DEVELOPMENT OF AN OPTICS INTEREST AND EXPERIENCE SCALE (OIES) AND EXPLORING GENDER DIFFERENCES IN PROSPECTIVE TEACHERS’ INTEREST AND EXPERIENCE
Authors: Kaltakci-Gurel Derya
Published: January 2019

In this research, the development of the Optics Interest and Experience Scale (OIES) was discussed in the first stage, and the gender differences of prospective teachers in their interest and experience were explored with OIES in the second stage. The data were collected from 228 prospective teachers from eleven universities in Turkey. For content and face validity, a theoretical framework for the OIES was established by a detailed literature review and expert opinions were consulted. For the construct validity, the principal component factor analysis was used. The final form of the scale was composed of 33 items and had two main factors namely: ‘experience’and ‘interest’. A reliability analysis of the instrument revealed Cronbach-Alpha coefficients of .906 for the whole scale, .886 for the experience factor, .851 for the interest factor. MANOVA analysis was conducted to explore gender differences in interest and experience scores of prospective teachers in geometrical optics. There was a statistically significant difference between males and females on the combined dependent variables. When the results for the dependent variables were considered separately, the only difference to reach statistical significance was experience such that females reported slightly higher experience in geometrical optics than males. Keywords: scale development, gender differences, interest, experience, geometrical optics.

Rubiana et al, 2018. The Assessment of  Insect Diversity and Community Structure in the Former Area of Coal Mining Reclamation in Muaro Jambi District, Jambi Province. JLSO 7(1): Recovery of land and ecosystems in the form of reclamation is expected to restore lost biodiversity. The success of reclamation can be seen from the recovery of ecosystems and biodiversity in it. However, the study of biodiversity on reclaimed land in Indonesia is still limited to vegetation and has not seen groups of animals especially insects. Insects have a very important functional role in the ecosystem, therefore they can be used as objects of diversity studies in the reclamation area. This study aimed to study the diversity and functional role of insects in the reclamation area. The study was conducted in the reclamation area of a former coal mine in Muaro Jambi Regency. The study area consisted of two different revegetation ages and two different plants. The method of insect collection is by installing pitfall traps with five replications for 2 x 24 hours. The insects were collected from the pitfall trap then identified to the morphospecies level. The results showed that most of the Coleoptera, Diptera, Hymenoptera and Othroptera insects were found in the reclamation area. Insect diversity is influenced by the age of reclamation. One year of reclamation had a lower species than insect age of two years. Based on the results of the analysis show that the composition of insect species showed differences at different reclamation ages. The older the age of reclamation, the composition of insect species tended to resemble the composition of insect species in the forest.

A didelphys uterus also known as a “double uterus” is one of the least common Mullerian duct anomalies. Uterine didelphys is a congenital malformation that result from complete failure of fusion of the ipsilateral Mullerian duct during embryonic development. Ideally, diagnosis should be made before pregnancy and labour to prevent adverse outcomes. Here reporting a case who was a 19 years old, 4thgravida, Para: 0+3 (Spontaneous abortion) referred to Bangabandhu Memorial Hospital (BBMH) USTC, Chittagong at 35 weeks of pregnancy with severe abdominal pain by local physician from Raozan, Chittagong. On vaginal examination a longitudinal vaginal septum and two vagina were found. Uterine Didelphys was confirmed during emergency caesarean section and delivered 1.5 kg male baby with APGAR score 7/10 and was referred to Neonatal Intensive Care Unit (NICU). Post operative recovery of the mother was uneventful. The baby was also discharged at the age of seven days with establishment of breast feeding. To avoid delayed diagnosis and associated adverse outcome clinicians should have high index of suspicion of uterine anomaly when assessing cases of dysfunctional labour.

Paradigma Universal dan Sistem Dunia Islam
Authors: Badi' Ahmad
Published: January 2019

Kajian tentang ekonomi Islam selalu menjadi hal menarik, karena konsep ekonomi Islam sebagai “jalan tengah” antara sistem ekonomi kapitalis dan sosialis. Dalam konteks sosial-ekonomi, ajaran Islam bersifat dinamis serta keberpihakannya pada keadilan sosial bersifat mutlak. Hal ini karena ketidakadilan bisa merusak tatanan sosial serta bertentangan dengan moralitas. Ajaran Islam tentang ekonomi merupakan bagian dari visi besarnya tentang etika universal. Islam menegaskan pentingnya refleksi keimanan,  etika pada motivasi ekonomi manusia. Paradigma dalam ekonomi Islam menjadi penting sebagai landasan berfikir yang dijadikan model atau pola serta menjadi acuan dalam proses penelitian. Profesor Masudul Alam Choudhury adalah salah satu dari segelintir ulama akademik di bidang Ekonomi dan Keuangan Islam yang karyanya telah diakui di kedua Barat serta kalangan akademisi Muslim sebagai memainkan peran berpengaruh dalam menentukan disiplin Islamic Finance & Ekonomi. Paradigma universal menyajikan dunia sistem baru, baik secara konsep maupun aplikasi, lembaga serta masa depan yang berkelanjutan atau kesatuan hukum ilahi, yang disebut sebagai tauhid. Ekonomi, Keuangan, Masyarakat dan Science adalah sub-sistem dari komplementariti dalam sistem-dunia dalam tatanan Tawhidi String Relation (TSR). Masing-masing berinteraksi dalam mekanisme pembelajaran satu dengan yang lain, untuk mewujudkan sistem yang menyeluruh, yang sesuai dengan aturan-aturan dan instrumen-instrumen yang berasal dari epistemologi Tawhid.

kapsamında İstanbul ili Çekmeköy, Sancaktepe, Ümraniye, Kartal ilçelerinde
bulunan farklı okul türlerinde görev yapan 15 okul müdürü ile görüşülmüştür.
Görüşmeler sonucunda elde edilen veriler nitel araştırma yöntemleri
doğrultusunda kodlanarak temalar altında toplanmış ve içerik analizine tabi
tutulmuştur. Araştırma bulgularına göre okul müdürlerinin büyük çoğunluğu üst
yönetim kademelerine, öğrenci velilerine ve öğretmenlere çeşitli ortamlarda ve
çeşitli yöntemlerle hesap vermektedirler. Bununla birlikte okul müdürlerinin
büyük çoğunluğu mali, akademik başarı ve eğitim öğretim alanında hesap
verdiklerini belirtmişlerdir. Okul müdürlerinin büyük çoğunluğu, üst yönetim
kademelerinin hesap vermemesinin, çeşitli şikâyet hatlarının, mevzuat ve
yönetmeliklerin yetersiz olmasının, okulların mali durumlarının farklı
olmasının hesap vermede eşitsizliğe neden olduğunu ifade etmişlerdir.  Aynı zamanda sadece okul yöneticileri ve
öğretmenlerin hesap vermesinin, okulların çevre şartlarının farklı olmasının,
fiziki donanımsal yetersizliklerin, öğretmen niteliği ve performansındaki
farklılıkların okul ve okul yönetimi açısından hesap vermede eşitsizlik
yarattığını belirtmişlerdir. Türkiye bağlamında denetimsel süreçlerin yoğun ve
katı uygulanması, hiyerarşik düzenlemelerin ve anlayışların baskın olması sebebiyle
daha çok üst yönetim birimlerine hesap verilmesi, ülkemiz açısından yapısal ve
kültürel sürecin hesapverebilirliğe yansıması olarak düşünülebilir. Bununla
birlikte okulların çevre şartlarının, veli-öğrenci sosyo ekonomik durumlarının,
okulların fiziksel, donanımsal, mali ve personel özellikleri, nitelikleri,
farklılıkları ve eksikliklerinin hesapverebilirlikte dikkate alınmaması da
eğitim kurumlarının adaletli bir çerçevede hesap vermelerini zorlaştırmaktadır.
Bu doğrultuda ülkemiz eğitim sistemi açısından eşitlik temelinde bir
hesapverebilirlik mevzuat alt yapısının oluşturulması yararlı olacaktır.
Negotiating informal elder care, migration and exclusion: the case of a Turkish immigrant community in Belgium
Authors: De Tavernier Wouter , Draulans Veerle
Published: January 2019

In this article, we analyse the role exclusion plays in three theories explaining the provision of informal care for the elderly: norms and roles (sociological institutionalism), the availability and accessibility of formal care (rational choice institutionalism) and concerns about balancing time and money (rational choice theory). Feeding into the discussion on agency in old-age exclusion literature, we argue that exclusion shapes informal care provision in all three theories: social exclusion enforces norms, civic exclusion hinders appropriate formal care provision and economic exclusion reduces the opportunity costs of informal care. Hence, exclusion structures positions and power relations in care negotiation processes. The study shows that exclusion should not only be analysed as an outcome but also as a force shaping the life conditions of older people. The argument is supported using data from qualitative interviews with stakeholders in informal elder care in a Turkish immigrant community in Belgium. Intersections of gender, generation and migration status are taken into account.

Published: January 2019

Forage production in northern latitudes is challenging and uncertain in the future. In this case-study, the integrated farm system model (IFSM) was used to assess the impact of climate change and cropland expansion scenarios on forage production in a dairy farm in Newfoundland, Canada. Climatic projections indicated increases in temperature in the recent past (1990–2016) and under any future climate (2020–2079), thus enhancing agronomic performance. Temperature increases ranged from 2.8 °C to 5.4 °C in winter and from 3.2 °C to 6.4 °C in spring. Small precipitation increases (<10%) create narrower time windows to perform farm operations in the already stringent condition of excess moisture in the region. Results of land use scenarios including expansions of 20, 30, and 40% in cropland area, out of which 5% was dedicated to corn silage and the remainder to grass-legume mixtures, indicated increased yield and total production. Improvements in grass-legume yield ranged from 8% to 52%. The full range of production increases ranged from 11% to 105%. Increments in corn silage yield ranged from 28% to 69%. Total farm corn silage production increases ranged from 29% to 77%. An attainable cropland expansion of 20% would enable the farm to become self-sufficient in forage production under any climate scenario.

In this contribution we present a progress report on two atomic and molecular databases, BEAMDB and MolD, which are web services at the Serbian virtual observatory (SerVO) and nodes within the Virtual Atomic and Molecular Data Center (VAMDC). The Belgrade Electron/Atom (Molecule) DataBase (BEAMDB) provides collisional data for electron interactions with atoms and molecules. The Photodissociation (MolD) database contains photo-dissociation cross sections for individual rovibrational states of diatomic molecular ions and rate coefficients for the chemi-ionisation/recombination processes. We also present a progress report on the major upgrade of these databases and plans for the future. As an example of how the data from the BEAMDB may be used, a review of electron scattering from methane is described.
Pulsed Electric Field Extraction and Antioxidant Activity Determination of Moringa oleifera Dry Leaves: A Comparative Study with Other Extraction Techniques
Authors: Bozinou Eleni , Karageorgou Ioanna , Batra Georgia , G. Dourtoglou Vassilis , I. Lalas Stavros
Published: January 2019

The scope of this work was to determine the possibility of the application of the pulsed electric field (PEF) technique to the production of extracts from Moringa oleifera plant material (freeze-dried leaves). Various PEF conditions (pulse duration—PD; and pulse interval—PI) were tested. A field strength of 7 kV/cm was used. The total phenols in the extracts were evaluated by the Folin–Ciocalteu method and the antioxidant activity was evaluated by the radical scavenging activity (DPPH•), ferric reducing antioxidant power (FRAP) and Rancimat methods. The results were compared with those of the extracts obtained using other extraction techniques, namely microwave-assisted and ultrasound-assisted extractions, simple boiling water extraction, and plain maceration with water (as the control). The highest extraction of total phenols was achieved by the PEF procedure using 40 min treatment at a PD of 20 msec and a PI of 100 μsec. Additionally, all methods for the determination of the antioxidant activity showed that the activity of the extracts was proportional to the total phenol content. Concerning the PEF procedure, a low pulse duration with a high pulse interval is proposed in order to achieve higher extraction efficiency.
Perceptions of Change after a Trauma and Perceived Posttraumatic Growth: A Prospective Examination
Authors: Boals Adriel , Bedford Lee A. , Callahan Jennifer L.
Published: January 2019

Recent research has distinguished between actual posttraumatic growth (PTG) and perceived PTG. We used a prospective research design to measure both actual and perceived PTG in an attempt to replicate and extend previous findings. We examined college students (N = 64) who experienced a traumatic event between the start (Time 1) and end (Time 2) of a semester. We included three measures of change from pre- to post-trauma: (1) Actual PTG (change scores in measures of PTG domains), (2) perceived general growth (Time 2 ratings of functioning at Time 1 subtracted from actual ratings given at Time 1), and (3) perceived PTG (self-reports of PTG on the posttraumatic growth inventory). The results revealed perceived general growth and actual PTG were significantly correlated, suggesting that participants’ perceptions of change were accurate. However, perceived PTG was not significantly related to either actual PTG or perceived general growth. Further, increases in actual PTG and perceived general growth were significantly related to decreases in distress and unrelated to coping. By contrast, higher levels of perceived PTG were significantly related to increases in distress and higher levels of avoidance coping. Our results suggest perceived PTG may be more of a coping process than an accurate recall of posttraumatic change.

Published: January 2019

Recent advancements in synthesis and analysis of the composites based on silica and carbon quantum dots have revealed great potential of such systems in bioimaging, sensor, as well as solid-state lighting applications. Most of the synthetic methods for obtaining such materials are still relatively complex and costly. The aim of this work was to study the luminescent properties of silica-based composites prepared by the simple sol-gel method using low-cost silicate–citrate–(thio)ureate precursors. The glassy composites were prepared by acid hydrolysis of ethyl silicate (40%) in aqueous solution of citric acid ureates or thioureates with the citric acid-to-(thio)urea molar ratio of 1:1, 1:1.5 or 1:3. The results of spectrofluorimetric analysis have shown that heat-treated at 270 °C such silica gels upon UV excitation (with an optimum at λexc = 360 nm) emit light in a visible spectrum (400–600 nm). Upon this, photoluminescence efficiency of ureate-derived glasses (quantum yield 70.53% for 1:1.5 sample) appeared to be much higher than that for thioureate-derived glasses (quantum yield 11.25% for 1:3 sample) suggesting that the preparation conditions to obtain the glasses with optimal photoluminescence characteristics are quite different in case of urea and thiourea. Thus, citrate–ureate-derived silica glasses already demonstrate very good potential to be efficient materials for different fluorescence-related applications.

Published: January 2019

We investigate the effect of amplitude and phase noise on the dynamics of a discrete-time quantum walk and its related evolution. Our findings underline the robustness of the motion with respect to these noise sources, and can explain the stability of quantum walks that has recently been observed experimentally. This opens the road to measure topological properties of an atom-optics double kicked rotor with an additional internal spin degree of freedom.
Generation Expansion Planning Model for Integrated Energy System Considering Feasible Operation Region and Generation Efficiency of Combined Heat and Power
Authors: Ko Woong , Kim Jinho
Published: January 2019

Integrated energy systems can provide a more efficient supply than individual systems by using resources such as cogeneration. To foster efficient management of these systems, the flexible operation of cogeneration resources should be considered for the generation expansion planning model to satisfy the varying demand of energy including heat and electricity, which are interdependent and present different seasonal characteristics. We propose an optimization model of the generation expansion planning for an integrated energy system considering the feasible operation region and efficiency of a combined heat and power (CHP) resource. The proposed model is formulated as a mixed integer linear programming problem to minimize the sum of the annualized cost of the integrated energy system. Then, we set linear constraints of energy resources and describe linearized constraints of a feasible operation region and a generation efficiency of the CHP resource for application to the problem. The effectiveness of the proposed optimization problem is verified through a case study comparing with results of a conventional optimization model that uses constant heat-to-power ratio and generation efficiency of the CHP resource. Furthermore, we evaluate planning schedules and total generation efficiency profiles of the CHP resource for the compared optimization models.

Published: January 2019

Energy storage systems play a crucial role in ensuring stable operation. However, the development of system-level energy storage is hindered due to the restrictions of economy, geography, and other factors. Transitions of traditional power systems into integrated energy distribution systems (IEDS) have provided new solutions to the problems mentioned above. Through intelligent control management methods, the utilization of multi-energy-type resources both on the supply and demand sides shows the potential for equivalent storage characteristics. Inspired by the aggregation principles, this paper aims at proposing a novel model named generalized multi-source energy storage (GMSES), including the modeling and cooperation of three kinds of available resources: conventional energy storage (CES), multi-energy flow resources (MFR), and demand response resources (DRR). Compared with the conventional means of storage, GMSES can be regarded as a more cost-effective and flexible participant in the proposed hierarchical energy scheduling framework that can realize system-level storage services in IEDS. On this basis, a multi-timescale energy scheduling strategy is proposed to reshape the regulation of IEDS operations and deal with the fluctuations caused by renewable energy and loads, where the general parameter serialization (GPS)-based control strategy is utilized to select and control the responsive loads in DRR. Furthermore, a hierarchical scheduling algorithm is developed to generate the optimal set-points of GMSES. Case studies are analyzed in an electricity-gas coupled IEDS. The simulation results show that the coupled co-optimization GMSES model is conducive to achieving the goal of self-management and economical operation, while the influence of the underlying IEDS on the upper energy system is reduced, as the tie-line power fluctuations are smoothed out.
Regularized Integral Representations of the Reciprocal Gamma Function
Authors: Prodanov Dimiter
Published: January 2019

This paper establishes a real integral representation of the reciprocal Gamma function in terms of a regularized hypersingular integral along the real line. A regularized complex representation along the Hankel path is derived. The equivalence with the Heine’s complex representation is demonstrated. For both real and complex integrals, the regularized representation can be expressed in terms of the two-parameter Mittag-Leffler function. Reference numerical implementations in the Computer Algebra System Maxima are provided.

Authors: Beck Geoff
Published: January 2019

Dwarf spheroidal galaxies have long been discussed as optimal targets for indirect dark matter searches. However, the majority of such studies have been conducted with gamma-ray instruments. In this review, we discuss the very recent progress that has been made in radio-based indirect dark matter searches. We look at existing work on this topic and discuss the future prospects that motivate continued work in this newly developing field that promises to become, in the light of the up-coming Square Kilometre Array, a prominent component of the hunt for dark matter.

Published: January 2019

The IMAGINE Consortium aims to bring modeling of the magnetic field of the Milky Way to the next level by using Bayesian inference. IMAGINE includes an open-source modular software pipeline that optimizes parameters in a user-defined galactic magnetic field model against various selected observational datasets. Bayesian priors can be added as external probabilistic constraints of the model parameters. These conference proceedings describe the science goals of the IMAGINE consortium, the software pipeline and its inputs, namely observational data sets, galactic magnetic field models, and Bayesian priors.

Published: January 2019

The availability of in situ snow water equivalent (SWE), snowmelt and run-off measurements is still very limited especially in remote areas as the density of operational stations and field observations is often scarce and usually costly, labour-intense and/or risky. With remote sensing products, spatially distributed information on snow is potentially available, but often lacks the required spatial or temporal requirements for hydrological applications. For the assurance of a high spatial and temporal resolution, however, it is often necessary to combine several methods like Earth Observation (EO), modelling and in situ approaches. Such a combination was targeted within the business applications demonstration project SnowSense (2015–2018), co-funded by the European Space Agency (ESA), where we designed, developed and demonstrated an operational snow hydrological service. During the run-time of the project, the entire service was demonstrated for the island of Newfoundland, Canada. The SnowSense service, developed during the demonstration project, is based on three pillars, including (i) newly developed in situ snow monitoring stations based on signals of the Global Navigation Satellite System (GNSS); (ii) EO snow cover products on the snow cover extent and on information whether the snow is dry or wet; and (iii) an integrated physically based hydrological model. The key element of the service is the novel GNSS based in situ sensor, using two static low-cost antennas with one being mounted on the ground and the other one above the snow cover. This sensor setup enables retrieving the snow parameters SWE and liquid water content (LWC) in the snowpack in parallel, using GNSS carrier phase measurements and signal strength information. With the combined approach of the SnowSense service, it is possible to provide spatially distributed SWE to assess run-off and to provide relevant information for hydropower plant management in a high spatial and temporal resolution. This is particularly needed for so far non, or only sparsely equipped catchments in remote areas. We present the results and validation of (i) the GNSS in situ sensor setup for SWE and LWC measurements at the well-equipped study site Forêt Montmorency near Quebec, Canada and (ii) the entire combined in situ, EO and modelling SnowSense service resulting in assimilated SWE maps and run-off information for two different large catchments in Newfoundland, Canada.
Acute Kidney Injury Pharmacokinetic Changes and Its Impact on Drug Prescription
Authors: Blanco Victoria E. , Hernandorena Carolina V. , Scibona Paula , Belloso Waldo , Musso Carlos G.
Published: January 2019

Acute kidney injury (AKI) is a common problem in hospitalized patients that is associated with significant morbid-mortality. The impact of kidney disease on the excretion of drugs eliminated by glomerular filtration and tubular secretion is well established, as well as the requirement for drug dosage adjustment in impaired kidney function patients. However, since impaired kidney function is associated with decreased activity of several hepatic and gastrointestinal drug-metabolizing enzymes and transporters, drugs doses adjustment only based on kidney alteration could be insufficient in AKI. In addition, there are significant pharmacokinetics changes in protein binding, serum amino acid levels, liver, kidney, and intestinal metabolism in AKI, thus the determination of plasma drug concentrations is a very useful tool for monitoring and dose adjustment in AKI patients. In conclusion, there are many pharmacokinetics changes that should be taken into account in order to perform appropriate drug prescriptions in AKI patients.
A New Practical Approach for 3D Documentation in Ultraviolet Fluorescence and Infrared Reflectography of Polychromatic Sculptures as Fundamental Step in Restoration
Authors: Lanteri Luca , Agresti Giorgia , Pelosi Claudia
Published: January 2019

The aim of this work is to present a new practical approach to digital photogrammetry to obtain 3D models of polychromatic sculptures under ultraviolet fluorescence and near-infrared by starting from photographic images. This digital photogrammetry was applied recently to a 17th-century reliquary bust representing St. Rodonio, a saint particularly venerated by the Orthodox Church, presently under restoration in the Laboratories of University of Tuscia and belonging to the Museum of Colle del Duomo of Viterbo (Italy). The acquisitions of ultraviolet fluorescence and infrared frames were performed using a Nikon D5300 digital SLR camera and a modified low-cost digital camera (Samsung Model NX3300), respectively. The three-dimensional UV and IR models were obtained using Agisoft PhotoScan® software. The generated ultraviolet 3D model of the bust makes visible, in a single file, the fluorescence induced by UV radiation on the entire sculpture, highlighting surface abrasions, organic dyes, and ancient protective features. The infrared 3D model allowed for better definition of the details of the drawing used for eyes, nose and mouth definition. In conclusion, the ultraviolet fluorescence and IR 3D models of Saint Rodonio were particularly useful as documentation tools for the conservation status and for the painting construction, allowing us to perfectly map the original and restoration materials and to detect the drawing in single dynamic 3D files following a totally non-invasive, cost-effective, and rapid approach.
RUNX1-ETO: Attacking the Epigenome for Genomic Instable Leukemia
Authors: van der Kouwe Emiel , Staber Philipp Bernhard
Published: January 2019

Oncogenic fusion protein RUNX1-ETO is the product of the t(8;21) translocation, responsible for the most common cytogenetic subtype of acute myeloid leukemia. RUNX1, a critical transcription factor in hematopoietic development, is fused with almost the entire ETO sequence with the ability to recruit a wide range of repressors. Past efforts in providing a comprehensive picture of the genome-wide localization and the target genes of RUNX1-ETO have been inconclusive in understanding the underlying mechanism by which it deregulates native RUNX1. In this review; we dissect the current data on the epigenetic impact of RUNX1 and RUNX1-ETO. Both share similarities however, in recent years, research focused on epigenetic factors to explain their differences. RUNX1-ETO impairs DNA repair mechanisms which compromises genomic stability and favors a mutator phenotype. Among an increasing pool of mutated factors, regulators of DNA methylation are frequently found in t(8;21) AML. Together with the alteration of both, histone markers and distal enhancer regulation, RUNX1-ETO might specifically disrupt normal chromatin structure. Epigenetic studies on the fusion protein uncovered new mechanisms contributing to leukemogenesis and hopefully will translate into clinical applications.
