Remote Sensing in Oil Exploration

Remote sensing plays a significant role in the oil exploration industry. It refers to the use of sensors and instruments to gather information about the Earth's surface and its environment from a distance. This information can be used to locate and evaluate oil and gas deposits.

There are different remote sensing techniques used in oil exploration, including

Seismic surveys: This technique involves creating sound waves underground and recording their reflection to determine the subsurface structure. It is commonly used in oil exploration to locate potential oil and gas deposits.

Magnetic surveys: This technique uses a magnetometer to measure the magnetic field of the Earth's surface. Magnetic anomalies can indicate the presence of underground geological structures that may contain oil or gas deposits.

Gravity surveys: This technique involves measuring variations in the Earth's gravitational field, which can indicate the presence of underground geological structures.

Laboratory pipettes are classified by their method of liquid transfer. There are two types of pipette one is plastic which is made up of polystyrene and are essentially disposable and second one is glass pipettes are very resistant to chemicals. Glass pipette can be used frequently by washing, sterilising and dry heat sterilisation is also available. Some of the common types of pipettes are using in laboratory such as serological, volumetric, micropipettes, multichannel, and Pasteur pipettes. Serological and graduated pipettes are used for transferring various volumes, while micropipettes and volumetric types of pipettes are only considered for precise measurement and transfer. Multichannel pipettes are used for dispensing into multiple wells, and Pasteur pipettes are simple for transferring small amounts.
1. Serological Pipettes
• Also known as graduated pipettes, made of glass or transparent polystyrene they are calibrated with markings to measure and dispense varying volumes.
• Appropriate for cell culture applications, transferring liquids and mixing.
2. Multichannel Pipettes
• It is design to transfer multiple samples at once, often used for 96 well plates or pcr tubes.
• It can be manual or automated, with multiple heads for faster dispensing.
3. Volumetric Pipettes
• It is designed to supply for single and particular volume of liquid.
• Marked by single graduation for an exact volume, such as 1, 5, 10, 25, and 50 mL.
• Used in chemical reactions and analysis where accuracy is crucial.

Body condition scoring (BCS), although subjective in nature, is the only practical method of evaluation of body energy stores in dairy cows. The method of body condition scoring, originally proposed by Edmonson et al. (1987) and recommended by the NRC (2001) is described here. This method uses a 5 point scale, with BCS of 1 being extremely thin and a score of 5 being extremely fat. This system includes a combination of both visual appraisal and manual palpation on 8 separate body locations. Figure 1 shows the suggested BCS chart based on these locations. The assessor can score the cows using this chart with a fair accuracy, without much previous experience of scoring the cows. The scoring method is recommended for HF and Holstein crossbred cows.

Loss of BCS is expected during early lactation when a cow is mobilizing body fat in support of energy needs for lactation. Typical observed changes in BCS range from 0.5 to 1.0 condition score units during the first 60 days postpartum. A 1-unit decrease in BCS for a cow weighing 650 kg at calving (BCS 4) would provide 698 MCal of ME.That amount of ME is sufficient to support 564 kg of 4 per cent fat corrected milk.

Family : Moraceae

Flowering: March-June

Fruiting June-July

Botanical Description: It is a large sized tree with few short areal roots. Leaves are ovate or elliptic with 7-20×3.5-9 cm in size. The most distinctive aspect of this tree is the red, furry figs in short clusters, that grows directly out of the trunk of tree. The figs do carry hundred of flowers in it.

Introduction

In India, pistachio cultivation is mainly grown for its edible nuts and it is a deciduous tree in the family Anacardiaceae. On the tree, pistachios grow in grape-like clusters, and the shell has the pistachio inside. The leaves of the pistachio tree are pinnate and composed of five individual oval leaflets. The pistachio tree flowers are small, brownish-green in colour, and lack petals. Pistachio trees can reach up to 20 feet in the wild but are generally smaller under cultivation. It is a famous dry fruit, widely loved by people in India.

Common name    :    English- Betelnut
        Hindi- Supari
        Odia- Gua
Family    :    Arecaceae

Habit & Distribution 
The plant is a tree, (Fig. 11 a) naturalized and commonly cultivated throughout India.

General Character
The plant is perennial, grows up to 20 meters in height and 8-12 inches in diameter. The stem is solitary, slender and erect. The leaf of the plant is 1.5-2 meter long, pinnate with numerous crowded leaflets. Fruit is a coriaceous drupe, ovoid, 3.7-5 cm, smooth orange, with a single seed with truncate base. The plant flowers and bears fruits throughout the year.

In may cases, it becomes necessary to send the cells from one laboratory to another laboratory within or outside the country. The ideal method is to fill the flask containing cells at log/exponential phase with growth medium, tightly close the cap, seal it with parafilm and tape and pack it properly with polythene containing tissue paper and cotton. The tissue paper and cotton is used to soak the medium in case of accidental breakage. The polythene containing tissue culture flask having the adherent cell sheet should again be packed with thick paper. Finally, it is to be kept in a wooden/metal box or container.

When dealing with the evaluation of the feeds and calculating the requirements of energy and protein for ruminants, it becomes necessary to inter convert values among different systems and units. Since the accuracy of conversions/equivalents and formulae used for calculating the requirements vary with different systems/constants used, the conversion factors and formulae given here can be used only as guidelines for routine purposes in laboratory or farms in feed formulation.

14.1. Commission for Agricultural Costs and Prices (CACP)

Set up in January, 1965 in name of Agricultural Prices Commission (APC) on recommendations of Food grains Prices Committee headed by Shri L.K.Jha.

Prices for different agricultural crops by GOI on the recommendations of CACP are announced as minimum support prices, statutory minimum prices, procurement prices and issue prices.

Common feeds and fodders: An edible material which is ingested, digested, absorbed, assimilated by the animals for their benefit, is known as feed. As per the National Research Council, Dry forages and roughages are cut and cured. These are bulky feeds with low digestibility. Crude fibre is > 18 % and TDN is < than 60 % because of high cell wall content. Some of the common feed stuffs are: dry grass (hay), wheat straw, paddy straw, oat straw etcetera. Stovers [aerial part without ears and husk (maize) or aerial parts without heads (sorghum). Hulls and shells too. Pasture range plants, tree leaves and forages are either harvested or without harvesting (fresh) are also very good for feeding, for example: pasture grass, range plants, tree leaves, green forages. Concentrates have < than 18 % crude fibre and > than 60 % TDN. Feeds rich in protein (plant origin) are: Cotton seeds / cakes, Mustard cake, Groundnut cake. Whereas animal origin protein sources are: Skim milk, Fish meal, Blood meal. Feeds rich in carbohydrates (energy) in grains are: Maize, Oat, Barley. Whereas grain by – products are: Wheat bran, Rice bran, Gram husk, Pulse chuni.
Points to ponder
• Animals are sometimes said “to feed” or to eat, therefore to mean = “food for animal”. The old English root is fedan = “nourish, sustain or foster”.
• Fodders are harvested and taken to animals; whereas, Forages are browsed on by animals, while still on the land.
• Feed manufacturing refers to the process of producing animal feed from raw agricultural products; whereas, Fodder produced by manufacturing is formulated to meet specific animal nutritionrequirements for (i) different species of animals, (ii) different life stages. The idea is: to transfer the seed energy and the plant’s energy to the animal.
