A method to obtain orientation curves in Euler space for a seccond diffraction process in polycrystals
Authors: Palacios Gómez Jesús , Salat Figols R.S. , Kryshtab T. 
Published: June 2018

A method is presented to obtain the orientation curve in the Eulerian space, of crystallites which diffract in one point of a Debye-Scherer ring in a second diffraction process. The incident beam is therefore the reflected beam of a previous diffraction process, and the sample has a general orientation for a pole figure measurement, given as usual by two angles, χ around the sample Y axis, and φ around the sample normal. Two solutions are found for all secondary reflections. The method proposed here was outlined somewhere else for the measurement of pole figures by neutron diffraction [1], and here important improvements are made, especially regarding the mathematical methods.

Origin of the Modulation of the Radio Emission from the Solar Corona by a Fast Magnetoacoustic Wave
Authors: Kolotkov Dmitrii Y. , Nakariakov Valery M. , Kontar Eduard P. 
Published: June 2018

Abstract
Observational detection of quasi-periodic drifting fine structures in a type III radio burst associated with a solar flare SOL2015-04-16T11:22, with the LOw Frequency ARray (LOFAR), is presented. Although similar modulations of the type III emission have been observed before and were associated with the plasma density fluctuations, the origin of those fluctuations was unknown. Analysis of the striae of the intensity variation in the dynamic spectrum allowed us to reveal two quasi-oscillatory components. The shorter component has an apparent wavelength of ∼2 Mm, phase speed of ∼657 km s−1, which gives an oscillation period of ∼3 s, and a relative amplitude of ∼0.35%. The longer component has a wavelength of ∼12 Mm and relative amplitude of ∼5.1%. The short frequency range of the detection does not allow us to estimate its phase speed. However, the properties of the shorter oscillatory component allowed us to interpret it as a fast magnetoacoustic wave guided by a plasma nonuniformity along the magnetic field outwards from the Sun. The assumption that the intensity of the radio emission is proportional to the amount of plasma in the emitting volume allowed us to show that the superposition of the plasma density modulation by a fast wave and a longer-wavelength oscillation of an unspecified nature could readily reproduce the fine structure of the observed dynamic spectrum. The observed parameters of the fast wave give an absolute value for the magnetic field in the emitting plasma of ∼1.1 G, which is consistent with the radial magnetic field model.
Worker knowledge of occupational legislation and related health and safety benefits
Authors: Pilusa Mogale L. , Mogotlane Mataniele S. 
Published: June 2018

Background: Environmental hazards such as fumes, gases, poor ventilation and extreme temperatures might lead to occupational illnesses and injuries. To protect workers from potential occupational health and safety risks, the government has promulgated occupational legislation that must be implemented in work settings.Objectives: The objective of this study was to explore the knowledge of workers about occupational legislation and its benefits for their health and safety. The aim was to make recommendations that would be implemented to improve the knowledge and compliance with occupational legislation as advised by the occupational health nurse.Methods: A quantitative approach was used for this study. One hundred and ten respondents were sampled from an accessible population of 1590 workers. A self-administered questionnaire was used for gathering data. Data were analysed through descriptive analysis using Statistical Package for Social Sciences.Results: Research findings indicated that only 18 (16.36%) respondents were knowledgeable about occupational legislation. Eighty-two (75.54%) respondents were unable to mention even one occupational act by name. Respondents mentioned five benefits of occupational legislation for the health and safety of workers. These benefits were that legislation ensured safety, gave rights to workers, ensured compensation for occupational injuries and illnesses, and provided guidance in the prevention of occupational injuries and illnesses.Conclusion: Most respondents (75.54%) were found not to be knowledgeable about occupational legislation. The positive finding was that respondents knew the benefits of occupational legislation. To improve the respondents’ knowledge about legislation, five recommendations are made by the researcher.
Caregivers’ reading practices to promote literacy in a South African children’s home: Experiences and perceptions
Authors: Tayob Faadhilah , Moonsamy Sharon 
Published: June 2018

Background: Exposure to social trauma influences the psychosocial experiences of vulnerable children. This affects their positive development, consequentially resulting in poor scholastic progress. South Africa’s history of inequality and injustice has compounded the current social, educational and economic situation, highlighting the need for research on children in care. A paucity of published studies exists on caregiver facilitation of literacy skills among vulnerable populations in South African children’s homes. The purpose of this paper is to describe the reading practices that caregivers in one children’s home (orphanage) used to promote literacy development. Method: An exploratory, descriptive contextual design was implemented, using inductive and interpretative approaches. Semi-structured interviews and focus group discussion were conducted. Ten caregivers, who supervised children aged 9–10 years at the home, consented to be participants. Applied content thematic analysis was used to interpret the data obtained. Findings: The caregivers at the children’s home were implementing some reading strategies, but they did not engage sufficiently in self-reflection on the reading processes. The caregivers used relevant reading strategies, such as asking questions to develop understanding and memory recall. They encouraged dialogue through characterisation, where the children acted out the roles of the main characters. These reading strategies demonstrate the quality of the mediation. Conclusions: Speech–language therapists have a role in prevention and promotion programmes in children’s homes. They should advocate for, collaborate on and support caregivers’ facilitation of early literacy skills in these homes, as the link between literacy and language cannot be ignored. Providing guidelines and sharing knowledge on reading instruction for the children are essential in improving the literacy rates in vulnerable populations. Language and literacy interventions are only effective and meaningful if the social and cultural contexts are considered. Such interventions would add value and constitute a step towards redressing past inequalities in South Africa. These results contribute to our understanding of context when developing literacy programmes. The sample size was a limitation. However, the aim was not about generalisation but to gain an insight into caregiver reading practices so that literacy programmes are built on these strengths.
Idiopathic chondrolysis of hip in children: New proposal and implication for radiological staging
Authors: Amarnath C , Muthaiyan Priya , Mary T Helen , Mohanan Shilpa , Gopinathan K 
Published: June 2018

AbstractPurpose: Our objective was to evaluate the radiological appearances in different stages of idiopathic chondrolysis of hip (ICH) which will be helpful in the early diagnosis and guiding appropriate treatment for this condition to prevent progression of disease. Materials and Methods: We evaluated 14 patients of ICH in varying stages: Stage 1 (n = 9), Stage 2 (n = 3), Stage 3 (n = 2). Average age at presentation was 10–11 years. Plain radiograph and magnetic resonance imaging (MRI) was done in all these patients. Results: In the current study, we have attempted to stage ICH based on the radiological progression of the disease, where MRI was used as the primary tool. Stage 1 showed a wedge-shaped hyperintensity in T2 weighted (T2W) and hypointensity in T1 weighted (T1W) images involving the middle one-third of the femoral head and it is the earliest and characteristic finding in MRI. Associated findings like joint space narrowing, synovial hypertrophy with joint effusion may also be observed. Stage 2 showed acetabular edema in the affected hip in addition to the above-mentioned findings. Stage 3 showed more extensive involvement of femoral head and acetabulum, with collapse of the femoral head, degenerative changes in hip, early osteoporotic changes, and ultimately loss of joint space. Conclusion: Imaging-based staging system proves very useful in the early diagnosis, staging, and assessing the prognosis of ICH.
Morning glory syndrome with Moyamoya disease: A rare association with role of imaging
Authors: Ponnatapura Janardhana 
Published: June 2018

AbstractMorning glory disc anomaly (MGDA) is a congenital optic nerve anomaly characterized by a funnel-shaped excavation of the posterior globe that incorporates the optic disc. Most cases are isolated and not associated with systemic anomalies. Systemic anomalies include midline cranial facial defects, hypertelorism, agenesis of the corpus callosum, cleft lip and palate, basal encephalocele, congenital forebrain abnormalities, and renal anomalies. We report a case of 4-year-old male child who presented with reduced visual acuity on left eye with poor fixation. The left eye demonstrated 6-diopter esotropia. Examination of fundus revealed features of MGDA. The child was further subjected to magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of brain to rule out other associated anomalies. It demonstrated narrowing at the distal part of internal carotid artery on both sides, left more than right with prominence of lenticulostriate and leptomeningeal vessels. MRI also revealed funnel-shaped excavation of the posterior globe on the left side consistent with MGDA. Ascertaining the accurate diagnosis of MGDA guides appropriate ophthalmic management and should also prompt a search for associated intracranial abnormalities. Although the diagnosis of MGDA is typically made clinically, imaging may feed supplementary value in establishing the diagnosis and reveal the extent and character of associated ocular abnormalities, and cross-sectional imaging permits for evaluation of the globe in the setting of associated opacities of the refractive media, including persistent hyperplastic primary vitreous, which may alleviate the capacity to make this diagnosis on the basis of the fundoscopy examination alone.
Among the fibers: A multimodality imaging review of intramuscular mass lesions
Authors: Shyam Karthik , Cicilet Soumya , Philip Babu 
Published: June 2018

AbstractThe common presentations of patient complaints regarding the musculoskeletal system, such as pain, swelling, and restriction of movement, lead to the imaging discovery of various lesions often located in, or arising from, skeletal muscle in the region of interest. Knowledge of the patients’ clinical history, laboratory parameters, and various imaging characteristics of the implicated lesions would assist the radiologist in coming to a timely, reasonably accurate conclusion about the etiology of the patient’s complaints, the severity of disease, and in directing patient therapy.

Published: June 2018

AbstractAcute cholecystitis (AC) is a frequent complication of biliary cholelithiasis. Although ultrasound is the first diagnostic imaging procedure, frequently the initial imaging modality is computed tomography (CT). Therefore, familiarization of CT findings in AC and potential related complications are extremely important. This pictorial essay reviews a broad spectrum of complications related to AC and its key findings in CT.
Endovascular treatment of ruptured pica aneurysms and association with its extradural origin: A single-center experience
Authors: Mittal Somit , Singh Vivek , Phadke R. V. , Neyaz Zafar 
Published: June 2018

Abstract
Background: Posterior inferior cerebellar artery (PICA) like other intracranial arteries is prone to aneurysm formation. Aneurysms usually arise from the vertebral artery (VA)—PICA junction and the proximal segment of the PICA. The surgical clipping of PICA aneurysms can be challenging and carries a potentially significant risk of morbidity and mortality. Experience with endovascular therapy has been limited to a few studies; however, the use of endovascular therapy as an alternative treatment to surgery has been increasing. We present our experience of last 5 years in treating the ruptured PICA aneurysms. Materials and Methods: A total of 11 patients with PICA aneurysms, out of them 7 were at proximal PICA, 2 at the vertebral-PICA junction, and 1 each at mid and distal PICA, underwent endovascular treatment at our institution between 2011 and 2016. Results: All the patients presented with an acute intracranial hemorrhage, confirmed on CT head. Most of the aneurysms were at proximal PICA (anterior and lateral medullary segments) with the partial incorporation of PICA origin in the sac. Low origin of PICA was seen in 7 (out of 11) cases, out of these cases, 5 had proximal PICA, aneurysm, and one (n = 1) had VA-PICA, junction aneurysm (1/7) and. one distal PICA aneurysm. There were seven proximal PICA aneurysms, and out of them, parent vessel occlusion was done in six and selective coiling in one (n = 1) case. From seven (n = 7) proximal PICA aneurysms, there were five cases of low origin and rests showed normal course and origin. Two (n = 2) junctional aneurysms were treated with simple coiling. Low origin was seen in right VA-PICA junction aneurysm. Endovascular treatment of all the 11 aneurysms was successful. The treatment consisted of selective aneurysm coiling in four (36.3%) patients and aneurysm with parent vessel trapping in seven patients (63.6%). Out of these seven patients, in one (n = 1) patient where aneurysm was distal PICA, glue embolization was done. There was no intra-procedural rupture/contrast extravasation or any thrombo-embolic complications. Follow-up studies ranged from 6 months to 5 years. Conclusion: Endovascular therapy of ruptured proximal PICA aneurysms is possible and safe with the use of adjuvant devices and should be considered as first-line treatment.
The future of work: how G20 countries can leverage digital-industrial innovations into stronger highquality jobs growth
Authors: Annunziata Marco , Bourgeois Hendrik 
Published: June 2018

Abstract
The wave of digital-industrial innovation which begins to disrupt vast sectors of the global economy has fueled fear of a potential adverse impact on jobs and wages. This paper argues that digitalindustrial innovations make human capital more important than ever and the focus needs to shift to the complementarity between new technologies and human abilities. In particular, more effort should be devoted to (i) understanding what new skills will be needed, and how existing jobs will change; (ii) upgrading education and professional training schemes; (iii) reforming labor market institutions to support a future where a larger share of workers will change jobs and employers more frequently; (iv) reforming social benefits systems and bolstering social safety nets to smooth the economic transition and cushion the impact on the worst-affected workers. This paper presents an analysis of the challenges, addresses the key areas of action, and puts forward specific proposals, including policy actions, industry initiatives, and further research projects. The authors argue that the G20 could and should champion a comprehensive approach to leverage digital-industrial innovations for faster job creation and growth, with initiatives to re-align demand and supply of skills, labor market reforms, redesigned social safety nets, measures to promote digital innovation and facilitate the adoption of skills-augmenting technologies, and strengthened private sector training programs.

Published: June 2018

Abstract. When dairy cattle production predominates, the quantity and quality of beef
can be increased through commercial crossing of beef bulls with dairy cows
and creating herds for the purpose of beef production. This experiment was
conducted to compare carcass traits in young bulls and steers, produced by
crossing Holstein-Friesian (HF) cows with Hereford (HH) bulls and slaughtered
at 15 and 18 months of age. One half of 32 young
bulls were castrated at 2 or 3 weeks of age. Starting at 7 months of age,
they received grass silage supplemented with concentrates. At the end of the
fattening period, the animals were slaughtered, carcass quality and the
quality of meat from m. longissimus thoracis were evaluated. It was found
that unlike steers, bulls can be slaughtered at a later age because their
carcass traits improved over time and carcass fat content increased only
insignificantly. Meat from steers had higher intramuscular fat content (1.20
and 2.35 % in bulls and steers slaughtered at 15 months of age,
respectively; 1.89 and 3.79 % in bulls and steers slaughtered at 18
months of age, respectively), it was tenderer and juicier than meat from
bulls, and its sensory quality improved with age. The intramuscular fat (IMF)
of steers was characterized by a more desirable n-6 ∕ n-3 polyunsaturated
fatty acid (PUFA) ratio, whereas the IMF of bulls had higher concentrations
of conjugated linoleic acid and n-3 PUFAs. Beef from steers is a good choice
for consumers who appreciate high-quality meat. The results of this study may
encourage producers to raise steers for beef.
Vertical distributions of aerosol optical properties during the spring 2016 ARIAs airborne campaign in the North China Plain

Published: June 2018

Abstract. Vertical distributions of aerosol optical properties derived from
measurements made during 11 aircraft flights over the North China Plain (NCP)
in May–June 2016 during the Air Chemistry Research In Asia (ARIAs) were
analyzed. Aerosol optical data from in situ aircraft measurements show good
correlation with ground-based measurements. The regional variability of
aerosol optical profiles such as aerosol scattering and backscattering,
absorption, extinction, single scattering albedo (SSA), and the
Ångström exponent (α) are thoroughly
characterized for the first time over the NCP. The SSA at 550 nm showed a regional mean value of
0.85 ± 0.02 with moderate to strong absorption and the α ranged
from 0.49 to 2.53 (median 1.53), indicating both mineral dust and
accumulation-mode aerosols. Most of the aerosol particles were located in the lowest 2 km
of the atmosphere. We describe three typical planetary boundary layer (PBL)
scenarios and associated transport pathways as well as the correlation
between aerosol scattering coefficients and relative humidity (RH). Aerosol
scattering coefficients decreased slowly with height in the clean PBL
condition, but decreased sharply above the PBL under polluted conditions,
which showed a strong correlation (R2 ≥ 0.78) with ambient RH.
Back-trajectory analysis shows that clean air masses generally originated
from the distant northwestern part of China, while most of the polluted air
masses were from the heavily polluted interior and coastal areas near the
campaign region.
