Published: August 2019

The article describes the application of optimization algorithms for solving the problem of determining the workspace of robots as a serial and parallel structure based on the tripod. The method of approximating the set of solutions of nonlinear inequalities system describing constraints on the geometric parameters of the robot and based on the concept of non-uniform coverings is considered. The internal approximations defined as a set of parallelepipeds are obtained on the basis of the method. The influence of various geometric parameters on the volume of the workspace of the robot is analyzed. To approximate the workspace, the developed algorithm and its modifications with different dimensions of parallelepipeds and approaches to the transfer of constraints from the space of input to the space of output coordinates due to the complexity of the computational problem are used. A software package in the C ++ language is developed to implement the algorithms. The results of mathematical modeling are presented. Various dimensions of the grid to calculate the functions, as well as the accuracy of the approximation are experimentally conducted. The obtained results can be used in the selection of geometric parameters of robots, which determine their limitations when moving as part of a multi-robotic system.

Published: August 2019

The article lists the types of reactors: current limiting reactors, smoothing reactor and arc suppression reactor. The principles of electrical energy conversion and methods of compensation of the electric current are described. In addition, the frequency of inspections is established including unplanned, current and capital repairs of equipment. The list is formed of the examined units, as well as the features of thermal imaging diagnostics of reactors with voltages up to and above 1000 V, including the design of a smoothed reactor with a voltage of 780 V and concrete reactor of voltage 10 kV. The thermograms of defects of contact connections are presented. The calculation of the angle dielectric loss tangent tg δ and the steady-state voltage is performed. As a result of the analysis of thermograms, the cause of defects in current limiting reactors with a voltage of 10 kV is formed. On the basis of the calculated value of tg δ, the method of reactor inspection is made; the calculation of the permissible voltage deviation based on the calculated nonlinearity coefficient is carried out. The calculation of the economic damage from the reactor failure depending on the value of the total power, current load and duration of shutdown, as well as the conclusion about the effectiveness of this type of diagnostics are made

Authors: Wilhelmus Ola Rongan
Published: August 2019

Globalisasi ekonomi dan pasar bebas merupakan di satu pihak sumber kekayaan bagi pemilik modal besar dan mereka yang memiliki akses kekuasaan, di pihak lain globalisasi menjadi sumber pemiskinan dan malapetaka bagi kebanyakan keluarga dan masyarakat kecil. Sadar akan kenyataan ini, para intelektual negara-negara berkembang sepakat bahwa globalisasi ekonomi merupakan mesin kapitalis yang memproduksi kemiskinan global karena telah merampas sebagian besar dari kekayaan dunia untuk segelintir orang. Peningkatan mutu kehidupan sosial ekonomi, pendidikan dan kesehatan masyarakat serta upaya mencari solusi atas masalah kemiskinan akibat kebijakan ekonomi global dan pasar bebas ini merupakan bagian dari misi profetis dan tanggung jawab semua agama dan umat beriman. Agama Katolik sebagai suatu institusi sosial di tengah mayarakat dunia mempunyai tugas dan tanggung jawab profetik untuk membela dan membebaskan keluarga dan masyarakat yang kurang beruntung dari kemiskinan dan ketertindasan melalui bantuan karitatif maupun pemberdayaan sosial ekonomi, politik, kesehatan dan lain-lain.

Published: August 2019

Gereja masa depan tidak bisa terpisah dari mutu pendidikan iman anak-anak saat ini. Untuk itu, sejak dini anak-anak perlu mendapat pendidikan iman yang bermutu sedini mungkin. Hal itu berarti bahwa anak-anak perlu belajar tidak hanya dengan model klasikal namun perlu dengan bentuk yang lain. Melihat hal tersebut, pendidikan yang berangkat dari pengalaman berkomunitas menjadi alternatif yang perlu dipikirkan kembali. Dalam pendidikan pengalaman  berkomunitas, setiap pribadi belajar dari pengalaman untuk bersedia saling memberikan diri bagi orang lain dan saling mendukung bagi pertumbuhan dan perkembangan setiap pribadi secara utuh.
MENDIDIK MURID MENJADI PENDIDIK IMAN
Authors: Supriyadi Agustinus
Published: August 2019

Perintah Yesus yang tersurat dalam Mat 28:19, harus dipahami sebagai kehendak Yesus supaya pengikut-pengikutNya pergi dan mengajar menjadikan murid segala bangsa. Dan setelah mereka menjadi murid dan percaya, kemuridan mereka ditandai dengan baptisan. Pewartaan tidak sekedar menjadikan orang mengerti tentang ajaran Yesus dan menerima baptisan (menjadi pengikut-Nya), tetapi terarah kepada tujuan yang lebih mendalam yaitu menjadikan orang sebagai pelaku aktif pewartaan (menjadi Pewarta/Pendidik Iman). Tugas ini memang lebih berat, sebab dalam tugas itu terkandung di dalamnya tugas mendewasakan orang agar menjadi penerus perwartaan (Pendidik Iman). Dalam rencana kehendak-Nya, Allah mau mengikutsertakan manusia dalam karya keselamatan-Nya. Setiap orang Kristiani yang telah menerima Sakramen Pembaptisan mempunyai tugas untuk menjadi pewarta dan pengajar Sabda Allah. Tugas pengajar atau pewarta adalah menghadirkan Allah dan Kerajaan-Nya melalui pengajaran atau pewartaannya. Dengan mengajar para pewarta menghantar orang kepada pengalaman cinta kasih Allah dan perjumpaan secara pribadi dengan Allah. Dalam rencana kehendak-Nva Allah mau mengikutsertakan manusia dalam karya keselamatan-Nya. Oleh karena itu, setiap orang Kristiani yang telah menerima Sakramen Pembaptisan mempunyai tugas untuk menjadi pewarta dan pengajaran sabda Allah. Melalui pengajaran diharapkan, kita dapat membangun Tubuh Kristus dan menanamkan apa yang menjadi iman Gereja dan menghantar orang lain untuk bertumbuh dalam keserupaan dengan Kristus.

Authors: Michalski Daniel , Radomyski Adam
Published: August 2019

Objectives

The authors determined the following aim of this article: identifying threats generated by air terrorism as well as characterizing the forms, methods, and manners.

Methods

Authors used theoretical methods of research. The article presents research findings with regard to the organization and operation of security systems in civil air transport. At the article, the authors focused on air terrorism and security system in the airport.

Results

The presented results of the study are not limited only to the theoretical aspects of terrorism. Authors also characterize organizational and technical undertakings that have already been implemented into security systems in aviation by national and intergovernmental institutions, responsible for its protection.

Conclusions

Regardless of the form of air terrorism and applied means, an important issue is a fact that every attempt to intercept an aerial asset is attractive for terrorists, due to the fact that each time it causes not only damage or destruction of the machine itself and the death of passengers, but it is also a real threat to airport infrastructure, installations and urban residents. In addition, the events are accompanied by high-profile media coverage.
Developing Counseling Priorities of Filipino Children in Conflict with the Law
Authors: Gomez Marie Grace A.
Published: August 2019

Philippine laws protect the rights of children in conflict with the law (CICL) detained in rehabilitation centers. Detention in such centers is not punitive in nature. Counseling is deemed as essential to their rehabilitation.

This descriptive study aims to identify educational priorities of CICL through standardized and non-standardized measures. Standardized tests included the Culture Fair Intelligence Test, the Mooney Problem Checklist and the Brainard Occupational Preference Inventory. Results show that the participants have CFIT IQ scores at the below average range, implying the need for simplified counseling methods to be employed. The top concern identified by the participants of the study is on Future Vocational and Educational Plans. Given this, the Brainard Occupational Preference Inventory was given and results show that majority (57%) had a career preference towards agriculture.

Non-standardized measures include interviews and review of case profiles of the participants. Plans after release from the center were also identified.

Youth Rural-Urban Migration in Bungoma, Kenya: Implications for the Agricultural Workforce
Authors: Eckert Elizabeth , Turner Eleanor , Yeager Sallah Jo Anne
Published: August 2019

This study provides insights into a specific, hard-to-reach youth subpopulation—those born in agricultural areas in Western Kenya who migrate to large towns and cities—that is often missed by research and development activities. Using a mixed-methods approach, we find high variability in movement of youth between rural villages, towns, and large urban areas. Top reasons for youth migration align with existing literature, including pursuit of job opportunities and education. For youth from villages where crop farming is the primary economic activity for young adults, 77 percent responded that they are very interested in that work, in contrast to the common notion that youth are disinterested in agriculture. We also find many youth interested in settling permanently in their villages in the future. This research confirms that youth migration is dynamic, requiring that policymakers and development practitioners employ methods of engaging youth that recognize the diversity of profiles and mobility of this set of individuals.
Presolar Silicon Carbide Grains of Types Y and Z: Their Molybdenum Isotopic Compositions and Stellar Origins

We report Mo isotopic compositions of 37 presolar SiC grains of types Y (19) and Z (18), rare types commonly argued to have formed in lower-than-solar metallicity asymptotic giant branch (AGB) stars. Direct comparison of the Y and Z grain data with data for mainstream grains from AGB stars of close-to-solar metallicity demonstrates that the three types of grains have indistinguishable Mo isotopic compositions. We show that the Mo isotope data can be used to constrain the maximum stellar temperatures (T
MAX) during thermal pulses in AGB stars. Comparison of FRUITY Torino AGB nucleosynthesis model calculations with the grain data for Mo isotopes points to an origin from low-mass (∼1.5–3 M
⊙) rather than intermediate-mass (>3–∼9 M
⊙) AGB stars. Because of the low efficiency of 22Ne(α, n)25Mg at the low T
MAX values attained in low-mass AGB stars, model calculations cannot explain the large 30Si excesses of Z grains as arising from neutron capture, so these excesses remain a puzzle at the moment.
The Climates of Other Worlds: A Review of the Emerging Field of Exoplanet Climatology∗
Authors: Shields Aomawa L.
Published: August 2019

The discovery of planets orbiting stars other than the Sun has accelerated over the past decade, and this trend will continue as new space- and ground-based observatories employ next-generation instrumentation to search the skies for habitable worlds. However, many factors and processes can affect planetary habitability and must be understood to accurately determine a planet’s habitability potential. While climate models have long been used to understand and predict climate and weather patterns on the Earth, a growing community of researchers has begun to apply these models to extrasolar planets. This work has provided a better understanding of how orbital, surface, and atmospheric properties affect planetary climate and habitability; how these climatic effects might change for different stellar and planetary environments; and how the habitability and observational signatures of newly discovered planets might be influenced by these climatic factors. This review summarizes the origins and evolution of the burgeoning field of exoplanet climatology, discusses recent work using a hierarchy of computer models to identify those planets most capable of supporting life, and offers a glimpse into future directions of this quickly evolving subfield of exoplanet science.
Shattering of Cosmic Sheets due to Thermal Instabilities: A Formation Channel for Metal-free Lyman Limit Systems
Authors: Mandelker Nir , van den Bosch Frank C. , Springel Volker , van de Voort Freeke
Published: August 2019

We present a new cosmological zoom-in simulation, where the zoom region consists of two halos with virial mass M
v ∼ 5 × 1012
M
⊙ and an approximately megaparsec long cosmic filament connecting them at z ∼ 2. Using this simulation, we study the evolution of the intergalactic medium in between these two halos at unprecedented resolution. At 5 ≳ z ≳ 3, the two halos are found to lie in a large intergalactic sheet, or “pancake,” consisting of multiple coplanar dense filaments along which nearly all halos with M
v > 109
M
⊙ are located. This sheet collapses at z ∼ 5 from the merger of two smaller sheets. The strong shock generated by this merger leads to thermal instabilities in the postshock region, and to a shattering of the sheet resulting in ≲ kiloparsec-scale clouds with temperatures of T ≳ 2 × 104 K and densities of n ≳ 10−3 cm−3, which are pressure confined in a hot medium with T ∼ 106 K and n ≳ 10−5 cm−3. When the sheet is viewed face-on, these cold clouds have neutral hydrogen column densities of N
H i
 > 1017.2 cm−2, making them detectable as Lyman limit systems, though they lie well outside the virial radius of any halo and even well outside the dense filaments. Their chemical composition is pristine, having zero metallicity, similar to several recently observed systems. Since these systems form far from any galaxies, these results are robust to galaxy formation physics, resulting purely from the collapse of large-scale structure and radiative cooling, provided sufficient spatial resolution is available.

Transiting Exoplanet Survey Satellite (TESS) observations have revealed a compact multiplanet system around the sixth-magnitude star HR 858 (TIC 178155732, TOI 396), located 32 pc away. Three planets, each about twice the size of Earth, transit this slightly evolved, late F-type star, which is also a member of a visual binary. Two of the planets may be in mean motion resonance. We analyze the TESS observations, using novel methods to model and remove instrumental systematic errors, and combine these data with follow-up observations taken from a suite of ground-based telescopes to characterize the planetary system. The HR 858 planets are enticing targets for precise radial velocity observations, secondary eclipse spectroscopy, and measurements of the Rossiter–McLaughlin effect.
LOFAR Discovery of a Radio Halo in the High-redshift Galaxy Cluster PSZ2 G099.86+58.45

In this Letter, we report the discovery of a radio halo in the high-redshift galaxy cluster PSZ2 G099.86+58.45 (z = 0.616) with the LOw Frequency ARray (LOFAR) at 120–168 MHz. This is one of the most distant radio halos discovered so far. The diffuse emission extends over ∼1 Mpc and has a morphology similar to that of the X-ray emission as revealed by XMM-Newton data. The halo is very faint at higher frequencies and is barely detected by follow-up 1–2 GHz Karl G. Jansky Very Large Array observations, which enable us to constrain the radio spectral index to be α ≲ 1.5–1.6, i.e., with properties between canonical and ultra-steep spectrum radio halos. Radio halos are currently explained as synchrotron radiation from relativistic electrons that are re-accelerated in the intracluster medium by turbulence driven by energetic mergers. We show that in such a framework radio halos are expected to be relatively common at ∼150 MHz (∼30%–60%) in clusters with mass and redshift similar to PSZ2 G099.86+58.45; however, at least two-thirds of these radio halos should have a steep spectrum and thus be very faint above ∼1 GHz frequencies. Furthermore, because the luminosity of radio halos at high redshift depends strongly on the magnetic field strength in the hosting clusters, future LOFAR observations will also provide vital information on the origin and amplification of magnetic fields in galaxy clusters.
Molecular cytogenetic characterization and phylogenetic analysis of four Miscanthus species (Poaceae)
Authors: Tang Yan-Mei , Xiao Liang , Iqbal Yasir , Liao Jian-Feng , Xiao Long-Qian , Yi Zi-Li , She Chao-Wen
Published: August 2019

Chromosomes of four Miscanthus (Andersson, 1855) species including M. sinensis (Andersson, 1855), M. floridulus (Schumann & Lauterb, 1901), M. sacchariflorus (Hackel, 1882) and M. lutarioriparius (Chen & Renvoize, 2005) were analyzed using sequentially combined PI and DAPI (CPD) staining and fluorescence in situ hybridization (FISH) with 45S rDNA probe. To elucidate the phylogenetic relationship among the four Miscanthus species, the homology of repetitive sequences among the four species was analyzed by comparative genomic in situ hybridization (cGISH). Subsequently four Miscanthus species were clustered based on the internal transcribed spacer (ITS) of 45S rDNA. Molecular cytogenetic karyotypes of the four Miscanthus species were established for the first time using chromosome measurements, fluorochrome bands and 45S rDNA FISH signals, which will provide a cytogenetic tool for the identification of these four species. All the four have the karyotype formula of Miscanthus species, which is 2n = 2x = 38 = 34m(2SAT) + 4sm, and one pair of 45S rDNA sites. The latter were shown as strong red bands by CPD staining. A non-rDNA CPD band emerged in M. floridulus and some blue DAPI bands appeared in M. sinensis and M. floridulus. The hybridization signals of M. floridulus genomic DNA to the chromosomes of M. sinensis and M. lutarioriparius genomic DNA to the chromosomes of M. sacchariflorus were stronger and more evenly distributed than other combinations. Molecular phylogenetic trees showed that M. sinensis and M. floridulus were closest relatives, and M. sacchariflorus and M. lutarioriparius were also closely related. These findings were consistent with the phylogenetic relationships inferred from the cGISH patterns.
Intensively Delivered Cognitive-Behavioral Therapies: An Overview of a Promising Treatment Delivery Format for PTSD and Other Mental Health Disorders
Authors: Held Philip , Bagley Jenna M. , Klassen Brian J. , Pollack Mark H.
Published: August 2019

Although cognitive-behavioral therapy (CBT) is considered a treatment of choice for a variety of mental health conditions, many patients who could benefit either do not initiate treatment or they drop out early. Intensive models, in which CBT is delivered in multiple sessions per day over the course of 1 to 3 weeks, may be a promising model to address both underuse of CBT and premature dropout, but many questions remain about the clinical utility and feasibility of intensively delivered CBT. In this brief overview, we consider evidence that various models of intensively delivered CBT are associated with promising outcomes, low rates of patient drop out, and high rates of patient satisfaction. Directions for future research are also discussed

Virtual Reality Exposure Therapy for Posttraumatic Stress Disorder
Authors: Sherrill Andrew M. , Rothbaum Alex O. , McSweeney Lauren B. , Rothbaum Barbara O.
Published: August 2019

Virtual reality exposure therapy (VRE) for posttraumatic stress disorder (PTSD) is an innovative and increasingly popular approach to delivering trauma-focused exposure therapy to a range of populations exposed to trauma. VRE is best viewed as another medium for prolonged exposure (PE), which is the most extensively researched treatment for PTSD and is one of the universally recommended psychotherapies in clinical practice guidelines. The unique application of VRE is imaginal exposure to the trauma memory conducted with the eyes open within a VR environment to help activate and sustain the memory sufficiently. Since its proof of concept over two decades ago, the availability and acceptability of VR technologies in the context of mental health treatment has greatly increased. This article describes the theory, evidence, and procedures of VRE. Clinicians interested in VRE are encouraged to pursue appropriate training and consultation.

Medication Competence, Numeracy, and Health Literacy
Authors: Gutierrez Kevin M. , Cohn Lawrence D.
Published: August 2019

Two studies investigated the association between medication literacy and numeracy. Study 1 revealed an association between both variables in a sample of adults. Study 2 replicated the finding in a sample of parents of young children, even after controlling for level of parental health literacy. Both studies employed the Medication Literacy in Spanish and English (MedLitRxSE) assessment tool. Objective and subjective numeracy scores were significantly correlated with MedLitRxSE scores in both studies, suggesting that interventions for reducing medication errors might benefit by simplifying the numerical information presented in medication instructions.

Transnational Human Trafficking
Authors: Gupta Pallavi
Published: August 2019

Human trafficking is a pernicious new variation on the ancient theme of slavery and trading in human flesh. It is considered a serious organised crime against humanity, reduces their sense of worth and punctures their ego and sense of dignity. Human trafficking is a transnational crime, a global problem that targets vulnerable individuals and affects every country. Its expansion depends on there being source countries with people demanding better economic living conditions, and destination countries with people or industries demanding cheap labour or cheap prostitution to enlarge their profits. The Protocol to Prevent Suppress and Punish Trafficking in Persons, especially Women and Children by United Nations marks the international community's cumulative efforts to deal with this transnational organised crime. The Trafficking Protocol was entered into force on 2003. It has been signed by 117 countries and ratified by 159 parties. This article focuses on the ambiguity of definition of human trafficking given by UNO protocol.

Corrosion Resistance of Vanadis 6 Steel after Conventional Heat Treatment and Sub-Zero Treatment in Cold Nitrogen Gas Followed by Tempering
Authors: Bartkowska Aneta , Jurči Peter
Published: August 2019

The paper presents the results of study of corrosion resistance of Vanadis 6 steel after conventional heat treatment and sub-zero treatment at-140 °C for 17 h. It was found that sub-zero treatment leads generally to decrease in corrosion current, which is in turn reflected in lower corrosion rate of the material subjected to this kind of treatment. The corrosion potential of sub-zero treated specimens was more anodic, suggesting their more noble behavior in 3.5 % NaCl water solution. This behavior was ascribed to the presence of a huge number of small globular carbides in SZT specimens, which seemed to stabilize the protective oxide films on the surfaces. Tempering reduces the corrosion resistance of the steel since this treatment produces fine precipitates of alloyed carbides that deplete the matrix by chromium and thereby destabilizes the protective films on the steel surface.
Microstructure and Microhardness of Powder Boronized Vanadis 6 Steel
Authors: Hudáková Mária , Jurči Peter
Published: August 2019

A Cr-V ledeburitic steel Vanadis 6 was powder boronized for different durations, austenitized, quenched and tempered. All the boronized layers are two-phased, i.e. they are formed by MeB and Me2B compounds. The thickness of boronized compound layers increased moderately with boronizing time. The thickness of MeB individual layer increases more rapidly, and it makes up to 50% of total layer thickness when boronized for 150 min. Boronized layers contain enhanced amount of chromium but they are almost free of other alloying elements. The MeB compound has a microhardness of around 1860 HV 0.1 after short – time boronizing but its microhardness exceeded 2100 HV 0.1 after long – time processing. The microhardness of Me2B was correspondingly lower, its values were around 1760 – 1850 HV 0.1. Transient region manifested enhanced amount of carbides, resulting from carbon transport from growing boronized layers towards the substrate. This phenomenon was reflected in elevated hardness compared to the substrate.

A NiCrBSi coating was produced on a pure iron plate by laser cladding technology. Electric-magnetic compound field was applied in order to improve the quality of coating. The effect of electric-magnetic compound field on the microstructure and the phase composition of coating was investigated by OM and XRD, respectively. The results indicated that the phase composition of the coatings were γ-(Fe,Ni), Cr23C6, Cr7C3, CrB and Ni3B with and without electromagnetic field. Microstructural observation showed that the grains were refined obviously by electromagnetic stirring. The electromagnetic stirring could change the direction of the heat dissipation and changed the direction of the columnar crystal at the bottom of the coating. High qualitative coating without porosity were obtained under electromagnetic field.

To further study the formation and corrosion mechanisms of AM60B vanadate films, a vanadate coating was synthesized on AM60B substrate via a chemical conversion at 50°C. The morphologies of the films and the corrosion samples were observed by using scanning electron microscopy(SEM), energy dispersive X-ray analysis(EDAX) was used to analyze the elemental distribution of the film surface and the Electrochemical Impedance Spectroscopy(EIS) and the polarization curves of the films were tested by an electrochemical workstation. The morphology of conversion film is layered structure with white balls. V element preferentially deposits near the base end and the V-rich phase is easily generated on the β-phase(Mg17Al12). In the course of corrosion, corrosion begins near the α-phase(Mg). During the processes of observation and analysis, the concept of micro-zone pH gradients was discovered and applied, and attempts were made to explain some observed phenomena by using this concept. The results show that the concept of pH gradients in micro zones can be used to explain the film formation and corrosion mechanisms well.

This research is to analyze the effect of mechanical milling on the microstructure and mechanical properties of copper-iron. The sample is fabricated by compacting, milling and sintering processes. Sintering process is carried out using continuous type machine with conveyor belt mesh and the furnace type is muffle. After that, it is cooled with natural water jacket process. Vicker hardness testing and tensile strength test is performed to determine the mechanical properties of copper-iron alloys that occur. The mean value of sample 1 hardness (before milling) was 39.8 HV. The mean value of sample hardness 2 (after milling) was 74.9 HV. The value of the yield strength (σ) of sample 1 is 17.597MPa, and the value of ductility (ε) is 0.119. The value of the yield strength (σ) of sample 2 is 18.547 MPa, and the value of ductility (ε) is 0.073. The test results and analysis showed that by shrinking the size of metal powder, by milling for 2 hours, the hardness and yield strength of the product can increase. Although, the product becomes more brittle which is indicated by the decreased ductility value.

In order to improve the dynamic stability of precision micro slitting turn-milling machine tools, reduce or avoid the vibration problem during the cutting process, optimize the machine structure and processing parameters, the modal analysis of precision micro slitting turn-milling machine tool based on hammer experimental method was researched. In this paper, by analyzing the mechanism of precision micro slitting turn-milling machine tools, the multi degree-of-freedom mathematical vibration model of precision slitting turn-milling machine tools is constructed. The precision micro turn-milling machine tool is analyzed based on the hammer experiment analysis. The modal analysis obtained the first five natural frequencies and resonance speeds of the precision micro slitting turn-milling machine tool,including ST26, NN-25UB8K2 and NN-20UB87. The research results show that hammer experimental method can evaluate the vibration modal analysis of precision micro slitting turn-milling machine tools to some extent. The experimental modal analysis results guide and optimize the structural design and processing technology of precision micro slitting turn-milling machine tools.
Angle-Resolved Spectroscopy Study of Ni-Based Superconductor SrNi2P2
Authors: Yan Y. F.
Published: August 2019

We performed an angle-resolved photoemission spectroscopy (ARPES) study of the Ni-based superconductors SrNi2P2. We observe both electron and hole Fermi surface pockets with different shapes and sizes which leads to very poor nesting conditions. Moreover, we observe a band structure reconstruction below the structural transition temperature (325 K), with bands shifting downwards and one extra hole-like band appearing around Г. These behaviors might be attributed to the length reduction of one third of P-P bonds between the adjacent NiP layers. The low temperature phase in SrNi2P2 can be regarded as a partially collapse phase. Our result may facilitate understanding the collapsed behavior which is important to unveil superconductivity mechanism in iron-based superconductors.
Level of knowledge, attitudes and beliefs towards patients with chronic low back pain among final year School of Therapeutic Sciences students at the University of the Witwatersrand – A cross-sectional study

Background: Knowledge of neurophysiology of pain influences healthcare providers’ attitudes and beliefs about patients with chronic low back pain which affect management choices.Objectives: The aim of this study was to determine the level of knowledge of pain and attitudes and beliefs towards patients with chronic low back pain among final year undergraduate students from the School of Therapeutic Sciences at the University of the Witwatersrand.Methods: This cross-sectional study included two questionnaires – Health Care Providers’ Pain and Impairment Relationship Scale (HC-PAIRS) for measuring attitudes and beliefs about pain and the Neurophysiology of Pain Questionnaire (NPQ) for knowledge of pain. These were distributed to 224 students. An analysis of variance and a two-sided t tests compared data with p ≤ 0.05.Results: The study had a 65% response rate (n = 145), of which the majority were female students (n = 115, 79%). Overall, the mean correct NPQ score was 6.01 (± 1.98), with a significant difference among the programmes (p = 0.005). Mean NPQ scores for each programme were as follows: physiotherapy 6.97 (1.77), biokinetics 6.31 (2.43), exercise science 6.25 (2.5), pharmacy and pharmacology 5.69 (1.39), nursing 5.32 (1.39) and occupation therapy 5.21 (2.09). The mean correct scores for HC-PAIRS were 63.1 (8.9), with significantly higher scores in females than males (p = 0.04). Knowledge scores had a low inverse relationship with scores for attitudes and beliefs towards patients with chronic low back pain (r = -0.304; p = 0.0002).Conclusion: There is a deficit in knowledge of pain among final year students in the School of Therapeutic Sciences, with a low correlation with attitudes and beliefs towards patients with chronic low back pain. Therefore, improving the knowledge of pain might result in a change in these attitudes and beliefs.Clinical implications: The results have shown an association between knowledge of pain and attitudes and beliefs towards patients with chronic low back pain. Therefore, knowledge is one of the factors that could contribute in changing the attitudes.

Multiple primary malignancies are defined as two or more primary malignant tumors diagnosed in one individual; they are further classified to synchronous or metachronous based on the period between each cancer diagnosis and the other. The diagnosis of four synchronous cancers is exceedingly rare. We report a case of a 72-year-old man, diagnosed with synchronous quadruple cancers, Hurthle cell carcinoma and papillary carcinoma of the thyroid, as well as squamous cell carcinoma and carcinoid tumor of the lung.

Published: August 2019

The coexistence of gastrointestinal (GI) stromal tumors (GISTs) and other malignancies, both synchronous or metachronous, has been discussed extensively in literature. It has also been described that the frequency of malignancies among patients with GIST is significantly higher than that in the general population. We present a case report of a patient with synchronous occurrence of myelodysplastic syndrome (MDS) and a GIST who presented with chronic fatigue and an episode of syncope and was found to have obscure GI bleed. Laboratory investigations revealed severe anemia, marrow picture was suggestive of MDS, and magnetic resonance imaging of the abdomen revealed a proximal small bowel neoplasm. She underwent resection of the diseased segment and anastomosis. The histopathology of the specimen confirmed the diagnosis of a GIST arising from the jejunum. She was started on imatinib on postoperative day 21 and is presently well preserved and on regular follow-up. The possibility of small bowel neoplasm, especially GIST, must be considered in patients diagnosed with chronic anemia secondary to obscure GI bleed and the possibility of a synchronous GIST, although uncommon must be considered in patients with myeloproliferative disorders and leukemia.
