Abstract
Background: Fractures of the distal radius occur in 15% of women older than 50 years of age. These fractures are a particular health concern amongst the elderly, who are at risk of fragility fractures, and are associated with long-term functional impairment, pain and a variety of complications. This is a sentinel event as these fractures are associated with 2 to 4 times increased risk of subsequent hip fractures in elderly patients. This is an important concept as it is well established that these patients have an increased risk of falling. Fall prevention is therefore crucial to decrease further morbidity and mortality. The purpose of this study is to investigate the effect of low-magnitude high frequency vibration (LMHFV) on postural stability and prevention of falls in elderly patients post distal radius fracture.

Methods: This is a prospective single-blinded randomized controlled trial. 200 patients will be recruited consecutively with consent, and randomized to either LMHFV (n=100) or control group (n=100). The primary outcome is postural stability measured by the static and dynamic ability of subjects to maintain center of balance on the Biodex Balance System SD. Secondary outcomes are the occurrence of fall, the health-related quality of life (SF-36), Timed Up and Go (TUG) test for basic mobility skills, compliance and adverse events. Outcome assessments for both groups will be performed at baseline 0 months, 6 weeks, 3 months and 6 months time-points.

Discussion: Previous studies have stressed the importance of reducing falls in distal radius fracture elderly patients, and an effective intervention is crucial. Numerous studies have proven vibration therapy to be effective in improving balancing ability in normal subjects. No previous study has applied the device for fracture patients. Our study will be going to translate LMHFV to fracture patients to improve postural stability and prevent recurrent falls. Positive results would provide a large impact in the prevention of secondary fractures and save healthcare costs.

Abstract
Background
The AMBER (Assessment; Management; Best practice; Engagement; Recovery uncertain) care bundle is a complex intervention used in UK hospitals to support patients with uncertain recovery. However, it has yet to be evaluated in a randomised controlled trial (RCT) to identify potential benefits or harms.

Aim
To investigate the feasibility of a cluster RCT of the AMBER care bundle.

Methods
Mixed-method, feasibility cluster RCT. Prospective, quantitative data collected from patients (or proxies lacking capacity) to (i) examine recruitment, retention and follow-up rates; (ii) test trial data collection tools and determine their optimum timing; (iii) test methods to identify use of financial resources; (iv) explore the acceptability of study procedures for health professionals and patients. Descriptive statistical analyses and thematic analysis using the Framework approach.

Results
894 patients were screened, of whom, 220 were eligible and 19 (8.6%) declined to participate. Recruitment to the control arm was challenging; of the 728 patients screened, 647 (88.9%) were excluded. 65 (81.3% of the recruitment target) patients were recruited. Many were elderly (≥80 years 46.2%, n=30, mean-77.8 years SD=12.3 years). Over half (53.8%) had a non-cancer diagnosis, with a mean of 2.3 co-morbidities. 24.6% patients (n=16) died during their hospital stay and 35.4%, (n=23) within 100 days of discharge. In both trial arms, baseline IPOS subscale scores identified ‘moderate’ patient anxiety (mean 13.3 (SD 4.8) control, 13.3 (SD 5.1) intervention), and howRwe identified a ‘good’ care experience (mean 13.1 (SD 2.5) control, 11.5 (SD 2.1) intervention). Collection of quantitative service use/quality of life data was feasible. No patient participants regarded study involvement negatively. Focus groups with health professionals identified concerns regarding (i) subjectivity of the intervention eligibility criteria; (ii) the need to prognosticate to identify potential patients; (iii) consent procedures and questionnaire length.

Conclusions
A full trial of the AMBER care bundle is technically feasible but impractical due to inherent issues with recruitment arising from the intervention eligibility criteria. Since this complex intervention continues to be used in clinical care and advocated in policy, alternative research approaches must be considered and tested.

Abstract
Background: Within the field of plastic surgery free tissue transfer is common practice for knee and lower leg defects. Usually, after such free flap reconstruction patients undergo a dangling protocol in the postoperative phase. A dangling protocol is designed to gradually subject the free flap to increased venous pressure resulting from gravitational forces. Worldwide there are multiple variations of dangling protocols. However, there is no evidence available in the literature that supports the use of a dangling protocol.
Methods: This is a multicenter randomized controlled trial that includes patients with a free flap lower leg reconstruction. The primary outcome is to assess whether a no-dangling protocol is not inferior to a dangling protocol in terms of proportion of partial flap loss, six months after surgery. Secondary objectives are to identify differences in major and minor complications, length of stay, costs, and to objectify blood gaseous changes during dangling. Furthermore, at 2 years we will assess difference in physical function, infection rates and osseous union rates.
Discussion: The primary outcome of this study will give a more decisive answer to the question whether a dangling protocol is necessary after a free flap reconstruction of the lower leg. The secondary outcomes of this study will provide a better insight into the physical functions, infection rates and union rates in these patients.

Core Ideas
The response of some wheat varieties to gibberellic acid (GA3) hormone under salinity stress was evaluated.
Use of GA3 was successful for alleviating the adverse effects of salinity.
Genetic element plays a vital role in the variations among the varieties.
Salinity is one of the primary abiotic stresses, especially in arid and semiarid regions. An experiment was conducted in a controlled condition at Yangzhou University, Jiangsu, China, to determine whether the gibberellic acid (GA3) might be alleviating the harmful effects of NaCl on germination and early seedling growth attributes. In this investigation, four varieties (Argin, Imam, Xumai 30, and Yang 11‐10), four salinity levels (0, 100, 200, and 300 mM NaCl), and three concentrations of GA3 (0, 0.29, and 0.58 mM) were tested. Germination rate, germination percentage, shoot length, root length, dry weight, STI (salt tolerance index), and SVI (seedling vigor index) were affected by the interactions between variety and salinity and by interactions between salinity and GA3. Water uptake, germination percentage, and root length were affected by the interactions between variety and GA3. At the 300 mM salinity level, 0.58 GA3 increased water uptake by 33.9% and Argin had the highest germination rate (35.6), shoot length (0.64 cm), dry weight (3.7 mg plant −1), STI (22.2), and SVI (0.75). Moreover, among all hormone levels used in this study, 0.58 mM was most effective on most parameters that measured. These results suggest that soaking the seeds in GA3 solutions can reduce the influence of growing salinity problems worldwide.
Annual Cereal Cover Crops Following Winter Wheat Produce High Quality Fall Forage

Published: April 2019

Core Ideas
Forage quality of fall‐grown annual cereal cover crops was high in southern Ontario, Canada.Oat produced more forage than barley when disease pressure was high.Oat–pea forage had higher crude protein with similar yield and nutrient digestibility versus oat.Fertilization (50–67 kg N ha−1) increased yield without affecting quality.Oat seeded at 80 and 120 kg ha−1 had similar forage yield and quality.
Fall‐grown cereal cover crops can serve dual purpose as forage in southwestern Ontario, Canada. Four experimental field trials and four on‐farm validation trials were conducted to evaluate yield and quality of late‐summer sown and fall harvested barley (Hordeum vulgare L.), oat (Avena sativa L.), and an oat–pea (Pisum sativum L.) mixture. Barley, oat, and the oat–pea mixture had similar yields where 50 to 67 kg N ha−1 was applied and when barley yields were not limited by Septoria (Septoria passerinii Sacc) leaf spot. Forage yields were increased at three of four experimental field trials by 0.3–0.7 Mg ha−1) when harvest was delayed from late October to mid‐November. Later harvest dates increased nonfiber carbohydrates (NFC) (51–99 g kg−1) and decreased neutral detergent fiber (NDF) (16–54 g kg−1) and crude protein (CP) (19–47 g kg−1) with minimal effect on total digestible nutrients (TDN). Mid‐fall harvested oat forage with 50 to 67 kg N ha−1 produced an average yield of 2.9 Mg ha−1. Oat forage quality was consistently high. Individual trial oat averages for NDF did not exceed 509 g kg−1, in‐vitro neutral detergent fiber digestibility (NDFD) was not less than 690 g kg−1, increased NFC was not less than 285 g kg−1 and TDN always exceeded 720 g kg−1. Addition of peas, increased CP by 28 g kg−1, with minimal impact on other nutritional quality characteristics. Oat or oat–pea mixtures, seeded as cover crops following winter cereal harvest are capable of producing satisfactory forage yields with excellent nutritional quality.

Published: April 2019

ABSTRACTAryloxyphenoxypropionate (AOPP) herbicides, such as fluazifop‐P‐butyl, can be used for postemergence control of grassy weeds in zoysiagrass (Zoysia spp.), although the turf might suffer transient injury. This injury can be reduced by tank mixing fluazifop‐P‐butyl with triclopyr, an herbicide that behaves as a safener for AOPP herbicides. To characterize seasonal variation in zoysiagrass injury caused by fluazifop‐P‐butyl and triclopyr applications, we conducted a 2‐yr study on three Zoysia spp. cultivars (‘Empire’, ‘Geo’, and ‘Zeon’) at Jay, FL, from August 2015 to April 2017, evaluating how injury and turf quality were affected after spring, summer, and fall applications. The level of injury and changes in turf quality were influenced by fluazifop‐P‐butyl application timing, but the most sensitive season varied with the cultivar. The seasons with the greatest injury were also the ones in which the safening activity of triclopyr was most effective. In addition, when triclopyr was applied with fluazifop‐P‐butyl, the quality of all evaluated cultivars recovered to the level of nontreated controls by 2 wk after treatment. Nonstructural carbohydrate content was not affected by herbicide applications, but there were major differences in glucose and starch content between above‐ and belowground tissue depending on cultivar and season. Overall, our study confirmed that tank mixing triclopyr can reduce fluazifop‐P‐butyl phytotoxicity in zoysiagrass, and in the case of relatively tolerant cultivars, it might allow the use of rates higher than the current labeled rate with little negative impact on turf quality while providing better control of both broadleaf and grassy weeds.

Pragmatics is one of linguistics studies that is quite attractive to learn more about. There are many aspects of pragmatics; one of them is dealing with speech acts. Speech acts consist of many categories; one of them is directive speech act. This study aims to identify the directive speech act performed in “Sleeping Beauty” movie. Likewise, it will find out how often the directive speech act performed and which type of directive speech act that are most frequently used in the movie. This study used qualitative method in which data collection is done by watching the movie, analyzing the body movement and the dialogues of each character, reading the script and library research. A total of 139 directive speech acts were successfully identified. The result of analysis showed that the directive speech act of ordering is the most frequently used in the movie (21,6%). The least frequently used directive speech act is inviting directive speech act (0,7%). The study also revealed the importance of directive speech act in keeping the flow of storyline of the movie. This study is expected to give some useful insights in understanding what directive speech acts is.

AbstractChanges in precipitation have a great influence on human beings. The study of precipitation can aid in understanding regional climate change characteristics and the hydrological cycle. Therefore, in this study, the standardized precipitation index is combined with a simple linear regression test, Mann–Kendall trend analysis, Sen's slope method, principal component analysis and partial correlation analysis to study precipitation and drought distributions in the Songhua River Basin and the causes of precipitation changes in this area. The results are as follows: (1) The average annual precipitation change in this area is not significant, but there are significant differences in seasonal precipitation changes. (2) On a long-term time scale, this area presents a wet trend from southeast to northwest. On a short-term time scale, spring and winter show a wet trend. Winter has changed significantly. Summer and autumn show a dry trend. (3) The average annual and rainy season (RS) precipitation shows step change characteristics. Precipitation change in RS is the main reason for annual precipitation change. (4) The Asian meridional circulation/zonal index have significant effects on precipitation and dry/wet changes in this area. The western Pacific subtropical high and the East Asian summer monsoon are also important factors in this area.

Published: April 2019

Background:
Utilization of macroalgae has gained much attention in the field of pharmaceuticals,
nutraceuticals, food and bioenergy. Macroalgae has been widely consumed in Asian countries as food from ancient
days and proved that it has potential bioactive compounds which are responsible for its nutritional properties.
Macroalgae consists of a diverse range of bioactive compounds including proteins, lipids, pigments, polysaccharides,
etc. Polysaccharides from macroalgae have been utilized in food industries as gelling agents and drug
excipients in the pharmaceutical industries owing to their biocompatibility and gel forming properties. Exploration
of macroalgae derived sulfated polysaccharides in biomedical applications is increasing recently.

Method:
In the current review, we have provided information of three different sulfated polysaccharides such as
carrageenan, fucoidan and ulvan and their isolation procedure (enzymatic precipitation, microwave assisted
method, and enzymatic hydrolysis method), structural details, and their biomedical applications exclusively for
bone tissue repair and regeneration.

Results:
From the scientific results on sulfated polysaccharides from macroalgae, we conclude that sulfated polysaccharides
have exceptional properties in terms of hydrogel-forming ability, scaffold formation, and mimicking
the extracellular matrix, increasing alkaline phosphatase activity, enhancement of biomineralization ability and
stem cell differentiation for bone tissue regeneration.

Conclusion:
Overall, sulfated polysaccharides from macroalgae may be promising biomaterials in bone tissue
repair and regeneration.

POLÍTICA DAS IMAGENS: ESTÉTICA, VISIBILIDADE E DIREITO
Authors: Rabenhorst Eduardo Ramalho 
Published: April 2019

Em que pese não ser propriamente uma novidade no campo dos estudos jurídicos, o tema da estética vem despertando um interesse crescente entre os juristas. Centros de investigação em torno da relação entre estética e direito foram criados em diversas universidades e não são poucos os livros e artigos publicados sobre o assunto. Percebe-se que os juristas não apenas estão explorando as fecundas e variadas possibilidades de conexão do direito com mundo das artes e da literatura, mas também estão produzindo reflexões importantes sobre a forma do direito, elemento essencial da juridicidade.
O texto que se segue faz parte desse interesse geral do direito pelo tema da estética, porém o vocábulo “estética” tem aqui mais relação com o estudo das experiências sensoriais da percepção do que propriamente com as artes. Em outras palavras, o presente trabalho integra uma linha teórica que, combinando intimamente estética e teoria social, busca entender o papel que a sensibilidade desempenha no funcionamento do corpo social e na existência das pessoas que dele fazem parte (Carnevali, 2013).

Es importante prevenir los delitos informáticos y garantizar la privacidad, ya que hoy en día han aumentado los delitos y cada día son más graves. La privacidad constituye una preocupación tanto para los individuos como para las corporaciones, es por ello que se necesita atacar dichos delitos en la medida de lo posible.
La cantidad de datos e información digital ha aumentado con el inicio del internet y el adentramiento en la red mundial; casi toda esta comunicación es lícita, pero las computadoras, redes, telecomunicaciones y la información electrónica también se utilizan para cometer delitos y perfeccionar las técnicas delincuenciales, creciendo nuevas formas de robo y sabotaje de la información.
Los avances tecnológicos les han permitido tanto a los delincuentes, como a los grupos criminales el obtener un medio efectivo por el cual conseguir víctimas que caigan en sus redes y que se expongan en situaciones de peligro. Ninguna persona elige ser víctima de un delito, sólo se expone por falta de precaución y desconocimiento de sus derechos. Estos delitos se enfocan en afectar la privacidad de corporaciones y jaqueo de información en el ámbito económico. lo que resulta en daños económicos a empresas y particulares y que les impone gastos en la protección de información y restauración de la información pérdida.
También existen afectaciones que afectan a la sociedad en general, especialmente al grupo vulnerable de las mujeres, pues entre esos delitos se hallan aquellos que enfatizan su denigración y la violencia existente en países como México, con una cultura tradicionalista y marcadamente patriarcal, como la del acoso virtual, el sexting, la prostitución y trata, entre otros.
Clustering University Programs in Accounting to Enhance Selection Productivity: Precursor to Recommendation System Development
Authors: Alawadhi Abdullah , Byrnes Paul E. 
Published: April 2019

ABSTRACT
Selecting prospective programs in higher education can be a problematic and inefficient task for applicants. In particular, one of the most significant challenges entails locating a specific subset of programs likely to be a good fit. In this paper, clustering techniques are employed in evaluating a specifically created data set of AACSB-accredited doctoral programs in accounting so as to aggregate them by type. In so doing, one is then better positioned to identify which schools best align with his/her relevant characteristics and objectives, thus gaining insight concerning the most appropriate subset of schools to initially consider for application purposes. This approach provides meaningful differentiation between the various program types, offers a means for improving productivity relative to the university application process, and demonstrates promise as an initial foundation for eventual construction of a program recommendation system for use in ostensibly any program application initiative within the higher education domain.
