Search for the Origin of Discrepancies in Osmotic Measurements of the PNIPAM - Water System
Authors: Manek Enikő , Tombácz Etelka , Geissler Erik , László Krisztina
Published: September 2017

Major, still unelucidated, inconsistencies exist in the literature among measurements of the thermodynamic properties of poly(N-isopropylacrylamide) (PNIPAM) solutions and gels. This paper looks for evidence of intrinsic ionic behaviour in cross-linked PNIPAM homopolymer hydrogels synthesized in water under standard conditions. Systematic measurements are made of the swelling and osmotic properties of lightly cross-linked PNIPAM hydrogels, as well as of their potentiometric titration and DSC response, over a wide range of pH and ionic strength conditions, in order to distinguish the effects of the latter two parameters on putative intrinsic ions. The intrinsic ion content of the gel is found to be vanishingly small, and consequently unlikely to be the source of the divergences among past measurements. By contrast, a major finding of this study is that comparison of the present results with the literature reveals that frustrated equilibrium can be a source of substantial discrepancies.

Published: September 2017

Poly(aspartic acid) (PASP) hydrogels were prepared by cross-linking polysuccinimide (PSI) with diaminobutane followed by the mild hydrolysis of the resultant PSI gels to PASP hydrogels. The composition dependence of the gelation time and the stiffness of bulk PASP hydrogels were determined by rheometry and compression tests, respectively. The composition of the prepared PASP nanogels was chosen based on the results on bulk PASP hydrogels. Prior to nanogel preparation stability of DMSO-in-oil (inverse) emulsions was tested as a function of the chemical quality of apolar phase, the concentration of the precursor polymer and the concentration of the surfactant. PASP nanogels in the size of a few hundred nanometers were prepared by the hydrolysis of PSI nanogels synthesized in inverse emulsion. PASP nanogels showed pH-dependent swelling and strongly negative surface charge at physiological pH values, thus they can be further developed to meet the specific criteria of different bio-related applications.

The purpose of the present study was to assess the giomer retention following application of one step self etch adhesive and one-step self-etch adhesive plus an extra hydrophobic adhesive layer in non-carious cervical lesion. Twenty four participants having bilateral cervical lesion at the maxillary premolars teeth were selected. Following cleaning of the cervical lesions, 24 left premolar teeth were restored with giomer by using the one-step self-etch system (Group A) and 24 right premolar teeth were restored with giomer by using one-step self-etching plus extra hydrophobic adhesive layer (Group B). Participants were recalled at 6 and 15 months for evaluating the clinical outcome. The results showed that at 15 months, 18 giomer restorations in Group A and 21 in Group B were intact inside the cavity and no significant difference was found between the two groups. It can be concluded that giomer restoration used with one-step self- etching plus additional adhesive layer slightly improved the retention of the material.

Published: September 2017

Aggressive open lumbar discectomy is the most commonly performed surgical procedure for patients with persistent low back and leg pain. In this retrospective study,  1,380 patients were evaluated for long-term results of aggressive discectomy for the single level lumbar disk herniation. Demographic data, surgical data, complications and reherniation rate were collected and clinical outcomes were assessed using visual analogue score (VAS), Oswestry disability index (ODI) and modified Mcnab criteria. The mean follow-up period was 28.8 months. According to the modified Mcnab criteria, the long-term results were excellent in 640 cases, good in 445 cases, fair in 255 cases, and poor in 40 cases. The mean VAS scores for back and radicular pains and ODI at the end of 2 years were 1.1 ± 1.0, 1.5 ± 0.5 and 6.6 ± 3.1% respectively. The complications were foot drop (n=7), dural tear (n=14), superficial wound infection (n=17), discitis (n=37) and reherniation (n=64). The dural tear and superficial wound infections resolved after treatment but 28 discitis patients were treated by conservatively and the remaining 9 underwent surgery. Among reherniation patients, 58 underwent revision discectomy and 4 underwent transforaminal lumbar interbody fusion and stabilization. Aggressive discectomy is an effective treatment of lumbar disk herniation and maintains a lower incidence of reherniation but leads to a collapse of disc height and in long run gives rise to intervertebral instability and accelerates spondylosis.

The purpose of this study is to compare the periodontal health of the lower anterior teeth retained with the use of removable and fixed retainers. Fifty four cases receiving comprehensive orthodontic treatment in between 10 to 30 years were randomly selected and divided into 2 groups of 27 each. One group was given removable retainers and other was given fixed retainers. The periodontal status of the patients was accessed with bleeding on probing index, Plaque index and Calculus index. The mean plaque index in case of removable retainers at 1st, 3rd and 6th month were 0.5, 1.0 and 1.7 where as in case of fixed retainers that were 1.8, 3.0 and 4.5. The mean dental calculus index in case of removable retainers at 1st, 3rd and 6th month were 0.0, 0.1 and 0.1 where as in case of fixed retainers that were 0.1, 0.9 and 1.8. In conclusion, removable retainers are superior in oral hygiene maintenance, yet the use of fixed retainers cannot be denied.

This randomized controlled clinical trial was conducted to assess the efficacy and safety of intralesional triamcinolone acetonide in the treatment of chronic hand eczema comparing with topical clobetasol propionate. A total 60 patients of chronic hand eczema were recruited in the study. Thirty patients (Group A) were treated with intralesional triamcinolone acetonide and the rest 30 (Group B) with topical clobetasol propionate. Severity and improvement were assessed using Hand Eczema Severity Index (HECSI) score. The patients of both groups were followed up at 4th week and 12th week. In Group A, median HECSI score at baseline, 4th week and 12th week were 3, 20 and 20 respectively; whereas these scores were 54, 10 and 8 in Group B. In both groups, HECSI score was decreased gradually but the rate was higher in Group B than Group A (p<0.05). Thinning of skin, an adverse effect, was seen in patients of both the intralesional triamcinolone acetonide (10%) and topical clobetasol propionate (16.7%) groups (p>0.05). The result of this study demonstrates that intralesional triamcinolone acetonide is effective and safe in treating chronic hand eczema but less effective than the topical clobetasol.

Spondylolisthesis is forward slipping of upper vertebra in relations to its lower one, commonest is L4-L5. The ideal surgical treatment of spondylolisthesis is still controversial. Posterior lumber interbody fusion with pedicle fixation is one of treatment choices for the lumber spondylolisthesis. Forty patients who operated through posterior lumber interbody fusion and pedicle screw fixation by single surgeon was included from January 2012 to March 2015. Periodical follow-up was done both clinically and radiologically up to 6 months. Patient outcome was completed based on pain relief graphic rating scale and Oswestry disability index. In our series, the excellent outcome were 25 patients (62.5%), good were 12 patients (30%), and fair were 3 patients (7.5%). There were no poor outcome and no new neurological deficit. This study concludes that posterior lumber inter-body fusion with pedicle is an effective treatment for the lumber spondylolisthesis. It helps to maintain the biomechanics, associated with less complication and improve the quality of life of patient.

Authors: Zhang Taotao , Zhang Keping , Liu Wende , Liao Yangchao
Published: September 2017

Cement-based piezoelectric composite, has been widely used as a kind of smart material in structural health monitoring and active vibration control. However, transient dynamic loads such as impact loads may cause serious damage to the composite. Considering the electrode layer effect, this paper aimed to investigate the theoretical response of a 2-2 cement-based piezoelectric composite sensor subjected to an impact load. The vibration behaviors are analyzed by using the mode summation method and the virtual work principle. To simulate the impact load, transient haversine wave loads are assumed in the numerical simulation. Close agreements between theoretical and numerical solutions are found for peak transient haversine wave loads larger than 500 kPa, therefore proving the validity of the theory. Moreover, the influence of the electrode material and geometrical parameters on the dynamic characteristics of this sensor are considered. The present work should be beneficial to the design of this kind of sensor by taking into account the electrode layer effect.

Mycoplasma pneumoniae is a common atypical respiratory pathogen causing community-acquired pneumonia in children. Co-infection with other respiratory viruses is common in pediatric patients but super-infection with bacteria other than Streptococcus pneumoniae and Haemophilus influenzae is rare. The first case of Chromobacterium violaceum infection incubated during and manifested after pneumonia caused by Mycoplasma pneumoniae in a 12-month old girl without any known history of immunodeficiency is here reported. The patient developed fever with redness and swelling over the middle phalanx of the right hand index finger which progressed to the formation of skin abscess. Following a course of intravenous meropenem and surgical drainage of the skin abscess, the patient fully recovered and was discharged.

Published: September 2017

The influence of thermal radiation on a two-dimensional non-Newtonian fluid flow past a slendering stretching surface is investigated theoretically. Casson and Williamson fluid models are considered with Soret and Dufour effects. The transformed ODEs are solved numerically using the bvp5c Matlab package and dual solutions are executed for Casson and Williamson fluid cases. The influence of various parameters, namely, thermal radiation parameter, cross diffusion parameters and slip parameters on velocity, thermal and concentration distributions are discussed with the assistance of graphs. The local Nusselt and Sherwood numbers are computed and presented through tables. It is observed that the influence of cross diffusion is higher on Williamson flow when equated with the Casson flow.
Free Multivariate w*-Semicrossed Products: Reflexivity and the Bicommutant Property
Authors: Bickerton Robert T. , Kakariadis Evgenios T. A.
Published: September 2017

We study w*-semicrossed products over actions of the free semigroup and the free abelian semigroup on (possibly non-selfadjoint) w*-closed algebras. We show that they are reflexive when the dynamics are implemented by uniformly bounded families of invertible row operators. Combining with results of Helmer, we derive that w*-semicrossed products of factors (on a separableHilbert space) are reflexive. Furthermore, we show that w*-semicrossed products of automorphic actions on maximal abelian self adjoint algebras are reflexive. In all cases we prove that the w*-semicrossed products have the bicommutant property if and only if the ambient algebra of the dynamics does also.
Homological Dimensions of Local (Co)homology Over Commutative DG-rings
Authors: Shaul Liran
Published: September 2017

Let A be a commutative noetherian ring, let a ⊆ A be an ideal, and let I be an injective A-module. A basic result in the structure theory of injective modules states that the A-module Γa(I) consisting of ɑ-torsion elements is also an injective A-module. Recently, de Jong proved a dual result: If F is a flat A-module, then the ɑ-adic completion of F is also a flat A-module. In this paper we generalize these facts to commutative noetherian DG-rings: let A be a commutative non-positive DG-ring such that H0(A) is a noetherian ring and for each i < 0, the H0(A)-module Hi(A) is finitely generated. Given an ideal ⊆ H0(A), we show that the local cohomology functor R associated with does not increase injective dimension. Dually, the derived -adic completion functor LΛ does not increase flat dimension.
Infinite Powers and Cohen Reals
Authors: Medini Andrea , van Mill Jan , Zdomskyy Lyubomyr
Published: September 2017

We give a consistent example of a zero-dimensional separable metrizable space Z such that every homeomorphism of Zω acts like a permutation of the coordinates almost everywhere. Furthermore, this permutation varies continuously. This shows that a result of Dow and Pearl is sharp, and gives some insight into an open problem of Terada. Our example Z is simply the set of ω1 Cohen reals, viewed as a subspace of 2ω.
A Spectral Identity on Jacobi Polynomials and its Analytic Implications
Authors: Awonusika Richard , Taheri Ali
Published: September 2017

The Jacobi coefficientsare linked to the Maclaurin spectral expansion of the Schwartz kernel of functions of the Laplacian on a compact rank one symmetric space. It is proved that these coefficients can be computed by transforming the even derivatives of the Jacobi polynomialsinto a spectral sum associated with the Jacobi operator. The first few coefficients are explicitly computed, and a direct trace interpretation of the Maclaurin coefficients is presented.

A model for heating and evaporation of mono- and multi-component droplets, based on analytical solutions to the heat transfer and species diffusion equations in the liquid phase, is summarised. The implementation of the model into ANSYS Fluent via User-Defined Functions (UDF) is described. The model is applied to the analysis of pure acetone, ethanol, and mixtures of acetone/ethanol droplet heating/cooling and evaporation. The predictions of the customised version of ANSYS Fluent with the newly implemented UDF model are verified against the results predicted by the previously developed in house, one-dimensional code.DOI: http://dx.doi.org/10.4995/ILASS2017.2017.4759
Investigation on the role of atomization air mixing on the spray characteristics of air assisted atomizer
Authors: Kawaharada Noritsune , Höltermann Markus , Wichmar Jan , Dinkelacker Friedrich
Published: September 2017

Air assisted atomizers are widely used for various purposes, for example coating processes, medical processes, and sprinkler. However, the spray development processes, especially the breakup phenomena are not fully understood yet. Generally, the main breakup of the air assisted atomizer depends on whether the mixing is internal or external. The border between these processes is not clear. In order to study changes in the spray configuration due to the way of mixing, the spray was investigated for the transition from internal to external mixing. Therefore, an air assisted atomizer which allows adjusting the distance between injector to cover was used. The atomizer consists of two components, which are a liquid injector and an injector cover with orifice. The atomization air flows through the gap between the injector and the cover. The position of cover orifice is able to be traversed from the position fully attached to the injector to several millimeter distances from the injector nozzle. In this study, the water spray characteristics depending on the air and liquid mixture position were investigated experimentally by two optical measurement techniques. Phase Doppler Anemometer (PDA) has been applied for measurement of velocity and size of droplets in water spray which injected into the atmosphere. Also, high resolution direct imaging technique has been developed and applied for measurement of size of droplets. The results from these measurement techniques were compared and they correspond well. Imaging techniques were used also for taking the spray angle as well as the liquid core in the near field. The measurement positions were set at planes which are located on various positions downstream from the nozzle orifice. For each downstream position, radial profiles of the spray pattern were measured. The water mass flow, atomization air volume flow, and the cover position are changed and their effects on the spray are characterized. The atomization mass flow and the cover position can be set in a way to design the radial profile of the spray according to the requirement of the process.
Hygroscopic behavior and chemical composition evolution of internally mixed aerosols composed of oxalic acid and ammonium sulfate

Published: September 2017

Abstract. Although water uptake of aerosols plays an important role in the atmospheric environment, the effects of interactions between components on chemical composition and hygroscopicity of aerosols are still not well constrained. The hygroscopic properties and phase transformation of oxalic acid (OA) and mixed particles composed of ammonium sulfate (AS) and OA with different organic to inorganic molar ratios (OIRs) have been investigated by using confocal Raman spectroscopy. It is found that OA droplets first crystallize to form oxalic acid dihydrate at 77 % relative humidity (RH), and further lose crystalline water to convert into anhydrous oxalic acid around 5 % RH during the dehydration process. The deliquescence and efflorescence point for AS is determined to be 80.1 ± 1.5 % RH and 44.3 ± 2.5 % RH, respectively. The observed efflorescence relative humidity (ERH) for mixed OA/AS droplets with OIRs of 1:3, 1:1 and 3:1 is 34.4 ± 2.0 % RH, 44.3 ± 2.5 % RH and 64.4 ± 3.0 % RH, respectively, indicating the elevated OA content appears to favor the crystallization of mixed systems at higher RH. However, the partial deliquescence relative humidity (DRH) for mixed OA/AS particles with OIR of 1:3 and 1:1 is observed to occur at 81.1 ± 1.5 % RH and 77 ± 1.0 % RH, respectively. The Raman spectra of mixed OA/AS droplets indicate the formation of ammonium hydrogen oxalate (NH4HC2O4) and ammonium hydrogen sulfate (NH4HSO4) from interactions between OA and AS in aerosols after slow dehydration process in the time scale of hours, which considerably influence the subsequent deliquescence behavior of internally mixed particles with different OIRs. The mixed OA/AS particles with 3:1 ratio exhibit no deliquescence transition over the RH range studied due to the considerable transformation of (NH4)2SO4 into nonhygroscopic NH4HC2O4. Although the hygroscopic growth of mixed OA/AS droplets is comparable to that of AS or OA at high RH during the dehydration process, Raman growth factors of mixed particles after deliquescence are substantially lower than those of mixed OA/AS droplets during the efflorescence process and further decrease with elevated OA content. The discrepancies for Raman growth factors of mixed OA/AS particles between the dehydration and hydration process at high RH can be attributed to the significant formation of NH4HC2O4 and residual OA, which remain solid at high RH and thus result in less water uptake of mixed particles. These findings improve the understanding of the role of reactions between dicarboxylic acid and inorganic salt in the chemical and physical properties of aerosol particles, and might have important implications for atmospheric chemistry.
Corrective Feedback and Personality Type: A Case Study of Iranian L2 Learners
Authors: Banaruee Hassan , Khoshsima Hooshang , Askari Afsane
Published: September 2017

The aim of this study was to investigate the impact of explicit and implicit corrective feedback on extrovert and introvert language learners in a writing course. Participants were classified into two groups of explicit corrective feedback and implicit corrective feedback. Based on Myers-Briggs personality questionnaire, participants of each group were divided into extroverts and introverts. Throughout a writing course, the first group was provided with explicit feedback and the second group with implicit feedback. The results of a pretest and a posttest showed that while explicit corrective feedback is more effective for extroverts, indirect implicit feedback produces better results for introverts in writing courses. However, it is suggested that an optimal mixture of positive and negative feedback would be most beneficial in writing courses, particularly for extrovert learners who need external stimuli to be pushed forward.

Is Enjoyment Still Important in University Second Language Education?
Authors: Winch Junko
Published: September 2017

This study investigates if undergraduate students majoring in Science, Technology, Engineering and Medicine (STEM) who have studied Japanese in the Institution-Wide Language Provision (IWLP) context experienced enjoyment in Japanese language learning. This research was held at a British STEM university in London. Questionnaires were used to generate the quantitative and qualitative data. The participants were STEM undergraduate students who were studying Japanese in the 2015/16 academic year. The results showed that the majority of students experienced enjoyment and flow in Japanese language learning. These results show that the general assumption that all learning is grim and unpleasant is not necessarily true and that the assumption may be changed. Furthermore, language learning may be considered as the same as a leisure activity such as games, shopping or hobbies. As an implication for professional practices, language teachers are encouraged to be familiar with the concept of enjoyment and flow so that they are able to manipulate to invoke students’ enjoyment and flow.
Conflict Resolution Strategies Observed During Discussions among Students with Different Personalities
Authors: Lin Siew Fong
Published: September 2017

The aim of this study is to obtain insight on conflict resolution strategies during collaborative writing among students with different personality profiles categorised under Leonard Personality Inventory (LPI) in Malaysia. A case study group consisting of five Diploma in Mass Communication students were observed. The research instruments used were video recordings, interviews, diary entries and observations. The findings in this study showed the use of conflict resolution strategies in reducing conflict in the course of collaboration. Consequently, there were mixed results on the group dynamics. The methods in conflict resolution could be divided into collectivist and individualistic approaches. The former were using humour to diffuse tension, filtering ideas and diverting attention from conflict by voluntary involvement in performing sub-tasks. However, the latter were the leader being abrasive towards group members and the group members ignoring leader’s guidance. In addition, it was obvious that some participants behaved according to their personalities consistently while some placed priority on their roles played in the group. It is recommended that self-reflection be encouraged to improve collaboration and guidance on facilitation of groups be provided to group leaders prior to their collaboration.

Published: September 2017

Based on a mixed method research design, this study aims to investigate the effectiveness of applying scaffolding strategies in enhancing reading comprehension skills of female students at King Abdulaziz University in the city of Jeddah in Saudi Arabia. The participants of the study were thirty-three female students at the preparatory year program (PYP) who were registered at the proficiency level 104 (B1/Threshold level on the Common European Framework of reference for language; CEFR). They were divided into two groups: Seventeen students in the control group and sixteen students in the experimental group. Both groups were exposed to the same reading lessons but with the experimental group exposed to scaffolding strategies. Prior to the treatment, a pretest was administered to both groups. Once the treatment was accomplished, a posttest was administered to investigate the effect of applying scaffolding strategies on developing reading comprehension skills. Furthermore, qualitative data was collected via open-ended questionnaire. The results of the study indicated that there was a statistically significant difference between the pretest and posttest of the experimental group in favor of the posttest. Furthermore, students showed a positive attitude to the scaffolding technique as a motivation factor to their learning. Conclusions and recommendations for further research are given at the end of this study.
Thematic Preoccupation of Nigerian Literature: A Critical Approach
Authors: Chris Ajibade Adetuyi,
Published: September 2017

Nigerian literature takes "matter" from the realities of Nigerian living conditions and value systems in the past and present. In the Nigerian society the writer, be it a novelist, dramatist or poet is a sensitive "questioner" and reformer; as all literature in a way is criticism of the human condition obtainable in the society it mirrors. The writer often cannot help exposing the bad and the ugly in man and society. Thus much of Nigerian literature is a deploration of the harsh and inhuman condition in which the majority of Nigerians live in i.e. poverty, misery, political oppression, economic exploitation, excesses of the affluent, liquidation of humane Nigerian traditional values, and all forms of injustices which seem to be the lot of a large majority in most Nigerian societies.In drama, novel, poetry or short - story, the writer's dialogue with his physical and human environment comes out as a mirror in which his people and society can see what they look like. Every image painted by a skillful artist is expressed or put into writing / print, becomes public property and leaves itself open for evaluation by those who read and understand the language and expression. There is therefore a need to identify the thematic preoccupation of Nigeria literature which is the focus of this paper with a view to identifying their peculiarities with textual references.
Exploring the patient experience of chronic illness through literature and film
Authors: Harding Mariann M.
Published: September 2017

Objective: Caring for patients with a chronic illness requires a holistic approach. To help RN-BSN nursing students in a course focusing on chronic illness see the patient as a unique individual and to foster empathy by emphasizing the person behind each patient, literature and film were used to make the patient’s lived experience of chronic illness real.Methods: Students read autobiographies or biographies and viewed film about the patient experience of chronic illness. Materials were selected based on the illness and patient issues described. Using the Socratic Seminar, students prepared questions based on weekly reading assignments; faculty prepared questions for each film, encouraging active participation and group discussion of underlying insights. Many discussions revolved around select film scenes or quotations students selected from the text and the comparison to their practice experience with similar patients in the clinical setting.Results: Satisfaction with the course was overwhelming, with all students rating every evaluative category as a “5”, strongly agreeing that the course advanced their empathy towards patients with chronic illness. Comments detailed students’ having a better understanding of how chronic illness truly affects the patient and family. The books resonated with the class more than the films, as the books had more detail and put the reader into the setting as if they were the person.Conclusions: The use of literature and film is an effective means to enhance RN-BSN nursing students’ ability to understand and empathize with a patient’s needs and was successful in helping students understand the patient experience.

The main aim of this research study is to investigate the clarity and familiarity of three scoring rubrics used in a Saudi university’s preparatory year program (PYP) for assessing students’ writing achievement in midterm and final exams. This exploration is important in providing some evidence for the quality of scoring rubrics. To achieve that purpose, a 13-item online questionnaire was used to collect Saudi EFL PYP students’ perspectives toward two quality criteria concerning rubrics; 1) clarity of the information included in the PYP rubrics, and (2) familiarity of the rubrics to students. The subjects were 281 Arabic-speaking male and female EFL Saudi students enrolled in three different academic levels in a Saudi university’s PYP. The results suggest that the quality of the PYP rubrics is insufficient and the criteria set for providing evidence for the rubric qualities were not met. The results show that students tend to have a mild agreement on the clarity of the PYP rubrics, whereas they show a clear disagreement on their familiarity with the rubrics and with why and how the rubrics are used. The study implicates that administrators and teachers need to carefully consider the clarity and familiarity of rubrics in order to justify the decisions made about students’ writing abilities. Rubrics that are unclear or unfamiliar can make students feel confused and frustrated, as they cannot get a clear sense of their writing scores, as well as their strengths and weaknesses.

Online teaching and learning became popular with the evolution of the World Wide Web now days. Implementing online learning tools within EFL contexts will help better address the multitude of teaching and learning styles. Difficulty in academic writing can be considered one of the common problems that students face in and outside their classrooms. Moreover, because the young learners today are digital native, integrating online learning tool with their learning is needed. This research was conducted to analyze students’ achievements by submitted tasks using both face-to-face setting for the pre individual and collaborative tasks, and online learning environment for the post individual and collaborative tasks. The participants in this study were a class of Arabic major from a college in Saudi Arabia. The research was searching for the differences between the students’ individual and collaborative work using Google Docs, and discerning the students’ perspectives toward collaborative work with Google Docs on English writing tasks. To explore the integration effectiveness; pre and post-questionnaires, pre and post written tasks, students’ portfolio, a customized rubric for test scores, and post interviews were conducted to test and analyze the outcomes. Results show significant increase in the students’ scores using Google Docs. Further, the results were consistent as that students perceived Google Docs as a useful tool for both individual and group work.
Critical Thinking and Argumentative Writing: Inspecting the Association among EFL Learners in China

Nurturing critical thinking (CT) has been acknowledged as a core objective of tertiary education, and drawn attention from academia of teaching English as a Foreign Language (EFL) in China. The thrust of the present study was to determine the association between CT and EFL argumentative writing among Chinese undergraduates. To this end, 110 English majors across three grades at two universities were conveniently selected and given the critical thinking skills (CTS) test and EFL argumentative writing test. The results of this study indicated that undergraduate English majors in China did not possess strong CTS. Though their CTS was not found to be significantly correlated with EFL argumentative writing performance, textual analysis of typical essays showed that strong-CTS learners outperformed weak-CTS ones in relevance, clarity, logicality, profundity and flexibility of argumentative writing. The obtained results suggest a need to integrate CT into EFL writing instruction.

Mineralogical and Geochemical Trends in the Residual Soils above Basement Rocks in Ore Area, Southwestern Nigeria
Authors: Adeola Adewole John , Tubonemi Emmanuel Tamunobelema
Published: September 2017

Residual clays and laterite of economic values often occur within weathering profiles above basement rocks in tropical regions due to supergene enrichment and leaching of liable components. Previous studies in Ore area mainly on geochemistry of the basement rocks with scanty information on the weathered profiles. This study was carried out to determine the compositional characteristics of the basement rocks, the geochemical trends within the profiles above the parent rocks and the evaluation of their economic potentials.Petrographic study was carried out on thin sections of the rock samples. Elemental compositions of the rocks, clay, laterite, and top-soil were determined using Inductively Coupled Plasma-Mass Spectrometer (ICP-MS). Clay mineralogy was determined using X-ray Diffraction (XRD) analysis. Chemical index of Alterations (CIA) was calculated from geochemical data.Weathering of granite and banded gneiss in Ore resulted in the formation of soil layer, which ranged 0-0.5m, laterite 1.2-3m and clayey zone 2.9-3.0m. Quartz, plagioclase feldspars, microcline, biotite and hornblende were the essential minerals in the parent rocks. Granite and banded gneiss is high SiO2 (>65%) but low in MgO (<2.0%) and CaO (<4.0%). Kaolinite (60-80%), goethite (3-12%) and microcline (4-10%) were the dominant minerals in the XRD of the weathering profiles. Traces of illite were present only in granite. The CIA was generally > 85 indicating advanced state of weathering producing lateritic soil. The lateritic profiles over granite and banded gneiss of Ore area varied with the composition of the parent rocks. The clay layer has economic potential for ceramics, fertilizer and structural wares.

PROJECTS FROM THE AREA OF DIGITISATION
AND NEW MEDIA IN THE SYBILLA CONTEST
Authors: Górka Jacek
Published: September 2017

The dynamics of the social, economic and legal
changes which took place from 2004 to 2014 related to
Poland’s accession to the European Union has changed our
reality and the functioning of the state and its institutions,
including museums. New possibilities have arisen, together
with serious challenges which museum managers and museum
professionals have had to face.
The National Institute for Museums and Public Collections,
established in 2011, has become the organiser of the prestigious
Sybilla Museum of the Year Contest, in line with its
founding principles. Its organisers decided to carry out open
consultations with museum professionals, which has resulted
in changes to the regulations for new contest categories,
pertaining for example to sources of financing an institution
with European funds, and implementing new technological
solutions by museums. The growing availability of new technologies
has contributed to a new category in the contest
“Digitisation and new media”, which appeared for the first
time in the regulations for the 34th edition of the Sybilla contest
in 2013.
The process of technological revolution also applies to
museums, as new technologies are present at museum
conservation workshops, research papers, exhibition premises
and educational activities. Museums use diverse electronic
communication solutions, such as websites, applications
and social media. Digital technologies are being used
on an unprecedented hitherto scale to document and share
collections, and to disseminate knowledge about them.
During the latest, 37th edition of the Sybilla contest in
2016, a unique project was awarded: the Gulf of Gdańsk
Shipwreck Virtual Open-Air Museum. Recording and
Inventory of Underwater Archaeological Heritage, carried
out by the National Maritime Museum in Gdańsk. An innovative
method for submarine documentation, in the form
of the photogrammetry of 3D models of shipwrecks from
the Gulf of Gdańsk, is being developed as part of the project.
Faras in Wikipedia is a featured project by the National
Museum in Warsaw. It consists of creating a knowledge database
about the Faras Gallery, about the relics of Nubian
art which form part of the museum’s collections, and the archaeological
expedition and researchers involved, as well as
making it available to the readers of Wikipedia and Internet
users in Poland and abroad.
THE ROMA COLLECTION KNOWN AS THE AMARO
MUSEUM
Authors: Gancarz Natalia
Published: September 2017

The first significant exhibition devoted to Roma/
Gypsy history and culture was organised in the Regional
Museum in Tarnów in 1979. After its success, collections
connected with the history of this ethnic group were initiated.
The Ethnographic Museum in Tarnów (the branch of the
Regional Museum) opened a permanent exhibition entitled
“Gypsies. History and culture” as the first permanent museum
exhibition devoted to Roma matters in 1990. The Gypsy
collections of the museum amount to almost 1000 exhibits;
moreover, it gathers professional photographic, cinematographic
and phonographic documentation and archives, and
it runs a specialised library.
Based on this permanent Roma exhibition and collections,
the museum in Tarnów organises numerous cultural
and educational projects, as well as those that promote
Roma culture and history. The International Roma Caravan
Memorial is a regular event which has been organised since
1996. It is a project which consists in a kind of a reconstruction
of a Gypsy wandering caravan, during which the
participants visit places connected with Roma martyrdom
during the Second World War in Małopolska. In addition,
the museum publishes a scientific annual entitled “Studia
Romologica”.
