Etiology

Erysipelothrix rhusiopathiae.

Disease Occurrence

The disease is worldwide in distribution.

Host Range

Outbreaks of significant economic loss are in turkeys. Occasional outbreaks have been reported in pheasants, ducks, geese, guinea fowl, chukars, grebes and emus. Erysipelas also occurs in swine, sheep, sea mammals, fish and many wild animals. In humans (fish handlers, butchers, kitchen workers, turkeygrowers and veterinarians) it causes a localised inflammation called “erysipeloid”.

The venous drainage from the wall of the thorax is performed by the dorsal intercostal veins. These veins are distributed as below.

The dorsal intercostal veins are twelve pairs in number. Of these, the fourth to twelfth intercostal veins from right side and fifth to twelfth intercostal veins from the left side join the vena azygos.

The social area analysis model of urban structure incorporates all three aspects of city structure, namely concentric zones, sectors and multiple nuclei. It is a more comprehensive statement of urban forms. The model was developed by R.A. Murdie in 1969. According to this model, the physical space of streets, buildings and roads are superimposed by three dimension of social space (Fig. 8.1). The social criteria are the following:

Family Status

Family status indicators include population and age variables, house ownership and age characteristics, family size and marital status and other life cycle. These exhibit a concentric zonal or ring pattern with older, smaller renter households located near the city centre and owner occupied newer larger family households near the outer fringe.

Economic Status

Economic status tends to include measure of income, occupation and education. This portrays a distinct sectoral pattern with definite high income and low income sectors.

The purple passion fruit (Passiflora edulis) is a native of the rainforest margins in the Amazon region of Brazil. Passion fruit acquired its name from Spanish missionaries who thought that parts of the plant’s flower resembled different religious symbols such as the crown of thorns. Passion fruit grows on a vine in tropical regions. It has a tough, smooth, waxy rind that can be either yellow or purple. The flavour is like a cross between melon and guava. Passion fruits get sweeter as they shrivel. The fruit will quickly turn from green to deep purple (or yellow) when ripe and then fall to the ground within a few days. They can either be picked when they change colour or gathered from the ground each day.

ABSTRACT

In cocoa (Theobroma cacao L.) there are successful reports on the production of shoots from nodal segments under in vitro,the rooting was always inconsistent and mortality during hardening stage was very high. In the present study 20-30 per cent rooting was obtained in half strength MS supplemented with activated charcoal. Maximum rooting was obtained when the shoots were pretreated with IBA 5000 mg l^-1 for three seconds followed by culturing in the media.

Etiology

Yersinia pseudotuberculosis, non-motile at 37 C but motile at room temperature around 25 C. It is a disease of turkeys, ducks, geese, chickens, guinea fowl, and companion birds and free flying birds. It has also been reported in many species of mammals including man. In man, it causes symptoms of appendicitis. The disease has been reported in many countries. Body excretions of diseased birds or mammals that contaminate soil, food and water are the important factor in the transmission of the disease. The disease usually occurs as an acute septicemia of short duration, followed by a chronic focal infection.

Pore space or porosity : Porosity is an index of the relative pore volume in the soil or volume fraction of pores. Its value generally lies in the range of 0.3-0.36 (30-60%). Coarse textured soils tend to be less porus than fine textured soil, though the mean size of individual pores is greater in the former than in the latter. The total porosity, in any case, reveals nothing about the pore size distribution which itself is an important property.

Abstract

Twenty seven genotypes including two wild relatives of strawberry were evaluated for resistance against leaf spot caused by various fungal species viz.,Phyllosticta, Pestalotia, Hainesia lythri and Phyllosticta fragaricola under natural conditions. None of the genotypes was found to be resistant against leaf spot. However, the cultivar ‘Fern’ showed moderately susceptible reaction whereas the remaining genotypes were either susceptible or highly susceptible, suggesting the need for diversifying the germplasm either through open pollinated seedling selection or through hybridizing genotypes of divergent origin for resistance against leaf spot.

A case study was made in Geemarahalli village, Nanjangud taluk of Mysore district during 2009-10 to know the performance of women SHG involved in cultivation of tuberose.  JSS Krishi Vigyan Kendra which was started during 1994 analyzed the problems of farmwomen that they were unorganized in doing the field operations and were almost isolated in nature.  KVK initiated in formation of women SHGs in many villages and one of such village is Geemarahalli.  Ms. Rajamma was selected as group leader of the group and her contact with KVK was started since 1996 and still continued.  She is an innovative woman despite being illiterate.  Earlier she was doing tailoring and wire bag making. Later, she developed an interest to take up farming. She formed a Self Help Group called Triveni in her village which consists of 15 farmwomen.  In the beginning, they were involved in farm operations as contract workers.  During 2007-08, this group had come in contact with KVK and were imparted the training programmes on vermicompost production, horticulture nursery management, production of biological agents etc.  Later, the group came forward to learn the cultivation aspects of tuberose which has got good market at Mysore city.  To start this venture, the possession of land was the constraint for them and they overcome it by taking a 10 gunta land on lease basis. They were imparted series of trainings on tuberose cultivation at KVK.

Preservation methods are generally believed to be responsible for a depletion of naturally occurring antioxidants in food. Processed fruit and vegetables are expected to have a lower health protecting capacity than fresh ones. This is because, up to now, only selected and barely stable antioxidants of nutritional interest (e.g. ascorbic acid) have been commonly assessed as indicators of processing damage. On the basis of these supposed negative effects, in the past few years, the main tool for minimizing eventual processing damage was the strategy of ‘reconstitution’, achieved by the addition or the enrichment of the product with natural antioxidants.

It is well known that food processing can have many effects not all of which result in a loss of quality and health properties. Blanching also represents a useful tool in preventing enzymatic oxidations, which are the main cause of loss in naturally occurring antioxidants in raw material of plant origin. In fact, fruit and vegetables subjected to blanching retain most of their original antioxidant properties.

Lycopene appears to be a relatively stable compound during food processing but it has been reported that heating tomato pulp to produce paste, ketchup, juice and other products, can cause degradation of lycopene and other carotenoids. Other antioxidants naturally present in tomato, such as vitamin C, vitamin E, polyphenolic flavonoids and non-lycopene carotenoids, may play a role in preventing the degradation of lycopene. Thermal processes might break down cell walls and weaken the bonding forces between lycopene and the tissue matrix. Such disruptions in the cell wall fraction may enhance the release of phytochemicals from the matrix. This may make lycopene more accessible or more stable and thus increase the nutritional quality and antioxidant activity of product. An increase in carotenoids by thermal processing has also been attributed to enzymatic degradation which causes weakening in protein-carotenoid aggregates. Destruction of vitamin C is destroyed mainly due to oxidation reactions and the heat applied in the presence of air. The degree of loss of ascorbic acid is closely correlated to the drying temperature used for the production of the end product. The increase in the amounts of some phenolic substances having antioxidant activity was associated with two concomitant events: firstly, the thermally induced extraction of antioxidant molecules previously complexed or polymerized and secondly, the retention of active compounds caused by the inactivation of the enzymes involved in their catabolism.

Walter Isard had given the location theory in 1956 vided publication entitled, Location and the Space Economy. Isard has modified the Loschian schema, in the attempt to make it more realistic. Isard linked location theory to the general theory of economics through the substitution principle.

In economic theory, capital can be substituted for labour, for example. Similarly, the selection of a manufacturing site from among alternative locations can be viewed as substituting expenditures among the various production factors such that the best site is chosen. (Fig.10.1) provides one simple illustration of Isard’s substitution principle.

Primary particles tend to adhere under natural condition so as to form secondary unit called aggregates. It is very difficult to determine the diameter of the individual aggregated particle. So the mean weight diameter is calculated as a single value constant, which indicate the wetted average value for a group of aggregates.

Pigs are inherently prolific, and two farrowings per year under optimal management conditions should be planned. One boar must be kept for every ten sows for optimal fertility. Breed the animals at their most active heat cycle (12 to 24 hours of heat). After every 21 days, the sows come into heat. Proper feeding and handling promotes heat, which facilitates breeding and results in larger litter numbers. In addition to grains, there is fish meal, skim milk or butter milk feed can be administered 2-3 weeks before breeding to allow for a 200-300 gm/day increase in body weight. The normal gestation period for a sow is 112-115 days, and the usual litter size is 8-10 piglets. Larger litters with higher birth weights are produced by older sows.
