Summary
In order to study the soil aggregate distributions and soil organic matter (SOM), we sampled top- and subsoils in four intensively farmed croplands (two organic (Org-OB and Org-LA), and two conventional (Con-OB and Con-LA)) on Haplic Chernozems located in Marchfeld in the east of Vienna (Austria). Soil structure and SOM quantity, quality and distribution between free and occluded particulate organic matter and aggregate size fractions (<20 µm, 20-250 µm, 250-5000 µm) were studied by following a density fractionation procedure with low-energy ultrasound treatment. The relation of the soil physicochemical (e.g., particle size distribution, pH, organic carbon, total nitrogen) and biological properties (e.g., fungal biomass, active fungi) with stable soil aggregate size fractions and SOM was studied. The mean weight diameter (MWD) showed no significant difference between all studied sites and was between 3.8 mm and 10.0 mm in topsoils and between 6.7 mm and 11.9 mm in subsoils. In topsoils, the contents of calcium-acetate-lactate (CAL)-extractable P, active fungal biomass, dithionite-extractable Fe and sand were significantly positively correlated with the amount of the macroaggregates and with the MWD. We observed that most soil organic carbon, depending on soil texture, was stored in the microaggregate size classes <20 µm and 20-250 µm.

Published: August 2017

Abstract
In this paper, we introduce a new class of Hermite multiple-poly-Bernoulli numbers and polynomials of the second kind and investigate some properties for these polynomials. We derive some implicit summation formulae and general symmetry identities by using different analytical means and applying generating functions. The results derived here are a generalization of some known summation formulae earlier studied by Pathan and Khan.

Published: August 2017

AbstractIn the present investigation, synthesis of cumene by transalkylation of 1, 4 DIPB with benzene was studied over cerium modified nano crystalline zeolite X in a fixed bed plug flow reactor. Nano crystalline zeolite X was synthesized and characterized by XRD, SEM, TPD, EDS and FTIR. A series of nanocrystalline zeolite X (MX4, MX6, MX10) modified with ceric ammonium nitrate of different concentrations (4 %, 6 %, 10 %) was used for synthesis of cumene. MX10zeolite was proved to be the most active catalyst over which 27.12 % yield of cumene was obtained at temperature 553K, benzene/1, 4 DIPB mole ratio of 7.5 and space time-10.54 kg h/kmol. Reduction of crystal size (100–500 nm) in MX10increases surface area (633m2/gm) and thereby increases cumene yield. A kinetic rate equation was developed from the product distribution pattern following Langmuir–Hinshelwood approach. Kinetic parameters were estimated by nonlinear regression analysis. The activation energy for transalkylation and isomerisation reaction was found to be 88.86 kJ/mol and 99.04 kJ/mol respectively.

Published: August 2017

AbstractPathophysiological changes that occur during ischemia and subsequent reperfusion cause damage to tissues procured for transplantation and also affect long-term allograft function and survival. The proper preservation of organs before transplantation is a must to limit these injuries as much as possible. For decades, static cold storage has been the gold standard for organ preservation, with mechanical perfusion developing as a promising alternative only recently. The current literature points to the need of developing dedicated preservation protocols for every organ, which in combination with other interventions such as ischemic preconditioning and therapeutic additives offer the possibility of improving organ preservation and extending it to multiple times its current duration. This review strives to present an overview of the current body of knowledge with regard to the preservation of organs and tissues destined for transplantation.
“Cunt”: On the perception and handling of verbal dynamite by L1 and LX users of English
Authors: Dewaele Jean-Marc 
Published: August 2017

Abstract“Cunt” is currently one of the most offensive words in the English language and is usually censored in the English press and media. The present study looks firstly at differences between 1159 first (L1) and 1165 foreign (LX) users of English in their perceived understanding of the word, its perceived offensiveness and their self-reported frequency of use. Secondly, it considers the relationships between the dependent variables and a number of psychological, sociobiographical and linguistic profile variables. The findings suggest that LX users are less sure about the exact meaning of the word, underestimate its offensiveness and use it less frequently than L1 users. Links between understanding of the word and its perceived offensiveness vary for L1 and LX users. High levels of Extraversion, Neuroticism and Psychoticism were linked to more frequent use of the word, as were lower levels of education, a younger age, being a male and working in a swearing-rich environment for both L1 and LX users. Variation in the group of LX users was linked to age of onset of acquisition of English, context of acquisition, self-reported oral proficiency, frequency of use of English and having lived in an English-speaking environment.

Abstract
Isacco, L, Ennequin, G, Cassirame, J, and Tordi, N. Physiological pattern changes in response to a simulated competition in elite women's artistic gymnasts. J Strength Cond Res 33(10): 2768–2777, 2019—The outstanding progress in women's artistic gymnastics in recent decades has led to increased technical and physiological demands. The aim of this study was to investigate (a) the physiological demands of elite French gymnasts and (b) the impact of a competitive routine on physiological pattern changes. Fourteen French elite female gymnasts performed anthropometric measurements, physical fitness tests, and a simulated 4-event competition. Heart rate (HR) was continuously recorded throughout the duration of the simulated competition. Blood lactate concentrations were assessed at rest, before the beginning and at 2, 4, and 10 minutes after completion of the routine on each apparatus. Isometric handgrip strength and anaerobic endurance and power were assessed during the simulated competition. The highest values of HR and blood lactate concentrations were reached during the floor and uneven bar exercises. Blood lactate concentrations and HR kinetics were apparatus dependent and values remained significantly increased at 10 minutes of recovery compared with resting data. Anaerobic endurance and power decreased significantly as the competition progressed (p < 0.001). The present results show specifically cardiorespiratory and anaerobic apparatus-dependent responses throughout a simulated competition. Recovery approaches seem relevant to prevent and minimize fatigue and optimize performance in these athletes.

Abstract
Lipinska, P, and Hopkins, WG. Pacing profiles and competitive performance of elite female 400-m freestyle swimmers. J Strength Cond Res 34(1): 218–224, 2020—Pacing can impact competitive endurance performance. The objective of this study was to determine relationships between pacing parameters and competitive performance of elite female 400-m freestyle swimmers. Publicly available websites provided 50-m split and final times for 381 swims of 20 elite female swimmers in over 150 national and international competitions between 2004 and 2016. Most pacing profiles displayed negative quadratic curvature, with the fifth of the 8 laps being the median slowest. The mean times for the first and last laps were faster than predicted by the quadratic by 5.6 and 1.9%, respectively, and lap-to-lap variability was 0.65%. Scatter plots of each swimmer's final time often showed no obvious relationships with their pacing parameters, suggesting that swimmers compensated for changes in one parameter with changes in another. However, some plots showed a U shape or linear trend that allowed tentative identification of optimum values of the pacing parameters. In these plots, it was apparent that about half the swimmers might make small to moderate improvements (up to ∼1%) by changing the slope or curvature of their pacing profile or by changing time in the first or last laps. This approach for characterizing pacing profiles to identify possible improvements might be appropriate to assess pacing in other sports with multiple laps, frequent competitions, and relatively constant environmental conditions.

Objective
In adults with hyperinsulinaemic hypoglycaemia (HH), in particular those with insulinoma, the optimal diagnostic and management strategies remain uncertain. Here, we sought to characterise the biochemical and radiological assessment, and clinical management of adults with HH at a tertiary centre over a thirteen-year period.

Design
Clinical, biochemical, radiological and histological data were reviewed from all confirmed cases of adult-onset hyperinsulinaemic hypoglycaemia at our centre between 2003 and 2016. In a subset of patients with stage I insulinoma, whole-exome sequencing of tumour DNA was performed.

Results
Twenty-nine patients were identified (27 insulinoma, including 6 subjects with metastatic disease; 1 pro-insulin/GLP-1 co-secreting tumour; 1 activating glucokinase mutation). In all cases, hypoglycaemia (glucose ≤2.2 mmol/L) was achieved within 48 h of a supervised fast. At fast termination, subjects with stage IV insulinoma had significantly higher insulin, C-peptide and pro-insulin compared to those with insulinoma staged I–IIIB. Preoperative localisation of insulinoma was most successfully achieved with EUS. In two patients with inoperable, metastatic insulinoma, peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTATATE rapidly restored euglycaemia and lowered fasting insulin. Finally, in a subset of stage I insulinoma, whole-exome sequencing of tumour DNA identified the pathogenic Ying Yang-1 (YY1) somatic mutation (c.C1115G/p.T372R) in one tumour, with all tumours exhibiting a low somatic mutation burden.

Conclusion
Our study highlights, in particular, the utility of the 48-h fast in the diagnosis of insulinoma, EUS for tumour localisation and the value of PRRT therapy in the treatment of metastatic disease.
Modeling and prescribed H-infinity tracking control for strict feedback nonlinear systems
Authors: Gao Chuang , Jia Yufu , Liu Xiaoping , Chen Ming 
Published: August 2017

By utilizing backstepping technique, an H∞ robust controller with improved prescribed performance and dynamic surface control is designed for a class of strict feedback nonlinear systems. The transient and steady state performance for the tracking errors of nonlinear system can be guaranteed by using improved prescribed performance constraint. The dynamic surface control is used to overcome the differential explosion problem in the backstepping procedure. The impacts of uncertainties in the system are attenuated by H∞control. The performance and stability analysis proves that the controller design procedure is simple with low complexity and robustness. Finally, the simulation results verify the effectiveness of the controller. By comparing with the existing method, the proposed method has a faster convergence speed and better steady state performance, and also the controller design process is simpler.

Published: August 2017

We have developed the flexible scheme for computer-aided detection (CAD) of interstitial lung diseases on chest radiographs. These schemes enable us to perform diagnostics in the broad circumstances of pneumonia and other interstitial lung diseases. It is applied in the case of children pneumonia when conditions are difficult to standardize. In the adults' case the schemes of CAD are more adaptive, as there are more characteristic interstitial lung tissue's changes to all kinds of pathological conditions. Even in the norm of drawing there are more visible and more highlighted features, leading to better results. The CAD scheme works as follows. For the first of all, we are using adopted algorithms of active contours to select the area of lungs, and then to divide this area into subareas - regions of interest (40 different ROI). Then ROIs were subjected to the 2-dimensional Daubechies wavelet transform, and only main transformation was used. For every transformation 12 texture measures were calculated. Principal component analysis (PCA) was used to extract 2 main components for each ROI, and these components were compared to predictive component region.

Authors: Tähtinen Paula A. , Laine Miia K. , Ruohola Aino 
Published: August 2017

BACKGROUND AND OBJECTIVES:Antimicrobial treatment is effective in the management of acute otitis media (AOM), but approximately half of the children may recover without antimicrobial agents. By identifying patients who may not require antimicrobial treatment for the management of AOM, the use of antimicrobial agents could be substantially reduced. Our aim was to identify subgroups of children with AOM who would benefit most from antimicrobial treatment and children who could be suitable for initial observation.METHODS:This is a secondary analysis of randomized, double-blind, placebo-controlled trial. Children 6 to 35 months of age with AOM (N = 319) were randomly allocated to receive amoxicillin-clavulanate (40/5.7 mg/kg per day) or placebo for 7 days. Our primary outcome was time until treatment failure.RESULTS:Treatment failure occurred in 31.7% of all children. Older age (24–35 months) and peaked tympanogram at entry decreased the hazard for treatment failure (hazard ratio, 0.53; 95% confidence interval [CI], 0.29 to 0.96; P = .04; and hazard ratio, 0.43; 95% CI, 0.21 to 0.88; P = .02, respectively). The rate difference for treatment failure between antimicrobial treatment and placebo groups was highest among children with severe bulging of the tympanic membrane (11.1% vs 64.1%; rate difference −53.0%; 95% CI, −73.5% to −32.4%), resulting in a number needed to treat of 1.9.CONCLUSIONS:Children with severe bulging of the tympanic membrane seem to benefit most from antimicrobial treatment of AOM. On the other hand, children with peaked tympanogram (A and C curves) may be optimal candidates for initial observation.

The aim of this work was evaluate the bromatological quality, the degradability of dry matter and the mitigation potential of the forage from the different silvopastoral arrangements in three shade levels (0, 30 y 60%). This study was carried out between October 2012 and September 2013, in the La Candelaria farm from the Antioquia University, Colombia. The arrangements contained within Brachiaria grasses (Brachiaria brizantha cv toledo, Brachiaria decumbens and Brachiaria hibrido cv mulato II) alone or associated with Tithonia diversifolia and Cratilya argentea in silvopastoral arrangements. Evaluation was made in forage of forty days, the chemical composition, content of polyunsaturated fatty acids, degradation of dry matter and in vitro methane production were determined. The arrangement used (grass alone or associated with shrubs affected signi cantly the concentration of protein and linoleic acid (p<0.05). Not effect was observed in the arrangement, level of shade and interaction arrangement x shade in the degradability of dry mater after 48 h (p>0.05). However, pre-planned comparisons indicated that the association of Brachiaria brizantha cv toledo with shrubs improved the degradability of dry matter (MS) at 48 h, and was observed that the interaction shade x arrangement affected the dynamic degradation of MS. The factors evaluated (arrangement and shade) did not affect the in vitro methane emission.

Authors: Elizondo Salazar Jorge Alberto 
Published: August 2017

The objective of this experiment was to determine the effect of cutting height on yield and nutritional quality of three forage species used for feeding dairy cattle. The study was carried out at the “Alfredo Volio Mata” Experiment Station of the University of Costa Rica. The evaluated species were: native corn (Zea mays), black sorghum (Sorghum almum) and king grass cultivar Taiwan (Pennisetum purpureum); these three species were harvested at two different cutting heights (15 and 45 cm above ground). Green forage yield was significantly different (P<0.05) within each of the species and dry matter (DM) yield was reduced between 17 to 42% when cutting height was increased. When cutting height was done at 15 cm above ground, corn, black sorghum and Taiwan yielded 51.3, 31.4 and 70.9 t/ha/ cycle, respectively. With regard to DM, the forage species that yielded the most when harvested at 15 cm above ground was Taiwan grass, with 11.6 t/ha/cycle, while the forage species that yielded the least when harvested at 45 cm was corn with only 5.4 t/ha. Black sorghum signi cantly (P<0.05) improved its nutritive value when cutting height was increased. DM concentration increased from 22.79 to 25.53%, crude protein also increased from 8.24 to 12.90%, meanwhile neutral detergent fiber decreased from 63.69 to 59.47% and acid detergent fiber also decreased from 43.15 to 37.30%.

Published: August 2017

The aim of this study was evaluated by in vitro, the effect of mixing wild sunflower (Tithonia diversifolia), kikuyu (Cenchrus clandestinum) and concentrated feed, with the addition of polyunsaturated fatty acids (AGPI) on the production of methane (CH4 ml/g MSd), dry matter digestibility (%DIVMS) and production of volatile fatty acids (AGV). The research was conducted in NUTRILAB laboratory (Medellin, Colombia) in September 2015. Three combinations of AGPI rich lipid sources were used with a total maximum inclusion level corresponding to 3% of incubated dry matter. Combinations of lipid sources were: SAGPI1: 0.5% soya oil, 0.5% sish oil, 2% rich in omega 3 bypass fat. SAGPI2: 1% Soya oil, 0.5% fish oil, 1.5% bypass fat rich in omega 3. SAGPI3: 2.5% Soya oil, 0.5% fish oil. A source of bypass fat (GSP) was also used. The results were processed using pre-planned test comparisons through the PROC MIXED-SAS.The methane production in vitro decreased (p<0.05), while the dry matter digestibility increased (p<0.05) 24 and 48 hours after wild sunflower was include and / or AGPI or both into the mixtures. In the molar ratio of AGV (%), acetic acid showed an increased presence. The inclusion of forage like wild sunflower and sources of AGPI supplementation in cattle, could be a strategy to reduce methane emissions without causing a detriment to the ruminal fermentation.
Transdanubian Puszta (1683–1735) Based on 18th-Century Border Litigations
Authors: Máté Gábor 
Published: August 2017

Puszta is a widely known phenomenon that primarily denotes a deserted countryside and not the flat areas, vegetation, cattle grazing and some picturesque landscape items that are usually associated with. In Southern Transdanubia, a borderline during Ottoman rule for 143 years, settlement desertion became a crucial and overwhelming factor from 1543 to 1686. My paper addresses the age of reorganization (1686–1720), right after the Ottomans were defeated, and focuses on land use and the general appearance of the land. There are two major views on this situation. Some historians hold that the elaboration took place in a scarcely populated and “wild,” natural area, thus the process of colonization was inevitable. Meanwhile, other scholars who worked with local archival sources have pointed out that plenty of families survived there whose livelihood changed during the Ottoman occupation but they filled the land with human activities. This resulted in a different type of land structure, which was far from the so-called medieval landscape.
In my paper I follow the second theory and depict the landscape in a minor area on the basis of archival data. I analyze the practices of land use in order to show the way the “puszta” did and did not exist. I also investigate the key factors that affected a new landscape shift, which brought about the colonial landscape.
