Family : Amaranthaceae

Flowering : October-December

Fruiting : December-January

Botanical description

The plant is an erect, straggling or subscandant herb. The leaves are ovate, elliptic, obtuse, acute and finely attached to the stem on both sides. The flowers are greenish white in colour, bracteolate having membranous blade and seeds are reddish brown in colour, sub-cylindric at apex and rounded at the base.

Soil is shaken with 0.15 % CaCl2 solution. Chloride ions displace adsorbed sulphate during extraction. Calcium ions suppress the extraction of soil organic matter and hence eliminate the contamination caused by extractable organic S.

Judgment sampling: Judgment sampling is utilized frequently during qualitative research to develop hypotheses rather than to generalize to larger populations. The research worker’s decision is used for selecting items which are considered as representative of the population in judgment sampling.

5.1. Origin and distribution

Adenoviruses have been found in several species of birds and animals. There are at least 12 serotypes of chicken adenoviruses. The chicken adenoviruses are host specific, meaning they will not infect other animal species. Avian adenoviruses are divided into three major groups. Members of each type may share group antigens, but there is no common antigen shared between types.

Karl Pearson’s coefficient: Karl Pearson’s coefficient of correlation (also simple correlation) is the most widely used methods of measuring the degree of relationship between two variables. This coefficient assumes that there is a linear relationship between the two variables; the two variables are causally related which means that one of the variables is independent and the other one is dependent; and a large number of independent causes are operating in both variables so as to produce a normal distribution.

Objective: To practice group discussion and understand the do’s and don’ts of group discussion process.

Overview: Group discussion is a form of discourse, which occurs when more than two people recognize a common problem, exchange and evaluate information and ideas. Their efforts may be directed towards a better understanding of the topic or solving a problem. Group discussion occurs in a face-to-face or co-acting situation. It is a democratic method in which equal opportunity is given to every participant to express his/ her opinion. In formal settings, group discussion takes place under the direction of leader. Group discussion is often used by academic institutions or employers to assess certain traits and skills of the participants. The number of participants usually is around eight, but there is no hard and fast rule. When being used as a method of assessment/ evaluation, the group is given a topic.

Objective: Aims to investigate and understand the distinguishing features of butterflies and moths, focusing on their unique traits and examples.

Jaboticaba : It is a Brazilian tree (Myrciaria cauliflora) of the myrtle family cultivated in warm regions for its edible purplish fruit.

Jack salmon / walleye : A large vigorous American freshwater food and sport fish (Stizostedion vitreum) that has large opaque eyes and is related to the perches but resembles the true pike sometime also called walleyed pike

Jaggery : Raw brown / unrefined brown sugar in lump made from palm sap.

Quail bronchitis (QB) is caused by group I (aviadenovirus). QB is an acute respiratory disease of bobwhite quail, occasionally with high mortality. Disease has sporadic occurrence many parts of the world. QB virus is closely related to the prototype CELO (chick embryo lethal orphan) virus, which is cause of high mortality in chicks.

Procedure

• Take 1 g soil in a 50 ml beaker

• Add 25 ml 1M KCL solution 

Latent Structure Analysis: Latent Structure Analysis shares both of the objectives of factor analysis to extract latent factors as well as an express relationship of observed (manifest) variables with the factors as their indicators and to classify a population of respondents into guanine types. This analysis is suitable if the variables involved in the study do not possess dependency relationship and happen to be non-metric.

Introduction, importance and scope of Canopy management

• The tatura trellis uses more water than other systems.
• Light interception ranges from 57 to 81% of available light.
• HDP increases light interception of 20% and 60%.
• Meadow orchard system affords more light than other conventional systems.
• The orientation of North to South intercept should be about - 89% of direct and 87% of diffused light.
• Summer priming in combination with dormant priming reduces light interceptor by 15%.
• In the bottom of 4m tall trees, the light is reduced to 10% of full sunlight.
• Light transmittance is a logarithmic function of the leaf area index.
• Photosynthetic Active Radiation (PAR) is from 380-720 nm.
• Photosynthesis to be about 60% of the maximum at 25% of full sunlight.

Objective: To practice case-based group discussion.

Overview: A case is a detailed description of anything that has happened in real life. In a case, real names are often changed to ensure confidentiality and protect the privacy, but it is not a fictitious account. A case presents a situation, or a problem and the learner is expected to suggest a solution based on the information given in the case. Case based group discussion is often used to test the analytical and reasoning ability of the participants. While participating in a case-based group discussion, the students should start by recognising and defining the problem. This is followed by listing as many solutions as possible with contributions from all the group members. In the next step, each solution is evaluated critically by the group members keeping in mind the information/ data/ facts given in the case. Finally, the best possible solution is put forth by the group. It is important to remember that there are no right or wrong solution as any option is often a trade-off.

? Consumption of seeds (dog/cat), Baits containing strychinine kept for foxes, rats, mice

? Cattle are more susceptible to strychnine poisoning parenterally than orally because strychnine is destroyed in the rumen

? Ingestion of birds or rats poisoned with strychnine and ingestion of strychnine treated seeds of peanuts, wheat (in human).

? In Seeds, 1.53- 3.24% total alkaloids out of which 50% is strychnine.

? Loganin (glycoside), Vomicine, α-colubrine, betacolubrine, pseudo strychinine (alkaloid), Brucine, strychnine and strychnicine (leaves), Brucine and small amount of strychnine (bark)

? Average amount of strychnine and brucine in nuxvomica seeds is 1.23 and 1.55% respectively.

? Strychnine- an indole alkaloid found in seeds of Strychnos nuxvomica is extremely stable and can be detected in specimens many years even after the death of animals.

? It is rapidly absorbed from the GIT and parentrally significant amount found in liver and kidney while small amount reaches CNS.

? Metabolized by hepatic MFOs and primarily excreted in urine within 10 hrs.

Objective: This practical aims to understand the taxonomic traits of Megaloptera and Planipennia, focusing on their unique features and differences.
