Effect of home-based exercise on functional ability of hemodialysis patients: a systematic review and meta-analysis

Background and purpose: Hemodialysis patients suffer from impaired functional ability. Several pilot studies have been conducted concerning the effect of home-based exercise on functional ability of hemodialysis patients; however, there have been observed some contradictions between the results of these studies. The aim of this study was, therefore, to determine the effects of home-based exercise on functional ability of hemodialysis patients using meta-analysis. Methods : In this review study, for the purpose of finding studies published electronically form 2000 to 2016, the papers published in journals indexed in the databases of “PubMed, Science Direct, Google Scholar” were used. Also, to analyze the full text of these articles, Stata Software Version 11 was used. Heterogeneity index between the studies was determined using Cochran (Q) c and I2 tests. Since heterogeneity was observed between the studies, a random effect model was used to estimate the mean score of the standardized difference of a 6-minute walk test in order to measure the functional ability of hemodialysis patients in two experimental and comparison groups. Results : Four articles were finally selected in this meta-analysis. 68 patients were in the experimental group and 65 were in the control group. After the intervention, the mean score of the standardized difference of a 6-minute walk test in the experimental group with a confidence interval of 95% was 0.21 (-0.15, 0.57) units more than before the intervention, which was statistically not significant. Conclusion : The results of the meta-analysis showed that home-based exercise increased the functional ability of hemodialysis patients although this effect was not significant. exercise on functional ability of hemodialysis patients; however, there have been some contradictions between their results. These contradictions cause some uncertainties about the effect of home exercise on increasing the functional ability of hemodialysis patients. These contradictions can be resolved using the existing study methods. Meta-analysis is one of these studies that can, by combining the results of earlier studies, provide a general estimate of the care. Therefore, the aim of this study was to determine the effect of home exercise on functional ability of hemodialysis patients using meta-analysis.
Warm Dark Matter Sterile Neutrinos in Electron Capture and Beta Decay Spectra

We briefly review the motivation to search for sterile neutrinos in the keV mass scale, as dark matter candidates, and the prospects to find them in beta decay or electron capture spectra, with a global perspective. We describe the fundamentals of the neutrino flavor-mass eigenstate mismatch that opens the possibility of detecting sterile neutrinos in such ordinary nuclear processes. Results are shown and discussed for the effect of heavy neutrino emission in electron capture in Holmium 163 and in two isotopes of Lead, 202 and 205, as well as in the beta decay of Tritium. We study the deexcitation spectrum in the considered cases of electron capture and the charged lepton spectrum in the case of Tritium beta decay. For each of these cases, we define ratios of integrated transition rates over different regions of the spectrum under study and give new results that may guide and facilitate the analysis of possible future measurements, paying particular attention to forbidden transitions in Lead isotopes.
The Transpose-AMIP II Experiment and Its Application to the Understanding of Southern Ocean Cloud Biases in Climate Models

AbstractThe Transpose-Atmospheric Model Intercomparison Project (AMIP) is an international model intercomparison project in which climate models are run in “weather forecast mode. ” The Transpose-AMIP II experiment is run alongside phase 5 of the Coupled Model Intercomparison Project (CMIP5) and allows processes operating in climate models to be evaluated, and the origin of climatological biases to be explored, by examining the evolution of the model from a state in which the large-scale dynamics, temperature, and humidity structures are constrained through use of common analyses.The Transpose-AMIP II experimental design is presented. The project requests participants to submit a comprehensive set of diagnostics to enable detailed investigation of the models to be performed. An example of the type of analysis that may be undertaken using these diagnostics is illustrated through a study of the development of cloud biases over the Southern Ocean, a region that is problematic for many models. Several models s.
Fumigant toxicity of Pistacia lentiscus essential oil against Tribolium castaneum and Lasioderma serricorne

Abstract This study reports fumigant toxicity of Pistacia lentiscus L . (Anacardiacae) essential oil against 1-7 day-old adults of Tribolium castaneum (Herbst) and Lasioderma serricorne (F.). The chemical composition of the essential oil was assessed via GC and GC-MS. Alpha-phellandrene (3.20%), alpha-pinene (9.48%) and limonene (19.11%) were the major compounds. The mortality of adults was tested in different concentrations ranging from 114 to 1023 µl/l air and different exposure times. Significant differ-ences in insect mortality were observed within insect species, oil concentrations and exposure time. The fumigant toxicity poten-tial of P. lentiscus on L. serricorne was greater (LC 50 = 8.44 µl/l, LC 95 = 43.68 µl/l) than on T. castaneum (LC 50 = 28.03 µl/l, LC 95 = 63.46 µl/l). Moreover, the median lethal time values (LT 50 ) were respectively 18.58 and 41.05 hours. The results suggested that P. lentiscus essential oil may have potential as a control agent against these two stored product beetles.
The Source-Goal Asymmetry in SLA

In lieu of an abstract, here is a brief excerpt: It has been shown in the literature on motion events that there is a strong tendency for speakers of different languages to express goals in preference to sources (e.g. Regier 1997, Ihara & Fujita 2000) and that this linguistic asymmetry could have its origins in non-linguistic event representations (cf. Lakusta & Landau 2005, Lakusta et al. 2007). In this paper, it will be shown that the goal bias in language and cognition has important implications for SLA. In particular, the acquisition of the verbs come and go by Polish speakers of Spanish L2 will be addressed.
Finite Element Modeling of a Microhotplate for Microfluidic Applications

A hand-held chemical laboratory ({mu}ChemLab) is being developed that utilizes a silicon- nitride-supported microhotplate in the front-end, gas sampling and preconcentration stage. Device constraints include low-power (<200mW at 5V), rapid heating (<20msec), and a relatively uniform temperature distribution throughout the heated area ({approximately}3mm{sup 2}). To optimize for these criteria, the electro-thermal behavior of the microhotplate was modeled using Thermal Analysis System (TAS). Predicted steady-state and transient behavior agree well with infrared (IR) microscope data and measured transient response for a low-stress silicon nitride thermal conductivity of k{sub n} = 6.4 x 10{sup {minus}2} W x (cm x {degree}C){sup {minus}1} and a convection coefficient of h{sub cv} = 3.5 x 10{sup {minus}3} W x (cm{sup 2} x {degree}C){sup {minus}1}. The magnitude of h{sub cv} is framed in the context of vacuum measurements and empirical data. Details and limitations of the IR measurement are discussed. Finally, the efficacy of methods for reducing thermal gradients in the microhotplate's active area is presented.
Guess-and-Determine Attack and Algebraic Attack

Recently, algebraic attacks on cryptosystems as a method that tries to solve a system of multivariate polynomial equations, has gained a lot of attention. In this approach, we must do two phases, one phase is to find a system of multivariate polynomial equations and second phase is to solve the system of equations. There are many methods for solving a system of multivariate polynomial equations, such as XL and Gröbner basis algorithms, but these algorithms have a high complexity for a system with many numbers of variables and equations. On the other hand, usually the system of equations, obtained from a cryptosystems, has a high total degree. So one way for reducing the complexity of solving such a system by current algorithms is reducing the total degree of the system and one way for reducing the total degree of the system can be guessing some unknowns in the system. As a contribution, we consider the effect of guessing some unknowns within reducing the total degree of the system of multivariate polynomial equations on the complexity of solving the system by XL and Gröbner basis algorithms.
An overview of the visualization features in open source data mining tools

Typically, data mining tends to predict future patterns and behaviors considering current repositories and warehouses of data. The adoption of open source software provides more independence to the researchers and developers contrasted to the closed source licenses that limit rights. In this research, the authors are going to explore and compare five tools amongst WEKA, Orange, Rapid Miner, Tanagra, and KNIME. The main purpose is to distinguish the chief differences between open source software tools and formerly to classify them into different levels of visualization functions: high support, middle support, and low support. At last, the final assumption revealed that the best software amongst the investigated tools in terms of visualization features is Rapid Miner.
Societal, Culture and Entrepreneurial Opportunities Exploitation of New Venture Activities: Mediating Role of Proactiveness

An unanswered question is concerned with the influence of culture of individualism, power distance and uncertainty avoidance in entrepreneurs’ opportunity exploitation of new venture activities in developing economies in the context of societal level. Based on the sample of 130 individual entrepreneurs in Tanzania, this paper analyses how culture of individualism, uncertainty avoidance and power distance influence entrepreneurial opportunity exploitation of new venture activities on societal level. The results indicated that the culture of individualism contributes highly on entrepreneurs’ opportunity exploitation of new venture activities. The results of uncertainty avoidance imply that the greater the uncertainty avoidance, the less the entrepreneurs’ chance to exploit opportunities of new venture activities. The proactive behaviour that was used as a mediator variable also contributes to the relationship between individualism, uncertainty avoidance and entrepreneurs’ opportunity exploitation of new venture activities. The study has made a contribution to the developing countries literature by focusing on individual entrepreneurs on societal level.
There is a Time to Keep Silent and a Time to Speak, the Hard Part is Knowing Which is Which: Striking the Balance between Privacy Protection and the Flow of Health Care Information

This paper explores fundamental policy trade-offs between health information technology (HIT) and regulatory protection of health information privacy and data security. The paper argues that barriers to HIT development and adoption have been complex, including not just misaligned payment incentives – addressed by the ARRA – but significant implementation issues, risk, “cultural” barriers to adoption, standard-setting issues, network externalities, and regulatory costs. We then focus on one species of regulatory costs that may be especially amenable to reform – those imposed by privacy and data security regulations. We investigate the expected tangible privacy harms related to HIT and find them to be less stark than some believe. We suggest that data security may be a more efficient substitute for many consent and breach notification requirements. We also examine the costs associated with state regulation of medical privacy and find them to be substantial. Although we do not advocate any particular legislative response to the costs of state regulation, we consider the express preemption of state law in the field as a potentially efficient response to those costs.

Opencg: A Combinatorial Geometry Modeling Tool for Data Processing and Code Verification

Combinatorial Geometry (CG) is one formulation for computational geometric models that is commonly used in many neutron transport simulation codes. The use of CG is advantageous since it permits an accurate yet concise representation of complex reactor models with a nominal memory footprint. OpenCG is a software package for combinatorial geometry models being developed at the Massachusetts Institute of Technology. The goal for OpenCG is to provide an easy-to-use, physics agnostic library to build geometry models of nuclear reactor cores. OpenCG is a free, open source library with an easy-to-use Python interface to provide nuclear engineers a single, powerful framework for modeling complex reactor geometries. Compatibility modules for commonly used nuclear reactor physics codes, such as OpenMC, OpenMOC, and Serpent, are being concurrently developed for rapid and easy exportation of an OpenCG model directly into the relevant input ﬁle format for each code of interest. The present work describes OpenCG and describes some of the novel and useful algorithms included with the software package.
Does Migration Reshape Expenditures in Rural Households? Evidence from Mexico

Migration reshapes rural economies in ways that may go beyond the contribution of migrant remittances to household income. Consumption and investment expenditures by migrant-sending households may transmit some of the impacts of migration to others inside and outside the rural economy, and they also may shape the potential effects of migration within the source household. Numerous studies have attempted to quantify the impact of migrant remittances on expenditures in migrant-sending households following one of two approaches. The first asks how migrant remittances are spent. It has the advantage of being simple but the significant disadvantage of ignoring the fungibility of income from migrant and nonmigrant sources. Remittances almost certainly have indirect effects on expenditures by way of their contribution to households' total budgets. The second uses a regression approach that considers remittances as an explanatory variable, in addition to total income and other controls, in a household expenditure demand system. It has the advantage of enabling one to test whether remittances affect expenditures in ways that are independent of their contribution to total income. But it does not take into account other ways, besides remittances, in which migration may influence expenditure patterns in households with migrants. It also may suffer from econometric bias resulting from the endogeneity of migration and remittance receipts. The same variables may simultaneously affect both remittances and household expenditures, and unless one controls for this, biased estimates may result.
Hallux valgus in pedobarographic evaluation

Introduction. Due to its multifactoral and still partially obscure aetiology, hallux vulgus represents a significant diagnostic and treatment problem. Most often, conservative treatment does not bring the expected results, however, if undertaken early, it may curb further deformation. If secondary anatomical changes are present, surgery is the best treatment method. Many authors emphasise that an important factor in the progress of the disease is incorrect distribution of pressure on the instep. In consequence, pedobarographic examinations, which allow for early detection of possible malfunctions, are increasingly often used in diagnostic and prognostic assessment of feet with hallux vulgus. Objective. The study aims to present a comparative analysis of the distribution of pressure on the instep of feet with abnormal inward leaning of the great toe, and healthy feet. Research material and method. The study was conducted on a group of 37 people (70 feet) diagnosed with hallux vulgus. They were compared with a control group of 10 people (20 feet), meeting all the criteria valid for healthy feet. The examination of the distribution of instep pressure was performed using a PEL 39 pedobarographic platform. In order to analyse the distribution of pressure, the feet were divided into Kernozek zones. The results obtained in the course of the pedobarographic examinations were analysed on the basis of the following criteria of a transverse foot arch: FF2 < FF1 and FF3; for oblong arch M < H and M < FF1, FF2, FF3; for three points of support for the foot: the maximum pressure values had to be highest below the heel in the H zone and at the same time, conditions for the oblong and transverse arches also had to be met. Results. The results obtained in the study ascertained that in a group of 70 feet with hallux vulgus, 61 feet did not meet the criteria for a transverse arch of the foot. In the case of 37 of the examined feet, the correct oblong arch was not present. As many as 68 feet did not have three points of support. Conclusions. 1. When compared with healthy feet, feet with hallux vulgus exhibit a different distribution of pressure on the instep; the pressure is significantly higher below the head of the 2nd and 3rd metatarsal bones. 2. A vast majority of the feet studied that had bunion deformities do not meet the criteria for transverse and oblong arches or have a system of three points of support.
Politeness: Always Implicated?.

Based on the relevance-theoretic distinction between explicit and implicit communication, and the notion of explicature of an utterance and its different types (Sperber and Wilson, 1986, 1995; Wilson and Sperber, 1993, 2002), this paper argues that (im)politeness may also be communicated explicitly, and not only implicitly as has been normally claimed in the extant literature. The fact that certain linguistic expressions and paralinguistic features have a procedural meaning that does not affect the truth-conditional content of the utterance where they occur but leads the hearer to obtain a propositional-attitude description can be exploited by the speaker in order to communicate her (im)polite attitude explicitly, as part of the explicit content of that utterance. The hearer will in turn rely on such expressions and features so as to recover a description of the speaker’s attitude and, hence, information about (im)politeness.
Critical Success Factors for Sustainable Entrepreneurship in SMEs: Nigerian Perspective

Global developments now place emphasis on sustainability as an obvious goal and sustainable entrepreneurship has become a novel area of entrepreneurship providing the link between sustainability management, entrepreneurial activities and sustainable development. SMEs form major business establishments across different economies and in view of their numbers, they can play significant role in driving sustainable development and could also be effective in receptiveness to environmental and social problems. The participation of entrepreneurial firms in active sustainability disposition tend to tilt more towards large organisations and industries than Small and medium enterprises (SMEs). The focus of the study therefore is to t establish factors that determine the extent to which SMEs can conduct business in a sustainable manner. The research utilized a descriptive method relying solely on review of secondary data and information in exploring theories underpinning entrepreneurship orientation and drivers of sustainable entrepreneurship behaviour among SMEs. Findings revealed that attitudinal, perceptual factors, firm size, sector, ownership, innovative orientation, personality, management skills, motivation, infrastructure, working capital management, and access to finance (amongst others) are critical to sustainable entrepreneurship among SMEs. The relativity of the observed critical factors to the ease of doing business in Nigeria by SMEs towards sustainable entrepreneurship was emphasised in the study. The study recommends the need for governmental agencies and educational establishments to provide adequate information and enlightenment to foster sustainable entrepreneurship among SMEs.

Microstructure and random magnetic anisotropy in Fe–Ni based nanocrystalline thin films

Nanocrystalline Fe–Ni thin films were prepared by partial crystallization of vapour deposited amorphous precursors. The microstructure was controlled by annealing the films at different temperatures. X-ray diffraction, transmission electron microscopy and energy dispersive x-ray spectroscopy investigations showed that the nanocrystalline phase was that of Fe–Ni. Grain growth was observed with an increase in the annealing temperature. X-ray photoelectron spectroscopy observations showed the presence of a native oxide layer on the surface of the films. Scanning tunnelling microscopy investigations support the biphasic nature of the nanocrystalline microstructure that consists of a crystalline phase along with an amorphous phase. Magnetic studies using a vibrating sample magnetometer show that coercivity has a strong dependence on grain size. This is attributed to the random magnetic anisotropy characteristic of the system. The observed coercivity dependence on the grain size is explained using a modified random anisotropy model.
Estimation of Concentration of Dissolved Organic Matter from Sediment by using UV-Visible Spectrophotometer

The objective of this research was to develop a spectrophotometric technique for estimation of concentration of dissolved organic matter (DOM) from sediment. The results showed that the absorbance 272nm is good surrogate to the concentration of the DOM. In addition, absorption of DOM confirmed to be independent of pH values ranging from 3.0 to 11. Compare to the chemical oxygen demand method and TOC–analyzer, the develop correlation technique using the UV– visible absorption is very straightforward, needs much smaller sample volume, and shows a good reproducibility. The absorbance (272nm) increased with increasing the concentrations of DOM with very high correlation coefficient (R2= 0.98). So it is suggested that this technique should be used as a surrogate for estimation of concentration of DOM from sediment.
