Published: April 2018

AbstractAs a common mineral phase on Earth and Martian regolith, natural rutile was reported as a potential candidate for use as a Fenton catalyst in this study. The influences of Fe and V in various chemical states on the generation of reactive oxygen species (ROSs) and the catalytic activity of rutile were examined. A series of rutile samples with various surface and bulk states of Fe and V were obtained initially by hydrogen annealing of natural rutile at ~773–1173 K. X-ray diffraction, electron paramagnetic resonance spectra, and X-ray photoelectron spectroscopy demonstrated that the atomic fractions of Fe(III) and V(V) decreased sharply with increasing temperature, along with the accumulation of surface Fe(II) and bulk V(III). All as-prepared materials showed enhanced Fenton degradation efficiency on methylene blue (MB) compared with P25-TiO2, and the treated samples exhibited up to 3.5-fold improvement in efficiency at pH 3 compared to the untreated sample. The improved efficiency was attributed mainly to Fenton catalysis involving Fe(II) and V(III). The dissolved Fe2+ played a crucial role in the homogeneous Fenton reaction, while the bound V(III) favored adsorption primarily and may have facilitated heterogeneous Fenton reaction and the regeneration of Fe2+. The pH regulated the reaction mechanism among homogeneous (pH = 3) and heterogeneous (pH = 3.7) Fenton catalysis and physical adsorption (pH = 5, 6). The aim of the present study was to improve the understanding of the potential role of natural rutile with advanced oxidation functions in Earth systems and even on Mars, which also provide an inspiration for screening natural rutile and any other similar, Earth-abundant, low-cost minerals for environmental application.

Published: April 2018

Abstract
This study aimed to describe problem behaviors and psychosocial strengths, examine the problem-strength interrelations, and evaluate profiles of problems and strengths in youth with Down syndrome (DS). The community-based sample consisted of 67 parents of children with DS aged between 4 and 19 years. Parents reported about the developmental age (Vineland screener), behavioral problems (Child Behavior Checklist), and psychosocial strengths (Behavioral and Emotional Rating Scale) of their child. Results indicate that attention, social, and thought problems were most prevalent, whereas family involvement and receiving/expressing affection were identified as strengths. A confirmatory factor analysis identified problems and strengths as distinct, yet related, variables. Moreover, a cluster analysis of problems and strengths identified four different profiles. Implications for interventions are discussed.

Published: April 2018

Abstract
This research examined how parenting adults with developmental disabilities affects parental well-being beyond midlife and into old age. Parents of adults with developmental disabilities (n = 249) and parents of adults without disabilities (n = 9,016), studied in their early 50s and mid-60s, were longitudinally tracked into their early 70s. Compared to parents of adults without disabilities, parents of adults with disabilities showed a pattern of normative functioning in their 50s, followed by poorer well-being in their mid-60s, and further declines in health and well-being into the early 70s. Aging parents who co-resided with their adult child with disabilities were particularly vulnerable, experiencing a steeper increase in depressive symptoms and body mass index (BMI) than parents whose child with disabilities lived away from home.

Published: April 2018

AbstractGait is a relevant and complex aspect of motor functioning. Disturbances are related to negative health outcomes. Gait characteristics of 31 adults with intellectual disability (ID) without Down syndrome (DS) (42.77±16.70 years) were investigated, and associations with age, sex, body mass index (BMI), and level of ID were assessed. Sex and BMI were significantly associated with some of the gait parameters, while age and level of ID were not. Gait characteristics of adults with ID seem to be comparable to those of the general population of older adults (average 20 years older), except that adults with ID seem to spend less time in stance and double support phase and walk more variable and with a broader base of support.
Use of induced pluripotent stem cells to investigate the effects of purine nucleoside phosphorylase deficiency on neuronal development
Authors: Tsui Michael , Biro Jeremy , Chan Jonathan , Min Weixian , Grunebaum Eyal 
Published: April 2018

Background: Inherited defects in the function of the purine nucleoside phosphorylase (PNP) enzyme can cause severe T cell immune deficiency and early death from infection, autoimmunity, or malignancy. In addition, more than 50% of patients suffer diverse non-infectious neurological complications. However the cause for the neurological abnormalities are not known. Objectives: Differentiate induced pluripotent stem cells (iPSC) from PNP-deficient patients into neuronal cells to better understand the effects of impaired purine metabolism on neuronal development. Methods: Sendai virus was used to generate pluripotent stem cells from PNP-deficient and healthy control lymphoblastoid cells. Cells were differentiated into neuronal cells through the formation of embryoid bodies. Results: After demonstration of pluripotency, normal karyotype, and retention of the PNP deficiency state, iPSC were differentiated into neuronal cells. PNP-deficient neuronal cells had reduced soma and nuclei size in comparison to cells derived from healthy controls. Spontaneous apoptosis, determined by Caspase-3 expression, was increased in PNP-deficient cells. Conclusions: iPSC from PNP-deficient patients can be differentiated into neuronal cells, thereby providing an important tool to study the effects of impaired purine metabolism on neuronal development and potential treatments. Statement of novelty: We report here the first generation and use of neuronal cells derived from induced pluripotent stem cells to model human PNP deficiency, thereby providing an important tool for better understanding and management of this condition.

Published: April 2018

AbstractIn this paper, we consider a class of nonlinear impulsive neutral partial functional differential equations with continuous distributed deviating arguments. For this class, we establish sufficient conditions for theH-oscillation of the solutions, using impulsive differential inequalities and an averaging technique with two different boundary conditions. We provide an example to illustrate the main result.
Lax Integrability and Exact Solutions of a Variable-Coefficient and Nonisospectral AKNS Hierarchy
Authors: Zhang Sheng , Hong Siyu 
Published: April 2018

Abstract
In this paper, a variable-coefficient and nonisospectral Ablowitz–Kaup–Newell–Segur (vcniAKNS) hierarchy with Lax integrability is constructed by embedding a finite number of differentiable and time-dependent functions into the well-known AKNS spectral problem and its time evolution equation. In the framework of inverse scattering transform method with time-varying spectral parameter, the constructed vcniAKNS hierarchy is solved exactly. As a result, exact solutions and their reduced n-soliton solutions of the vcniAKNS hierarchy are obtained. It is graphically shown that the parity of an embedded time-dependent function has connection with the symmetrical characteristics of the spatial structures and singular points of the obtained one-soliton solutions.
Multilingual Families: A Sociolinguistic Model for Retaining Language Ability and Cultural Heritage
Authors: Bednarek Adam 
Published: April 2018

Abstract

Objective: To propose a model for the creation of selected language practice games that will allow for multilingual families to engage in common activities in order to retain the multiculturalism factor amongst parents and their children.

Methodology: Ontological considerations based on sociolinguistic models in accordance with TPACK (Technological Pedagogical Content Knowledge) and SAMR (Substitution, Augmentation, Modification, Redefinition) Models.

Findings: The preservation of this heritage among both children and adults can be achieved by allowing them to engage in various activities, allowing them to acquire multiple languages simultaneously and thus create a sense of national identity.

Value Added: The presented methodological considerations are to be used as the basis for the creation of output results in an Erasmus+ financed project carried out at the University of Social Sciences (along with other European partners) entitled Multilingual Families Clubs: Promoting Linguistic and Cultural Heritage of Europe.

Recommendations: activities for Polish multilingual speakers need to include those in the following languages: German, Russian, Ukrainian, Belarussian.

An Exploration for the Motives behind Enhancing Senior Banker’s Level of Organizational Resilience: A Holistic Case Study
Authors: Mousa Mohamed , Sai Andrew Adjah , Salhin Gehad 
Published: April 2018

Abstract

Objective: the present paper aims to explore the main motives behind Cairo bank’s attempts to raise its senior bankers’ level of organizational resilience.

Methodology: after gathering and investigating all relevant literature about organizational resilience, semi-structured interviews were conducted with 24 of the senior bankers who work at Cairo bank at 6 October city, Giza, Egypt. All interviews were conducted in the Arabic language.

Findings: the findings of this study show that senior bankers at Cairo bank, like many other Egyptian classes, struggle in a state of uncertainty and consider it the main motive behind their bank’s attempt to raise their resilience level. The pressure of stakeholders is, to a large extent, present, and there is a thought that fulfilling different societal obligations is a source for economic gains and accordingly, stakeholders’ pressure is a second motive behind raising employees’ organizational resilience. Furthermore, organizational culture adaptability and the tendency to responsively act in line with unpredicted events is a third motive. Finally, senior bankers’ loud voice in calling for continuous grants for education and training has come to be the fourth motive.

Value added: the paper is considered the first to qualitatively investigate organizational resilience in Egypt.

Recommendations: The researchers are of the view that the development of every departmental agenda for needed resilience is a priority for improving organizational capacity. Moreover, reformulating the bank’s values, operations and activities should also be considered to create a harmony between the external threats and the internal duties. Furthermore, there should be also an orientation to redefine the concept of “uncertainty” from time to time to include socio-political and socio-economic types of risk.
Persian leopard and wild sheep distribution modeling using the Maxent model in the Tang-e-Sayad protected area, Iran
Authors: Jafari Ali , Zamani-Ahmadmahmoodi Rasool , Mirzaei Rouhollah 
Published: April 2018

AbstractThe maximum entropy (Maxent) model was used to predict the distribution of Persian leopards and wild sheep in the Tang-e-Sayad protected area in Iran. For this purpose, eight variables, as well as 30 occurrence points of leopard and 98 points of wild sheep, were used. Two techniques, density-based occurrence points thinning and performance-based predictor variables selection were used to improve the results of the model. The model results were analyzed based on four threshold limit-based statistics (sensitivity, specificity, kappa and true skill statistics) and area under the curve (AUC), followed by determining the relative importance of variables based on the jackknife procedure. The results of threshold limit-based statistics revealed that the success of the model for distribution prediction of leopard and wild sheep were good and relatively good, respectively. According to the jackknife procedure, for wild sheep and for leopard, slope and distance to road, respectively, were the most important predictor variables. The results also indicated that the efficiency of the model did not improve by reducing the density of occurrence points for the wild sheep (AUC=0.784–0.773). However, the selection of predictor variables slightly improved the performance of the model (AUC=0.794–0.819). The results of the study also showed overlapping habitat for two species due to both human and ecological reasons for which we proposed some conservation actions such as excluding domestic grazing, controlling illegal poaching and restoration of old migratory corridors.
Partial and complete leucism in two Abrothrix species (Rodentia: Cricetidae) from central Chile
Authors: Rubio André V. , Simonetti Javier A. 
Published: April 2018

Abstract
Rodents with leucism (a hypopigmentary congenital disorder) in the Neotropical region are rarely recorded. During field surveys in central Chile, we found in commercial Monterrey pine plantations a specimen of Abrothrix longipilis and a specimen of Abrothrix olivaceus with partial leucism. Another A. olivaceus exhibited complete leucism. To our knowledge, this is the second documentation of leucism in rodents from Chile and the first record of leucism in A. longipilis. Leucism may be expressed in small and isolated populations due to inbreeding. This suggests that land-use change in this area is probably affecting the genetic diversity of these rodent species.

AbstractThe restricted triangulation existence problem on a given graph decides whether there exists a triangulation on the graph’s vertex set that is restricted with respect to its edge set. LetG=C(n,S) be a circulant graph onnvertices with jump value setS. We consider the restricted triangulation existence problem forG. We determine necessary and sufficient conditions onSfor whichGadmitting a restricted triangulation. We characterize a set of jump valuesS(n) that has the smallest cardinality withC(n,S(n)) admits a restricted triangulation. We present the measure of non-triangulability ofKn−Gfor a givenG.

Published: April 2018

Abstract
This study originated from events that occurred in 2014 in an Italian hospital, where the embryos of a couple, obtained by means of homologous insemination, were mistakenly implanted into the uterus of another woman who, along with her husband, underwent the same treatment.
Faced with this serious adverse circumstance, that gives rise to ethical and legal issues, the authors conducted a comparative examination of how to consider the division of maternity (between biological mother and uterine mother) and the related division of paternity (between genetic father and legal father, husband or partner of the gestational mother).
Some preliminary observations are made concerning parenthood and filiation within the context of currently applicable Italian law.
The following is a detailed analysis of the arguments in favour of the parental figures involved (gestational mother/genetic mother).
Formation of 1-aza-2-silacyclopentanes and unexpected products from the insertion of phenylisocyanate into 2,2-dimethyl-1-(trimethylsilyl)-1-aza-2-silacyclopentane
Authors: Herbig Marcus , Böhme Uwe , Schwarzer Anke , Kroke Edwin 
Published: April 2018

Abstract
Substances like 3-aminopropyltriethoxysilane are often used as adhesive promoters in various formulations for coatings or to adjust the properties of siloxanes and other polymers. Cyclisation of similar substances is also interesting because of the formation of the Si-N bond. 1-Aza-2-silacyclopentanes were synthesised from 3-aminopropylalkoxysilanes by intramolecular condensation reactions and substitution reactions at the silicon atom. The products tend to undergo ring-opening polymerisation. In contrast to literature reports, they can only be isolated as N-substituted derivatives. Phenylisocyanate inserts into the Si-N bonds of cyclic aminosilanes to form seven-membered heterocycles. Furthermore, phenylisocyanate reacts with N-H bonds in the same molecule. Two insertion products were isolated, and their crystal structures were determined.

Published: April 2018

Abstract
Introduction. Exercise tolerance is one of the life quality parmeters in chronic heart failure patients. The aim of our study was to assess the quality of life of patients with chronic heart failure by estimating their exercise tolerance.
Methods. We examined 113 patients with stable chronic heart failure in the period of 18 months. They were divided in two groups, a control group (on conventional therapy of angiotensin-converting enzyme inhibitors and diuretics) and a therapy group (conventional therapy plus beta-blockers). The therapy group was divided into 3 subgroups according to the beta-blocker taken (a Metoprolol Bisoprolol and Carvedilol subgroup).
Exercise tolerance was detected by coronary trade-mill stress testing every 6 months (only in patients of NYHA FC II and III), symptoms limited or modified after 6-minutes Bruce test. Results. Our results showed that there was a statistically significant difference between the control group and all the therapy subgroups in NYHA FC, NYHA score and exercise tolerance at the end of the study, but there was no difference among the subgroups.
Conclusion. Beta-blockers improve the exercise tolerance as a variable defining quality of life.

Published: April 2018

Abstract
Introduction. Kidney transplantation from a living donor is a superior method for treatment of end-stage renal disease (ESRD). The aim of this report is to show that the intellectual inferiority should not be an obstacle for the success of this treatment modality.
Case report. We present a 25-year-old female patient with physical and intellectual impairment, with focal-segmental glomerulonephritis diagnosed in 2006 as primary cause of ESRD, regularly followed up at the Department of nephrology. She was initiated on hemodialysis (HD) since July 2014. Although with a bad compliance and hypertension, a good dialysis adequacy was managed with a reduction of the extracellular volume (ECV) and kidney transplantation was indicated as a more convenient treatment option.
With psychological assessment of the intellectual inferiority being not contraindication for kidney transplantation and highly motivated family she was transplanted in March 2015. Postoperatively, she was with prolonged hospitalization because of the delayed graft recovery and a couple of perioperative urinary and surgical site infections. In the following months she was slowly adapting to a regular hygienic and diet regimen and intake of medication, with a number of consultations at the Department along with the family. At present, the patient has an excellent health condition and significantly better quality of life.
Conclusion. The physical handicap of a moderate degree and mild intellectual impairment are not a contraiidication for treatment of the terminal kidney disease. A successful kidney transplantation reduces the morbidity and mortality from the primary disease, and improve patient’s overall quality of life.

Education program for controversial defect of recent X-ray instrument termed as a simultaneous small angle X-ray scattering and wide angle X-ray diffraction measuring instrument
Authors: Matsuo Masaru , Bin Yuezhen 
Published: April 2018

AbstractSimultaneous rotations of sample and X-ray detected counter are needed to evaluate orientation distribution of crystallites and amorphous chains oriented predominantly parallel to the film surface in addition to exact diffraction peak profiles obtained without the complicated intensity corrections. The rotation mode is known as “θ–2θscanning” system (θ: film, 2θ: counter). The system has been mainly used in research and development institutes. However, such instruments are not produced at present. Recently, small angle X-ray scattering (SAXS) and wide angle X-ray diffraction (WAXD) intensities have been measured by using X-ray beam generated along one direction. The brand name of the instrument is “a simultaneous SAXS and WAXD measuring instrument”. The X-ray beam generated by the instrument has surely high luminance providing high degree resolution of peak profiles by diffraction and/or scattering. The sample stage and detector, however, are fixed, since the intensities for SAXS and WAXD are obtained by the digital display of the number of X-ray photons detected on the imaging plate. Such optical system contains controversial defect on evaluating orientation of crystal planes parallel to the surface of films prepared by T-die and inflation methods as well as the exact profile. The imaging plate cannot detect the diffraction intensity from the crystal planes existing in the angle range between incident beam and Bragg angle associated with the diffraction peak position of the individual crystal planes.
