based on physical appearance and the height at which clouds are formed (Fig. 7.1).

Introduction

Biofilm formation is a series of complex process and accomplished mainly in five stages -Reversibleattachment, Irreversible attachment or colonization,Proliferation, Maturation &Dispersion. Usually biofilms comprise 10% of dry mass that represent microorganisms while the rest 90%derived from the matrix of biofilm. Microbial biofilms are aggregates of microorganisms embedded in self-produced matrices and adhere to an abiotic or biotic surface. Firstly, Marshall et al. (1971) threw light on the concept of biofilms &it’s complexity was discussed by many researchers. According to Donlan and Costerton (2002) “Biofilm as a structured community of microbial cells enclosed in a self-produced polymeric matrix and adherent to a surface to interface, and to each other” still remains the most appreciated definition of biofilms (Mishra et al., 2022). Basically, microbial biofilms are complex, dynamic and three dimensional heterogeneous structures in which cells are interconnected by EPS (Extracellular Polymeric Substances). Biofilms are found to be resistant against UV light, metal toxicity, antimicrobials and other chemical agents like soaps, detergents, disinfectant and other cleaning agents. Future insight the immense need to implicate effective methods for elimination of biofilms from the environment.

Plantation Crops

Plantation crops occupy an area of around 4 million hectares which is about 2.8 per cent of the total cropped area. However, the export potential of these crops is high and they account for 27 per cent of total agricultural export. The common plantation crops include coconut, oil palm, areca nut, tea, coffee, cocoa, cashewnut and rubber etc. Various pests infest these crops at different stages and cause economic damage. The crop wise details are as under:

Coconut Coconut,

Cocos nucifera also known as ‘Kalpa Vriksha’, as all the parts of the tree are utilized in one or other way. India is the largest producer of coconut in the world. Kerala, Karnataka, Tamil Nadu and Andhra Pradesh accounts for 90 per cent production of coconut. The other states namely West Bengal, Odisha ,Gujarat, Assam and Bihar contribute around 10 per cent of the total coconut producción. Pests at different stages of crop growth infest coconut tres, resulting in significant economic damage.

Floriculture has become very important industry as a result of science based techniques and steady supply of improved plant materials. One of the major constraints of floriculture industry is non availability of large scale quality planting materials. Conventional methods of propagation can not meet the increasing demand of propagating materials. Micropropagation is perhaps the most widely used biotechnology tool for large scale propagation of floricultural crops. This economic proposition has led to intensive practical research to evolve tissue culture techniques for mass propagation and production of virus-free plant material.  Since most of the ornamental crops are highly heterozygous, their seed progeny is not true-to-type. Conventionally in these plants vegetative reproduction method is followed to produce genetically identical plants at commercial scale. But the main constrain of this method is that only a limited number of plants can be raised in a year from a single mother plant and often fail to meet the market demand. Therefore, most of the modern floriculturists follow the micropropagation technique for rapid multiplication of ornamental plants.

Synnoyms : Pseudorinderpest, Goat plaque, Goat catarrhal fever

It is a severe rinderpest like disease of small ruminants viz., sheep, goat and wild ruminants characterized by pyrexia, catarrhal inflammation of ocular and nasal mucous membrane, erosive stomatitis, enteritis and pneumonia. The disease is also called goat plaque, kata, pseudorinderpest and  stomatitis pneumo-enteritis complex. The current and standard name of the disease was chosen by the International Workshop of the disease in Ibadan, Nigeria, 1980.

1. Introduction

Over the centuries, the use of medicinal herbs has become an important part of daily life despite the progress in modern medical and pharmaceuticals research. It is estimated that 40% of the world populations depends directly on plant based medicine. India is one of the world’s 12 biodiversity centres. Herbal industry in India uses about 8000 medicinal plants. Indian export of raw drugs has steadily grown at 26% to Rs.165 crores in 1994-’95 from Rs.130 crores in 1991-’92 and this is likely to touch US $5 trillion by 2050. Thus, India has a great role to play, as supplier of herbal products not only to meet the domestic needs, but also to take advantage of the tremendous export potential.

Biotic stress related problems are important bottlenecks for the successful commercial cultivation of any crop. Medicinal plants are not the exception and are vulnerable to be attacked by several pests and pathogens resulting crop loss in terms of both quantity as well as quality. Therefore, the “health of these healthy plants” should be concerned. Without proper identification and prior knowledge of the pests and diseases, the management will be a waste of time and money and can lead to further plant losses.

Introduction

Corona viruses are a huge family of viruses that cause many chronic diseases. A novel corona virus is an advanced strain of virus that has not been formerly identified in humans. Accepted recommendations to avert the spread of disease include regular hand washing, covering of mouth and nose when coughing and sneezing, avoid close contact (social distancing) with anyone showing symptoms,etc. Since majority of the people, especially children are sitting inside their home the usage of digital platforms are also increased dramatically.

COVID-19 and the associated lockdown in the country, has made a significant impact on the life of the population, across boundaries. Roughly saying, it has been near to a year since the foremost case of corona virus was reported in India, which was reported on January 30th 2020. Today that is, on 10th December 2020, 69,383,534 corona cases were reported, 1,578,707 deaths and 48,155,526 cases were recovered globally. In India 9,768,643 corona cases were reported, Of which 141,817 deaths and 9,253,388 cases were recovered. Whereas in Kerala, 2562 deaths, 658633 confirmed cases and 596593 recovered cases were reported. The only fluctuations are in the statistics, but the conditions are the same in each day. Of this study, we aim to create awareness on COVID-19 through interactive and pleasure seeking games. This helps to make them aware about the severity of the pandemic and also improves their psychological health. Lack of awareness and the passive attitude of people is the major factor of this situation. Children and the older adults are the major two communities more convenient to disseminate the information and at the same time they are the most vulnerable groups to the corona virus. Children are more enthusiastic and older people are more precaution. By providing the same games for both age groups, the interaction between both becomes closer and thereby improves the mental well-being of both in a family. So that the games were most effective in all respects. Games are activities usually undertaken for fun and enjoyment, but it not only meant for fun but also gives edutainment. Games are an effective tool to disseminate information by entertaining way.

Minimal processing of fruits and vegetables
The technological development and modernization during recent years have resulted in in organisation coupled with Lifestyle modification and changes in dietary habits. This development and Organisation have made it easier to meet the requirement of processed food. Processing of fruits and vegetables effects shelf life providing ready to eat food with similarities to fresh product. Before the food Industries shoulder a bigger responsibility of utilising a novel technology to produce safe food without detrimental effects on quality. The industries need to who built biological (enzymatic / fomentation and biopreservation and Engineering solutions like non-thermal high-pressure treatment, cook chill, microencapsulation, vacuum impregnation etc. For the adoption of de - constructive culinary techniques such as 3D food printing and Molecular gastronomy as well as developments in nutrigenomics and digital technologies may facilitate novel product format, personalization, and access to niche market. Concretely, e - operating movement from Naresh mint to health improvement in present conditions demand or shift from defensive market oriented offensive market developing strategies including collaborative networks with Research Organization.
It is also defined as any fruit and vegetable that has been subjected to different processing steps (e.g. peeling, trimming, cutting, washing, disinfection rinsing etc.).

Dry matter intake (DMI) is crucial for animal performance, especially in cattle. It ensures that animals receive the necessary nutrients and energy for metabolic functions. Cattle have complex digestive systems with unique metabolic functions. Variations in feed intake are essential throughout the growth cycle to maintain a balance in response to metabolic and environmental challenges.
Limitations in feed intake can lead to nutrient deficiencies, impacting growth rates and overall profitability. Feed stress can also result in health issues and digestive disturbances.
Importance of Predicting Dry Matter Intake (DMI) in Cattle Using NRC Guidelines
Predicting Dry Matter Intake (DMI) in cattle is crucial for managing livestock health, productivity, and economic efficiency. The National Research Council (NRC) offers guidelines to estimate DMI, aiding producers in optimizing feeding strategies. Here’s why predicting DMI is essential:
1. Optimizing Nutrient Intake
• Meeting Nutritional Needs: Accurate DMI prediction ensures cattle receive sufficient energy, protein, vitamins, and minerals for maintenance, growth, lactation, or reproduction.
• Avoiding Deficiencies: Inadequate feed can result in poor health, reduced production, and reproductive issues.
• Preventing Overfeeding: Excessive intake can lead to health problems like acidosis, obesity, or metabolic disorders.
2. Improving Productivity

World trade of fresh cut flower is increasing day by day. Fresh flowers lose their freshness and quality both during travel and also during and after arrangements due to flower specific short vase life. Such deficiencies can be ameliorated through application of nutrient additives to vase water. Use of preservative solutions has been known for many years to increase the vase life of cut flowers. Different methods like use of holding, pulsing and bud opening solution, growth regulators, gamma irradiation, pre-cooling, cold storage, packaging etc. are already in practice in the flower trade to ensure the garden fresh quality of flowers to consumers (Singh et al., 2001). The floral business is expanding in a big way, nationwide.  Sales of cut flowers are rising faster through retailers as every state has entered into development of supermarket chains. Cut flower sale through retailers is  a booming business. Retail growers and Wholesale growers are the major players in our country for domestic market. Retail market suffers from logistic bottlenecks. Retailers do not have any background scientific knowledge to increase the vase life of cut flowers. Flower buyers are very choosy and prefer quality bloom with longer vase life.
