Full textAbstract:
Reduced lung volumes and atelectasis are common after open-heart surgery, and pronounced restrictive lung volume impairment has been found. The aim of this study was to investigate factors influencing lung volumes on the second postoperative day. Open-heart surgery patients (n=107, 68 yrs, 80% male) performed spirometry both before surgery and on the second postoperative day. The factors influencing postoperative lung volumes and decrease in lung volumes were investigated with univariate and multivariate analyses. Associations between pain (measured by numeric rating scale) and decrease in postoperative lung volumes were calculated with Spearman rank correlation test. Lung volumes decreased by 50% and were less than 40% of the predictive values postoperatively. Patients with BMI >25had lower postoperative inspiratory capacity (IC) (33±14% pred.) than normal-weight patients (39±15% pred.), (P=0.04). More pain during mobilisation was associated with higher decreases in postoperative lung volumes (VC:r=0.33,P=0.001; FEV1:r=0.35,P≤0.0001; IC:r=0.25,P=0.01). Patients with high BMI are a risk group for decreased postoperative lung volumes and should therefore receive extra attention during postoperative care. As pain is related to a larger decrease in postoperative lung volumes, optimal pain relief for the patients should be identified.

Full textAbstract:
The effect of pressure, solids concentration and volume of slurry on total and two-phase filtrate volumes was investigated to establish optimum conditions for routine laboratory filtration. Full factorial design with three levels was utilized to obtain 27 unique experiments. The slurry used was prepared by mixing crushed and sieved bentonite clay of 75 microns with distilled water at different concentrations as obtained from the design of experiment. A filter press was utilized and the results were used to calibrate a two-phase exponential equation for sludge filtration to extract the first and second stage filtrate volumes. The total filtrate volume improved with increasing applied pressure and decreasing solids concentration. A slurry volume of 0.22 litres was found to be ideal. Similar effects were noticed on the first and second stage filtrate volume except that an optimum was discovered at 0.18 litres of slurry. The second stage filtration produced an upward curve with a point of inflection at a range of 0.18 to 0.22 litres of slurry. The second stage filtrate volume is also discovered to be directly proportional to the total filtrate volume. This connection may be considered for use to assess the filterability of other slurries.

Full textAbstract:
These are the first two volumes out of the ten planned by the National Museum in Cracow, which together will constitute the publication of the body of work donated to the museum by Feliks “Manggha” Jasieński. One volume presents the collector’s creative biography and the history of his various collections. There are also attempts to interpret the nature of the content of his collections, mainly woodcuts and other Japanese objects, as well as modern Polish art, paintings, engravings (together with a set of European engravings) and decorative arts. The second volume is the first part of a monumental catalogue of the collection which covers drawings, watercolours and pastels by Polish artists. The subsequent eight volumes are envisaged to cover particular parts of this extensive collection (of Polish, European and Eastern paintings, drawings, sculpture, engravings and decorative arts). This enormous undertaking marks the 100th anniversary of Jasieński’s donation (1920–2020), and, as Zofia Gułubiew put it, is intended to visualise and fix the extent and variety of the collection in the public’s awareness. The publishing project by the National Museum in Cracow is extremely valuable, and it should be hoped that it will succeed as intended.

Full textAbstract:
Abstract Several studies have indicated that forest characteristics can be accurately predicted using airborne laser scanner (ALS) data, but there are very few studies in which species-specific forest characteristics have been estimated. This article compares two approaches for determining species-specific volumes at plot level by combining ALS data with aerial photographs. The first approach consists of two stages: (1) prediction of total volume using ALS data, and (2) assignment of this total volume to tree species by fuzzy classification and aerial photographs, in which three fuzzy classification methods were tested. In the second approach, volumes by tree species and the total volume are predicted simultaneously using a nonparametric k-most similar neighbor (k-MSN) method based on both ALS data and aerial photographs in one phase. The test area, located in Finland, consists of 463 sample plots. Species-specific volumes were estimated for pine, spruce, and the deciduous trees as a species group, total volume being the sum of the species-specific volumes. The k-MSN method produced considerably more accurate estimates for the species-specific volumes than any fuzzy classification method, the relative RMSEs for the volumes of pine, spruce, and deciduous trees being 45.50%, 61.98%, and 92.30%, respectively, and that for the total volume 23.86%.

Full textAbstract:
Background The COVID-19 pandemic disrupted medical care in the US, leading to a significant drop in utilization of some types of health services. We sought to quantify how the pandemic influenced obstetrics and gynecology care at two large health care organizations. Materials and methods Comparing 2020 to 2019, we quantified changes to obstetrics and gynecology care at two large health care organizations in the United States, Allegheny Health Network (in western Pennsylvania) and Johns Hopkins University (in Maryland). The analysis considered the numbers of surgical encounters, in-person visits, and telemedicine visits. For each system, we quantified temporal changes in surgical volume, in-person and telemedicine visits, and financial impact related to professional fee revenues. We used segmented regression to evaluate longitudinal effects. Results At both institutions, the volume of care was similar in the first few months of 2020 compared to 2019 but dropped precipitously in March 2020. From April to June 2020, surgical volumes were 67% of the same period in 2019 at Allegheny Health and 48% of the same period in 2019 at Johns Hopkins. During that same interval, televisits accounted for approximately 21% of all ambulatory care at both institutions. Although surgical and ambulatory volumes recovered in the second half of 2020, annual surgical volumes in 2020 were significantly lower than 2019 at both institutions (p<0.05) and 2020 ambulatory volumes remained significantly lower at Johns Hopkins (p = .0006). Overall, revenues in 2020 were 91% of 2019 revenues for both institutions. Conclusions Obstetrical and gynecologic ambulatory visits and gynecologic surgeries were sharply reduced during the COVID-19 pandemic. Although care volumes returned to 2019 levels in late 2020, we observed an overall reduction in the volume of care provided and a 9% reduction in professional revenue for both institutions.

Full textAbstract:
Oil discharge prevention and contingency plans (ODPCPs) have been required under Alaska statutes and regulations for oil exploration, production, storage, and transportation facilities since 1992. BP Exploration (Alaska) Inc. (BPXA) has prepared and submitted their North Slope ODPCPs (Milne Point, Endicott, Greater Prudhoe Bay, and Northstar) as a single volume for each facility under these requirements. However, in 2011, when the four plans were renewed, BPXA elected to present their ODPCPs in two volumes for each facility. The purpose of this organizational change from one to two volumes was to focus information in each volume; the first volume is a stand-alone Emergency Action Plan for spill responders, dedicated to spill response planning and preparedness, and the second volume is dedicated to spill prevention requirements and procedures. The 2-volume edition allows BPXA's plan writers, operators, and regulators to concentrate on specific response or prevention topics and regulatory compliance. The 2-volume plan is easier to use and revise through the amendment process. This approach is allowed under Alaska regulations and was embraced by the Alaska Department of Environmental Conservation. Federal regulators (Bureau of Safety and Environmental Enforcement, US Environmental Protection Agency, US Coast Guard, and US Department of Transportation) have reviewed and approved the 2-volume response plans as well. According to regulators, with such large ODPCPs, the effort to maintain publication efficiency during public review creates a potential risk of confusion or lack of sufficient detail, which may lead to comments that focus on form or style, rather than content. Working with two volumes circumvented this potential problem. Due to the size and lengthy history of the facilities, an comprehensive Alaska regulations governing the contents of ODPCPs, two volumes allowed BPXA to include all of the necessary information for the plans without creating a storage or ergonomic problem for the reviewers. Regular users of the ODPCPs at the BPXA facilities have found that working with a smaller, more focused volume is more efficient.

Full textAbstract:
In 2011 Prof. Dr. Zoya Mladenova published a major monograph on the state and development of neoclassical theory in the world in the twentieth and early twenty-first century. Her second monograph, on the "paradigm shift" (transition) in economic theory in Bulgaria in the years after 1989, has recently been published. The two editions are thematically linked: the first is about the dominant theory in the world, the second - about the transition to it in Bulgaria. In this sense, both in terms of content and in terms of the author's conception (see p. 13 of the first monograph and pp. 3-4 of the second), the two monographs can be seen as a comprehensive study published in two volumes on issues in the history and state of economic theory in Bulgaria and in the world. There is no similar two-volume edition in the Bulgarian literature.

The books “Indonesian Gastronomy Volumes 1 and 2,” written by Professor Murdijati-Gardjito and colleagues, are interesting because they are among the first gastronomic books authored by experts in Food Science and Technology. While representing a coherent work, the two volumes focus on different aspects. The first one explains aspects of Indonesian culinary history at the national and global levels, including the changes that have taken place in the contemporary era. The second volume pays attention to the technical aspects of physical changes and chemical reactions in the food-making process. Volume 2 also describes Indonesian cuisine based on geographical location and ethnic affiliation.

Full textAbstract:
Purpose: To evaluate the volume of bone cyst using the planimetry method of the Cavalieri principle. Methods: A retrospective analysis was carried out on data from 25 computed tomography (CT) images of patients with bone cyst. The volume of the cysts was calculated by two independent observers using the planimetry method. The procedures were repeated 1 month later by each observer. Results: The overall mean volume of the bone cyst was 29.25 ± 25.86 cm3. The mean bone cyst volumes calculated by the first observer for the first and second sessions were 29.18 ± 26.14 and 29.27 ± 26.19 cm3, respectively. The mean bone cyst volumes calculated by the second observer for the first and second sessions were 29.32 ± 26.36 and 29.23 ± 26.36 cm3, respectively. Statistical analysis showed no difference and high agreement between the first and second measurements of both observers. The Bland–Altman plots showed strong intraobserver and interobserver concordance in the measurement of the bone cyst volume. The mean total time necessary to obtain the cyst volume by the two observers was 5.27 ± 2.30 min. Conclusion: The bone cyst of the patients can be objectively evaluated using the planimetry method of the Cavalieri principle on CT. This method showed high interobserver and intraobserver agreement. This volume measurement can be used to evaluate cyst remodeling, including complete healing and cyst recurrence.

Full textAbstract:
A second 4D seismic monitor survey acquired over the Pluto gas field has been an outstanding success despite three tropical cyclones, the start of a global pandemic, and technical subsurface risks. At the time of the Pluto 4D Monitor Two (M2) survey (December 2019 till February 2020), the Pluto field had been in production for 7 years and 9 months and had produced approximately 2 Tcf of gas. The M2 4D survey was acquired between December 2019 and February 2020 over a 20 × 30 km area, on a 12.5 m square grid. Data was processed by CGG to pre-stack depth migration, took 6 months to deliver, and required considerable collaboration with Woodside geoscientists. Use of modern processing technologies, including least squares migration, full waveform inversion and wave equation based amplitude versus offset inversion facilitated a high quality interpretation. On the 4D difference volumes, hardening responses were interpreted as water ingress. Hardening responses were seen in multiple Triassic reservoirs. A pronounced response was seen in a large Triassic valley within a predominantly mudstone background unit, which showed continued water ingress into the valley, upwards from the gas water contact towards the producing well. This confined hardening response contrasted with unconfined, water flood front responses seen in other reservoirs. Both responses enabled detailed interpretation of geological features and provided useful control points for history matching. Interpreted water ingress also gave additional depth control.

"Can Na18F PET/CT Be Used to Study Bone Remodeling in the Tibia When Patients Are Being Treated with a Taylor Spatial Frame?" Scientific World Journal 2014 (2014): 1–9. http://dx.doi.org/10.1155/2014/249326.
Full textAbstract:
Monitoring and quantifying bone remodeling are of interest, for example, in correction osteotomies, delayed fracture healing pseudarthrosis, bone lengthening, and other instances. Seven patients who had operations to attach an Ilizarov-derived Taylor Spatial Frame to the tibia gave informed consent. Each patient was examined by Na18F PET/CT twice, at approximately six weeks and three months after the operation. A validated software tool was used for the following processing steps. The first and second CT volumes were aligned in 3D and the respective PET volumes were aligned accordingly. In the first PET volume spherical volumes of interest (VOIs) were delineated for the crural fracture and normal bone and transferred to the second PET volume forSUVmaxevaluation. This method potentially provides clinical insight into questions such as, when has the bone remodeling progressed well enough to safely remove the TSF? and when is intervention required, in a timelier manner than current methods? For example, in two patients who completed treatment, theSUVmaxbetween the first and second PET/CT examination decreased by 42% and 13%, respectively. Further studies in a larger patient population are needed to verify these preliminary results by correlating regional Na18F PET measurements to clinical and radiological findings.

Full textAbstract:
We present an analysis of wave energy devices with air-filled compressible submerged volumes, where variability of volume is achieved by means of a horizontal surface free to move up and down relative to the body. An analysis of bodies without power take-off (PTO) systems is first presented to demonstrate the positive effects a compressible volume could have on the body response. Subsequently, two compressible device variations are analysed. In the first variation, the compressible volume is connected to a fixed volume via an air turbine for PTO. In the second variation, a water column separates the compressible volume from another volume, which is fitted with an air turbine open to the atmosphere. Both floating and bottom-fixed, axisymmetric, configurations are considered, and linear analysis is employed throughout. Advantages and disadvantages of each device are examined in detail. Some configurations with displaced volumes less than 2000 m 3 and with constant turbine coefficients are shown to be capable of achieving 80% of the theoretical maximum absorbed power over a wave period range of about 4 s.

New Testament Apocrypha: More Noncanonical Scriptures, edited by Tony Burke and Brent Landau, was published in 2017. It is the first in a series of volumes of apocryphal Christian texts in English translation. This article offers some reflections on the reception of the volume—with a summary of and response to reviews in journals and two panel discussions—and on the process of assembling a second volume to be published in 2020. The article describes the contents of the second volume with particular emphasis on several Johannine apocrypha related to er?tapokriseis (or “question-and-answer” literature) and two texts that may reflect Chistian-Muslim interaction in late antique Egypt. The article concludes with a preliminary list of the texts to be included in a third volume to follow in 2022.

Summary In this article, I propose a different reading of Foucault’s newly published work than suggested by the publishers and in initial reviews. I question the claim that it represents the fourth volume of the History of Sexuality and rather propose to regard it as an intended second volume. Comparing Foucault’s final plan of publication of the series with the background and stated purpose of Les aveux de la chair, I hold that it is part of a different philosophical project than volumes two and three. Foucault wrote Les aveux de la chair to explore the roots of modern power in the experiences that early Christianity occasioned. This makes the work relevant for current theology and the philosophy of religion.

Abstract The two volumes of letters by Mikhail Lifschitz, recently published in Russian, reveal for the first time certain aspects of his relationship with György Lukács and his general intellectual and cultural role in the long history of Soviet aesthetics. The first volume contains all the known letters between Lifschitz and Lukács; the second volume contains the letters from Lifschitz to three of his younger colleagues. Both volumes throw considerable light on the development of Marxist aesthetics in the Soviet Union from the 1930s to the 1980s. The extensive commentaries and notes provide context for the various discussions in the letters and situate the main issues under consideration within the wider historical and social context of the period.

Full textAbstract:
Forty consenting patients took part in a study to determine lobar, segmental and regional lung volumes and flows as reflected by changes in lung radioactivity measured by nuclear medicine techniques. Two hundred MBq of the gaseous radioisotope 133 Xe were injected into a re-breathing circuit spirometer with an 8 litre capacity and an equilibrium activity of 25 MBq/litre. A posterior dynamic acquisition of 400 frames at 0.125 seconds per frame for the determination of lung volumes and flows was completed, followed by a gas washout period. The acquisition recorded both tidal breathing and 3-6 cycles of maximal inhalation and exhalation after homogenous mixing of the radioactive Xenon inside the lungs and the spirometer, but before significant diffusion of the tracer into the blood. The conversion from millilitres to counts was accomplished by matching a representative breath cycle on the spirometric graph with the same cycle on the radioactivity curve generated on the processed scintigram of the whole lung. A change in volume was hence matched to a change in radioactivity, and a specific radioactivity per millilitre of lung volume was calculated. A region of interest was drawn on the scintigram over a lung lobe or segment. The regional radioactivity change represented a regional breath cycle in this area, with regional volume and flow changes. Spirometric parameters such as lobar vital capacity, tidal volume, residual volume and forced expiratory volume after 1 second were derived by using the previously calculated radioactivity per millilitre of lung volume. Total lung volumes and flows derived from radioactivity changes were compared to the concurrent volumes and flows measured on the attached spirometer, and a close correlation was found.

Full textAbstract:
A method for the solution of the three-dimensional structural dynamics equations with large strains using a finite volume technique is presented. The proposed solution procedure is second order accurate in space and employs a second-order accurate dual time-stepping scheme. The momentum conservation equations are written in terms of the Piola-Kirchhoff stresses. The stress tensor is related to the Lagrangian strain tensor through the St. Venant-Kirchhoff constitutive relationship. The structural solver presented is verified through two test cases. The first test case is a three-dimensional cantilever beam subject to a gravitational load that is verified using theory and two-dimensional simulations reported in literature. The second test case is a three-dimensional highly deformable cantilever plate subject to a gravitational load. The results of this case are verified through a comparison with the modal response calculated by commercially available software. The focus of the current effort is the development and verification of the structural dynamics portion of a future fully coupled monolithic fluid-thermal-structure interaction code package.

Full textAbstract:
Following forest harvest, residues left on site are often piled and burned. Quantification of residue piles is required in many jurisdictions to estimate billable waste, harvest efficiency, smoke emissions, C budgets, and available bioenergy biomass. Piled residues and harvested wood were measured on four blocks of a second-growth Douglas-fir forest in coastal British Columbia. Pile wood volumes were determined by two ground-based methods (a Waste and Residue Survey (WRS) and a geometric equation (EEP) used for smoke emissions) and by two geospatial methods using orthophotography (GIS) and LiDAR. Eight sample piles were disassembled to determine plot densities (PD) and packing ratios (PR). Plot density did not differ between the WRS and GIS method. Packing ratios of the EEP were 50% of that of the LiDAR method. LiDAR pile bulk volume and PR were negatively correlated. Choice of LiDAR digital elevation model had no significant effect on pile bulk volumes. The WRS method underestimated pile areas by 50% and the EEP method overestimated pile bulk volumes by two times. Pile wood volumes from the WRS method (20.0 m3·ha−1 (SE 2.8)) were 30%–50% of those for all other methods (46.1–60.4 m3·ha−1). The EEP method overestimated wood volume if nonspecific PRs were used. The residues to harvest ratio for the WRS method (3.3% (SE 0.45)) was lower than for all other methods (7.5%–9.6%). Total pile wood biomass from LiDAR was 25.4 t dry mass·ha−1 (SE 5.9). Ground-based methods are still required to determine PD or PR. Since their estimation depends on the method used to determine pile area or bulk volume, and may vary with pile size and type, they remain the major source of uncertainty in determining pile wood volumes. However, use of remote sensing techniques to determine the area or bulk volume of all piles in a cutblock can improve estimates of pile wood volumes and biomass.

Full textAbstract:
Sequential exercise-gated cardiac blood pool scintigrams provide a noninvasive technique for evaluating the effect of therapeutic interventions on cardiac volumes and function only if both exercise periods are equivalent in the absence of an intervention. To assess whether they are indeed equivalent, 14 healthy subjects underwent gated blood pool scintigraphy during two maximal upright exercise periods separated by 60 min without changing position. Although resting cardiac output and blood pressure returned to base-line values 60 min after the first exercise period, mean resting heart rate was markedly higher (89.4 +/- 2.7 vs. 66.5 +/- 2.5 beats/min, P less than 0.001) and upright cardiac volumes lower [39.1 +/- 4.9 vs. 56.3 +/- 6.0 ml, P less than 0.001, for end-systolic volume (ESV) and 112.6 +/- 8.0 vs. 144.9 +/- 9.0 ml, P less than 0.001, for end-diastolic volume (EDV)] than before the first exercise period. These differences persisted during low levels of the subsequent exercise but not at high and maximum work loads. Cardiac volumes and heart rate 60 min after an identical exercise protocol in a second group of 22 subjects who received propranolol, 0.15 mg/kg iv, after their initial exercise, however, were the same as those preexercise. Thus higher sympathetic tone may be responsible for the persistently higher heart rate and decreased cardiac volumes after exercise, and the assumption that cardiac volumes and function are similar during two closely spaced sequential exercise studies is not always valid.

Full textAbstract:
At resting end expiration [functional residual capacity (FRC)], the actions of the left and right hemidiaphragms on the lung are synergistic. However, the synergism decreases in magnitude as muscle tension decreases. Therefore, the hypothesis was tested in anesthetized dogs that the degree of synergism between the two hemidiaphragms also decreases with increasing lung volume. In a first experiment, the changes in airway opening pressure (ΔPao) and abdominal pressure (ΔPab) obtained during simultaneous stimulation of the left and right phrenic nerves (measured changes in pressure) at different lung volumes were compared with the sum of the pressure changes produced by their separate stimulation (predicted changes in pressure). Although the pressure changes decreased markedly with increasing lung volume, the measured ΔPao and ΔPab were substantially greater than the predicted values at all lung volumes. The ratio of the measured to the predicted ΔPao, in fact, remained constant. In a second experiment, radiographic measurements showed that the fractional shortening of the muscle during bilateral contraction at high lung volumes was similar to that during unilateral contraction. During unilateral contraction at high lung volumes, however, the passive hemidiaphragm moved in the cranial direction, whereas, during unilateral contraction at FRC, it moved in the caudal direction. These observations indicate that 1) for a given muscle tension, the synergism between the two halves of the diaphragm is greater at high lung volumes than at FRC; and 2) this difference is primarily related to the greater distortion of the muscle configuration.

Full textAbstract:
<em>The study analyzes a unique time period of sustained deflation from 1867 to 1896, followed by sustained reflation after 1896. We use these periods to test two hypotheses concerning the impact on NYSE trading volumes and seat prices. The first is the “liquidity-trading” hypothesis, which hypothesizes that liquidity trading, a component of total trading volume, is positively correlated with interest rates. The second is the price-volume relationship, which hypothesizes a positive relationship between stock prices returns and changes in trading volume. These hypotheses suggest that NYSE trading volume should fall (rise) with falling (rising) stock prices and interest rates. We find strong support for both hypotheses, and additionally show that the impact of stock market prices on trading volumes is highly asymmetrical. As well, the study argues and finds evidence that the high level of systematic risk found in the pricing of NYSE seats is another reflection of the price-volume relationship. Therefore, the study finds strong evidence of a link between deflation, reflation and market liquidity as reflected in trading volumes and the pricing of NYSE seats.</em>

Full textAbstract:
For many geotechnical purposes, the proper estimation of shapes and dimensions of landslide rupture zones is of significant importance. Very often, this exact delineation is difficult due to the lack of information on rupture zone extents in 3D. Based on a global landslide inventory, this work presents statistical analyses correlating dimension-related and shape-related parameters characterizing a rupture zone in 3D to its volume. Dimension-related parameters are approximated by linear regressions increasing with greater volumes, whereas shape-related parameters appear stable throughout the entire range of volumes. Revealing themselves as very stable, these correlations can be used, hence, to extrapolate from a distinct parameter to the volume of a landslide rupture zone. In a second stage, ratios of dimension-related parameters are correlated with rupture zone volumes. Furthermore, this type of correlation delivers very stable results showing that ratios are constant throughout the entire range of volumes. Making use of this ratio consistency, it is possible to deduce one of the two parameters when the other one is given. This latter aspect seems to be promising for remote sensing surveys when initial rupture areas or rupture volumes should be delineated or for numerical modeling of landslides in 3D.

Haematococcus pluvialis cells were cultured in aerated liquid Bold’s Basal medium in two-stage (initial stage during in 7 weeks for increased biomass growth and second stage during in 3 weeks for increased lipid accumulation) with different volumes 250 mL, 10 L, and 1,000 L. With a volume of 250 mL, the medium was supplied with benzyl adenine (BA), indole-3-acetic acid (IAA) or gibberellic acid (GA3) at concentration from 0.1 - 0.2 mg/L in initial stage and IAA or GA3 at concentration from 0.1 - 0.2 mg/L in second stage. After 10 weeks of culture, results showed that supplement of 0.1 mg/L BA in initial stage and 0.125 mg/L IAA in second stage increased cell density, and microalgal cells had green color with a spherical shape. On the contrary, supplement of 0.15 mg/L IAA in initial stage and 0.175 mg/L GA3 in second stage increased lipid accumulation, and microalgal cells had red color with a spherical shape. With a volume of 10 L, the medium was supplied with 0.1 mg/L BA in initial stage, and treated with separation or combination from 2 - 3 of these factors (nitrogen starvation, 0.5% NaCl, 4.98 mg/L FeSO4) were applied in second stage. The result showed that the cultures was treated with nitrogen starvation increased dry biomass and biofuel, but treated with 4.98 mg/L FeSO4 only increased biofuel. With a volume of 1,000 L, microalgal cells were cultured in BB liquid medium in initial stage, and treated with 4.98 mg/L FeSO4 increased fresh 78.67 mg/mL and dry biomass 2.05 mg/L and total lipid content 28.24 %/ DW.

Full textAbstract:
Abstract Many upland oak forests in the eastern United States are approaching economic and biological maturity. A study was established in 1981–1984 in three central Connecticut forests to examine the effects of six distinct cutting methods (shelterwood, diameter limit, multiaged crop tree, high grading, silvicultural clearcut, forest preserve) on stand growth and dynamics in sawtimber oak stands. Board-foot volumes (International 1/4) averaged 8.4 mbf/ac before the initial harvest. Sixty-nine percent of sawtimber trees had butt-log grades of 2 or better. Volume growth was significantly lower on high grading plots (36 bf/ac/year) than on the forest preserve, diameter limit, shelterwood, and multiaged crop tree plots (∼214 bf/ac/year) through two cutting cycles. Total board-foot yield (final volumes plus harvested volumes) for the silvicultural clearcut plots (7.3 mbf/ac) was significantly lower than for uncut, shelterwood, and diameter limit cuts, 12.3, 12.5, and 13.0 mbf/ac, respectively. This study showed that three distinct cutting methods: shelterwood, multiaged crop tree, and forest preserve resulted in similar stand volume growth rates in sawtimber oak stands. The first two methods can be used by landowners who wish to generate income to offset expenses. The choice will depend on the aesthetic and regeneration goals of the landowner. Diameter-limit cutting also had similar volume rates, but it was necessary to lower the diameter limits for the second cutting cycle to maintain economically viable harvests. As a consequence, residual stand structure after the second cutting cycle was similar to that for the high grading plots. Although high grading had the highest harvested volume during the first cutting cycle, low quality of residual trees and depressed stand growth rates indicate it is not a viable option for long-term forest management.

This collection contains 26 short articles, divided into three sets. The first set attempts to provide an overview of sociolinguistic issues in Canada from historical, demographic, and policy perspectives. The second set treats aboriginal languages and the two official languages, French and English; this set includes two articles on language teaching – restricted, however, to the teaching of international languages, mainly as first languages, and to the teaching of French as a second language through immersion methods. The third set offers language profiles of each of Canada's ten provinces, as well as of its two (now three) territories. The organization of the book is meant to provide different angles on sociolinguistic issues in Canada, but unfortunately the result too often is that material is either repeated or consistently left out.

This review essay of the two-volume Cambridge History of Capitalism (2014), edited by Larry Neal and Jeffrey G. Williamson, is divided into three parts. First, I describe three chapters from the second volume that I recommend for all economists to add depth to their understanding of the world economy today. Robert C. Allen analyzes the world distribution of income; Randall Morck and Bernard Yeung discuss the history of business groups; and Peter Lindert surveys private and public programs to help the poor. In each case, they analyze historical backgrounds that illuminate current issues. Second, I criticize the definition of capitalism used in these volumes as too expansive to be useful. I argue that this definition mars the essays in first volume by stimulating a fruitless search for capitalism in the millennium before the Industrial Revolution. Third, I describe the essays in this reference work starting from the most recent and ending with those about antiquity. (JEL N00, P10)

However, while one volume focuses specifically on issues of working memory and L2 acquisition and processing, the other provides a broader overview of the interface between memory and bilingualism more generally. Taken together, the volumes present a large array of research and will be a valuable resource for students and researchers interested in issues in bilingual memory, processing and acquisition.

AbstractThe resuscitator bag has been considered the standard for prehospital, ventilatory managment. Recently, the Berg Resuscitation Apparatus (BRA) was developed as an alternative. Two devices were compared for their ability to deliver adequate tidal volumes and efficacy during simulated, single-rescuer CPR In the first phase, emergency care providers ventilated a test lung using a resuscitator bag, BRA, and demand valve. No significant differences between methods were found. During the second phase of the study, subjects performed single-rescuer CPR on a resuscitation mannikin for two minutes, using the bag-valve-mask and the BRA with a mask. The BRA delivered a volume of 0.81±0.26 liters compared to 0.35±0.19 liters using the resuscitator bag. The BRA allows ventilation to be performed as does the traditional equipment. When used in single rescuer CPR, it appears to provide a substantial increase in the tidal volumes delivered.

In recent fossilization literature, two problems have been raised repeatedly (e.g. Han, 2003; Long, 2003; Birdsong, 2004). First, the term ‘fossilization’ lacks a unified definition and, second, it has not been adequately described empirically. The works reviewed here seek to address this situation. Han (2004) describes a conceptual framework within which to understand existing work on fossilization, and Han and Odlin (2005) present a collection of empirical and analytical studies that help to ameliorate both the definitional and empirical shortcomings of contemporary fossilization research. Taken together, these volumes provide an admirable synthesis of existing research and problems, as well as noteworthy analyses of how to move forward empirically. For the moment, however, idiosyncratic perspectives on fossilization still prevail.

The manuscript embodies informative information concerning lexical and morphological features of Turkish of the era as well as transitional forms of Turkish.

Interpretation of bronchodilator (BD) test based on reaction of forced expiratory in one second (FEV 1). For assessing bronchodilator responsiveness of lung volumes, airway resistance remains largely unexplored. Therefore, we assessed the response of pulmonary function parameters to BD to reveal the most responsive parameter. 90 patients with chronic airway obstruction (61 male and 29 female; aged 55±11; post- BD FEV 1 was 63.1+18.3 % predicted) performed spirometry and static lung volume measurements before and after inhalation of BD. We calculated effect size (ES) for each parameter from the difference between two means divided by the standard deviation of baseline score. There was a significant increase both FVC and FEV 1by 8.2 and 12.3 % from baseline (p<0.001). ES were 0.34 for FEV1 and 0.26 for FVC. The ES for lung volumes were from -0.07 (total lung capacity) to -0.31 (residual volume). The ES for sRtot (specific airway resistance) was -0.5 and ES for sGeff (specific effective airway conductance) was 0.95. The parameters of airway resistance and conductance were more responsive for the assessment of pulmonary function changes than spirometry and lung volumes parameters in patients with chronic airway obstruction.

An efficient implicit unstructured grid algorithm for solving unsteady inviscid compressible flows over moving body employing an Arbitrary Lagrangian Eulerian formulation is presented. In the present formulation, the time discretization is performed using a second-order accurate 3-point time integration scheme and the upwind-biased space discretization using second-order accurate finite volume formulation with Venkatakrishnan limiter. The face-velocities of the control volumes are computed using Geometric Conservation Laws. The nonlinear system arising from the implicit formulation is solved using an ILU preconditioned Newton–Krylov iteration at every time step. The computed results for two test cases involving harmonically oscillating NACA0012 airfoil are presented in order to demonstrate the efficacy of the present solver.

This paper investigates the predictive ability of lagged buy-sell volume on current foreign exchange returns. Using novel Euro-Dollar foreign exchange market data from 2007 to 2015, we show that the buy-sell volume has an inverse correlation with current foreign exchange returns. Using conditional regression analysis, buy-sell volumes predict subsequent Euro-Dollar returns. We divide the data into two sub-samples. We use the first sub-sample to create a trading rule, and we use the second sub-sample to test the rule. After adjusting for time-varying calendar effects, we find that a profitable trading strategy exists using only buy-sell volume to predict returns.

The variation in the two-phase flow parameters in a cylindrical body of new geometry and principle of operation are considered for a device for separating solids from air flow, solving the problem of numerical flow modeling. The aim of this research was to analyze the changes in the parameters of a multi-channel cylindrical cyclone in a mathematical model and to compare it with the results of the examined physical model. Studies on the numerical modeling of cyclones are reviewed, and models and equations for complex vortex flow description are applied. Differential equations were numerically solved by the finite volume method using the standard turbulence models of k–ε and RNG k–ε. Numerical modeling of the velocities, pressures, and volumes of both phases of the two-phase flow was performed. The simulation of the volume distribution of the second phase (glass particles) in the cyclone structure at flow rates of 10.9 m/s, 13.9 m/s, and 21.9 m/s was performed. The values obtained were compared with the physical model of the cyclone in question. The mean relative error was ±6.9%.

However, treating large posterior fossa metastases (LPFM) with SRS is challenging because of the potential risk of increased peritumoral edema (PTE) and compression to brain stem and/or obstructive hydrocephalus of the fourth ventricle (4V). METHODS 21 patients (22 LPFM) treated with 2-SSRS were retrospectively reviewed. Volumetric analysis for tumor, PTE, and 4V volume was assessed for objective response. We defined local failure (LF) as ≧ 71.5% of volumetric increase, equivalent to ≧ 20% increase in maximum diameter (RECIST criteria). Kaplan-Meier estimated overall survival (OS), time-to-local failure, and linear mixed model estimated and compared measurements between time points. RESULTS The median age was 61 years (range: 39–79 years), and nine patients (42.9%) were female. The most common primary cancer was NSCLC (47.6%), followed by breast (14.3%) and renal (14.3). Median OS was 13 months (95% CI: 6–24 months) with median follow-up 18 months (range 7–42 months). The median tumor, PTE and 4V volumes at diagnosis were 7.43 cm3, 18.9 cm3, and 0.95 cm3 respectively. At the first follow-up (median 51 days after the second session), mean tumor (–59%, p< 0.0001) and PTE (–47%, p=0.0008) volumes decreased, while mean 4V volume (+35%, p=0.001) increased. Significant volumetric changes were maintained at second (median 179 days after the second session) follow-up for tumor (–43%, p=0.01) and 4V (+44%, p=0.002), but not for PTE (+8%, p=0.87). Tumor LC rate was 83% (95% CI: 64–100%) at 1 year, and no patient developed the post-treatment hydrocephalus requiring CSF diversion or required surgical resection for tumor progression. CONCLUSIONS This is the first report documenting detailed time courses and excellent safety/ efficacy of 2-SSRS for LPFM. Additional studies with longer follow-ups are needed.

Full textAbstract:
The review presents the second volume of the Bibliographic Index publications on the works of M. Bulgakov of 1941–1985, compiled by the working group of the Russian State Art Library. These two volumes are the first complete set of Russian-language studies of Bulgakov. A brief annotation to each bibliographic unit (about four thousand of them) should be recognized as a significant benefit of this book. The second volume of the Index covers Bulgakov’s “boom” of the 1960s, when the forgotten and never-before-published works were revealed to the reading public, and, primarily, the novel “Master and Margarita.” At that time, numerous memoirs about Bulgakov, the first philological articles about his work, and the first books about him began to appear. It was a period of early academic research on Bulgakov. Therefore, the material of the second volume differs significantly from the first but is no less interesting. The sources are divided into domestic and foreign: the first part includes the texts written by Bulgakov and about him, published in the USSR from 1941 to 1985. The second part of the Index includes the Russian-language editions published in other countries.
