Dried Grasses

Grasses are easy to collect to dry and use. When the seed-heads have formed, the grass is cut off just above the soil using a sharp knife. They are allowed to lie in a thin layer in the sun for a day or two, turning them over a few times. They should not be allowed to get too damp. After they are dried they are put into a plethora of uses. Bunches of dried grasses can make a wonderful addition to any home or office.

13.1 Introduction
Drying is the process of evaporation separating a liquid from a substance or mixture of components. Either solid or solid–liquid phase describes the product to be dried. The separation follows a solid and a gas phase pattern. “Milk Product” is a product derived from milk processing that might include food additives and other substances functionally required for the milk product as approved in the laws (FSSAI Milk standards). Made to increase the storage life of the product, lower bulk so as to cut packaging and shipping costs, etc., dried milk products are created.
13.2 Dried milk
“Dried milk or milk powder is the product generated by the removal of water by heat or the equivalent means, to produce a solid containing five percent or less moisture. Dried whole milk or whole milk powder (WMP) from whole milk; and from skim milk is known as Dried Skim Milk or Skim Milk Powder (SMP), or Non-fat Dry Milk (NFDM); respectively
13.3 Whole Milk Powder
Dehydrating milk from cows, buffaloes, or a combination of both or from milk that has been standardized results in whole milk powder. Up to 0.3% of the weight of the product might be calcium chloride, citric acid, sodium citrate, and sodium salts of orthophosphoric and polyphosphoric acids; also included butylated hydroxy anisole up to 0.01% by weight. The label does not have to list these additions. Milk powder must to have a fat level at least 26.0 percent and a moisture level no more than 5.0 percent. Measured as lactic acid, its overall acidity should not be more than 1.2 percent. The Coliform count should not be more than 90 per gram; the normal plate count should be just 50,000 per gram. For roller-dried goods and spray-dried goods, the solubility index shouldn’t be higher than 15.0 or 2.0.

Flowers and plants are associated with mankind from the dawn of civilization. In the modern era these have become an integral part of human life, as love for flowers and ornamental plants is a common natural instinct in human beings. The catchy flowers glowing and glowing in all their grandeurs with simplicity always make them tempting to wish the season to continue for never ending, but it may be beyond reach of human beings. However, the answer for it could be by producing and preserving ever-lasting or long-lasting flowers and other attractive ornamental plant parts. These are now becoming favorites especially with the adventurous flower lovers across the globe. The beauty and fresh look of cut flowers and cut foliage is generally lost due to microbial activities and biochemical changes thus these are retained only for a few days even by using the best techniques of post harvest management (Datta, 1999). The charm of dried ornamental plant parts can be maintained from a few months to years with lesser cost if protected from the damage of high humidity as in dried flowers, the microbial activities in the aging process come to stand still.

The main characteristics of dried ornamentals are novelty, longevity, aesthetics, flexibility and year-round availability. The dehydrated or dried ornamentals are generally inexpensive and are sought for their everlasting and attractive appearance globally (Smith, 2000). Being largely focused on the qualities of attractive flowers, living plants and plant parts, floriculturists generally pay little attention to dried and preserved flowers and plants. Therefore, these products remained overlooked and underrated throughout the world. These are overlooked in the sense that their considerable economic importance is generally unrecognized and these are underrated in the sense that their aesthetic contribution is largely discounted. In contrast to other areas of floriculture including post-harvest management, relatively very little public funded research and development projects were undertaken on the dried flower industry across the globe (Joyce, 1998). This has slowed the pace in optimizing the dehydration technology and quality of the produces. Privately funded research and development work has sustained, but such findings are usually kept secret and limited information are available to the common man. Thus, this component of floriculture industry has remained ill defined with respect to the processes, products and organizations in the developed and developing countries. As we see in major cut flower crops, there are defined standards available for judging the quality, however these are lacking in dried ornamentals. There is an urgent need to start war- footing efforts and awareness on the dried ornamentals to attract greater public support to conduct concentrated research and development with more professionalism in the trade of these products.

Dried Petals

Many types of dried petals are used for making pot pourii eg., land lotus petals, rose petals, mahogany petals, lily petals and lotus petals. Flowers are dried for everlasting beauty. They add an elegant touch to the room and are dried for everlasting beauty. Preserving blooms is a wonderful way to preserve memories and enjoy long lasting splashes of color. Many flower parts are used in dried form. A vibrant and thrilling range of dried petals are used to embellish greeting cards, folders, books, and other personal belongings.

Driftwood is wood that has been washed onto a shore or beach of a sea or river by the action of winds, tides, waves or man. It is a form of marine debris or tide wrack.

In some waterfront areas, driftwood is a major nuisance. However, the driftwood provides shelter and food for birds, fish and other aquatic species as it floats in the ocean. Gribbles, shipworm sand bacteria decompose the wood and gradually turn it into nutrients that are reintroduced to the food web. Sometimes, the partially decomposed wood washes ashore, where it also shelters birds, plants, and other species. Driftwood can become the foundation for sand dunes.

Introduction

In the process of creating a hole in the metal surface through a drill, we use a drilling machine. We use a tapper shank and parallel shank to tie the drill to the drill machine. We can also use a drilling machine to do extra experiments i.e., tapping rimming counter shrinking and counterboring. In simple language, we also say that a, it is a machine which is wildly used over world for making a circular hole in various metal workpiece for making desired design or structure.

Crop Water Requirements

In designing an irrigation system, the primary objective is to know the water requirement of crops. Water requirement of crops are determined either by f ield cultivation or by estimation through commonly used empirical formulae such as Blaney Criddle, radiation, Penman or pan evaporation method.

Definitions

Crop water requirement or evapotranspiration (ETcrop ): It may be defined as the rate of evapotranspiration of a disease free crop growing in a field of not less than one hectare under adequate fertility and water supply so that full productive potential can be achieved in prevailing environment. Evapotranspiration requirement of a crop refers the ETcrop and expressed in mm/day.

Reference crop evapotranspiration (ET0 ): It is the rate of evapotranspiration from an extended surface of 8 to 15cm tall green grass of uniform height, actively growing, completely shading the ground and not short of water. ET0 may be computed by using the empirical formulae and meteorological data for the specific period.

Introduction

Drip irrigation is an efficient method of application of water at the plant bottom at a rate nearly equal to the consumptive use rate of the plant, thereby minimizing the conventional water losses like percolation, runoff and evaporation from soil. It is a process of slow application of water on, above or beneath the soil by the surface, sub-surface, bubbler, and spray or pulse system. Fertilizer can also be applied with the drip water. Emitters or applicators are placed closed to the plants and used to spray water in the form of drops, tiny streams or miniature spray. In the drip system water applied from the point source advances in all direction in the soil outward from the source. Drip irrigation is essentially a low rate, low pressure, frequent and long duration application of water in plants root zone area.

Drip irrigation is also called as localized irrigation, trickle irrigation, daily f low irrigation, diurnal irrigation, drop irrigation, sip irrigation, and micro irrigation. A particular name is being popularized in any area depending on the choice of the people of that area. The International Commission for Irrigation and Drainage (ICID) has recommended the term micro-irrigation while the American Society of Agricultural Engineers (ASAE) has preferred drip irrigation. In India it is told as drip irrigation.

Micro irrigation normally called as drip irrigation was introduced in early seventies. Drip irrigation is one of the advanced methods of irrigation, by which water can be supplied directly into the root zone of the soil to achieve considerable saving of water through high water use efficiency, compared to surface irrigation method where water use efficiency is low due to losses in the water distribution system in the field. In micro irrigation method, water supplied at slow rate that is 1.0-2.0 kg/sq cm to the root zone of an individual plant through lets called emitters or drippers fitted with laterals pipes and filters at pump side. The success of micro irrigation is proven and efforts are being made in promoting the same extensively among the farmers in arid areas.

The hot arid regions of India are spread over about 31.7 million ha area mainly in the States of Rajasthan, Gujarat, Andhra Pradesh, Punjab and Haryana, which inhabit on an average 61 persons per square km making up a population of nearly 20 million peoples. The Indian arid zone is characterized by high temperature and low and variable precipitation which limit the scope for high horticultural productivity. However, these conditions greatly favour development of high quality production in number of fruits such as date palm, ber, pomegranate, citrus, aonla, bael, grapes and, guava. The optimized technologies and inputs could increase the existing low productivity. It is now realized that there is a limited scope for quantum jump in fruit and vegetable production in the traditional production areas. The amelioration of the extreme conditions is also considered vital for life support to the inhabitants of this area. The recent awareness regarding the potential of these ecologically fragile lands for production of quality horticultural produce has not only opened up scope for providing economic sustenance for the people of this region, but also for bringing new areas to increase production through horticulture.

The scope of expanding water supplies through the development of water resources is very limited since suitable dam sites are fewer, development costs are prohibited, and environmental concerns are too strong. This has led to the realization that saving on the use of water is an option for expanding the water supply.

2.1 Introduction

Water is the most precious gift of the nature and it is also the most crucial element for sustainability of the life in the earth. India is the largest user of freshwater in the world. India’s total water consumption alone is the higher than any other continents. The Agricultural sector is the largest consumer of water followed by the domestic sector and the industrial sector. The role of irrigation water as one of the most essential inputs for crop cultivation can’t be denied. As a traditional productive input, it ensures production by acting as an agent of insurance against inadequate and inconsistent monsoon. Ultimately the outcome provides agricultural production stability. Thus, irrigation is of prime importance in cultivation of vegetable crops as it ensures favourable water balance within the root zone in addition to natural precipitation. It fulfils the crop- water demand and improves the crop production and effectiveness of other agricultural inputs. It is also an important limiting factor of crop yield, because of its association with several factors of plant environment, which directly influence the crop growth and development (Yaghi et al., 2013). The various irrigation methods under different system of irrigation differ with regard to extent of control, timeliness and adequacy of supply of irrigation water for crop cultivation. Consequently, the economic benefits and the costs due to these irrigation methods vary among different irrigation systems. The dominant method of irrigation practiced in large parts of the country is surface irrigation (basin, border and furrow) where the entire soil surface is almost f looded without considering the actual consumptive requirements of the crops. Frequent over or under irrigation create the problems of water stress or water logging leading to reduced irrigation efficiency (less than 30%).

21.1 INTRODUCTION

High population pressure has forced us to plough 46 per cent of our country area for food production. The present productivity is 12.36 tonnes/ha of fruits needs to be raised to 40.0 tonnes/ha by using N : P₂O₅: K₂O with other inputs, since recommended ratio is 0.75:0.50:1.00 only.

Since cost of the inputs like fertilizers and manures are very high, hence, efficient nutrient management is essential for sustainable fruit production and protection of the environment from different types of hazards occurring due to misuse of costly fertilizers.

The soils of India and especially of arid and semi-arid regions are impoverished to plant nutrients. Considering economy, energy and environment, it is imperative to use nutrients effectively by adopting the appropriate doses proper, placement and correct timings of application and to sustain the available nutrients in soil at the optimum level.

Wound healing is defined as any breach in the continuity of skin. Regenerative pharmacology aims to develop new therapeutic module to hasten the healing. Present study was aimed to evaluate the wound healing efficacy of goat milk based ointment vis a vis its molecular pharmacodynamics in full thickness excisional rat model. 96 healthy male Wistar rats were equally and randomly divided into four groups i.e. group I served as Healthy control/Sham Operated, group II served as silver sulphadiazine treated group and group III and IV served as group treated with 0.5 % and 1% goat milk based ointment, respectively. Square shaped wound of ≈ 2×2 cm2 (400 mm2) was surgically and aseptically created on the back of animals till the depth of panniculus carnosus. Animals were examined routinely till 21 day of the experimental study and healing potential of goat milk based ointment was ascertained by planimetric analysis viz. digital photography, wound area measurement, wound contraction percentage and biochemical assay using hydroxyproline, total protein and DNA content at different intervals i.e. on days 3,7,14 and 21 of the study.

In 1920, a 30-year-old Czech writer Karel Èapek, wrote a play called “R.U.R.” (Rossumovi Univerzální Roboti or Rossum’s Universal Robots). For this dystopian work about a bad day at a factory populated with sentient androids, Èapek called the androids “roboti”, as suggested byhis brother Josef, a painter and writer. It was premiered in Prague on 25^th January, 1921.

Èapek was admired for his opinions:

My dear Miss Glory, Robots are not people. They are mechanically more perfect than we are, they have an astounding intellectual capacity, but they have no soul.

But surprisingly he was keen on gardening!

4.2.1. Gear boxes

It is a unit fitted after the clutch. Forms a part of transmission and provides speed and torque conversions from a rotating power source to another device using gear ratios. Its primary function is to change the speed of the tractor to cater to varying field, road and load condition. It also helps in reversing the tractor.

Gears are usually made of alloy steel. Since the tractor has to transmit heavy torque all the time, the best quality lubricants, free from sediments, grit, alkali and moisture, are used for lubrication. SAE 90 oil is generally recommended for gear box.

The description about gear boxes stated below pertains to major tractors manufactured in India. The number of teeth in each of the gear and the engagement between gears of the main shaft and the corresponding gear on the counter/lay shaft also change in different tractors evolved over a period of time. Hence, information hosted in this section is only indicative.

Sambit Sharma, Chairman, CTN Limited (CTNL) received a letter from the Chairperson of 3^rd Pay Revision Committee (PRC) for Public Sector Undertaking (PSU) of India. The letter inter alia sought feedback on existing Performance Management System (PMS) at CTNL and suggestion for its continuity or modification, if any. In past also, CTNL's suggestions on various human resources (HR) matters had been valued by the Committee and many of those suggestions were retained in their final recommendations to the Government of India. Mr. Sharma, off late, had heard many stories, both positive as well as negative, about the PMS within CTNL and was therefore contemplating to thoroughly review the system. He marked the letter to Ratish Agarwal, Director (HR), CTNL to take necessary action.

This chapter traces the history of the electric quadcopter commonly known as the drone, prior to its use in agriculture.

As long ago as 1493, the versatile Italian Leonardo de Vinci, painter, sculptor, machine designer often inspired by his observations of Nature, made a sketch in one of his little notebooks of a screw-like machine next to which he wrote in his mirror-handwriting:

If this instrument made with a screw be well made – that is to say, made of linen of which the pores are stopped up with starch and be turned swiftly, the said screw will make its spiral in the air and it will rise high.¹

Four centuries later, in 1863, the Viscount Gustave du Ponton d’Amécourt, President of The Society for the Encouragement of Aerial Locomotion by Means of Heavier than Air Machines, published a forty-page monograph in Paris, entitled “The Conquest of the air by propeller. Account of a new system of aviation.” In this he took the Greek words helico and pteron, meaning “spiral” and “wing”, and combined them into the word hélicoptère (helicopter). D’Amécourt and his friends were among those very few who were passionately convinced that the future of flying was with heavier-than-air machines. To prove their point, having built a fragile flying machine model driven by clockwork springs, they watched it ascend vertically for a few seconds to a height of less than 3 metres (10 feet), only to crash back to the ground.

Aerial photography is objective of getting panoramic view of earth surface to analyze the features of earth and their interrelation at particular time period which may be changed in further events. In this concerned, the observation may play a vital role in achieving the goals of photography. Undoubtedly it is widely used in social function and so on, but still awaited for scientific or research use. Drone can measure the geometry of ground surface at lower altitude with more accuracy in the form of visual feature in natural colour. flight height of drone mainly limits the large area coverage due to lower flying and drone can work perfectly at low altitude planning with good quality feature/photography.

OVERVIEW OF UNMANNED AERIAL VEHICLE (UAV) TECHNOLOGY
Agricultural drone technology employs drones equipped with cameras and sensors to assist farmers in monitoring crops, applying pesticides, and analyzing soil conditions. This technology assists farmers in making informed decisions, enhancing yields, and minimizing chemical application.
A drone is fundamentally a flying robot that can be operated remotely or autonomously through software-driven flight plans within its embedded systems, which integrate with onboard sensors and a Global Positioning System (GPS).
Drones are remotely operated or autonomous aircraft engineered to function without a pilot on board. They are also referred to as Unmanned Aerial Vehicles (UAVs). They has the capability to function alone or be managed by human operators.
• They have gained significant popularity in recent years owing to their extensive range of applications and uses. Drones are available in a range of sizes and configurations, from compact portable models to larger variants. They possess an array of equipment that enables optimal functionality.
• The fundamental components of a drone consist of motors, propellers, flight controllers, batteries, and remote control systems. The motor and propeller are essential for generating push to elevate the drone from the ground, whilst the flight controller functions as the drone’s brain, responsible for data processing and movement regulation.
• The battery energizes the drone’s electronic components, while the remote control systems enable the operator to maneuver the drone. The drone functions by an integration of electronic components and software algorithms.
