Authors: Tašner Marina , Mrvoš-Sermek Draginja , Hajdarpašić Emina , Matković-Čalogović Dubravka
Published: December 2018

A new dinuclear paddle-wheel copper(II) complex with caffeine was synthesized by the solvent-based and mechanochemical methods from copper(II) acetate and caffeine in a 1:1 molar ratio. Mechanochemical synthesis was found to be the fastest and easiest way to prepare the complex. The reaction proceeds with addition of small amounts of methanol or ethanol. The complex was characterized by FT-IR spectroscopy, elemental and thermoanalytical methods (TG and DSC) and X-ray diffraction methods. The molecular and crystal structure was determined by the single crystal X-ray diffraction method. The complex molecule consists of a centrosymmetric dinuclear unit, Cu2(-Ac)4(caf)2, with two copper(II) atoms bridged by four acetato groups, and N-coordinated caffeine (caf) molecules in the apical posi-tions.

HISTOCHEMICAL EVALUATION OF IRON CONTENT IN THE LIVER OF WILD FEMALE OHRID TROUT (SALMO LETNICA KAR.) ALONG THE BREEDING CYCLE
Authors: Jordanova Maja Jordanova , Rebok Katerina , João Rocha Maria , Rocha Eduardo
Published: December 2018

Iron is an essential micronutrient for the normal metabolism of all cells. Intracellular iron varies within normality ranges, and depletion or overload of brings serious consequences. As such, iron can also be deleterious when appearing as an environmental toxicant. The aim of this study was to estimate semi-quantitatively the liver iron content in female Ohrid trout, from the Lake Ohrid, during the breeding cycle. Seasonal variations in hepatocytic iron were observed. The maximum content occurred at post-spawning, which was significantly higher than loads detected at pre- and early-vitellogenesis. Positive correlations existed between iron amounts and stages of ovary maturation. By the contrary, there were no correlations between iron contents and plasma oestradiol levels. The new uncovered "iron-breeding associa-tion" strongly endorses that normal seasonal variations in hepatocytic iron content should be taken into consideration in field studies investigating and monitoring the metal burden and toxicological effects of metals on wild fish.

Published: December 2018

The objective of this work is to evaluate the impact of the innovative modifications made to the conventional effluent capture and discharge devices used in subsurface flow wetlands (SSFW). The main modifications developed consist on extending the influence of the capture and discharge device in such a way that the SSFW width and height are fully covered. This improved innovative device was applied and evaluated in two subsurface flow wetlands, one on a pilot scale and one on a real scale. To evaluate the impact of the innovative device with respect to conventional one in the operational functioning of subsurface flow wetlands, the elimination of chemical oxygen demand was measured and compared. The results show that for the innovative device, the COD removal was 10% higher than for the conventional device, confirming the validity and effectiveness of the modifications implemented in the effluent capture and discharge devices used in SSFW.

Published: December 2018

In many regions where drinking water supply is intermittent and unreliable, households adapt by storing water in cisterns or rooftop tanks. Both intermittent supply and stored water can be vulnerable to contamination by microorganisms with deleterious health effects. The Guadalajara Metropolitan Area is a rapidly growing urban center with over five million residents where household storage is nearly ubiquitous. This pilot study was conducted in July 2018 to examine the microbiological quality of drinking water in Guadalajara. Samples were tested for free available chlorine residual, total coliform bacteria, and E. coli. A survey on access to water and public perspectives was also conducted. Water exiting rooftop tanks exceeded regulatory limits for total coliform levels in half of the homes studied. Piped water arriving at two homes had total coliform levels that far exceeded regulatory limits. No E. coli were detected in any of the samples. Only 35% of homes had a chlorine residual between the recommended 0.2 and 1.5 mg/L. Many homes reported unpleasant odors and colors. Only 7% of residents drank the piped water. Future studies are needed, especially during April and May when many homes reported a higher disruption to water service.

Published: December 2018

Atopic dermatitis (AD) is a chronic cutaneous inflammatory disorder, characterized by skin barrier disruption. Dermacare is a new cosmetic formulation which enhances moisturization, reinforces and repairs the skin barrier and prevents cutaneous microbiota imbalance. To demonstrate its safety and efficacy a prospective, open-label and multicenter study was carried out on patients diagnosed with mild to moderate AD. Transepidermal water loss (TEWL), clinical severity, Desquamation Index, Patient/Investigator Global Assessments, quality of life index and tolerance were assessed. Adverse events were recorded. Daily application of the new treatment was well tolerated, and adverse events were absent. After 14 days, TEWL showed a 36.7% significant decrease (p = 0.035). At the end of the 28-day Dermacare treatment, the Desquamation Index showed a reduction in 70% of patients; Eczema Area and Severity Index were reduced by 70.4% (p = 0.002); and skin irritation showed a significant reduction (p = 0.024). Likewise, Patient and Investigator Global Assessments reported a significant improvement in conditions and an overall global worsening when patients restarted their normal treatment. Parent’s Index of Quality of Life Index significantly increased by 36.4% (p < 0.05) with Dermacare. In conclusion, Dermacare’s regular use helped reduce the risk of relapse and extend the steroid-free treatment periods.
Deep Convolutional Neural Network Applied on Copper Surface Coatings Based on Polyvinyl Alcohol and Silver Nanoparticles

Published: December 2018

In order to design effective protective coatings against corrosion, the polyvinyl alcohol (PVA) as compound and composite with silver nanoparticles (nAg/PVA) were electrodeposited on copper surface employing electrochemical techniques such as linear potentiometry and cyclic voltammetry. A new paradigm was used to distinguish the features of coatings, i.e., a Deep Convolutional Neural Network (CNN) was implemented to automatically and hierarchically extract the discriminative characteristics from the information given by optical microscopy images. The main arguments that invoke a CNN implementation in the surface science of materials are the following: artificial intelligence techniques can be successfully applied to learn differences between surface coatings; based on their popularity for image processing, CNN can model images related to the problem of coatings; deep learning is able to extract the features that are distinguishable between material surfaces. To provide an overview of the copper surface, CNN was applied on microscope slides (CNN@microscopy) and inherently learnt distinctive characteristics for each class of surface morphology. The material surface morphology controlled by CNN without the interference of the human factor was successfully conducted, in our study, to extract the similarities/differences between unprotected and protected surfaces to establish the PVA and nAg/PVA performance to retard the copper corrosion.
Gravitation: Immediate Action at a Distance or Close Up Events?
Authors: Hollestelle Harmen Henricus
Published: December 2018

Is immediate action at a distance, like gravitational attraction, imaginable using the contrary concept of close up, tactile, events? Tactile events, defined with the term ‘tap-tapping’ as a blind man does, described in a two-way spiritual interaction theory, are implemented in physics to understand gravitation from this respect. The quantum mechanical wave function reduction during measurements receives a new approach. Formulated is a new proof for Einstein’s Equivalence Principle, extending it beyond locality, and a sketch of how tactile interaction could explain dark energy and an accelerated expansion of the universe. Dark energy and dark matter are examples starting from which to discuss properties of matter and space and gravitation as immediate tactile action rather than mediated action such as electromagnetism.
The Rise of English as the Language for Academic Publication: On Equity, Disadvantage and ‘Non-Nativeness’ as a Red Herring
Authors: Hultgren Anna Kristina
Published: December 2018

Within the fields of English for Academic Purposes (EAP) and English for Research Publication Purposes (ERPP), there is an unquestioned orthodoxy that scholars with English as an Additional Language (EAL) are particularly disadvantaged by the pressure to publish in English (though see Kuteeva 2015 and debate between Hyland 2016a, 2016b and Politzer-Ahlesa et al. 2016). In this paper, I challenge this orthodoxy, raising questions about the evidence upon which it is based. Within a framework of ‘verbal hygiene’ (Cameron 1995, 2012), I will argue that the attention accorded to ‘non-nativeness’ may be disproportionate to its significance for publication success. I conclude by proposing some reorientations for researchers and practitioners in the field that centre on broadening the scope to encompass non-linguistic structures of inequity.
Measuring Canopy Structure and Condition Using Multi-Spectral UAS Imagery in a Horticultural Environment
Authors: Tu Yu-Hsuan , Johansen Kasper , Phinn Stuart , Robson Andrew
Published: December 2018

Tree condition, pruning and orchard management practices within intensive horticultural tree crop systems can be determined via measurements of tree structure. Multi-spectral imagery acquired from an unmanned aerial system (UAS) has been demonstrated as an accurate and efficient platform for measuring various tree structural attributes, but research in complex horticultural environments has been limited. This research established a methodology for accurately estimating tree crown height, extent, plant projective cover (PPC) and condition of avocado tree crops, from a UAS platform. Individual tree crowns were delineated using object-based image analysis. In comparison to field measured canopy heights, an image-derived canopy height model provided a coefficient of determination (R2) of 0.65 and relative root mean squared error of 6%. Tree crown length perpendicular to the hedgerow was accurately mapped. PPC was measured using spectral and textural image information and produced an R2 value of 0.62 against field data. A random forest classifier was applied to assign tree condition into four categories in accordance with industry standards, producing out-of-bag accuracies >96%. Our results demonstrate the potential of UAS-based mapping for the provision of information to support the horticulture industry and facilitate orchard-based assessment and management.
Probing Globular Proteins Self-Assembling Dynamics by Heterodyne Transient Grating Experiments
Authors: Catalini Sara , Taschin Andrea , Bartolini Paolo , Foggi Paolo , Torre Renato
Published: December 2018

In this work, we have studied the propagation of ultrasonic waves of lysozyme solutions characterized by different degrees of aggregation and networking. The experimental investigation has been performed by means of the Transient Grating (TG) spectroscopy as a function of temperature; this technique enables to measure the ultrasonic acoustic proprieties over a wide time window, ranging from nanoseconds to milliseconds. The fitting of the measured TG signal allows the extraction of several dynamic properties, here we focused on the speed and the damping rate of sound. The temperature variation induces in the lysozyme solutions a series of processes: protein folding-unfolding, aggregation and sol-gel transition. Our TG investigation shows how these self-assembling phenomena modulate the sound propagation, affecting both the velocity and the damping rate of the ultrasonic waves. In particular, the damping of ultrasonic acoustic waves proves to be a dynamic property very sensitive to the protein conformational rearrangements and aggregation processes.

Published: December 2018

As novel materials for carbon capture, phase change solvents can separate into two immiscible phases during the CO2 capturing procedure under a certain temperature. The solvent systems can significantly decrease the energy consumption since the solvents can be regenerated by only heating the rich-CO2 phase. In this work, amino acid ionic liquids (AAILs) were synthesized using quaternary ammonium salts and amino acids as raw materials, and the aqueous solutions were prepared as novel liquid-solid phase change solvents. The results showed that the solvents had excellent CO2 absorption capacity, and the AAILs functionalized by glycine and tryptophan exhibited significant phase change properties. The mechanism of phase-change of the solvent were mainly due to the lower solubility of the product after reaction between AAILs and CO2. The solvent with tryptophan as anion could be regenerated by only heating the CO2-riched solid phase, which might significantly decrease energy consumption of regeneration. And the absorbent could be reused with the regenerated absorption ratio up to 79%. The solvent system has great potential in industrial application due to the easy operation process and efficient recycling ability.

Authors: He Yongming , Pei Yulong
Published: December 2018

In order to evaluate the economy of superhighway, on the basis of the analysis of the cost of the ordinary expressway and high speed railway, the cost of superhighway is estimated. On this basis, the standard of the toll of superhighway at all levels is determined by reference to the standard of the construction cost and the toll collection standard of the ordinary expressway. According to the toll collection standard of superhighway and the fuel consumption cost of superhighway at all levels, the cost of single car and the single person cost of superhighway are calculated. Based on the analysis of highway passenger transport, railway passenger transport and civil aviation ticket price, the single person cost per kilometer of the above travel modes is calculated and compared with the single person travel cost per kilometer of superhighway. The results show that the single person cost of superhighway is between 0.29 and 0.47 yuan /km, which is 0.28 yuan /km higher than the highway bus, 0.18 yuan /km higher than the ordinary expressway self driving and 0.23 yuan /km higher than the express train, but 0.78 yuan/km lower than that of the first class seat of high-speed train, and is 0.92 yuan/km far lower than that of civil aviation flight economy class and 2.42 yuan/km lower than the business class. Therefore, the superhighway trip has certain advantages in economy.

Dynamic Ischiofemoral Impingement: Case-Based Evidence of Progressive Pathophysiology from Hip Abductor Insufficiency
Authors: DiSciullo Alexander A. , Stelzer John W. , Martin Scott D.
Published: December 2018

Case:

We describe 2 patients with no historical, examination, or imaging evidence of ischiofemoral impingement; they both developed hip abductor insufficiency and subsequent ischiofemoral impingement with progression that was confirmed by examination and advanced imaging.

Conclusion:

Hip abductor insufficiency may lead to dynamic progressive ischiofemoral impingement. Hemipelvic instability from hip abductor weakness results in a Trendelenburg gait, narrowing the ischiofemoral space and impinging the quadratus femoris muscle. Treatment options for dynamic ischiofemoral impingement potentially can focus on treatment of the underlying cause of the hemipelvic instability, preventing additional ischiofemoral-space narrowing and quadratus femoris damage by minimizing the Trendelenburg gait.

Coarctation of the aorta is a well-studied congenital heart disease. Our understanding of this congenital heart disease evolves every year from simple obstructive aortic lesions to systemic dysfunction of the cardiovascular system. In the past two decades, there has been a progressive decrease in mortality and early postoperative complications of newborns and infants with aortic coarctation. However, these patients with coarctation of aorta have a high risk of postoperative complications in the long-term period, despite successful correction at an early age. This review will focus on the issues mainly related to blood pressure. Arterial hypertension has been reported to occur in up to 90% of patients, and is considered as the main cause of premature cardiovascular diseases. The development of arterial hypertension in patients after correction of aortic coarctation is likely to be multifactorial and may be associated with the changes in elastic properties of the aorta wall, presence of residual obstruction, changes in the aortic arch geometry, immune-inflammatory disorders and changes in the regulation of renin-angiotensin and baroreceptors. Also described are the prevalence and pathophysiology of arterial hypertension in children who have undergone aortic coarctation repair. Due attention is given to the issues of accurate blood pressure measurement at an early stage of arterial hypertension. Although the patterns for diagnostics of arterial hypertension in adults are well established, we highlight the issues of premature cardiovascular events development in children and describe the techniques, which help provide complementary information for cardiovascular assessment in this group of patients.

Aim. The study aimed to evaluate the size of pulmonary arteries in patients with tetralogy of Fallot during preoperative and intraoperative stages and to find out the influence of preoperative sizes on the surgical management.
Methods. Between January 2015 and May 2018, 50 patients with tetralogy of Fallot younger seven months underwent primary complete or palliative repair. The data obtained from patients' files and include echocardiography, computed tomography and surgical reports. Dimensions of right and left pulmonary arteries were analyzed by calculating the Z-score and Nakata indices.
Results. Z-scores of the left and right pulmonary arteries were significantly smaller by echocardiography comparing to computed tomography (p<0.01). Z-scores of left and right pulmonary arteries measuring by computed tomography were also smaller than the size measured during surgery (p=0.05). Nakata index according to computed tomography was significantly smaller (p<0.05) than this index calculated from surgical reports.
Conclusion. In patients with tetralogy of Fallot, the size of pulmonary arteries according to the visualization methods is smaller than size measured during surgery. Intraoperative sizing of pulmonary arteries could influence surgical management, expanding indications for complete repair in some patients.

Published: December 2018

Background. It was shown earlier that high-density lipoproteins of rat blood plasma increased the frequency and strength of contraction of an isolated rat heart. The main protein component of high-density lipoproteins, apolipoprotein A-I, isolated from human blood plasma, increased the force of cardiac contractions, with little effect on the frequency. A method for obtaining recombinant apolipoprotein A-I developed at the Institute of Biochemistry allows for facilitating the research into cardiotropic properties of this protein.Aim. The purpose of this experiment was to study the effect of recombinant apolipoprotein A-I on the performance of an isolated rat heart and to compare it with the action of native apolipoprotein A-I.Methods. The experiment was performed on Wistar male rats weighing 230–250 g. Isolated hearts of the rats were routinely perfused retrograde, and isovolume pressure in the left ventricle was measured. Recombinant apolipoprotein A-I was obtained in E. coli cells in the form of a chimeric polypeptide followed by the conversion of protein into a mature form of recombinant apolipoprotein A-I.Results. It was shown that recombinant apolipoprotein A-I with a concentration of 20 μg/ml caused a stable increase in pressure in the left ventricle, while the magnitude of the coronary flow and heart rate changed insignificantly. The maximum inotropic effect was registered for 20 min from the beginning of perfusion and amounted to 147.5% relative to the reference values. It was found out that in the presence of recombinant apolipoprotein A-I, the maximum rate of contraction of the left ventricle increased. At the same time, the diastole had a tendency to increase and was larger in comparison with the initial data at 10 and 20 minutes of perfusion.Conclusion. The recombinant apolipoprotein A-I under study has cardiotonic properties similar to its native form. However, the mechanism for implementing the inotropic effect requires further study.Received 3 September 2018. Revised 8 October 2018.

Aim. The aim of this study was to compare the antimicrobial activity of six different solutions: a cocktail of antibiotics, chlorhexidine in two concentrations (0.05% and 0.2%), glycerol, a mixture of glycerin and ethanol, and a commercial decontamination solution “Optiphen”. In addition, we evaluated the influence of these solutions on the mechanical properties (tensile strength and Young's modulus) of the vascular wall during 50 days of storage.Methods. Samples of porcine aortas were stored in the solutions under study for 50 days. Microbiological analysis of the samples was carried out every 10 days. The elastic modulus and tensile strength were determined by uniaxial measurements using a tensile testing machine ESM301 (MARK-10, USA) at 10, 30, and 50 days of the experiment.Results. Microbiological analysis has demonstrated that the samples stored in solution “Optiphen” and chlorhexidine 0.2% were sterile throughout the experiment (50 days). When stored in the cocktail of antibiotics, the samples remained sterile for 40 days. The solution of chlorhexidine 0.05% and glycerol had no required disinfecting properties. Biomechanical properties were the least affected by storage in solution “Optiphen”, and were the most affected by storage in chlorhexidine 0.2%.Conclusion. Microbiological analysis and the study of biomechanical properties have demonstrated that the most suitable solution for long-term storage of vessels without cryoconservation was solution “Optiphen”. However, a detailed morphological analysis of the vascular wall samples is required at different storage times and after subcutaneous implantation in rats, for the final choice of the optimal storage medium.

PROVISION OF GREEN SPACES IN MALAYSIAN PRIMARY SCHOOLS: ISSUES, GUIDELINES AND RECOMMENDATION
Authors: Aziz Nor Fadzila , Said Ismail
Published: December 2018

The provision of conducive learning environments in schools is important in determining the effectiveness of the curriculum and co-curriculum implementation, as well as enriching children’s outdoor play and environmental learning. However, the development of green spaces within school compound is not a priority in Malaysian schools. This paper aims to explore the issues related to the provision of green spaces in Malaysian national primary schools. There are various green spaces that can be provided in school setting such as field, pocket spaces, soft and hard play areas, and animal life, which serves different purposes for children’s activities. Though, the limited budget and the lack of knowledge and design guidelines are among the obstacles encountered by Malaysian schools in developing functional green spaces that provide learning opportunities for children. A greater effort is needed in helping the schools developing their green spaces in terms of funding, expert knowledge and community support.
SPATIAL REGENERATION OF MUSLIM BURIAL PRACTICES IN THE METROPOLITAN AREAS OF KUALA LUMPUR AND JAKARTA
Authors: Mohamed Afla Mohamad Reza
Published: December 2018

This article focuses on the subject of burial practices which are performed by the Muslim population and the management at public cemeteries within the metropolitan areas of Kuala Lumpur and Jakarta. This research examines specifically, the conventional way of burial practice by the majority of the Muslim population. Unlike other major religions in Southeast Asia which are more open and flexible in the disposal of corpses, full body burial is mandatory in Islam. In response to the escalating issue of lack of space and land shortage for Muslim cemetery, local authorities of the two metropolitan areas have identified alternatives and solutions in handling these alarming situations. This research has recognised factors that lead to these problems, as well as discussing available methods to overcome these issues. The finding exhibits Muslim cemetery’s layout to be problematic due to abundance of burial practices accumulated by patrons which led to disorganisation of space and claustrophobia. This article concludes by providing proposals and design guidelines at the terrain level, together with recommendations that emphasise the long-term usage of the grave plots.

Authors: Azmee Muhammad Ikmal Ariff , Osmadi Atasya
Published: December 2018

Lynas Advanced Materials Plant (LAMP) is situated in Gebeng industrial estate in Kuantan, Malaysia. Lynas plant processes rare earth elements that was trucked from Mt Weld Western Australia’s mine site to Fremantle Port and then brought to Malaysia. Rare elements are important in greenhouse emission reduction especially for their distinctive use in wind turbines, hybrid vehicles, automotive chemical action converters and others technologies. However, the construction and the opening of Lynas plant may have caused pollution to the environment and health risk towards surrounding area. Few case studies highlighted the negative impacts of radioactive element towards the surrounding housing market price. Using before-and-after analysis and sensitivity analysis, this research seeks to evaluate the impact from Lynas plant on the price of housing (single storey terrace) in its surrounding area. The findings show that Lynas plant could be one of the factors that have affected the housing market price in the area. This research concludes that, in general, there is an increase of house price after the opening of Lynas plant, however it is evident that there is a trend of increasing house price when the house is farther away from the plant. It is hoped that the findings of this research helps in answering some of the public speculations regarding the impact of the plant.
