Though oil production began there in the next decade antimicrobial resistance research buy discount zyvox 600mg on line, the first mention of oil was written in the records of Mission San Diego de Alcala in 1803 as described by Father Lasuen bacteria article generic zyvox 600 mg with mastercard. By the 1900s antibiotic eye drops for stye purchase 600mg zyvox with visa, California olive oil production had met the competition from imported olive oil and American vegetable oil and antibiotics xorimax buy generic zyvox 600mg, in an effort to survive, the canning olive industry was born. During the 20th century, the California canning olive occupied a strong market position in America, with olive oil as a salvage industry. Currently, a renewed emphasis in health benefits of monosaturated olive oil has lead to a resurgence of olive oil production in California. The olive tree has been used widely for shade around homes and as a street tree in cities. A smaller collection exits at the United States Germplasm Repository at Winters, California. Floral initiation occurs by ally mature in September or October (ready for the California black-ripe or green-ripe process), and physiologi- November (Pinney and Polito 1990), after which, flower cally mature in January or February. Unlike deciduous fruits with a short ally mature by October, and if harvested and stratified at that induction-to-initiation cycle, induction in olive may occur as early as July (about 6 weeks after full bloom), but initiation time it will achieve maximum germination (Lagarda and is not easily seen until 8 months later in February. When the fruit is physiologically mature by microscopic and histochemical techniques reveal evidence January, seed germination is greatly reduced. The origin of olive is lost in prewritten ing all the flower parts starts in March. In experiments with the cultivars grown in California, optimum flowering occurred when the temperature fluctuated daily between 15. In addition to winter chilling, inflorescence formation requires leaves on the fruiting shoots. The occasional occurrence of hot, dry winds during the blooming period has been associated with reduced fruit set. Prolonged, abnormally cold weather during April and May, when the olive flower buds should be developing rapidly, can have a detrimental effect on subsequent flowering, pollination, and fruit set. Such weather occurred in California in the spring of 1967, delaying bloom by several weeks and leading to flower abnormalities and a crop of only 14,000 tons, the lightest in modern California history. At full bloom, flowers are delicately poised for pollination, when some 500,000 flowers are present in a mature tree; a commercial crop of 7 metric tons/ha (3 tons/ac) or more can be achieved when 1 or 2% of these flowers remain as developing fruit. By 14 days after full bloom, most of the flowers destined to abscise have done so. By that time, about 494,000 flowers have abscised from a tree that started with 500,000 flowers. Perfect flowers, those with both pistillate and staminate parts, normally consist of a small calyx, 4 petals, 2 stamens and filaments supporting large pollen-bearing anthers, and a plum-green pistil with a short thick style and a large stigma. Perfect flowers are borne apically in an inflorescence, and within the typical triple-flower inflorescence the middle flower is generally perfect. Cultivars vary, but most abscission occurs soon after full bloom and final fruit set nearly always occurs within 6 weeks of full bloom. Further fruit abscission can result from pest infestation and environmental extremes. When trees have an inflorescence at nearly every leaf axil a commercial crop occurs with 1 to 2% fruit set; with a small population of inflorescence, a commercial crop may require 10% fruit set. Here the interfruit competition for raw materials differs from that of normal olive fruits. Shotberries mature much earlier than normal fruit and may be more prevalent when conditions favor a second large crop in succession. At that time, the endosperm begins to solidify and embryo development takes place, leading to embryo maturity by September. The fruits begin changing from the green color to yellow-white (straw) and accumulate anthocyanin from the distal or base end. The purple to black color eventually bleeds into the mesocarp, signaling fruit overmature for the California black-ripe or green-ripe processing.

Under the Central Study Scenario bacteria en el estomago generic zyvox 600 mg otc, wind power capacity additions lead to land-based lease payments that increase from $350 million in 2020 to $650 million in 2030 antibiotics for uti yahoo answers generic zyvox 600 mg on line, and then to $1 antibiotics for acne keloidalis nuchae discount 600 mg zyvox,020 million in 2050 antibiotic quality premium generic 600mg zyvox mastercard. Property tax payments associated with wind projects are estimated to be $900 million in 2020; $1,770 million in 2030; and $3,200 million in 2050. Under the Study Scenario, the land area occupied by turbines, roads, and other infrastructure for wind development equates to 0. For comparison, this area equates to less than one-third of land area occupied by U. Land area occupied by wind power plants (accounting for requisite turbine spacing and typical densities) equates to less than 1. Land surrounding wind power plants is typically able to support other land uses, such as ranching and farming. Continued wind deployment will need to be executed with sensitivity to the potential impacts on avian, bat, and other wildlife populations; the local environment; the landscape; and communities and individuals living in proximity to wind projects. When wind power is a more significant part of the electricity generation portfolio, as is the case in the Study Scenario, electricity system costs are less sensitive to market fluctuations in fossil fuel prices. In addition, deployment and operation of wind power plants reduces demand for fossil fuels, including natural gas, leading to lower fuel prices within and outside of the electric sector and supporting cost savings for consumers. Note: Cumulative costs and benefits are reported on a Net Present Value basis for the period of 2013 through 2050 and reflect the difference in impacts between the Central Study Scenario and the Baseline Scenario. In particular, offshore wind offers the ability to reduce wholesale market power clearing prices and consumer costs in transmission-congested coastal areas, supports local jobs and port development opportunities, and offers geographic proximity to densely populated coastal regions with limited renewable power alternatives. Distributed wind applications, including customer-sited wind and wind turbines embedded in distribution networks, offer a number of unique attributes relevant to the Wind Vision. On-site distributed wind turbines allow farmers, schools, and other energy users to benefit from reduced utility bills, predictable costs, and a hedge against the possibility of rising retail electricity rates. At the same time, decentralized generation such as distributed wind can benefit the electrical grid. Overcoming these costs and achieving the Study Scenario would require an array of actions (detailed in Chapter 4), but analysis also suggests that robust deployment of wind offers the opportunity to realize a range of additional benefits. Based on current estimates, these benefits exceed the expected near- and mid-term investments and other costs that might result from continued growth of wind energy, across nearly all analyzed scenarios. Critics argue that the costs associated with deployment and operation of wind power offset the potential benefits. This chapter informs both perspectives by providing a detailed accounting of various impacts associated with wind deployment under the Wind Vision Study Scenario. While Chapter 2 is a retrospective analysis, Chapter 3 provides an assessment of potential future impacts. Changes in electricity rates, annual electricity consumer costs or savings, and cumulative system expenditures are quantified and reported based on a range of future fossil fuel prices and cost trajectories for wind technology. Issues related to electric system reliability, operations and markets, and public acceptance and local impacts are also considered and discussed. The Wind Vision impacts assessment relies on scenarios of future wind deployment to estimate incremental impacts. As discussed in Chapter 1, the Study Scenario uses prescribed wind energy penetration levels of 10% by 2020, 20% by 2030, and 35% by 2050, a portion of which is assumed to be offshore wind. Impacts from the Study Scenario are compared with the Baseline Scenario, which holds wind capacity constant at year-end 2013 levels. This approach allows for the quantification of impacts from all future wind deployment. More comprehensive discussion of the development of the Study Scenario and the Baseline Scenario is in Chapter 1. In addition to detailing the impacts assessment and general quantification of costs and benefits, this chapter discusses the electric sector modeling methods and relevant modeling inputs. Each of these sections is based on a comparison of the Study Scenario with the Baseline Scenario. Given uncertainties about future wind energy costs as well as the cost of fossil generation, sensitivities are also considered in order to provide further insight. The focus is principally on a comparison of the Study Scenario under central conditions. Percentage wind energy penetration is calculated as the share of total wind generation relative to total end-use energy demand.

Some red maple seeds may germinate without stratification antibiotics on factory farms buy 600 mg zyvox mastercard, but stratification is necessary for seeds from some populations (Abbott 1974; Farmer and Cunningham 1981; Farmer and Goelz 1984; Peroni 1995; Wang and Haddon 1978) antibiotic dental abscess discount 600 mg zyvox free shipping. The group represented by sugar and bigleaf maples requires 30 to 90 days of stratification virus replication cheap 600mg zyvox amex. Germination paper antibiotics for uti vomiting generic zyvox 600 mg otc, sand, perlite, and sphagnum moss were all suitable stratification media for sugar maple seeds (Carl and Yawney 1966). To assure that seeds have been stratified long enough, it may be advisable to wait until the first germinants appear before moving them to warmer temperatures to increase germination rate or sowing in the nursery. The species that exhibit delayed germination are, under field conditions, exposed to warm and cold conditions and thus a warm period of incubation followed by cold stratification may stimulate germination. These species may also germinate better after a treatment that physically breaks the seed pericarp and testae (tables 5 and 6). Soaking seeds in warm water for 1 to 2 days is often recommended when they are completely dried out and the seedcoat has become very hard (Browse 1990; Dirr and Heuser 1987; Vertrees 1987). Seeds may go through at least 1 warm/cold cycle before germinating under field conditions. Although most species have their best germination at higher temperatures within the optimum range (table 6), this is not always the case. Studies with red and striped maples have shown that, for seeds from some sources, germination is faster at lower than at higher temperatures (Farmer and Cunningham 1981; Farmer and Goelz 1984; Wilson and others 1979). Germination occurs on a wide variety of substrates and a full range of light conditions (Burns and Honkala 1990; Fischer 1990; Olson and Gabriel 1974). Under field conditions, germination often occurs in association with leaf litter and other organic substrates on relatively undisturbed seedbeds. Germination paper, sand, perlite, and sphagnum moss support good germination in controlled environments. Red maple was shown to be more sensitive to the acidity of a substrate than sugar maple (Raynal and others 1982). The morphological and physiological basis for seed dormancy in maples varies among species and includes pericarp-and-seed-coat-imposed dormancy and embryo dormancy (Farmer 1996; Young and Young 1992). There may be little relationship between dormancy of the mature seed and that of a seed with a fully developed embryo that is not yet mature in a biochemical sense (Thomas and others 1973). Thus for some species it may be best to collect and sow immature seeds as suggested by Vertrees (1975, 1987) for vine and Japanese maples and more generally by Dirr and Heuser (1987) for species with the third germination pattern mentioned above. The type of dormancy imposed by the pericarp and seedcoat (such as that in vine and striped maples) may be released by removing the pericarp and all or part of the testae (figure 2) or by physically breaking the pericarp without actually removing the embryo (table 5) (Wilson and others 1979). Some of the delayed field germination described above is caused by the impenetrability of the seedcoat after embryo dormancy has been released (Dirr and Heuser 1987; Wilson and others 1979). Bareroot seedlings seem to be the most common when all species of maples are considered. Pre-sowing treatment and sowing time are based on the characteristics of the seeds being sown, convenience, and experience. Cutting tests or x-radiography to determine the presence of embryos are advised for some of the introduced species because poor seed quality is common (Dirr and Heuser 1987; Hutchinson 1971; Vertrees 1987). The information reviewed above on dormancy and germination pattern suggest a number of options for sowing. The least amount of seed handling is required when seeds are sown immediately after collection and allowed to stratify "naturally" before germination. Notes: Germination rate indicates the number of seeds germinating in the time specified and total germination all of the seeds germinating in the test. Tetrazolium tests could be used to determine if seeds are alive; knowing this one can sow and wait several years for seeds to germinate. Because the delay in germination appears related to a very hard pericarp, removing the pericarp can improve germination.

In noble fir virus 102 fever toddler buy 600mg zyvox amex, germination increases to a peak antibiotics for dogs lyme disease discount 600 mg zyvox otc, accompanied by an increase in seed dormancy (Edwards 1969 antibiotic resistance of bacteria buy zyvox 600 mg fast delivery, 1982a) pediatric antibiotics for sinus infection buy discount zyvox 600 mg on-line, then levels off before seed dispersal (Edwards 1969; Franklin 1965; Rediske and Nicholson 1965); a similar trend occurs in Turkey fir (Beskok 1970). In contrast, in grand (Pfister 1966; Snyder 1976) and Fraser firs (Speers 1962) germination continues to increase right up to seed dispersal. For this reason, seeds should not be removed from fir cones-particularly cones collected early-immediately after collection, because low seed viability may result (Edwards 1969; Rediske and Nicholson 1965; Speers 1962) due to curtailment of the second phase of ripening. The period for cone collection, from the time organic accumulation ends until seed dispersal begins, typically ranges from 4 to 6 weeks, depending on location. Calendar dates are unreliable and vary with locality-especially elevation-and weather patterns, but if cone storage facilities are available, collections in the West may begin by mid- to late-August. Knowledge of local ripening conditions (degree-day summations are useful) and the use of the few known ripeness indices (table 6) can aid the decision to begin collecting (Edwards 1982a). In many tree genera, not all fruits mature simultaneously, maturation date varying among cones on the same tree (cones on the southern aspect of the crown generally ripening earlier), among trees within the same stand, from stand to stand in the same year, and from one year to the next (Edwards 1980a; Franklin 1965). The extent to which collections can be made in advance of seed dispersal is largely governed by the fact that fir seed development ceases if the cones are detached from the parent tree too soon, especially if the primary organic-accumulation phase is incomplete. Early-collected cones are more sensitive to handling method, but this sensitivity declines in later collections (Edwards 1980a). In firs, cone and seed color (common maturity indices in many conifers) may be more closely related to seed source and to individual parent tree than to ripeness. For example, mature cones of white fir may be either green or purple, with green cones having (on average) 25% fewer viable seeds, and the seeds weighing 15% less, than seeds from purple cones, although there were significant interactions with elevation of the seed source (Farris and Mitton 1985). Similarly, in the former Yugoslavia, mature seeds of white fir from violet cones germinate better than those from yellow cones (Stilinovic and Tucovic 1971). Quality of Siberian fir seeds is better from trees with light-green cones than that of trees with dark-green cones (Kirgizov and Mosin 1980). Progressively southern sources of European silver fir in Bulgaria have darker colored and more germinable seeds (Gagov 1973). Nevertheless, workable indices of fir maturation have been devised for some species based on changes in cone color, seedcoat color, or the development of color in the seed wing (table 6), although this remains subjective and depends on the experience of the collector (Rudolf 1940). When cones of noble fir in Denmark begin to change from green to yellowish brown and bend down the branches because of their weight, natural seedfall is 2 to 3 weeks ahead; thus at the first signs of cone scale separation, the cones are collectable (Dalskov 1960). Two interrelated parameters-cone moisture content and cone specific gravity-are more objective and reliable indices (Rediske 1961). There is some general agreement (table 6) that maturity is reached when specific gravity of cones has fallen below 0. Either of these 2 parameters must be measured only on freshly picked cones, and because cone moisture content is not easily determined in the field, specific gravity is usually the measurement of choice. Thus, if cones of white and red firs (and of other conifers) float in kerosene, a 50:50 mixture of kerosene and linseed oil, or any mineral/ lubricating oil of specific gravity 0. However, cone specific gravity is of little use in judging maturity in Japanese fir (Yanagisawa 1965). Although no documented use of the following attribute has been found outside British Columbia, one criterion for judging when to begin fir cone collections is to allow a sample of longitudinally cut seeds to dry out overnight at room temperature. Then, if the megagametophyte tissue shows very little or no shrinkage away from the testa in most (if not all) of the seeds, they are sufficiently well developed for cone collections to begin (Dobbs and others 1976; Edwards 1980a, 1982a; Eremko and others 1989). Shrinkage of the megagametophyte indicates that the seeds are still high in moisture content and that collection should be delayed. The ratio of embryo length to the length of the cavity in the megagametophyte (figure 10) is also widely employed in British Columbia for judging when to collect (Eremko and others 1989). Embryos do not have to be fully elongated to be germinable, but seeds with embryos less than 50% extended germinate less vigorously and predictably. Because megagametophyte tissues do not mature as quickly as the embryos, collections should be delayed until these tissues have achieved a firm consistency (similar to the meat of a coconut), that is, they have lost their earlier watery, translucent appearance. Megagametophyte tissues will then exhibit little or no shrinkage or curling and retain a relatively firm, fresh appearance when longitudinally sliced seeds are left uncovered overnight at room temperature. The current prescription is to delay collections until embryos are at least 90% extended (figure 10), by which time the megagametophyte tissue has matured sufficiently also (Edwards 1982a; Eremko and others 1989) (table 6).
