Concretions

Concretions are solid, compact mass of material, endogenous or exogenous in origin, found in tissues, body cavities, ducts or in hollow organs. Concretions are stone-like bodies commonly occur in urinary system, gall bladder and gastrointestinal tract. Concretions of endogenous origin are known as calculi while those formed from exogenous material are known as piliconcretion (Hair), phytoconcretion (plant fibres) and polyconcretion (polythenes).

Calculi

Calculi are formed due to deposition of salts around the nucleus/nidus consisting of either fibrin, mucus, desquamated epithelial cells or clumps of bacteria. Due to the gradual and repeated precipitation of salts, calculi become laminated. In the process of calculi formation, the inner structural arrangement gets shrink, producing a rough superficial surface. Calculi formation is more common in urinary system and in gall bladder of man and animals; however, they may also occur in salivary gland, pancreas and intestines.

Cost estimation is a critical step in the planning and implementation of conservation structures, providing a foundation for project approval, budgeting, and economic evaluation. For drop spillways—hydraulic structures used in soil and water conservation—the process involves calculating all expenses associated with materials, labor, and ancillary charges.
Drop spillways are engineered to safely transport excess runoff from higher elevations to lower ground levels, preventing erosion and structural degradation. Commonly used in agricultural watersheds, these structures play a vital role in controlling gully erosion, managing stormwater, and maintaining land productivity.
Accurate cost estimation includes:
• Quantifying construction materials such as concrete, masonry, reinforcement bars, and pipe outlets.
• Calculating labor costs based on the skilled and unskilled labor required for excavation, form, and structural assembly.
• Adding overhead charges, including land revenue, administrative costs, and potential audit expenses.
A detailed cost estimate ensures that the project remains within budget while meeting safety, durability, and environmental standards. It also aids in comparing alternatives and securing funding or approvals from governing agencies.
COMPONENTS OF A DROP SPILLWAY
Estimating the cost of different conservation structures involves analyzing both material and labor expenses specific to each type of structure. This process plays a vital role in project approval and economic assessment. It includes calculating material quantities, labor charges, and additional costs such as audit fees and land revenue.

INTRODUCTION

Libraries have become Library and Information Centers (LIC) and Knowledge Resource Centers (KRC). Many LICs and KRCs have stepped forward towards establishing Digital Libraries and Digital Repositories. These wings require the professionals with adequate qualifications and should have good command over the latest technologies. The trained candidates prior to their recruitment may immediately take up a project with a challenge. The professionals who are in service may enhance their skills through sponsorships to long term / short term programs.

In the present era, LIS is treated as multi-disciplinary subject and has integration with all newly emerging subjects. The other side, the LIS departments in the Universities have to respond properly (towards requirement) in incorporating suitable latest topics in their curricula and implement it very strictly. The research activity in LIS field in the country has to grow suitably along with the developed countries. In Andhra Pradesh, similar response is needed from the Government in providing and releasing funds to the state universities to start LIS departments. The preference has to be given by the State Government to LIS research in public libraries in proportionate with Science, Humanities and Social Science libraries. In future, it is expected that the LIS research should lead.

Introduction

Rice is known as the grain of life, and is synonymous with food for Asians. In addition to being a staple food and an integral part of social rites, rituals, and festivals in all Asian countries, it has a medicinal value too, which was clearly recognized by the medicine systems of the region. Ancient Ayurvedic treatises laud the Raktashali red rice as a nutritive food and medicine. The medicinal value of other rices such as Sashtika, Sali, and parched rice have been documented in the Charaka Samhita (c. 700 BC) and the Susruta Samhita (c. 400 BC), in the treatment of various ailments such as diarrhea, vomiting, fever, hemorrhage, chest pain, wounds, and burns.

According to late Dr. Richaria, the well known rice scientist, 4, 00,000 varieties of rice existed in India during the Vedic period. According to his estimates, even today 2, 00,000 varieties of rice exist in India - a truly phenomenal number. Farmers in every part of country have a deep knowledge of their own rice varieties, This has enabled them to harvest a crop even under the most severe stress situations. Traditional paddy varieties are location specific and has its own advantages viz. saline tolerant, drought tolerant, pest tolerant, used for specific purpose such as roofing material for houses etc.

The pineapple is the leading edible member of the family Bromeliaceae which encompasses about 2,000 species, mostly epiphytic and many ornamentals. Pineapple (Anans comosus (L) Merr), belonging to the family Bromeliaceae, is one of the most important commercial fruit of the world. Its pleasant characteristic aroma and taste make it a choicest fruit both for fresh consumption and processing.

Now known botanically as Ananas comosus Merr. (syns. A. sativus Schult. f., Ananassa sativa Lindl., Bromelia ananas L., B. comosa L.), the fruit has acquired few vernacular names. It is widely called pina by Spanish-speaking people, abacaxi in the Portuguese tongue, ananas by the Dutch and French and the people of former French and Dutch colonies; nanas in southern Asia and the East Indes. In China, it is po-lomah; in Jamaica, sweet pine; and in Guatemala often merely pine.

The region which includes Central and Southern Brazil, northern Argentina and Paraguary, is believed to be the place of origin of Pineapple. From here it has spread to all countries of the tropic and some parts of the sub-tropics. It has been introduced to India in 1548. The major pineapple producing countries of the world’s are Hawaiian, Island, Philippines, Malaysia, Thailand, Brazil, China, Kenya, Mexico, Taiwan, South Africa, Australia, India and Indonesia.

Cultivars: Kew or Giant Kew, Queen, Mauritius, Cayenne, Red Spanish, Singapore Spanish, Haricharanvita, Charlotte, Rothchild. In Assam there are two indigenous varieties–Jaldhup Desi and Lakhat, both of which fall in Queen group.

Plum belongs to the genus Prunus under family Rosaceae. The European plum are Prunus domestica and Japanese plums are Prunus salicina and hybrids. Mature plum fruit may have a dusty-white coating that gives them a glaucous appearance and is easily rubbed off. This is an epicuticular wax coating and is known as “wax bloom”. Dried plum fruits are called dried plums or prunes, although prunes are a distinct type of plum, and may have pre-dated the fruits now commonly known as plums. The major plum producing states are Himachal Pradesh, Jammu & Kashmir, Mizoram, Punjab, Tamil Nadu (Ooty) and Uttarakhand.

Cultivars/Varieties: Damson plum, Greengage plum, Mirabelle plum, Victoria plum, Satsuma plum and Yellow plum.

Uses

Plums are mainly used consumed as fresh fruits. They are also used widely for making jam, jelly chutney and squash. Certain varieties of European plum are specially suited for drying to produce prunes. Prunes are firm fleshed fruits of P. domestica cultivars having sugar content which can be dried whole without fermentation around the pit, to make a firm tasteful product that can be stored for long period.

Pomegranate (Punica granatum L.) belongs to the family Punicaceae and is one of the favaourite table fruits of tropical and subtropical regions. The fresh fruit is of delicate quality while its processed products are highly appreciative. It is now extensively grown in Arid regions. Pomegranate is in fact native to Iran and is extensively cultivated in Mediterranean countries. It is distributed in Spain, Morocco, Egypt, Afghanistan, Arabian countries, Pakistan, Myanmar, China, Japan, Chile, Argetina, Mexico, USA, Bulgaria, Italy, India and Iraq.

Cultivars: Important pomegranate varieties cultivated in India are Bhagwa, Ganesh, Alandi or Vadki, Dholka, Kandhari, Kabul, Muskati Red, Paper Shelled, Spanish Ruby, Ganesh (GB I), G 137, P 23, P 26, Mridula, Aarakta, Jyoti, Ruby, IIHR Selection, Yercaud 1 and Co 1.

Uses

The pomegranate is commercially grown for its sweet acidic taste arils. The fresh fruit has exquisite quality, while its processed products such as bottled juice, syrups and jelly are highly appreciated. Pomegranate is a delicious fruit consumed for its medicinal value. Its juice is sweet with pleasant aroma and is refreshing. The fruit is widely used for Ayurvedic and Unani medicines. Some of the commercial products of pomegranates are juice, squash, syrup, jelly. Anardana is obtained by drying the seed along with pulp and sun. The rind is used as a valuable tanning material. The flowers yield a red dye.

The artificial intelligence (AI) world is quickly growing as it reaches several different industries. You currently will see AI used for many different purposes from agriculture to automotive; with the passage of time you will see even more of it. Agriculture is one of the most important branches of the IT industry. Agriculture is an important industry and is a big part of our economy’s base. In terms of annual sales, the agricultural industry contributes to our economy almost 17%.AI is becoming a technical advancement that boost and protects crop yield, as climate change and populations rise. Here in this chapter basics of Artificial Intelligence have been discussed how it can be related to agriculture.

1. Introduction

Artificial Intelligence has become most prominent in current generation. Every field is utilizing Artificial Intelligence for their better results and which also result in saving a lot of time. As Artificial intelligence is boosting different sectors to increase the productivity and efficiency and its utilization across different sectors like in the field of CIVIL Artificial Intelligence can be used to analyze the structures of buildings, dams etc., and Artificial Intelligence solutions are assisting in so many ways to overcome the traditional challenges in every field.

I. What is Artificial Intelligence

Artificial Intelligence is one of the most prominent field of Computer Science Engineering which attempts to redefine the tasks which are carried out by humans in their daily life with better results and maximum accuracy. Artificial Intelligence is actually meant to ease the work of human where the word artificial states the work done without any human interference and intelligence states the capabilities like human brain to perform tasks. The field artificial Intelligence has given so many definitions from time to time which can be typically stated as

Fragaria is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. It is a low perennial creeping herb which is widely grown in temperate and subtropical regions of the world.

There are more than 20 described species and many hybrids and cultivars. Cultivated strawberries are based on two species, Fragaria chiloensis (L) Duch., native to the west coast of North America and Fragaria virginia Duch., native to eastern coast of North America. Hybrids of these two species are ancestors to all the modern strawberries. The most common strawberries grown commercially are cultivars of the garden strawberry, a hybrid known as Fragaria × ananassa. Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world.

The major producers of strawberries are USA, Mexico, Poland, Japan, Italy, Israel, Australia, New Zealand and Turkey. In India it was introduced during 1960’s and is grown to a limited extent in Jammu & Kashmir and Himachal Pradesh and some parts of southern India (Karnataka and Ooty).

Cultivars/Varieites: Tioga, Tufts, Surecrop, Fresno, Toro, Heidi, Hood, Northwest, Puget Beauty, Olympus, Ozark Beauty.

Introduction

Nature provides a wealth of genetic variation in both wild and cultivated plants. In the advanced selections conducted in developing superior crop varieties cultivated today agriculture represent only a small portion of the available gene pool. However wild species remain a reservoir of valuable genetic variation and represents a valuable source for exploitation of unexplored genetic variation for improvement of various agronomic traits. Most success has come from introgression of specific single gene controlled traits largely for disease resistance (Tomleyson, 2000 and Sergio et al., 2000). The identification of genes and co-adapted gene complexes that control complex agronomic traits such as adaptation to specific environmental stresses, crop quality, yield, plant architecture, flowering time (especially important for vegetable crops) has been less effectively addressed so far and remains a major and immediate challenge. Also, existence of low genetic diversity in breeding lines of many species used in various plant breeding programs is often resulting in development of insignificant improvement of the trait under investigation (Christopher, 2000). Understanding the spectrum, frequency and distribution of allelic variation in genes controlling such multiple genes controlled complex traits will improve our knowledge of exploitation of natural variation and promotes effective management and exploitation of functional biodiversity. In India efforts have been initiated in the exploitation, conservation of crop germplasm and technologies that are needed to fully exploit this natural diversity available in our major crop plants and their wild relatives. For example, centers that maintain diverse germplasm collections (both by ICAR and State Agricultural Universities nation wild are well established.

34.1. Aim

To conduct cut out analysis of canned fruits and vegetable products.

34.2. Theory

Cut out examination of canned products is conducted to evaluate the product whether confirming to FSSAI standards or not. Canned fruit and vegetables are evaluated for presence of vacuum or pressure in the can, drained weight, total soluble solids, presence or absence of preservative, internal condition of can product contents and presence or absence of fermentation for ensuring microbiological safety.

Different crops are grown in a field. Any plant growing in a place where it is not desired competing with the main crops, has to be weeded out and such plants are called ‘weed’.

Effect of weed menace The weeds

Reduce crop yield and production efficiency. It competes with the main economical crop for space, water and nutrients.

Reduce crop quality.

Hamper intercultural operations.

Reduce crop quality.

Obstruct the flow of water in the irrigation channels.

Exert allelopathic effect on crops.

Harbour insect and pests, which affect the main crop of interest.

Nursery is one of the important components of horticultural crop production. Nursery is place where young crop plants are raised under intensive care for later transplanting to the field. Nurseries may be classified as follows. On the basis of the irrigation facilities, the nurseries are dry or wet nurseries.

1. Dry Nurseries: Generally such types of nurseries are observed in forestry. It is maintained without any irrigation or artificial watering. The rab nurseries of Western Maharashtra, Karnataka and Gujarat come under this category. The rab or semi-rab nurseries are made in the plantation areas on small well-burnt patches of land usually 0.01 to 0.05 ha mainly for supplying teak stumps. The seeds are sown in lines 45 cm apart just before the onset of monsoon. Normally no elaborate beds are made, no fencing is made and no irrigation is provided as compared to other nurseries.

Government initiatives are pivotal in advancing natural feed management and sustainable livestock practices across India. As natural and organic farming gain recognition for their environmental benefits, numerous national and state programs are supporting farmers in decreasing their reliance on synthetic inputs, particularly commercial livestock feed. Flagship schemes such as Paramparagat Krishi Vikas Yojana (PKVY) and Bharatiya Prakritik Krishi Paddhati (BPKP) promote integrated, low-input farming systems by offering financial aid, farmer training, and implementation through cluster-based models. These schemes often incorporate livestock integration and development of natural feed resources.
Departments under the Ministry of Agriculture and Farmers Welfare, the Department of Animal Husbandry & Dairying (DAHD), and ICAR institutions actively encourage fodder production, feed preservation, and development of indigenous feed mixtures through research, on-ground trials, and skill-building programs. For instance, the National Livestock Mission (NLM) aids in fodder seed distribution, establishment of silage facilities, and training on scientifically sound yet natural feeding techniques. Institutions like Krishi Vigyan Kendras (KVKs) and State Agricultural Universities (SAUs) contribute through extension services, field demonstrations, and technical advice on formulating natural feed, utilizing medicinal plants, and conserving feed on-farm.
In recent developments, the government has promoted Farmer Producer Organizations (FPOs) and Self-Help Groups (SHGs) to facilitate collective feed processing, shared resource use, and marketing of value-added products like organic milk and free-range poultry. Similarly, the Rashtriya Gokul Mission supports the improvement and conservation of native cattle breeds better suited for natural feeding systems.
