Abstract:
Bract edge burn (BEB) is a serious commercial problem, and a cooperative trial with six cultivars was conducted at the above research locations and in commercial greenhouses in the respective areas. `Success' and `21-91' had less BEB than `Celebrate 2', `V-14 Glory', or `Supjibi'. BEB symptoms increased with time during postproduction. Number of bracts with BEB spots on `V-14 Glory' at boxing, unboxing, 7 and 14 days were 1, 3, 6, and 10, respectively. Weekly Ca sprays (400 ppm at start of color) reduced or prevented BEB in the greenhouse at all locations where BEB developed and reduced the development in BEB during postproduction. BEB increased with fertilizer level and was higher in plants with elevated potassium or ammonium. These effects were reversed by Ca sprays. BEB was increased by boxing wet plants or inoculating plants with Botrytis. BEB was reduced by boxing dry plants, fungicide treatment, or terminating fertilization. BEB symptoms for different cultivars will be presented.

Abstract:
Bract edge burn (BEB) starts as a necrosis on veins near the margins of mature bracts. Typically, BEB first appears at anthesis and symptoms progress over time. In 1993, the incidence of BEB on plants sprayed with sodium silicate (Na2SiO3)—490 ppm Si at weekly intervals during bract development—was compared to unsprayed controls using the cultivar Supjibi. BEB appeared soon after anthesis on unsprayed plants, and, by 309 days post-anthesis, 11.5% of the bracts on unsprayed plants had BEB, but only 0.4% of the bracts on Na2SiO3-treated plants had symptoms. Calcium levels in bract margins were similar (0.194% in both treatments. In 1994, the following spray treatments were applied weekly from 31 Oct. to 5 Dec. (initial anthesis) to the cultivars Supjibi and V-17 Angelika White: CaCl2 (400 ppm Ca), Na2SiO3 (50, 100, 150, or 200 ppm Si), DI H2O (sprayed control), or unsprayed control. Both cultivars developed similar BEB symptoms and responded similarly to all treatments. One week post-anthesis, 5.7% of the bracts on unsprayed plants (averaged for both cultivars) developed BEB and 2.5% of the bracts on sprayed controls developed BEB, but only 0.19% of the bracts on CaCl2- or Na2SiO3-treated plants developed BEB symptoms. By 5 weeks post-anthesis, the incidence of BEB was similar for plants sprayed with CaCl2 and Na2SiO3 at 100, 150, or 200 ppm (1.1%, 6%, 6.7%, and 5.7%, respectively); but higher on sprayed controls (22%), and still higher on unsprayed plants (28.5%).

Abstract:
在香港國際學校,相較于本地學校,更加激烈的崗位競爭、英語為工作語言的整體環境以及背景多樣化的學生等因素是否會導致教師們對職業的認同感和成就感有所不同呢?瞭解國際學校中文教師職業倦怠的情況對教師的個人職業發展、教學工作的有效開展和學校的教師管理都具有重要意義。 本研究旨在對香港國際學校中文教師職業倦怠的情況進行調查,通過Maslash(MBI-ES)問卷,分三個維度(情緒衰竭、非個性化、低成就感)對中文教師職業倦怠的程度進行描述;其次,利用訪談對倦怠的原因和影響因素進行探討和分析。 本次調查採取方便取樣的原則,隨機抽取國際學校中文教師30 人進行調查,利用SPSS17.0 對數據進行整理和分析,組間的差異性采用方差分析(單因素ANOVA)和t 檢驗,人口學特征和職業倦怠各維度的關系采用線性回歸進行分析。 研究發現,香港國際學校的中文教師在情緒衰竭和去個性化兩個維度上表現出中度倦怠,而在低成就感上得分較高,即有較高的成就感體驗。不同性別的教師在倦怠程度上無差異; 不同年齡的教師在低成就感維度上差異顯著( P=0.000),本次調查中,20-30 歲的教師成就感最低,50 歲或以上的教師最有成就感;從入職時間上看,有1-2 年工作經驗的教師有相對高的情感衰竭情況(22.00±6.06);不同入職時間的教師在成就感上差異顯著(P= 0.018),從事對外漢語教學工作3 年或以下的教師成就感低於有3 年以上工作經驗的教師。此外,學歷與成就感表現出顯著相關(B=3.195,P=0.034),學歷越高在教學上的成就感體驗也就越高;同時,香港以外的教學經驗與成就感呈現顯著相關( B=2.253,P=0.05),即教學經驗豐富的教師擁有相對高的成就感。 This study assessed teachers' burnout from different genders, ages, working years, educational levels, working hours and working experience in a sample of 30 Chinese in-service teachers in Hong Kong International Schools by MBI-ES questionnaire and interviews and draw conclusions as follows: The general findings suggested that on the burnout components, indicating moderate levels of emotional exhaustion and depersonalisation, but high or nearly high levels of reduced personal accomplishment. Teachers' reduced personal accomplishment is significant in age( P= 0.000 ) and working years( P= 0.018): teachers of 20-30 years old have the highest scores in reduced personal accomplishment and teachers of 50 years old or above have the lowest scores; teachers with less 3 years working experience have the highest scores in reduced personal accomplishment. What's more, overseas teaching experience and educational levels are highly relevant with reduced personal accomplishment.

Abstract:
Internationally, burns stemming from Juvenile Fire Setting and Bomb Making (JFSB) represent a major healthcare problem as signaled by traumatic deaths and injuries sustained by youth involved in these unfortunate incidents. While JFSB incidents may occur with greater frequency in non-rural locales, emerging evidence shows that the clinical forensic issues secondary to these burn cases can be surprisingly more complex in rural settings. The treatment challenges that rural areas have are fueled by a limited availability of mental health emergency resources. Further compounding it, the treatment professionals accessible to families often have insufficient experience or qualifications for competently managing the traumatic issues presented by combined JFSB/Burn Survivor (BS-JFSB) cases. This chapter aims to demonstrate how trauma-focused approaches can be integrated into existing clinical forensic practices in rural settings. The treatment requires altering how the concerns presented by these BS-JFSB children are addressed within a risk assessment paradigm.

Abstract:
The earliest archaeology of the hagiographical dragon fight is investigated through the lens of a remarkable pagan parody of the story-type roughly contemporary with the earliest extant example of it, this parody being found in Lucian’s Philopseudes or Lover of Lies of around the AD 170s. The parody indirectly attests the prior existence of a number of motifs in the tradition not actually documented within it until some centuries later. Consideration is given to its allusions to the Gospels and to its proto-hagiographical motifs of: the serpent-brood presided over by an ancient drakōn; the last victim boy; the blowing upon the dragon to burn it; the magical healing of a workman’s snakebite; and the use of material from the tomb of a holy person.

Abstract:
Several sites containing relatively high quantities of waste products from the bloomery iron production collected during archaeological field surveys in the Podravina region as part of the TransFER project were subsequently investigated by magnetic prospecting and topsoil apparent magnetic susceptibility mapping. The magnetic method proved to be very effective in identifying various archaeological remains of iron production activity in situ due to the high magnetic susceptibility of materials present in iron production workshops, which was confirmed in relation to the results of archaeological excavations at Sušine near Virje as well as Velike Hlebine and Dedanovice near the Hlebine sites. Reasons for the higher magnetic susceptibility include, in addition to the strongly magnetic minerals in iron production waste, fragments of fired clay from furnace construction and features such as shallow pits with burnt bottoms, as well as any other materials that have been exposed to high temperatures (burnt house plaster, etc.). The sites with remains of bloomery iron production were therefore reliably identified on the basis of their magnetic properties and the results were evaluated in relation to the excavated features. This study has also demonstrated that the sites with iron production activity present can also be reliably identified on the basis of changes in the apparent magnetic susceptibility of the topsoil to a depth of only 5 cm, after partial destruction of the archaeological layers by deep ploughing. These anomalies generally have a wider spatial distribution than those detected by magnetometers, due to a wide dispersion of material by ploughing mechanisms. With the aim of identifying layers with major enrichments of bog iron ore, electrical resistivity tomography (ERT) measurements were carried out at the site Novigrad Podravski–Milakov Berek, where pieces of bog iron ore appeared on the surface. Based on these results, we have not been able to reliably identify ore deposits, but it has been shown that it is possible to identify layers of relatively low resistivity on ERT profiles that have increased iron mineral content, as confirmed by X-ray analysis of core samples from shallow drillings at several other locations in the Podravina region.

Abstract:
About ten miles north of where I live in northern Colorado, a smokestack rises 500 feet in the air alongside a stair-step series of buildings. On a summer day, nothing appears to be coming from the smokestack, as though it is a ghostly relic; in the winter, a white plume rises. On closer approach, a lake teeming with ducks, geese, pelicans, and other waterfowl sits in the foreground. A herd of American bison roam on over 4,000 acres of grasslands surrounding the smokestack. This apparently benign plant called Rawhide Energy Station is actually a 280 MWe coal-fired power plant that provides about one-quarter of the electricity for four nearby communities—Fort Collins, Loveland, Longmont, and Estes Park. It is a public utility owned by the four communities and is near state-of-the-art for a coal-fired power plant, being one of the most efficient in the western United States and among the top ten in lowest emissions. I drove up to the Rawhide Energy Station and called on an intercom box to the security station to identify myself so the guard could open the security gate for me to enter. After driving across the edge of the lake, the armed guard then directed me to the visitor center. I met Jon Little, the knowledgeable and friendly tour guide, and a group of bicyclists from a local environmentally conscious brewery who were taking the tour also. We put on headphones with a radio set and a hard hat for the tour. The first and largest building houses the boiler and the generators. Th e coal arrives by train in five- to six-inch lumps, which are broken down into one-inch lumps before being fed by conveyor to grinders that convert it into a powder finer than facial powder. This powder is then mixed with air and blown into the 16-story. boiler from four directions, where it burns efficiently at a hellish temperature of 2,800˚F.

Abstract:
Making mistakes in the spiritual life is an essential part of growth—as important as forest fires, blow-downs, and insects are to the life of a thriving forest. You grow only in being burnt, bent, and bitten. You have to stumble before you can walk. My error this time wasn’t intentional. I saw no signs at the trailhead and didn’t think to ask. I simply hauled my backpack up Laramie Peak in the Medicine Bow Wilderness of eastern Wyoming, planning to spend the night somewhere near the top. Only later did I learn that camping isn’t allowed anywhere on the mountain. Sometimes ignorance is bliss. More often it’s simply dangerous. Yet I had the mountain to myself that night, or I should say that it had me. I was new to backpacking at the time. But I don’t remember ever being so overwhelmed by deep silence and a haunting sense of presence as I was that night at 10,000 feet near the mountain’s peak. Fallen limbs, rock outcroppings, and thick ground cover made it impossible to venture very far off the trail. It was hard even to find a semi-flat piece of ground to sleep on in the dense, moss covered undergrowth. Everything resisted my being there. Still more disturbing was the feeling that I was being watched—studied from beyond the shadows by something I couldn’t see. I’ve seldom felt so ill at ease in wilderness. Something was out there, frightening in its apparent indifference to my well-being. Laramie Peak stands alone on the easternmost edge of the Rocky Mountains. At 10,272 feet, it is smaller than the Colorado fourteeners to the southwest. But it offers an imposing silhouette, jutting up from the northern plains like Mt. Fuji rising above the mountains west of Tokyo. One can see it for miles along Highway I-25 in eastern Wyoming. Nineteenth-century settlers on the Oregon Trail caught sight of it from Scotts Bluff in the Nebraska Territory, 120 miles to the east. It was their first warning of the foreboding mountains that lay ahead.

Abstract:
The voices of staff members are important to any school improvement process. The perceptions of those who work in a school can have a significant impact on the environment within that school. Improving school climate doesn’t mean only making sure that stu­dents feel safe and welcome and believe that adults care about their academic and social-emotional well- being. It also means that teachers, administrators, and other school staff feel committed to the school, view it as a good place to work, and believe they have a role in promoting positive experiences for all students— even those not in their classes or otherwise assigned to them. Staff surveys are an important part of a comprehensive monitoring system because they can tell us first- hand about the lives of staff members in school and can also add another perspective on student behaviors. Staff members are an essential source of information on the interrelationships among teachers, administrators, and classified personnel. For teachers and supporting staff members to contribute best to school performance, they need to feel that the organizational climate supports them and their work. Teachers who feel unappreciated and that they operate under difficult working conditions will be less motivated to invest in their work and may burn out faster and leave the school. Such frequent staff turnover has disastrous consequences for students’ lives in school (see Box 6.1). Staff members may feel that asking for students’ perceptions of how they teach and run the school puts them in a disadvantageous position in which others can blame them for academic or behavior problems among students. Listening to staff members and their views of the students, the school, and the district leadership is a way of communicating that their opinions and perceptions are valued. It is also a way for leaders to advocate for the importance of listening to feedback and to show that they welcome feedback from staff members about their performance. Providing regular opportunities for feedback from staff members is an important way to assess their needs for training and other types of support.

Abstract:
When moving towards CO2 neutral bio fuels and waste derived fuels, new challenges are set for combustion facilities and technical boiler solutions. A common feature for both bio- and waste fuels is a big variety in composition, often high levels of alkali metals, chlorine and moisture which make these fuels difficult to burn in facilities designed for conventional fuels such as coal, peat and wood. The problems that might occur due to high alkali and chlorine levels in the fuels, are slagging, fouling, corrosion and bed sintering. The Fortum BioMAC BFB boilers are designed especially for difficult, unconventional fuels such as rice husk, olive waste, straw, construction residue, de-inking sludge, etc. The design of each individual boiler is made based on advanced theoretical prediction tools and extensive fuel testing in laboratory and in pilot scale combustion facilities. The theoretical tools consist of a multi-phase multi-component chemical equilibrium model that estimates the slagging/fouling, sintering and corrosion propensity of the fuels/fuel mixtures and of a computational fluid dynamics part. CFD calculations are used to optimize the flow pattern and the temperature of the boiler in order to avoid hot temperatures in the vicinity of refractory linings and cooled surfaces. The chemical equilibrium calculations predict the melting behavior of the fuel ash, which is used as an indicator for the placement of the superheaters. The bottom ash removal is controlled for efficient removal of coarse material, screening and recirculation. The ash related problems of important bio and waste fuels, the analytical procedure of the evaluation of the usability of the fuels and the adaptation of the boiler design are discussed in the paper.

Abstract:
Fuels currently used for energy production in thermal power plants are characterized by their huge variety ranging from fossil fuels to biomass and waste. This multitude of fuels offers opportunities to the energy industry and nowadays many power plants do not fire either of these fuels but mixtures of them are burnt. While this procedure may lead to overall economic and environmental advantages it is very demanding for the boiler operators to still meet expectations concerning boiler performance, boiler availability and emission regulations. In the course of this latest trend in boiler operation, ash related operational problems such as slagging, fouling and corrosion are ranking very high on the list of reasons leading to significant reduction of boiler availability. Ash related problems strongly dependent on fuel specific aspects, such as the mineral matter distribution in the fuel, aspects specific to the used combustion technique as well as design aspects unique for the combustion chamber of any operating power plant. The overall goal in combustion related research is therefore the prediction of potential operational problems originating from fuel streams entering the combustion chamber as well as those originating from the design of individual furnaces. In our earlier work we have strongly focused on developing an advanced ash behavior prediction tool for biomass combustion combining computational fluid dynamic calculations (CFD) and advanced fuel analysis. In this paper the tool is applied to analyze the slagging and fouling tendency in a 295 MW bubbling fluidized bed boiler fired with mixtures of peat and forest residue. In addition to the overall deposition prediction this work focuses on details of the models used in the computational fluid dynamic calculations. These include a study on the importance of the accurate description of the fuel feeding system and related to this aspect the advanced description of the bubbling bed with regard to release of primary gas and ash particles from its surface to the freeboard. Evaluation of the predictions comparing simulation results with deposits on the furnace walls show good agreement.

Abstract:
Biofuels such as ethanol have lower energy density than conventional petroleum-based fuels, and therefore enhancing its energy density via addition of high-energy density components is an attractive option. Boron is an attractive fuel additive because it has among the highest volumetric heating value among potentially suitable additives. The present study deals with an experimental investigation of boron combustion in an ethanol spray flame. A constant low particle loading density of boron nanoparticles (60nm SMD), around 1% (by weight) of the liquid fuel flow rate, has been used. Though it has high energetic potential, the combustion process of boron is retarded by the initial presence of the oxide coating the particle surface. In the present study, measurements have been made of the emission of intermediate sub-oxide like BO2 using spectroscopy and imaging with interference filters. The effect of boron on the hydrocarbon combustion has also been studied by examining the heat release and product mole fractions. In addition, particle characterization has been carried out to know the size, surface structure/composition of the injected boron nano powders using XRD, XPS and TEM. A preliminary investigation has also been performed on the burnt particle collected from the exhaust structure using XRD. The chemiluminescence and spectroscopic signatures indicate that boron combustion is facilitated and that hydrocarbon combustion is enhanced. The particle analysis shows differences in the imaged and spectroscopic characteristics of the unburnt and burnt nano-particles reflecting the particle-combustion processes.

Full text
Abstract:
This article describes a study involving new spark plug technology, referred to as pulsed energy spark plug, for use in igniting fuel-air mixtures in a spark ignition internal combustion engine. The study involves precisely controlled constant volume combustion bomb tests. The major defining difference between the pulsed energy spark plug and a conventional spark plug is a peaking capacitor that improves the electrical-to-plasma energy transfer efficiency from a conventional plug’s 1% to the pulsed energy plug’s 50%. Such an increase in transfer efficiency is believed to improve spark energy and subsequently the ignition time and burn rate of a homogeneous, or potentially stratified, fuel-air mixture. The study observes the pulsed energy plug to shorten the ignition delay of both stoichiometric and lean mixtures (with equivalence ratio of 0.8), relative to a conventional spark plug, without increasing the burn rate. Additionally, the pulsed energy plug demonstrates a decreased lean flammability limit that is about 14% lower (0.76 for conventional plug and 0.65 for pulsed energy plug) than that of the conventional spark plug. These features — advanced ignition of stoichiometric and lean mixtures and decreased lean flammability limits — might qualify the pulsed energy plugs as an enabling technology to effect the mainstream deployment of advanced, ultra-clean and ultra-efficient, spark ignition internal combustion engines. For example, the pulsed energy plug may improve ignition of stratified-GDI engines. Further, the pulsed energy plug technology may improve the attainability of lean-burn homogeneous charge compression ignition combustion by improving the capabilities of spark-assist. Finally, the pulsed energy plug could improve natural gas spark ignition engine development by improving the ignition system. Future work could center efforts on evaluating this spark plug technology in the context of advanced internal combustion engines, to transition the state of the art to the next level.

Abstract:
Biomass, a renewable fuel source for generating energy, is available in large quantities in the USA. Typical biomass consists of wood chips, construction and demolition wood, bark, residual logging debris, saw dust, paper rejects, and paper and sewage sludge. Composition and moisture content of biomass vary greatly and affect its heating value. There are several combustion technologies available to generate power from biomass. Fluidized bed boilers are preferred, because of their ability to burn a wide variety of biomass fuels while achieving high combustion efficiency and low emissions. This paper discusses basic design and operation features of bubbling (BFB) and circulating fluidized bed (CFB) boilers, both offering high fuel flexibility. In fluidized bed combustion, reactive biomass fuels are almost completely burned out because of close contact between the hot bed material and the fuel. In advanced BFB and CFB boilers, an open bottom design is used for ash and coarse material removal through the fluidizing air distribution system. This allows combustion of fuels containing large inert particles, such as rocks and metal pieces. If limestone is added to the bed, SO2 emissions are reduced. By using ammonia or urea in high temperature areas, NOx emissions are reduced. In order to achieve very low emissions, back-end flue gas treatment for SO2, NOx, HCl, HF, and Hg is required. To treat flue gases, several technologies can be used — such as activated carbon and sodium bicarbonate or Trona injection, Turbosorp® circulating dry scrubber, and SCR. Normally the preferred particulate matter cleaning device is a baghouse since the filter cake allows further reactions between pollutants and sorbents. Different fluidized bed designs are shown and recommended for various biomass fuels. This paper describes design, fuels, and emissions for an advanced BFB boiler producing steam at a rate of 230,000 lb/hr/930 psig/860°F (29.0 kg/s/64 barg/460°C).

Abstract:
It is a very challenging problem to reliably ignite extremely lean mixtures, especially for the low speed, high load conditions of stationary large-bore natural gas engines. If these engines are to be used for the distributed power generation market, it will require operation with higher boost pressures and even leaner mixtures. Both place greater demands on the ignition system. The railplug is a very promising ignition system for lean burn natural gas engines with its high-energy deposition and high velocity plasma jet. High-speed photography was used to study the discharge process. A heat transfer model is proposed to aid the railplug design. A parameter study was performed both in a constant volume bomb and in an operating natural gas engine to improve and optimize the railplug designs. The engine test results show that the newly designed railplugs can ensure the ignition of very lean natural gas mixtures and extend the lean stability limit significantly. The new railplug designs also improve durability.
