Abstract:

Abstract Fall and spring prescribed fires were conducted in two Pennsylvania sugarbushes to evaluate the effects of fire on the emergence of overwintering pear thrips from the soil. Soil temperatures and numbers of emerging pear thrips were monitored in the burned and unburned areas at 2-day intervals from mid-March until early May 1991. At both sites, fall fires accelerated soil warming, resulting in an earlier peak emergence of the thrips. The fall and spring fires also significantly reduced the number of thrips emerging from the soil. These results suggest the potential for controlling pear thrips infestations in sugarbushes with prescribed fire, although fire impacts on sugar maple need to be addressed before this technique can be widely recommended.

Abstract:

The relationship between budburst phenology and damage by the pear thrips (Taeniothripsinconsequens (Uzel) (Thysanoptera: Thripidae)) to sugar maple (Acersaccharum Marsh.) foliage was investigated in two studies. In the first study, seedlings in cages were exposed to adult thrips at different stages of budburst. Compared with uninfested control seedlings, introduction of five adult thrips per bud reduced total leaf area and average leaf size, and caused chlorosis, tattering, and cupping of leaves. Leaf area reduction and damage symptoms were greater for seedlings exposed to thrips when leaf margins were first visible at the tip of the bud compared with earlier and later stages of budburst. In the second study, budburst date and number of thrips oviposition sites on leaves (an index of thrips activity) were measured in a common-garden test of maple saplings from open-pollinated families. Thrips activity was greater on early-breaking than late-breaking buds. Date of opening for these early-breaking buds coincided closely with peak capture of flying thrips. Both budburst date and number of oviposition sites on leaves differed among families. Sugar maple genotypes with late budburst escaped heavy thrips damage. The results indicate that timing of vegetative budburst in sugar maple can influence the degree of thrips damage.

Abstract:

AbstractWidespread defoliation of sugar maple stands due to pear thrips, Taeniothrips inconsequens (Uzel), feeding occurred in Massachusetts in 1987 and 1988. To assess the role of tree health as a possible cause of these outbreaks, an experiment was conducted in sugar maple stands in Massachusetts in 1990. Sleeve cages were placed on mature sugar maples and stocked with adult female pear thrips to determine the relation between root starch reserves (an index of tree health) and thrips fecundity. The experiment was run at four sites, assessing both root starch levels and thrips fecundity on individual trees. Each stand showed a range from high to low starch values and trees at each end of the root starch index spectrum were selected for use in the experiment at each site. Analysis of data showed no differences between sites, apart from those linked to starch levels, and found thrips fecundity to be positively correlated with higher starch reserves. The results of this experiment do not support the original hypothesis that declining tree health was a causal factor in pear thrips outbreaks on sugar maple in Massachusetts.

Abstract:

Sugar maple (Acersaccharum Marsh.) seedlings were exposed to either cool (11.9 °C) or warm (18.2 °C) temperatures in the presence or absence of adult pear thrips (Taeniothripsinconsequens Uzel) during bud burst and early spring growth. Time required for spring stem elongation was shorter at the warm temperature than at the cool temperature. Thrips feeding reduced height, leaf area, and seedling dry weight at both temperatures, and reductions were greater at the cool temperature than at the warm temperature. The results indicate that cool temperatures that slow bud burst promote pear thrips damage to sugar maple leaves.

Abstract:

Recent damage to sugar maple, Acer saccharurn Marsh., by pear thnps, Taeniothrips inconsequens, in the northeast of the United States and adjacent parts of Canada has led to much research on this pest (Teulon et al. 1993; Teulon and Cameron 1996; Parker and Skinner 1997). A detailed description of the univoltine pear thrips' life history is reported in Teulon et al. (1998). Although T: inconsequens is the dominant species in sugar maple, other thrips may also be important as herbivores, detritivores, or predators and need to be taken into account in sampling or monitoring programmes. This article describes the diversity of thrips in a sugar maple plantation in central Pennsylvania, United States.

Abstract:

In field experiences studies on growing field peas in single-component and mixed seeding with spring rape and white mustard were conducted in the Middle Urals. The crop capacity was increased by 10,8% as well as the total yield was increased by 2.3 times up to 2.14 t / ha by the use of spring rape as a supporting and compacting crop in sowng peas with a seeding rate at 0.6 million / ha. It was found out that crop productivity of peas was decreased by 19.4% when the seeding rate was established at 0.4 million / ha, and the crop productivity of spring rape remained at the level of pure sowing – 1.23 t / ha. The total yield, in comparison with the pure sowing of peas, increased by 2.1 times from 0.93 to 1.98 t / ha. Mustard is less suitable as a supporting crop, although it ripes earlier and does not thrive in contrast to spring rape. The total yield and ratio of land equivalents in a mixture with spring rape is higher than with mustard and ranged from 1.66 to 1.98. Peas accounts for the bulk of the total yield (LERab = 0.81...1.48). The coefficients of competitiveness and aggressiveness of the studied crops in mixed sowing indicate the dominant role of field peas in the pea-rape and pea-mustard agrocenoses. The awned and foliose morphotype of field peas when grown in a mixture with mustard showed themselves equally, their competitiveness and aggressiveness coefficients were in a close range – Crab = 2.37...4.57; CAab = 0.72...1.87. The awned morphotype of field peas had the greatest aggressiveness and competitiveness when cultivated in a mixture with spring rape – CRab=6.78...17.80; CAab = 3.35...5.79. The foliose morphotype of field peas occupied an intermediate position and had a good competitive ability with less aggressiveness towards spring rape – Crab = 2.64...2.66; CAab = 2.06...2.13.

Abstract:

Abstract The operator relentlessly thrives for the minimum well construction cost. Continuous improvement and Innovative approach are the major drives for developing the marginal gas field, Myanmar offshore. Whereas, routine and consistent operations may mask up the operator and leave out many rooms for improvement from operation excellence during the development phase of the project life cycle. PTTEPI successfully started up the second development campaign, Myanmar offshore in early 2016. Since then the team has brought up many ideas to continuously improve the operation and achieve milestones for both safety and performance. This paper will share the best in class for well construction of Myanmar offshore on well design, drilling engineering, rig selection, offline utilization, drilling and sand control practices and fit for purpose procedures. The performance is significantly improved on both drilling and sand control operation which results in total days per well reduction over 50% and 80% for drilling operation and sand control operation respectively. Total days per well for drilling performance on the last platform in 2019 is reduced to 4 days per well compared to 9 days per well when the first development platform was drilled in 2013. Sand Control performance is improved further. Total days per well for Sand Control performance on the last platform in 2019 is reduced to 3.5 days per well (dual-zone completion) compared to 18 days per well when the first development platform was completed in 2013. Recommended practices and well designs are shared as a case study of drilling and sand control operation for Myanmar offshore development. This can be a guideline for another operator to develop oil and gas field offshore Myanmar.

Abstract:

To survive and thrive in the challenging context of the 21st century, education must keep abreast of global trends, including the priority of developing in learners the capability of lifelong learning for enhanced cooperation, care, reflective abilities, critical capacities and creativity. As a potential approach to achieve this goal, Computer Supported Collaborative Learning (CSCL) is receiving increasing attention, as it revolutionizes the way of learning. The ultimate success of CSCL, however, often depends upon resolving the question of how it can be assessed in ways that are credible and reliable and how the technology-driven environment can enhance learning. Little guidance is found in the literature on the assessment of CSCL prompts the researcher to re-examine the role of assessment in learning and attempt to devise a peer assessment design in a technology-enhanced environment as part of the learning activities for full-time teacher-educators. In the three studies of this project, the creation of assessment rubrics, the submission of intra-group reflective journals, which formed the basis of the group’s growth (learning process), and the intergroup review, which gained from peers’ feedback to their project presentation and report (learning product) were incorporated as the assessment measures. It was encouraging to witness that learners of the same cohort had improved their lifelong learning skills progressively over the period of three years by engaging in peer assessment tasks. The findings of these studies indicated that skills fostered through peer assessment were highly relevant to their workplace as teachers when teamwork, interpersonal skills and the ability of self-reflection were emphasised. This study has demonstrated some good practice that supports student-centered learning, prepares students to be lifelong learners and which is suitable for adaption to suit other contexts.

Abstract:

Three consecutive randomized open studies have been carried out in 892 patients undergoing abdominal, gynecological, thoracic or urological surgery. They were over 40 years old and presented at least one of the following risk factors for thrombosis: previous thromboembolism, obesity, varicose veins, malignancy (30% in these studies), pre-operative hospitalization over 5 days, estrogen therapy, chronic cardiac disease or bronchitis. The two groups of each trial were well matched with regard to population characteristics. The third trial included higher rate of patients undergoing urologic surgery. Isotopic venous thromboses and bleeding complications were assessed after subcutaneous administration of a low molecular weight (LMW) heparin fragment (Enoxaparin, 1 mg = 100 Anti-Xa I.U.) or unfractionated heparin (UH). The 3 studies compared 3 × 5,000 IU UH daily with 1 × 60 mg, 1 × 40 mg, or 1 × 20 mg LMW heparin daily. Thromboembolic event rates were not significantly different among the groups (UH : 3.6, 2.8, 7.6% respectively compared to LMWH : 3, 2.8, 3.7%). Significant decrease of hematocrit and hemoglobin were only observed in patients receiving 60 mg Enoxaparin (as compared to UH) whilst in the 2 other trials no difference could be evidenced between the 2 populations. The metaanalysis of the three studies on the “intention to treat” patients gave results consistent with those observed in good compliers. The three consecutive studies showed homogeneous results (p = 0.20), the Mantel Haenszel test did not evidence a global difference between Enoxaparin and unfractionated Heparin (p = 0.54). These results suggest that an optimal dosage of 20 mg per day of Enoxaparin is safe and as efficient as UH 5,000 IU × 3 in the prevention of post-operative thrombosis in this population.

Abstract:

Due to increased energy demand and thrive for clean energy, offshore wind energy has become popular these days. A large number of offshore wind turbines supported by fixed type substructures have been installed, among which jacket structures are getting popular in recent times. The forces from breaking waves are a major concern in the design of offshore structures installed in shallow waters. However, there are only limited studies available regarding breaking wave forces on jacket structures and still there exist many uncertainties in this area. During the WaveSlam experiment carried out in 2013, a jacket structure of 1:8 scale was tested on a large number of breaking wave conditions. Wave properties and the forces on the structure were measured during the experiment. The total wave slamming forces are being filtered from the experimental measured force using the Empirical Mode Decomposition method and local slamming forces are obtained by the Frequency Response Function method. Based on these results, the peak slamming force and slamming coefficients on the jacket members are estimated. The wave parameters (wave height and period) and wave front asymmetry are obtained from measured wave properties. The variation of slamming forces and slamming coefficients with respect to these parameters are also investigated.

Abstract:

Flappy Bird is a mobile game that involves tapping the screen to navigate a bird through a gap between pairs of vertical pipes. When the bird passes through the gap, the score increments by one and the game ends when the bird hits the floor or a pipe. Surprisingly, Flappy Bird is a very difficult game and scores in single digits are not uncommon even after extensive practice. In this paper, we create three controllers to play the game autonomously. The controllers are: (1) a manually tuned controller that flaps the bird based on a vertical set point condition; (2) an optimization-based controller that plans and executes an optimal path between consecutive tubes; (3) a model-based predictive controller (MPC). Our results showed that on average, the optimization-based controller scored highest, followed closely by the MPC, while the manually tuned controller scored the least. A key insight was that choosing a planning horizon slightly beyond consecutive tubes was critical for achieving high scores. The average computation time per iteration for the MPC was half that of optimization-based controller but the worst case time (maximum time) per iteration for the MPC was thrice that of optimization-based controller. The success of the optimization-based controller was due to the intuitive tuning of the terminal position and velocity constraints while for the MPC the important parameters were the prediction and control horizon. The MPC was straightforward to tune compared to the other two controllers. Our conclusion is that MPC provides the best compromise between performance and computation speed without requiring elaborate tuning.

Abstract:

Thin-walled beams with open-section are extensively employed as energy absorption structures in transportation system, e.g., automobile bumper beams and guardrails. However, during the crushing process of these traditional open-section structures, local section flattening and lateral buckling of the webs always occur, which lead to a reduction on section-height, resulting in a significantly smaller bending resistance at the later stage of deformation and the formation of localized plastic hinges. This paper presents a novel design of high performance energy absorption beams using developable origami patterns. The origami beams overcome the problems associated with traditional open-section structures and they give nearly constant bending resistance during crushing process. Numerical analysis shows that the specific energy absorption (energy absorption per unit mass) of the origami beam is at least 20% higher in large deformation than that of the traditional thrie-beam which often used as guardrail. Our research finding demonstrates that utilising origami patterns to open-section beams can effectively alter their collapse modes, attain nearly constant bending resistance and achieve higher specific energy absorption.

Abstract:

Concerns over rising fuel prices, national security, and the environment have led to the Energy Independence and Security Act (EISA) of 2007, which established a mandate for the production of at least 36 billion gallons of biofuels in 2022, up to 15 billion gallons of which can come from traditional first-generation biofuels sources such as corn starch-based ethanol. One consequence of ramped-up biofuels production is the risk of additional soil runoff. This runoff, potentially laden with nitrogen and phosphorus compounds from fertilizers, can detrimentally impact water quality. Consequently, the water treatment sector might require additional energy to remove increased quantities of sediment and run-off from nutrients and pesticides in degraded water bodies downstream of agricultural land. At the same time, the cumulative effects of increased eutrophication in the Mississippi and Atchafalaya River Basins have already negatively impacted much of the aquatic life in the Louisiana-Texas continental shelf. A recent report by U.S. Geological Survey measured nitrogen loading in the Mississippi River basin as high as 7,761 metric tons per day, the highest recorded loading in the past three decades, 52% of which is attributed to loading from corn and soybean crops. Massive algae blooms that thrive in nutrient-rich water deplete the water of oxygen when they die, creating a hypoxic region. This hypoxic region, which currently covers a region the size of New Jersey, is considered to be the second-largest dead zone in the world as of 2007. As a result, the Gulf Hypoxia Action Plan of 2008 was established to reduce nitrogen and phosphorous loading by 45% in order to shrink the hypoxic region to 5,000 square kilometers. Thus, at a time when water quality priorities aim to decrease nitrogen and phosphorous loading in waterways, legislative targets are seeking to increase corn starch-based ethanol production to 15 billion gallons a year, and thereby potentially increase nitrogen loading in this region by 10–34% due to runoff. Consequently, the energy intensity for water treatment may have a two-fold challenge. Because water and wastewater treatment is already responsible for 4% of the nation’s electricity consumption, putting more stringent demands on this sector could put upward pressure on energy consumption. This analysis quantifies the impact that the mandated increase in ethanol production might have on the energy required for water treatment in the United States. It reports results from a first-order top-level analysis of the energy impacts of ethanol. The results indicate that the increased production corn-starch based ethanol in the United States is not likely to increase the energy consumed during surface water treatment, but might cause significant increases in the energy consumed during groundwater treatment.
