Unilateral Internal Cerebral Vein Thrombosis: Case Reports and Review of the Literature
Authors: Hu Ashley , Thomas Mariam , Chaudhary Saadia , Hathout Gasser 
Published: January 2021

AbstractThe purpose of this manuscript is to present two cases of unilateral internal cerebral vein thrombosis (UICVT) and use them to review the typical imaging findings and clinical presentation, provide a differential diagnosis when presented with a unilateral thalamic lesion, and discuss current literature findings of internal cerebral vein thrombosis, including the interesting trend of left-sided involvement. Two cases of UICVT were gathered from our institutions. A literature review was then conducted, and cases in the literature were compared to look for common features. Both of our cases involved the left internal cerebral vein. A total of 7 cases of unilateral and 8 cases of bilateral internal cerebral vein thrombosis were reviewed from the literature. Of the unilateral cases, all but one were on the left, and the one on the right was in a patient with right-sided malignancy after surgical resection. Most of these cases completely resolved with anticoagulation. UICVT is an extremely rare entity, with less than 10 cases reported in the literature. The prognosis of this disease is excellent if diagnosed and treated early; however, with delayed diagnosis and treatment, this process can be fatal. This highlights the importance of keeping this diagnosis on the differential when presented with a unilateral thalamic lesion.
Stability analysis of rock slope along selected road sections from Gutane Migiru town to Fincha sugar factory, Oromiya, Ethiopia
Authors: Lamessa Gadaawin , Meten Matebie 
Published: January 2021

AbstractThe slope instability was one of the common problems along the road that connects Gutane Migiru town to Fincha sugar factory, Western Ethiopia. The effect of the problem was intense mostly; during the rainy season, that triggers different modes of rock slope failure. As a result, the road was frequently damaged and blocked by the failed rock that in turn hinders the traffic activities. Thus, this study aimed at stability analyses of the critical slope sections using kinematic and limit equilibrium methods (LEM). The estimation of the most important input parameter in LEM analyses like cohesion and friction angle along the failure plane is often intricate and cumbersome. Hence, this paper used Rocscience software to effortlessly and instantly compute cohesion and friction angle along specific failure planes and then to carry out kinematic and LEM analyses. Besides, the strength of the intact rock was determined by the Schmidt hammer in the field and point load laboratory test. According to the kinematic analysis result, the wedge mode of rock slope failure occurred at slope sections D1S2 and D1S3 though the planar mode of failure occurred at slope sections D1S4 and D4S1. The factor of safety determined under all anticipated conditions became less than and greater than one at slope sections D1S2, D1S3, D1S4, and D4S1, and this depicts an unstable and stable slope, respectively. From the analysis result, the combined effect of rainfall, steepness of the slope dip, and joint set was the main factors that caused the slope insatiability.
Experimental estimation and numerical optimization of ‘cylindricity’ error in flow forming of H30 aluminium alloy tubes

AbstractThe present article analyses the influence of flow forming input parameters on the development of “cylindricity error” in H30 aluminum alloy seamless tubes fabricated by a single pass reverse flow forming process. Measurement and control of geometrical precision in terms of cylindricity encompassing straightness and roundness are critical for the success of component manufacturing by flow forming. The experimental trials with a predefined range of input parameters conforming to the full factorial design of experiments approach have been performed, and corresponding cylindricity data have been recorded as the outcome. An empirical relation has been established between the input parameters and the cylindricity. It has been established that cylindricity value increases sharply with an increase in axial stagger contributing 39% to the outcome, whereas the percentage contributions of in-feed and feed-speed ratio are found to be less than 1%. The adequacy of the proposed model has further been analyzed and validated through the confirmation tests. In order to obtain better control over the overall process towards achieving higher productivity and accuracy, 2 meta-heuristic optimization algorithms namely, teaching and learning-based algorithm and genetic algorithm have been utilized for optimization of input process parameters to minimize cylindricity error. Both the algorithms predict that a combination of higher feed rate and lower value of axial stagger and in-feed parameters is essential to achieve the lowest cylindricity error in H30 Al alloy. Confirmatory experimental trials have been carried out to validate both the regression model and optimization, and have been found to agree well with the model predictions described herein.
The interactive pedological-hydrological processes and environmental sensitivity of a tropical isolated wetland in the Brazilian Cerrado

Published: January 2021

AbstractIn seasonal flooding isolated wetlands, the degree of wetness suggests a close synergy between soil processes, landscape evolution and hydrology along space and time. Until now, that subject has received insufficient attention despite natural wetlands supply essential environmental services to society and are surrounded by intensive agriculture that uses agrochemicals and fertilizers in their management. The objectives of this study were to propose an infiltration architecture model based on local surface and subsurface water-fluxes in isolated wetland embedded in lateritic plateau covered by savanna and qualify the environmental sensitivity as an area of aquifer recharge. Grain size, soil bulk density, and hydraulic conductivity were determined in five profiles in a soil catena. Unmanned Aerial Vehicle high-resolution images were obtained to generate a digital elevation model and discriminate areas with different vegetation, water accumulation, and environmental sensitivity. Electrical tomography was performed to unveil the soil architecture and infiltration. The soils (Plinthosols) developed on aquic conditions determine the linkage between the surface–subsurface hydrodynamics with the soil's physical properties. We have identified vertical and lateral water-flows in the soil architecture. Vertical flow occurs exclusively at the center, where the wetland is characterized as a recharge zone. Lateral flow towards the borders characterizes a discharge zone. The recharge zone is a depression surrounded by crops; therefore, it is a point of high environmental sensitivity. This hydrodynamic model is essential to support studies related to the dispersion of contaminants since soybean agriculture dominates the whole area of well-drained soils in the Brazilian Cerrado.

Published: January 2021

AbstractAccurate wear prediction on railway wheels and evolution of railway wheels profile can affect the maintenance planning. The objective of this paper is to provide a new applied method for measuring the railway wheel profile with photographing from the railway wheel to measure by image processing techniques. The aim of this new applied method is to measure the wheel profile using images taken from railway wheels and compare it with the original plan. For this purpose, images were taken by using a camera. In this study, all automatic correction options were turned off and brightness and contrast were in normal conditions. The pixel data is converted to double-type data and are placed in the range of zero and one. Then, the input image which is usually as a three-channel or RGB image is converted to a single channel or gray surface image. Images taken from wheel profiles are processed using image processing techniques. Then the lines, curves and shapes in the image are extracted as cross-sectional and continuous curves. The new applied method results by image processing method obtained show good agreement with those achieved in field measurements.

AbstractIn this editorial, we are delighted to introduce the seven papers in this Special Issue. Each article considers various aspects of how management research can assist in the achievement of the United Nations Sustainable Development Goals (SDGs) in different contexts. Starting from a desire to provide a mechanism to drive real research outcomes for management research, this editorial considers the SDGs and their implementation/adoption in universities and businesses to date. It then introduces the different contexts for management research and the SDGs explored in the seven articles in the Special Issue. Finally, in a Postscript at the end of this Special Issue, we look at current progress against the SDGs, how COVID-19 has impacted this progress and what the future may hold for the links between management research and the SDGs.
Developing a relational law of contracts: striking a balance between abstraction and contextualism
Authors: Gounari Zoe 
Published: January 2021

AbstractRelational contract theory holds that the interpretation of a contract must take full account of the context and surrounding circumstances of the parties’ bargain so as to give effect to their respective intentions. This paper argues that if a relational treatment of contracts is to be institutionalised, in the sense of being utilised in a contract dispute to determine and give effect to the parties’ intentions, then it must operate at an abstract level. That is to say, rather than using relevant context to determine what the actual parties intended in the circumstances at hand, the contextualist enquiry should ascertain the relevant context by reference to what the parties would have agreed to in the circumstances, had they properly reflected on what their self-interest requires. I discuss the merits of this proposition by reference to a number of appellate judgments, which already endorse contextualism as a response to contractual ambiguity, and I ultimately apply it to the Supreme Court's judgment in Rainy Sky SA v Kookmin Bank.
Obligations, consent and contracts in Scots law: re-analysing the basis of medical malpractice liability in light ofMontgomery v Lanarkshire Health Board
Authors: Brown Jonathan 
Published: January 2021

AbstractProfessors MacQueen and Thomson have defined ‘contract’, within Scots law, as denoting ‘an agreement between two or more parties having the capacity to make it, in the form demanded by law, to perform, on one side or both, acts which are not trifling, indeterminate, impossible or illegal’. This definition reflects the fact that Scottish contracts are underpinned by consent, rather than by ‘consideration’. This, naturally, has the potential to be of great significance within the context of physician/patient relationships, particularly since the 2006 case ofDow v Tayside University Hospitals NHS Trustacknowledged that these relationships could be contractual in nature. This observation is of renewed importance since the landmark decision inMontgomery v Lanarkshire Health Board, which found that physicians must ensure that they obtain full and freely given ‘informed consent’ from their patients, prior to providing medical services. In light of the present medical regime which requires ‘doctor and patient [to] reach agreement on what should happen’, the basis of liability for medical negligence, in Scotland, requires reanalysis: ‘To have a contract only when the patient pays is not consistent with a legal system which has no doctrine of consideration in contract’.

AbstractWe have found a class of circular radio objects in the Evolutionary Map of the Universe Pilot Survey, using the Australian Square Kilometre Array Pathfinder telescope. The objects appear in radio images as circular edge-brightened discs, about one arcmin diameter, that are unlike other objects previously reported in the literature. We explore several possible mechanisms that might cause these objects, but none seems to be a compelling explanation.
High cadence optical transient searches using drift scan imaging II: Event rate upper limits on optical transients of duration <21 ms and magnitude <6.6
Authors: Tingay Steven , Joubert Wynand 
Published: January 2021

Abstract
We have realised a simple prototype system to perform searches for short timescale optical transients, utilising the novel drift scan imaging technique described by Tingay (2020). We used two coordinated and aligned cameras, with an overlap field of view of approximately 3.7 deg

$^2$

, to capture over

$34\,000 \times 5$

second images during approximately 24 h of observing. The system is sensitive to optical transients, due to an effective exposure time per pixel of 21 ms, brighter than a V magnitude of 6.6. In our 89.7 deg

$^2$

h of observations, we find no candidate astronomical transients, giving an upper limit to the rate of these transients of 0.8 per deg

$^2$

per day, competitive with other experiments of this type. The system is triggered by reflections from satellites and various instrumental effects, which are easily identifiable due to the two camera system. The next step in the development of this promising technique is to move to a system with larger apertures and wider fields of view.

AbstractLet G be a finite group and

$\chi $
be a character of G. The codegree of

$\chi $
is

${{\operatorname{codeg}}} (\chi ) ={|G: \ker \chi |}/{\chi (1)}$
. We write

$\pi (G)$
for the set of prime divisors of

$|G|$
,

$\pi ({{\operatorname{codeg}}} (\chi ))$
for the set of prime divisors of

${{\operatorname{codeg}}} (\chi )$
and

$\sigma ({{\operatorname{codeg}}} (G))= \max \{|\pi ({{\operatorname{codeg}}} (\chi ))| : \chi \in {\textrm {Irr}}(G)\}$
. We show that

$|\pi (G)| \leq ({23}/{3}) \sigma ({{\operatorname{codeg}}} (G))$
. This improves the main result of Yang and Qian [‘The analog of Huppert’s conjecture on character codegrees’, J. Algebra478 (2017), 215–219].
STRICTLY REAL FUNDAMENTAL THEOREM OF ALGEBRA USING POLYNOMIAL INTERLACING
Authors: BASU SOHAM 
Published: January 2021

AbstractWithout resorting to complex numbers or any advanced topological arguments, we show that any real polynomial of degree greater than two always has a real quadratic polynomial factor, which is equivalent to the fundamental theorem of algebra. The proof uses interlacing of bivariate polynomials similar to Gauss’s first proof of the fundamental theorem of algebra using complex numbers, but in a different context of division residues of strictly real polynomials. This shows the sufficiency of basic real analysis as the minimal platform to prove the fundamental theorem of algebra.

AbstractSuppose G is an amenable locally compact group with lattice subgroup

$\Gamma $
. Grosvenor [‘A relation between invariant means on Lie groups and invariant means on their discrete subgroups’, Trans. Amer. Math. Soc.288(2) (1985), 813–825] showed that there is a natural affine injection

$\iota : {\text {LIM}}(\Gamma )\to {\text {TLIM}}(G)$
and that

$\iota $
is a surjection essentially in the case

$G={\mathbb R}^d$
,

$\Gamma ={\mathbb Z}^d$
. In the present paper it is shown that

$\iota $
is a surjection if and only if

$G/\Gamma $
is compact.

AbstractThe majority of psychological treatment research is dedicated to investigating the effectiveness of cognitive behavioural therapy (CBT) across different conditions, population and contexts. We aimed to summarise the current systematic review evidence and evaluate the consistency of CBT's effect across different conditions. We included reviews of CBT randomised controlled trials in any: population, condition, format, context, with any type of comparator and published in English. We searched DARE, Cochrane, MEDLINE, EMBASE, PsycINFO, CINAHL, CDAS, and OpenGrey between 1992 and January 2019. Reviews were quality assessed, their data extracted and summarised. The effects upon health-related quality of life (HRQoL) were pooled, within-condition groups. If the across-condition heterogeneity was I2 < 75%, we pooled effects using a random-effect panoramic meta-analysis. We summarised 494 reviews (221 128 participants), representing 14/20 physical and 13/20 mental conditions (World Health Organisation's International Classification of Diseases). Most reviews were lower-quality (351/494), investigated face-to-face CBT (397/494), and in adults (378/494). Few reviews included trials conducted in Asia, South America or Africa (45/494). CBT produced a modest benefit across-conditions on HRQoL (standardised mean difference 0.23; 95% confidence intervals 0.14–0.33, I2 = 32%). The effect's associated prediction interval −0.05 to 0.50 suggested CBT will remain effective in conditions for which we do not currently have available evidence. While there remain some gaps in the completeness of the evidence base, we need to recognise the consistent evidence for the general benefit which CBT offers.
The beloved icon: an Augustinian solution to the problem of sex
Authors: Kamel Onsi A. 
Published: January 2021

AbstractAugustine famously believed fallen human sex to be inescapably bound up with sinful lust. In every sexual act, lust embodies both the sin of the fall (prideful idolatry) and that sin's consequences. John C. Cavadini has extended Augustine's conception of lust to include domination, and even violence. This leaves us with a disturbing question: is sex without violence possible? Building upon Jean-Luc Marion's distinction between idol and icon, this paper locates a solution to the problem of lust in Augustine's conception of friendship. Identifying the beloved as an icon of God entails relating to the beloved without lustful domination.

Published: January 2021

SummaryThe objective of this study was to investigate any effect of cryopreservation of donated eggs on laboratorial and clinical outcomes of intracytoplasmic sperm injection (ICSI) cycles. This retrospective cohort study included 320 oocyte recipients undergoing 307 vitrified and 119 fresh oocyte recipient ICSI cycles, participating in an egg-sharing donation programme, from 2015 to 2018, in a private university-affiliated in vitro fertilization (IVF) centre. A review of donor and recipient ICSI cycles was charted. A general mixed models fit by restricted maximum likelihood, followed by Bonferroni post hoc test was used to compare the means between fresh and warm oocyte donation groups and investigate the effect of cryopreservation on recipient ICSI outcome. The main outcome measure was blastocyst development rates. Fertilization rate, high-quality embryo rates on days 2 and 3, normal cleavage speed rates on days 2 and 3, and blastocyst development rate were significantly higher for the fresh oocyte donation cycles compared with warmed oocyte donation cycles. In the egg-sharing donation programme, fertilization and embryo developmental competence were reduced when vitrified oocytes from infertile couples were used for ICSI compared with fresh oocytes.
Stereotactic body radiotherapy in Cyberknife® for partial breast irradiation: a review
Authors: De la Pinta Carolina , Fernández-Lizarbe Eva 
Published: January 2021

AbstractIntroduction:Partial breast irradiation (PBI) can reduce the volume of treatment and number of treatment sessions in low-risk breast cancer patients. Stereotactic body radiotherapy (SBRT) allows the administration of high doses per fraction thereby reducing the number of fractions and reducing the dose to the surrounding tissues. The objective of this study is to review the literature on the use of SBRT in PBI using the Cyberknife® (CK) unit.Material and methods:In this review, we analysed the literature in PubMed and MEDLINE with articles published in the last 10 years. All citations were evaluated for relevant content and validity.Results:We include articles in the English language with information about PBI, SBRT in PBI, the use of the CK unit in PBI and other applications of SBRT in breast carcinoma. A total of 68 articles were found and 28 articles were selected for inclusion in this review.Conclusions:The treatment of PBI using the CK unit has clear advantages in reducing the treatment volume, and therefore theoretically reducing side effects and good cosmetic results with adequate tumour control. However, the placement of fiducial markers is necessary, requiring an adequate learning curve for the placement of the markers and longer treatment times.

AbstractIntroduction:Paratesticular sarcoma are extremely rare malignant tumours. Unlike other sites, they tend to be lower grade and have higher propensity of lymphatic spread. They tend to fail locally and occasionally in the regional lymph nodes. In the absence of target volume delineation guidelines and technical illustration of conformal planning, we have made an attempt to illustrate conformal planning methodology and define target volume based on current evidence in a case of paratesticular sarcoma.Methods:We are presenting a case of 62-year-old male who presented with 15-cm scrotal swelling and underwent high inguinal orchidectomy with ligation of spermatic cord. Histopathology presented a well-differentiated leiomyosarcoma of epididymis. Post-operative radiotherapy target volume included the tumour bed, ipsilateral inguinal nodes and lower pelvic nodes as the clinical target volume.Conclusion:Adjuvant radiotherapy using advanced delivery technique such as volumetric arc technique can provide good dose distribution with good sparing of organs at risk. The downside of conformal radiation delivery is that it is a resource-intensive and has no established target volume delineation guidelines.
