Climate tropical

Spices have become commercial products ia over 70 countries of the world and may be produced ia almost every country that can grow crops. However, many species of botanicals can be grown only ia particular climates or have particular soil requirements. The warm, moist, tropical climates foster the growth of more species than any other areas the traditional or tropical spices origiaated ia these areas. 

In desert or tropical climates skin dries into a hard mass that does not soften even when soaked in water. By shaping a skin to a desired form and then drying, however, useful articles such as dmm heads and shields can be made. Tanning for useful leather is not a simple skill. 

H2O) made by the older chamber process and was suitable for use ia tropical climates. Ia less developed or remote areas, bleaching powder may stiU be prepared oa a small scale by generating CI2 from Ma02, NaCl, and H2SO4, and treating it with hydrated lime placed on shelves ia an absorption chamber (245). 

Annatto Extract. The aimatto tree (Bixa orelland) is a large, fast-growing shmb cultivated in tropical climates, including parts of South America, India, East Africa, and the Caribbean. The tree produces large clusters of brown or crimson capsular fmit containing seeds coated with a thin, highly... 

Weathering in a tropical climate causes polyethylene containers to crack, polypropylene (PP) ropes to rupture, and ABS telephones to foil. Polystyrene (PS) and cellulose acetate films used as packing materials also fail due to weathering. 

They are used where prolonged exposure to high UV resistance is required, such as prestige building cladding in tropical and sub-tropical climates. 

The capacity of a glass vessel varies with the temperature, and it is therefore necessary to define the temperature at which its capacity is intended to be correct in the UK a temperature of 20 °C has been adopted. A subsidiary standard temperature of 27 °C is accepted by the British Standards Institution, for use in tropical climates where the ambient temperature is consistently above 20 °C. The US Bureau of Standards, Washington, in compliance with the view held by some chemists that 25 °C more nearly approximates to the average laboratory temperature in the United States, will calibrate glass volumetric apparatus marked either 20 °C or 25 °C. 

Structural type. The possible function of flavonoids as antiherbivore defense com-ponnds was discnssed, bnt Mears (1980b) found no correlation between complexity of flavonoid profile and latitnde, as might be the case if complexity of profile increases as one goes from temperate to more tropical climates with concomitant increase in insect predators. Althongh the nnmber of samples stndied was not large, there was a relationship between latitnde and complexity of pigment profiles in taxa restricted to calcareons snbstrates. No driving force for this apparent relationship is evident.

Although bromocriptine mesilate is sensitive to heat and light, it is stable for up to 3 years at ambient temperature (20) when stored in sealed polyethylene bags contained in twist-off amber glass bottles. In warm and tropical climate (30 °C/75 percent relative humidity) and under identical package conditions, it is stable for 1 year, however only for 3 months at 50 °C. 

If not properly protected, bromocriptine adsorbs up to 6 percent by weight of water in tropical climate.

The initial HMF content in all honey samples was lower than the allowed maximum limit of 40 mg/kg as recommended by Turkish Alimentarus Codex [17], for honey in general. These results contradict the observation made by some authors that the types of honey produced in subtropical climates have high HMF exceeding 40 mg/kg [18]. However, the European Union council directive also allows for a maximum of 80 mg/kg for honey from tropical climates. The HMF level in honey is said to depend on the type of sugar present in honey and the fructose glucose ratio [19]. The HMF formation results from the acid catalyzed dehydration of hexose... 

TPUs are naturally sensitive to light, UV and hydrolysis but special grades are marketed. Specific grades target applications in tropical climates.
