Climate factors influencing

Temperature and humidity are the main climate factors influencing the development of Fusarium diseases of cereals. These factors show strong... 

Leaf gas exchange rates are highly dependent on local climatic factors influencing C02 diffusion and evaporation rates, especially temperature lapse rates. The dependency of gas-exchange parameters on local climatic factors and leaf anatomy may account for the wide variability in leaf stomatal responses and stable isotope composition over elevation transects found in different species and different regions.

Many factors influence the corrosion of metals in the atmosphere, including the natural phenomena that make up the vagaries of climate and weather. Of these, the feature of greatest importance is moisture in its various forms, since, other factors apart, the amount of corrosion that takes place is largely a question of whether and how long a period the surface of the metal is wetted ( time of wetness ). 

The role of meteorological and climatic factors and their variability. Ambient air quality (e.g., oxidant concentrations) and deposition that can affect the emissions to indicator relationship. Sampling frequency is also an important attribute of a monitoring program that strongly influences the ability to detect trends. 

Evans (1951) described land potential and measured it in terms of sustained yield of oats. The determining factors influencing yield were, as we have seen, soil type and climate, particularly rainfall. He then went on to calculate whether a particular farmer was achieving the optimal output, or whether he was under-achieving, or exploiting his land by over-production in the one case he was making less money than he could have and in the other case productivity would have quickly fallen as the soil lost both structure and nutrients. 

Many factors influence the production and composition of leachate. One major factor is the climate of the landfill. For example, where the climate is prone to higher levels of precipitation, there will be more water entering the landfill and therefore more leachate generated. Another factor is the site topography of the landfill, which influences the runoff patterns and again the water balance within the site. 

Because borrow soils will be mixed and modified during placement, the cover soil for an ET landfill cover, as constructed, will be unique to the site. However, the soil properties may be easily described. The design process requires an evaluation of whether or not the proposed soil and plant system can achieve the goals for the cover. Numerous factors interact to influence ET cover performance. A mathematical model is needed for design that is capable of (1) evaluating the site water balance that is based on the interaction of soil, plant, and climate factors and (2) estimating the performance of an ET landfill cover during extended future time periods.

At the continental- to subcontinental-scale the relative proportions of major minerals in soils are largely controlled by parent material and climate factors. In turn, the distributions of many major and trace elements are strongly influenced by soil mineralogy, especially the presence or absence of quartz (Eberl Smith 2009 Bern 2009).

In the Asian region with prevalent monsoon climate and heavy rain events during rain seasons, surface runoff plays the most important role in the environmental pathways of many pesticides. The major factors influencing the amount of pesticides carried away by runoff are as follows (Richter, 1999) ...

Financial considerations were not the only factor influencing job decisions. Some interviewees indicated that their job decisions were based on interpersonal relationships and the culture or climate of the employing organization. Sometimes academic advisors played key roles in these decisions. One Cohort III interviewee remarked My Ph.D. advisor was a good friend of the Research Director... 

Susceptibility of vegetation to air pollutant injury is reportedly influenced by many climatic factors, edaphic factors, genetic variability, and by structural and biochemical variations in the plant. Observed differences in susceptibility have prompted numerous attempts to prepare lists of plant species according to susceptibility or tolerance to specific air pollutants. It has become apparent that such lists are frequently inaccurate because the differential in susceptibility within a single variety or cultivar may be as great as that between species. 

The complex interaction between climatic factors, toxicant concentration, exposure duration, soil conditions and physiological characteristics determines the susceptibility of plant tissue and, to a large extent, influences the characteristics of the injury symptom syndrome produced. Distinct and relatively uniform symptoms may be produced repeatedly on susceptible members of the plant community if they are exposed under controlled-standardized conditions. But the extent of injury and a concomitant alteration in injury appearance usually occurs when there is a deviation in toxicant dosage, plant species or environmental condition. 

In irradiated potatoes, especially in some varieties and as a function of cultivating conditions of the raw material, after-cooking darkening may occur. This discoloration is attributed to formation of ferric-phenolic complexes. This phenomenon depends on the iron content, and is related to increased polyphenol formation and reduced citric acid levels, which are influenced by agronomic and climatic factors. Various technological measures have been developed to prevent this after-cooking darkening [23].

To evaluate the actual contribution to the total exposure from contaminants via tap water, two general factors have to be considered (1) the quantity of water consumed per person per day and (2) water-use habits. Under ordinary circumstances, an average adult consumes about 2-5 L of water per day, and this requirement is partly filled by ingesting liquids such as beer, soft drinks, etc. Furthermore, age, activity, and climatic conditions influence the amount of tap water ingested. 

Many factors influence quantity and type of inorganic constituents in fruits. Some of the significant factors are maturity, variety, season, location, production practices, and climatic conditions (170). Since these factors are of critical importance to plant nutrition, growth, development,...
