Published: January 2020

Objectives: Chronic prostatitis syndrome is a bothering and poorly understood condition. Many patients report genitourinary pain and Lower Urinary Tract Symptoms as a main complaint. Many different pharmacological or behavioural therapies are prescribed in daily clinical practice, but efficacy data are still lacking. The aim of our study was to test the efficacy and safety of a transrectal delivered association of Boswellia resin extract and propolis derived polyphenols for the relief of prostatitis - like symptoms. Materials and methods: Patients affected by chronic/recurrent prostatitis - like symptoms were prospectively enrolled in our study from December, 2016 to December, 2018. Patients were screened at baseline through clinical examination and validated questionnaires administration: Chronic Prostatitis Symptom Index (CPSI), International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF). Inclusion criteria were: age ≥ 18; prostatitis symptoms persisting for at least 3 of the last 6 months; CPSI pain domain score ≥ 5; previous negative Meares-Stamey test. Treatment consisted on the administration of 1 suppository containing Boswellia resin extract and propolis derived polyphenols, once a day for 20 days. The primary endpoint of the study was the improvement of quality of life after treatment, defined by a reduction of ≥ 2 points, or ≥ 25%, of mean CPSI pain domain score, compared to baseline. Secondary endpoints were the improvement of post-treatment CPSI total score and the analysis of treatment - related adverse events. All patients were re-evaluated 1 month after treatment. Results: 40 patients were enrolled in our study. Median age (Inter - Quartile Range IQR) was 51.5 (41.5-63.2) years. Mean baseline CPSI scores were: 22.15 (total score), 9.67 (pain domain), 5.15 (micturition domain) and 7.35 (quality of life domain), respectively. No significant adverse events were reported. At 1 month follow-up, CPSI scores appeared modified as follows: 16.40 (total score, p = 0.001); 6.92 (pain domain; p = 0.001; 4.02 (micturition domain, p = 0.09); 5.45 (quality of life domain, p = 0.002). Mean CPSI pain domain score reduction was -2.75 points (-28.5%). Mean CPSI total score reduction was -5.75 points (-26%). Conclusions: The association of Boswellia resin extract and propolis derived polyphenols can reduce genitourinary pain and then improve quality of life of men affected by bothersome prostatitis - like symptoms.

Authors: Di Mauro Davide , La Rosa Valentina Lucia , Cimino Sebastiano , Di Grazia Eugenio
Published: January 2020

Purpose: To assess disease-specific and health-related QoL, anxiety and depression as well as satisfaction regarding retrograde intrarenal surgery (RIRS) and miniaturized percutaneous nephrolithotomy (mPCNL) intervention for kidney stones up to 2.5 cm. Secondarily, pain as well as perioperative and postoperative patient outcomes were evaluated. Methods: 60 consecutive patients with kidney stones of dimensions not exceeding 2.5 cm were enrolled in the study of which 30 underwent RIRS and 30 mPCNL. Perioperative characteristics (age, gender, body mass index (BMI), stone side and size, previous interventions for kidney stones and duration of hospitalization) and surgical outcomes (hemoglobin drop, stone-free rate, visual analogue scale (VAS), stenting time, size of ureteral access sheath (UAS) deployment, and postoperative complications) of patients were collected. Quality of life and psychological outcomes were evaluated using validated questionnaires. Results: No significant differences were found between the two groups in terms of age, gender, BMI, stone side and size (p > 0.05). Significant differences between the mPCNL and the RIRS groups were found regarding stenting time (p = 0.032) and duration of hospital stay (p < 0.001). The stone-free rates of mPCNL vs RIRS were not significantly different between the two groups (73.3% vs 66.7%, p > 0.05). Peri- and postoperative complications were not statistically different between the two groups (p > 0.05). RIRS group reported higher anxiety and depression scores compared with the mPCNL group (3 [range 0-15] vs 15 [range 6-24], p < 0.01). We found significant differences between the two groups in social (p < 0.05) and vitality (p < 0.01) scores. VAS pain score was significantly lower in the mPCNL group than in the RIRS one (p < 0.05). Conclusions: These results open new scenarios in the treatment of kidney stones up to 2.5 cm when RIRS and mPCNL have interchangeable indications. Since in our experience complications and success rate are similar, the surgical choice of switching from RIRS to mPCNL in real-time and viceversa may be proposed to the patient in the preoperative counseling.

A 22-year-old female, was referred with a history of a headache and elevated blood pressure without family history of hypertension or familial dyslipidemia. Initially, a spiral computed tomographic angiography of the renal arteries was conducted, demonstrating completely abnormal left renal artery at the medial portion of the vessel with suspicious stenosis, which was supposed to be due to fibromuscular dysplasia (FMD). Subsequently, the patient underwent selective renal angiography and balloon angioplasty. Severe stenosis was observed on the left side and moderate stenosis on the right side in the medial and proximal part of the vessels, respectively. After the diagnosis of FMD, the left side was treated by balloon and finally, the patient was discharged with good control of blood pressure by losartan/amlodipine treatment.

Authors: Cruz-Díaz David , Hita-Contreras Fidel , Martínez-Amat Antonio , Aibar-Almazán Agustin , Kim Kyung-Min
Published: January 2020

Context

Ankle-joint mobilization and neuromuscular and strength training have been deemed beneficial in the management of patients with chronic ankle instability (CAI). CrossFit training is a sport modality that involves these techniques.

Objective

To determine and compare the influence of adding self-mobilization of the ankle joint to CrossFit training versus CrossFit alone or no intervention in patients with CAI.

Design

Randomized controlled clinical trial.

Setting

Research laboratory.

Patients or Other Participants

Seventy recreational athletes with CAI were randomly allocated to either self-mobilization plus CrossFit training, CrossFit training alone, or a control group.

Intervention(s)

Participants in the self-mobilization plus CrossFit group and the CrossFit training-alone group pursued a CrossFit training program twice a week for 12 weeks. The self-mobilization plus CrossFit group performed an ankle self-mobilization protocol before their CrossFit training, and the control group received no intervention.

Main Outcome Measure(s)

Ankle-dorsiflexion range of motion (DFROM), subjective feeling of instability, and dynamic postural control were assessed via the weight-bearing lunge test, Cumberland Ankle Instability Tool, and Star Excursion Balance Test (SEBT), respectively.

Results

After 12 weeks of the intervention, both the self-mobilization plus CrossFit and CrossFit training-alone groups improved compared with the control group (P < .001). The self-mobilization plus CrossFit intervention was superior to the CrossFit training-alone intervention regarding ankle DFROM as well as the posterolateral- and posteromedial-reach distances of the SEBT but not for the anterior-reach distance of the SEBT or the Cumberland Ankle Instability Tool.

Conclusions

Ankle-joint self-mobilization and CrossFit training were effective in improving ankle DFROM, dynamic postural control and self-reported instability in patients with CAI.
Swim-Training Volume and Shoulder Pain Across the Life Span of the Competitive Swimmer: A Systematic Review
Authors: Feijen Stef , Tate Angela , Kuppens Kevin , Claes Anke , Struyf Filip
Published: January 2020

Background

Competitive swimmers are exposed to enormous volumes of swim training that may overload the soft tissue structures and contribute to shoulder pain. An understanding of training factors associated with the injury is needed before practice guidelines can be developed.

Objectives

To investigate the relationship between swim-training volume and shoulder pain and to determine swim-training volume and shoulder pain prevalence across the life span of the competitive swimmer.

Data Sources

Relevant studies within PubMed, Web of Science, and MEDLINE.

Study Selection

Studies that assessed the relationship between a defined amount of swim training and shoulder pain in competitive swimmers.

Data Extraction

Twelve studies (N = 1460 participants) met the criteria. Swimmers were grouped by age for analysis: young (<15 years), adolescent (15–17 years), adult (18–22 years), and masters (23–77 years).

Data Synthesis

Adolescent swimmers showed the highest rates of shoulder pain (91.3%) compared with other age groups (range = 19.4%–70.3%). The greatest swim-training volumes were reported in adolescent (17.27 ± 5.25 h/wk) and adult (26.8 ± 4.8 h/wk) swimmers. Differences in exposure were present between swimmers with and those without shoulder pain in both the adolescent (P = .01) and masters (P = .02) groups. In adolescent swimmers, the weekly swim-training volume (P < .005, P = .01) and years active in competitive swimming (P < .01) correlated significantly with supraspinatus tendon thickness, and all swimmers with tendon thickening experienced shoulder pain.

Conclusions

Evidence suggests that swim-training volume was associated with shoulder pain in adolescent competitive swimmers (level II conclusion). Year-round monitoring of the athlete's swim training is encouraged to maintain a well-balanced program. Developing athletes should be aware of and avoid a sudden and large increase in swimming volume. However, additional high-quality studies are needed to determine cutoff values in order to make data-based decisions regarding the influence of swim training.

It is a popular misconception that all patients with malignant disease die in great pain, in fact, few patients do have this problem. It can be dealt with by radiation — particularly for bone pain, cytotoxic, and analgesic drugs. Regular use of drugs is better than waiting for pain to become severe.

BACKGROUND: Restricting entry and access to highly sensitive systems like e-Health services is vital to protect the privacy and confidentiality of customers. User authentication is implemented predominantly done using Bio-metric schemes. But there is a challenge in securely storing the fingerprint templates. Since fingerprints are permanent, fingerprints getting stolen will be a serious issue.OBJECTIVE: The objective of this paper is to design a scheme to carry out the fingerprint match at the cloud server that will not compromise the fingerprints.METHODS: When users input their fingerprint, a unique key is generated and it is sent to the server for verification.RESULTS: We evaluated our proposed scheme and ascertained that it generates unique Fingerprint Identification Number for different fingerprints and the false rejection rate of our proposed scheme is within acceptable limit.CONCLUSION: The proposed scheme overcomes the security threats to the stored fingerprints of users.

Abstract. A new capture vaporizer (CV) has been developed and used recently in the Aerodyne aerosol mass spectrometers (AMS) and aerosol chemical speciation monitors (ACSM) instead of the standard vaporizer (SV) to reduce the particle bounce. It is important to characterize the CV performance in different environments. In this study, we characterized specific organic aerosols (OA) from vehicle, cooking, biomass burning, and coal burning emissions by a Time-of-Flight ACSM (TOF-ACSM) with the CV. Their corresponding marker ions that have been defined in the previous SV-based analysis are still valid in the CV mass spectra. Spectra of OA from cooking and vehicle exhaust show similarities in distinct alkyl fragments but different ratios of m/z 55 and 57. Ions related to polycyclic aromatic hydrocarbons are present in the OA spectra obtained from burning lignite and bituminous coal, but not in the spectra obtained from burning anthracite. Although the relative intensities of m/z 60 and 73 are much lower in the CV spectra than in the SV spectra for biomass burning OA, they are still relatively greater compared with the spectra for other sources. Our data suggest an atmospheric background of f60 of below 0.03 % for CV. Moreover, we deployed the CV TOF-ACSM along with a SV AMS in urban Beijing during the winter of 2017 to characterize ambient OA with strong anthropogenic influences. The CV TOF-ACSM shows a collection efficiency (CE) of about unity. The CV and SV data show consistent mass concentrations of sulfate, nitrate, ammonium, and OA. Six OA factors are identified by the positive matrix factorization (PMF) analysis for both the CV and the SV data. The SV and CV PMF factors show good correlations in mass concentrations. The SV and CV factors related to coal combustion and cooking differ significantly in loadings, explained by the PMF uncertainty and the lack of understanding of the relative ionization efficiency (RIE) and CE for primary OA. The CV factors related to secondary sources show greater loadings than the SV factors, which may be associated with the changes of signal-to-noise ratios of various ions in the PMF analysis. Our results support improved mass quantification and useful source identification by the CV for ambient particles in the polluted urban environment. The difference in factor loadings between SV and CV should be considered when interpreting or comparing the PMF results among studies.
Data-constrained assessment of ocean circulation changes since the middle Miocene in an Earth system model

Published: January 2020

Abstract. Since the middle Miocene, 15 Ma (million years ago), the Earth’s climate has undergone a long-term cooling trend, characterised by a reduction in sea surface temperatures by over 6 °C, with 4 to 6 °C cooling occurring in the deep ocean. The causes of this cooling are primarily thought to be linked to changes in ocean circulation due to tectonic plate movements affecting ocean seaways, together with and a drop in atmospheric greenhouse gas forcing (and attendant ice-sheet growth and feedback). In this study we assess the potential to constrain, using marine sediment proxy data, the evolving patterns of global ocean circulation and cooling of surface climate over the last 15 million years (Ma) in an Earth system model. We do this by compiling surface and benthic ocean temperature and benthic carbon-13 data in a series of seven time-slices spaced at approximately 2.5 million year intervals. We pair this with a corresponding series of seven tectonic and surface climate boundary condition reconstructions in the cGENIE (muffin release) Earth system model. In the cGENIE model, we adjust atmospheric CO2 together with the magnitude of North Pacific to North Atlantic salinity flux adjustment in a series of 2D parameter ensembles in order to match global temperature and benthic δ13C patterns in the model to the data. We identify that a relatively high CO2 equivalent forcing of 1120 ppm is required at 15 Ma in cGENIE to reproduce proxy temperature estimates in the model, noting that this CO2 forcing is dependent on cGENIEs climate sensitivity (which is as the present day) and that it incorporates the effects of all greenhouse gases. The required CO2 forcing progressively reduces throughout the subsequent six time slices delineating the observed long-term cooling trend. In order to match the evolving patterns of the proxy data, we require fundamental change in the mode of ocean circulation at 12.5 Ma with present-day-like benthic δ13C trends established by 10 Ma. We also find a general increasing strength of Atlantic overturning despite a reduction in salinity of the surface North Atlantic over the cooling period, attributable to falling intensity of the hydrological cycle and polar cooling caused by CO2-driven global cooling.

Published: January 2020

Abstract. We investigate in this paper the sensitivity of the representation of the Denmark Strait overflow produced by a regional z-coordinate configuration of NEMO (version 3.6) to the horizontal and vertical grid resolutions and to various numerical and physical parameters. Three different horizontal resolutions, 1/12°, 1/36° and 1/60°, are used respectively with 46, 75, 150 and 300 vertical levels. Contrary to expectations, in the given numerical set-up, the increase of the vertical resolution did not bring improvement at eddy-permitting resolution (1/12°). We find a greater dilution of the overflow as the number of vertical level increases, and the worse solution is the one with 300 vertical levels. It is found that when the local slope of the grid is weaker than the slope of the topography the result is a more diluted vein. Such a grid enhances the dilution of the plume in the ambient fluid and produces its thickening. Although the greater number of levels allows for a better resolution of the ageostrophic Ekman flow in the bottom layer, the final result also depends on how the local grid slope matches the topographic slope. We also find that for a fixed number of levels, the representation of the overflow is improved when horizontal resolution is increased to 1/36° and 1/60°, the most drastic improvements being obtained with 150 levels. With such number of vertical levels, the enhanced vertical mixing associated with the step-like representation of the topography remains limited to a thin bottom layer representing a minor portion of the overflow. Two major additional players contribute to the sinking of the overflow, the breaking of the overflow into boluses of dense water which contribute to spread the overflow waters along the Greenland shelf and within the Irminger Basin, and the resolved vertical shear that results from the resolution of the bottom Ekman boundary layer dynamics. This improves the accuracy of the calculation of the entrainment by the turbulent kinetic energy mixing scheme (as it depends on the local shear), and improves the properties of the overflow waters such that they more favorably compare with observations. At 300 vertical levels the dilution is again increased for all horizontal resolutions. The impact on the overflow representation of many other numerical parameters were tested (momentum advection scheme, lateral friction, bottom boundary layer parameterisation, closure parameterisation, etc.) but none had a significant impact on the overflow representation.
Stochastic simulation of streamflow and spatial extremes: a continuous,
wavelet-based approach
Authors: Brunner Manuela I. , Gilleland Eric
Published: January 2020

Abstract. Stochastically generated streamflow time series are used for various water management and hazard estimation applications. They provide realizations of plausible but yet unobserved streamflow time series with the same temporal and distributional characteristics as the observed data. However, the representation of non-stationarities and spatial dependence among sites remains a challenge in stochastic modeling. We investigate whether the use of frequency-domain instead of time-domain models allows for the joint simulation of realistic, continuous streamflow time series at daily resolution and spatial extremes at multiple sites. To do so, we propose the stochastic simulation approach called Phase Randomization Simulation using wavelets PRSim.wave which combines an empirical spatio-temporal model based on the wavelet transform and phase randomization with the flexible four-parameter kappa distribution. The approach consists of five steps: (1) derivation of random phases, (2) fitting of kappa distribution, (3) wavelet transform, (4) inverse wavelet transform, and (5) transformation to kappa distribution. We apply and evaluate PRSim.wave on a large set of 671 catchments in the contiguous United States. We show that this approach allows for the generation of realistic time series at multiple sites exhibiting short- and long-range dependence, non-stationarities, and unobserved extreme events. Our evaluation results strongly suggest that the flexible, continuous simulation approach is potentially valuable for a diverse range of water management applications where the reproduction of spatial dependencies is of interest. Examples include the development of regional water management plans, the estimation of regional flood or drought risk, or the estimation of regional hydropower potential among others.
Determining the dependence of the power supply to the ocean on the length and time scales of the dynamics between the meso-scale and the synoptic-scale, from satellite data
Authors: Wirth Achim
Published: January 2020

Abstract. The input of mechanical power to the ocean due to the surface wind-stress, in regions which correspond to different regimes of ocean dynamics, is considered using data from satellites observations. Its dependence on the coarse-graining range of the atmospheric and oceanic velocity in space from 0.5° to 10° and time from  6 h to 40 days is determined. In the area of the Gulf Stream and the Kuroshio extensions the dependence of the power-input on space-time coarse-graining varies over tenfold for the coarse-graining considered. It decreases over twofold for the Gulf Stream extension and threefold for the Kuroshio extension, when the coarse-graining length-scale passes from a few degrees to 0.5° at a temporal coarse-graining scale of a few days. It increases over threefold in the Gulf Stream and the Kuroshio extensions when the coarse-graining passes from several days to 6 h at a spatial coarse graining of a few degrees. The power input is found to increase monotonically with shorter coarse-graining in time. Its variation with coarse graining in space has no definite sign. Results show that including the dynamics at scales below a few degrees reduces considerably the power input by air-sea interaction in regions of strongly non-linear ocean currents. When the ocean velocities are not considered in the shear calculation the power-input is considerably (up to threefold) increased. The dependence of the power input on coarse graining in space and time is close to being multiplicatively separable in all regions and for most of the coarse-graining domain considered.
The role of large-scale dynamics in an exceptional sequence of severe thunderstorms in Europe May/June 2018
Authors: Mohr Susanna , Wilhelm Jannik , Wandel Jan , Kunz Michael , Portmann Raphael , Punge Heinz Jürgen , Schmidberger Manuel , Grams Christian M.
Published: January 2020

Abstract. Over three weeks in May and June 2018, an exceptionally large number of thunderstorms hit vast parts of western and central Europe, causing precipitation of up to 80 mm and several flash floods. During this time, the large-scale atmospheric circulation, which was characterized by a blocking situation over northern Europe, influenced atmospheric conditions relevant for thunderstorm development. Initially, the southwesterly flow on the western flank of the blocking anticyclone induced the advection of warm, moist, and unstably stratified air masses. Due to a low-pressure gradient associated with the blocking anticyclone, these air masses were trapped in western and central Europe, remained almost stationary and prevented a significant air mass exchange. In addition, the low-pressure gradient led to weak flow conditions in the mid-troposphere and thus to low vertical wind shear that prevented thunderstorms from developing into severe organized systems. Most of the storms formed as local-scale, relatively slow-moving single cells. However, due to the related weak propagation speed, several thunderstorms were able to produce torrential heavy rain that affected local-scale areas and triggered several flash floods. Atmospheric blocking also increased the upper-level cut-off low frequency on its upstream regions, which was up to 10 times higher than the climatological mean. Together with filaments of positive potential vorticity (PV), the cut-offs served as trigger mechanisms for a majority of the thunderstorms. For the 22-day study period, we found that more than 50 % of lightning strikes can be linked to a nearby cut-off low or PV filament. The exceptional persistence of low stability combined with weak wind speed in the mid-troposphere over three weeks has not been observed during the past 30 years.
Leda atómica de Dalí. Fotografía y pentagrama místico
Authors: Oliver-Torelló J. Carles
Published: January 2020

El arte en general y algunas obras en particular están relacionadas con teorías tan conocidas como las propias obras, sirviendo para glosarlas. Las explicaciones pueden ser de los propios autores y otras estar elaboradas por teóricos, como críticos e historiadores, aunque muchas no pueden considerarse axiomas absolutos. En el caso de la Leda atómica de Dalí, la literatura generada en torno a ella es muy abundante, destacándose las hipótesis del proceso de realización de la pintura, en donde, pretendidamente, se ha recurrido a una geometría muy sofisticada para su composición con el asesoramiento matemático de Matila Ghyka. Los tópicos se han visto acrecentados por la actitud y personalidad histriónica del pintor. A la vista de los datos reales acreditados, estos varían, cuando no contradicen claramente las explicaciones al uso. La utilización de una fotografía para copiarla minuciosamente en la pintura y el uso retórico de las teorías geométricas de la proporción divulgadas por Ghyka, superponiéndolas en la Leda, son datos fundamentales para la comprensión de la obra.
Reflexiones en torno a la noción de arte sonoro y los límites y contextos del grafismo musical
Authors: García Isaac
Published: January 2020

Este artículo aborda diversas aproximaciones a la categoría de arte sonoro con el fin de cuestionar algunos de los argumentos estéticos e históricos que supuestamente la sustentan. Por una parte, se revisarán algunas ideas vinculadas a la noción de arte sonoro como disciplina claramente diferenciada del campo de la creación musical. En el lado opuesto, la concepción del arte sonoro como un campo emergente y punto de encuentro de distintas disciplinas en disolución plantea otras interesantes reflexiones, como la imposibilidad de alcanzar una efectiva legitimación simbólica a través de un canon independiente, los procesos que argumentan la asimilación del propio término, la aceptación de la música como una posible categoría agotada, etc. Las contradicciones que se derivan de esta línea argumental cuestionan si se trata únicamente de un debate de naturaleza teórica o artística o si, más bien, son otros aspectos –de carácter sociológico– los que operan efectivamente en la creación y delimitación de los diversos contextos del arte sonoro. En este sentido, el grafismo musical, desde su concepción como manifestación artística híbrida, pone de relieve algunos mecanismos ideológicos que niegan que su presencia/ausencia dentro de los espacios del arte sonoro se deba únicamente a motivos de naturaleza artística.
Movimiento Moderno y derecho a la ciudad: prefiguraciones y contradicciones en el diseño urbano de postguerra
Authors: Sevilla-Buitrago Álvaro
Published: January 2020

La noción de ‘derecho a la ciudad’ es hoy un slogan popular tanto en la academia como en las políticas institucionales y los movimientos sociales. Muchas de estas manifestaciones, sin embargo, se alejan del sentido inicial que Henri Lefebvre asignó al concepto hace más de 50 años. Su fórmula original era en sí misma esquiva y requiere una contextualización en el ciclo de trabajos desarrollados por el autor entre 1960 y mediados de los 1970s. El trabajo de Lefebvre en este período ha sido presentado rutinariamente como una crítica de la arquitectura y el urbanismo del Movimiento Moderno, triunfantes tras la Segunda Guerra Mundial. Sin embargo parte de las indagaciones del diseño de esta época anticipan, de forma contradictoria, las inquietudes que después encontrarán pleno desarrollo en el trabajo de Lefebvre. Este artículo comienza identificando cuatro aspectos centrales en la formulación original del derecho a la ciudad: la idea de la ciudad como ‘obra’ colectiva, la noción de ‘vida urbana’, el derecho a la ‘centralidad’ y el concepto de ‘espacio diferencial’. Posteriormente rastrea una tradición de experiencias en torno a los CIAM que entre las décadas de 1940 y 1960 anticiparon, de forma incompleta y a menudo conflictiva, parte de estos elementos.

Published: January 2020

This study highlights the analysis of Pakistani students for Derivational and Inflectional Morphemes at intermediate level. Derivational and Inflectional Morphemes are the elements which explores the field of morphology for daily language users. Morphology is the study of “morphemes”. Morphemes are the smallest units of language that have described into two categories as free and bound morphemes. The main issue that exists in this study is to analyze the derivational and inflectional morphemes used by Pakistani students. Through the perceptions and understanding of inflectional and derivational morphemes, this study can produce the vocabulary in which one word have multiple meanings. This research paper is associated with linguistics and field of socio linguistics. This paper is purely based on qualitative research approach. In this study, the researcher founds the prominent dimensions caused by the inflectional and derivational morphemes, when attached with other morphemes. If the derivational morpheme is attached with free morpheme, it will convey different meaning and a chance have that it will change even word class. While inflectional morpheme will play a grammatical role when will be attached with free morpheme.

Learning system is developing fast. The learning process has become easier than before. Technology has taken the place of an immensely important tool of the learning system. E-mails, Facebook, Instagram, Twitter, Imo, Line App and WhatsApp are some of the most important, common, social, immediate messaging tools. WhatsApp is generally used on the mobile phones. It is one of the most popular tool for immediate messaging, transferring ideas, knowledge and pictures for fun, and, of course, for learning. WhatsApp incorporates an ultimate solution for learners, teachers and teacher educators. It facilitates easier communication among the learners, teachers and teacher educators. It could be another venue for learners, teachers and teacher educators. Learning could be achieved faster through this channel. Technology has been used as a tool for instructions in many interesting ways. Students as well as instructors use mobile in various ways, and feel satisfied, feel to be there, feel to be with one another as well. Technology, in our mobile age, has been incorporated into almost all curricula. “Tandem learning may be found as more compatible than any other kind”. (Khan.2018, P-1) Hence, this paper is going to show how the WhatsApp could be a means of allocating as well as distributing educational resources and information to learners, teachers and teacher educators. Whether, it could be a strategy to enhance the learning process faster and easier. Whether, it could be an interesting experience for learners, teachers and teacher educators. Is it attainable? Is it time-friendly? I hope this research paper will accommodate the responses and will try to find a conclusion. WhatsApp is a mobile instant messaging App, which is used immensely for so many reasons. It is simple, popular and versatile. Therefore, the aim of the study is to discover the influence as well as the waves of the use of mobile, and especially, the ‘WhatsApp’ as a tool in boosting the process of ESL/EFL pedagogy.

This work aimed to analyze the economic feasibility of the irrigation system by dripping and nitrogen fertilization in jambu production. The experiment was conducted at the Experimental Farm of Igarapé-Açu, a site owned by UFRA, in protected cultivation, from May to July in 2016. The treatments consisted in four soil water tensions (12, 18, 24 and 30 kPa) and four nitrogen doses (0, 50, 100 and 150 kg ha-1). The economic analysis of the jambu irrigated production was sustained by the theory of producing costs considering both depreciation cost and alternative cost. The treatment with the highest profit was managed at 18 kPa with a nitrogen dose of 50 kg ha-1, with a profit of R$ 1,548.54 for an area of 1,000 m.². The drip irrigation and nitrogen fertilization were economically viable for the jambu crop.

Background:

The goal of computer navigation in total knee arthroplasty (TKA) is to improve the accuracy of alignment. However, the relationship between this technology and implant longevity has not been established. The purpose of this study was to analyze survivorship of computer-navigated TKAs compared with traditionally instrumented TKAs.

Methods:

The PearlDiver Medicare database was used to identify patients who underwent a primary TKA using conventional instrumentation versus computer navigation between 2005 and 2014. Conventional and computer-navigated cohorts were matched by age, sex, year of procedure, comorbidities, and geographic region. Kaplan-Meier curves were generated to estimate survivorship with aseptic mechanical complications, periprosthetic joint infection, and all-cause revision as end points.

Results:

During the study period, 75,709 patients who underwent a computer-navigated TKA were identified and matched to a cohort of 75,676 conventional TKA patients from a cohort of 1,607,803 conventional TKA patients. No difference existed in survival between conventional instrumentation (94.7%) and navigated TKAs (95.1%, P = 0.06) at 5 years. A modest decrease was found in revisions secondary to mechanical complications associated with navigation (96.1%) compared with conventional instrumentation (95.7%, P = 0.02) at 5 years. No differences in revision rates because of periprosthetic joint infection were observed (97.9% versus 97.9% event-free survival, P = 0.30). In a subgroup of Medicare patients younger than 65 years of age, use of computer navigation was associated with a decrease in all-cause revision (91.4% versus 89.6% event free survival, P = 0.01) and revision secondary to mechanical complications (89.6% versus 87.8% event-free survival, P = 0.01) at 5 years.

Discussion:

Among Medicare patients, no notable difference existed in TKA survival associated with the use of computer navigation at the 5-year follow-up. Use of computer navigation was associated with a slight decrease in revisions secondary to mechanical failure. Although improved survivorship was associated with patients younger than 65 years of age who had a navigated TKA, generalizability of these findings is limited given the unique characteristics of this Medicare subpopulation.

This qualitative study aims to scrutinize the traumatic effects of rhetorical and political excitable speech acts in Toni Morrison’s most commended novel Beloved, which presents haunting situations of slavery in USA. The novel demonstrates that the white masters attempt to interpellate the minds of the black slaves in order to make them recognize that they are sub-human creatures. These interpellative forces consequence in life time enslavement of the victims, since they never come out of the traumatic effects of the verbal abuse, they were victimized with. The data are collected from Toni Morrison’s novel, Beloved, which presents haunting situations in which the black slaves after their freedom, evoke in their mind traumatic memories of their slavery. In order to examine the traumatic speech acts, relevant excerpts were taken through purposive sampling under the method of content analysis. The applied theoretical model is based on Judith Butler’s postulates about burning speech acts presented in her famous book, Excitable Speech. The analysis of the selected traumatic speech acts shows that the pricking state of the victims’ self and ego traumatize them even after they get freedom. They repeat the injurious speech acts and atrocities of the white masters to further aggravate the situations through traumatic speech acts.

The aim of this paper was to examine the selected physical and motoric characteristics of students with mild intellectual disabilities. The total number of the participants was 119 (54 females and 65 males) and the mean age was 10.78 ± 1.88 years. Height, weight, body mass index (BMI), body fat percentage, and body fat mass scores were collected to determine the physical characteristics. Handgrip strength, vertical jump, standing long jump, flexibility, and 20 m speed running tests were performed to determine the motoric characteristics. The data were analyzed using IBM SPSS 22 package program. Descriptive statistical methods were used in the evaluation of the data. The male students performed better than the female students in all motor performance tests except the flexibility test. The older students performed better, as in the previous studies. Most of the students in the study were found to have a low or normal body mass index. However, according to the literature, children with special needs tend to be overweight and obese due to sedentary lifestyle. One reason for this difference might be a small sample size. Other reasons could be different socio-economic backgrounds and different extracurricular physical activity habits.

Toezicht en handhaving van Europees voedselveiligheidsrecht door de NVWA; de Nieuwe Controleverordening (EU) 2017/625

Ambtenaren van de NVWA houden toezicht op de naleving van het Europese en nationale voedselveiligheidsrecht. De bevoegdheden daartoe ontlenen zij aan de Algemene wet bestuursrecht en de Warenwet. Op 14 december 2019 is EU-Verordening (EU) 2017/625 inzake deze officiële controles van toepassing geworden. Deze verordening gaat ook in op onderwerpen die niet (afdoende) zijn geregeld in het nationale recht. Dit artikel laat zien hoe het toezicht van voedselveiligheidsrecht is geregeld in de context van de nieuwe Verordening (EU) 2017/625 inzake officiële controles en toont de impact op het bestuursrecht op drie onderwerpen: de mystery shopper, risicogeoriënteerd toezicht en verplichte handhaving.

Verordening (EU) 2017/625 van het Europees Parlement en de Raad van 15 maart 2017 betreffende officiële controles en andere officiële activiteiten die worden uitgevoerd om de toepassing van de levensmiddelen- en diervoederwetgeving en van de voorschriften inzake diergezondheid, dierenwelzijn, plantgezondheid en gewasbeschermingsmiddelen te waarborgen (…), PbEU 2017, L 95/1.
The problem of effective deployment architecture in SOA

Published: January 2020

Service Oriented Architecture is popular in many organizations. In particular, it has already deeply rooted in large corporations that need to automate entire business processes and implement them in many systems. It has a unique feature that allows unambiguously indicate service that is to realise business process step.
That indication is possible to show directly in BPMN diagram. Thus, it is possible to trace which server has used resources to implement the service and how much of those resources were needed. Therefore, it is possible to build an optimization task that, with limited and unreliable resources, will determine such allocation of components to servers and such an algorithm for assigning tasks to them, so that the processes will work as well as possible. The article presents a model of such an optimization task. This model consists of four layers. The Organization Layer describes the system environment – the types and frequency of initiating business process instances. The Integration Layer describes the business processes and indicates the services that should be performed at every step. The Component Layer describes component characteristics and what services they provide. In Server Layer both: server characteristics and runtime environments necessary for the component to run are described. Finally, the optimization task and evaluation criteria are formulated.
